> What i like about US is that compare to other countries (like for example Russia where i'm originally from) there is almost no lying and cheating here. Instead there is a respect of the law and an army of talented creative accountants and lawyers

I thought you were being sarcastic here at first because, good lord, there is plenty of corruption here in the US (though those doing it used to care more about hiding it). The US, especially in its current state, is certainly not a place I'd describe with "almost no lying or cheating". I do understand that Russia is on another level, though, given the open assassinations and doing things like what was done to Navalny.

To be fair, the technology sigmoid curve rises fastest just before its inflection point, so it is hard to predict at what point innovation slows down due to its very nature.

The first Boeing 747 was rolled out in 1968, only 65 years after the first successful heavier-than-air flight. If you told people back then that not much will fundamentally change in civil aviation over the next 57 years, no one would have believed you.

Yeah, I got gubbed everywhere in the UK as well.

When Betfair first came on to the scenes the traditional online (and offline) bookmakers were like fish in a barrel for arb bets.

I still remember when the first major bookmaker (pretty sure it was BetVictor) started tracking Betfair markets automatically. Now they all do it.

I know about the plan. But how did you make the jump from that to SSA being unconstitutional?

A plan to eliminate program that keeps 22 million Americans out of poverty most of whom are seniors is of great interest to a super-majority of voters?

Kids, this is what happens when you read far right conspiracy theory websites for news.

> The Duo launched in July the same year. Pentium D was released in May 2005, as was Athlon 64 X2.

Multi-socket machines predate these processors by at least ten years. Windows NT 4.0 (first released in 1996) had multiprocessor support, as did Linux 2.0 (also released in 1996).

If you don't want to bother verifying this information, gut-check it. Ask yourself: "Why on earth would the Masters work on adding SMP to Erlang have started in 1997 if there weren't already working computers that could have benefited from SMP? And would it have made any sense to do this work if those sorts of computers hadn't already been around for a while?"

> It’s rare (but not impossible) for a people to have been in the same place on Earth for thousands of years. It’s more like hundreds.

Is it really rare? That seems to be the norm except for America and Africa that got replaced or displaced by colonization. But in Europe and Asia most areas has been populated by steady groups. Rulers come and go, but the people living there stays the same.

I think its rare for everyone to have been there for a thousand years, but its not rare for a majority of the genes to have stayed in one place for a thosand years.

Surely someone who is signing up for an account on an American tech message board would understand the connotation that word carries in the West (and indeed in Islamic society as well, since contextual usage makes it quite obvious what's inferred and there are multiple words that could be used instead). An innocent excuse of "well in my language it just means struggle" is only going to fool the naïve.

The problem with using objects and structs in Common Lisp is the verbosity of access, or of setting up shorter access using with-slots and with-accessors.

I fixed that in TXR Lisp:

(defun time-to-move (from-pos to-pos) (max (time-to-rotate from-pos.azimuth to-pos.azimuth) (time-to-ascend from-pos.elevation to-pos.elevation)))

The remaining issues are self-inflicted verbose naming. I would make it

;; time to move (defun ttm (p0 p1) (max (ttr p0.az p1.az) (tta p0.el p1.el)))

If the entire program fits on a few pages, you can remember a few abbreviations.

The dot notation is a syntactic sugar for certain S-exps:

a.b.(c x y).d -> (qref a b (c x y) d) .a.b.c -> (uref a b c)

there exist macros by these names which take care of the rest.

Starting in TXR 300, there can be whitespace after the dot. So while you cannot write in in the popular way:

obj .(meth arg) .(next-meth 42)

you can do it like this:

obj. (meth arg). (next-meth 42)

this has a lot do with Lisp already having a consing dot.

Lisp doesn't mean being against all syntactic sugars; e.g. we mostly write 'X rather than (quote 'X).

But note that even if we don't have this notation, how the author has tripped over himself to create verbosity. After two nestings of with-accessors he ends up with:

(time-to-rotate from-az to-az) (time-to-ascend from-el to-el)

Here from-az is not a whole lot shorter than (az from)! If he used shorter names like el and az, he would have:

(defun time-to-move (from to) (max (time-to-rotate (az p0) (az p1)) (time-to-ascend (el p0) (el l1))))

Don't make names for yourself that you then have to shorten with clumsy macros that make the function longer overall.

Another thing is, why does time-to-move take two objects? But time-to-rotate and time-to-ascend work with destructured azimuths and elevations?

