Just at the small cost of your soul. For some this is a small price to pay, and for others, the cost is enormous. Will AI make fundimental differences in the way life works? Look at every single stoplight that is green while no cars are waiting.

Is Floki the paradigm for crypto governance problems?
Yeah some names make a concept more confusing. Dependency injection is definitely one of those. I understand where the name comes from but it's just a really bad name. Sounds way more complex than it is.

Still, not as bad as "dynamic programming". Sounds complicated right? It's just recursion with caching. There the name was almost deliberately bad. "dynamic" is just a generic fancy sounding adjective (yeah really), and "programming" is not a reference to coding; it's a reference to scheduling. Because that's not at all confusing... "Cached recursion" doesn't sound like you've really invented anything though I guess.

Please can we all call it "cached recursion" from now on?
That explains Fallingwater.
Storage can be further reduced if we think that, with a 64-bit processor, probably a 32-bit address space is enough for most applications (that require less than 4 GB of RAM).

Maybe we can go even deeper with 16-bit near/relative pointers. Perhaps data-oriented design fits well in this situation? With blocks of 64k elements and uint16 indices to address elements inside of them.
There's also the [kademlia distributed hash table](https://pdos.csail.mit.edu/~petar/papers/maymounkov-kademlia...). The high level idea is that each node gets a random bit in the range [0, 2^m), and we define the distance to be XOR. We want to find a distributed algorithm to quickly get some information from X to Y, without knowing the whole network.

You can just look at the math and prove that it works, but my pet favorite visual interpretation of the algorithm is this:

Suppose you have a start node X, and it wants to find node k. Define the "X-distance tree" to be a binary tree, with leaf indices 0, 1, 2... But you put labels of X^leaf_index in each node, to represent the distance from a certain label to X. E.g. dist(x, x) = x^x = 0, so the label "X" (the original node) is put at the leftmost leaf (0).

The interval [2^i, 2^(i+1)) is some subtree of the X-distance tree. Let's say you know k's distance belongs in that interval, so you query some node Y in there as an approximate neighbor.

No matter what node Y you pick, the resulting prefix in the Y-distance tree will always be some permutation of the [2^i ,2^(i+1)) subtree we picked from the X-distance tree!

More specifically, my claim is that at the sets labels_of_leaves_of_X( [2^i, 2^(i+1)) ) == labels_of_leaves_of_Y( [0, 2^i) ). (recall that we index by distance, but the labels might be different).

There are far more rigorous comparisons to other DHT's like Chord, both mathematically and empircally. But to me, this visual intuition tells me what the "symmetry" of Kademlia means - sort of everybody's in their own local neighborhood, their own subtrees.

Whereas Chord, even if you implement it bi-directionally (which costs 2x memory! and seems even more treacherous to implement...), can't get this level of 'isolation' in some sense. The neighborhood sliding window of size S is always shifting: per bit, there's always 2^m distinct neighborhoods. Yea, even though most neighborhoods "look the same", it's just not pretty.

Kademlia has 1 + 2 + 4 ... + 2^m-1 neighborhoods, and it's all neat and tidy.

I bet Google is utilizing the value of the LLM input prompts with close to the same efficiency they are monetizing search. I that case, there are two questions -- 1) will LLM overtake search? and 2) can anyone beat Google at monetizing these inputs? I think the answer to both is no. Google already has a wide experience lead monetizing queries. And personally, I'd rather have a search engine that does a better job of excluding spam without having to worry whether or not it's making stuff up. Kagi has a better search than any of the LLMs (except for local results like restaurants/maps).

Yes if you search, lots of people have shared evidence of this. But it depends on which model you’re using, as some seemingly don’t have the bias built into their training.
I don't know that for sure but 630nm is much more common. Look at the wavelength column here, it's all ~630nm:

The unexpected consequences of design patterns in software development
It looks like they sourced tasks via a public Github repository, which is possibly part of the training dataset for the LLM. (It is not clear based on my scan whether the actual answers are also possibly in the public corpus).

Does this work as an experiment if the questions under test were also used to train the LLMs?
I had an Apple TV connected to a TCL Roku TV and the TV was analyzing video frames from the AppleTV to popup ads suggesting to watch the same content on other streaming services.
I got my first migraine in my early teens. I was over at a friend's house and we were playing in the basement on a summer day, then went outside where the sun reflected off a window into my eyes.

It would start with a shimmering pattern obstructing my vision where the bright light was, which would grow into a c shape and get bigger until it surrounded my vision and then faded away. About 15 min after the shimmering pattern faded the blistering pain would start and last for about 5 hours, with lingering light sensitivity until the next day.

I later realized that something about a rapid change in brightness (from dark to bright) would trigger them for me.

