• What operating systems are used in airplanes, and what programming languages are they developed in?

  - by adhg

  I was wondering if anyone knows what is the operating system used in commercial airplanes (say Boeing or Airbus). Also, what is the (preferred) real-time programing language? I heard that Ada is used in Boeing, so my question is - why Ada? what are the criteria the Boeing-guys had to choose this language? (I guess Java wouldn't be a great choice if the exactly in lift off the garbage collector wakes up).

• How to blacklist a PCI device so a system can boot?

  - by Reda Lazri

  I installed Ubuntu 10.10 on someone's computer which it had a 'Connexant Fusion 878A' PCI card installed, the card is problematic, I had to unplug it just to use the Live CD. Now my question is how to know which module to blacklist, so he can use the card in Windows and override it when he boots into Ubuntu. There's a twist, I can't plug it and lsmod it because it won't let the system boot up even in 'Recovery Mode'. Kernel: 2.6.35-22

• How portable are Binaries compiled in Ubuntu?

  - by hiobs

  The title says it all, actually. But allow me to specify the question: Assuming I were to compile an application that uses libffi, libGL, dlfcn, and SDL, would said binary run on other Linux distributions with same architecture, etc? The reason I ask is because of the directory /usr/lib/i386-linux-gnu - I might be wrong, but I assume this directory is something rather Ubuntu-specific, no? So, how portable are binaries compiled on Ubuntu really?

• iOS + cocos2d: how to account for sprite's position for the different device dimensions in an universal app?

  - by fuzzlog

  All the questions I've seen regarding iOS universal apps (with or without cocos2d) deal with the "how to add graphics to a universal app". My question is, how does the code need to be written to ensure that the sprites appear appropriately on the screen (given that an iPhone 5's resolution is not proportional to an iPad's resolution)? Is it just a bunch of "if" statements and duplicate code or do iOS/cocos2d provide common function calls that will place the sprites at an appropriate position?

• What's on Azure right now?

  - by RobbieT

  If you speak to Microsoft, they'll give you a number of active accounts, but what are those accounts actually running? It could be a collection of Hello World ASP.NET sites, or perhaps small exciting web start-ups, or maybe even the beginnings of large corporate moves to the cloud! I guess what I really wanted to know was who is using Azure but that's a much harder question to answer, so we'll stick to what for now. My super awesome comrade Theo Spears attempted to answer this by trawling every...(read more)

• Part 5: Choose the right tool - or - why

  - by volker.eckardt(at)oracle.com

  Consider the following client request “Please create a report for us to list expenses”. Which Oracle EBS tool would you choose? There are plenty of options available: Oracle Reports, or BI Publisher with PDF or Excel layout, or Discoverer, or BI Publisher Stand Alone, or PDF online generation, or Oracle WebADI, or Plain SQL*Plus as Concurrent Program, or Online review option … Assuming, you as development lead have to decide, you may decide by available skill set in your development team. However, is this a good decision? An important question to influence the decision is the “Why” question: why do you need this report, what process is behind, what exactly you like to achieve? We see often data created or printed, although it would be much better to get the data in Excel, and upload changes via WebADI directly. There are more points that should drive your decision: How many of such requirements you have got? Has this technique been used in the project already? Are there related reusable’s you may gain from? How difficult is it to maintain your solution? Can you merge this report with another one, to reduce test and maintenance work? In addition, also your own development standards should guide you a bit to come to a good decision. In one of my own projects, we discussed such topics in our weekly team meeting. By utilizing the team knowledge best, you may come to a better decision, and additionally, your team supports your decision. Unfortunately, I have rarely seen dedicated team trainings or planned knowledge transfer to support such processes. Often the pressure to deliver on time is too high to have discussion and decision time left. But exactly this can help keeping maintenance costs low by limiting the number of alternative solutions for similar requirements. Lastly, design decisions should be documented to allow another person taking this over easily. Decisions shall be reviewed and updated regularly, to reflect related procedures or Oracle products respective product versions. Summary: Oracle EBS offers plenty of alternatives to implement customizations. Create and maintain a decision tree to support the design process. Do not leave the decision just on developer side. Limit the number of alternative solutions as best as possible; choose one which is the most appropriate also from future maintenance perspective.

• Can someone sue me/take my domain?

  - by qwerty

  I have found a great domain that isn't in use, but the .com and .net domains are already taken. There's nothing on the domains though, it just says they are registered with Network Solutions and are under construction. My question is: If i buy the .org version of the domain, and the .com guys later start a company on that domain, can they sue me or make me change name because it is too similar to their .com domain? Should i avoid using domains that have already been registered but with a different ending?

• Website Registration Date

  - by Matt Walker

  I recently registered a website : cinematrailers.net. I was aware that this domain was expired ( registered in 2007 until 2011) My question is when I go to view the registration date on this domain, it says 2012 instead of 2007. Why is that when it was clearly registered in 2007? And will this affect seo? I was under the assumption that the domains age would be great for seo, but now I'm not sure.

