  • Search Engine Optimization For Beginners

    Learning about the SEO techniques can be scary and a bit overwhelming to say the least. If you do not know anything about SEO now is the time to learn, before trying to do it with just a little bit of knowledge, you will fail if you do it that way.

  • Why’s (Poignant) Guide to Ruby

    - by Ben Griswold
    You’re familiar with O’Reilly’s brilliant Head First Series, right?  Great.  Then you know how every book begins with an explanation of the Head First teaching style and you know the teaching format which Kathy Sierra and Bert Bates developed is based on research in cognitive science, neurobiology and educational psychology and it’s all about making learning visual and conversational and attractive and emotional and it’s highly effective.  Anyway, it’s a great series and you should read every last one of the books. Moving on… I’ve been wanting to learn more about Ruby and Why’s (Poignant) Guide to Ruby has been on my reading list for a while and there was talk about cartoon foxes and other silliness and I figured Why’s (Poignant) Guide to Ruby probably takes the same unorthodox teaching style as the Head First books – and that’s great – so I read the book, in piecemeal, over the last couple of weeks and, well, I figured wrong. Now having read the book, here’s my take on Why’s (Poignant) Guide – it’s very creative and clever and it does a darn good job of introducing one to Ruby.  If you’re interested in Ruby or simply interested, the online book is worth your time.  If you’re thinking (like me) that cartoon foxes will be doing the teaching, that’s simple not the case.  However, the cartoons and the random stories in the sidebar may serve a purpose. Unlike the Head First books where images and captions are used to further explain the teachings, the cartoons and stories in Why’s Guide serve as intermission and offer your brain a brief moment of rest before the next Ruby concept is explained.  It’s not a bad strategy, but definitely not as effective as the Head First techniques.

  • New technical product guide for Sun Ray clients

    - by Jaap
    In the Oracle online documentation system a new Sun Ray clients Technical Product guide has been published. The document provides detailed information about the similarities and differences between the three Sun Ray client hardware models: Sun Ray 3, Sun Ray 3 plus and Sun Ray 3i. From the description of the Technical Product guide I want to quote the following section: "......Since Sun Ray 3 Series Clients have no local operating system and require no local management, they eliminate the complexity, expenses, and security vulnerabilities associated with other thin client and PC solutions. ......" This is always one of the great advantages of Sun Ray clients compared to other thin clients (which are actually low-fat PCs where you have to manage thin client OS images). The guide lists the features and technical specifications of the Sun Ray Client such as number of ports, chassis, graphics, network interfaces, power supply, operating conditions, MTBF, reliability, and other standards. The guide also contains a separate chapter about environmental data. As you may know, the Sun Ray 3 Series clients are designed specifically to be sensitive to a spectrum of environmental concerns and standards, from materials to manufacturing processes to shipping, operation, and end of life. The Sun Ray 3 Series clients complies to environmental standards and certifications such as Energy Star 5.0, EPEAT, WEEE and RoHS (see the Oracle policy for RoHS and REACH).

  • XNA Guide text input - maximum length

    - by simonalexander2005
    so I am using Guide.BeginShowKeyboardInput to get the user to enter their username. I would like this to be limited to 20 characters, and it seems to break expected behaviour to let them input whatever they like and trim it later - so how would I go about limiting what they can input in the text box itself? I have the following code: public string GetKeyboardInput(string title, string description, string defaultText, int maxLength) { if (input.CheckCancel()) { useKeyboardResult = false; KeyboardResult = null; } if (KeyboardResult == null && !Guide.IsVisible) { KeyboardResult = Guide.BeginShowKeyboardInput(PlayerIndex.One, title, description, defaultText, null, null); useKeyboardResult = true; } else if (KeyboardResult != null && KeyboardResult.IsCompleted) { string result = Guide.EndShowKeyboardInput(KeyboardResult); KeyboardResult = null; if (result == null) { useKeyboardResult = false; return null; } if (useKeyboardResult) { KeyboardResult = null; return result; } } else //the user is still entering inputs { } return null; } I assume the code I need would go in that final, empty else{} block, but I can't see any way to do this. Does anyone know how?

  • Why Java as a First Language?

    - by dsimcha
    Why is Java so popular as a first language to teach beginners? To me it seems like a terrible choice: It's statically typed. Static typing isn't useful unless you care a lot about either performance or scaling to large projects. It requires tons of boilerplate to get the simplest code up and running. Try explaining "Hello, world" to someone who's never programmed before. It only handles the middle levels of abstraction well and is single-paradigm, thus leaving out a lot of important concepts. You can't program at a very low level (pointers, manual memory management) or a very high level, (metaprogramming, macros) in it. In general, Java's biggest strength (i.e. the reason people use it despite the shortcomings of the language per se) is its libraries and tool support, which is probably the least important attribute for a beginner language. In fact, while useful in the real world these may negatives from a pedagogical perspective as they can discourage learning to write code from scratch.

