This got me curious about our Exasol environment, which we've been running since 2016 at Piedmont Healthcare. We average 2 million queries per day (DDL/DML/DQL). Our query failure rate is ~0.1%. Only 7% of those failures were due to hitting resource limits. The rest were SQL issues: constraint errors, data type issues, etc. Average connected users is ~400. Average concurrent queries is ~7 with a daily max average of ~78 concurrent queries. Avg query time across DQL statements is around 10 seconds, which is only that high due to some extreme outliers -- I have users that like to put 200k values in a WHERE clause IN statement, and Tableau sometimes likes to write gnarly SQL with LOD calcs and relationship models.

TPC-H benchmarks are what convinced us to purchase Exasol 10 years ago. Still happy with that decision! Congrats to the Exasol team on these results vs ClickHouse.

Very interesting to watch, though I don't really have a great idea of what's going on most of the time. Performance seems to be fairly poor despite my system being pretty beefy (Ryzen 9 7950x3d). I see the performance monitor and notice that the render loop seems to fairly regularly exceed the latency for 60fps, despite this being a 'simple' task by modern standards. I'd give more helpful feedback as to why, but the minified code makes it hard to say.

Do you plan on monetizing this somehow? If not, open sourcing some, if not all, would be pretty cool, even if it weren't necessarily licensed in a way that others could 'take' it, if that's your concern. Nonetheless, a very cool project.

Reminds me of the time they made towns all around the US do a dog and pony show to attract "HQ2" and then just located it where Bezos wanted to be all along. I remember AOC getting it right all along, she did the most milktoast of pushback in her district and it caused Amazon to huff and puff and just walk away(causing many property speculators to lose out). She got raked over the coals but a few years later and the place HQ2 ended up didn't fare so well. AOC was vindicated.

My hope is that more towns learn from your experience and don't tolerate this nonsense anymore.

I never did the collision physics, but I used to love making graphical demos with "falling sand"-type simulations.

One of the first was "rain" [1] by semi-randomly walking blue pixels down the screen and not clearing the buffer. But then the screen would go all blue, so I made them pop up to the top and do the same walk but as black pixels. It came out as a rain-on-the-window effect:

https://x.com/Rendello_/status/1231426590380318729

Eventually, I started just using one pixel and moving it really fast to render scenes. This is basically what raster rending does anyway, but instead of doing every pixel, the random walk will only hit a subset of pixels every frame and will make a really cool scratchy effect.

That’s a complicated question. The Wonderwerk Cave in South Africa where we found the first evidence of controlled fire also contained burned plant remains and bones, which could be interpreted as evidence of cooking. There were also burned fish remains found at the Gesher Benot Ya’aqov site in Israel, dated to about 780 kYA, which could also be interpreted as evidence of cooking.

By far the strongest evidence is the Qesem Cave in Israel, which had a central hearth and so many burned animal remains that it couldn’t have been accidental. Unfortunately the dating on that is controversial and the error bar is huge at 300 +- 100 kYA (200,000-400,000 years ago).

> The painful to answer question is whether the intention is to block the spreading of lies or the spreading of truth?

What it should be about is preventing someone else from blocking the spreading of truth.

"Block the spreading of lies" is something authoritarians say when they want to declare any criticism of themselves to be a lie and censor it. You can't block the spreading of "lies" without ordaining someone as the decider of truth and there is nobody you can trust to have that power.

But if we were actually doing what we should then what we would be doing is developing censorship-resistant uncentralized systems rather than fighting over the keys to the censorship apparatus.

> sometimes use tiktok
> use it regularly

That's not how these words work. A reasonable person wouldn't think these phrases are interchangeable when taking about something addictive -- in this case TicTok. Someone who "smokes sometimes" and someone who "smokes regularly" are very different groups. This isn't an attack; I understand you now, I'm just trying to get you to see where I was coming from.

> Like I already said I ... that I never experienced before.

You had not said that yet, you just said I said you were wrong.

> this was entirely different and coincided in time with the complaints of censorship.

If you think this statement isn't reasonably interpreted as you implying and leaning in to, or in the very least encouraging, this conspiracy theory, then I think you are being disingenuous.

