• Script to UPDATE STATISTICS with time window

  - by Bill Graziano

  I recently spent some time troubleshooting odd query plans and came to the conclusion that we needed better statistics.  We’ve been running sp_updatestats but apparently it wasn’t sampling enough of the table to get us what we needed.  I have a pretty limited window at night where I can hammer the disks while this runs.  The script below just calls UPDATE STATITICS on all tables that “need” updating.  It defines need as any table whose statistics are older than the number of days you specify (30 by default).  It also has a throttle so it breaks out of the loop after a set amount of time (60 minutes).  That means it won’t start processing a new table after this time but it might take longer than this to finish what it’s doing.  It always processes the oldest statistics first so it will eventually get to all of them.  It defaults to sample 25% of the table.  I’m not sure that’s a good default but it works for now.  I’ve tested this in SQL Server 2005 and SQL Server 2008.  I liked the way Michelle parameterized her re-index script and I took the same approach.

• Question about using ServiceModelEx's "WCFLogbook" from "Programming WCF Services" book

  - by Bill

  I am attempting to compile/run a sample WCF application from Juval Lowy's website (author of Programming WCF Services & founder of IDesign). Of course the example application utilizes Juval's ServiceModelEx library and logs faults/errors to a "WCFLogbook" database. Unfortunately, when the sample app faults, I get the following new error: "Cannot open database "WCFLogbook" requested by the login. The login failed. Login failed for user 'Bill-PC\Bill'." I suspect the error occurs as a result of not finding the "WCFLogbook" database, which I believe still needs to be created. Included in the library source directory, there are two files -WCFLogbookDataSet.xsd and WCFLogbook.sql; which neither seem to be referenced anywhere within the library code. This leads me to beleive that the sql and xsd files are there to be used to create the database somehow in SQL. Could someone please advise me if I am going in the correct direction here and if whether these files can be used to create the database (and if so, how)?

• Permissions issue Mac OS X Client -> Mac OS X Server

  - by Meltemi

  I can't get access to a folder on our server and can't understand why. Perhaps someone will see what I'm overlooking... Trouble accessing /Library/Subdirectory/NextDirectory/ User joe can ssh to the server just fine and cd to /Library/Subdirectory/ however trying to cd into the next folder, NextDirectory, gives this error: -bash: cd: NextDirectory/: Permission denied both username joe & bill are members of the group admin and both can get INTO Subdirectory without any trouble... hostname:Library joe$ ls -l | grep Subdirectory drwxrwxr-x 3 bill admin 102 Jun 1 14:51 Subdirectory and from w/in the Subversion folder hostname:Subdirectory joe$ ls -l drwxrwx--- 5 root admin 170 Jun 1 22:19 NextDirectory bill can cd into NextDirectory but joe cannot!?! What am I overlooking? What tools do we have to troubleshoot this? thanks!

• Login failed--password of account must be changed--error 18488

  - by Bill Paetzke

  I failed to connect to a production SQL server. My administrator reset my password, and told me what it was. SQL Server Management Studio gives me this error: Login failed for user 'Bill'. Reason: The password of the account must be changed. (Microsoft SQL Server, Error: 18488) So, how can I reset my password? I tried terminaling into the server with this account, but it said that account doesn't exist. So I guess it's not a regular server account--just SQL server. (if that helps)

• How do I protect business critical data against fire?

  - by Bill Knowles

  We have 72 hard drives that contain our webcast inventory. The number is increasing. We're located in a frame building and we are afraid of not only fire, but catastrophic fire. I've priced fireproof safes that hold to the required 125F for hard drives. Their price is through the roof. Seems to me if we made backups of each of the hard drives and stored them off-site somewhere, or contracted with an online backup storage company, we might run up a bill buying backup drives that would approach the $7,000 cost of the safe! What's the best way to protect our data from the risk of fire?

• Linux Router - Share bandwidth per IPs with current active connections

  - by SRoe

  We have a Linux machine running as a custom router, currently utilising Shorewall. This sits between our incoming internet connection and the internal LAN. What we would like to achieve is 'fair use' of the bandwidth on a per IP basis. If only one person currently has an active connection then they get 100% utilisation of the line. However if 20 people have active connections then they should each get 5% utilisation of the line. This should be irrespective of the number of connections held by each user. For example, say we have two users, Bill and Ted, that both have active connections. Bill has a single active connection while Ted has ten active connections. Bill should get 50% utilisation for his single connections whilst Ted should get 5% utilisation for each of his ten connections, giving Ted a total utilisation of 50%.

• Nested IF statement on Google Spreadsheet, second part same as the first [migrated]

  - by lazfish

  I have a spreadsheet for my budget. Payments are either drawn from my bank or my Amex card and then my Amex card is drawn from my bank as well. So I add up all my monthly total like this: =sumif(I3:I20,"<>AMEX",D3:D20) Where I3:I20 = account bill is paid from and D3:D20 is monthly amount due. So I am not including bills that come from my Amex card in the total since the Amex bill itself covers those. Next I have a column that has the day of the month 1-10 (when everything gets paid) and it does this: =sumif(H3:H20,E24:E33,D3:D20) Where H3:H20 = date bill is paid and E25:E35 = range from 1-10. What I want to do is make this second part do the same check as the first. Something like this: =sumif(H3:H19,E24:E33,IF(I3:I19"<>SPG",D3:D19,0)) But I get error: "Parse error" What am I doing wrong?

