Parents Investigated For Neglect For Letting Kids Walk Home Alone

Parents Investigated For Neglect For Letting Kids Walk Home Alone

xeos solution: religious protection (778 comments)

It seems like >95% of the posts here are in support of the parents. The next logical question should be "what can we do about this"? Sure, there are political avenues, but those are slow.

I think there might be a much faster way - we already have a special class of people who can mistreat their children by most of societies standards and get away with it - I'm thinking here of the Christian Scientists who deny almost all medial treatment to their children, and the Jehovah's witnesses who deny a smaller but still measurable subset (anything requiring blood transfusions).

If you can use religious freedom to justify clearly life-threatening decisions for your children, then I suspect so called "free-range parenting" could also gain protection given the right scripture. Perhaps the religion that offers this already exists; if not it shouldn't be so hard to create....

2014 Geek Gift Guide

xeos Re:The best gift? (113 comments)

Agreed. I thought maybe this piece would be interesting because it would feature interesting gear rather than poorly thought out opinions and commentary. But apparently he can't even choose interesting gifts let alone solve mildly difficult real-world problems.

I'd use slashdot beta if it offered Haselton free reading.

The One App You Need On Your Resume If You Want a Job At Google

xeos Matlab is not elegant, but it is useful (205 comments)

I've used Matlab for 10 years. I do not enjoy its syntax, but it's fast at what it does (matrix math) and has a huge library of tools built in that are also quite fast. It's also very cheap for academics, which is why it has such a stronghold there. People who say "switch to C or Python" for huge immediate speedups rarely know what they are talking about - they only projects I know of that tried that found that their code (again, matrix heavy) ran slower, not faster. With a lot of optimizing and the right libraries, yes, it is possible. But for most Matlab users their time is mostly spent developing, so that would be a poor tradeoff.

It's much more pleasurable to write or read python (or lisp (or smalltalk)) code, but you lose the kitchen sink. Here's a quick example: printf. Yes, it's ugly. And takes a little while to learn. But, it's very good at formatting text, and has all the options you need, want, or will ever want. Well, matlab is a language filled with printf style functions for every kind of data visualization you could want.

That said, TFA sounds like a load of crap. Anybody in google want to share what really goes on? I'm sure it depends a lot on which group you are in - machine vision and AI surely use a lot of matlab, whereas search probably never heard of it.

Link Between Salt and High Blood Pressure 'Overstated'

xeos Re:The reason why you're told to cut salt for high (291 comments)

That's a nice theory, but none of the primary literature I've read on this topic, or review articles, have ever suggested that it was misdirection. Perhaps that's how your prof justified his behavior, but I don't think it is what most Dr's think they are doing.

Link Between Salt and High Blood Pressure 'Overstated'

xeos Re: I can simply ignore all health and diet advice (291 comments)

Clever!! I do wonder what good use they could be put too, though :-) Nicotine is actually a pretty fantastic insecticide, though there is some concern about the bees.

Link Between Salt and High Blood Pressure 'Overstated'

xeos Re:Personalized medicine... and nutrition (291 comments)

I would argue that we never really knew that fat was bad for us - it was a hypothesis that got converted into policy before the empirical evidence that could have lead to actual knowledge was ever collected.

Link Between Salt and High Blood Pressure 'Overstated'

xeos Re:It's a small study (291 comments)

About as many studies find a decrease in blood pressure with increased salt intake as the reverse. So the number that find the high salt=high bp link isn't really that informative.

Link Between Salt and High Blood Pressure 'Overstated'

xeos Old news, really (291 comments)

The link between salt and blood pressure is pretty clearly not the one your Dr. tells you, and this has been known for a really long time. Even the first study to show the "link" turns out to be bunk science:

http://www.stat.berkeley.edu/~...

More recent meta studies have shown that about as many papers find a positive link as a negative link between blood pressure and salt - yes, eating more salt can lower your blood pressure (or, more likely, it's all just noise). Look it up on Pubmed if you want to read all the details. It's a good skill: you'll quickly learn more than your Dr. does about any topic of real concern to you, unless your Dr. is a specialist or obscenely good at his job.

What's sad is that simple to understand explanations that lead to simple to follow prescriptions (ie eat less salt) tend to stick around way longer than the scientific consensus behind them.

Slashdot Asks: Should Schooling Be Year-Round?

xeos Re:Public School Is Wrongful Imprisonment (421 comments)

It's called home schooling. And often there isn't that much schooling going on, and yet the kids do way better than in public school. A low bar, I know.

Ask Slashdot: Linux Login and Resource Management In a Computer Lab?

xeos A lot of complexity, a little gain? (98 comments)

That sounds like a lot of overhead for a problem that seems unlikely. I've used lots of multi-user linux boxes over the years and never noticed that a few bad users ruined the experience for everybody else. If it's really an issue, think of it instead as a learning opportunity - post concise instructions on proper lab utilization and how to use top, etc to check if somebody else is the reason why the machine you are using is slow. Then let users police each other.

Ask Slashdot: What Good Print Media Is Left?

xeos Re:The Economist (285 comments)

I find the Economist to be much higher info density than any other print magazine I've looked at recently. Not a long list I admit, but still I'm shocked you would say it's low density. Maybe you just aren't interested in the content.

Meet the Diehards Who Refuse To Move On From Windows XP

Meanwhile 7 seems a good bit less stable and rough around the edges. Haven't tried 8, but all signs point to it being much worse.

Meet the Diehards Who Refuse To Move On From Windows XP

xeos Re:Wrong way of looking at it (641 comments)

Having switched to Win7 for my home machine and still using XP at work, I have lots of opportunities to compare and contrast the two oses. 7 brings a few small improvements in the start menu and windows explorer, and some minor bugs. The improvements are not nearly enough to justify the time and cost to upgrade machines that work just fine. If WinXp was still supported I'd guess we would still see 30% of PCs running it for years and years after today. Even more if it were still sold.

Datacenter Gives Internet To 70 Percent of Navajo Nation

xeos That's $1483 per household/business (162 comments)

Seems like a lot to me. I tend to think that (1) it could have been done a lot cheaper (wireless?) and (2) if in fact it had to cost that much, then the money probably could have been spent better.

Let Big Brother Hawk Anti-Virus Software

xeos I wouldn't pay $10 (405 comments)

I've been on the internet since the mid 90s, and never ever detected a virus on my machine, other than in un-opened email. Email used to be a big source of viruses, but these days ISPs use scanners just as up to date as anything I could buy. A little common sense is all it takes to be virus free. This libertarian would not support your plan - I see little advantage to having everybody install anti-virus software.
