  • Prevent 'Run-time error '7' out of memory' error in Excel when using macro

    - by MasterJedi
    I keep getting this error whenever I run a macro in my excel file. Is there any way I can prevent this? My code is below.

  • Webserver - Memory-bound or CPU-bound? [closed]

    - by JJP
    Possible Duplicate: How do you do Load Testing and Capacity Planning for Web Sites I'm installing a social network using Zend Framework & MySql, with lots of plugins & queries. I want Webserver & Sql server on one box. I'm trying to choose between two machines (on hetzner.de): A) intel i7-2600 3.4 GHz 16 GB DDR3 RAM B) intel i7-920 2.6 GHz 24 GB DDR3 RAM B has 50% more RAM but 30% slower clock speed. Q is: is it obvious where the bottleneck will be? Would I ever need 24GB of RAM, even with lots of concurrent users?

  • Memory Speeds: 1x4GB or 2x2GB? [closed]

    - by Dasutin
    When it comes to speeds what is faster having one 4GB module in your system or having two 2GB modules. I'm not taking in the fact that the system could have dual channel capabilities. Also what about a server environment? Would it be better to have one large, high density module or break it up into several modules for speed and price? I heard an engineer at my office having a discussion with an employee. He said that its better in all situations to have one large capacity modules instead of breaking it up. It would be cheaper and perform faster. He also said it would take longer for the computer to access what it needed if there were more modules instead of having just one. His explanation didn't seem right to me and I thought I would post this question here to see what other people thought.

  • Simple jquery ajax call leaks memory in ie.

    - by Thomas Lane
    I created a web page that makes an ajax call every second. In Internet Explorer 7, it leaks memory badly (20MB in about 15 minutes). The program is very simple. It just runs a javascript function that makes an ajax call. The server returns an empty string, and the javascript does nothing with it. I use setTimout to run the function every second, and I'm using Drip to watch the thing. Here is the source: <html> <head> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load('jquery', '1.4.2'); google.load('jqueryui', '1.7.2'); </script> <script type="text/javascript"> setTimeout('testJunk()',1000); function testJunk() { $.ajax({ url: 'http://xxxxxxxxxxxxxx/test', // The url returns an empty string dataType: 'html', success: function(data){} }); setTimeout('testJunk()',1000) } </script> </head> <body> Why is memory usage going up? </body> </html> Anyone have an idea how to plug this leak? I have a real application that updates a large table this way, but left unattended will eat up Gigabytes of memory. Okay, so after some good suggestions, I modified the code to: <html> <head> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load('jquery', '1.4.2'); google.load('jqueryui', '1.7.2'); </script> <script type="text/javascript"> setTimeout(testJunk,1000); function testJunk() { $.ajax({ url: 'http://xxxxxxxxxxxxxx/test', // The url returns an empty string dataType: 'html', success: function(data){setTimeout(testJunk,1000)} }); } </script> </head> <body> Why is memory usage going up? </body> </html> It didn't seem to make any difference though. I'm not doing anything with the DOM, and if I comment out the ajax call, the memory leak stops. So it looks like the leak is entirely in the ajax call. Does jquery ajax inherently create some sort of circular reference, and if so, how can I free it? By the way, it doesn't leak in Firefox. Someone suggested running the test in another VM and see if the results are the same. Rather than setting up another VM, I found a laptop that was running XP Home with IE8. It exhibits the same problem. I tried some older versions of jquery and got better results, but the problem didn't go away entirely until I abandoned ajax in jquery and went with more traditional (and ugly) ajax.

