• How do I get the icons of TinyMCE to show?

  - by ggfan

  I installed TinyMCE and I have the textbox and the functions work(such as , ) but I don't see the tool box that has displays all the functions. Like in this example. How do I get the images to show? All I have is the textbox. I used the code from the example link and theirs has the images and all I have is the textbox. What part do I edit to be able to see the icons? //my source link <script type="text/javascript" src="/tinymce/jscripts/tiny_mce/tiny_mce.js"> tinyMCE.init({ // Example content CSS (should be your site CSS) content_css : "style12.css", // Drop lists for link/image/media/template dialogs template_external_list_url : "/tinymce/examples/lists/template_list.js", external_link_list_url : "/tinymce/examples/lists/link_list.js", external_image_list_url : "/tinymce/examples/lists/image_list.js", media_external_list_url : "/tinymce/examples/lists/media_list.js",

• Install usblib package - Ubuntu

  - by Tom celic

  I need the package libusb for another package I am installing. I tried the following which seemed to install the package, sudo apt-get install libusb-dev but when I try to install the other package I get, configure: error: Package requirements (libusb-1.0 >= 0.9.1) were not met: No package 'libusb-1.0' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables LIBUSB_CFLAGS and LIBUSB_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. When I run the command dpkg -L libusb-dev, I get: /. /usr /usr/bin /usr/bin/libusb-config /usr/include /usr/include/usb.h /usr/lib /usr/lib/libusb.a /usr/lib/libusb.la /usr/lib/pkgconfig /usr/lib/pkgconfig/libusb.pc /usr/share /usr/share/doc /usr/share/doc/libusb-dev /usr/share/doc/libusb-dev/html /usr/share/doc/libusb-dev/html/index.html /usr/share/doc/libusb-dev/html/preface.html /usr/share/doc/libusb-dev/html/intro.html /usr/share/doc/libusb-dev/html/intro-overview.html /usr/share/doc/libusb-dev/html/intro-support.html /usr/share/doc/libusb-dev/html/api.html /usr/share/doc/libusb-dev/html/api-device-interfaces.html /usr/share/doc/libusb-dev/html/api-timeouts.html /usr/share/doc/libusb-dev/html/api-types.html /usr/share/doc/libusb-dev/html/api-synchronous.html /usr/share/doc/libusb-dev/html/api-return-values.html /usr/share/doc/libusb-dev/html/functions.html /usr/share/doc/libusb-dev/html/ref.core.html /usr/share/doc/libusb-dev/html/function.usbinit.html /usr/share/doc/libusb-dev/html/function.usbfindbusses.html /usr/share/doc/libusb-dev/html/function.usbfinddevices.html /usr/share/doc/libusb-dev/html/function.usbgetbusses.html /usr/share/doc/libusb-dev/html/ref.deviceops.html /usr/share/doc/libusb-dev/html/function.usbopen.html /usr/share/doc/libusb-dev/html/function.usbclose.html /usr/share/doc/libusb-dev/html/function.usbsetconfiguration.html /usr/share/doc/libusb-dev/html/function.usbsetaltinterface.html /usr/share/doc/libusb-dev/html/function.usbresetep.html /usr/share/doc/libusb-dev/html/function.usbclearhalt.html /usr/share/doc/libusb-dev/html/function.usbreset.html /usr/share/doc/libusb-dev/html/function.usbclaiminterface.html /usr/share/doc/libusb-dev/html/function.usbreleaseinterface.html /usr/share/doc/libusb-dev/html/ref.control.html /usr/share/doc/libusb-dev/html/function.usbcontrolmsg.html /usr/share/doc/libusb-dev/html/function.usbgetstring.html /usr/share/doc/libusb-dev/html/function.usbgetstringsimple.html /usr/share/doc/libusb-dev/html/function.usbgetdescriptor.html /usr/share/doc/libusb-dev/html/function.usbgetdescriptorbyendpoint.html /usr/share/doc/libusb-dev/html/ref.bulk.html /usr/share/doc/libusb-dev/html/function.usbbulkwrite.html /usr/share/doc/libusb-dev/html/function.usbbulkread.html /usr/share/doc/libusb-dev/html/ref.interrupt.html /usr/share/doc/libusb-dev/html/function.usbinterruptwrite.html /usr/share/doc/libusb-dev/html/function.usbinterruptread.html /usr/share/doc/libusb-dev/html/ref.nonportable.html /usr/share/doc/libusb-dev/html/function.usbgetdrivernp.html /usr/share/doc/libusb-dev/html/function.usbdetachkerneldrivernp.html /usr/share/doc/libusb-dev/html/examples.html /usr/share/doc/libusb-dev/html/examples-code.html /usr/share/doc/libusb-dev/html/examples-tests.html /usr/share/doc/libusb-dev/html/examples-other.html /usr/share/doc/libusb-dev/copyright /usr/share/doc-base /usr/share/doc-base/libusb-dev /usr/share/man /usr/share/man/man1 /usr/share/man/man1/libusb-config.1.gz /usr/lib/libusb.so /usr/share/doc/libusb-dev/changelog.Debian.gz Any ideas??

