-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The plan is to have a new RC version every couple

-be fixed without making breaking changes to the
-interface may block the release.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Numerous changes were made since Cowboy 1.0. The
-one most people care about is probably HTTP/2, but
-it&amp;#8217;s most likely not the only one worthwhile. The
-full list of changes (excluding types) can be found
-in the user guide chapter

-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;As this is not the full release just yet, please pay
-extra attention to details and report anything
-suspicious you find.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;There are still some tests failing. Most of those are
-related to standards that are not being followed perfectly
-just yet. Some of those will probably not be fixed before
-Cowboy 2.0 is released. They are edge cases and should not
-prevent interoperability.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The manual received a lot of love. It now has one page per
-function with a detailed description, arguments list, return
-value, changelog and examples. It also links to the other
-relevant manual pages: &lt;a href=&#34;https://ninenines.eu/docs/en/cowboy/2.0/manual/&#34;&gt;https://ninenines.eu/docs/en/cowboy/2.0/manual/&lt;/a&gt;&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Cowboy is now tested and supported with Erlang/OTP 19.0 or above
-on Arch Linux, FreeBSD, OSX, Ubuntu and Windows 7. Contact me

-      <description>&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Have you ever tried telling someone why they should use
-Erlang? You boast the smaller code size, the auto healing
-mechanisms, the distribution and they seem really excited.
-They wonder why they never heard about Erlang before. And
-then you show them what the code looks like. All excitement
-goes away. The smiles disappear. Their face starts
-becoming really serious.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;You lost them. You know you lost them. They comment on the
-syntax, or perhaps you do, already admitting defeat. It&amp;#8217;s
-unlike anything they have ever used before. And they will
-most likely end up not using it.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;What about people who already know what the syntax looks
-like? As soon as you mention Erlang, the topic of the syntax
-comes in. It&amp;#8217;s like nothing else matters.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Perhaps the topic of syntax didn&amp;#8217;t come up. But they&amp;#8217;re
-still not going to try Erlang because of it.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;You&amp;#8217;re probably not having these kinds of interactions at
-Erlang conferences. This doesn&amp;#8217;t happen with people who are
-already somewhat interested in, or need, the features that
-Erlang provides. With them the syntax is at worst a minor
-inconvenience.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;This happens because most developers are familiar with
-syntaxes that look nothing like Erlang. To be clear, I
-include language features and other concepts like objects
-as part of &#34;syntax&#34; here. Familiarity is a very important
-factor to drive adoption.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;You can see an example of that in the Elixir world, where
-the majority of people come from Ruby or already knew and
-liked Ruby. The 2016 survey tells us that 59% of Elixir
-developers were using Ruby primarily before. That&amp;#8217;s in
-large part because of the syntax. They will deny it of
-course and find other reasons. And yet, we don&amp;#8217;t see such
-a strong adoption of Erlang from Ruby developers, before
-or after Elixir appeared.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Side note: have you ever wondered why the Elixir community
-is, I quote, much friendlier than the Ruby community?
-Despite having much of the same people?&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Before we continue, let me be clear. I love the Erlang
-syntax. It is simple and explicit. It is powerful, especially
-when dealing with binary data. It has very few quirks.
-It has little to no ambiguity. It&amp;#8217;s great. Except for
-persuading people to use it.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Over the years I have been writing Erlang, I have seen
-very few people point out that the syntax slows down
-adoption. We have no problem with it, so why would others?
-At the same time, people coming to Erlang come to solve
-a real problem they&amp;#8217;re having, so the syntax is fairly
-secondary. Even if they hate it at first, they know they
-can solve their problems despite the syntax.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;You don&amp;#8217;t build a popular product or language by solving
-people&amp;#8217;s problems though. In general you end up solving
-some problems and creating new problems. No, you build
-a popular product by &lt;strong&gt;convincing people to use it&lt;/strong&gt;. And
-you make them stay with your product by making them
-&lt;strong&gt;commit&lt;/strong&gt; to using it.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Take MongoDB for example. It didn&amp;#8217;t become popular by
-working, or even by being practical. It wasn&amp;#8217;t performing
-its primary function and was losing people&amp;#8217;s data. That
-didn&amp;#8217;t stop it from becoming popular. Smart people would
-knowingly use a database that was losing data. Think about
-that for a minute.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;MongoDB of course had a huge marketing machine, and they
-focused on that. They helped organize many meetups all
-over the world, complete with various swag items given
-for free, including a small handbook about MongoDB. All
-people had to do was show up.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;They didn&amp;#8217;t go tell people to look at all the weaknesses
-their product had. They focused on the strengths. On
-what would convince people to try it. They would go
-to meetups, discuss with others, commit to try it (or
-try it at meetups directly), and by doing so sell MongoDB
-to themselves.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;How do we get people to meetups though? That&amp;#8217;d be the
-first step: you need to &lt;strong&gt;catch their attention&lt;/strong&gt;.
-I believe MongoDB did this using benchmark results.
-Ironic isn&amp;#8217;t it? MongoDB gets fast benchmark results
-because they lose data, and this gets everyone to buy
-into the product.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The key points to remember about this are:&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;ulist&#34;&gt;&lt;ul&gt;
-&lt;li&gt;
-&lt;p&gt;
-catch people&amp;#8217;s attention
-&lt;/p&gt;
-&lt;/li&gt;
-&lt;li&gt;
-&lt;p&gt;
-show your product&amp;#8217;s strengths
-&lt;/p&gt;
-&lt;/li&gt;
-&lt;li&gt;
-&lt;p&gt;
-make people take a commitment
-&lt;/p&gt;
-&lt;/li&gt;
-&lt;/ul&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Once they commit to something, you win. Everyone will not
-end up ultimately using your product of course, but it&amp;#8217;s
-at the very least become a consideration. It&amp;#8217;s on their
-mind. Their resolve will be stronger when they ultimately
-try it and inevitably run into issues.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Erlang&amp;#8217;s syntax is a weakness. Almost nobody looks at the
-Erlang syntax and falls in love with it at first sight.
-No, it takes time to learn it and understand how good it
-is. You need to sell Erlang to people without showing
-the Erlang syntax. If you do show it, then you need to
-hide the parts that feel alien. Function calls are OK.
-Recursion, not so much. Maps are OK. Records, not.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Avoiding code is not always possible when you try
-to sell it, especially to developers. You can however
-prepare them to accept the alien syntax by admitting
-that the syntax is not perfect before you show it.
-You can do this while praising it at the same time.
-For example, &#34;the syntax is a little out there, but
-it matches the concepts perfectly, it will all make
-sense when you start learning&#34;.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;This might not be the best introduction. Someone will
-need to A/B test it to find the one that gives the
-best results. But that should give you ideas.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;When something terrible happens, mentioning that this
-isn&amp;#8217;t the end of the world &lt;strong&gt;before&lt;/strong&gt; you tell others what
-happened will soften their reaction. When someone
-breaks your favorite item and cries over it calling
-themselves stupid, it&amp;#8217;s harder to get mad at them,
-compared to the same event with no emotional reaction.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Our behavior is largely dependent on what&amp;#8217;s at the
-top of our mind, so it&amp;#8217;s up to you to take advantage
-of this to make your case in the best conditions.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Next time you try to make someone use Erlang, remember
-that you should aim for getting a spoken commitment
-out of them, if possible before you show the syntax.
-If that&amp;#8217;s not possible, then prepare them to accept
-the flaws or the weirdness before they see them.&lt;/p&gt;&lt;/div&gt;

