  • Smarty: Configurable Comments and Code Templates

    - by Martin Fousek
    Hello, today we would like to show you few improvements we have prepared in PHP Smarty Framework for NetBeans 7.3. So let's talk about adjustable toggle comment action and code templates. Configurable Comments As some of you requested we implemented toggle comment action with adjustable behavior. In NetBeans 7.3 you can choose in Options between commenting as a "Smarty comments everywhere" or "Language sensitive comments" in Smarty Templates. Toggle comment language sensitive: Toggle comment as Smarty comment everywhere: Code Templates In NetBeans 7.3 we will provide by default many code templates inside Smarty templates or directly inside Smarty tags. Available should be code templates for all built-in or custom functions and modifiers of Smarty 3.x. Besides that you should be able to define additional custom templates easily in Options -> Editor -> Code Templates for "Smarty Templates" or directly for "Smarty Markup" (which means code templates inside Smarty tag). You can also take advantage of selection's template which are able to wrap your code with chosen Smarty tag. That's all for today. As always, please test it and report all the issues or enhancements you find in NetBeans BugZilla (component php, subcomponent Smarty).

  • Branded Application Pages (layouts pages) in SharePoint 2010

    - by Sahil Malik
    Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). Application pages are now branded by default in SharePoint 2010. WOOHOO!!! The DynamicMasterPageFile attribute in SharePoint 2010 master pages allows application pages start using the site’s master page instead of the application master page. If you want backwards compatibility with SharePoint 2007, i.e. you want unbranded application pages, here is what you can do, a) You can change the MasterPageReferenceEnabled property to false in your SPWebApplication object, orb) Go to central administration\application management\manage web application\select your web app … go to the ribbon, look for general settings\general settings, and detach application pages from the site’s master page. I don’t see why you’d ever wanna do that, but hey if you want to .. go for it. This article was first published on blah.winsmarts.com. Stealing content is not cool. Safeguarded application pages Now for the fine print, there is something called as “Safeguarded application pages” in SP2010. These are pages, that IF IN CASE your custom master page screws up, they will automatically revert to use a master page that is guaranteed to work in the _layouts folder. Now that’s nice! That means, if you screw up, you always have a way to fix things. How nice! Here is a list of such safe guarded application pages - AccessDenied.aspx MngSiteAdmin.aspx People.aspx RecycleBin.aspx ReGhost.aspx ReqAcc.aspx Settings.aspx UserDisp.aspx ViewLsts.aspx Have fun!

  • Does DirectX implement Triple Buffering?

    - by Asik
    As AnandTech put it best in this 2009 article: In render ahead, frames cannot be dropped. This means that when the queue is full, what is displayed can have a lot more lag. Microsoft doesn't implement triple buffering in DirectX, they implement render ahead (from 0 to 8 frames with 3 being the default). The major difference in the technique we've described here is the ability to drop frames when they are outdated. Render ahead forces older frames to be displayed. Queues can help smoothness and stuttering as a few really quick frames followed by a slow frame end up being evened out and spread over more frames. But the price you pay is in lag (the more frames in the queue, the longer it takes to empty the queue and the older the frames are that are displayed). As I understand it, DirectX "Swap Chain" is merely a render ahead queue, i.e. buffers cannot be dropped; the longer the chain, the greater the input latency. At the same time, I find it hard to believe that the most widely used graphics API would not implement such fundamental functionality correctly. Is there a way to get proper triple buffered vertical synchronisation in DirectX?

