• Access a windows dynamic hard drive through a virtual machine on ubuntu?

  - by Enigma

  I have a Windows 7 OS and am thinking about transitioning to a dual boot set up with Ubuntu 12.04. From what I recall, it is not possible to natively access Dynamic Windows Partitions in a Linux OS. My thought is that it might be possible to have a virtual machine (running windows) installed within Ubuntu access the physical dynamic drive. The problem comes to whether VMWare can access the physical disk "high enough" to be able to mount it within the windows virtual machine as a native device or if it gets passed through from the native Linux OS. This is really the only thing holding me back from switching to a dual-boot set up as the dynamic disk is made up of 4 or 5 hard drives and I would very much like access to the data on both OS's. Alternatively, is there another solution for combining multiple physical hard drives into one virtual hard drive that would be readable on both OS's?

• Locale number formatting issue windows 2008

  - by kris

  On a project we have multiple servers running windows 2008. The servers are using the Russian locale. We have several programs that use floating point numbers but the fractional part of the number on SOME servers is getting truncated. Through the regional settings each machine has: Locale: Russian Current Location: United States Decimal Symbol: . (period) I've tried distributing the changes through "Copy Settings" and even though the procedure works it seems like the settings aren't actually being propagated. So next I went into the registry. There is a key called "sDecimal" and in all cases on all servers the value in the key is '.' There is no difference that I can find between the servers that DO have correct decimal formatting and DO NOT. Any advice on where I can look for a problem like this?

• Ubuntu/Linux version recommendation for HP dv6 3122TX?

  - by sanjayav

  I purchased a HP dv6 3122TX recently and after installing Ubuntu 10.10 64 bit I ran into multiple issues like, The wireless driver is not supported by Uubntu. (1) [The driver is RaLink RT3090 ] The ethernet stopped working sometimes for no reason [The driver is Realtek RTL8111/8168B ] "Corrupted low memory at ..." issue which is described as a kernel bug in Ubuntu support forums. (It started to take me to a terminal instead of the GUI and couldn't start x server after that) As I'm not an expert Ubuntu user I got fed up of all these issue and got back to Windows 7. But I need an Ubuntu installation up and running for my development work. What are your suggestions about a reasonable Ubuntu version that I should try? Or a different Linux variation? Should I stick to a 32-bit version? It'd be great anyone can give some advice on this issue.

• How do I recover an accidentaly closed Opera window?

  - by Kostas

  Hello there and thanks for all the help! I accidentaly closed a window with multiple tabs in Opera. There was another window with a couple of tabs running. I have closed and restarted Opera in the hope it will retrieve the windows at startup (it usually asks if I want to continue from last time). Is there a way I can retrieve my closed window with all the tabs? I cannot see them in the history either, probably because When I switched-on my PC the Internet connection was down and the pages didn't load :-/

• Cocos-2D asteroids style movement (iOS)

  - by bwheeler96

  So I have a CCSprite subclass, well call this Spaceship. Spaceship needs to move on a loop, until I say othersise by calling a method. The method should look something like - (void)moveForeverAtVelocity { // method logic } The class Spaceship has two relevant iVars, resetPosition and targetPosition, the target is where we are headed, the reset is where we set to when we've hit our target. If they are both off-screen this creates a permanent looping effect. So for the logic, I have tried several things, such as CCMoveTo *move = [CCMoveTo actionWithDuration:2 position:ccp(100, 100)]; CCCallBlockN *repeat = [CCCallBlockN actionWithBlock: ^(CCNode *node) { [self moveForeverAtVelocity]; }]; [self runAction:[CCSequence actions: move, repeat, nil]]; self.position = self.resetPosition; recursively calling the moveForeverAtVelocity method. This is psuedo-code, so its not perfect. I have hard-coded some of the values for the sake of simplicity. Enough garble: The problem I am having, how can I make a method that loops forever, but can be called and reset at will. I'm running into issues with creating multiple instances of this method. If you can offer any assistance with creating this effect, that would be appreciated.

• Accurate way to check latency between Server ?

