• HP Pavilion dv7 dual boot with ubuntu and original win7 issues

  - by Neasy11

  I just bought a hp dv7 and I want to dual boot it with the win7 it came with and ubuntu 12.04.1. I shrunk the C partition to make room for the ubuntu one then downloaded an burnt the iso. Next I booted from the cd and followed the simple instructions until I got to the page of the install to choose the partition where all choices were greyed out and the table was completely blank and the drop down only had one choice. After researching this I found that a main problem might be that I can only have 4 primary partitions and the computer was shipped with the 4 already (system,C,recovery,hp tools). I guess my question is what is the best way to go about completing this dual boot? I have read to delete the hp tools partition or combine it with another, I just want a step by step of how to dual boot this computer, I have done plenty of computers in the past but never ran into these issues that come with an HP (should have got a dell lol)!

• How to get faster iteration times in android development

  - by Sebastian Bugiu

  I'm creating a game on the android platform that uses the resources/raw folder for assets and scripts. The problem is that every time I change something I have to rebuild the application to test the new variant. Of course this is bad for iteration times. Any ideas about what I can do to avoid rebuilding every time I change something? This *.apk format is getting on my nerves now that I have to recreate it every time I change a word in my scripts. Or at least how to make eclipse auto-rebuild every time I change something in my resources folder so that I don't have to go to Project-Build every time?

• Fan very loud in Ubuntu 12.10

  - by Jon

  I recently installed 12.10 on my Desktop PC, moving away from Windows 7. For some reason, the fan in my computer is making an enormous amount of noise (it is running at full speed constantly). Under Windows 7, the fan would slow itself down and run at an acceptable noise level. Now, it is nearly unbearable. Checked the processes, and none are taking up a huge load on the CPU. Please help as I really can't endure this noise, and I do not want to go back to Windows 7 on this box. Some specs: - Intel 2.26 duo core - ATI 4870 - 4GB - 650W power supply

• Where does node.js install to?

  - by Ash Scott

  I'm trying to install a script, which is a clone of a game, and uses node.js for it. Now, the documentation says I should copy the node.exe (windows) and put it where the clone is. Now, I can't find the node.exe ubuntu equivalent, I can't even find where it's installed?! Don't really want this hosted on a windows machine due to licensing. Here's a snipet from the doc: Download : Node.js (Install Button) Go where you are install Node.js (For Windows 8 it's C:/Programms/nodejs) Copy node.exe and paste on the clone folder Now I need to do this in ubuntu, however I can't find where node is installed to? Any ideas?

• How do I pitch ASP.NET over PHP to a potential client?

  - by roman m

  I work at a Microsoft shop doing mainly web development. We had a client who asked us to review (improve) the data model for his web app, but said that he wants to develop his app in PHP (he knows "a guy" who can do it). When I asked him why he wants to go with PHP, he gave me the standard set of arguments from the 90's: Microsoft is evil, and PHP is free Writing an ASP.NET app is more expensive (software-wise) Why would Facebook use PHP if it was a bad idea? [classic] He had a few more comments about the costs associated with going .NET. The truth is that "Microsoft is expensive" does not hold water any longer, with their "Express" suite, you can develop an ASP.NET app without paying anything for software. When it comes to hosting, you can save a few bucks with PHP over .NET, but that's a small fraction of the projected development costs (we quoted 10-15k). Going back to my question, what arguments would I give to a client in favor of ASP.NET over PHP? [please provide sources for quantitative claims]

• Does XNA/MonoGame have a text caching mechanism, or has an open source one been implemented?

  - by Casey

  I'm playing around with MonoGame, and I've noticed the SpriteFont class draws static text very inefficiently. Each time the text is drawn the spacing is recalculated. This isn't a big deal on my quad core PC, but on mobile applications it might be a problem. Before I go and program some text which caches the arrangement of its letters in an array and then feeds that array to the SpriteBatch, I would like to make sure there isn't something available to do this already, either in MonoGame itself or a class someone has implemented and made available for general use.

