First, I apologize for such a novice question again, and if this has been answered elsewhere.
There are too many template engine，I really do not know how to choose！I seriously study this, but still at a loss.
I mainly want to know the advantages of mustache.js/handlebars.js? Compared with the JavaScript Micro-Templating
Please give examples to explain, thank you very much!
For a pretty well-rounded comparison see
http://engineering.linkedin.com/frontend/client-side-templating-throwdown-mustache-handlebars-dustjs-and-more
It includes a lot of considerations and a good 'in-the-field' approach.
Moreover, it's from LinkedIn so you can trust it's pretty thorough.
EDIT:
Only real omission is Hogan from Twitter, likely because it was (and still is) a new kid on the block . http://twitter.github.com/hogan.js/) Like Handlebars based on Mustache. Functionality is in between Mustache and Handlebars. Performance 5/5.
I use Hogan both on the client-side and with Nodejs on the server-side and it's really great working with it once you get the hang of it.

I'm using ScalaJS with Play. Many of the models I'd like to use on both JS and JVM platforms involve dates and times. Given the lack of a cross-platform date/time library, how are people approaching this?
Things I know about:
scalajs-java-time project (https://github.com/scala-js/scala-js-java-time) to port JDK8's java.time api to Scala.js. Unfortunately, it's far from complete and judging by the commit logs, seems to have stalled.
https://github.com/mdedetrich/soda-time is a port of JodaTime to Scala/Scala.js. But it's not ready for production use.
An old post at https://groups.google.com/forum/#!topic/scala-js/6JoJ7x-VxLA suggests storing milliseconds in shared code and then doing implicit conversions on each platform to either js.Date or JodaTime. But we really need a common interface, which this doesn't give.
Li Haoyi's excellent "Hands-on Scala.js" has a simple cross-platform library (http://www.lihaoyi.com/hands-on-scala-js/#ASimpleCross-BuiltLibrary) that could, in theory, be extended to come up with an API in /shared that delegates to JodaTime on the jvm and Momento on js -- but that sounds like a lot of work.
(added later) https://github.com/soc/scala-java-time is based on an implementation of java-time that was contributed to OpenJDK. The README claims that most stuff is working. Right now, this looks like the most promising approach for my needs.
Any advice from those who have gone before me? Right now the fourth options seems like my best bet (with the API limited to stuff I actually use). I'm hoping for something better.
I was in the same boat as you, and the best solution I came up with was cquiroz's scala-java-time library. From reading the comments to your question above, it appears you landed at the same place eventually!
I came here from a google search, and given how much better this solution is than the alternatives you mentions above, let's consider marking this question as resolved for future visitors.
At my office we currently use ZF1, and we're looking to use ZF2.
It takes us ages to put together simple websites because ZF just doesn't seem organised enough - it's almost a non-framework in my opinion.
Anyway, I was wondering if anyone's built a more 'standard' sort of framework on top, or skeleton application that is friendly to use and well documented - one that has all the kind of standard stuff you'd find in other more simple frameworks like CI/Cake/Symphony etc.
The reason I ask is because I don't think there's any way I can convince my boss that we should use something else, and also I think it would benefit the rest of the team hugely if the whole process could be simplified a bit.
Cheers,
John.
I wrote a blog post on this instead.. thought it might be more useful in that format :)

I want to learn Lift. Unfortunately, all documentation which I tried either obsolete, unreadable, incorrect or combination of the above. I tried the following:
Simlply Lift. Some things from the book I tried lead to errors.
Exploring Lift. The structure of book is very bad. It's hard to read and try out code in the wild at the same time.
Lift in Action. The same as the previous but you need to pay for it.
P.S. I've seen similar questions. Most of them were asked a long time ago. Did the situation improve from the time of that writings?
P.P.S. Are there any other type safe scala web frameworks (Don't offer Play 2.0. It's not typesafe. I don't see any reason to create it in Scala).
It is unfortunately true that the state of Lift documentation is uneven at best and there are huge gaping holes.
However, the Lift community is just full of awesomely helpful people.
My recommendation is not to play around, but rather to try and implement something. If you get stuck, ask specific, direct questions about what you're trying to do, how you're doing it and why it isn't working.
So far, though I would wish for better documentation, I've been able to get every answer that I needed either through Google or on the Lift mailing list - though I expect I might ask more questions here in the future.
The Lift documentation is not its strong point. The philosophy is more "try and ask if you have any problem". Here are a few tips:
Assembla
One ressource that is really useful is http://www.assembla.com/wiki/show/liftweb, there are a lots of examples so you can progressively learn how it works.
Mailing List
Otherwise you can always use the mailing list if you have specific questions even if in my opinion it is really hard to explore it fast in order to solve a problem which was already encountered. http://groups.google.com/group/liftweb
Stack Overflow
Finally, a small community is present on Stackoverflow so feel free to ask in here. This is a good way of looking for answers and creating documentation in the same time.
