  • 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

  • 5 year old ubuntu system, always dist-upgraded => ok. however some tasks remain

    - by knb
    I have a PC with a current ubuntu distribution installed. I've upgraded many times since 5.10. It always went well, however some tools or features were kindof left behind in a unsatisfactory state: grub to grub2 - is it an really necessary to switch the boot loader some time to grub2. Upgrading this scares me abit. I still have ext3 devices - is it worth upgrading to ext4? should I wait for btrfs? hibernation and suspend- it only worked in 5.10, since 6.04 it was messed up. Should I really care? Any chance to repair this myself? Simply by cleanup or hacking config files. It is a desktop PC after all. So energy saving functionality is not really needed. I am using vmware workstation 6.5 and the latest kernel that supports it is 2.6.32. This is my default kernel now, ignoring 2.6.35. Am I missing anything important in the new kernel now?

  • What is the correct way to install Gnome Shell 3.6 on Ubuntu 12.10?

    - by user74660
    I don't want to use Ubuntu Gnome Remix because I think it is kind of "incomplete". I prefer to install Gnome Shell on Ubuntu 12.10. I've searched the net for instructions on how to do it and found two different ways: Simply search for Gnome Shell on Ubuntu Software Center and install it. Follow the instructions from this WebUpd8's post. Now, my doubt is: what is the differecen between the two methods? Which is the correct way to do it? Does the first one lack features? If so, which ones? Is the second one better? Why? Is there a third and better method I haven't found? By the way, I have already tried (for testing purposes) the second method (WebUpd8's) and noticed that it installed some apps I really don't want to have, such as AbiWord and Gnumeric, because they are Gnome's default applications. So, "if" the second method is the way to go, I can certainly remove those apps manually, after installation, with no worries, right? Thank you very much for your attention.

  • 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?

  • Who extends interfaces? And why?

    - by Gangnus
    AFAIK, my class extends parent classes and implements interfaces. But I run across a situation, where I can't use implements SomeInterface. It is the declaration of a generic types. For example: public interface CallsForGrow {...} public class GrowingArrayList <T implements CallsForGrow> // BAD, won't work! extends ArrayList<T> Here using implements is syntactically forbidden. I thought first, that using interface inside < is forbidden at all, but no. It is possible, I only have to use extends instead of implements. As a result, I am "extending" an interface. This another example works: public interface CallsForGrow {...} public class GrowingArrayList <T extends CallsForGrow> // this works! extends ArrayList<T> To me it seems as a syntactical inconsistancy. But maybe I don't understand some finesses of Java 6? Are there other places where I should extend interfaces? Should the interface, that I mean to extend, have some special features?

  • How to mount a network drive?

    - by Relik
    Ok so I'm trying to set-up a home file server. I'm thinking about just setting it up as an FTP server, no particular reason other than I'm familiar with FTP and samba tends to be very frustrating. Basically the set-up I'm going for, is to be-able to create multiple user accounts for the server and restrict or allow access to specific folders on each user. FTP is the only way (that I know of) to accomplish a set-up like that. My question is how can I mount an FTP server as a drive in Ubuntu so that all my applications can access it just like any other driver or folder. An example would be downloading 12.10 via torrent when it comes out, I would like to be able to tell transmission to just download the file straight to my ftp server. I know how to do this in Windows, its actually very easy. But I cant figure it out in Ubuntu. I have tried using the "connect to server" option in nautilus, and it works, but it doesn’t give me the result I want, most applications don’t see the folder, while others can. Also I am open to options other than FTP if anyone has any suggestions. I've looked into FreeNAS but that doesn’t seem to allow me to control the user accounts the way I want to. Then after all is said and done I would still need a way to mount the shares as a drive in Ubuntu. The ability to mount network drives in windows is one of my favourite features, but seeing how Ubuntu is now my daily OS and has been for about 4 years, I really need a way to accomplish the same thing in Ubuntu. Also a GUI would be preferable, seeing as there will be multiple people using this server, I would like it to be as easy as possible. EDIT: this link here seems to be almost exactly what I'm wanting to do, if I could find a GUI that can do this ill be almost set. then I would just need to find a way to hide specific folders from certain users.

