Eh, that feels like where things were heading even without generative AI. Just try to imagine your headspace between the January 2019 and ~late 2022... Personally, I was already worrying about this.

Generative AI accelerated things greatly, but I dont think it even changed the trajectory.
It's incredibly useful in read-only, memory constrained scenarios. I.E. we used to mmap all of our animation data on many rendering engines I worked on where having ~20-50mb of animation data and only "paying" a couple 10s of kb based on usage patterns was very handy. It becomes even more powerful when you have multiple processes sharing that data and the kernel is able to re-use clean pages across processes.

From reading the paper most of the concerns are around the write side. LMDB is the primary implementation that I know which leans heavily into mmap but it also comes with a number of constraints there(single writer, read locks can lead to unbounded appending to the WAL, etc). As with any tech choice it's about knowing constraints/trade-offs and making appropriate choices for your domain.
It's unfortunate that Sony didn't try again after the PSVita.. the PSP was clearly ahead of its time, hopefully the Nintendo Switch success will encourage Sony to try again, and Xbox to finally dive into the handheld market

Can you give some examples where mmap is useful?

So glad to hear it. After the talk I nearly had an out of body experience in the lobby afterward hearing people talk positively about what to me was a hot mess.
I'm not sure why this was posted. Perhaps it was due to recent blogging by Nick Pelling on the subject at https://www.ciphermysteries.com/ ? There are quite a few entries now over a period of months that started from a reported cipher at Roswell.

Imagine you are a small island nation reliant on imports from american companies and american foreign aid and attempt to violate US imposed sanctions on another state. You’d probably lose your seat of power before long from the resulting social unrest from being economically isolated from the US and all her allies. US might even back an upstart power against you with money or arms or paramilitary training.
So is social media, and social media is likely worse, but hopefully you apply the same logic to that?

Maybe, maybe not. Most of the out people I know from I-banking, never once achieve the stature that they previously held at their last up or out position.
It's not really problem with being "perfectly specced" or not, it's just matter of inertia.

If markdown just used bold _italics_ at the start, or needed a tag for HTML instead of passing it as is... it would be entirely fine and just as popular now. Or any other generally agreed upon as "good" fix.

But inertia makes things like that near-impossible to change now. Only additions can sorta work and even those are hard as critical mass of dialects needs to apply them for it to work.
“What was most interesting to me was a repetitive sentence that he said to me over and over again. And that was the strategy that was being used to educate the public and decision makers, and the scare tactics, the spin that was being put on the weapons system. And that was how we identify an enemy. The enemy at first, he said, the enemy against whom we’re going to build a space-based weapons system. First, the Russians are going to be considered the enemy, then terrorists would be identified and that was soon to follow. Then we were going to identify third world crazies, we now call them nations of concern. The next enemy was asteroids [and] against asteroids we’re going to build space-based weapons.

“And the funniest one of all, was against what he called aliens, extraterrestrials – that would be the final card. And over, and over, and over during the four years that I knew him and was giving his speeches for him, he would bring up that last card. ‘And remember Carol, the last card is the alien card. We’re going to have to build space-based weapons against aliens’, and all of it, he said, is a lie.” -Werner von Braun to Carol Rosin [0]

Regarding disabling loading the .envrc from direnv, it works from an allowlist instead. The first time you cd into a directory with a .envrc you are prompted to `direnv allow` before it will take any action.
By far the easiest way to work with .blend files is to shell out to Blender, let it open the file for you, and use Blender's Python API to get whatever you need.

blender -b your_file.blend -P python_script.py

Besides not having to parse the file yourself, there's lots of stuff (like "where is this object on frame X") that can't be read from .blend alone but need the actual algorithms Blender uses, so it's easiest to just reuse Blender itself.

The downside is the Python API breaks all the time.
Yes; one way to see this is with a little calculus. It all boils down to the fact that the indefinite integral of x^(n-1) is x^n / n. (That's where 1/n comes in.)

Suppose we have an n-dimensional pyramid. It has an (n-1)-dim'l base with volume B, and that base tapers to a point; for simplicity, it has height 1.

Take cross-sections as we travel from the base to the height. How big is a cross section at height y?