• CDN with South America peering points / edge nodes

  - by Bill

  Hello, Does anyone one know of a CDN (Content Delivery Network) with true South American peering points or edge nodes? This seems to be quite rare. It seems that most CDNs serve Central and South America from Texas. However, our application requires low latency in Brazil, so this is not a good solution for us. We would like to avoid having to set up servers in South America just for this piece of the application, but may end up doing that. Thanks, Bill

  If I have an example such as the following: describe "A flux capacitor" do it "should flux a lot" do # how can I access the string object "A flux capacitor" in here??? ... end end How can I access the described string object "A flux capacitor"? I've tried a few permutations of 'described_type' and 'described_class' Such as: self.described_type.to_s But these always return nothing. What am I doing wrong? Thanks, -Bill

• How to Route Traffic in Case PPTP Remote Client is on Same Subnet as Server

  - by Marcus Cole

  I've a PPTP server setup on my local home network (192.168.1.0/24, pfSense). Now sometimes when I'm away and want to connect remotely my client (Windows 7) is also on the same network because e.g. the hotel has set it up the same way. Thus the connection works, but I can't reach any PC on my home network because everything is routed directly to the client local router which is in the same subnet. Is there a way to work around this by messing with a configuration or adapting Windows routing table, i.e. without modifying either network?

• IPFW not locking people out

  - by Cole

  I've had some brute-forcing of my ssh connection recently, so I got fail2ban to hopefully prevent that. I set it up, and started testing it out by giving wrong passwords on my computer. (I have physical access to the server if I need to unblock myself) However, it never stops me from entering passwords. I see in /var/log/fail2ban.log that fail2ban kicked in and banned me, and there's a ipfw entry for my IP, but I'm not locked out. I've changed the configuration around, and then tried just using the ipfw command myself, but nothing seems to lock me out. I've tried the following blocks: 65300 deny tcp from 10.0.1.30 to any in 65400 deny ip from 10.0.1.30 to any 65500 deny tcp from 10.0.1.30 to any My firewall setup has a "allow ip from any to any" rule after these though, maybe that's the problem? I'm using Mac OS 10.6 (stock ipfw, it doesn't seem to have a --version flag) Thanks in advance.

• How to tell if Microsoft Works is 32 or 64 bit? Please Help!

  - by Bill Campbell

  Hi, I am trying to convert one of our apps to run on Win7 64 bit from XP 32 bit. One of the things that it uses is Excel to import files. It's a little complicated since it was using Microsoft.Jet.OLEDB.4.0 (Excel). I found Office 14 (2010) has a 64bit version I can download. I downloaded Office 2010 Beta but it didn't seem to install Microsoft.ACE.OLEDB.14.0. I found that I could download 2010 Office System Driver Beta: Data Connectivity Components which has the ACE.OLEDB.14 in it but when I try to install it, the installed tells me "You cannot install the 64-bit version of Access Database engine for Microsoft Office 2010 because you currently have 32-bit Office products installed". How do I determine what 32bit office products this is reffering to? My Dell came with Microsoft Works installed. I don't know if this is 32 or 64 bit. Is there anyway to tell? I don't want to uninstall this if it's not the problem and I'm not sure what else might be the problem. Any help would be appreciated! thanks, Bill

• Is there any open source tool that automatically 'detects' email threading like Gmail?

  - by Chris W.

  For instance, if the original message (message 1) is... Hey Jon, Want to go get some pizza? -Bill And the reply (message 2) is... Bill, Sorry, I can't make lunch today. Jonathon Parks, CTO Acme Systems On Wed, Feb 24, 2010 at 4:43 PM, Bill Waters wrote: Hey John, Want to go get some pizza? -Bill In Gmail, the system (a) detects that message 2 is a reply to message 1 and turns this into a 'thread' of sorts and (b) detects where the replied portion of the message actually is and hides it from the user. (In this case the hidden portion would start at "On Wed, Feb..." and continue to the end of the message.) Obviously, in this simple example it would be easy to detect the "On <Date, <Name wrote:" or the "" character prefixes. But many email systems have many different style of marking replies (not to mention HTML emails). I get the feeling that you would have to have some damn smart string parsing algorithms to get anywhere near how good GMail's is. Does this technology already exist in an open source project somewhere? Either in some library devoted to this exclusively or perhaps in some open source email client that does similar message threading? Thanks.

• Unable to terminate extra EC2 instances

  - by Deborah Cole

  I'm just setting up my AWS server & I'm trying to use the EC2 Console to terminate some extra instances that I generated via the AWS for Eclipse toolkit's New Project AWS Java Web Project utility. Unfortunately, every time I stop, then terminate such an instance via the EC2 Console, it automatically recreates & reactivates itself! I really don't want to be paying for 4 dev systems when I only need 1, so can somebody please clue me in? Please explain gently... I'm new to this environment.