       <guid>https://ninenines.eu/articles/dont-let-it-crash/</guid>
-      <description>&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;We have a specific mindset when writing Erlang
-programs. We focus on the normal execution of the
-program and don&amp;#8217;t handle most of the errors that may
-occur. We sometimes call this normal execution the
-&lt;em&gt;happy path&lt;/em&gt;.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The general pattern behind writing only for the
-&lt;em&gt;happy path&lt;/em&gt;, letting the VM catch errors (writing
-them to a log for future consumption) and then
-having a supervisor restart the processes that
-failed from a clean state, has a name. We call it
-&lt;em&gt;let it crash&lt;/em&gt;; and it drives many of our design
-decisions.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;It&amp;#8217;s a really great way to program and the results
-are fantastic compared to most other programming
-languages. And yet, &lt;em&gt;let it crash&lt;/em&gt; barely convinced
-anyone that they should use Erlang. Why would that
-be?&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;You may already know that Cowboy is capable of
-handling at least 2 million Websocket connections
-on a single server. This is in large part thanks
-to the capabilities of the VM. Still, 2 million
-is good, much better than most other servers can
-do.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Cowboy is not just a Websocket server; it&amp;#8217;s also
-an HTTP and HTTP/2 server, and it handles many
-related features like long polling or the parsing
-of most request headers.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Can you guess how large the Cowboy codebase is,
-without looking at the source?&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Do make sure you have a clear answer in your mind
-before you go check.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Good, you are back. Now what were the results? If
-I am correct, you overestimated the size of Cowboy.
-Cowboy is in fact about five thousand lines of code.
-You probably thought it was at least ten thousand.
-About eighty percent of readers will have
-overestimated the size of Cowboy. And you did only
-because I mentioned it can handle millions of
-Websocket connections.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Numerous studies show this effect. Just mentioning
-the large number already prepared your mind to think
-in that direction. Repeating the number made you
-focus even more on it. Then the question asked for
-a number, which ended up larger than the reality.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The same effect can be applied to negotiation for
-example. You generally want to start by giving your
-offer (and not let the other party initiate) and
-you want to give a really large number first. You
-can also prepare your customer by mentioning an even
-larger number in the previous discussion.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;And it&amp;#8217;s not just numbers either. An experiment
-showed that just by looking at an image of clouds,
-customers of a pillow store were buying pillows
-more comfortable (and more expensive) than those
-who didn&amp;#8217;t see that image.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;This is the power of associations. It is covered in
-much larger detail in the books
-&lt;a href=&#34;https://www.amazon.com/Influence-Psychology-Persuasion-Robert-Cialdini/dp/006124189X&#34;&gt;Influence&lt;/a&gt;
-and
-&lt;a href=&#34;https://www.amazon.com/Pre-Suasion-Revolutionary-Way-Influence-Persuade/dp/1501109790&#34;&gt;Pre-suasion&lt;/a&gt;.
-I highly recommend reading those and applying what
-you learn to your daily life. I&amp;#8217;m definitely not
-a professional psychologist so take this post with
-a grain of salt.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;When selling Erlang, whether we are selling it to
-a customer or trying to convince a developer friend
-to start using it, we often talk about how Erlang
-&lt;em&gt;lets you sleep at night&lt;/em&gt;, that it is auto healing
-and always gets fantastic uptimes.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;And then we talk about &lt;em&gt;let it crash&lt;/em&gt;.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;And we describe what it means.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;We might as well just say that Erlang crashes a lot
-and then take the door. It would have the same effect.
-It doesn&amp;#8217;t even stop at programs crashing. You know
-what else crashes? Cars, planes, trains. Often with
-disastrous consequences. Is that really the message
-we want to convey?&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;They even &lt;a href=&#34;https://img.youtube.com/vi/oEUBW2lCkIk/0.jpg&#34;&gt;printed it on a t-shirt&lt;/a&gt;!
-Keep calm and let it crash. It&amp;#8217;s the kind of t-shirt
-you probably shouldn&amp;#8217;t wear in an airport, and for good
-reasons. A few people did, then realized what they were
-wearing and were not too smug about it.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;And yet this is how we sell Erlang.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;A better way would be to focus on the positives, of
-course, but also to make sure that those positives
-are phrased in a way that prevents bad associations
-to be formed in people&amp;#8217;s minds.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Instead of &lt;em&gt;let it crash&lt;/em&gt;, you can say that Erlang
-has &lt;em&gt;auto healing mechanisms&lt;/em&gt;. Healing is a good
-thing and accurately describes what happens in the
-system.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Should you need to go into more details, you will
-probably want to avoid &lt;em&gt;recover from crashes&lt;/em&gt; and
-instead say &lt;em&gt;recover from exceptions&lt;/em&gt;. Exceptions
-are a pretty neutral word and, should you explain
-what you mean by that, you can talk about exceptions
-that occur for reasons unrelated to Erlang, like
-hardware failure or network instability.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The trick is to always use positive words and
-phrases to describe Erlang, and to use external
-factors to explain how Erlang deals with failures.
-Never mention the failures internal to Erlang
-systems unless you are asked specifically, in
-which case you can say that the auto healing
-applies to all exceptions.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The &lt;em&gt;let it crash&lt;/em&gt; philosophy is great when
-learning Erlang or when writing fault-tolerant
-systems. But it&amp;#8217;s not going to convince anyone
-to use it unless they were already looking for
-it.&lt;/p&gt;&lt;/div&gt;

+      <description>We have a specific mindset when writing Erlang programs. We focus on the normal execution of the program and don&amp;#8217;t handle most of the errors that may occur. We sometimes call this normal execution the happy path.
+ The general pattern behind writing only for the happy path, letting the VM catch errors (writing them to a log for future consumption) and then having a supervisor restart the processes that failed from a clean state, has a name.</description>

