  • Player sprite moving slower on iPhone 4

    - by nvillec
    I just finished getting movement/jump animation for a player sprite in Xcode using Cocos2D. The basic movement algorithm is a timer that updates every 0.01 sec, changing the sprite position to (sprite.position.x + xVel, sprite.position.y + yVel). Each time a movement button is tapped, the appropriate velocity (initialized to 0) is changed to whatever speed I choose, then a stop movement button returns the velocity to 0. It's not an ideal solution but I'm very new at this and stoked to at least have that working with little help from the internet. So I may not have explained that perfectly, but it is in fact working to my satisfaction in Xcode's iPhone Simulator, however when I build it for my device and run it on my phone, the sprite's movement speed is noticeably slower than in Xcode. At first I thought it must have to do with the resolution of the iPhone 4, making the sprite's movement path twice as long, but I found that if I pull up the multitask bar, then return to the app the speed will sometimes jump back to normal. My second theory was that the code is just inefficient and is bogging the processes down, but I would see this reflected in the frame rate wouldn't I? It stays at 59-60 the whole time, and the spritesheet animation runs at the correct speed. Has anyone experienced this? Is this a really obvious issue that I'm completely missing? Any help (or tips for optimizing my approach to movement) would be much appreciated!

  • What are some general guidelines for setting up an iOS project I will want to personally publish but sell in the future?

    - by RLH
    I have an idea for a personal iOS project that I would like to write and release to the iOS store. I'm the type of developer who enjoys developing and publishing. I want to write quality software and take care of my customers. Assuming that I wrote an application that had reasonable success, there is a fair chance that I would want to sell the ownership rights of the app to another party and I'd use the proceeds to develop my next personal project which, in turn, I'd probably want to sell in the future. With that said, what are some general guidelines for creating, making and publishing an iOS project that I will eventually want to transfer to another company/developer? I know this is a bit of a broad question, but I request that the given advice be a general list of tips, suggestions and pitfalls to avoid. If any particular bullet point on your list needs more explanation, I'll either search for the answer or post a new question specific to that requirement. Thank you! Note Regarding this Question I am posting this question on Programmers.SO because I think that this is an issue of software architecting, seeking advice for setting a new application project and publishing a project to the Apple iOS store-- all within the requirements for questions on this site.

  • "Oracle Coherence 3.5" Book - My Humble Review

    - by [email protected]
      After reviewing the book in more detail I say again that it is a great guide for sure. Lots of important concepts that sometimes can be somewhat confusing are deeply reviewed, including all types of caching schemes and backing maps, and the cache topologies with their corresponding performances and very useful "When to use it?" sections. Some functionalities that are very desirable or used a lot are reviewed with examples and best practices of implementation, including: Data affinity Querying Pagination Indexes Aggregations Event processing, listening and triggering Data persistence Security Regarding the networking and architecture topics, Coherence*Extend is exhaustively reviewed, including C++ and .NET clients, with very good tips and examples, even including source codes. Personally, I am also glad to see that the address providers (<address-provider> tag), new feature in Coherence 3.5 which is a way to programmatically provide well-known addresses in order to connect to the cluster, is mentioned on the book, because it provides new functionalities to satisfy some special configuration requirements for example: Provide a way to switch extend nodes in cases of failure Implement custom load balancing algorithms and/or dynamic discovery of TCP/IP connection acceptors Dynamically assign TCP address and port settings when binding to a server socket Another very interesting and useful section is the "Coherent Bank Sample Application", which is a great tutorial, useful to understand how Coherence interacts with third party products establishing a clear integration with them, including the use of non-Oracle products like MS Visual Studio.

