  1. Matrix vs Ntfy - detective work

    I'm running my own Matrix homeserver for a number of reasons - one of them is simply economical as 'disk space' on a mobile phone is way more expensive than on a server. You can easily slap a few TB into a server with...

  3. Building the kernel with clang: messing around

    The Linux kernel is an ingenious piece of software and I'm pretty confident in compiling it by myself since quite a while - so I was trying to step up the game by doing debian packages. But now as the Kernel supports...

  4. Working my way to automatic kernel builds

    It's pretty obvious, that me maintaining the debian kernel repository which I announced in this post is a lot of work as I offer up to 4 flavors - which are 'vanilla', 'vm' and both for the gentoo patchset, I had to i...

  5. Bash files vs configuration

    You guys know me, I do script a lot of stuff to make my life easier. Starting from my (smart)home to my server maintenance - it just saves too much time. And today I would like to share some ideas on how (not?) to wor...

  6. Yubikey for system auth

    Linux is a beautiful system that can be customized in very many ways - it amazes me everytime how easy or which features I can add to my system for making life easier for me. Today: Login using the Yubikey. System Aut...

  7. Central logging vs dns targets

    Oh boy - I was not ready for a hit like that. But let me start with the whole picture, shall we? I do run a central syslog using graylog and I tend to ship my logs to that device for easier searching and poking around...

  8. ccache on kernels

    As I am building debian packages of recent kernels , I have to build the same thing over and over again - pretty much three times to be exact. Once for 'vanilla', second time for virtual machines and third time for ga...

  9. My own kernel repo

    Debian is awesome. Really. I love Debian - but sometimes the well-aged kernel is a tad too old for me. Currently it's about fstrim and as I'm already doing my own Gentoo-Kernel for Debian , I had to do it properly and...

  10. Building a Gentoo Linux Kernel on Debian

    Debian is a solid Linux distribution with nearly nothing to complain about besides its well aged software. And in my case this 'nearly nothing' was more about the nearly than the nothing as due to the old kernel, fstr...

  11. Smart Home tinkering

    I am not sure if you are aware of Home Assistant , but it's a neat way for me to do some tinkering in my home and wire it all together using Node-Red to save me some coding and get some neat flows set up. And you can...

  12. Replacing disks on FreeNAS

    ZFS is a great thing and the main reason for me to use FreeNAS. But as disk space grew sparse, I had to think about upgrading. As WD brilliantly fucked up their WD-Red series and made a real mess there with SMR and so...

  13. Speed update

    It's quite a fortune that progress finally arrived at my end of the world as the lines were updated. In my case my ISP upgraded my line to be 5 times faster than it was before. Finally.

  14. Homelab-Blues

    My current homelab is basically a vmware ESXi server, a FreeNAS and some other common found components like an UPS, a few Raspis, Switches, WLAN access points... Most of the hardware is old stuff I bought from compani...

  15. Building a system for strong privacy - Part II

    After I have outlined my idea in the first part >/a>, I will now move on to my favorite topic: Adjusting the system a tad more to match our interests My sysctl Config step by step I believe IPv6 is not that important...

  16. Building a system for strong privacy

    I got a small laptop here, which is sadly only 32 bit. To be honest, a bit old-fashioned, but still an unbeatable battery time of 10 hours of normal use. In my humble opinion it's pretty much a sin to throw that box a...

  17. Bread time

    As my server was hitting its capacity limits, it was time to rethink the whole webstack and do some improvements. And that's exactly where I ditched gzip in favor of Brotli. Considering that it's supported by the majo...

  18. The story of a hacked server

    It's not a big secret that I am helping out other people when they have Linux issues - and so I did at this fellows network. In fact, we did a Gentoo server together to give him some chance to learn more about Linux a...

  19. traefik 2.0 vs insecure SSL certificates

    Guess I should quickly explain why someone would want to mess with bad SSL certificates. I mean, it sounds insecure as hell and you are right if you're shaking your head. But sadly there are applications unable to del...

  20. Looking at Pi-Hole

    Pi-Hole is a nice tool to reduce ads on your network. The way it's working is pretty simple: The main component doing the magic is a DNS server, which's job is to give bogus answers for unwanted domains so that the cl...

  21. Fighting the Asus ROG G752VSK

    I have to admit, Asus did a sweet one here, but to be honest, it can be a pain in the rear end running linux - especially sound and touchpad. But regarding sound I was able to find at least some partial solution which...

  22. Looking at Jolla

    Due to me having some time and my old OnePlus One Smartphone, I decided to have a look and find (stock) Android alternatives - something that exists without that rather enclosed Google-Environment. I mean, there surel...

  23. Why Facebook is evil

    Now that's a strong title here guys, but let's have a look for its reasons and start out with some simple math and the way things used to be before most people run into the golden cage of Facebook. We all agree, Faceb...

  24. etckeeper vs git push and branches

    It may sound weird to save /etc in some software like git, but let's have a look why it does make sense: git is a revision control system that tracks changes and in case is able to revert them. Basically perfect for k...

  25. A bit of sugar

    My trusty and ol' VMware server was serving me well since quite some time by now, but to be honest, RAM was always an issue on those boxes. 32 GB namely aren't much. This time I got myself a late xmas present pushing...

  26. Dev Diary - The new CRM - Ideas and concepts

    As I work at a brand new company which is currently being founded, we found out that the common CRM systems available don't match our needs and due to the fact that I am able to code, I decided to hack it myself. I kn...

  27. Skip the Google Setup Wizard

    When playing around with android phones it may happen that the setup wizard crashes and refuses to work. Not nice per se and quite annoying as it prevents us from testing and developing. As I always forget how to get...

  28. BareOS Storage-Daemon on FreeNAS 11.2

    I'm running BareOS Backup on my network to backup all the data I want a crash to survive. Not a big deal honestly, but there's one thing that really bugged me: My FreeNAS wasn't running the Storage Daemon. My old way...

  29. The good, the bad, the ugly....

    Tuesday github hailed me telling me that my password might have been in some logfile and it needs to be changed - two days later, same thing on Twitter. Both cases aren't really to be taken too easy - and both compani...

  30. Huawei P10 lite – About virgins and kids

    There's a proverb in the German language, which could be roughly translated as 'like the virgin got the baby', which describes the process of getting something quite unexpectedly. And so we're standing here, hosting t...

  31. Huawei P10 lite – Poking around

    As I had spent quite some time with Android and ROMs it was time to poke around in the thing called 'stock rom' - that stuff that Huawei gives to us, the end user. And that's where it gets really interesting: The firs...

