• Ruby on Rails - How can I start? [closed]

  - by Mashael

  I have misconception in understanding the relationship between Ruby language and Ruby on Rails Framework. Because of 'I am an absolute beginner' in web development I have no idea if I have to grasp the fundamentals of Ruby before I go with Ruby on Rails! I also want to ask who is behind both Ruby and Ruby on Rails. Who is developing both? And is there intention to improve its speed? In short, I'd like to know the road map to effectively beginning learning Ruby on Rails. Furthermore, I'm wondering about the next steps in improving Ruby and Rails and who are the main role players in improving them?

• svn connection timeout

  - by Tom celic

  I have Ubuntu 12.04 running in virtual box inside Windows 7. I have the network adapter set as NAT and everything networking wise seems to be running smoothly (internet / git ect.). However, for some reason, svn always times out when i.e michael@michael-VirtualBox:~/Documents/deleteme$ svn co svn://svn.openwrt.org/openwrt/trunk/ svn: Can't connect to host 'svn.openwrt.org': Connection timed out Somebody suggested to me that I might need to change what ports svn uses. Does anybody have any idea how to diagnose / solve the problem? Thanks!

• SQL SERVER – Simple Example of Snapshot Isolation – Reduce the Blocking Transactions

  - by pinaldave

  To learn any technology and move to a more advanced level, it is very important to understand the fundamentals of the subject first. Today, we will be talking about something which has been quite introduced a long time ago but not properly explored when it comes to the isolation level. Snapshot Isolation was introduced in SQL Server in 2005. However, the reality is that there are still many software shops which are using the SQL Server 2000, and therefore cannot be able to maintain the Snapshot Isolation. Many software shops have upgraded to the later version of the SQL Server, but their respective developers have not spend enough time to upgrade themselves with the latest technology. “It works!” is a very common answer of many when they are asked about utilizing the new technology, instead of backward compatibility commands. In one of the recent consultation project, I had same experience when developers have “heard about it” but have no idea about snapshot isolation. They were thinking it is the same as Snapshot Replication – which is plain wrong. This is the same demo I am including here which I have created for them. In Snapshot Isolation, the updated row versions for each transaction are maintained in TempDB. Once a transaction has begun, it ignores all the newer rows inserted or updated in the table. Let us examine this example which shows the simple demonstration. This transaction works on optimistic concurrency model. Since reading a certain transaction does not block writing transaction, it also does not block the reading transaction, which reduced the blocking. First, enable database to work with Snapshot Isolation. Additionally, check the existing values in the table from HumanResources.Shift. ALTER DATABASE AdventureWorks SET ALLOW_SNAPSHOT_ISOLATION ON GO SELECT ModifiedDate FROM HumanResources.Shift GO Now, we will need two different sessions to prove this example. First Session: Set Transaction level isolation to snapshot and begin the transaction. Update the column “ModifiedDate” to today’s date. -- Session 1 SET TRANSACTION ISOLATION LEVEL SNAPSHOT BEGIN TRAN UPDATE HumanResources.Shift SET ModifiedDate = GETDATE() GO Please note that we have not yet been committed to the transaction. Now, open the second session and run the following “SELECT” statement. Then, check the values of the table. Please pay attention on setting the Isolation level for the second one as “Snapshot” at the same time when we already start the transaction using BEGIN TRAN. -- Session 2 SET TRANSACTION ISOLATION LEVEL SNAPSHOT BEGIN TRAN SELECT ModifiedDate FROM HumanResources.Shift GO You will notice that the values in the table are still original values. They have not been modified yet. Once again, go back to session 1 and begin the transaction. -- Session 1 COMMIT After that, go back to Session 2 and see the values of the table. -- Session 2 SELECT ModifiedDate FROM HumanResources.Shift GO You will notice that the values are yet not changed and they are still the same old values which were there right in the beginning of the session. Now, let us commit the transaction in the session 2. Once committed, run the same SELECT statement once more and see what the result is. -- Session 2 COMMIT SELECT ModifiedDate FROM HumanResources.Shift GO You will notice that it now reflects the new updated value. I hope that this example is clear enough as it would give you good idea how the Snapshot Isolation level works. There is much more to write about an extra level, READ_COMMITTED_SNAPSHOT, which we will be discussing in another post soon. If you wish to use this transaction’s Isolation level in your production database, I would appreciate your comments about their performance on your servers. I have included here the complete script used in this example for your quick reference. ALTER DATABASE AdventureWorks SET ALLOW_SNAPSHOT_ISOLATION ON GO SELECT ModifiedDate FROM HumanResources.Shift GO -- Session 1 SET TRANSACTION ISOLATION LEVEL SNAPSHOT BEGIN TRAN UPDATE HumanResources.Shift SET ModifiedDate = GETDATE() GO -- Session 2 SET TRANSACTION ISOLATION LEVEL SNAPSHOT BEGIN TRAN SELECT ModifiedDate FROM HumanResources.Shift GO -- Session 1 COMMIT -- Session 2 SELECT ModifiedDate FROM HumanResources.Shift GO -- Session 2 COMMIT SELECT ModifiedDate FROM HumanResources.Shift GO Reference: Pinal Dave (http://blog.sqlauthority.com) Filed under: Pinal Dave, SQL, SQL Authority, SQL Performance, SQL Query, SQL Scripts, SQL Server, SQL Tips and Tricks, T SQL, Technology Tagged: Transaction Isolation

