Dear Carpentries Contribution Reviewer Team,

in order to complete my contribution step for the instructor checkout process, I proof-read lesson "Version Control with Git" and would like to suggest improvements for section "Don't Lose Your HEAD" in "Episode 5 - Exploring History".

There are basically five suggestions I have which are targeting the introduction and explanation of the state "de

This suggestion is especially with respect to Windows machines.

We recently set up the software carpentry webpage for our upcoming SWC session. I like that there were step by step instructions for the attendees on how to install Git Bash, nano and Anaconda to get ready for the workshop. There are also video tutorials which are quite helpful.

However, I notice that on the Unix Shell lesson s

I suggest either adding a short code piece to use the rename() function to change the column "genus" to "genera" (thus alerting the learners to their relationship here, while adding a new function) or changing the column name in the original dataset. Otherwise, I've found that using the correct plural for genus confuses learners who are not biologists. Although it's the R ecology lesson and one

The text uses two different articles when referring to files with the .R extension (i.e. "an .R file" and "a .R file"). This should be standardized. When referring to the file extension in speech, the ".R" is generally spoken as "dot are", so using the article "a" seems most appropriate.

The help pane could use additional calling out; the section describing mathematical functions (sin/cos/t

Admittedly, I'm not a pythonista, but I wonder whether there would be value in using bash versions of the three python scripts. For whatever reason, I'm running into problems with getting python installed correctly on my Mac. Once I got it pointed in the right direct, I ran into problems with installing numpy. It's quickly becoming a tutorial on installing python rather than make :)

Dear Community,

There is a typo in the section titled "The StringsAsFactors argument" after the second block of code that demonstrates the use of the str() function. Right after the code boxes is written "We can see that the $Color and $State columns are factors and $Speed is a numeric column", but the box shows that the $Color column is a vector of strings.

Regards,

Rodolfo

In this lesson, we learn that you can use a slice to get a substring and that "Numbers are not stored in the written representation, so they can’t be treated like strings." However, what about adding a short follow up to this part of the assignment to teach the students how to convert an integer to a string? For example, if you type in the code:

a = str(123)
print(a[1])

instead of the code

hello, in Lesson 3, item 3 you say
Modify home_scene.xml to route to the new screen components by replacing what is there with the following: function init()
? "[home_scene] init"
m.center_square = m.top.findNode("category_screen")
m.center_square.setFocus(true)
end function
However, that is what should go in the brs file. the contents of the xml file should also change

In episode _episodes_rmd/12-time-series-raster.Rmd

There is a big chunk of code that can probably be made to look nicer via dplyr:

In Instructions part 16-resources, Connecting to Nodes does not work on all clusters.

Depending on exact OS versions deployed on cluster nodes these instructions do not work.

Using ssh to connect to the cluster node on which your job runs results in
your ssh session being in a different cgroup (if cgroups are used) from your job.
Depending upon your OS, these cgroups will potentially ha
