• Using model tools as map editor

  - by cooky451

  I want to make a game which would require a 3D map editor. Of course, I would like to avoid creating such an editor. My idea is now to use modeling tools (3DS Max, Maya, Blender) to create the map, and to give game specific objects specified names. This way I'd just need to write an COLLADA - native map format converter. But I'm not sure if this is possible the way I imagine it, that's why I'd like to hear your thoughts on the matter. Are modeling tools suitable to create big open world maps? Can this "naming convention"-idea for game specific objects work? Are the modeling tools able to export a scene in chunks / in a way that occlusion culling and collision detection can be properly done? If not: Is there a way to build a suitable data structure from the exported data?

• Design Code Outside of an IDE (C#)?

  - by ryanzec

  Does anyone design code outside of an IDE? I think that code design is great and all but the only place I find myself actually design code (besides in my head) is in the IDE itself. I generally think about it a little before hand but when I go to type it out, it is always in the IDE; no UML or anything like that. Now I think having UML of your code is really good because you are able to see a lot more of the code on one screen however the issue I have is that once I type it in UML, I then have to type the actual code and that is just a big duplicate for me. For those who work with C# and design code outside of Visual Studio (or at least outside Visual Studio's text editor), what tools do you use? Do those tools allow you to convert your design to actual skeleton code? It is also possible to convert code to the design (when you update the code and need an updated UML diagram or whatnot)?

• Should I reorder partitions regarding performance

  - by Marcel

  I have in principal 3 big partitions on my Netbook. One Windows, one for shared files, one for Ubuntu. I recently find out (using hdparm) the the hardisk seems to have much better perfomance on the first 2/3 (~ 60MB/s) than on the last 1/3 (~ 40MB/s). I am thinking to delete the second partition and create new partitions for "swap" and / directly after Windows. Does this effort make sense? I also wanna upgrade to 10.4/10.10 but keep the option to go back to the old system, so maybe I install ubuntu completely in a/this new partition?

• Installed Ubuntu in VMware Player, Black side bars / broken GUI

  - by Eric

  I recently installed Ubuntu 12.10 in VMware Player and have came up with a black sidebar, missing icons, a pretty broken GUI. Everything works just fine though. I am able to run Firefox and open termainal and all that good stuff just fine, it's just that I can SEE them on the sidebar. I have to open up a seperate window on Windows with a picture of the Ubuntu 12.10 desktop in order for me to know what to click on, but once I do click on it, it's pretty much smooth sailing from there(not counting closing Firefox and several other things). Again, everything works just fine, but when it comes to the sidebar, the GUI, the dashboard (get a completely black screen for when I open dash board), they come up as completely black, broken (visual tears and what not), and hoving over them just brings up a big black bar (assuming it's the "zooming" in of the icon, but it just shows a black bar of where the icon should be). I'm not exactly sure what so do to get this to work (to fix the GUI), any ideas as to what I may do to fix this?

• genetic algorithm for leveling/build test

  - by Renan Malke Stigliani

  I'm starting o build a online PVP (duel like, one-to-one) game, where there is leveling, skill points, special attacks and all the common stuff. Since I never did anything like that, I'm still thinking about the maths behind the level/skill/special balances. So I thought good way of testing the best/combo builds would implement a Genetic Algorith. It'd be like that: Generate a big portion of random characters Make them fight, level them up accordingly to the victories(more XP)/losses(less XP) Mate the winners, crossing their builds, to try to make even best characters Add some more random chars, emulating new players Repeat the process for some time, or util find some chars who can beat everyone butts So I could play with the math and try to find the balance where the top x% chars would be a mix of various build types. So, is it a good idea, or there are some other easier method to do the balance? PS: I like this also, because it sounds funny

• Is it possible to use RubyGnome2's/QtRuby's HTML renderers to make UI for a Ruby script?

  - by mjr

  I'd like to make a graphical user interface for my script, instead of running it from the console. I'm aware there's a wealth of UI libraries for Ruby, but I'm quite familiar with HTML and CSS and I'd like to use them for building an interface. So the question is: Is it possible to use a HTML rendering library to make such an UI? From what I understand, it's relatively easy to put in a HTML rendered view of something, but is it possible to communicate back with the script? Like when I push that big red button, it actually tells the script to act on it? Obviously it's possible if the script run on the server side, but I'd like to run it as a desktop application.

• IBM "per core" comparisons for SPECjEnterprise2010

  - by jhenning

  I recently stumbled upon a blog entry from Roman Kharkovski (an IBM employee) comparing some SPECjEnterprise2010 results for IBM vs. Oracle. Mr. Kharkovski's blog claims that SPARC delivers half the transactions per core vs. POWER7. Prior to any argument, I should say that my predisposition is to like Mr. Kharkovski, because he says that his blog is intended to be factual; that the intent is to try to avoid marketing hype and FUD tactic; and mostly because he features a picture of himself wearing a bike helmet (me too). Therefore, in a spirit of technical argument, rather than FUD fight, there are a few areas in his comparison that should be discussed. Scaling is not free For any benchmark, if a small system scores 13k using quantity R1 of some resource, and a big system scores 57k using quantity R2 of that resource, then, sure, it's tempting to divide: is  13k/R1 > 57k/R2 ? It is tempting, but not necessarily educational. The problem is that scaling is not free. Building big systems is harder than building small systems. Scoring  13k/R1  on a little system provides no guarantee whatsoever that one can sustain that ratio when attempting to handle more than 4 times as many users. Choosing the denominator radically changes the picture When ratios are used, one can vastly manipulate appearances by the choice of denominator. In this case, lots of choices are available for the resource to be compared (R1 and R2 above). IBM chooses to put cores in the denominator. Mr. Kharkovski provides some reasons for that choice in his blog entry. And yet, it should be noted that the very concept of a core is: arbitrary: not necessarily comparable across vendors; fluid: modern chips shift chip resources in response to load; and invisible: unless you have a microscope, you can't see it. By contrast, one can actually see processor chips with the naked eye, and they are a bit easier to count. If we put chips in the denominator instead of cores, we get: 13161.07 EjOPS / 4 chips = 3290 EjOPS per chip for IBM vs 57422.17 EjOPS / 16 chips = 3588 EjOPS per chip for Oracle The choice of denominator makes all the difference in the appearance. Speaking for myself, dividing by chips just seems to make more sense, because: I can see chips and count them; and I can accurately compare the number of chips in my system to the count in some other vendor's system; and Tthe probability of being able to continue to accurately count them over the next 10 years of microprocessor development seems higher than the probability of being able to accurately and comparably count "cores". SPEC Fair use requirements Speaking as an individual, not speaking for SPEC and not speaking for my employer, I wonder whether Mr. Kharkovski's blog article, taken as a whole, meets the requirements of the SPEC Fair Use rule www.spec.org/fairuse.html section I.D.2. For example, Mr. Kharkovski's footnote (1) begins Results from http://www.spec.org as of 04/04/2013 Oracle SUN SPARC T5-8 449 EjOPS/core SPECjEnterprise2010 (Oracle's WLS best SPECjEnterprise2010 EjOPS/core result on SPARC). IBM Power730 823 EjOPS/core (World Record SPECjEnterprise2010 EJOPS/core result) The questionable tactic, from a Fair Use point of view, is that there is no such metric at the designated location. At www.spec.org, You can find the SPEC metric 57422.17 SPECjEnterprise2010 EjOPS for Oracle and You can also find the SPEC metric 13161.07 SPECjEnterprise2010 EjOPS for IBM. Despite the implication of the footnote, you will not find any mention of 449 nor anything that says 823. SPEC says that you can, under its fair use rule, derive your own values; but it emphasizes: "The context must not give the appearance that SPEC has created or endorsed the derived value." Substantiation and transparency Although SPEC disclaims responsibility for non-SPEC information (section I.E), it says that non-SPEC data and methods should be accurate, should be explained, should be substantiated. Unfortunately, it is difficult or impossible for the reader to independently verify the pricing: Were like units compared to like (e.g. list price to list price)? Were all components (hw, sw, support) included? Were all fees included? Note that when tpc.org shows IBM pricing, there are often items such as "PROCESSOR ACTIVATION" and "MEMORY ACTIVATION". Without the transparency of a detailed breakdown, the pricing claims are questionable. T5 claim for "Fastest Processor" Mr. Kharkovski several times questions Oracle's claim for fastest processor, writing You see, when you publish industry benchmarks, people may actually compare your results to other vendor's results. Well, as we performance people always say, "it depends". If you believe in performance-per-core as the primary way of looking at the world, then yes, the POWER7+ is impressive, spending its chip resources to support up to 32 threads (8 cores x 4 threads). Or, it just might be useful to consider performance-per-chip. Each SPARC T5 chip allows 128 hardware threads to be simultaneously executing (16 cores x 8 threads). The Industry Standard Benchmark that focuses specifically on processor chip performance is SPEC CPU2006. For this very well known and popular benchmark, SPARC T5: provides better performance than both POWER7 and POWER7+, for 1 chip vs. 1 chip, for 8 chip vs. 8 chip, for integer (SPECint_rate2006) and floating point (SPECfp_rate2006), for Peak tuning and for Base tuning. For example, at the 8-chip level, integer throughput (SPECint_rate2006) is: 3750 for SPARC 2170 for POWER7+. You can find the details at the March 2013 BestPerf CPU2006 page SPEC is a trademark of the Standard Performance Evaluation Corporation, www.spec.org. The two specific results quoted for SPECjEnterprise2010 are posted at the URLs linked from the discussion. Results for SPEC CPU2006 were verified at spec.org 1 July 2013, and can be rechecked here.

• SQLAuthority News – 7th Anniversary of Blog – A Personal Note

  - by Pinal Dave

  Special Day Today is a very special day – seven years ago I blogged for the very first time.  Seven years ago, I didn’t know what I was doing, I didn’t know how to blog, or even what a blog was or what to write.  I was working as a DBA, and I was trying to solve a problem – at my job, there were a few issues I had to fix again and again and again.  There were days when I was rewriting the same solution over and over, and there were times when I would get very frustrated because I could not write the same elegant solution that I had written before.  I came up with a solution to this problem – posting these solutions online, where I could access them whenever I needed them.  At that point, I had no idea what a blog was, or even how the internet worked, I had no idea that a blog would be visible to others.  Can you believe it? Google it on Yahoo! After a few posts on this “blog,” there was a surprise for me – an e-mail saying that someone had left me a comment.  I was surprised, because I didn’t even know you could comment on a blog!  I logged on and read my comment.  It said: “I like your script,but there is a small bug.  If you could fix it, it will run on multiple other versions of SQL Server.”  I was like, “wow, someone figured out how to find my blog, and they figured out how to fix my script!”  I found the bug, I fixed the script, and a wrote a thank you note to the guy.  My first question for him was: how did you figure it out – not the script, but how to find my blog?  He said he found it from Yahoo Search (this was in the time before Google, believe it or not). From that day, my life changed.  I wrote a few more posts, I got a few more comments, and I started to watch my traffic.  People were reading, commenting, and giving feedback.  At the end of the day, people enjoyed what I was writing.  This was a fantastic feeling!  I never thought I would be writing for others.  Even today, I don’t feel like I am writing for others, but that I am simply posting what I am learning every day.  From that very first day, I decided that I would not change my intent or my blog’s purpose. 72 Million Views – 2600 Posts – 57000 comments – 10 books – 9 courses Today, this blog is my habit, my addiction, my baby.  Every day I try to learn something new, and that lesson gets posted on the blog.  Lately there have been days where I am traveling for a full 24 hours, but even on those days I try to learn something new, and later when I have free time, I will still post it to the blog.  Because of this habit, this blog has over 72 millions views, I have written more than 2600 posts, and there are 57,000 comments and counting.  I have also written 10 books, 9 courses, and learned so many things.  This blog has given me back so much more than I ever put it into it.  It gave me an education, a reason to learn something new every day, and a way to connect to people.  I like to think of it as a learning chain, a relay where we all pass knowledge from one to another. Never Ending Journey When I started the blog, I thought I would write for a few days and stop, but now after seven years I haven’t stopped and I have no intention of stopping!  However, change happens, and for this blog it will start today.  This blog started as a single resource for SQL Server, but now it has grown beyond, to Sharepoint, Personal Development, Developer Training, MySQL, Big Data, and lots of other things.  Truly speaking, this blog is more than just SQL Server, and that was always my intention.  I named it “SQL Authority,” not “SQL Server Authority”!  Loudly and clearly, I would like to announce that I am going to go back to my roots and start writing more about SQL, more about big data, and more about the other technology like relational databases, MySQL, Oracle, and others.  My goal is not to become a comprehensive resource for every technology, my goal is to learn something new every day – and now it can be so much more than just SQL Server.  I will learn it, and post it here for you. I have written a very long post on this anniversary, but here is the summary: Thank You.  You all have been wonderful.  Seven years is a long journey, and it makes me emotional.  I have been “with” this blog before I met my wife, before we had our daughter.  This blog is like a fourth member of the family.  Keep reading, keep commenting, keep supporting.  Thank you all.

• How could this diagram of the current most lucrative technologies be improved?

  - by Edward Tanguay

  I'm giving a talk in April 2011 on the "Developer English" and showing my non-developer audience, mostly English teachers, various diagrams to explain how developers see their industry etc. One of these diagrams is "Hot Technologies", basically, if you want to become a developer, what technologies should you learn to have the highest chance of (1) getting a job (2) making a good salary, and (3) work with the most exciting technology. This is a draft I made just to get some ideas out, basically C#, PHP, Java are where the bulk of the jobs are. Mobile development has a big future. JavaScript is becoming more and more important, and I want to list "minor technologies" such a Python, Ruby on Rails to the side, I assume e.g. that in general, there are a much smaller percentage of jobs in these technologies as in C#, PHP, Java. How could this diagram be improved?

• Moving Forward with Code Iteration

  - by rcapote

  There are times when working on my programming projects, and I get to a point where I'm ready to move on to the next part of my program. However, when I sit down to implement this new feature I get stuck, in a sense. It's not that I don't know how to implement the feature, it's that I get stuck on figuring out the best way to implement said feature. So I sit back for a day or two and let the ideas ferment until I am comfortable with a design. I get worried that I may not write something as well as it could be, or that I might have to go back and rework the whole thing; so I put it off. This is a big reason why I've never really finished many personal projects. Anyone else experience this, and how do you keep your self moving forward in your project?

• Enabling XML-documentation for code contracts

  - by DigiMortal

  One nice feature that code contracts offer is updating of code documentation. If you are using source code documenting features of Visual Studio then code contracts may automate some tasks you otherwise have to implement manually. In this posting I will show you some XML documentation files with documented contracts. I will also explain how this feature works. Enabling XML-documentation in project settings As a first thing let’s enable generating of code documentation under project settings. Open project properties, move to Build page and make check to checkbox called “XML documentation file”. Save project settings and rebuild project. When project is built go to bin/Debug folder and open the XML-file. Here is my XML. <?xml version="1.0"?> <doc>     <assembly>         <name>Eneta.Examples.CodeContracts.Testable</name>     </assembly>     <members>         <member name="T:Eneta.Examples.CodeContracts.Testable.Randomizer">             <summary>             Class for generating random integers in user specified range.             </summary>         </member>         <member name="M:Eneta.Examples.CodeContracts.Testable.Randomizer.#ctor(Eneta.Examples.CodeContracts.Testable.IRandomGenerator)">             <summary>             Constructor of Randomizer. Initializes Randomizer class.             </summary>             <param name="generator">Instance of random number generator.</param>         </member>         <member name="M:Eneta.Examples.CodeContracts.Testable.Randomizer.GetRandomFromRangeContracted(System.Int32,System.Int32)">             <summary>             Returns random integer in given range.             </summary>             <param name="min">Minimum value of random integer.</param>             <param name="max">Maximum value of random integer.</param>         </member>     </members> </doc> You can see nothing about code contracts here. Enabling code contracts documentation Code contracts have their own settings and conditions for documentation. Open project properties and move to Code Contracts tab. From “Contract Reference Assembly” dropdown check Build and make check to checkbox “Emit contracts into XML doc file”. And again – save project setting, build the project and move to bin/Debug folder. Now you can see that there are two files for XML-documentation: <assembly name>.XML <assembly name>.old.XML First files is documentation with contracts, second file is original documentation without contracts. Let’s see now what is inside our new XML-documentation file. <?xml version="1.0"?> <doc>   <assembly>     <name>Eneta.Examples.CodeContracts.Testable</name>   </assembly>   <members>     <member name="T:Eneta.Examples.CodeContracts.Testable.Randomizer">       <summary>             Class for generating random integers in user specified range.             </summary>     </member>     <member name="M:Eneta.Examples.CodeContracts.Testable.Randomizer.#ctor(Eneta.Examples.CodeContracts.Testable.IRandomGenerator)">       <summary>             Constructor of Randomizer. Initializes Randomizer class.             </summary>       <param name="generator">Instance of random number generator.</param>     </member>     <member name="M:Eneta.Examples.CodeContracts.Testable.Randomizer.GetRandomFromRangeContracted(System.Int32,System.Int32)">       <summary>             Returns random integer in given range.             </summary>       <param name="min">Minimum value of random integer.</param>       <param name="max">Maximum value of random integer.</param>       <requires description="Min must be less than max" exception="T:System.ArgumentOutOfRangeException">                 min &lt; max</requires>       <exception cref="T:System.ArgumentOutOfRangeException">                 min &gt;= max</exception>       <ensures description="Return value is out of range">                 Contract.Result&lt;int&gt;() &gt;= min &amp;&amp;                 Contract.Result&lt;int&gt;() &lt;= max</ensures>     </member>   </members> </doc> As you can see then code contracts are pretty well documented. Messages that I provided with code contracts are also available in documentation. If I wrote very good and informative messages then these messages are very useful also in contracts documentation. Code contracts and Sandcastle Sandcastle knows nothing about code contracts by default. There is separate package of file for Sandcastle that is provided you by code contracts installation. You can read from code contracts manual: “Sandcastle (http://www.codeplex.com/Sandcastle) is a freely available tool that generates help les and web sites describing your APIs, based on the XML doc comments in your source code. The CodeContracts install contains a set of les that can be copied over a Sandcastle installation to take advantage of the additional contract information. The produced documentation adds a contract section to methods with declared requires and/or ensures. In order for Sandcastle to produce Contract sections, you need to patch a number of files in its installation. Please refer to the Sandcastle Readme.txt found under Start Menu/CodeContracts/Sandcastle for instructions. A future release of Sandcastle will hopefully support contract sections without the need for this patching step.” Integrating code contracts documentation to Sandcastle will be one of my next postings about code contracts. Conclusion if you are using code documentation then documentation about code contracts can be added to documentation very easily. All you have to do is to enable XML-documentation for contracts and build your project. Later you can use Sandcastle files provided by code contracts installer to integrate contracts documentation to your output documentation package.

