  • Does ASL License complies with MS-Pl license?

    - by John Simons
    I would like to redistribute a compiled version of Yahoo! UI Library: YUI Compressor for .Net (http://yuicompressor.codeplex.com), that according to the web site is licensed under MS-Pl (http://yuicompressor.codeplex.com/license). The project I work in is release under the terms of Apache Software Foundation License 2.0. According to the MS-Pl license "If you distribute any portion of the software in compiled or object code form, you may only do so under a license that complies with this license." , the term complies is not very clear! Does ASL License complies with MS-Pl license?

  • Get last n lines of a file with Python, similar to tail

    - by Armin Ronacher
    I'm writing a log file viewer for a web application and for that I want to paginate through the lines of the log file. The items in the file are line based with the newest item on the bottom. So I need a tail() method that can read n lines from the bottom and supports an offset. What I came up with looks like this: def tail(f, n, offset=0): """Reads a n lines from f with an offset of offset lines.""" avg_line_length = 74 to_read = n + offset while 1: try: f.seek(-(avg_line_length * to_read), 2) except IOError: # woops. apparently file is smaller than what we want # to step back, go to the beginning instead f.seek(0) pos = f.tell() lines = f.read().splitlines() if len(lines) >= to_read or pos == 0: return lines[-to_read:offset and -offset or None] avg_line_length *= 1.3 Is this a reasonable approach? What is the recommended way to tail log files with offsets?

  • Having an issue with overwriting an element of a file correctly (numeric)

    - by IngeniousHax
    This is an ATM style program, but currently it doesn't do exactly what I need it to do... I need to get the current balance, and when money is transferred from either checking or savings, it should add it to checking and subtract it from savings. which is does, but not correctly... Input example -=[ Funds Transfer ]=- -=[ Savings to Checking ]=- Account Name: nomadic Amount to transfer: $400 New Balance in Checking: $900 // original was 500 New Balance in Savings: $7.7068e+012 // this should now be 1100...

  • Fork in Perl not working inside a while loop reading from file

    - by Sag
    Hi, I'm running a while loop reading each line in a file, and then fork processes with the data of the line to a child. After N lines I want to wait for the child processes to end and continue with the next N lines, etc. It looks something like this: while ($w=<INP>) { # ignore file header if ($w=~m/^\D/) { next;} # get data from line chomp $w; @ws = split(/\s/,$w); $m = int($ws[0]); $d = int($ws[1]); $h = int($ws[2]); # only for some days in the year if (($m==3)and($d==15) or ($m==4)and($d==21) or ($m==7)and($d==18)) { die "could not fork" unless defined (my $pid = fork); unless ($pid) { some instructions here using $m, $d, $h ... } push @qpid,$pid; # when all processors are busy, wait for child processes if ($#qpid==($procs-1)) { for my $pid (@qpid) { waitpid $pid, 0; } reset 'q'; } } } close INP; This is not working. After the first round of processes I get some PID equal to 0, the @qpid array gets mixed up, and the file starts to get read at (apparently) random places, jumping back and forth. The end result is that most lines in the file get read two or three times. Any ideas? Thanks a lot in advance, S.

  • django authentication .htaccess static

    - by Uszy Wieloryba
    In my app users can upload files for other users. To make the uploaded files accesible only for the addresse I need some kind of static files authentication system. My idea, is to create the apache hosted directory for each user and to limit access to this derectory using .htaccess. This means that each time new django user is created, I need to create a directory and the appropriate .htaccess file in it. I know I should do it using post_save signals on User model but I don't know how to create the .htaccess in the user's directory from python level. Can you help me with that? Or perhaps you have better solution to my problem?

  • How to create a Java String from the contents of a file

    - by Oscar Reyes
    I've been using this idiom for some time now. And it seems to be the most wide spread at least in the sites I've visited. Does anyone have a better/different way to read a file into a string in Java. Thanks private String readFile( String file ) throws IOException { BufferedReader reader = new BufferedReader( new FileReader (file)); String line = null; StringBuilder stringBuilder = new StringBuilder(); String ls = System.getProperty("line.separator"); while( ( line = reader.readLine() ) != null ) { stringBuilder.append( line ); stringBuilder.append( ls ); } return stringBuilder.toString(); }

  • Persist changes in C

    - by Mohit Deshpande
    I am developing a database-like application that stores a a structure containing: struct Dictionary { char *key; char *value; struct Dictionary *next; }; As you can see, I am using a linked list to store information. But the problem begins when the user exits out of the program. I want the information to be stored somewhere. So I was thinking of storing the linked list in a permanent or temporary file using fopen, then, when the user starts the program, retrieve the linked list. Here is the method that prints the linked list to the console: void PrintList() { int count = 0; struct Dictionary *current; current = head; if (current == NULL) { printf("\nThe list is empty!"); return; } printf(" Key \t Value\n"); printf(" ======== \t ========\n"); while (current != NULL) { count++; printf("%d. %s \t %s\n", count, current->key, current->value); current = current->next; } } So I am thinking of modifying this method to print the information through fprintf instead of printf and then the program would just get the infomation from the file. Could someone help me on how I can read and write to this file? What kind of file should it be, temporary or regular? How should I format the file (like I was thinking of just having the key first, then the value, then a newline character)?

