  • How to prevent WLAN connection from dropping permanently on a Fritz USB WLAN N stick?

    - by Chris
    I have a desktop with a Fritz USB WLAN N stick and tried Ubuntu 12.04. Installation went fine and WLAN is working. However, connection drops permanent. Reconnecting manually fixes it but after a few minutes it drops again. It's connected to a Vodafone 802 box with WLAN N fix set. It seems that it works when I switch off N mode. But I need to test. Can someone confirm this issue or is there another solution? I have another machine with 12.04 (HP 625 laptop) running where connection is stable.

  • 5 Android Keyboard Replacements to Help You Type Faster

    - by Chris Hoffman
    Android allows developers to replace its keyboard with their own keyboard apps. This has led to experimentation and great new features, like the gesture-typing feature that’s made its way into Android’s official keyboard after proving itself in third-party keyboards. This sort of customization isn’t possible on Apple’s iOS or even Microsoft’s modern Windows environments. Installing a third-party keyboard is easy — install it from Google Play, launch it like another app, and it will explain how to enable it. Google Keyboard Google Keyboard is Android’s official keyboard, as seen on Google’s Nexus devices. However, there’s a good chance your Android smartphone or tablet comes with a keyboard designed by its manufacturer instead. You can install the Google Keyboard from Google Play, even if your device doesn’t come with it. This keyboard offers a wide variety of features, including a built-in gesture-typing feature, as popularized by Swype. It also offers prediction, including full next-word prediction based on your previous word, and includes voice recognition that works offline on modern versions of Android. Google’s keyboard may not offer the most accurate swiping feature or the best autocorrection, but it’s a great keyboard that feels like it belongs in Android. SwiftKey SwiftKey costs $4, although you can try it free for one month. In spite of its price, many people who rarely buy apps have been sold on SwiftKey. It offers amazing auto-correction and word-prediction features. Just mash away on your touch-screen keyboard, typing as fast as possible, and SwiftKey will notice your mistakes and type what you actually meant to type. SwiftKey also now has built-in support for gesture-typing via SwiftKey Flow, so you get a lot of flexibility. At $4, SwiftKey may seem a bit pricey, but give the month-long trial a try. A great keyboard makes all the typing you do everywhere on your phone better. SwiftKey is an amazing keyboard if you tap-to-type rather than swipe-to-type. Swype While other keyboards have copied Swype’s swipe-to-type feature, none have completely matched its accuracy. Swype has been designing a gesture-typing keyboard for longer than anyone else and its gesture feature still seems more accurate than its competitors’ gesture support. If you use gesture-typing all the time, you’ll probably want to use Swype. Swype can now be installed directly from Google Play without the old, tedious process of registering a beta account and sideloading the Swype app. Swype offers a month-long free trial and the full version is available for $1 afterwards. Minuum Minuum is a crowdfunded keyboard that is currently still in beta and only supports English. We include it here because it’s so interesting — it’s a great example of the kind of creativity and experimentation that happens when you allow developers to experiment with their own forms of keyboard. Minuum uses a tiny, minimum keyboard that frees up your screen space, so your touch-screen keyboard doesn’t hog your device’s screen. Rather than displaying a full keyboard on your screen, Minuum displays a single row of letters.  Each letter is small and may be difficult to hit, but that doesn’t matter — Minuum’s smart autocorrection algorithms interpret what you intended to type rather than typing the exact letters you press. Just swipe to the right to type a space and accept Minuum’s suggestion. At $4 for a beta version with no trial, Minuum may seem a bit pricy. But it’s a great example of the flexibility Android allows. If there’s a problem with this keyboard, it’s that it’s a bit late — in an age of 5″ smartphones with 1080p screens, full-size keyboards no longer feel as cramped. MessagEase MessagEase is another example of a new take on text input. Thankfully, this keyboard is available for free. MessagEase presents all letters in a nine-button grid. To type a common letter, you’d tap the button. To type an uncommon letter, you’d tap the button, hold down, and swipe in the appropriate direction. This gives you large buttons that can work well as touch targets, especially when typing with one hand. Like any other unique twist on a traditional keyboard, you’d have to give it a few minutes to get used to where the letters are and the new way it works. After giving it some practice, you may find this is a faster way to type on a touch-screen — especially with one hand, as the targets are so large. Google Play is full of replacement keyboards for Android phones and tablets. Keyboards are just another type of app that you can swap in. Leave a comment if you’ve found another great keyboard that you prefer using. Image Credit: Cheon Fong Liew on Flickr

