  • Mobile Application development - get hands on at UKOUG

    - by Grant Ronald
    Development of mobile solutions is one of the hottest topics in the IT market at the moment.  Forbes predicts that mobile application development with outstrip native PC development by 4-1 by 2015.  I'm therefor delighted to announce that the UKOUG and Oracle have synch'd up to provide a rolling 3 day hands-on Mobile development lab at the UKOUG conference this year. We're setting up a lab of 10 Mac machines in which you will be able to develop iOS on-device applications.  And the great thing is, if you want to develop for Android, its the same lab as well!  Just think, write once and deploy to iOS or Android.  We know places will be limited so we are going to be putting in place a first-come-first-served booking system.  Walk-ups will be allowed only if places are free. This is your chance to start skilling up on the hottest development initiative in years.

  • exchange live feed with pre-recorded video for wireless internet camera to router

    - by nate
    I wasn't sure if this should be asked in Web Applications, or Network Engineering, or what... Long story short, I have a video camera with mic that is wirelessly connected to a router (NETGEAR R6200), which can then be viewed through an online service. I would like to be able to somehow exchange the live feed with a pre-recorded video, or image, preferably with pre-recorded sound (the sound of silence would be easiest). Can I place this inbetween the camera and the router, do I need to redirect the camera feed to my laptop first, and then push out the fake video/audio onto the router, without the service knowing the difference? Thanks much and I hope this is well understood!

  • take my Java skills to the next level

    - by waingram
    I am well versed in the basics of Java programming, although through most of my career I have been maintaining, upgrading, and debugging someone else's Java code. I am mainly familiar with basic servlet applications. I have a strong beginner knowledge of Maven and Ant. I have more web development with Ruby on Rails, but would like to bring my Java skills up to par with regard to web development. It seems the world of Java is so big, I have no idea what the next logical step is for me. Spring? JAX-RB? EJBs? What is the next logical step for someone like me and how would you recommend I approach it?

  • L'iPhone 5 : un écran plus grand et une nouvelle connectique, il arrivera le 21 septembre aux mêmes prix que l'iPhone 4S

    L'iPhone 5 a un écran plus grand et une nouvelle connectique propriétaire Il arrive le 21 septembre, aux mêmes prix que l'iPhone 4S Cinq. Apple a bien présenté ce soir son iPhone 5, avec un écran de 4 pouces (1136 x 640 en 16/9e). Comme prévue. Que les développeurs se rassurent, les applications conçues pour les anciens iPhones ne seront pas étirées mais se verront ajouter deux bandes noires.

  • How to permanently disable touchpad in 12.04?

    - by Andreas
    I'm looking for a way to permanently disable the touchpad in Ubuntu 12.04 (my computer is a Lenovo Thinkpad Edge on which it isn't possible to disable it in the BIOS). I tried the applications GPointingDeviceSettings and synaptiks 0.8.1 as well as the applets touchpad-indicator and Jupiter. None of these does the trick of disabling the touchpad permanently. Jupiter comes closest - it remembers that I have disabled the touchpad after restart - but when I login after the computer has been in suspend mode, the touchpad is enabled again. Can anyone help me in disabling the touchpad possibly at a lower level so it won't in any way be enabled unless I choose to enable it? I'm totally new to linux so a detailed explanation would be much appreciated ... The links, so far, doesn't address my question. I have no problem turning the touchpad off and making it stay off after reboot but when I login after the computer has been in an altered power mode it's on again. Isn't there a way to permanently disable a device like touchpad?

  • What are the industry metrics for average spend on dev hardware and software? [on hold]

