• What's typical in terms of royalties? [closed]

  - by Matt Phillips

  I'm a developer negotiating compensation for a commercialized version of some data analysis software I wrote (see my profile if you like). This is a completely new experience for me. I want per-unit royalties, but I don't have the slightest idea what the standard amount is. I also want to be compensated for my time, so that's an upfront R&D cost for the company I'm negotiating with, but distribution cost to them is presumably virtually nothing once it's out there. But then there's support costs. What sorts of deals have you folks negotiated?

• Global Day of Coderetreat

  - by Tori Wieldt

  From the coderetreat.org website: Coderetreat is a day-long, intensive practice event, focusing on the fundamentals of software development and design. By providing developers the opportunity to take part in focused practice away from the pressures of 'getting things done', the coderetreat format has proven itself to be a highly effective means of skill improvement. This year, the Global Day of Coderetreat is happening on December 8. It sounds cool and fun, and of course, Java Champions and Java developers around the world are involved. Here's a small sampling: Chennai, India São Paulo, Brazil Skopje, Macedonia Kraków, Poland You can go to http://globalday.coderetreat.org/  to look up events near you. It's a great opportunity to practice your craft. Here's a video from an event last year to get a flavor:

• Are there compatibility issues opening Visual Studio Professional projects in Visual Studio Express, and vice versa? [migrated]

  - by theGreenCabbage

  Disclaimer: I have taken a look at the 50+ StackExchange forums to find the right place, and it seems /Programmers/ is the most suitable Exchange for this. If this is the wrong place to ask this, however, please let me know - I will personally delete the thread. I am in the process of downloading a single license for Visual Studio 2013 for my firm of 2-3 developers. One license is approximately $498.00 USD. As a small firm, our funds are short, but since we will be creating commercial software, we decided we will be needing the features of the Professional edition. At the same time, our decision is to use the Express edition for the rest of the two developers. My question is - will there be compatibility issues between Express projects and Professional projects for Visual Studio?

• Is Adobe Flash 11.2 working with Nvidia hardware again in 12.04?

  - by Oranges

  I installed the newest Nvidia-Linux drivers version number 304.43 on 12.04 installation and all Flash Videos now show me "accelerated video rendering". Previous Nvidia drivers + Adobe Flash only rendered in software, at least since Adobe officially said they turned off "hardware acceleration" for Linux, because of unstable and unsecure drivers. Has this changed? Is hardware acceleration really back? Can anyone verify this as well? The Nvidia driver 304.43 patch notes said: Fixed a bug that caused VDPAU to hang when expanding the YouTube Flash Player. Hardware: Nvidia 8600M GT

• Why is 2^16 a "special" number?

  - by javamonkey79

  OK, I feel stupid asking this - but in Jeff's article: Getting the Interview Phone Screen Right and originally stated in the 5 essential phone screen questions: They shouldn't stare blankly at you when you ask with 2^16 is. It's a special number. They should know it. I've been a developer\software engineer\code monkey\whatever for a little while now, and I don't think I've ever come across this. I mean, I can certainly count binary values do basic operations on them, etc, etc. But I don't see what is "special" about this value.

• How can I keep track of all the websites I've made like a proper business would?

  - by Mile

  A few other students and I are forming a group that wants to become good at what we do: websites. We are making websites for free for friends at the moment in order to get ourselves some experience and to learn from each other. We are about to finish our first website this week. In 6 months time we plan to have a portfolio and hope to start charging for websites. The issue is that we are all beginners and we are unsure about how to keep records of the websites we do. It is important as we may want to maintain a few websites or add to them later on. How does a proper web design business keep records of all info needed? Is there a program or software package we can use?