  • PCI compliance when using third-party processing

    - by Moses
    My company is outsourcing the development of our new e-commerce site to a third party web development company. The way they set up our site to handle transactions is by having the user enter the necessary payment info, then passing that data to a third party merchant that processes the payment, then completing the transaction if everything is good. When the issue of PCI/DSS compliance was raised, they said: You wont need PCI certification because the clients browser will send the sensitive information directly to the third party merchant when the transaction is processed. However, the process will be transparent to the user because all interface and displays are controlled by us. The only server required to be compliant is the third party merchant's because no sensitive card data ever touches your server or web app. Even though I very much so trust and respect the knowledge of our web developers, what they are saying is raising some serious red flags for me. The way the site is described, I am sure we will not be using a hosted payment page like PayPal or Google Checkout offers (how could we maintain control over UI if we were?) And while my knowledge of e-commerce is laughable at best, it seems like the only other option for us would be to use XML direct to communicate with our third party merchant for processing. My two questions are as follows: Based off everything you've read, is "XML Direct" the only option they could conceivably be using, or is there another method I don't know of which they could be implementing? Most importantly, is it true our site does not need PCI certification? As I understand it, using the XML direct method means that we do have to be PCI/DSS certified, and the only way around getting certified is through a payment hosted page (i.e. PayPal).

  • How can I convert the Nvidia driver installer into a deb?

    - by Oli
    Every so often there's a beta version of the Nvidia driver that I want to try out. This has happened today: there's been a big performance issue with version 295.40 and I want to try the shiny new XRandR-enabled 302.07. I'm more than able to download the installer, remove all the repo-installed driver files and install the new version but it's frankly a pain in the bottom to turn that around and go back to the repo version. It also means I have to re-install the driver manually each time there's a Kernel upgrade. The other option we commonly give people is a PPA but in this case I'm being really impatient. It's going to be a few days before any PPA gets this but I need to try this today. I've already manually installed it on the media centre and I'm eyeing up my desktop now. So how do I take an installer (eg: NVIDIA-Linux-x86-302.07.run) and convert that into a new nvidia-current/nvidia-current-updates package? Another way of asking this might be: How do people package the Nvidia drivers?

  • JDK 7 Feature Complete Milestone Reached

    - by Henrik Ståhl
    The JDK 7 project has reached Feature Complete (FC). This means that development and QA have finished all planned feature and test development work in the release and are moving the focus to testing and bug fixing on all supported JDK 7 platforms. This is a major step towards JDK 7 General Availability (GA) and implies that we are tracking close to the plan published on openjdk.java.net. (The original plan was FC on 12/16. We hit this less than a week late, but verifying that everything was done in time took a couple of weeks due to the intervening holidays.) The definition of the FC milestone allows for exceptions to be integrated later. There are very few such exceptions in the project, the most prominent being updated JAXP/JAXB/JAX-WS and integration of the enhanced JMX agent from JRockit. Our project management does not expect the exceptions to have any negative impact on the release plan. The project may still be delayed if the Expert Groups for the JSRs included in Java SE 7 (203, 292, 334, 336) decide to introduce changes which cannot be accomodated within the existing schedule. Apart from that caveat, Oracle remains confident with the published plan.

  • Is there a SUPPORTED way to run .NET 4.0 applications natively on a Mac?

    - by Dan
    What, if any, are the (Microsoft) supported options for running C#/.NET 4.0 code natively on the Mac? Yes, I know about Mono, but among other things, it lags Microsoft. And Silverlight only works in a web browser. A VMWare-type solution won't cut it either. Here's the subjective part (and might get this closed): is there any semi-authoritative answer to why Microsoft just doesn't support .NET on the Mac itself? It would seem like they could Silverlight and/or buy Mono and quickly be there. No need for native Visual Studio; cross-compiling and remote debugging is fine. The reason is that where I work there is a growing amount of Uncertainty about the future which is causing a lot more development to be done in C++ instead of C#; brand new projects are chosing to use C++. Nobody wants to tell management 18–24 months from now "sorry" should the Mac (or iPad) become a requirement. C++ is seen as the safer option, even if it (arguably) means a loss in productivity today.

  • Google music search: a better way to listen.

    - by anirudha
    somebody who want to listen music  pay much more to some online music store for online listening. otherwise they experience bad or low quality on YouTube. who is illegal  because uploader not have a permission or right to upload the document and their is no guarantee that they not put their ads or quality as same. now forget YouTube and all other because Google music search is much better just go their search the song by movies name or song and just click and listen. the quality is much better then other but it is not Google. the result they put comes from other website. i feel a thing goes wrong in Google music  search  that if i search “sajda” they never show me result about “sadka” because the word in common life use as same both. but the song may be starting from  “sajda” or “sadka”. i thing that they put the link that Do you means “Sadka” when i search sajda that it is better thing just like many online book store show the different keyword related to your keyword when you search their. like you search for a book on online book store they show you some different keyword when they serve the result and show related product or books when you go to a product page. after thinking all it is a better option for user to feel a better quality music without search hassle.

