Why, oh why do I always click, "Post Anonymously"? Seems I get far more +5s as an AC than as meself. The mods stop at +3 when I'm posting under me own name!

Interesting fact: It depends on where you look at your posting and whether or not you have "Excellent" Karma.

There are two ways to look at your posting: From the article's comment section and from your own comment history on your profile.

If you're an AC, your comment gets a nifty 0 moderation. People need to upmod you 5 times until it's at +5.
If you're logged in, you get an immediate +1 that is visible to you and everyone. People only need to upmod you 4 times until it's a +5.
If you have "Excellent" Karma, you get another +1 putting your posting at +2.
... ... but that one is only visible on the article's comment section. In your own history, it will appear as a normal, regular +1 posting.

Since people stop moderating when a comment reaches +5, your own history will never show them as more than +4.
If then someone downmods it only once shortly before the thread is archived (and moderation gets closed), your posting will sit at +3 in your history forever ... even if the article lists it at +4.

You see, you don't even need Slashdot Beta for the posting system not to make any sense. :-D

+ - 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."

+ - Ask Slashdot: Handling Patented IP in a Job Interview?

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?"

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."

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."

As others have pointed out above and before: Passphrases are neat and easy to remember --- but a nightmare to type.

There is no functional difference between typing X letters of a word, or X letters of random garbage once memorized. Indeed, I would rather argue that the (almost) random garbage is probably faster, since you could choose it for maximum typing comfort/speed, like more strongly alternating hands for typing and avoiding "distant" key combos, without greatly compromising entropy.

Now, add to this that words in almost all languages follow a nice pattern: Consonants-Vocal-Consonants-Vocal. Usually with a 1.5:1 ratio of consonants to vocals. So your actual entropy for pure word-length compresses down by a similar factor.

So, in difficulty of brute forcing (if the attacker knows you chose either garbage or words) 10 letters of random garbage equal about 15 letters of regular words; give or take a few characters.Add to that the speed argument above, once you've memorized them

This means that a passphrase gets more secure only after it has already become far more time consuming to type.

Finally, at some point (currently at about 10-16 chars, depending on the algorith), it becomes easier to break the password hashes by finding collisions that to brute-force the password.

So congrats for your passphrase having 2000 bits of entropy, when it still only takes 15 minutes to find a SHA1 collision against your password.

I have to type my password 100+ times a day. I can touch-type, but one typo usually means I have to delete it all and start over.

It's really hard to get Ctl+Alt+A wrong.

Try doing that in an SSH login shell. Or in a textual DBMS management console. Or in a general CLI tool that expects a password. Try it in a computer game that uses its own home-brewn dialog boxes.Or, do it in a text box that does not echo out characters, hiding the length of the password. Or password boxes that disable highlighting entirely.

Now do it, while knowing that you get locked out for 15 minutes when you enter the password wrong once or twice.

There are many situations in which the only way to recover safely from a typo in a password entry field is to hit backspace a few times.
