South Pole Telescope Data Places Better Limit on Neutrino Mass 25

An anonymous reader writes an excerpt from a press release by the University of Chicago: "Analysis of data from the 10-meter South Pole Telescope is providing new support for the most widely accepted explanation of dark energy — the source of the mysterious force that is responsible for the accelerating expansion of the universe." The research resulted in three papers involving new constraints on the mass of neutrinos, a measurement of the angular power spectrum of the CMB, and a catalog of newly discovered galaxy clusters. The data lends a bit more support to the cosmological constant theory of dark energy.

Comment Been There, Done That (Score 1) 424

Word for word, I thought your submission was something I wrote. I've been there, done that, so it is possible. The mess I inherited took me 6 MONTHS to fully comprehend and formulate all plans of attack. Meanwhile, I was trying to fix and maintain what I could.

To tackle the whole problem, where did I start? Everywhere, frankly. There was no one starting point. Everything was affecting everything else. I did my best to get written down exactly what was running on each server, including running daemons, system crontab, and all user crontabs. Basically, build a list of what exactly you can determine. Then, try to get into the mindset of your predecessor and try to understand why (as best you can) to see if that sheds some light on what else may be lurking out there.

I didn't get bogged down in formal documentation because I knew I would have to rebuild everything. I took copious notes and drew pictures of what I thought were the processes of the system, but this documentation was just for my own benefit. Once I could identify unneeded processes, I shut them down or side-stepped them and hoped I didn't break anything; if I did, that was just more information at my disposal. Other processes I simplified and consolidated where I could. Eventually, the system got more and more comprehensible.

Once I "got" everything that was going on, I built a fresh new setup that focused on simplicity and efficiency. This is when I focused on documentation. I kept the legacy system dormant but available, just in case.

Now, we have a darn good system in place. I used virtualization to segregate different services and to enhance security. Maintenance is now preventative. Management is happy because they can now grow the business without everything imploding. The focus of my work today is building new products and services. I hope my successor doesn't complain.

Piracy

Inducement To Piracy, Adobe Style 272

S Vulpy writes "A post at the Social Science Research Council's website talks about how piracy greases the wheels of the Adobe Creative Suite marketplace by making it easier to deal with Adobe breaking compatibility between versions. Quoting: '... such incompatibility doesn’t involve exotic functionality, just straight text layout into columns and boxes. The kind of stuff that has been core functionality of publishing software since the early 1990s. Translate this dilemma to Brazil or Russia, where incomes are a fraction that of the US and you get a very simple outcome: massive piracy of Adobe products. In fact, go through this process in the last month of a 4-year project on a deadline and one could understand becoming extremely sympathetic to such a perspective. This, as we’ve argued, is not a defect of the Adobe business model, it is the business model.'"

Comment Privacy vs. Open Records (Score 1) 485

There is an assumption of privacy at universities; however, the university I worked for was subject to the public's open records requests. When requested, our IT department had to hand over the email of any employee (maybe student?). I believe this is a federal law (in the US).

Expanding on that concern, I wonder if online services allow IT departments to perform what is necessary for open records requests, or would that be a violation of TOS?
