  • When runs a product out of support?

    That is a question I get regularly from customers. Microsoft has a great site where you can find that information. Unfortunately this site is not easy to find, and a lot of people are not aware of this site. A good reason to promote it a little. So if you ever get a question on this topic, go to http://support.microsoft.com/lifecycle/search/Default.aspx. At that site, you can find also the details of the policy Microsoft Support Lifecycle Policy The Microsoft Support Lifecycle policy took effect in October 2002, and applies to most products currently available through retail purchase or volume licensing and most future release products. Through the policy, Microsoft will offer a minimum of: 10 years of support (5 years Mainstream Support and 5 years Extended Support) at the supported service pack level for Business and Developer products 5 years Mainstream Support at the supported service pack level for Consumer/Hardware/Multimedia products 3 years of Mainstream Support for products that are annually released (for example, Money, Encarta, Picture It!, and Streets & Trips) Phases of the Support Lifecycle Mainstream Support Mainstream Support is the first phase of the product support lifecycle. At the supported service pack level, Mainstream Support includes: Incident support (no-charge incident support, paid incident support, support charged on an hourly basis, support for warranty claims) Security update support The ability to request non-security hotfixes Please note: Enrollment in a maintenance program may be required to receive these benefits for certain products Extended Support The Extended Support phase follows Mainstream Support for Business and Developer products. At the supported service pack level, Extended Support includes: Paid support Security update support at no additional cost Non-security related hotfix support requires a separate Extended Hotfix Support Agreement to be purchased (per-fix fees also apply) Please note: Microsoft will not accept requests for warranty support, design changes, or new features during the Extended Support phase Extended Support is not available for Consumer, Hardware, or Multimedia products Enrollment in a maintenance program may be required to receive these benefits for certain products Self-Help Online Support Self-Help Online Support is available throughout a product's lifecycle and for a minimum of 12 months after the product reaches the end of its support. Microsoft online Knowledge Base articles, FAQs, troubleshooting tools, and other resources, are provided to help customers resolve common issues.

  • Part 2: Career development as a Software Developer without becoming a manager.

