• Chrome and Firefox not able to find some sites after Ubuntu's recent update?

  - by gkr

  Loading of revision3.com in Chrome stops and status saying "waiting for static.inplay.tubemogul.com" grooveshark.com in Chrome never loads But wikipedia.org, google.com works just normal same behavior in Firefox too. I use wired DSL connection in Ubuntu 12.04. I guess this started happening after I upgraded the Chrome browser or Flash plugin few days ago from Ubuntu updates through update-manager. Thanks EDIT: Everything works normal in my WinXP. Problem is only in Ubuntu 12.04. This is what I get when I use wget gkr@gkr-desktop:~$ wget revision3.com --2012-06-12 08:58:01-- http://revision3.com/ Resolving revision3.com (revision3.com)... 173.192.117.198 Connecting to revision3.com (revision3.com)|173.192.117.198|:80... connected.

• Windows8, JavaScript and HTML5 - A good thing?

  - by Albers

  Most of us have seen the Windows 8 news regarding support for native HTML5/JavaScript applications. The press has pushed this as a potential threat to the .NET developer community because JavaScript and HTML5 were called "our new developer platform". The press release refers to "Web-connected and Web-powered apps built using HTML5 and JavaScript that have access to the full power of the PC.".Microsoft has also been hush on details related to these comments. Before we buy the hype and start worrying about a world where we drop our Visual Studio licenses and buy DreamWeaver - let's think about how Windows 8 HTML/JavaScript applications would be implemented. The HTML5 spec offers support for offline applications, but this won't offer the OS-integrated experience the press release refers to. MS has to be planning a way to extend access beyond the traditional JavaScript feature set. Microsoft has a similar option today: HTML Applications or HTAs. They come close to required features, but HTAs need ActiveX or Java integration to provide the promised OS-level access. I'm guessing that Microsoft's future OS strategy isn't built on developers cranking out ActiveX controls or Java applets. So where is Microsoft headed? One possibility is that MS builds a new JavaScript framework from the ground up outside their current APIs. Another idea would be for Microsoft to add support for JavaScript as a first class .NET language using the Dynamic Language Runtime. A solution based on the DLR could be integrated into an HTA-like model to provide the promised access, along with the full range of features in .NET Framework. Security comes included in the Framework. And the work necessary to support this integration would tie in nicely with the effort MS has recently made providing better JavaScript and HTML5 support in Visual Studio 2010. As a bonus, a full-fledged JavaScript DLR implementation would allow single language web solutions across client and server (think node.js) and would appeal to developers who are familiar with JavaScript but have less experience with the Microsoft tech stack. We will all get a better picture after the Build conference in September. But in the mean time we know that Microsoft has a reputation for providing strong developer support. We might want to reserve our harshest judgement and consider that the press release could hint at new opportunities for .NET development.

• Examples of good Javascript/HTML5 based games

  - by Zuch

  Now that Flash is largely being replaced with HTML5 elements (video, audio, canvas, etc.) are there any good examples of web-based games built on completely open standards (meaning Javascript, HTML and CSS)? I see a lot of examples of pure HTML5 implementations of what was once only in Flash (like stuff here: http://www.html5rocks.com/) but not many games, a domain which still seem dominated by Flash. I'm curious what's possible and what the limitations are.

• What is the usage of Spaly Trees in the real world?

  - by Meena

  I decided to learn about Balance search trees, so I picked 2-3-4 and splay trees. I'm wondering what are the examples of splay trees usage in the real world? In this Cornell: http://www.cs.cornell.edu/courses/cs3110/2009fa/recitations/rec-splay.html I read that splay trees are 'A good example is a network router'. But from rest of the explanation seams like network routers use hash tables and not splay trees since the lookup time is constant instead of O(log n). thanks!

