superjan··on America.gov
I think the discussion ought to be about the site. If you feel the site itself is politicized, that would fair criticism. But by itself, your comment is just snarky. And no I am no fan of the current administration.
superjan··on Grok 4.7
What I notice about Claudish is that it has its preferred cliche’s and overstretched methaphores, it packs too many ideas in a sentence, and to achieve the latter it makes up adjectives.

I should try adding these tips to my system prompt. Is there a shorthand to describe such language use? I am not a native English speaker.

superjan··on I spent $220 on Google app ads and 60% of the installs were robots
The farm also runs the website that gets paid for ads. Google notices that the site triggers a conversion, so they will get the same ad again… It might be more involved but this is a large part of it.
superjan··on iPhone Duo
The phone shows a date of April 1 in several screenshots. I would guess that is to pretend that the images were for an april fools joke in case they leaked?
superjan··on Mushroom hunting with LLMs: what can go wrong?
The false chanterelle that I know is not poisonous.
superjan··on Creepy Crawlies
How feasible would it be to only offer a binary git (partial) download and move the html rendering to the client? It would still be a lot of requests, but less work for those servers. Not that I like SPA’s, but they could be useful here.
superjan··on Stop eating Lady Gaga's Oreos
What also changed is bands don’t sell records any more. You got to pay the bills somehow.
superjan··on When Genius Fails: The Intellectual Arrogance of the AI Labs
Careful what you wish for…
superjan··on Ruby 4.0 Universal RCE Deserialization Gadget Chain
You only need one dev with the bright idea to pass data around via a clientside blob or cookie.
superjan··on Windows 11's built-in Weather app wastes more than 1 GB of RAM
I don’t know if this is sarcastic. A lot of bloat in GUI apps is because they are built as websites with a bloated front end, dependencies, custom fonts plus the binary compiled code and the decompressed images cached by the browser.
superjan··on AI-Generated Images Discourage Me from Reading Your Blog
When I was working on a post recently, I rediscovered that it is actually fun to draw. Much more fun than debating with an AI tool to generate an image for me. And given the time I already spent on the subject matter, the effort was not that much more. I can recommend drawing on paper. You can correct mistakes after scanning.
superjan··on The Dark Night of Mathematics
Not a mathematician, but I suppose there is pressure to publish like everywhere else in academia. And a publication generally requires a new contribution.
superjan··on Someone Used AI to Write an Unauthorized Biography of Me
It tells you that human attention can be gamed.
superjan··on Australian energy retailers must provide three hours of free daytime electricity
You do pay taxes.
superjan··on Your code is fast – if you're lucky
In order of priority, I’d say:

1. If you write CRUD apps, make sure that the database does the heavy lifting.

2. Take note of algorithm complexities, use hashtables as appropriate, and write good hash functions when you start using hashtables/dictionaries.

3. Avoid pointer-heavy datastructures. In high level languages like Java, an object reference is a pointer dereference that can stall the CPU waiting for memory. This is sometimes optimized, but you can’t depend on it. The true zealots call this “data oriented design”.

4. If you write C/C++,rust, or the like, you might want to learn to read assembly. Godbolt.com is a fun way to learn. Note that not all instructions are equally fast: Long division and trigonomic functions are slower than integer adds, even when they are both a single instruction.

5. The next level is probably going for vectorized instructions: SIMD (ARM Neon, AVX). The most original applications can be found at lemire.me: a professor exploring optimizing things like JSON parsing using the latest processor features.

I can imagine it is not the same everywhere. I guess I have an active local chapter of editors. Given that I have 2 comments disagreeing and none concurring I guess this is an exception.
superjan··on Organic Maps
They can’t do so automatically. Osm Editors must approve. Apparantly OSM fears legislation when people copy info from google maps. They like to see evidence, like street sign photos. In my limited experience anyway.
superjan··on IBM debuts sub-1 nanometer chip technology
You can’t make smaller chips features with photonics. Visible light photons have a wavelength between 400 and 800 nm, much larger than current chip features. When you go to higher frequencies they get smaller, but they are really difficult to produce and control.

superjan··on window.showDirectoryPicker opens up a whole new world
Is the camera roll excluded? I bet I am not the only one who has a passport picture in there. I don’t know about other people’s camera rolls, but I bet it is occasionally more saucy than mine.

(Sorry for not testing. Chrome-hater)

superjan··on 15-minute at-home Lyme disease tick test
I’m not sure we are talking about the same virus, but for the version prevalent in northern europe, there’s a vaccine.
superjan··on A 1969 camera operators' strike created Upstairs Downstairs multiverse
That is effectively what Uber did. Internet and GPS make taxi companies and “Knowledge” unneeded for taxi drivers. This destroyed local (badly run) monopolies, but also job security for taxi drivers.
superjan··on How many of the 170k English words do you know?
What I also noticed: when there are two contradictory definitions to choose from, it is usually one of those two.

For all its shortcomings, this was part of the fun, deducing the likely correct answer when you see a word for the first time.

superjan··on Spotify killed the thrill of the hunt
It did not work that way for me. My music interest has been rekindled since Spotify.

You can also hunt via Spotify. Songs and artists can help you find curated playlists (by other artists or fans) where you discover new artists.

Everynoise.com is also a great start, but these playlists are no longer maintained.

There is also a huge audience of people who want to hear “elevator music” tuned to their activity at hand and do not care about who or what made it. Spotify obviously wants those customers. I don’t mind these people subsidising my hobby, but I hope Spotify will continue to cater to my interest too.

superjan··on The intracies of modern camera lens repair (2024)
When telling a story through film, changing what depth is in focus is a great way to move the viewer’s attention, without the need for cutting to a different angle or camera movement.
superjan··on A Gentle Introduction to Lattice-Based Cryptography [pdf]
A nice (short!) video on this topic is this one from Chalk Talk: https://youtu.be/QDdOoYdb748?is=vCFGroHUPwZP7Dqm
superjan··on Voxel Space (2017)
Off topic: The very first assignment in this game is called “oil tank holiday”: fly the chopper to unguarded oil tanks, shoot and watch them burn, and then fly home. No enemies. Just learn to fly and shoot.

I apply this in testing code. After you write some code, try to think of the absolute minimal test to prove that your code does anything at all without crashing. These are my “oil tank holiday” tests. It is always humbling to see those fail.

superjan··on Converting an Integer to a Decimal String in Under Two Nanoseconds
You know, if can change code without overhead to ends of the pipeline, using the language & library of my choice, I’d do this too. For many of us this isn’t always the case.
