• 2010 SQLPeople Person of the Year

  - by andyleonard

  Introduction Back in 2010, I started recognizing the SQLPeople Person of the Year. It's been a tradition ever since. "But Andy, you're writing this in 2010." Yep. Good eye, Pep. The Award Goes To: Steve Jones ( Blog | @way0utwest ). I am not a DBA - I'm a database developer. I joke and say I look like the world's greatest DBA when there's no contention, the jobs are finishing successfully, queries return data quickly and accurately, and the backups succeed. But anyone looks like the world's greatest...(read more)

• How does one pluralize <see cref="Notation">'s?

  - by Jordan

  What is the most appropriate way of writing this comment: /// <summary> /// Order - Identifies the ordinal location of this category /// relative to other listed categories. /// </summary> if I'm wanting to wrap "category" in <see> tags? I've considered: /// <summary> /// Order - Identifies the ordinal location of this <see cref="Category"/> /// relative to other listed <see cref="Category"/>'s. /// </summary> Do you see my dilemma? Edit: I should add that I am using Visual Studio's XML Comments. So I am somewhat restricted as to the schema. I believe cref has to point to a valid type reference.

• Things to install on a new machine revisited

  as I prepare to get a new dev machine at work, I write the things I am going to install on it, before writing the first line of code on that machine: Control Freak Tools: Everything Search Engine a free and amazingly fast search engine for files all over your machine. (just file names, not inside files). This is so fast I use it almost as a replacement for my start menu, but its also great for finding those files that get hidden and tucked away in dark places on my system. Ever had a situation...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.

• How to have a maintainable and manageable Javascript code base

  - by dade

  I am starting a new job soon as a frontend developer. The App I would be working on is 100% Javascript on the client side. all the server returns is an index page that loads all the Javascript files needed by the app. Now here is the problem: The whole of the application is built around having functions wrapped to different namespaces. And from what I see, a simple function like rendering the HTML of a page can be accomplished by having a call to 2 or more functions across different namespace... My initial thought was "this does not feel like the perfect solution" and I can just envisage a lot of issues with maintaining the code and extending it down the line. Now I would soon start working on taking the project forward and would like to have suggestions on good case practices when it comes to writing and managing a relatively large amount of javascript code.

• Problems after installing Ubuntu 11.10

  - by Andrew Orr

  I'm having trouble with Ubuntu 11.10. It has to do with nomodeset. After I boot into Ubuntu, it goes to a purple screen for about 10 seconds and then goes blank. After that nothing happens. I've read other people's questions about this and I know it has to do with enabling nomodeset. This worked for me when I was using the LiveCD mode, but now Ubuntu is permanently installed as a dual-boot system. Going into recovery mode doesn't work, pressing "e" in the boot loader and writing nomodeset after quiet splash doesn't work either. Holding shift any time it's booting doesn't work. I don't know what to do anymore. I have an HP Pavilion dv6 laptop with an AMD A6-3400M CPU, and my GPU is an AMD Radeon HD 6520G. I've never worked with Linux before so taking me through this step-by-step would be great. Thanks!

• What is 'work' in the Pomodoro Technique?

  - by Sachin Kainth

  I have just started to use Pomodoro today and I am trying to work out what I should and should not do during my 25 minute work time. For my 25 minute work stint I started to write some code and realised that I had done something similar in a related project so I opened that solution to copy and paste that existing code. Question is, is this allowed? Also, if during my 25 minutes I realise that there is an important work-related email that I need to send can I do that or should that wait for the next 25 minutes or the break. I am writing this question during my, now extended, 5 minute break. Is this work or is it a break? I really would appreciate some guidance as I really want to use Pomodoro to focus better on my work. Another thing that happened to me was that a Adobe AIR update alert came up on my desktop during the 25 minutes. Should I ignore such things until the break? Sachin

• Jump-start Your Mind

  - by João Angelo

  I haven’t written in a while mostly because I’ve spent my time reading what others wrote and today I’m writing purely motivated by what I just finished reading. Mindfire: Big Ideas for Curious Mind by Scott Berkun was such a pleasure to read and ended up igniting parts of my mind which I have to admit were becoming a bit numb that I felt the urge to take some time to first say thank you to the author and then recommend it to all your curious minds out there. Now, go read it… it’s time well spent.

• Embed IF text parser in another game?

