• set iPhone Required device capabilities

  - by chozinul

  My application is for "iPhone ONLY", But I have made a mistake in the first place by not setting the application for specific device. The current setting now is: Requirement: Compatible for iPhone, iPod touch and iPad. I would like to set it to: Requirement: Compatible for iPhone. I have go to some tutorial and forum. and nothing can solve my problem. I have also contact the apple support and this is what I got: "You are permitted to expand your device requirements only. Submitting an update to your binary to restrict your device requirements is not permitted. " is it mean that I can not set my application for iPhone only? If i can change it, what would you recommend me to do? I have change the setting of device capability inside the plist, to one of this. which one is correct, use "UIRequiredDeviceCapabilities" or "Required device capabilities"? i provide the screenshoot in here: http://img218.imageshack.us/gal.php?g=screenshot20100604atam1.png does the way I use it correct? Thanks.

• Open source Java CMS for Google App Engine?

  - by markvgti

  I am looking for an open source Java CMS (Web CMS, actually) to run on Google App Engine. I have looked at related older questions on this topic (What CMS runs on Google AppEngine?, CMS over Google App Engine, with SEO etc.) but the problem is that they all largely list Python-based CMSes. Plus these questions are pretty old, and since GAE is a fast-moving target, I thought it might be worthwhile to ask again. I want a CMS for creating some websites (for myself and for others), but would rather not start writing one from scratch. A "good" (very subjective, I know) open source WCMS allows me to start using a product, while still being able to add to/extend the product/project. On the one hand I am looking for a somewhat mature product/project, on the other hand it's easier to start contributing to the development cycle of a young product/project (conflicting, I know :-). Here are some features that would be preferable: [X]HTML/XML/CSS based templating Ability to create multiple blogs Galleries Ability to create a "Downloads" section (is this pretty much standard?) Separate management for digital assets (images, PDFs, binary files etc.) Roles like "Administrator", "Editor", "Contributor" etc. (or their equivalents) Ability to move/reorganize pages Export to PDF Reformat content for printing Is the CMS you are about to suggest especially well-suited to publishing an online book? My idea is that while the book may be offered as a downloadable eBook, the latest, most current version will be the one available on the website.

• RapidXML, reading and saving values

  - by Layne

  Hello, I've worked myself through the rapidXML sources and managed to read some values. Now I want to change them and save them to my XML file: Parsing file and set a pointer void SettingsHandler::getConfigFile() { pcSourceConfig = parsing->readFileInChar(CONF); cfg.parse<0>(pcSourceConfig); } Reading values from XML void SettingsHandler::getDefinitions() { SettingsHandler::getConfigFile(); stGeneral = cfg.first_node("settings")->value(); /* stGeneral = 60 */ } Changing values and saving to file void SettingsHandler::setDefinitions() { SettingsHandler::getConfigFile(); stGeneral = "10"; cfg.first_node("settings")->value(stGeneral.c_str()); std::stringstream sStream; sStream << *cfg.first_node(); std::ofstream ofFileToWrite; ofFileToWrite.open(CONF, std::ios::trunc); ofFileToWrite << "<?xml version=\"1.0\"?>\n" << sStream.str() << '\0'; ofFileToWrite.close(); } Reading file into buffer char* Parser::readFileInChar(const char* p_pccFile) { char* cpBuffer; size_t sSize; std::ifstream ifFileToRead; ifFileToRead.open(p_pccFile, std::ios::binary); sSize = Parser::getFileLength(&ifFileToRead); cpBuffer = new char[sSize]; ifFileToRead.read( cpBuffer, sSize); ifFileToRead.close(); return cpBuffer; } However, it's not possible to save the new value. My code is just saving the original file with a value of "60" where it should be "10". Rgds Layne

• gcc: Do I need -D_REENTRANT with pthreads?

