+ - 150 years of Maxwell's Equations->

Submitted by justaguy516
justaguy516 (712036) writes "Maxwell's equations are one of the most stunning discoveries in the history of human science. Its a unique story, both as a climax for a century of scientific observation as well as a compelling story of how scientific theory and practical application went hand-in-hand in building the edifice on which the entire world of 2015 as we know it exists. While most people think of Faraday, Gauss, Ampere and Maxwell, my favourite has always been Oliver Heaviside, that unsung self-taught engineer who made so many fundamental contributions to this field."

+ - Mystery of why galaxies always appear dustier on one side solved

Submitted by StartsWithABang
StartsWithABang (3485481) writes "If you look at a spiral galaxy face-on, the sweeping spiral arms and the central massive bulge are usually the most prominent features. But if you look at one tilted at an angle to us, dust lanes appear prominently. You might expect that the dust lanes should appear equally on both sides of the galaxy, but they don't. Even more puzzlingly, the dust actually does live in the middle of the disk, so you might think there's no excuse for this! We had a theory as to why this works for a while, but recent Hubble observations have confirmed this picture, and we've finally got our answer!"

itwbennett (1594911) writes "It seems these days like anyone and everyone can call themselves a programmer. But true software engineers remain a somewhat mysterious and exotic breed of tech worker. Here's a sampling of things we learned about them in 2014: Programmers from state schools get the best ROI on college, Alan Turing is the most important programmer of all time, and while Clojure programmers are the happiest, Java programmers earn the most."

Comment: Re:Federal Sentencing Guidelines (Score 1) 219

by Gazzonyx (#48472683) Attached to: Hacker Threatened With 44 Felony Charges Escapes With Misdemeanor

Federal sentencing guidelines almost never ask for "fully stacked" sentences. The term you're looking for is "consecutively." Most of the time, all sentences are served "concurrently," or at the same time. On rare occasions, as you write, a judge will specify that the sentences be served consecutively, to keep an exceptionally bad felon behind bars for as long as possible. Of course, the prosecutor can always threaten to ask for consecutive sentences to bulldoze the defendant into accepting a plea.

I've never considered this before, but isn't that a bit of "the law of unintended consequences"? For instance, if I know that I can commit a single crime now and pay the full rate or commit multiple crimes and pay them off in parallel, why deterrent is there for me to limit my activities?

I've always hated a law that I've heard of (this is strictly hearsay, I've never actually verified it) where in some parts of the US, if you involve a gun in a robbery there's an automatic minimum sentence which is in line with the sentence for having a gun and committing assault; just by having the gun you're already in as much trouble as if you used it, so there really isn't any incentive to not use it if you think doing so could allow you to avoid capture and prosecution. If you're going to be charged for attempted homicide, it's not like taking a hostage is going to add to your sentence at the end of the day and it has the most narrow chance of getting you off the hook.

My SO is a paralegal and I'm always amazed at the perverse incentives that are built into the legal system since you always seem to be in for a pound when you're in for a penny. No doubt legislation passed by someone "tough on crime", but the public seems to support it. I've always thought that putting someone in a place where they stand to lose nothing is a rather poor position to put them in.

For instance, I had lost my license due to unpaid tickets (I thought I had paid them all off, but I must have missed a payment) and I was pulled over for a taillight being out. At this point I now had a suspended license for driving on a suspended license (aka, strike two before they pull it for 5 years in the state I was then living). I went to a concert with some friends and they all hit the booze a bit hard and when it came time to drive home and they were all too drunk, we let the least drunk guy drive. It was more dangerous than the sober guy driving, obviously, but we reasoned that if we got pulled over the law would take it easier on a guy with a first DUI, a wife and a kid than a guy with a third violation for driving on a suspended license. The math was easy; I got "caught" (I didn't know I was doing anything wrong) a second time and they took my license for a year for the second infraction; your first DUI infraction is an automatic 1 month suspension or so. We knew which crime was "worse" in this case by what would have happened to myself versus what would have happened to the drunk guy that drove us home. We also knew which was safer, but it's not like the cops would have taken that into account, so it wasn't really a consideration in our assessment of the situation.

+ - Ask Slashdot: Can you M Theory with the Standard Model 3x3x3?

Submitted by genfail
genfail (777943) writes "Hey I was thinking, I think you can unify M Theory with the Standard Model if you we have 3 dimensions space, 3 time and 3 for gravity. 3x3x3
Nth dimensional time fixes the weird artifacts you see in the standard model that create things like dark matter to explain angular momentum of galaxies is even across the disk.
E=MC2 when taken as a whole also implies that time is a variable relative to mass, the more massive something is the slower time around it moves for the same reason that time slows down at the speed of light.
When taken into consideration it becomes apparent that angular momentum is not caused by mass that can't be seen but by the fact that time moves more slowly around a super-massive black hole at the middle causing the appearance of objects in the middle orbiting differently. So time and gravity both are being moved in three dimensions each.
What do you guys think?"

Comment: Re:Actually, this isn't how McDonalds corporate wo (Score 1) 720


Once they do sell you a franchise, they dictate your trade dress, which means corporate pays for remodeling the individual franchise stores (after all, McDonalds themselves owns the property), and when they tell you remodel, expect the crews to show up and just do it, you are at best granted minor choices on things like arrangement of the bathrooms, and the manager's office, and so on. Otherwise, they dictate. [...]

