• View Public Key in Domain Key for a Domain

  - by Josh

  Using Jeff's blog post I'm creating domain keys for my account. I wanted to verify the setup using Get or Host command with Bind for Windows but I'm lost one of the commands. I can see view the _domainkey. txt file with this command: host -t txt _domainkey.stackoverflow.com but I'm at a loss at how I'd find the selector record. Jeff points out it can be anything before the before the period in "._domainkey.domain.com" but how would I list all records if I didn't know the exact query name? Is there a wildcard I could use to view all TXT or all records under this section?

• How can I sort du -h output by size

  - by Tom Feiner

  I need to get a list of human readable du output. However, du does not have a "sort by size" option, and piping to "sort" doesn't work with the human readable flag. For example, running: du | sort -n -r Outputs a sorted disk usage by size (descending): du |sort -n -r 65108 . 61508 ./dir3 2056 ./dir4 1032 ./dir1 508 ./dir2 However, running it with the human readable flag, does not sort properly: du -h | sort -n -r 508K ./dir2 64M . 61M ./dir3 2.1M ./dir4 1.1M ./dir1 Does anyone know of a way to sort du -h by size?

• How to install (old) packages for Ubuntu 9.04?

  - by wchrisjohnson

  Based on some excellent feedback by Mark here (http://serverfault.com/questions/285598/should-i-clone-a-physical-server-to-create-a-vm-for-a-staging-server), today I was able to use the vmware converter to clone my production server for a staging server. However the nic won't come up no matter what I do. I attempted to inistall vmware tools, as I suspect that the fact that it is not installed might prevent the nic from working. (I have the nic set as a vmxnet3 card in the vm settings). The install failed because there were several dependencies missing as well as the Linux headers. Given that Ubuntu 9.04 has been EOL'd, the packages I need to install to get the vmware tools to install are no longer available. I doubt the ubuntu 9.04 install CD has the packages on it. What are my options? I'd rather not upgrade the version of Ubuntu yet, as the point of the vm right now is to maintain parity with the production server. Might I have better luck resetting the driver to use vmxnet2 instead of the vmxnet3? Thanks in advance! Chris

  - by Zhenyu Li

  I just installed powerdns, and I added the record example.com A 120 1.2.3.4 and I used dig to see if it works, and it works. dig @localhost example.com and it will show the correct ip address : 1.2.3.4 My question is how to use this dns server in the public, so that my domain example.com to be dig without the @localhost?

• htaccess for subdomain help

  Usually I just use the online tools for url mod_rewrite rules but this just wouldn't work.

• Have an Input/output error when connecting to a server via ssh

  - by Shehzad009

  Hello I seem to be having a problem while connecting to a Ubuntu Server while connecting via ssh. When I login, I get this error. Could not chdir to home directory /home/username: Input/output error It seems like my home folder is corrupt or something. I cannot ls in the home folder directory, and in my usename directory, I can't cd into this. As root I cannot ls in the home directory as well or in any directory in Home. I notice as well when I save in vim or quit, it get this error at the bottom of the page E138: Cannot write viminfo file /home/root/.viminfo! Any ideas?

• Debug.Assert has locked / hung my IIS6 site - how do I bring it back?

  - by George

  I'm running some C# / ASP.net code on an IIS6 server. The code has triggered a "Debug.Assert", and now my IIS6 server is not responding for this site — at least that's what I strongly suspect given that this was the cause the last time this happened. How do I bring the site back up? Stopping and then starting the site doesn't bring it back — I continue getting timeouts from the proxy, which I think is caused by the site itself crashing. How do I disable Debug.Assert permanently in production? Do I just edit the web.config: <compilation defaultLanguage="c#" debug="false"... — is there anything else I need to do?