  • Why is it that software is still easily pirated today?

    - by mohabitar
    I've always been curious about this. Now I wouldn't call myself a programmer yet, but I'm learning, so maybe the answer to this is obvious. It just seems a little hard to believe that with all of our technological advances and the billions of dollars spent on engineering the most unbelievable and mind-blowing software, we still have no other means of protecting against piracy then a "serial number/activation key". I'm sure a ton of money, maybe even billions, went into creating Windows 7 or Office and even Snow Leopard, yet I can get it for free in less than 20 minutes. Same for all of Adobe's products, which are probably the easiest. I guess my question is: can there exist a fool proof and hack proof method of protecting your software against piracy? If not realistically, how about theoretically possible? Or no matter what mechanisms these companies deploy, hackers can always find a way around it? EDIT: So apparently, the answer is no. There's pretty much no way. And so I'm sure these big companies have realized this as well. Should they adopt another sales model rather than charging a crapload for their software (I know its justified and they put a lot of hard work into their software, but its still a lot of money). Are there any alternative solutions that will benefit both the company and the user (i.e. if you purchase our product, we'll apply $X dollars to your account that will apply to future purchases from our company)?

  • Effective versus efficient code

    - by Todd Williamson
    TL;DR: Quick and dirty code, or "correct" (insert your definition of this term) code? There is often a tension between "efficient" and "effective" in software development. "Efficient" often means code that is "correct" from the point of view of adhering to standards, using widely-accepted patterns/approaches for structures, regardless of project size, budget, etc. "Effective" is not about being "right", but about getting things done. This often results in code that falls outside the bounds of commonly accepted "correct" standards, usage, etc. Usually the people paying for the development effort have dictated ahead of time what it is that they value more. An organization that lives in a technical space will tend towards the efficient end, others will tend towards the effective. Developers often refuse to compromise their favored approach for the other. In my own experience I have found that people with formal education in software development tend towards the Efficient camp. Those that picked up software development more or less as a tool to get things done tend towards the Effective camp. These camps don't get along very well. When managing a team of developers who are not all in one camp it is challenging. In your own experience, which camp do you land in, and do you find yourself having to justify your approach to others? To management? To other developers?

  • OSB and Ubuntu 10.04 - Too Many Open Files

    - by jeff.x.davies
    When installing the latest Oracle Service Bus (11gR1PS3) onto my Ubuntu 10.04 system, the Eclipse IDE was complaining about there being too many open files. The Oracle Service Bus and the Oracle Enterprise Pack for Eclipse (aka OEPE) do make use of ALOT of files. By default, Ubuntu will restrict each user to 1024 open files. A much more realistic number for OSB development is 4096. Changing the file limit in Ubuntu is fairly simple (if arcane). You will need to modify two different files and then restart your server. First, you need to modify the limits.conf file as the root user. Open a terminal window and enter the following command: sudo gedit /etc/security/limits.conf Add the following 2 lines to the file. The asterisk simply means that the rule will apply to all users. * soft nofile 4096 * hard nofile 4096 Save your changes and close gedit. The second file to change is the common-session file. Use the following command: sudo gedit /etc/pam.d/common-session Add the following line: session required pam_limits.so Save the file and exit gedit. Restart your machine. You shouldn't have any more problems with too many open files anymore.

