  • ipheth notification at login prompt

    - by spudwaffle
    On my command line only Ubuntu machine, the login prompt occasionally shows a warning: Ubuntu 12.04 LTS myserver tty1 myserver login: [833747.589882] ipheth: ipheth_rcvbulk_callback: urb status: -71 Nothing is obviously wrong with the system, and I can enter my username and password without issue. What does this message mean and should I be worried about it? Edit: I've found plugging in and then removing my iPhone from the computer causes this message. I'm still looking for what it means.

  • proper model for a multi site rails app

    - by JeffTaggarty
    Hi Guys, I am not sure if this is correct place to ask this question. My apologies if it is not. I need to create a web app where people will sign up, call it main-app.com, when they sign up my code will generate a usersite.my-app.com, they will login and only be able to manage their mini site. My question is, is it correct to model this out by creating a table for site, a table for user, users belong to site and site has many users. Then I should create a content table that belongs to user AND site? is that right? Thanks Jeff

  • Do you prefer building your interfaces in IB or programmatically? and why?

    - by LolaRun
    I've been using Xcode and building iPhone apps for two months, but I'm finding it really hard to grasp good application design. I always face problems—like you can't put your tabbarcontroller in another custom viewcontroller, for example—that 'sometimes', of course, would work if you did the creation of the views/viewcontrollers programmatically. So I don't know if I should start writing the creation of my objects or use Interface Builder. What are your experiences?

  • Adobe Air apps on the Mac App Store?

    - by coneybeare
    Before you chastise me for asking this, I have an Adobe Air app that has a lot of investment in it, and if there is a way to utilize the existing code-base in any way, it is worth considering. I have heard news reports in passing about Adobe creating some kind of tool to allow flash or air apps to be ported to native objective-c code, but the information found in google is mostly commentary on the one-time Apple blockade. My question(s) is/are this: Is it even possible, at any level, to use an existing Air app to create a Mac Store app? If possible, what are the resources I can use to accomplish this?

  • Apple reveals the iPhone 4.0 multitasking

    Finally Apple decided to add multitasking to the iPhone to compete with all the new devices coming up and existing. At an Apple press event, CEO Steve Jobs announces multitasking support in the newest iPhone operating system. Users will finally be able to switch back and forth between applications like Pandora and Skype without having to shut down the app entirely to enter a new one. Their excuse to not bringing multitasking until now is they were waiting to make multitasking right. New features...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.

  • Rotating Sprite around Y-Axis (2D)

    - by Bruce Collie
    I'm going to be creating a game soon, and part of it involves spinning sprites. The sprites will be spinning around the Y-Axis (imagine a spinning plate on top of a stick, where the stick stands up vertically. The main way I've thought of is to have a series of sprites for various rotation values that I blur between as the 'plate' rotates (the sprite is more complex than a plate, though). The game will be for iPhone, but I'm open to using any 2D gave development library for it.

  • Do I have to remove my app from app store? (Copyright infringement)

    - by Smiden
    I just got an copyright infringement notice that says my app infringes on the usage policies of the services my app uses. However, this mail does not come directly from the company that runs the website I pull information from. The mail comes from a company that has some paid apps in the same category on the app store (mine is free), so they obviously want me gone. My question is, can I just ignore this mail until I hear directly from the company that runs the website? Judging from their (the company that contacted me) website, they have no connection what so ever to the company that I fetch information from.

  • Walkthrough/guide building aplication server for multi tenant web app [on hold]

    - by Khalid Adisendjaja
    The web app will detect a subdomain such as tenant1.app.com, tenant2.app.com, etc to identify tenant environment, each tenant environment will have a different database credential (port,db name,etc) but still connecting to the same database server. Each tenant should use app.com for their main domain, using their own domain is prohibitted. Each tenant will have their own rest api endpoint such as tenant1.app.com/api/v1/xxxx, tenant2.app.com/api/v1/xxxx, tenant3.app.com/api/v1/xxxx I've come to a simple solution by setting a wildcard subdomain (*.app.com) on webserver Apache/Nginx vhost configuration file. I have googled so many concept for building a multi-tenant app server but still don't understand how to really done it, what is the right way to do it and what is actually required to do this task. So I've come to this questions, Do I need a proxy server, dns masking, etc.. How to monitor each tenants activity What about server performance, load balancing, and scalability How to setup ssl certificate for each tenant what about application cache for each tenant Is it reliable to use the setup for production etc ... I have a very litte experience on server infrastructure, so I'm looking for a DIY walkthrough, step by step guide, or sophisticate solution ready to implemented for production

  • iPhone application build fails with "dyld: Library not loaded: /System/[...]" error? Why?