• Microsoft Build 1st Day

  - by Dave Noderer

  Great keynote and I don’t like keynotes.. Seeing the great breadth of large and small devices and the number of manufacturers along with the software vision for Windows 8 and Windows Phone 8 was inspiring. Jordan Rudess demonstrates Tachyon on Windows 8 Then he played for a while too..   I especially liked Steve Balmers 82” slate!! Can I have one!   And best of all, they finally released the Windows Phone 8 SDK. http://www.microsoft.com/en-us/download/details.aspx?id=35471 Off to sessions…   Stay tuned for more!

• Is ROA a specific form of doing SOA?

  - by JohnDoDo

  I have read somewhere that ROA (Resource Oriented Architecture) is SOA (Service Oriented Architecture) with specific constraints added. SOA is the abstract concept of combining discrete pieces of software and ROA is an implementation of SOA with all of the constraints of RESTful services applied to it: SOA = the concept ROA = the concept + specific implementation details I also had my share of posts saying that ROA is different than SOA, then simply fallback to statements like "ROA is REST" and "SOA is SOAP" and presenting the same more or less pertinent comparisons and differences between SOAP and REST. So just to clear up my confusion: Is ROA a specific form of doing SOA?

• How is Basic Physics applied in CS/SE?

  - by Wulf

  What basic physics principles do software engineers and/or computer scientists use to help solve specific or common problems? The first one that came to my head was creating a Physics engine for a game; physics is involved, as it requires knowledge of: Forces and Motion: Kinematics, Dynamics, Circular Motion However, I need another example, but haven't come across one that involves basic physics. Please consider the following basic physics (grade 12 level) concepts: Energy and Momentum: Work and Energy, Momentum and Collisions, Gravitational and Celestial Mechanics Electric, Gravitational & Magnetic Field: Electric Charges and Electric Field, Magnetic Fields and Electomagnetism The Wave Nature of Light: Waves and Light, Wave Effects of Light Matter-Energy Interface: Einstein’s Special Theory of Relativity, Waves, Photons and Matter, Radioactivity and Elementary Particles I will be happy with any response; Keywords for google, names of methods like raycasting, etc.

• How to render Minecraft on the GPU?

  - by l0b0

  Hardware: Intel i7 AMD Radeon HD 6970 SSD with plenty of space 6 GB RAM Software OpenJDK 6, 7, and Oracle Java 7 (reproducible with all three) AMD Catalyst 12.8 and open source driver (reproducible with both) Ubuntu 12.04 x86_64 and older Minecraft 1.3.2 vanilla and older On this setup I am getting rubbish frame rates after a short while of playing, dropping from about 45-55 to 15 in a couple of minutes. CPU use is 40-45 even when rendering the opening screen at 1920x1280, and gameRenderer is using about 90% CPU when playing. Rather than trying to eke out a few more FPS out of an obviously broken rendering pipeline, I really hope to find a solution to make the GPU render Minecraft.

• Bluetooth Audio and SoftPhone Audio Input/Output

  - by o7th Web Design

  I have a Voip Softphone software that I would like to start using on my Ubuntu 14.04 box. Here's the thing. My system sound right now goes through my HDMI to my speaker system so I can play music all day ;-) I have a bluetooth headset connected to the machine as well. What I am wondering is if there is a way to: Auto-mute the music when a call comes in Auto-switch the sound devices when a call comes in, from my hdmi sound device, to my headset Auto-switch back when the call ends, and auto-un-mute the music Or even just an auto-switch to the headset? I can always pause the music ;)

• If I intend to use Hadoop is there a difference in 12.04 LTS 64 Desktop and Server?

  - by Charles Daringer

  Sorry for such a Newbie Question, but I'm looking at installing M3 edition of MapR the requirements are at this link: http://www.mapr.com/doc/display/MapR/Requirements+for+Installation And my question is this, is the Desktop Kernel 64 for 12.04 LTS adequate or the "same" as the Server version of the product? If I'm setting up a lab to attempt to install a home cluster environment should I start with the Server or Dual Boot that distribution? My assumption is that the two are the same. That I can add any additional software to the 64 as needed. Can anyone elaborate on this? Have I missed something obvious?

