• How can an application (like Firefox) be forced to use a certain network interface?

  - by Lekensteyn

  I've two interfaces: eth0 and wlan0 on a notebook. Possible use cases: eth0 grants me Internet access, and wlan0 is currently connected to a router which does not have Internet-connectivity. For development purposes, I need to connect to the wlan0 by default, but use eth0 for surfing eth0 and wlan0 are both connected to the Internet. For a torrent application, eth0 should be used for speed, but for portability of the notebook, SSH should have a connection over wlan0 eth0 is a wire connection, wlan0 is a wireless one. Sensible data should be transferred over eth0, but other traffic can go over wlan0 as well. Is there a way to force applications (like nc.traditional or firefox) to use a certain network interface? A wrapper like example-wrapper eth0 program is fine too if such program exist. It would be nice if it could configured within Firefox (in runtime). I'd like to avoid IPTables solutions if possible.

• Will the world depend less of developers?

  - by nmiranda

  Hi everybody, yesterday I had a little chat with a friend that is in the field of development as I am. And he told me that he planned to change of business, I mean, he wants to get off developing cause he doesn't think that it has future. "There will come days were you could have a job as a developer but you would never get rich" he said. "Nowadays is more important to have an idea and develop it in a product than being a software developer. Today you can find a lot of applications that can help you to make it. We have already non-sql databases, better cases than 10 years ago and other tools much of them free, everything is directed to depend less of developers and you'll see it more 10 years from now" Do you agree with that?

• programming can be taken as specialization - but what will I do still unclear [closed]

  - by C4CodeE4Exe

  I am bit confusing about my goals although whole motivation thing is $$$ but still there is something pushing me to pursue higher studies(being frustrated from boot-licking attitudes of peers and lottery system here in India for promotions,pay hikes and onshore opportunities). I am afraid I do not have any goals.I am software developer mainly in JAVA, but an ECE graduate.I want to work in programming languages. My problem is that I am not even Jack of all trades.I have experience in programming and thats where I am good(self-pro-claimed or atleast people say this treating them as a critics). I have decided to go with the wind and applying for programming languages as my specialization.But I know how to code,write test cases,how Perosnal and commercial IT insurances solution works.What I do not know is how to show that what I will do during my masters.I have no idea about what to showcase, how would my work ex will help me. totally oblivious thoughts... thanks waiting for replies....

• How to log frame times in an existing OpenGL game? [on hold]

  - by J Collins

  I have been using FRAPS for some time to benchmark instantaneous frame rates in an OpenGL game for which I am creating maps. Until recently it had been quite reliable. Now however, the bench marking shortcut has been unresponsive and I can't explain why. Ideally I could have a logging system automatically start logging whenever the game had focus, but can't find a good tool to do so. So option a) find out how to make FRAPS reliable again or b) find a new tool. Could one of you kind folks help me? Edit: Concise questions Is there a widely recognised tool to log frame drawing times and rates for compiled applications? If the answer is universally the FRAPs tool, are there any clear cases in which logging will not or should not be expected to work?

• Mimicking a bluetooth disconnection

  - by user2529672

  I've written a program to control a bluetooth device. I'm trying to test cases when the bluetooth disconnects, i.e. if its out of range. Physically taking the device out of range is one possibility, but its quite cumbersome and I have to go outside my office to achieve this. What can I do to trigger a disconnection? Is there, for example, an interferer I can setup, say with an Android phone, that would make the connection drop? Or limit the Bluetooth transmit power? Any other possibilities?

• Advice on Software Development

  - by user12514

  I am currently taking Business IT Foundation Degree course which involves SDLC and its my first year. I will be going out in the industry for the second year and I would just like to know some facts before launching out. I have been asked to create a system to enable the company to manage their staff and also to create a windows based system where users can register, view their details and so on. I am required to create: Several UML use case diagrams A conceptual class Diagram Test cases and test logs These have to been done for the windows based system. My concern is that I am not sure what a windows based system is and secondly I am having difficulties creating the diagrams as I am not familiar with them. Could anyone be kind enough to explain what they are and how I go about doing them please? Thank you.

• Does google see the output of document.write?

