Internet Explorer was _better_ than Netscape in the 90-s and the early 2000-s. Microsoft Office (and especially Excel) was just about perfect around 2003, and only degraded since then. I would argue that Office 2003 is still the best offic

Windows NT kernel is a marvel of engineering. It's incredibly flexible, you can build crazy stuff on top of it without having access to its source code. As an example, Parallels had a version of Docker-like containers on WINDOWS in 200

We don't need to move _all_ the people to carpooling to fix the congestion. And remember, the alternative is even worse: buses.

Uber Pool in SF was awesome when it was truly 50% of the cost. But they started hiking up the price (because they could) until it was maybe ~20% less than the full ride. And then COVID happened. > Self driving cars for individuals make t

Waymo is not doing any carpooling optimizations. They're right now a luxury service that is priced above the normal Uber ride prices. This will obviously change in future, once they start a truly mass rollout.

Yes, it is. That's why "affordable" is a bad term. There's also a problem with the way this term is used in practice. It now ended up meaning _subsidized_ housing. An average person would NOT be allowed to buy this housi

Right now the average car occupancy during the rush hour is ~1.5 persons per car. By increasing that to 3-4 people, you can easily double the effective road capacity. This will completely resolve the congestion in the majority of metro area

Yes. This is sometimes called "Carnot tax". The efficiency of any heat engine is bounded by the Carnot cycle. In simplified form, it depends on the temperature differential between the cold and the hot parts. So if your hot part i

Sure. All kinds of people exist. However, properly designed cities like Houston, TX are well-poised to take advantage of self-driving cars. Very soon car ownership won't be necessary even in sparse cities, but with all the advantages o

Yes. Stop toxic urbanization. Prohibit new dense housing and slowly start deconstructing the dense office space. At the same time, promote remote work with tax incentives.

Why? Just make it possible to buy "shares" in a larger battery bank, if you must. Home batteries make total sense for off-grid systems or as a backup power source. But plug-in batteries are not designed to do either.

Not necessarily. Another key here is that the allocation is triggered from the libc, while the main app uses another allocator. These kinds of issues with VM are notoriously tricky to replicate. And the main debugging method is "starin

Andy Lutomirski seems to think that it is a bug: https://lore.kernel.org/all/CALCETrXbj__SFQMzPZhES5y6-sh4np-... I looked at the explanation, and it seems to be at very least plausible. The kernel version bisection als

Thanks! It'd really interesting to try static Hermes with it ( https://github.com/facebook/hermes/tree/static_h ). iOS is braindead and doesn't allow JITs, so regular JavaScript is not a good option

You can trim it quite a bit, and it also compresses quite well. The dependencies are the main issue, there's just a lot of stuff there.

Probably because musl's allocator exposes single newly faulted pages directly to the app. Other allocators tend to pre-allocate multiple pages at a time, so that the race window is narrower.

It got traced to a race condition in munmap() in the kernel. The inefficient musl allocator simply triggers it more easily.

Nope. It's more complicated. The store operation does not need to trigger the fault, it can happen for other reasons. What happens here is a bug in munmap() that happens in another thread. It corrupts the TLB, for a brief instant repla

Yes, that's why Servo is so exciting. It doesn't have to implement _all_ the standards, just a subset that is compatible with the full set. So that if you can develop an app within that subset and have it working in other browsers
