People keep saying that Entity Framework is simple to learn. Simple? Well, finally, we're going to be forced to agree, thanks to James Johnson's new series on learning EF the hands-on way.
On our windows 2003 domain, with XP clients, we have started seeing routes appearing in the routing tables on both the servers and the clients. The route is a /32 for another computer on the domain. The route gets added when one windows computer connects to another computer and needs to authenticate.
For example, if computer A with ip 10.0.1.5/24 browses the c: drive of computer B with ip 10.0.2.5/24, a static route will get added on computer B like so:
dest netmask gateway interface
10.0.1.5 255.255.255.255 10.0.2.1 10.0.2.5
This also happens on windows authenticated SQL server connections. It does not happen when computers A and B are on the same subnet.
None of the servers have RIP or any other routing protocols enabled, and there are no batch files etc setting routes automatically.
There is another windows domain that we manage with a near identical configuration that is not exhibiting this behaviour. The only difference with this domain is that it is not up to date with its patches.
Is this meant to be happening? Has anyone else seen this? Why is it needed when I have perfectly good default gateways set on all the computers on the domain?!

I know that domain names are constantly changing, and I know there are a lot of them, but there is clearly a region of the domain name space which is stable. How would I go about getting a list, even a very big one?
Such a thing must logically exist, even if it is in a distributed form, because the web's DNS servers resolve names to IP addresses. So in theory if I could poll all the DNS servers in the world at a moment in time I would have the complete list of mapped names. Is there a practical way of doing that?
As an aside, does anyone have any good estimates of how many domain names exist at the moment?
Perhaps I just don't understand how the whole CLASSPATH environment variable works when trying to find .jar files on your system. I thought if you specified it, you could launch .jar files with java in much the same way that you can launch executables that are on your path.
I have an executable java archive (.jar file) on my system, that I stuck in /usr/local/bin/gatk/. I added this to my CLASSPATH via:
export CLASSPATH=/usr/local/bin/gatk/GenomeAnalysisTK.jar
I thought this would make the .jar file visible to my JVM. When I try to invoke it with
java -jar GenomeAnalysisTK.jar
#Error: Unable to access jarfile .gatk/GenomeAnalysisTK.jar
I can invoke it setting the absolute path, e.g.
java -jar /usr/local/bin/gatk/GenomeAnalysisTK.jar, however I'd rather not type the full path each time. I have read many of the linked tutorials but somehow I don't seem to be getting this right and I can't understand what I am doing wrong.
I have FTP access to an Apache server on linux to upload files so that they can be downloadable from the web.
I recently was granted SSH access for extra permissions and figured that it would be quicker to download the files directly to the server, instead of downloading them to my machine then FTPing to the server.
When I downloaded a file using SSH to the server, and then placed it in the public_html directory, it was not visible from the web. The permissions (from SSH and the FTP client) were the same as all the other files that are visible, but it was not visible in the directory listing, and if I tried to type in the filename into my browser I would get a 403 error.
Obviously, when I FTP a file to the server something else happens that makes it web visible, that I am not currently privy to.
What am I missing that is causing the file to be invisible from the web?
I'm having an issue. Windows XP, running the latest Chrome 23 build. I'm using Flash 11.5 built into Chrome (Pepper Flash). It runs horribly. Chrome 22 did not have this issue as far as I recall. What a shame.
YouTube videos stutter badly and after a while, they begin to lag and lose sync with the video. I disabled Pepper Flash and tested HTML5 video in YouTube and it was smooth as glass. Additionally, certain Flash based games are almost unusable now. The plug-in is using 100% CPU and it lags horribly in these games. Google/Adobe, please fix this. I shouldn't have to disable the built-in Flash plug-in (with added sandboxing security) and use regular Flash to resolve this. Short of waiting for an update to Chrome, does anyone have a better solution to fixing this? I am all ears.
