Way off topic but you just reminded me of all the time I spent playing Warlords 3 (not Warlords Battlecry 3, the original Warlords games were turn-based). One cool feature it had that I'm surprised I haven't really seen other turn-based games do is a "play by email" option similar to correspondence chess, except you're just emailing save files back and forth and the game makes importing/exporting the save files via email a bit more streamlined.
Working for an open-data project, I am starting to believe that the AI companies are basically criminal enterprises. If I did this kind of thing to them they would call the cops and say I am a criminal for breaking TOS and doing a DDOS, therefore they are likely to be criminal organizations and their CEOs should be in Alcatraz.

"The Dark Knight" (Batman, 2009) is the one with the phone-based - is it wifi backscatter imaging - and the societal concerns.

FWIU there are contractor-grade imaging capabilities and there are military-grade see through walls and earth capabilities that law enforcement also have but there challenges with due process.

At the right time of day, with the right ambient temperature, it's possible to see the studs in the walls with consumer IR but only at a distance.

Also, FWIU it's possible to find plastic in the ground - i.e. banned mines - with thermal imaging at certain times of day.

Could there be a transceiver on a post in the truck at the road, with other flying drones to measure backscatter and/or transceiver emissions?

I love _Heat_, EXCEPT for the ending. (Spoilers) It just feels too forced as "the good guy has to win". So, I always stop it when the good guy cop says "He's gone!". It's much more in character with the bad guy; basically his entire career up to that point was being conservative and playing the long time, and I just didn't see the motivation for him to go after the cop and reverse his core policies. IMHO, it's a much better movie that way.

Yeah sounds like a lack of ‘virtual scrolling’. Behind these scenes, they are often creating a tremendous number of markdown renderer components, which are expensive and not meant to have hundreds of instances on a page. It’s a tricky problem imo, and involves tradeoffs with the scrollbar ergonomics.

You can only estimate job you’ve done before.

Everything else is just guessing.

Software engineering is not uniform: agencies working on similar projects may have good estimates.

R&D and novel approaches - usually takes whatever time it needs and then some more.
Yep, I also thought that the article is less about personal projects. The list of software development aspects that the author gives includes CI/CD, good documentation, and integration tests — I'd be surprised if a lot of hobby projects out there had these (apart from what's available out of the box for free, e.g. Vercel's automatic deployment from GitHub).

In the boring professional setting though, I can totally relate. The really hard questions I have to answer at work are usually not about code.

For a one-off script or a weekend project, on the other hand, even the current gen AI is a life-changing thing.
The weird thing is their own data does not reflect this at all. The number of articles accessed by users, spiders and bots alike has not moved significantly over the last few years. Why these strange wordings like "65 percent of the resource-consuming traffic"? Is there non-resource consuming traffic? Is this just another fundraising marketing drive? Wikimedia has been know to be less than truthful wrt their funding needs and spent.

Over the years through my own involvement in sports and physically demaning jobs with trying a lot of different supplementation, I've come to the conclusion that most (if not all) supplements provide little to no value beyond a good diet. If they do, they're either illigal as non-perscription and/or require regular physician monitoring use correctly.

I also had to do a double-take at the blatant falsity of this statement. Software estimation is only hard when it's the first time you're doing it. Unfortunately, most software is a first-time.

There are very few specialty shops which only do the same type of project over and over. This is probably also because such repetitive work would quickly be turned into a "framework" to do more of such work, leaving only the novel stuff for each project, which would then become difficult again.

In the real world, I guess that matches up with the "prefab" type of construction.

Actually:

but I suppose equally (or more?) applicable now.
This sort of study is important, given how highly taken creatine is. I will highlight a part that I think may be especially relevant:

> “The people taking the creatine supplement saw changes before they even started exercising, which leads us to believe that it wasn’t actual real muscle growth, but potentially fluid retention,” Dr Hagstrom said.

I think this is well-known, right? People take creatine specifically because it increases water retention in muscles, making them look slightly bigger. I'm not sure if many people think it will help build muscles and strength directly in the way "TRT" does, but maybe I'm wrong!

My understanding of the conventional wisdom:

- Caffeine and other uppers work from a motivational perspective during workouts
- "TRT" provides massive gains, and nasty side effects
- Creatine makes your muscles look slightly bigger
- Nothing else works

The way I understood it creatine by itself doesn't promote muscle gain all that much. It's the fact that you can potentially do one to three more reps which does. But that still means you have to do the reps.

