>You can rent a VPS from hundreds of possible companies. And people are very happy with them, it seems every month or two there’s a post here about how some company slashed their cloud bill by switching to a VPS.

Companies are using higher-level "PaaS" suite of services from AWS such as DynamoDB, RedShift, etc and not just the lower-level "IaaS" such as basic EC2 instances or pure containers. Same "lock-in" situation with using the higher-level services from MS Azure and Google Cloud.

For those dependent on high-level services, migrating to a VPS like Hetzner or self-hosting is not possible unless they re-invent the AWS stack by installing/babysitting a bunch of open-source software. It's going to be a lot more involved than just installing a PostgreSQL db instance on a VPS.

I'm not sure if this is directly related, but I've noticed my Apple Music app has stopped working (getting connection error messages). Didn't realize the data for Music was also hosted on AWS, unless this is entirely unrelated? I've restarted my phone and rebooted the app to no avail, so I'm assuming this is the culprit.

Doubtful:

1: Methane leaves the atmosphere a lot faster than Co2

2: The methane is a result of breaking down food where the carbon was captured from the air by the plants that were the source of the food.

3: (And I'll let you figure out the numbers) You need to calculate the methane to Co2 ratio of the expected release of methane vs Co2. I suspect there is significantly less methane released than (equivalent) Co2 from cars.

That being said, who wants to go back to horses? I don't.

From the great Corey Quinn

Ah yes, the great AWS us-east-1 outage.

Half the internet’s on fire, engineers haven’t slept in 18 hours, and every self-styled “resilience thought leader” is already posting:

“This is why you need multi-cloud, powered by our patented observability synergy platform™.”

Shut up, Greg.

Your SaaS product doesn’t fix DNS, you're simply adding another dashboard to watch the world burn in higher definition.

If your first reaction to a widespread outage is “time to drive engagement,” you're working in tragedy tourism. Bet your kids are super proud.

Meanwhile, the real heroes are the SREs duct-taping Route 53 with pure caffeine and spite.

Probably caffeine. You might have looked this up and found that cold brew generally has more caffeine than these other types of coffee (although, "traditional" is awfully vague). Keep in mind, different drinks have different levels of caffeine, especially if you're making them yourself. For example, you could be drinking particularly strong or particularly large "traditionally" brewed coffee/espresso relative to the other options.
Ask HN: How Do You Hire?
by lazaruslong | 2025-10-20 18:51:46+00:00
I'm a new founder. Like really new. Dunno if you could call me a founder. anyway, I was thinking of hiring a couple interns. But how do you actually do it? Good thing is that I'm a senior at my uni, so its pretty easy to broadcast it to fellow students. But its pretty hard to actually evaluate whether they can infact build. It makes the job a whole lot worse when you(me) aren't a very good programmer. Sure, I can code. Built a few projects in the my first couple years. But all of my recent projects were sorta vibe coded. I understand what I'm building but that's obviously not the metric. Simply put, I need to hire someone far more skilled than myself. I am confident that I can convey the task without any ambiguity, and can clarify whatever might come up. Past experience, leetcode ratings, even side projects are proxies in some sense to whether they can understand and finish the task. The fact that I never actually took an engineering interview makes it worse, I don't know how its done.

TL;DR: How to interview for an engineering role when you need them to be more competent than you.

I will admit to some bias here. I have been renting now for 22 years and have never had anything beyond a minor problem with a landlord that couldn't be resolved by a phone call. This seems to be the case for 90% of people I know. Then there's that person that is always having problems with landlords / neighbors and I tend to think the problem isn't actually the landlord / neighbors.

> why you think that a 35000 km long cable falling in the ocean from space would cause any less damage to the planet than it falling down on solid ground

They’re not obviously wrong.

A lot of the cable is moving at escape and orbital velocities. Tensile strength is all that holds it together.

If, as the cable fails, you sever the parts above from below around escape velocity, you’ll significantly reduce the length of cable that will ever hit the surface.

