I doubt it very much that either Russian war on Ukraine or the US attacking Iran happened due do scarcity of resources. Old folks in power want their page in history books.

could you please point to an example? For my project i'm currently animating matplotlib plots and walk through the video later, but rendering times are quite painful.

thanks for the work, this looks amazing. Have you considered trying numba for acceleration? It's great for number crunching.

It's also a form of reconnaissance. In doing these acts they observe how different actors respond and look for potential weak points.

and the goal for this toeing the line is to spark discussion and disagreement between member states. Article 5 credibility is already at it's lowest point after Vance's speech and the new US security strategy, now isn't just the matter of sowing further disagreement.

I believe this is about the perceived switching cost for the masses who, in the US and Europe for example, are predominantly not vegetarian.

walterlw — Wed, 05 Nov 2025 10:57:56 +0000

I believe that Python is as popular and widely used as it is because it's old enough to have an expansive ecosystem of libraries. It's easy enough to implement one in pure Python and possible to optimize it later (Pydantic is a great recent-ish example, switching to a Rust core for 2.0). That same combination of Python + (choose a compiled language) makes it quite difficult for any new language to tap into the main strength of Python.

wouldn't it be enough for the underlying user data to be stored in a well-documented and widely supported format? I don't care if Obsidian, Logseq or similar are open or closed source if my data is just a folder of markdown and jpeg/pngs.

I'd like to remind you that Russia is not the USSR. Surely the technology has significantly improved since, but some capabilities are definitely lost. One example is them not being able to build more strategic bombers.

Very impressive work. Was very saddened to see how Ukrainian Kyiv and Kharkiv stations were excluded. We have deep stations (like Arsenal'na at 105m that connects directly to the above-ground Dnipro station on a river bank), we have both Soviet-made and new stations. Also now they are doubly essential being used for both transportation and shelter during air raids by millions.

highly recommend that as well. Disabling history greatly reduced my time spent in the app. UnTrap plugin for Safari helps as well. Can't say that I feel like I spend a reasonable amount of time on the platform still, but now it's mostly me having an urge to distract myself, opening the website and finding the videos I have seen already then closing the tab.

would absolutely love this for a personal note-taking project, but having image support and some sort of auto-completion for commands, lists, tags etc is crucial for something i'd use every day on desktop and mobile. Still love seeing more options for different purposes.

walterlw — Tue, 05 Aug 2025 06:19:18 +0000

I've used tmux like that a bunch before discovering process-compose [1]. Still use tmux a lot with remote connections and booting up a few scripts in parallel is still easier with it, but for longer-serving setups p-c has helped a lot

Biden took the approach of keeping 10 pairs of gloves on when dealing with Russia. Don't help too little not to make it too easy for the russians, don't help to much to avoid escalation.

walterlw — Sun, 22 Jun 2025 08:25:10 +0000

Now every country that has the capacity to get a strategic deterrent will race to get one. So much for Biden's escalation management. Too bad Trump likes Russia so much he does everything not to step on their toes. With a heftier backing from the US the Russo-Ukrainian war would be over by now.

Very true and joining in on the thanks. Did you find a way to download it as a pdf though? I believe it is essential to be able to add notes and references when reading any learning material.

walterlw — Mon, 16 Jun 2025 10:01:17 +0000

there are still a lot of problems to be solved using "classical" computer vision, especially in systems where you don't have easy access to GPU acceleration. I am a practitioner doing Simultaneous localization and mapping on compute-restricted platforms, so definitely going to read the Structure from Motion chapter.
