ab71e5··on The SD Association has an official SD card format utility [Win/OS X/Linux]
Pro tip: Use a read only rootfs and use overlayfs to write any changes to ram instead of the SD. Then you just gotta put your state on a USB drive, network etc.
ab71e5··on GitHub was having issues
Ah was wondering why pull requests did not show up
ab71e5··on Ask HN: Do you struggle with flow state when using AI assisted coding tools?
Not OP but I have the same problem. I've found some things just work better for me, like using (neo)vim (or emacs I guess) instead of something like vscode helps me stay in the zone more.
ab71e5··on Xfinity using WiFi signals in your house to detect motion
This is hacker news, of course there is a need
ab71e5··on Malicious compliance by booking an available meeting room
Wow, was it actually 90 minutes of standing?
ab71e5··on Eight or more drinks per week linked to brain lesions
Beer is about 5%, so 14 times 20 = 280ml of beer, pretty standard beer glass size
ab71e5··on The Pentium contains a complicated circuit to multiply by three
That assumes booting is a synchronous action instead of asynchronous, giving time to fetch a cup of coffee
ab71e5··on Yocto, RockPi and SBOMs: Building modern embedded Linux images
Which book was that? The bootlin course slides are pretty good
ab71e5··on How I configure my Git identities
Great tips, did not know about the `hashconfig:remote` option.

Currently dealing with a difficult setup where we have subrepos (so just using an `~/.ssh/config` alias for github.com:org does not work), some dependencies downloaded with CMake CPM, and working in a vscode devcontainer.

ab71e5··on Why and how we’re migrating many of our servers from Linux to the BSDs
Awesome, you are kind of describing my dream job. Any particular hobby projects you are willing to share? I'm working on something myself trying to use eBPF/XDP offloading for a particular protocol
ab71e5··on Why and how we’re migrating many of our servers from Linux to the BSDs
What sort of projects did you do to get into network stack and driver development on BSD?
ab71e5··on What is an SBAT and why does everyone suddenly care
Why? You could just copy the binary and signature to your EFI partition from Windows? What am I missing here?
ab71e5··on What is an SBAT and why does everyone suddenly care
> Microsoft's stated intention was that Windows Update would only apply the SBAT update to systems that were Windows-only, and any dual-boot setups would instead be left vulnerable to attack until the installed distro updated its grub and shipped an SBAT update itself.

I wonder what went wrong here? If you would read the EFI boot order it would clearly say to boot shim first? Or were these dual boot setups where the user would use the firmware menu to select linux or windows?

Anyway this comes at a time when I want to install linux on my work PC, since it has two nvme slots I think I'll go with installing it on a completely separate drive. Would have not prevented this issue though, which seems a legitimate fix from microsoft, just bad communication.

ab71e5··on So you want to build an embedded Linux system?
This is amazing, thanks for the breakdown. I guess this article makes it seem easier than it is. I will stick to SoM for linux for my projects for now but definitely going to try some stm32g0 and the like custom boards
ab71e5··on So you want to build an embedded Linux system?
Thanks! Yes I should probably start with something simpler, I have a tendency to want to skip ahead to the good stuff
ab71e5··on So you want to build an embedded Linux system?
Question for anyone who has done something similar : how feasible would the hardware part be for someone who has some basic electronic / breadboarding knowledge but no pcb design experience? Besides this excellent article what would be a good resource to learn to do something like this myself?
ab71e5··on NanoKVM: Affordable, Multifunctional, Nano RISC-V IP-KVM
So basically what would be a BMC on a server? I saw that the SFF PC I use as a server has intel Active Management support, I am thinking to just use this if I can get it to work.
ab71e5··on The KeePassXC Kerfuffle
But in Debian you could download the source package and patch it yourself should you want to as well right?
ab71e5··on Cardio fitness is a strong, consistent predictor of morbidity and mortality
I've heard the same thing, but for cycling. However I wonder if that is not mostly for people who train much more than a normal person, like a pro or your ultra marathon friends.