• Developer Training – A Conclusive Summary- Part 5

  - by pinaldave

  Developer Training - Importance and Significance - Part 1 Developer Training – Employee Morals and Ethics – Part 2 Developer Training – Difficult Questions and Alternative Perspective - Part 3 Developer Training – Various Options for Developer Training – Part 4 Developer Training – A Conclusive Summary- Part 5 We have now reached the end of our series about developer training.  I hope you have come away thinking that training is the best way to advance in your company and that you are looking for training opportunities right now.  If you’re still not convinced here are a few things to keep in mind:  Training benefits the employer and the employee. A well trained employee is a happy employee, and a happy employee is more efficient and productive. Training an employee might be expensive, but it is less expensive than hiring a new person. Whether you are looking at him from the employee’s or the company’s point of view, there are always advantages to training. A Broader View This series is definitely written for Developer Training but it is not limited to developers only. There are IT Pro, System Admins, DBAs as well many other technology professionals; this article series is for all professionals in the world. The concepts and take away will remain common across all the platform and regardless of technology affiliation. Pass the Knowledge If I have to pick one advise which is extremely important related to training, I will pick – pass the knowledge. Once you have decided in favor of training, there is more to it than simply showing up and staying awake.  It is always a good idea to take notes – at the very least it will help you stay awake, but they will often serve as a good way to remember your training when you go back to work.  You can also use them to pass your new knowledge on to fellow employees, which can be very fun and rewarding. Right Place, Right Time and Right Training There are so many ways to get developer training.  In-person and on the job training is easy to come by and is the most usual type of training, but don’t overlook my favorite type of training: On Demand.  Being able to learn at your own pace, own place and on your own time will make training a realistic goal for almost every employee. I can think of nothing more important in life than furthering your education.  Especially when you work in a field that is constantly changing – like technology.  Whether you like it or not, training is incredibly important.  That is why I feel it is so important to receive training.  And because there are so many different training formats – live, online, through books, through people – I am certain that we all can find a way to be trained that best suits our goals and personalities. The Teacher Within If you think of anyone who is a master of the technology field or an incredibly successful developer (the obvious examples that spring to mind are Steve Jobs or Bill Gates), you will also find a teacher.  Both these individuals spent their lives developing better technology, but also educating other developers and the public about how to use these technologies and how it can change your life for the better.  I think that we all should strive to be like these wonderful teachers.  We might not be able to change the world, but we can certainly change a few lives around us. Even if we never turn into trainers ourselves , being trained as a student can be a good exercise.  We learn a lot and become better employees – and it would not be a stretch to say that this makes us better individuals, as well. Final Say I think learning and growing in your chosen field is not only a good idea, career-wise, but can be fun, too!  I for one never feel more alive than when I am learning about something I am really passionate about.  I think my job title – technology evangelist – explains how enthusiastic I am about this subject.  But please don’t think that I am thinking of this as someone who wants to train and educate others (although this is also one of my passions).  I am also a passionate student.  I enjoy learning new things and am always on the lookout for new ways to learn and new people to learn from.

