• How much to pay for artwork in an indie game?

  - by f20k

  I am an indie developer and I need some detailed artwork. How much is reasonable to pay an artist for say 20 character designs? I know it depends on the artist's skills, etc, but I am wondering what to expect so that I can budget it. Edit: Let's say cartoon-ish art (Example - not necessarily in that level of detail but that kind of cartoony-art style). No 3-d modelling - The art will be used as still images in game and for promotional reasons. I'd provide a base sprite design for them to expand on and detail. Also, some numbers would be nice - I like numbers. Even a range is helpful. Like: expect to spend $x2 ~ $x1 for top-notch and $y2 ~ $y1 for decent quality. I understand I can ask at some indie-help site but, if an artist says something like $1000 for 20 designs, I wouldn't have any idea if it's reasonable / good deal / bad idea etc.

• What happened to GremCheck? Is there a viable replacement?

  - by goober

  [Cross-posted on StackOverflow, but thought it would receive a better response here. Thanks!] Hi all, I was a big fan of an app called "GremCheck" that was out a while back, that seems to have disappeared. It was a JavaScript included in a master page that placed an icon at the bottom of the page. It was used during testing. You could define your own tests, and the box could pop up per page and viewers would answer the questions you define (such as "Does this page have the correct title?", "Is the Grammar Correct", "Does the design look consistent"). This was useful for end-user tests groups and quick testing for developers if time was squeezed on full functional testing. Anyone know where GremCheck went, if I can get to it, and if there's anything out there that does something similar? Thanks for any help you can give!

• What factors influence you to try out a new framework or tool?

  - by VirtuosiMedia

  I'm in the process of putting the final touches on an open-source framework that I hope to release in the next few months. It's something that I'd like to develop a community for and so I'm curious about what factors influence your decision to use a new framework or tool and why. Some of the specific things I'd like to know more about (feel free to add to this): Types of documentation/tutorials/instruction Community support (comments/forum) Updates (blog/social media/feeds) Look and feel of the project website design White papers/testimonials A big feature list Community size Tools Ability to contribute Project test coverage (stability/security) Level of buzz (recommended by friends or around the web) Convincing marketing copy Ideally, I'd like to have all of the above, but what specific features/qualities will carry greater weight in getting programmers to adopt something new? What says, 'This is a professional-grade project,' and what are red flags that keep you from trying it out?

• Naming conventions for newtype deconstructors (destructors?)

  - by Petr Pudlák

  Looking into Haskell's standard library we can see: newtype StateT s m a = StateT { runStateT :: s -> m (a, s) } newtype WrappedMonad m a = WrapMonad { unwrapMonad :: m a } newtype Sum a = Sum { getSum :: a } Apparently, there (at least) 3 different prefixes used to unwrap a value inside a newtype: un-, run- and get-. (Moreover run- and get- capitalizes the next letter while un- doesn't.) This seems confusing. Are there any reasons for that, or is that just a historical thing? If I design my own newtype, what prefix should I use and why?

• Are C or C++ The Only Viable Languages for a GC

  - by user95312

  Background I have just finished writing a compiler for a functional language compiling to the JVM as a learning project. However, since I'm just doing this to learn, I thought it might be interesting to write a native backend and a RTS for it. As I've been planning out what this new backend will look like, the one point I'm stumbling on is the garbage collector. I've implemented the compiler in Haskell. But I have no desire to write the GC in Haskell since, while it may be possible, it'd suck. Question I've looked at several FOSS garbage collectors prior to posting and most of them were implemented in good old ANSI C. Is this still the most accepted choice for writing a GC nowadays? I've seen that this site tends to frown upon questions with multiple answers so I hope this will make it more specific: If some startup was writing a professional grade gc today, are the only viable choice for them C or C++? It's my first question here so please comment and let me know if this question is ill-suited for for programmers.

• Building a Java CMS - What Existing Product Should I Use?

