(not entirely true, I needed a Windows Virtual machine) I wanted to run a BIOS Update for my HP ZBook 15u G4. Unfortunately, HP provides updates only for Windows. Linux users are used to such sorrow - but I will most probably stick back to other vendors in the future, where the Linux support is… Read More »
I love the Civilization series. One of my favourites is Beyond Earth, where luckily a Linux Version exists on Steam. Awesome! 🙂 Unfortunately under Arch Linux this doesn't work out of the box but needs some fixing. First of all you need to run steam-native, instead of steam. For debugging it's the best to run… Read More »
Some time ago I got annoyed by some movies encoded in h.256 are not running smoothly on the Kodi of my Raspberry Pi 3. h.256 is a block-oriented quite new video compression algorithm, that is unfortunately not supported natively by the hardware decoder on the Raspberry Pi 3. So it has to be done in… Read More »
Flops is a nice tool for benchmarking floating point operations of a CPU. Under Arch Linux i had some problems compiling it, because the static linking towards openmp was not working properly. I've made a fork, fixed the issue by removing the -static flag (and replaces -std=c++0x to -std=c++11) and a pull request in the… Read More »
I need to learn OCaml for one of my computer science courses. Although I am more the procedural programmer type, I like some of the concepts of functional languages and am also using them on a daily basis. Some of the concepts are quite handy and nice - list comprehension, filter and lambda functions. They… Read More »
... and yet another unpatched security hole in Windows 10. This time it's the Internet Explorer and Edge. Sent to Microsoft 3 months ago, still no patch out there. And this will be the last post ranting about Windows. Everyone knows about their security policy and how much you should trust them.
Today my server was down for like 2h because of a misconfiguration by myself in the Let's encrypt certificate (in the usage of the acme.sh script). Now everything is operational again.
SHA1, the old secure hashing algorithm is now broken in practice. See the Google Security blog post on the first SHA1 collision. SHA1 was already theoretically broken 2005, when Prof. Xiaoyun Wang announced a differential attack. By 2010 the NIST decided to announce SHA-1 as deprecated. SHA1 is still in use in BitTorrent and on… Read More »
... and how to deal with it right: Bug filed and fixed on February 17, patches are already in circulation. Exploit will be made available in some days to allow the administrators to update. The fix was just a two-liner but still: Fixed-on-the-same-day-as-filed. That's how it should work 🙂 And in the Windows world we… Read More »
