I lose my love for programming, I watch this man then I'm inlove again(the cycle repeats)

It has been a few years, but I also programmed something like this after watching that video. I had to chuckle when you called it binviz, because I called it binvis

I'm already using nob as my primary build tool for all of my projects, and I am fully prepared to migrate to the final version when it comes out. I've really enjoyed using it so far.

Tsoding is the person I wish I am 😂😂

Such a cool topic, this is my favorite zozin session so far

Really interesting stream. Thanks and keep up with the good work!

12:56 this is the best home folder I've ever seen

1:52:07 you would probably enjoy making yourself a "slugify" command for such scenarios, basically makes any string into an acceptable filename, only thing you'd have to take care of is somehow handling the / character

Thank you so much, the value from your videos is astonishing

Such an interesting topic Zozi, hadnt heard of this at all

You guys are like doing spectrum analyzer for files awesome :)

Very interesting stuff as always! Would love a follow up on this topic

Those patterns make sense for the most part. In sounds, each sample will probably more or less be in a normal distribution, with the highest probability near the center, and smaller probabilities near the extremes. Sound is usually normalized, and it's a wave that crosses zero periodically (127 likely represents 0 in this case). And what we see is that correlations involving two samples in the middle are more often than those involving one or two samples in the extremes. For images, the lines parallel to the major diagonal lines are likely due to pixels involving the same proportions in color components (major diagonal being black to white), so monochromatic gradients. For x86 code, it's really interesting. Vertical and horizontal lines should form when there's some particular value associated to a set of bytes, and when the values in that set only change in the lower bits. As pairs interleave (probably instructions and operands), verticals and horizontals switch for each pair. I think the x86 instruction set encodes registers in the lowest 3 or 4 bits? I don't really know anything about it, but that sounds like something I've seen somewhere. Ascii is the most obvious one. Now, ogg is amazing. My guess is that it has some very frequent bit width in it's encoding, which ends up aligning a lot with byte boundaries, and that's what's causing those squares. But that's not a full explanation, just a general direction in which it could make sense. The compressed files (other than ogg) could be explained by entropy (a good compression should eliminate patterns as much as possible), but I think that's not all of it. I think a bigger reason for not displaying discernible patterns, is because they won't align with byte boundaries: compression schemes typically encode variable width bits. PNG in particular uses some LZ scheme with Huffman encoding iirc. If there are patterns, they'll happen across bytes, and each time appearing in different value positions. Very interesting for sure :)

Apart from where you transition from the end of one row to the beginning of another, it makes a lot of sense that the pattern is diagonal, because images are normally smooth, so the value of one pixel and a neighbouring one is usually not too different (for just an array of pixels anyway, although I guess rgb triplets might be packed next to one another, which could jump?).

Regarding why data looks the way it is: - Executable format lines represent instructions and registers, it is a line because names are usually multiple bytes - Images usually look smooth, thus adjacent bytes are similar and diagonal lines appear - Soundwave data consist of byte sized samples, low value following high value, thus it "sticks" to view sides

Maybe it's time to create a binary format that always looks like Rick Astley when viewed via binviz

after watching your videos, i got back to programming in c for fun.

Hey, that's Derbycon! I'm in Louisville! Wasn't expecting that.

Man, you've a keen mind😂😂. Amazing what you can do with a computer language!!

I think you could have bumped up the base "brightness" of the pixels to make it easier to see the lower values

сэр , спасибо за отличные видео.

Tsoding Daily,which I search Daily for a programming magic.

yet another fucking good recreation programming session

map[y][x] + 1 is a better fit, to omit sub 1 values, edit: also I was thinking maybe normalizing the values by dividing by the squared deviation would make the result less contrasty and remove the overshadowing of the high frequency values

Another way to visualize 3d stuff would be to map the 3rd dimension to a color. That way you don't need a fancy 3d viewer to look at the visualization.

I love you and your awesome content!♥

I use a jetbrains editor and if you make the mistake of opening multiple large repos, you will DEFINITElY run out of memory. when you restart the IDE, it restores your previous work spaces as expected. but instead of indexing just the current window and queuing the rest, it immediately tries to index all the repos you had opened previously. and then i get the popup on mac, running low on memory and everything grinds to a halt

PNG is an interesting one because afaik it's essentially a bitmap inside a GZip archive.

Very cool topic! Ty

"I don't even see the code. All I see is blonde, brunette, red-head."

