• How can I de-install a Perl module installed via `cpan`?

  - by Kinopiko

  I am using Perl running in user space (not installed via root) and installing modules via the command-line cpan. I would like to know if there is a simple way to remove a module without having to do a lot of work deleting individual files. I searched for this question on the internet and found some answers, but the answers I've found seem to either discuss using the Perl package manager (specific for Microsoft Windows), otherwise operating-system specific (BSDpan), suggesting using cpanplus (which I've had several bad experiences with), or ended by pointing to a dead link as follows: http://www.cpan.org/misc/cpan-faq.html#How_delete_Perl_modules. My question is specifically whether there is a clean way to remove a module installed via cpan.

• UIDatePicker in UIDatePickerModeCountDownTimer mode: how to get/set the hours and minutes via code?

  - by R31n4ld0

  Hello, guys. How to get/set the hours and minutes via code from a UIDatePicker in UIDatePickerModeCountDownTimer mode? The situation: I have an interface in that a user selects just hours and minutes. Then, he saves the information (so, I have to get the hours and minutes from UIDatePicker via code to save in a DB). When the user is editing the information saved previously, I want to start the interface with the saved hours/minutes (so, I have to set the UIDatePicker hours and minutes retrieved from DB via code). How do I do that with the UIDatePiker in UIDatePickerModeCountDownTimer mode? Thanks in advance.

• Best method to cleanly shut down an application launched via another.

  - by JYelton

  I couldn't find any close answers to this, so I'm consulting the experience of SO users: Scenario: I have two small C# winforms applications where one behaves as a server or host, the other as a client. They share data via SQL Server, in terms of configuration settings. I am currently launching the client application (which only needs to run periodically) from the server application via Process.Start() and terminating it via Process.CloseMainWindow() (after finding it in the process list). While it seems clean enough, I wondered if there's a better way. Question: Which way would be best to instruct the client application to shut down: Continue using Process.CloseMainWindow()? Implement WCF between the applications? (I would need help on how to do this.) Set a variable in SQL that the client application checks for? Some other way?

• Issues rendering image in flash via Context.Response.Write C# asp.

  - by Justin

  I am having an issue rendering images in flash via a character array. I am sending it from a webhandler via Context.Response.Write as a Base64CharacterArray. It functions 100% properly in a windows environment, however when using a Mac the image data is not retrieved correctly causing the image to appear incorrectly. It does not affect the data,however as it is rendered properly in a player which accesses the data via a webservice. I am at the end of my rope on this one. Anything will help. You can find an example at the following url http://www.discoverirelandtoday.com/photoalbum/Public/Main.aspx Thanks

• Get class of caller's method (via inspect) in Python; or: super(Class,self).method() replacement wit

  - by Slava Vishnyakov

  Is it possible to get reference to class B in this example? class A(object): pass class B(A): def test(self): test2() class C(B): pass import inspect def test2(): frame = inspect.currentframe().f_back cls = frame.[?something here?] # cls here should == B (class) c = C() c.test() Basically, C is child of B, B is child of A. Then we create c of type C. Then the call to c.test() actually calls B.test() (via inheritance), which calls to test2(). test2() can get the parent frame frame; code reference to method via frame.f_code; self via frame.f_locals['self']; but type(frame.f_locals['self']) is C (of course), but not B, where method is defined. Any way to get B?

• How can I read out the CSS text via Javascript as defined in the stylesheet?

  - by Monokai

  I was thinking of using Javascript to automatically transform CSS3 attributes like border-radius, transform, box-shadow, etc. to their browser specific counterparts. I did some research and found that you can iterate over the stylesheets defined via document.styleSheets. You can find the CSS rules via document.styleSheets[0].cssRules[0].cssText. I want to modify the CSS rules that contain CSS3 attributes by injecting the browser specific attributes with the appropriate vendor-prefix, like -webkit-border-radius, moz-border-radius, etc. However, it seems that the cssText property is preprocessed in each browser, to filter out CSS attributes that it doesn't understand. That practically breaks this idea. Question: is there any way to retrieve the CSS text exactly as defined in the stylesheet? Or: is there another way to accomplish this via Javascript? I'd like to maintain clean CSS files without the need for defining each attribute multiple times for each specific browser.

