How can I easily test responsive web design?

I am currently developing a web page and want to test and debug the site for responsive web design. For example, on smaller displays, I want to display items that are usually displayed side by side on the page to instead be displayed beneath each other. Are there any other ways to achieve this other than simply resizing the browser window?

How can I easily store and share data with my family at home and beyond?

In our home, we want an easy way to share data between different PCs. Most family members have their own laptop or PC. To share data between these PCs, we have thus far used USB sticks to transfer said data. However, since new laptops from different manufacturers seem to favor different ports, it has become more and more of a hassle of the several different adapters needed. Furthermore, the data is often not really required on the PCs themselves, and so they usually end up on external drives and sticks that tend to get hidden away in drawers or lost.

How can I deal with a weak Wi-Fi signal?

We live in a 2-story flat, and the Wi-Fi signal works fine on the lower floor, where the router is located. On the second floor however, the signal seems to come in and out, even though the signal strength indicator displays around 50% signal strength. We have tried placing it in multiple locations on the lower floor but are ultimately somewhat restricted by the wall connector. Furthermore, there are no LAN connectors going to the upper floor, or anywhere else in the entire flat.

How to install Drupal 7 with Acquia Dev Desktop?

Hello, I have downloaded the latest version of Acquia Dev Desktop and am now trying to set up a Drupal 7 site using it. However, the start screen only gives me Drupal 8 and 9 as vanilla Drupal distributions and I can only get Drupal 7 if I use a modified distribution that does not fit our needs for the course. I've also tried installing older versions of Acquia, but unfortunately these fail to load the site list completely. What can I do to get a Drupal 7 site on my computer?

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.
