but language-bashing for the sake of “I don’t like javascript” is no more helpful than Python people bashing Ruby. The fact is that Javascript as a language is extremely similar to Python in its syntax and construction (I often write my JS to PEP8 standards),
and though it’s not as readable as Python (what is?), there’s no reason JS code is inherently bad. Bad programmers write bad code. Bad frameworks encourage bad code. Node.js suffers from neither.<o:p></o:p></span></p>

<span style="font-size:10.0pt;font-family:"Tahoma","sans-serif"">Just so that everyone is aware, the lessc parser that is bundled in Horizon, while executable, is NOT a binary. It is, in fact, just a 140 line JS file, you can see the code here: <a href="https://review.openstack.org/#/c/7367/4/bin/less/lessc" target="_blank">https://review.openstack.org/#/c/7367/4/bin/less/lessc</a><o:p></o:p></span></li><li class="MsoNormal" style="color:black;mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l2 level1 lfo1">
<span style="font-size:8.0pt;font-family:"Tahoma","sans-serif"">The reason I have bundled it within the Horizon code, as Gabriel mentioned, is to assuage any version mismatches or install issues with LESS itself that may arise from having yet another dependency
on top of NodeJS that needs manual steps to install. Also, the LESS package that exists for Ubuntu is a year out of date, and other distributions do not even have packages for it. I would love if we could rely on the OS' packages to assuage this dependency,
but we cannot, so this is the simplest and best-working solution I could think of. It will be no more difficult to maintain than jQuery, or Bootstrap, in the Horizon code-base...<o:p></o:p></span></li><li class="MsoNormal" style="color:black;mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l2 level1 lfo1">
<span style="font-size:8.0pt;font-family:"Tahoma","sans-serif"">As for distribution support, Node can be installed on just about anything, see here: <a href="https://github.com/joyent/node/wiki/Installing-Node.js-via-package-manager" target="_blank">https://github.com/joyent/node/wiki/Installing-Node.js-via-package-manager</a><o:p></o:p></span></li><li class="MsoNormal" style="color:black;mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l2 level1 lfo1">
<span style="font-size:8.0pt;font-family:"Tahoma","sans-serif"">As to the concerns about "it not being Python" or "JavaScript has been abused." Well, all I can say to that is no, it is not Python, and yes, some developers write terrible and abusive code with
JavaScript. I'm sure I could find horrid/abusive Python somewhere as well, but doing so would not preclude our reasons to use it in OpenStack. Misuse of a tool is not a reason to fear the tool itself, if that were so none of us would use any language, ever.
Not to mention, we already use a ton of JS in Horizon... I'm not introducing JavaScript to Horizon for the first time or anything here.<o:p></o:p></span></li></ul>

even listed as a feature anywhere. So maybe my part in this topic is pointless. I'll be silent from now :)<br>

I don't want to be rude, but fast research about point *3c* and sockets<br>

How mature are those projects? I don't know. I'm not an expert in<br>
python. I'm just trying to find alternatives to Node.js if almost<br>
everything is in python. I'm just testing Openstack and right now I'm<br>
trying to add something to nova, but I really like horizon and if it's<br>
possible, I'd like to avoid node.js. I'm not a fan of this technology<br>
even if it's popular and fast, because I just have some doubts about<br>
Javascript and its maintainability.<o:p></o:p></span></p>

Hi Simon,<br>
<br>
<a href="http://socket.io" target="_blank">socket.io</a> is a Javascript library :) 3 of the 4 projects you reference above use
<a href="http://socket.io" target="_blank">socket.io</a>.<br>
<br>
Best,<br>