  - by stefanB

  On Linux (kernel 2.6.5) our build system calls gcc with -D_REENTRANT. Is this still required when using pthreads? How is it related to gcc -pthread option? I understand that I should use -pthread with pthreads, do I still need -D_REENTRANT? On a side note, is there any difference that you know off between the usage of REENTRANT between gcc 3.3.3 and gcc 4.x.x ? When I use -pthread gcc option I can see that _REENTRANT gets defined. Will omitting -D_REENTRANT from command line make any difference, for example could some objects be compiled without multithreaded support and then linked into binary that uses pthreads and will cause problems? I assume it should be ok just to use: g++ -pthread > echo | g++ -E -dM -c - > singlethreaded > echo | g++ -pthread -E -dM -c - > multithreaded > diff singlethreaded multithreaded 39a40 > #define _REENTRANT 1 We're compiling multiple static libraries and applications that link with the static libraries, both libraries and application use pthreads. I believe it was required at some stage in the past but want to know if it is still required. Googling hasn't returned any recent information mentioning -D_REENTRANT with pthreads. Could you point me to links or references discussing the use in recent version of kernel/gcc/pthread? Clarification: At the moment we're using -D_REENTRANT and -lpthread, I assume I can replace them with just g++ -pthread, looking at man gcc it sets the flags for both preprocessor and linker. Any thoughts?

• Bit reversal of an integer, ignoring integer size and endianness

  - by ??O?????

  Given an integer typedef: typedef unsigned int TYPE; or typedef unsigned long TYPE; I have the following code to reverse the bits of an integer: TYPE max_bit= (TYPE)-1; void reverse_int_setup() { TYPE bits= (TYPE)max_bit; while (bits <<= 1) max_bit= bits; } TYPE reverse_int(TYPE arg) { TYPE bit_setter= 1, bit_tester= max_bit, result= 0; for (result= 0; bit_tester; bit_tester>>= 1, bit_setter<<= 1) if (arg & bit_tester) result|= bit_setter; return result; } One just needs first to run reverse_int_setup(), which stores an integer with the highest bit turned on, then any call to reverse_int(arg) returns arg with its bits reversed (to be used as a key to a binary tree, taken from an increasing counter, but that's more or less irrelevant). Is there a platform-agnostic way to have in compile-time the correct value for max_int after the call to reverse_int_setup(); Otherwise, is there an algorithm you consider better/leaner than the one I have for reverse_int()? Thanks.

• Command /Developer/usr/bin/dsymutil failed with exit code 10

  - by Evan Robinson

  I am getting the above error message randomly (so far as I can tell) on iPhone projects. Occasionally it will go away upon either: Clean Restart XCode Reboot Reinstall XCode But sometimes it won't. When it won't the only solution I have found is to take all the source material, import it into a new project, and then redo all the connections in IB. Then I'm good until it strikes again. Anybody have any suggestions? [update 20091030] I have tried building both debug and release versions, both full and lite versions. I've also tried switching the debug symbols from DWARF with external dSYM file to DWARF and to stabs. Clean builds in all formats make no differences. Permission repairs change nothing. Setting up a new user has no effect. Same error on the builds. Thanks for the suggestions! [Update 20091031] Here's an easier and (apparently) reliable workaround. It hinges upon the discovery that the problem is linked to a target not a project In the same project file, create a new target Option-Drag (copy) all the files from the BAD target 'Copy Bundle Resources' folder to the NEW target 'Copy Bundle Resources' folder Repeat (2) with 'Compile Sources' and 'Link Binary With Libraries' Duplicate the Info.plist file for the BAD target and name it correctly for the NEW target. Build the NEW target! [Update 20100222] Apparently an IDE bug, now apparently fixed, although Apple does not allow direct access to the original bug of a duplicate. I can no longer reproduce this behaviour, so hopefully it is dead, dead, dead.

• java Processbuilder - exec a file which is not in path on OS X

  - by Jakob

  Okay i'm trying to make ChucK available in exported Processing sketches, i.e. if i export an app from Processing, the ChucK VM binary will be executed from inside the app. So as a user of said app you don't need to worry about ChucK being in your path at all. Right now i'm generating and executing a bash script file, but this way i don't get any console output from ChucK back into Processing: #!/bin/bash cd "[to where the Chuck executable is located]" ./chuck --kill killall chuck # just to make sure ./chuck chuckScript1.ck cuckScriptn.ck then Process p = Runtime.getRuntime().exec("chmod 777 "+scriptPath); p = Runtime.getRuntime().exec(scriptPath); This works but i want to run ChucK directly from Processing instead, but can't get it to execute: String chuckPath = "[folder in which the chuck executable is located]" ProcessBuilder builder = new ProcessBuilder (chuckPath+"/chuck", "test.ck"); final Process process = builder.start(); InputStream is = process.getInputStream(); InputStreamReader isr = new InputStreamReader(is); BufferedReader br = new BufferedReader(isr); String line; while((line = br.readLine()) != null) println(line); println("done chuckin'! exitValue: " + process.exitValue()); Sorry if this is newbie style :D

• What was Tim Sweeney thinking? (How does this C++ parser work?)

