Physical address extension.
With 32 bits, only 4GB RAM can be addressed.
This started becoming a limitation for large servers, so Intel introduced the PAE mechanism to Pentium Pro.
To relieve the problem, Intel added 4 new address lines, so that 64GB could be addressed.
Page table structure is also altered if PAE is on. The exact way in which it is altered depends on weather PSE is on or off.
PAE is turned on and off via the
PAE
bit of cr4
.Even if the total addressable memory is 64GB, individual process are still only able to use up to 4GB. The OS can however put different processes on different 4GB chunks.
"Quantum interconnect" refers to methods for linking up smaller quantum processors into a larger system.
As of 2024, seemingly few organizations developing quantum hardware had actually integrated multiple chips in interconnects as part of their main current roadmap. But many acknowledged that this would be an essential step towards scalable compuation.
The name "quantum interconnect" is likely partly a throwback to classical computer's "chip interconnect".
Sample usages of the term:
- news.mit.edu/2023/quantum-interconnects-photon-emission-0105
Researchers have demonstrated directional photon emission, the first step toward extensible quantum interconnects

Let's try with 66. First there way too much data, 9 GB, let's cut it down:
n=66
time awk '$3~/^alive,/ { print $1 }' $n | uniq -c | sed -r 's/^ +//;s/ /,/' | tee $n-up-uniq-c
OK down to 45 MB, now we can work.
grep -e '66.45.179' -e '66.104.169' -e '66.104.173' -e '66.104.175' -e '66.175.106' '66-alive-uniq-c' | tee 66hits

Controlled quantum gates are gates that have two types of input qubits:These gates can be understood as doing a certain unitary operation only if the control qubits are enabled or disabled.
- control qubits
- operand qubits (terminology made up by Ciro Santilli just now)
The first example to look at is the CNOT gate.

Ciro Santilli learned this expression from Angry Video Game Nerd.
Poet, scientists and warriors all in one? Conquerors of the useless.
A wise teacher from University of São Paulo once told the class Ciro Santilli attended an anecdote about his life:It turned out that, about 10 years later, Ciro ended up following this advice, unwittingly.
I used to want to learn Mathematics.But it was very hard.So in the end, I became an engineer, and found an engineering solution to the problem, and married a Mathematician instead.

feedsdemexicoyelmundo.com JavaScript reverse engineering Updated 2025-01-10 +Created 1970-01-01
The JavaScript of each website appears to be quite small and similarly sized. They are all minimized, but have reordered things around a bit.
For example consider: web.archive.org/web/20110202190932/http://feedsdemexicoyelmundo.com/mundo.js
First we have to know that the Wayback Machine adds some stuff before and after the original code. The actual code there starts at:and ends in:
ap={fg:['MSXML2.XMLHTTP
ck++;};return fu;};
We can use a JavaScript beautifier such as beautifier.io/ to be abe to better read the code.
It is worth noting that there's a lot of
<script>
tags inline as well, which seem to matter.Further analysis would be needed.

Marc made $58.4m from the sale of LightLogic, an optoelectronics company he founded, to Intel in 2001:
