This turned out a bit longer than I expected, so here's the conclusion

Echo Server/Client

Although there was a bit of ramp up time, I found this portion of the project to be a great primer on creating, connecting to and transmitting with sockets.

As far as resources go, I may very well be in the minority in that I didn't find things like Beej's Guide to Network Programming or the Linux Programming Interface to be particularly helpful as a first resource for this exercise. As thorough as they are, they were almost too indepth and I wound up inadvertently complicating things by attempting to apply the patterns in it.

The best resources for me were:

# act as a KSysGuard sensor
# provides NVIDIA GPU info via `nvidia-smi`

# Usage:
# 1. Save this script, make it executable and move it to a directory in your $PATH
# 2. Save this ksysguard sensor file for Nvidia: https://gist.github.com/Sporif/31f0d8d9efc3315752aa4031f7080d79
# 2. In KSysGuard's menu, open "File > Import Tab From File option"
# 3. Open the sensor file (nvidia.srgd)

Revert the full commit

Sometimes you may want to undo a whole commit with all changes. Instead of going through all the changes manually, you can simply tell git to revert a commit, which does not even have to be the last one. Reverting a commit means to create a new commit that undoes all changes that were made in the bad commit. Just like above, the bad commit remains there, but it no longer affects the the current master and any future commits on top of it.

git revert {commit_id}

About History Rewriting

Delete the last commit

Deleting the last commit is the easiest case. Let's say we have a remote origin with branch master that currently points to commit dd61ab32. We want to remove the top commit. Translated to git terminology, we want to force the master branch of the origin remote repository to the parent of dd61ab32:

lrascao

dash_id=xxxx
api_key=xxx
app_key=xxx

# 1. export
curl -X GET "https://app.datadoghq.com/api/v1/dash/${dash_id}?api_key=${api_key}&application_key=${app_key}" > dash.json

# 2. edit dash.json
move "graphs", "title", "description" up one level in the json hierarchy, from being beneath "dash" to being at the same level
