  • Discover What Powers Your Favorite Websites

    - by Matthew Guay
    Have you ever wondered if the site you’re visiting is powered by WordPress or if the webapp you’re using is powered by Ruby on Rails?  With these extensions for Google Chrome, you’ll never have to wonder again. Geeks love digging under the hood to see what makes their favorite apps and sites tick.  But opening the “View Source” window today doesn’t tell you everything there is to know about a website.  Plus, even if you can tell what CMS is powering a website from its source, it can be tedious to dig through lines of code to find what you’re looking for.  Also, the HTML code never tells you what web server a site is running on or what version of PHP it’s using.  With three extensions for Google Chrome you’ll never have to wonder again.  Note that some sites may not give as much information, but still, you’ll find enough data from most sites to be interesting. Discover Web Frameworks and Javascript Libraries with Chrome Sniffer If you want to know what CMS is powering a site or if it’s using Google Analytics or Quantcast, this is the extension for you.  Chrome Sniffer (link below) identifies over 40 different frameworks, and is constantly adding more.  It shows the logo of the main framework on the site on the left of your address bar.  Here wee see Chrome Sniffer noticed that How-To Geek is powered by WordPress.   Click the logo to see other frameworks on the site.  We can see that the site also has Google Analytics and Quantcast.  If you want more information about the framework, click on its logo and the framework’s homepage will open in a new tab. As another example, we can see that the Tumblr Staff blog is powered by Tumblr (of course), the Discus comment system, Quantcast, and the Prototype JavaScript framework. Or here’s a site that’s powered by Drupal, Google Analytics, Mollom spam protection, and jQuery.  Chrome Sniffer definitely uncovers a lot of neat stuff, so if you’re into web frameworks you’re sure to enjoy this extension. Find Out What Web Server The Site is Running On Want to know whether the site you’re looking at is running on IIS or Appache?  The Web Server Notifier extension for Chrome (link below) lets you easily recognize the web server a site is running on by its favicon on the right of the address bar.  Click the icon to see more information. Some web servers will show you a lot of information about their server, including version, operating system, PHP version, OpenSSL version, and more. Others will simply tell you their name. If the site is powered by IIS, you can usually tell the version of Windows Server its running on since the IIS versions are specific to a version of Windows.  Here we see that Microsoft.com is running on the latest and greatest – Windows Server 2008 R2 with IIS 7.5. Discover Web Technologies Powering Sites Wondering if a webapp is powered by Ruby on Rails or ASP.NET?  The Web Technology Notifier extension for Chrome (link below), from the same developer as the Web Server Notifier, will let you easily discover the backend of a site.  You’ll see the technology’s favicon on the right of your address bar, and, as with the other extension, can get more information by clicking the icon. Here we can see that Backpack from 37signals is powered by the Phusion Passenger module to run Ruby on Rails.   Microsoft’s new Docs.com Office Online apps is powered by ASP.NET…   And How-To Geek has PHP running to power WordPress. Conclusion With all these tools at hand, you can find out a lot about your favorite sites.  For example, with all three extensions we can see that How-To Geek runs on WordPress with PHP, uses Google Analytics and Quantcast, and is served by the LightSpeed web server.  Fun info, huh?   Links Download the Chrome Sniffer extension Download the Web Server Notifier extension Download the Web Technology Notifier extension Similar Articles Productive Geek Tips Enjoy a Clean Start Page with New Tab PageEnjoy Image Zooming on Your Favorite Photo Websites in ChromeAdd Your Own Folders to Favorites in Windows 7Find User Scripts for Your Favorite Websites the Easy WayAdd Social Elements to Your Gmail Contacts with Rapportive TouchFreeze Alternative in AutoHotkey The Icy Undertow Desktop Windows Home Server – Backup to LAN The Clear & Clean Desktop Use This Bookmarklet to Easily Get Albums Use AutoHotkey to Assign a Hotkey to a Specific Window Latest Software Reviews Tinyhacker Random Tips Xobni Plus for Outlook All My Movies 5.9 CloudBerry Online Backup 1.5 for Windows Home Server Snagit 10 tinysong gives a shortened URL for you to post on Twitter (or anywhere) 10 Superb Firefox Wallpapers OpenDNS Guide Google TV The iPod Revolution Ultimate Boot CD can help when disaster strikes

