Image editing model training is fascinating. One method for training image editing models involves using a second model to apply the inverse of the change you want the model to learn. Typically, the task you’re asking the second model to perform is easy, whereas the inverse task is difficult.

For example, you might ask the second model to cover the person’s face with a black square; a VLM model notes that the person is a man with brown hair and round glasses. Then, during training, the resulting image is presented along with the prompt, “Remove the black square from the man’s face. He has brown hair and round glasses.”

The model now learns how to remove black squares and replace them with a man’s face with brown hair and round glasses.

Since the training data is easily synthesized using existing models, you can generate enormous amounts of it - often very cheaply. For specialized editing tasks, this technique is really powerful. Build your training set for your special purpose task, fine tune an existing image editing model such as Qwen Image Edit to produce a new checkpoint or LoRA (often a LoRA is more than good enough) and then you have a special purpose model to perform whatever narrow editing task you need it to perform on your image data.

Stop drinking. If you can consistently stop after one, you can do that, but zero is way easier than one. Bad hangovers are brain damage. Don’t ever do one again.

The most important relationships in your life are the ones where you’re naturally your best self. Prioritize those. My best relationships are the ones where I’m a good friend to them. You might be thinking of it backwards. (I sometimes have made that mistake). A betrayal of a good friend will haunt you forever. Think carefully about how to be true to those most important to you.

Save for down payment and buy a house. That’s the path to generational wealth.

Spend less than you make.

Create a habit of daily exercise. This becomes increasingly important in later years.

Everyone should work for a big successful company at least once (I used to say FAANG, but obviously with the renames that’s not true and also the world has changed. Start by making your list of the most important companies in the world). Learn as much as possible from the smartest people possible (also keep track of what NOT to do and how not to behave). Don’t stay so long it eats your soul.

This is godawful, I hate it. If you aren't physically disabled or injured you have no business using this kind of thing. I do not want to live in the world where otherwise fully-capable human beings are not even using their own legs to walk anymore either because they can't be bothered to get off the couch for an hour a day or because they don't have the time to improve their health.

Absolutely disgusting nonsense. Get off my lawn, robot hippies

> Managing code is one of the cornerstones of software engineering. It would be like refusing to learn how to use a screwdriver because someone really just wants to hammer things together.

Ok, then make the commands make sense. For example 90%+ people has no idea what rebase does, yet it is a useful command.

People does not want to learn with git outside of what works, because they can't experiment. The moment they will "hold it wrong" whole repo will break into pieces, unable to go forward or backwards. Hopefully they did not commit.

Git feels like a hammer covered in razor blades. The moment you will try to hold it differently you will cut yourself and somebody else will need to stich you up.

Keep in touch regularly with your friends and acquaintances after you no longer are in the same school or company. When 25, it feels like you will know and remember them forever, and vice-versa.

I'm here to tell you that you won't, unless you make an effort.

(Of course, I remember the guy who was in a group I ate lunch with in grad school who ended up running Google 25 years later; I don't know if he remembers me...)

“But just to be sure, I got in touch with a friend of mine who works at a research reactor, and asked him what he thought would happen to you if you tried to swim in their radiation containment pool.

“In our reactor?” He thought about it for a moment. “You’d die pretty quickly, before reaching the water, from gunshot wounds.”

This definitely solves a good problem. Company don’t keep generally good confluence docs and documentation. Somehow if there is common source of truth it helps to entire org in a company.

The fundamental way how youtube content is organised is channels. You find a few channels you like, you watch their back catalogue and you subscribe to their new content.

And it is indeed a business layer too. The people making the channel gets paid for their trouble per views. Each channel is a little brand with their own idea of what kind of content they will give to the viewers and in what shape and what kind of quality.

I’m sure what you describe is different from this in some way, but it is weird reading that you wish youtube had channels without mentioning that it already has them.

> because I lost so much time finding great content sometimes that it’s sad.

