I went on a Jhourney retreat with about a year of daily practice under my belt. I didn't reach jhana, and was a bit discouraged after finding out that almost everyone else around me had! I think around 75% of those who attended based on my calculations. Including those with almost no background in meditation at all. But also some people who came to the retreat had already had access to these states. I do credit the retreat for reinvigorating my practice though, and reinforcing that jhana or no you should be aiming to be relaxed and joyful after most meditation sessions or you're probably doing it wrong.
Yeah exactly. With realtime, a dropped packet is often too old by the time it's re-transmitted. It's actually harmful to wait for it when you'd rather just skip it and move on and stay as close to realtime as possible. It's a very different usecase from most uses.

I do wish QUIC allowed carrying streams that were useful for realtime in conjunction with allowing reliable streams. Using MPEG-TS over SRT to have it just spam metadata to handle the unreliableness is janky. It would be far nicer to have a reliable stream for metadata, then an unreliable one for realtime streaming.
The fact that you feel like you can't have human interaction or community unless you're walking somewhere sounds like a skill issue on your part.

The short answer is that the technology as of today works and is useful. Text summarization. Text rephrasing. Image, text and video generation. Intent extraction. Voice generation. AI brings structure to previously unstructured data. AI allows us to solve problems we couldn't solve before where we aren't smart enough to write down the rules but we are smart enough to collect and label examples. It's imperfect but it works well enough to be useful - the dumb hype is driven by usecases that haven't found the right use of the technology given current accuracy realities. If you have enough data and can frame a problem as a sequence problem, these models can help you solve it. The hardware and software is rapidly improving and costs will go down. As the productization of this tech gets better we are better able to leverage today's technology in useful ways - consider chatgpt vs copilot vs cursor as ways of leveraging AI to help with coding.
What do you think about twim jhanas, which are similarly "light"?

Multi-GPU Parallel Computing Based Regional Scale Traffic Simulation Framework
I've been learning Alloy[0], which I think is probably more practical for most software engineers. I'm using it with the goal of documenting and decomposing a legacy system that I've been working with for a number of years.

It's more geared towards the static elements of the system, and writing a spec feels quite like writing a relational database schema -- mostly because they're both expressions of relationships.

It seems like a pretty natural path to write a spec in alloy before building out some crud interface.

I think there's a huge tooling gap though. Alloy, TLA+ and friends all seem to be very jvm/UI centric, really targeting a user who is working in the editors the language ships with.

I'd really love to see more tooling to run model checkers in a CI pipeline, or generate stubs and test cases for various languages. If that were in place, I think there would be more stickiness to formal methods.

I've started writing a Go parser for alloy, in part to learn it better, in part because I know go and want to write some tooling that I think go would be a good implementation language for. I don't know if anything will come of it, but at least having a parser would allow for things like a formatter or code generator. If I were feeling ambitious, I might try to implement a model checker.

The legislation requiring this is silly, are there any studies at all which shows it reduces harm... I couldn't find any. It would seem safer for children, and the population as a whole, if they banned vehicles which don't provide adequate front visibility. Maybe even require sensors that will prevent the vehicle from moving from a stop if something is detected in front.

Lying is intentional, algorithms and computers do not have intentions. People can lie, computers can only execute their programmed instructions. Much of AI discourse is extremely confusing and confused because people keep attributing needs and intentions to computers and algorithms.

The social media gurus don't help with these issues by claiming that non-intentional objects are going to cause humanity's demise when there are much more pertinent issues to be concerned about like global warming, corporate malfeasance, and the general plundering of the biosphere. Algorithms that lie are not even in the top 100 list of things that people should be concerned about.

I'm not that familiar with them but the people I know that do the traditional jhanas I think some think they are mistaking a profound state called "bhavanga" for jhana. (It's mentioned page 140 of Mindfulness Bliss and Beyond by Ajahn Brahm and in the first few pages of Pa Auks book as something often mistaken for jhana and nibanna - a sort of cessation).
This is not some secret:

I don't want to go screen videos right now, but his is vague and misleading about what it means for a bulb to "turn on". Putting current into a wire will also put a temporary tiny current spike into any adjacent wires. But that's it until the main current gets all the way around the loop.
that's quite misleading.

