How it works

https://docs.gitlab.com/ee/user/project/pages/

GitLab always deploys your website from a specific folder called public in your repository. To deploy your site, GitLab uses its built-in tool called GitLab CI/CD to build your site and publish it to the GitLab Pages server. The sequence of scripts that GitLab CI/CD runs to accomplish this task is created from a file named .gitlab-ci.yml, which you can create and modify. A specific job called pages in the configuration file makes GitLab aware that you're deploying a GitLab Pages website.

Overview of Steps

  • The end state has to be a directory named public that contains the site contents
  • Optionally, run a build process in a container to create the contents of the public directory
  • There has to be a pages declaration in .gitlab-ci.yml

Example 1

simple demo

  • Create the Git repo and site content
  • Go to gitlab and create new Gitlab repo
  • Clone it to your workstation
  • Add public folder with site files
  • add .gitlab-ci.yml
  • Commit and push
git clone git@gitlab.com:norrist/simple_pages_demo.git
cd simple_pages_demo/
mkdir public
echo "Hello World" > public/index.html
git add public/
vim  .gitlab-ci.yml
git add .gitlab-ci.yml
git commit -am "new page"
git push

hpr3822 :: A tale of wonder, angst and woe

Dissecting a COVID watch issued by Hong Kong Department of Health

In December of 2022, I traveled to Hong Kong, at some point en-route or in-country, I contracted covid.

Backing up a step in preparation for the trip I was required to have a negative PCR before I could board the plane from the US as well as proof of vaccination and at least one booster shot.

HKSAR Department of Health - Health Declaration Form (https://hdf.chp.gov.hk/dhehd/hdf.jsp?lang=en-us)

Upon arrival, I was required to quarantine for 3 days as well as take a home test (referred to as RAT: Rapid Antigen Test, by the locals) every day for the first 7 days

On the 2nd full day in HK, I was required to take another clinical PCR provided at a health center, free of charge.

On the third day I received my PCR and RAT tests as Covid Positive.

By law I was now required to quarantine in my hotel until I tested negative on 2 consecutive days. Since my symptoms were very mild, a sniffle and low grade temp, merely 2-3 deg above normal, I could stay in the hotel and was not required to transfer to a public health center.

I was also required to register the positive results with a government website. This registration kicked off a series of events, including a visit from a health representative. (he stood in the hall, I was not permitted to leave the room) I was Required to install an app on my phone called "Stay Home Safe'' and to wear a wristband that I presume was a GPS and possibly temp/pulse tracking device that connected to my phone by bluetooth. The agent installed the app, and synced the watch to it.

This starts out the series on Computer Strategy Games, and we begin with the game that got me hooked, the first Civilization game created by Sid Meier and published by Microprose. Though it is pretty old now, it is still fond in my heart, and in the hearts of so many other gamers. If this comes across as a love letter, so be it. We will also in this series look at where you can obtain old games, and where you can find more information about the games I cover.

hpr3819 :: Remapping Mouse Buttons with XBindKeys on Linux

I explain how I assigned different functions to the spare buttons on my trackball mice.

Remapping Mouse Buttons with XBindKeys on Linux

After a really long time of not bothering to figure out how to do this, I finally did some research and found out how to remap the extra buttons on my Kensington Expert mouse and my Logitech marble trackball mouse in a Linux environment. The tools it needed were xvkbd, xdotool, and xbindkeys. I already had the first two installed, but had never used xbindkeys before. I also used xev to identify the button numbers and key numbers.

The Kensington Expert Mouse is one that I've had for about 15 years, and it was fairly expensive when I bought it, something like $75 or $80. It has four large buttons with a large trackball in the middle and a scroll wheel going around the track ball. I bought it at a time when I was doing a lot of graphic work that required clicking and dragging and double-clicking and stuff like that. If you're using it in a Mac or Windows environment, there is a special configuration tool that you can use to set it up just how you want. I had always configured it so that the upper left and upper right buttons were used for double-clicking and click dragging. This helped reduce a lot of strain on my hands. I have never gotten this to work on Linux, though, until today.

If you want to do this yourself, the first thing to do is make sure you have these packages installed: xvkbd, xdotool, and xbindkeys.

Then create a configuration file in your home directory: 
~/.xbindkeysrc
In order to map the upper left button to "double click," and the upper right button to "click and drag," I added these lines to the configuration file: 
# Double-click assigned to button 2 (upper left)

"xdotool sleep 0.2 click 1 ; xdotool click 1"
      b:2

# Click and Drag assigned to button 8 (upper right)

"xdotool sleep 0.2 mousedown 1"
      b:8
To test the settings, simply kill the xbindkeys process and restart it by typing xbindkeys: 
user@hostname:~$ pkill -f xbindkeys
user@hostname:~$ xbindkeys

On my desktop computer I have a Logitech marble trackball mouse, and it has two small keys that are assigned to back and forward by default. This can be handy for navigating file managers and web pages, but I wanted them to be assigned to "page up" and "page down" (to make up for the lack of a scroll wheel on the mouse). Here is the configuration file for that machine:

"xvkbd  -text "\[Page_Down]""
       b:8

"xvkbd  -text "\[Page_Up]""
       b:9

I suppose I could have used xdotool for this configuration file as well, but for reasons I can't remember now, I tried xvkbd first and it worked, so I did not experiment further. I used xdotool for the Kensington because xvkbd did not have a way to perform virtual mouse clicks.

  2. solder everything together as per schematic and pictures (there is theoretically a danger in soldering cells, but I have never had a problem. Have a pair of pliers and a nearby window handy to throw them out of if anything goes wrong)

  3. wrap in cardboard and tape as per pictures

  4. add the cd/dvd drive lids(if you taped well you won't short anything and burn your house down

  5. tape dvd lids to battery

Getting into the battery for maintenance just requires a utility knife.
