> is at a historic minimum that is destroying tons of long term scientific and educational initiatives.

Education was always shit. I live in Argentina, the PISA results from last exam are demential and I doubt they can get worse, don't lie to people please. There's absolutely no way in the world education can get to today levels in one and a half years of Milei.

> Roads are falling apart in a gigantic country

Roads were NEVER good, either you don't live in Argentina and you definitely can't have an opinion, or you live here and never left your house. Again, please don't lie to people, we have been living in hell for 20 years, nothing breaks like you say in one and a half years.

> and what’s left of rail is being scrapped for parts and sold to private entities that will let rails decay just like everywhere else where it was privatized.

Whoa you have a crystal magic ball? The kukas governed for 20 years, don't tell me all the railroad system decayed exactly when Milei assumed...

Is this only at the level of visual compression? For example, are there any applications in terms of understanding (being able to represent the actual meaning it stands for) and reasoning? Technically, it seems to have no connection with current reinforcement learning and other techniques. The model is quite small, yet there appears to be no explanation regarding its understanding capabilities. If it is merely for compression, what impact will it have on the current large models?

Interesting. That was not my perception of Sun at all. “The network is the computer” was a marketing campaign. Java was a language developed for IoT/toasters, and then hard pivoted to a write once run anywhere weblet language (ultimately to be replaced by a guy who threw together an integerless programming language that sounded like a skin condition, renamed to ride the crest of energy sun marketing money threw at things).

Sure, Solaris was rock solid, but it was also pretty conservative in its march forward as a Unix, being ultimately trumped by Linux.

Sun had an amazing team of people that worked on Self project led by David Ungar and others (Lars Bak who helped give us V8). They let the whole team go, who then went off and did sime cool things with dynamic optimization, which Sun ultimately ended up hiring/buying back to create the HotSpot VM.

Any NIH and other dysfunctionality went far beyond the engineers at Sun.

I'm stealing your thread to ask a question: How would you explain what an API Client is to someone who's never used one before, and has always just consumed/produced/tested API's the old-fashioned way?

Is it basically "an IDE for playing with API's"?

Is it only for HTTP-based API's?

Does it come with canned functionality for popular services out there?

I read this but still don't feel like I fully understand what it does https://www.postman.com/api-platform/api-client/

EDIT: This blog post https://schier.co/blog/call-for-beta-testers made it click a little better: "...app that makes testing REST APIs super easy"

It seems amazon itself is aware of this issue. The linked engadget article even mentions this:

> "The rate at which Amazon has burned through the American working-age populace led to another piece of internal research, obtained this summer by Recode, which cautioned that the company might “deplete the available labor supply in the US” in certain metro regions within a few years."

I wonder if any bank executives are regretting their past political choices, now that they're getting "if you know what's good for you" demands to bail out friends of Trump by propping up those friends' investments in Argentina.

Concurrently, I imagine some Treasury staff are nervous about similar demands to "help out" from up in the org-chart. Using US government assets for private gain without Congressional approval is often 10-years-in-prison territory. (Ex: 18 U.S.C. § 641 and nearby sections.)

One piece I'd like to see more clarification on is, is he doing multiple samples per pixel (like with ray tracing?). For his 1280x720 resolution video, that's around 900k pixels, so at 30Khz, it would take around 30s to record one of these videos if he were to doing one sample per pixel. But in theory he could run this for much longer and get a less noisy image.

I find it interesting that a project like this would easily be a PhD paper, but nowadays Youtubers do it just for the fun of it.

> I've seen Claude Code literally just give up on a hard problem and tell me to buy something off the shelf

I've been seeing more of this lately despite initial excellent results. Not sure what's going on, but the value is certainly dropping for me. I'll have to check out codex. CLI integration is critical for me at this point. For me it is the only thing that actually helps realize the benefits of LLM models we have today. My last NixOS install was completely managed by Claude Code and it worked very well. This was the result of my latest frustrations:

https://i.imgur.com/C4nykhA.png

Though I know the statement it made isn't "true". I've had much better luck pursuing other implementation paths with CC in the same space. I could have prompted around this and should have reset the context much earlier but I was drunk "coding" at that point and drove it into a corner.

I used to use all kinds of color schemes like the author points out, and I agree that over time I found it to be /harder/ to understand what was going on that it being helpful.

