This ultimately determines which Java is used by a bunch of tools.
TODO is there a way to update it sanely in Ubuntu: askubuntu.com/questions/175514/how-to-set-java-home-for-java to always match the default
java executable?lspci is the name of several versions of CLI tools used in UNIX-like systems to query information about PCI devices in the system.On Ubuntu 23.10, it is provided by the pciutils package, which is so dominant that when we say "lspci" without qualitication, that's what we mean.
Good article about its history: en.bitcoin.it/wiki/BitcoinTalk
Founded by Satoshi Nakamoto, making it the earliest and one of the most important Bitcoin communities. TODO official in any way? Who founded it?
Some notable appearances:
- in 2010, it is where Laszlo's pizzas offer was announced
- it was used e.g. on the Mt. Gox investigation: youtu.be/tJ-TsrK6SuY?t=2018
- Jimmy Zhong's investigation: youtu.be/pxvd1YOMGxU?t=1004
Located in Tennessee in the East of the United States.
The precursor organization to ORNL was called Clinton Engineer Works, where groundbreaking Manhattan Project experiments and nuclear production took place during World War II
Some key experiments carried out there include:
- 1943: X-10 Graphite Reactor: prototype Plutonium breeder reactor
- isotope separation to purify Uranium-235:
Most notable example: gallium arsenide, see also: gallium arsenide vs silicon.
An important class of semiconductors, e.g. there is a dedicated III-V lab at: École Polytechnique: www.3-5lab.fr/contactus.php

One of Ciro Santilli's favorites.
Adds up chemical energy and kinetic energy.
Wikipedia mentions however that the kinetic energy is often negligible, even for gases.
The sum is of interest when thinking about reactions because chemical reactions can change the number of molecules involved, and therefore the pressure.
To predict if a reaction is spontaneous or not, negative enthalpy is not enough, we must also consider entropy via Gibbs free energy.
Within the The Holy Trinity of popular Brazilian music, Caetano has the most New Age religious feel to him. He is also perhaps the most varied of the trinity however, also covering heavier topics at times.

Basic analogue phones connected to the public exchange use two wires mainly arranged as a twisted pair to reduce noise. The voice signal is differential (the voltage in one wire equal and opposite to the other) biased above ground by 48V. Using a twisted pair reduces induced noise because the noise signal will induce an equal voltage in each wire and because the signal is transmitted as the difference the effect of the induced noise will be dramatically reduced.