Each cross section is a (n-1)-dim'l shape, and its volume is B * y^(n-1) because this is how volumes scale in dimension n-1. [Examples: In 2D if you x2 the sides of a shape, it's "volume" (area) is x4. In 3D if you x2 the sides of a shape, it's volume is x8; in 4D it would be x16, etc.]

Now take the integral to add all of these cross-sections:

integral(from 0 to 1 of B * y^(n-1))
= B * y^n / n evaluated from 0 to 1
= B / n.

If the shape is scaled along the height dimension by h, then we get the more general formula:

volume = h * B / n.

Don't get your hopes up, and keep brushing your teeth: "The tooth regrowth medicine is intended for people who lack a full set of adult teeth due to congenital factors (anodontia)".

Another interesting limitation of mmap() is that real-world storage volumes can exceed the virtual address space a CPU can address. A 64-bit CPU may have 64-bit pointers but typically cannot address anywhere close to 64 bits of memory, virtually or physically. A normal buffer pool does not have this limitation. You can get EC2 instances on AWS with more direct-attached storage than addressable virtual address space on the local microarchitecture.

It seems likely to me that people get used to certain flavour profiles and the heavy use of sweeteners is going to prime people into desiring sweet foods and drinks. I don't know if the body then responds with hunger if it's promised sweet, highly calorific food/drink and then receives fake calories.
> American culture

People online seem to have such a fascination with finding every possible thing wrong with American culture. Then they generalize across 330 million people, and completely ignore that the rest of the world has equally incomprehensible or destructive habits.

I guess we should be honored? Nobody bothers criticizing Europeans because Europe is largely irrelevant.
Yeah, but it's exactly what I've come to expect from Tesla.
I've moved from "traditional" software engineering to a role of working with ML (building + deploying models used in product features) and of the team I work with - and my extended communication with developers at other companies making the same transition - every single person has said the Francis Chollet book (Deep Learning with Python) is all they really needed.

It walks a very thin line between too little info and *just* enough to get you to the point where you know what you don't know (the productive point) and it explains the Math in code samples. It really is a very good way of teaching. When I was reading, I thought the theory covered was too far from the Mathematical base, but I found my self being surprised at how I could hold my own in discussions that moved in to theory.

That said, this likely won't be enough for you to be a researcher - but I imagine for a lot of people tempted by courses like the OP - that isn't the actual end goal anyway.
I don't know how friendly or unfriendly previous empires were, so I'd like to read up more on it, but I honestly don't know what keywords I'd look for.

This is what I use, it does have its frustrations.
I sometimes run into it by accident then look at the ui and the prices in disbelief. Its always a joke by comparison.

Bling has this rather weird feature that allows you to search for similar (product) imaged, I don't know how often it works but iirc it displays prices under the similar (read the same) products.

I think eventually that might become a desirable standard. A platform, interested in the long game, wouldn't want to sell the same goods for 4 to 50 times the regular price. Just like brick stores use to guarantee the lowest price.
Its by design. Military is a separate entity from domestic elected government the world over. If you know anyone who is in the leadership side of the military or in the state dept, its very interesting having conversations learning about how these agencies view the world and how actual power is manifested.
I like the direction you are thinking Kevin, clearly you have a background in law and it's noticeable in what you're launching with script.

Show HN: FileMonger – Vim Undotree for Any File
I've built FileMonger mostly because I needed a way to track the change history and show diffs for screenplay formats (FadeIn and Final Draft).

Once such a file is added to FileMonger, every save is stored in the history tree.

Handling Screenplay files is similar to Word documents, so I've expanded the functionality so it'll be useful to more people by having previews and diffs for other formats as well (you could track any file under ~50MiB, but not all file types can be previewed).

> they markedly changes the taste, indelibly affecting the thing it's sweetening. Heck, even stevia adds its own distinct nastiness to whatever it flavours.

This really depends on personal tastes and on which food is used.

I use aspartame-based sweeteners on milk products, and I can't distinguish it from sugar.

On the other hand, Stevia tastes terrible to me in any food/drink and quantity.
Briefly mentioned in this and rendered: space exploration is an incredible factorio mod and the deepest game I've ever played.

In Factorio you launch a rocket and win. Space exploration takes that and continues. You end up developing a base across multiple worlds in the solar system. After developing the solar system from the different unique resources on each planet you expand to interstellar space and then other solar systems. The game has a 'quarter of the way through' victory screen but there's another victory screen as you explore a mystery that spans the known universe and takes a reasonable amount of math knowledge figure out.

