  • How to deal with the need to know multiple programming languages? When to stop learning new languages?

    - by Raphael
    I am a relatively young programmer. I am 23 and I have been programming professionally for about 5 years. As most programmers I started with C, learned some x86 assembly for fun and then I found C++ which turned out to be my greatest passion in the programming world. Programming with C and C++ forces you to learn platform specific APIs, libs and frameworks all of each requires constant study and experimentation. After some time I had to move on to Java and C# as the demand on my region is basically for these languages. With these languages I entered the world of web development and then I had to learn javascript. Developing for the .NET Framework was exciting at first but I constantly felt as I was getting tied up by Microsoft (and of course the .NET Framework was driving me away from Linux). For desktop development I could do pretty much everything I did with .NET using C++ with Qt but for web development I had to look for an alternative. Quickly I found Django and then I proceeded to learn Python so I could use Django. Nowadays I am learning iOS development with Objective-C. So far it was pretty much easy to learn all these languages (C++ trained me well) but I am worried that someday I won't be able to keep track of them all. Just to clarify. The only languages I learned cause I had to were C# and Java. All of the others I learned for fun, because I love programming and learning new things. Also I like to keep my skills sharp on desktop, web and mobile development. My question is: How do you keep track of multiple programming languages? (I mean, keep track of changes to these languages and keep your skills sharp) and: Is there such a thing as enough programming languages?

  • Mapping Your Customer Experience Journey

    - by Michael Hylton
    For those who attended today’s Oracle Customer Experience Summit keynote you heard from Brian Curran talk about the strategies and best practices to implement customer experience (CX) in your organization.  He spoke about how this evolving journey begins by understanding six steps to transform your business and put your customers front and center.  Here are those key six steps: What are the strategic business objectives in your company? What are your operational objectives and KPIs necessary to measure a CX project? Build an income statement and create “what if” scenarios and see how changes impact your business’ bottom line.  Explore what keeps you from getting to your own goals for your business. Define the business objectives and opportunities you want to meet? Understand the trends and accelerators in the market?  What factors are going on in the market affect that impact your business?  Social?  Mobile?  Cloud?  Just to name a few.  Many of these trends may signal a change in the way people think about your business. What approach will you take to solve these issues?  Understand who your customer is.  How do you need to adapt your business to build relevant, personalized customer experiences. What technologies can you implement to address CX?  Does technology help you solve your problem? A great way to begin your customer experience journey is a concept called journey mapping, one of the most powerful and deceptively simple tools for unlocking CX innovation at your organization. Here is where you can learn more about how you can bring this concept into your business to drive great customer experiences.

  • Collision with half of a semi-circle

    - by heitortsergent
    I am trying to port a game I made using Flash/AS3, to the Windows Phone using C#/XNA 4.0. You can see it here: http://goo.gl/gzFiE In the flash version I used a pixel-perfect collision between meteors (it's a rectangle, and usually rotated) that spawn outside the screen, and move towards the center, and a shield in the center of the screen(which is half of a semi-circle, also rotated by the player), which made the meteor bounce back in the opposite direction it came from, when they collided. My goal now is to make the meteors bounce in different angles, depending on the position it collides with the shield (much like Pong, hitting the borders causes a change in the ball's angle). So, these are the 3 options I thought of: Pixel-perfect collision (Microsoft has a sample) , but then I wouldn't know how to change the meteor angle after the collision 3 BoundingCircle's to represent the half semi-circle shield, but then I would have to somehow move them as I rotate the shield. Farseer Physics. I could make a shape composed of 3 lines, and use that as the collision object for the shield. Is there any other way besides those? Which would be the best way to do it(it's aimed towards mobile devices, so pixel-perfect is probably not a good choice)? Most of the time there's always a easier/better way than what we think of...

  • SEO and external sites that serve responsive images (like Re-SRC)

    - by Baumr
    Re-SRC is a tool that allows you to automatically serve responsive images for your website from their cloud servers. It delivers a new image file each time the browser window (viewport) is resized. To use it in your HTML when linking to an image, you would do the following: <img src="http://app.resrc.it//www.your-domain.com/img/img001.jpg"/> Some more background for SEO considerations: As an example, looking at their demo page's code, the src of the Arc de Triomphe photo — when the browser window is resized to be at a tablet-width — shows this particular file at it's widest. It is found under the following URL: http://app4-uk.resrc.it/s=w560,pd1/ro=h//www.resrc.it/img/demo/demo-image-1.jpg If the viewport is increased to desktop-width, then a smaller image is served in line with the design; see this URL: http://app4-uk.resrc.it/s=w320,pd1/ro=h//www.resrc.it/img/demo/demo-image-1.jpg If I change the viewport to be about half-way between those two, then the image's URL is: http://app4-uk.resrc.it/s=w240,pd1/ro=h//www.resrc.it/img/demo/demo-image-1.jpg In other words, I found that there is a separate file for every 10-pixel increment of the image width. Very cool for saving bandwidth on mobile devices and service responsive/retina images on others, but... Here are two problems I see for SEO: The img on your site, part of your semantic markup, will not be hosted on your site at all, or even a server you control. Any links to these images will pass on "link juice" to Re-SRC's site instead. You are serving a vast array of different image files to different people — some may link to one, others to another size. Then there's the question of what different search engine crawlers will see. Also: There seems to be no fallback option if their servers are down. Do you see any other concerns? Or, perhaps, do you not see those as concerns?

  • Advice on designing web application with a 40+ year lifetime

    - by user2708395
    Scenario Currently, I am apart of a health care project whose main requirement is to capture data with unknown attributes using user generated forms by health care providers. The second requirement is that data integrity is key and that the application will be used for 40+ years. We are currently migrating the client's data from the past 40 years from various sources (Paper, Excel, Access, etc...) to the database. Future requirements are: Workflow management of forms Schedule management of forms Security/Role based management Reporting engine Mobile/Tablet support Situation Only 6 months in, the current (contracted) architect/senior programmer has taken the "fast" approach and has designed a poor system. The database is not normalized, the code is coupled, the tiers have no dedicated purpose and data is starting to go missing since he has designed some beans to perform "deletes" on the database. The code base is extremely bloated and there are jobs just to synchronize data since the database is not normalized. His approach has been to rely on backup jobs to restore missing data and doesn't seem to believe in re-factoring. Having presented my findings to the PM, the architect will be removed when his contract ends. I have been given the task to re-architect this application. My team consists of me and one junior programmer. We have no other resources. We have been granted a 6-month requirement freeze in which we can focus on re-building this system. I suggested using a CMS system like Drupal, but for policy reasons at the client's organization, the system must be built from scratch. This is the first time that I will be designing a system with a 40+ lifespan. I have only worked on projects with 3-5 year lifespans, so this situation is very new, yet exciting. Questions What design considerations will make the system more "future proof"? What experiences have you had in designing such systems - both failures and successes? What questions should be asked to the client/PM to make the system more "future proof"?

  • Antenna Aligner part 1: In the beginning.

    - by Chris George
    Picture the scene, it's 9pm, I'm in my caravan (yes I know, I've heard all the jokes!) with my family and I'm trying to tune the tv by moving the aerial, retuning, moving the aerial again, retuning... 45 mins and much cursing later I succeed. Surely there must be an easier way than this? Aha, an app; there must be an app for that? So I search in the AppStore for such an app, but curiously drew a blank. Then the seeds of the idea started to grow. I can code, I work in a software house with lots of very clever people, surely I can make an app that points to the nearest digital tv transmitter! Not having looked into app development before, I investigated how one goes about making an iPhone app and was quickly greeted by a now familiar answer "Buy a mac!". That was not an option for many reasons, mostly wife related! My dreams were starting to fade until one of my colleagues pointed out that within Red Gate, the very company I work for, there was on-going development on a piece of software that would allow me to write an app using Visual Studio on a Windows machine, Nomad! Once I signed up for the beta program I got to work learning the Jquery mobile / Phonegap framework. Within a couple of hours I had written (in Visual Studio), built in the cloud (using Nomad) and published (via TestFlight) my first iPhone app onto my iPhone ! It didn't do much, but it was a step in the right direction. To be continued...

  • How to optimize calls to multiple APIs at once and return as one set?

    - by Martin
    I have a web app that searches across 2 APIs right now. I have my own Restful web service that I call, and it does all the work on the backend to asynchronously call the 2 APIs and concatenate them into one result set for my web app to use. I want to scale this out and add as many other APIs as I can (currently looking at about 10 more). But as I add APIs, the call to my service gets (potentially) slower and more complex. How do I handle one API not responding ... and other issues that arise? What would be the best way to approach this? Should I create a service call for each API, that way each one is independent and not coupled to all the other calls? Is there a way on the backend to handle the multiple API calls without all the extra complexity it adds? If I go the route of a service call per API, now my client code gets more complex (and I have a lot of clients)? And it's more work for the client, and since I have mobile apps, it will cost the client more data usage. If I go one service call, is there a way to set up some sort of connection so I can return data as I get it, in case one service call hangs?

  • Ubuntu 12.04 won't shut down - stopping winbind daemon

    - by jan
    My Precise Pangolin sometimes won't shut down - the screen is black with text on it. Mostly last line says something like "stopping winbind deamon" (sometimes also virtualbox, which is above winbind daemon; edit: sometimes the last line says "running unattended updates") and it stays like this for about ten miutes. Then I usually hold the power button for 5s to shut it down. It's very unpredictable - sometimes the computer shuts down without problem and sometimes it hangs. I've tried many ways to shut it down: HW button, panel applet, sudo shutdown -h now, sudo poweroff, sudo halt, etc. even sudo reboot or restart from panel applet have this problem. Sometimes it works ok but every method named hung at least once on the same (damned) line. My specs: FUJITSU SIEMENS LIFEBOOK E8310, Intel Core2 Duo T7300 @ 2.00GHz, 3GB RAM, GPU: Mobile Intel(R) 965 Express Chipset Family Ubuntu 12.04.2 32bit, 3.5.0-41-generic kernel (but it did it on older kernels and 12.04.x systems too). Any ideas what should I try next? Thanks a lot! Jan

  • Ubuntu One - Files API - Cloud - More detailed info somehwere?

    - by Brian McCavour
    I am just starting on a mobile app for Ubuntu One, and I'm reviewing the info at https://one.ubuntu.com/developer/files/store_files/cloud I find the information a bit lacking though. It's a nice reference, but for someone not familiar with it, I had to goggle search to find out what a "volume" was exactly (its kind of obvious, but never hurts to know the specifics) There's also things like: GET /api/file_storage/v1/volumes Return a JSON list of Volume Representations, one for each volume. A volume is a synced folder, or the Ubuntu One folder, owned by the user. Note that all volume paths begin with ~.: ... but there's no such thing as a JSON "list". Does it mean array ? And other things... So I was wondering if here existed another page with more detailed information. Maybe some sample request / responses or something? I could just write a little proof of concept app to answer some of these questions... but I prefer not to unless I have to. Thanks

  • Strange resolution on Ubuntu 11.10

    - by FSchmidt
    I only just installed Ubuntu 11.10, so excuse me if this question is silly ;-) I have a Fujitsu Esprimo Mobile V655, nvidia 8200 graphics, and recently installed Ubuntu 11.10 using wubi. I had to modify booting commands to include nomodeset; otherwise Ubuntu would not boot. Now I did set my screen resolution to 1280 x 720, which is the correct resolution for this screen. Still, the display seems imperfect. The font sizes seem unnatural(too large / stretched) and text is quite blurry (especially in Firefox). Could it have something to do withe the nvidia graphics driver and/or the nomodeset parameter? How can I fix this? Update: I used jockey-gtk to update nvidia to the current version. This improved the resolution dramatically (no blurriness, fonts are good). It also means that I no loger need to include nomodesetin the boot commands. However, other problems were brought up by this. It seems that certain files cannot be accessed - icon (images) are missing, some task bars are completely unstyled (grey, block-form, win97 style). I also get this error message(roughly translated from German, so may be slightly different from actual) every time I reboot: Could not apply the stored configuration for the monitor: none of the chosen modi is compatible with the available modi. I have tried nvidia-xconfig, unity --reset , no improvements. Can anyone help, please?

  • Should I listen to my employer and use CASE tools?

    - by omsharp
    My employer (Not a Developer) thinks that CASE tools will help us improve our development process and documentation. I am not sure about that, we are a small team of 5 developers building mobile banking solutions for local clients. I think CASE tools will be a waste of time and money as they need to be purchased and we will need some time before we get used to them and be efficient working with them for modeling and stuff. Code generation is another issue, I really think that the CASE generated code won't be as good as code written by good developers. I think that if we stick with agile princeliness, design patterns, use TDD, and keep our code clean. we should be good. And as far as Analysis and Design, I think simple UML diagrams on whiteboard should do the trick. Documentation is good and important, but should be made as little as possible and we should not focus on Docs and forget the code. This is what i think. Am I correct? or should I listen to my employer and start researching for an appropriate CASE Tool?

