• What javascript templating engine do you recommend?

  - by flybywire

  Do you have experience with a Javascript templating engine, one that is stable, easy to use and has good performance? I need to do apply the same template many times for different data. I prefer to download the template itself once (and have it cached) rather than processing the template on the server. Also, this way the template itself would be a static resource more easily cached in the server side too.

  - by Mike Gates

  I have an Excel 95 workbook, and I need to convert it into a format that is at least Excel 97, although preferably Excel 2003. I don't want to use office automation as this has all kinds of issues. Is there any way to do this in a .Net managed way?

• Better to use an OR or an AND when checking for NULLs in C if statements?

  - by Crazy Chenz

  Came across a line in OpenSSL that made me do a double take... if (!*pos) return NULL; if (!*pos || ((*pos)->flags == FLAGS)) return blah; Is there a (performance/security/concurrecy) difference in doing that instead of: if (!*pos) return NULL; if (*pos && ((*pos)->flags == FLAGS)) return blah; Thanks, Chenz

• Target Framework Mismatch

  - by Si Keep

  When adding a reference to a project I sometimes see the message... "The Target Framework version for the project is higher than the current project Target Framework version. Would you like to add this reference to your project anyway?" I understand what the message is indicating but can anyone explain what issues might arise from saying 'Yes'?

• Is it safe to modify CCK tables by hand?

  - by LanguaFlash

  I'm not intimately familiar with CCK but I have a one-time custom setup and know that I could get some performance gains if I created indexes and changed the field type and length of some of the fields in my CCK table. Is it save to modify this table at all or will I end up destroying something in the process? Thanks

• where should I do the calculating stuff,PHP or Mysql?

  - by SpawnCxy

  I've been doing a lot of calculating stuff nowadays.Usually I prefer to do this job in PHP rather than Mysql though I know PHP is not good at this cuz I thought mysql may be worse.But I found some performance problem :some pages were loaded so slowly that 30 seconds' timelimit is not enough for them!So I wonder which is the better practice to do the calculations,and any princles for that?Suggestions would be appreciated.

• Is it a good practice to always use smart pointers ?

  - by Dony Borris

  Hi, I find smart pointers to be a lot more comfortable than raw pointers. So is it a good idea to always use smart pointers? ( Please note that I am from Java background and hence don't much like the idea of explicit memory management. So unless there are some serious performance issues with smart pointers, I'd like to stick with them. ) Any advice would be greatly appreciated. Thanks.

• Using Int32 or what you need

  - by Sir Psycho

  Should you use Int32 in places where you know the value is not going to be higher than 32,767? I'd like to keep memory down, hoever, using casts everywhere just to perform simple arithmetic is getting annoying. short a = 1; short result = a + 1; // Error short result = (short)(a + 1); // works but looks ugly when does lots of times What would be better for overall application performance?

• WPF Label vs TextBlock in Border ?

  - by PaN1C_Showt1Me

  If you know that you have to show tens of texts with a border, would you decide for a Label (which is much complex and resources consuming) or a TextBlock in a Border? . The performance aspect is the one interesting for me now. Thank you !

• Is there any small linux distribution which comes with a complete C devleopment environment

  - by hits_lucky

  Hi, I have installed "Damn Small Linux" on my home computer for doing C development in unix. But the distribution doesn't by default come with the C development environment and I am facing some issues when trying to install the gcc. Is there any other small Linux distribution which by default has the required packages for the C development. And also I don't want additional software which takes up lot of space but still would like to have the graphical environment. Thanks

  - by kalak451

  I am having some low level issues with IntelliJ on my mac, I really want to just zero everything out and start over. But even after removing the application and re-installing it, IntelliJ still remembers things like what the last project was, what licensing key to use etc. Where is this information stored? And what is the best way to clear it out?

• What the best multi-thread application debugger for C++ apps.

  - by Coredumped

  I'm looking for a good multi-thread-aware debugger, capable of showing performance charts of application threads on Linux, don't know if such a thing exists, perhaps as a Eclipse plugin. The idea would be to track per thread memory allocation a CPU usage as well as being able to interrupt a thread and examine its stack trace, local vars, etc. It does not have to be an eclipse plugin or a free tool, do any of you have heard of something similar?

• Parent reference in automapped component

  In Fluent NHibernate, given an automapped component, is there a convention for setting up a parent reference back to the "holder" of the component? By having for example a property named Parent or something like that? I can't seem to find any information about how to do it or issues about it.

• Any Javascript optimization benchmarks?

  - by int3

  I watched Nicholas Zakas' talk, Speed up your Javascript, with some interest. I liked how he benchmarked the various performance improvements created by various optimization techniques, e.g. reducing calls to deeply nested objects, changing loops to count down instead of up, etc. I would like to run these benchmarks myself though, to see exactly how our current browsers are faring. I guess it wouldn't be too difficult to cook up some timed loops, but I'd like to know if there are any existing implementations out there.

• Filter to values in collection in one query

  - by dotnetdev

  Hi, I have the following LINQ query: List<string> Types = (List<string>) Directory.GetFiles(@"C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727") Where(x => System.IO.Path.GetFileNameWithoutExtension(x).Contains("Microsoft")) .ToList<string>(); How could I modify this so it can only get the values stored in a collection, without writing another LINQ query (which I assume will impact performance?)? Thanks

• Python `if x is not None` or `if not x is None`?

  - by orokusaki

  I've always thought of the if not x is None version to be more clear, but Google's style guide implies (based on this excerpt) that they use if x is not None. Is there any minor performance difference (I'm assuming not), and is there any case where one really doesn't fit (making the other a clear winner for my convention)?* *I'm referring to any singleton, rather than just None. ...to compare singletons like None. Use is or is not.
