IU explicitly supports Fedora, SUSE, RHEL, and Ubuntu. A friend of mine running gentoo was having trouble, called them up, and they got him in touch with someone who helped him out the same day.

The OBJ format sample model on the Pix4D site doesn't play nice with nice with Alias. Having to tweak either the OBJ data or the viewer to get a firsthand view of the model tells me this service is not quite ready for prime time, and likely in need of significant funding to get to production quality.

"Timmy, here's why your nose is runny! See? A rhinovirus! Here, let's take a picture and forward it to your teacher."

One of the currently available super-resolution microscopes, the OMX, is running at 1.2 million dollars.

Anyway, for a virus, you'd really want to use EM, and I've heard of some "cheap" SEMs available for around $400.

Trigonometric functions especially are always treated as little boxes that magically calculate what you need.

Amen to that — and the sad bit is that the truth is both simpler and more beautiful than SOH CAH TOA ever was. The chapter in Euler's "pre-calculus" textbook Introductio in analysin infinitorum* that introduces the trigonometric functions is entitled "On Transcendental Quantities Which Arise from the Circle." Small wonder sines and cosines "often arise in applications." Mutatis mutandis for Bessel functions, say, or spherical harmonics. Speaking of Bessel, while he never got around to a university education, he was the first person to calculate the distance to a star with reasonable accuracy — and it sure wasn't "easy"!

Seriously, though, if I catch your meaning correctly, I wholeheartedly agree — for math majors, at least, mathematics should be very far removed from mindless calculation — a large part of mathematical research involves trying to understand calculations well enough to know when they're unnecessary — or if they're even possible. After all, many of the things we'd really like to calculate are, in some sense at least, "incalculable."

As an aside, if you like calculus: try solving the differential equation

x'' = cx

for a few "natural" values of the parameter c and initial values x(0) and x'(0), say

c = -1, x(0) = 1, x'(0) = 0

or perhaps

c = -1, x(0) = 0, x'(0) = 1.

Practically speaking, a course in "mental arithmetic" seems like it'd be far more useful — for future mathematicians as much as everyone else — than a semester spent memorizing antiderivatives of inverse hyperbolic functions and Stewert-esque "strategies" for trigonometric integrals**, with little or no time spent on why they work — which actually is both interesting and instructive. When it comes down to it, it's more a matter of accident than design — students whose primary focus is science or engineering really do "just need the damn formulas," assuming they're unwilling to wait until grad school for a first course in, say, electromagnetism, so they have time to learn enough linear algebra and differential topology to prove the general Stokes' theorem beforehand.

As for "abstract algebra," it's interesting to note that authors — van der Waerden, say, or Artin, or Mac Lane — who actually studied with Noether and Hilbert never seemed to use the phrase: for the first few decades, it was "modern" algebra, then simply "algebra." Perhaps this is because it's essentially the same subject we all studied in high school.

Moreover, both homology and category theory both arose from concerns largely inspired by mathematical physics. The former, rather transparently; as for the latter, think about Courant's proof of the original "natural transformation" for a bit. This is my vote for the most beautiful theorem in all of mathematics. This paper of Mac Lane's is also interesting and instructive.

C++ only becomes slower if you use certain features that have a performance impact.

And virtually every useful feature of C++ that is not in its common subset with C is one of those.

What is the performance overhead of namespaces, typesafe object creation, references, function and operator overloading, use of const ints for array sizes (more efficient than C), non-virtual methods, STL (the word "virtual" does not appear anywhere in the STL sources), support for wide characters, protected/private modifiers, etc.? While features like templates and metaprogramming have performance tradeoffs, skilled programmers can use them to make programs that are faster than the corresponding C programs.

Example: if you use exceptions, there is a performance penalty.

And if you use operator new, you use exceptions.

Firstly, this whole point is spurious because you can always use nothrow new, which was put in the standard precisely for people who want exception-free code.

Secondly, the (exception-throwing version of) new may well be faster at error handling than malloc. For the very many programs that only catch allocation errors at the top level, setting up the exception handler is just negligible part of startup costs and far faster than checking the return value from each malloc for zero.

