• Looking for an open source project in Python

  - by Roman Yankovsky

  I am looking for practical tasks to get experience with Python. Just reading the books and not doing any tasks in the language is not effective. I solved some problems on the Project Euler and TopCoder and it helped me to learn the syntax of the language better. But those tasks are hard algorithmically, but as a rule is quite simple from the point of view of programming. Now I'm looking for an interesting open source project in Python, participation in which will help me to better understand the OO-model of language. Although, this is my first step with Python, in general, I am an experienced programmer and I can be useful for a project. May be someone can suggest something?

• Nautilus will not launch after update to 12.10

  - by dereksalerno

  I updated to Ubuntu 12.10 today from 12.04 using the graphical update tool. Everything seemed to be fine until I went to open Nautilus, and it would not open. Bizarrely, I am able to open a file that I happen to have on my desktop, but when I click on the launcher, it never opens. When I enter 'nautilus' in the terminal, I get this: (nautilus:8557): Gdk-CRITICAL **: gdk_x11_display_get_xdisplay: assertion `GDK_IS_DISPLAY (display)' failed zsh: segmentation fault (core dumped) nautilus I am not a total novice with ubuntu or linux, but all I can tell is that there is some problem with X. Can someone please point me in the right direction as far as fixing this? I really don't want to have to do a fresh install. Thank you very much.

• Even EA's Have Bad Days - it's Time to Reset

  - by Pat Shepherd

  I saw this article and thought I'd share it because, even we EA's have bad days and the 7 points listed are a great way for you to hit the "reset" button. From Geoffrey James on INC.COM, here are 7 ways to change your view of things when, say, you are hitting a frustration point coordinating stakeholders to agree on an approach (never happens, right?) Positive Thinking: 7 Easy Ways to Improve a Bad Day http://www.inc.com/geoffrey-james/positive-thinking-7-easy-ways-to-improve-a-bad-day.html To paraphrase:          You can decide (in an instant) to change patterns of the past          Believe in (or even visualize) good things happening, and they will          Keep a healthy perspective on the work-life / life-life continuum (what things REALLY matter in the big scheme of things)                  Focus on the good (the laws of positive-attraction apply)

• IValidatableObject vs Single Responsibility

  - by Boris Yankov

  I like the extnesibility point of MVC, allowing view models to implement IValidatableObject, and add custom validation. I try to keep my Controllers lean, having this code be the only validation logic: if (!ModelState.IsValid) return View(loginViewModel); For example a login view model implements IValidatableObject, gets ILoginValidator object via constructor injection: public interface ILoginValidator { bool UserExists(string email); bool IsLoginValid(string userName, string password); } It seems that Ninject, injecting instances in view models isn't really a common practice, may be even an anti-pattern? Is this a good approach? Is there a better one?

• How to mount a disk that supports Samba sharing (Using Disk Utility)

  - by Luis Alvarado - The Wolverine

  This might be a tricky question but here is the objective: Manage to mount a disk/partition automatically without (or at least trying to avoid): Editing any Samba configuration file Editing the fstab file and to make it a little bit harder, this needs to be done with the options for "Mount Options" in the Disk Utility: Note that if left as it is, every time a user mounts a partition/disk and then tries to share a folder in it, Windows users can see the share but can not access it, with a permission warning appearing. The point of all of this is to find the most user friendly (Oriented towards a GUI) way of enabling a partition to be mounted, accessed by the local user (Read, Write, Execute) and to also be able to, when needed, share a folder and have no problems reading/writing on it from another Ubuntu/Windows/Mac remote computer (Assuming both are in the same LAN network).

• Omni-directional shadow mapping

  - by gridzbi

  What is a good/the best way to fill a cube map with depth values that are going to give me the least amount of trouble with floating point imprecision? To get up and running I'm just writing the raw depth to the buffer, as you can imagine it's pretty terrible - I need to to improve it, but I'm not sure how. A few tutorials on directional lights divide the depth by W and store the Z/W value in the cube map - How would I perform the depth comparison in my shadow mapping step? The nvidia article here http://http.developer.nvidia.com/GPUGems/gpugems_ch12.html appears to do something completely different and use the dot of the light vector, presumably to counter the depth precision worsening over distance? He also scales the geometry so that it fits into the range -.5 +.5 - The article looks a bit dated, though - is this technique still reasonable?