  • XAMPP is caching .html files running as PHP

    - by Lee
    I have XAMPP (latest version) installed on my Mac OS 10.6.3 I've added the following to .htaccess because I want .html to be interpreted as PHP. AddType application/x-httpd-php .php .html The problem is that the default XAMPP config seems to be caching .html files as static... so even though the PHP statements inside are being called (for example, 'echo time()' in index.html displays the dynamic output)... the actual file is being cached. When I make changes to a .html file, I've having to restart Apache for it to load the newest changes. Looking at httpd.conf, it looks like it's loading the following cache mods.. LoadModule file_cache_module modules/mod_file_cache.so LoadModule cache_module modules/mod_cache.so LoadModule disk_cache_module modules/mod_disk_cache.so LoadModule mem_cache_module modules/mod_mem_cache.so Any idea how to implement a system whereby it checks the timestamp of the file, before loading it from cache? Thanks!

  • May the FileInputStream.available foolish me?

    - by Tom Brito
    This FileInputStream.available() javadoc says: Returns an estimate of the number of remaining bytes that can be read (or skipped over) from this input stream without blocking by the next invocation of a method for this input stream. The next invocation might be the same thread or another thread. A single read or skip of this many bytes will not block, but may read or skip fewer bytes. In some cases, a non-blocking read (or skip) may appear to be blocked when it is merely slow, for example when reading large files over slow networks. I'm not sure if in this check: if (new FileInputStream(xmlFile).available() == 0) can I rely that empty files will always return zero?

  • loading data from file into 2d array

    - by Chris
    I am just starting with perl and would like some help with arrays please. I am reading lines from a data file and splitting the line into fields: open (INFILE, $infile); do { my $linedata = <INFILE>; my @data= split ',',$linedata; .... } until eof; I then want to store the individual field values (in @data) in and array so that the array looks like the input data file ie, the first "row" of the array contains the first line of data from INFILE etc. Each line of data from the infile contains 4 values, x,y,z and w and once the data are all in the array, I have to pass the array into another program which reads the x,y,z,w and displays the w value on a screen at the point determined by the x,y,z value. I can not pas the data to the other program on a row-by-row basis as the program expects the data to in a 2d matrtix format. Any help greatly appreciated. Chris

    hi, I intend on writing a small download manager in C++ that supports resuming (and multiple connections per download). From the info I gathered so far, when sending the http request I need to add a header field with a key of "Range" and the value "bytes=startoff-endoff". Then the server returns a http response with the data between those offsets. So roughly what I have in mind is to split the file to the number of allowed connections per file and send a http request per splitted part with the appropriate "Range". So if I have a 4mb file and 4 allowed connections, I'd split the file to 4 and have 4 http requests going, each with the appropriate "Range" field. Implementing the resume feature would involve remembering which offsets are already downloaded and simply not request those. Is this the right way to do this? What if the web server doesn't support resuming? (my guess is it will ignore the "Range" and just send the entire file) When sending the http requests, should I specify in the range the entire splitted size? Or maybe ask smaller pieces, say 1024k per request? When reading the data, should I write it immediately to the file or do some kind of buffering? I guess it could be wasteful to write small chunks. Should I use a memory mapped file? If I remember correctly, it's recommended for frequent reads rather than writes (I could be wrong). Is it memory wise? What if I have several downloads simultaneously? If I'm not using a memory mapped file, should I open the file per allowed connection? Or when needing to write to the file simply seek? (if I did use a memory mapped file this would be really easy, since I could simply have several pointers). Note: I'll probably be using Qt, but this is a general question so I left code out of it.

  • Can't get Xdebug to work on Windows 7

    - by Derek
    I installed the latest XAMPP package which includes PHP 5.3.0. I am trying to enable Xdebug, but it just won't work. Here's what I changed in the php.ini shipped with XAMPP: ; uncommented zend_extension = "X:\xampp\php\ext\php_xdebug.dll" ; added the following lines: xdebug.remote_enable=true xdebug.remote_host=localhost xdebug.remote_port=9000 xdebug.remote_handler=dbgp Apache starts fine, but when I open http://localhost/ in my browser, I get the following error If I click the Close the program button, the error message will reappear in a second as if it was in an infinite loop. I'd greatly appreciate any help in getting this to work. I am running a fresh install of Windows 7 Ultimate 64-bit.

  • What should be the ideal number of parallel java threads for copying a large set of files from a qua

    - by ukgenie
    What should be the ideal number of parallel java threads for copying a large set of files from a quad core linux box to an external shared folder? I can see that with a single thread it is taking a hell lot of time to move the files one by one. Multiple threads is improving the copy performance, but I don't know what should be the exact number of threads. I am using Java executor service to create the thread pool.