  Just out of curiosity, I want to know opensource tools or projects that can add some interesting features to indie games, preferably those that could only be found on big-budget games. EDIT: As suggested by The Communist Duck and Joe Wreschnig, I'm putting the examples as answers. EDIT 2: Please do not post tools like PyGame, Inkscape, Gimp, Audacity, Slick2D, Phys2D, Blender (except for interesting plugins) and the like. I know they are great tools/libraries and some would argue essential to develop good games, but I'm looking for more rare projects. Could be something really specific or niche, like generating realistic trees and plants, or realistic AI for animals.

• Exposing business logic as WCF service

  - by Oren Schwartz

  I'm working on a middle-tier project which encapsulates the business logic (uses a DAL layer, and serves a web application server [ASP.net]) of a product deployed in a LAN. The BL serves as a bunch of services and data objects that are invoked upon user action. At present times, the DAL acts as a separate application whereas the BL uses it, but is consumed by the web application as a DLL. Both the DAL and the web application are deployed on different servers inside organization, and since the BL DLL is consumed by the web application, it resides in the same server. The worst thing about exposing the BL as a DLL is that we lost track with what we expose. Deployment is not such a big issue since mostly, product versions are deployed together. Would you recommend migrating from DLL to WCF service? If so, why? Do you know anyone who had a similar experience?

• How to go about unused CSS issues

  - by Saif Bechan

  I am running some speedtests on a blog, and I always get complaints about unused CSS. But this is not CSS that I never use, it is just not used on that particular page. Now I work in a structured way, but there still has to be some CSS in the file that will not be used, because you need it on another page. I do not think that using different CSS files on different pages is the way to go, I think you are much better off just creating one big file that can be cached. Now is there an elegant way of dealing with this, or do you just stick with it.

• Security issue about making my code public in GitHub

  - by John Doe

  I'm developing a big community/forum website and I'd like to upload my code to GitHub to have at least some sort of version control over it (because I have nothing other than a .rar file as a backup, not even SVN), to let others contribute to the project, and also perhaps using it to let my potential future employers see some of my code as some sort of curriculum. But what I'm wondering now, and I'm suprised I haven't seen anyone mention it before is the security aspect of it. Isn't publishing the code of a website a HUGE security hole? Is like giving a potential hacker or anyone who would like to find any potential exploit possible, even considering that the critical files aren't uploaded (database passwords, authentication scripts, etc.). Of course that there are millions of projects uploaded to GitHub and no one will find mine just 'by chance'. But if they look for it, it would indeed be there. Bottomline: my problem is not about copyright or licenses, but others finding exploits in my website. I'm I missing something here?