• Programming Languages

  - by Shannon

  I realize this will be a very vague question, but please bear with me. I have a concept for an open-world game, hand to hand combat, with a fairly open storyline, but there is an issue. I'm not sure which programming language to use, as I'm fairly new to programming. I am considering c++, but I would like to hear your opinions on which language you believe would support this type of game most efficiently. Pros and cons would be appreciated.

• Understanding the levels of computing

  - by RParadox

  Sorry, for my confused question. I'm looking for some pointers. Up to now I have been working mostly with Java and Python on the application layer and I have only a vague understanding of operating systems and hardware. I want to understand much more about the lower levels of computing, but it gets really overwhelming somehow. At university I took a class about microprogramming, i.e. how processors get hard-wired to implement the ASM codes. Up to now I always thought I wouldn't get more done if learned more about the "low level". One question I have is: how is it even possible that hardware gets hidden almost completely from the developer? Is it accurate to say that the operating system is a software layer for the hardware? One small example: in programming I have never come across the need to understand what L2 or L3 Cache is. For the typical business application environment one almost never needs to understand assembler and the lower levels of computing, because nowadays there is a technology stack for almost anything. I guess the whole point of these lower levels is to provide an interface to higher levels. On the other hand I wonder how much influence the lower levels can have, for example this whole graphics computing thing. So, on the other hand, there is this theoretical computer science branch, which works on abstract computing models. However, I also rarely encountered situations, where I found it helpful thinking in the categories of complexity models, proof verification, etc. I sort of know, that there is a complexity class called NP, and that they are kind of impossible to solve for a big number of N. What I'm missing is a reference for a framework to think about these things. It seems to me, that there all kinds of different camps, who rarely interact. The last few weeks I have been reading about security issues. Here somehow, much of the different layers come together. Attacks and exploits almost always occur on the lower level, so in this case it is necessary to learn about the details of the OSI layers, the inner workings of an OS, etc.

• Web browser crashed whilst EasyApache was running

  - by Silver89

  I was building and updating my server using EasyApache when the web browser crashed, the browser then restarted and I think tried to run another of the EasyApache build which failed .. possibly due to the previous one still running? My question is would the first one still be running in the background but I just can't view it anymore? Is there anyway to check that the first one built and finished okay?

• Ranking on the First Page in Search Engines

  How important is it to rank on the first page of the search result pages displayed by search engines when keywords are typed in and the enter key is pressed? This is a question that every website administrator must have asked himself at least a zillion times during the course of optimizing his website and continues to ask himself even though his website has been fully optimized and it has achieved a ranking on the search engines.

• Why can't `main` return a double or String rather than int or void?

  - by sunny

  In many languages such as C, C++, and Java, the main method/function has a return type of void or int, but not double or String. What might be the reasons behind that? I know a little bit that we can't do that because main is called by runtime library and it expects some syntax like int main() or int main(int,char**) so we have to stick to that. So my question is: why does main have the type signature that it has, and not a different one?

• Making a file with terminal commands?

  - by iSeth

  In Windows I can write a file containing commands for cmd (usually .cmd or .bat files). When I click on those files it will open cmd.exe and run them commands the file contains. How would I do this in Ubuntu? I'm sure this is a duplicate, but I can't find my answer. Its similar to these questions, but they don't answer the question: Store frequently used terminal commands in a file CMD.exe Emulator in Ubuntu to run .cmd/.bat file

• Attending my first software conference - any tips before I go? [closed]

  - by Paul Weber

  My nice employer allowed me to visit a software conference in June (International PHP Conference, for those who care). Wanting to make the most of it, I would ask the more experienced conference goers in here to give me some tips on what I could do to maximize my learning experience on the conference, and to reduce beginner mistakes. Sorry that this question is a little ambiguous, but I think it's best to keep it a little bit more open, so I can get a wide range of Ideas, and it will be of more use to further people seeking for an answer.

• Is it wrong to tell mobile users to view a site on their computer?

  - by betamax

  I am creating a web application that doesn't work correctly on mobile. I don't want to make it work on mobile because I would rather mobile users have a fully integrated experience and not have to use the web version. This mobile version will be released at a later date based on reaction to the initial web-based version. So, my question is: Is it wrong to not allow mobile users to use the site and instead show them some sort of splash screen telling them to come back to the site on a computer?