• How to enable 3D acceleration under VMware workstation 8, Ubuntu 11.10 host, Ubuntu 11.10 guest

  - by Yan Zhou

  I saw there are similar questions, but I don't think they answer exactly my questions. Did anyone managed to get 3D acceleration work under VMWare workstation 8? I have VMware 8.01 installed on Ubuntu 11.10. The guest I am trying is also Ubuntu 11.10. I manually installed vmware-tools and it went well, except the X-config part was skipped as it said the distribution driver is used. The guest runs well but it seems fall back to 2D mode. Does any one has any idea how to enable 3D acceleration under VMWare workstaion with Linux guest?

• integration of dynamic forms for 3rd party web apps

  - by afr0

  I've a custom web forms definition interface where I user can define bespoke web forms and those webforms are then rendered on the other part of the my web app. It works well as I can render and submit my forms dynamically. However I have a scenario where there will be different 3rd party apps should be interacting with my custom forms. So the quesion arises how can I have my client side web forms and the fields within to work with the 3rd party interfaces on the fly. Any idea in that regard or best practice will be highly appreciated.

• How to introduce web development to non-programmers?

  - by Gulshan

  Once one of my non-programmer friends asked, "I have a cool website idea that I don't want to share. Rather I want to develop it on my own. So, I want to learn web development. Tell me what to do?" And sometimes many other people asked about how to start with web development as a profession. But they are non-programmers or not from Computer Science background. What should I suggest to them? Learning programming from the scratch? Or using CMS-like tools? Or anything else?

• ATI graphics card overriding onboard Intel graphics

  - by Patrick

  I have an ATI graphics card with an AGP connection and a DVI port, and an Intel graphics processor on the motherboard with a VGA port. I have two monitors. When the graphics card is unplugged, I get this from lspci: 00:00.0 Host bridge: Intel Corporation 82G33/G31/P35/P31 Express DRAM Controller (rev 10) 00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 10) When it is attached, I get this: 00:00.0 Host bridge: Intel Corporation 82G33/G31/P35/P31 Express DRAM Controller (rev 10) 01:00.0 VGA compatible controller: ATI Technologies Inc RV380 [Radeon X600 (PCIE)] 01:00.1 Display controller: ATI Technologies Inc RV380 [Radeon X600] Note the absence of 00:02.0 - this is apparently causing the VGA monitor to say "No Signal" and the only the DVI display to show up in the list. I checked for problems in xorg.conf... there isn't one. I have no idea how to build one.

• I don't get object-oriented programming

  - by Joel J. Adamson

  Note: this question is an edited excerpt from a blog posting I wrote a few months ago. After placing a link to the blog in a comment on Programmers.SE someone requested that I post a question here so that they could answer it. This posting is my most popular, as people seem to type "I don't get object-oriented programming" into Google a lot. Feel free to answer here, or in a comment at Wordpress. What is object-oriented programming? No one has given me a satisfactory answer. I feel like you will not get a good definition from someone who goes around saying “object” and “object-oriented” with his nose in the air. Nor will you get a good definition from someone who has done nothing but object-oriented programming. No one who understands both procedural and object-oriented programming has ever given me a consistent idea of what an object-oriented program actually does. Can someone please give me their ideas of the advantages of object-oriented programming?

• How to build a game like HaxBall?

  - by Cengiz Frostclaw

  I'm a coder interested in game development, and I want to build a very simple p2p (real time) game. The perfect example for this is haxball. The client/server model doesn't matter, it could be like haxball (i.e. the room creator is the host) or changing host, or the server is host (if there is such a thing) I just want to learn the basics to create a field where players can move their characters in real time. So where should I start? Please guide me into the right direction. And with examples please. I found out that RTMFP does what I seek, but how do I use it? I know ActionScript 3.0, but no idea how to setup a multiplayer game. Please help ! Thanks in advance.

• HTG Explains: Why You Shouldn’t Use a Task Killer On Android

  - by Chris Hoffman

  Some people think that task killers are important on Android. By closing apps running in the background, you’ll get improved performance and battery life – that’s the idea, anyway. In reality, task killers can reduce your performance and battery life. Task killers can force apps running in the background to quit, removing them from memory. Some task killers do this automatically. However, Android can intelligently manage processes on its own – it doesn’t need a task killer.

I have tried Subscribe2 (seems to send some, but I have no idea how many) as well as a few Newsletter plugins. I either run out of memory trying to add 40K entries to the mail queue, or I error out trying to add 40K emails in the BCC of the email being sent.

• How do you organize your projects?

