Don’t run this on any system you expect to be up they said, but we did it anyway
This is the story of how we upgraded over 2000 Ubuntu production servers – turning over millions an hour – by installing the operating system in memory, wiping the root disk and reinstalling the OS back on disk from RAM. We did it, there was zero data loss and it saved us lots of time and...

Terminal and shell performance
There’s a great MSR demo from 2012 that shows the effect of latency on the experience of using a tablet . If you don’t want to watch the three minute video, they basically created a device which could simulate arbitrary latencies down to a fraction of a millisecond. At 100ms (1/10th of a second), which is typical of…

Fastest Way to Delete Large Folders in Windows (2015)
The common way of deleting files and folders in Windows is via Windows Explorer (a.k.a. File Explorer ).

OpenBSD on the Huawei MateBook X
The Huawei MateBook X is a high-quality 13" ultra-thin laptop with a fanless Core i5 processor. It is obviously biting the design of the Apple 12" MacBook , but it does have some notable improvements such as a slightly larger screen, a more usable keyboard with adequate key travel, and 2 USB-C ports.

50 days of postmarketOS
We are fed up with Android's endless forks! Fifty days ago I have announced postmarketOS, a touch-optimized, pre-configured Alpine Linux , which can be installed on smartphones.

ZFS Is the Best Filesystem For Now
ZFS should have been great, but I kind of hate it: ZFS seems to be trapped in the past, before it was sidelined it as the cool storage project of choice; it's inflexible; it lacks modern flash integration; and it's not directly supported by most operating systems. But I put all my valuable data on ZFS because it…