    - by Andrew J. Brehm
    For my own reasons and not for the app store I am referencing the Apple private framework Apple80211 in an iPhone app. I got the framework from an earlier version of the iPhone SDK. I added the "existing framework", verified that that absolute path to the framework is /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.0.sdk/System/Library/PrivateFrameworks/Apple80211.framework and tried to build the app. But the build (to device) fails with the error dyld: Library not loaded: /System/Library/PrivateFrameworks/Apple80211.framework/Apple80211 Referenced from: /var/mobile/Applications/3691587D-87AF-44EA-A505-F73D17F39B3B/iWire2.app/iWire2 Reason: image not found I cannot figure out why Xcode would look for the library in a /System path (instead of using the path given in the frameworks list) or how to change that behaviour. I tried the tricks I found here and elsewhere for similar (and identical) sitiations: Delete the myusername.* files in the xcodeproj bundle Delete the build directory Clean all targets Start new project Result is always the same. How can I add this (or a) framework to an iPhone project AND get Xcode to at least look at the library located where I point to rather than a location in /System?

  • Christian Radio Locator iPhone app

    - by Tim Hibbard
    For the last three months or so I've been working on an iPhone (and iPad) app in my spare time. It all started when I took the kids to Minneapolis and had a hard time finding radio stations to listen to on the trip. I looked in the App Store for an app that would use my GPS to show me Christian radio stations nearby, but there wasn't one. So I decided to build my own. Using public information from the FCC and a few other sources, I built a database in Google docs that contains the frequency for all Christian radio stations, where the tower is located and how far the tower can reach. I also included any streaming audio information and other contact information like Facebook or Twitter that I could find. Google spreadsheets publish in JSON format (yes, really) and Xcode can automatically deserialize JSON into a properly formatted entity. This is one area that Xcode is far superior to C#. In a just a few lines of code, I can have a list of in-memory strongly typed objects from a web-based JSON feed. To accomplish the same thing natively in .NET would be much more work and wouldn't feel nearly as clean when it was said and done. The snazzy icon shown above was built by my very talented wife. She hasn't yet provided any feedback on the app's user interface, which is why it is so plain and boring. I used a navigation view controller and EGO pull to refresh table view to construct the main window. Pulling down to refresh initiates a GPS lookup, which queries the database for radio stations in range (yes, you can pass parameters to Google spreadsheets and get a subset back in JSON). Pulling up on the table extends the range of the search and includes stations that may not be close enough to get clear audio. This feature is not that intuitive and the next version contains an update to that functionality. Tapping a cell will show a detail view that displays additional information about the station. The user can click to view the station on a map, click to listen to an online stream (if available) or click to see the station's Facebook or Twitter pages. Swiping back and forth on the table changes the information that is displayed on the right hand side of the table cell. It scrolls through the city where the tower is located, how far the phone is from the tower, the range of the tower and in the next version a signal strength indicator. This was pretty easy to implement once I figured out how to assign the gesture recognizer delegate.  Tapping and holding on a cell will jump the user to the map view screen. Which is pretty cool, but very hard for even a power user to discover. To tackle the issue of discoverability, the next version has a series of instructions displayed at the bottom of the screen to show the user the various shortcuts. Once the user has performed the swipes and long holds, the instructions disappear. I've learned a lot developing this app. Spending over a decade exclusively in .NET made the learning curve a bit steep, but once I learned the structure and syntax of Objective-C, I've learned to appreciate the power and simplicity of it. Here are a few screenshots. I would really appreciate any feedback and especially iTunes reviews. Technically it is open source and a smart googler could probably find it. I just haven't promoted it as open source.     Cross posted from timhibbard.com

  • App Stores&ndash;In All Things, Its Quality Over Quantity

    - by D'Arcy Lussier
    Everybody has an opinion about Windows 8. People love it, people hate it, people are meh about it, people are apparently buying it from Microsoft stores in NYC as if it was water before a natural disaster…if there’s one thing that Microsoft product launches do well, its the ability to bring out strong emotional responses. Over at eweek.com, Don Reisinger wrote about 5 good and bad things about Windows 8. Yes, another opinion piece on WIndows 8. I figured since this one had good and bad it might be worthwhile to read. I then came across #10 on his list, and figured “What the hell…might as well post a bit of a rant on Windows 8 myself!” Here’s #10: 10. Bad: Too few apps Unfortunately, Microsoft wasn’t able to get too many developers to start producing applications for its Windows 8 Store. Microsoft hasn’t yet released official numbers, but some have said that the marketplace has less than 8,000 programs. Considering Apple’s App Store has 100 times that, it’s about time Microsoft starts leaning on developers to get more programs into its store. Believe me, Microsoft *has* been leaning on developers to get apps into the store. I’ve been asked at least 5 or 6 times from 5 or 6 different friends at Microsoft about whether I was going to write a Windows 8 app. I think Microsoft felt they had to try and address the number of apps available in their marketplace, since some people (like Don) would draw comparisons to the number of apps in the Apple marketplace. I feel for Microsoft in this, since the number of apps in a marketplace are an empty stat. Quality of Quantity I have an iPad that my family (wife, 10yo daughter, 3yo daughter) use. We all have our own apps installed on it. In addition, my wife has an iPhone 4S that she also installs apps on. As someone who gets asked by his kids often whether they can buy/download an app, the vast majority of the vast catalogue of iOS marketplace apps are crap! Do you realize how many “free” games are out there, only to really be not-free because you have to purchase in-game content to make the game actually playable? And how about searching – with such a vast array of apps and such high numbers of craptastic ones, trying to find something is incredibly difficult and can be frustrating. I would rather see that Microsoft has 8000 high quality apps in their store at launch, instead of 800000 that were mostly junk. Too Few Apps?! And seriously, 8000 is not a small number. How many iOS apps have I actually bought between the iPad and iPhone? I’ll be generous and say 30…heck, let’s round it up to 40. It’s not like I have 10,000 apps installed on my iPad, nor will that ever happen! So if people have, at the *launch* of a new platform ecosystem, EIGHT THOUSAND apps to choose from, I don’t see that as a fail at all! It should be noted that most of the most common apps (Netflix, Skype, etc.) are available for Windows 8 at launch – I guess I’ll have to wait a few weeks for My Pony Ranch and all its clones to start showing up; pity. Let’s Check Back in a Year So look, let’s check back in a year’s time and see what the app store looks like. My hope is that Microsoft doesn’t continue to push quantity over quality. Even knowing the optics that # of apps in the store carries and the pressure to catch Apple and Android marketplaces, I hope Microsoft avoids the scenario where there’s a good percentage of apps in the Windows Store that are utter rubbish and finding the gems will be cumbersome. But if that happens, we can thank guys like Dan who raised the false issue of app count at the launch for it.

