• PHP File unreadable after being downloaded

  - by Drew

  Hi I have a script that creates a file and stores it on the server. The file is encoded in UTF-8 and is a kind of xml file for the cmap software. If i open the file directly from the server then there is no problem and the file can be read. I am forcing a download of this file when a user goes to a specific url. After such a download, the file is unreadable by the cmap software. I have to go into my text editor (notepad++) and change the encoding from UTF-8 to UTF-8 without BOM. Am I sending the wrong headers? Is php doing something to the file when it is downloading it? Any advice on this would really be appreciated. Cheers Drew

• Style: Dot notation vs. message notation in Objective-C 2.0

  - by groundhog

  In Objective-C 2.0 we got the "dot" notation for properties. I've seen various back and forths about the merits of dot notation vs. message notation. To keep the responses untainted I'm not going to respond either way in the question. What is your thought about dot notation vs. message notation for property accessing? Please try to keep it focused on Objective-C - my one bias I'll put forth is that Objective-C is Objective-C, so your preference that it be like Java or JavaScript aren't valid. Valid commentary is to do with technical issues (operation ordering, cast precedence, performance, etc), clarity (structure vs. object nature, both pro and con!), succinctness, etc. Note, I'm of the school of rigorous quality and readability in code having worked on huge projects where code convention and quality is paramount (the write once read a thousand times paradigm).

• Reading inputs in java

  - by Gandalf StormCrow

  Hello everyone I'm trying to improve my Java skills by solving some problems from ACM, now the thing is my sample input looks like this : 3 100 34 100 75 250 27 2147483647 101 304 101 303 -1 -1 So at first I'm just trying to read them but its not working here is the java code: import java.io.BufferedInputStream; import java.util.Scanner; public class Main { public static void main(String args[]) { Scanner stdin = new Scanner(new BufferedInputStream(System.in)); while (stdin.hasNext()) { System.out.println(stdin.nextInt() + " and the next " + stdin.nextInt()); } } } I'm trying to send these inputs as an argument, and not by reading them from file, here is how: The program just spins(executes) but not printing anything. How can I fix this?

• Message Queue or Scheduler

  - by Walter White

  Hi all, I am currently using Quartz Scheduler for asynchronous tasks such as sending an email when an exception occurs, sending an email from the web interface, or periodically analyzing traffic. Should I use a message queue for sending an email? Is it any more efficient or correct to do it that way? The scheduler approach works just fine. If I use a queue and the email failed to send, is it possible for the queue to retry sending the email at a later time? The queue approach looks simpler than the scheduler for tasks that need to happen immediately, but for scheduler tasks, the scheduler still, unless there is more to the queue than I am aware of. I have not yet used JMS, so this is what I have read. Walter

• A very weired problem with texbox control in C# .net

  - by Kazoom

  Well i know textbox is a very simple user control, perhaps the first input control ever made. I have been facing a very frustrating problem with this simple control. I programatically add a textbox in my user control. From ui i am able to edit it like a normal textbox. however, i am not able to read the user inputed value in the program. my program all the time sees the old value with which my text box was initialized. i textchange event getting triggered but the value never gets updated. This seemingly looks to be some innocuous bug in the code, but the program is very simple and it does not seem to be having any bug. Any guidelines on this issue?

• How to split a string by ',' or '[|]' unless the ',' is in '{}'

  - by floyddotnet

  i search for a regex to split the following string: aaa[bbb,ccc[ddd,{eee:1,mmm:999}],nnn[0,3]] aaa[bbb,ccc[ddd,{eee:1, mmm:[123,555]}],nnn[0,3]] aaa[bbb, ccc[ddd, ddd],nnn[0,3]] aaa[bbb,ddd[0,3]] by '[' or ']' or ',' unless the ',' is in '{}'. As example: split 'aaa[bbb,ccc[ddd,' to aaa, bbb, ccc, ddd is allow but not {eee:1,mmm:999}. the result: aaa, bbb, ccc, ddd, {eee:1,mmm:999}, nnn, 0, 3 aaa, bbb, ccc, ddd, {eee:1, mmm:[123,555]}], nnn, 0, 3 aaa, bbb, ccc, ddd, ddd, nnn, 0, 3 aaa, bbb, ddd, 0, 3 i have read meany other questions but i cant modifie the regex's there are post to do this what i want. the target language for the expression is javascript.

