No I really just mean the plain and simple scenario. Imagine you knew nothing about escape velocity or black holes, then you would not be confused at all by the idea that an object can move away from the Earth at any speed whatsoever, so long as its direction was away from the Earth. You don't need to move at Earth's escape velocity to move arbitrarily far away from the Earth. You could in principle travel all the way to the Andromeda galaxy without ever exceeding the Earth's escape velocity at any point.

Now for some reason when people talk about black holes existing because the escape velocity exceeds the speed of light, then it tricks people into thinking things they would never have otherwise thought, like in order to move away from an object you need to be moving at that object's escape velocity. Like somehow if you don't move away from an object at its escape velocity then you can't move away from that object at all.

Ignoring general relativity, if a black hole was nothing more than an object that had an escape velocity greater than the speed of light, then there's no reason why you couldn't enter the event horizon and then very slowly come back out, go back in, then sloooowly come back out, heck even come out and travel to an arbitrarily far galaxy and tell people about your adventure.

Escape velocity does not mean being unable to move away from an object, not for Earth and not for a black hole either. Escape velocity just means the velocity where no further propulsion or acceleration is needed to continue moving away from an object.

In general relativity, it's not simply that the escape velocity at the event horizon is equal to the speed of light, for if that were all there was to it, then simply bring some fuel with you to propel yourself away from the event horizon, feel free to do so at 1 cm an hour. In general relativity there are two perspectives, the perspective of the object entering the black hole where space-time curvature becomes so extreme that the spatial coordinate swaps places with the time coordinate in such a way that every future point is closer and closer to the singularity, and there is the perspective of an outside observer who sees an object getting closer to the event horizon undergo extreme time dilation and effectively freeze as their position perpetually smears itself across the entirety of the event horizon.
I did notice this when I had a city apartment with a window facing the street: regulators have not taken noise pollution into consideration. They made it very loud so as to be sure to alert all pedestrians, which is good, but it is also far more noticeable than a quiet ICE in several situations. If I’m in a building, I really do not want to hear a vehicle! Noise pollution is a real problem and the current regulations unfortunately do step backwards in my opinion.
I would say the most difficult part is to run it in production with minimal issues. Scaling them and making them robust to changes in data takes a long time.
How much innovation and small business is happening in industries where noncompetes are commonplace and how do salaries look?
That's done as part of xattr, or extended attributes. It's a very flexible system. For example you can add comments to a file so they are indexed by Spotlight.
I will not respond to everything because that would require a whole book but please let me highlight some historical facts that I feel you might have confused. You imply that famines were a regular occurrence under communism, this is wrong.

The was never a single famine in the Soviet Union after World War 2. In fact the CIA concluded that the Soviet citizens ate a similar amount of calories with slightly more nutritious food. [0]

Furthermore the idea of famines being typical for communism is contradicted by the basic historical fact that famines were a regular occurrence BEFORE the Soviets took power. The communist regime stopped famines from happening.

Comparing a famine that happened after the country was ravaged by the first world war AND a horrible civil war AND huge societal changes to planned industrial murder is insane.

> Nations plunged into poverty for generations.

Considering that Czarist Russia happened in one of the most backwards places on earth where people still used the wooden plow I would say the Soviet Union becoming a serious competitor to the US is very impressive. And current day Russia is doing rather well all things considered, surviving against at Western sanctions much longer than many predicted. I wouldn't want to live there but it is certainly doing better than many other countries in this world. China has seen a meteoric rise to power under a "communist" leadership. Cuba provide a vastly higher standard of living than comparable countries like Haiti.

It was mostly impoverished countries that have seen communist revolutions. You are confusing cause and effect.

Yes, Western Germany has done very well but is mostly due to the huge investment of the US in it as it was needed as a bulwark against communism.

We have an example on what the communists would do with Germany in Eastern Germany and well it is not very spectacular. No famines. No mass murder. The main issue where of course the wall between Eastern and Western Germany which separated families.

I will not deny the atrocities done during the Chinese Cultural Revolution, they are stomach turning. To say they are typical for communism is a bit dishonest considering the Soviets denounced Mao to the point that diplomatic ties broke. If we played the game like that, we would have to say that the Irish famine or rather genocide is to be considered typical for capitalism.

I don't really like comparing atrocities. Every single one is bad enough on their own.

The main point is that anyone with a shed of humanity has a duty to be anti-fascist first, after that we can battle out whatever system is better or worse.

Prosecutors seek to sweep this under the rug until the next time a plane crashes due to Boeing's corporate malfeasance.
Recently learned about https://coolify.io (as another option that seems worth considering).
I don't have anywhere near the background to fully understand the concept, and maybe this is a question that comes from reading too much sci-fi (or focuses too much on a practical question of a still very theoretical proposal), but isn't one of the main concerns with relativistic spaceflight the intense amount of energy which would be discharged by a collision with atomic or molecular elements of the interstellar medium?