    - by albertpascual
    Seems like my previous post inspired by the work of Michael “Doc” Norton was a great success for the amount of emails I have received. Yet amazed how many people didn’t want to discuss their questions in the comments  sections. I would encourage people to be more public, still I would like to reply to all of you on this public media. I still welcome those emails. What I found out is that many people feels like me, they want to be developers and still be compensated for their experience without wanting to take a job as a manager. Their perfect day is a full day of coding and learning. Many believe their companies will never pay a manager’s salary to a developer no matter what. Most of you ask how to get the ball rolling. And is the later that I’m addressing here, the previous group, will never try. What companies understand developers value and where can I find them? This is a very difficult question to ask, I don’t have a list of those companies or departments, I have seen in my past signs in companies bending backwards to compensate, in more ways the monetary, a developer that is a good resource to them. Allowing the person to move out of the state and still let them work for the company from home is a sign that company goes by individual cases. Allowing them to go to conference that will not benefit the company is another big sign. Simple signs like flexible hours and letting some people work from home. To see those signs you need to be working in that company for awhile and look at the departments where the manager is taking care of their employees in individual cases. Look for the department where people get quiet extra perks, where some people in the department work from home or remotely. In my experience, but not always true, medium to big companies, are prompt to recognize good developers. Then again, some companies just don’t get it and is when you see many technical people managing developers. For all the people that email me stating that developers can also be very good managers, I do not disagree, I just think that a good developers loves writing code, when you remove that part the better salary isn’t enough to keep a developer happy. Burned out developers appreciate being promoted to managers. How do I know I work in a bad company? In my experience I have been a consultant and seen many companies, a few signs I have learned about companies that will not recognize good developers are: When the turn over is pretty high, when developers are moving out in a big rate, no rocket scientist needs to tap you in the shoulder. When the company is looking always to outsource their development resources. The product is not that interesting nor the company cares too much for their final result and support. Code sweat shops. You’ll know when you start working in one of those. Run for the hills! Where do I start? Disclaimer: I have only based this post on Michael “Doc” Norton, this is just my interpretation and ideas. First thing is to look at Michael “Doc” Norton presentation Take Control of Your Development Career http://docondev.blogspot.com/ That should be the first thing any developer should look and follow like it was a pattern. I would personally recommend to find some language or pattern you are interested with and learn it, learn something that will make you happy. Second, join a User Group and get involve in the community. There are hundreds of user groups, and I’m sure you’ll find one in your city or near you town. Code Camps are Developers Meet Ups are also good resources. Third, I would join a open source project you are interested or better yet, create a new open source project with the new technology that you have learn and get coding. Fourth, create a Twitter account and follow the people that talks about the technology you are interested on. If you follow this 4 steps above I think you’ll be on your way, after they are complete, when you release your Open Source project you can say that you accomplished the first steps. Now, do not expect anything to change in your career life, you are changing and should not expect anything in return, besides borrowing some time from sleeping and your family. Creating a good schedule may help you, I find wasted time in many places that I use. Flying for work is actually one of those that allows me to do my best work on a airplane, don’t need to borrow time from anywhere else. Making sure you always have a light, charged laptop is so important. Next steps following the Michael “Doc” Norton Pattern or my interpretation of. First, help run a user group or better yet, start a new user group. I’ll add, as well, go to one conference a year and free development events around your city; Code Camps, Geek Dinners, etc. There are many free events sponsored by different companies for developers to get to know their products, I highly recommend those as the way to get connected. Second, chose a mentor, this is a very hard thing to do I experienced, find an expert in the technology you are learning that has the time for you, it is difficult, I wish you best of luck. Third, learn another technology or pattern, open your horizons a little bit more. Why not, if you had fun previously, keep doing it. Fourth, get involved in forums to answer and ask questions, getting notice in public forums is rewarding for your ego after such a long journey. Final steps following the Michael “Doc” Norton Pattern Teach what you know, become humble on your knowledge, find as many opportunities to teach and to get involved with the community, bring all that to your day job. Mr. Norton talks about getting naked, expose yourself to others in your knowledge and what you do not know. You are never too important for small opportunities, yet don’t  be afraid to take anything big and learn from the experience. Anytime you have the opportunity to talk to somebody that has reach the point the community knows his or her name, means that you should learn from it. Take opportunities that won’t make you money, yet will make you happy. Sometimes you need to spend money and time. Register talks in Code Camps and Dev Meet Ups, those are free, also go to Conference, Development Summits and Geek Diners for example. One day, people will pay you to attend. When will all these pay off? I don’t know. I’m still in the path, there are a few things that during your journey you may get little acknowledgements that you are in the correct path. In my case I think those are the little signs that tells you about your journey. I got awarded the Microsoft Most Valuable Professional for ASP.NET in 2007, 2008, 2009 and 2010. I got selected to speak at the DevConnections in Las Vegas in 2010 and Orlando 2011. I do believe that I do have a long way to go, yet what I do makes me happy and I hope I can keep doing for years to come. Every year I can see an improvement on my code, and more frameworks and languages are under my belt, I learn to embrace them all as well as in my daily job, I have been able to work in a few projects beyond my department. I’m a learner and believer of the Michael “Doc” Norton pattern. Looking forward to learn more about it to be able to apply it better. In my short journey I now see my mistakes, I did a few things right, I have been listening the intelligent people and not being afraid to move along the technology changes. In my professional life, I have tried to avoid being placed in only one technology and product. I have always share my code and never confused anybody that wanted to take over any of my projects, I didn’t think anything I created as my own nor care too much when politics didn’t see my vision. I stayed flexible, ready and visible, yet humble. I keep my head just below the clouds, and avoided managers meetings. I credit my manager for my success, and I faulted publicly only myself for the failures. Hope this helps. Cheers, Al Follow me in Twitter  Read my previous post tweetmeme_url = 'http://weblogs.asp.net/albertpascual/archive/2010/12/09/part-2-career-development-as-a-software-developer-without-becoming-a-manager.aspx'; tweetmeme_source = 'alpascual';

  • Google Webmasters Tools strange 404 errors referred from same site

    - by Out of Control
    Starting about a month ago, I noticed a sudden increase in 404 errors in Webmasters Tools for one of my sites (over 1400 errors so far). All the errors are being referred from my own site to non existent pages. The 404 error URLs are all of the same format: URL: http://www.helloneighbour.com/save/1347208508000 The number on the end appears to be a timestamp followed by 3 zeros. The referring page, in this case is : Linked from http://www.helloneighbour.com/save/cmw-insurance-insurance-burnaby When I look at the source code of that page, or I use Webmaster tools to view the page as Google sees it, I can't find any link that comes close to what is above. I built the site, and I can't find any place that might be causing these false links either. The server logs (access and error) don't show Google or anyone else trying to access these links. I've marked all these pages as fixed, and waited a couple of weeks, only to find the errors come back again over the last few days. I'm wondering if anyone else has seen anything strange like this, or if someone might have a way for me to debug, replicate this error myself.

