  • Parse XML function names and call within whole assembly

    - by Matt Clarkson
    Hello all, I have written an application that unit tests our hardware via a internet browser. I have command classes in the assembly that are a wrapper around individual web browser actions such as ticking a checkbox, selecting from a dropdown box as such: BasicConfigurationCommands EventConfigurationCommands StabilizationCommands and a set of test classes, that use the command classes to perform scripted tests: ConfigurationTests StabilizationTests These are then invoked via the GUI to run prescripted tests by our QA team. However, as the firmware is changed quite quickly between the releases it would be great if a developer could write an XML file that could invoke either the tests or the commands: <?xml version="1.0" encoding="UTF-8" ?> <testsuite> <StabilizationTests> <StressTest repetition="10" /> </StabilizationTests> <BasicConfigurationCommands> <SelectConfig number="2" /> <ChangeConfigProperties name="Weeeeee" timeOut="15000" delay="1000"/> <ApplyConfig /> </BasicConfigurationCommands> </testsuite> I have been looking at the System.Reflection class and have seen examples using GetMethod and then Invoke. This requires me to create the class object at compile time and I would like to do all of this at runtime. I would need to scan the whole assembly for the class name and then scan for the method within the class. This seems a large solution, so any information pointing me (and future readers of this post) towards an answer would be great! Thanks for reading, Matt

  • .net Class "is not a member of" Class .. even though it is?

    - by Matt Thrower
    Hi, Looking over some older code, I've run into a strange namespace error. Let's say I have two projects, HelperProject and WebProject. The full namespace of each - as given in application properties - is myEmployer.HelperProject and myEmployer.Web.WebProject. The pages in the web project are full of statements that use classes from the helper project. There are no imports/using statements but there is a reference to the helper project added in the bin. A few example lines might be: myEmployer.HelperProject.StringHelper.GetFixedLengthText(Text, "", Me.Width, 11) myEmploter.HelperProject.Utils.StringHelper.EstimatePixelLength(Text, 11) However every line that is written in this manner is throwing the error 'HelperProject' is not a member of 'myEmployer'. If you declare the statements like this: HelperProject.StringHelper.GetFixedLengthText(Text, "", Me.Width, 11) HelperProject.Utils.StringHelper.EstimatePixelLength(Text, 11) Everything seems fine. In the solution object browser and the bin folder, HelperProject appears with its full namespace, myEmployer.HelperProject. I don't want to have to change all the statements, and besides I suspect this is masking a more fundamental problem here. But I have no idea what's going on. Can anyone offer any pointers please? Cheers, Matt

  • WCF service with PHP client - complex type as parameter not working

    - by Matt F
    Hi, I have a WCF service with three methods. Two of the methods return custom types (these work as expected), and the third method takes a custom type as a parameter and returns a boolean. When calling the third method via a PHP soap client it returns an 'Object reference not set to an instance of an object' exception. Example Custom Type: _ Public Class MyClass Private _propertyA As Double <DataMember()> _ Public Property PropertyA() As Double Get Return _propertyA End Get Set(ByVal value As Double) _propertyA = value End Set End Property Private _propertyB As Double <DataMember()> _ Public Property PropertyB() As Double Get Return _propertyB End Get Set(ByVal value As Double) _propertyB = value End Set End Property Private _propertyC As Date <DataMember()> _ Public Property PropertyC() As Date Get Return _propertyC End Get Set(ByVal value As Date) _propertyC = value End Set End Property End Class Method: Public Function Add(ByVal param As MyClass) As Boolean Implements IService1.Add ' ... End Function PHP client call: $client-Add(array('param'=array( 'PropertyA' = 1, 'PropertyB' = 2, 'PropertyC' = "2009-01-01" ))); The WCF service works fine with a .Net client but I'm new to PHP and can't get this to work. Is it possible to create an instance of 'MyClass' in PHP. Any help would be appreciated. Note: I'm using PHP 5 (XAMPP 1.7.0 for Windows). Thanks Matt

  • Handle order dependence in loops

    - by Matt
    Hey all, I'm making a templating system where I instantiate each tag using a foreach loop. The issue is that some of the tags rely on each other so, I'm wondering how to get around that ordering from the looping. Here's an example: Class A { public $width; __construct() { $this->width = $B->width; // Undefined! Or atleast not set yet.. } } Class B { public $width; __construct() { $this->width = "500px"; } __tostring() { return "Hello World!"; } } Template.php $tags = array("A", "B"); foreach ($tags as $tag) { $TagObj[$tag] = new $tag(); } echo $TagObj['A']->width; // Nadamundo! EDIT: Ok just to clarify.. My main problem is that Class A relies on Class B, but class A is instantiated before class B, so therefore width has not yet been defined in class B. I am looking for a good way to make sure all the classes are loaded for everyone allowing the interdependencies to exist. For the future, please don't consider any syntax errors.. I just made up this example on the spot. Also assume that I have access to class B from class A after class B gets instantiated. I know this has applications elsewhere and I'm sure this has been solved before, if someone could enlighten me or point me in the right direction that'd be great! Thanks! Matt Mueler

  • Unable to use stored procs in a generic repository for the entity framework. (ASP.NET MVC 2)