I've also used mostly a light theme (that's pretty stripped down too) for the last ~7 years, https://github.com/liamgriffiths/vim-colors-plain - it's a fork of another color scheme that I've adapted a little for the languages I work with more often. It uses bold for keywords, muted/italics for comments, and a color for constants (strings, numbers, "symbols"). It's super simple to maintain. Shout out to the original author (thank you!)

I quite like not having so much noise and it helps me focus on reading and understanding the code instead of getting distracted or mislead by the colors.

The bold is helpful to get the "outline" of structure and easily see the reserved words and it helps to not accidentally use one as a function or variable name. The colored constants are nice to stand out a little more from regular code and track them down. And at least for me the code I work in has so few comments that it's just very obvious when they appear.

Since I tend to work in relatively brightly lit environments using a light theme is just easier for me to read and switching back and forth between websites and other things it's not so jarring since most interfaces are light-themed as well.

Reading through this article made me think a little bit more though about whether there might be some new improvements I could make that would help. I hadn't given my color-scheming much new thought in a long time. I liked the idea of giving some background color to text colored on a background where the contrast would impair legibility. Given so many of us here spend an incredible amount of time reading text on a screen I think it's worth making it something a bit more enjoyable whether that's the typography or colors - it makes a difference!

To clarify, most of CDO (Consumer Devices Other) does run on AWS in the sense that NAWS is the target state, MAWS is legacy and actively (slowly) being migrated off of. CDO (including Alexa) has been using DynamoDB/Lambda/Kinesis/SQS etc forever, its just the compute and kind-of network layers that are still MAWS. Even then, a large part of CDO has moved from Apollo to ECS/FarGate/whatever unholy Hex or DataPath thing they're pushing these days

I think we need Wikipedia competitors.

Wikipedia is a victim of it's own success, it was excellent at avoiding bias for quite awhile and the vast majority of articles are extremely well written.

However it's massive popularity and dominance have also led to, well this guy put it best: https://en.wikipedia.org/wiki/John_Dalberg-Acton,_1st_Baron_...

Argentina had a persistent history of coups, dictatorships, and unstable governance before and after Peron.

It does a disservice to both Argentine and American history to compare either when their institutions historically and currently are not comparable.

This is why it is best to look at Brexit. You might be a boomer, but Brexit happened almost a decade ago, and the shakeup that happened in 2016-22 is enough data to understand how similar shakeups would impact a state with similar institutions like the US.

Wrong. It merely depends on whether the local policy maker before computer age prioritize reducing illiteracy and convenience over other considerations.

Macau, HK and Taiwan uses traditional Chinese character.

Mainland China, Singapore, Malaysia use simplified Chinese character.

Japan uses its own version, some simplified, some traditional, and also invented over 100 Japanese-made-Kanji following the same logic how Chinese characters are formed.

As a matter of fact, simplification of Chinese characters started when KMT/Republic of China was in control of the whole China. Politics gets in the way later and RoC stopped this simplification process while PRC kept it going, Macau & HK were not involved since the Portuguese and British colonial government doesn't care. Singapore and Malaysia pick the simplified version out of convenience.

> the government gives me free housing, my children get free education and free healthcare

None of these are H-1B perks. (Note: H-1B, not H1-B. It comes from ¶ H(1) of the INA of 1952; H-1A for nurses and H-1B for non-nursing specialty occupations [1].)

Immigrants pay for housing in homes that pay property taxes that fund public education. Their employer pays for their healthcare that costs multiples what most of the same treatments and drugs cost in India. (Only once they become a resident alien do they qualify for marketplace subsidies.)

> native Americans, who could even very well be the descendants of the founders of America

You've got to be shitting me. (Try native born next time.)

> my foreign children get preferential treatment in Indian universities

The students of H-1Bs (from India, no less) do not get preferential treatment in American university admissions. If anything, it's the opposite. It's why Indian Americans join lawsuits by Asian and White Americans around removing race considerations from college admissions.

I think the major difference is whether or not the machine weighs the bagging area. When it's not weighing it, you can scan fast and any weirdness is ignored. If it does check the weight, you have to not only deal with wrong weights in the system but also moving anything around or very light items will trip the alert. Generally the nicer the neighborhood, the better chances you'll have finding a non-weighing self-checkout.