  - by Frank Krueger

  Tim Sweeney of Epic MegaGames is the lead developer for Unreal and a programming language geek. Many years ago posted the following screen shot to VoodooExtreme: As a C++ programmer and Sweeney fan, I was captivated by this. It shows generic C++ code that implements some kind of scripting language where that language itself seems to be generic in the sense that it can define its own grammar. Mr. Sweeney never explained himself. :-) It's rare to see this level of template programming, but you do see it from time to time when people want to push the compiler to generate great code or because they want to create generic code (for example, Modern C++ Design). Tim seems to be using it to create a grammar in Parser.cpp - you can see what look like prioritized binary operators. If that is the case, then why does Test.ae look like it's also defining a grammar? Obviously this is a puzzle that needs to be solved. Victory goes to the answer with a working version of this code, or the most plausible explanation, or to Tim Sweeney himself if he posts an answer. :-)

• Encrypting with Perl CBC and decrypting with PHP mcrypt

  - by Ed

  I have an encrypted string that was encrypted with Perl Crypt::CBC (Rijndael,cbc). The original plaintext was encrypted with encrypt_hex() method of Crypt::CBC. $encrypted_string = '52616e646f6d49567b2c89810ceddbe8d182c23ba5f6562a418e318b803a370ea25a6a8cbfe82bc6362f790821dce8441a790a7d25d3d9ea29f86e6685d0796d'; I have the 32 character key that was used. mcrypt is successfully compiled into PHP, but I'm having a very hard time trying to decrypt the string in PHP. I keep getting gibberish back. If I unpack('H*', $encrypted_string), I see 'RandomIV' followed by what looks like binary. I can't seem to correctly extract the IV and separate the actual encrypted message. I know I'm not providing my information, but I'm not sure where else to start. $cipher = 'rijndael-256'; $cipher_mode = 'cbc'; $td = mcrypt_module_open($cipher, '', $cipher_mode, ''); $key = '32 characters'; // Does this need to converted to something else before being passed? $iv = ?? // Not sure how to extract this from $encrypted_string. $token = ?? // Should be a sub-string of $encrypted_string, correct? mcrypt_generic_init($td, $key, $iv); $clear = rtrim(mdecrypt_generic($td, $token), ''); mcrypt_generic_deinit($td); mcrypt_module_close($td); echo $clear; Any help, pointers in the right direction, would be greatly appreciated. Let me know if I need to provide more information.

• Setting up multiple channel types (AMF/AMFX) for Flex/BlazeDs

  - by Fergal

  We've configured our Flex client to have two channels for calling our services via BlazeDS. One channel is configured to use AMFChannel and the other for HTTPChannel. Here's the services-config.xml <channel-definition id="my-amf" class="mx.messaging.channels.AMFChannel"> <endpoint url="http://{server.name}:{server.port}/{context.root}/data/messagebroker/amf" class="flex.messaging.endpoints.AMFEndpoint" /> <properties> <polling-enabled>false</polling-enabled> </properties> </channel-definition> <channel-definition id="my-amfx" class="mx.messaging.channels.HTTPChannel"> <endpoint url="http://{server.name}:{server.port}/{context.root}/data/messagebroker/amfx" class="flex.messaging.endpoints.HTTPEndpoint" /> <properties> <polling-enabled>false</polling-enabled> </properties> </channel-definition> Our flex client is written to use either AMF or AMFX depending on how we configure it. The problem is that although the client can switch between channels it sends an AMF binary payload when attempting to call services via AMFX (expecting XML). The funny thing is that we can write services-config.xml to use either AMF or AMFX individually but Flex doesn't seem to want to let us use both. Is this a bug in Flex? If not how can we get it to use the correct protocol?