    - by Matt
    Hi, I have a generic repository that uses the entity framework to manipulate the database. The original code is credited to Morshed Anwar's post on CodeProject. I've taken his code and modified is slightly to fit my needs. Unfortunately I'm unable to call an Imported Function because the function is only recognized for my specific instance of the entity framework public class Repository<E, C> : IRepository<E, C>, IDisposable where E : EntityObject where C : ObjectContext { private readonly C _ctx; public ObjectResult<MyObject> CallFunction() { // This does not work because "CallSomeImportedFunction" only works on // My object. I also cannot cast it (TrackItDBEntities)_ctx.CallSomeImportedFunction(); // Not really sure why though... but either way that kind of ruins the genericness off it. return _ctx.CallSomeImportedFunction(); } } Anyone know how I can make this work with the repository I already have? Or does anyone know a generic way of calling stored procedures with entity framework? Thanks, Matt

  • Php index page utitlizing an idea for a superswitch...

    - by Matt
    I dont know if this is a great idea...or a crap one. But I was thinking I may use one page to display all my pages using includes. Here is what my index.php would look like...on the functions include there is a function called "superSwitch" which will determine what requested page will be included....for instance if I do a get ?a=a it will goto the function superSwitch(a) superSwitch will take it and associate it with (login.php) then respond with such... here is the code for the index.php...please let me know if this makes sense and might work, or should I just stick to long blocks of code (which is why I am trying this because I hate long pages full of code...) of course as you can tell it is not actually including anything yet...the print is for debugging purposes. :) Thanks, Matt <?php //includes Functions include_once('inc/func.inc.php'); //set superget variable $superget = @$_GET['a']; //check if superget is set or null if (!$superget) { echo "Nothing Requested :)"; } else { //sanitizes the superget request $supergetr = supergetSanitize($superget) //uses the result "good" or "nogood" to determine what happens if ( $supergetr == "good" ) { //pulls superSwitch value of the request $ssresult = superSwitch($superget); print_r ($ssresult); } //if the sanitize is nogood else { //the superSwitch is instructed to respond with a 404 page $superget = "404" $ssresult = superSwitch($superget); print_r ($ssresult); } } ?>

  • Resolve php "deadlock"

    - by Matt
    Hey all, I'm currently running into a situation that I guess would be called deadlock. I'm implementing a message service that calls various object methods.. it's quite similar to observer pattern.. Here's whats going on: Dispatcher.php Dispatcher.php <? class Dispatcher { ... public function message($name, $method) { // Find the object based on the name $object = $this->findObjectByName($name); // Slight psuedocode.. for ease of example if($this->not_initialized($object)) $object = new $object(); // This is where it locks up. } return $object->$method(); ... } class A { function __construct() { $Dispatcher->message("B", "getName"); } public function getName() { return "Class A"; } } class B { function __construct() { // Assume $Dispatcher is the classes $Dispatcher->message("A", "getName"); } public function getName() { return "Class B"; } } ?> It locks up when neither object is initialized. It just goes back and forth from message each other and no one can be initialized. Any help would be immensely helpful.. Thanks! Matt Mueller

  • Should a connect method return a value?

    - by Matt S
    I was looking at some code I've inherited and I couldn't decided if I like a bit of code. Basically, there is a method that looks like the following: bool Connect(connection parameters){...} It returns true if it connects successfully, false otherwise. I've written code like that in the past, but now, when I see this method I don't like it for a number of reasons. Its easy to write code that just ignores the returned value, or not realize it returns a value. There is no way to return an error message. Checking the return of the method doesn't really look nice: if (!Connect(...)){....} I could rewrite code to throw an exception when it doesn't successfully connect, but I don't consider that an exceptional situation. Instead I'm thinking of refactoring the code as follows: void Connect(Connection Parameters, out bool successful, out string errorMessage){...} I like that other developers have to provide the success and error strings so they know the method has error conditions and I can know return a message Anyone have any thoughts on the matter? Thanks -Matt

  • Resolve php endless recursion issue

    - by Matt
    Hey all, I'm currently running into an endless recursion situation. I'm implementing a message service that calls various object methods.. it's quite similar to observer pattern..

  • Modularizing web applications

    - by Matt
    Hey all, I was wondering how big companies tend to modularize components on their page. Facebook is a good example: There's a team working on Search that has its own CSS, javascript, html, etc.. There's a team working on the news feed that has its own CSS, javascript, html, etc... ... And the list goes on They cannot all be aware of what everyone is naming their div tags and whatnot, so what's the controller(?) doing to hook all these components in on the final page?? Note: This doesn't just apply to facebook - any company that has separate teams working on separate components has some logic that helps them out. EDIT: Thanks all for the responses, unfortunately I still haven't really found what I'm looking for - when you check out the source code (granted its minified), the divs have UIDs, my guess is that there is a compilation process that runs through and makes each of the components unique, renaming divs and css rules.. any ideas? EDIT 2: Thanks all for contributing your thoughts - the bounty went to the highest upvoted answer. The question was designed to be vague- I think it led to a really interesting discussion. As I improve my build process, I will contribute my own thoughts and experiences. Thanks all! Matt Mueller

  • Getting all objects with a certain element inside a collection of strings with criteria API.

