• htaccess 301 redirect for payment page

  - by Chris Robinson

  I have a client who currently runs a venue and has ticket purchases made available through a third party. The way the site currently works is that there is a standard href in the nav menu to the ticket purchasing site. <a href'http://example.com/events'>Events</a> <a href'http://example.com/about'>About</a> <a href'https://someticketvendor.com/myclient?blah'>Tickets</a> They claim that they want to improve their SEO by appearing to integrate the ticket pages into their site. Having spoken to the ticket vendor, they only offer integration through iframes which is just horrible. I don't really know much about SEO but I'm wondering if I can create an htaccess rule to have http://example.com/tickets forward to href'https://someticketvendor.com/myclient?blah Are they are any negative SEO implications to doing this? Is there a better way this could be done?

• How to redirect user into mobile website?

  - by iLa

  Hi how to redirect the user into mobile site when the user accessing from mobile. Say example i have site called www.mysite.com. Now, a person accessing a website from mobile it should redirect to www.mysite.com/mobile or www.m.mysite.com. I put some research in google that we can redirect using javascript to get the user agent(browser) if(mobile browser) { //redirect to www.mysite.com/mobile } else if(normal browser) { //redirect to www.mysite.com } or using screen resolution if(screen resolution < 800 ) { //redirect to www.mysite.com/mobile } else if(screen resolution > 800) { //redirect to www.mysite.com } I think It will not work If it is the case of javascript disable. Can we do this using .htaccess or php stuff? Is there any standard mechanism to do this?

• Question about creating a sprite based 2-D Side Scroller with scaling/zooming

  - by Arthur

  I'm just wondering if anyone can offer any advice on how best to go about creating a 2-D game with zooming/scaling features akin to the early Samurai Showdown games. In this case it would be a side scroller a la Metal Slug, the zooming would come in as more enemy sprites entered the screen, or when facing a large sized boss. A feature that would be both cosmetic as well as functional to the game. I've done some reading and noticed a few suggestions that included drawing different sized sprites, a standard size and zoomed out size. Any thoughts? Thanks for your time.

• In Google Analytics, how can I determine the value of a page if no goals or revenue have been determined?

  - by Brandon Durham

  I have 4 years of data in Analytics with over 20 million pageviews for the entire site. No goals have ever been set up, and while the site is an ecommerce site, no ecommerce features in Google Analytics have ever been taken advantage of. So I have no way to determine what the actual value of a page is. I've been tasked with determining if a particular page on the site is worth keeping around. How might I use all standard data (pageviews, bounce rate, time on page, time on site, etc.) to help determine the value of this page? I really appreciate any help I can get!

• The rule of 5 - to use it or not?

  - by VJovic

  The rule of 3 (the rule of 5 in the new c++ standard) states : If you need to explicitly declare either the destructor, copy constructor or copy assignment operator yourself, you probably need to explicitly declare all three of them. But, on the other hand, the Martin's "Clean Code" advises to remove all empty constructors and destructors (page 293, G12:Clutter) : Of what use is a default constructor with no implementation? All it serves to do is clutter up the code with meaningless artifacts. So, how to handle these two opposite opinions? Should empty constructors/destructors really be implemented?

• Convincing Upper Management the need of larger monitors for Developers

  - by The Rubber Duck

  The company I work for has recently hired on several developers, and there are a limited number of monitors to go around. There are two types in the office - a standard 15" (thankfully flatscreen) and a widescreen 23". No developer has a machine capable of a dual monitor setup, and the largest monitors went to the people who got here first. Three or four new senior level developers only have a 15" monitor to work on. To make matters worse, there are perhaps a total of 25-30 DBAs/Testers/Admin types in the company who all have dual screen 23" setups. We have brought the issue to management, and they refuse to take away large monitors from people who have been here for years for the sake of new employees, even if they are senior level. We have pitched the idea of testers sacrificing a large monitor for one of our small ones, but they won't go for that either. What can I say to management to illustrate the need of monitors for developers?

• Calculating angle between 2 vectors

  - by Error 454

  I am working on some movement AI where there are no obstacles and movement is restricted to the XY plane. I am calculating 2 vectors: v - the direction of ship 1 w - the vector pointing from the position of ship 1 to ship 2 I am then calculating the angle between these two vectors using the standard formula: arccos( v . w / ( |v| |w| ) ) The problem I'm having is the nature of arccos only returning values between 0 and 180. This makes it impossible to determine whether I should turn left or right to face the other ship. Is there a better way to do this?

• Is "convention over configuration" not violating basic programming principles?

  - by Geerten

  I was looking at the WPF MVVM framework Caliburn.Micro and read that a lot of standard things are based on naming conventions. For example, automatic binding of properties in the View to properties in the ViewModel. Although this seems to be convenient (removes some boilerplate code), my first instinct reaction is that it isn't completely obvious to a new programmer that will read this code. In other words, the functionality of the application is not completely explained by its own code, but also by the documentation of the framework. EDIT: So this approach is called convention over configuration. Since I could not find any questions concerning this, I altered my question: My question is: Is convention over configuration a correct way of simplifying things, or is it violating some programming principles (and if so, which ones)?

