• Attaining credit card data

  - by Adam

  I've read the many posts on this site that say we are not allowed to store cc numbers if we are not pci-compliant. But, I'm wondering if it is possible to send a CC number through a form to an email address? Would that be still infringing on the standards? The reason I ask is that a local business owner wants to retrieve a number through a form on his website, so he can manually enter the cc info on his end. I'm assuming the only way to properly get a credit card number is to setup a merchant account? What's the best way to get a cc number without calling the actual customer? I'm thinking email is a bad idea as well.

• How to handle estimates for programmers joining the team?

  - by Jordan

  Iteration has already started, new programmer joins the team, task X has already been estimated to be 30 hours by a different developer. What is the best practice in this situation? new developer runs with the given estimate (the idea being that any discrepancy will be corrected for when velocity is calculated?) new developer re-estimates task? (if so, what if it's significantly higher and no longer fits in the iteration?) throw our hands up and go back to waterfall? something else entirely?

• Time tracking and payment registration architecture

  - by egis

  ?itle might be a little bit incorrect. :) Anyway, I'm building a software where employees input time they worked per day (work hours) and employer "pays" for this time. "Payment" is done outside this system, so employer just "confirms" (checkbox or something like this) which work hours are paid. So the question is - what is the best way (both UI and data storage wise) to implement this? At the moment I have this idea: Employee selects week and manually (with some Javascript helpers, like "fill the same time for all days") inputs work hours in every day of the week. Employer confirms payment the same way employee inputs data (selects week, confirms each day). Data is saved in DB as unix timestamp (one day per table row). Problem is 14 inputs (7 days * ("hours from" + "hours to" input), yet this approach seems kinda easy to implement. Maybe I'm overlooking something and this can be done differently and better? Maybe someone has any example of already working software?

• How to use short breaks at work effectively for self-development?

  - by Alaudo

  At the moment my daily work as a developer requires me to have short 10-20 min breaks after every 2-3 hours. It would be nice if I could use those effectively to improve my expertise in programming or CS in general. I tried several things: Reading jokes online gets boring very soon. Trying to solve some (even the most simple) tasks from different code contests requires more time, as long as I have some idea of an algorithm the time is over. Reading a randomly picked Wikipedia-article about Computer Science: depending upon the article sometimes it requires more time and is not an easy reading for a break. So, I ended up reading StackOverflow questions and answers with most votes: that is entertaining and educative. Do you have any other suggestions?

• 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.

• I am not speaking at SQL Connections February 2011 meeting in Chicago suburbs

  - by Alexander Kuznetsov

  Usually it is an honor when we get to present to a user group, but not this time, so let me explain. I have no idea how my presentation got briefly mentioned in the invitation which went out today, without my consent. I have never asked or agreed to speak at SQL Connections February 2011 meeting in Chicago suburbs. Yet I apologize for any inconvenience it might have caused. I was going to speak at the meeting of December 2010, which was agreed by email with the person in charge. I had spent some...(read more)

• XNA Skinned Model - Keyframe.Bone out of range exception

  - by idlackage

  I'm getting an IndexOutOfRangeException on this line of AnimationPlayer.cs: boneTransforms[keyframe.Bone] = keyframe.Transform; I don't get what it's really referring to. The error happens when keyframe.Bone is 14, but I have no idea what that's supposed to mean. The 14th bone of my model? What would that even be? I read this thread, but nothing there seemed to work. I don't have many bones, stray edges/verts, unassigned verts, unparented/non-root bones, or bones with dots in the name. What else can I be missing? Thank you for any help!

• What are the downsides of leaving automation tags in production code?

  - by joshin4colours

  I've been setting up debug tags for automated testing of a GWT-based web application. This involves turning on custom debug id tags/attributes for elements in the source of the app. It's a non-trivial task, particularly for larger, more complex web applications. Recently there's been some discussion of whether enabling such debug ids is a good idea to do across the board. Currently the debug ids are only turned on in development and testing servers, not in production. There have been points raised that enabling debug ids does cause performance to take a hit, and that debug ids in production may lead to security issues. What are benefits of doing this? Are there any significant risks for turning on debug tags in production code?

• After executing a command in the terminal, I sometimes can't execute another

  - by jreed121

  First off sorry for the noob question, I'm sure it's been asked before but I have no idea how to phrase it eloquently... Sometimes when I open/run/execute (unsure of proper term) an application (?lol) from the terminal like geany ie: geany filename.php or maybe run a node.js script: node server.js The command will execute fine, but I'm then left without the ability to execute any other commands unless I open another terminal. my root@pcname:~$ is gone and when I try typing in something else and hitting Enter it just breaks to the next line. I've noticed that sometimes I can hit CTRL+D and it'll give me my prompt back (sorry is prompt even the right name for it?) So could someone please explain why this is happening and how I can get back to the prompt without opening another terminal. Thanks, and sorry again for my noobery.

