> you are also able to get a phone that works all over the world (i.e. unlocked)

FYI: Any Verizon subsidized phones are unlocked-for-carriers-outside-the-US, if you just ask, 60 days after you bought them. As far as I know, AT&T is not as nice. I did this with my VZW 4S, which works beautifully in Europe when I travel there. So if you're a verizon customer and you don't get the "subsidized" phone, you are being an even bigger sucker than the average US mobile phone user.

Rumors are that the iPhone5 on verizon is always unlocked - don't know if that's true.

Oh, and specifically for the iphone, AT&T will unlock it for you after the contract is over, or you paid the ETF. But as far as I know, they won't do it for any other phone.

I am going to say don't listen to this guy. I think the advice is bad. See: http://www.thaivisa.com/visa-overstay-thailand.html

You can keep re-entering the country as a tourist and get an extension from what I've seen. There are a lot of places that do visa runs over the various borders. I would advise being very mindful of visa issues and respecting the laws. It's very easy to get around and get visas, but don't play around with the expiry. If you do plan to stay longer term, figure out a proper visa.
Zune does something similar to this. You put in 5 artists that you like and it tries to organize a 'picks' page with music relating to those artists. Unfortunately Smart DJ doesnt take multiple artists into the equation when generating a playlist.

I hate to say it, but hospitals need medical project managers.

My wife had some minor complications after a C-Section. We must have recited our name, address, insurance provider, drug allergies, first pet's name, etc about 250 times during the 8 day stay.

The older nurses rocked. The attending physician was someone we know well and rocked.

Everyone else, from resident down to tech were not to be trusted. An incompetent tech burned my wife's arm by putting a blood pressure cuff wet with bleach. A resident waited until I went to grab breakfast to try to pressure her into a procedure that she didn't want.
Your point number one occurred in New Zealand too. And the US is pressuring the NZ government to abandon its very successful drug purchasing agency as part of a free trade agreement. Having one agency purchase drugs for 4 million people creates a fair bit of bargaining power, which US companies do not like.

- it has directions for the link recipient. Voice directions. (ok, the voice is basic but sufficient)

- its fully HTML5-based. Works on desktop, iOS, Android.

- works without a backend server (bit.ly for URLs, map quest open directions). You can host your own easily. Infact this one is hosted on github pages.
> I asked about the cost of cancelling a 2/yr contract. They said I'd have to pay out the entire contract ($50+/month for 750mb/month). So $1200+ in any case. With who were you able to cancel and not have to pay out the full?

I'm not the parent, but I recently cancelled my iPhone 4S contract with Telstra so I could upgrade to a 5. The cancellation fee was Mobile Repayment Option (MRO) * months remaining; it worked out to about $340 with 12 months remaining for me.

This was the motivating factor for upgrading early; I sold my 4S for more than it cost to break contract.

It's actually worse than that: US government spending on healthcare per-capita actually exceeds per-capita government spending on healthcare in countries like Canada or the United Kingdom that have universal healthcare [1], let alone total spending per-capita across both the private & government sectors.

Far from universal healthcare bringing an economy "to its knees", it seems to me that the US system has a far greater chance of doing so.

Why Doesn't Apple Buy Intel?
I saw it here: https://twitter.com/asymco/status/260181615911776256

and I think it makes total sense.

Update: here's why.

Currently Apple is doing well with chips designed in-house on their mobile devices. It's not a stretch to believe that they would like the same thing to happen on Macbooks and Mac Pros.

Buying Intel obviously will benefit them in that they'll have finer control on the chip designs for these non-mobile devices than what influence they have now.

The alternative is Apple leaving Intel platform by championing some ARM architecture, which means they'll spend a lot of resources playing catch-up with Intel designs. I believe this situation not only isn't good for Apple, but also bad for the whole industry.

Just did the TwilioCon hackathon on Wednesday - the organizers set it up with two demo stands (left and right sides of the stage) and a dedicated A/V guy - while one team was demoing, they were getting the other side set up. As soon as one was done, the next team was introduced and the video was switched. AFAICT it worked perfectly.

That hackathon got through 47 demos in about an hour - 60 seconds for a 6 hour hack was actually probably the right amount of time.
Yes, that was what I was thinking, over altitude, GPS shuts off. Also I was wondering if freezing the crap out of the batteries might affect their overall charge capacity.

Reading the antics of the folks over that theregister.co.uk and their high altitude experiments (granted its mostly a lot of puns around LOHAN) what struck me was they proceed very methodically in their planning. A reasonable guide for anyone wanted to get into the space balloon business I think.

I don't know, but it's not meant for hosting pages or page resources unless you use their "pages" feature, so they set it pretty low.

