• Uploading a Website

  - by 01010011

  Hi, This is my first time building a website and using CodeIgniter for a school project. I was wondering whether you have any tips on uploading CI to a free web host , my database, free webhosting and basic security tips. Can I just upload the entire CI folder? Or do I have to upload individual files (God no!)? What are my options? What about my MySQL database - do I just upload my mysqldump to the webhost? Also, can you recommend a good free webhost. I was thinking about 000webhost. Any basic tips on security would also be appreciated (I've implemented many of the form_validation rules like xss_clean for starters) Any other suggestions will be more than welcome. Thanks!

• OpToSoapDomComv.TRefCache.FNodes contains references to non-existing XMLNodes

  - by Bascy

  In our D2007 application we are using a Webservice, accessed with a THTTPRIO object. When the TDatamodule containing the THTTPRIO object is Destroyed an access violation occurs. This AV is raised when the TSoapDOMConvert is freed, which in turn executes: TRefCache(RefMap[0].Instance).Free calling destructor TRefCache.Destroy; begin FHREFs.Free; FMHREFs.Free; FNodes := nil; //Causes AV end; FNodes is a TInterfaceList containing one reference to IXMLNodes, but the object seems to have been freed before all this. Does anyone know this problem? How to solve it?

• Storing objects in STL vector - minimal set of methods

  - by osgx

  Hello What is "minimal framework" (necessary methods) of object, which I will store in STL <vector>? For my assumptions: #include <vector> #include <cstring> using namespace std; class Doit { private: char *a; public: Doit(){a=(char*)malloc(10);} ~Doit(){free(a);} }; int main(){ vector<Doit> v(10); } gives *** glibc detected *** ./a.out: double free or corruption (fasttop): 0x0804b008 *** Aborted and in valgrind: malloc/free: 2 allocs, 12 frees, 50 bytes allocated.

• Taking too long to get skills for entry level programmer position [closed]

  - by greenonion

  I don't have the skills for an entry level position as a .Net programmer. I am trying to learn what I need but there is too much to learn and too little time. What can I do? About two months ago, I went to a job interview for an entry level C# .Net programming/consultant position in NYC. When I heard back from them, they told me that the knowledge gap between what I knew and what they needed me to know was too big and I might have been a better fit if I had 6 months of experience. This was the first interview that I went on since graduating college. before the interview, I read a book on visual C#. Turns out it wasn't a very good book and I was missing a lot of key areas of knowledge such as ADO.net SQL (I had learned some LINQ) A little bit about how memory is handled Multiple threaded programming, etc. Because the book wasn't very good, the stuff I did know, I didn't know very well. I felt crushed. I've applied for jobs to gain experience but when recruiters hear that I have no experience they lose interest. I figured that I can at least work on my knowledge. Since then, I read "SQL Essentials" to cover the SQL bit and I found a pretty awesome book that is good enough to clear up what's hazy in my mind and covers almost all of the extra topics. The book is "C# 4.0: The Complete Reference" by Herbert Schildt. I'm even learning a lot about the topics I was familiar with. For a month now I've been working my way through this beast of a book. However, gaining the knowledge I need is taking too long. I can't hold off not having a full-time job much longer. I'm not stupid and I'm studying constantly pouring through the book, asking questions on stackoverflow, referencing the C# specification, etc. I have made great progress but there is just too much ground to cover. I'm on chapter 12 which is about a 3rd through the book. To get an idea of what I know vs don't know, the table of contents is on amazon: http://www.amazon.com/C-4-0-The-Complete-Reference/dp/007174116X How on earth can someone know enough to function as a programmer in the real world? Can I try for a job in academia? Will I have time to finish learning the rest of the C# language or am I just un-hireable?

• Freeing a character pointer returns error

  - by Kraffs

  I'm trying to free a character pointer after having used it but it returns a strange error. The error says: "_CrtDbgREport: String too long or IO Error" The debugger itself returns no errors while compiling. The code currently looks like this: void RespondToUser(SOCKET client, SOCKET server) { char buffer[80]; char *temp = malloc(_scprintf("HTTP/1.1 200 OK\r\n%s\r\nServer: %s\r\nConnection: close\r\n\r\nHi!", buffer, SERVER_NAME)); sprintf(temp, "HTTP/1.1 200 OK\r\n%s\r\nServer: %s\r\nConnection: close\r\n\r\nHi!", buffer, SERVER_NAME); send(client, temp, strlen(temp), 0); closesocket(client); free(temp); ListenToUsers(server); } The problem only occurs when I try to free the temp pointer from the memory and not otherwise. What might be causing this?

