"The only hard part requiring serialized synchronization is the carry bit, across compute nodes." I don't think that's the only hard part. Branches, for instance, are rough. "What are the advantages? Predictabili

I'd like to see qeternity chime in on this, since it's their space, but as market that is too rigid can't actually provide sufficient liquidity to users to function as an effective market. Let's say you're comparing

I think you could account for hold-out by having the resolve window be longer than the trade-insert window, at least to an extent. The trade-insert window can't be too long, or it would leave lots of room for regret, like people who

Pleasantly, good speed controllers already have low-voltage cutoffs. VESC has it, for instance. I believe it’s configurable for cell count, sag, etc.

I'd suggest a Raspberry Pi 3B+ (can you even buy an original Pi?), with more than 3x the single-threaded performance of an original Pi. I'd wager comparable single-threaded raw performance to the N270, a 10 year old chip at this

Funny.... I also just dug an Eee 901 out of a box (it used to run Windows Home Server). Honestly, just grab a Raspberry Pi for your retro gaming console. It almost certainly does the job better, and the power usage difference will pay fo

There was one of these tooling around the campsites at Le Mans a few years ago (probably there every year). Lamborghinis, Ferraris, TVRs. No. The R5 Turbo got all of the crowds. It was awesome. Nonetheless, I haven’t seen a Renault in th

Unfortunately, that sentiment, wielded as a shield by the ambitious, papers a veneer of virtue over the callous disregard of cutting corners with other people's lives. The reality is that careful development is expensive . If Uber an

I think the NTSB examined the crash, so there's at least some federal oversight.

Well, to be fair, if someone in the US is able to find a running Renault that can go faster than 30mph under its own power, it's pretty exceptional. I think that Tesla's response is tone-deaf and ill-advised. I'm not present

First off, I agree that, in principle, a backdoor is a backdoor, and vulnerable is vulnerable, period. However, there's A5/3 weak, where everyone can hack it, and there's Dual_EC_DRBG, where the right secret is necessary.

In general, I agree. However, as a mild counterpoint, I present Dual_EC_DRBG, where the NSA inserted a private kleptographic backdoor into the standard via the conveniently provided P and Q points. Brilliantly awful. You realize, of course,

There's a mild difference, in that China has been kidnapping people to take them back to China, where they can be coerced mercilessly. Because we have Constitutional protections in the US, we sent people to other countries... where th

From the report “NHTSA’s crash reconstruction indicates that the tractor trailer should have been visible to the Tesla driver for at least seven seconds prior to impact.” Unless someone is operating trucks with adaptive optical camouflage,

I think that the S and X have three forward-looking cameras center-mounted. Without a binocular baseline with which to establish distance, ranging of on-center obstructions could be difficult. Even if an edge is visible, the frame-to-fram

I'd expect Monte Carlo methods to be used in a number of cases that have deterministic time envelopes for evaluation. Randomized selection and evaluation can be incredibly effective. They also resist degenerate structured input vulne

I agree with you. I think the statement (ish) “don’t use if/else, use return” deserves some qualification, and one natural place to use it is for errors. When people start dropping returns all over massive multi-screen branching and lo

I think there's a lot of value to returning early out of functions when you hit an error condition. There's not much reason to go further if you're just completely hosed. (e.g. malformed arguments). However, I don't th

I'm responding to the assertion: "The OS should use all available RAM it practically can for things like cache. Not the applications." Applied absolutely, it results in deeply sub-optimal behavior in a large number of cases.

That may not actually be a practical approach to the problem. Years (and jobs) ago, we rolled significant caching into Vegas (video editor), allowing the app to take up 8GB of RAM in cached frames, even on 32-bit builds. There was no way

By the way, given sufficient demonstrated counting ability and savvy, I would be willing to invest in a blackjack team. And it's worth noting that people do invest in currency. It is not merely an exchange vehicle.
