• MSSQL: Choice of service accounts

  - by Troels Arvin

  When installing MS SQL Server 2008, one needs to associate a service account with the installation (possibly even several accounts, one for the SQL Server Agent, one for Analysis Services, ..., but let's leave that for the case of simplicity). The service account may be local account, or a Windows domain account. If a domain account is used: Can MSSQL start, if connectivity to the domain controllers is temporarily down? If the answer is yes: Should each DBMS instance on each server have a separate account, or does it make sense to use a particular "MSSQL" domain account on all MSSQL-installations in the organization? If separate accounts are used for each instance on each server: Does it make sense to create a special MSSQL security group in the domain and place all the MSSQL service accounts in that group, perhaps to ease replication, etc? Is there a common, generally accepted naming convention for MSSQL service account(s)?

• Microsoft WPC 12&ndash;Predictions

  - by D'Arcy Lussier

  Let me start by saying I have absolutely no inside knowledge, neither through the MVP program or any other means, that is fuelling what I’m about to write. This is entirely conjecture fuelled by speculation and too much Soporro beer at a fantastic Japanese restaurant tonight. Still, I present to you… D’Arcy’s Worldwide Partner Conference 2012 Predictions!!! So what can we expect to be announced at this year’s WPC? Much more than last year I’m hoping! Last year was sort of encouraging the troops to carry on with the Windows 7 messaging even with Windows 8 looming in the distance. It also showed Microsoft’s slant towards Private Cloud in addition to Azure. This year, we’re going to see a shift to a battle cry – Windows 8 is Coming, Windows 8 is Coming! I expect we’re going to hear an RTM date for Windows 8 from Steve Ballmer tomorrow, in addition to dates surrounding Windows Server 2012. We’ll also hear some announcement around Windows Phone 8, but I’m not really sure what – that whole piece is still quite muddy; are we going to actually *see* Windows Phone 8 devices this week? That would be great, but I imagine those types of announcements might be left for Build. Speaking of Build, I’m expecting an announcement on a date for a Build conference this Fall, probably late October. If any announcements are going to be made around Office 15, the schedule isn’t hinting at it. In fact, other than Office 365 there’s not much mention of Office in the conference sessions – either a red herring, or telling that Microsoft has another announcement coming later. The tagline of the conference is “A New Era. Together.” It’s obvious Microsoft is wanting to leverage WPC to rally their partners to carry the Windows 8 banner into the field of battle this fall when it ships. D

• Is this a ridiculous way to structure a DB schema, or am I completely missing something?

  - by Jim

  I have done a fair bit of work with relational databases, and think I understand the basic concepts of good schema design pretty well. I recently was tasked with taking over a project where the DB was designed by a highly-paid consultant. Please let me know if my gut intinct - "WTF??!?" - is warranted, or is this guy such a genius that he's operating out of my realm? DB in question is an in-house app used to enter requests from employees. Just looking at a small section of it, you have information on the users, and information on the request being made. I would design this like so: User table: UserID (primary Key, indexed, no dupes) FirstName LastName Department Request table RequestID (primary Key, indexed, no dupes) <...> various data fields containing request details UserID -- foreign key associated with User table Simple, right? Consultant designed it like this (with sample data): UsersTable UserID FirstName LastName 234 John Doe 516 Jane Doe 123 Foo Bar DepartmentsTable DepartmentID Name 1 Sales 2 HR 3 IT UserDepartmentTable UserDepartmentID UserID Department 1 234 2 2 516 2 3 123 1 RequestTable RequestID UserID <...> 1 516 blah 2 516 blah 3 234 blah The entire database is constructed like this, with every piece of data encapsulated in its own table, with numeric IDs linking everything together. Apparently the consultant had read about OLAP and wanted the 'speed of integer lookups' He also has a large number of stored procedures to cross reference all of these tables. Is this valid design for a small to mid-sized SQL DB? Thanks for comments/answers...

• The advantages & disadvantages to be had from using a Web Framework?

