• The premier support for Sun Cluster 3.1 ended

  - by JuergenS

  In October 2011 the premier support for Sun Cluster 3.1 ended. See details in Oracle Lifetime Support Policy for Oracle and Sun System Software document. There no 'Extended Support' and the 'Sustaining Support Ends' is indefinite. But for indefinite 'Sustaining Support' I like to point out from the mentioned document (version Sept. 2011) on page 5: Sustaining Support does NOT include: * New program updates, fixes, security alerts, general maintenance releases, selected functionality releases and documentation updates or upgrade tools * Certification with most new third-party products/versions and most new Oracle products * 24 hour commitment and response guidelines for Severity 1 service requests *Previously released fixes or updates that Oracle no longer supports This means Solaris 10 9/10 update9 is the last qualified release for Sun Cluster 3.1. So, Sun Cluster 3.1 is not qualified on Solaris 10 8/11 Update10. Furthermore there is an issue around with SVM patch 145899-06 or higher. This SVM patch is part of Solaris 10 8/11 Update10. The 145899-06 is the first released patch of this number, therefore the support for Sun Cluster 3.1 ends with the previous SVM patches 144622-01 and 139967-02. For details about the known problem with SVM patch 145899-06 please refer to doc 1378828.1. Further this means you should freeze (no patching, no upgrade) your Sun Cluster 3.1 configuration not later than Solaris 10 9/10 update9. Or even better plan an upgrade to Solaris Cluster 3.3 now to get back to full support.

• Error loading operating system WinXP Pro

  - by Jakesan

  So im getting the error "Error loading operating system" when the computer tries to boot to a fresh install of WinXP Pro. To get to this point, I: Shrunk the only partition with Gparted to 33GB Copied the partition to the end of the 200GB drive Enlarged the first one to fill the space Formatted the first partition to NTFS Set the first partition to boot, tagged the latter to hidden, removed boot flag This was done all under Hiren's BootCD. Now this is where it goes down the drain. I installed XP Pro SP1a from its CD, and chose to quick format the partition. Now after the OS was installed, I can't start XP without using the default menu action from Hiren's BootCD. All I am greeted with is the "error loading operating system" message. I tried to use the XP recovery to fixboot, fixmbr and bootcfg /rebuild (dont remember if the command was like this, anyway the 3 suggested commands). This did nothing. What am I missing here?

• Can a webite have too many bindings?

  - by justSteve

  IIS7.x on a win08 web version on a dedicated server. I have a site that's serving a few dozen affiliates - many of which are hitting me via a subdomain from their own root domain - all of which have a subdomain specific to their account. E.G. my affiliate named 'Acme' hits my site via: myApp.Acme.com (his root, my app) Acme.MyDomain.com (his account within my root domain) Currently I'm adding each of these as a binding entry in IIS (targeting a discrete IP, not '*'). As I ramp this up to include more affiliates I'm wondering if I should be concerned about how many binding this site handles. Proabaly, in Acme's case I can do without the 'Acme.MyDomain.com' because, in reality, all traffic takes place via myApp.Acme.com. Mine is a niche site - very volume compared to most. At what point do I worry about all those bindings? thx

• Which AMI should I use as a base for a Django application?

  - by Edan Maor

  I'm starting development of a Django application, on Amazon's Web Services. I'm looking to build an instance that will serve the Django. I don't have much experience with such things, having only used a shared host before (WebFaction). So I'm wondering, which AMI should I use as a base? I'm assuming I want an Ubuntu AMI, possibly with certain things like Apache pre-installed? One minor point: I'm planning to serve several different Django projects from the same instance. I use virtualenv on my dev machine right now to separate the different projects, I'm assuming I'll do the same on EC2. Thanks!

• Fast Bookmarking In Firefox

  - by Kije

  Making bookmarks in Firefox has become tedious. Can any one point me to a bookmarking extension that works as follows... Decide you want to bookmark a page Left click your way to the target bookmark folder Right the target bookmark folder to get a "Bookmark this page here" option. (It is this "Bookmark this page here" add on that I am looking for) (Edit the book mark title tags etc) Click done Currently you have to: Decide you want to bookmark a page Click on the bookmarks menu pulldown Click on "bookmark this page" Click on the "folder" pulldown Click on "Bookmarks tool bar" or "Bookmarks menu" Left click your way to the target bookmark folder (in a teeny window that that doesn't move the focus as you expand folders) (Edit the book mark title tags etc) Click "Done" That would be four (or five) steps to replace the seven (or eight) steps to make a bookmark in an existing folder. @Chris I assume you are referring me to "Read It Later" http://www.ideashower.com/ideas/launched/read-it-later/ I'll take a look.