• Trying to figure out SDL pixel manipulation?

  - by NoobScratcher

  Hello so I've found code that plots a pixel in an SDL Screen Surface : void putpixels(int x, int y, int color) { unsigned int *ptr = (unsigned int*)Screen->pixels; int lineoffset = y * (Screen->pitch / 4 ); ptr[lineoffset + x ] = color; } But I have no idea what its actually doing here this is my thoughts. You make an unsigned integer to hold the unsigned int version of pixels then you make another integer to hold the line offset and it equals to multiply by pitch which is then divided by 4 ... Now why am I dividing it by 4 and what is the pitch and why do I multiply it?? Why must I change the lineoffset and add it to the x value then equal it to colors? I'm soo confused.. ;/ I found this function here - http://sol.gfxile.net/gp/ch02.html

• Assign keys to commands in Terminal?

  - by NES

  Is there a solution to assign special key combinations to words in terminal use. For example the less command is very usefull and i use i a lot to pipe the output of another process through it. The idea would be to set up special key combinations that are only active in terminal use assigned to write different commands? So pressing CTRL + l in terminal window could write | less or CTRL + G could stand for | grep Note: i just mean adding the letters to commandline not execute the finally. A similar way what's tabcompletion but more specific.

• Love2D engine for Lua; What about 3D?

  - by shadowprotocol

  Lua has been really awesome to learn, it's so simple. I really enjoy scripting languages, and I had an equally enjoyable time learning Python. The Love engine, http://love2d.org/, is really awesome, but I'm looking for something that can handle 3D as well. Is there anything that accommodates 3D in Lua? I'm still intrigued by the particle system of LOVE anyway and may just turn my idea into a 2D project with Particle lighting :) EDIT: I removed comments about Python - I want this to be a Lua topic. Thanks

• When to decide to introduce interfaces (pure abstract base classes) in C++?

  - by Honza Brabec

  Assume that you are developing a functionality and are 90% sure that the implementation class will stay alone. If I was in this position in Java I would probably not use the interface right now to keep the things simple. In Java it is easy to refactor the code and extract the interface later. In C++ the refactoring is not always so easy. It may require replacing values with smart pointers (because of the introduction of polymorphism) and other non-trivial tasks. On the other hand I don't much like the idea of introducing virtual calls when I am 90% sure they won't be needed. After all speed is one of the reasons to prefer C++ over simpler languages.

• C# replacing out parameters with struct

  - by Jonathan

  I'm encountering a lot of methods in my project that have a bunch of out parameters embedded in them and its making it cumbersome to call the methods as I have to start declaring the variables before calling the methods. As such, I would like to refactor the code to return a struct instead and was wondering if this is a good idea. One of the examples from an interface: void CalculateFinancialReturnTotals(FinancialReturn fr, out decimal expenses, out decimal revenue, out decimal levyA, out decimal levyB, out decimal profit, out decimal turnover, out string message) and if I was to refactor that, i would be putting all the out parameters in the struct such that the method signature is much simpler as below. [structName] CalculateFinancialReturnTotals(FinancialReturn fr); Please advise.

• Design patterns for effects between actors and technology

  - by changelog

  I'm working on my first game, and taking the opportunity to brush up my C++ (I want to make as much of it as portable as I can.) Whilst working on the technology tree and how it affects actors (spaceships, planets, crew, buildings, etc) I can't find a pattern that decouples these entities enough to feel like a clean approach. Just as an idea, here's the type of effects these actors can have on one another (and techs too) An engineer inside a spaceship boosts its shield A hero in a spaceship in a fleet increases morale A technology improves spaceships' travel distance A building in a planet improves its production The best I can come up with is the Observer pattern, and basically manage it more or less manually (when a crew member enters a spaceship, fire the event; when a new building is built in a planet, fire the event, etc etc.) but it seems to be too tightly coupled to me. I would love to get some ideas about how to approach this better.

