  • How to auto-unlock Keyring Manager in 12.10?

    - by Torben Gundtofte-Bruun
    How can I auto-unlock the Keyring Manager in 12.10? This answer for 11.10 doesn't seem to apply because the Keyring Manager looks different in 12.10 so I can't follow the instructions. I have set up my machine to automatically log in to my account. I don't mind the lesser security of having the keyring automatically unlocked. (This is still a home desktop computer of a simple user, not a missile launch system.)

    I pasted syslog and perhaps anyone can see trouble that might need attention. It is running too slow for what I would suspect.

  • After update UBUNTU 12.04 changes wired interface from eth0 to eth1, network configuration fails

    - by Don McLaren
    I have been running UBUNTU 12.04 for a couple of months on this system with no problems. After a recent update, the bootup fails to define the wired network interface as eth0, so the default network configuration fails. ifconfig -a shows eth1 instead, as unconfigured. Booting from CD works OK, configures eth0 as normal. Solution: sudo NetworkManager The network manager figures out the situation, and configures eth1 Question: Where did this problem come from all of a sudden?

  • But what version is the database now?

    - by BuckWoody
    When you upgrade your system to SQL Server 2008 R2, you’ll know that the instance is at that version by using the standard commands like SELECT @@VERSION or EXEC xp_msver. My system came back with this info when I typed those: Microsoft SQL Server 2008 R2 (RTM) - 10.50.1600.1 (Intel X86)   Apr  2 2010 15:53:02   Copyright (c) Microsoft Corporation  Developer Edition on Windows NT 6.0 <X86> (Build 6002: Service Pack 2) (Hypervisor) Index Name Internal_Value Character_Value 1 ProductName NULL Microsoft SQL Server 2 ProductVersion 655410 10.50.1600.1 3 Language 1033 English (United States) 4 Platform NULL NT INTEL X86 5 Comments NULL SQL 6 CompanyName NULL Microsoft Corporation 7 FileDescription NULL SQL Server Windows NT 8 FileVersion NULL 2009.0100.1600.01 ((KJ_RTM).100402-1540 ) 9 InternalName NULL SQLSERVR 10 LegalCopyright NULL Microsoft Corp. All rights reserved. 11 LegalTrademarks NULL Microsoft SQL Server is a registered trademark of Microsoft Corporation. 12 OriginalFilename NULL SQLSERVR.EXE 13 PrivateBuild NULL NULL 14 SpecialBuild 104857601 NULL 15 WindowsVersion 393347078 6.0 (6002) 16 ProcessorCount 1 1 17 ProcessorActiveMask 1 1 18 ProcessorType 586 PROCESSOR_INTEL_PENTIUM 19 PhysicalMemory 2047 2047 (2146934784) 20 Product ID NULL NULL   But a database properties are separate from the Instance. After an upgrade, you always want to make sure that the compatibility options (which have much to do with how NULLs and other objects are treated) is at what you expect. For the most part, as long as the application can handle it, I set my compatibility levels to the latest version. For SQL Server 2008, that was “10.0” or “10”. You can do this with the ALTER DATABASE command or you can just right-click the database and select “Properties” and then “Database Options” in SQL Server Management Studio. To check the database compatibility level, I use this query: SELECT name, cmptlevel FROM sys.sysdatabases When I did that this morning I saw that the databases (all of them) were at 10.0 – not 10.5 like the Instance. That’s expected – we didn’t revise the database format up with the Instance for this particular release. Didn’t want to catch you by surprise on that. While your databases should be at the “proper” level for your situation, you can’t rely on the compatibility level to indicate the Instance level. More info on the ALTER DATABASE command in SQL Server 2008 R2 is here: http://technet.microsoft.com/en-us/library/bb510680(SQL.105).aspx Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • How to record streaming camera video and auto-erase old data before drive fills up?

I want to get network cameras similar to this: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=260745150596 I want a way to dump or record the live stream to a large hard drive, but have Ubuntu automatically delete the oldest parts of the video while the drive fills, so it can continue recording new data continuously. How can this auto-delete while recording be accomplished? I've searched and searched.

  • Portable class libraries and fetching JSON

    - by Jeff
    After much delay, we finally have the Windows Phone 8 SDK to go along with the Windows 8 Store SDK, or whatever ridiculous name they’re giving it these days. (Seriously… that no one could come up with a suitable replacement for “metro” is disappointing in an otherwise exciting set of product launches.) One of the neat-o things is the potential for code reuse, particularly across Windows 8 and Windows Phone 8 apps. This is accomplished in part with portable class libraries, which allow you to share code between different types of projects. With some other techniques and quasi-hacks, you can share some amount of code, and I saw it mentioned in one of the Build videos that they’re seeing as much as 70% code reuse. Not bad. However, I’ve already hit a super annoying snag. It appears that the HttpClient class, with its idiot-proof async goodness, is not included in the Windows Phone 8 class libraries. Shock, gasp, horror, disappointment, etc. The delay in releasing it already caused dismay among developers, and I’m sure this won’t help. So I started refactoring some code I already had for a Windows 8 Store app (ugh) to accommodate the use of HttpWebRequest instead. I haven’t tried it in a Windows Phone 8 project beyond compiling, but it appears to work. I used this StackOverflow answer as a starting point since it’s been a long time since I used HttpWebRequest, and keep in mind that it has no exception handling. It needs refinement. The goal here is to new up the client, and call a method that returns some deserialized JSON objects from the Intertubes. Adding facilities for headers or cookies is probably a good next step. You need to use NuGet for a Json.NET reference. So here’s the start: using System.Net; using System.Threading.Tasks; using Newtonsoft.Json; using System.IO; namespace MahProject {     public class ServiceClient<T> where T : class     {         public ServiceClient(string url)         {             _url = url;         }         private readonly string _url;         public async Task<T> GetResult()         {             var response = await MakeAsyncRequest(_url);             var result = JsonConvert.DeserializeObject<T>(response);             return result;         }         public static Task<string> MakeAsyncRequest(string url)         {             var request = (HttpWebRequest)WebRequest.Create(url);             request.ContentType = "application/json";             Task<WebResponse> task = Task.Factory.FromAsync(                 request.BeginGetResponse,                 asyncResult => request.EndGetResponse(asyncResult),                 null);             return task.ContinueWith(t => ReadStreamFromResponse(t.Result));         }         private static string ReadStreamFromResponse(WebResponse response)         {             using (var responseStream = response.GetResponseStream())                 using (var reader = new StreamReader(responseStream))                 {                     var content = reader.ReadToEnd();                     return content;                 }         }     } } Calling it in some kind of repository class may look like this, if you wanted to return an array of Park objects (Park model class omitted because it doesn’t matter): public class ParkRepo {     public async Task<Park[]> GetAllParks()     {         var client = new ServiceClient<Park[]>(http://superfoo/endpoint);         return await client.GetResult();     } } And then from inside your WP8 or W8S app (see what I did there?), when you load state or do some kind of UI event handler (making sure the method uses the async keyword): var parkRepo = new ParkRepo(); var results = await parkRepo.GetAllParks(); // bind results to some UI or observable collection or something Hopefully this saves you a little time.

  • Can not authenticate to run GParted

    - by alfish
    Whenever I try to run a program from gnome gui, I get message Authenticated is required to run the Gparted Partition Editor The same goes for all programs that need root permission and I try to run from 'System tools' in my gnome-fallback. However the same user can become root in gnome terminal with no problem (I added the user to sudoers). I must mention that I've changed the user's password after OS install, so I think I need to update something but don't know what. I appreciate your hints.