  - by DragonFax

  Are there any existing interactive fiction text parsing engines that I can embed in another game or application? I'm looking to use something as a library. I can pass it the available objects and verbs from my own side. It will parse the sentences from the user and give me back some sort of structure/AST describing what the user asked for. Then my own code can then act upon that request. I don't need something SIRI level. The simple sentences and actions that current IF games support is fine. But I'm not looking to write a whole text/sentence parser myself. This isn't an If game and I can't write it entirely in an interactive-fiction language like inform 7. Unfortunatly, I can't seem to find any examples of anyone using the text parsing capabilities of these engines without writing the entire game in that engine's language.

• Why are there two different kinds of linking, i.e. static and dynamic?

  - by davidk01

  I've been bitten for the n-th time now by a library mismatch between a build and deployment environment. The build environment had libruby.so.2.0 and the deployment environment had libruby.a. One ruby was built with RVM, the other was built with ruby-build. The reason I ran into a problem was because zookeeper was compiled in a build environment that had the shared library but the deployment environment only had the static library. In all the years I've been writing application code I have never once wished that the binaries I was using where linked against shared objects. What is the reason the dichotomy persists to this day on modern operating systems?

• template for terms of condition for social media based website?

  - by Rubytastic

  Im looking for a template for a terms of usage text based on social media websites. Im actually a coder and not into the legal blabla in general. Ofcourse you could spend a thousand or 2 on a lawyer but just a 3/4 paper text shoulder;t be to hard to compile yourself with some help. Im not sure if this is the right spot to ask this question but I love stack overflow and none of the sites in stack exchange I could find matched better then this one. My first idea lets look at some social media websites and grab some of there text, rewrite it for own specific usage Are there templates on writing such document Same goes with a privacy policy actually.

• Why get dedicated hosting? [closed]

  - by user176105

  Possible Duplicate: How to find web hosting that meets my requirements? I just finished writing a website and I'm about to publish it. I was looking at hosting options and I was about to get regular hosting from godaddy, which is about $6 a month with unlimited bandwidth, 150 gb of data, 500 emails and 25 mysql databases. The other option is dedicated servers, which range a lot in price, but are around $200 a month. Why would someone choose dedicated servers? Is it becuase they max the limits of regular hosting or is it because the ram/cpu is shared on regular hosting? If the latter, what will happen if a lot of users come to my site and max the ram/cpu?

• Is Java's ElementCollection Considered a Bad Practice?

  - by SoulBeaver

  From my understanding, an ElementCollection has no primary key, is embedded with the class, and cannot be queried. This sounds pretty hefty, but it allows me the comfort of writing an enum class which also helps with internationalization (using the enum key for lookup in my ResourceBundle). Example: We have a user on a media site and he can choose in which format he downloads the files @Entity @Table(name = "user") public class User { /* snip other fields */ @Enumerated @ElementCollection( targetClass = DownloadFilePreference.class, fetch = FetchType.EAGER ) @CollectionTable(name = "download_file_preference", joinColumns = @JoinColumn(name = "user_id") ) @Column(name = "name") private Set<DownloadFilePreference> downloadFilePreferences = new HashSet<>(); } public enum DownloadFilePreference { MP3, WAV, AIF, OGG; } This seems pretty great to me, and I suppose it comes down to "it depends on your use case", but I also know that I'm quite frankly only an initiate when it comes to Database design. Some best practices suggest to never have a class without a primary key- even in this case? It also doesn't seem very extensible- should I use this and gamble on the chance I will never need to query on the FilePreferences?

• Understanding the Java Ecosystem

  - by syrion

  I have traditionally had the "luxury" of being a one-man development team. I've used Python extensively, have a reasonable command of Perl, PHP, and JavaScript. My problem is Java. I can write Java code. I'm not great at it--unlike Python, I rarely make use of anything unique to Java when I'm writing it. Furthermore, my experience is mostly in simple GUI/console programming. Unfortunately, I'm currently pursuing an IT degree where Java is the lingua franca. My database class is requiring that our projects be written in Java using servlets, and I just can't wrap my head around the ecosystem. Is there a good online overview of or tutorial on how the Java web ecosystem works? I have Thinking in Java, but it's mostly just the language itself (which I understand well enough to get by). I have looked at the Sun servlet tutorial, but it seems outdated.

• What counts as reinventing the wheel?

  - by dsimcha

  Do the following scenarios count as "reinventing the wheel" in your book? A solution exists, but not in the language you want to use, and existing solutions can't be interfaced with the language you want to use in a clean, idiomatic way. In principle you could get an existing library to do what you wanted with heavy modification, but you think it would probably be easier to just start from scratch. What you're writing has the same one-line description as stuff that's already been done, but you're targeting a different niche. For example, maybe your problem has been solved a zillion times before, but in a way that's inefficient for large datasets and your code works well for large datasets.

• Mobile Web or Objective-C?

