Except that you still can't sell the house or you won't have a place to live, so they've only improved on paper before you account for the opportunity cost of the higher imputed rent, i.e. the higher cost of living. Meanwhile you could have gotten the $50k HELOC against the $400k house, which was the only part doing anything that would actually affect your life.

Wasmtime's fuel metering makes applications horribly slow.

Is there a better way (NOT epochs) to deterministically track fuel usage of applications such that the fuel is incremented after certain blocks of code instead?

Because in blockchain based applications, we don't NEED to stop the execution after an exact fuel count, we need to overall stop it after a limit (even if it is slightly over the limit).

The performance would be improved significantly is this can be implemented or can be enabled through some configuration.

Former game dev here, drenched in cold sweat! Drop anything you are doing and immediately erase any mention of the 4-letter genre (words 3,4,5,6 in the title of your post). It is trademarked term and the holder goes VERY aggressively after it, including it's 4 letter acronym. I strongly suggest deleting the GitHub repo if it contains that phrase and create new GitHub repo without it. Use something like "interactive adventure" or something like that.

The x11 will be supported for 1.5 more years in latest state. And then there will still be support from LTS distribution for bug fixes. Only new features won't be there. It seems very glacial to me still.

> This is a perfect use case for long term support (LTS) distributions shipping older versions of Plasma. For example, AlmaLinux 9 includes the Plasma X11 session and will be supported until sometime in 2032.

Recently I tried Electron app, it didn't work out of the box in Ubuntu 24.04 (AppImage). Turned out some issue with apparmor. It worked if extracted manually, though, but that's a bit of friction for ordinary users, also probably wouldn't work with updater.

I think that's the issue: https://github.com/electron/electron/issues/41066

Not even sure who to blame in this situation.

The ability to ask "stupid" questions without feeling embarrassed is a superpower IMO.

I had the sweetest manager once. Someone stared talking about iphone and she [1] casually asked "what is iphone?" (this is after 6-7 months after iPhone was launched). Everyone's jaw dropped ... what? In which world u live in? ... to which she said with a wide smile and not an ounce of embarrassment .. "what? I don't know what iphone is?"

But she was otherwise so good in every other aspect ...

[1] She is/was mother of 4 kids and that left her very little time for anything else.

Refer to the "Macintosh Technology in the Common Hardware Reference Platform" book for more information, if you're curious about the Mac IO pieces.

The Motorola Yellowknife board seems remarkably similar to this system, as well as the IBM Long Trail system (albeit with Long Trail using a VLSI Golden Gate versus a MPC106 memory controller). Both of them use W83C553 southbridges and PC87307 Super I/O controllers.

The architecture is kind of weird, but the schematics on NXP's website can probably elucidate a bit more on the system's design.

> but movie making is also energy intensive - people, sets, cameras, shooting, rendering, editing, etc.

Do you have at least the order of magnitude for this? Does it also consume as much water as data centers? Has the entertainment industry ever needed to attract US$7T within 5 years to do what it does?

> “AI is supposed to help humanity advance faster and make humanity more productive.”

Is it? How? Will it really advance life or it is just a probability? Advance in what way, and why do you think being faster is better, and if better, better at what? If it is a probability, what exact number is it? What if it doesn’t happen in the way you think it will?

It's a numbers game - even if you kill only a part of the pathogen with fever, it actually makes a big difference in the end, since in the initial phase it grows exponentially. Also, another indirect benefit is that when you have a fever, you tend to rest more rather than pretending everything is rosy, and when your immune system works best, it is when you sleep. In the States, I've seen many irresponsible sick people who go to work and take Tylenol so that they can cope better at work, essentially spreading the disease.

In many cultures, instead of giving you Paracetamol/Acetaminophen at the onset of fever, they would actually warm you up to give it a boost.

I know, stoicism is gone - people can't tolerate any pain, any discomfort, any trouble nowadays.

I use it for a lot of stuff, but ultimately redo almost all of it - which I think is right.

The LLM is the mush of everyone's stuff like the juice at the bottom of the bin is a mix of all the restaurants food.

The writing out the other end of the LLM is bland.

What it IS useful for is seeing a wrong thing and then going and making my own.

I still use it for various little scripts and menial tasks.

The push for this stuff to replace creativity is disgusting.

Sticking LLMs in every place is just crap, I've had enough.

I own a Neato robot and I’m on the fence how I feel about it. On the one hand, it bothers me to no end that a shitty architectural design makes it so my robot loses half its functionality when the company goes under.

On the other hand, Neato went very bust a long time ago. Vorwerk bought the scraps, and I’m thankful to them keeping the servers on this long. They could’ve totally structured the acquisition such that all customer obligations ended with Neato (and who knows, maybe they did), but they kept it on even though Vorwerk never made a single euro from me. I wish they’d keep it on longer and fix/duct-tape the security issues, but can’t really fault them for not wanting to.

