  • AGENT: The World's Smartest Watch

    - by Rob Chartier
    AGENT: The World's Smartest Watch by Secret Labs + House of Horology Disclaimer: Most if not all of this content has been gleaned from the comments on the Kickstarter project page and comments section. Any discrepancies between this post and any documentation on agentwatches.com, kickstarter.com, etc.., those official sites take precedence. Overview The next generation smartwatch with brand-new technology. World-class developer tools, unparalleled battery life, Qi wireless charging. Kickstarter Page, Comments Funding period : May 21, 2013 - Jun 20, 2013 MSRP : $249 Other Urls http://www.agentwatches.com/ https://www.facebook.com/agentwatches http://twitter.com/agentwatches http://pinterest.com/agentwatches/ http://paper.li/robchartier/1371234640 Developer Story The first official launch of the preview SDK and emulator will happen on 20-Jun-2013.  All development will be done in Visual Studio 2012, using the .NET Micro Framework SDK 2.3.  The SDK will ship with the first round of the expected API for developers along with an emulator. With that said, there is no need to wait for the SDK.  You can download the tooling now and get started with Apps and Faces immediately.  The only thing that you will not be able to work with is the API; but for example, watch faces, you can start building the basic face rendering with the Bitmap graphics drawing in the .NET Micro Framework.   Does it look good? Before we dig into any more of the gory details, here are a few photos of the current available prototype models.   The watch on the tiny QI Charter   If you wander too far away from your phone, your watch will let you know with a vibration and a message, all but one button will dismiss the message.   An app showing the premium weather data!   Nice stitching on the straps, leather and silicon will be available, along with a few lengths to choose from (short, regular, long lengths). On to those gory details…. Hardware Specs Processor 120MHz ARM Cortex-M4 processor (ATSAM4SD32) with secondary AVR co-processor Flash & RAM 2MB of onboard flash and 160KB of RAM 1/4 of the onboard flash will be used by the OS The flash is permanent (non-volatile) storage. Bluetooth Bluetooth 4.0 BD/EDR + LE Bluetooth 4.0 is backwards compatible with Bluetooth 2.1, so classic Bluetooth functions (BD/EDR, SPP/AVRCP/PBAP/etc.) will work fine. Sensors 3D Accelerometer (Motion) ST LSM303DLHC Ambient Light Sensor Hardware power metering Vibration Motor (You can pulse it to create vibration patterns, not sure about the vibration strength - driven with PWM) No piezo/speaker or microphone. Other QI Wireless Charging, no NFC, no wall adapter included Custom LED Backlight No GPS in the watch. It uses the GPS in your phone. AGENT watch apps are deployed and debugged wirelessly from your PC via Bluetooth. RoHS, Pb-free Battery Expected to use a CR2430-sized rechargeable battery – replaceable (Mouser, Amazon) Estimated charging time from empty is 2 hours with provided charger 7 Days typical with Bluetooth on, 30 days with Bluetooth off (watch-face only mode) The battery should last at least 2 years, with 100s of charge cycles. Physical dimensions Roughly 38mm top-to-bottom on the front face 35mm left-to-right on the front face and around 12mm in depth 22mm strap Two ~1/16" hex screws to attach the watch pin The top watchcase material candidates are PVD stainless steel, brushed matte ceramic, and high-quality polycarbonate (TBD). The glass lens is mineral glass, Anti-glare glass lens Strap options Leather and silicon straps will be available Expected to have three sizes Display 1.28" Sharp Memory Display The display stays on 100% of the time. Dimensions: 128x128 pixels Buttons Custom "Pusher" buttons, they will not make noise like a mouse click, and are very durable. The top-left button activates the backlight; bottom-left changes apps; three buttons on the right are up/select/down and can be used for custom purposes by apps. Backup reset procedure is currently activated by holding the home/menu button and the top-right user button for about ten seconds Device Support Android 2.3 or newer iPhone 4S or newer Windows Phone 8 or newer Heart Rate monitors - Bluetooth SPP or Bluetooth LE (GATT) is what you'll want the heart monitor to support. Almost limitless Bluetooth device support! Internationalization & Localization Full UTF8 Support from the ground up. AGENT's user interface is in English. Your content (caller ID, music tracks, notifications) will be in your native language. We have a plan to cover most major character sets, with Latin characters pre-loaded on the watch. Simplified Chinese will be available Feature overview Phone lost alert Caller ID Music Control (possible volume control) Wireless Charging Timer Stopwatch Vibrating Alarm (possibly custom vibrations for caller id) A few default watch faces Airplane mode (by demand or low power) Can be turned off completely Customizable 3rd party watch faces, applications which can be loaded over bluetooth. Sample apps that maybe installed Weather Sample Apps not installed Exercise App Other Possible Skype integration over Bluetooth. They will provide an AGENT app for your smartphone (iPhone, Android, Windows Phone). You'll be able to use it to load apps onto the watch.. You will be able to cancel phone calls. With compatible phones you can also answer, end, etc. They are adopting the standard hands-free profile to provide these features and caller ID.

  • WCF REST on .Net 4.0

    - by AngelEyes
    A simple and straight forward article taken from: http://christopherdeweese.com/blog2/post/drop-the-soap-wcf-rest-and-pretty-uris-in-net-4 Drop the Soap: WCF, REST, and Pretty URIs in .NET 4 Years ago I was working in libraries when the Web 2.0 revolution began.  One of the things that caught my attention about early start-ups using the AJAX/REST/Web 2.0 model was how nice the URIs were for their applications.  Those were my first impressions of REST; pretty URIs.  Turns out there is a little more to it than that. REST is an architectural style that focuses on resources and structured ways to access those resources via the web.  REST evolved as an “anti-SOAP” movement, driven by developers who did not want to deal with all the complexity SOAP introduces (which is al lot when you don’t have frameworks hiding it all).  One of the biggest benefits to REST is that browsers can talk to rest services directly because REST works using URIs, QueryStrings, Cookies, SSL, and all those HTTP verbs that we don’t have to think about anymore. If you are familiar with ASP.NET MVC then you have been exposed to rest at some level.  MVC is relies heavily on routing to generate consistent and clean URIs.  REST for WCF gives you the same type of feel for your services.  Let’s dive in. WCF REST in .NET 3.5 SP1 and .NET 4 This post will cover WCF REST in .NET 4 which drew heavily from the REST Starter Kit and community feedback.  There is basic REST support in .NET 3.5 SP1 and you can also grab the REST Starter Kit to enable some of the features you’ll find in .NET 4. This post will cover REST in .NET 4 and Visual Studio 2010. Getting Started To get started we’ll create a basic WCF Rest Service Application using the new on-line templates option in VS 2010: When you first install a template you are prompted with this dialog: Dude Where’s my .Svc File? The WCF REST template shows us the new way we can simply build services.  Before we talk about what’s there, let’s look at what is not there: The .Svc File An Interface Contract Dozens of lines of configuration that you have to change to make your service work REST in .NET 4 is greatly simplified and leverages the Web Routing capabilities used in ASP.NET MVC and other parts of the web frameworks.  With REST in .NET 4 you use a global.asax to set the route to your service using the new ServiceRoute class.  From there, the WCF runtime handles dispatching service calls to the methods based on the Uri Templates. global.asax using System; using System.ServiceModel.Activation; using System.Web; using System.Web.Routing; namespace Blog.WcfRest.TimeService {     public class Global : HttpApplication     {         void Application_Start(object sender, EventArgs e)         {             RegisterRoutes();         }         private static void RegisterRoutes()         {             RouteTable.Routes.Add(new ServiceRoute("TimeService",                 new WebServiceHostFactory(), typeof(TimeService)));         }     } } The web.config contains some new structures to support a configuration free deployment.  Note that this is the default config generated with the template.  I did not make any changes to web.config. web.config <?xml version="1.0"?> <configuration>   <system.web>     <compilation debug="true" targetFramework="4.0" />   </system.web>   <system.webServer>     <modules runAllManagedModulesForAllRequests="true">       <add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule,            System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />     </modules>   </system.webServer>   <system.serviceModel>     <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>     <standardEndpoints>       <webHttpEndpoint>         <!--             Configure the WCF REST service base address via the global.asax.cs file and the default endpoint             via the attributes on the <standardEndpoint> element below         -->         <standardEndpoint name="" helpEnabled="true" automaticFormatSelectionEnabled="true"/>       </webHttpEndpoint>     </standardEndpoints>   </system.serviceModel> </configuration> Building the Time Service We’ll create a simple “TimeService” that will return the current time.  Let’s start with the following code: using System; using System.ServiceModel; using System.ServiceModel.Activation; using System.ServiceModel.Web; namespace Blog.WcfRest.TimeService {     [ServiceContract]     [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]     [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]     public class TimeService     {         [WebGet(UriTemplate = "CurrentTime")]         public string CurrentTime()         {             return DateTime.Now.ToString();         }     } } The endpoint for this service will be http://[machinename]:[port]/TimeService.  To get the current time http://[machinename]:[port]/TimeService/CurrentTime will do the trick. The Results Are In Remember That Route In global.asax? Turns out it is pretty important.  When you set the route name, that defines the resource name starting after the host portion of the Uri. Help Pages in WCF 4 Another feature that came from the starter kit are the help pages.  To access the help pages simply append Help to the end of the service’s base Uri. Dropping the Soap Having dabbled with REST in the past and after using Soap for the last few years, the WCF 4 REST support is certainly refreshing.  I’m currently working on some REST implementations in .NET 3.5 and VS 2008 and am looking forward to working on REST in .NET 4 and VS 2010.

