It will then prompt your for new username password at next github push or login.

How to read files from dir and generate html output

When creating videos, I take snapshots of keynote, upload to website, and then manually handcraft the html to include in the show notes. It’s slow, tedious, and not a lot of fun.

So today I created a ruby script to do this for me.

imageconverter.rb

date = ARGV[0] # 2013/06
alt = ARGV[1] # iteration mechanics
basedir = "/Users/jrasmusson/Desktop"
files = Dir.glob(basedir + "/*.png")
files.each do |k|   puts "<img src=\"http://xxx/" + date + "/" + File.basename(k) + "?w=500\" alt=\"" + alt + "\" /><hr>"
end

> ruby imageconverter.rb 2013/06 “iteration mechanics” | pbcopy

<img src="http://xxx/2013/06/im-analysis.png?w=500" alt="iteration mechanics" /><hr>
<img src="http://xxx/2013/06/im-check-the-work.png?w=500" alt="iteration mechanics" /><hr>
<img src="http://xxx/2013/06/im-do-the-work.png?w=500" alt="iteration mechanics" /><hr>
...

To see the output on screen, run without the pbcopy mac command at the end which copies to clip board.

The only thing I haven’t been able to do is make this ruby script globally available from any directory (like a bash script).

If anyone has any ideas on how to do that I would be very grateful.

.bash_profile and handy scripts

Just a copy of my .bash_profile in case I ever forget it.

My scripts directory:

then
 git commit -a -m "cleanup"

 git commit -a -m "$1"

reset.sh resets my git repository

git reset --hard HEAD^
git clean -f
git merge origin/master

chmod 711 ci.sh reset.sh

Something that handles ssh

#!/bin/sh

echo "ssh mount..."
ssh -t -t root@192.168.1.107 <<EOF
mount -o remount,rw /system
exit
EOF

echo "copying..."

How to change heroku git remote

If case you ever need to map your git remote back to an existing url do this:

> git remote -v

heroku git@heroku.com:protected-reef-4420.git (fetch)
heroku git@heroku.com:protected-reef-4420.git (push)
origin git@github.com:rasmus4200/agilenutshell.git (fetch)
origin git@github.com:rasmus4200/agilenutshell.git (push)

Right now heroku is pointed at protected-reef. But I want it to point to:

hidden-ridge-8790.herokuapp.com

To do that is use this command:

> git remote add heroku git@heroku.com:hidden-ridge-8790.git

> git remote -v
heroku git@heroku.com:hidden-ridge-8790.git (fetch)
heroku git@heroku.com:hidden-ridge-8790.git (push)
origin git@github.com:rasmus4200/agilenutshell.git (fetch)
origin git@github.com:rasmus4200/agilenutshell.git (push)

Done

http://git-scm.com/book/ch2-5.html

Update: If you don’t have your heroku remote created, do this:

> heroku create
> git remote set-url heroku git@heroku.com:hidden-ridge-8790.git