I've produced a website for a client One Single Menu using JBoss and hosted it on Rackspace Cloud Servers running Ubuntu's Maverick Meerkat. Following advice, I esablished some iptables rule to protect jboss:
iptables -I INPUT 1 -i lo -j ACCEPT
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A INPUT -p tcp --dport 22 -j ACCEPT
iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080
iptables -I INPUT -p tcp --dport 8080 -j ACCEPT
iptables -t nat -A OUTPUT -o lo -p tcp --dport 80 -j REDIRECT --to-port 8080
iptables -A INPUT -j DROP
Now, several versions of IE on several computers on at least two different ISPs cannot access the onesinglemenu.com. Curl from within the datacenter, Firefox, and Safari on the same ISPs can all access the server fine. I even tried IE and Firefox on the same computer and IE failed but Firefox worked.
The error behaviour is that IE hangs on connecting without reporting an error, even after a minute or so. No page is displayed at all.
I find it quite odd that I'm having a browser specific connection issue, but it appears to be the case. Help!
I'm running Windows XP Professional on a PC which is less than a year old. About 3 months ago I got an error on boot saying windows could not find my profile. At this point it created a temp one. On this occasion I copied the temp data back into my existing profile and carried on using it. After another month it died again and, once again set me up a temp user. Each time this happens I lose everything related to my profile (desktop, start menu, etc). I ran checks on the hard disk and these suggested nothing was wrong so this seems a software issue not a disk problem.
On the advice of my computer manufacturer I am now considering reinstalling Windows but just wanted to check if there's any other ideas for things I might be able to try. Any suggestions for what could be causing the problem would also be gladly appreciated.
I have a single ethernet run at home that I just added. I have a cable tester that tests for pin/pair crossover or miswired pins. The entire line tests green (all 4 LEDs light up green on the tester) but I can't get any PC to connect through the link. No link light on the ethernet connection.
Any simple tests/fixes, or do I rip out the wall sockets and do it again?

Hi All,
Is it possible to mount the VHD files created by the Windows Server 2008 backup utility onto a Windows 7 (release) client?
Following an array failure I was very worried that there was a problem with both the backup sets on different USB drives as attaching the VHD to a Win 7 box did not show the expected structure (instead they behaved like unformatted disk space).
Subsequently, I've attached the backup drive to a 2008r2 machine that I'd intended to be the replacement and the backup set can be browsed without issue (seemingly). When the new disks arrive I'll go through the recovery process and see where we are, but it looks promising so far.
Is it simply the case that you can't take server created VHD's and mount them on desktop machines?
(Rather than hyper-ventilating at the thought of years of lost photos and email, I'm now just mildly curious)
Edit:One thing that has confused things is that the backup utility on Win7 is more restrictive about restoring from external devices than the equivilent on 2008r2. With r2, I can restore files 'from another server' and browse to external storage. Win7 only allows the back to be located on a network share. Once my box of new disks arrive and I've got something to restore onto, I'll move the smaller of the backup VHDs onto network storage reachable by Win7 and see if the VHD is readable.
I haven't read up on the VHD process used by the backup app - I'm assuming it's a base VHD and differencing files used for incremental backups and that the restore app understands this.
Finally: In retrospect the question should have been, 'can I restore a 2008r2 backup set via a Win 7 client'
Thanks
I'm currently in possession of an eMac G4 running OS X 10.4. I went to install some software, and found I didn't actually have the password. No one seems to know it, and it's not written down anywhere. These were purchased by the school many years ago and are not really maintained, since people just used Garageband mostly.
I went to look for the restore disk, and its nowhere to be found. How can I reset the password without a disk?
Is there a way I can determine if hardware virtualisation is enabled in Karmic? I know my processor is capable of it (from knowing it's an AMD Athlon 64 x2 & via something coming out when I type egrep '(vmx|svm)' --color=always /proc/cpuinfo), but I can't tell if I need to flash my bios to enable it.
In thunderbird 3, I can open new tabs if I middle-click, but the behaviour I want is for left-click to open a new tab if there is not already a folder open for a given tab; or to switch to the tab displaying that folder if there is.
Is there a configuration setting or addon which will make thunderbird behave like that?
Hi, I've been reading up on how to tune SQL Server 2005 for a machine in a test environment. I came across this article on technet which suggests how to configure "server tasking" and says I should refer to the Windows 2003 docs for more info.