  • What features are important in a programming language for young beginners?

    - by NoMoreZealots
    I was talking with some of the mentors in a local robotics competition for 7th and 8th level kids. The robot was using PBASIC and the parallax Basic Stamp. One of the major issues was this was short term project that required building the robot, teaching them to program in PBASIC and having them program the robot. All in only 2 hours or so a week over a couple months. PBASIC is kinda nice in that it has built in features to do everything, but information overload is possible to due this. My thought are simplicity is key. When you have kids struggling to grasp: if X>10 then <DOSOMETHING> There is not much point in throwing "proper" object oriented programming at them. What are the essentials needed to foster an interest in programming?

  • Why&rsquo;s Poignant Guide To Ruby

    - by Liam McLennan
    According to Wikipedia, “why the lucky stiff was the persona of an anonymous, but prolific writer, cartoonist, musician, artist, and computer programmer”. He looks a bit like Jack Black. His book, Why’s Poignant Guide to Ruby, is a classic, though it can be hard to find since Why disappeared. If you want to learn the Ruby programming language I highly recommend Why’s Poignant Guide to Ruby. I am including a link here so that others who search for it may find it more easily.

  • Guide to Downloading Oracle Fusion Middleware 11g Products

    - by Daniel Mortimer
    IntroductionThe idea of writing a blog about downloading software seems a bit strange .. right? After all, surely just give me the web download link and away I go!? Unfortunately, life is not so simple if you are a DBA or Systems Administrator tasked with staging Oracle Fusion Middleware 11g products for your chosen business technology stack. Here are the challenges: Oracle Fusion Middleware is not a single product, it is a family of products - a media pack with many many "disks" - which ones do I pick? Are the products I pick certified / supported on my chosen platform? Which download site do I use? I need to be on the latest and greatest - how do I get hold of the latest product patch set? The purpose of this blog is to give you a roadmap to get you through these challenges. Oracle Fusion Middleware 11g - A Product SuiteThe first thing to appreciate is that Oracle Fusion Middleware 11g is not a single product. It is a product suite, an umbrella label for many products. Typically you don't download the whole media pack - well not unless you want to stage 124 Parts - a total of 68 Gig  - instead you pick the pieces that are required for your chosen Middleware solution. Therefore, you need to research / understand which products are required to build your solution. In this respect, before you go looking for the software pick and persue the product guide from the table below which matches your situation:  Installing a New / Vanilla FMW 11g architecture Oracle Fusion Middleware Installation Planning Guide 11g  Upgrading Oracle Application Server 10g to FMW 11g Oracle Fusion Middleware Upgrade Planning Guide 11g  Patching an existing FMW 11g architecture Oracle Fusion Middleware Patching Guide 11g Certification Information Ok, so now you have an idea of what Fusion Middleware products you need. It's time to check whether these products are certified against your chosen platform. There are two places to find this information:My Oracle Support Certification Tab PageFigure 1.1 My Oracle Support Certification Tab Page - "Search on SOA Suite" Figure 1.2 My Oracle Support Certification Tab Page - "SOA Suite Search Result" The FMW 11g Certification Central Hub (in the format of xls spreadsheet)Figure 2: Screenshot of FMW 11g Release 1 Certification xls spreadsheet Hints / Tips: Fusion Middleware 11g certification information has only recently been added into the Certification Tab page and I think it is the more friendly way to access the information. However, due to some restrictions with the Certification Tab page interface some of the more, let's say obscure certification information, is still to be only found in the Certification spreadsheet. Be aware that to find certification information via the My Oracle Support Certification Tab page you must enter the FMW 11g product name e.g. "Oracle SOA Suite". Do NOT enter "Oracle Fusion Middleware". The certification information does not exist at this product suite level.  For example, if you are building a solution which includes Oracle SOA Suite Oracle WebCenter then you will have to look up the certification information for each product in turn.After choosing the product name, select the latest patch set version. This will not only tell you whether your chosen product is available at that patch set version but provide the certification information relevant to that version.  If the product is not available under the latest patch set version, seek the information under previous patch set versions. Important: Make a careful note of the Oracle WebLogic Server version which is certified with your chosen product and patch set version. Oracle WebLogic Server is the core component of a Oracle Fusion Middleware 11g home. It is important therefore to ensure later on that you download the version of Oracle WebLogic Server which is compatible and certified with your chosen product and patch set version.Also - sorry to state the obvious, but please do not take certification information from the screenshots above. The screenshots are only good for the time they were entered into the blog. To ensure you have the latest information, interactively look up the certification details. For more information about finding certification information, bookmark and readMy Oracle Support Certification Tool for Oracle Fusion Middleware Products [Doc ID 1368736.1]How to Find Certification Details for Oracle Application Server 10g and Oracle Fusion Middleware 11g [Doc ID 431578.1] Downloading the Software Now you should be ready to download the software. There are two download locations Oracle Software Delivery Cloud (formerly known as E-Delivery)Figure 3 - Screenshot of Fusion Middleware Download from Delivery CloudOracle Fusion Middleware Download Page on Oracle Technology NetworkFigure 4 - Screenshot of OTN Product Download Screen Hints / Tips: Your choice of download location should be primarily driven by your licensing needs. Take note of the wording on the OTN site - to quote:"The downloads below are provided for evaluators under the OTN License Agreement. Licensed customers should download their software via our Oracle Software Delivery Cloud site, which offers different license terms."However, it has to be said that the presentation of the most of the product download pages on OTN does make the job easier. The Software Delivery Cloud provides you with a flat list of the Oracle Fusion Middleware 11g media pack. You have to know what you are looking for and pick out the right pieces :-( The OTN product download pages present not only the download for the product you want but also its dependencies such as WebLogic Server and Repository Creation Utility. So, even if your licensing requirements drive you towards the cloud, it is still worthwhile checking the OTN pages if only as a guide to what you need to pick out from the flat list found on the cloud site. Latest Patch Set This is an area which may cause you confusion - especially if you are more familiar with the Oracle Application Server 10g patching story. From Patch Set 11.1.1.6 and higher, the majority of FMW 11g products (N.B there are exceptions) provide installers which can be used both to update existing FMW 11g product installs or build brand new ones. This is good news because, unless you are dealing with one of the exceptions, it means you do not have to download base software and a patch set. At the time of the writing, the two significant exceptions are: Portal/Forms/Reports/Discoverer 11g Release 1 (11.1.1.x) Identity Access Management 11g Release 1 (11.1.1.x) The other key message here is ensure you are grabbing a version of Oracle WebLogic Server which is compatible with your chosen product patch set version. Get this wrong and you will hit errors / problems at AS Instance Configuration Time.The go to place is this document - Oracle Fusion Middleware Download, Installation, and Configuration Readme FilesIn fact, this README document pretty much takes you through what I have blogged above. The only thing is you need to know which README to choose, and that's why planning your FMW 11g technology stack and viewing certification information comes into play beforehand. And Finally As the Oracle Fusion Middleware Download, Installation, and Configuration Readme Files states don't forget to check FMW 11g System Requirements FMW 11g Product Interoperability

