Ah, I see your point, I think. You are just pointing out that any repeating decimal is a ratio. Which, fair, but my question was if a bar representation was ever tried. The idea being that you don't need to have infinite storage to represent a ratio in positional digits any more than you have to use infinite paper to write a ratio's value out.

That is, yes, I know that 1/6 can be used to represent 0.1(6), but if you are already storing something in positional digits, there may have been a benefit to keeping it in positional digits? I'm assuming there was not, in fact, any benefit?

I prefer everything go through Apple b/c I trust Apple more than I trust the average other vendor.

This way, I know if I'm dealing with something on my phone, I have a trusted channel for commerce. I am sophisticated enough that I can probably ascertain what alternative payment schemes are reasonable and which are scams, but Apple's imposed payment monoculture means unsophisticated users are protected as well.

A more permissive payment setup would necessarily mean more scammy apps, or maybe just vendors with gross, dark patterns designed to obfuscate cancellation without quite being fraud. No thanks.

The commons are not destined to become a tragedy and they can become a long-term resource everyone can enjoy[1]. You need clear boundaries, reliable monitoring of shared resource, reasonable balance between costs and benefits, etc.

I kind of like data structures, because when you study them, and take them apart, and understand their pieces, rather than seeing the world as Prolly Trees here and Binary Trees there and Bloom Filters over there, you see a whole bunch of little tricks you can use, and when you collect a reasonably large bag of those tricks you can put them together in all sorts of ways.

It's almost a pity computers are as fast as they are and they are so rarely needed because having "arrays" and "maps/dicts/associative arrays/whatever" solves so many problems so much faster than we need anyhow. I don't get to pull out the bag of tricks very often. But then again, when I do, it's because it's a life saver and the difference between success and failure, so maybe it all balances out.

I have a side project Android app. To test Claude Code, I loaded it up in the repo and asked it to add a subscription billing capability to the app. Not rocket science, but it probably would have taken me a day or two to figure out the mechanics of Google Play subscription billing and implement it in code.

Claude Code did it in 30 seconds and it works flawlessly.

I am so confused how people are not seeing this as a valuable tool. Like, are you asking it to solve P versus NP or something?

If you need to do something that's been done a million times, but you don't have experience with it, LLMs are an excellent way to get running quickly.

We do not really know what causes misdirection of the immune system in the old age. "Boredom" (= underutilization) is just one of many hypotheses. Differences between lives of jungle dwellers and urban people are just too big to pinpoint one root cause (such as parasitic infestations). Various chemicals may also play a role, as may artificial light, differences in food composition etc.
Show HN: I built a tool to track ad-hoc SQL before they break schemas

I spent years as a data engineer debugging dashboards broken by untracked queries—Slack snippets, notebooks, and random scripts. Existing tools focus on enterprise lineage, not the daily pain points.

So leveraging my Python skills I learned django and built Tesser v1 to: - Track ad-hoc queries (Slack/Jupyter) that modify production data - Show which dashboards/tables they broke - Visualize potential impacts before query runs - Can fetch lineage data from WHs, databases and BI.

When someone runs UPDATE order_items SET price=0, Tesser: - Flags the query source (Slack user/notebook) - Shows affected dashboards - Estimates data impact

Built for: - Freelancers managing client data - Lean startup data teams without tooling budgets - Anyone tired of "who changed this?!" forensics

The UAE is currently conducting several large-scale infrastructure projects with a total value of US$772 billion, which is expected to bring ongoing steel demand, with 52% of projects still in the planning, design or tendering stages.

These projects include the $35 billion expansion of Dubai Maktoum International Airport, the Dubai Metro extension and the newly announced Disney theme park on Yas Island in Abu Dhabi. According to Emsteel's chief commercial officer Michael Lyon, an airport project alone requires 2 million tons of steel bars, and the subway extension line also requires 350,000 tons. In 2024, UAE steel demand has surged by 20%, showing strong market momentum. Steel demand is expected to grow by 10% in 2025, to meet the surge in demand.Emirates Steel, a subsidiary of Emsteel, has increased its monthly output from 260,000 tons to 400,000 tons, an increase of more than 50%.

Because the LLM is faster at typing the input, and faster at reading the output, than I am... the amount of input I have to give the LLM is less than what I have to give the search tool invocations, and the amount of output I have to read from the LLM is less than the amount of output from the search tool invocations.

To be fair it's also more likely to mess up than I am, but for reading search results to get an idea of what the code base looks like the speed/accuracy tradeoff is often worth it.

And if it was just a search tool this would be barely worth it, but the effects compound as you chain more tools together. For example: reading and running searches + reading and running compiler output is worth more than double just reading and running searches.

It's definitely an art to figure out when it's better to use an LLM, and when it's just going to be an impediment, though.

(Which isn't to agree that "context engineering" is anything other than "prompt engineering" rebranded, or has any staying power)

Interesting but too complicated for me.

For my own hashmap implementation I followed a wasteful aproach since I’m. It targeting embedded.

I created a structure called a hashmap object. It has two elements: a void pointer and a char pointer. The first one is the data and the second one is the metadata. The metadata is basically a string were the user can put anything, the type of the data, more data, whatever.