There are a few different approaches. The main categories, from simplest to most complex:

1) Read replicas with copied data. The most straightforward, allowing using the same SQL syntax and tooling. Examples: Postgres read replica and BemiDB (disclaimer: I'm a contributor)

2) Operational databases with integrations. Designed for sub-second real-time, bring their own extended SQL syntax for things like window functions. Examples: Materialize and RisingWave

3) Analytical databases with syncing. Allow writing and reading directly, optimized for analytical workloads. Examples: ClickHouse and DuckDB

4) Data warehouses with ETL. Great for large volumes of data, traditionally used with ETL batch processing. Examples: Snowflake and Redshift
I've been lifting five to six days a week since 2012, with some de-loading periods between, and have had my nutrition and sleep locked in for the majority of that time. Anecdotal of course, but I will still sit here and say that creatine is the only supplement that has actually worked over all those years - in fact, it's the only one I currently take.

I recover so much better when on roughly 5mg of Creatine for an extended period of time versus when I am not taking any. I also very clearly notice added water weight. That recovery leads to better training sessions which in turn leads to increased muscle and strength.

The difference in water retention and recovery is measurable whether doing a PPL or something like Tactical Barbell blocks.. call me crazy.

EDIT: 5g not 5mg
I've had the pleasure of working with a personal trainer who has a broad educational training background. She emphasized that creatine "kind of helped" but it was really only that last mile 5% benefit. And the effect would mostly be long-term (1-2 years of dedicated training). She just told me to focus on trying to get 1 gram of high quality protein daily for pound of body weight.

This study is just one study, but to me just highlights her same observation even more.
Dupe of https://news.ycombinator.com/item?id=43556443
My take is (and I somwhat agree with the article on this) that if you know requirements, interfaces and tasks precisely enough to give a reliable estimate, then that means that the majority of actual development was already done.

But thats just not the point where people typically want estimates, they want them much earlier.

>The US group, led by Elon Musk, delivered 336,681 cars in the first quarter, far fewer than the 390,000 forecast by analysts and the 387,000 it delivered in the same period last year.

That's a 13% decline in sales. They delivered 3740 cars per day (assuming 90 days in quarter), instead of the 4300/day they delivered last year or the 4333/day they forecast.

I don’t understand the trend of individual studies making it to the top of HN, while metaanalyses are ignored, despite examining 10s or 100s of such individual studies in aggregate to reduce noise.

There are we-are-human reasons, but are there any logical reasons?
Elektrec is Fred's blog and he went from the biggest tesla fanboi to Tesla critic the day that Elon told him to knock it off. It is in general poor opinion blogging masquerading as a news website.
While the dump may be simpler to consume, building it isn't simpler.

The generic web crawler works (more or less) everywhere. The Wikipedia dump solution works on Wikipedia dumps.

Also mind: This is tied in with search engines and other places, where the AI bot follows links from search results etc. thus they'd need the extra logic to detect a Wikipedia link, then find the matching article in the dump, and then add the original link back as reference for the source.

Also in one article on that I read about spikes around death from people etc. in that scenario they want the latest version of the article, not a day old dump.

So yeah, I guess they used the simple straight forward way and didn't care much about consequences.
I wonder if there is a WAF that has an exponential backoff and constant decay for delay. Something like start a 10us and decay 1us/s.

Cool! That's an interesting approach putting the actions in wasm. I'm going for something more tightly integrated into an application rather than entirely in the database layer.

The actions in my prototype are just TS functions (actually Effects https://effect.website/ but same idea) that can arbitrarily read and write to the client local database. This does put some restrictions on the app -- it has to define all mutations inside of actions and capture any non-deterministic things other than database access (random number, time, network calls, etc) as part of the arguments. Beyond that what an app does inside of the actions can be entirely arbitrary.

I think that hits the sweet spot between flexibility, simplicity, and consistency. The action functions can always handle divergence in whatever way makes sense for the application. Clients will always converge to the same semantically valid state because state is always advanced by business logic, not patches.

Patches are recorded but only for application to the server's database state and for checking divergence from expected results when replaying incoming actions on a client. It should create very little load on the backend server because it does not need to execute action functions, it can just apply patches with the confidence that the clients have resolved any conflicts in a way that makes the most sense.