  • Magento 1.6.2 Catalog Price Rule Problem

    - by robgt
    My Magento system seems to have a slight issue with Catalog Price Rule application. As far as the customer is concerned, all is working perfectly. The problem is that some orders are not being displayed properly in the admin system when I look at the details. The Catalog Price rule appears to not be applied - so when we reconcile our card processor details with those in our backend Sage system, numbers are not tallying up. Magento and out Sage system say the customer paid X, but the card issuer has taken payment of Y. The payment amount is correct due to the Catalog Price Rule. The customer is always paying the correct amount, but because of some issue with Magento, I think the data is possibly not being stored correctly (stored without the catalog price rule discount amount applied). This means that when I look at an order in the admin system, the line item prices that should be affected by the catalog price rule are not - but also the prices in our backend Sage system are incorrect too. We use another piece of software to bring the data into Sage from Magento, so the data must be stored in Magento's database incorrectly somewhere as this software reads out the order information from Magento. Does anyone have any idea what is wrong here, and how it might be fixed? Cheers!

  • What is the proper SEO handling of pages appearing in popups using IFRAMEs?

    - by Alexis Wilke
    I am working on a CMS which makes use of IFRAMEs to display some forms, for illustration, say a Search form. So the user clicks the Search button and the website reacts by opening a popup window which includes an IFRAME to the actual Search form. This means I have a "bare"¹ page with the search form. Page which, obviously, is directly accessible via its own URI. In terms of SEO, the forms have no content worthy of being indexed, so I was thinking to mark them as NOINDEX. Is that the correct way to handle such pages? From what I read on some other question, Google suggests to put links from IFRAMEs to other pages. However, I definitively do not want a user visible link to the Home page, or whatever page in link with the form, in the content of my forms because that could be misinterpreted by the user. However, if <link> tags would work too, which one should I use? (i.e. "top" would work, right? with the home page in there?) ¹ By bare I mean that the normal theme is not show, it will be a plain white background with just and only the simplest form.

  • Koans, now available in Python flavor

    - by Greg Malcolm
    Recently a Python developer friend with whom I was pair programming with suggested that I show him how to write a little Ruby. I responded by telling him to check out Ruby Koans as a starting point. However I wanted to try that in reverse at the same time with me learning some Python. I did a bit of googling, and sure enough someone had started writing some Python Koans. It just needed finishing... So, a few weeks later Python Koans is now complete and ready for action! It is available through Mercurial on Bitbucket: http://bitbucket.org/gregmalcolm/python_koans/wiki/Home It is also mirrored on Github: http://wiki.github.com/gregmalcolm/python_koans/ Converting it was fairly easy. Aside from the differing philosophical approaches behind the two languages, Ruby and Python are fairly similar. We had to come up with completely new material for a few subjects like multiple inheritance and decorators, but for most features in Ruby there is something roughly comparable in Python. I highly recommend writing tests (or koans) as a means to lean a new language or framework. I've learned a lot from doing this.

  • What is Cloud Computing?

    - by joelvarty
    This is a question that we discuss quite often at Edentity.  It’s one of those things, kind of like “web services” where the terminology has been thrown around by a ton of people and means a lot of different things. Here’s my favorite diagram so far, which is a visual breakdown of the material presented here by NIST, visualized by the folks at Cloud Security Alliance.     What I like about this diagram is that is shows several different ways that we can differentiate our definitions of cloud computing, from the essential characteristics, or which “Broad Network Access" and “On-Demand Self-Service” (which often are used on their own to define cloud computing) are but a couple of things that help make something “cloud”. The most important section from my point of view is the middle one – the Service Models.  This represents the different ways that cloud computing can be exposed from the ground up.  It can be an Infrastructure, a Platform or a piece of Software that an end user interacts with. This is the future, folks. more late - joel

