  • People in this thread apparently aren’t paranoid enough or have some ridiculously optimistic beliefs about the US and surveillance policing.

    Here’s an article about how the police in my city (New Orleans) worked a secret deal with spy company Palantir to consolidate data from numerous sources to create a crime-prediction system that we’ve been the unwitting beta testers of. https://www.theverge.com/2018/2/27/17054740/palantir-predictive-policing-tool-new-orleans-nopd

    And here’s a page from my own city government bragging about the same: https://nola.gov/next/homeland-security/topics/real-time-crime-center-en/

    I can’t find the story now, but at one time (less than 10 years ago), Palantir and NOPD were working a deal that would require the CCTV feeds from every bar and restaurant in the city to be fed into the “crime control center” which would have instantly made NOLA the most surveilled city on earth. The citizens voted down the bill that would have made it happen, but there was no technical limitation. I’m not convinced they don’t have secret access to them anyway.

    Police can also subpoena camera operators for footage. This happens with Ring doorbells, Amazon is only too happy to hand over footage from the camera on your front door to the police.

    If you are buying cameras for yourself, any video that goes “to the cloud” is now government property. Very few companies have the desire or power to deny their host government’s or their police’s access to the video. If the cloud is in the USA then our spys already have it. Keep your video local or sync it through your own networks.

    If the camera is attached to a business though, you should just assume that government can look through it.



  • All software is political. What a terrible opinion. If you are security minded, don’t rely on any software you don’t control the source of and haven’t fully vetted. Otherwise whoever developes that code has a back door into your system regardless of what opinions they post on Twitter.

    Moreover, people have rights to the code they write. If I decide that my numeric library shouldn’t be used in missile guidance systems I have a right to demand that. I’ll be ignored, and so I think a person then should be expected to escalate.

    Life is political, and there’s no standing neutrally still on a planet rapidly spinning towards revolutionary restructuring.





  • Out past the planets is the heliopause, the final boundary between the solar system and interstellar space. Voyager discovered it, but other probes have confirmed it. The radiation and particles emitted by the sun create a pressurized bubble around it, where plasma (energized particles, mostly hydrogen) is much denser than past the heliopause. Cosmic rays are more prevalent outside it.

    I’ve heard it compared to the empty zone around where a sink faucet first hits, creating a little “wall” of water around it as the splashing water pushes back the standing water.

    “Empty” space is anything but. There’s tons of particles and energy flying though it, just not as dense.


  • Valtonen says that this has made the CPU the weakest link in computing in recent years.

    This is contrary to everything I know as a programmer currently. CPU is fast and excess cores still go underutilized because efficient paralell programming is a capital H Hard problem.

    The weakest link in computing is RAM, which is why CPUs have 3 layers of caches, to try and optimize the most use out of the bottleneck memory BUS. Whole software architectures are modeled around optimizing cache efficiency.

    I’m not sure I understand how just adding a more cores as a coprocesssor (not even a floating-point optimized unit which GPUs already are) will boost performance so much. Unless the thing can magically schedule single-threaded apps as parallel.

    Even then, it feels like market momentum is already behind TPUs and “ai-enhancement” boards as the next required daughter boards after GPUs.




  • I made a static site with Hexo a few years back. I thankfully didn’t make any “Get started with Hexo” posts but I did only really use it for a few months. I think that puts me in the cluster with the “switch from Jekyll to Hugo” people. Now it just sits there, absorbing some money every two years for the “personal website tax”.

    Shame too, I constantly think I need to get back to it. Hexo is nice, popular with Chinese users I think. I don’t recall now why I liked it over Jekyll or Hugo, but I’ve always loved an underdog. Once I got the hang of using it, it was very customizable and fun to work with.



  • I, like most of the millenial lemmings it seems, am not shocked about this. I remember what Dubya said as president, the daily evils. I would have never thought it could get worse and then we got Trump, and I think it all does echoes out from 9/11. If there are future historians, 9/11 is going to be the pivot that this entire century stumbles over, probably leading directly to WW3 any day now.

    But when I see articles like this, (in the Atlantic ofc, always this one or the NYT) my nostrils fill up with the smell of consent being manufactured. Has the shadow council decided that we shall war with the Saudis now? With Russia and China just flat-out taking land now, has the US decided to extend it’s “protection” more directly over a few strategic areas?


  • I really enjoyed this game back when, and replayed it a couple of years ago. Very unique RTS mechanics and engine, I’m excited to see this open sourced!

    Perimeter had several weird gimmicks. Bases must be built on terrain that has been flattened with a terriforming tool (voxel/heighmap manipulation of the landscape is part of the game.) The titular permiter is an energy shield that you can put up around your entire base. There’s also only 3 basic units, but units can be fused together (and separated back out) to make more advanced units on the fly.

    The terraforming-as-war approach is neat and I’ve always been surprised that more games don’t try to incorporate similar mechanics. The multi-units are interesting but to me suffer a similar issue as games with many guns but only one kind of ammo. By the time you’ve decided to switch tactics, you might already be too low on basic units of one type to change into what you need.

    I keep my Obsidian notebooks and several source code repos in syncthing and then have them auto-shared between all my computers and my phone. Its been a great system, all my docs I need are readily available on all my devices with almost no delay and no cloud needed. A little advanced configuration to allow local deletes and I also have all my phone photos backed up this way too.

    When I travel, I use my laptop and phone on a little travel router, so they’re always networked together and syncing files. Definitely saved my butt a few times!
