• How to get the real, actual duration of an MP3 file (VBR or CBR) server-side

  - by Cummander Checkov

  I used to calculate the duration of MP3 files server-side using ffmpeg - which seemed to work fine. Today i discovered that some of the calculations were wrong. Somehow, for some reason, ffmpeg will miscalculate the duration and it seems to happen with variable bit rate mp3 files only. When testing this locally, i noticed that ffmpeg printed two extra lines in green. Command used: ffmpeg -i song_9747c077aef8.mp3 ffmpeg says: [mp3 @ 0x102052600] max_analyze_duration 5000000 reached at 5015510 [mp3 @ 0x102052600] Estimating duration from bitrate, this may be inaccurate After a nice, warm google session, i found some posts on this, but no solution was found. I then tried to increase the maximum duration: ffmpeg -analyzeduration 999999999 -i song_9747c077aef8.mp3 After this, ffmpeg returned only the second line: [mp3 @ 0x102052600] Estimating duration from bitrate, this may be inaccurate But in either case, the calculated duration was just plain wrong. Comparing it to VLC i noticed that here the duration is correct. After more research i stumbled over mp3info - which i installed and used. mp3info -p "%S" song_9747c077aef8.mp3 mp3info then returned the CORRECT duration, but only as an integer, which i cannot use as i need a more accurate number here. The reason for this was explained in a comment below, by user blahdiblah - mp3info is simply pulling ID3 info from the file and not actually performing any calculations. I also tried using mplayer to retrieve the duration, but just as ffmpeg, mplayer is returning the wrong value. Now i ran out of options. If somebody knows how to get around this, any hints, tips, guides or corrections are welcome! Thank You!

• Servlet File Upload Memory Consumption

  - by Scott

  Hi, I'm using a servlet to do a multi fileupload (using apache commons fileupload to help). A portion of my code is posted below. My problem is that if I upload several files at once, the memory consumption of the app server jumps rather drastically. This is probably OK if it were only until the file upload is finished, but the app server seems to hang on to the memory and never return it to the OS. I'm worried that when I put this into production I'll end up getting an out of memory exception on the server. Any ideas on why this is happening? I'm thinking the server may have started a session and will give the memory back after it expires, but I'm not 100% positive. if(ServletFileUpload.isMultipartContent(request)) { ServletFileUpload upload = new ServletFileUpload(); FileItemIterator iter = upload.getItemIterator(request); while(iter.hasNext()) { FileItemStream license = iter.next(); if(license.getFieldName().equals("upload_button") || license.getName().equals("")) continue; //DataInputStream stream = new DataInputStream(license.openStream()); InputStream stream = license.openStream(); ArrayList<Integer> byteArray = new ArrayList<Integer>(); int tempByte; do { tempByte = stream.read(); byteArray.add(tempByte); }while(tempByte != -1); stream.close(); byteArray.remove(byteArray.size()-1); byte[] bytes = new byte[byteArray.size()]; int i = 0; for(Integer tByte : byteArray) { bytes[i++] = tByte.byteValue(); } Thanks in advanced!!

• complete nub.. iostream file not found

  - by user1742389

  folks I am almost completely new to programming so please bear with me. I am using the first example from lydia.com c++ videos and failing. I am using Xcode 4.5.1 with a c++ command line project instead of eclipse and I am getting an error on compile of iostream file not found. the code is simple and I will include exactly what I have at the end of this message. I thought that iostream was a standard header that came with all even remotely recent versions of c++ compilers and am shocked to get this error and I cannot find any way to fix this. please tell me whats going on. #include <iostream> #include <stdio.h> #include <sstream> #include <vector> int main(int argc, char ** argv) { stringstream version; version << "GCC Version"; _GNUC_<<"."<<_GNUC_MINOR_<<"."<<_GNUC_PATCHLEVEL_<<_"\nVersion String: " <<_VERSION_; cout <<version.string() endl; vector<string> v={"one","two","three"}; for ( s : v ) { cout << s <<endl; } // insert code here... printf("Hello, World!\n"); return 0; } Thanks.

