Keep using it. You can't just wake up in three decades and decide that you should still be able to be active. You have to keep using it week after week, year after year.

Find something you like to do. Do it regularly. You can keep getting better (more skilled even if not faster) for a long time.

Sometimes you'll get an injury. Rehab it, and get back to doing whatever it was that you enjoyed. It may take a year to get back to where you were. It may hurt. Do it anyway. Do what you don't want to have to do for a year (if it takes that long), so that you can do what you want for several decades.

That all said, know your limits. If you try to crash through them, bad things happen. (I still remember the lecture from that one physical therapist...)
U.S. delays 'incentive' airwaves auction to early 2016
In a recent interview at Stanford, Matt Rogers (co-founder of Nest) explains the Google/Nest relationship. Basically, they needed a bunch of $$$$ to get to the next level and they wanted Google to buy them and fund it rather than raise a huge round.
I think they are putting a little too much of the blame on Wiedeking here. The CEO doesn't make huge stock purchases like this without board approval, and Piëch was on the board of both Porsche and VW. To me it sounds a lot more like a play by Piëch all along.

The article also understates the rivalry between Porsche and VW. They're saying it's just Wiedeking behind it since '93, but it's really been going on for a lot longer as far as I know.
Libraries, such as mpfr, that implement multiple-precision floating-point arithmetic are completely standard. At best maybe you can argue that it introduces extra programming work over regular doubles, but in Mathematica it is no work at all as it has an arbitrary-precision floating-point type.
Samsung releases SSD Magician for Linux
Shameless plug, but my startup Xendo (http://xen.do) connects into Google Drive, Evernote, Dropbox etc. and provides a single search across all of them. You can 'pin' content so team-mates will see specific items promoted to the top of their results if they're relevant to their search. Let me know if you're interested in following up.
I really like how Elon Musk thinks big and acted on it :
"..get us back on track of extending life beyond earth, that’s the reason for starting SpaceX" (51:43)
I understand your point and agree to an extent, but teaching an orangutan to do calculus would not require you to break the laws of physics, so that comparison wouldn't really work.

What would blow my mind is the discovery of a "spigot" algorithm for the game of life, i.e. it would calculate generation n for a particular starting state without having to compute intermediate generations.

Well, they did trade it out of sample, so that probably means the model wasn't overfit. But, I agree, they probably used unrealistic execution assumptions
... or does Greenpeace have a clue what they're talking about?
Awesome, glad to hear you've been able to find a balance. Sounds like a big part of that is your shared interests in these areas with your wife which allows you to focus the time there.

Out of curiosity, how much technical knowledge was needed for the CNC mill?
Maple isn't quite as much of a black box as Mathematica. Many of the library functions in Maple are written in Maple and you can easily read their source code.

Unfortunately, yes. The linked article even avoids this language at all costs. And that's just how people work in physics and engineering. They want to talk about spinning functions and all this nonsense instead of just doing some basic linear algebra.
This sounds very much like the stories that Paul Devereaux (https://en.wikipedia.org/wiki/Paul_Devereux#UFOs) collected and analysed in his books.

I like his work because he takes the scientific approach: the evidence is that we see lights in the sky. Start from there, assume nothing, and see where the evidence takes you. He's a breath of fresh air compared to the wacko UFO stuff you normally read.

One of may favourite nuggets from him is to look at the whole UFO thing as a cultural phenomenon. Don't doubt people, but listen - properly - to what they are saying, and look for patterns. He did this and looked at the standard taxonomy for UFO sightings (https://en.wikipedia.org/wiki/Close_encounter), but focused on the exceptions. He found lots of stories that didn't fit the standard model e.g. a woman who had seen a humanoid figure just floating in the air for around an hour near sunset before disappearing. No good explanation for that in terms of aliens, so he looks further afield into various elements of human psychology and geophysics.

In the end, he seems to settle on the idea of a long term geo-physical phenomenon, which may be linked to the earthquake lights thing (https://en.wikipedia.org/wiki/Earthquake_light). He posits that this might interact with human consciousness via the very strong magnetic fields that you would expect if such a phenomenon were to occur (perhaps with other mechanisms too). This would explain the varying effects from weak (lights in the sky) to strong (weird hallucination-like experiences), depending on how close you are to whatever is going on.

Sounds like a good way to tie all the stories together, especially given that as he points out, UFO stories are quite recent, but other cultural stories with almost identical characteristics e.g. faeries, angels, etc are pretty much universal, so may be the same phenomenon interpreted differently.

OTOH, evidence is hard to come by and this is definitely fringe theorising. Interesting reading though, and very thought-provoking.
The fact is anyone can *Predict the price of bitcoin, but will you actually put your own money to trade?

If you understand the "what" deeply, then the "how" is trivial. The decomposition is in the sense of an orthogonal basis, and so to compute the transform you just do a dot product in the relevant vector space.
It doesn't work on SSL yet. Although I won't be surprised when in the near future certain carrier-enhanced phones start coming with a Verizon-signed root CA installed that enables them to crack into your SSL stream and do the same thing.

