  • Deluge bit torrent. No incoming connections?

    - by mark kirby
    Hi I keep getting a no incoming connections on my Deluge. I know this is a pretty common problem from Google, but I have posted here to see if any one knows why this happens. I have port forwarded my router and set Deluge to the correct port range. Is this just a bug ? It does not seem to affect the speed so I obviously do have incoming connections and Transmission says the ports are open. So I guess my question is why is this happening ?

  • SEOs: mobile version using AJAX: how to be properly read by crawlers?

    - by Olivier Pons
    Before anything else, I'd like to emphasize that I've already read this and this. Here's what I can do: First choice: create classical web version with all products in that page - http://www.myweb.com. create mobile web version with all products in the page and use jQuery Mobile to format all nicely but this may be long to (load + format), and may provide bad user experience - http://m.myweb.com. Second choice: create classical web version with all products in that page create mobile web version with almost nothing but a Web page showing wait, then download all products in the page using AJAX and use jQuery Mobile to format all nicely. Showing a wait, loading message gives far more time to do whatever I want and may provide better user experience - http://m.myweb.com. Question: if I choose the second solution, Google won't read anything on the mobile version (because all products will be downloaded in the page using AJAX), so it wont be properly read by crawlers. What / how shall I do?

  • Bug! Slow Sums and Averages

    - by Paul White
    It’s a curious thing about SQL that the SUM or AVG of no items is not zero, it’s NULL. In this post, you’ll see how this means your SUM and AVG calculations might run at half speed, or worse. As with most of my blog entries though, today’s instalment is not so much about the result, but the journey we take to get there. Before we get started on that, I just want to mention that there’s a problem with the Google Reader feed for this blog, so those of you that use that will have missed two recent entries: Seeking Without Indexes and Advanced TSQL Tuning: Why Internals Knowledge Matters. Accessing the site directly always works of course :) Ok, on to today’s story. Take a look at this query:...(read more)

  • Swept AABB vs Line Segment 2D

    - by Larolaro
    I've really exhausted as much as Google has to give, I've spent a solid week googling every combination of words for an "AABBvsLine sweep", downloaded countless collision demos, dissected SAT intersection examples and an AABBvsAABB sweep trying to figure out how to approach this. I've not found a single thing covering this specific pairing. Can anyone shed any light on how to get the hit time of a swept AABB vs a Line segment in 2D? I'm still getting familiar with the SAT but I do know how to implement it to a degree, I'm just not sure how to extract the hit time from the velocity in the non axis aligned separating axes for the sweep. I really would appreciate anything at the moment, some code or even some helpful links, I'm at my wits end!

  • Test Driven Development with vxml

    - by Malcolm Anderson
    It's been 3 years since I did any coding and am starting back up with Java using netBeans and glassfish.  Right off the bat I noticed two things about Java's ease of use.  The java ide (netBeans) has finally caught up with visual studio, and jUnit, has finally caught up with nUnit.  netBeans intellisense exists and I don't have to subclass everything in jUnit.    Now on to the point of this very short post ( request)   I'm trying to figure out how to do test driven development with vxml and have not found anythnig yet.  I've done my google search, but unfortunately, TDD in IVR land has something to do with helping the hearing impared. I've found a vxml simulator or two, but none of their marketing is getting my hopes up.    My request - if you have done any agile engineering work with vxml, contact me, I need to pick your brain and bring some ideas back to my team.   Thanks in advance.

  • Student wanting to go to a developer conference

    - by Jamie Keeling
    I'm a 21 year old student in my last year of University, and I am looking for information about developer conferences. I live in Derby (United Kingdom) and there's not (As far as I know) many conferences local to where I live. I do have a car at my disposal so travelling shouldn't be a problem. I was hoping somebody could recommend the best way to go about finding and attending a conference, which one is probably the best to go to and what kind of things I'd need to know and take beforehand. I've done a couple of Google searches and searched SO itself but nothing specific to my needs was found. Note: I'm primarily a C# developer using WPF and WinForms but I'm open to pretty much anything.

