  • Scuttlebutt Reconciliation from "Efficient Reconciliation and Flow Control for Anti-Entropy Protocols"

    - by Maus
    This question might be more suited to math.stackexchange.com, but here goes: Their Version Reconciliation takes two parts-- first the exchange of digests, and then an exchange of updates. I'll first paraphrase the paper's description of each step. To exchange digests, two peers send one another a set of pairs-- (peer, max_version) for each peer in the network, and then each one responds with a set of deltas. The deltas look like: (peer, key, value, version), for all tuples for which peer's state maps the key to the given value and version, and the version number is greater than the maximum version number peer has seen. This seems to require that each node remember the state of each other node, and the highest version number and ID each node has seen. Question Why must we iterate through all peers to exchange information between p and q?

  • kubuntu: wireless manager can't find any networks

    - by timuçin
    I just installed Kubuntu 12.10 and as I knew my wireless driver would not be recognized, I installed it manually through here. I suppose I shall mention that I also had to do this. The driver worked just fine until I restarted my system. Since then I can't even start over. My wireless card is realtek 8723 The oly lead I have is this piece of log: 11/14/12 07:35:21 AM timucin-W150ER NetworkManager[989] <info> wpa_supplicant started 11/14/12 07:35:21 AM timucin-W150ER NetworkManager[989] <info> (wlan0) supports 4 scan SSIDs 11/14/12 07:35:21 AM timucin-W150ER NetworkManager[989] <info> (wlan0): supplicant interface state: starting -> ready 11/14/12 07:35:21 AM timucin-W150ER NetworkManager[989] <info> (wlan0): device state change: unavailable -> disconnected (reason 'supplicant-available') [20 30 42] 11/14/12 07:35:21 AM timucin-W150ER NetworkManager[989] <warn> Trying to remove a non-existant call id. 11/14/12 07:35:21 AM timucin-W150ER NetworkManager[989] <info> (wlan0): supplicant interface state: ready -> inactive 11/14/12 07:35:21 AM timucin-W150ER NetworkManager[989] <info> (wlan0) supports 4 scan SSIDs I feel really bad that I have been trying so many things and even while I am trying them I get a problem at every step. I am really frustrated. You can the time in the logs, I didn't get up early. Just needed to share my feelings. Even the ethernet cable I have use is short for God's sake, I have had to sit at this massively uncomfortable posture for hours. edit: I discovered something interesting. When I boot my windows I see that my wireless manager says "disconnected" now. However when I start ubuntu after windows and modprobe rtl8723e wireless works just fine. Then again, when I restart ubuntu I am back where I have started. So now I have to start windows, restart my machine and do the modprobe thing to see wireless networks.

  • ASP.NET MVC Portable Areas - Can they communicate and be used as a plugin-like architecture?

    - by Beton
    I'll get straight to the point: I was wondering if there is a common pattern to use portable areas as a components of a plugin-like architecture. Example: We've got 3 plugins (portable areas) packaged and distributed via NuGet feed. Each of them is following the standard MVC structure (has it own Models, Views and Controllers). Lets say login form, header and footer. What I was wondering if there is a way to make them communicate. For example: when user logs on, login plugin executes it own logic, logs the user and then it updates the state of the header plugin with changes it state accordingly. Thanks in advance.

  • XNA When to call LoadContent

    - by Peteyslatts
    I have an enum in my game that denotes the game state ie MainMenu, InGame, GameOver, Exit and I was wondering if it would be advisable to add a new one in for PrepGame - in which the game creates viewports for however many players there are, creates the battlefield etc. I feel like this is a good idea except for one thing: should I make a call back to LoadContent() in this state? I could just put a switch statement in the LoadContent for my currentGameState. If it equals PrepGame load things like the skybox, ship models, texures, HUD graphics etc. Or is it a good idea to create an Asset Manager class in the first call to LoadContent() and load everything then. I feel like both approaches have different benefits: faster, but more load times vs slower initial load time, but then all my objects are referencing the same variables so I only have to load each on once. Any help is greatly appreciated. Thanks, Peter

Basically i'm getting lots of spam from particular state and there are some webmaster copying my content without any attribution or backlink.

