"But no one has been able to triangulate exactly where the broadcast is coming from." - How difficult and expensive would it be to build a system to exactly triangulate these stations? It seems if you had three receivers many miles apart and precisely synchronized, and you timed the signals at nanosecond resolution, then you could correlate and find the location within a foot. I'm sure it's much harder than that, but it seems with SDR you should be able to do much better than primitive triangulation based on approximate direction. Does anyone know how to do high-accuracy triangulation.

On a different topic... "If you drop a rock in this hole, it will take about a second to reach the bottom—whatever is down there is at least 32 feet below ground." - I've been thinking about high-school physics a lot lately so I feel obligated to point out that 1/2 A T^2 would be 16 feet.

A terrific article about cosmology, a field that contains a surprising number of unanswered questions and parameters without explanation. A candid cosmologist would say, as this article does in essence, "It's embarrassing what we don't know about the universe."

Meanwhile psychiatry and psychology, which don't even shape theories to be ridiculed and dismissed for lack of evidence, tell us in no uncertain terms that we're sick in the head and need drugs and/or therapy.

Quote: "... published studies report that about 25% of all U.S. adults have a mental illness and that nearly 50% of U.S. adults will develop at least one mental illness during their lifetime ..."

To me, the fact that half of everyone is now, or at some point in the future will be, diagnosed as mentally ill, calls into question the meaning of "normal". But maybe that's just me. And maybe the existence of official diagnoses like NOS (Not Otherwise Specified) is one of the problems.

Well. That's a relief. Certainly better than telling someone there's nothing wrong with him and sending him home.

One interesting thing I've noticed as a home depot customer is they don't require you to have a receipt for returns, as they can access all previous transactions based on your credit card number (... and therefore presumably have a centralized database which maintains a record of any credit card used at a home depot, hopefully in some hashed/encrypted format)
some of those phased out chemicals persist in the environment to this day

In ever decreasing levels. There aren't any that remain at the same levels as decades ago.

we don't really know what happens when parents who are contaminated with such chemicals have babies

Right. So we can hardly draw conclusions, now can we? "We don't know what happens" isn't an argument that proves something happens.

I have heard from people who believe that is a major connection there

There are people out there who will tell you anything. "People" is not an authoritative source.

> I've seen the Chromebook Pixel is 3:2, which is hopeful. But going with a machine that erases your installation when it loses power seems like a outright terrible idea (in addition to signaling Google that their locked down computing is appreciated in the least)

It does not erase your installation when it loses power. If you switch into or out of developer mode, it'll wipe user data, but otherwise your data is safe.

As for "locked-down computing", as long as Google continues to mandate developer mode as part of their hardware requirements, that seems quite sufficient to me.

POST-traumatic Stress: On Product API Ownership
This is just an excellent visualization to explain a concept that is hard to imagine.

Lots of difficult concepts are actually very simple once you boil them down to the fundamentals and visualize them.

This has big implications for education. Many concepts like derivatives in finance, algorithmns in computer science are suprisingly simple.

I remember a visualization for Paxos (a distributed consensus algorithmn) which basically have an actor to represent each node in the network. That was the moment I finally "got it".

It is a shame that educators are still so backwards at how they communicate concepts to students. and how ineffective that is. I think it comes down to the fact that professors in universities have to play dual role of being a researcher + to teach. And since they are recognized for publishing papers and not so much for making helpful visualzations to explain concepts to first year students. Education part is neglected.
I'm using a Chromebook Pixel running Arch right now. It works pretty well with KDE, and almost perfectly with GNOME, with the exception of­— stupidly— Chromium, which has pretty minimal high-DPI support.

If it's web facing can you be sure that you have taken reasonable measures to protect it (and not have a refund demanded or worse)?

Yeah...we talked a lot about this in the mid-80s with equal parts reverence for the audacity of the goals and Cold War-ish "Mr. President, we must not allow an AI gap!". This was when the Japanese "economic miracle" hadn't had it's bubble burst and we thought they were going to steamroll the US. I vividly recall one of the elder AI types finally stepping up and saying (paraphrased) "Guys...don't loose sleep. These guys are talking about things that won't be practical for 20-30 years, if ever. Get back to work.". Considering they were talking about commodity MPP computers, dataflow architectures, logic programming, deep machine learning, etc., he was pretty much dead on.

P.S.: Lest you think he was a true visionary, the AI kids went back to work on Symbolics Lisp machines, because we all knew that was the future of AI.
"But what do you use for search when you can't find it with DDG" is my question. (I do not work for the answer)
From the link you submitted:

Pesticide use in agriculture is down slightly, from 948 million pounds in 2000 to 877 million pounds in 2007. But that's only about 1% per year, and still close to a billion pounds of toxic chemicals intentionally introduced into the environment and our food supply each year.

So, just because it is down compared to some earlier period within the last few decades does not mean it is not historically unprecedented. I am talking on the scale of human history and how what we are doing chemically in recent decades is different from what was done for many thousands of years before that.

Some of the people I have talked to about such subjects have phd's and are published authors. I really don't think you are making a good faith effort to engage me here. So I think I shall bow out of this conversation at this point.
Sounds like I have some thinking to do. I've had this laptop for 5-6 years, and apart from the bad screen, the only fault is that the speaker started failing about a year ago (so I've been using headphones). Spend some time and effort fixing and upgrading this thing (new battery, screen, hunt for speaker issue, perhaps ssd upgrade?) or just go for a new machine?