• Standard Network Tiers in a Distributed N-Tier System

  Distributed N-Tier client/server architecture allows for segments of an application to be broken up and distributed across multiple locations on a network.  Listed below are standard tiers in a Distributed N-Tier System. End-User Client Tier The End-User Client is responsible for sending and receiving requests from web servers and other applications servers and translating the responses so that the End-User can interpret the data effectively. The primary roles for this tier are to communicate with servers and translate server responses back to the end-user to interpret. Business-Specific Functions Validate Data Display Data Send Data to Webserver Web Server Tier The Web server tier processes new requests for information coming in from the HTTP and HTTPS ports. This primarily handles the generation of user interfaces and calls the application server when needed to access Data and business logic when needed. Business-specific functions Send Data to application server Format Data for Display Validate Data Application Server Tier The application server stores and executes predefined business logic that is applied to various pieces of data as the business determines. The processed data is then returned back to the Webserver. Additionally, this server directly calls the database to obtain and store any data used by the system Business-Specific Functions Validate Data Process Data Send Data to Database Server Database Server Tier The Database Server is responsible for storing and returning all data need by the calling applications.

• Lifecycle of an ASP.NET MVC 5 Application

  Here you can download a PDF Document that charts the lifecycle of every ASP.NET MVC 5 application, from receiving the HTTP request to sending the HTTP response back to the client. It is designed both as an educational tool for those who are new to ASP.NET MVC and also as a reference for those who need to drill into specific aspects of the application. The PDF document has the following features: Relevant HttpApplication stages to help you understand where MVC integrates into the ASP.NET application lifecycle. A high-level view of the MVC application lifecycle, where you can understand the major stages that every MVC application passes through in the request processing pipeline. A detail view that shows drills down into the details of the request processing pipeline. You can compare the high-level view and the detail view to see how the lifecycles details are collected into the various stages. Placement and purpose of all overridable methods on the Controller object in the request processing pipeline. You may or may not have the need to override any one method, but it is important for you to understand their role in the application lifecycle so that you can write code at the appropriate life cycle stage for the effect you intend. Blown-up diagrams showing how each of the filter types (authentication, authorization, action, and result) is invoked. Link to a useful article or blog from each point of interest in the detail view. span.fullpost {display:none;}

• Create an AWS AMI for Ubuntu with GUI which automatically launches web browser

  - by Rory MacDonald

  I've got an ubuntu AMI setup with ubuntu desktop installed and Chrome installed and set to boot on load (via the startup programmes menu within the ubuntu desktop) I've created an image of this AMI, but any time I launch a new instance running this, the Ubuntu GUI doesn't seem to load, until I SSH into the machine, enable VNC and then connect via Chicken VNC to the machine. At that point, the desktop appears to load + starts the browser. I really need the machine to boot and the browser to load without having to VNC into the machine.. Any help would be appreciated.

• Fill a table from a RAND based formula in Excel 2010

  - by Greg Reynolds

  I am trying to do a Monte Carlo simulation using Excel, but a lot of the tutorials I have found are either for older versions of the product, or are not quite what I am after. A simple example of the kind of think I am after is: Cell A1 contains the formula to simulate (for example int(6*rand())+1 to simulate rolling a dice). I have 10 rows of "Trials". What I want is to somehow point each row at a different calculation of the formula in A1. So I would end up with something like Trial Value 1 2 2 5 3 6 4 2 5 1 6 3 7 2 8 4 9 2 10 1 I have tried playing with some of the "What-if Analysis" tools, but I am a bit lost.

• How to pass AppleScripts display dialog to Growl or growlnotify?