Then I preallocate 10s of thousands of hashmap objects. That way users of my hashmap don’t have to think about aollocating and de allocating hashmap nodes, they just insert, delete and search freely. They still have to care about allocating and de allocating they’re own data though.

Likely not for Gaelic, even in the Gaeltacht. I have a couple of friends who deliberately speak Gaelic to their kids, but neither of them would consider it their first language. The kids themselves are properly bilingual, but tend to default to English when visitors are present.

Scots is a bit different, because for many speakers it's just seen as an informal register of English. My grandparents, for example, were primarily Ulster Scots speakers - they could understand English but would have struggled to speak it naturally. My own internal monologue is peppered with plenty of Ulster Scots but fowk wid luck at me quare an funny if I were to use it much in my daily life in London!

> Amazon redefined convenience. SpaceX [...]. Apple [...]

What about the negative externalities? Are those all factored in the wealth?

Oil/coal have been opportunities to create whole wealth empires. Have they been worth it for everyone, not only billionaires, but societies, given their dire consequences over our own species (and others) survival in the next century? Has this part of risk been accounted in?

> They were earned through high-risk bets and long-term value creation.

And luck; really, luck is really under appreciated everywhere (both for good and bad fortunes). And cooperation from many other people and factors.

Not saying we shouldn't have billionaires. But we shouldn't have them so exempt from taxes, neither have them so powerful over state policies.

As someone who has actually built working micro payments systems, this was of interest. Worth noting though that it's really just "document-ware" -- there's no code there[1], and their proposed protocol doesn't look like it was thought through to the point where it has all the pieces that would be needed.

I do agree that the method is sensitive to X-scaling (and also Y-scale, which is logarithmic here!)-- but the "methodology" is at least defensible: scale X/Y to make existing data appear linear and make the "linear extrapolation in scribble space" meet the deadline at the middle of your X-axis.

I'm honestly kinda curious how well this "scribble-forecasting" actually works, but to me this sounds like it could be better than you'd expect from something this silly (but I honestly think that most utility comes from suitably picking between linear, log and semi-log plotspace, allowing you to approximate any linear, polynomial or exponential relationship with a straight scribble...)

Terrastruct looks really nice, and kind of like a 2D version of the 3D thing I'm thinking of; if you could attach key-value properties to nodes and vertices, and had different rendering modes that made use of any of these properties to render the item differently, that would probably be pretty close. For example, a layer that displays a physical network might only consider vertices with a `kind` attribute of "physical link"; that limits the layer to all nodes with a matching vertex between them, and the layer would also only display those attributes of the nodes relevant for the current view.

Does that make sense?

Hi, Wikipedia doesn't agree with you:

True.

> If it’s new construction I can inspect before completion (and you should); if it’s used, I am breaking the seal and crossing the streams. Attics got way too much “fun” to discover.

Don't do this! you can't see much anyway. At least not without walking up there and that disturbs your insulation. Everything you care about is about the roof working, so look at the roof from the outside. Keep the roof in good shape and you don't need to go in the attic.

Also until the house is yours you are not allowed to break that seal. Once it is your house you can do whatever you want, but it is too late.

Sounds like a classic example of Moravec’s paradox:

https://en.wikipedia.org/wiki/Moravec%27s_paradox

It’s not that a shooting (or action, or heck talk to competitive fighting game players) game has less decisions for the player to make, it’s that the decisions being made are all subconscious decisions about movements and difficult to put into words.

While most the manufacturing work has left the US, the Midwest is full of engineering universities. It's not a coincidence that the big 3 auto companies were based in Detroit and Michigan, Illinois, Indiana, Ohio, and Pennsylvania are full of top engineering colleges. There's still lots of nameless firms there designing all sorts of things that are manufactured across the globe, but they don't have the employee count to be massive drivers of a city's economy.

People don't even know what they are listening to. They might know some of the words in the chorus but the rest of the lyrical content is going straight into their subconscious minds while they bop along to a happy melody that's processed along a completely separate neural pathway to the lyrics.

So I'm measuring the lyrics with LLMs to build the first firewall for the mind.

The cynic in me says we'll be seeing articles about blog owners getting fractions of a tenth of a penny while Cloudflare pockets most of the revenue.

And of course it will eventually be rolled out for everyone, meaning there will be a Cloudflare-Net (where you only can read if you give Cloudflare your credit card number), and then successively more competing infrastructure services (Akamai, AWS, ... meaning we get into a fractured marketplace kind of situation, similar to how you need dozens of streaming abos to watch "everything").

For AI, it will make crawling more expensive for the large guys and lead to higher costs for AI users - which means all of us - while at the same time making it harder for smaller companies to start something new, innovative. And it will make information less available on AI models.

Finally, there’s a parallel here to the net neutrality debate: once access becomes conditional on payment or corporate gatekeeping, the original openness of the web erodes.

This is not the good news for netizens it sounds like.

Humans spend years training 24/7 before they can do anything useful. People train even during their sleep, in their dreams. And on top of that, we transmit culture to other people, which accelerate their training.

