If you can’t read the text on the default index page of your Apache HTTPD server, you can make it larger with a .htaccess file.
cat .htaccess
IndexOptions NameWidth=80If you put this in the root of the troublesome tree, it will server for that directory and all directories below it.
Not quite as succinct as I would have liked, but this does work. This is a one liner in Bash, and I had hoped to do it with a single python call once I had the repo object established. In general, diffs are not simple to do on blob objects. I had trouble using the difflib and set approaches to diffing the two files, possibly due to the fact that I was originally not decoding the streams. Thus all the splitlines work probably can be simplified.
Continue readingSoftware Development flow is an elusive beast, easily frightened away. The easiest way to lose the flow is to have a long development cycle. Building the entire Linux Kernel takes time. If you are developing a single driver that can be built as a stand alone module, you do not want to have to rebuild the entire Kernel each time you make a change to that module. If that module crashes the machine when it runs into an error, you do not want to have to wait for that machine to reboot before digging in to the debugging process.
These two guidelines lead to a pattern of building on one machine and deploying on another. Here is one way to go about this process.
With the inclusion of the Generators, the main functions seem to be in the right shape. What seems off is the naming of things. For example, we have a couple functions that take a parameter named “board” but it turns out they mean different things. The names of classes do not seem to align with what they are doing.
Lets continue with the renaming of things and see where it leads us.
But first: we can remove the exceptions to the flake8 testing, and, with the removal of some white space, we can run with all the pep8 rules intact. Now, on to renaming.
I am not going to go through each commit, but will try to provide enough context so you could follow the logic in the commits in github.
This is the last article in my Long Refactoring series. You can read the first article here.

http://adam.younglogic.com/2008/07/dependency-injection-in-c/
However, I have not been able to wrap my head around how to do that. The problem is that the DI framework, which both creates and shares the instances, will come in to conflict with the borrow checker.
While the main solving function is now cleaned up, I am not very happy with the code that checks the validation on each cell.
I am not going to go through each step here, as the pattern is well established now. Pull out of the function anything that is a distractor. Once you have the heart of the algorithm, clean it up. Then put things back together.
Continue readingI work on a system in our lab that I connect to via SSH. Fetching a file via the web and pushing it to this machine is quite slow, and I want to pull on this machine directly. The trick to make this work is to use a TOKEN from gitlab and oauth2 as the username portion of the URL. For example
curl -O https://oauth2:$CI_JOB_TOKEN@gitlab.com/api/v4/projects/$PROJECT_ID/packages/generic/$PROJECT_NAME/$PROJECT_VERSION/$FILE
The CI_JOB_TOKEN must be set to a token that has appropriate permissions on your project. Most of the values I wrote as envvars could be copy-pasted from the gitlab packages link on the web.
We regularly sync various git repos from upstream to our company speicfic Linux repository. However, sometimes when working on a development machine, I need a branch from stable that we have not synced yet. If I did a blobless clone from our repository, doing a fetch from stable is going to pull over lots of blobs that I do not need.
Instead, I want to fetch just a specific tag. I can do this by adding the tag to the fetch command, and it will pull over only those blobs
Beaker one liner using xmllint:
bkr job-results J:61 | xmllint --xpath /job/recipeSet/recipe/roles/role -
<role value="RECIPE_MEMBERS"/>
The dash at the end makes it read from stdin
Cloning the Linux Kernel repository takes time. We don’t need every commit ever for our work. But we do need multiple branches. Here are some numbers for how long it takes to do various operations.
