  • Cocos2d: Moving background on update: offsett issue

    - by mm24
    working with Objective C, iOS and Cocos2d I am developing a vertical scrolling shooter game for iPhone (retina display models with 640 width x 960 height pixel resolution). My basic algorithm works as following: I create two instances of an image that has exactly 640 width x 960 height pixel of resolution, which we will call imageA and imageB I then set the two imags with exactly 480.0f of offset from each other, as the screenSize of a CCScene is set by default to 480.0f. At each update method call I move the two images by the same value. I make sure that their offsett stays to 480.0f However when running the game I see a 1 pixel height line between the two images. This literally bugs me and would like to adjust this. What am I doing wrong? This is a zoom in on the background when the "offsett line" is visible. The white line you can see divides the two background images and is not meant to exist as both images are completely black :): If I change the yPositionOfSecondElement value to 479.0f until the first loop the two images overlap correctly, but as soon as the loop starts the two images starts having an offsett of -1.0f. Here is the initialization code: -(void) init { //... screenHeight = 480.0f; yPositionOfSecondElement= screenHeight;//I tried subtracting an offsett of -1 but eventually the image would go wrong again yPositionOfFirstElement = 0.0f; loopedBackgroundImageInstanceA = [BackgroundLoopedImage loopImageForLevel:levelName]; loopedBackgroundImageInstanceA.anchorPoint = CGPointMake(0.5f, 0.0f); loopedBackgroundImageInstanceA.position = CGPointMake(160.0f, yPositionOfFirstElement); [node addChild:loopedBackgroundImageInstanceA z:zLevelBackground]; //loopedBackgroundImageInstanceA.color= ccRED; loopedBackgroundImageInstanceB = [BackgroundLoopedImage loopImageForLevel:levelName]; loopedBackgroundImageInstanceB.anchorPoint = CGPointMake(0.5f, 0.0f); loopedBackgroundImageInstanceB.position = CGPointMake(160.0f, yPositionOfSecondElement); [node addChild:loopedBackgroundImageInstanceB z:zLevelBackground]; //.... } And here is the move code called at each update: -(void) moveBackgroundSprites:(BackgroundLoopedImage*)imageA :(BackgroundLoopedImage*)imageB :(ccTime)delta { isEligibleToMove=false; //This is done to avoid rounding errors float yStep = delta * [GameController sharedGameController].currentBackgroundSpeed; NSString* formattedNumber = [NSString stringWithFormat:@"%.02f", yStep]; yStep = atof([formattedNumber UTF8String]); //First should adjust position of images [self adjustPosition:imageA :imageB]; //The can get the actual image position CGPoint posA = imageA.position; CGPoint posB = imageB.position; //Here could verify if the checksum is equal to the required difference (should be 479.0f) if (![self verifyCheckSum:posA :posB]) { CCLOG(@"does not comply A"); } //At this stage can compute the hypotetical new position CGPoint newPosA = CGPointMake(posA.x, posA.y - yStep); CGPoint newPosB = CGPointMake(posB.x, posB.y - yStep); // Reposition stripes when they're out of bounds if (newPosA.y <= -yPositionOfSecondElement) { newPosA.y = yPositionOfSecondElement; [imageA shuffle]; if (timeElapsed>=endTime && hasReachedEndLevel==FALSE) { hasReachedEndLevel=TRUE; shouldMoveImageEnd=TRUE; } } else if (newPosB.y <= -yPositionOfSecondElement) { newPosB.y = yPositionOfSecondElement; [imageB shuffle]; if (timeElapsed>=endTime && hasReachedEndLevel==FALSE) { hasReachedEndLevel=TRUE; shouldMoveImageEnd=TRUE; } } //Here should verify that the check sum is equal to 479.0f if (![self verifyCheckSum:posA :posB]) { CCLOG(@"does not comply B"); } imageA.position = newPosA; imageB.position = newPosB; //Here could verify that the check sum is equal to 479.0f if (![self verifyCheckSum:posA :posB]) { CCLOG(@"does not comply C"); } isEligibleToMove=true; } -(BOOL) verifyCheckSum:(CGPoint)posA :(CGPoint)posB { BOOL comply = false; float sum = 0.0f; if (posA.y > posB.y) { sum = posA.y - posB.y; } else if (posB.y > posA.y){ sum = posB.y - posA.y; } else{ return false; } if (sum!=yPositionOfSecondElement) { comply= false; } else{ comply=true; } return comply; } And here is what happens on the update: if(shouldMoveImageA && shouldMoveImageB) { if (isEligibleToMove) { [self moveBackgroundSprites:loopedBackgroundImageInstanceA :loopedBackgroundImageInstanceB :delta]; } Forget about shouldMoveImageA and shouldMoveImageB, this is just for when the background reaches the end of level, this works.

