Clarificiation on the IP Address Security in Dropbox Case

pz Relevance? (141 comments)

Someone, who has no apparent power, wants to correct a judge. Just because they think they're right and the judge had inaccurate reasoning, despite coming to the same conclusion. (There's a good XKCD comic on the subject of correcting people in the Internet.) The critic's opinion will carry no legal weight. The same critic has a history of proposing long-winded, half-baked ideas to correct issues he sees with various societal inefficiencies that have gone no-where. I'm not going to waste my time.

Would someone be so kind as to please remind me how we can block posts from a given author?

Debunking a Viral Internet Post About Breastfeeding Racism

pz Re:Seconded. (350 comments)

You forgot to mention that he has an embarrassingly small sample size and doesn't do any sample correction. He doesn't publish any significance values, so we have no way of knowing if 70% is the same or different than 77%, to the accuracy of the methodology (as well or as poorly thought out as it may be). Then he considers 86% and 67% to be about the same, and subsequently 63% and 79% to be about the same.

I am not a professional statistician -- I hire people to do that sort of work for me when I need definitive answers because I don't know the details. But I know enough to recognize handwaving, and that's all the long-winded original posting is.

It's Time To Revive Hypercard

pz Balance taxes? (299 comments)

I've never balanced taxes. Is this a new thing?

Oh, you mean balance checkbooks and pay taxes. There's much better software to do that these days.

And there are much better ways to teach programming. For a very long time there has been a movement to bring programming to the masses, as if, somehow, everyone would be able to write beautiful, intricate code to solve their most complex problems. Most people can barely match their clothing (note to the reading-impaired: that was hyperbole); why should we expect them to be able to write code?

Writing programs requires clear, linear thought. It requires thinking in terms of structures and systems. The push in the greater population has been toward valuing non-linear thought (although that baffles me), so there's a big mismatch to overcome. Yes, there are plenty of graphical programming languages that reduce the need for precise syntax, but they only REDUCE it, not eliminate it, and they still require procedural thinking which, ultimately, presents an insurmountable difficulty for many people.

Not everyone can or should be a programmer: Not everyone is a writer, Not everyone is a photographer, Not everyone is a painter. Sure, everyone should be given basic skills in writing, and perhaps in drawing or painting as a child, and so perhaps everyone should be given basic skills in programming, but beyond that, why? Not everyone is able to understand calculus; why should we automatically expect that everyone should be able to write Java, Python, or whathaveyou?

How Apple Watch Is Really a Regression In Watchmaking

pz Re:cell phones and notepads (415 comments)

I always have my appointment book with me in my briefcase, right next to my laptop and phone. When I'm in my office, it's open in front of me. The only time that it isn't nearby is when I've intentionally left it aside.

My scheduling isn't as interdependent as yours. Meeting times are negotiated via email. My schedule has only 2-3 meetings per week, and most of the entries in my book are for allocation of time to work on one project or another. Perhaps it also helps that I'm the boss.

Use the right tool for the job -- for your application, the best tool appears to be electronic. Not so for mine.

How Apple Watch Is Really a Regression In Watchmaking

pz Re:cell phones and notepads (415 comments)

Pen and paper have some very serious advantages that should not be overlooked when distracted by the new and shiny. Use the right tool for the job.

Personally, I keep my appointment book with paper and pencil. I can access it anywhere, at any time, whether or not I remembered to bring a charger, whether I'm on a plane or in a meeting (and in a meeting, no one can accuse me of playing with my phone instead of paying attention). I also keep a personal journal in acid-free paper and fade-resistant ink so that my grandchildren can enjoy learning about me when I'm long dead and hold a cherished physical object that I held, just as I have enjoyed learning about my grandmother decades after she passed away, and cherish being able to touch something she touched.

But, the right tool for the job also means that I do most of my writing electronically, often switching between multiple virtual desktops. I keep my phone book electronically (although I do periodically dump to printed paper for disaster recovery). My most recent publication will only be made available in an electronic version.

New does not automatically mean better. Use the right tool for the job.

Detritus From Cancer Cells May Infect Healthy Cells

pz Re:How is this different from a virus? (46 comments)

And that should have been part of my posting above that asked the question -- these fragments dock with other cells, inject the RNA, and that RNA causes the cells to become cancerous, which, in turn creates more of these little RNA capsulettes.

I'm sure there are some differences between these and classical virus structure, in some way, but given my ignorance of the subject, they walk and talk like viruses.

Incapacitating Chemical Agents: Coming Soon To Local Law Enforcement?

pz Re:A tragedy, but stretching the bounds of relevan (152 comments)

It wasn't the chemicals, as you point out, but the penetrating object that killed her. She bled out. If she hadn't bled out, she would have likely suffered severe brain damage as skull and projectile fragments entered her cranium.

The relevance being, also as you point out, that shooting anything into the face is a bad idea when non-lethality is the intent. But any chemical that is going to be delivered in such a way has exactly that potential, as do rubber bullets (have you seen what those do? non-lethal does not mean non-damaging).

Any chemical means to convince a highly agitated crowd to cease and disperse is going to have extraordinarily strong effects, even when used correctly, with some suffering the effects more than others. Some fraction of the population is always going to be sufficiently vulnerable for lethality.

Ultimately, I think we're agreed: The very idea of a non-lethal chemical weapon is absurd.