And that's with the huge "pre-training" data stored in our genetic code (comprising billions of years and evolution), alongside epigenetic inheritance.

AI generated code in all but the most trivial cases is never production ready.

In the real world, the resulting code that correctly and efficiently solves a problem ends up being unique enough such that an AI wouldn't learn much even if you fed this result back in. It's just going to average away all the important parts that made it correct.

If real world code wasn't so sparse and time consuming to develop it wouldn't be so valuable in the first place. Not to mention the fact that the maintenance is what you really care about and where the real costs are. Application code doesn't stand still.

As a TypeScript fan, I was really happy to read pretty much every one of these changes. This is a language I wouldn't personally use unless it gains massive traction, but one that I hope it gains massive traction so that I can justify spending the time memorizing and learning all these new language additions.

It's particularly exciting that they constantly rebase upstream Lua, and plan to update it to be compatible with Lua 5.5. Especially because Lua 5.5 finally has the ability to turn off globals!

Yeah, there are a lot of odd inclusions like that; things that overlap or replace standard lua flow for no reason (see ternary expressions[0]). I would love an expanded lua, with built-in classes and a more robust standard library, but this feels more like a rewrite into a new langauge with two vastly different design philosophies layered awkwardly on top of each other. Which it is I guess.

I don't mean to discount the work that has gone into it, and there are a lot of really neat features here. But honestly I think it would be stronger as a standalone thing, without all the lua baggage, given how far idiomatic pluto diverges from idiomatic lua.

Nobody will ever write a perfect law and you’ll always see cases like dark patterns when people try to unsubscribe from things or try to maintain their privacy, until there is proper enforcement and businesses start getting punished for violating the intent of the law. That is also unlikely.

>uninhabitable in a couple of decades

This is hyperbole, the Earth will be habitable for a very long time no matter what humans do. Using fear like that is the type of thing that ultimately hurts your cause. For example people who grew up hearing about how the ice caps were going to melt by 2020 and that Los Angeles would be underwater become more skeptical when they grow up and see that none of those scary predictions came to pass.

If you want to be taken seriously it is probably a good idea to dial back the “end is nigh” language.

Also suggesting solutions like banning meat, forcing people to buy solar panels (like in California), or instating regressive taxes that hurt poor people the most (California just added yet another tax on gasoline) are just not going to work.

Normal people see WEF talks about eating bugs and banning meat and think your cause is insane and dangerous. Honestly, they are mostly correct.

I understand, that USA is not homogeneous too!

> Have you ever left the Netherlands?

Rather no, as I'd moved to the Netherlands 2.5 years ago from outside of EU and don't have any rights to work outside the Netherlands :-)

It is not strict "No" because I've spent a lot of time (like, more than a yer on the span of 10 years, so more than month per year) in Germany on my previous work (in "business trips") and can compare everyday/household activities, but not bureaucratic or legal side of life, of course.

What I could compare is my experience as immigrant in the Netherlands with experience of my friends with same background as immigrants in Germany (lot of my friends had moved to Munich and Berlin same time I'd moved to Amsterdam). And difference is striking (in favor of the Netherlands). My experience with banks, IND (immigration department), Gemeente (municipality) and now even with mortgage (Which is cheaper than rent!) is much, much smoother that same experience of all my friends who choose Germany. Mortgage especially: no friends of mine could get approve for mortgage in Germany, even some of them who have salary significantly large than mine (like, x1.5 larger).

> (c) Enjoin Apple from conditioning any payment, revenue share, or access toany Apple product or service on an agreement with an Original Equipment Manufacturer (OEM)or carrier not to preinstall an iOS app distribution platform or store other than the Apple AppStore

Let carriers pre-load apps and app stores on Apple's products? That's insane.

> (d) Require Apple to provide rival iOS app stores with access to the App Storecatalog to ensure interoperability and to facilitate consumer choice;

Wait, what? They want access to Apple's App Store catalog? Also never going to happen.

> (g) Require that third-party application developers be given functionality and access to iOS application programming interfaces on terms no worse than the terms Apple allows for its first-party applications;

As sympathetic as I am to this notion, I'm not sure how it's reasonably achievable. Putting aside the burden of every SPI having to be supported, documented, public API, it would also mean opening up all security-sensitive SPI to the world.

Show HN: Get off your a** and do push-ups
by itsharveenatwal | 2025-07-01 14:00:32+00:00
I built an app where you LITERALLY have to do push-ups to use Reddit (or whatever app).

My guy, this is the summer you get SWOLE! Build a massive chest instead of doomscrolling on Hackernews.

Also, it's FREE. You can set it on a schedule. You can set it on a time limit. You can set it after X opens. Or even after you come home from work.

The apps will remain blocked until you do your push-ups!

The app is built natively on SwiftUI. I use Apple's native Vision API to detect body parts and joints. I use Apple's Screen Time API for app blocking.

I don't know what else to say so go on now and get the app!!

Actually this is wrong. There's a connection between bodily sensation and emotion so profound that quadriplegics can develop flat affect which in turn leads to decision paralysis and cognitive deficit. Emotions are regulated somatically, and inform decision making and other aspects of motivation and reasoning.