  • Why does filter: blur(0) still cause text to blur under Webkit?

    - by johnkavanagh
    I've come across a bug today that's taken far longer than I would like to admit to identify. Essentially: setting a filter: blur(0) (or the vendor-specific -webkit-filter) on an element should - I believe - mean that no form of blur is applied. However, having tested this today, it would appear that Webkit based browsers still blur the text within any element with either blur(0) or blur(0px) assigned to it. I've knocked together a quick Fiddle here: http://jsfiddle.net/f9rBE/ These are three identical dixs containing text (no custom fonts): This has absolutely nothing assigned Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aliquam facilisis orci in quam venenatis, in tempus ipsum sagittis. Suspendisse potenti. Donec ullamcorper lacus vel odio accumsan, vel aliquam libero tempor. Praesent nec libero venenatis, ultrices arcu non, luctus quam. Morbi scelerisque sit amet turpis sit amet tincidunt. Praesent semper erat non purus pretium consequat. Aenean et iaculis turpis. Curabitur diam tellus, consectetur non massa et, commodo venenatis metus. One has no styles at all assigned, the other two have blur(0) and blur(0px): .no-blur{} .zero-px-blur{ -webkit-filter: blur(0px); -moz-filter: blur(0px); -o-filter: blur(0px); -ms-filter: blur(0px); filter: blur(0px); } .zero-blur{ -webkit-filter: blur(0); -moz-filter: blur(0); -o-filter: blur(0); -ms-filter: blur(0); filter: blur(0); } If you preview this under Chrome/Safari you'll see that the text in the second two are still blurred: A few things worth noting: This unintentional blurring occurs in Safari on iOS7 devices (both iPhones and iPads); It also occurs on Chrome and Safari under OSX; It doesn't happen under FireFox in OSX. Of course, this isn't supported at all in Firefox just yet so it's hard to tell whether the behaviour I'm seeing is intentional/expected behaviour, or whether this is a bug in Webkit? Is it possible that this is only prevalent in higher-density resolution devices (ie: retina MacBook/iPhone/iPad)? With this in mind, how do you actually overwrite an item that has blur applied to it to set it back to non-blurred?

  • 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.

  • Introducing… SharePress!

    - by Bil Simser
    For those that follow me I’ve been away from blogging and twittering for a couple of months. This is the reason. For the last few months I’ve been working with a cross-functional team putting together a new product from the people that run WordPress, the free premiere blogging platform. The result is a new product we call SharePress, a highly extensible blogging and content management platform with the usability of WordPress and the power of SharePoint combined into a single product. SharePress gives you SharePoint sites that are SEO-friendly delivered with a Web 2.0 ease of use, leveraging all of the existing abilities of SharePoint and WordPress that we know today. The Reason Back in December I was approached by the WordPress team about building a new platform that took advantage of the power of SharePoint but the ease of WordPress. I’m no stranger to WordPress and it’s 5 minute no-holds-barred install (I’ve always wanted SharePoint to do this!) and I run my personal blog on WordPress as does my better half, Princess Jenn. There’s always been a pitch by so-called Web 2.0 applications to deliver the power of SharePoint but the ease of [insert product here] over the past year or so. I checked each and every one of them out, but they fell woefully short when it came to SharePoint’s document management, versioning, and customization. They try, but it’s never been up to par in my books. On the flipside, SharePoint has always been tops in collaboration in the Enterprise but it’s painful to develop web parts, UI customization can be tricky, and there’s just no user community for something as simple as themes and designs. The Product Enter SharePress. Is it SharePoint? Is it WordPress? It’s both, and neither. Everything you like about both products are there but this is a bold new product that is positioned to bring SharePoint to the masses while maintaining the fidelity of an Enterprise 2.0 collaboration platform. SharePress delivers on all fronts including: The ability to leverage any WordPress/Joomla/Drupal/DotNetNuke themes and skins inside of SharePoint Run any WordPress/Drupal/Joomla/DotNetNuke/SharePoint plug-in/module/web part/feature works out of the box with SharePress SEO-friendly URLs and pages Permalinks for all content All the features of SharePoint Server 2010 (including InfoPath, Excel, and Access services) included in the price Small deployment footprint. You decide how much to deploy and where. Independent Database Abstraction Layer (iDal) that allows you to deploy to SQL Server 2005/2008, MySQL, and PostgreSQL Portable Rendering Engine Layer (PREL) so you host .NET or PHP on Apache or IIS (version 7 or higher). The install feature is built around WordPress and it’s famous 