QUESTION
I'm trying to get Jena ARQ as suggested in O'Reilly SPARQL 1.1 book so I can follow along with the query examples in the book. I've downloaded apache-jena-.4.0.zip from jena.apache.org/download/index.cgi and follwed the instructions to extract and set JENA_HOME and PATH environmet variables.
When I run ARQ.bat from windows cmd terminal I get
...ANSWER
Answered 2022-Mar-19 at 18:04Class file version 55.0 is equivalent to Java 11 (can be seen for example here). However, the Java version you install from java.com is Java 8. Therefore you need to use at least Java 11, but newer versions (e.g. Java 17) might work as well.
You can obtain newer versions of the Oracle JDK here, or you can use Open JDK builds, for example from here. See for example this question for differences between the Oracle JDK and Open JDK.
QUESTION
let me know... how to setup worker for the arq job in python.
...ANSWER
Answered 2022-Mar-14 at 11:45You need a function that the worker should run. Otherwise the worker would be quite unnecessary.
For example with the function the_tasks, you add it to the functions argument of the worker:
QUESTION
Summary: I am trying to use the documentation on JavaScript SPARQL Functions to get a minimal working example of calling a custom javascript function, but it results in a scriptEngine null error.
Details: I setup a fuseki environment following the Docker instructions, so:
...ANSWER
Answered 2022-Mar-10 at 10:28In Apache Jena 3.16.0, the JS engine was Nashorn. Nashorn was deprecated in Java 11 and removed in Java17.
An earlier Java version will have Hashorn in.
Now Jena version 4.4.0 uses the javascript engine of choice which has been added to the classpath, and hence needs to be in the dockerfile. Jena testing uses GraalVM.
QUESTION
I am using SQlalchemy for the database connection to a MySQL server in my FastAPI project, which consists of the actual API and a backend worker written using arq. Both share the same codebase, models and hence also the same database code.
I'm essentially creating the database connection like this:
...ANSWER
Answered 2022-Feb-20 at 12:29In my case I forgot to close the DB connection in some instances and therefore didn't return the connection to the default pool. The logs actually told me about that. I'm not sure why that led to the BrokenPipe error above, but fixing the two affected worker methods solved the issue.
QUESTION
I'm trying to write a specific program that reads data from a file but I realized that when I read the file with fgetc, if I use fgets later, it doesn't have any output.
For example, this code:
...ANSWER
Answered 2021-Dec-07 at 18:33TLDR: rewind(arq); is what you want
When you read from a file, the internal file pointer advances as you read, so that each subsequent read will return the next data in the file. When you get to the end, all subsequent reads will return EOF as there is nothing more to read.
You can manipulate the internal file pointer with the fseek and ftell functions. fseek allows you to set the internal file pointer to any point in the file, relative to the beginning, the end, or the current position. ftell will tell you the current position. This allows you to easily remember any position in the file and go back to it later.
SYNOPSIS
QUESTION
I'd like to write a program that gets an integer in a file, sums it with a input number and replace the previous integer in the file with the result of the sum. I thought the following code would work, but there's a 0 written in the file that remains 0, no matter the integer I input. What am I doing wrong?
...ANSWER
Answered 2021-Dec-07 at 12:15You can try reading and writing the input file separately as shown below:
QUESTION
#include
#include
using namespace std;
struct review {
string text;
string date;
};
void getRegistry(int i) {
review* reg = new review;
ifstream file;
file.open("test.txt", ios::binary);
if (file) {
file.seekg(i * sizeof(review), ios::beg);
file.read(reinterpret_cast(reg), sizeof(review));
cout << reg->text;
file.close();
}
delete reg;
}
void generateBinary()
{
ofstream arq("test.txt", ios::binary);
review x;
x.text = "asdasdasd";
x.date = "qweqweqwe";
for (int i = 1; i <= 1000000; i++)
{
arq.write(reinterpret_cast(&x), sizeof(review));
}
arq.close();
}
int main() {
generateBinary();
getRegistry(2);
return 0;
}
ANSWER
Answered 2021-Nov-20 at 14:28The operator sizeof (review) does not return the length of containing strings. This is due to the fact that string class contain pointers to real strings, which are located in a separated location of the memory, allocated dynamically. You should use explicitly the length of strings, and write explicitly the strings instead of the class. Same thing with reading from file. Read strings first, then attribute to review.
QUESTION
I'm experiencing problems when I try to create a PDF from HTML using Lambda Function, I'm receiving the error below:
...ANSWER
Answered 2021-Sep-02 at 16:36I ran into this issue, too. I fixed it by downgrading html-pdf from version 3.0.1 to version 2.2.0.
The release notes for the newer version are less than inspiring: "Not sure this module is even usable without installing phantomjs manually"
Perhaps there's a way to make version 3 work with lambda. But downgrading was a quick win for me.

I am currently working with a large dataset I retrieved from the crossref API in which I retrieved information on scientific papers based on a DOI search.
Currently the large list contains of ~3500 elements. Each of these elements is a list of their own consisting of the metadata 'meta', the actual relevant data 'data' and an irrelevant list 'facets'.
This is an example of two of the lists based on two DOI's:

Answered 2021-Oct-25 at 16:55Like this? Note - it is better to include a Minimal reprex that includes a toy data set, rather than a snapshot of what you have. This way the question will likely get answers faster.

Install arq
You can use arq like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
