Even with traffic waves, the capacity of a road is not infinite and trains beat it hand over fist, simply because of physics. Imagine a crowded highway with invisible cars: people would be sitting 30 feet x 15 feet apart. That is why there is traffic more than anything, the limits of that capacity with that really loose packing that cars enable.

Walking 30 mins from the station is no issue. Try walking through a far flung terminal at DEN or ATL or the new TBIT at LAX, you will walk 30+ mins from the gate before you hit your rideshare point I expect. Also, rail stations do not exist in a vacuum. They often interface with bus lines that go parallel or perpendicular to the rail routing, so that 30 min walk could just be a 2 min ride.

We also do have railbuilding experience in this country. LA metro has built out their entire network of over 100 rail stations within the last 35 years. This is the fastest rate of railbuilding on the entire continent, not just in the U.S., in a high land value land labor cost area to boot. As we speak multiple concurrent rail projects are being planned or actively built. Much of the build out is paid by a 1 cent sales tax measure that local voters approved with 71% in favor.

If you mean the bit about refusal from other models, then sure here is another run with same result:

Note I am using direct API to avoid triggering separate guardrail models typically operating in front of website front-ends.

As an aside the website you used in your original comment:

> [2] Used this link https://www.deepseekv3.net/en/chat

This is not the official DeepSeek website. Probably one of the many shady third-party sites riding on DeepSeek name for SEO, who knows what they are running. In this case it doesn't matter, because I already reproduced your prompt with a US based inference provider directly hosting DeepSeek weights, but still worth noting for methodology.

(also to a sceptic screenshots shouldn't be enough since they are easily doctored nowadays, but I don't believe these refusals should be surprising in the least to anyone with passing familiarity with these LLMs)

---

Obviously sabotage is a whole another can of worm as opposed to mere refusal, something that this article glossed over without showing their prompts. So, without much to go on, it's hard for me to take this seriously. We know garbage in context can degrade performance, even simple typos can[1]. Besides LLMs at their present state of capabilities are barely intelligent enough to soundly do any serious task, it stretches my disbelief that they would be able to actually sabotage to any reasonable degree of sophistication - that said I look forward to more serious research on this matter.

> Third, this is a case of supply and demand. The system is focused on the supply side composed of desperate workers rather than demand side of people who hired them for personal profit. This is silly: come down hard on one meatpacking plant and you "solve" the problem of hundreds of illegal immigrants with a single criminal charge. Trying to stamp out the immigrants one-by-one is inefficient and unjust.

A major reason ICE and a strict border exist is to depress wages and enable employer abuse. That's why this is never the approach to solve immigration problems.

Being able to say "behave or we'll deport you" is exactly the point. If you flip it around you'll quickly find a bunch of employers that cry about how wonderful these workers are and that we need to "have a heart".

Undocumented workers won't, for example, form a union or make complaints to OSHA.

I got an HP Pavilion laptop in 2011 with an intel i5-2540m, I believe, and a Radeon 6750 or thereabouts. For the first year I owned it, GPU switching was utterly broken and the dedicated GPU was basically dead silicon. Sometime in 2012, they released an updated BIOS that allowed changing the GPU switch logic from "dynamic" to "fixed dedicated", and that allowed you to actually use the builtin dGPU. That being said, the documented issue in TFA arises specifically when trying to exclusively use the dGPU...

I have been developing for 40 years as a hobbyist for 10 and a professional for 30. I always started with the happy path and made it sure it worked and then kept thinking about corner cases. If an LLM can get me through the happy path (and it often generates code to guard against corner cases) why wouldn’t I use it?

> I don't think it is normal to follow the flow assuming nothing has happened.

I think it is for situations where the programmer wants to check a child property but the parent object may be null. If the parent is expected to be null sometimes, the syntax lets the programmer express "try to get this value, but if we can't then move on" without the boilerplate of explicitly checking null (which may be a better pattern in some cases).

It's sort of like saying:

- Get the value if you can, else move on. We know it might not be there and it's not a big deal.

v.s.

- The value may not be there, explicitly check and handle it because it should not be null.

> View counts are for monetization

Agree, however view counts, i.e. metrics tracked by YT, or by sponsors,creators in fancy dashboards isn't the view counter we are shown and nobody is questioning how those are implemented. The View Counter means very specific UI component in YT interface shown to regular users.