• phpmyadmin login redirect fails with custom ssl port

  - by baraboom

  The server is running Ubuntu 10.10, Apache 2.2.16, PHP 5.3.3-1ubuntu9.3, phpMyAdmin 3.3.7deb5build0.10.10.1. Since this same server is also running Zimbra on port 443, I've configured apache to serve SSL on port 81. So far, I have one CMS script running on this virtual host successfully. However, when I access /phpmyadmin (set up with the default alias) on my custom ssl port and submit the login form, I am redirected to http://vhost.domain.com:81/index.php?TOKEN=foo (note the http:// instead of the https:// that the login url was using). This generates an Error 400 Bad Request complaining about "speaking plain HTTP to an SSL-enabled server port." I can then manually change the http:// to https:// in the URL and use phpmyadmin as expected. I was annoyed enough to spend an hour trying to fix it and now even more annoyed that I cannot figure it out. I've tried various things, including: Adding $cfg['PmaAbsoluteUri'] = 'https://vhost.domain.com:81/phpmyadmin/'; to the /usr/share/phpmyadmin/config.inc.php file but this did not correct the problem (even though /usr/share/phpmyadmin/libraries/auth/cookie.auth.lib.php looks like it should honor it and use it as the redirect). Adding $cfg['ForceSSL'] = 1; to the same config.inc.php but then apache spirals into an infinite redirect. Adding a rewrite rule to the vhost-ssl conf file in apache but I was unable to figure out the condition to use when http:// was present along with the correct ssl port of :81. Lots of googling. Here are the relevant Apache configuration pieces: /etc/apache2/ports.conf <IfModule mod_ssl.c> NameVirtualHost *:81 Listen 81 </IfModule> /etc/apache2/sites-enabled/vhost-nonssl <VirtualHost *:80> ServerAdmin webmaster@localhost ServerName vhost.domain.com DocumentRoot /home/xxx/sites/vhost/html RewriteEngine On RewriteCond %{HTTPS} off RewriteRule (.*) https://%{HTTP_HOST}:81%{REQUEST_URI} </Virtualhost> /etc/apache2/sites-enabled/vhost-ssl <VirtualHost *:81> ServerAdmin webmaster@localhost ServerName vhost.domain.com DocumentRoot /home/xxx/sites/vhost/html <Directory /> Options FollowSymLinks AllowOverride None AuthType Basic AuthName "Restricted Vhost" AuthUserFile /home/xxx/sites/vhost/.users Require valid-user </Directory> <Directory /home/xxx/sites/vhost/html/> Options -Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> </VirtualHost> /etc/apache2/conf.d/phpmyadmin.conf Alias /phpmyadmin /usr/share/phpmyadmin (The rest of the default .conf truncated.) Everything in the apache config seems to work ok - the rewrite from non-ssl to ssl, the http authentication, the problem only happens when I am submitting the login form for phpmyadmin from https://vhost.domain.com:81/index.php. Other configs: The phpmyadmin config is completely default and the php.ini has only had some minor changes to memory and timeout limits. These seem to work fine, as mentioned, another php script runs with no problem and phpmyadmin works great once I manually enter in the correct schema after login. I'm looking for either a bandaid I can add to save me the trouble of manually entering in the https:// after login, a real fix that will make phpmyadmin behave as I think it should or some greater understanding of why my desired config is not possible.

• How should I deploy my JVM-based web application on ubuntu?

  - by Pieter Breed

  I've developed a web application using clojure/compojure (JVM based) and while developing I tested it using embedded jetty that runs on 0.0.0.0:8080. I would now like to deploy it to run on port 80 on ubuntu. I do dynamic virtual hosting, so any request for any host that arrives on port 80 should be handled by my application. The issues that worries me are: I can still run it embedded but I'm worried about running my app as root (needed for binding to port 80). I'm not sure if I can 'give up root' when in the JVM. Do I need to be concerned by this? besides, serving web applications is a known problem and I should be using known solutions for this (jetty or tomcat) but especially tomcat seems very heavy weight. Besides, I only have one application that listens to /* and does routing internally. (with compojure/ring). What I'm trying to say with this is that tomcat by default assigns WARs to subfolders which I don't want. So basically what I need is some very safe way of binding to port 80 on ubuntu that can with minimal interference send all requests to my app. Any ideas?

• Nginx Rewrite rules for clean URLs

  - by Sujay

  I want to write nginx rewrite rules for clean URLs. Everytime the user hits http://domain.com/abc/12/16/abc-def-ghi I need to execute domain.com/abc.php?a=12&b=16&c=abc-def-ghi. Now my regex is right as per rubular: ^\/abc\/(\d+)\/(\d+)\/(\w+\S+)$ http://rubular.com/regexes/11063 and rule is if (!-e $request_filename) { rewrite ^\/abc\/(\d+)\/(\d+)\/(\w+\S+)$ abc.php?a=$1&b=$2&c=$3 last; } But it is giving "No input File specified". I cant find what the problem is?

