• Prevent product key from being used on multiple virtual machines

  - by Nahum Litvin

  I have a software product. it will probably run on VMs that have no network connection at all. I want the user to pay for each VM the user runs. I thought to ask the user for some kind of hardware ID and provide him with serial that is unique for his machine. But user can just copy the VM image and than have two machines running? So I thought of having a security dongle. But how can I prevent user from running two VM's on the same machine both connected to the same dongle? This should be only basic defense so that actual hacking will be required to breach the license and not only spinning one more VM.

• What do you do when the code isn't complicated enough?

  - by Chris

  After six months of development on a project, our stakeholders have had a "gut check" and have decided that the path that we've been walking (a custom designed application framework and data access layer) is holding us (the developers) back from quickly developing the features they would like to see. After several days of debate management and the development team have decided to scrap the current incarnation and start over using ASP.net MVC, with Entity Framework as the bases of the a 'quick and dirty', lets just get it done project. In days following, our senior developer who has never worked with MVC or Entity Framework has finally gotten into a sample project and done some work. His take on ASP.net MVC, "this is not software engineering". So my question is this; what do you do, when one doesn't think the code is complicated enough?

• vlc 1.1.9 not working properly

  - by jaggib

  I have installed vlc 1.1.9 on wubi installed Ubuntu 11.04 using Ubuntu Software Center. Now when i tried playing videos in vlc (any format) full screen mode doesnt show controls and usually doesnt gets me out to window mode. it sometimes crashes to login screen. I tried the video output to 'X11 output mode' and 'XVideo output (XCB)' but the above problem persists and also bring another problem. full screen mode doesnt responds always when it does, it shows the video over the desktop instead of inside the player. the only way to get ubuntu to function normally is to restart the system. I tried with not using the 'Embed video in interface' but still the same problem. vlc runs perfectly well in windows. How can i make vlc function properly on my system or i need to install another player? My system config is: Graphics: VIA/S3G UniChrome Pro IGP Processor: AMD Sempron(tm) Processor 2800+ RAM: 1.5GB Motherboard Name: MS-7181 (MSI)

• RTOS experience

  - by Subbu

  I have been working as an embedded software engineer on mostly 8 bit micro-controller firmware and desktop/mobile applications development for the past five years. My work on a WinCE project (in which I got introduced to .NET CF) was short lived. I did use core APIs for interrupt processing, peripheral communication, etc...but again, not exactly a pure RTOS environment. In order to get together more solid experience for growing more in the embedded field, I want to work more with RTOSes. Will buying an evaluation board with an RTOS and putting together a project at home be regarded as a good experience or will an online course be more useful? I am just not clear as to what will be regarded as good experience. Any suggestions or directions will greatly help me. I have a passion for the field but just a need a point in the right direction.

• Developing Functional Specifications based on the UML Model

  A few days ago I found this white paper I did around 2004 way before I started really blogging:The Process OverviewUse-case to Specifications is a processing using UML use-cases to identify user requirements and model systems to be able to properly define functionality. This document is intended to serve as an execution based walk-through of this process.As background: The Unified Modeling Language (UML) is a language for specifying, visualizing, constructing, and documenting the artifacts of software...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• How to convince a non-technical client that their application spec needs to be simplified?

  - by Ryan

  Often times I am faced with the situation where a new client comes to me with an application that has literally 100s of unnecessary features and it is quite clear that things need to be drastically simplified for the project to have any chance of succeeding. How do you convince the client to take a more MVP approach and simplify? edit: So the current top answer is to provide the client with a time/cost estimate for the huge application. I'm not too fond of this answer because it doesn't address the real problem with this situation. And that is - it's a bad practice to spec out a massive application and then try and build it from the get go. I feel much more comfortable initially building a small, simple MVP foundation. And then adding small features to that foundation one by one. So how do I convince the client to approach building software in this way?

• Dealing with engineers that frequently leave their jobs

  - by ??? Shengyuan Lu

  My friend is a project manager for a software company. The most frustrating thing for him is that his engineers frequently leave their jobs. The company works hard to recruit new engineers, transfer projects, and keep a stable quality product. When people leave, it drives my friend crazy. These engineers are quite young and ambitious, and they want higher salaries and better positions. The big boss only thinks about it in financial terms, and his theory is that “three newbies are always better than one veteran” (which, as an experienced engineer, I know is wrong). My friend hates that theory. Any advice for him?

