  • Opportunity Nokia's

    - by Andrew Clarke
    Nokia’s alliance with Microsoft is likely to be good news for anyone using Microsoft technologies, and particularly for .NET developers. Before the announcement, the future wasn’t looking so bright for the ‘mobile’ version of Windows, Windows Phone. Microsoft currently has only 3.1% of the Smartphone market, even though it has been involved in it for longer than its main rivals. Windows Phone has now got the basics right, but that is hardly sufficient by itself to change its predicament significantly. With Nokia's help, it is possible. Despite the promise of multi-tasking for third party apps, integration with Microsoft platforms such as Xbox and Office, direct integration of Twitter support, and the introduction of IE 9 “later this year”, there have been frustratingly few signs of urgency on Microsoft’s part in improving the Windows Phone  product. Until this happens, there seems little prospect of reward for third-party developers brave enough to support the platform with applications. This is puzzling when one sees how well SQL Server and Microsoft’s other server technologies have thrived in recent years, under good leadership from a management that understands the technology. The same just hasn’t been true for some of the consumer products. In consequence, iPads and Android tablets have already exposed diehard Windows users, for the first time, to an alternative GUI for consumer Tablet PCs, and the comparisons aren’t always in Windows’ favour. Nokia’s problem is obvious: Android’s meteoric rise. Android now has 33% of the worldwide market for smartphones, while the market share of Nokia’s Symbian has dropped from 44% to 31%. As details of the agreement emerge, it would seem that Nokia will bring a great deal of expertise, such as imaging and Nokia Maps, to Windows Phone that should make it more competitive. It is wrong to assume that Nokia’s decline will continue: the shock of Android’s sudden rise could be enough to sting them back to their previous form, and they have Microsoft’s huge resources and marketing clout to help them. For the sake of the whole Windows stack, I really hope the alliance succeeds.

  • Is MediaTemple's (gs) really worth the hassle? [closed]

    - by Andrew
    I have been hosting my sites with Dreamhost for a while, and although none of them are high-trafic atm, I am going to a launch a Rails app this summer and a couple of other stuff, so I need a serious host. Since my plan ends in a couple of days, I have been looking at alternatives, and because MT has such a good reputation in the webdesign world, I have been seriously considering paying the ridiculous 20$/month for its shared hosting services. That was until I actually read some reviews of it, most of which indicated it is slow and overpriced. So now I'm wondering whether switching over to (gs) would really be a good idea, or if I would be better off paying less money for something like a Site5 or Hostgator shared hosting plan. What is your experience with MT, and particularly their Grid Service? Do you think I should even switch to (gs) in the first place, or should I choose something else from its competitors?

  • Are there any tools for testing drag & drop Windows desktop applications?

    - by Andrew
    I need to develop a Windows desktop application (win32 API) which will use drag & drop extensively in many formats, including my own. I need to test it, for example, with CF_TEXT dragging, CF_RTF, CF_DIB, CF_METAFILEPICT, and many others. The tool needs to have the following features: Displaying the content of DataObject dragged into it with all available format viewers. Allows preparation of a few samples of different clipboard formats together in a single DataObject, ready for dragging into my app. Allows including my own format names into the formats list of the testing tool.

  • Cannot install gnome extensions from gnome site. No switch appearing in firefox or chrome

    - by Andrew James Adams
    I have installed ubuntu 12.04, and installed gnome3 on my system. I am attempting to download the user theme extensions from extensions.gnome.org, but I can't see this "switch" everyone's talking about. I've tried both chromium and firefox browsers on the site. I found a similar subject here at askUbuntu. I followed the directions but I got a warning about gnome common dependencies. I installed gnome-extensions-common without an error but I still cannot install user-themes, and I can't find the mysterious "switch". Any ideas? Thanks in advance.

  • Canon MP495 Scanner not working

    - by Andrew
    Running 12.04, installed and updated latest drivers for MP495 but nothing stil. latest drivers provided here: https://code.launchpad.net/~michael-gruz/+archive/canon-trunk/+packages Followed this guide to the letter: http://ubuntuforums.org/showthread.php?t=1602839&page=11 Xsane and simple scan do not work. I have tried various other programs and have nothing... People are saying it works well with 11.10, so I don't know what the deal is with 12.04. Any help would be greatly appreciated as I need this printer for my out-of-home business, and I really don't want to switch back windows just for a freaking scanner to function. Why don't these companies realise ubuntu users need to print things too?!