• New Slides - and a discussion about Dictionary Statistics

  - by Mike Dietrich

  First of all we have just upoaded a new version of the Upgrade and Migration Workshop slides with some added information. So please feel free to download them from here.The slides have one new interesting information which lead to a discussion I've had in the past days with a very large customer regarding their upgrades - and internally on the mailing list targeting an EBS database upgrade from Oracle 10.2 to Oracle 11.2. Why are we creating dictionary statistics during upgrade? I'd believe this forced dictionary statistics creation got introduced with the desupport of the Rule Based Optimizer in Oracle 10g. The goal: as RBO is not supported anymore we have to make sure that the data dictionary has fresh and non-stale statistics. Actually that would have led in Oracle 9i to strange behaviour in some databases - so in Oracle 9i this was strongly disrecommended. The upgrade scripts got hardcoded to create these stats. But during tests we had the following findings: It's important to create dictionary statistics the night before the upgrade. Not two weeks before, not 60 minutes before your downtime begins. But very close to the upgrade. From Oracle 10g onwards you'd just say: $ execute DBMS_STATS.GATHER_DICTIONARY_STATS; This is important to make sure you have fresh dictionary statistics during upgrade for performance reasons. Tests have shown that running an upgrade without valid dictionary statistics might slow down the whole upgrade by factors of 2x-3x. And it would be also a great idea post upgrade to create again fresh dictionary statistics when you've did suppress the stats creation during the upgrade process. Suppress? Yes, you could set this underscore parameter in the init.ora: _optim_dict_stats_at_db_cr_upg=FALSE to suppress the forced dictionary statistics collection during an upgrade. We believe strongly that (a) people using the default statistics creation process which will create dictionary statistics by default and (b) create fresh stats before upgrade on the dictionary. Therefore we find it save once you have followed our advice to use the underscore during upgrade. And we've taken out that forced statistics collection during upgrade in the next release of the database. Please note: If you are using the DBUA for the upgrade it will remove underscore parameters for the upgrade run to improve performance - which is generally a good idea. So you'll have to start the DBUA with that call: $ dbua -initParam "_optim_dict_stats_at_cb_cr_upg"=FALSE -Mike

• What is a good GUI text editor with code folding on Linux

  - by quanticle

  When I'm on Linux, I usually program using either gvim or emacs (depending on the language I'm working in, and the configuration of the machine). However, one thing I miss from the Windows world is code folding. Editors like Notepad++ and IDEs like Visual Studio allow shrink, or fold, blocks of code into single line headings. Are there any Linux editors with this facility? I know Eclipse can do code folding, but I don't want to launch Eclipse just to edit a HTML file.

• Virtual Lab part 2&ndash;Templates, Patterns, Baselines

  - by Geoff N. Hiten

  Once you have a good virtualization platform chosen, whether it is a desktop, server or laptop environment, the temptation is to build “X”.  “X” may be a SharePoint lab, a Virtual Cluster, an AD test environment or some other cool project that you really need RIGHT NOW.  That would be doing it wrong. My grandfather taught woodworking and cabinetmaking for twenty-seven years at a trade school in Alabama.  He was the first instructor hired at that school and the only teacher for the first two years.  His students built tables, chairs, and workbenches so the school could start its HVAC courses.   Visiting as a child, I also noticed many extra “helper” stands, benches, holders, and gadgets all built from wood.  What does that have to do with a virtual lab, you ask?  Well, that is the same approach you should take.  Build stuff that you will use.  Not for solving a particular problem, but to let the Virtual Lab be part of your normal troubleshooting toolkit. Start with basic copies of various Operating Systems.  Load and patch server and desktop OS environments.  This also helps build your collection of ISO files, another essential element of a virtual Lab.  Once you have these “baseline” images, you can use your Virtualization software’s snapshot capability to freeze the image.  Clone the snapshot and you have a brand new fully patched machine in mere moments.  You may have to sysprep some of the Microsoft OS environments if you are going to create a domain environment or experiment with clustering.  That is still much faster than loading and patching from scratch. So once you have a stock of raw materials (baseline images in this case) where should you start.  Again, my grandfather’s workshop gives us the answer.  In the shop it was workbenches and tables to hold large workpieces that made the equipment more useful.  In a Windows environment the same role falls to the fundamental network services:  DHCP, DNS, Active Directory, Routing, File Services, and Storage services.  Plan your internal network setup.  Build out an AD controller with all the features listed.  Make the actual domain an isolated domain so it will not care about where you take it.  Add the Microsoft iSCSI target.  Once you have this single system, you can leverage it for almost any network environment beyond a simple stand-alone system. Having these templates and fundamental infrastructure elements ready to run means I can build a quick lab in minutes instead of hours.  My solutions are well-tested, my processes fully documented with screenshots, and my plans validated well before I have to make any changes to client systems.  the work I put in is easily returned in increased value and client satisfaction.

