  • Keep getting messages about internal system errors

    - by Tomas Lycken
    I keep getting popups about internal system errors (see screenshot below) on irregular intervals (several times a day), that I don't know what to do about. If I continue through the dialog and try to report the error back to the Ubuntu project, I get a message stating that development on this version of Ubuntu has been completed, and that I should ask for help here if I don't know what to do about it. I don't. If I show the details of the error message, the "executable path" parameter shows /usr/share/apport/apport-gpu-error-intel.py. Is this a bug I should report to Launchpad, or just a configuration error somewhere? If it's a bug, how do I collect the data I (and the devs) need? Update in response to comment: I am running an ASUS N53SN, sporting an Intel Core i7 2630QM CPU and an NVidia GeForce 550M GPU.

  • Do support sites like stackoverflow upset the paid-support open source model?

    - by ajax81
    In order to stay relevant in the marketplace, I'm researching new business models for my software company. The open source model with paid support seems like a good fit for our product, but I have concerns about whether or not a paid support model is viable in an era where top-notch help is readily available for free on sites like those in the StackExchange network. Case in point -- I moved my employees to Ubuntu last year because I didn't want to pay for Win 7 licenses and new hardware (plus, the mono platform was highly attractive). My staff had no Linux experience, but were able to achieve relative competency in about 120 days with the help of AskUbuntu, StackOverflow, and a few "For Dummies" books. We did employ an Ubuntu consultant for 7 days to provide training and support, but beyond that spent $0.00 on any kind of paid expertise. In regards to my due diligence, I ran a 3 month beta of the freemium-paid-support model with one of our smaller customers, and achieved mediocre results. I'd like to think its because our software is so stable and easy to use that the customer didn't need much paid support, but I suspect that they circumvented the terms of our SLA in the same manner that we did with the move to Ubuntu. Does anyone out there has any thoughts, advice, or experience relevant to the move I'm considering? What worked, what didn't, etc? Thanks in advance!

  • What are approaches for analyzing the cost-benefits of a development methodology?

    - by Garrett Hall
    There are many development practices (TDD, continuous integration, cowboy-coding), principles (SOLID, layers of abstraction, KISS), and processes (RUP, Scrum, XP, Waterfall). I have learned you can't follow any of these blindly, but have to consider context and ROI (return on investment). My question is: How do you know whether you are getting a good ROI by following a particular methodology? Metrics, guesstimation, experience? Do analytical methods exist? Or is this just the million-dollar question in software engineering that has no answer?

  • How USB drives goes after system hard drives

    - by raihanchy
    I am using Ubuntu 12.04 LTS. My hard drives usually comes as: sda, with 'sudo blkid' and if I plug-in any USB drive, they comes as: sdb, sdc etc; after sda. That's fine!!! But problem arises after I restart my laptop with connecting those USB drives. They alter and comes first and hard drive goes to the end, like: 'sudo blkid' shows, sda, sdb for USB drives and sdc for hard drives. It's making problem to mount with /etc/fstab. I couldn't find any solutions for this. I would like to have any USB drives after my system hard drives, as in Windows. Please, help me at this point. Thanking you. Raihan

  • Japanese Multiplication simulation - is a program actually capable of improving calculation speed?

    - by jt0dd
    On SuperUser, I asked a (possibly silly) question about processors using mathematical shortcuts and would like to have a look at the possibility at the software application of that concept. I'd like to write a simulation of Japanese Multiplication to get benchmarks on large calculations utilizing the shortcut vs traditional CPU multiplication. I'm curious as to whether it makes sense to try this. My Question: I'd like to know whether or not a software math shortcut, as described above is actually a shortcut at all. This is a question of programming concept. By utilizing the simulation of Japanese Multiplication, is a program actually capable of improving calculation speed? Or am I doomed from the start? The answer to this question isn't required to determine whether or not the experiment will succeed, but rather whether or not it's logically possible for such a thing to occur in any program, using this concept as an example. My theory is that since addition is computed faster than multiplication, a simulation of Japanese multiplication may actually allow a program to multiply (large) numbers faster than the CPU arithmetic unit can. I think this would be a very interesting finding, if it proves to be true. If, in the multiplication of numbers of any immense size, the shortcut were to calculate the result via less instructions (or faster) than traditional ALU multiplication, I would consider the experiment a success.