Are there any other proposals out there today which address the risk of travelling through the interstellar medium at a high percentage of c?
Polymorphic Hard Drive Security Protocol (PHDSP) is a cutting-edge AI-based hard drive protection system. Inspired by advanced encryption mechanisms, it continuously monitors your hard drive for unauthorized access and modifications, dynamically rewrites its own code to thwart attacks, and ensures system integrity through self-healing mechanisms.
Are they talking about a reactionless drive? Or one of those drives where you move in the universe without actually changing velocity?

Jokes aside, I do the no note taking on the first read thing as well. Because I like reading, I do sometimes skip the problems in technical books the first time round, but I'm consciously aware it's a form of procrastination when I'm doing it.
NTFS ACLs (aka file permissions) are stored in alternate data streams.
Yes but Google hasn't needed gpus to power search. It's used cpu even for ML inference and training before deep learning.
Would a sub light warp drive be much different performance wise from, say, a fusion torch engine with insane iSP like the fictional Epstein drive from The Expanse?

Of course if we figured out how to build a sub light warp before figuring out how to build a fusion torch wouldn’t that be interesting?

So many more questions. Would you experience time dilation? When you kicked off the drive what would your momentum be relative to your destination? Would speeds like 99.99999% the speed of light be possible with enough energy? Of course you would probably be energy limited just like with crazy high iSP drives.

It’s possible that sub light warp drives are possible but FTL still just isn’t, or would require ludicrous “convert the mass of Jupiter into raw energy” levels of power.

Also if anything like this is possible it makes the Fermi paradox even more “real.” Right now the crazy difficulty of interstellar flight with reaction drives provides a solid chunk of a default explanation. If you could hit even say 20% light speed (effective velocity) you could hop between stars in practical lengths of time.

If someone builds any kind of working warp drive I’m going with either we are alone in at least our galaxy or UFOs are aliens, not much middle ground.
man pages vary in complexity/readability, and for occasional use, is probably way more painful
It would seem reactionless but physics wise you are actually warping space-time, so you are kinda just out of Newton’s domain entirely.
I was trying to come up with a 1700s-like explanation.
I think you are underestimating how long the scales are here. It could take 1000 years to be off by 15 minutes. By this time every electronic device that exists today will be either gone or in a museum.
Limiting free speech only makes sense if you're a bureaucrat. The government wants to control information, and how citizens use information. They derive power from this, and use it to manipulate the public.

I'm saddened by Tim Wu's arguments, I thought he was one of the good guys.
I would argue that the neutrino is relatively large compared to the quanta typical of these kinds of tests, but in the abstract they suggested a basketball!
Don't forget the GC rules for assigning times.

from https://en.wikipedia.org/wiki/General_classification:

Riders who finish in the same group are awarded the same time, with possible subtractions due to time bonuses. Two riders are said to have finished in the same group if the gap between them is less than three seconds. A crash or mechanical incident in the final 3 kilometres of a stage that finishes without a categorised climb usually means that riders thus affected are considered to have finished as part of the group they were with at the 3 km mark, so long as they finish the stage.

For this year's 5th stage of the Tour de France, the first 155 riders were assigned the same time.

All the best to them. Although I have to say (no reflection on these particular founders), that I am amazed that VC will through i million + seed at a startup with no actual product idea or business plan. This just seems like 'here's some money try to make something work' - incredible that this still happens in the US (I'm assuming). That approach is unlikely to work here in Asia / Australasia.
The river itself dried in around ~5000BC.
The text attributed itself as being authored in 3000BC.
The idea that text was written in 1500BC (3500 years ago) was proposed by Max Muller which was contested by his contemporary western and Indian scholars alike ( they proposed earlier dates)
In his late life, Max himself admitted that the dates he gave were hypothetical, they were to considered minimum and it could actually be more than that.
Think the FAANGs are doing part moat defending and part value add. Like AI powered spreadsheet might dethrone Excel so Excel has to be AI powered. MS will probably get some additional revenue from it but I don't think it will be a revolutionary amount.
I'd be more concerned about motor heat than battery heat. The battery should be very carefully climate-controlled, but the motors are more difficult.
Hah, I had the same thought. What kind of hacks can I do to convince the processor to keep as much of the emulator + opcodes in L1 as I can...
I spent so much time on "Road to Reality". I was mostly confused, but then every once in a while something would click and it was mind blowing. Now I'm going back through linear algebra. I'm also looking at the hardest book I've tried "Moonshine beyond the monster" I'm trying...
It is (ab)using QR code's own error correction to alter some pixels---I indeed confirmed that by modifying my own QR code generator written a decade ago. (Padded bytes after the terminator seem to be also exploited, but that should be okay.) A cube made of error-free QR codes would be cool.
i dont know how you can have such a strong opinion on cannibalism without trying it first. If attending a liberal arts college has taught me anything its that morality is relative and you shouldn't judge anything (except white people) without experiencing it.
This is indeed always a factor.
I thought it was suggesting exactly the opposite: that we handle this with tzdb updates, not leap seconds.
I wouldn’t do that to my users; the happy path here is nice, but the unhappy path seems very likely to end in garbled bash errors that are impossible to track down.