It's not really about performance. Imagine comparing AirDrop to a SAN on the basis both provide file sharing functionality. The topic wouldn't be performance, it'd be how they have entirely different use case goals that just happen to both end up using file sharing as one part in achieving that goal.

In the case of ESXi it's about the clustering, filesystem/network virtualization, management and orchestration for hundreds of servers, disaster recovery, enterprise security/software integrations, and so on. That VirtualBox requires a client OS is just a footnote in the comparison of functionality.

Weird anecdote, but one of the reasons I have always struggled with writing is precisely that my process seems highly nonlinear. I start with a disjoint mind map of ideas I want to get out, often just single words, and need to somehow cohere that into text, which often happens out-of-order. The original notes are often completely unordered diffusion-like scrawling, the difference being I have less idea what final the positions of the words were going to be when I wrote them.

The 2000s / early 2010s US is definitely leaving behind some big shoes to fill, no doubt about that. I'm not going to pretend it won't be a painful transition - Europe has been relying on the US far too much since the Second World War.

On the other hand, 2025 US has a president who seems to flips sides in the Ukraine conflict every other week. Considering that the main threat in Europe right now is Russia, that significantly reduces the value of US intelligence. Who needs enemies when your "friends" are just as likely to help you as they are to feed you misinformation?

Interesting to see if this incentive is sufficient to convince those with less than two children to get to two. €2820/year seems...insufficient to move the needle.

The most interesting parts of this to me are somewhat buried:

- Claude Code has been added to iOS

- Claude Code on the Web allows for seamless switching to Claude Code CLI

- They have open sourced an OS-native sandboxing system which limits file system and network access _without_ needing containers

However, I find the emphasis on limiting the outbound network access somewhat puzzling because the allowlists invariably include domains like gist.github.com and dozens of others which act effectively as public CMS’es and would still permit exfiltration with just a bit of extra effort.

"Most" supersonic aircraft are fighter jets and other military aircraft that use jet engines, not rockets. They may have afterburners that are much like a rocket that just injects jet fuel in the exhaust stream, but that's still using atmospheric oxygen.

The issue, I think, is more about balancing drag and air intake at appropriate atmospheric densities for different speeds. An SR-71 Blackbird could fly at 85,000 feet continuously, and a MiG-25 set what I believe is still the air-breathing record max altitude by pulling a "zoom climb" (accelerating in higher-density air that the engines could use effectively, then pulling the stick back and coasting up through rarefied air too thin for the engines) to 38km or 123,000 feet.

Most experimental hypersonic aircraft use rockets because that's what works.

> because there is no guarantee that what one persons gets the same what anybody else gets, so any kind of chance to even discover a compromise is lost.

This applies to "curl | bash", "download an exe and run it", and everything in between equally. If a malicious binary wants to cover up its tracks it can just delete itself and disappear just like "curl | bash" would.

Feel free to educate users about the importance of installing software from trusted repositories whenever possible but demonizing "curl | bash" like it's somehow uniquely terrible is just silly and misses the point completely.

Quitting coffee was a really bad experience for me.

I had what felt like withdrawal symptoms: a strong headache, muscle aches, and I was really cold. It lasted for two days, until I took a minuscule sip and everything went away within five minutes.

That made me realize the extent to which I was actually addicted, and how dependent my body was on it.

I managed to quit and stayed caffeine-free for about a year.

But one day I said, “Just one cup won’t hurt,” and oh boy... it was like having superpowers. I was so focused, so wide awake. Of course, I’m an addict again. :(

I think they are the same, Observable or Observer pattern both require a manual subscription, and publishing is done through a callback offering the latest in a stream of values.

See https://github.com/tc39/proposal-signals?tab=readme-ov-file#... for more on how signals differ. Mainly no manual bookkeeping and the signal is kind of like a handle, and it allows lazy/computed signals that reference other signals and do the change tracking

You can frame anything as being good for you if you search for reasons and ignore any downsides:

- "Coffee reduces risk of developing Parkinson's"

- "Wine helps reduce heart disease"

- "Nicotine stimulates cognitive function"

Like many other drugs, caffeine has some upsides, but also some pretty significant downsides (its dependency-forming properties being one of the big ones).