  - by Sergio Tapia

  Do you have any particular style of organizing projects? For example, currently I'm creating a project for a couple of schools here in Bolivia, this is how I organized it: TutoMentor (Solution) TutoMentor.UI (Winforms project) TutoMentor.Data (Class library project) How exactly do you organize your project? Do you have an example of something you organized and are proud of? Can you share a screenshot of the Solution pane? In the UI area of my application, I'm having trouble deciding on a good schema to organize different forms and where they belong. Edit: What about organizing different forms in the .UI project? Where/how should I group different form? Putting them all in root level of the project is a bad idea.

  Thanks to Marcel van der Holst for providing this great information on the use of Trace Flag 610. This trace flag can be used to have minimal logging into a b tree (i.e. clustered table or an index on a heap) that already has data. It is a trace flag because in testing they found some scenarios where it didn’t perform as well. Marcel explains why below. “ TF610 can be used to get minimal logging in a non-empty B-Tree. The idea is that when you insert a large amount of data, you don't want to...(read more)

• How can a code editor effectively hint at code nesting level - without using indentation?

  - by pgfearo

  I'm writing an XML text editor that provides 2 view options for the same XML text, one indented (virtually), the other left-justified. The motivation for the left-justified view is to help users 'see' the whitespace characters they're using for indentation of plain-text or XPath code without interference from indentation that is an automated side-effect of the XML context. I want to provide visual clues (in the non-editable part of the editor) for the left-justified mode that will help the user, but without getting too elaborate. I tried just using connecting lines, but that seemed too busy. The best I've come up with so far is shown in a mocked up screenshot of the editor below, but I'm seeking better/simpler alternatives (that don't require too much code). [Edit] Taking the heatmap idea (from: @jimp) I get something like this: or even these alternates:

• Simple Java networking game engine [on hold]

  - by Florian Peschka

  I want to create a simple java networking game and search a networking engine that eases use of sockets etc. I have already read some questions on here and the internet about java networking for games, but many of them were over 10 years old or not really answered. I have no idea whatsoever about what exactly I need to send in terms of messages, but I figured simple strings or integers will be enough for my purposes. It's basically a peer to peer game, so I don't need a centralized server structure. Messaging doesn't have to have an extremely low ping, yet of course all players need to have a synchronized view. What are the possibilities I have here?

• Umbraco Developer 's Christmas Office :)

  - by Vizioz Limited

  This weekend my colleague and I decided it was a good idea to decorate our office for Christmas, it's quite difficult to actually photograph it to it's full effect, but you'll have to take our word for it, it looks pretty Christmasy :) We have a 7' Tree covered in lights and decorations, lights around our PC's, tinsel everywhere we could fit it, and even large snow flakes hanging from the ceiling..You'd think we have no work on, but if fact it's the opposite we're manically busy! But hey, it's a bit of fun and it seems to be cheering everyone up in this otherwise rather Dull Regus Serviced Office ;-)We can definitely recommend doing something a bit different, as it's got us noticed and we've already won enough extra work from companies in the building to pay for our office for a year, not bad :)So here's a photo of our office, has anyone else decorated their office? I'd be happy to update this post with any good Christmas office photos that you send me!Happy Christmas all!Chris

• Alpha interpolation in a pixel shader

  - by c4sh

  How does the interpolation in a fragment shader work when it comes to the alpha parameter? I'm programming a shader with SharpDX, DirectX11. My idea is to interpolate 2 3d points of a segment, so that I'll have the position interpolated in between in the pixel shader. But I want to know what happens with the alpha parameter when that position is blocked by another polygon. For instance, if alpha is 1.0 at the left end of my segment and 0.0 at the other one. What is the value of alpha in the middle, 0.5? Or does it depend on the visibility at that point (meaning it could be, for instance, 1.0 OR 0.0 depending on if that part of the segment is hidden by a poolygon?

• Static vs Singleton in C# (Difference between Singleton and Static)

  - by Jalpesh P. Vadgama

  Recently I have came across a question what is the difference between Static and Singleton classes. So I thought it will be a good idea to share blog post about it.Difference between Static and Singleton classes:A singleton classes allowed to create a only single instance or particular class. That instance can be treated as normal object. You can pass that object to a method as parameter or you can call the class method with that Singleton object. While static class can have only static methods and you can not pass static class as parameter.We can implement the interfaces with the Singleton class while we can not implement the interfaces with static classes.We can clone the object of Singleton classes we can not clone the object of static classes.Singleton objects stored on heap while static class stored in stack.more at my personal blog: dotnetjalps.com