  • Walmart and Fusion Apps

    - by ultan o'broin
    Photograph: Misha Vaughan I attended Fusion Apps (yes, I know I am supposed to say "Oracle Fusion Applications", but stuffy old style guides are a turn-off in interwebs conversations) User Experience Advocate (FXA) training in Long Beach, California last week; a suitable location as ODTUG KSCOPE 11 was kicking off and key players were in the area. As a member of Oracle's Apps-UX team I know the Fusion Apps messaging, natch, and done some other Fusion Apps go-to-market content work too. For the messaging details themselves, see Lonneke Dikmans (@lonnekedikmans) great blog, by the way. However, I wanted some 'formal' training combined with the opportunity to meet and learn from people already out there delivering those messages. The idea in me reaching out to Misha Vaughan, Apps-UX FXA maven, to get me onto this training was that in addition to my UX knowledge, I could leverage my location in EMEA and hit up customer events more quickly and easily. Those local user groups do like to hear the voice of locals too you know (so I need to work on that mid-Atlantic accent). I'm looking forward to such opportunities. The training was all smashing stuff, just the right level of detail, delivered professionally and with great style and humor. I was especially honored to be paired off for my er, coaching with Debra Lilley (@debralilley), who shared with everyone all kinds of tips and insights from her experiences of delivering the message and demo. For me, that was the real power of the FXA event--the communal, conversational aspect--the meeting up with people who had done all this for real, the sharing in their experiences, while learning along with other newbies. Sorry, but that all-important social aspect doesn't work so well with remote meetings. Katie Candland (Apps-UX) gave us a great tour of the Fusion Apps demo and included some useful presentational tips too (any excuse to buy that iPad). It's clear to me that the Fusion Apps messaging and demos really come alive with real-world examples that local application users will recognize, and I picked up some "yes, that's my job made easier" scene-stealers from Debra and Karen Brownfield too, to add to the great ones already provided. This power of examples shouldn't surprise anyone, they've long been a mainstay of applications user assistance, popular with users. We'll offer customers different types of example topics in the Fusion Apps online help too (stay tuned), and we know from research how important those 3S's (stories, scenarios, and simulations) are to users when they consume and apply information. Well, we've got the simulation, now it's time for more stories and scenarios. If you get a chance to participate in an FXA event (whether you are an Oracle employee or otherwise), I'd encourage it. It's committing your time and energy for sure, but I got real bang for the buck from it for my everyday job too. Listening to the room's feedback on the application demo really brought our internal design work to life, and I picked up on some things that I need to follow up on (like how you alphabetically sort stuff in other languages). User experience is after all, about users. What will I be doing next, and what would I like to see happen? Obviously, I need to develop my story-telling links with the people I met in Long Beach and do some practicing with the materials, and then get out there and deliver them at a suitable location. The demo is what it is right now, and that's a super-rich demo that I know everyone will want to see and ask questions about. Then, as mentioned by attendees at the FXA event, follow up on those translated and localized messages for EMEA (and APAC), that deal with different statutory or reporting requirements of the target markets. Given my background I would say that, wouldn't I? However, language is part of the UX, and international revenue is greater than US-only revenue for Oracle, so yes dear, we all need to get over the fact that enterprise apps users don't all speak, or want to speak, American-English. Most importantly perhaps, the continued development of a strong messaging community between Oracle and partners and customers where we can swap and share those FXA messaging stories and scenarios about Fusion Apps in a conversational way. The more the better, a combination of online and face-to-face meetings. I must also mention the great dinner after the event at Parker's Lighthouse, and the fun myself and Andrew Gilmour (Apps-UX) had at our end of the table talking about just about everything except Fusion Apps with Ronald Van Luttikhuizen and Ben Prusinski (who now understands the difference between Cork and Dublin people. I hope). Thanks to all the Apps-UXers who helped bring the FXA training to town, and to Debra and all the others that I am too jetlagged to mention right who were instrumental in making it happen for me. Here's to the next one. And the Walmart angle? That was me doing my Robert Scoble (ScO'bilizer?)-style guerilla smart phone research in Walmart in Long Beach, before the FXA event. It's all about stories for me. You can read more about it on the appslab blog (see the comments).

