I think you need 1 hp per 10-15 lbs of weight to fly. I think that's around 130 W/kg. I checked a piper cub is something like 100.

Other hand Pu-238 produces 570 W/kg. A piper cub with it's 48kw engine would need 87kg of Pu-238 to produce the same energy.

I looked up the cost, $1968/g. So 48kw would cost $171 million.

Interesting idea but doubt.

I agree that applying anything to do with blockchain to electricity is dumb - these are already just regular markets, so an inverter/charger could already take price signals from the existing market and do whatever the homeowner wanted, with zero need for blockchain or central control at all. With smart meters (which are becoming more ubiquitous) it's already simple to incentivise using battery power in peak periods when the price is high...

But on inverter/chargers - they will absolutely will follow a downward trend. Maybe not as quickly as batteries but downward all the same. Wide-bandgap semiconductor FETs are getting cheaper and better all the time (higher current and voltage per device), and they allow for power topologies that are more efficient, so cooling gets easier, weight of heatsinks and the amount of material in those goes down, power per unit volume increases and unit mass will decrease, etc. Production volumes will also increase which should lead to economies of scale too.

I can get a 48V DC/230V AC, 8000VA Victron Multiplus 2 inverter/charger for $1.8K USD at the moment (I'm about to buy one for a system I'm DIYing from 31 kWh of AGM batteries I managed to get basically free from a test site of a company that closed down). I wouldn't be surprised if I could get the same capacity inverter/charger for something nearer to half the price by 2030, and a few percent more efficient to boot (this is 95% max efficiency but hopefully 97-98 will be more common by then).

You probably can get plenty of cheaper ones from China already but I want to be absolutely sure it'll meet Australian Standards since this will be grid tied for backup (but able to operate independently during outages), and since it's going under my house I want to know it's safe! Victron have a good track record, especially with a lot of use in maritime and caravan applications where you really don't want them catching on fire so that gives me confidence!
I got one of the lapdocks for the Atrix a few years after the Atrix because you could hook it up to a Raspberry Pi and it'd work. Broke the HDMI port at some point though, mini HDMI is just too fragile.
That's very relevant to generate-and-test program search.

The SBSE (search-based software engineering) and APR (automated program repair) communities do that kind of stuff. E.g.: There's a paper from that world, which I can't presently find, on "super mutants": basically, use environmental variables as feature flags so that you can compile 100 variants at once. Back when I worked in this space, one of the best things I did was run the Java compiler from within nailgun (program that saves JVM startup time) to compile mutants faster.

Symbolic program synthesis doesn't work like this. They effectively has its own compiler toolchain that transform programs into constraint systems and/or do partial evaluation of programs with wholes. Most of them never run a traditional compiler; they just guarantee that they output correct code.

You don't need a company to sponsor you for a bank account in Japan either, but if you just moved into the country, they do want to know who your employer is. Same for landlords: why would anyone rent you an apartment if you don't have an income?

Where did you get the idea that you need your company to help you set up a bank account? I was able to do it easily at 2 banks all by myself.

For those of us who live in a bubble, what AI hype is out there?

I recently had a problem cross my desk which the stakeholders thought might be solvable with an LLM, which may have been true, but ultimately was more easily solved using plain old boring programming techniques. Is that the hype?

While the final solution didn't need to involve LLMs or anything of that nature, I don't think said stakeholders would have been able to even envision the possibility of trying to solve said problem had semi-recent technological developments that has taken on the AI moniker not enabled them to think more creatively about what machines might be able to do. Without that, there is little chance I would have become aware of the problem someone faced.

If that's the AI hype, I'm game. Being able to get computers to do things others didn't think was possible is what brings me to the world of software development.
I'm an European and I get zero spam calls.

I used to get a couple of cold calls per year for surveys, but I got unlisted via GDPR requests and now its down to zero.

Companies do try collecting your phone number, but then I answer NO to the obligatory "do you want the latest offers" question (in the EU, this is opt-in not opt-out). And it doesn't matter if my phone number leaks.

This is similar to my email address use. I used to get emails from recruiters, but after a couple of replies informing them that whatever profile they have is illegal, with my email address not being public, asking them to delete it, the emails stopped. I still get spam, but it's mostly fraud and US companies. Fastmail's spam filters are good enough, BTW.

My phone number works just fine, and the phone network is valuable given the better signal 2G can have, or the fact that not everyone is on the app du jour. And I find it odd when people call me on WhatsApp.