  • Python: Memory usage and optimization when modifying lists

    - by xApple
    The problem My concern is the following: I am storing a relativity large dataset in a classical python list and in order to process the data I must iterate over the list several times, perform some operations on the elements, and often pop an item out of the list. It seems that deleting one item out of a Python list costs O(N) since Python has to copy all the items above the element at hand down one place. Furthermore, since the number of items to delete is approximately proportional to the number of elements in the list this results in an O(N^2) algorithm. I am hoping to find a solution that is cost effective (time and memory-wise). I have studied what I could find on the internet and have summarized my different options below. Which one is the best candidate ? Keeping a local index: while processingdata: index = 0 while index < len(somelist): item = somelist[index] dosomestuff(item) if somecondition(item): del somelist[index] else: index += 1 This is the original solution I came up with. Not only is this not very elegant, but I am hoping there is better way to do it that remains time and memory efficient. Walking the list backwards: while processingdata: for i in xrange(len(somelist) - 1, -1, -1): dosomestuff(item) if somecondition(somelist, i): somelist.pop(i) This avoids incrementing an index variable but ultimately has the same cost as the original version. It also breaks the logic of dosomestuff(item) that wishes to process them in the same order as they appear in the original list. Making a new list: while processingdata: for i, item in enumerate(somelist): dosomestuff(item) newlist = [] for item in somelist: if somecondition(item): newlist.append(item) somelist = newlist gc.collect() This is a very naive strategy for eliminating elements from a list and requires lots of memory since an almost full copy of the list must be made. Using list comprehensions: while processingdata: for i, item in enumerate(somelist): dosomestuff(item) somelist[:] = [x for x in somelist if somecondition(x)] This is very elegant but under-the-cover it walks the whole list one more time and must copy most of the elements in it. My intuition is that this operation probably costs more than the original del statement at least memory wise. Keep in mind that somelist can be huge and that any solution that will iterate through it only once per run will probably always win. Using the filter function: while processingdata: for i, item in enumerate(somelist): dosomestuff(item) somelist = filter(lambda x: not subtle_condition(x), somelist) This also creates a new list occupying lots of RAM. Using the itertools' filter function: from itertools import ifilterfalse while processingdata: for item in itertools.ifilterfalse(somecondtion, somelist): dosomestuff(item) This version of the filter call does not create a new list but will not call dosomestuff on every item breaking the logic of the algorithm. I am including this example only for the purpose of creating an exhaustive list. Moving items up the list while walking while processingdata: index = 0 for item in somelist: dosomestuff(item) if not somecondition(item): somelist[index] = item index += 1 del somelist[index:] This is a subtle method that seems cost effective. I think it will move each item (or the pointer to each item ?) exactly once resulting in an O(N) algorithm. Finally, I hope Python will be intelligent enough to resize the list at the end without allocating memory for a new copy of the list. Not sure though. Abandoning Python lists: class Doubly_Linked_List: def __init__(self): self.first = None self.last = None self.n = 0 def __len__(self): return self.n def __iter__(self): return DLLIter(self) def iterator(self): return self.__iter__() def append(self, x): x = DLLElement(x) x.next = None if self.last is None: x.prev = None self.last = x self.first = x self.n = 1 else: x.prev = self.last x.prev.next = x self.last = x self.n += 1 class DLLElement: def __init__(self, x): self.next = None self.data = x self.prev = None class DLLIter: etc... This type of object resembles a python list in a limited way. However, deletion of an element is guaranteed O(1). I would not like to go here since this would require massive amounts of code refactoring almost everywhere.

