• How do I tar dot files but not dot directories

  - by bjackfly

  The following tar command will exclude all dot files and dot directories. tar -cvzf /media/bjackfly/bkup/bkup.gz --exclude '.*' --one-file-system /home/bjackfly In my case I want the dot files to be backed up in the home directory (.vimrc, .bashrc) etc. but not the dot directories /.config /.cache /.eclipse etc. Any Linux gurus with a command for this, or do I need to run a find into a tar or do two different tar commands which is non-ideal? One for dot files in the home directory and one for everything else?

• Impact of ordering of correlated subqueries within a projection

  - by Michael Petito

  I'm noticing something a bit unexpected with how SQL Server (SQL Server 2008 in this case) treats correlated subqueries within a select statement. My assumption was that a query plan should not be affected by the mere order in which subqueries (or columns, for that matter) are written within the projection clause of the select statement. However, this does not appear to be the case. Consider the following two queries, which are identical except for the ordering of the subqueries within the CTE: --query 1: subquery for Color is second WITH vw AS ( SELECT p.[ID], (SELECT TOP(1) [FirstName] FROM [Preference] WHERE p.ID = ID AND [FirstName] IS NOT NULL ORDER BY [LastModified] DESC) [FirstName], (SELECT TOP(1) [Color] FROM [Preference] WHERE p.ID = ID AND [Color] IS NOT NULL ORDER BY [LastModified] DESC) [Color] FROM Person p ) SELECT ID, Color, FirstName FROM vw WHERE Color = 'Gray'; --query 2: subquery for Color is first WITH vw AS ( SELECT p.[ID], (SELECT TOP(1) [Color] FROM [Preference] WHERE p.ID = ID AND [Color] IS NOT NULL ORDER BY [LastModified] DESC) [Color], (SELECT TOP(1) [FirstName] FROM [Preference] WHERE p.ID = ID AND [FirstName] IS NOT NULL ORDER BY [LastModified] DESC) [FirstName] FROM Person p ) SELECT ID, Color, FirstName FROM vw WHERE Color = 'Gray'; If you look at the two query plans, you'll see that an outer join is used for each subquery and that the order of the joins is the same as the order the subqueries are written. There is a filter applied to the result of the outer join for color, to filter out rows where the color is not 'Gray'. (It's odd to me that SQL would use an outer join for the color subquery since I have a non-null constraint on the result of the color subquery, but OK.) Most of the rows are removed by the color filter. The result is that query 2 is significantly cheaper than query 1 because fewer rows are involved with the second join. All reasons for constructing such a statement aside, is this an expected behavior? Shouldn't SQL server opt to move the filter as early as possible in the query plan, regardless of the order the subqueries are written?

• Wireless internet connection connects but internet does not work (no packets received). Wired does.