-      <description>&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Cowboy &lt;code&gt;2.0.0-pre.4&lt;/code&gt; has been released!&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;This is the new recommended version of Cowboy.
-While I would not recommend putting it in production
-just yet, I do recommend you start writing new
-applications with this Cowboy version.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The most significant changes in the pre-release are:&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;ulist&#34;&gt;&lt;ul&gt;
-&lt;li&gt;
-&lt;p&gt;
-A new architecture: there now is one process per
-  connection and one process per request. This was
-  done because HTTP/2 allows running requests concurrently.
-&lt;/p&gt;
-&lt;/li&gt;
-&lt;li&gt;
-&lt;p&gt;
-Stream handlers. Every request, response and data goes
-  through stream handlers. They are meant to replace hooks
-  and more. They will be documented in a future pre-release.
-  Check &lt;code&gt;cowboy_stream&lt;/code&gt; and &lt;code&gt;cowboy_stream_h&lt;/code&gt; if interested.
-&lt;/p&gt;
-&lt;/li&gt;
-&lt;li&gt;
-&lt;p&gt;
-Numerous changes to the &lt;code&gt;cowboy_req&lt;/code&gt; interface. This
-  is very close to final. Check the manual for what changed.
-&lt;/p&gt;
-&lt;/li&gt;
-&lt;li&gt;
-&lt;p&gt;
-The Req object is no longer passed in Websocket callbacks.
-&lt;/p&gt;
-&lt;/li&gt;
-&lt;li&gt;
-&lt;p&gt;
-It is now possible to send frames directly from &lt;code&gt;websocket_init/1&lt;/code&gt;.
-&lt;/p&gt;
-&lt;/li&gt;
-&lt;li&gt;
-&lt;p&gt;
-SPDY support was removed, now that we have HTTP/2.
-&lt;/p&gt;
-&lt;/li&gt;
-&lt;li&gt;
-&lt;p&gt;
-Update Ranch to 1.3. We still depend on Cowlib master
-  for the time being.
-&lt;/p&gt;
-&lt;/li&gt;
-&lt;li&gt;
-&lt;p&gt;
-A much improved manual.
-&lt;/p&gt;
-&lt;/li&gt;
-&lt;/ul&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The manual received a lot of love. It now has one page per
-function with a detailed description, arguments list, return
-value, changelog and examples. It also links to the other
-relevant manual pages: &lt;a href=&#34;https://ninenines.eu/docs/en/cowboy/2.0/manual/&#34;&gt;https://ninenines.eu/docs/en/cowboy/2.0/manual/&lt;/a&gt;&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;I am quite proud of the manual right now. While more
-improvements can be made, what we have now is way better
-than before. Feedback for further improvements is welcome!&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;This is a significant step toward Cowboy 2.0. Almost all
-the breaking changes are in. A few more pre-releases are
-planned and will be released on a weekly basis (with exceptions).&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Cowboy is now tested and supported with Erlang/OTP 18.0 or above
-on Arch Linux, FreeBSD, OSX, Ubuntu and Windows 7. Contact me
-if you can provide permanent access to another platform for the
-purposes of testing.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Cowboy is now available from four locations:&lt;/p&gt;&lt;/div&gt;

-      <description>&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Last week-end I updated the Nine Nines website.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;I switched to &lt;a href=&#34;http://gohugo.io/&#34;&gt;Hugo&lt;/a&gt;. The site is
-now built from &lt;a href=&#34;http://asciidoc.org/&#34;&gt;Asciidoc&lt;/a&gt;
-documents. You probably saw me switch to Asciidoc
-for documentation this past year. This is the
-natural conclusion to that story. The great thing
-is that with a little bit of Makefile magic I can
-just copy the documentation files into Hugo and
-poof, they appear on the website.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;I am very happy with that new setup. I can now
-post my thoughts again. Woo! Expect regular posts
-from now on. I will try to replace my long series
-of tweets with posts.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The sections have been rearranged. There used to
-be a separate training section; now
-&lt;a href=&#34;https://ninenines.eu/services&#34;&gt;all my services&lt;/a&gt; are described in
-one page. I have also clarified my areas of
-expertise. There used to be confusion in the past,
-so now it should be clearer that I am not a
-distributed systems expert.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;On that note, if you are looking for my
-services right now, I&amp;#8217;m not available. I&amp;#8217;ll have
-to work 7 days a week for a while. Try again in a
-couple months. More on that in a future post.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The &lt;a href=&#34;https://ninenines.eu/docs&#34;&gt;documentation&lt;/a&gt; becomes a first class
-citizen. Bullet and Cowlib don&amp;#8217;t have proper
-documentation&amp;#8230; yet. I have started working on the
-Cowlib documentation, and Bullet shouldn&amp;#8217;t take too
-long. All these projects will be documented when
-Cowboy gets to 2.0, and will all be supported
-equally. Note that the Cowboy 1.0 documentation
-still has the old website templates and links.
-Don&amp;#8217;t worry about it.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The mailing lists link has been removed. I did
-announce a few months back that mailing lists were
-going to go. They&amp;#8217;re still up right now, but not
-for long. I am planning to put the archives
-read-only, link to them from a future post and
-be done with it. If you have a question, open a
-ticket on Github. Then I can just decide to leave
-the ticket open if I want to do improvements based
-on your feedback.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;I have replaced most of the &#34;we&#34; by &#34;I&#34;. I am
-a one-man company right now. Have been for a while.
-Doesn&amp;#8217;t make sense to keep a facade. I want to be
-close to users, not put a barrier between us.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The RSS changed. The old link doesn&amp;#8217;t work anymore.
-The new link is at &lt;a href=&#34;https://ninenines.eu/index.xml&#34;&gt;/index.xml&lt;/a&gt;,
-or &lt;a href=&#34;https://ninenines.eu/articles/index.xml&#34;&gt;/articles/index.xml&lt;/a&gt;
-if you only care about my posts. I guess that&amp;#8217;s the
-one most people want.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;I still have some tweaks to do, but it will take a
-while. My long term plan is to remove Bootstrap, use
-vanilla CSS and as little JS as possible. The reason
-for that is that it&amp;#8217;s cheaper than upgrading libraries
-every few years. Life is too short to spend it
-upgrading JS libraries.&lt;/p&gt;&lt;/div&gt;

-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;When looking into why the permessage-deflate tests

-and Economical UTF-8 Decoder&lt;/a&gt;. This is the C99

-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Does it look similar to you? So how did we get there?&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;I started with a naive implementation of the original. First, we
-don&amp;#8217;t need the codepoint calculated and extracted for our validation
-function. We just want to know the data is valid, so we only need to
-calculate the next state. Then, the only thing we needed to be careful
-about was that tuples are 1-based, and that we need to stop processing
-the binary when we get the state 1 or when the binary is empty.&lt;/p&gt;&lt;/div&gt;

-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The macro &lt;code&gt;?UTF8D&lt;/code&gt; is the tuple equivalent of the C array
-in the original code.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Compared to our previous algorithm, this performed about the same.
-In some situations a little faster, in some a little slower. In other words,
-not good enough. But because this new algorithm allows us to avoid a binary
-concatenation this warranted looking further.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;It was time to step into crazy land.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Erlang is very good at pattern matching, even more so than doing some
-arithmetic coupled by fetching elements from a tuple. So I decided I was
-going to write all possible clauses for all combinations of &lt;code&gt;C&lt;/code&gt;
-and &lt;code&gt;State&lt;/code&gt;. And by write I mean generate.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;So I opened my Erlang shell, defined the variable &lt;code&gt;D&lt;/code&gt; to be
-the tuple &lt;code&gt;?UTF8D&lt;/code&gt; with its 400 elements, and then ran the
-following expression (after a bit of trial and error):&lt;/p&gt;&lt;/div&gt;

-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The result is a 2304 lines long file, containing 2304 clauses.
-People who pay attention to what I say on Twitter will remember
-I said something around 3000 clauses, but that was just me not
-using the right number of states in my estimate.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;There was a little more work to be done on this generated
-code that I did using regular expressions. We need to recurse
-when the resulting state is not 1. We also need to stop when
-the binary is empty, making it the 2305th clause.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Still, 2305 is a lot. But hey, the code did work, and faster
-than the previous implementation too! But hey, perhaps I could
-find a way to reduce its size.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Removing all the clauses that return 1 and putting a catch-all
-clause at the end instead reduced the number to about 500, and
-showed that many clauses were similar:&lt;/p&gt;&lt;/div&gt;