  32. Huawei P10 lite - Not quite my taste

    Once again there were new devices for customers at A1. So I took a cheap P10 lite, because it made a solid impression at first sight - without looking at XDA. And that's how things started getting messy. But let's sta...

  33. Updating Bareos on Univention 4.2

    One of my basic IT rules is "If you have some software running, do proper maintenance and keep it up to date or remove it." I know, that's one of those simple readings which end up to be quite easily forgotten and dis...

  34. Kernel Blues?

    You know, thanks to Intel's little 'design flaw' in its CPUs and all of that buzz going on, we're forced to patch around a little. This time, the linux kernel bails out *-- * AR /usr/src/linux-4.14.12/tools/objtool/li...

  35. Qubes OS 3.2 - Hands on

    This Hands-on stuff might be uncommon on here, but it's just a transcript and my thoughts to toying around with some stuff. This time it's about qubes, an operating system which is a bunch of VMs on Xen. Not sure yet...

  36. Qubes OS 3.2 - Hands on - Part 2

    After tinkering a bit with the nvidia drivers I noticed that the software Qubes ships as stable is slightly out of date. To be honest, Fedora 23 is EOL since a year now, so I decided to do some updating and the unbeli...

  37. The net and all traffic was equal - mad(e) in the USA.

    Thios Thursday, the government of the United States made it a law. Finally, they managed to shot themselves in the knee again by bringing back censorship and anarchy into the world wide web: Internet service providers...

  38. Smart Tinkering - Part II

    Guess after the echo of that post about smart home stuff, I guess I have to deliver another shot: This time it's a bit more practical. Speaking of a Raspberry Pi II being used to emitting noises every now and then by...

  39. Smart tinkering

    I'm thinking of some ways to work on my home in terms of making it some kind of smart. But smart in terms of having 'some' information instead of being married to information gathering services. Thinking of presence d...

  40. Bare debian

    I love Linux - usually for being quite slim. But on the other hand, using a really minimalist install on debian 9, I need to add a few packages to get around. openssh-server - provides me ssh access net-tools - contai...

  41. My own Etherpad-lite container

    Don't know your stand on outdated and old software on your own system - but in my case, I got a bad feeling about it and it gives me bad sleep. So the following story. We're talking about an Etherpad image done by uni...

  42. Hacking the tribe log

    Ark: Survival evolved is a nice and sweet game and I love to play it. I even run my own dedicated server for my friends. But to be honest, since the notification functionality was introduced in patch 243.0, I heard so...

  43. NTP vs UCS

    Univention UCS would be a sweet "Domain-Controller in a box" solution if there weren't that many pitfalls like setting the NTP server correctly. That stuff is done via "ucr", some univention tool on commandline or hid...

  44. Kernel.org Changelog

    The good old Changelog of the Linux-Kernel is quite a monster to read and I cannot imagine that you'd like to read it commit by commit for just maintaining your kernel builds in case of getting a rough idea what happe...

  45. Sort IPs

    I was doing some research on spam again and had to do some stuff with a couple of IP Addresses. That's where "sort" came in handy as a tool to do what its name suggests.

  46. OpenSSL Cheat Sheet

    Create a strong CSR and private key openssl req -new -nodes -newkey rsa:4096 -out server.crt -keyout server.key Parsing out the data within a certificate openssl asn1parse -in server.crt Checking a certificate/key mod...

  47. /dev/null not found?

    Today I came across a box with no /dev/null. Disturbingly that box even refused to boot. Here's a quick fix in case: Boot with some liveCD and chroot or use some emergency shell and kill the defect dev file in case it...

  48. x2go client complains about some sshd

    Since I am fed up with licensing costs for some TeamViewer solution or any awkward or even complicated VPN stuff I did dig into x2go, a neat solution for sharing some beloved apps on various machines. After all the wh...

  49. What did the LinkedIn Hack mean for end users?

    Thinking back of the year 2012, the 5th of july I have to think of the hack that happened against LinkedIn . For anyone who missed the big news, feel free to catch up on Wikipedia . But why am I thinking of that stuff...

  50. A bit of a nerdish review

    The LinuxDay in Dornbirn is over now. Last weekend to be correct. And I was there, part of the insane NOC team. But what does it mean to deal with such networks? Sure, there's a lot of theoretical stuff what you could...

  51. An open Letter to VMware, Inc

    Dear Sir or Madam, This is an open letter to you. Once again your website brings the joy of being unable to download the files I need in a timely fashion started by a redesign making it horrible to find anything again...

  52. Return to Stock - Nexus 5x

    It's not a secret that I was running Cyanogenmod on my Nexus 5X, but I have to admit, it's time to revert to stock due to various random issues which are getting me mad. So here's a small howto to do so. First of all,...

  53. Show the TCP connections made

    This is a small snippet which has helped me on my server; showing you the top tcp connections made: netstat -atun | awk '{print $5}' | cut -d: -f1 | tail -n+3 | sed -e '/^$/d' |sort | uniq -c | sort -n -r Nothing funk...

  54. Nexus 5X reboots

    My new Nexus 5X was a bit troublesome on pure Android as I was used to Cyanogenmod (nightly snapshots). So I had to do what a girl has to do: Flash that thing. Add Gapps and be happy. Practically, the phone was reboot...

  55. Unbreaking ownCloud with php-7.0.6

    Fix not needed with OwnCloud 9.0.2! Not sure where to start. Good bug reports are usually showing a way to reproduce the bug - so here we go: First, have ownCloud 9.0.1 running with a Redis Cache as a backend. Nothing...

  56. Need for Speed - PHP using a Redis Server

    Today was about optimizing my LAMP stack here because as you know, speed can only be replaced by more speed. Last time I was moving my MySQL server to a different machine, but I was certain that there's more to be don...

  57. Messing around with a database

    I have several virtual machines running in my current setup, offering various services. This is not a bad thing per se - in fact, it increases security by encapsulating services a bit. On the other hand, I ended up wi...

  58. Elephone P8000 and the OTA disaster

    Careful guys, there is an update for the brand new P8000 phone out there which semi-bricks your phone. After this warning, it might already be too late as you might have just flashed the update like I did. That way th...

  59. Friendica Troubleshooting - poller.php

    Experimenting with Friendica might be fun, if the poller script doesn't actually hate you. In my case, it spammed me with thousands of warnings which read as follows: Warning: posix_kill() expects parameter 2 to be lo...

  60. Epic fails: Apple can do too.

    We all laughed about Microsoft error messages. Here's a recent snapshot I made on an apple computer: "Windows 7 or older versions are not supported on this Mac." "Boot Camp only supports the installation of Windows 8...

