Free Scientific Software for Developing World?

FlashBoltzmann asks: "I'm a physics student in the US working with a group of physicists, mostly from Africa, who are interested in helping their colleagues on the continent obtain free software for scientific and educational use. Often, many science departments in Africa have little or almost nonexistent funding to purchase new software packages, especially for scientific research or education. Some know of the free software available but say it takes up large amounts of time over often slow internet connections to find and obtain it. I am asking for any recommendations on freeware or open source software, for any operating system, that anyone knows about. We are looking at the Debian version of Linux for a lot of the great software that comes with it but resources for MS Windows would be helpful as well."

"Free educational software of any level is appreciated though we prefer college and graduate level software. Also, field specific software is great, e.g. software for condensed matter physics. Eventually we'll probably combine the software on CDs to be distributed to these scientists. Any help is appreciated especially with programs that perform simulations, mathematical and statistical analysis and plotting, compilers, lab software, etc. The users of the software will most likely be physicists or mathematicians."

The one to begin with...

[mirko]

...is TeX.

This typesetting program was originally aimed at the scientist. I don't know of any other software that produces nicer documents.

Re:The one to begin with...

[zuvembi]

TeX doth indeed rock. I started using it for (of all things) doing a family cookbook. Which I found it did many times better than a normal word processor.

Now I've started using it for reports and documents at work (anything to save me from MS word). I started using Lyx at first, but I found I actually liked doing LaTeX by hand better.

An old math favorite

[imrdkl]

Was Are you ready for Calc III. This, and alot more math software can be had from the UofA Math Software Page.

Open Channel Software

[Xpilot]

Well there's always this.

I recall /. running a story about NASA donating some stuff to this site...

Re:Open Channel Software

[Aaaaaargh!]

I wish NASA had actually released the software into the public domain gratis, not through a commercial vendor that's allowed to charge fees in excess of distribution costs. I'm sure it's all reasonably priced (and what I shelled out a few hundred bucks for was indeed reasonably priced). Being a citizen and long-time taxpayer, however, didn't a portion of my hard-earned money pay for this software to be developed?

Ooh, I feel a rant starting, so I'd better leave off before I drift offtopic :)

Reasons to not bother with Windows

[wrinkledshirt]

I know this isn't entirely the point of your question (and more than a little bit of this is motivated by my anger towards MS's recent settlement), but I just thought I'd put forward the idea that you shouldn't bother with Windows at all.

If you're hurting for cash for software, the outlook is probably not all that great for hardware too, right? The cutting edge of Linux and the various BSDs all run well on hardware that the latest Windows versions cough and sputter on.

Also, providing a Windows learning environment is only going to encourage use of Windows down the line, which will require further investments, software AND hardware upgrades etc.

If you're working with a blank slate, and these people need training anyway, might as well put it towards something that won't come back and make serious demands on your checkbook. Save the money for additional learning resources, a CD burner to replicate software for yourself (this is legal with the Linux and BSD OSes), etc. Don't go down the proprietary road, or else soon enough you'll be dealing with the same MS-driven crap the entire Western world is trying to handle right now.

Re:Reasons to not bother with Windows

[Reality Master 101]

Anyway, back to my Red Cross story, they wanted me to go through these two Excel spreadsheets of volunteers to weed out duplicates and it looked like a dauntingly tedious process,

Of course, you could have just merged the two lists in Excel, sorted them, and then written a VB program to delete the duplicates. What, 2 minutes work?

Just because you don't know how to use a tool doesn't mean it's a bad tool.

Re:Reasons to not bother with Windows

[SharpNose]

No, I couldn't have, "Reality Master." The duplicates could only really be detected by eye, as the two lists of volunteers were data collected by ear and typed, and as such had terrible discrepanies. The fields weren't at all chosen with an eye toward data quality or usability - "name" was a single field that might have been last name first or first name first depending on who typed in the record.

Do you really think I wouldn't have sorted the list if doing so would have helped?? Come ON!

Re:Reasons to not bother with Windows

[nmarshall]

or you could export those lists to csv and use some perl magic to merge them. im going to bet that using perl would be MUCH easyer then VB...

just because you have a tool doesn't mean that it's the best tool for the job.

Re:Reasons to not bother with Windows

[Remote]

they wanted me to go through these two Excel spreadsheets of volunteers to weed out duplicates and it looked like a dauntingly tedious process, so I converted the spreadsheets to comma-delimited text files and booted the Dell I was given to work with to a Linuxcare CD, mounted the disk, and used cat and grep to go through the list at several times the speed I was expected to go at. If I were a "Perl Monk" I am sure that I could have blown through it in even less time.

Or you could have done the same with tools written for Windows, only replacing type for cat and loosing the CD boot/mount thing.

