sorry, that's nonsense, you can trivially deadlock without mutexes with message passing.

edit: and to be clear, I'm quite interested in Pony, static typing, shared nothing threading with message passing, capabilities, per thread GC is very close to my ideal programming language. But the bogus deadlock-freedom claim make me question the other claims.

Yeah, "commodification" is the wrong word here. I'm not sure what the best word would be, but it would be more along the lines of "extraction" or "exploitation".

As in: The last 15 years has been just relentless attempts to bend and twist everything the previous generation has built to extract value instead of creating it.

Something like that.

> why do you think that this must happen on the front-end?

It must happen on both frontend and backend, because it's about their communication with each other. So that includes frontend.

> a) serve an error page, leaving that to the backend (at some point the backend must validate anyway)

> b) serve the regular front-end and react to the invalid state with error messages. there are libraries like zod that should make your job easier.

I mean, that is exactly what makes me so frustrated! Sorry, you are just giving a good example of what I'm complaining about. Both of those solutions are sub-optimal.

Here is how I'd implement that by hand if I would write something like nextjs/django:

1.) The frontend always sends a version in each of it's request (in the payload, the header, wherever)

2.) The backend compares that version against what it is expecting and compatible with. If it detects an outdated/incompatible version then there are two options: it is somehow possible to automatically fix it. For example because the used protocol has some mechanism and the developer uses that (such as default values for missing values) or because the developer has manually provided a migration for old versions.

3.) If it can be fixed, all good. If not, the backend sends a message back, saying that the request cannot be processed because the version is too old. The user can then decide to e.g. save their state elsewhere and reload, or just reload. Or do something completely different.

4.) Bonus: while we are at it, why don't have that fronted send regular requests to backend and ask if the version is still up-to-date (especially if it's the type of user that has their browser tab open forever). That would help to prevent data loss or other problems before they even occur, because the user gets an info and can refresh early.

Why should I implement all of that myself over and over again? Are you guys really thinking that this should not be handled, or at least made very easy, by typical weblibs/frontends such as nextss or django?

If they had actually taught / allowed actual procedures it would have been better for me.

I think they did a great job focusing on the important parts of flying for the missions and such but things like ATC telling you to land on one run way and the visual assists leading to the wrong runway are terrible. My big pet peeve is unrealistic ground ops and rules where it is legal and expected to exit a runway and enter a taxi way you will randomly get dinged for entering a taxiway without permission (at smaller towered and towered fields).

Overall, I think it's still credible, but less credible than before, and heavily depends on your situation.

I run a program for students as a replacement for university, so I'm a bit biased when it comes to this discussion. It's useful to analyze both what a student want out of a degree and how a degree is "consumed" by another party (ex. an employer).

1. University degrees are still the "gold standard" in socially accepted proof-of-education. I think this is mostly due to social momentum. A few years of a "bad batch", ex. due to rampant cheating etc, will not change this. When I talk to other hiring managers, it's a bit of mixed bag. Some sorta understand where the students are coming from, as they also think that a lot of courses etc are arbitrary. Others are more concerned about the ethics of cheating, and the implications on a student's character, rather than the education outcomes ("I can work with inexperience, I can't tolerate lying").

2. If you're planning to pursue a heavily regulated profession, like medicine, you most likely need a degree.

3. As others pointed out, the university criteria now more closely resembles a toll someone must pay to access higher-paying jobs. Ie. it's less about education than gatekeeping. Having it doesn't make you qualified. Not having it disqualifies you in many people's eyes. I think this is partially driving a lot of the cheating. Students sense the disconnect from the university program (and schooling in general) vs real skills. It's just another hoop they have to jump through so they will choose the path of least resistance. For many parents, it's a sort of capstone project for a parenting job well-done. And that adds more to the complexity.

4. How you take advantage of your university experience matters. I wouldn't count on the university for a durable education, ie. actually teaching you things that will make you successful. You need to get that elsewhere (thus the emphasis on work experience). But the social momentum is important, as universities are social centers for young adults, so you may get socially isolated if you don't go. In this case, the value is in the network, not so much the programs etc.

The university experience, despite it's flaws, is still the status quo and definitely the safer "bet". Unless a person have clear understanding of why they shouldn't go, they should probably still go.