  • Good text editor for Ruby on Rails programming?

    - by Andrew
    I'm trying to find a text editor that I can use for doing Ruby on Rails development. I have been using TextMate on my Mac and would love to find something that even comes close to that experience. My Ubuntu laptop is a little old, and doesn't have a lot of memory, so I need something lightweight. I don't need/want a bloated IDE because the performance on my slow laptop would be terrible. It would be nice if this text editor had: Syntax highlighting A project/file browser view to be able to open files in my project Keyboard shortcuts (don't need them as much)

  • Ubuntu boots up maintenance shell?

    - by Andrew
    Any time I try to start up my computer it goes to a screen titled GNU GRUB version 1.99-12ubuntu5 I can then choose from 5 different options. If I try to just boot Ubuntu, with Linux 3.0.0-20-generic it then goes to a screen saying: mountall: /lib/x86_64-linux-gnu/libc.so.6: version 'GLIBC_2.14' not found (required by /lib/libply.so.2) General error mounting filesystems. A maintenance shell will now be started. CONTROL-D will terminate this shell and reboot the system. root@Brown126:~# Control-D just brings me back to the first screen. And nothing works in recovery mode. How can I fix this?

  • make my Ubuntu 12.04 laptop visible on the network

    - by Andrew Boyd
    I'm ecstatically happy with my 12.04 on my laptop after loading it over my MS Vista... but there's just one thing, one little fly in the ointment.... While I can view our 2 Terabyte, shared hard-drive in the lounge (and copy files back and forth) I can't see my PC (when I boot up in Ubuntu 12.04) nor the Lubuntu computer connected to the TV (for movies, Youtube etc). Printing to the HP office jet on the PC doesnt work over the network either. Have had one dubious flirtation with Samba, which seems to be the only thing I've found that will 'work', however halfway through that "installation" everything just ground to a halt, the directions began to stop making sense... I was working from this page. Our Network consists of the following: Our Internet service is wirelessly sent to us from our provider to our dish on a pole. It comes into the house via an ethernet cable. We split it there to a phone, and to 6 other destinations (bedrooms, computers, and to another splitter in the lounge which has a wifi antennae and 4 ethernet ports). one port goes to the Lubuntu OS PC which is connected to the TV the second port goes to the 2 Terabyte harddrive (MS powered 'Mybooklive') (the other two are empty) My Ubuntu 12.04 laptop connects wirelessly to this splitter in the lounge. I know just enough about computers to get myself into an awful mess without too much trouble We usually can view friends' laptops when they get on our network (as they are invariably MS OS's) Our flatmate, who introduced us to Linux's computer is also invisible How can we make our Linux OS based computers visible on the network and share files and printing?

  • Absolute beginner to app developement [closed]

    - by Andrew Johnston
    I have two app ideas that I am trying to build. I have started at the Facebook developement pages and done the Heroku/Git thing. However, I have absolutely no idea of what I am doing. When they say on the developer page: follow these quick easy steps Are they assuming that they are talking to a programmer/developer? I believe my apps have huge potential but I don't want to disclose my ideas. Any advice? I also would like to know how does one make money from Facebook applications?

  • Hadoop and Object Reuse, Why?

    - by Andrew White
    In Hadoop, objects passed to reducers are reused. This is extremely surprising and hard to track down if you're not expecting it. Furthermore, the original tracker for this "feature" doesn't offer any evidence that this change actually improved performance (unless I missed it). It would speed up the system substantially if we reused the keys and values [...] but I think it is worth doing. This seems completely counter to this very popular answer. Is there some credence to the Hadoop developer's claim? Is there something "special" about Hadoop that would invalidate the notion of object creation being cheap?

  • Installing gdm on headless Server Edition

    - by Andrew Koester
    I have Ubuntu Server running on a headless box, which is right now, almost entirely doing only software RAID and feels a little underused. I'd like to get into using Ubuntu as a desktop a little more. What do I need to do (install/etc.) to get Gnome while keeping the box itself headless? I'm not sure which packages to install or which steps to take. I figure I'll just use X over the network (Xming or the like) but something like NX might work.