  61. WP-BlackCheck 2.8.0 - Beta 1

    Quite some time passed, since I really looked into the code for ironing out bugs and added features, but honestly - there is no need to do much, as the plugin works pretty smooth. But nevertheless I did some changes t...

  62. OwnCloud 8.0.3 and some SQL problem

    Today my OwnCloud was due to an update to 8.0.3; As I did so, an SQL error hailed me: Aktualisiere ownCloud auf Version 8.0.3. Dies könnte eine Weile dauern. An exception occurred while executing ' DELETE FROM `oc_luc...

    By now an update to my beloved OnePlus One phone is rolling out and so do a few fixes and some notable changes and a sense of Bloatware: SwiftKey and MaxxAudio. Is this the beginning of the end of a slick and bloatwar...

  65. ccache == more Speed?

    Many people, especially around gentoo linux, do think that ccache is a must-have, reducing compile time pretty much. But is that really true? How much does it really help? Let's nail it down with some facts: ccache pa...

  66. POODLE Security Vulnerability and IE6

    The Facts: As a counter-method against the POODLE-Security Vulnerability it is recommended to disable SSLv3. Internet Explorer 6 cannot deal with TLSv1. For security reasons I did disable SSLv3 here too. Guess that's...

  67. A short Hands-on: iPhone 6

    Everybody around me was going crazy for the new iPhone 6. So I got the chance to get a closer look at one of those devices. Honestly, I am really appalled how cheap the device feels compared to the older 5s (the ones...

  68. A short Hands-on: OnePlus One

    OnePlus does a phone, namend One - the new "Flagship Killer" in town, attacking with solid 32 or 64 GB of storage, 3 GB of RAM and a Qualcomm® Snapdragon™ 801 Processor. Quite some power if you ask me, but honestly -...

  69. A short Hands-on: Microsoft Surface 3 Pro

    I have to admit, I'm a proud owner of the MS Surface 3 Pro running an i7 under its hood. It's my first Windows Tablet, so I do not have references to any of the previous devices. So I'm just giving my personal opinion...

  70. PHP Upgrade

    Today I had to upgrade my PHP version to 5.5 as version 5.4 is getting older. So there will be some small problems with some services here as I have to adapt some of the code pieces used. Sorry for the inconvenience d...

  71. Google-Authenticator - Strike 2

    Google Authenticator surely is a cute thing. But my current solution isn't really matching my taste: one token for every app which makes up a total of 20 token for my daily use - about 19 token too much if you'd ask m...

  72. Google-Authenticator and SSH

    Looking at the current bugs and problems with passwords and authentification, everything is insecure - at least in theory. Believe me, as a sysadmin I have to say, "that sucks". So I decided to choose "Plan G" which i...

  73. Adventures with the RaspberryPi

    Yes, I've been caught by the Raspberry Pi fever. A bit late, but caught for sure. It all started with a friend of mine handing me a box, saying "Guess you can make use of that way better than I could." That's how thin...

  74. Free as in ...?

    Vmware drives me crazy. Today I got aware of a 'new' Hypervisor, the ESXi 5.5 which should be the new and shiny stuff from vmware, dropping the 32 GB wRAM limit. But the first unpleasant surprise awaits us at the new...

  75. ZFS - closed due to overcrowding

    As a fan of BTRFS, I love doing snapshots to keep things arranged during updates. FreeNAS offers ZFS which should do the same. Tested, works and good for backing up my Mac using TimeMachine. Things went smooth until t...

  76. Skype uses SQLite

    Skype uses SQLite too! Even if you don't believe it, but it's one of the most handy things for getting data structured; But as every database, even sqlite needs some love every now and then. On a linux box, the databa...

  77. Starvation

    My mailserver got some nice features to fight spam. One of them is the well known filter SpamAssassin , being the last line of defense here. In theory, a nifty setup, if you kill quite some spam and leave the rest to...

  78. Network too intelligent

    Lately, working with Windows 7 I noticed a cruel transmission rate of 200 B/s while fetching a file from a local server over a highspeed connection. No, I didn't have a typing error in there, it's 200 Bytes per second...

  79. KDE and the last login time

    After the last KDE Update an annoying message popped up at login here, showing me my last login time. Pretty uncool if you want your system to do its stuff automatically without confirmation of such dialogs. So I did...

  80. A N900 in 2013

    Back in August I got me that Linux device called Nokia N900 on eBay. Sure, it's an older device, but you don't need to crack it as it's pretty open. Sure, you can jailbreak, root or do some voodoo with your device to...

  81. Scanning Cash

    While doing a routine install of a scanner I discovered something interesting - an error message while processing a test image: The scanner software recognizes money and refuses to process it, to make it harder for th...

  82. Debian: From 6 to 7

    Debian did release its Version 7 - named after the cuddly Penguin of the movie ToyStory, Wheezy. Time to update? Sure - painless as usual: Backup (did I already mention that I love vmware snapshots?) first, followed b...

  83. No SSD? Take a slow HDD instead!

    Nowadays, when buying a new laptop, you may choose whether you like to have a SSD disk or a traditional 'spinning disk'. There's nothing special about it, you might say but I could observe that the HDD drives used are...

  84. Doing a disk change

    If you run out of disk space, it's time to get yourself a newer one; Basic rule for users. In my case, I'm just the one who's doing the technical work behind, which is less troublesome than the user. To save me some h...

  85. Goodbye Windows 8

    I'm fed up with Windows 8 on my Lenovo W530 and the troubles I am facing. To name a few: No support for the color calibration sensor by pantone, VMware vSphere only works with a few hacks (and doesn't show consoles),....

  86. Suspect things going on

    It's not a secret that I tend to dislike apple for the way they raped BSD to get it useable for the masses, but what they do to me from the programmers point of view, is insane. Let's start out with a simple MAMP inst...

  87. Tracking down problems with Win8 and Linux

    Since quite some time I'm running Windows 8 on my Laptop. During this time I did see and track down quite a few bluescreens caused by malware scanners, drivers and last but not least caused by my Linux install. I am p...

  88. PCs do need care!

    It shouldn't be something new for you that you should care for your computer. No matter if it's a Desktop PC or a Laptop. If you don't care, your machine might end up with a bunch of problems. On the other hand, are c...

  89. Headcrash

    That's how things look like: A dead disk, after having a headcrash. Look at the carved ring. All the dirt inside is more or less swarf.

  91. Notes for the Atrix

  92. The SSD for daily use

    My last post was about some technical facts regarding the Crest 6 Master by Angelbird where I promised to publish some results of my daily-use test with using my Lenovo W500 . First of all, keep in mind that the disk...

