  • Review: Logitech t620 Touch Mouse and Windows 8

    - by Tim Murphy
    It isn’t very often that I worry much about hardware, but since I heard some others talking about “touch” mice for their Windows 8 machines I figured I would try one out and see what the experience was.  The only Windows 8 compatible touch mouse that they had in the store was the Logitech t630 Touch Mouse.  At $69 it isn’t exactly a cheap purchase. So how does it work with Windows 8.  First it works well as a normal mouse with touch scroll capabilities.  Scrolling works both horizontally and vertically.  Then you get into to the Win8 features, all of which are associated with the back 2/3 of the mouse.  If you double-touch-tap (not depressing the internal button) it acts as a Windows home screen button.  The next feature is switching applications.  This is accomplished by dragging a finger from the left edge of the mouse in.  Bringing up the Windows 8 open apps list is the same movement as on the table where you drag in from the left and then move back to the right.  The last gesture available is to bring up the charms.  This is performed by dragging in from the right side of the mouse. There is a certain amount of configurability.  You can switch dominant hand configuration as well as turn on and off gestures as shown in the screenshot below. It is nice that they kept the gestures similar to the table gestures.  Hopefully future updates to the drivers will bring other gestures, but this is definitely a good start.  It would be interesting to also compare this to the Microsoft Touch Mouse and see if there are additional gestures such as app close and for the app bar. del.icio.us Tags: Logitech,Windows 8,Win8,t620,Logitech t620 Touch Mouse,Gesture

  • Nullable types and ?? operator C# [en-US]

    - by ruimachado
    Nullable types vs Non-nullable types   While developing our C# projects its frequent the null comparison operation to avoid null exceptions. This simple operation is mainly coded using the "var x = null" code example inside an if clause. However not all types of variables are nullable, which means that setting a variable to null is not allowed in every cases, it depends on what kind of type are you defining. But what if there was an extension to your non-nullable type that would convert your variable types to nullable? This extension really exists. As I said before in C# you have nullable types which represent all the values of an underlying type, and an additional null value and can be declared easily using "T?", where T is the type of the variable and for example the normal int type cannot be null, so its a non-nullable type, however if you define a "int?" your variable can be null, what you do is convert a non-nullable type to a nullable type. Example: int x=null;     Not allowed     int? x=null;   Allowed     While using nullable types you can check if a variable is null the same way you do it with nullable types:     But what about setting a default value when a certain variable is null?   In this cases the c# .net framework let you set a default value when you try to assign a nullable type to a non-nullable type, using the ?? operator. If you don't use this operator you can still catch the InvalidOperationException which is throw in this cases. For example  without the ?? operator :     Using the ?? operator your code becomes cleaner and more easy to read and you get a bonus, you can set a default value for multiple variables using the ?? in a chain set.     That’s it,   Thanks, Rui Machado rpmachado.wordpress.com

  • Fun programming or something else?

    - by gion_13
    I've recently heard about android's isUserAGoat method and I didn't know what to think. At first I laughed my brains out, than I was embarrassed for my lack of professionalism and tried to look into it and see if it makes any normal sense. As it turns out it is a joke (as stated here) and it appears that other languages/apis have these sort of easter eggs implemented in their core. While I personally like them and feel they can be a fresh breath sometimes, I think that they also can be both frustrating and confusing (and you begin to ask yourself : "can users be goats?" or "I get it! "goat" is slang for.... wait.."). My question is are there any other examples of these kind of programming jokes and what are their intends? Should they be considered harmless or not (how do programmers feel about it) ? Do they reach their goal (if any other than to laugh) ? Where do you draw a line between a good joke and a disaster? (what if the method was called isUserStupid?)

  • So what is Active GridLink for RAC?

    - by Ruma Sanyal
    Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 I had referred to Active GridLink for RAC in my blog yesterday and since then got several questions on this topic. So I decided to re-visit Active GridLink. With the release of version 11g, Oracle WebLogic Server started to provide strong support for the Real Application Clusters (RAC) features in Oracle Database 11g, minimizing database access time while allowing transparent access to rich pooling management functions that maximizes both connection performance and availability. WebLogic is the only application server in the marketplace which has been fully integrated and certified with Oracle Database RAC 11g without losing any rich functionality. Active GridLink provides Fast Connection Failover (FCF), Runtime Connection Load-Balancing (RCLB), and RAC instance graceful shutdown. With the key foundation for providing deeper integration with Oracle RAC, this single data source implementation in Oracle WebLogic Server supports the full and unrestricted use of database services as the connection target for a data source. For more details and to understand how our customer NEC leverages this capability, read the whitepapers on this topic. Get in depth ‘how-to’ details from this youtube video from our resident expert, Frances Zhao.

