Today I met with a former colleague’s son who is applying to Skype for a tester position. It turned out that he is still probably too early in his software development learning to work here but I ended up giving him some general advice hoping that it would help him focus on the right stuff when he goes off to study Computer Science at University.
Learn to use the console / terminal, bash, vim / emacs, grep etc. This is absolutley essential and the sooner you become an expert the sooner you will achieve all of your programming goals.
Install Virtualbox (https://www.virtualbox.org/) on your computer so you can use virtual machines with different OSes (e.g. Windows 7, Debian) This will allow you to test everything properly and will open up a whole world of opportunities.
(e.g. in my case I made a site that is a showcase for recordings I made when I was working as a musician / sound engineer http://xoundboy.com). Learning web technologies will ensure that you are always able to find well paid jobs
Collaborate with others on a Github community project. You can clone code from any public project and play around with it. Once you’ve improved it in some way you can ask the project owner to include your code in the project (Pull request). Through this you will meet other developers and make friends and most importantly learn how to communicate properly when creating software.
Always write automated tests for any application code you write. Learn to write unit tests first, then functional tests and then end-to-end (integration) tests. Then learn how to add these automated tests to your build script so they always run every time you hit the build button. You won’t get a decent job without knowing how to do this!
Learn almost everything here: http://stackoverflow.com – This website is pretty much the only resource you need to get online help.
If you want to work for Microsoft, learn C#.NET and WindowsAzure
Write a technology blog. Every time you solve a programming-related problem that was previously undocumented on the internet, give back to the community by writing a well thought out “How-to” and provide the documentation for others. The process of writing the blog will a) re-inforce your knowledge b) raise your online profile and c) become part of your portfolio that can be shown to potential employers in the future. (Here’s mine for an example, http://blog.xoundboy.com/ although I stopped writing regularly quite a while ago)
After a lot of farting around with different virtual network adapter types and use cases I finally settled on a networking configuration that works well for developing web apps inside a Debian Virtual Machine running inside Virtualbox on my Windows laptop.
VM needs to be accessible by the windows host even when laptop is “offline” so I can work on the plane.
When laptop is “online”, VM can also access the internet
VM should be accessed by host via a static IP address so that dev environment settings persist beyond a reboot
Two virtual network adapters in the VM’s network tab in Virtualbox:
Adapter #1: “NAT” / DHCP
Adapter #2: “Host-only” / Static IP
The NAT adapter should already be set up by default when you do a fresh install of Debian in Virtualbox. It enables the VM to access the wider internet.
Meanwhile the Host-only adapter enables the host machine to see the VM and persists even when internet connectivity drops allowing you to carry on working.
Set up the Virtualbox Host-only network.
Click File > Preferences > Network, then select “Virtualbox Host-only ethernet adapter” (or whichever host only adapter you selected in the VM’s host-only network adapter tab). Click the edit button which looks like a screwdriver. Enter an unused network in the 192.168.x.x Ip range. I’m using 213.1 because my router is on 192.168.0.1, but I could use anything in that 3rd octet except 0 I think. The netmask should be 255.255.0.0 but for some reason it still works with 255.255.255.0 – I’m still not quite sure why that is though.
Click the “DHCP server” tab and uncheck the ‘Enable Server’ checkbox – we don’t need DHCP because we’ll be using a static IP address.
Configure the networking inside the VM
Log into the VM as root and edit /etc/network/interfaces – it should look like this:
# The loopback network interface
iface lo inet loopback
You are moving a web site or folder tree from one computer to another via FTP
The source computer is Linux
You can’t use the basic FTP program because it doesn’t recurse directories
Use ncftp. Install it if necessary, cd to the root of the folder you want to put to the FTP server and then run the following command: ncftpput -u myFTPusername -p myFTPpassword -R myftp.server.com .
