The general purpose quantum magic is Grover's algorith https://en.m.wikipedia.org/wiki/Grover%27s_algorithm.

Grover's algorithm is a general solution to the search problem. Given an arbitrary (computable) function f: X -> Y, and a desired value y in the codomain, find a value x such f(x) = y. For the sake of simplicity, assume that x is unique (although a Grover's algorithm can be extenef to not have this constraint).

Let N be the size of the domain X. On a classical computer, without any additional information, the optimal solution is to simply iterate through X trying inputs until you find the correct one. On average you will need to evaluate f on half the possible inputs, which is N/2. In the worst case, you need to try all N.

Using Grover's algorithm, you can solve the problem with only sqrt(N) invocations of f, which is a quadratic speed up compared with classical computers.

Applying this to encryption keys: for a keylenth of n, we have 2^n possible keys. Classically speaking, you would need to try decrypting (2^n)/2 = 2^(n-1) times. But with Grover's algorithm, you can find the correct key after decrypting judt sqrt(2^n) = 2^(n/2) times, which is the classical worst case for a key of half the length. Note that this is still exponential in the size of the key, so is not a fundamental game changer.

This has nothing to do with prime factoring or the discrete log problem. Those have even better quantum algorithms (Shor's) that can solve them in polynomial time, which would be a major game changer if they ever become practical.

Can we really call the car an "invention"? After all, both the wheel and the steam engine already existed.

Those techniques were already invented and in-use long beforehand.
Even that is saying too much.

It's vague, nontechnical and invites follow-up questions, and implies you're the type who'll tamper with the aircraft in flight.

If you are trying to maximize port utilization, sometimes the exact instruction ordering can make a big difference. Compilers often want to "hoist" loads to the top, which can sometimes reduce performance. And sometimes you need a particular addressing mode to avoid a bottleneck.

In general, kierank is right: if you want to full optimize something, and you know what you want the actual code to look like, just write it in assembly. Nothing else gives you full control over loads and stores, and anything else leaves you at the mercy of some future compiler "optimization" stepping in to defeat you.

Yep, that's right. The "mini player" on Windows has exactly the same problem. Its a big box of 200x100~ pixels or so and it doesnt include a volume control, you have to exit the mini player. I do not understand the reasoning of such decisions, really. It maybe looks cute but It's pretty useless.

It seems Mark Pizzolato was at the time the primary maintainer and recent contributor (by a large margin) (https://groups.io/g/simh/message/1501).

Mark made a change to how the virtual disk system worked that broke an esoteric use case (using dd to image multiple disk images to an SD, without an actual file system). The user didn't want to use a workaround (specifying the transfer size in the dd command), and proceeded to use twitter to get people to harass Mark. (https://www.bentasker.co.uk/posts/blog/the-internet/toxicity...)

Mark got sick of the harrasment and decided to take his toys and go home.

It seems like a win for most use cases, however it's a major setback for cpu-heavy use cases too:

- the 5$/month subscription only includes 30 million milliseconds when it was previously including 500 million (10 million invocations of up to 50ms cpu time each)

- for longer-running workers, the cost goes up 13x (!!!) to $0.072/hour for CPU time compared to $0.0056/hour in previous Unbound plan (advertised as GB-sec but each worker had 128MB so 1/8th)

My apologies. I was just trying to summarize the op’s contention about what’s transpired with Facebook there. I have no reason to doubt what you say is mostly true, but do you think that some of the general Buddhist population, beyond the Junta/leadership/dictatorship, had anti-Muslim/Rohingya sentiment before Facebook was widely available and so it was those voices who were amplified when Facebook’s growth accelerated in the country? The primary person the article cites was a Buddhist monk from what I understand.
> Searching for already-paired bluetooth devices still sends a bluetooth frame with your bluetooth MAC address, (which has to be consistent, because that's how bluetooth devices identify each other).

It doesn't have to be readable by third parties. Given that the devices are already paired, it's perfectly feasible for that frame to be encrypted gibberish that only the other device can understand.

Seems like the real utility of this technique will be as a way to vastly improve the temporal stability with a variety of generative video techniques. For example, if you are trying to use a video as a base for a new generative video: Take the first frame of your video and run it through SD with the control net of your choice. Then take that initial image and run it through this process to generate a new base model and then use that to generate your second frame. Now you can use that second frame to feed back into your model and rinse and repeat, always using the past few frames to inform the latest.

This may change in future, e.g. by enough people turning to formal verification.

Does it mean that it is unsafe? In that case notion of safety seems to be destroyed.

It sounds bad but it does still sound primarily like neglect and not some kind of genuine active involvement, as I hear frequently suggested.
Is your inter-machine messaging asynchronous and is it possible for one of your machines to crash?
Over the short term.

My concern is that people are consciously avoiding slacking off during the trial period but will later return to their long-run productivity once they grow accustomed to 32 hour weeks.