+      <description>Yesterday I pushed Websocket permessage-deflate to Cowboy master. I also pushed a change in the way the code validates UTF-8 data (required for text and close frames as per the spec).
+ When looking into why the permessage-deflate tests in autobahntestsuite were taking such a long time, I found that autobahn is using an adaptation of the algorithm named Flexible and Economical UTF-8 Decoder. This is the C99 implementation:

-many great points and I am in agreement with most of it.
-This made me want to properly explain my point of view with
-regard to open source and contributions. Unlike most open
-source evangelism articles I will not talk about ideals or
-any of that crap, but rather my personal feelings and
-experience.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;I have been doing open source work for quite some time.
-My very first open source project was a graphics driver

-&lt;a href=&#34;http://ngemu.com/threads/gstaris-0-6.30469/&#34;&gt;isn&amp;#8217;t
-much left to look at today&lt;/a&gt;. This was followed by a
-&lt;a href=&#34;https://github.com/extend/wee&#34;&gt;PHP framework&lt;/a&gt;
-(started long before Zend Framework was even a thing) and
-a few other small projects. None of them really took off.
-It&amp;#8217;s alright, that&amp;#8217;s pretty much the fate of most open
-source projects. You spend a lot of work and sweat and
-get very little in return from others.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;This sounds harsh but this is the reality of all open
-source projects. If you are thinking of building a project
-and releasing it as open source, you should be prepared
-for that. This is how most of your projects will feel like.
-Don&amp;#8217;t release a project as open source thinking everyone
-will pat you on the back and cheer, this won&amp;#8217;t happen. In
-fact if your project is a too small improvement over existing
-software, what many people will do is say you have NIH
-syndrome, regardless of the improvement you bring. So you
-need not to rely on other people in order to get your
-enjoyment out of building open source software.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;In my case I get enjoyment from thinking about problems
-that need solving. Often times the problems are already
-solved, but nevermind that, I still think about them and
-sometimes come up with something I feel is better and then
-write code for it. Writing code is also fun, but not as
-fun as using my brain to imagine solutions.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;You don&amp;#8217;t need thousands of users to do that. So are
-users worthless to me then? No, of course not. In fact
-they are an important component: they bring me problems
-that need solving. So users are very important to me.
-But that&amp;#8217;s not the only reason.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;I got lucky that the Cowboy project became popular.
-And seeing it be this popular, and some of my other projects
-also do quite well, made me believe I could perhaps work
-full time on open source. If I can work full time then
-I can produce better software. What I had one hour to
-work on before I can now spend a day on, and experiment
-until I am satisfied. This is very useful because that
-means I can get it almost right from the beginning, and
-avoid the million API breaking changes that occured
-before Cowboy 1.0 was released.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;To be able to work full time on open source however,
-I need money. This is a largely unspoken topic of open
-source work. The work is never free. You can download the
-product for free, but someone has to pay for the work
-itself. Life is unfortunately not free.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Large projects and some lucky people have their work
-sponsored by their employers. Everyone else has to deal
-with it differently. In my case I was sponsored for a
-while by the &lt;a href=&#34;http://leo-project.net/leofs/&#34;&gt;LeoFS&lt;/a&gt;
-project, but that ended. I also had the Farwest fundraiser,
-which was a success, although the project stalled after that.
-(Fear not, as Farwest will make a comeback as a conglomerate
-of Web development projects in the future.) After that I set
-up the &lt;a href=&#34;http://ninenines.eu/support/&#34;&gt;sponsoring scheme&lt;/a&gt;,
-which I can proudly say today brings in enough money to
-cover my food and shelter. Great!&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;This is a start, but it&amp;#8217;s of course not enough. Life
-is a little more than food and shelter, and so I am still
-looking for sponsors. This is not a very glorious experience,
-as I am essentially looking for scraps that companies can
-throw away. Still, if a handful more companies were doing
-that, not only would I be able to live comfortably, but I
-would also be able to stop worrying about the future as I
-could put money on the side for when it gets rough.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;A few companies giving me some scrap money so I could
-live and work independently is by far the most important
-thing anyone can do to help my projects, including Cowboy.
-Yes, they&amp;#8217;re even more important than code contributions,
-bug reports and feedback. Because this money gives me the
-time I need to handle the code contributions, bug reports
-and feedback.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;If Cowboy or another project is a large part of your
-product or infrastructure, then the best thing you can do
-is become a sponsor. The second best is opening tickets
-and/or providing feedback. The third best is providing
-good code contributions.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;I will not expand on the feedback part. Feedback is
-very important, and even just a high five or a retweet
-is already good feedback. It&amp;#8217;s not very complicated.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;I want to expand a little on code contributions
-however. Not long ago I ran across the term &#34;patch bomb&#34;
-which means dropping patches and expecting the project
-maintainers to merge them and maintain them. I receive
-a lot of patches, and often have to refuse them. Causes
-for refusal vary. Some patches only benefit the people
-who submitted them (or a very small number of people).
-Some patches are not refined enough to be included.
-Others are out of scope of the project. These are some
-of the reasons why I refuse patches. Having limited
-time and resources, I have to focus my efforts on the
-code used by the larger number of users. I have to
-prioritize patches from submitters who are reactive
-and address the issues pointed out. And I have to plainly
-refuse other patches.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;I believe this wraps up my thoughts on open source.
-Overall I had a great experience, the Erlang community
-being nice and understanding of the issues at hand in
-general. And if the money problem could be solved soon,
-then I would be one of the luckiest and happiest open
-source developer on Earth.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Think about it the next time you see a donation button
-or a request for funds or sponsoring. You can considerably
-improve an open source developer&amp;#8217;s life with very little
-of your company&amp;#8217;s money.&lt;/p&gt;&lt;/div&gt;