It's 100s of hours of gameplay and really well done. They modified the game so that you can fly spaceships between planets with a star and solar system maps and it all works really well.

Just make sure to turn the biters way down. The mod requires a level of patience and the intensity of combat runs counter to that (in fact the mod itself has a popup telling you to turn biters down on start).

> If the rules are too complicated, then they are a challenge for all parties, both users and implementers.

You are still confouding rules for writing with rules for parsing. It's absolutely possible and easy to make rules making writing easier but parsing harder.

For example, if you make rule that makes formatting markers like **\_ be order insensitive (so **_word**_ formats same as **_word_**), much easier for user, as they don't need to remember order of which the operators were used, harder to code (I assume)

Tesla is number 50 of the Fortune 500, and you're telling me they can't figure out how to make this work profitably? Surely other car manufacturers have figured this out.
There's two major safety issues:

You can't see around cars to be able to pass. Okay, so you often don't pass.

But much more importantly, car headlights aren't symmetrical. The one pointing towards the oncoming lane has a "cut" beam to avoid blinding other drivers while the other has a taller beam to improve visibility of anything entering the road. When you drive LHD in a RHD country, or vice versa, you are blinding other drivers while having low visibility of pedestrians and animals.

Technology Connections did a great video about this. His solution was to stop driving his RHD car in low light. https://www.youtube.com/watch?v=c2J91UG6Fn8
Nim needs a succession plan in order to be more successful. And by "successful" I mean more widely adopted and used.

Lots of people are very reluctant to invest time, money and effort in anything with an unplanned, unsettled or uncertain future --- and rightfully so.

Stuff happens --- sometimes quite unexpectedly. One thing is for sure --- if you don't plan for the future you will be caught off guard at some point.

On the other hand, if no one in a position of authority really cares about this sort of thing, that is useful information too.

I mainly see it (in the USA) with contract rural mail carriers. They often use RHD Jeeps or Subarus so they can reach roadside mailboxes. And of course the official USPS residential delivery vehicles are mostly RHD.

Occasionally you see some cars fitted with contraptions that use cables and pulleys to allow control of a LHD car from the right front seat. I'm surprised these are legal.

Ironically, using an old tech incandescent lamp in place of the LED would make the detection impossible, the reason being that incandescent lamps are way slower to turn on and off than LEDs, therefore it would work as a low pass filter just like putting a capacitor in parallel to the LED, which makes a RC filter paired with the series resistor preceding it.

Of course one could still use LEDs of which they have gained control for exfiltrating information, whether LEDs have a capacitor in parallel or not. If there is a capacitor and the LED can't be turned on and off effectively at say more than 5Hz, one could just use 1Hz pulses and, given enough time, transmit the information anyway.

If your data is likely to already be in the system cache, memory mapping can achieve zero copying of the data, whereas reading will perform at least one memcpy. So there can be a performance advantage depending on the usage pattern.

Also, I've never tested this, but I believe mapped files will get flushed as long as the system stays running. So if you only need resilience against abnormal termination rather than system crashes, it seems like a good option?
In case anyone missed it the gif in the first answer is actually in stereo, if you relax your eyes it’s 3D.

No, the problem also applies to Tor. If a malicious actor controls large parts of the network, there is a high probability that the attacker controls your entire circuit or at least your entry and exit node.

In the latter case, you can do timing attacks to determine which traffic on the exit node belongs to whom on the entry node.

Every single positive aspect of the production of oil you listed has been paid for by some consumer at the pump or in the store at some point. And by governments/taxes through subsidies for oil companies. Consumers and citizens not only paid for the cost of everything you listed, they also paid for the (substantial) profits of the oil company's shareholders. Yes, some of that value creation also benefited overall economic growth but that is the same for literally every kind of business transaction and economic innovation.

Overall, the quality of life for most people at the moment is certainly higher than it would have been if oil has never been developed as a natural resource. But the risk of unmitigated climate change (which largely is due to humanity's consumption of fossil fuels) is that this equation will shift in the coming years and the use of oil, coal, etc. will turn out to have had a net negative impact on human quality of life.
It's pretty common for some low production cars. For instance many Lotus cars in continental Europe are RHD, because RHD Lotus are much more common and less expensive.