• NHibernate 2 Beginner's Guide Review

  - by Ricardo Peres

  OK, here's the review I promised a while ago. This is a beginner's introduction to NHibernate, so if you have already some experience with NHibernate, you will notice it lacks a lot of concepts and information. It starts with a good description of NHibernate and why would we use it. It goes on describing basic mapping scenarios having primary keys generated with the HiLo or Identity algorithms, without actually explaining why would we choose one over the other. As for mapping, the book talks about XML mappings and provides a simple example of Fluent NHibernate, comparing it to its XML counterpart. When it comes to relations, it covers one-to-many/many-to-one and many-to-many, not one-to-one relations, but only talks briefly about lazy loading, which is, IMO, an important concept. Only Bags are described, not any of the other collection types. The log4net configuration description gets it's own chapter, which I find excessive. The chapter on configuration merely lists the most common properties for configuring NHibernate, both in XML and in code. Querying only talks about loading by ID (using Get, not Load) and using Criteria API, on which a paging example is presented as well as some common filtering options (property equals/like/between to, no examples on conjunction/disjunction, however). There's a chapter fully dedicated to ASP.NET, which explains how we can use NHibernate in web applications. It basically talks about ASP.NET concepts, though. Following it, another chapter explains how we can build our own ASP.NET providers using NHibernate (Membership, Role). The available entity generators for NHibernate are referred and evaluated on a chapter of their own, the list is fine (CodeSmith, nhib-gen, AjGenesis, Visual NHibernate, MyGeneration, NGen, NHModeler, Microsoft T4 (?) and hbm2net), examples are provided whenever possible, however, I have some problems with some of the evaluations: for example, Visual NHibernate scores 5 out of 5 on Visual Studio integration, which simply does not exist! I suspect the author means to say that it can be launched from inside Visual Studio, but then, what can't? Finally, there's a chapter I really don't understand. It seems like a bag where a lot of things are thrown in, like NHibernate Burrow (which actually isn't explained at all), Blog.Net components, CSS template conversion and web.config settings related to the maximum request length for file uploads and ending with XML configuration, with the help of GhostDoc. Like I said, the book is only good for absolute beginners, it does a fair job in explaining the very basics, but lack a lot of not-so-basic concepts. Among other things, it lacks: Inheritance mapping strategies (table per class hierarchy, table per class, table per concrete class) Load versus Get usage Other usefull ISession methods First level cache (Identity Map pattern) Other collection types other that Bag (Set, List, Map, IdBag, etc Fetch options User Types Filters Named queries LINQ examples HQL examples And that's it! I hope you find this review useful. The link to the book site is https://www.packtpub.com/nhibernate-2-x-beginners-guide/book

• Color schemes generation - theory and algorithms

  - by daniel.sedlacek

  Hi I will be generating charts and diagrams and I am looking for some theory on color schemes and algorithm examples. Example questions: How to generate complementary or analogous colors? How to generate pastel, cold and warm colors? How to generate any number of random but distinct colors? How to translate all that to the hex triplet (web color)? My implementation will be in AS3 but any examples in metacode are welcome.

• Bohemia Interactive's bio2s format

  - by Jaime Soto

  Does anyone have specifications for the bio2s scripting language from Bohemia Interactive? They develop Operation Flashpoint, Armed Assault (ArmA), and Virtual Battlespace. These scripts are sometimes called O2 or Oxygen scripts and are used in their terrain and modeling tools. Oxygen is Bohemia Interactive's modeling tool. I found additional examples of the format in this VBS2 tutorial and this ArmA forum thread. EDIT: I clarified the purpose of the bio2s format and provided some links to examples.

• In-Game Encyclopedias

  - by SHiNKiROU

  There are some games where there is an in-game encyclopedia where you can know many things about characters and settings of the game. For example, the Codex in Mass Effect. I want to know if it is exclusive to Bioware, and get inspired about other encyclopedia systems. What are some other examples of in-game encyclopedias? How effective is it? I also want some examples where the in-game encyclopedia is not effective at all or an ignored feature

• Making large scale changes to an economy in a social game

  - by Zach

  Are there any examples or case studies of social games, specifically on Facebook, where the developer has made drastic changes to the economy? I'm specifically interested in examples where the old economy was based off of purchasing items with Facebook credits then moving to a new model where the same inventory or similar inventory is sold with a soft currency. The closest comparisons I've been able to find so far are looking at iOS games that have gone from purchase models to freemium models, but haven't found a comparable scenario in a social game besides larger scale MMO's.

• Do you have to be good at math to be a good programmer?

  - by Charles Roper

  It seems that conventional wisdom suggests that good programmers are also good at math. Or that the two are somehow intrinsically linked. Many programming books I have read provide many examples that are solutions to math problems, or are somehow related to math as if these examples are what make sense to most people. So the question I would like to float is: do you have to be good at math to be a good programmer?

• Interactive Fiction engine and Tech Support - has anyone done this? [on hold]

  - by Larry G. Wapnitsky

  I've always been a big fan of Interactive Fiction and have been wanting to try my hand at it for a while. I have a need to create a decision tree for my tech support group (L1-L3) and feel as though presenting a decision tree in the form of an IF game would be rather interesting and helpful. I plan on using Inform7, but am curious if anyone has done anything like this in the past. If so, can you present examples, links to examples, opinions? Thanks, Larry

• writing programs without compiler?

  - by Matt

  I am not sure if this is even possible but I have watched a few videos with programming examples where it seems like the program is being written in some kind of command prompt rather than a nice graphical compiler. Im just curious as to what might be going on in these videos. Is it possible to write a program without a compiler? heres two examples: http://www.youtube.com/watch?v=hFSY9cWjO8o( @ 6 min) http://www.youtube.com/watch?v=tKTZoB2Vjuk (@ 5 min) Could anyone explain how this is done?

• Changing Ogre3D terrain lighting in real time

  - by lezebulon

  I'm looking at the Ogre 3D library and I'm browsing through some examples / tutorials. My question is about terrain. There are a few examples showing how great the terrain system is, but I think that the global illumination and shadows of the terrain have to be pre-computed, which kinda makes it impossible to integrate this with a day / night cycle. Is there a way to change the terrain light sources in real time? If so it is possible to do it and keep a decent FPS?

• MMORPG game balancing

  - by Gary Paluk

  I've seen a couple of examples of some game balancing techniques in books yet they are not comprehensive and not particularly aimed at MMORPGs but I'm looking for practical examples of game balancing techniques for MMORPGs. I am interested to know if anyone has documented the techniques used in popular games with proven success in this area. Ideally, any resource would cover most common types of stats and include layman mathematical models or techniques used to balance game mechanics found in advanced MMORPGs (I know it's a cliché, but WoW style) Any help would be great!

• Mod_Proxy_AJP set up issues

  I'm trying to set up Tomcat behind Apache using mod_proxy_ajp. After tons of messing around with the configs I am stuck at a 403 page when trying to access tomcat.

