Check These Out
This is regarding the command 8263 using an alias to fill in command line options for psql.
You can actually just type 'psql'. In order for that to work, you want to set environment variables PGDATABASE, PGHOST, PGUSER, and (except you're using the default) PGPORT. Also, you can add a line "host:port:dbname:user:password" (asterisk ok in some columns) to your ~/.pgpass file. Finally, if you don't like the aligned columns, you can add the line "\pset format unaligned" to your ~/.psqlrc file.
count the times a domain appears on a file which lines are URLs in the form http://domain/resource.
It finds, specifically, the connections to the HTTP and HTTPS ports as source ports. You can check for destination ports as well.
Shows all block devices in a tree with descruptions of what they are.
Lists out all classes used in all *.html files in the currect directory. usefull for checking if you have left out any style definitions, or accidentally given a different name than you intended. ( I have an ugly habit of accidentally substituting camelCase instead of using under_scores: i would name soemthing counterBox instead of counter_box)
WARNING: assumes you give classnames in between double quotes, and that you apply only one class per element.
if you haven't already done so, install lame and flac:
sudo apt-get install lame flac
To sort hidden files first, simply switch the two inner `ls` commands.
I have this aliased to `dira`
`dir` is aliased to the simpler version with no hidden files:
$ ls -l --color=always | less -R
A bitcoin "brainwallet" is a secret passphrase you carry in the "wallet" of your brain.
The Bitcoin Brainwallet Private Key Calculator calculates the standard base58 encoded bitcoin private key from your "brainwallet" passphrase.
The private key is the most important bitcoin number. All other numbers can be derived from it.
This command uses 3 other functions - all 3 are defined on my user page:
1) brainwallet_exponent() - search for Bitcoin Brainwallet Exponent Calculator
2) brainwallet_checksum() - search for Bitcoin Brainwallet Exponent Calculator
3) b58encode() - search for Bitcoin Brainwallet Base58 Encoder
Do make sure you use really strong, unpredictable passphrases (30+ characters)!