Even if you are doing fine-grained error checking around each call to new, it's not clear whether setting up the exception handler is slower than checking for a null-returrn. It is certainly far less error-prone.

The main slow downs you will see in your average C++ program, over the corresponding C, is the use of the string class

That and <iostream>. Once, I tried programming in GNU C++ for a system with an ARM7 CPU and 288 KiB of RAM. Even after applying all the link-time space optimizations I could find, Hello World statically linked against GNU libstdc++'s <iostream> still took 180 KiB. (Dynamic linking wouldn't even have worked because libstdc++.so itself is bigger than RAM.)

Many C++ programmers use printf instead of iostream. You're perfectly free to use whichever you want, depending whether you are more concerned with code size/performance or type-safety/extensibility.

Note that C++0x has features specifically designed to support a typesafe printf, which will completely own the very type-unsafe C version.

Furthermore, C++ templates allow code re-use with exactly 0 performance loss

As I understand it, C++ compilers implement templates by making a copy of the object code for each type for which the template code is instantiated. Once you instantiate a template numerous times, your binary gets bigger, and it slows down because it has to keep loading data from storage instead of caching it in RAM. This hurts especially on handheld platforms such as the Nintendo DS, which has only 4 MiB of RAM.

I agree that Nintendo DS programmers should limit their use of templates. Not sure why the many programs which are not targeted at the Nintendo DS (Even the DSi has 4 times as much memory) shouldn't be able to generate the far-faster code made possible by template programming (See the "Was it Worth It?" section here).

Frankly, there is no valid reason for starting a new program in C in this day and age.

This is true but only

either. No free redistribution, derived works, or anything. Just because the source code is available doesn't make something open source.

And only OSI can define what open source is?

• S: (adj) open-source (of or relating to or being computer software for which the source code is freely available)
• "Open source is simply programming code that can be read, viewed, modified, and distributed, by anyone who desires. WordPress is distributed under an open source GNU General Public License (GPL)."
• Open Source: "Software whose source code is published and made available to the public, enabling anyone to copy, modify and redistribute the source code without paying royalties or fees. Open source code evolves through community cooperation. These communities are composed of individual programmers as well as very large companies. Some examples of open source initiatives are Linux, Eclipse, Apache, Tomcat web server, Mozilla, and various projects hosted on SourceForge and elsewhere."
• "What is open source, and what is the Open Source Initiative?"

While the term "open source" was coined by the Open Source Initiative source code was open, visible to see, study, and modify as early as the 1960s. The hackers of the Tech Model Railroad Club at MIT in the '60s was posting their source code on boards for anyone to improve and optimize.

But then again that was before "hackers" was used as a negative word.

The Indiana University Center for Bioethics has an interesting bibliography about inmates and organ donation in the United States (not harvesting) http://www.bioethics.iu.edu/body.cfm?id=79. Obviously inmates are - in some states at least - not even allowed to donate their organs and in some cases not even to close family. The ethical questions concering the death penalty aside: Harvesting without consent is IMHO not an ethical thing to do under any circumstances. Whatever guilt there was has been paid with the death penalty, after that, the will of the deceased should be respected. In doubt, consider silence as a "no". That inmates are prohibited to donate organs (donate as in: Not for profit and of their own free will) is equally nonsensical.

And, nobody really knew what this early information meant. Even in April, some universities estimated the worst-case in the united states will be approximately 1,000 by May 18th (link) while the try number of cases was AT least 5x that (link). The actual cases were probably much more, and by july it was estimated at around a million in the US. Sure, it was becoming clearer that the death rate was small by then, but this couldn't have been known earlier on.

The response to this information was nothing draconian: no viruses were mandated or anything like that. People were simply asked to wash their hands, avoid coming out if sick, etc. Schools were shut down, but again not that big of a deal. Obviously the majority of the big cities in Mexico, the epicenter, were shut down. The only possible conspiracy-theory type reasoning that may be true is that companies making tamiflu and other drugs made a lot of money off of this. Without additional evidence, that doesn't mean the "hysteria" was manufactured.

All in all, everybody go to exercise their preparedness responses, and improve on them if they were deficient. I think the response, while probably not perfect, was pretty impressive actually.

