• How can I programmatically find the IP address/netmask/gateway configured for a specific network dev

  - by Oren S

  Hi I would like to write a piece of code which checks, for each network device (e.g. eth0, lo, master devices) some statistics and configuration data about that device. I could find the statistics data (and most of the configuration data) in /sys/class/net/..., however, I couldn't find any C/C++ API or any entry in procfs/sysfs listing the inet addr, netmask and gateway. Some alternatives I checked: parsing the output from ifconfig/route/some other utilities: I don't want to start a subprocess every time I need to do the inspection. parsing /etc/sysconfig/network-scripts/: will give me only the start-up configuration, and not the current state. Also, since this code is intended for a product in my workplace, where every external library is inspected thoroughly (meaning it will take me forever to add any external library) I prefer solutions which rely on Linux native API and not external libraries. Thanks!

• Why is this exception thrown when trying to match this regex in Java?

  - by Scott Ferguson

  I'm trying to match a specific string out of a an HTML document and have this regex pattern to grab it: Pattern somePattern = Pattern.compile("var json = ({\"r\":\"^d1\".*});"); However when I try to hit that code at runtime, I get this error: FATAL EXCEPTION: Timer-0 java.util.regex.PatternSyntaxException: Syntax error U_REGEX_RULE_SYNTAX near index 13: var json = ({"r":"^d1".*}); ^ at com.ibm.icu4jni.regex.NativeRegEx.open(Native Method) at java.util.regex.Pattern.compileImpl(Pattern.java:383) at java.util.regex.Pattern.<init>(Pattern.java:341) at java.util.regex.Pattern.compile(Pattern.java:317) Can anybody tell me what I'm doing wrong?

• How do I send a PDF in a MemoryStream to the printer in .Net?

  - by Ryan ONeill

  I have a PDF created in memory using iTextSharp and contained in a MemoryStream. I now need to translate that MemoryStream PDF into something the printer understands. I've used Report Server in the past to render the pages to the printer format but I cant use it for this project. Is there a native .Net way of doing this? For example, GhostScript would be OK if it was a .Net assembly but I don't want to bundle any non .Net stuff along with my installer. The PrintDocument class in .Net is great for sending content to the printer but I still need to translate it from a PDF stream into GDI at the page level. Any good hints? Thanks in advance Ryan

• Disk-based caching of dynamic images in IIS 7

  - by Daniel Schierbeck

  I'm writing an image server which needs to handle a relatively large number of concurrent requests (~5,000). The images being served are dynamically scaled down and cropped based on per-image specifications, which are queried from a database. The number of images is rather large, so an in-memory cache isn't viable (thrashing would most definitely occur). I'm using native caching in IIS 7 to avoid hitting the ASP.NET app which generates the images on-the-fly. I've looked around, but I couldn't find a simple way to configure IIS to store the cache on-disk -- is there such an option, or would I need to roll my own? I'd rather avoid placing the generated images in a public folder, so they can be served statically, since I would prefer to invalidate the cache entries using a query parameter (last-edit time from the database,) which doesn't seem possible to reconcile with static caching. I would love to get some feedback on this!

• Java library to encode / decode AMF

  - by Ceilingfish

  Hi chaps, I currently have a Java server that talks to a Flash client by passing JSON encoded data over a binary socket connection. Is there a way on either side to encode / decode packets as AMF instead of JSON? It seems to me that there should be some native support in Flash player for doing this? All the implementations I have found of AMF serialization seem to be embedded inside an application framework. Simiarly so, does anyone know if it's possible to decode AMF packets independently of a connection implementation in Flash?

• java.io.IOException: Invalid argument

  - by Luixv

  Hi I have a web application running in cluster mode with a load balancer. It consists in two tomcats (T1, and T2) addressing only one DB. T2 is nfs mounted to T1. This is the only dofference between both nodes. I have a java method generating some files. If the request runs on T1 there is no problem but if the request is running on node 2 I get an exception as follows: java.io.IOException: Invalid argument at java.io.FileOutputStream.close0(Native Method) at java.io.FileOutputStream.close(FileOutputStream.java:279) The corresponding code is as follows: for (int i = 0; i < dataFileList.size(); i++) { outputFileName = outputFolder + fileNameList.get(i); FileOutputStream fileOut = new FileOutputStream(outputFileName); fileOut.write(dataFileList.get(i), 0, dataFileList.get(i).length); fileOut.flush(); fileOut.close(); } The exception appears at the fileOut.close() Any hint?