Of course, I see your point. Unix is inherently more flexible when it comes to doing non-standard things, and utilities talk to each other much more seamlessly. What I want to note is that there is an enourmous world under Windows beyond what Microsoft offers, some of it open source. If a staff is already comfortable with an OS, I don't think it would be wise to migrate, except if there are at least two people proficient with Unix (which might well be the case) and time and budget for training. OTOH, maybe your example sprung up to my eyes just because I'm so used to using Borland's grep that I'm beginning to feel it's part of the OS!

A note on distributions: I imagine the situation in Africa as being similar to the one in Brazil as far as hardware is concerned, that means a lot of cheap/old cards that may not be supported by many distros. If you (the submiter of the original question) face that kind of problem, try Conectiva Linux. They have paid special attention to that aspect.

Re:Reasons to not bother with Windows

[DrSpin]

Just because you have a troll, it doesn't mean its the best troll for the job.

Try NA/European physicists & mathematicians

[hearingaid]

I worked for a little while in a government research library, and about half the people in the building were both scientists and programmers. They developed a lot of their own tools, and most of them were coding for some *nix, many on Linux.

They didn't care about other people getting their code. I would expect universities to be the same way.

As for bandwidth, that's much less of a problem now with CD burners. I'm assuming your Third World people have CD-ROMs, but given that, if you can talk to some First World scientists & get them to burn and ship, it might well be cheaper.

VI + EMACS

Quick question

[acidblood]

If you have no resources for purchasing scientific software, where did you get the money for purchasing MS Windows licenses?

Moderators: THIS IS NOT A TROLL. The question is simple: if you're already w4r3zing Windows, what refrains you from w4r3zing your scientific software also, and in the process saving us from these terrible Ask Slashdots of late?

Re:Quick question

[duffbeer703]

Microsoft products, Windows included, is licensed for signifigantly cheaper prices abroad.

Microsoft also donates alot of Windows licenses and other software to scientific and other institutions overseas.

Re:Quick question

[jeanray]

Also, windows licenses are a lot cheaper then most research software..

Re:Quick question

[SirSlud]

[offtopic]What's a non-terrible ask slashdot, or are you just upset that half of them don't involve games anymore? Given current events, I find it hard to believe that trying to get some of the more poor places in the world up 'n running in so far as marketable skills and data goes constitutes a poor Ask Slashdot.[/offtopic]

Re:Quick question

[windi]

->The question is simple: if you're already w4r3zing Windows, what refrains you from w4r3zing your scientific software also

Easy. It's a lot easier to find a copy of Windows than it is to find a copy of any specialised scientific program.

SAL: Scientific Applications on Linux

[gylle]

SAL is a good resource for finding science apps that run on Linux. Worldwide mirrors, many apps are free.

SAL - Scientific Applications on Linux

[Anonymous Coward]

This is most likely the most complete site out there when it comes to science on linux. http://sal.kachinatech.com/

linux box has some listed

[Saoi]

linux.box.sk

They may not all be the best but as a physics student some can be kinda cool to play around with.

Netlib and more

[apsmith]

The standard resource for free scientific software (unfortunately mostly written in Fortran) is Jack Dongarra's netlib: http://www.netlib.org/

It's best in linear algebra (matrix problems etc) but there's other good stuff in there - FFT routines, statistical stuff, some deep mathematics, and more... Also, not free, but good, is the standby Numerical Recipes book, which includes source code for a large variety of uses, particularly solution of nonlinear optimization problems.

Other stuff is available free from the supercomputer centers - at least they used to give stuff away free, though NCSA at least seems to have tried to make money off their things lately...

Re:Netlib and more

[Wile E. Heresiarch]

I do quite a bit of number crunching. Here are
some of the resources I use:

Netlib (www.netlib.org) -- Yes, it's mostly Fortran, but that's a good thing! Just use f2c (easy to find) and translate to C if that's what you want. Don't underestimate the power of decades-old programs -- old == widely used and well-tested.

StatLib (lib.stat.cmu.edu) -- Collection of statistical software, in various languages, including C, Fortran, and S.

SAL, Scientific Applications on Linux (sal.kachinatech.com) -- a very large collection of links.

Freshmeat (www.freshmeat.net) -- Not scientifically oriented, but there is much scientific stuff there, along with all kinds of miscellany.

Octave (www.octave.org) -- A package for matrix manipulations, similar to Matlab, but free. Useful for all kinds of problems.

R (www.r-project.org) -- An implementation of the S language for statistics, but also useful for general problems, similar to Octave. S+ is a commercial implementation of S.

Well, that ought to be enough to get started. To echo something other posters have mentioned -- don't even bother with Windows software. If your budget is tight, save your money for hardware, don't waste it on the MS tax.

Re:Netlib and more

[altstadt]

Why is it that whenever this topic comes up, everybody always talks about Octave and gnuplot as if these are the only things available?

If you want a self contained program that runs on multiple platforms, take a look at Euler. This is about as close as it gets to being a MatLab clone.

astro software & some stats too.

