Add modules on Drupal

I have a problem concerning adding new modules on Drupal. I am using Drupal 7 and the button "Add new module" is nowhere to be found. When I try to go to "/admin/modules/install", it tells me that I don't have permission to access this page. Did someone encounter the same problem?

Auto like and auto follow on Instagram.

I was looking for a way to auto like my friends pics without engaging my mind with people's matters. In git there is many variation of auto like and auto follow Javascript code, but the problem is some does not work and the one which work you have to put some code inside it. just go to Instagram open a pic and rightclick on next pic arrow and choose the inspect now click on highlighted code, its in a format like this : class" ******* " Now you have to copy the "*******" , part and put inside your code (which you got from git).

Installing Maven

For installing Maven on mac Os or any other operating system you have to first download maven from its website then put the unzip folder in any address you want on your machine then we have to set 2 system variables for it: the first one is PATH, and the another one is HOME. Then you can check from terminal if it is installed fault free. You can check it via this command on Terminal: mvn --version the the problem reveals when you restart the Terminal! the command does not work. It is like you never had installed Maven on your machine.

Connected to the WiFi but PC won't access any page

If it didn't happen today a couple of times, maybe I would hardly come up with the third problem related to the internet, so here it is: As today everybody is at home - typical Sunday, then I counted ca. 10 devices connected to the WiFi, which I thought was the most probable source of my problem when trying to identify one. Even though I was connected to the internet the whole time, I still couldn't access websites the most of the time. Nevertheless, Skype for Business was constantly working - which made the things even more confusing.

Access Exchange Mail Server

In the course of developing an application for a client, I had to access to a Mail inbox with a software via any of the several Servers: IMAP, Exchange, POP3. After hours/days of trying, not a single server was able to access the Mail inbox- the odd was that each time I pinged the server, It was reachable, the credentials were correct and the outlook web access was also working well.

Plugging the Python script inside of Uipath (RPA Software)

Working as a developer with a brand new software for automation of business processes that relies on the logic and functions of .net, I come across many problems that are more or less solved easily and with not that much effort - especially because there is a lot of documentation available. But once I had a problem that could not be solved with the Uipath, so I had to resort to implementation with a Python code that I was going to plug into the Uipah afterwards.

Launching apps that aren't registered with Apple

Years ago as I got my first MacBook I encountered a problem of launching programs from unidentified developers on a Mac. Opening trustworthy and familiar programs from the internet was not a problem, but as soon as I wanted to try something less known or from a less known source, I got the error window saying that it is not possible to open a program from unidentified developer. Back then it wasn't so self explanatory to me how to handle this issue, nor it still is to many of my friends.

Modifying hosts.txt file

In order to be able to access via remote desktop my new client's UI2 SAP Launchpad I needed to modify my internal hosts file in order to map the right hostnames to corresponding IP addresses and therefore gain access. Being a company laptop with countless restrictions, I do not have the administrator rights over my own computer and was directed to start the incident over at IT support desk. That means at least a couple of hours of waiting for them to accept my incident and offer solution. This was not acceptable since I needed access asap.

Overleaf project share

Many university projects request LaTex as preferred or even demanded task submission format. Since ShareLaTeX didn't quite work out for many colleagues of mine, another more simple and user friendly option established and pushed through. That is Overleaf, online LaTeX text editor. Apart from the fact that two of those lately connected powers, the problem of sharing and working on the same document turned out not being a part of the free "trial" version. There are two options offered to share a document: link sharing and e-Mail invitation.

Sharing and Merging Code

During a group project at university, we needed to develop a web application. We were seven on the project and there was a lot of work to do. Thus, we decided to split the amount of work between the members. In order to share our code in the group we used a specific software called Source Tree. People were updating the general code branch when they finished their own code by adding it. But we faced a problem: the general code was never the same and errors appeared when different parts were merged.
