Yeah - big fan of the FM / FM2n (I've also got the latter) The FM3a always really appealed, but the more I think about it the less it appeals. Although it's a mechanical shutter, the electronics are still pretty complex and i

I've been pondering the same thought recently but applied to analog cameras. Analog cameras have evolved over time, approximately according to the following: - fully mechanical - mechanical shutter with light meter - electronic control

One of the nicest data through sound implementations I came across was in a kid's toy (often the best source of innovation) It was a "Bob the Builder" play set and when you wheeled around a digger, etc the main base would pla

Not cheap, but you can get a Leica that doesn't even have a screen, it's all manual and just treats the sensor as though it were film stock. One of the things I like about the Leica digitals is that they are still rangefinder came

This is one of my favourite distractions when watching Sci-Fi films set in the future - spotting objects from now. For example: - In Luke's home in Star Wars IV there's a lot of Tupperware - https://projectswordtoys.blo

I like the principle of this and have kind of done it myself previously, however I'm currently finding it's a _lot_ harder to consider blowing up your life when you have kids that are old enough to care. I think the resentment hav

For those who favour Docker - you can do this: docker run --name archiveteam --label=com.centurylinklabs.watchtower.enable=true --restart=unless-stopped atdr.meo.ws/archiveteam/reddit-grab --concurrent 1 [username]

I've had the displeasure of re-implementing some awful systems written in a no-code platform. If you're using low-code, you're still writing software, and good software is more than a bunch of if statements and function calls

We've been using trivy [1] to audit the container builds we've been producing for a relatively security focussed project. As well as scanning for OS package level vulnerabilities it also scans for reported vulnerabilities in NPM p

Having big flashbacks to the switch from PPC to x86 here. Rosetta worked relatively smoothly during that transition so fingers crossed it will be ok here too. Though with Docker support on the mac already being a second class citizen to run

I'm a happy Postgres user and recently did some work with a government agency using Oracle - the thing that shocked me most about Oracle was the lack of transactional DDL operations which was something I'd just taken for granted i

Wow, that's a particularly nasty clickbaity headline. He only dropped out because of the disease that caused him to be bedridden for those 11 years. Maybe "Student was bedridden for 11 years..." would be more accurate.

From personal experience: using WebSockets for realtime communication with a microcontroller works really well. I've put together a number of products using ESP8266 to do this and serving out the HTML/JS from an embedded web serve

I love threads like this as I always end up discovering a new gem. I'm just going to post some of the things I've read recently in case you haven't - it doesn't really matter if a book is recent if you haven't read

I was pleasantly surprised to see this too - I bought a charge controller directly from Hugh to load control an immersion element direct from DC solar and he was extremely knowledgeable and helpful.

Personal WASM anecdote: I just implemented a WASM based 3d model boolean operation for three.js where I can intersect two models together. The pure js version ran in around 10s on a relatively simple model whereas the WASM version did the s

Not sure why this comment is being downvoted - seems like a perfectly valid concern, particularly if you've read Rainbows End by Verner Vinge

Good work, however a little feedback... This works fine at lower rates but once you hit anything greater than 120 or so there's a noticeable lag between hitting the key to rotate and the shape actually rotating - enough that the shape

The timescales involved in the manufacture of this mirror are amazing. I love the way this guy just casually states things like: "we then cool the glass ... for a few months" "the mirror will sit for the next year while we ma

It's a nice idea and really well executed but the second test just demonstrates to me how JS is not an ideal language for a beginner to learn as you're thrown straight into async execution and having to work around the fact that f

I recently did the same thing and have packaged it all up as an Ansible setup script [1]. We're using it for a Pi based robot arm [2], so having a built-in access point and a web interface to use for configuring the WiFi means you don&

Or even simpler you can use S3 redirects to send all of your old URLs to their new location on the same host. I'm currently doing this from both an old domain to a new domain and within the same domain and "It Just Works" (tm

Definitely worth a look. One of the guys behind this is pfalcon who maintains the best open development environment for programming the ESP8266 directly[1]. I love the ESP as a platform. It's low cost but still pretty impressive. Havin
