I made a macOS script that OCRs text on screen. It is super handy for dealing with everything from scanned documents with account numbers to web pages with text in images.

When I press F16, I get an image capture cursor, and the area selected is turned into text.

I made a crappy little web tool[1] that lets me paste a timestamp into it, and will show me that time in my current timezone by default (I think that's just hardcoded haha), or in another one that I select. I mostly use it when reasoning about logs -- for some reason my mind has never gotten used to mapping UTC time to my time. It also has a selector for the source timezone, but that doesn't work, for reasons I've fo…

Yeah, nice benefit of living in the UK is local time is at most one hour out from UTC. Downside is it's easy to code timezone bugs in winter and not notic until summer!

Earlier quoted context omitted.

Protocol complexity, number of vulnerabilities in the codebase, and for ssh there's reliability as well. (SSH tunnels multiplex connections over a single TCP connection, whereas TLS and spiped map one TCP connection to one TCP connection.)

But what's wrong with stunnel?

Protocol complexity and the number of vulnerabilities in the codebase.

This one is hardware and software.

I made webUSB postage scales and a webUSB thermal printer.

We used to use Dymo label printers etc, but macOS' printer queue would get stuffed up every 200 or so prints.

The advantage of a webUSB based solution was:

  - No OS based printer queue to get gummed up
  - Super-fast (just ZPL printer commands being sent down the wire)
  - One-click to create a postage label
  - Automatic label printing when a new order comes in (Websocket + WebUSB)
  - Live parcel weights and prices updated via Javascript
We used to create labels by copying and pasting between Shopify and Australia Post. This hardware saves us ~4min per parcel.

Edit: I'll clean the script up and make it available as a "Show HN:" soon.

You have a hit on your hands. Let me (@NetOpWibby) know if you need a website built.