[fiiz]

It is actually not that easy to find free physics software.

For professional astronomy software, I recommend http://star-www.rl.ac.uk/

Some nice but steep stats software in the R project http://www.r-project.org/

And you can use Octave & gnuplot for basic maths. (admittedly not as good as mathematica,matlab or some other maths package.)

This URL http://www.seul.org/sci/seul-sci10.html has a review of linux & GPL packages that are useful to scientists.

It is also probably worth asking some of the software vendors if they would like to donate something, as really, you never know! (if the cause is good...)

Good luck!

Physics Analysis Workstation.

[matthayes]

Great for graphical representation, and statistics. Released under GPL.

I remember using it about three years ago under Red Hat for reconstruting cosmic ray showers. Can't see any possible problems with Debian...
It was great for what I was doing.

Matt.

Re:Physics Analysis Workstation.

[ErfC]

I've used PAW quite a bit for my work. It's quite effective at stuff, but the documentation is abyssmal. I found it really really painful to learn, and as a result I didn't get very far into it.

Something almost as hard to learn but somewhat easier to actually use is Physica, developed at TRIUMF. It's the main program I used to do my M.Sc. analysis work. :)

For data aquisition (and generally running an experiment), I strongly suggest looking into MIDAS. It's really powerful, and has a web interface (with optional password protection), electronic log book, etc, which is really helpful for experimenters to keep tabs on things from home. Especially when "home" is in another city (or even country).

University of Tokyo Physics

[r.suzuka]

I am a student of Physics at the University of Tokyo and my superiors have instituted a plan that accomplishes many of these aims.

We have correspondence programs with several universities in Africa in which we will provide to them our outmoded hardware. It is unfortunate that often, we are not able to replace our hardware as often as we would prefer, but when we do, we attempt to find a physics department without adequate hardware.

Also in the course of completing their theses, graduate students must write various software tools to assist them. The copyright to these tools belongs to the University if I am not mistaken. Although my University does not distribute these freely as some would prefer, they are sometimes provided to the other universities which have the hardware necessary to run them (with the consent of the programmer student of course).

Yes, there is more that may be done, but I believe that we are working to genuinely assist other physics programs which are less fortunate that we are in some respects. Does anyone else know of similar programs?

Theorem proving software

[reachinmark]

For the more logic inclined mathematicians, as well as anyone interested in structured proofs, theorem proving, etc, the HOL theorem prover is a very powerful engine. On the down side - it can be tricky to learn, but there is a large quantit of documentation and a big user base to help get people started.

So Internet is too slow to download distros?

[arminh1974]

Now here's something where the average joe without coding skills can help promote free software. How about offering to burn distros & RPMs/DEBs and mail them to africa or other places where the infrastructure isn't so great? The costs shouldn't be too horrible ... maybe we can set up a network of volunteers for something like that? I myself don't have a CD-burner at the moment (relocated from US->EU recently), but I can punch out a simple database-driven website quickly ... if anyone's interested, mail arminh(AT)usa.net ... maybe we can get something going?

Re:So Internet is too slow to download distros?

[ghoti]

Could somebody mod this up, please? I think the idea is great!

Re:So Internet is too slow to download distros?

[DrSpin]

The mail can take three months in most of Africa. Anyway, it would be a complete waste of time sending a CD, as it would be stolen by an illiterate hoping for Abba's greatest hits.

The web site idea is good, but you should also collect names of people travelling to Africa, who can carry a CD and drop it at a school or University. Loads of people travel who could drop off a CD.

Or maybe the people who need the CD could arrange for someone to pick up from a European or American address posted on the web site.

Electronics schematics capture package

[Grab]

If you're in need of a package to draw electronic circuits and do general schematic capture stuff, check out Pulsonix. These guys have made a fully-featured electronics schematic capture program freely available to anyone who wants to download it. The only downsides are (a) it's 19MB, and (b) it's Windows-only. Highly recommended.

The package also contains a PCB design package and other good stuff; however, you have to pay to unlock these (not excessive amounts by the standards of most design packages, but £1-2K is a lot for someone in a developing country or your typical hobbyist). If you're on a real budget, just use the schematic capture part to produce netlists, and then use an old DOS/Win3.11 PCB layout program such as BoardMaker for the PCB design.

Grab.

Re:Electronics schematics capture package

[ScottBob]

What I'm looking for is freely downloadable scientific software where you don't have to give them your personal info before being allowed to download it. It's pretty damn bad when you have to look for warez versions of free programs just because you don't want vendors harvesting your personal info to sell to others.

Re:Electronics schematics capture package

[Grab]

Agreed. But (a) you don't have to be honest :-), and (b) you are getting a seriously good bit of kit for the exchange. Since this is the only freely-available (as in "pay no money") schematic capture program I know of, there ain't much choice.

