Even it it doesn't break your filesystem anymore: Performance is subpar in all aspects except sequential read/write even compared to ZFS. high snapshot count degrades performance and lot's of gotchas you discover after using

As someone in the early 30s that mostly wasted away the last 15 years due to anxiety, internet addiction and procrastion and unability to finish stuff: My only advise to younger ones is to work on your problems early on and focus on a stabl

everything embedded - OpenWRT/LEDE uses busybox with ash - Android uses mksh? that only supports a subset of bash features. Every Debian/Ubuntu has ash as /bin/sh that only supports POSIX.

This is dangerous advice. At least on Ubuntu 16.04 with stock kernel running due to memory pressure into swap kills the systems. Basically everything times out and you can only hard-reboot. Without swap you have an OOM at least something yo

So just use cgit on your 128mb box and don't complain about gitlab? It's like installing Windows 10 on a machine with 1gb memory, starting Photoshop and complaining about swapping and that it's running slow. Gitlab runs fine

I'm having a hard time organising and especially switching tasks and getting meaningful work done when multiple things that are unrelated fall together. Having a single thing do to and beeing able to just leave work would be great but

It's probably bullshit. If there would be an effect that can be reliable recreated using only a CRT and certain modulations it should not be hard to setup a double blind placebo controlled study and become famous. I presume there was a

If you don't need good single thread performance and don't care about Performance/Watt that much you can get used servers for very little money with lot's of DDR3 memory (128GB+) and these X5670 als dual cpu systems. If

Chernobyl was not unlucky. This was organisational failure and technical failure - few to none knew about xenon pit and that positive void coefficient was a compromise at the time to fulfill the demands. Fukushima? I'd say ignoring the

For OpenWRT - at the moment the current code is at the fork called LEDE - here is a ToH: https://lede-project.org/toh/start - both projects want to reunite but it seems progress is slow - use the 17.01.2 release for LE

I guess some books and talks from people who discovered stoicism i.e. maybe by reading Albert Ellis and put around some modern day self-help stuff. William Irvine, Ryan Holiday, Tim Ferris and so on. Stoicism as a label and some nice quot

Unpopular opinion: Ditch everything GNOME, glib, vala, GTK and focus on making KDE, Qt, QML first class software. QML is powerful and is quite fast and can at least be made fast. KDE needs UI and design polish but the foundations are IMHO m

If you recreate the bug on Linux and have something like a simple reproduder I guess that the ZoL devs are more than happy to fix or at least understand it: https://github.com/zfsonlinux/zfs From reading the pull reque

Anything ath9k PCIe would be my guess. Driver is open-source, little to no closed firmware and it's battle tested and good Linux support. No 802.11ac through but for sniffing it shouldn't matter.

> why is a router broken say 10% of the time? My guess would be that WiFi drivers are kind of quirky - if you follow OpenWRT/LEDE development there a lot of issues that appear only on heavy load or under certain situations - causes

Shared hosting is high trust? You are basically one stolen credit card and 5 minutes away from giving strangers SSH access to a host with lot's of customers that often process sensitive data. Might be true that it's not that impor

This approach was also under attack while negotiating TTIP and other trade agreements. Ironically it was badmouthed as unscientific - as if it's better to throw any new heavily patented chemical on the market and let science figure out

Lot's of embedded vendors have plenty of GPL violations - Linksys and Ubiquity for instance in the case of grsecurity it was appearently Wind River. Apparently even no source code even if you purchased a device.

I guess it's not too far from the reality - at least since Windows 10? Windows got a lot of stuff that is better than Linux in that regard. Control flow guard, Device Guard Virtualisation, ALSR - the current stack/heap guard page