  - by merk

  I've got a site where people can list machinery for sale. Each item for sale has it's own dynamic page. On each of these pages we allow the person selling the item to have a link back to their own website. Some people only sell a handful of items and some people are selling dozens or hundreds of items. So in some cases we can have a 100 links back to their external site. Our SEO guy is saying this is bad (i'll open another question on that). So i was wondering if i take the links and spit them out using document.write, will that hide them from google and the other SE's ?

• Using "public" vars or attributes in class calls, functional approach

  - by marw

  I was always wondering about two things I tend to do in my little projects. Sometimes I will have this design: class FooClass ... self.foo = "it's a bar" self._do_some_stuff(self) def _do_some_stuff(self): print(self.foo) And sometimes this one: class FooClass2 ... self.do_some_stuff(foo="it's a bar") def do_some_stuff(self, foo): print(foo) Although I roughly understand the differences between functional and class approaches, I struggle with the design. For example, in FooClass the self.foo is always accessible as an attribute. If there are numerous calls to it, is that faster than making foo a local variable that is passed from method to method (like in FooClass2)? What happens in memory in both cases? If FooClass2 is preferred (ie. I don't need to access foo) and other attributes inside do not change their states (the class is executed once only and returns the result), should the code then be written as a series of functions in a module?

• Which language unifies OOP, both RPC call and Message passing a la Smalltalk, and more ...

  - by user310291

  I hate software editors who pretend to know better what you need and choose for you. Java and c# pretend multiple inheritance is dangerous. That I agree I often use Interface but in some cases I may need multiple inheritance : why not let me choose ? Also today you have to choose between RPC call à la Java and Message passing à la Objective C. Again can't I choose when one or the other is more practical ? So is there any language on earth which will free me from what I want to choose to use dependending on MY context and MY own judgement ?

• How can I convince a project manager that there is no way to solve all the compatibility issues?

  - by SAFAD

  I have been working on this project for more than a year now, and we are close to release, the project manager wants the product to be perfect and working in every single aspect. I like that and I love working under the perfection idea, but it seems he is delaying the launch too much because of compatibility issues, he wants the product to work in every single installation, every single configuration possible, and in most cases, the product just works without issues when it's on the hands of the client. UPDATE : yes the product doesn't work properly when there are conflicts, for example, other products that don't use guidelines nor standards to load libraries (causes double library load which leads to failure), cache is another example and so on..... but we warn the clients about the conflict before purchasing and help them fixing it after purchasing I've tried to explain it by giving some examples on major products, he understands the situation, but can not believe that it is near impossible (if it is not impossible) to do what he wants. Hope it is clarified enough for the community to answer.

• Avoid External Dependencies in SQL Server Triggers

  I sometimes want to perform auditing or other actions in a trigger based on some criteria. More specifically, there are a few cases that may warrant an e-mail; for example, if a web sale takes place that requires custom or overnight shipping and handling. It is tempting to just add code to the trigger that sends an e-mail when these criteria are met. But this can be problematic for two reasons: (1) your users are waiting for that processing to occur, and (2) if you can't send the e-mail, how do you decide whether or not to roll back the transaction, and how do you bring the problem to the attention of the administrator?

• @Microsoft: please provide universal and professional concepts

  - by Marko Apfel

  Why such constructs are included in the csproj-Files? <CodeAnalysisRuleSetDirectories>;c:\Program Files (x86)\Microsoft Visual Studio 10.0\Team Tools\Static Analysis Tools\\Rule Sets</CodeAnalysisRuleSetDirectories> <CodeAnalysisRuleDirectories>;c:\Program Files (x86)\Microsoft Visual Studio 10.0\Team Tools\Static Analysis Tools\FxCop\\Rules</CodeAnalysisRuleDirectories> So it every projects needs some manual steps to clean the project file so the solution could be build on a continuous integration server. That annoying! And also in a Visual Studio mixed editions team that’s too specific for the ultimate edition. As good as Visual Studio in most cases is, sometimes it is really far away from professional coding fundamentals and best practices.

• Compiz ( or even compositing in general) is not starting up when I login. Solution?

  - by ender.cc

  Whenever I log into a desktop environment, it doesn't seem that compositing is starting. Unity 2D works fine, but when I go to Unity 3D Compiz doesn't start up. I have to type compiz --replace & in terminal every time I login. Another example is when I log into a Cinnamon session, theming support is suddenly gone (although this may be a separate issue). If it helps im using the latest (295.40) NVIDIA drivers. EDIT: I am having exactly the same issue in both cases, upgrading from 11.10 and with a clean installation, in 32 and 64 bits. Related post.