• Page not found in browsers

  - by Chetan

  I'm using ubuntu 12.04.1, last upgraded from 12.04 I'm using mts mblaze to access internet. Two days ago, I was using vpn on my system, suddenly cisco disconnected & my system hung while I was accessing my office system. I didnt' have any other idea, so I forcibly shut down the system. After that, connection is made, but firefox or chromium both don't find any page. I think there's some problem with the system package. Please let me know a good solution. Regards, Chetan

• Audio codec consuming high battery power

  - by Vamsi Emani

  My powertop reports this for the two audio codec components. 4.85 W 100.0% Device Audio codec hwC0D3: Intel 4.85 W 100.0% Device Audio codec hwC0D0: Realtek I think 10 W for audio is too high. Can somebody please suggest me a way to reduce the power consumption? It'd be nice if someone could educate me on this, I have an idea about codecs in general but I have no clue about their internals? Why is it that these two components keep running always even when I am not listening to audio?

• Software design methods for Java or any other programming language

  - by IkerB

  I'm junior programmer and I would like to know how professionals write their code or which steps they follow when they are creating new software. I mean, which steps they follow, which programming methodology, software architecture design application software, etc. I would like to find a tutorial where they explain from the beginning which steps I have to follow from The Idea I have in my mind to the final version of the application in any language. Or perhaps how is your programming steps or rules that you used to follow. Because everytime I want to create the an application I spend few time on the design and a lot of time coding (I know, that's not good).

• Any enlightenment for understanding Object Oriented Programming? [closed]

  - by ????

  I studied computer science near the end of 1980s, and wasn't taught OOP that formally. With Pascal or C, when I understand the top-down design of functions, and the idea of black box, then everything just seem to make sense, as if there is a "oh I get it!" -- some kind of totally getting it and enlightenment feeling. But with OOP, all I know was the mechanics: the class, instance, method, inheritance, polymorphism, encapsulation. It was like, I knew all the "this is how it is", but never had the feeling of "I totally get it", the enlightened feeling. Would somebody be able to describe it, or point to a chapter in some book or paper which talks about OOP so that the reader can feel: "I totally get it!" on OOP?

• /usr/share/apport/apport-gpu-error-intel.py Error

  - by gopherballs

  I was on Ubuntu 12.10 and ran the system updates and after the re-install, the system became unstable and kept prompting me with the message "System Issue" and this as the error per Ubuntu "/usr/share/apport/apport-gpu-error-intel.py". After I tried re-starting, the issue is still appearing and the system ultimately freezes (requiring a hard reset). I tried a clean install of 12.10 and the system works fine until the newest updates are applied...it then returns to the same messages. I then tried a clean install of 12.04 LTS and just like 12.10 it works until the latest updates are applied. On 12.04, I tried to use the previous kernel - going from 3.5.0-26 to 3.5.0-23 and the issue is still there. Currently, I'm sitting on 12.04 LTS clean install without doing the updates and the system is working. Does anyone have an idea how to fix this? Thanks.

• Several domains using 302 redirect to our domain

  - by Yamaha32088

  I am wondering what implications we can run into if one of our dealers is redirecting several of their domains using a 302 to our domain. The reason they are doing this is because they want to have time to build on their current sites but still want some content on the domains they own. Currently our domain is under a Manual Penalty for back links that we are working on removing. I do not like the idea of them linking back to our site but I need logical reasons other than "because I don't want you to".

• Ubuntu: how to change the right click "open with" application order?

  - by ramgorur

  I am using Ubuntu 10.10 Maverick, when I try to open a plain text file using a program x, I do right click to access the "open with" application list. Suppose my current "open with" list is like below -- application z application y application x But I want it to be like -- application x application y application z i.e. I want to change the order of the list. I know that I can fix a "default program" for a particular file, but that's not what I am looking for. My question is which file defines this "open with" preferences? and if there is any way to tweak it. Any idea?

