QUESTION
I would try to re-use some Xlisp-stat program and like to transfrom the following
...ANSWER
Answered 2022-Mar-30 at 10:32First of all, let's recall if necessary that the apostrophe '
character is a reader macro that reads the next form F
and produces a regular Lisp form (quote F)
. That's why there is a quote
symbol below.
So, in the following form:
QUESTION
I have two tables with data, let's call them table T and table B. Relevant data in T and B have a many-to-one relationship with each other, like this:
T.id B.code A 1 A 1.2 B 1.2 B 1.5 C 1 C 2 C 3 C 15 D 296etc. (This is just a rough demonstration and doesn't resemble the actual data I'm using).
I've run a count(*) query and found that the most number of times items from table T appear in table B is 8. What I want is to transpose the above table, which has thousands and thousands of entries in T and several hundred possible entries for B's corresponding value, into a 9-column table, like this:
T.id CODE 1 CODE 2 CODE 3 CODE 4 CODE 5 CODE 6 CODE 7 CODE 8 A 1 1.2 NULL NULL NULL NULL NULL NULL B 1.2 1.5 NULL NULL NULL NULL NULL NULL C 1 2 3 15 NULL NULL NULL NULL D 296 NULL NULL NULL NULL NULL NULL NULLetc.
The only search info I can find requires either manually joining B each time and excluding previous values of B.code (as I'm currently doing it), or using a PIVOT table (dynamic SQL or otherwise), which would necessarily have one column for each and every possible value of B.code (which, as mentioned, is several hundred values), neither of which are scalable options.
For reference, my code right now looks something like this:

I am trying to export an org document to html, using the program bibtex2html
, which I have installed:
ANSWER
Answered 2022-Feb-02 at 18:59I solved this problem. The error was that I was using the flatpak version of Emacs. Flatpak sandboxes applications in such a way to prevent accessing external files (in this case, bibtex2html
).
To fix, I uninstalled the flatpak version, and re-installed using https://launchpad.net/~kelleyk/+archive/ubuntu/emacs

So I eventually manage to stumble upon:

Re-using the above to do an install

QUESTION
I have two procedures, one outer procedure and one inner procedure, where I would like to understand the behaviour of the error handling. The inner procedure provokes an error and is trying to insert something in the catch block into a table. After that the error is raised, passed to the outer procedure and then should roll back the transaction.
I'm trying to understand why my code is throwing the error message:
...ANSWER
Answered 2022-Jan-05 at 17:08I would like to understand what is making this transaction a "doomed" transaction even though the XACT_ABORT is set to off.
XACT_STATE()
is -1
in the catch block so the transaction is doomed.
QUESTION
I've tried looking for answers to this, as I can't possibly be the first one to stumble across this issue, but my google-fu is failing me terribly.
Is it possible to make mypy
understand that certain functions/methods are only meant to be called from within another method?
Let's take the following code as example (E: for clarity - this is a simplified, runnable version of a real-life problem that involves a Django model instance that has an intentionally nullable field):
...ANSWER
Answered 2021-Dec-24 at 22:44You may write things such that __method_1
and __method_2
are only called from within compose_method
but, for all mypy knows, someone will import your file and calls those methods directly. Remember that Python doesn't really have a concept of private items.
What you can do is squash the error by telling mypy, in essence, "I promise that value
isn't None
here," by using typing.cast
.
QUESTION
The information I've found on cppreference is vague in this regard, so I'm asking here. Say I have two threads waiting on a condition with one having a true predicate, and the other a false one (e.g. condition.wait(lock, [=]{ return some_condition; }
). The main thread decides to randomly notify one of them with cond.notify_one()
.
Assume that the waiting thread selected is the one where the predicate is false. Is the thread going to implicitly notify the next one (if there are any left), or will it be doomed to wait until spurious wakeup?
In case only a single thread is woken up no matter whether its condition succeeds or fails, what would a good way for the first thread to try waking the next one up for a guaranteed successful notify? A naive fix:
...ANSWER
Answered 2021-Dec-22 at 01:23A notify_all() won't work, because we may accidentally end waking up multiple threads that satisfy the condition, meanwhile we only want a single one to go through at most.
That is not entirely accurate. Only one thread can lock a given mutex at a time, no matter what. If all execution threads who are waiting on the condition variable locked the same mutex (as they should) before they started to wait on the condition variable, then only one of those execution threads will successfully re-lock the mutex and "wake up", and return from wait()
. When it unlocks the mutex the next scheduled execution thread will be able to re-lock it and return from its wait()
. And so on. notify_all()
does not result in all execution threads galloping forward, full speed ahead. Effectively only one thread gets woken up, at a time, because they all must re-lock the same mutex. This single-threads them.
All execution threads get scheduled to be woken up by notify_all
, and they will all get woken up. However, effectively, only one execution thread will end up woken first, and lock the mutex. When it unlocks the mutex the next execution thread, that got scheduled to be woken up by notify_all()
, will be able to re-lock it, and so on.
Next, let's look at what wait()
with a predicate is logically equivalent to:
