• What is the most efficient way to store and access images

  - by MT

  I am working on a project which has to store tens and thousands of images on a server and let the users access them. I need the most efficient method to store these images and to retrieve them. Also, I need information about which technology I should opt. I haven't started the project yet. So, I am thinking between PHP w/ CodeIgniter and Ruby on Rails. PS: The site is something similar to Flickr except that the images are uploaded only by the Authors of the content, and not by the users.

• Deny access to a PHP file (Nginx)

  - by Desmond Hume

  I want Nginx to deny access to a specific PHP file, let's call it donotexposeme.php, but it doesn't seem to work, the PHP script is run as usual. Here is what I have in the config file: location / { root /var/www/public_html; index index.php; } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /var/www/public_html$fastcgi_script_name; include fastcgi_params; } location /donotexposeme.php { deny all; } Of course, I do sudo service nginx reload (or restart) each time I edit the config.

• Access violation C++ (Deleting items in a vector)

  - by Gio Borje

  I'm trying to remove non-matching results from a memory scanner I'm writing in C++ as practice. When the memory is initially scanned, all results are stored into the _results vector. Later, the _results are scanned again and should erase items that no longer match. The error: Unhandled exception at 0x004016f4 in .exe: 0xC0000005: Access violation reading location 0x0090c000. // Receives data DWORD buffer; for (vector<memblock>::iterator it = MemoryScanner::_results.begin(); it != MemoryScanner::_results.end(); ++it) { // Reads data from an area of memory into buffer ReadProcessMemory(MemoryScanner::_hProc, (LPVOID)(*it).address, &buffer, sizeof(buffer), NULL); if (value != buffer) { MemoryScanner::_results.erase(it); // where the program breaks } }

• Restricting IFRAME access in PHP

  - by m0j0

  I am creating a small web page using PHP that will be accessed as an IFRAME from a couple of sites. I'm wanting to restrict access to this site to work ONLY within the "approved" sites, and not other sites or accessed directly. Does anyone have any suggestions? Is this even possible? The PHP site will be Apache, and the sites iframing the content will probably be .NET. Just to clarify, any site can view the page, as long as it's iframe'd within an approved site. I want to block people from accessing it directly. I'm thinking cookies might be a solution, but I'm not sure.

• Ruby on Rails - can't access datetime model object

  - by NomadicRiley

  I've created a model that has 3 string columns and a datetime. Everything is running in SQLite3 and I can view the records in my table just fine using Lita. I'm trying to display the values in a page (index action) using code like this: <% @details.each do |lifeCycle| % <%= debug(lifeCycle)% <%= lifeCycle.lifeCycleId % <%= lifeCycle.eventType % <%= debug(lifeCycle.timeId) % <% end % From the debug I get a result like this: --- !ruby/object:LifeCycle attributes: eventType: Order created_at: "2111359287.23037" timeId: "2455364.89983796" eventId: "98765" updated_at: "2111359287.23037" lifeCycleId: "12345" id: "1" attributes_cache: {} But whenever I try to access the event timeId - i' getting a nil value. This is true if i try to run debug on just that field debug(lifeCycle.timeId), or call a function on it. Is there something obvious I'm missing here?

• Possible to use Javascript to access the client side's network(knowingly)

  - by Earlz

  I recently found an exploit in my router to basically give me root access. The catch? There is a nonce hidden form value that is randomly generated and must be sent in for it to work that makes it difficult to do "easily" So basically I'm wanting to do something like this in javascript: get http://192.168.1.254/blah use a regex or similar to extract the nonce value put the nonce value into a hidden field in the current page submit the form by POST to http://192.168.1.254/blah complete with the nonce value and other form values I want to send in. Is this at all possible using only HTML and Javascript? I'm open to things like "must save HTML file locally and then open", which I'm thinking is one way around the cross domain policy. But anyway, is this at all possible? I'm hoping for this to be able to run from at least Firefox and Chrome. The audience for this is those with some technical know how.

