Funny timing, I've been working on essentially the same thing for Razer mice on macOS. I started this project because the basilisk v3 hyperspeed has no native mac OS support, and no documented bluetooth protocol, so I packet captured and reverse engineered it.

I'd love to hear some specific examples. Ive built several iOS apps and a whole backend (on linux) with Swift and other than lack of OSS library support for some SaaS APIs, it's been quite nice.

Sure Swift itself has some sharp edges, but not any more (or worse) than many other popular languages.

+1 to vips! It's amazingly fast and stable. I even wrote (some minimal) Swift bindings for it to be used with a Swift backend: https://github.com/gh123man/SwiftVips

I challenge myself to do it in bash one liners. I came up with a clever and shockingly simple solution to part2 using expansion and substitution.

  cat 1.txt | sed -E 's/(one)/\11\1/g; s/(two)/\12\1/g; s/(three)/\13\1/g; s/(four)/\14\1/g; s/(five)/\15\1/g; s/(six)/\16\1/g; s/(seven)/\17\1/g; s/(eight)/\18\1/g; s/(nine)/\19\1/g;' | sed -e 's/[^0-9]//g' | awk '{print substr($0,1,1) substr($0,length,1)}' | tr '\n' '+' | sed 's/\(.*\)+/\1\n/' | bc

I had a T420 in college. One day in a CS class, I bumped my (uncovered) cup of coffee and it spilled into the keyboard. I knew the laptop had ducts to drain water out, but never tested it (for obvious reasons).

I blotted up as much coffee as I could with some napkins and kept taking notes on the soaked keyboard. Worked like a charm. After drying it out, a few keys stopped working so I bought a replacement keyboard for ~$20 and swapping it out was rather fast (from memory).

I use an M1 MBP now, but I still have that thing in the basement. It still works, and I loved it. I don't miss carrying it around though (or the hilariously short battery life due to forcing discrete GPU mode so I could dock it for multiple monitors at home).

I recently replaced an old, power hungry 2U server with a laptop.

I wanted a NUC, but as it turns out a used laptop on Ebay could fetch the same specs (i7-1185G7, 16gb) for less than half the price of the equivalent NUC (without an SSD or memory).

An added bonus is you get a UPS and KVM included!

Maybe a slightly off topic question, but with the recent-ish news of Corellium winning against Apple in court to sell an iOS virtualization service. How is it that virtualizing macOS (on non-apple hardware) is still NOT ok (illegal?)?

Cloud providers are forced to host mac instances on real mac hardware for example (with a lot of strange restrictions).

Agree on all points. It's extra frustrating because GA exposes some metrics that are hard to get elsewhere like traffic sources, organic search, accurate user metrics, live geo location, etc. The only reason I keep it activated (alongside a more flexible alternative) is because it's free.

The whole UX drives me mad.

I am also frustrated with Google Analytics but one thing it does very well (that I can't seem to find elsewhere) is counting unique unregistered visitors. If I had to guess this is done with some advanced fingerprinting - but I'd be curious if anyone has found an alternative for these metrics.

It appears my Appstore agreements have fallen out of date and needed renewal. That's a somewhat embarrassing - but it should be fixed now. Gate Escape should be available in all regions, and thanks for checking it out!

Nice writeup! Building raycasting engines is fun and rewarding. You can get a lot of visual impact with very small and easy to understand code. I took a stab at it and ended up adding portals which I thought was really fun (https://github.com/gh123man/Portal-Raycaster).

I've been thinking about re-writing my raycasting engine in Rust but never really found the time - glad to see someone has done it and documented it so well!

If anyone else is interested in raycasting this page is also worth a read: https://lodev.org/cgtutor/raycasting.html

Many frameworks solve this with logger context. Add the properties you want to the logging context and all future logs in that context will have that property.

One simple example - Serilog enrichment https://github.com/serilog/serilog/wiki/Enrichment

This does however assume your entire application uses the same logger. But this is generally a requirement in services that require tracing like this.

You can go surprisingly far with a $5/mo Digital Ocean droplet and the Cloudflare free tier. Just host your website the boring way, put CF in front of it and they will cache and serve all of your static content for free.

You do have SwiftNIO (as far as making network calls) - but that leaves a lot to be desired from an out of the box usability perspective. Otherwise I totally agree, Foundation on Linux is missing some useful things.

Yes! And it's fantastic.

Last I checked golang is not packaged either and that doesn't make it any less useful on Linux.

Swift works great on Linux. You can install it manually, or use the official docker image. I prefer using docker and have had a great experience (both developing and deploying).

https://vapor.codes/ brings Swift to the server and it's quite good! Wrap that in docker and you can be running Swift anywhere pretty quickly.

You are probably pulling firebase into your preview code somewhere. You should structure your previews to depend on mock implementations of your model (or mock data). It will make the previews much faster and more reliable.

My app also uses firebase and SwiftUI with hundreds of files (views, view models, and more) with no problems.

SwiftUI has been a game changer for me as a solo dev. Sure - you have to make tradeoffs like backwards compatibility, and some strange things are missing/don't work. But - it's been a force multiplier. You can break apart complex views into components by copy/pasting its body into a new `View` struct. It's so much simpler than ripping apart a storyboard into a XIB or fighting with layout constraints. The simplicity lets you try things and fail fast without too much of an investment in design complexity.

I find that I can deliver features and iterate much faster and that makes up for the time I spend fixing edge case bugs or bridging to UIKit when I need an unsupported feature.

I keep this alias in my zshrc for exactly this purpose

  alias lzf="fzf +s --tac --bind 'enter:select-all+accept' -m"
With the added bonus that you can press return to release the filtered lines to stdout. Really useful for interactively filtering logs.
