<p>Ranking software engineers is famously hard. What does "top 40%" even mean ? Skills/Experiences/Productivity in that sector are not some Gaussian Distribution of trivially-measurable output. But even if measurable, they're not gaussian distributed for sure. My mum won't make a software engineer anyone would hire no matter how much AI you gave her to assist. If you fire all your developer staff other than the "10x-ers" who with AI assistance have gamed your metrics^W^W^Wboosted their skills to become 100x-ers then you rip the floor from your company; noone to question or review the golden code, 100% trust into something you barely understand and cannot question, and you pay for it. Maybe little now while you're being fixed on. Once AI operators try to get their "money back", there's the sucking sound of a few trillion moving from AI users to ... somewhere. Not your share price, though.<p>AI is a great tool. Including for software engineers to train with and learn new skills, find new application areas, build new products. It's not doing it justice to call it "autocomplete on steroids".
If these five "100x-ers" leave a year in to found their own company, not the least because they've become aware of the size of the mess, then good luck swinging your product strategy to "hey AI, sell this product I'm going to tell you to build".</p>

<p>These relative figures mean nothing. Your usage of one specific ultra-new model went from one hour a month to seven? congrats to the 600% increase. Your use of a widespread common model went from 1M tokens to 7M tokens ? Also a 600% increase. Your spend on AI from 1M/month to 84M/year ? ditto.<p>Other than the latter, I'd read all this as meaningless. Am I wrong?</p>

<p>"velocity" is not "frequency"; someone throwing semi-finished products at the wall to see what sticks surely has frequent product launches. But even if these ship fast from inception to launch, this scattergun approach does not scale to provide product maintenance or support. It's a productivity smokescreen for lack of a product strategy, and claiming AI will substitute for support/maintenance fits straight in with that. Anything but coherent strategy, that. Maybe here's an unexplored AI opportunity.</p>

<p>German 50 Trillion (Marks) _stamps_ from 1923 are (literally) a-dime-a-dozen because postal services had a giant amount of them printed for issue in fall-1923 - just to have the whole lot rendered obsolete by the November currency reform. Unstamped/new they're not worth the paper they're printed on. Verifiably used / franked actually on a postal package they are much rarer. Fortune reversal - the worthless item becoming the collectible...</p>

<p>xor'ing the elements of lists together also allows a test of "unordered equality" because 1^2^3^4^5 == (xor of any permutation of [1,2,3,4,5]).<p>Yes there are false positives, and the false negative of all-zero/all-equal, but the test can be useful in a "bloom filter" type case.<p>Have used it in dynamic firewalling rules ... one can do something pretty close to a JA3/JA4 TLS fingerprint in eBPF with that (to match the cipher lists).</p>

<p>> "... handwavy crap ..."<p>handwavy argument. Yes, in the (sub)tropics the argument is even stronger pro-PV, not the least because it'll give you the opposite of heating - aircon - for free right when you need it. And considering summer heatwaves as have been seen the last few years "way north", that benefit will extend that way even if you wouldn't bother considering letting it "assist", if not fully replace, your heating. That said though, for 50° polewards and above, if you wanted to use PV in winter orient the panels vertically. If you can clad your too floor with shiplap larch so you can with PV panels. Given the price of timber ... there's a plan.<p>(only saying handwaving goes both ways)</p>

<p>Definitely not a usecase for Starlink.<p>For the microseconds-chasers, there's microwave relay links, say between Chicago and New York (ref e.g. <a href="https://bullseye.ac/blog/economics/inside-the-world-of-high-frequency-trading-infrastructure/" rel="nofollow">https://bullseye.ac/blog/economics/inside-the-world-of-high-...</a>). Sending a signal up a few hundred km and down again a few hundred km adds way too much latency, and signal-hopping between fast-moving satellites adds way too much jitter for "such applications".</p>