• Is it possible to stream a file to and from servers without holding the data in ram?

  - by Chris Denman

  Hi everyone! PHP question (new to PHP after 10 years of Perl, arrggghhh!). I have a 100mb file that I want to send to another server. I have managed to read the file in and "post" it without curl (cannot use curl for this app). Everything is working fine on smaller files. However, with the larger files, PHP complains about not being able to allocate memory. Is there a way to open a file, line by line, and send it as a post ALSO line by line? This way nothing is held in ram thus preventing my errors and getting around strict limitations. Chris

• “Could not create the file”, “Access is denied” and “Unrecoverable build error” in building setup project in VS 2008

  - by Mister Cook

  When building a setup project I get a message: Error with setup build: Error 27 Could not create the file 'C:\Users\MyName\AppData\Local\Temp\VSI1E1A.tmp' 'Access is denied.' I have tried the following (from http://support.microsoft.com/kb/329214/EN-US) regsvr32 "C:\Program Files (x86)\Common Files\Microsoft Shared\MSI Tools\mergemod.dll" The DLL registers but this does not fix my problem. Also, I tried a Clean build, deleting the temp folder, ran VS2008 as administratror, restart my PC but it occurs every time. I have no anti-virus software running and running on Windows 7 64-bit. This operation worked fine until recently. I have read many other users see this but found no solution. The only half solution I found was to edit setup properties and switch to Package files as Loose uncompressed files. This works but is not ideal as I need a full installer.

• Problem with Gallio and TeamCity and the new Visual Studio 2010 release

  - by Bernard Larouche

  I am running TeamCity on a virtual machine. I have installed the new Visual Studio 2010 release yesterday and converted my VS 2008 projects. I also have installed .NET Framework 4 on my virtual machine. Before yesterday all my projects were building succesfully on the CI server but since I installed VS 2010 I get the following error message : error MSB5014: File format version is not recognized. MSBuild can only read solution files between versions 7.0 and 9.0, inclusive. I did change my config on Team City to take into account the new .NET 4 framework : Build Runner : MSBuild Build File Path : CFT.msbuild MSBuild version : Microsoft.NET Framework 4.0 MSBuild ToolsVersion : 4.0 Run Platform : x86 I think it has something to do with the fact that now MSBuild must refer to .NET 4 framwork but it seems that it keeps refering to 2.0.

• Transitioning to Branching with TFS

  - by Rob

  Our team is currently using plain old TFS 2005, no branching, shared checkouts etc... I would like to introduce a DEV/MAIN/PROD branching system simillar to the basic flavor in the TFS Guidance document so that we can do some parallel dev, isolation, and firm up review and deployment processes. I have read most of the whitepapers etc. Do you guys have any practical advice, suggested tools, gotchas or reccomendations. Also, we plan to migrate to 2010 once it comes out - not sure if that would affect anything. I appreciate all the suggestions and help I can get as I am a branching neophyte. Thanks in advance.

• How to Grant IIS 7.5 access to a certificate in certificate store?

  - by thames

  In Windows 2003 it was simple to do and one could use the winhttpcertcfg.exe (download) to give "NETWORK SERVICE" account access to a certificate. I'm now using Windows Server 2008 R2 with IIS 7.5 and I am unable to find where and how to set permissions access permissions to a certificate in the certificate store. This Post showed how to do it in Vista and that winhttpcertcfg features were added into the certificates mmc however it doesn't seem to work with imported certificates or doesn't work anymore on Server 2008 R2. So does anyone have any idea on how give IIS 7.5 the correct permissions to read a certificate from the certificate store? And also what account from IIS 7.5 that needs the permission.