• Draw images with warped triangles on a web server [migrated]

  - by epologee

  The scenario The Flash front end of my current project produces images that a web server needs to combine into a video. Both frame-rate and frame-resolution are sizeable enough that sending an image sequence to the back end is not feasible (in both time and client bandwidth). Instead, we're trying to recreate the image drawing on the back end as well. Correct and slow, or incorrect and fast The problem is that this involves quite a bit of drawing textured triangles, and two solutions we found in Python (here and there) are so inefficient, that the drawing takes about 60 seconds per frame, resulting in a whopping 7,5 hours of processing time for a 30 second clip. Unacceptable. When using a PHP-module to send commands to ImageMagick for image manipulation, the whole process is super fast (tenths of a second per frame), but ImageMagick seems to be unable to draw triangles the way we do it in the front end, so the final results do not match. Unacceptable. What I'm asking here, is if there's someone who would know a way to solve this issue, by any means necessary that would run on a web server. Warping an image Let me explain the process of the front end: Perform a Delaunay calculation on points in an image to get an evenly distributed mesh of triangles. Offset the points/vertices in the mesh, distorting or warping the image. Draw the warped triangles on a new bitmap. We can send the results (coordinates) of steps 1 and 2 to the back end, to then draw the warped triangles and save it to an image on disk (or append as a frame to the video). But that last step is what I need help with. The Question Is there an alternative to ImageMagick that can draw triangles in a bitmap? Is there some other library, like a C library, that would allow us to do this? Or could we achieve this effect more easily by switching back end technologies, like Ruby? (.Net and Java are, unfortunately, not really options right now) Many thanks. EP. P.S. I'd appreciate re-tagging efforts, I don't quite know what labels to put on this question. Thanks!

• Separate Action from Assertion in Unit Tests

  - by DigitalMoss

  Setup Many years ago I took to a style of unit testing that I have come to like a lot. In short, it uses a base class to separate out the Arrangement, Action and Assertion of the test into separate method calls. You do this by defining method calls in [Setup]/[TestInitialize] that will be called before each test run. [Setup] public void Setup() { before_each(); //arrangement because(); //action } This base class usually includes the [TearDown] call as well for when you are using this setup for Integration tests. [TearDown] public void Cleanup() { after_each(); } This often breaks out into a structure where the test classes inherit from a series of Given classes that put together the setup (i.e. GivenFoo : GivenBar : WhenDoingBazz) with the Assertions being one line tests with a descriptive name of what they are covering [Test] public void ThenBuzzSouldBeTrue() { Assert.IsTrue(result.Buzz); } The Problem There are very few tests that wrap around a single action so you end up with lots of classes so recently I have taken to defining the action in a series of methods within the test class itself: [Test] public void ThenBuzzSouldBeTrue() { because_an_action_was_taken(); Assert.IsTrue(result.Buzz); } private void because_an_action_was_taken() { //perform action here } This results in several "action" methods within the test class but allows grouping of similar tests (i.e. class == WhenTestingDifferentWaysToSetBuzz) The Question Does someone else have a better way of separating out the three 'A's of testing? Readability of tests is important to me so I would prefer that, when a test fails, that the very naming structure of the tests communicate what has failed. If someone can read the Inheritance structure of the tests and have a good idea why the test might be failing then I feel it adds a lot of value to the tests (i.e. GivenClient : GivenUser : WhenModifyingUserPermissions : ThenReadAccessShouldBeTrue). I am aware of Acceptance Testing but this is more on a Unit (or series of units) level with boundary layers mocked. EDIT : My question is asking if there is an event or other method for executing a block of code before individual tests (something that could be applied to specific sets of tests without it being applied to all tests within a class like [Setup] currently does. Barring the existence of this event, which I am fairly certain doesn't exist, is there another method for accomplishing the same thing? Using [Setup] for every case presents a problem either way you go. Something like [Action("Category")] (a setup method that applied to specific tests within the class) would be nice but I can't find any way of doing this.

• If you had to teach professional development to students that just graduated school, what would be the topics?

  - by user2567

  The idea is to give them more chances to be efficient in a professional environment. Most students are good with theory, most of them are smart, but they have to learn how to solve common technical problems. They will be better programmers as they practice, but maybe we can help them with some introduction training. Which topics you would select for a two weeks full time training? It's an open question, I don't want to suggest things that will reduce the answers to a particular field.

• Reading input all together or in steps?

  - by nischayn22

  For many programming quizzes we are given a bunch of input lines and we have to process each input , do some computation and output the result. My question is what is the best way to optimize the runtime of the solution ? Read all input, store it (in array or something) ,compute result for all of them, finally output it all together. or 2. Read one input, compute the result, output the result and so on for each input given.

• Client-side prediction for FPS

  - by newprogrammer

  People that understand client-side prediction and client-side interpolation, I have a question: When I play the game Team Fortress 2, and type cl_predict 1 into the developer's console, it enables client-side prediction. The also says "6 predictable entities reinitialized". It says this regardless of how many players are on the server, which makes sense, because other players are not predictable entities. I thought client-side prediction was only for the movement of the player. Are there other entities that the client can provide prediction for?
