I want to write a C program that will sample something every second (an extension to screen). I can't do it in a loop since screen waits for the program to terminate every time, and I have to access the previous sample in every execution. Is saving the value in a file really my best bet? ...
On one of the applications that I am writing, I was asked to provide the feature for "pencil and eraser" to allow the user to doodle randomly on a document (for proofreading, note-taking, etc.) What would be the best way to store such data? I was thinking of using an image with transparency for each doodle (so that I can also support m...

I'm writing a simple browser based game with a 2d tile map. I'm implementing this map as an HTML table (ok, you can yell at me for using tables later, but it works) with background images. The map could be very very large, but it won't change much, if at all. I could eventually make more maps though. The map cells will not only have a b...

I have an iPhone app that must use external cloud db to sync data between users. Data is structured, so BLOB storage will not do. So far the only alternatives that i see are Amazon SimpleDB MS Azure Storage (Tables). I didnt get if i could use just Storage and no Azure instances. Are there any other similar providers? ...
What is the behavior of various systems when you have more than one copy of a particular program or library running, do string literals get stored once in RAM or once for every copy of the process/library? What if they are stored in an array like: static const char *const foo[] = { "bar", "baz", "buz" }; Does the static change the beh...
Note: This is a follow up to this question. I have a "legacy" program which does hundreds of string matches against big chunks of HTML. For example if the HTML matches 1 of 20+ strings, do something. If it matches 1 of 4 other strings, do something else. There are 50-100 groups of these strings to match against these chunks of HTML (usu...

The title is a bit confusing, so i will explain a bit more using examples. Just a note: i am parsing a file format. Say we have a structure like this: struct example { typeA a; typeB b; typeX x; typeY y; typeZ z; }; So far its ok. Now the problem is, that typeX, typeY and typeZ can vary in size. Depending on flags in th...
I am working in PHP on a Linux server with MySQL. I have a requirement (that I have attempted to talk them out of) to collect credit card information from users so that our company can use the card numbers to hold hotel rooms for a conference. We will not be charging the cards ourselves at all, but instead just sending them to the ho...
I'm creating an app that uses SQLite as a data storage on BlackBerry OS 5.0. When it is removed from a device, I'd like to be diligent and remove the database from the phone. Although I can seem to find out plenty of information on Persistant Storage being removed on the removal of an app, I can't find anything about an SQLite database....

Hello all I am just wondering what's the storage size for an iPad/iPhone app to use? For memory, it is sure that every app can only use 100MB-like memory. How about the storage? I mean the file system in iPad/iPhone app? Use as much as I want until the file system is full? or something like that? ...
[1] states: "When data is deleted from a heap, the data on the page is not compressed (reclaimed). And should all of the rows of a heap page are deleted, often the entire page cannot be reclaimed" "The ALTER INDEX rebuild and reorganize options cannot be used to defragment and reclaim space in a heap (but they can used to defragmen...

Hi, Basically I have two questions. I investigate means of implementing WebDAV interface for EMC ATMOS storage. There will be billion(s) of files with thousands simultanous reads and probably hundreds creations/deletions. The problem is with COPY/MOVE/DELETE operations. If the structure is stored in ATMOS (using namespace interface wh...