I frequently see US folks criticising GDPR, so I'm guessing this is one of those "the US mind can't comprehend" moments.
Structured log formats are not "plaintext" logs
> While this sucks, my phone is in so many data breaches at this point it doesn’t matter.

Yes, and this is the slope that we keep sliding down with these data breaches not being taken seriously. First it was your name and email. Now phone numbers. What's the next bit of our private info that we'll normalize leaking?
I think this is mostly dead for a reason. TUI nostalgia is an itch for software people, but software people already have more powerful things--like SQL, Pandas, APL, etc... while spreadsheets are for people who don't want to scale those learning curves, and those people already have Excel.

> Blockchains certainly have a future as it's a highly useful technology

No trolling here; I promise. Are you saying that blockchain is already "highly useful technology", or that we will in the future? From my perspective, it is a very cool technology concept that has yet to demonstrate any major commercial value. I also seriously doubt it will be commercially valuable ever; it has already existed for more than 10 years without any killer app (ignoring shitcoins).
Yes. No CB or CR channels.
Rossman’s right about a lot of things, but sometimes he’s a bit too harsh and a 39 minute video on what was obviously a puff piece and MKBHD is not a journalist seems like a bit much.

Personally, I've begun switching over my RP2040 projects to Rust using Embassy. Rust did take some getting used to, but I quite like it. Not an RTOS, but it satisfies a lot of the same requirements that'd lead you to an RTOS.
I have learnt over the years, that rather than calling a specific skill "soft" or "non-technical" to actually learn it and get good at it. Along the way I have learnt a great deal about the unknown unknowns.

We have a progression: unconscious incompetent -> conscious incompetent -> conscious competent -> unconscious competent. And it is completely context and domain specific.
> The fact that Meta rather inexplicably chooses to give away assets that cost millions or billions to create doesn't mean LLMs aren't a product

Real question: Why are so many LLMs given away for free? Are they hoping to crush non-free alternatives?

EDIT

Your last paragraph makes an excellent point. In the near future, I could see big corps paying OpenAI (or a competitor) to train a private LLM on their squillion internal documents and build a very good helpdesk agent. (Legal and compliance would love it.)
I think this a consequence of the open-source marketing strategy of big tech companies and commercialization the parent talked about. When developers use open-source, most of the time maintainers are paid and it’s part of their job, and of the parent company’s strategy.

In this landscape it’s unfortunate but I think one way to avoid this especially if published on GitHub is to be upfront in the README that this is a hobby project with no support, only to be used professionally at your own risks (buried in the license is not enough). Otherwise if projects are presented too similarly to professional ones it’s fair to expect developers to be confused, it’s just unfortunate to what GitHub has turned and that the burden is on hobbyist maintainers to differentiate now but that’s where we are.

And also unfortunate is the practice of resume building by publishing professional looking projects on GitHub that adds to the confusion.

> Lifepo4 (lithium iron phosphate) batteries for the home are pretty cheap as of today. Power storage for residential use in a 48v metal rackable linkable system with battery management system (BMS) is $89/kwh shipped/duty paid from reputable chinese suppliers CATL/Seplos etc.

I'm probably not the only one wondering: does ordering from these Chinese suppliers require reaching out to them over email? I looked at both websites, and while Seplos asks to write in, CATL doesn't even have battery listings or sales contact information.

I'd love to order LiFePo4 batteries to put in some old UPSes of mine.

Haskell is actively a hindrance if one is mostly moving bytes from one place to another: the only thing that matters when you need to talk to 7 databases each different is fashion. The language that has bindings to all 7 each with a zillion users is the one you should use.

If you’re moving a lot of undifferentiated bytes the language you should use is historically C, more recently C++ (which is still the standard), or maybe soon Rust (which looks to become the standard).

If IO is a small part of your problem, performance needs to be good but not insane, and you’re mostly thinking about algorithms and mathematics?

Haskell is a very pragmatic choice there. OCaml is strong here too, and TypeScript is a very cool compromise between “mainstream” and “we do math here”.
I have been thinking about a useless TOTP app that works the other way around. Instead of giving you the current code, it gives you the timestamps when the code is e.g. 000000, 123456 or 777777.

With a window of 30 seconds and 1e6 possibilities, the expected time it takes to get to a particular number is 347 days. Should be easy to brute force.
ARM remains a shitty backwater of unsupportable crap ass nonsense being thrown over the wall.

