New ask Hacker News story: Using games/cards to learn new skills
Using games/cards to learn new skills
4 by dominikz | 0 comments on Hacker News.
I wear two hats: - I am making my living being a programmer - as a hobby I rock climb quite a lot (including ice climbing) Story 1 When I started going into avalanche terrain, I quickly realized that I need to get some professional training before something happens. I went to a 2 day course. The lecture for 8 hours in a classroom, even though was done by a really good professional, was hard to understand. Especially when the lecturer introduced something called 'professional method of assesing avalanche risk'. Nobody understood. But at the evening, we went to the bar, ordered a few beers and the lecturer pulled out something called 'Snow Safety Cards' (https://ift.tt/lvTUjCF). And even though we were getting more drunk with each beer, we started to understand that method. Story 2 I joined a new IT project. One of the veterans in our team convinced the founder that it would be great to integrate the team that just grew x3 and meet at a company 'Christmas Party'. We had an official dinner, and then we went to the pub. I pulled out these cards after one round (or two): https://ift.tt/RpSJL5o. We started playing. To my surprise, none of the 15+ programmers knew what is a unix pipeline! Even the veteran. But people started learning it on the go. I don't have to tell you that I wasn't the one winning the game (probably because it is not balanced and it wasn't created with that in mind - mostly to teach kids). It was so interesting to see that it was the same story as with avalanche cards. People had no idea what the subject is, they learned easily on the go even with their frontal cortex numbed. Even though these happened a few years back, I still keep thinking. What is the phenomenon of games that help you go into a pretty abstract/technical field, even when you are in the no-teaching mode? It kind of makes me think that the scientists that study dolphins say that they play 50% of the time, opposed to humans. I wonder if anyone tried to make a dolphin drunk and study how well they acquire knowledge whilst playing.

Show HN: Running BitNet b1.58 inside DRAM by breaking DDR4 timing rules
4 by pcdeni | 0 comments on Hacker News.
I have been working on running BitNet b1.58 inside DRAM by intentionally breaking DDR4 timing rules. Also made a visual explainer: https://pcdeni.github.io/CaSA/explainer/ This is tested and works inside commercial off the shelf memory with custom memory controller in the FPGA. The underlying effect is well characterized in academic papers (cmu safari, simra, dram bender, etc). In the process of getting this to work I also made previously undocumented discovery about DDR behaviour: https://pcdeni.github.io/CaSA/explainer/xor-spread.html Overall it is a bit slow, since data (in full rows) needs to be moved even when what is actually needed is only the count of the '1' bits (popcount). To make it competitive memory die changes would be needed, but not as drastic as merging compute and memory into one silicon. This would then avoid the memory wall issue the industry is currently facing.

Show HN: Open-source private home security camera system (end-to-end encryption)
4 by arrdalan | 0 comments on Hacker News.
Hey everyone, I'm back with some exciting updates. I previously introduced an open source private home security camera in 2024, which uses OpenMLS for end-to-end encryption. It was called Privastead then and it's now renamed to Secluso. John Kaczman found my project from here and has been working on it with me over the last year and half. We've made a lot of improvements to the software, which we would like to share with you: - You can now set this up on your Raspberry Pi in less than 5 minutes with no technical expertise using our easy-to-use GUI deploy tool. We've put together a comprehensive build-your-own guide that walks you through the required steps (you can find a link at the top of the repository README). - We use a customized, minimal OS based on the Yocto project for the camera. - Every part of our stack except for the iOS app has reproducible builds. This includes our Android app, camera/server binaries, deploy tool, and the aforementioned OS. - We've re-designed our mobile app, which is now on the iOS App Store and Google Play store. - We now support UnifiedPush for more privacy-preserving push notifications. Looking forward to seeing what you all think!

Ask HN: What to learn and do, that makes me least affected by AI in STEM?

I could be wrong with what I say here. It's just the situation made me feel so. Looks like AI learnt almost everything there is in the internet and textbooks today. I lost hope of learning anything new out there to make a reasonable difference and impact. Choose any topic AI knows. Its interpretation is far better than what I can come up with by myself. I feel robbed of my intellectual freedom to express and be accepted by others as others depend on AI for everything. I recently started studying physics fundamentals to find solace. These fundamentals cannot be found through AI. No LLM can precisely measure and compare, but instead only predict. But this is mostly an intellectual exercise. I can't do a living from it. I am a software engineer with average skills. I get paid reasonably okay as it helps me survive. Nothing more than that. But AI can make my world topple any time soon. What should I look into as alternatives , even if it's less lucrative software compensation, so that I find AI can't over power me?

It's a clone of 7 Little Words, but with topics from computer science and programming. No sign-up, no app install, no tracking. It's a PWA and works offline, also as a home screen app. Tech: js, no libs, Canvas API, Web Audio, AI-aided but not vibe coded, puzzles curated by hand.

Show HN: ReTab – a Cmd+Tab-style switcher for Safari tabs
3 by hyouuu | 0 comments on Hacker News.
Hey HN, if you do use Safari, try my little ReTab extension. It makes jumping back and forth between tabs way smoother and honestly improves my productivity & enjoyment a ton. Tap Cmd+E to jump back & forth between your last visited tabs Hold Cmd+E to show a list of your tab history to select (just like Cmd+Tab on macOS) Tab history is tracked per-window so cycling stays scoped to the window with focus. No analytics, no remote calls, nothing leaves the Mac — a single Safari Web Extension on MV3 spec + small Swift container app. 22s demo: https://youtu.be/oysvE06Ys-0 Any feedback or ideas are welcome!