  • Ask How-To Geek: Dropbox in the Start Menu, Understanding Symlinks, and Ripping TV Series DVDs

    - by Jason Fitzpatrick
    This week we take a look at how to incorporate Dropbox into your Windows Start Menu, understanding and using symbolic links, and how to rip your TV series DVDs right to unique and high-quality episode files. Once a week we dip into our reader mailbag and help readers solve their problems, sharing the useful solutions with you in the process. Read on to see our fixes for this week’s reader dilemmas. Add Drobox to Your Start Menu Dear How-To Geek, I use Dropbox all the time and would like to add it right onto my start menu along side the other major shortcuts like Documents, Pictures, etc. It seems like adding Dropbox into the menu should be part of the Dropbox installation package! Sincerely, Dropboxing in Des Moines Dear Dropboxing, We agree, it would be a nice installation option. As it stands you’re going to have to do a little simple hacking to get Dropbox nestled neatly into your start menu. The hack isn’t super elegant but when you’re done you’ll have the link you want and it’ll look like it was there all along. Check out this step-by-step guide here in order to take an existing Library shortcut and rework it to be a Dropbox link. Understanding and Using Symbolic Links Dear How-To Geek, I was talking to a coworker the other day about an issue I’d been having with a media center application I’m running. He suggested using symbolic links to better organize my media and make it easier for the application to access my collection. I had no idea what he was talking about and never got a chance to bug him about it later. Can you clear up this whole symbolic links business for me? I’ve been using computers for years and I’ve never even heard of it! Sincerely, Symbolic Who? Dear Symbolic, Symbolic links aren’t commonly used by many Windows users which is why you likely haven’t run into the concept. Symbolic links are essentially supercharged shortcuts—the newly introduced Windows library system is really just a type of symbolic link system. You can use symbolic links to do all sorts of neat stuff like link folders to your Dropbox folder, organize media, and more. The concept of symbolic links is pretty simple but the execution can be really tricky. We’d suggest reading over our guide to creating symbolic links in Windows 7, Windows XP, and Ubunutu to get a clearer idea what you’re getting into. Rip Your TV DVDs into Handy Episode Files Dear How-To Geek, My wife got me an iPod for Christmas and I still haven’t got around to filling it up. I have tons of entire TV show seasons on DVD and would like to get them on the iPod but I have absolutely no idea where to start. How do I get the shows off the discs? I thought it would be as easy to import the TV shows into iTunes as it is to import tracks off a CD but I was totally wrong. I tried downloading some applications to rip them but those didn’t work at all. Very frustrating! Surely there is an easy and/or automated way to do this, right? Sincerely, Free My DVDs Dear DVDs, Oh man is this a frustration we can relate to. It’s inordinately difficult to get movies and TV shows off physical media and into digital (and portable media player-friendly) formats. There are a multitude of ways to rip DVDs and quite a few applications out there (some good, some mediocre, and some outright malware). We’d recommend a two-part punch to solve your ripping woes. You’ll need a copy of DVDFab to strip away the protections on the discs and rip the disc and Handbrake to load the disc image and convert the files. It’s not quite as smooth as the CD-to-iTunes workflow but it’s still pretty easy. Check out all the steps and settings you’ll want to toggle here.

  • MySQL 5.5 - Lost connection to MySQL server during query

    - by bully
    I have an Ubuntu 12.04 LTS server running at a german hoster (virtualized system). # uname -a Linux ... 3.2.0-27-generic #43-Ubuntu SMP Fri Jul 6 14:25:57 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux I want to migrate a Web CMS system, called Contao. It's not my first migration, but my first migration having connection issues with mysql. Migration went successfully, I have the same Contao version running (it's more or less just copy / paste). For the database behind, I did: apt-get install mysql-server phpmyadmin I set a root password and added a user for the CMS which has enough rights on its own database (and only its database) for doing the stuff it has to do. Data import via phpmyadmin worked just fine. I can access the backend of the CMS (which needs to deal with the database already). If I try to access the frontend now, I get the following error: Fatal error: Uncaught exception Exception with message Query error: Lost connection to MySQL server during query (<query statement here, nothing special, just a select>) thrown in /var/www/system/libraries/Database.php on line 686 (Keep in mind: I can access mysql with phpmyadmin and through the backend, working like a charme, it's just the frontend call causing errors). If I spam F5 in my browser I can sometimes even kill the mysql deamon. If I run # mysqld --log-warnings=2 I get this: ... 120921 7:57:31 [Note] mysqld: ready for connections.

It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware.

I already re-installed mysql via: sudo apt-get remove mysql-server mysql-common sudo apt-get autoremove sudo apt-get install mysql-server without any results. This is the first time I'm running into this problem, and I'm not very experienced with this kind of mysql 'administration'. So mainly, I want to know if anyone of you could help me out please :) Is it a mysql bug? Is something broken in the Ubuntu repositories? Is this one of those misterious 'use-tcp-connection-instead-of-socket-stuff-because-there-are-problems-on-virtualized-machines-with-sockets'-problem? Or am I completly on the wrong way and I just miss-configured something? Remember, phpmyadmin and access to the backend (which uses the database, too) is just fine. Maybe something with Apache? What can I do? Any help is appreciated, so thanks in advance :)

  • 8 Things You Can Do In Android’s Developer Options

    - by Chris Hoffman
    The Developer Options menu in Android is a hidden menu with a variety of advanced options. These options are intended for developers, but many of them will be interesting to geeks. You’ll have to perform a secret handshake to enable the Developer Options menu in the Settings screen, as it’s hidden from Android users by default. Follow the simple steps to quickly enable Developer Options. Enable USB Debugging “USB debugging” sounds like an option only an Android developer would need, but it’s probably the most widely used hidden option in Android. USB debugging allows applications on your computer to interface with your Android phone over the USB connection. This is required for a variety of advanced tricks, including rooting an Android phone, unlocking it, installing a custom ROM, or even using a desktop program that captures screenshots of your Android device’s screen. You can also use ADB commands to push and pull files between your device and your computer or create and restore complete local backups of your Android device without rooting. USB debugging can be a security concern, as it gives computers you plug your device into access to your phone. You could plug your device into a malicious USB charging port, which would try to compromise you. That’s why Android forces you to agree to a prompt every time you plug your device into a new computer with USB debugging enabled. Set a Desktop Backup Password If you use the above ADB trick to create local backups of your Android device over USB, you can protect them with a password with the Set a desktop backup password option here. This password encrypts your backups to secure them, so you won’t be able to access them if you forget the password. Disable or Speed Up Animations When you move between apps and screens in Android, you’re spending some of that time looking at animations and waiting for them to go away. You can disable these animations entirely by changing the Window animation scale, Transition animation scale, and Animator duration scale options here. If you like animations but just wish they were faster, you can speed them up. On a fast phone or tablet, this can make switching between apps nearly instant. If you thought your Android phone was speedy before, just try disabling animations and you’ll be surprised how much faster it can seem. Force-Enable FXAA For OpenGL Games If you have a high-end phone or tablet with great graphics performance and you play 3D games on it, there’s a way to make those games look even better. Just go to the Developer Options screen and enable the Force 4x MSAA option. This will force Android to use 4x multisample anti-aliasing in OpenGL ES 2.0 games and other apps. This requires more graphics power and will probably drain your battery a bit faster, but it will improve image quality in some games. This is a bit like force-enabling antialiasing using the NVIDIA Control Panel on a Windows gaming PC. See How Bad Task Killers Are We’ve written before about how task killers are worse than useless on Android. If you use a task killer, you’re just slowing down your system by throwing out cached data and forcing Android to load apps from system storage whenever you open them again. Don’t believe us? Enable the Don’t keep activities option on the Developer options screen and Android will force-close every app you use as soon as you exit it. Enable this app and use your phone normally for a few minutes — you’ll see just how harmful throwing out all that cached data is and how much it will slow down your phone. Don’t actually use this option unless you want to see how bad it is! It will make your phone perform much more slowly — there’s a reason Google has hidden these options away from average users who might accidentally change them. Fake Your GPS Location The Allow mock locations option allows you to set fake GPS locations, tricking Android into thinking you’re at a location where you actually aren’t. Use this option along with an app like Fake GPS location and you can trick your Android device and the apps running on it into thinking you’re at locations where you actually aren’t. How would this be useful? Well, you could fake a GPS check-in at a location without actually going there or confuse your friends in a location-tracking app by seemingly teleporting around the world. Stay Awake While Charging You can use Android’s Daydream Mode to display certain apps while charging your device. If you want to force Android to display a standard Android app that hasn’t been designed for Daydream Mode, you can enable the Stay awake option here. Android will keep your device’s screen on while charging and won’t turn it off. It’s like Daydream Mode, but can support any app and allows users to interact with them. Show Always-On-Top CPU Usage You can view CPU usage data by toggling the Show CPU usage option to On. This information will appear on top of whatever app you’re using. If you’re a Linux user, the three numbers on top probably look familiar — they represent the system load average. From left to right, the numbers represent your system load over the last one, five, and fifteen minutes. This isn’t the kind of thing you’d want enabled most of the time, but it can save you from having to install third-party floating CPU apps if you want to see CPU usage information for some reason. Most of the other options here will only be useful to developers debugging their Android apps. You shouldn’t start changing options you don’t understand. If you want to undo any of these changes, you can quickly erase all your custom options by sliding the switch at the top of the screen to Off.