  • LinkSys WRT54GL + AM200 in half-bridge mode - Setup guide recommendations?

    - by Peter Mounce
    I am basically looking for a good guide on how to set up my home network with this set of hardware. I need: Dynamic DNS Firewall + port-forwarding VPN Wake-on-LAN from outside firewall VOIP would be nice QoS would be nice (make torrents take lower priority to other services when those other services are happening) DHCP Wireless + WPA2 security Ability to play multiplayer computer games I am not a networking or computing neophyte, but the last time I messed with network gear was a few years ago, so am needing to dust off knowledge I kinda half have. I have read that I should be wanting to set up the AM200 in half-bridge mode, so that the WRT54GL gets the WAN IP - this sounds like a good idea, but I'd still like to be advised. I have read that the dd-wrt firmware will meet my needs (though I gather I'll need the vpn-specific build, which appears to preclude supporting VOIP), but I'm not wedded to using it.

  • NHibernate 2 Beginner's Guide Review

    - by Ricardo Peres
    OK, here's the review I promised a while ago. This is a beginner's introduction to NHibernate, so if you have already some experience with NHibernate, you will notice it lacks a lot of concepts and information. It starts with a good description of NHibernate and why would we use it. It goes on describing basic mapping scenarios having primary keys generated with the HiLo or Identity algorithms, without actually explaining why would we choose one over the other. As for mapping, the book talks about XML mappings and provides a simple example of Fluent NHibernate, comparing it to its XML counterpart. When it comes to relations, it covers one-to-many/many-to-one and many-to-many, not one-to-one relations, but only talks briefly about lazy loading, which is, IMO, an important concept. Only Bags are described, not any of the other collection types. The log4net configuration description gets it's own chapter, which I find excessive. The chapter on configuration merely lists the most common properties for configuring NHibernate, both in XML and in code. Querying only talks about loading by ID (using Get, not Load) and using Criteria API, on which a paging example is presented as well as some common filtering options (property equals/like/between to, no examples on conjunction/disjunction, however). There's a chapter fully dedicated to ASP.NET, which explains how we can use NHibernate in web applications. It basically talks about ASP.NET concepts, though. Following it, another chapter explains how we can build our own ASP.NET providers using NHibernate (Membership, Role). The available entity generators for NHibernate are referred and evaluated on a chapter of their own, the list is fine (CodeSmith, nhib-gen, AjGenesis, Visual NHibernate, MyGeneration, NGen, NHModeler, Microsoft T4 (?) and hbm2net), examples are provided whenever possible, however, I have some problems with some of the evaluations: for example, Visual NHibernate scores 5 out of 5 on Visual Studio integration, which simply does not exist! I suspect the author means to say that it can be launched from inside Visual Studio, but then, what can't? Finally, there's a chapter I really don't understand. It seems like a bag where a lot of things are thrown in, like NHibernate Burrow (which actually isn't explained at all), Blog.Net components, CSS template conversion and web.config settings related to the maximum request length for file uploads and ending with XML configuration, with the help of GhostDoc. Like I said, the book is only good for absolute beginners, it does a fair job in explaining the very basics, but lack a lot of not-so-basic concepts. Among other things, it lacks: Inheritance mapping strategies (table per class hierarchy, table per class, table per concrete class) Load versus Get usage Other usefull ISession methods First level cache (Identity Map pattern) Other collection types other that Bag (Set, List, Map, IdBag, etc Fetch options User Types Filters Named queries LINQ examples HQL examples And that's it!

  • The How-To Geek Holiday Gift Guide (Geeky Stuff We Like)

