Open source Definition and 55 Threads

The summary says it all, really, but in addition, I've done a lot of googling and am finding it hard to identify trustworthy options. LibreCrypt, DiskCryptor and VeraCrypt are candidates, but I have not used any of these tools so am wary of jumping in and finding that I have bricked my PC.

I am hoping this forum may be a good page for this question. Not sure where else to post. I have been asked if I can write a user GUI to control a system that we build--the system is made with the fairly common electronics board designs and PIC MPs and presently is controlled from a...

I am thinking of doing a DIY project in which one sub-task would be to dynamically balance a small assembly that will be spun up by, for example, a small motor taken from a DVD drive. As a test case, here is a setup where we would like to adjust screws S1 to S6 such that the cylinder is...

TL:DR; I've started an open source C# physics library: University Physics The Long Version So it turns out there's relatively little in the way of full physics libraries written in C# (the best I can find is bepuphysics which seems to be focused only on classical mechanics). With this...

Are there any folks here who use open source alternatives to Matlab and Mathmatica for visualization of quantum mechanics? Also, are you aware of any introductory quantum material for that tool? If not, do you think such a thing would be worthwhile for visual leaners? Why or why not? I have...

I don't usually need help in locating software, but I'm having a heck of a time tracking down a good open-source bit of software which solves integer programming problems using arbitrary precision! If I don't find one soon, I'll need to write it myself. Which I don't mind, but it's silly to...

Hi, I'm looking for open source projects to contribute to to build my resume and computer programming portfolio to hopefully land a computer-related job. What are good open source projects that I can contribute to?

I want to start a project that requires parallel code for adaptive mesh refinement. I don't want to re-invent the wheel, and was hoping to leverage an open source library as a starting point. Does anyone have experience with any of these codes and could make a recommendation? At this point I...

I have two questions on this topic: 1- What is the difference between free and open source software? Do both mean the same thing? 2- Some free (open source?) software is used by companies to make big money. Aren't these conflicting things?

To all who are interested in a source for the treatment of partial differential equations: Victor Ivrii, Toronto, Course notes, 310 pages https://www.ams.org/open-math-notes/omn-view-listing?listingId=110703&utm_content=buffer2458a&utm_medium=social&utm_source=facebook.com&utm_campaign=buffer

Does anyone know if there is an open source (or relatively inexpensive) software that is roughly equivalent to PV calc. Specifically that uses ASME formulas to calculate MAWP or vacuum ratings on a vessel?

Does anyone know what the open source code is called that hysys was built on so I can file a freedom of information act paper work. I would also like to do this for NEC-2 for antenna radiation modeling.

I wonder how can scientists trust closed source programs/softwares. How can they be sure there aren't bugs that return a wrong output every now and then? Assuming they use some kind of extensive tests that figures out whether the program behaves as it should, how can they be sure that the...

Hello everyone. I am a computer science and applied math double major. I want to get involved in an open source project so I can gain experience and so I have something to show potential employers that I worked on. I just created a GITHUB account and I am not an expert at using it, nor have I...

Hi! I'm would like to ask if there's any open source available for FE/Fluid analysis? I'm planning to use it to simulate icing and melting process in a ice storage based on different geometry.Its something like a fridge with coolant ect. I would like to simulate the icing and melting process...

Okay, so I'm new to this forum, but I'm hoping I can get some help. I live in the United States, and I'm having trouble converting from metric to standard with the build plans given. I want to build the open source Spaceframe recumbent bike which the build plans can be found...

I am wondering why we aren't replacing politicians (such as presidents of countries) by open source programs. Programmers would program several different programs and people would vote for them. To be eligible the program must pass through thousands/millions of different situations (like the...

hey! I want to contribute to the open source but i am unable to know the exact way, how and where should I do that. If anyone can help?

Hi everyone. I'm working on getting together some notes on school maths and of course I'd like to include some diagrams. The usual stuff, graphs of things like parabolas, circle geometry, etc. But I'm also skint. So I'm looking for some open source programs that can do that, and they need to be...

I found some open source code in wx that I'm considering re-writing in qt and adding some new functionality to. It's for science research. Before I do, I wanted some feedback from the community if this is a worth while endeavor and an estimate of how long it would take. It's about 700 lines...

Hey all, I'm working on the JUICE mission (Jupiter Icy Moons Explorer) and I've been tasked with finding software (preferably open source, but paid is fine) that can optimize circuit network designs that I upload. Originally I was trying to find programs that would run optimization using the...

I have looked around for a group of people who perform cancer research as a kind of open /crowd sourced project. Not paid researchers, but a group of people passionate about science and finding a cure. I have found some resources for this kind of research through organizations like COSMIC but no...

Very interesting bunch of guys trying to get a man into suborbit as cheap as possible. Found their website and youtube videos links at the bottom. Thought I would share. They have interesting video's of engine tests as they try to design the first rocket to send a man into space...

Any favorites guys? And have you developed any source code personally?

Hi guys, I'm trying to compile an open source program (chess and chess variant engine) under linux but for some reason it doesn't work. I know almost nothing regarding programming so I don't know how to fix the problem. In a chess server I asked some programmers if they knew how to fix the...

Is there an open source math software for Mac OS X which is equivalent to Mathematica? I intend to use it for vector geometry problems (drawing planes, lines in 3-D space).

Hi folks, the subject line says it. I'm currently using geogebra as a note book in which to write "memory cards" in latex. You know the sort of thing: when you learn a new formula and want to keep it in virtual "card" form. I love Sticky Notes, but I can't get latex on to them. does anyone...

learning C++ by reading the code of open source projects? Is there any resource that teaches C++ by taking an open source project (at the level of quake 3 for example)and explains the code step by step for some one who only knows the very basics . In my opinion It will be very efficient . I can...

Hello all. I need some advice for my programming skills. Now I'm a third year student majoring electronics and information technology(not sure what to specialize). Everything i study at the school is real basics things such as maths, physics, and all the experiments etc. .I am sure they are...

Hi all, I hear all this talk about how open source is awesome and how software should be free and accessible to anyone. While I do enjoy gaining access to free software and whatnot, I can't help but wonder, how do software developers actually make money if the open source thing catches on...

Mathematica/Maple/Matlab are awesome and they use algorithms which make computations faster, but they are proprietary and closed source. wxMaxima and Sage Math exist, and I need to enter this developer community. But its mostly composed of uber-jargon that I'm not yet easy with. I haven't...

Hello, after having used Scilab for the longer part of a while by now, I'm looking to change over to a functionally more enhanced software but am not yet sure which to choose. I've more or less come down to a choice of four programs, of which I would like you to pick the one which you think is...

Just how does industry rely on open source ware? This probably depends on the industry of course. I ask this because there is a lot of neat open source stuff-- I am looking in the direction of finite element. I really would like to learn a FEM and FEA program. Should I learn an open source...

Dear Friends, Do some one know whether there is some open source Mathematics software available like Mathematica/Maple or Matlab.

I am just using MathCad as an example, as I don't know others. In college I did use something that did good 3D plots, and solved differential equations and performed integration. I was wondering if there were free or low-cost alternatives to these expensive programs. I just need something...

As in, alternatives to programs such as AutoCAD, Solidworks, etc.

hi there, I been on google and ask.com for long time i still couldn't find the answer to "What are the differences between the open source paradigm and the traditional software development?"i tried "Open source paradigm" and "traditional software development model". i read through but it didnt...