I understood the idea was that by running / cycling mostly in zone 2, you can put in more distance / time as you can recover more easily. It would not be possible to bike 30 hours in a week in zone 3, you would trash yourself.

But for someone like me, biking like 6-8 hours a week, I could easily do a lot of higher intensity, recovery time is not a bottleneck, other obligations in life are. So I really wonder if that still applies if you're only running / biking a few hours per week?

ab71e5··on Most dating apps sell and share users' personal data
Been out of the dating scene quite a while, but for those who are not, has the 'old school' way of meeting people and asking a phone number etc. become harder now? Do people only want to use dating apps for that purpose now?
ab71e5··on Study puts fermented foods, not fire, as pivotal moment in human brain growth
One that's very easy to make is bread kvass : basically just toasted bread, sugar and some yeast, either sourdough starter or regular bread yeast. It kinda tastes like a weak wheat beer. I assume with some hops it would taste even more like beer.
ab71e5··on Children need risk, fear, and excitement in play
You don't need to move to these specific places in the Netherlands, in pretty much any city/suburb or town over ~3000 or something people you will have everything you need within safe biking distance, including a train or bus station to get around further.
ab71e5··on Responses to unicycling
Noticed this too, there is some rational annoyance with 'impeding traffic' (perceived or actual) or breaking rules but the impact there is so small that it doesn't explain the negative response. I've had people literally threaten to kill me for making them make a minimal adjustment to drive around me?

My theories about this:

* A cyclist forces the driver to go out of 'auto pilot' and actively think about driving for a few seconds, which annoys people disproportionately

* Cyclists represent a sort of 'others' that we project all kinds of negative feelings on.

* Cycling for transportation in North America is only recently taken seriously and this can be used to blame them for any kind of new societal changes that are perceived negatively (liberalism, inflation, political correctness, higher taxes).

ab71e5··on Not knowing the /proc file system
Yeah it should be something like

    char fname[BUFSIZE];
Also better to pass that in as a variable I don't think you can return a char array allocated on the stack like that
ab71e5··on Introduction to Linux interfaces for virtual networking (2018)
Never heard about netdevsim before, not too much documentation shows up in a quick search though. Seems like a tool for control plane solution development in the absence of a nic / driver that supports hardware offloading?
ab71e5··on Introduction to Immutable Linux Systems
Same thing for OpenWrt I think. I believe it works by using a squashfs and tmpfs and using overlayfs to overlay the tmpfs on top of the r/o filesystem. But I'm not sure that fits the definition used here for immutable OS:

> We could say that a Linux LIVE-CD is immutable, because every time you boot it, you get the exact same programs running, and you can't change anything as the disk media is read only. But while the LIVE-CD is running, you can make changes to it, you can create files and directories, install packages, it's not stuck in an immutable state.

ab71e5··on Switching to Fedora Silverblue
> That is, sudo pacman -S some-package may lead to problems, so it's recommended to use sudo pacman -Syu some-package instead (see this section for more details).

I think `pacman -S some-package` is fine, it's `pacman -Sy some-package` that could be a problem.

ab71e5··on Indiana manipulated report on Amazon worker’s death, investigation says
That's what I thought.

Maybe it is about the state showing what it could do for Amazon in the future, should they build their HQ there? Or maybe it is more about saving the image of the company then the actual fine?

ab71e5··on VxWorks now with C++17 and Rust support, alongside Ada and SPARK
Management and control plane software for radios. Like others said, not that much VxWorks specific knowledge required just like another RTOS.
ab71e5··on Tasty Seaweed Reduces Cows’ Methane Emissions by 99%
The UN report [1] says that if the world population switches to a fully plant-based diet by 2050, accounting for the expected growth in population, we would actually use less land and less water as we do now. So we could in terms of land and water use. Or do you mean some other reason why this would be impossible?
