I once stayed late and noticed a cleaner was wearing a polo from the company I used to work for. I asked him about it and it turned out he was an engineer and was filling in for his girlfriend who owned the cleaning business. Holy red flag! I made some noise and that cleaning company was let go.

It would really help if professors would give you a taste of something applicable before diving deep into the math itself. I suffered through most of differential equations and calculus, but I happened to take a computer graphics course before linear algebra. We learned just enough math to make things work but linear algebra really took a deep dive that I was able to appreciate having had the basics around affine transformations explained in a very visual and intriguing manner.

The word fork has been used for various things in computing long before Github was around. I agree it's a bit overused in this article, but you have the Unix fork command, which creates a copy of the current process and effectively forks the execution. Older Macs of the 80's and 90's used a filesystem that allowed files to have both a data fork and a resource fork; they worked like independent streams to separate program data and embedded resources like images, sounds, etc.

I was in a pretty competitive high school marching band. We had two parallel lines moving in opposite directions, and I watched the slide of a trombone get its spit valve caught on someones shoulder strap and pulled off. The trombone player kept on making the motions as if the slide was still there, and the other marcher-with-trombone-slide-still-attached continued on until the end of the show. Fortunately we were in the last movement, but the point is that the show must go on.

It's not buying a cup of coffee that's the issue. The issue is in converting between currencies, which is no different than investing in foreign currencies. If you exchange USD for EUR, wait a while, then exchange back to USD and you've made a profit, it's taxable.

Intent or playing dumb maybe only matters as a defense against tax evasion charges, but everyone is liable to pay taxes and associated penalties for late/non-payment, even on an under the table side gig.

Well, you're literally writing step-by-step instructions that a computer will faithfully perform without deviation. Once you understand how a computer works and how to talk to it, it should be as easy as having a conversation.

I don't think this is easy, but when you've been doing it for years and years, it feels that way.

The original article was written in Russian, so I'm assuming this is an automatic translation.

Are you certain that IT can't read deleted emails? I would think there would be backups and logs in the email server.

Sure, something might fly under the radar for a while, but once there's an accusation of impropriety or a security hole discovered, anyone can look into it.

zcrackerz | 8 years ago | on: Ask HN: What is stopping you from becoming a freelancer?

It seems difficult to get into unless you know the right people. All of the freelancing sites are filled with listings looking for very specific technologies. Many have ridiculously small budgets or tons of bids that are impossible to compete with.
