It was made for different use cases.

Nobody had a personal computing device in their pocket 90% of their awake time.

Now the goal for product department is to make their newly "smart" devices accessible to said computing devices.

The simplest solution that (almost) always works on home networks is to initiate an outgoing connection to an external server (the "cloud"), push notifications and poll for commands; after, have the mobile app only talk to the server.

If you do anything else, you are at the very least setting yourself up for support nightmare: "I am at home and I can't access my washer through the app" (are you on the same network? maybe your phone has wifi turned off?)

For usecases of the sort, this is one general solution that — from the perspective of a PM — always works.

By simply discounting reality that it's more expensive to implement both locally accessible smart devices, yet keep remote capability, and discounting that support costs are going to balloon too, we are not driving to a positive outcome for all of ourselves either.

I think we should focus on getting the cost down, by building better tooling and protocols and patterns that make it easy for a mobile app (or any client) to discover and talk to any smart device, making it simple for a customer to decide if they want remote capability or not.
This is true but also very complicated. I have tried very expensive microphones and I have tried cheap microphones and which one is better is conditional to location, and deployment.

I use a røde lavalier tieclip which is awesome, and surprisingly cheap. It's also very omni. I had a USB-C enabled podcaster microphone which was awesome and very directional but it also was a giant lump in front of my face in zoom.

On the whole, a tieclip and some minor level setting works, but I just can't control the lawnmower outside and with an Omni, it's leaking in.

getting high Q sound and directionally limited but not in your face in anything but a pro sound studio is hard. I suspect the sound isolation in a studio also has some issues: a certain amount of the real world leaking into your voice isn't a bad thing. "it depends"

also: get trained. My company paid for me to do a course with the Australian Film and Television School and it was delivered by a far north queensland radio professional who was not condescending, not nasty, and very good at explaining how to do speak-to-microphone without a crew to help you. Worth every penny. Oh yea: those "ad hoc" recordings? 99% planning. There is no such thing as ad hoc in the radio, if you can avoid it.
Thanks for the corrections and a deeper dive!
...according to investors. (ps. it's even >$150B)

In reality OpenAI is loosing money per user.

Cost per token is tanking like crazy due to competition.

They guesstimate break even and then profit in couple of years.

Their guesses seem to not account for progress much especially on open weight models.

Frankly I have no idea what they're thinking there – they can barely keep up with investor subsidized, non sustainable model.
Several years ago, I had a Dutch girl apply for a traineeship-level position with my business in Australia, and she included a number of photos, including a 'glamour' shot of her straddling a chair. Quite bizarre.

Haven't you been communicating? Can you understand why your co-founder is choosing the current (new?) path? You don't need to agree, but you do need to understand what premises are leading to the decisions. Is your co-founder even aware of your disagreement?

How much equity do you have? How much equity do the outside investors hold? Are the outside investors supporting your co-founder's direction? Are you the tech guy and your co-founder the biz guy?

If your co-founder is so confident in the proposed direction, is he willing to buy you out? If not, why not? What about the outside investors?
100% agree on building a system and not aiming for perfection. Do you solve most of those issues with internal tooling or are there some public tools you've found effective?

Bluntly, if you have to ask on hacker news, you are not equipped to handle this situation and should look to either exit or enlist more capable help. Your quandary is so contingent on the specifics of you, your cofounder, and the competing directions of the company that no good advice regarding a direct action to take is possible here. That you would ask in this forum is a very bad sign that either communications have broken down or you have not attempted a conciliation.
the last executive order was that bitcoin can only be acquired using “budget neutral” strategies in addition to stuff the US Marshals already had

so now they have found budget neutral ways

our gold reserves have been valued at $42 per troy ounce for like 80 years

their market value is $3000 per troy oz, so selling them at market value doesnt adversely impact the budget because they werent part of it to begin with
300 years? Listen if you can’t ship product then it doesn’t matter how good you are or what your rep is. Pack it in and hit code academy or coursera or whatever and skill up.
The complexity of a relational database is usually very much needed, with all the joins, subqueries, etc.

The poster complains about query plans being unnecessarily dynamic; for certain queries, it should be pinned, and only changed in a controlled way. Compare it to something like pip or npm; not being able to pin versions of certain packages could be a source of endless frustrations.