• Arguments for or against using Try/Catch as logical operators

  - by James P. Wright

  I just discovered some lovely code in our companies app that uses Try-Catch blocks as logical operators. Meaning, "do some code, if that throws this error, do this code, but if that throws this error do this 3rd thing instead". It uses "Finally" as the "else" statement it appears. I know that this is wrong inherently, but before I go picking a fight I was hoping for some well thought out arguments. And hey, if you have arguments FOR the use of Try-Catch in this manner, please do tell. EDIT For any who are wondering, the language is C# and the code in question is about 30+ lines and is looking for specific exceptions, it is not handling ALL exceptions.

• System that splits passwords across two servers

  - by Burning the Codeigniter

  I stumbled upon this news article on BBC, RSA splits passwords in two to foil hackers' attacks tl;dr - a (randomized) password is split in half and is stored across two separate servers, to foil hackers that gained access to either server upon a security breach. Now the main question is, how would this kind of system would be made... codespeaking, for PHP which I commonly develop on my web applications, the database password is normally stored in a configuration file, i.e. config.php with the username and password, in that case it is understandable that the passwords can be stolen if the security was compromised. However when splitting and sending the other half to the other server, how would this go on when making a communication to the other server (keeping in mind with PHP) since the other server password would be stored in a configuration file, wouldn't it? In terms of security is to keep the other server password away from the main one, just exactly how would the main server communicate, without exposing any other password, apart from the first server. This certainly makes me think...

• Utility Queries–Database Files, (and Filegroups)

  - by drsql

  It has been a while since I last posted a utility query, and today, to avoid other work I am supposed to be doing, I decided to go ahead and work on another post.  Today, I went ahead and worked on a server configuration type query. One query I find I use pretty often is the following one that lists the files in the database. In this blog I will include 3 queries.  The first will deal with files and databases, and the second runs in a database to see the files and their filegroups (If there...(read more)

• What steps/tools/apps are necessary to make local php development on a tablet viable?

  - by Tchalvak

  I do my php web development locally, as in, creating a local instance of a site and then coding it and then pushing code to servers via git/github. I'm considering getting an android tablet or ipad and a wireless keyboard for very mobile development, but I in no way want to go back to the bad old days of using ftp and syncing up code changes on a development server directly, that would be too much of a trade-off to interest me. Is there enough support for the stack to develop php websites locally on a tablet? Anyone had experience trying this sort of thing?

• Multiple domains

  - by menardmam

  I got 6 domains : company.ca and company.com (because both where free, but we are a canadian company but can do business with the rest of the world). Then, we sell sportwear because of the company name is totally unknown to the world. Our product is we have bought product specific domain : chandails.ca and t-shirt.ca as well as shorts.ca and shorts.com. So those 6 domains are mine. Now what is the best way to do? Now all are 301 redirect to the main company name (.com) or make micro-site, super simple one page optimized for just shirt and one for shorts, then tell people to know more, go to the main site. Because now, I cannot really find the benefit of the search word in domain name edge if never somebody see something in that domain... I got confused and don't find strait answer to this question.

• Tic-Tac-Toe game AI

  - by David Jones

  I'm looking into creating a simple tic tac toe/noughts and crosses game in Actionscript3 and am trying to understand the ideas behind the AI used in a game like this. I've seen some simplistic examples online but from what I've read a game tree or something like minimax is the best way to go about this. Can anyone help explain or reference any good examples of this? I've seen that there is a library called as3ds - data structures for game developers which has a number of classes that might help tie this together? Any info/examples or help is much appreciated.

• Where can I safetly search domain whois without worrying about the search engine parking on the domain immediately after the search?

  - by Evan Plaice

  There are a lot of companies that provide domain whois but I've heard of a lot of people who had bad experiences where the domain was bought soon after the whois search and the price was increased dramatically. Where can I gain access to a domain whois where I don't have to worry about that happening? Update: Apparently, the official name for this practice is called Domain Front Running and some sites go as far as to create explicit policies stating that they don't do it. This is where a domain registrar or an intermediary (like a domain lookup site) mines the searches for possibly attractive domains and then either sells the data to a third-party, or goes ahead and registers the name themselves ahead of you. In one case a registrar took advantage of what's known as the "grace period" and registered every single domain users looked up through them and held on to them for 5 days before releasing them back into the pool at no cost to themselves. Source: domainwarning.com And apparently, after ICANN was notified of the practice, they wrote it off as a coincidence of random 'domain tasting'. Source: See for yourself

• Need suggestions on how to create a website with an encrypted database.