• Visual Tree Enumeration

  - by codingbloke

  I feel compelled to post this blog because I find I’m repeatedly posting this same code in silverlight and windows-phone-7 answers in Stackoverflow. One common task that we feel we need to do is burrow into the visual tree in a Silverlight or Windows Phone 7 application (actually more recently I found myself doing this in WPF as well).  This allows access to details that aren’t exposed directly by some controls.  A good example of this sort of requirement is found in the “Restoring exact scroll position of a listbox in Windows Phone 7”  question on stackoverflow.  This required that the scroll position of the scroll viewer internal to a listbox be accessed. A caveat One caveat here is that we should seriously challenge the need for this burrowing since it may indicate that there is a design problem.  Burrowing into the visual tree or indeed burrowing out to containing ancestors could represent significant coupling between module boundaries and that generally isn’t a good idea. Why isn’t this idea just not cast aside as a no-no?  Well the whole concept of a “Templated Control”, which are in extensive use in these applications, opens the coupling between the content of the visual tree and the internal code of a control.   For example, I can completely change the appearance and positioning of elements that make up a ComboBox.  The ComboBox control relies on specific template parts having set names of a specified type being present in my template.  Rightly or wrongly this does kind of give license to writing code that has similar coupling. Hasn’t this been done already? Yes it has.  There are number of blogs already out there with similar solutions.  In fact if you are using Silverlight toolkit the VisualTreeExtensions class already provides this feature.  However I prefer my specific code because of the simplicity principle I hold to.  Only write the minimum code necessary to give all the features needed.  In this case I add just two extension methods Ancestors and Descendents, note I don’t bother with “Get” or “Visual” prefixes.  Also I haven’t added Parent or Children methods nor additional “AndSelf” methods because all but Children is achievable with the addition of some other Linq methods.  I decided to give Descendents an additional overload for depth hence a depth of 1 is equivalent to Children but this overload is a little more flexible than simply Children. So here is the code:- VisualTreeEnumeration public static class VisualTreeEnumeration {     public static IEnumerable<DependencyObject> Descendents(this DependencyObject root, int depth)     {         int count = VisualTreeHelper.GetChildrenCount(root);         for (int i = 0; i < count; i++)         {             var child = VisualTreeHelper.GetChild(root, i);             yield return child;             if (depth > 0)             {                 foreach (var descendent in Descendents(child, --depth))                     yield return descendent;             }         }     }     public static IEnumerable<DependencyObject> Descendents(this DependencyObject root)     {         return Descendents(root, Int32.MaxValue);     }     public static IEnumerable<DependencyObject> Ancestors(this DependencyObject root)     {         DependencyObject current = VisualTreeHelper.GetParent(root);         while (current != null)         {             yield return current;             current = VisualTreeHelper.GetParent(current);         }     } }   Usage examples The following are some examples of how to combine the above extension methods with Linq to generate the other axis scenarios that tree traversal code might require. Missing Axis Scenarios var parent = control.Ancestors().Take(1).FirstOrDefault(); var children = control.Descendents(1); var previousSiblings = control.Ancestors().Take(1)     .SelectMany(p => p.Descendents(1).TakeWhile(c => c != control)); var followingSiblings = control.Ancestors().Take(1)     .SelectMany(p => p.Descendents(1).SkipWhile(c => c != control).Skip(1)); var ancestorsAndSelf = Enumerable.Repeat((DependencyObject)control, 1)     .Concat(control.Ancestors()); var descendentsAndSelf = Enumerable.Repeat((DependencyObject)control, 1)     .Concat(control.Descendents()); You might ask why I don’t just include these in the VisualTreeEnumerator.  I don’t on the principle of only including code that is actually needed.  If you find that one or more of the above  is needed in your code then go ahead and create additional methods.  One of the downsides to Extension methods is that they can make finding the method you actually want in intellisense harder. Here are some real world usage scenarios for these methods:- Real World Scenarios //Gets the internal scrollviewer of a ListBox ScrollViewer sv = someListBox.Descendents().OfType<ScrollViewer>().FirstOrDefault(); // Get all text boxes in current UserControl:- var textBoxes = this.Descendents().OfType<TextBox>(); // All UIElement direct children of the layout root grid:- var topLevelElements = LayoutRoot.Descendents(0).OfType<UIElement>(); // Find the containing `ListBoxItem` for a UIElement:- var container = elem.Ancestors().OfType<ListBoxItem>().FirstOrDefault(); // Seek a button with the name "PinkElephants" even if outside of the current Namescope:- var pinkElephantsButton = this.Descendents()     .OfType<Button>()     .FirstOrDefault(b => b.Name == "PinkElephants"); //Clear all checkboxes with the name "Selector" in a Treeview foreach (CheckBox checkBox in elem.Descendents()     .OfType<CheckBox>().Where(c => c.Name == "Selector")) {     checkBox.IsChecked = false; }   The last couple of examples above demonstrate a common requirement of finding controls that have a specific name.  FindName will often not find these controls because they exist in a different namescope. Hope you find this useful, if not I’m just glad to be able to link to this blog in future stackoverflow answers.

• A Year of Tuesdays: T-SQL Tuesday Meta-Roundup

  - by Adam Machanic

  Just over a year ago I kicked off T-SQL Tuesday , "a recurring, revolving blog party." The idea was simple: Each month a blog will host the party, and about a week before the second Tuesday of the month a theme will be posted. Any blogger that wishes to participate is invited to write a post on the chosen topic. The event is called "T-SQL Tuesday", but any post that is related to both SQL Server and the theme is fair game . So feel free to post about SSIS, SSRS, Java integration, or whatever other...(read more)