    - by The Geek
    Welcome to the very first How-To Geek Holiday Gift Guide, where we’ve put together a list of our absolute favorites to help you weed through all of the junk out there to pick the perfect gift for anybody. Though really, it’s just a list of the geeky stuff we want. We’ve got a whole range of items on the list, from cheaper gifts that most anybody can afford, to the really expensive stuff that we’re pretty sure nobody is giving us. Stocking Stuffers Here’s a couple of ideas for items that won’t break the bank. LED Keychain Micro-Light   Magcraft 1/8-Inch Rare Earth Cube Magnets Best little LED keychain light around. If they don’t need the penknife of the above item this is the perfect gift. I give them out by the handfuls and nobody ever says anything but good things about them. I’ve got ones that are years old and still running on the same battery.  Price: $8   Geeks cannot resist magnets. Jason bought this pack for his fridge because he was sick of big clunky magnets… these things are amazing. One tiny magnet, smaller than an Altoid mint, can practically hold a clipboard right to the fridge. Amazing. I spend more time playing with them on the counter than I do actually hanging stuff.  Price: $10 Lots of Geeky Mugs   Astronomy Powerful Green Laser Pointer There’s loads of fun, geeky mugs you can find on Amazon or anywhere else—and they are great choices for the geek who loves their coffee. You can get the Caffeine mug pictured here, or go with an Atari one, Canon Lens, or the Aperture mug based on Portal. Your choice. Price: $7   No, it’s not a light saber, but it’s nearly bright enough to be one—you can illuminate low flying clouds at night or just blind some aliens on your day off. All that for an extremely low price. Loads of fun. Price: $15       Geeky TV Shows and Books Sometimes you just want to relax and enjoy a some TV or a good book. Here’s a few choices. The IT Crowd Fourth Season   Doctor Who, Complete Fifth Series Ridiculous, funny show about nerds in the IT department, loved by almost all the geeks here at HTG. Justin even makes this required watching for new hires in his office so they’ll get his jokes. You can pre-order the fourth season, or pick up seasons one, two, or three for even cheaper. Price: $13   It doesn’t get any more nerdy than Eric’s pick, the fifth all-new series of Doctor Who, where the Daleks are hatching a new master plan from the heart of war-torn London. There’s also alien vampires, humanoid reptiles, and a lot more. Price: $52 Battlestar Galactica Complete Series   MAKE: Electronics: Learning Through Discovery Watch the epic fight to save the human race by finding the fabled planet Earth while being hunted by the robotic Cylons. You can grab the entire series on DVD or Blu-ray, or get the seasons individually. This isn’t your average sci-fi TV show. Price: $150 for Blu-ray.   Want to learn the fundamentals of electronics in a fun, hands-on way? The Make:Electronics book helps you build the circuits and learn how it all works—as if you had any more time between all that registry hacking and loading software on your new PC. Price: $21       Geeky Gadgets for the Gadget-Loving Geek Here’s a few of the items on our gadget list, though lets be honest: geeks are going to love almost any gadget, especially shiny new ones. Klipsch Image S4i Premium Noise-Isolating Headset with 3-Button Apple Control   GP2X Caanoo MAME/Console Emulator If you’re a real music geek looking for some serious quality in the headset for your iPhone or iPod, this is the pair that Alex recommends. They aren’t terribly cheap, but you can get the less expensive S3 earphones instead if you prefer. Price: $50-100   Eric says: “As an owner of an older version, I can say the GP2X is one of my favorite gadgets ever. Touted a “Retro Emulation Juggernaut,” GP2X runs Linux and may be the only open source software console available. Sounds too good to be true, but isn’t.” Price: $150 Roku XDS Streaming Player 1080p   Western Digital WD TV Live Plus HD Media Player If you do a lot of streaming over Netflix, Hulu Plus, Amazon’s Video on Demand, Pandora, and others, the Roku box is a great choice to get your content on your TV without paying a lot of money.  