  - by SFx

  Hi guys, I want to create a website where a user enters content (say a couple of sentences) which eventually gets stored in a backend database (maybe MySQL). But before the content leaves the client side, I want it to get encrypted using something on client like maybe javascript. The data will travel over the web encrypted, but more importantly, will also be permanently stored in the backend database encrypted. Is JavaScript appropriate to use for this? Would 256 bit encryption take too long? Also, how do you query an encrypted database later on if you want to pull down the content that a user may have submitted over the past 2 months? I'm looking for tips, suggestions and any pointers you guys may have in how to go about learning about and accomplishing this. Thanks!

• Hosting advice for a write-heavy dynamic website

  - by Rahul Rawat

  I have built a website using PHP and MySQL and now I am looking for a hosting service. I am expecting about a 1000 users registering and about 5-10k pageviews/day in a week's time. So which host should I opt for? It will let users submit contents of type blobs and submit around 10 pictures per users. I hope that traffic will increase so can justhost's or bluehost's shared hosting serve that purpose or should I go for more dedicated ones. Basically the site is write heavy and there are average 2-3 MySQL queries per page and it is quite dynamic. So depending on these requirements which web hosting will be optimal for me.

• Do I have to write a lot of boilerplate code if I keep working using Java?

  - by edem

  I'm working for a company writing ERP applications. My problem is that I have to write tons of boilerplate code. I came up with ideas to automatize/prevent the drudgery but only some of them were accepted. I have been told by the lead developer that my ideas tend to be go far afield and I should write code everyone can understand. I had a discussion about this lately and it seems to me that this kind of code ramp is within java's philosophy. I have to write lots of code to achiveve simple things not because it is necessary but because this is the way most of the people at the company think. Is this universally applicable to most of the companies out there using java or this is just my company's view? Do I have to get used to the drudgery if I keep working for java-based firms?

• SEO for images: can I use a different (cookieless) domain?

  - by Oliver

  Hello, We want to increase the value of some of our important images by means of SEO, and we want to start serving them from a different, i.e. cookieless, domain. We want to go from http://www.example.com/images/1234.jpg to http://www.example.com/germany/bavaria/landscape.jpg which can easily be done via URL rewriting. Then on the other hand, we would like to serve the image from a completely different domain, let's say http://www.examplestatic.com/germany/bavaria/landscape.jpg, to save the overhead of sending the cookie from www.example.com. Somehow I feel that this is not a good idea because I move the image away from the content by putting it on a different domain. Can anyone shed some light on this problem? Naturally, I would just use a different subdomain, e.g. img.example.com, but we already use subdomains for languages and our cookies are valid for all subdomains of example.com, so this won't help. I'd really appreciate any hints. Cheers,

• Using components in the XNA Game State Management example?

  - by Zolomon

  In the game state management example at the App Hub, they say that if you want to use components in the example you can extend the GameScreen to host other components inside itself. I'm having a very hard time trying to tie this up. I tried extending the GameScreen class by adding a public property of public List<DrawableGameCompnent> components { get; set; } and then add my components to that list when I initialize the current screen as well as looping over the components in the LoadContent, Update and Draw methods. However, this doesn't feel like the correct way to go - mainly because it doesn't work when I get to the implementation of my GameplayScreen. Any thoughts?

• "Time Control" in a 2d Platformer

  - by Woody Zantzinger

  I am making a 2d platformer where the player can press a button, and restart the level, only their previous character will also run the level at the same time, like they are traveling back in time. I know other games have done this before, and the way I have thought of doing it is to make the game character have a set of actions (Idle, Jumping, Walking Left etc.) and then detect changes in those actions and log them into a list along with the game time. So then when I need the character to run the level again on its own, I can just go through the list changing its actions at the right time. Is this the best way to do it? Does anyone have any experience in this? Thanks.

• ViewController in programming

  - by Vishwas Gagrani

  ViewController is a term for classes that handle views in a framework. This is especially used in MVC frameworks. I go through various projects, written by various programmers, who implement MVC in different ways. Especially, i get confused, about the relation between the MainView ( parent view ) and some CustomView ( widget etc) in the framework. I personally pass reference of the MainView into the ViewController to be instantiated. All the subviews of ViewController are added to that reference of MainView. Additionally, ViewController itself is added as a child of MainView. Like this : Want to know, if this is the right way to relate each other ?
