  • How to transform multiple line into one line in bash stdout ?

    - by Samantha
    Hello, I sometimes do this in my shell : sam@sam-laptop:~/shell$ ps aux | grep firefox | awk '{print $2}' 2681 2685 2689 4645 $ kill -9 2681 2685 2689 4645 Is there a way I can transform the multiple lines containing the PIDs into one line separated by spaces ? (It's a little bit annoying to type the PIDs every time and I really would like to learn :) ) Thanks a lot.

  • Any netbeans features that will make my day?

    - by Kris
    Hi all, I've recently gotten quite fond of netbeans for my php work because of the XDebug integration. It has made me all but forget about textmate (which imho still beats netbeans for the little things) What do you think is the one awesome netbeans feature I should know about, and more importantly why and how do I use it? I'm asking this to optimize my skills in the use of the IDE and based on the idea that what works well for others might just work for me (and hopefully others).

  • Drupal Module Themes - Default CSS?

    - by derekerdmann
    There's tons of documentation out there on how to override the appearance of Drupal modules, but I keep finding the docs for writing the original theme to be a little lacking. On this note, how can I tell Drupal to use a specific CSS file for my custom module's block output?

  • Please recommend PDU SMS format code or library for .NET or C++

    - by Pavel Radzivilovsky
    I have been searching a lot for a chunk of code, or a library to format SMS messages in PDU format and had little luck. They were either huge monsters with terrific dependencies on everything way above my requirements and a very obscure interface, totally not justifying the straight-forward, although rather complex encoding. Being on the edge of creating a NIH, my question is - have encountered the same problem and how have you solved it?

  • SQL Server, varchar data to nvarchar data

    - by Øyvind
    I've got a database with collation Danish_Norwegian_CS_AS and lots of varchar columns. I'd like to convert all this data to unicode, but haven't found a way to convert this data yet. If I've understood correctly, the encoding used is UCS-2 little endian. For example I've got a column containing 'PÃ¥l-Trygve' which is easily converted with C# to 'Pål-Trygve' using Encoding.Default.GetString(Encoding.UTF8.GetBytes("PÃ¥l-Trygve")); Is there a way to do this conversion in the Microsoft SQL Server client?

  • epoll_wait: maxevents

    - by someguy
    int epoll_wait(int epfd, struct epoll_event *events, int maxevents, int timeout); I'm a little confused about the maxevents parameter. Let's say I want to write a server that can handle up to 10k connections. Would I define maxevents as 10000 then, or should it be be lower for some reason?

  • jQuery slider not visible after container div is toggled

    - by Shahar Evron
    I have a page which contains a jQuery-UI horizontal slider, created using a little function, inside a div which can be displayed / hidden by clicking on it's title, using $.toggle(). Problem is, once the div is hidden, when it is expanded the slider is gone. A simplified demo of the problem can be seen here: http://arr.gr/jquery-issue.html (file contains all relevant source code) - when clicking the "Advanced Options" title to hide and then show the div, the slider is no longer there. Any suggestions on how to work around this?

  • Java api to get windows Special folders

    - by SvrGuy
    I once found a nifty little library that used JNI to allow java applications on Windows to get the locations of various "special" directories on windows. I can't for the life of me find it again... In particular, I need to get the location of the "All Users" (shared) "Application Data" directory. So, anyone have a bullet proof way in Java to locate the "All Users" "Application Data" folder? It needs to be bullet proof.

  • Big O, how do you calculate/approximate it?

    - by Sven
    Most people with a degree in CS will certainly know what Big O stands for. It helps us to measure how (in)efficient an algorithm really is and if you know in what category the problem you are trying to solve lays in you can figure out if it is still possible to squeeze out that little extra performance.* But I'm curious, how do you calculate or approximate the complexity of your algorithms? *: but as they say, don't overdo it, premature optimization is the root of all evil, and optimization without a justified cause should deserve that name as well.

    Hi, I'm just starting to play around with GTK+ and I wanted to stop bad habits before they happen. I see that GTK+ seems to be a little based in HTML/CSS and I was wondering if there are any reasons to avoid using tables for layout.

  • RC2 key schedule

    - by calccrypto
    Can someone explain how the RC2 key schedule works (particularly the very beginning of it)? i know it uses little endian, but my implementation is not working for any key except "0000 0000 0000 0000" Test Vector Key = 88bc a90e 9087 5a Plaintext = 0000 0000 0000 0000 Ciphertext = 6ccf 4308 974c 267f im assuming that the first thing to do with the key would be to change it into bc88 0ea9 8790 5a and yes i know RC2 is not even used anymore, but i would still like to know