    - by Jens Jansson
    Hey. I'm trying to build a Hibernate Criteria query to find entities that have a specific element inside a collection. We can take as an example a Book -object that looks like this: public class Book { private Long id; private String title; private Set<String> authors = new HashSet<String>(); } The entity is mapped like this: <class name="Book" table="Book"> <id name="id" column="BOOK_ID"> <generator class="native"/> </id> <property name="title"/> <set name="authors" table="Book_Authors"> <key column="BOOK_ID"/> <element type="string" column="AUTHORS"/> </set> </class> Now I would like to find out which books are written by Matt. With pure SQL I can do a query like this: String author = "Matt"; String query = "SELECT * FROM Book " + "WHERE BOOK_ID IN " + "(SELECT BOOK_ID FROM Book_Authors " + "WHERE authors = :author )"; List<Book> result = session.createSQLQuery(query) .addEntity(Book.class) .setParameter("author", author) .list(); This works all good and well, and I get out all books that Matt has been a part of writing. The project I work in, however, uses the Criteria API instead of raw SQL, and I haven't found a way to express the same query in that form. I've taken a look on the Restrictions API and the closest I've found is Restions.in(propertyName, collection) but that works the other way around (one value in object, many values to match against). Any ideas?

  • HTML5 Semantics - H1 or H2 for ARTICLE titles in a SECTION

    - by Matt
    It's my understanding (based from this chapter of Dive into HTML5: http://goo.gl/9zliD) that it can be considered semantically appropriate to use H1 tags in multiple areas of the page, as a method of setting the most important title for that particular content. If I'm using this methodology, and I have a SECTION which I've assigned an H1 of 'Articles', should I use H1 or H2 to define the titles for ARTICLEs in that SECTION? This is a bit confusing to me as the article titles are the most important heading for their ARTICLE, but are also 'children' of the SECTION's title. Example code: <section class="article-list"> <header> <h1>Articles</h1> </header> <article> <header> <h2>Article Title</h2> <time datetime="201-02-01">Today</time> </header> <p>Article text...</p> </article> <article> <header> <h2>Article Title</h2> <time datetime="2011-01-31">Yesterday</time> </header> <p>Article text...</p> </article> <article> <header> <h2>Article Title</h2> <time datetime="2011-01-30">The Day Before Yesterday</time> </header> <p>Article text...</p> </article> </section>

