Game wise- a Scrabble that allows custom dictionaries made by the community to allow bilinguals to shine and use the findings for linguistics / sociology research (words removed vs words added, trends, measure new language acquisition from influencers, etc.).

Been a pet project idea of mine since the pandemic but never got around to it. I saw the new Rails framework is out and thought of starting this idea to learn Ruby.
Thx! Will add a search box this weekend
My few cents:

- Compute and storage separation simplifies managing a system making compute "ephemeral"

- Compute resources can be scaled separately without worrying about scaling storage

- Object storage provides much higher durability (99.999999999% on S3) compared to disks

- Open table formats on S3 become a universal interface in the data space allowing to bring many other data tools if necessary

- Costs at scale can actually be lower since there is no data transfer cost within the same region. For example, you can check out WarpStream (Kafka on object storage) case studies that claim saving 5-10x
Before I commented, and did a search to read about Alpha Genesis. Their website says one of their services is conducting experimental research on monkeys as designed by the customer.

I am not saying you are wrong. Your comment suggests you know the facility or at least live in the area and have some personal knowledge which certainly trumps anything I know (limited to searching the internet). After seeing your comment above, I did another search and the very top result was Google generated with a Q&A about this facility and the monkeys getting loose - and the first Q/A I saw had an answer that stated the monkeys at the facility are injected with disease (it is a confusing QA and I question the origin of what is posted).

We Know One Big Loser in This Election: The Mainstream Media
There is also the ABI compatibility guarantee:

https://doc.rust-lang.org/nightly/std/primitive.fn.html#abi-...

> The following types are guaranteed to be ABI-compatible:

> *const T, *mut T, &T, &mut T, Box<T> (specifically, only Box<T, Global>), and NonNull<T> are all ABI-compatible with each other for all T.

Honestly, this seems like something where the docs need to be clarified, but it's definitely intended that, if you transmute a reference into a pointer (explicitly, or implicitly through FFI as documented in that link), then you get a valid pointer to the type, not just an unknown blob that happens to have the same size and alignment. Likewise, any _valid_ pointer can be transmuted to a reference. It is already UB for a reference to be null or unaligned, but those are both cases of invalid pointers. (Note: rustc only uses null as a niche right now, not unaligned values, but unaligned values still cause UB because rustc tells LLVM's optimizer to assume alignment.)

If you want more evidence, here is a test for the improper_ctypes lint:

https://github.com/rust-lang/rust/blob/b91a3a05609a46f73d23e...

You can see that it's quite conservative about what can be passed through extern "C" functions without a warning, but &[u8; 4 as usize] is allowed, as is TransparentRef (a repr(transparent) struct containing a reference).

It is also guaranteed that you can transmute between pointers and optional references (i.e. Option<&T>), which are the same except that they do allow null:

https://github.com/rust-lang/rust/pull/60300

Thus, if you are writing FFI bindings for a C library, you are allowed to just declare pointer arguments as references, or as optional references, as long as the semantics line up. In practice this is not terribly common (outside of fn() types, which are treated like references), but it is allowed.

The RFC you cited as "certain kinds of references not even being stored as memory addresses at all" was rejected as a breaking change. If it had been adopted, it would have violated even the more-strict interpretation of the rule that pointers and references have the same layout, because it would have changed the size of references to zero-sized types (to zero).

Still really excited, but I'm pretty sad the in-wheel motors are gone. Unsprung weight like that is the devil for vehicular dynamics, finding a way to make the motor durable would have been so hard.

But I loved the idea of the cabin space being so free, not needing a motor compartment. Pity this won't be the vehicle.

Still, incredible focus on efficiency. I've been tempted to pre-order more than once (but probably going car-less instead).

Most roads aren’t even meant for cyclists but they feel so entitled as to take up entire lanes sometimes.
As a cyclist in vancouver I would say separated infrastructure is a mixed bag, I would have a car cutting me off (right hook as they say), many near misses when I had right of way several times a week on the dunsmuir bike path. I felt a lot safer biking in traffic in that area. OTOH I've enjoyed biking along the skytrain paths all the way out to surrey on occasion. The areas where the segregated path meet traffic have to be very carefully thought out.
Unless you have very little experience riding around cars, here's how I read that comment: 'I'm either too defensive/argumentative to tell the truth or I'm not honest with myself.'

