  • Alternatives for the Snippet Compiler

    - by Marko Apfel
    It seems that the Snippet Compiler is not maintained anymore. So I need an alternative – also for getting syntax highlighting for code in publications. Preferable with the possibility to conserve this highlighting by copying selections to clipboard. Snippet Compiler does not allows this for selections – only by exporting the whole file content to clipboard with HTML- or RTF-formatting (File > Export > HTML to clipboard respectively RTF to clipboard). Today I switched to LINQPad. This application offers constructing LINQ-statements as well as compiling arbitrary code snippets. But there are some other alternatives too: CS-Script - The C# Script Engine CS-Script is a CLR (Common Language Runtime) based scripting system which uses ECMA-compliant C# as a programming language. CS-Script currently targets Microsoft implementation of CLR (.NET 2.0/3.0/3.5. sharpsnippetcompiler C# Snippet Compiler is a tiny IDE to create, debug and run your C# programs CsharpRepl C# interactive shell that is part of Mono's C# compiler. An interactive shell is usually referred to as a read eval print loop or repl. The C# interactive shell is built on top of the Mono.CSharp library, a library that provides a C# compiler service that can be used to evaluate expressions and statements on the flight. What I miss is an alternative with syntax highlighting like in my Visual Studio: Instead of:

  • Is knowledge of hacking mechanisms required for an MMO?

    - by Gabe
    Say I was planning on, in the future (not now! There is alot I need to learn first) looking to participating in a group project that was going to make a massively multiplayer online game (mmo), and my job would be the networking portion. I'm not that familiar with network programming (I've read a very basic book on PHP, MYSQL and I messed around a bit with WAMP). In the course of my studying of PHP and MYSQL, should I look into hacking? Hacking as in port scanning, router hacking, etc. In MMOs people are always trying to cheat, bots and such, but the worst scenario would be having someone hack the databases. This is just my conception of this, I really don't know. I do however understand networking fairly well, like subnetting/ports/IP's (local/global)/etc. In your professional opinion, (If you understand the topic, enlighten me) Should I learn about these things in order to counter the possibility of this happening? Also, out of the things I mentioned (port scanning, router hacking) Is there anything else that pertains to hacking that I should look into? I'm not too familiar with the malicious/Security aspects of Networking. And a note: I'm not some kid trying to learn how to hack. I just want to learn as much as possible before I go to college, and I really need to know if I need to study this or not.

  • [Dear Recruiter] I developed in Mo'Fusion

    - by refuctored
    Forward: Sometimes I really feel like technology recruiters have no experience or knowledge of the field they are recruting for.  A warning to those companies hiring technical recruiters -- ensure that the technical recruiters you hire to fill a position are actually technical.  Here's proof below, where I make up completely ridiculous technologies, but still have interest from the recruiter for an interview. Letter to me: Hello - Your name came up as a possible match for a long term contract Cold Fusion Developer role I have in Bothell, WA.  This role requires you to be onsite in Bothell, WA. This is  a tough role to fill so I was hoping you might have someone you can recommend? Unfortunately no telecommute. Thank you! Sincerly, Mindy Recruiter My response: Mindy -- Wow I'm super-excited that you took the time to contact me about this position!  Let me tell you, you won't be disappointed with my skill set! Firstly, I've been developing in ColdFusion since 1993 before it was owned by Adobe and it was operating under code name, "Hot-Jack".  Recently I started developing under the Domain-View-Driven-Domain-Model (DVDDM), integrating client-side CF on Moobuntu.  Not only do I have a boat load of ColdFusion EXP,  I also have a ton of experience in the open source communities lesser known derivative of CF, Mo'Fusion (MF).  I've also invested thousands of hours of my time learning esoteric programming languages. Look forward to working with you! George And her response: Hi George – just left you a message. Give me a call at your convenience.  The role does require someone to be onsite here.. are you able to relocate yourself? Mindy [Sigh]

  • About to smash my keyboard!! Ubuntu 13.1 issues with AMD driver & Audio

    - by DNex
    Let me preface with saying that this is my 2nd day on Linux. I really want to make it work but these issues are driving me up the wall! I've done exhaustive google searches but have not been able to figure anything out. I am on Ubuntu 13.10, my graphics card is AMD Radeon HD4200. My sound card is a realtek HDMI. I've tried downloading and installing both drivers but nothing works. Graphics card: When I run the .run file (from http://www2.ati.com/drivers/legacy/amd-driver-installer-catalyst-13.1-legacy-linux-x86.x86_64.zip) I get an error. I check the fglrx-install log and it says this: Check if system has the tools required for installation. fglrx installation requires that the system have kernel headers. /lib/modules/3.11.0-12-generic/build/include/linux/version.h cannot be found on this system. One or more tools required for installation cannot be found on the system. Install the required tools before installing the fglrx driver. Optionally, run the installer with --force option to install without the tools. Forcing install will disable AMD hardware acceleration and may make your system unstable. Not recommended. Audio: Since my first install I've had no audio. I've tried everything outlined in this site: http://itsfoss.com/fix-sound-ubuntu-1304-quick-tip/ to no avail. I've download the linux drivers from Realtek HDMI audio but have had no luck. Any help would be extremely appreciated.

  • Junior developer introduction to job industry

    - by lady_killer
    I am a junior developer at my second working experience, the first one using PHP with WordPress and currently on Groovy on Grails. I like coding, I attend meetup to discuss technology etc but I still did not understand how to become a real professional with the "know how" attitude. I read Clean Coder, the author advises to spend 20 hours per week of my spare time to learn new technologies and to keep myself up to date. I do not find this realistic, if you want to have a bit of a social life, and I also noticed that learning at work, at least in the places where I worked, is not ideal. No support from seniors for new projects, no pair programming and code reviews, no company trainings, one hour a week tech meetings where seniors walk away after a bit because they already know the topic discussed and so on. Sometimes is quite hard to keep the motivation... My questions are: Is our industry supposed to be like this? Is there real team working in the sense of sharing knowledge and help juniors to get up to speed? Are we supposed to learn new technologies or technology features just in our spare time?Clean Coder says football players do not train during official matches and our working hours are like official matches, we should just perform and learn in other moments. Is it really like this? How can I improve my skills with no support? Is it enough to read books and try out the exercises and perhaps some katas? In almost 5 month of Groovy on Grails experience at work, I have never had the opportunity to create anything from scratch, just worked on existing issues where it was even really difficult to get the domain knowledge from senior devs.

  • Ubuntu 11.10 won't boot on Dell XPS 8300

    - by Phil Gorman
    I have a brand new Dell Studio XPS 8300 desktop with 17-2600 cpu, H67 chipset, 8GB DDR3, 2 1TB HDDs in mirrored RAID, and AMD Radeon 6770. Dell doesn't support Ubuntu here in Australia so it came with Windows 7 and Windows software. Yes I had to pay for an O.S. and software I didn't want to get hardware I did want, all at a greatly inflated price. It's not all beer and skittles in the land of Oz. I changed boot priorities in the BIOS to DVD and ran Ubuntu 11.10 64bit from the ISO with NOMODESET. The installation reformatted all partitions to rid me of the dreaded Windows. All was well until until reboot. The BIOS does its thing, then its "The Black Screen of Death" with a blinking cursor; no boot screen, no Grub, no keyboard, no mouse. I've searched Dell and Ubuntu forums in vain. Can you help? I would be really grateful for any advice which can help turn my big expensive paperweight into a really useful machine. Thank you in anticipation kind people. Phil

  • Moving my sprite in XNA using classes

    - by Tom
    Hey, im a newbie at this programming lark and its really frustrating me. I'm trying to move a snake in all directions while using classes. Ive created a vector2 for speed and ive attempted creating a method which moves the snake within the snake class. Now I'm confused and not sure what to do next. Appreciate any help. Thanks :D This is what i've done in terms of the method... public Vector2 direction() { Vector2 inputDirection = Vector2.Zero; if (Keyboard.GetState().IsKeyDown(Keys.Left)) inputDirection.X -= -1; if (Keyboard.GetState().IsKeyDown(Keys.Right)) inputDirection.X += 1; if (Keyboard.GetState().IsKeyDown(Keys.Up)) inputDirection.Y -= -1; if (Keyboard.GetState().IsKeyDown(Keys.Down)) inputDirection.Y += 1; return inputDirection * snakeSpeed; } Appreciate any help. Thanks :D EDIT: Well let me make everything clear. Im making a small basic game for an assignment. The game is similar to the old snake game on the old Nokia phones. I've created a snake class (even though I'm not sure whether this is needed because im only going to be having one moving sprite within the game). After I written the code above (in the snake class), the game ran with no errors but I couldn't actually move the image :( EDIT2: Thanks so much for everyones responses!!

  • PublishingWeb.ExcludeFromNavigation Missing

    - by Michael Van Cleave
    So recently I have had to make the transition from the SharePoint 2007 codebase to SharePoint 2010 codebase. Needless to say there hasn't been much difficulty in the changeover. However in a set of code that I was playing around with and transitioning I did find one change that might cause some pain to others out there that have been programming against the PublishingWeb object in the Microsoft.SharePoint.Publishing namespace. The 2007 snippet of code that work just fine in 2007 looks like: using (SPSite site = new SPSite(url)) using (SPWeb web = site.OpenWeb()) {      PublishingWeb publishingWeb = PublishingWeb.GetPublishingWeb(web);     publishingWeb.ExcludeFromNavigation(true, itemID);     publishingWeb.Update(); } The 2010 update to the code looks like: using (SPSite site = new SPSite(url)) using (SPWeb web = site.OpenWeb()) {     PublishingWeb publishingWeb = PublishingWeb.GetPublishingWeb(web);     publishingWeb.Navigation.ExcludeFromNavigation(true, itemID); //--Had to reference the Navigation object.     publishingWeb.Update(); } The purpose of the code is to keep a page from showing up on the global or current navigation when it is added to the pages library. However you see that the update to the 2010 codebase actually makes more "object" sense. It specifies that you are technically affecting the Navigation of the Publishing Web, instead of the Publishing Web itself. I know that this isn't a difficult problem to fix, but I thought it would be something quick to help out the general public. Michael

  • 12.04 No Sound - ALC888 / Radeon 3200HD

    - by Ross
    Evening all. I have a MSI U230 netbook, MV40 processor, 4Gb RAM with integrated ATI Radeon 3200HD grahics & an ALC888 codec integrated soundcard. It has HDMI out as well. I've tried a few distro's and have been around linux for a short time. I reckon I've settled on Ubuntu 12.04 (32bit) due to it doing pretty much everything I want it to. I'm working with a fresh install right now. I recently re-installed when I was going in circles trying to solve my problem before. I install Ubuntu and it works, except for the sound. I have tried things like reinstalling Alsa, editing my asound.conf file, installing HDA Verb and a few other things. Its at the point where I need to ask for help... Some outputs: ross@ross:~$ aplay -l ** List of PLAYBACK Hardware Devices ** card 0: SB [HDA ATI SB], device 0: ALC888 Analog [ALC888 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 ross@ross:~$ uname -r 3.2.0-34-generic-pae ross@ross:~$ lspci | grep VGA 01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RS780M/RS780MN [Mobility Radeon HD 3200 Graphics] ross@ross:~$ lspci | grep Audio 00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) 01:05.1 Audio device: Advanced Micro Devices [AMD] nee ATI RS780 HDMI Audio [Radeon HD 3000-3300 Series] Added options snd-hda-intel position_fix=1 to alsa-base.conf file Unmuted all in alsamixer Can anyone suggest anything more?

  • cygwin GNU make .net program piping inconsistent behavior

    - by Codism
    This question may sound like a superuser question but I feel there is something related to programming. Anyway, my computer had a fresh installation of Win 7 64 and cygwin recently. Now I observed some problem with pipe handling in gnu make file. The following is the Makefile I use to reproduce the issue: all: fsutil | cat my-dotnet-console.exe | cat The problem is: for the first command line, the piping works every time but for the second command line, the piping barely works - I got no result for the second command for most cases, regardless of the environment (cmd or bash) in which the make file is invoked. However, if I copy paste the second command line into cmd (or bash), the pipe works every time. The following is my .net program: static void Main(string[] args) { Console.WriteLine(new string('a', 40)); Console.Out.Flush(); } The make version is 3.82.90 but the same problem was observed in a previous version (because of the windows path handling problem in 3.82.9, I replaced make.exe with a previous version). I don't know the exact cygwin version I have installed but the current version on cygwin.com is 1.7.11-1. Currently, my work around is to redirect the output to a temporary file but it would be great if I can avoid the temporary file. Thanks

  • Distinction between API and frontend-backend

    - by Jason
    I'm trying to write a "standard" business web site. By "standard", I mean this site runs the usual HTML5, CSS and Javascript for the front-end, a back-end (to process stuff), and runs MySQL for the database. It's a basic CRUD site: the front-end just makes pretty whatever the database has in store; the backend writes to the database whatever the user enters and does some processing. Just like most sites out there. In creating my Github repositories to begin coding, I've realized I don't understand the distinction between the front-end back-end, and the API. Another way of phrasing my question is: where does the API come into this picture? I'm going to list some more details and then questions I have - hopefully this gives you guys a better idea of what my actual question is, because I'm so confused that I don't know the specific question to ask. Some more details: I'd like to try the Model-View-Controller pattern. I don't know if this changes the question/answer. The API will be RESTful I'd like my back-end to use my own API instead of allowing the back-end to cheat and call special queries. I think this style is more consistent. My questions: Does the front-end call the back-end which calls the API? Or does the front-end just call the API instead of calling the back-end? Does the back-end just execute an API and the API returns control to the back-end (where the back-end acts as the ultimate controller, delegating tasks)? Long and detailed answers explaining the role of the API alongside the front-end back-end are encouraged. If the answer depends on the model of programming (models other than the Model-View-Controller pattern), please describe these other ways of thinking of the API. Thanks. I'm very confused.

  • Building a Redundant / Distrubuted Application

    - by MattW
    This is more of a "point me in the right direction" question. I (and my team of 3) have built a hosted web app that queues and routes customer chat requests to available customer service agents (It does other things as well, but this is enough background to illustrate the issue). The basic dev architecture today is: a single page ajax web UI (ASP.NET MVC) with floating chat windows (think Gmail) a backend Windows service to queue and route the chat requests this service also logs the chats, calculates service levels, etc a Comet server product that routes data between the web frontend and the backend Windows service this also helps us detect which Agents are still connected (online) And our hardware architecture today is: 2 servers to host the web UI portion of the application a load balancer to route requests to the 2 different web app servers a third server to host the SQL Server DB and the backend Windows service responsible for queuing / delivering chats So as it stands today, one of the web app servers could go down and we would be ok. However, if something would happen to the SQL Server / Windows Service server we would be boned. My question - how can I make this backend Windows service logic be able to be spread across multiple machines (distributed)? The Windows service is written to accept requests from the Comet server, check for available Agents, and route the chat to those agents. How can I make this more distributed? How can I make it so that I can distribute the work of the backend Windows service can be spread across multiple machines for redundancy and uptime purposes? Will I need to re-write it with distributed computing in mind? I should also note that I am hosting all of this on Rackspace Cloud instances - so maybe it is something I should be less concerned about? Thanks in advance for any help!

  • Unable to install Ubuntu 12.04.1 on Virtualbox on Windows 7 Host

    - by arcube
    I would like to install Ubuntu 12.04.1 in a virtual box on windows 7 host however I get a black screen after selecting to install Ubuntu i.e. right after choosing English language I have tried the 32bit and 64bit version desktop version, have also read thru some guides e.g. http://www.psychocats.net/ubuntu/virtualbox but I could not find any solution to fix this problem. BTW I have Ubuntu installed using Virtual PC (not running at the same time), also I have mac OS (mountain lion) installed using Virtual Box so I do not think it is a problem with the virtual box or windows 7 host. My VM configuration is with 1 core and 1 GB of ram using 20GB VDI; rest is default config. My hardware is Core i7 3770k / Asus P8Z77-V Deluxe / GSkill 32GB which I believe should be more than sufficient to run another VM. I have moved my user profile from SSD to HDD via junction however IMHO it should not matter. Has anyone else come across this problem and found a solution? Any help/thoughts on how to solve this would be very much appreciated.

  • Observable Adapter

    - by Roman Schindlauer
    .NET 4.0 introduced a pair of interfaces, IObservable<T> and IObserver<T>, supporting subscriptions to and notifications for push-based sequences. In combination with Reactive Extensions (Rx), these interfaces provide a convenient and uniform way of describing event sources and sinks in .NET. The StreamInsight CTP refresh in November 2009 included an Observable adapter supporting “reactive” event inputs and outputs.   While we continue to believe it enables an important programming model, the Observable adapter was not included in the final (RTM) release of Microsoft StreamInsight 1.0. The release takes a dependency on .NET 3.5 but for timing reasons could not take a dependency on .NET 4.0. Shipping a separate copy of the observable interfaces in StreamInsight – as we did in the CTP refresh – was not a viable option in the RTM release.   Within the next months, we will be shipping another preview of the Observable adapter that targets .NET 4.0. We look forward to gathering your feedback on the new adapter design! We plan to include the Observable adapter implementation into the product in a future release of Microsoft StreamInsight.

  • Is there any evidence that drugs can actually help programmers produce "better" code? [closed]

    - by sytycs
    I just read this quote from Steve Jobs: "Doing LSD was one of the two or three most important things I have done in my life." Also a quote from that article: He was hardly alone among computer scientists in his appreciation of hallucinogenics and their capacity to liberate human thought from the prison of the mind. Now I'm wondering if there's any evidence to support the theory that drugs can help make a "better" programmer. Has there ever been a study where programmers have been given drugs to see if they could produce "better" code? Is there a well-known programming concept or piece of code which originated from people who were on drugs? EDIT So I did a little more research and it turns out Dennis R. Wier actually documented how he took LSD to wrap his head around a coding project: "At one point in the project I could not get an overall viewpoint for the operation of the entire system. It really was too much for my brain to keep all the subtle aspects and processing nuances clear so I could get a processing and design overview. After struggling with this problem for a few weeks, I decided to use a little acid to see if it would enable a breakthrough, because otherwise, I would not be able to complete the project and be certain of a consistent overall design"[1] There is also an interesting article on wired about Kevin Herbet, who used LSD to solve tough technical problems and chemist Kary Mullis even said "...that LSD had helped him develop the polymerase chain reaction that helps amplify specific DNA sequences."

  • Introducing Deep Fried Devcast

    - by Matt Christian
    I've been working on a new podcast for the game development community called the Deep Fried Devcast.  Currently we are in pre-production but should have some episodes up in the near future.  Here is a quick FAQ about the show: What is the Deep Fried Devcast? The Deep Fried Devcast is a bi-weekly show all about game development.  The show will feature developer interviews, a focus on the technical aspects of game development (programming, technical design), the business of team game development (time management, project management), and other areas focused around the actual development of games. Wait, no game design?  No game discussions?! Calm down, calm down.  Although the focus of the podcast is on the technical aspects of game dev, there will be episodes and content focused on all areas of the gaming industry, including discussion on design, story, recent game releases, games we've been playing, etc...  Anything could show up in the Deep Fried Devcast and nothing is off limits. How can I help? We're always looking for new content ideas, emails, and anything you want to send us (within some kind of reason!).  You can even be a guest host if you want!  Email us at: deepfrieddevcast [AT] gmail [DOT] com Where's the podcast?! We're still recording it!  Don't worry, it will be up soon.  Keep an eye on www.deepfrieddevcast.com for the latest updates (that will be up soon too!).