  • How to manage Agile developers working with traditional (serial) business persons?

    - by Riggy
    Good afternoon, My work environment has some problems. Our IT team is trying to be more agile, but we're not really getting buy-in from the business. They attend our daily stand-ups and sprint reviews, and they help with sprint planning, but then they turn around and do 4 months of requirements gathering for a project before moving forward with a (mostly) serial development style. The sprint goals are things like "get XX% closer to release". For the IT team, they've turned the Sprints into a sort of death march. We end a Sprint one day and start a new Sprint the very next day. There's no reflection or changes done between sprints, only during. Having never done any of the agile methodologies before, I haven't had a very pleasant introduction to them. So my questions are: 1) Should there be some time (perhaps a week or so) between sprints to do the reflection/introspection/changes/etc.? Or are back-to-back-to-back sprints the norm? 2) Is there any chance for survival for an agile team with no agile business counter-parts? If not, are there some transitional methodologies or even tips for moving the business towards an iterative if not necessarily agile mindset? 3) Should your entire team be on every sprint? We have almost 20 programmers on a single sprint but working on completely different projects (typically teams of 3-5, sometimes larger). Is it normal to have a single sprint or should we be trying to manage multiple independent sprints? Should we be trying to keep the multiple sprints in concurrent lockstep or should their timetables be allowed to overlap and be flexible? Any thoughts or advice is appreciated. This is my first time coming over from SO for a question, so please let me know if there are better ways to phrase these kinds of questions (faq was rather helpful, but still not sure I'm following it perfectly). Thanks!

  • How to automatically mount a folder and change ownership from root in virtualbox

    - by Fiztban
    It is my first time using virtualbox and ubuntu (14.04), I am on a host Windows 7 OS. I am trying to mount a shared folder that has files I need to access both in the virtualbox and on the windows OS. I have successfully mounted them using the vboxsf from the Guest Additions installed. To mount I used the command sudo mount -t vboxsf <dir name in vbox> <directory in linux for example I used sudo mount -t vboxsf Test /home/user/Test I found several ways of mounting the directories automatically upon startup using for example the /etc/rc.local method (here) where you modify said file appending the command to it (without sudo). Or by using the fstab method (here). I prefer the rc.local method personally. Once mounted it has permissions dr-xr-xr-x however once mounted the directory is of root ownership and chown user /home/user/Test has no effect. This means I cannot make or change files in it as a normal user. In the VirtualBox the directory to be shared is not set as read-only. Is there a way to automatically mount the shared folder and assign ownership to my non root user?

  • Cannot boot: FGLRX 8.780 + Kernel 2.6.35-25

    - by pluc
    The situation before this all happened is pretty standard. I have a HP Pavillion dv5 laptop with an ATI Mobility Radeon 4200 series. It always worked fine with Ubuntu for as long as I can remember. However, at one point, something happened and truly made a majestic mess of things. It might've been extra repos I enabled with Ubuntu Tweak - I do not know. But something made it so that my system would not boot any longer. And when I say "won't boot", this is what I mean: - Durning a normal bootup, any entries (except Windows) selected with GRUB (or BURG, not even sure which one I'm using anymore) will spawn the Ubuntu loading screen - then try to start X (or GDM) 5 times. The screen goes to dark, black and back to the Ubuntu loading screen. Then it just stays there until I spawn another TTY. I have no idea what is happening or why. There are no errors in my logs, and I'm truly at a loss here. I've linked three files: Xorg.0.log, the output of dmesg and the GDM log: Xorg.0.log: http://ubuntu.pastebin.com/tpVKc2tc dmesg: ubuntu.pastebin.com/Nd5aYj45 gdm's :0.log: couldn't post due to lack of points :( Let me know if any of you more knowledgeable folks can restore some sanity in my life. Any help is greatly apreciated.

  • JQueryMobile - Problems with dialog boxes [closed]

    - by Richard van Hees
    I'm programming in JQueryMobile, but I can't seem to get some things as I want. First it's good to tell I am mostly programming in a multi-page template. I have a login function in the web based app. The idea is that the user sees he's not logged in and the user can click on the button to log in. A dialog box pops up, in which the user can enter his credentials. This dialog box is in front of the previous page, in my case just index.php. The page for profile is at profile.php#profile. In this case the url for the dialog box is index.php#profile&ui-state=dialog. Don't ask me why, that's how JQueryMobile works, I guess. Anyway, after the user clicks on 'Login' in the pop-up, I want a new dialog to pop-up in which it says you are logged in and I want the content of the page behind it (index.php#profile) to refresh. Of course I want this all to move very smooth and no refreshing of the whole page, to prevent loading time and thus a blank screen for a second. In short: User not logged in Clicks on login Dialog pops up with form Clicks login New dialog pops up with 'success' (or whatever) in the same style as the previous dialog Clicks ok Page behind the dialogues has been refreshed without user noticing Also another thing that doesn't really work out for me: I can't seem to get a dialog to pop up, triggered by an action in another dialog. It just appears as a normal page.