Grab.

Re. Matlab under linux (wine)

[Saoi]

After finding the differences between octave and matlab too much as pointed out I tried finding the unix/linux version.

If you want to use GAP for research or teaching and can't download it (we've had people whose bandwidth is too low, and people whose countries do not allow arbitrary internet downloads for political/religious reasons) let us know (mail one of the addresses on the Web site) and we can usually manage to send a CD.

Why not instead put all american scientists (with all their funding) in countries with less opportunities to give money to research? This would give a lot of job opportunities as well.

Your idea is probably the most stupid I've seen so far today.

Re:Physics Analysis Workstation - ROOT

Oh yes, runs on Linux and Windows...

Re:A better solution

[Huge Pi Removal]

I have to disagree with that...

It would be really nice if research could be done, freely, across the world. If everyone leapt into America every time they wanted to {start a business|do some research|etc, etc} then America would be:
1. Overcrowded, and
2. Resented by the rest of the world for "stealing" all its talent.

I don't see that Africa is "cut off" from the rest of the world. They have phone lines to send e-mail down, and geographically Africa's a lot nearer to the rest of us in Europe than America is. Or do you think "cut off" simply means "cut off from America"? And anyway, if no-one else biult up their research facilities, that means all research ends up in America anyway, which is a Bad Thing(tm) (see above paragraph).

Personally I'd love to see these people being helped to do what they want, in a country that they feel is home. I sure as hell'd think twice before going to some states in the US if I were black.

Hope that wasn't an anti-American rant. I know my posts usually are...

Re:Do we want advanced scientists working overseas

[ghostlibrary]

Ironically, with Bin Laden a) being suspected of having advanced weapons and b) being a millionaire, I don't think for-pay software is an impediment to him.

Frankly, when for-pay software is still cheaper than a few rifles, any third-world arms program isn't going to be hurting. Remember, warlords and tyrants skim the cash first-- and if they can afford to build the stuff, the software costs are negligible.

No, free scientific software really benefits education, schools that can't afford resources.

Re:A better solution

[puma_duh]

Oh yeah, why don't we just grab every smart person in the world and put them in the U.S., and just let the "rest" of the world starve to death. That would be a great idea too, uh?!?

There are other countries in the world, and there are people who *like* to live in other countries (yes, believe me, there are people prefer to live in other countries than in the U.S. - aren't them crazy?)...

Besides, science should not and cannot be developed in a single place in the world. Research is much more efficient if distributed around the world, accordingly to the resources found in each site...

TISEAN

[Skorpion]

A very good package for chaos-theory-oriented numerical data analysis is TISEAN.

It does excellent job on its part. There is also some documentation on the site, including one of the creators' Ph. D. thesis that explains some of the theory behind the software. On Linux it requires gcc and GNU Fortran complier to compile (compilation is pretty straightforward).

I also found GNU awk extremely useful at numerical data analysis. You also would want to include Python and NumPy - python extension for numerical computations.

Re:Do we want advanced scientists working overseas

[puetzc]

I'm sure that this was thrown out as flame bait, but I will rise to the provocation anyway. bin Laden and other terrorists feed off of frustrantion, hunger and hopelessness. The best way to eliminate support for terrorists is to attack the factors that drive hopeless people to support terrorists for lack a better choices. I am not saying that all terrorists are motivated by economic and social factors, but that enough of their support depends on this to make third world improvements a good way to improve live for everyone.

A recent survey (essay) in the Nov 10-16 Economist (www.economist.com) discusses the surprising spread of technology into third world contries, and of the benefits to the inhabitants in terms of better diet, better governments, and a longer lifespan.

If we can assist and encourage the scientists and leaders in the third world to improve life in all countries, I think that terrorism will slowly whither away.

Some useful free tools

[spike_gran]

I managed to get my Physics PhD using almost entirely free tools.
The thesis was written in LaTeX, using emacs, and made printer friendly with dvips.
The data plots were done in gnuplot.
The simulations were written in c with gcc or Fortran with g77. For the matrix analysis algorithms I used LAPACK. For minimization routines I used some of the Numerical Recipes routines, which aren't free software exactly, but Numerical Recipes is an easy book to buy used off Amazon.
I know that all of this stuff is really old-skool, but, it all works fine.

Things I use at work...

[doop]

I'm doing a PhD on simulations of soft condensed matter, and mainly use either free software, or stuff we wrote in-house. Off the top of my head:

• VTKis a very good package for scientific visualization.
• Maxima is a Free computer algebra system, a bit like Mathematica. It can solve equations, do calculus, plot things, produce TeX output of what you've done, and lots more. Incredibly useful for long tedious bits of algebra.
• gnuplot is a versatile graphing package (2D and 3D, but maxima or VTK are IMO better for 3d stuff). As well as graphing, it can try to fit arbitrary functions to your experimental data.
• LaTeX -- it's very hard indeed to typeset equations better than LaTeX can.

If you're interested in condensed matter physics (or a few other areas), then you should have a look at the Los Alamos E-print server, which contains preprints of a lot of scientific papers.

Re:Things I use at work...

[brad3378]

&gt LaTeX [latex-project.org] -- it's very hard indeed to typeset equations better than LaTeX can

I can't speak for latex, but I higly reccomend Star Office for typing equations. Once you learn their key combinations, you can type equations very fast. Mouse menus are also available (for the harder to remember stuff).

Why not simply get the people they are colaberating with in the richer countries to post the software!? Its not hard, and if you are posting results and reserch papers to each other all the time, it is not as nieve as it sounds! (These guys do colaberate with other physics depts, right?)

Joking aside, I've used far too much Fortran doing scientific stuff.

Don't be silly

[sharkticon]

Well, I think these countries are in need of scientists.

Nonsense, what these countries need is food, healthcare and an end to the endless brutality of tribal warlords, not some ivory tower academics sitting around pondering issues. Until they acheive stability, there is no need for these countries to bother with providing for scientists, especially ones that can't compete with Western researchers anyway due to a lack of resources.

Why not instead put all american scientists (with all their funding) in countries with less opportunities to give money to research? This would give a lot of job opportunities as well.

How foolish! Not only would we be squandering a national resource, but we'd be sending our scientists to a life of misery grubbing in the dirt for food to life, let alone engage in constructive research.

I think you need to check your facts first before posting.

Re:Don't be silly

[Anonymous Coward]

Excuse me, but not all african countries are war-torn or starving, though many of them are very poor by our standards. For someone who urges others to "check out their facts before posting", you don't seem to know much about Africa yourself...

Anyway, fostering scientific research is one of the ways to help these countries develop. Only sending them aid is a sure way to keep them in a state of dependence, not development!

Haven't you ever heard the saying: give a man a fish and you'll feed him for one day. Teach a man how to fish, and he'll be able to feed himself for life.

Re:Don't be silly

[mip]

Nonsense, what these countries need is food, healthcare and an end to the endless brutality of tribal warlords, not some ivory tower academics sitting around pondering issues

Issues like better agriculture, healthcare and a way to build a decent society?

...especially ones that can't compete with Western researchers anyway due to a lack of resources.

Why would they want compete? I am sure they would be far too busy trying to improve their nations "life of misery grubbing in the dirt for food to life" Your arrogance is astounding. For you to say that "our great nation is suffering thanks to the perception of science as being less important than greed", while at the same time suggesting another nations' scientists should come to the USA so as to help its "brain drain" is, quite frankly, ridiculous. Do you even read what you write? Does that not sound like the workings of a greedy mind to you?

Some great scientific achievements have been achieved with minimal resources (remember Einstein anyone?) and for you to belittle and partonise the workings of another nation because you have all the resources and power is shameful. Your nation should contribute towards making their little machine run smoothly, not making them a cog in your enormous one.

Finally, I suggest that the original poster gets linux machines. Anything propiertary software would be a poor choice in a low budget setup. Keep it simple and keep it cheap. It may supposedly not have the support (I would have to disagree, I cope fine as a linux newbie) but it does the job and costs of upkeep are small.

Right, homeward bound.

a very good site ...

[fymidos]

is Scientific Applications for Linux (SAL), the one i use is in greece http://sal.duth.gr, but there are mirrors around the world.
I think the official site is at http://sal.kachinatech.com/ .

many applications there , not all free though ..

octave and matlab (student version)

[adapt]

while you can get Octave for free with most Linux dists. and you can contact the Octave people for tips about installation. the US student version of Matlab is cheap and does not have matrix size limitations AND there is a Linux version in the package. also, if you check Matlab website [mathworks.com , mathtools.net] , they have a huge ftp site of free goodies, i.e. Matlab toolboxes, that probably can be used with Octave too.

since i installed my student version of Matlab at home, i have used less my Octave. Matlab also can be bought at academic prices, which are still too expensive for cash-strapped academia.

as for linux vs. windows, if you have to leave you computer on for 10 days for a simulation, then linux stability is a nice bonus...

Python

[ceoyoyo]

I'm a student at a magnetic resonance research centre and we're looking for a new development platform. We've been using IDL but they've announced they won't be supporting Mac OS X. The leading candidate right now is Python with Numerical Python, Scientific Python and VTK.