No More Lee-Enfield: Canada's Rangers To Get a Tech Upgrade

pz Re:May I suggest RTFA? (334 comments)

Thank you for that very clear and succinct assessment of my intellectual capacity after reading a full paragraph of my writing. Touche. You perfectly hit the nail on the head. I am totally and utterly lacking in intellectual capacity, despite any evidence to the contrary.

Now, if you'd care to engage in a rational debate without ad hominem attacks, I'd be happy to respond. If not, please go away.

No More Lee-Enfield: Canada's Rangers To Get a Tech Upgrade

pz Re:May I suggest RTFA? (334 comments)

My guess: Someone has been promised kickbacks and incentives, and the choice of a replacement has already been made. It will now be followed by a circus to "determine" that it's the best choice. And it will end up costing the tax payers a fortune. I.e. a smaller version of the F-35 scam. Follow the money trail.

DING, DING, DING! And we have our winner! Money and votes are the only motivations here. Nothing else makes sense. Money, some manufacturer is going to get a juicy multi-year exclusive contract. Votes, some MP is going to be able to say, "look how many jobs I brought into our district!"

Ask Slashdot: Why Can't Google Block Spam In Gmail?

pz Re:Juggle multiple gmail accounts (265 comments)

More GMail tricks, that may help you: when you have account

someaccountname@gmail.com

all email of the form

someaccountname+anysuffix@gmail.com

goes to your account. The plus sign is a literal character, not a concatenation operator. The only downside to this is that some email validation suites don't allow plus signs in user IDs, even though RFC 5322 allows them. Sometimes I use the format

someaccountname+onlinestore@gmail.com

when giving my email address to OnlineStore.com so that it's clear from where particular messages should originate.

Too Much Privacy: Finnish Police Want Big Euro Notes Taken Out of Circulation

pz Re:To their defense (314 comments)

In contrast, as a normal person, I've used EUR 100 and EUR 500 bills regularly to take care of, well, large transactions that need to be confirmed and delivered faster than a bank transfer would allow (and when the people involved rile at paying 3% for credit card fees, or aren't set up to take credit cards in the first place), like paying vendors, or hotel bills outside of big cities.

Ask Slashdot: Why Can't Google Block Spam In Gmail?

pz Re:You vs everyone (265 comments)

But GMail does, to my understanding, use a personalized filter, in addition to the global filters. I get some legitimate email in a foreign language (not Chinese, but one with a non-latin alphabet), and some spam in that language as well. GMail gets them 100% right. Alphabet is just another feature that you perform Bayesian analysis on.

What any big message processing service has that a single user won't, is access to the content of messages across users, and the collective action by its users. So, for example, if a new spam campaign starts up, once the 10th (or so) user has clicked "this is spam", the rest of the recipients' versions of that same message get automatically re-classified. I used to be responsible for fighting spam at a mid-sized social networking site (that no longer exists, unfortunately), and believe me, simply looking for multiple copies of a given message is a strong tool for fighting spam. The back-end service operators get access to that, the users don't.

Ask Slashdot: Why Can't Google Block Spam In Gmail?

pz Re:WTF? (265 comments)

I have found that essentially every time I give my email to a legitimate retailer, they automatically assume that this means they can send me marketing email on nearly a daily basis. However, most retailers also honor the unsubscribe requests, and if you are vigilant about clicking through unsubscribe and marking real spam as such, GMail does a really very good job. Also, I've found that when I unsubscribe to lists that I really don't read (including marketing email that I might have thought could be interesting but no longer want), the total volume of spam goes down.

I cannot explain the OP's experience, as it runs completely counter to mine.

What Will It Take To Run a 2-Hour Marathon?

pz Re:Wind, not still air. (254 comments)

A course in a large C shape then with two short arms 0.25 of the distance, and a long middle arm of 0.5 the distance, with prevailing wind down the long arm. Start and finish are 0.5 apart. Extra runners act as a wind shield on the appropriate side during the short arms, and the record challenger has the wind at their back for the long arm. Might work.

I'm curious about the assertion that start and finish have to be so close together. That's certainly not the case in Boston, one of the most famous marathons in the US. Do race times established in Boston not count for world records?

Now that I think about it, it wasn't the case in the Athens Olympics either. Those are the only two races that I'm personally familiar with. Which courses meet that start/finish requirement?

What Will It Take To Run a 2-Hour Marathon?

pz Wind, not still air. (254 comments)

The summary implies that the front triangle of runners will be necessary to cut the wind generated from the athletes running through the air, and thus, that the air is still.

Wind at the runners' backs, on the other hand, obviates that issue entirely.

Also, just above freezing is probably too cold because it requires extra clothing (and thus weight) to protect the extremities. Ideal running weather is in the 50s F / 10s C.

The summary further posits that a flat, straight course is best without citing any evidence. Do we know that sustained, constant exertion is more efficient over a two hour period than exertion that has a cyclic component? Yes, a course that has gentle ups and downs will probably take more energy to run (as the runners need to lift themselves up each hill, and don't generally get that energy back), but is there empirical evidence that it will always be slower? Consider the extreme of a course that starts out at a higher elevation than it finishes, but is strictly linear in altitude between the start and finish lines. It will surely be faster than a straight, flat course without any change in elevation.

The limiting factor, it would seem to me, is that the ideal course to minimize speed has not been constructed.
