• Most important research article for software development [closed]

  - by Fabian Fagerholm

  Researchers all over the world collectively publish thousands of articles on software development topics every year, hoping to benefit practical software development in the long run. (Of course, some of them only publish to increase their publication count, but hopefully most still aim to advance the field.) But what is really useful for practical software development? Of all the research articles you have read, what do you consider being the most important one for the software development field? What is it about that article that makes it stand out as especially important in your view? Note: I deliberately chose the term "software development", but you can freely interpret it as "programming" or "software engineering", or anything else that fits into the "software development" category.

• Windows 8/Surface Lunch Event Summary

  - by Tim Murphy

  Today was a big day for Microsoft with two separate launch event.  The first for Windows 8 and all of it’s hardware partners.  The second was specifically to introduce the Microsoft Windows 8 Surface tablet.  Below are some of the take-aways I got from the webcasts. Windows 8 Launch The three general area that Microsoft focused on were the release of the OS itself, the public unveiling of the Windows Store and the new devices available from its hardware partners. The release of the OS focused on the fact that it will be available at mid-night tonight for both new PCs and for upgrades.  I can’t say that this interested me that much since it was already known to most people.  I think what they did show well was how easy the OS really is to use. The Windows Store is also not a new feature to those of us who have been running the pre-release versions of Windows 8 or have owned Windows Phone 7 for the past 2 years.  What was interesting is that the Windows Store launches with more apps available than any other platforms store at their respective launch.  I think this says a lot about how Microsoft focuses on the ability of developers to create software and make it available.  The of course were sure to emphasize that the Windows Store has better monetary terms for developers than its competitors. The also showed off the fact that XBox Music streaming is available for to all Windows 8 user for free.  Couple this with the Bing suite of apps that give you news, weather, sports and finance right out of the box and I think most people will find the environment a joy to use. I think the hardware demo, while quick and furious, really show where Windows shine: CHOICE!  They made a statement that over 1000 devices have been certified for Windows 8.  They showed tablets, laptops, desktops, all-in-ones and convertibles.  Since these devices have industry standard connectors they give a much wider variety of accessories and devices that you can use with them. Steve Balmer then came on stage and tried to see how many times he could use the “magical”.  He focused on how the Windows 8 OS is designed to integrate with SkyDrive, Skype and Outlook.com.  He also enforced that they think Windows 8 is the best choice for the Enterprise when it comes to protecting data and integrating across devices including Windows Phone 8. With that we were left to wait for the second event of the day. Surface Launch The second event of the day started with kids with magnets.  Ok, they were adults, but who doesn’t like playing with magnets.  Steven Sinofsky detached and reattached the Surface keyboard repeatedly, clearly enjoying himself.  It turns out that there are 4 magnets in the cover, 2 for alignment and 2 as connectors. They then went to giving us the details on the display.  The 10.6” display is optically bonded to the case and is optimized to reduce glare.  I think this came through very well in the demonstrations. The properties of the case were also a great selling point.  The VaporMg allowed them to drop the device on stage, on purpose, and continue working.  Of course they had to bring out the skate boards made from Surface devices. “It just has to feel right” was the reason they gave for many of their design decisions from the weight and size of the device to the way the kickstand and camera work together.  While this gave you the feeling that the whole process was trial and error you could tell that a lot of science went into the specs.  This included making sure that the magnets were strong enough to hold the cover on and still have a 3 year old remove the cover without effort. I am glad that they also decided the a USB port would be part of the spec since it give so many options.  They made the point that this allows Surface to leverage over 420 million existing devices.  That works for me. The last feature that I really thought was important was the microSD port.  Begin stuck with the onboard memory has been an aggravation of mine with many of the devices in the market today. I think they did job of really getting the audience to understand why you want this platform and this particular device.  Using personal examples like creating a video of a birthday party and being in it or the fact that the device was being used to live blog the event and control the lights and presentation.  They showed very well that it was not only fun but very capable of getting real work done.  Handing out tablets to the crowd didn’t hurt either.  In the end I really wanted a Surface even though I really have no need for one on a daily basis.  Great job Microsoft! del.icio.us Tags: Windows 8,Win8,Windows 8 Luanch

• How To Start Programming

  - by nayef harb

  I have taken a programming course 2 years ago but I haven't worked in programming since then. I recently found a programmer job, but there is no programming team so for me to gain valuable experience from. I am Programming by myself and making changes on a program already made by my Ex-colleague. I need to know what should I do to be on the right track for becoming a professional programmer without a team to take experience from. What are the good practices to improve and what are the bad ones? I'm using VB.Net, ASP.Net and SQL.