• Detect and record a sound with python

  - by Jean-Pierre

  I'm using this program to record a sound in python: import pyaudio import wave import sys chunk = 1024 FORMAT = pyaudio.paInt16 CHANNELS = 1 RATE = 44100 RECORD_SECONDS = 5 WAVE_OUTPUT_FILENAME = "output.wav" p = pyaudio.PyAudio() stream = p.open(format = FORMAT, channels = CHANNELS, rate = RATE, input = True, frames_per_buffer = chunk) print "* recording" all = [] for i in range(0, RATE / chunk * RECORD_SECONDS): data = stream.read(chunk) all.append(data) print "* done recording" stream.close() p.terminate() write data to WAVE file data = ''.join(all) wf = wave.open(WAVE_OUTPUT_FILENAME, 'wb') wf.setnchannels(CHANNELS) wf.setsampwidth(p.get_sample_size(FORMAT)) wf.setframerate(RATE) wf.writeframes(data) wf.close() I want to change the program to start recording when sound is detected by the sound card input. Probably should compare the input sound level in Chunk, but how do this?

• input type text and onKeyDown not working under IE

  - by dygi

  Hi there. I am writing a WWW application, it has to run under IE. I have the problem with the code that runs under FF, but i can't get it running under IE. // JS code function test() { if (window.event.keyCpde == 13) window.location.href.ssign("myPage.php"); } I've tried some similar ways around window.location and location.href, also document.location. I've read that IE has problems with that, so i ask for a solution. The goal is, that page reloads after typing in some text into <input type='text' name='item_code' onKeyDown='test()'> and click enter. So the result is similar to pressing submit type button below the text input. Within IE it reloads the same page and nothing happens. In FF it correctly works.

• Best practices for fixed-width processing in .NET

  - by jmgant

  I'm working a .NET web service that will be processing a text file with a relatively long, multilevel record format. Each record in the file represents a different entity; the record contains multiple sub-types. (The same record format is currently being processed by a COBOL job, if that gives you a better picture of what we're looking at). I've created a class structure (a DATA DIVISION if you will) to hold the input data. My question is, what best practices have you found for processing large, complex fixed-width files in .NET? My general approach will be to read the entire line into a string and then parse the data from the string into the classes I've created. But I'm not sure whether I'll get better results working with the characters in the string as an array, or with the string itself. I guess that's the specific question, string vs. char[], but I would appreciate any other pointers anyone has. Thanks.

• Using sed for introducing newline after each > in a +1 gigabyte large one-line text file

  - by wasatz

  I have a giant text file (about 1,5 gigabyte) with xml data in it. All text in the file is on a single line, and attempting to open it in any text editor (even the ones mentioned in this thread: http://stackoverflow.com/questions/159521/text-editor-to-open-big-giant-huge-large-text-files ) either fails horribly or is totally unusable due to the text editor hanging when attempting to scroll. I was hoping to introduce newlines into the file by using the following sed command sed 's/>/>\n/g' data.xml > data_with_newlines.xml Sadly, this caused sed to give me a segmentation fault. From what I understand, sed reads the file line-by-line which would in this case mean that it attempts to read the entire 1,5 gig file in one line which would most certainly explain the segfault. However, the problem remains. How do I introduce newlines after each in the xml file? Do I have to resort to writing a small program to do this for me by reading the file character-by-character?

• Hardware Lossless Compression for Hard Drives?

  - by GeoffreyF67

  I happened across this article about hardware based hard drive encryption and realized that not only would this give a great way to protect your data but it would also speed up the applications that we use to encrypt that data. This lead me to wonder... Would it be possible to do the same thing for compression so that all of the data is compressed or uncompressed appropriately as it is read and written to the drive? I haven't done any firmware programming in quite some time so I'm not even sure this is technically possible. If it were, however, it could probably give quite a bit more storage space to folks. What are the pros and cons of programming such an approach to be used in the firmware? G-Man

• Where is my SQLite database?

  - by Brian Ramsay

  I have installed SQLite version 3 into a non-standard location on my dreamhost user account. I compiled it and installed it just fine, and it works with $db=new SQLiteDatabase("db.foont"); I can create tables and insert and read data with the SQLiteDatabase object just fine. However, I want to use PDO. My problem is that PDO requires an absolute path to the database specified in the connection. e.g., 'sqlite:/path/to/db.sq3' a) this is dumb - if the other object can figure out where the db is without an absolute path why can't PDO's sqlite driver - but that's not my question. b) where the heck is my database being stored? I can't find it anywhere in my user filesystem, and I'm pretty sure I don't have access to anything else.