• json_encode with mysql content and umlauts in utf-8

  - by i3rutus

  Hey, i feel my beard growing while trying to find out the Problem here. Basic the Problem is, that Umlauts/Special Signs äöß ... don't work. I guess everyone is sick and tired of that questions but all the solutions found online don't seem to work. Im having utf-8 content in a utf-8 Mysql Database. I feel the Problem ist somewhere in the Database connection but i just can't figure out. character_set_client utf8 character_set_connection utf8 character_set_database utf8 character_set_filesystem binary character_set_results utf8 character_set_server latin1 character_set_system utf8 Im not sure if the problem is the latin1 for character_set_server because im not into that mysql stuff. I also dont know how to change cause i can't access the mysql server's config files. Whatever is confusing me, that if i get my results from the Database and echo it, print_r gives the right result. ini_set('default_charset','utf-8'); header('Content-Type: text/plain; > charset=utf-8'); Firefox says char encode is utf-8 but if when i output: print_r($listnew); echo json_encode($listnew[5]); print_r results everything right but json_encode does wrong. print_r: [5] => Array ( [id] => 5 [data] => U-Bahnhof Theresienstraße [size] => 17 ) json_encode: {"id":5,"data":"U-Bahnhof Theresienstra\u00dfe","size":17} i know json_encode needs a utf-8 string to work properly there and i feel im having a encode trouble here but i just can't firgure out where it is. Any help would be appreciated, thanks in advance. i3

• Fail to load NPAPI plugin in Google Chrome on Mac OS X

  - by Roman

  I have been trying to get Google Chrome (6.0.401.1 dev) on Mac OS X to load an NPAPI plugin without success so far. I have been working around the npsimple example from here: http://git.webvm.net/?p=npsimple. Using gcc on Mac and VC++ 2008 on Windows I managed to get it running on Safari and Firefox on Mac OS X and Firefox and Google Chrome on Windows, but not on Google Chrome on Mac OS X. When trying to debug Google Chrome on Mac OS X it seemed Google Chrome was briefly dyld-loading (and immediately dyld-unloading) the plugin on startup, but without actually looking-up any symbols within the plugin or calling any of the functions. It seemed to be doing that for every plugin, though. Also, when loading a page with the embed-tag for the plugin, Google Chrome did not seem to even dyld-load the plugin and no functions were called (not even NP_GetEntryPoints). Google Chrome also does not output any error message, it just simply does not load the plugin. I am not sure I caught everything with gdb because of Google Chrome using different processes, but I have also tried all the switches like --no-sandbox, --single-process and --plugin-startup-dialog (which incidentally does not seem to work at all on Mac OS X). I also made sure the architecture of the binary matches (i.e. 32-bit for Google Chrome). Has anybody had similar problems before? Is there anything I am missing here, like a gcc switch when compiling or something? Any help would be greatly appreciated.

• Eclipse RAP - Firefox doesn't forget session

  - by Fritz H

  We've got an Eclipse RAP application that's behaving a bit strangely in Firefox - two distinct problems. When you browse around, you can click on a button in one part of the system. This opens a popup window like so: IWorkbenchBrowserSupport bs; bs = PlatformUI.getWorkbench().getBrowserSupport(); int style = IWorkbenchBrowserSupport.AS_EXTERNAL; IWebBrowser b = bs.createBrowser(style, getRandomID(), "Hello world", ""); b.openURL(new URL(...)); where the URL is another servlet in the application. This servlet is in the same runtime, but has nothing to do with RAP - it takes a binary blob from in-memory storage and dumps it in the output stream. Problem 1: This causes the HTTP session to die in firefox, and shows the "session expired" RAP error page with a link to restart the session. Problem 2: Now, when you click on the link to restart the session, it shows the application's dialog again, but the session expired error is shown again the moment you do anything. This prevents the user from using the system again, unless Firefox is closed down completely and restarted. A quick peek with FireBug reveals that the JSESSIONID passed by Firefox does not change. Has anyone seen this before?

