• Why don't we use browser detection and platform-specific CSS?

  - by Pankaj Upadhyay

  Nowadays, the common phenomena is to develop a website for a browser and then corresponding apps for Android phones, iPhone, tablets and so on. Since all the platforms come with a browser, why aren't companies using CSS to accommodate them? Surely we can detect from the request which browser was used and from which platform the request came. Reading those values, why don't we just implement the corresponding CSS for different platforms. Like we do for IE, Chrome and Safari. This way we can use the platforms' browser capabilities and don't need to develop subsequent apps for a platform.

• Dropping the full-time high-pay gig - I need help choosing a smart path that I can rely on to produce enough to survive comfortably ($2,500 per month)

  - by Jeff V

  I have about 6 years of full time experience developing web applications and tools. I know perl, python, PHP, ruby, and a good deal of SQL and relational theory. I have never had to choose a self-employed path as I have always had full time work or a bank account (credit cards) to support a big project. I'm planning to move out of the country to an area that will not offer local employment, and need some advice on what to focus on. I want to move in no more than six months, I have enough savings to live for an additional six months, but I would like to conserve it as much as possible. I enjoy taking risks, so I'm not looking for discussion of whether this is a good idea or not. I want advice on the most reliable solution given my skill set. Some paths I'm considering: Learn objective-c and build quality Apple software. Develop subscription based web tools for SEO, or other Marketing applications Attempt to acquire freelance projects by developing a reputation within open source projects, freelancer.com, and other online communities The last time I left my job, I was building a startup (that went under), and missed out living in a beautiful place due to the amount of time I worked. I would like to work 30-40 hours per week max. I can dedicate 10-15 hours per week while at my current job to prepare and learn. A preemptive thanks for the advice...

• Looking software for making an animated cartoon to present a new application/scenario idea [closed]

  - by Skarab

  I have an idea for an application (+usage scenario) and I would like to create an animated cartoon that shows a use case for this application and its novelty. My company is a rather big so I am looking for an interesting way to get people know my idea to get feedback/get a green light to further develop it. Therefore I am looking for an application (free or commercial) that I could use to realize such an animated cartoon. I have posted this quesion before on stackoverflow, but I think this might be a better community to ask such a question.

• Does the app need to be run from /opt directory for in the Ubuntu App Showdown?

  - by costales

  I read this question, but I'm more confused yet. In developer.ubuntu.com/showdown I read: "(2) run out of /opt" (I understand "run out" is not in /opt :O Am I wrong?) In https://wiki.ubuntu.com/AppReviewBoard/Review/Guidelines#Packaging I read: "our package should install most files in /opt/extras.ubuntu.com/" It's not clear for me if the app must be in the /opt or out /opt :$ Then, can I use the /usr? Will be the app rejected if it's on /usr? Thanks! :)

• Rules of Holes -#1: Stop Digging

  - by ArnieRowland

  You may have heard of the 'First Rule of Holes'. It goes something like this: " When you suspect you might be in a hole, stop digging. " That seems like obvious, and good advice, but what does it really mean? How does the Rule of Holes apply to you? How does it apply to your job? When things are not going right, stop doing the "same ol', same ol'" You find yourself involved in doing the same type of coding over and over. Maybe it's time to stop, step back, take a little time and learn something new....(read more)

• How quickly does a language get outdated?

  - by Dummy Derp

  I started learning Java recently. I started learning it using books that I picked up from the library, some that I bought, and here and there from Java documentation. The book that I use for Java was published in the year 2011. In 2012, Java8 will be released followed by Java9 in the year 2013. The questions are: How do I keep myself updated about developments in Java without having to buy a tome for Java8 and/or Java9 Is a book published in 2008 an outdated book for studying JSP and Servelets? I'm talking about Head First Servlets and JSP

• Javascript Event in Innerhtml Resulting from PHP Server Script

  - by user144527

  I'm (very slowly) making a website, and I'm creating a search engine for the database, which is essential to organize the dependencies during data entry. Anyway, what I would like is to type a few keywords into a box, have a menu pop up with various search results, and have the box fill with the ID number of the selected entry when it's clicked. Currently, I have a document called search.php which fills a div called search-output using xmlhttp.open() and the innerhtml property. Everything is working perfectly except for filling the original search box with the ID number when clicking. My first attempt was to add an onclick event to each entry in the output from search.php. Unfortunately, I found that javascript inserted into innerhtml is not run for security reasons. I've been Googling for hours but haven't been able to find a solution. How can I get the original search text box to fill with the correct ID when I click it? Is what I'm doing a good setup for the results I desire, or is there a better way to integrate search features into data entry?

• 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?

• Language-independent sources on 2D collision detection [on hold]

  - by Phazyck

  While making a Pong clone with a friend, we had to implement some 2D collision detection. For research purposes, my friend dug up a book called "AdvancED Game Design with Flash" by Rex Van Der Spuy. This book was clearly targeted at implementing 2D collision detection in ActionScript, and I also have some problems with how the concepts are presented, e.g. presenting one method as better than another, without explaining that decision. Can anyone recommend some good material on 2D collision detection? I'd prefer it if it kept the implementation details as language-independent as possible, e.g. by implementing the concepts in pseudo-code. Language-specific materials are not completely unwelcome though, though I'd prefer those to be in either Java, C#, F# or Python or similar languages, as those are the ones I'm most familiar with. :-) Lastly, is there perhaps widely known and used book on collision detection that most people should know about, like a 'the book on 2D collision detection'?

• What is best way to create a cross fade effect?

  - by Starx

  While creating an Image Slider, cross-fade is one of most popular effects so far. Various slider on the internet use various techniques to create such effect. Major technique I have found so far are two: Some use a overlay and underlay div and fade in and out each others visibility. While others, create a div of exact size of the slider on the slider-initialization and play with its z-index property and then fade each other consequently. Disregarding them, what is a proper way or much better way to create a cross fade effect. P.S: I would love to read answer in form of algorithm.

• java developer who wants to raise skill level for better career growth [closed]

  - by Rahul Shivsharan

  I have an experience in Java language and in JEE related Framework for about 5 years. In these 5 years i have worked on Core java, Spring, Hibernate, JPA, Struts 1. Now just to be prepared for the near future, i am thinking to learn some new programming language or some new technology, this will help me out to be a more elligible employee. So my question to you is, which new technology or language should i learn, my target is for next 3 years. So just in case if Java fades out (thought it won't) than i can jump on to this newly learned stuff. Where should i start from ? Should i learn some other language in JVM like Scala, Clojure, Groovy, JRuby ? Or should i learn some altogether different language like Python or Erlang, Perl ? Or new technology which is related to NoSQL, like MongoDB, Hadoop, CouchDB. Or learn few current happening things in market like RoR, Node.js, LessCss or Sass, Coffee Script ? Can anybody give me some hint,

• Rules of Holes #3: A Better Shovel is NOT the Answer!

  - by ArnieRowland

  You stopped digging. You looked around and saw that you were still in the Hole. You needed to get out. AHA! Problem solved, you thought. You'll just get a better and more efficient shovel! I regret to tell you that the Third Rule of Holes applies: Switching to a more efficient shovel is unlikely to help you get out of the Hole . Yes, your resumed digging may be faster, more directed, and even well planned and articulated. But you will still be in the Hole, and digging. And that's just not the solution....(read more)

• Connect a method for window destroy

  - by Roberto

  I have a main window with a Gtk Button named openDialog. If I click on this button another Window (addName) popups.

I would like to run this printHi method (in my main window file), when addName window is destroyed. I tried something like this: def on_addName_destroy(): printHi() But it doesn't work. Any suggestion?

• How to prioritize tasks when you have multiple programming projects running in parallel?

  - by Vinko Vrsalovic

  Say you have 5 customers, you develop 2 or 3 different projects for each. Each project has Xi tasks. Each project takes from 2 to 10 man weeks. Given that there are few resources, it is desired to minimize the management overhead. Two questions in this scenario: What tools would you use to prioritize the tasks and track their completion, while tending to minimize the overhead? What criteria would you take into consideration to determine which task to assign to the next available resource given that the primary objective is to increase throughput (more projects finished per time unit, this objective conflicts with starting one project and finishing it and then moving on to the next)? Ideas, management techniques, algorithms are welcome

• Why my MainWindow doesn't get he focus?