  • The HTG Guide to Using a Bluetooth Keyboard with Your Android Device

    - by Matt Klein
    Android devices aren’t usually associated with physical keyboards. But, since Google is now bundling their QuickOffice app with the newly-released Kit-Kat, it appears inevitable that at least some Android tablets (particularly 10-inch models) will take on more productivity roles. In recent years, physical keyboards have been rendered obsolete by swipe style input methods such as Swype and Google Keyboard. Physical keyboards tend to make phones thick and plump, and that won’t fly today when thin (and even flexible and curved) is in vogue. So, you’ll be hard-pressed to find smartphone manufacturers launching new models with physical keyboards, thus rendering sliders to a past chapter in mobile phone evolution. It makes sense to ditch the clunky keyboard phone in favor of a lighter, thinner model. You’re going to carry around in your pocket or purse all day, why have that extra bulk and weight? That said, there is sound logic behind pairing tablets with keyboards. Microsoft continues to plod forward with its Surface models, and while critics continue to lavish praise on the iPad, its functionality is obviously enhanced and extended when you add a physical keyboard. Apple even has an entire page devoted specifically to iPad-compatible keyboards. But an Android tablet and a keyboard? Does such a thing even exist? They do actually. There are docking keyboards and keyboard/case combinations, there’s the Asus Transformer family, Logitech markets a Windows 8 keyboard that speaks “Android”, and these are just to name a few. So we know that keyboard products that are designed to work with Android exist, but what about an everyday Bluetooth keyboard you might use with Windows or OS X? How-To Geek wanted look at how viable it is to use such a keyboard with Android. We conducted some research and examined some lists of Android keyboard shortcuts. Most of what we found was long outdated. Many of the shortcuts don’t even apply anymore, while others just didn’t work. Regardless, after a little experimentation and a dash of customization, it turns out using a keyboard with Android is kind of fun, and who knows, maybe it will catch on. Setting things up Setting up a Bluetooth keyboard with Android is very easy. First, you’ll need a Bluetooth keyboard and of course an Android device, preferably running version 4.1 (Jelly Bean) or higher. For our test, we paired a second-generation Google Nexus 7 running Android 4.3 with a Samsung Series 7 keyboard. In Android, enable Bluetooth if it isn’t already on. We’d like to note that if you don’t normally use Bluetooth accessories and peripherals with your Android device (or any device really), it’s best practice to leave Bluetooth off because, like GPS, it drains the device’s battery more quickly. To enable Bluetooth, simply go to “Settings” -> “Bluetooth” and tap the slider button to “On”. To set up the keyboard, make sure it is on and then tap “Bluetooth” in the Android settings. On the resulting screen, your Android device should automatically search for and hopefully find your keyboard. If you don’t get it right the first time, simply turn the keyboard on again and then tap “Search for Devices” to try again. If it still doesn’t work, make sure you have fresh batteries and the keyboard isn’t paired to another device. If it is, you will need to unpair it before it will work with your Android device (consult your keyboard manufacturer’s documentation or Google if you don’t know how to do this). When Android finds your keyboard, select it under “Available Devices” … … and you should be prompted to type in a code: If successful, you will see that device is now “Connected” and you’re ready to go. If you want to test things out, try pressing the “Windows” key (“Apple” or “Command”) + ESC, and you will be whisked to your Home screen. So, what can you do? Traditional Mac and Windows users know there’s usually a keyboard shortcut for just about everything (and if there isn’t, there’s all kinds of ways to remap keys to do a variety of commands, tasks, and functions). So where does Android fall in terms of baked-in keyboard commands? There answer to that is kind of enough, but not too much. There are definitely established combos you can use to get around, but they aren’t clear and there doesn’t appear to be any one authority on what they are. Still, there is enough keyboard functionality in Android to make it a viable option, if only for those times when you need to get something done (long e-mail or important document) and an on-screen keyboard simply won’t do. It’s important to remember that Android is, and likely always will be a touch-first interface. That said, it does make some concessions to physical keyboards. In other words, you can get around Android fairly well without having to lift your hands off the keys, but you will still have to tap the screen regularly, unless you add a mouse. For example, you can wake your device by tapping a key rather than pressing its power button. However, if your device is slide or pattern-locked, then you’ll have to use the touchscreen to unlock it – a password or PIN however, works seamlessly with a keyboard – other things like widgets and app controls and features, have to be tapped. You get the idea. Keyboard shortcuts and navigation As we said, baked-in keyboard shortcut combos aren’t necessarily abundant nor apparent. The one thing you can always do is search. Any time you want to Google something, start typing from the Home screen and the search screen will automatically open and begin displaying results. Other than that, here is what we were able to figure out: ESC = go back CTRL + ESC = menu CTRL + ALT + DEL = restart (no questions asked) ALT + SPACE = search page (say “OK Google” to voice search) ALT + TAB (ALT + SHIFT + TAB) = switch tasks Also, if you have designated volume function keys, those will probably work too. There’s also some dedicated app shortcuts like calculator, Gmail, and a few others: CMD + A = calculator CMD + C = contacts CMD + E = e-mail CMD + G = Gmail CMD + L = Calendar CMD + P = Play Music CMD + Y = YouTube Overall, it’s not a long comprehensive list and there’s no dedicated keyboard combos for the full array of Google’s products. Granted, it’s hard to imagine getting a lot of mileage out of a keyboard with Maps but with something like Keep, you could type out long, detailed lists on your tablet, and then view them on your smartphone when you go out shopping. You can also use the arrow keys to navigate your Home screen over shortcuts and open the app drawer. When something on the screen is selected, it will be highlighted in blue. Press “Enter” to open your selection. Additionally, if an app has its own set of shortcuts, e.g. Gmail has quite a few unique shortcuts to it, as does Chrome, some – though not many – will work in Android (not for YouTube though). Also, many “universal” shortcuts such as Copy (CTRL + C), Cut (CTRL + X), Paste (CTRL + V), and Select All (CTRL + A) work where needed – such as in instant messaging, e-mail, social media apps, etc. Creating custom application shortcuts What about custom shortcuts? When we were researching this article, we were under the impression that it was possible to assign keyboard combinations to specific apps, such as you could do on older Android versions such as Gingerbread. This no long seems to be the case and nowhere in “Settings” could we find a way to assign hotkey combos to any of our favorite, oft-used apps or functions. If you do want custom keyboard shortcuts, what can you do? Luckily, there’s an app on Google Play that allows you to, among other things, create custom app shortcuts. It is called External Keyboard Helper (EKH) and while there is a free demo version, the pay version is only a few bucks. We decided to give EKH a whirl and through a little experimentation and finally reading the developer’s how-to, we found we could map custom keyboard combos to just about anything. To do this, first open the application and you’ll see the main app screen. Don’t worry about choosing a custom layout or anything like that, you want to go straight to the “Advanced settings”: In the “Advanced settings” select “Application shortcuts” to continue: You can have up to 16 custom application shortcuts. We are going to create a custom shortcut to the Facebook app. We choose “A0”, and from the resulting list, Facebook. You can do this for any number of apps, services, and settings. As you can now see, the Facebook app has now been linked to application-zero (A0): Go back to the “Advanced settings” and choose “Customize keyboard mappings”: You will be prompted to create a custom keyboard layout so we choose “Custom 1”: When you choose to create a custom layout, you can do a great many more things with your keyboard. For example, many keyboards have predefined function (Fn) keys, which you can map to your tablet’s brightness controls, toggle WiFi on/off, and much more. A word of advice, the application automatically remaps certain keys when you create a custom layout. This might mess up some existing keyboard combos. If you simply want to add some functionality to your keyboard, you can go ahead and delete EKH’s default changes and start your custom layout from scratch. To create a new combo, select “Add new key mapping”: For our new shortcut, we are going to assign the Facebook app to open when we key in “ALT + F”. To do this, we press the “F” key while in the “Scancode” field and we see it returns a value of “33”. If we wanted to use a different key, we can press “Change” and scan another key’s numerical value. We now want to assign the “ALT” key to application “A0”, previously designated as the Facebook app. In the “AltGr” field, we enter “A0” and then “Save” our custom combo. And now we see our new application shortcut. Now, as long as we’re using our custom layout, every time we press “ALT + F”, the Facebook app will launch: External Keyboard Helper extends far beyond simple application shortcuts and if you are looking for deeper keyboard customization options, you should definitely check it out. Among other things, EKH also supports dozens of languages, allows you to quickly switch between layouts using a key or combo, add up to 16 custom text shortcuts, and much more! It can be had on Google Play for $2.53 for the full version, but you can try the demo version for free. More extensive documentation on how to use the app is also available. Android? Keyboard? Sure, why not? Unlike traditional desktop operating systems, you don’t need a physical keyboard and mouse to use a mobile operating system. You can buy an iPad or Nexus 10 or Galaxy Note, and never need another accessory or peripheral – they work as intended right out of the box. It’s even possible you can write the next great American novel on one these devices, though that might require a lot of practice and patience. That said, using a keyboard with Android is kind of fun. It’s not revelatory but it does elevate the experience. You don’t even need to add customizations (though they are nice) because there are enough existing keyboard shortcuts in Android to make it usable. Plus, when it comes to inputting text such as in an editor or terminal application, we fully advocate big, physical keyboards. Bottom line, if you’re looking for a way to enhance your Android tablet, give a keyboard a chance. Do you use your Android device for productivity? Is a physical keyboard an important part of your setup? Do you have any shortcuts that we missed? Sound off in the comments and let us know what you think.

