PortableApps | Portable apps for the portableapps.com platform | Audio Utils library

In my work, I have got a Windows Laptop with limited access, I can't install anything because admin privilege required but lucky this website https://portableapps.com/apps have many apps that can be run without installation and admin not required even there is a portable MySQL ,Apache server etc.

Now I have got access to an old Ubuntu server without internet and no sudo privilage with the below details:-

I don't know what is the error here

I know that it is very messy but I get an exception after the client connects and send a message

The error id here

NOTE: There have been several EDITs to the question, as per comments. They are indicated below, and separated by lines. As of now, the only remaining issue seems to be that numpy cannot load, possibly (but not certainly) due to two alternative python 3.8 systems present.

I have updated my msys2 system a couple of months ago. That apparently included an update from python 3.7 to 3.8, but which left me with two broken pythons: I can start python when it is 3.7, but there are no associated packages, and I cannot start python when it is 3.8, which is the version holding packages. I do not know what went wrong with that, or what did I do wrong. I just noticed this now with the first time I mean to use python again after the upgrade.

I will describe here a sequence of steps I followed and what I found. I will post supporting code below for clarity.

1. I can start python, but pandas (e.g.) and many other packages are not found in python. Checking further, /mingw64/lib/python3.7/site-packages is essentially empty (surely emptied when upgrading to 3.8).

2. Looking for the pandas package, I found I have one version installed.

3. The pandas version is for python 3.8, surely upgraded from 3.7.

4. I redirected PYTHONPATH from 3.7 to 3.8

5. Now I cannot even start python. EDIT Now I can start python, with some misconfiguration issues (i.e., partially fixed).

Now the question is

How can I fix python3.8, which gives the error below?

ImportError: cannot import name 'open_code' from 'io' (unknown location)

How can I fix python3.8, which gives the problems below?

New problems:

5.1. I should have python pointing to 3.8, and also fix packages.

5.2. Some modules are not found, some other are.

Note: I don't know if Msys2 upgrade breaks python2-pyqt5 has anything to do with this.

1. pandas not found

I would love some help, thanks!

I am trying to use lambdas to assign functionality to window events. It already worked for assigning the "enter" button to a function.

But, for some reason, it doesn't work for the default exit button on the window. As you can see in the create_entry_window function, I used a lambda twice, and it worked only for the "Return".

The problem occurs with this line:

Since January 2020, maven has switched their repo from HTTP to HTTPS. In order my project (running with Java 5 + maven 3.1.1) to download the repos i changed in my pom.xml the repos to look to: https://repo.maven.apache.org/maven2 This worked fine and now maven tries to access the dependencies from the secure repository. Trying to build/clean my project i faced following issues:

Issue 1 Trying to mvn clean my project without any further arguments i receive following error: Could not transfer artifact org.apache.maven.plugins:maven-clean-plugin:pom:2.5 from/to central (https://repo.maven.apache.org/maven2): peer not authenticated -> [Help 1]

I tried to bypass the error by adding following arguments: mvn -Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true clean

New error: Could not transfer artifact org.apache.maven.plugins:maven-clean-plugin:pom:2.5 from/to central (https://repo.maven.apache.org/maven2): Remote host closed connection during handshake: SSL peer shut down incorrectly -> [Help 1]

Further attemp by adding alos the following argument: -Dhttps.protocols=TLSv1.2,TLSv1.1 Resolves to a new error:

Could not transfer artifact org.apache.maven.plugins:maven-clean-plugin:pom:2.5 from/to central (https://repo.maven.apache.org/maven2): TLSv1.2 -> [Help 1]

Issue 2 I tried to with a different approach by using the certificate provided from https://repo.maven.apache.org/maven2/ I import the certificate into a trust store and tried to use this with the following maven command:

mvn -Djavax.net.ssl.trustStore=C:\PortableApps\trust.jks -Djavax.net.ssl.trustStorePassword=pass -Djavax.net.ssl.keyStore=C:\PortableApps\trust.jks -Djavax.net.ssl.keyStoreType=jks -Djavax.net.ssl.keyStorePassword=pass clean

The error is the same as previous again Could not transfer artifact org.apache.maven.plugins:maven-clean-plugin:pom:2.5 from/to central (https://repo.maven.apache.org/maven2): peer not authenticated -> [Help 1]

I start to believe, that this is not goign to work with Java 5 due to the limitations of the JVM. As a last resolution, i find the usage of the insecure repo http://insecure.repo1.maven.org/maven2/ but i want to go do this as my very last option. Any further suggestions?

Note

• On another project with Java 7, i was able to resolve all the issues by using the latest maven version 3.6.3
• Since the project is compatible only with Java 5, i am limited in using maven version up to 3.1.1

My goal is to get a list of the names of all the new items that have been posted on https://www.prusaprinters.org/prints during the full 24 hours of a given day.

Through a bit of reading I've learned that I should be using Selenium because the site I'm scraping is dynamic (loads more objects as the user scrolls).

Trouble is, I can't seem to get anything but an empty list from webdriver.find_elements_by_ with any of the suffixes listed at https://selenium-python.readthedocs.io/locating-elements.html.

On the site, I see "class = name" and "class = clamp-two-lines" when I inspect the element I want to get the title of (see screenshot), but I can't seem to return a list of all the elements on the page with that name class or the clamp-two-lines class.

Here's the code I have so far (the lines commented out are failed attempts):

I installed Eclipse on my office pc, using this procedure (64 bit): https://portableapps.com/node/53284 But when i want to create a new project, it does not propose me the usual "Java project" with minimal files written. I don't have the Java Perspective so I'm trying to install the dev tools but when I want check a software site, eclipse keeps telling me it doesn't find it.

What i have done so far:

-Putted Active Provider on "Direct" in network connections

-The Eclipse Internal Web Browser works just fine (including the repositories urls and able to download files)

-I've tryed with an "/" at the end of the urls (http://download.eclipse.org/eclipse/updates/4.13/ and http://download.eclipse.org/mpc/mars/)

-I've tryed to download http://download.eclipse.org/eclipse/updates/4.13/compositeContent.jar and opened it manually. Didn't worked.

-I've added "-Djava.net.preferIPv4Stack=true" after "-vmargs" in my eclipse.ini then restarted. Same.

It keeps searching for http://download.eclipse.org/eclipse/updates/4.13/content.xml and http://download.eclipse.org/mpc/mars/content.xml which do not exist. (Unknown Host... org.eclipse.equinox.p2.core.ProvisionException)

But I don't know how to change that into compositeContent since Eclipse starts to look for compositeContent.[xml/jar]/content.xml instead.

Could you help me?

I am trying to plot a pandas Series with a line. These lines produce the output shown and a scatter plot.

I made a script that simply opens or activate specific app.
it works great but I have one issue, when the app minimized to windows tray. the Hotkey activate the Else statement part so it creates another instance of the same app.