  • Learning about security and finding exploits

    - by Jayraj
    First things first: I have absolutely no interest in learning how to crack systems for personal enrichment, hurting other people or doing anything remotely malicious. I understand the basis of many exploits (XSS, SQL injection, use after free etc.), though I've never performed any myself. I even have some idea about how to guard web applications from common exploits (like the aforementioned XSS and SQL injection) Reading this question about the Internet Explorer zero-day vulnerability from the Security SE piqued my curiosity and made me wonder: how did someone even find out about this exploit? What tools did they use? How did they know what to look for? I'm wary about visiting hacker dens online for fear of getting my own system infected (the Defcon stories make me paranoid). So what's a good, safe place to start learning?

  • HSSFS Part 3: SQL Saturday is Awesome! And DEFAULT_DOMAIN(), and how I found it

    - by Most Valuable Yak (Rob Volk)
    Just a quick post I should've done yesterday but I was recovering from SQL Saturday #48 in Columbia, SC, where I went to some really excellent sessions by some very smart experts.  If you have not yet attended a SQL Saturday, or its been more than 1 month since you last did, SIGN UP NOW! While searching the OBJECT_DEFINITION() of SQL Server system procedures I stumbled across the DEFAULT_DOMAIN() function in xp_grantlogin and xp_revokelogin.  I couldn't find any information on it in Books Online, and it's a very simple, self-explanatory function, but it could be useful if you work in a multi-domain environment.  It's also the kind of neat thing you can find by using this query: SELECT OBJECT_SCHEMA_NAME([object_id]) object_schema, name FROM sys.all_objects WHERE OBJECT_DEFINITION([object_id]) LIKE '%()%'  ORDER BY 1,2 I'll post some elaborations and enhancements to this query in a later post, but it will get you started exploring the functional SQL Server sea. UPDATE: I goofed earlier and said SQL Saturday #46 was in Columbia. It's actually SQL Saturday #48, and SQL Saturday #46 was in Raleigh, NC.

  • Convert rotation from Right handed System to left handed

    - by Hector Llanos
    I have Euler angles from a right handed system that I am trying to convert to a left handed system. All the information that I have read online says that to convert it simply multiply the axis and the angle in the correct order and it should work. In other words, Z * Y * X. When I do this what I see in Maya, and in engine still do not match up. This is what I have so far: static Quaternion ConvertToRightHand(Vector3 Euler) { Quaternion x = Quaternion.AngleAxis(-Euler.x, Vector3.right); Quaternion y = Quaternion.AngleAxis(Euler.y, Vector3.up); Quaternion z = Quaternion.AngleAxis(Euler.z, Vector3.forward); return (z * y * x); } Keeping the -Euler.x helps keep the object pointing up correctly, but when I pass ( 0,0,0) to face in the -z, it faces in the +z. Help :/

  • Who owns the intellectual property to Fragile Allegiance?

    - by analytik
    Fragile Allegiance was developed by Gremlin Interactive, which was later acquired by Infogrames (Atari). I couldn't find any details of the acquisition though. The only interesting thing I have found online is that the owner of the registered trademark Fragile Allegiance is Interplay, who published Fragile Allegiance. However, the only copyright note I've found was in one installation .ini file, claiming it for Gremlin. What are the common business practices when it comes to old, unused IPs? What do publishers/developers actually need to legally claim an intellectual property? Does anyone have an experience with contacting big publishers with copyright/IP inquiries? Related legal question.

  • How to refactor an OO program into a functional one?

    - by Asik
    I'm having difficulty finding resources on how to write programs in a functional style. The most advanced topic I could find discussed online was using structural typing to cut down on class hierarchies; most just deal with how to use map/fold/reduce/etc to replace imperative loops. What I would really like to find is an in-depth discussion of an OOP implementation of a non-trivial program, its limitations, and how to refactor it in a functional style. Not just an algorithm or a data structure, but something with several different roles and aspects - a video game perhaps. By the way I did read Real-World Functional Programming by Tomas Petricek, but I'm left wanting more.

  • Calculating instantaneous speed and acceleration for a simple Car software model

    - by Dylan
    I am trying to model a speedometer and tachometer for a simple software model of a car dashboard. I want this to be relatively simple, so for my purposes I won't likely simulate variables such as drag (or, assume that drag is a constant). But I would like to know the general formulas for: 1) Calculating the RPM, depending on a position of a graphical slider representing the accelerator. 2) Using this information to find the instantaneous speed (or, magnitude of instantaneous velocity?). I am not sure, in the case of 2), what other independent variables I need to consider. Do I need to consider the frequency of rotation of the wheels (assuming a fixed radius), in addition to the RPM? If anyone can give me a rough explanation plus relevant formulas, or alternatively direct me to other trusted resources online (I have had a hard time sifting through info and determining the accuracy), it would be much appreciated.