Analogously: Since the the election, I've seen endless people blaming Biden, 'the media', etc etc. The only one I'll take seriously is the person who says: 'I failed; I should have done better.'
Someone discovered the halting problem again. Sigh.

First, the halting problem only applies to systems with infinite memory. If memory is finite and the system is deterministic, the program will either halt or repeat a state. The halting problem is thus decidable for non-infinite systems. So there.

The next question is whether there are programs with lower time bounds that can be made arbitrarily large. Actually, we don't know the answer to that. Cryptography assumes the answer is yes, but that's an assumption. We don't actually know that factoring is inherently hard, only that enough people have beaten on the problem that we know there's no easy to find shortcut.

Proof of correctness systems run into the complexity problem. You can write things that force a SAT solver to explore so many cases that it won't finish in any reasonable time. But that's not undecidability. My usual comment on this is that if your program is unreasonably hard to test for termination, it's broken. Microsoft takes that position with their Static Driver Verifier. There's a timeout; if it takes too long to prove your kernel driver safe, it doesn't get signed for use in the kernel.

> A lot of people use the proof that the halting problem is undesirable to make some deep philosophical point

Penrose comes to mind. There are people who are desperate to prove that humans transcend computers in some fundamental way. We heard a lot more from that crowd before LLMs started writing better than some of their critics.
ChatGPT does better -- it picks up context and produces more idiomatic output.

Kagi translate does pick up context (for instance, "Anne is older than her sister Carmen" is a good test for languages that have different words for older and younger sister -- Google Translate gets this wrong all the time).

But the Kagi output is stilted and grammatically incorrect for say, Cantonese.

Apple doesn’t have a stance of not unlocking phones for law enforcement. They give law enforcement whatever they’re asked for by subpoena.

Apple‘s stance is to build strong encryption so that they can’t access customers data. What they have refused to do is weaken that encryption so that they could start complying with future requests or sign tampered with firmware that would allow the decryption without user authorization.
Conservatives are always cosplaying Helen Keller when it suits them and not when it doesn't - just like everything else they could possibly do. It's an ideology of "how do I win this next sparring matc?" not one of consistency.
Beyond opaqueness, which could be overcome by simply prefixing the ID with something descriptive, I guess it helps avoid creating excessively long paths that might create problem onncertain filesystems, which is rarely a problem these days, but I have been bitten by it a half dozen times over the last few years. In a couple instances causing (recoverable) data loss.
I think you're right overall, but a lot of that is an unexamined reaction to a built environment designed for motor vehicles, rather than being designed for humans. In suburban America, it too often doesn't occur to people to walk even modest distances, and when they decide to try, the experience can be scary considering that they're likely to interact with inattentive truck/SUV drivers while crossing intersections. If I just crossed the major intersection on the way to work without being paranoid about vehicle traffic, I'd probably be wheelchair-bound by now.
I got hit by a car last weekend. It was the "left cross". Fortunately I wasn't seriously injured -- just a minor concussion -- and my bike wasn't badly damaged.

It's a weird situation. The guy who hit me stopped but seemed like a crackhead. There wasn't enough damage to require a police report or involve insurance. But maybe I should have just to create a record of this idiot causing accidents.
Thank you! A group chat is perfect for some links but also some downsides. Hard to find old links, you get pinged even if it’s not important, you get a link but don’t have time at that moment. This is a calm way to share links and has the serendipity of living on your Home Screen. I hope it feels more walkie talkie than text message.
1. Yes, everything is recorded on the block chain, but tumblers work. But yes, I agree it's hard to move large amounts of money on the blockchain since it's public.

2. "You're just explaining why crypto is becoming increasingly popular for businesses in general" Citation definitely needed. I used to see "pay with Bitcoin!" in a couple places online about 5-8 years ago. I never see it now, and hardly anyone I know, even big time "crypto people", actually use crypto to buy anything. Almost all the "uses" I hear are speculation or criminal uses. The only legitimate use I've actually seen is cross-border payments.
> America failing to police the world will lead to higher costs of living.