• Book Review - Programming Windows Azure by Siriram Krishnan

  - by BuckWoody

  As part of my professional development, I’ve created a list of books to read throughout the year, starting in June of 2011. This a review of the first one, called Programming Windows Azure by Siriram Krishnan. You can find my entire list of books I’m reading for my career here: http://blogs.msdn.com/b/buckwoody/archive/2011/06/07/head-in-the-clouds-eyes-on-the-books.aspx  Why I Chose This Book: As part of my learning style, I try to read multiple books about a single subject. I’ve found that at least 3 books are necessary to get the right amount of information to me. This is a “technical” work, meaning that it deals with technology and not business, writing or other facets of my career. I’ll have a mix of all of those as I read along. I chose this work in addition to others I’ve read since it covers everything from an introduction to more advanced topics in a single book. It also has some practical examples of actually working with the product, particularly on storage. Although it’s dated, many examples normally translate. I also saw that it had pretty good reviews. What I learned: I learned a great deal about storage, and many useful code snippets. I do think that there could have been more of a focus on the application fabric - but of course that wasn’t as mature a feature when this book was written. I learned some great architecture examples, and in one section I learned more about encryption. In that example, however, I would rather have seen the examples go the other way - the book focused on moving data from on-premise to Azure storage in an encrypted fashion. Using the Application Fabric I would rather see sensitive data left in a hybrid fashion on premise, and connect to for the Azure application. Even so, the examples were very useful. If you’re looking for a good “starter” Azure book, this is a good choice. I also recommend the last chapter as a quick read for a DBA, or Database Administrator. It’s not very long, but useful. Note that the limits described are incorrect - which is one of the dangers of reading a book about any cloud offering. The services offered are updated so quickly that the information is in constant danger of being “stale”. Even so, I found this a useful book, which I believe will help me work with Azure better. Raw Notes: I take notes as I read, calling that process “reading with a pencil”. I find that when I do that I pay attention better, and record some things that I need to know later. I’ll take these notes, categorize them into a OneNote notebook that I synchronize in my Live.com account, and that way I can search them from anywhere. I can even read them on the web, since the Live.com has a OneNote program built in. Note that these are the raw notes, so they might not make a lot of sense out of context - I include them here so you can watch my though process. Programming Windows Azure by Siriram Krishnan: Learning about how to select applications suitable for Distributed Technology. Application Fabric gets the least attention; probably because it was newer at the time. Very clear (Chapter One) Good foundation Background and history, but not too much I normally arrange my descriptions differently, starting with the use-cases and moving to physicality, but this difference helps me. Interesting that I am reading this using Safari Books Online, which uses many of these concepts. Taught me some new aspects of a Hypervisor – very low-level information about the Azure Fabric (not to be confused with the Application Fabric feature) (Chapter Two) Good detail of what is included in the SDK. Even more is available now. CS = Cloud Service (Chapter 3) Place Storage info in the configuration file, since it can be streamed in-line with a running app. Ditto for logging, and keep separated configs for staging and testing. Easy-switch in and switch out.  (Chapter 4) There are two Runtime API’s, one of external and one for internal. Realizing how powerful this paradigm really is. Some places seem light, and to drop off but perhaps that’s best. Managing API is not charged, which is nice. I don’t often think about the price, until it comes to an actual deployment (Chapter 5) Csmanage is something I want to dig into deeper. API requires package moves to Blob storage first, so it needs a URL. Csmanage equivalent can be written in Unix scripting using openssl. Upgrades are possible, and you use the upgradeDomainCount attribute in the Service-Definition.csdef file  Always use a low-privileged account to test on the dev fabric, since Windows Azure runs in partial trust. Full trust is available, but can be dangerous and must be well-thought out. (Chapter 6) Learned how to run full CMD commands in a web window – not that you would ever do that, but it was an interesting view into those links. This leads to a discussion on hosting other runtimes (such as Java or PHP) in Windows Azure. I got an expanded view on this process, although this is where the book shows its age a little. Books can be a problem for Cloud Computing for this reason – things just change too quickly. Windows Azure storage is not eventually consistent – it is instantly consistent with multi-phase commit. Plumbing for this is internal, not required to code that. (Chapter 7) REST API makes the service interoperable, hybrid, and consistent across code architectures. Nicely done. Use affinity groups to keep data and code together. Side note: e-book readers need a common “notes” feature. There’s a decent quick description of REST in this chapter. Learned about CloudDrive code – PowerShell sample that mounts Blob storage as a local provider. Works against Dev fabric by default, can be switched to Account. Good treatment in the storage chapters on the differences between using Dev storage and Azure storage. These can be mitigated. No, blobs are not of any size or number. Not a good statement (Chapter 8) Blob storage is probably Azure’s closest play to Infrastructure as a Service (Iaas). Blob change operations must be authenticated, even when public. Chapters on storage are pretty in-depth. Queue Messages are base-64 encoded (Chapter 9) The visibility timeout ensures processing of message in a disconnected system. Order is not guaranteed for a message, so if you need that set an increasing number in the queue mechanism. While Queues are accessible via REST, they are not public and are secured by default. Interesting – the header for a queue request includes an estimated count. This can be useful to create more worker roles in a dynamic system. Each Entity (row) in the Azure Table service is atomic – all or nothing. (Chapter 10) An entity can have up to 255 Properties  Use “ID” for the class to indicate the key value, or use the [DataServiceKey] Attribute.  LINQ makes working with the Azure Table Service much easier, although Interop is certainly possible. Good description on the process of selecting the Partition and Row Key.  When checking for continuation tokens for pagination, include logic that falls out of the check in case you are at the last page.  On deleting a storage object, it is instantly unavailable, however a background process is dispatched to perform the physical deletion. So if you want to re-create a storage object with the same name, add retry logic into the code. Interesting approach to deleting an index entity without having to read it first – create a local entity with the same keys and apply it to the Azure system regardless of change-state.  Although the “Indexes” description is a little vague, it’s interesting to see a Folding and Stemming discussion a-la the Porter Stemming Algorithm. (Chapter 11)  Presents a better discussion of indexes (at least inverted indexes) later in the chapter. Great treatment for DBA’s in Chapter 11. We need to work on getting secondary indexes in Table storage. There is a limited form of transactions called “Entity Group Transactions” that, although they have conditions, makes a transactional system more possible. Concurrency also becomes an issue, but is handled well if you’re using Data Services in .NET. It watches the Etag and allows you to take action appropriately. I do not recommend using Azure as a location for secure backups. In fact, I would rather have seen the examples in (Chapter 12) go the other way, showing how data could be brought back to a local store as a DR or HA strategy. Good information on cryptography and so on even so. Chapter seems out of place, and should be combined with the Blob chapter.  (Chapter 13) on SQL Azure is dated, although the base concepts are OK.  Nice example of simple ADO.NET access to a SQL Azure (or any SQL Server Really) database.