In the california bay area, the beautiful 2000 year old redwoods were almost completely exterminated to rebuild after the 1906 san francisco earthquake.

The regrowth pattern was usually a group of maybe 7 redwoods sprouting around the stump of a former giant. They compete with each other are not and will not replace the tree that was cut down.

It is sad to hike around the hills, see this pattern and wonder what the big one was like.

There are still some amazing old-growth giants, say in Henry Cowell state park. Just walk around there for an hour and your viewpoint on old-growth will probably change dramatically.

The really big ones in Big Basin State Park burned in the fires, and although they are huge, they are very black and much has been lost.
I remember excited by the brith of ARM desktop capable systems. Sadly the industry chose not to standardise and I have given up on ARM desktop and even Single Board Computers. SBCs have been replaced by x86 boxes. x86 is a breath of fresh air with mainline kernel support, loads of features, support just about every device imaginable and efficiency is quite good on the lower end CPUs.

Certainly most particulate matter, and it's not even close. Comparing particulates to gas emissions is difficult, so there's no way to say what's "most".

Either way, my greater point still stands: switching to EVs isn't a cure-all to breathing around cars.
This is great but may ultimately be useless, because the storage industry has a long history of not obeying SCSI/IDE/SATA/NVMe commands around flushes and lying to the OS about when data has been committed to disk. You can't trust a drive to write stuff when you tell it to, even when you tell it REALLY NO, SERIOUSLY, WRITE THAT SHIT DOWN NOW...and certainly not in the order you tell it to.

Long ago an Apple engineer told me that one of the reasons Apple sold 68k Macs with Apple-branded SCSI hard drives (and disk utilities that wouldn't work with non-Apple drives) and continued to use Apple-branded drives well into the PowerPC and IDE era was because Apple had been burned by writing operating system / filesystem code that took what drives reported at face value and assumed they were doing what they were supposed to according to the specs for the interface standard they'd supposedly been certified to meet.

Sure, it also enabled markups, but it wasn't just about having a big margin on storage, and there are additional costs involved. It's also why often Apple/Quantum drives were slower - they were actually doing what they were supposed to be doing, whereas everyone else as doing what was fastest to juice reviews, and magazine reviewers were either too cozy with manufacturers, or too lazy/stupid, to actually test to see if a drive was doing what it was supposed to be doing.

The groups behind the interface standards? Trademark money printer go brrrrrrrrrrrrrr. Those golf balls and yachts and supercars aren't gonna drive themselves.

And yes, this has persisted into the age of NVMe flash. Power failures with SATA and NVMe flash drives can be a real risky business, because the controller is shifting data every which way. From OS memory (some NVMe drives use host memory for caching at the hardware level, which is real snake-oil salesman shit Barnum would be proud of) or drive RAM, SLC mode short term storage, and higher level cells (MLC, QLC, etc.) And the controller has to keep track of all this, in addition to its tables providing the mapping between what the OS considers physical blocks and where those blocks are actually written, due to wear leveling.

A power failure with an SSD can potentially brick the drive, (effectively) permanently.

Do reviewers test for this? Nope. Most of them didn't even realize manufacturers were sending higher-spec NVMe drives out for review and in initial distribution, and then very quickly shifting to much cheaper controllers and flash, or they were in on it and kept their mouths shut so they didn't lose access to review sample hardware.

Do not trust your storage, at all. Fault tolerance, backups, and power protection suitable for the importance of the data...
Depends on whether the systems you're working on have catastrophic failure modes, or not. In terms of how the responsible parties behave in both realms, it comes down to whether the costs of catastrophic failure can be externalized or not (e.g. government bailouts for chaos in in subprime mortgages or natural gas futures markets, Price-Anderson indemnity for nuclear reactor meltdowns). Miscalculation (see Boeing) can be disastrous.

