250,000 kph isn't fast enough for you? http://en.wikipedia.org/wiki/Helios_probes

DARPA and NASA are working on it. http://en.wikipedia.org/wiki/Hundred-Year_Starship

What's needed is either a faster-than-light drive or the ability to cryogenically freeze people and bring them back once the spacecraft arrives. http://en.wikipedia.org/wiki/Faster-than-light and http://en.wikipedia.org/wiki/Alcubierre_drive

If we can't bend space-time (using something like a worm-hole) or travel faster than light then there will never be any communication between the 2 civilizations.

Wouldn't it be much easier to just mine the planets we have already and build artificial planets or massive space structures out of existing planets and resources within our own solar system? Yes, the sun will eventually burn out but that's not an issue that our generation will face more than likely.

Where should we go? http://en.wikipedia.org/wiki/List_of_nearest_terrestrial_exo...

This is a very different method (FT-IR spectroscopy) than the device the original article uses (measuring electrical impedance). It is less surprising to me that FT-IR would be able to give accurate results - I would think the challenge would to be to keep costs down and be robust enough to handle the abuses of a wearable device or even a home-use device. Best of luck :)

Getting access to non-public information is, in fact, not illegal. Using non-public information from sources with a fiduciary duty to the company is illegal. You can create non-public information in arbitrarily complicated ways. For example, you could hire a satellite firm to put spy cams over every WalMart parking lot and then count the cars in them, then produce a report about WalMart's quarterly sales weeks before the market heard about it from WalMart. That report is non-public, right? Totally legit to trade off of.

Satellite analysis of WalMart parking lots is, by the way, an actual thing. (It is an actual thing which suggests, among other things, that if you are a retail investor, you should strongly question whether you really have insight into companies which professional investors do not have.)
It's problematic for a lot of manufacturers, but it's what Google, Amazon, and even MS are pushing for, since their business is software (Google through ads, MS) and commerce (Amazon). Not to mention it's the eventual result of a competitive market (Econ 101).

You could pay Bill Gates a lot of money to wear a wire for you and perhaps if the number was high enough he would do it and you could then argue that anyone could have paid Bill Gates to wear a wire and therefore everything the wire records could be public knowledge you can use to trade MSFT on. But that's illegal and we've all agreed it's illegal and its basically no different then front running in HFT.
This is a bit silly. Yes, genetic diversity is important for surviving viruses and other pathogens that come from Earth. Because we have evolved here, we can handle the other conditions of this planet. But it's not a guarantee that we'll survive the subtle changes on other planets - the gravity, magnetic fields, radiation, light, composition of the atmosphere etc etc.
I disagree that the rules stem naturally from common courtesy.

- We have a system in place that prevents duplicates.

- Except we expect you to find holes in it and bypass it when necessary.

- Except you should never delete the original before posting a duplicate.

- More?

One would think the existence of a dupe detector implied a rule against duplicates, much like a low fence still implies private property.
To be more clear when I said "most of their money" I did not mean most of their total revenue for the company, I meant most of the money they make from you during their relationship with you as their customer.

If you think about it your relationship with Apple as their customer begins with the hardware purchase, but then as you use the hardware you keep feeding money to Apple every time you make an iTunes purchase, in app purchase, buy extra iCloud storage, etc.

The goal is that this residual source of income will surpass the initial income from the sale of the hardware. In that case they could give away the hardware at a very cheap, subsidized price, or even for free and then enjoy the steady stream of money from their other services that run on the device.
Yeah, I thought "for the public to view" was very clear. I think you only wound up downvoted out of some OSS reactionism that skimmed by what you were actually saying.

I don't think this is about human rationality, or a lack thereof. It's a about whether individual rationality leads to group rationality. Whether the interest of the individual is also the interest of the group. This story is a good example: https://www.youtube.com/watch?v=sb5hr-f3Tfg#t=95

For one piece of land, yes. But if we're talking many plots, your intervention will raise the market price and other sellers will get the benefit of the higher price.
Exactly the same sentiment, making me put in extra effort to hide underlying technology seems ridiculous to me.
Apple needs to show customers what they want, that's the real issue. Since Jobs died, Apple hasn't really created a new product category that none of us knew we wanted. Instead, they've made defensive moves by making their existing products cheaper and more attractive.
"Does anyone have any recommendations"

I've been thinking about this prior to this announcement.

The way I am planning to (try to) solve this is by way of a cron script running on the host box at the location with the non static ip address.

The cron script running ever minute "gets" a page on a remote server [1] (say using curl). Actually see [2].

Another script running on the remote server monitors the apache logs and notes when the particular page is requested (along with some possibly unique and changing random number). Another script then takes that IP and updates the dns server that you have running and restarts it.

All of this should be able to be done with shell scripting and use of cron.

Thoughts? I'm not proposing this as a robust solution to everyone's issues but I think it will work.

[1] ssh to the server and gets the page locally or by VPN so that the page being requested is obscure.

[2] Of course I guess you could cut just out the apache part and also just ssh into the server, do "last" piped into "cut" then nslookup and get it that way as well.

While I'm not as fond of ggplot2 as the author is, and actually prefer base graphics when making things for publication, I think he hits on a lot of strong points.

I'm rather fond of R as a language, and hop between it and Python as my preferred tools of choice for a given task. I think the package ecosystem is it's biggest plus - for statistical work, Python might have a package to do something, R almost certainly will.

This strikes me as very boring, non-Apple style thinking. I don't think the experience of a 5 inch phone is better than a 4 inch phone. But it is a bigger number and thus easy to market. And things that are easy to market are the playground of boring companies.

Apple, on the other hand, should look at these numbers and say "people obviously want something new." Giant phones are being heavily marketed as the new thing, so people are buying them. Not because it feels good to try to shove a small book into a front pocket, or that they love having to use both hands to type out text messages.

A boring business would follow the heard because they don't know how to distinguish customer needs from customer inertia. Apple, traditionally, is very good at knowing when something is a trend, and when something speaks to a deeper human need.

I sincerely hope that Apple has not become a boring company.

Apple is periodically a boring company. It just made better macs for a decade, and slid into irrelevance. Then they got (back) a CEO that made their products relevant again. Then he died. So I'm predicting history will repeat itself.
I think I already went through this scenario around 20 years ago.

More American capitalist ways of market control.

With regular products, you buy something good. When it ceases to be good, you stop buying.

With telecom in general, you buy when it's good, and when it stops being good, it's already an entrenched oligopoly.

Game Programming Patterns / Optimization Patterns: Data Locality
I was replying to this:

*"...If that happened because HFT market markets decided not to use the TSX anymore and instead haunt exchanges that were amenable to HFT, that's evidence that HFT was helping individual investors..."

Which claims that because people move to places that are not regulated/taxed it's a proof that HFT was helping individual investors.

That was in return in the context of me asking whether the reason why the Canadian market lost out was because it did so alone.

In other words. If ALL markets included taxation would the same drop happen? Or in even other words. If something can't handle being taxed is that an argument for not taxing it? Wouldn't it just be evened out.

I am not assuming HFT is bad or good. I am actually trying to figure out what exactly it's good for.

I understand how it's good for those who trade on the market, what I have not yet seen is any examples of how that transcends to society as a whole. And until someone can give me obvious examples of that I don't believe it's irrational for me to be sceptic.

" I don't think the experience of a 5 inch phone is better than a 4 inch phone."

I would respectfully disagree with that as someone who moved from a 4.3" Xperia to a 4.7" Nexus 4 and now a 5" Nexus 5. The extra real estate is a godsend for everything I use my phone for. IMHO, 4.7-5" makes the most sense (perhaps 5.2" as well). At the very least, I think apple should give people a choice of 4" and 4.5"-4.7".

Of course, doing that will introduce a problem since most development on iOS is very focused on optimizing for a single screen experience.

> 250,000 kph isn't fast enough for you?

No. 250K kps would be more adequate. Faster == better (but we'll need good ablation shields).

> What's needed is either a faster-than-light drive or the ability to cryogenically freeze people

If you manage to get close to the speed of light, you will, from the crew's perspective, be FTL without inventing new physics. Freezing the crew is also an option, but keeping everything going for very long periods of time is challenging in itself.

> there will never be any communication between the 2 civilizations,

We still have radio. No way to phone your friends, but, still communicate, share news, share knowledge etc.
I think it's a bit like watching TV vs reading a book for a lot of people. When something is on a conveyor belt into your brain, it's easier to let it flow even if the experience is cheaper, whereas playing a game or reading a book requires a significantly extra level of 'participation'.

Of course, it could just be that I'm getting old, the dopamine hits from gaming aren't there as much anymore and that I'd rather watch skilled people at work ;-)
I worry that such an event would still be devastating. One fire was all it took to lose all of the wealth of Alexandria's knowledge several thousand years ago.
> even 100,000 might not be enough to construct advanced tech.

I think that's way too large of an estimate. As long as we could continue to access records of how we did things, and the planet had sufficient relevant resources, I bet we could bootstrap ourselves from having only primitive mechanical tools to today's tech in a few generations. Again, that's assuming the planet is relatively hospitable and has the correct resources available.
Thanks for the recommendation, I use no-ip ( http://freedns.no-ip.com/ ) did not know about FreeDNS back when I set it up when dyndns got annoying, but no-ip has been fine.
Pretty pointless since all this does is check the x-powered-by HTTP response header (which can be turned off[1]). If this captured other web frameworks as well (eg PHP also outputs to x-powered-by in it's default config) then this might be a little less pointless - but even then, most production sites should have those information leaks sealed anyway (you don't actually improve security, but at least it slows the attacker down a little as you're not spoon-feeding them information about your server build)