  • Need help with PHP web app bootstrapping error potentially related to Zend [migrated]

    - by Matt Shepherd
    I am trying to get a program called OpenFISMA running on an Ubuntu AMI in AWS. The app is not really coded on the Ubuntu platform, but I am in my comfort zone there, and have tried both CentOS and OpenSUSE (both are sort of "native" for the app) for getting it working with the same or worse results. So, why not just get it working on Ubuntu? Anyway, the app is found here: www.openfisma.org and an install guide is found here: https://openfisma.atlassian.net/wiki/display/030100/Installation+Guide The install guide kind of sucks. It doesn't list dependencies in any coherent way or provide much of any detail (does not even mention Zend once on the entire page) so I've done a lot of work to divine the information I do have. This page provided some dependency inf (though again, Zend is not mentioned once): https://openfisma.atlassian.net/wiki/display/PUBLIC/RPM+Management#RPMManagement-BasicOverviewofRPMPackages Anyway, I got all the way through the install (so far as I could reconstruct it). I am going to the login page for the first time, and there should be some sort of bootstrapping occurring when I load the page. (I am not a programmer so I have no idea what it is doing there.) Anyway, I get a message on the web page that says: "An exception occurred while bootstrapping the application." So, then I go look in /var/www/data/logs/php.log and find this message: [22-Oct-2013 17:29:18 UTC] PHP Fatal error: Uncaught exception 'Zend_Exception' with message 'No entry is registered for key 'Zend_Log'' in /var/www/library/Zend/Registry.php:147 Stack trace: #0 /var/www/public/index.php(188): Zend_Registry::get('Zend_Log') #1 {main} thrown in /var/www/library/Zend/Registry.php on line 147 This occurs every time I load the page. I gather there is an issue related to registering the Zend_Log variable in the Zend registry, but other than that I really have no idea what to do about it. Am I missing a package that it needs, or is this app not coded to register the variables properly? I have no clue. Any help is greatly appreciated.

  • [GEEK SCHOOL] Network Security 1: Securing User Accounts and Passwords in Windows

