  • Why make JavaScript class based?

    - by Carnotaurus
    JavaScript is a prototype language. To turn it into a class based language adds little value? I am not talking about best-practice here. I remember reading an article from way back, which claimed that the class-based worldview is perceivably more flawed than the one of prototypes. My summary can be found here: http://carnotaurus.tumblr.com/post/3248631891/class-based-javascript-or-not. I am resisting to use the class-based jQuery add-on and other attempts at faciliating class-based JavaScript. Peer pressure is strong but is there a stronger theoretical or practical reason why I stop resisting?

  • Token based Authentication and Claims for Restful Services

    - by Your DisplayName here!
    WIF as it exists today is optimized for web applications (passive/WS-Federation) and SOAP based services (active/WS-Trust). While there is limited support for WCF WebServiceHost based services (for standard credential types like Windows and Basic), there is no ready to use plumbing for RESTful services that do authentication based on tokens. This is not an oversight from the WIF team, but the REST services security world is currently rapidly changing – and that’s by design. There are a number of intermediate solutions, emerging protocols and token types, as well as some already deprecated ones. So it didn’t make sense to bake that into the core feature set of WIF. But after all, the F in WIF stands for Foundation. So just like the WIF APIs integrate tokens and claims into other hosts, this is also (easily) possible with RESTful services. Here’s how. HTTP Services and Authentication Unlike SOAP services, in the REST world there is no (over) specified security framework like WS-Security. Instead standard HTTP means are used to transmit credentials and SSL is used to secure the transport and data in transit. For most cases the HTTP Authorize header is used to transmit the security token (this can be as simple as a username/password up to issued tokens of some sort). The Authorize header consists of the actual credential (consider this opaque from a transport perspective) as well as a scheme. The scheme is some string that gives the service a hint what type of credential was used (e.g. Basic for basic authentication credentials). HTTP also includes a way to advertise the right credential type back to the client, for this the WWW-Authenticate response header is used. So for token based authentication, the service would simply need to read the incoming Authorization header, extract the token, parse and validate it. After the token has been validated, you also typically want some sort of client identity representation based on the incoming token. This is regardless of how technology-wise the actual service was built. In ASP.NET (MVC) you could use an HttpModule or an ActionFilter. In (todays) WCF, you would use the ServiceAuthorizationManager infrastructure. The nice thing about using WCF’ native extensibility points is that you get self-hosting for free. This is where WIF comes into play. WIF has ready to use infrastructure built-in that just need to be plugged into the corresponding hosting environment: Representation of identity based on claims. This is a very natural way of translating a security token (and again I mean this in the widest sense – could be also a username/password) into something our applications can work with. Infrastructure to convert tokens into claims (called security token handler) Claims transformation Claims-based authorization So much for the theory. In the next post I will show you how to implement that for WCF – including full source code and samples. (Wanna learn more about federation, WIF, claims, tokens etc.? Click here.)

  • Do I need to create my own or use a commercial server for the features and matchmaking options I want my game to support?

    - by baptzmoffire
    So I'm developing an indie turn-based game for iOS and, in coding up a Game Center matchmaking class, I'm starting to question whether Game Center is even the best choice for what I want this game to do. I need to figure out whether I need to create my own server, invest in a preexisting client or server service, or if I even need to use a server at all. If I do need to use a ready-made service other than Game Center, which server would accomodate my game's needs best? I have limited resources and funds. Here is the list of features I want my game to support, ideally: Turn-based gameplay (a la "with Friends" and "with Buddies" games) Smart matchmaking (matching users up with other players of comparable skill/achievements) Random matchmaking Facebook matchmaking Specific username matchmaking Contact list matchmaking A way to select what "type" of match you want to challenge an opponent to. (In random, smart, and Facebook matchmaking, there will be different "wagers" the player can make. [e.g. "I wanna play a random opponent for 1000 points. Now, I wanna play my Facebook buddy for 1,000,000 points."] There will be a predetermined range of amounts you can play for. It won't be customizable.) Buddies list capability (Game-buddies, as opposed to contacts and Facebook) A higher concurrent game cap than Game Center offers (which I still can't really find a straight answer on) Scalability (it should support 2 or 20,000,000 players) Objective-C compatibility Flexibility (for all the stuff I haven't thought of yet) Am I dreaming, here? Is there even a service that can handle all of these features? Do I need to invest months in learning a networking language to build my own? If so, how much would I need to spend on hardware? I've been looking around all morning and, so far, the only seemingly viable option is SmartFox. Under "Everything and the kitchen sink" section here, it says they support "virtual world with Zones, Rooms and RoomGroups, create complex game challenges, send invitations, manage buddy lists, create custom permission profiles, oversee the security aspects and tons more." http://www.smartfoxserver.com/overview/platform Is there an option that Im just overlooking? Thanks for any help anyone can provide. Sorry for the long poast. One last question: Does anyone know which server Dice with Buddies uses? I was experimenting with how many concurrent games I could get going and my ADHD kicked in at about 80 games. 80 concurrent games would be great for my game, but again, I need the other features I mentioned too. Thanks again.