  • As a developer, how do I learn sales? [closed]

    - by Dan Abramov
    I quit the company I was working for to pursuit an opportunity as a startup, and I believe in our product. I'm sure it's going to be great if we attract some customers first to keep going. (I don't want funding.) Our product is targeted at private schools and courses, and helps organize the mess other LMSs introduce. The problem is, our team is basically just me and I have very little idea about sales and marketing. I can do reasonably good copywriting but I'm sure I can do better—and being nervous or too techy in a real world conversation with the client doesn't help. I want to get better, in fact, a lot better at negotiating with clients and pitching my product. I did look for some “sales articles” on the web, and a lot of what I found is plain bullshit on SEO-engineered websites promoting books or $5000 courses. What I need instead is a developer's perspective on how to sale a product you think is great. What are typical programmer's mistakes and misconceptions about sales, and how to avoid them? How do you evolve into a reasonably great salesman? I can't believe it's in the mindset and unlearnable. Your own experience, combined with great articles available on the web is most welcome. To Future Readers The question got closed because it is not a good fit for this site. I found some helpful tips in a similar question asked on a sister StackExchange site about startups: I'm a terrible salesperson. What can I do about it?

  • How do I parse a header with two different version [ID3] avoiding code duplication?

    - by user66141
    I really hope you can give me some interesting viewpoints for my situation, because I am not satisfied with my current approach. I am writing an MP3 parser, starting with an ID3v2 parser. Right now I`m working on the extended header parsing, my issue is that the optional header is defined differently in version 2.3 and 2.4 of the tag. The 2.3 version optional header is defined as follows: struct ID3_3_EXTENDED_HEADER{ DWORD dwExtHeaderSize; //Extended header size (either 6 or 8 bytes , excluded) WORD wExtFlags; //Extended header flags DWORD dwSizeOfPadding; //Size of padding (size of the tag excluding the frames and headers) }; While the 2.4 version is defined : struct ID3_4_EXTENDED_HEADER{ DWORD dwExtHeaderSize; //Extended header size (synchsafe int) BYTE bNumberOfFlagBytes; //Number of flag bytes BYTE bFlags; //Flags }; How could I parse the header while minimizing code duplication? Using two different functions to parse each version sounds less great, using a single function with a different flow for each occasion is similar, any good practices for this kind of issues ? Any tips for avoiding code duplication? Any help would be appreciated.

  • General List of Common Programming Errors

    - by javamonkey79
    As one journey's from apprentice to journeyman to master I've noticed that one accumulates a list of best practices for things they've been bitten by. Personally, I write most of my stuff in java & SQL so my list tends to be slated towards them. I've accumulated the following: When doing list removal, always reverse iterate Avoid adding items to a list you are currently iterating on Watch out for NullPointerExceptions Now, I know there are language specific "common errors" links out there like this one. And I'm also aware of the pragmatic programmer tips, Martin Fowler's "code smells". Does anyone know of any good lists out there of things like I've listed above (re: list removal, adding items, etc). My guess is that there are some good QA folks out there that can probably throw me a bone here. I'm not looking for things the compiler can catch - I'm looking for common things that cause bugs. In the event that there isn't a list out there already then I welcome posting your own findings here. Thanks in advance!

  • How is determined an impact of a requirement change on the existing code?

    - by MainMa
    Hi, How companies working on large projects evaluate an impact of a single modification on an existing code? Since my question is probably not very clear, here's an example: Let's take a sample business application which deals with tasks. In the database, each task has a state, 0 being "Pending", ... 5 - "Finished". A new requirement adds a new state, between 2nd and 3rd one. It means that: A constraint on the values 1 - 5 in the database must be changed, Business layer and code contracts must be changed to add a new state, Data access layer must be changed to take in account that, for example the state StateReady is now 6 instead of 5, etc. The application must implement a new state visually, add new controls for it, new localized strings for tool-tips, etc. When an application is written recently by one developer, it's more or less easy to predict every change to do. On the other hand, when an application was written for years by many people, no single person can anticipate every change immediately, without any investigation. So since this situation (such changes in requirements) is very frequent, I imagine there are already some clever techniques and ways to predict the impact. Is there any? Do you know any books which deal about this subject? Note: my question is not related to How do you deal with changing requirements? question. In fact, I'm not interested in evaluating the cost of a change, but rather the way to predict the parts of an application which will be concerned by the change. What will be those changes and how difficult they are really doesn't matter in my question.