• The concept of virtual host and DNS

  - by Subhransu

  I have a dedicated server and a mydomain.com (bought from a hosting company). I want to host a website from my dedicated server with the domain mydomain.com i.e. when I enter mydomain.com from browser it should point to the IP(let's say X.X.X.X) of dedicated server(and a particular folder inside it). I have some following queries: In Server I know I need to edit some of the files (like: host or hostname file) in the server but I do not know what exact file I need to edit. How to add a Site enable or Site available in apache2 ? In Hosting Company control Panel Which records to add (A or cname or anyother)? Where Should I add DNS(in dedicated server section or domain name section)? How it is going to affect the behaviour of the domain? in short the question is: How the virtual host works & how to add DNS?

• Acer Revo (ION platform) + Maverick + 5.1 surround over HDMI

  - by Oli

  I've had a turbulent relationship with my media centre box. Every upgrade I perform on it seems to bring a brand new set of audio issues (the opposite of my desktop where things seem to get better and better). It's a Acer Revo 3600. That's basically an low-end Intel Atom chip with a Nvidia 9400M onboard. On paper that's perfect for something like a media centre. But having just upgraded to Maverick, the sound properties box only wants to offer me stereo sound over HDMI. The exact setup goes: Revo - Onkyo AV receiver - LG TV. The Onkyo box strips off the audio (supporting 7.1 -- though we're only using 6 speakers) and feeds the video onto the TV. I'd like to get to a point where Ubuntu thinks it's doing 5.1 over HDMI, upmixing stereo to 6ch and supporting DTS/AC3 (through Boxee). I've had this working before but it's frankly been a bit of a hacktastrophe. The audio chip is recognised as Nvidia MCP79/7A HDMI in alsamixer if that helps.

  - by Kris Everett

  I'm trying to install Ubuntu. I put Ubuntu on a USB flash drive using the WUBI installer. I get to where it finishes the install and it wants me to reboot. But when I reboot and then select Ubuntu, I get a black screen that says GNU GRUB version 1.99-21ubuntu3 Minimal BASH-like editing is supported. for the first word. TAB lists possible command completions. Anywhere else TAB lists possible device or file completions. Grub> When I type in some commands it says "Kernel not specified" and the rest of the commands give no feed back what so ever. What did i do wrong? Can anyone point me in the right direction. Please help this is very frustrating any help would be useful.

• Why Garbage Collection if smart pointers are there

  - by Gulshan

  This days, so many languages are garbage collected. Even it is available for C++ by third parties. But, C++ has RAII and smart pointers. So, what's the point of using garbage collection? Is it doing something extra? And in other languages like C#, if all the references are treated as smart pointers(keeping RAII aside), by specification and by implementation, will there be still any need of garbage collectors? If no, then why this is not so?

• To have multiple sites with similar content on the same server but different IPs?

  - by Eugene

  I have 7 different sites on the same dedicated server. Two major sites have different IPs, and 5 small share the same IP. About first 2 they have similar content, but not the same. Basically they have different: URLs Titles Meta Data But they both have the same niche. I was thinking about two strategies. One is to move one of the sites (from 2 first one) on different server or move 5 other sites on different server. But I'm not sure which way is better. My questions are: Wouldn't be better from SEO stand point, to move those 2 sites on different servers? Does it worth it to spend for additional server? Do you know if Google penalize sites for similar content on the same server with different IPs?

