say have several registered users in website. users saved on single table 'users' assigns unique id each 1 of them. i want allow users track expenses, miles driven, temperature, etc. i can't sure each user enter value all trackable variables when login -- example of happen be: 'example data' user date amount miles temp etc 1 3/1/2010 $10.00 5 54 2 3/1/2010 $20.00 15 1 3/12/2010 5 55 1 3/15/2010 $10.00 25 51 3 3/20/2010 45 3 4/12/2010 $20.00 10 54 what best way set tables situation? should create table exclusive each user when register?

i cannot shell_exec ( 'svn /var/www/mydirectory' ) work. reason nothing happens. tempted think permission issue, not sure. can execute no problem: shell_exec ( 'svn help' ) this because of file-permission issue. in php configurations, /var/www/* not writable php user. svn /var/www/... tries write directory, while svn help not. /var/www/ not writable php user security precaution. making writable makes site more vulnerable because if bug found in php scripts, attacker more capable of taking complete control on server. (because able write own php code on server) if /var/www/mydirectory not contain php code needs execute, should safe chmod -x+w mydirectory/ . if mydirectory contains php code need execute, , you've assessed there not more secure way of doing it, use chmod +w mydirectory/ . note, recommend making cron job or using other way of running svn up operation different user, , leaving read-only php process.

i've inherited asp.net web app, , coming speed on being dba well. before break anything, if add new column table, there chance break existing page crud operations? new column not, of course, part of existing operations , grid controls, , if allow contain null (so inserts don't require value input), ok? i realize deleting column break things. adding nullable column seem harmless enough. (i think). but want check! thanks well, depends on how app written. if, example, code uses column numbers instead of names it's things break, if add columns in between ones exist. hopefully app has enough unit tests try out confidence. if not, maybe adding unit tests should first priority.

according answers this question here , reason why i'm not seeing errors work in flash builder fb "optimizing" them out because aren't referenced @ point in code execution. there option force flash builder compile files regardless of whether they're used in software? make development process lot more intuitive. the way reference class somewhere in code know is being compiled, such document class in .fla, or main.as file in pure as3 project. can simple declaring variable of given type, if no value ever assigned it. private var complieme:otherwiseunreferencedclass; // ^ cause class compiled.