• Evaluating creation of GUI via file vs coding

  - by nevets1219

  I'm working on a utility that will be used to test the project I'm currently working on. What the utility will do is allow user to provide various inputs and it will sends out requests and provide the response as output. However, at this point the exact format (which input is required and what is optional) has yet to be fleshed out. In addition, coding in Swing is somewhat repetitive since the overall work is simple though this should be the safest route to go as I have more or less full control and every component can be tweaked as I want. I'm considering using a configuration file that's in XML to describe the GUI (at least one part of it) and then coding the event handling part (in addition to validation, etc). The GUI itself shouldn't be too complicated. For each type of request to make there's a tab for the request and within each tab are various inputs. There seems to be quite a few questions about this already but I'm not asking for a 3rd party library to do this. I'm looking to do this myself, since I don't think it'll be too overly complicated (hopefully). My main consideration for using this is re-usability (later on, for other projects) and for simplifying the GUI work. My question is: are there other pros/cons that I'm overlooking? Is it worth the (unknown) time to do this? I've built GUI in VB.NET and with Flex3 before.

• Client-side user custom CSS single file for overriding multiple domains

  - by Cawas

  This is for using in Safari, though it could probably be used on Firefox as well. In Chrome you have to add a plugin anyway (which generally allow for custom CSS per domain), and Opera already allows this to be done without needing any CSS. But while it's for customizing on the client-side, it's also a pure CSS question. So I'm using no plugins here. So, again, I got a custom CSS code (easily) working for all domains. Now I want to get specify CSS code for each domain. All with just 1 CSS file that's being loaded by Safari. Over the web and googling, I've found two ways to supposedly do this, but none actually worked. They're both documented on userstyles.com: @-moz-document domain("your-domain.com") { }. This would be perfect, since I can have several tags like that and just choose which style will be loaded for which domain. It just doesn't work. @namespace is quite confusing and I've tried every variation I could think of. None worked.

• Could not laod file or assembly ‘System.Web.Silverlight’

  - by Adam Berent

  I really need some help with this as I have been trying to fix this for months and I can't figure it out. I run an online chess site written in Silverlight 3.0 The architecture is Silverlight Client connecting to a WCF service that reads and writes data to a SQL Server database. It is hosted on Godaddy, Once every so often I get the following error: Could not laod file or assembly ‘System.Web.Silverlight’ or one of its dependencies. The system cannot find the path specified. If I leave it alone it will fix itself after a few hours, however usually I just make a new publish of my application and it goes away. Also all the pages in the solution get this message not just the Silverlight application. So I have an aspx page with top ranks that does not use Silverlight but is in the same solution it also gets the same error. Its almost like the whole site dies. This does not seem like a huge issue but it makes going on vacation hard since my site can go down at any time I am away. Also this seems to happen the most when I am sleeping so I often don't get to fixing it until I have already lost hours of potential logins. If you have had the same issue please, please help!

• LNK1104: cannot open file 'kernel32.lib'

  - by Geoff

  I Had VS2010 installed but found that intellisense wasn't working. I looked on the web and found that I wasn't the only one who had that issue. So, I installed VS2008 and everything was fine. Then I decided to clean up my computer and removed VS2010 and immediately started getting this error on my programs (new and old). Even a simple test program that has one cout command. I tried repairing VS2008 and that didn't work so I tried to uninstall and then reinstall and still I am getting the same problem. I have looked online for this issue and though I have found a lot of other people are experiencing this issue it is not the same. They are having problems with other external references, not the ones that should automatically be included like kernel32 and lib32 etc. I also tried the solution that worked for some people with their other references and I included the path (with and without quotes) to my kernel32 directory but still I get the same problem, or in some instances I will get LNK1104: cannot open file 'C:\WINDOWS\system32.obj' with and without quotes in the linker config. Can anyone please help?

• Can't use method from class in other file

  I am not able to use one of my methods that i implemented in my tableviewcell file in my tableview controller implementation. I tried searching the web and xcode help with no luck. My codes looks like this: TableViewController.h: #import TableViewCell.h @interface TableViewController : UITableViewController @property (nonatomic, strong) IBOutlet UIBarButtonItem *A1Buy; @property (nonatomic, getter = isUserInteractionEnabled) BOOL userInteractionEnabled; - (IBAction)A1Buy:(UIBarButtonItem *)sender; TableViewController.m: @implementation A1ViewController @synthesize A1Buy = _A1Buy; @synthesize userInteractionEnabled; - (IBAction)A1Buy:(UIBarButtonItem *)sender { [TableViewCell Enable]; //this is where it gives an error } TableViewCell.h: @interface TableViewCell : UITableViewCell { BOOL Enable; BOOL Disable; } @property (nonatomic, getter = isUserInteractionEnabled) BOOL userInteractionEnabled; TableViewCell.m: @implementation TableViewCell; @synthesize userInteractionEnabled; - (BOOL) Enable { return userInteractionEnabled = YES; } - (BOOL) Disable { return userInteractionEnabled = NO; } As you can see i am trying to enable user interaction with a button, but Xcode only gives me errors like "class does not have this method" and stuff like that. All files are importet correctly so thats not why. Would appreciate any help. Thanks!