  • Aamir Khan’s Satyamev Jayate stirs a movement

    - by Gopinath
    Bollywood actor Aamir Khan is known for his dedication and hard work in inspiring millions of viewers though movies by discussing social problems and motivating people to solve them. His movie Rang De Basanthi seeded Indian anti-corruption movement, Tare Zameen Par touched the problems faced by few challenged kids and the latest movie 3 idiots exposed how education institutions in India are producing lakhs of Donkeys out of colleges every year. He extended his dedication of serving the society to small screen with the launch of reality TV show Satyamev Jayate. Before you start misjudging it as one of those non sense drama / entertaining reality shows, let me tell you that it is not a typical music, games, fight or dance reality show. Satyamev Jayate is all about the real people of India, their problems and how to tackle them.  This is not just a reality show, its movement to educate people about the social evils. Its been many years since I spent couple of hours  in front of TV as most of the programs are too cynical or does not add much value.  In my childhood I use to anxiously wait for Mahabarath or He-Man TV shows to start but after a two decades I waited anxiously for the start of Satyamev Jayate. The wait was worth and the 1 hours 30 minutes spent watching it meaningful. When was the last time you were so satisfied after watching a TV show and inspired to do something? I don’t remember. Today, the show focused on female foeticide and its impact. It showed women who were tortured and forced to abort female foetuses. On the show few brave women shared their experiences of giving birth to girl babies and rough times they are going through with their in-laws & husbands. The show not only focused on the problem but also on the root cause of the evil,  inspiring people working to tackle it and what every individual can do his part to solve it.  The best part of the show is,  its not a blame game. When there is a problem most of the people quickly get into identifying who is wrong and start blaming them instead of solve the actual problem.  Aamir did not blame anyone for female foeticide – neither the government who don’t impose strict rules, nor the doctors who abort girl babies to make money or the mother-in-laws & husbands who torcher girl baby mothers are blamed. He careful highlighted the problem, showed horrifying statistics and their impact on the future society and few inspiring people working to tackle the problem.  He touched heart and stirred a movement against the issue. First time ever I voted for a reality show through SMS and it’s for Satyamev Jayate. I’m proud to do so. Here are the few reactions of popular people, activists & media about the program @aamir_khan absolutely the best program I have seen on TV in recent past. Thanku for converting an idiot box into an inspirationsl medium — Kiran Bedi (@thekiranbedi) May 6, 2012 Satyamev Jayate proves tht TV 2 can b a tool of social change. — Shekhar Kapur (@shekharkapur) May 6, 2012 i absolutely loved #satyamevjayate. at least aamir is doing what all of us only talk about. — Harsha Bhogle (@bhogleharsha) May 6, 2012 Now Television will no longer be called an idiot box,the VISION of Television broadens up with#SatyamevJayate !!! — Madhur Bhandarkar (@mbhandarkar268) May 6, 2012 The Sunday 11am slot seems to have come back with a bang… #SatyamevJayate — atul kasbekar (@atulkasbekar) May 6, 2012   I was spellbound, says Prasoon Joshi – It’s a unique show. I was completely bowled over by it. It’s a never-done before concept Aamir Khan strikes the right chord with Satyamev Jayate – The format is quite crisp. Talking about the emotional connect, there are moments when your eyes well up with tears, but the various segments ensure there’s more content than emotional drama ‘Satyamev Jayate’ gutsy, sensible show: Viewers – From filmmakers to clinical psychologists to professors – everyone has given the thumbs up to Aamir Khan’s television show ‘Satyamev Jayate’, saying it is a gutsy, hard-hitting and sensible programme that strikes an emotional chord with the audiences. Aamir Khan’s TV debut ‘Satyamev Jayate’ takes Twitter by storm – The roads of the capital sported a deserted look around 11 am on Sunday morning, as everyone was hooked on to their TV sets. Did you watch the program? What is your opinion? I’m waiting for next 11 AM of next Sunday. Are you?

  • [GEEK SCHOOL] Network Security 3: Windows Defender and a Malware-Free System

    - by Ciprian Rusen
    In this second lesson we are going to talk about one of the most confusing security products that are bundled with Windows: Windows Defender. In the past, this product has had a bad reputation and for good reason – it was very limited in its capacity to protect your computer from real-world malware. However, the latest version included in Windows 8.x operating systems is much different than in the past and it provides real protection to its users. The nice thing about Windows Defender in its current incarnation, is that it protects your system from the start, so there are never gaps in coverage. We will start this lesson by explaining what Windows Defender is in Windows 7 and Vista versus what it is in Windows 8, and what product to use if you are using an earlier version. We next will explore how to use Windows Defender, how to improve its default settings, and how to deal with the alerts that it displays. As you will see, Windows Defender will have you using its list of quarantined items a lot more often than other security products. This is why we will explain in detail how to work with it and remove malware for good or restore those items that are only false alarms. Lastly, you will learn how to turn off Windows Defender if you no longer want to use it and you prefer a third-party security product in its place and then how to enable it back, if you have changed your mind about using it. Upon completion, you should have a thorough understanding of your system’s default anti-malware options, or how to protect your system expeditiously. What is Windows Defender? Unfortunately there is no one clear answer to this question because of the confusing way Microsoft has chosen to name its security products. Windows Defender is a different product, depending on the Windows operating system you are using. If you use Windows Vista or Windows 7, then Windows Defender is a security tool that protects your computer from spyware. This but one form of malware made out of tools and applications that monitor your movements on the Internet or the activities you make on your computer. Spyware tends to send the information that is collected to a remote server and it is later used in all kinds of malicious purposes, from displaying advertising you don’t want, to using your personal data, etc. However, there are many other types of malware on the Internet and this version of Windows Defender is not able to protect users from any of them. That’s why, if you are using Windows 7 or earlier, we strongly recommend that you disable Windows Defender and install a more complete security product like Microsoft Security Essentials, or third-party security products from specialized security vendors. If you use Windows 8.x operating systems, then Windows Defender is the same thing as Microsoft Security Essentials: a decent security product that protects your computer in-real time from viruses and spyware. The fact that this product protects your computer also from viruses, not just from spyware, makes a huge difference. If you don’t want to pay for security products, Windows Defender in Windows 8.x and Microsoft Security Essentials (in Windows 7 or earlier) are good alternatives. Windows Defender in Windows 8.x and Microsoft Security Essentials are the same product, only their name is different. In this lesson, we will use the Windows Defender version from Windows 8.x but our instructions apply also to Microsoft Security Essentials (MSE) in Windows 7 and Windows Vista. If you want to download Microsoft Security Essentials and try it out, we recommend you to use this page: Download Microsoft Security Essentials. There you will find both 32-bit and 64-bit editions of this product as well versions in multiple languages. How to Use and Configure Windows Defender Using Windows Defender (MSE) is very easy to use. To start, search for “defender” on the Windows 8.x Start screen and click or tap the “Windows Defender” search result. In Windows 7, search for “security” in the Start Menu search box and click “Microsoft Security Essentials”. Windows Defender has four tabs which give you access to the following tools and options: Home – here you can view the security status of your system. If everything is alright, then it will be colored in green. If there are some warnings to consider, then it will be colored in yellow, and if there are threats that must be dealt with, everything will be colored in red. On the right side of the “Home” tab you will find options for scanning your computer for viruses and spyware. On the bottom of the tab you will find information about when the last scan was performed and what type of scan it was. Update – here you will find information on whether this product is up-to-date. You will learn when it was last updated and the versions of the definitions it is using. You can also trigger a manual update. History – here you can access quarantined items, see which items you’ve allowed to run on your PC even if they were identified as malware by Windows Defender, and view a complete list with all the malicious items Windows Defender has detected on your PC. In order to access all these lists and work with them, you need to be signed in as an administrator. Settings – this is the tab where you can turn on the real-time protection service, exclude files, file types, processes, and locations from its scans as well as access a couple of more advanced settings. The only difference between Windows Defender in Windows 8.x and Microsoft Security Essentials (in Windows 7 or earlier) is that, in the “Settings” tab, Microsoft Security Essentials allows you to set when to run scheduled scans while Windows Defender lacks this option.

