• How test a Delphi app with Application Verifier 4.0?

  - by mamcx

  I download the Application Verifier 4.0 to test my App for check if could have problems on Vista/7. I run from Delphi 2010 debugger, and stop in CPU view. Obviously, I don't understand anything about assembler!. So, I try running directly from the windows explorer, and the App die. (In fact, I don't understand well what exactly will do App Verifier: I expect some kind of friendly message). This is what i get: 7C81A3E2 C3 ret 7C81A3E3 90 nop 7C81A3E4 8BFF mov edi,edi ntdll.DbgUserBreakPoint: 7C81A3E6 CC int 3 7C81A3E7 C3 ret 7C81A3E8 8BFF mov edi,edi 7C81A3EA 8B442404 mov eax,[esp+$04] 7C81A3EE CC int 3 7C81A3EF C20400 ret $0004 ntdll.NtCurrentTeb: 7C81A3F2 64A118000000 mov eax, fs:[$00000018] 7C81A3F8 C3 ret ntdll.RtlInitString: 7C81A3F9 57 push edi Loading: :7c81a3e2 ntdll.DbgBreakPoint + 0x1 :10003b68 ; C:\WINDOWS\system32\vrfcore.dll :00396a9d ; C:\WINDOWS\system32\vfbasics.dll :00397316 ; C:\WINDOWS\system32\vfbasics.dll :7c84bcdb ; ntdll.dll :7c8316f8 ; ntdll.dll :7c83154f ; ntdll.dll :7c82855e ntdll.KiUserExceptionDispatcher + 0xe :0040aa00 GetUILanguages + $80 :0040b298 GetResourceModuleName + $124 :0040afde LoadResourceModule + $7A :0040a134 DelayLoadResourceModule + $2C :00406c40 @StartExe + $44 :77e6f23b ; C:\WINDOWS\system32\KERNEL32.dll

• Locating memory leak in Apache httpd process, PHP/Doctrine-based application

  - by Sam

  I have a PHP application using these components: Apache 2.2.3-31 on Centos 5.4 PHP 5.2.10 Xdebug 2.0.5 with Remote Debugging enabled APC 3.0.19 Doctrine ORM for PHP 1.2.1 using Query Caching and Results Caching via APC MySQL 5.0.77 using Query Caching I've noticed that when I start up Apache, I eventually end up 10 child processes. As time goes on, each process will grow in memory until each one approaches 10% of available memory, which begins to slow the server to a crawl since together they grow to take up 100% of memory. Here is a snapshot of my top output: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1471 apache 16 0 626m 201m 18m S 0.0 10.2 1:11.02 httpd 1470 apache 16 0 622m 198m 18m S 0.0 10.1 1:14.49 httpd 1469 apache 16 0 619m 197m 18m S 0.0 10.0 1:11.98 httpd 1462 apache 18 0 622m 197m 18m S 0.0 10.0 1:11.27 httpd 1460 apache 15 0 622m 195m 18m S 0.0 10.0 1:12.73 httpd 1459 apache 16 0 618m 191m 18m S 0.0 9.7 1:13.00 httpd 1461 apache 18 0 616m 190m 18m S 0.0 9.7 1:14.09 httpd 1468 apache 18 0 613m 190m 18m S 0.0 9.7 1:12.67 httpd 7919 apache 18 0 116m 75m 15m S 0.0 3.8 0:19.86 httpd 9486 apache 16 0 97.7m 56m 14m S 0.0 2.9 0:13.51 httpd I have no long-running scripts (they all terminate eventually, the longest being maybe 2 minutes long), and I am working under the assumption that once each script terminates, the memory it uses gets deallocated. (Maybe someone can correct me on that). My hunch is that it could be APC, since it stores data between requests, but at the same time, it seems weird that it would store data inside the httpd process. How can I track down which part of my app is causing the memory leak? What tools can I use to see how the memory usage is growing inside the httpd process and what is contributing to it?