  - by JHarley1

  Hello, This question is focused on extracting the advantages and disadvantages of using Web based Frameworks: such as Cake PHP, Zend, jQuery, ASP.NET). This question is completely language agnostic. Let me start with the notion of "Standing on the shoulders of Giants". Advantages: Empowers Developers - by taking features that would have previously have taken 100's of lines of code and compressing them into one simple function call empowers developers to integrate more complex features into their Web Sites. Allow for Quicker development of applications - this is very relevant for people that need websites created in a very small window (has anyone any examples of this?) Lower Costs - allows programmers to pass cost savings onto the customer, a whole new range of customers generated that wanted a website but previously could not afford the higher development costs. Disadvantages: Lost Understanding - by relying on the features of a framework a developer is in danger of loosing understanding on how things work (underneath the hood). The configuration cliff - once you go further than the configuration of your framework your productivity drops right off, it can be difficult to implement features outside of a frameworks configuration. Developer tramlines - you (the developer) has to do things the way that the developer want you to do things. Security issues - giving people these tools to develop professional looking websites fast is a potential risk, people can quickly create professional looking websites for fraudulent companies. I wonder what people make of my points, and whether any body disagrees with them? Also if people have additional points I would be grateful. Many Thanks, J

• Where is he now?

  - by Chris G. Williams

  A couple months ago, I announced I was leaving Magenic in order to take a break from consulting. I figured I'd post an update as to what I'm doing now, since I haven't exactly been slacking off.1) I accepted a position as a Lead Developer with RealPage. I work on a number of internal use applications for a subsidiary known as LevelOne. The majority of my work is in ASP.NET, a surprising amount of VB.NET, some C# and I'm picking up a few new tools for my belt... specifically Python, MongoDB and Perl.2) I am still the owner of Big Robot Games, a retail game store / coffee shop in the South Carolina upstate region. I'm not as involved in the day to day activity as I was, but I'm there most nights and weekends, when I'm not off doing other things, like #3.3) I am on the staff of Rock Revolt Magazine as a journalist, covering live performances as well as interviewing bands, providing album & video game reviews, fixing the website and the occasional prison ink. (Just kidding on that last one.)4) In whatever time is leftover, I still manage to bang out a little code on Heroic Adventure! (aka HA!) and talk about Windows Phone, XNA and whatever else suits me, wherever they'll let me.I guess that's about it.

• Dedicated server: managed hosting or manage it myself?

  - by ddawber

  We're currently hosting a number of sites on a self-managed dedicated server. Some companies, however, offer a managed dedicated server hosting service. They offer: Roughly the same server spec Ticketing system support Managed daily backups Virtual firewall (but with a limit of 10 IP addresses allowed through at any one time) Now, this managed hosting is at extra expense - somewhere in the region of $500 per month, and the limit on the number of IP addresses they'll manage on the firewall is also a real pain. My thinking is it would be better and cheaper to Stay with the same host since the dedicated box is fine Get an Amazon AWS account and use their server to manage backups; there are a number of good tools that can be used to automate the process Configure iptables so that I have complete control of the firewall I want to know Is a managed virtual firewall likely to be more secure than me configuring iptables? Whether, in your opinion, it's best to let someone else take care of backups? If, from your experience, there's anything else i'm missing that warrants using managed hosting over a DIY service? I think there is some reluctance to not having managed hosting since a managed host in effect takes responsibility for your server, whereas any hardware or security issues with a server that we manage would mean we are forced to hold our hands up when a client site goes down. That said, I personally don't think a managed host does that much in the day to day running of your server (backups are automatic, OS updates are carried out with ease, etc.).

• Is it possible to use a static IP assigned by my ISP for an offsite web server on a VPS (different ISP)?

  - by NightOwl888

  I have a web server on a Virtual Private Server with a hosting provider. Unfortunately, they are really stingy with IP addresses and I need to run several SSL certificates on my server, so I will need a few more than I have. I have a block of 5 static IP addresses on a business package through a different ISP and I am only using 1 of them for connectivity in the office. What I am wondering is if it is possible to use the 4 unused static IP addresses from this ISP on my VPS, which is hosted by another ISP? The VPS (web server) is running Windows Server 2008 R2 Web Edition. If this can be done, please let me know how to configure it.