  • Cuda driver, CPU/GPU performances issue

    - by elect
    I implemented a RNS Montgomery exponentiation in Cuda and on cpu for comparison. Everything nice everything fine. It runs on just one SM. However I am going to tell you some strange regression in both cpu/gpu performances. During the devoloping, about two month ago, I was using Cuda 5 preview on Ubuntu 11.04 64b. In this time, I reach the following performances: cpu 460ms gpu 120ms Then one day when I turn on the pc, the graphical environment didnt start. I dont know which was the problem, however I switched to the console and installed again the Cuda driver. At the following boot performances changed: cpu 310ms gpu 80ms I was like Q.Q...uhm ok, nice to see this, but I was wondering how that could be possible However, I went then in holiday for 10 days and I continued developing and optimizing on my notebook (but not the same part of the code, some additional stuff) When I was back, I just updated the source files, and performances came back to 460/120ms.. I couldnt believe it, I tried to install Cuda 5 RC, updating the video driver too... nothing changed... I checked Debug/Release, Cuda computability, but the problem seems being somewhere else.. Looking around the net I found this, I am pretty sure it must have something to do with the driver, because the performance change affected both cpu and gpu Do you have some tips/ideas/suggestions?

  • Install Base Transaction Error Troubleshooting

    - by LuciaC
    Oracle Installed Base is an item instance life cycle tracking application that facilitates enterprise-wide life cycle item management and tracking capability.In a typical process flow a sales order is created and shipped, this updates Inventory and creates a new item instance in Install Base (IB).  The Inventory update results in a record being placed in the SFM Event Queue.  If the record is successfully processed the IB tables are updated, if there is an error the record is placed in the csi_txn_errors table and the error needs to be resolved so that the IB instance can be created.It's extremely important to be proactive and monitor IB Transaction Errors regularly.  Errors cascade and can build up exponentially if not resolved. Due to this cascade effect, error records need to be considered as a whole and not individually; the root cause of any error needs to be resolved first and this may result in the subsequent errors resolving themselves. Install Base Transaction Error Diagnostic Program In the past the IBtxnerr.sql script was used to diagnose transaction errors, this is now replaced by an enhanced concurrent program version of the script. See the following note for details of how to download, install and run the concurrent program as well as details of how to interpret the results: Doc ID 1501025.1 - Install Base Transaction Error Diagnostic Program  The program provides comprehensive information about the errors found as well as links to known knowledge articles which can help to resolve the specific error. Troubleshooting Watch the replay of the 'EBS CRM: 11i and R12 Transaction Error Troubleshooting - an Overview' webcast or download the presentation PDF (go to Doc ID 1455786.1 and click on 'Archived 2011' tab).  The webcast and PDF include more information, including SQL statements that you can use to identify errors and their sources as well as recommended setup and troubleshooting tips. Refer to these notes for comprehensive information: Doc ID 1275326.1: E-Business Oracle Install Base Product Information Center Doc ID 1289858.1: Install Base Transaction Errors Master Repository Doc ID: 577978.1: Troubleshooting Install Base Errors in the Transaction Errors Processing Form  Don't forget your Install Base Community where you can ask questions to help you resolve your IB transaction errors.

  • System in low graphics, deleted linux, grub rescue, can't access windows

    - by First timer
    So I'm pretty new to Ubuntu but I managed to install it with no big problems on both my desktop and netbook. When I installed it on my brother's netbook everything went horribly wrong and now I fear the system is close to beyond repair. The problem was first that it said it did not have any space left (seemed ridiculous since it had a lot). Then Ubuntu began booting into a "System is running in low graphics mode error" which I then tried to fix, using all the tips I could find in here but nothing helped. I think the graphics error and lack of space might have been related but I can't be sure. Finally I gave up repairing Ubuntu and went for a reinstall. Shouldn't have done that! I read that I should simply open Ubuntu through a live usb and choose GParted to delete the Linux partitions so I did and rebooted accordingly. Next, I was to install Ubuntu but now I am only given the option to wipe the whole disk for Ubuntu, not install along with windows 7. If I access GParted I can still see the ntfs partitions that hold windows 7 (there are 2: one labeled RECOVERY and another labeled OS and boot) so why can't I access them? Btw. the OS and boot has a little red mark with a warning that 1 cluster is referenced to multiple times, don't know what that means. If I boot without the live usb I am sent directly into a grub rescue "black screen of the computer will follow no orders". Please, I know that the easiest might be to simply wipe the whole thing clean but there are important files and programs on windows 7. Is there a way to just access windows? It is a dell inspiron 1018 mini netbook, so I have no cd input and no windows 7 installation cd.

  • What type of pattern would be used in this case

    - by Admiral Kunkka
    I want to know how to tackle this type of scenario. We are building a person's background, from scratch, and I want to know, conceptually, how to proceed with a secure object pattern in both design and execution... I've been reading on Factory patterns, Model-View-Controller types, Dependency injection, Singleton approaches... and I can't seem to grasp or 'fit' these types of designs decisions into what I'm trying to do.. First and foremost, I started with having a big jack-of-all-trades class, then I read some more, and some tips were to make sure your classes only have a single purpose.. which makes sense and I started breaking down certain things into other classes. Okay, cool. Now I'm looking at dependency injection and kind of didn't really know what's going on. Example/insight of what kind of heirarchy I need to accomplish... class Person needs to access and build from a multitude of different classes. class Culture needs to access a sub-class for culture benefits class Social needs to access class Culture, and other sub-classes class Birth needs to access Social, Culture, and other sub-classes class Childhood/Adolescence/Adulthood need to access everything. Also, depending on different rolls, this class heirarchy needs to create multiple people as well, such as Family, and their backgrounds using some, if not all, of these same classes. Think of it as a people generator, all random, with backgrounds and things that happen to them. Ageing, death of loved ones, military careers, e.t.c. Most of the generation is done randomly, making calls to a mt_rand function to pick from most of the selections inside the classes, guaranteeing the data to be absolutely random. I have most of the bulk-data down, and was looking for some insight from fellow programmers, what do you think?

  • Install a i386 printer driver into an amd64 distribution or how can I find a good printer based on features?

    - by Yanick Rochon
    Hi, I just bought a Lexmark Interpret S408 all-in-one printer. The box said that it supported Ubuntu 8.04, but I told myself it should work with Lucid... well no. The only driver I have found is for i386 while I have a amd64 image installed; the architecture is incompatible. So, the quesiton is : Is it possible to install that driver anyway, somehow? Or do I need to take that printer back to the store and buy another one? If the latter is the only alternative, I need a printer that has wireless connection capability can do color printing is of good price (less than $200 CAD) Thank you for your answers, help, and tips. ** UPDATE ** The driver was given in the form of deb package (for Debian distributions) and I managed to extract the actual deb package driver out of the install program. I ran sudo dpkg -i --force-all lexmark-inkjet-09-driver-1.5-1.i386.deb and the driver installed, and I was able to print something out. But that pretty much ends there; I cannot access anymore of the printer settings, etc. (i.g. scanner, fax, wifi settings, etc.) I should suffice for now as I'm satisfied with the printer's features (and size, and prince), but if I could have a full-linux-supported printer like that one, I would return this one in exchange for the other.

  • How can I learn more about ADF?

