  • Caching strategies - LRU, MRU, Clock-Pro

    - by golgofa
    I am going to write a bachelor's science work on caching strategies and really, can't find any links to specifications or full descriptions of some of them. Only something like summaries from wikipedia. Please, help with some links on LRU, MRU caching and new-one - Clock Pro. Thanks a lot. All links are very useful for me. The purpose of work - is to compare different cache strategies to get more effiency. It based on WebApplication with ejb 2.0, so algorithm's will be implemented there, espesially in ejbLoad() and ejbFindByPrimarKey(). Also, one of aspects of this application - it will use not common scheme of tables in database - it based on metamodel. So, if you had any experience on this topic, i would be grateful to take some of your knowledge)

  • How To See Who Logged Into a Computer and When

    - by Chris Hoffman
    Have you ever wanted to monitor who’s logging into your computer and when? On Professional editions of Windows, you can enable logon auditing to have Windows track which user accounts log in and when. The Audit logon events setting tracks both local logins and network logins. Each logon event specifies the user account that logged on and the time the login took place. You can also see when users logged off. How to Get Pro Features in Windows Home Versions with Third Party Tools HTG Explains: Is ReadyBoost Worth Using?

  • If my URL's are static, but then parsed by Javascript, does that make it crawlable?

    - by Talasan Nicholson
    Lets say I have a link: <a href="/about/">About Us</a> But in Javascript [or jQuery] catches it and then adds the hash based off of the href attribute: $('a').click(function(e) { e.preventDefault(); // Extremely oversimplified.. window.location.hash = $(this).attr('href'); }); And then we use a hashchange event to do the general 'magic' of Ajax requests. This allows for the actual href to be seen by crawlers, but gives client-side users with JS enabled an ajax-based website. Does this 'help' the general SEO issues that come along with hashtags? I know hashbangs are 'ok', but afaik they aren't reliable?

  • Accessing managers from game entities/components

    - by Boreal
    I'm designing an entity-component engine in C# right now, and all components need to have access to the global event manager, which sends off inter-entity events (every entity also has a local event manager). I'd like to be able to simply call functions like this: GlobalEventManager.Publish("Foo", new EventData()); GlobalEventManager.Subscribe("Bar", OnBarEvent); without having to do this: class HealthComponent { private EventManager globalEventManager; public HealthComponent(EventManager gEM) { globalEventManager = gEM; } } // later on... EventManager globalEventManager = new EventManager(); Entity playerEntity = new Entity(); playerEntity.AddComponent(new HealthComponent(globalEventManager)); How can I accomplish this? EDIT: I solved it by creating a singleton called GlobalEventManager. It derives from the local EventManager class and I use it like this: GlobalEventManager.Instance.Publish("Foo", new EventData());

  • Colour scheme for editor - guidelines or medical reccomendations

    - by Kevin D
    Is anyone aware of any studies on what colour scheme is best for use in multi-coloured text based computer work? Specifically in terms of reducing eye strain. For instance is a black back ground and light text best? Should it be a dark colour rather than going all the way to black? I've seen the questions on this site about "which is your favourite" that is not what I am after. I also aware that my question may be to specific asking for a colour scheme, if anyone could link me to some guidelines instead that would be appreciated as well. I'm concious of the fact that anyone using a computer is really using it for text based work but with the multitude of colours used to convey information within our modern IDEs I feel this is a good StackExchange site for this question.

  • How can I render player movement on a 2d plane efficiently?

    - by user422318
    I'm prototyping a 2d HTML5 game with similar interaction to Diablo II. (See an older post of mine describing the interaction here: How can I imitate interaction and movement in Diablo II?) I just got the player click-to-move system working using the Bresenham algorithm but I can't figure out how to efficiently render the player's avatar as he moves across the screen. By the time redraw() is called, the player has already finished moving to the target point. If I try to call redraw() more frequently (based on my game timer), there's incredible system lag and I don't even see the avatar image glide across the screen. I have a game timer based off this awesome timer class: http://www.dailycoding.com/Posts/object_oriented_programming_with_javascript__timer_class.aspx In the future, there will be multiple enemies chasing the player. Fast pace is essential to the experience. What should I do?

