  • I am working on an A/V switch with the kids and was annoyed by the fact that the page talking about how to do that did not include anything like a schema (it has some bus drawing... who cares?!) This being said, the concept is perfect and works just fine. It's just hard for me to see that when the person just says connect this here and that there and voilà!

    Original A/V switch information:

    http://www.engadget.com/2007/03/13/how-to-make-a-solid-state-a-v-switcher/

    The source is a gschem file as created by gEDA Schematic Editor (a free tool you can get on Ubuntu.) Already the free ...

  • Using BIND as a Master and a Slave simultaneously

    I got BIND on two servers (the named service). Each server is at the same time a master and a slave depending on the domain name. For instance, I host http://www.alexishouses.com on my server and http://www.m2osw.com on my company's server.

    Up to here, easy.

    The slaves are expected to update themselves whenever the master emits a change in a zone.

    Somehow, one of my domain names would not work at all on the slave (company's server). I searched and searched and I just couldn't find out why it was not working. Finally, I tried to search the

  • Today I found a table describing the keystrokes you can use to generate different letters in another language than the bare ASCII set used in the US. For example, it is nice to use "à" in French whenever necessary because "à" (a preposition) has nothing to do with "a" (a conjugated verb).

    Microsoft includes that feature for most of their software. It may not work in all software, although you can always open wordpad and then copy and paste the output. (Notepad is not enough, it does not support UTF-8 or Unicode too well.)

  • I created a disk for my WinXP that I run on my virtual machine. This was my first Windows install and when creating the drive, the system used the wrong size. I did not notice until the whole installation was done. So... I got a hard drive of 8Gb which was not really large enough since installing all of those things for XP, including some updates, I got at a little over 5Gb of data.

    Since I wanted to install many other things such as MinGW, it was quite tight!

    I looked around and found a page on Ubuntu Forums that explained out to do the job: How to resize Hard Drive in Virtualbox. It's

  • I have been wondering how to lock a few rows and/or columns on a side in Excel. I have seen that being done many times, but did not know how to do it myself.

    In the Windows menu (Before Office 2007) and in the View menu (Since Office 2007) you will find an option named Freeze Panes. You have three selections:

    1. Freeze the selected top rows
    2. Freeze the selected left columns
    3. Freeze the selected top rows and left columns

    If you just need one row and/or column, place your cursor in the A1 cell.

  • My compamy creates many software and some are translated. Up to here, nothing serious.

    Now compiling can be a problem as older versions of msgfmt do not like the BOF character at the start of text files. It has to be clean UTF-8, but no BOF.

    Anyway... Now I compiled and I need to test the results. So I need to run in French, Spanish, etc.

    The normal way under Unix is to do this:

       LANG=es program-name options
    

    Although the name of the language can be a bit more complicated such as es_ES.ISO-8859-1.

  • Today I tried to run WinXP on my newly upgraded Linux Ubuntu 12.04. It did not work... that's because the aqemu graphical interface tries to run qemu which was replaced with specially named emulators: qemu-i386, qemu-system-x86_64, etc. (try ls /usr/bin/qemu* to see a complete list on your system.)

    So... I got the command line from the aqemu graphical interface, did a copy / paste and replaced the name with qemu-system-i386 and got the emulator started as expected. That worked fine, but then the window remained small (640x480) which I wouldn't care much if I weren't really using ...

  • By default, when postfix is installed with postgrey, all the emails that are not blocked by some other means are all passed to postgrey.

    What if you have a customer who doesn't want to wait forever to get his/her emails?

    Well... you need to bypass postgrey (and good luck to him/her in regard to heavy spamming...)

    The setup requires two additional entries as defined here:

    # in main.cf
    smtpd_restriction_classes = permissive
    permissive = permit

    Here we define a new class called "permissive" (which is case sensitive!) and that we will use in the restriction access file.

  • To look at your processes, threads, modules, network, etc. at a quite low level, you can use the SysInternals Tools. System Internals was bought by Microsoft. So the new site is at Microsoft.com. The old URL still functions though (http://www.sysinternals.com).

    Note that since that purchase Microsoft has worked to ameliorate their libraries to give these tools legitimate access to the data they query!

    In most cases, these tools work against running processes and not against the source (not the .exe, .dll, etc. files, but their loaded/in memory versions.)

  • This page is a test page of the Menu per Role module for Drupal (Yes. This site is a Drupal site, did not guess yet?!) The module controls whether a menu entry should be shown to a given set of customer without having to change the permissions of the destination. This is particularly useful whenever the destination is not a node.

    As of Dec 2008, I'm the maintainer so I needed a place to test the module. Here it is.

    You will need to be registered and logged in to see the corresponding menu item in the drop down. Good luck.

    And the following is a node with comments that I use to test the ...