• Is it possible to change the mount point used for external USB devices from /media to something else under GNOME?

  - by slm

  I'm using CentOS 5.x and am trying to change the mount point that get's used when I insert a USB thumb drive or external USB drive. They're showing up under /media/KINGSTON for example. I'd like to change this so that they show up under /external/KINGSTON for example. If you must know my reasons for asking this, I have a domain where they're already using /media for something else and it would be more work to move this domain's automount from /media to something else. I'm trying to explore all my options before I decide on a path forward. Thanks!

• How can I configure a NameCheap domain to point to an Apache subfolder? [closed]

  - by Serg

  Possible Duplicate: How to make domain point to another web directory? My boss just bought the domain: sergiotapia.me for me, and agree'd the host my Wordpress blog on company servers. We're using Apache (latest version). The domain is purchased on NameCheap.com and the DNS settings are as follows: And when I visit my URL, it's getting redirected to my VPS server without problems. The thing is, I want my blog to appears at once, not have a user select the folder and then see the blog. My Wordpress blog is located at: /var/www/sergiotapia.me On IIS, you would need to edit the Bindings and map a domain to an application. I'm guessing I have to do something similar on Apache. What am I looking for here? Any tips on getting this working correctly?

• KMS / Office 2010... please point to documentation.

  - by TomTom

  Trying to find out how to "modify" KMS to also accept the Office 2010 KMS key. Can anyone point me to some document about this? Basically - do I have to install an update to KMS? I wand my KMS server to authenticate both, Windows (It currently has a DataCenter R2 KMS key installed) as well as Office 2010. Keys are available ;) I can not imagine I just ptu it in - would this not overwrite the DataCenter key? I tried the MSDN website, but there is no clear document visible for my question.

• Can I buy a wireless access point that also acts as a DNS nameserver?

  - by Brabster

  Hi, I was wondering if I buy a wireless access point/router that also acts as a DNS nameserver for DHCP clients. I can see the hostnames of my home devices in the DHCP clients table of the router I have, it doesn't seem like a great leap of the imagination to have a local nameserver on there, something like hostname.home that automatically publishes those entries to a local zone. But - I can't find one that does that. Is there a reason why this shouldn't/can't be done? Or is my Google-Fu just weak? Cheers,

• Is there a point to using theft tracking software like Prey on my laptop, if you have login security?

  - by Reckage

  Hey, so I have a Thinkpad that I use in a variety of places (coffee shops, work, etc.). I don't generally abandon it, but I figure there's a chance I might get careless and it gets stolen at some point. I was thinking of installing something like Prey (http://preyproject.com/), but my OS installs are password secured, and on top of that, I have a fingerprint reader that you need just to get through the BIOS. So: is there actually any benefit to setting up software that tracks the laptop's whereabouts? I imagine that either: The laptop won't boot or login, if the thief doesn't get past the security. If the thief goes around said security somehow, presumably they've split the laptop for parts or bypassed BIOS security, gotten stuck on Windows security and formatted it. Given that it's highly unlikely that the thief would go to the trouble, what's the utility in installing laptop tracking software like Prey?

• Can you link an NTFS junction point to a directory on a Network Attached Storage?

  - by Zachary Burt

  I'm using Windows, and I want to use Dropbox to back up a folder outside my Dropbox directory. So I want to create a junction point from my target directory to my Dropbox folder. Accoding to the Wikipedia article on NTFS junction points, which the Dropbox answer links to: "Junction points can only link to directories on a local volume; junction points to remote shares are unsupported." I am looking to link to a directory on networked attached storage, which would not be a local volume, I believe. What should I do?

• Is there anything like a link or shared mount point for FAT32 folders in Linux/Android?

  - by endolith

  I often want the same files to be accessed by different apps on my Android phone, but the apps look in different folders. Is there a way to make two different folder paths on a FAT SD card point to the same file? For EXT, I think I could do this with a symbolic or hard link, but those don't exist for FAT. Can FAT be extended to support them? Can Android use an EXT-formatted SD card? Can a folder be mounted on top of another folder? If this does exist, does it have any negative side effects?