  • SQL SERVER – Installing Data Quality Services (DQS) on SQL Server 2012

    - by pinaldave
    Data Quality Services is very interesting enhancements in SQL Server 2012. My friend and SQL Server Expert Govind Kanshi have written an excellent article on this subject earlier on his blog. Yesterday I stumbled upon his blog one more time and decided to experiment myself with DQS. I have basic understanding of DQS and MDS so I knew I need to start with DQS Client. However, when I tried to find DQS Client I was not able to find it under SQL Server 2012 installation. I quickly realized that I needed to separately install the DQS client. You will find the DQS installer under SQL Server 2012 >> Data Quality Services directory. The pre-requisite of DQS is Master Data Services (MDS) and IIS. If you have not installed IIS, you can follow the simple steps and install IIS in your machine. Once the pre-requisites are installed, click on MDS installer once again and it will install DQS just fine. Be patient with the installer as it can take a bit longer time if your machine is low on configurations. Once the installation is over you will be able to expand SQL Server 2012 >> Data Quality Services directory and you will notice that it will have a new item called Data Quality Client.  Click on it and it will open the client. Well, in future blog post we will go over more details about DQS and detailed practical examples.

  • SQL SERVER – Capturing Wait Types and Wait Stats Information at Interval – Wait Type – Day 5 of 28

    - by pinaldave
    Earlier, I have tried to cover some important points about wait stats in detail. Here are some points that we had covered earlier. DMV related to wait stats reset when we reset SQL Server services DMV related to wait stats reset when we manually reset the wait types However, at times, there is a need of making this data persistent so that we can take a look at them later on. Sometimes, performance tuning experts do some modifications to the server and try to measure the wait stats at that point of time and after some duration. I use the following method to measure the wait stats over the time. -- Create Table CREATE TABLE [MyWaitStatTable]( [wait_type] [nvarchar](60) NOT NULL, [waiting_tasks_count] [bigint] NOT NULL, [wait_time_ms] [bigint] NOT NULL, [max_wait_time_ms] [bigint] NOT NULL, [signal_wait_time_ms] [bigint] NOT NULL, [CurrentDateTime] DATETIME NOT NULL, [Flag] INT ) GO -- Populate Table at Time 1 INSERT INTO MyWaitStatTable ([wait_type],[waiting_tasks_count],[wait_time_ms],[max_wait_time_ms],[signal_wait_time_ms], [CurrentDateTime],[Flag]) SELECT [wait_type],[waiting_tasks_count],[wait_time_ms],[max_wait_time_ms],[signal_wait_time_ms], GETDATE(), 1 FROM sys.dm_os_wait_stats GO ----- Desired Delay (for one hour) WAITFOR DELAY '01:00:00' -- Populate Table at Time 2 INSERT INTO MyWaitStatTable ([wait_type],[waiting_tasks_count],[wait_time_ms],[max_wait_time_ms],[signal_wait_time_ms], [CurrentDateTime],[Flag]) SELECT [wait_type],[waiting_tasks_count],[wait_time_ms],[max_wait_time_ms],[signal_wait_time_ms], GETDATE(), 2 FROM sys.dm_os_wait_stats GO -- Check the difference between Time 1 and Time 2 SELECT T1.wait_type, T1.wait_time_ms Original_WaitTime, T2.wait_time_ms LaterWaitTime, (T2.wait_time_ms - T1.wait_time_ms) DiffenceWaitTime FROM MyWaitStatTable T1 INNER JOIN MyWaitStatTable T2 ON T1.wait_type = T2.wait_type WHERE T2.wait_time_ms > T1.wait_time_ms AND T1.Flag = 1 AND T2.Flag = 2 ORDER BY DiffenceWaitTime DESC GO -- Clean up DROP TABLE MyWaitStatTable GO If you notice the script, I have used an additional column called flag. I use it to find out when I have captured the wait stats and then use it in my SELECT query to SELECT wait stats related to that time group. Many times, I select more than 5 or 6 different set of wait stats and I find this method very convenient to find the difference between wait stats. In a future blog post, we will talk about specific wait stats. Read all the post in the Wait Types and Queue series.