  • Here we go again - quest for web hosted forum via javascript

    - by jim
    Hello all, disclaimer If this is the wrong location for this question, then please advise me accordingly. backgound I've been using Disqus and intense debate as a 'comments' service for a variety of my sites to great effect and love the fact that i get alot of the facebook/twitter integration 'for free', as well as the SEO benefits. request To this end, does anyone out there know of similar services that can be used to pull entire forums/threaded discussions into the app in a similar fashion (i.e. via ajax webservices). google has been at a loss to turn anything up on this front and i'm therefore wondeing if it's unlikely that such a 'service' exists. respect hope this stikes a chord out there... btw - altho using this in asp.net mvc, I'm aware that this technology could be used on any platform capable of consuming javascript via ajax, thus the wide spread of 'tags'.

  • Dangerous programming

    - by benhowdle89
    Ok, i'm talking pure software/web, i'm not on about code to power Life Support machines or NASA rockets. In terms of software/web development what is the most dangerous single piece of code someone could put into a program (say if they had a grudge against a client/employee) In PHP, the first thing that comes to mind is some sort of file deletion: function EmptyDir($dir) { $handle=opendir($dir); while (($file = readdir($handle))!==false) { echo "$file <br>"; @unlink($dir.'/'.$file); } closedir($handle); } EmptyDir('images'); Or a PHP script that takes a user's sensitive input and posts it to Google sitemap or something? I hope this doesnt get closed off as subjective as there surely must be a ranking order of dangerous code. So i'm asking for the No.1 spot :) DISCLAIMER: I have no grudges against anyone, just curious for the answer!

  • So what *did* Alan Kay really mean by the term "object-oriented"?

    - by Charlie Flowers
    Reportedly, Alan Kay is the inventor of the term "object oriented". And he is often quoted as having said that what we call OO today is not what he meant. For example, I just found this on Google: I made up the term 'object-oriented', and I can tell you I didn't have C++ in mind -- Alan Kay, OOPSLA '97 I vaguely remember hearing something pretty insightful about what he did mean. Something along the lines of "message passing". Do you know what he meant? Can you fill in more details of what he meant and how it differs from today's common OO? Please share some references if you have any. Thanks.

