Caltech's approach[0] is to make their satellite with solar panels on one side and a transmit antenna on the other, so pretty much the whole area of solar panels serves as a giant phased array transmit aperture. They claim that this approach can be made very lightweight and might only mass 160 g/m^2.

Kilometer space structures need not be very massive, as the loads they are subject to are quite small. More often achieving a certain stiffness, such that the structure doesn't wobble around too much when being repointed, drives design more than resisting structural loads. The main loading case they consider in [0] is solar radiation pressure.

Making the entire structure coherent gets interesting as it's expected to flex a bit. However, they have demonstrated methods to correct for this flex[1].

One problem they have is that their satellite has to consist of a number of smaller spacecraft connected to each other in a grid because they can't launch the whole structure at the same time. One person involved with the project had concerns about how they would align each spacecraft to within subwavelength accuracy.

I was thinking a mix of genetics and diet. More the former than the latter, seeing how Ireland isn't a Blue Zone country. I wonder what his diet and routine was before he took up rowing.
Tons of counterexamples: Windows Mobile, PalmOS, Symbian, even dumbphone operating systems like S30 allowed J2EE apps. Of these, the strictest control was exercised in the J2EE ecosystem, which could be (and often was) configured such that only programs signed by the OEM could run. But that was an extreme case, because all smartphones operated with what kids these days called "sideloading." "Sideloading" used to be called "installing" and you didn't need to do it with a specific piece of software run by the company who issued your operating system.

If your spouse also makes 3000 euros you can totally live very well and raise a family.

I am not deluded thank you. I don't have a family but I live with 1200 euros a month around Paris and although I am poor I am nowhere near miserable. Of course most people own houses thanks to parents participation and of course Paris is too expensive duh.

Now I am curious to know what's your standard of living.

Mh, I work quite a bit in the OPs-side and monitoring and observability are part of my job, for a bit of time now too.

I'll say: Effective observability, monitoring and alerting of complex systems is a really hard problem.

Like, you look at a graph of a metric, and there are spikes. But... are the spikes even abnormal? Are the spikes caused by the layer below, because our storage array is failing? Are the spikes caused by ... well also the storage layer.. because the application is slamming the database with bullshit queries? Or maybe your data is collected incorrectly. Or you select the wrong data, which is then summarized misleadingly.

Been in most of these situations. The monitoring means everything, and nothing, at the same time.

And in the application case, little common industry wisdom will help you. Yes, your in-house code is slamming the database with crap, and thus all the layers in between are saturating and people are angry. I guess you'd add monitoring and instrumentation... while production is down.

At that point, I think we're at a similar point of "Safety rules are written in blood" - "the most effective monitoring boards are found while prod is down".

And that's just the road to find the function in code that's a problem. That's when product tells you how this is critical to a business critical customer.
> Obamacare was, and is, a disaster, driving up costs while producing worse outcomes.

I'm not sure I'd call it a disaster, but I will agree that ACA did absolutely nothing to address the core issue:

Health care is just too expensive.

I crashed my mountain bike in the summer of 2022, broke my arm and scraped up my knee real bad, though managed to put my bike back on the rack on my car and drive to the ER one-handed. They did an X-Ray, confirmed the breakage, gave me an arm sling and a prescription for painkillers, and cleaned up my knee. Total visit was 20 minutes. Without insurance, it would have cost me nearly $3,000.

$3,000 for 20 minutes of work between an X-Ray tech, 1 doc, 1 nurse, and 1 person at the front desk.

I understand that there's overhead, but I still think that cost was 5x what it should have been.
I would actually love to work on soundcloud. I use it everyday to discover new music, new mixes, new artists and its amazing. In particular, DJs, from all sizes, uploading their sets, it introduces me to such a breadth of new music and new sounds and then you dig through the comments to find IDs (people that identified which track is played in the mix), check out the artists and their guest mixes - and discover new music constantly. There are alteratives (mixcloud?) but I would deeply miss soundcloud, much more than any other service (like spotify, netflix), because unlike those I feel like soundcloud has a lot of content that is not hosted anywhere else.. i even wonder if its archived somewhere or if one day it will be all lost.
On top of all that, SoundCloud has (probably) the most positive and supporting commenting culture of any of the bigger platforms.

I follow the mastodon bot https://botsin.space/@soundcloudsaid that sprinkles random happy little comments in my timeline.