  93. The Need for Speed

    Now it's official - I got myself a brand new SSD disk to get a little bit more speed out of my laptop. For comparing things I did a short hdparm test with my older Seagate Momentus XT as I am too lazy to look up some...

  94. Two years at the W500 - and now?

    My W500 isn't really an old PC, but I have to admit that I do hit some performance limits by now. So what now? A new notebook? Geez... Looking back at the upgrades already done: The internal Harddisk drive was already...

  95. IceCreamSandwich vs Motorola Atrix

    My Motorola Atrix is running on Gingerbread which is a little outdated by now. The only way to get it updated at the current state of writing is an unofficial update to ICS/JB which is tempting because of the new func...

  96. MSSQL Emergency Mode

    There are a few undocumented things about the MSSQL Server 2000 missing in the knowledgebase of Microsoft. That's a way to get a database marked as suspect into emergency mode: use[master] go execute sp_configure 'all...

  97. MS-SQL Recovery

    There are two kinds of customers: The ones who do backups and those who didn't have data loss yet, ignoring all good advice and best practices. However, in the end it's always us, the IT crowd being yelled for to look...

    Replication of MySQL databases is an easy thing if you disregard its complicated documentation. So this is a short howto on how to do it: The my.cnf file of the Master server needs to have the following entries added:...

  101. ThinStation

    I love simple workstations. Especially if they do what you expect them to - and nothing more. You can imagine that I like ThinClients, web terminals and stuff like those. Those days I stumbled over ThinStation, a smal...

  102. Syslog-NG rants

    Today was the day of another lovely Syslog-NG update, which included upgrading the config file. In other words, browsing the docs for any important changes and migrating those. Isn't that exactly one of our favorite t...

  103. Managing /etc/ using git

    The directory /etc/ is vital for our Linux systems as it contains (most of) the configuration files of the system. In case of trouble, it's quite common, that you'll visit this directory after browsing through syslog....

  104. Clickable shell scripts

    I am working quite a lot using shell scripts to make my work easier and a few of them are even on my desktop to perform some one click actions. Sadly this doesn't work on my mac as it just gets opened in an editor, ig...

  105. Activating SSH on OSX

    My beloved Lenovo notebook actually is gone for repair due to some hardware trouble - so I am stuck with a not-so-beloved mac. For working I do need a sshd daemon running, which is - hooray - shipped per default. You...

  106. MSSQL vs Access via JET/ODBC

    If you are dealing with a greater amount of records in a Microsoft Access database, it's recommended to use a SQL server as a backend database to handle those and get rid of unpleasant surprises. Usually those servers...

    Today someone pointed me towards SAC 8.1 which is the middleware for my eToken which I am trying to use on Gentoo (pure 64bit) for quite a while. After downloading and unpacking I peeked at the binaries shipped, as th...

  108. Unpacking a .deb package without dpkg

    Debian is a nice distro, as long as you don't need to mess around with its packages on other systems. Today I was playing around with the SafeNet stuff for eTokens on gentoo - and all I had was the debian package, but...

  109. Thinking about comment spam again

    It's a fact that I don't have much spam here since WP-BlackCheck pretty much kills it all, but as I am just one user among many out there, I'd like to know if I miss some kind of spam on your end or which bugs you fou...

  110. WP-BlackCheck 2.6.1

    A new version of WP-BlackCheck is out - once again. The changes are more or less just a few cosmetic fixes: Add counter for reported IPs Fix bar graph text issue New Webservice URL

  111. Extending Grub2 to detect Memtest+

    Grub2 using Gentoo doesn't detect if a Memtest86+ boot image is available - so I tried to come up with a solution which looks as follows: 20_memtest86+: #! /bin/sh set -e # grub-mkconfig helper script. # Copyright (C)...

  112. Testing Grub2

    Gentoo is a distribution where you decide about software you install. This was reason enough for me to give Grub2 a spin. Installation wasn't that hard after unmasking and keywording the grub package: echo "sys-boot/g...

  113. Albanian translation for WP-BlackCheck

    It was quite a pleasant surprise when I checked my mails and found a message where someone offered help on my Wordpress Plugin WP-BlackCheck: Taulant Ceka sent me the albanian translation, which I'm cheerfully adding...

  114. Blacklist uses reCaptcha

    A small update: The delisting process for my blacklist slightly changed - it's using reCaptcha by now to prevent some folks from having bad ideas. Further enhancements are already waiting to be implemented.

  115. WP-BlackCheck 2.6.0

    Spam changed - mostly the trackback and pingback stuff started to get annoying - maybe a sign of the upcoming vacations? The situation on site here forced me to adapt my plugin. The changes so far: Fix of the Update N...

  116. Who's connected to my MSSQL server?

    Today I was trying to restore a backup of our MSSQL server when a user decided to drive me crazy by not disconnecting after telling anyone that we need to do that restore. So I fired up the management studio and had a...

  117. Looking for a proper phone

    Looking at the mobile phone market I have to admit the trend doesn't make me happy. Nokia buried Maemo and Meego and decided to use Windows, Apple forces you to use iTunes which is a pain in the ass on any non-macinto...

  118. Skype vs Growl 1.3

    Since working on my Mac, I have to admit that I got used to use Growl for notifications as it's a pretty way to get notifications in a non-disturbing way. But since Growl 1.3 Skype went on strike - just like a couple...

  121. Bleeding edge BTRFS on top of a stable kernel

    People asked me way too often on how to test new BTRFS features - a reason for me to do this article. It's nothing special, but you have two possibilities to do it: Possibility number 1: You pull the patches you want...

  122. Exchanging SSL Certificates at the ESXi

    The ESXi server uses self-signed ssl certificates by default. As you know, this isn't really what I prefer, especially since I am working with CAcert certificates. But sadly there is no nice GUI solution for replacing...

  123. Rebooting IT

    My old server machines are too noisy - which is an undeniable fact and the reason for consolidating machines. It was a decision which didn't make me happy, but logic told me to do so and offered a new challenge to me....

  124. Check XFS fragmentation

    Using XFS means, that you have to deal with fragmentation of your files. Disregarding fragmentation, XFS is a wonderful filesystem which never caused any problems here. To check fragmentation, we use the xfs-debug too...

  125. Bad RAM

    I guess there are many ways to drive a sysadmin crazy - I even experienced a few by now; But the most effective one of all seems to be bad memory. Let me tell you: Nowadays most systems that I get to look at are Windo...

  126. Windows Registry broken

    Today I got an unpleasant surprise - an emergency call due to a broken computer running Windows 2000. Pretty ancient, I agree. The cause for the disaster was power loss and it refused to boot anymore, asking for a rei...