Now if you can't externalize the costs of catastrophic failure, that will be the fundamental constraint on your engineering / finance strategy. If you really don't want your network to be breached, you'll build it around security features, not try to hack them on after the fact. I like to think SpaceX, as a private company without the kind of political heavyweight backers that ULA enjoyed, thus put a lot more effort into avoiding the kind of problems ULA is currently having, for just that reason.

Conclusion: take away the government safety nets, and both engineering and finance will perform better? Now about Silicon Valley Bank...
That's just moving the problem around. Say the RNG is controlled by a soul of some kind; next up, how does the soul work? It's either random or an algorithm, and either way we're right back where we started.

I dunno, I think it’s worthwhile to acknowledge that this describes the (very?) shallow end of the pool but these language game land wars are profoundly uninteresting to me.

This–and TWIM jhanas in general–certainly involve the arising of the relevant jhana factors. People feel real and somewhat life-changing experiences of piti, sukha, equanimity… are those, due to limited concentration, below some critical threshold to earn the name “jhana”? Sure there are reasonable arguments for this position but it’s just a language game. Both strong and weak versions of these states are real phenomena that lead to increases in wellbeing.

Besides, it’s not even entirely clear that the earliest texts are actually describing something all _that_ much more concentrated than Nadia does, although the later visuddhimagga most certainly does, and those teachers certainly teach it.

I’ve heard some teachers contrast Sutta-jhanas to visuddhimagga-jhanas and I think that’s a reasonable distinction.

The likely reason the cancer is transmittable at all is due to underpopulation/genetic bottleneck. Animal immune systems usually have no problem recognizing and destroying cells from other individuals, even cancerous ones, but you need sufficiently distinct immune markers on your cells for them to recognize as "foreign."

> Are they savvy enough to figure out you wouldn't give them a large enough mass raise, but would raise the suggested tip levels and pass the issue on to the customers?

They're likely savvy enough to know that if I can cashflow what would have been the tip, it works in my favour. There is good reason the workers (and, quite often, customers!) prefer to keep it a separate transaction. Sucks for me, but what can you do? You don't have a business without staff (and customers). They hold all the power.

> Are they savvy enough to rig things to get a higher tip, even though the overall effect is worse for the restaurant?

No doubt to the extent that it is to their favour. They most certainly aren't there for my benefit.

> Are they savvy enough to avoid getting a "worthless, over priced college degree", as richrichie suggests is the fundamental issue?

Perhaps, but pursuant of a degree is always done for the feel good emotions, not rational decision making. Not even the savviest person alive is able to keep all emotions at bay. Sometimes you just gotta spend money to get laid.

> Is this request for higher suggested tip rates because they "now are "highly educated" with expectations"?

Well, if we look to the historical record it does not appear that servers always had savvy, but that the rise of savvy people taking serving positions has raised the bar (although that could be the result of not having good data rather than some actual change).

What we do know is that colleges flat out won't allow anyone without savvy into their halls, going to great lengths to banish anyone who might try, so as a result there is a strong correlation between having savvy and having college debt. Did savvy people start taking serving jobs because they had to in order to service the debt? It is quite possible.

> That is, everything you say can be true, but not at all support richrichie's (deservedly, IMO) downvoted comment.

Okay....? That's fine. I couldn't care less about what richrichie had to say, and I care even less about someone pressing an arbitrary button that does nothing.

> Your response also sounds like I am correct

Let's hope. As long as it isn't me that's correct. I can think of nothing more defeating than spending all that time writing comments, and then not being able to learn anything from it because I was already correct.
Linux has a feature called 'binfmt_misc' which allows you to associate an interpreter to run when a file of any arbitrary format is invoked like an executable. You have to tell the kernel which extension or format is associated with which interpreter, but this is easily done in a startup script.