  • RequireJS: JavaScript for the Enterprise

    - by Geertjan
    I made a small introduction to RequireJS via some of the many cool new RequireJS features in NetBeans IDE. I believe RequireJS, and the modularity and encapsulation and loading solutions that it brings, provides the tools needed for creating large JavaScript applications, i.e., enterprise JavaScript applications. &amp;amp;lt;span id=&amp;amp;quot;XinhaEditingPostion&amp;amp;quot;&amp;amp;gt;&amp;amp;lt;/span&amp;amp;gt; (Sorry for the wobbly sound in the above.) An interesting comment by my colleague John Brock on the above: One other advantage that RequireJS brings, is called lazy loading of resources. In your first example, everyone one of those .js files is loaded when the first file is loaded in the browser. By using the require() call in your modules, your application will only load the javascript modules when they are actually needed. It makes for faster startup in large applications. You could show this by showing the libraries that are loaded in the Network Monitor window. So I did as suggested: Click the screenshot to enlarge it and notice how the Network Monitor is helpful in the context of RequireJS troubleshooting.

  • State Changes in a Component Based Architecture [closed]

    - by Maxem
    I'm currently working on a game and using the naive component based architecture thingie (Entities are a bag of components, entity.Update() calls Update on each updateable component), while the addition of new features is really simple, it makes a few things really difficult: a) multithreading / currency b) networking c) unit testing. Multithreading / Concurrency is difficult because I basically have to do poor mans concurrency (running the entity updates in separate threads while locking only stuff that crashes (like lists) and ignoring the staleness of read state (some states are already updated, others aren't)) Networking: There are no explicit state changes that I could efficiently push over the net. Unit testing: All updates may or may not conflict, so automated testing is at least awkward. I was thinking about these issues a bit and would like your input on these changes / idea: Switch from the naive cba to a cba with sub systems that work on lists of components Make all state changes explicit Combine 1 and 2 :p Example world update: statePostProcessing.Wait() // ensure that post processing has finished Apply(postProcessedState) state = new StateBag() Concurrently( () => LifeCycleSubSystem.Update(state), // populates the state bag () => MovementSubSystem.Update(state), // populates the state bag .... }) statePostProcessing = Future(() => PostProcess(state)) statePostProcessing.Start() // Tick is finished, the post processing happens in the background So basically the changes are (consistently) based on the data for the last tick; the post processing can a) generate network packages and b) fix conflicts / remove useless changes (example: entity has been destroyed - ignore movement etc.). EDIT: To clarify the granularity of the state changes: If I save these post processed state bags and apply them to an empty world, I see exactly what has happened in the game these state bags originated from - "Free" replay capability. EDIT2: I guess I should have used the term Event instead of State Change and point out that I kind of want to use the Event Sourcing pattern

  • Will we be penalized for having multiple external links to the same site?

    - by merk
    There seem to be conflicting answers on this question. The most relevant ones seem to be at least a year or two old, so I thought it would be worth re-asking this question. My gut says it's ok, because there are plenty of sites out there that do this already. Every major retailer site usually has links to the manufacturer of whatever item they are selling. go to www.newegg.com and they have hundreds of links to the same site since they sell multiple items from the same brand. Our site allows people to list a specific genre of items for sale (not porn - i'm just keeping it generic since I'm not trying to advertise) and on each item listing page, we have a link back to their website if they want. Our SEO guy is saying this is really bad and google is going to treat us as a link farm. My gut says when we have to start limiting user useful features to our site to boost our ranking, then something is wrong. Or start jumping through hoops by trying to hide text using javascript etc Some clients are only selling 1 to a handful of items, while a couple of our bigger clients have hundreds of items listed so will have hundreds of pages that link back to their site. I should also mention, there will be a handful of pages with the bigger clients where it may appear they have duplicate pages, because they will be selling 2 or 3 of the same item, and the only difference in the content of the page might just be a stock #. The majority of the pages though will have unique content. So - will we be penalized in some way for having anywhere from a handful to a few hundred pages that all point to the same link? If we are penalized, what's the suggested way to handle this? We still want to give users the option to go to the clients site, and we would still like to give a link back to the clients site to help their own SE rankings.

  • Setting up a LAMP VM server for Development and Testing?

    - by TdotThomas
    Info: I would like to set up a VM server on my local computer which will serve pages in the exact same way as my current hosting (but only to me on my local computer). I currently pay a big web hosting company to host my website & web store and they are doing a great job, but I would like to be able to work on my Web site and its corresponding MySQL DB, HTML, and PHP code without being at risk of messing something completely up on the live servers. My current plan of action: Set up a VM webserver with Debian, MySQL, PHP, Apache. Copy web store (PHP/HTML) code to VM server. Copy my current MySQL databases from my hosting provider and install on VM server. Modify and test new features on VM server. Upload MySQL DB and HTML/PHP code back to web host's server where it should work as before but with new modifications. Questions: Now I'm pretty sure I have steps one and two down correctly but I can't for the life of me figure out how to proceed next, so here are my questions. I have my /etc/host file set up so www.MySite.test redirects to the IP address of the local VM webserver. Once I import my PHP/HTML files and MySQL file whats the best way to navigate around the fact that all of my files and DBs will reference www.MySite.com. I can export my MySQL dbs but do I also have to export my MySQL users and passwords to access those db or are those coded into my html/php code?