Qualcomm bought Imageon from AMD in 2009. Sure, they've done some work, made some things somewhat better. But hearing that the graphics architecture is woefully out of date, with terrible compute performance is ghastly unsurprisingly. Trying to see thing thing run games is going to be a sad sad sad story. And that's only 50% the translation layers (which would be amazing if this were Linux and not a Windows or Android device).

the pi pico is 100% supported in Zephyr. https://github.com/zephyrproject-rtos/zephyr/tree/main/board... Did the author not check the docs? https://docs.zephyrproject.org/latest/boards/raspberrypi/rpi...

Additionally, you aren't intended (for many situations) to use a single "main" Zephyr install, but to include what external modules you need in your project's west.yml. If you have a number of projects sharing the same Zephyr install that's a separate discussion but installing every possible toolchain/HAL is not the only way to do things.
Show HN: CRM-like conversational voice AI platform for phone and web
Hey HN, we're building a conversational AI solution focusing on end-to-end task automation instead of creating voice tools for developers. We'll see if it's a good idea or not, we're ready to pivot.

I wanted to do our first public announcement here and I'm excited to let this community try and I look forward to your feedback.

YC invested in such products lately, follow them all, awesome tools. It's interesting to see that we meet the same problems and often we conclude on the same solutions. I love and recommend Zexia's (CTO, Retell) blog post about building a tool like this - they are open about the components and I agree that you can surely built yours but takes a lot to figure out the nuances.

We have got building blocks and properties that we currently align to each use case.
To tell about the tech shortly: we don't use Deepgram. The rest of the stack is as you'd imagine (OpenAI/LLama, 11L).
We do the VAD and STT in-house, we have our hosted and fine-tuned models, we're operating our own GPU machines.
We support multiple services of LLM and TTS and you'll be able to bring yours. For example, we have Google, AWS, Azure TTS to be up-to-date of their capabilities and for some languages they are good.
We will use Deepgram for TTS, maybe for STT, we plan to keep the ASR and streaming/chunking/etc. parts in-house.

Our platform with public registration is not ready yet, releasing this summer but you can try the calls on our website.
More info and use cases with public trial will be available in a few days.
Please, be gentle and use it with good intentions so we can keep it publicly available.

> For AI infra startups to be “venture scale”, they will eventually need to win over enterprise customers. No question. That requires the startups to have some sustainable edge that separates their products from the incumbents’ (GCP, AWS, as well as the likes of Vercel, Databricks, Datadog, etc).

On the surface, I agree. But look at a parallel market segment: Cheap cloud hosting. Think: Linode (or any of its competitors). There are a bunch of cheap cloud providers who are more than 10 years old. They didn't all get bought out nor bankrupt by up-starts. Why? They must add just enough value to stay in business. Could we see something similar in the AI infra space? In fact, it looks more logical for the cheap cloud providers to try to build some AI infra -- low hanging fruit, to help with LLM training. (I am sure they already see GPU time.)
I am writing a book the premise of which is “software Literacy” - the ability to code is a major inflection point.

a little backstory (that seems to be missing from the blog post). this is a technique that was invented in the early days of google for deduplicating the crawl set (turns out that building an llm and building a plain ol' web text index look awfully similar; i wonder why that is?!). you can read about it in depth in jeffrey ullman's free book "mining massive datasets" which describes many of the really cool and impressive techniques that were used to prepare an index build for the entire internet when such a thing was really hard.

you can find the relevant material for free by searching "chapter 3 pdf mmds ullman"

enjoy!

edit: oh no! i'm wrong! according to wikipedia it was invented at dec for altavista. https://en.wikipedia.org/wiki/MinHash either way there's a nice description in the ullman book and they do describe how it was used at google as well.
I'm pre-burned on all hype. If people are excited, I know to ignore it while it's devalued in the search of value.

> in the software industry today, I think technical skills have been undervalued

Is there a particular niche in the industry that you've seen this? I've almost universally seen the opposite.

The closest thing I can think of is that someone who truly only has technical skills will usually be limited to IC levels, whereas someone who also has soft skills becomes a better candidate for senior and staff positions. The thing is, that's because soft skills are an actual requirement for those roles. The purpose to them is to herd cats, and someone who communicates poorly or doesn't seek out opportunities to do so won't get them.

With that said, I don't think I've been in any tech focused company where technical skills aren't valued, and continued growth unappreciated. It's more a case that they're considered table stakes, and having strong soft skills is where you stand out.
Blindsight by Peter Watts.
