They could also do a private party transaction to sell the coins outside of an exchange, in order to hide the sale and also hide the price of the tokens sold.

This is common practice in the stock market, called "dark pools" [0]

> Dark pools came about primarily to facilitate block trading by institutional investors who did not wish to impact the markets with their large orders and obtain adverse prices for their trades.

> CoW is an efficiency gain.

You're thinking of the optimization technique of CoW, as in what Linux does when spawning a new thread or forking a process. I'm talking about it in the context of only ever modifying copies of file system data and metadata blocks, for the purpose of ensuring file system integrity, even in the context of sudden power loss (EDIT: wrong link): https://www.qnx.com/developers/docs/8.0/com.qnx.doc.neutrino...

If anything, ordinary file IO is likely to be slightly slower on a CoW file system, due to it always having to copy a block before said block can be modified and updating block pointers.

> And if it was still legit after that, there would be days or weeks of waiting for the transfer to actually happen

or you get a better bank to begin with

most banks that call their slow processes "security purposes" are actually just putting up barriers to maintain liquidity. the banks that go bust are the ones that got clientele based on making it convenient to transfer

Coyotes attacked a small dog in the park near my house last fall (when the juveniles leave the den and try to stake out territory) so I understand the concern. But comparing them to lions in Zimbabwe doesn’t resonate with me and I live in Chicago (we have tons, one was under my porch last year).

Think of all the samples of the interaction function between humans and the >1mm coyotes (often unbeknownst to the humans) in American cities each day. The list of all attacks recorded in modern times has a Wikipedia page. In human-created spaces we make very little separation from the habitats coyotes live in. They choose not to predate the defenseless babies they encounter in backyards because it is not the ecological niche they have carved out.

I will let my older children play unsupervised in my backyard despite knowing there are dozens of coyotes in my city because no creature has made a niche out of killing them. The same is not true for my very young children but that’s because toddlers have made an evolutionary niche out of killing themselves :)

That might be a strong argument in many languages, but in Haskell you really don't need to memorize operator precedence. In nearly every case, the types tell you the precedence. They don't literally, but most expressions only type check in one particular parse tree.

As a result, you just don't think about precedence when reading code. If you assume the code type checked correctly, you know that it all just makes sense. You don't need to create a parse tree. You just trust.

(Actually, this is the huge advantage of Haskell in most every case. You don't need to understand everything. You just trust that it does what makes sense, and you're right. The compiler enforces it.)

NVMe NAS is completely and totally pointless with such crap connectivity.

What in the WORLD is preventing these systems from getting at least 10gbps interfaces? I have been waiting for years and years and years and years and the only thing on the market for small systems with good networking is weird stuff that you have to email Qotom to order direct from China and _ONE_ system from Minisforum.

I'm beginning to think there is some sort of conspiracy to not allow anything smaller than a full size ATX desktop to have anything faster than 2.5gbps NICs. (10gbps nics that plug into NVMe slots are not the solution.)

By the way, no hard feelings.

The best thing that happened with my early projects was the local community I was able to help build here in Brazil.

I've seen many local contributors that helped with my early projects do things well beyond what their dreamt of at the time, and I'm sure I had a positive influence on the careers of many people. All with honest, simple hard work.

I am sure many people remember I did some things first, and without any investment or marketing attached to it. Just a kid, making things.

To me, that is worth a lot more than VC money.

The actual DOI link also goes to that space article on science.org. It could be just that we as well as Google only sees that but the authors saw the real paper. Of course it's part of a big load of cite-spam so even if they did read it, they probably just cherry picked something - anything that seemed to support their vague low value claim.

We saw almost 750k layoffs since 2022.

Where are all these people finding jobs? When I see r/layoffs on reddit, people are literally crying. Many are searching jobs for months and probably a year or so.

I had someone beg job to me on customer discovery call. I was really sad that person was in that state but I could not help since we are hiring for last 18 months. All job positions are fake or stale.

