MarioMan··on Today is when the Amazon brain drain sent AWS down the spout
> They didn't seem to appreciate me telling them that they'd asked this question the last time.

Most places will appreciate if you tell them before you work on the problem. That gives them a chance to give you a different problem instead. Likewise, they won't appreciate if you tell them afterwards since it makes it harder for them to judge any semblance of problem solving skill.

> they gave my then-girlfriend an introductory O'Reilly book on Java after she failed their interview.

That's surprising. I've never seen any major tech company provide any sort of feedback, let alone handing you a book, even if it does feel condescending.

MarioMan··on Ask HN: What are you working on? (October 2025)
OpenAI gives an allotment of free daily tokens if you agree to hand over the inputs as training. I’d love a proxy that places the limit just before you exhaust those free tokens, to avoid incurring any expenses for small hobbyist projects.
MarioMan··on I spent the day teaching seniors how to use an iPhone
Here’s the first time setup documentation: https://support.apple.com/en-us/105132

And the general iPhone documentation: https://support.apple.com/guide/iphone/welcome/ios

Sometimes, I wish this documentation was a bit more technical, but it’s not bad at all.

The film on the front of a new iPhone, that you remove to reveal the screen during unboxing, provides pictorial icons of what each button on the phone does. For volume down, you can see a minus in a circle. It’s the bottommost button on the left.

I’m not sure why you had so much trouble creating an Apple ID, but you can still skip that when it prompts you to do so. I believe it’s under “Forgot password or don’t have an account”.

MarioMan··on I spent the day teaching seniors how to use an iPhone
It used to be simpler. I remember it taking years before Apple finally added this ability to move more than one icon at a time, and it’s a change for the better in my opinion. Using it as a reordering technique is a knock-on effect I’d never really thought about, but I think using this to move multiple icons to another page or into a folder makes a lot of sense. I’m not sure how you’d do it better (though I’m sure I’m lacking in UI imagination).
MarioMan··on Don't Become a Scientist (1999)
Those interested in the article may also enjoy reading this one, which really helps to sober your perspective on why one would even go for a CS PhD:

“So long, and thanks for the Ph.D.!” a.k.a. “Everything I wanted to know about C.S. graduate school at the beginning but didn’t learn until later.”

MarioMan··on The Synology End Game
I run TrueNAS Scale at home myself.

There’s no need to proactively check in on anything if you’ve set up email alerts. It’s pretty straightforward to give the NAS permission to send you emails in case a drive dies on you rather than failing silently.

Docker containers are just a nice bonus. You don’t need to use them if you don’t want to, but it is awfully convenient to run things like media encoders, torrent clients, download managers, etc. directly on your storage.

MarioMan··on Unmasking the Privacy Risks of Apple Intelligence
Siri has supported an offline subset of commands since iOS 15 came out in 2021.

I just tested this with Wi-Fi and cellular data disabled. Calling someone works perfectly and asking to turn Wi-Fi on presents the relevant toggle.

MarioMan··on Mastercard deflects blame for NSFW games being taken down
Steam has famously gone on record that they will provide a DRM removal patch for everything they’re legally allowed to, if/when they go under.

If they don’t do this and it’s all just lip service, then it makes a strong argument for ethical piracy at that time.

MarioMan··on Digitising CDs (a.k.a. using your phone as an image scanner)
It’s also stock on iOS, albeit buried in the Files app under More (3 dots in top right)>Scan Documents. It’s especially useful for multi-page documents.
MarioMan··on I hacked my washing machine
We’ve had a few scares. Last year, it didn’t stop filling and caused some flooding across a few rooms before we caught it. Earlier this year, the plastic on the knob mount was so brittle it snapped off. We’ve been servicing it, and we’ll keep it going as long as we can.
MarioMan··on I hacked my washing machine
My washing machine is a "dumb" machine from the '90s. The wash cycles run based on the position of a glorified timer knob: it doesn't have a computer or sensors to detect if it needs extra time aside from the water fill stages. Thanks to this consistency, I just set a 40 minute timer on my phone, and it's always done by then. Can't get much simpler than that. If I need reminders, there's always the alarm snooze function.
MarioMan··on The NFS 4 Freezer Spacer In Science Fiction Sets
One of the more interesting cases of sci-fi greebling is in Infinity Chamber. The film was shot on a budget of only $125,000. Most of the movie happens in a single room. To save money, the backdrop used 2 liter soda crates the filmmakers found discarded at the back of a grocery store. Later they discovered that the crates are regularly reused, so they returned the unintentionally-stolen props after filming.
MarioMan··on Have I Been Pwned 2.0
It's more than just the email. If you're in the breach, it might now publicly tie your email to things like your real name. You also have to worry if you reuse passwords (which you shouldn't do even if you haven't been in a breach), because now the password in the breach is known to be used with that email address, and attackers will pivot to other services to try those same credentials elsewhere.
MarioMan··on Apple violated antitrust ruling, judge finds
Getting there via the App Store is just one option. You can also get there from Settings under Apple Account > Subscriptions.

And if that’s too tricky, you can just type “Subscriptions” (shows up after just typing “sub” for me) into Spotlight Search, and it’s the top option.

