This is untrue, algorithms measure time complexity classes based on specific operations, for example comparison algorithms are cited as typically O(n * log(n)) but this refers to the number of comparisons irrespective of what the complexity of memory accesses is. For example it's possible that comparing two values to each other has time complexity of O(2^N) in which case sorting such a data structure would be impractical, and yet it would still be the case that the sorting algorithm itself has a time complexity of O(N log(N)) because time complexity is with respect to some given set of operations.

Another common scenario where this comes up and actually results in a great deal of confusion and misconceptions are hash maps, which are said to have a time complexity of O(1), but that does not mean that if you actually benchmark the performance of a hash map with respect to its size, that the graph will be flat or asymptotically approaches a constant value. Larger hash maps are slower to access than smaller hash maps because the O(1) isn't intended to be a claim about the overall performance of the hash map as a whole, but rather a claim about the average number of probe operations needed to lookup a value.

In fact, in the absolute purest form of time complexity analysis, where the operations involved are literally the transitions of a Turing machine, memory access is not assumed to be O(1) but rather O(n).

Super System is old, but I wouldn't call it outdated. Definitely still worth a read. The more books you've read, the bigger your tool set. The key here is that it works in both directions because each style you learn, is a style you may recognize other players using. The pitfall of Super System, is by now, everyone's read it, and it's quite easily recognized:

- limp-shoving under the gun

- always trying to go on runs

- over playing suited connectors (JTs specifically)

But, you still get the advantage of being able to recognize it. There's lots of good wisdom in there that isn't as prescriptive either. Read as many books as you can. Poker is information warfare.

> Reddit should not be considered an authoritative source. Period. At this point it's the most astroturfed place on the internet. Accounts are bought and sold like cheap commodities. It's inherently unreliable.

I don't disagree with any of this, but I'll note that in addition, it's also the most reliable place to get a general crowd-sourced opinion on the internet. There are specialist forums for specialist subjects, sure, but nowhere else delivers like Reddit does on a diverse set of topics.

Also, how much does it decrease the fuel economy of the towing plane?

I sure wouldn't want to be on a Boeing 7XX flight with one of these things in tow. Just imagine the possibility for human and machine error, the plane in tow could cause all manner of issues for the leader.

Ever tried riding a bike and towing someone on another bike or a skateboard? It's perilous. Now do it in the air. Gutsy.

No one "denies climate". Stop being ridiculous. What people deny, because there's no evidence, is human-caused catastrophic global warming.

Funny that it used to be called global cooling. Then it became global warming. And now, surprise surprise, it's just "Climate Change".

> Surely, no one will deny the climate?!

I used REBOL about 20 years for something like this, an interesting TCL-like language with a GUI built in, I found it quite charming to look at, but it was dated even 20 years ago.

HyperCard was an interesting way to do this too. Perhaps with some work to make it a bit more user friendly and less alien feeling, Smalltalk/Pharo has potential.

Right, from a 24-day old account making only right wing political comments, a comment that addresses exactly zero of the points made by the initial post.

And regarding ignoring fascism/authoritarianism, you need only look at the difference between fascist and democratic societies

In democratic societies, the three branches of govt are independent, and the branches of civil society, press, academy, religion, business, industry, finance, entertainment, sport, and non-profits are ALL independent.

In autocratic societies, the power of the government is abused to corrupt or coerce all three branches of govt and all segments of civil society to serve the will of the executive.

EVERY single move by the person occupying the President's chair and his party as been to reduce or undermine the independence of the other government branches and all segments of civil society. The party who claims to be about "free enterprise" and "free speech" is seizing ownership of corporations, directly interfering in individual hiring decisions, and even making govt threats to get COMEDIANS fired. Seizing ownership of corporations, even partially, is more typical of Communist governments than democracies.

See if you can find a single substantive exception since 20-Jan-2025 where this administration increased freedom of expression or freedom of economic action, especially when such expressions or actions were unfavorable to it.

It may affect them. I stand by that.

Since this is hackernews, I'd imagine there are a decent amount of people with low float tech stocks. Those things can be impressively squirrely. I've moved a billion dollar company 5% with a $100,000 order by being a klutz.

Granted, these situations are usually in times of market stress, but these are times when for better or for worse people do need to raise personal cash on occasion.