• Does OneNote have palm rejection or a hand rest spot?

  - by Richard DesLonde

  I just bought an Acer Iconia W500. I really wanted to use it for taking notes and having all the amenities of a full blown computer without the size. Using OneNote to take notes, I notice I can't rest my hand on the screen. I have read some about this and it seems the very best solution is to get a tablet with active digitizer technology, but there aren't too many with this and it is expensive. So barring that, is there any way I can rest my hand on the tablet screen while taking notes in OneNote? Or am I relegated to hovering my hand over the screen while I write notes? Does OneNote have a palm rest area or some sort of palm rejection?

• How anti-virus on the host machne affects performance of virtual machines?

  - by Ladislav Mrnka

  I'm diagnosing some issue with Oracle virtual box where virtual machine sometimes perform terribly slow (much slower then notebook with worse configuration): Notebook i7 (2 cores with HT = 4 logical CPUs), 4GB RAM, 5400 rpm disk, Win 7 64bit Virtual machine (Oracle Virtual Box) Host: i7 (4 cores with HT = 8 logical CPUs, 12 GB RAM, system runs from SSD, virtual machine from 7200 rpm disk, Win 7 64bit) Virtual machine: 4 cores assigned, 8 GB RAM assigned, Win 2008 R2 Enterprise (64 bit) Virtual machine uses bridge to separate network interface (machine has two) VPN for network communication No other virtual machine runs on the host Host has installed ESET Smart Security All SW is updated with last version. My question is if anti-virus on the host machine can somehow affect performance of the virtual machine and if so how can I turn it off without turning the anti-virus itself?

• Finding, which web component is causing problems during page loading

  - by Juhele

  I am using windows version of Firefox 5.0 and last few days I found that on one website (similar focus as stackexchange but in Czech), is something wrong as my browser loads it very slowly (while the connection is ok and never had problems with it). There is also another guy trying to solve the almost the same problem, but no help yet. So I would ask, whether there is some Firefox plugin showing which page components are loading and which could help me to find out the problem. I am writing from office pc so we have blocked all the social networks like FB, Twitter etc. and I also use Adblock Plus - however, deactivating it does not have any effect on it. thanks

• Create samba shortcut from command line

  - by neurolysis

  I'm currently wanting to deploy a setup to around 300 Macs. I have most of it scripted, but I'm having trouble creating a working alias to a samba share from the command line. I tried copying it from one Mac to another, but it loses its status as an alias, and instead OSX opens it in TextEdit. From a hexdump, it also looks like it has machine-specific information. So, say I wanted to create an alias to 'smb://server/share' on the desktop from the command line, how would I do that? I have also tried a tell in AppleScript, but it complained about the syntax (specifically, too many slashes, seemingly taking about smb://). Thanks.

• Firefox extension to save tabs?

  - by emzero

  I'm looking for some Firefox (4 or 5) extension to save a group of tabs (better if can be done directly in Panorama view). What I mean by "Save tabs" is not to restore them when Firefox starts. I always have the browser opened and a LOT of tabs (work and personal life related) eating my RAM. So when I'm not working, I would want a way to save those tabs but keep them closed while I still use Firefox. So when I have to start working again, I will restore that saved tabs back again. I know I could use something like Read It Later, but I really need a way to say "hey, save this group of tabs and close them". RIL makes me do it per tab, which is annoying since I'm used to have A LOT.

• Is there any *good* HTML-mode for emacs?

  - by Carson Myers

  I love emacs, and I want to do my web-programming work in it, but I can't find a way to get it to edit HTML properly. I mean it's seriously awful. It will do HTML fine, but not PHP, javascript, etc. I tried getting html-helper-mode... I downloaded it, put it in /usr/local/share/emacs/site-lisp, and added it to my .emacs file: (autoload 'html-helper-mode "html-helper-mode" "Yay HTML" t) (setq auto-mode-alist (cons '("\\.html$" . html-helper-mode) auto-mode-alist)) copied and pasted from some site (I don't know elisp). it just, doesn't highlight anything at all. I tried downloading a whole bunch of modes and using some other mode to string them together, to no avail. Emacs is so great in every other way--why can't it do the simple task of editing web pages? I mean, it's a pretty standard thing to do for editors these days. So, does anyone know how to do this?