> view counter isn't for you

Disagree,

View counter is a important decision making input along with the thumbnail, title and duration of the video on if a user will click on the video to watch them.

It is in effect an advertisement for the video.

If that wasn't the case, then YouTube wouldn't be showing them in every list view and next to every thumbnail. When the numbers no longer represent what the users think they represent I would say it is not far from false advertising.

A fair amount of people on here and I have both YT Premium and also use some adblocker, should our views be counted or not according to this point of view? .

And then kiss the US auto industry goodbye. It's hard to know what Trump is serious about - other than lining his own pockets - but if he's serious about restoring manufacturing jobs in the USA, that's a non-starter. And oh, wait, there's that other thing he's serious about - maximizing oil company profits - and great Chinese EVs for $15K or less are the stuff of oil company executives' nightmares.

Yes exactly.

Also to a certain degree you can just throw loads of GPUs at the problem.

So instead of 100k GB200s, you have ~1m of these cards. One thing china _is_ good at is is mass manufacturing.

There's all sorts of caveats to that, but I really think people are overlooking this scenario. I strongly suspect that they could ramp output of (much?) weaker cards far quicker than TSMC can ramp EUV fabrication.

Plus China has vastly superior grid infrastructure. They have a massive oversupply of heavy industry, so even if they hit capacity issues with such gargantuan amounts of cards I can easily see aluminium plants and what not being totally mothballed and supply rerouted to nearby newly built data centres.

No, it's not about the companies, it's about the government that allows those companies to behave the way they do. Which is why the article is about the US and not about Walmart or Dow Chemical.

Companies will almost always look for ways to extract maximum profit even if it comes at the expense of others' wellbeing. So it is up to government to protect its citizens by regulations that prevent, for example, polluting water supplies, the air we breathe, etc., or from taking advantage of consumers, defrauding them, etc.

If government decides to roll back many of those regulations (like gutting the CFPB), then companies are free to engage in those destructive practices.

You can blame the companies, sure -- but mostly I blame the government (and those who voted for that government) because it's their job to keep companies in check, and instead of doing that, they're in bed with the companies, and even directly profiting from them (also known as corruption, which oligarchies do very well).

Appreciated the response! I noticed the same when I ran tau2 myself on gpt-5 and 4.1, where gpt-5 is really good at looking at tool results and interleaving those with thinking, while 4.1/o3 struggles to decide the proper next tool to use even with thinking. To some extent, gpt-5 is too good at figuring out the right tool to use in one go. Amazing progress.

The teams we beat trained as individuals and were selected competitively against each other as their school's "best 3".

We were "just" three friends who had studied together for 4 years, knew each other's strengths and weaknesses intimately, and then for the comp trained intensively on optimising the "parallelization/scheduling" aspects (as you put it) to get the best score in the minimum time. That included both the logistical and mental aspects of recovering from setbacks midway through the 5 hour problem sets.

During the finals, you'd be surprised how many teams' teamwork we saw fall apart when three very smart people under intense time pressure hit unexpectedly failing submissions with the bottleneck of a single computer. ICPC is a genius format.

- Multi-rename tool.

- Synchronize directories (symmetric and asymmetric, with subdirectories).

- Background operations.

- Operation queue (so that you don't thrash disks while doing many operations).

- Start menu.

- Displaying directory sizes easily.

- Great file search.

- Diff viewer for text files.

- F3 quick file viewer.

- Compare directories.

- Plugins.

Those are my favorites.

Obviously, but Hamas needed Israel's help to maintain power, which Israel was happy to do. This happened recently, like in the 2020s. In case there's a paywall preventing people from reading my sources, here you go:

> Most of the time, Israeli policy was to treat the Palestinian Authority as a burden and Hamas as an asset. Far-right MK Bezalel Smotrich, now the finance minister in the hardline government and leader of the Religious Zionism party, said so himself in 2015.

> According to various reports, Netanyahu made a similar point at a Likud faction meeting in early 2019, when he was quoted as saying that those who oppose a Palestinian state should support the transfer of funds to Gaza, because maintaining the separation between the Palestinian Authority in the West Bank and Hamas in Gaza would prevent the establishment of a Palestinian state.

I got a Bambu P1S two years ago for Christmas as a gift. It's been fantastic. 98% of my prints have been successful.

They aren't the free open source dream machine, but it also works quite well and needs little messing with.

I've played with 3d printers back to the RepRap and Makerbots - but those always required so much work to get a successful print.