They've done some impressive things on the hardware front recently--the Mac Pro redesign and streamlining their MacBook line come to mind--but since the iPhone 4, which had some incredible innovations like the antenna and Retina display, their mobile line has only seen predictable iteration. I expect the iPhone 6 to be a significant deviation in form factor from the iPhone 4/5/5S because Apple is run by smart people who are rarely late to the party.
I use data.table and like it. It's fast (and I think memory efficient). plyr is IMO so slow to be unusable on just hundreds of thousands rows. dplyr, as mentioned, is the replacement that fixes it, but it was literally first released a couple months ago this year. I have no doubt Hadley will produce something brilliant, but I'm guessing it will undergo a lot of change to get there.
ERP Consultant here - of course experience is key - so to get your foot in the door, couple ways I would approach it. Your pitch ultimately needs to be, I'm THE guy for this single app, very focused and specific skill.

I would get hired at a company as a general dev or whatever and then try to transition to to a sys admin role (like "JDE Administrator"). Alot of guys work with me (me too) got in this way.

Get a year or two experience and then go be a contractor - just search for JDE contractor jobs. Or, get hired on full-time at one of the many small consulting firms that specialize in the app you're targeting.

You can come in with less experience if you can accept less salary, like at a full-time salary at a consulting co. if you can come in at 80-90k salary, that's low. I know guys got on with just minimal experience. Trust me on this, if you're smart, you'll pick up the skills.
Absolutely agreed. Gf considered going back to iphone after early annoyance with GS3, now she can't imagine it after she got used to her screen size.
Everyone in this story has the same information or rather the same access to information.

>I'm saying that if anybody can successfully predict your intentions for next year based on your observable actions to date then they have a right to the fruit of those labors

I don't see why this is so. If I have decided through some analysis that I am going to sell X shares at some date, why shouldn't that information be private? Front-running my behavior is essentially front-running my analysis. It would be unethical to hack my computer and read my analysis for yourself, so how is analyzing my behavior to get at that same information any different?
It would be the overall scope of trying to install your own system to learn it. It's a massive base product, you can certainly install it but trying to run your own test environment would be a pain without the knowledge of running a business through an ERP or the necessary test data. Typically you learn the business side of things 'on the job' and come into it with a development back ground.
SAS has missing values as well and goes further -- there are multiple types of missing values (ie, "not available", "doesn't pass quality control review", etc.) We added missing values to our product to interop with both R and SAS:

So for many distributed computations in my field (pretty much anything that isn't embarrassingly parallel [0]), the limiting factor is often network communication -- how quickly nodes can send messages to each other.

Even as just a toy, putting an affordable arm chip with a serious interconnect would be a really big deal. This is a great step closer.

It's debatable whether their descendants (or those who claim to be their descendants) can build an advanced civilization.
It is a matter of staying ahead of the curve and not let your competitors catch up. Whether that means in terms of marketing, or product quality doesn't matter. So far plenty consumers are convinced that Apple's prices are justifiable and don't have a reason to switch an ecosystem they have invested in.

You are right that Apple faces a crisis if their sales drop, so does every other company. The worst reaction though, would be to start competing on prices, and thus quality. This inevitably leads to a race to the bottom, where they're unable to compete against companies that are based in cheap labor countries. Much in the same way as Philips, or Sony couldn't compete against companies like Samsung once they lost their competitive edge in their product categories.
They don't mean charge a phone that has a lithium ion battery. They mean charge a phone that has one of their batteries, which is similar to a super-capacitor.
I actually don't know what to make of this . . . nonsense. Over here in Dublin we're trying to and are emulating San Francisco/Silicon Valley. The tech industry brings good jobs, talented people and wealth.

The tech industry is growing here in Dublin but never once have I read an article complaining of displacement of those who aren't in the tech industry. Rents are high in Dublin too! Yet this isn't the first I've heard of people complaining about wealth and jobs being brought to SF. Indeed diversity is important to all cities but I really don't think SF is lacking in diversity. It's probably one of the most diverse cities in the US if not the world.

This is like those "Americans" complaining that "Mexicans" are taking their jobs. It sounds like sore losers who were out competed.
Two of the default options on my router are DynDNS and NoIP. They both have paid plans. Is there anyone with experience with both providers who can compare the pros and cons of these services?

The problem is that the cost of a hash is several orders of magnitude more expensive on a mobile phone, than when using a specialized chip. Money, however, costs the same to everyone.

I predict that if hashcash ever becomes widely used, people will start trading hashes for money. Ie. instead of wasting 30 seconds of battery power to create a hashcash header on your mobile phone, you'd pay 1 cent to a service that does it for it. And this is exactly what Bitcoin does already.
For me it's more business-like than that: am I more productive? There's also an element of (occasional) reader feedback and the increasing size of the audience and positive reaction to the materials. These things do not measure quality with any finesse, but do at least provide a crude indication of whether the perceived quality is above or below audience-acceptable levels.