I don't see how that's possible if he doesn't have the private key which is held by the client only.

The private key is held by the compromised host. Try this: Run ssh-keygen, create a key, don't use a password. Copy the ~/.ssh/id_rsa.pub file to another computer and add the contents to ~/.ssh/authorized_keys. Now you can ssh from the first computer to the second computer and you will not be prompted for a password.

If the account on the first computer is compromised, the attacker could gain access to the second computer because of this lack of password. The OpenSSH people realized this a while back and started to hash the contents of the ~/.ssh/known_hosts file. This file used to contain the plaintext names of the hosts on each line. See this article for some history of the problem. Even though the contents of known_hosts are now hashed, it may be possible to discover other hosts via shell history or other means.

Developing software in a research environment is challenging. There are a number of constraints and conflicting interests that make it difficult for researchers unfamiliar with software to be truly successful. To make matters worse, the relationship between academics and professional software developers is almost non-existent, in large part simply because the research community has limited funds available for software development.

I've worked with a number of research labs to help bridge this gap and have developed a basic set of guidelines for developing software in research environments. In the end, the most important thing to do is draw a clear line between research tasks and development tasks. Understand what is in your area of expertise (research) and what is best handled by software engineers and other professionals. Then, depending on your resources, either hire a full time development team, a part-time consultant, or work with your university's IT staff to find local resources (many universities provide software development services). The place not to look is in the CS department: those students are there to do research, not write software.

I've put together a presentation that outlines a number of the challenges and how to address them. This presentation has evolved over the last 5 years based on a few ongoing academic research projects that have applied the ideas in it. Most of the ideas are standard practice in industry, but applying them to academic projects can be trick.

First off, I really appreciate the well-thought out comments to my original post. I was expecting some flame-worthy comments and am pleasantly surprised.

Now, to make this a proper /. thread and go completely off-topic...

I want to follow-up briefly on the NIOS idea, as it's one I've bandied about in academic circles for addressing the challenges facing researchers who need software for data management or simulation. The standard approach is to find a research angle and have a grad student develop the application in exchange for a degree. However, most disciplines are reaching the point where the requirements carry no legitimate research value or are simply beyond the skills of students. "A [OO|XML|Java|Perl|Forth] Framework for Baconian Dymanics" can only be published so many times before the reviewers catch on. And, it's not really fair for a student who should be developing research skills to spend their time writing boiler-plate code.

Some labs are able to secure NSF or NIH funding for software development. But, once they have the money, it's rarely spent on professional developers. Instead, it goes to the lowest bidder (or a colleague's kid who learned HTML in high school) and the quality of the software takes a big hit. And, most scientific PI's have difficulty effectively managing software projects.

It seems that the NIH/NSF could invest in a National Software Institute that provides developers for academic projects. The trick would be not to become a typical consulting shop and instead develop long term relationships with the labs while building out shared frameworks/toolchains/(pick your favorite abstraction technique) that can be used across similar projects. It would also be important to hire developers who were interested in science and would take the time to understand the domain they're supporting. And, it would be essential to develop reliable QA and validation practices to ensure that the science they're supporting is reproducible (something that most people I've worked with agree is lacking in most scientific software).

Anyway, some of the foundational ideas are worked out in a talk I put together and have given to a number of different labs. It's more focused on how to get individual labs implementing good software development practices, but I've always wanted to see the core ideas scale to a larger service organization. If anyone's curious, the slides are at:

I love this post in the thread: http://www.ussg.iu.edu/hypermail/linux/kernel/0104.3/0107.html that says "And UNIX on a phone is pure overkill." We sure have come a long way in this regard since 2001 :-)

I'm so bored that I actually read the post in the mailing list and all the replies in the thread.

Just to be at the same time informative and to the point, the 7 replies so far have been as positive as this patch is in the linux kernel mailing list a few years ago.

File system objects are themselves imaginary. Although it is useful to create and store a hierarchical system for referencing the data on the disk, these things are programmatic methods to reproduce consistent references of data locations and metadata for the convenience of absent minded humans. They do not in fact have any physical existence at all. There is not a magical manila folder factory inside your hard drive. Any patent that relies on the presence or absence of these imaginary objects is iffy at best.