<p>Air pollution (from smog) in India is already at a "seasonally deadly" level. If you haven't been to India during late autumn, it's hard to imagine how bad it is. Your eyes burn and every breath stings, you literally taste the acrid smog all the time.<p>India is working hard to get that down. It's a much more tangible and immediate problem there than the thought some parts of the country may become so hot as to be unliveable. Addressing thst, in India, is a side effect / a benefit of cleaning up the air, as much as energy autarky via Solar PV has the benefit of becoming independent of oil imports.
India has coal. Lots of it. It's cheap to them. It doesn't particularly want to use more of it because of the associated air pollution and also because cooling water for thermal power plants competes with drinking water for people in some places.<p>Personally I think India is rather pragmatic here. Battery banks for scooters in the cities? tick. Buildout of PV? tick. Electric car charging stations? tick. Replacing wood, coal and other dirty cooking fuel by gas? Also tick. India just doesn't bother fighting some internal culture wars about how great fossil fuels or renewables are. They just move ahead more or less silently.</p>

<p>Sometimes, not to do something can be the right (morally, technically, economically, ...) thing to do.<p>You don't always need to present the other cheek to do right. Neither do you always need to retaliate.<p>Nord Stream finally made it clear to Germany that "convenience" isn't a
durable energy market strategy.<p>It's not correct though that Germany has done "nothing". The suspects are pursued by Germany, <a href="https://www.dw.com/en/nord-stream-poland-blocks-extradition-of-suspect-to-germany/a-74395861" rel="nofollow">https://www.dw.com/en/nord-stream-poland-blocks-extradition-...</a> so there's that.<p>If you mean though whether there's a will in Germany (nevermind a commitment or funding) to rebuild Nordstream ... you're right, nothing has happened</p>

<p>Except funding is not everything that's needed for long term projects. There are other resources - workforce, supply chain integrity, legal entitlements and approvals, etc, that are all contributing to "plannable delivery" of long-term projects. And quite a few of these are very much subject to the vagaries of democracy.<p>Unless, of course, you assume (the ideal to be) an entirely anarchist business environment where whoever-with-resources can do whatever. Democracy, though, is not that.</p>

<p>Impossible to raid ?<p>It's definitely much easier and much much cheaper to send a single rocket there blowing the assembled rather large target into still sizeable chucks of orbital debris than it is to deploy and assemble the thing there in the first place. And there are a few terrestrial actors rather capable of this. More than there are who could make it happen under whatever optimistic assumptions anyway.<p>In itself, a structure of this size in orbit is an efficient catcher of micrometeorites and orbital debris. Over "non-eternal" timeframes you don't even need a bad actor with good rockets.<p>Nevermind that in such a case, the eventual fate of these sizeable chunks of orbital debris is to become rods of god ... just without particular steerability.<p>It'd be a sight.</p>

<p>Fighting wars (more than one, in fact) to force a country into permitting unrestricted sale of opioids has historical precedent of course. The victim then was China, which tried to enforce their laws on drugs ... to the dislike of English Businessmen with enough pocket money to buy the army.<p>I for one would prefer to buy wine in a Utah grocery store. Or maybe even just a NYC supermarket. Even if it's wine from Texas, though I know that really stretches the meaning of "wine".

<p>on the m68k, the "cisc-y-ness" is in the many many addressing modes, whereas x86 in that particular aspect of the architecture has always been rather "risc-y" (read: rather limited compared to other CISC architectures, including m68k).<p>The core instruction set of the m68k, as far as ALU/FPU is concerned, is simple enough.

<p>A mandate for government orgs including the military to exclusively use "all domestic" suppliers is laudable but also subject to graft and corruption - companies need to compete to get into the "in" club and admittance will be "gated" by favouritism, political alliance, and whatever grease needed to get you into that club. And once in, you're always tempted to collude ... partition the pie amongst the "competition" while petitioning the government to grow the pie ...<p>Yes, you _can_ try to regulate your way out of that. It'll result in a giant thicket of rulebooks, laws, procedures and processes. Exactly what a "slim" state would not want to see ...<p>(I am not sure there is a perfect way out; "extremely strong" gating criteria though tend to always favour the incumbents, and a prescription of "100% domestic all the way through" is a strong gating criterion if I've ever seen one)</p>
