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 short message and then move on to different activities, and engaging AVX512 doesn't actually pay off in reality. OpenSSL is optimized to produce the biggest number from `openssl speed` so of course in that light it makes perfect sense to enable AVX512. But if you're trying to use these libraries in realistic workloads you will begin to appreciate the boringssl approach.

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 want to punch useless holes in the earth, Elon Musk is your man without a doubt.

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 great idea and they should absolutely expand this regulation to cars.

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/...

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 behave like even bigger jackholes than usual. https://psyarxiv.com/nxw2k "... public health research might be best served by shifting focus to risk elimination rather than harm mitigation."

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 last year’s [2018] e-bike sales stood at slightly over a quarter million units; some 251,500 to be more precise. This accounts for a big 14.3 percent growth compared to the total of the year before. It makes electric bicycles by far the biggest category of the Belgian market with a market share that stands at close to 50 percent."

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.