• Good 2D Platformer Physics

  - by Joe Wreschnig

  I have a basic character controller set up for a 2D platformer with Box2D, and I'm starting to tweak it to try to make it feel good. Physics engines have a lot of knobs to tweak, and it's not clear to me, writing with a physics engine for the first time, which ones I should use. Should jumping apply a force for several ticks? An impulse? Directly set velocity? How do I stop the avatar from sticking to walls without taking away all its friction (or do I take away all the friction, but only in the air)? Should I model the character as a capsule? A box with rounded corners? A box with two wheels? Just one big wheel? I feel like someone must have done this before! There seem to be very few resources available on the web that are not "baby's first physics", which all cut off where I'm hoping someone has already solved the issues. Most examples of physics engines for platformers have floaty-feeling controls, or in-air jumps, or easily exploitable behavior when temporary penetration is too high, etc. Some examples of what I mean: A short tap of jump jumps a short distance; a long tap jumps higher. Short skidding when stopping or reversing directions at high velocity. Standing stably on inclines (but maybe sliding down them when ducking). Analog speed when using an analog controller. All the other things that separate good platformers from bad platformers. Dare I suggest, stable moving platforms? I'm not really looking for "hey, do this." Obviously, the right thing to do is dependent on what I want in the game. But I'm hoping someone somewhere has gone through the possibilities and said "well technique A does feature X well, technique B does Y well, but that doesn't work with C", or has some worked examples beyond "if (key == space) character.impulse(0, 1)"

• Can you point me to a nontrivial strategy pattern implementation?

