• How to clear stuck locked maildrop pop3 process

  - by Joshua

  I am using cyrus for imap and pop One of my users is getting the following error: Unable to lock maildrop : Mailbox is locked by POP server. I can see where it starts in the log. I've read that there is no physical lock file anymore (i've tried looking for it anyways) and that the solution is to just wait for the timeout, or kill the offending pop3 process. I know that this is happening because of a lossy connection on the part of the affected user, and that pop3 can only have 1 session active at a time. I need to manually clear the lock and I am having trouble finding the offending pop process. I have tried lsof, but it doesn't say how long the individual files (sockets) have been opened for. I've reduced the tcp keepalive time down to 5 mins, but I still need to reset this guy's lock. I could use some pointers. Thanks!

• How to stop Bash appending history

  - by Craig

  I am having a lot of trouble setting up the terminal history of Bash the way I want. I would like to have no duplicate entries and if I enter a command I want it saved and the duplicates above removed. The problem is the history command shows me it is functioning the way I want however once I log out the duplicates come back again. I believe it is just appending the history to the existing one. I have these lines in my .bashrc file (~/.bashrc) HISTCONTROL=ignoreboth:erasedups shopt -u histappend I have even tried uncommenting shopt but it still appends the history on logout. How can I have the history be exactly how it is before I logout?

• What could cause Vista machines to degrade in performance?

  - by gencha

  We have installed several machines running Windows Vista at a client site. These machines run the same set of applications each day and are not operated with by any user. They mainly run a 3D application for digital signage purposes. After a few months I noticed that several machines suffer from really bad stuttering. The performance is unacceptable. At first I figured it was faulty hardware. But after putting a fresh image on them, they run perfectly fine again. These are Core i7 machines with GTX 280 graphics adapters. They should be able to handle the workload without any trouble (and they do, at least for a while). I really have no idea how to track down the source of this issue. Especially since not all of the machines display the same issue.

• Calling a method in a view controller from a view

  - by Lakshmie

  I have to invoke a method present in a view controller who's reference is available in the view. When I try to call the method like any other method, for some reason, iPhone just ignores the call. Can somebody explain as to why this happens and also how can I go about invoking this method? In the view I have this method: -(void) touchesBegan :(NSSet *) touches withEvent:(UIEvent *)event{ NSArray* mySubViews = [self subviews]; for (UITouch *touch in touches) { int i = 0; for(; i<[mySubViews count]; i++){ if(CGRectContainsPoint([[mySubViews objectAtIndex:i] frame], [touch locationInView:self])){ break; } } if(i<[mySubViews count]){ // viewController is the reference to the View Controller. [viewController pointToSummary:[touch locationInView:self].y]; NSLog(@"Helloooooo"); break; } } } Whenever the touches event is triggered, Hellooooo gets printed in the console but the method before that is simply ignored

• Freezing with black screen after booting OS with AMD Catalyst driver

  - by Oleg

  I have ATI Mobility Radeon HD 5470 on my HP laptop. A few weeks ago I was confused with a weird trouble in proprietary drivers for my graphics card. When I start X server (or just boot Windows) system sometimes totally hangs up with black screen. The most annoying thing is that issue appearing is absolutely random (2 success, 3 fails, 1 success, 7 fails, etc.). It appears both on Linux (Arch, Debian 7) and Windows XP. I've tried reinstalling OS, drivers, etc. I've also tried updating BIOS. Then boot was successful for the next few times and issue appeared again (probably it was just a coincidence, because another BIOS updates gave no results). I really don't know what to do. Any ideas?

• LocalUser access for WCF hosted in IIS

  - by Eugarps

  I have tried every combination to allow unauthenticated access to WCF as in "LocalUser" accounts, in IIS without success. Here is what I've most recently tried: wsHttpBinding with Message security and mode set to "None". IIS anonymous access enabled, all others disabled, folder level access at default (but granted read access to "Users" which is all users in our domain). I understand I may not have provided enough information to solve the issue, but perhaps somebody can point me in the right direction - is this likely to be a IIS configuration issue or a WCF configuration issue... if WCF, is it likely to be a client level or server level issue? The error I get when attempting to access here is "User is not authenticated". We have ASMX services in the domain which are behaving properly, I am the first developer using WCF here.