(defun time-to-move (from to) (max (time-to-rotate from to) (time-to-ascend from to)))

Time to rote and time to ascend could be inseparable. If the device is mounted on an incline, the time to ascend may depend on the azimuth. It may be better to rotate it first than elevate or vice versa, or execute some optimal combined motion.

The moment of inertia of the thing may depend on its elevation; it may be easier to rotate in a high elevation. So just time-to-rotate alone needs the whole object.

Is someone telling the ants how to "live life optimally"?

Did they all get wiped out after more "intelligent" species showed up?

The chimp troupe is really full of itself when it comes to thinking about "intelligence".

There are more microbes on earth than there are stars in the observable universe. If you don't know this, don't even worry yourself, thinking about anything else.

Intelligence is a side show. It's not the main show and never has been.

These are the kind of studies that make so much more sense than the "LLMs can't reason because of this ideological argument or this one anecdote" posts/articles. Keep 'em coming!

And also; the frontier LLMs blow older LLMs out of the water. There is continual progress and this study would have been structured substantially the same 2 years ago with much smaller N on the graphs because the regimes were much tinier then.

I doubt Helion will work. By their own paper using simplified model their device allows theoretically for Q no more than 2 (2 times energy produced versus energy spent). They claim with their like 90% efficient capture they still get net energy gain. But typically reality way messier than model and I will be surprised if they archive Q=1.

Tokamaks main problem is plasma instabilities. While Commonwealth may archive high Q briefly, nobody knows how plasma will behave at those conditions and long operations may not be possible.

Stellarators on the other hand do not have plasma stability problems. So my bet is on those.

If the restaurant buys e.g. a fancy oven or a delivery truck, it can't expense 100% of that cost in year 1, it has to spread that cost over the lifetime of the oven or truck.

Labor that operates the business day-to-day would be an expense, labor that creates a capital asset is more complicated.

I happen to think most employee time in software dev is more on the day-to-day operation side, and should be expensed, but I can see an argument that some should (or could) be amortized.

They're still expenses, they just now need to be amortized.

Buying a truck is an expense, as is buying gas for the truck. But the former you have to amortize over x years, the latter you can expense immediately.

The law used to be "employee salaries for software are like buying gas" and now it's "employee salaries for software are like buying a truck".

The reason for this limit, at least on modern systems, is that select() has a fixed limit (usually 1024). So it would cause issues if there was an fd higher than that.

The correct solution is basically 1. On startup every process should set the soft limit to the hard limit, 2. Don't use select ever 3. Before execing any processes set the limit back down (in case the thing you exec uses select)

As usual with these lists, they would much benefit from more in-depth explanation. This list at least deigns to link to examples for many of the claims (like a flight that leaves on time but arrives 40 hours late [1]), but doesn't explain what happened.

Having said that, many of the links are very informative. For example the crater on Mars that has an ICAO airport code [2]: "On 19 April 2021, Ingenuity performed the first powered flight on Mars from Jezero, which received the commemorative ICAO airport code JZRO."

Working with complex PDFs like user manuals, schematics, or multi-language logs? Checkout this benchmarking analysis of Retrieval-Augmented Generation (RAG) systems for Question Answering on Complex Industrial PDFs.

To support this, we built a modular ingestion and processing pipeline designed specifically for industrial documents, ranging from shift notes and engineering reports to scanned schematics and multilingual manuals.

Key contributions:

- A domain-adapted OCR + parsing stack optimized for noisy, heterogeneous documents

- Semantic chunking + entity linking, tuned for downstream QA performance

- A new benchmark: TIA-pdf-QA-Bench, which quantifies how OCR and chunking quality affect RAG-based QA

This pipeline is now available as a standalone module. If your work involves document-based reasoning, especially with scanned, structured, or noisy PDFs, we’d love to connect.

For reference, iSpace is a public company that could IPO with no record of success or profit. While I heard lots of optimism for their next try, I didn't see where it came from and now we know.

It's an example that comes up when discussing plans to make it harder to IPO and I'm hopeful things will change to make the JP market generally more attractive. For space activities, nothing wrong with chasing dreams but it really needs to be kept private IMO - there's plenty of private capital out there. The price bump before the launch and after hours collapse after the news looks more like a rug pull than anything.

Gambling should not be trivially easy to participate in. That's the real problem.

If we're pretending it's entertainment, then it shouldn't matter that winners get shut down... because it's just supposed to be fun. If we're not pretending it's entertainment, then we need to deal with the fact that it's a huge negative payoff vice we shouldn't be allowing to happen easily (make it legal and rare).

The idea that we're trying to create "fairness" in a business that basically wouldn't exist if the operators don't have a guarantee of success is ridiculous. We can either require sports betting agencies to have betting lines that require their bets be balanced or we can basically ban them from becoming a large industry.