• Debugger Visualizer, ElementHost, and Edit and Continue problems

  - by Frank Fella

  I recently wrote a custom Debugger Visualizer for Visual Studio 2008 for one of the custom types in my application. The UI for the visualizer is written in WPF and is hosted in an element host and shown using the IDialogVisualizerService windowService object. Everything works great, and my visualizer loads and shows the relevant information, but if try to "edit and continue" in my application after loading the visualizer, Visual Studio crashes with no useful error message. In trying to debug this I removed almost all of my code from the solution to the point where I was only serializing a string with the ObjectSource and displaying just an empty element host and I still get the crash on edit and continue. If I remove the element host and show a WinForms control or form there is no crash. Here is the Visualizer code: using System; using System.Drawing; using System.IO; using System.Runtime.Serialization.Formatters.Binary; using System.Windows.Forms; using System.Windows.Forms.Integration; using Microsoft.VisualStudio.DebuggerVisualizers; using ObjectVisualizerShared; using ObjectVisualizerUI; namespace ObjectVisualizer { public class Visualizer : DialogDebuggerVisualizer { protected override void Show(IDialogVisualizerService windowService, IVisualizerObjectProvider objectProvider) { try { Stream stream = objectProvider.GetData(); if (stream.Length > 0) { BinaryFormatter formatter = new BinaryFormatter(); VisualizerNode node = (VisualizerNode)formatter.Deserialize(stream); if (node != null) { VisualizerWindow window = new VisualizerWindow(node); ElementHost host = new ElementHost(); host.Child = window; host.Dock = DockStyle.Fill; host.Size = new Size(800, 600); windowService.ShowDialog(host); } } } catch (Exception ex) { MessageBox.Show(string.Format("Error!\n{0}", ex), "Object Visualizer"); } } } } Any ideas?

• using ghostscript in server mode to convert pdfs to pngs

  - by emh

  while i am able to convert a specific page of a PDF to a PNG like so: gs -dSAFER -dBATCH -dNOPAUSE -sDEVICE=png16m -dGraphicsAlphaBits=4 -sOutputFile=gymnastics-20.png -dFirstPage=20 -dLastPage=20 gymnastics.pdf i am wondering if i can somehow use ghostscript's JOBSERVER mode to process several conversions without having to incur the cost of starting up ghostscript each time. from: http://pages.cs.wisc.edu/~ghost/doc/svn/Use.htm -dJOBSERVER Define \004 (^D) to start a new encapsulated job used for compatibility with Adobe PS Interpreters that ordinarily run under a job server. The -dNOOUTERSAVE switch is ignored if -dJOBSERVER is specified since job servers always execute the input PostScript under a save level, although the exitserver operator can be used to escape from the encapsulated job and execute as if the -dNOOUTERSAVE was specified. This also requires that the input be from stdin, otherwise an error will result (Error: /invalidrestore in --restore--). Example usage is: gs ... -dJOBSERVER - < inputfile.ps -or- cat inputfile.ps | gs ... -dJOBSERVER - Note: The ^D does not result in an end-of-file action on stdin as it may on some PostScript printers that rely on TBCP (Tagged Binary Communication Protocol) to cause an out-of-band ^D to signal EOF in a stream input data. This means that direct file actions on stdin such as flushfile and closefile will affect processing of data beyond the ^D in the stream. the idea is to run ghostscript in-process. the script would receive a request for a particular page of a pdf and would use ghostscript to generate the specified image. i'd rather not start up a new ghostscript process every time.

• Why does division yield a vastly different result than multiplication by a fraction in floating points.

  - by Avram

  I understand why floating point numbers can't be compared, and know about the mantissa and exponent binary representation, but I'm no expert and today I came across something I don't get: Namely lets say you have something like: float denominator, numerator, resultone, resulttwo; resultone = numerator / denominator; float buff = 1 / denominator; resulttwo = numerator * buff; To my knowledge different flops can yield different results and this is not unusual. But in some edge cases these two results seem to be vastly different. To be more specific in my GLSL code calculating the Beckmann facet slope distribution for the Cook-Torrance lighitng model: float a = 1 / (facetSlopeRMS * facetSlopeRMS * pow(clampedCosHalfNormal, 4)); float b = clampedCosHalfNormal * clampedCosHalfNormal - 1.0; float c = facetSlopeRMS * facetSlopeRMS * clampedCosHalfNormal * clampedCosHalfNormal; facetSlopeDistribution = a * exp(b/c); yields very very different results to float a = (facetSlopeRMS * facetSlopeRMS * pow(clampedCosHalfNormal, 4)); facetDlopeDistribution = exp(b/c) / a; Why does it? The second form of the expression is problematic. If I say try to add the second form of the expression to a color I get blacks, even though the expression should always evaluate to a positive number. Am I getting an infinity? A NaN? if so why?