• Python MD5 Hash Faster Calculation

  - by balgan

  Hi everyone. I will try my best to explain my problem and my line of thought on how I think I can solve it. I use this code for root, dirs, files in os.walk(downloaddir): for infile in files: f = open(os.path.join(root,infile),'rb') filehash = hashlib.md5() while True: data = f.read(10240) if len(data) == 0: break filehash.update(data) print "FILENAME: " , infile print "FILE HASH: " , filehash.hexdigest() and using start = time.time() elapsed = time.time() - start I measure how long it takes to calculate an hash. Pointing my code to a file with 653megs this is the result: root@Mars:/home/tiago# python algorithm-timer.py FILENAME: freebsd.iso FILE HASH: ace0afedfa7c6e0ad12c77b6652b02ab 12.624 root@Mars:/home/tiago# python algorithm-timer.py FILENAME: freebsd.iso FILE HASH: ace0afedfa7c6e0ad12c77b6652b02ab 12.373 root@Mars:/home/tiago# python algorithm-timer.py FILENAME: freebsd.iso FILE HASH: ace0afedfa7c6e0ad12c77b6652b02ab 12.540 Ok now 12 seconds +- on a 653mb file, my problem is I intend to use this code on a program that will run through multiple files, some of them might be 4/5/6Gb and it will take wayy longer to calculate. What am wondering is if there is a faster way for me to calculate the hash of the file? Maybe by doing some multithreading? I used a another script to check the use of the CPU second by second and I see that my code is only using 1 out of my 2 CPUs and only at 25% max, any way I can change this? Thank you all in advance for the given help.

• ABAddressBookGetPersonCount(ab) problem

  - by prathumca

  Why the call to ABAddressBookGetPersonCount(ab); is giving the problem? I have around 2000 contacts in my address book. When my app gets started I'm trying to read the entire address book. This works perfectly on simulator but causing crash on IPhone. The crash report is pointing to 9 AppSupport 0x31fbca1e 0x31fb6000 + 27166 // CPRecordStoreGetCountOfInstancesOfClassWhere + 0x7e 10 AddressBook 0x318df668 0x318d5000 + 42600 // ABCGetPersonCountInStore + 0x88 11 AddressBook 0x318ea450 0x318d5000 + 87120 // ABAddressBookGetPersonCount + 0x8 12 MyAddressBook 0x0000ad30 0x1000 + 40240 // -[MyAddressBookController readAB] + 0x2c0 13 MyAddressBook 0x0000a8ce 0x1000 + 39118 // -[MyAddressBookController start] + 0x4a What I'm doing in "readAB"? - (void) readAB { ABAddressBookRef ab = ABAddressBookCreate(); CFArrayRef contacts = ABAddressBookCopyArrayOfAllPeople(ab); CFIndex count = ABAddressBookGetPersonCount(ab); for(int i = 0; i < count; i++) { //doing some thing... } } If you observe the above crash report, it is clearly pointing to CFIndex count = ABAddressBookGetPersonCount(ab);. Whats wrong with this code? I'm sure that this code works perfectly on firmware 3.1.2. But now I upgraded firmware to 3.1.3. Is this upgrade is causing any trouble? Regards, prathumca.

• using JQuery and Prototype in the same page

  - by Don

  Hi, Several of my pages use both JQuery and Protoype. Since I upgraded to version 1.3 of JQuery this appears to be causing problems, because both libraries define a function named '$'. JQuery provides a function noConflict() which relinquishes control of $ to other libraries that may be using it. So it seems like I need to go through all my pages that look like this: <head> <script type="text/javascript" src="/obp/js/prototype.js"></script> <script type="text/javascript" src="/obp/js/jquery.js"></script> </head> and change them to look like this: <head> <script type="text/javascript" src="/obp/js/prototype.js"></script> <script type="text/javascript" src="/obp/js/jquery.js"></script> <script type="text/javascript"> jQuery.noConflict(); var $j = jQuery; </script> </head> I should then be able to use '$' for Prototype and '$j' (or 'jQuery') for JQuery. I'm not entirely happy about duplicating these 2 lines of code in every relevant page, and expect that at some point somebody is likely to forget to add them to a new page. I'd prefer to be able to do the following Create a file jquery-noconflict.js which "includes" jquery.js and the 2 lines of code shown above Import jquery-noconflict.js (instead of jquery.js) in all my JSP/HTML pages However, I'm not sure if it's possible to include one JS file in another, in the manner I've described? Of course an alternate solution is simply to add the 2 lines of code above to jquery.js directly, but if I do that I'll need to remember to do it every time I upgrade JQuery. Thanks in advance, Don

• Windows with Plesk Panel installs ActiveState Python 2.5.0 - any thoughts?