• Downloading content greater than 2000 bytes from local network hangs in browser on Windows XP

  - by artplastika

  We have web application that runs under Tomcat in a local network. Our customers experience strange problem using this web application. Let's say Tomcat server runs on host1 and we open webapp URL in browser on host2. Any browser on host 2 starts opening page and downloading of content "hangs" for hours. We've made bunch of experiments and found that any content larger than 2000 bytes makes browser request hang. Tried in Internet Explorer 8, Opera 12, Firefox. At the same time if user opens website from internet, it works. Opening webapp from the same host1 where Tomcat is running works normally. Local network is organized with D-Link DGS-3120-48TC switch. Additional info. During experiments we've noticed XP Tweaker installed on hosts. Network settings from that tool: MTU is manually set to 1500 RWIN = 14600 Support of TCP frames larger than 64 KB is on Time to Live = 32 SACK is on

• Resizing Windows 7 bootcamp partition

  - by Charlie

  I've installed Windows 7 on my Mac using bootcamp but stupidly only allocated it 25gb which isn't enough once I've installed Visual Studio and other stuff. I was able to shrink the Mac partition using whatever tool it is in Mac OS Snow Leopard but it wouldn't let me increase the windows partition so I rebooted into Windows to try it but am still having problems: I coudn't extend it using the disk management tool because the option is greyed out so I tried diskpart.exe but when I use the extend command with my partition selected it says: Virtual Disk Service error: There is not enough usable space for this operation. I've got 19.69gb of unallocated space though so am not sure why I'm having the problem. I don't want to have to wipe my Windows partition, any ideas?

• How can I resolve this error when using net start / stop: "The service name is invalid" ?

  - by JosephStyons

  We have a server that hosts a service (I'll call it "tomato"). Up until now, a client pc has been able to start and stop this service. They just double-click a batch file, and inside that batch file is the command net stop tomato or net start tomato They recently got a new physical computer, and now those same commands fail with the error: C:\>net stop tomato The service name is invalid. More help is available by typing NET HELPMSG 2185. What do I need to do to let the client pc start and stop this service remotely? Edit: I mis-remembered the original commands. They were not using "net start" and "net stop" remotely. They were using sc \\server_name start tomato and sc \\server_name stop tomato And those commands to indeed still work.

• What does an ACPI BIOS configure during boot?

  - by RJSmith92

  When a PC boots with an ACPI BIOS, what does it exactly do? I understand that the point of ACPI is to allow the OS to control hardware resources and power management but before the OS is loaded does ACPI configure just the devices needed to boot and then let the OS configure the rest? If the OS wants to re-asign hardware resources does it store this information in the ACPI tables so that the next time the system is booted it assigns them how the OS wants? The ACPI driver asks the PCI bus driver (Pci.sys) to enumerate devices on it's bus once the OS is loaded, how are these devices configured whilst the PC is booting when it doesn't have other bus drivers? Any help with any of the above questions would be greatly appreciated. Thanks.

• How to check if redis master is OK?

  - by e-satis

  On the documentation, they advice the monitor command. But it has a 50% performance penalty for the whole system, and how should I do that ? Whatching the ouput using SSH until I don't see anything ? Let's say I have 3 servers: 1 with a redis master, 1 with a redis slave, and one with my website querying the redis master. How can I, from my website server, make cleany the decision to fallback to the slave by sending the SLAVEOF NO ONE command ? My first step would be to put some kind of timeout check with a simple ping, just to be sure the server is online. But for redis specifically, I have no clue.

• Need help upgrading MacBookPro3,1 RAM to 4GB.

  - by Fantomas

  My questions are: 1) Where to buy it and what to buy? I have heard that this RAM is generic enough and it does not have to come from Apple. 2) Can I reuse my existing stick(s)? Would I have a single 2GB module, or 2 x 1GB modules? 3) If I have 2GB already, is it a good idea to have one old stick and one new one? Which one is better placed at the top and which one at the bottom? Let me know what questions you have. My computer's info: Hardware Overview: Model Name: MacBook Pro Model Identifier: MacBookPro3,1 Processor Name: Intel Core 2 Duo Processor Speed: 2.4 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache: 4 MB Memory: 2 GB Bus Speed: 800 MHz Boot ROM Version: MBP31.0070.B07 SMC Version (system): 1.16f11

• How to recursively move all files (including hidden) in a subfolder into a parent folder in *nix?