  • Managing Social Relationships for the Enterprise – Part 1

    - by Michael Hylton
    By Reggie Bradford, Senior Vice President, Oracle  Today, Mark Hurd, President of Oracle, Thomas Kurian, Executive Vice President of Oracle and I discussed the strategic importance of how social media is impacting the enterprise and how it is changing the way customers, prospects employees and investors interact with brands worldwide.  Oracle understands that the consumer is in control and as such, brands must evolve and change to meet growing needs. In addition, according to social media thought leader and Analyst from Altimeter Group, Jeremiah Owyang, companies now average 178 corporate-owned social media accounts. When Oracle added leading social marketing, listening analytics and development tools from Vitrue, Collective Intellect and Involver to its Oracle’s Cloud Services Suite we went beyond providing a single set of tools. We developed an entire framework to include a comprehensive social relationship management suite to help companies move beyond the social enterprise and achieve the social-enabled enterprise.  The fundamental shift from transaction to engagement means that enterprises need not only a social strategy, but should also ensure that the information and data received from social initiatives flow back to marketing, sales, support and service. Doing so enables companies to deliver a proactive and compelling experience and provides analytics to turn engagement into opportunity – and ultimately that opportunity into revenue.  On September 13, 2012, I am delighted to sit down with Jeremiah to further the discussion about how enterprises are addressing social media strategies and managing content.  In addition, we will be taking your questions after the webinar via Twitter (@Oracle, @ReggieBradford, @cfinn, @jowyang). Use #oracle and #socbiz to submit questions and follow the conversation. I look forward to speaking with you and answering your questions online.  For more information about becoming a social-enabled enterprise, visit www.oracle.com/social. And don’t miss the insights of other social business thought leaders at www.oracle.com/goto/socialbusiness.

  • Architecture Standards &ndash; BPMN vs. BPEL for Business Process Management

    - by pat.shepherd
    I get asked often which business process standard an organization should use; BPMN or BPEL?  As I explain to folks, they both have strengths.  Here is a great article that helps understand the benefits of both and where to use them.  The good news is that, with Oracle SOA Suite and BPM suite, you have the option and flexibility to use both in the same SCA model and runtime container.  Good stuff. Here is the great article that Mark Nelson wrote: The right tool for the right job BPEL and BPMN are both ‘languages’ or ‘notations’ for describing and executing business processes. Both are open standards. Most business process engines will support one or the other of these languages. Oracle however has chosen to support both and treat them as equals. This means that you have the freedom to choose which language to use on a process by process basis. And you can freely mix and match, even within a single composite. (A composite is the deployment unit in an SCA environment.) So why support both? Well it turns out that BPEL is really well suited to modeling some kinds of processes and BPMN is really well suited to modeling other kinds of processes. Of course there is a pretty significant overlap where either will do a great job What BPM adds to SOA Suite | RedStack

  • Syntax logic suggestions

    - by Anna
    This syntax will be used inside HTML attributes. Here are a few examples of what I have so far: <input name="a" conditions="!b, c" /> <input name="b" /> <input name="c" /> This will make input "a" do something if b is not checked and c is checked (b and c are assumed to be checkboxes if they don't have a :value defined) <input name="a" conditions="!b:foo|bar, c:foo" /> <input name="b" /> <input name="c" /> This will make input "a" do something if bdoesn't have foo or bar values, and if c has the foo value. <input name="a" conditions="!b:EMPTY" /> <input name="b" /> Makes input "a" do something if b has a value assigned. So, essentially , acts as logical AND, : as equals (=), ! as NOT, and | as OR. The | (OR) is only needed between values (at least I think so), and AND is not needed between values for obvious reasons :) EMPTY means empty value, like <input value="" /> Do you have any suggestions on improving this syntax, like making it more human friendly? For example I think the "EMPTY" keyword is not really appropriate and should be replaced with a character, but I don't know which one to choose.

  • Search SSIS packages for table/column references

    - by Nigel Rivett
    A lot of companies now use TFS or some other system and keep all their packages in a single project. This means that a copy of all the packages will end up on your local disk. There is major failing with SSIS that it is sometimes quite difficult to find what a package is actually doing, what it accesses and what it affects. This is a simple dos script which will search through all packages in a folder for a string and write the names of found packages to an output file. Just copy the text to a .bat file (I use aaSearch.bat) in the folder with all the package scripts Change the output filename (twice), change the find string value and run it in a dos window. It works on any text file type so you can also search store procedure scripts – but there are easier ways of doing that. echo. > aaSearch_factSales.txt for /f “delims=” %%a in (‘dir /B /s *.dtsx’) do call :subr “%%a” goto:EOF :subr findstr “factSales” %1 if %ERRORLEVEL% NEQ 1 echo %1 >> aaSearch_factSales.txt goto:EOF

  • How to determine where on a path my object will be at a given point in time?