-      <description>&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;As I am away from home with little to do (some call this
-a vacation) I wanted to reflect a little on the story so far,
-or how I arrived to Erlang and got to where I am now. The
-raw personal experience. It&amp;#8217;ll be an article that&amp;#8217;s more
-about social aspect, communities and marketing a project than
-technical considerations. As a period piece, it will also
-allow me to reflect on the evolution of Erlang in recent
-years.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Once upon a time-- Okay this isn&amp;#8217;t a fairy tale. The story
-begins with a short chapter in 2010. The year 2010 started
-with a fairly major event in my life: the US servers for the
-online game I stopped playing a few months before, but was
-still involved with through its community, were closing. OMG!
-Someone found a way to log packets and started working on a
-private server; meanwhile the JP servers were still up. And
-that&amp;#8217;s pretty much it.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Fast forward a few months and it became pretty clear that
-the private server was going nowhere considering all the drama
-surrounding it-- which is actually not unusual, but it was
-more entertaining than average and the technical abilities of
-people running the project were obviously lacking so I decided
-to obtain those logged packets and look at things myself. I
-didn&amp;#8217;t want to do a private server yet, I only wanted to take
-a peek to see how things worked, and perhaps organize some
-effort to document the protocol.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;There was 10GB of logs. I didn&amp;#8217;t have an easy to use
-language to analyze them, and hex editors wouldn&amp;#8217;t cut it for
-most purposes, so I had to look elsewhere. This was a good
-opportunity to start learning this PHP killer I read about
-before, which also happens to feature syntax for matching
-binaries, called Erlang. To be perfectly honest I wouldn&amp;#8217;t
-have touched the logs if I didn&amp;#8217;t have the added motivation
-to play with and learn a new language.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;At the time it was pretty hard to learn Erlang. In my
-experience there was Joe&amp;#8217;s book (which I always recommend
-first as I believe it is the best to learn the Erlang side
-of things; but falls a little short on OTP), and there was
-about 5 chapters of LYSE. There were a couple other books
-I never managed to get into (sorry guys), and there was also
-a few interesting blogs, some of which I can&amp;#8217;t find anymore.
-Finally the #erlang IRC community was there but I was strictly
-lurking at the time.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;What a difference compared to 4 years later! (That&amp;#8217;s
-today, by the way!) Now we have more books than I can
-remember, tons of articles covering various aspects of the
-language and platform, many targeting beginners but a good
-number of them also about advanced topics. We even have a
-free online book, LYSE, with more than 30 chapters covering
-pretty much everything. Needless to say I never finished
-reading LYSE as it got written slower than I learnt.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Back to 2010. I wrote a parser for the logs, and
-aggregated those results into one CSV file per packet type
-so I could open them in Gnumeric and aggregate some more,
-but manually this time, and draw conclusions on the packet
-structures. That was pretty easy. Even for a beginner.
-Anyone can go from zero to that level in a day or two.
-Then, having mastered binary pattern matching, I wanted
-to learn some more Erlang, by making this aggregation
-faster. What I had done before worked, but I wasn&amp;#8217;t going
-to wait forever to process everything sequentially. So I
-looked and found a project called &lt;code&gt;plists&lt;/code&gt; (still exists,
-but not maintained AFAIK). I downloaded that project and
-replaced my &lt;code&gt;lists:&lt;/code&gt; calls to &lt;code&gt;plists:&lt;/code&gt;.
-Boom. In just a few minutes all logs were processed, and
-I had learnt something new.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;It is particularly interesting to note that the lack of
-a package manager or index never bothered me. Neither before
-nor after learning Erlang. My experience with package
-managers was mostly related to Ubuntu, a little Perl and
-Python, and PHP&amp;#8217;s Pear. Let&amp;#8217;s just stay polite and say it
-was always a terrible experience. So searching on the Web
-didn&amp;#8217;t feel awkward, because even if I used a tool or
-website I would have ended up doing a search or two anyway.
-This is in contrast to the package index feature in
-&lt;a href=&#34;https://github.com/ninenines/erlang.mk&#34;&gt;Erlang.mk&lt;/a&gt;,
-which is meant to simplify specifying dependencies more
-than anything: &lt;code&gt;DEPS = cowboy&lt;/code&gt;. It does not
-attempt to solve any other problem, and will only attempt
-to solve one extra problem in the near future, which is
-the discovery of packages. So expect some kind of website
-listing packages soon enough.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;I want to use this parenthese to also point out that at
-the time there was a very small number of projects out there,
-at least compared to today. While you sometimes hear people
-complain about lack of certain libraries, it is so much
-better now than it was before! The situation improves very
-quickly, so much that it&amp;#8217;s not going to be that big an issue
-soon enough.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Wanting to know more about that game&amp;#8217;s protocol, in the
-year 2010, I ended up starting to write more Erlang code to
-simulate a server and use the server to query the client and
-see what was happening, documenting the packets and so on.
-This eventually lead to a larger project implementing more
-and more until people got their hopes up for a revival of
-the game, all the while the now competing original server
-project died in a stream of drama and technical incompetence.
-Of course, I ended up doing what any good Internet citizen
-would do, I crushed people&amp;#8217;s hopes, but that&amp;#8217;s not important
-to our story. The important part is that before giving up
-on this project, I not only learnt a good deal of Erlang
-and a little deal of OTP (which I did not touch until 6
-months after I started with Erlang; see the paragraph
-about learning material above), but I also had an intriguing
-idea pop into my mind for what would become my greatest
-success yet.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The giving up part was not easy. Having had financial
-difficulties all year 2010 and part of 2009, I resolved
-to travel back to Paris to try and make it. I ended up
-sleeping in offices for 6 months, being hosted by a shady
-person, and hearing my fair share of stories about
-the dark side of business. While there I also worked for
-another company with someone who would end up becoming
-another high profile Erlang developer. The situation
-slowly improved, I started taking part in the #erlang
-IRC discussions, giving up my status of lurker and, a
-few months into 2011, started working on the Apache killer
-project: Cowboy.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;This is the part where I probably should get accused of
-racism and other fun things, but I never did. And I think
-that speaks lots about the Erlang community. In all my time
-writing Erlang code, I can count the number of conflicts I
-had with other people on a single hand. This is the nicest
-programming community I have ever seen, by far. And the
-humblest too. The Erlang community feels like Japan. And
-I love Japan. So I love the Erlang community. I can&amp;#8217;t say
-this enough. This is something that stayed true for all
-my time using Erlang, and despite the rise of alternative
-languages that are not Japan the Erlang community has
-remained very Japan.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The first published version of Cowboy was written in
-two weeks. A little before those two weeks, during, and
-a while after, pretty much everything I said on the
-Internets was that Cowboy was going to be the greatest
-HTTP server ever, that the other servers were problematic
-(and just to be clear, Yaws was rarely if ever mentioned,
-due to being in a perceived different league of &#34;full
-featured servers&#34; while Cowboy was a &#34;lightweight server&#34;),
-and that Cowboy will be the best replacement to a Mochiweb
-or Misultin application. This, alongside a lot of time
-spent on IRC telling people to use Cowboy when they were
-asking for an HTTP server to use, probably made me sound
-very annoying. But it worked, and Cowboy started getting
-its first users, despite being only a few weeks old. Of
-course, as soon as I got my very first user, I started
-claiming Cowboy had &#34;a lot of users&#34;.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Looking back today I would definitely find myself annoying,
-this wasn&amp;#8217;t just an idle comment there. For about a year,
-maybe a little more, all I ever said was that Cowboy was
-the best. This probably made me a little dumber in the
-process (as if I wasn&amp;#8217;t enough! I know). Being French, I
-sometimes would also say things quite abruptly. To stay
-polite, I probably sounded like an asshole. I learnt to
-stop being so French over time thankfully.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;I think what was most important to Cowboy at the time,
-was three things. First, it felt fresh. It was new, had new
-ideas, tried to do things differently and followed &#34;new&#34; old
-best practices (the OTP way-- which was simply too obscure
-for most people at the time). Second, it had me spending
-all my time telling people to use it whenever they were
-looking for an HTTP server. Third, it had me helping people
-get started with it and guide them all the steps of the way.
-Mostly because it didn&amp;#8217;t have a very good documentation, but
-still, hand holding does wonders.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;To be able to help people every time they had a problem,
-I did not spend all my days reading IRC. Instead I simply
-made sure to be notified when someone said &lt;code&gt;cowboy&lt;/code&gt;.
-The same way many people subscribe to alerts when their
-company is mentioned in the news. Nothing fancy.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Time went on, Cowboy grew, or as some like to say,
-completely destroyed the competition, and many people
-eventually moved from Mochiweb and Misultin to Cowboy.
-And then Roberto Ostinelli stopped Misultin development
-and told everyone to move to Cowboy. This is the most
-humble and selfless act I have ever seen in the programming
-sphere, and I only have one thing to say about it: GG.
-Thanks for the fish. He left me with the tasks of improving
-Cowboy examples, documentation and strongly believed that
-the Misultin interface was more user friendly out of all
-the servers. So I added many examples, as many lines of
-documentation as we have of code, and strongly believe
-that Cowboy 2.0 will be the most user friendly interface
-out of all servers. But only time will tell.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;With the rise of the project and the rise in the number
-of users, my previous strategy (completely incidental, by
-the way, and definitely not a well thought out plan to
-become popular) stopped working. It was taking me too much
-time. The important aspects slowly drifted. If I wanted to
-support more users, I would have to spend less time with
-each individual user. This was actually a hard problem.
-You basically have to make people understand they can&amp;#8217;t
-just come to you directly when they have a problem, they
-have to follow proper channels. It becomes less personal,
-and might be felt like you don&amp;#8217;t care about them anymore.
-You have to hurt some people&amp;#8217;s feelings at this point. It
-is quite unfortunate, and also quite difficult to do. There
-is some unwritten rule that says early adopters deserve
-more, but in the real world it never works like this. So
-I probably hurt some people&amp;#8217;s feelings at some point. But
-that&amp;#8217;s okay. Because even if you make sure to be as nice
-as possible when you tell people to go through proper
-channels from now on, some people will still get offended.
-There&amp;#8217;s nothing you can do about it.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;From that point onward the important points about the
-project was getting the documentation done, making sure
-people knew about the proper channels to get help and
-report issues, etc. Basically making myself less needed.
-This is quite a contrast with the first days, but I believe
-Cowboy made that transition successfully.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Not only did I win time by not having to hold hands with
-everyone all the time (not that I didn&amp;#8217;t like it, but you
-know, the sweat), but I also won time thanks to the increased
-project popularity. Indeed, the more users you have, the more
-annoying guys there are to tell people to use your project
-and that it&amp;#8217;s the best and everything. Which is great. At
-least, it&amp;#8217;s great if you don&amp;#8217;t pay too much attention to it.
-Sometimes people will give an advice that is, in your opinion,
-a bad advice. And that&amp;#8217;s okay. Don&amp;#8217;t intervene every time
-someone gives a bad advice, learn to let it go. People will
-figure it out. You learn by making mistakes, after all. Use
-this extra time to make sure other people don&amp;#8217;t end up
-giving the same bad advice instead. Fix the code or the
-documentation that led to this mistake. Slowly improve the
-project and make sure it doesn&amp;#8217;t happen again.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;This is my story. So far, anyway.&lt;/p&gt;&lt;/div&gt;

