  • Why changing signals causes NameErrors in a sane code? - PyGtk issue

    - by boywithaxe
    I'm working on a very simple app for Ubuntu. I've asked a question on stackoverflow, and it seems that the issue I am having is caused by signals, not by the scope of variables, as I originally thought. The problem I am having is that when TextBox emits a signal through activate the whole code works without a glitch. But when I change the signal to insert-at-click it returns NameErrors in every non-TextBox-linked function. Now, It is highly possible I am doing something completely wrong here, but is it at least probable that signals could affect global variable assignments?

  • Is a company order to switch to a certain IDE a red flag?

    - by Justin Alexander
    I recently joined a rapidly growing startup. In the past 3 months the development team has grown from 4 to 12. Until now they were very laissez-faire about what developers used to do their work. In fact one of the things I initially found attractive about the company is that most programmers used Linux, or whatever OS they felt best suited their efforts. Now orders, without discussion, have come down that everyone is to switch to Eclipse. A fine editor. I prefer SublimeText2, but it's just my personal taste. Is this a red flag? It seems capricious and unreasonably controlling to tell developers (non-MS) what IDE or tool-sets to use if they are already settled in and productive.

  • How to mock a dynamic object

    - by Daniel Cazzulino
    Someone asked me how to mock a dynamic object with Moq, which might be non-obvious. Given the following interface definition: public interface IProject { string Name { get; } dynamic Data { get; } } When you try to setup the mock for the dynamic property values, you get:   What’s important to realize is that a dynamic object is just a plain object, whose properties happen to be resolved at runtime. Kinda like reflection, if you will: all public properties of whatever object happens to be the instance, will be resolved just fine at runtime. Therefore, one way to mock this dynamic is to just create an anonymous type with the properties we want, and set the dynamic property to return that:...Read full article

  • Audiobooks for programmers?

    - by Zoot
    I'm a programmer with a two-hour round trip commute to work each day. I'd like to fill some of that time with audiobooks about software development. Any audiobooks that would help me become a better programmer would be appreciated. I'm thinking that books about design patterns and non-fiction about computing history might be good here, but I'm open to anything. Keeping in mind that I will be listening to this in a car, what are the best audiobooks that I can listen to? EDIT: Many people have also suggested podcasts. This is appreciated, but since podcasts arrive in a constantly arriving stream of data rather than as a finite amount of data, ways to juggle all of these different content streams would also be appreciated. To be more specific to my situation, my commuting vehicle has an MP3 CD player, USB input for MP3 files, and AUX input. I own Android and webOS devices that can be plugged into the AUX input.

  • Software requirements specification, please help!

    - by Nicholas Chow
    For a school project, I had to create a SRS for a "fictional" application. However they did not show us what it exactly entails, and were very vague with explanations. The SRS asked of us has to have at least 5 functional requirements, 5 non functional requirements and 1 constraint. Now I have tried my best to make one however I think there are still a lot of mistakes in it. Could you all please look at it and provide me with some feedback on which parts I can improve or just tell me which parts are plain out wrong and how to make it better? (The project has a maximum of 12 pages so it is a bit long, I will post it below. FR1 Registration of Organizer FR1 describes the registration of an Organizer on CrowdFundum FR1.1 The system shall display a registration form on the website. FR1.2 The system shall require a Name, Username, Document number passport/ID card, Address, Zip code, City, Email address, Telephone number, Bank account, Captcha code on the registration form when a user registers.

  • Using <= for every dependency in case of following semantic versioning idea

    - by zerkms
    As Semantic Versioning (and common sense) declares - the major version is incremented in case if non backward compatible change is introduced. Now let's assume we have a project called Project that has a current version 1.0.42 and a library Lib it depends on that is of a 2.1.3 version at the moment. Does that mean that following semver ideology we should constraint the dependency of the Project to be Depends: Lib (< 3)? From my experience - no one does that, but I find it semantically correct and very self-descriptive. What do you think of this?

  • Grub-Efi wrong resolution

    - by Nikki Kononov
    My question, as it comes from the title, related to grub, but it's a different thing. I re-installed Windows 7 and Ubuntu 12.10 in UEFI mode (before that I was using normal BIOS) and everything went perfectly fine. Both systems load as they should but there is one thing that keeps bothering me. The problem is before I installed both systems in UEFI I used to boot in both system using common grub (non-uefi) and resolution in this grub was correct (which is 1366x768). Right now with grub-efi I have wrong resolution (which is seems to be 640x480). So my question is can can I safely set grub-resolution using grub config files or issue is related to something else? (for instance graphics card). I am using Ubuntu 12.10 Intel HD 3000 + Nvidia GT 540M Optimus (I am using bumblebee) Kernel 3.5.0-19-generic all updates installed! I also added ubuntu x-swat ppa for drivers. Thank you for your help!