  • Tactics for using PHP in a high-load site

    - by Ross
    Before you answer this I have never developed anything popular enough to attain high server loads. Treat me as (sigh) an alien that has just landed on the planet, albeit one that knows PHP and a few optimisation techniques. I'm developing a tool in PHP that could attain quite a lot of users, if it works out right. However while I'm fully capable of developing the program I'm pretty much clueless when it comes to making something that can deal with huge traffic. So here's a few questions on it (feel free to turn this question into a resource thread as well). Databases At the moment I plan to use the MySQLi features in PHP5. However how should I setup the databases in relation to users and content? Do I actually need multiple databases? At the moment everything's jumbled into one database - although I've been considering spreading user data to one, actual content to another and finally core site content (template masters etc.) to another. My reasoning behind this is that sending queries to different databases will ease up the load on them as one database = 3 load sources. Also would this still be effective if they were all on the same server? Caching I have a template system that is used to build the pages and swap out variables. Master templates are stored in the database and each time a template is called it's cached copy (a html document) is called. At the moment I have two types of variable in these templates - a static var and a dynamic var. Static vars are usually things like page names, the name of the site - things that don't change often; dynamic vars are things that change on each page load. My question on this: Say I have comments on different articles. Which is a better solution: store the simple comment template and render comments (from a DB call) each time the page is loaded or store a cached copy of the comments page as a html page - each time a comment is added/edited/deleted the page is recached. Finally Does anyone have any tips/pointers for running a high load site on PHP. I'm pretty sure it's a workable language to use - Facebook and Yahoo! give it great precedence - but are there any experiences I should watch out for? Thanks, Ross

  • Turn off all sounds from websites

    - by David Oneill
    Often, I am listening to music of my choosing. Is there a way to preemptively turn off all sounds originating from websites? I don't want to click the 'mute' button once the page loads. And sometimes, it won't even have a mute. :-/ I use Chromium and FireFox. ~~EDIT~~ I use XFCE, so my menu options are different. Is this a gnome-specific utility? Or, what is the command for this utility?

  • Turn off laptop display and have monitor

    - by Ryan B
    My laptop display has stopped working and is unfixable! Anyway, I got a full HD monitor and plugged that into the HDMI port of the laptop. I have changed the power settings so that I can close the lid and still have the monitor on, and this all works. However because it is on "mirror displays", I cannot get the full 1080p resolution that the monitor supports, and when I turn off mirror displays and switch off the laptop screen, the monitor will also switch off! I'm really stuck, as I can only get the monitor to display its full resolution if I have it with the laptop screen turned on, and I dont want this because (as the laptop display does not work) things get lost on that side of the screen. HELP. (Dell Studio 1537 Monitor is Samsung SA300 Connected through HDMI Ubuntu 11.10)

  • After suspend, my monitor wont turn back on

    - by David
    I set my pc to suspend after 5 minutes of inactivity, when I return to my computer I mash a couple of keys and the pc turns back on and the drives start spinning etc etc, but I get no signal to either of my monitors. My peripherals are powered as the num/caps lock lights turn on and off. I should add I have two monitors, I have the same problem on both. As I am writing the last line from my previous paragraph keeps disappearing. I press control z and it comes back but kinda weird. Thanks in advance for any help :)

  • Ubuntu 12.10 "Turn screen off when inactive for: Never" still turns off

    - by Will
    After a fresh install of Ubuntu 12.10, my screen still goes off after about ten minutes. I've been to the Brightness and Lock control panel. The Turn screen off when inactive for: setting is set for Never. I've been through the dconf Editor searching for power, screen, and idle changing parameters. This doesn't seem to have any effect on the display timeout. Here's one more interesting thing, the screen doesn't go off, per se. It just goes black. Meaning, the back lighting is still on, and all the pixels are black. When it goes black, it does a very pleasant quick dim to black. Similarly, it quickly un-dim's after a key press, mouse movement, or mouse click. So, I'm feeling this is more of a software setting the timeout, not a power saving function.