• spl_object_hash for PHP < 5.2 (unique ID for object instances)

  - by Rowan

  I'm trying to get unique IDs for object instances in PHP 5+. The function, spl_object_hash() is available from PHP 5.2 but I'm wondering if there's a workaround for older versions. There are a couple of functions in the comments on php.net but they're not working for me. The first (simplified): function spl_object_hash($object){ if (is_object($object)){ return md5((string)$object); } return null; } does not work with native objects (such as DOMDocument), and the second: function spl_object_hash($object){ if (is_object($object)){ ob_start(); var_dump($object); $dump = ob_get_contents(); ob_end_clean(); if (preg_match('/^object\(([a-z0-9_]+)\)\#(\d)+/i', $dump, $match)) { return md5($match[1] . $match[2]); } } return null; } looks like it could be a major performance buster! Does anybody have anything up their sleeve?

• Reinstall TeamCity when Tomcat becomes corrupt

  - by dodegaard

  I've got a TeamCity 4 installation where tomcat has bit the dust with the following error "The APR Based Apache Tomcat Native library which allows for optimal performance in production environments was not found in java.library path". It appears this started happening once the JDK was installed on the server to allow for a compile. The JDK has been removed and the JRE reinstalled but still no go. My question is should I reinstall TeamCity completely or is there a way to simply reinstall tomcat so I don't hose the configuration? Your help is greatly appreciated.

• Visual Studio CLR project

  - by Vit

  Hi, so I wanted to try my first CLR project in Visual C++. So I created console project, but since every tutorial I found about CLR programming was using C#, or windows forms, I just tried writing standart c++ Hello Word app using iostream (I think code isnt needed in this case) but I though it will give me some compile error, since iostream uses precompiled functions, and CLR app compiles into MSIL. I assumed that CLR programming using C++ means just using C++ syntax, but different functions for I/O and so. So, basicly, what I want to ask is, can any native console C++ app be compiled into MSIL and run by .NET framework?

• HTML5: HTML VS XHTML spec question regarding comments

  - by NoozNooz42

  In the W3C working draft for HTML5 here's a line I find confusing: http://www.w3.org/TR/html5/introduction.html#html-vs-xhtml Comments that contain the string "--" can be represented in the DOM but not in the HTML syntax or in XML. I can interpret this in two different ways: Comments that contain the string "--" can be represented in XML and in the DOM but not in the HTML syntax Comments that contain the string"--" can be represented in the DOM but neither in the HTML syntax nor in XML. I really find the original formulation highly confusing. Which one does it mean and is it even correct english? Who should I contact if I want to point out that I find such a wording highly confusing and that hence there's a high probability that other non-native english speaker would find this kind of formulation highly confusing too?

• Drawbacks with reading and writing a big file to or from disk at once instead of small chunks?

  - by Johann Gerell

  I work mainly on Windows and Windows CE based systems, where CreateFile, ReadFile and WriteFile are the work horses, no matter if I'm in native Win32 land or in managed .Net land. I have so far never had any obvious problem writing or reading big files in one chunk, as opposed to looping until several smaller chunks are processed. I usually delegate the IO work to a background thread that notifies me when it's done. But looking at file IO tutorials or "textbook examples", I often find the "loop with small chunks" used without any explanation of why it's used instead of the more obvious (I dare to say!) "do it all at once". Are there any drawbacks to the way I do that I haven't understood?

• Skinning WinAPI Controls

  - by Brad

  If you've ever seen an application in the Adobe Creative Suite 5 (CS5), you may have noticed that it doesn't look like the native Windows GUI.. They have modified it to have a different look to it. Where would someone begin to make an application that has a custom skin? CS5 uses the Adobe Source library for it's widget/control management, so I tried downloading and compiling the Adobe Source Library to see if I could make a nice skinned app like Photoshop CS5, but after finally getting it to compile and tested it, I realized the library was only for managing widgets and not skinning the GUI, like CS5 has. Where would I begin to make a nice skinned program like Adobe Cs5 applications? Can anyone point me in the right direction? Do I simply use the WM_PAINT Message from WinAPI and render my own widgets using openGL or something?

• Applying style sheets in pyqt

  Hello all, If i apply a property to a parent widget it is automatically applied for child widgets too.. Is there any way of preventing this?? For example if i set background color as white in a dialog the button,combo boxes and scroll bars looks white as it lacks it native look(have to say it's unpleasant & ugly).. Is there any way that i can apply the stylesheets only to a parent widget not to it's children??? Experts help please..

