Exceptions & Interrupts
When I was searching for a distinction between Exceptions and Interrupts, I found this question Interrupts and exceptions on SO... Some answers there were not suitable (at least for assembly level): "Exception are software-version of an interrupt" But there exist software interrupts!! "Interrupts are asynchronous but exceptions are s...
How can I interrupt a ServerSocket accept() method?
Hi, In my main thread I have a while(listening) loop which calls accept() on my ServerSocket object, then starts a new client thread and adds it to a Collection when a new client is accepted. I also have an Admin thread which I want to use to issue commands, like 'exit', which will cause all the client threads to be shut down, shut its...
How to stop the execution of Java program from Command line?
My main field is .Net but recently I have got something to do with Java. I have to create a shell utility in Java that could run in background reading few database records after specified duration and do further processing. It's a kind of scheduler. Now I have few concerns: How to make this work as a service. I want to execute it throug...
Catching / blocking SIGINT during system call
I've written a web crawler that I'd like to be able to stop via the keyboard. I don't want the program to die when I interrupt it; it needs to flush its data to disk first. I also don't want to catch KeyboardInterruptedException, because the persistent data could be in an inconsistent state. My current solution is to define a signal h...
Interrupt №13 (ah=48) - not working
I want fetch the parameters of my hard disk. Using the technique described here. This is code showing normal parameters of floppy disk: mov dl,00h mov ah,08h int 13h This is code, showing not valid parameters of hard disk (may be, my hard disk space is big (LBA)): mov dl,80h mov ah,08h int 13h And I've written this code: mov dl,...
Problem with stack based implementation of function 0x42 of int 0x13
I'm trying a new approach to int 0x13 (just to learn more about the way the system works): using stack to create a DAP.. Assuming that DL contains the disk number, AX contains the address of the bootable entry in PT, DS is updated to the right segment and the stack is correctly set, this is the code: push DWORD 0x00000000 add ax, 0x00...

what is the likely cause of CMOS_WRITE failing to work?
I've been puzzled by a RTC problem for several days: i couldn't write to the RTC register. Following is the code snippet and the value I read from the reg(last line) is always different from what i just wrote to the reg. Anyone can help me understand this ? val = CMOS_READ(RTC_FREQ_SELECT); printk(KERN_INFO "reading val=%d from...
Polling and interrupt based methods for packet processing in multicore processor
This query is related with the packet processing in multicore processors. Packet processing can be either in Linux or pure datapath. Is it true that if the packet processing application is on Linux, then it must be interrupt based processing of packets for high performance, but if the packet processing is in pure datapath (without linux)...

How to write interruptable methods
I have a method which, conceptually, looks something like: Object f(Object o1) { Object o2 = longProcess1(o1); Object o3 = longProcess2(o2); return longProcess3(o3); } Where the processes themselves might also be compound: Object longProcess1(Object o1) { Object o2 = longSubProcess1(o1); return longSubProcess2(o2)...
Basic NES Emulation theory - I'm stuck
In advance, I apologize for the open endedness, and general wishy-washiness of this question, because to be honest my knowledge of the topic is very patchy and I'm finding it hard to even describe my problem. I really didn't want to post, but I'm completely and utterly stuck. I have started a NES emulator. It's interpreted (so no dynami...

Do Browsers cause Interrupts to their JS when receiving a response?
Assume, for whatever reason, that we have three inline scripts on a page. Each of these scripts are functionally the same, and all three will create a script tag, with the source set to a server-side script (each with slightly different parameters) which returns JS to execute. Assume this JS contains a global variable containing importan...