  • Better Embedded 2013

    - by Valter Minute
    Originally posted on: http://geekswithblogs.net/WindowsEmbeddedCookbook/archive/2013/07/30/better-embedded-2013.aspx On July 8th and 9th I had a chance to attend and speak at the Better Embedded 2013 conference in Florence. Visiting Florence is always a pleasure, but having a chance to attend to such an interesting conference and to meet Marco Dal Pino, Paolo Patierno, Mirco Vanini and many other embedded developers made those two days an experience to be remembered. I did two sessions, one on Windows Embedded Standard and “PCs” usage in the embedded world and another one on Android for Embedded devices, you can find the slides on the better embedded website: www.betterembedded.it. You can also find slides for many other interesting session, ranging from the .NET microframework to Linux Embedded, from QT Quick to software licenses. Packing many different resources about embedded systems in a conference was not easy but the result is a very nice mix of contents ranging from firmware development to cloud-based systems. This is a great way to have an overview of what’s new or interesting in embedded systems and to get great ideas about how to build your new device. Don’t forget to follow @Better_Embedded on twitter to not miss next year conference! Thanks to the better embedded team for having allowed me to use some of the official pictures in this blog post. You can find a good selection of those pictures (just to experience the atmosphere of the conference) on its Facebook page: http://dvlr.it/DHDB

  • Depth interpolation for z-buffer, with scanline

    - by Twodordan
    I have to write my own software 3d rasterizer, and so far I am able to project my 3d model made of triangles into 2d space: I rotate, translate and project my points to get a 2d space representation of each triangle. Then, I take the 3 triangle points and I implement the scanline algorithm (using linear interpolation) to find all points[x][y] along the edges(left and right) of the triangles, so that I can scan the triangle horizontally, row by row, and fill it with pixels. This works. Except I have to also implement z-buffering. This means that knowing the rotated&translated z coordinates of the 3 vertices of the triangle, I must interpolate the z coordinate for all other points I find with my scanline algorithm. The concept seems clear enough, I first find Za and Zb with these calculations: var Z_Slope = (bottom_point_z - top_point_z) / (bottom_point_y - top_point_y); var Za = top_point_z + ((current_point_y - top_point_y) * Z_Slope); Then for each Zp I do the same interpolation horizontally: var Z_Slope = (right_z - left_z) / (right_x - left_x); var Zp = left_z + ((current_point_x - left_x) * Z_Slope); And of course I add to the zBuffer, if current z is closer to the viewer than the previous value at that index. (my coordinate system is x: left - right; y: top - bottom; z: your face - computer screen;) The problem is, it goes haywire. The project is here and if you select the "Z-Buffered" radio button, you'll see the results... (note that the rest of the options before "Z-Buffered" use the Painter's algorithm to correctly order the triangles. I also use the painter's algorithm -only- to draw the wireframe in "Z-Buffered" mode for debugging purposes) PS: I've read here that you must turn the z's into their reciprocals (meaning z = 1/z) before you interpolate. I tried that, and it appears that there's no change. What am I missing? (could anyone clarify, precisely where you must turn z into 1/z and where to turn it back?)

  • SQL SERVER – Weekly Series – Memory Lane – #038

    - by Pinal Dave
    Here is the list of selected articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2007 CASE Statement in ORDER BY Clause – ORDER BY using Variable This article is as per request from the Application Development Team Leader of my company. His team encountered code where the application was preparing string for ORDER BY clause of the SELECT statement. Application was passing this string as variable to Stored Procedure (SP) and SP was using EXEC to execute the SQL string. This is not good for performance as Stored Procedure has to recompile every time due to EXEC. sp_executesql can do the same task but still not the best performance. SSMS – View/Send Query Results to Text/Grid/Files Results to Text – CTRL + T Results to Grid – CTRL + D Results to File – CTRL + SHIFT + F 2008 Introduction to SPARSE Columns Part 2 I wrote about Introduction to SPARSE Columns Part 1. Let us understand the concept of the SPARSE column in more detail. I suggest you read the first part before continuing reading this article. All SPARSE columns are stored as one XML column in the database. Let us see some of the advantage and disadvantage of SPARSE column. Deferred Name Resolution How come when table name is incorrect SP can be created successfully but when an incorrect column is used SP cannot be created? 2009 Backup Timeline and Understanding of Database Restore Process in Full Recovery Model In general, databases backup in full recovery mode is taken in three different kinds of database files. Full Database Backup Differential Database Backup Log Backup Restore Sequence and Understanding NORECOVERY and RECOVERY While doing RESTORE Operation if you restoring database files, always use NORECOVER option as that will keep the database in a state where more backup file are restored. This will also keep database offline also to prevent any changes, which can create itegrity issues. Once all backup file is restored run RESTORE command with a RECOVERY option to get database online and operational. Four Different Ways to Find Recovery Model for Database Perhaps, the best thing about technical domain is that most of the things can be executed in more than one ways. It is always useful to know about the various methods of performing a single task. Two Methods to Retrieve List of Primary Keys and Foreign Keys of Database When Information Schema is used, we will not be able to discern between primary key and foreign key; we will have both the keys together. In the case of sys schema, we can query the data in our preferred way and can join this table to another table, which can retrieve additional data from the same. Get Last Running Query Based on SPID PID is returns sessions ID of the current user process. The acronym SPID comes from the name of its earlier version, Server Process ID. 2010 SELECT * FROM dual – Dual Equivalent Dual is a table that is created by Oracle together with data dictionary. It consists of exactly one column named “dummy”, and one record. The value of that record is X. You can check the content of the DUAL table using the following syntax. SELECT * FROM dual Identifying Statistics Used by Query Someone asked this question in my training class of query optimization and performance tuning.  “Can I know which statistics were used by my query?” 2011 SQL SERVER – Interview Questions and Answers – Frequently Asked Questions – Day 14 of 31 What are the basic functions for master, msdb, model, tempdb and resource databases?