We are very talented at distilling the noisy information going through the web each day into lists. Let’s distill diplomatic topics and their sub topics into lists as well. Let’s keep the lists around. They should be as indefinite as the topics they trace. Do some tech-AI-open-source-local-… stuff to compile our many mouths into the lists they belong. Unstructured data-> structured data.

Compile collective thought by semantic meaning. Each person should be able to influence the whole proportional to total participants of the list.

This isn't true. It leans extremely heavily left-wing so you won't get an accurate crowd-source opinion that disagrees with left-wing politics. There are pockets of conservative views but it's generally heavily left wing and you will get banned from many subreddits if you espouse any views to the opposite.

EDIT: I don't know why I'm getting so many downvotes, nothing I said is controversial at all.

This is not OK, and the reporting is not OK.

Opening with:

> Discord has identified approximately 70,000 users that may have had their government ID photos exposed as part of a customer service data breach announced last week, spokesperson Nu Wexler tells The Verge.

Then a big PR quote, letting a potential wrongdoer further spin it.

Then closing with:

> In its announcement last week, Discord said that information like names, usernames, emails, the last four digits of credit cards, and IP addresses also may have been impacted by the breach.

This is awful corporate PR language, not journalism, on a big story about probable corporate negligence resulting in harm to tens of thousands people.

Here's the bare minimum kind of lede I expect on this reporting:

Discord may have leaked sensitive personal information about 70,000 users -- including (but not necessarily limited to) government IDs, names, usernames, email addresses, last 4 digits of SSN, and IP addresses.

I'm ready to block both Discord and The Verge.

I am probably just misguided but multiple things you say you "wouldn't call a reactivity engine" only exist to support updating DOM (reactivity) efficiently. So what would you call them? They only exist to update the DOM, which is itself the reactivity we all want. Technically you could just getElementById and update it, but react has what I call a whole "reactivity engine" to do it for you.

I switched my gaming desktop over to Linux last year.

My experience has mostly been that Linux native versions just aren't as good as the Windows-on-Proton version. (Shout out to Larian for their recent BG3 release, a much better native version.)

Totally agree that Proton only works so well because of the constant effort that Valve put into it.

Shouting at game devs to make better native Linux versions isn't going to work. What will work is that the market demographics are slowly moving over to Linux, mostly thanks to Valve, Proton and the Steam Deck.

You're reasoning would seem to imply that because the initial investment cash always ends up circulating, no value is ever destroyed. But that's obviously not how things work because value can be destroyed. Specifically, the way it works is that for example $1B is used to buy a part of the company A. $1B is then put to use and starts circulating (but also not entirely - it does indeed just largely sit in a bank account because it's hard to spend $1B that quickly).

Let's say this investment then raises the market cap of the company that was invested in by $5-10B. Loans are then taken out against that $5-10B of increased market cap. If the growth never materializes, then the investment ends up underwater and there's secondary effects that make the loan worth less than what was given; this is what the credit worthiness is supposed to measure, but with hyperinflated values and lots of money as collateral these loans are given great rates. Basically what ends up happening is extra virtual currency starts circulating mirroring the increased market cap due to that initial $1B investment. But if the return on investment doesn't materialize, this $5-10B of currency just vanishes into thin air and dwarfs the original $1B investment. Additionally, there's leveraged secondary and tertiary bets that get taken out that further magnify this circulating currency and magnifies the loss if things don't work out.

This is precisely what happened in the dot com and banking crises bubbles. These things have secondary parasitic effects that are ballooned through leveraged investments into affecting the broader worldwide economy and crossing industries and whatnot.

There's no way someone would be stupid enough to part with $x worth of product and $ 0.5 x worth of stock in exchange for $x, is there? Honestly, it's stupid to even make such an offer. What prevents AMD from turning it around on them?

> AMD: Oh, since you put it like that, why don't you pay us $x for the chips and give us $ 0.5 x worth of stock? When your market cap rises by $ 0.5 x you'll get the money for those stocks. And hell, it might even rise further, giving you back some of the money for those chips. You're really robbing me blind with this deal, you'd be a fool not to take it!

You say your team uses Sonnet 4.5 more than Opus. However, we pay $200/mo for Opus access (with the reset timer) and now you're forcing people without telling us about the changes you made to Opus usage. You want us to pay for API access, okay. I get it, you need to make money.