VCs and especially Silicon Valley juggernauts are salivating over the fact that they can have 10 people team create a trillon dollar software and thus supermaxing their investment.

If AI automates even 20% of software engineering jobs, do you think we will survive with more layoffs and downturns?

What about regular software folks, sales, and marketing folks?

I find it extremely disturbing that companies are allowed to raise in the US and then outsource jobs to India. That's how you get scamsters like Soham. Whole thing could be a manufactured PR similar to what Cluely (Chunging Lee) did.

So on one hand you have companies creating job but sending them to offhose, layoffs due to limited need for humans and cost cutting.

Starting a company is also of no use until you get funded or become hot like Cursor. For those who dont know Cursor came to fame in 2023 but they started in 2022. They are all MIT and likely very smart people who had tons of other options.

What are your thoughts as middle age people?

Btw, Happy Fourth of July.

I’m sorry, but in anything you wrote there, I can’t see an argument against anything I wrote.

No users are expecting updates for free. But users do expect updates to be available for purchase, which they won’t be if the company has made an “successful exit”. Success for the company is a loss for the customers, and a betrayal of the implicit promise of the initial product.

I've made an effort in recent years to actively avoid researching wikis and guides on games as I play them. I've come to think that a lot of the joy in gaming is the discovery and unraveling the systems that make the game tick. Finding the optimal ways to level or complete some mission through exploration and experimentation is always so much more fulfilling than finding the first result the comes up in google where the answer is already there for you.

Admittedly, it does take a degree of willpower and sometimes I will still do some online research when a game gets particularly frustrating. The biggest obstacle to my approach of avoiding online information is that some games feel like they're designed with that in mind and don't provide enough information in the games for an isolated player to really figure everything out.

> Does it do anything to ensure data integrity, like journaling does?

What kind of journaling though? By default ext4 only uses journaling for metadata updates, not data updates (see "ordered" mode in ext4(5)).

So if you have a (e.g.) 1000MB file, and you update 200MB in the middle of it, you can have a situation where the first 100MB is written out and the system dies with the other 100MB vanishing.

With a CoW, if the second 100MB is not written out and the file sync'd, then on system recovery you're back to the original file being completely intact. With ext4 in the default configuration you have a file that has both new-100MB and stale-100MB in the middle of it.

The updating of the file data and the metadata are two separate steps (by default) in ext4:

* https://www.baeldung.com/linux/ext-journal-modes

* https://michael.kjorling.se/blog/2024/ext4-defaulting-to-dat...

* https://fy.blackhats.net.au/blog/2024-08-13-linux-filesystem...

Whereas with a proper CoW (like ZFS), updates are ACID.

I use it at work everyday. I work with people who use it everyday. 100x is complete and utter nonsense.

100x means that I can finish something that would have taken me 10 years in a little over a month.

It would be obvious not because people are posting “I get a 100x productivity boost”, but because show HN would be filled with “look at this database engine I wrote in a month”, and “check out this OS that took me 2 months”.

And people at work would be posting new repos where they completely rewrote entire apps from the ground up to solve annoying tech debt issues.

It would take approximately 6B H100 GPU days to crack every active BTC wallet.

So if you had 10,000 H100s running, it'd only take ~1500 years.

You'd have a high probability to find key in under ~1000 years, though.

Even if I'm off by 3 orders of magnitude, it would take a decade and cost billions, and not make financial sense.

Engineering is tradeoffs.

This one turns out to be politically unacceptable.

But context matters:

+ what is the situation without the bridge?

+ what was the budget?

+ what was the timeline?

+ what land is available?

+ how much disruption to the existing transportation network is acceptable?

+ what were the criteria for selecting a design?

+ etc.

I suppose a lot of people are going to die prematurely instead of getting care. That’s a policy choice. Have a conservation with your Congressional rep about it, if it matters to you.