  - by pattulus

  I have this simple AppleScript which takes the text in the clipboard and outputs the amount of words and characters used. What I'm trying to do is passing "display dialog" to Growl or growlnotify. I know how to use growlnotify in the shell - it's great and highly customizable (stick note, assign app icon or an image, etc) - but the point is: I don't know how to do it in AppleScript. I google a bit but now time has passed and I decided to post my question here. So, here's the script: set myCount to count (the clipboard) set myWords to count words of (the clipboard) set myParas to count paragraphs of (the clipboard) display dialog "Characters: " & myCount & " Words: " & myWords & " Paragraphs: " & myParas Thanks.

• Windows 7 can't copy file - Error 0x800700DF: The file size exceeds the limit allowed and cannot be saved

  - by JJGroover

  Any attempt to copy files larger than about 40 MB from a network share (a SAN running open filer / Samba) to my local machine running Windows 7 always results in the following error and the copy fails: Error 0x800700DF: The file size exceeds the limit allowed and cannot be saved. I've tried copying to my C: drive and a USB drive with the same results. Smaller files copy just fine. Clearly 40 MB is not that big of a file so I'm assuming it is some buggy interaction between windows 7 and Samba perhaps. Google has so far turned up nothing. Can anyone point me in the right direction?

• How does one check whether the OS X "disabled" flag for launchd services is set?

  - by Charles Duffy

  According to the man page for launchctl (emphasis mine):    -w   Overrides the Disabled key and sets it to false. In previous versions, this option would modify the configuration file. Now the state of the Disabled key is stored elsewhere on-disk. Because the current state of the disabled flag is no longer set in the .plist file itself, checking for the Disabled key is no longer an accurate way to tell if the service will run on next boot. Where is this "elsewhere on-disk"? More to the point (and more importantly), how does one check whether this flag is set? Also, is it possible to set a service to run on next boot without forcing it to start immediately (as with launchctl load -w /Library/LaunchDaemons/my-service.plist)?

• What Is The Formula for the 3 of 9 Bar Code Alphabet?

  - by Chris Moschini

  Background: 3 of 9 Barcode Alphabet A simple syntax for 3 of 9 bar codes What is the formula behind the alphabet and digits in a 3 of 9 bar code? For example, ASCII has a relatively clear arrangement. Numbers start at 33, capitals at 65, lowercase at 97. From these starting points you can infer the ASCII code for any number or letter. The start point for each range is also a multiple of 32 + 1. Bar codes seem random and lacking sequence. If we use the syntax from the second link, this is the first six characters in 3 of 9: A 100-01 B 010-01 C 110-00 D 001-01 E 101-00 F 011-00 I see no pattern here; what is it? I'm as much interested in the designer's intended pattern behind these as I am in someone devising an algorithm of their own that can give you the above code for a given character based on its sequence. I struggled with where to put this question; is it history, computer science, information science? I chose Programmers because a StackExchange search had the most barcode hits here, and because I wanted to specifically relate it to ASCII to explain what sort of formula/explanation I'm looking for.

• Procedural content (settlement) generation

  - by instancedName

  I have, lets say, something like a homework or assignment to do. Roughly said I need to write an algorithm (pseudo code is not necessary, just in depth description) of procedure that would generate settlements, environment and a people to populate it with, as part of some larger world generation procedure. The genre of game is not specified, it could be any genre (rpg, strategy, colony simulation etc.) where interacting with large and extensive world is central to the game. Procedure should be called once per settlement. At the time of calling, world generation procedure makes geography, culture and history input available. Output should be map of the village and it's immediate area, and various potential additional information like myths, history, demographic facts etc. Bonus would be quest ant similar stuff, but that not really my focus at the moment. I will leave quality of the output for later when I actually dig little deeper into this topic. I am free to change parameters as long as I have strong explanation for doing so. Setting of the game is undetermined so I am free to use anything that I like the most. Ok, so my actual question is: Can anyone who has some experience in this field of game design recommend me some good literature, or point me in the direction where I should look/reed/study? I'm somewhat experienced game programmer, but I've never been into game design till now so any help will be great. I want to do this assignment as good as I can. As for deadline, it's not strictly set, but lets say I don't want it to take longer then few weeks, one month at worst case.