  • How to completely turn off session saving?

    - by Thorn
    Hi all, I opened System > Preferences > Startup Application > Options and clicked on Remember currently running Applications. I suppose this makes Ubuntu memorize (save a list on some place in disk) all currently running applications and when you reboot your computer, the OS starts with everything in that list. Now I want to get rid of it. Of course I can close all applications which I do not want to start in startup, and click Remember currently running Applications again, but this doesn't seem to work as expected. For example, Yakuake opens differently if I do that. What I want is to completely turn off session saving. Maybe I can delete the stored information somehow?

  • Turn Off Sleep on Seagate GoFlex?

    - by RPG Master
    I bought this 2tb Segate GoFlex this last Black Friday and since then every 15 minutes or so the drive spins down, and then a little while later completely dismounts. Very annoying. From what I understand you could turn this off using the including Windows and Mac only software. This function and what controls it isn't proprietary, right? There has to be something that'll let me set it in Ubuntu... Anyone have any suggestions? Also, I formatted it to EXT4. Hope I didn't screw myself up. :/

  • Antec Fusion Black LCD won't turn off on system shutdown

    - by Niklas
    Hi! I've been struggling a while with getting the iMON LCD/IR-receiver on my Antec Fusion Black case to shutdown together with the system (XBMC Live 10 - ubuntu based). But it won't. When it's turned off the LCD still lights up the whole room. Many have proposed the "solution" of setting the machine into hibernation instead but that however won't work for me, since I'm unable to suspend my system. It is the LCD/IR-module that prevents me from suspending and I haven't found a solution to properly unload it on suspending (it's way above my linux knowledge). I need help with getting the display to turn off the backlight when the system is turned off. Can anyone please help me? If anyone also has the knowledge on how to get the eject function to work on my Antec Veris rm200 remote I would be very grateful, I was told about that it could get fixed with irexec but I do not know how since I haven't been able to find a good tutorial on the subject. Thank you for helping me!

  • How to turn on/off code modules?

    - by Safran Ali
    I am trying to run multiple sites using single code base and code base consist of the following module (i.e. classes) User module Q & A module Faq module and each class works on MVC pattern i.e. it consist of Entity class Helper class (i.e. static class) View (i.e. pages and controls) and let's say I have 2 sites site1.com and site2.com. And I am trying to achieve following functionality site1.com can have User, Q & A and Faq module up and running site2.com can have User and Q & A module live while Faq module is switched off but it can be turned-on if needed, so my query here is what is the best way to achieve such functionality Do I introduce a flag bit that I check on every page and control belonging to that module? It's more like CMS where you can turn on/off different features. I am trying to get my head around it, please provide me with an example or point out if I am taking the wrong approach.

  • I want to turn VB.Net Option Strict On

    - by asjohnson
    I recently found out about strong typing in VB.Net (naturally it was on here, thanks!) and am deciding I should take another step toward being a better programmer. I went from vba macros - VB.Net, because I needed a program that I could automate and I never read anything about strong typing, so I kind of fell into the VB.Net default trap. Now I am looking to turn it on and sort out this whole type thing. I was hoping someone could direct me towards some resources to make this transistion as painless as possible. I have read around some and ctype seems to come up a lot, but past that I am at a bit of a loss. What are the benefits of switching? Is there more to it than just using ctype to cast things? I feel like there is a good article that I have failed to come across and any direction would be great. Would a good approach to be to rewrite a program that is written with option strict off and note differences?

  • Screen doesn't turn back on after resume on a Lenovo Thinkpad T420

    - by Wojtek
    Every time I suspend my notebook (Lenovo Thinkpad T420 - Intel HD graphic card) on Oneiric Ocelot 11.10 and turn it back on, the screen is black. The backlight is on and the system itself loads fine, but the display somehow doesn't get back. The first time after a fresh reboot the screen isn't black, it is mostly white/light-gray and it looks a bit like a distorted image. The pixels fade in until it gets almost completely light-gray. I've got a workaround for this: I switch to the first terminal (CTRL+ALT+F1) and back to X (CTRL+ALT+F7). In most cases that helps. Sometimes, when there's still a problem, I log in on the first terminal and run "unity --reset". Then go back to X - this helps always. I can tell that the system comes back, because I can log in with my fingerprint reader (or wait a bit and put in the password) "blindly", then do the workaround - I am logged in after the screen comes back. So it's only the display that is not working. Any help or advice where to look would be appreciated.