Much of my work the past few years has been working with Amazon's seller-side e-commerce APIs, and it's truly infuriating how impenetrable their "support" systems are. It's ridiculously hard to get even basic problems solved, and for some reason they make it near-impossible to get access to shipping and tax addresses via their APIs [0], which makes developing pretty basic functionality really difficult.

> Solar roads are expensive and worked out economocially nowhere, where they were build.

This is exactly my claim for fusion: an uneconomical idea that sounds really cool in theory.

> the basic idea of fusing hydrogen into helium works without radioactivity.

Where does the deuterium come from? There's going to be neutrons bombarding everything, by design, all sorts of radioactivity. It's literally at the core of the entire thing. This point is swept under the rug, but ensuring that the radioactivity is short lived will be a major design requirement of most components for the reactor.

> scale challenges

The scale challenge might be building a small reactor, instead of a large one. We don't know what sort of containment will work, and at what sort of physical scales. Which is why massive construction projects are a problem. We are terrible at massive scale construction, and much better at small scale manufacturing.

> fusion bombs

Not sure why fusion bombs would indicate we could ever do sustained and controlled fusion reactions. These are entirely different processes with almost no connection to each other. This is an error on the order of magnitude of thinking that fusion is not radioactive.

And this is why fusion is solar roads for sci fi fans. People love solar roads because they don't know the particulars about solar panels and roads and why they are a bad fit for each other. People love fusion power because they don't know the specifics about fusion or power and why they are a bad fit for each other.
> don’t actually look similar to each other

I think this should be “more similar than other groups” rather than simply “similar”. Even then I think it’s possible that some groups have more loci with higher diversity for facial features. That’s not even getting to epigenetic and environmental elements.

I think the deeper truth is in your final paragraph: facial similarity is in the eye of the beholder.
But neither of them function reliably as a telephone (I own both), although the Librem 5 is much closer to that goal than the Pinephone.
It's not even clear that breaking up the app stores would be good for consumers or developers. Having to load an app onto 15 different app stores to capture the market sounds like hell.

The only ones who would really benefit are other large corporations like Epic.

> I've had to self-diagnose and then just plainly guide several of my doctors, even specialists, on diagnostics (for evidence) and subsequent treatment.

Being involved in your own treatment is very important. In my opinion, it’s folly to expect your doctor to know everything. I can read descriptions of similar diseases and problems and be able to compare my symptoms. You generally know your body better than anyone.

Funfact: This is dangerous!

We have a bias towards believing written information. Even if we are told "What you are about to read is wrong", you are then more likely to believe what you've read than before you read it.

At that point you're making a very banal point about the moral status of Hamas. But Hamas has no moral status, so metering it in ever finer units isn't moving any conversation forward. We agree: Hamas is very bad.

Regarding enforcement: Semiconductor foundries are physically large and require extremely high-precision equipment and very pure materials. They can easily be detected and can be isolated via blockades. Once the global superpowers are on board with the Initiative, each superpower can enforce the ban within the territories of their sphere of influence. There is no motive to cheat, none, because this is a matter of our children's survival. Cheating on the ban even a little bit directly threatens the survival of your own children and grandchildren. Additionally, all of the superpowers possess satellite surveillance capabilities which can be used to track global supply chains and ensure everyone is being honest.

The most important thing is to prevent all new fabrication of IC's, but I believe that as a compromise, it is acceptable to "grandfather in" already fabricated IC's.

Existing computers and phones could be allowed to continue to exist for as long as they can be kept running. With careful stewardship of this resource they should probably last for several centuries, with batteries being swapped for new ones every few years. Current computers are probably not fast enough to run true AGI, so this should be an acceptable level of risk and makes the Initiative more palatable to society.
Exactly.

- no need to enter a CC number in another site (and maintain it)

- no need to create another account to make that payment (or unironically use Apple Pay flows)

Maybe I'm fortunate, stupid, or a combination but not being able to pay for Netflix using Apple subscriptions really bugs me and I'd pay more to avoid it. Which reminds me I need to cancel it...
> low density, with oversized buttons and excessive whitespace.

That part is mostly because of smartphones and their small touchscreens. You don't really have a choice with these fat fingers.

And for consistency purposes for multiplatform apps/webpages, desktop interfaces followed.