  - by Rodney

  When I connect my PC via ethernet cable to my ADSL router it works fine. When I connect via Wireless it connects and the internet will work for a random amount of time and then stop working. It stays connected with a strong signal but no packets are received. My laptop/iphone are right next to it and wireless works fine. If I open the Wireless USB status, it says it is connected to my SSID with full strength (54 mps - I am 3 meteres away from my router) and the activty shows as Packets 594 SENT and 105 RECEIVED (this goes up VERY slowly) I have tried the following: Turned off anitvirus and firewall completely. Tested the wifi signal- I am writing this on my laptop which is next to my PC and also has full wifi strength. Tried a different wireless adapter - I dug out an old PCI wireless card - it does the exact same thing. Compared all wireless settings to my laptop. I can ping google.com and it replies (sometimes with packet loss) When I reboot the PC it will connect for a minute or two (random time) and then just stops again. I tried Firefox, IE etc. no joy I have updated all latest versions (Netgear WG111v2) and drivers Checked Event Log - nothing unusual Ping the router (and even connect as admin for the few minutes when the internet does work) Changed the MTU down to 1200 using DrTCP Checked Device Manager for conflicts - none. I ping the router from the PC (192.168.0.10 - 192.168.0.1) and it replies with 4 packets. BUT, on my router admin page (which I access via http on my laptop wirelessly) - if I ping 192.168.0.10 all packets timeout (pinging my laptop 192.168.0.12 works fine) My router admin page shows the leased IP address for 192.168.0.10 (ie it is definitely talking to the router initially) Now I am out of ideas - please help. I think it is an OS/Software issue as I have tried 2 different wireless adapaters (PCI and USB) with the same result but all other wireless devices work fine around mine). It's not the firewall. It is getting assigned an IP address correctly (my PC gets 192.168.0.10, my laptop is .12) It is assigned by DHCP. As soon as I plug in the ethernet cable it all works fine. Repairing the adapter sometimes helps but it will always stop working after a random time. The wireless adapter always shows as connected with Excellent signal but the internet does not work. I am running Windows XP SP3 and have tried a Netgear WG111v2 USB adapter. Thanks in advance! UPDATE: The internet seems to be working, it is just either sending packets too small or slow to work (some small pages load bits of them very slowly but then hang). XP seems to have a networking diagnostic app - here is the output: Last diagnostic run time: 08/30/10 08:16:38 IP Configuration Diagnostic Invalid IP address info Valid IP address detected: 192.168.0.10 IP Layer Diagnostic Corrupted IP routing table info The default route is valid info The loopback route is valid info The local host route is valid info The local subnet route is valid Invalid ARP cache entries action The ARP cache has been flushed Gateway Diagnostic Gateway info The following proxy configuration is being used by IE: Automatically Detect Settings:Disabled Automatic Configuration Script: Proxy Server: Proxy Bypass list: info This computer has the following default gateway entry(ies): 192.168.0.1 info This computer has the following IP address(es): 192.168.0.10 info The default gateway is in the same subnet as this computer info The default gateway entry is a valid unicast address info The default gateway address was resolved via ARP in 1 try(ies) info The default gateway was reached via ICMP Ping in 1 try(ies) info TCP port 80 on host 65.55.12.249 was successfully reached info The Internet host www.microsoft.com was successfully reached info The default gateway is OK DNS Client Diagnostic DNS - Not a home user scenario info Using Web Proxy: no info Resolving name ok for (www.microsoft.com): yes No DNS servers DNS failure HTTP, HTTPS, FTP Diagnostic HTTP, HTTPS, FTP connectivity info FTP (Passive): Successfully connected to ftp.microsoft.com. info HTTP: Successfully connected to www.microsoft.com. warn HTTPS: Error 12002 connecting to www.microsoft.com: The operation timed out warn HTTPS: Error 12002 connecting to www.passport.net: The operation timed out error Could not make an HTTPS connection. info Redirecting user to support call WinSock Diagnostic WinSock status info All base service provider entries are present in the Winsock catalog. info The Winsock Service provider chains are valid. info Provider entry MSAFD Tcpip [TCP/IP] passed the loopback communication test. info Provider entry MSAFD Tcpip [UDP/IP] passed the loopback communication test. info Provider entry RSVP UDP Service Provider passed the loopback communication test. info Provider entry RSVP TCP Service Provider passed the loopback communication test. info Connectivity is valid for all Winsock service providers.

• Problems with WCF endpoints hosted from Windows Service

  - by Dilip

  I have a managed Windows Service that hosts a couple of WCF endpoints. The service is set to start automatically when the PC is restarted. On reboot I find that this line of code: ServiceHost wcfHost1 = new ServiceHost(typeof(WCFHost1)); in the OnStart() method of the service takes somewhere between 15 - 20 seconds to execute. Actually I have two such statements but the second one executes in a flash. It is the first one that takes so long. Does anyone know what could be causing the bottleneck? Because of this, sometimes the call exceeds 30 seconds and as a result the SCM thinks my service timed out while trying to initialize itself. Now, I know its easy for me to just spin off a thread to do this and return from OnStart() right away but I'd like to know what could cause this delay. This happens only when the service starts up on PC reboot. If the PC is up and running, the service starts & stops in less than a second.