  • Amanda Todd&ndash;What Parents Can Learn From Her Story

    - by D'Arcy Lussier
    Amanda Todd was a bullied teenager who committed suicide this week. Her story has become headline news due in part to her You Tube video she posted telling her story:   The story is heartbreaking for so many reasons, but I wanted to talk about what we as parents can learn from this. Being the dad to two girls, one that’s 10, I’m very aware of the dangers that the internet holds. When I saw her story, one thing jumped out at me – unmonitored internet access at an early age. My daughter (then 9) came home from a friends place once and asked if she could be in a YouTube video with her friend. Apparently this friend was allowed to do whatever she wanted on the internet, including posting goofy videos. This set off warning bells and we ensured our daughter realized the dangers and that she was not to ever post videos of herself. In looking at Amanda’s story, the access to unmonitored internet time along with just being a young girl and being flattered by an online predator were the key events that ultimately led to her suicide. Yes, the reaction of her classmates and “friends” was horrible as well, I’m not diluting that. But our youth don’t fully understand yet that what they do on the internet today will follow them potentially forever. And the people they meet online aren’t necessarily who they claim to be. So what can we as parents learn from Amanda’s story? Parents Shouldn’t Feel Bad About Being Internet Police Our job as parents is in part to protect our kids and keep them safe, even if they don’t like our measures. This includes monitoring, supervising, and restricting their internet activities. In our house we have a family computer in the living room that the kids can watch videos and surf the web. It’s in plain view of everyone, so you can’t hide what you’re looking at. If our daughter goes to a friend’s place, we ask about what they did and what they played. If the computer comes up, we ask about what they did on it. Luckily our daughter is very up front and honest in telling us things, so we have very open discussions. Parents Need to Be Honest About the Dangers of the Internet I’m sure every generation says that “kids grow up so fast these days”, but in our case the internet really does push our kids to be exposed to things they otherwise wouldn’t experience. One wrong word in a Google search, a click of a link in a spam email, or just general curiosity can expose a child to things they aren’t ready for or should never be exposed to (and I’m not just talking about adult material – have you seen some of the graphic pictures from war zones posted on news sites recently?). Our stance as parents has been to be open about discussing the dangers with our kids before they encounter any content – be proactive instead of reactionary. Part of this is alerting them to the monsters that lurk on the internet as well. As kids explore the world wide web, they’re eventually going to encounter some chat room or some Facebook friend invite or other personal connection with someone. More than ever kids need to be educated on the dangers of engaging with people online and sharing personal information. You can think of it as an evolved discussion that our parents had with us about using the phone: “Don’t say ‘I’m home alone’, don’t say when mom or dad get home, don’t tell them any information, etc.” Parents Need to Talk Self Worth at Home Katie makes the point better than I ever could (one bad word towards the end): Our children need to understand their value beyond what the latest issue of TigerBeat says, or the media who continues flaunting physical attributes over intelligence and character, or a society that puts focus on status and wealth. They also have to realize that just because someone pays you a compliment, that doesn’t mean you should ignore personal boundaries and limits. What does this have to do with the internet? Well, in days past if you wanted to be social you had to go out somewhere. Now you can video chat with any number of people from the comfort of wherever your laptop happens to be – and not just text but full HD video with sound! While innocent children head online in the hopes of meeting cool people, predators with bad intentions are heading online too. As much as we try to monitor their online activity and be honest about the dangers of the internet, the human side of our kids isn’t something we can control. But we can try to influence them to see themselves as not needing to search out the acceptance of complete strangers online. Way easier said than done, but ensuring self-worth is something discussed, encouraged, and celebrated is a step in the right direction. Parental Wake Up Call This post is not a critique of Amanda’s parents. The reality is that cyber bullying/abuse is happening every day, and there are millions of parents that have no clue its happening to their children. Amanda’s story is a wake up call that our children’s online activities may be putting them in danger. My heart goes out to the parents of this girl. As a father of daughters, I can’t imagine what I would do if I found my daughter having to hide in a ditch to avoid a mob or call 911 to report my daughter had attempted suicide by drinking bleach or deal with a child turning to drugs/alcohol/cutting to cope. It would be horrendous if we as parents didn’t re-evaluate our family internet policies in light of this event.

  • How to Customize Fonts and Colors for Gnome Panels in Ubuntu Linux

    - by The Geek
    Earlier this week we showed you how to make the Gnome Panels totally transparent, but you really need some customized fonts and colors to make the effect work better. Here’s how to do it. This article is the first part of a multi-part series on how to customize the Ubuntu desktop, written by How-To Geek reader and ubergeek, Omar Hafiz. Changing the Gnome Colors the Easy Way You’ll first need to install Gnome Color Chooser which is available in the default repositories (the package name is gnome-color-chooser). Then go to System > Preferences > Gnome Color Chooser to launch the program. When you see all these tabs you immediately know that Gnome Color Chooser does not only change the font color of the panel, but also the color of the fonts all over Ubuntu, desktop icons, and many other things as well. Now switch to the panel tab, here you can control every thing about your panels. You can change font, font color, background and background color of the panels and start menus. Tick the “Normal” option and choose the color you want for the panel font. If you want you can change the hover color of the buttons on the panel by too. A little below the color option is the font options, this includes the font, font size, and the X and Y positioning of the font. The first two options are pretty straight forward, they change the typeface and the size. The X-Padding and Y-Padding may confuse you but they are interesting, they may give a nice look for your panels by increasing the space between items on your panel like this: X-Padding:   Y-Padding:   The bottom half of the window controls the look of your start menus which is the Applications, Places, and Systems menus. You can customize them just the way you did with the panel.   Alright, this was the easy way to change the font of your panels. Changing the Gnome Theme Colors the Command-Line Way The other hard (not so hard really) way will be changing the configuration files that tell your panel how it should look like. In your Home Folder, press Ctrl+H to show the hidden files, now find the file “.gtkrc-2.0”, open it and insert this line in it. If there are any other lines in the file leave them intact. include “/home/<username>/.gnome2/panel-fontrc” Don’t forget to replace the <user_name> with you user account name. When done close and save the file. Now navigate the folder “.gnome2” from your Home Folder and create a new file and name it “panel-fontrc”. Open the file you just created with a text editor and paste the following in it: style “my_color”{fg[NORMAL] = “#FF0000”}widget “*PanelWidget*” style “my_color”widget “*PanelApplet*” style “my_color” This text will make the font red. If you want other colors you’ll need to replace the Hex value/HTML Notation (in this case #FF0000) with the value of the color you want. To get the hex value you can use GIMP, Gcolor2 witch is available in the default repositories or you can right-click on your panel > Properties > Background tab then click to choose the color you want and copy the Hex value. Don’t change any other thing in the text. When done, save and close. Now press Alt+F2 and enter “killall gnome-panel” to force it to restart or you can log out and login again. Most of you will prefer the first way of changing the font and color for it’s ease of applying and because it gives you much more options but, some may not have the ability/will to download and install a new program on their machine or have reasons of their own for not to using it, that’s why we provided the two way.