  • Examples of limitations in IT due to different bit length by design

    - by Alaudo
    I am teaching the course "Introduction in Programming" for the first-year students and would like to find interesting examples where the datatype size in bits, chosen by design, led to certain known restrictions or important values. Here are some examples: Due to the fact that the Bell teleprinter used 7-bit-code (later accepted as ASCII) until now have we often to encode attachments in electronic messages to contain only 7 bit data. Classical limitation of 32-bit address space leads to the 4Gb maximal RAM size available for 32-bit systems and 4Gb maximal file size in FAT32. Do you know some other interesting examples how the choice of the data type (and especially its binary length) influenced the modern IT world. Added after some discussion in comments: I am not going to teach how to overcome limitations. I just want them to know that 1 byte can hold the values from -127..0..+127 o 0..255, 2 bytes cover the range 0..65535 etc by proving examples they know from other sources, like the above-mentioned base64 encoding etc. We are just learning the basic datatypes and I am trying to find a good reference for "how large" these types are.

  • DVDs and CDs not recognized

    - by Larry Doyle
    I have Ubuntu 12.04 LTS installed on my computer (Sony Vaio VGN-NS205N). It reads some CDs and DVDs just fine, but many others it will not recognize at all, or will only recognize after opening and closing the CD tray many times. It just shows the cd/dvd drive as being empty and won't show that anything is on there at all. I have a few DVDs (from the same publisher) that work every time. This comes up most often when trying to show my kid Bob the Builder, etc. Some data CDs I would like to work with also have the same issue. It's not a hardware or defective disc problem, since all these will play in Windows on the same machine. It's just really annoying to have to switch operating systems to play videos or get data off discs. All the searches I have done people recommend installing medibuntu and other repositories. I have and they are all up to date. No change. Any help that works would be greatly appreciated.

  • My Windows 8 App in Windows Store

    - by Stephen.Walther
    Finally, you have a good reason to upgrade to Windows 8! My Brain Eaters app was just accepted into the Windows Store. Just in time for Halloween! The Brain Eaters app is a sample app from my soon to be released book Windows 8 Apps with HTML5 and JavaScript. The game illustrates several important programming concepts which you need when building Windows 8 games with JavaScript such as using HTML5 Canvas and the new requestAnimationFrame() method. If you are looking for Halo or Call of Duty then you will be disappointed. If you are looking for PAC-MAN then you will be disappointed. I created the simplest arcade game that I could imagine so I could explain it in the book. All of the code for the game is included with the book. The goal of the game is to eat the food pellets while avoiding the zombies while running around a maze. Every time you get eaten by a zombie, you can hear my six year old son saying “Oh No!”. Here’s the link to the game: http://apps.microsoft.com/webpdp/app/brain-eaters/e283c8d0-1fed-4b26-a8bf-464584c9de6d

  • Hallmarks 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 hallmarks 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/

  • Why do programmers write applications and then make them free?

    - by Ken
    As an entrepreneur/programmer who makes a good living from writing and selling software, I'm dumbfounded as to why developers write applications and then put them up on the Internet for free. You've found yourself in one of the most lucrative fields in the world. A business with 99% profit margin, where you have no physical product but can name your price; a business where you can ship a buggy product and the customer will still buy it. Occasionally some of our software will get a free competitor, and I think, this guy is crazy. He could be making a good living off of this but instead chose to make it free. Do you not like giant piles of money? Are you not confident that people would pay for it? Are you afraid of having to support it? It's bad for the business of programming because now customers expect to be able to find a free solution to every problem. (I see tweets like "is there any good FREE software for XYZ? or do I need to pay $20 for that".) It's also bad for customers because the free solutions eventually break (because of a new OS or what have you) and since it's free, the developer has no reason to fix it. Customers end up with free but stale software that no longer works and never gets updated. Customer cries. Developer still working day job cries in their cubical. What gives? PS: I'm not looking to start an open-source/software should be free kind of debate. I'm talking about when developers make a closed source application and make it free.
