@anastasia_s said in Why is Node.js so popular?: Hey, thanks for all the responses, very interesting. I've been looking into Node.js for some time and found some interesting facts. Did you know that Node.js is being used by NetFlix, SAP, GoDaddy, IBM and more? I found it. Also, are those salary rates correct? If so, I'd totally start learning Node. Please no links to promotional sites on first post, and definitely don't pretend that promotional sites are normal links to general references. Yes, NodeJS pays well, it's a good field to be in.

That's neat. More accessible is good.

What little text editing I do, I usually do it with vi.

You don't know JS free open source book series is probably one of the best resources too. It explains how JS works, other than explaining how to program it in a nice way. I think that if someone understand well how a programming language works, then he should know how to program it in the proper way, no?

Looks like Harvard has followed suit and is blindly following Stanford into moving their CS program closer and closer to just being relabeled software engineering.

@Lakshmana said in Book Reference for ReactJS: @scottalanmiller Ok Thank YOu .Its already suggested by thwr Whoops Well it looks like a good one.

Received a few emails from Mozilla myself, about Mozilla Thimble - sadly, only watched the videos so far, but, does look good so far.

OK this sounds kinda cool.

InfoWorld has an article about Microsoft's Chakra and ChakraCore efforts as well: http://www.infoworld.com/article/3024271/javascript/nodejs-welcomes-microsoft-chakra-javascript-engine.html

@Dashrender said: Do you think this will lead to an even higher infection rate than before? Yes, because it now does not even take any coding knowledge. The crypto is created for you. All the person now has to do is find a delivery mechanism.

gte and lte values create the "bounds" of the query. Adjust accordingly to change the date range. Value is "epoch time."

@coliver said: Wasn't there a project that ran Python on top of Python? Likely.

Here is an example: http://community.spiceworks.com/topic/1190263-java-script-inserting-an-image-into-a-pdf-form In this discussion, he titles the post "Java Script". But there is no Java Script, there is Java which is not a scripting language and there is JavaScript which is. So it would either be a Java program (lower case p) or a JavaScript script (lower case s.) The use of the upper case S in Script implies that he believes it to be a part of the name, but there is nothing with that name. He tags the thread "Java" which implies he truly means Java, but where did the word Script come from? Nothing in the topic provides a clue as to what he is doing. There is not any context to determine what language he is referring to. And given that he is unsure how to refer to them or that there could be confusion it is completely realistic that he does not mean either.

@Reid-Cooper said: @thecreativeone91 I thought that the HTML5 spec was going to have specific file and codec types specified. Was that dropped? No. it just provides a way to present the video. It's up to the browser to support the codec. H.264 is the most common, but even then there are differnt types as it's a GOP codec there's I frames and P frames. where I frames are key frames and P frames are rendered by the computer as inbetween frames at the time of playback using a lot more cpu. All I frames take less cpu usage but are much bigger in size.

I use RubyMine daily now and love it. JetBrains makes some of my favourite stuff.

Yes. Though I thought it was pretty straightforward. The videos are pretty good for free, but the full price of $29 seems optimistic.

Some more info on why io.js decided to fork Node.js.

Care to share?
