  • Anyone know a working CSS selector hack that works in recent Safari but not chrome ?

    - by user318144
    The title sums it up. I'll get this out of the way and say I am aware that css hacks are dirty ugly horrible things. Sometimes dirty problems call for dirty solutions though :) So does anyone know of a css selector hack that works for recent safari versions but is not a general webkit hack ? My site behaves properly in chrome but has a bug in safari. So if anyone knows how i can select an element to only have a certain style in safari let me know!

  • VIM plugin for updating C++ function definition

    - by Sunny
    I'm looking for a VIM plugin that can do these kind of thing. Let's say I have a function in a .cpp file void myFunction(int arg1, int arg2, int arg3){ //code } The function definition is defined in the .h file. So every time I change the function name or add a new argument to the function, I have to go back the the .h file to do the same. Is there a VIM plugin that can automate this task?

  • How to "grep" out specific lline ranges of a file

    - by Mike
    There are often times I'll grep -l whatev file to find what I'm looking for. Say the output is 1234: whatev 1 5555: whatev 2 6643: whatev 3 If I want to then just extract the lines between 1234 and 5555, is there a tool to do that? For static files I have a script that does wc -l of the file and then does the math to split it out with tail & head but that doesn't work out so well with log files that are constantly being written to.

  • C#. Where struct methods code kept in memory?

    - by maxima120
    It is somewhat known where .NET keeps value types in memory (mostly in stack but could be in heap in certain circumstances etc)... My question is - where is the code of the struct? If I have say 16 byte of data fields in the struct and a massive computation method in it - I am presuming that 16 byte will be copied in stack and the method code is stored somewhere else and is shared for all instances of the struct. Are these presumptions correct?

  • How to make hudson build only most current build.

    - by MikeU
    Question How do I setup Hudson so that if one person triggers a build, Hudson will put it on the queue and wait lets say 2 minutes, and during those 2 minutes if another build is triggered it will replace the older build on the queue with the new build? This way if there are 2 builds in those 2 minutes, Hudson will only perform the last build.

    I am reading the Head First PHP/Mysql book and they say to store both the user's username, email into cookies and sessions. Is it safe to assume that everyone nowadays accepts cookies?

  • Looking for a fast hash-function.

    - by Julian
    Hello, I'm looking for a special hash-function. Let's say I have a large list of strings, if I order them by their hash-values they should be ordered quasi randomly. The most important point is: it must be super fast. I've tried md5 and sha1 and they're using to much cpu power. Clashes are not a problem. I'm using javascript, so it shouldn't be too complicated to implement.

    - by acadia
    Hello, I have 3 tables and I am joining these 2 tables as follows: SELECT EMP.FNAME,EMP.LNAME,EMP.AGE,EMPD.TQ,EMPD.TA,CTY.CITY_NAME FROM EMPLOYEE EMP,EMPLOYEE_DETAIL EMPD, CITY CTY WHERE EMP.EMP_ID=EMPD.EMP_ID AND EMPD_CITY_ID=CTY.CITY_ID I want to display records even if City record is not in CITY table. For eg. if City_ID record for say 10 is not in City table but there is an employee detail record with City_id 10 it should display City_name as null instead of not displaying the record at all. Appreciate your help

  • Help me choose between XML or SQL Lite on android

    - by Ngetha
    I have an android app that periodically, say once a week downloads content from a server in XML. The content is used by the app, different Acitivities use different parts of the content. My question is a design one, should I save the data in SQlite or just keep it as an XML file, which one would be faster to read? The app can only use one content piece at a time, which means subsequent XML content downloads replace the old one.