• Trying to move files with specific file names from root directory to a subfolder

  - by Justin Reagan

  Hi I'm still pretty new to powershell so I apologize if I ask something that extremely basic. I have a root directory on a tftp server that pulls down config files from routers and other equipment every night. The files are like this IPaddress_YYYYMMDD_TA5000. There is a limitation in the equipment where the files can't be set to move into the root directory on their own. What I want to do is make a powershell script that will only move the files with the TA5000 part in the filename to the sub directory and only keep the 5 most recent files. I looked but I couldn't seem to find what I would need to do to parse the file for that specific string. I already have the portion of the script to delete the files based on age that was simple. Any help on getting started would be appreciated. Edit: I forgot to post the code I was trying. Move-Item c:\tftptransferfiles c:\tftptransferfiles\sca | Where-Object {_.name -like "*TA5000*"} I keep getting a error saying that the item at C:\tftptransferfiles is in use.

• Parsing a Multi-Index Excel File in Pandas

  - by rhaskett

  I have a time series excel file with a tri-level column MultiIndex that I would like to successfully parse if possible. There are some results on how to do this for an index on stack overflow but not the columns and the parse function has a header that does not seem to take a list of rows. The ExcelFile looks like is like the following: Column A is all the time series dates starting on A4 Column B has top_level1 (B1) mid_level1 (B2) low_level1 (B3) data (B4-B100+) Column C has null (C1) null (C2) low_level2 (C3) data (C4-C100+) Column D has null (D1) mid_level2 (D2) low_level1 (D3) data (D4-D100+) Column E has null (E1) null (E2) low_level2 (E3) data (E4-E100+) ... So there are two low_level values many mid_level values and a few top_level values but the trick is the top and mid level values are null and are assumed to be the values to the left. So, for instance all the columns above would have top_level1 as the top multi-index value. My best idea so far is to use transpose, but the it fills Unnamed: # everywhere and doesn't seem to work. In Pandas 0.13 read_csv seems to have a header parameter that can take a list, but this doesn't seem to work with parse.

Is there any way to overcome this problem?

• Need help with jquery json data transfer from php file

  - by Scarface

  Hey guys I am trying to return the latest 10 results of a query from a php file, through json format, to a jquery getjson function that prints results. I am getting weird problems though. For example I am only getting 8 entries returned, and some are disordered, and sometimes nothing is returned. I am not really sure what I am doing wrong, so if anyone has any ideas I would really appreciate it. This is my query ($res) SELECT time, user, message FROM comments WHERE topic_id='$topic_id' ORDER BY time DESC LIMIT 10 This is the processing of the results while($row = mysql_fetch_array($res)){ $message=$row['message']; $user=$row['user']; if($row['message'] AND $row['time'] > $_GET['time']) $data[] = $row; } $out = json_encode($data); print $out; And this is the retrieval where prepare is just a function that returns information into a div $.getJSON(files+"processing.php?action=load&time="+0+"&topic_id="+topic_id+"&t=" + (new Date()), function(json) { if(json.length) { for(i=0; i < 10; i++) { $('#comment-list').prepend(prepare(json[i])); $('#list-' + count).fadeIn(1500); } } }); function prepare(response) { count++; var string = '<li class="comment-list" id="list-'+count+'">' //organize info into a div +'</li>'; return string; }

• grep from a log file to get count

  - by subodh1989

  I have to get certain count from files. The grep statement i am using is like this : counter_pstn=0 completed_count_pstn=0 rec=0 for rec in `(grep "merged" update_completed*.log | awk '{print $1}' | sed 's/ //g' | cut -d':' -f2)` do if [ $counter_pstn -eq 0 ] then completed_count_pstn=$rec else completed_count_pstn=$(($completed_count_pstn+$rec)) fi counter_pstn=$(($counter_pstn+1)) done echo "Completed Orders PSTN Primary " $completed_count_pstn But the log file contains data in this format : 2500 rows merged. 2500 rows merged. 2500 rows merged. 2500 rows merged.2500 rows merged. 2500 rows merged. 2500 rows merged. As a result , it is missing out the count of one merge(eg on line 4 of output).How do i modify the grep or use another function to get the count. NOTE that the 2500 number maybe for different logs. So we have to use "rows merged" pattern to get the count. i have tried -o ,-w grep options,but it is not working. Expected output from above data: 17500 Actual output showing : 15000

