QUESTION
I am tasked to rewrite some old software for my company and found an interesting construct inside the sources.
...ANSWER
Answered 2022-Apr-11 at 13:44Is there any reason ... why you would write a construct like that?
Only the author knows for sure (even they might not know). If there is source versioning metadata available, then associated commit message might be useful. Without more information, we can only guess what they were thinking. Some potential answers:
- The author assumed that the condition of the if-statement would have some effect, but they were wrong and the mistake wasn't tested.
- It's a vestigial result of some refactoring.
- Perhaps some code was removed that used to make the statement meaningful.
- Or perhaps it was copied from elsewhere where it did have a meaning.
- Or perhaps there used to be a series of if-statements and there was an intention to replace them with a switch, but the change was half-assed.
QUESTION
I am using a company-hosted (Bitbucket) git repository that is accessible via HTTPS. Accessing it (e.g. git fetch
) worked using macOS 11 (Big Sur), but broke after an update to macOS 12 Monterey.
*
After the update of macOS to 12 Monterey my previous git setup broke. Now I am getting the following error message:
...ANSWER
Answered 2021-Nov-02 at 07:12Unfortunately I can't provide you with a fix, but I've found a workaround for that exact same problem (company-hosted bitbucket resulting in exact same error).
I also don't know exactly why the problem occurs, but my best guess would be that the libressl library shipped with Monterey has some sort of problem with specific (?TLSv1.3) certs. This guess is because the brew-installed openssl v1.1 and v3 don't throw that error when executed with /opt/homebrew/opt/openssl/bin/openssl s_client -connect ...:443
To get around that error, I've built git from source built against different openssl and curl implementations:
- install
autoconf
,openssl
andcurl
with brew (I think you can select the openssl lib you like, i.e. v1.1 or v3, I chose v3) - clone git version you like, i.e.
git clone --branch v2.33.1 https://github.com/git/git.git
cd git
make configure
(that is why autoconf is needed)- execute
LDFLAGS="-L/opt/homebrew/opt/openssl@3/lib -L/opt/homebrew/opt/curl/lib" CPPFLAGS="-I/opt/homebrew/opt/openssl@3/include -I/opt/homebrew/opt/curl/include" ./configure --prefix=$HOME/git
(here LDFLAGS and CPPFLAGS include the libs git will be built against, the right flags are emitted by brew on install success of curl and openssl; --prefix is the install directory of git, defaults to/usr/local
but can be changed) make install
- ensure to add the install directory's subfolder
/bin
to the front of your$PATH
to "override" the default git shipped by Monterey - restart terminal
- check that
git version
shows the new version
This should help for now, but as I already said, this is only a workaround, hopefully Apple fixes their libressl fork ASAP.
QUESTION
I'm getting an error where I can't install XCode because my MacOS version is 10.15 when the requirement is version 11 or higher.
I don't want to upgrade my mac version because this is a company laptop so my other development tools might get affected.
How do I create a workaround for this?

QUESTION
ruby '2.7.3' rails (6.1.4.1)
Looks strange:
When I query some (some specific) rows in DB using activerecord and try to assign it to a variable, it raises "nil can't be coerced into Integer"
But when I don't try to assign it to a variable, it works:
...ANSWER
Answered 2022-Feb-15 at 17:50That's related to some unexpected issue related to the use of --nomultiline
or IRB.conf[:USE_MULTILINE] = false
inside .irbrc
file.
To avoid that issue, you can just skip using --nomultiline
option, when launching your rails console.
QUESTION
I am trying to do a function of decumulation with a for loop in R because the financial information provided by the company is accumulated for different concepts (this means that the info of January is only of January, the info of February is the sum of January and February, the one of March is the sum of January, February and March, etc.).
For example, let's say that I have the next dataframe:
...ANSWER
Answered 2021-Dec-29 at 18:21First note that if you apply
base function diff
to the months columns, you will get one column less but transposed.
QUESTION
Assume I have the following data frame:
...ANSWER
Answered 2021-Dec-04 at 14:32Since the years are distinct and in the desired set we only have to count how many there are for each company. (If that is not true, in general, then apply the solutions below to df2 <- unique(merge(df, data.frame(year = 2010:2012)))
in place of df. Also if we did not know the value 3 and we wanted it to equal the number of unique years in the data then we could compute it using length(unique(df$year))
.
Now, using that idea here are several alternatives. We can use table to get their frequencies and then keep those with frequency 3 or in the last case we can use dplyr's count and then filter to get those with a count of 3.

How to create a company specific parent dependency file which can be used across company specific gradle initiated projects
Sample libraries which I want to share across projects
...ANSWER
Answered 2021-Dec-21 at 16:44It depends on what is the goal of the parent POM? If it's only for the consolidation dependency versions, you can use a version catalog. A version catalog is a list of dependencies, represented as dependency coordinates, that a user can pick from when declaring dependencies in a build script.

Answered 2021-Dec-14 at 02:46Yes, we can read all the json files without partition columns. Directly use the parent folder path and it will load all partitions data into the data frame.
After reading the data frame, you can use withColumn() function to rename the date field.
Something like the following should work
QUESTION
We have a JavaFX based application which is not modularized (there are reasons, a legacy library is involved) but we build an custom runtime using jdeps
and jlink
.
We've recently rewritten the app and added a couple of new dependencies, as well as removing others. Now the script that is building the application suddenly stopped working during the jdeps
call.
Note: This is happening on Linux – I've yet to test other OS'ses, but I don't expect another result.
When the script calls
...ANSWER
Answered 2021-Dec-13 at 13:36Update: These issues have been fixed, and a patched version of jdeps
is available as part of the early access build for JDK 18 at: http://jdk.java.net/18/ (starting from build 26)
Turning my comments into an answer. There seem to be 3 bugs going on here:
- The
MultiReleaseException
seems to be becausejdeps
can not handle classes in different jars that have the same name, such asmodule-info.class
, but are stored in a differentMETA-INF/versions/xxx
directory. (JDK-8277165) - The fact that this exception is sometimes suddenly not occuring seems to be the result of a race condition in the code that checks for the above; classes of the same name having multiple versions. (JDK-8277166)
- The
MultiReleaseException
is missing it's exception message since it's thrown as part of an asynchronous task, which wraps it in anExecutionException
, which then leads tojdeps
not reporting the exception correctly. (JDK-8277123)
As for a workaround, I don't think there's a good one at this point, except maybe for editing all the jars on the class path so that they put the module-info.class
in the same META-INF/versions/xxx
directory (but, this might have other consequences as well, so you probably don't want to run with the edited jars, and only use them for jdeps
).