• Objective C / iPhone comparing 2 CLLocations /GPS coordinates

  - by user289503

  have an app that finds your GPS location successfully, but I need to be able to compare that GPS with a list of GPS locations, if both are the same , then you get a bonus. I thought I had it working, but it seems not. I have 'newLocation' as the location where you are, I think the problem is that I need to be able to seperate the long and lat data of newLocation. So far ive tried this: Code: NSString *latitudeVar = [[NSString alloc] initWithFormat:@"%g°", newLocation.coordinate.latitude]; NSString *longitudeVar = [[NSString alloc] initWithFormat:@"%g°", newLocation.coordinate.longitude]; An example of the list of GPS locations: Code: location:(CLLocation*)newLocation; CLLocationCoordinate2D bonusOne; bonusOne.latitude = 37.331689; bonusOne.longitude = -122.030731; and then Code: if (latitudeVar == bonusOne.latitude && longitudeVar == bonusOne.longitude) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"infinite loop firday" message:@"infloop" delegate:nil cancelButtonTitle:@"Stinky" otherButtonTitles:nil ]; [alert show]; [alert release]; this comes up with an error 'invalid operands to binary == have strut NSstring and CLlocationDegrees' Any thoughts?

• Packaging a qt application compiled with shared libraries

  - by Surjya Narayana Padhi

  Hi Geeks, I downloaded the qt embedded demo source code recently on my linux machine. Following are the outcomes during running of the program I compiled it statically on my x86 machine and run the application on x86 machine it runs fine. But when i took the statically compiled binary file to other machine with Atom platform It run with some missing widgets. I found that the plugins cant be ported with static compilation. Can anybody tell me is it true? If no can anybody tell me the steps for it? I compiled it dynamically with shared libraries. Then got an executalbe on linux. I did "ldd MyAppName". It show me the shared library files it is using. But I dont know how to package these. Can anybody tell me the steps to package it? I checked in the article on deploying qt applications on X11-linux platforms. But its not complete. Can anybody give me the detailed steps? Any help will be appreciated......

• ThreadAbortException (WebClient using DownloadFile to grab file from server)

  - by baron

  Hi Everyone, Referencing my Earlier Question, regarding downloading a file from a server and handling exceptions properly. I am positive that I had this solved, then in classic programming fashion, returned days later to frustratingly find it broken :-( Updated code: private static void GoGetIt(HttpContext context) { var directoryInfoOfWhereTheDirectoryFullOfFilesShouldBe = new FileInfo(......); var name = SomeBasicLogicToDecideName(); //if (!directoryInfoOfWhereTheDirectoryFullOfFilesShouldBe.RefreshExists()) //{ // throw new Exception(string.Format("Could not find {0}.", name)); //} var tempDirectory = ""; //Omitted - creates temporary directory try { directoryInfoOfWhereTheDirectoryFullOfFilesShouldBe.CopyAll(tempDirectory); var response = context.Response; response.ContentType = "binary/octet-stream"; response.AddHeader("Content-Disposition", string.Format("attachment;filename={0}.zip", name)); ZipHelper.ZipDirectoryToStream(tempDirectory, response.OutputStream); response.End(); } catch (Exception ex) { Debug.WriteLine(ex.ToString()); context.Response.StatusCode = 404; } finally { tempDirectory.DeleteWithPrejudice(); } } This was working fine, and returning the zip, otherwise if the file didn't exist returning 404. Then on the client side I could handle this: public bool Download() { try { using (var client = new WebClient()) { client.DownloadFile(name, tempFilePath); } } catch (Exception) { fileExists = false; } return fileExists; } But the problem now is two things. 1) I get System.Threading.ThreadAbortException: Thread was being aborted in the server side try-catch block. Usually this was just a file not found exception. I have no idea what or why that new exception is throwing? 2) Now that a different exception is throwing on the server side instead of the file not found, it would seem I can't use this set up for the application, because back on client side, any exception is assumed to be filenotfound. Any help, especially info on why this ThreadAbortException is throwing!?!? greatly appreciated. Cheers

• I'm trying to run some PHP scripts as CLI instead of over HTTP. How do I make them play nice?