As a user, I’m fine with embedding a reasonably small VM to handle the configs; disk space is cheap. Better yet would be a compiled binary that handles it, but that feels like asking a lot of maintainers.

There’s a lot of surface area for someone to mis-quote stuff in their environment and generate unintelligible bash errors.

Or that may be just me; I hate bash in general, so maybe it’s just that bleeding over.
Unless the hosting company or a company like Cloudflare decides to cancel the wordpress site. I guess in theory as long as your Internet service provider is willing to give you a connection, you could host a local website. I guess.
I've found the compartments to be nicer than airline-style seating, even with strangers. A lot of the time though, you do get the compartment to yourself, or share it with just one other person. And of course, if you are travelling with friends or family, they can be in the compartment with you.

The empty "hallway" space outside the compartments is also nice. It means you can go out and walk around without bothering other people, not so easy on a airline-style car.

If you are agile, in a compartment you can climb up on the luggage racks above the seats and sleep there (I've done that). You need to give some (maybe non-verbal) assurance to the other people in the compartment that you aren't crazy. Again that's easiest when it's just a few people.

If the compartment has just 1 or 2 people, it's easy to lie down on the bench seats and sleep. With 3 or 4 people, you can flatten out the seats and everyone can sleep if they don't mind a little bit of squishing. As a college student I was fine with that. Maybe most of us here are too old for that by now.

A full compartment is imho certainly not noticeably worse than open plan seating. A non-full compartment is definitely better, if you have a bit of luck and get one. So think of buying an economy airline ticket that automatically comes with a chance of a free first-class upgrade, vs. one without such a chance.
Low-Speed Autonomous Mobile Robots (LS-AMRs) are an application of autonomous driving technology in specific low-speed scenarios, primarily used to perform simple, highly repetitive tasks. With the rapid advancement of sensor technology, computing power, and artificial intelligence algorithms, the autonomous navigation, obstacle avoidance, and path planning capabilities of low-speed mobile robots have significantly improved. These robots are now widely used in various industries, including warehouse management, hospital cleaning, airport luggage transportation, and retail store navigation.
Yeah. I think if I read Dream Machine first I would have enjoyed Wizards less. But some of the history was new to me which meant that I enjoyed Wizards for those aspects and then Dream Machine for the detailed look into why it happened.
More of a green-brown.
Sarcasm. Sorry for the confusion. For future, I'll add a "/s" suffix when I'm mocking reactionary talking points.
Very commonly used to hide malware and other things you don't want the average user or windows admin to find.
If you go back and look at the overhyped ads back then, you'd see them describing the future that we are currently living, except tainted by some institutions that were too-ingrained; things like "Using the World Wide Web, you will be able to view your checking account balance and make a payment to your utility provider with just a few clicks!" right after someone brings the milk in. i.e., They could predict online banking but not the rise of DoorDash.

Given the accelerated invention/deployment cycles we're in, it's not hard to extrapolate GPT4o to $0 token cost and 0ms latency. Even assuming stagnation in context lengths and cognition, the extreme scope of impact on every computerized industry becomes self-evident.
This is a very classic view, and while interesting, IMO the modern take doesn't start till lecture 22. I would expect a reformulation of the lecture series by now. As is, it reads as if an AI course does 21 lectures on Bayesian methods and then ends with a couple on neural networks: Bayesian tricks are neat, but not how I'd structure a general course. Cool but... I wonder what an update would look like.

(I overlapped in the same synthesis research lab as the author by a few years, and currently do LLMs for code synthesis in louie.ai... and much of the coursework was from around those Berkeley years and some MIT ones 10-20 years ago afaict. A lot of foundational work has happened since then.).
Linux is the only reliable way. I think boot camp drivers only support up to windows 8 and even 10 is out of support soon anyway.

Like the other poster I also didn't really have great experiences with opencore legacy patcher (in my case on a 2010 15" mbp). It's nice for a machine you're just messing around on but when you really care about security I don't think I'd rely on it.
I think they're implying AI has too much investment behind it to implode (i.e., it's "too big to fail").
Oh yeah, i did not mean to summarily dismiss “wrappers”, a word I have a strong distaste for. The thought there was that I have seen lopsided interest in AI from companies looking to deploy it versus normies looking to use it for any of their daily tasks.

