• virtual host setup: can't access wordpress site without www

  - by two7s_clash

  I would like to access my site both with and without using the www. Currently it only works with. Leaving out the www just goes to a blank page. Also, wp-admin just loads a blank page too. I have set an A record for mysite.com and www.mysite.com, both pointing to my static Bitnami IP. I also have a subdomain mapped to another directory that is working just fine (conference.mysite.com and www.conference.mysite.com). I'm using a Bitnami stack on an AWS EC2 micro instance.

• Just a few questions about Hyper-V virtual machines and clustering

  - by René Kåbis

  I have been using Microsoft’s Hyper-V technology for a little while now, but I am just now dipping my toe into clustering. In particular, I am trying to implement a fault-tolerant SQL DB. This involves setting up two VMs, clustering them via Failover Cluster, and then installing SQL Server in some fashion. I have two physical machines - one high-end and rather beefy “heavy lifter” to contain the majority of the VMs, and another “backup” (a repurposed desktop) to hold the essential “secondary” (or failover) AD-DC, SQL and FS VMs. The main reason why I find the failover cluster at the VM level so attractive is that it presents a single IP and DNS entry to the network as a whole - if one machine (physical or virtual) goes down, you might loose some ping and the connections get reset, but the network applications (Microsoft RMS connection to backend SQL) can still connect to a viable DB without having to mess around with the settings at all. My first question is in terms of SQL Server itself. If I have a cluster between two VMs, does it make more sense to install the SQL Server in Failover Cluster configuration or should I simply install it in a stand-alone config and mirror the DBs? For example, this post suggests just mirroring the DBs, but do I just mirror standalone DBs on standalone VMs, or can I get the network and failover benefits of clustered VMs while still utilizing (on each clustered VM) standalone DBs that have been mirrored between each other? As well, I have come across a lot of documentation about SQL clustering, but most assume a number (#2) of physical machines to hold not only the actual SQL VMs but also the Quorum and Witness stores. I will not be able to muster more than two physical machines. As such, I will have to be satisfied with a VM cluster that does not exceed two VMs (one for each physical machine). Another issue involves MSDTC - the Distributed Transaction Coordinator. When attempting to install the SQL Failover Cluster (I never completed it for this reason) it threw a hissy fit because MSDTC had not been clustered. Search as I might, I have not yet found a way to do so under Windows Server 2012 R2. I have found plenty of docs for Windows 2008 and 2008 R2, but these instructions don’t align with 2012 R2 (at least, not in a way that allows me to successfully cluster MSDTC). Plus, some of the instructions that I have found for SQL Server Failover Cluster installation suggest that a third “network device” - shared network storage (a SAN) - is required for the DB itself (and other functionality). I do not have this, and won’t be getting this. Most of my storage exists on the “heavy lifter” that was designed for all of the “primary” VMs. If that physical machine goes down, so does the storage. The secondary server does have enough resources for an AD-DC Server, an SQL server and a File Server, so it will handle the “secondary” failover versions of those VMs (clustered or not). My final question involves file servers. If I cluster file servers between two VMs (one on my “heavy lifter” and another on my “backup”, how do I mirror the data between them? Clustering VMs only provides a single point of access on the network for a resource, it doesn’t exactly replicate data between the two - that is left to the services that serve up that data. I am unsure how I can ensure that file server data between two clustered file server VMs can be properly mirrored. Remember, I only have two devices to be used here - my primary machine and a backup secondary. There is no chance of me obtaining a SAN or any other type of network attached storage. What exists on the machines must act as the storage. Thanks in advance for any suggestions.