  • Repairing or recreating a bootloader on a multi-booting EFI GPT system

    - by Emre
    Reinstalling Ubuntu messed up my boot loader so I I tried to fix it with boot repair. It detected my OSX installation and asked about removing the "separate boot/EFI". It also said my partition was full despite the fact that it wasn't and asked me to remove stuff. I declined both and proceeded. It's been stuck at the "purge and reinstall the GRUB" stage for half an hour. Is this typical, bearing in mind I have a fast SSD and CPU? Is there a better way to re-install grub on a multi-booting UEFI system? Does my pastebin provide any insight?

  • Should a project start with the client or the server?

    - by MadBurn
    Pretty simple question with a complex answer. Should a project start with the client or the server, and why? Where should a single programmer start a client/server project? What are the best practices and what are the reasons behind them? If you can't think of any, what reasons do you use to justify why you would choose to start one before the other? Personally, I'm asking this question because I'm finishing up specs for a project I will be doing for myself on the side for fun. But now that I'm finishing this phase, I'm wondering "ok, now where do I begin?" Since I've never done a project like this by myself, I'm not sure where I should start. In this project, my server will be doing all the heavy lifting and the client will just be sending updates, getting information from the server, and displaying it. But, I don't want that to sway the answer as I'm looking for more of an in depth and less specific answer that would apply to any project I begin in the future.

  • Making more complicated systems(entity-component-system model question)

    - by winch
    I'm using a model where entities are collections of components and components are just data. All the logic goes into systems which operate on components. Making basic systems(for Rendering and handling collision) was easy. But how do I do more compilcated systems? For example, in a CollisionSystem I can check if entity A collides with entity B. I have this code in CollisionSystem for checking if B damages A: if(collides(a, b)) { HealthComponent* hc = a->get<HealthComponent(); hc.reduceHealth(b->get<DamageComponent>()->getDamage()); But I feel that this code shouldn't belong to Collision system. Where should code like this be and which additional systems should I create to make this code generic?

  • What should happen at the start of a software project startup?

    - by Willem
    A quick introduction My college semesters include a 8 week project working for an actual company with a software need in order to get some much needed practical experience. I have just started such a project with 5 other students. We're required to spend roughly 40 hours a week per student on this project. We're working with SCRUM as the software development method, this was assigned by our teachers. The question Day one of the project just ended which has created some questions for me as to how to start a project in the 'real world'. Our first day included working on a project planning document (not sure what the English term is), creating a appointment with the company for an introduction and the opportunity to start specifying the requirements and setting up some standards for the behavior within the group. However these items didn't take that long to finish. We've made some concrete plans for tomorrow and the day after we'll meet the company. This still leaves several hours of 'work-time' unspent. Is it usual not being able to fill every hour of a day for work at the start of a project or are we simply too inexperienced to see what work needs to be done at this stage of a project, or are we, perhaps, going through the above list too fast? How does this work in the 'real world'? Do you spend your time wondering 'what should I do now', or do you have a clear view of what you're supposed to do at that moment?

  • How to shift development culture from tech fetish to focusing on simplicity and getting things done?

    - by Serge
    Looking for ways to switch team/individual culture from chasing latest fads, patterns, and all kinds of best practices to focusing on finding quickest and simplest solutions and shipping features. My definition of "tech fetish": Chasing latest fads, applying new technologies and best practices without considering product/project impact, focusing on micro optimization, creating platforms and frameworks instead of finding simple and quick ways to ship product features. Few examples of culture differences: From "Spent a day on trying to map database query with five complex joins in NHibernate" to "Wrote a SQL query and used DataReader to pull data in" From "Wrote super-fast JSON parser in C++" to "Used Python to parse JSON response and call C++ code" From "Let's use WCF because it supports all possible communication standards" to "REST is simple text-based format, let's stick with it and use simple HTTP handlers"

  • Where should you put constants and why?