  - by Roberto

  window = self.builder.get_object("main-window") print window.get_focus() print window.has_focus() print window.is_active() print window.has_toplevel_focus() Terminal output: <MainWindow object at 0x28c26e0 (Mainwindow at 0x26a1210)> False False False So I got the right answer on get_focus(), but when I ask is MainWindows has the focus, it is return with False. Why? I don't understand it. I would like to write a method to focus_changed, but I can't if it doesn't works.

• How to find out when to increase bit rate? (TCP streaming solution)

  - by Kabumbus

  How to find out when to increase bit rate? (TCP streaming solution) We have a stream with "frames". each "frame" has a "timestamp" . frames have bit rate property which is actually there size. We generate frames with our app and stream them one by one on to our TCP server socket. At the same time server post replies so when after each sent frame we try to read from socket we receive which timestamp is currently on server. if timestamp is lover than previous frame we lover bit rate 20%. Such scheme seems to work giving me one way vbr (lowering) but I wonder how to implement increase? I mean we can always try to increase 5% each frame until some limited desired value but each time we have delay will lose real-time feature of our stream... Generally such scheme is for finding out how much of network stream is currently used by other user apps and give picture of how much server is loaded at the same time so we can stream just right amount of data for all to receive it in real time. So what shall I do to add increase to my scheme? So having current bit rate of A I thought we could add +7% for 3 frames and than one -20% and than if all that 3 frames with +7% came in time we could add 14% to A and repeat circle and it would hopefully not be really noticeable if 2nd frame wold come to us with delay... probably this one is too localised because it is a requirement for me to use TCP.

• Is Java a good choice for cross-platform games?

  - by CommunistPancake

  I'm looking to create a game in Java and would like it to work on Windows, Linux, and Mac. I'm pretty sure C# is a bad choice for this, and I don't have enough experience in C or C++. I want to stay away from Flash. Therefore, Is Java a good choice for me? Mostly, I use C#, and think that Java is similar, so I assume it won't be that hard to learn. But is it fast enough? Is there a language more suited for my needs than Java?

• Website creation preparation [closed]

  - by Loki

  I am in the pre-coding phase of creating a website. I know that it will be account based (users have to register/login to use the features). I also know that the server will have to do certain operations that are timer based, that is to say that user will have events that will trigger at a point chosen by the user and do something. I am searching for a good choice in server-side technology, and was wondering what my options are and what the best choice is. I would prefer open technology and something that doesn't use interpreted languages (Java, .net). My first thought is PHP + PGSQL for serverside and HTML+CSS+JS for clients, but I am still looking at my options.

• Problem with 'insert_at_cursor' attribute

  - by mivoligo

  I made something, so after clicking a button, some text should appear in the TextView. Part of my code: def on_button1_clicked(self, builer): self.writetest = self.builder.get_object("textview1") self.writetest.insert_at_cursor("something") Unfortunately, when I click the button I get: AttributeError: 'TextView' object has no attribute 'insert_at_cursor' According to GTK Documentation there is such attribute: http://developer.gnome.org/gtk3/stable/GtkTextView.html#GtkTextView-insert-at-cursor I have the same problem with Entry as well, if I change TextView to Entry. But if I use set_text instead of insert_at_cursor in my code, it works.

• secure offline PC storage accessible through javascript

  - by turbo2oh

  I'm attempting to build a browser-based HTML5 application that has the ability to store data locally on a PC (not mobile device) when offline. This data is sensitive and must be secure. Of course the trick is trying to find a way to be able to access the secure data with Javascript. I've ruled out browser local storage since its not secure. Could this be accomplished with a local database? If so, where could the DB credentials be stored? Javascript obviously doesn't seem like a good option to store them since its user-readable.

• Stop myself from over-complicating applications

  - by stuartmclark

  Recently I worked on a fairly large project involving C# and MVVM. This application had around 160 projects in the solutions each seprarated into their own layers. As I have been working on this application for almost a year, building it from scratch as part of a team, I am now coming off that project and onto smaller more trivial projects. As I was beginning to develop a small in-house tool I found myself trying to mimic the larger applications structure and layering but in the end I just had a simple application with several DLLs which I know I wouldn't have done if I had not worked on that larger application before. I am just wondering if there are any techniques I can utilise to stop myself from turning a "code-behind" style trivial application into a full blown MVVM application? Or should I continue developing as I am and try to keep the unnecessary fluff out of the project?