But in my case and most others, Sonnet 4.5 is worse than Opus on many tasks and ends up destroying the codebase in many cases. We might not be building AI core companies, but we have complex code bases too and we find Opus works better without making comically bad mistakes.

I'd highly encourage others to try out OpenAI's codex. It works better than Sonnet 4.5, and maybe on par with Opus. At least they don't knee cap usage like Anthropic.

I'm disappointed in how this whole situation has been handled/communicated.

I had an argument with someone earlier who commented on a post I'd made and was all in on the MAGA position. They accused me of ignorance and I invited them to post some video of supposedly 'war-ravaged' Portland (a phrase used by the WH press secretary recently). First they told me to go and look on the timelines of their favorite right wing influencers, and when I declined to go on a wild goose chase they followed up with a mix of invective and random factoids, like the Portland fire department responding to 9 fires in the last 24 hours. (Since I live near a fire station in a similarly sized city the idea of a few minor fires every day impresses me not at all.)

It's tedious and unrewarding, but calling people's bluff is somewhat effective.

I didn't downvote, but if I did downvote, I might do it because: middle ground is a fallacy. Or, rather, middle ground being more correct than extremes is a fallacy.

The idea that, on every issue, there are two extremes and the "right" answer is somewhere in the middle is just sort of made up. It makes a lot of sense, though.

If I say China is 1 mile away from the US and you say it's 1 billion miles away, then the answer is probably somewhere in the middle. It makes sense. Except, the middle is not constant. The middle is constantly moving. What was middle 10 years ago is no longer so. What was middle in Confucius' time is no longer so.

If you take a look at history, you'll notice the people in the middle are almost always wrong. The 3/5ths compromise is the perfect example of this middle ground fallacy. Well... that turned out to be wrong, very wrong.

It's possible NPR hasn't changed their positioning at all, but rather, the window has shifted and now what was previously middling is now "extreme". But they could have been right all along. It happens sometimes. There were people around during the 3/5ths compromise who wanted no slavery at all. They were right!

Apparently, OpenAI was in such a rush to release the Sora 2 API that they didn’t even make a playground for it, unlike their other models. To my surprise, both Fal. ai and Replicate require you to buy their credits even though it’s BYOK api (bring your own key).

So, I decided to take the initiative and build a free, open-source, client-side webapp for the Sora 2 API. You can try it at https://sora2playground.com and find the repo at https://github.com/amirzak/sora2-playground

If you like it, I’d really appreciate a star on GitHub!

>they'd throw USB sticks in the parking lot of the company they were pentesting and somebody would always put the thing into a workstation to see what as on it and get p0wned.

One of my favorite quotes is from an unnamed architect of the plan in a 2012 article about Stuxnet/the cyber attacks on Iran's nuclear program:

"It turns out there is always an idiot around who doesn't think much about the thumb drive in their hand."

That's some impressive blindness. That's exactly why the OP is stating it's unreliable. It _was_ reliable. Now it's a minefield, because trust->money.

Just like Amazon 5 star reviews. They used to be good probably until about 2012-2015 (if you stretch it). Then it became weaponized because the trust was so high. Anything with strong 5 star reviews sold.

Of course, you can "figure out" if what you're reading is trustworthy, but to blanket state "the most reliable place" - days gone to yesteryear.

And I had to come here to find out what it actually was. Why don't project pages ever actually tell you what it is, what it does and how it does it?

Half the time it's something like "Plorglewurzle leverages your big data block chain to provide sublinear microservices to Azure Cloud infrastructures"

At least this one kind of shows you having to install Windows.

The meat of the article:

> In my binary field code, I found that an 8-bit precomputation table (in that context, 224 items taking up 128 MB) led to faster computations than a 16-bit precomputation table (232 items taking up 8 GB): while the latter fit into RAM, the former could fit into cache, and the faster access time of the former was decisive.

Interesting to see some first principles thinking to back out the “why”.

Being the figurative 800-pound gorilla in the room, it seems to me that he was indeed able to put sufficient pressure on both sides to get them to agree. Obviously it's still too early to know if it will last, but if it does, and if he can then somehow put pressure to get actual normalization between Israel and the rest of the Middle East, then I would personally chip in to get him the Nobel.