No, RTL cultures still have the 10ish percent lefties. The difference is, RTL cultures developed writing styles and hand positions to work with RTL. Whereas LTR cultures treat lefties as an afterthought, so lefties only hear about actual good hand positions and writing styles as adults, after decades of learning what is basically a mirror to right-handed style.

The much longer Bloomberg article is also worth reading for background,

https://www.bloomberg.com/news/articles/2025-07-29/top-doj-a... ("Top DOJ Antitrust Officials Removed Over HPE-Juniper Settlement" (July 29))

> "Senate Democrats alleged the removals were the result of improper political influence and lawmakers are pushing the federal judge overseeing HPE’s acquisition to hold a lengthy review of the antitrust settlement."

> "Roger Alford, the top deputy to the Justice Department’s antitrust chief Gail Slater, and William Rinner, who led the department’s merger enforcement, were dismissed Monday, according to people familiar with the situation."

I am a lecturer, despite having being a very immature teen who left school with practically no qualifications. I was able to go back and fix what I had broken. Therefore, I understand the privilege university provides to those who can afford it or live in wealthy enough countries who provide it for free.

There are useless programmers, most are ok, and some great. This is true of students and lecturers. A job or education provides a platform for a person. What a person does with this opportunity is up to every individual.

I believe the biggest problem here is that the author of the blog was using the ultra-wide-angle lens. I can tell by how the players are "leaning" and how the software is "fixing" the curvature of the photo. 90% sure of it. I always use the "regular" lens, and the pictures are much better.

You can also set styles in the camera settings to fix these problems: incorrect AI white balance and lighting.

ChatGPT's original answer was surprisingly close.

Both humans and LLMs fail to multiply those numbers in their heads.

Some people can multiply them using a special algorithm. Either for mind or for pen and paper. Your example shows that LLM knows some of those tricks and can carry out the task using "pen and paper" (context in this case).

Both humans and LLMs are able to do that multiplication correctly using a calculator.

Tbh this is possible only in software. No matter what you do - epic incompetence, leak user data, doxx users, basically allow their identities to be stolen etc - zero consequences.

Kinda crazy. In any other industry they would not even allow you in the door without showing some king of understanding what you do.

You can't even sell hotdogs without food license. But in software - wild west.

I had been experimenting with some prompts for socratic method of teaching. Finally found one which works fairly well for me which I have integrated into our product.

Q: How does photosynthesis work?

Chat GPT Study Mode:

### How Photosynthesis Works (in simple steps):

Photosynthesis is the process *plants use to make their own food* using sunlight. It mostly happens in *leaves*, especially in a part called the *chloroplast*, which contains a green pigment called *chlorophyll*.

---

### Think of it like a recipe:

1. *Ingredients*:

* **Sunlight** * **Water (H₂O)** — from the roots * **Carbon dioxide (CO₂)** — from the air

2. *Cooking place*: Leaf cells, in their chloroplasts

3. *Magic trick*: Chlorophyll traps sunlight energy

4. *What’s made*:

* **Glucose (C₆H₁₂O₆)** — a sugar the plant uses for energy * **Oxygen (O₂)** — released into the air

---

### Word Equation:

*Carbon dioxide + Water* → (with sunlight & chlorophyll) → *Glucose + Oxygen*

Or:

*6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂*

-------------------------------------------------

My Prompt(conversation):

me: How does photosynthesis work?

agent: Great question! Let's start by understanding the problem. What do you think is the main purpose of photosynthesis in plants?

me: dont know

agent: That's okay! Let’s start by breaking down the concept of photosynthesis. First, can you tell me what kind of organisms primarily use photosynthesis?

me: plants

agent: Exactly, plants primarily use photosynthesis. Now, let's think about the basic ingredients or components needed for photosynthesis to occur. Can you name any of these components?

me: no

agent: No problem! Let’s explore it together. Photosynthesis primarily requires three main components. One of them is light. Can you think of where plants might get light from?

me: sun

agent: That's right! Plants get light from the sun. Sunlight is crucial for photosynthesis. Now, besides sunlight, plants also need something from the air. Do you know what that might be?

Show HN: Testing 3 Filters: Tulip Nebula – Which One Works Best?
by karlperera | 2025-07-30 12:12:16+00:00
Hey HN,

I recently captured the Tulip Nebula using three different filters (Optolong L-Pro, ZWO Duoband, and No Filter) and put together a video comparing the results. The goal was to see which filter brings out the best detail and color in this complex emission nebula.