  • We have moved to larger offices

    - by Chris Houston
    First of all we should probably apologise for the complete lack of blogging over the last 6 months! As web developers we are constantly telling our clients that they should keep their blogs up to date and it seems we have been ignoring our own advice.That being said, we have been very busy moving offices and helping our new host QV Offices setup their new business. As well as all the moving we have not been sitting on our hands, we have built the new site for DairyMaster over in Ireland as well as a separate private website for their global distributor network.As Umbraco Gold Partners we have found more and more that we are working on projects where we are the silent development partners, so although we cannot talk publicly about a lot of the sites we develop, we have some real beauties now in our portfolio :)Now that the dust has settled in our new office ( and has been hovered up! ) we are read for the new year and are looking forward to working on some exciting projects that are currently in the pipeline.We are also intending to run some Hacking sessions for Umbraco as we now have lots of space for developers to come and work with us, so if you have any ideas of a theme for an Umbraco Hackathon then do let us know.And with that it just remains to say Happy Christmas to you all and see you in the new year!

  • How to Fix a Stuck Pixel on an LCD Monitor

    - by Chris Hoffman
    Have you ever noticed that a pixel – a little dot on your computer’s LCD monitor – is staying a single color all of the time? You have a stuck pixel. Luckily, stuck pixels aren’t always permanent. Stuck and dead pixels are hardware problems. They’re often caused by manufacturing flaws – pixels aren’t supposed to get stuck or die over time.

  • Antenna Aligner Part 7: Connecting the dots

    - by Chris George
    The app is basically ready, so I eagerly started to sort out creating the application entry in iTunes Connect. It's mostly intuitive actually, although I did have to create yet another icon for iTunes sized 512x512 pixels, damn lucky I did the original graphics as vector! It took me longer to write the application description than anything else, I'm so not a tech author! I didn't like the way you have to 'make up' an SKU (Stock Keeping Unit) number. I have to do some googling to find out that it really doesn't matter what it is! It should be more obvious what to do from the actual website itself. That aside, the rest of it was actually fairly straightforward. As well as the details of the application, iPhone and iPad screenshots were also required. This posed somewhat of a problem. The iPhone ones were easy (as I have one!), but I do not (yet) own an iPad . So I thought I'd leave the iPad screenshots out for now. Once the application details were sorted, I moved onto the rights and pricing. At the start of the project I had made the decision that I wouldn't charge any more than the lowest amount £0.59. I believe there is a market for this, but as my first foray into app development I didn't want to take the mick. I did realise, however, that I had built my app with a developer certificate and provisioning profile. This was fairly quickly corrected, and again Nomad made this very easy to switch over to the distribution certificate and provisioning profile. With a sense of excitement I cracked open iTunes connect and clicked the upload button ... ...slight snag... . when the Nomad project was started, Apple allowed uploads of these binaries via iTunes Connect. But this is no longer possible, the only upload path is via the Application Loader available from the Apple Developer program. This itself has one limitation, it only runs on a mac! D'OH!!!  Actually my language was somewhat more colourful when this fact came to light. After picking my laptop up off the floor and putting it back together... ok only joking, but I did nearly throw it out of frustration!... I started to consider the options; I briefly entertained the idea of buying a cheap mac from ebay... no, that defeats the whole object of what I'm doing, plus my wife wouldn't be impressed there are some guys out there in the interweb who will upload your app for a small fee...but I don't really like the idea of giving some faceless email address my apple developer login details, as well as my app binary! find some willing friend with a mac who would kindly let me use it... obviously this is the only sensible option. In the meantime, I informed the Nomad team about this slight 'issue' and they are currently investigating possible solutions...

  • HTG Explains: Why Do Hard Drives Show the Wrong Capacity in Windows?

    - by Chris Hoffman
    If you’ve ever purchased a computer with a hard disk capacity of 500 GB and opened Windows Explorer only to find that its capacity looked more like 440 GB, you may be wondering where all those gigabytes went. There are several reasons Windows could display the wrong amount of available space, from invisible shadow files, formatting overhead, and hidden recovery partitions to misleading (though technically accurate) storage capacities advertised by hard drive manufacturers.

