not employed by Oracle in any kind, the only advantage VirtualBox (still) has over all the other virtualization systems: was designed to be cross OS from the start and does that pretty well. Holy Crap! Google (crazy guys) ported KVM […]

it is interesting to see what kernel+filesystem the distributions rely on. Kernels: While CentOS is still on 3.10, Debian is believing in 3.16, and SUSE is “latest” with it’s 4.4 Version kernel. http://www.omgubuntu.co.uk/2015/04/linux-kernel-4-0-new-features https://www.heise.de/newsticker/meldung/Linux-Kernel-macht-Versionssprung-auf-4-0-2557302.html you can upgrade with Debian to […]

updates are a bless (fixes to problems, keep system secure from hackerz) but also a curse (it might break things) on systems that follow the UNIX K.I.S.S principle, they should “just work”, to the extreme of (kernel) live patching (currently […]

versus is the wrong word. They are both great great GNU Linux distributions with a different focus and imho the perfect combination. Debian (apt based) “the universal operating system” (because has great hardware compatibility amd64 (64Bit intel) arm64 armel armhf […]

imho: CentOS is a rock solid server operating system. Why is CentOS perfect for servers? a server (usually) is build for a specific purpose and should have as little software installed as possible (more software = more reliability, speed and […]

first of all: i (still) love VirtualBox. The ability to migrate VMs between Windows and Linux servers is really cool, and it is still free to use. NO other Virtualization software can do that! 🙂 and that is exactly my […]

WARNING! WARNING! WARNING! BACKUP BEFORE UPDATING ANYTHING! it is also recommended, to do extensive testing of updates on a 1:1 test-system before updating production! while security is important so is speed/availability/uptime/downtime. upgrades especially of kernel and virtualbox need to be […]

Update: as of 2019-01 and CentOS 7.6 the below setup may fail by now, for those reasons… BUT you CAN compile the latest kernel and all modules yourself (DON’T BE SHOCKED! YOU CAN DO IT! IT’S NOT ROCKET SIENCE!… just […]

update: 2019-01 if you are having trouble getting VirtualBox Additions to run on your guest vm, you might want to checkout this article and compile your own kernel. how to compile latest kernel under debian: https://dwaves.de/2017/06/28/debian-compiling-the-latest-kernel-compile-customize-kernel-download-install-linux-kernel-headers/ it is a little […]

BUT: only 1.5% of all OpenSSL instances were found to be impacted by this security flaw HeartBleed revival party? why complexity is the enemy: “parser written in C was never properly tested for security problems” says golem.de “The Heartbleed bug would […]

Especially important: how fast does existing x86 software (as virtualmachine or docker container) can be run on very energy efficient ARM SoC? Apple already demostrated that with their M1/M2 (soon M3?) ARM based chip designs (congratz!) it is possible to […]

warning: no guarantee of completeness! contains ads! (but owner of blog get’s nothing, maybe source of source does) Are the odds against the (itsec) defenders? It certainly feels that way, because no human can ever find all bugs, so Fuzzing […]

let’s say: in theory – it works in reality – there are (currently) massive sata harddisk driver problems between esxi 6.7 and kvm-qemu’s virtual harddisk admin-user know: esxi is hardware picky (Dell bought VMWare in 2004 so, “officially” only Dell […]

first off the praise: kvm-qemu is a high performance nicely scriptable virtualization system if it works, it can do pretty things 🙂 especially like the x11 forwarded virt-manager gui over ssh (yes it is a bit slow… but simplicity at […]

how to fix stuck permanent function (Fn) key BIOS / Firmware updates: but why? if everything works, vendors often say “leave it like that” because updates can have unforseen sideeffects and not all computers are “exactly” the same X-D (a […]

Yes! RSS (“Really Simple Syndication“) FEEDs are still a very practical thing to follow certain websites & blogs & news outlets & aggregators & stay current on those platforms. Instead of letting big media outlets shovel news indiscriminately down the […]

UPDATE: 2022 may have to appoligize to HighPoint and ALTERNATE, as other RAID systems such as the AMD RAIDXpert2 based systems (same concept) are also STALLING during ATTO Disk Benchmark in Direct I/O mode. So the ATTO Benchmark MIGHT be […]

Apple: from RISC CPU (PowerPC) to CISC CPU (x86 Intel) back to RISC CPU (ARM) what is the difference? short version: CISC CPUs (usually need more energy) have more instruction sets, for example: model name : Intel(R) Core(TM) i5-4200U CPU […]