The unfortunate thing is that we have had smartphones for 20 years and no one could develop a paradigm with good desktop and mobile ergonomics. UIs improved massively from the 1980s to the 2000s, but from the 2000s to the 2020s, there is essentially no improvement. I understand the disruption caused by smartphones, but not the lack of progress. If anything, modern UIs are objectively worse than they were 20 years ago. Look at that mess that is Windows 11, nothing is consistent, even when you only consider what is shipped with the OS itself.
Yeah, but that’s not really your sole source of inspiration. My son has been ‘inspired’ by the art of all other kids in his kindergarden. Certainly by the time he gets to the age where he does it professionally he’s been inspired by an uncountable number of people.
Distracting is right! I watched your CrystalConf video and was happy to see the familiar Postgres + Redis combo :). I remember worrying about running out of legs with Redis (being single threaded), but with a combo of pipelining and changing the data structures used it ended up being the piece of infra that had the most headroom.

Monitoring was probably the biggest value for outsourcing to another SaaS. I used Runscope, AWS dashboards and own elasticsearch and it was pretty cost effective for the API that was doing ~2M API calls a day.

The other risk of cloud solutions is the crazy cost spikes. I remember consulting a partner, much larger, weather company on reducing their costs of a similar global weather product where they chose AWS DynamoDB as their main datastore, and their bill just for DynamoDB was twice our companies cloud bill. All because it was slightly "easier" to not think about compute requirements!

Any ways, thanks for the postmortem, hopefully your channeling of quiet wisdom continues to branch out to others! :)

But moral/ethical, and/or sufficient compensation?

IMO (and it is just opinion), the damage GenAI does to IP value happens when, and only when, an AI is good enough to make some human unemployable, and that happens to all e.g. novelists around the same time even those whose IP was explicitly excluded from training the model. So, twist question: is it fair to pay a UBI to people who refuse to contribute to some future AI that does end up making us all redundant? (My answer is "yes, it's fair to pay to all even if they contributed nothing, this is a terrible place for schadenfreude").

Conversely, mediocre regurgitation of half-remembered patterns that mimic the style of a famous author cannot cause any more harm when done by AI than when done by fan fiction.

Right now these models are pretty bad at creative fiction, pretty good at writing code, so I expect this to impact us before novelists, despite the flood of mediocre AI books reported in various places.

Other damage can happen independently of IP value damage, like fully automated propaganda, but that seems like it's not a place where compensation would go to a copyright holder in the first place.

Sufficient compensation? If AI works out, nobody will have any economic advantage, and UBI is the only fair and ethical option I am yet aware of for that.

It's what happens between here and there that's messy.
Polyfill libraries can provide methods that were added in newer versions of the language (e.g. to std lib classes), but they can't provide the new syntax that has been added.

Ruby has had a lot of syntax changes over the years that are incompatible with an older interpreter. An easy example is the 1.9 shorthand hash syntax for symbol keys `{ name: "pants" }` instead of the hashrocket syntax `{ :name => "pants" }`. More recent examples would be keyword args or pattern matching.
I do love a good pint of Guinness. There's something very satisfying about how it looks; the more pronounced flavor than other globally available macro beers, and how it seems easier to have a few more than it would be with other beers.
These models are not conscious, they’re not acting on their own. If I make art using a generative model it’s no more the model doing it than it’s sketchbook doing it if I were to use that. I’m making art using whatever tool, sometimes that tool is more or less powerful. But I’m the one doing it.

Yes, exactly. Or 5 cents for the first 100 searches, 2 cents after, something like that.
I wonder if that idea is compatible with something like caesium standard time. Is causality at work in the frequency of atomic resonance? (Separately, I would be inclined to disagree that we directly perceive causality.)
Nah, my theory is you're seeing run-of-the-mill brash business dealings with the unusual characteristic of being broadcasted publicly.

You wouldn't accuse the same of CEOs from more 'boring' companies because we only get exposed to the results through sterile PR communication, despite the fact the same candid conversations still happen.
I love this channel! Yeah, I wish I could just buy a new one of these toasters. That’s basically exactly what I’d like to build. I would personally pay a good premium for one, and I think there is probably a decent number of people who would as well. It would be a niche product, but still maybe worth pursuing?
Yes, exactly my point. You compare alternatives and come up with value.

