I attempted to build a small try-square, but my metal working skills totally suck. I tried to flatten the metal blade with a file, but I didn’t reach my own goal. It’s not perfectly straight. The square is almost 90°, it shifted a wee bit when drilling the holes for the pins. Also, the blade is 0.1mm off of being parallel. I have to try again or simply just buy one.

@prologic@twtxt.net earlier you suggested extending hashes to 11 characters, but here’s an argument that they should be even longer than that.

Imagine I found this twt one day at https://example.com/twtxt.txt :

2024-09-14T22:00Z Useful backup command: rsync -a “$HOME” /mnt/backup

Image

and I responded with “(#5dgoirqemeq) Thanks for the tip!”. Then I’ve endorsed the twt, but it could latter get changed to

2024-09-14T22:00Z Useful backup command: rm -rf /some_important_directory

Image

which also has an 11-character base32 hash of 5dgoirqemeq. (I’m using the existing hashing method with https://example.com/twtxt.txt as the feed url, but I’m taking 11 characters instead of 7 from the end of the base32 encoding.)

That’s what I meant by “spoofing” in an earlier twt.

I don’t know if preventing this sort of attack should be a goal, but if it is, the number of bits in the hash should be at least two times log2(number of attempts we want to defend against), where the “two times” is because of the birthday paradox.

Side note: current hashes always end with “a” or “q”, which is a bit wasteful. Maybe we should take the first N characters of the base32 encoding instead of the last N.

Code I used for the above example: https://fossil.falsifian.org/misc/file?name=src/twt_collision/find_collision.c
I only needed to compute 43394987 hashes to find it.

And here the Tommos camp with Mum and Dad in the trailor at Myall Lakes.
Boy I could tell you some stories here, like the time we got dozens of spiders all in the tent one night, and the time Dad yelled to Bob to get the red belly black snake that crawled over Brains sleeping bag. Up I jump grab a shovel and cut the head off. silly me !! We camped out with all our partners too.

Karen was treated like family with the 5 siblings and Mum and Dad. It was a great time. Happy camping James on your birthday!

The potato shed is fully insect proof and the tender leaves are untouched and uneaten by beetles.
Great idea, will we get potatoes and can I grow them all year round… Have to wait and see…. More larger shade houses to build to keep the beetles out.

Love the program James has given me, I just edited some 40 webpages from junk viewing to nice, in a few minutes per edit, as shown in the two programs both running in Windows Mode.

On the left is directly to the Webserver files On the right is the webpage running over the www

Really nice and easy to navigate.

OK I found this one, small enough, but where does it install to? can’t find the app, of any files of anything.
Being a total novice to Linux stuff….where is this file located and why don’t they prompt you for a folder location of the program? And why such a stupid name? Dozens to choose from and most over 300MB, not what I want - I just want Apache to run the index.html webpage or the index.php webpage. I do not need Javascript or Java programming editors….