The video covers comparison of single exposure and stacked images, the differences, and my thoughts on which filter is the best choice depending on your gear and goals.

I’d love to hear your feedback or any tips on narrowband imaging and filter selection you have!

It sounds more like the US IC treats HP like one of its own departments, and it would very much like to do the same with Juniper.

The idea that even allies will be using US networking equipment in a couple decades seems implausible. Everyone is well-aware that any boxes coming out of the US are as likely to be tapped as ones coming out of china.

I dunno, those look quite realistic and even a good thing for a plugin system that needs to run in a sandbox:

- The Windows API is not supported => would be a security nightmare if allowed

- C++ exceptions are not supported => not surprising, game code usually forbids exceptions anyway, along with RTTI

- C++ threads are not supported => really shouldn't be needed in a plugin system,

- The GDI+ wrapper is very incomplete => surprising that they even attempt to wrap GDI+

- The WebAssembly module must be compiled in Debug mode for C/C++ code for symbols to be visible while debugging => need to compile in debug mode in order to debug, doh.

> Most appropriate length for what? Some iPhones have multiple focal lengths, ...

Most appropriate length for portrait photography is well established to be somewhere between 50mm and 100mm (35mm equivalent). The lower end is often considered more "natural" for such photo type, while the longer focal lengths are considered more flattering.

An iPhone 16 Pro Max has three focal lengths, 12, 24 and 120 (35mm equivalent). The first two are much too short unless significantly cropped, and the last one is excessive and requires stepping way back and has the worst image sensor and likely worst compromise of a lens - a lot of lens chonk is elements to manage chromatic aberration and distortion, which smartphone lenses have no room for.

> ... just like some "real camers" have fixed lenses with a fixed focal length (Fuxji x100 and the medium-format one whose model I can't remember, Leica something-or-other, Sony R1).

People using fixed lenses do so because they prioritize a particular type of image or style, and decided to get an even better (and lighter) lens for that instead of carrying around a compromise they don't need.

> Plus, for what is a traditional camera "just better"?

When it comes to getting the best picture, a chonky camera always wins - although they have had some catch-up to do on the software side, physics and our current technical limitations do not care about pocketability.

But a less perfect picture is better than no picture because you left the "real camera" at home. The best camera is the one you have on you.

(Also note that this is not binary between a smarpthone and an Olympic DSLR setup. Good compact cameras with collapsing lenses and mirrorless with smaller lenses are a middleground.)

Yeah I mean at this point, the tech industry is not new, nor is its playbook. At least within B2C, sooner or later everything seems to degenerate into an adtech model. I think it's because the marginal cost of software distribution is so low - you may as well give it away for free all the way up to the 8 billion population cap, and then monetize them once they're hooked, which inevitably seems to mean showing them ads, reselling what you know about them, or both.

What I have seen nobody come even NEAR to talking about is, why would OpenAI not follow this exact same direction? Sooner or later they will.

Things might pan out differently if you're a business - OpenAI already doesn't train its models on enterprise accounts, I imagine enterprise will take a dim view to being shown ads constantly as well, but who knows.

But B2C will be a cesspit. Just like it always ends up a cesspit.

>Should we trust the information at face value without verifying from other sources? Of course not, that's part of the learning process. Will some (most?) people rely on it lazily without using it effectively? Certainly, and this technology won't help or hinder them any more than a good old fashioned textbook.

Not true if we make the assumption that most books from publishing houses with good reputation are verified for errors. Good books maybe dated but they don't contain made up things.

You know that feeling when you spend your weekend creating a lead magnet, launch it, and get... 12 signups?

Yeah. I lived that nightmare for 2 years.

Here's what used to happen:

Friday: "I'll just whip up a quick lead magnet"

Saturday: 6 hours later, still fighting with Canva

Sunday: Writing landing page copy that sounds like robot vomit

Monday: Launching to crickets

Sound familiar?

So I built Majorbeam to end this cycle forever. Here's how it works:

You tell it: "My SaaS users struggle with onboarding"

6 minutes later, you get: A complete lead magnet PDF that actually helps Landing page copy that converts Email capture system ready to deploy Social posts to promote it

No design skills. No copywriting. No templates.