• Which IMAP flags are reliably supported across most mail servers?

  - by Ben Butler-Cole

  I am writing an application which reacts to emails sent to a mailbox. It retrieves the emails via IMAP. It will be deployed to a number of systems where I do not control the mail server configuration. I would like to use IMAP flags to indicate which messages have been handled. Are the system flags sufficiently widely supported that I can reasonably depend on them in my application? Are user-defined flags sufficiently widely supported? (If the answer is "ha ha, not a chance", then I shall use folders instead.) Thanks -Ben

• Raid-5 Performance per spindle scaling

  - by Bill N.

  So I am stuck in a corner, I have a storage project that is limited to 24 spindles, and requires heavy random Write (the corresponding read side is purely sequential). Needs every bit of space on my Drives, ~13TB total in a n-1 raid-5, and has to go fast, over 2GB/s sort of fast. The obvious answer is to use a Stripe/Concat (Raid-0/1), or better yet a raid-10 in place of the raid-5, but that is disallowed for reasons beyond my control. So I am here asking for help in getting a sub optimal configuration to be as good as it can be. The array built on direct attached SAS-2 10K rpm drives, backed by a ARECA 18xx series controller with 4GB of cache. 64k array stripes and an 4K stripe aligned XFS File system, with 24 Allocation groups (to avoid some of the penalty for being raid 5). The heart of my question is this: In the same setup with 6 spindles/AG's I see a near disk limited performance on the write, ~100MB/s per spindle, at 12 spindles I see that drop to ~80MB/s and at 24 ~60MB/s. I would expect that with a distributed parity and matched AG's, the performance should scale with the # of spindles, or be worse at small spindle counts, but this array is doing the opposite. What am I missing ? Should Raid-5 performance scale with # of spindles ? Many thanks for your answers and any ideas, input, or guidance. --Bill Edit: Improving RAID performance The other relevant thread I was able to find, discusses some of the same issues in the answers, though it still leaves me with out an answer on the performance scaling.

• 2 HP Procurve 4000M switches and Comcast SMC Gateway

  - by Cole Tierney

  We've got 2 HP Procurve 4000M switches joined by a trunk. Switch 1 is connected to a Cisco 2600 router which is connected to a T1. Internet traffic for hosts on switch 2 must pass through the trunk to switch 1. We're now switching to Comcast who's given us 4 port SMC router. I would like to connect each switch to the comcast router to reduce traffic on the trunk, but I don't want to create a loop. The switches support spanning tree protocol, but I don't know how this would work with the comcast router. Would a triangle network like this work? Thanks for any tips.

• Dell laptop doesn't wake from hibernation after installing Windows 8.1

  - by Mike Cole

  My laptop worked flawlessly before upgrade to Windows 8.1 from 8. Now when I close the lid of my laptop and it goes into hibernation, it will not wake again. The LED lights seem to work properly but I don't get any video. I have to hold the power key to turn off then turn it back on again. It wakes from sleep properly. All Windows Updates have been installed. There are 2-3 items in the Device Manager that do not have compatible 8.1 drivers, but I believe those are security related items like fingerprint scanner.

• Windows 7 doesn't show image size for all images

  - by Cole Johnson

  On Windows 7's new file layout in Explorer. Some PNGs will show the size whereas others won't. I've tried rebooting and clearing the cache, but it doesn't work. Also, all of these images were saved with Paint.NET, so I am sure that the size isn't embeded in the file, and if it is, it appears that Windows doesn't go by it. The ones without sizes are 300x300. Is there a maximum size before it won't show the size anymore?

• How can I create a new Person object correctly in Javascript?

  - by TimDog

  I'm still struggling with this concept. I have two different Person objects, very simply: ;Person1 = (function() { function P (fname, lname) { P.FirstName = fname; P.LastName = lname; return P; } P.FirstName = ''; P.LastName = ''; var prName = 'private'; P.showPrivate = function() { alert(prName); }; return P; })(); ;Person2 = (function() { var prName = 'private'; this.FirstName = ''; this.LastName = ''; this.showPrivate = function() { alert(prName); }; return function(fname, lname) { this.FirstName = fname; this.LastName = lname; } })(); And let's say I invoke them like this: var s = new Array(); //Person1 s.push(new Person1("sal", "smith")); s.push(new Person1("bill", "wonk")); alert(s[0].FirstName); alert(s[1].FirstName); s[1].showPrivate(); //Person2 s.push(new Person2("sal", "smith")); s.push(new Person2("bill", "wonk")); alert(s[2].FirstName); alert(s[3].FirstName); s[3].showPrivate(); The Person1 set alerts "bill" twice, then alerts "private" once -- so it recognizes the showPrivate function, but the local FirstName variable gets overwritten. The second Person2 set alerts "sal", then "bill", but it fails when the showPrivate function is called. The new keyword here works as I'd expect, but showPrivate (which I thought was a publicly exposed function within the closure) is apparently not public. I want to get my object to have distinct copies of all local variables and also expose public methods -- I've been studying closures quite a bit, but I'm still confused on this one. Thanks for your help.
