Development Tools

GitLab CE

GitLab on Ubuntu

sudo apt-get install curl openssh-server ca-certificates postfix
curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh | sudo bash
sudo apt-get install gitlab-ce
sudo gitlab-ctl reconfigure

Change external URL

Set the external_url [2] in /etc/gitlab/gitlab.rb:

external_url "https://example.com/gitlab"

Reconfigure GitLab:

sudo gitlab-ctl stop unicorn
sudo gitlab-ctl stop sidekiq
sudo gitlab-ctl reconfigure
sudo gitlab-ctl restart

On Apache configure reverse proxy:


ProxyPass /git/ https://192.168.x.xx/git/
ProxyPassReverse /git/ https://192.168.x.xx/git/
SSLProxyEngine On
SSLProxyVerify none 
SSLProxyCheckPeerCN off
<Location /git>
  RewriteCond     %{HTTPS}   Off
  RewriteRule     .*         https://%{HTTP_HOST}%{REQUEST_URI} [R,L]

... and generate (or copy+rename pem) cert and key to

cd /etc/letsencrypt/live/mh.dyndns.me/
cp privkey.pem ~/mh.dyndns.me.key 
cp cert.pem ~/mh.dyndns.me.crt
scp mh.dyndns.me.crt mh@
scp mh.dyndns.me.key mh@

on copy to

  • /etc/gitlab/ssl/mh.dyndns.me.key
  • /etc/gitlab/ssl/mh.dyndns.me.crt

Set logging of IPs via proxy [3]:

# Each address is added to the the NGINX config as 'set_real_ip_from <address>;'
nginx['real_ip_trusted_addresses'] = [ '', '', '2001:0db8::/32' ]
# other real_ip config options
nginx['real_ip_header'] = 'X-Real-IP'
nginx['real_ip_recursive'] = 'on'

CI-CD Pipelines

add local host to /etchosts and use certs

cp /etc/gitlab/ssl/mh.dyndns.me.* /etc/gitlab-runner/certs/

  4. Expand the General Purpose Tools group, and tick Marketplace Client.
  5. Click Next, and again, accept the terms and conditions and click Finish.

This will install the marketplace. You will need to restart Eclipse for the change to take effect. Install m2e

  1. Open Eclipse, go to Help -> Eclipse Marketplace...
  2. Wait for it to finish loading.
  3. Enter "maven" in the search box and press return.
  4. Click the Install button next to Maven Integration for Eclipse by Eclipse.org (NB: there is a similar item above called "Maven Integration for Eclipse WTP" by Red Hat, Inc; this is not the correct one).

VisualStudio Code

Download and install.


curl -sL https://deb.nodesource.com/setup_7.x | sudo -E bash -
sudo apt-get install -y nodejs

sudo npm cache clean -f
sudo npm install -g n
sudo n stable
sudo n 6.9.4
sudo n 4.7.2
sudo ln -sf /usr/local/n/versions/node/<VERSION>/bin/node /usr/bin/node

To upgrade to latest version (and not current stable) version, you can use

sudo n latest

To undo:

sudo apt-get install --reinstall nodejs-legacy     # fix /usr/bin/node
sudo n rm 6.0.0     # replace number with version of Node that was installed
sudo npm uninstall -g n

AVR ISP mk2: Programmer Trick

I got my nice Atmel in-system-programmer, but unfortunately, the IDE on Linux couldn’t use it to burn code onto the MCU.

First install the uisp package:

sudo apt-get install uisp

The fix for this was to create a new file /etc/udev/rules.d/99-avrispmkii.rules with the following line:

BUS=="usb", ACTION=="add", SYSFS{product}=="AVRISP mkII", MODE="0666", SYMLINK+="avrdev"

Restart udev

sudo service udev restart

Re-plugging the ISP, the device node was world writable and the IDE could do its magic.

avrdude should work now:

avrdude -c avrisp2 -P usb -p m8 -U flash:w:avr-tst.hex
