QUESTION
I have the following exercise text:
Stack Overflow is a community where users (US), with a specific number of years of experience (Ye), can ask questions and give answers. Based on the given answers, each user earns a reputation (Re) and a badge (Ba), a sort of medal (e.g., bronze, silver and gold badge). The number of years of experience starts from the registration date (Da) on Stack Overflow. Each user can gain some money (Mo) by answering a question. Please note that the description above is not referring to the real Stack Overflow, but it’s useful to define the following exercise. The following FDs are satisfied:
- Each user has a specific number of years of experience and a specific badge
- The years of experience uniquely determine the user’s reputation and the amount of money for each answer
- For each user and for each reputation is defined a unique badge
- The registration date determines a single value of years of experience
- Each user earns a specific amount of money for each answer
The FDs I defined are the following ones:
- YeBa -> US
- Ye -> ReMo
- Ba -> USRe
- Da -> Ye
- Mo -> US
I'm not sure about the third one and the last one. For the third one I don't know if it is correct the one I wrote, or there must be two FDs (Ba -> US, Ba -> Re). For the last one I'm not sure how to represent it, because the sentence doesn't tell exactly what I wrote, and I think it is wrong because it asks me to apply the minimal cover and with these FDs it is not possible.
...ANSWER
Answered 2021-Apr-27 at 09:38A functional dependency X → Y
expresses the fact that values of the set of attributes Y
are determined in a unique way from the values of the set of attributes X
. In other words, for each combination of X
values there is a unique, specific combination of values of Y
.
Let's examine the facts described in the exercise.
- Each user has a specific number of years of experience and a specific badge
You have represented this fact with the dependency:
- Ye Ba → US
but this is exactly the opposite. With the above FD, in fact, you are saying that given a number of years of experience and a certain badge, there is only a user with such years and badge, but in the reality it is possible that different users have the same years of experience and badge. The fact specified by the sentence can instead be expressed by the FD:
QUESTION
The goal is to have a list where I upload some rows and where it automatically removes the duplicates. Still my code is not working properly. When I add new duplicates it removes them, but not the old ones. I checkd this with a simple countif. In addition the build in remoe duplicate function does not seem to work. Can anyone tell me what is the basis of this problem?
...ANSWER
Answered 2021-Feb-12 at 15:16The issue you (we) are encountering is probably due to the first column containing mixed data: numbers and strings. Manually you could do something like adding another column and using the formula
=TEXT(A1,"#")
and then copy it back and do the remove duplicates. I tried for a while to do it in VBA usingRemoveDuplicates
, but couldn't get it to work. An idea might be to write the formula to another worksheet (workbook) and then process it there and then copy it back... it all becomes rather messy.So I rather created a different solution consisting of multiple procedures that do cover some ridiculous scenarios but might come in handy in some other projects of yours.
The main procedure is
removeColumnDupes
which you call from theWorksheet Change
event code or from the two other preceding small procedures. It will call the remaining procedures when necessary. Copy all of it to the appropriate modules.In the worksheet, nothing will happen until you change a value in column
A
. If you don't want to change anything just select one of the cells and click on theFormula Bar
and press Enter. This is also considered a change. Now the duplicates have been removed and you cannot enter a duplicate in columnA
.If you don't want to use the event, you can uncomment the
Exit Sub
at the beginning of it or uncomment or delete it. Then you can useremoveColumnDupesTEST
. Note that if you haven't disabled the event solution, this will cause theremoveDupes
procedure to always run three times: once for itself (...TEST), once for writing the data, and once for clearing the contents.The
removeColumnDupesSelection
procedure may come in handy when you want to select any cell and remove the duplicates from it to the bottom-most unoccupied cell.Note when using this event, you have to be careful that it won't get retriggered again and again and 'crash'
Excel
. This is done by disabling events. See this in the event procedure.

QUESTION
I'm trying to do a migration of a 14.4k commit and 12 years old project from SVN to git.
As this is the tool that comes first when doing a basic browser research I tried to do it with git-svn
.
As it is really big I tried to do the migration from just a recent history like so :
ANSWER
Answered 2020-Dec-11 at 16:55Was I suppose to somehow resume the command that failed ?
Yes, try git svn fetch
. This will resume it, exactly.
Basically, git svn clone
= git svn init
followed by git svn fetch
. (Quite similarly to how git clone
itself is a git init
, followed by adding a remote named by default origin
, followed by git fetch
.)
In my experience with git-svn
, certain amount of fiddling around with .git/config
, and understanding the differences between refs and remotes, is often needed to get it working as you expect.
Usually, git-svn
is the remote which stands for the remote SVN server you're accessing through the git-svn
"adapter". Hypothetically, due to DVCS nature, you could have a Git repo with 3 remotes:
lab-server
cloud-archive
git-svn
(or, perhaps better renamed as e.g.svn-legacy
)
Seeing an origin
remote in your error messages tells me you probably got confused at some point, and said git clone
instead of git svn clone
. My advice would be to figure out the basics and obtain a clear mental model of what you're doing. Documentation and .git/config
may help with that.
QUESTION
NOTE - This is NOT the same as all the other questions/answers about this - Read carefully [and remember to test before you reply if you're not 100% certain it works]:-
I do NOT want to create a new reference to an object that is a copy of my original one, minus the last character, I want to actually remove the last character. See this example:-
...ANSWER
Answered 2020-Sep-27 at 03:17You can't do this. Python's str
is immutable by intent and design. There are very limited exceptions to this that constitute implementation details (In CPython, mystr += 'abc'
mutates in place if and only if the string bound to mystr
has no other references to it), but there is no means of making this work for other arbitrary mutations, nor make it work portably in all Python interpreters. If your design requires mutable str
, your design does not work in Python; the best you could do is write a str
-like class that implements your chosen behaviors, or settle for using a list
of length 1 str
s, mutating the list
as needed (and eventually ''.join
ing it back to a str
when you need a real str
).
QUESTION
Why in the following Julia code the parallel implementation runs slower than the serial?
...ANSWER
Answered 2020-Jun-20 at 00:42Your code is correct but you measure the performance incorrectly.
Note that for this use case scenario (calling external processes) you should be fine with green threads - no need to distribute the load at all!
When a Julia function is executed for the first time it is being compiled. When you execute it on several parallel process all of them need to compile the same piece of code.
On top of that the first @distribution
macro run also takes a long time to compile.
Hence before using @timed
you should call once both the fpar
and nofpar
functions.
Last but not least, there is no addprocs
in your code but I assume that you have used -p
Julia option to add the worker processes to your Julia master process. By the way you did not mention how many of the worker processes you have.
I usually test code like this:

QUESTION
I have created a .net core chat application using SignalR and I need move to next user by clicking next button. When I click the next button it will trigger the method "getRemoteClientNext" inside the Hub class
...ANSWER
Answered 2020-Apr-12 at 21:24This smells like a race condition just as SomeStudent suggested. Reading through the first couple of lines of code inside the getRemoteClient()
method, you are missing an await
.
I can't say with 100% certainty this will fix it, but I'm certain it could become a problem even if this wasn't the culprit.