MarioMan··on Apple violated antitrust ruling, judge finds
A 25% price jump would cause much grumbling. That being said, I’d like to believe that there’s a real market for bootloader unlocked iPhones.
MarioMan··on I thought I bought a camera, but no DJI sold me a license to use it [video]
In the comments, he mentions that he will be returning the unit as defective.
MarioMan··on The Death of the Web (2024)
The wild thing is that the web has achieved both the aspirations and the failings mentioned here. There's an odd dichotomy of user experiences.

Progress really has accelerated. "Big data" couldn't have been a thing without the Internet. Science through improved communication is advancing more rapidly than ever before. Just look at how quickly things change today vs. 100 years ago in all aspects of life.

Knowledge is everywhere, you just need to know where to dig to work around all of the junk. You no longer need to take up an apprenticeship to understand the basics of a given job, and knowledge as a whole is more accessible than ever before.

We really can communicate with people all over the world. The Internet is always active, because users from across the globe are always online.

The Internet has accelerated globalism. People can readily expose themselves to outside ideas and perspectives, so long as they take the effort to step outside of their algorithm-prescribed interest bubbles every once in a while. You can make friends on the other side of the planet and communicate far easier than you could ever send letters or pay for long-distance phone calls.

People still make their own websites. I'm sure there are more of them then there ever were in the '90s, they're just significantly harder to surface in the deluge of the modern Internet.

Ads, pop-ups, and modals are only experienced by people that don't know about worthwhile ad/nuisance blockers.

Ultimately, the Internet is filled with more content rather than strictly better content than ever before. Though as a consequence of more, it means there's also more great knowledge and more likeminded subcultures available than ever before, but you need a certain kind of discipline to actively work to find it. This is why I feel that information literacy is one of the most important life skills: if you can find the "good stuff", discriminate fact from fiction, and dig deeper than an AI-generated Google summary of search results, then you have the means to learn and develop talents in just about anything.

MarioMan··on Costa Rican supermarket wins trademark battle against Nintendo
I think it's been AI upscaled. Here's another article with more sane looking images of the logo: https://www.eurogamer.net/nintendo-loses-trademark-fight-aga...
MarioMan··on Minecraft with object impermanence
I felt the same way using GPT-2 and AI Dungeon back in the day. The surrealism and incredibly short-term memory was a big part of the fun.
MarioMan··on Ask HN: Is anyone doing anything cool with tiny language models?
There are a couple of WebGPU LLM platforms available that form the building blocks to accomplish this right from the browser, especially since the models are so small.

You do have to worry about WebGPU compatibility in browsers though.

MarioMan··on CRT Simulation in a GPU Shader, Looks Better Than Black Frame Insertion
For the longest time, I thought this was the only limiting factor, but modern panels are low enough latency for it to work, yet still don’t.

The other important factor is the light filter. The NES Zapper has a filter designed to only be sensitive to high-frequency light sources like CRT screens.

>It’s already a thing to have records deleted from the archive which should be the most worse thing when your whole concept is to archive.

IA doesn't delete archives, they merely make them inaccessible. Perhaps that's a distinction without a difference in the near-term, but it means things like copyrighted content will be republished after copyright expires.

MarioMan··on The science of "Zoom fatigue"
I'm a bit miffed that Zoom "outs" you as someone with a webcam. If you have a camera, it shows up as such in the participants list. All of my desktop webcams are virtual, but Zoom couldn't know that. It gives this false notion that I'm rudely keeping my cam off, when really I'm just preventing people from seeing a static OBS virtual camera screen.

On the flip side, if you want to be sneaky, you could probably remove/disable all of your cameras in software, which then telegraphs to everyone that you don't have a camera at all, even if you do.

MarioMan··on The science of "Zoom fatigue"
That's a latency issue, and there's no real fix for that.

The parent commenter, I believe, is talking about the problem where people use speakers and active noise cancellation, which makes it impractical to speak and be heard at the same time; the noise cancellation will ruin the speaker-user's mic audio while it has to cancel out another speaker. Headphones, worn by all parties, resolves this issue.

MarioMan··on NotebookLM's automatically generated podcasts are surprisingly effective
There is limited prompt control. You can provide podcast production notes for the AI to play off of, and they tend to honor it. I don’t know that they’d so completely change their personalities to suit it though.
MarioMan··on Show HN: Instant HTML Preview Bookmarklet
I've wanted to abuse this to support a static site "hosted" entirely from a QR code, but I haven't found any QR scanners that interpret the data URI as something to open in the browser. And without wide support, that project is hardly worth bothering with.
MarioMan··on Radio Shack Catalog Archive (1939-2011)
Last time I was in the bay area, I went to Central Computers, and it fills a lot of the niche that Microcenter offers elsewhere in the country. It's one of the few places I can find Raspberry Pis at MSRP (without the high shipping prices from online retailers), and it has enough worthwhile parts for you to build your own PC if you wanted, too.
MarioMan··on Ryujinx (Nintendo Switch emulator) has been removed from GitHub
I was shocked to learn there was a short period in the '90s when even reselling your physical games was outlawed in Japan. At the time, Nintendo put "no resale" icons on the back of all their games.
MarioMan··on Paperless-ngx: scan, index and archive all your physical documents
Among other things, it usually means that the file type has wide interoperability (which makes it more likely you can open it in the far future) and comes in a format resistant to damage, so if bits are changed or removed, you can still recover the rest of the document (usually this means avoiding compressed formats). As to how well-suited PDF/A is for these aspects, I'm not experienced enough to say.
