• Can I prevent IMAP from grabbing files over X mb using PHP?

  - by mike

  I'm building a little script that will connect to an IMAP account and grab the content of the email and also the attachments. It works well for the most part, but when a really large file comes in, it causes the script to time out. Is there any way that I can check the file size before trying to grab it? I think that would be the simplest solution. Otherwise, I may have to upgrade to a server that has more memory.

• Scope of const char*

  - by Neeraj

  Consider this code: const char* someFun() { // ... some stuff return "Some text!!" } int main() { { // Block: A const char* retStr = someFun(); // use retStr } } My question is in the function sumFun() where is "some Text!!", stored (i think may be in some static area in ROM) and what will be its scope? Will the memory pointed by retStr be occupied throughout the program or be released once the block A exits? -- Thanks

• AS3: why is this happening?

  - by Bin Chen

  Hi, I just encounter a strange problem: var a:ClassA = new ClassA; var b:ClassA = a; The program keeps running sometime, the a = null, b = null. The program is a complex one, I am sure that no part will touch a, and b. My question is, will the runtime(garbage collector) to collect the memory of "a" and then assign a and b to null? I am confused, thanks!

• SWI-Prolog: how to load rdf triples using semweb/rdf_db library?

  - by Li Li

  Hi, I have a rdf file (file.trp) in n-triples format, where each line is: "subject predicate object ." I tried to use rdf_load in semweb/rdf_db to load it into memory, but failed. Here is what I tried: ?- rdf_load('file.trp'). ?- rdf_load('file.trp', [format(triples]). the manual says it supports xml and triples. But it only loads rdf xml files. How can I load such rdf triple file? Thanks, Li

• Passing Activity Context to constructors to use internally - is this bad

  - by jax

  Is is bad practice to pass the Context to a constructor and save it as a private variable for internal use? The other option is to pass the Context as a parameter to methods that need it. Which is the better option? I have a feeling that passing to the constructor might result in memory leaks accidentally.

• Processing large (over 1 Gig) files in PHP using stream_filter_*

  - by mike

  $fp_src=fopen('file','r'); $filter = stream_filter_prepend($fp_src, 'convert.iconv.ISO-8859-1/UTF-8'); while(fread($fp_src,4096)){ ++$count; if($count%1000==0) print ftell($fp_src)."\n"; } When I run this the script ends up consuming ~ 200 MB of RAM after going through just 35MB of the file. Running it without the stream_filter zips right through with a constant memory footprint of ~10 MB. What gives?

• How does Java order items in a HashMap or a HashTable?

  - by ComputerJy

  I was wondering how Java sorts items in the Map (HashMap or Hashtable) when they are added. Are the keys sorted by the hashcode, memory reference or by allocation precedence...? It's because I've noticed same pairs in the Map are not always sorted in the same order

  I have a class definition of the form class X { public: //class functions private: A_type *A; //other class variables }; and struct A_type is defined as struct A_type { string s1,s2,s3; }; Inside the constructor, I allocate appropriate memory for A and try A[0].s1="somestring"; It shows segmentation fault. Is this kind of declaration invalid, or am I missing something

• Facebook data collection ethical issues

  - by the_great_monkey

  If I have a Facebook app, and my users agree to allow my app to access their information, photos, friends, etc, is it ethical to grab their information when they log in, and then saving it in memory so that the next time he goes to my app, it can load faster? If so, what about when the user logged off? Is the right thing to do to is to delete all the cached information and photos that the user provided? Has Facebook got any way to detect that we're doing this (saving their information, etc)?

• Java execution details in System.out

  - by John

  As I remember there is a magic command line option in Java that turn on writing of operations that are currently executed to console. The output was looked like byte code. I do not mean -verbose, because it prints only class loading, while this option outputs information like memory allocation etc.

• Efficiently generate numpy array from list comprehension output?

  - by shootingstars

  Is there a more efficient way than using numpy.asarray() to generate an array from output in the form of a list? This appears to be copying everything in memory, which doesn't seem like it would be that efficient with very large arrays. (Updated) Example: import numpy as np a1 = np.array([1,2,3,4,5,6,7,8,9,10]) # pretend this has thousands of elements a2 = np.array([3,7,8]) results = np.asarray([np.amax(np.where(a1 > element)) for element in a2])

• What does it mean to flush a socket?

  - by User4748402

  I don't really know much about sockets except how to read and write to them as if they were files. I know a little about using socket selectors. I don't get why you have to flush a socket, what's actually happening there? The bits just hang out somewhere in memory until they get pushed off? I read some things online about sockets, but it's all very abstract and high level. What's actually happening here?