  - by B Mahoney

  I expect to run Pylons on a Windows Server 2003 and IIS 6 on a Virtual Private Server (VPS). Most work with the VPS is done through the Plesk 8.6 panel. The Plesk panel has a lot of maintenance advantages for us. However, this Plesk configuration installs ActiveState Python 2.5.0. The Parallels Plesk documents for 8.6 and version 9 insist that only this configuration should be installed. I'm not eager to settle for the baseline 2.5.0. but don't see any safe upgrade path. How has ActiveState Python 2.5.0 been for other users? Can you replace the Parallels\Plesk\Additional\Python with another distribution? I don't want to break Plesk, please. Previously, I followed these instructions, Serving a Pylons app with IIS - Pylons Cookbook Using the default web site IP address, I had Python 2.6.3 installing the ISAPI-WSGI dll in IIS so that I successfully ran Pylons in a virutalenv through IIS using the IP address, no domain name. I would be so happy if I could run this successful configuration for my domains while I must use Plesk. Tips and solutions appreciated.

• "The binary you uploaded was invalid. the file was not a valid zip file" Error message uploading app

  - by Keith Loughnane

  Hi, I'm trying to upload an iPhone app binary to iTunesConnect and keep getting the following error message "The binary you upload was invalid. the file was not a valid zip file". I had an app upload ok recently but this app is having problems. So after a while I carefully went through the following steps trying to make sure everything was ok. Any help is appreciated. The steps: renamed the project (Project-Rename... enter name into Rename project to:) to release name making sure the name has no spaces. Cleaned project Make sure references in build setting reflect new app name Create new app ID matching project name in iPhone Provisioning Portal Destroyed old developer and distributer provisioning profiles in Provisioning Portal, in XCode and on iPhone. Create new development provisioning profile using new app name. Install development provisioning profile into XCode 8) Build (Release) for iPhone OS 3.1.3 (highest my phone will upgrade to, I'm assuming current released version) Builds, Installs and Runs on actual iPhone: To me this implys App and developer ID's are OK. Create a distributor provisioning profile using existing Distributer ID. Install distributer ID into XCode Clean Checked that "Code Signing Identity" and "Any iPhone OS Device" lines in Build settings are set to Distributor ID Build for release for OS 3.1.3 Check Build results to make sure code is signed with Distributor Profile Reveal .app file and compress (alt click Compress "appName.app") Upload to iTunes connect Gives "The binary you uploaded was invalid.

• What's the largest (most complex) PHP algorithm ever implemented in a single monolithic PHP script?

  - by Alex R

  I'm working on a tool which converts PHP code to Scala. As one of the finishing touches, I'm in need of a really good (er, somewhat biased) benchmark. By dumb luck my first benchmark attempt was with some code which uses bcmath extensively, which unfortunately is 1000x slower in Java, making the Scala code 22x slower overall than the original PHP. So I'm looking for some meaningful PHP benchmark with the following characteristics: The source needs to be in a single file. I need it to be simple to setup - no databases, hard-to-find input files, etc. Simple text input and output preferred. It should not use features that are slow in Java (BigInteger, trigonometric functions, etc). It should not use exoteric or dynamic PHP functions (e.g. no "eval" or "variable vars"). It should not over-rely on built-in libraries, e.g. MD5, crypt, etc. It should not be I/O bound. A CPU-bound memory-hungry algorithm is preferred. Basically, intensive OO operations, integer and string manipulation, recursion, etc would be great. Thanks