• c# counting identical strings from text file

  I have a foreach statement where I go through several lines from a text file, where I have trimmed down and sorted out the lines I need. What I want to do is count up on how many times an identical string is present. How do I do this? Here is my code. It's the second if statement where I am stuck: foreach (string line in lines.Where(l => l.Length >= 5)) { string a = line.Remove(0, 11); if ((a.Contains(mobName) && a.Contains("dies"))) { mobDeathCount++; } if (a.Contains(mobName) && a.Contains("drops")) { string lastpart = a.Substring(a.LastIndexOf("drops")); string modifiedLastpart = lastpart.Remove(0, 6); } Heres what some of the lines look like: a bag of coins a siog brandy a bag of coins a bag of coins the Cath Shield a tattered scroll So what im trying to do is counting up there are 3 lines with bag of coins. But i need to make it so that it can be everything, theres a drop lists thats huge. So cant add all of em, would take too long

• Why does my name resolution hit the DNS even with a hosts file entry?

  - by Volomike

  I'm running Ubuntu 10.04.2 LTS Desktop. Being a web developer, naturally I created a "me.com" in my /etc/hosts file. Unfortunately, my name resolution is going out to the DNS before first checking my local hosts entry and I can't figure out why. The end result is that if my /etc/resolv.conf contains "nameserver 127.0.0.1" in there first, then I get a response back in my web browser from me.com (local) within less than a second. But if I don't have that entry, then my response takes sometimes as much as 5 seconds if my ISP is a little slow. The problem was so troublesome that I actually had to file a question here (and someone resolved it) for how to automatically insert that entry into /etc/resolv.conf. But one of the users (@shellaholic) here highly recommended (and commented back and forth with me about it) that I should file this question. Do you know why my workstation's name resolution has to hit the DNS server first before hitting my /etc/hosts file entry? For now, I'm using the resolv.conf trick (see link above).

  I'm running a Lucid Netbook Remix on my Dell Inspiron 600m and I was not able to connect to the wireless network at the Hacker Dojo in Mountain View yesterday. There were plenty of other people on the network - MS, Mac, and Linux boxes - but my laptop would never get an ip address. I can connect to my home network, which is open, and I've never had a problem connecting at the coffee shop, which uses WPA. The Hacker Dojo is running WPA and we checked the password a number of times but got no love. Any ideas would be greatly appreciated.

• Is there a command-line utility app which can find a specific block of lines in a text file, and replace it?

  - by fred.bear

  UPDATE (see end of question) The text "search and replace" utility programs I've seen, seem to only search on a line-by-line basis... Is there a command-line tool which can locate one block of lines (in a text file), and replace it with another block of lines.? For example: Does the test file file contain this exact group of lines: 'Twas brillig, and the slithy toves Did gyre and gimble in the wabe: All mimsy were the borogoves, And the mome raths outgrabe. 'Beware the Jabberwock, my son! The jaws that bite, the claws that catch! Beware the Jubjub bird, and shun The frumious Bandersnatch!' I want this, so that I can replace multiple lines of text in a file and know I'm not overwriting the wrong lines. I would never replace "The Jabberwocky" (Lewis Carroll), but it makes a novel example :) UPDATE: ..(sub-update) My following comment about reasons when not use sed are only in the context of; don't push any tool too far beyond its design intent (I use sed quite often, and consider it to be invaluable.) I just now found an interesting web page about sed and when not to use it. So, because of all the sed answers, I"ll post the link.. it is part of the sed FAQ on sourceforge Also, I'm pretty sure there is some way diff can do the job of locating the block of text (once it's located, the replacement is quite straight foward; using head and tail) ... 'diff' dumps all the necessary data, but I haven't yet worked out how to filter it , ... (I'm still working on it)

• How to Extract the images from the doc file without Having Microsoft office ?

We need to try to extract them in Microsoft word which come with Windows 7 (not Microsoft office word). Looking to this article http://www.techrepublic.com/blog/itdojo/save-images-in-microsoft-word-documents-as-separate-files/135 This article is only useful when you have Microsoft word installed. Now if I don’t have Microsoft office then what ? No problem, here is a trick. when you open the doc file in Word  then select the image and right click on image and choose cut. open the Microsoft paint. paste them here. Without clicking anywhere click on crop icon on toolbar.   Now you got your image in the same size as you have in word file. Don’t worry about Image format. Microsoft paint have support for save them in PNG format.
