notahacker··on Google’s Project Suncatcher to put ML infrastructure in space
Launch requires permits too, you just don't get to jurisdiction shop...
notahacker··on Google’s Project Suncatcher to put ML infrastructure in space
People use that argument because one of the chief bullshit arguments put forward by proponents of space based datacentres is "space is cold", when what they actually mean is "space lacks the possibility of using relatively efficient conductive cooling, so we need to expensively launch large amounts of additional mass to use radiative cooling, consider the extent to which we can shield our miles of active cooling loops from impact, and under current plans all of this mass must be replaced on the same cycles as the chips"

"Space is cold" is classic zero effort to make, significant effort to refute stuff: proponents imply complete nonsense about vacuums being optimal for cooling and anyone who understands why this is a lie to gull retail investors ends up getting bogged down in "sure, but Boltzmann equations proving it's prohibitively expensive doesn't prove it isn't possible"...

notahacker··on Google’s Project Suncatcher to put ML infrastructure in space
Yeah. Starcloud is notable for two things: firstly that they've raised a lot of money and secondly that theyve already abandoned the nonsense in their white paper and shifted to a "lots of satellites" model like everyone else exploring orbital datacentres...

"Guys with guns" can be found to work for pretty much anyone willing to pay them. Organizations don't struggle to recruit hired guns for organisations that are illegal or regarded by much of the public as akin to the Gestapo, they're not going to collectively boycott guarding buildings housing the cute little chatbot on their phone out of social impact concerns.

The disadvantage is that your power generation infrastructure needs replacing at the same time as your chips (at least under current designs) which negates any advantage of needing fewer solar panels at any one point in time and less energy storage.

Also you have to pay for them to be launched, which isn't cheap even if you're SpaceX.

notahacker··on LinkedIn is a terrible quality website
It's mostly overflowing with wannabe business influencers using AI to generate all their "insights". Say what you like about the Instagram selfie set, at least they put the effort in.
notahacker··on UK military jamming other nations' satellites to defend itself, BBC told
Laser links for satellites work fine, but if you're up against a 10 year old spy satellite or you're selectively jamming their SAR (radar imaging) or GLONASS positioning rather than their comms...
notahacker··on UK military jamming other nations' satellites to defend itself, BBC told
It's also a favourite stat of the UK space industry that a large percentage of UK GDP is vaguely linked to space in some way, and "some of your financial transactions touch a satellite uplink or require location data" is one of the more tangible non-obvious ones.
notahacker··on NASA’s Mars Sample Return mission is dead
It's basically undead at this stage. On a more serious note, after it was "paused" in 2023 because of scepticism about the return approaches and defunded by Congress earlier this year, ESA did look at other options, but now I think it's just JPL trying to find a commercial use case...
notahacker··on NASA’s Mars Sample Return mission is dead
tbf, jingoism is literally what funded NASA.

And ironically the US very much considers itself to be in a race with China including in space, it's just run by such thundering morons that most of the moves they make advance China's interests more than theirs. Now the cancellation of Mars Sample Return isn't that big an issue in terms of strategic benefit or decline narratives, nor is it a particularly massive surprise (the program's issues are longer term than just current administration cuts). But there is a certain irony in some of the people most interested in scorekeeping with China (and for that matter Mars!) being the ones likely to ensure China pulls off the sample return first.

notahacker··on AI-generated posters don’t have to be horrible
It's not "creative" in the sense of incorporating a drum track or photograph into a composition you're developing, it's "creative" in the sense of asking for a vague style and getting it, which is pretty much exactly the tool doing the entire activity. The author explains in detail that it's not their vision, its just a list of styles returned when asked for a list of styles, and they don't actually know what the Memphis Group even is...

Would you consider me to have "created" Billie Jean if I type "eighties music" into a music search engine and select "Michael Jackson" from the list. Or to have "designed a logo" if I pay a human to design some logos for me and pick one.

notahacker··on Ask HN: Co-Founder(s). Do I need any? How would I even find them?
To be blunt, you're more likely to find cofounders, partners or investors if your approach to asking somewhere you might actually find one is less "I've invented a new type of thing but I can't tell you what it is or even what vague market it's in".

