You can use any dictionary you want, in any language.
This command will output all single-word annotations that you have underlined in your Kindle device (provided the file) given a list of language-specific words.
If you want to learn vocabulary, this command is ideal.
XX is your device partition number like /dev/sdc1 .
to see how many inodes your partition have type:
$ df --inodes (or df -i)
Default formatting with ext4 would create small inode count for the new partition
if you need big count of inodes is the fstype news the correct one.
in debian you can see which fstype exists as template in:
$ vim /etc/mke2fs.conf
if you format default ext for a partition size with 1TB you would get 1 Million inodes (not enough for backupStorages)
but if you format with fstype news you would get hunderd of millions of inodes for the partition.
you have tune
$/etc/sysctl.conf
also with following sysconfig parameters
$ fs.file-max = XXX
$ fs.nr_open = XXX
where XXX is the count of max inodes for whole system
Used this after cloning a disk with dd to make the newly written partitions show up in /dev/
This will calculate a running standard deviation in one pass and should never have the possibility for overflow that can happen with other implementations. I suppose there is a potential for underflow in the corner case where the deltas are small or the values themselves are small.
The "-d" option for gnu's "date" command can calculate positive or negative offset from any time, including "now". You can even specify a source timezone (the output timezone can be set with the TZ environment variable). Useful! Fun! Not very well documented!
I often use it to find recently added ou removed device, or using find in /dev, or anything similar.
Just run the command, plug the device, and wait to see him and only him
-p PID and name of the program
-u on a UDP port.
-t also TCP ports
-o networking timer
-n numeric IP addresses (don't resolve them)
-a all sockets
Once you know the available frequencies for your CPU, they can be used to do things like set minimum CPU frequency for powerd so that it doesn't ramp down too slow on a server :
/etc/sysctl.conf or /boot/loader.conf:
debug.cpufreq.lowest=DESIRED FREQ HERE
or at terminal
sysctl debug.cpufreq.lowest=DESIRED FREQ HERE
Very quick way to change a word in a file. I use it all the time to change variable names in my PHP scripts (sed -i 's/$oldvar/$newvar/g' index.php)
