• 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.

• Get selected object from TreeView

  - by GoGoDo

  I've been working on a minor (first time) app with quickly and hit a hurdle - how do I get the selected row (the data) from a TreeView? The data to the TreeView is passed from a list of files in a directory, and I need to know which rows were selected (and thus which files were). What is the best way to do that? Here's the current code: self.treeview = self.builder.get_object("treeview") select = self.treeview.get_selection() select.connect("changed", self.on_tree_selection_changed) def on_tree_selection_changed(selection): model, treeiter = self.treeview.selection-get() if treeiter != None: print "You selected", model[treeiter][0]

• 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...

• In what order do people build websites?

  - by Corey

  For a website, you need to have an idea, you need to have a design and you need to have data, events and output, right? Whether it be a blog, web app, Q&A site, search engine... Anyway, that is only slightly related to my question. My question is, when designing a website, providing I know the purpose, what should I start with? Should I start with the CSS, design and look&feel using dummy data first, or should I program in the logic, events and output, and style it later? What is the design process of most websites that are built from the ground up?

• How long did you stay in your first programming job?

  - by Anon

  I've been in my first programming job for just under 2 years now (it will be two years next month). I went from Junior Developer initially to just Developer after about a year (when the senior developer left). It's a small company and I write all the code. I have been offered a cool new job (Windows 8, Visual Studio 2012, SQL Server 2012, MVC etc etc) and I am considering it not because I hate my current job (I don't, it's fun) but because I am scared that if I stay in the one job for too long, other employers won't want to hire me as it will look like I can't get a job anywhere else. It would help a lot if you could answer this question: How long did you stay in your first programming job? Thanks

• 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?

• 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'?

• 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?

• Should I make my project free software?

  - by SkyDan

  The story Over the last couple month I have been working on a pretty big project. It's an enterprise-level software, I designed to be used at a local gym, but I believe it can be used in other places, where things like keeping track of clients, attendances, purchases and payments are required. The problem Well recently, I started to think on how to mature this project from being home-made. Not just because I want my project to grow but also because I would like to have some gain from it. The solutions? And here I saw 2 paths: License the software under some restricted license and try to sell the software to other business around. This way I can get some money for college (I am a high school junior right now) License the software under some free license, publish it on GitHub or something, and try to engage other developers to participate in the project. This way I get experience of working in a team and a better chance that the project will keep growing. The latter would be a good + for my resume, when I'll trying to find a job. So far both ways seem pretty exciting and beneficial to me. The first one offers a good college career, while the second one offers some additional experience and the project's growth. The questions Can anyone point to some other +/- of these 2 options? What would the better option in my situation and why? Or are there other options?

• 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

• 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.

• 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.

• 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.

• I've totally missed the point of distributed vcs [closed]

  - by NimChimpsky

  I thought the major benefit of it was that each developers code gets stored within each others repository. My impression was that each developer has their working directory, their own repository, and then a copy of the other developers repository. Removing the need for central server, as you have as many backups as you have developers/repositories Turns out this is nto the case, and your code is only backed up (somewhere other than locally) when you push, the same as a commit in subversions. I am bit disappointed ... hopefully I will be pleasantly surprised when it handles merges better and there are less conflicts ?

• Why would he say "We don't want to support MVC3"?

  - by MadBurn

  I work in a small shop at a fairly big company doing intranet web applications. By small, I mean there is 1 other guy in my position... and he graduated with me last December. (we aren't the only IT, but the only ones in our field) We are switching out an old COBOL system and converting it's only used application suite to a Web App. My company has contracted to a Web Application firm to help with this process who has chosen ASP.NET MVC, during one of the important meetings I asked if they will be using MVC2 or MVC3. Their lead developer said: "MVC2, we don't want to support MVC3. haha" My question is, why is this? This was several months ago and I've been doing extensive and self training gearing up for the MVC switch. From everything I am understanding, MVC3 is just like MVC2 if you don't use Razor and it fixes a number of smaller bugs that MVC2 had. So in my eyes, I can't see any reason to NOT use MCV3. There has to be something I'm missing. Since I don't really have any mentors to turn to in the real world, I'm coming here. What problems are there with MVC3 that might possibly lead him to say this that I'm missing?

• 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)

• HTML, JS, CSS Engines

  - by Pius

  I am just messing around, trying to figure out how stuff works and right now I have a couple questions about HTML, JS and CSS engines. I know there are two major JavaScript engines out there - V8 and JavaScriptCore (WebKit's JS engine as far as I know). Is that correct? And what are the main HTML + CSS renderers out there? Let's say I want to build a web browser using V8 (I saw it has some documentation and stuff + I like the way it works), what are the best options for me? Partially another question. Is there any bare browser that uses V8 and runs on Ubuntu at least? P.S. I am a Ubuntu user and prefer C++.

• I'm working on my resume for a job fair this week; any tips? [closed]

  - by buu700

  This will change as I update the document, but here is my resume. The job fair I'm going to is really huge (very good chance that it will determine where I intern this summer), so I would definitely appreciate any possible assistance in polishing this up. Any advice possible will be appreciated, ranging from spacing or absurdly minor formatting issues, to rearranging bullet points, to browser incompatibilities, to major changes in anything I've organised or written. At the moment, my only specific question is whether easter eggs are acceptable (specifically, if representatives who understand the reference will generally frown upon my inclusion of "Hacked The Gibson", given the context). Also, if anyone wants to evaluate it (e.g. font size, final arrangement, etc.), here is a PDF snapshot of the document at the time this question was submitted (the final version will have a different file name and appropriate metadata, for the record). Thanks!

• Where should I start and how to progress when learning Java EE

  - by danizmax

  I know basic stuff like, what are beans, jsp, servlet, jsf and how this stuff should work together. I know how to make basic jsp page with database query for example. Now I need to know what is the best path to learn all this stuff. My plan is to learn in this order: jsp (including persistance and JSTL) servlets + beans jsf The jump to frameworks (hibernate, struts, spring, etc) Also I'm not exactly sure about JSF, is it a must to make great pages or is it just a convenience to know?

• 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

• 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?