  • Classes as a compilation unit

    - by Yannbane
    If "compilation unit" is unclear, please refer to this. However, what I mean by it will be clear from the context. Edit: my language allows for multiple inheritance, unlike Java. I've started designing+developing my own programming language for educational, recreational, and potentially useful purposes. At first, I've decided to base it off Java. This implied that I would have all the code be written inside classes, and that code compiles to classes, which are loaded by the VM. However, I've excluded features such as interfaces and abstract classes, because I found no need for them. They seemed to be enforcing a paradigm, and I'd like my language not to do that. I wanted to keep the classes as the compilation unit though, because it seemed convenient to implement, familiar, and I just liked the idea. Then I noticed that I'm basically left with a glorified module system, where classes could be used either as "namespaces", providing constants and functions using the static directive, or as templates for objects that need to be instantiated ("actual" purpose of classes in other languages). Now I'm left wondering: what are the benefits of having classes as compilation units? (Also, any general commentary on my design would be much appreciated.)

  • StreamInsight V2.0 Released!

    - by Roman Schindlauer
    The StreamInsight Team is proud to announce the release of StreamInsight V2.0! This is the version that ships with SQL 2012, and as such it has been available through Connect to SQL CTP customers already since December. As part of the SQL 2012 launch activities, we are now making V2.0 available to everyone, following our tradition of providing a separate download page. StreamInsight V2.0 includes a number of stability and performance fixes over its predecessor V1.2. Moreover it introduces a dependency on the .NET Framework 4.0, as well as on SQL 2012 license keys. For these reasons, we decided to bump the major version number, even though V2.0 does not add new features or API surface. It can be regarded a stepping stone to the upcoming release 2.1 which will contain significantly new APIs (that will depend on .NET 4.0). Head over here to download StreamInsight V2.0. The updated Books Online can be found here. Update: For instructions on how to make your existing application work against the new bits without recompilation, see here. Regards, The StreamInsight Team

  • The Freemium-Premium Puzzle

    The more time I spend thinking about the value of information, the more I found that digitalizing information significantly changed the 'information markets', potentially in an irreversible manner. The graph at the bottom outlines my current view. The existing business models tend to be the same in the digital and analogue information world, i.e. revenue is derived from a combination of consumers' payments and advertisement. Even monetizing 'meta-information' such as search engines isn't new. Just think of the once popular 'Who'sWho'. What really changed is the price-value ratio. The curve is pushed down, closer to the axis. You pay less for the same, or often even get more for less. If you recall the capabilities I described in relevance of information you will see that there are many additional features available for digital content compared to analogue content. I think this is a good 'blue ocean strategy' by combining existing capabilities in a new way. (Kim W.C. & Mauborgne, R. (2005) Blue Ocean Strategies. Boston: Harvard Business School Publishing.). In addition the different channels of digital information distribution significantly change the value of information. I will touch on this in one of my next blogs. Right now, many information providers started to offer 'freemium' content through digital channels, hoping to get a premium for the 'full' content. No freemium seems to take them out of business, because they are apparently no longer visible in today's most relevant channels of information consumption. But, the more freemium is provided, the lower the premium gets; a truly puzzling situation. To make it worse, channel providers increasingly regard information as a value adding and differentiating activity. Maybe new types of exclusive, strategic alliances will solve the puzzle, introducing new types of 'gate-keepers', which - to me - somehow does not match the spirit of the WWW and the generation Y's perception of information consumption and exchange.

  • Javascript Event in Innerhtml Resulting from PHP Server Script

    - by user144527
    I'm (very slowly) making a website, and I'm creating a search engine for the database, which is essential to organize the dependencies during data entry. Anyway, what I would like is to type a few keywords into a box, have a menu pop up with various search results, and have the box fill with the ID number of the selected entry when it's clicked. Currently, I have a document called search.php which fills a div called search-output using xmlhttp.open() and the innerhtml property. Everything is working perfectly except for filling the original search box with the ID number when clicking. My first attempt was to add an onclick event to each entry in the output from search.php. Unfortunately, I found that javascript inserted into innerhtml is not run for security reasons. I've been Googling for hours but haven't been able to find a solution. How can I get the original search text box to fill with the correct ID when I click it? Is what I'm doing a good setup for the results I desire, or is there a better way to integrate search features into data entry?

  • What are the memory-management capabilities of MySQL + JDBC (in light of autonomic computing)?

