Byte Code Engineering Library Puns

i.e. I can pass it a protobuf .proto (or similar) style file and generate code, but I get to define how the raw message will look when encoded, which byte will be where etc.

I understand that it wouldn't be able to have all the features of modern message/rpc frameworks, but it would insanely handy when implementing interfaces to closed source systems.

Is there code that makes up what a double, int, or string is? Where would I find it?

#test.c

#include <unistd.h>
#include <ncurses.h>

int main()
{	
     initscr();	
     getch();	
     endwin();	
     sleep(1);	
     return 0;
}

Edit: Fixed the stupid formatting

And sortable based on the numerical values?

eg.:

x := Encode(-11.2)

y := Encode(22.2)

x still less than y and Decode(x) should still equal -11.2

Intuitively, I know that it has something to do with endianess. But my knowledge of it is limited.

Edit: I found this article which helps me understand encoding/binary better: https://www.gobeyond.dev/encoding-binary/

I'm writing a compiler and I would like to generate Java byte code from within Haskell.
My original idea was to generate Java ASM code and execute it on the JVM to generate the files. This seems like a very bad approach.
The alternative is to use a Haskell library for generating byte code. The only one I've found is hs-java although I'm struggling to find any tutorials or documentation of how to use this.
Are there any other libraries that could be used? Otherwise are there any tutorials etc for hs-java?

The context is implementing the packet fragmentation and reassembly scheme used in the ISO_15765-2 communications standard https://en.wikipedia.org/wiki/ISO_15765-2

As a beginner I could be misinterpreting the docs, but the standard Kotlin libraries don't seem to designed for this type of application.

Hey guys! I recently had quite a bit of frustration with manipulating hardware level bytes in MicroPython, so I made my own library, “PyBytes”, to help with it! If any of you have any suggestions or want to help me further develop it, let me know!

GitHub Repository:

https://github.com/dgrantpete/PyBytes

Also us been published to PyPi, so can be installed with “pip install pybytes”

I am new to python, trying to execute below code. I am using python 3.8 Version. Here, i am receiving following error:

Here is my code:

```

import subprocess

curl_command = ("curl -O https://repo1.maven.org/maven2/com/veracode/vosp/api/wrappers/vosp-api-wrappers-java/{}/vosp-api-wrappers-java-{}-dist.zip".format(WrapperVersion, WrapperVersion)).split(" ")

unzip = ("unzip vosp-api-wrappers-java-{}-dist.zip VeracodeJavaAPI.jar".format(WrapperVersion)).split(" ")

process = subprocess.run(curl_command, stdout=subprocess.PIPE, universal_newlines=True, shell=False)

while running the py script with argument, i have received below error. Not sure what's the problem with the code:

```

Over the holidays I wrote a small byte code VM along with a custom byte code and byte code text format. The byte code is stack based and is designed to feel pretty low level. I made a ton of mistakes along the way and had to do a couple of painful refactors, but I'm pretty happy with how it turned out. There are more things I'd like to add to it eventually, but I'm shelving it for now. Check it out and let me know what you think.

Hey there! I'm using Emacs 28.6.0 from flatwhatson pgtk repository. I compiled every elisp code while compilation using make NATIVE_FULL_AOT=1. My Emacs sometimes lag and on idle both of Emacs and Emacs Daemon uses 4-5% CPU. However, while profiler stats shows byte-code is 70% responsible for this load. What is this, can anyone please elaborate.

For Winter 2022, I'm taking an in person class in the Engineering Building and a remote class through PCC. I often can't focus at home (bad home environment), so I'm planning to participate in the remote class as well as do my other studying as needed somewhere on campus.

I commute to campus and am going to have to choose a parking pass for next term. I usually study in the library (I like the atmosphere of being surrounded by books and other people studying), so I was thinking of getting the Parking Structure 1/2/3 permit like I did last term. I heard that the Engineering Building/FAB has student lounges though, so I was thinking of getting the FAB permit so that I can park close to class.

If I buy the FAB permit though, it would be a lot less practical for me to go to the library because of how far away it is. Whichever permit I get, I will be getting a full time permit.

How do the lounges in the Engineering Building / FAB compare to the library for studying and taking a remote class? Is either option better? Would the EB / FAB be good for studying in the evening and during the day?

18th (Terra Byte Café ) and Thompson library (Berry Café) coffee is underrated. Other campus coffee 😒

Is it normal for guys to avoid girls who are studying at the tables as much as possible? I saw some dudes talk about how there were no seats when there were a bunch at a table but some were occupied with 3 girls. Same thing at another table, the guys just turn around and leave the library. Idk just curious 🤕

Over the holidays I wrote a small byte code VM along with a custom byte code and byte code text format. I used Ebiten to give the byte code a way to draw graphics to the screen. The byte code is stack based and is designed to feel pretty low level. I made a ton of mistakes along the way and had to do a couple of painful refactors, but I'm pretty happy with how it turned out. There are more things I'd like to add to it eventually, but I'm shelving it for now. It's not really a game but it was a cool experiment to see how Ebiten can be used for applications other than game development. Check it out and let me know what you think.