  • Basic C question, concerning memory allocation and value assignment

    - by VHristov
    Hi there, I have recently started working on my master thesis in C that I haven't used in quite a long time. Being used to Java, I'm now facing all kinds of problems all the time. I hope someone can help me with the following one, since I've been struggling with it for the past two days. So I have a really basic model of a database: tables, tuples, attributes and I'm trying to load some data into this structure. Following are the definitions: typedef struct attribute { int type; char * name; void * value; } attribute; typedef struct tuple { int tuple_id; int attribute_count; attribute * attributes; } tuple; typedef struct table { char * name; int row_count; tuple * tuples; } table; Data is coming from a file with inserts (generated for the Wisconsin benchmark), which I'm parsing. I have only integer or string values. A sample row would look like: insert into table values (9205, 541, 1, 1, 5, 5, 5, 5, 0, 1, 9205, 10, 11, 'HHHHHHH', 'HHHHHHH', 'HHHHHHH'); I've "managed" to load and parse the data and also to assign it. However, the assignment bit is buggy, since all values point to the same memory location, i.e. all rows look identical after I've loaded the data. Here is what I do: char value[10]; // assuming no value is longer than 10 chars int i, j, k; table * data = (table*) malloc(sizeof(data)); data->name = "table"; data->row_count = number_of_lines; data->tuples = (tuple*) malloc(number_of_lines*sizeof(tuple)); tuple* current_tuple; for(i=0; i<number_of_lines; i++) { current_tuple = &data->tuples[i]; current_tuple->tuple_id = i; current_tuple->attribute_count = 16; // static in our system current_tuple->attributes = (attribute*) malloc(16*sizeof(attribute)); for(k = 0; k < 16; k++) { current_tuple->attributes[k].name = attribute_names[k]; // for int values: current_tuple->attributes[k].type = DB_ATT_TYPE_INT; // write data into value-field int v = atoi(value); current_tuple->attributes[k].value = &v; // for string values: current_tuple->attributes[k].type = DB_ATT_TYPE_STRING; current_tuple->attributes[k].value = value; } // ... } While I am perfectly aware, why this is not working, I can't figure out how to get it working. I've tried following things, none of which worked: memcpy(current_tuple->attributes[k].value, &v, sizeof(int)); This results in a bad access error. Same for the following code (since I'm not quite sure which one would be the correct usage): memcpy(current_tuple->attributes[k].value, &v, 1); Not even sure if memcpy is what I need here... Also I've tried allocating memory, by doing something like: current_tuple->attributes[k].value = (int *) malloc(sizeof(int)); only to get "malloc: * error for object 0x100108e98: incorrect checksum for freed object - object was probably modified after being freed." As far as I understand this error, memory has already been allocated for this object, but I don't see where this happened. Doesn't the malloc(sizeof(attribute)) only allocate the memory needed to store an integer and two pointers (i.e. not the memory those pointers point to)? Any help would be greatly appreciated! Regards, Vassil

  • Upgrading TFS 2005 to TFS 2010 fails at "Executing servicing step Upgrade Version Control Identities"

    - by nadeemmar
    Hi all, I have been trying to upgrade our TFS 2005 to TFS 2010 but with no luck so far. I went through the TFS Installation guide and many upgrade guides but with no luck in overcoming the issue I am facing which seems to be unique and different to other described issues. In our company, we have a domain forest with several domains. Lets say domain A, B, and C. TFS is in domain A and has users from all these three domains. All domains have trust reltionships between them. However, domain C was deleted several months ago. In the upgrade process, whenever I reach the collection upgrade step, the following error is raised: [Info @09:57:50.997] [2010-12-29 09:55:47Z][Informational] Step Data: ExtensionType = Microsoft.TeamFoundation.VersionControl.Server.PlugIns.WorkspaceSecurityNamespaceExtension [Info @09:57:50.997] [2010-12-29 09:55:47Z] Servicing step Create VersionControl Security Namespaces passed.

With a bit of googling, I figured out that TFSConfig Identities command can be used to remap users from one domain to the other. I went ahead and created local users that matches the users we have from domain C and ran the TFSConfig Identities /Change command and it executed successfully. However, I still get the same error. I am stuck and can't figure out how to move forward :( I need your expertise, has anyone faced this issue before? Do I need to change these identities on TFS 2005 before I commence the upgrade? I forgot to mention, I am following the upgrade with a move approach. I created a virtual machine for testing the upgrade. Installed SQL server 2008, restored the TFS databases and installed TFS 2010 and ran the upgrade wizard. Regards, Nadeem

  • Does any upgrade version of Visual Studio require an installed development tool?

    - by Will Eddins
    I'm wondering this from a legal standpoint and an installation-issue standpoint. I'm considering pre-ordering Visual Studio 2010 for future use in some home projects, and you cannot pre-order a full version, only an upgrade version. On the preorder page, it says: Eligible for upgrade with any previous version of Visual Studio or any other developer tool. In reality, I think it won't require anything installed, but from a legal standpoint, is this inclusive with development tools such as Eclipse? After installing Windows 7 on this PC, Eclipse is currently the only IDE I have installed. But really anything could be considered a developer tool, such as Notepad++ or Kaxaml. How has this worked in regards to previous upgrade versions?

