He is almost certainly a better overall programmer"]]></title><description><![CDATA[
<p>I wonder if what you're noticing in Fabrice's code is a lack of _abstraction_ beyond whats obviously needed to get the job done. It's not spaghetti IMHO, I think its what code looks like when you're smart enough to just hold most of the problem in your head. I am speculating a bit here, because I am not that smart.<p>If I had to describe it in aesthetic terms I would maybe say brutalism?</p>

<p>I use hermes with crons and kanban for this. I have a "self driving" homelab where upgrades & config changes happen in a non-prod ct before being applied to "prod" (just, a diff ct). Its mainly compose stacks with data volumes on zfs that gets snapshotted a lot to limit possible data loss. I use the orchestrator to break down regular tasks like "health check the whole env" or "find all containers that need an update", "update terraform providers" into changes with their own card & MR, actioned serially via kanban. The task detail is just in playbooks in the repo, like a human would use. Executed by qwen 3.6 27B. I still use claude to help define and oversee workflows though.<p>Probably CI is the better primitive, I usually use gitlab though and I felt "put off" by all their native AI features being license gated.</p>

Not technically impossible"]]></title><description><![CDATA[
<p>> You and I can still trade with each other, no robots need be involved.<p>Unless one of us happens to be a food producer we will both starve. We need our trade graph to be connected to resources we need.<p>Production also tends to need exclusive access to resources (land, materials, etc) and you will be competing with machines for access to those.<p>> The reason we have an economy and money and trade is that we need to incentivize people to produce all the stuff that people consume, and manage those finite resources constrained by people’s finite time. But you can do away with all that messiness of all that exchange and just have AI micromanage the economy. AI should be able to figure out how much to produce, how to limit waste, who should get what, etc. in a very fair and efficient manner.<p>Who owns the robots though (plus scarce exclusionary inputs), and how are you connected to the part of the trade graph that produces abundance?<p>> If there’s no limit on production, and no need for human labor, then we don’t need to incentivize people to work, or try to bound the amount people consume by the value of what they’ve produced.<p>This is very much a question about who controls the means of production.</p>

<p>The materials in a 60hz transformer I think are the main BOM cost for linears? Relatively, transformers are say 2x cheaper than in 1970 (steel and copper are relatively MORE expensive than they used to be but the manufacturing improved) - but chips are more like 100x or 1000x cheaper. The high frequencies of switchers let you shrink the transformer (less materials) so its a big win.<p>Also the waste heat of linears constrains your design in terms of weight, power density, how big you need to make the enclosure, etc.<p>For reference I looked at what I'd need to buy on AliExpress to power my laptop off the cheapest linear PSU I could find (say 20v 5A), something like: <a href="https://www.aliexpress.com/item/1005003397909174.html" rel="nofollow">https://www.aliexpress.com/item/1005003397909174.html</a> - it weighs 4kg vs 300g for the charger I have. Apparently there ARE audio people who put their NAS on a linear PSU (I did not realise that was a thing!) but I'm going to try to forget I saw that.</p>

<p>Right; most kids won't be very interested unless they're around other people who seem genuinely interested. They key their learning effort off perceived relevance. Perversely, bad school environments can kill interest instead of nurturing it.<p>The very best environments will have other kids who are engaged. It is induction into a <i>culture</i>, with its own language, ways of thinking and values. If you can't find that directly, you have to do your best to create a mini version as a family.<p>You can turn almost anything into a little maths games, card or dice games provide an opportunity for probability puzzles, the environment provides things to estimate and count, you can challenge them on car trips with rates and distances, etc etc etc. How many sides does a circle have?</p>

<p>Feels like an interesting trend where a "solution" for parent anxiety (and to be fair, vastly increased societal expectations around what "care" looks like) is proposed to be electronic surveillance.<p>It's a kid tracker / ankle bracelet in an attractive form factor.<p>I was a kid in the 80s, city fringe, single parent who worked until 5:30. Honestly nobody had any idea where me & my friends were a lot of the time. Totally acceptable in that era.<p>The main worry I have about tech like this is, at what saturation of deployment does the norm shift such that it's irresponsible NOT to electronically track your kids whenever they leave the house?</p>

<p>It is not "multiculturalism" in the way that word would be used in say, Canada.<p>They have quotas to prevent enclaves, they actively manage immigration to keep it about 3/4 Chinese, there are a lot of restrictions on speech and the ways you're allowed to organise.<p>The things Singapore does to manage their ethnic diversity 100% would not fly in the west.</p>

<p>I feel like the shape of the market right now for "home lab" inference is:<p>The sparks are good if your ultimate plan is to spend even more on NVidia hardware in future to run your dev setups at usable speeds. Or, you're developing for a work cluster.<p>If you mainly want to run local models at acceptable speeds portably, buy a mac with lots of RAM. If you’re happy with non-portable / racked, buy 3090s (dense) or mac studios (MoEs). Buy newer cards if you are restricted on power or slots. If you are rich, buy a6000 blackwells.</p>

<p>From the perspective of pre-history, anyone living in a western country is in a post-scarcity society.<p>Practically no one starves. The murder rate is down by crazy numbers. I'm not sure how much of a problem racism was at that time, but you wouldn't have had many chances to meet people from different haplogroups in any case.<p>The abundance created by industrial society is not distributed "evenly" or "fairly" but the baseline shift is insane.</p>

<p>Thanks; I didn't spot that they disabled tools in the harness. Also they don't provide an "out" to allow the models to express uncertainty so the instructions force a guess to be made.<p>As an aside though it's still funny that the two tools WITH search also disagreed.</p>

<p>iOS always had a strong focus on security but if you take the time period say 2005 - 2015 it did not seem like there was much investment in macOS security at Apple. I am talking about stuff like exploit mitigations and relatively low hanging LPEs. Features like (full) ASLR / SIP / kext controls were added well after competitors.</p>

<p>What's your thinking on this? From my perspective Apple security go pretty hard. They have a strong track record of being able to ship architectural mitigations like PACs / MIE / Exclaves first. I guess because Apple control the stack from silicon to userspace.</p>

<p>Structurally the way it works is that the AMA or ALPA or what have you lobby for regulations that just so happen to limit supply, and heavily push back whenever anyone proposes regulations that would loosen it, usually on safety / quality grounds.<p>There are also revolving doors between the regulator and the relevant professional bodies.<p>I'm pro union in cases where employers are a monopsony and workers have few options - it completely makes sense for coal miners in a coal town to form a union to even things out. I just don't think US tech <i>right now</i> meets the conditions for it to make sense, the market is too liquid for employers to capture all the upside.<p>US tech workers have real problems and complaints - PTO, maternity leave, health care to start - but these feel to me more like structural features of the US labour market? It makes more sense to me that these should be subject to national regulation rather than specific advantages for tech workers carved out by a union.</p>

<p>These "unions" in high paying fields behave more like guilds or cartels than worker's unions - they generally restrict supply. Athletes and Hollywood unions are sort of special cases too, IMHO. I don't think it's reasonable to claim that top earners in those fields earn so much because of their unions - they benefit from natural supply restriction of outliers.<p>For unions to be as effective in tech as for say pilots or doctors, you'd have to agree on a way to restrict supply (H1B restrictions, more licensing and credentialling etc) to give the union leverage. You have to control the supply taps and rate limit entry to the field.<p>I think it's hard to say if this would net out better for workers than the current arrangements, which are already the best in the world on nearly every metric.<p>It also seems like there's a timing issue - if tech workers DID successfully unionise enough to withhold a meaningful fraction of labour, the gains might ultimately end up in the market cap of AI companies via substitution.</p>