  - by walnutmon

  I'm a Java developer and in need of a CMS. I've spent a lot of time reading about, and tinkering with Liferay but am concerned that it doesn't cover two of my three major concerns I need to have many sites with individual domains HTML/CSS designers need to be able to design the website templates, look and feel, and layouts in their own tools without having to worry about writing scripts Site and page building APIs must be understandable so that a custom builder interface can be created and harness the CMS as opposed to hacking it Liferay nails the first bullet point, but the second two appear to be unsolved. Does anyone have experience with a Java CMS that does all three? Or have any idea how to approach the problem if none exists? Has someone has used a Java CMS and has been able to add this functionality give some insight?

• LL(8) and left-recursion

  - by Peregring-lk

  I want to understand the relation between LL/LR grammars and the left-recursion problem (for any question I know parcially the answer, but I ask them as I don't know nothing, because I am a little confused now, and prefer complete answers) I'm happy with sintetized or short and direct answers (or just links solving it unambiguously): What type of language isn't LL(8) languages? LL(K) and LL(8) have problems with left-recursion? Or only LL(k) parsers? LALR(1) parser have troubles with left or right recursion? What type of troubles? Only in terms of the LL/LALR comparision. What is better, Bison (LALR(1)) or Boost.Spirit (LL(8))? (Let's suppose other features of them are irrelevant in this question) Why GCC use a (hand-made) LL(8) parser? Only for the "handling-error" problem?

• PostgreSQL, Ubuntu, NetBeans IDE (Part 2)

  - by Geertjan

  Now let's create the start of a CRUD application on the NetBeans Platform, using Hibernate and PostgreSQL to do so. Here's what I see in NetBeans IDE after setting things up as outlined yesterday: The NetBeans Platform CRUD Tutorial should get you up and started creating the NetBeans Platform application. Open the generated "persistence.xml" in Design mode and then switch the persistence library to Hibernate. The Here's the application structure: The Hibernate module that you see above has this content: Here's the result: And here's the source code: http://java.net/projects/nb-api-samples/sources/api-samples/show/versions/7.3/misc/NBPostgreSQL

• Catching typos or other errors in web-based scripting languages

  - by foreyez

  Hi, My background is mainly strongly typed languages (java, c++, c#). Having recently gotten back to a bit of javascript, I found it a bit annoying that if I misspell something by accident (for example I'll type 'myvar' instead of 'myVar') my entire script crashes. The browser itself most of the time doesn't even tell me I have an error, my program will just be blank, etc. Then I have to hunt down my code line by line and find the error which is very time consuming. In the languages I am used to the compiler lets me know if I made a typo. My question to you is, how do you overcome this issue in scripting (javascript)? Can you give me some tips? (this question is mainly aimed at people that have also come from a strongly typed language). Note: I mainly use the terminal/VIM ... this is mainly b/c I like terminal and I SSH alot too

• CLR via C# - first post of many!

  - by TATWORTH

  I am currently reading CLR via C# ISBN 978-0-7356-2704-8. Whilst quite correctly described by the publisher as a "Deep Dive", this is a book that C# developers with 6-18 months plus experiance ought to read. Certainly any serious Microsoft programming shop ought to have a copy.  For our VB.NET bretheren, a book of this quality is a good excuse to learn C#. (And before you ask, my favourite language of C# and VB.NET is the one that gets me the next contract!) When I started programming 31 years ago I went through IBM 360 Orientation - this gave me an comprehension of what worked best at the machine code level - this is the first book I have found that explains the the working of the Dot Net framework to explain why particular choices are good, This is my first blog post here. In the coming weeks, I intend to: Carry on with my review of CLR via C# and bring out practical points from that work. Post details of useful utilities Post some "Tales from the coal face.."

