Export Mercurial into Git  

Categories: Tortoise

How sad that I have to write this post... proves once more that it's all about the marketing and communication, not so much the product.

Anyway, here how you can import your hg history into git using TortoiseHg

  • TortoiseHg > Global Settings > Extensions > Enable hggit
  • create a new git repo : git init --bare .git OR  git clone --bare https://git.ken.be/my-new-repo
  • cd to your hg repository and you might create a bookmark : hg bookmarks hg
  • hg push c:/path/to/your/new/git/repo
  • cd to your git repo
  • if you used init before: git config --bool core.bare false (when you used bare command before)
  • if you used a bookmark merge hg branch into master
  • push changes to remote repository
  • delete local version and get a normal clone.

And you have a new git repo with all your hg history in it. Awesome.

Jekyll serve does not render layout 

Categories: Visual Studio

So you are using visual studio to do some jekyll github pages.

Did you save the files as UTF-8 without signature ?

  • Tools > Customize > Commands tab > Menu bar > File > Add Command... (if advanced save missing)

Add webcam stream to ipfire 

Categories: Network

Things to remember

  • Ipfire default web interface is on http port 81 or https port 444
  • Add .1 to version in /opt/pakfire/etc/pakfire.conf and do pakfire update --force so you can install addons from testing branch
  • Use pakfire to install motion
  • Motion by default streams on port 2500, but you can set this in /etc/motion.conf
  • Needed to add a video user and video group
  • The boot file /etc/init.d/motion needs some adjustments to allow starting motion at boot time
  • Set firewall rule correct to forward the port: From any to firewall red for tcp on port 2500 for webcam

Posts that helped me on the way

Adjustments to motion configuration

/etc/motion.conf

mkdir -p /var/motion/cam1
chown -R video: /var/motion/cam1
mkdir -p /var/run/motion/
chown video:video /var/run/motion/
chmod 755 /var/run/motion/
loadproc sudo -u video /usr/bin/motion

Move snapshots to dropbox

/etc/motion.conf

on_picture_save /etc/init.d/dropbox/up-snapshot.sh %f %Y%m%d %H%M%S

up-snapshot.sh

/etc/init.d/dropbox/du.sh upload $1 cam1/$2/$2-$3-snapshot.jpg && rm -f $1

Sync dropbox to main website on ipfire

sync.sh

rm -rf /srv/web/localhost/html/
/etc/init.d/dropbox/du.sh download html/ /src/web/localhost/
find /srv/web/localhost/html -type f -exec chmod 644 {} \;
find /srv/web/localhost/html -type d -exec chmod 755 {} \;

up-missing.sh

find /var/motion/cam1 -type f -exec sh -c './du.sh upload {} cam1/{}' \;