• How do I draw part of parabola using iText ? Or how do I create quadratic bezier curves from cubic b

  - by drasto

  I need to draw a shape whose boundaries are parts of parabola (that is quadratic bezier curves) using iText. I have found only method for drawing cubic bezier curves in PdfContentByte class. So how do I draw quadratic bezier curves using iText ? One way would be to use method for cubic bezier curves. Is it possible to draw quadratic bezier curves as a cubic bezier curves (with 2 control points). I gues it is but I cannot make up the formula. If somebody states the formula tu "translate" cubic bezier curves to quadratic that would solve the problem. Any other ways to draw quadratic bezier(parts of parabola) curves in iText (and filled shapes made of them) is also the solution. Thanks

• .Net Compact Framework 2.0 touch and nice controls

  - by eridem

  Hello! I would like to know if somebody knows free custom nice controls for .NET Compact Framework 2.0. There are nice controls as Manila Interface SDK (http://forum.xda-developers.com/showthread.php?t=566188), Sense Interface SDK (http://forum.xda-developers.com/showthread.php?t=648906) and so on for free, but they work only on .NET CF 3.5. Furthermore, there are others that you have to pay for them and for .NET CF 2.0 and 3.5 (Resco or Touch Control Suite). And there is one called Fluid (http://fluid.codeplex.com/) but it's so complicated, there are not exactly controls (are classes added to a host control) and there is not much documentation to work with it. Any nice controls for free and working in .NET CF 2.0? And with list sliders if it's possible? Thanks!

• How do I use a virtualbox guest machine as a gateway?

  - by Igor Zinov'yev

  I have a certain problem. I am working on an Ubuntu machine, but I have to use a windows 2003 server guest to connect to a Stonegate VPN to be able to manage our client's website. I have already asked if I could connect to a Stonegate VPN in Ubuntu, but so far got no answer. And I couldn't connect to it using network manager's strongswan plugin. So I want to use my guest Win2003 as a gateway to be able to SSH to the remote server. Is that possible? Thank you very much in advance, if this is possible in any way, it will save me a lot of trouble!

• HMM for perspective estimation in document image, can't understand the algorithm

  - by maximus

  Hello! Here is a paper, it is about estimating the perspective of binary image containing text and some noise or non text objects. PDF document The algorithm uses the Hidden Markov Model: actually two conditions T - text B - backgrouond (i.e. noise) It is hard to understand the algorithm itself. The question is that I've read about Hidden Markov Models and I know that it uses probabilities that must be known. But in this algorithm I can't understand, if they use HMM, how do they get those probabilities (probability of changing the state from S1 to another state for example S2)? I didn't find anything about training there also in that paper. So, if somebody understands it, please tell me. Also is it possible to use HMM without knowing the state change probabilities?

• Getting memory section information

  - by Basilevs

  Can somebody explain me how the following code works? # if defined(__ELF__) # define __SECTION_FLAGS ", \"aw\" , @progbits" /* writable flag needed for ld ".[cd]tors" sections bug workaround) */ # elif defined(__COFF__) # define __SECTION_FLAGS ", \"dr\"" /* untested, may be writable flag needed */ # endif asm ( ".section .ctors" __SECTION_FLAGS "\n" ".globl __ctors_begin__\n" "__ctors_begin__:\n" ".previous\n" ); asm /* ld ".[cd]tors" sections bug workaround */ ( ".section .ctors0" __SECTION_FLAGS "\n" ".globl __ctors0_begin__\n" "__ctors0_begin__:\n" ".previous\n" ); Similarly we are getting __ctors_end__ , __ctors0_end__ and destructors location is also obtained this way. After some ld bug workarounds all functions pointed by pointers from __ctors_begin__ to __ctors_end__ are executed. I don't know assembler and this code is impossible for me to interpret. BTW: I know that invoking C++ contructors/destructors from C is not a task to be considered safe or easy.