I don’t know what facts you’re basing this on but the US military action abroad is not correlated with higher standard of living in the US. In fact one could argue the opposite, but they’re not really interconnected.

> Drill baby drill

High oil prices are not because we’re not drilling enough. Oil production in the US is at an all time high and was higher under Biden than under Trump. (Not that I think it’s a good thing).

You need to reevaluate your news sources or do more research before you determine which set of policies are better for the common man as you put it.

Wind tunnels for scale size cars are much less useful than they were just 15 years ago. My university sold its wind tunnel for 1/10th scale cars, it was just not that useful compared to CFD. CFD can get you simulations that take into account rotating tires (a big deal on the open wheel cars we were working on). You also don't have to worry about inaccuracies from 3D printing (or however you make the model).
It’s communication in that information is being passed, but it’s a one-way Bluetooth broadcast. It’s not any kind of two-way communication.

At most an iPhone may be able to broadcast a Bluetooth message saying “anybody out there?“. I don’t even know if that’s possible. I’m sure Apple‘s white paper has the answer but I don’t remember it.
Apple calls this Activation Lock: https://support.apple.com/en-us/108794 https://support.apple.com/en-us/120610

Obviously, the logic board is locked to the owner's Apple account, but so is the display, battery, camera, and selfie camera. Basically the only thing you can reuse is the metal frame of the phone.

Phones are still stolen (since the cost of theft is $0) but stolen phones are worth closer to $5 than $1000.

whats wild is this was a solution to a problem that was directly caused by neoliberal capitalism.

in the 90s and 2000s when meth first began to spike, the rural economy was changing. Jobs weren't paying as well or were going away altogether. Meth found a niche as a kind of performance enhancement drug for people working long hours at physically demanding jobs. journalist Nick Reding found this in the pork industry in Iowa, and anthropologist Jason Pine found in general in Missouri.

neoliberalisms solution was a ham fisted market based restriction that turned a normal cold drug into a rarity. we didnt start working to treat methamphetamine addiction as a disease until it began to spread into more affluent white-collar neighborhoods.

this could have been avoided with competent market reforms and regulation, as well as stronger labor protections and minimum wage law.
> You actually don't have to power it down. If you hold the power and volume buttons for 2 seconds and reach the "slide to power off" screen, the phone is already hard locked. You then always have to enter the passcode to unlock it.

Iphones have 2 states when it comes to encryption:

Before First Unlock (BFU) - everything is encrypted. The most difficult state to hack.

After First Unlock (AFU) - data isn’t fully encrypted. Maybe it's for performance reasons. In this state exploits exist which police can use to get data.

Your suggestion of getting to the 'slide to power off' screen does NOT hardlock the phone (it does not put it in BFU).

It just means it requires a passcode. However, since it is in AFU mode, data can be exfiltrated with the right tools.

You should definitely power it down to be secure.

I've got mostly antiques at my house, 1750-1880. Not a ton of vintage 20th century stuff that would have radium. I was looking a bit ago at the old W. M. Gilbert Clock Company factory building in Connecticut that was for sale (not actually to buy, just thought it was interesting) and the biggest issue for whoever was going to be the buyer was that it was quite contaminated from the radium dial painting they did there in the 1930's.

Depends on the local laws, but mostly likely they are entitled to take the lane.
I am honestly not so sure. What's the evidence for this claim?
If there's not enough room for a car to pass safely (e.g., a wide shoulder, a bike lane, etc.), cyclists are encouraged to ride in the middle of the lane. If the cyclist rides on the side, cars try to squeeze past and eventually the worst will happen. Remember, 99% safety is almost certain death for a regular cyclist.