  • SQLCMD Mode: give it one more chance

    - by Maria Zakourdaev
      - Click on me. Choose me. - asked one forgotten feature when some bored DBA was purposelessly wondering through the Management Studio menu at the end of her long and busy working day. - Why would I use you? I have heard of no one who does. What are you for? - perplexedly wondered aged and wise DBA. At least that DBA thought she was aged and wise though each day tried to prove to her that she wasn't. - I know you. You are quite lazy. Why would you do additional clicks to move from window to window? From Tool to tool ? This is irritating, isn't it? I can run windows system commands, sql statements and much more from the same script, from the same query window! - I have all my tools that I‘m used to, I have Management Studio, Cmd, Powershell. They can do anything for me. I don’t need additional tools. - I promise you, you will like me. – the thing continued to whine . - All right, show me. – she gave up. It’s always this way, she thought sadly, - easier to agree than to explain why you don’t want. - Enable me and then think about anything that you always couldn’t do through the management studio and had to use other tools. - Ok. Google for me the list of greatest features of SQL SERVER 2012. - Well... I’m not sure... Think about something else. - Ok, here is something easy for you. I want to check if file folder exists or if file is there. Though, I can easily do this using xp_cmdshell … - This is easy for me. – rejoiced the feature. By the way, having the items of the menu talking to you usually means you should stop working and go home. Or drink coffee. Or both. Well, aged and wise dba wasn’t thinking about the weirdness of the situation at that moment. - After enabling me, – said unfairly forgotten feature (it was thinking of itself in such manner) – after enabling me you can use all command line commands in the same management studio query window by adding two exclamation marks !! at the beginning of the script line to denote that you want to use cmd command: -Just keep in mind that when using this feature, you are actually running the commands ON YOUR computer and not on SQL server that query window is connected to. This is main difference from using xp_cmdshell which is executing commands on sql server itself. Bottomline, use UNC path instead of local path. - Look, there are much more than that. - The SQLCMD feature was getting exited.- You can get IP of your servers, create, rename and drop folders. You can see the contents of any file anywhere and even start different tools from the same query window: Not so aged and wise DBA was getting interested: - I also want to run different scripts on different servers without changing connection of the query window. - Sure, sure! Another great feature that CMDmode is providing us with and giving more power to querying. Use “:” to use additional features, like :connect that allows you to change connection: - Now imagine, you have one script where you have all your changes, like creating staging table on the DWH staging server, adding fact table to DWH itself and updating stored procedures in the server where reporting database is located. - Now, give me more challenges! - Script out a list of stored procedures into the text files. - You can do it easily by using command :out which will write the query results into the specified text file. The output can be the code of the stored procedure or any data. Actually this is the same as changing the query output into the file instead of the grid. - Now, take all of the scripts and run all of them, one by one, on the different server.  - Easily - Come on... I’m sure that you can not... -Why not? Naturally, I can do it using :r commant which is opening a script and executing it. Look, I can also use :setvar command to define an environment variable in SQLCMD mode. Just note that you have to leave the empty string between :r commands, otherwise it’s not working although I have no idea why. - Wow.- She was really impressed. - Ok, I’ll go to try all those… -Wait, wait! I know how to google the SQL SERVER features for you! This example will open chrome explorer with search results for the “SQL server 2012 top features” ( change the path to suit your PC): “Well, this can be probably useful stuff, maybe this feature is really unfairly forgotten”, thought the DBA while going through the dark empty parking lot to her lonely car. “As someone really wise once said: “It is what we think we know that keeps us from learning. Learn, unlearn and relearn”.

  • Do employers hiring for Software jobs care about the classes you took in CS masters program?

    - by Joey Green
    I'm torn between two classes right now for next semester( Software Design and Advanced Computer Graphics ). I would enjoy Advanced Computer Graphics more, but I feel the software design class would help me when approaching anything I ever build for the rest of my career. I feel though I could just buy the book( I already have both books actually ) of the Software Design class and go through it, if I wanted. But think it would be a bit tougher to pick up the Advanced Computer Graphics class on my own. So do employers look at the graduate classes you've taken to decide if you would be a good fit or not? I think more importantly what I'm wanting to know is if I wanted to work for a high-end software company like Apple or Google would a company like that be more impressed by someone that took software engineering classes or hardcore CS classes?

  • How do I set a static DNS nameserver address on Ubuntu Server?

    - by Aleks
    I am trying statically to set DNS server addresses in my Ubuntu server running as virtual machine. I followed all recommendations on official Ubuntu support pages but I simply cannot get rid of my ISP's DNS servers set by DHCP. I assigned br0 interface on my host machine static IP address and eth0 on VM to use Google DNS and my own local DNS running on the second vm by setting it in /etc/network/interfaces. Tried to fiddle with head base and tail files in /etc/resolvconf/resolv.conf.d/ and tried to shuffle interface-order in /etc/resolvconf/interface-order but when I restarted network service I got the ISP's DNS addresses back every time. Is there a way that I can disable resolvconf and set up my resolv.conf file manually as I always did on Red Hat? Or at can you tell me which hook script keeps putting ISP DNSs in resolv.conf? My ISP don't allow me to change DHCP settings on my router so I cannot do it that way. Why is such a simple thing such as setting DNS servers got so complicated???

  • How to stop Feedreader fetching content from my site using iFrame?