I haven't seen something clearly better in the price range.

With all due respect to the Anthropic team, I think the Claude status page[1] warrants an internal code red for quality. There were 50 incidents in July, 40 incidents in August, and 21 so far in September. I have worked in places where we started approaching half these numbers and they always resulted in a hard pivot to focusing on uptime and quality.

Despite this I'm still a paying customer because Claude is a fantastic product and I get a lot of value from it. After trying the API it became a no brainer to buy a 20x Max membership. The amount of stuff I've gotten done with Claude has been awesome.

The last several weeks have strongly made me question my subscription. I appreciate the openness of this post, but as a customer I'm not happy.

I don't trust that these issues are all discovered and resolved yet, especially the load balancing ones. At least anecdotally I notice that around 12 ET (9AM pacific) my Claude Code sessions noticeably drop in quality. Again, I hope the team is able to continue finding and fixing these issues. Even running local models on my own machine at home I run into complicated bugs all the time — I won't pretend these are easy problems, they are difficult to find and fix.

> Anthropic is purposefully degrading things to save money

Regardless of whether it’s to save money, it’s purposefully inaccurate:

“When Claude generates text, it calculates probabilities for each possible next word, then randomly chooses a sample from this probability distribution.”

I think the reason for this is that if you were to always choose the highest probable next word, you may actually always end up with the wrong answer and/or get stuck in a loop.

They could sandbag their quality or rate limit, and I know they will rate limit because I’ve seen it. But, this is a race. It’s not like Microsoft being able to take in the money for years because people will keep buying Windows. AI companies can try to offer cheap service to government and college students, but brand loyalty is less important than selecting the smarter AI to help you.

The special part is the "signal handler trick" that is easy to use for 32-bit pointers. You reserve 4GB of memory - all that 32 bits can address - and mark everything above used memory as trapping. Then you can just do normal reads and writes, and the CPU hardware checks out of bounds.

With 64-bit pointers, you can't really reserve all the possible space a pointer might refer to. So you end up doing manual bounds checks.

i was curious so i looked this up: LA Metro (combined bus and rail) has a monthly ridership of like 25 million [0]. that's nearly a million people taking shared public transit every day. anecdotally, i chose to ride metro rail over driving when i had a "real" commute. lots of people do.

people in NY and Chicago are fiercely defensive of their mass transit options. the bay area would be a terrible place without BART and Muni.

for all its problems, shared mass transit is a net good and there are millions of people in this country who prefer it.

Exactly. If I'm a foreign company thinking about setting up a factory in the US, I'd probably pass.

With the tariffs it's already going to be hard to get the equipment you need into the US without spending a significant amount of money. But now you run the risk of the US arresting and deporting all your skilled workers setting up and managing that factory? No thank you.

Absolutely braindead move.

> Nvidia has the market cap of a medium-sized country

This makes no sense. Market cap is share price times number of shares, there is no analog for a country. It’s also not comparable to the GDP of a country, since GDP is a measure of flow in a certain time period, whereas market cap is a point in time measurement of expected performance.

From what the article says, this is specifically a problem when updating from an OS version released two days ago, to the other OS version released two days ago. That's not exactly the most logical or likely path for most users to take, though obviously Apple needs to be able to handle this going forward for users who are hesitant to update to 26 and want to run 15.7 in the meantime.

Hot take alert

> When is WASM finally going to be able to touch the DOM?

Coming from a web background, and having transitioned to games / realtime 3D applications...

Fuck the DOM dude. The idea that programming your UI via not one but TWO DSLs, and a scripting language, is utter madness. In principal, it might sound good (something something separation of concerns, or whatever-the-fuck), but in reality you always end up with this tightly coupled garbage fire split across a pile of different files and languages. This is not the way.

We need to build better native UI libraries that just open up a WebGL context and draw shit to that. DearIMGUI can probably already do like 85% of what modern webapps do.

Anyways .. /rant

Yes, support started for Israel once Epstein got dirt on them. There is no history of support for Israel prior to that. Yours it totally the most likely/rational take.

WTF is going on with this site? You sure have people real comfortable to say this kind of shit here.