> The Hitchhiker's Guide to the Galaxy has a few things to say on the subject of towels. A towel, it says, is about the most massively useful thing an interstellar hitch hiker can have. Partly it has great practical value—you can wrap it around you for warmth as you bound across the cold moons of Jaglan Beta; you can lie on it on the brilliant marble‐sanded beaches of Santraginus V, inhaling the heady sea vapours; you can sleep under it beneath the stars which shine so redly on the desert world of Kakrafoon; use it to sail a mini raft down the slow heavy river Moth; wet it for use in hand‐to‐hand‐combat; wrap it round your head to ward off noxious fumes or to avoid the gaze of the Ravenous Bugblatter Beast of Traal (a mindbogglingly stupid animal, it assumes that if you can't see it, it can't see you—daft as a brush, but very ravenous); you can wave your towel in emergencies as a distress signal, and of course dry yourself off with it if it still seems to be clean enough.
The medical expense amount and every other direct cost is wild, but I guess I wonder how much would someone justifiably invoice to be hit by an ambulance. If it was a celebrity or ceo they'd probably bill quite a lot, but just a random guy?
You can use pledge[1] to restrict the tool to read/write only in specific directories, or only use certain system calls. This is easier to run than from a container or VM, but can be a bit fiddly to setup at first.

Assuming you trust it with the files in your codebase, and them being shared with third parties. Which is a hard pill to swallow for a proprietary program.

Great ideas! We'll keep this suggestion related to read/write separation in mind. We started with a simple unified solution, but we'll keep iterating, listening and addressing any feedback :)
> The importance of this design should not be understated. It's not really an obvious thing to realize. If it was, every other operating system and kernel out there would be doing it as well.

No, they would not. I can say this with confidence because at any point in the last several decades, any OS vendor could have started to do so, and they have not. They have uniformly decided that having a userspace library as their stable kernel interface is easier to maintain, so that's what they do. The idea that the rest of the world hasn't "realized" that, in addition to maintaining binary compatibility in their libc, they could also maintain binary compatible syscalls is nonsensical.

The Linux kernel, on the other hand, doesn't ship a userspace. If they wanted their stable interface to be a userspace library, they'd need to invent one! And that would be more work than providing stable syscalls.

> So Linux is actually pretty special. It's the only system where you actually can trash the entire userspace and rewrite the world in Rust.

That's not rewriting the world, that would be a new userspace for the Linux kernel. You're still calling down into C, there's just one fewer indirection along the way.

> So it doesn't follow that it needs a stable syscall interface. They could have solved it via user space impositions.

They could have, but as Greg Kroah-Hartman pointed out, that would have just shifted the complexity around. Stability at the syscall level is the simplest solution to the problem that the Linux project has, so that's what they do.

It would be pretty funny if the kernel's stability strategy was in service of allowing userspace to avoid linking a C library, considering it's been 30+ years and the Linux userspace is almost entirely C and C++ anyway.
Hard to find a family in rural America without a serial con somewhere at least in the extended family, usually due to drugs or alcohol unfortunately. It's relatable if anything.

They want cheaper gas prices first and foremost, and I guarantee that'll happen to some extent. Trump will expand drilling in the US, or reduce sales of our exports and divert them to the US, or something to that effect. The price of gas is a huge concern.

They don't want to hear any more about these culture movements they view as ridiculous, or for schools to teach their kids how to feel about $currentSocialMovement, especially when it goes directly against legitimately-held religious beliefs - "I can raise my kids how I want, thanks"-type attitude. This is the kindling for more parental rights political campaigns, which often includes the right to send your kid to whichever school you want.

They don't want to send money to Ukraine. Some know it's a lot of equipment, but it still costs money to send that, and there's an opportunity cost. It sucks what's happening over there, but they worry about being able to afford gas to get to work. They don't really care about what's going on half a world away.

etc. etc.

Plus, the media in general has been pretty aggressive towards Trump. Deserved or not, there's at least an air of truth to it. It's easy to dismiss a lot of concerns from the media. The Hunter Biden laptop thing (I haven't followed this at all) apparently is a big deal and seems to have massively fueled this idea.

I'm not going to reiterate their entire stance, because it probably varies from region to region anyways. Please don't shoot the messenger, I'm not going to argue their points, I'm simply summarizing what I've heard.
