GUI frustration

Posted 10-04-2021 at 01:54 PM by Skaperen

i've been "doing" computers since around 1970 and professionally since 1979, back when mainframes were my thing. i tried some smaller computers, too. most were text. i did try an Apple II and it had some graphical stuff but i mostly did things on it with text commands. through the years, the graphical user interface has improved enough that it is pretty much used by most people for most things, not counting the times people type in their text messages, email, or their LQ blog posts....

email to tech support

Posted 06-13-2021 at 05:56 PM by Skaperen

too many businesses block email to tech support even when they send responses to you by email. you know that "noreply@example.com" email address. if they have a way to manage support tickets, then they can include email responses.

Base 57

Posted 03-16-2021 at 09:49 PM by Skaperen

Base 57 is the smallest base that can represent 64 bits in just 11 characters. many programmers use higher base values to do this. that forces the use of a larger set of characters that must be used. if you choose base 62 instead of base 64 you avoid the use of special characters. so you can use just letters and number for your 11 encoded digits. with base 57 you can remove 5 characters that look similar to others. for example you might use just one character of 0, O and o instead of all 3...

new commands that create needed directories

Posted 03-16-2021 at 12:25 AM by Skaperen

i made 2 new commands (with 2 subcommands each) that i will be alpha testing. the 2 commands are named dst and par. the 2 subcommands on each are the same ... ln and mv. there is a --help option, a --version option and a --verbose option. the --help and --version options cause the command to quit after it outputs its information. the --verbose option causes status information to be output.

dst mv moves a file from one path to another, creating all the needed parent directories...