Ecology

[Anonymous Coward]

there is a free software package for teaching ecology available from
http://www.cbs.umn.edu/populus/

it teaches some of the basic differential equations, some cellular automata, an "interaction engine" wherein you can enter your own diff eq's and view their outputs (only 2 or 3 can be viewed simultaneously), and a bunch of other things...

it is currently being developed in Java, and is available for all operating systems (that have Java)

check it out! it's "fun for the whole family!" you will see models that you have done in your school years (simple population growth) and a lot you probably haven't.

windows trap

[adapt]

yes, MS sells campus licenses at EXTREME discounts (like $20 for Office and less for the OSs), but the hardware requirements are heavier.

most people in academia are not swimming in cash, so this means old hardware, and an array of diverse machines connected to a server. linux is the ideal software partner for a small research group, in my opinion.

the other factor, as somebody else pointed above, is that GNU or public tools are used by almost everybody. most papers are swapped in .ps format and written in TeX on (insert favourite editor here :). in windows you can do the same, but integrated tools like Scientific Workplace cost money, and they are not really needed after you learn some shell and vi tricks.

still, the crucial factor that made me wipe out windows for linux was stability. when you do not have a double Xeon crunching numbers, you appreciate the fact that linux will not crash during the 3 days it must be ON. ;-)

Terrorists exist because they come from uncivilized, barbaric nations.

I can think of British terrorists, Irish, German, French, Spanish, American, in fact I think you'll find ALL countries have produced one sort of terrorist or another.

Terrorists do not come from uncivilised barbaric nations. Rather they are uncivilised barbaric people. An important difference, and one which we should all remember if the civilised majority, from all countries, is to oversome the terrorists from whatever place.

LyX

[Garrett Lisi]

http://www.lyx.org
an excellent free GUI for LaTeX. Writing my dissertation would have been even more painfull without it.

Weka- statistics and machine learning

[dukethug]

I use an open-source data analysis package called Weka.

It was developed in Java, and it's quite easy to modify and extend as you see fit. Solid documentation available on the website. Excellent CLI, decent GUI, decent graphics. Really useful for doing basic statistical analysis and using some of the more interesting machine learning techniques.

Re:Do we want advanced scientists working overseas

[duffbeer703]

The Unabomber was a lunatic.

There is a signifigant difference between a lunatic and a terrorist.

Terrorists are fighting for a cause. They see their acts as strikes against their enemies. Examples of this include the IRA, Timothy McVeigh and Hamas.

The IRA was supported by financial contributions from Catholic Irish in the South and Irish in the United States.

Tim McVeigh did not really have a movement behind him when he bombed Oklahoma City. He thought he did, though.

Hamas (and Osama bin Laden) is a terrorist movement who receives direct support from states like Syria, Iraq, and Iran as well as financial and other support from rich Saudi princes and other oil billionaires.

The Unabomber was a solitary maniac. He was a smart guy with a few screws loose who became totally unhinged when the woman he wanted to marry rejected him. His political agenda didn't develop until much later in his bombing career, and was mostly incoherent. The agenda of Bin Laden or Hamas is very clear and very coherent -- they are organizations at war.

Perhaps some evil corporate sponsorship would do

[lukegalea1234]

I wonder if a company like wolfram would donate mathematica for an endevour like this. It's unrealistic to try and make money of third world developement.. and if the ultimate goal here is to move these countries out of the third world, getting them hooked on the product would be great for the future.

linux is the answer

[dummkopf]

being a physicist myself (theory/computational physics) i have noticed that the main trend is to get rid of the expensive sun workstations and geat cheap pcs with linux on them. while we can have endless fights of what distro is the best, it seems that (at least in america) redhat (7.2 is highly recommendable and available via cd) is the choice for most scientific groups.

not only is it a free os, it also provides ALL the core tools you need to do research! for example you have TeX (+ several excellent text editors), the whole gnu compiler suite (and debuggers), excellent plotting tools for data and image manipulation (gnuplot, gimp, xgrace, ...) and many more. Institutions like CERN, or space telescope provide full packages with tools to analyze all kinds of data.

there are a lot of other scientific applications you can get for free for linux if you are in an academic environment and which are awesome tools to use for researchers. i have seen many responses already with good pointers to different places (SAL, freshmeat, CERN, IBM Open DX).

finally, once can also make computational clusters with linux -- really inexpensive ones!

mupad

[platypus]

Take al ook at mupad

It's some sort of mathematica lookalike, superior in some cases and they have free versions.

It's been a while since I used it, but it was great.

Re:mupad

[dido]

Have tried this. My ripes include the fact that is that it is somewhat slow (compared to proprietary computer algebra systems like Maple or Mathematica anyhow), and (gasp) it uses XView. Yes, the old GUI toolkit Sun once created for Open Look and their OpenWindows desktop.

The worst part about it is that it's NOT open source/free software, which means that you're basically betting that the folks at the University of Paderborn who developed it aren't going to stop maintaining it or will suddenly stop making versions of it that are freely usable. Keep this in mind if you decide to use it.

Re:mupad

[bcrowell]

All I could find on their web site was this:

• Fully-functional trial versions are available free of charge. They expire 30 days after installation.

I haven't used Macsyma for 20 years, so I don't know how good it is compared to other software right now, but there's an open-source version called Maxima, as pointed out by a previous post.

