I have a flash memory stick which according to GParted is "unallocated". As such it does not appear in File Browser or Gnome terminal. How can I get it to function? I don't mind formatting it but it is not showing. GParted will not let me change anything.

I am writing a game in C with SDL. I can successfully display one image on the screen and animate it. However, I am having a lot of issues getting the background to display using the same method. I was asking for help on SDL related forums, but I determined that the issue is not SDL related, and it is actually a pointer issue. However, I can't find where I'm going wrong.
Code:
#include <SDL/SDL.h>
struct image

alloc_task_struct( ) This function allocates 8 KB task_union memory areas. The function takes memoryareas from the cacheif it is at least half-full or if there isn't a free pair of consecutive page frames available.

I've just installed ubuntu 10.04 on a Lenovo Thinkpad Edge. Problem is that it generally doesn't detect the USB memories that I've been trying to use. On two occasions it did in fact detect the flash memory, but it couldn't open/read it for some reason (USB memories works on other computers), but all the other times the USB flash memory didn't even show up in Nautilus.
I am no techie so I'm not sure how to check what the problem is here. I've been googling it but either it refers to some specific stuff that doesn't cover my case or it simply is too technical for average users like me to understand.

How should you unmount the USB, and maybe even how do I get my data back?
View 7 Replies View RelatedUsing 10.04 Netbook version. I am finding on my Asus EEE 901 that sometimes file copy just seems to freeze - seems to happen usually when copying from the built-in SSD memory to the plug-in SDHC memory card. I have tried reformatting the card and using a different card. It is not just this computer since I found the same thing on my last Asus which was the 900 model.
I am told that there are issues with Nautilus. Is there anything which can be done to improve this or is there anything else which I can install besides Nautilus? I am assuming that there is some issue related to Ubuntu's handling of SDHC memory cards.
It is becoming annoying because it seems to work sometimes and then not. When it happens only option seems to be to turn the netbook off and on again. Even if the file copy is cancelled the card seems to be unaccesible until rebooted.
Also after a certain point it seems that when I try and copy new files to the card, they appear to copy ok but obviously are corrupt in some way - when you try to play videos for instance they are faulty.

how to calculate (if possible) the end address of an image file in a flash memory.

I kinda need the end address, sad thing is, I don't know how to calculate it.test.img's start address is 0, the size is 0x20000 and consumes 3 sectors.

View 2 Replies View RelatedI used to be able to write to my SD memory card but just recently it is being automatically mounted as read-only. I checked the read-only tab and tried to set it to the lock position, and to the unlock position. Neither position makes a difference. It was working normally a few days ago. I also tried changing the permission using su
ls -lt gives the following result

chmod chgrp and chown in su mode don't change anything either.

I am doing some Linux kernel programming for my research project. I need to record the timestamp (by using cpuid and rdtsc) when an interrupt handler (top half) is first invoked. Due to the time critical nature of the problem itself, I have to do the timestamping inside the interrupt handler itself (the first operation when the handler is called). However, I understand that tasks that are not so time critical should be deferred to a tasklet function (bottom half) for processing because other interrupts are disabled in a (top-half) interrupt handler. I am currently out of idea on how I can pass the timestamp information that I have obtained in the interrupt handler to the corresponding tasklet function.
View 2 Replies View RelatedRAM for older machines like I use is fairly cheap these days. But flash memory is just as cheap or cheaper. So I'd like to ask about the feasibility of expanding my system's memory using flash memory. And about whether creating a partition for swap on the flash memory, or whether a swap file on the flash device, is the better way to go.
By flash memory I have in mind mainly USB sticks or what are sometimes called "pen drives." But I do also have CF and SD cards that, with the proper cheap adapter (one of which I already own for adapting CF) could be used to create extra swap space. So, what is the current consensus on the feasibility/advisability of using flash memory for swap? I've read about the limited write cycles of flash being an argument against using it for swap. But recent reading indicates to me that the limited write cycles problem applies mostly to older, smaller-capacity flash memory. Some will come out and say that, for larger-capacity flash memory, the life of the device is likely to exceed the amount of time your current computer will be useful (I think I've seen estimates in the range of 3-4 years life--minimum--for newer, higher-capacity flash memory).
A more persuasive argument I've heard against using flash memory for swap is that access times for these devices can be much slower than SATA, and maybe even IDE, hard drives. That would certainly dictate against using flash memory for swap.
So, how about some input on this issue? Anyone using flash memory for swap? If so, what kind (e.g., usb stick or SD/CF)? Are you using a swap file or a swap partition? How's system performance? Likewise, has anyone had flash-memory-used-as-swap die on them? The consequences would undoubtedly be dire. Also, has anyone measured flash memory access times to confirm or refute claims about slow access times? Are some types of flash memory better/worse than others in terms of access times?
I'm currently using OpenSuse 11.1 web server. This is bad since 11.1 is no longer supported. the reason why I am using it is because Function set_magic_quotes_runtime() was no longer being used. (so I was told)
That being said, is there a way to get Function set_magic_quotes_runtime() to function on the newer versions of OpenSuSE?
the function terminates if no key is pressed for 10 consecutive seconds. I tried using the -t option as suggested in some forums, but my version of showkey doesn't have the option of changing the timeout. The options I get are:
-h --helpdisplay this help text
-a --asciidisplay the decimal/octal/hex values of the keys
-s --scancodesdisplay only the raw scan-codes
-k --keycodesdisplay only the interpreted keycodes (default).
Is it possible to write a script to use this function and still keep the function active until an interrupt is recieved?
I am trying to install Ubuntu 10.10 from a USB flash memory stick. It works fine until around 95%, where I get the following warning/error:
[Code]....
I click OK and the installer seems to finish nicely, except the terminal throws several errors along these lines (see photo):
[Code]....
I tried also with 10.04 LTS, the difference being that the install warning appears two or three times instead of once. Some results from googling (Ubuntu Forums, Ubiquity bug) suggest unchecking the initial update options. I am going to try this but I'm not sure if I'll be able to get the boot loader right (there seemed to be problems with this).