    - by Adel
    I'm interested in implementing some kind of autonomic-computing functionality using MySQL. By autonomic-computing I mean roughly some failsafe abilities, whereby the application appears to be at least slightly "intelligent" For reference, the main parts of autonomic computing we'd like are the "self-configuring" and "self-healing" features (the other two - "self-optimizing" and "self-protecting", are too abstract/futuristic for us, at this time). Sofor example, if we have a sample Java application that utilizes a MySQL database, we might want to automatically restart the MySQL database if we take up too much memory. Or maybe we want to have the ability to dynamiccally adjust the database memory as needed. So for example, when we start the application the database begins with a 56 Megabyte buffer; but then as we insert so many rows we want to have it automatically jump up to 512 MB, then to 1024, until a max of 4096 MB. Does all of the above suggest that MySQL is too "weak" for the task? Do you suggest using Oracle database? My professor believes that by using Java we can basically make up for any memory-management deficiencies that MySQL has in relation to Oracle DB. I'm new to MySQL , but have experience with Oracle. If all of the above sounds wishy-washy, it is because I'm still fleshing it out. thanks

  • Gesture Based NetBeans Tip Infrastructure

    - by Geertjan
    All/most/many gestures you make in NetBeans IDE are recorded in an XML file in your user directory, "var/log/uigestures", which is what makes the Key Promoter I outlined yesterday possible. The idea behind it is for analysis to be made possible, when you periodically pass the gestures data back to the NetBeans team. See http://statistics.netbeans.org for details. Since the gestures in the 'uigestures' file are identifiable by distinct loggers and other parameters, there's no end to the interesting things that one is able to do with it. While the NetBeans team can see which gestures are done most frequently, e.g., which kinds of projects are created most often, thus helping in prioritizing new features and bugs, etc, you as the user can, depending on who and how the initiative is taken, directly benefit from your collected data, too. Tim Boudreau, in a recent article, mentioned the usefulness of hippie completion. So, imagine that whenever you use code completion, a tip were to appear reminding you about hippie completion. And then you'd be able to choose whether you'd like to see the tip again or not, etc, i.e., customize the frequency of tips and the types of tips you'd like to be shown. And then, it could be taken a step further. The tip plugin could be set up in such a way that anyone would be able to register new tips per gesture. For example, maybe you have something very interesting to share about code completion in NetBeans. So, you'd create your own plugin in which there'd be an HTML file containing the text you'd like to have displayed whenever you (or your team members, or your students, maybe?) use code completion. Then you'd register that HTML file in plugin's layer file, in a subfolder dedicated to the specific gesture that you're interested in commenting on. The same is true, not just for NetBeans IDE, but for anyone creating their applications on top of the NetBeans Platform, of course.

  • Git Branch Model for iOS projects with one developer

    - by glenwayguy
    I'm using git for an iOS project, and so far have the following branch model: feature_brach(usually multiple) -> development -> testing -> master Feature-branches are short-lived, just used to add a feature or bug, then merged back in to development and deleted. Development is fairly stable, but not ready for production. Testing is when we have a stable version with enough features for a new update, and we ship to beta testers. Once testing is finished, it can be moved back into development or advanced into master. The problem, however, lies in the fact that we can't instantly deploy. On iOS, it can be several weeks between the time a build is released and when it actually hits users. I always want to have a version of the code that is currently on the market in my repo, but I also have to have a place to keep the current stable code to be sent for release. So: where should I keep stable code where should I keep the code currently on the market and where should I keep the code that is in review with Apple, and will be (hopefully) put on the market soon? Also, this is a one developer team, so collaboration is not totally necessary, but preferred because there may be more members in the future.

  • Avoiding bloated Domain Objects

    - by djcredo
    We're trying to move data from our bloated Service layer into our Domain layer using a DDD approach. We currently have a lot of business logic in our services, which is spread out all over the place and doesn't benefit from inheritance. We have a central Domain class which is the focus of most of our work - a Trade. The Trade object will know how to price itself, how to estimate risk, validate itself, etc. We can then replace conditionals with polymorphism. Eg: SimpleTrade will price itself one way, but ComplexTrade will price itself another. However, we are worried that this will bloat the Trade class(s). It really should be in charge of its own processing but the class size is going to increase exponentially as more features are added. So we have choices: Put processing logic in Trade class. Processing logic is now polymorphic based on the type of the trade, but Trade class is now has multiple responsibilites (pricing, risk, etc) and is large Put processing logic into other class such as TradePricingService. No longer polymorphic with the Trade inheritance tree, but classes are smaller and easier to test. What would be the suggested approach?