If you read Clean Code and other similar books, they don't necessarily advise moving the sub-functions to other files, or splitting them arbitrarily. They simply have the top function delegate to sub-functions that are lower in the same file. Even better if these sub-functions can be marked as private in your language (to avoid polluting the public API of your object). And here the goal is to use function names to document what each block of code (sub-function) does.

Example:

def process_order(order): _validate(order) _reserve(order) _charge(order) _confirm(order) def _validate(order): ... def _reserve(order): ...

> Because zoning reforms that allow higher density may lower the value of the house

For most detached single family homes in in-demand areas where housing (and thus sustainable population) are constrained by the supply of housing units, they probably won't do that, either; not only will they increase the land value, the fact that they increases population while decreasing the supply of ainglet-family homes will drive up the price of existing single family homes.

What it does, though, is reduce the use value (experienced utility of use) for current owner-residents for whom the particular local character is a factor in enjoyment, and make alternative replacements with the quality that is now missing from the current home that are in the same area (and thus compatible with existing jobs, etc.) harder to find, as well.

No I don't. But I wanted to call that out.

Is it? How? Will it really advance life or it is just a probability? Advance in what way, and why do you think being faster is better, and if better, better at what? If it is a probability, what exact number is it? What if it doesn’t happen in the way you think it will?

These are all decent questions. I don't have the answer. However, I do know that movies and shows are for entertainment. They do not enhance productivity.

In my limited experience (enterprises like energy companies is the biggest tech areas I've worked in, code order of magnitude <1M LOC, at best a few hundred engineers), as a senior developer the best thing you can do is create a culture, good examples, and automated checks and balances. Linters and code formatters, procedures, good examples (because in that kind of world most code is copy/pasted from something similar and adjusted), and nowadays, AI prompt documents that give these tools hints to what code should be used as an example.

But even then, given time and number of people, bit rot and a slow downwards spiral feels inevitable. Which is why in those industries they will often do a rewrite every 5-10 years, especially in front-end. Often a redesign / rebranding (also every 10 odd years) will be used as an excuse to rebuild software entirely.

Yep, that's the major problem with Apple hardware nowadays. It is very good in term of quality (at least if you don't need too much RAM of storage) but for the price you are entirely at the mercy of Apple for long term support. And recent Apple behavior has shown that they drop support on cue, regardless of the actual capacity of the device. I think they have actually become way more aggressive in that regard to boost sales, because the reality is that recent progress isn't really relevant to most people. Without forced deprecation, many would use their device almost indefinitely.

It cannot be a good deal to buy an expensive device that is guaranteed complete deprecation in a 7 year window (and very likely to suffer some major annoyance at the 5 years mark).

If you buy an equally expensive Android device (or Windows PC), because the model is different, you'll fare much better. And the reality is that at equal characteristics/performance the Android/PC version is generally quite cheaper.

Apple aficionados will rave about the build quality and ecosystem but I think they are irrelevant (most of the ecosystem advantages are to be found in the alternate world) and the devices feel more premium than they are actually qualitative (in fact they are very fragile in many ways).

They are surfing the Apple Silicon wave but as their efficiency lead is shrinking it will lose relevance/power.
Show HN: I built 19 AI agents because one wasn't enough to coach my workouts
by danielepelleri | 2025-11-29 09:43:02+00:00
Hey HN,

I've been lifting for years and got frustrated with fitness apps that either (a) generate a static plan and forget about you, or (b) require manual logging with no intelligence. So I built Arvo—an AI personal trainer that adapts after every single set, not just at the start of your workout. Why 19 agents instead of one? Each handles a specific job: - Exercise Architect (selects movements based on equipment/goals) - Load Navigator (calculates weight adjustments based on RIR) - Volume Manager (tracks MEV/MAV/MRV per muscle group) - Pattern Scout (extracts insights from natural language notes) - Movement Adapter (biomechanical weight conversion when swapping exercises) They coordinate to make decisions in <500ms. Example: You finish set 1 of bench press, felt easy (RIR 4). Arvo bumps weight +2.5kg for set 2. Set 2 was a grind (RIR 1). Arvo keeps the weight but suggests longer rest.

UK has the feature that you can bootstrap new towns because from the new town you are probably within 1000s of jobs in neigbouring towns.

Without a precisely timed neutron initiator you'll get a fizzle. Either way, gun-type bombs require highly enriched uranium. A simple reactor can be literally just brickwork of natural uranium and graphite.

Reactors are much much simpler to pull off, which is why US had the first reactor whole 2.5 years before a nuclear bomb.

We noticed this in our logs once! We service a huge amount of traffic, and as part of that, we log what is effectively an enum. We did a summarization of this field once, and noticed that there were a couple of “impossible” values being logged. One of my coworkers realized that the string that actually got logged was exactly one bit off from a valid string, and we came to the conclusion that we were probably seeing cosmic rays in action, either in our service, or in the logging service.

