You can find this sign on every DART station:
The sign tells us to keep behind the yellow line, that’s fine. We all know that behind is opposite to in front of, right?
Now, I would like to present you an algorithm of finding the correct side of the yellow line:
- Get in front of the line
- Cross the line to get behind it
I’ve just received a comment on WordPress with an alleged “job offer” from a charity organization. The name of the charity was “Donation Europe”.

An engineer from Google was supposed to call me on Tuesday but he didn’t. Recruitment coordinator apologized and rescheduled the call to Friday. On the scheduled time I’ve sat by the table gripping firmly my fountain pen and staring at my mobile phone’s display. The phone kept silent.

People get usually famous for the things they’ve done. Well, that’s not entirely true. They usually get famous for the things they’ve done, when they were successful. You don’t get famous for attempting and being unsuccessful, now do you?
It works the same way for the scientific publications. All scientists work hard trying various things, and when they finally succeed, they publish a paper. But what happens with all those hours spend on unsuccessful attempts? Nobody seems to be proud of blowing a whole laboratory up. Or whatever didn’t work for them. This means that other people can never learn that something was unsuccessful and they’re likely to get the same, unfeasible, idea and repeat the same research. Needless to say, unsuccessfully.
Not that I’m proud of what I’ve done here, but I will at least allow other people to find this post on Google, when searching for genetic data and relational database. I’ll describe what I did, so they at least don’t do it the way I did.