Find Column Used in Stored Procedure – Search Stored Procedure for Column Name Very interesting conversation about how to find column used in a stored procedure. There are two different characters in the story and both are having a conversation about how to find column in the stored procedure. Here are two part story Part 1 | Part 2 SQL SERVER – 2012 Functions – FORMAT() and CONCAT() – An Interesting Usage Generate Script for Schema and Data – SQL in Sixty Seconds #021 – Video In simple words, in many cases the database move from one place to another place. It is not always possible to back up and restore databases. There are possibilities when only part of the database (with schema and data) has to be moved. In this video we learn that we can easily generate script for schema for data and move from one server to another one. INFORMATION_SCHEMA.COLUMNS and Value Character Maximum Length -1 I often see the value -1 in the CHARACTER_MAXIMUM_LENGTH column of INFORMATION_SCHEMA.COLUMNS table. I understand that the length of any column can be between 0 to large number but I do not get it when I see value in negative (i.e. -1). Any insight on this subject?

  • Line Numbering in Notepad-Week 41

    - by OWScott
    You can find this week’s video here. Notepad is so simple, yet so useful. Yet, at times the "Go To" appears to break and doesn't work as expected. This week's video is short and sweet. Learn about line numbering in notepad. One of my all-time favorite applications is notepad. You may think I’m joking, but I’ve grown quite fond of notepad over the years. Like a faithful friend, always there for you when you need it. Whether it’s an old computer or new, it opens instantly. I can’t remember notepad ever crashing. Wish I could say that for most other applications. This week’s lesson is a quick one, but if you’ve ever run into issues with line numbering in notepad, I hope you find it useful. I remember the first time the “Go To” feature didn’t work in notepad for me. It took me a while to figure it out so I hope to save you the grief that I went through. Watch this week’s video for a couple quick tips on the tried and true notepad. This is now week 41 of a 52 week series for the web pro.

  • Xamarin Designer for Android Article

    - by Wallym
    The latest version of Mono for Android includes a long-awaited design surface. Learn how it works.It's interesting to look at the needs of various segments of developers. When I first start looking at an environment, the first thing I need to understand is the UI. I'm not magically born with some knowledge about the environment and don't learn well by just reading, so I need some help in getting started. I found this was true when I started Windows based development in the early 1990s, Dynamic Web in the late 1990s, ASP.NET in 2000, Silverlight/WPF, iPhone and Android. I find that getting up to speed with a UI is the single biggest deterrent for someone learning a platform. I find that as a beginner I need the features provided by a design surface. It's only as I grow and become comfortable with a platform that I find that building a UI by hand is more productive. Even as I get more advanced, I still can learn from a designer, so it has value as I grow into a platform.I hope that this article helps you as you dive into Android Development.