• Continuous integration with ClearCase and long-updating snapshot views

  - by Yulia Rogovaya

  Hi, I need to set up a continuous integration system. We use ClearCase version control and only snapshot views due to platform restrictions. I have tried setting up Hudson and Luntbuild. They both show the same behaviour. In a view, we have lots of libraries that are used for build but are strictly read-only. The CI system executes cleartool lshistory and finds a change in the VCS. After that, it executes cleartool setcs, which causes update of the view. This can take about half an hour, which is very undesirable for CI. Why wouldn't it update only the changed elements, which were previously obtained by cleartool lshistory? Is there a CI system that can do this?

• ffmpeg 0.5 flv to wav conversion creates wav files that other programs won't open.

  - by superrebel

  Hi, I am using the following command to convert FLV files to audio files to feed into julian, a speech to text program. cat ./jon2.flv | ffmpeg -i - -vn -acodec pcm_s16le -ar 16000 -ac 1 -f wav - | cat - > jon2.wav The cat's are there for debugging purposes as the final use will be a running program that will pipe FLV into ffmpeg's stdin and the stdout going to julian. The resulting wave files are identified by "file" as: jon3.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 16000 Hz VLC (based on ffmpeg) plays the file, but no other tools will open/see the data. They show empty wav files or won't open/play. For example Sound Booth from CS4. Has anyone else had similar problems? Julian requires wav files 16bit mono at 16000 Hz. Julian does seem to read the file, but doesn't seem to go through the entire file (may be unrelated). Thanks, -rr

• Java Webstart Truststore SSL

  - by Padur

  Hello Experts .. Need some guidance. I have java webstart app and I want it to connect to a server via SSL.just adding a property like:System.setProperty("javax.net.ssl.trustStore","my.keystore");But since a JAWS program is downloaded from server didn't work and don't have a my.keystore on local file system. So decided to distribute the certificate to all clients.I did the following and it worked, but I am sure there are more better solutions that this.I packed it inside a jar and copied to some temp directory on clients machine and read the truststore jks file. Any ideas to make it better? -Padur ========================================

• java runtime 6 with socks v5 proxy - Possible?

  - by rwired

  I have written an application that (amongst other things) runs a local service in windows that acts as a SOCKS v5 proxy for Firefox. I'm in the debugging phase right now and have found certain websites that don't work correctly. For example the Java Applet for Picture Uploading on Facebook.com fails because is is unable to lookup domains. My app overrides a hidden FF config setting network.proxy.socks__remote__dns setting it to true. The whole purpose of the app is to allow access to websites when behind a firewall (e.g. if the user is in China), so this setting is essential to ensure domains are resolved remotely also (and not just HTTP requests). In the JRE6 settings (documented here) there isn't an equivalent setting, and since remote DNS resolution is a feature of SOCKS v5 and not v4 as the documentation seems to imply I'm worried that it's just not possible. How can I programmatically make sure the JRE uses a SOCKS v5 proxy for all requests (including DNS)? UPDATE: Steps to reproduce this problem: Make sure you are behind a firewall that blocks (or redirects) internet access including DNS Install PuTTY and add a dynamic SSH tunnel on some port number of your choice (e.g. 9870). Then login to a remote server that has full access to the internet Launch Firefox and you will not be able to browse the web In FF network settings set the SOCKS v5 proxy to localhost:9870 In FF go to about:config, change network.proxy.socks__remote__dns to true You will now be able to browse the web. Go to facebook.com, login, go to your profile and attempt to use the picture uploader java applet to add some pictures It will fail with a series of class not found errors looking similar to: load: class com.facebook.facebookphotouploader5.FacebookPhotoUploader5.class not found. I believe this is failing because the JRE is unable to resolve the domain that the class resides on. I'm basing this belief on the fact that the documentation (http://java.sun.com/javase/6/docs/technotes/guides/deployment/deployment-guide/properties.html) talks only about SOCKS v4 (which as far as I know does not support remote DNS). My deployment.properties file is located in %APPDATA%\Sun\Java\Deployment. I can confirm that modifications I make in the Java Control Panel get written into that file. If instead of "Use browser setting" the network settings for Java I override and attempt to use the SOCKS proxy settings manually, I still have the issue. There does not seem to be an easy way to force the JRE to do DNS remotely through the Proxy. UPDATE 2: Without the SOCKS proxy, from my local client www.facebook.com resolves to 203.161.230.171 upload.facebook.com resolves to 64.33.88.161 Neither host is reachable (because of the firewall) If I login to the remote server, I get: www.facebook.com 69.63.187.17 upload.facebook.com 69.63.178.32 Both these IPs change after a few minutes, as it seems Facebook uses round-robin DNS and other load-balancing. With the Proxy settings set in Firefox, I can navigate to www.facebook.com without any difficulty (since DNS is being resolved remotely on the Proxy). Whey I go to the page with the Java applet it fails with the stacktrace messages I've already reported. However if I edit Windows\System32\drivers\etc\hosts, adding the correct IP for upload.facebook.com I can get the applet to load and work correctly (restart of FF is sometimes necessary). This evidence seems to support my theory that the Java Runtime is not resolving DNS on the Proxy, but instead just routing traffic though it. My application is for mass-deployment, and needs to work with java applets on other sites (not just facebook). I really need a work-around for this problem. UPDATE 3 Stacktrace dump a requested by ZZ Coder: load: class com.facebook.facebookphotouploader5.FacebookPhotoUploader5.class not found. java.lang.ClassNotFoundException: com.facebook.facebookphotouploader5.FacebookPhotoUploader5.class at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.plugin2.applet.Plugin2ClassLoader.loadCode(Unknown Source) at sun.plugin2.applet.Plugin2Manager.createApplet(Unknown Source) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: java.net.SocketException: Connection reset at java.net.SocketInputStream.read(Unknown Source) at java.io.BufferedInputStream.fill(Unknown Source) at java.io.BufferedInputStream.read1(Unknown Source) at java.io.BufferedInputStream.read(Unknown Source) at sun.net.www.http.HttpClient.parseHTTPHeader(Unknown Source) at sun.net.www.http.HttpClient.parseHTTP(Unknown Source) at sun.net.www.http.HttpClient.parseHTTP(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at java.net.HttpURLConnection.getResponseCode(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader.getBytes(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader.access$000(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) ... 7 more Exception: java.lang.ClassNotFoundException: com.facebook.facebookphotouploader5.FacebookPhotoUploader5.class Dumping class loader cache...