• WiX: Forcefully launch uninstall previous using CustomAction

  - by leiflundgren

  I'm writing a new major upgrade of our product. In my installer I start by finding configuration settings of the previous version, then I'd like to uninstall the previous version. I have found several guides telling me how one should make a MSI suitable for such upgrades. However, the previous was not an MSI. It was not according to best practices. It does, however, in registry HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall{GUID} specify an UninstallString. Using a RegistrySearch I can easy find the command below, which I store in UNINSTALL_CMD. RunDll32 C:\PROGRA~1\COMMON~1\INSTAL~1\PROFES~1\RunTime\10\01\Intel32\Ctor.dll,LaunchSetup "C:\Program Files\InstallShield Installation Information\{GUID}\setup.exe" -l0x9 -removeonly 4: I cannot get the hang of the CustomAction needed to perform the actual uninstall. <CustomAction Id="ca.UninstPrev" Property="UNINSTALL_CMD" ExeCommand="" /> The MSI logs says: Info 1721. There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor.

• Should I move big data blobs in JSON or in separate binary connection?

  - by Amagrammer

  QUESTION: Is it better to send large data blobs in JSON for simplicity, or send them as binary data over a separate connection? If the former, can you offer tips on how to optimize the JSON to minimize size? If the latter, is it worth it to logically connect the JSON data to the binary data using an identifier that appears in both, e.g., as "data" : "< unique identifier " in the JSON and with the first bytes of the data blob being < unique identifier ? CONTEXT: My iPhone application needs to receive JSON data over the 3G network. This means that I need to think seriously about efficiency of data transfer, as well as the load on the CPU. Most of the data transfers will be relatively small packets of text data for which JSON is a natural format and for which there is no point in worrying much about efficiency. However, some of the most critical transfers will be big blobs of binary data -- definitely at least 100 kilobytes of data, and possibly closer to 1 megabyte as customers accumulate a longer history with the product. (Note: I will be caching what I can on the iPhone itself, but the data still has to be transferred at least once.) It is NOT streaming data. I will probably use a third-party JSON SDK -- the one I am using during development is here. Thanks

• Response.Redirect in a COM+ Object Called from Classic ASP Page

  - by ajdams

  Basically we moved from IIS 5 to IIS 7 and I am trying to update some of our old COM objects to .NET by rewriting them in C#. What I am have so far is a Classic ASP page calling the COM+ object and then I am trying to do a simple redirect within the COM+ object (this is just for testing purposes, it's not what the object will do eventually). My problem/question is, why does the redirect call not work properly? Am I doing something wrong or can you not redirect within a COM+ object? All that happens is a blank white page comes up and if I check the IIS logs, I see no errors. Here is my code so far: In Classic ASP (the call to COM+) Set oBankReg = CreateObject("BVSRegistration.SignIn") oBankReg.GetBankId(bankid) Code in C# COM object: using System; using System.Web; using System.Text; using System.EnterpriseServices; using System.Collections.Generic; using System.Runtime.InteropServices; [assembly: ApplicationName("BVSRegistration")] [assembly: Description("COM+ upgrade of the BVSRegistration VB6 SignIn.cls.")] [assembly: ApplicationActivation(ActivationOption.Server)] [assembly: ApplicationAccessControl(false, AccessChecksLevel = AccessChecksLevelOption.ApplicationComponent)] namespace BVSRegistration { public class SignIn : ServicedComponent { public void GetBankId(string bankid) { HttpContext.Current.Response.Redirect("http://www.google.com"); } } } Any ideas?