Launchpad tells me that I have to some OpenPGP Fingerprint key, and I followed instructions from this link: https://launchpad.net/+help-registry/openpgp-keys.html#publish All goes fine, I enter all the necessary information, and it starts generating the key. After about 20 seconds of generating the key, it gives an error saying "Couldn't generate PGP key: General Error." What does this mean? How can I fix this?

  I want to make my application use dynamic unity quicklists. For building my application I am using C++ and the QtCreator IDE. When a menu action is triggered I want to be able to have access to a non-static function of my MainWindow class so as to be able to update the Graphical User Interface which can be accessed from inside 'normal' MainWindow's functions. So, I am building up my quicklist like this (mainwindow.cpp): void MainWindow::enable_unity_quicklist(){ Unity_Menu = dbusmenu_menuitem_new(); dbusmenu_menuitem_property_set_bool (Unity_Menu, DBUSMENU_MENUITEM_PROP_VISIBLE, FALSE); Unity_Stop = dbusmenu_menuitem_new(); dbusmenu_menuitem_property_set(Unity_Stop, DBUSMENU_MENUITEM_PROP_LABEL, "Stop"); dbusmenu_menuitem_child_append (Unity_Menu, Unity_Stop); g_signal_connect (Unity_Stop, DBUSMENU_MENUITEM_SIGNAL_ITEM_ACTIVATED, G_CALLBACK(&fake_callback), (gpointer)this); if(!unity_entry) unity_entry = unity_launcher_entry_get_for_desktop_id("myapp.desktop"); unity_launcher_entry_set_quicklist(unity_entry, Unity_Menu); dbusmenu_menuitem_property_set_bool(Unity_Menu, DBUSMENU_MENUITEM_PROP_VISIBLE, true); dbusmenu_menuitem_property_set_bool(Unity_Stop, DBUSMENU_MENUITEM_PROP_VISIBLE, true); } void MainWindow::fake_callback(gpointer data){ MainWindow* m = (MainWindow*)data; m->on_stopButton_clicked(); } void MainWindow::on_stopButton_clicked(){ //stopping the process... } mainwindow.h: private slots: void enable_unity_quicklist(); void on_stopButton_clicked(); public slots: static void fake_callback(gpointer data); This suggestion was taken from http://old.nabble.com/Using-g_signal_connect-in-class-td18461823.html The program crashes immediately after I choose the 'Stop' action from the Unity Quicklist. Debugging the program shows that I am not able to access anything MainWindow related inside the on_stopButton_clicked() without crashing. For example, it crashes when doing this check (which is the first 2 lines of code inside this function): if (!ui->stopButton->isEnabled()) return; I have also tested lots of other things that I found at the internet, but nothing of them worked. One interesting solution would be to use gtkmm (http://developer.gnome.org/gtkmm-tutorial/stable/sec-connecting-signal-handlers.html.en) but I am not used at all working on GTK applications (I work solely in Qt) and I don't know if this even suits to my occasion. A compilable example indicating what the problem is can be found at: http://ubuntuone.com/7iKA3wnPmWVp8YNNDLlVQI (3.2Kb) If you are not familiar with the QtCreator IDE, you can compile with the following commands, as long as you have all the needed libraries: cd dynamic_unity_quicklists_test; qmake -project; qmake; make

