  • Android/Java learning resources for an experienced Objective C programmer?

    - by hotpaw2
    What resources are available for an experienced Objective C programmer to quickly and efficiently learn and get up to speed with Java, the Android SDK API's and Eclipse IDE? There seems to be at least one book and several web sites for experienced Java programmers who want to learn native Objective C programming, iOS UIKit and Xcode, but who don't want to waste time with a lot of basic programming concepts that an experienced Java programmer usually already knows. What are the available advanced educational materials for the inverse direction?

  • Developing Good Contacts

    There are millions of was you can develop good networking contacts, but you must be open to meeting new people. In the information technology industry, everyone is a potential client. So any place you can meet people is a good place to develop good networking contacts. Here are a few examples Online Discussion Forums – Online forums are a great place to show your knowledge of a subject and allow you to meet people that share your same interests Blog Networks – Allowing others to read your thoughts and comment on them. In addition, you can so the same on other blogs with in the network. Networking Sites – Networking sites are a great way to find new contacts based on your current contacts because you can share common friends, and possibly common interests Volunteering – Volunteering is a great way to meet new contacts, and you can help others at the same time Civic Organizations – Participating in organizations or clubs like the Lions Club, Rotary Club, and religious affiliated organizations because you can meet people of all walks of life, and can share and contribute ideas for common goals Chamber of Commerce – This is another great way to meet contacts especially if you are interested in starting your own business. The chamber is a great way to meet other business oriented people who are always looking to collaborate and improve their business.

  • Is it worth moving from Microsoft tech to Linux, NodeJS & other open source frameworks to save money for a start-up?

    - by dormisher
    I am currently getting involved in a startup, I am the only developer involved at the moment, and the other guys are leaving all the tech decisions up to me at the moment. For my day job I work at a software house that uses Microsoft tech on a day to day basis, we utilise .NET, SqlServer, Windows Server etc. However, I realise that as a startup we need to keep costs down, and after having a brief look at the cost of hosting for Windows I was shocked to see some of the prices for a dedicated server. The cheapest I found was £100 a month. Also if the business needs to scale in the future and we end up needing multiple servers, we could end up shelling out £10's of £000's a year in SQL Server / Windows Server licenses etc. I then had a quick look at the price of Linux hosting for a dedicated server and saw the price was waaaaaay lower than windows hosting. One place was offering a machine with 2 cores for less than £20 a month. This got me thinking maybe the way to go is open source on Linux. As I write a lot of Javascript at work (I'm working on a single page backbone app at the moment), I thought maybe NodeJS and a web framework like Express would be cool to use. I then thought that instead of using SQL why not use an open source NoSQL database like MongoDB, which has great support on NodeJS? My only concern is that some of the work the application is going to do is going to be dynamically building images and various other image related stuff, i.e. stuff that is quite CPU heavy - so I'm thinking of maybe writing anything CPU heavy in C++ and consuming it as a module in Node. That's the background - but basically is Linux a good match for: Hosting a NodeJS/Express site? Compiling C++ node modules? Using a NoSQL DB like MongoDB? And is it a good idea to move to these unfamiliar technologies to save money?

  • BUILD 2013 Session&ndash;Alive With Activity

    - by Tim Murphy
    Originally posted on: http://geekswithblogs.net/tmurphy/archive/2013/06/27/build-2013-sessionndashalive-with-activity.aspx Live tiles are what really add a ton of value to both Windows 8 and Windows Phone.  As a developer it is important that you leverage this capability in order to make your apps more informative and give your users a reason to keep opening the app to find out details hinted at by tile updates. In this session Kraig Brockschmidt cover a wide array of dos and don’ts for implementing live tiles.  I was actually worried whether I would get much out of this session when Kraig started it off with the fact that his background is in HTML5 based apps which I have little interest in, but the subject almost didn’t come up during his talk.  It focused on things like making sure you have all the right size graphics and implementing all of the tile event handlers.  The session went on to discuss the message format for push notification and implementing lock screen notification and badges. As with the other day 1 sessions it was like drinking from a fire hose, but it was good stuff.  Check it out when they post it on Channel 9. del.icio.us Tags: BUILD 2013,Live Tiles,Windows 8.1

