ardme··on A misalignment of AI in mathematics
It's really tough to come to terms with it but making academic contributions in general from the outside (with or without AI tbh) is not often welcome and the whole process feels very gate-kept.
ardme··on Show HN: PureJsImage, image codecs and scientific raster I/O in TypeScript
Hi HN, I started PureJsImage because JavaScript image processing often means using a native addon, a large WebAssembly payload, a browser-only API, or a full source-sized RGBA bitmap. I wanted a portable TypeScript implementation that works in Node.js, browsers, workers, and serverless functions with zero runtime dependencies by default.

Right now the project has many more decoders than encoders. It includes first-party image codecs, TIFF and BigTIFF, scientific raster readers, whole-slide access, and geospatial support for GeoTIFF, COG, and GeoZarr. The encoder side is still much smaller, so feedback on which output formats matter most would be useful.

The main goals are portability, performance, bounded memory use, and reducing supply-chain risk in controlled or tightly reviewed environments. Optional JPEG and PNG WebAssembly accelerators exist, but they are separate explicit imports and are never loaded by the default package.

Some runnable demos:

- Browser viewer and converter: https://purejsimage.com/demo/ - Scientific raster explorer: https://purejsimage.com/scientific/ - OME-Zarr viewer: https://purejsimage.com/ome-zarr/ - Aperio whole-slide viewer: https://purejsimage.com/wsi/ - COG and GeoZarr range demo: https://purejsimage.com/geo/

One of the more interesting constraints has been memory use. Common baseline JPEG resize paths use bounded MCU rows, remote TIFF and COG access reads selected ranges and regions, and the scientific APIs keep native numeric samples separate from display pixels. Some codecs and format subsets still require explicit full-frame fallbacks, and I try to document those boundaries instead of hiding them.

The project is still young, and I would really value feedback on the API, missing formats, decoder and encoder priorities, adversarial files, browser workflows, and useful performance or memory benchmarks.

ardme··on I’m joining OpenAI
Yes I understand what an idiom is jfc. OpenAI was never the enterprise focused company to start and besides they can walk and chew gum. There’s another idiom for you.
ardme··on I’m joining OpenAI
This take is imo very contrarian. Is Anthropic really popping champagne? They kind of look like the bad guys in this entire saga. If not the bad guys the enemy of fun and open source builders.
ardme··on ICE and Palantir: US agents using health data to hunt illegal immigrants
Great question. I thought that only citizens could access public healthcare benefits.
ardme··on ICE and Palantir: US agents using health data to hunt illegal immigrants
I have read the Obama era numbers are inflated because they counted turn aways at the border.

It’s also a little interesting that Obama was able to be against illegal immigration without a ton of pushback. Why was that?

ardme··on ICE and Palantir: US agents using health data to hunt illegal immigrants
It’s not just a simple case it’s an extremely contentious issue the country is deeply divided on based on location and political leanings.
ardme··on ICE and Palantir: US agents using health data to hunt illegal immigrants
I remember a lot of stuff Bush did in the aftermath of 911 that was illegal. Anyone remember Snowden? And Obama did a drone strike on a US citizen. This has been going on a long time but maybe we used to play pretend better.

Isnt the math of buying Nvidia stock with what you pay for all the hardware and then just paying $20 a month for codex with the annual returns better?

Maybe better written and simplified to: “microservices suck”.

who are you to say how people should use energy? This is a pure nihilistic coal post and I think you should think about being less judgmental, it will make you happier.
ardme··on Squarespace to Go Private in $6.9B All-Cash Transaction with Permira
private is not the same as private equity which typically means an external manager is extracting as much from the business as they can. Its often at the expense of longer term growth too.
ardme··on Richest Americans Now Pay Less Tax Than Working Class in Historical First
He didn't though. He paid billions of dollars and she paid a few thousand.
ardme··on Richest Americans Now Pay Less Tax Than Working Class in Historical First
Its because it's false and misleading. What is "more", the wealthy are paying more in terms of dollar amounts. We have very high marginal tax rates in America, and we have very rich people paying a lot of taxes.

In percentage terms the middle class is overtaxed the most of course. But percentage terms are an extremely misleading way to look at this.

