Some student have been promoting participation in igem team. After looking at their site it seemed like some meme high school science fair stuff, but maybe I'm wrong.
Did any of you participate/encounter participants/judge such thing? Is it any good or beneficial to the cv? Or am I better just finding an internship over summer?

It depends. Not a meme though. Some key industry leaders and startup entrepreneurs have come out of iGEM. It is research leadership for babies. As in, it can be one of the few opportunities for a undergrad to lead, coordinate, and design experiments almost independently.

Since /sci/ sort of doubles as a psychology board as well, I figured I'd ask this here:

Im 24 and I forget almost everything, its been this way for most of my life. I remember elementary school well, but memory of anything after than is either nonexistant or foggy as hell. Even things as recent as 1-2 weeks ago, I have no memory of. The things I do remember have no time attached to them. Was it a month ago or half a year ago? Was it six years ago or two? A couple days or a couple weeks?

I forget almost everything about any book I read, movie I watch, game I play. I dont remember anything or anything from highschool, or from any of the jobs I've had. I can perfectly remember classmates, friends, and teachers from elementary though--I can even tell you all of their first and last names. It's like my mind is stuck as a little kid and anything after just leaks through a memory sieve.

As a kid I was molested a few times by different people. Dissociative amnesia sort of fits the bill, only its in reverse. I remember the incidents and the time period around them, but memory of everything else is what gets locked up.

the worst part is feeling so rushed. everyone's looking for a paper that will make their career. everyone's racing to be the first to publish something that sets a record, which will be supplanted in a week or two by another equally useless model. creating something that is both novel and useful is incidental and rare to the typical work that a compsci phd student performs. it's so cheap. the work feels cheap. even now, when i'm working on something that i feel is actually publishable, it feels somewhat cheap. somewhat obvious.

What's wrong with porn, fapping and perverted shit?

I'm thinking about this the whole week now and I don't know the answer.
Couldn't find any info about the right amount of sexual stuff for the average person either.

When I searched for negative effects of fapping, I only found sites that told me it's natural and healthy.
When checking reddits nofap, people mostly claim no fapping made them super human that are so much more energetic and happy than before, without any scientific proof.

My own experience?
I think I'm a little porn addicted, but I don't see that much of an issue here.
I mean I read comments of people that have 90min porn / fap session every day, while I only wank it every 2 days within 10 min.
If I wanted to avoid any sexy stuff I would need to change my whole life, stop browsing 4ch as there is sexy stuff everywhere, stop consuming any Japanese media as there is sexy stuff everywhere etc.
Not strangling the snake for 2 weeks made me realize sex is everywhere and I need blinders to avoid it.

But is it worth it?
Do I benefit from it?

>When I searched for negative effects of fapping, I only found sites that told me it's natural and healthy.
Masturbating isn't so bad, but a person here may have problems with masturbating too much, delving into degenerate porn, and perhaps having porn addiction.
>I only wank it every 2 days within 10 min
That isn't so bad, as long as it's not getting any worse.
>But is it worth it? Do I benefit from it?
Nofap/noporn is really only useful if you have a real problem (porn addiction, wasting too much time on it, shame, etc.), and it might help fix those. Nofap giving energy/life essence/whatever is mostly bullshit if you do not tire yourself out masturbating 8x per day. Any other form of self-improvement is worlds more important for general health.
