QUESTION
I am trying to split by date and event columns. It is impossible to search for ". " some lines contain multiple sentences ending with ". " Also, some lines don't start with dates. The idea of the script was to use a regexp to find lines starting with the fragment "one or two numbers, space, letters, period, space" and then replace "point, space" with a rare character, for example, "@". If the line does not start with this fragment, then add "@" to the beginning. Then this array can be easily divided into two parts by this symbol ("@") and written to the sheet.
Unfortunately, something went wrong today. I came across the fact that match(re) is always null. I ask for help in composing the correct regular expression and solving the problem.

I think you were missing an a for the array and then a second a for the dictionary.
The following worked for me:

QUESTION
I'm following this rest json tutorial. After creating the project using maven as described in the tutorial, I start quarkus in dev mode via:
...ANSWER
Answered 2021-Mar-15 at 10:38I'll assume you use Quarkus 1.11 or higher. In 1.11 instrumentation was added as a way to not do a full restart when only body of methods changed.
Thus I could imagine that what you are seeing is that you are not actually triggering a full restart and thus your new constructor is also not called as it is reusing objects. Could that be the case ?
if yes, and you prefer to have full restart to trigger full reconstruction of your objects then you can set quarkus.dev.instrumentation=false and Quarkus will not try and optimize using instrumentation but do a full restart.
If you do believe you are creating full new objects then do please open an issue at https://github.com/quarkus/issues

I want to write a short program, which triggers the Thumbnail creation for all pictures on my network share recursively (e.g. over night) - so that when I access a folder in Thunar, the thumbs are displayed immediately.

...ANSWER
Answered 2020-Dec-04 at 10:22Hibernate has a session model when all the changes made during a session are send to the database at the end of the session. This allow some optimizations (like not sending multiple update queries in case you udpdate multiple time your entity in the same session).
To force your changes to be send to the database, you need to flush the session, you can do it via EntityManager.flush or via the persistAndFlush method.
`ConstraintViolationException should be thrown at this point.
Be careful that you will flush all the pending change of the session not the one only done by the persistAndFlush method.

QUESTION
I have installed Minio server on a Centos 7.9 and I am trying to run it as a service.
I used this guide and the minio.service file it provided to install Minio as a service: https://www.centosblog.com/install-configure-minio-object-storage-server-centos-linux/
Now when I try to enable the service I receive the following error. Could someone please kindly help?
...ANSWER
Answered 2020-Nov-18 at 09:02It turned out to be because of "Secure processes" in Centos. It supposedly hides all Linux processes not owned by the user.
I had CWP control panel so I went to "Secure processes" section of the panel and temporarily disabled it. After enabling the service you can re-enable it.