  • Who are the outspoken critics of Object-Oriented design?

    - by Xepoch
    Sure, object-oriented techniques are great and have stuck around for a while. I know only less than a handful of critics of the OO principles. It seems as though most non-OO designs and architectures are shunned, yet we continue to write a lot of good software in C and solve a lot of data changes via awk/sed and countless other examples. Correct tool for the correct job, yes? I'm having a hard time finding articles, presentations, or published criticisms of OO (even Fred Brooks has blessed information hiding). Are there any well-known, published and/or outspoken critics of OO?

  • Using C++11 for cross-platform Game Engine Development

    - by Samaursa
    Note: This is not a 'give your opinion' question about C++03 and C++11. Our game engine, written in C++03, is designed to be compiled on Windows, OSX and iOS. Linux support is planned for the (very) near future. Our experience is limited when it comes to consoles, which is why I am asking this question. Currently, we are debating whether switching to C++11 and using non-compatible features of the C++11 standard could pose a problem in the near future when we need to port our engine to any of the current gen consoles (perhaps the compilers supported by some console(s) do not support C++11 yet? We don't know...). So, game developers who have experience across multiple platforms and consoles, do you think we should stick to C++03 until the new generation of consoles arrive and most everybody has switched to C++11 standard (have they already?). Or are most consoles using/support compilers (VC++, GCC or variants?) that are already supporting C++11 features?

  • Ubuntu Server 12.04 + Wine + Filezilla FTP Server help

    - by Rebecca Joy
    I am not very experienced with non-windows operating systems, so please if you can answer, consider me to be a complete newbie with this. I have a Ubuntu Server 12.04, I installed Wine on it so I could install some familiar programs with GUI on my Ubuntu. I installed Filezilla Server using Wine, that went fine, the server is running, but I cannot find the GUI anywhere. I know it is running because in the winefile, if I execute the filezille server.exe, it says it is already running. However I have not been able to configure anything on the filezilla server because I can't see it anywhere. What am I missing?

  • Something confusing about Single Responsibility Principle

    - by user1483278
    1) In fact if two responsibilities are always expected to change at the same time you arguably should not separate them into different classes as this would lead, to quote Martin, to a "smell of Needless Complexity". The same is the case for responsibilities that never change - the behavior is invariant, and there is no need to split it. I assume even if non-related responsibilities are always expected to change for the same reason ( or if they never change ), we still shouldn't put them in the same class, since this would still violate high cohesion principle? 2) I've found two quite different definitions for SRP: Single Responsibility Principle says that a subsystem, module, class, or even a function, should not have more than one reason to change. and There should never be more than one reason for a class to change Doesn't the latter definition narrow SRP to a class level? If so, isn't first quote wrong by claiming that SRP can also be applied at subsystem, module and function levels? thank you

  • Getting work done in a small office

    - by three-cups
    I work in an office area of ~450sqft. There are a total of 7 people working in the office. I've been finding it hard to concentrate on my work (writing code) because of the distractions going on around me. The distractions are both work-related and non-work-related conversations. I'm trying to figure out what to do in this situation. I want to be part of the team, and I want to get my work done to the best of my ability. I can easily think of two options that I don't like: Stay where I am, not be able to concentrate and get less work done Move somewhere else. (This is tough because I code on a desktop, so I'm not very mobile.) But what are other options? I'm going to talk this through with my team in the next couple days. Any advice or solutions would be great.

  • Would learning any (linguistic) language imparticular further your programming career?

    - by Anonymous
    It seems apparent that English is the dominant international language for programming (in the West, at least!) based on previous P.SE questions. Or maybe not, given that a highly upvoted comment correctly points out that asking a question like that on a predominantly English site will skew the results. This question is about whether there is a benefit in learning a foreign language for software development. For example, do the Chinese have completely different software tools, langugages, technologies etc? How about Japanese, Russian, and other non-latin based languages? Am I/are we missing an entire world of software development languages, tools and so on that only exist in these other languages? Or do people that know these languages still learn and program using the tools and languages we all know and love?

