When I initially received my new X1 Carbon I was very excited at the new hardware. More pixels, more lumens, more cores. After I got over my initial euphoria, I noticed that some things didn’t work, and confirmed such by a very helpful Archwiki page. Some of the things that didn’t work include ACPI suspend-to-RAM sleep (since corrected in a BIOS update), the the fingerprint sensor (still outstanding), and the WWAN LTE Cat9 card that Lenovo seems so proud about.
Here is the presentation material for my talk entitled The Dark Arts of SSH. Please note this is a single HTML rendering that includes presenter’s notes.
As promised to my audience, here are the slides from my presentation titled Building your First Linux Kernel.
After initially running RemixOS, the new Android build for PCs, I decided that I would rather play with booting it natively from my SSD instead of from a USB device. Performance should be better, it would free my USB thumb drive up for other duties, and it would make booting more convenient. This turned out to be a relatively simple operation. What follows is my methodology for doing that. Please note that these instructions assume you are running Linux.
I’ve always been one for trying out new operating systems, so when I heard news about the latest desktop-conversion effort from Jide I wanted to give it a try. RemixOS is a proprietary offering based on the work of android-x86, which aims to bring the stock Android experience to commodity PCs. RemixOS adds on interface and convenience changes to make the operating system more usable on PC hardware. This includes UI changes such as multi-windows and a classic ‘desktop’.
Recently (the past few years actually) we’ve been experiencing that Mercurial has problems scaling to it’s activity. Here are some statistics for example: 24550 Mercurial heads (this is reset every few months) Head count correlated with the degraded performance 4.3 GB in size, 203509 files without a working copy One of the methods we’re attempting is to modify try so that each push is not a head, but is instead a bundle that can be applied cleanly to any [mozilla-central](https://hg.
We have quite a bit of infrastructure around this including Tinderbox Pushlog (TBPL) and more. This post deals with the infrastructure and problem we face while trying to scale the ’try’ repository. A few statistics: The try repository currently has 17943 heads. These heads are never removed. The try repository is about 3.6 GB in size. Due to Mercurial’s on-wire HTTP protocol, this number of heads causes HTTP cloning to fail There are roughly 81000 HTTP requests to try per day To fix problems (mentioned below), the try repository is deleted and re-cloned from mozilla-central every few months There are a number of problems associated with such a repository.