• handling NSStream events when using EASession in MonoTouch

  - by scotru

  Does anyone have an example of how to handle read and write NSStream events in Monotouch when working with accessories via EASession? It looks like there isn't a strongly typed delegate for this and I'm having trouble figuring out what selectors I need to handle on the delegates of my InputStream and OutputStream and what I actually need to do with each selector in order to properly fill and empty the buffers belonging to the EASession object. Basically, I'm trying to port Apple's EADemo app to Monotouch right now. Here's the Objective-C source that I think is relevant to this problem: / / asynchronous NSStream handleEvent method - (void)stream:(NSStream *)aStream handleEvent:(NSStreamEvent)eventCode { switch (eventCode) { case NSStreamEventNone: break; case NSStreamEventOpenCompleted: break; case NSStreamEventHasBytesAvailable: [self _readData]; break; case NSStreamEventHasSpaceAvailable: [self _writeData]; break; case NSStreamEventErrorOccurred: break; case NSStreamEventEndEncountered: break; default: break; } } / low level write method - write data to the accessory while there is space available and data to write - (void)_writeData { while (([[_session outputStream] hasSpaceAvailable]) && ([_writeData length] > 0)) { NSInteger bytesWritten = [[_session outputStream] write:[_writeData bytes] maxLength:[_writeData length]]; if (bytesWritten == -1) { NSLog(@"write error"); break; } else if (bytesWritten > 0) { [_writeData replaceBytesInRange:NSMakeRange(0, bytesWritten) withBytes:NULL length:0]; } } } // low level read method - read data while there is data and space available in the input buffer - (void)_readData { #define EAD_INPUT_BUFFER_SIZE 128 uint8_t buf[EAD_INPUT_BUFFER_SIZE]; while ([[_session inputStream] hasBytesAvailable]) { NSInteger bytesRead = [[_session inputStream] read:buf maxLength:EAD_INPUT_BUFFER_SIZE]; if (_readData == nil) { _readData = [[NSMutableData alloc] init]; } [_readData appendBytes:(void *)buf length:bytesRead]; //NSLog(@"read %d bytes from input stream", bytesRead); } [[NSNotificationCenter defaultCenter] postNotificationName:EADSessionDataReceivedNotification object:self userInfo:nil]; } I'd also appreciate any architectural recommendations on how to best implement this in monotouch. For example, in the Objective C implementation these functions are not contained in any class--but in Monotouch would it make sense to make them members of my

• boost smart pointers and BOOST_NO_MEMBER_TEMPLATES

  - by Johann Gerell

  After some struggling I managed to get boost smart pointers to build for Windows CE/Mobile at warning level 4. I found the least-resistance-way to get rid of compile errors and warnings to be #define BOOST_NO_MEMBER_TEMPLATES What does it actually mean? Did I sell my soul to the devil? Will all hell break loose when I actually use the types?

• Where is the VM in LLVM?

  - by anon

  Note: marked as community wiki. Where is the Low Level Virtual Machine in LLVM? I see that we have llvm-g++ and c-lang, but to me, a LLVM is something almost like Valgrind of a simulator, where instructions are executed on it, and I can write programs to instrument the running code / interrupt when certain conditions happen / etc ... Where are the tools like this built on LLVM? Thanks!

• Beginner python - stuck in a loop

  - by Jeremy

  I have two begininer programs, both using the 'while' function, one works correctly, and the other gets me stuck in a loop. The first program is this; num=54 bob = True print('The guess a number Game!') while bob == True: guess = int(input('What is your guess? ')) if guess==num: print('wow! You\'re awesome!') print('but don\'t worry, you still suck') bob = False elif guess>num: print('try a lower number') else: print('close, but too low') print('game over')`` and it gives the predictable output of; The guess a number Game! What is your guess? 12 close, but too low What is your guess? 56 try a lower number What is your guess? 54 wow! You're awesome! but don't worry, you still suck game over However, I also have this program, which doesn't work; #define vars a = int(input('Please insert a number: ')) b = int(input('Please insert a second number: ')) #try a function def func_tim(a,b): bob = True while bob == True: if a == b: print('nice and equal') bob = False elif b > a: print('b is picking on a!') else: print('a is picking on b!') #call a function func_tim(a,b) Which outputs; Please insert a number: 12 Please insert a second number: 14 b is picking on a! b is picking on a! b is picking on a! ...(repeat in a loop).... Can someone please let me know why these programs are different? Thank you!

• SQL Where Clause Against View

  - by Adam Carr

  I have a view (actually, it's a table valued function, but the observed behavior is the same in both) that inner joins and left outer joins several other tables. When I query this view with a where clause similar to SELECT * FROM [v_MyView] WHERE [Name] like '%Doe, John%' ... the query is very slow, but if I do the following... SELECT * FROM [v_MyView] WHERE [ID] in ( SELECT [ID] FROM [v_MyView] WHERE [Name] like '%Doe, John%' ) it is MUCH faster. The first query is taking at least 2 minutes to return, if not longer where the second query will return in less than 5 seconds. Any suggestions on how I can improve this? If I run the whole command as one SQL statement (without the use of a view) it is very fast as well. I believe this result is because of how a view should behave as a table in that if a view has OUTER JOINS, GROUP BYS or TOP ##, if the where clause was interpreted prior to vs after the execution of the view, the results could differ. My question is why wouldn't SQL optimize my first query to something as efficient as my second query?

• What happens when Oracle's Enterprise Single-Sign-On database goes down? [migrated]

  - by Unai

  We're working on setting up Oracle's Enterprise Single-Sign-On with High Availability. At the moment every component provides HA except our database backend (i.e. we have just one instance). While conducting some kick-the-plug tests we learnt that the ESSO system works even with the database turned OFF. This was a nice surprise but now we need to understand what are the implications of a database failure; sure the sessions might be handled on the application servers and the policies might have been cached but... for how long? how big is this cache? what is the role of the database? I would appreciate if anyone shares her/his experience and/or points out to documentation that covers this. Thank you so much.

• HLSL tex2d sampler seemingly returning incorrect values; why?

  - by BlueNovember

  Hello all, I have code that needs to render regions of my object differently depending on their location. I am trying to use a colour map to define these regions, then get a value (0-14) representing this region by sampling the texture. The problem is when I sample from my colour map, I get collisions. Ie, two regions with different colours in the colourmap get the same value returned from the sampler. I've tried various formats of my colour map. I set the colours for each region to be "5" apart in each case; Indexed colour RGB, RGBA: region 1 will have RGB 5,5,5. region 2 will have RGB 10,10,10 and so on. HSV Greyscale: region 1 will have HSV 0,0,5. region 2 will have HSV 0,0,10 and so on. The tex2D sampler returns a value [0..1]. To get the "region number" I multiply this by 100 and divide by 5, expecting a number [0..20]. (But currently only using 0-14) I am using Shader Model 2 and FX Composer. //Colour map texture gColourmapTexture < string ResourceName = "Globe_Colourmap_Regions_Greyscale.png"; string ResourceType = "2D"; >; sampler2D gColourmapSampler : register(s1) = sampler_state { Texture = <gColourmapTexture>; #if DIRECT3D_VERSION >= 0xa00 Filter = MIN_MAG_MIP_LINEAR; #else /* DIRECT3D_VERSION < 0xa00 */ MinFilter = Linear; MipFilter = Linear; MagFilter = Linear; #endif /* DIRECT3D_VERSION */ AddressU = Clamp; AddressV = Clamp; }; ... //Then later, in a method float region = tex2D(gColourmapSampler,In.UV).x; //at this point I do not think it matters which of xyz components I pick; even in HSV they're all the same for my image. region *= 100; //Now in range [0..100] region /= 5; //Now in range [0..20] float3 levels[21]; //*Code populating "levels" array with what is essentially colour information * levels[1] = ... levels[2] = ... //Chose which level this region has, by looking up its region number float3 Level = levels[region];

• Is there a fast way to jump to element using XMLReader?

  - by Derk

  I am using XMLReader to read a large XML file with about 1 million elements on the level I am reading from. However, I've calculated it will take over 10 seconds when I jump to -for instance- element 500.000 using XMLReader::next ([ string $localname ] ) or XMLReader::read ( void ) This is not very usable. Is there a faster way to do this?

• PHP Performance Metrics

  - by bigstylee

  I am currently developing a PHP MVC Framework for a personal project. While I am developing the framework I am interested to see any notable performance by implementing different techniques for optimization. I have implemented a crude BenchMark class that logs mircotime. The problem is I have no frame of reference for execution times. I am very near the beginnig of this project with a database connection and a few queries but no output (bar some debugging text and BenchMark log). I have a current execution time of 0.01917 seconds. I was expecting this to be lower but as I said before I have no frame of reference. I appreciate there are many variables to take into account when juding performance but I am hoping to find some sort of metric to a) techniques to measure performance for example requests per second and b) compare results for example; how a "moderately" sized PHP application on a "standard" webserver will perform. I appreciate "moderately" and "standard" are very subjective words so perhaps a table of known execution times for a particular application (eg StackOverFlow's executing time). What are other techniques of measuring performance are there other than execution time? When looking at MVC Framework Performance Comparisom it talks about Requests Per Second (RPS). How is this calculated? I am guessing with my current execution time of 0.01917 seconds can handle 52 RPS (= 1 / 0.01917 ). This seems to be significantly lower than that quoted on the graph especially when you consider my current limited funcitonality.

• Debugging mod_rewrite

  - by nickf

  I'm playing around with Apache's mod_rewrite module, and want to know if there is a decent way to output some debugging information? For example, the documentation lists a number of variables available: %{HTTP_USER_AGENT}, %{HTTP_REFERER}, %{HTTP_COOKIE} ... etc Is there a way I could output these just to see what I'm working with? I set up the RewriteLog (Level 2) and have been looking at that, but it'd be nice to be able to see the value of the variables.

• Problem with the hosts file in Windows XP

  - by Mee

  I have a computer with Windows XP SP2 with a weird problem. The hosts file doesn't work. No matter what I do, adding or removing entries in the file doesn't make any difference, pinging the added names times out. I tried flushing the DNS cache (using ipconfig /flushdns) but that didn't work, I even tried to restart the DNS client service but that made no difference too. Removing entries also has no effect, I ping the names and I get a reply. Help!!! Edit: Thanks for your answer guys, but the problem is more complicated than this. It seems I'll have to reinstall Windows.

• Accessing Arguments, Workflow Variables from custom activities

• New CATransform3DMakeRotation deletes old transformation?!

  I added a CATransform3DMakeRotation to a layer. When I add another one it deletes the old one? The first one: [UIView beginAnimations:@"rotaty" context:nil]; [UIView setAnimationDuration:0.5]; [UIView setAnimationDelegate:self]; CGAffineTransform transform = CGAffineTransformMakeRotation(-3.14); kuvert.transform = CGAffineTransformRotate(transform, DegreesToRadians(134)); kuvert.center = CGPointMake(kuvert.center.x-70, kuvert.center.y+100); [UIView commitAnimations]; and the second one: CABasicAnimation *topAnim = [CABasicAnimation animationWithKeyPath:@"transform"]; topAnim.duration=1; topAnim.repeatCount=0; topAnim.fromValue = [NSValue valueWithCATransform3D:CATransform3DMakeRotation(0.0, 0, 0, 0)]; float f = DegreesToRadians(180); // -M_PI/1; topAnim.toValue=[NSValue valueWithCATransform3D:CATransform3DMakeRotation(f, 0,1, 0)]; topAnim.delegate = self; topAnim.removedOnCompletion = NO; topAnim.fillMode = kCAFillModeBoth; [topAnim setValue:@"flippy" forKey:@"AnimationName"]; [[KuvertLasche layer] addAnimation:topAnim forKey:@"flippy"]; The second one resets the view and applies itself after that.

• KVM Guest installed from console. But how to get to the guest's console?

  - by badbishop

  I'm trying to install a fully virtualized guest (Fedora 14 x86_64) on KVM (RHEL 6), using command-line only (both hypervisor and guest). It goes without errors, and without a tangible result . I'd like to know how to do a text-only installation.

As I understand after googling for a couple of days, I should see the guest's output from the text installation, but nothing happens. virt-viewer cannot connect to it, kindly suggesting that I explore all the options by adding --help (which I did). If I reconnect with virsh, I see this: Domain installation still in progress. You can reconnect to the console to complete the installation process.

• Rotation Portrait Landscape with 2 XIB

  - by Ploetzeneder

  Hello, i have got 2 GUIs and 2 Controllers 1 is called landscapeguicontroller and the second is called highguicontroller. Now generally i call the highguicontroller, and when i rotate my iphone it detects that and then it shows the landscapeguicontroller: Code: landscapeguicontroller *neu =[[landscapeguicontroller alloc] initWithNibName:nil bundle:nil]; [self presentModalViewController:neu animated:YES]; [self dismissModalViewControllerAnimated:YES]; The Problem is that then the animation pushes the new window from the beyond side of the iphone up into the window. In the Landscapeguicontroller,i have added to the the following lines: Code: (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return (interfaceOrientation == UIInterfaceOrientationPortrait); } when i want go back to the highguicontroller i call: [self dismissModalViewControllerAnimated:YES]; that all works , but just in the second animation i see the correct "rotation animation". Have you got any suggestions? So a short Problem description: in the 1. animation from high to landscape, the landscape is pushed into the window BUT in the 2. animation from landscape to high, the rotation looks like a real rotation... i want the 1.animation look like the 2. animation best regards Ploetzeneder

It's a relatively popular site and I fear that during propagation orders will be split between the old database and the new one. The databases do contain content that is dependent of the server it is on (Cache path, upload directory, etc.) so I can't just point the old site to the new database. Are there any solutions to this without any of the sites going down. Thanks in advance

• Python MD5 Hash Faster Calculation

  - by balgan

  Hi everyone. I will try my best to explain my problem and my line of thought on how I think I can solve it. I use this code for root, dirs, files in os.walk(downloaddir): for infile in files: f = open(os.path.join(root,infile),'rb') filehash = hashlib.md5() while True: data = f.read(10240) if len(data) == 0: break filehash.update(data) print "FILENAME: " , infile print "FILE HASH: " , filehash.hexdigest() and using start = time.time() elapsed = time.time() - start I measure how long it takes to calculate an hash. Pointing my code to a file with 653megs this is the result: root@Mars:/home/tiago# python algorithm-timer.py FILENAME: freebsd.iso FILE HASH: ace0afedfa7c6e0ad12c77b6652b02ab 12.624 root@Mars:/home/tiago# python algorithm-timer.py FILENAME: freebsd.iso FILE HASH: ace0afedfa7c6e0ad12c77b6652b02ab 12.373 root@Mars:/home/tiago# python algorithm-timer.py FILENAME: freebsd.iso FILE HASH: ace0afedfa7c6e0ad12c77b6652b02ab 12.540 Ok now 12 seconds +- on a 653mb file, my problem is I intend to use this code on a program that will run through multiple files, some of them might be 4/5/6Gb and it will take wayy longer to calculate. What am wondering is if there is a faster way for me to calculate the hash of the file? Maybe by doing some multithreading? I used a another script to check the use of the CPU second by second and I see that my code is only using 1 out of my 2 CPUs and only at 25% max, any way I can change this? Thank you all in advance for the given help.

• Beginner SQL question: querying gold and silver tag badges in Stack Exchange Data Explorer

  - by polygenelubricants

  I'm using the Stack Exchange Data Explorer to learn SQL, but I think the fundamentals of the question is applicable to other databases. I'm trying to query the Badges table, which according to Stexdex (that's what I'm going to call it from now on) has the following schema: Badges Id UserId Name Date This works well for badges like [Epic] and [Legendary] which have unique names, but the silver and gold tag-specific badges seems to be mixed in together by having the same exact name. Here's an example query I wrote for [mysql] tag: SELECT UserId as [User Link], Date FROM Badges Where Name = 'mysql' Order By Date ASC The (slightly annotated) output is: as seen on stexdex: User Link Date --------------- ------------------- // all for silver except where noted Bill Karwin 2009-02-20 11:00:25 Quassnoi 2009-06-01 10:00:16 Greg 2009-10-22 10:00:25 Quassnoi 2009-10-31 10:00:24 // for gold Bill Karwin 2009-11-23 11:00:30 // for gold cletus 2010-01-01 11:00:23 OMG Ponies 2010-01-03 11:00:48 Pascal MARTIN 2010-02-17 11:00:29 Mark Byers 2010-04-07 10:00:35 Daniel Vassallo 2010-05-14 10:00:38 This is consistent with the current list of silver and gold earners at the moment of this writing, but to speak in more timeless terms, as of the end of May 2010 only 2 users have earned the gold [mysql] tag: Quassnoi and Bill Karwin, as evidenced in the above result by their names being the only ones that appear twice. So this is the way I understand it: The first time an Id appears (in chronological order) is for the silver badge The second time is for the gold Now, the above result mixes the silver and gold entries together. My questions are: Is this a typical design, or are there much friendlier schema/normalization/whatever you call it? In the current design, how would you query the silver and gold badges separately? GROUP BY Id and picking the min/max or first/second by the Date somehow? How can you write a query that lists all the silver badges first then all the gold badges next? Imagine also that the "real" query may be more complicated, i.e. not just listing by date. How would you write it so that it doesn't have too many repetition between the silver and gold subqueries? Is it perhaps more typical to do two totally separate queries instead? What is this idiom called? A row "partitioning" query to put them into "buckets" or something?

• "Access 2002 vs SQL Server 200*" as DB for sharepoint

  - by Jake

  I work with a team that has a sharepoint site currently runnning and its lists are linked to an access DB. My question is really on the investment level, what would be the reasons to upgrade DB to sharepoint if only a few 100 users access this site. Is there a real benefit to replacing the DB with a version of SQL Server, escpecially if about to replace Access 2002 with 2007 some day. I know SQL Server can handle more memory and traffic for more users, but I'm looking for more reasons than that if there are any.

• How can I permanently remove default root hints from a Server 2008 DNS server?

  - by TonyD

  My network exists in private address space and I am unable to perform DNS lookups against DNS servers on the internet directly (blocked by firewall). There are other networks that exist in the same private address space as my network. I need to be able to perform DNS lookups for devices in these networks as well. There are 2 main internal DNS servers in this private address space, but not on my netowrk. I can perform DNS lookups against both of these servers for devices internal to our address space and names on the internet. I would like to permanently remove the root hints from our Server 2008 R2 DNS server and replace them with these 2 internal DNS servers. I have removed them from the dnsmgmt console, the C:\Windows\System32\DNS\cache.dns file, and from the RootDNSServers folder under the System folder in ADUC. Even so, they continue to repopulate into the root hints tab in the server properties for DNS after roughly an hour. Does anyone know how to permanently remove these entries?
