• Google's Opinion on Javascript Page Refresh

  - by user35306

  I was wondering if anyone knows Google's view on this. My company has a homepage that features a lot of 3rd parties on it and it needs to inform customers which ones are currently online, which aren't, and which are currently busy. Because this constantly changes, we have the homepage refresh to show the most relevant and up-to-date content to our users. I'm not using a meta refresh element in the http-equiv parameter to do this. Instead I have this js element to refresh the page: window.setTimeout("refreshPage()", 120000); I just want to know whether people think Google might consider this a violation of the content guidelines or not. Or if it's not an outright violation, then at least if Google frowns on this or not. It doesn't redirect the user to a different page or anything, just refreshes the page so that they can see the most relevant content.

• Does my JavaScript look big in this?

  - by benhowdle89

  As programmers, you have certain curtains to hide behind with your code. With PHP all of your code is server side preprocessed, so this never see's the light of day as far as the user is concerned. If you have maybe rushed through some code for a deadline, as long as it functions correctly then the user never needs to know how many expletives you've inserted into the comments. However with more and more applications being written for the web, with a desktop feel implemented by AJAX and popular frameworks like jQuery being banded around to every Tom, Dick and Harry, how can a programmer maintain some dignity and hide his/her JavaScript code without it being flaunted like dirty laundry when the users hit Right Click-View Source or Inspect Element. Are there any ways to hide JavaScript application logic/code?

• How to change sample text in font installer

  - by Tony Martin

  I have several Japanese fonts but do not want to install them all. I would like to preview them before installing. In icon view I can get a very rough idea of the style of the font as it shows Aa. When I open the font I am presented with a dialog box which shows a sample of the font with the sentence The quick brown fox jumped over the lazy dog. I would like to change this sample text to Japanese text to get a fuller preview of the font. Is it at all possible? I suspect I might have to edit and compile source, not something I'm very familiar with.

• Attached Property port of my Window Close Behavior

  - by Reed

  Nishant Sivakumar just posted a nice article on The Code Project.  It is a port of the MVVM-friendly Blend Behavior I wrote about in a previous article to WPF using Attached Properties. While similar to the WindowCloseBehavior code I posted on the Expression Code Gallery, Nishant Sivakumar’s version works in WPF without taking a dependency on the Expression Blend SDK. I highly recommend reading this article: Handling a Window’s Closed and Closing Events in the View-Model.  It is a very nice alternative approach to this common problem in MVVM.

• Determine corners of a specific plane in the frustum

  - by Takumi

  I'm working on a game with a 2D view in a 3D world. It's a kind of shoot'em up. I've a spaceship at the center of the screen and i want that ennemies appear at the borders of my window. Now i don't know how to determine positions of the borders of the window. For example, my camera is at (0,0,0) and looking forward (0,0,1). I set my spaceship at (0,0,50). I also know the near plane (1) and the far plane(1000). I think i'd have to find the 4 corners of the plane in the frustum whose z position is 50, and with these corner i can determine borders. But i don't know how to determine x and y.

• What is the best idea to put available OS (linux) and Web application to client?

  - by Fernando Costa

  After a year programming a web based business management system, I got my idea divided into two differents ways to do what I'm doing... I will try to explain in follow lines: First I will describe my enviroment: Webserver: apache, ngynx Programming Language: PHP, Shell Script, Java Script, SQL Database: Mysql Operating System: Linux, UNIX (All Distros) (If manually configured works on windows) Authentication Server: FreeRadius First situation I have my application running on this enviroment that I had just described before, as my application is a SaaS app, then I have my own server to run it all and customers pay to use it as a service accessed by webbrowser. Second Situation The same as before but with one big difference, everything (environment) is installed in the customer, then I need to cryptography all my codes (It includes PHP and Shell Scripts). I think this situation is most difficulty, but I would like to hear it from different points of view.

• Programming for the iPhone

  - by Bobby Alexander

  Whats the best way to get started on iPhone development if you are an expeienced C++ or C# programmer? Most books either assume you know nothing or something. What are the steps to achieve this? For eg: first learn objective C (let's say), next learn cocoa... I am interested in books/resources. I read Getting started with iPhone development from Oreilly (the missing manuals book) but that just provided an over view on the programming and concentrated more on getting your app into the app store. I need need resources that will help be start coding. Other questions: How much of objective C do you need to know? How do go ahead with learning the cocoa framework? Can I directly start on cocoa touch or do I need to know the MAC cocoa framework first? Inputs from someone who was in the same situation (Know c++/c# but no clue about mac programming/objective c/cocoa) would help greatly.