I have googled Windows 2003 "server tasking" (with and without the quotes) but all I can find is more similar articles on SQL server telling me that it should be configured, not how/where you do it.
I know I'm probably searching for the wrong thing - can someone please tell me how to configure it in Windows or SQL server, whichever it is?
We have a Dell Power-edge T110 server, with either a PERC S100 or S300 raid controller (I suspect S100), and 2 x 500GB SATA hard discs.
These discs are running in RAID-1 configuration, (either 1 or 2 virtual discs), and on top of this, we have the C and D drives.
As we are running low on disc space, we are looking at dropping the RAID to get some disc space back.
Is it possible to split the discs back into 2 seperate hards discs that the OS can see, without losing all the data on the drives? Even better, would it be possible to split the D: drive, leaving the OS C: drive in RAID1 configuration?
Do any hosting companies offer SQL Server 2008 Web edition in a hosting plan.
GoDaddy for instance offers Standard/Enterprise editions which raise the price by $200 or so a month.
I've tried a few hosting companies and can't find the web edition available. Why not?
The web edition is supposed to be only $15/month - but I was hoping to be able to get this pricing through a dedicated server and not have to go off and separately get the licensing. I don't even know if its possible to buy just one copy!?
I'm looking for a, preferably free, NTP Server for Windows Server 2003/2008. We have already tried the built in Windows Time Server, but our tests did show that it is not very accurate, we see time differences up to 500ms. The max time difference we can allow for our application is ~100ms.
Now we have already used the Meinberg NTPd for Windows. It works great except we have one big issue with it: If there is a network connection problem between the client and server, the ntp server is in a panic state It won't give the client a new time until we restart the ntp service. This is a big issue which has caused us some trouble. It was working fine for months until there was a network problem we didn't notice, we only noticed it after a week when the time difference was already 30 sec. on the clients.
So please suggest some alternative NTP Server for windows. I did Google but I get a lot of unrelated search results.
Edit:
So far the ntpd windows version was very accurate and I'd like to stick with it. The only problem is the "panic state" after a network disconnect. Maybe some knows here what the cause of this is and how to fix it.
Also, I forgot to mention that we have a server/client setup like this:
Server1 -- Server2 -- Server3 -- Client1
-- Client2
-- Client3
So Server2 gets its time from Server1, Server3 gets its time from Server2, and the Clients get their time from Server3. Also, there are clients connected directly to Server2. It is important that all Servers and Clients have the exact same time (within ~100ms)
Now there was a network problem with Server3 and its clients. The servers run the ntpd port for Windows, which acts as NTP server and client. The clients have Dimension4 as NTP client. After the network problem, the error message in D4 was something like this (out the top of my head, don't have the exact error message):
Server response: The server is in a panic state (could not sync clock)
I read through the ntpd docs, and the only mention of "panic" is when the time difference is 10000 seconds which will cause to exit the ntpd server but this was not the case. Also there is a "-g" command line switch to disable the panic exit, but it is already set by default.
Any ideas what could cause the panic state and how to get rid of it next time?
Hi
I have a very simple question. I wanna have a diagram with the
following table
Apple 30 40 50
Pears 200 300 400
Bananas 10 20 30
The weird thing, when I try to draw a bar diagram the order of the bars
change. So Excel draws me first the Bananas, the the pears and finally the apple
bar... Is there anyway to tell Excel 2003 that it keeps the order?
Thank you very much

My key requirements are:
I don't want to worry/ know/ care about the server/ infrastructure
Secure/ up to date software/ os
Good monitoring
Automatic scalability
SLA
I apologise for the length of the question.
In short all I want to do is i). create vhost, ii). create db iii). install app/ site iv). relax.
Thanks.
Edit:
I include the Matrix vhost because that is the only complication that I cannot really do via a .htaccess file.
Hi all,
I created a user account in postfix in the form: [email protected].
When I receive emails from that account, in gmail, for example, the senders name is "editor", but I want to show something like "Editor Surname".
Any idea of how to it? Thanks in advance!