We know different bachelors. Most of the non-fratboy pads I have seen that are truly depressing are an inflatable mattress/pile of yogamats/camping mattress on the floor and a pile of books (sometimes a laptop). I've been in 4 bedroom houses which other than a thin layer of dust had nothing but the mentioned items in them. Some view their lifestyle as minimalist, others just don't see the need for owning anything. 'I don't need a fridge because I don't cook', 'the washing lady comes once a week, so I don't need a washing machine', 'I've never opened that cupboard'. Those sort of statements are signs that you need to help your friends get some serious help. If someone can't come round to your house because of your 'minimalist' lifestyle that is a serious problem. Humans are social creatures, if you can't socialise something is wrong.

That sort of lifestyle is just as damaged as the sort that compels people to store every pizza box and newspaper in the corner and prevents them from throwing anything away.

The GPS receiver doesn't shutoff. The requirement is to stop tracking.
The fact that something might work in "numerous other countries" is of limited utility in determining whether it would work in the US.

Consider: If your kid is a bad student, pointing out that the neighbor's kids down the street are excellent students doesn't really help your kid pass math. Telling Microsoft or GM it should just "be more like Apple" doesn't mean they could succeed following Apple's strategies.

The US system has been very different from these other counties for quite a long time. We have different values, different skills, a different history, a different political process. It's quite possible that you simply can't get there from here. The transplant surgery necessary to put a european welfare system into an otherwise-American sociopolitical system could kill the patient. America is just NOT LIKE a tiny european country, and the ways IN WHICH they are different are relevant to what is politically and practically possible.
Or, rather, this is about compressing random sets == compressing random arrays with w/o being order precise.

Is the number of all possible distinct sets of 1 million 1..10^8 numbers less or equal to 2^(8 * 1024 * 1024)?

And if yes, is there a way to transform the buffer from one intermediate state (representing the "not yet fully" received stream) into another utilizing a small amount of registers?
so how was that doing now?
I can do it in about 3-4 clicks. I have never been in a situation where I could not afford 20 seconds to look at my phone, at a light or some such at the worst. I could make a Taskr shortcut or an on{x} shortcut, but that's probably not what you meant.

Isn't the assumption that universal health care will have no rules just as based in speculation as the idea that it will?

'Universal health care' is a pretty broad term. Most discussions that aren't about particular implementations are meaningless.
It was just a question of when.

Curious to see how much pushback there is, or if 'Sponsored' posts are stigmatized or accepted.
Here's the solution that I came up with prior to following the link or reading any comments.

We're given 1 million integers from 0 to 99,999,999. We only have 1MB of RAM, or an average ~8 bits for each of the million numbers. So we can't store the numbers directly since they take ~27 bits each.

First thought was to use a bitset but that would require 100 million bits, and we only have ~8 million bits RAM, so that's not going to work. Also need to deal with duplicates.

How about this. Something similar to a selection sort algorithm that stores deltas of distances between sorted numbers. As a number is streamed in, we start scanning from the beginning of the list until it's correct position found, where it is inserted and then push down the remaining numbers. This will be O(n^2).

Since the average delta distance between numbers is about 100, we'll use 8-bits to store the delta value. Value 0 means the number is a duplicate of the current number. Values 1-254 mean add this number to the current number for the new number. Value 255 means add 255, then use the next byte as the delta value (repeat until the value != 255).

(Case 1)
1 million ints exactly 100 apart:
0, 100, 200, 300, 400, ..., 99999800, 99999900
Stored as a list of 8-bit delta values:
0, 100, 100, 100, 100, ..., 100, 100 (1 million bytes total)

(Case 2)
1/2 million zeros, then 1/2 million values of 99999999.
Stored as:
start: 0, 0, 0, 0, ... (1/2 million zero deltas)
then: 255, 255, 255, 255, ... (99999999 / 255 = 392,156 times repeated, which gets us to number 99,999,780)
then: 219, 0, 0, 0, 0, ... (another 1/2 million zero deltas)

So the total amount of storage for Case 2, which I presume is worse case (but correct me if I'm wrong!) is:
500,000 + 392,156 + 1 + 500,000 = 1,392,157 bytes to store the delta values.

1MB = 1,048,576 bytes, so I'm over by 343,581 bytes... (so close!)

We'll have to modify this scheme so that we reduce the number of 255 values, which should not be hard to do and will get us under the 1MB size limit. Or we could try something fancier like huffman coding to reduce the size of the delta values.

For me, it was the digitizing phase. Tearing apart a yearbook, page by page, and feeding it through a scanner? Taking a picture of something you got as a gift and donating the actual thing?

