78C is not a really objectionable temperature for a CPU, if that's really the on-die temperature. Usually thermal protections are set to 90C.

You know I think that cloudflare blog post is a great example of the engineering approach behind boringssl. It's optimized for actual workloads, where you decrypt or authenticate a…

Related saying: a scientist can write a FORTRAN program in any language.

In the marketing photo, which is obviously a composite rendering of a product that does not exist, this piece of crap is stopped picking up some jerk in an SFMTA bus stop. Let's ho…

No, it's just a lot smaller. A 12-foot-wide tunnel is, shockingly, much cheaper than a 21-foot-wide tunnel. It also has essentially zero capacity, much like a hyperloop. If you wan…

"That statement in the article makes no sense in the context of other stated facts in the article." You read some unsupported claims on a fan service blog for a pump-and-dump stock…

San Diego actually passed an ordinance requiring scooters to geofence speed limits of 8MPH in many areas. See https://www.kpbs.org/news/2019/jul/01/dockless-scooter-regul... It's a…

E-scooters instantly dominated the market share of shared micromobility when they debuted in the USA in 2018. https://usa.streetsblog.org/wp-content/uploads/sites/5/2019/...

Yeah but it's 2020 and I decided that just because people are displaying their own ignorance on the Internet doesn't impute upon me the duty to adjust their attitudes. If two fuckw…

Sure, if you don't know what the term "market share" means then your comment makes perfect sense.

Please go find out the definition of "market share".

The evidence in favor of wearing a helmet while in a car is just as strong, but nobody is up here advocating for that. By the way, helmets on bicyclists tend to make car drivers be…

I hate that HN is a place where the ignorant simply flaunt their ignorance instead of trying to inform themselves. "According to the Velofollies survey as well as other sources las…

I have a suspicion that our industry harbors an above-average number of bicyclists.

You're welcome to wear whatever you want while riding your illegal whatever-you-call-it. Don't scold the rest of us.

You need a special license for mopeds in many jurisdictions, they weigh 100+ pounds, double what an e-bike weighs, and because of the fuel system you can't really just carry it up …

Helmets are for sports. Ebikes have a ~50% market share in Belgium where approximately nobody wears a helmet ever. It's really not an issue.

I'm not sure what the point is, actually. The variety of things that can go wrong with them is astonishing. For one thing, among many others, BMC cards will power-cap the max clock…

It's adorable that you think batteries and dual PSUs are something that makes a node more reliable, rather than less reliable.

"no real need to make your implementation more complicated than a single array" That's our industry in a nutshell. Our computers, instead of becoming more capable over time, can ba…

POSIX threads can be individually named. They inherit the name of their creator if you don't set one.

That presupposes that you can start with a big pile of bad APIs and somehow incrementally approach something worth having. That's not consistent with my experience. In my experienc…

Well, estimates I can google up at the moment put the Pb-acid worldwide market at ~$42bn/year and the Li-ion market at ~$40bn/year. The latter is growing much faster but the former…

I think this is an important point. The lithium-ion battery market is _still_ smaller than the lead-acid battery market. This business is still ramping up.

Being a good-enough CPU for terrible software is a bit of a tragic conclusion, in my view.