Pinning a query plan to a query could very well be a feature of a relational DB, an it is. Postgres (pg_hint_plan extension), Oracle (a bunch), MS SQL (somehow), they all have ways to pin the query plan. Not sending SQL is calling a stored procedure, also a long-standing feature of relational databases.

Knowing your tech stack goes a long way in battling frustration.
> Conversely, filesystems are often implemented using B-trees as many RDBMSes are but aren't designed for many of the operations one might typically ascribe to a database.

Filesystems are not a relational database, sure, but the word "database" in the context of computer systems, computer science, IT and technology in general doesn't mean "relational database".

Filesystems are definitely a hierarchical database, which is different to a relational database.
It wouldn’t make a difference

Show HN: Open-source Android app to record raw data from Polar devices
There seemed to be no open source app yet to record raw biosignals from polar devices, so I build one.

It’s aimed at researchers, developers, and anyone interested in working with raw biometric signals.

Would love any feedback!
Spreadsheets: no index, not a database.
The problem with china is, they will have to figure out latency. Right now DeepSeek models hosted in china are having very high latency. It could because of DDoS and not strong enough infrastructure but probably also because of Great Firewall, runtime censoring prompt and servers physical location (big ping to US and EU countries).
I'll chime in with a related project: https://openpipes.org
Another one with an, “I dunno, 5 maybe?” story. I had a heart attack 2 months ago and got asked the 1-10 thing 4-5 times in the middle of it. I had classic left side chest and back of my arm pain. Kinda made up a number but told them I definitely felt shitty.

I did ask my cardiologist how she’d rate my heart attack on a scale of 1-10 for severity. She laughed and said nobody had asked her that before. Then said 7.
Which puzzles had the lowest solve rate? I did the first 10 and felt all easy (mentally solve it in 10-20 seconds for easier ones and 30-60 seconds for harder ones), I’d like to try the most difficult ones.
This is great to see, thanks.

There's so much time spent (dare I say wasted) on building and tweaking materials by teachers that it feels like an area AI can make a huge impact, directly improving the quality of life for a large number.

Not sure what it's like in Australia, but in the UK many teachers are expected to create materials in their own time (or just don't have enough time in the day to do so).

Oftentimes it's something that's been taught previously, but the teacher has a learning objective in mind, and so needs to tweak the existing presentation.

Love seeing some focus in this area.
My bad, I messed up with WebP images optimization, should be working now, thanks for letting me know!
Yeah; my comment specifically called out Windows, but to be fair, all the GUI systems at the time had the same restrictions.

It was convention across all GUI systems.
It's impossible to conclusively say whether dazzle worked or not, due to the large number of confounding variables. One study, which I unfortunately forget where I read it, came to the tentative conclusion that it was probably mostly a wash. Yes, dazzle helped somewhat and there was as a result a slightly lower percentage of successful attacks (that is, more torpedoes that missed their target), but OTOH due to being easier to spot in the first place the dazzle painted ships also invited more attacks.
May be I remember it wrong. But when CUDA came out it also replaced Cg ( C for graphics ) which at the time was used or at least aimed to fit a lot of massively parallel workload into it.

While strictly speaking the two are very different. I would tend to think a lot of the idea and work of CUDA came directly from working on Cg. And CUDA's history could at least span to its introduction in 2001.

And of course in a separate interview Jansen claims that was the Goal from day one the company was founded and Graphics was only their starting point.

In any case, their success is anything but luck. Name of a single company that invested into a side quest continuously and rigorously for 15 years before they hit any sort of jackpot. Most would have given up. The beauty of founder company versus returns to investor.
I remember that when it first came out. I get it’s a theoretical or fashion type thing, but the concept seemed flagrantly absurd to me. Block automated facial recognition in a way that in turn makes your face instantly recognisable in any crowd…

that requires dynamic scoping right? Wouldn't work in lexical scoping.

Jeff, you left out the juiciest part of the story, which is that the Bosch Home Connect iPhone app hoovers up your Search History data. Anyone know how much that data is worth? I made the same mistake of buying the 500 and it's just so ridiculous that I need to reveal my most intimate Google moments to a dishwasher in order to use its advanced features which I won't. When I was building Internet technology in the 1990s and optimistic about the future, never in my fiercest nightmares could I have predicted that this is how normies would use it and that it'd be considered normal. What kind of monster do you have to be to use home appliances as leverage to spy on people? There seriously needs to be a different planet for people like us.
> how well git plays with pre-epoch timestamps?

