I swear, ChatGPT knows everything. Today it told me I could run the following in the developer tools console to speed up YouTube video playback beyond the “maximum” of 2x up to 3x (or more!).
document.querySelector("video").playbackRate = 3.0;

Today via r/programming: Speed matters. My favourite quote was from the end:
I like being able to make more things. I like being able to take on more ambitious projects. I like being good at what I do, and I like trying to get better.
I have a Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 06) in my new Ubuntu Trusty (14.04.1) server. As you can see here:
root@orac:/home/jj5# lspci ... 02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 06) ...
I was having a problem with the card only supporting 100baseT speeds. I downloaded and installed the Realtek driver (and rebooted):
# bunzip2 r8168-8.039.00.tar.bz2 # tar xf r8168-8.039.00.tar # cd r8168-8.039.00 # ./autorun.sh # reboot
That didn’t fix the problem.
I installed the ethtool package and ran it:
# apt-get install ethtool # ethtool p2p1 Settings for p2p1: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supported pause frame use: No Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised pause frame use: Symmetric Receive-only Advertised auto-negotiation: Yes Speed: 100Mb/s Duplex: Full Port: Twisted Pair PHYAD: 0 Transceiver: internal Auto-negotiation: on MDI-X: Unknown Supports Wake-on: pumbg Wake-on: g Current message level: 0x00000033 (51) drv probe ifdown ifup Link detected: yes
As you can see the speed is 100Mb/s, not 1000Mb/s. It says that 1000baseT full duplex is supported. I tried forcing the speed:
# ethtool -s p2p1 speed 1000 duplex full advertise 0 autoneg off
But that didn’t work. The ethtool program reported the card was still operating and 100Mb/s.
Then I tried plugging in a different cable… and that fixed the problem!