This is an amazing video, although I can't get the line pattern at all when I tried this out at home (the x64 pattern works fine). I wonder if you used stenography to hide an executable inside an image, would this sort of visualisation technique be able to identify that? Maybe it would just see higher entropy in the picture but no other signs

Reverse engineering is a really interesting field

My sollution for dependencies: just steal the code and fix it yourselves. If you can't fix it yourselves: dismember it and write again. God bless MIT licenses with which you can forget that you steal someones code and you will not be crucified by GNU church or sold on the black market by big corp.

Love this guy ❤

❤ Nice topic

Tsoding poggers as usual

Thank you 😊

I think u could just apply log AFTER you normalize and it would work just fine How ever normalize to a max value of like 10 so that the log curve is actually "used" And you can avoid the none defined 0 by adding a 1 to all the values It doesnt affect the patern much

Very cool stuff. But kind of missing the point on images. Binviz should recognize the file type. In order to recognize image, you need to know its image and read it raw.

as for "why are raw audio files like that?", it's a wave, so the most values will be at the extremes as it slows down and moves to the other side again, where you'll have more values near 0 and 255, as it's a wave and slows down at those points.

Haha, i did this on a text file and only got single pixel lines at the top and left of the image. It turned out the file was coded in UFT-16, so every other byte was just zero ^ -^ Another loss for UTF-16. Great stuff.

My assumption as to why images look the way they do, is because any image element is a run of pixels in an x direction, spanning multiple sections of the same section downward in the y direction. In the output it looks like the byte patterns are shifted right and down, because all images take their origin of 0.0 at the top left corner 🤔

How about training a generative model on this kind of data, then having it generate raw bytes and seeing what they look/sound like, depending on whether the model was trained on images or sounds.

Why not put nob in its own repo and simply use it as a submodule for new projects?

I am really eager to understand THE MATH behind this stuff (to be precise it is probably math statistics) -- any ideas where to start precisely?

8:58 i would love a NN that can guess structures from a multistructured file though. Idk how that would work, though. Like, how to guess when a structure ends and the next begins.

I feel like man pages will produce very specific pattern when doing that shit. Also, thinking while watching video, you probably want to make most popular pixels brighter, while rare hits must have low value, because they are just random hits.

is it possible to use nob's GO_REBUILD_URSELF from the main file instead of a seperate build script?

Why you don't use doom emacs or spacemacs? How row emacs save your time?

1:14:14 - This weirdness in MSVC is true for a bunch of POSIX stuff. They have "stat" as "_stat" and other shite like that. Stupid vendor-locks are stupid.

1:58:10 super smash bros in executable confirmed?

I'm trying to make it 3D and obviously i can't. Any suggestions?

Is there any possibility that You'll create Odysee channel's?

Who needs sha256 if we have file fingerprints like this!

Let's ggoooooo

cheese viz

13:09 Epic scheiße

unfortunately the video has no subtitles :[ I'm not 100% fluent in English 😢

Here is a thought. With a powerful Neural Network it might be possible to reverse this process and produce an executable binary from the image. Lol. And then, we could apply the gaussian diffusion process which is used by midjourney et-al to mix different images based on labels and produce entirely new binary files. Then we could skip the programming and compiling alltogether and simply text-prompt features we want and produce a binary application. I imagine that would be very difficult to program but it certainly seems possible. Good video as always. Cheers.

10:25 why do most c hello worlds use printf("Hello, world ") instead of puts("Hello, world")?

This msvc complex numbers thing is so fucking annoying Every time I need to do something physics related, I need to re implement complex numbers because this stupid msvc I remember my reaction the first time I tried to compile something with c99 complex numbers on msvc and it did not compiled. The sensation I felt, the moment I opened the msvc documentation and saw how the complex numbers works on msvc, is burned on my mind. I still have nightmares about it from time to time

Yeah right, an elite Russian programmer thats "definitely not a hacker". Nice try.

I'm pretty sure your application of log is VERY wrong. You basically set the maximum to the log of itself, while not changing the data in any way. I think the right way to do it would've been to just replace all the numbers with their logs (leave zeros as is).

I start with a like and then every time i see something cool, i dislike and like it again. avg like rate: 7 likes per video. you're welcome

This guy nobs

To claim that there are many programming languages because some company wanted to own some market is, at best, naive and, at worst, stupid. Have some companies tried to own some market by trying to introduce their own version of a language? Yes. But to extrapolate from that is just not valid. Programming languages are tools that often are designed with a specific problem in mind and that has been true all the way from ALGOL, PROLOG, FORTH and LISP up to Rust and Python and the rest of them all.

as someone using modern tools like an IDE... this was so painful to watch. it's like coding on a C64 and calling it productive