    - by jhpierce -Oracle
    Look to the Oracle Technology Network for a wealth of information, tutorials, best practices and coding examples. The place to start is the Oracle Application Development Framework (ADF) web page. The Oracle ADF page has basic information and downloads for ADF, but the real wealth is in the links to other pages. One of the pages is the Oracle ADF Code Corner,  which is a blog-style column that provides hints, tips and coding examples for ADF developers. The content on this page ranges from easy to complex and often contains advanced programming concepts. The content is inspired by questions asked on the Oracle JDeveloper customer forum on OTN. The ADF Code Corner has many articles that will inspire your imagination and possibly solve your coding problem.How about the Oracle ADF Architecture Square link? The Oracle ADF Architecture Square focuses on architectural issues and developer guidelines for writing ADF software solutions. The goal is to give ADF developers an understanding of the necessary decisions for building a successful ADF application, to offer potential architectural blueprints to choose from when putting the ADF application together, and to provide potential ADF best practices to take back to your development team. The Oracle ADF Mobile link gives information on developing mobile applications for iOS and Android based applications. There are links to ADF Mobile Overview, ADF Mobile demos and ADF Mobile courses.The Sample ADF Applications link lists sample applications and other resources where you can find code samples for ADF. These are complete ADF applications that can be downloaded into JDeveloper and give you insight into coding an application.There are many more links found under the "Learn More" tab that can equip the developer with the knowledge they need to develop their applications. There are links to overview papers, technical resources, related topics and available training. The information you need IS just a click away.

  • Failure Driven Development

    - by DevSolo
    At our shop, we strive to be agile. And I'd say we are making great strides. That said, a few of us have spotted a pattern we have started calling "Failure Driven Development". Failure Driven Development can basically be desribed as an agile release/iteration cycle where the bugs/features are guided not by tasks and stories with acceptance criteria, but with defects entered in the defect tracking software. Our team has a great Project Manager who strives to get the acceptance criteria from the customer(s), but it's not always possible. From my development chair, this is due to the customer either not knowing exactly what they want or (and this is the kicker) two different "camps" at the customer's main office conflict with how a story should be implemented. Camp A will losely dictate that Feature X works like this, then Camp B will fail it due not functioning like that. Hence, the term "FDD". The process is driven by "failures". This leads to my question: Has anyone else encountered this and if so, any tips/suggestions for dealing with it? We have, of course, tried to get Camp A and B to agree prior, but everyone knows this isn't always the case. Thanks

  • How do I use an API?

    - by GRardB
    Background I have no idea how to use an API. I know that all APIs are different, but I've been doing research and I don't fully understand the documentation that comes along with them. There's a programming competition at my university in a month and a half that I want to compete in (revolved around APIs) but nobody on my team has ever used one. We're computer science majors, so we have experience programming, but we've just never been exposed to an API. I tried looking at Twitter's documentation, but I'm lost. Would anyone be able to give me some tips on how to get started? Maybe a very easy API with examples, or explaining essential things about common elements of different APIs? I don't need a full-blown tutorial on Stack Overflow; I just need to be pointed in the right direction. Update The programming languages that I'm most fluent in are C (simple text editor usually) and Java (Eclipse). In an attempt to be more specific with my question: I understand that APIs (and yes, external libraries are what I was referring to) are simply sets of functions. Question I guess what I'm trying to ask is how I would go about accessing those functions. Do I need to download specific files and include them in my programs, or do they need to be accessed remotely, etc.?

  • How do I get away from PHP in the web industry?

    - by Kurtis
    I'm just looking for some tips on getting away from using PHP for web development. I'm self-employed but it seems like all of the work I find deals with PHP. I'm not complaining about the work -- just the poor choice of a language that is incredibly popular. I'd love to do my web development in Python, Perl, C#, or even a fun and fancy functional language. There's the old saying that you don't tell a carpenter what kind of a hammer to use. At the same time, you do tell them what kind of material to build your house out of and how much you're willing to spend. The problem I am running in to is that I don't know how to get out of this spiral. I can't just turn down work because then I wouldn't have any. I really don't want to go work for another company -- and even if I did, I'd probably still be stuck using something I don't enjoy. I'm hoping someone has "been there" before and might have some good ideas on how to get out of this situation. Thanks!

  • What are some techniques I can use to refactor Object Oriented code into Functional code?

