Das EasyGate1541 jetzt auch für die 1541-II
Das EasyGate1541 war bisher nur für die “alte” 1541 erhältlich. Die spätere 1541-II bekam von Commodore ein anderes Gate-Array, das noch mehr Funktionalitäten integriert hat. Es war an der Zeit, dass eine Alternative geschaffen wurde.

Day 32/100: #Leetcode daily question
Question: 1671. Minimum Number of Removals to Make Mountain Array
This is a very good difficult question, and I obviously need to look a solution. This was solved using the lowest increasing decreasing subarray method.

I'm obsessed. 50% memory savings with PHP arrays have driven me crazy 
For the past few weeks, my after-work research on PHP arrays has dominated my free time. The 'Never* use arrays' talk by @Crell at PHPKonf 2021 and a misinterpreted statement that you can save ~50% memory with PHP arrays have triggered intensive research on the topic.

[broadly, a 'seismic' listening technique could help researchers map water movement, moisture levels in soil, with these researchers at Caltech have figured out a way to use vibrations from passing cars to see how much water sits directly beneath the ground’s surface…]

Beyond the Local Void: A comprehensive view on the origins of the Amaterasu particle

I do love that buffer.subarray() returns a – checks notes – Buffer instance, not an array, in Node.js. 
For some reason, Array Modifier was still using Godot 3 in the master branch. From now on, Godot 4 version is the default one ;)

The most powerful cosmic ray since the Oh-My-God particle puzzles scientists
Scientists spot a particle of intense energy, but explaining where it came from might require some new physics.

Discovery of the Amaterasu 240 EeV cosmic ray particle, named after the goddess of the sun in Japanese mythology, by the Telescope Array observatory in Utah. This mysterious event appears to have emerged from the Local Void. Intriguing!

#Excel #dynamic #array #cumulative sum
To calculate a 2-D array where each row is the #cusum of each row in the source table, it’s possible to use the #MMULT function. The #matrix multiplication is done with an upper-right triangular array of 1s. But when you get to 1000 rows, the matrix is a million-cell array, and for 3000 rows or more, #MSExcel is going to go out of memory.
Here is an efficient method of doing this for a dynamic array cusum down columns.
#Excel #dynamic #array #cumulative sum #formulas shootout
https://sysmod.wordpress.com/2023/08/23/excel-dynamic-array-cumulative-sum/
Different methods are evaluated to calculate cumulative sums in a 2D array efficiently. The fastest solution is obtained from a LinkedIn suggestion by Diarmuid Early, and a close second is from Peter Bartholomew.
#cusum
@Isocat
(I have now remembered to use #hashtags for searchability)
To line up alternate rows using formulas, I have to resort to the latest #Excel #dynamic #array #formulas.
=MAKEARRAY(2000,26, LAMBDA(i,j,IF(MOD(i,2)=1, INDEX(Sheet1!A1:Z1000,(i+1)/2,j), INDEX(Sheet2!A1:Z1000,i/2,j) )))
Use the actual rows you have rather than 1000 (and double it for the 2000) and the actual no. columns rather than 26.
To #conditional #format, see the picture.

Did you know that you can get the relative position of every letter of your #canvas text with:
