• Execution plan warnings–All that glitters is not gold

  - by Dave Ballantyne

  In a previous post, I showed you the new execution plan warnings related to implicit and explicit warnings.  Pretty much as soon as i hit ’post’,  I noticed something rather odd happening. This statement : select top(10) SalesOrderHeader.SalesOrderID, SalesOrderNumberfrom Sales.SalesOrderHeaderjoin Sales.SalesOrderDetail on SalesOrderHeader.SalesOrderID = SalesOrderDetail.SalesOrderID   Throws the “Type conversion may affect cardinality estimation” warning.     Ive done no such conversion in my statement why would that be ?  Well, SalesOrderNumber is a computed column , “(isnull(N'SO'+CONVERT([nvarchar](23),[SalesOrderID],0),N'*** ERROR ***'))”,  so thats where the conversion is.   Wait!!! Am i saying that every type conversion will throw the warning ?  Thankfully, no.  It only appears for columns that are used in predicates ,even if the predicate / join condition is fine ,  and the column is indexed ( and/or , presumably has statistics).    Hopefully , this wont lead to to many wild goose chases, but is definitely something to bear in mind.  If you want to see this fixed then upvote my connect item here.

• preseeded installation keeps asking for confirmation while creating RAID-Partitions on certain hardware-platform

  - by Marc Shennon

  I am aware of the partman-md/confirm_nooverwrite thing, that was the solution to most of this problems in the past. The thing is, that the preseed-file works for almost all hardware-platforms I tested, but only for one (Primergy MX130) it keeps asking for confirmation, before writing the partition-layout to the disks. All machines I tested are running with two SATA Disks, nothing special. I'm not really sure, what information could be needed in order to investigate the cause of this behaviour, but I would of course be willing to provide more information, if someone has an idea. Relevant part of the preseed file is the following: d-i partman-auto/disk string /dev/sda /dev/sdb d-i partman-auto/method string raid d-i partman-md/confirm boolean true d-i partman-partitioning/confirm_write_new_label boolean true d-i partman-md/device_remove_md boolean true d-i partman/choose_partition select finish d-i partman-md/confirm_nooverwrite boolean true # Write the changes to disks? d-i partman/confirm boolean true d-i mdadm/boot_degraded boolean true # RECIPE # Next you need to specify the physical partitions that will be used. d-i partman-auto/expert_recipe string \ multiraid :: \ 500 10000 1000000000 raid $lvmignore{ }\ $primary{ } \ method{ raid } \ . \ 512 1000 786 raid $lvmignore{ }\ $primary{ } \ method{ raid } \ . \ 8192 10240 10240 raid $lvmignore{ }\ method{ raid } \ . # Parameters are: # <raidtype> <devcount> <sparecount> <fstype> <mountpoint> <devices> <sparedevices> d-i partman-auto-raid/recipe string \ 1 2 0 ext4 / /dev/sda1#/dev/sdb1 . \ 1 2 0 ext2 /boot /dev/sda2#/dev/sdb2 . \ 1 2 0 swap - /dev/sda5#/dev/sdb5 .

• Looking for way to download all the free software I need to setup my PC all at once . . .

  - by Jim McKeeth

  I am in the middle of reinstalling Windows 7, and I would like to install all the software in as few steps as possible. I saw a web site recently that listed a lot of different Freeware and Opensource appliations. There was a checkmark next to each one so you could select the ones you want, and then they would all download in a single package to install at one time. The idea was for when you were setting up after a fresh install. It was for Windows and they were adding 64-bit applications.

• How to make a text search template?

  - by Flipper

  I am not really sure what to call this, but I am looking for a way to have a "template" for my code to go by when searching for text. I am working on a project where a summary for a piece of text is supplied to the user. I want to allow the user to select a piece of text on the page so that the next time they come across a similar page I can find the text. For instance, lets say somebody goes to foxnews.com and selects the article like in the image below. Then whenever they go to any other foxnews.com article I would be able to identify the text for the article and summarize it for them. But an issue I see with this is for a site like Stack Exchange where you have multiple comments to be selected (like below) which means that I would have to be able to recursively search for all separate pieces of text. Requirements Be able to keep pieces of text separate from each other. Possible Issues DIV's may not contain ids, classes, or names. A piece of text may span across multiple DIVs How to recognize where an old piece of text ends and a new begins. How to store this information for later searching?

• Why does my downloads folder take so long to load?

  - by msbg

  When I open my downloads folder, no files appear, just a message saying "This folder is empty". I see the address bar progress slowly creeping along, and after about thirty seconds the files and folders appear. This problem only occurs in the downloads folder. If I search for a file in the downloads folder, it comes up, and if I right click on it and select "Open File Location", everything shows up instantly. I am using Windows 8, but I think I had a similar problem once in Windows 7. Sadly I can't remember how I fixed it.

• web based source control management software [closed]

  - by tom smith

  hi. not sure if this is the right place, but hopefully someone might have thoughts on a solution/vendor. Starting to spec out a project that will require multiple (50-100) developers to be able to manipulate source files/scripts for a large scale project. The idea is to be able to have each app go through a dev/review/test process, where the users can select (or be assigned) the role they're going to have for the given app. I'm looking for web-based, version control, issue tracking, user roles/access, workflow functionality, etc... Ideally, the process will also allow for the reviewed/valid app to then be exported to a separate system for testing on the test server/environment. This can be hosted on our servers, or we can do the colo process. I've checked out Alassian/Collabnet, but any thoughts you can provide would me appreciated as well. thanks

• Convert uploaded video files to mp4 using PHP [closed]

• Architecture : am I doing things right?

  - by Jeremy D

  I'm trying to use a '~classic' layered arch using .NET and Entity Framework. We are starting from a legacy database which is a little bit crappy: Inconsistent naming Unneeded views (view referencing other views, select * views etc...) Aggregated columns Potatoes and Carrots in the same table etc... So I ended with fully isolating my database structure from my domain model. To do so EF entities are hidden from presentation layer. The goal is to permit an easier database refactoring while lowering the impact of it on applications. I'm now facing a lot of challenges and I'm starting to ask myself if I'm doing things right. My Domain Model is highly volatile, it keeps evolving with apps as new fields needs are arising. Complexity of it keeps raising and class it contains start to get a lot of properties. Creating include strategy and reprojecting to EF is very tricky (my domain objects don't have any kind of lazy/eager loading relationship properties): DomainInclude<Domain.Model.Bar>.Include("Customers").Include("Customers.Friends") // To... IFooContext.Bars.Include(...).Include(...).Where(...) Some framework are raping the isolation levels (Devexpress Grids which needs either XPO or IQueryable for filtering and paging large data sets) I'm starting to ask myself if : the isolation of EF auto-generated entities is an unneeded cost. I should allow frameworks to hit IQueryable? Slow slope to hell? (it's really hard to isolate DevExpress framework, any successful experience?) the high volatility of my domain model is normal? Did you have similar difficulties? Any advice based on experience?

• Can't start firewall or automatic updates in Windows XP

  - by Chris Porter

  On a friends laptop following some viruses infestations there is a problem in starting the Windows firewall. The error is: Could not start the Windows Firewall/Internet Connection Sharing(ICS) service on Local Computer. Error 2: The system cannot find the file specified When attempting to turn on automatic updates in the security centre, the message is: We're sorry. The Security Center could not change your Automatic Updates settings. To try changing these settings yourself, go to System in Control Panel. On the Automtic Updates tab, select Automatic (recommended), and then click OK. All the options under "Automatic Updates" are greyed out. I've tried the suggestions below and many others: http://windowsxp.mvps.org/sharedaccess.htm http://support.Microsoft.com/kb/892199 http://windowsxp.mvps.org/repairwmi.htm I can't do a repair install because the installer doesn't detect existing versions. It's XP pro service pack 3.

• Microsoft Outlook 2007 - General Failure. The URL was: "<http:/something.com>". The parameter is incorrect

  - by Simon Peverett

  For the last two days, Outlook has decided it doesn't like URL's. Any email message that comes in containing an URL will show the following in an error dialogue message box when I click on the link: General Failure. The URL was: "http:/something.com/somewhere/". The parameter is incorrect If I copy the link into a browser, it works correctly. OS is Windows XP SP 3, Microsoft Office 2007 (Outlook), Internet Explorer 8 (also Chrome). I have, of course, Googled this and the two most popular solutions are: Solution 1: Add/Remove programs Set Program Access and Defaults Custom tab Make sure a default browser is selected Solution 2: Add/Remove Programs Select the MS Office 2007 item Click Change Click Repair I have tried both of these and I still get the problem. Has anyone else had this problem and solved it with a solution other than those listed above?

• Have Windows Automatically Login Without Entering Your Password

  - by deadlydog

  If you are like me and don't want to have to enter your password each time Windows loads, you can have Windows start up without prompting you to enter a user name or password.  The simple (and BAD) way to do this is to simply not have a password on your user account, but that’s a big security risk and will allow people to easily remote desktop into your computer. So, first set a password on your windows account if you don’t already have one.  Then select Run... from the start menu (or use Windows Key + R to open the Run window) and type control userpasswords2, which will open the user accounts application.   On the Users tab, clear the box for Users must enter a user name and password to use this computer, and click on OK. An Automatically Log On dialog box will appear; enter the user name and password for the account you want to use to automatically log into Windows.  That's it.    You may also want to make sure your screen saver is not set to prompt you for a password when it exits either. Now your computer is secure without getting in your way.

• Project Server 2010 site creation - the database connection string is not available

  - by Brandon Montgomery

  I am trying to get Project Server 2010 up and running on a Win Server 2008 box. I've got Sharepoint 2010 installed and Project Server 2010 installed. I open SharePoint Central Administration, then I go to Manage Service Applications Project Server Service Application. It looks like there is a site under the "Sharepoint - 80" section, but the Status says "Failed - see the Application event Log". When I click on the site and select "Retry" I get the same thing. In the event viewer, I see an error with SharePoint Foundation Search as the Source - it reads: Could not create a database session. Context: Application '276504a6-93b1-4c1f-a900-fd6ed9d5c117' Details: The database connection string is not available. (0xc0041228) How can I fix this? Is there some configuration I missed?

• More than one way to skin an Audit

  - by BuckWoody

  I get asked quite a bit about auditing in SQL Server. By "audit", people mean everything from tracking logins to finding out exactly who ran a particular SELECT statement. In the really early versions of SQL Server, we didn't have a great story for very granular audits, so lots of workarounds were suggested. As time progressed, more and more audit capabilities were added to the product, and in typical database platform fashion, as we added a feature we didn't often take the others away. So now, instead of not having an option to audit actions by users, you might face the opposite problem - too many ways to audit! You can read more about the options you have for tracking users here: http://msdn.microsoft.com/en-us/library/cc280526(v=SQL.100).aspx  In SQL Server 2008, we introduced SQL Server Audit, which uses Extended Events to really get a simple way to implement high-level or granular auditing. You can read more about that here: http://msdn.microsoft.com/en-us/library/dd392015.aspx  As with any feature, you should understand what your needs are first. Auditing isn't "free" in the performance sense, so you need to make sure you're only auditing what you need to. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• Windows 7- New Windows Are Not Displayed

  - by Peter

  I am running an up-to-date and OEM version of Windows 7. I have been experiencing an annoying problem for the past few weeks where new windows are not displayed 70-80% of the time. For example, when I launch notepad, the notepad window is not displayed or when I select save from the file menu, the save dialog is not displayed. The window is there, but it is not being displayed; the screen is not refreshed. The way to work around this problem is to force a system-wide refresh by pressing CTRL+SHIFT+DEL and then cancelling hiding all windows using "show desktop" then displaying the window needed via taskbar Can anyone please point me in the right direction to solving this problem? What could be causing this?

• How to best config my PC. 2 small SDDs and a 1TB conventional drive

  - by Chadworthington

  I just got a new PC. It has 3 drives C Drive: 80GB SDD Drive P Drive: 120GB SDD (for core programs) D Drive: 1TB SDD (for data and other) I have an MSDN subscription and I am the type of person that loves to install tons of software to check it out. I am very worried that installation programs are forcing me to place a large amount of files on the small C drive. I fear that I will quickly run out of space on my C drive while having ample space on my TB drive. What would you do in my shoes? I didn't select this PC or set the config up. I am wishing that the 120 SSD was my C, to give me a little more room to grow. I guess there are no magic solutions here but I am just looking for your general thoughts

• Monitor resolution messed up somehow

  - by Kelp

  I purchased the Westinghouse 22" LCD LCM-22w3 a few years ago, and now it's been acting up on me. I just booted into Windows 7(without changing any settings), and the default resolution is 1600x1024, and it allows me to select a refresh rate of up to 85 Hz(it didn't let me do that). I usually have my resolution set to 1680x1050 with a refresh rate of 60 Hz. Now, that resolution does not even appear in the list. Does anyone have any idea of what could be the problem and how to fix it? Edit: I am not sure if this will help, but when I go to change the screen resolution, the monitor is known as "Generic Non-PnP Monitor". It used to be referred to as "Generic PnP Monitor). I tried to disable Generic Non-PnP Monitor, but when I restart, it uses that monitor again. Edit 2: I created a custom .inf file using Powerstrip, but that does not work either. The monitor settings are being stubborn.