Sometimes an item exists just to be itself. A yearbook doesn't have any value if it isn't yours, or if you don't invest it with some. If you decide you don't want something, fine – but it seems very strange to keep around a formless simulacra of it.
Well then- no harm no foul. Guess I took the post too seriously..

If you're near an airport, it's still probably a good idea to notify the FAA that you'll be doing a launch.
I would have thought 5000fps would produce slower footage.
Its truly amazing to see how far few hundred bucks can get you this days, but can we please stop calling these stratosphere launches 'sending to space'? Is it just me or 'sending balloon to space' sounds like joke?

Seems launching another one(or even few) could be cheaper than searching for this one...
this is not a comment on being a parent, working on a start up, or the difficulty of either or both. It is about how poor word choice was used to make an enticing title, hearing 'living a double life' i think that most people see that as two separate or two lives secret from one another. Is this just me? I googled it and as I skimmed the top stories it was all about secret lives.

> Any hard empirical evidence for this assertion?

There's no hard empirical evidence that Scientology is crap, but I'm comfortable making that statement too.

Statistical studies showing little to no positive correlation between level of training (not including practicums - which the UK is obviously using extensively, good on them) and student outcomes is pretty damning though. There's some correlation between doing a masters level education course, and English teaching ability, but OLS shows this is just because students with good English ability (high writing scores in high school) are more likely to do a masters level teaching course.

> Yes, teaching and learning is not a field that depends on hard facts alone. The 'soft' factors are important as well. Student teachers need some pointers, models, methods, examples of how to deal with the soft factors.

For example, they should be learning psychology that's not so outdated that the Cosmopolitan magazine should be embarrassed to write articles on it (Myers-Briggs is totally discredited). I'm not saying I'm a hard reductionist. Education should be based on fundamental psychological foundations if possible, and while that's not always possible they should at least try to either teach stuff which is fundamentally sound, or actually works in the classroom.
Further to point 2, it always costs more to call a cell phone. In the US the recipient essentially pays the extra over a landline and gets a bulk discount for doing so. In most other countries the caller pays more for making the call to a cell phone. The price difference can be staggering.

Look at this (random) calling card rates page where it gives the price per minute to call from the US to various countries: http://callingcards.com/shopping/qj-phone-card-usa.asp

Note how much more it usually costs to call cell phones versus land lines, sometimes ten times as much. Don't forget the rate includes the transit of the call from the US to the country as well so the actual difference can be even greater.

It does seem somewhat fairer that the person making the call is hit with the extra charges, but at the same time it is far harder for them to get a bulk discount since the charges come from the recipient's network.

All that said the SMS situation is because the US carriers could get away with it.
haha yep, i thought of this like 6-8 years ago. from what I've sorta thought of in conjunction with your statements, I'd like to add that there's numerous processing and hacking issues and whatever else. It's extremely insecure. The closest we will get to this is the "cloud".

It seems like a good iterative approach to me. Classic desktop apps can still run, but it seems clear they are no longer preferred. WinRT offers an interface over Win32, a skim coat to even out all the cracks, quirks and special cases that have appeared over the years. At some point down the line you can jettison Win32 altogether and replace it with whatever you want, or even leave it in place.

I meant the connector. Point is that electric cars are pretty much just hitting the market and it would be really silly not to internationally agree on a plug for the thing. Since it takes DC power in anyway, you need to convert it from whatever arbitrary voltage AC power your given country has.
I agree this will be studied like the Osborne Executive gets studied in business schools. I've seen these sorts of transitions managed in different ways, they all have their risks. Commodore-64 to Commodore Amiga (unsuccessful), Apple II to Macintosh (successful), Emulex Storage to Networking (not successful), IBM Mainframes to software consulting (successful). It is a tricky tricky thing to do, to take your company's most profitable product and build a replacement inside its market internally.
> I wonder how much time that would take to crack on modern hardware...

A very long time. You're still looking at a total of 3-5 words you need to guess (9-25 characters based on 3-5 letters per word), in the right combination, and assuming all words are English or popular colloquialisms...

("greatly reducing" is still not going to make brute forcing a realistic choice).
> "git branch --set-upstream" is deprecated and may be removed in a relatively distant future. "git branch [-u|--set-upstream-to]" has been introduced with a saner order of arguments.

It would be great if changes to the git CLI were thoroughly thought through instead of one-off fixes like this. This is the reason the interface is such a mess.

git branch foo --track origin/foo

But if you forgot --track:

git branch foo

then it's:

git branch foo --set-upstream-to origin/foo

and don't you dare do

git branch --set-upstream-to origin/foo

Upstream and track are the same - why two different words?

And now we have --set-upstream-to and --set-upstream, which will be fun for git newbies to distinguish.
He just added not infront of all your logical arguments.
