antirez: I moved two servers, one from Linode and the other from DO to Hetzner a few months ago, with similar savings. The best part was that the two servers had tens of different sites running, implemented in different languages, with obsolete libraries, MySQL and Redis instances.
dabinat: I’m formulating plans to switch from AWS to Hetzner. Amazon gets you by charging high prices (sometimes 20x more than competitors) and forcing you to make long-term commitments in order to get the prices to somewhere more reasonable.
mariopt: Every time I see this kind of article, no one really bothers about sb/server redundancy, load balancers, etc. are we ok with just 1 big server that may fail and bring several services down? You saved a lot of money but you'll spend a lot of time in maintenance and future headache...
adamcharnock: This is something we've[0] done a number of times for customers coming from various cloud providers. In our case we move customers onto a multi-server (sometimes multi-AZ) deployment in Hetzner, using Kubernetes to distribute workloads across servers and provide HA.

What HN said:
andai: For a fair comparison you need to look at the total cost, because 4.7 produces significantly fewer output tokens than 4.6, and seems to cost significantly less on the reasoning side as well. Here is a comparison for 4.5, 4.6 and 4.
hgoel: The bump from 4.6 to 4.7 is not very noticeable to me in improved capabilities so far, but the faster consumption of limits is very noticeable. I hit my 5 hour limit within 2 hours yesterday, initially I was trying the batched mode for a refactor but cancelled after seeing it tak...
glerk: I'd be ok with paying more if results were good, but it seems like Anthropic is going for the Tinder/casino intermittent reinforcement strategy: optimized to keep you spending tokens instead of achieving results.
kalkin: AFAICT this uses a token-counting API so that it counts how many tokens are in the prompt, in two ways, so it's measuring the tokenizer change in isolation. Smarter models also sometimes produce shorter outputs and therefore fewer output tokens. That doesn't mean Opus 4.

visiohex: Kdenlive hits the perfect sweet spot for me. It's much more capable than basic editors like iMovie, but doesn't have the overwhelming learning curve (or steep hardware requirements) of DaVinci Resolve.
Rapzid: A couple years ago I did some basic OBS recording of technical stuff and needed a simple, preferably OSS, editing and compositing solution polish up the vids. The landscape was bonkers. After trying lots of free, freemium, and paid trials I finally landed on Kdenlive.
marginalia_nu: Kdenlive has some unfortunate performance regression when working with larger projects with many clips. I managed to track down a few of them while evaluating Claude Code a while back (mostly certain actions doing O(n) scans over all clips every mouse event needing debouncing), a...
nickjj: I wish Kdenlive had 2 things: 1. A way to play back videos at 2x speed while editing in an intuitive way (DaVinci Resolve does this perfectly). TBH I'm not sure how this isn't a feature since it's straight up a 2x time saver for anyone editing a video since playing back a 10 minu...

What HN said:
vantassell: > Japan is one of the only countries to have privatized parking. In Europe and North America, vast quantities of parking space is socialized: municipalities own the streets and allow people to park on them at low or zero cost.
ttul: “Japan’s liberal land use regulation makes it straightforward to build new neighborhoods next to railway lines, giving commuters easy access to city centers. It also enables the densification of these centers, which means that commuters have more places they want to go.
linzhangrun: The most core reason should be that they built a dense railway network embedded in cities very early on, and developed in a mutually dependent manner; just as the United States, after large-scale highway infrastructure and becoming a pioneer in civil aviation, was destined to bec...
decimalenough: This made it to the HN front page 4 days ago, under its (terrible) previous name "The secrets of the Shinkansen": https://news.ycombinator.com/item?id=47762060 And the top comment was mine, pointing out a bunch of factual mistakes and misleading claims: https://news.ycombinator.

What HN said:
somat: "The second approach was to use a digital computer to determine the solution. This solution was rejected because in 1963, a digital computer was expensive, slow, and less reliable." This inflection point between analog and digital computer is a fascinating one.
Animats: This is from the era of devices where the I/O was entirely electrical but the computation was mechanical. Most of this stuff came from naval gunnery. The naval "fire control tables" started out as mechanical computers where a rather large number of people were inputting different...
po1nt: Everytime I read articles like that, I envy the engineers that worked in development of such tools. First microprocessors in jet fighters, electromechanical celestial navigation... And here I am fighting gitlab pipelines.
pests: Read every word. i liked this detail in the footnotes: > The Astro Compass needed to know approximately where in the sky to find the star, in order to point its sensor in the right direction.