• Hash Function Added To The PredicateEqualityComparer

  - by Paulo Morgado

  Sometime ago I wrote a predicate equality comparer to be used with LINQ’s Distinct operator. The Distinct operator uses an instance of an internal Set class to maintain the collection of distinct elements in the source collection which in turn checks the hash code of each element (by calling the GetHashCode method of the equality comparer) and only if there’s already an element with the same hash code in the collection calls the Equals method of the comparer to disambiguate. At the time I provided only the possibility to specify the comparison predicate, but, in some cases, comparing a hash code instead of calling the provided comparer predicate can be a significant performance improvement, I’ve added the possibility to had a hash function to the predicate equality comparer. You can get the updated code from the PauloMorgado.Linq project on CodePlex,

• What causes Google Analytics tags to work on some machines but not on others?

  - by Dallas

  The title of this question says it all. I am trying to update my code from the deprecated _getTracker() method to _createTracker(), but am experiencing inconsistent results. I have tried traditional and Asynch methods using a JSP include, but they all have the same result. My pageviews, and others in the office all show up in analytics. I have tried various test cases, but their visits are just not registering at all for them, but are showing up for me. The client has tried on multiple machines, and I have walked through with them step by step, so I know it's not just user error. I know that javascript being turned off will cause the tags not to work, but I am wondering if what else might cause the tags to not be recognized. I would appreciate any and all ideas.

• A look at an example of anti-spam algorithm

  - by pragmaticCamel

  What is a good approach to an anti-spam algorithm for a website similar to reddit? Their anti-spam algorithm seems awfully broken (banning on words in the title and doing a horrible job for that matter). Considering a post spam because it has the word 'spam' in the title is really not a wise choice. Anyway, how can one approach such problem ? Are there any tools that help in such cases? Also, what are the /technical/ reasons behind reddit's choice not using reCAPTCHA on every post submission? It seems like a much better solution than what they have right now. Since reddit is basically a community-driven website why not give such power to the communities' trusted members?

• When to use event.initMouseEvent for simulating mouse clicks?

  - by Protector one

  I wonder if there are benign use-cases for simulating mouse clicks using event.initMouseEvent. I found that it is used for creating pop-under ads in the following way: var e = document.createEvent('MouseEvents'); e.initMouseEvent('click', true, true, window, 0, 0, 0, 0, 0, true, false, false, true, 0, null); a.dispatchEvent(e); This code simulates a click on the opening browser window, to force the newly opened window beneath it. Evil. I'm thinking of simply preventing all simulated clicks in my own browser via a browser extension, but I wonder if I might break useful websites and behavior in the process. Therefore I wonder what situations justify simulating mouse clicks, and if there are big sites that use it in non-evil ways.

• What would be a good way to request comments?

  - by WarpEnterprises

  In the project/team I'm working the frequency of comments is a little low. One reason might be that it is not clear to the long-time devs what lines in the code really needs a comment (each part of the project has quite fixed devs). To increase this we plan to let team members review the code and check in "requests for comments", which the main dev of that part should replace with useful comments. Do you think this could work? If "yes": what tags should we use to mark? (e.g. //TODO please comment) Can you think of alternatives for this process? Edit: I appreciate your answers about best practice in commenting and writing code, and I completey agree. But my question targets the cases where refactoring is not an option (not wanting to change working code, not wanting to "accuse" main dev of producing code that needs refactoring,...) - so only more or better comments are an option (at least for this question).

• What are the pros and cons of Coffeescript?

  - by Philip

  Of course one big pro is the amount of syntactic sugar leading to shorter code in a lot of cases. On http://jashkenas.github.com/coffee-script/ there are impressive examples. On the other hand I have doubts that these examples represent code of complex real world applications. In my code for instance I never add functions to bare objects but rather to their prototypes. Moreover the prototype feature is hidden from the user, suggesting classical OOP rather than idiomatic Javascript. The array comprehension example would look in my code probably like this: cubes = $.map(list, math.cube); // which is 8 characters less using jQuery...