> The combination of business / problem solving experience in the real world helps a lot to balance out what to do.

The pace at which this space is exhausting and exciting, but the thing that makes it exhilarating is that the newness makes it possible for anyone to have an original thought on how to generate better solutions. The problem solving experience stuff is definitely a big contributor to that. It’s fun figuring out something cool yourself, kind of a secret, and then seeing an inevitable paper or langchain tool 6 months later reflecting similar thinking.

I think we’ve progressed along this space in a similar way. The learning path probably is different now from than from two years ago on account of how much catch up there is to do. On top of that, thing can get stressful when you benchmark yourself against well-funded teams.

Your last several sentences resonate with me because that meaning keeps the stress at bay. I’ve always loved automation as a means of empowerment in everything I’ve done, but in the prior two decades, it all felt like a toy hobby. LLMs seem close to be able to unlock that potential for everybody, and i find that incredibly energizing.
Worldcom here. Ah, the Enrons of the internet.
Also I don’t think the original quote is purely about Linux bare metal because things like vPalos exist. It’s the whole shebang from VMware that people are going to want to get away from.
I find it fantastical that anyone in the geopolitical environment would put themselves at the (near instantaneous) mercy of someone that far away - physically and politically.

We’ve already seen the games played with hydrocarbon pipelines, and hydrocarbons are easy to store in large quantities, which greatly reduces the risk of someone playing ‘got you!’ on something that literally is a matter of life and death.

It still - clearly - happens, but when it does it isn’t as urgent as freezing to death tonight if you don’t do what they want. Unless they’re also bombing your storage tanks, which does happen, but is a significant escalation over ‘oops, we hit the power cable with an anchor again. Sorry!’.

For the Russia example, in the situations Russia wouldn’t want to cut it - the US and China would love to! Or have a proxy do it for them.

And if Russia has enough battery storage to last a week or two (minimum to outlast a storm; and also more than adequate to deal with daily insolation variation), they don’t have much of a need for these cables either, correct? At least most of the time.

In fact, in those cases the cables would actually present a bit of a problem, as they would potentially cause economic/trade/currency balances, similar to the Oil trade, and make it less economic to actually have the appropriate degree of local storage and production necessary.

The same issues pop up even regionally - Europe has a history of not always being super peaceful, so if, say, the UK wants to run a HVDC line to Spain, they have to think long and hard about the implications. As does Spain.

Because if Germany does that they did a few generations ago, that cable isn’t going to last long, and if the UK doesn’t have adequate safe alternatives, then they’re going to have a really hard time fighting back. And if Spain decides to raise rates to ruinous levels of the UK ‘brexits’, what leverage does the UK have?

Let alone not freezing to death. And Spain needs to consider they might be broke in such a situation, and having a hard time paying their own bills.

And if they do have adequate alternatives, then why is it a big deal to have the cable? What does it actually offer?

As to if it’s a single cable or a million of them or a lattice or whatever - the big question is ‘why?’ when the rest of these factors come into play. The materials cost to build and maintain it doesn’t help either.
I found Malcolm Wilcock, A companion to the Iliad, and Ralph Hexter, A guide to the Odyssey, helpful when I read Homer recently.
The most common DSP used for Sound OpenFirmware (SOF) is based around a Tensilica DSP. I've beenn curious if the Tensilica esp32 chips might be a natural port for this code...
https://thesofproject.github.io/latest/introduction/index.ht...

Annoyingly if you do have a real DSP you seemingly need Cadence's proprietary XCC compiler to use the Xtensa HiFi SIMD instructions. But given that these probably aren't available on these host cpus anyways the gcc build is probably just fine!

Would be cool to have some of the tip top DSP software actually usable. Alas SOF kind of gets to the last quarter mile then drops dead, isn't generally usable, it feels like. But something like this might perhaps make a somewhat interesting way of getting close-ish.
> Back in 1999 I was the technical lead for the Mac OS X Finder at Apple. At that time the Finder code base was some 8 years old and had reached the end of its useful life. Making any changes to it require huge engineering effort, and any changes usually broke two or three seemingly unrelated features. For Mac OS X we decided to rewrite the Finder from scratch.

Not that I don't appreciate your work from back then, but as a longtime daily Mac user I cannot wait for the day that this is done once again. The Finder has so many bizarre quirks and it's so slow to proliferate updates that it's just embarrassing. Not to mention it's actually capable of locking up waiting for network access in some circumstances.

I don't know what the Finder source code looks like today but I bet it's a similar kind of hell project as the Classic Finder was back then when they first rewrote it, considering how reluctant they are to do anything to it.
