QUESTION
I have a function in my code that loads in the FAT and root directory. This function causes some sort of CPU hang on the PCem emulator but not other emulators like QEMU or PCjs. If this is not a bug with PCem, then why would my program act this way?
The FAT loading function:

QUESTION
I know that the BIOS goes through connected storage devices (floppy disks, CDs, hard drives ... etc) in the order it is configured to (which can be changed in the BIOS settings), looking for the magic 16-bit value (0xAA55) at the end of the first sector of each, and upon finding one it loads (what just became) the boot sector and calls it.
Let's name the device containing the loaded boot sector X. My question is: Instead of looping through all devices, can you identify X and use the BIOS' disk interrupt function to read from it without having to test every connected device? For instance, does BIOS store X's ID somewhere?
Thanks.
P.S. I'm working on an IA-32 machine emulated using BOCHS, I'm always loading from floppy disk #1 so I can hardcode the reading from it, but for the sake of writing clean code and learning I'm asking. I acknowledge that testing all devices is definitely practical.
...ANSWER
Answered 2021-Dec-23 at 10:08When the BIOS passes control to the boot loader it stores "BIOS device ID" in the DL register, so boot loader can just use the device ID it was told to use for all subsequent BIOS functions.
The main problem is that "BIOS device ID" is relatively useless after early boot (after the OS starts using its own disk drivers and stops using BIOS functions); because there's no easy way to determine which device happened to be given which "BIOS device ID"; especially for cases like "RAID 1 mirror" where you might have 2 mostly identical hard drives with mostly identical contents.
I acknowledge that testing all devices is definitely practical.
Heh, no. Install 2 separate copies of the OS on 2 different hard drives (so that you've got 2 boot loaders, one for each copy of the OS) and it becomes impossible for "test all devices" to tell the difference between the OS you booted and the OS you didn't boot.

QUESTION
I created few Box2D rope joints in libGDX. The ropes feel a bit too floppy. How can you make the ropes more stiff? The main Box2D project shows an option for stiffness in their testbed demo:
The rope on the right side shows the desired stiffness:
Does such option exist in libGDX Box2D?
Thats how I create my ropes in libGDX:
ANSWER
Answered 2021-Nov-30 at 15:49If I understood you correctly, you do not like that your rope behaves like rubber or a spring. This has to do with how box2d constraint solver works. For each connection it tries to correct the position of the bodies. Overall, it works out well. But when there are many of connections, it takes time for the solver to put the bodies in correct positions. For this reason, the spring effect arises. To decrease it, you can decrease the simulation time step. This will make the behavior of the connections more accurate, but will increase the CPU utilization. But in your case, it would be best to add another RopeJoint, which would connect the first and the last body of your rope and have a length equal to the length of the rope. This connection will prevent the beginning and end of the rope from moving further than the length of your rope.

I am making a code which takes in jumble word and returns a unjumbled word , the data.json contains a list and here take a word one-by-one and check if it contains all the characters of the word and later checking if the length is same , but the problem is when i enter a word as helol then the l is checked twice and giving me some other outputs including the main one(hello). i know why does it happen but i cant get a fix to it
...ANSWER
Answered 2021-Nov-25 at 18:33As I understand it you are trying to identify all possible matches for the jumbled string in your list. You could sort the letters in the jumbled word and match the resulting list against sorted lists of the words in your data file.

I'm having difficulties with my BBB on CAN communication like for months... I'd be really pleased if you could give me just a little help!
I'm working on CAN protocol between BBB and another CAN device. The another device is confirmed to be working alright with CAN. I'm using my BBB with Cloud9 platform on windows laptop, and on the another device, it's using CAN0.
I have set the 'config-pin' on BBB like below using CAN1, and I tried 'cansend' utility. The bitratre value on the another device is also set to be equal.

QUESTION
Let's say I have built an assembly program (a basic print), so I have got a .BIN file.
Now I want to make it a bootable floppy disc image (a virtual one), so that when I start an OS (in the vm), it will first execute the assembly instructions from my program which is located on that virtual floppy disc.
How to do that correctly?
ANSWER
Answered 2021-Nov-23 at 19:40You can use my boot sector loaders (ldosboot boot.asm for FAT12 / FAT16 FS) and my boot image creation script to make a 1440 KiB file system image preloaded with your kernel executable and a loader in the first sector. You'll also need my macro collection. Here's an example shell session to clone the repos and build an image. This is using hg (Mercurial) to load the repos, wget to get a release of my debugger as an example program, Info-ZIP's unzip to unpack it, NASM to assemble the loader and image, and qemu to run everything once assembled.