  127. BlackCheck Stats

    It's been quite a while since I started to work with some statistics about what my plugin does, observing the kind of spam being blocked and it's been quite cool to see: Most of the spammers are posting way too fast a...

  129. Apache 2.2.20 is out

    As the bugfixed version 2.2.20 of the apache webserver hit the portage tree on gentoo, it's safe to remove the security hacks which leaded to some uncool problems with Git. Finally things are going back to normal.

  130. Apache 2.2 Bug

    Todays issue did hit the apache 2.2 webserver while handling range requests. Range requests, according to HTTP 1.1 are not bad at all as they were used for resuming downloads in example. But where an overly wide range...

  131. Going online via the N900

    Today I was on the road again, carrying my laptop with me. I had the need to go online with my laptop. Having my Nokia N900 with me, this shouldn't be a problem, right? So my first step was connecting the devices via...

  132. IT changes

  141. OpenVPN vs Win7

  162. Hotlinking is a problem

    Hotlinking or Inline Linking is using media hosted on foreign servers on a different homepage. In other words, it is stolen traffic as someone does have to pay for it - and that's the one hosting the image. Some guys...

  166. CentOS and Corefonts

    The ms-corefonts are fonts done by Microsoft - which aren't included with CentOS by default - just like many other useful packages. If you want to install them, you can either fetch an RPM file from someone else or ju...

  167. Linux configs versioned

    Sometimes it's really fun to mess around on a Linux box - but it also can be a mess to get things back to a working state after breaking some configurations. As we are just talking about text files, things shouldn't b...

  170. WP-BlackCheck 1.8 released

    Reviewing my last version I spotted a few lines of code which could be considered as dead and a little bug which hammers the SQL server with a stupid query. As booth things - dead code and bugs - shouldn't be in a goo...

  175. Nokia N900

    I own a Nokia N900 since some weeks now and I couldn't let it go as I had to collect info for this posting. One of the hardest things to do as a blogger is collecting info for you, the audience. As I won't get any com...

    As Wordpress changed a few details in their API, I updated the WP-BlackCheck Plugin to reflect those. The current Version is now 1.5 which is available on wordpress.org

  177. WP-HeadlineAnimator

    Changes regarding PHP and Wordpress rendered the configuration of the plugin unusable. This and the switching to qTranslate instead of Polyglot made me do a new version. If you need Polyglot Support in the plugin agai...

  178. Killing Spam

    Let's have a look at one of my favorite topics today: E-Mail Spamfilters. They are a quite helpful tool for keeping the inbox clean as long as you don't fully trust their work. I know this sounds paradox, but what hap...

  179. Live and let live

    Looking at the IT world, there are many systems to work with and many arguments against them. It's amazing, but it's common that users flame each other. Linux guys pick on Windows users, Windows users hit apple. In th...

  180. Mac-Tip

    Screenshots are cool for technical support tasks as they are useful for analyzing error messages. I noticed that Apple users usually send quite many screenshots (as I get them quite often). After a while a friend told...

  181. A MacBook

    I have to admit, I didn't really look at Macintosh. Well - disregarding the apples in the store of course. But since quite some time, I am having to deal with those systems. So I got one. As a hardcore Linux-User, I'm...

  182. A portable friend on the road

    Looking at the current mobile phones, it seems like those little companions would like to be a notebook replacement. But to be honest, something's missing - and that's a full keyboard - a keyboard that allows you to t...

  183. Another reason to use Linux?

    There are many reasons for me to use Linux - one of them is the WGA checking which currently has the nerve to brandmark my Windows 7 as a "non genuine copy" since I've applied the latest updates. To improve the situat...

  184. Offline tools for blogging?

    You know, I love blogging - even if I didn't post much during the last days as I was on the road quite much. To be able to blog offline, people invented various editors like the Live-Writer which works great - as long...

  185. Facebook vs StarBlog

    You might have noticed that I am hanging around on Facebook , where I also published the RSS feed of this blog - mainly to extend the range of my posts. Sounds great, but you know what's been said about theory and thi...

    Do you still remember my Lenovo W500 notebook? I was writing about the setup and the issue with the switchable graphic cards. You remember: It got two cards - one for the hard work and one for saving power. Switching...

  187. Teamviewer now for Linux

    I guess you all know my passion for Linux and that I am doing most work with it. But sadly there are always applications you need windows for, which requires a license and so on. But now the good news: Teamviewer is n...

  188. CentOS locked into a chroot

    It's not only a question of security if you decide to lock some services of the system in a chrooted environment to minimize the damage they are able to cause. We know debootstrap as a cool and simple way of doing a v...

  189. Untrained Spamfilter Blues

    I migrated my mailserver a few hours ago to a complete new system to have a better groupware solution and less noise. But honestly, I am already missing the old patchwork system as its spamfilter was working very very...

  190. Groupware

    As a system administrator there are many important things in my life I shouldn't miss - one of them are my e-mails. They have grown as important as coffee for my life. Choosing the right e-mail solution is as importan...

  191. CentOS strikes again

    If things are running smoothly, things might get really nasty. Today's special: KVM on CentOS 5.4 My plan was giving KVM a shot for virtualizing a couple of machines. So I inserted the CentOS CD and did a network inst...

  192. Extending CentOS

    If you are a company, Gentoo Linux might not always be the best choice for you - especially as it's not supported by enterprise products like the kerio mailserver, various backup systems or some database engines. So I...

  193. PHP on CentOS 5.4

    Dealing with CentOS isn't always fun, but at least it is a distribution suitable for professional work. But all that doesn't help if it comes to problems. The problem today is called PHP. CentOS ships with PHP 5.1.6 w...

  194. Doing iSCSI targets on ZFS

    As ZFS did quite well here - even after messing around with disks, I decided to give it another try. This time I am out to use its features on other systems. But to do so, I need to share it. As I am running virtual m...

  195. Disk failure and ZFS

    ZFS is a beautiful filesystem - even in case of hardware failures, as it was build to deal with them. Allow me to demonstrate a defective disk on a Raid-Z1 pool. As long as only one disk breaks down, it is still funct...

  196. My first glance at OpenSolaris

    Today I was having my first glance at OpenSolaris. Getting the ISO burned, booting the LiveCD and all this didn't take long and the system was booted, welcoming me with a Gnome Desktop environment - which I personally...

  197. Certificates and the mobile phone

    It has been quite a while since I started to get SSL Certificates working on my server machines - so it was time to get that stuff running on my mobile phone too. You might wonder now why the phone would need such a c...