It’s also got Wireless-N built in, and it supports full 1080P HD. Price: $99   If you’ve got a home media collection sitting on a hard drive or a network server, the Western Digital box is probably the cheapest way to get that content on your TV, and it even supports Netflix streaming too. It’ll play loads of formats in full HD quality. Price: $99 Fujitsu ScanSnap S300 Color Mobile Scanner   Doxie, the amazing scanner for documents Trevor said: “This wonderful little scanner has become absolutely essential to me. My desk used to just be a gigantic pile of papers that I didn’t need at the moment, but couldn’t throw away ‘just in case.’ Now, every few weeks, I’ll run that paper pile through this and then happily shred the originals!” Price: $300   If you don’t scan quite as often and are looking for a budget scanner you can throw into your bag, or toss into a drawer in your desk, the Doxie scanner is a great alternative that I’ve been using for a while. It’s half the price, and while it’s not as full-featured as the Fujitsu, it might be a better choice for the very casual user. Price: $150       (Expensive) Gadgets Almost Anybody Will Love If you’re not sure that one of the more geeky presents is gonna work, here’s some gadgets that just about anybody is going to love, especially if they don’t have one already. Of course, some of these are a bit on the expensive side—but it’s a wish list, right? Amazon Kindle       The Kindle weighs less than a paperback book, the screen is amazing and easy on the eyes, and get ready for the kicker: the battery lasts at least a month. We aren’t kidding, either—it really lasts that long. If you don’t feel like spending money for books, you can use it to read PDFs, and if you want to get really geeky, you can hack it for custom screensavers. Price: $139 iPod Touch or iPad       You can’t go wrong with either of these presents—the iPod Touch can do almost everything the iPhone can do, including games, apps, and music, and it has the same Retina display as the iPhone, HD video recording, and a front-facing camera so you can use FaceTime. Price: $229+, depending on model. The iPad is a great tablet for playing games, browsing the web, or just using on your coffee table for guests. It’s well worth buying one—but if you’re buying for yourself, keep in mind that the iPad 2 is probably coming out in 3 months. Price: $500+ MacBook Air  The MacBook Air comes in 11” or 13” versions, and it’s an amazing little machine. It’s lightweight, the battery lasts nearly forever, and it resumes from sleep almost instantly. Since it uses an SSD drive instead of a hard drive, you’re barely going to notice any speed problems for general use. So if you’ve got a lot of money to blow, this is a killer gift. Price: $999 and up. Stuck with No Idea for a Present? Gift Cards! Yeah, you’re not going to win any “thoughtful present” awards with these, but you might just give somebody what they really want—the new Angry Birds HD for their iPad, Cut the Rope, or anything else they want. ITunes Gift Card   Amazon.com Gift Card Somebody in your circle getting a new iPod, iPhone, or iPad? You can get them an iTunes gift card, which they can use to buy music, games or apps. Yep, this way you can gift them a copy of Angry Birds if they don’t already have it. Or even Cut the Rope.   No clue what to get somebody on your list? Amazon gift cards let them buy pretty much anything they want, from organic weirdberries to big screen TVs. Yeah, it’s not as thoughtful as getting them a nice present, but look at the bright side: maybe they’ll get you an Amazon gift card and it’ll balance out. That’s the highlights from our lists—got anything else to add? Share your geeky gift ideas in the comments.