-      <description>&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Now that Cowboy 1.0 is out, I can spend some of my time thinking
-about Cowboy 2.0 that will be released soon after Erlang/OTP 18.0.
-This entry discusses the proposed changes to query string handling
-in Cowboy.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Cowboy 2.0 will respond to user wishes by simplifying the interface
-of the &lt;code&gt;cowboy_req&lt;/code&gt; module. Users want two things: less
-juggling with the Req variable, and more maps. Maps is the only
-dynamic key/value data structure in Erlang that we can match directly
-to extract values, allowing users to greatly simplify their code as
-they don&amp;#8217;t need to call functions to do everything anymore.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Query strings are a good candidate for maps. It&amp;#8217;s a list of
-key/values, so it&amp;#8217;s pretty obvious we can win a lot by using maps.
-However query strings have one difference with maps: they can have
-duplicate keys.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;How are we expected to handle duplicate keys? There&amp;#8217;s no standard
-behavior. It&amp;#8217;s up to applications. And looking at what is done in
-the wild, there&amp;#8217;s no de facto standard either. While some ignore
-duplicate keys (keeping the first or the last they find), others
-require duplicate keys to end with &lt;code&gt;[]&lt;/code&gt; to automatically
-put the values in a list, or even worse, languages like PHP even
-allow you to do things like &lt;code&gt;key[something][other]&lt;/code&gt; and
-create a deep structure for it. Finally some allow any key to have
-duplicates and just gives you lists of key/values.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Cowboy so far had functions to retrieve query string values one
-value at a time, and if there were duplicates it would return the
-first it finds. It also has a function returning the entire list
-with all duplicates, allowing you to filter it to get all of them,
-and another function that returns the raw query string.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;What are duplicates used for? Not that many things actually.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;One use of duplicate keys is with HTML forms. It is common practice
-to give all related checkboxes the same name so you get a list of
-what&amp;#8217;s been checked. When nothing is checked, nothing is sent at all,
-the key is not in the list.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Another use of duplicate keys is when generating forms. A good
-example of that would be a form that allows uploading any number
-of files. When you add a file, client-side code adds another field
-to the form. Repeat up to a certain limit.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;And that&amp;#8217;s about it. Of note is that HTML radio elements share
-the same name too, but only one key/value is sent, so they are not
-relevant here.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Normally this would be the part where I tell you how we solve
-this elegantly. But I had doubts. Why? Because there&amp;#8217;s no good
-solutions to solving only this particular problem.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;I then stopped thinking about duplicate keys for a minute and
-started to think about the larger problem.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Query strings are input data. They take a particular form,
-and may be sent as part of the URI or as part of the request
-body. We have other kinds of input data. We have headers and
-cookies and the request body in various forms. We also have
-path segments in URIs.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;What do you do with input data? Well you use it to do
-something. But there is one thing that you almost always do
-(and if you don&amp;#8217;t, you really should): you validate it and
-you map it into Erlang terms.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Cowboy left the user take care of validation and conversion
-into Erlang terms so far. Rather, it left the user take care
-of it everywhere except one place. Guess where? That&amp;#8217;s right,
-bindings.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;If you define routes with bindings then you have the option
-to provide constraints. Constraints can be used to do two things:
-validate the data and convert it in a more appropriate term. For
-example if you use the &lt;code&gt;int&lt;/code&gt; constraint, Cowboy will
-make sure the binding is an integer, and will replace the value
-with the integer representation so that you can use it directly.
-In this particular case it not only routes the URI, but also
-validates and converts the bindings directly.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;This is very relevant in the case of our duplicate keys,
-because if we have a list with duplicates of a key, chances
-are we want to convert that into a list of Erlang terms, and
-also make sure that all the elements in this list are expected.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The answer to this particular problem is simple. We need a
-function that will parse the query string and apply constraints.
-But this is not all, there is one other problem to be solved.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The other problem is that for the user some keys are mandatory
-and some are optional. Optional keys include the ones that
-correspond to HTML checkboxes: if the key for one or more
-checkbox is missing from the query string, we still want to
-have an empty list in our map so we can easily match. Matching
-maps is great, but not so much when values might be missing,
-so we have to normalize this data a little.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;This problem is solved by allowing a default value. If the
-key is missing and a default exists, set it. If no default
-exists, then the key was mandatory and we want to crash.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;I therefore make a proposal for changing the query string
-interface to three functions.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The first function already exists, it is &lt;code&gt;cowboy_req:qs(Req)&lt;/code&gt;
-and it returns only the query string binary. No more Req returned.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The second function is a renaming of &lt;code&gt;cowboy_req:qs_vals(Req)&lt;/code&gt;
-to something more explicit: &lt;code&gt;cowboy_req:parse_qs(Req)&lt;/code&gt;.
-The new name implies that a parsing operation is done. It was implicit
-and cached before. It will be explicit and not cached anymore now.
-Again, no more Req returned.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The third function is the one I mentioned above. I think
-the interface &lt;code&gt;cowboy_req:match_qs(Req, Fields)&lt;/code&gt; is
-most appropriate. It returns a normalized map that is the same
-regardless of optional fields being provided with the request,
-allowing for easy matching. It crashes if something went wrong.
-Still no Req returned.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;I feel that this three function interface provides everything
-one would need to comfortably write applications. You can get
-low level and get the query string directly; you can get a list
-of key/value binaries without any additional processing and do it
-on your own; or you can get a processed map that contains Erlang
-terms ready to be used.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;I strongly believe that by democratizing the constraints to
-more than just bindings, but also to query string, cookies and
-other key/values in Cowboy, we can allow the developer to quickly
-and easily go from HTTP request to Erlang function calls. The
-constraints are reusable functions that can serve as guards
-against unwanted data, providing convenience in the process.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Your handlers will not look like an endless series of calls
-to get and convert the input data, they will instead be just
-one call at the beginning followed by the actual application
-logic, thanks to constraints and maps.&lt;/p&gt;&lt;/div&gt;