  • Discover What Powers Your Favorite Websites

    - by Matthew Guay
    Have you ever wondered if the site you’re visiting is powered by WordPress or if the webapp you’re using is powered by Ruby on Rails?  With these extensions for Google Chrome, you’ll never have to wonder again. Geeks love digging under the hood to see what makes their favorite apps and sites tick.  But opening the “View Source” window today doesn’t tell you everything there is to know about a website.  Plus, even if you can tell what CMS is powering a website from its source, it can be tedious to dig through lines of code to find what you’re looking for.  Also, the HTML code never tells you what web server a site is running on or what version of PHP it’s using.  With three extensions for Google Chrome you’ll never have to wonder again.  Note that some sites may not give as much information, but still, you’ll find enough data from most sites to be interesting. Discover Web Frameworks and Javascript Libraries with Chrome Sniffer If you want to know what CMS is powering a site or if it’s using Google Analytics or Quantcast, this is the extension for you.  Chrome Sniffer (link below) identifies over 40 different frameworks, and is constantly adding more.  It shows the logo of the main framework on the site on the left of your address bar.  Here wee see Chrome Sniffer noticed that How-To Geek is powered by WordPress.   Click the logo to see other frameworks on the site.  We can see that the site also has Google Analytics and Quantcast.  If you want more information about the framework, click on its logo and the framework’s homepage will open in a new tab. As another example, we can see that the Tumblr Staff blog is powered by Tumblr (of course), the Discus comment system, Quantcast, and the Prototype JavaScript framework. Or here’s a site that’s powered by Drupal, Google Analytics, Mollom spam protection, and jQuery.  Chrome Sniffer definitely uncovers a lot of neat stuff, so if you’re into web frameworks you’re sure to enjoy this extension. Find Out What Web Server The Site is Running On Want to know whether the site you’re looking at is running on IIS or Appache?  The Web Server Notifier extension for Chrome (link below) lets you easily recognize the web server a site is running on by its favicon on the right of the address bar.  Click the icon to see more information. Some web servers will show you a lot of information about their server, including version, operating system, PHP version, OpenSSL version, and more. Others will simply tell you their name. If the site is powered by IIS, you can usually tell the version of Windows Server its running on since the IIS versions are specific to a version of Windows.  Here we see that Microsoft.com is running on the latest and greatest – Windows Server 2008 R2 with IIS 7.5. Discover Web Technologies Powering Sites Wondering if a webapp is powered by Ruby on Rails or ASP.NET?  The Web Technology Notifier extension for Chrome (link below), from the same developer as the Web Server Notifier, will let you easily discover the backend of a site.  You’ll see the technology’s favicon on the right of your address bar, and, as with the other extension, can get more information by clicking the icon. Here we can see that Backpack from 37signals is powered by the Phusion Passenger module to run Ruby on Rails.   Microsoft’s new Docs.com Office Online apps is powered by ASP.NET…   And How-To Geek has PHP running to power WordPress. Conclusion With all these tools at hand, you can find out a lot about your favorite sites.  For example, with all three extensions we can see that How-To Geek runs on WordPress with PHP, uses Google Analytics and Quantcast, and is served by the LightSpeed web server.  Fun info, huh?   Links Download the Chrome Sniffer extension Download the Web Server Notifier extension Download the Web Technology Notifier extension Similar Articles Productive Geek Tips Enjoy a Clean Start Page with New Tab PageEnjoy Image Zooming on Your Favorite Photo Websites in ChromeAdd Your Own Folders to Favorites in Windows 7Find User Scripts for Your Favorite Websites the Easy WayAdd Social Elements to Your Gmail Contacts with Rapportive TouchFreeze Alternative in AutoHotkey The Icy Undertow Desktop Windows Home Server – Backup to LAN The Clear & Clean Desktop Use This Bookmarklet to Easily Get Albums Use AutoHotkey to Assign a Hotkey to a Specific Window Latest Software Reviews Tinyhacker Random Tips Xobni Plus for Outlook All My Movies 5.9 CloudBerry Online Backup 1.5 for Windows Home Server Snagit 10 tinysong gives a shortened URL for you to post on Twitter (or anywhere) 10 Superb Firefox Wallpapers OpenDNS Guide Google TV The iPod Revolution Ultimate Boot CD can help when disaster strikes

  • My Red Gate Experience

    - by Colin Rothwell
    I’m Colin, and I’ve been an intern working with Mike in publishing on Simple-Talk and SQLServerCentral for the past ten weeks. I’ve mostly been working “behind the scenes”, making improvements to the spam filtering, along with various other small tweaks. When I arrived at Red Gate, one of the first things Mike asked me was what I wanted to get out of the internship. It wasn’t a question I’d given a great deal of thought to, but my immediate response was the same as almost anybody: to support my growing family. Well, ok, not quite that, but money was certainly a motivator, along with simply making sure that I didn’t get bored over the summer. Three months is a long time to fill, and many of my friends end up getting bored, or worse, knitting obsessively. With the arrogance which seems fairly common among Cambridge people, I wasn’t expecting to really learn much here! In my mind, the part of the year where I am at Uni is the part where I learn things, whilst Red Gate would be an opportunity to apply what I’d learnt. Thankfully, the opposite is true: I’ve learnt a lot during my time here, and there has been a definite positive impact on the way I write code. The first thing I’ve really learnt is that test-driven development is, in general, a sensible way of working. Before coming, I didn’t really get it: how could you test something you hadn’t yet written? It didn’t make sense! My problem was seeing a test as having to test all the behaviour of a given function. Writing tests which test the bare minimum possible and building them up is a really good way of crystallising the direction the code needs to grow in, and ensures you never attempt to write too much code at time. One really good experience of this was early on in my internship when Mike and I were working on the query used to list active authors: I’d written something which I thought would do the trick, but by starting again using TDD we grew something which revealed that there were several subtle mistakes in the query I’d written. I’ve also been awakened to the value of pair programming. Whilst I could sort of see the point before coming, I also thought that it was impossible that two people would ever get more done at the same computer than if they were working separately. I still think that this is true for projects with pieces that developers can easily work on independently, and with developers who both know the codebase, but I’ve found that pair programming can be really good for learning a code base, and for building up small projects to the point where you can start working on separate components, as well as solving particularly difficult problems. Later on in my internship, for my down tools week project, I was working on adding Python support to Glimpse. Another intern and I we pair programmed the entire project, using ping pong pair programming as much as possible. One bonus that this brought which I wasn’t expecting was that I found myself less prone to distraction: with someone else peering over my shoulder, I didn’t have the ever-present temptation to open gmail, or facebook, or yammer, or twitter, or hacker news, or reddit, and so on, and so forth. I’m quite proud of this project: I think it’s some of the best code I’ve written. I’ve also been really won over to the value of descriptive variables names. In my pre-Red Gate life, as a lone-ranger style cowboy programmer, I’d developed a tendency towards laziness in variable names, sometimes abbreviating or, worse, using acronyms. I’ve swiftly realised that this is a bad idea when working with a team: saving a few key strokes is inevitably not worth it when it comes to reading code again in the future. Longer names also mean you can do away with a majority of comments. I appreciate that if you’ve come up with an O(n*log n) algorithm for something which seemed O(n^2), you probably want to explain how it works, but explaining what a variable name means is a big no no: it’s so very easy to change the behaviour of the code, whilst forgetting about the comments. Whilst at Red Gate, I took the opportunity to attend a code retreat, which really helped me to solidify all the things I’d learnt. To be completely free of any existing code base really lets you focus on best practises and think about how you write code. If you get a chance to go on a similar event, I’d highly recommend it! Cycling to Red Gate, I’ve also become much better at fitting inner tubes: if you’re struggling to get the tube out, or re-fit the tire, letting a bit of air out usually helps. I’ve also become quite a bit better at foosball and will miss having a foosball table! I’d like to finish off by saying thank you to everyone at Red Gate for having me. I’ve really enjoyed working with, and learning from, the team that brings you this web site. If you meet any of them, buy them a drink!

  • Myths about Coding Craftsmanship part 2

    - by tom
    Myth 3: The source of all bad code is inept developers and stupid people When you review code is this what you assume?  Shame on you.  You are probably making assumptions in your code if you are assuming so much already.  Bad code can be the result of any number of causes including but not limited to using dated techniques (like boxing when generics are available), not following standards (“look how he does the spacing between arguments!” or “did he really just name that variable ‘bln_Hello_Cats’?”), being redundant, using properties, methods, or objects in a novel way (like switching on button.Text between “Hello World” and “Hello World “ //clever use of space character… sigh), not following the SOLID principals, hacking around assumptions made in earlier iterations / hacking in features that should be worked into the overall design.  The first two issues, while annoying are pretty easy to spot and can be fixed so easily.  If your coding team is made up of experienced professionals who are passionate about staying current then these shouldn’t be happening.  If you work with a variety of skills, backgrounds, and experience then there will be some of this stuff going on.  If you have an opportunity to mentor such a developer who is receptive to constructive criticism don’t be a jerk; help them and the codebase will improve.  A little patience can improve the codebase, your work environment, and even your perspective. The novelty and redundancy I have encountered has often been the use of creativity when language knowledge was perceived as unavailable or too time consuming.  When developers learn on the job you get a lot of this.  Rather than going to MSDN developers will use what they know.  Depending on the constraints of their assignment hacking together what they know may seem quite practical.  This was not stupid though I often wonder how much time is actually “saved” by hacking.  These issues are often harder to untangle if we ever do.  They can also grow out of control as we write hack after hack to make it work and get back to some development that is satisfying. Hacking upon an existing hack is what I call “feeding the monster”.  Code monsters are anti-patterns and hacks gone wild.  The reason code monsters continue to get bigger is that they keep growing in scope, touching more and more of the application.  This is not the result of dumb developers. It is probably the result of avoiding design, not taking the time to understand the problems or anticipate or communicate the vision of the product.  If our developers don’t understand the purpose of a feature or product how do we expect potential customers to do so? Forethought and organization are often what is missing from bad code.  Developers who do not use the SOLID principals should be encouraged to learn these principals and be given guidance on how to apply them.  The time “saved” by giving hackers room to hack will be made up for and then some. Not as technical debt but as shoddy work that if not replaced will be struggled with again and again.  Bad code is not the result of dumb developers (usually) it is the result of trying to do too much without the proper resources and neglecting the right thing that needs doing with the first thoughtless thing that comes into our heads. Object oriented code is all about relationships between objects.  Coders who believe their coworkers are all fools tend to write objects that are difficult to work with, not eager to explain themselves, and perform erratically and irrationally.  If you constantly find you are surrounded by idiots you may want to ask yourself if you are being unreasonable, if you are being closed minded, of if you have chosen the right profession.  Opening your mind up to the idea that you probably work with rational, well-intentioned people will probably make you a better coder and it might even make you less grumpy.  If you are surrounded by jerks who do not engage in the exchange of ideas who do not care about their customers or the durability of the code you are building together then I suggest you find a new place to work.  Myth 4: Customers don’t care about “beautiful” code Craftsmanship is customer focused because it means that the job was done right, the product will withstand the abuse, modifications, and scrutiny of our customers.  Users can appreciate a predictable timeline for a release, a product delivered on time and on budget, a feature set that does not interfere with the task(s) it is supporting, quick turnarounds on exception messages, self healing issues, and less issues.  These are all hindered by skimping on craftsmanship.  When we write data access and when we write reusable code.   What do you think?  Does bad code come primarily from low IQ individuals?  Do customers care about beautiful code?