  • Recommended 2D Game Engine for prototyping

    - by Thomas Dufour
    What high-level game engine would you recommend to develop a 2D game prototype on windows? (or mac/linux if you wish) The kind of things I mean by "high-level" includes (but is definitely not limited to): not having to manage low-level stuff like screen buffers, graphics contexts having an API to draw geometric shapes well, I was going to omit it but I guess being based on an actual "high-level" language is a plus (automatic resource management and the existence a reasonable set of data structures in the standard library come to mind). It seems to me that Flash is the proverbial elephant in the room for this query but I'd very much like to see different answers based on all kinds of languages or SDKs.

  • BeanInfo Editor in NetBeans Rocks

    - by Geertjan
    Impressed by a cool feature I didn't know about. If you have some JavaBean, like my Event class below, you can right-click it and choose "BeanInfo Editor": Now, as you can see above, I don't have a BeanInfo class. So I am now asked whether the IDE should create one for me. So I say OK and then I have a new BeanInfo class, generated from my Event class, as well as a multiview editor for visually editing the BeanInfo class: Thanks Eric and Nicklas from Artificial Solutions in Stockholm for pointing this out to me today. It comes in very handy in NetBeans Platform applications when you're working with a BeanNode and want to customize the display of your properties.

  • Should I leave href empty when implementing click events via jQuery?

    - by dreza
    Is it preferable to have # in a link's href attribute when I am implementing the click event via jQuery, or is it ok to leave href empty? i.e. <a id="myLink" href="#" /> vs <a id="myLink" href="" /> When I'm doing $("#myLink").on('click', function() { // do ajaxy stuff }); Although I understand the click event could be on a span or other such element I'm interested in this case for particular best practices when using an a tag.

  • AGPL License - does it apply in this scenario?

    - by user1645310
    There is an AGPLv3 based software (Client) that makes web service calls (using SOAP) to another software (Server - commercial, cloud based). There is no common code or any connection whatsoever between these two except for the web service calls being made. My questions - Does the Server need to be AGPL too? I guess not - but would like to confirm. Let us say the end point URL for the Server can be configured on the Client side (by editing an XML file) to connect it to different Servers (again, there is no connection other than the webservice calls being made) does it require any of these Servers being AGPL? Are there any issues in running the Client as a DLL that is loaded by other commercial applications on users' desktops? Does it require these other applications also to be AGPL?

  • On-Premises to Office 365: Identity

    - by Sahil Malik
    SharePoint, WCF and Azure Trainings: more information “Run your business, not your mail server.” I am not sure where I read that, but it makes so much sense! Every organization is moving to the cloud, and some just haven’t started their journey yet. One of the fastest and most compelling online cloud based offerings is Office 365. Available in various SKUs, you can get SharePoint, Lync, Exchange, and Office professional as cloud-based offerings. The subscriptions are as low as $2 per user per month to $20 something per user per month. Also, with SharePoint 2013, if you buy Office 365 subscriptions for your users, you don’t need to buy CALs (Client Access Licenses) for on-premises use. Read full article here.

  • Are there any additional considerations to make when designing a site structure if you plan to use persistent connection technologies?

    - by Psytronic
    As the title states, I'm thinking of making a simple-card-game based website, using persistent connection technology (Something like signalR) for the actual game part of it. I've never planned a site to use this technology, and wondering for those who have, are there any additional things that need to be taken into consideration for the site structure? I'm planning on using the asp MVC framework for the whole thing, and starting off with some simple game (e.g. card based Rock/Paper/Scissors) for proof of concept (to see if I can get it working how I think it would in my head).

  • Meet Windows Azure Sweden &amp; SWAG Sommeravslutning

    - by Alan Smith
    The Meet Windows Azure event last week saw some great announcements about the current and future developments on the Windows Azure platform. Microsoft Sweden will be hosting an event at their offices that will run through these releases and demo some of the new technologies. It will be a great chance to see the new capabilities in action, and chat to Microsoft Evangelists, MVPs and other developers about the future of the platform. This will also be the last Sweden Windows Azure Group (SWAG) meeting before the summer break, so there will be food, drinks, and the chance of some “SWAG”. We will be back in force after the summer, and have a number of great events planned for the rest of the year. We will have a big announcement to make regarding one of these, so be there and get the chance to register! Registration is here.