• Where does truecrypt store the backup volume header?

  - by happygolucky

  When using WDE, where does (if anywhere) truecrypt store a backup volume header? As i know there is always a backup header for regular truecrypt volumes, however i am not sure if this applies when system encryption is used. Because if i damage the volume header in track 0, my password won't boot my system anymore. So there is no backup header on the drive? I read somewhere on a forum that truecrypt might have a backup header relative to some position from the END of the HDD, however this doesn't make sense as it could easily be wiped over by programs running in Windows. And how would truecrypt know where this backup is anyway?

• Set proper rights for sshfs mountpoint so it can be shared with samba

  - by CS01

  I have a domain hoster that provides access via SSH. My platforms are: Gentoo 2.6.36-r5 Windows (XP/Vista/7) I work on my Windows, I use Gentoo to do all the magic Windows can't do. Therefore I use sshfs to mount the remote public directory for my domain to /mnt/mydomain.com. Authentication is done via keys, so lazy me don't have to type in my password every now and then. Since I do my coding on Windows, and I don't want to upload/download the changed files all the time, I want to access this /mnt/mydomain.com via a samba share. So I shared /mnt in samba, all mounts except mydomain.com is listed on my Windows Explorer. My theories are: sshfs does not set the mountpoint uid/gid to something that samba expects samba does not know that it has to include the uid/gid that /mnt/mydomain.com has been set. All above is wrong, and I don't know. Here are configs and output from console, need anything else just let me know. Also no errors or warnings that I take notice of being relevant to this issue, but I might be wrong. gentoo ~ # ls -lah /mnt total 20K drwxr-xr-x 9 root root 4.0K Mar 26 16:15 . drwxr-xr-x 18 root root 4.0K Mar 26 2011 .. -rw-r--r-- 1 root root 0 Feb 1 16:12 .keep drwxr-xr-x 1 root root 0 Mar 18 12:09 buffer drwxr-s--x 1 68591 68591 4.0K Feb 16 15:43 mydomain.com drwx------ 2 root root 4.0K Feb 1 16:12 cdrom drwx------ 2 root root 4.0K Feb 1 16:12 floppy drwxr-xr-x 1 root root 0 Sep 1 2009 services drwxr-xr-x 1 root root 0 Feb 10 15:08 www /etc/samba/smb.conf [mnt] comment = Mount points writable = yes writeable = yes browseable = yes browsable = yes path = /mnt /etc/fstab sshfs#[email protected]:/home/to/pub/dir/ /mnt/mydomain.com/ fuse comment=sshfs,noauto,users,exec,uid=0,gid=0,allow_other,reconnect,follow_symlinks,transform_symlinks,idmap=none,SSHOPT=HostBasedAuthentication 0 0 For an easier read: [email protected] /home/to/pub/dir/ /mnt/mydomain.com/ options: comment=sshfs noauto users exec uid=0 gid=0 allow_other reconnect follow_symlinks transform_symlinks idmap=none SSHOPT=HostBasedAuthentication Help!

  I use a lot word with in outline view. In that view it is not possible to see images (while it was possible in 2007).

I tried to read all the options, but I didn't find a matching checkbox. NOTE FOR BOUNTY: I started a bounty because this problem is really annoying for me. Please read the existing answer(s) and comment(s) before answering. Thanks.

• Networking stopped working on Ubuntu

  - by 1337Rooster

  I installed Ubuntu 10.04 through the Wubi installer (Funny, I installed it today and thought I would have gotten 10.10). I had a network connection and everything was working fine. I rebooted my coumputer a couple of times and then suddenly, I could not connect to the network and when I click the wireless/networking icon it says "Networking Disabled". I reinstalled Ubuntu and the problem went away. After a few reboots the problem returned. I have tried restarting to see if it would come back as well as a few other things listed below. Any other suggestions would be appreciated. Tried to restart networking via /etc/init.d/networking: amato@ubuntu:~$ sudo /etc/init.d/networking restart * Reconfiguring network interfaces... Ignoring unknown interface eth0=eth0. [ OK ] Tried to stop and start it: amato@ubuntu:~$ sudo /etc/init.d/networking stop * Deconfiguring network interfaces... [ OK ] amato@ubuntu:~$ amato@ubuntu:~$ sudo /etc/init.d/networking start Rather than invoking init scripts through /etc/init.d, use the service(8) utility, e.g. service networking start Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the start(8) utility, e.g. start networking networking stop/waiting Tried start networking: amato@ubuntu:~$ start networking start: Rejected send message, 1 matched rules; type="method_call", sender=":1.58" (uid=1000 pid=2241 comm="start) interface="com.ubuntu.Upstart0_6.Job" member="Start" error name="(unset)" requested_reply=0 destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init")) amato@ubuntu:~$ sudo start networking networking stop/waiting Tried service networking restart: amato@ubuntu:~$ service networking restart restart: Rejected send message, 1 matched rules; type="method_call", sender=":1.60" (uid=1000 pid=2248 comm="restart) interface="com.ubuntu.Upstart0_6.Job" member="Restart" error name="(unset)" requested_reply=0 destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init")) amato@ubuntu:~$ sudo service networking restart restart: Unknown instance: Here are the contents of my /etc/network/interfaces. auto lo iface lo inet loopback I even tried to modify it to this (based on something I read, online, not sure if I was doing the right thing here).

• Ubuntu xrandr rotate issue

  - by user83544

  I've just bought a second monitor for my PC which happens to be a pivot monitor. I've already read lots of forums related to my problem but haven't come across a solution - I have the same symptoms as dozens of posts but no matter whatever I try it just doesn't work. I've already changed the xorg.conf file and added in the device section just under Driver "nvidia" the following for my second monitor: Option "RandRRotation" "on" When I save and reboot I try to rotate my screen with the nvidia X server settings by choosing the second monitor and clicking either "left" or "right" for the rotation. It immediately exits the nvidia settings window and does nothing. I tried within the terminal by typing: xrandr -o right I get the following error: X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 154 (RANDR) Minor opcode of failed request: 2 (RRSetScreenConfig) Serial number of failed request: 14 Current serial number in output stream: 14 I actually manage to rotate it with Option "Rotate" "CCW" instead of "RandRRotation". The problem with this solution is that you get the second monitor in the right position, but any window you open on that screen is practically unchangeable. You can't change the size nor move it, making it useless for reading PDFs, which is the main reason why I bought this second screen to help me write my thesis. Any help is really appreciated. sudo lshw -c video hiram@hiram-linux:~$ sudo lshw -c video *-display description: VGA compatible controller product: nVidia Corporation vendor: nVidia Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nvidia latency=0 resources: irq:16 memory:f8000000-f9ffffff memory:d8000000-dfffffff memory:d4000000-d7ffffff ioport:dc00(size=12 memory:fbd80000-fbdfffff

• Data Recovery needed with a Sector Zero problem on a HDD

  - by Jay Robins

  Left my computer (running XP) copying files to an external drive. Came back a few hours later, and the laptop was pretty hot and had frozen (Ironic aint it). Forced a reboot, and the laptop HDD hasnt worked since. Set it up in an external enclosure, but XP cant mount the HDD to a drive letter, but is able to recognize the manufacturer and drive size (Hitachi-320GB). No noise or rattling when the drive is spinning, but I cant get anything off of it, since i cant mount it, or see much of anything. Computer repair shop ran some software tests and says it came back with a "Zero Sector bad" message, and need to send it to a professional data recovery service. Any other options or ideas, before I have to spend thousands of dollars to recover my data? Any help would be GREATLY appreciated!!! I'm desperate and a poor student! Thanks in Advance, -Jay

• The Best How-To Geek Articles for June 2011

  - by Asian Angel

  June has been a busy month here at How-To Geek where we covered topics like cleaning keyboards, what to do when your e-mail has been compromised, creating high resolution Windows 7 icons, and more. Join us as we look back at the most popular articles from this past month. Note: Articles are listed as #10 through #1. What You Said: How Do You Keep Notes? Note taking applications have grown increasingly sophisticated. Historically, when people took notes on a computer they simply used the word processor or text editor installed on it and left it at that—mostly because there were few widely available alternatives. While many people still use simple txt files for their note taking needs an entire ecosystem of note taking apps exists now—thanks, in large part, to the rise of widespread internet access and easy synchronization.How To Encrypt Your Cloud-Based Drive with BoxcryptorHTG Explains: Photography with Film-Based CamerasHow to Clean Your Dirty Smartphone (Without Breaking Something)

• SQL SERVER – Interview Questions and Answers – Frequently Asked Questions – Introduction – Day 1 of 31