One of the big bonuses to the thinkpads is that very complete user manuals are available free online, including exploded disassembly diagrams. Perhaps I should do the upgrade just because it's possible :)
For a lot of ingredients it's simply not going to be possible to follow exactly. For instance, suppose it calls for "1 jalapeno, chopped" - jalapenos will vary greatly in size and heat. Other ingredients will lose potency over time, so who knows how yours compare to theirs.

Another problem is that many recipes use the wrong metric for ingredients in the first place - most things should be done by weight, not volume.

But yes, in terms of cooking (as opposed to baking) one should never expect to follow a recipe exactly, no matter what. Everything should be tasted and modified to adjust along the way. Eventually one gets a sense of what those phrases really mean, particularly if you see the same person's recipes repeatedly.
This guy is a big fan of Samsung, despite the case cracking on his? Sounds like a range of laptops to avoid.

I have a Thinkpad T410, it has been very solid, I don't think there is one item that will physically wear out anytime soon, except for the power plug, which is larger than most brands, but has started to become loose. Oh for a magsafe power plug! Actually the little bumps on the trackpad are starting to wear off in the middle, but this doesn't seem to affect it's function.
> presumably have a centralized database which maintains a record of any credit card used at a home depot

That's a bit of a leap. I'd assume they just have a hash of the data.
Would need more qualifiers; do you want a big screen, minimum size+weight, etc?

I just got a "new" Thinkpad T530. It's a two year old model, but the last of the Thinkpads with physical mouse buttons, essential for using the Trackpoint. Got it for $550 with three year warranty after rebates; the specs are comparable to a current model. It takes up to 16GB RAM and supports up to three dedicated storage devices. In general Thinkpads run Linux very well. This was mainly for the larger screen, I saved enough I can wait for a travel computer in early 2015 based on Broadwell.
No, not really. MariaDB is completely dependent on Oracle and Percona. While they are doing some good work, they are by no means a complete and independent fork, nor do they have the resources to be.

MariaDB is also impacted by the lack of tests, they are absolutely not making replacements for all those tests, and they continue to pull code from upstream. So, same problem there.

Another happy 1Password user here. I've been using it for probably about 18 months now and I can never go back to manual account management. It took a bit of upfront time investment to migrate all my existing accounts into the tool but once that was done, it's been a pretty seamless experience overall.

There's browser add-ons you can use to auto-populate your login details that work well for most login forms with mostly no or minimal configuration required. It can get a little annoying when the login form has a CAPTCHA or some other non-standard requirement, but generally all that means is a few extra clicks. When creating new account details, configurable (e.g. length, allowed characters, etc.) password generation is built in.

You can keep your encrypted data store file on a cloud service for syncing between devices, should you wish. Which brings me to the 1Password mobile apps, which allow you to take your details mobile.

Probably the greatest friction point I've encountered has been when I'm on a foreign computer that doesn't have any of my 1Password support tools installed on it. In this case I usually just pull out my phone, navigate to the login details I need and enter them manually. But I take this as a small price to pay for markedly greater peace of mind.

I really can't recommend using a password manager enough. If 1Password is not it for you, then use some other password manager. But just use one.
You are 100% correct.

To add to this all syncing on 1Password is done using 3rd party vendors.

You can use dropbox, iCloud, Google Drive, etc to do the actual syncing of the encrypted files.

I agree with your reasons, but it's interesting to consider that realtime IM is one area that, while there exists a standard, simple, and scalable protocol that's been around for a long time - IRC - it's nowhere near as popular as the proprietary alternatives that followed. IRC usage is declining, and of the people I know, the majority have never heard of it. Yet almost everyone knows about email, AIM, MSN Messenger, and now Skype. What lead to this huge difference? Is it just the triumph of marketing client software, or is there something else?
Why do you assume every KeePass user is storing their passwords on a server somewhere? I would never send my password file over a network, and I don't consider USB storage "sharing."

I don't think so. No matter what shape the problem is in, there are always exactly n inserts and n deletes to the heap. Those are O(log n) operations, and there are 2n of them, so it's O(n log n).
Perfect example is Facebook. You don't have to be on it for them to know your phone number. If 2 of your friends have the "Share your Contacts with Facebook" option turned on, chances are Facebook has your phone number/whatever else your friends store on their friend about you.
are there any known vulnerabilities for 1Password?

Part of the problem with that technique is that the waves are effectively propagating in a waveguide (between the surface of the earth and the ionosphere). So the characteristics of the waveguide (such as the conductivity of the ground) influence the speed of propagation. It's certainly important for things like LORAN, and I'd be surprised if it wasn't for this.

Fragmentation, for the (security) win!
</sarcasm>

Not really, of course. The big win (shared by Windows Phone) is simply not turning on the security-sensitive cloud service by default. That being said, it is worth noting that enabling/encouraging third-party service competition can create an extra hurdle by discouraging cloud-service monocultures.
Are you sure that it's n log n? I think that the pyramid shaped configuration defeats this strategy by forcing the interval tree to report something on the order of n intervals with every query. So there are n queries on the interval tree, and each query takes log(n) + n time.

Also, something interesting to note that I was thinking about yesterday is that you don't actually need to use an interval tree for this. You can use a range tree instead, which is simpler (to my mind). You only need an interval tree to do a certain kind of query which we never need to do:

In Canada we adopted EMV chip debit cards years ago. It's worth noting that even when you switch to EMV, there is about a 5-year conversion period where vendors have to support older non-EMV cards. This is assuming all banks switch to EMV. Canada only has about 5 major banks and they all did it quickly but only recently are swipe-cards losing support.

Since it will take a while to be 100% chip-and-pin from both investment by banks and adoption by consumers, USA can look forward to debit and credit card breaches for a long time. So they'll have to invest heavily in information security, not just EMV.