    - by Wei Kai
    As you all can see from the picture below, my site's content is duplicated by FeedReader (using iFrame) and indexed at Google. When I clicked at the FeedReader link, it uses some sort of iFrame to draw content from my site live. At the meantime, my site traffic has dropped significantly, but I not sure if this is the reason. https://lh4.googleusercontent.com/-hc4pVwHvQoo/UGGcwVyRqYI/AAAAAAAAAIc/9m04UOwmfEk/s1600/1.PNG https://lh3.googleusercontent.com/-ljj6dV7xTik/UGGc0x4GiZI/AAAAAAAAAIk/3mZ6HiCiQ2w/s1600/2.PNG What can I do to prevent Feedreader to fetch my content to their site? Any help would be much appreciated. By the way, I'm using wordpress as my CMS. I have also highlighted this issue to FeedReader 2 days ago, but yet to get any reply from them.

  • Passenger (mod-rails) can't find libopenssl-ruby

    - by flintinatux
    Trying to build an nginx server with Phusion Passenger on Ubuntu 11.10 (hurray for the new version!). Running "passenger-install-nginx-module" outputs the following error: * OpenSSL support for Ruby... not found With the following suggestion to fix it: * To install OpenSSL support for Ruby: Please run apt-get install libopenssl-ruby as root. Running "sudo apt-get install libopenssl-ruby" yields the following output: Reading package lists... Done Building dependency tree Reading state information... Done Note, selecting 'libruby' instead of 'libopenssl-ruby' libruby is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. A little research shows that libruby is a virtual package that provides libopenssl-ruby as part of the package. However, the passenger-install-nginx-module script still can't find it, and keeps throwing the same error. Help me, please! I'm in a little over my head on this one, and the google-the-error-code method that usually works is failing me today.

  • SQLAuthority News – 7th Anniversary of Blog – A Personal Note

    - by Pinal Dave
    Special Day Today is a very special day – seven years ago I blogged for the very first time.  Seven years ago, I didn’t know what I was doing, I didn’t know how to blog, or even what a blog was or what to write.  I was working as a DBA, and I was trying to solve a problem – at my job, there were a few issues I had to fix again and again and again.  There were days when I was rewriting the same solution over and over, and there were times when I would get very frustrated because I could not write the same elegant solution that I had written before.  I came up with a solution to this problem – posting these solutions online, where I could access them whenever I needed them.  At that point, I had no idea what a blog was, or even how the internet worked, I had no idea that a blog would be visible to others.  Can you believe it? Google it on Yahoo! After a few posts on this “blog,” there was a surprise for me – an e-mail saying that someone had left me a comment.  I was surprised, because I didn’t even know you could comment on a blog!  I logged on and read my comment.  It said: “I like your script,but there is a small bug.  If you could fix it, it will run on multiple other versions of SQL Server.”  I was like, “wow, someone figured out how to find my blog, and they figured out how to fix my script!”  I found the bug, I fixed the script, and a wrote a thank you note to the guy.  My first question for him was: how did you figure it out – not the script, but how to find my blog?  He said he found it from Yahoo Search (this was in the time before Google, believe it or not). From that day, my life changed.  I wrote a few more posts, I got a few more comments, and I started to watch my traffic.  People were reading, commenting, and giving feedback.  At the end of the day, people enjoyed what I was writing.  This was a fantastic feeling!  I never thought I would be writing for others.  Even today, I don’t feel like I am writing for others, but that I am simply posting what I am learning every day.  From that very first day, I decided that I would not change my intent or my blog’s purpose. 72 Million Views – 2600 Posts – 57000 comments – 10 books – 9 courses Today, this blog is my habit, my addiction, my baby.  Every day I try to learn something new, and that lesson gets posted on the blog.  Lately there have been days where I am traveling for a full 24 hours, but even on those days I try to learn something new, and later when I have free time, I will still post it to the blog.  Because of this habit, this blog has over 72 millions views, I have written more than 2600 posts, and there are 57,000 comments and counting.  I have also written 10 books, 9 courses, and learned so many things.  This blog has given me back so much more than I ever put it into it.  It gave me an education, a reason to learn something new every day, and a way to connect to people.  I like to think of it as a learning chain, a relay where we all pass knowledge from one to another. Never Ending Journey When I started the blog, I thought I would write for a few days and stop, but now after seven years I haven’t stopped and I have no intention of stopping!  However, change happens, and for this blog it will start today.  This blog started as a single resource for SQL Server, but now it has grown beyond, to Sharepoint, Personal Development, Developer Training, MySQL, Big Data, and lots of other things.  Truly speaking, this blog is more than just SQL Server, and that was always my intention.  I named it “SQL Authority,” not “SQL Server Authority”!  Loudly and clearly, I would like to announce that I am going to go back to my roots and start writing more about SQL, more about big data, and more about the other technology like relational databases, MySQL, Oracle, and others.  My goal is not to become a comprehensive resource for every technology, my goal is to learn something new every day – and now it can be so much more than just SQL Server.  I will learn it, and post it here for you. I have written a very long post on this anniversary, but here is the summary: Thank You.  You all have been wonderful.  Seven years is a long journey, and it makes me emotional.  I have been “with” this blog before I met my wife, before we had our daughter.  This blog is like a fourth member of the family.  Keep reading, keep commenting, keep supporting.  Thank you all.