• When dealing with a static game board, what are some methods to make it more interesting?

  - by Ólafur Waage

  Let's say you have a game board that you look at. It does not move but there is some action going on. For example Chess, Checkers, Solitaire. The game I'm working on is not one of these but it's a good reference. What are some methods you can apply to the game or the design that increases the appeal of the game to the user? Of course you can make it prettier but what are some other methods you can use? For example: Visual cues, game design changes, user interface arrangement, etc.

• Can manager classes be a sign of bad architecture?

  - by Paul

  Lately I've begun to think that having lots of manager classes in your design is a bad thing. The idea hasn't matured enough for me to make a compelling argument, but here's a few general points: I found it's a lot harder for me to understand systems that rely heavily on "managers". This is because, in addition to the actual program components, you also have to understand how and why the manager is used. Managers, a lot of the time, seem to be used to alleviate a problem with the design, like when the programmer couldn't find a way to make the program Just WorkTM and had to rely on manager classes to make everything operate correctly. Of course, mangers can be good. An obvious example is an EventManager, one of my all time favorite constructs. :P My point is that managers seem to be overused a lot of the time, and for no good reason other than mask a problem with the program architecture. Are manager classes really a sign of bad architecture?

• Agile Tools For Handling Multiple Projects

  - by f1dave

  Currently I'm leading our agile team in an iteration manager role as well as doing my regular dev work. One of the difficulties I'm facing as an IM is tracking burn-down/burn-up; not because I can't produce graphs, but because there's multiple projects that this team is working on at one time. At present I have an excel workbook with sheets that contain a whole bunch of graphs, both at an overall team and by-project level. It's clunky and I spend more time tweaking formulas and double checking calculations than I'd really like. As such, I'm interested to know if anyone has used a tool that can effectively produce these sorts of reports, burn-downs, and predictions across multiple projects. I've seen http://www.pivotaltracker.com/ do some nice things, and of course there's JIRA/Greenhopper, but I'm not aware of those being used to track the progress of multiple projects within one team. If anyone's got an idea of some tools, or has faced a similar problem before, I'd love to hear from you.

• After installing Windows XP I can't boot into Ubuntu 12.04 LTS

  - by Osama

  I know that this issue may have been happened to many people and answered many times. For some reason, I had to install Windows XP beside Ubuntu 12.04 LTS. Once I did that, I'm no longer able to log on to my Ubuntu. The booting list screen doesn't show up. I tried some ways to fix that, one was to try Boot Repair (of course after opening Ubuntu live from a USB), however, the program didn't open after the installation had finished !! So how can I fix that? I hope you guys stick a little with my problem until it is solved

• How can you learn to code faster? [closed]

  - by SDGator

  Possible Duplicate: How to Code Faster (Without Sacrificing Quality) I think I code pretty well. I'd say I'm in the top 20% of the folks doing what I do (ASIC verification using System Verilog). But, out of the folks that I admire and aspire to be like, the difference isn't so much quality of code, but the fact that they can pump out reams of good quality code very quickly. Of course, they've been at it far longer than I have. Is it possible to learn to code faster without compromising quality? Or is that something that only comes with time and experience?

• Can GJK be used with the same "direction finding method" every time?

  - by the_Seppi

  In my deliberations on GJK (after watching http://mollyrocket.com/849) I came up with the idea that it ins not neccessary to use different methods for getting the new direction in the doSimplex function. E.g. if the point A is closest to the origin, the video author uses the negative position vector AO as the direction in which the next point is searched. If an edge (with A as an endpoint) is closest, he creates a normal vector to this edge, lying in the plane the edge and AO form. If a face is the feature closest to the origin, he uses even another method (which I can't recite from memory right now) However, while thinking about the implementation of GJK in my current came, I noticed that the negative direction vector of the newest simplex point would always make a good direction vector. Of course, the next vertex found by the support function could form a simplex that less likely encases the origin, but I assume it would still work. Since I'm currently experiencing problems with my (yet unfinished) implementation, I wanted to ask whether this method of forming the direction vector is usable or not.

• Small Business Websites and the Internet High Street

  Most professionals, running their small businesses from high street premises, rightly expend huge amounts of time and effort on finding the right site to trade from; a wealth of consideration is given to every detail of the work place, from the colour of the carpets to the style of chair; professional designers are enlisted and marketing specialist consulted and a great deal of thought is given by all as to just how attractive the place will be to potential customers. With the beautiful new signs in place, all that's left to do is await passing trade, of course other marketing will be done and business also comes from word of mouth, but it is this visual presence on the high street that is all important to such firms.