  • Solution for developers wanting to run a standalone WLS 10.3.6 server against JDev 11.1.1.6.0

    - by Chris Muir
    In my previous post I discussed how to install the 11.1.1.6.0 ADF Runtimes into a standalone WLS 10.3.6 server by using the ADF Runtime installer, not the JDeveloper installer.  Yet there's still a problem for developers here because JDeveloper 11.1.1.6.0 comes coupled with a WLS 10.3.5 server.  What if you want to develop, deploy and test with a 10.3.6 server?  Have we lost the ability to integrate the IDE and the WLS server where we can run and stop the server, deploy our apps automatically the server and more? JDeveloper actually solved this issue sometime back but not many people will have recognized the feature for what it does as it wasn't needed until now. Via the Application Server Navigator you can create 2 types of connections, one to a remote "standalone WLS" and another to an "integrated WLS".  It's this second option that is useful because what we can do is install a local standalone WLS 10.3.6 server on our developer PC, then create a separate "integrated WLS" connection to the standalone server.  Then by accessing your Application's properties through the Application menu -> Application Properties -> Run -> Bind to Integration Application Server option we can choose the newly created WLS server connection to work with our application. In this way JDeveloper will now treat the new server as if it was the integrated WLS.  It will start when we run and deploy our applications, terminate it at request and so on.  Of course don't forget you still need to install the ADF Runtimes for the server to be able to work with ADF applications. Note there is bug 13917844 lurking in the Application Server Navigator for at least JDev 11.1.1.6.0 and earlier.  If you right click the new connection and select "Start Server Instance" it will often start one of the other existing connections instead (typically the original IntegratedWebLogicServer connection).  If you want to manually start the server you can bypass this by using the Run menu -> Start Server Instance option which works correctly.

  • Why does 'top' say my machine is only 50% idle?

  • Antenna Aligner Part 4: Role'ing in the deep

    - by Chris George
    Since last time I've been trying to sort out the general workflow of the app. It's fundamentally not hard, there is a list of transmitters, you select a transmitter and it shows the compass view. Having done quite a bit of ajax/asp.net/html in the past, I immediately started off by creating two divs within my 'page', one for the list, one for the compass. Then using the onClick event in the list, this will switch the display attribute on the divs. This seemed to work, but did lead to some dodgy transitional redrawing artefacts which I was not happy with. So after some Googling I realised I was doing it all wrong! JQuery mobile has the concept of giving an object in html a data-role. By giving a div the attribute data-role="page" it is then treated as a separate page on the mobile device. Within the code, this is referenced like a html anchor in the form #mypage. Using this system, page transitions such as fade or slide are automatically applied which adds to the whole authenticity of the app! Here is a simple example: . <a href="#'compasspage">compass</a> . <div data-role="page" id="compasspage" data-add-back-btn="true"> But I don't want just a static link, I want to dynamically create my list, and get each list elements to switch to the compass page with the right information. So here is the jquery that I used to dynamically inject new <li> rows into the <ul> block. $('ul').append($('<li/>', {    //here appendin `<li>`     'data-role': "list-divider" }).append($('<a/>', {    //here appending `<a>` into `<li>`     'href': '#compasspage',     'data-transition': 'none',     'onclick': 'selectTx(' + i + ')',     'html': buttonHtml }))); $('ul').listview('refresh'); This is called within a for loop so the first 5 appropriate transmitters are used. There are several things of interest to note here. Firstly, I could not find a more elegant way to tell the target page which transmitter I've clicked on, so I have used the onclick event as well as the href attribute. The onclick event fires 'selectTx' which simply sets a global member variable to the specific index number I've clicked on. Yes it's not nice, but it works. Secondly, the data-transition attribute is set to 'none'. I wanted the transition between the pages to be a whooshy slidey effect. However this worked going to the compass page, but returning to the list page gave some undesirable visual artefacts (flickering, redrawing etc.). So I decided to remove the transitions all together, which was a shame. Thirdly, rather than embedding loads of html into the append command, I removed this out into a variable 'buttonHtml'. Doing this really tidied up my code. Until next time!

  • HTG Explains: What is the Windows Page File and Should You Disable It?

    - by Chris Hoffman
    Windows uses a page file to store data that can’t be held by your computer’s random-access memory when it fills up. While you can tweak the page file settings, Windows can manage the page file fine on its own. The Windows page file is somewhat misunderstood. People see it as the cause of slowdowns because it’s slower to use the page file than your computer’s RAM, but having a page file is better than not having one.

  • why would Remmina stop working?

