Yeah, smell and taste aren't really possible. Sound is easy though. For texture you could do force feedback, though latency would be really hard to compensate for. Latency is more critical for touch than vision.

But teleoperation over the Internet isn't the goal here. The reason they're doing teleoperation is to collect data to train for autonomy. The operator stands directly behind the robot during teleoperation. And the goal is to be able to train with only a few demonstrations.

Black Harvard Professor Demoted Under Claudine Gay Responds
Ironically, you're cherry picking from the cherry picking.

It's not just weak studies. Guzey provides multiple examples of demonstrably false statements in the book. There is also evidence of flagrant data manipulation. For example, rather than reproducing a chart from a study, Walker presents a modified chart with the data removed that contradicts the claim he wants to make. This calls into question the quality of the entire book and Walker's integrity as a researcher.

At the same time, I think Guzey's analysis is often brought up in order to dismiss the core claim of the book, which is that most people should be getting more sleep. I'm willing to believe that in fact people should be getting more sleep, and I'm also willing to believe that 90% or more of the scientific research referenced by the book is valid. It's just unfortunate that the book seems to be sloppily (and borderline fraudulently) written and researched.
As a sibling comment implies, it can be a huge issue if the existing codebase tosses out conventions.

It’s underrated since devs mostly do it without thinking about it, but in enough cases you need to double-check the type before running any operation that requires a certain type. Unchecked it will either crash entirely or cause bugs so esoteric that they are very difficult to debug.

I don’t think I’d categorize it as “how Rails suffers without types”, more like “stay away from the edges and you’ll be fine”, but it can still bite you hard if someone mis-steps.

Potentially an acquihire due to exhausting runway? Would align with the idea of a startup funding crunch in the current macro, but only someone with transaction details and willing to violate an NDA (if one exists) would be able to share (if details aren’t going to be made public). Depending on comp, benefits, and infra, it is not outside of the realm of possibility to burn through $32M (Sep 2022 Series B raise) in ~15 months (~$2.1M/month).

I assume you are referring to yourself? It is well know that none of the semiconductor equipment manufacturing is not in Asia due to the PRC. So you get fabs, but not equipment to produce fabs or keep fabs running (all by design, so China doesn't gain much if they take over Korea, Japan, or Taiwan).
SHA256 is something like 30 percent slower than MD5.

I'd suggest using Adler (what zlib does) for a simple and fast checksum. Then that should, one hopes, be painfully obvious to be a bad fit for anything security related.

Most people who do this math are horribly bad at it.

Somehow poor people can afford these cars that cost way more than they make.
When you don't have a need for a cryptographic digest, it's important to think of the channel's bit error distribution in selecting a checksum algorithm.

Different checksum algorithms can provide better error detection for specific channel error models (potentially even with fewer bits). Non-cryptographic checksums are typically designed for various failure models like a burst of corrupt bits, trading off what they do/don't detect to better match detection of corruption in the data they will protect.

For example, if you know that there will be at most one bit flip in your message, a single bit checksum (parity check) is sufficient to identify that an error occurred, regardless of your message size. (Note that this is an illustrative example only, since, typically, messages have a certain number of errors for a certain number of message bits -- the expected number of errors depends on the size of the message.)
I would have (and still do) assume that such feelings are more common in the social sciences. No?

"It has now been a year since a mass exodus of the scientific community from Twitter seemed not just likely but nearly inevitable. The social media platform has gone through a remarkable period of upheaval under the leadership of a billionaire with confusing ideas about ‘freedom of speech’, and we all asked ourselves if it was time to be X-Tweeters?

Scientists of all disciplines were left wondering if the social media platform remained an appropriate place for them to communicate. No reasonable person could feel completely at ease with the nature of some of the content allowed on the platform. Since then, however, the dust has settled … at least a little."
There's a GIF MD5-quine here: https://news.ycombinator.com/item?id=13823704

And a PNG version too: https://news.ycombinator.com/item?id=32956964

But no one has made an exclusively plaintext (ASCII) MD5-quine yet, and I suspect doing so may be impossible given the characteristics of collision blocks.
Another iterative loop-like procedure is search, adjust pattern and/or amount of context, search, adjust pattern and/or amount of context, search, ...

If a program is sluggish, I will notice.

The reason I am searching for a pattern is because there is something I consider meaningful that follows or precedes it. Repeating patterns would generally not be something I am interested in. For example, a repeating pattern such as "httphttphttp". The search I would do would more likely be "http". If for some reason it repeats, then I will see that in the context.

For me, neither grep nor grep clones are as useful as ired. ired will show me the context including the formatting, e.g., spaces, carriage returns. It will print the pattern plus context to the screen exactly as it appears in the file, also in hexdump or formatted hex, like xxd -p.

https://news.ycombinator.com/item?id=38564604

And it will do all this faster than grep -o and nearly as fast as a big, fat grep clone in Rust that spits out coloured text by default, even when ired is in a shell script with multiple pipes and other programs. TBH, neither grep nor grep clones are as flexible; they are IMO not suitable for me, for this type of task. But who knows there may be some other program I do not know about yet.

Significance can be subjective. What is important to me may not be important to someone else, and vice versa. Every user is different. Not every user is using the same hardware. Nor is every user trying to do the exact same things with their computer.

For example, I have tried all the popular UNIX shells. I would not touch zsh with a ten-foot pole. Because I can feel the sluggishness compared to working in dash or NetBSD sh. I want something smaller and lighter. I intentionally use the same shell for interactive and non-interactive use. Because I like the speed. But this is not for everyone. Some folks might like some other shell, like zsh. Because [whatever reasons]. That does not mean zsh is for everyone, either. Personally, I would never try to proclaim that the reasons these folks use zsh are "insignificant". To those users, those reasons are significant. But the size and speed differences still exist, whether any particular user deems them "significant" or not.