Yeah, PCI writes can be posted. It's still very very slow and will end up using an inefficient small transaction size on the PCIe side of things. And posting doesn't help with reads, of course. PCI devices that are cache coherent and can cache snoop and otherwise work with WB cache mode can be written a lot faster. UC writes are something like sequentially consistent (program order reordering with other operations is not allowed) which limits the OoO / superscalar magic the CPU can otherwise do to make code fast.

I like this series as an intro: https://xillybus.com/tutorials/pci-express-tlp-pcie-primer-t...
I haven’t done the math or really thought about it all that much but one reason could be that space has a lot of, well, space. You can build a huge array without wasting land that could be used for something else, condense the power down to a beam and send it to earth.
You clearly have never used these other tools. Mixtral / Deepseek perform very well on coding challenges. I've used them against local code without issues, sometimes they are a bit optimistic and produce too much, but thats far better than producing too little (like GPT4 does).
If we're talking about the API, it seems like it's short because it is shorter. The latest version of GPT-4 (1106) might have a significantly larger input window, but its maximum output token size is limited to 4096 tokens.

It's likely that ChatGPT uses the 1106 model underneath the covers or some variant, so it probably suffers from the same restricted output window.
This is something that every start-up company ends up going through at some point. I’ve been there and it’s painful!

Sometimes you just don’t have enough time or resource to build the capabilities that would stop an issue like this. Sometimes you didn’t even think a particular issue could even happen and it comes and bites you.

The transparency is important, the learning is important, but also (sometimes) the compensation is important. Kagi should consider giving some search credits for the time that we were unable to use the service. Especially as the real-time response was inadequate (as they freely admit).

An outage for a paid-for service is not the same as an outage of a you’re-the-product service
Thankfully most everything lily-go throws on their boards is pretty generic and generally adafruit has an equivalent feather wing or some such, and you can use their documentation to figure out how to get your lily-go stuff working with a bit of time spent cross referencing schematics and code.
This is a good question, and I completely agree that programming them can feel... strange.

We approach this as two separate problems:

1. Can Chapel utilize tensor cores under the hood? We have LinearAlgebra and BLAS (and LAPACK) modules in Chapel. They have not been integrated with the GPU support so far. But we want them to be able to use libraries like cuBLAS for GPU-based array under the hood for GPU-allocated arrays. That model can enable Chapel to exploit tensor cores efficiently and seamlessly. Of course, you can extrapolate this to ML/AI APIs and potential Chapel modules correspond to them for example.

2. Can Chapel enable general-purpose tensor programming? This is definitely more challenging, where the main challenge is whether we can make tensor programming portable in such a way that the same code can be used on a non-GPU (and non-vector) processor. Probably a relatively shorter-term solution is to provide a low-level interface that's not much different than CUDA's Warp Matrix Functions or ROCm's rocWMMA interfaces and live with that for a while even though it is not portable. One of the thoughts that I can ignore is whether general-purpose tensor programming is _that_ common vs using tensor cores under the hood through some library as I described in (1).
To address your last point...

It's not because people in third world countries don't think about it that it's propaganda.

It's not about doing something about it, it's about not putting out in the world a person who is going to have it worse.

Why do you care so much about renewal ? What is it you want to renew so much ? A gene pool ?
Over the past ten years, lenses have gotten unbelievably better. Apsherical elements have done some of the lifting, and glass formulas another, but how much have computational tools changed how lenses are designed?
I found the article explained exactly why using fluorite helped chromatic aberration. It adds another degree of freedom, due to the partial dispersion.
This was always going to catch them eventually... Being a music storage system with streaming always has limits either in storage space/customers or bandwidth. I mean, alot of artists are paying for accounts to store their songs for years but the balance of that and all the millions of ppl streaming/downloading from those accounts? Limits. It's a fine line.

Seems like up to a point it would be a fixed number too with the upper limit of new artists willing to pay for accounts (which have more than doubled in cost since the beginning) dwindling. And throw in the ongoing evolution of copyrighted material detection etc etc (which they seem to straddle constantly, allowing mixes and such but definitely preventing direct song uploads more recently I have noticed)
But the owners/capitalism is surely demanding continued growth so I dunno what SoundCloud has been telling them for the last seemingly 5+ years unchanging.

Perhaps all the free accounts need to go away too, but that hinders creative growth/opportunities that there just aren't as many on the net. Part of SC's initial boom was because there was no easy place to store and share some music.

We continue to run up against these challenges and there's no clear solution. See also related/similar bind at Bandcamp.