• Is giving read permissions on /etc/shadow to apache user a wise decision from security point of view?

  - by Czar

  I have to use PAM authentication for DAV SVN, but when everything is configured as specified in mod_auth_pam documentation, authentication does not work. After some research I realized, that for this to work, httpd should be running under root user (which I don't like and won't implement) or apache user (under which httpd is running by default) should have permissions to read /etc/shadow file. So there is a pair of questions connected to each other which I want to ask: Is giving this permition to apache user a wise decision from security point of view? If answer to the first question is "yes", what is the correct way to do so? For now I've done following: groupadd shadow usermod -G shadow apache chmod g+r /etc/shadow Another way I can come up with is using acl: setfacl -m u:apache:r /etc/shadow Note: OS is Fedora 14 x86_64 (kernel: 2.6.35.11) httpd v2.2.17 mod_auth_pam v1.1.1

• LAMP Server without single failure point + Global Server Load Balancing?

  - by José Nobile

  I want implement a LAMP Server (Linux Apache MySQL PHP) without a single failure point and with Global Server Load Balancing. I have a server in Cali, Colombia, and other server will be installed in Melbourne, Australia, user in America can use the Cali Server and in Europe, Asia, Africa or Oceania use the Melbourne Server. If any server fail (or load is excessively high), a server must answer all request. Data in MYSQL must be in sync, php files, any configuration in both server must be in sync. I read about of Google DNS Server 8.8.8.8 and 8.8.4.4 and ANY Cast, also about MySQL semisynchronous replication and MySQL Cluster, but what about other things, as crontabs, and the configurations in server? The solution can't depend of APNIC or BGP, only open source software running in Linux.

• Is there a "restore point" in Linux (Debian/Ubuntu) like Windows?

  - by Somebody still uses you MS-DOS

  I'm working directly in an Ubuntu Virtual Machine (VM). Some updates (like kernel) were available at the update manager. If I weren't using a VM, I wouldn't update it since it's a risk to break something. Since it's a VM, you can create a Snapshot or export an appliance and restore if something goes wrong. Suppose I'm not using a VM with a Debian/Ubuntu installation. Is there a install-restore approach that doesn't depend in a VM configuration to restore your system exactly before an upgrade (Like a "Restore Point" in Windows), being easy to restore like a VM appliance? (I'm not looking for "ghost images" or something like that (Norton Ghost, Clonezilla, etc), I'm looking for something builtin in the Linux System)

• DNS point to server on ISP and keep shared host too?

  - by Dwayne

  I know this is probably quite easy to do, but I might just have the right search sorted out... so here is the situation: We have example.com set up as a hosted server along with app1.example.com, app2.example.com and a few others. What I would like to do is set up the right zone file to also make our internal server addressable from the outside world as internalapp.example.com. This server sits behind a firewall (pfsense) and is hooked up to the world via a cable modem that is technically on DHCP from our ISP, but has had the same external IP for the past 15 months so far. What would be the best way to set this up?

• How can I pin point a USB file transfer bottleneck in Unix?

  - by HankHendrix

  I'm experiencing very slow data transfer speeds over USB 2.0 on my nix box and was wondering how I can pin-point the cause of the problem. I've looked into iotop and top but the cpu and mem figures look normal (compared to guides I have checked). The box which is affected is Ubuntu 12.04 32bit Server running on an Asus EEE 701 2G model and I am transferring from the OS over USB 2.0 to an external HDD (which transfers at 30MB/s+ on Windows 7 on other machine). I get rsync write speeds of 1MB/s from OS to USB HDD which seems ridiculously slow. These speeds are consistent with other USB HDDs and sticks.

• How can I get Google to re-point its search entries to new domain?

