<p>I found success in starting our from an LLM positive poster and fanning out from their follows and building a follower graph. From there I fetch a few hundred of their posts and used an LLM to classify the posts as negative, mixed, or positive. I used this to winnow a set of follows. For now I just poll and generate a timeline HTML. This has yielded decent results.<p>But the problem with all of these Twitter clones is the political schism of Musk's acquisition has largely polarized the offshoots. You aren't just on alt-Twitter, you're on a specific polarized chunk of it.</p>

<p>I'm not sure of your background, but FWIW everyone in my PhD program in my elite CS program had varying levels of anguish and angst when realizing that their efforts were mostly suited for "coloring in the blanks." The PhD Grind [1] felt like a poignant capture of those feelings.<p>[1]: <a href="https://dokumen.pub/the-phd-grind-a-phd-student-memoir-3.html" rel="nofollow">https://dokumen.pub/the-phd-grind-a-phd-student-memoir-3.htm...</a></p>

<p>FWIW as someone in silicon valley, this really isn't the silicon valley mindset. HN represents a sort of messy combination of many different tech tribes, but I will say its depiction of silicon valley is largely that of someone who reads too much tabloid coverage of it. It's very much the feeling one gets about silicon valley by reading Techcrunch articles without actually being here.<p>I actually think it's a bit dangerous to try and understand SV from HN comments, in the same way that trying to learn about an event by watching a fictional adaptation of it can often confuse more than educate. The goal of the comments here aren't for SV to chat anymore and it hasn't been for a very long time, for better or for worse.<p>Twitter is closer to what you'll get among founder and hype circles in silicon valley, but even that isn't a good pulse of what engineers here actually think. The public web is just too adversarial a place for most folks to want to hang out anymore and silicon valley has been so deeply politicized in the news that a lot of people just don't want to air their opinions in public anymore. My suggestion is to save up some money and just come here and visit for a week or two, go to events, rant to a few graybeards, that kind of thing. You'll get a much more authentic look.</p>

<p>> With native frameworks, you often get very close to "feel right" without much effort.<p>I've only seen this sentiment on nerd forums but never among my less technical friends, so I'm a bit reluctant to accept this wisdom honestly. That said, if you're just building something for a technical crowd you'll probably make them much happier if you make your implementation use native widgets and take up much less memory and redraw faster at the expense of a slightly jankier UX. Though, this is probably why IRC clients all feel janky lol.<p>For example a lot of my less technical friends/family really like the visual design of Spotify even though it conflicts with a lot of design language on MacOS, Windows, and Android.</p>

<p>Yeah this was one of the stupidest comment sections I've read on this site in recent memory, and these days the commentary here is definitely not high-brow. Most of the comments were just "I don't like rationalists so they're stupid." I think there's plenty of very obvious, fertile critique one can make against rationalists but there's so little of that here in this comments section that it makes me quite sad.</p>

<p>I'm not sure how much that is age correlation. Suburbs are older and usually have more parents, so they're more likely to volunteer in clubs and organizations. Even in my urban area the most frequently volunteered at organization is the PTA and most of the soup kitchens and senior centers have volunteers in their late 30s to early-50s.<p>Community engagement isn't also quite the same thing as friend groups. This is making me interested in doing a similar analysis.</p>

<p>Heh there is lots of minutiae, but I'd argue that the NMSL is actually a very big part of transport history in the US and is absolutely something that people should read about. I actually think covering it should be part of basic US civics but :shrug: doubt that's going to happen.</p>

<p>My understanding is that the 85 pct rule has fallen out of favor outside of highways (where the mode mix is 100% high power automobiles.) I know for my municipality and my state, we set speeds in denser areas based primarily on the mode mix and in less dense areas a balance between vehicle volumes, congestion in surrounding areas, and mode mix.</p>

<p>If folks are actually interested in how speed limits are set in American cities, I'd encourage them to read about the process in their municipality rather than absorbing information from message board conspiracy posts. In practice, there are indeed several competing pressures that dictate speed limits.<p>One source of pressure to keep speeds high is that if municipalities can classify a street as a collector or arterial, they can get federal aid for projects related to the road. As such cities will often want to bring a local road up to collector or arterial status so that they can get higher federal funding for it. (Collectors and arterials usually are larger streets with higher speed limits, though the biggest gray zone is between collectors and local roads and often the biggest difference is indeed the speed limit.) Urban planning discourse about "stroads" in the US is largely a story of local roads that have eventually been classified as collectors or arterials so retain the residential or commercial density of a slower road but are expected to have the speeds and vehicle volumes of faster roads.<p>(FWIW I first saw this on city-data in the early 2000s and vaguely heard my parents' generation say similar things to this comment, but when I actually started listening and attending local meetings I realize that it's mostly an urban legend that gets repeated to each other.)</p>

<p>This link claims this is for highways. Does TxDOT have a wider criteria for "highway" than the standard FHWA criteria? Under FHWA I would presume that school roads would be found on local or collector roads, not highways, but I'm not familiar with the streets mix nor the grant landscape of Texas cities.</p>

<p>This was always a big problem even in the pre-LLM days. The difference was that you only needed to be better than your competitors at solving the customers' problems. There's a reason everyone gripes about the software that they use and it's because the software is built to satisfy a very broad customer base, broad enough to justify the engineering time put into it. Now you're competing against tens (maybe hundreds) of other firms all building for the same competitors so there's a lot of pressure to get the shape exactly right.<p>There's a reason the product-minded highly-technical engineer was always highly sought out.</p>

<p>A bit thin on details, but seems like their solution presumes being always online, so rather than replicating a merkle tree it lets checkouts request source on demand. Is this "best practice" for large monorepos?</p>

<p>ActivityPub is essentially this in "modern" times with "modern" sensibilities (e.g. accounting for low power mobile devices that are going to hold open only a single connection and query for posts.) You can pretty trivially killfile whatever you'd like too. I vibecoded a super basic AP "client" that just speaks AP vocabulary to fetch posts from users I have in a JSON file.</p>

<p>Science has always had an empirical component separate from its theoretical one. For a long time in human history, science was mostly empirical. The periodic table is a great example of mostly empirical observation organized into a pattern. I think the science of the 20th century was the "triumph of theory" so many of us have forgotten what a more empirically driven STEM world is like.</p>

<p>> Sure, there's the obvious "I enjoy the mechanics of programming" component that's gone but then there's also this general feeling that is hard to shake which feels a little deeper. I've wondered about it. Is it all the layoffs? The suddenly shaky economics for a lot of our companies? The uncertainty of the career's future in general?<p>Internet town squares have polarized. Not just by capital P politics, but just according to the poles that inhabit them. The highly energized maximalists and doomers spend all of their time posting online about it, not really caring about whether the community or even reality conforms with their thoughts. The rest of us roll our eyes and leave the town squares. We laugh at them in our group chats, sneer at them at our parties, but we don't talk in the town squares about the absurdity anymore.<p>I don't really know what to do about this. When the SaaS boom was happening in the late 2000s/early 2010s, there was a tranche of cautiously optimistic and cautiously pessimistic bloggers, along with the highly motivated zealots. The middle is hollowed out now.</p>

<p>I am quite pro AI for various reasons, but for this reason I just don't see low effort AI art really taking off beyond memes, corporate promotional material, and porn. The value of art is the humanity behind it. It's the reason abstract modern painting continues to be valued despite many folks finding its absolute skill level to be lower than, say, the impressionists or modernists of yore.</p>
