This is just a long-winded article by someone who thinks they've come across a deep, crucial insight.<p>I witnessed a bank foreclosure stemming from large, unpaid loans to a lumber mill. The bank absolutely didn't want to take possession of the operation, but had no choice when the founder decided to call it a day.<p>The bank had no idea what to do with finished lumber sitting in the drying ovens, let alone the entirety of mill infrastructure itself. After struggling to find a buyer, they hired the founder as a consultant to handle liquidation. The same would happen with a repossessed datacentre.</p>

<p>There is no substance. It's navel-gazing dribble.<p>The "about" section of the website is equally vacuous:<p><pre><code>    SmolNero is a philosophical startup rooted
    in first-principles thinking.

    We explore how humans relate to technology—
    how we speak to it, depend on it, thank it,
    and sometimes forget it’s there at all.
    
    We don’t claim expertise. We see ourselves 
    as translators—working at the crossroads of
    emotion and programming, curiosity and care

<p>I think you are taking an excessive interpretation of what was suggested.<p>Let's level-set on the issue: Of late, GH has suffered a continuous stream of noteworthy outages. It is hypothesized the underlying cause of the instability has been the dramatic rise in submissions from coding agents ("AI"). The open question is how (or whether) GH can get load at a manageable level, with the proposal being, 'don't immediately allocate build/compute resources against any and all submissions.'<p>I don't see why that is equivalent to rampant disenfranchisement in the open source community. I believe what people have in mind is closer to, "don't immediately trigger an expensive build process as soon as someone submits a pull request."</p>

<p>I think Clearmotion has a very interesting technology and product (ride stabilization), but let's paint a full picture here: the company was founded in 2009, took on $370 million in funding, and only recently landed large contracts (a $1 billion dollar deal in 2023 with Chinese auto manufacturer, Nio).<p>I'm sure they were in a constant struggle for survival and had to "move fast" to stay afloat, but their technology is more than a decade in the making.</p>

<p>I worked on deep sub-micron, full custom mixed-signal integrated circuits for more than a decade, and I can't pass the first level.<p>> Wire an NMOS transistor so that when In is 1, the output is pulled to ground (0). When In is 0, the output should be unconnected (Z).<p>Certainly:<p>(a) The nMOS has 3 connections: its drain is only connected to the output (no +Vdd supply), it's source is tied to ground, it's gate is tied to the signal input<p>(b) When the gate (input) is driven high, the nMOS transistor turns "on," connecting the output to the source (which is grounded). This acts as a "pull-down network"<p>(c) When the gate is driven low, the nMOS turns "off," leaving no connection to the output. This is equivalent to a "high-impedance" / "unconnected" / "Z" output<p>Fails 1/2 tests<p>(Edit) - I thought the light grey, thick line on the background grid was a wire from "input" to the transistor's gate. It is not. You need to explicitly add a wire from "input" to gate :\</p>

<p>They certainly have, but the general idea is to first use stealth jets to bomb defensive systems (including radar observability) to conquer the skies, and then you can fly around somewhat freely. While SAM technology has improved, so have America's observability and stealth bombing capabilities. It will be interesting to learn the context and sequence of events which led to an F-15 being shot down by enemy fire.<p>(In 1991, the United States relied on the F-117 Nighthawk to penetrate Baghdad and launch salvos against radar and SAM sites. Simultaneously, Tomahawk cruise missiles were fired against similar communication and defense sites. In this war with Iran, the F-35 and B-2 have been used for stealth missions).</p>

<p>During the entire gulf war (Iraq, 1990-91), only two F-15s were shot down via surface-to-air engagement. At the time, Baghdad was known to have the highest density of SAM protection out of any city in the world.<p>An F-15 being shot down in Iran after weeks of strategic bombing of their anti-air defense systems is not a good sign.</p>

<p>> The Claude C Compiler illustrates the other side: it optimizes for<p>> passing tests, not for correctness. It hard-codes values to satisfy<p>> the test suite. It will not generalize.<p>This is one of the pain points I am suffering at work: workers ask coding agents to generate some code, and then to generate test coverage for the code. The LLM happily churns out unit tests which are simply reinforcing the existing behaviour of the code. At no point does anyone stop and ask whether the generated code implements the desired functional behaviour for the system ("business logic").<p>The icing on the cake is that LLMs are producing so much code that humans are just rubber stamping all of it. Off to merge and build it goes.<p>I have no constructive recommendations; I feel the industry will keep their foot on the pedal until something catastrophic happens.</p>

<p>> Whenever a new layer of abstraction is added<p>LLMs aren't a "layer of abstraction."<p>99% of people writing in assembly don't have to drop down into manual cobbling of machine code. People who write in C rarely drop into assembly. Java developers typically treat the JVM as "the computer." In the OSI network stack, developers writing at level 7 (application layer) almost never drop to level 5 (session layer), and virtually no one even bothers to understand the magic at layers 1 & 2. These all represent successful, effective abstractions for developers.<p>In contrast, unless you believe 99% of "software development" is about to be replaced with "vibe coding", it's off the mark to describe LLMs as a new layer of abstraction.</p>