I'm not stupid, I know why these measures exist but there's likely a smarter way to let the small things go. Find a way to add percentages to the alerts so that it won't trigger if I rearrange the bags. Factor in the price of an item as well so that it's triggering on meat that doesn't weigh right versus a can of beans.

Thanks, I'll give it a shot. I wish your site would show me what it actually looks like. It's a lot of words and fancy marketing images and I have no feel for the product. It leaves me unsure if I should invest my time.

I'd love to see a short animation of what it would actually look like to do the core flow. Prompt -> environment creation -> iterating -> popping open VSCode Web -> Popping open Cursor desktop.

Also, a lot of the links on that page you linked me to are broken:

* "manual edits and Ona Agents is very powerful." * "Ona’s automations.yaml extends it with tasks and services" * "devcontainer.json describes the tools"

There are no hard rules; use principles flexibly.

That being said, there are some things that are generally true for the long term: use a pinned thread per core, maximize locality (of data and code, wherever relevant), use asynchronous programming if performance is necessary. To incorporate the OP, give control where it's due to each entity (here, the scheduler). Cross-core data movement was never the enemy, but unprincipled cross-core data movement can be. If even distribution of work is important, work-stealing is excellent, as long as it's done carefully. Details like how concurrency is implemented (shared-state, here) or who controls the data are specific to the circumstances.

Good points. Thanks for the reference to Coz.

One of the researchers behind either rump kernels or unikernels talked to us here about making it usable. He said he was discouraged by his advisors from doing that. He could write more papers instead.

The reason they think that was is it's quantity over quality in much of academia, esp citation scores and funding for new research. Some groups seem to have their researchers use some of their time to build useful software. Most isn't production quality or maintained because they're basically paid not to do that. It's why many don't join academic research and others supported funding cuts or reform.

This statement in the YouTube example is unfair: "Users may expect that the video has proper access control restrictions"

The selection is clearly labeled as "Unlisted", which I find pretty easy to understand. It's a term used on other sites as well (eg. Imgur) and is hopefully becoming colloquial. For those less certain, a tooltip with more detail about the implications could easily be added.

Please don't wall your gardens behind logon credentials. Too much of the web has already done this.

Obviously sensitive things like billing should be subject to strictly controlled security. But being able to share semi-private media in a low friction-way without forcing consumers of your content to log in or create an account is extremely handy.

I like natural keys... if you can prove that they're actually immutable and unique for the thing they're representing. Credit card number is a decent natural key for a table of payment instruments, not for users. Even for a natural-key-believer, users pretty much always need a synthetic ID, because anything you might possibly believe to be constant about humans turns out not to be.

Building your rocket to survive the upchucker costs more than the savings from being upchucked.

Chuckers are the optimal large scale solution for airless bodies, but they're horizontal. You spread the acceleration out over a very long distance so you don't need a super beefy spacecraft and your humans won't turn to goo. Basically, a maglev train except it has track above as well as below and it doesn't have a maximum speed. Wrap one around the lunar equator and it can eject anywhere from sundiver to interstellar escape with human-tolerable acceleration.

Their advertised sensitivity and specificity put them in the ballpark of what other liquid biopsies advertise. The ones I know of target high-risk cohorts where the benefits of other screenings already outweigh the risks of taking them. It doesn't make sense for the average person to be getting periodic full chest CT scans for instance, but it might for a decades-long smoker.

This reminds me of the “battery bucks” design philosophy at Tesla, where a part could be as expensive as an engineer wanted if it increased range by at least that much cost in batteries. This was responsible for, among other things, monobloc brake calipers on the model 3 because it retracted the pads faster than a sliding piston caliper.

DynamoDB is used *everywhere* in AMZN Retail, this is absolutely not surprising. Plus the vast majority of internal Services are using EC2 in the form of Apollo/ECS. So OP probably hit some parts of the site that are hosted in us-west-2. For all I know they started routing all requests for us-east-1 traffic to other DCs, figuring latency is a fine trade-off for availability

If you restrict yourself to all variants of x86 and ARM, the number of high bits for which I could not find conflicting uses is 6 bits (bits 57-62). The other high bits are reserved in some hardware contexts and therefore may create conflicts.

Using 16 bits may be risky on recent x86. For example, IIRC Linux enables 5-level page tables on microarchitectures that support it, which can put valid address data in bits 48-56.