• OWB 11gR2 &ndash; OMB and File Editing

  - by David Allan

  Here we will see how we can use the IDE for editing OMB scripts. The 11gR2 release is based on the common Oracle platform IDE used also by JDeveloper. It comes with a bunch of standard behavior for editing and rendering code. One of the lesser known things is that if you drop a text file into OWB you can edit it. So you can drop your tcl scripts right into OWB and edit in-place, and don’t need another IDE like Eclipse just for this task. Cool, so you have the file here. There may be no line numbers, you can toggle line numbers on by right clicking in the gutter. If we edit the file within the OWB IDE, the save is a little different from normal. OWB doesn’t normally manipulate files so things like ctrl-s to save, saves the OWB objects, but if you edit a file the closing of the file will ask if you want to save it – check it out. Now we enter the realm of ‘he who dares’…. Note the IDE doesn’t know about tcl files out of the box, so you see above there is no syntax highlighting. The code is identified by the extension… .java is java, .html is HTML etc. With OWB, the OMB scripts are tcl, we usually have .tcl extension on these files. One of the things we can do to trick up the syntax highlighting is to simply rename the file to have a .java suffix, then all of a sudden we get syntax highlighting, see the illustration here where side by side we see a the file with a .java extension and a .tcl extension. Not ideal pretending to be .java but gets us a way to having something more useful than notepad. We can then change the syntax highlighting such that we get Eclipse like highlighting within the IDE from the Tools Preferences option; You then get the Eclipse like rendering albeit using a little tweak on the file names… Might be useful if you are doing any kind of heavy duty OMB script development and just want a single IDE. The OMBPlus panel is then at hand for executing and testing it out.

• last-modified/etags - to include or not?

  - by Kae Verens

  Google's PageSpeed plugin suggests that a website should include Last-Modified and ETag headers: Specify a cache validator "Resources that do not specify a cache validator cannot be refreshed efficiently. Specify a Last-Modified or ETag header to enable cache validation" However, Apache suggests that by not including them at all, we speed up websites by eliminating If-Modified-Since and If-None-Match requests: http://www.askapache.com/htaccess/apache-speed-last-modified.html these are in direct opposition - which should be implemented? I'm leaning towards Apache's suggestion, as when I want a file cached, I don't want it refreshed.

• Take advantage of the stimulus plan by hiring someone!

  - by Randy Walker

  In case you didn’t know, businesses can take advantage of the stimulus package by hiring an unemployed worker.  The Hiring Incentives to Restore Employment (HIRE) Act can pay the business portion of the Social Security taxes as well as give you a $1000 general business tax credit. If you’re unemployed, make sure and mention this to a potential employee! You can find out more information from here on Intuit’s website.  http://www.qbenews.com/QB_Payroll/1003_qbpb/landing_01.html