  • Replace Broadcom "wl" driver with "b43"

    I'm using Ubuntu 10.04.4 LTS, and in my laptop there is a Broadcom BCM4312 wlan card. lspci output: 04:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01) Subsystem: Broadcom Corporation Device 04b5 Flags: bus master, fast devsel, latency 0, IRQ 18 Memory at f4500000 (64-bit, non-prefetchable) [size=16K] Capabilities: [40] Power Management version 3 Capabilities: [58] Vendor Specific Information Capabilities: [e8] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable- Capabilities: [d0] Express Endpoint, MSI 00 Capabilities: [100] Advanced Error Reporting Capabilities: [13c] Virtual Channel Capabilities: [160] Device Serial Number 81-ac-1d-ff-ff-12-54-92 Capabilities: [16c] Power Budgeting Kernel driver in use: wl Kernel modules: wl, ssb So as you can see, the current (and default) driver is wl - installed with jockey. But I have another Ubuntu based distribution on my laptop (BackTrack linux), which is also 10.04, but it has the b43 driver installed and the overall performance is MUCH better. So I would like to install it on this OS too, but even google didn't help me. So my question is how to install the latest b43 driver on my Ubuntu?

  • Should companies require developers to credit code they didn't write?

    - by sunpech
    In academia, it's considered cheating if a student copies code/work from someone/somewhere else without giving credit, and tries to pass it off as his/her own. Should companies make it a requirement for developers to properly credit all non-trivial code and work that they did not produce themselves? Is it useful to do so, or is it simply overkill? I understand there are various free licenses out there, but if I find stuff I like and actually use, I really feel compelled to give credit via comment in code even if it's not required by the license (or lack thereof one).

  • How does the web server choose between unicode and utf-8 for accented characters?

    - by jacques
    I have a web server with my ISP which replaces accented characters in URLs with their unicode values: for instance é (eacute) is translated to %e9 (dec 233). For testing locally I use EasyPHP which translates those characters by their utf-8 equivalence: é is then replaced by the well known sequence %c3%a9 (é)... Browsers served by EasyPHP don't decode unicode values but they do if running locally (utf-8 and non converted accent also)... I have been unable to find where this behavior is configured in the server. This is a problem as some urls are built by my application using the php rawurlencode() which seems to always encode with unicode values on both servers. Any idea?

  • How do engines avoid "Phase Lock" (multiple objects in same location) in a Physics Engine?

    - by C0M37
    Let me explain Phase Lock first: When two objects of non zero mass occupy the same space but have zero energy (no velocity). Do they bump forever with zero velocity resolution vectors or do they just stay locked together until an outside force interacts? In my home brewed engine, I realized that if I loaded a character into a tree and moved them, they would signal a collision and hop back to their original spot. I suppose I could fix this by implementing impulses in the event of a collision instead of just jumping back to the last spot I was in (my implementation kind of sucks). But while I make my engine more robust, I'm just curious on how most other physics engines handle this case. Do objects that start in the same spot with no movement speed just shoot out from each other in a random direction? Or do they sit there until something happens? Which option is generally the best approach?

    With a brand new install of 12.04 on my Dell Inspiron M5030, Unity 3D appears to load everything but the icons in the top left, and I am unable to click on anything. Unity 2D seems to works fine however. I have done nothing except install Synaptic Package manager and follow this guide to install FGLRX Drivers under Settings ? Additional Drivers, the driver shows as installed and functioning. Also after running: /usr/lib/nux/unity_support_test -p, I get this: OpenGL vendor string: ATI Technologies Inc.

  • Do Not Uninstall Flag on Apt?

    - by Daniel C. Sobral
    Does the Debian/Ubuntu package infrastructure has some way of marking packages so that they never get uninstalled, no matter the pinning of other packages? My problem is that, sometimes, packages installed by Puppet (coming from non-standard repositories, of course) cause other packages to get uninstalled -- in particular, openssh-{server,client}. The way this happens is that package A and B depend on different versions of package C. If A is installed and one asks to install B, then the version of C changes. The new version of C is incompatible with A, so A gets uninstalled. The funny thing is that the process is then reversed, as, on the next run, Puppet notices that A is not installed and tries to install it. So, basically, I want to make sure A never gets uninstalled, which would prevent B from getting installed. That would be reported as an error, making me aware of the issue. If anyone cares, Puppet uses the following command to install packages: /usr/bin/apt-get -q -y -o DPkg::Options::=--force-confold install <package>

  • Working with CPU cycles in Gameboy Advance

    - by Preston Sexton
    I am working on an GBA emulator and stuck at implementing CPU cycles. I just know the basic knowledge about it, each instruction of ARM and THUMB mode as each different set of cycles for each instructions. Currently I am simply saying every ARM instructions cost 4 cycles and THUMB instructions cost 2 cycles. But how do you implement it like the CPU documentation says? Does instruction cycles vary depending on which section of the memory it's currently accessing to? http://nocash.emubase.de/gbatek.htm#cpuinstructioncycletimes According to the above specification, it says different memory areas have different waitstates but I don't know what it exactly mean. Furthermore, what are Non-sequential cycle, Sequential cycle, Internal Cycle, Coprocessor Cycle for? I saw in some GBA source code that they are using PC to figure out how many cycles each instruction takes to complete, but how are they doing it?