    - by Matt Klein
    This How-To Geek School class is intended for people who want to learn more about security when using Windows operating systems. You will learn many principles that will help you have a more secure computing experience and will get the chance to use all the important security tools and features that are bundled with Windows. Obviously, we will share everything you need to know about using them effectively. In this first lesson, we will talk about password security; the different ways of logging into Windows and how secure they are. In the proceeding lesson, we will explain where Windows stores all the user names and passwords you enter while working in this operating systems, how safe they are, and how to manage this data. Moving on in the series, we will talk about User Account Control, its role in improving the security of your system, and how to use Windows Defender in order to protect your system from malware. Then, we will talk about the Windows Firewall, how to use it in order to manage the apps that get access to the network and the Internet, and how to create your own filtering rules. After that, we will discuss the SmartScreen Filter – a security feature that gets more and more attention from Microsoft and is now widely used in its Windows 8.x operating systems. Moving on, we will discuss ways to keep your software and apps up-to-date, why this is important and which tools you can use to automate this process as much as possible. Last but not least, we will discuss the Action Center and its role in keeping you informed about what’s going on with your system and share several tips and tricks about how to stay safe when using your computer and the Internet. Let’s get started by discussing everyone’s favorite subject: passwords. The Types of Passwords Found in Windows In Windows 7, you have only local user accounts, which may or may not have a password. For example, you can easily set a blank password for any user account, even if that one is an administrator. The only exception to this rule are business networks where domain policies force all user accounts to use a non-blank password. In Windows 8.x, you have both local accounts and Microsoft accounts. If you would like to learn more about them, don’t hesitate to read the lesson on User Accounts, Groups, Permissions & Their Role in Sharing, in our Windows Networking series. Microsoft accounts are obliged to use a non-blank password due to the fact that a Microsoft account gives you access to Microsoft services. Using a blank password would mean exposing yourself to lots of problems. Local accounts in Windows 8.1 however, can use a blank password. On top of traditional passwords, any user account can create and use a 4-digit PIN or a picture password. These concepts were introduced by Microsoft to speed up the sign in process for the Windows 8.x operating system. However, they do not replace the use of a traditional password and can be used only in conjunction with a traditional user account password. Another type of password that you encounter in Windows operating systems is the Homegroup password. In a typical home network, users can use the Homegroup to easily share resources. A Homegroup can be joined by a Windows device only by using the Homegroup password. If you would like to learn more about the Homegroup and how to use it for network sharing, don’t hesitate to read our Windows Networking series. What to Keep in Mind When Creating Passwords, PINs and Picture Passwords When creating passwords, a PIN, or a picture password for your user account, we would like you keep in mind the following recommendations: Do not use blank passwords, even on the desktop computers in your home. You never know who may gain unwanted access to them. Also, malware can run more easily as administrator because you do not have a password. Trading your security for convenience when logging in is never a good idea. When creating a password, make it at least eight characters long. Make sure that it includes a random mix of upper and lowercase letters, numbers, and symbols. Ideally, it should not be related in any way to your name, username, or company name. Make sure that your passwords do not include complete words from any dictionary. Dictionaries are the first thing crackers use to hack passwords. Do not use the same password for more than one account. All of your passwords should be unique and you should use a system like LastPass, KeePass, Roboform or something similar to keep track of them. When creating a PIN use four different digits to make things slightly harder to crack. When creating a picture password, pick a photo that has at least 10 “points of interests”. Points of interests are areas that serve as a landmark for your gestures. Use a random mixture of gesture types and sequence and make sure that you do not repeat the same gesture twice. Be aware that smudges on the screen could potentially reveal your gestures to others. The Security of Your Password vs. the PIN and the Picture Password Any kind of password can be cracked with enough effort and the appropriate tools. There is no such thing as a completely secure password. However, passwords created using only a few security principles are much harder to crack than others. If you respect the recommendations shared in the previous section of this lesson, you will end up having reasonably secure passwords. Out of all the log in methods in Windows 8.x, the PIN is the easiest to brute force because PINs are restricted to four digits and there are only 10,000 possible unique combinations available. The picture password is more secure than the PIN because it provides many more opportunities for creating unique combinations of gestures. Microsoft have compared the two login options from a security perspective in this post: Signing in with a picture password. In order to discourage brute force attacks against picture passwords and PINs, Windows defaults to your traditional text password after five failed attempts. The PIN and the picture password function only as alternative login methods to Windows 8.x. Therefore, if someone cracks them, he or she doesn’t have access to your user account password. However, that person can use all the apps installed on your Windows 8.x device, access your files, data, and so on. How to Create a PIN in Windows 8.x If you log in to a Windows 8.x device with a user account that has a non-blank password, then you can create a 4-digit PIN for it, to use it as a complementary login method. In order to create one, you need to go to “PC Settings”. If you don’t know how, then press Windows + C on your keyboard or flick from the right edge of the screen, on a touch-enabled device, then press “Settings”. The Settings charm is now open. Click or tap the link that says “Change PC settings”, on the bottom of the charm. In PC settings, go to Accounts and then to “Sign-in options”. Here you will find all the necessary options for changing your existing password, creating a PIN, or a picture password. To create a PIN, press the “Add” button in the PIN section. The “Create a PIN” wizard is started and you are asked to enter the password of your user account. Type it and press “OK”. Now you are asked to enter a 4-digit pin in the “Enter PIN” and “Confirm PIN” fields. The PIN has been created and you can now use it to log in to Windows. How to Create a Picture Password in Windows 8.x If you log in to a Windows 8.x device with a user account that has a non-blank password, then you can also create a picture password and use it as a complementary login method. In order to create one, you need to go to “PC settings”. In PC Settings, go to Accounts and then to “Sign-in options”. Here you will find all the necessary options for changing your existing password, creating a PIN, or a picture password. To create a picture password, press the “Add” button in the “Picture password” section. The “Create a picture password” wizard is started and you are asked to enter the password of your user account. You are shown a guide on how the picture password works. Take a few seconds to watch it and learn the gestures that can be used for your picture password. You will learn that you can create a combination of circles, straight lines, and taps. When ready, press “Choose picture”. Browse your Windows 8.x device and select the picture you want to use for your password and press “Open”. Now you can drag the picture to position it the way you want. When you like how the picture is positioned, press “Use this picture” on the left. If you are not happy with the picture, press “Choose new picture” and select a new one, as shown during the previous step. After you have confirmed that you want to use this picture, you are asked to set up your gestures for the picture password. Draw three gestures on the picture, any combination you wish. Please remember that you can use only three gestures: circles, straight lines, and taps. Once you have drawn those three gestures, you are asked to confirm. Draw the same gestures one more time. If everything goes well, you are informed that you have created your picture password and that you can use it the next time you sign in to Windows. If you don’t confirm the gestures correctly, you will be asked to try again, until you draw the same gestures twice. To close the picture password wizard, press “Finish”. Where Does Windows Store Your Passwords? Are They Safe? All the passwords that you enter in Windows and save for future use are stored in the Credential Manager. This tool is a vault with the usernames and passwords that you use to log on to your computer, to other computers on the network, to apps from the Windows Store, or to websites using Internet Explorer. By storing these credentials, Windows can automatically log you the next time you access the same app, network share, or website. Everything that is stored in the Credential Manager is encrypted for your protection.