Idk if you are pickier than me, or have even more niche tastes than I do, because in my experience youtube is full of great content.
by cft | 2025-10-26 17:24:11+00:00
Means for example, that this video https://www.youtube.com/watch?v=AnR4Xw74_is had only <0.1% of YouTube algorithmic views (like 7 total), all the rest were "direct" link. All other videos in the same channel had >70% of the algorithmic views (YouTube "suggestions" or "related content").

They did not ban it outright, so you cannot complain or rigorously prove their bias, but they algorithmically suppress dissenting content.
Show HN: The Dead Sea Scrolls Visualized
by dandeto | 2025-10-26 17:24:24+00:00
The Dead Sea Scrolls is one of the greatest archaeological discoveries in recent history, and its relevance is bolstered since it is of interest to Judaism, Christianity, and Islam. I had heard of the discovery as a kid, but was surprised to realize how little I knew about it once I started reading books and watching videos by Hebrew Bible scholars on the topic.

I made deadseainsights.com to explore the discovery in an interactive and visually-engaging way. I was also very interested in the differences between the Dead Sea Scroll texts, which are dated to 250 BC - 150 AD, and the Masoretic text (specifically the Leningrad Codex), which is dated to around 1008 AD.

To do this, I could not use information from the books I read, since the text and translations are under copyright. I was able to find permissively-licensed transcriptions of the Dead Sea Scrolls and the Leningrad Codex, for which I am grateful. You can find more information about that on the homepage.

Since HN is probably interested in my tech-stack: I kept it simple and built a static website that uses Bootstrap and D3. It’s hosted on AWS S3 and distributed to 108 edge locations via AWS CloudFront. So far, hosting has been under the free-tier limits and has cost me nothing.

Thank you for any feedback you’d like to give.

If you read the LKML thread with Linus' rant, you would know that big endian ARM* is a problematic part of the Linux kernel that the maintainers are removing due to lack of testing let alone receiving bug fixes. It's also implied that big endian causes problems elsewhere beyond ARM, but no examples are given.

Later on in the thread, Linus states that he has no problem with historically Big Endian architectures, it's just that nothing new should be added for absolutely no reason.

*ARMv3+ is bi endian, but only for data, all instructions are little endian.

There absolutely was a real-world non-research operating system called just "BSD", and it ran primarily on DEC VAX hardware to start. Other Unixes like SunOS eventually started basing themselves on it. The last official Berkeley Software Distribution was 4.4BSD-Lite in 1994, which by then had been ported to many other platforms, including i386. The Computer Systems Research Group which maintained BSD disbanded the next year.

Could you clarify? As far as I can tell, GND is A1/B1 and A12/B12, VBUS is A4/B4 and A9/B9, D+ is A6/B6, and D− is A7/B7, and each A pin swaps with its B counterpart when I flip the connector.

> It doesn't solve the problem- its the end of the day when solar has ramped down that the crises happens. Its the duck curve. Where its still hot and air conditioning is still running hard.

Isn't that scenario a problem only when the output from solar is insufficient to meet the aggregate demand?

From a naive point of view, it looks like this issue would be easily mitigated if supply from solar was increased enough to allow energy to be stored during peak hours so that it could be introduced back in the grid during sunset. Why is this scenario being ignored in a thread on how California is investing in battery energy storage?

My rough guess is that they set a few workflows combining analytical and ML-based image manipulations to generate the training set. For instance, you can get a long way by having a segmentation model identify and mask various objects and then apply simple analytical manipulations to the masked areas such as changing their color, or diffusing new content into that area using masked guidance to another image diffusion model. In this way, you can create training pairs that your editing model learns to invert, such as “turn the woman’s hair into blonde hair” (start with a blonde haired woman, mask the hair, and get a diffusion model to turn it brown; this gives you the scene you can now invert as a training pair).