  • Can't install Ubuntu 12.04 64-bit on a dual-drive MacBook Pro 8,2

    - by kizdp
    Good afternoon, this is the first time I participate here as I'm new to Linux. I've been trying to solve the following problem for over a week without any sign of success so I hope there's a much more knowledgeable person here that can give me a solution. I have an early 2011 MacBook Pro (8,2) with Mac OS X running in a SSD. Then, instead of the Optical bay, I have a HDD in where I would like to install Ubuntu to run it natively. I've tried to do the normal installation process, with or without rEFIt, but it seems the problem resides on the communication between the device containing the Ubuntu .iso file and the laptop. It doesn't allow communication with the boot CD or USB drive. It usually says: “Loading bootlogo...” after I click on the “boot from CD, Linux Icon”. After trying several things, I would like to know if I could install Ubuntu on the HDD as an external HDD (using a friend's Window's system) and then simply put it back into my laptop so as to become an Internal HDD again. I guess, I would have to reinstall many drivers and so on, but would this approach work? Thanks in advance and sorry for this huge block of text

  • Can't install Ubuntu in Windows 8

    - by user171635
    I’ve been trying to install Ubuntu 13.04 64-bit edition on an ASUS (K53Z) laptop. I have Windows 8 64-bit installed in a non UEFI mode (I think since it starts-up with the Windows logo and I don’t have the UEFI settings). This laptop had installed Windows 7 and when I upgraded it I didn’t knew about the UEFI advantages. I tried several times to install Ubuntu from a USB device and it loads the logo and then I can’t go further in the installation. I thought it was the version of Ubuntu and tried to install Fedora (even if I personally prefer Ubuntu). I had the same problem: Fedora’s logo appears and it gets stuck. I tried also to boot from different USB devices and didn’t work either. My Bios has EFI options to boot but they were not enabled. So I tried to enable them to boot the USB in UEFI mode. A menu shows up with the options of install Ubuntu and try Ubuntu. If I click the Install or try option, I get a black screen and I can’t go further with the install (which I think is normal since I don’t have Windows 8 in EFI mode). My hypothesis is that the Bios isn’t letting Ubuntu write or read from my SSD, because the activity LED in the USB memory is on when it’s loading the installation files. Once the files are ready and the Ubuntu logo is loaded I don’t see a LED activity on neither the SSD or the USB. Thanks If I missed data you can ask me.

  • Using Bulk Operations with Coherence Off-Heap Storage

    - by jpurdy
    Some NamedCache methods (including clear(), entrySet(Filter), aggregate(Filter, …), invoke(Filter, …)) may generate large intermediate results. The size of these intermediate results may result in out-of-memory exceptions on cache servers, and in some cases on cache clients. This may be particularly problematic if out-of-memory exceptions occur on more than one server (since these operations may be cluster-wide) or if these exceptions cause additional memory use on the surviving servers as they take over partitions from the failed servers. This may be particularly problematic with clusters that use off-heap storage (such as NIO or Elastic Data storage options), since these storage options allow greater than normal cache sizes but do nothing to address the size of intermediate results or final result sets. One workaround is to use a PartitionedFilter, which allows the application to break up a larger operation into a number of smaller operations, each targeting either a set of partitions (useful for reducing the load on each cache server) or a set of members (useful for managing client result set sizes). It is also possible to return a key set, and then pull in the full entries using that key set. This also allows the application to take advantage of near caching, though this may be of limited value if the result is large enough to result in near cache thrashing.

  • Programming During a Crisis

    - by Duracell
    Hello, I'm having difficulty turning this into a proper question, but here goes... Some of you may have heard about the flooding happening in Queensland, Australia. Well, I'm in the inner suburbs of Brisbane right now; the river has been slowly creeping toward my house since Tuesday. When I left for work this morning it was twenty meters down the road when it is normally kilometers away. Within hours of the distater striking, the government already had some pretty good web applications available for people to get information about what was happening and where the flood was predicted to rise. They also set up a database for people to search for the whereabouts of relatives or could register their location for others to see. Has anyone been involved in the development of these kinds of projects before? It's interesting that they could churn out this software in what appeared to be less than a day when the average development house could take weeks at best. In what ways did it differ from a 'normal' project? Any other thoughts?