  • Stuff to read up on pricing applications

    - by tux91
    I'm about to release an app and I have no idea what would be the ideal pricing point. I'm not sure how pricing high and selling few copies will compare in revenue to pricing low and selling lots of copies in my case. Can somebody point me to books/articles/blog posts/etc that elaborate on the subject, preferably taking into account stuff like competition, number of features, being the first one to the market, research if this kind of app is even needed, etc?

  • Using pkexec policy to run out of /opt/

    - by liberavia
    I still try to make it possible to run my app with root priveleges. Therefore I created two policies to run the application via pkexec (one for /usr/bin and one for /opt/extras... ) and added them to the setup.py: data_files=[('/usr/share/polkit-1/actions', ['data/com.ubuntu.pkexec.armorforge.policy']), ('/usr/share/polkit-1/actions', ['data/com.ubuntu.extras.pkexec.armorforge.policy']), ('/usr/bin/', ['data/armorforge-pkexec'])] ) additionally I added a startscript which uses pkexec for starting the application. It distinguishes between the two places and is used in the Exec-Statement of the desktopfile: #!/bin/sh if [ -f /opt/extras.ubuntu.com/armorforge/bin/armorforge ]; then pkexec "/opt/extras.ubuntu.com/armorforge/bin/armorforge" "$@" else pkexec `which armorforge` "$@" fi If I simply do a quickly package everything will work right. But if I package with extras option: quickly package --extras the Exec-statement will be exchanged. Even if I try to simulate the pkexec call via armorforge-pkexec It will aks for a password and then returns this: andre@andre-desktop:~/Entwicklung/Ubuntu/armorforge$ armorforge-pkexec (armorforge:10108): GLib-GIO-ERROR **: Settings schema 'org.gnome.desktop.interface' is not installed Trace/breakpoint trap (core dumped) So ok, I could not trick the opt-thing. How can I make sure, that my Application will run with root priveleges out of opt. I copied the way of using pkexec from synaptic. My application is for communicating with apparmor which currently has no dbus interface. Else I need to write into /etc/apparmor.d-folder. How should I deal with the opt-build which, as far as I understand, is required to submit my application to the ubuntu software center. Thanks for any hints and/or links :-)

  • How can I install the Play! framework using typesafe-stack? [migrated]

    - by lhk
    I'd like to create a new project with the Play! framework. My system is Mint 12 64bit. Since the newest version of Play! is already bundled with the typesafe-stack, I thought installation would be easy. I added the typesafe repo, then I apt-get updated and apt-get installed typesafe-stack with the command g8 typesafehub/play-scala. I successfully created a new project in my home folder. Now the problems begin: I don't know how to access Play! with this installation. After creating the project, I tried to convert it into an Eclipse project, it but there's no play command available in the terminal. How can I get a "standard" Play! installation on Linux? What happens to the tools bundled in the typesafe stack - Where do they go?

  • How should an undergraduate programmer organize his time learning the maximum possible?

    - by nischayn22
    I started programming lately(pre-final year of a CS degree) and now feel like there's a sea of uncovered treasure for me out there. So, I decided to cover as much as is possible before I look out for a job after graduation. So, I started to read books (The C++ Programming Language, Introduction to Algorithms, Cracking the Coding Interview, Programming Pearls,etc ) participate in StackExchange sites, solving problems (InterviewStreet and ProjectEuler), coding for open source, chatting to fellow programmers/mentors and try to learn more and more. Good,then what's the problem?? The problem is I am trying to do many things, but I am doubtful that I am still utilizing my time properly. I am reading many books and sometimes I just leave a book halfway (jumping from one book to another), sometimes I spend way too much time on chatting and also in getting lost somewhere in the huge internet world, and lastly the wasteful burden of attending classes (I don't think my teachers know good enough or I prefer learning on my own) May be some of you had similar situation. How did you organize your time? Or what do you think is the best way to organize it for an undergraduate? Also what mistakes am I making that you can warn me of

  • Which programming language should I choose I want to build this website ...? [closed]

    - by Goma
    Assuming that I will start with just phot sharing website. Every user can add comments to any photo. After that the site will contain news (general news), the admin can add any news and the moderators as well while the users can also add comments on this news. The website will aslo provide photos uploader, so every user will have up to 20 MB ti upload any photos they want. Other users can see these photos or can not depending on the option that the main user chose(if he wants to publish his photos or not). The site should have a small type of forum which provide the ability for admin to ad categories and for user to add topics and replies for each topic in these categoris. These are the things that I can think of now, but the website will add other features as well and services later on. Can you tell me now which programming language can help me to do all that? I need a programming language that provdies the follwing: 1- speed load for pages of the site. 2- easy to add more functions quickly and easy to edit code for any reason. 3- Secure 4- fast in displaying infromation from database.

  • Vanilla forum personal journal tool

    - by user16648
    I am developing a forum for a research project, i am using Vanilla forum (though i am not tied to this yet). Another feature of this site will be a personal journal/diary/blog. Only the user and administrators will have access to the journal. The journal does not need any advanced features. Does anybody have any suggestions on software/script that could easily be integrated with Vanilla forum for this purpose? My first thought was using Wordpress but it is a bit to complex to adminstrate as the site is meant to be simple. And i dont really see how it can be intregrated easily the way i want it.

  • How can I install an old version of libc on 12.04 and is it safe to do so?

    - by mathematician1975
    I am building an application on 12.04 and I need to run it on an embedded device. The device has libc-2.8.90.so on it and my dev machine has libc-2.15.so on it. I would like to install libc-2.8.90 onto my dev machine and attempt to link it to my application. I have searched at the Ubuntu software centre for libc-2.8.90 but I cannot find anything resembling it. Is there a way to install this on my machine from command line?? Also will my system be safe having 2 installed versions of libc at the same time? Can it lead to any instability?

  • Hopping/Tumbling Windows Could Introduce Latency.

    This is a pre-article to one I am going to be writing on adjusting an event’s time and duration to satisfy business process requirements but it is one that I think is really useful when understanding the way that Hopping/Tumbling windows work within StreamInsight.  A Tumbling window is just a special shortcut version of  a Hopping window where the width of the window is equal to the size of the hop Here is the simplest and often used definition for a Hopping Window.  You can find them all here public static CepWindowStream<CepWindow<TPayload>> HoppingWindow<TPayload>(     this CepStream<TPayload> source,     TimeSpan windowSize,     TimeSpan hopSize,     WindowInputPolicy inputPolicy,     HoppingWindowOutputPolicy outputPolicy )   And here is the definition for a Tumbling Window public static CepWindowStream<CepWindow<TPayload>> TumblingWindow<TPayload>(     this CepStream<TPayload> source,     TimeSpan windowSize,     WindowInputPolicy inputPolicy,     HoppingWindowOutputPolicy outputPolicy )   These methods allow you to group events into windows of a temporal size.  It is a really useful and simple feature in StreamInsight.  One of the downsides though is that the windows cannot be flushed until an event in a following window occurs.  This means that you will potentially never see some events or see them with a delay.  Let me explain. Remember that a stream is a potentially unbounded sequence of events. Events in StreamInsight are given a StartTime.  It is this StartTime that is used to calculate into which temporal window an event falls.  It is best practice to assign a timestamp from the source system and not one from the system clock on the processing server.  StreamInsight cannot know when a window is over.  It cannot tell whether you have received all events in the window or whether some events have been delayed which means that StreamInsight cannot flush the stream for you.   Imagine you have events with the following Timestamps 12:10:10 PM 12:10:20 PM 12:10:35 PM 12:10:45 PM 11:59:59 PM And imagine that you have defined a 1 minute Tumbling Window over this stream using the following syntax var HoppingStream = from shift in inputStream.TumblingWindow(TimeSpan.FromMinutes(1),HoppingWindowOutputPolicy.ClipToWindowEnd) select new WindowCountPayload { CountInWindow = (Int32)shift.Count() };   The events between 12:10:10 PM and 12:10:45 PM will not be seen until the event at 11:59:59 PM arrives.  This could be a real problem if you need to react to windows promptly This can always be worked around by using a different design pattern but a lot of the examples I see assume there is a constant, very frequent stream of events resulting in windows always being flushed. Further examples of using windowing in StreamInsight can be found here