  • Can't find ALL wireless networks, just my neighbours

    - by motoringeek
    Been playing with live discs since 10.10 but now have gone ahead and dual booted. I have a Acer 5742z with a Nplify 802.11b/g/n wireless connection. The install went well and drivers seem to be working. BUT, although wireless detects some local networks it doesn't find mine. I have WPA-PSK security on my modem, could this be the problem?? I don't want to change my modem settings as all my other WIFI devices are contected to it. So I need help in finding my home network. A step by step guide would be useful. I am using Windows 7 now to write this but would love it if I could use Ubuntu online. I only can when I connect an Ethernet cable. Thanks in advance.

  • Not attending the LUGM mini-meetup - 05. Oct 2013

    Not attending a meeting of the LUGM can be fun, too. It's getting a bit of a habit that Ish is organising small gatherings, aka mini-meetups, of the Linux User Group Mauritius/Meta (LUGM) almost every Saturday. There they mainly discuss and talk about various elements of using Linux as ones main operating systems and the possibilities you are going to have. On top of course, some tips & tricks about mastering the command line and initial steps in scripting or even writing HTML. In general, sounds like a good portion of fun and great spirit of community. Unfortunately, I'm usually quite busy with private and family matters during the weekend and so I already signalised that I wouldn't be around. Well, at least not physically... But this Saturday a couple of things worked out faster than expected and so I was hanging out on my machine. I made virtual contact with one of Pawan's messages over on Facebook... And somehow that kicked off some kind of an online game fun on basic configuration of Apache HTTPd 2.2.x, PHP 5.x and how to improve the overall performance of a newly installed blog based on WordPress. Default configuration files Nitin's website finally came alive and despite the dark theme and the hidden Apple 'fanboy' advertisement I was more interested in the technical situation. As with any new installation there is usually quite some adjustment to be done. And Nitin's page was no exception. Unfortunately, out of the box installations of Apache httpd and PHP are too verbose and expose too much information under the hood. You might think that this isn't really a problem at all, well, think about it again after completely reading this article. First, I checked the HTTP response headers - using either Chrome Developer Tools or Firefox Web Developer extension - of Nitin's page and based on that I advised him to lower the noise levels a little bit. It's not really necessary that detailed information about web server software and scripting language has to be published in every response made. Quite a number of script kiddies and exploits actually check for version specifics prior to an attack. So, removing at least version details hardens the system a little bit. In particular, I'm talking about these response values: Server X-Powered-By How to achieve that? By tweaking the configuration files... Namely, we are going to look into the following ones: apache2.conf httpd.conf .htaccess php.ini The above list contains some additional files, I'm talking about in the next paragraphs. Anyway, those are the ones involved. Tweaking Apache Open your favourite text editor and start to modify the apache2.conf. Eventually, you might like to have a quick peak at the file to see whether it is necessary to adjust it or not. Following is a handy combination of commands to get an overview of your active directives: # sudo grep -v '#' /etc/apache2/apache2.conf | grep -v '^$' | less There you keep an eye on those two Apache directives: ServerSignature Off ServerTokens Prod If that's not the case, change them as highlighted above. In order to activate your modifications you have to restart Apache httpd server. On Debian and Ubuntu you might use apache2ctl for that, on other distributions you might have to use service or run the init-scripts again: # sudo apache2ctl configtestSyntax OK# sudo apache2ctl restart Refresh your website and check the HTTP response header. Tweaking PHP5 (a little bit) Next, check your php.ini file with the following statement: # sudo grep -v ';' /etc/php5/apache2/php.ini | grep -v '^$' | less And check the value of expose_php = Off Again, if it's not as highlighted, change it... Some more Apache love Okay, back to Apache it might also be interesting to improve the situation about browser caching and removing more obsolete information. When you run your website against the usual performance checks like Google Page Speed and Yahoo YSlow you might see those check points with bad grades on a standard, default configuration. Well, this can be done easily. Configure entity tags (ETags) ETags are only interesting when you run your websites on a farm of multiple web servers. Removing this data for your static resources is very simple in Apache. As we are going to deal with the HTTP response