You still have to say '.py' at the end, though.

Pretty much my experience as a frontend guy that had to fill in for a team reduction and had to start working on the Rails side of things. I always felt like I was just having to "know" what was going to happen. Unit tests, mocks, etc. were all coming back "ok" but there was always something in production that would act up. I had never this happen with the Java and PHP backends that I always had to touch up when there wasn't much talent available. Before I was let go from the Rails client I suggested that they invest in property based testing for all code as it was quite clear there were cases that weren't being thought of that existed in the application somewhere (undocumented, manually added, etc.).

And as for consequences I do not think the West would do anything about that.

The worst outcome of nuking Ukraine for Russia is to get even more economic sanctions, that's all.

The response won't be nuclear, per its stated posture on this. But it's hard to imagine the United States would do basically nothing of substance in response, and it hasn't ruled out a violent conventional response. And at least back in 2022, Biden took care to put this messaging out indicating there would be a "consequential" response, per his interview with Scott Pelley:

"And I wonder, Mr. President, what you would say to him if he is considering using chemical or tactical nuclear weapons?"

"Don't. Don't. Don't. You will change the face of war unlike anything since World War II," Mr. Biden said.

When Pelley asked what the consequences would be if Putin crossed that line, the president wouldn't say.

"You think I would tell you if I knew exactly what it would be? Of course, I'm not gonna tell you. It'll be consequential," Mr. Biden said. "They'll become more of a pariah in the world than they ever have been. And depending on the extent of what they do will determine what response would occur."

US won't go on full scale nuclear war with Russia over some insignificant country at the end of the world

First, while it isn't a NATO partner or of similar status, Ukraine is absolutely not "insignificant" to the at least the current administration in the U.S., and the whole Atlanticist crowd. It would not have stuck its neck out (and expended its political capital) as far as it has on Ukraine's behalf thus far, if that were the case.

And while it won't go nuclear over Ukraine -- it is definitely concerned about its strategic posture and global stability, and the detrimental consequences of giving Russia perceived "pass" to use nukes in any offensive context. And would basically have to make some kind of genuinely serious response. Which some people close to the administration have quietly hinted could be a conventional military response.

Thanks for the explanation, however I was more curious about why ARM would have an advantage over x86.

I think the sibling comment explains it - x86 makes memory consistency promises that are increasingly expensive to keep, suggesting that x86’s future success might be limited by how much it can scale in a single package.
Since people in the early days of React would ignore errors thrown by components (or the React library itself) and constantly run into literal undefined behavior, React eventually adopted a behavior where it unmounts the VDOM to catch the developer's attention.[0] When a component throws an error, React will unmount to the nearest error boundary. By default, this is the root of the tree. You can control how much gets unmounted with error boundaries.

I've never used Vue so I have no idea how error handling works there, but React also offers programmatic ways to recover from errors (e.g. error boundaries can retry rendering the failed component with different state or props). Doesn't sound strange to me.

> The boundary is fuzzy, engineering is heavily influenced by finance, otherwise it's just a hobby.

This rings true for me. I'm interested in learning things, e.g. how processes work in Windows NT kernel, or how to write a custom memory allocator, instead of creating a product. I do have some passion for a certain product but it is highly personal and won't be shared.

Ripgrep is definitely much more usable than legacy grep though.
In general, the wireless handshake on G5/LTE/Wifi/Starlink will dwarf the traffic of sensors for power use. For old-style satellite mailboxes, the traffic is better batched in 45min chunks anyway (the 5W transmitters are usually only active for well under 20 seconds per message, and use a super-cap to handle the RF power draw spike.)

Naive UDP protocols have reachability problems in numerous scenarios, variable costs can balloon (concurrency with polling links is dumb), and can open a hole in your infrastructure at scale without special equipment mods. Only if you have a tier 3 or better WAN trunk or cloud-center should you even consider something silly like QUIC.

YMMV, and I love the AstroTurf on YC... lol ;)