• Compiling a C program with a specific architecture

  - by Marplesoft

  I was recently fighting some problems trying to compile an open source library on my Mac that depended on another library and got some errors about incompatible library architectures. Can somebody explain the concept behind compiling a C program for a specific architecture? I have seen the -arch compiler flag before and have seen values passed to it such as ppc, i386 and x86_64 which I assume maps to the CPU "language", but my understanding stops there. If one program uses a particular architecture, do all libraries that it loads need to be on the same architecture as well? How can I tell what architecture a given program/process is running under?

• What's the future of std::valarray look like?

  - by andand

  Up until fairly recently I hadn't been keeping up with the C++0x deliberations. As I try to become more familiar with it the issues being worked, I've come across sites like this which seems to be advocating for deprecating or removing std::valarray since most people are using Blitz++ in any event. I guess I'm probably one of the few people out there who uses std::valarray (and yes I know the class has a sordid past, a tarnished present, and a questionable future). For me they work, and perhaps more important, they're part of the standard (for now any way). Aside from the one site above, I've been able to find very little on what is actually happening with std::valarray in the new standard, and was hoping that somebody on SO might be able to provide some insight and / or references where Google, Wikipedia and even the C++ Standards Committee Web Site have so far failed me. Thanks.

• Flash not interacting with Javascripts in browser inside my app

  - by Shivaprasad

  Hi , I have an application which embeds a xulrunner based browser. I have to load some flash content in it which talks to some javascripts to update the browser title. The flash content works fine when launched from Firefox but not inside my app. I tried a sample html file which has some javascripts and they work fine. It even works when I have the flash content on a server. It is only when I try to run js through flash present on my local machine that I see this problem. I guess it must have something to do with some security settings in xulrunner. Could somebody help me figure out what the problem might be? Thanks jbsp72

• What steps put my bash prompt commands into vim and then back again to bash to execute?

  - by xtian

  I've enabled VIM style editing of bash commands at the bash prompt as default bash setting. On a few occasions I've accidentally opened a blank vim file with some complex bash command I was writing. Awesome. How do I get the newly written line in vim back into bash? I found another post where the author had the opposite trouble--or so it seems. What steps put my bash prompt commands into vim and then back again to bash to execute?

• PERC 5/i Enable alarm on disks failures

  - by Andy M

  I'm trying to enable one the alarm of my server's raid controller PERC 5/i. Using this documentation, under the chapter Audible Alarm Warnings, it's explained that enabling an audible alarm is allowed in order to quickly spot failures on my hard disks. My trouble is that when entering the disk controller configuration (Ctrl+R at boot time), I'm able to set up lot of things but I cannot navigate to Enable Audible Alarm. I have : Enable Controller BIOS Enable Alarm Enable BIOS stop on Error I can navigate with my arrow keys to both the first and third items, but I cannot navigate to or select the second! It's not greyed out, and seems like I should be able to select go on this entry, but my cursor keep skipping it. Any ideas about what I'm missing here?

• Transfer files using java

  - by markovuksanovic

  I need to transfer lots of small files to a remote computer within my java program. I was wondering if somebody could suggest the best way to do so... I need to transfer lots of small files and it has to be really fast. Should I use some existing protocol implementation? maybe ftp? One important thing is that most files would be the same all the time, or the difference would be minor so I was thinking of using git for that purpose. Does anyone have experience with sth like this?

• Running Python scripts in a browser

  - by sunwukung

  I want to start learning Python - and I'm having trouble getting scripts to load up in a browser (using Wamp). So far I've tried the following: 1: add the following lines to httpd.conf: AddHandler cgi-script .py Options ExecCGI I navigate to localhost/path/to/script/myscript.py but get an Internal Server error. 2: downloaded mod_wsgi-win32-ap22py26-3.0.so - renamed to mod_wsgi (running Wamp with Apache 2.2) added the following lines to httpd.conf AddHandler mod_wsgi .py WSGIScriptAlias /wsgi/ "path/to/my/pythonscripts/folder/" but when I navigate to the script - it renders the script in it's entirety i.e. #!c:/Python26/python.exe -u print "hello world" I managed to get CherryPy working, but ideally I want to learn the language in a relatively raw context before digging into a framework. Can anyone give me some pointers?