• X technology is dead

  - by Daniel Moth

  Every so often, technology pundits (i.e. people not involved in the game, but who like commenting about it) throw out big controversial statements (typically to increase their readership), with a common one being that "Technology/platform X is dead". My former colleague (who I guess is now my distant colleague) uses the same trick with his blog post: "iPhone 4 is dead". But, his motivation is to set the record straight (and I believe him) by sharing his opinion on recent commentary around Silverlight, WPF etc. I enjoyed his post and the comments, so I hope you do too :-) Comments about this post welcome at the original blog.

• how to create 2D collision detection

  - by Aidan Mueller

  I would like to know the best or most effective way to test for 2D collision. I also can do AABBs but when you have a line, for example, that is rotated 45º, and it is really long. it will be hitting things when it shouldn't. I might be able to go through the pixels to see if they are touching others, but that might be slow if I had a big picture. and it might add some complications if I had a movie clip made of several images. How do I check collision between two Images? How would I do circle to box? Please help : ) PS: I do know java so you can write with java syntax and then use a made up GL

• Must-do activities for a team leader, and time managing them

  - by MeLight

  This is a two part question Part one: I'm leading a small team of developers of mixed skills (juniors and seniors). I'm sometimes feeling that I focus too much on my own code, instead of seeing the big the picture, and managing the team. What would you say the most crucial non-coding activities for a team leader, related to his team members? Part two:Given that I know what other (non-coding stuff) I should be doing, what is a good time division between my own code writing and managing the other team members (code reviews, whiteboarding, meetings etc).

• Technologie Roadmap: Portlet JSR286 vs Widget/Gadget

  - by Aerosteak

  Hello IBM got me confused (again). For many years IBM have been pushing for Portlet Containers with the JSR 168 and later the JSR 286 Specification. 2008-2009, IBM the Lotus division introduced the iWidget Specification. Based on my reading, it is a more dynamic and lightweight version of the Portlets, close to Google Gadget. It uses a different paradigm than Porlet while providing the same features. A major differentiator with this kind of client side technologies is that you don’t need a big and costly Portal infrastructure. To not fall in the ‘It depends on needs’ discussions, let consider the following: * New company, no legacy portlet, no portal in place. What are your thoughts on this?

• expand window to free space on screen in kde

  - by Pascal Rosin

  I am using Kubuntu and I want to expand the current window to the free space on the screen or to say it more precisely: I want to make the current window as big as possible without overlapping new windows (windows already overlapped should be ignored). Is there a keyboard shortcut or an extension to the KDE Window management, that realizes such a shortcut or a window button? I would also appreciate a hint, how to write a script that could do this window thing on keyboard shortcut invocation. I am a programmer but don't know what the best way is to control KDE Windows via script.

• Best memory allocation strategy for iOS ?

  - by Mr.Gando

  Hey guys, I'm debating myself about memory allocation on iOS. I write most of my code in C++ and I really like using ObjectPools, FreeLists, etc. In order to pre-allocate a lot of the stuff that I'll be constantly "alloc/dealloc" during the course of my game, ( like particles, game entities, etc ). Still on iOS, it's not like we are developing for a console like PSP, where I can know for fact that I'll get a fixed amount of memory. iOS , will issue "memory warnings" when the system needs memory. Does anyone have some suggestions about this ? Is it too serious since the new iPod touch/iPhone 4 are carrying more RAM ? or it's still a big concern ? Thanks!

• Future of Programmers [closed]

  - by Brian Paul

  Possible Duplicate: Will programmers be around in a few years? I have a passion of web development, but have been wondering of late, what is the future of web programming, and just programming in general. I will give an example to illustrate this, companies now most of them buy/ are willing to spend more money to implement enterprise level products, coming from big companies, than hiring a programmer, because when you look at the long term,instead of paying this programmer, and being tied to his ideas and skills, better buy a product, which you are guaranteed high level functions and support. Therefore what will be the future to programmers?