GIS system

Re:Do we want advanced scientists working overseas

[duffbeer703]

I was referring to Mideast terrorists in particular. They are a particular breed of terrorist movement and cannot be compared directly to terrorist organizations in Spain or Ireland. Unfortunately, I cannot edit my previous comment and clarify it.

The difference is that Mideast nations are RUN by the uncivilized, barbaric dictators and petty kings.

Western democratic governments are accountable to the will of the people. While organizations like the CIA have supported rotten regimes in Central America and Asia, that support rarely lasts a long time, since administrations and political power shifts every few years.

Online Learning Tools

[oo7tushar]

There is an organization called MERLOT. It's more of an online system where professors from Canada and the US submit links to sites with learning tools and programs.
Anybody can submit links but each link is graded by professors from Universities and Colleges that pay a fee (a really big fee). This system ensures that only the good tools get online. It takes a minimum of 3 stars out of 5 to be linked. This encourages improvements (rejections get feedback) in tools to become easier to use and more educational.
It's FREE (no registration at all) to and layed out into easy to navigate catagories (Arts, Biology, Math, Physics, etc...)

IRAF for Astronomy/Image Processing

[andrew cooke]

http://iraf.noao.edu/iraf-homepage.html is the standard data processing package in American/British astronomy (and possibly Europe too these days). I just noticed it is packaged inside Debian...

Although aimed at astronomy, it would be useful general image processing (particularly good at automating procedures over many images).

Re:bsd ports

It is bad to pay for software on Windows, and even worse to use windows for running those apps, as we all know WindowsXP blows ass berrys for particle simulation software, or any sort of real-time app, or massif simulation software for predicting waether, or the movement of the stars, or fluid dynamics..... i fact.. I have trouble thingking off any of the top of my noodle....

Fortran compilers

[the gnat]

This isn't going to help them as far as the bandwidth problem goes, but Intel now offers their Fortran compiler free for unsupported noncommercial use. This includes F90, which opens up a lot more opportunities. It does need a (free, still) license, so it's a little tricky to obtain, but still very worthwhile. As far as I've seen it's the only free F90 compiler for Linux and the only free F77 compiler besides g77, and it's likely to be far faster than g77 as well.

Re:octave and matlab and Ptolemy

[adapt]

$5 for MathCAD is a much better deal than my $100 for Matlab :) but they are very different tools.

nevertheless, outside the US where universities have less muscle to get good deals, student licenses are still expensive for the less-priviledged students. therefore, people go the GNU/Linux way.

Ptolemy is a good tool if you want to model and simulate systems.

Ptolemy

[adapt]

Ptolemy is a good tool for modelling and simulation.

From their website:

"The Ptolemy project studies modeling, simulation, and design of concurrent, real-time, embedded systems. The focus is on assembly of concurrent components. The key underlying principle in the project is the use of well-defined models of computation that govern the interaction between components. A major problem area being addressed is the use of heterogeneous mixtures of models of computation."

R (aka GNU S)

[KjetilK]

For my thesis in astrophysics, I have almost exclusively used the R-system. I find it brilliant. It was developed for statistic, but IMHO, it can be used for any numerical computational task, though in some areas, it may need more development (for example, it lacks 2D FFT, but that should be easy to fix.

R comes with Woody (Next Debian release).

Connections and Connectivity

[Joe Decker]

A note to FlashBoltzmann (admittedly a bit of a digression)--I notice that you point out that a lot of these folks have slow connections. I suspect that's true in a direct sense, but isn't it true that continental bandwidth to/from Africa is still pretty limited as well? It seems to me that there's a chance that an archive of related software, located on the African contient, might help the downloading time issues and give you a place to put a bunch of related software to make it easier for folks to find....

I really like Yorick..

[Anonymous Coward]

For doing math. It understands matricies of
arbitrary dimension so you can multiply
a 6 x 4 x 8 matrix by a 4 x 8 x 2 matrix and

are c-like syntax (scilab/matlab are UGLY),
Graphing, and MPI interface. Downside is
that it doesn't have that big a user following.

Numerical Python

[Devil's Avocado]

One of the issues I've often run up against when doing scientific programming is the desire for a *real* programming language to support the number crunching. This often caused huge frustration for me when I used Matlab and IDL. One of the nicest solutions I've found for numerical programming is the Numerical Python package. (http://www.pfdubois.com/numpy/ ) You get the numerical expressiveness of Matlab or IDL with the power of Python as a programming language for the half of your program that *doesn't* deal with crunching numbers. (In my experience it's actually usually more than half, even in heavily numeric code!)

Here are a few more links:

I use CERNlib.

[BitterOak]

CERNlib is a package for high energy physics created by CERN, the people that brought us the web.