    - by Tim Meyer
    In our mostly large applications, we usually have a only few locations for constants: One class for GUI and internal contstants (Tab Page titles, Group Box titles, calculation factors, enumerations) One class for database tables and columns (this part is generated code) plus readable names for them (manually assigned) One class for application messages (logging, message boxes etc) The constants are usually separated into different structs in those classes. In our C++ applications, the constants are only defined in the .h file and the values are assigned in the .cpp file. One of the advantages is that all strings etc are in one central place and everybody knows where to find them when something must be changed. This is especially something project managers seem to like as people come and go and this way everybody can change such trivial things without having to dig into the application's structure. Also, you can easily change the title of similar Group Boxes / Tab Pages etc at once. Another aspect is that you can just print that class and give it to a non-programmer who can check if the captions are intuitive, and if messages to the user are too detailed or too confusing etc. However, I see certain disadvantages: Every single class is tightly coupled to the constants classes Adding/Removing/Renaming/Moving a constant requires recompilation of at least 90% of the application (Note: Changing the value doesn't, at least for C++). In one of our C++ projects with 1500 classes, this means around 7 minutes of compilation time (using precompiled headers; without them it's around 50 minutes) plus around 10 minutes of linking against certain static libraries. Building a speed optimized release through the Visual Studio Compiler takes up to 3 hours. I don't know if the huge amount of class relations is the source but it might as well be. You get driven into temporarily hard-coding strings straight into code because you want to test something very quickly and don't want to wait 15 minutes just for that test (and probably every subsequent one). Everybody knows what happens to the "I will fix that later"-thoughts. Reusing a class in another project isn't always that easy (mainly due to other tight couplings, but the constants handling doesn't make it easier.) Where would you store constants like that? Also what arguments would you bring in order to convince your project manager that there are better concepts which also comply with the advantages listed above? Feel free to give a C++-specific or independent answer. PS: I know this question is kind of subjective but I honestly don't know of any better place than this site for this kind of question. Update on this project I have news on the compile time thing: Following Caleb's and gbjbaanb's posts, I split my constants file into several other files when I had time. I also eventually split my project into several libraries which was now possible much easier. Compiling this in release mode showed that the auto-generated file which contains the database definitions (table, column names and more - more than 8000 symbols) and builds up certain hashes caused the huge compile times in release mode. Deactivating MSVC's optimizer for the library which contains the DB constants now allowed us to reduce the total compile time of your Project (several applications) in release mode from up to 8 hours to less than one hour! We have yet to find out why MSVC has such a hard time optimizing these files, but for now this change relieves a lot of pressure as we no longer have to rely on nightly builds only. That fact - and other benefits, such as less tight coupling, better reuseability etc - also showed that spending time splitting up the "constants" wasn't such a bad idea after all ;-)

  • Plug-in based software design

    - by gekod
    I'm a software developer who is willing to improve his software design skills. I think software should not only work but have a solid and elegant design too to be reusable and extensive to later purposes. Now I'm in search of some help figuring out good practices for specific problems. Actually, I'm trying to find out how to design a piece of software that would be extensible via plug-ins. The questions I have are the following: Should plug-ins be able to access each others functionality? This would bring dependencies I guess. What should the main application offer to the plug-ins if I want to let's say develop a multimedia software which would play videos and music but which could later on get functionality added over plug-ins that would let's say be able to read video status (time, bps, ...) and display it. Would this mean that the player itself would have to be part of the main program and offer services to plug-ins to get such information or would there be a way to develop the player as a plug-in also but offer in some way the possibility to other plug-ins to interact with it? As you see, my questions are mainly for learning purposes as I strive to improve my software development skills. I hope to find help here and apologize if something is wrong with my question.

  • How can we reduce downtime at the end of an iteration?

    - by Anna Lear
    Where I work we practice scrum-driven agile with 3-week iterations. Yes, it'd be nice if the iterations were shorter, but changing that isn't an option at the moment. At the end of the iteration, I usually find that the last day goes very slowly. The actual work has already been completed and accepted. There are a couple meetings (the retrospective and the next iteration planning), but other than that not much is going on. What sort of techniques can we as a team use to maintain momentum through the last day? Should we address defects? Get an early start on the next iteration's work anyway? Something else?