  198. KDE4 drives me crazy

    Since a system update during the last days, my system does strange things. As taking a closer look, the troublemakers are related to KDE. My first clue was a broken dependency which causes services to crash - so I ran...

  199. Let's get active

    Today is a wonderful day, the Linux Day in Dornbirn - the place to gather my CAcert points to become an active assurer for the Web of Trust. As it was possible to take the assurer test on site - god bless the inventor...

  200. Virtual machines vs clock

    Virtual machines and their clocks can be quite nasty - at least if I am working with them. Maybe it is because it is impossible to kick against virtual machines? Are they that nasty because they know they are safe? Th...

  203. syslog-ng trap

    Today syslog-ng acted up as the most bitchy program of the day - which I won't forget that soon. Due to a configuration issue the program ate 100% CPU power of one core. This was quite annoying as it happened without...

  204. The second glance at Windows 7

  206. Now with new Certificates

    It shouldn't be a new topic to secure your data while sending it across public lines like the internet. This usually happens using server certificates, which are made once and never touched again - if self signed. In...

  207. Speed up Firefox

    Our beloved and well known friend and companion Firefox can be quite slow - especially if you are having it for a while now. But what is the reason for that performance loss? Let's investigate and see what we can do....

  208. CD ISO on DVD

    A small hint from the chaos lab: I had to burn an ISO done for a CD disc but we didn't had a CD to burn it. The only thing we had was a bunch of DVDs. It is a big waste, but CD Images also work on DVDs.

  209. First impressions of GRUB2

    If a known computer magazine writes about the new grub2 version, it cannot be that bad at all, isn't it? True, Grub2 is still unfinished, but it should be already quite useable. So why not giving it a try? The first s...

  210. Online Backup - Review

    As I am using Online Backup as a virtual data safe since some time now, it is time to look back and see what it did: The amount of data I am keeping safe is something around 2 GB. Sure, this doesn't seem to be much bu...

  211. Switchable Graphics

    The topic isn't something new - to equip a computer with two graphic cards to make it save power. The idea bases on the fact that you don't need high end graphical performance for your daily work and so a less powerfu...

  212. A different kind of suicide

    It is official by now that there are maniacs out there who already migrated their root-filesystem on BTRFS . So why not joining those freaks? Theoretically it shouldn't be a big hassle: Boot a Live-CD, mount and backu...

  213. Online-Backup

    Backup is always one of those beloved topics of system administration as nobody cares, but cries on data loss. This posting shouldn't rate a method of backup - it should just introduce online backup as a way of doing...

  216. 64 Bit?

    My (new) Laptop got a 64 bit CPU doing the number crunching in it - and of course enough RAM to do it all. So it isn't a miracle, that the OS they delivered with it, was Windows Vista 64. So I looked over the whole in...

  217. WP-Blackcheck - Statusreport

    My Blacklist service is running for quite a while now and it it's time to look at the result. Sure, it isn't much as not many people provided feedback by reporting the IPs, but for now we have collected about 60 IP Ad...

  223. Internet Explorer and Network shares

    Last post I have ranted about apple doing crap, but to be honest, it isn't really better on windows - it's just different problems like being unable to execute a binary file from a network drive. As the error message...

    Windows can be a real dirty system regarding wasted disk space as you might have noticed. A current case showed amazing numbers. The common TEMP-Directories, found at C:\WINDOWS\SYSTEM32\TEMP and some stuff in the use...

  226. cmake

    I guess I can't keep my hands off my gentoo box trying to test new things until stuff breaks. This might sound tragic, but if you'd ask me, it's those things you learn most of as fix the things you have broken while t...

  227. Moving the server machines

  230. Lenovo W500 - Part 3

  238. Moving mails to different servers

    Is it fate or simply bad karma that I'm always bothered with mailserver boxes? Or is it that they just cannot find anyone else crazy enough to even give it a try? I'm not sure, but it's me again, pushing mailboxes fro...

  239. Enough joking

    As the title says, I'm getting serious about my server boxes - no more software raid, no more running all that websites using the same user, no more kidding. As the new mailserver is already productive, the second IBM...

  240. Manuals in PDF format

    Manuals are one of the vital things of the IT field, the source of information about how to handle certain programs and problems. Surely they are not always top, but always better than nothing if you are able to read...

  241. A new MTA

    I guess you all know the common problem with cheap hardware being used as a server box, don't you? I'm fed up with those troubles and decided to use some professional hardware. It doesn't sound that bad running a desk...

  242. Windows 7 Beta

    I guess I was part of the crowd who took the Microsoft server down by downloading the new beta version of Windows 7. Surely I am not the biggest Windows fan on earth - and never will be as I cannot use an operating sy...

  243. Working remote

    All people who have done helpdesk work or another support job in the IT area do know the problem by heart: How do you direct users to do exactly what you want them to do? Well - usually you tell them every mouse click...

  244. But apple can do

    I recently got the chance to check out an apple server box and work with it for a little while, as the admin there was absent and some stuff had to be done - especially the updates which I had to do. Fine thing for su...

  245. KDE 4 - still no thanks (yet)

    As I was hit by KDE4 due to the ~arch keyword on my gentoo box in october, I was playing with KDE4 for quite a while. I even had the two versions in parallel. But due to starting up wrong version of binaries due to PA...

  246. JSSpamBlock 2.1?

    You might remember my ranting about the JSSpamBlock plugin of Paul Butler, thinking of porting it to the actual WP release . I have decided to keep an eye on it fixing various bugs for keeping it compatible. JSSpamBlo...

  247. Buttons without JS

    It is always fun looking at old work you have done a long time ago, isn't it? In my case it is a site that was used on my old playground www.stargazer.at , where everything started. One of the problems of the old time...

  248. JSSpamBlock is (really) dead now?

    After Paul Butler's Announcement of the end of JSSpamBlock maintenance, I was not really worried about the plugin itself, as it still did its job in a perfect way. If you think back, there are enough unmaintained plug...

  251. HeadlineAnimator

    If I have to think back at the times I have started developing the HeadlineAnimator for having a fine signature at the discussion boards, I tend to look at the documentation I wrote those times as I cannot exactly rem...

  252. KDE 4 - no thanks (yet)

    It was quite a surprise as yesterdays update list showed KDE4. They have unmasked and keyworded it for ~x86. Having mixed feelings, I started the emerge procedure which took a while until my system was up to date agai...

  253. Cracking passwords - the end

    This is now the official end on cracking generated passwords here. After running for 77 days and 3 hours not even a single password was cracked. So this is the last status report: guesses: 0 time: 77:03:40:35 c/s: 971...

