jpegoptim v1.4.4 Copyright (c) 1996-2016, Timo Kokkonen
Usage: jpegoptim [options]
-d, --dest= specify alternative destination directory for
optimized files (default is to overwrite originals)
-f, --force force optimization
-h, --help display this help and exit
set maximum image quality factor (disables lossless
optimization mode, which is by default on)
Valid quality values: 0 - 100
-n, --noaction don't really optimize files, just print results
Try to optimize file to given size (disables lossless
optimization mode). Target size is specified either in
kilo bytes (1 - n) or as percentage (1% - 99%)
-T, --threshold= keep old file if the gain is below a threshold (%)
-b, --csv print progress info in CSV format
-o, --overwrite overwrite target file even if it exists (meaningful
only when used with -d, --dest option)
-p, --preserve preserve file timestamps
preserve original file permissions by overwriting it
-q, --quiet quiet mode
-t, --totals print totals after processing all files
-v, --verbose enable verbose mode (positively chatty)
-V, --version print program version
-s, --strip-all strip all markers from output file
--strip-none do not strip any markers
--strip-com strip Comment markers from output file
--strip-exif strip Exif markers from output file
--strip-iptc strip IPTC/Photoshop (APP13) markers from output file
--strip-icc strip ICC profile markers from output file
--strip-xmp strip XMP markers markers from output file
--all-normal force all output files to be non-progressive
--all-progressive force all output files to be progressive
--stdout send output to standard output (instead of a file)
--stdin read input from standard input (instead of a file)
documentation.help is a documentation hosting platform specializing in windows documentation files. By converting “.chm” windows help files into html format, they become viewable and searchable on the web so programming questions can be answered more easily. Documentation.help contains a wide variety of help documentation from late 90s help files from pre-Windows XP computers to the latest Python documentation.
ulimit: ulimit [-SHacdefilmnpqrstuvx] [limit]
Modify shell resource limits.
Provides control over the resources available to the shell and processes
it creates, on systems that allow such control.
-S use the `soft' resource limit
-H use the `hard' resource limit
-a all current limits are reported
-b the socket buffer size
-c the maximum size of core files created
-d the maximum size of a process's data segment
-e the maximum scheduling priority (`nice')
-f the maximum size of files written by the shell and its children
-i the maximum number of pending signals
-l the maximum size a process may lock into memory
-m the maximum resident set size
-n the maximum number of open file descriptors
-p the pipe buffer size
-q the maximum number of bytes in POSIX message queues
-r the maximum real-time scheduling priority
-s the maximum stack size
-t the maximum amount of cpu time in seconds
-u the maximum number of user processes
-v the size of virtual memory
-x the maximum number of file locks
If LIMIT is given, it is the new value of the specified resource; the
special LIMIT values `soft', `hard', and `unlimited' stand for the
current soft limit, the current hard limit, and no limit, respectively.
Otherwise, the current value of the specified resource is printed. If
no option is given, then -f is assumed.
Values are in 1024-byte increments, except for -t, which is in seconds,
-p, which is in increments of 512 bytes, and -u, which is an unscaled
number of processes.
Returns success unless an invalid option is supplied or an error occurs.
I encountered this issue while trying to register a domain on Namecheap. Other domain also have issues registering this particular domain.
I suppose it could be due to the domain name being a Punycode version of ｗｈｏｉｓ (whois), which now seems to be a restricted domain keyword.
Set better keyboard repeat rates with the following commands in terminal. Before running the commands set your Key Repeat and Delay Until Repeat to the fastest options (System Preferences->Keyboard).
#disable special characters when holding keys
defaults write NSGlobalDomain ApplePressAndHoldEnabled -bool false
# normal minimum is 15 (225 ms)
defaults write -g InitialKeyRepeat -float 10.0
defaults write NSGlobalDomain InitialKeyRepeat -float 10.0
# normal minimum is 2 (30 ms)
defaults write NSGlobalDomain KeyRepeat -float 1.0
defaults write -g KeyRepeat -float 1.0
Log out and back in and your keys will be blazing fast. Don’t set them too low or you will have trouble using your keyboard to type in your password (trust me, I tried super low values and almost got locked out). If you re-open or adjust your keyboard settings from the system preferences menu, you may have to re-run these commands (so keep this post handy!)
Give yourself a fresh mac address.
- Generate a random valid MAC:
openssl rand -hex 6 | sed 's/\(..\)/\1:/g; s/.$//'
- Set it:
sudo ifconfig en0 ether 00:00:00:00:00:00
Obviously you’ll need to replace 00:00:00:00:00:00 with your generated mac address. Don’t mind the openssl error “unable to write ‘random state'”. It worked just fine.

EXIF.tools is an online file metadata viewer tool suite. This web tool is currently capable of extracting metadata from all types of files (pdf, images, videos, zip files, etc) as well as web links.
Links like: https://exif.tools/https://rehmann.co/images/logo.png make it view the http headers and exif data of an image at the same time.
Features to be built on this tool include:
- HASH Functions of Files (MD5, SHA256…)
- Location map of Image GPS data
- Prettier Interface
- Meta Data Modifier
- Meta Data Strip
