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.

I started implementing some explorations in #Haskell but I had to ditch `data-memocombinators` because #MicroHs doesn't properly support #RankNTypes yet. Instead I'm doing manual #memoization with #array :
```
import Data.Array
-- memoized function, looks up in array
f :: Int -> Int -> Int -> Int
f = \x y z -> if inRange fBounds (x, y, z) then fArray ! (x, y, z) else 0
-- real algorithm, recursive calls use memoized function
f' :: Int -> Int -> Int -> Int
f' 1 1 1 = 1
f' a b c = sum [ f (a - 1) b c, f a (b - 1), f a b (c - 1) ]
-- array, generated with real algorithm
fArray :: Array (Int, Int, Int) [Bool]
fArray = array fBounds [ (i, f' x y z) | i@(x, y, z)<- range fBounds ]
-- array bounds
fBounds :: ((Int, Int, Int), (Int, Int, Int))
fBounds = ((1, 1, 1), (limit, limit, limit))
-- can be as large as necessary for the real problem,
-- but going too big consumes too much memory
limit :: Int
limit = 45

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.

Are these kinds of “convenience methods” in #ECMAScript really necessary? Who have these mainstream #browser vendors consulted and how is array.toSorted() any better than array.slice().sort()?

In my pet project dregen, I iterate an array in Javascript to get pixels from weather data. It felt slow, I measured and got confused. I searched and found several statements supporting my measurements: the historic loop construct
for(let i=0; i<array.length; i++) {
//do stuff with array[i]
}
is faster than the modern constructs
- for(element of array)
- array.forEach(...).
One benchmark: https://stackoverflow.com/a/74674738/2954288
In #PHP, it is annoying when you try to add an #array to a #multidimensional array and it does not work as expected. It turns out that in PHP you must first create each array within the multidimensional array before populating the specific array with items.
You first must do this
$arr = Array();
$arr[1] = Array();
$arr[1][2] = Array();
So that you can then do this
array_push( $arr[1][2], "item" );
PHP should detect all the arrays in your multidimensional array and create them automatically.
I am still pissed off about this from last night.
The array[x][y] syntax for indexing an array inside another array, which is standard in Lua, does not appear to besupported by Pico-8 
I had to make a dummy variable for some
Qiita - 人気の記事 
foo=array[x]
bar=foo[y]
nonsense.
Also, if I used for all i in array, I could not use i to actually index the array. But for i=1,#array do worked fine even though it should be the exact same thing. And it's only as I write this that I realize that it was probably putting each value of the array into i and not the index. But that's fine, there's no method to sort values and I needed to step through them in a specific order, so it's really easiest to just use the numerical index and manually ensure they stay sorted.
And none of this is for any gameplay logic, this is all just the nominally simple code for scrolling that fucking cloud. 
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.