Had we bothered with Modula-2, released in 1978, where Niklaus Wirth took care to fix all ISO Pascal issues from 1976, we would not have such problems.

Also he has a pretty much dual approach to his criticism, while having Pascal dialects is a flaw, apparently having C dialects is a plus.

Clojure is practically just as interactive, I don't feel that difference will be note worthy.

I will say, all the warts in Clojure will be due to the constraints of the Java host and some of it leaking through. In that sense, Common Lisp has a better runtime that's really dedicated to itself and works in full harmony with the language. You get nicer compact binaries that run on a lower footprint.

But the flip side, is the Java host allows you to have access to everything you'd ever want, in terms of libraries, and you get access to things like virtual threads, native compilation, etc.

I believe the tooling in Clojure is more modern, there are now more polished plugins for all Editors, nice debuggers and so on. Not necessarily more features, just more modern feel.

The other big difference will be that Clojure is heavily functional and has few imperative constructs. No local mutable variables, no mutable loops, no standard global mutable variables, not object oriented, etc.

Show HN: I made a brutalist closer-to-retro directory for new product launches
by drex91on | 2025-10-26 17:28:19+00:00
i built Launchy with the help of an open source base as a small experiment in bringing back the feel and vibe of old-school web directories, but with a focus on new product launches.

the goal was to see if directories could feel more human and less like a modern simplistic vibe everyone seems to be going for these days.

you can browse launches, submit your own, or just enjoy the aesthetic.

i'm curious what you think, does the minimalist and brutalist throwback design still appeal to today's builders, or are the modern clean and simplistic approaches better?

You say this as if you discovered some major flaw. And is, of course, expected that also some vaccinated people die from COVID. The point is that the risk of dying substantially decreased with vaccination. Something one can only find out by doing a scientific study. And that this risk decreases was confirmed many times in many studies by many independent scientists. For example, here is a recent meta-review summarizing results from 33 studies: https://publications.ersnet.org/content/errev/34/175/240222....

Of course, I am very sure you will also find some flaw or inconsistency in this or in all of the 33 studies that you take as proof as why this is all "ultimately" wrong. But at some point you need to ask yourself: Are basically all scientists that look into this professionally incompetent or correct? Or maybe, just maybe, it is me who got worked up a little bit in a conspiracy theory and not every flaw or inconsistency is clear proof that I am right and science is wrong.

Well, look, here is my use case. I have some really old hardware that I used to play with earlier in life, it’s located at the parents’ place. I still use that hardware, but not too often, since I live on my own. I could replace all that, as it consumes a lot of power indeed (comparing to SBCs). But in absolute numbers, they’re just regular computers, so power draw is somewhere at 60–90 Watt/hr, I suppose. Which is not that much, especially given I run the machines half a day once a month. What I learned over the years, you can utilise some servers by not running them 24/7. One server there, I wake it over LAN nightly, copy some backups there, and turn it off again. Very useful. So, I think I’d keep them running for as long as they’re alive.

That's not an excuse.

A sample from the website's About page:

> this site is my attempt at creating something that’s dedicated to discovering the hidden gems of the online realm (whether they be in the form of academic discourse, cutting-edge technology, cultural commentary, or artistic expression) and sharing them with care and consideration.

How is treating a country in the second largest continent in the world - which contains more than 50 countries, most of which have very distinct cultures - as representative of that continent showing care and consideration? Ghana is not an unfamiliar country, and most people, at the very least, know it's in Africa. If I confused Mexico with Canada, or Germany with Albania, I'd be treated as a dimwit, but somehow it's totally fine if I don't know the difference between Ghana and Kenya.

I agree with the parent comment; this "unfamiliar country" business needs to stop.

> Even the silly confusing ones have a long life. E.g. "Rule against perpetuities"

That wouldn't be my go-to example of a silly law. It's what prevents control of property from remaining permanently with the will of a dead person who managed to own the property outright. It says that, at some point, the will can have no more influence and full ownership vests in someone who's alive.