    - by Chris Curvey
    Until sometime last night, I had remmina working fine. I could run RDP through an SSH tunnel and all was well. Then it stopped working. I can get as far as the password dialog for my work machine, but then it just says "Cannot connect to RDP server localhost". I can't even find any logs that look interesting. I've re-installed remmina, cleared my .remmina directory, restarted my machine, and even restarted my gateway. Just to make it really weird, my laptop (which has the same setup -- latest Ubuntu and Remmina) can make the connection just fine. It is even going through the same router, albeit wirelessly. Any thoughts?

  • Web.NET event coming in October

    - by Chris Massey
    If you’re a web developer in Europe (or would like an excuse to travel to Europe), you should definitely take a look at the Web.NET event coming in October. It’s being organized by two Italian web maestros (Simone Chiaretta and Ugo Lattanzi) and the session list looks fantastic. The event site pretty much speaks for itself, but here’s a quick version: It’s a free one-day event on October 20th, with a huge variety of great sessions by great speakers, all 100% focused on web development. There’s a pizza-fuelled hackathon in the evening; thrills, spills and hot new skills. It’s a great chance to network with the local (in relative terms) web development community. It’s free (although all donations are very greatly appreciated). It’s in Milan, darling. Here’s what you need to do: Go and register on www.webnetconf.eu, and vote on which sessions you think look the most interesting. I know this will be a difficult process – it’s *very* hard to choose – but persevere! Grab your place when the free tickets become available early next month (places are limited). Come to Milan in October, learn some new skills, meet some great people, and maybe build something awesome if you feel like staying up late. I’ll be there, and hopefully I’ll see you on the day.

  • Coordinate based travel through multi-line path over elapsed time

    - by Chris
    I have implemented A* Path finding to decide the course of a sprite through multiple waypoints. I have done this for point A to point B locations but am having trouble with multiple waypoints, because on slower devices when the FPS slows and the sprite travels PAST a waypoint I am lost as to the math to switch directions at the proper place. EDIT: To clarify my path finding code is separate in a game thread, this onUpdate method lives in a sprite like class which happens in the UI thread for sprite updating. To be even more clear the path is only updated when objects block the map, at any given point the current path could change but that should not affect the design of the algorithm if I am not mistaken. I do believe all components involved are well designed and accurate, aside from this piece :- ) Here is the scenario: public void onUpdate(float pSecondsElapsed) { // this could be 4x speed, so on slow devices the travel moved between // frames could be very large. What happens with my original algorithm // is it will start actually doing circles around the next waypoint.. pSecondsElapsed *= SomeSpeedModificationValue; final int spriteCurrentX = this.getX(); final int spriteCurrentY = this.getY(); // getCoords contains a large array of the coordinates to each waypoint. // A waypoint is a destination on the map, defined by tile column/row. The // path finder converts these waypoints to X,Y coords. // // I.E: // Given a set of waypoints of 0,0 to 12,23 to 23, 0 on a 23x23 tile map, each tile // being 32x32 pixels. This would translate in the path finder to this: // -> 0,0 to 12,23 // Coord : x=16 y=16 // Coord : x=16 y=48 // Coord : x=16 y=80 // ... // Coord : x=336 y=688 // Coord : x=336 y=720 // Coord : x=368 y=720 // // -> 12,23 to 23,0 -NOTE This direction change gives me trouble specifically // Coord : x=400 y=752 // Coord : x=400 y=720 // Coord : x=400 y=688 // ... // Coord : x=688 y=16 // Coord : x=688 y=0 // Coord : x=720 y=0 // // The current update index, the index specifies the coordinate that you see above // I.E. final int[] coords = getCoords( 2 ); -> x=16 y=80 final int[] coords = getCoords( ... ); // now I have the coords, how do I detect where to set the position? The tricky part // for me is when a direction changes, how do I calculate based on the elapsed time // how far to go up the new direction... I just can't wrap my head around this. this.setPosition(newX, newY); }

  • How to Comment Out and Uncomment Lines in a Configuration File

    - by Chris Hoffman
    You may have seen instructions that tell you to “uncomment” or “comment out” lines in a configuration or source code file. This is a simple process, but may not be self-explanatory to people that don’t understand the file’s structure.

  • How to get tens of millions of pages indexed by Google bot?