I suppose it would depend on how you wanted to simulate it. In my case I was targeting taking the signal from an unmodified test instrument that thought it was talking to a CRT and using that to figure out what display it wanted. That would be equivalent to taking the X/Y/Intensity lines from the mainboard of a Vectrex and just doing what the vector scope would have done. I drilled down enough to find the non-linear, temperature dependent, curve of phosphor decay times on the CRT used in some HP gear. It was pretty wild. If you buy third party kits they don't even bother simulating phosphor. Instead they just take the signals, figure out the information content of the display, and put that on an LCD. (Monochrome generally)

I don't think you will get competitive at games by just playing it a lot. Many pro players watch other players, talk to other players, train with other pro players, are coached by other players, so they don't just play 1k hours, they learn from others that have also played 1k hours. Just like you don't get good at football or tennis just playing games, you train specific skills, get coaches, etc.

As with many other things, each strategy will take you at some point (just playing matches), and to get beyond, you many need very different strategies (learn from other players, get coaching, etc).

I have some bad news for you about news.ycombinator.com or any other web forum. Unless you actually own the web site you can be prevented from posting on a whim.

Of course, most reputable forums have policies and rules but at the end of the day these do not mean much. Who are you going to complain to if you get unjustly banned - the Internet police?

You can always start your own blog/forum/subreddit and post whatever you like.

Collusion in live poker games in casinos is not a widespread problem. There is a problem with poker where people always think they are being cheated every time they lose. If you are playing in a casino in person it is very unlikely you are being cheated. If you are playing in a regulated website online that verifies the identities of the customers it is also unlikely you are being cheated.

The vast majority of people that play poker absolutely suck and think they are being cheated because they lose money very quickly. Most bad poker players would literally be better off playing blackjack.

I don’t disagree.

But, haven’t there been bugs where operating systems will auto run some executable as soon as the USB is plugged in? So, just to be paranoid, I’d classify just plugging the thing in as “running random executables.” At least as a non-security guy.

I wonder if anyone has tried going to a local staples or bestbuy something, and slipping the person at the register a bribe… “if anyone from so-and-so corp buys a flash drive here, put this one in their bag instead.”

Anyway, best to just put glue in the USB ports I guess.

I don't know if I just became cynical and jaded, but is this really surprising to anyone in any way? Any time I give out my personal information to anyone for any reason, I basically treat it as 'any member of public can now access it'.

Even if a service doesn't have it in their TOS that they sell it to 3rd parties, they might do it anyway, or there will, sooner or later, be a breach of their poorly secured system.

To make it clear - I don't particularly blame any one corporation, this is a systemic issue of governments not having/not enforcing serious security measures. I just completely dropped the expectation of my information being private, and for the very few bits that I do actually want to stay private, I just don't, or allow anyone to, digitalize or reproduce them at all in any way.

They must be doing a very poor job of optimizing their marketing. I had a long history or ordering the same items using the same "deal", dozens of times a year. They removed that deal and my spend at McDonald's dropped 90%. I didn't place a single order for 6 months - unprecedented. Have the noticed? Have they adjusted their marketing towards me? Did they bring back that deal or offer alternative promotions on the same items? No, no, and no. The purpose of apps and big data and especially AI is to be able to achieve the goal of 1-to-1 marketing based on individual preferences and patterns. Yet it appears a massive corporation like McDonald's is unable to achieve any of these goals, it's just continuing "mass marketing" - same deals to huge portions of their customer base, without differentiation - the same as the 1990's.

I admit to being especially sensitive since I worked in personalized loyalty marketing for nearly 20 years, so failures and missed opportunities really annoy me as both a customer and practician of the art.

I owned an '86 BRAT. There was a bushing in the shifter that wore out, and you just about had to open the passenger door to pull the shifter far enough to the right to get it into reverse. A shim from a beer can will fix it temporarily until the shim wears through.

Funnily enough, I did not impress a date by roll-starting it when the starter was intermittently flaky.

Absolutely. Remember these are just tools, how each one of us uses them it's a diffrent story. A lot can be leveraged as well by adding a couple of lines to CLAUDE.md on how he should use this memory solution, or not, it's totally up to anyone. You can also have a subagent that is responsible for project management that is in charge of managing memory or having a coordinator. Again a lot of testing needs to be done :)
