One interesting feature of signed vs unsigned in languages where signed overflow is undefined is that signed numbers _behave_ like mathematical integers, whereas unsigned integers (because overflow is valid behavior) _do not_ behave like mathematical integers. For example: if you write a loop that sums numbers from 1 to N, for signed integers the compiler can assume the expression won’t overflow and emit the standard mathematical closed form, because unsigned can overflow it has to account for this and use a different closed form (if one exists for the unsigned case). IMO unsigned should only be used when you want to manipulate the bits of an integer and not the integer itself, but C and C++ fight you when you try to do this because of how ingrained size_t is.

I personally use a 3x6 Corne for non-gaming tasks. I would recommend it for anyone that uses a keyboard for more than a few hours a day to preemptively reduce the risk of RSI, especially programmers. The small layout and tenting reduce wrist and finger strain significantly, to the point where when I have to use a regular keyboard at work I can quickly notice the pain in my right pinky. If you want something with curved key wells the Dactyl Cygnus is a Corne-like option. I haven’t bothered to try anything smaller since I don’t see the point (for non-steno), as all keys on a 3x6 are within 1u of the home row.

I largely agree. Split, ortho/columnar, and tenting is 90% of the strain benefits. The biggest benefit from layout change (for programmers at least) is moving symbols and numbers to a layer where they share positions with alpha keys so you don’t have to extend to type them. Any benefit I could imagine from switching alpha layouts (more even utilization between left and right hand for typing prose) is mitigated by the switching cost when trying to use a normal computer.

There are momentum indices. Momentum is actually a strange phenomenon from the perspective of the efficient market hypothesis because it does not have an obvious risk to balance its premium compared to other empirical factors.

Immigration is not a solution to low fertility. It might be a solution to labor being expensive, particularly if you’re a capitalist, but it doesn’t solve the problem of low fertility among a native population.

They can restrict it to US citizens only: just do KYC and enforce it. Any citizen exporting ITAR capabilities would be committing a felony.

I think it is inevitable that more capable models will require export controls, KYC, background checks, verification of credentials, etc. Even if you don’t buy Anthropic’s marketing of their current models, there is a future where models are capable of developing chemical weapons, biological weapons, cyber weapons, etc. which are genuine security threats governments will care about controlling and preventing. Maybe this prevents big commercial labs from developing more capable models until they figure out appropriate safeguards, but this is a good thing, a world where you can ask an LLM for an airborne rabies genome and it will simply produce it for you is not a world we should want to live in.

You can probably eliminate the switch bounds check by making the default case execute __builtin_unreachable(). The switch version is safe for non-conforming opcodes where the computed goto version invokes UB.

People have built entire careers shipping garbage, now they can ship 10x more garbage and to them that’s progress.

The STL is not good if you want performance or predictable behavior. The issue is in the specification and the requirements placed on certain algorithms and data structures. It’s easy to beat unordered_map for example with an open addressing hash map, small vector optimization can’t be implemented in vector due to standard requirements, etc.

The consumer economy only exists to extract value from common people and funnel it up the wealth ladder. If robots and AI take over all the production, you don’t need a consumer economy, the robots produce and their output directly goes to the top. The rest of us are left to starve.

This is a useful lesson! Tuning an allocator for a single application reduces to optimizing for that application’s empirical allocation patterns (sizes, lifetimes, access, usage).

I’m not exactly sure what you’re getting at, but I think I’ve had a similar question: why don’t HDLs have language elements more representative of what digital circuits are constructed from, namely synchronous and asynchronous circuits, rather than imperative input triggered blocks (processes IIRC, it’s been a while)?

I always thought it was confusing to design a circuit mentally (or on paper) out of things like muxes, encoders, flip flops, etc. and not have language-level elements to represent these things (without defining your own components obviously).

I remember looking this up, and I believe it’s because the languages were originally designed for simulation and verification, and there are things you might want to do in a simulation/verification language for testing that are outside of what the hardware can do. Mixing the two is confusing IMO, but clearly demarcating the hardware-realizable subset of the language would be better than the current state.

Maybe, another possibility is the frontier providers change their pricing terms to try to capture more of the value once a sufficient number of people’s skills have atrophied. For example: 20% of the revenue of all products built with $AI_SERVICE. For someone several years out of practice they may have no other option.

Insiders bring information to a market. Intelligent analysis and prediction also does, but obviously insiders have special information they are incentivized to bring to the market. Most people placing these bets are simply gambling, insiders and analysts at least have rational reasons for placing bets and add information to the market.

This is a fundamental misunderstanding of why index funds are effective. Being over invested into U.S. equities is a risk if you hold outsized U.S. index funds (esp. if you have a large allocation in the S&P500, you do not own the market portfolio), but there are other risks being invested into foreign equities as a U.S. investor.

This will remain the case until we have another transformer-level leap in ML technology. I don’t expect such an advancement to be openly published when it is discovered.

There is a fan project that has revived the servers. It’s hard to get full matches but can still be played at least. It’s called BLRevive, there’s a Discord for it. IMO the only bad thing is it’s based on the post-PS4 update where the devs console-fied the game.