Right, but that's a comment on yourself, even if you meant that for everyone else. Society absolutely trusts 20 somethings for sensitive data all the time.

Don't give me the bullshit about "this situation". Go to your nearest hospital and notices a sea of young nurses handling you and your family's medical data on a clipboard, paper, and a very poorly secured 20 year old workstation.

You are inconsistent, and you will continue to be inconsistent. In fact, your bank account info is known by the teller who has similar qualifications, your purchases and address is known by the customer service representative hired straight out of high school or in a call center in Egypt, and so much more.

This talking point is entirely a political cudgel that only makes sense to the kind of folk that do not think past their favorite politician's tweets. On that fact, wanna know who's been managing your letters/calls that you've been sending your politician? These ones know your phone number, and any modern filter will be looking for your address.

Ask HN: A Tetris variant with greater tactical and strategic depth?
by amichail | 2025-06-07 01:41:22+00:00
In addition to the standard Tetris tetromino colors, squares can change to gray as a result of line clears.

If a line clear occurs without the line immediately above it also clearing, any squares directly above turn gray.

Gray squares cannot be part of a line clear and hence act as obstacles to line clears.

When a line is cleared, any gray squares immediately below it are removed.

What do you think of this variant?

Transparency isn't the reason we use so much plastic. We like plastic because it is lightweight and not biodegradable. We like it because it lasts thousands of years. Because if it lasts thousands of years it will do a good job of storing your food products. Or it will stick around in various components without needing to worry about rain and such.

What we need to develop is something that doesn't degrade at all under most human living conditions, but does degrade rapidly if we expose it to some sort of not-common trigger, whether that is another chemical or temperature or pressure or whatever.

Take a closer look at that chart. Notice the pronounced downward trend on the blue line (federal) starting from a peak in 1992 and declining until the Bush administration unbalanced the budget? In 1998-2001, we had a budget surplus!

https://www.cbo.gov/sites/default/files/cbofiles/images/pubs... https://www.cbo.gov/publication/61181

The big thing, of course, is that total spending is a crude metric lumping discretionary and mandatory spending together. Federal employment has been getting a lot of attention this year, but it's at historic lows and there's no real way to significantly lower total federal spending there without cutting social programs millions of people depend on.

Genetics strongly suggest Australia was settled by a single broad wave of humans that spread across the continent, finfing their niche, and staying in place whether that be east, west, north south, across desert, coast, rivers, forrest, etc.

This contrasts to earlier "literary" arguments in magazines such as Quadrant that native Australians moved about and fought for territories with invaders supplanting original dwellers long before Europeans arrived.

Hi HN – I’m a founder and chronic illness survivor working on a platform to solve the indoor air quality crisis, starting with mold.

We’re building Moldmap, a community-powered app that helps health-conscious people find safe places to live, travel, and work—like Seed Oil Scout or Find Me Gluten Free, but for air.

Longer-term, we’re developing the world's first real-time mold sensor that can provide an immediate heads up if there's danger.

We just started fundraising and would love to connect with: • Early users (especially those with mold sensitivity) • Angels / investors in bio / health / environment • Folks who’ve built crowd-data platforms

Would appreciate any feedback or connections. Happy to share our pitch deck to serious inquiries, feel free to email me at justin@invivus.io

The brain and nervous system is just the spokesorgan for a carnival of bioenergetic centers that makes Stock Exchanges and Sports events look staid in comparison.

Modern computers are pretty great at scanning small blocks of memory repeatedly, so n^2 can be faster than the alternative using a map in cases for small N.

I spent a lot of time fixing n^2 in blink, but there were some fun surprises:

https://source.chromium.org/chromium/chromium/src/+/main:thi...

For large N without a cache :nth-child matching would be very slow doing n^2 scans of the siblings to compute the index. On the other hand for small sibling counts it turned out the cache overhead was noticably worse than just doing an n^2. (See the end of the linked comment).

This turns out to be true in a lot of surprising places, both where linear search beats constant time maps, and where n^2 is better than fancy algorithms to compensate.

Memory latency and instruction timing is the gotcha of many fun algorithms in the real world.

I generally agree that SATs and APs lose meaning once the college enrollment is behind you, though I was asked for my SAT scores by my third employer (D. E. Shaw & Co.). I had to check twice with the recruiter to be sure I’d heard her correctly that she wanted my SAT score from a decade ago. (She did.)

Probably not unrelated: DESCO was also the single highest density of talent that I’ve ever experienced post-graduation.