  • How can I learn to effectively write Pythonic code?

    - by Matt Fenwick
    I'm tired of getting downvoted and/or semi-rude comments on my Python answers, saying things like "this isn't Pythonic" or "that's not the Python way of doing things". To clarify, I'm not tired of getting corrected and downvoted, and I'm not tired of being wrong: I'm tired of feeling like there's a whole field of Python that I know nothing about, and seems to be implicit knowledge of experienced Python programmers. Doing a google search for "Pythonic" reveals a wide range of interpretations. The wikipedia page says: A common neologism in the Python community is pythonic, which can have a wide range of meanings related to program style. To say that code is pythonic is to say that it uses Python idioms well, that it is natural or shows fluency in the language. Likewise, to say of an interface or language feature that it is pythonic is to say that it works well with Python idioms, that its use meshes well with the rest of the language. It also discusses the term "unpythonic": In contrast, a mark of unpythonic code is that it attempts to write C++ (or Lisp, Perl, or Java) code in Python—that is, provides a rough transcription rather than an idiomatic translation of forms from another language. The concept of pythonicity is tightly bound to Python's minimalist philosophy of readability and avoiding the "there's more than one way to do it" approach. Unreadable code or incomprehensible idioms are unpythonic. I suspect one way to learn the Pythonic way is just to program in Python a whole bunch. But I bet I could write a bunch of crap and not improve that much without some guidance, whereas a good resource might speed up the learning process significantly. PEP 8 might be exactly what I'm looking for, or maybe not. I'm not sure; on the one hand it covers a lot of ground, but on the other hand, I feel like it's more suited as a reference for knowledgeable programmers than a tutorial for fresh 'uns. How do I get my foot in the Pythonic/Python way of doing things door?

  • Dealing with a fundamental design flaw when you're new to the project

    - by Matt Phillips
    I've just started working on an open source project with around 30 developers in it. I'm working on fixing some of the bugs as a way to get into the "loop" and become a regular committer to the project. The problem is I think I've uncovered a fundamental design flaw that's causing one of the bugs I'm working on. But I feel like if I blast this on the mailing list I'm going to come off as arrogant, and some of the discussions I've had about the issue are butting heads with some of the people. How should I go about this?

  • What makes a Software Craftsman?

    - by Liam McLennan
    At the end of my visit to 8th Light Justin Martin was kind enough to give me a ride to the train station; for my train back to O’Hare. Just before he left he asked me an interesting question which I then posted to twitter: Liam McLennan: . @JustinMartinM asked what I think is the most important attributes of craftsmen. I said, "desire to learn and humility". What's yours? 6:25 AM Apr 17th via TweetDeck several people replied with excellent contributions: Alex Hung: @liammclennan I think kaizen sums up craftmanship pretty well, which is almost same as yours Steve Bohlen: @alexhung @liammclennan those are both all about saying "knowing what you don't know and not being afraid to go learn it" (and I agree!) Matt Roman: @liammclennan @JustinMartinM a tempered compulsion for constant improvement, and an awareness of what needs improving. Justin Martin: @mattroman @liammclennan a faculty for asking challenging questions, and a persistence to battle through difficult obstacles barring growth I thought this was an interesting conversation, and I would love to see other people contribute their opinions. My observation is that Alex, Steve, Matt and I seem to have essentially the same answer in different words. It is also interesting to note (as Alex pointed out) that these definitions are very similar to Alt.NET and the lean concept of kaizen.

  • Initial Review - Mastering Unreal Technology I: Introduction to Level Design with Unreal Engine 3