Everything you say other than this is true (former MCD shift manager here, but high school was a long time ago, so I may be mis-recalling). The corporation gives you choice of decor from the "catalog" (yes, there is basically a catalog for interiors) and then you split the bill with them 50/50 for the remodeling/upgrade. But they do tell you when you're going to be doing the remodeling and they do hire the contractors. Usually this also includes upgrades of the old/retrofitted kitchen equipment, which is expensive and provided by corporate approved suppliers only.

+ - Better free disk space monitoring?

Submitted by relliker
relliker (197112) writes "In the olden days, when monitoring a file system of a few 100 MB, we would be alerted when it topped 90% or more, with 95% a lot of times considered quite critical. Today, however, with a lot of file systems in the Terabyte range, a 90-95% full file system can still have a considerable amount of free space but we still mostly get bugged by the same alerts as in the days of yore when there really isn't a cause for immediate concern. Apart from increasing thresholds and/or starting to monitor actual free space left instead of a percentage, should it be time for monitoring systems to become a bit more intelligent by taking space usage trends and heuristics into account too and only warn about critical usage when projected thresholds are exceeded? I’d like my system to warn me with something like, “Hey!, you’ll be running out of space in a couple of months if you go on like this!” Or is this already the norm and I’m still living in a digital cave?"

+ - Early childhood neglect associated with altered brain structure, ADHD->

Submitted by vinces99
vinces99 (2792707) writes "Under the rule of dictator Nicolae Ceausescu, thousands of Romanian children were placed in overcrowded orphanages with bleak conditions and minimal human contact, a legacy that continued even after the 1989 revolution. Only recently have research and public concern caused policy changes.

University of Washington research on children who began life in these institutions shows that early childhood neglect is associated with changes in brain structure. A paper published this month in Biological Psychiatry shows that children who spent their early years in these institutions have thinner brain tissue in cortical areas that correspond to impulse control and attention. “These differences suggest a way that the early care environment has dramatic and lasting effects for children’s functioning,” said lead author Katie McLaughlin, a UW assistant professor of psychology.

Since 2000, the Bucharest Early Intervention Project has worked to document and treat the children’s health. McLaughlin joined the team about six years ago to focus on brain development. This study is among the first in any setting to document how social deprivation in early life affects the thickness of the cortex, the thin folded layer of gray matter that forms the outer layer of the brain. The study provides “very strong support” for a link between the early environment and ADHD, McLaughlin said."

+ - Is open-source more secure then closed source?->

Submitted by Meshach
Meshach (578918) writes "Interesting article about whether open source sofware is able to be secured against threats as well as closed-source software. Open-source advocates say they are more secure than proprietary software because developers are constantly fixing flaws found by users. The recent Heartbleed and Shellshock outbreaks vindicate this theory. Critics say the open nature of the software leaves it vulnerable to hackers because the programing flaws are out in the open for all to see."

+ - Supposed Battery Breakthrough. 70% charge in 2mins, 20yr life.->

Submitted by chaosdivine69
chaosdivine69 (1456649) writes "According to Scientists at Nanyang Technology University (NTU), they have developed ultra-fast charging batteries that can be recharged up to 70 per cent in only two minutes and have a 20 yr lifespan (10,000 charges). The impact of this is potentially a game changer for a lot of industries reliant on lithium ion batteries.

In the car industry for example, consumers will save huge on costs for battery replacement and manufacturers will save on material construction since they're using a nanotube structure of Titanium dioxide which is an abundant, cheap and safe material found in soil. Titanium dioxide is commonly used as a food additive or in sunscreen lotions to absorb harmful ultraviolet rays. It is believed that charging an electric car can be achieved in as little as 5 minutes making it comparable to filling up a gasoline based automobile."

Submitted by ZahrGnosis
ZahrGnosis (66741) writes "I'm in the midst of a rather lengthy job interview; something I haven't done for some time as I've worked as a contract employee with a much lower barrier to entry for years. Recently, I've started patenting some inventions that are applicable to my industry. One hope is that the patents look good to the prospective employer on a resume, but I don't want them to take the existing IP for granted as part of the deal. I'm worried I have the wrong attitude, however. My question is, how should I treat licensing of the patent as a topic with respect to the topic of my employment? Should I build the use of my patented ideas into my salary? Should I explicitly refuse to implement my patented IP for the company without a separate licensing fee? If I emphasize the patent during the interviews without the intent to give them the IP for free,is that an ethical lapse — a personal false advertising? At the same time, when I work for a company I feel they should get the benefit of my full expertise... am I holding back something I shouldn't by not granting a de-facto license while I work for them? I perceive a fine balance between being confrontational and helpful, while not wanting to jeopardize the job prospect nor restrict my ability to capitalize on my invention. Thoughts?"

What I cannot find is any "Best Practices" or "Lessons Learned" out there. So I ask you fine folks: What are some of the best and worst designs, practices, procedures, and work flows that you have encountered in sitting down to stage anywhere from 2 to 200 devices at once to get configured?"