  • Very slow compile times on Visual Studio

    - by johnc
    We are getting very slow compile times, which can take upwards of 20+ minutes on dual core 2GHz, 2G Ram machines. A lot of this is due to the size of our solution which has grown to 70+ projects, as well as VSS which is a bottle neck in itself when you have a lot of files. (swapping out VSS is not an option unfortunately, so I don't want this to descend into a VSS bash) We are looking at combing projects (not nice, as we like the separation of concerns, but is a good opportunity to refactor away some dead wood). We are also looking at having multiple solutions to achieve greater separation of concerns and quicker compile times for each element of the application. This I can see will become a dll hell as we try to keep things in synch. I am interested to know how other teams have dealt with this scaling issue, what do you do when your code base reaches a critical mass that you are wasting half the day watching the status bar deliver compile messages UPDATE Apologies, I neglected to mention this is a C# solution. Thanks for all the cpp suggestions, but it's been a few years since I've had to worry about headers. At a distance I say I miss C++, but I'm not sure I want to go back EDIT: Nice suggestions that have helped so far (not saying there aren't other nice suggestions below, just what has helped) New 3GHz laptop - the power of lost utilization works wonders when whinging to management Disable Anti Virus during compile 'Disconnecting' from VSS (actually the network) during compile - I may get us to remove VS-VSS integration altogether and stick to using the VSS UI Still not rip-snorting through a compile, but every bit helps. Orion did mention in a comment that generics may have a play also. From my tests there does appear to be a minimal performance hit, but not high enough to sure - compile times can be inconsistent due to disc activity. Due to time limitations, my tests didn't include as many Generics, or as much code, as would appear in live system, so that may accumulate. I wouldn't avoid using generics where they are supposed to be used, just for compile time performance WORKAROUND We are testing the practice of building new areas of the application in new solutions, importing in the latest dlls as required, them integrating them into the larger solution when we are happy with them. We may also do them same to existing code by creating temporary solutions that just encapsulate the areas we need to work on, and throwing them away after reintegrating the code. We need to weigh up the time it will take to reintegrate this code against the time we gain by not having Rip Van Winkle like experiences with rapid recompiling during development.

  • Issues with MIPS interrupt for tv remote simulator

    - by pred2040
    Hello I am writing a program for class to simulate a tv remote in a MIPS/SPIM enviroment. The functions of the program itself are unimportant as they worked fine before the interrupt so I left them all out. The gaol is basically to get a input from the keyboard by means of interupt, store it in $s7 and process it. The interrupt is causing my program to repeatedly spam the errors: Exception occurred at PC=0x00400068 Bad address in data/stack read: 0x00000004 Exception occurred at PC=0x00400358 Bad address in data/stack read: 0x00000000 program starts here .data msg_tvworking: .asciiz "tv is working\n" msg_sec: .asciiz "sec -- " msg_on: .asciiz "Power On" msg_off: .asciiz "Power Off" msg_channel: .asciiz " Channel " msg_volume: .asciiz " Volume " msg_sleep: .asciiz " Sleep Timer: " msg_dash: .asciiz "-\n" msg_newline: .asciiz "\n" msg_comma: .asciiz ", " array1: .space 400 # 400 bytes of storage for 100 channels array2: .space 400 # copy of above for sorting var1: .word 0 # 1 if 0-9 is pressed, 0 if not var2: .word 0 # stores number of channel (ex. 2-) var3: .word 0 # channel timer var4: .word 0 # 1 if s pressed once, 2 if twice, 0 if not var5: .word 0 # sleep wait timer var6: .word 0 # program timer var9: .float 0.01 # for channel timings .kdata var7: .word 10 var8: .word 11 .text .globl main main: li $s0, 300 li $s1, 0 # channel li $s2, 50 # volume li $s3, 1 # power - 1:on 0:off li $s4, 0 # sleep timer - 0:off li $s5, 0 # temporary li $s6, 0 # length of sleep period li $s7, 10000 # current key press li $t2, 0 # temp value not needed across calls li $t4, 0 interrupt data here mfc0 $a0, $12 ori $a0, 0xff11 mtc0 $a0, $12 lui $t0, 0xFFFF ori $a0, $0, 2 sw $a0, 0($t0) mainloop: # 1. get external input, and process it # input from interupt is taken from $a2 and placed in $s7 #for processing beq $a2, $0, next lw $s7, 4($a2) li $a2, 0 # call the process_input function here # jal process_input next: # 2. check sleep timer mainloopnext1: # 3. delay for 10ms jal delay_10ms jal check_timers jal channel_time # 4. print status lw $s5, var6 addi $s5, $s5, 1 sw $s5, var6 addi $s0, $s0, -1 bne $s0, $0, mainloopnext4 li $s0, 300 jal status_print mainloopnext4: j mainloop li $v0,10 # exit syscall -------------------------------------------------- status_print: seconds_stat: power_stat: on_stat: off_stat: channel_stat: volume_stat: sleep_stat: j $ra -------------------------------------------------- delay_10ms: li $t0, 6000 delay_10ms_loop: addi $t0, $t0, -1 bne $t0, $0, delay_10ms_loop jr $ra -------------------------------------------------- check_timers: channel_press: sleep_press: go_back_press: channel_check: channel_ignore: sleep_check: sleep_ignore: j $ra ------------------------------------------------ process_input: beq $s7, 112, power beq $s7, 117, channel_up beq $s7, 100, channel_down beq $s7, 108, volume_up beq $s7, 107, volume_down beq $s7, 115, sleep_init beq $s7, 118, history bgt $s7, 47, end_range jr $ra end_range: power: on: off: channel_up: over: channel_down: under: channel_message: channel_time: volume_up: volume_down: volume_message: sleep_init: sleep_incr: sleep: sleep_reset: history: digit_pad_init: digit_pad: jr $ra -------------------------------------------- interupt data here, followed closely from class .ktext 0x80000180 .set noat move $k1, $at .set at sw $v0, var7 sw $a0, var8 mfc0 $k0, $13 srl $a0, $k0, 2 andi $a0, $a0, 0x1f bne $a0, $zero, no_io lui $v0, 0xFFFF lw $a2, 4($v0) # keyboard data placed in $a2 no_io: mtc0 $0, $13 mfc0 $k0, $12 andi $k0, 0xfffd ori $k0, 0x11 mtc0 $k0, $12 lw $v0, var7 lw $a0, var8 .set noat move $at, $k1 .set at eret Thanks in advance.