It is geared for high energy physics data analysis, but it has many useful tools for doing things such as histogramming data and plotting data, as well as many other numerical routines. MINUIT, the minimization package that comes with CERNlib is the best around.

The package is FORTRAN based, and works with g77/Linux as well as other systems.

They Need Hard Copies

[Josuah]

A lot of people are providing excellent links to free scientific software resources, but one of the key points mentioned was the lack of a high speed Internet connection. FlashBoltzman also specifically said they were looking at Debian because of the applications bundled with it.

Based on this, I think what would help the most would be hard copies of the scientific software people have mentioned. I would also recommend looking at SuSE's boxed distribution, because it contains 7 CDs or 1 DVD worth of software. Spending a few hundred U.S. dollars to get a box into every organization is probably much cheaper than the amount they would have to spend on their slow Internet connections to download several GB of data to each organization.

However, those scientific and research packages mentioned aren't going to be part of any distribution. FlashBoltzman can post the resources listed here to a web page, but maybe he should routinely grab software and then each month or quarter burn a few CDs or DVDs to send to Africa.

A few favourites we use

[Professor J Frink]

In the past few years I converted our lab over to Linux and here are some of the tools we use for analysis:

• GCC for C/C++/FORTRAN coding. It's free, it's not the fastest in the world but it's competent.
• Octave is a great, free replacement for Matlab. For general data manipulation it seems fine, where it really lacks relative to Matlab is in the GUI.
• Gnuplot is a great all-round, all-purpose, scriptable plotting tool that can also do fitting. For general everyday tasks gnuplot gets used a lot in our lab.
• SciGraphica is a great 2d/3d/vector/polar/ plotting and analysis package. It is a little like an Origin clone so is pretty easy to pick up, and can be extended with Python plugins. I am one of the developers ;0) (although far too busy atm to contribute, anyone want to help?). More suitable for publication-quality plots and still heavily in development. A new release is imminent. Plug ;0).
• teTeX is the main (La)TeX distribution for Linux and you'll most probably have it in Debian anyway but for writing reports, articles, books, theses, even letters you shouldn't need to use anything else. Really.
• OpenOffice if you have to deal with mad, crazy, annoying .doc using people.

There's plenty more where they came from. Most distrbutions come with a lot of these things anyway. These are mainly analysis or document tools, there's plenty of other things for both these areas and any other which plenty of other posters have shown. I've written a little guide for my local group. Some of it's out of date (and some of it's wrong but I have better things to fix) but it does have a list of common tools we use. And, of course, SAL is a pretty comprehensive database of unix tools. HTH.

Help scientists in Africa: encourage them to leave

[nukebuddy]

Scientists in Africa, for the betterment of the world, would best be encouraged to leave. Their talents would be better spent in a country that can use those talents -- a country like the USA.

The following are the average IQ's of the polulations of sub-Saharan African nations. The upper limit for mental retardation is IQ 85. Every sub-Saharan African nation's population has an average IQ below this threshold:

Zambia 77
Congo (Brazz)73
Uganda 73
Jamaica 72
Kenya 72
South Africa 72
Sudan 72
Tanzania 72
Ghana 71
Nigeria 67
Guinea 66
Zimbabwe 66
Congo (Zaire)65
Sierra Leone 64
Ethiopia 63
Equat. Guinea59

These are not developing nations. They are incapable of developing. These nations can contribute nothing to the information economy and those few talented individuals who live in them would be helping themselves and the world if they would leave for a nation with a modern infrastructure that can support the kind of work they are capable of.

Scientific Ploting Software

[Millyways]

I have recently been trying to find a replacement for origin which has become the standard ploting/data manipulation program in our research department. Unfotunatly it is very expensive and we don't have to budget to buy the number of licenses we require.

I tried many free linux ploting programs many of them holding themselves up as origin replacements, and none of them had anywhere near the features or intuitive interface of origin.

I think the closest one I found was Grace (previously xmgr) which is great for generating plots but doesn't help much with the correlation and sorting of large amounts of data the way origin does. Several students in our department have used grace to produce the figures for their thesis's, mainly because the postscript file output works well with latex.

Any suggestions as to a better program would be greatly appreciated.

OpenDX

[Lockjaw]

I have been using a scientific visualization package called OpenDX. It is a complicated, but very powerful tool, and well worth the effort to learn if you have piles of data to look at. The documentation is good, and the mailing list has been newbie friendly. I used PV-WAVE in grad school, and spent a long time afterwards looking for an open source alternative - this is it. The only real downside is that it is a Motif app.

It used to be IBM's Visualization Data Explorer; they made it an open source project a couple of years ago (wow - go IBM). Available on a variety of Unix/Linux platforms and Windows (if you run an X server). We have it on two Linux machines and two W2k machines (latter using Cygwin/XFree86-4.1.0); 3D hardware acceleration is supported on the Linux machines - and presumably on windows too if we shelled out the $$$ for a commercial X server.