• I need advice on creating animal 3D walk cycles in XNA

  - by Zetar

  I want to purchase a number of 3D models from TurboSquid and animate them in an XNA game. I wrote a lot of games from 1985-1999 and have recently become involved with XNA. Now I would like to port one of my old games to the XBOX. I do have a background in 3D animation; but that was years ago. What is the current method for animating a walk cycle with a 3D model and using it inside XNA? Is there a book, software or a tutorial that you can recommend? Thanks in advance and sorry for such a broad and currently naive question.

• Python (v2.7) requires to install plugins to create media files of the following type: Vorbis encoder

  - by LibraryGeekAdam

  This is the message I get when I try to rip a cd from any player. I usually use the stock Rhythmbox but have tried others to no avail. I have just updated to 12.10 from 12.04 and I had no problems in 12.04. I have read the other posts and have switched to the Main Server in the Software Sources menu. I have installed Ubuntu Restricted Extras. Nothing seems to help. I would appreciate any help. "Python (v2.7) requires to install plugins to create media files of the following type: Vorbis encoder" Thanks!

• What is the Best Way to Incentivize a Team of Developers?

  - by Seth P.

  I know in advance that people are going to see this question and think "free Red Bull." But I am actually looking for the best way to tie rewards for developers to the company's long-term goals. For example, assuming a team is working on the same software product, would it be best to reward each developer based on the condition of the final product? They are a team after all, and this will ensure that they are all working towards the common goal of getting the product out. However, this ignores the fact that some developers are stronger than others and some work harder than others. In your experience, what is the best way to incentivize a team of developers?

• Better way to search for text in two columns

  - by David

  Here is the scenario. I am making a custom blogging software for my site. I am implementing a search feature. It's not very sophisticated - basically it just takes the search phrase entered and runs this query: $query="SELECT * FROM `blog` WHERE `title` LIKE '%$q%' OR `post` LIKE '%$q%'"; Which is meant to simply search the title and post body for the phrase entered. Is there a better way to do that, keeping in mind how long it would take to run the query on up to 100 rows, each with a post length of up to 1500 characters? I have considered using a LIMIT statement to (sometimes) restrict the number of rows that the query would examine. Good idea?

• Will learning programming be as fundamental as learning reading/writing to the kids of the future?

  - by pythagras

  It seems I encounter more and more economists, scientists, and miscellaneous other professionals that have jobs that involve programming on some level. More and more, the jobs that my peers have in many many technical professions involve at least some simple scripting if not something more involved. It seems it used to be that "software engineer" was a distinct profession, now its becoming just another skill like writing -- something that any serious technical professional should be able to use for their job. I see a future where programming is essential to getting any kind of technical/mathematical job. Extrapolating on my anecdotal view of my colleagues... Will the kids of the future become literate in programming in the same way they become readers/writers? Will it become so fundamental to our economy and society that it will be taught at an early age? Will interacting with computers be as important as interacting with other people?

• Questionable ethics regarding closed source softwares which are supposed to be open source.

  - by edem

  Several days ago I heard a sentence "Cracking company name routers are not a crime.". I asked "Why?" and the guy explained to me that company name used a linux distribution on their routers which source can not be closed because of their license but company name closed it. What do you think about this? Doing otherwise unethical "cracking" becomes ethical, or somewhat neutral if the software in question is "cracked" too? By "cracking" I don't mean breaking into a computer through someones' company name router but "cracking" my own router's OS which otherwise would be unethical.

• System response times --- A good Service Level Agreement?

  - by mpeterson

  In order to view system performance, I have been asked by management to give page response times for a few key pages. I want to make sure I am giving a good picture of the overall health of the system, and not just narrowing in on a single measurement. So my question is: When developing software, what metrics would you provide to your stakeholders to indicate a system that is healthy and running well? (if it is not running well, that should also be evident! Not trying to hide/obscure any problems.)

• What is the biggest weakness of students graduating with degrees in Computer Science?