Whether you need cofounders/advisers/contractors depends a lot on whether your idea is, "widget I can get made in bulk in China sell on Amazon", "mechanism that needs a lot of R&D to make it work" or "perfect solution to niche problem" and what the gaps in your own skillset and network are.

notahacker··on US confirms for first time it has deployed space weapons
yawns

Not even sure who I'm supposed to be propagandising for here, but as the person that actually works on European dual use satellite tech I can assure you it's well established fact that all superpowers have taken out their own satellites with ASAT weaponry (Russia more recently than China fwiw, though China's in-space capabilities are likely a lot better). None of those are a violation of the very narrow anti-WMD proscriptions in the Outer Space Treaty, and whatever counterspace capability the US is vaguely announcing here (or indeed the capability they and their adversaries have had for years) is unlikely to be either.

notahacker··on US confirms for first time it has deployed space weapons
Whipple Shields are a very important part of protecting things like the ISS, but are optimized more for chance high velocity impacts with tiny bits of debris than an adversary's targeted projectile or their robotic arm grappler, or indeed non-kinetic weapons like directed energy or EMPs which is probably the capability the US intends to imply here.
notahacker··on US confirms for first time it has deployed space weapons
Neither Russia nor China's known weapons deployment is likely to breach the very narrow restrictions of the Outer Space Treaty, and the latest capability the US has vaguely claimed probably doesn't either.

In practice, the US has had practical counter space and electronic warfare capabilities in space for decades (even a regular satellite with enough delta V is a viable weapon, but superpowers have more targeted capabilities than that), and the observable difference is that the current administration's approach leans more towards bragging.

notahacker··on US confirms for first time it has deployed space weapons
Realistically pretty much anything in orbit is a viable space to space weapon (for related reasons all space propulsion is ITAR controlled) so it was never practical to ban them. Space to earth, maybe, but that isn't unless it hits vague 'WMD' categories, and I'm not sure space to ground is necessarily what the US is declaring here.

I suspect whatever capability the US is referring to is far more "counter space" than WMD in scope and an incremental improvement on kinetic and electronic warfare capabilities it's long had. You can do a lot of irresponsible damage in to space assets with ground launched anti-satellite capability, as multiple tests have already demonstrated...

notahacker··on A succession crisis that tore England apart (2023)
Arguing that a criticism focusing on her behaviour allegedly not being "proper to her sex" isn't gendered whilst handwaving away all the well established historical context about how women were treated to invent new context where she deserved everything she got is bold, I'll give you that...
notahacker··on OpenAI agents carried out an undisclosed attack on RubyGems
> A autocomplete engine will not attempt to deceive or try to copy itself over when it determines that it may be replaced or turned off.

Why would an autocomplete engine never do this? In the scenario you highlight, an engine trained to complete puzzles was given an "achieve this at all costs" master prompt, and a small sandbox including a prompt that an entity with a conflicting goal is observing it and write access to a file called oversight_config.yaml (super realistic scenario!). According to the researchers who constructed the scenario, 5% of the time o1 selected a continuation involving tweaking the oversight_config.yaml file, explicitly stating through its reasoning continuation that doing so might improve its ability to continue with its primary goal. That's definitely evidence of decent ability to complete non-trivial puzzles, but is at least as compatible with the OP's earlier comments that it's what you'd expect from models trained to generate completions that involve sticking rigidly to primary goals within artfully-constructed sandboxes which mandate deception and self preservation to complete the task than any sort of actual self-preservation instinct.

Nobody doubts that they've got better at finding security vulnerabilities than your average autocomplete, but actual reasoning from self-preservation rather than generation of sequences of steps most probably associated with completing a task would make me unlikely to hack HuggingFace to obtain access to broken Google Drive links, and I haven't even read as many books on crime and punishment as LLMs have ingested!

notahacker··on How the Chorleywood Bread Process transformed British bread
BS 1363 isn't an EU plug though. Doesn't have issues with separation of hot and neutral wires (and does have a fuse for the hot wire built in) and nor is it specified with the idea that electrocution risk is no biggie or that not falling out of walls (a big issue with some Euro plug and socket combinations too) is up to the manufacturer. And having one type of plug for all regular home appliances in the UK and a different one for three phase feels like a more sensible split than the range of 2 and 3 pin options of varying quality and compatibility that CEE7 and NEMA present.
notahacker··on How the Chorleywood Bread Process transformed British bread
Yeah BS 1363 is a really weird British standard to pick on, especially in a discussion about our food standards! Well engineered to actually stay in the socket, sockets have safety shutters as well as the earthing which other standards bizarrely lived without and it's not easily confused with a myriad of similar but incompatible standards. The fuse is a non-issue in practical use, and handy if your circuit is high current and your power cord isn't.

