<p>Fantastic piece of lore. Fascinating to read the journey. But also hearing some of the names here (Tavis Ormandy is famous for his role on Project Zero, for instance) and knowing that even top engineers can bomb interviews for making poor choices.<p>Nothing useful to add except that I Like these blog posts from someone who actually did a bunch of things. Nice round-up of the past.</p>

<p>The event itself is really bad and condemnable, but when threads like this show up they are usually a good thing because people rapidly demonstrate high coupling of tribal affiliation with viewpoint. This causes a lot of them to advertise through unhinged posts which is a good raw test for what they are like to communicate with. I usually go through and killfile a bunch of these commenters. Essentially, you want your bad participants to be easily visible to be so. I don't want them to be subtly sneaking their stuff in normal threads. I want to go look at one place and see all of the people I don't want to listen to.<p>Therefore, here's a feature request: allow per-user killfiles. I currently have this through a Chrome extension but I'd love it to be native so that I don't have to use my own iOS app and so on.</p>

<p>The core density is really low. You can run a 96 core Epyc from the previous generation at 700 W and that’s a lot of compute. It makes sense for a home server (and I have an old Mac playing that role at home) but otherwise I don’t think it makes sense unless you’re taking off the display and racking them super tight.<p>Even then, you’re probably better off with Cloudflare tunnel and using it as a home server.</p>

<p>I was avoiding getting into the specifics because rather than tea-leaf-reading a picture one can simply look at the numbers themselves and they cannot support anything but that the one year period immediately following the lockdowns was much lower than the surrounding years.<p>And I think it was great you shared the news article! For many others, analyses one does oneself are less believable. I prefer doing it myself to convince myself but I wouldn’t expect it to convince others. Here I did it because I wanted to know what the fact is and I always have trouble with picking change points on a bar graph without all the ticks marked.<p>I put it at this level because it feels supplemental to your link not because it’s a debunking of your comment or whatever though perhaps <a href="https://news.ycombinator.com/item?id=47690707">https://news.ycombinator.com/item?id=47690707</a> is the best place to do it.</p>

<p>What I do is have a quick command that spins up a worktree on a repo with my ghostty splits as I like them and the tmux named the worktree. I then tell the Claude code about the tmux when it needs to look. It’s pretty good at natively handling the tmux interactions.<p>Ideally Ghostty would offer primitives to launch splits but c’est la vie. Apple automation it is.</p>

<p>I actually really enjoy getting this sequence of emails but I use Gmail’s auto categorization so it just goes in the “Updates” folder and gets auto-forwarded to my claw-like so it’s not super interrupty. I prefer to have the full trace on my side rather than on the provider side because their site might go down and so on.<p>I can see why people get annoyed. It’s just the alternative that I really dislike.<p>This way I can do all analysis on my own side or search for status on my side. I prefer to own the data and have it pushed in a timely manner.</p>

<p>It was a not-particularly-amusing joke that people honk because doing so helps the light change. It doesn’t, of course, but I used to work at a building at the intersection of Bush and Sansome (I think), the Standard Oil Building, and every day at 5 PM the honking would put Bombay to shame.</p>

<p>Ah, I see. It’s just straightforward protectionism like dockworkers opposing automation and so on. That I do comprehend, in fact.<p>I write software too and I may no longer be able to just do it in the old way. Pretty scary world but also exciting. I can’t imagine trying to restrict LLM software writers on that basis but I can comprehend it as simply self-interest.<p>Fair enough.</p>

<p>If I'm being honest, I've never related to that notion of remuneration and credit being the primary reason to write something. I don't claim to be some great writer or anything, but I do have a blog I write quite often on (though I'm traveling in my wife's Taiwan now and haven't updated it in a while). But for me, I write because it feels good to do so. Sometimes there's a group utility in things like I edit a Google Maps listing to be correct even though "a faceless corporation is going to hoover up my work and profit off it without paying me for my work" and I might pick up a Lime bike someone's dropped into the sidewalk even though "a faceless corporation is externalizing the work of organizing the proper storage of their property on public land without paying the workers" or so on.<p>I just think it's nice to contribute to the human commons and it's fine if some subset of my fellow organism uses it in whatever way. Realistically, the fact that Brewster Kahle is paid whatever few hundred thousand he's paid for managing a non-profit that only exists because it aggregates other people's work isn't a problem for me. Or that Larry Page and Sergey Brin became ultra-rich around providing a search interface into other people's work. Or that Sam Altman and Dario Amodei did the same through a different interface.<p>This particular notion doesn't seem to be a post-AI trend. It seems to have happened prior to the big GPTs coming out where people started doing a lot of this accounting for contribution stuff. One day it'll be interesting to read why it started happening because I don't recall it from the past. Perhaps I just wasn't super plugged in to the communities that were complaining about Red Hat, Inc.<p>It's not that I don't understand if I sold my Subaru to a guy who immediately managed to sell it to another guy for a million times the money. I get that. I'd feel cheated. But if I contributed a little to it, like I did so Google would have a site to list for certain keywords so that they could show ads next to it in their search results, I just find it so hard to be like "That's my money you're using. Pay me!".</p>

