DNSCrypt-Proxy specific usage

- by trekkiejonny

I have some specific usage questions about DNSCrypt-Proxy. I followed a guide and ended with the command dnscrypt-proxy --daemonize –user=dnscrypt Without any further switches does it default to using OpenDNS's resolver server? I want to use specific servers, I found reference to pointing it to the full path of a CSV file. What is the CSV format for use with DNSCrypt? Would it be "address:port,public key"? Does it go in order of working addresses? For example, first resolver doesn't connect it moves on to the second line of the CSV, then third etc. Lastly, would this question be more appropriate in another StackExchange section?

Error creating an .img file from an .ISO (MD5 verified)

- by Rob

I was following the instructions on this website to create a bootable USB flash drive on a Mac: http://www.ubuntu.com/download/help/create-a-usb-stick-on-mac-osx The instruction: hdiutil convert -format UDRW -o ~/path/to/target.img ~/path/to/ubuntu.iso does not create a valid file that the disk utility can copy to the USB drive, making installation on a USB drive useless. I've been repeating these instructions for days with no luck. The only thing that does not work is the .ISO to .IMG conversion. Is there a way to download Ubuntu 12.04 LTS 64-but Desktop in a .IMG file already? Unfortunately, my install notebook does not have an optical drive so USB is the only way. Thanks for your help!

Overview of XSLT

- by kaleidoscope

XSLT (Extensible Stylesheet Language Transformations) is a declarative- XMLbased language used for the transformation of XML documents into other XML documents. Using XSLT , the original document does not changed; rather, a new document is created based on the content of an existing one. XSLT is developed by the World Wide Web Consortium (W3C). Using XSLT we can transform source xml file into another xml file, word file or Excel file. XSLT Functions : - There are the following built - in XSLT functions : Name Description current() Returns the current node document() Used to access the nodes in an external XML document element-available() Tests whether the element specified is supported by the XSLT processor format-number() Converts a number into a string function-available() Tests whether the function specified is supported by the XSLT processor generate-id() Returns a string value that uniquely identifies a specified node key() Returns a node-set using the index specified by an <xsl:key> element system-property() Returns the value of the system properties unparsed-entity-uri() Returns the URI of an unparsed entity For more information – http://www.w3schools.com/xsl/default.asp Technorati Tags: Ritesh, Overview of XSLT

Missing error handling in Streaming-AJAX-Proxy Log

- by Michael Freidgeim

We are using AjaxProxy(FROM http://www.codeproject.com/KB/ajax/ajaxproxy.aspx) on our web site, but started to notice errors accessing log.txt file. I found that the file is created by Log class and doesn't have ability to switch it off and error handling. I've added reading file name from configuration and try/catch block public static class Log { private static StreamWriter logStream; private static object lockObject = new object (); public static void WriteLine(string msg) { string logFileName = ConfigurationExtensions.GetAppSetting("AjaxStreamingProxy.LogFile" ,""); if (logFileName.IsNullOrEmpty()) return; try { if (logStream == null ) { lock (lockObject) { if (logStream == null ) { logStream = File.AppendText(Path .Combine(AppDomain.CurrentDomain.BaseDirectory, logFileName)); } } } logStream.WriteLine(msg); } catch (Exception exc) { string ignoredMsg = String .Format("The error occured while logging {0}, but processing will continue.\n {1} ", exc); LoggerHelper.LogEvent(ignoredMsg, MyCategorySource, TraceEventType .Warning, true); } }

HTTP resource bundling/streaming practice

- by icelava

Our SPA (plain HTML and Javascript) makes use of huge volume of javascript and other resources that are downloaded via XHR. Given the sheer number of components and browser simultaneous request limits, we're thinking for ways to deliver our resources in a more efficient manner. A method we're considering is bundling several resources that logically form a coherent group into a single file; thus reducing down to only one XHR (per group). Furthermore to make it more responsive, we'd like to constantly inspect the partial responseText during the LOADING state, determining if a usable chunk (atomic resource) has already been downloaded, and make it available for deserialization/processing even before the XHR is DONE. (a stream-like experience) We're thinking surely somebody else would've considered roughly the same approach before, but haven't really come across any library/framework or container file format that is suitable for our scenario. Anybody else know of something similar?

