<p>It really doesn't. You're purely relying on radiation fins to carry heat away, which are incredibly inefficient.<p>> The radiator surface area problem also scales uncomfortably. At 838 watts per square meter, rejecting 1 megawatt of waste heat requires roughly 1,200 square meters of radiator. Deploying that much surface area on a satellite is a structural engineering challenge that gets harder with every order of magnitude. The ISS solar arrays span about 2,500 square meters total.<p>So even a 2MW data centre in space requires a cooling array rivalling the international space station.
Starcloud launched a single H100 in November and they were unable to run it 24/7 due to heat buildup.<p>Even with novel solutions to make heat transfer to the fins more efficient, like phase-change liquids, the limiting factor is that the vacuum of space is a tremendous insulator.<p><a href="https://thecoolingreport.com/intel/starcloud-orbital-data-center-radiative-cooling.html" rel="nofollow">https://thecoolingreport.com/intel/starcloud-orbital-data-ce...</a><p><a href="https://satnews.com/2026/03/17/the-physics-wall-orbiting-data-centers-face-a-massive-cooling-challenge/" rel="nofollow">https://satnews.com/2026/03/17/the-physics-wall-orbiting-dat...</a></p>

<p>You do it to yourself, you do, and that's why it really hurts.<p>> Importantly, the company did not mandate AI use (though it did offer enterprise subscriptions to commercially available AI tools). On their own initiative workers did more because AI made “doing more” feel possible, accessible, and in many cases intrinsically rewarding.</p>

<p>This isn't a good idea regardless of why it's being deprecated.<p>If it's no longer being maintained then put a depreciation warning and let it break on its own. Changing a deprecated feature just means you <i>could</i> maintain it but don't want to.<p>Alternatively if you want to aggressively push people to migrate to the new version, have a clear development roadmap and force a hard error at the end of the depreciation window so you know in advance how long you can expect it to work and can document your code accordingly.<p>This wishy-washy half-broken behaviour doesn't help anyone</p>

<p>Western employment has survived because automating and outsourcing labour has pushed people to take up knowledge/services work.<p>If AI is somewhat successful at automating knowledge work, what feasible job could exist that doesn't require your mind or body?<p>Services like healthcare and plumbing aren't going away of course, but there's not enough demand to support an economy on those jobs.<p>In my opinion the whole economy needs a rethink regarding what our actual goals are as a society, and maybe AI will force that conversation to happen, but I'm sceptical if it'll be a well-considered consensus.</p>

<p>This is often made worse as a result of hiring outside consultants. Firstly they don't have the institutional knowledge you have when starting a project, but they also aren't incentivised to properly document and hand over their knowledge at the end since that means less future work.<p>This is why a lot of government projects take so long, they don't see the value in keeping an in-house team of trained experts (see the difference in train line contruction costs in the UK compared to Spain), until you realised how good they were but you can't hire them back.</p>

<p>To make 1 gram of antimatter, from E=mc^2, would take about 90 Terajoules. For reference, the atomic bomb that dropped on Hiroshima released about 60 Terajoules of energy.<p>So you would need at least (and with the efficiency loss of production, much more than) 1.5 Little Boy atomic bombs worth of energy to make a single gram of antimatter.</p>

<p>I'm not worried about the label, but I am worried about the implication - since software made the jump from physical to digital/OTA distribution, there's been a decline in software release quality because "we'll patch it later".<p>The historical financial punishments to writing buggy software are gone, and now it's infecting cars I'm concerned that safety standards will begin to slip and potentially injure someone.<p>Side note: I know a common response to buggy software is the market won't pay because it takes longer to develop etc. But writing robust software is a hard skill,and it you haven't seen an industry write robust software for a long time, why should you trust they still can?</p>

<p>Tech isn't siloed for no reason.<p>In the UK government, before programming was considered a high-value skill, the vast majority of programmers were women. So much so that programming was measured in girl hours (which were paid less than man hours).<p>When it became clear that programming was going to be a big deal, women were systematically excluded, flipping the gender balance (although they had trouble hiring initially because men saw it as lesser work).</p>

<p>Maybe, but it was already public knowledge:<p>> In September 2023 the government regulator, the Office of Rail and Road (ORR), had issued an improvement notice to Network Rail about overcrowding at the station, warning: “You have failed to implement, so far as reasonably practicable, effective measures to prevent risks to health and safety of passengers (and other persons at the station) during passenger surges and overcrowding events at London Euston Station.”<p>It's concerning to me that Hendy was the chair of Network Rail from 2015  before becoming Transport Minister, and here he is sacking someone after a comment about his former workplace. Should definitely be an investigation into his motives/incentives IMO</p>