  • Trying to find a recent - PHP book - that utilizes SOLID principles! [closed]

    - by darga33
    Pulling my hair out! I have heard of Martin Fowler's book PoEAA and the other book Head First OOA OOD but those are not in PHP. I desperately want to read them, but ONLY in PHP utilizing the - SOLID acronym - principles! Does anyone know of the absolute best, most recent PHP book that utilizes the SOLID principles and GRASP, and all the other best practices? I want to learn from the best possible source! Not beginner books! I already understand OOP. This seems like an almost impossible question to find the answer to and so I thought, hey, might as well post on stackexchange!! Surely someone out there must know!!!!!!!!!! Or if noone happens to know, Maybe they know of an open source application that utilizes these principles that is relatively small that is not a framework. Something that I can go through every single class, and spend time understanding the insides and outs of how the program was developed. Thanks so much in advance! I really really really really appreciate it! Well it looks like we aren't supposed to ask about best books, so nevermind this question! Sorry about that!

  • How to explain that writing universally cross-platform C++ code and shipping products for all OSes is not that easy?

    - by sharptooth
    Our company ships a range of desktop products for Windows and lots of Linux users complain on forums that we should have been written versions of our products for Linux years ago and the reason why we don't do that is we're a greedy corporation all our technical specialists are underqualified idiots Our average product is something like 3 million lines of C++ code. My and my colleagues analysis is the following: writing cross-platform C++ code is not that easy preparing a lot of distribution packages and maintaining them for all widespread versions of Linux takes time our estimate is that Linux market is something like 5-15% of all users and those users will likely not want to pay for our effort when this is brought up the response is again that we're greedy underqualified idiots and that when everything is done right all this is easy and painless. How reasonable are our evaluations of the fact that writing cross-platform code and maintaining numerous ditribution packages takes lots of effort? Where can we find some easy yet detailed analysis with real life stories that show beyond the shadow of a doubt what amount of effort exactly it takes?

  • How do you get past the Analysis to Paralysis when working on a new project?

    - by Cape Cod Gunny
    I've been struggling with how to get my project going. I've got an old software package that is in need of desparate rewrite. I haven't compiled the source code since 2004. It still sells, it's stable but does require the “Run this program in compatibility mode for:” on a lot of the newer windows systems. It's also one of those hard coded 640 X 480 screen resolution programs. Yuck! I can't seem to get started with this rewrite. I'm constantly fiddling around with different things. I'll play around with different fluid layouts for a while. Then I start looking around at how the main menu should work/look. I quickly find out that there's this thing called "Cool Bars" and I'll spend hours playing with that. Then I start thinking about stuff like "Oh I need to make sure that the screen sizes are preserved so when the application gets relaunched it remebers how the screens were positioned." Which leads to what happens if they have two monitors? Which leads to what happens if they have a quad screen? Yikes it's got to stop. I have always been a slow starter. I think about stuff long and hard up front. This has always plagued me. Once I get my mind made up then bam... I'm off and running. I'm looking for advice from some other one-person software companies that can help someone like me get off to a quicker start?

  • What's the difference between 'killall' and 'pkill'?

    - by jgbelacqua
    After using just plain kill <some_pid> on Unix systems for many years, I learned pkill from a younger Linux-savvy co-worker colleague1. I soon accepted the Linux-way, pgrep-ing and pkill-ing through many days and nights, through slow-downs and race conditions. This was all well and good. But now I see nothing but killall . How-to's seem to only mention killall, and I'm not sure if this is some kind of parallel development, or if killall is a successor to pkill, or something else. It seems to function as more targeted pkill, but I'm sure I'm missing something. Can an Ubuntu/Debian-savvy person explain when (or why) killall should be used, especially if it should be used in preference to pkill (when pkill often seems easier, because I can be sloppier with name matching, at least by default). 1 'colleague' is free upgrade from 'co-worker', so might as well.

  • It's hard to judge your own product. Is there a name for this issue?

    - by Epicmaster
    I was just talking to my partner about how hard it is to personally judge how good your product is after a while because you use it so often. You literally spend hours on your computer doing nothing but work on this Consumer Facing application, and you start to feel a little fatigue of using it over and over and over, at least a hundred times a day. You get scared this fatigue may mean the product you are building may have the same effect on the users and might mean you are doing something wrong. Is there a name for this in product development? For the fact that as a designer+ programmer+everything else, your product might not suck as much as you think simply because you spend way too much time with it, or a variation of this?

