Minetest Circuit Challenge - Google CTF 2019 Qualifier 

The video is great! You should make more content on Minetest, I make content for Minetest and Its fun to make tutorials especially, because every view is someone you helped. I am a small RU-vidr, but im not in it for money, I want to show how excellent Minetest is.

warte warte warte.... du bist deutscher?

@@ubuilditmtserver7393 and excellent it is

@@claracrazy Ich bin 12,5% Deutscher, ich spreche etwas Deutsch, aber nicht viel.

is there a render download where i can zoom into the individual logic gates?

i remember playing minetest on ubuntu because minecraft wasn't supported there back then

@@aleksandersats9577 Yeah, I remember when I was I think 11, didn't have the game at the time, shit was epic

Its improvee alot, tons of mods amazing servers. Come back and try it out :D

I remember trying it maybe 5 or 6 years ago... amazed to see how far it's come.

Anyone remember gameboom

Free, and highly customizable!

Great game, check it out. Tons of unique servers

Minecraft at home: open source and built with C++

The default game is committee driven ☹️

At least they didn't fucked up the battle mechanics like mojang did with combat update

How long did it take to do all that by hand?

What he meant by that is the he knew what the goal was (to solve the circuit), he just had to figure out how to implement it. Where as with some other challenges you spend a lot of time researching and tinkering to figure what you even need to do (where is the vulnerability, how can it be exploited, etc.)

surprisingly unsurprisingly simple. hooray!

Bottom line is, LiveOverflow is an intellectual animal. In fact, anyone who can understand this is on another level to me.

parsing in general isnt usually that crazy

I was think that i' m the one that don't understand anything hahaha

@@johnnynakazono6626 I'm confused from your statement.

@@mcruff3 I 'm a confused people, sorry

Same

this video was much easier to understand than his typical stuff. he converted the map into a format that z3 can solve.

Weird fetish but ok

god bless you

Ok fetish weir flex

how do you do it?

@@w花b fetish ok flex weird

1pm

3am for me too lmao

minetest is c++ not java garbage

@@zungaloca java isn't garbage, minecraft is made of garbage code

​@@__jan Java is garbage when come to making games. Minecraft is huge game. No matter how you will write this in Java, it will be slow. Because in Java you cant control memory.

Also depend on if minetest has a command to tick warp (run the simulation without a delay/update limit)

@@zungaloca yes but mods are written in Lua and stuff like mesecons is pretty slow. It doesn't deal well with having a lot of blocks loaded at once either.

Minecraft? When did he play or show minecraft?

@@figboot I didn't say he played Minecraft, I reacted to the part where he said open-source Minecraft clone :)

@@gwentarinokripperinolkjdsf683 mc bedrock bad java edition good

Why Minecraft? The video is about Minetest, they're very different projects with different goals, just an undeniably similar aesthetic on the surface.

just look at minecraft source code and look for possible exploits

lol same knew bits and pieces of programming though.

Mesecons_extended has latcher and flip-flop :D

@RedIAnima YT I was talking about the circuits

oh THHHAAAATS how quantum computers work

Genius

Also known as “Well that sure made things run faster, but look, someone exploited it, patch the microcode and slow everyone’s processors down by 30%”

so basically massively parallel execution

so fucking cringe

you don't nned to learn it an AI will probably beat the best man

have you made an hello world yet? 9 month is enough to make a baby, you probably found some time to make a program ^^

From all the people living on the earth, why your teacher?

@@theoriginyt4869 because coding ??? 🤔🤔🤔

Minetest mod developer here, minetest is great for programming, I have spent a while doing it with multiple different projects. The primary feature it that it uses Lua which is superior in ease of use and single threaded performance to Python.

You can't have wires longer than 15 blocks that don't lose signal unless you use repeaters.

Minecraft doesnt have 1-block logic gates , so it would be hell to parse , also because there's like 10 different designs for every logic gate , and redstone is pretty quirky sometimes , i'd say no unless it is a circuit specifically built for that purpose, or you have A LOT of time in your hands

@@elmegagamer1 not even Minetest does unless you have that mode

@@elmegagamer1 not even Minetest does unless you have that mod

Yeah that was kinda funny

Peki videonun genelinde anlattığı şey detaylı açıklaman mümkün mü

I didn't track time exactly, but probably around 12-16h

@@LiveOverflow Thanks for the reply! Exactly what I was looking for.

Python doesn't have switch statements...

@@karlkastor try { "a": do_a, "b": do_b, "c": do_c }[input](var_to_pass)

Wow that’s an ugly hack :D If you look closely it’s not actually a switch-case. It makes a inline dictionary with function values. And the index will just get the right entry. And call it.

@@LiveOverflow I guess you're right 😂 It is the closest python has to switch statements though, and I've seen it used alot. I personally prefer it to rows of elif.

I imagine it's a lot faster, don't need to have all the unneeded blocks loaded in memory or for the game to run calculations not strictly related to solving it.

pretty much this. I thought i was chugging along well in my programming classes btu wtf is all this. I'm watching defcon videos and now a bunch fo this guys videos and I'm crying. I went into an Info Sec degree btu this guy is on another level. You just have to know much. I can think of the many other jobs i could have done where u need to know far less, and it would have paid just as much or more. Like wtf is this. these videos are just crippling. Even the msot basic warm up challenges on picoCTf, I'm like what. They open shit on a console and connect to servers somhow or shit through console? like what? wtf is goign on. what am i even doing.

Hey, don't be down on yourself. Everyone starts somewhere. Programming is just something to master like everything else. When I first started programming, I didn't understand most of these concepts but now (~6 years later including the yearlong break I took) they're intuitive and natural to me.