• UIImagePickerController Save to Disk then Load to UIImageView

  - by Harley Gagrow

  Hi, I have a UIImagePickerController that saves the image to disk as a png. When I try to load the PNG and set a UIImageView's imageView.image to the file, it is not displaying. Here is my code: (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage]; NSData *imageData = UIImagePNGRepresentation(image); // Create a file name for the image NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setTimeStyle:NSDateFormatterShortStyle]; [dateFormatter setDateStyle:NSDateFormatterShortStyle]; NSString *imageName = [NSString stringWithFormat:@"photo-%@.png", [dateFormatter stringFromDate:[NSDate date]]]; [dateFormatter release]; // Find the path to the documents directory NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; // Now we get the full path to the file NSString *fullPathToFile = [documentsDirectory stringByAppendingPathComponent:imageName]; // Write out the data. [imageData writeToFile:fullPathToFile atomically:NO]; // Set the managedObject's imageLocation attribute and save the managed object context [self.managedObject setValue:fullPathToFile forKey:@"imageLocation"]; NSError *error = nil; [[self.managedObject managedObjectContext] save:&error]; [self dismissModalViewControllerAnimated:YES]; } Then here is how I try to load it: self.imageView.backgroundColor = [UIColor lightGrayColor]; self.imageView.frame = CGRectMake(10, 10, 72, 72); if ([self.managedObject valueForKey:@"imageLocation"] != nil) { NSLog(@"Trying to load the imageView with: %@", [self.managedObject valueForKey:@"imageLocation"]); UIImage *image = [[UIImage alloc] initWithContentsOfFile:[self.managedObject valueForKey:@"imageLocation"]]; self.imageView.image = image; } else { self.imageView.image = [UIImage imageNamed:@"no_picture_taken.png"]; } I get the message that it's trying to load the imageView in the debugger, but the image is never displayed in the imageView. Can anyone tell me what I've got wrong here? Thanks a bunch.

• Security strategies for storing password on disk

  - by Mike

  I am building a suite of batch jobs that require regular access to a database, running on a Solaris 10 machine. Because of (unchangable) design constraints, we are required use a certain program to connect to it. Said interface requires us to pass a plain-text password over a command line to connect to the database. This is a terrible security practice, but we are stuck with it. I am trying to make sure things are properly secured on our end. Since the processing is automated (ie, we can't prompt for a password), and I can't store anything outside the disk, I need a strategy for storing our password securely. Here are some basic rules The system has multiple users. We can assume that our permissions are properly enforced (ie, if a file with a is chmod'd to 600, it won't be publically readable) I don't mind anyone with superuser access looking at our stored password Here is what i've got so far Store password in password.txt $chmod 600 password.txt Process reads from password.txt when it's needed Buffer overwritten with zeros when it's no longer needed Although I'm sure there is a better way.

• Storing large numbers of varying size objects on disk

  - by Foredecker

  I need to develop a system for storing large numbers (10's to 100's of thousands) of objects. Each object is email-like - there is a main text body, and several ancillary text fields of limited size. A body will be from a few bytes, to several KB in size. Each item will have a single unique ID (probably a GUID) that identifies it. The store will only be written to when an object is added to it. It will be read often. Deletions will be rare. The data is almost all human readable text so it will be readily compressible. A system that lets me issue the I/Os and mange the memory and caching would be ideal. I'm going to keep the indexes in memory, using it to map indexes to the single (and primary) key for the objects. Once I have the key, then I'll load it from disk, or the cache. The data management system needs to be part of my application - I do not want to depend on OS services. Or separately installed packages. Native (C++) would be best, but a manged (C#) thing would be ok. I believe that a database is an obvious choice, but this needs to be super-fast for look up and loading into memory of an object. I am not experienced with data base tech and I'm concerned that general relational systems will not handle all this variable sized data efficiently. (Note, this has nothing to do with my job - its a personal project.) In your experience, what are the viable alternatives to a traditional relational DB? Or would a DB work well for this?

• OS X won't boot up unless I hold down option key

  - by Gazzer

  I have a strange issue on an early 2008 Mac Pro running OS 10.6: if I restart the computer it restarts normally if I shutdown and boot, it stops at the grey screen just before the boot process if I shutdown and boot but hold down the option key, I can select the boot disk and all is good. I've just cloned the disk, and the same thing happens. The disk is a SAMSUNG HD154UI The disk is partitioned (the second partition holds a clone of the Snow Leopard Install disk) One weird thing on the original disk was one of the partitions said 'EFI Boot' in a non-aliased font rather than the name of the disk when the disks are listed upon holding down option. Solution: it seems that there was a problem with the disk. Part of the difficulty in finding the solution was that you need to remove the disk from the computer completely. For example, a good disk in Bay 3, wouldn't boot up if the bad disk was in Bay 2. So for ages I thought the problem was hardware related in Bay 3. So if you think you have a dodgy disk remove it totally if you are testing the hardware with a 'clean' disk. Cleaning the PRAM helped to get the new disk to work too.

• GNU/Linux swapping blocks system

  - by Ole Tange

  I have used GNU/Linux on systems from 4 MB RAM to 512 GB RAM. When they start swapping, most of the time you can still log in and kill off the offending process - you just have to be 100-1000 times more patient. On my new 32 GB system that has changed: It blocks when it starts swapping. Sometimes with full disk activity but other times with no disk activity. To examine what might be the issue I have written this program. The idea is: 1 grab 3% of the memory free right now 2 if that caused swap to increase: stop 3 keep the chunk used for 30 seconds by forking off 4 goto 1 - #!/usr/bin/perl sub freekb { my $free = `free|grep buffers/cache`; my @a=split / +/,$free; return $a[3]; } sub swapkb { my $swap = `free|grep Swap:`; my @a=split / +/,$swap; return $a[2]; } my $swap = swapkb(); my $lastswap = $swap; my $free; while($lastswap >= $swap) { print "$swap $free"; $lastswap = $swap; $swap = swapkb(); $free = freekb(); my $used_mem = "x"x(1024 * $free * 0.03); if(not fork()) { sleep 30; exit(); } } print "Swap increased $swap $lastswap\n"; Running the program forever ought to keep the system at the limit of swapping, but only grabbing a minimal amount of swap and do that very slowly (i.e. a few MB at a time at most). If I run: forever free | stdbuf -o0 timestamp > freelog I ought to see swap slowly rising every second. (forever and timestamp from https://github.com/ole-tange/tangetools). But that is not the behaviour I see: I see swap increasing in jumps and that the system is completely blocked during these jumps. Here the system is blocked for 30 seconds with the swap usage increases with 1 GB: secs 169.527 Swap: 18440184 154184 18286000 170.531 Swap: 18440184 154184 18286000 200.630 Swap: 18440184 1134240 17305944 210.259 Swap: 18440184 1076228 17363956 Blocked: 21 secs.

I have the feeling it is related to the swapping issue, but I cannot tell for sure. My first idea was to tweak /proc/sys/vm/swappiness from 60 to 0 or 100, just to see if that had any effect at all. 0 did not have an effect, but 100 did cause the problem to arise less often. How can I prevent the system from blocking for such a long time? Why does it decide to swapout 1-3 GB when less than 10 MB would suffice?

• Base URL in ASP.net Master Pages with virtual Directories

  - by Ian

  Hi All, I have an ASP.net master page. In this master, I have all my css and javascript files defined. I also have a few images and a few buttons and hyperlinks. All the urls are all declared as relative ie "/scripts/ian.js" Everything works fine if this site is the root website, but I need it to work in a virtual directory. My problem is when I place this website in a virtual directory under a root site, all my links are pointing to the root site. so my links point to www.root.com/scripts/ian.js but it should be pointing to www.root.com/virtualDir/scripts/ian.js I thought the Base Href tag in the header would help, but so far it does not seem to be helping in anyway. All the links are still pointing to the root website when i hover over them. Any suggestions or ideas are welcome. Thanks

• What is "Virtual Size" in sysinternals process explorer

  - by robert

  Hi My application runs for few hours, There is no increase in any value ( vmsize, memory) of Task Manager. But after few hours i get out of memory errors. In sysinternals i see that "Virtual Size" is contineously increasing, and when it reach around 2 GB i start getting memory errors. So what kind of memory leak is that ? How can i demonstrate it with a code ? Is it possible to reproduce same thing with any piece of code where none of the memory value increase but only the Virtual Size in sysinternsl process explorer increase ? thanks for any suggestions

• SQL server virtual memory usage and performance

  - by user365035

  Hello, I have a very large DB used mostly for analytics. The performance overall is very sluggish. I just noticed that when running the query below, the amount of virtual memory used greatly exceeds the amount of physical memory available. Currently, physical memory is 10GB (10238k bytes) whereas the virtual memory returns significantly more - 8388607k bytes. That seems really wrong, but I'm at a bit of a loss on how to proceed. USE [master]; GO select cpu_count , hyperthread_ratio , physical_memory_in_bytes / 1048576 as 'mem_MB' , virtual_memory_in_bytes / 1048576 as 'virtual_mem_MB' , max_workers_count , os_error_mode , os_priority_class from sys.dm_os_sys_info

• What's the best Street Address Search service?

  - by Gary Russo

  I'm impressed with the simplicity of Microsoft's Virtual Earth Street Address search service. My requirement is to type rough address info with no comma separators into a simple text box, press a find button, wait a few seconds and then observe a result picklist. I mocked up something here using the virtual earth SDK. Does Google Maps have a similar API? Which street address search service is better?