  • Default mount options on auto-mounted NTFS partitions (how to add `noexec` and `fmask=0111`?)

    - by jetxee
    I use auto-mounting of external USB devices, and it works as expected, except that NTFS partitions are mounted with executability flag on. For example: /dev/sdb1 on /media/Elements type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096,default_permissions) All normal files are -rwxrwxrwx on this partition. I am not happy with the xs. I know I can have it mounted the way I want if I pass the fmask=0111 option. Now I use Lucid, and suppose it uses some new auto-mounting mechanism (gvfs-mount?), but I don't really know how the default mounting options can be changed now. Gconf settings in /system/storage/default_options/ntfs/mount_options have no effect. So, how do I make fmask=0111 the default automounting option for all NTFS partitions? (I'd be grateful also if someone explains how the current automounting mechanism works, how to configure it, and if the default mounting options are hard-coded, what I have to recompile to change them). I know that I can put a line in the /etc/fstab and/or mount manually, but this is not the solution I want, because 1) I don't want to edit /etc/fstab for each and every external drive I use, 2) fstab records appear in the Places pane of Nautilus, even if the drives are not present. The questions is how to change the defaults.

  • How to make other semantics behave like SV_Position?

    - by object
    I'm having a lot of trouble with shadow mapping, and I believe I've found the problem. When passing vectors from the vertex shader to the pixel shader, does the hardware automatically change any of the values based on the semantic? I've compiled a barebones pair of shaders which should illustrate the problem. Vertex shader : struct Vertex { float3 position : POSITION; }; struct Pixel { float4 position : SV_Position; float4 light_position : POSITION; }; cbuffer Matrices { matrix projection; }; Pixel RenderVertexShader(Vertex input) { Pixel output; output.position = mul(float4(input.position, 1.0f), projection); output.light_position = output.position; // We simply pass the same vector in screenspace through different semantics. return output; } And a simple pixel shader to go along with it: struct Pixel { float4 position : SV_Position; float4 light_position : POSITION; }; float4 RenderPixelShader(Pixel input) : SV_Target { // At this point, (input.position.z / input.position.w) is a normal depth value. // However, (input.light_position.z / input.light_position.w) is 0.999f or similar. // If the primitive is touching the near plane, it very quickly goes to 0. return (0.0f).rrrr; } How is it possible to make the hardware treat light_position in the same way which position is being treated between the vertex and pixel shaders? EDIT: Aha! (input.position.z) without dividing by W is the same as (input.light_position.z / input.light_position.w). Not sure why this is.

  • Agressive Auto-Updating?

    - by MattiasK
    What do you guys think is best practice regarding auto-updating? Google Chrome for instance seems to auto-update itself as soon as it get's a chance without asking and I'm fine with it. I think most "normal" users benefits from updates being a transparent process. Then again, some more technical users might be miffed if you update their app without permission, as I see it there's 3 options: 1) Have a checkbox when installing that says "allow automatic updates" 2) Just have a preference somewhere that allows you to "disable automatic updates" so that you have to "check for updates manually" I'm leaning towards 2) because 1) feels like it might alienate non-technical users and I'd rather avoid installation queries if possible. Also I'm thinking about making it easy to downgrade if an upgrade (heaven forbid) causes trouble, what are your thoughts? Another question, even if auto-updates are automatically, perhaps they should be announced. If there's new features for example otherwise you might not realize and use them One thing that kinda scares me though is the security implications, someone could theorically hack my server and push out spyware/zombieware to all my customers. It seems that using digital signatures to prevent man-in-the-middle attacks is the least you could do otherwise you might be hooked up to a network that spoofs the address of of update server.

  • Independent HTML5 Physics Game: Any Feedback? [closed]

    - by mndoftea
    I've been independently developing a physics-based HTML5 game. I haven't used any libraries or engines; all the code, including the physics, is my own. It is free for a while on the Chrome Web Store and I was hoping that I could get some feedback on it. You can get it for Chrome here: https://chrome.google.com/webstore/detail/dbnmkpcomailjochphnmfklofkmgenci. I know this is not a normal question, but I'm happy for answers to be abstracted/generalized for broader use. Im asking here because I don't know anyone else personally who does this stuff. Any thoughts, comments or ideas you might have would be greatly appreciated! The physics system is written in JavaScript and works by setting up the differential equations of motion (plus a few conditions) and evaluating them numerically using the Euler method. The graphics are done through the HTML5 canvas and the music is done through the audio element. (Said music is in the public domain by the way). You can see the code by going to VIewView Source in Chrome.