  - by Rick

  Hi, First of all, I hope my post are is posted in the right section . Below are something i got confused hope you one can help. My business partner 's IP server are in: Sanjose, CA , and I am looking for a datacenter which give the least latency to that IP. I found 2 . 1st datcenter is in San Francisco, CA . 2nd data center is in Newyork. Then I do the ping from each datacenter to the my partner's IP. 1st datcenter's result: 75ms 2nd datacenter's result: 2ms I 've done multiple time, 2nd datacenter always give better result. Now my question is: Isn't the 1st datacenter suppose to give better result, since their location are closer ? How come the result produce different, what is the accurate way to check latency ? Thanks

• Javascript storing data

  - by user985482

  Hi I am a beginner web developer and am trying to build the interface of a simple e-commerce site as a personal project.The site has multiple pages with checkboxes.When someone checks an element it retrives the price of the element and stores it in a variable.But when I go to the next page and click on new checkboxes products the variable automaticly resets to its original state.How can I save the value of that variable in Javascript? This is the code I've writen using sessionStorage but it still dosen't work when I move to next page the value is reseted. How can I wright this code so that i dosen't reset on each page change.All pages on my website use the same script. $(document).ready(function(){ var total = 0; $('input.check').click(function(){ if($(this).attr('checked')){ var check = parseInt($(this).parent().children('span').text().substr(1 , 3)); total+=check; sessionStorage.var_name=0 + total; alert(sessionStorage.var_name); }else{ var uncheck = parseInt($(this).parent().children('span').text().substr(1 , 3)); total-=uncheck; } })

• OSB, Service Callouts and OQL

  - by Sabha

  Oracle Fusion Middleware customers use Oracle Service Bus (OSB) for virtualizing Service endpoints and implementing stateless service orchestrations. Behind the performance and speed of OSB, there are a couple of key design implementations that can affect application performance and behavior under heavy load. One of the heavily used feature in OSB is the Service Callout pipeline action for message enrichment and invoking multiple services as part of one single orchestration. Overuse of this feature, without understanding its internal implementation, can lead to serious problems. This series will delve into OSB internals, the problem associated with usage of Service Callout under high loads, diagnosing it via thread dump and heap dump analysis using tools like ThreadLogic and OQL (Object Query Language) and resolving it. The first section in the series will mainly cover the threading model used internally by OSB for implementing Route Vs. Service Callouts. The second section of the "OSB, Service Callouts and OQL" blog posting will delve into thread dump analysis of OSB server and detecting threading issues relating to Service Callout and using Heap Dump and OQL to identify the related Proxies and Business services involved. The final section of the series will focus on the corrective action to avoid Service Callout related OSB serer hangs. Before we dive into the solution, we need to briefly discus about Work Managers in WLS. Please refer to the blog posting for more details.

• Upgrading to 12.10 on an external hard drive

  - by Tom Childers

  I did some googling on this and didn't find anything specific for my situation. I currently have 12.04 installed on an external USB hard drive. It's working great. I want to upgrade it to 12.10. My bandwidth is very limited so I have a friend who will download 12.10 for me and put it on a flash stik. Then I can upgrade without having to do the download myself. Which particular version of the 12.10 download file(s) should I get? Are there alternate 12.10 downloads that have all the packages? How do I set it up so when I upgrade 12.04 I can specify that it look in some local repository for the 12.10 files? Can I just dump the 12.10 files in some local directory? Or do I have do go thru some complex commands to create a local repository? I'm pretty new to Linux so a long process of complex terminal commands will probably be a show stopper for me. Remember that my 12.04 install resides on an external hard drive. And I have a laptop with multiple USB ports. Thanks! Advait

• Grouping extensions in Asterisk

  - by Matt H

  We have an asterisk based phone system with multiple clients connected to it. At the moment, all the extension numbers fall in the range 100 - 9999. But, now we have an issue where a particular customer wants to come onto our service and insists on keeping their existing extension list. Is there a way of having extensions 700 for one customer, and also the same number range to another customer. But yet having them belong to a different group? I see there is a concept of groups in asterisk but none of them seem to provide a solution to this.

• Pages partially load on rapid refresh

  - by user101570

  I recently set up a VPS slice with 256MB to run a LAMP stack (Ubuntu 11.04, Apache2, Mysql, PHP5). So far I'm only running a simple Wordpress site on an IP-based virtual host I set up. The performance is excellent, but I've noticed that if I send multiple HTTP requests from the same IP in a short time period, only partial pages are rendered. Then if I wait a bit and refresh the page, the entire page loads again. I noticed this behaviour when accessing the site from two browsers from my office desktop, but it also presents itself if I quickly navigate the site from a single browser (any browser). I'm guessing this is an Apache phenomenon, as the pages are rendered correctly except under the conditions above, but perhaps I'm wrong here. Could it be my hosting company with some kind of DOS protection in place? As a relative Linux/server noob, I'd really appreciate any insight into what settings in Apache could explain this behaviour, and how I might go about changing it.