Source code
Don't hesitate to explore the source code and the scaladoc if you have specific questions/doubts about the behavior of a function, they are often short and even sometimes commented! http://scala-tools.org/mvnsites/liftweb-2.4-M4/#package
Have a look at the Lift Cookbook: http://cookbook.liftweb.net/
"Simlply Lift. Some things from the book I tried lead to errors."
What exact type of errors did you have? Have you tried to follow it with "Simply Lift" examples that you can download from GitHub
https://github.com/dpp/simply_lift?
Only errors I had were related to my lack of experience with SBT, but that's another story.
I have started with Lift mostly from that source (Simply Lift + examples) and in combination with its great community and Google (ChrisJamesC has listed the main links really nice) it was quite okay for me.
I would suggest you to work out all examples given in the "Simply Lift" tutorial or at least work them out unless you feel comfortable enough to jump right "in media res" and try something by yourself. That was the best way of learning Lift for me.
Also, whenever you got stuck somewhere and can't find solution on the web, your questions would be welcome and answered on the Lift Google Group (https://groups.google.com/forum/?fromgroups=#!forum/liftweb). David Pollak is very often right there to answer your questions directly so I have only words of praise for this framework's community and Lift's
creator.
P.S. Lift's documentation could be better organized, some stuff could be better explained for sure, but IMHO it was just too small a price I had to pay to enjoy such beautiful framework. Learning curve is steeper than with Play, especially in the beginning, but after I "survived" the very first week it was almost impossible for me to give up of all of its advantages and original concepts (Lift's "Seven Things") and switch to another framework.
As much as I love this forum for my programming related questions, I am finding little or no help here. I am working on designing a Receiver for WLAN and have have lot of queries and I am looking for a forum where I can ask someone who are working in the same area.
I would be glad if you could suggest me where I can post my questions.
Thanks
For basic receiver design, you may want to have a look at our sister site, electronics.stackexchange. Also, Signal, Image & Video Processing might be of help once it gets off the ground.
Also, when you're working in a specific field with which programmers in general are not very familiar, you have to explain your questions very well in terms that everybody understands. To give you an example:
In 802.11b, Barker Code is used for spreading.
is completely incomprehensible for me, and, sorry, I don't have the time to fire up Wikipedia and order textbooks from our library to teach myself the specifics of how WLANs work.
I've been evaluating a framework that on paper looks great. The problem is that the sample code is incomplete and of poor quality. The supplied reference implementations are for the most part not meant to be used (so they can be considered as sample code as well) and have only succeeded at confusing me.
I know that it's common for things to look better on paper, but my experience with the sample code is turning me away from further investigation.
Do you let poor code samples change your judgment of frameworks/libraries? So far my experience has been similar to the "resume effect": if someone doesn't put the effort into spell checking their resume, they probably won't get the job...
For me, it does. I tend to want to avoid libraries where the code samples are incomplete. If the library is open source, I will overlook it, since I can directly look at the code and see if the library's internals are reasonable, and I know that, if there is a problem someday, I could (if I had to) fix it.
If the library is commercial, and their samples and/or documentation is poor, I look elsewhere. I just see it as risk management - poor samples make me fear the quality of the library in general.
No matter how good something is on paper or in theory, it can still be crap when programmed.
I think this is a valid reason to turn away from and evaluate other libraries. As a potential user of a library a lack of documentation and/or bad code samples gives the impression that the library is not yet mature enough for use by third parties. In time it may well gain the missing pieces but until then I think its reasonable to look elsewhere.
I was recently evaluating the multitude of blogging applications that people have uploaded to github.com I quickly skipped ones that no documentation as they obviously weren't ready for others to use. The ones that remained at the end had a good README with info on how to get the app up and running as well as an online example of the code running.
Poor code samples combined with poor documentation will make me turn away from a library unless there is a compelling reason to use it. However, a library that has either good code samples or good documentation is usually worth using. (Assuming that the library itself otherwise meets my needs.)
If I can't find good examples (and/or documentation) illustrating how to use the library, I'm definitely less likely to use it - just as a practical matter, it'll be harder for me to figure out how. But I don't care what the code that implements the library itself looks like. I don't think I'd choose one library/framework over another just because the developers of the one have shown an ability to write cleaner code (which is what I understand the "resume effect" to mean).
Lack of documentation and examples makes me a whole lot less likely to use that particular library. It's not worth my time testing and trying to figure out how a black box works if there are alternate solutions to the problem out there.
Yes, definitely. Every library should come with a simple example using program and a CLI interface (for very simple libraries with <3 methods and <10 hooks, one example should suffice).
And why does your framework "look great" if it's so hard to use that even the original coders make mistakes using it?
It certainly matters to me. Evidence of sloppy/incomplete coding and poor communication decreases my confidence that the actual implementation code is stable and robust.
Myself yes, but there must be people out there who aren't turned off by this otherwise there are plenty of open source projects that would have died a long long time ago.
