is possible obtain raw logs google analytic? there tool can generate raw logs ga? no can't raw logs, there's nothing stopping getting exact same data logged own web server logs. have @ urchin code , borrow that, changing following 2 lines point web server instead. var _ugifpath2="http://www.google-analytics.com/__utm.gif"; if (_udl.protocol=="https:") _ugifpath2="https://ssl.google-analytics.com/__utm.gif"; you'll want create __utm.gif file don't show in logs 404s. obviously you'll need parse variables out of hits web server logs. log line in apache looks this. you'll have lots of "fun" parsing out various stuff want that, google analytics gets basic javascript tagging comes in this. 127.0.0.1 - - [02/oct/2008:10:17:18 +1000] "get /__utm.gif?utmwv=1.3&utmn=172543292&utmcs=iso-8859-1&utmsr=1280x1024&utmsc=32-bit&utmul=en-us&utmje=1&utmfl=9.0%20%20r124&utmdt=my%2...

the interface segregation principle (isp) says many client specific interfaces better 1 general purpose interface. why important? isp states that: clients should not forced depend on methods not use. isp relates important characteristics - cohesion , coupling . ideally components must highly tailored. improves code robustness , maintainability. enforcing isp gives following bonuses: high cohesion - better understandability, robustness low coupling - better maintainability, high resistance changes if want learn more software design principles, copy of agile software development, principles, patterns, , practices book.

in c# (or vb .net), compiler make attempts optimize property accesses? eg., public viewclass view { { ... computed here .... } } if (view != null) view.something = somethingelse; i imagine if compiler somehow detect view remains constant between 2 accesses, can refrain computing value twice. these kind of optimizations performed? i understand if view has intensive computations, should refactored function ( getview() ). in particular case, view involves climbing visual tree looking element of particular type. related: references on workings of (microsoft) c# compiler? not in general, no. steven mentioned there numerous factors consider regarding multithreading, if computing might change, you're correct should refactored away property. if won't change, should lazy-load (check if private member null, if calculate, return value). if won't change , depends on parameter, can use dictionary or hashtable cac...

i generating textblock in c# , want add tooptip displays image , text. how can without xaml? use code this:- textblock txt = new textblock(); txt.text = "hello world"; tooltipservice.settooltip(txt, "some content"); note can replace "some content" uielement containing pretty content wish.

how key of current element in foreach loop in c#? for example: php foreach ($array $key => $value) { echo("$value assigned key: $key"); } what i'm trying in c#: int[] values = { 5, 14, 29, 49, 99, 150, 999 }; foreach (int val in values) { if(search <= val && !stop) { // set key variable } } grauenwolf's way straightforward , performant way of doing array: either use loop or create temp variable increment on each pass. which of course this: int[] values = { 5, 14, 29, 49, 99, 150, 999 }; (int key = 0; key < values.length; ++key) if (search <= values[key] && !stop) { // set key variable } with .net 3.5 can take more functional approach well, little more verbose @ site, , rely on couple support functions visiting elements in ienumerable. overkill if need for, handy if tend lot of collection processing.

does java have built-in way escape arbitrary text can included in regular expression? example, if users enter "$5", i'd match rather "5" after end of input. since java 1.5, yes : pattern.quote("$5");

is there way change appearance of icon (ie. contrast / luminosity) when hover cursor, without requiring second image file (or without requiring hidden portion of image)? here's information image opacity , transparency css . so make image opacity 50%, you'd this: <img src="image.png" style="opacity: 0.5; filter: alpha(opacity=50)" /> the opacity: part how firefox it, , it's value between 0.0 , 1.0. filter: how ie it, , it's value 0 100.

i had idea mulling on colleagues. none of knew whether or not exists currently. basic premise have system has 100% uptime can become more efficient dynamically. here scenario: * hash out system specified set of interfaces, has 0 optimizations, yet confident 100% stable though (dubious, sake of scenario please play along) * profile original classes, , start program replacements bottlenecks. * original , replacement initiated simultaneously , synchronized. * original allowed run completion: if replacement hasn´t completed vetoed system replacement original. * replacement must return same value original, specified number of times, , specific range of values, before adopted replacement original. * if exception occurs after replacement adopted, system automatically tries same operation class superseded it. have seen similar concept in practise? critique please ... below comments written after initial question in r...

i getting message when run web application. runs fine message during shutdown. severe: web application registered jbdc driver [oracle.jdbc.driver.oracledriver] failed unregister when web application stopped. prevent memory leak, jdbc driver has been forcibly unregistered. any appreciated. since version 6.0.24, tomcat ships memory leak detection feature, in turn can lead kind of warning messages when there's jdbc 4.0 compatible driver in webapp's /web-inf/lib auto- registers during webapp's startup using serviceloader api , did not auto- deregister during webapp's shutdown. message purely informal, tomcat has taken memory leak prevention action accordingly. what can do? ignore warnings. tomcat doing job right. actual bug in else's code (the jdbc driver in question), not in yours. happy tomcat did job , wait until jdbc driver vendor fixed can upgrade driver. on other hand, aren't supposed drop jdbc driver in webapp's /web-inf/lib...

when compile c code cross toolchain, linker prints pages of warnings saying executable uses hard floats libc uses soft floats. what's difference? hard floats use on-chip floating point unit. soft floats emulate 1 in software. difference speed. it's strange see both used on same target architecture, since chip either has fpu or doesn't. can enable soft floating point in gcc -msoft-float. may want recompile libc use hardware floating point if use it.