-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;(Don&amp;#8217;t look too closely at the structure yet.)&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;As you can see in the above snippet, it becomes really easy
-to go from query string to values. You can also use the map
-directly as it is guaranteed to only contain the keys you
-specified, any extra key is not returned.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;This would I believe be a huge step up as we can now
-focus on writing applications instead of translating HTTP
-calls. Cowboy can now take care of it.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;And to conclude, this also solves our duplicate keys
-dilemma, as they now automatically become a list of binaries,
-and this list is then checked against constraints that
-will fail if they were not expecting a list. And in the
-example above, it even converts the values to atoms for
-easier manipulation.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;As usual, feedback is more than welcome, and I apologize
-for the rocky structure of this post as it contains all the
-thoughts that went into this rather than just the conclusion.&lt;/p&gt;&lt;/div&gt;

+      <description>Now that Cowboy 1.0 is out, I can spend some of my time thinking about Cowboy 2.0 that will be released soon after Erlang/OTP 18.0. This entry discusses the proposed changes to query string handling in Cowboy.
+ Cowboy 2.0 will respond to user wishes by simplifying the interface of the cowboy_req module. Users want two things: less juggling with the Req variable, and more maps. Maps is the only dynamic key/value data structure in Erlang that we can match directly to extract values, allowing users to greatly simplify their code as they don&amp;#8217;t need to call functions to do everything anymore.</description>

       <guid>https://ninenines.eu/articles/january-2014-status/</guid>
-      <description>&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;I will now be regularly writing posts about project status, plans
-and hopes for the future.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Before that though, there&amp;#8217;s one important news to share.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Until a year ago all development was financed through consulting
-and development services. This worked alright but too much time was
-spent doing things that didn&amp;#8217;t benefit the open source projects.
-And that didn&amp;#8217;t make me happy at all. Because I like being happy
-I stopped that for the most part and spent the year figuring things
-out, experimenting and discussing with people about it.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;What makes me happy is answering these &#34;what if&#34; questions.
-Ranch and Cowboy are a direct product of that, as they originate
-from the &#34;what if we could have a server running different protocols
-on different ports but all part of the same application?&#34;; Erlang.mk
-is a bit different: &#34;this works great for me, what if it could
-become the standard solution for building Erlang applications?&#34;.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;When I successfully answer the question, this becomes a project
-that may end up largely benefiting the Erlang community. I love
-Erlang and I love enabling people to build awesome products based
-on my projects. It&amp;#8217;s a lot more rewarding than activities like
-consulting where you only help one company at a time. And it&amp;#8217;s
-also a much better use of my time as this has a bigger impact on
-the community.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The hard part is to figure out how to be able to spend 100%
-of the time on projects that you basically give away for free,
-and still be able to afford living.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The immediate solution was getting work sponsored by the
-&lt;a href=&#34;http://www.leofs.org/&#34;&gt;LeoFS project&lt;/a&gt;. LeoFS is a great
-distributed file storage that I can only recommend to anyone who
-needs to store files or large pieces of data. The sponsorship
-works pretty great, and spurred development of the SPDY code in
-Cowboy amongst other things, plus a couple upcoming projects
-done more recently and getting a final touch before release.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;It turns out sponsoring works great. So I&amp;#8217;m thinking of
-expanding on it and hopefully get enough sponsoring for fulltime
-open source development. So I figured out a few things that
-can give incentive to companies willing to sponsor.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Sponsors can &lt;em&gt;request that a particular version of Cowboy
-be maintained indefinitely&lt;/em&gt; (as long as they&amp;#8217;re sponsoring).
-This means fixes will be backported. This doesn&amp;#8217;t include
-features although I can take requests depending on feasability.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Sponsors can &lt;em&gt;have a direct, private line of communication&lt;/em&gt;,
-useful when they need help debugging or optimizing their product.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Sponsors can &lt;em&gt;get their name associated with one of the
-project&lt;/em&gt; and get a good standing in the community thanks
-to this. They would be featured in the README of the project
-which is viewed by hundreds of developers daily.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Sponsors can &lt;em&gt;be listed on this website&lt;/em&gt;. I will modify
-the front page when we get a few more sponsors, they will be
-featured below the carousel of projects.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Please &lt;a href=&#34;mailto:[email protected]&#34;&gt;contact us&lt;/a&gt; if
-you are interested in sponsoring, and say how much you are willing
-to sponsor. The goal here is only to have enough money to make a
-living and attend a few conferences. There&amp;#8217;s an upper limit in the
-amount needed per year, so the more sponsors there are the cheaper
-it becomes to everyone.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The upper limit stems from the new legal entity that will replace
-the current Nine Nines. This is mostly to lower the legal costs and
-simplify the administrative stuff and allow me to dedicate all my
-time on what&amp;#8217;s important. From your point of view it&amp;#8217;s business as
-usual.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Now on to project statuses and future works.&lt;/p&gt;&lt;/div&gt;

-&lt;h2 id=&#34;_cowboy&#34;&gt;Cowboy&lt;/h2&gt;
-&lt;div class=&#34;sectionbody&#34;&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Cowboy is getting ready for a 1.0 release. Once multipart support
-is in, all that&amp;#8217;s left is finishing the guide, improving tests and
-finishing moving code to the cowlib project. I hope everything will
-be ready around the time R17B is released.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;I already dream of some API breaking changes after 1.0, which
-would essentially become 2.0 when they&amp;#8217;re done. An extensive survey
-will be setup after the 1.0 release to get more information on what
-people like and don&amp;#8217;t like about the API.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;And of course, when clients start implementing HTTP/2.0 then we
-will too.&lt;/p&gt;&lt;/div&gt;