Do you think you can convince people of reproductive age to have kids in this environment? Or do you think people are going to opt out while the wealthy get wealthier? This will speed the decline of US total fertility rate, out of self preservation in a socioeconomic environment that provides no support to parents and the poor.

Some examples here: https://github.com/WICG/compression-dictionary-transport/blo...

show significant gain of using dictionary over compressed w/o dictionary.

It seems like instead of sites reducing bloat, they will just shift the bloat to your hard-drive. Some of the examples said dictionary of 1MB which doesn't seem big, but could add up if everyone is doing this.

I love how people bring up deflationary spiral as a "peril" while the prerequisite for it is the universal and smashing success of Bitcoin.

The only "problem" Bitcoin poses for economies is for governments to fine-tune their local economies via currency production and related controls. In that sense, we should watch how events unfold in Turkey.

* among major "regular" economies, Turkey has the highest % of people holding crypto (≈20%). Second only to special zones UAE and Singapore (31%, 24%).

* Turkish lira is steadily inflated over the last 30-40 years, well over 10% and recently over 50%.

* Turkey does not have mandate for pricing goods in local currency: you can pay in dollars or euros, along the local lira.

* When you enter Istanbul airport, Every. Single. Gate. is marked with BTCTurk ad, inside and outside - the major crypto exchange in the country.

* Istanbul city market is full of traders who use USDT on Tron.

The experiment of social game "Bitcoin" boils down to this: will the people self-organize the functioning economy with monetary freedom, while the gov loses its grip on it; or will the economy collapse without government's regulation and protective management?

There's no "instead". This story is extremely relevant to the many HNers who run tech companies or make regulatory decisions on their behalf. They need to know that tech regulations are written by executive fiat now, they can't trust that any statutory text means what it says, and many of their competitors are seeking out ways to bribe the Trump regime for regulatory advantages.

I understand that a lot of those people enjoy the polite fiction that partisan controversies in Washington have nothing to do with their jobs. I do too, and I hope that we can get back to a world where it's practical soon. But sticking your head in the sand won't save you.

I do this. One mergerfs mount with an ssd and three hdds made to look like one disk. Mergerfs is set to write to the ssd if it’s not full, and read from the ssd first.

A chron job moves out the oldest files on the ssd once per night to the hdds (via a second mergerfs mount without the ssd) if the ssd is getting full.

I have a fourth hdd that uses snap raid to protect the ssd and other hdds.

Build chain problem, not an ARM one. That said, this is THE WORST problem. Having to recompile all dependencies to a platform target just so your own Makefile will build.

I feel like distros have an obligation to cross compile all packages for x86 and arm in their own build chains. That’s ultimately where this problem lies. You can’t apt install the dependencies you need to make install your thing.

> AIs like to write a lot of code

I vibe coded a greenfield side project last weekend for the first time and I was not prepared for this. It wrote probably 5x more functions than it needed or used, and it absolutely did not trust the type definitions. It added runtime guards for so many random property accesses.

I enjoyed watching it go from taking credit for writing new files and changes, and then slowly forgetting after a few hours that it was the one that wrote it ... repeatedly calling calling it "legacy" code and assuming the intents of the original author.

But yeah, it, Claude (no idea which one), likes to be verbose!

I especially find it funny when it would load the web app in the built-in browser to check its work, and then claiming it found the problem before the page even finishes opening.

I noticed it's really obsessed with using Python tooling... in a typescript/node/npm project.

Overall it was fun and useful, but we've got a long way to go before PMs and non-engineers can write production-quality software from scratch via prompts.

Price is dumping today, i wonder how much of a role this is playing. those coins will be hitting an exchange likely. This has always been the problem with bitcoin.. the implicit assumption is that many coins are lost , but if the early adopters start cashing out, prices will fall fast. Institutional buying and retail is still small relative to the early adopters. There are many people , miners who are quietly siting on huge fortunes.

I believe OP's project is just doing some lightweight "make it executable" bits but the actual JediTerm that it is using for the "terminal" part is, itself, on Swing/AWT https://github.com/JetBrains/jediterm/blob/4cef2840aed5ec1d6...

Although, interestingly, while digging up that link I noticed the JediTermMain that for sure makes it plausibly executable so I dunno if OP's project is actually just "for funzies" or if there's otherwise something added https://github.com/JetBrains/jediterm/blob/4cef2840aed5ec1d6...

The lack of highspeed networking on any small system is completely and totally insane. I have come to hate 2.5gbps for the hard stall it has caused on consumer networking with such a passion that it is difficult to convey. You ship a system with USB5 on the front and your networking offering is 3.5 orders of magnitude slower? What good is the cloud if you have to drink it through a straw?

> When I listen to Bitcoin discussions, one of the advantages people bring up is that there is a limited number of it and you can’t just “print” more.

Which can limit economic growth. When money was based the amount of gold available, there were long periods of economic stagnation because of liquidity issues:

* https://en.wikipedia.org/wiki/Long_Depression

* https://en.wikipedia.org/wiki/Great_Bullion_Famine

The stagnation only ended when new sources of shiny rocks were found (California; New World).

I find it a dumb idea what whether or not people can get credit to start/expand businesses would be dependent of solving math problems. Yes, credit creation can be "too easy" and become a problem, but making it "too hard" (or physically/mathematically impossible) is even more dumb.

If you're effectively always in a stateful monad, Haskell's purity offers nothing. Code doesn't look like equations, things aren't trivially testable and REPLable, you don't get a free time machine, and there's syntactic overhead from things like lifting or writes to deeply nested structures and arrays, since the language doesn't have built-in syntactic support for them.

There's ~$188B in Satoshi era wallets.

While ~$8B is huge news, due to the potential that all ~$188B might be in play, when most investors probably expected it was not prior to this - or at least the probability was low enough to barely factor, it's unlikely to crash BTC.

Further, moving BTC is one thing. Showing signs of liquidation is another.

That much should be able to get liquidated intelligently without moving the market.

I disagree that artists copying styles is theft. Tracing or lifting exact elements without materially modifying them, sure, but studying and translating another artist's style takes effort and intent. I agree with your overall point of wealth distribution but I don't think that excuses the data theft component of GenAI. It would still matter morally and ethically even if the financial aspect of it was solved. It's about consent.

Then, I set about gathering all the existing coverage about TVS, and finding the articles’ authors on Twitter to the best of my ability, and then individually tagging them to blast them for not contacting us. This is an example of social engineering, and something I’ve seen from other red teaming efforts and my own projects, that humans are usually the weakest link in any technological system, and often quite easily fooled.

Yes, that's well known. Orwell on language is an important subject too long to discuss here. His rules, though, are still useful:

i. Never use a metaphor, simile or other figure of speech which you are used to seeing in print.

ii. Never use a long word where a short one will do.

iii. If it is possible to cut a word out, always cut it out.

iv. Never use the passive where you can use the active.

v. Never use a foreign phrase, a scientific word or a jargon word if you can think of an everyday English equivalent.

vi. Break any of these rules sooner than say anything outright barbarous.

(Much of this came from Orwell's work during WWII, when he worked at the British Ministry of Information. Part of his job was translating news into 1000-word vocabulary Basic English for broadcast in the Colonies, mostly India. Hammering political speech down into Basic English requires forcing it into concrete terms, which is an act of political interpretation. That's where Newspeak, in 1984, came from. 1984 is semi-autobiographical, based on his WWII job. See "Orwell, The Lost Writings". One of his managers was called "Big Brother" behind his back.)

It still has 10% to go to surpass its previous peak if measured in euros. Which is kind of the point.

Currency depreciation is usually good for the local stock market, that’s not too surprising.

Since Trump’s inauguration even the STOXX 600 managed to outperform the S&P 500 which is something that almost never happened.