5-minute install (actually, it’s never taken me more than 1 minute). SharePress installs with two screens after the files are uploaded to your server (which can be done entirely using FTP): After you enter two fields of information click “Install SharePress” and you’ll be done: No mess, no fuss, no complicated dependencies, and no server access required! How simpler could this be? The Technology WordPress plug-ins and themes working with SharePoint? Of course! The answer is IronPython which has now reached a maturity level capable of doing on the fly code language conversions. SharePress is a brand new product not built on top of any previous platform but leverages all the power of each of those applications through a patent pending technique called SharePress Multi-plAtfoRm Technology (SMART). SMART will convert PHP code on the fly into Python (using SWIG as an intermediate processor) which is then compiled to MSIL and then delivered back as an ASP.NET MVC application (output is C# or VB.NET, but you can build your own SMART converter to output a different language). Sound complicated? It is, but it’s all behind the scenes and you don’t have to worry about a thing. This image illustrates the technology stack and process: So users can load up out of the box PHP themes and plug-ins from the WordPress/Joomla/Drupal community into the SMART converter and output MSIL that is used by the SharePress engine and rendered on the fly to the end user. Supported PHP versions are 4.xx and 5.xx with version 6 support to come when it’s released. Similarly you can take any .NET application, DotNetNuke Module, SharePoint Web Part or event handler and feed it into the converter to output the same. Everything is reverse compiled into MSIL so it becomes technology agnostic. No source code access is needed and the SMART converter can handle obfuscated .NET assemblies that were built with .NET 1.0, 1.1, 2.0, 3.5, and 4.0. With this technology you can also with the flip of a switch have the output create PHP pages for you. This allows you to run SharePress on Unix based systems running PHP and MySQL, allowing you to deliver your SharePoint like experience to your users with a $0 infrastructure footprint. Here’s SharePress with the default WordPress post imported then a stock SharePoint collaboration site was imported. The site was then applied with the default Kubrick theme from WordPress. The Features Deploy any of the freely available 100,000 WordPress/Joomla/Drupal themes instantly to your runtime SharePress environment and preview or activate them right from your browser. Built-in Web 2.0 jQuery Enabled End User and Administrator Web Interface. Never have to remote into a server again! Run any SharePoint Web Part or Event Handler directly without modification or access to source code in SharePress. Use any WordPress/Joomla/Drupal plug-in directly in SharePress, no local admin or access to server. Just upload and activate. Upload and Activate any SharePoint Solution Package to any site remotely. No rebuilding. Changes made to sites require no compiling or rebuilding and are published immediately. Password Protected Content. You can give passwords to individual posts, articles, pages, documents, forms, and list items. A powerful polymorphic Captcha system backs the security interface and vendors can easily tie into smart card readers, fingerprint readers, and retina scanners for authorization and identification. OpenID, Windows Live, and Windows Authentication are supported out of the box. Infinitely customizable and extensible. You can leverage plug-ins from the open source community to do practically anything, all configured and uploaded via the browser. Additionally the developer API (available soon) allows you to build extensions in .NET, PHP, and Python with little effort. Easy Importing. We have importers for Blogger, WordPress, Drupal, Joomla, DotNetNuke, and SharePoint so you can populate your site quickly and easily with full metadata modeling and creation. Banner Management. It’s easy to setup banners for your web site complete with impression numbers, special URLs, and more. Menu Manager. The Menu Manager allows you to create as many menus as you want, each one can be associated to specific audiences or roles and then be styled across multiple contexts including the same menu delivered as a fly out, rollover, drop down, and just about any navigation you can think of. Collaborative ShareBook. Our exclusive book feature allows you to setup a “book” and then authorize individuals to contribute content. Permalinks. All content in SharePress has a permanent or “perma link” associated with it so people can link to it freely without fear of broken links. Apache or IIS, Unix / Linux / BSD / Solaris / Windows / Mac OS X support. Deliver SharePress the way *you* want from the platform *you* decide. Database Independence. We know people wanted to run on any database platform so SharePress is built on top of a database abstraction layer that allows you to run on SQL Server, MySQL, PostgreSQL. Other