  • Third-party open-source projects in .NET and Ruby and NIH syndrome

    - by Anton Gogolev
    The title might seem to be inflammatory, but it's here to catch your eye after all. I'm a professional .NET developer, but I try to follow other platforms as well. With Ruby being all hyped up (mostly due to Rails, I guess) I cannot help but compare the situation in open-source projects in Ruby and .NET. What I personally find interesting is that .NET developers are for the most part severely suffering from the NIH syndrome and are very hesitant to use someone else's code in pretty much any shape or form. Comparing it with Ruby, I see a striking difference. Folks out there have gems literally for every little piece of functionality imaginable. New projects are popping out left and right and generally are heartily welcomed. On the .NET side we have CodePlex which I personally find to be a place where abandoned projects grow old and eventually get abandoned. Now, there certainly are several well-known and maintained projects, but the number of those pales in comparison with that of Ruby. Granted, NIH on the .NET devs part comes mostly from the fact that there are very few quality .NET projects out there, let alone projects that solve their specific needs, but even if there is such a project, it's often frowned upon and is reinvented in-house. So my question is multi-fold: Do you find my observations anywhere near being correct? If so, what are your thoughts on quality and quantitiy of OSS projects in .NET? Again, if you do agree with my thoughts on "NIH in .NET", what do you think is causing it? And finally, is it Ruby's feature set & community standpoint (dynamic language, strong focus on testing) that allows for such easy integration of third-party code?

  • MySQL Enterprise Monitor 2.3.12 Is Now Available!

  • Extreme Optimization – Curves (Function Mapping) Part 1

    - by JoshReuben
    Overview ·        a curve is a functional map relationship between two factors (i.e. a function - However, the word function is a reserved word). ·        You can use the EO API to create common types of functions, find zeroes and calculate derivatives - currently supports constants, lines, quadratic curves, polynomials and Chebyshev approximations. ·        A function basis is a set of functions that can be combined to form a particular class of functions.   The Curve class ·        the abstract base class from which all other curve classes are derived – it provides the following methods: ·        ValueAt(Double) - evaluates the curve at a specific point. ·        SlopeAt(Double) - evaluates the derivative ·        Integral(Double, Double) - evaluates the definite integral over a specified interval. ·        TangentAt(Double) - returns a Line curve that is the tangent to the curve at a specific point. ·        FindRoots() - attempts to find all the roots or zeroes of the curve. ·        A particular type of curve is defined by a Parameters property, of type ParameterCollection   The GeneralCurve class ·        defines a curve whose value and, optionally, derivative and integrals, are calculated using arbitrary methods. A general curve has no parameters. ·        Constructor params:  RealFunction delegates – 1 for the function, and optionally another 2 for the derivative and integral ·        If no derivative  or integral function is supplied, they are calculated via the NumericalDifferentiation  and AdaptiveIntegrator classes in the Extreme.Mathematics.Calculus namespace. // the function is 1/(1+x^2) private double f(double x) {     return 1 / (1 + x*x); }   // Its derivative is -2x/(1+x^2)^2 private double df(double x) {     double y = 1 + x*x;     return -2*x* / (y*y); }   // The integral of f is Arctan(x), which is available from the Math class. var c1 = new GeneralCurve (new RealFunction(f), new RealFunction(df), new RealFunction(System.Math.Atan)); // Find the tangent to this curve at x=1 (the Line class is derived from Curve) Line l1 = c1.TangentAt(1);

  • How to deal with OpenGL and Fullscreen on OS X

    - by Armin Ronacher
    I do most of my development on OS X and for my current game project this is my target environment. However when I play games I play on Windows. As a windows gamer I am used to Alt+Tab switching from within the game to the last application that was open. On OS X I currently can't find either a game that supports that nor can I find a way to make it possible. My current project is based on SDL 1.3 and I can see that cmd+tab is a sequence that is sent directly to my application and not intercepted by the operating system. Now my first attempt was to hide the rendering window on cmd+tab which certainly works, but has the disadvantage that a hidden OpenGL window in SDL cannot be restored when the user tabs back to the application. First of all, there is no event fired for that or I can't find it, secondly the core problem is that when that application window is hidden, my game is still the active application, just that the window disappeared. That is incredible annoying. Any ideas how to approximate the windows / linux behavior for alt+tab?

  • 2D Side Scrolling game and "walk over ground" collision detection

    - by Fire-Dragon-DoL
    The question is not hard, I'm writing a game engine for 2D side scrolling games, however I'm thinking to my 2D side scrolling game and I always come up with the problem of "how should I do collision with the ground". I think I couldn't handle the collision with ground (ground for me is "where the player walk", so something heavily used) in a per-pixel way, and I can't even do it with simple shape comparison (because the ground can be tilted), so what's the correct way? I'know what tiles are and i've read about it, but how much should be big each tile to not appear like a stairs?Are there any other approach? I watched this game and is very nice how he walks on ground: http://www.youtube.com/watch?v=DmSAQwbbig8&feature=player_embedded If there are "platforms" in mid air, how should I handle them?I can walk over them but I can't pass "inside". Imagine a platform in mid air, it allows you to walk over it but limit you because you can't jump in the area she fits Sorry for my english, it's not my native language and this topic has a lot of keywords I don't know so I have to use workarounds Thanks for any answer Additional informations and suggestions: I'm doing a game course in this period and I asked them how to do this, they suggested me this approach (a QuadTree): -All map is divided into "big nodes" -Each bigger node has sub nodes, to find where the player is -You can find player's node with a ray on player position -When you find the node where the player is, you can do collision check through all pixels (which can be 100-200px nothing more) Here is an example, however i didn't show very well the bigger nodes because i'm not very good with photoshop :P How is this approach?

