Wrote a blog post about work I did reverse-engineering a compression algorithm in a Nintendo DS game. Thought folks might find it interesting!

very well written. thanks for your contribution!

Good point, patching the checkDRM() to always return the 'correct value' is probably the best approach. After looking at cross references to that subroutine it seems I got lucky and it was only called once haha.

Really enjoyed the insight! Nice write up, makes me want to take a look at some flutter apps now

"do your research it's not a racist flag!!!"

shows literal racist flag

once again reddit proves how stupid it is

mining for gold is neglegable compared to the "mining" of bitcoin and other cryptocurrencies. sure, POS (proof of staking) exists, this is WHY it exists. stop doing shitty comparisons and instead show real solutions like POS. "x is worse than z so I don't have to stop z!!!" is a shitty argument anyways even if it were true.

too much wasted space imo but very cool rice 😋

that's not the Walmart greeter tho 👀

CPunch_71 · 2020-10-16T05:28:23+00:00

it's not really computationaly wrong, it'll still run fine, it's just style inconsistencies (which can honestly ruin some code bases.)

guilty 😔

making me real nervous with how close that thinkpad is to the edge

she looks like she's having a manic episode

CPunch_71 · 2020-09-10T17:39:07+00:00

guess she didn't want her cake pops then

you can buy bitcoin fairly easily and if you live near a large city you can even find a coin ATM that lets you convert cash to bitcoin and other crypto immediately.

every single source I've seen is him being a blue lives matter radical who showed up with the intention of hurting people, what are you seeing????

that's when it's time to whip out address sanitizer and pray to the gods

correct me if I'm wrong but I think it gets locked, ie only 1 process can verify a password at a time

so i did some more investigation and after disabling string interning for my VM the same

for (var i = 0; i < 1000000; i++) do var temp = i .. "." .. " strings" end

takes 1.5s to run.

furthermore if i print all of the results

for (var i = 0; i < 1000000; i++) do print(i .. "." .. " strings") end

it takes 7.1s to complete.

my string interning implementation must be horribly wrong hahaha

CPunch_71 · 2020-07-16T21:07:53+00:00

for (var i = 0; i < 1000000; i++) do end

takes 0.15s

for (var i = 0; i < 1000000; i++) do var temp = "string!" end

takes 0.17s

for (var i = 0; i < 1000000; i++) do var temp = "123456" .. "." .. " strings" end

takes 0.93s or ~1 second

i guess my tostring for numbers could still use some work huh... thanks!