It's fun and interesting stuff to work on! I'll have to take a closer look at SQLSync for some inspiration.
A late reply, but thats not how AWS IAM (or most advanced authz systems) work. AWS IAM is a “capability” system with dynamic policies; its nothing so simple as a “role” based authorization contrary to some product naming. To wit, every authz evaluation is a dynamic evaluation of policy and context. Each check uses one or more policies with one or more policy statements that are combined with some boolean logic and predicate rules. The policies may be associated (sourced) with the particular request based on calling principal, principal attributes, the target resource, a related resource, or even other metadata like AWS Org membership. Thats combined with the point in time context from the request (ex action name, parameters), request metadata (eg time), principal (id, tags, etc), resource (arn, attributes, tags), and some more “system” specific context variables. You (and the authorizing service) need ALL of that information to perform an authz evaluation.

This is complicated by dynamic data, like time or source address or caller principal tag values, so even identical requests may have different results. There are also complications like DENY statements and “unless” predicates that entirely defeat a simple “resource x requires y” approach.

Evem if you solve all of those challenges via magic you end up back at information disclosure where your adversary is now capable of rapidly enumerating and testing all your authz policies!

Where does the genome, genetic representation, you are evolving come from? The same raw features you use in neural networks? Then you optimize using that? If so, why not use gradient descent, which is faster? And this is still a step behind neural networks even apart from the optimization method, because neural networks use composition to learn features. How are you doing that?

Do you have any real world examples of your method that are competitive with DL methods?
could also be "4" or 4! 4 seems like it would be the most evil option, honestly
Yeah. The more the years go by the more the oracle writers of the show are proved right. Frightening
It also helps with short term energy so maximum performance over a 30-90 second window increases, which fits many sports. It’s less useful for endurance athletes or 1 rep max.

“By taking a creatine supplement, such as creatine monohydrate, you can change the amount of phosphocreatine and creatine in your muscles. The extra creatine can help your muscles make more ATP faster as you use it to fuel your cells during high-intensity exercise.

One reason your body builds more lean muscle tissue when you take creatine is that your muscles will hold more water. The pressure from the water in your cells causes your muscles to swell. This water and swelling can also make cells grow.” https://www.webmd.com/vitamins-and-supplements/creatine

On average it also improves cognitive function slightly etc, but like most supplements individual results vary. “especially as you get older. But studies have not shown a strong effect.”
Good point about the files. Wix is a walled garden.

But cost wise, $20 a month is nothing. The first time they run into a WordPress security, theme, or extension issue, they'll spend more than a year's worth of Wix hosting to hire a dev to fix it.

The crawler companies just do not give a shit. They're running these crawl jobs because they can, the methodology is worthless, the data will be worthless, but they have so much computing resources relative to developer resources that it costs them more to figure out that the crawl is worthless and figure out what isn't worthless, than it does to just do the crawl and throw away the worthless data at the end and then crawl again. Meanwhile they perform the internet's most widespread DDoS (which is against the CFAA btw so if they caused actual damages to you, try suing them). I don't personally take an issue with web crawling as a concept (how else would search engines work? oh, they don't work any more anyway) but the implementation is obviously a failure.

I've noticed one crawling my copy of Gitea for the last few months - fetching every combination of https://server/commithash/filepath. My server isn't overloaded by this. It filled up the disk space by generating every possible snapshot, but I count that as a bug in Gitea, not an attack by the crawler. Still, the situation is very dumb, so I set my reverse proxy to feed it a variant of the Wikipedia home page on every AI crawler request for the last few days. The variation has several sections replaced with nonsense, both AI-generated and not. You can see it here: https://git.immibis.com/gptblock.html

I just checked, and they're still crawling, and they've gone 3 layers deep into the image tags of the page. Since every URL returns that page if you have the wrong user-agent, so do the images, but they happen to be in a relative path so I know how many layers deep they're looking.

Interestingly, if you ask ChatGPT to evaluate this page (GPT interactive page fetches are not blocked) it says it's a fake Wikipedia. You'd think they could use their own technology to evaluate pages.

Elon alienated the majority of the side of the political spectrum that actually can afford his vehicles. He then went on throughout Europe backing majority disliked right wing parties and utterly tanks his sales in Europe as well.

That's a big part of it, but there's also been a general pullback from EVs.