And since this is HN, adding new dependencies to your life seems analogous to code: Introducing new dependencies to your repo should be done thoughtfully and carefully. Sometimes the pros outweigh the cons (the dependency does something that would save you a ton of work), but there are usually downsides to taking on dependencies as well (increased security liability, relinquished control over part of your stack, more build complexity, slower builds, etc)

https://github.com/HowProgrammingWorks/UUID/ My programming teacher has created his own LLM-assisted UUID implementation to achieve a balance between the time to generate and the bit depth. If I understand correctly this ID implementation consumes the least time per 1 bit of entropy among all JS implementations. It is known that the technical task was three times longer than the code and the code has been generated with just one attempt. The teacher has not modified the output.

You likely used a us-east-1 IAM endpoint instead of a regionalized one ( https://aws.amazon.com/blogs/security/how-to-use-regional-aw... ). We've been using it, and we're not experiencing any issues whatsoever in us-east-2.

One thing that AWS should do is provide an easier way to detect these hidden dependencies. You can do that with CloudTrail if you know how to do it (filter operations by region and check that none are in us-east-1), but a more explicit service would be nice.

Basically when you cut thrust you must pass through that altitude again or escape orbit.

So either fire a rocket in space to circularize the orbit or reach more than Earth’s escape velocity 25,020 mph (11.186 km/s, 40,270 km/h) ~ Mach 32.6, due to some drag in air to thin for any kind of air breathing engine to work.

X-30 was aiming far lower ~Mach 20. Nuclear could make it more realistic than any form of chemical combustion. It might be physically possible using Hydrogen but you’re talking generating extreme thrust at vastly more extreme conditions than the space shuttle’s retry.

I have been self hosting a matrix setup for a few years now, using the spantaleev ansible playbook. It does require updates roughly once a year to keep up with changes of the 3rd party chat APIs. Generally that involves logging into the server and running 'just update' followed by 'just install-all', but occasionally there are changes that need updates to the playbook as described in the release notes. In the worst case, if one of your bridges does go down you can always fall back to the vendor client for that protocol until you get the bridge updated.

Overall it has been absolutely rock solid, and the new element x app has been night and day compared to the old one.

Feels a lot like the days of using Pidgin chat, but since the bridges run on the server you only need to authenticate once instead of going through the process for every device.

Show HN: NativeBlend – Text to fully editable 3D Models that don't suck
by addy999 | 2025-10-20 18:57:22+00:00
I'm a developer (not a 3D artist) who's been frustrated with current AI text-to-3D tools — most produce messy, monolithic meshes that are unusable without hours of cleanup.

So I built NativeBlend, a side project aimed at generating editable 3D assets that actually fit into a real workflow.

Key features:

- Semantic Part Segmentation: Outputs separate, meaningful components (e.g., wheels, doors), not just a single mesh blob.

- Native Blender Output: Generates clean, structured .blend files with proper hierarchies, editable PBR materials, and decent UVs — no FBX/GLB cleanup required.

The goal is to give devs a usable starting point for game assets without the usual AI slop. I have a working demo and would love feedback: Does this solve a real need, or am I just scratching my own itch?

Thanks for taking a look!

Talk about coffee is always skewed between I have no issues and a single drop after lunch ruins my night.

Caffeines half life in the body is strongly tied to age. As you get older, the half life gets so long you cannot metabolize a normal dose in 24hours. That is why people over a certain age often drink decaf.

So just because you can drink 5 cups a day at 25 doesn't mean it's the same at 65, or even 35.

Theanine is calming. For example, pure theanine and magnesium are the only two substances Huberman recommends as sleep aids.

There is a minor complication in which if the brain is in a very stimulated state, then theanine can add to the stimulation, but that has happened to me only once in hundreds of times of my using theanine at bed time, and is extremely unlikely to recur now that I know about the complication.

Also, coffee does not contain any theanine.

Not really a big fan, because the formalization of DS always left something desired, but I think a big difference with formalization in ULC is that ULC is (mostly) materialist while DS is structuralist.

