Cannot start Hosted Network

I have created a hosted network on my laptop in order to be able to share an internet connection between my laptop and smartphone and it worked very well. Unfortunately, sometimes I cannot start the network. I am running the command «netsh wlan start hostednetwork» but I am getting the message that the hosted network cannot be started, the group or resource is not in the correct state. But sometimes it works without problems. What could be a reason for such kind of behavior?

Share LAV Internet between laptop and smartphone

I am living in the dorm and there are no WiFi routers provided by the dorm stuff, we have only a wire access point. In order to have Internet access, you need to plug the wire into your computer or you need to buy a router by yourself. Unfortunately, at the time I don't have mobile internet (or it is not enough), but I need to connect my phone to the internet. However, I cannot/don't want to buy my own router. Is it somehow possible to share internet access between my laptop and smartphone, perhaps with a wire?

Problems with installing Bugzilla on the Windows

Bugzilla is a web-based general-purpose bug tracking system and testing tool. This program allows keeping track of outstanding problems during the development of some software products. Unfortunately, the installation process of this program is not so trivial as I would like to. The installation is command-line based and require some additional software and modules. If you want to use a Bugzilla server you need to have some compatible database management system (like MySQL, SQLite, Oracle, PostgreSQL), a suitable release of Perl 5, some special Perl modules, a compatible web server.

Postman file sending via form-data not working

I am trying to test my written node-js backend. So i try to send a file over a POST request via Postman and multipart/form-data to the backend. If i am sending the file via postman the backend the payload is undefined. But it's working if I am sending it over a classic html form. Any suggestions?

Testing Angular Components

Angular is one of the most modern frameworks for frontend development. While unit testing in backend is nothing special these days and will be practiced in nearly every project. But it's very rare to test frontend components. Which tools/frameworks would you recommend for frontend testing?

Websocket interactions in Docker

I am trying to get my Websocket server (Java) and client (JS) to interact with each other when they are both running in separate Docker containers. However, no matter what I do, I cannot get the client to even establish a connection to the server. What can be done here?

Microsoft Office 365 Abo from TU Wien

TU Wien offers software for students. One software is a Microsoft Office 365 subscription for students to a good price. For this subscription, you receive a Microsoft account to login and download the software you need. After one year this subscription expires and you have to buy a new subscription and receive a new Microsoft account login. When I bought the subscription for the second year, the account on my Windows 8 notebook was not updated to the new credentials, even after multiple successful login attempts.

Deleted .iml File in IntelliJ

Unfortunately i somehow deleted my Applications .iml file. Now my Project somehow seems broken because my modules are not displayed anymore.

Managing my ToDos

I like being organized, and I need to have a good overview of all my current todos. Sadly, I could not find any good program that would meet my expectations. What I want is a program that I can model todos out of different areas of my live with. The program should have the ability to attach text, images, checklists, and other kind of additional information to each task, create subtasks and model dependencies between tasks, i.e. task n can only be done when task n-1 is done, or as soon as task x is completed, remind me to do task x+1.