  - by Eugen Martynov

  We are faced implementing a registration workflow with many branches. There are three main flows which in some conditions lead to one another. Each flow has at least four different steps; some steps interact with the server, and every step adds more information to the state. Also the requirement is to have it persistent between sessions, so if the user closes the app (this is a mobile app), it will restore the process from the last completed step with the state from the previous session. I think this could benefit from the use of the strategy pattern, but I've never had to implement it for such a complex case. Does anyone know of any examples in open source or articles from which I could find inspiration? Preferably the examples would be from a live/working/stable application. I'm interested in Java implementation mostly; we are developing for Java mobile phones: android, blackberry and J2ME. We have an SDK which is quite well separated from platform specific implementations, but examples in C++, C#, Objective-C or Python would be acceptable.

• Example of persisting an inheritance relationship using ORM

  - by Schemer

  I have some experience with OOP and RDBs, but very little exposure to web programming. I am trying to understand what non-trivial types of problems are solved by ORM. Of course, I am familiar with the need for data persistence, but I have never encountered a need for persisting relationships between objects, a situation which is indicated in many online articles about ORM. I am not asking about the process of persisting a POJO to a database and restoring it later. Nor am I asking about why ORM frameworks are useful -- or a pain in the butt -- for doing so. I am particularly interested in how the need arises to persist and restore relationships between objects. In various documentation, I have seen many examples of persisting POJOs to a database, but the examples have all been for only very simple objects that are essentially nothing more than records anyway: a constructor, some private fields, and getter/setter methods. The motivation for persisting such an "object-record" seems obvious and trivial. This example: Hibernate ORM Tutorial offers such an example, but goes on to discuss mismatch issues of granularity, inheritance, identity, associations, and navigation that are not motivated by the example. If someone could offer a toy example of an instance where, say, the need arises to persist an inheritance relationship, I would be grateful. This might be blindingly obvious for anyone who has already encountered this situation but I have not and a great deal of searching and reading have not turned up any examples.

• Real life example of an agile game development process outputs

  - by Ken

  I'm trying to learn about applying agile methodologies to game development. But seems to be impossible to find real life examples. There seems to be plenty of material discussing how 'in principle' agile is applied to a game. But that is NOT what I am looking for. I have the Keith book. What I AMlooking for are real EXAMPLES of things like; Initial user stories Final user stories (complete, covering the entire game requirements) Acceptance criteria Task list Sprint backlogs (before and after each sprint) The agile books seem to have some limited examples, many of which seem contrived or limited. In this era of open source software, there must be a publicly available documented example of the process applied to a real game. I am asking specifically about games because they are so different from normal applications. Regular applications are built to all users to complete specific tasks in order to get stuff done(book a room, print a report etc). People play games for much less tangible reasons, so I think the process is significantly different. [it doesn't have to be scrum, it could be any process, just needs to be a real life example game and be reasonably complete]

• What is a good toy example to teach version control?

  - by janos

  I am looking for practical examples to use when teaching version control. Breaking down the material to basic concepts and providing examples is an obvious way to teach version control, but this can be very boring, unless the examples are really practical or interesting. One idea I have is customizing a wordpress theme. I use wordpress a lot and no theme is ever perfect, so I typically just put the theme directory in version control using any dvcs and start recording changes. The problem with this example is that not many people in the audience may be familiar with wordpress, let alone have shell access to a wordpress site to try out the commands. Preparing a mock site and giving access to everyone is also not an option for me. I need a "toy example" that can be interesting to a broad audience of software developers, and something they can try on their own computers. The tutorial will use a dvcs, but the practical example I'm looking for is only to teach the basic features of version control, ignoring the distributed features for the moment. (Now that I think of it, instead of a mock site, a customized live cd might do the trick...) Any better ideas?
