#292I use the following tiny script to make PDFs look like they have been scanned. There are still entities that require you to physically sign a document and scan it. So far, everyone accepted PDFs like these: #!/bin/sh ROTATION=$(shuf -n 1 -e '-' '')$(shuf -n 1 -e $(seq 0.05 .5)) convert -density 150 $1 \ -linear-stretch '1.5%x2%' \ -rotate ${ROTATION} \ -attenuate '0.01' \ +noise Multiplicative \ -colorspace 'gray' $2
This is awesome!
It would be perfect if there an occasional artefact line crossing the entire page vertically could be added. You know, those lines caused by an old crusty ink jet print head. Also a visibly cast shadow by the allegedly scanned edge of the paper due to misalignment on the flat bed would add to the illusion.

#293On any system I'm working on I add a stupid simple script named `can` that moves items to the trash can. I can't say how many times it has saved my bacon avoiding accidental permanent deletions over using `rm`.
Really cool idea. For macOS, I just found out about trash https://formulae.brew.sh/formula/trash
One of the few aliases I always use is:
alias rm='trash -i'
I've also added the -i flag to the following:
alias mv='mv -i -v'
alias cp='cp -i -v'
alias ln='ln -i -v'

Sounds really cool, do you have a write-up of it anywhere?
https://blog.waleson.com/2022/03/the-worlds-first-cowboy-key... Source code here: https://github.com/jtwaleson/cowboy-bike-remote-ble I’m currently working on finalizing the PCB version, the first one had some flaws so the battery drained really quickly.
Thank you. I just recently discovered the nRF52 as a potential solution for my own BLE project. To use a keyfob as a housing is brilliant and very 'stealth'. I have no experience with the nRF52 chips, but this will be a very useful resource for me.
In your blog post you mention that "switching between 24km/h and 25km/h" is very important. May I ask why? Isn't such a speed difference almost negligible as you easily surpass it when pedalling?

#295I wrote a little script to constantly check for open appointments on ICBC (for license and motorcycle driving test slots). Has come in handy a few times already since usually everything is booked up months in advance. With this I usually find something much sooner within a few hours of running the script.

#296Easily my highest utility script so far was to get an edge while picking classes. At my university there were some classes which were very competitive and there was also system where tranches of students would get access to those classes earlier (e.g. groups of honors students -> groups of seniors -> juniors, etc). I was a lowly sophomore at the time, so I basically got what was left over. Before I could register I c…
I wrote something similar, I called it "Class Catcher" it was a VB program with the Web browser Control. I paired it with Pick-a-prof to get the best classes. I even sold a few copies via Facebook Ads.

#297Bought one of these on Swedish Craigslist: https://www.walmart.com/ip/Star-Micronics-TSP654IIU-24-GRY-S... Which was the same they used at my university in the cafeteria. Managed to plagiarise the same receipt we got when ordering food (which you needed to show the kitchen to get a plate of food) and was thus able to eat for free for the rest of my enrollment. Not even my professors could teach me to do GUIs in Java…
That's just crime... I did something similar with the QR codes in my parking garage to park for free.

#298While battling Photoshop, I ended up creating these two scripts:
Layer Labeler (sequentially labels layers with prefixes and leading 0s): https://www.middleendian.com/pslayerlabeler
Mask Placer (because Photoshop trims transparent pixels when exporting multiple layers for no fucking reason): https://www.middleendian.com/psmaskplacer

#299This is more in the "hack" category, but here is a solution for bookmarking directories[1] that I am quite fond of: mkdir ~/.marks/ export CDPATH=.:~/.marks/ function mark { ln -sr "$(pwd)" ~/.marks/"$1"; } Then: mark @name # add bookmark called @name for the current directory cd @name # jump to the bookmarked location cd @ # list all available bookmarks It can list bookmarks, auto-complete, jump to sub-directories w…

Wow. Or, is this a wind up?
Wind up?
I think it's the British slang meaning "lie to get a reaction".
This is a fascinating story. How weird to look back and see someone saying "I don't see how a lot of money could be made from this" to something that became one of the fundamental money engines of the internet.
