There are two different kinds of trust: trust that you're a legitimate person with good intentions, and trust that you're competent. A university or corporate e-mail address helps with the former: even if the individual doesn&#x27

Except, from that email chain, it turns out that some of the bad code did make it into the stable branch. Clearly, they weren't keeping very close tabs on their bad code's progress through the system.

From GKH's response, which you linked: They obviously were _NOT_ created by a static analysis tool that is of any intelligence, as they all are the result of totally different patterns, and all of which are obviously not

GKH, in that email thread, did find commits that made it to production; most likely the authors just weren't following up very closely.

Dr. Wellerstein, the book's author, has a great blog at http://blog.nuclearsecrecy.com/ where posts some informal write-ups and cool source finds. Some of my favorite posts: On the changing and unclear knowledge of Tru

Of course most people aren't that Machiavellian. That's why you hire professional PR people, who a "spokesperson" presumably is. Their job is to be that cool cucumber when things go wrong.

I was referring to the C++ description as "precisely right". Though note from those emails that Rust-in-the-kernel will also require a rework of a lot of stdlib stuff, especially if they want to use the kernel allocator; it'l

IMO his rage posts usually still had great insightful points (cf "we do not break userspace"). The rage part was maybe unnecessary, but it wasn't the entire content of the emails.

Sustainability is orthogonal to the geographic patterns of development - it's always going to be more efficient (even in environmental impact!) to cluster around resources and transportation.

It is indeed in the earlier benchmarks, but: * It's not in the later ones * You present TurboFan performance as the speed of JavaScript. e.g. your tables present JavaScript with Ignition as ~40x slower than JavaScript in certain test

Yeah, that integrated offering is a great market differentiator. Still a much higher bar than the basic competence that SpaceX has had to display to eat everyone else's lunch.

The space launch industry was uniquely dysfunctional; SpaceX could get away with starting near the bottom of the learning curve. Tesla, by contrast, is up against companies that build products at large scales in a thick market while competi

Yes. e.g. the California High Speed Rail is a partisan issue in California politics, and generally Republicans are suspicious of commuter and high-speed rail as wasteful environmentalism.

Lots of the ARM-related changes are cleanups/modernization of code that the Apple support uses, e.g. https://git.kernel.org/pub/scm/linux/kernel/git/soc/soc.git/... Cyclades removal w

This particular treatment does not affect the germ line. i.e. it corrects the defect in the patient, but they can still pass it on to their children, who would be (malaria-protected) carriers.

It wasn't that "soldiers won't last longer" - it was that the division wouldn't last longer. Soviet doctrine solved the problem of maintaining fast advance with fragile men and equipment by subjecting individual u

That is part of the dynamic. More importantly, though, a narrow decision makes a broad decision easier. If some justices think the code isn't copyrightable, they can increase their voting power by agreeing to set a less sweeping preced

It would be absolutely helpful to astronomy and planetary science research. We have never in history looked at extrasolar material up close. And if it is indeed relatively cheap, it doesn't need to be "fundamental".

You know you've fucked up when you have to remove features from the spec (which they did in YAML 1.2).

Interestingly, that westward reach of CET is an artifact of WWII. France and the Benelux countries changed time zone in 1940 under German occupation, and Spain changed time zone as a symbol of fascist solidarity.

YAML had a worse example, once. For the ease of entering time units YAML 1.1 parsed any set of two digits, separated by colons, as a number in sexagesimal (base 60). So 1:11:00 would parse to the integer 4260, as in 1 hour and 11 minutes eq

I'm not "rationalizing", and neither are you. You're arguing that it's not enough to make a correct implementation, but that it's also important to break compatibility with incorrect implementations. I'm a

Two pointer dereferences are slower than one - got to read from the top-level array, then use the pointer to read from the individual string. This way you can figure out the address of the string with about four very cheap instructions and