  • Turn O&M Operations into Optimized Projects with Oracle Primavera

    - by mark.kromer
    Oracle enterprise project portfolio management with Primavera is much more than optimizing project performance and eliminating project failure on new projects, capital programs, etc. A very common use case that we see is small-scale frequent and recurring projects based on on-going operations and maintenance. As opposed to assigning resources to various activities when you are building a new network infrastructure, for example, Oracle has teamed-up the Primavera and eBusiness Suite teams to provide direct integration for work orders from Oracle's Enterprise Asset Management (eAM) system to populate into Primavera P6 project schedules. So now that your network infrastructure build-out project is complete, planners and operations managers can use the world-class what-if and scheduling capabilities in Primavera tools to assign work orders, maximize resource utilization and to reuse templates for typical O&M operations in Primavera and share that back to the operations teams using eAM for maintenance. Also, large-scale maintenance operations related to large assets in the asset lifecycle will include phase-outs, shutdowns and turn-arounds which are classic maintenance projects, as opposed to building something new, that Oracle Primavera with Oracle e-Business Suite provides full coverage to optimize your ALM processes in your business. Read more about these new capabilities from Oracle in the ERP space from the Oracle eAM data sheet.

  • Turn Your Browser Pane into a Game of Katamari Damacy

    - by Jason Fitzpatrick
    If you’re a fan of Katamari Damacy, a quirky and fun Japanese puzzle game made popular on the PlayStation, you’ll love this Javas script hack that turns your browser pane and its contents into a giant HTML-collecting game of Katamari Damacy. Katamari Damacy, for the unfamiliar, is a addictive game based on the premise that a galactic prince is on a mission to rebuild stars, constellations, and moons accidentally destroyed by his father. You roll around and collect objects (making yourself an increasingly larger ball in the process). This script hack puts a ball on your web browser pane (works best in Chrome) that you can roll around collecting elements from the web page. At first you can only grab links but as you grow you can grab increasingly large objects like photo elements off the page. It doesn’t have the sophisticated graphics of the Playstation version, of course, nor the detailed back story, but it’s a clever little hack that is sure to delight fans of Katamari Damacy.

  • How one decision can turn web services to hell

    - by DigiMortal
    In this posting I will show you how one stupid decision may turn developers life to hell. There is a project where bunch of complex applications exchange data frequently and it is very hard to change something without additional expenses. Well, one analyst thought that string is silver bullet of web services. Read what happened. Bad bad mistake In the early stages of integration project there was analyst who also established architecture and technical design for web services. There was one very bad mistake this analyst made: All data must be converted to strings before exchange! Yes, that’s correct, this was the requirement. All integers, decimals and dates are coming in and going out as strings. There was also explanation for this requirement: This way we can avoid data type conversion errors! Well, this guy works somewhere else already and I hope he works in some burger restaurant – far away from computers. Consequences If you first look at this requirement it may seem like little annoying piece of crap you can easily survive. But let’s see the real consequences one stupid decision can cause: hell load of data conversions are done by receiving applications and SSIS packages, SSIS packages are not error prone and they depend heavily on strings they get from different services, there are more than one format per type that is used in different services, for larger amounts of data all these conversion tasks slow down the work of integration packages, practically all developers have been in hurry with some SSIS import tasks and some fields that are not used in different calculations in SSAS cube are imported without data conversions (by example, some prices are strings in format “1.021 $”). The most painful problem for developers is the part of data conversions because they don’t expect that there is such a stupid requirement stated and therefore they are not able to estimate the time their tasks take on these web services. Also developers must be prepared for cases when suddenly some service sends data that is not in acceptable format and they must solve the problems ASAP. This puts unexpected load on developers and they are not very happy with it because they can’t understand why they have to live with this horror if it is possible to fix. What to do if you see something like this? Well, explain the problem to customer and demand special tasks to project schedule to get this mess solved before going on with new developments. It is cheaper to solve the problems now that later.