• Why does the BADSIG/"Untrusted sources" error recur forever?

  - by Jeff McMahan

  On at least a dozen occasions, I've spent 2-3 hours figuring out how to get Ubuntu 11.10-12.10 to either update or acquire software from software center, or both. I want to fix whatever is causing the BADSIG problem once and for all; I've wasted so much time trying to get this to work well enough that I can rely on it, but the same problem comes back after a couple weeks of normal updates and software center usage. Don't refer me to a standard posted solution on the web---whatever it is, I've used it more times than you have. The question isn't whether I can get it to work right this afternoon. I can. The question is what is causing the problem to recur regularly across 3 releases. Notice: I use this computer 4-5 hours per week and I do little on it. PDFs, Latex, FireFox, Mendeley, and that's it. I don't constantly install new software, and I don't fiddle with things unnecessarily.

• Is it possible to develop apps with Kendo UI to submit to iOS App Store?

  - by Farshid

  The number of platforms I have to develops apps for is increasing and It brings me lots of stress to learn new technologies for each target platform. I found out that Telerik's Kendo UI is very good to build websites that look and feel native on mobile platforms (e.g. iOS and Android). My question is, is it possible to build HTML5 apps to deploy them on iTunes App Store and Google Play? Please note that I am eager to know the possibility of creating apps (complete apps bundled in standard format of Apple and Google for distribution in their respective mobile app markets) but not websites.

• How to find optimal path visit every node with parallel workers complicated by dynamic edge costs?

  - by Aaron Anodide

  Say you have an acyclic directed graph with weighted edges and create N workers. My goal is to calculate the optimal way those workers can traverse the entire graph in parralel. However, edge costs may change along the way. Example: A -1-> B A -2-> C B -3-> C (if A has already been visited) B -5-> C (if A has not already been visited) Does what I describe lend itself to a standard algorithmic approach, or alternately can someone suggest if I'm looking at this in an inherently flawed way (i have an intuition I might be)?

• How to make the apt autocompletion work in minimal system (in LXC container)?

  - by Adam Ryczkowski

  When I work inside thin LXC container on 12.04 I have only very basic system. In particular the /etc/bash_completion.d is missing the e.g. apt, that I find particularly useful. Is there any standard package, that installs the autocompletion for the apt, or should I copy the file manually? And just copying the files into /etc/bash_completion.d manually just doesn't seem to work. I use bash as my command interpreter. What am I missing here?

• T60 Screen/LCD gets black after some minutes with a highpitched sound rising and fading

  - by edelwater

  Just now my T60 screen got "black" (so no display). On my second monitor: no problems so the VGA output works. Symptom: Screen blanks / no display, but it works on the second monitor Steps to reproduce: - boot - wait (it does not matter what you do you do not have to login or anything) - (now the monitor of the laptop slowly begins to make a ssssssssHHHHHHHHHHHHHHHHHWOEOEssssssss noise of about 10 seconds) - right after the sounds ends, the monitor gets black. Sometimes it seems to be the same each time. Software: Installed no new software before/after, running ZoneAlarm and antivirus. Other: It does not feel hot in any place, there don't seem to be running processes with strange behaviour. Warranty: Out of warranty What was I doing: Typing text on a website and doing some PHP coding in a text editor. What can I do here other than buy a new laptop? Does it sound familiar to known cases? Update 1: Exactly the same problem: http://forums.lenovo.com/t5/T61-and-prior-T-series-ThinkPad/T60-Screen-Blackout/m-p/288772 and the second poster (garyj), http://forums.lenovo.com/t5/T61-and-prior-T-series-ThinkPad/Black-Screen-on-T60/m-p/235053#M48627 And here: "I have that same problem. I replaced the CCRL on mine and it works fine when the screen is not screwed in. Once the frame of the LCD screen (metal portion) touches the metal on the laptop which holds the screen the screen goes black. If the metal is touching the screen when you boot up it boots up with it being very dimmly lit. " from http://forums.lenovo.com/t5/T61-and-prior-T-series-ThinkPad/T60-screen-problems/m-p/205047#M44995 (it seems replacing the LCD display is no use, he tried it three times). Same problem: http://forums.lenovo.com/t5/T61-and-prior-T-series-ThinkPad/T60-black-screen/m-p/80604#M25914 Hmmm... not handy 3 or 4 months ago I ordered and installed a new fan. Now the LCD. Which does not seem the core issue but some electric issue so it seems replacing the LCD is not the thing to do here. If it is not the LCD that needs to be replaced (see other threads), which parts can I order to fix this? Is there any information which could lead me to identify the issue? I have read replacing the "inverter" AND the "backlightning" would that make sense? Update 2: I replaced the inverter with another inverter, but IO have the same problem. I DID notice that the inverter is the component that makes the sssssssssssssHHHHHHHHHH sound AND it becomes very hot in a few seconds. (So both the old and the test one) The problem is hmmm wat is then the thing that makes the inverter hot by (assumption) after which it shuts itself down. Is it either the input or the output? The output seems to me not, because the screen seems to function so it must be the electricity coming in. But what causes it to become so hot would it be the VGA card outputting some unusual high voltage seems unlikely? I am looking for the component to order / replace update 3: Great news. Ewendish gave me the hint to look in the BIOS. While I was in the BIOS I noticed that the screen did not switch off and there was not a high pitched sound. So I lowered some settings in the BIOS. I then noticed that with brightness turned to 0 (via FN End), it does not make a high pitched sound and does not turn off, with brightness turned up just three "stripes" it starts making the sound. So I could from now on work under lowest brightness modus or... see where the problem lies. So as stated below with either power management or display drivers / ATI Catalyst settings / Windows display settings. I'm trying to see where it lies, but I will google some first. Update 4: I wiped clean the Windows XP installation and installed Windows 7 on it. Unfortunately the problem remains: as soon as the brightness goes up the screen starts hissing. This means... back to original thought: it probably IS a hardware problem. Although ... again... if it is NOT the inverter, what is it? Could it be the backlightning component? I could try to switch that with a another T60... but this is quite tricky.