-&lt;h2 id=&#34;_ranch&#34;&gt;Ranch&lt;/h2&gt;
-&lt;div class=&#34;sectionbody&#34;&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Ranch is also getting close to 1.0. I am currently writing a
-test suite for upgrades. After that I also would like to write
-a chaos_monkey test suite and add a getting started chapter to the
-guide.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Ranch is pretty solid otherwise, it&amp;#8217;s hard to foresee new
-features at this point.&lt;/p&gt;&lt;/div&gt;
-&lt;/div&gt;
-&lt;/div&gt;
-&lt;div class=&#34;sect1&#34;&gt;
-&lt;h2 id=&#34;_erlang_mk&#34;&gt;Erlang.mk&lt;/h2&gt;
-&lt;div class=&#34;sectionbody&#34;&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;I didn&amp;#8217;t expect this project to become popular. Glad it did though.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Windows support is planned, but will require GNU Make 4.
-Thankfully, it&amp;#8217;s available at least through cygwin. Make,
-Git and Erlang will be the only required dependencies
-because the rest of the external calls will be converted to
-using Guile, a Scheme included since GNU Make 4. So it is
-Guile that will download the needed files, magically fill
-the list of modules in the &lt;em&gt;.app&lt;/em&gt; file and so on, allowing
-us to provide a truly cross-platform solution without
-losing on the performance we benefit from using Make.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Also note that it is possible to check whether Guile
-is available so we will be able to fallback to the current
-code for older systems.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;I am also thinking about adding an extra column to the package
-index, indicating the preferred tag or commit number to be used.
-This would allow us to skip the individual &lt;code&gt;dep&lt;/code&gt; lines

-And committing that file to your project would be the only thing
-needed to lock the dependencies. Of course if a &lt;code&gt;dep&lt;/code&gt;

-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;This is the two-parts project requested by the LeoFS team.
-This is essentially a &#34;distributed bigwig&#34;. I am hoping to
-have a prototype up in a few days.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Alien is the part that allows writing and enabling probes
-in your nodes. Probes send events which may get filtered before
-being forwarded to their destination. The events may be sent
-to a local process, a remote process, over UDP, TCP or SSL.
-Events may also be received by a process called a relay, which
-may be used to group or aggregate data before it is being sent
-over the network, reducing the footprint overall.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Shaman is the UI for it. It will ultimately be able to display
-any event as long as it&amp;#8217;s configured to do so. Events may be logs,
-numeric values displayed on graphs updated in real time, lists of
-items like processes and so on.&lt;/p&gt;&lt;/div&gt;
-&lt;/div&gt;
-&lt;/div&gt;

-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;That&amp;#8217;s it for today! There will be another status update once
-Shaman is out. But for now I have to focus on it.&lt;/p&gt;&lt;/div&gt;
-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;As always, please send feedback on the projects, this post,

+      <description>I will now be regularly writing posts about project status, plans and hopes for the future.
+ Before that though, there&amp;#8217;s one important news to share.
+ Until a year ago all development was financed through consulting and development services. This worked alright but too much time was spent doing things that didn&amp;#8217;t benefit the open source projects. And that didn&amp;#8217;t make me happy at all. Because I like being happy I stopped that for the most part and spent the year figuring things out, experimenting and discussing with people about it.</description>

+      <description>Building OTP releases has always been a difficult task. Tools like Reltool or Rebar have made this simpler, but it&amp;#8217;s no panacea. This article will show you an alternative and hopefully much simpler solution.
+ There is two steps to building a release. First you need to build the various OTP applications you want to include in the release. Once done, you need to create the release itself, by including the Erlang runtime system alongside the applications, a boot script to start the node and all its applications, and some configuration files.</description>

+      <guid>https://ninenines.eu/articles/xerl-0.5-intermediate-module/</guid>
+      <description>Today we will start the work on the intermediate module that will be used to run the code for the expressions found in our file&amp;#8217;s body, replacing our interpreter.
+ This is what we want to have when all the work is done:
+ xerl -&amp;gt; tokens -&amp;gt; AST -&amp;gt; intermediate -&amp;gt; cerl  Today we will perform this work only on the atomic integer expression however, so we will not build any module at the end.</description>

+      <guid>https://ninenines.eu/articles/xerl-0.4-expression-separator/</guid>
+      <description>As promised we are adding an expression separator this time. This will be short and easy.
+ In the tokenizer we only need to add a line recognizing the comma as a valid token.
+ , : {token, {&#39;,&#39;, TokenLine}}. Then we need to change the following lines in the parser:
+ exprs -&amp;gt; expr : [&#39;$1&#39;]. exprs -&amp;gt; expr exprs : [&#39;$1&#39; | &#39;$2&#39;]. And add a comma between the expressions on the second line:</description>

+      <description>I would like to share some experience and theories on Erlang scalability.
+ This will be in the form of a series of hints, which may or may not be accompanied with explanations as to why things are this way, or how they improve or reduce the scalability of a system. I will try to do my best to avoid giving falsehoods, even if that means a few things won&amp;#8217;t be explained.</description>

+      <guid>https://ninenines.eu/articles/xerl-0.3-atomic-expressions/</guid>
+      <description>We will be adding atomic integer expressions to our language. These look as follow in Erlang:
+ 42. And the result of this expression is of course 42.
+ We will be running this expression at compile time, since we don&amp;#8217;t have the means to run code at runtime yet. This will of course result in no module being compiled, but that&amp;#8217;s OK, it will allow us to discuss a few important things we&amp;#8217;ll have to plan for later on.</description>

+      <description>Everything is an expression.
+ This sentence carries profound meaning. We will invoke it many times over the course of these articles.
+ If everything is an expression, then the language shouldn&amp;#8217;t have any problem with me defining two modules in the same source file.
+ mod first_module begin end mod second_module begin end Likewise, it shouldn&amp;#8217;t have any problem with me defining a module inside another module.
+ mod out_module begin mod in_module begin end end Of course, in the context of the Erlang VM, these two snippets are equivalent; there is nothing preventing you from calling the in_module module from any other module.</description>

+      <description>Let&amp;#8217;s build a programming language. I call it Xerl: eXtended ERLang. It&amp;#8217;ll be an occasion for us to learn a few things, especially me.
+ Unlike in Erlang, in this language, everything is an expression. This means that modules and functions are expression, and indeed that you can have more than one module per file.
+ We are just starting, so let&amp;#8217;s no go ahead of ourselves here. We&amp;#8217;ll begin with writing the code allowing us to compile an empty module.</description>

+      <description>Last week I was speaking at the London Erlang Factory Lite where I presented a live demonstration of building an FTP server using Ranch. As there was no slide, you should use this article as a reference instead.
+ The goal of this article is to showcase how to use Ranch for writing a network protocol implementation, how Ranch gets out of the way to let you write the code that matters, and the common techniques used when writing servers.</description>

+      <description>Everyone knows Tic Tac Toe, right?
+ Players choose either to be the Xs or the Os, then place their symbol on a 3x3 board one after another, trying to create a line of 3 of them.
+ Writing an algorithm to check for victory sounds easy, right? It&amp;#8217;s easily tested, considering there&amp;#8217;s only 8 possible winning rows (3 horizontal, 3 vertical and 2 diagonal).
+ In Erlang though, you probably wouldn&amp;#8217;t want an algorithm.</description>