  • Was it necessary to build this site in ASP.NET ?

    - by Andrew M
    From what I'm told, the whole StackOverflow/StackExchange 'stack' is based on Microsoft's ASP.NET. SO and the SE sites are probably the most complex that I visit on a regular basis. There's a lot going on in every page - lots of different boxes, pulling data from different places and changing dynamically and responding to user interaction. And the sites work very smoothly, despite the high traffic. My question is, could this have been achieved using a different platform/framework? Does ASP.NET lend itself to more complex projects where other web frameworks would strain and falter? Or is the choice pretty incidental?

  • How to play .mp4 movies?

    - by Andrew
    I have a .mp4 movie (it's an .mp4 file, and the "video codec" is Xvid, and the "audio codec" is mp3) that I want to play, but when I try to open it in MPlayer, it says "The steam is encrypted and decryption is not supported." I tried to apply the answer from this question and this wiki page, but neither worked. Any suggestions? The file came from an [apparently] less than reputable site, which I guess I can't link to. :( I've tried: sudo apt-get install ubuntu-restricted-extras sudo apt-get install libdvdread4 sudo /usr/share/doc/libdvdread4/install-css.sh sudo apt-get install gstreamer0.10-ffmpeg sudo apt-get install w64codecs sudo apt-get update

  • How to refactor and improve this XNA mouse input code?

    - by Andrew Price
    Currently I have something like this: public bool IsLeftMouseButtonDown() { return currentMouseState.LeftButton == ButtonState.Pressed && previousMouseSate.LeftButton == ButtonState.Pressed; } public bool IsLeftMouseButtonPressed() { return currentMouseState.LeftButton == ButtonState.Pressed && previousMouseSate.LeftButton == ButtonState.Released; } public bool IsLeftMouseButtonUp() { return currentMouseState.LeftButton == ButtonState.Released && previousMouseSate.LeftButton == ButtonState.Released; } public bool IsLeftMouseButtonReleased() { return currentMouseState.LeftButton == ButtonState.Released && previousMouseSate.LeftButton == ButtonState.Pressed; } This is fine. In fact, I kind of like it. However, I'd hate to have to repeat this same code five times (for right, middle, X1, X2). Is there any way to pass in the button I want to the function so I could have something like this? public bool IsMouseButtonDown(MouseButton button) { return currentMouseState.IsPressed(button) && previousMouseState.IsPressed(button); } public bool IsMouseButtonPressed(MouseButton button) { return currentMouseState.IsPressed(button) && !previousMouseState.IsPressed(button); } public bool IsMouseButtonUp(MouseButton button) { return !currentMouseState.IsPressed(button) && previousMouseState.IsPressed(button); } public bool IsMouseButtonReleased(MouseButton button) { return !currentMouseState.IsPressed(button) && previousMouseState.IsPressed(button); } I suppose I could create some custom enumeration and switch through it in each function, but I'd like to first see if there is a built-in solution or a better way.. Thanks!

  • handling a GET error properly

    - by Andrew Heath
    I have a website that takes two primary get strings: ?type=GAME&id=SomeGameID ?type=SCENARIO&id=SomeScenarioID for reasons unknown, I have recently begun receiving requests for erroneous get strings from both Yandex and Baidu. They are always in the form of: ?type=GAME&id=SomeScenarioID None of my users are triggering these errors, so I am (sort of) confident that this is not due to an HTML template error somewhere on my part. There is also no HTTP_REFER showing up in the $_SERVER array, so I'm guessing these are direct requests from bad dbase data on their part. I see two options for dealing with these bad requests, and would like to know which is recommended... or if there are other, better options I have not thought of: simply 404 the request, since it is incorrect redirect the request to ?type=SCENARIO&id=SomeScenarioID because the scenario IDs are always valid, the breakage is due to asking for the wrong type.

