• Why is ext3 so slow to delete large files?

  - by Janis Peisenieks

  I have a server, which makes an incremental backup of a system every night. Now on saturdays, there is a full backup. But after the full backup has finished, a script kicks in, that deletes the incrementals. Now, the script sometimes breaks, and it is because the incrementals are each about 10GB files, and sometimes takes too long for the script. Now could someone explain to me, or point me in the direction of a resource, that explains why ext3 is so slow to delete files, when compared to, lets say, NTFS? I know theses are 2 completely different file systems, but I'm really interested why is there such a big difference in deletion?

• Resolve `strace` file number to a filename

  - by Mike Pennington

  I am debugging a problem where MoinMoin on CentOS is throwing a permissions error, but I can't track down where the problematic file / directory is. I ran strace -vp <pid> on the apache pid; when I have the problem I see this: epoll_wait(10, {{EPOLLIN, {u32=3487534344, u64=140367313734920}}}, 2, 10000) = 1 accept4(6, {sa_family=AF_INET6, sin6_port=htons(52621), inet_pton (AF_INET6, "::ffff:105.193.30.91", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, [28], SOCK_CLOEXEC) = 11 ## Later on... read(7, 0x7fffa658ad7f, 1) = -1 EAGAIN (Resource temporarily unavailable) However, since apache is already running, I see no corresponding open() on the file referred to as 7; thus I see the permissions problem, but I still don't know which file is the problem. I know I could try to catch all the file opens when I respawn apache, but I'm hoping there is a way to map file 7 to a real filename... is there a way to do this?

• .NET Database application guidance.

  - by Wally

  Hello, I'm stumbling in the data wilderness and feel very lost, so i am asking for help. I have done some database apps in VS (C#) winforms for some time, wpf lately. These are small to medium apps (embedded dbs, a bit of sql server), like a restaurants, cash registers and similar. (15-20 tables) Until now, i have done all my datasets by drag and drop in Visual Studio designer. I spent weeks on web trying to find some complete solution how to write complete solution with typed datasets by hand from scratch (DAL, B.Objects) in hope to learn some architecture patterns along the way, but without success. So, finally question. Can someone recommend me what to learn for this type of applications, maybe move away from datasets , use some ORM ( maybe overkill, i dont know). Point me in some direction please.

• What is the weirdest language you have ever programmed in?

  - by sfoulk526

  For me, it was Forth, way back at the end of the eighties! Yes, almost prehistory. But I was an un-degree-ed programmer, unable to afford college, self-taught C and Assembly, and not enough experience to open doors. I was invited to work in software engineering, my dream job by the engineering manager of my company, but...I had to do it in Forth, and the company was willing to teach me. The position was my start into embedded systems programming, and man did I learn a lot! Like, just how easy C and Assembly language REALLY could be! But it was a good journey, and though I never coded again in Forth, my fear of not being able to learn C and Assembly proficiently disappeared... ;-)

• embedding a slideshow photo gallery with Picasa that autorepeats?

  - by user248237

  how can I modify the embedded photo gallery slideshow from Google's Picasa to auto repeat the pictures, i.e. play them over and over again? This is the code Picasa gives me for embedding in a website: <embed type="application/x-shockwave-flash" src="http://picasaweb.google.com/s/c/bin/slideshow.swf" width="400" height="267" flashvars="host=picasaweb.google.com&hl=en_US&feat=flashalbum&RGB=0x000000&feed=http%3A%2F%2Fpicasaweb.google.com%2Fdata%2Ffeed%2Fapi%2Fuser%2F102341124641778821128%2Falbumid%2F5469290618448219537%3Falt%3Drss%26kind%3Dphoto%26hl%3Den_US" pluginspage="http://www.macromedia.com/go/getflashplayer"> Related to this, are there free tools that take as input a Picasa username or a set of photos and automatically create a thumbnailed gallery, which is embeddable using Flash in any website? thanks.

• Error handling and polymorphism

  - by Neeraj

  I have an application with some bunch of code like this: errCode = callMainSystem(); switch (errCode){ case FailErr: error("Err corresponding to val1\n"); case IgnoreErr: error("Err corresponding to val2\n"); ... ... default: error("Unknown error\n"); } The values are enum constants. Will it make some sense to have something like: // Error* callMainSystem() ... Some code return FaileErr(); // or some other error // handling code Error* err = callMainSystem(); err->toString(); The Error class may be made singleton as it only has to print error messages. What are the pros and cons of above methods,size is an important criteria as the application needs to be supported on embedded devices as well. P.S: I don't want to use exception handling because of portability issues and associated overheads.