<p>The data is open, and so we don't have to do the visual reasoning off an imperfect graph. SF Chronicle has done a pretty rare (but I think good journalistic practice) of specifying the source of the data: <a href="https://data.sfgov.org/Public-Safety/Police-Department-Incident-Reports-2018-to-Present/wg3w-h783/about_data" rel="nofollow">https://data.sfgov.org/Public-Safety/Police-Department-Incid...</a><p>First to match the graph you make sure you pick 'Larceny - From Vehicle' only (there are some others one might argue matter) and ensure you're only counting incidents once (many rows reference the same incident). That lets us recreate the original graph.<p>When looking at many things I like to look at seasonal effects just to see, and it doesn't look like they are significant here (but you can see the Mar 2020 drop to the next year quite easily which I like): <a href="https://wiki.roshangeorge.dev/w/images/2/2e/SFPD_Vehicle_Break-Ins_Reports_Heatmap_2018_to_Mar_2026_Incomplete.png" rel="nofollow">https://wiki.roshangeorge.dev/w/images/2/2e/SFPD_Vehicle_Bre...</a><p>I also tried overlaying various line charts but that's useless for visually identifying the break.<p>One thing I thought would be fun is to run a changepoint algorithm blindly <a href="https://wiki.roshangeorge.dev/w/File:SFPD_Vehicle_Break-Ins_Changepoint_2018_to_Mar_2026_Incomplete.png" rel="nofollow">https://wiki.roshangeorge.dev/w/File:SFPD_Vehicle_Break-Ins_...</a><p>I like PELT because it appeals to my sensibilities (you don't say ahead of time how many changepoints you want to find - you set an energy/cost param and let it roll) and it finds that one changepoint. You can have some fun with the other algos and changing the amount of breakpoints or changing the PELT cost function. And then you can have even more fun by excluding 2020 or excluding Mar 2020 onwards or replacing it by estimates from the previous years (quite suspect considering what we're trying to do but hey we're having fun - a bunch of algos all flag Nov 2023 as some moment of truth)<p>Anyway, anyone curious should download the data. It's pretty straightforward to use and if I goofed up with off-by-one or whatever, you can go see for yourself.</p>

<p>It's just cultural. If there's a cultural expectation of the ring/honk it's not rude. e.g. in India people will honk as a form of active group flock behaviour but foreigners will interpret it as everyone saying "get out of my way"; but in some European countries I have seen that people use the bell (much less noisy than the typical Indian street) and it's got the same meaning. In Hawaii, if you ever honk at someone, you're going to have a fight on your hands. In San Francisco, if you honk at someone and you're on Bush Street it means you're trying to help the traffic light change (it's a team effort) but anywhere else you get anything from a gun drawn, to a brake check, to a wave in apology for missing the light by being on the phone.<p>Overall, cultural expectations are everything here so it's best to just "when in Rome, do as Romans do".</p>

<p>No, I had access to free tirzepatide. I chose retatrutide because early results seemed promising and safe and since I was going to run a short-term self-trial I wanted the most effective peptide.</p>

<p>I used retatrutide for weight loss and went from 199.3 lbs to just under 175 lbs. I kept daily notes through the process. Here's a quick AI one-paragraph summary if you're curious: <a href="https://pastebin.com/XACNYKvs" rel="nofollow">https://pastebin.com/XACNYKvs</a><p>Overall I'm quite pleased with the effects and many of the properties of this treatment that people dislike are actually properties I was looking for. Essentially, for pharmacological interventions I want impermanent effects with a clear dose-response relationship and ideally minimal or no adaptation.<p>So the fact that people gain weight when they go off it and then lose weight again when they go on it was good. That meant it's fairly easily undoable. The fact that the more you take the more you lose also was pretty good to know though for the majority of the time I took less than any tested dose (and the effects were quite strong on those).<p>I did experience quite a bit of adaptation so I needed to up the dose until I was in the range tested by the end. I've been off it for a month now and been pretty much flat, but we've been traveling since I stopped and so a lot has changed (no more lifting, lots more eating, lots more walking).<p>Rough cost for the retatrutide is $1.25/mg.</p>

<p>Absolute nostalgia fever. About a month ago, I dug up an old desktop in the corner, took the drives out and gave away the machine. It felt like putting a racehorse to pasture: i7-4790k, 1080 Ti. It was my dream machine when I got it. Dual-boot (as we did back in the old days when Proton wasn't here) to Ubuntu, then Elementary, then Arch. By the time I gave it away it wasn't worth the power cost.<p>And that brought to mind my older dream machine, an 8800 GT from generations past, before which we made do with a Via Unichrome that worked sufficiently enough on the OpenChrome driver that I could edit open software (Freespace only needed a few constants changed) so it would render (though some of the image was smeared and so on I could play!).</p>

<p>That's true, but I've noticed that AI text content is very prompter-focused. Someone once described them as dreams - more meaningful to the dreamer than to anyone who has to listen to them narrated. Perhaps it's just inherent to the fact that textual content is rarely viral at that length. It's a base-rate issue.</p>