As for its legality, it shouldn't be, but it likely is. After all, it's well established that ISPs may mess around with your TCP and IP packets to enable NAT. So why not with the HTTP stream?

I think nowadays it makes a lot more sense to use a pure cellular connection. When I had my system installed, I initially got a phone line installed just for it, but then the monitoring company pointed out that the monthly cost of my POTS line was more than the monthly cost of the data-only GSM connection. I'm not particularly worried about macgyver burglars snipping my alarm wires, but now in order to disrupt it, they'd either have to jam the GSM signal or locate the controller box (which is locked up) and rip the antenna off.

Re: your comment about your insurance company not recognizing a homebrew security system, all I've got to say about that is that I don't care how good a coder you are, being the sole QA person for your house's security system is probably a pretty miserable experience. :)
Perhaps manufacturing processes like laser sintering or 3D printing with a MIG welder have not become mainstream because traditional metalworking processes like casting, turning, and milling are so much faster and much more repeatable. Let me know when this thing can hold tolerances of +/- 0.0001". We'll probably have a cure for cancer by then.

Metal can be a tricky material to work with. It takes a lot of force manipulate. If you don't know what you are doing, you can very easily get seriously injured or even killed. To me, it would seem much more rational to try to build low-cost milling and turning centers that are small enough to move into a house without taking out the walls and simple enough to maintain where you don't need to have certified mechanics come every time you crash it. You're still going to have to make a considerable investment of time to learn how to safely and properly operate it, but that seems much more realistic scenario than emailing a file to grandma, having her put on her sunglasses, then pressing "Print," followed by 6 hours of sparks flying.

Don't get me wrong, I'm sure there are applications for additive metal manufacturing processes, but I believe that the cases where they are the best solution are few and far between.

So, I suppose this means that ads that Verizon customers see are potentially targeted by their home address, age, gender, and call/texting patterns.

Holy shit, if I was a customer that would be ending today, even if I was in a contract, I'd say they pretty clearly are in breach of contract over my privacy expectations, by sharing who I am with every website I visit.
Polymer – Welcome to the future
> When times get tough, those without credentials usually seem to be the first to be ousted.

I have seen those without credentials having a harder time finding work, but I don't see why they would be the first to be ousted. Credentials are great for making the first cut in applying for a job, because they have to make that decision with relatively little time and effort. Credentials are also great for applying to companies that have little trust in their ability to interview candidates, but after you have been there for a while, they know what you can do. It doesn't make sense to get rid of people based on lack of credentials (and I've never seen it happen).
Nobody never said they would be. However, their market share is notably smaller (and the operating systems they run on is vastly more diverse), and thus there's little sense in writing bulk malware targeting them. Targeted attacks definitely, though in that situation one would be screwed almost certainly anyway if the adversary is capable enough.
Yikes. I use them both for their AWS service and as a consumer of their ecommerce side. I don't do much with their Prime programming, but I have a membership. There are a couple of areas where Amazon got worse since 2012 on the ecommerce side. First, Add-on items are annoying. Stuff I used to order and get for free now has to be bundled. I get why they are doing this, but it's just jarring.

Second, their prices actually seem to be getting higher. I can often now find equivalent products cheaper locally. Tools are especially bad that way: Home Depot regularly beats them. Clothing is a crapshoot, but I generally find better sales at local stores as well. Amazon will typically have the best of breed item, while not having a basic version for a reasonable price. For example, last winter I bought winter gloves. Amazon had great ones, with good reviews, etc. but I bought a pair for 80% less that while not as good was very adequate. I checked later and Amazon did not carry this brand or much decent stuff at this price point.

Search is getting worse. More products are miscategorized and you have to be very careful about what you buy. Here's a quick example, search for "GoPro". You'll get many duplicate options, often with confusing descriptions, in different departments, etc.

They are still a powerhouse when it comes to online shopping, but I really wish someone gave them a kick in the ass in terms of pricing and usability.
It depends on what you are trying to accomplish. Multiple precision integers are not necessarily slower than multiple precision floating point numbers. And if you're doing pure math research, chances are that you do care about results being provably correct, in which case the much simpler semantics of integers is a great advantage.
Your audience isn't your social network
And pretty much most of these exploits are targeted attacks already.
Very true. I could warrant spending $5 for 10 minutes of a plumbers time to save hundreds on a DIY job, I can see the value in something like that. When you think of it that way, it actually makes a whole lot more sense, but I feel like it goes outside of the realm of what most people would describe a Q&A platform, it was more akin to a consultancy application.

Getting a plumber to offer up their time for such a small amount of cash? That will be the difficult part. Getting anyone who's primary occupation does not involving working at a desk like an electrician, mechanic, plumber or carpenter to use this service for pennies will be very difficult.

I know a plumber and he runs his own business here in Australia, I think his hourly rate is about $85 an hour. If you take his hourly rate and break it down to a per 10 minute cost that is about $14 (rounded down). Presumably of this $5, Fountain will take a cut and the result might be somewhere around the $3 to $4 mark that an answerer will actually get.