• Throwing and catching exceptions in the same function/method

  - by usr

  I've written a function that asks a user for input until user enters a positive integer (a natural number). Somebody said I shouldn't throw and catch exceptions in my function and should let the caller of my function handle them. I wonder what other developers think about this. I'm also probably misusing exceptions in the function. Here's the code in Java: private static int sideInput() { int side = 0; String input; Scanner scanner = new Scanner(System.in); do { System.out.print("Side length: "); input = scanner.nextLine(); try { side = Integer.parseInt(input); if (side <= 0) { // probably a misuse of exceptions throw new NumberFormatException(); } } catch (NumberFormatException numFormExc) { System.out.println("Invalid input. Enter a natural number."); } } while (side <= 0); return side; } I'm interested in two things: Should I let the caller worry about exceptions? The point of the function is that it nags the user until the user enters a natural number. Is the point of the function bad? I'm not talking about UI (user not being able to get out of the loop without proper input), but about looped input with exceptions handled. Would you say the throw statement (in this case) is a misuse of exceptions? I could easily create a flag for checking validity of the number and output the warning message based on that flag. But that would add more lines to the code and I think it's perfectly readable as it is. The thing is I often write a separate input function. If user has to input a number multiple times, I create a separate function for input that handles all formatting exceptions and limitations.

• Solutions for iOS collaborative sync (iCloud CoreData, CouchDB)?

  - by mluisbrown

  I'm developing an iOS app where one of the features will be allowing users to share and collaborate on data (e.g. lists). From everything I've read and based on the way that iCloud CoreData sync works I assume that it would not be a good fit for the following reasons, but I wanted to make sure I wasn't missing anything, as I'd prefer not to use a 3rd party syncing solution if at all possible: iCloud sync of any kind (CoreData, Document or Key / Value pairs) can only ever be between devices that use the same iCloud account, so it's designed for a single user syncing data over multiple devices. Any kind of collaborative sync (several people editing the same document / list) simultaneously would be limited to everyone have the same iCloud account. Cases of people sharing the same iCloud account is usually limited to, for example, husband and wife or similar close relationships for a small number of people. iCloud Core Data sync is for ensuring that each sync'd device has the same data. It doesn't seem to allow syncing just a subset of the data, so scenarios in which each user has their own documents and is only sharing / collaborating on a subset of them are not supported. And I'm not even mentioning the well document problems with iCloud CoreData syncing which may or may not have been resolved with iOS 7. Given the above, it would seem that CouchDB (with TouchDB) would be a better option, as it seems to support everything I need. What other options are there that people can recommend?

• How can I create a bootable DVD iso from a USB drive?

  - by Kiada

  There seems to be a lot of questions / answers about doing the reverse, but not as much info for USB - DVD. Problem I created a bootable USB drive using YUMI. The USB drive is working great, and contains the following: Linux Mint 13 Linux Mint Debian Debian 6 Ubuntu 12.04.1 Fedora 17 A bit of a mix of DVD and Live versions. I have a spindle of DVD+R DL blank DVD's. I would like to create a bootable .iso from this USB drive so I can burn multiple copies of it to pass around to friends! I've created an iso using Folder2ISO, but it coastered my DVD because it wasn't bootable. I don't really want to waste a whole spindle! How would you go about doing such a thing?

• refresh windows network performance counters in command line

  - by michalv82

  I am testing a USB device connected to a windows PC. When the device is connected then windows has another network interface going through the device. I need to get the bytes transffered for that specific interface, basically I need the data shown in the networking tab in the task manager for my interface adapter. I found this question which helped to get this info: ms windows network activity bytes send and receive in command line However I have a problem when I run multiple tests - each time I disconnect and connect the device there's another line for the interface, like below. In the task manager networking tab I only see one record for my interface but I don't know how I can know from command line which is the lastest and current instance (it's not like the first line or last line is always the current interface, I noticed it's not consistent): wmic path Win32_PerfRawData_Tcpip_NetworkInterface Get Name,PacketsReceivedPerSec,PacketsSentPerSec,BytesReceivedPersec,BytesSentPersec BytesReceivedPersec BytesSentPersec Name PacketsReceivedPersec PacketsSentPersec 422666370 6317989292 Intel[R] 82579LM Gigabit Network Connection 2715169 8109643 49150 375973 My USB Device 432 568 0 0 My USB Device _2 0 0 0 0 My USB Device _3 0 0 0 0 My USB Device _6 0 0 0 0 Local Area Connection* 9 0 0

• How to manage large number of desktop VMs?