    - by Dave
    I have map and an obj that is meant to move from start to end in X amount of time. The movements are all straight lines, as curves are beyond my ability at the moment. So I am trying to get the object to move from these points, but along the way there are way points which keep it on a given path. The speed of the object is determined by how long it will take to get from start to end (based on X). This is what i have so far: //get_now() returns seconds since epoch var timepassed = get_now() - myObj[id].start; //seconds since epoch for departure var timeleft = myObj[id].end - get_now(); //seconds since epoch for arrival var journey_time = 60; //this means 60 minutes total journey time var array = [[650,250]]; //way points along the straight paths if(step == 0 || step =< array.length){ var destinationx = array[step][0]; var destinationy = array[step][1]; }else if( step == array.length){ var destinationx = 250; var destinationy = 100; } else { var destinationx = myObj[id].startx; var destinationy = myObj[id].starty; } step++; When the user logs in at any given time, the object needs to be drawn in the correct place of the path, almost as if its been travelling along the path whilst the user has not been at the PC with the available information i have above. How do I do this? Note: The camera angle in the game is a birds eye view so its a straight forward X:Y rather than isometric angles.

  • How can I make sense of the word "Functor" from a semantic standpoint?

    - by guillaume31
    When facing new programming jargon words, I first try to reason about them from an semantic and etymological standpoint when possible (that is, when they aren't obscure acronyms). For instance, you can get the beginning of a hint of what things like Polymorphism or even Monad are about with the help of a little Greek/Latin. At the very least, once you've learned the concept, the word itself appears to go along with it well. I guess that's part of why we name things names, to make mental representations and associations more fluent. I found Functor to be a tougher nut to crack. Not so much the C++ meaning -- an object that acts (-or) as a function (funct-), but the various functional meanings (in ML, Haskell) definitely left me puzzled. From the (mathematics) Functor Wikipedia article, it seems the word was borrowed from linguistics. I think I get what a "function word" or "functor" means in that context - a word that "makes function" as opposed to a word that "makes sense". But I can't really relate that to the notion of Functor in category theory, let alone functional programming. I imagined a Functor to be something that creates functions, or behaves like a function, or short for "functional constructor", but none of those seems to fit... How do experienced functional programmers reason about this ? Do they just need any label to put in front of a concept and be fine with it ? Generally speaking, isn't it partly why advanced functional programming is hard to grasp for mere mortals compared to, say, OO -- very abstract in that you can't relate it to anything familiar ? Note that I don't need a definition of Functor, only an explanation that would allow me to relate it to something more tangible, if there is any.

  • What causes critical glib errors (when coding using messaging menu)?

    - by fluteflute
    If I run the python code below (almost entirely from this useful blog post) then I get three identical nasty looking error messages in the terminal. What might be causing them? I note the number (5857 in the example below) changes slightly on each run. What does this number signify? Is it a memory location or something similar? (messaging-menu.py:5857): GLib-GIO-CRITICAL **: g_dbus_method_invocation_return_dbus_error: assertion `error_name != NULL && g_dbus_is_name (error_name)' failed (messaging-menu.py:5857): GLib-GIO-CRITICAL **: g_dbus_method_invocation_return_dbus_error: assertion `error_name != NULL && g_dbus_is_name (error_name)' failed (messaging-menu.py:5857): GLib-GIO-CRITICAL **: g_dbus_method_invocation_return_dbus_error: assertion `error_name != NULL && g_dbus_is_name (error_name)' failed I'm running this on Natty, I should probably find out if I get the same errors in 10.10 though... import gtk def show_window_function(x, y): print x print y # get the indicate module, which does all the work import indicate # Create a server item mm = indicate.indicate_server_ref_default() # If someone clicks your server item in the MM, fire the server-display signal mm.connect("server-display", show_window_function) # Set the type of messages that your item uses.

(You can't set both.) This means that instead of a # message count, the MM will show "2m" or similar for the time since this # message arrived. # mm_source.set_property_time("time", time.time()) mm_source.show() gtk.main()