• How to implement a no-login authentication system

  - by mrwooster

  I am looking to build a very loose authentication system that can track a user and link submitted data/comments to a specific user. The submissions are essentially anonymous, but a user may want to edit his submission/comment at a later date. I want the experience to be as smooth as possible so do not want to ask users to sign up for an account and then login each time. There is no point as their submissions are not in their name and to another user browsing the site, there is no way of linking a submission to a specific user (think anonymous comments on a blog post or pastie). However, the user should have the ability to edit (at least in the short term) the content they have posted. The way I imagine doing this would be to place a unique identifier in a cookie on the users machine. This would enable me to link a submission to a user, and while that cookie remained on the users machine, I would allow them to edit their content. Of course, if the cookie is lost, or the user accesses the site from a different browser, then they would not be able to edit their content, but this is not really an issue, they can always resubmit a new piece of content. Is there a better way of doing this? How can I implement this so that the user can edit their data for the longest possible amount of time.

• sudo prompts for password over ssh

  - by Joe Watkins

  I have sudo set up for a shell script as follows on "hostname" (sudo -l output): (suser) NOPASSWD: /path/script* sudoers content is: myuser ALL=(suser) NOPASSWD: /path/script* this works fine, so I can run the following, logged in locally on hostname, without need for password: sudo -u suser /path/script however, when I use ssh (with keys set up, so no password require) to login and run, as follows: ssh hostname sudo -u suser /path/script I get prompted for a password, and when the password is entered I get: Sorry, user myuser is not allowed to execute '/path/script' as suser on hostname. Why? NB the following does not prompt for password at any point: $ ssh hostname $ sudo -u suser /path/script

• Can I block social share buttons with Privoxy?

  - by gojira

  A great many pages have these "Like", "Tweet", "G+1", "share" row of buttons all over the place and in each post in threads. Can I block these unwanted context with Privoxy? I am already using Privoxy and it blocks a lot of unwanted content, but still these "social" buttons are all over the place. I want to completely remove these buttons specifically by using Privoxy. I know that it is possible to block using AdBlock LITE and other software, but my question is specific to Privoxy (reason, I want one point to block all unwanted content and it needs to work on devices / softwares which do not have AdBlock LITE, therefore I use Privoxy). -- Software used: Privoxy 3.0.21 under Windows XP

• How do you structure your shared code so that it is "re-findable" for new developers?

  - by awmckinley

  I started working at my current job about 8 months ago, and its been one of the best experiences I've had as a young programmer. It's a small company, and both my co-developers are brilliant guys. One of the practices that they both have been encouraging is lots of code-reuse. Our code base is mainly C#, and we're using a centralized revision control system. The way the repository is currently structured, there is a single folder in which all shared class libraries are placed (along with unit tests for each library), and our revision control system allows for sharing or linking those libraries out to other projects. What I'm trying to understand at this point is how the current structure of the folder can be made more conducive for finding those libraries again. I've talked to the other developers about this, and they agree that it's gotten a little messy. I find that I am sometimes "reinventing the wheel" because I didn't realize that there was an existing piece of code that solved a particular problem. The issue is complicated further by the fact that we're sharing some code between ASP.NET MVC2, WinForms, and Windows CE projects, and sharing code between applications built against multiple versions of .NET. How do other people approach this? Is the answer in naming the libraries in a certain way or is it preferable to invest in some code-search software? Is the answer in doc comments? Should we be sharing libraries at all or should we simply branch the class libraries for re-use? Thanks for any and all help!

• What is the best free service to host images and mp3 files?

  - by Edward Tanguay

  I am making an educational social software silverlight application. I would like users to be able to point the application to a URL with text, images, and audio files which they have created. Many users will not have their own website to do this, so we are looking for a free service they can use to upload, and manage their own text/image/audio content. What is the best free service for non-technical users to upload and make available text, images and audio? For instance, sites.google.com allows you to upload pictures and access them via http so that would work, but that is more about making a website. For this purpose we just need the ability to upload files, without the website creation tools.

• Why do partially failed/failing switches fail to pass DHCP?

  - by David Mackintosh

  I've noticed this several times: a switch starts to behave oddly. Usually if the switch doesn't fail outright, what tends to get noticed is that DHCP doesn't work. We had a Linksys SRW-224P fail today. Systems which were still connected worked properly, until it came time to renew their DHCP lease. Once the lease expired, they stopped working, but up until then we couldn't detect a failure. This includes PoE VoIP phones -- they work fine until their lease is up, at which point they're done. I've noticed this on the above-mentioned Linksys, three varieties of 3Com, and possibly half a dozen dumb switches. What is it about DHCP that makes it sensitive to failing switches?