  254. Logitech MX310 vs G5

    After five years of quite fine service, my Logitech MX310 mouse broke down. Personally, it's a big loss, as we have had many lan parties together. As ranting doesn't help, I was forced to go out to the shopping center...

  255. Patch me gently

    Have you ever asked yourself what a patch exactly is? Well - let's take a closer look at the things your mother used to fix your trousers - a patch. That's quite close as it fixes a hole. But patches in the it field c...

  256. Login via Bluethooth

    If you try to go over the top with some things, then you should really do it instead of just using some tiny hacks. What about logging into your computer using a mobile phone? Sounds cool, huh? So let's use it and get...

  257. Living without aRtsd isn't bad at all

  260. Login with the USB stick

    That I am lazy if it comes to typing much shouldn't be a secret by now, but mentioning it here might be wrong too - but it was the main cause for doing some research for an alternative login method. Fingerprints may s...

  261. Microsoft Key-Changer

    No, this is not a mistake: Microsoft offers a small tool for changing the product key of windows xp or vista. Ok, they call it 'updating the product key', but that's just a different word for it. In general, I like th...

  262. SATA after the install

    Windows always got a bag of fun stuff to keep us busy with. But sometimes the fun is over and you need to reinstall it from scratch. As my Laptop was running with the original install since quite some time now, I gues...

  263. pfSense vs simple Router

  267. YouTube selfmade - Part 1

    Have you ever asked yourself how sites like YouTube are working? Why it is possible grabbing videos from there that simple? How it's built? I guess that's some questions now. But if you don't mind, I'll answer some......

  268. Cracking passwords - a test

  272. Nostalgia

    I've never thought of having to install MS-DOS 6.22 again in my life. But today I had to - I even needed Windows 3.11 for Workgroups for getting some ancient box to work. The install started with three floppy disks, a...

  274. IPSec between Linux and the NetScreen

    VPNs are a fine thing, especially if you are not at home and you need to access your beloved network. I am using VPN connections since I have implemented them at my Pfsense using openvpn. Since I got my NetScreen/Juni...

  276. Static webpages

    Are you 'up to date' if you are still using a static webpage today? I wouldn't say that there is a global answer to that question and everybody's got to find out for himself. Usually I'm a big fan of automatism and te...

  277. Apache and OpenSSL

    My SSL Certificate for the webserver expired - so I had to generate a new one, which is a perfect topic to blog about. Regarding SSL Certificates, there are two possibilities: you may buy an official one or you may ge...

  280. Finally it arrived!

    After one week delay, the third service pack for Microsoft Windows XP arrived. You won't believe it: It's even available via automatic update. But what's inside? First of all, it's a huge file being 313 MB which means...

  281. Update: Finally it arrived!

    After the big download, I kick-started the installer and I couldn't believe my eyes: That service pack wants to have 1475 MB free space while installation - true, that number sounds scary, but it wasn't better with th...

  282. Microsoft Delays Windows XP Service Pack 3

    Since Heise announced that Microsoft will release the Windows XP Service Pack 3 on the 29th, I didn't sleep too well, as I really want to grab it as soon as possible. Sure, I use Linux, but this doesn't mean that I am...

  283. Support the way we like it

    Today I'd like to talk about the support team of Netscreen as they're doing a great job. That's the story so far: After installing my firewall, I had to register it as I needed to activate DeepInspect. Web registratio...

  284. If it takes some more time

    ... it was usually me doing fancy stuff on the network. Yesterday my blog was unreachable due to firewall maintenance. Yep, I have finally implemented the Netscreen Juniper and threw the old box away. I know, it is cr...

  285. Enforcing vs Permissive

  290. ORDB.org strikes back

    I guess you know the ordb.org blacklisting service for mails - but did you know that it was taken offline long time ago? It did not report spammers since that time, but nevertheless many mailservers are still querying...

  291. Copy On Write?

    While browsing my documents for BTRFS stuff, which was recomended by Rei , I came across a funny term named 'Copy on Write'. I guess, you're already shaking your head, asking yourself what the heck I would copy on wri...

  292. mplayer and internet radio streams

    mplayer is one of the media players, you can use for everything on linux. There are nearly no formats you cannot decode. Regarding internet radio, I like this player as it works without bells and whilstles straight fr...

  293. Syslog NG and permissions

    Syslog NG and permissions are a topic on its own - especially if you like to keep your system safe. Imagine, you run a process to parse your syslog files, which you do not want to run as root. Sounds easy? A first try...

  294. Groupware Patchwork

    Thinking back on my mail system here, I usually get that uncomfortable feeling in my stomach as the server structure was more or less some unordered patchwork which was started long time ago. Everything started back w...

  295. Kernel Update

    Just for the records: The downtime we have experienced was just a reboot for booting a new kernel to be up to date again

  296. BTRFS 0.13 is out!

    Chris Mason released a new btrfs release where he corrected some bugs - the nastiest one was a checksumming bug. But the thing you'll notice most, are the speedups.

  297. I'm fed up with Drupal

    I am using Drupal since quite a while for www.stargazer.at but regarding the latest security bulletins, I'm quite fed up with it and I'm doing things on my own again. A small design massacre is about to be done...

  298. Samba or libcap-2.06?

    After wrecking my system by doing some updates, I was forced to use revdep-rebuild again. So I went to bed for letting the PC work as it wouldn't need me for compiling. The next morning I woke up and went to the scree...

  301. Goodbye Acer

    My old Acer TravelMate 800 got a new owner by now - but life is quite ironic, as I bought the scooter from her. Let's see how things develop. To be honest, she doesn't really have a clue of windows or linux. So why no...

  303. Tux on the rocks

    It is not a secret anymore that you are able to freeze your system and save its state to disc for resuming work later. Windows calls it hibernation and linux talks about suspend to disc - but it's about the same thing...

    As requested, here is a working kernel config for the Acer tm800 for the 2.6.23 series of the gentoo sources. Hope it helps - have fun. Download .config here

  308. Flock?

    There's much noise about that social webbrowser Flock. Because of that noise, I decided to have a closer look. The first impression of Flock is, that you got some heavily modded Firefox, made for exhibitionism 2.0, as...

  309. Compile in RAM?

    I know, I am not always kind and nice to my PC and I love to exaggerate. That's why I have moved portages' playground to tmpfs. So far so good, we're compiling. Small packages may like it, but I got other packages lik...

  310. Thanks a ton, asshole

    I'm loving it. Some dumbass used my domain for dispatching his junkmails into the world. So all the bounced mails are piled into my mailbox. Since I've been using SPF, such things happened less often - but I guess it'...