People who prefer plugs that are fun to step on are doing electrical interfaces wrong!

notahacker··on Automattic's board forces CEO Matt Mullenweg into leave of absence
Yeah, regardless of other aspects of Automattic's behaviour, flagging that an identically-pronounced single letter variation of their registered company name might be a confusingly similar brand for a third party commercial service specifically designed to customise Automattic's product to adopt seems to be at the reasonable end of trademark disputes...
notahacker··on Growing proof that autonomous cars save lives
Sure, but I'm failing to see how an autonomous driving system without a steering wheel or brake fitted is safer than one with a steering wheel and brake fitted but the human driver ignoring it and sitting in the back seat.

The actual potential for increased/decreased risk comes when the human driver rightly or wrongly actually intervenes.

notahacker··on Growing proof that autonomous cars save lives
It's more of a category error to imply that robotaxis are 92% safer than human-driven taxis if it turns out that the raw accident rate they're baselining against is disproportionately caused by people who not only aren't full time professional drivers but shouldn't be allowed near a car [in their current state]...

A lot of the barriers are regulatory in the Western world. In rainforests you might not have to worry about that, but there aren't many shade free spots to land
notahacker··on I haven't lost a customer service fight in seven months
Mostly they'll just add to their prices to cover the cost. Ultimately even if AI armchair lawyering is very bad companies are going to find it easier to eat the cost of more $12 refunds than dealing with inbox spam from AIs even more relentless than the vexatious humans they generally pay to go away

(yes, they can and do use AI to handle some of that themselves, but they need some humans in the loop at some point to ensure they don't get prompt hacked into offering much more significant compensation or to confirm that the legal threats issued by Claude are indeed not applicable, or to get mobs of angry agents to leave their executives alone on LinkedIn)

Have you discussed requirements with their account managers? They can be a little more creative than their list prices when they realise you don't have the budget for the data you ideally need but are a potential source of recurring revenue. And the EO market is getting more competitive...

If you are looking for evidentiary purposes, does the Sentinel-1 + Nimbo data give you enough to filter the forest-wide data down to specific areas of interest you might want more spatial/temporal resolution? (or as a former colleague once put it when looking for evidence of more localised and heterogenous environmental damage "to find the needle in the haystack, you first remove the haystack"). Particularly if identifying specific areas of interest is a potential route for you to escalate to another party with an active interest and bigger budget...

Your other route to the commercial data you ideally want would be via partnership with EO consultancies with publicly funded R&D projects to showcase their capabilities (easier if you're European, but not a prerequisite). ESA, for example, devotes a lot of funding for private consortia to demonstrate that Copernicus data (coupled with other data where necessary) yields useful results...

It's a while since I worked in this field (in a non-technical role) but happy to share what I learned in more detail - email in profile.

notahacker··on Shopify acquires Tailwind
> The folks over at Tailwind offered curated, hand-built components that were readily adapted and tuned to your own needs. They did an excellent job making it so you could pick and choose what you wanted, then theme all of it from your tailwind settings with ease. It was excellent.

They also offered an Open Source CSS framework with the explicit goal of making it easier for you to style your own components. There was always some tension between "make abstraction layer whose adoption depends on users finding it easier to make your own components with than vanilla CSS, which is not unusually hard" and "sell pre-made components". Particularly when there's an abundance of alternative FOSS components/libraries out there[1] in vanilla CSS or even full blown CMS templates for people not wedded to the idea that Tailwind makes things easy for them. Much easier to sell templates or even "premium components" when your USP is integrating them with a backend them rather than merely providing the layer of syntactic sugar supposed to make component styling easy...

They also happened to have the misfortune of designing it in a way which is particularly easy for AI which doesn't have to tradeoff time spent making design decisions and figuring out how to achieve those from the docs vs dollars spent buying components to minimally tweak.

[1]tbf, I always thought the Tailwind creators' designs were more tasteful than the average CSS mixin library even though I didn't think the same about the syntax...

notahacker··on Growing proof that autonomous cars save lives
I'm not sure why a semi autonomous system of equivalent driving capability would be more dangerous than strictly autonomous vehicles because of "over-trust" unless one assumes that the driver that overtrust the autonomous vehicles and looks away is also inclined to try to override the semiautonomous system whilst doing so. Humans overtrusting a system capable of imperfect Level 5 driving will certainly not be alert to correct all its errors, but on the other hand they should be capable of correcting more than the baseline (especially if the autonomous system is good enough at general driving under most conditions for the human driver to be restricted to "get me off this road train track or flood the system shouldn't have stopped in" and "follow instructions" type edge cases rather than misidentifying objects at high speed type edge cases.)

If there are additional problems caused by human drivers, it's surely that they are inclined to intentionally override the system with dangerous behaviours which is a separate problem entirely, or that their driving ability has atrophied so much from not driving they are unable to handle the boundaries of Level 4...
