• html/css: set div bounding box to window height

  - by noamtm

  It looks like I'm missing something basic. I want a certain DIV to have the height of the window. The effect should be that there's never any need to scroll down. Do I have to use JavaScript? I was told that it's possible with css, but I can't find the relevant property - or I'm doing something wrong.

• Best Embedded SQL DB for write performance?

  - by max.minimus

  Has anybody done any benchmarking/evaluation of the popular open-source embedded SQL DBs for performance, particularly write performance? I've some 1:1 comparisons for sqlite, Firebird Embedded, Derby and HSQLDB (others I am missing?) but no across the board comparisons... Also, I'd be interested in the overall developer experience for any of these (for a Java app).

• How do I bit shift a long by more than 32 bits?

  - by mach7

  It seems like I should be able to perform bit shift in C/C++ by more than 32 bits provided the left operand of the shift is a long. But this doesn't seem to work, at least with the g++ compiler. Example: unsigned long A = (1L << 37) gives A = 0 which isn't what I want. Am I missing something or is this just not possible? -J

• If the n-body problem is chaotic, why isn't it used as a RNG?

  - by David Titarenco

  I'm probably missing something pretty basic here, but if the n-body problem yields chaotic results (except in specific highly-symmetric conditions), couldn't it be used as a "true" random number generator (with initial pseudo-random seeds for masses and velocities) given its non-deterministic nature?

• Regular expression to match non-negative integers in PHP?

  - by kavoir.com

  I seem to get it to work with the following regexp by preg_match(): @^(?:[1-9][0-9]*)|0$@ Yet it's weird that it matches '-0', considering there are no '-' allowed at all in the regexp. Why? What's more weird is that if you switch the parts divided by |: @^0|(?:[1-9][0-9]*)$@ It matches all negative integers such as '-2' and '-10', etc. What am I missing here? Any better regexp for non-negative integer?

• What's the difference between text and html datatypes when using jQuery's ajax()

  - by user169867

  What does jQuery do differently when you specify the datatype as html as opposed to text. I haven't seen a difference but there must be some subtleties I'm missing. If I wish to return a portion of an html page as a string does it matter which I use?

• Problem with URI matcher in Android.

  - by Lunchbox

  I have an authority string defined as such: public final static String AUTHORITY = "dsndata.sds2mobile.jobprovider"; Followed by an edition to the UriMatcher: uriMatcher.addURI(JobMetaData.AUTHORITY, "/JobNames/*", JOBNAME_SINGLE_URI); The uri that gets passed to the switch is: content://dsndata.sds2mobile.jobprovider/JobNames/test This falls through the switch and hits the default (which throws an IllegalArgumentException). Am I missing something? I've searched and can't find anything that would account for the mismatch.

• Logging data with scribe

  - by lukatmyshu

  None of the scribe examples I've seen actually mention the best way to take logs/logfiles and send them to scribe. I could configure a logrotate script that has a postrotate section that "cats" the rotated file to scribe (but then I get minutes latency at best). The other option is to keep a "tail -f= | my_scribe_sender" and hope that the process never gets killed. However then you really can't guarantee that you're not missing/duplicating data.

• Use the right tool for the job: embedded programming

  - by EmbeddedProg

  I'm interested in programming languages well suited for embedded programming. In particular: Is it possible to program embedded systems in C++? Or is it better to use pure C? Or is C++ OK only if some features of the language (e.g. RTTI, exceptions and templates) are excluded? What about Java in this domain? Thanks.

• RESTful API: How to model 'request new password'?

  - by Jan P.

  I am designing a RESTful API for a booking application and was quite happy to see I could map all details of the application to the 4 HTTP methods. /users - GET, POST /users/({id}|myself) - GET, POST, PUT, DELETE /users/({id}|myself)/bookings - GET, POST /users/({id}|myself)/bookings/{id} - GET, POST, PUT, DELETE Example: Updating my own user uses a PUT to /users/myself. But now I found out that one thing is missing: The possibility to request a new password if I forgot my old one. Any idea how I could add this?
