I see a very high value in compiling my own Qt, and on top of it all the KDE-made software that I use. This makes it very easy to fix bugs and add improvements to the software I use on a day to day basis. Nowadays I think many developers use distro packages for Qt or KF5 or even the whole environment except for the one app they're working on, but in my opinion this leads to "silo" thinking, with workarounds in upper layers rather than fixing issues at the right place.

The Lenovo Thinkpad P50 is quite a nifty laptop. However installing Linux required some digging around, so I'm writing this up for others to stumble upon it when looking for answers to similar issues. Read More

Clazy [1][2] just got support for suppressing warnings by reading a special comment in your code. The syntax is similar to what krazy has. Ignore the whole file: // clazy:skip Read More

Recently the question was asked in the KDE forums <a href=https://forum.kde.org/viewtopic.php?f=285&t=130260>how we handle advanced settings. While there is neither a best practice nor a common approach in KDE software, we actually discussed a similar concept in respect to the Plasma control modules (KCM). Read More

Well, consider them unhidden now: if you missed a structured place to link bugs.kde.org big/wish reports with KDE Phabricator tasks, look no further. One or more "See Also" fields of the bugzilla (top-right side) are useful points of integration. Example: link, see the screenshot below. Read More

Earlier this week, the loved one of a man I used to babysit was pushed into the path of an oncoming subway train car, by a stranger, and soon after died of their injuries. Read More

About two months ago I blogged about clazy, a Qt oriented static analyser. Since then it has moved to an official KDE repo http://anongit.kde.org/clazy, got an IRC channel (#kde-clazy @ freenode) and also many fun new checks. Read More

Intro or what are Kexi objects? Kexi objects are the top-level entities of type Table, Query, Form, Report, Script or Macro. They are compared to perhaps separate document types except of course they are not physical files (in Kexi nothing touches physical files except the database that handles the actual storage but this is rather an implementation detail).

If you're seeing crashes lately, and they look like: (gdb) bt #0 0x00007ffff6790913 in QString::~QString() () from /usr/x86_64-pc-linux-gnu/lib/libQt5Core.so.5 #1 0x00007ffff680fd89 in QHashData::free_helper(void ()(QHashData::Node)) () from /usr/x86_64-pc-linux-gnu/lib/libQt5Core.so.5 #2 0x00007ffff6828e14 in (anonymous namespace)::Q_QGS_globalEngineCache::innerFunction()::Holder::~Holder() () from /usr/x86_64-pc-linux-gnu/lib/libQt5Core.so.5 #3 0x00007ffff620fed8 in __run_exit_handlers () from /usr/x86_64-pc-linux-gnu/lib/libc.so.6 #4 0x00007ffff620ff25 in exit () from /usr/x86_64-pc-linux-gnu/lib/libc.so.6 #5 0x00007ffff61fa617 in __libc_start_main () from /usr/x86_64-pc-linux-gnu/lib/libc.so.6 #6 0x000000000040f5b9 in _start () and valgrind says something like: Address 0x21d41498 is not stack'd, malloc'd or (recently) free'd Read More

Today I have the pleasure to announce that Marble is the first popular virtual globe that ships and visualizes the Behaim Globe. The Behaim Globe is the oldest surviving terrestrial globe on earth. It was created between 1492 and 1493 - yes at the same time when Christopher Columbus made his first voyage towards the west and "discovered" America. This fact makes the Behaim Globe very special and also subject to scientific research: It documents European cartography during that era and it's probably the only historic globe which completely lacks the American continent. These days the Behaim globe can be visited in the Germanisches Nationalmuseum in Nuremberg, Germany. The Germanisches Nationalmuseum (GNM) has kindly granted the Marble project permission to release the photo scan material of the Behaim Globe under the CC BY-SA 3.0 license and they have supported us in bringing it for the first time to the users of a widely deployed virtual globe: Marble. Right now our users can immediately download the Behaim Globe from inside Marble by entering File->Download Maps (or download it via our maps download website.). Read More