• Scrolling Box2D DebugDraw

  - by onedayitwillmake

  I'm developing a game using Box2D (javascript implementation - Box2DWeb), and I would like to know how I can pan the debug draw. I know the usual answer is - don't use debug draw, it's just for debugging. I'm not, however not all my objects are on the same screen, and i'd like to see where they are in the physics representation. How can I pan the debug drawing? As you can see the debug draw stuff, is show on the top left, but it only shows a small part of the world. Here is an example of what I mean: http://onedayitwillmake.com/ChuClone/ The game is open source, If you'd like to poke through and note something that perhaps i'm doing something that is obviously wrong: https://github.com/onedayitwillmake/ChuClone Here's my hacky way that I'm using now to scroll the b2DebugDraw view, in which I added a property offsetX and offsetY into b2DebugDraw

• Functional Programming - Does Knowing It Help Job Prospects?

  - by Jetti

  The main language that I use at the moment is C# and I am the most comfortable with it. However, I have started dabbling in F# and Haskell and really enjoy those langauges. I would love to improve my skills in either of those languages over time since it truly is fun for me to use them (as opposed to Ruby, which is hyped as "fun", I just don't get where the fun is, but I digress...). My question is directed at those who have hired/interviewed for programming positions (junior/mid-level): if you see a functional programming language on a resume, does it affect your opinion (whether positive or negatively) of that candidate? My rationale for knowledge of functional programming affecting the view of a candidate is because it can show that the candidate can adapt to different methodologies and take a mulit-dimensional approach to problems rather than the "same old OO approach". (This may be off-base, please let me know if this assumption is as well!)

• URL structure for content that is updated daily

  - by Brendon

  A small, simple site I am working on displays a single page with the day's best offers on it. The user is able to move back and forth between previous days. Which of the following URL structures works best? Structure 1 /index.html -- today's best offers /2013-06-29.html -- yesterday's best offers, etc. Structure 2 /index.html -- 302 redirects to /2013-06-30.html (or whatever today is) /2013-06-30.html -- today's best offers /2013-06-29.html -- yesterday's best offers, etc. I quite like structure 2 from the user's point of view (they can share content easily), but I am a bit concerned about updating the redirect from /index.html every single day -- would this perhaps have unintended SEO consequences?

• How To Use Flash on Any Website in Modern Internet Explorer 10

  - by Chris Hoffman

  The modern (or “Metro”) version of Internet Explorer in Windows 8 supports Flash, but only for some Microsoft-approved websites. You can add your own favorite websites to Microsoft’s whitelist to view Flash on any website. The desktop version of IE supports Flash on every website, but you don’t have to leave the new Windows 8 user interface if you don’t want to. This trick works on both Windows 8 and Windows RT.

• How do you track bugs in your personal projects?

  - by bedwyr

  I'm trying to decide if I need to reassess my defect-tracking process for my home-grown projects. For the last several years, I really just track defects using TODO tags in the code, and keeping track of them in a specific view (I use Eclipse, which has a decent tagging system). Unfortunately, I'm starting to wonder if this system is unsustainable. The defects I find are typically associated with a snippet of code I'm working on; bugs which are not immediately understood tend to be forgotten, or ignored. I wrote an application for my wife which has had a severe defect for almost 9 months, and I keep forgetting to fix it. What mechanism do you use to track defects in your personal projects? Do you have a specific system, or a process for prioritizing and managing them?

• Issues with the intended behavior of a Service layer?

  - by Rafael Cichocki

  This analysis makes sense, and states anything that avoids code duplication and simplifies maintenance speaks for a service layer. What is the technical behavior? When a service client references a service, does it do so at runtime, or does it happen at compile time? When I change something in the service layer code, will this change be automatically taken into account in all it's clients, or do they need to be individually recompiled? How does this make sense from a testing point of view - I have working code, based on some code from a service, but if that service changes, my code might break?!