• Workflows in SharePoint 2013, Part 1

  - by Sahil Malik

  SharePoint 2010 Training: more information Hooray! My latest article is now online on code-magazine. And this time, it’s about “Workflows in SharePoint 2013” – and there will be a part 2 of this next month. Here is a starter .. If we have been friends for a while, you must know my opinions about workflows in SharePoint 2010 and SharePoint 2007. I didn’t think they were very good, especially from a performance and scalability point of view. Frankly I think Microsoft should have called them “workslows.” Though, I don’t think it was the implementation in SharePoint that was the issue, it was fundamental issues with Workflow Foundation, compounded by the nature of SharePoint that acerbated the issues. Well, I am happy to say that Workflows in SharePoint 2013 are something I feel quite comfortable recommending to anyone, and I hope to make that case in this article. Read more ..

• Using AntiXss As The Default Encoder For ASP.NET

  Scott Guthrie recently wrote about the new <%: %> syntax for HTML encoding output in ASP.NET 4. I also covered the topic of HTML encoding code nuggets in the past as well providing some insight into our design choices for the approach we took. A commenter to Scotts blog post asked, Will it be possible to extend this so that is uses libraries like AntiXSS instead? See: http://antixss.codeplex.com/ The answer is yes! ASP.NET 4 includes a new extensibility point which allows you to replace...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. Take a look: here.

• what is best book to learn optimized programming in java [closed]

  - by Abhishek Simon

  Possible Duplicate: Is there a canonical book for learning Java as an experienced developer? Let me elaborate a little: I used to be a C/C++ programmer where I used data structure concept like trees, queues stack etc and tried to optimize as much as possible, minimum no. of loops, variables and tried to make it efficient. It's been a couple of years that I started writing java codes, but it is simply not that efficient in terms of performance, memory intensive etc. To the point: I want to enter programming challenges using java so I need to improve my approach at things I program. So please suggest me some books that can help me learn to program better and have a chance in solving challenges in programming.

• Developing payment gateway.

  - by kmaxat

  Hello, I have an idea of developing internet payment gateway similar to PayPal or Webmoney. Since i'm only sophomore at Computer Science, and i've only taken intermediate programming classes, i've no idea where to search for general information about this topic. I do understand that this kind of project is CLEARLY too much to handle for sophomore. Since, it's forum for Pro Webmasters, and probably some of you can point direction of study. What book/source/article would you suggest to read to understand fundamentals of internet payment? What book/source/article would you suggest to read to understand fundamentals internet security? What language is most commonly used for developing payment security of website? I appreciate any help. Thank you.

• SEO consequences for merging country sites in a .com

  - by Pekka

  I am in the process of refactoring a number of rental portals I've built for a company with locations in Austria, Germany, Switzerland, and the Netherlands. Instead of the current setting of each country site running under its own domain name: www.companyname.de www.companyname.ch www.companyname.at I would love to merge them all in this way: www.companyname.com/de www.companyname.com/ch www.companyname.com/at with the country TLDs doing a 301 redirect to the respective .com address. However, I have been repeatedly told not to do this due to likely problems with SEO - the business is very SEO dependent, and being a rental chain, needs to be strong in local results. So the question is: Is there an unavoidable hit in Search Engine Optimization when redirecting to a central .com domain? What measures can be taken to soften the blow? What comes to my mind is explicitly specifying a lang attribute in the html tag. Are there any other ways to specifically point out geographical location for sub-directories?

• Help with creating symbolic link

  - by user1737794

  I'm a little bit confused with how the symbolic links work. I hope someone can guide me in the right direction. I want to put a demo online from our software, which normally only runs locally on a Mac Mini. So I put all the files in the var/www from my Ubuntu 12.04 server installation. There are a lot of hardcoded links in the software which point to "/Applications/XAMPP/xamppfiles/htdocs/narrowcasting" Of course I can change all these code on my html/php files in /var/www, but that would be quite annoying. I hope I can fix this by creating a symbolic link. For example I have a directory called thumb in /var/www/thumb. The php code is trying to put a image in /Applications/XAMPP/xamppfiles/htdocs/narrowcasting/thumb. Can anyone give me a tip how to achieve this with a symbolic link? Thanks in advance.