• We Heart Discussion Forums (and Know You Do Too)

  - by oracletechnet

  It's not generally known, but Oracle (via Oracle Technology Network) hosts one of the largest discussion forums instances (forums.oracle.com) on the planet (founded in 2001), containing nearly 10 million messages from 1 million registered users. That's a whole lot of conversations! And we really, really value those conversations - they span almost every conceivable technical subject across hundreds of products and technologies. More often not - and this is by design - those discussions are stewarded by community volunteers, many of whom are Oracle ACEs (who in fact earned their ACE stripes that way). And so, I am very happy to tell you that we have just initiated a project with our platform partner, Jive Software, to upgrade that platform to the most current, modern version available. The end result should be a vastly improved user experience for everyone involved, in all dimensions. There are many, many details to work on in coming weeks, but we'll keep you posted - and, when needed, come back to you for advice and suggestions. For now, we just wanted to share the good news!

• What Book-Library Organizing Programs are available?

  - by el10780

  I would like to ask if there is any good program for ubuntu 12.04 to organize a library of books.I want to mention that I also have books written in my native language (Greek) and I have books written in other languages like English,French, etc too .So basically I need an application which can fetch information from databases for Greek books. For example - Adding a Greek (ISBN) book database source and when I type the ISBN of the book in the program ,it should find the book from that databases. Is this possible? I already tried Tellico and GCstar but they were unable to find books with Greek ISBN .I tried to add a Greek book source but it wasn't successful.

• Unit testing a text index

  - by jplot

  Consider a text index such as a suffix tree or a suffix array supporting Count queries (number of occurrences of a pattern) and Locate queries (the positions of all the occurrences of a pattern) over a given text. How would you go about unit testing such a class ? What I have in mind is to generate a big random string then extract a random substring from this big string and compare the results of both queries with naive implementations (such as string::find). Another idea I have is to find the most frequent substring of length l appearing in the original string (using perhaps a naive method) and use these substrings for testing the index. This isn't the best way, so what would be a good design of the unit tests for a text index ? In case it matters, this is in C++ using google test.

• How can a script detect if the user is idle

  - by josinalvo

  I want to check, inside a bash script (*), how much time the user of a X session has been idle The user himself does not have to be using bash, but just X. If the user just moved the mouse, for example, a good answer would be "idle for 0 seconds". If he has not touched the computer in 5 minutes, a good answer would be "idle for 300 seconds" The reason to not use xautolock straight away is to be able to implement some complex behavior. For example, if the user is idle for 10 minutes, try to suspend, if he is idle for more 5 minutes, shutoff (I know it sounds odd, but suspend does not always work here ...) (*)or could be another language.

• Concept behind SHA-1 Checksum

  - by Vishwas Gagrani

  What's the basis behind SHA-1 or SHA-2 or other Checksum algorithms? I read about it here http://en.wikipedia.org/wiki/SHA-1#Data_Integrity But I am still wondering about an answer in a layman's language. Can I understand it as a very, very compressed code that can be translated back into original data? Let's say, I have a letter written in notepad. Then the whole of my 1 A4 page size data can be converted into something like this "9b90417b6a186b6f314f0b679f439c89a3b0cdf5". So whenever I want my original data back, I can convert this back into original data? I am very sure that I am wrong here, because it is weird how data that itself contains combination of letters and numbers can be represented by smaller set of letters and numbers. Illogical! Then, what's the basic?

• Petstore using Java EE 6 ? Almost!

  - by arungupta

  Antonio Goncalves, a Java Champion, JUG leader, and a well-known author, has started building a Petstore-like application using Java EE 6. The complete end-to-end sample application will build a eCommerce website and follows the Java EE 6 design principles of simple and easy-to-use to its core. Its using several technologies from the platform such as JPA 2.0, CDI 1.0, Bean Validation 1.0, EJB Lite 3.1, JSF 2.0, and JAX-RS 1.1. The two goals of the project are: • use Java EE 6 and just Java EE 6 : no external framework or dependency • make it simple : no complex business algorithm The application works with GlassFish and JBoss today and there are plans to add support for TomEE. Download the source code from github.com/agoncal/agoncal-application-petstore-ee6. And feel free to fork if you want to use a fancy toolkit as the front-end or show some nicer back-end integration. Some other sources of similar end-to-end applications are: • Java EE 6 Tutorial • Java EE 6 Galleria • Java EE 6 Hands-on Lab

• LibreOffice Spell Checker doesn't work?

  - by Michael

  I was a little surprised to discover that in LibreOffice (3.5.4.2), the spell check doesn't actually work. I was surprised since spell checkers have been around since....80's? Not a difficult thing. I am running Ubuntu 12.04, on a relatively new install. I haven't done anything to my dictionaries or language files. Under toolsoptionslanguages writing aids, I have the option selected to check as I type and to use the English dictionaries. However, I get no errors when I type spelling mistakes on purpose, and when I run the checker it just says the spell check has completed and closes the window. Is this a bug with Libre? or have I done something wrong?

• Programming for Digital frames

  - by spartan2417

  A project has recently come to my attention but i have no idea where to start or even if its possible. The idea revolves around programming a clock that is displayed inside a digital photo frame. The user would then be able to put different pictures corresponding to different times inside a usb pen for example, which would load as soon as you put the usb in. The project itself would be a really neat project - if it was just on a computer. I have no idea if what im talking about it even possible on a digital photo frame and if it is what language? Anyone who has any input at all would be great. My current idea is to maybe have a small device at the back, SSD, that runs the program through a screen, completely by passing standard digital photo frames, again though i dont know how to begin with this. And yes ive tried google (although it helps to know what to google).

• How to prepare for the GRE Computer Science Subject Test?

  - by Maddy.Shik

  How do I prepare for the GRE Computer Science subject test? Are there any standard text books I should follow? I want to score as competitively as possible. What are some good references? Is there anything that top schools like CMU, MIT, and Standford would expect? For example, Cormen et al is considered very good for algorithms. Please tell me standard text books for each subject covered by the test, like Computer Architecture, Database Design, Operating Systems, Discrete Maths etc.

• Security Alert for CVE-2011-5035 Updated

  - by Eric P. Maurice

  Hi, this is Eric Maurice again.  Oracle has just updated the Security Alert for CVE-2011-5035 to announce the availability of additional fixes for products that were affected by this vulnerability through their use of the WebLogic Server and Oracle Container for J2EE components.  As explained in a previous blog entry, a number of programming language implementations and web servers were found vulnerable to hash table collision attacks.  This vulnerability is typically remotely exploitable without authentication, i.e., it may be exploited over a network without the need for a username and password.  If successfully exploited, malicious attackers can use this vulnerability to create denial of service conditions against the targeted system. A complete list of affected products and their versions, as well as instructions on how to obtain the fixes, are listed on the Security Alert Advisory.  Oracle highly recommends that customers apply these fixes as soon as possible.

• How do you find partners for open source projects?

  - by static_rtti

  I've created a few open-source projects in the past, and had some success. The process was generally the following: I'd start alone, create something that works, promote it, and finally (maybe) get some contributions. I have less that to contribute to open-source now, but I still have ideas and can still code :) So I wonder if there is a place or a way to meet people (online), discuss ideas and design, and then start working together on the project? The reason I'm thinking about an online way to do this, with strangers, is that while I do have programmer friends, we only very rarely have the same needs and interests at the same time. It seems to me that it would be easier to find such in match in the online global community. Any insight?

• Are IE9 really good ?

  - by anirudha

  IE9 started a campaign for kill IE6 from the core because they know that IE6 is a big trouble or  problem for them for promote 9 version of IE. so they started a campaign for killing IE6. next time they kill IE 7 , 8,9 whenever they found this old version have a big problem for them to promote next version of IE.   Why they not make a update system who automatically update the browser and tell user to restart and update goes installed in the user system. well IE9 should learn from all other that they have very well design auto-update system who never give user in trouble that your browser goes old. Chrome and Firefox both update themselves and say user restart to enjoy another good version. in IE6 a big problem is that updates. no one sure that they installed new version of IE6 without any hassles and update goes install without any problem because they really know or care about “you need this to install this and this for this” so they thing “why I update IE whenever I am unsure that my browser goes update and I have no problem again” so they do nothing because their work done with no problem because common person used high profile application who work even in IE6. so they do nothing.    IE6 countdown website have designed a banner for warn or force user to upgrade to next version of IE. well there is no good reason for put the banner on website some of reason are:-   Windows 7 comes with pre-installed IE8 and Vista comes with upgrade version them IE6 so that is sure that you force a user who have Windows XP [luna] and if they want to upgrade IE then they can get IE8 not version 9 because IE9 is design for Windows 7 or Vista Service pack 2. so What is the use of update when user still have a outdate version too because IE8 is old version and not have any capability of HTML5 so forcing user by using the banner have no sense. I am not know why they all listed on website put the banner on their own website. it’s good that you offer user what they want instead of giving them a outdate version of IE again. My means to give a user list of browser they can try to enhance their browser experience instead of only IE.   IE9 build upon WPF and they spent more time on using WPF in IE instead of making user experience browser.  many thing is designed wrongly in IE first thing is tabs. the tabs in chrome are bigger and easily to move and same in Firefox even not have smooth tabbing. IE have same tabbing as chrome have but leak a point that it’s too small. if you really  want to move then sometime they create a problem that they going elsewhere from the current instance of IE.   Chrome have a big buttons, tabs and menu to enhance browser experience and Firefox have a good feature that you can make them bigger or small. you can put the icon for add-ons on the toolbar for easily use but IE have no relation with customization so we never can thinking about that.   When chrome provide lot’s of extensions and a  webstore for browser application and same feature in Firefox can be seen then there is no plugin in IE. really you can see their IE addons Website where no plugin listed for web development. even in the category or tag. as a response from many blog there is new for developer that new version of IE9 developer tool. well IE9 have three new tabs a blogger tell on their blog. when I trying them I found many thing but I still unable to edit the Css from the HTML tab and no plugin I found I can get to enhance IE9 web development. something more other provide never IE9 give me like personas , customization , browser extension or any other they used to tell a small thing customization  .   IE9 still have some problem with JavaScript that when I use Firefox and chrome and logout in both then my cookie is deleted but in IE it’s not done. it’s show me that IE9 still have different from other not for good thing even some bad thing too. When I trying to read a article that is written in Hindi using Unicode font I found that they show many thing misspelled. there is three Sha in Hindi but they all goes wrong in IE. the misprint thing is not that the writing  for the articles goes wrong. it’s problem or browser to rendering a font. the Firefox and chrome not give me this problem even opera render the font in italic style by decrease the font-size but all those work perfect.   in Pwn2Own the apple’s safari  and IE9 both are hacked. this is a awesome news for whose who thing that  open-source is lose in  Security and close-source is highly-secured software. well this is not a good parameter for talking about software. it’s should depend how much application tested and used. because more testing and more use of application make them better.   I  appreciate IE to making their new version 9 and good luck for them. there is a another matter that I personally found nothing on them.

• Why does Facebook convert PHP code to C++?

  - by user72245

  I read that Facebook started out in PHP, and then to gain speed, they now compile PHP as C++ code. If that's the case why don't they: Just program in c++? Surely there must be SOME errors/bugs when hitting a magic compiler button that ports PHP to c++ code , right? If this impressive converter works so nicely, why stick to PHP at all? Why not use something like Ruby or Python? Note -- I picked these two at random, but mostly because nearly everyone says coding in those languages is a "joy". So why not develop in a super great language and then hit the magic c++ compile button?
