This is the beginning of my C# development series of articles. As such, i will make a classic “Hello, World” example application.

I am going to use Microsoft Visual Studio 2019 Community edition to write and compile my C# code. Right now it’s free for everyone and if you’re on Windows, i recommend downloading and installing it - it will make your life a lot easier. You can download it from here. If you are on Mac, there is a Visual Studio version for that. If you’re on Linux - you can download Visual Studio Code from the same page.

Hey everyone.
Recently i decided to get into development of native mobile apps using React Native.
React requires a Ruby gem called Cocoapods, which on it’s side requires GCC (Gnu C Compiler) to compile and install properly.
If the GCC is not configured properly, it will result in the error “configure: error: C compiler cannot create executables”.

To fix this error we will need 3 things:

• Install XCode
• Install XCode command tools
• Configure XCode to use the installed command tools correctly

You can Install XCode by downloading it from the App Store.

Installing the command tools can be done by executing the following command in the terminal

1

xcode-select --install

If you have an old version of the command line tools, you can update them with the following command:

1
2

sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install

As a last step, you have to open XCode, go to the menu “XCode->Preferences”, the “Locations” tab and choose an item from the dropdown menu near “Command Line Tools”, as shown in this image:

After that you can run “pod install” again and you’ll be greeted with a happy green “Pod installation complete!” message.

The tenth generation of iPhone - iPhone 7 and iPhone 7+ were released on 16th September 2016 and now being three years old. Succeeding the iPhone 6 and iPhone 6 Plus as flagship devices, they were a huge success. Despite being the first iPhone to remove the headphones jack, they were some of the most selling devices well into 2018. Overcoming most of the shortcomings of the previous model, the iPhone 7 and iPhone 7 Plus are incredibly well designed phones and are absolutely worth buying even in 2019 - 3 years after their initial release. Usually after such period of time, most other phones become irrelevant and outdated, which definitely is not the case here.

Some of you may have noticed, there is a fight for fame in the most used on-demand video streaming website - YouTube. The currently most subscribed celebrity - Felix Arvid Ulf Kjellberg (PewDiePie), may soon be surpassed by the Indian music record label T-Series. Pew’s fans called everyone for action, to subscribe and keep him at the top place. That’s all fine, but when do you know it has gone overboard? Three days ago, I’ve received the following spam email from one of my hosting providers…

Spam from 000webhost daughter company of Hostinger.

The latest version of the Mozilla foundation browser - Firefox Quantum 63.0, introduces an issue with some websites, where even though there is a valid security certificate, it doesn’t load the page. The below image shows a website that i usually access using Firefox. Other browsers like Edge and Chrome validate the certificate correctly and display the page.

Previously there was an option to add an exception and continue to the site anyway (which is also described on the help page), but in this situation it doesn’t exist, probably because the certificate is found as valid. While i do not know the source of this issue, the fix is very simple if you encounter it - click on the shield icon in front of the URL and “Clear Cookies and Site Data”. In the popup click OK after verifying the domain name - this will clear all temporary data in your browser for this website and open it clean, the next time you load the page.