• Benefits of Behavior Driven Development

  - by Aligned

  Originally posted on: http://geekswithblogs.net/Aligned/archive/2013/07/26/benefits-of-behavior-driven-development.aspxContinuing my previous article on BDD, I wanted to point out some benefits of BDD and since BDD is an extension of Test Driven Development (TDD), you get those as well. I’ll add another article on some possible downsides of this approach. There are many articles about the benefits of TDD and they apply to BDD. I’ve pointed out some here and copied some of the main points for each article, but there are many more including the book The Art of Unit Testing by Roy Osherove. http://geekswithblogs.net/leesblog/archive/2008/04/30/the-benefits-of-test-driven-development.aspx (Lee Brandt) Stability Accountability Design Ability Separated Concerns Progress Indicator http://tddftw.com/benefits-of-tdd/ Help maintainers understand the intention behind the code Bring validation and proper data handling concerns to the forefront. Writing the tests first is fun. Better APIs come from writing testable code. TDD will make you a better developer. http://www.slideshare.net/dhelper/benefit-from-unit-testing-in-the-real-world (from Typemock). Take a look at the slides, especially the extra time required for TDD (slide 10) and the next one of the bugs avoided using TDD (slide 11). Less bugs (slide 11) about testing and development (13) Increase confidence in code (14) Fearlessly change your code (14) Document Requirements (14) also see http://visualstudiomagazine.com/articles/2013/06/01/roc-rocks.aspx Discover usability issues early (14) All these points and articles are great and there are many more. The following are my additions to the benefits of BDD from using it in real projects for my company. July 2013 on MSDN - Behavior-Driven Design with SpecFlow Scott Allen did a very informative TDD and MVC module, but to me he is doing BDDCompile and Execute Requirements in Microsoft .NET ~ Video from TechEd 2012 Communication I was working through a complicated task that the decision tree kept growing. After writing out the Given, When, Then of the scenario, I was able tell QA what I had worked through for their initial test cases. They were able to add from there. It is also useful to use this language with other developers, managers, or clients to help make informed decisions on if it meets the requirements or if it can simplified to save time (money). Thinking through solutions, before starting to code This was the biggest benefit to me. I like to jump into coding to figure out the problem. Many times I don't understand my path well enough and have to do some parts over. A past supervisor told me several times during reviews that I need to get better at seeing "the forest for the trees". When I sit down and write out the behavior that I need to implement, I force myself to think things out further and catch scenarios before they get to QA. A co-worker that is new to BDD and we’ve been using it in our new project for the last 6 months, said “It really clarifies things”. It took him awhile to understand it all, but now he’s seeing the value of this approach (yes there are some downsides, but that is a different issue). Developers’ Confidence This is huge for me. With tests in place, my confidence grows that I won’t break code that I’m not directly changing. In the past, I’ve worked on projects with out tests and we would frequently find regression bugs (or worse the users would find them). That isn’t fun. We don’t catch all problems with the tests, but when QA catches one, I can write a test to make sure it doesn’t happen again. It’s also good for Releasing code, telling your manager that it’s good to go. As time goes on and the code gets older, how confident are you that checking in code won’t break something somewhere else? Merging code - pre release confidence If you’re merging code a lot, it’s nice to have the tests to help ensure you didn’t merge incorrectly. Interrupted work I had a task that I started and planned out, then was interrupted for a month because of different priorities. When I started it up again, and un-shelved my changes, I had the BDD specs and it helped me remember what I had figured out and what was left to do. It would have much more difficult without the specs and tests. Testing and verifying complicated scenarios Sometimes in the UI there are scenarios that get tricky, because there are a lot of steps involved (click here to open the dialog, enter the information, make sure it’s valid, when I click cancel it should do {x}, when I click ok it should close and do {y}, then do this, etc….). With BDD I can avoid some of the mouse clicking define the scenarios and have them re-run quickly, without using a mouse. UI testing is still needed, but this helps a bunch. The same can be true for tricky server logic. Documentation of Assumptions and Specifications The BDD spec tests (Jasmine or SpecFlow or other tool) also work as documentation and show what the original developer was trying to accomplish. It’s not a different Word document, so developers will keep this up to date, instead of letting it become obsolete. What happens if you leave the project (consulting, new job, etc) with no specs or at the least good comments in the code? Sometimes I think of a new scenario, so I add a failing spec and continue in the same stream of thought (don’t forget it because it was on a piece of paper or in a notepad). Then later I can come back and handle it and have it documented. Jasmine tests and JavaScript –> help deal with the non-typed system I like JavaScript, but I also dislike working with JavaScript. I miss C# telling me if a property doesn’t actually exist at build time. I like the idea of TypeScript and hope to use it more in the future. I also use KnockoutJs, which has observables that need to be called with ending (), since the observable is a function. It’s hard to remember when to use () or not and the Jasmine specs/tests help ensure the correct usage.   This should give you an idea of the benefits that I see in using the BDD approach. I’m sure there are more. It talks a lot of practice, investment and experimentation to figure out how to approach this and to get comfortable with it. I agree with Scott Allen in the video I linked above “Remember that TDD can take some practice. So if you're not doing test-driven design right now? You can start and practice and get better. And you'll reach a point where you'll never want to get back.”

• Slow in the Application but Fast in SQL Server Management Studio - from Erland

  - by Greg Low

  Our MVP buddy Erland Sommarskog doesn't post articles that often but when he does, you should read them. His latest post is here: http://www.sommarskog.se/query-plan-mysteries.html It talks about why a query might be slow when sent from an application but fast when you execute it in SSMS. But it covers way more than that. There is a great deal of good info on how queries are executed and query plans generated. Highly recommended!...(read more)
