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.
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 hope, for the good of humanity, that a hero emerges to destroy all of these evil toasters.
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.
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 fuckwits on HN want to hang around and tell me that I am using the term "market share" in a wrong or unusual way, when they themselves are the ones who obviously don't know what it means, then let them do it. Eventually the accumulated mass of stupidity recorded on this site will sink it.
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."
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 the stairs and leave it in your kitchen at night.
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 speed of CPUs when a machine is running on only one PSU, which can cause a degradation that's worse than if the machine had just halted. There are a zillion other edge cases like that.
"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 barely keep pace with the increasing naivety of our programmers.
