Orb of Osuvox vs Cataclyst – Ready Player One

What would happen of the Cataclyst had gone off inside the Orb of Osuvox? Also, what would happen if the Cataclyst were to go off on the outside perimeter of the shield created by the Orb of Osuvox? Would the barrier of the orb take the damage or would the Cataclyst prevail?


Host or domain name not found. Name service error for name=smtp.gmail.com type=AAAA: Host not found, try again

Recently, a postfix mail server running on Ubuntu gave us the following error while trying to send an email to Bob:

Jun 16 17:02:03 gateway postfix/smtp[23522]: ED3799A0D27: to=[email protected], relay=none, delay=0.02, delays=0.01/0.01/0/0, dsn=4.4.3, status=deferred (Host or domain name not found. Name service error for name=smtp.gmail.com type=AAAA: Host not found, try again)

After several attempts like changing the protocol (inet_protocols) to IPv4 (since AAAA is an IPv6 A-record) in /etc/postfix/main.cf and so on we could not get it running.. We restored the configuration file to its original and then we restarted the service:

sudo service postfix restart;

It worked!…. no idea why..


Lenovo Legion Y520 – Black Screen After RAM Upgrade to 32GB (2x16GB)

Recently, we updated the RAM modules of a Lenovo Legion Y520 from 16GB (2x8GB) to 32GB using two HyperX Impact DDR4 16GB, 2400MHz CL14 SODIMM modules.

Right after installing the new modules, after power on the laptop it would show a black screen, the fans would work at full speed but nothing else would happen. We tried placing the old RAM back inside but with no success, the same bad behavior would occur.

Since the battery of this laptop is bolted onto the chassis we thought that we might have to give it a “hard restart” or something to get it started.

Our solution

1) We powered off the laptop by long pressing the power button. 2) Then we released the button and long pressed it again until the laptop powered on and off again.
The next time we powered on the laptop it was working perfectly again!!