    - by tieTYT
    I've spent about 20-40 hours developing part of a game using JavaScript and HTML5 canvas. When I started I had no idea what I was doing. So it started as a proof of concept and is coming along nicely now, but it has no automated tests. The game is starting to become complex enough that it could benefit from some automated testing, but it seems tough to do because the code depends on mutating global state. I'd like to refactor the whole thing using Underscore.js, a functional programming library for JavaScript. Part of me thinks I should just start from scratch using a Functional Programming style and testing. But, I think refactoring the imperative code into declarative code might be a better learning experience and a safer way to get to my current state of functionality. Problem is, I know what I want my code to look like in the end, but I don't know how to turn my current code into it. I'm hoping some people here could give me some tips a la the Refactoring book and Working Effectively With Legacy Code. For example, as a first step I'm thinking about "banning" global state. Take every function that uses a global variable and pass it in as a parameter instead. Next step may be to "ban" mutation, and to always return a new object. Any advice would be appreciated. I've never taken OO code and refactored it into Functional code before.

  • User Switching in XFCE 12.04 with LightDM and dumping unneeccesary Gnome libs

    - by user111120
    I'm an elder non-techie Mac-to-Linux convert trying to play the linux tech game by ear, so please be gentle! :) I am running XFCE Ubuntu 12.04 totally on a 8-gig flash drive and it's fantastic. I am starting to run into potential space issues (down to 1.0 gig free from 1.9 gigs since being installed last summer), most likely because of growing Thunderbird mail files, and this prompted my question. I just installed lightDM on my system because I want the ability to switch users in XFCE if I follow instructions on another blog. They advised using LightDM instead of GDM because LightDM doesn't download Gnome libraries. That's great since I need the space, but my question is how can I tell whether I don't already have Gnome libraries installed from other updates and such? And can I minimize having any Gnome libraries? The method for me to switch users entails creating a "fast-user-switch" file in /usr/local/bin; is there any easier way? One last thing so I din't have topen another needless thread; while experimenting I somehow lost the share folder in one of my accounts. Is there any way to get a share folder back? Thanks for any tips! Jim in NYC

  • Blocking popups and ads

    - by user74364
    I'm having a fight with ads, popups and tracking cookies. But i'm having some issues. Software used: Chromium 18.0.1025.168 Extensions used: Adblock Plus (Beta)1.2 AdBlock+ Element Hiding Helper1.1.9.18 Better Pop Up Blocker2.1.6 Ghostery3.0.0 With this configuration, i'm always getting this error: Warning: This extension failed to modify a network request because the modification conflicted with another extension. I know if i disable "better popup", this goes away. It's perfectly normal, due to those extensions trying to block the same things. Problem is, i can't live without all of them! Can anyone advise me about some good configuration? Can't live without adblock plus, because i hate ads. Betterpopup blocker is essential too (believe me, chrome doesn't block a lot of popups, and i have a website or 2 that can proove that.) And ghostery is a must... i can't bare the idea of being tracked all the time by some companies. So i'm kinda lost here! everything is needed, but they conflict with each other. i mean, it has to exist a perfect combination out there, i know i'm not the only one hating the privacy issues nowadays! really thankful for any tips guys

  • Graphical Interface and Object Selection/Manipulation

    - by ToriArendt
    I have a project I want to try to implement, but I'm kind of stuck on how to get started. I know there are probably a lot of resources that I can look at, but I'm really just stuck on what to even search for and where to begin. Basically, I have a program written in Java that separates 3D coordinates from a 3D reconstructed model into different objects. I then want to be able to perform a logistic regression on these objects to determine if they are type A or type B. But first, I need to classify a training set of objects as type A or B by hand. I don't know ANYTHING about graphing or user interfaces in Java, so I have been plotting the coordinates of a given object in MATLAB so that I can visualize the object and assign it a type. Now, as I am trying to make this program more "user friendly" I want to create an interface in Java where I can simply graph all the coordinates of the objects from the entire 3D model (on the same graph). I then want to be able to click on the each object and assign it to be either of type A or type B. I hope this description makes sense and someone can point me in the direction of something that will help me. I'm sorry if some of this terminology is off; I'm a bit new to software development. P.S. If anyone also has some tips on implementing logistic regression in Java, I'm sure I'll need them down the road :).