  • Techniques and methods to improve and speedup development

    - by Jlouro
    I just got a new project. It’s a WinForm app. And it’s interesting because I will have the possibility to learn how fish farms work and are managed. I will have to develop touch interfaces, and use datasnap to communicate and sync data between farm and office. The development will be done in DELPHI win32, still not sure about the database, but maybe SQLlite. So now comes the difficult part of the project, building it. I am just finishing one. It took me a lot of time to do it and I am a bit “burned out”. I will have time to relax, not much, but a few days. What I am looking is some tips and tricks and possibly tools to be able to speed up the development. It must be up and running in 2 months. So what tricks do you use to speed up things?

  • Loud fans despite cool system under Linux (but not Windows)

    - by Sman789
    My new desktop computer runs almost silently under Windows, but the fans seem to run on a constantly high setting under Linux. Psensor shows that the GPU (with NVidia drivers) is thirty-something degrees and the CPU is about the same, so it's not just down to Linux somehow being more processor-intensive. I've read that the BIOS controls the fans under Linux, which makes sense given the high fan speeds when in BIOS as well. It's under Windows, when the ASUS AI Suite 3 software seems to take control, that the system runs more quietly and only speeds the fans up when required. So is there a Linux app which offers a similar dynamic control of the fans, or a setting hidden somewhere in the ASUS BIOS which allows the same but regardless of the OS? EDIT - I've tried using lm-sensors and fancontrol, but pwmconfig tells me "There are no pwm-capable sensor modules installed". This is after the sensors-detect command does find an 'Intel digital thermal sensor', and despite the sensors working fine in apps like psensor. Help getting this to work would likely solve the problem.

  • As the current draft stands, what is the most significant change the "National Strategy for Trusted Identities in Cyberspace" will provoke?

    - by mfg
    A current draft of the "National Strategy for Trusted Identities in Cyberspace" has been posted by the Department of Homeland Security. This question is not asking about privacy or constitutionality, but about how this act will impact developers' business models and development strategies. When the post was made I was reminded of Jeff's November blog post regarding an internet driver's license. Whether that is a perfect model or not, both approaches are attempting to handle a shared problem (of both developers and end users): How do we establish an online identity? The question I ask here is, with respect to the various burdens that would be imposed on developers and users, what are some of the major, foreseeable implementation issues that will arise from the current U.S. Government's proposed solution? For a quick primer on the setup, jump to page 12 for infrastructure components, here are two stand-outs: An Identity Provider (IDP) is responsible for the processes associated with enrolling a subject, and establishing and maintaining the digital identity associated with an individual or NPE. These processes include identity vetting and proofing, as well as revocation, suspension, and recovery of the digital identity. The IDP is responsible for issuing a credential, the information object or device used during a transaction to provide evidence of the subject’s identity; it may also provide linkage to authority, roles, rights, privileges, and other attributes. The credential can be stored on an identity medium, which is a device or object (physical or virtual) used for storing one or more credentials, claims, or attributes related to a subject. Identity media are widely available in many formats, such as smart cards, security chips embedded in PCs, cell phones, software based certificates, and USB devices. Selection of the appropriate credential is implementation specific and dependent on the risk tolerance of the participating entities. Here are the first considered actionable components of the draft: Action 1: Designate a Federal Agency to Lead the Public/Private Sector Efforts Associated with Achieving the Goals of the Strategy Action 2: Develop a Shared, Comprehensive Public/Private Sector Implementation Plan Action 3:Accelerate the Expansion of Federal Services, Pilots, and Policies that Align with the Identity Ecosystem Action 4:Work Among the Public/Private Sectors to Implement Enhanced Privacy Protections Action 5:Coordinate the Development and Refinement of Risk Models and Interoperability Standards Action 6: Address the Liability Concerns of Service Providers and Individuals Action 7: Perform Outreach and Awareness Across all Stakeholders Action 8: Continue Collaborating in International Efforts Action 9: Identify Other Means to Drive Adoption of the Identity Ecosystem across the Nation