• How to find manually installed packages?

  - by queueoverflow

  I installed a plain Ubuntu 10.10 on my computer and installed some software via apt-get. Last week I managed to break everything and just started from scratch, and I need to reinstall my software. Is there some way to create a list with all the packages that I have installed manually? So that it would give me a list like „texlive, ...“ and not „texlive, texlive-dep1, textlive-dep2, ...“ and all the standard packages removed? If I could somehow figure out which programs out of the regular install I have removed, that would be awesome too!

• Using packages (gems, eggs, etc.) to create decoupled architectures

  - by Juan Carlos Coto

  The main issue Seeing the good support most modern programming platforms have for package management (think gem, npm, pip, etc), does it make sense to design an application or system be composed of internally developed packages, so as to promote and create a loosely coupled architecture? Example An example of this would be to create packages for database access, as well as for authentication and other components of the system. These, of course, use external packages as well. Then, your system imports and uses these packages - instead of including their code within its own code base. Considerations To me, it seems that this would promote code decoupling and help maintainability, almost in a Web-based-vs.-desktop-application kind of way (updates are applied almost automatically, single code base for single functionality, etc.). Does this seem like a rational and sane design concept? Is this actually used as a standard way of structuring applications today? Thanks very much!

• Is there a canonical source for learning C# and .NET internals?

  - by ta269uec

  I have been a C++ programmer for last several years with a bit of C# here and there. In my latest job, I work heavily on C#. I picked most of my C# by following the code-base or random google searches on what I wanted to do at that point (like threading in C#). I feel a time has come to invest some time into understanding the language internals and also understanding the .NET framework from an architectural point of view. Can someone recommend the "gold standard" text/resource for accomplishing these? What about that resource makes it the best? What were your experiences with it?

• Magento not responding to payment gateway notifications fast enough or at all?

  - by robgt

  Some of our customers are getting to the confirmation of payment step in purchasing from our Magento store, and then they are getting a timeout error, where the SagePay payment gateway is trying to contact our server to tell it that a payment was successful (or not…) but it cannot contact our server, or cannot get a response from our server in a timely manner, and then the payment/order is being cancelled. I've raised this question to my hosting company, but all they told me was: "This is down to the way the software is configured on your server" This is currently a Magento 1.4.0.1 standard installation as far as payment gateways are concerned. What on earth could this statement mean? Is there some configuration that I need to do to make Magento listen to these requests and respond properly?

• Fiscal quarter vs calendar quarter

  - by Geotarget

  I'm building a Date/Time class with a "configurable quarter" system as follows. User specifies which month the quarter starts at (config) Set of functions to deal with quarters (next quarter, prev quarter, etc) All quarter functions respect the config Now this class is primarily to be used for fiscal quarter calculations. So assuming I have this class with a configurable "quarter" system, would I need another parallel set of functions for calendar quarters too? What are the applications for calendar quarters anyways? By calendar quarters I mean where Q1 is Jan-Mar, and Q4 is Oct-Dec. By fiscal quarters I mean whatever standard your Country uses (in India Q1 starts in April)

• Vocabulary: Should I call this apply or map?

  - by Carlos Vergara

  So, I'm tasked with organizing the code and building a library with all the common code among our products. One thing that seems to happen all the time and I wanted to abstract is posted below in pseudocode, and I don't know how to call it (different products have different domain specific implementations and names for it) list function idk_what_to_name_it ( list list_of_callbacks, value common_parameter ): list list_of_results = new list for_each(callback in list_of_callbacks) list_of_results.push(callback(common_parameter)) end for_each return list_of_results end function Would you call this specific construct a list ListOfCallbacks.Map( value value_to_map) method or would it better be value Value.apply(list list_of_callbacks) I'm really curious about this kind of thing. Is there a standard guide for this stuff?

• Get and install Nvidia GeForce 8400 GS driver
