A set of 4 graphs showing how many students in different groups got different test scores using different tools.

Students in group 1 using just AI, got an average of around 45%
Students in group 1 using just notes, got an average of around 60%, visibly higher than the AI-only group.

Students in group 2 that just used AI performed roughly the same as those in group 1.
Students in group 2 that used AI and notes did slightly better, but not as well as students that just took notes.

Even Microsoft's own paid studies show that AI harms learning.

Students that just took notes did better than those that used AI.
Students that used AI and took notes didn't do as well as those that just took notes.

The trailing space didn't make a difference for me. But yes, ss is the way to go! The equivalent command with ss is:

ss -n -t src :2049

Sweet :-)

Not as robust as it may show clients with a (randomly chosen) port of 2049 :-)

TIL that if `showmount -a` won't show the clients connected to your NFS server (with NFSv4), netstat is your friend:

netstat -anp | grep '<NFS SERVER IP>:2049' | grep ESTABLISHED

TIL that the only way to get rid of useless systemd-rc-local-generator log output is with this:

systemctl --global mask rc-local.service
echo -e '#!/bin/bash\nexit 0' > /usr/lib/systemd/system-generators/systemd-rc-local-generator

First-Of-Its-Kind Cell Transplant Brings a Cure For Diabetes Closer A patient with type 1 diabetes has begun producing his own insulin after receiving a transplant of pancreatic cells.

A patient with type 1 diabetes has begun producing his own insulin after receiving a transplant of pancreatic cells. For the first time, islet cells have been edited so they wouldn't be rejected by the patient, removing the need for immunosuppressant drugs.

Tidligere overvismand kritiserer DR-dokumentar: »Enten er det bevidst manipulation, eller også er det grov uvidenhed« Kritikken er haglet ned over Danmarks Radio efter en ny dokumentar ifølge flere sider har tegnet et billede af, at Danmark har tjent store beløb på kryolit fra Grønland. Tidligere overvismand mener, a...

Tidligere overvismand Hans Jørgen Whitta-Jacobsen mener, at det er helt legitimt at rejse spørgsmål om Danmarks kolonitid, men “hvis vi skal lave de her regnestykker, skal de laves retvisende og sandfærdigt i stedet for groft misvisende og grænsende til det manipulerende.”

I'd be happy to drop by, we also provide more in-depth workshops/tutorials. And yes, you *may* be billed by the faculty, but at very discounted prices (<50%). Let's have a chat after the Christmas break!

Nice! That sounds like a pretty ideal scenario for GenomeDK. We currently store ~20 PB data of all sorts, so your use-case is pretty normal in our world.

I assume your group is with Faculty of Health? If so, it is pretty much free, actually. The prices on the website are for "external" users, but as a HE group you're "internal" :-)

I'm at GenomeDK (genome.au.dk), but you probably already checked it out. Sounds like it would fit your use-cases quite well though (not knowing anything abut brain imaging data whatsoever).

Sounds like a sweet setup! Do multiple lab members use the R server, or is it just for you?