What HN said:
mickdarling: I used it today to take a look at my previously built design system with Logos, branding, fonts, and everything else. After a lot of annoying tweaking back and forth, finally, I got something that was satisfactory.
markbao: I don’t really buy that Claude Design will remove all the complexity around design. Vibe-coded apps using Claude look simpler because they are simpler. They’re not a gigantic product suite with extremely specific UI components tailored to each use case.
alkonaut: So let me get this straight (Pretend I'm 50, a developer since childhood, but I can't CSS to save my life) are there shops where developers, even front end developers, have to talk to designers who are't just sketching an idea for a logo or landing page, but designers who run thi...
allan_s: As someone who spent quite some times these days to reverse the figma protocol[0] I can't agree more with > Figma accidentally excluded themselves from the training data that would have made them relevant in the agentic era.

What HN said:
seanhunter: If you want to learn category theory in a way that is more orthodox, a lot of people recommend Tom Leinster’s Basic Category Theory, which is free[1]. I’m going to be working through it soon, but the bit I’ve skimmed through looks really good if more “mathsy” than things like TF...
gobdovan: If someone does not want to check the mathematics line by line and prefers to give the article the benefit of the doubt, note that it also presents this JavaScript: [1, 3, 2].
dgan: I think it is pretty obvious that at the challenge with all abstract mathematics in general and the category theory in particular isnt the fact that people dont understand what a "linear order" is, but the fact it is so distant from daily routine that it seems completely pointles...
throw567643u8: The author's writing style and overuse of parentheses is excruciating. True parenthetic material is rare, good technical writers use them sparely.

adzm: Everyone talking about magenta and brown, but you can see an illusory color right now even without lasers! https://dynomight.net/colors/ behold, some kind of hyper-turquoise
nabakin: > When it comes to information transfer and processing, light can do things that electricity can’t. Photons — particles of light — are far zippier than electrons at working their way through circuits.
mapt: Is there a single person here interested in photonic computing that wants to explain to the class if there's any "there" there?
SEJeff: The US Navy has been working on their idea of a holy grail they have deemed the free electron laser[1] [1] https://boeing.mediaroom.com/2010-03-18-Boeing-Completes-Pre...

throwatdem12311: When I did my Computer Science degree the vast majority of courses were 50% final, 30% midterm - even programming exams were hand written, proctored by TAs in class or in the gymnasium - assignments/labs/projects were a small part of your grade but if you didn’t do them the likel...
ninjahawk1: In one of my classes the approach was the opposite, I’m expected to do Ph.D level work as an undergrad and am expected to use AI. In a different one she just said so long as you say AI was used you’re fine to use it. In the rest of them AI is considered cheating.
whartung: What's interesting is that as I understand, folks are using things like Google Docs for papers, and that it's (apparently) straight forward to do analysis on a Google Doc to see, well, the life of the document. How it was typed in, how fast, what was pasted and cut back out.
recursivedoubts: I used to make my classes 60-80% project work, 40-80% quizzes all online. I now do 50% project work, 50% in person quizzes, pencil on paper on page of notes. I'm increasingly going to paper-driven workflows as well, becoming an expert with the department printer, printing compute...

JAG_Ecalona: The one detail that always gets me with these charts: penguins who've just been broken up with will refuse to eat. Also apparently one female ended six relationships in a single year, and the staff description of her, translated from Japanese, is something like "basically demonic...
omoikane: I tried to decipher the naming themes: Festivals: - Tsuzumi = drum used in festivals - Taiko = drum used in festivals - Happi = clothes worn in festivals - Wasshoi = shout used in festivals - Hanabi = fireworks - Matsuri = festival - Chouchin = latern...
otras: I would absolutely watch The Real Penguinwives of Sumida, and I bet a lot of other people would too!
cl42: Goodbye Zachary's Karate Club, hello Sumida Penguin Romance Chart!
