tons of people use linktree on social media sites like Instagram or TikTok where linking to things is particularly hard (i.e. links are not clickable anywhere except the one link slot in your bio). Sites like linktree let people make a litt

I love maps on the watch but it is incredibly annoying that you can't activate the screen (ie raise to wake) while keeping your hands on the wheel.

Yes!!! Why won't it just tell me what my exit is? I don't care if it's 100 miles away, just tell me what it is now so I can be sure I don't miss it. Messages like "continue for 10 miles" covey absolutely no use

Always love hobby operating systems which leave UNIX and POSIX behind. It's really a shame that we're slowly converging on POSIX being the basis of _all_ operating systems since it forces some bizarre and undesirable design decisi

I had to do something similar for building out an automated hardware test cluster of ARM devices for OS testing. We settled on a bunch of varied SBCs (we were less concerned with peripherals than we were different SoC features/configs)

100%. I don't know where the seemingly common believe that being a kid is easy. It's simple in the sense that you have no choices to make, but that lack of choice is exactly what makes it so difficult. Being an adult is so much ea

I think HN, as a largely technical audience, should see the clear problem with that query. Of course search engines certain results when you use terms like "big tech". It's a term that is largely used by conservative groups i

Being able to plug your ears and call a field apolitical is a matter of your position in society or in your sub community. There's the joke that goes "what are the two sexes? Male and political", and it really does have a gra

Why does the author assume we _want_ the law to be well-defined? Law makers frequently don't actually know what they mean and it would simply take too long (and would be too fraught) to try and actually spell out what they mean. This,

Neat! Looks like it's very much in its early stages (no concurrent execution/threads yet) but it's so great to see FOSS digital design work in an industry dominated by huge players

Can I ask an office hours type question? I worked on a very similar (if not identical lol) project at a job once upon a time and the biggest problem I had (and one that I never really solved well) was recovering call stacks from trace data.

Ha, this was my experience as well when getting into hardware after spending forever in software. It's SO amazing being able to just shoot a program through simulation and then look at the waveform to see how an instruction propagates

haha I remember talking to one of the engineers on the enterprise management team at WWDC back in 2015 and he was surprised that anyone used it at all. It really did work well and it did its job.

It's generally good to use symmetric cryptography wherever possible because it usually (!) is faster and simpler. More complex crypto systems provide interesting properties but if you can pull off whatever you're doing without it,

Not to mention OCSP stapling provides a revocation escape hatch that allows a certificate to continue to be used even after it has been revoked and the revocation has been streamed to all relevant OCSP servers.

I feel like the kernel live locking in low memory environments should be treated as a bug and not something we try to solve using swap. Like...if the OOM killer can't free memory under low memory constraints, something has gone serious
203.
by Sirened 4y ago
Yep! The idea of "free memory" largely doesn't exist in modern operating systems. We haven't gotten to the point of power gating DRAMs (have we?), so we're always paying the cost of the DRAM all the time. As such, n

I think it's less a criticism of trying to solve problems in hardware vs the _kinds_ of problems they're focusing on. While CHERI is, from a pure theory standpoint, something that is perfectly avoidable with proper programs (i.e.

It absolutely can! On ARM you can just enter a block entree in a non-leaf page table to allocate an entire block of physically contiguous memory in a single TLB entry. From the ARM docs [1], any CPU supporting 16K translation granules will

This isn't a criticism of Linux itself or the GPL, it's a criticism of the fact that both people replying to me and vendors treat Linux as if it's the only operating system worth caring about. Support for Linux is neat but it
