In need for quick weather forecast? Use:

curl wttr.in/<your city>

Excellent little web service based on wego and wttr.in, a web frontend for wego.

You can also use installed wego directly by obtaining  API key from here and editing ~/.wegorc like:

{ "APIKey": "", "City": "", "Numdays": 5, "Imperial": false, "Lang": "en" }

….and you get weather forecast for five days.

inxi, very versatile script to get various hardware and software data, have also interesting option -w which display local weather data: Weather: Conditions: 36 F (2 C) - Clear Time: February 4, 8:15 PM CET

…or if you use verbose variante with -x, -xx or -xxx, the output contains more data: inxi -wxxx Weather: Conditions: 36 F (2 C) - Clear Wind: From the South at 2 MPH Humidity: 87% Pressure:…

My team is currently using Gerrit for code review. Usually when a review is done, I'd need to pull down the change and edit a couple of the files in the commit based on the review that was given.

Here's my current workflow,

# download the change $ git review -d <id> # find and edit files in the last commit $ atom # commit updates # --no-edit means don't edit the commit message # though sometimes I may need to $ git commit -a --amend --no-edit # push new changes for further review $ git review -f dev

Usually it's a hassle to find all the files that may need editing from the last commit. But, I've been able to concoct a really nice solution.

According to this Stack Overflow answer, you can list all the files that were part of a given commit using

git diff-tree --no-commit-id --name-only -r <commit-hash>

And I recently learned a way to show the abbreviated commit hash of the most recent commit using

git log --pretty="%h" -n1

Combining the two I can now easily list the files that were in the last commit using

git diff-tree --no-commit-id --name-only -r `git log --pretty="%h" -n1`

Which would give the following output for example,

a.txt b.txt c.txt

The only remaining problem is how to get my editor to open up the list of files as given by the previous output. Turns out xargs is pretty neat and can handle precisely this problem (and a lot more). See here for examples of xargs in action.

Essentially, piping the output of the previous command through xargs would give

a.txt b.txt c.txt

And instructing xargs to execute the atom -n command on the input would yield the result we want.

Hence,

git diff-tree --no-commit-id --name-only -r `git log --pretty="%h" -n1` | xargs atom -n

will open all the files from the last commit in Atom.

Happy hacking!

goto – enhanced cd command

goto – enhanced ‘cd’ command replacement tool with fuzzy file finder and a directory bookmark saver, similar to autojump.

The usage is simple and effective:

goto -h, -help, h, help  # Prints the Usage

goto "location address"  # Takes you to the "location address"

goto s, -s "shortcut"  # Saves the Current Directory location as "shortcut"

goto l, -l  # Lists all the Bookmarks saved

goto d, -d…

A script to make searching for unicode chars by name a bit easier, provided you have PERL installed including CharName.pm. #!/usr/bin/env bash egrep -i "^[0-9a-f]{4,} .*$*" $(locate CharName.pm) | while read h d; do /usr/bin/printf "\U$(printf "%08x" 0x$h)\tU+%s\t%s\n" $h "$d"; done

unicode-grep name

I should see how to use the Python unicode module.