• Inspecting the model in a Rails application

  - by Matt Sherman

  I am learning some Ruby on Rails, and am a newbie. Most of my background is in ASP.net MVC on the back end. As I play with a basic scaffold project, I wonder about this case: you jump into an established Rails project and want to get to know the model. Based on what I have seen so far (again, simple scaffold), the properties for a given class are not immediately revealed. I don't see property accessors on the model classes. I do understand that this is because of the dynamic nature of Ruby and such things are not necessary or even perhaps desirable. Convention over code, I get that. (Am familiar with dynamic concepts, mostly via JS.) But if I am somewhere off in a view, and want to quickly know whether the (eg) Person object has a MiddleName property, how would I find that out? I don't have to go into the migrations, do I?

• Saving an interface instance into a Bundle

  - by user22241

  All I've have an interface that allows me to switch between different scenes in my Android game. When the home key is pressed, I am saving all of my states (score, sprite positions etc) into a Bundle. When re-launching, I am restoring all my states and all is OK - however, I can't figure out how to save my 'Scene', thus when I return, it always starts at the default screen which is the 'Main Menu'. How would I go about saving my 'Scene' (into a Bundle)? Code import android.view.MotionEvent; public interface Scene{ void render(); void updateLogic(); boolean onTouchEvent(MotionEvent event); } I assume the interface is the relevant piece of code which is why I've posted that snippet. I set my scene like so: ('options' is an object of my Options class which extends MainMenu (Another custom class) which, in turn implements the interface 'Scene') SceneManager.getInstance().setCurrentScene(options); //Current scene is optionscreen

• Which hosted chat solutions offer the following?

  - by David

  I am looking for a chat room solution similar to the one on StackExchange to facilitate more responsive communication between the contributors on Open-Org.com. My criteria are the following: No Flash (this rules out more than half) Full history (meaning that it is possible to access all previous conversation for future reference. Very customizable No ugly IRC stuff filling up the chat view (I do not want to see who joined an who left etc.) No private conversations possible (this is just not in the spirit of Open-org.com) A hosted solution with a reasonable price. These criteria are so different from this question, so this is not a duplicate question. The service which matches this the closest is Chatroll.com. However, at 199$ per month their prices are outrageous.

• Microsoft se défend des accusations de Google et dit "apprendre de ses consommateurs", Google persiste et dis n'avoir "jamais rien vu de pareil"

  Microsoft se défend des accusations de Google et dit "apprendre de ses consommateurs", Google persiste et dis n'avoir "jamais rien vu de pareil" Mise à jour du 02.02.2011 par Katleen Il y a quelques heures, de hauts responsables des moteurs de recherche en ligne étaient réunis lors d'une table ronde. D'un côté, Matt Cutts (Google) et de l'autre, Harry Shum (Bing). Le sujet des accusations de Mountain View portées hier envers Microsoft (lire news précédente) a évidement été abordé, et pas vraiment dans le calme. Il faut savoir que dans la nuit (heure française), Redmond avait publié un démenti assurant que jamais les résultats de son concurrents n'avaient été...

• When Googlebot sees a link, will it click it or navigate to it?

  - by FakeRainBrigand

  My site uses pushState and JSON data to display content. So, for example, this might appear on my page: <a href="/some/page">some page</a> The JavaScript then prevents the default action (following the link), and instead renders a view (using a different api, such as /getjson?some_page). $('[href]').click(function(){ history.pushState(...); handleURL(...); }); Assume my server will respond to requests at /some/page with a pre-rendered version. My questions are: will Googlebot receive the prerendered version, or allow JavaScript to instead invoke pushState, etc. if it doesn't make the direct request, will it wait for AJAX content to be loaded? does Googlebot implement pushState, so it will show the proper URL in search results?

• Could someone help me understand SQL TDE Database encryption?

  - by SLC

  I don't quite follow how it works. According to the MSDN Article there is a big hierarchy of keys protecting other keys and passwords. At some point the database is encrypted. You query the database which is encrypted, and it works seamlessly. If you're able to simply connect to the database as normal and not have to worry about any of the encryption from a developer point of view, how exactly is it secure? Surely anyone can simply connect and do select * from x and the data is revealed. Sorry my question is a bit scattered, I am just very confused by the article.