databases can be supported by writing a supporting database script consisting of fourteen function calls. The script can be written in Perl, Python, AWK, PowerShell, Unix Shell scripts, VBA, or simple DOS batch files. The Team SharePress is the work of a lot of people in both the WordPress and SharePoint community. I worked with a lot of SharePoint MVPs to create this new product as we really wanted to deliver the most compatible and feature rich system in a product that we would be proud of. Many thanks go out to Eli Bleeker, Todd Robillard, Scot Larson, Daniel Hillier, Shane Fox, Box Peran, Amanda English, and Bill Murray for doing the heavy lifting and all of their expertise and innovative thinking to get this product out. Licensing and Pricing SharePress is still in the final stages for pricing but we’re looking at a price point somewhere between $99-$100 to make it affordable for everyone. We plan to announce final pricing sometime in the next few weeks. There are no additional charges for Enterprise versions or additional features. Everything you see is what’s available and it’s just a matter of lighting up your site with whatever feature you want to enable. The product will not be open source but source code licenses will be available to ISVs who are interested in interfacing with the API at a low level. Cost will be $25,000 USD per developer and gives you complete access to the source code to the SharePress Foundation System and the .NET 4.0 Framework source code. Conclusion We hope you enjoy the launch of SharePress as the new premium blogging and content management platform for both Intranets and the Internet. We think we’ve build the best of breed solutions here and made it easy for anyone to get started with a minimal of infrastructure but allow the scalability of SharePress to shine through in the Enterprise 2.0 world. We encourage your feedback so please leave comments as to what you’re looking for in this system as we’re always evolving it to make it a better product for everyone.

  • Solaris: What comes next?

    - by alanc
    As you probably know by now, a few months ago, we released Solaris 11 after years of development. That of course means we now need to figure out what comes next - if Solaris 11 is “The First Cloud OS”, then what do we need to make future releases of Solaris be, to be modern and competitive when they're released? So we've been having planning and brainstorming meetings, and I've captured some notes here from just one of those we held a couple weeks ago with a number of the Silicon Valley based engineers. Now before someone sees an idea here and calls their product rep wanting to know what's up, please be warned what follows are rough ideas, and as I'll discuss later, none of them have any committment, schedule, working code, or even plan for integration in any possible future product at this time. (Please don't make me force you to read the full Oracle future product disclaimer here, you should know it by heart already from the front of every Oracle product slide deck.) To start with, we did some background research, looking at ideas from other Oracle groups, and competitive OS'es. We examined what was hot in the technology arena and where the interesting startups were heading. We then looked at Solaris to see where we could apply those ideas. Making Network Admins into Socially Networking Admins We all know an admin who has grumbled about being the only one stuck late at work to fix a problem on the server, or having to work the weekend alone to do scheduled maintenance. But admins are humans (at least most are), and crave companionship and community with their fellow humans. And even when they're alone in the server room, they're never far from a network connection, allowing access to the wide world of wonders on the Internet. Our solution here is not building a new social network - there's enough of those already, and Oracle even has its own Oracle Mix social network already. What we proposed is integrating Solaris features to help engage our system admins with these social networks, building community and bringing them recognition in the workplace, using achievement recognition systems as found in many popular gaming platforms. For instance, if you had a Facebook account, and a group of admin friends there, you could register it with our Social Network Utility For Facebook, and then your friends might see: Alan earned the achievement Critically Patched (April 2012) for patching all his servers. Matt is only at 50% - encourage him to complete this achievement today! To avoid any undue risk of advertising who has unpatched servers that are easier targets for hackers to break into, this information would be tightly protected via Facebook's world-renowned privacy settings to avoid it falling into the wrong hands. A related form of gamification we considered was replacing simple certfications with role-playing-game-style Experience Levels. Instead of just knowing an admin passed a test establishing a given level of