  - by gnfti

  Hi everyone. I'm using some PHP scripts from FeedForAll to join together RSS feeds (RSSmesh) and display them as HTML (RSS2HTML). Because I intend to run these scripts fairly intensively and don't want the resulting HTTP requests and bandwidth to count towards my hosting quota, I am in the process of moving to running them on the web host's server in an umbrella PHP "batch" script, and call this script via cron (this is a Linux server, by the way). Here's a (working) sample request over HTTP: http://www.mydomain.com/a/rss2htmlcore/rss2html2.php?XMLFILE=http://www.mydomain.com/a/myapp/xmlcache/feed.xml&TEMPLATE=template.html This will produce the desired HTML output. An example of how I want this to work on the command line: /srv/customers/mycustomer#/mydomain.com/www/a/rss2htmlcore/rss2html2-cli.php /srv/customers/mycustomer#/mydomain.com/www/a/myapp/xmlcache/feed.xml /srv/customers/mycustomer#/mydomain.com/www/a/template.html This is with the correct shebang line added to "rss2html2-cli.php". I could just as well specify the executable ("/usr/local/bin/php") in the request, I doubt it makes a difference because I am able to run another script (that I wrote myself) either way without problems. Now, RSS2HTML and RSSmesh are different in that, for starters, they include secondary files -- for example, both include an XML parser script -- and I suspect that this is where I am getting a bit in over my head. Right now I'm calling exec() from the "umbrella" batch script, like so: exec("/srv/customers/mycustomer#/mydomain.com/www/a/rss2htmlcore/rss2html2-cli.php /srv/customers/mycustomer#/mydomain.com/www/a/myapp/xmlcache/feed.xml /srv/customers/mycustomer#/mydomain.com/www/a/template.html", $output) But no output is being produced. What's the best way to go about this and what "gotchas" should I keep in mind? Is exec() the right way to approach this? It works fine for the other (simple) script but that writes its own output. For this I want to get the output and write it to a file from within the umbrella script if possible. I've also tried output buffering but to no avail. Do I need to pay attention to anything specific with regard to the includes? Right now they're specified in the scripts as include_once("FeedForAll_XMLParser.inc.php"); and the specified files are indeed in the same folder. Further info: -This is a Linux server. -I have no direct access to the shell, so I can't test things directly on a command line, everything is via crontab. -I will admit that support for the FeedForAll scripts leaves a lot to be desired, but I'd like to keep using their scripts if at all possible, if only because I know them and have been using them for a while. I have looked into Simplepie, but the FFA scripts do some things that I've seen no obvious solutions for with Simplepie, like limiting the number of items per individual feed (RSSmesh) or limiting the description length (RSS2HTML). -Yahoo! Pipes is out, they cache their data for too long for my application. Should you want to take a look at the code, here are the scripts as txt files. RSS2HTML2 and RSSmesh are the FeedForAll scripts, FeedForAll_XMLParser... is the included parser. Note that I have not yet amended these to handle $argv etc. I have however in "scraper-universal-rss-cli", which works fine with CLI. If anyone has any thoughts to share on this it would be very much appreciated. Thank you in advance.

• Compression algorithm for IEEE-754 data

  - by David Taylor

  Anyone have a recommendation on a good compression algorithm that works well with double precision floating point values? We have found that the binary representation of floating point values results in very poor compression rates with common compression programs (e.g. Zip, RAR, 7-Zip etc). The data we need to compress is a one dimensional array of 8-byte values sorted in monotonically increasing order. The values represent temperatures in Kelvin with a span typically under of 100 degrees. The number of values ranges from a few hundred to at most 64K. Clarifications All values in the array are distinct, though repetition does exist at the byte level due to the way floating point values are represented. A lossless algorithm is desired since this is scientific data. Conversion to a fixed point representation with sufficient precision (~5 decimals) might be acceptable provided there is a significant improvement in storage efficiency. Update Found an interesting article on this subject. Not sure how applicable the approach is to my requirements. http://users.ices.utexas.edu/~burtscher/papers/dcc06.pdf

• How do I work out IEEE 754 64-bit Floating Point Double Precision?