  • Dynamically setting a log4net property using common.logging

    - by Kyle LeNeau
    Does anyone know if there is an equivalent in Common.Logging (for .Net) to set properties for the log4net factory adapter? I have had great success when just using log4net by doing: <appender name="FileAppender" type="log4net.Appender.RollingFileAppender"> <file type="log4net.Util.PatternString" value="logs\Log_%property{BrokerID}.txt"/> <appendToFile value="false"/> <rollingStyle value="Size"/> <maxSizeRollBackups value="-1"/> <maximumFileSize value="50GB"/> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date %-5level %logger - %message%newline"/> </layout> </appender> and setting the property like:log4net.GlobalContext.Properties["BrokerID"] = 10 The file I end up with the looks like this: Log_(null).txt when using the common.logging to wire up log4net on the fly.

  • How to walk through two files simultaneously in Perl?

    - by Alex Reynolds
    I have two text files that contain columnar data of the variety position-value. Here is an example of the first file (file A): 100 1 101 1 102 0 103 2 104 1 ... Here is an example of the second file (B): 20 0 21 0 ... 100 2 101 1 192 3 193 1 ... Instead of reading one of the two files into a hash table, which is prohibitive due to memory constraints, what I would like to do is walk through two files simultaneously, in a stepwise fashion. What this means is that I would like to stream through lines of either A or B and compare position values. If the two positions are equal, then I perform a calculation on the values associated with that position. Otherwise, if the positions are not equal, I move through lines of file A or file B until the positions are equal (when I again perform my calculation) or I reach EOF of both files. Is there a way to do this in Perl?

  • Reading Resource Files from my own APK in Android Native Environment

    - by Kyle
    I'm porting to Android. My existing project has a ton of resource files that I'm porting into my Android project. I have them all in /res/raw/, and I would like to access those resources in my native library with functions such as fopen() and such. Can this be done, or do I have to go through JNI for this as well? I would really prefer not to, for ease of porting and possible speed and memory reasons.

  • strange messages in log file @^@^@^@^@^@^@^@^@^@^@^@^@^@^@^....

    - by celalo
    Hello, I have a application server for network operations written with JAVA based on Apache Mina. Recently I encounter a strange behavior in my log files. I noticed that the log file is full of @^@^@^@^@^@^@^@^@^@^@^@^.... characters. I mean those unexpected characters are vast amount of as such the log file gets hundreds of GB in a couple of hours! I have no clue about this problem and it is almost impossible to google it. What could be the reason? Are those set of characters any familiar to anybody? I can give more details about the application if needed. Thanks in advance.

  • File size and mime-type before upload

    - by Marcos Placona
    Hi, I've scavenged on every single topic on this forum to try and find an answer before I posted this. Most people say you should simply use SWFUpload, some others mention Activex, and it keeps going. I know this is do-able, as Google does it with gMail when you try to upload a file that's bigger than 25mb, or executable. My question is, how can I determine the file size and mime-type before the file actually hits my server. I primarily thought it was an impossible task, but Google proves me wrong. Could anyone give me a definitive answer on how to accomplish such task? Thanks

  • Zend Framework REST service HTTP status code problem

    I'm trying to create a REST service in zend framework. I'm using zend server.

The only way I can think of to remove the appended error document is to add the following in my httpd.conf file: ErrorDocument 201 " " But what's the "corrent" way of doing this?

  • How can I redirect the output of Perl's system() to a filehandle?

    - by syker
    With the open command in Perl, you can use a filehandle. However I have trouble getting back the exit code with the open command in Perl. With the system command in Perl, I can get back the exit code of the program I'm running. However I want to just redirect the STDOUT to some filehandle (no stderr). My stdout is going to be a line-by-line output of key-value pairs that I want to insert into a mao in perl. That is why I want to redirect only my stdout from my Java program in perl. Is that possible? Note: If I get errors, the errors get printed to stderr. One possibility is to check if anything gets printed to stderr so that I can quite the Perl script.

  • htaccess rewrite issue while testing on localhost

    - by James Doc
    I'm running OSX (10.6) with Apache with .htaccess enabled. In the htaccess file I have the code: Options +FollowSymlinks RewriteEngine on RewriteRule ^page/([A-Z0-9._%+-]+) index.php?page=$1 [NC] This runs perfectly on my external server and redirects nicely to index.php?page=whatever However when testing locally from localhost/~james/In%20Progress/Vila%20Maninga/page/whatever I get redirected to localhost/~james/Users/James/Sites/In%20Progress/Vila%20Maninga/index.php?page=whatever. For some reason 'Users/James/Sites/' is being added. Does anyone why this is happening and how to prevent it? Many thanks, James

  • PHP is unable to open a file for writing - but it does exist

    - by asdasdas
    I am trying to write to a file. I do a file_exists check on it before i do fopen and it comes up true: the file does exist. However, the file fails this code and gives me the error every time: $handle = fopen($filename, 'w'); if($handle) { flock($handle, LOCK_EX); fwrite($handle, $contents); } else { echo 'ERROR: Unable to open the file for writing.',PHP_EOL; exit(); } flock($handle, LOCK_UN); fclose($handle); Is there a way I can get more specific error details as to why this file does not let me open it for writing? I know that the filename is legit, but for some reason it just wont let me write to it. I do have write permissions, I was able to write and write over another file.
