Well, as a Webdeveloper, german language sucks.  I have a from. In the head, there is at the first place:  &lt;meta charset="utf-8"&gt;   I also checked the header. The following is set:  Content-Type:text/html; charset=UTF-8   In php.ini my default-charset is:  default_charset="utf-8"   The problem is in HTML/PHP because when I write Umlauts (äöü) directly in the database, PHP gets the right string, when I var_dump it. On the other side when I fill out the textarea and send the form, the var_dump for the POST-Parameter has everytime 2 questionmarks instead of the Umlauts.  ä -&gt; ??   How can I fix it?
I'm setting up a new server and want to support UTF-8 fully in my web application. I have tried this in the past on existing servers and always seem to end up having to fall back to ISO-8859-1.  Where exactly do I need to set the encoding/charsets? I'm aware that I need to configure Apache, MySQL, and PHP to do this — is there some standard checklist I can follow, or perhaps troubleshoot where the mismatches occur?  This is for a new Linux server, running MySQL 5, PHP, 5 and Apache 2.
How did the AT-ATs get to the surface of Hoth? Is Linux Virtual Server old, or is it standing still? Based on this question: , LVS may be the right solution for my problem.   But when I went to its homepage , I found that LVS has been updated since Nov, 2008. The world's moving fast, and I don't know if LVS was obsolete or not.  Is LVS standing still, or there're some better solutions to replace it?  Thank you so much. Let $F$ be a field and $f: \mathbb{Z} \to F$ be a ring epimorphism.

I am trying to use bibtex for the first time. I am on windows 7, using TeXstudio. I am trying to follow the steps of .  I have created a .bib file, put it in the right directory and written the code in my .tex file. However, I do not know how to compile bibtex with TeXstudio (I looked around in the menus but didn't find it).   Most tutorials I found don't explain how to do it, or say to run a command, which I'm not sure how to do.  Any help much appreciated! Where do I find out how a command/environment is defined? Say I want to redefine the itemize environment, or make a modified version of it. I want to know how it is currently defined. Where do I find this information? If it's some particular package command, I can just look at the .sty file for that package, but if it's something more basic, I don't know where to look...  Is there a reference manual of where all this stuff is explained? Or is there a file in the depths of my texmf tree I should poke around in? Is there a Windows standard way to do things such as "start fan", "decrease speed" or the like, from C/C++?  I have a suspicion it might be ACPI, but I am a frail mortal and cannot read that kind of documentation.  Edit: e.g. Windows 7 lets you select in your power plan options such as "passive cooling" (only when things get hot?) vs. "active cooling" (keep the CPU proactively cool?). It seems the OS does have a way to control the fan generically. How to install the latest Arduino IDE? I have an Arduino UNO, which I need to get working with Ubuntu.
