  • Consolidate information held in a number of SQL Server Express Instances

    - by user321271
    Hi, I'm trying to determine the best architecture for creating an oData web service for information held in a number of SQL Server Express instances. The web service should provide a consolidated view of the data. All the SQL Server Express instances have the same DB schema. I was initially planning to use SQL server replication however as I understand it, SQL Server 2008 Express cannot be used as a publisher. Any help or suggestions would be appreciated.

  • MySQL: how to index an "OR" clause

    - by JoséMi
    I'm executing the following query SELECT COUNT(*) FROM table WHERE field1='value' AND (field2 = 1000 OR field3 = 2000) There is one index over field1 and another composited over field2&field3. I see MySQL always selects the field1 index and then makes a join using the other two fields which is quite bad because it needs to join 146.000 rows. Suggestions on how to improve this? Thanks

  • atheros wireless device driver

    - by Rolo Susie
    I got a new laptop recently, and have been having trouble with it dropping wifi since I got it, the card is Qualcomm Atheros ar9485wb-eg. I've updated to the latest available drivers, currently 10.0.0.263, and tried other suggestions on the lenovo website, including uninstalling the driver and letting it install again. One thing I've noticed is when I look at the troubleshooting log, it gives the device driver number as 10.0.0.209. Does this mean the update isn't applying properly? Any help appreciated, Thanks

  • Strongest cipher available to use with C/C++ ?

    - by George0x77
    I am just wondering if you are supposed to write a sort of really secure application with data being transmitted over insecure networks, what kind of encryption algorithm will you use it in order to make it safe ? I know several c++ libraries for encryption providing nice functions with different algorithms, but i'm not quite sure which cipher to use - AES, DES, RSA, Blowfish or maybe something more different ? Please provide your ideas and suggestions. Thank you.

  • Using mod_negotiation to serve webp if the UA requests it.

    - by Rich Bradshaw
    Is it possible to use mod_negotiation to serve up a webp image if the browser supports it, and a jpg otherwise? For instance, if I link to an image with the path /images/test, it serves the image found at /images/test.webp if the UA knows about webp, or jpg otherwise? I've tried poking around, but it seems that the Accept headers in Chrome at least look like Accept:*/*, rather than specifying the image type. If this isn't the way to do it, has anyone got any other suggestions?

  • Getting scp's status bar to appear in a Java window

    - by pete
    I'm writing a program that uses scp to copy files in a bigger java program. As it stands now, the program freezes up while the scp is copying the file, which can take a few minutes, so I'd like to be able to display the progress of the scp or at the very least get the terminal window with the scp progress to show up! Any suggestions?

  • Can an ASP.NET page be a WebService also?

    - by halivingston
    I know it's a little odd, specifically because a Page inherits from the System.Web.Page (or something) and a WebService inherits from System.Web.Service (or something). But just thought I'd ask if there is any way to do this? Does anyone have suggestions to do this?

  • Set Date in a single line

    - by hibernate
    According to the java API, the constructor Date(year, month, day) is depreciated. I know that I can replace it with the following code: Calendar myCal = Calendar.getInstance(); myCal.set(Calendar.YEAR, theYear); myCal.set(Calendar.MONTH, theMonth); myCal.set(Calendar.DAY_OF_MONTH, theDay); Date theDate = myCal.getTime(); However, I would like something shorter to replace it with (ideally one-two lines). Any suggestions?