We have many virtual hosts but we've noticed that a potentially malicious user could use his web space to browse other user's files(via a simple php script) and even system files, this could happens due to the php permissions. A way to avoid it is to set the open_basedir var in php.ini, yhis is very simple in a single host system, but in case of virtual hosts there would be a basebir per each host. Ho can I set dis basedir per each user/host? is there a way to let apache hereditate php privileges of the php file that has been requested E.G. /home/X_USER/index.php has as owner X_USER, when apache read the file index.php it checks its path and owner, simply I'm looking for a system set php basedir variable to that path. Thank in advance Lopoc

• Sening a file from memory (rather than disk) over HTTP using libcurl

  - by cinek1lol

  Hi! I would like to send pictures via a program written in C + +. - OK WinExec("C:\\curl\\curl.exe -H Expect: -F \"fileupload=@C:\\curl\\ok.jpg\" -F \"xml=yes\" -# \"http://www.imageshack.us/index.php\" -o data.txt -A \"Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1\" -e \"http://www.imageshack.us\"", NULL); It works, but I would like to send the pictures from pre-loaded carrier to a variable char (you know what I mean? First off, I load the pictures into a variable and then send the variable), cause now I have to specify the path of the picture on a disk. I wanted to write this program in c++ by using the curl library, not through exe. extension. I have also found such a program (which has been modified by me a bit) #include <stdio.h> #include <string.h> #include <iostream> #include <curl/curl.h> #include <curl/types.h> #include <curl/easy.h> int main(int argc, char *argv[]) { CURL *curl; CURLcode res; struct curl_httppost *formpost=NULL; struct curl_httppost *lastptr=NULL; struct curl_slist *headerlist=NULL; static const char buf[] = "Expect:"; curl_global_init(CURL_GLOBAL_ALL); /* Fill in the file upload field */ curl_formadd(&formpost, &lastptr, CURLFORM_COPYNAME, "send", CURLFORM_FILE, "nowy.jpg", CURLFORM_END); curl_formadd(&formpost, &lastptr, CURLFORM_COPYNAME, "nowy.jpg", CURLFORM_COPYCONTENTS, "nowy.jpg", CURLFORM_END); curl_formadd(&formpost, &lastptr, CURLFORM_COPYNAME, "submit", CURLFORM_COPYCONTENTS, "send", CURLFORM_END); curl = curl_easy_init(); headerlist = curl_slist_append(headerlist, buf); if(curl) { curl_easy_setopt(curl, CURLOPT_URL, "http://www.imageshack.us/index.php"); if ( (argc == 2) && (!strcmp(argv[1], "xml=yes")) ) curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headerlist); curl_easy_setopt(curl, CURLOPT_HTTPPOST, formpost); res = curl_easy_perform(curl); curl_easy_cleanup(curl); curl_formfree(formpost); curl_slist_free_all (headerlist); } system("pause"); return 0; }

• C# Exception when retrieving rows from a datagrid in virtual mode

  - by JamesM

  Hi all, I keep getting an exception (see below) when I retrieve a list of rows from a Virtual Mode datagrid, this only happens when I have more rows than I can display on screen and it doesn't happen every time. Is there anything I'm missing with regards to virtual mode? Update The image below shows the problem, the index is now outside the list range. The reason for this is say I have 10 items and I hide 5 as they are not needed and I want to run some code on the 5 that are visible, there are now 5 items but the index of some maybe between 5-9, how can I re-index? When I have run some code on the visible 5 I then show the hidden 5 so I don't want to disgard these, I'd need to reindex again when they are all visible. Many thanks.

• Maven 2.1.0 not passing on system properties to Java virtual machine

  - by raisercostin

  We use the command line to pass on system properties to the Java virtual machine when running our Hudson builds on a Linux box. It used to work quite well in 2.0.9 by since we upgraded to 2.1.0 it has stopped working altogether. The system properties just never make it to the Java virtual machine. I have created a small test project and indeed it does not work at all. I have attached it in case you want to give it a go. This should work just fine with Maven 2.0.9: mvn2.0.9 -Dsystem.test.property=test test But this will fail: mvn2.1 -Dsystem.test.property=test test The Java code simply does this assertTrue( System.getProperty("system.test.property") != null); , Apr 20, 2009; 12:44pm edward eric pedersson

• Portable way to determining of printer is physical or virtual

  - by Mud

  I need direct-to-printer functionality for my website, with the ability to distinguish a physical printer from a virtual printer (file). Coupons.com has this functionality via a native binary which must be installed by the user. I'd prefer to avoid that. SmartSource.com does it via Java applet: Does anybody know how this is done? I dug through that Java APIs a bit, and don't see anything that would let you determine physical vs virtual, except looking at the name (that seems prone to misidentification). It would be nice to be able to do it in Java, because I already know how to write Java applets. Failing that, is there a way to do this in Flash or Silverlight? Thanks in advance. EDIT: Well deserved bounty awarded to Jason Sperske who worked out an elegant solution. Thanks to those of you who shared ideas, as well as those who actually investigated SmartSource.com's solution (like Adrian).