  • Unable to rename file with c# ftp methods when current user directory is different from root

    - by Agata
    Hello everyone, Remark: due to spam prevention mechanizm I was forced to replace the beginning of the Uris from ftp:// to ftp. I've got following problem. I have to upload file with C# ftp method and afterwards rename it. Easy, right? :) Ok, let's say my ftp host is like this: ftp.contoso.com and after logging in, current directory is set to: users/name So, what I'm trying to achieve is to log in, upload file to current directory as file.ext.tmp and after upload is successful, rename the file to file.ext The whole difficulty is, as I guess, to properly set the request Uri for FtpWebRequest. MSDN states: The URI may be relative or absolute. If the URI is of the form "ftp://contoso.com/%2fpath" (%2f is an escaped '/'), then the URI is absolute, and the current directory is /path. If, however, the URI is of the form "ftp://contoso.com/path", first the .NET Framework logs into the FTP server (using the user name and password set by the Credentials property), then the current directory is set to UserLoginDirectory/path. Ok, so I upload file with the following URI: ftp.contoso.com/file.ext.tmp Great, the file lands where I wanted it to be: in directory "users/name" Now, I want to rename the file, so I create web request with following Uri: ftp.contoso.com/file.ext.tmp and specify rename to parameter as: file.ext and this gives me 550 error: file not found, no permissions, etc. I traced this in Microsoft Network Monitor and it gave me: Command: RNFR, Rename from CommandParameter: /file.ext.tmp Ftp: Response to Port 53724, '550 File /file.ext.tmp not found' as if it was looking for the file in the root directory - not in the current directory. I renamed the file manually using Total Commander and the only difference was that CommandParameter was without the first slash: CommandParameter: file.ext.tmp I'm able to successfully rename the file by supplying following absolute URI: ftp.contoso.com/%2fusers/%2fname/file.ext.tmp but I don't like this approach, since I would have to know the name of current user's directory. It can probably be done by using WebRequestMethods.Ftp.PrintWorkingDirectory, but it adds extra complexity (calling this method to retrieve directory name, then combining the paths to form proper URI). What I don't understand is why the URI ftp.contoso.com/file.ext.tmp is good for upload and not for rename? Am I missing something here? The project is set to .NET 4.0, coded in Visual Studio 2010.

  • WCF Duplex net.tcp issues on win7

    - by Tom
    We have a WCF service with multiple clients to schedule operations amongst clients. It worked great on XP. Moving to win7, I can only connect a client to the server on the same machine. At this point, I'm thinking it's something to do with IPv6, but I'm stumped as to how to proceed. Client trying to connect to a remote server gives the following exception: System.ServiceModel.EndpointNotFoundException: Could not connect to net.tcp://10.7.11.14:18297/zetec/Service/SchedulerService/Scheduler. The connection attempt lasted for a time span of 00:00:21.0042014. TCP error code 10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 10.7.11.14:18297. --- System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 10.7.11.14:18297 The service is configured like so: <system.serviceModel> <services> <service name="SchedulerService" behaviorConfiguration="SchedulerServiceBehavior"> <host> <baseAddresses> <add baseAddress="net.tcp://localhost/zetec/Service/SchedulerService"/> </baseAddresses> </host> <endpoint address="net.tcp://localhost:18297/zetec/Service/SchedulerService/Scheduler" binding="netTcpBinding" bindingConfiguration = "ConfigBindingNetTcp" contract="IScheduler" /> <endpoint address="net.tcp://localhost:18297/zetec/Service/SchedulerService/Scheduler" binding="netTcpBinding" bindingConfiguration = "ConfigBindingNetTcp" contract="IProcessingNodeControl" /> </service> </services> <bindings> <netTcpBinding> <binding name = "ConfigBindingNetTcp" portSharingEnabled="True"> <security mode="None"/> </binding> </netTcpBinding > </bindings> <behaviors> <serviceBehaviors> <behavior name="SchedulerServiceBehavior"> <serviceDebug includeExceptionDetailInFaults="true" /> <serviceThrottling maxConcurrentSessions="100"/> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel> I've checked my firewall about a dozen times, but I guess there could be something I'm missing. Tried disabling windows firewall. I tried changing localhost to my ipv4 address to try to keep away from ipv6, I've tried removing any anti-ipv6 code.

I am facing an annoying bug, each time I send a malformed SOAP object to my web service, sun's api spam the System.out with logs like this: javax.xml.ws.WebServiceException: com.sun.istack.XMLStreamException2: org.xml.sax.SAXParseException: cvc-complex-type.4: Attribute 'type' must appear on element 'object'. at com.sun.xml.ws.util.pipe.AbstractSchemaValidationTube.doProcess(AbstractSchemaValidationTube.java:206) at com.sun.xml.ws.util.pipe.AbstractSchemaValidationTube.processRequest(AbstractSchemaValidationTube.java:175) at com.sun.xml.ws.api.pipe.Fiber.__doRun(Fiber.java:595) at com.sun.xml.ws.api.pipe.Fiber._doRun(Fiber.java:554) at com.sun.xml.ws.api.pipe.Fiber.doRun(Fiber.java:539) at com.sun.xml.ws.api.pipe.Fiber.runSync(Fiber.java:436) at com.sun.xml.ws.server.WSEndpointImpl$2.process(WSEndpointImpl.java:243) at com.sun.xml.ws.transport.http.HttpAdapter$HttpToolkit.handle(HttpAdapter.java:444) at com.sun.xml.ws.transport.http.HttpAdapter.handle(HttpAdapter.java:244) at com.sun.xml.ws.transport.http.server.WSHttpHandler.handleExchange(WSHttpHandler.java:106) at com.sun.xml.ws.transport.http.server.WSHttpHandler.handle(WSHttpHandler.java:91) at com.sun.net.httpserver.Filter$Chain.doFilter(Filter.java:65) at sun.net.httpserver.AuthFilter.doFilter(AuthFilter.java:54) at com.sun.net.httpserver.Filter$Chain.doFilter(Filter.java:68) at sun.net.httpserver.ServerImpl$Exchange$LinkHandler.handle(ServerImpl.java:555) at com.sun.net.httpserver.Filter$Chain.doFilter(Filter.java:65) at sun.net.httpserver.ServerImpl$Exchange.run(ServerImpl.java:527) at sun.net.httpserver.ServerImpl$DefaultExecutor.execute(ServerImpl.java:119) at sun.net.httpserver.ServerImpl$Dispatcher.handle(ServerImpl.java:349) at sun.net.httpserver.ServerImpl$Dispatcher.run(ServerImpl.java:321) at java.lang.Thread.run(Thread.java:619) Caused by: com.sun.istack.XMLStreamException2: org.xml.sax.SAXParseException: cvc-complex-type.4: Attribute 'type' must appear on element 'object'. at com.sun.xml.ws.util.xml.StAXSource$1.parse(StAXSource.java:185) at com.sun.xml.ws.util.xml.StAXSource$1.parse(StAXSource.java:170) at org.apache.xerces.jaxp.validation.ValidatorHandlerImpl.validate(Unknown Source) at org.apache.xerces.jaxp.validation.ValidatorImpl.validate(Unknown Source) at javax.xml.validation.Validator.validate(Validator.java:127) at com.sun.xml.ws.util.pipe.AbstractSchemaValidationTube.doProcess(AbstractSchemaValidationTube.java:204) ... 20 more I would like to switch off this log or redirect it to my error/warn/debug.log files used by log4j. I tried to add a rule in my log4j.xml file : <category name="javax.xml.ws"> <priority value="error" /> </category> It didn't worked. So I tried the following trick: java.util.logging.Logger.getLogger("javax.xml.ws.WebServiceException").setLevel( java.util.logging.Level.OFF); it didn't worked neither. Any ideas ? It is not a big issue but it makes my catalina.log getting bigger & bigger and it's not the appropriate place for this kind of log. Chris

  • Good Email Notification Sending Service

    - by Philibert Perusse
    I need to send a few but important email notifications to individual users. For instance, when they register their software I send them a confirmation email. Right now, I am using 'sendmail' from my Perl CGI script to do the job. Most of my automated email are lost or marked as junk. Unfortunately, I am using shared hosting services and not a very good control over the SPF and SenderID DNS records. Even more bad, some other user of that shared server has been infected with some kind of SPAM-BOT and the IP is now blacklisted until further notice! Anyway I just don't want to deal with this kind of headache. I am looking for an online service that I will be able to subscribe to and pay something like 0.10$ per email I send with no monthly fees. I just need and API to be able to send the email from PHP or Perl code I will have to write. I have been looking around at all those "Email Sending Services" and they are all wrapped around creating campains and managing lists for bulk email marketing distribution and newsletters. But remember, I want to send an email notification to a "single" recipient. So far, I have look at MailChimp, SocketLabs, iContact, ConstantContact, StreamSend and so many others to no avail. I have seen one comment at Hackers News saying that MailChimp have an API for transactional e-mails (i.e. ad-hoc ones to welcome a user for example). So you're not just restricted to using them for bulk emails But I cannot find this in the API documentation supplied, maybe this was removed. Any suggestions out there. Here is a summary of my requirements: Allows ad hoc sending of email to a single recipient. Throughput may well be throttle I don't care, i am sending like 2-5 emails a day. API available in PHP or Perl to connect to that web service. Ideally I can send HTML formatted emails, otherwise I will live with text only. Solution not too expensive, between 0.01$ and 0.25$ per email would be acceptable. No recurring monthly fees.