If something like this does work, I will without-a-doubt use it and in turn, try and make some money on the side answering programming related questions and helping people stuck on coding related problems.

As someone who has done lots of work with floating point, I disagree. My fear (or more properly caution) with floating point includes tricks like if you are going to add up an array of floating point numbers, you need to sort them first. The experienced floating-point programmer will know what order you need to do this in.

The inability to represent 0.1 properly in binary floating point is not a problem solved by increasing the precision your floating point library.

Also, there can be be surprising cases where single-precision might not be enough. For example, if you are going to represent exchange prices for, say, futures, you need to take into account that some of the price increments are in pennies, some in fractional dollars. You need the calculations to be reversible, and to have enough precision and accuracy to represent the whole range of price increments and expected volume.

One example of a lack of appropriate paranoia about floating point numbers was the i'm-not-very-good-at-writing-parsers' author of ASP and the result was http://www.exploringbinary.com/php-hangs-on-numeric-value-2-... denial of service to all unpatched PHP sites. Also bit java.

Note that interesting prime number work depends on integers and won't work with floating point. Including factoring large numbers in cryptography.
What is all this talk about exploiting? Were the workers forced to work? If so, why pay them at all?
I find it fascinating how technology changes the definitions of words. I heard a speech by Zuckerberg once that began with the phrase (paraphrasing) "The world has never been more connected than it is today." If you had asked someone 100 years ago what 'being connected with someone' means, I imagine the answer would be something very different from the one Zuckerberg (or most people today) would give.

When did you perform that verification? I know they started out by hosting storage chunks on AWS and Azure in 2011, but they have massively increased their own data center capacity since then.

Michio Kaku says: "Lets say we have an ant hill in the middle of the forest. And right next to the ant hill, they’re building a ten-lane super-highway. And the question is “Would the ants be able to understand what a ten-lane super-highway is? Would the ants be able to understand the technology and the intentions of the beings building the highway next to them?"

The chance of higher civilisations being all around us, but us being too primitive to perceive them is my favourite explanation.

Poland is using the strategy of "Showing Teeth" - which means that it is doing everything to actually make any country think twice before attacking.

Having huge stockpile of artillery and armoured vehicles it is very difficult enemy to have.

Recognizing this as perfect way to deter enemies (mainly Russia) Poland have been investing resources on growing woods (for hiding) and developing newest artillery and "hit and run" vehicles and equipment.

You would be surprised what they have in development at the moment.
After all - Poland just started huge shopping spree - they started enormous arm up project, so we will see more of those ultra high tech stuff showing up soon.

Yes, seriously. Assange himself stated bluntly that he told Snowden to go to Russia (not Cuba, nor any of the leftist South American nations).

DDB left WikiLeaks due in part to the ongoing association of WikiLeaks with authoritarian figures like Israel Shamir.

WikiLeaks could choose to start today and bring "transparency" to an increasingly opaque Russian situation, especially since Russia has recently passed laws requiring all media outfits to have no more than 20% foreign ownership, passed laws requiring bloggers to register themselves with central authorities, passed laws legalizing Internet surveillance even more extensive than is legal in the U.S. (and even U.K.) and much more.

WikiLeaks could do this today, there are half a million civil liberties organizations in the Western world focusing on the Western democracies and seemingly no powerful groups in Russia.

But despite their stated pro-transparency aims, WikiLeaks refuses to do this.

If it's because Russia has threatened WikiLeaks with actual physical harm (something the U.S. government has never done) then WikiLeaks shouldn't have acted as collaborators with Russia by telling Snowden to go there instead of South America.

But I don't think it's a physical threat at all, the cooperation of WikiLeaks with Russia since 2010 has gone on for so long (and Assange has been cooped up in Ecuador for so long) that one would think the physical threat has subsided, at least enough for WikiLeaks to quietly stay away from Russia instead of actively assisting them, as they did in 2013.

The most charitable explanation for all of this is that a common enemy (for WikiLeaks and Russia) makes strange bedfellows... but that doesn't change the fact that WikiLeaks has been actively collaborating with the Kremlin

If the officer did not do anything illegal, then what right do we (as a society) have to fire them? Are they somehow supposed to be more "moral" (for some definition thereof) than the rest of the populace? Because there won't be anything but disappointment with that attitude. There's no reason to romanticize cops as somehow being better than every other person in their society.

Also, these statements are purely as applies to pending court cases, because cops sometimes do have to do things that would otherwise be illegal for anyone else. And it can take a court case to decide if one particular occasion met those necessary criteria. However, if it's deemed that a cop is not meeting some other performance criteria of their job, then that's a different matter altogether.

I think part of it is also that physicists and engineers are the ones primarily teaching the subject. So it might not be that they can't handle the mathematics, but that they simply prefer to think entirely in intuition land where they can spin functions around without anyone protesting.