competency, these would provide recruiters with a more detailed level of how much real-world experience an admin has. Achievements such as the one above would feed into it, but larger numbers of experience points would be gained by tougher or more critical tasks - such as recovering a down system, or migrating a service to a new platform. (As long as it was an Oracle platform of course - migrating to an HP or IBM platform would cause the admin to lose points with us.) Unfortunately, we couldn't figure out a good way to prevent (if you will) “gaming” the system. For instance, a disgruntled admin might decide to start ignoring warnings from FMA that a part is beginning to fail or skip preventative maintenance, in the hopes that they'd cause a catastrophic failure to earn more points for bolstering their resume as they look for a job elsewhere, and not worrying about the effect on your business of a mission critical server going down. More Z's for ZFS Our suggested new feature for ZFS was inspired by the worlds most successful Z-startup of all time: Zynga. Using the Social Network Utility For Facebook described above, we'd tie it in with ZFS monitoring to help you out when you find yourself in a jam needing more disk space than you have, and can't wait a month to get a purchase order through channels to buy more. Instead with the click of a button you could post to your group: Alan can't find any space in his server farm! Can you help? Friends could loan you some space on their connected servers for a few weeks, knowing that you'd return the favor when needed. ZFS would create a new filesystem for your use on their system, and securely share it with your system using Kerberized NFS. If none of your friends have space, then you could buy temporary use space in small increments at affordable rates right there in Facebook, using your Facebook credits, and then file an expense report later, after the urgent need has passed. Universal Single Sign On One thing all the engineers agreed on was that we still had far too many "Single" sign ons to deal with in our daily work. On the web, every web site used to have its own password database, forcing us to hope we could remember what login name was still available on each site when we signed up, and which unique password we came up with to avoid having to disclose our other passwords to a new site. In recent years, the web services world has finally been reducing the number of logins we have to manage, with many services allowing you to login using your identity from Google, Twitter or Facebook. So we proposed following their lead, introducing PAM modules for web services - no more would you have to type in whatever login name IT assigned and try to remember the password you chose the last time password aging forced you to change it - you'd simply choose which web service you wanted to authenticate against, and would login to your Solaris account upon reciept of a cookie from their identity service. Pinning notes to the cloud We also all noted that we all have our own pile of notes we keep in our daily work - in text files in our home directory, in notebooks we carry around, on white boards in offices and common areas, on sticky notes on our monitors, or on scraps of paper pinned to our bulletin boards. The contents of the notes vary, some are things just for us, some are useful for our groups, some we would share with the world. For instance, when our group moved to a new building a couple years ago, we had a white board in the hallway listing all the NIS & DNS servers, subnets, and other network configuration information we needed to set up our Solaris machines after the move. Similarly, as Solaris 11 was finishing and we were all learning the new network configuration commands, we shared notes in wikis and e-mails with our fellow engineers. Users may also remember one of the popular features of Sun's old BigAdmin site was a section for sharing scripts and tips such as these. Meanwhile, the online "pin board" at Pinterest is taking the web by storm. So we thought, why not mash those up to solve this problem? We proposed a new BigAddPin site where users could “pin” notes, command snippets, configuration information, and so on. For instance, once they had worked out the ideal Automated Installation manifest for their app server, they could pin it up to share with the rest of their group, or choose to make it public as an example for the world. Localized data, such as our group's notes on the servers for our subnet, could be shared only to users connecting from that subnet. And notes that they didn't want others to see at all could be marked private, such as the list of phone numbers to call for late night pizza delivery to the machine room, the birthdays and anniversaries they can never remember but would be sleeping on the couch if they forgot, or the list of automatically generated completely random, impossible to remember root passwords to all their servers. For greater integration with Solaris, we'd put support right into the command