• Change kernel used by Ubuntu Server on boot

  - by Tim Fountain

  I have a VPS running Ubuntu server 12.04. A while ago, my host installed an alternative kernel (one of Amazon's EC2 kernels) to fix a boot issue I was having. Now, 2 Ubuntu releases later, this kernel (2.6.31-302-ec2) is still being used even though later (3.2.xx) kernels have been installed. How can I make the server use the most recent installed kernel, preferably without just uninstalling the EC2 kernel just in case doing so causes issues?

• What version(s) of Android should I be targeting?

  - by Bill Osuch

  If you're wondering about what screen sizes and flavors of Android are currently out in the wild, the Android Developers site has a handy little chart of both (each image below is hyperlinked to the page): So, as far as platforms go, there aren't many people still out there running less than 2.X... and you'd probably be safe not worrying about Small or Low Density screens. I'd be curious to know if any of the other app stores (Amazon, Archos, etc.) offer similar stats...

• Cloud just for hosting big files?

  - by yes123

  I need a solution to store my big files (50MB+ each). Currently I am using an european dedicated server (100MBits) with 8000GB/motnh at 60USD. I would like to use a cloud service that autmatically fetches my files from my server the first time users request it (like a classic cdn) (So I can have all files stored within 1 server) I was looking at Amazon CloudFront and, to get the same bandwidth 8'000 GB/month, I have to pay like 2000 USD vs my 60 USD of my dedicated server. Is there a cheaper alternative?

• Should I put a try-finally block after every Object.Create?

  - by max

  I have a general question about best practice in OO Delphi. Currently, I put try-finally blocks anywhere I create an object to free that object after usage (to avoid memory leaks). E.g.: aObject := TObject.Create; try aOBject.AProcedure(); ... finally aObject.Free; end; instead of: aObject := TObject.Create; aObject.AProcedure(); .. aObject.Free; Do you think it is good practice, or too much overhead? And what about the performance?

• Exploring Semantic Search Key Term Relevance

  SQL Server's 'Semantic Search' feature seemed an exciting feature when first shown. Was it really true that Microsoft had come up with a system to rival the industry-leaders, one that could extract the contextual meaning of terms in text, or automatically categorise the subject matter of text? On first inspection, it seems unlikely. Schedule Azure backupsRed Gate’s Cloud Services makes it simple to create and schedule backups of your SQL Azure databases to Azure blob storage or Amazon S3.

• Getting Started With XML Indexes

  XML Indexes make a huge difference to the speed of XML queries, as Seth Delconte explains; and demonstrates by running queries against half a million XML employee records. The execution time of a query is reduced from two seconds to being too quick to measure, purely by creating the right type of secondary index for the query.

• Allocate from buffer in C

  - by Grimless

  I am building a simple particle system and want to use a single array buffer of structs to manage my particles. That said, I can't find a C function that allows me to malloc() and free() from an arbitrary buffer. Here is some pseudocode to show my intent: Particle* particles = (Particle*) malloc( sizeof(Particle) * numParticles ); Particle* firstParticle = <buffer_alloc>( particles ); initialize_particle( firstParticle ); // ... Some more stuff if (firstParticle->life < 0) <buffer_free>( firstParticle ); // @ program's end free(particles); Where <buffer_alloc> and <buffer_free> are functions that allocate and free memory chunks from arbitrary pointers (possibly with additional metadata such as buffer length, etc.). Do such functions exist and/or is there a better way to do this? Thank you!

• How to fork my android app?

  - by eidylon

  So I've written my first Android app, ... and want to be able to provide both free and paid versions. I wrote and compiled it in Eclipse on Windows. I'm wondering if it is possible, and how I would go about doing so, to have separate compile jobs somehow, so that I can maintain my free and paid versions from one set of source code, and just leave out certain bits for the paid version, but keep the main source the same. What are the recommended ways/best practices for devving a paid and free version of the same app from one set of source? Is it even possible?