  • Lubuntu 12.10: Icon Display Problems

    - by SlcBullseye
    First off, I would like to let you know that I am new to Linux. I finally decided to give it a try and my first project was installing Lubuntu on an old PC and using it for a media server for my PS3. So, one thing that I noticed right away is that my icons for applications, files, folders, etc...are not visible. If I move my mouse over the name of the application or file (It only works if I move the mouse up from the bottom of the name) then the icon will appear, but if I move my mouse back over any other place on the file the icon will disappear again. Also, if I open a folder sometimes an icon or two will be displayed but the rest won't, and like I said before if I move my mouse over the top of the application or file the icon will disappear. Is there any way to fix this? Is this normal? Or could it be a problem with my hardware? I never had this issue when I was running the last OS (Windows XP). Any help would be greatly appreciated. Remember, I am new to Linux so a thorough explanation would be helpful. Also, if there are any tips, tricks, references, or recommendations any of you have to help me jump in and become more familiar with using Linux that would be great! I'm very interested in taking advantage of the power Linux has. Currently I am studying computer programming so maybe one day I will be able to develop my own Linux distribution.

  • Should I indicate that the user exists or was deleted on the error page?

    - by animuson
    On an ordinary public website, the user's profile is always publicly visible to all visitors (such as Stack Overflow), where they can limit certain pieces of information via privacy settings or just removing the information. Now the user has decided to delete their account (in my case deactivate) so that their account doesn't technically "exist" anymore. The way my system is set up, when their account is deactivated, their username for any content connected to them just becomes "Anonymous User" as if it were a guest that posted. I feel like this could cause some confusion for other users. I'm also concerned about what kind of error to display when someone attempts to view their profile page. My gut tells me to just display a standard 404 page to hide the fact that they ever existed, but then you also have to consider that, since usernames must be unique, anyone can go to the register page and type in the username to see if it really exists or not. I have a similar problem with another website, which gives users the ability to hide their profiles from the public and only allow registered users to view it. Again it's with the dilemma of what kind of error message to display when an unregistered users attempts to view their profile with invalid permissions. So, would it be acceptable to display basic errors such as "user has been deactivated" or "you must be logged in to view this profile" in order to give other visitors some idea of why the page can't be displayed, or should I attempt to cover the user's privacy a little and just display a standard 404 without indicating in any way that the user might exist? Are there any other issues that I'm not realizing about either route? To go back to the beginning, should I even bother changing the user's name to "Anonymous User" when their account is deactivated? Would it be acceptable to just display a non-linked version of their username in place of the normal linked display name?

  • Android: Not able to experiment on own?

    - by user221287
    I have just started learning Android App Development a few days ago, with prior knowledge of C/C++, HTML and CSS. This is the situation I am facing Repeatedly: I am learning from a Video Tutorial Series, after each video, or each few videos, I say myself: Let's use what I have just learnt in the simple (and also "meaningless") app that I have made so far by watching the tutorials. I start implementing it, but then after a few minutes, I realize that I cannot do it because I do not know a few other syntax related to the particular thing, (or) I do not know whether these things can be combined with these other things by the use of . (dot). Whatever I try, I get either an error in eclipse or "Sorry...the app com.example.simple has stopped unexpectedly...." when the app runs. Then I search StackOverflow, Google and learn that what I want to implement requires learning about a few more classes, syntax and creating a few more java classes. I am not able to experiment on my own. Is it normal? Is it the HARD-WAY in which one is supposed to learn? Should I first learn Java and then come back to Android - would that be helpful?

  • Ubuntu automatic logout whenever I execute exe files

    - by KeepTrying
    I have a problem. Here's the thing. There were 4 partitions in my hard drive: One for ubuntu root folder One for ubuntu home folder One for general stuffs like music, movies... And the last one for SWAP To install Windows 7, I resized partitions and moving the order of partitions by using GParted. I moved all of the ext formatted partitions to the left, so that means the spare space would be at the right. And I formatted that spare space in NTFS and install windows 7. After successfully installing windows 7, I used LiveUSB to fix grub. I installed Boot Repair and, with just one click, now I can dual boot ubuntu and windows 7. But, the point, because of changing the order of partitions, especially the partition consisting of home folder, I couldn't log in the ubuntu. I used recovery mode and changed file /etc/passwd. Everything almost got back to normal except one thing. The windows apps that I installed via wine don't work anymore. I run them via accessing menu Applications/Wine/Programs but nothing loads. One more thing, when I double click on exe files to run them, ubuntu suddenly log outs. Thank you for reading my post, it's quite long and my English is fairly poor. I'd appreciate for anyone who reads it.