Tangentially, most RSS readers don't play nicely. A lot of webtooling doesn't like featuring e.g. old poetry etc. with the actual dates e.g.: https://alexalejandre.com/poetry/ I got a few e.g. newsboat to update their handling though.
A K-V store by construction has an index (over K). But you seem to also want referential integrity and transactions, not small features, limiting the implementation quite a lot.

You can attain what you desire by using an RDBMS, and having all tables with one key column, and a TEXT column with your serialized non-key fields; it's going to be a fun approximation of 6NF. Realistically, you can have all joinable columns as normal columns, indexed as you desire, and the rest of the columns as a serialized blob.

When you want high parallelism for guaranteed independent segments of data, use sharding.
KV databases are also the least efficient architecture possible if your data models or workloads are non-trivial. They are relatively simple to design and build, which is a positive attribute, but they are not that capable in any kind of theoretical sense. Other architectures preserve far more spatial and temporal locality when representing data models.

If your workload has even a whiff of analytics to it, operational or slow-time, KV databases are almost the pathological architecture in theory. Their intrinsically poor locality exacts a steep performance price.

These database architectures are all equivalent in the same sense that almost everything is a Turing Machine. Some manifestations and implementations are much more efficient than others in the real world. While I am not as emotionally invested in it as the article’s author seems to be, he is generally correct that KV databases have poor properties for most applications.
BCPL had a lot of features C didn't have at this point and still doesn't. You mean B.
What would be an argument that this platform sucks less?

I don't want to record videos of me presenting myself.

LinkedIn seems simple. I post a CV and I toggle if I am open to work or not. Recruiters can find me and I can search for jobs and apply to them. That is all the functionality I need apart from having lots of jobs available on the platform.
Why not just use Bluetooth? I'd be suspicious if the Dishwasher app requested permission to access the phone's microphone
the bodybuilding scene has gotten more advanced than just steriods, for example:
- SARMs (selective androgen receptor modulators) - eg ostarine - they hit your muscles androgen receptors selectively, nominally other receptors (ie reproductive) are skipped over
- SERMS (selective estrogen receptor modulators) - typically used to reduce gynecomastia after steroid use, but interestingly one, clomiphene or enclomiphene, blocks estrogen reception in the pituitary, making it think hormone production is too low - so tells your body to manufacture more testosterone (yes, estrogen receptor blockage yields testosterone production).. this is the closest we have to a fertility drug and is prescribed as a fertility drug in women
- cardarine - PPAR delta activator, activates metabolic pathways and used by athletes for doping - quite an interesting drug because it normalizes one's metabolism, increases athletic performance, lowers cholesterol, etc, wow! though to activate a particular minor cancer pathway.. never tested in humans since it gave animal models turbocancer. used by many athletes

But yea, most of these are going to blanket increase risks for various things - strokes, clot, heart attack... messing about with hormones can be quite damaging albeit I would take a SARM or a SERM before taking straight hormones. Cardarine is quite scary because of the cancer concern
You usually want a query planner, else you'll end up writing a query planner yourself to produce efficient queries.

What is sometimes needed is query plan stability, lack of surprises, and influencing the planner. This is very attainable in the existing SQL databases and is a core feature of the older ones, like Oracle.
Was it really designed this way? I keep hearing this claim but I don't think Ritchie himself actually confirmed that?

Also, notice how the functions call each other from wherever, even from different files, without need of any forward declarations, it simply works, which, as I have been repeatedly told, is not something a single-pass compiler can implement :)

I wonder, is Postgres a bit of a large DB if it's just a personal website search tool?
I'll have to give it a go. We need more tools like this.
Most electric cars already have user interfaces that surpass current ICE vehicles to a significant degree.

Tesla, BYD, KIA EV9, Polestar, their user interfaces are already fantastic.

It's whether Apple could make a material improvement on what is already out there for top EV cars.
I am wondering if a BTC rugpull is inevitable. For the whales, why not just transition to another coin.