    I had an XP system - formatted the HD then ran Windows 8 Upgrade install. Install was fine. It cannot activate and gives me the 'this is an upgrade' error. Is there ANY way to fix this (MS Support call or something?) before I scrap the entire Windows 8 install, Reinstall XP, then upgrade to Windows 8 the proper way? I hate to waste the day's worth of config-the-new-os time if not absolutely necessary. Error was the 0XC004F061 from Windows 8.

  • How Will Mac OS X Snow Leopard Upgrade Work?

    - by Blaenk
    I am relatively new to Mac OS X. I got my MacBook in January, and I have never experienced a new version of the operating system. I am wondering if I should simply upgrade my install to Snow Leopard. I come from Windows where it is advised to do a complete reformat. I would rather not do this, however, and I have a feeling that due to Mac OS X' POSIX based nature, it might actually not be all that bad if I upgrade. I guess if things end up screwing up I can simply go ahead and reformat, but I am wondering what it is like to upgrade systems running Mac OS X. I wouldn't want my Snow Leopard installation to be somehow deficient due to certain inconsistencies within the system.

  • In place SQL 2008 upgrade vs. Side by side?

    - by Jim
    I have a SQL 2005 Std edition server with 5 databases in production, 4 db's are used by web-based apps the 5th is a desktop application. My question is should I perform an in-place upgrade or a side-by-side by creating an sql2008 instance on the same box? The machine is a VM on vmware and I'm planning on taking a snapshot before the upgrade and having a 'blackout' window during the upgrade so that I could roll back to the snapshot if things go really bad. Any previous experience and advice is appreciated.

  • UIImagePickerController Memory Leak

    - by Watson
    I am seeing a huge memory leak when using UIImagePickerController in my iPhone app. I am using standard code from the apple documents to implement the control: UIImagePickerController* imagePickerController = [[UIImagePickerController alloc] init]; imagePickerController.delegate = self; if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) { switch (buttonIndex) { case 0: imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera; [self presentModalViewController:imagePickerController animated:YES]; break; case 1: imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; [self presentModalViewController:imagePickerController animated:YES]; break; default: break; } } And for the cancel: -(void) imagePickerControllerDidCancel:(UIImagePickerController *)picker { [[picker parentViewController] dismissModalViewControllerAnimated: YES]; [picker release]; } The didFinishPickingMediaWithInfo callback is just as stanard, although I do not even have to pick anything to cause the leak. Here is what I see in instruments when all I do is open the UIImagePickerController, pick photo library, and press cancel, repeatedly. As you can see the memory keeps growing, and eventually this causes my iPhone app to slow down tremendously. As you can see I opened the image picker 24 times, and each time it malloc'd 128kb which was never released. Basically 3mb out of my total 6mb is never released. This memory stays leaked no matter what I do. Even after navigating away from the current controller, is remains the same. I have also implemented the picker control as a singleton with the same results. Here is what I see when I drill down into those two lines: Any help here would be greatly appreciated! Again, I do not even have to choose an image. All I do is present the controller, and press cancel. Update 1 I downloaded and ran apple's example of using the UIIMagePickerController and I see the same leak happening there when running instruments (both in simulator and on the phone). http://developer.apple.com/library/ios/#samplecode/PhotoPicker/Introduction/Intro.html%23//apple_ref/doc/uid/DTS40010196 All you have to do is hit the photo library button and hit cancel over and over, you'll see the memory keep growing. Any ideas? Update 2 I only see this problem when viewing the photo library. I can choose take photo, and open and close that one over and over, without a leak.

  • Can immutable be a memory hog?

    Let's say we have a memory-intensive class like an Image, with chainable methods like Resize() and ConvertTo(). If this class is immutable, won't it take a huge amount of memory when I start doing things like i.Resize(500, 800).Rotate(90).ConvertTo(Gif), compared to a mutable one which modifies itself? How to handle a situation like this in a functional language?