  - by poolski

  My main .com domain registration lapsed and when I went to re-register it, I found that a domain reseller service squatted it and I've lost access to it. As I wasn't terribly keen on spending money on funding scammers and the like, I registered a .co.uk domain under the same name. Is there any way of getting Google to re-point all its indexed links to the new domain? It's been indexing my blog for a couple years now and while it's not too big a deal, I'd like to not have to start all over again. Also, searching for my site results in an old entry which is currently pointing at a "Apply for a Tax Break NOW!!!" page.

• How can I have two web roots on one server, so I can point two domains to two different roots?

  - by Daniel F. Dietzel

  I usually ask my n00b questions on Stack Exchange, but now I'm setting up a VPS and have a question. My usual site.com points to my VPS's IP xxx.xxx.xxx.xxx. Now I have a different domain, and I'd like to point that to another location, say xxx.xxx.xxx.xxx/myname. However, when I try to add that as an "A" record in the DNS settings it won't let me. FYI I'm using chicagovps.net with ubuntu 11.10 and Nginx. Thanks!

• What is the mount point for Windows share on Ubuntu 9.10?

  I am new to Ubuntu so please be gentle! I am taking the plunge from Windows!! I connected to a Windows share (using Connect to Server... menu) and I can access it on Gnome just fine. However, I don't know how I can access it in console, or in any other program that requires the path, when it's already connected on Gnome. What's the mount point for that? I tried the mount command but it does not show up.

• How to convert a power point pdf to a pdf that is easy to read on kindle?

  - by SpaceTrucker

  I have several power point presentations as pdfs. I would like to read them on the original kindle in landscape format. When I read the original on the kindle then a single slide won't fit on the kindles display. I thought the easiest way to convert the pdf was to repring it with a pdf printer. However I don't know the paper size to use. I already tried using Calibre as suggested by this question. However the output is not usable because of formatting issues. So what paper size should I use for the pdf printer to reprint them in landscape format or are there any other tools I could use for that task?

• Problem parsing XML data to Multi dimensional array

  - by Cam

  Hi there, i'm still transitioning from as2 to as3, i'm having trouble with parsing XML data to Multi dimensional array, below is the onComplete handler which is succesfully tracing 'event.target.data' but outputs 'A term is undefined and has no properties' when tracing _vein_data[0][0].xPos . I'm guessing there is a easier way to approach it than this attempt private function on_xml_completed(event:Event):void { var XMLPoints:XML = new XML(event.target.data); for ( var i:int = 0; i < XMLPoints.shape.length(); i++ ) { var shapeArray:Array = new Array(); _vein_data.push(shapeArray); for ( var j:int = 0; j < 4; i++ ) { _vein_data[i].push({'xPos':XMLPoints.shape[i].point[j].@xPos, 'yPos':XMLPoints.shape[i].point[j].@yPos}); } } trace(_vein_data[0][0].xPos) loadAsset(); } here's a portion of my XML; <items> <shape> <point xPos="60" yPos="23" /> <point xPos="65" yPos="23" /> <point xPos="93" yPos="85" /> <point xPos="88" yPos="87" /> </shape> <shape> <point xPos="88" yPos="87" /> <point xPos="92" yPos="83" /> <point xPos="145" yPos="174" /> <point xPos="138" yPos="175" /> </shape> <shape> <point xPos="138" yPos="175" /> <point xPos="143" yPos="171" /> <point xPos="147" yPos="211" /> <point xPos="141" yPos="212" /> </shape> </items> thank you in advance for any guidance on this Cam

• How can I detect client-side when a page load is the result of an AJAX history point?

  - by Nick

  I'm trying to prevent a "flicker" effect that is occurring on my ASP.NET page which occurs when a user navigates to the page via the browser back button after having navigated away from it. The reason for the flicker is that I'm using an Update Panel which has some content in there on the initial page-load. As a result, when the page is loaded via a back button that initial content is shown very briefly before it is updated with the correct History-aware data. In order to overcome this I am intending on having the updatepanel hidden (display: none) on inital page load and then show it as long as we don't have any history to deal with. The problem is that I can't find out what to check to determine if there's any history. I can see that the Sys.Application has a _history member but when I'm checking it on page init it is null each time. Does anyone know what I should be checking to determine if there's history to deal with for a page load client-side? And at what point to do it?