• Trouble connecting to vsftpd on ubuntu server

  I have installed Ubuntu Server 10.10 and I am using it to host a domain that I have. I am trying to set up FTP for the server, but I am running into some problems. I have successfully installed vsFTPd and I have opened up ports 20, 21 on my firewall. In my vsFTPd configuration, I have enabled SSL. Every time I try to connect to my server via FTP, I receive a "Connection Refused" error.

• VI/VIM file handling

  - by Abhimanyu

  Nowa days I'm working with the Vi editor with the positive approach that you can do most things using it - unlike other editors. I came across one problem: Let's assume I have open a folder with vi <folder name> so it opens the folder in Vi and lists the files in that folder. I select a file and read the content, then I want to go back to the previous view which has filenames listed so it is easy to choose another file. But don't know how to achieve this. I'm hoping some method should be there to achieve this.

• How do I reduce number of redundant requests with mod_perl properly?

  - by rassie

  In a fairly big legacy project, I've refactored several hairy modules into Moose classes. Each of these modules requires database access to (lazy) fetch its attributes. Since those objects are used pretty heavily, I want to reduce the number of redundant requests, for example for unchanged data. Now, how do I do that properly? I've got several alternatives: Implement caching in my Moose classes via a role to store them in memcached with expiration of 5-10 minutes (probably not too difficult, but tricky with lazy attributes) update: KiokuDB could probably help here, have to read up about attributes Migrate to DBIx::Class (needs to be done anyway) and implement caching on this level (DBIC will probably take most of the pain away just by itself) Somehow make my objects persist inside the mod_perl process (no clue how to do this :() How would you do this and what do you consider a sane way? Is caching data preferred on object or the ORM level?

  Hello, I want to build an app that send SMS to people. However, I want my users to know that the SMS comes from the app and nothing else so they can't fake it. Is there a way to guarantee that the sender ID is unique to my app? It seems that sending a SMS by phone is with a unique SENDER ID for each phone number. But, from what I read, I don't think it is the case when sending a SMS through a web gateway. Is this correct? I am not an expert in mobile phone security. Of course, I am willing to pay the price for a unique sender id, if such thing is possible. Regards, Pascal