They see potential, they jump in on new coin, new coin flies. I don’t see why they wouldn’t. Microstrategy, musk and trump can collude. I don’t think there are any regulations stopping them. I don’t see why they wouldn’t, either. Unless they are worried about PR or that is just a difficult way to increase wealth.
"Some amount of mental health care" and "widely available mental support for free and with urgent response" are vastly different goalposts.

[CW: long-ass heavy-duty story happening closer to you than you think.]

I don't know what your mental health history is, but one of my friends had to use a VPN, then lie about their location to a volunteer operator, in order to access a suicide prevention chatline on the other side of the globe, just to have someone help them keep it together while their ex-SO was actively driving them to suicide - or worse.

They also had to move to the middle of nowhere so that the ex, or the friends of the ex, wouldn't be able to randomly show up at their door. The (widely lauded) only domestic abuse hotline in the country did exactly half of nothing whatsoever, shout out Animus foundation, hashtag slay queen.

I wish I could've somehow helped to resolve that whole situation, I was probably the only one of their acquaintances who even had any idea what they were going through; all the same, at the time I was stuck in my own cycles of psychological warfare. There's only so much support you can provide without getting dragged down with them, you know?

Perhaps a trained professional in a therapeutic environment can help somewhat more, but would they be able to help sufficiently to get back on their feet someone who has been failed by the entire societal edifice starting with primary caretakers? Not necessarily. I mean have you even seen some of the sorts of people that become therapists? They might as well be vibe coders!

This is in EU, though admittedly not the "former colonial power" part of the EU. So you end up presuming quite a lot, just because where you live the state has taken some more organized measures to prevent people from freaking out (at realizing what's going on around them, hehehe.)

xoz123 gets it. Sometimes there is no non-adversarial person available. Sometimes it's absolutely overwhelming to be the only adult, small and powerless in a room of powerful overgrown toddlers. Sometimes you're the only sane and conscientious person, forced to conform to a culture of self-important violent psychopaths. Sometimes it's all that, plus the state wants to punish you for the fact that you suffer. Most of the time, you're on your own, and that alone serves as sufficient ground for being subjected to censure.

And sometimes it's worse. I seriously worry about how much worse it can be made with the help of some AI that is trained to be more familiar with these type of phenomena than any civilized person cares to be, and has none of the basic restraints.

I actually think that in a virus scenario humanity would be able to bounce back fairly quickly (meaning 100 years instead of 10,000), presuming there is a solution for the virus

Why? Because the virus doesn't actually kill infrastructure. Many roads and bridges will be ok-ish sitting around with no load for a while. Many factories and tools will be mostly in tact. Most importantly though, it infra will be fine. A laptop with a backup of Wikipedia can sit around for a few decades, and generating some electricity locally is not that big of an issue.

That would kickstart humanity's recovery. We don't need to reinvent the wheel, just read how someone else did it
Anecdotally, I didn't smoke or drink and was celibate during college and I dropped out twice.

My sister drank a lot and was very promiscuous and went on to become a doctor.

I think doing well in college is probably more about factors like time management skills and social support network than about vices.

>on building and tweaking materials by teachers that it feels like an area AI can make a huge impact

Yes absolutely. Teachers are swamped with having to create learning materials all the time and that's how SlideHero started off. I was using ChatGPT to help me brainstorm and draft content and the penny dropped that creating a structured presentation tool would be a huge win. I've used it a lot in my classes and it has been a huge timesaver.
I work for AMD. To be clear, my new job is about integrating ROCm into the distribution not just about shipping ROCm packages that can run on Debian.

I'll be doing things like creating new packages in main, helping to get support for the HIP language embedded into existing dpkg tooling, helping to get GPU architecture awareness integrated into the Debian CI infrastructure, helping to enable ROCm support in other libraries and applications packaged for Debian, and ensuring that everything in Debian is successfully imported into the Ubuntu universe repositories.

Integrating HIP support into Debian so that it feels as natural as C or C++ and 'just works' across dozens of GPUs is a job for more than one person. That is why I'm glad there have been so many volunteers in the community stepping forward to help with various pieces.
It's funny you mention UI, because for me this is the first place I'm experiencing this, in web development: LLMs are better at the 'brute force' nature of e.g. Tailwind (inline UI styling) vs. needing to handle the abstractions of indirectly-applicable CSS classes. That's a really small, high level example, but to me it demonstrated how less abstraction actually makes prediction easier for the LLM.
