California In the Running For Tesla Gigafactory

vossman77 Re:Texas? (171 comments)

Not that I want to defend Texas, but based on the wiki-table, you posted:

Texas produces the most renewable electricity (w/o Hydro) at 37,784 GW.h of any state in the USA (California close 2nd). I just happens to be a small percentage of its total electricity usage.

How Did Those STAP Stem Cell Papers Get Accepted In the First Place?

vossman77 Re:I can't imagine... (109 comments)

Yes, they can actually look at the plagiarized sections and fix them. The reaction tends to depend on how I contact them. If I am nice and say they can redo it for most the points, they admit their mistake and fix it. If you say they are getting a zero, then they start lying and say they do it in other classes and it is fine.

How Did Those STAP Stem Cell Papers Get Accepted In the First Place?

vossman77 Re:I can't imagine... (109 comments)

Self-delusion seems to be extreme or unlikely in this case. Based on this blog, she plagiarized her entire abstract only changing the cell name from ES to STAP.

A simple plagiarism detector would have detected this fraud. I run turnitin.com service on all my students' papers and I catch plagiarizer every semester. I think this should be routine for high profile article going in to Nature or Science.

Scientists Publish Letter Saying, "We Need More Scientific Mavericks"

Well maybe we should start funding more basic research or off the main path ideas.

Open Source Brings High-End Canon Camera Dynamic Range Closer To Nikon's

vossman77 not chromatic aberration (88 comments)

While I thought the results were cool, I was annoyed by the bloggers use of the word 'chromatic aberration' instead of color noise.

Chromatic aberration means the lenses bend different colors of light differently resulting in color fringes around the edges of object. Color noise which is observed in low-light conditions here is not an aberration effect of the lens, but pixel counting noise on the CMOS detector.

Ask Slashdot: Should More Math and Equations Be Used In the Popular Press?

vossman77 Re:Arthur C Clarke (385 comments)

In "Brief History of Time" Stephen Hawking states that "Someone told me that each equation I included in the book would halve the sales. I therefore resolved not to have any equations at all. In the end, however, I did put in one equation, Einstein's famous equation, E = mc^2. I hope that this will not scare off half of my potential readers."

Red Hat Launching Its Own Community Distro of OpenStack

vossman77 Glad to see the community benefiting (25 comments)

Glad to see the community benefiting from a fork. Usually when canonical makes a new project the community loses because we get two of the same thing and neither work well (see GNOME3/Unity or Wayland/Mir). I fully support RedHat's approach to improve existing technologies rather than scraping existing project and creating crap.

The Most Unique Viruses of 2012

vossman77 real viruses (94 comments)

I was disappointed to find out this was about computer viruses. Nothing in the description makes relevant to computers until the word malware.

The most unique biological viruses would be much cooler to look at than some stupid man-made computer virus.

Microsoft Urges Businesses To Get Off XP

vossman77 $500,00 equipment with WinXP (727 comments)

We have a few expensive microscopes with WinXP on the corresponding machine, an expired service contract and in reality cannot upgrade without buying a new microscope (an newer drivers), so what do you do, other than put it behind a firewall and hope for the best.

Single-Ion Clock 100 Times More Accurate Than Atomic Clock

vossman77 atomic clock accuracy (169 comments)

Yes, because being off by 2 seconds every billion years is something to worry about. I am sick of having to adjust my watch for the inaccuracy of atomic clocks.

Sheffield Scientists Have Revolutionized the Electron Microscope

vossman77 Re:original article (90 comments)

After reading the paper, they are definitely doing something novel, but the claims made in the paper far exceed what is being presented. Imaging bacteria cells is considered pretty easy -- show me some atoms.

A Rant Against Splash Screens

vossman77 Memory bloat (477 comments)

I think I would prefer office to boot with a splash screen rather than suck up memory when I am not using it.

I especially hate it, when I choose restart and the OS has open all these stupid programs. When I rarely hit restart, I was a fresh system.

Ask Slashdot: Which Ph.D For Work In Applied Statistics / C.S.?

vossman77 Are you sure you have a choice? (173 comments)

In my experience when the lab moves the students either (1) get a degree from old university or (2) apply to new university and go through the qualification process over. I would check again, before assuming it is your decision. I even know a case, where a 3rd year grad student at Yale was turned down acceptance into Berkeley grad school

What Happens When the Average Lifespan is 150 Years?

vossman77 life expectancy != maximum life span (904 comments)

While life expectancy has been consistently increasing in the modern era from 30 to almost 70 now, maximum life span has really not changed at all and stays at about 120 years. This true both for humans and laboratory rats, scientist are having difficulty increasing the maximum life span.

We are going to need a medical break-through in order to push 150 years, but it is a good thought experiment, I just don't see it changing dramatically this century.

Lego to Produce Three Box Sets Featuring Female Scientists

vossman77 vossman77 writes  |  about a month and a half ago

vossman77 (300689) writes "The Chicago Tribune reports: "Lego will produce a limited-edition box set called Research Institute, featuring three female scientists in the act of learning more about our world and beyond." After receiving 10,000 supporters on the LEGO ideas site. Creator Ellen Kooijman writes in a blog post: "As a female scientist I had noticed two things about the available Lego sets: a skewed male/female minifigure ratio and a rather stereotypical representation of the available female figures. It seemed logical that I would suggest a small set of female mini-figures in interesting professions to make our Lego city communities more diverse." According to LEGO, "The final design, pricing and availability are still being worked out, but it’s on track to be released August 2014.""

For-profit movie download sites threaten MPAA

vossman77 vossman77 writes  |  more than 4 years ago

vossman77 (300689) writes "No longer is bittorrent the enemy number one, the MPAA is now concerned about for-profit movie download sites. From the Reuters article:

Movie fans downloading free pirated films are no longer Hollywood's worst nightmare, but that's only because of a newer menace: cheap, and equally illegal, subscription services. Foreign, often mob-run, businesses aggregate illegally obtained movies into "cyberlockers" Cyberlocker-based businesses operate from Russia , Ukraine, Colombia, Germany, Switzerland and elsewhere. Hollywood movies are made available via illegal for-profit sites within days of theatrical release, while the advent of global releasing now allows the proliferation of individual titles into an array of language dubs within the first month of a theatrical debut, he noted. When movies are released on DVD and Blu-ray Disc, the sites upgrade the quality of video offered from camcorded images to pristine digital copies. "Sometimes these sites look better than the legitimate sites," Huntsberry said. "That's the irony."

For some reason, they also mention that the U.K. needs a DMCA even though the U.K. is not a problem in this case:

In the U.K., we are hamstrung by the fact that we have very weak legislation. However, the U.K. in April adopted the Digital Economy Act that mandates a so-called graduate response to cybertheft, similar to a plan used in France and elsewhere.

Just a though, but maybe, if they offered a low-cost, for-profit, legitimate download site without DRM, they could receive the profits and not the cyberlockers."

Hobbyist renewable energy

vossman77 vossman77 writes  |  more than 6 years ago

vossman77 writes "I was looking into renewable energy from a hobbyist perspective, maybe generating a few watts of solar or wind power, just to reduce my electric bill. But upon further review, I found out that I need a special grid tie AC inverter that shuts off when the grid turns off (for worker safety reasons) and makes the current in-phase with the grid. These two additional features over the cheap inverters sold at department store, makes the cost upwards of $2000, but support more watts than I need. While this is fine for large scale projects, it is out of range for a small scale hobbyist. A Google search came with some home brew hacks at best. So, are there any slashdotters out doing small scale renewable energy projects with grid tie systems? What are other options for the hobbyist to play around with renewable energy, other than charging a cell phone?"