Another time was triggered by a high school shop teacher lighting a welding torch.

The best way to relieve the pain I found was to turn out all the lights and dunk my head in cold water, which I discovered eventually in desperation for relief.

I would only get them every few months, but when I did I would be pretty useless for most of the day. I stopped getting them in my early 20s. No idea why, but I am grateful. They sucked!
That probably won't come close to justifying the current valuation of either OpenAI or Grok (idk how much investment it took in or how much it has spent so far).
IIRC (from memory) it was called Source because it was a derivative of the Quake 2 engine that id gave them a copy of after a meeting (on a cd simply labeled “source”) even before they had a contract in place.

If this apocryphal story is true, they might only have a license to it (making it a derivative work) and depending on the terms of their licensing agreement from id they might not be able to do that without having their legal people talk to ZeniMax’s (they bought out id software and are their parent company now) lawyers, which runs to thousands of dollars in pure costs even if everyone is totally cooperative and on board and wants to make it happen immediately.

> and (to an increasingly smaller extent) automotive maintenance

I disagree, with the cost of maintenance these days. The cheapest shops in my area (large city, Canada) charge $110/h, reputable (and/or German) charge $125-$150/h, and dealerships start there and go up. I know people paying $100 for a seasonal tire change (swapping rims, not dismount/remount), plus storage for your off-season tires. A good jack and stand set is $180 ish, and you can either buy a breaker bar for $30 or an impact for $100, along with a torque wrench for $40, and be set for life for tire changes. The tools will pay for themselves in a year and then save you every year thereafter. And you now have the basics to do the easy-to-get-to stuff like brakes and suspension components, saving you even more.

Of all the trades, automotive is one of the easiest (and cheapest) to start doing yourself, aside from maybe plumbing. Especially if you have a second car to rely on in case you’re not confident in your ability to get a job done on time.

Some auras have a musculo-skeletal origin. For example, some neck issue irritates a nerve or alters the pressure in a blood vessel, which in turn affects the optic nerve.

I have suffered them myself, and they always came in a sequence: arm pain, neck pain, headache and aura. Finally, I'd release tension in my neck and it'd be gone.

My doctor confirmed injuries in cervical discs also seem to be causally linked to auras, but there might be other causes as well.

Because just like virtually everything in the embedded SoC ecosystem outside of the RPi competitor SBC crowd, the TV embedded board likely has a chip with little or no doc (with or without NDA), and unlike a Pi-ish SCB there's probably not even an unsupported, outdated kernel linked with a ton of opaque proprietary blobs hidden on an obscure Chinese language web site to try out.

Maybe there are smart TVs out there with a SoC that's been reverse engineered enough to do something with. If there is, that should be shouted from the rafters. But I kinda doubt it.
I used to love pihole, but it seems like it's more trouble than it's worth now. Advertisers have wised up and will use the same subdomain for both content and ads. I've also had issues with normal website functionality being broken due to pihole which isn't fun for my wife. It seems mostly useful for blocking background traffic on smart devices, not so much for ads.

uv is so much better than everything else, I'm just can't afraid they can't keep the team going. Time will tell but I just use uv and ruff in every project now tbh.
> I had a friend who decided to not use uv, because the first time he used it, it was on a 15 years old codebase that had just been migrated to Python 3. It was standing on a pile of never cleaned up pip freeze exports, and uv could not make it work.

This is my only gripe with uv, despite how the author decided to depict it, this really turns into a headache fast as soon as you have ~4-5 in-house packages.

I don't think it's that bad that uv is so unforgiving in those case because it leads to better overall project quality/cohesion, but I wish there was a way to more progressively onboard and downgrade minor version mismatch to warnings.
I think this is hopelessly optimistic. From what I can tell, they have not even started building the ARC reactor. There is about zero reason to believe that all the completely unproven concepts, like the molten-salt liquid blanket (or tritium breeding in general) are gonna work without a hitch and zero delays-- thats just straight up self-delusional.

In comparison with ITER, the have the advantage of newer magnet technology (which certainly helps!), but thats the only actually proven thing, and every other aspect of ARC is basically complete vaporware.

It would be a very pleasant surprise to have them extract electrical energy from the thing in early 2030, but I'm not even holding my breath for first plasma by then. But we'll see.

The startup time comparisons may not seem like a big deal but having an app take several seconds just to start up can burn you really bad in incidents where you want to roll new application versions. And yes, it is possible to engineer around it but I think a better question to ask is why these apps take so goddamn long to start in the first place. There should be some kind of compile or runtime flag to speed this up.
The only mature, production-used exception of which I can think is Naughty Dog's Game Oriented Object Lisp/Game Oriented Assembly Lisp. EDIT: I was wrong, wikipedia claims there are basic GC functions. I can't speak to the details, but I imagine that whatever they have would attempt to lift allocations out of the hot path/use arena allocation or some similar mechanism.