  - by pinaldave

  List of all the Interview Questions and Answers Series blogs Posts covering interview questions and answers always make for interesting reading.  Some people like the subject for their helpful hints and thought provoking subject, and others dislike these posts because they feel it is nothing more than cheating.  I’d like to discuss the pros and cons of a Question and Answer format here. Interview Questions and Answers are Helpful Just like blog posts, books, and articles, interview Question and Answer discussions are learning material.  The popular Dummy’s books or Idiots Guides are not only for “dummies,” but can help everyone relearn the fundamentals.  Question and Answer discussions can serve the same purpose.  You could call this SQL Server Fundamentals or SQL Server 101. I have administrated hundreds of interviews during my career and I have noticed that sometimes an interviewee with several years of experience lacks an understanding of the fundamentals.  These individuals have been in the industry for so long, usually working on a very specific project, that the ABCs of the business have slipped their mind. Or, when a college graduate is looking to get into the industry, he is not expected to have experience since he is just graduated. However, the new grad is expected to have an understanding of fundamentals and theory.  Sometimes after the stress of final exams and graduation, it can be difficult to remember the correct answers to interview questions, though. An interview Question and Answer discussion can be very helpful to both these individuals.  It is simply a way to go back over the building blocks of a topic.  Many times a simple review like this will help “jog” your memory, and all those previously-memorized facts will come flooding back to you.  It is not a way to re-learn a topic, but a way to remind yourself of what you already know. A Question and Answer discussion can also be a way to go over old topics in a more interesting manner.  Especially if you have been working in the industry, or taking lots of classes on the topic, everything you read can sound like a repeat of what you already know.  Going over a topic in a new format can make the material seem fresh and interesting.  And an interested mind will be more engaged and remember more in the end. Interview Questions and Answers are Harmful A common argument against a Question and Answer discussion is that it will give someone a “cheat sheet.” A new guy with relatively little experience can read the interview questions and answers, and then memorize them. When an interviewer asks him the same questions, he will repeat the answers and get the job. Honestly, is he good hire because he memorized the interview questions? Wouldn’t it be better for the interviewer to hire someone with actual experience?  The answer is not as easy as it seems – there are many different factors to be considered. If the interviewer is asking fundamentals-related questions only, he gets the answers he wants to hear, and then hires this first candidate – there is a good chance that he is hiring based on personality rather than experience.  If the interviewer is smart he will ask deeper questions, have more than one person on the interview team, and interview a variety of candidates.  If one interviewee happens to memorize some answers, it usually doesn’t mean he will automatically get the job at the expense of more qualified candidates. Another argument against interview Question and Answers is that it will give candidates a false sense of confidence, and that they will appear more qualified than they are. Well, if that is true, it will not last after the first interview when the candidate is asked difficult questions and he cannot find the answers in the list of interview Questions and Answers.  Besides, confidence is one of the best things to walk into an interview with! In today’s competitive job market, there are often hundreds of candidates applying for the same position.  With so many applicants to choose from, interviewers must make decisions about who to call back and who to hire based on their gut feeling.  One drawback to reading an interview Question and Answer article is that you might sound very boring in your interview – saying the same thing as every single candidate, and parroting answers that sound like someone else wrote them for you – because they did.  However, it is definitely better to go to an interview prepared, just make sure that you give a lot of thought to your answers to make them sound like your own voice.  Remember that you will be hired based on your skills as well as your personality, so don’t think that having all the right answers will make get you hired.  A good interviewee will be prepared, confident, and know how to stand out. My Opinion A list of interview Questions and Answers is really helpful as a refresher or for beginners. To really ace an interview, one needs to have real-world, hands-on experience with SQL Server as well. Interview questions just serve as a starter or easy read for experienced professionals. When I have to learn new technology, I often search online for interview questions and get an idea about the breadth and depth of the technology. Next Action I am going to write about interview Questions and Answers for next 30 days. I have previously written a series of interview questions and answers; now I have re-written them keeping the latest version of SQL Server and current industry progress in mind. If you have faced interesting interview questions or situations, please write to me and I will publish them as a guest post. If you want me to add few more details, leave a comment and I will make sure that I do my best to accommodate. Tomorrow we will start the interview Questions and Answers series, with a few interesting stories, best practices and guest posts.
