I am working with Linux file descriptor at the moment to communicate with an external device via serial port, and I wonder if it is possible for me to duplicate the result returned the device.
In details, I used file descriptor number 5 to read and write to the serial port /dev/ttyACM0 in a raspbian device....

ANSWERAnswered 2022-Feb-06 at 14:59
The output of
echo aa bbb ccc ddd >a.tsv is not a TSV (Tab-Separated Values) so don't name it
a.tsv as that's misleading, use
a.txt if you want it to have a suffix.
You can't easily do what you're trying to do robustly using sed since sed doesn't understand literal strings, see is-it-possible-to-escape-regex-metacharacters-reliably-with-sed. You should use a tool that does have literal string functions such as awk instead.
If I understand your code correctly it seems like this is what you're trying to do:
I was never good at maths in school and I realized that I actually need the opposite of pow(base, exponent) functions which powers some number by some factor like 2 ^ 4 = 16
Searching for answers I found that logarithm log() should be the opposite of power.
Now, I've found that to write e.g. "log 2 of 32" would in code look like
log(32) / log(2)... but how do you translate this following problem into logarithm?
I'm going to write a quick C program to print index table where all alphabetical characters are going to be printed assigned to each index starting from 0 to 26 ^ DIGITS.
Assuming DIGITS are set to 1, table will only be of size 26 (the length of alphabet from A to Z) in format index = A, index = B, ... ... index = Z. The count of DIGITS gives 26 ^ DIGITS combinations.
Now, I have this code already written:...
ANSWERAnswered 2022-Jan-25 at 19:44
You can start with
pow(ALPHABSIZE, DIGITS - 1) and use integer division to get each place value/table index. On each loop you successively reduce by a factor of
ALPHABSIZE down to 1. This lets you output left to right.
Logarithms are not necessary to compute here. To compute an integer logarithm you could nevertheless just count the number of passes through a
while/for loop in the same fashion.
I am iterating an array of structs which have a map field:...
ANSWERAnswered 2022-Jan-06 at 16:53
wrapper.Configs is a slice of structs (rather than a slice of pointers to structs),
v is a copy of the item in your slice, so updates don't change the originals.
To get this code to work, you can write:
I used to delete my branches automatically with the indication of
git fetch -p plus some git plumbing command¹, and matching for a
[gone] pattern then deleting matched branches.
Some repositories I work with enforce squashing pull requests, therefore merged commit are never made locally, and I have no way of linking content of new commits and contents of my local branches.
Some times ago I switched to
push.default current, and the feature is really better than
push.default upstream or
Since a few days, I noticed all my branches aren't deleted anymore ; and that comes from the fact when pushing, the upstream is "guessed" but never set.
If I manually set the upstream of a branch (through --set-upstream-to), then I can see my trim script working again ; but that defies the purpose of using push.default set to current....
ANSWERAnswered 2021-Dec-09 at 22:17
push.default is set to
git push -u alone (without the
... origin my-branch) will create the remote branch and set your local branch to track that remote branch.

git for-each-ref --format) will display the branch name you are used to
I am using
pytest to build a mixed Python/Rust project. During development, I frequently cycle through the commands:

You can ask Cargo to output logging information relevant to fingerprints. With Cargo 1.56.0, the appropriate environment variable is
As an example:
With pytest, I'm setting dependencies using the library
pytest-dependency. I also add markers to those tests. Here is an ECM :
ANSWERAnswered 2021-Nov-29 at 09:08
You can try this (something similar I have implemented):
Put all your test from the same category in a class, which inherits from a base class that has
test_a. Put each class in a separate file, and pass that specific file to
pytest. This way, you can get rid of markers as well.
Consider a pseudo example:
Today I updated my Android Studio to the newest stable version
(Arctic Fox 2020.3.1) and whenever I try to open xml layout, it crashes. I've tried many different things, from rebuilding to invalidating but nothing helped. After upgrade I haven't been able to uninstall Android, because uninstaller was missing (possibly due to crash). I had to restore the system to the point I had an older version. At this point I managed to reinstall Android Studio to the newest version. Even after that the program persisted to crash after trying to open xml (crashes while initializing). At this point I couldn't uninstall again, because the uninstaller is missing (I believe it's due to crash). I had to restore the system again. Any ideas what should I do or did anyone else had the same issue sometimes ago? Thank you in advance. A portion of error is listed below:

I have list v:
v <- list(c("12", "1"), c("12", "2"), c("12", "3"), c("13", "1"), c("22", "3"), c("30", "4"))
and I need to merge the lines of this list which share the same first number by joining the second numbers separated by a comma, such that the resulting list w is like this:
w <- list(c("12", "1,2,3"), c("13", "1"), c("22", "3"), c("30", "4"))
How do I go about this? Thank you in advance!

ANSWERAnswered 2021-Oct-23 at 21:25
This is a stab in the dark, as I don't understand that openssl output much, but judging by the timing and the keywords 'openssl' and 'Lets Encrypt' this has a reasonably high chance of success.
On September 30, 2021 Let's Encrypt's old Root Certificate has expired. This had a major implication that now they have started to use their own root cert which should be trusted by most devices. 'Most' part was troublesome as there are some devices alive which did not receive updates in years. So the people at Let's Encrypt found a way to still remain supported/trusted on those devices, just under one condition - its openssl version must be 1.1.0+ (which is already 4+ years old). Another important detail is that this openssl version requirement also applies to systems that would have otherwise trusted LE's new cert.
So I've seen numerous people over October scrambling to get LE issued certificates to be trusted again by their systems and the answer was always as simple as: Get your openssl / libopenssl updated to v1.1.0+