  • Web app to take screen shot of website and annotate?

    - by Anagio
    Does anyone know of a website that will take a full screen shot of another website and let users write notes over it then send that annotated photo by email or private link? Basically looking for quicker way to write notes on a site other than taking a screen shot my self and putting it into photoshop. Just an update, I don't need any browser extensions which I already have and do the same. I'm looking for a website app which does this to give to a client.

  • Abandoment to blame for the last JavaScript file not always being loaded?

    - by Larsenal
    I have a code snippet for an app that users are loading as a 3rd party script on their site. The general sequence is as follows: Site loads http://www.example.com/foo.js foo.js does stuff 1 to 2 seconds later, foo.js loads bar.js Now in a perfect world, I'd want to see matching counts for the calls to foo.js and bar.js. However, bar.js loads only about 94% of the time. I'm wondering how much of this discrepancy might be attributable to site abandonment given the fact that bar.js is delayed by 1 or 2 seconds. I posted here instead of StackOverflow since I think it's more a question about what would be typical time on page when users abandon the page.

  • Do you use to third party companies to review your company's code?

    - by CodeToGlory
    I am looking to get the following - Basic code review to make sure they follow the guidelines imposed. Security code analysis to make sure there are no loopholes. No performance bottlenecks by doing a load test etc. We have lot of code coming in from third parties and is becoming laborious to manage code reviews and hence looking to see if others employ such practices. I understand that it may be a concern for some and would raise the question "Well, who is going to make sure the agency is doing their job right?" But basically I am just looking for a third party who can hold all vendor code to the same standards.

  • High paid non-finance programming roles? [closed]

    - by Ian
    Besides finance (front-office/high frequency trading) developer roles, are there any other very well paid programming roles, specifically for C++ or Java? One particular industry I would find interesting is the energy industry? However, I completed an internship for one of the massive energy companies and their "IT department" was nothing more than Microsoft Access- they outsourced all the technical work to IBM and Accenture. EDIT: USD 110k+ Defense would sounds great except the fact I am not a US citizen :)

  • What "version naming convention" do you use?

    - by rjstelling
    Are different version naming conventions suited to different projects? What do you use and why? Personally, I prefer a build number in hexadecimal (e.g 11BCF), this should be incremented very regularly. And then for customers a simple 3 digit version number, i.e. 1.1.3. 1.2.3 (11BCF) <- Build number, should correspond with a revision in source control ^ ^ ^ | | | | | +--- Minor bugs, spelling mistakes, etc. | +----- Minor features, major bug fixes, etc. +------- Major version, UX changes, file format changes, etc.

  • I'm the .1x programmer at my company. How can I best contribute?

    - by invaliduser
    I work at a newly-minted startup of five people. We have a Ph. D in machine learning, a former member of the RSpec core team, and the guy who compiles the Git binary for OS X. That's just the employees; the founder has a Ph. D and was CTO for a multi-billion-dollar corporation before leaving to start a (successful) startup, and has now left that to start this one. We also might get a guy with a Ph. D in math. Aaaaaaaaand then there's me, college-dropout intern. I think I'm pretty smart and I'm reading non-stop, but the delta of experience, skill, and knowledge between me and my co-workers is just breathtaking. So put yourself in their shoes: you've got a bright young intern who has a lot to learn but is at least energetic. What would be annoying? What use would you hope to get out of him in the here and now? What would be pleasantly surprising if it happened?