header information you have to ensure that Apache is capable to manipulate them. First, check your enabled modules: # sudo ls -al /etc/apache2/mods-enabled/ | grep headers And in case that the 'headers' module is not listed, you have to enable it from the available ones: # sudo a2enmod headers Second, check your httpd.conf file (in case it exists): # sudo grep -v '#' /etc/apache2/httpd.conf | grep -v '^$' | less In newer (better said fresh) installations you might have to create a new configuration file below your conf.d folder with your favourite text editor like so: # sudo nano /etc/apache2/conf.d/headers.conf Then, in order to tweak your HTTP responses either check for those lines or add them: Header unset ETagFileETag None In case that your file doesn't exist or those lines are missing, feel free to create/add them. Afterwards, check your Apache configuration syntax and restart your running instances as already shown above: # sudo apache2ctl configtestSyntax OK# sudo apache2ctl restart Add Expires headers To improve the loading performance of your website, you should take some care into the proper configuration of how to leverage the browser's ability to cache certain resources and files. This is done by adding an Expires: value to the HTTP response header. Generally speaking it is advised that you specify a near-future, read: 1 week or a little bit more, for your static content like JavaScript files or Cascading Style Sheets. One solution to adjust this is to put some instructions into the .htaccess file in the root folder of your web site. Of course, this could also be placed into a more generic location of your Apache installation but honestly, I'd like to keep this at the web site level. Following some adjustments I'm currently using on this blog site: # Turn on Expires and set default to 0ExpiresActive OnExpiresDefault A0 # Set up caching on media files for 1 year (forever?)<FilesMatch "\.(flv|ico|pdf|avi|mov|ppt|doc|mp3|wmv|wav)$">ExpiresDefault A29030400Header append Cache-Control "public"</FilesMatch> # Set up caching on media files for 1 week<FilesMatch "\.(js|css)$">ExpiresDefault A604800Header append Cache-Control "public"</FilesMatch> # Set up caching on media files for 31 days<FilesMatch "\.(gif|jpg|jpeg|png|swf)$">ExpiresDefault A2678400Header append Cache-Control "public"</FilesMatch> As we are editing the .htaccess files, it is not necessary to restart Apache. In case that your web site doesn't load anymore or you're experiencing an error while trying to restart your httpd, check that the 'expires' module is actually an enabled module: # ls -al /etc/apache2/mods-enabled/ | grep expires# sudo a2enmod expires Of course, the instructions above a re not feature complete but I hope that they might provide a better default configuration for your LAMP stack. Resume of the day Within a couple of hours, and while being occupied with an eLearning course on SQL Server 2012, I had some good fun in helping and assisting other LUGM members while they were some kilometers away at Bagatelle. According to other blog articles it seems that Nitin had quite some moments of desperation. Just for the records: At no time it was my intention to either kick his butt or pull a leg on him. Simply, providing some input based on the lessons I've learned over the last couple of years configuring Apache HTTPd and PHP. Check out the other blogs, too: LUGM mini-meetup... Epic! Superb Saturday Linux Meetup And last but not least, the man himself: The end of a new beginning Cheers, and happy community'ing! Updates Due to our weekly Code & Coffee sessions in the MSCC community, I had a chance to talk to Nitin directly and he showed me the problems directly on his machine. This led to update this article hence the paragraphs on enabling the modules 'headers' and 'expires'.

  • Enforce VPN connection to access the Internet

    - by ch0wn
    I'm using a VPN when I'm online at an unencrypted wifi. Unfortunately, at my university the connection is quite unstable and at every reconnect the VPN connection is terminated and I manually need to reconnect to it using the NetworkManager, which obviously only works if I notice the reconnect. I enabled the option to automatically connect to the VPN in the NM options, but it seems to have no effect. Is there a way to enforce an active VPN connection before any other application can access the network connection so I can be sure not to send private data over unencrypted connections? Cheers, Pascal

  • Where can I start learning to build web applications in C#

    - by Carson Myers
    So far I've written web sites in PHP, except for a pet project of mine written in Python. I'd like to start learning C# for use on the web, but I have no idea where to start. I know nothing of .Net. Are there any good tutorials or online books etc. which give a brief intro to the .Net environment (specifically C#, and specifically for the web)? I'm not even sure what I need to install. Visual Studio I guess, but what else? Anything special, or will VS do the trick?