Being middle class I'm more angry that the bottom 50% on net pay no income taxes and I'm a net payer into their lifestyle.

ardme··on Celebrity Flights
Paying taxes absolutely increases CO2 consumption because you are enabling the US military to conduct wasteful operations around the world.

We should pay less taxes because the government is extremely wasteful and polluting overall.

Yet obviously, some people find it useful. Who are you to tell people how to live their lives?

Maybe you should stop flying on airplanes for the rest of your life?

ardme··on What is really going on at Amazon Fresh?
The author wrote a book about how AI is all fake and its a bubble so consider the source. I don't think you could get further from the truth right now. Basically the analysis here is 1/10 level.

ardme··on Abuse and Harassment on the Blockchain
It's a question of whether or not you believe freedom of speech is worth the risk somebody somewhere will say something you don't like. At one point people seemed to believe this worth the risk and freedom of speech was good. Now, little by little people are attacking this. Choose safety over freedom and you will be giving your freedom to someone you have no control over, but now they have the freedom to control you.

Yeah uptown got hit really hard. Maybe the other commenters don't live in uptown but I do and the crime issues are pretty wild since the riots. My neighbor was carjacked at gunpoint by a group of teenagers in our parking lot. You have to be very aware of your surroundings now. I'd say about half of the businesses have closed permanently around me.

The Walgreens on 27th and Hennepin gets robbed at least once a month. One time they just shot up drive through windows and the employees left while they robbed the place. Luckily the glass is bulletproof on them. The cops don't seem to really respond things.

One of the weirdest things was this summer where they were doing construction on 28th and Hennepin and there was a cop posted up there during the day. I asked him why and he said "because the construction workers were being assaulted and their tools were being stolen". And this is in a nice area right by Lake of the Isles.

Deny it if you want, it's just like a political mess now because the DA will no longer bring a lot of prosecutions to trial it seems like.

ardme··on Does QE Cause Wealth Inequality?
> It worked out during the Great Depression because all of our rival powers were completely destroyed by WWII. We won't be so lucky this time. China is poised to overtake the US as the top superpower if our economy collapses. In a couple decades, this might not be the case, as they will be facing severe demographic problems.

Pretty much, yep

ardme··on Does QE Cause Wealth Inequality?
Well isn't the issue here that The Fed enables the reckless behavior of congress by sterilizing the deficits?

Yes the root cause is the politicians spending tons of money to get re-elected and running up deficits but they shouldn't be able to get away with it and keep kicking the can down the road.

To your last point - of course it's obvious that interest rates are suppressed and if they were allowed to rise it would cause a depression. But if they were not there would be less mal-investment and the zombie companies propped up by debt would soon collapse. It's not that this wouldn't cause pain in the short term but that you can't just eliminate reality and it's going to happen sooner or later. The longer you delay the worse the ultimate recession might be.

Isn't that what OP did though? Do you see that is hypocritical? I was just parroting back his hypocrisy.
ardme··on Senate approves $250B bill to boost tech research
Thanks, that's interesting to note. The main thing people seem to talk about is the 52 billion for semiconductors which is the "CHIPS" act. Just wondering about the other 200 billion. It looked like $29 billion went to the NSF?
ardme··on Senate approves $250B bill to boost tech research
What exactly is in this bill and where is the money going? I'm having a very hard time researching this for some reason. Is there anything of interest to software technologists in there?
ardme··on Coinbase from YC to DPO
Proof of stake is not secure, there is no way to recover from a 51% attack. Proof of work and proof of space are much better.
ardme··on My app scaled to 46,000 users two weeks after launch and made $0
Super frustrating to see this situation, but in reality I think this happens a lot. Some things are just hard to monetize other than slapping ads everywhere, and if you do that it destroys your product.
ardme··on Ask HN: I have $450K cash, what should I do to maximize my return?
Personally I would put half in foreign stocks (like EFA etf) and half in gold. The dollar is dropping against foreign currencies and they are all dropping against gold. Every central bank is printing money like there is no tomorrow: with good reason we are in the midst of a deflationary shock.

But couple the money printing with record low interest rates (and negative interest rates), this creates a special situation where gold (and other hard currency like bitcoin) outperforms. With a negative real rate on bonds, you will lose inflation adjusted purchasing power in bonds even if you come out positive. There are not a lot of great options right now.