• Fast 4x4 matrix multiplication in Java with NIO float buffers

  - by kayahr

  I know there are LOT of questions like that but I can't find one specific to my situation. I have 4x4 matrices implemented as NIO float buffers (These matrices are used for OpenGL). Now I want to implement a multiply method which multiplies Matrix A with Matrix B and stores the result in Matrix C. So the code may look like this: class Matrix4f { private FloatBuffer buffer = FloatBuffer.allocate(16); public Matrix4f multiply(Matrix4f matrix2, Matrix4f result) { {{{result = this * matrix2}}} <-- I need this code return result; } } What is the fastest possible code to do this multiplication? Some OpenGL implementations (Like the OpenGL ES stuff in Android) provide native code for this but others doesn't. So I want to provide a generic multiplication method for these implementations.

• Difference between C++ Keyboard keycode and JAVA KeyEvent keycode

  - by Auxiliary

  I noticed a difference between the keycodes that vkCode in C++ gives and the ones that Java's KeyEvent gives us. (Ofcourse the normal characters have the same code (0 = 48 just like the ASCII) but they differ in the other keys). Is there a way to 'translate' them from one to the other (What's the logic behind each one?) or am I supposed to use loads of switches and IFs for that. If it helps, my app is half in C++ and half in JAVA because of the Native Hooks that c++ gives us and it gets the keycodes of the keys that the user presses and then the java is going to use them. Thanks in advance.

• Best compiled language for Mac OS X and Linux compatibility

  - by corydoras

  We need to write some software that will compile and run on both an Mac OS X server and Ubuntu. We would love to use Objective-C with all of its Cocoa goodness, however the GNUstep implementations of the parts we are using are broken (in the latest Ubuntu package anyway.) In light of this should we use C++ (I would really rather not), C or something else that we have not thought of? It is a server/back-end process that is very resource intensive, Java and other interpreted versions of this software perform much worse than the Objective-C proof of concept we have written, hence we now wish to re-write in a "compiled[1]" language. (NB: Some people might consider this subjective, however at the end of the day we do need to get a job done, there has to be a reasonably appropriate correct answer here). [1] Compiled to native CPU instructions, not compiled into "byte codes" that then have to be run by an interpreter.

• Drag-and-drop file upload in Chromium?

  - by Zarel

  Drag-and-drop file uploading can be done in Firefox 3.6 by using FileReader: http://stackoverflow.com/questions/2121018/native-drag-drop-file-upload-in-firefox-3-6 However, Google recently released an update for Gmail that allowed drag-and-drop file uploading in Chromium as well as Firefox, and Chromium does not have FileReader. I'm using the latest Chromium nightly, and it can drag-drop upload files, while not supporting FileReader. I've seen someone mention that drag-drop uploading can be possible by dragging onto an <input type="file" />, but that can only support one file at a time, while Gmail's uploader can handle multiple files being dragged onto it, so that's clearly not what they're doing. So the question is, how do they do it? How do you support Chromium for HTML5 file uploading?

• How can I show SQL Server LOGS (2005)

  - by Marcin Rybacki

  Hello, I'm trying to track the error thrown by SQL Server 2005. The problem is SQL Server reports it in my native language so it's hard for me to google it. I think that the core issue would be avialable in English in SQL Server LOGS. I'm running SQL Server Management Studio Express, going to "Management" node, and then SQL Server Logs. I can see the list of logs but I cannot enter them, the only available option in context menu is Refresh. Could you help me to show the contents of those logs?

• Converting String^ and Collection of String^ to const char*

  - by Jim Jones

  Using VS2008 Managed C++ to wrap a dll. The native method takes a series of single const char* values and a collection of char* values. Going to make an example function: Function1(char * value1, TF_StringList& catList); TF_StringList is a dll class with 3 insert methods, the one I want to use is: TF_StringList::insert(const char* str); So I set up a wrapper method of: WrapperClass::callFunction(String^ mvalue1, ArrayList mcatList); mvalue1 is converted to const char* using: const char* value1 = (char*)(Marshal::StringToHGlobalAnsi(mvalue1)).ToPointer(); However, when a get to the collection of strings, I iterate over it getting each string using the index: String^ mstr = mcatList[i]; Have tried every way of converting String^ to const char* and in every case the TF_StringList::insert(const char* str) method throws a C2663 error which has to do with the const-ness of the value. What is the problem?