So the initial formalization into ULC can be automated - if you have semantics of your language already implemented as an interpreter in another language, you can use this as a starting point.

With DS - I am not sure. I feel most people who build new languages don't provide DS specification.

Like many here, the annual "language" issue of Byte Magazine in 1980 introduced me to Forth. Although I was enrolled as an engineer in college, I was a frustrated (mediocre) programmer but my upstate NY institute did not offer a Comp Sci degree at that time. Forth was a gateway drug for me and demystified the concept of compiling for me. Prior to Forth, when a thousand Freshman engineers were writing their Fortran IV projects for an 8am class the next morning on mainframe 3270 terminals, we imagined that the operators must have to continuously pour water on the compiler to keep it cool. Yeah, it was 1980 and computers were still a little magic.

But Forth and threaded code was a life changer; it explained so much! My 3rd year, I partially implemented a 32-bit Forth in IBM S360 Assembler but getting I/O to work was my downfall (mostly due to my poor skills and lack of experience.) But the threaded interpreter and the basic stack ops all worked. But then I was introduced to Lisp...

But my love of Forth never left me. I make my living with C in the early days, but predominantly SQL and Bash these days. When I had my second (third?) midlife crisis, I got two tattoos on my arm: one is the Y Combinator in Lisp (I 'lost' a trailing parenthesis due to a cut-n-paste error in the template given to the tattoo artist, so I had to go back and get another tattoo with an error message pointing out the missing parenthesis.), the second tattoo is the implementation of an ANSI Forth word:

: ? @ . ;

The fact that I could write an entire function with only punctuation characters was mind-blowing and reminds me to approach problems in unique ways. The tattoos are also great ways to start up conversations in bars...

The article raises several interesting points, but I find its claim that Claude Code relies primarily on grep for code search unconvincing. It's clear that Claude Code can parse and reason about code structure, employing techniques far beyond simple regex matching. Since this assumption underpins much of the article's argument, it makes me question the overall reliability of its conclusions a bit.

Or am I completely misunderstanding how Claude Code works?

Regarding the flagged/dead comment that links to concern about Daniel Naroditsky's health a few days ago, I don't think burrying our heads in the sand is correct approach now.

It might have been wise to respect his privacy and not talk about him publicly and while he was alive and could read it, but now that posting it cannot affect his mental health, perhaps mental health awareness is important to talk about.

(A side note, I still think the privacy of those who pass away is important, but I think talking about mental health is also important.)

With enough lines, enough brightness, and a high-enough refresh rate, it may become possible have a display that can artificially emulate the features of a CRT -- including phosphor persistence and blooming and focus issues and power supply sag and everything else, with interlacing. AFAICT, we aren't there yet.

If/when this happens, we may be able to again view things as close as they were in broadcast, but with a modern display instead of an an old CRT.

If we can find any content to play that way, anyhow. A lot of it is cheerfully being ruined.

Aside from the dozens of us who are interested in that, most of the rest of the folks seems convinced that television looked just as terrible as a blurry SLP VHS tape does after being played through a $12 composite-to-USB frame grabber, using a 3.5mm "aux cable" jammed in between the RCA jacks of the VCR and the converter, and ultimately delivered by an awful 360p30 codec on YouTube, before being scaled in the blurriest way possible...and draw from this the conclusion that there's no details that have any value worth preserving.

Even though television was never actually like that. It had limits, but things could be quite a lot better than that awful mess I just described.

(For those here who don't know: Towards the end of the run, the quality of a good broadcast with a good receiver would often be in the same ballpark as the composite output of a DVD player is today (but with zero data compression artifacts instead of >0), including the presentation of 50 or 60 independent display updates per second.)

Thanks for sharing these tips — especially the mention of PlasticScore and independent lab testing. I’m working on a project that helps people make smarter financial and lifestyle decisions, and I’ve noticed how small choices (like packaging or product sourcing) can have long-term health and cost impacts.

Curious: have you come across any tools that combine environmental impact with financial planning? I’m exploring ways to make calculators more holistic — factoring in not just money, but sustainability too.