  • Ad networks that will serve via HTTPS?

    - by Dogweather
    I've built a website with 160K page views per month that serves every page over HTTPS. The recent FireSheep news will probably increase the adoption of "HTTPS everywhere" but it's been very hard to find ad networks and affiliates that will serve their content via HTTPS. I don't want to use these because I don't want my visitors to get "broken security" notification from their browsers (and of course, relevant ads would be a leak of private information). I'm tired of spending a ton of time signing up with ad networks and affiliates only to find out down the road that they don't support HTTPS (e.g. AdSense). Can anyone suggest any options or provide a pointer to a list of these somewhere?

  • Expected salary for software engineer? Am I under or over paid? [closed]

    - by Asdasd Asdasd
    I work for a reasonably large tech company in Boston, MA. My company has about 1.2 billion in revenue and around 3500 employees. I have 6 years of industry experience and my current pay package is as follows: Base salary: 97,000 bonus: 10,000/year (everyone always gets 100% of this... i don't know why they bother call it bonus) RSU stock: 8000/year at present day valuation. My vesting schedule covers me for the next 5 years. that brings my total pay to ~ 115,000/year Given that, would folks say I am under/average/over paid? I read so much about how engineers at google and facebook are making ridiculous sums of money (almost 200k with bonuses included) and it makes me question my pay package. thanks

  • Bluetooth broadcasting realtime - is it possible

    - by user69961
    Is it possible to broadcast data via bluetooth to one ore more connected devices? I mean that each phone will be master and slave at the same time and each phone will broadcast data that should be received by all other phones. Or is the only possibility to use a "client-server"-like topology; one phone acts as a server and listens to all clients and then sends data from each client to the rest of clients in the network? Which variant should be more effective? If broadcasting is possible then the same implementation can be used for all devices and if one device will die communication between rest of network can continue. And also will there be enough to send one message per device - not message from each device to server and then back to all devices. Am I right?

  • Making diff output more readable

    - by mgunes
    I'm looking for a tool that will take diff / debdiff output (and more specifically, the output of this script) and display the result of the comparison in a highly readable, graphical way. Any pointers would be appreciated. Ideally, it would be the GTK+, FOSS equivalent of MDR. Meld, Diffuse and similar software are not fit for this purpose, since they're intended to work standalone, and don't take input from stdin.

  • Should I expect my peers to read or practice on a regular basis? [closed]

    - by Joshua Smith
    I've been debating asking this question for some time. Based several of the comments I read in this question I decided I had to ask. This feels like I'm stating the obvious, but I believe that regular reading (of books, blogs, StackOverflow, whatever) and/or practice are required just to stay current (let alone excel) in whichever stack you use to pay the bills, not to mention playing with things outside your comfort zone to learn new ways of doing things. Yet, I virtually never see this from many of my peers. Even when I go out of my way to point out useful (and almost always free) learning material, I quite often get a sense of total apathy from those I'm speaking to. I'd even go so far as to say that if someone doesn't try to improve (or at least stay current), they'll atrophy as technology advances and actually become less useful to the company. I don't expect people to spend hours a day studying or practicing. I have two young kids and hours of practice simply aren't feasible. Still, I find some time; perhaps on the train, at lunch, in bed for a few minutes, whatever. I'm willing to believe this is arrogance or naivete on my part, but I'd like to hear what the community has to say. So here's my question: Should I expect (and encourage) the same from my peers, or just keep my mouth shut and do my own thing?

    I've been extoling the Rules of Holes, hoping to give you both courage to get out of your Hole, and solace for having allowed yourself to get in a Hole in the first place. How about the others, the folks that see that you are up to your neck, the folks that could guide you out, the folks that are secretly glad that it is you down in the Hole instead of them. So this brings us to Rules of Holes #7: When you are in a hole, some will look down on you. Only a few will offer their hand, and of those,...(read more)
