i in process of developing special-purpose network tool packet sniffing , decoding capabilities. looking languages designed assist in dissection/decoding of arbitrary packet formats. idealy, solution should based on open standards. there related questions on so, deal full lifecycle of packet sniffing (i don't care capture, there other libraries well). in general, i'm looking language , supporting framework declaritive definition of packet formats , corresponding run-time decoding. because problem can generalized non-network binary data, solution arbitrary binary streams in scope. little surprised no such standard exists in mature , robust state (at least find) - though there seem lot of interesting not-quite-right , almost-there projects (see below). perhaps speaks difficulty of problem, or maybe lack of demand. by way of example, i'm interested in technologies , ideas similar following (in no particular order): packet.net - job of converting binary packet repre...

my desktop qt app has large stylesheet applied. it's applied qapplication derived class using: this->applystylesheet(":/qss/default.qss"); it works qwidget objects define , use.

is there built in function following? $a[] = $b[0]['foo']; $a[] = $b[1]['foo']; $a[] = $b[2]['foo']; etc.. i realize can following: foreach($b $c) { $a[] = $c['foo']; } but curious if there built in array function this. thanks. in short: no. in long: maybe ;) because not "directly built-in" with php5.3 $a = array_map (function ($entry) { return $entry['foo']; }, $b); or before $a = array_map (create_function ('$entry', 'return $entry[\'foo\'];'), $b); at least second solution prefer foreach -loop ;)

there may situations compilation process takes more time program's run time. should 1 in circumstances? if consider cgi scripts may called hundreds or thousands of times every minute above problem may occur. how avoid these problems? can't skip compilation process. how deal such situations? if looking @ perl-based cgi scripts, consider using mod_perl or fastcgi , address exact issue (among others). a more generic way of doing same thing build sort of "server" application loads once , listen client connections. clients can small lightweight processes connect server , ask server perform whatever work needed.

i know reading single object across multiple threads safe in java, long object not written to. performance implications of doing instead of copying data per thread? do threads have wait others finish reading memory? or data implicitly copied (the reason of existence of volatile )? memory usage of entire jvm? , how differ when object being read older threads read it, instead of created in lifetime? if know object not change (e.g. immutable objects such string or integer) , have, therefore, avoided using of synchronization constructs ( synchronized , volatile ), reading object multiple threads not have impact on performance. threads access memory object stored in parallel. the jvm may choose, however, cache values locally in each thread performance reasons. use of volatile forbids behaviour - jvm have explicitly , atomically access volatile field each , every time.

i have found out creating 2 new websites under iis 7 single sign-on authentication doesn't work when run in different application pools. when move applications same pool can login on 1 of them , logged in on other one. when change application pool on 1 of them, don't logged in on second one. is there settings can set in machine.config file allow them share same cookie on application pools? ex. 1: proj1 (app pool .net 2) proj2 (app pool .net 2) = single sign-on works, sharing same auth cookie. ex. 2: proj1 (app pool .net 2) proj2 (app pool .net 4, integrated/classic) = single sign-on not work, not sharing same auth cookie. ex. 2: proj1 (app pool .net 4, integrated/classic) proj2 (app pool .net 4, integrated/classic) = single sign-on works, sharing same auth cookie. original post latest update @ bottom i have 2 projects, 1 asp.net webforms , other mvc 3 project. i followed guide, see @ bottom, , got working on computer. when upload server, ...

i have system allows person select form type want fill out drop down box. this, rest of fields particular form shown, user fills them out, , submits entry. form table: | form_id | age_enabled | profession_enabled | salary_enabled | name_enabled | this describes metadata of form system know how draw it. each _enabled column boolean true if form should include field filled out column. entry table: | entry_id | form_id | age | profession | salary | name | country | this stores submitted form. age, profession, etc stores actual value filled out in form (or null if didn't exist in form) users can add new forms system on fly. now main question: add ability user designing new form able include list of possible values attribute (e.g. profession drop down list of 20 professions instead of text box when filling out form). can't store global list of possible values each column because each form have different list of values pick from. the solution can come include se...

i have 2 columns in row: min_value , max_value . there way select like: select rand(`min_v`, `max_v`) `foo` [..] i realize rand different thing; closest came (with help) (rand() * (max-min))+min , though produce float number, i'd need round() , wrong. unless can suggest alternative (which useful), go php way. actually, round((rand() * (max-min))+min) best way in mysql you'd like. best way in actionscript, javascript, , python. honestly, prefer php way because more convenient. because don't know how many rows you'll returning, can't advise whether better use php or mysql this, if you're dealing large number of values better off using mysql. addendum so, there question whether better in php or mysql. instead of getting debate on principles, ran following: <pre><?php $c = mysql_connect('localhost', 'root', ''); if(!$c) die('!'); echo mysql_select_db('test', $c)?'connection':...

let's have entity in 3d space , know position vector (x, y, z) , velocity vector (so orientation in space). starting known point want reach known point b in 2 steps: a) turn, following circular path known radius r, until point c b) go straight point c final point b. speed (scalar value) not important. velocity (vector) known, guess should define plane on circle resides, being tangent it, line between , b... i want know how find coordinates (x, y, z) c , velocity vector of entity being there. update: see working demo! if understand correctly, situation (in plane containing a, b , v ) shown in diagram below. points , b given, vector v , distance r . want find point c. well, let vector w = (−v̂ y , v̂ x ) unit vector perpendicular v . o = + r w . now, |c − o| = r , (c − b)·(c − o) = 0 (where · dot product). combine these quadratic equation, can solve find 2 possible positions c. pick 1 right sign (c − b)×(c − o). (there's second choice centre o...

how set binary registry value (reg_binary) powershell? background: i need change properties of asp.net state service using powershell script. unfortunately, built-in powershell cmdlet set-service lets modify service description, startup type, display name, , status. need modify subsequent failures property found on recovery tab (when viewing service's properties). found value stored in registry reg_binary value. an export of value looks this: [hkey_local_machine\system\controlset001\services\aspnet_state] "failureactions"=hex:50,33,01,00,00,00,00,00,00,00,00,00,03,00,00,00,0e,00,00,\ 00,01,00,00,00,00,00,00,00,01,00,00,00,00,00,00,00,01,00,00,00,00,00,00,00 in powershell there set-itemproperty cmdlet can set registry value values. string or dword value, can pass string or int. know hex value in array change, can't figure out how set binary value. the following line gives example how create one new-itemproperty -path . -name test -property...

can please provide source on how write generic instead of trigger insert tables in database. want run stored procedure create instead of insert triggers tables in db . without understanding why want instead of trigger on every single table, , else plan in resulting code aside insert supplied values base table (just have happened if there no instead of trigger @ all), here came with. you'll note drops trigger if exists, can run multiple times in same database without "already exists" errors. ignores identity, rowguidcol, computed columns, , timestamp/rowversion columns. @ end show how can inspect, instead of execute (which commented out) output script (up 8k), , cast xml if want see more (up 64k). no guarantees can return whole thing in ssms depending on how many tables/columns there are. if want check and/or run manually may want create table stores value - can pull out app or have you. if want execute automatically can follow yuck's point - save stored p...