"Never believe that anti-Semites are completely unaware of the absurdity of their replies. They know that their remarks are frivolous, open to challenge. But they are amusing themselves, for it is their adversary who is obliged to use words responsibly, since he believes in words. The anti-Semites have the right to play. They even like to play with discourse for, by giving ridiculous reasons, they discredit the seriousness of their interlocutors. They delight in acting in bad faith, since they seek not to persuade by sound argument but to intimidate and disconcert." --Jean-Paul Sartre

well this.

when I started tinkering there were none of those kits, and the Ender I have now has pretty much nothing in common with the Ender I bought back then except some parts of the frame and the drives. and still the whole journey cost was about the same as just buying Prusa and then learning nothing.

this is a bit philosophical, but when you do want to shape material, be it wood or plastic, you have to not only understand how it's done, but to feel it. or you will repeatedly end up with crap and then endlessly wonder what went wrong

this cannot be bought, it's experience. for 3d-printing the fastest way is to get something like Ender and then build your own perfect printer out of it over several years.

> you're assuming that "bank security" (or the like) will never call you to alert you to a scam, or that you will recognize their number

I'm assuming no such thing. I have indeed gotten calls and texts from my bank and my credit card companies alerting me to fraudulent transactions, that were legit calls and not scams.

But I didn't answer those calls or texts directly, or try to figure out whether the number that was calling me or texting me was the right one. What I did was to call a number that I already know, independently, leads to my bank, or to my credit card company's fraud department. Or I independently logged into the bank's or credit card company's website to see if there were any alerts. And if there were, I acted on them.

I described this in my earlier post: "If they claim to be from some company I have a relationship with, I check independently to see if something's up."

If I were to decompile the SSDTs on an affected laptop, would you be able to see if/when the system is entering SMM and what it's doing in there that's taking so long? I've noticed this issue on several Windows gaming laptops with nvidia GPUs over the years and I also started installing event tracing, the intel BIOS tools, etc, but it was all just a bit beyond my depth. I've done some DJ'ing and would like to use my gaming laptop, but the whole system freezing so hard that audio glitches every minute is probably part of why the "nobody uses Windows for live audio due to latency spikes" thing is so widespread. Not to mention it makes, you know, gaming unpleasant.

No, I don't think it will. Pointers to managed objects are opaque, and aren't actually backed by the wasm memory buffer. The managed heap is offloaded.

Shrinking the memory object shouldn't require any special support from GC, just an appropriate API hook. It would, as always, be up to the application code running inside the module to ensure that if a shrink is done, that the program doesn't refer to memory addresses past the new endpoint.

If this hasn't been implemented yet, it's not because it's been waiting on GC, but more that it's not been prioritized.

One thing that seems to link many past great civilisations is their discovery of forces or powers that eventually consume them.

The challenge seems to be how to wield the fire without yourself getting burned. Some would say this is an impossible task given the relative nature of our definitition of what is considered "new", as once again we extend our hand to the flame.

What past lessons may we bring to this experience which can allow us deeper insights, and the hope of a less destructive outcome?

What exactly are they meant to replicate other than other IQ tests? They don't make a statement about anything that is falsifiable, other than that if you give somebody who scores high on a test carefully designed and tested to match the results of previously given IQ tests when given to the same people, they'll tend to match the results that those people will get on other tests that were calibrated in the exact same way.

If you're trying to say they replicate over the lifetime of the same person, I've had a 15 point swing between tests, out of the few I've taken. What did stay constant for me from age 10 to age 40 was my Myers-Briggs test (my dad was a metrics obsessive), and that's obvious horseshit. Consistency doesn't mean you're measuring what you claim to be measuring.

edit: if it matters, scores were between 137 and 152, so exactly an entire standard deviation. That's like the difference between sub-Saharan and European that racists are always crowing about, but in the same person. IQ doesn't even personally replicate for me.

I think D4M can be the real and universal magic box alternative mentioned in the article where "magic box knows how to do only one thing: it reads from Kafka, builds Iceberg tables, and keeps them compacted" [1]. D4M can be even better than the proposed TableFlow solution because as it stands now TableFlow cannot fully perform all the listed 12 points that automates all of the annoying parts about generating and maintaining Iceberg tables. Above all D4M is founded by sound mathematics similar to SQL [2].

Sort of... No I was thinking back to 2008-2009 actually, sorry, I should have been clearer about that.

Something else most forget is that during the low (or real negative) interest rate time of the 2010s, plenty of talk about how more inflation was desired surfaced from time to time.

As others point out though, the US is a big country, with regions of economic activity. The more I learn about it, the less I know