shells — redirect output to a pinned note, set your path to include pinned notes as scripts you can run, or bring up your recent shell history and pin a set of commands to save for the next time you need to remember how to do that operation. Location service for Solaris servers A longer term plan would involve convincing the hardware design groups to put GPS locators with wireless transmitters in future server designs. This would help both admins and service personnel trying to find servers in todays massive data centers, and could feed into location presence apps to help show potential customers that while they may not see many Solaris machines on the desktop any more, they are all around. For instance, while walking down Wall Street it might show “There are over 2000 Solaris computers in this block.” [Note: this proposal was made before the recent media coverage of a location service aggregrator app with less noble intentions, and in hindsight, we failed to consider what happens when such data similarly falls into the wrong hands. We certainly wouldn't want our app to be misinterpreted as “There are over $20 million dollars of SPARC servers in this building, waiting for you to steal them.” so it's probably best it was rejected.] Harnessing the power of the GPU for Security Most modern OS'es make use of the widespread availability of high powered GPU hardware in today's computers, with desktop environments requiring 3-D graphics acceleration, whether in Ubuntu Unity, GNOME Shell on Fedora, or Aero Glass on Windows, but we haven't yet made Solaris fully take advantage of this, beyond our basic offering of Compiz on the desktop. Meanwhile, more businesses are interested in increasing security by using biometric authentication, but must also comply with laws in many countries preventing discrimination against employees with physical limations such as missing eyes or fingers, not to mention the lost productivity when employees can't login due to tinted contacts throwing off a retina scan or a paper cut changing their fingerprint appearance until it heals. Fortunately, the two groups considering these problems put their heads together and found a common solution, using 3D technology to enable authentication using the one body part all users are guaranteed to have - pam_phrenology.so, a new PAM module that uses an array USB attached web cams (or just one if the user is willing to spin their chair during login) to take pictures of the users head from all angles, create a 3D model and compare it to the one in the authentication database. While Mythbusters has shown how easy it can be to fool common fingerprint scanners, we have not yet seen any evidence that people can impersonate the shape of another user's cranium, no matter how long they spend beating their head against the wall to reshape it. This could possibly be extended to group users, using modern versions of some of the older phrenological studies, such as giving all users with long grey beards access to the System Architect role, or automatically placing users with pointy spikes in their hair into an easy use mode. Unfortunately, there are still some unsolved technical challenges we haven't figured out how to overcome. Currently, a visit to the hair salon causes your existing authentication to expire, and some users have found that shaving their heads is the only way to avoid bad hair days becoming bad login days. Reaction to these ideas After gathering all our notes on these ideas from the engineering brainstorming meeting, we took them in to present to our management. Unfortunately, most of their reaction cannot be printed here, and they chose not to accept any of these ideas as they were, but they did have some feedback for us to consider as they sent us back to the drawing board. They strongly suggested our ideas would be better presented if we weren't trying to decipher ink blotches that had been smeared by the condensation when we put our pint glasses on the napkins we were taking notes on, and to that end let us know they would not be approving any more engineering offsites in Irish themed pubs on the Friday of a Saint Patrick's Day weekend. (Hopefully they mean that situation specifically and aren't going to deny the funding for travel to this year's X.Org Developer's Conference just because it happens to be in Bavaria and ending on the Friday of the weekend Oktoberfest starts.) They recommended our research techniques could be improved over just sitting around reading blogs and checking our Facebook, Twitter, and Pinterest accounts, such as considering input from alternate viewpoints on topics such as gamification. They also mentioned that Oracle hadn't fully adopted some of Sun's common practices and we might have to try harder to get those to be accepted now that we are one unified company. So as I said at the beginning, don't pester your sales rep just yet for any of these, since they didn't get approved, but if you have better ideas, pass them on and maybe they'll get into our next batch of planning.