• Locating memory leak in Apache httpd process, PHP/Doctrine-based application

  - by Sam

  I have a PHP application using these components: Apache 2.2.3-31 on Centos 5.4 PHP 5.2.10 Xdebug 2.0.5 with Remote Debugging enabled APC 3.0.19 Doctrine ORM for PHP 1.2.1 using Query Caching and Results Caching via APC MySQL 5.0.77 using Query Caching I've noticed that when I start up Apache, I eventually end up 10 child processes. As time goes on, each process will grow in memory until each one approaches 10% of available memory, which begins to slow the server to a crawl since together they grow to take up 100% of memory. Here is a snapshot of my top output: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1471 apache 16 0 626m 201m 18m S 0.0 10.2 1:11.02 httpd 1470 apache 16 0 622m 198m 18m S 0.0 10.1 1:14.49 httpd 1469 apache 16 0 619m 197m 18m S 0.0 10.0 1:11.98 httpd 1462 apache 18 0 622m 197m 18m S 0.0 10.0 1:11.27 httpd 1460 apache 15 0 622m 195m 18m S 0.0 10.0 1:12.73 httpd 1459 apache 16 0 618m 191m 18m S 0.0 9.7 1:13.00 httpd 1461 apache 18 0 616m 190m 18m S 0.0 9.7 1:14.09 httpd 1468 apache 18 0 613m 190m 18m S 0.0 9.7 1:12.67 httpd 7919 apache 18 0 116m 75m 15m S 0.0 3.8 0:19.86 httpd 9486 apache 16 0 97.7m 56m 14m S 0.0 2.9 0:13.51 httpd I have no long-running scripts (they all terminate eventually, the longest being maybe 2 minutes long), and I am working under the assumption that once each script terminates, the memory it uses gets deallocated. (Maybe someone can correct me on that). My hunch is that it could be APC, since it stores data between requests, but at the same time, it seems weird that it would store data inside the httpd process. How can I track down which part of my app is causing the memory leak? What tools can I use to see how the memory usage is growing inside the httpd process and what is contributing to it?

• Selenium and Firefox 9's "Will you help improve Mozilla Firefox" popup

  - by Rup

  I'm trying to test a Java web app using Selenium 2.16.1. When Selenium opens Firefox, I see a band at the top of the page with message "Will you help improve Mozilla Firefox" For some reason this breaks selenium.click("id=submit"); selenium.waitForPageToLoad("60000"); which is trying to log in - it becomes a no-op, and the test fails because it's then expecting to have logged in. If I break on the click line and clear the 'will you help' band before continuing then the form submit succeeds. Is there a way to suppress this band from appearing? (I expect that would mean setting a property in Firefox's default profile - where do I find that?) Or is there a way to get Selenium to spot and dismiss this first? Thanks! I'm using Firefox 9.0.1. Solved - thanks Danny! Just in case it isn't clear from the answers and comments below: This was an issue with 2.16.1 and IMO the best solution is to upgrade to 2.17 or later.

• Porting an IBXpress Interbase 6 app to the current Firebird platform, on Delphi 7?

  - by robsoft

  Just wondering if there are any gotchas to be wary of here. We have a legacy D7 app that we developed several years ago for a client, which uses IBXpress to talk to the open source Interbase 6 build. We're having a number of issues with that platform these days (very slow to connect/start-up on new hardware being the chief one) and the client has okayed spending some time/money moving the database over to Firebird. We really DON'T want to embark upon moving it to D2010 (or D2007 which would be my preference right now) as we figure that we might have to move the database layer from IBXpress to something else to best suit Firebird anyway. And at the end of the day, the client is only looking to lessen the database pain, not overhaul/upgrade/rewrite the app. Given the ancestry of Firebird, is it a fairly painless, well-understood path from IBXpress Interbase 6 to (whatever) with Firebird? We have quite a number of sprocs, triggers (and even datatypes) etc in the existing IB database already (and the client has a number of paying customers all using this platform) so we felt that going to Firebird was more likely to be a smoother move than moving to SQL Express (or another flavour of DB entirely). Note that we're not looking for 'embedded' DB advocacy - in many of our client's customers' installations, the software is used in a multi-user client-server way so keeping that kind of approach is important.

• Calculate shortest path through a grocery store

  - by Bart

  Hi, I'm trying to find a way to find the shortest path through a grocery store, visiting a list of locations (shopping list). The path should start at a specified startposition and can end at multiple endpositions (there are multiple checkout counters). Also, I have some predefined constraints on the path, such as "item x on the shopping list needs to be the last, second last, or third last item on the path". There is a function that will return true or false for a given path. Finally, this needs to be calculated with limited cpu power (on a smartphone) and within a second or so. If this isn't possible, then an approximation to the optimal path is also ok. Is this possible? So far I think I need to start by calculating the distance between every item on the list using something like A* or Dijkstra's. After that, should I treat it like the travelling salesman problem? Because in my problem there is a specified startnode, specified endnodes, and some constraints, which are not in the travelling salesman problem. Any help would be appreciated :)

• A copy of ApplicationController has been removed from the module tree but is still active

  - by Matchu

  Whenever two concurrent HTTP requests go to my Rails app, the second always returns the following error: A copy of ApplicationController has been removed from the module tree but is still active! From there it gives an unhelpful stack trace to the effect of "we went through the standard server stuff, ran your first before_filter on ApplicationController (and I checked; it's just whichever filter runs first)", then offers the following: /home/matchu/rails/torch/vendor/rails/activesupport/lib/active_support/dependencies.rb:414:in `load_missing_constant' /home/matchu/rails/torch/vendor/rails/activesupport/lib/active_support/dependencies.rb:96:in `const_missing' which I'm assuming is a generic response and doesn't really say much. Google seems to tell me that people developing Rails Engines will encounter this, but I don't do that. All I've done is upgrade my Rails app from 2.2 (2.1?) to 2.3. What are some possible causes for this error, and how can I go about tracking down what's really going on? I know this question is vague, so would any other information be helpful? More importantly: I tried doing a test run in a "production" environment just now, and the error doesn't seem to persist. Does this only affect development, then, and need I not worry too much?

• asynchronous pages

  - by lockedscope

  I have just read the multi-threading and custom threading in asp.net articles. http://www.williablog.net/williablog/post/2008/12/16/Custom-Threading-in-ASPNET.aspx http://www.williablog.net/williablog/post/2008/12/16/Multi-Threading-in-ASPNET.aspx I have couple of questions. What does he mean by returning a thread to the pool? Is that thread completely removed from memory or put in to a state that it does not scheduled to CPU(is it in sleep state or whatever)? If that thread is removed from memory how could it survive after async point? How this mechanism works? Are every objects(pages class, request,response etc.) are copied to somewhere else before they are disposed? (Or, is it just waiting in a sleep state and then its waked when async call ends?) He is saying that; "Having said that, making pages asynchronous is not really about improving performance, it is about improving scalability" then he is saying; "I'm sorry to say that it will do nothing for scalability or performance." So which one is true? or for which case(s) are they true?

• Slow MySQL Query not using filesort

  - by Canadaka

  I have a query on my homepage that is getting slower and slower as my database table grows larger. tablename = tweets_cache rows = 572,327 this is the query I'm currently using that is slow, over 5 seconds. SELECT * FROM tweets_cache t WHERE t.province='' AND t.mp='0' ORDER BY t.published DESC LIMIT 50; If I take out either the WHERE or the ORDER BY, then the query is super fast 0.016 seconds. I have the following indexes on the tweets_cache table. PRIMARY published mp category province author So i'm not sure why its not using the indexes since mp, provice and published all have indexes? Doing a profile of the query shows that its not using an index to sort the query and is using filesort which is really slow. possible_keys = mp,province Extra = Using where; Using filesort I tried adding a new multie-colum index with "profiles & mp". The explain shows that this new index listed under "possible_keys" and "key", but the query time is unchanged, still over 5 seconds. Here is a screenshot of the profiler info on the query. http://i355.photobucket.com/albums/r469/canadaka_bucket/slow_query_profile.png Something weird, I made a dump of my database to test on my local desktop so i don't screw up the live site. The same query on my local runs super fast, milliseconds. So I copied all the same mysql startup variables from the server to my local to make sure there wasn't some setting that might be causing this. But even after that the local query runs super fast, but the one on the live server is over 5 seconds. My database server is only using around 800MB of the 4GB it has available. here are the related my.ini settings i'm using default-storage-engine = MYISAM max_connections = 800 skip-locking key_buffer = 512M max_allowed_packet = 1M table_cache = 512 sort_buffer_size = 4M read_buffer_size = 4M read_rnd_buffer_size = 16M myisam_sort_buffer_size = 64M thread_cache_size = 8 query_cache_size = 128M # Try number of CPU's*2 for thread_concurrency thread_concurrency = 8 # Disable Federated by default skip-federated key_buffer = 512M sort_buffer_size = 256M read_buffer = 2M write_buffer = 2M key_buffer = 512M sort_buffer_size = 256M read_buffer = 2M write_buffer = 2M

• Weird Issues with WPMU I Can't Figure Out

  - by HollerTrain

  I know I should post this on the WPMU forum, but no one writes me back and I'm just trying to find a larger audience hoping you have run into this issue as well. I have built a WPMU site for a client, and I am able to upload media into the Media Library and within a Post or Page perfectly. I thought my job was finished, yet the client can't upload any media at all. I'm located in Kentucky, they are located in New England (if that even matters). I had the client record their process of uploading as I thought they were simply not following my instructions for uploading, yet they are doing everything correctly. When uploading a file it goes through the process of allowing them to select a file and it says it uploads it, yet when it is finished uploading nothing is in the Media Library or in the Post. Video of the client trying to upload in Media Manager (http://www.screencast.com/users/CatherineWeber/folders/Jing/media/945d33fa-a752-45fd-9bc1-f76fc5a1814a) Video of the client trying to upload within a Post (http://www.screencast.com/users/CatherineWeber/folders/Jing/media/b5c60e25-f0b5-40c0-a820-c2fc9eb00906) Asking the client to disable Flash Uploader didn't work :( Yet, I can login to the WPMU site, access their blog's backend and can easily upload a ton of files. I am so lost at to what the issue is here. I am running version 2.8.4a, and will try to upgrade to latest release hoping this will fix things.

• Getting hardware floating point with android NDK

  - by Goz

  Hi All, I've begun playing with the android NDK. One of the things I've just learnt is about creating an application.mk file to specify the armv7 abi. I'm building the san-angeles example with the following parameters. APP_MODULES := sanangeles APP_PROJECT_PATH := $(call my-dir)/../ APP_OPTIM := release APP_ABI := armeabi-v7a However this seems to run at exactly the same speed as it did before (ie badly). Am I just GL limited and not CPU limited or is something wrong here? I have noticed when I compile that I get the following command line options emitted: -march=armv7-a -mfloat-abi=softfp -mfpu=vfp -mthumb The thing that worries me there is the "softfp". There IS mention of the v7 abi, the VFP fpu stuff and I'm guessing the "thumb" refers to the "thumb-2" instructions (Though I don't know what exactly these are). However that "softfp" does concern me. Shouldn't it be "hardfp"? Anyone got any ideas on these questions? I think I'm probably about ready to start implementing some GL ES 2.0 code for my HTC Desire but I'd like to make sure I'm getting the best possible speed out of it :) Cheers in advance!

• How can I open VLC via browser with PHP (Mac OS X)

  - by Damiqib

  I'm trying to open VLC via browser and make it instantly play the given video file on Mac OS X. This runs on my local server and is only meant to run locally - therefore I already run apache (MAMP) with my username and with group "staff" (defined in httpd.conf). YES - I do know that VLC has http interface - however that is not what I need, so do not suggest that... My current system works without any problems when I run it via Terminal: php /var/www/Movies/index.php - This leads to VLC opening and video starts playing fullscreen like intented. Problems start when I run the same PHP-page with browser. Then the VLC-process starts, but there's no GUI for it, video file won't start playing and the VLC-process takes nearly 100% of CPU. Both; terminal and browser started VLC-processes run with the same user (mine) Both have "Parent process" bash VLC-process begun with Terminal has empty "Process group" (only process id-number) and browser started has "httpd" + (id-number) VLC-process started via browser makes 1000-times more "Mach System Calls" than it's Terminal-started counterpart. Could anyone give me any pointers on how to get this thing working? index.php # $j is a file path to the videofile and is defined before exec('/var/www/Movies/vlc.sh "' . $j . '" > /dev/null 2>&1 & echo $!;'); # If I do this in the given PHP-page it tells me that apache is running # with my username and with the group "staff" like it should be... exec('whoamI'); vlc.sh #!/bin/bash # Activate VLC in 5 seconds to make it the front-most window (sleep 5; open -a VLC) & # Open video file /Applications/VLC.app/Contents/MacOS/VLC --quiet --fullscreen "$1"

• Shared classes are build under VS2008 only but not under MSBuild.