  - by symcbean

  I'm looking at the feasibility of providing remote access to multiple virtual machines. The VMs themselves will provide user desktops. To make best use of the available resources, I'd like the VMs to hibernate when the user disconnects. Which implies being able to start them up when a user connects. Ideally each user would 'own' a VM image - but if not then I'd require that the session was terminated. Obviously this would require the remote access protocol to be tied into the VM management. Is there anything out there to provide such functionality? (extra credit for open protocols! ;)

• View the Time & Date in Chrome When Hiding Your Taskbar

  - by Asian Angel

  Do you prefer keeping your Taskbar hidden but still need to keep watch on what time it is? Now you can keep track of the time without the Taskbar using the Date Today extension for Google Chrome. A Look at Date Today with Different Themes This extension does one thing and does it well…it provides you with an “active icon” clock that will let you view the time and date in two fashions. The first is by hovering your mouse over the “Toolbar Clock Button”… And the second is by clicking on the “Toolbar Clock Button” to view an enlarged version. Here you can see the extension in use with five different themes to get an idea of how it might look with the theme that you are currently using. It does stand out very nicely with brighter or darker colored themes. Conclusion While this extension is obviously not for everyone it will make a nice (and useful) addition to Chrome for those who prefer keeping their Taskbar hidden.

• Two components offering the same functionality, required by different dependencies

  - by kander

  I'm building an application in PHP, using Zend Framework 1 and Doctrine2 as the ORM layer. All is going well. Now, I happened to notice that both ZF1 and Doctrine2 come with, and rely on, their own caching implementation. I've evaluated both, and while each has its own pro's and cons, neither of them stand out as superior to the other for my simple needs. Both libraries also seem to be written against their respective interfaces, not their implementations. Reasons why I feel this is an issue is that during the bootstrapping of my application, I have to configure two caching drivers - each with its own syntax. A mismatch is easily created this way, and it feels inefficient to set up two connections to the caching backend because of this. I'm trying to determine what the best way forward is, and would welcome any insights you may be able to offer. What I've thought up so far are four options: Do nothing, accept that two classes offering caching functionality are present. Create a Facade class to stick Zend's interface onto Doctrine's caching implementation. Option 2, the other way around - create a Facade to map Doctrine's interface on a Zend Framework backend. Use multiple-interface-inheritance to create one interface to rule them all, and pray that there aren't any overlaps (ie: if both have a "save" method, they'll need to accept params in the same order due to PHP's lack of proper polymorphism). What option is best, or is there a "None of the above" variant that I'm not aware of?

• Alternate Client for Cisco Unified Personal Communicator protocol

  - by Jason M

  At work we have an in-house chat system using CUPC. Does anyone else out there use this? There are a few things I do not like about this client: Where's the chat log? If I close the window, I have no way of getting my conversation back. Tabbed interface? That would be nice. I hate having multiple chat windows up, having to arrange them around my desktop as more people start talking to me. I don't like that I have to use this one-off application for particular this protocol when other chat clients will handle 99% of the other protocols I use. Tell me: Is the protocol an open standard for which other applications have support? (pidgin, adium, digsby, etc.) If not, can I overcome these issues from within CUPC? Perhaps there are newer versions of the client that overcome these issues.

• How to download big file with chrome on Mac OSX?

  - by Eye of Hell

  If I try to download a big file on unstable connection/server (XCode 4) Google chrome simply "stops" downloading on first network error so I have a first 1-2-3 gigabytes of file and chrome thinks that download is finished. Unfortunately, I need to download an entire file, so I need a more advanced download tool like a wget. But there comes a problem: most URL's currently on the web is not a direct URL but multiple "redicrect" pages that utilize complex javascript in order to generate next url and redirect browser to it. Chrome handles such things ok, but if I try to supply such URL to wget it will download some "intermediate" page as a file - not a file itself but an HTML page with complex redirect javascript. is it any way to get a direct URL from chrome or to somehow discover it so I can use it with wget? Maybe it's some avanced download manager integrated in chrome that I just need to install? I use MacOS X 10.6.6 and latest Google chrome.

• App to slice'n'dice video, specifically remove chunks, on a Mac?

  - by Phillip Oldham

  I have a couple of collections of DVD Box-Sets I've ripped to my mac. Now I'd like to sweeten the viewing experience by removing the title sequences and credits so that viewing doesn't mean I have to keep reaching for the remote to skip 30 seconds of annoying music (think watching multiple episodes of Family Guy). If I can find an app that will let me do this reasonably quickly manually that would be great, but it would be perfect if I could dump a load of commands into a file and have everything trimmed while the mac is "inactive". I'm thinking that if I can specify chunks of time to remove from the original file that would be perfect. I had a quick look at importing into iMovie to do it manually and gave up at the "Processing Thumbnails" stage as it said it would be a couple of hours to produce them for a 45min mp4 file, which I can understand at 25fps but I'm not willing to wait, especially when I've got over a week's worth of files. Any suggestions?