• SQL server virtual memory usage and perofrmance

  - by user365035

  Hello, I have a very large DB used mostly for analytics. The performance overall is very sluggish. I just noticed that when running the query below, the amount of virtual memory used greatly exceed the amount of physical memory available. Currently, phsycial memory is 10GB (10238 bytes) where as the virtual memory returns significantly more 8388607 bytes. That seems really wrong, but I'm at a bit of a loss on how to proceed. USE [master]; GO select cpu_count , hyperthread_ratio , physical_memory_in_bytes / 1048576 as 'mem_MB' , virtual_memory_in_bytes / 1048576 as 'virtual_mem_MB' , max_workers_count , os_error_mode , os_priority_class from sys.dm_os_sys_info

• How to rewrite to a virtual directory with a different application

  - by Eytan Levit

  Hi, I have a CMS application that manages multiple websites, today whenever i change the codebehind of one of these websites - i have to rebuild the dll for all websites, deploy it - this disconnects all current sessions and is really bad. The iis is configured to listen to all domain requests, if the request is to one of the websites' domain , the application rewrites it, or example, if someone requests for http://www.example.com, and example.com is configured in the application to be website 12, it is rewritten to http://www.example.com/websites/12/default.aspx. This is done for all websites. We want to seperate the dlls of the websites from each other, and from the main CMS, we have a virtual directory to each websites, but when trying to rewrite to it, we discover that IIS support this (we get an "Could not load type '_12._Default'". error). How can we perform this rewrite so it does rewrite to virtual directories, or if anyone has any other solution for the initial dll seperation problem. Thanks in advance

• convert from physical path to virtual path

  - by user710502

  I have this function that gets the fileData as a byte array and a file path. The error I am getting is when it tries to set the fileInfo in the code bewlo. It says 'Physical Path given, Virtual Path expected' public override void WriteBinaryStorage(byte[] fileData, string filePath) { try { // Create directory if not exists. System.IO.FileInfo fileInfo = new System.IO.FileInfo(System.Web.HttpContext.Current.Server.MapPath(filePath)); //when it gets to this line the error is caught if (!fileInfo.Directory.Exists) { fileInfo.Directory.Create(); } // Write the binary content. System.IO.File.WriteAllBytes(System.Web.HttpContext.Current.Server.MapPath(filePath), fileData); } catch (Exception) { throw; } } When debugging it, is providing the filePath as "E:\\WEBS\\webapp\\default\\images\\mains\\myimage.jpg" . And the error message is 'E:/WEBS/webapp/default/images/mains/myimage.jpg' is a physical path, but a virtual path was expected. Also, what it is triggering this to happen is the following call properties.ResizeImage(imageName, Configurations.ConfigSettings.MaxImageSize, Server.MapPath(Configurations.EnvironmentConfig.LargeImagePath));

• Using virtual fields in Doctrine_Query

  - by James Maroney

  Is there a way to insert logic based on virtual fields into a Doctrine_Query? I have defined a virtual field in my model, "getStatus()" which I would ultimately like to utilize in a Where clause in my Doctrine_Query. ... ->AndWhere('x.status = ?',$status); "status", however, is not a column in the table it is instead computed by business logic in the model. Filtering the Collection after executing the query works in some situations, but not when a Doctrine_Pager is thrown in the mix, as it computes it's offsets and such before you have access to the Collection. Am I best off ditching Doctrine_Pager and rebuilding that functionality after modifying the Doctrine_Collection?

• Pure virtual destructor in interface

  - by ALOR

  Hello all. Here is my problem. I'm making C++ dll, which extensively relies on instance object exports. So i return my actual instances as a pointers to interface through some exported factory method. Interfaces i use are purely virtual, to avoid linking problame. So i need a pure virtual destructor too, and i implemented one (with empty body, as i googled it). All compiles perfectly well, except... I can't see, if the actual destructors are called or not - because when i added some std::cout << "hello destructor"; i never get to see it. I have some explicit "delete obj", that's not the problem. Am i missing something? Is there another way to delete my object through interface?