    Have you ever been browsing through photos or videos on your PC, and noticed that the thumbnails weren’t showing up properly? Sometimes they get corrupted, and you can quickly rebuild them to fix the problem. Just for some background, let’s walk through what we’re talking about. Normally, when you’re browsing around your files, you’ll see thumbnails for pictures and videos that you are viewing. These thumbnails are all generated, and stored in a cache to make browsing files faster. But sometimes… the cache gets corrupted, and we need to rebuild them. Here’s an example of what happens when it goes out of whack… Rebuilding the Windows 7 Thumbnail Cache All you have to do is open up Disk Cleanup through the start menu search box (just type in disk cleanup to find it) Just make sure that Thumbnails is checked, and then click OK to run through the cleaning process.

  • Blogging After The Blog Boom

    - by Tim Murphy
    I have been blogging on Geeks With Blogs since 2005 and on other blogging sites before that.  In this age of Twitter, Facebook and G+ it feels like we are in the post-blog age and yet here I continue.  There are several reasons for this.  The first is that I still find it to be the best place for self publishing long form thought that won’t fit well on Twitter or Facebook.  Google+ allows for this type of content, but it suffers from the same scroll factor as the other social media platforms.  If you aren’t looking at the right moment you miss it.  On a blog I can put complete thoughts with examples and people can find what they want via key words or search engine. The second reason I blog is to have a place for me to put information I want to be able to reference back to later.  Although I use OneNote which is now accessible everywhere the blog gives me somewhere to refer co-workers and clients when I have solutions for problems I have previously solved. I know that other people use their blog as a resume builder, but that hasn’t been one of my primary concerns.  Don’t get me wrong.  Opportunities do come up because you put out well thought out, topical material.  That just isn’t one of my top motivators. I don’t always find the time to blog or even have anything to say lately, but I will continue to produce content for myself and others to learn from and hopefully enjoy. del.icio.us Tags: Blogging,Social Media

  • Change Password vs. Reset Password-Week 42

    - by OWScott
    You can find this week’s video here. The differences between change password and reset password are not well known. This week's video walks through the differences and shows them in action. Tune in to find out more about password management. It wasn’t until fairly recently that I realized that there is a difference between a change password and a reset password. One is safe, while the other not so much. I remember when Windows Server 2003 was first released and resetting a user’s password had a distinct warning about irreversible loss of information. I wondered why it wasn’t mentioned in previous operating systems, but I also wondered if it was true since I never personally noticed any impact. It wasn’t until about a year ago when I really dug in to understand this topic better. This week’s lesson covers the differences between a change password and a reset password. In this video we also take a look at it in action so that we have a solid understanding of the topic, and briefly discuss how it works for programming APIs too. This is now week 42 of a 52 week series for the web pro. You can view past and future weeks here: http://dotnetslackers.com/projects/LearnIIS7/ You can find this week’s video here.

  • Hot to get website/product reviews reflected in Google's search results using review-aggregate format

    - by BasP
    I am managing a website called Rent A Boat Amsterdam. We have a system that gathers reviews from people that have used our services and that publishes these customer reviews making them available for all website visitors. When these customer reviews are published we have placed them within the appropriate tags according to the guidelines set by Google, which you can find here. An example looks like this: <li class="" style="clear:both;"> <div class="hreview"> <div class="item" style="display:none;"><span class="fn">Boatname</span></div> <div style="border:1px solid #DEDEDE; background-color:#D9FFD4; margin:0 10px 10px 0; float:left; text-align:center; padding:10px; height:50px; width:70px;"><h1><span class="rating">10</span></h1>9-Jun-2010</div> <div> <div class="description"><p>Great canal Cruise!</p></div> <p class="reviewer vcard"><strong><span class="fn">First name Last name</span></strong></p> </div> </div> We have implemented these tags a couple of months ago, but there are no visible results in the Google SERP's. This whilst I had expected to find the reviews / ratings displayed similar to: Is anyone familiar with this topic and able to help me find the answer to the question why the review-aggregate format doesn't seem to have the desired effect?