• Linux File Permissions & Access Control Query

  - by Jason

  Hi, Lets say I am user: bob & group: users. There is this file: -rw----r-- 1 root users 4 May 8 22:34 testfile First question, why can't bob read the file as it's readable by others? Is it simply that if you are denied by group, then you are auto-blacklisted for others? I always assumed that the final 3 bits too precedence over user/group permission bits, guess I was wrong... Second question, how is this implemented? I suppose it's linked to the first query, but how does this work in relation to Access Control, is it related to how ACLs work / are queried? Just trying to understand how these 9 permission bits are actually implemented/used in Linux. Thanks alot.

• Java : Using parent class method to access child class variable

  - by Jayant

  I have the following scenario : public class A { private int x = 5; public void print() { System.out.println(x); } } public class B extends A { private int x = 10; /*public void print() { System.out.println(x); }*/ public static void main(String[] args) { B b = new B(); b.print(); } } On executing the code, the output is : 5. How to access the child class(B's) variable(x) via the parent class method? Could this be done without overriding the print() method (i.e. uncommenting it in B)? [This is important because on overriding we will have to rewrite the whole code for the print() method again]

• Access property from include inside a class method in PHP

  - by Jojo

  How do you make a class property available to the other included file inside the same class' method? // file A.php class A { private $var = 1; public function go() { include('another.php'); } } in another file: // this is another.php file // how can I access class A->var? echo $var; // this can't be right Is this possible given the scope. If var is an array then we can use extract but if var is not, we can wrap it in an array. Is there a better way? Thanks!

  For an application we want to achieve zero database and application down time using Active Active configuration. Our dB is Oracle Following are my questions: How can we achieve active active configuration in Oracle? Will introducing Cassandra/HBase(or any other No SQL dbs) cloud help in zero downtime or it is only for fast retrieval of data in a large db? Any other options? Thanks and Regards, Hiral

• Should a webserver in the DMZ be allowed to access MSSQL in the LAN?

  - by Allen

  This should be a very basic question and I tried to research it and couldn't find a solid answer. Say you have a web server in the DMZ and a MSSQL server in the LAN. IMO, and what I've always assumed to be correct, is that the web server in the DMZ should be able to access the MSSQL server in the LAN (maybe you'd have to open a port in the firewall, that'd be ok IMO). Our networking guys are now telling us that we can't have any access to the MSSQL server in the LAN from the DMZ. They say that anything in the DMZ should only be accessible FROM the LAN (and web), and that the DMZ should not have access TO the LAN, just as the web does not have access to the LAN. So my question is, who is right? Should the DMZ have access to/from the LAN? Or, should access to the LAN from the DMZ be strictly forbidden. All this assumes a typical DMZ configuration.

• Installing Oracle Client 11.1.0.7 on Windows Server 2008 64-bit. What does "Install Location" and "S

  - by Anders

  I am trying to install Oracle Client 11.1.0.7 on a Windows Server 2008 64-bit. To some this might not be rocket science but I can't understand what the options under the install screen "Specify Home Details" mean. The defaults given suggest that I use Oracle Base and install software under my own account name. It also suggests that each user should have a separate Oracle Base. This seems counter intuitive to me. I am doing a server install after all. All I want to use the installation for is to connect to an Oracle Database from Reporting Services. Can I safely ignore this and just accept the defaults? What are the implications if I change the location to a common directory?

• How can I determine which switch the Infiniband subnet manager is running on?

  - by ajdecon

  I recently inherited an Infiniband network containing multiple switches, and I know that one of these switches is running the subnet manager. The rest supposedly have that feature turned off, or were never enabled. The trouble is, I have no idea which one it is... I'd like to replace the switch subnet manager with OpenSM running on a couple of my infrastructure servers. Is there any way, short of logging into each switch individually, to determine which switch is running the SM?