Pizza with nutella and strawberries is definitely something you van have in Italy.

My complaint with pizza with ham and pineapple is that it doesn't combo that well. I have no problem with the pineapple, but the combination doesn't enhance the pizza flavor, there are better combos out there.

Also notice that a good quality margherita pizza had an incredible taste thanks to the tomato sauce.

Most tomato sauce I tried in north america are terrible.

One of the properties of shortwave is extensive multi-path propagation. Much of the signal goes the shortest route - and a small amount of it goes all the way around the world and arrives the long route, tens of milliseconds later. And at every point in between too. This is why shortwave AM radio sounds so hollow/resonant/unique - RF echoes stacked on top of each other, all slightly differently timed and distorted, arriving by many paths.

This can be adapted for, somewhat. For that sort of application (triangulating from multiple passive fixed receivers scattered over the continent) confidence to less than within 50 miles would be hard to pull off. Though if you do get that kind of fix with some confidence, you can drive around -- when you're fairly close to a transmitter of that power (within line of sight), it's hard to miss it.

Practically, few of these types transmit continuously. (10 kW is quite the power bill.) If they're only on the air for a few hours, with changing locations, it's going to be difficult to find them.
I'm ok with this, but I wish they would do something about on street parking as well. People are still renting apartments and buying homes without parking, and they just use on street parking. Which is fine and all, but try being a pedestrian crossing the street when a car is parked way too close to the intersection (or be a driver where pedestrians seemingly pop into view from behind cars quickly). You really can't have your cake and eat it to, streets are not the solutions to our parking problems.

The unsatisfying answer to this is probably that it just doesn't matter. It's not as if evidence chain of custody is assured cryptographically; it's assured by rules and regulations and an adversarial system. If you tried to submit as evidence a forged document vouchsafed with a colliding MD5 hash, you'd be putting your own freedom at risk, because the forgery will be straightforwardly detectable (the real document won't have hash colliding artifacts in it).

None of this is to say that the legal profession shouldn't move to SHA2; it should.

In Haskell this should be "easy" to do using monads. You would have a process monad and an atomic monad (using Linux terminology). The operation to lock a sleeping mutex would live in the process monad. It would be possible to lift an atomic computation into process context (disabling interrupts) but not the other way around.

I don't think rust has such a concept of different computation contexts (does it?)

Of course Haskell may not be the most suitable kernel implementation language for other reasons...

It might be the case that the more complicated the artifact you're trying to forge is, the easier the MD5 forgery gets; the challenge with doing hash forgeries is that you lose control of some of the values and placement of bytes, which is more noticeable/disruptive in a short document than in a file that is a bunch of (seekable, error-recovering) formats at once.

(I've never tried to built one of these, so I could be just totally wrong here).

Interesting approach. Was it enough for your use case despite being quite cumbersome if you end up needing to save a bunch of different more complex instances? I mean, I imagine most dynamic objects that are the real state you'd care about will probably be allocated somewhere on the heap and be referenced from lists or pointer types. I guess this would work best for POD types like program settings and the like, so I'm curious about your setup there.

I immediately regretted my claim soon after posting it, and this was the first example I had in mind, along with this counterargument. If I was to make a further (somewhat weak) counter-argument, it was engineering know-how that established the Roman Empire as a dominant military in the first place, consuming the territories of other empires. It's a safer claim that technological asymmetry permitted the conquest of the less equipped 'societies', rather than 'empires'.

The CEO's "massive salary" isn't the issue. It's the "revenue declining" part. No one would care much about a salary like this for Baker or Eich is Mozilla was actually flourishing. But it certainly is not.

While Firefox market share and revenue is declining, Eich was able to a 200 person browser company from the ground up (based on Chromium). Huge difference between CEO caliber here.

I think we'd all be better off if those efforts would've been combined to making a strong 3rd browser contender, instead of Chrome, Safari, and the peanuts sprinkled across Firefox and Brave separately.

I don't know if you're intentionally using "colour" to reference https://journal.stuffwithstuff.com/2015/02/01/what-color-is-... ? Cooperative multitasking (which I'd never heard of before) seems from its Wikipedia page to be primarily concerned with Operating System-level operations, whereas that article deals with programming language-level design. Or perhaps they are not distinct from one another in your perspective?

I ask because I've found `async/await` to just be an irritating overhead; a hoop you need to jump through in order to achieve what you clearly wanted to do all along. You write (pseudocode) `var foo = myFunction()`, and (depending on your language of choice) you either get a compilation or a runtime error reminding you that what you really meant was `var foo = await myFunction()`. By contrast, a design where every function is synchronous (which, I'd guess, more closely matches most people intuition) can implement async behaviour when (rarely) desired by explicitly passing function invocations to an Executor (e.g. https://www.digitalocean.com/community/tutorials/how-to-use-...). I'd be curious to hear what advantages I'm missing out on! Is it that async behaviour is desired more-often in other problem areas I don't work in, or that there's some efficiency provided by async/await that Executors cannot provide, or something else?

This is more or less what I learned when I worked on forensics software, the kind that was supposed to maintain this kind of chain of custody/integrity. Like most things that touch the legal system, the presumption is that dishonesty or unsoundness in the chain of custody is fundamentally a legal problem with legal recourses, not something that can be solved with math.
