You're taking your first steps into Ruby
A good introduction to programming in general. Easy on newer programmers.
I was drawn to programming, science, technology and science fiction | |
ever since I was a little kid. I can't say it's because I wanted to | |
make the world a better place. Not really. I was simply drawn to it | |
because I was drawn to it. Writing programs was fun. Figuring out how | |
nature works was fascinating. Science fiction felt like a grand | |
adventure. | |
Then I started a software company and poured every ounce of energy | |
into it. It failed. That hurt, but that part is ok. I made a lot of | |
mistakes and learned from them. This experience made me much, much |

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.
Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

Progressive apps - high-res icon, splash screen, no URL bar, etc.