  • Parallel.For System.OutOfMemoryException

    - by Martin Neal
    We have a fairly simple program that's used for creating backups. I'm attempting to parallelize it but am getting an OutofMemoryException within an AggregateExcption. Some of the source folders are quite large, and the program doesn't crash for about 40 minutes after it starts. I don't know where to start looking so the below code is a near exact dump of all code the code sans directory structure and Exception logging code. Any advise as to where to start looking? using System; using System.Diagnostics; using System.IO; using System.Threading.Tasks; namespace SelfBackup { class Program { static readonly string[] saSrc = { "\\src\\dir1\\", //... "\\src\\dirN\\", //this folder is over 6 GB }; static readonly string[] saDest = { "\\dest\\dir1\\", //... "\\dest\\dirN\\", }; static void Main(string[] args) { Parallel.For(0, saDest.Length, i => { try { if (Directory.Exists(sDest)) { //Delete directory first so old stuff gets cleaned up Directory.Delete(sDest, true); } //recursive function clsCopyDirectory.copyDirectory(saSrc[i], sDest); } catch (Exception e) { //standard error logging CL.EmailError(); } }); } } /////////////////////////////////////// using System.IO; using System.Threading.Tasks; namespace SelfBackup { static class clsCopyDirectory { static public void copyDirectory(string Src, string Dst) { Directory.CreateDirectory(Dst); /* Copy all the files in the folder If and when .NET 4.0 is installed, change Directory.GetFiles to Directory.Enumerate files for slightly better performance.*/ Parallel.ForEach<string>(Directory.GetFiles(Src), file => { /* An exception thrown here may be arbitrarily deep into this recursive function there's also a good chance that if one copy fails here, so too will other files in the same directory, so we don't want to spam out hundreds of error e-mails but we don't want to abort all together. Instead, the best solution is probably to throw back up to the original caller of copy directory an move on to the next Src/Dst pair by not catching any possible exception here.*/ File.Copy(file, //src Path.Combine(Dst, Path.GetFileName(file)), //dest true);//bool overwrite }); //Call this function again for every directory in the folder. Parallel.ForEach(Directory.GetDirectories(Src), dir => { copyDirectory(dir, Path.Combine(Dst, Path.GetFileName(dir))); }); } }

  • How can I handle UTF-8 while posting to a vBulletin board with WWW::Mechanize?

    - by MrMirror
    I have a problem with some automating posting to bulletin board... If I send the posting form to the vBulletin board, I get corrupted entities. Feel free to copy-paste the script and try it... It looks like the board's expecting some decoded utf8, but if I send the message decoded the entities are still wrong. #!/usr/bin/perl use strict; use warnings; use WWW::Mechanize; use Digest::MD5 qw(md5_hex); my $mech = WWW::Mechanize->new(); my $base_url = 'http://www.boerse.bz/'; my $username = 'MrMirror'; my $password = 'test'; $mech->get($base_url); print "Login\n"; $mech->form_number(1); $mech->field('vb_login_username' => $username); $mech->field('vb_login_password' => $password); $mech->field('vb_login_md5password' => md5_hex($password)); $mech->field('vb_login_md5password_utf' => md5_hex($password)); $mech->submit(); unless ($mech->content() =~ m!Weiterleitung!gi) { print "No Rediction!\n"; exit; } print "Redict\n"; $mech->get($base_url); unless ($mech->content() =~ m!Logout!gi) { print "Login Failed!\n"; exit; } $mech->get($base_url .'/newthread.php?do=newthread&f=173'); $mech->form_number(3); $mech->field('subject' => 'MrMirror makes some testing ä ö ü ß'); $mech->field('message' => "ä ö ü ß"); ### everything allright here $mech->dump_forms(); ### preview submit, don't wanna spam around ;) $mech->click('preview'); print "\n\n\n---------------------------------------------------------------------\n\n\n"; ### same form, wrong entities :( $mech->dump_forms();

  • Singleton: How should it be used

    - by Loki Astari
    Edit: From another question I provided an answer that has links to a lot of questions/answers about singeltons: More info about singletons here: So I have read the thread Singletons: good design or a crutch? And the argument still rages. I see Singletons as a Design Pattern (good and bad). The problem with Singleton is not the Pattern but rather the users (sorry everybody). Everybody and their father thinks they can implement one correctly (and from the many interviews I have done, most people can't). Also because everybody thinks they can implement a correct Singleton they abuse the Pattern and use it in situations that are not appropriate (replacing global variables with Singletons!). So the main questions that need to be answered are: When should you use a Singleton How do you implement a Singleton correctly My hope for this article is that we can collect together in a single place (rather than having to google and search multiple sites) an authoritative source of when (and then how) to use a Singleton correctly. Also appropriate would be a list of Anti-Usages and common bad implementations explaining why they fail to work and for good implementations their weaknesses. So get the ball rolling: I will hold my hand up and say this is what I use but probably has problems. I like "Scott Myers" handling of the subject in his books "Effective C++" Good Situations to use Singletons (not many): Logging frameworks Thread recycling pools /* * C++ Singleton * Limitation: Single Threaded Design * See: http://www.aristeia.com/Papers/DDJ_Jul_Aug_2004_revised.pdf * For problems associated with locking in multi threaded applications * * Limitation: * If you use this Singleton (A) within a destructor of another Singleton (B) * This Singleton (A) must be fully constructed before the constructor of (B) * is called. */ class MySingleton { private: // Private Constructor MySingleton(); // Stop the compiler generating methods of copy the object MySingleton(MySingleton const& copy); // Not Implemented MySingleton& operator=(MySingleton const& copy); // Not Implemented public: static MySingleton& getInstance() { // The only instance // Guaranteed to be lazy initialized // Guaranteed that it will be destroyed correctly static MySingleton instance; return instance; } }; OK. Lets get some criticism and other implementations together. :-)

  • How do I solve an AntiForgeryToken exception that occurs after an iisreset in my ASP.Net MVC app?

    - by Colin Newell
    I’m having problems with the AntiForgeryToken in ASP.Net MVC. If I do an iisreset on my web server and a user continues with their session they get bounced to a login page. Not terrible but then the AntiForgery token blows up and the only way to get going again is to blow away the cookie on the browser. With the beta version of version 1 it used to go wrong when reading the cookie back in for me so I used to scrub it before asking for a validation token but that was fixed when it was released. For now I think I’ll roll back to my code that fixed the beta problem but I can’t help but think I’m missing something. Is there a simpler solution, heck should I just drop their helper and create a new one from scratch? I get the feeling that a lot of the problem is the fact that it’s tied so deeply into the old ASP.Net pipeline and is trying to kludge it into doing something it wasn’t really designed to do. I had a look in the source code for the ASP.Net MVC 2 RC and it doesn't look like the code has changed much so while I haven't tried it, I don't think there are any answers there. Here is the relevant part of the stack trace of the exception. Edit: I just realised I didn't mention that this is just trying to insert the token on the GET request. This isn't the validation that occurs when you do a POST kicking off. System.Web.Mvc.HttpAntiForgeryException: A required anti-forgery token was not supplied or was invalid. ---> System.Web.HttpException: Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm.

  • Which third party website thumbnailing services do you use?

    - by Ben Delarre
    I've got a requirement for showing thumbnails of arbitrary websites. I need to be able to show small thumbnails (120px by 90px), and larger thumbnails of around 480px wide. I'll need to specify the queue and invalid placeholder images and preferably have a pingback when the queued images are processed so I can respond appropriately. I'd also need a simple API I can use either directly embedded in my HTML, or from a simple web request to queue the images. I've been looking at various services ranging from low-fi services, to large scale ones - here's some examples: www.bitpixels.com Uses Google AppEngine, seems like a prototype or a toy. Free! www.websnapr.com Tried using this, made a free account and requested a thumbnail. Waited a few minutes and refreshed a couple of times, and ended up having the account banned. Free is tricky yes, but if I can't try it out successfully I'm disinclined to pay. www.shrinktheweb.com Free account seems to be very quick. Lots of documentation on the site, and even covers local caching of the images to your own server (documentation mostly in PHP). Quality of thumbnails look good, and there appear to be sufficient options for setting thumbnail placeholder images and parameters for altering how the thumbnailing is done. Also supports large 'screenshots' of URLs - very useful for me. Discovered the PRO pricing is an à la carte menu, allowing me to select just the features I want and keep the monthly cost low. Excellent stuff, have decided to use this service. www.thumbalizr.com Good coverage of thumbnail sizes and control options - even allowing specification for browser width when thumbnailing. No ping-back, but I can live without that. Supports local caching of images with PHP API, would prefer .NET, but can port it if necessary. Looks like a fairly professional service but seems fairly expensive for the number of thumbnails you get to generate. apologies for lack of proper linking - spam protection! I'm not entirely convinced by any of them, and since this will be a long term service I'd like some stability and support. I'm willing to pay for the service, but I'd want something that fulfills most if not all of my requirements for that. I should also mention that we're hosted on Windows under IIS, so local solutions involving Xvfb and the like sadly can't be used for this project. So my question is: what services do you use? How have they panned out, are you happy with them?