Oh, neither do I. We see eye to eye on this point - it isn't good at the things people have learned to be good at, and that's a good thing.

What it excels at is empowering people with good ideas about architecture and function to explore them without being burdened by SCRUM, or managers, or other such trappings of large orgs. A solo dev, who has a hot take on a new way to structure a cluster or iterate on a dev tool, can just throw the pasta rather than spend tons of time nitpicking boilerplate and details with a team of 10. Someone who uses computers a lot but doesn't know how to do specific thing x or y can now discover that in seconds, with full documentation and annotations and (most importantly) links to relevant non-AI learning material.

What I feel like people are getting wrong most is this idea that AI is coming for your job and it's going to be a powerslave to the MBA types who can then kick the engineers out of the picture. It's not happening (if anything, enabling smaller teams to get more done is going to deprecate the large org outside of the places it's not needed). That's the bubble, and while gargantuan amounts of money go to these AI startups it's all going to fall on it's face when they realize that what AI allows us to do is bootstrap good projects without megalith VC bucks.

Wow, that brings back memories! I remember reading this years ago, and it made me change my programming style a bit. The copy-paste errors he mentioned especially opened my eyes, I realised I was doing that too. For writing repetitive "0,1,2,3" or "x,y,z" code I switched to using Wolfram Mathematica's symbolic expansion and simplification followed by a C code generation step.

Which is apparently something which is currently in oversupply since housing in the suburbs costs less per square foot than it does in even the higher density areas that are within the same commuting radius.

Meta note: I think we should be angrier at Apple and Google over this. It’s in their interest to push everyone and everything to the cloud (their clouds ideally) and so they never pushed for great local connectivity solutions in their phone OSes.

There’s not really a good reason why it has to be hard for a device to connect to a nearby phone over some reliable signal, eg a home’s existing wifi network. (HN disclaimer: yeah yeah, i know it’s possible, but it’s a big hassle and the UX sucks so a manufacturer is effectively forced to go cloud if they want a device to be controllable from an app). The industry could have long developed some fancy protocol/system over wifi intended for just that. But device manufacturers aren’t strong enough to push for that in networking land, and Apple/Google/Microsoft have an interest against “local” becoming a normal thing normal people can figure out.

I feel like this is what regulation should be about. Instead of demanding that companies open source their systems if they go under, IMO we should have rules saying that smart devices shouldn’t need internet access for controlling them from nearby. If rules like that are in place, a push for a way to make the UX for that as good as it is via some cloud server will automatically happen.

My CTO, when told that adding scope, reducing headcount, and keeping the same timeline all while discovering new unknowns in the codebase was not possible, we were simply told to make the date and asked who's performance review will be impacted. The "no" was entirely ignored. "I don't accept that."

How do you say no in that situation? Just quit?
LX: A CLI tool for LaTeX notes management

The concepts in the LLMs latent space are close to each other and you find them by asking in the right way, so if you ask like an expert you find better stuff.

For it to work best you should be an expert in the subject matter, or something equivalent.

You need to know enough about what your making not just to specify it, but to see where the LLM is deviating (perhaps because you needed to ask more specifically).

Garbage in garbage out is as important as ever.

I am puzzled that the media is widely reporting that the issue was caused by solar radiation, and that the immediate fix is to revert to the previous version of software for the ELAC (Elevator Aileron Computer). The only explanation that seems to fit with the narrative is that the newer version of software has weaker memory integrity checks than the older version - which seems unlikely.

I don’t have any data or links to contribute, but my gut feeling is that this effect would be dwarfed by population movement, specifically urbanisation - if rural areas are emptying out as everyone moves to the city, you can get the same patterns (e.g. reduced housing supply in cities and all the flow on effects from that) without any change in total population.

I tend to think in images without an internal dialog running. If I think about an upcoming trip I will imagine a series of images related to the trip, possible places to go, or just generally the place. After a bit a potential conclusion appears fully formed in my mind. If I think about a work problem, I might imagine the document, a coworkers face, or something like that while ruminating on it. Basically it feels like the subconscious is handling the details and the conscious self overall directs it.

Occasionally there is some snippet of a sentence I imagine, but it’s almost always cut off prior to finishing the sentence. If I imagine writing something, though, I’ll speak it to myself in my head.

Funnily enough, I’m a pretty weak mental visualiser too. I don’t have aphantasia but metal images are very transparent and dark.

Wire was able to implement a fully E2E-encrypted messenger with proper multi-device support almost a decade ago, long before it became mainstream. Fully FOSS too, including the server. For some reason it never became popular. They don't have proper desktop clients (just the usual Electron mess), but then, which one of them does except for Telegram?

https://github.com/wireapp/wire-server , etc.