I was trying to provide helpful information by giving someone who only "sometimes" uses tiktok some assurance that these changes are typical.

You can't give all the blame for the deaths to Hamas. They gave Israel a monstrous provocation, but the decision to kill tens of thousands of civilians, and collective punishment by denial of food, water and medical care was the Israeli government's.

If party A is using a human shield, and party B decides to kill the human shield to get revenge on party A, then who is culpable for the death? I don't think it's an entirely obvious answer. I don't think anyone who can easily and automatically put all the blame on party A or B has really thought it through.

>I don't even understand [...]

>It is not different from groceries.

Do you appreciate that, in the wider historical context, this position is an exceptionally radical one? You seem to not understand how there could even exist a difference of opinion on this, but I'm confident that this outlook of humans as being completely fungible, transactional economic units would appear unthinkable to anyone throughout 99% of human history. Just the suggestion that a nation's population should be restocked by swapping it out with another nation's population would be tantamount to treason any time prior to the revolution of the 1960s.

Ideally yes, but there's plenty of cases where that's not desirable or possible.

For example, most people would agree you should use exhaustive checks when possible(matching in rust, records in typescript, etc.). But how do you enforce that? Ban other types of control flow? But even if you find a good balanced way to enforce it, you won't always want to enforce it. There's plenty of good use cases where you explicitly don't want a check to be exhaustive. At which point now you gotta make sure there's an escape mechanism to whatever crackhead check you've setup. Better to just leave a comment with a link to your style guide explaining why this is done. Many experienced developers that are new to rust or typescript simply never think of things like this, so it's worthwhile to document it.

I don't fear mass shootings any more than I fear terrorist perpetrated subway or event bombings.

> you're not going bankrupt because of a minor/medium medical condition

Medical debt and the discourse around it is interesting. Not having insurance is the fundamental issue, medical debt itself is legally mandated to be negotiable. As in they are legally required to find a negotiable payoff price that will work for your personal financial situation, similar to school debt. I pay $70/month for school debt and will for the next 25 years. Is that a lot? Yes. Does it matter to me? Not so much. I could be wrong about the medical debt, but I don't think i am.

Show HN: Watermark – Browser based image/video watermarking with FFmpeg.wasm
by a_void_sky | 2026-01-27 17:34:51+00:00
Hi HN!

I built (vibe coded) a completely browser-based watermarking tool that processes images and videos locally without any server uploads. Link: https://watermark.akatski.com

Everything runs client-side - React + Vite, deployed on Cloudflare Pages. No backend, no file uploads, no tracking (except GA).

Would love feedback on the UX and any performance improvements for video processing!

Built this because existing tools either require uploads (privacy concern) or cost money. Wanted something free that respects privacy.

I'm in South America.

If I doom scroll TikTok without cookies from a residence in South America, I will be presented with anti American propaganda showing videos of recent events or people speaking in Spanish about the atrocities that the United States is committing against Spanish speaking people that is recent.

I'm am describing objectively what I see.

The United States didn't want TikTok controlling what is visible to people in the United States so they banned TikTok. Later the United States offered allowing it to be sold to an American company.

Currently, there are two extremely influential forces for people under 25 years old in Spanish speaking Latin America, TikTok, a Chinese company, and an American music artist, Bad Bunny, who likely is the single most influential person in the Spanish speaking world. Let's stay tuned for the Superbowl.

> talented people having more options is generally good for everyone

While I support free markets, that argument sounds a bit like the basis of the old 'trickle-down economics' and similar theories such as global free trade: Help the wealthy and the benefits will 'trickle down' to everyone else.

It turns out that if you help the wealthy, then the wealthy benefit. I know that doesn't sound like a surprising result when it's said that way, but the point is that the rest is a convenient fiction the wealthy tell themselves and politicians tell the public, in order to serve themselves.

In the US for example, those policies have led to historic increases in wealth for the few, and stagnated wages for the many. On the other hand, in less well off economies such as China and Brazil, the policies led to historic numbers lifted out of poverty - far more than anything in history. So that's a great result that we absolutely should not ignore or put a stop to. I support free trade.