That said, people have strong opinions on whether reference counting counts as GC. I say it does, but others are vehement that it does not. If it does not count as GC, I think Interlisp-D would qualify.
The main problem is that the system forces people to present completely unreasonable levels of productivity just to get jobs—not make tenure at Harvard at 32, just to get regular jobs. But this also creates a diffusion of responsibility—if everyone is forced to do it, then no one can call anyone else out. The only ones who conceivably could would be the ones who don’t make it, but who would listen to them?

I started having migraines at 8 years of age, several a week. This persisted all through my life till 42 years later, I had a blood pressure emergency where I ended up in ER with 190/100 blood pressure. Thankfully, it never repeated and was never diagnosed but as a consequence I was put on Olmesartan, a blood pressure medication that relaxes the blood vessels. Eventually, the dose was reduced to the lowest, 5mg, once a day, to which I added 240mg magnesium glycinate, which they sell in Costco. I have been mostly migraine free since for several years and ones I do get are mild compared to before.

My cardiologist, who prescribed the blood pressure medication, is mystified saying that while beta blockers are a migraine prevention medication, olmesartan isn't a beta blocker and maybe it was just my (mild) hypertension which needed to be treated. I doubt that I had hypertension when I was 8 but I'm just thankful that decades of pain have come to an end.
O3DE came from Amazon Lumberyard which came from CryEngine, so it's quite possibly one of the better looking open source 3D game engines that you can currently get, no strings attached: https://github.com/o3de/o3de

Sadly, you need to put in a lot of work to get good results out of it (neither of its predecessors had a reputation for being easy to work with) and for whatever reason many studios aren't exactly rushing to invest a bunch of time into it (many just go for Unreal Engine 5, or stick with Unity etc., indies often opt for Godot), so you don't get much past simple example projects. Part of this is probably that it never generated a lot of hype or much of a community around it.

Godot has a big community around it and is maturing pretty quickly, the early versions were pretty rough when it came to 3D (2.X and 3.X), but it's better now. Not as stable as Unity or Unreal but those have had the advantage of lots of years of work put into them, by more people than Godot has up until now.

There's also more niche options like Stride (https://www.stride3d.net/) and Flax (https://flaxengine.com/) but they suffer from the same issues as O3DE, even if otherwise are promising.

Something not discussed in the article - and to me what’s wildest about this example - is the variance from first-timer to professional; or even Amateur Who Has Done This Kind of Thing Before.

A professional would’ve had all the tools and experience using them, so no trips to the store and no $10 rental. They would’ve known about the need to drill the drain hole. All making the job far quicker, possibly near the original estimate!

Agree. Go is a joy to use. Java is okay but struggles with scaling unless you have the money to burn for this.

To scale up servers in Java requires spinning up highly priced servers with lots of RAM, which that is a lot of money. Using a low spec server is cheaper but you will get more JVM crashes and have to waste time doing more JVM tuning to prevent them. This is not even talking about having lots of 'microservices' to scale which that also means more money spent per month.

Using Go just reduces all of that and saves lots of money and is extremely efficient enough to rely on and it directly compiles to a single binary for deployment.

From a cost and efficiency perspective, Java is just not the answer even though it is a sound language, unlike JavaScript or TypeScript. Given a choice I'd rather use Java or even Kotlin or JS/TS. But the cost reduction, performance gains and onboarding experience with Golang is hard to beat for backend.

Would stay really far away from JavaScript or TypeScript for anything backend.
I've had a raspberry pi and pihole going on the same SD card for approximately seven years now.

I also regularly reboot the pi by simply cycling power.

The solution was fairly simple. Send the linux log files to /dev/null (or whatever it is actually called, i.e. RAM) and disable query logging in pihole.

That's it. Helps greatly!

Subjective evaluation of "humanity" and "empathy" in responses is much less important than clinical outcome.

Erosion of trust online seems like a major negative consequence of all the generative AI slop (LLM or otherwise).

The particles affected by the ionizer are already floating in the air that is being inhaled into the lungs.

Wikipedia has a note on XOR linked lists.[1] That's a more general form of this concept.
This technique is decades older than the references there indicate.

"revive an old computer with gnu/linux" has been a meme for like 25 years now. to some degree it's less true nowadays because most stuff run in the web browser, and web browsers are total memory hogs. but ad the same time, with any decent gnu/linux you won't be running spyware/adware and useless ai stuff nobody asked for so yeah i'm going to keep assuming linux is noticeably faster even if i haven't used a windows laptop for personal use in ~15 years.