There is no guarantee that those 6 bits are safe either. They are just the only bits for which I could not find existing or roadmap usage across x86 and ARM sources when I last did a search.

I always wondered/wanted to play with a language that comes between Assembly and C (in terms of power/control, granularity, and also ease of use):

* Be just like Asm in every way, but:

* Have standardized architecture-agnostic mnemonics that translate to CPU-specific ones: like something that stands for both MOV on Intel and LDR on ARM.

* Take care of common boilerplate like function call rituals, or the multiple instructions required for loading 64-bit numbers on ARM.

Basically a real language like the ones in "programming simulation" games.

Yup. Look at the launch trajectory of the Webb telescope. The upper stage engine was too weak for the orbital insertion and the booster had to waste energy putting it higher than need be so the upper stage engine had altitude to trade for time to keep the telescope from hitting the atmosphere.

But it was the optimum solution because that engine had a long burn to take it to L2. Hauling less engine to L2 was worth more than the loss of the engine not being powerful enough to fight gravity.

Honestly I think if we each wrote a nice personal letter to Keysight they’d probably gift him one in exchange for the YouTube publicity. Several other electrical engineers on YT get free $20-50k keysight scopes not just for themselves, but once a year or so to give away to their audience members.

And yes, this person could make use of it. His videos are among the highest quality science explainers - he’s like the 3B1B of first principles in physics. Truly a savant at creating experiments that demonstrate fundamental phenomena. Seriously check out any of his videos. He made one that weighs an airplane overhead. His videos on speed of electricity and speed of motion and ohms law are fantastic.

As a tool, it could be useful as a starting point (a way to get your creativity going), but the sound is completely wrong.

Early Udio generated songs when run through a stem splitter were horrible to listen to and you could hear how it was just generating the frequencies with none of the texture—like a simulation of the frequencies an instrument would produce.

At the very least they should be re-recorded with real instruments and vocals or using the existing digital tools. Slop is one word; I like to use mush, as that is what it sounds like when you really listen closely.

I'm a tedious broken record about the fact that the base rate of most cancers means that extraordinarily-accurate-seeming screening tests have surprisingly untenable false positive rates. Like, a 99% accurate test for liver cancer might be almost worthless: because the base rate is so low, 99% of positives will be false.

And a false positive screening result is not innocuous: it incurs costs in a variety of different ways, including human health.

Exactly — the filter is only half the equation. Without a value system to guide classification, even well-curated inputs can lead to misaligned priorities. I think that’s where most people struggle: not just in filtering noise, but in knowing what matters to them long-term.

In finance, I’ve seen this play out when people chase trends without anchoring decisions to personal goals or values. That’s why I’ve been exploring ways to build tools that help users define their own “signal criteria” — not just what gets through, but why it’s worth acting on.

Would love to hear how others have built or discovered systems that help with this kind of value-driven classification — whether in news, tech, or life.

A lot of actual racists nazis hijack the anti-illegal-immigrant sentiment. I get that it's illegal, and every US administration has enforced it strictly (despite popular rhetoric).

But, the value illegal immigrants bring to the US economy cannot be understated. Purely from a economic standpoint, illegal immigrants are a huge asset. There are other portions of the population that are largely a liability.

It's not like illegal immigrants are taking skilled work americans could be doing. And let's be honest, even without illegal immigrants, a lot of unskilled work will be replaced by AI/automation.

I personally, have no problem against humane and lawful enforcement of immigration laws. But given that it is a determent to the economy, perhaps more serious and concerning crimes should be enforced? Perhaps the targets should be employers of illegal immigrants? Perhaps zip tying children and locking them in cages and denying them basic hygiene is not the right approach? I think the details is where it gets controversial, most sane people would agree that laws should be enforced.

Hilariously he's talking about Londinium, a city founded and administrated by non native non British people as part of a foreign beachhead of control by a non British empire. "Native Britains" were excluded as residents or in tiny numbers for four centuries.

London has always been a hive of culture, he's just pining for the nostalgic times he wore onions on his belt and was blind to the depth of culture in London.

There have been Russians in London since before the USSR, not that DHH would have noticed unless they spoke given so few of those Russian were Asiatic or from the steppes.

His point was that he has now finally noticed changes and that he's had his eyes opened by the likes of Stephen Christopher Yaxley-Lennon, Andrew McMaster, Paul Harris, Wayne King, and Tommy Robinson.
