I have two pandas DataFrames / Series containing one row each.
df1 = pd.DataFrame([1, 2, 3, 4])
df2 = pd.DataFrame(['one', 'two', 'three', 'four'])
I now want to get all possible combinations into an n*n matrix / DataFrame with values for all cross-products being the output from a custom functio...
Le $\theta$ be irrational. One can define the noncommutative torus $A_{\theta}$ as a universal algebra generated by two unitaries $u,v$ satisfying the relation $vu=e^{2 \pi i \theta} uv$. This is an abstract defnition: however one can show that this algebra is simple and can be concretely represe...
I have an existing Ubuntu 16.04 LTS install on a Dell Precision 5820 tower that has booted without issue for 2 years. After updating the BIOS via the Ubuntu Software Center (to 1.13.0), my computer will only give a black screen.
I see lots of folks discussing how BIOS updates bricked their comput...
Let $X$ be a real valued random variable. Of course, the integer part $\lfloor X \rfloor$ of $X$ is a discrete random variable taking values in $\mathbb{Z}$. We can therefore define its discrete entropy
\begin{equation}
H(\lfloor X \rfloor) = - \sum_{n\in\mathbb{Z}} \mathbb{P}( \lfloor X \rfloor ...
I have a task I found on CodeWars and I managed to solve it, however, after submitting is says:
Execution timed out: (12000 ms)
When I try to test the function is passed, but I guess it is too slow.
Before you condemn me for not finding the answer on my own. I don't really care about submitting...
I'm looking to use tools along the lines of:
grep
sed
awk
to work with docker.
listing containers:
docker container ls | awk '{print $1}'
results:
CONTAINER

How can I omit the "header"?
here's the full output for docker container ls should that prove useful:

I would like to generate sha256 hash for each log file in a folder and store that hash in a file named by the original file name suffixed with ".sha265" int he same folder.
For example, I would like to store the hash for /path/file.ext into /path/file.ext.sha256
I succeed in generating the hashes...
