mydumper – nice alternative for mysqldump

Posted on 2011-04-01 by Oliver

I’m using MariaDB. Now, I had the idea for smaller DBs to use the SQL dump and store that in a version control system such as Mercurial or Git. However, the ordinary mysqldump creates quite unreadable dumps. Since the version … Continue reading →

Billiger StackOverflow-Abklatsch auf Deutsch

Posted on 2011-03-10 by Oliver

Einfügung (Update 2): liebe aufgebrachte codekicker.de-Mitglieder. Für die offensichtliche und unbewußte Täuschung durch meinen durch die Zeit zurückgereisten bösen Klon kann ich mich nur entschuldigen. Dieser Beitrag wurde im Original am 10.3. um 3:21 (UTC, also 4:21 dt. Zeit) eingestellt. … Continue reading →

Top ten disk space hogs in current folder

Posted on 2011-03-07 by Oliver

du -cks *|sort -rn|head -11|awk ‘{printf “%-8.2f MiB\t%s\n”, $1/1024, $2}’ NB: first item is the total size, so it outputs eleven lines. Update: a better version is this one: du -cks *|sort -rn|head -11|awk ‘{printf “%-8.2f MiB\t”, $1/1024;\ for(i=2; i

Posted on 2011-03-07 by Oliver

Had some trouble with the built-in twentyten images. The header image is saved inside a serialized hash in the database complete with the protocol and server name as well as the blog home URI. The problem with this is if … Continue reading →

Visual Studio 2003 and DEP

Posted on 2011-02-21 by Oliver

Some time ago I enabled the alwayson setting for the noexecute switch in boot.ini. Turns out some older programs don’t like it. I had already found out at some point for Borland C++ Builder 6, but this time it was … Continue reading →

Encounter of the third kind

Posted on 2011-01-03 by Oliver

When I flew back to Iceland, there was a guy who literally had a red hat (or fedora) on. Initially I thought I should ask him whether he’s a user of Linux – guessing some “red hat” connection, but then … Continue reading →

Problem: you have one external IP and want to run separate services on different hosts behind the router. Here’s a small script to DNAT the router to the host behind it. Netfilter will take care of the return traffic (so … Continue reading →

So no Inline Assembler in 64bit Delphi? Get over it!

Posted on 2010-12-02 by Oliver

Honestly. I’m seeing people go on and on about that issue, while I can’t help noticing other much bigger issues with Delphi all the time. No PDB support strikes me as a pretty big issue for one, or getting a … Continue reading →

Hah, und es geht doch

Posted on 2010-11-26 by Oliver

Ich bin ja in Sachen Namespaces auch in C++ schon konservativ, daher benutze ich in Python vorzugsweise: import module statt: from module import * da letzteres mir ja alle Symbole ohne Rücksicht in den aktuellen Bereich übernimmt. Nachdem ich zuerst … Continue reading →

Haha, that was so predictable …

Embarcadero is continuing to dig its own grave! The way Embarcadero treats legit customers is akin to the way the movie and music industries treat their legit customers. The paying customer sees the FBI warning (and isn’t allowed to skip … Continue reading →

“The system cannot execute the specified program.” #2

Posted on 2010-11-08 by Oliver

I did indeed solve the issue reported here. The problem must have been somewhere between my ears. Once you do it right, it works 😉 While sigcheck from Sysinternals is a very nice tool, it simply does not compare to … Continue reading →

“The system cannot execute the specified program.”

Posted on 2010-11-02 by Oliver

There is a pretty interesting article over at winprogger.com about the problems connected with IMAGE_DLLCHARACTERISTICS_FORCE_INTEGRITY (set through /integritycheck ever since VS2005) and ERROR_INVALID_IMAGE_HASH (aka Win32 error code 577). Now, I’ve been fighting with this problem for two full days and … Continue reading →

Painful lessons I had to learn again and again

Posted on 2010-11-02 by Oliver

Since this is something I’ve stumbled over several times now and since it is discussed in Microsoft’s documentation only as if there is only the option to import it into your store, i.e. within your user account. Now, I was … Continue reading →

Fighting with Windows 7 SDK

Posted on 2010-11-01 by Oliver

I’ve been fighting with the Windows 7 SDK which kept complaining that I have no Visual Studio 2005 or 2008 installed. Well, I don’t have 2008 installed, but I do have 2005. Problem, however, was that most posts on the … Continue reading →

Check it out: Visual Studio 2010 Help Downloader

Posted on 2010-10-13 by Oliver

Mathias pointed me to the Visual Studio 2010 Help Downloader. Will give this a try soon. I hate when I have to be online to access the docs. But the VS 2005 docs are obviously not up-to-date for Windows 7, … Continue reading →

Kleines Cheat-Skript für “Drakensang – am Fluß der Zeit”

Posted on 2010-10-05 by Oliver

Wie man schon von mir weiß, bin ich ein Cheater. Ich lege mehr wert auf die Geschichte welche mir ein Computerspiel erzählt, als darauf langwierig die gleiche Stelle wieder und wieder zu versuchen bis es gelingt. Hier ist ein kleines … Continue reading →

SQLite index optimization

Posted on 2010-09-18 by Oliver

Learned one fascinating fact tonight: when creating indices for a table in SQLite the order in which the columns are indexed seems to have a huge impact on performance. On the table in question, which has 20.2 million rows, one … Continue reading →

Seriously?

Posted on 2010-09-10 by Oliver

So Embarcadero released version XE of the RAD Studio. Great stuff. Would love to buy it, but for a private person buying an upgrade is quite pricey. 800 EUR or 700 EUR until September 30th as a special offer. As … Continue reading →

cvsnt [server aborted]: Couldn’t open default trigger library: No such file or directory

Posted on 2010-08-18 by Oliver

To my surprise I noticed CVSNT is now only available for money (and compared with my other development tools for a lot of money, so I’ll stick with Mercurial which comes with plenty of better features for which I would … Continue reading →
