jetrink··on James Webb Space Telescope captures high-resolution image of Uranus
You'd be surprised by the dynamic range of the human eye. I happen to have my camera on my desk, so I used it to take a couple measurements just now. It's a bright, sunny day.

Pointed out the window[1]: 1/2000th

The interior of my office[2]: 1/30th

My office feels brightly lit to me, but the ambient light level is only about 1-2% of what it is outdoors. I estimate that 0.25% is roughly how bright it is indoors on an overcast day or outdoors at twilight on a clear day. It's dim, but people with unimpaired vision have no trouble seeing in that light level and the planet would still look spectacular.

1. Grass and trees with no sky in frame.

2. Shades open, light grey walls mostly. Same ISO and aperture.

jetrink··on QMoE: Practical Sub-1-Bit Compression of Trillion-Parameter Models
You can rent such a system for less than $4/hr. That sounds pretty affordable to me!
jetrink··on Dissolves: The out-of-fashion film trick that makes 'The Holdovers' so affecting
They even went to the effort of making the opening titles look like they were not made on a computer. I saw the movie in an old, single screen theater that also uses retro pre-feature announcements and it was such an immersive nostalgic experience that I really wasn't ready for.

jetrink··on Firefox Keeps Getting Faster
Thanks for the suggestion, that looks like a good workaround.
jetrink··on Firefox Keeps Getting Faster
I only have Bitwarden, uBlock Origin, RES and Vue Devtools installed right now.
jetrink··on Firefox Keeps Getting Faster
I'd like to see better stability. My biggest issue with Firefox on Windows right now is that it hangs if I leave it open for several days. Mozilla does have a suggestion on their support site: don't do that[1]:

> Firefox hangs after using it for a long time

> Firefox may hang if left open for long periods of time. To fix the issue, restart Firefox.

So I can choose between closing all of my open tabs at the end of each workday or randomly losing them during the workday. Since having my tabs open when I start work helps me jump back in, I've settled on randomly losing my tabs.

They also suggest using their session restore feature after a hang, but with this type of crash, Firefox is never able to restore your tabs. It also doesn't record the crash report in about:crashes. Overall, not great and it has me thinking of trying Brave.

jetrink··on Making noisy SVGs
I agree and the grain/transparency effect specifically looks like the gradients made using a (physical) airbrush that show up a lot in the Memphis style.

jetrink··on Which Movies Are the Most Polarizing? A Statistical Analysis
I wonder if that was due to how much awkwardness there was in the movie.

* It's a divisive mood. Some people find it relatable and cathartic (and hilarious in the context of comedy), while others find it intolerable to the point that they will leave the room during awkward scenes.

* It's not a common type of humor, especially in mainstream American movies, so people are unlikely to have many other awkward comedies in their viewing history.

* Napoleon Dynamite took it to such a degree that even people who enjoy it in small doses might have become exhausted by it as the film went on. (As far as I can recall, that's how I experienced the film.)

jetrink··on Why is Jepsen written in Clojure?
If you don't need something as low-level as next.jdbc, HugSQL is my preferred library. It lets you write queries in .sql files, and the queries are then loaded as functions. If you want to dynamically generate queries, there are also libraries like HoneySQL.
jetrink··on Advent of Code 2023 is nigh
> As others have said, part 2 of today's was really difficult.

I suspect it was purpose-built to foil ChatGPT. I solved it on my own first and then went back and tried to help GPT4 write a solution. Even after carefully walking it through a strategy, discussing edge cases, and having it outline a solution in pseudocode, it still failed completely to translate our conversation into working code. (It didn't even work for non-tricky input.) It did anticipate the edge cases though, so that's something.

Did anyone have any better luck with ChatGPT? I wonder if LLM-resistant puzzles and generally greater difficulty (at least for the second star) will be a theme this year.

jetrink··on Shein Files for U.S. IPO
Yes, I'm wearing one right now that I know I bought at least 18 months ago. If you wash them in cold water and hang dry them, they will last a long time.
jetrink··on Charging a lithium battery to 80% only?
> The case is always as empty as possible, the pods as full as possible. They spend almost their entire life at 100% as a result of the charging case. Even though I always use them at a max of 1 hour or so at a time.

I wouldn't assume that Apple hasn't thought about this or that your earbuds are telling you the truth about their charge level. I have a Jabra headset that is four years old, and it is smart enough to profile my usage and optimize its charging. In normal use, I wear it during the workday and plug it in every night. In response, it slowly charges up to about 60% by morning, which is more than enough to get through the day. However, when I go on a trip and charge it less frequently, it responds by quickly and fully charging when I do get a chance to plug it in. (I only wish I could tell it when I'm about to leave on a trip, but the battery has lasted four years of almost daily use now, so it's a small price to pay.) If Jabra can do this, Apple can too.

jetrink··on Roc – A fast, friendly, functional language
I really like that 'fast', 'friendly' and 'functional' all link directly to long, substantive explanations of the goals and decisions related to those qualities.
jetrink··on Cats are no match for New York City's rats (2018)
Chicago has an estimated 4000 coyotes living in the urban area. I would occasionally see them in parks and graveyards when I was out walking at dawn, but otherwise they are almost invisible. Rodents, including rats, make up about 75% of a coyote's diet and a single coyote can eat about 1800 per year. They are a welcome predator in the city as they keep a very low profile and keep to themselves, except for the rare instance where they make the news, like when one visited a Quiznos and took a nap in the beverage cooler.

jetrink··on SpaceX Loses Starship Spaceraft During Test Flight
> SpaceX Loses Starship Spaceraft During Test Flight

It's really a glass half empty headline, isn't it? It's like if someone got bronze at the Olympics and the headline were, "Athlete loses to multiple opponents, fails to get gold or silver medal."

jetrink··on Is the reversal curse in LLMs real?
The paper is not talking about information provided in the context, only training and fine-tuning.

> In fairness, it’s also worth pointing out here that they’re making the claim that the reversal curse only applies to training and fine-tuning and not in-context – i.e., putting all your information inside a prompt. They point out in a footnote that you can put A to B data in a prompt and GPT-4 will make B to A connections just fine. Unfortunately, this was lost on many of the people covering the pre-print.

jetrink··on How five researchers fared after leaving academia
It's not a false positive though. The headline is designed to grab your attention by manipulating your curiosity. How did they fare? I prefer that headlines like this are penalized.
jetrink··on Steve Wozniak suffers minor stroke
That's wonderful. Do you happen to remember the true version of the science fair story?
jetrink··on Leaf blowers are a scourge. Why is it hard to get rid of them?
If you spend Saturday morning revving multiple 90dB engines in your front yard, the police will come and ask you to stop... unless you're using them to blow leaves around. Leaf blowers don't need to be banned, we simply need to stop treating them as an exception. It seems to me that the best solution would be to enforce existing noise and pollution ordinances and require landscapers to get quieter (possibly electric) equipment.
jetrink··on Big landlords used software to collude on rent prices, DC lawsuit says
The key difference is this:

> [E]very morning, RealPage provides participating Lessors with recommended price levels. Lessors typically must communicate to a RealPage “Pricing Advisor” that they have “accept[ed]” or “confirm[ed] the “approved pricing” within a specified time frame. If Lessors wish to diverge from the “approved pricing” they must submit reasoning for doing so and await approval.

[...]

> But RealPage emphasizes the need for discipline among participating Lessors and urges them that for its coordinated algorithmic pricing to be the most successful in increasing rents, participating Lessors must adopt RealPage’s pricing at least 80% of the time.

This organization was enforcing 'discipline' among the participants to make sure that they didn't undercut each other too often. That's a cartel.

jetrink··on Penn and Teller's Lab Scam [video] (1990)
According to the copyright at the end, this is from 1990. (Speaking of pranks, I was completely fooled by the poster's username and thought that was a broken timestamp.)
jetrink··on The killer features of the Steam Deck
> is sleep just normal PC suspend-to-RAM? Doesn't that work on normal PCs?

Yes, but it's very well implemented. In fact, it's so quick and dependable that if I'm playing a game and someone comes up to talk to me, I'll put the device to sleep rather than pausing. (Not for any particular reason, it's just muscle memory now.) I've played a dozen or so games of all types so far and have never had a problem with suspend yet, so it seems that Valve did put a lot of effort into it.

jetrink··on YouTube now blocking ad block
My objection to the first argument is that I don't think YouTube adds a lot of value to my life; it's the individual contributors who do. These creators are on YouTube because that's where the audience is and vice versa. I have a lot of problems with Google's stewardship of this dominant position and I don't want to do anything to perpetuate it. The creators who do add significant value to my life I support directly through Patreon and/or through watching them on Nebula, which is a paid video service.
jetrink··on Google owes executive $1M after losing gender bias lawsuit
In the United States, the law says that employers can't discriminate against any individual on the basis of sex. It doesn't matter what the sex of the person is.

jetrink··on Solreader: E-Ink Smart Glasses for Reading
Good points, but I'd quibble about the price being too high for a single use device. There is a segment of the population that spends a lot of time reading and they don't mind spending money for a device that provides a good reading experience. The original Kindle cost $399 back in 2007 and sold out in hours. The high-end Kindle still costs $250.
jetrink··on Friday Factorio Facts #381 – Space Platforms
I love how when asteroids are destroyed, they break apart into smaller asteroids just like in the old arcade game.
jetrink··on Edinburgh couple are handed £17K bill by Tesla as they 'drove in rain'
I live on a road that floods regularly and I'm always amazed by how many drivers are willing to drive into water that is over two feet deep[1]. Car after car, they plunge in like amphibious operation is a standard feature on new vehicles, sending water over the hood and a wake across my front lawn. All that is to say, I would not be surprised if these people forged ahead into deep waters and are playing dumb when it didn't work out.

jetrink··on Do authors get paid for ad placement in novels?
When authors go out of their way to avoid using a brand name, it can be equally distracting though. I'd prefer that a character simply visit YouTube rather than visiting 'an online video site' or some fictional site with a made-up name like Chumhum. I think a distaste for product placement has sensitized us to seeing brand names in fiction, but some brands are a part of our daily lives in a way that is difficult to avoid.
jetrink··on ChatGPT’s system prompts
It's unexpected to me that they repeatedly list recipes alongside lyrics as a special case, since as I understand it, recipes are not copyrightable, at least in the United States. Is this not the case in all countries? On second thought, I wonder if it's for another reason like preventing the system from reproducing inedible or dangerous recipes that people have planted online.
jetrink··on People are happier in a walkable neighborhood: the US community that banned cars
> Buying groceries for a family for whole week

That's the thing: when your grocery store is a short walk away, you don't buy groceries for the whole week. You just duck into the store on the walk home or you walk over at lunch. You buy things for that evening or a few days at most. Having to plan for a whole week of meals seems normal to us, but it's an adaptation to the fact that we live too far from grocery stores. With our large fridges, cabinets, pantries, and chest freezers, we basically turn part of our homes into well-stocked convenience stores so that we can go out as little as possible.