  - by deadprogrammer

  This is a bit of an embarrassing question, but I have to admit that this late in my career I still have questions about the mv command. I frequently have this problem: I need to move all files recursively up one level. Let's say I have folder foo, and a folder bar inside it. Bar has a mess of files and folders, including dot files and folders. How do I move everything in bar to the foo level? If foo is empty, I simply move bar one level above, delete foo and rename bar into foo. Part of the problem is that I can't figure out what mv's wildcard for "everything including dots" is. A part of this question is this - is there an in-depth discussion of the wildcards that cp and mv commands use somewhere (googling this only brings very basic tutorials).

• rsync remote to local automatic backup

  - by Mark Molina

  Because all my work is stored on a remote server I would like to auto backup my server monthly and weekly. My server is running Centos 5.5 and while searching the web I'm found a tool named rsync. I got my first update manually by using this command in terminal: sudo rsync -chavzP --stats USERNAME@IPADDRES: PATH_TO_BACKUP LOCAL_PATH_TO_BACKUP I then prompt my password for that user and bob's my uncle. This backups the necessary files from my remote server to my local device but does somebody know how I can automate this? Like automatic running this script every sunday? EDIT I forgot to mention that I let direct admin backup the files I need and then copy those files from the remote server to a local server.

• Is it possible to have multiple subdomains point to the same Blogger blog?

  - by cclark

  For our application we want to have a status page which is hosted outside of the rest of our infrastructure so in case there are issues in our data center we can post updates for our users and our users will be able to access them. We registered a blog on Blogger and set it up with xyzstatus.blogspot.com and status.xyz.com. Everything seems to work fine. We need to perform some maintenance at our datacenter which will sever all connectivity so we're unable to have a redirect using nginx or apache. We'd like to do this with a short TTL CNAME DNS entry. Ideally www.xyz.com and app.xyz.com could be CNAMEd to status.xyz.com. When I setup the CNAME and go to that URL I get a Google broken robot 404 page. I figure I must need to let Google know it should associate traffic to www.xyz.com and app.xyz.com to the blog served up by status.xyz.com. But I can't see anywhere to do this in Blogger. Does anyone know if this is possible?

• Can certain system-hungry modules be disabled in Ubuntu?

  - by Ole Thomsen Buus

  Hi, Let me add some context: I am currently using Ubuntu 9.10 64-bit (Desktop) on a relatively powerful stationary PC (Intel Core i7 920, 12GB ram). My purpose is highspeed imaging with a pointgrey Grashopper machine-vision camera (for research, PhD project). This camera is capable of 200 fps at full VGA (640x480) resolution. The camera is connected using Firewire (1394b) and the drivers and software from Pointgrey works great. I have developed a console C++ application that can grap a certain number of frames to preallocated memory and after this also save the grapped frames to harddrive. Currently it works fine but sometimes I am observing a few framedrops (1-3). When this happens I reset the experiment and repeat the recording and usually i am lucky the second time with no framedrops (the camera-driver has a internal framecounter that I am using). Question: I usually go to tty1 and use "sudo service gdm stop" to disable the graphical frontend. It seems to release some memory though that is not my main concern. My concern is CPU resources. Are there other system hungry modules that can be disabled temporarily such that the CPU gets less busy on Ubuntu 9.10? At some point in the future I will update to 10.10. Should I perhaps option for the server edition instead? Thanks.

• Google is re-indexing pages after redirecting URLs from HTTP to HTTPS incorrectly

  - by SLIM

  I upgraded my site so that all pages have gone from using HTTP to HTTPS. I didn't consider that Google treats HTTPS pages differently than HTTP. I recreated my sitemap to so that all links now reflect the new HTTPS URLs and let it be for a few days. (Whoops!) Google is now re-indexing all the HTTPS pages. I have about 19k pages on the site, and Google has already indexed about 8k of the new HTTPS pages. The problem is that Google sees all of these as brand new pages when many of them have a long HTTP history. Of course most of you will recognize the problem, I didn't set up a 301 from the old HTTP to the new HTTPS URLs. Is it too late to do this? Should I switch my sitemap back to HTTP URLs and then 301 redirect to the new HTTPS URls? Or should I leave the sitemap as is, and setup 301 redirects anyway... I'm not even sure if Google is trying to reach the HTTP site anymore. Currently the site is doing 303 redirects (from HTTP to HTTPS), although I haven't figured out why yet.

