• ubuntu12.04 hangs at checking battery state

  - by crystalbass17

  My 12.04 system hangs at "Checking battery state". At this stage, no commands work eg: ctrl+alt+f1, alt+f5. I ran recovery mode, I ran the command sudo mount -o remount, rw sudo dpkg-reconfigure gdm and gdm was the only one installed so I didn't get a GUI screen. I have an integrated graphics card "Intel Corporation Mobile 4 chipset Integrated Graphics Controller (rev 07)". So I cannot install nvidia drivers as everyone else suggests. I have gone through several similar questions but everyone suggests reconfiguring gdm or reinstalling graphic drivers. I did sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get upgrade to get the latest x-swat drivers. The system still hung at the same line. The other option is to reinstall ubuntu, which is out of the question, since we have a very specific install for our project where the settings are very hard to duplicate. Suggestions/Comments welcome.

• Software licensing template that gives room for restricting usage to certain industries/uses of software/source

  - by BSara

  *Why this question is not a duplicate of the questions specified as such: I did not ask if there was a license that restricted specific uses and I did not ask if I could rewrite every line of any open source project. I asked very specifically: "Does there exist X? If not, can I Y with Z?". As far as I can tell, the two questions that were specified as duplicates do not answer my specific question. Please remove the duplicate status placed on the question. I'm developing some software that I would like to be "semi" open source. I would like to allow for anyone to use my software/source unless they are using the software/source for certain purposes. For example, I don't want to allow usage of the software/source if it is being used to create, distribute, view or otherwise support pornography, illegal purposes, etc. I'm no lawyer and couldn't ever hope to write a license myself nor do I have to time to figure how to best do this. My question is this: Does there exist a freely available license or a template for a license that I can use to license my software under they conditions explained above just like one can use the Creative Commons licenses? If not, am I allowed to just alter one of Creative Commons licenses to meet my needs?

• Should you create a class within a method?

  - by Amndeep7

  I have made a program using Java that is an implementation of this project: http://nifty.stanford.edu/2009/stone-random-art/sml/index.html. Essentially, you create a mathematical expression and, using the pixel coordinate as input, make a picture. After I initially implemented this in serial, I then implemented it in parallel due to the fact that if the picture size is too large or if the mathematical expression is too complex (especially considering the fact that I made the expression recursively), it takes a really long time. During this process, I realized that I needed two classes which implemented the Runnable interface as I had to put in parameters for the run method, which you aren't allowed to do directly. One of these classes ended up being a medium sized static inner class (not large enough to make an independent class file for it though). The other though, just needed a few parameters to determine some indexes and the size of the for loop that I was making run in parallel - here it is: class DataConversionRunnable implements Runnable { int jj, kk, w; DataConversionRunnable(int column, int matrix, int wid) { jj = column; kk = matrix; w = wid; } public void run() { for(int i = 0; i < w; i++) colorvals[kk][jj][i] = (int) ((raw[kk][jj][i] + 1.0) * 255 / 2.0); increaseCounter(); } } My question is should I make it a static inner class or can I just create it in a method? What is the general programming convention followed in this case?

• New Feature! Automatic Categories for Geekswithblogs.net

  - by Jeff Julian

  One of the features we have been working on is a way to categorize posts without the need of all our bloggers getting on the same page with what categories we have and making them select the categories.  Johnny Kauffman, one of our team members at AJI Software, developed what we call the Sherlock Project over the past few months.  Sherlock is a category suggestion engine based on the content within the posts.  Now, after a post is published, Sherlock will investigate the content and come up with the suggested categories that content fits in.  This will now allow you to go to the specific topics you are interested in and see all the related posts. This is just the beginning, so many more opportunities will arise now that we have our content organized.  One of the first features I will be adding is RSS feeds for each category and sub category.  If you are into ALM, we will have a feed for that! I hope you enjoy these and the engine will continue to get better as we start testing the data.  I hope you are as excited about this as I am :D.  Technorati Tags: Geekswithblogs.net,Categories,Sherlock

• Languages like Tcl that have configurable syntax?

  - by boost

  I'm looking for a language that will let me do what I could do with Clipper years ago, and which I can do with Tcl, namely add functionality in a way other than just adding functions. For example in Clipper/(x)Harbour there are commands #command, #translate, #xcommand and #xtranslate that allow things like this: #xcommand REPEAT; => DO WHILE .T. #xcommand UNTIL <cond>; => IF (<cond>); ;EXIT; ;ENDIF; ;ENDDO LOCAL n := 1 REPEAT n := n + 1 UNTIL n > 100 Similarly, in Tcl I'm doing proc process_range {_for_ project _from_ dat1 _to_ dat2 _by_ slice} { set fromDate [clock scan $dat1] set toDate [clock scan $dat2] if {$slice eq "day"} then {set incrementor [expr 24 * 60]} if {$slice eq "hour"} then {set incrementor 60} set method DateRange puts "Scanning from [clock format $fromDate -format "%c"] to [clock format $toDate -format "%c"] by $slice" for {set dateCursor $fromDate} {$dateCursor <= $toDate} {set dateCursor [clock add $dateCursor $incrementor minutes]} { # ... } } process_range for "client" from "2013-10-18 00:00" to "2013-10-20 23:59" by day Are there any other languages that permit this kind of, almost COBOL-esque, syntax modification? If you're wondering why I'm asking, it's for setting up stuff so that others with a not-as-geeky-as-I-am skillset can declare processing tasks.

  Hi i have following code and it is enough just if i click on blue window then cpu goes to 100% for like at least one minute even with my i7 4 cores. I just check even with empty project and is the same !!! public class Game1 : Microsoft.Xna.Framework.Game { GraphicsDeviceManager graphics; SpriteBatch spriteBatch; private Texture2D cursorTex; private Vector2 cursorPos; GraphicsDevice device; float xPosition; float yPosition; public Game1() { graphics = new GraphicsDeviceManager(this); Content.RootDirectory = "Content"; } protected override void Initialize() { Viewport vp = GraphicsDevice.Viewport; xPosition = vp.X + (vp.Width / 2); yPosition = vp.Y + (vp.Height / 2); device = graphics.GraphicsDevice; base.Initialize(); } protected override void LoadContent() { spriteBatch = new SpriteBatch(GraphicsDevice); cursorTex = Content.Load<Texture2D>("strzalka"); } protected override void UnloadContent() { // TODO: Unload any non ContentManager content here } protected override void Update(GameTime gameTime) { // Allows the game to exit if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed) this.Exit(); base.Update(gameTime); } protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); spriteBatch.Begin(); spriteBatch.Draw(cursorTex, cursorPos, Color.White); spriteBatch.End(); base.Draw(gameTime); } }

• MVC Scaffold Template Not Generating?

  - by monkey9987

  Been working on an MVC project and my templates were not generating. I first created my Model inside my "Models" folder, then did a quick compile. Next I went to the Views folder to get it created, right click and say "Add View" then I clicked the checkbox to create an edit page. What happened was the template would never seem to pull in my Model, it would just have the default header items, but the entire model was missing.  My model was defined as follows: public class LogOnModel { [Required][Display(Name = "User name")]public string UserName;[Required][DataType(DataType.Password)][Display(Name = "Password")]public string Password;[Display(Name = "Remember me?")]public bool RememberMe; } See anything wrong with that? I couldn't figure out why each time I created my View and selected the option to create the "Edit" scaffold automatically, it would come up blank. Turns out I'm missing my get / set methods on the Model class items. Here's my code with the correct setup: public class LogOnModel { [Required][Display(Name = "User name")]public string UserName { get; set; } [Required][DataType(DataType.Password)][Display(Name = "Password")]public string Password { get; set; }[Display(Name = "Remember me?")]public bool RememberMe { get; set; } }  I hope that helps someone out, it's pretty simple when I look at it now, but that's always the case!  ~ Steve

• Prevent Click Fraud in Advertisement system with PHP and Javascript

  - by CodeDevelopr

  I would like to build an Advertising project with PHP, MySQL, and Javascript. I am talking about something like... Google Adsense BuySellAds.com Any other advertising platform My question is mainly, what do I need to look out for to prevent people cheating the system and any other issues I may encounter? My design concept. An Advertisement is a record in the Database, when a page is loaded, using Javascript, it calls my server which in turn will use a PHP script to query the Database and get a random Advertisement. (It may do kore like get an ad based on demographics or other criteria as well) The PHP script will then return the Advertisement to the server/website that is calling it and show it on the page as an Image that will have a special tracking link. I will need to... Count all impressions (when the Advertisement is shown on the page) Count all clicks on the Advertisement link Count all Unique clicks on the Advertisement link My question is purely on the query and displaying of the Advertisement and nothing to do with the administration side. If there is ever money involved with my Advertisement buying/selling of adspace, then the stats need to be accurate and make sure people can't easily cheat the system. Is tracking IP address really the only way to try to prevent click fraud? I am hoping someone with some experience can clarify I am on the right track? As well as give me any advice, tips, or anything else I should know about doing something like this?

• Using Computer Management (MMC) with the Solaris CIFS Service (August 25, 2009)

  - by user12612012

  One of our goals for the Solaris CIFS Service is to provide seamless Windows interoperability: not just to deliver ubiquitous, multi-protocol file sharing, which is obviously a major part of this project, but to support Windows services at a fundamental level.  It's an ongoing mission and our latest update includes support for Windows remote management. Remote management is extremely important to Windows administrators and one of the mainstay tools is Computer Management. Computer Management is a Windows administration application, actually a collection of Microsoft Management Console (MMC) tools, that can be used to configure, monitor and manage local and remote services and resources.  The MMC is an extensible framework of registered components, known as snap-ins, which allows Computer Management to provide comprehensive management features for both the local system and remote systems on the network. Supported Computer Management features include: Share ManagementSupport for share management is relatively complete.  You can create, delete, list and configure shares.  It's not yet possible to change the maximum allowed or number of users properties but other properties, including the Share Permissions, can be managed via the MMC. Users, Groups and ConnectionsYou can view local SMB users and groups, monitor user connections and see the list of open files. If necessary, you can also disconnect users and/or close files. ServicesYou can view the SMF services running on an OpenSolaris system.  This is a read-only view - we don't support service management (the ability to start or stop) SMF services from Computer Management (yet). To ensure that only the appropriate users have access to administrative operations there are some access restrictions on these remote management features. Regular users can: List shares Only members of the Administrators or Power Users groups can: Manage shares List connections Only members of the Administrators group can: List open files and close files Disconnect users View SMF services View the EventLog Here's a screenshot when I was using Computer Management and Server Manager (another Windows remote management application) on Windows XP to view some open files on an OpenSolaris system to prepare a slide presentation on MMC support.

• Data Center Modernization: Harness the power of Oracle Exalogic and Exadata with PeopleSoft

  - by Michelle Kimihira

  Author: Latha Krishnaswamy, Senior Manager, Exalogic Product Management   Allegis Group - a Hanover, MD-based global staffing company is the largest privately held staffing company in the United States with more than 10,000 internal employees and 90,000 contract employees. Allegis Group is a $6+ billion company, offering a full range of specialized staffing and recruiting solutions to clients in a wide range of industries.   The company processes about 133,000 paychecks per week, every week of the year. With 300 offices around the world and the hefty task of managing HR and payroll, the PeopleSoft system at Allegis  is a mission-critical application. The firm is in the midst of a data center modernization initiative. Part of that project meant moving the company's PeopleSoft applications (Financials and HR Modules as well as Custom Time & Expense module) to a converged infrastructure.     The company ran a proof of concept with four different converged architectures before deciding upon Exadata and Exalogic as the platform of choice.   Performance combined with High availability for running mission-critical payroll processes drove this decision.  During the testing on Exadata and Exalogic Allegis applied a particular (11-F) tax update in production environment. What job ran for roughly six hours completed in less than 1.5 hours. With additional tuning the second run of the Tax update 11-F reduced to 33 minutes - a 90% improvement!     Not only that, the move will help the company save money on middleware by consolidating use of Oracle licensing in a single platform.   Summary With a modern data center powered by Exalogic and Exadata to run mission-critical PeopleSoft HR and Financial Applications, Allegis is positioned to manage business growth and improve employee productivity. PeopleSoft applications run on engineered systems platform minimizing hardware and software integration risks.

• Developing games using virtualization on macOS (or Linux) [on hold]

  - by zpinner

  From what I've seen, most of the gamedev tools and engines (that could generate cross platform games) are not supported on Mac. Havok/Project Anarchy, UDK, GameMaker, e.g. . Basically, the only options I found are: Unity3d and monogame + xamarin. Unity is nice and I've been playing with it for some time, but the free version is quite limited when we're talking about shaders, that made me consider that as an indie developer, I might want more freedom to experiment new things, without paying the expensive unity license. I didn't try monogame + xamarin yet, and altough XNA is a very nice game framework, I'd like to have more freedom to experiment and finish a game first before paying for the IDE, which is not possible with the current Xamarin business model. That leaves me with the thought that I must go back to windows, which I'd preferably do it partially, if it's possible. Using BootCamp is something that I'd like to avoid, since it's a pain to reboot when changing OS and that would probably force me to become a 100% windows user. Is there anyone actually developing a game using virtualization solutions like parallels or vmwareFusion? How was your experience?

• Guitar hero clone and music

  - by mm24

  I am an indie game developer and I am doing a game similar to guitar hero. I am using tracks composed by musicians and I contacted them to sing a licensing contract. As is my first indie project I have no idea on how I should deal with the royalties aspect of this because each track as an ISRC code and each time a track is played in public there is a fee to pay to the "local" registration authority. An iPhone game it is downloaded and not played on air (or physically distributed), and hence I think there is a specific legislation for this that specifies how much one should pay. I own some of the tracks composed and for this I think I won't have to pay a royalty (even if the track has an ISRC code) but for other tracks I just have a license "to use". I wonder how a game like Guitar hero can sell on iPhone for as little as 0,99$ and then have "in app purchases" for packs of 3 songs (for about 2 dollars) and make a profit (I imagine they will have to pay a ISRC royalty). Does anyone of you have any idea of this can work or if there is a section in this forum where I can ask this question? I understand is not about coding but I think is about development of a game in the broader sense.

• Configuring BIND to use VM's DNS for specific domain

  - by Srirangan

  I work on a project for which I use an Ubuntu server vm on an Ubuntu host. The VM runs all the services / webapps through haproxy and nginx and serves it on the domain (xyz.com). I manually modify my resolv.conf to use the VMs IP address as the nameserver and I can run my app on the host browser. The problem is I am modifying an auto-generated file (resolv.conf) and I need to do it each time. Is there a smart way to say: -- are you accessing xyz.com? -- if yes use VM's DNS server, else use the hosts

• how to separate a network for traffic

  - by Student_CVO

  At the moment our all computers in one big LAN, it is the intention to separate the admin and edu (it's in a school) especially for traffic and less for security. How do this best? I have a drawing, but can't post it (a can send it in a mail) Firewall?, VLAN?, IPCop (no two green zones)?, pfsense? ... Should there be two scopes on the dhcp server (WIN 2008 R2), one for admin and one for edu or is one scope enough? I would like your advice, I am a student in training with this task as a project.

• Tell Us Once&ndash;Final Phase goes live

  - by BizTalk Visionary

  Yesterday the final phase of ‘Tell Us Once’ went live. This completes the 4 1/2 year journey Solidsoft started on this cross government project with the addition of full electronic distribution of data and the most import piece – access for the citizen to use the service on-line. Tell Us Once (TUO) is the award-winning, cross-government programme that lets people inform central government and local authorities just once of a birth or death. In service in over 95% of councils in England, Scotland and Wales, it provides a permanent solution to the long-standing and frustrating issue of people having to notify the government multiple times. Several years ago, research showed that people had to make up to 44 contacts when reporting a death to government bodies and their local authority. The TUO service is offered as a face-to-face interview by the local authority or by telephone to a dedicated telephony service run by the Department for Work and Pensions (DWP). and a  now a TUO online service for death. From the bereavement section of the  Direct Gov web site the citizen is able to ‘enrich’ the standard death registration data to allow the ‘Tell Us Once’ system inform the various government departments about the death. These include the local council, DVLA, DWP, Passport service and HMRC. For the record this is an excellent example of how an SME working with a large SI partner can deliver success for government in a responsive and agile manner. For me personally it is a proud moment in which a vision I started with a very small team was followed through, extended and finally delivered by an excellent team at Solidsoft.

• Distributed Rendering in the UDK and Unity

  - by N0xus

  At the moment I'm looking at getting a game engine to run in a CAVE environment. So far, during my research I've seen a lot of people being able to get both Unity and the Unreal engine up and running in a CAVE (someone did get CryEngine to work in one, but there is little research data about it). As of yet, I have not cemented my final choice of engine for use in the next stage of my project. I've experience in both, so the learning curve will be gentle on both. And both of the engines offer stereoscopic rendering, either already inbuilt with ReadD (Unreal) or by doing it yourself (Unity). Both can also make use of other input devices as well, such as the kinect or other devices. So again, both engines are still on the table. For the last bit of my preliminary research, I was advised to see if either, or both engines could do distributed rendering. I was advised this, as the final game we make could go into a variety of differently sized CAVEs. The one I have access to is roughly 2.4m x 3m cubed, and have been duly informed that this one is a "baby" compared to others. So, finally onto my question: Can either the Unreal Engine, or Unity Engine make it possible for developers to allow distributed rendering? Either through in built devices, or by creating my own plugin / script?

• Groovy Refactoring in NetBeans

  - by Martin Janicek

  Hi guys, during the NetBeans 7.3 feature development, I spend quite a lot of time trying to get some basic Groovy refactoring to the game. I've implemented find usages and rename refactoring for some basic constructs (class types, fields, properties, variables and methods). It's certainly not perfect and it will definitely need a lot fixes and improvements to get it hundred percent reliable, but I need to start somehow :) I would like to ask all of you to test it as much as possible and file a new tickets to the cases where it doesn't work as expected (e.g. some occurrences which should be in usages isn't there etc.) ..it's really important for me because I don't have real Groovy project and thus I can test only some simple cases. I can promise, that with your help we can make it really useful for the next release. Also please be aware that the current version is focusing only on the .groovy files. That means it won't find any usages from the .java files (and the same applies for finding usages from java files - it won't find any groovy usages). I know it's not ideal, but as I said.. we have to start somehow and it wasn't possible to make it all-in-one, so only other option was to wait for the NetBeans 7.4. I'll focus on better Java-Groovy integration in the next release (not only in refactoring, but also in navigation, code completion etc.) BTW: I've created a new component with surprising name "Refactoring" in our bugzilla[1], so please put the reported issues into this category.

• Alternatives to Pessimistic Locking in Cluster Applications

  - by amphibient

  I am researching alternatives to database-level pessimistic locking to achieve transaction isolation in a cluster of Java applications going against the same database. Synchronizing concurrent access in the application tier is clearly not a solution in the present configuration because the same database transaction can be invoked from multiple JVMs concurrently. Currently, we are subject to occasional race conditions which, due to the optimistic locking we have in place via Hibernate, cause a StaleObjectStateException exception and data loss. I have a moderately large transaction within the scope of my refactoring project. Let's describe it as updating one top-level table row and then making various related inserts and/or updates to several of its child entities. I would like to insure exclusive access to the top-level table row and all of the children to be affected but I would like to stay away from pessimistic locking at the database level for performance reasons mostly. We use Hibernate for ORM. Does it make sense to start a single (perhaps synchronous) message queue application into which this method could be moved to insure synchronized access as opposed to each cluster node using its own, which is a clear race condition hazard? I am mentioning this approach even though I am not confident in it because both the top-level table row and its children could also be updated from other system calls, not just the mentioned transaction. So I am seeking to design a solution where the top-level table row and its children will all somehow be pseudo-locked (exclusive transaction isolation) but at the application and not the database level. I am open to ideas and suggestions, I understand this is not a very cut and dried challenge.

• How should I load level data in java?

  - by Matthew G.

  I'm setting up my engine for a certain action/arcade game to have a set of commands that would look something like this. Set landscape to grass Create rocks at ... Create player at X, Y Set goal to "Get to point X Y" Spawn enemy at X, Y I'd then have each object knowing what it has to do, and acting on its own. I've been thinking about how to store this data. External data files could be parsed by a level class, and certain objects can be spawned through that. I could also create a base level class and extend it for each level, but that'd create a large amount of classes. Another idea is to have one level parser class, but have a case for each level. This would be extremely silly and bulky, but I mention it because I found that I did this at 2 AM last night. I'm finally getting why I have to plan out my inheritances, though. RIP project. I might be completely missing another option.

• Earmarks of a Professional PHP Programmer

  - by Scotty C.

  I'm a 19 year old student who really REALLY enjoys programming, and I'm hoping to glean from your years of experience here. At present, I'm studying PHP every chance I get, and have been for about 3 years, although I've never taken any formal classes. I'd love to some day be a programmer full time, and make a good career of it. My question to you is this: What do you consider to be the earmarks or traits of a professional programmer? Mainly in the field of PHP, but other, more generalized qualifications are also more than welcome, as I think PHP is more of a hobbyist language and may not be the language of choice in the eyes of potential employers. Please correct me if I'm wrong. Above all, I don't want to wast time on something that isn't worth while. I'm currently feeling pretty confident in my knowledge of PHP as a language, and I know that I could build just about anything I need and have it "work", but I feel sorely lacking in design concepts and code structure. I can even write object oriented code, but in my personal opinion, that isn't worth a hill of beans if it isn't organized well. For this reason, I bought Matt Zandstra's book "PHP Objects, Patterns, and Practice" and have been reading that a little every day. Anyway, I'm starting to digress a little here, so back to the original question. What advice would you give to an aspiring programmer who wants to make an impact in this field? Also, on a side note, I've been working on a project with a friend of mine that would give a fairly good idea of where I'm at coding wise. I'm gonna give a link, I don't want anyone to feel as though I'm pushing or spamming here, so don't click it if you don't want to. But if you are interested on giving some feedback there as well, you can see the code on github. I'm known as The Craw there. https://github.com/PureChat/PureChat--Beta-/tree/

• Is it good idea to require to commit only working code?

  - by Astronavigator

  Sometimes I hear people saying something like "All committed code must be working". In some articles people even write descriptions how to create svn or git hooks that compile and test code before commit. In my company we usually create one branch for a feature, and one programmer usually works in this branch. I often (1 per 100, I think and as I think with good reason) do non-compilable commits. It seems to me that requirement of "always compilable/stable" commits conflicts with the idea of frequent commits. A programmer would rather make one commit in a week than test the whole project's stability/compilability ten times a day. For only compilable code I use tags and some selected branches (trunk etc). I see these reasons to commit not fully working or not compilable code: If I develop a new feature, it is hard to make it work writing a few lines of code. If I am editing a feature, it is again sometimes hard to keep code working every time. If I am changing some function's prototype or interface, I would also make hundreds of changes, not mechanical changes, but intellectual. Sometimes one of them could cause me to carry out hundreds of commits (but if I want all commits to be stable I should commit 1 time instead of 100). In all these cases to make stable commits I would make commits containing many-many-many changes and it will be very-very-very hard to find out "What happened in this commit?". Another aspect of this problem is that compiling code gives no guarantee of proper working. So is it good idea to require every commit to be stable/compilable? Does it depends on branching model or CVS? In your company, is it forbidden to make non compilable commits? Is it (and why) a bad idea to use only selected branches (including trunk) and tags for stable versions?

• Proftpd user-auth with mod_sql/mod_sql_passwd

  - by Zae

  I'm reading up how to interface ProFTPd with MySQL for an implementation I'm working on, I noticed it seems like all the example code or instructions I see have the user login field in MySQL set as "varchar(30)". I don't see anything saying there's a limit to the field length for ProFTPd, but I wanted to check around anyway. The project this setup is going to get mixed into was planning to have their universal usernames support "varchar(255)". Can I use that safely? or is there an FTP limitation elsewhere I'm missing?

• An experiment: unlimited free trial

  - by Alex.Davies

  The .NET Demon team have just implemented an experiment that is quite a break from Red Gate's normal business model. Instead of the tool expiring after the trial period, it now continues to work, but with a new message that appears after the tool has saved you a certain amount of time. The rationale is that a user that stops using .NET Demon because the trial expired isn't doing anyone any good. We'd much rather people continue using it forever, as long as everyone that finds it useful and can afford it still pays for it. Hopefully the message appearing is annoying enough to achieve that, but not for people to uninstall it. It's true that many companies have tried it before with mixed results, but we have a secret weapon. The perfect nag message? The neat thing for .NET Demon is that we can easily measure exactly how much time .NET Demon has saved you, in terms of unnecessary project builds that Visual Studio would have done. When you press F5, the message shows you the time saved, and then makes you wait a shorter time before starting your application. Confronted with the truth about how amazing .NET Demon is, who can do anything but buy it? The real secret though, is that while you wait, .NET Demon gives you entertainment, in the form of a picture of a cute kitten. I've only had time to embed one kitten so far, but the eventual aim is for a random different kitten to appear each time. The psychological health benefits of a dose of kittens in the daily life of the developer are obvious. My only concern is that people will complain after paying for .NET Demon that the kittens are gone.