Do you have any suggestions for php scripts that help block particular geolocation ? and another question: if there are any SEO disadvantages ?

  • Is software support an option for your career?

    - by Maria Sandu
    Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 If you have a technical background, why should you choose a career in support? We have invited Serban to answer these questions and to give us an overview of one of the biggest technical teams in Oracle Romania. He’s been with Oracle for 7 years leading the local PeopleSoft Financials & Supply Chain Support team. Back in 2013 Serban started building a new support team in Romania – Fusion HCM. His current focus is building a strong support team for Fusion HCM, latest solution for Business HR Professionals from Oracle. The solution is offered both on Premise (customer site installation) but more important as a Cloud offering – SaaS.  So, why should a technical person choose Software Support over other technical areas?  “I think it is mainly because of the high level of technical skills required to provide the best technical solutions to our customers. Oracle Software Support covers complex solutions going from Database or Middleware to a vast area of business applications (basically covering any needs that a large enterprise may have). Working with such software requires very strong skills both technical and functional for the different areas, going from Finance, Supply Chain Management, Manufacturing, Sales to other very specific business processes. Our customers are large enterprises that already have a support layer inside their organization and therefore the Oracle Technical Support Engineers are working with highly specialized staff (DBA’s, System/Application Admins, Implementation Consultants). This is a very important aspect for our engineers because they need to be highly skilled to match our customer’s specialist’s expectations”.  What’s the career path in your team? “Technical Analysts joining our teams have a clear growth path. The main focus is to become a master of the product they will support. I think one need 1 or 2 years to reach a good level of understanding the product and delivering optimal solutions because of the complexity of our products. At a later stage, engineers can choose their professional development areas based on the business needs and preferences and then further grow towards as technical expert or a management role. We have analysts that have more than 15 years of technical expertise and they still learn and grow in technical area. Important fact is, due to the expansion of the Romanian Software support center, there are various management opportunities. So, if you want to leverage your experience and if you want to have people management responsibilities Oracle Software Support is the place to be!”  Our last question to Serban was about the benefits of being part of Oracle Software Support. Here is what he said: “We believe that Oracle delivers “State of the art” Support level to our customers. This is not possible without high investment in our staff. We commit from the start to support any technical analyst that joins us (being junior or very senior) with any training needs they have for their job. We have various technical trainings as well as soft-skills trainings required for a customer facing professional to be successful in his role. Last but not least, we’re aiming to make Oracle Romania SW Support a global center of excellence which means we’re investing a lot in our employees.”  If you’re looking for a job where you can combine your strong technical skills with customer interaction Oracle Software Support is the place to be!

  • What is a good university for computer science and game development?

    - by DukeYore
    I am starting my computer science degree at a local community college in programming using C++. However, I will be transferring to a 4-year university. Does anyone have any insight on university programs? I know Cal State Fullerton has a degree with a minor in Game Development. however, is that as important as getting a degree from a really great school? If I could shoot for something like Cal Poly would that be better? Or even Stanford or SF State being so close to so many gaming companies up there in the Bay area?

  • Processing a list of atomic operations, allowing for interruptions

    - by JDB
    I'm looking for a design pattern that addresses the following situation: There exists a list of tasks that must be processed. Tasks may be added at any time. Each task is wholly independent from all other tasks. The order in which tasks are processed has no effect on the overall system or on the tasks themselves. Every task must be processed once and only once. The "main" process which launches the task processors may start and stop without warning. When stopped, the "main" process loses all in-memory data. Obviously this is going to involve some state, but are there any design patterns which discuss where and how to maintain that state? Are there any relevant anti-patterns? Named patterns are especially helpful so that we can discuss this topic with other organizations without having to describe the entire problem domain.