• Pros and cons of keeping metadata in image thumbnails

  - by SODA

  I am working on optimizing site load speed for a few moderately high traffic sites. Some quick observations show that creating 40 picture thumbnails (e.g. 138x138 JPG @75% quality) results in 700 Kb total size with embedded metadata and 258 Kb with stripped metadata. Which means that roughly 60% of image size is metadata. So what would be pros and cons of removing metadata from thumbnails? Are there any regulations, e.g. you must keep author info / copyright info in the images? Any insights would be appreciated.

• iOS app rejected by itunes team for copyright when embedding video from youtube

  - by Thiru Subramaniam

  I have created a simple app for my client with his selection of youtube videos embedded via iframe player and html5. The app got approved in android store whereas itunes rejected it claiming below, "Apps may not use protected third party material such as trademarks, copyrights, patents or violate 3rd party terms of use. Authorization to use such material must be provided upon request" Below is the link for the app in android. https://play.google.com/store/apps/details?id=com.jayam.shortfilms While I share videos using the html code obtained from youtube share button, still apple is claiming that I should provide evidence of copyright from each video owner. Any experiences of this kind will be very helpful for me.

• ssrs column groups disable multiple columns

  - by DKS

  I'm using ASP.NET 4.0 Visual Studio 2010 RC version Sql Server Report Services (SSRS) ReportViewer and are aware that columns only display on PDF export - not the preview. I want to use a matrix embedded in a table on a page that has multiple columns. I've done some testing and frustratingly found that if you have a tablix with at least one grouped column (even if there is only one displayed matrix-like column group) the columns seem to be disabled. Once I remove the tablix with a grouped column from the tablix from the report the report does multiple-columns. Does anyone know a way around this?

• How to make your website works on a projector?

  - by iyad al aqel

  I have a presentation tomorrow, and while I was trying to project my website using projector all the elements appeared mixed up. The problem is I used a software called "AXURE" to do the website. The HTML files produced by this software are crap. There's no one unified CSS file. The style is embedded for each element in the <div> tag and every element is positined by absolute pixels. How can make my website works on larger screens?

• Installing DB2 in Windows 2003 Cluster

  - by radoslawc

  How can I install db2 with already created domain user? Or maybe there is no need, just install with local user db2admin and then create instance using existing domain user? This is how it looks I've got win 2003 cluster single quorum, I have to move db2 database to another cluster in same domain. I've added resources to new cluster like in IBM redbook, and I have problem adding db2 resource. I've got service account DOMAIN\serviceaccount and DOMAIN\db2_instance owner, to install db2 do I have to log in as db2_instance_owner? Thanks in advance

• Validating/Allowing YouTube Embed Code

  - by mellowsoon

  Hi, hopefully this is a simple question. I have a simple custom forum on my site written in PHP. For security reasons I don't allow any HTML in the forum posts. I only allow certain BBCode tags. I would however like to allow embedded YouTube videos. So my question is this: What's the best (most secure) way to validate the YouTube embed code? YouTube is currently using iframes to embed videos, but obviously I can't just allow the iframe tag. I also need to ensure the src of the iframe is a YouTube URL, and ensure there's no other malicious bits of code in the iframe code.

• Determine display or VNC session based on PID

  - by Daniel Kessler

  I frequently VNC into a server where we run many concurrent computationally intensive matlab processes. Sometimes, one of my processes misbehave, which I can see from top, but I have a hard time figuring out which VNC session it's running on, or more specifically, which display it's running on. Suppose I see that PID 8536 looks like a resource hog, and I want to investigate. Because it's a matlab session, I know there is likely an IDE open somewhere, and I want to check to see if anything important is happening before I kill it. We've solved this somewhat awkwardly in the past by identifying which PTY 8536 was launched from, then looking at a process tree to figure out things launched in that context, scrolling up, and seeing the VNC initialization. Seems like there must be a better way to go PID - X Display (or VNC Session).

