jdupuis | November 5, 2010York University Computer Science & Engineering professor Anestis Toptsis was kind enough recently to invite me to speak to his CSE 3000 Professional Practice in Computing class.
He gave me two lecture sessions this term, one to talk about library-ish stuff. In other words, what third year students need to know about finding conference and journal articles (and other stuff too) for their assignments and projects. You can find my notes here, in the lecture 1 section.
In the second session, which I gave yesterday, he basically let me talk about anything that interested me. So, of course,…

Should Students buy an iPad or a Year's Supply of Pot Noodles? | blog@CACM | Communications of the ACM
"Suppose you gave up washing clothes for a year, or relied on your mum to do it for you. According to the budgeting guide this would save £222, just about half of the iPad. You could go with dirty clothes for your first two years and buy an iPad for third year, I guess. How about food? The budget reckons £1295 for a year. Sheer extravagance! Two Pot Noodles a day would cost under half that at £547.50. Throw in some vitamin supplements at £1.69 and what more could you need? That saving…

slacktivist: Hold on to the good
"Test everything. Hold on to the good.
That's from the Apostle Paul, actually. It's a bona fide biblical commandment. Both parts of it. Test everything. Hold on to the good.
Note the difference between the first part and the second. "Test everything" is unconditional. What should we test? Everything. But the second part is conditional. We're not told to hold on to everything…
oracknows | October 13, 2010October is Breast Cancer Awareness Month, a fact that is hard to escape. It's one of those things that I have mixed feelings about, particularly now that I've had a close relative, namely my mother-in-law, die of breast cancer less than two years ago. On the one hand, the attention that's brought to the cause of breast cancer is helpful for spurring research and donations to support research, as well as promoting screening programs. On the other hand, I do now have a bit of understanding about "pink washing," and some of the whole "pink thing" at times makes me uneasy. Be that as it may, one…

gregladen | September 29, 2010This is an excellent guest post by Scott Rowed on the use of Linux in K-12 schools, including strong evidence that school districts that do not have students using the Linux operating system are placing their students at a disadvantage, as well as a description of one outstanding success story in British Columbia.
Linux in Schools
Scott Rowed
What computer operating system should students learn at school? Most schools use MS Windows or Mac, but a number have switched or are in the process of switching to Linux. For schools the advantages are lower costs, greater security, no viruses or…

ably | August 31, 2010Our friend Victoria Stodden is the lead author on a paper published today in Computing in Science and Engineering summarizing the recommendations of a roundtable we participated in at Yale on data (and code) sharing in (computational) science. Seed's Joy Moore is an additional author on the paper.
To adhere to the scientific method in the face of the transformations arising from changes in technology and the Internet, we must be able to reproduce computational results. Reproducibility will let each generation of scientists build on the previous generations' achievements.... Reproducible…

So, Nature Reviews Genetics has an article, "Computational solutions to large-scale data management and analysis", which claims the following in the abstract (italics mine):
Today we can generate hundreds of gigabases of DNA and RNA sequencing data in a week for less than US$5,000. The astonishing rate of data generation by these low-cost, high-throughput technologies in genomics is being matched by that of other technologies, such as real-time imaging and mass spectrometry-based flow cytometry. Success in the life sciences will depend on our ability to properly interpret the large-scale,…
drorzel | August 30, 2010Last week, John Baez posted a report on a seminar by Dzimitry Matsukevich on ion trap quantum information issues. In the middle of this, he writes:
Once our molecular ions are cold, how can we get them into specific desired states? Use a mode locked pulsed laser to drive stimulated Raman transitions.
Huh? As far as I can tell, this means "blast our molecular ion with an extremely brief pulse of light: it can then absorb a photon and emit a photon of a different energy, while itself jumping to a state of higher or lower energy."
I saw this, and said "Hey, that's a good topic for a blog post…

Williams College - The Purple Cow goes national: ESPN College Football GameDay commercial looms
"In 2007, when I was but a wee sophomore at Williams College, ESPN College GameDay visited our campus marking the first and possibly last time they visit a Division III school. I thought that would also be the last Williams College would ever hear from ESPN. Boy, was I wrong, and glad to be.
It was an ordinary Wednesday (May 4th) when I received a call from Eph Sports Information Director Dick Quinn (DQ) asking if I knew how to get my hands on the Purple Cow mascot outfit, because if I did, then…
drorzel | August 23, 2010I'm a big fan of review articles. For those not in academic science, "review article" means a long (tens of pages) paper collecting together the important results of some field of science, and presenting an overview of the whole thing. These vary somewhat in just how specific they are-- some deal with both experiment and theory, others just theoretical approaches-- and some are more readable than others, but typically, they're written in a way that somebody from outside the field can understand.
These are a great boon to lazy authors, or authors facing tight page limits ("Ref. [1] and…