The other concern I have with these studies, is that these companies appear to be overstaffed in the first place. While we all have some amount of slack during our days, I doubt anyone in my team has enough slack available to get the same amount of work done in 4 days.

I’d want to see a long term study that involves lean companies and people in leas-creative roles before buying into the hype.
To this day there is no answer to the iPhone. Android's answer is "copy, but if we have to choose between quality/sw-support/security and low-price, the default choice is the second".

But make no mistake. If someone could leapfrog Apple today (just like they did leapfrog the whole industry back then), the iPhone industry would crumble overnight. But you need that idea, that upfront capital, and that marketing budget...

Huh, I’d put both of those in the top ten, and Guardians 2 might be #1. Most of the others are kinda cinematically flat, and any time they have any kind of political themes (which is a lot of the time, actually!) it’s always frustrating because they don’t follow through (too risky, I guess?), which those two mostly avoid. Also, the pop music thing is kinda a cop-out, but damn, at least it’s better than almost-impossible-to-remember temp-music copycats in the rest.

I can see how someone who preferred the tone of the earlier films would dislike those two, though. I’m personally not thrilled that their influence has spread to the rest of the franchise as much as it has—just because that tone works well in some of them, doesn’t mean they should all be like that, and with so many films it’s much nicer to have more variety, but I guess the producers are following the money.

At least we can all agree Thor 2 is last. Thought I’d allow arguments for Avengers 2.

[edit] wait, Thor 3 or 4? 4 is the closest I’ve felt to the first time I watched Attack of the Clones, and it wasn’t even because of Natalie Portman. Yes, that one’s bad.

The example given wasn't a simple cast of a value, and definitely not an implicit coercion. The example is more like C-style type punning where you explicitly cast a pointer to the value and then write through the dereferenced pointer.

I don't doubt that there are niches where such explicit type coercion patterns are common in Go and susceptible to mistakes, but I doubt usage of constant identifiers is such a niche.

Rust is currently the standard bearer for strong, static type safety, and it even has both the enum types and pattern matching construct which Go lacks. AFAIU, you can use unsafe{} Rust code to perform a similar type punning trick, successfully assigning an invalid value to an enum object. I don't know if Rust's code generator always inserts runtime validity checks in match statements on an enum value without a catchall/default case, but certainly it's possible for Rust code to have an explicit if/else chain that at compile time appears comprehensive but which would neither panic nor produce the expected behavior. Does that mean Rust programmers shouldn't rely on Rust's static typing, instead always adding explicit code to handle unknown/invalid enum values?

Maybe the assertion that Go code should have such checks is more reasonable than for Rust code, but you haven't explained how. At least to me, the simplest, minimal code to achieve the subversion in both Go and Rust seems similarly stilted and similarly unlikely to be written by mistake. (To be clear, the context of this subthread as I understand it assumes the interface method hack, the subversion of which requires the type punning.)

Yes it is important to have validation for anything coming in from outside (json, the database, etc). This is done by creating a map with the valid enum values and checking at runtime. This compile time solution wouldn't have worked for validating enums sent in json anyway, it's purely a defense mechanism against library users trying to cast arbitrary values to a package type.

Often, it's best practice to store time in both epoch (UTC) format and the actual time zone when the transaction/event occurred. Epoch time can be the universal truth, used for business rules and it can be displayed in whatever time zone the user prefers. The event's actual time zone can be used for analytics and other research purposes, but for critical business decisions or rules.
I do not quite understand the last figure for the relaxed avl tree. For the 100 % lookup (rightmost) the TL2 algo should scale linearly with the number of threads. For read-only transactions, TL2 needs to sample the global version, then for all reads make sure the local version is less than or equal to the sampled version. given this, it is difficult to understand why the graph is sub linear and that TL2 is not as fast as the other STM implementations.
Classic VW bugs famously have an issue with their clutch cable- it will eventually break, causing the clutch to unexpectently engage. If you happened to be waiting at a red light the car could lurch into the intersection if you didn't have your foot strongly on the brake. (this happened to my dad, no injury, just scary).

So the controls have to be reliable and robust. It will be easier to demonstrate this if the system is simple. So I think we would prefer software to not be involved in safety systems, but if it must be done you need to go to extraordinary measures to demonstrate its safety.

How you do this for something like full self driving where there is a trained system involved (i.e., that you don't know how it works) I have no idea.
Ask HN: Autistic? Have kids with ASD? Can we chat tomorrow?
Hi HN!

I’m working on a thing with a few folks this weekend at Inception Studio [0], and it’s specifically focused on building tooling to help people with autism navigate conversations and the world.

If you are autistic, or if you have kids or family that are autistic, would you or them be willing to chat with me tomorrow (Saturday 9/30) for a half hour or so?

If so, I’d buy you beer/coffee or pizza or good will and karma. <3
