The problem I always have with locals (in kernel code written in C) is that the compiler tends to optimize them away, and gdb can't find them. So I end up having to read the assembly and try to figure out where values in various regis

I just disable colors wherever I can. And curse the UEFI shell and its dark-blue-on-black whenever I'm forced to use it..

She was remarkably untouched by the world wars, as she lived her entire life in the USA, and my grandfather was in college and was not drafted into WW1, and was too old for WWII (Nor did she have any sons). In fact, WWII was probably a posi

My grandmother was born in 1901 and passed away in 1995. It was an amazing span of years to be alive, in terms of progress. She saw computers go from room-size to PCs. She saw the birth of aviation and people walk on the moon. She saw el

In terms of C, that's one reason I prefer the BSD coding style: int foo(void) { } vs the Linux coding style: int foo(void) { } The BSD style allows me to find function definitions using git grep ^foo.

When I moved a few years ago into Verizon Fios territory, I was excited about the 1Gb/s upload speed vs the 20Mb/s I had with my previous cable provider. I WFH, and upload a lot of kernels and entire OS images to our test servers

Your pattern would not work for me, and a few other the other commenters on this thread, because we value sleep tracking. I had an Android Wear watch years ago (2016?) that started with 36hr battery life and did great sleep tracking and fit

I replaced my first Garmin (640M) at roughly 5 years old due to physical damage (it got mangled badly enough that the part of the case that holds the band on broke off), and it was still getting roughly the same battery life as it did when

Airplay doesn't qualify as "convenient" for me. First is the frustration of even getting it to work, and second if I have a phone or mac open, I'll ignore the TV and get sucked into work instead of relaxing.

They are also a huge battery drain. I wish Garmin put the effort into their iOS app that they did with their Android so as to be able to filter notifications by app. Eg, I want iMessage notifications on my wrist, but I could care less abo

That's what I've gotten used to from my Garmin. It has a claimed 2 weeks of life, and I charge it once a week. I pointed out the 48hr life because I loved the MS Band, and I can't think of anything it didn't do that any

If the feature detects signs of pulselessness, infrared and red lights also turn on, looking for additional signs of a pulse, while the motion sensor starts to look for movement. An AI-based algorithm brings together the pulse and movement

" all-day battery life " Ugh, Apple really has lowered expectations. In order to switch from my Garmin, I'd want at least a week.. Even my MS Band from 10 years ago had 48hrs of battery life.

The only reason I'd want to use a Patreon app over their website would be to play creator's videos on a large screen. As far as I can tell, they don't have an AppleTV app. This, TBH, is why I've never supported a creato

Its funny, because this is the exact opposite of how some cannabis dispensaries operate in Washington DC. It is illegal to sell cannabis there, but not to posses or to gift it. So you buy a $50 QR code that lets you access "digital a

The most interesting bit about this article for me is the "transition time" to get the power needed use AVX-256 or AVX-512 which is present on Intel, but not AMD zen4/zen5. It explains some behavior that I saw years ago when

Acquire some special skill, don’t be a fungible software engineer. Learn C and contribute to an OS kernel. Learn FORTRAN or COBOL and learn to read and maintain ancient codebases. Domain specific jobs tend to be much more rare, but also

I'm pretty sure it is because when Linus ported Linux from x86 to the DEC Alpha in the early 90s, he used the DEC OSF/1 syscall numbers (and error numbers) so that he could bootstrap the Linux kernel from an OSF/1 userland.