• Outlook 2007 Script that sends new form email when a message is dragged and dropped into a folder

  - by Mark

  Is it possible to write a script that will allow Outlook to automatically send out a new email to a distribution list when you drag and drop and previously opened email into a specified folder? The rules only let you apply them to received and sent messages. They do not allow you to apply it to anything that is dragged and dropped after being opened. It baffles me that Novell Groupwise had this functionality but Outlook 2007 does not. If someone can assist me in writing a script/macro to provided this functionality, it would be greatly appreciated. Thank you.

• Running a webserver behind a firewall, is it secure?

  - by i.am.intern

  Currently we have a Linux-based firewall which NAT-ing our public IP address to give internet access to our staff's PCs and a Windows Server 2003 for internal filesharing. I want to host Redmine/SVN (a bugtracker) internally behind this firewall using a Linux server. This webserver will be accessed by our clients externally so they can post bug reports. This means that I have to open port 80 & 22 at the firewall to give access to the webserver and me to SSH it from home. However, let's say I'm using password-based SSH for the webserver and somebody cracked it. Does that mean the cracker could ping and access other servers and PCs in the network?

• Remote file copy util (like rsync) but that will take account of data already copied (in this sessio

  - by Rory McCann

  Let's say I have a directory with 2 files, both are identical and quite large (e.g. 2GB ea.) I want to rsync that directory to a remote host. As I understand it (and I could be wrong), rsync calculates checksums of files. Surely if it sees 2 files with the same checksum it can just copy the first file, then do a local copy on the remote host for the 2nd file? That would make it faster, no? On a similar note, doesn't rsync hash all the remote files before copying? If it saw a different file with the same hash as a file that was to transfered, it could do a local copy on the remote host. Does rsync support this sort of thing? Is there some way to turn it on? Is there a tool similar to rsync that will do this sort of 'hash based' local copies?

• Which repo and version of Percona for Natty?

  - by thefella

  I'm wanting to drop in Percona instead of MySQL (5.1) on my Natty ubuntu server. I've added the keys and the repos. I've added a natty repo, even though it's not supposed to exist and it seems to be fine. The problem is when I go an apt-get install percona-server-server, it tells me that it depends on percona-server-server-5.5 and won't be installed. Should I just install 5.5 (over the top of mysql 5.1) or do I need to install percona 5.1? Or do I need to pick a different repo and let it decide?

• Groovy Grapes in NetBeans IDE

  - by Geertjan

  The start of Groovy Grapes support in NetBeans IDE. Below you see a pure Groovy project, with the Groovy JAR and the Ivy JAR automatically on its classpath. There's also a Groovy script that makes use of a @Grab annotation. In the bottom left, in the Services window, you also see a Grape Repository browser, i.e., showing you the JARs that are currently in ".groovy/grapes". Click the images below to get a better look at them. Next, you see what happens when the project is run. The @Grab annotation automatically starts downloading the JARs that are needed and puts them into the ".groovy/grapes" folder. However, the "no suitable classloader found for grab" error message (which Google shows is a problem for lots of developers) prevents the application from running successfully: The final screenshot shows that I've put the JARs that I need onto the classpath of the project. I did that manually, hoping to learn from the NetBeans Maven project or the NetBeans Gradle project how to do that automatically. Also note that the @Grab annotation has been commented out. Now the error message about the classloader is avoided and the project runs. What needs to happen for Groovy Grapes support to be complete in NetBeans IDE: Figure out how to add the downloaded JARs to the project classpath automatically. Fix the refresh problem in the Grape Repository browser, i.e., right now the refresh doesn't happen automatically yet. Hopefully find a way to get around the grab classloader problem, i.e., it's not ideal that one needs to comment out the annotation. Let the user specify a different Grape repository, i.e., right now ".groovy/grapes" is assumed, but the user should be able to point the repository browser to something different. Maybe there should be support for multiple Grape repositories? Comments/feedback/help is welcome.

• Thunderbird 3.0 refuses to start on Mac OS X?

  - by jtimberman

  I just downloaded Thunderbird 3.0 on my Macbook Pro running Leopard, and installed it in /Applications. When I attempt to start it, the icon opens on the Dock as normal, but I get the following dialog. I don't have a ~/Library/Application Support/Thunderbird directory at all, let alone a .parentlock file. While I didn't expect it to help, I did reboot my system. And sign out and back in. And close all programs besides Thunderbird. Earlier versions of Thunderbird have worked just fine.