  • Insanity joining Server 12.04 to Windows AD

    - by Andrew Stebenne
    I've seen lots of stuff about this error on the internet, but had no luck implementing a solution. I'm trying to use Likewise-Open to join an Ubuntu Server 12.04 machine to a Windows Active Dicrectory domain controller and having absolutely no luck. I run: sudo domainjoin-cli join my.domain.gob ADMINISTRATOR and get back (after putting in the admin password): Error: DNS_ERROR_BAD_PACKET [code 0x0000251e] A bad packet was recieved from a DNS server. Potentially the requested address does not exist. I have heard that WAD insists on being your only nameserver, and in attempts to make that work, I've tried editing /etc/resolv.conf and /etc/network/interfaces but none of that has worked either. Ideas?

  • How do I account for changed or forgotten tasks in an estimate?

    - by Andrew
    To handle task-level estimates and time reporting, I have been using (roughly) the technique that Steve McConnell describes in Chapter 10 of Software Estimation. Specifically, when the time comes for me to create task-level estimates (right before coding begins on a project), I determine the tasks at a fairly granular level so that, whenever possible, I have no tasks with a single-point, 50%-confidence estimate greater than four hours. That way, the task estimation process helps with constructing the software while helping me not to forget tasks during estimation. I come up with a range of hours possible for each task also, and using the statistical calculations that McConnell describes along with my historical accuracy data, I can generate estimates at other confidence levels when desired. I feel like this method has been working fairly well for me. We are required to put tasks and their estimates into TFS for tracking, so I use the estimates at the percentage of confidence I am told to use. I am unsure, however, what to do when I do forget a task, or I end up needing to do work that does not neatly fall within one of the tasks I estimated. Of course, trying to avoid this situation is best, but how do I account for forgotten/changed tasks? I want to have the best historical data I can to help me with future estimates, but right now, I basically am just calculating whether I made the 50%-confidence estimate and whether I made it inside the ranged estimate. I'll be happy to clarify what I'm asking if needed -- let me know what is unclear.

  • Is there a tool that allows site users to schedule meetings with each other? [closed]

    - by Andrew Min
    I'm the webmaster for a debate team, and we're trying to find a tool that allows us to have multiple team members say when they're available and see who else is available during those timeslots for one-on-one practice rounds. I suppose we could use something like Doodle, but that would involve recreating the Doodle every week. There are many scheduling tools available, but they're usually built so that you can sign up to meet with a specific individual (think a doctor or a professor's office hours), whereas you could be paired with ANY individual.

  • An alternative to a video codec for storing motion changes [on hold]

    - by Andrew Simpson
    I have a 3 dimensional byte array. The 3-d array represents a jpeg image. Each channel/array represents part of the RGB spectrum. I am not interested in retaining black pixels. A black pixel is represented by this atypical arrangement: myarray[0,0,0] =0; myarray[0,0,1] =0; myarray[0,0,2] =0; So, I have flattened this 3d array out to a 1d array by doing this byte[] AFlatArray = new byte[width x height x 3] and then assigning values respective to the coordinate. But like I said I do not want black pixels. So this array has to only contain color pixels with the x,y coordinate. The result I want is to re-represent the image from the i dimension byte array that only contains non-black pixels. How do I do that? It looks like I have to store black pixels as well because of the xy coordinate system. I have tried writing to a binary file but the size of that file is greater than the jpeg file as the jpeg file is compressed. I am using c#.

  • Dealing with state problems in functional programming

    - by Andrew Martin
    I've learned how to program primarily from an OOP standpoint (like most of us, I'm sure), but I've spent a lot of time trying to learn how to solve problems the functional way. I have a good grasp on how to solve calculational problems with FP, but when it comes to more complicated problems I always find myself reverting to needing mutable objects. For example, if I'm writing a particle simulator, I will want particle "objects" with a mutable position to update. How are inherently "stateful" problems typically solved using functional programming techniques?

  • Asus Eee PC 701 4G hangs on boot

    - by Andrew
    I've got an old Eee PC 701 4G with the following specifications: 512 MB RAM 4GB SSD drive SM223AC 8GB SD card extension Screen resolution: 800 x 480 BIOS Revision 1101 (05/16/2008) EC Firmware version: EPC-079 Windows XP SP3 works fine on it, but I decided to switch my OS to Ubuntu. I have downloaded an Ubuntu 10.10 Netbook Remix ISO and wrote it to my FAT32 SD card using Universal-USB-Installer-1.8.3.3, as described on ubuntu.com During standard load from the SD card the boot process hangs up with black screen. If I'll press F6 while preloading Ubuntu, it sucessfully displays the boot menu, selecting language and showing 2 main commands: "Run ubuntu from USB drive" and "Install Ubuntu". Selecting either of these commands leading to the same result - after some background work the main loading indicator is displayed ("Ubuntu" text with dotted progress bar under it), and it's progressing forever without any effect. Is Ubuntu 10.10 compatible with my Eee PC at all? How to boot it correctly?

  • Rebuild package from upstream source?

    - by Andrew
    I'm trying to rebuild a package (specifically grub2) to overcome some bugs that have been fixed upstream but not fixed in Ubuntu, and have the package integrate into Ubuntu properly. The package is hosted in bzr both on Launchpad and GNU Savannah. How can convert a "raw" upstream source package into an "Ubuntu" version and recompile/repackage it? I've worked out that I can get the latest Ubuntu version of the package source with apt-get source, but there are significant differences to the upstream version. What is the best course of action here?

  • Problems after installing Ubuntu 11.10

    - by Andrew Orr
    I'm having trouble with Ubuntu 11.10. It has to do with nomodeset. After I boot into Ubuntu, it goes to a purple screen for about 10 seconds and then goes blank. After that nothing happens. I've read other people's questions about this and I know it has to do with enabling nomodeset. This worked for me when I was using the LiveCD mode, but now Ubuntu is permanently installed as a dual-boot system. Going into recovery mode doesn't work, pressing "e" in the boot loader and writing nomodeset after quiet splash doesn't work either. Holding shift any time it's booting doesn't work. I don't know what to do anymore. I have an HP Pavilion dv6 laptop with an AMD A6-3400M CPU, and my GPU is an AMD Radeon HD 6520G. I've never worked with Linux before so taking me through this step-by-step would be great. Thanks!

  • Design pattern for logging changes in parent/child objects saved to database

    - by andrew
    I’ve got a 2 database tables in parent/child relationship as one-many. I’ve got three classes representing the data in these two tables: Parent Class { Public int ID {get; set;} .. other properties } Child Class { Public int ID {get;set;} Public int ParentID {get; set;} .. other properties } TogetherClass { Public Parent Parent; Public List<Child> ChildList; } Lastly I’ve got a client and server application – I’m in control of both ends so can make changes to both programs as I need to. Client makes a request for ParentID and receives a Together Class for the matching parent, and all of the child records. The client app may make changes to the children – add new children, remove or modify existing ones. Client app then sends the Together Class back to the server app. Server app needs to update the parent and child records in the database. In addition I would like to be able to log the changes – I’m doing this by having 2 separate tables one for Parent, one for child; each containing the same columns as the original plus date time modified, by whom and a list of the changes. I’m unsure as to the best approach to detect the changes in records – new records, records to be deleted, records with no fields changed, records with some fields changed. I figure I need to read the parent & children records and compare those to the ones in the Together Class. Strategy A: If Together class’s child record has an ID of say 0, that indicates a new record; insert. Any deleted child records are no longer in the Together Class; see if any of the comparison child records are not found in the Together class and delete if not found (Compare using ID). Check each child record for changes and if changed log. Strategy B: Make a new Updated TogetherClass UpdatedClass { Public Parent Parent {get; set} Public List<Child> ListNewChild {get;set;} Public List<Child> DeletedChild {get;set;} Public List<Child> ExistingChild {get;set;} // used for no changes and modified rows } And then process as per the list. The reason why I’m asking for ideas is that both of these solutions don’t seem optimal to me and I suspect this problem has been solved already – some kind of design pattern ? I am aware of one potential problem in this general approach – that where Client App A requests a record; App B requests same record; A then saves changes; B then saves changes which may overwrite changes A made. This is a separate locking issue which I’ll raise a separate question for if I’ve got trouble implementing. The actual implementation is c#, SQL Server and WCF between client and server - sharing a library containing the class implementations. Apologies if this is a duplicate post – I tried searching various terms without finding a match though.