  - by Vasiliy Borovyak

  We share our classes between silverlight 3.0 client and server as is it described here. Everything works fine under Visual Studio 2008 only. Using msbuild with following command line parameters: C:\Windows\Microsoft.NET\Framework\v3.5\msbuild.exe FoobarApplication.sln /t:Rebuild /p:Configuration=Release /p:Platform="Any CPU" we get following error: Class1.cs(28,54): error CS0234: The type or namespace name 'WcfService' does not exist in the namespace 'Company.FoobarApplication' (are you missing an assembly reference?) Service References\geoServiceReference1\Reference.cs(24,81): error CS0234: The type or namespace name 'WcfService' does not exist in the namespace 'Company.FoobarApplication' (are you missing an assembly reference?) Done Building Project "C:\work\bov-tmp\FoobarApplication\SilverlightClassLibrary3\SilverlightClassLibrary3.csproj" (Rebuild target(s)) -- FAILED. Done Building Project "C:\work\bov-tmp\FoobarApplication\FoobarApplication.sln" (Rebuild target(s)) -- FAILED. I found exactly the same question here. There are 4 workarounds there, I tried first 3 of them and those did not worked out. The 4-th workaround is not the acceptable solution. Any thoughts how to build the solution?

• C & MinGW: Hello World gives me the error "programm too big to fit in memory"

  - by user1692088

  I'm new here. Here's my problem: I installed MinGW on my Windows 7 Home Premium 32-bit Netbook with Intel Atom CPU N550, 1.50GHz and 2GB RAM. Now I made a file named hello.h and tried to compile it via CMD with the following command: "gcc c:\workspace\c\helloworld\hello.h -o out.exe" It compiles with no error, but when I try to run out.exe, it gives me following error: "program too big to fit in memory" Things I have checked: I have added "C:\MinGW\bin" to the Windows PATH Variable I have googled for about one hour, but ever since I'm a newbie, I can't really figure out what the problem is. I have compiled the same code on my 64-bit machine, compiles perfectly, but cannot be run due to 64-bit <- 16-bit problematic. I'd really appreciate, if someone could figure out, what the problem is. Btw, here's my hello.h: #include <stdio.h> int main(void){ printf("Hello, World\n"); } ... That's it. Thanks for your replies. Cheers, Boris

• Python SQLite FTS3 alternatives?

  - by Mike Cialowicz

  Are there any good alternatives to SQLite + FTS3 for python? I'm iterating over a series of text documents, and would like to categorize them according to some text queries. For example, I might want to know if a document mentions the words "rating" or "upgraded" within three words of "buy." The FTS3 syntax for this query is the following: (rating OR upgraded) NEAR/3 buy That's all well and good, but if I use FTS3, this operation seems rather expensive. The process goes something like this: # create an SQLite3 db in memory conn = sqlite3.connect(':memory:') c = conn.cursor() c.execute('CREATE VIRTUAL TABLE fts USING FTS3(content TEXT)') conn.commit() Then, for each document, do something like this: #insert the document text into the fts table, so I can run a query c.execute('insert into fts(content) values (?)', content) conn.commit() # execute my FTS query here, look at the results, etc # remove the document text from the fts table before working on the next document c.execute('delete from fts') conn.commit() This seems rather expensive to me. The other problem I have with SQLite FTS is that it doesn't appear to work with Python 2.5.4. The 'CREATE VIRTUAL TABLE' syntax is unrecognized. This means that I'd have to upgrade to Python 2.6, which means re-testing numerous existing scripts and programs to make sure they work under 2.6. Is there a better way? Perhaps a different library? Something faster? Thank you.