Yes.

“Nearly 75 players are active in the CAISO battery storage ecosystem. Top players include EIG Management Company, NextEra Energy, Arevon Energy, Hectate Energy, and Cultivate Power, all of which have eight or more projects underway” [1].

As a man at 25, start to think seriously about settling down with someone if you want a family. Men and women exist on different timelines. While you may think "Oh I'll wait until 30-35 for that stuff", you'll look around at that point and realize you've missed the boat. Of course plenty of people still get married and have kids at that age. But the vast majority of women are either married, engaged, or in long term relationships heading toward marriage by 30, and you won't realize that until it's too late.

I have to admit I don't actually use those yet - I've been enjoying learning how to succinctly prompt in a way that gets the right results without them.

I've experimented with having LLMs write snippets for them - things like "Based on this session, update AGENTS.md with notes about running the tests" - but my stuff tends to be simple enough that I can just say "Run tests with pytest" and it will know what to do.

I did just confirm that you can use efficiently both AGENTS.md and CLAUDE.md in the same repo by having a CLAUDE.md with a single line:

@AGENTS.md

Driving home last night, CarPlay is active, and I have navigation on, and it's driving me home.

I need a snack. Press the button on my steering wheel. "Get directions to Panera Bread."

I fondly remember times when at one company CTO was doing round the dev section at 4:50pm and saying everyone close their machines. Go home or to pub, it's an order.

Once I sent an email at 5:45pm as I forgot to say something earlier about the project. I didn't get a response and in the morning got told off that I should never send an email outside of working hours, unless it is a personal matter that cannot wait.

Couple of years later the owners exited and new management replaced everyone with workers from consultancy of theirs. Company no longer exists.

I don't think a game changes anything.

You can fully reload everything in Clojure as well.

The only limitation is an existing object instance cannot hook into the reload cycle and upgrade itself at runtime. You need to re-create the instance.

But since Clojure is not object oriented, and if you have such objects they'll be from Java interrop, it's not something that you feel you'll be missing or need.

Yes you can hot patch Clojure in production, but modern deployment practices make that not really something people do, as you run multiple instances anyways, it's easier to swap full instances and be sure everything is in-sync with your repo and CI/CD environments.

What people do is more they use a production REPL to help root cause and debug.

From a grid perspective, the output (delivery) is typically more important than total capacity - because it's acting sort of like a power plant.

Power plants don't have capacity, really.

So you hear about the output GW, not the capacity GWh.

For battery plants, they might mention duration (4 - 6 hours), which makes converting to capacity in terms of GWh trivial.

> What distinguishes a terrorist attack from a counter-offensive?

Objectives. Targeting military infrastructure and symbols of a regime can deplete martial capacity and domestic support. Targeting civilians pretty much always results in unifying the enemy—this goes back to Hitler trying to bomb Britain into submission from afar.

> that didn't start on October 7th, so if that's the case, why isn't Palestine getting everything they want

Huh? Nobody argued that everything except terrorism is a winning strategy.

> why aren't you arguing that Israel shouldn't expect to get anything out of their terrorist attacks against Palestine?

They’re the stronger military. Absent international law or pressure, might makes right.

> Last one is a rhetorical question

Literally answered it. If you’re saying you’ve presumed an answer and don’t wish to hear others, sure.

> Israel and the US have all the power therefore their actions are righteous and any sort of retribution is terrorism

You’re getting lost in your own analogies.

We can construct convincing moral models that indict both sides of this conflict because multiple actors have behaved abhorrently. (One or two have more capability and thus can act on their impulses more fully.) If you’re writing as a historian, sure, apportion blame.

If you’re thinking as a strategist, however, outcomes are what matter. And on an outcome basis, October 7 was strategically stupid (it could has been genius, but Hamas and PJ have no discipline), while the current ceasefire saves lives.