  • Process Is The New App by Leon Smiers

    - by JuergenKress
    Process-on-the-Fly #2 - Process is the New App The next generation of business process management and business rules management tools is so powerful that it actually can be seen as the successor to custom-built applications. Being able to define detailed process, flows, decision trees and business helps on both the business and IT side to create powerful, differentiating solutions that would have required extensive custom coding in the past. Now much of the definition can be done ‘on the fly,’ using visual models and (semi) natural language in the nearest proximity to the business. Over the years, ERP systems have been customized to enter organization-specific functionality into the ERP application. This leads to better support for the business, but at the same time involves higher costs for maintenance, high dependency on the personnel involved in this customization, long timelines to deliver change to the system and increased risk involved in upgrading the ERP system. However, the best of both worlds can be created by bringing back the functionality to out-of-the-box usage of the ERP system and at the same time introducing change and flexibility by means of externalized 'Process Apps' in direct connection with the ERP system. The ERP system (or legacy bespoke system, for that matter) is used as originally intended and designed, resulting in more predictable behavior of the system related to usage and performance, and clearly can be maintained in a more standardized and cost-effective way. The Prrocess App externalizes the needed functionality into a highly customizable application outside the ERP for which it is supported by rules engines, task inboxes and can be delivered to different channels. The reasons for needing Process Apps may include the following: The ERP system just doesn't deliver this functionality in a specific industry; the volatility of changing certain functionality is high; or an umbrella type of functionality across (ERP) silos is needed. An example of bringing all this together is around the hiring process for a new employee at a university. Oracle PeopleSoft HCM could be used as the HR system to store all employee details. In the hiring process, an authorization scheme is involved for getting the approval to create a contract for the employee-to-be. In the university world, this authorization scheme is complex and involves faculties/colleges (with different organizational structures) and cross-faculty organizational structures. Including such an authorization scheme into PeopleSoft would require a lot of customization. By adding a handle inside PeopleSoft towards an externalized authorization Process App, the execution of the authorization of the employee is done outside the ERP: in a tool that is aimed to deliver approval schemes via a worklist-type of application. The Process App here works as an add-on to the PeopleSoft system, but can also be extended to support the full lifecycle of the end-to-end hiring process with the possibility to involve multiple applications. The actual core functionality is kept in the supporting ERP systems, while at the same time the Process App acts as an umbrella function to control the end-to-end flow and give insight into the efficiency of the end-to-end process.

  • The binary you uploaded was invalid. A pre-release beta version of the SDK was used to build the app

    - by Nick
    I am having a problem submitting my new app to the appstore. ItunesConnect gives me the error: The binary you uploaded was invalid. A pre-release beta version of the SDK was used to build the application. I haven't changed anything, I can compile to a ad-hoc certificate and that works fine. I uploaded another app yesterday and that worked fine too. All the targets and project info is set to compile to the base SDK iPhone OS 3.0. I even upgraded to the latest SDK but same result. Any ideas?

  • How to set selected segment index in UISegmentedControl? (iPhone SDK)

    - by seanny94
    Hello all! I'm trying to avoid an app crash here... I have a button that will remove a segment from a UISegmentedControl. If that button is pressed and the user has the segment to be removed selected, the segment will remove and no selection will be highlighted. However, when another button is pushed that does an action that retrieves the selectedSegmentIndex, the app crashes. In short: Is there any way to force the selection of a segment in a UISegmentedControl? edit it seems as though the UISegmentedControl is returning a selectedSegmentIndex of -1 when no segment is selected... let's see what I can do from here.