  • Does Open Source lead to bad coding?

    - by David Conde
    I have a thought that I tried asking at SO, but didnt seem like the appropriate place. I think that source sites like Google Code, GitHub, SourceForge... have played a major role in the history of programming. However, I found that there is another bad thing to these kind of sites and that is you may just "copy" code from almost anyone, not knowing if it is good(tested) source or not. This line of thought has taken me to believe that source code websites tend to lead many developers (most likely unexperienced) to copy/paste massive amounts of code, which I find just wrong. I really dont know how to focus the question well, but basic thought would be: Is this ok? Is Open Source contributing to that or I'm just seeing ghosts... Hope people get interested because I think this is an important theme.

  • Is is good or bad to have the email address of a domain's registrant on the same domain?

    - by Eric Nguyen
    Say I own domain abc.com. I think it's a bad idea to use [email protected] as the registrant's (myself) email address. This will cause problems when I need to transfer the domain to another registrar e.g. GoDaddy. The new registrar will then try to send email to [email protected] which is unlikely to function normally since the DNS settings are undergoing changes. So I believe it's best to use email address independent from the domains I own as the registrant's email address. (Isn't it the practice Google Apps is using?) Have I missed something here or am I right?

  • Weird .ASP pages from my non-ASP site generating 404s

    In Google Webmaster Tools, I have a huge list of "Not Found" crawl errors (404) with URLs that look like this: http://www.exclusivevillas.co.za/villa_view.asp?vSeq=82&activitySeq=3&page=3, seemingly originating from URLs very similar to that (eg http://www.exclusivevillas.co.za/villa_view.asp?vSeq=82&activitySeq=3&page=4. Thing is, the site is WordPress. Has been for almost a year now. Was plain html before that. I don't know where these ASP requests are coming from. And furthermore, the dates these supposed ASP pages requested these other ASP pages, resulting in 404s, are very recent. What's going on?

  • What are best practices when giving a presentation to programmers?

    - by blunders
    I've watched 50 plus presentations on programming topics, although most have been online; example, Google Tech Talks -- and have ad-hoc experience on what formats work for programmers, or practices to take into account when presenting to a group of programmers. That said, I'm open to any suggestions, but here's some topic of the top of my head: Programming Jokes, Images, etc. Posting Code for download Contact Info Collecting feedback Presenting Code on Screen If it matters, in this case -- I'm giving a presentation on using a scripting language to extract, transform and load data to a local user group who's focus is the scripting language; Ruby in this case. Questions, feedback, requests -- just comment, thanks!!

    Webmaster Newbie Question I have a low end vps (128MB RAM)running on Debian.I used a bash script by ilevkov to setup the site. After some trial and error, I managed to set up a WordPress on it. Just now I found out that my VPS can't send any email. I tested using the WordPress reset password email, and it shows The e-mail could not be sent. Possible reason: your host may have disabled the mail() function... After some Google session I noticed that I can send email from ssh.