• Simplest way to shrink transaction log files on a mirrored production database

  - by MGOwen

  What's the simplest way to shrink transaction log file on a mirrored production database? I have to, as my disk space is running out. I will make a full database backup before I do this, so I don't need to keep anything from the transaction log (right? I have daily full database backup, probably never need point-in-time restore, though I'll keep the option open if I can - that's all the .ldf is really for, correct?). (Hope this isn't an exact duplicate, I read a lot of questions but couldn't find this exact scenario elsewhere).

• Do most "normal" people use metro or desktop in Windows 8

  - by ihateapps

  Just curious since I don't fit the definition of a "normal" computer user nor have my friends or relatives upgraded to Windows 8 yet. Are most people in the "wild" (i.e. the "guy in starbucks" or "your friend who works as an auto tech". not you since you are on SU) using metro apps regularly to the point where the desktop is pointless or are they sticking with the desktop? I've gotten mixed statistics from Google. I'm asking for your personal anecdotal opinion based on what you notice in the wild.

• How can i install ubuntu on my ntfs hdd without formatting?

  - by Ridvan Coban

  My hdd is just one partition in ntfs (500gb) and 430 gb is used by my photos/movies/music etc which i never will want to lose. Actually i installed ubuntu on a usb flash drive (using it right now) but it is too slow that way. But my problem is : My computer is damaged ( maybe chipset or but not sure) and none of the windows versions (xp,vista,7) works on my pc. I get blue screen error as soon as windows startup logo shows. But ubuntu just works flawless. That means i cannot use wubi. I wanted to shrink my hdd without losing data (which can be done in windows) but found nothing about that on ubuntu forums. Is this possible? Or install ubuntu on my ntfs filesystem? Note : I don't have chance to backup 400 gbs of data. Sorry for my question if it's written a bit compex. I hope you get the point and someone has an idea ;)

• A website hosted on the 1.0.0.0/8 subnet, somewhere on the Internet?

  - by Dave Markle

  Background I'm attempting to demonstrate, using a real-world example, of why someone would not want to configure their internal network on the 1.0.0.0/8 subnet. Obviously it's because this is not designated as private address space. As of 2010, ARIN has apparently allocated 1.0.0.0/8 to APNIC (the Asia-Pacific NIC), who seems to have begun assigning addresses in that subnet, though not in 1.1.0.0/16, 1.0.0.0/16, and others (because these addresses are so polluted by bad network configurations all around the Internet). My Question My question is this: I'd like to find a website that responds on this subnet somewhere and use it as a counter-example, demonstrating to a non-technical user its inaccessibility from an internal network configured on 1.0.0.0/8. Other than writing a program to sniff all ~16 million hosts, looking for a response on port 80, does anyone know of a directory I can use, or even better yet, does anyone know of a site that's configured on this subnet? WHOIS seems to be too general of a search for me at this point...

• Installing Xubuntu alongside with UEFI

  - by Geo

  For the past week and a half I have been trying to figure out how to install Xubuntu 13.10 alongside the Windows 7 install I have on my laptop (ASUS X501A with UEFI) and I'm pretty much at my wit's end. Could someone point me to set of thorough instructions on installing Xubuntu (or any of the Ubuntu derivatives) on a HDD under UEFI alongside Windows 7 64-bit Home Premium? Preferably one that also covers GRUB/bootloader problems that come afterwards. A few additional details: Motherboard does have UEFI. I've disabled Secure Boot and Fast Boot. Launch CSM is enabled and the platform keys are not installed (these settings allow me to at least boot Windows 7). I set the HDD's partition table to GPT through GParted before I installed Windows. I'm installing from a bootable USB that has been created through a tool called Rufus with the GPT partition scheme for UEFI computers option, otherwise I've left it at default. I am able to boot into Xubuntu in UEFI mode, but I'd much rather be able to see the option: Install Xubuntu Alongside Windows 7 (or however it's phrased), Xubuntu seems to be unable to recognize that Windows 7 is installed. I do have access to a bootable USB stick containing GParted though Xubuntu seems to come preinstalled with it. If there's anything else that might be of help, please let me know.