• Tomcat's connection pool opens only 20 connections to mysql

  - by stck

  I have a java application with following line in context.xml <Resource driverClassName="com.mysql.jdbc.Driver" maxActive="100" maxIdle="30" initialSize="10" maxWait="7000" name="jdbc/app" password="pass" type="javax.sql.DataSource" url="jdbc:mysql://dbhost:3306/dbname?autoReconnect=true" username="user" validationQuery="SELECT 1" removeAbandoned="true" removeAbandonedTimeout="30" logAbandoned="true" /> In mysql 'show variables' tells me that max_connections is 151. Still, use information_schema; select count(*) from processlist where User = 'user'; never shows me more than 20 connections. On tomcat's catalina.out -log I get Caused by: org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot get a connection, pool exhausted at org.apache.tomcat.dbcp.dbcp.PoolingDataSource.getConnection(PoolingDataSource.java:103) at org.apache.tomcat.dbcp.dbcp.BasicDataSource.getConnection(BasicDataSource.java:540) at org.springframework.jdbc.datasource.DataSourceUtils.doGetConnection(DataSourceUtils.java:113) at org.springframework.jdbc.datasource.DataSourceUtils.getConnection(DataSourceUtils.java:79) What should I check for to find the problem?

• Avoiding jagged text when pasting into vi?

  - by overtherainbow

  Hello Although I have no problem using SecureCRT (5.1.2 build 274) to work from Windows and connect to PC's running Linux, I have a problem when connecting to an embedded Asterisk appliance that provides"vi" through BusyBox 1.4.1 (2008-03-10). The issue I'm having, is that when I paste code into vi, the text appears jagged like this: <?php try { $dbh = new PDO("sqlite:./db.sqlite"); $dbh->exec("CREATE TABLE IF NOT EXISTS customer (id INTEGER PRIMARY KEY AUTOINCREMENT, name VARCHAR(255))"); Does someone what the problem is? Is there a way to reconfigure either BusyBox or SecureCRT so that I can paste successfully? Thank you.

• Using typedefs (or #defines) on built in types - any sensible reason?

  - by jb

  Well I'm doing some Java - C integration, and throught C library werid type mappings are used (theres more of them;)): #define CHAR char /* 8 bit signed int */ #define SHORT short /* 16 bit signed int */ #define INT int /* "natural" length signed int */ #define LONG long /* 32 bit signed int */ typedef unsigned char BYTE; /* 8 bit unsigned int */ typedef unsigned char UCHAR; /* 8 bit unsigned int */ typedef unsigned short USHORT; /* 16 bit unsigned int */ typedef unsigned int UINT; /* "natural" length unsigned int*/ Is there any legitimate reason not to use them? It's not like char is going to be redefined anytime soon. I can think of: Writing platform/compiler portable code (size of type is underspecified in C/C++) Saving space and time on embedded systems - if you loop over array shorter than 255 on 8bit microprocessor writing: for(uint8_t ii = 0; ii < len; ii++) will give meaureable speedup.

• syntax to express mathematical formula concisely in your language of choice

  - by aaa

  hello. I am developing functional domain specific embedded language within C++ to translate formulas into working code as concisely and accurately as possible. Right now my language looks something like this: // implies two nested loops j=0:N, i=0,j (range(i) < j < N)[T(i,j) = (T(i,j) - T(j,i))/e(i+j)]; // implies summation over above expression sum(range(i) < j < N))[(T(i,j) - T(j,i))/e(i+j)]; I am looking for possible syntax improvements/extensions or just different ideas about expressing mathematical formulas as clearly and precisely as possible. Can you give me some syntax examples relating to my question which can be accomplished in your language of choice which consider useful. In particular, if you have some ideas about how to translate the above code segments, I would be happy to hear them Thank you

• nginx + IIS + GET

  I have nginx on pc "A" & IIS with ASP.NET on pc "B". nginx is configured like this: ... location ~ ((Web|Script)Resource.*)$ { proxy_pass "B"/$1; proxy_redirect off; proxy_set_header REMOTE_ADDR $remote_addr; proxy_set_header REQUEST_URI $request_uri; proxy_set_header HTTP_REFERER $http_referer; #proxy_set_header REQUEST_URI $request_uri; proxy_set_header QUERY_STRING $query_string; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $http_host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; }... but requests to "B"/WebScript?a=b&c=d aren't able to deliver GET data (a=b&c=d) to IIS part. Could anyone help with this?

• How do you run your unit tests? Compiler flags? Static libraries?

  - by Christopher Gateley

  I'm just getting started with TDD and am curious as to what approaches others take to run their tests. For reference, I am using the google testing framework, but I believe the question is applicable to most other testing frameworks and to languages other than C/C++. My general approach so far has been to do either one of three things: Write the majority of the application in a static library, then create two executables. One executable is the application itself, while the other is the test runner with all of the tests. Both link to the static library. Embed the testing code directly into the application itself, and enable or disable the testing code using compiler flags. This is probably the best approach I've used so far, but clutters up the code a bit. Embed the testing code directly into the application itself, and, given certain command-line switches either run the application itself or run the tests embedded in the application. None of these solutions are particularly elegant... How do you do it?