But if the policy isn't specifically designed to benefit workers in the US, for example, if they are left to get theoretical second or third order theoretical benefits, it won't work for them. It's not 'generally good for everyone' unless it's made that way.

a surprising amount of people seem to genuinely believe law enforcement (generally, not just police) is at its core based on discretionary actions guided by their moral values and not a morally neutral action upholding agreed upon contracts

that is to say, the law only applies to you if you do "bad" things. and ill be honest, there is a level of truth to this to me. from a practical standpoint, it is infeasible to formally understand every nuance of every law ever created just to be a citizen. The underlying core social contract does appear to be one of "if you do 'good' things, generally the law will agree with you and if it doesnt then we wont hold it against you the first time"

*the important caveat here is that this leaves a rather disgustingly large and exploitable gap in what is considered good vs bad behavior, with some people having biases that can spin any observable facts into good or bad based on their political agenda. Additionally, personal biases like racism for example, influence this judgement to value judge your actions in superficial ways

> I find it interesting to watch as some of the most well-known software developers at the major AI labs note how their jobs are changing from mostly programming to mostly management of AI agents.

"AI labs"

Can we stop this misleading language. They're doing product development. It's not a "laboratory" doing scientific research. There's no attempt at the scientific method. It's a software firm and these are software developers/project managers.

Which brings me to point 2. These guys are selling AI tooling. Obviously there's a huge desire to dogfood the tooling. Plus, by joining the company, you are buying into the hype and the vision. It would be more surprising if they weren't using their own tools the whole time. If you can't even sell to yourself...

I’m plenty calm. There’s just nothing to debate here: the blog post and repo are a conscious, deliberate, and egregious misrepresentation of fact.

>Israel opposed the war knowing that it would be damaging rather than beneficial

Here's a video of Benjamin Netanyahu doing the opposite of opposing the Iraq war in front of Congress in 2002.

https://www.youtube.com/watch?v=rVPauUOVrmk

>Not only had the war in Iraq hurt Israeli security, rather than improving it

I am aware there was internal debate in Israel on relative benefits of taking out Iraq's conventional military capability, its economic potential, remnants of its WMD program and breaking apart Iraq's territorial integrity versus the risk of Iraq falling under Iran's influence. Evidently Netanyahu's faction prevailed in the debate. Though both sides would have preferred taking out Iran first before going after Iraq.

>what you have is a conspiracy theory.

You can call it whatever you want. The true test of a theory is if it fits the evidence and its ability to predict events. Do you have a better theory of why Americans and Europeans repeat the same failed policies over and over in the middle-east?

Here's my prediction on Iran : I don't know what Trump will do ,if he will ultimately accede to Israel's wishes, but if a 'civil war' breaks out or If Trump or any future American regime decides to invade Iraq. It will conservatively lead to a decade of war, one million deaths, millions of refugees (from Iran, Iraq). If the Islamic Republic collapses I am doubtful on whether Iran will survive as an integral nation. But Israel will get what it wants. which will be - taking out Iran's nuclear program, breaking Iran apart and Israel becoming the regional uncontested power (until Turkey or Egypt emerges but thats the next round). Israel will likely formally annex more of Syria, and Southern Lebanon as well or create a buffer zone rump state. Palestinians will never see sovereignty. They will be ethnically cleansed or live in a glorified bantustan. Iraq may not survive in its current form. It will be a bloody, expensive mess for everybody else. Likely American lives will be lost. I struggle to see how a regime change would be achieved without US boots on the ground. The Iranian people will be all but certainly worse of. Just like the people of Iraq, Syria, Sudan, Somalia, Libya, etc.

"such as yellow fever"

Yellow fever is spread through mosquito bites and polio is spread person-to-person. An imported case of yellow fever is nearly impossible to spread, while an imported case of polio is virtually certain to spread.

Sorry, but it's simply naive to think that in today's global world we would not import polio. It's already happening right now in the US. The only thing stopping the spread is our current high vaccination rate. You'd have to cut travel to zero in both directions to stop it.

I guess there is still remaining trade volume that could be further reduced by sanctions. While it is a tenth of what is typically traded with other countries in the region, I would say it is still 1000 times higher than the trade with North Korea. Having said that, the example shows that cruel dictators can still survive in isolation (particularly if the rest of the world still continues to be split on basic human rights)

This comment completely misunderstands why NYC (and the core of most major cities) is not impressed by a supermarket.

Wegmans is popular because Wegmansnis good. But if you have a local baker, a local grocer, a local deli, and a small grocery store within the same block, all within walking distance of your apartment, you don’t need to deal with the hassles of finding stuff within a massive supermarket.

You get the highest quality products from people who specialize in those products.

Further, when you don’t have to drive 20-30 mins to go to a grocery store but the stores you need are within a 5 min walk, or more likely, right by the subway exit when you’re returning from work, you buy stuff as you need it, rather than stocking up for days.

Thats why Wegmans opened a store in Brooklyn Navy Yards in an area that’s close to no mass transit, because supermarkets are valuable in car centric areas and not as useful in walkable dense neighborhood.

systemd was a problem for early adopters (e.g., Fedora). Distros like Debian joined the party later and, as a result, got things way more stable. I never had any systemd-related problem in Debian, while for Fedora (some years earlier) I had some bugs affecting my ability to work. They all seem to work very fine now. Things took a while to mature, but it just works now.

Do you think it's nature that people are born without it, or nurture that everyone has it and it's squashed by early upbringing, conformity, rules, and "don't do that", schooling, punishments, rushed and disinterested parents?

(I think it's a thing that introducing money changes intrinsic motivation into money-driven motivation and can ruin it. And that might also happen for children for other rewards - praise, sweets, dessert, etc.)

> This is completely bipartisan, both US parties take turns shitting on their two greatest enemies: the Bill of Rights

Ignoring the magnitude to draw a false equivalence is a great way to discredit your position. Neither party is perfect but only one of them is denying the full personhood of over half the population, having armed men threaten the public with lethal violence over constitutionally-protected activities, or saying that the executive should be able to direct private industries for profit. Debates about things like how much the government should ask private companies to enforce their terms of service are valid but it’s like arguing over a hangnail while you’re having a heart attack.

Tolerance uses an LLM to score social media posts by manipulation tactics (rage bait, engagement farming, emotional exploitation) and progressively blurs high-scoring content. The more a post tries to grab your attention, the harder it is to see.

I built it because I'd been fighting a doomscrolling habit for 15 years. Blockers never worked, I'd just override them. Tolerance broke the habit in two weeks. I still reflexively open Twitter and Reddit, but I close them in seconds because there's nothing rewarding there anymore.

I started feeling entitled to my own attention. Manipulation that I used to scroll past now feels like a violation. The less a post tries to grab you, the higher the actual value tends to be.

You don't understand, and your unwillingness to approach this issue with the nuance it deserves will only drive people towards right-wing extremists. These people are not racists! The federal government increased immigration (largely of TFWs and students) by far too much, and that has put an enormous strain on Canada's housing and job market. Canadians are turning against broken immigration policy, which has naturally become associated with its most visible aspect--the recently arrived, unskilled Indian worker. You must understand the negative sentiment is driven by association with bad government policy, not naive racism towards Indians. Of course, none of this is the fault of individual immigrants or TFWs, but they are part of the problem, because they are symptoms of it.

Racism is a serious allegation. Let's not cry wolf when there is a reasonable explanation here.

There is too much hand waving with respect to AI and their possible interactions in the physical world. Dario is definitely guilty of this. While we currently discuss the economics of datacenters and gpu production, understanding very clearly the supply chain constraints, the bottlenecks, and the huge capital expenses representing them, on the other hand we have entirely separate dialogues about AI risks which pretend none of these constraints exist. AI risk in the networked digital realm is a serious concern. However, I don't believe coordinated datacenters filled with autonomous AI pose a near-term physical expansionist threat. While they may be able to further optimize our supply chains, and usher in a similarly exponential growth in robotics -- people would have to hand hold and help instrument that physicality. I strongly believe such growth would be separate and significantly delayed from the LLM based intelligence gains we are currently experiencing and is likely decades away.