    - by Chris Adragna
    We are currently developing a site that currently has 8 million unique pages that will grow to about 20 million right away, and eventually to about 50 million or more. Before you criticize... Yes, it provides unique, useful content. We continually process raw data from public records and by doing some data scrubbing, entity rollups, and relationship mapping, we've been able to generate quality content, developing a site that's quite useful and also unique, in part due to the breadth of the data. It's PR is 0 (new domain, no links), and we're getting spidered at a rate of about 500 pages per day, putting us at about 30,000 pages indexed thus far. At this rate, it would take over 400 years to index all of our data. I have two questions: Is the rate of the indexing directly correlated to PR, and by that I mean is it correlated enough that by purchasing an old domain with good PR will get us to a workable indexing rate (in the neighborhood of 100,000 pages per day). Are there any SEO consultants who specialize in aiding the indexing process itself. We're otherwise doing very well with SEO, on-page especially, besides, the competition for our "long-tail" keyword phrases is pretty low, so our success hinges mostly on the number of pages indexed. Our main competitor has achieved approx 20MM pages indexed in just over one year's time, along with an Alexa 2000-ish ranking. Noteworthy qualities we have in place: page download speed is pretty good (250-500 ms) no errors (no 404 or 500 errors when getting spidered) we use Google webmaster tools and login daily friendly URLs in place I'm afraid to submit sitemaps. Some SEO community postings suggest a new site with millions of pages and no PR is suspicious. There is a Google video of Matt Cutts speaking of a staged on-boarding of large sites, too, in order to avoid increased scrutiny (at approx 2:30 in the video). Clickable site links deliver all pages, no more than four pages deep and typically no more than 250(-ish) internal links on a page. Anchor text for internal links is logical and adds relevance hierarchically to the data on the detail pages. We had previously set the crawl rate to the highest on webmaster tools (only about a page every two seconds, max). I recently turned it back to "let Google decide" which is what is advised.

  • Is this Ubuntu One DBus signal connection code correct?

    - by Chris Wilson
    This is my first time using DBus so I'm not entirely sure if I'm going about this the right way. I'm attempting to connect the the Ubuntu One DBus service and obtain login credentials for my app, however the slots I've connected to the DBus return signals detailed here never seem to be firing, despite a positive result being returned during the connection. Before I start looking for errors in the details relating to this specific service, could someone please tell me if this code would even work in the first place, or if I'm done something wrong here? int main() { UbuntuOneDBus *u1Dbus = new UbuntuOneDBus; if( u1Dbus->init() ){ qDebug() << "Message queued"; } } UbuntuOneDBus::UbuntuOneDBus() { service = "com.ubuntuone.Credentials"; path = "/credentials"; interface = "com.ubuntuone.CredentialsManagement"; method = "register"; signature = "a{ss} (Dict of {String, String})"; connectReturnSignals(); } bool UbuntuOneDBus::init() { QDBusMessage message = QDBusMessage::createMethodCall( service, path, interface, method ); bool queued = QDBusConnection::sessionBus().send( message ); return queued; } void UbuntuOneDBus::connectReturnSignals() { bool connectionSuccessful = false; connectionSuccessful = QDBusConnection::sessionBus().connect( service, path, interface, "CredentialsFound", "a{ss} (Dict of {String, String})", this, SLOT( credentialsFound() ) ); if( ! connectionSuccessful ) qDebug() << "Connection to DBus::CredentialsFound signal failed"; connectionSuccessful = QDBusConnection::systemBus().connect( service, path, interface, "CredentialsNotFound", "(nothing)", this, SLOT( credentialsNotFound() ) ); if( ! connectionSuccessful ) qDebug() << "Connection to DBus::CredentialsNotFound signal failed"; connectionSuccessful = QDBusConnection::systemBus().connect( service, path, interface, "CredentialsError", "a{ss} (Dict of {String, String})", this, SLOT( credential if( ! connectionSuccessful ) qDebug() << "Connection to DBus::CredentialsError signal failed"; } void UbuntuOneDBus::credentialsFound() { std::cout << "Credentials found" << std::endl; } void UbuntuOneDBus::credentialsNotFound() { std::cout << "Credentials not found" << std::endl; } void UbuntuOneDBus::credentialsError() { std::cout << "Credentials error" << std::endl; }

  • How To Log Into Multiple Accounts On the Same Website At Once

    - by Chris Hoffman
    If you ever want to sign into two different accounts on the same website at once – say, to have multiple Gmail inboxes open next to each other – you can’t just open a new tab or browser window. Websites store your login state in browser-specific cookies. There are a number of ways you can get another browser window with its own cookies and stay logged into multiple accounts at once.