• iPhone, special characters in JSON Response

  - by eddit

  Writing an iphone app, and I'm getting my data from a REST API that returns JSON. My problem is, some of the data has special characters embedded and Im getting errors. Example: MartÌn Petite-RiviËre-Saint-FranÁois Here is my current code: NSString *jsonString = [[NSString alloc] initWithData:receivedData encoding:NSUTF8StringEncoding]; NSMutableArray *tempResults = [[[jsonString JSONValue] objectForKey:@"getRegionResortsLastUpdatedResponse"] objectForKey:@"return"]; Whenever the data has special characters in it "jsonString" return "(null)", otherwise everything works fine. Is this something I can handle on my end, or does the API need to be modified to output the character codes?

• Kerberos authentication between 2 applications

  - by Spivi

  We work on a server 2003 and server 2008 R2 enviroment. I'm familiar with the basic usage of the Kerberos protocol where the protocol authenticates a client when he tries to use a shared resource (server, folder, printer, etc.). We have three distinct and independent .NET applications that we develop inhouse (app A, app B & app C) but they need to communicate for a given reason (A recieves messages only from B and C and C recieves messages only from B). Is it possible to configure the Kerberos services to authenticate messages/request between two .NET apps ? (Instead of a user-server authentication, we will have an application-application authentication)

• How can I merge CSS definitions in files into inline style attributes, using Perl?

  - by mintywalker

  Many email clients don't like linked CSS stylesheets, or even the embedded <style> tag, but rather want the CSS to appear inline as style attributes on all your markup. BAD: <link rel=stylesheet type="text/css" href="/style.css"> BAD: <style type="text/css">...</style> WORKS: <h1 style="margin: 0">...</h1> However this inline style attribute approach is a right pain to manage. I've found tools for Ruby and PHP that will take a CSS file and some separate markup as input and return you the merged result - a single file of markup with all the CSS converted to style attributes. I'm looking for a Perl solution to this problem, but I've not found one on CPAN or by searching Google. Any pointers? Alternatively, are there CPAN modules one could combine to achieve the same result? Ruby http://code.dunae.ca/premailer.web/ PHP http://www.pelagodesign.com/sidecar/emogrifier/ Perl ?

• How to Generate Embeddable Widgets, and Return PartialView, JS & CSS as JSONP?

  - by DaveDev

  I found this question which is a great starting point towards creating embedded widgets that enable showing dynamic content on remote sites (i.e. a different domain). One problem I'm having is with the following code: public ActionResult SomeAction() { return new JsonpResult { Data = new { Widget = "some partial html for the widget" } }; } It says Widget = "some partial html for the widget" but this doesn't really mean anything to me. I assume that Widget would contain the HTML representing what the user wants to see on the screen, but How do I get the contents of my Partial View into Widget? Can anyone point me in the right direction? Thanks..

• VLC helper protocol on Mac OS X

  - by Preben

  Hey everybody, I am trying to add a vlc:// helper protocol on Mac OS X. To register the protocol, I have unsuccessfully been playing around with the MoreInternet PrefPane. What I want to have in my browser is a vlc://someressource.com/audio.mp3, which should launch VLC and add http://someressource.com/audio.mp3 to the playlist (this works fine on Windows and also Linux if I remember correctly). Maybe even just have vlc://http:// so that https would also be supported. I have no idea how to achieve this. I tried making a bash script, which MoreInternet would not accept. Then I tried making an application through Automator with my Bash script embedded. That did not work either, as the Automator application has no "creator code" - whatever that is?! Can any of you guys point me in the right direction? Thanks in advance!

• Accessing C$ over LAN on Win2008R2 - cannot by hostname but can by IP and FQDN

  - by Idgoo

  Having an issue with one of our Win2k8 R2 file servers. Trying to access C$ or the Admin share is giving us an error (see error details that the bottom), however we are able to connect using the server's IP and FQDN. can access \\172.16.x.x\c$ with domain cred can access \\server.domain.local\c$ with domain creds cannot access \\servername\c$ with same domain creds Server pings fine with Hostname, IP, FQDN, the Primary DNS suffix is also correct. DNS, PTR and Wins records are all correct for the Server I have checked that I am not trying to connect with cached credentials in the Windows vault, the server is also appending primary and connection specific DNS suffixes to the hostname. Any ideas what might be causing this issue? Error Details: c$ is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions
