  • Barnes & Noble Slashes Lighted Nook Price to a Kindle-Competitive $119

    - by Jason Fitzpatrick
    In a bit of market battling that benefits everyone, Barnes & Noble has slashed the price of the Nook Simple Touch with Glowlight–their closest match to the Kindle Paperwhite–to $119. The new listing, in addition to showing off the lowered price, includes a not-so-subtle jab against the Kindle: “No Ads. Power adapter included.” While the Glowlight is a great little ebook reader, Barnes & Noble is on the defensive after a week of hands-on-hardware reviews of the Kindle Paperwhite left many reviewers proclaiming it king of the e-readers and heaping on mountains of praise.

  • Overriding equals, hashCode and toString in a Clojure deftype

    - by mikera
    I'm trying to create a new type in Clojure using deftype to implement a two dimensional (x,y) coordinate, which implements a "Location" protocol. I'd also like to have this implement the standard Java equals, hashCode and toString methods. My initial attempt is: (defprotocol Location (get-x [p]) (get-y [p]) (add [p q])) (deftype Point [#^Integer x #^Integer y] Location (get-x [p] x) (get-y [p] y) (add [p q] (let [x2 (get-x q) y2 (get-y q)] (Point. (+ x x2) (+ y y2)))) Object (toString [self] (str "(" x "," y ")")) (hashCode [self] (unchecked-add x (Integer/rotateRight y 16))) (equals [self b] (and (XXXinstanceofXXX Location b) (= x (get-x b)) (= y (get-y b))))) However the equals method still needs some way of working out if the b parameter implements the Location protocol. What is the right approach? Am I on the right track?

  • UIAlertView crashing on undocumented method

    - by morticae
    Our app has been crashing with a frequency of roughly 1 in 1,500 launches due to a bug that is proving elusive. The relevant portion of the stack trace is included. It's being fired as a callback so I have no reference for where it's occurring in my own code. It looks like what's going on is there is a UIViewAnimationState object that is calling UIAlertView's private method (_popoutAnimationDidStop:finished:). Only problem is, it appears the UIAlertView has been dealloced by this point. I don't do anything weird with alert views. I throw them up, and I wait for user input. They are all shown before being released. Anyone encountered this? At this point, I'm leaning toward it being an Apple bug. Thread 0 Crashed: 0 libobjc.A.dylib 0x3138cec0 objc_msgSend + 24 1 UIKit 0x326258c4 -[UIAlertView(Private) _popoutAnimationDidStop:finished:] 2 UIKit 0x324fad70 -[UIViewAnimationState sendDelegateAnimationDidStop:finished:] 3 UIKit 0x324fac08 -[UIViewAnimationState animationDidStop:finished:] 4 QuartzCore 0x311db05c run_animation_cal lbacks

  • C# Training Quizzes

    - by John Sheppard
    Hello there, I have been programming 10 years, mostly in vba and vb.net but I know c# well enough to program what I normally do. I yesterday was applying for a Senior c# position and I did so poorly on the induction test its not funny :) I have always found that for me the best way to learn and recall is via question's and answers (multichoice and short answer). That is, a question is posed and after I answer instant feedback is given as to whether I choose right or wrong and the reasons why. As such I was wondering if anyone knew of or could recommend a C# quiz website. Something like a daily c# quiz to keep my brain up to date and fresh if I'm not always programming in it. Not something wimpy either. Something that does everything. Paying is not an obstacle, id prefer to pay for a good resource than muck around. Thank you

  • BDE, Delphi, ODBC, SQL Native Client & Dead lock

    - by EspenS
    Hi. We have some Delphi code that uses the BDE to Access SQL Server 2008 through the SQL Server Native Client ODBC driver (2005 version). Our issue is that we're experiencing some deadlock issues in a loop doing inserts to multiple tables. The whole loop is done within a [TDatabase].StartTransaction. Looking at the SQL Server Profiler we clearly see that at one point during the loop the SPID (Session ID?) change, and then we naturally end up with a deadlock. (Both SPID doing inserts to the same table) It seems like the BDE at some point does a second connection to the DB... (Although I would love to skip the BDE, it's currently not possible. ) Anyone with experiences to share?

  • .NET WinForms INotifyPropertyChanged updates all bindings when one is changed. Better way?

    - by Dave Welling
    In a windows forms application, a property change that triggers INotifyPropertyChanged, will result in the form reading EVERY property from my bound object, not just the property changed. (See example code below) This seems absurdly wasteful since the interface requires the name of the changing property. It is causing a lot of clocking in my app because some of the property getters require calculations to be performed. I'll likely need to implement some sort of logic in my getters to discard the unnecessary reads if there is no better way to do this. Am I missing something? Is there a better way? Don't say to use a different presentation technology please -- I am doing this on Windows Mobile (although the behavior happens on the full framework as well). Here's some toy code to demonstrate the problem. Clicking the button will result in BOTH textboxes being populated even though one property has changed. using System; using System.ComponentModel; using System.Drawing; using System.Windows.Forms; namespace Example { public class ExView : Form { private Presenter _presenter = new Presenter(); public ExView() { this.MinimizeBox = false; TextBox txt1 = new TextBox(); txt1.Parent = this; txt1.Location = new Point(1, 1); txt1.Width = this.ClientSize.Width - 10; txt1.DataBindings.Add("Text", _presenter, "SomeText1"); TextBox txt2 = new TextBox(); txt2.Parent = this; txt2.Location = new Point(1, 40); txt2.Width = this.ClientSize.Width - 10; txt2.DataBindings.Add("Text", _presenter, "SomeText2"); Button but = new Button(); but.Parent = this; but.Location = new Point(1, 80); but.Click +=new EventHandler(but_Click); } void but_Click(object sender, EventArgs e) { _presenter.SomeText1 = "some text 1"; } } public class Presenter : INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; private string _SomeText1 = string.Empty; public string SomeText1 { get { return _SomeText1; } set { _SomeText1 = value; _SomeText2 = value; // <-- To demonstrate that both properties are read OnPropertyChanged("SomeText1"); } } private string _SomeText2 = string.Empty; public string SomeText2 { get { return _SomeText2; } set { _SomeText2 = value; OnPropertyChanged("SomeText2"); } } private void OnPropertyChanged(string PropertyName) { PropertyChangedEventHandler temp = PropertyChanged; if (temp != null) { temp(this, new PropertyChangedEventArgs(PropertyName)); } } } }

  • C++ stack memory still valid?

    - by jbu
    Hi all, If I create an object on the stack and push it into a list, then the object loses scope (outside of the for loop in the example below) will the object still exist in the list? If the list still holds the object, is that data now invalid/possibly corrupt? Please let me know, and please explain the reasoning.. Thanks, jbu class SomeObject{ public: AnotherObject x; } //And then... void someMethod() { std::list<SomeObject> my_list; for(int i = 0; i < SOME_NUMBER; i++) { SomeObject tmp; my_list.push_back(tmp); //after the for loop iteration, tmp loses scope } my_list.front(); //at this point will my_list be full of valid SomeObjects or will the SomeObjects no longer be valid, even if they still point to dirty data }

  • Walmart and Fusion Apps

    - by ultan o'broin
    Photograph: Misha Vaughan I attended Fusion Apps (yes, I know I am supposed to say "Oracle Fusion Applications", but stuffy old style guides are a turn-off in interwebs conversations) User Experience Advocate (FXA) training in Long Beach, California last week; a suitable location as ODTUG KSCOPE 11 was kicking off and key players were in the area. As a member of Oracle's Apps-UX team I know the Fusion Apps messaging, natch, and done some other Fusion Apps go-to-market content work too. For the messaging details themselves, see Lonneke Dikmans (@lonnekedikmans) great blog, by the way. However, I wanted some 'formal' training combined with the opportunity to meet and learn from people already out there delivering those messages. The idea in me reaching out to Misha Vaughan, Apps-UX FXA maven, to get me onto this training was that in addition to my UX knowledge, I could leverage my location in EMEA and hit up customer events more quickly and easily. Those local user groups do like to hear the voice of locals too you know (so I need to work on that mid-Atlantic accent). I'm looking forward to such opportunities. The training was all smashing stuff, just the right level of detail, delivered professionally and with great style and humor. I was especially honored to be paired off for my er, coaching with Debra Lilley (@debralilley), who shared with everyone all kinds of tips and insights from her experiences of delivering the message and demo. For me, that was the real power of the FXA event--the communal, conversational aspect--the meeting up with people who had done all this for real, the sharing in their experiences, while learning along with other newbies. Sorry, but that all-important social aspect doesn't work so well with remote meetings. Katie Candland (Apps-UX) gave us a great tour of the Fusion Apps demo and included some useful presentational tips too (any excuse to buy that iPad). It's clear to me that the Fusion Apps messaging and demos really come alive with real-world examples that local application users will recognize, and I picked up some "yes, that's my job made easier" scene-stealers from Debra and Karen Brownfield too, to add to the great ones already provided. This power of examples shouldn't surprise anyone, they've long been a mainstay of applications user assistance, popular with users. We'll offer customers different types of example topics in the Fusion Apps online help too (stay tuned), and we know from research how important those 3S's (stories, scenarios, and simulations) are to users when they consume and apply information. Well, we've got the simulation, now it's time for more stories and scenarios. If you get a chance to participate in an FXA event (whether you are an Oracle employee or otherwise), I'd encourage it. It's committing your time and energy for sure, but I got real bang for the buck from it for my everyday job too. Listening to the room's feedback on the application demo really brought our internal design work to life, and I picked up on some things that I need to follow up on (like how you alphabetically sort stuff in other languages). User experience is after all, about users. What will I be doing next, and what would I like to see happen? Obviously, I need to develop my story-telling links with the people I met in Long Beach and do some practicing with the materials, and then get out there and deliver them at a suitable location. The demo is what it is right now, and that's a super-rich demo that I know everyone will want to see and ask questions about. Then, as mentioned by attendees at the FXA event, follow up on those translated and localized messages for EMEA (and APAC), that deal with different statutory or reporting requirements of the target markets. Given my background I would say that, wouldn't I? However, language is part of the UX, and international revenue is greater than US-only revenue for Oracle, so yes dear, we all need to get over the fact that enterprise apps users don't all speak, or want to speak, American-English. Most importantly perhaps, the continued development of a strong messaging community between Oracle and partners and customers where we can swap and share those FXA messaging stories and scenarios about Fusion Apps in a conversational way. The more the better, a combination of online and face-to-face meetings. I must also mention the great dinner after the event at Parker's Lighthouse, and the fun myself and Andrew Gilmour (Apps-UX) had at our end of the table talking about just about everything except Fusion Apps with Ronald Van Luttikhuizen and Ben Prusinski (who now understands the difference between Cork and Dublin people. I hope). Thanks to all the Apps-UXers who helped bring the FXA training to town, and to Debra and all the others that I am too jetlagged to mention right who were instrumental in making it happen for me. Here's to the next one. And the Walmart angle? That was me doing my Robert Scoble (ScO'bilizer?)-style guerilla smart phone research in Walmart in Long Beach, before the FXA event. It's all about stories for me. You can read more about it on the appslab blog (see the comments).

  • Using TortoiseHg to push to an authenticated git repository

    - by Nathan Palmer
    I'm trying to push a changeset from a local Mercurial repository created with TortoiseHg to a remote Git repository. I have hg-git installed and configured and it will pull just fine. But when I run the push it gives me this Command hg push git+ssh://git@dummyrepo:username/repo.git Result pushing to git+ssh://git@dummyrepo:username/repo.git importing Hg objects into Git creating and sending data abort: the remote end hung up unexpectedly There are several things I've done to get to this point. But I'm hoping to resolve this last thing because I find TortoiseHg to be much easier to work with than any of the Git tools out there (for windows.) Installed TortoiseHg Pulled down the hg-git from http://bitbucket.org/durin42/hg-git/ Configured mercurial.ini to point to the hg-git library Pulled down dulwich source from git://git.samba.org/jelmer/dulwich.git Compiled dulwich and put it into library.zip for TortoiseHg Configured TortoiseHg to use TortoisePlink.exe for ssh Added my private key to Pageant Any ideas what I could be missing?

  • Storing website hierarchy in Sql Server 2008

    - by Mika Kolari
    I want to store website page hierarchy in a table. What I would like to achieve is efficiently 1) resolve (last valid) item by path (e.g. "/blogs/programming/tags/asp.net,sql-server", "/blogs/programming/hello-world" ) 2) get ancestor items for breadcrump 3) edit an item without updating the whole tree of children, grand children etc. Because of the 3rd point I thought the table could be like ITEM id type slug title parentId 1 area blogs Blogs 2 blog programming Programming blog 1 3 tagsearch tags 2 4 post hello-world Hello World! 2 Could I use Sql Server's hierarchyid type somehow (especially point 1, "/blogs/programming/tags" is the last valid item)? Tree depth would usually be around 3-4. What would be the best way to achieve all this?

  • Fails to boot after upgrade, stuck on winbind package

    - by Praetorian
    I started the upgrade from 11.04 to 11.10 last night. Once it got the installing packages part I left the computer unattended the rest of the night. When I checked it this morning the screen was blank and I couldn't get it to turn on. So I cycled power, and now I get the "Ubuntu 11.10" screen with the dots underneath, but then it gets to a blank screen and nothing more. I can get to the command line in recovery mode; here's a list of the things I've tried so far sudo apt-get update - the very first repository it checked sat at 0% for a long time (network cable is plugged in), so I cancelled with Ctrl+C Thought it might be a problem with display drivers, so I tried sudo apt-get install nvidia-glx - this gave me an error saying dpkg has been interrupted, manually run sudo dpkg --configure -a sudo dpkg --configure -a this installed / updated a bunch of stuff but got stuck at Starting Winbind daemon winbind Restarted and tried sudo dpkg --configure -a again but it gets stuck at same Windbind step What else can I do to fix this problem?

  • How to Install Nvidia Drivers

    - by Richard Rodriguez
    I just ordered the Nvidia GTX 560 card, which should arrive tomorrow. I have a dilemma, though. Should I keep using the driver which is available in "additional drivers" in Ubuntu (10.10), or should I install the driver from the nvidia site? NOTE - The methods to install explained here apply to all Nvidia, Ati & Intel video cards The latest driver available at the nvidia site: LINUX X64 (AMD64/EM64T) DISPLAY DRIVER Version: 280.13 Certified Release Date: 2011.08.01 Operating System: Linux 64-bit Language: English (U.S.) File Size: 52.4 MB I should point out that I don't need the card to unleash its full potential in Ubuntu (I have Windows for gaming, other HDD), I just need it to work properly, that meaning the power saving should work (I don't want the card to overheat for no reason), also I would like the fans to work at proper speeds, etc. So which driver is the best for me?

  • Once mounted using TrueCrypt, cannot unmount

    - by zeiger
    I have an external HDD and use TrueCrypt for keeping encrypted file containers. After mounting, whenever I try to dismount a file container (using TrueCrypt 7.0a on Ubuntu 11.04), it just does not happen and I get the following message: device-mapper: remove ioctl failed: Device or resource busy Command failed Further, if I close TrueCrypt and then try to start it again, it says that TrueCrypt is already running, but I cannot access it from the Unity sidebar (because it is not there). Also, if I power down my external HDD, the TrueCrypt volume still shows as one of the mounted volumes, but I cannot do anything with it. Any possible work around? I remember this NOT happening in earlier versions of Ubuntu so I am guessing there is something to do with 11.04. Thanks

  • How to enable true remote login

    - by Scán
    I don't quite know how these things are called, so a search did not product any help. I've got two computers, a desktop and a netbook. The netbook is really weak, and there's hardly any fun doing work with it, especially after ubuntu software swallows so much cpu power for nothing. But my desktop is good, but uncomfortably positioned. So I know you can use any linux system as a server to give logins. I want to be able to login and work on my desktop, from my netbook. No VNC, no SSH, full X-server, I want to be able to choose "Login on Desktop" in my login menu on the netbook and have everything as if I was there. I hope I could make my point. Is it possible in a local network? And if so, how can I easily set it up?

  • Game Clock Precision

    - by Philip
    I'm reading a fantastic article about game timer precision and here is a quote about 2/3 of the way into the article: If you start your game clock at about 4 billion (more precisely 2^32, or any large power of two) then your exponent, and hence your precision, will remain constant for the next ~4 billion seconds, or ~136 years. He doesn't give a concrete example of this though. Does this mean I would want to add 2^32 to the game clock value that I store at the beginning of each frame? Or is there a way to actually set the clock in Windows so that the numbers start at 2^32?

  • Static libraries, dynamic libraries, DLLs, entry points, headers ... how to get out of this alive?

    Hello, I recently had to program C++ under Windows for an University project, and I'm pretty confused about static and dynamic libraries system, what the compiler needs, what the linker needs, how to build a library ... is there any good document about this out there? I'm pretty confused about the *nix library system as well (so, dylibs, the ar tool, how to compile them ...), can you point a review document about the current library techniques on the various architectures? Note: due to my poor knowledge this message could contain wrong concepts, feel free to edit it. Thank you Feel free to add more reference, I will add them to the summary. References Since most of you posted *nix or Windows specific references I will summarize here the best ones, I will mark as accepted answer the Wikipedia one, because is a good start point (and has references inside too) to get introduced to this stuff.

  • Creating an installer with WPF forms, packaged files and custom setup actions in C#

    - by RodH257
    I'm trying to create a way of deploying a set of tools (which are add-ins to 3rd party software) to my users. I would like to do the following: User Enters Serial Dlls in their directory structure is extracted to program files a file is copied to a location in ProgramData (this registers my add-ins to the 3rd party application) Online activation for software is performed Can anyone point me into the right direction for this? I had a look at deployment projects in Visual Studio but I'm not sure if they are what I'm after. Main problem is they are ugly, I would like to have a nice WPF installer, and have a more custom experience. But I guess that can be traded off if its going to make things easier. I was thinking, I could just make my own C# project that extracts the files, but I have no idea how to package them up and extract them all as part of one download (like the MSI files that the deployment projects create). Can anyone point me in the right direction?