    - by Matt Christian
    Recently I purchased 3 large volumes on using the Unreal 3 Engine to create levels and custom games.  This past weekend I cracked the spine of the first and started reading.  Here are my early impressions (I'm ~250 pages into it, with appendices it's about 900). Pros Interestingly, the book starts with an overview of the Unreal engines leading up to Unreal 3 (including Gears of War) and follows with some discussion on planning a mod and what goes into the game development process.  This is nice for an intro to the book and is much preferred rather than a simple chapter detailing what is on the included CD, how to install and setup UnrealEd, etc...  While the chapter on Unreal history and planning can be considered 'fluff', it's much less 'fluffy' than most books provide. I need to mention one thing here that is pretty crucial in the way I'm going to continue reviewing this book.  Most technical books like this are used as a shelf reference; as a thick volume you use for looking up techniques every now and again.  Even so, I prefer reading from cover to cover, including chapters I may already be knowledgable on (I'm sure this is typical for most people).  If there was a chapter on installing UnrealEd (the previously mentioned 'fluff'), I would probably force myself to read it, even though I've installed the game and engine multiple times on different systems. Chapter 3 is where we really get to the introduction piece of UnrealEd, creating your first basic level.  This large chapter details creating two small rooms, adding static meshes, adding lighting, creating and adding particle emitters, creating a door that animates with Unreal Matinee and Kismet, static meshes with physics, and other little additions to make your level look less beginner.  This really is a chapter that overviews the entire rest of the book, as each chapter following details the creation and intermediate usages of Static Meshes, Materials, Lighting, etc... One other very nice part to this book is the way the tutorials are setup.  Each tutorial builds off the previous and all are step-by-step.  If you haven't completed one yet, you can find all the starting files on the CD that comes with the book. Cons While the description of the overview chapter (Chapter 3) is fresh in your mind, let me start the cons by saying this chapter is setup extremely confusing for the noob.  At one point, you end up creating a door mesh and setting it up as a InteropMesh so that it is ready to be animated, only to switch to particles and spend a good portion of time working on a different piece of the level.  Yes, this is actually how I develop my levels (jumping back and forth), though it's very odd for a book to jump out of sequence. The next item might be a positive or a negative depending on your skill level with UnrealEd.  Most of the introduction to the editor layout is found in one of the Appendices instead of before Chapter 3.  For new readers, this might lead to confusion as Appendix A would typically be read between Chapter 2 and 3.  However, this is a positive for those with some experience in UnrealEd as they don't have to force themselves through a 'learn every editor button' chapter.  I'm listing this in the Cons section as the book is 'Introduction to...' and is probably going to be directed toward a lot of very beginner developers. Finally, there's a lack of general description to a lot of the underlying engine and what each piece in UnrealEd is or does.  Sometimes you'll be performing Tutorial after Tutorial with barely a paragraph in between describing ANY of what you've just done.  Tutorial 1.1 Step 6 says to press Button X, so you do.  But why?  This is in part a problem with the structure of the tutorials rather than the content of the book.  Since the tutorials are so focused on a step-by-step (or procedural) description of a process, you learn the process and not why you're doing that.  For example, you might learn how to size a material to a surface, but will only learn what buttons to press and not what each one does. This becomes extremely apparent in the chapter on Static Meshes as most of the chapter is spent in 3D Studio Max.  Since there are books on 3DSM and modelling, the book really only tells you the steps and says to go grab a book on modelling if you're really interested in 3DSM.  Again, I've learned the process to develop my own meshes in 3DSM, but I don't know the why behind the steps. Conclusion So far the book is very good though I would have a hard time recommending it to a complete beginner.  I would suggest anyone looking at this book (obviously including the other 2, more advanced volumes) to pick up a copy of UDK or Unreal 3 (available online or via download services such as Steam) and watch some online tutorials and play with it first.  You'll find plenty of online videos available that were created by the authors and may suit as a better introduction to the editor.

  • Retro Video Game Collection

    - by Matt Christian
    Recently I've decided, in true nerd fashion, to collect either comic books or video games.  Considering I'm much more versed in the technological arts and not in ACTUAL art, I thought collecting old video games would be an interesting venture.  After all, I am a self-described compulsive shopper (my bank statement at the end of the month has a purchase every few days).  (Don't worry, I'm not in debt and still pay my bills on time!) I went to a local video game store in Stevens Point called Gaming Generations which is a neat little shop with loads of old games for great prices.  For example, any NES cartridge on the shelf (not behind glass) is, at most, $4.99 with the cheaper ones around $1.99.  During my first round at GG, I picked up the following: NES: - Fester's Quest - Adventures of Link (Zelda 2, grey cart) - Little Nemo - Total Recall - The Goonies 2 PSX: - Galerians N64: - Mission: Impossible - Hybrid Heaven I was a little cautious, would I even like collecting old games?  As soon as I popped a few of those games in I knew right away the answer was an astounding YES!  Not only is it fun to bring back memories of all these old games, but searching for them in stores is also a blast and saying 'I have that one, I need the second one.' After finding such joy in buying these games, I decided to go search through 4-5 stores in Wausau for old games as well.  While the prices were a bit higher and selection smaller, the search was still fun.  I found the following: NES: - Maniac Mansion - T&C Surf - Chip N Dale: Rescue Rangers - TMNT (the first one) - Mission: Impossible N64: - Turok - Turok 2 Genesis: - Sonic the Hedgehog Dreamcast: - Shenmue And I found a Gamegear for $5!  Now I just need to find games for it... Tonight I will go on one more small expedition into the used, once again stopping at GG and another second hand store to see if I can find any items for my collection.

  • In-Application Support Made Easier

    - by matt.hicks
    With the availability of Oracle UPK 3.6.1 and Enablement Service Pack 1 for Oracle UPK 3.6.1 (Oracle Support login required for both), there are quite a few changes for content admins to absorb. In addition to the support added for dozens of application releases, patches and new target applications, we've also added features to make implementing and using In-Application Support even easier. First, the old Help Menu Integration Guides have been updated and combined into a single In-Application Support Guide. If you integrate UPK content for user assistance, or if you're interested in doing so, read the new guide! It covers all the integration steps, including a section on the new In-Application Support Configuration Utility. If you've integrated content in multiple languages, or if you've ever had to make configuration changes for UPK Help Integration, then you know how cumbersome it was to manually edit javascript files. No longer! The Player now includes a configuration utility that provides a web browser interface for setting all In-Application Support options. From the main screen, you see a list of applications covered by the published content. Clicking on an application name takes you to the edit configuration screen where you can set all Player options for that application. No more digging through the Player folders to find the right javascript file to edit. No complicated javascript syntax to make changes. And with Enablement Service Pack 1 we've added a new feature we're calling the Tabbed Gateway. The Tabbed Gateway is a top-level navigation bar for Help Integration. And all tabs, links, and text are controlled with the Configuration Utility... I think the Tabbed Gateway is a really cool and exciting feature for content launch. I can't wait to hear how your ideas for how to use it for your content. Let me know in comments or email!