  • Algorithm for a lucky game [on hold]

    - by Ronnie
    Assume we have the following Keno(lottery type) game: From 80 numbers(from 1 to 80), 20 are being drawn. The players choose 1 or 2 or 3..... or 12 numbers to play(12 categories). If they choose for example 4 then they win if they predict correctly a certain amount of numbers(2,3 or 4) from the 4 they have played and lose if the predict only 1 or 0 numbers. They win X times their money accordingly to some predefined factor depending on how many numbers they predict from each category. The same with the other categories. And e.g 11 out of 11 gives 250000 times your money and 12 out of 12 gives 1000000 your money. So the company would want to avoid winnings so high. Every draw by the company is being made every 5 minutes and in each draw around 120000 (let's say) different predictions(Keno tickets) are being played. Let's assume 12000 are being played in category 10 and 12000 in category 11 and also 12000 in category 12. I'm wondering if there is an algorithm to allow the company that provides the game in the 5 minutes between the drawings, to find a 20 number set, in order to avoid any "12 out of 12" and "11 out of 11" and "11 out of 12" and "10 out of 11" and "10 out of 10" winning ticket. That means is there any algorithm, where in a time of less than 1 minute approximately(in todays hardware), to be able to find a 20 number set so that none of the 12000 12 and 11 and 10 number sets that the players played(in categories 10,11 and 12) contains any winning of "12 out of 12" and "11 out of 11" and "11 out of 12" and "10 out of 11" and "10 out of 10"? Or even better the generalization of the problem: What is the best algorithm(from a perspective of minimal time), to be able to find a Y number set from numbers 1 to Z(e.g Y=20, Z=80) so that none of the X sets of K-numbers that are being played(in category K) contains more than K-m numbers from the Y-set? (Note that for Y=K and m=1 there is a practical algorithm.)

  • Are books on programming hard to understand?

    - by DarkEnergy
    I've been reading books that are extremely daunting. Accelerated C++ is by far one of the books -- that I haven't finished. I plan too, but that's another story. When reading a programming book, do you find yourself re reading a lot of the paragraphs? Sometimes it takes me like an hour to read 20 pages out of a book. Sometimes they become so daunting that it takes me all day to finish a single chapter. I think having these as e-books makes them even harder to read sometimes, since I'm so used to looking down to read a book or just looking at tangible paper. IDK, just wanting to know if reading these books becomes extremely hard, and do you find yourself rereading the most simplest paragraphs 2-3 times just to get the meaning of it because the previous paragraph left your brain hurting? http://www.it-career-coach.net/2007/03/04/are-computer-programming-books-hard-to-study/ here is a article i read on something similar to this. edit sometimes I find myself reading a whole page... then I look up and say 'wth did I just read'... I could finish a chapter in 30 minutes to an hour and feel this way too...

  • unit level testing, agile, and refactoring

    - by dsollen
    I'm working on a very agile development system, a small number of people with my doing the vast majority of progaming myself. I've gotten to the testing phase and find myself writing mostly functional level testing, which I should in theory be leavning for our tester (in practice I don't entirely...trust our tester to detect and identify defects enough to leave him the sole writter of functional tests). In theory what I should be writing is Unit level tests. However, I'm not sure it's worth the expense. Unit testing takes some time to do, more then functional testing since I have to set up mocks and plugs into smaller units that weren't design to run in issolation. More importantly, I find I refactor and redesign heavily-part of this is due to my inherriting code that needed heavy redesign and is still being cleaned up, but even once I've finished removing parts that need work I'm sure in the act of expanding the code I'll still do a decent amount of refactoring and redesign. It feels as if I will break my unit tests, forcing wasted time to refactor them as well, often due to unit test, by definition, having to be coupled so closely to the code structure. So.is it worth all the wasted time when functional tests, that will never break when I refactor/redesign, should find most defects? Do unit tests really provide that much extra defect detetection over through functional? and how does one create good unit tests that work with very quick and agile code that is modified rapidly? ps, I would be fine/happy with links to anything one considers an excellent resource for how to 'do' unit testing in a highly changing enviroment. edit: to clarify I am doing a bit of very unoffical TDD, I just seem to be writing tests on what would be considered a functional level rather then unit level. I think part of this is becaus I own nearly all of the project I don't feel I need to limit the scope as much; and part of it is that it's daunting to think of trying to go back and retroactively add the unit tests needed to cover enough code that I can feel comfortable testing only a unit without the full functionality and trust that unit still works with the rest of the units.