• When is using stdio preferable to fstream?

  - by Karl Bielefeldt

  I work on a well-established, embedded C++ code base. We have been using a proprietary API to our filesystem. For better integration with third-party C libraries, we are currently in the process of implementing most of stdio.h and fcntl.h. I made what I thought was a non-controversial proposal that we should also implement the fstream class and encourage new C++ code to use it instead of the new (to our code base) C-style API. We already have the stdout parts of iostream available, although it is not widely used. Given a choice between using stdio and fstream, what are good reasons to choose stdio for embedded software development in C++?

• Effective way of keeping past projects with their working development environment?

  - by Korey Hinton

  I find that whenever I want to go run a past project, it will take a long time before I can find it and before I have everything set-up again for it to be able to run. For example, I have python projects I created in Linux, and it depends on software packages that are easily installed in Linux, yet I no longer have the Linux VM I was using. And some of my other projects depend on other variables like web server configuration, PATH variables, sdk, IDE, OS version, device, etc. Does someone have an effective way of handling this issue? As of now I have only concerned myself with keeping the source code backed up yet it is difficult re-establish the working development environment and it is also difficult to keep the working development environment around as well.

• DrRacket icon doesnt work?

  I installed DrRacket from the Ubuntu Software Center. All went well and an icon appeared however nothing happened when I clicked the icon so I removed it. Then went to the Developer website and downloaded full-5.3.0.21-bin-x86_64-linux-debian-squeeze.sh. I installed this via Terminal with sudo apt-get install racket. The DrRacket icon came back in Dash Home but again clicking it nothing appears to happen. How do I start DrRacket? I am running Ubuntu 12.04 LTS dual boot on a 64 bit Dell

• Gmail Now Searches Inside PDF, Word, and PowerPoint Attachments

  - by Jason Fitzpatrick

  Gmail has long had a robust system for searching within the subjects and bodies of your emails, now you can search inside select attachments–PDF, Word, and PowerPoint attachments are all searchable. Prior to this update, Gmail could search inside of HTML attachments but lacked more advanced attachment querying abilities. Now when you search your Gmail account you’ll see search results for not only the subject and body contents but also the contents of popular formats like PDF and Word documents. Don’t forget to take advantage of advanced search terms to speed up your query. If you know the information you need is in an attachment but can’t remember which email, include “has:attachment” in your search to only peek inside emails with attachments.

• Microsoft Office 2013 Takes New Approach

  You can check out an article from Computerworld for a good look at the questions and answers about the new software. For instance, you've probably noticed that I'm not giving the full name. That's because Microsoft seems to be using several names. If you go the traditional route and pay the one-time upfront fee for the shrink-wrapped edition, it's Office 2013. There's also a tablet version called Office Home and Student 2013 RT - but that won't include the iPad, or at least not at first. The consumer preview, which I'll be linking to in a minute, is dubbed Office 365 Home Premium. There ...

• How do you deal with the details when reading code?

  - by upton

  After reading some projects, I find that it is not the architecture of the software that is really hard to know. It is not hard to figure out the architecture immediately if the project is clearly designed and implemented, if it's hard and never seen before, some day later I can find out some pattern similar to the one I read in the same domain. The difficulty is that the concepts and mechanism defined by the author are really hard to guess, and these concepts may spread in the whole project which makes it hard to grasp. The situation is normal and universal and you can ask questions to your colleague when in a company. However, it gets worse if nobody around you knows these details. How do you handle these details which block your reading?

• Finding Internship Opportunities

  - by mbreedlove

  I am a senior in high school majoring in Computer Science next fall. This summer, I would like to intern at a company relevant to my interests of investment banking and software engineering. What would be some possible ways to find openings? How should I contact them? (E-mail, phone, etc.) Should I prepare and submit a CV? I feel it might be a little dull as it would have no experience or references. After contacting someone about an internship, should I follow up, or just wait for them to contact me? Is there anything else I should do or be aware of?