  Cameron Moll is worried about a future in which we’ll all write Objective-C for the iPhone OS instead of writing web standards for the mobile web.At one point in time, J2ME (now Java ME) and WAP were the starting points for a discussion on mobile strategy and the web. Then, for a brief period of time, you talked about HTML/CSS. Now, for a growing majority of mobile strategies that don’t require a global presence on widely varying devices, the discussion begins with iPhone.Emphasis mine.

• Is there a real difference between dynamic analysis and testing?

  - by user970696

  Often testing is regarded as a dynamic analysis of a software. Yet while writing my thesis, the reviewer noted to me that dynamic analysis is about analyzing the program behind the scenes - e.g. profiling and that it is not the same as testing because its "analysis" which looks inside and observes. I know that "static analysis" is not testing, should we then separate this "dynamic analysis" also from testing? Some books do refer to dynamic analysis in this sense. I would maybe say that testing is a one mean of dynamic analysis?

• 2D Platform Game Jumping

  - by Bradley Kreuger

  I'm currently writing a game in XNA for fun which uses C#. I have got my sprites loaded and when the character moves right he looks like he is running right and when he moves left he looks like he is running left. I been looking everywhere for a good coding example for how to create a jumping ability. I have read all the physics stuff that I can stand and it doesn't help when I can't figure out how to use say space bar to jump yet can't keep them from using space just jump again until they land.

• How to specify which keys CapsLock affects?

  - by Seattle Jörg

  Using Maverick, I am not able to get the CapsLock behaviour I want: I would like it to affect essentially the alphabetical, numerical, and punctuation keys, i.e. all the keys that print something (as opposed to, say, the error keys), but only them. To illuminate this with an example: when writing code that uses % as the symbol for a comment, I want to be able to position the cursor at the start of a range of lines I want to comment out, then hit CapsLock, then iteratively hit the 5 key (using QWERTZ, Shift+5 gives %) and the arrow down key, so that I can quickly place a % at the start of the lines. Ubuntu in default configuration takes CapsLock literally, so that it affects only alphabetic keys. Under Preferences/Keyboard/Layout/Options I can make it act as a pressed Shift, but then the action of the arrow keys is to select text. All the other options available are equivalent to one of these two in my case. Is it possible to somehow get this behaviour? This is standard in Windows.

• PowerShell programming conventions

  - by Tahir Hassan

  Do you follow any any conventions when programming in PowerShell? For example, in scripts which are to be maintained long-term do you: Use the real cmdlet name or alias? Specify the cmdlet parameter name in full or only partially (dir -Recurse versus dir -r) When specifying string arguments for cmdlets do you enclose them in quotes (New-Object 'System.Int32' versus New-Object System.Int32 When writing functions and filters do you specify the types of parameters? Do you write cmdlets in the (official) correct case? For keywords like BEGIN...PROCESS...END do you write them in uppercase only? Thanks for any replies.

• Write own messaging system vs. utilize existing ones

  - by A.Rashad

  We are trying to have our own startup, with a middleware application to glue small applications with enterprise legacy systems. for such middle-ware to function properly, we will need some sort of messaging system to make different components talk to each other in a reliable way. the alternatives are: use an existing messaging system, such as 0MQ, jBOSS, WebSphere MQ, etc. build our own messaging system the way we see the problem I am more biased towards the later option for the following reasons: to have more control over our final product to avoid any licensing problems later on to learn about messaging while writing the code to invent something new, that might cost us lots of $$$ if reused an existing system What would you do if in my shoes?

• What would you do if your client required you not to use object-oriented programming?

  - by gunbuster363

  Would you try to persuade your client that using object-oriented programming is much cleaner? Or would you try to follow what he required and give him crappy code? Now I am writing a program to simulate the activity of ants in a grid. The ant can move around, pick up things and drop things. The problem is while the action of the ants and the positions of each ant can be tracked by class attributes easily (and we can easily create many instances of such ants) my client said that since he has a background in functional programming he would like the simulation to be made using functional programming. What would you do?

• Predicate delegate in C#

  - by Jalpesh P. Vadgama

  I am writing few post on different type of delegates and and this post also will be part of it. In this post I am going to write about Predicate delegate which is available from C# 2.0. Following is list of post that I have written about delegates. Delegates in C#. Multicast delegates in C#. Func delegate in C#. Action delegate in C#. Predicate delegate in C#: As per MSDN predicate delegate is a pointer to a function that returns true or false and takes generics types as argument. It contains following signature. Predicate<T> – where T is any generic type and this delegate will always return Boolean value. The most common use of a predicate delegate is to searching items in array or list. So let’s take a simple example. Following is code for that. Read More
