QUESTION
I am making a simulation with C (for perfomance) that (currently) uses recursion and mallocs (generated in every step of the recursion). The problem is that I am not being able to free the mallocs anywhere in the code, without having the wrong final output. The code consist of two functions and the main function:
evolution(double initial_energy)
ANSWER
Answered 2021-Jun-13 at 04:47You're supposed to free memory right after the last time it will be used. In your program, after the while loop in recursion, Energy isn't used again, so you should free it right after that (i.e., right before return event_counter;).

I'm struggling to write a query that gets value from json column with some specific conditions. I have a table named Table1 with a column of type nvarchar(max) named Data that contains some json values. The json itself looks like this:

Answered 2021-Jun-15 at 10:38From SQL Server 2016, you can query on JSON column. See the documentation : Work with JSON data
The interesting part for you it's Analyze JSON data with SQL queries.

QUESTION
I have a situation with a Java Socket Input reader. I am trying to develop an URCAP for Universal Robots and for this I need to use JAVA.
The situation is as follow: I connect to the Dashboard server through a socket on IP 127.0.0.1, and port 29999. After that the server send me a message "Connected: Universal Robots Dashboard Server". The next step I send the command "play". Here starts the problem. If I leave it like this everything works. If I want to read the reply from the server which is "Starting program" then everything is blocked.
I have tried the following:
-read straight from the input stream-no solution
-read from an buffered reader- no solution
-read into an byte array with an while loop-no solution
I have tried all of the solution presented here and again no solution for my case. I have tried even copying some code from the Socket Test application and again no solution. This is strange because as mentioned the Socket Test app is working with no issues.
Below is the link from the URCAP documentation:
https://www.universal-robots.com/articles/ur/dashboard-server-cb-series-port-29999/
I do not see any reason to post all the trials code because I have tried everything. Below is the last variant of code maybe someone has an idea where I try to read from 2 different buffered readers. The numbers 1,2,3 are there just so I can see in the terminal where the code blocks.
In conclusion the question is: How I can read from a JAVA socket 2 times? Thank you in advance!
...ANSWER
Answered 2021-Jun-11 at 12:14The problem seems to be that you are opening several input streams to the same socket for reading commands.
You should open one InputStream for reading, one OutputStream for writing, and keep them both open till the end of the connection to your robot.
Then you can wrap those streams into helper classes for your text-line based protocol like Scanner and PrintWriter.
Sample program to put you on track (can't test with your hardware so it might need little tweaks to work):
QUESTION
I am trying to understand the following code I found online and am having trouble with the first line:
...ANSWER
Answered 2021-Jun-14 at 11:53Yes. The colon operator is a "select all, from this index" operator. Note that in the first line, its unnecesary as long as errors was already 2D, as "select the entire variable" is not something you need to specify, its by default. So it could have been
errors = (errors*trials + 0.5)./(trials + 1);.
If errors had more dimensions than 2, then the colon operator in the right hand side of the equal sign is doing something, in particular "A(:,:) reshapes all elements of A into a two-dimensional matrix. This has no effect if A is already a matrix or vector.". The one in the left hand side is useless anyway, as that line overwrites the variable.
The use of the colon operator in the second line however is well justified.
There are few other things that the colon operator means in MATLAB, read them all here: https://uk.mathworks.com/help/matlab/ref/colon.html
QUESTION
Apologies if this has been asked elsewhere / if I am using the wrong terms, I have been trying to search for the correct way to do this but with no success so far.
I have an experimental design with 3 experimental conditions using repeated measures outcomes (each participant completes 4 trials). The data I have currently is in long format (each participant ID is repeated 4 times). I am trying to calculate summary statistics for the demographic variables (age, gender, condition etc.) but I cannot figure out how to, for lack of a better word, collapse/merge the rows for each participant together to get the frequency data and/or summary stats.
Below I have a simulated dataset
...ANSWER
Answered 2021-Jun-10 at 20:44If your demographic data don't vary across treatment rounds, you can just run distinct() or unique() by id, similar to what Jon Spring suggested, like this:
QUESTION
I have documentation that requires updating in XXX project and, when cloned, I need to also clone the wiki so the documentation can be updated.
So I'm trying to add a clone alias to clone both the XXX and XXX.wiki projects, but that hasn't yielded positive results. Does anyone have a suggestion that might better solve my problem?
I've included this to show one of my many trials, but it in no way reflects the breadth of my attempts.
...ANSWER
Answered 2021-Jun-10 at 13:40This is quite difficult to do with an alias, because Git does strange things with parameters your provide to an alias, which I could not figure out.
However, you can also define a command by creating a script with the right name. git cl will invoke git-cl if it finds it on your path, and it's a lots easier to solve your problem in a bash script.
So, add a file called git-cl to your path, say, in ~/bin:

...ANSWER
Answered 2021-Jun-09 at 09:46The issue is that merge_probe_trial_dicts mutates the original list that is in df4 instead of creating a new one.
Just add .copy() as below and you should be good.
QUESTION
Today the following error appeared in my study when I try to optimize it after loading on Colab on Optuna 2.8.0. I save a study with joblib each time a trial begins or ends in a separate file for each trial. Never have I had this problem before and not sure what actually causes it.
Colab shows the following trace:

Answered 2021-Jun-07 at 23:12Just got the answer from Optuna developers:
A (private) attribute was introduced to the TPESampler in v2.8 and if you've pickled or serialized the sampler before this introduction, you'll encounter this AttributeError when unpickling it with v2.8.
The solution to this problem is re-instantiating the sampler object and substitute it to the study.sampler:
QUESTION
I want to update a .csv file's specific column/columns from another .csv file's columns. However, when I execute the following script, after lots of trials, the output .csv file either gets its old fields removed or old fields are duplicated. I also want to not add the already added fields from the input file when the script runs again.
...ANSWER
Answered 2021-May-16 at 14:10If I'm understanding right, another way to phrase what the final thing you want is for the two files put together but duplicates removed, right? From what I'm reading, it also sounds like you don't have cases where a single field is being changed - is that right?
If that is the case, you may be better off using the pandas library to bring in both files as dataframes, and then using [append] to, well, append the two dataframes, and then [drop_duplicates].
Pandas can also read the csv files and write/append your final file.

Install trials
You can use trials like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the trials component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