• JavaOne and Oracle Open World Community Run - Monday, Oct 1, 6:17am PT

  - by arungupta

  Following the tradition from last year, inviting all JavaOne and Oracle Open World attendees to run with me in one of the 10 best cities to run in the US. The running route will start at Ferry Plaza on Embarcadero, go through Fisherman's Wharf, straight up Hyde St, couple of loops around Crooked Street and then back the same route to end at Ferry Plaza. Here is the complete clickable map: The Hyde Street (~300ft in 0.75 miles) and Lombard (~200 ft in 0.15 mile) are challenging elevations and you may cover them once only. Alternatively you may take a simpler route out-and-back by running further up to Marina and Crissy Field. When ? Monday, Oct 1, 2012 I plan to leave at 6:17am PT from the starting point and certainly hope you can join me. Oracle is doing several things to keep Oracle Open World and JavaOne sustainable and reduce the conference footprint. Lets do our share to keep the conference green! Of course, don't forget the Geek Bike Ride is tomorrow.

• Structuring a rails application with static data

  - by Morten

  I'm working on a rails application, and so far I've focused on the api and the functionality. But now I'm more and more reaching a point where I will want to add static content, descriptions of the software and help information. Information that is generally in a CMS system. How do I in the best way structure this so I can still work with the application. Yet maintaining the look and feel of the rails application? Do write a CMS in my app? That seems a bit far fetched. Are there any Gems that do this? What is the de facto standard for architecting this scenario?

• Rotate view matrix based on touch coordinates

  - by user1055947

  I'm working on an Android game where I need to rotate the camera around the origin based on the user dragging their finger. My view matrix has initial position of sitting on the negative z and facing origin. I have succeeded in moving the camera through rotation left or right, up or down based on the user dragging the finger, but my problem is obviously that after I drag my finger up/down and rotate say 90 degrees so my intial position of -z is now +y and still facing origin, if I drag my finger left/right I want to rotate from +y to +x, but what happens is it rotates around the pole +y. This is to be expected as I am mapping 2D touch drag coords to 3D space, but I dont know where to start trying to do what I want. Perhaps someone can point me in the right direction, I've been googling for a while now but I don't know what I want to do is called! Edit __ What I was looking for is called an ArcBall, google it for lots of info on it.

• How can I get data off of a (probably) very corrupt drive?

  - by Mercury1964

  So, my younger brother wanted my help today. Apparently, he was helping a friend install Ubuntu to his laptop, and midway through the install (on a filled hard-drive with Windows 8, from the liveusb thing): 1) They realized that they had chosen "Erase and install" accidentally and decided the best course of action was to (in the middle of an install, remember) 2) Force shutdown the computer. After I had replaced my eyeballs back into their sockets, my bro asked if I could do anything about his friend's data, which he wanted back. This, however, drifts out of my normal comfort zone. I know this about the install: 1) It was on a fairly new Windows 8 laptop, so it had whatever filesystem it uses nowadays on the entire drive 2) They didn't choose the "zero out drive data" option 3) They stopped the install at some point (not sure if before or after wipe) I can imagine that it now has two corrupted filesystems on it (whatever Windows 8 was on and ext3) and that some of the data still exists (assuming it wasn't overwritten already). Is there anything that can be done for whatever data is left on the drive?

• How do you react to non-programmers with ideas of 'The Next Big Thing' ?

  - by jiceo

  Recently and quite often, people with no programming background come and say they have this great idea that can be the next big thing and that the idea(s) is worth a fortune by itself. Then as they know I'm a programmer, they ask me if I'm willing to "code it up" for them or find someone willing to do it for next to nothing. Judging from the enthusiasm, it's like they're drunk on their idea and that that by itself is the most important thing, but they just need a programmer. My response to them, depending on my mood and their general attitude towards what we do, is something along the lines of: "Having the core of an idea is one thing. Developing it to the point that it becomes a platform that changes the world in which it lives is another, and you're going to be willing to pay proportionately to how big you think your idea is worth." Have you been approached by these business type entrepreneurs (with no technical/developer's knowledge) with such a proposal and how do you react to them?