Just plug in the problem and watch it build your entire funnel.

The part that blew my mind: During testing,

Mike (SaaS founder) generated 847 qualified leads in 2 weeks.

Jenny (business coach) went from 2% to 18% conversion rate overnight.

On average, 15 emails of potential leads per campaign.

These aren't edge cases. This is what happens when AI actually understands your customer's pain.

Why this matters: Most founders know they need lead magnets. But creating good ones is a skill that takes years to master.

Majorbeam doesn't just generate content. It analyzes what works, understands your audience, and creates something people actually want.

It's like having a lead gen expert who works for free and never sleeps.

I'm launching this today.

The question: What's stopping you from creating lead magnets right now? Is it time? Skills? Not knowing where to start?

What is amazing is how much the modeling tech has improved. A modern warhammer model is much bigger and better not just than in the 80s or 90s, but even 110 years go. The painting experience is also much better. As for Gundam, the improvements in detail in assembly makes Games Workshop's models look bad and expensive. An amazing attention to the building experience. Even cheap HG model made this year would look like it was from Mars compared to the first few series, and it's still very cheap.

It's not the reason why this conspiracy got started. It got started by a fraudulent pseudoscientific paper with financial ties to it. We shouldn't be reducing human intelligence and ability to process information to the "wet streets cause rain" level. I know it's easier said than done though. When a scientist claims that "highly unlikely that vaccines cause autism", it still leaves the same room for doubt as when they say "it is very likely that vaccines do not cause autism".

The real issue isn't scientific caution. It's that the misinformation campaigns exploit any uncertainty, no matter how small. The solution isn't dumbing down science communication, but being clear about what the evidence actually shows.

> The Israelis expelled a massive number of people into the surrounding countries, and have since refused to allow the Palestinians to return to their homes, which are inside what is now Israel.

A huge part of the Exodus was the Arab league telling Arabs to leave their homes in 1948 while they destroyed the new Jewish state, because they didn’t just want Jordan and the proposed second Arab state from British Palestine they wanted everything from the river to the sea, which probably would’ve destroyed all the jewish people (witness all the violence pre-1948 from Arabs to Jews). Meanwhile, contrary to arab nationalist claims, ben gurion asked Arabs to stay and peacefully join the new country which is why Israel is 20% Arab.

The other thing you’ve omitted is the greater number of Jews that were expelled from Arab states. you haven’t asked for them to be able to return either, but it’s probably not a good idea as they would be killed, as is typical for anybody who doesn’t follow or has left Islam in Arabic countries. Witness the current genocide against the druze people in Syria.

saying my points are a rehash of standard propaganda is silly: anyone can verify that we know UNRWA staff are members of hamas, that UNRWA facilities are routinely used by Hamas, that UNRWA schools teach children to desire to be martyrs and that UNRWA has a different definition of refugee than UNHCR. The very obvious solution is UNRWA should be disbanded.

I believe there is thorough, observable, evidence to suggest that consciousness is manifest exclusively through the brain.

Persons with damaged brains have damaged consciousness. Persons with underdeveloped brains have underdeveloped consciousness. People without functioning brains have no detectable consciousness.

There is a metric ton of observed and collected data on consciousness.

Of course evidence does not equal proof…

> WebAssembly doesn’t include a system interface, i.e., any way to interact with the outside world, so it isn’t an apples-to-apples comparison.

For a plugin system this sort of isolation from the outside world is pretty much a hard requirement. You don't want random plugins to read/write/delete random files in your filesystem.

Well sure, but quite frankly people undervalued my education when I started out in the job market in the beginning of 2020. They undervalued it in terms of the technical skills I've learned simply because they projected their educational experiences onto mine. That's what that it is.

But apparently _now_ it seems we're going to a world where hiring managers don't believe _anyone_ to have those skills, even if they in fact do have it.

I guess new grads have to make a portfolio on the side and take care of the code quality. Because even if you vibe coded that application, vibe coding a project with high code quality still shows a strong skill in programming as LLMs aren't there yet to do that fully themselves?

Like, how are skillful new grads supposed to show their skill when everyone (is about to) believe their education doesn't show any evidence of skill?

And yea, I agree, cheaters will be cheaters. I'm not talking about them, they're a lost cause in my opinion.
