A simple patch for mtpfs to close a few bugs. The severity of these bugs is unknown so the priority of fixing them depends on your risk tolerance. The most certain of the bugs occurred once during an rsync and the drawback was that the user had to reboot their phone.Read more »

A certain game reminded me of a cryptography trick that I learned years ago and haven't had the opportunity to share. First, let's talk substitution ciphers. I'll give two challenges, one with spaces and one without.

The trick for the first one is to look at the list of possible two-letter words. Here is the top 101 words in order of occurrence in AI3.
There are plenty of two letter words in both challenges, so it should be fairly straightforward how to solve those. Once you've tried values for the two letter words, see what substituting the rest of the characters does to other words. You might find obvious words. If you have a dictionary on your system, you can use grep to find a word automatically. If you have the AI3 wordlist, you automatically get the results in order of likeliness which improves the search many times. It also contains words that a normal dictionary doesn't have.Read more »