What is the best stucture of SEO friendly URL?

- by Aajahid

I'm working for a website to convert the website URL to an SEO friendly URL. I plan to use this: mysite.com/category-name/pageid-123-page-name I looked at some similarly categorized, highly ranked websites. They have the same structure, except for one thing. In one case, the URL format was thissite.com/category-name/pageid-123-page-name.html Another was thatsite.com/category-name/pageid-123-page-name.php Now I know the text in URLs help with SEO. Is it more helpful to have a file extension? If yes, which one is better? Or if my current plan is okay, will it be better with a / at the end?

Would md5 hashes allow detection of synced files?

- by codpursue

We have to develop our own file management system in Java web application. We need to sync files between our main server and client severs and find out whether all the client server has all the latest version of files. Our files are in pdf, doc and xls format they changes every now and then as and when it is required. What we are thinking of using MD5 checksum to find out hashcode of files on Main server and store it in database. Same would be there in Client Servers database. After comparing records on database we would come to know whether client servers are synced or not. Please suggest if there are any better ways to do the same.

How to implement custom texture formats in Android?

- by random1337

What I know: Android can load PNG, BMP, WEBP,... via BitmapFactory. What I want to achive: Load my own 2D file format (e.g. 1-bit texture with a 1-bit alpha channel) and output a RGBA8888 texture. Question: Is there any interface to achieve this?(or any other way) The resulting image is used as a texture for a 3D model. Why would you do that? Saving phone memory and download bandwidth while expanding the texture at runtime to RAM seems reasonable for very simple textures.

I need to access them in Ubuntu to format them and place folders on them but I can not see them or figure out how to access them. Q2. Only 4 of the six drives connected to the MB are showing in Ubuntu, but they show as active in grey hole. I also need to access these drives in Ubuntu as this is my storage server.

How do I convert a partially transparent image into polygons?

- by user82779

I'm using GLEE2D, a level editor allowing me to import images, scale them, rotate them, and position them onto layers and export the data into XML format. However, it does not tell me objects' boundaries. I can calculate them, but only given the original image's polygons. How do I get polygons of objects in a transparent image? An example object (I outlined it): How would I turn the object, knowing the scaled size of the image, into polygons? Is there an algorithm for this? I'll use OpenGL to draw them.

Subdomains vs. URL Path in shareable links

- by Adam Matan

I am building a web application for questions and answers. Each question/answer page has all the required metadata for Facebook and Twitter, and we encourage users to share these pages. I have a dilemma regarding the shared link structure: Option 1 - subdomains Use a questions.example.com and answers.example.com, followed by an ID and optional text. The text is ignored by the request, which only takes the id into account. http://questions.example.com/<question_id>/<question_text> http://questions.example.com/12345/how-long-is-the-queue # Example http://q.example.com/12345 # Example Option 2 - URL path This is the format used by stackoverflow.com and trello.com: http://example.com/questions/<question_id>/<question_text> http://example.com/questions12345/how-long-is-the-queue # Example http://example.com/q/12345 # Example Server-wise, I can easily do both - I have a wildcard SSL certificate and Apache/NGinx configuration is pretty straightforward. Which option - subdomains or URL path - is preferred for shareble links?

Does anyone use 12.04 with HD 6950?

- by Midori

Back when I first tried to switch from Windows to Ubuntu (6-7 months ago) I had several graphics related problems. The VGA was overheating, graphic glitches, video playing issues, slow/choppy window movements etc. After 2-3 reinstalls, hours of playing with different drivers/settings I decided to return to Windows :\ Now I want to give it another shot. But before I start to format, partitioning, backup and other time consuming stuff I wanted to ask if anyone using the 12.04 with HD 6950. Can I utilize the full potential of it, or the drivers are still not good enough? I know that Linux isn't meant to play games in the first place, but the games I playing (SC2, BLC, HoN, DotA 2) are working with wine as far as I know (or aren't?) and I can't find any reason not to switch from Windows if I can utilize the full potential of my config in Ubuntu. So anyone who got experiences with this VGA in Ubuntu please reply. Thanks in advance :)
