Comment 1977 Popular Electronics Article (Score 1) 66

This brings me back to the April, 1977 issue of (I think) Popular Electronics that had a recipe for creating solar cells at home using "3'7 Dimethylpentadecon-2-ol propionate". At the time, I was 13 and spent quite a bit of time bothering my science teaching trying figure out what 3'7 Dimethylpentadecon-2-ol propionate was and how to get some. Years later, I happened to look at the May issue and it turns out it was an April Fools' joke. Even at that time, I did laugh out loud. Anyway, if you want to see a description, check out Don Lancaster's "The worst of Marcia Swampfelder"

In addition, Marcia does have some suggestions about car stereo speaker orientation that are useful for winter driving :-^

Comment What helps acceptance of Academic Software? (Score 1) 314

A somewhat different question is: What helps acceptance of Academic Software. Off the top of my head:
  • An open source license
  • High quality, readable code
  • An active community
  • Test cases and nightly builds
  • Regular releases
  • A faculty member who is a programmer, or at least was a programmer.

There are many other factors, does anyone have favorites? Note that not all academic software is destined to be used outside of academia or to even survive past the end of the semester. That's ok.

Comment Software as a form of publication. (Score 4, Interesting) 101

I have 30874 on the Ptolemy II repository, see http://www.ohloh.net/accounts/cxbrx. Hauke Fuhrmann put up Codeswarm videos of the software evolution of the Ptolemy II project. See Chaotic, Less Chaotic. The number of commits is a poor measure though. I tend to make lots of small commits while cleaning code. A student doing a Ph.D., may make many fewer commits, but their commits have greater impact in the form of support for their Ph.D. We see software as a form of publication, see Software Practice in the Ptolemy Project.

Sandia says "along a journey by train across Kazakhstan to Kurchatov; while it was at another interim storage pad there; and along a truck route to a long-term concrete storage pad in northeast Kazakhstan." Wiki says "In its heyday Kurchatov (which was known by its postal code Semipalatinsk-16) was a closed city, one of the most secretive and restricted places in the Soviet Union."

Comment I made this while you were playing FarmVille (Score 3, Interesting) 220

I saw this great art car once, it had an immense amount of detail and was huge. There was not much clear space on it except in an area about 6"x8" that had a sign in the middle that said, "I made this while you were watching TV." I've been thinking of updating the saying to "I made this while you were $^&*ing with FarmVille". FWIW, I built a Snail art car instead of watching TV of frobbing with Farmville. Now, if I could only get away from Slashdot . . .

Comment Re:Textbook Publishers (Score 2, Insightful) 208

From TFA:

"Indeed, to the uninitiated, scholarly publishing is a curious enterprise. Simplified, it works something like this: universities or the government subsidize a professor's research. The professor, who is required to publish frequently for professional advancement, gives his research to a scholarly publisher, usually for little or no money. That publisher, who adds value through editing, peer review, and production, assumes the copyright, packages, and sells the research back to the university at a markup. And those mark-ups have proven significant over time, especially as the digital age has fostered an explosion of new databases and resources."

In my department (Electrical Engineering), new faculty are offered a support package to get started and then the faculty go out and get funding. At least 51% of the funding they find is paid to the University as overhead. It is difficult for faculty who don't have external funding to attract grad students or pay for computers. The funding comes from the Government, but much of it comes from corporations.

In my experience, publishers no longer do any editing. I had an expensive text book on "Quality" and the author misquoted John Kennedy. How could this get by an editor? Authors submit camera ready text to academic publishers.

In my experience, peer review is managed by an unpaid faculty member who distributes material to other unpaid faculty members who distribute the material to unpaid students who do the review and pass the review back up the chain. This is actually very good because it gets students to review the work of others.

The reality is that academic publishing is a dead-end. Journals are in trouble. Conference proceedings and self-publishing of text books are on the rise. Recently, he only thing that I've heard faculty say that publishers provide is that publishers sometimes show up at conferences with a table of books which faculty browse. This seems like a weak basis for a business.

Reading the TFA, it seems like the publishers should just settle. Georgia changed their ways.

I'm the original submitter, so mea culpa. What I did was search for "password" and did not find the earlier article. After I submitted, I searched for "Herley" and found the original article. I then tried to kill my own posting, including commenting that it was a Dupe. It was not apparent how to kill my own article, but I did not look harder. So, my feedback is: it would be nice if there was a really easy way for users to mark their submission as a dupe. Sorry about the dupe, I don't like them either.

Submission + - Please Do Not Change Your Password 2

__aapopf3474 writes: Mark Pothier's Boston Globe article, Please do not change your password," covers a paper by Microsoft Researcher Cormac Herley, "So Long, and No Thanks for the Externalities: the Rational Rejection of Security Advice by Users," from the 2009 New Security Paradigms Workshop. Herley argues "that user's rejection of the security advice they receive is entirely rational from an economic perspective." Herley discusses "password rules," "teaching users to recognized phishing sites by reading URLs" and "certificate errors". Users obviously choose bad passwords, but does password aging actually help? There was some discussion on TechRepublic, but I'm sure slashdotters can bring some perspective to this. I'm especially interested in hearing about studies about password aging.

Most of the steampunk hardware is DIY. It is not like one can go down to Home Depot and buy a steam engine. Vintage steam hardware requires rehabilitation, including fabrication of impossible to obtain parts. I participated in making a Snail Art Car, which we wrote up for the DYI website Instructables. Another car, the Wrecker, is an electric carriage with hand-built wheels. Yah, he did not mine the lead for batteries and the differential came out of some old car, but the vast majority of this car is DIY.

Total disclosure: I've worked on Soft Walls.

There was discussion on Slashdot about the Soft Walls Project that did something similar. See the 1/04 and 7/03 discussions.

What I find interesting is just how vehement software engineers and pilots are about the idea, and yet everyone seems to trust fly-by-wire.

There is Soft Walls FAQ that covers common objections.