    - by RationalGeek
    I'm trying to budget for my dev shop and compare our budget items to industry expectations. I'm hoping to find some information on what percentage of a dev's salary is generally spent on tooling, both hardware and software. Where can I find such information? If instead there is a source that looks at raw dollars that is useful, too. I can extrapolate what I need from that. NOTE: Your anecdotal evidence from your own job will not be very helpful. I'm looking for industry average statistics from a credible source. EDIT: I'm reluctant to even keep this question going based on the passionate negative responses of commenters, but I do think this is valuable information (assuming anyone will care to answer) so let me make one attempt to clarify why I'm looking for this information, and then leave it at that. I'm not sure why understanding and validating my motives is a necessary step to providing the information, but apparently that is the case, so I will do my best. Firstly, let me respond to the idea that us "management types" shouldn't use these types of metrics to evaluate budgets. I agree in part. Ideally, you should spend whatever is necessary on developers in order to keep them fully happy and productive. And this is true of all employees. However, companies operate in a world of limited resources, and every dollar spent in one area means a dollar not spent in another. So it is not enough to simply say "I need to spend $10,000 per developer next year" without having some way to justify that position. One way to help justify it is to compare yourself against the industry. If it is the case that on average a software shops spends 5% (making up that number) of their total development budget (salaries being the large portion of the other 95%, for arguments sake), and I'm only spending 3%, it helps in the justification process. So, it is not my intent to use this information to limit what I spend on developers, but rather to arm myself with the necessary justification to spend what I need to spend on developers to give them the best tools I can. I have been a developer for many years and I understand the need for proper tooling. Next, let's examine the idea that even considering the relationship between a spend on developer salaries and developer tooling is ludicrous and should be banned from budgetary thinking. As Jimmy Hoffa put it in their comment, it's like saying "I'm going to spend no more than 10% of median employee salary on light bulbs and coffee from now on.". Well, yes, it is like saying that, and from a budgeting perspective, this is a useful way to look at things. If you know that, on average, an employee consumes X dollars of coffee a year, then you can project a coffee budget based on that. And you can compare it to an industry metric to understand where you fall: do you spend more on coffee than other companies or less? Why might this be? If you are a coffee supply manager, that seems like a useful thought process. The same seems to hold true for developers. Now, on to the idea that I need to compare "apples to apples" and only look at other shops that are in the same place geographically, the same business, the same application architecture, and the same development frameworks. I guess if I could find such a statistic that said "a shop that is exactly identical to yours spends X on developer tooling" it would be wonderful. But there is plenty of value in an average statistic. Here's an analogy: let's say you are working on a household budget and need to decide how much to spend on groceries. Is it enough to know that the average consumer spends 15% on groceries and therefore decide that you will budget exactly 15%? No. You have to tweak your budget based on your individual needs and situation. But the generalized statistic does help in this evaluation. You can know if your budget is grossly off from what others are doing, and this can help you figure out why this is. So, I will concede the point that it would be better to find statistics that align to my shop, though I think any statistics I could find would be useful for what I'm doing. In that light, let's say that my shop is mostly focused on ASP.NET web applications. That doesn't map perfectly to reality because large enterprises have very heterogenous IT environments. But if I was going to pick one technology that is our focus that would be it. But, if you were to point me at some statistics that are related to a Linux shop doing embedded Java applications, I would still find it useful as a point of comparison. SUMMARY: Let me try to rephrase my question. I'm trying to find industry metrics on how much dev shops spend on developer tooling, both hardware and software. I don't so much care whether it is expressed as a percentage of total budget or as X dollars per dev or as Y percentage of salary. Any metric would be useful. If there are metrics that are specific to ASP.NET dev shops in the Northeast US, all the better, but I would be happy to find anything.

  • When it's more productive to build your own framework than using an existing one?

    - by Pierre 303
    I would like to know why you decided to build your own framework in your company. By framework, I don't mean few libraries you use often. I mean a specific way of building applications on top of it, with base classes, convention, etc. So why did you built your own framework? How could you justify that to the person that employs you. Have you measure the positive and negative impact of it? Regarding your experiences, did you notice that in some case a company framework produced real benefits, or on the other hand, increased costs of development (learning curve, debugging, maintenance, ...)?

  • Browser support for internal corporate tools

    - by adam
    We are on the verge of a conversion. For years, our company supported only IE for its internal (intranet) home-built tools. Since a few of our users are still on XP, which means IE only goes up to 8... a heavily JS / jQuery site wont even load! We have been in the process of converting to use Chrome instead, to make use of its javascript performance. But, it has now been suggested that we support all common browsers... internally for these tools. Which means more development time to scale-back some of these new applications, more time to test in all browsers, and we are already under staffed. Are there any good informational sites/posts out there, that already make this argument?

  • Where is a Web Development Career fueled by Passion?

    - by JMC Creative
    Quick Background Since learning basic html 5 years ago, I've become completely obsessed with the technology, the logic, and the thrill of solving problems involved with building websites. I am still stuck at a thoroughly non-programming type job, but would really like to move into the field of web programming/design. I have no educational background in the field (was trained as a fine artist and tutor), but in the past few years have progressed fully self-taught (and self-motivated) from html to css to php, mysql, jquery, and am now building rich web applications. The Question How can I prove to a company that even though I have no education, I have a passion to learn whatever is thrown my way? ...That essentially I would come at every issue with not only knowledge, but with a passionate desire to solve it, whether that means tackling a new language or debugging code for hours at a time? p.s. Sorry for the stupid title.

  • Useful design patterns for working with FragmentManger on Android

    - by antman8969
    When working with fragments, I have been using a class composed of static methods that define actions on fragments. For any given project, I might have a class called FragmentActions, which contains methods similar to the following: public static void showDeviceFragment(FragmentManager man){ String tag = AllDevicesFragment.getFragmentTag(); AllDevicesFragment fragment = (AllDevicesFragment)man.findFragmentByTag(tag); if(fragment == null){ fragment = new AllDevicesFragment(); } FragmentTransaction t = man.beginTransaction(); t.add(R.id.main_frame, fragment, tag); t.commit(); } I'll usually have one method per application screen. I do something like this when I work with small local databases (usually SQLite) so I applied it to fragments, which seem to have a similar workflow; I'm not married to it though. How have you organized your applications to interface with the Fragments API, and what (if any) design patterns do you think apply do this?

  • How can I make a case for "dependency management"?

    - by C. Ross
    I'm currently trying to make a case for adopting dependency management for builds (ala Maven, Ivy, NuGet) and creating an internal repository for shared modules, of which we have over a dozen enterprise wide. What are the primary selling points of this build technique? The ones I have so far: Eases the process of distributing and importing shared modules, especially version upgrades. Requires the dependencies of shared modules to be precisely documented. Removes shared modules from source control, speeding and simplifying checkouts/check ins (when you have applications with 20+ libraries this is a real factor). Allows more control or awareness of what third party libs are used in your organization. Are there any selling points that I'm missing? Are there any studies or articles giving improvement metrics?

I have never used a mac or macbook before so before I go purchase anything I would like to know what your thoughts are on this. Has anyone any experience with this?