  - by akobre01

  This question is directed more toward employers and graduate student advisors/professors but all opinions are welcome. What do you find is a common weakness of new hires and/or new grad students? Is it entirely variable dependent on the student and his or her university? Is there a particular skill or skillset that you wish new hires/researchers had expertise in and how can we remedey this deficiency? I realize that this question is general and really encapsulates two questions, one more about the weaknesses of new software engineers and one about the weaknesses of new researchers. However, both types of people tend to come from similar courses of study so I'm wondering if there is any overlap. Note: I am not a professor but I'm interested in how best to revise the undergraduate curriculum in CS.

• Should I concentrate on writing code for money or my studies while in college?

  - by A-Cube

  I am college student of Software Engineering. My worries are that while I am concentrating on my studies, my peers are getting down with the code (e.g. HTML, ASP, PHP, etc) to earn money. Should I be worried that I am not doing coding like them? I was asked to be Microsoft Student Partner but I refused because the person what was doing before me told it was just arranging events. Nothing as such like getting with Microsoft and coding. Should I be writing code and earning money as I still am in 4th semester? I only have C++ as learning language in college. Will my job count on these projects that I do, or should I concentrate on studies for now to get maximum benefit?

• Where do the responsibilities of build tools end and those of CI tools start?

  - by BrandonV

  In the delivery of software, and within the sense of the deployment pipeline, where do the responsibilities of build tools, like Maven, end, and the responsibilities of CI start? As a rough example of a problem that arises; should build tools have any responsibility to the configuration and execution of acceptance tests when they are further down the pipeline than actually building the artifact? I'd like an answer that addresses in the sense of deployment lifecycle phases rather than in specifics, like my example. Although examples would help bolster the answer.

• Java on Ubuntu server 12.04?

  - by Sean Dunwoody

  I'm a little confused at the moment. My back story in short, is that I'm trying to set up a Minecraft server on an Ubuntu server I've recently set up, obviously to do this I needed Java, but after googling for a short while I wasn't entirely sure whether it is possible (or legal?) to do so in Ubuntu 12.04 due to licensing type issues - so I installed open JDK instead which appears not to work properly with the Minecraft server software (I half expected this) I'm now considering uninstalling open JDK and instead trying to get proper Java on there instead, my question is, is this possible? Is it Legal? And if so how do I go about doing it? Because I'm finding it very difficult to find any instructions on how to do so for 12.04 . . .

• How do I download a corrupted package again?

  - by user64720

  Ubuntu 12.04 can't install Firefox 13 update, because the package is corrupted. While attempting to install, returns this error (I translated it from my language to English). /var/cache/apt/archives/firefox_13.0+build1-0ubuntu0.12.04.1_i386.deb W: Waited for dpkg --assert-multi-arch but was not there - dpkgGo (10: There are no "child" processes). I can tell that the package at /var/cache/apt/archives/firefox_13.0+build1-0ubuntu0.12.04.1_i386.deb is corrupted, but even as admin, I can't delete it in order to be downloaded again. How should I proceed? EDIT: There was a single package causing this conflict, please report here to understand all the situation: Why can't I install from software center?

• Magento not responding to payment gateway notifications fast enough or at all?

  - by robgt

  Some of our customers are getting to the confirmation of payment step in purchasing from our Magento store, and then they are getting a timeout error, where the SagePay payment gateway is trying to contact our server to tell it that a payment was successful (or not…) but it cannot contact our server, or cannot get a response from our server in a timely manner, and then the payment/order is being cancelled. I've raised this question to my hosting company, but all they told me was: "This is down to the way the software is configured on your server" This is currently a Magento 1.4.0.1 standard installation as far as payment gateways are concerned. What on earth could this statement mean? Is there some configuration that I need to do to make Magento listen to these requests and respond properly?

• Most Useful New Technology?

  - by Craig Ferguson

  I'm looking to take a sort of sabbatical, and I'd love to use it to learn a new technology. My question is this: What's the most useful "new" technology for a software engineer to use? Node.js, iOS programming, Android, something else? I'd prefer to stay away from anything too new or experimental, since those are, in my experience, rarely actually used in professional production environments (for better or worse). Does anyone happen to have stats on how many jobs there are for each new technology or have anecdotes about how fun each one is? I've been using python/Django, so that's out, and it's similar to Ruby so i don't think learning Ruby would be that useful to expanding my skills. Anyone have any other ideas?