  • Artists and music - i need help to decide wich cms to use.

    - by infty
    A friend has asked me to build a site with the following options: staff members must be able to add new music and artists to the page a gallery must be provided - it is also good if each artist has the ability to have his/her own, smaller, gallery users must be able to vote for artists users must be able to alter in discussions (forums or comments sections) staff members must be able to blog staff members must be able to write articles I did a small project where i actually implementet all of these features, but i want to use an existing content managment system for all of these features so that future devolpers can, hopefully, more easy extend the website. And also, so that i dont have to provide to much documentation. I have never developed a website using an external cms like drupal or wordpress and after seeing hours of tutorial videos of both systems, i still cant make up my mind on wheter i should : a) use Drupal 7 b) use Wordpress 3 c) create my own cms I can only imagine that staff members would also want to create content using iphone or android based mobile devices. But this is not a required feature. Can someone, with experience, please tell me about their experiences with bigger projects like this? The site will approx. have a total of 400 000 - 500 000 visitors (not daily visitors, based on numbers from last year in a period of 4 months)

  • Am I missing something about these considerations about Leaderboard's database's schema?

    - by misiMe
    I just finished to develop a mobile game, now I want to implement an online leaerboard using mysql. I'm wondering about the database's schema, I thought about some possibilities: (I didn't got in detail with syntax because my question is just about the logic of it) Name: string; Score: integer I thought to ask the name just the first time. If, in the future, you will modify that, it will call just an update to the name associated with your id. Leaderboard(ID, Name, Score) ID: integer autoincrement, PrimaryKey With this kind of idea maybe the db will grow fast because if you choose everytime a different name for the score, it will add a new entry. Leaderboard(PhoneId, Name, Score) Here PhoneId will be the unique identifier of the phone, PrimaryKey. A con of this choice is that if you want to play with your friends' phone, you can't put a different name for the score. Leaderboard(Name, Score) Here Name is PrimaryKey. With that, if you enter a name that already exists, you will be prompted to choose another one. Do you agree with this considerations? What will you do? Am I missing something?

  • How to handle the different frame rate on different devices?

    - by Fenwick
    I am not quite sure how frame per second works on a web page. I have a Canvas game that involves in moving an image from point A to B, and measuring the time elapsed. The code can be as simple as: var timeStamp = Date.now(); function update(){ obj.y += obj.speed; text = "Time: "+ (Date.now() - timeStamp) + "ms"; } The function update() is called every frame. The problem is that the time elapsed is different from device to device. It is pretty short on my PC, but get longer on my iPad, and is much longer on my cell phone. I thought it is because the FPS is smaller on mobile devices, so instead of calling update() every frame, I call it every 1ms by using a setInterval. But this does not solve the problem. In my understanding, the function for setInterval is invoked based on the increment in system time, other than frame rate, so it should fix the problem. Am I missing anything here? If the setInterval function is called based on FPS, is there any way to get around with the FPS difference across devices? On a side note, I have sort of a "water simulator" on the same canvas. It involves in redrawing about 60 objects which can be 600x600 pixels for every frame, so it could be a frame rate killer. I am using Phaser.js but not really using much of its functionalities, if that helps.

  • Should Android and iPhone UI be different?

    - by Phonon
    I'm not completely new to developing apps, but I'm at a point where I'm trying to develop something and deploy it on several mobile platforms. To only concentrate on two major ones, suppose I'm developing an app for Android and iPhone and designing UI and the general user interaction architecture. Both platforms give guidelines as to how their UIs should work. For example, most iPhone apps have the Navigation Bar (the one that says Testing 1 and has a Back button) and an Icon Bar for navigating a program, while Android uses an Options Menu fetched via a Menu button and the "back" navigation is handled with the physical Back button on the device. I've seen many apps that try to force the same UI on every platform. For example, custom-building an iPhone style Icon Bar and putting it in their Android apps, but it just doesn't quite look right to me and it feels like it violates UI design guidelines somewhat. Are there any good design patters for implementing something sufficiently similar on both platforms, yet still platform-specific enough so that the user would not feel out of their comfort zone? What do people usually do in these situations?