• Impact Earth Lets You Simulate Asteroid Impacts

  - by Jason Fitzpatrick

  If you’re looking for a little morbid simulation to cap off your Friday afternoon, this interactive asteroid impact simulator makes it easy to the results of asteroid impacts big and small. The simulator is the result of a collaboration between Purdue University and the Imperial College of London. You can adjust the size, density, impact angle, and impact velocity of the asteroid as well as change the target from water to land. The only feature missing is the ability to select a specific location as the point of impact (if you want to know what a direct strike to Paris would yield, for example, you’ll have to do your own layering). Once you plug all that information in, you’re treated to a little 3D animation as the simulator crunches the numbers. After it finishes you’ll see a breakdown of a variety of effects including the size of the crater, the energy of the impact, seismic effects, and more. Hit up the link below to take it for a spin.

• Rules Manager and Expression Filter getting removed

  - by Mike Dietrich

  I doubt that many people are using the Oracle features "Rules Manager" and "Expression Filter" as usually people handle these things (such as ensuring that a zip code or a car number plate has a certain format) within the application code and not inside the database. Oracle Beehive for instance uses that just on the side.  Anyway, just learned today that Rules Manager and Expression Filter components will get removed once our next database release most likely called Oracle Database 12c will get released. So before upgrading to Oracle Database 12c you can remove EXF and RUL components (SELECT COMP_ID FROM DBA_REGISTRY WHERE COMP_ID IN ('EXF','RUL'); ). You'd simply do that by executing the following script before upgrade:SQL> @?/rdbms/admin/catnoexf.sqlThis will clean up Rules Manager and Expression Filter components inside the database. You could run ?/rdbms/admin/catnorul.sql before but I believe catnoexf.sql will clean up everything already. And you'll find all this information plus guidelines for migration of existing content in MOS Note: 1233535.1 - Obsolescence Notice: Rules Manager and Expression Filter Features of Oracle Database -M.

• Apple Mail Rules application

  - by Steve

  I've got a Mac running Apple Mail and a bberry, both checking the same mail accounts. One account is pop and two accounts are IMAP. The Mac is asleep during the day. While out and about, I'll check my mail on the bberry, read the new messages, and leave them in my inbox. When I come home, I wake up the Mac, and Mail syncs with the server. The filtering rules are not applied to messages that are previously read via bberry. Can I apply rules to 'read' messages? I've tried to select emails in the inbox and then apply rules to them, but that doesn't move the message.

• Context Menu for Browser to download file to specific folder

  - by elcojon

  There is this website which has customized audio files for me. I would like to save them in a special folder. Now I don't want to select the "special folder" each time in the file-chooser dialogue of my browser. I would rather prefer to have a custom entry in the context menu when I right-click the download link. This context-menu-entry should do the trick and download the file to the predefined "special folder". How would I start about that? I am using Safari and Chrome. So a solution in either browser is fine. To get into the context menu of the browser, what kind of programming do I need to do? Is it an extension, plugin, etc.? Thanks

• Windows 8.1 - unfixable grub

  - by Nick

  I have a Gigabyte laptop that came with secure boot and windows 8. After a bit of battling, I managed to get my dual boot with Ubuntu 13.10.. Anyway, I upgraded zindows to 8.1, now grub is gone. I restarted from a live CD and chrooted to my drive. I used boot-repair multiple times (with successful output) both in default and with some advanced options; also reinstalled grub manually... Each time it tries once to boot to grub but gives a message for a very short amount of time. I recorded it and it is a regular bios message "Rebbot and Select proper Boot device of Insert Boot media in selected boot device and press a key" I even tried something called EasyBCD under winblows, it shows the correct boot options, but same there, it is unable to make the linux partition fire up. Anyway, no way to boot my linux box. Does anyone have an idea how to fix this? No need to redirect me to another post with grub reinstall or boot-repair, seen them all... I am thinking of trying this other boot loader, refind, to see if it works http://www.rodsbooks.com/refind/index.html Also re-reading this bios message, I'm thinking my partition might not have a boot flag anymore... I'll try that too with parted. Although both grub and win 8 are supposed to fire up from the same boot partition (the EFI one) Please help! thx
