#Nasa picture of the day screensaver update#

I will update this article if it gets posted to any official sources! Overall this was a nice little dabble into Bash scripting and understanding the nuances of Linux. That also means I need to work on solid error messaging and ensuring stability via some unit tests. Plans for the future include trying to get this mainlined since that seems like it would be a fun process to experience. The only issue I was tripped up on was the architecture, since it is required for the CONTROL file it made me a little unsure of if I needed one for each architecture, which I think one works since it is a very high-level script. The dpkg’ing process was very straightforward. Basically it needs to be gated via peer review, which since it is all ran by volunteers can take some time. I do not care about those sorts of things, but it is a nice thought for the future.

The script is much more succulent now, adding to configurations automatically that are persistent rather than a fragile manual setup.īefore doing the dpkg magic I decided to read up on the process and what it takes to get an application listed on the Debian/Ubuntu store. putting the background image with other background images). With those requirements in mind I decide to rewrite the script to ensure I am adhering to any standards that seem relevant (i.e. Message user to set background image via default manager if errorĪdd to XML settings to allow for resetting to APOD if background does change Run Once to create background.jpg file in /usr/backgrounds/

Install Script or symlink to /etc/network/if-up.d via dpkg Since I want to make this a package I am listing out the requirements. sh extension and mark the file as executable, now everytime the network connects to a wifi connection the script will be run. To accomplish this you add the script to /etc/network/if-up.d WITHOUT a. Finally I decided that whenever the network connects is the best time to update the background makes the most sense. Next I tried using crontab to set up a job, but that was inconsistent as the times that the computer was on varied in day to day use. With no internet the script would error out in 15 seconds, which makes for a really long login. Initially I figured that on login or anytime the password is entered would be a good idea, but the synchronous nature of the scripts running in /etc/profile any changes here introduce a delay that was substantially noticeable. Getting the script to run consistently without affecting performance was a challenge. Initially, the sure way I found to get the background image and lock screen image to be in sync is to select them via the built-in gnome-control-center settings tool. There were different commands and different settings that all changed things in marginally different ways as I explored them all. Where there are stylesheets to update such things, it really depends on the version and or theme. Setting the background became a struggle as the standard way and the way to override in random places are both highly rated Stack Exchange answers. The requirement of an API key sucks if I am trying to make the script/package more usable by anyone, which we will go into later. With the JSON payload I use a regex and grep to capture the high resolution image, and then use wget to download the image and save it as the same name every time. Requesting an API key is as simple as verifying your email address. It also checks for new images even when it's not running and shows them on the Lock Screen, Start Screen wallpaper and Live Tile, so you never miss any. Turns out that NASA has publicly available APIs that includes the APOD. 'Astronomy Picture of the Day' allows simple browsing through current and older astronomy pictures from NASA website. Getting the source data was easier than I expected. To enhance my computing experience I decided to write a script that updates my background image with the latest APOD. The default screensaver that comes with Linux is limited in the sense that it only shows a set of predetermined images. Nt This gallery was originally published in October 2010.The NASA APOD (Astronomy Photo of the Day) is one of the most profound sources for images related to astronomy. Very soon we will have a new modern gallery viewer that will make this a more pleasant experience, but until then you will have to exercise a bit of patience.