  311. Video for the mobile phone

    Nokia phones cannot handle common video formats. That's a fact we cannot change. If you are using Windows, Nokia gives you a handy tool for converting. But if you are using linux, you are lost? Well. First of all, lin...

  312. Reading Bios info

    I don't know what you think of rebooting for getting information from your computers' bios, but I would take it as quite disturbing. Bios supporting the SMBIOS/DMI standard can be queried using the dmidecode command....

  313. SQLgrey

    I am using Greylisting since quite some time to keep malware away and I have to admit, it is a blessing: As many malware and spam programs do not respect the RFC, they just try to deliver their load just once - so the...

  314. No 2.6.23 yet

    There was really big noise around the new kernel 2.6.23. But is it really worth it? I have waited for the gentoo-sources patchset, added my patches and started testing to satisfy my curiosity. But there were more prob...

  315. Upgrade failed

    It is not pretty if you need to wait for websites being loaded. To avoid that, we decided to do an upgrade to 4 Mbit. 4 Mbits should be a fine reason to accept a little downtime, shouldn't it? After the upgrade the te...

  316. Rebirth?

    As you know, I own an Acer TravelMate 800 since quite some time. As I have used it for server stuff during the last month, it was time to start with a new install as there was too much junk on it. Considering the fact...

  317. Testdriving 2.6.23

    Since today I am running the new gentoo-sources patchset, which is using the new 2.6.23 kernel sources. The update was more or less pain free, disregarding some sandbox violations. But those were avoided using FEATURE...

    As you know, I am collecting unknown malware and send those files to the anti virus laboratories to let them find a way to cure infected machines. Since some time I was forced to run the malware sorting on my laptop a...

  320. Did you notice?

    If you didn't already notice, I changed the header image on my blog here. I know, I should have done that sooner, but I was too lazy for. But why just now? I have discovered Inkscape . Incscape is a vector drawing pro...

  323. What if an interface starts up?

    What happens if you bring up an interface using an init script on gentoo? Do you know? Already figured out how to start services depending on what interface is up/down? The gentoo-way is done in /etc/conf.d/net. Looki...

  324. Death of my KDE profile

    As sysadmin I am talking about Backups every day, as things can break very easy. But are backups always usable, up to date and compatible? I was testing some software as suddenly my KDE crashed and the profile assista...

  325. BTRFS 0.8 is out

    You've read enough about the road trip? Good news: this posting here isn't about. Honestly, it was fun without a pc, but kind of strange. So back here I was checking for updates and as far as I can see, Chris Mason re...

  327. Hardening

    Linux is simple as long as you get the idea in behind. I am using it since some years for now and I need a new challenge. So I decided to have a look at the hardened projects and maybe using SELinux. But where to begi...

  328. Real security or just a nice try?

    During the last days I had to install SUSE- and RedHat Linux on some machines and I had time to take a closer look at booth. The first thing on RedHat that caught my eye was SELinux as a cute way of limiting damage on...

  329. Cleaning out on Gentoo

    I think you already know the problem of fat systems. To prevent this, I did a cleaning session on my Gentoo installation here. This is not only about unmerging old and unused software. Think about your USE-Flags again...

  330. ReadyBoost? ReadyRecycled.

    Since Vista is out, the IT scene got a new buzzword: ReadyBoost - This thing should be able to speed up your vista box by adding the memory of an USB stick to your systems' memory. But is this a real brand new concept...

  331. Adam and Eve blogging

    I know, I have not bashed the catholic church since some time - so here is a small side blow and a pointer to Robert Basic. He is writing an article about the things you should NOT do in a blog or on a website. It is...

    As Adsense was not the 'killer' here, I am trying LinkLift. Let's see what happens.

  333. Dhclient, that bitch

    Well. You are used to more beautiful words here, but that program caused some trouble in cooperation with the Networkmanager tool. The Story so far: I am using Networkmanager to configure my network interfaces due to...

  334. Beep!! Beep!!

    Linux can be annoying with all its bells and beeps, especially if you're working on a console. But there is no need to kill a wire or smash the speaker to silence the computer. This is a nice way of doing so, without...

  335. Stargazers Overlay

    As I am working and managing several gentoo boxes, my local portage overlay was the most annoying thing as it was never in sync. So my solution is setting up my own subversion repository containing my ebuilds to distr...

  336. Development snapshots and Mondays

    As I am working very much with subversion snapshots and unstable stuff, there is a basic rule I have noticed: Never check out code on Monday mornings. Why is that? Let us assume an open source project. Most people hav...

  337. PC-cillin Internet Security

    The license of my PC-cillin Internet Security suite, that I got some time ago has just expired. This is a reason for me, to write a small review. The colorful GUI might look playful to the expert, but it is structured...

  338. Wordpress, Joomla or Drupal?

    Today it is important to have a website with the latest bells and whistles and to show what you got. But all this requires much work if done the old and static way. Many sites are using CMS systems as a backend to mak...

  339. Good things coming from above

    The old german proverb saying that good things are coming from above and the fact that north is shown 'above' on maps make me think. In fact, things discussed on heise are often a preview on what is about to happen in...

    There is great noise in the media since the new kernel has been released. The new features are told to be the killer. Well... amazing... but is the new kernel already useable? I had to face that question a few times t...

  341. If things are working

    If the PC is working and stable, tweak it. At the moment I am playing with LVM - logical volumes. That way I can resize my partitions the way I need them on the fly. If you want to do something advanced, move the root...

  342. Taken from RedHat

    The LVM Package does not offer a great GUI for managing volumes. In fact, everything is to be done on CLI. RedHat did a nice GUI for Gnome. First of all, I searched a test install for the files to do me a tarball as I...

  343. There's a new Filesystem in town: BTRFS

    On the 12th of July Chris Mason mailed to the lkml.org mailinglist introducing his new project, a filesystem for a Datacenter, called BTRFS. Although we are not talking about a final version, the technical specificati...

  353. Spam is expensive

  357. My two cents on KDE 3.5.7

  358. My two cents on XFS

    The XFS Filesystem was developed by Silicon Graphics some time ago. 1994, to be correct. I loved it because of its speed and reliability. Its B+Tree structures made it extremly fast with directories and the maximum fi...

    No, I am not talking about the IT version of a fairy tale but a small networking tool to secure your network: the captive portal What the hell am I talking about? Captive portals are authentication layers on firewalls...

  360. It’s getting quiet around the WP-HeadlineAnimator

    Yes, it is getting quiet and there is hardly any feedback on my plugin. Nothing here. Not even on wordpress.org or mail. All the requested features have been done and a bugtracker has been set up for if it is needed.

  361. Fighting Spam