• Organisation GitHub account. Secure to use for personal projects?

  - by Mackey18

  So a large client of mine gave me access to their Organisation GitHub account. With it came a login for myself (on github.companyname.com) and of course access to certain repos on their company account (by switching the user to the company via the button in the top left). Now I was wondering, since I can create private repos for myself, is it safe for me to use these for non-related projects or can the company administrators access my user's repos despite being private? My understanding of Github is limited as it is, so this extra layer of complexity from the organisation account isn't helping too much. Thanks,Mike

• Where is a good place to learn how to develop games?

  - by pringlesinn

  I'm brazilian and I want to learn how to develop a game in some college or something like that, but I don't know any place here to learn it. Here is not that good either to develop games, as we don't have many companies to do that. So, I was thinking about working in some place else, while I study it. What I really want to know is, a good place to learn, and a country that developers are well payed to be able to pay my course and still have money to do something else. I'm a Java programmer, still learning a lot, but I want to do it later. A few years from now.

• poor performance while exporting data to excel from DB2

  - by Naga

  I am facing a performance issue while exporting data from DB2 to Excel 2003. Well the very first reason is file is about 10+ MB where it goes outofMemory Exception. I am using XLSTransformer and HSSFWorkbook classes to transform my xls file. I also have joins in my query( optional). But user most likely is going to choose these options. When they do so, of course, the data becomes huge and take lot of time and some times goes outOfMemory too. So Please advice me on this.

• Is there any performance difference between Ubuntu Unity and Classic/Fallback?

  - by user48949

  is there any difference between using Ubuntu Unity and Ubunt Classic/Fallback? Just to be clear, I'm not talking about the Launcher or the Dash. Of course Ubuntu Classic/Fallback doesn't have the Launcher/Dash, but this is not the difference I'm talking about. I mean differences related to performance, features, functionalities, compatibilities, etc. These kinds of differences. I'm asking this because I've heard the Fallback Mode is kind of "incomplete" when it's compared to Gnome Shell or Ubuntu Unity, so I just wanted to know whether or not it's true, because if it's true, I don't think using Fallback Mode is worth it.

• How can I set up private, per-user sections on Joomla?

  - by Michael Paulukonis

  For this weekend's GiveCamp project, my team has been tasked with adding some functionality to an existing Joomla-powered website for a non-profit. A certain type of user will login, and have access to a personal area where they can upload files, check for messages, see tasks that have been assigned, etc. Each user would have their own area. They would not be creating pages, and their information would only be visible to themselves (or a site-administrator, of course. No sort of weird HIPAA privacy involved). None of us have worked with Joomla before, but we'd like to help this non-profit. We're not sure if we're searching using the wrong terms, or if we're just not finding it. Is such a solution possible in Joomla? And/or are we better off building some standalone solution that interfaces with the same mySQL database as Joomla?

• 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!

• I Can't update 12.04 to 12.10 ERROR:"gpg: WARNING: This key is not certified with a trusted signature!"

  I'm trying to update to 12.10 from a 12.04 machine. When I ran the code sudo do-release-upgrade -d in my terminal and verified my password it checked for a new upgrade. I was then returned with this: gpg: Good signature from "Ubuntu Archive Automatic Signing Key <[email protected]>" gpg: WARNING: This key is not certified with a trusted signature! gpg: There is no indication that the signature belongs to the owner.` There of course is more but it looks like it may or may not be showing private information with it. What's causing this and how do I fix this.

• SEO: Is promoting your backlinks a good strategy for improving search results for my site's name?

  - by user4394

  I run a website that's been around for about three years in the sports space. I am successfully ranking well for targeted keywords, but searching for the name of my site itself returns very poor results - it shows my site, its FB/Twitter, and then 15 pages of unrelated spam that happen to contain two words that, when combined, form my website's name. After that, my backlinks begin to show up spordically. As far as I can tell, I simply don't have enough backlinks and the backlinks I do have are ranked worse than the spam. (Site Explorer lists 200 external links to any page on our domain and 20 external links directly to the front page). To counter this, my strategy is to promote my backlinks so they get a better page rank than the spam. Does that make sense? Am I going in the right direction or should I just focus on getting more backlinks pointing directly to my site? Thanks in advance and I'd be happy to answer any questions I can (without giving away my site of course).