And further, "In Unix everything is a file."

http://www.opensciencegrid.org/

That way you can backfill the resource with jobs from VOs (Virtual Organizations, think projects/groups) you choose. It is similar to BOINC in the sense you can pick what science to support.

The idea is that the sharing will go both ways. You will give spare cycles to other users on OSG, and in return, you will be able to use spare cycles on other resources.

Spend some time on the OSG website reading the things under "Learn About Us". Also check out the research highlights to see what kind of science is being done on OSG resources:

http://www.opensciencegrid.org/About/Research_Using_OSG/Research_Highlights/Research_Highlights_Archive

(Shameless plug - I'm part of this team) The good news is that OSG have an ongoing effort to help you join your resource to OSG, and help your users get going on the grid:

When you get to training candidates for research, the curriculum is so tight that although the need for programming skills is acknowledged by reasonable department heads, the priorities are for other things, not programming. This is true of all experimental sciences where data are increasingly overwhelming. Greg Wilson did this workshop at the AAAS meeting a couple of years ago:
http://www.osl.iu.edu/~lums/swc/
When he had outlined both the need and the solution, he asked for a show of hands for agreement. Almost every hand went up. Then he asked how many would adopt and the number went WAY down.

Same thing pretty much. CIFS is an updated version of SMB, samba supports them both. This might clear it up for you.

Spinach has almost no iron content. Popeye was wrong.

http://soundmedicine.iu.edu/segment.php4?seg=238

Popeye's creators chose spinach -- instead of, say, brussels sprouts or broccoli -- because of an 1870 German study that claimed spinach contained about as much iron as there is in red meat!

In reality, this was nothing more than an accounting error. The scientists put the decimal point in the wrong place!

The iron content of spinach is actually one-tenth of what was reported. The mistake was corrected in 1937. It was too late for Popeye, though. Hed already been getting strong on spinach for almost 10 years!

Spinach does contain iron, but no more than other leafy vegetables.

In fact, the iron in spinach is not easily absorbed by the body unless its combined with an acid, such as a squirt of lemon juice.

http://blogs.ittoolbox.com/bi/websphere/archives/spinach-10166

Spinach took another hit in the early 90s when research into nutrition refined what we know about iron absorbtion. To quote the Innvista website: Although much lauded as a nutritional vegetable, spinach has a drawback in that, while containing high levels of iron and calcium, the rate of absorption is almost nil. The oxalic acid binds calcium into an insoluble salt (calcium oxalate), which cannot be absorbed by the body. The same applies to the iron, as it is bound, leaving only 2-5% of the seemingly plentiful supply actually available for absorption.

The spinach iron myth suffered two big falls. Cut to 1/10th and then further cut to 2-5% of that 1/10th. A pretty big data drop. I did a blog search of the spinach / iron combination and found a lot of entries from people taking spinach for the iron content who had never heard the correction to the myth. It is better to try and get iron from a range of foods rather then spinach along. Spinach has a lot of positive things going for it but iron is not one them.

Liberals can certainly defend their positions with legitimate arguments, but generally don't.

And you went to a "major university"? Do they give refunds?

I'm not basing this on the internet per se, although that is highly relevant in this day and age. My opinions are based on the 2004 Republican National Convention protests. The nuts handing out political fliers all over the city.

Well, it's a good thing that conservatives never do crazy stuff like that.

Propaganda produced by the likes of Michael Moore.

I applaud your even-handed assault on divisive political propaganda.

My own education in a major university.

I'm going to guess that you majored in something technical and didn't spend much time in classes that discuss public policy. Getting the flavor of academic political analysis based on fliers and student club activities doesn't count.

The endless parade of media personalities.

Again, a landscape entirely dominated by liberals.

Lets not forget the hordes of hipsters with their "I hate Republicans" signs, clothing, and tattoos.

I can't imagine conservatives being so crass.

We even have anti-conservative graffiti here in NYC.

Ah, yes, vandalism. A tactic completely isolated to the left.

Last but not lease - I've personally had to deal with liberals accuse me of a wide variety of bad things. I've been told I hate the poor despite the fact I'm not particularly wealthy. I've been told I hate minorities, despite the fact I'm hispanic.

For what it's worth, I believe that I've been accused of being anti-American, even though I am an American. I've also been accused of wanting "the terrorists" to win, even though I go to work every day and specifically work on projects designed to help catch them, which is more than most of the population is doing.

I've been told I hate gays, despite the fact I'm friends with a few prominent gay men.

You mean that people were--gasp!--making a rude and unfair assumption about you based on the actions of extremist elements whose political positions you happen to sometimes share? Say it ain't so! What kind of jackass would do that? Then again, does it bother you that the party you support has done such a good job of cynically exploiting anti-gay sentiment with their "protect marriage" propaganda?

I've never in my life heard a conservative in real life say anything like that to a liberal.

Well, you're presumably out of college, so I'm guessing you're old enough to have spent some time in bars. I just don't know what to say to that except to applaud your choice in bars.

I've never met a conservative teacher...

What "major" university did you say this was, again?

...nor seen conservatives take to the streets as a show of force...

No, I suppose that when conservatives do it, it's called protesting and not "taking to the streets as a show of force."

My point is just this - these kinds of t

There may be a valid argument for saying that ndiswrapper can't be GPL'd, but this isn't it.

You're absolutely right. Nobody is arguing about the license under which ndiswrapper is distributed.

In the article Linus is arguing about whether or not ndiswrapper, which is designed for the sole purpose of linking proprietary binary-only modules with the kernel should be treated as though it were itself a proprietary, binary-only module. The exact technical details start to get ignored as the conversation continues, but the concept is still the same.

You may want to read this discussion of module licensing from l-k to get some idea of just what really is being discussed.

The claim isn't that a cow isn't a mammal because it eats grass, it's that you can't keep calling a hamburger bun "a vegetarian meal" once you put a beef patty and two strips of bacon onto it.

NetApp did something innovative with WAFL; Sun then came along, reimplemented everything, and called it ZFS

Well. Innovative? Around 2000, Daniel Phillips developed a linux filesystem called Tux2 that was based on the same ideas as WAFL, ZFS and maybe BTRFS. He knew about NetApps patents but believed there was enough prior art.

Unfortunately for filesystem innovation, it looks like he got
bullied
by netapp, so the project was abandoned.

It would be great if the WAFL patents could get invalidated, or at least their scope tightened, so that creative people can get on with innovative filesystem development once again.

There's never going to be a stable API nor ABI. Straight from Linus. http://www.ussg.iu.edu/hypermail/linux/kernel/0512.3/0980.html

I did purposely ignore the PPUs. Unfortunately the PPU doesn't help that much for performance. The OS and network stack keep it pretty busy. Also, touching memory from the PPU that an SPU may use later significantly decreases performance (touching memory on the PPU brings it into cache, triggering a very expensive dirty update operation if the SPU reads the same memory later). The general rule for Cell programming is to pretend the PPU doesn't exist and code everything for the SPUs.

As for the GPU, no one has figured out how to use it yet (on the PS3) and even so, GP-GPU programs aren't nearly as useful as we've been led to believe. They work great for streaming graphics operations, but as another poster pointed out (in a strangely hostile response to my original post), special processors significantly limit the types of applications the chip is good for. While the Cell is proving to be useful for a number of applications (though not all - any pointer chasing algorithm (e.g. graph theoretic) is not going to perform well on the Cell), it's not perfect for everything. Adding the GPU to the mix further narrows the scope.

If you're curious about the overall usefulness of GP-GPU algorithms, go back through the literature and pay close attention to how they constrained each application to work on the GPU. In most cases, it won't scale out to real world uses. Incidentally, the same is true for most Cell applications at this point (even the ones I've written :) ).

Mod parent up. This is just IU using Chacha to power its own internal search portal, and forcing its employees to be unpaid volunteers for Chacha. Nobody's stopping students from using GOOG or anything else for their general web searches. RTFPR for more info.

I still think it's boneheaded and a conflict of interest, but let's not exaggerate it into something it's not. Oh wait, this is Slashdot, never mind.