  - by yousef gassar

  enter code herehello i have done it in 32 but i could dont do it in 62bits please i need help I am stuck on this question and need help. I don't know how to work it out. This is the question. Below are two numbers represented in IEEE 754 64-bit Floating Point Double Precision, the bias of the signed exponent is -1023. Any particular real number ‘N’ represented in 64-bit form (i.e. with the following bit fields; 1-bit Sign, 11-bit Exponent, 52-bit Fraction) can be expressed in the form ±1.F2 × 2X by substituting the bit-field values using formula (IV.I): N = (-1) S × 1.F2 × 2(E – 1023) for 0 < E < 2047.........................….(IV.I) Where N= the number represented, S=Sign bit-value, E=Exponent=X +1023, F=Fraction or Mantissa are the values in the 1, 11 and 52-bit fields respectively in the IEEE 754 64-bit FP representation. Using formula (IV.I), express the 64-bit FP representation of each number as: (i) A binary number of the form:- ±1.F2 × 2X (ii) A decimal number of the form:- ±0.F10 × 10Y {limit F10 to 10 decimal places} Sign 0 1 Exponent 1000 0001 001 11 Fraction 1111 0111 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 52 Sign 1 1 Exponent 1000 0000 000 11 Fraction 1001 0010 0001 1111 1011 0101 0100 0100 0100 0010 1101 0001 1000 52 I know I have to use the formula for each of the these but how do I work it out? Is it like this? N = (-1) S × 1.F2 × 2(E – 1023) = 1 x 1.1111 0111 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 x 1000 0001 00111 (-1023)?

• Problem with non blocking fifo in bash

  - by timdel

  Hi! I'm running a few Team Fortress 2 servers and I want to write a little management script. Basically the TF2 servers are a fg process which provides a server console, so I can start the server, type status and get an answer from it: ***@purple:~/tf2$ ./start_server_testing Auto detecting CPU Using AMD Optimised binary. Server will auto-restart if there is a crash. Console initialized. [bla bla bla] Connection to Steam servers successful. VAC secure mode is activated. status hostname: Team Fortress version : 1.0.6.1/15 3883 secure udp/ip : ***.***.133.31:27600 map : ctf_2fort at: 0 x, 0 y, 0 z players : 0 (2 max) # userid name uniqueid connected ping loss state adr Great, now I want to create a script which sends the command sm_reloadadmins to all my servers. The best way I found to do this is using a fifo named pipe. Now what I want to do is having this pipe readonly and non blocking to the server process, so I can write into the pipe and the server executes it, but still I want to write via console one the server, so if I switch back to the fg process of the server and I type status I want an answer printed. I tried this (assuming serverfifo is mkfifo serverfifo): ./start_server_testing < serverfifo Not working, the server won't start until something is written to the pipe. ./start_server_testing <> serverfifo Thats actually working pretty good, I can see the console output of the server and I can write to the fifo and the server executes the commands, but I can't write via console to the server anymore. Also, if I write 'exit' to the pipe (which should end the server) and I'm running it in a screen the screen window is getting killed for some reason (wtf why?). I only need the server to read the fifo without blocking AND all my keyboard input on the server itself should be send to the server AND all server ouput should be written to the console. Is that possible? If yes, how?

• How to keep unreachable code?

  - by Gabriel

  I'd like to write a function that would have some optional code to execute or not depending on user settings. The function is cpu-intensive and having ifs in it would be slow since the branch predictor is not that good. My idea is making a copy in memory of the function and replace NOPs with jumps when I don't want to execute some code. My working example goes like this: int Test() { int x = 2; for (int i=0 ; i<10 ; i++) { x *= 2; __asm {NOP}; // to skip it replace this __asm {NOP}; // by JMP 2 (after the goto) x *= 2; // Op to skip or not x *= 2; } return x; } In my test's main, I copy this function into a newly allocated executable memory and replace the NOPs by a JMP 2 so that the following x *= 2 is not executed. The problem is that I would have to change the JMP operand every time I change the code to be skipped. An alternative that would fix this problem would be: __asm {NOP}; // to skip it replace this __asm {NOP}; // by JMP 2 (after the goto) goto dont_do_it; x *= 2; // Op to skip or not dont_do_it: x *= 2; This way, as a goto uses 2 bytes of binary, I would be able to replace the NOPs by a fixed JMP of alway 2 in order to skip the goto. Unfortunately, in full optimization mode, the goto and the x*=2 are removed because they are unreachable at compilation time. Hence the need to keep that dead code.
