I think the GP was asking if there are always less than 600 between primes. The answer to his question is "no". The higher you go the larger gaps can be between primes. There can be untold millions/billions/trillions etc. between two distinct primes. This proof shows not that there are never more than 600 between primes, but that there are an infinite number of pairs of primes that are separated by less than 600. The difference is small but important. There may be two primes separated by a vast number, yet the higher you go there will always be a pair of primes coming up that are separated by less than 600.
2^57,885,161 - 1
2^43,112,609 - 1
are primes. They have 17,425,170 and 12,978,189 digits in them. They are the largest two primes we know of. They are separated by a bunch of numbers in between them, almost 5,000,000 DIGITS (note digits not numbers) and all the numbers between them are composites. HOWEVER, the next largest prime may simply be (2^57,885,161 1) + 600 because there will always be a chance that there is a prime coming up less than 600 away from the current highest prime.
This is getting closer and closer to proving the long held belief/hope that there are an infinite number of primes separated by only 2. NOT that EVERY prime is separated by 2 from every other prime. That would be obviously false. Simply that there are an infinite number of primes salted throughout all those impossibly high ones that are only 2 apart.
Upon arriving in the USA very recently my wife was flagged going through the mettle detector at IAD (she was carrying our 3 month old daughter so the TSA told her they had to do some extra checks since she had a baby in a sling, dafuq?). She spent the next 45 minutes getting checked, rechecked, patted down (enhanced pat down; under the waistband, hand up the legs until it meets "resistance", hands swiping breasts, etc.), having her carry-on bags checked and rechecked for bomb residue, all in the name of "You were carrying a baby in a sling".
I'm trying to be as honest and non-paranoid as possible in all of this. But these leaks from Snowden really do give rise to questions about how large my NSA profile has grown, simply because I live overseas.
Oh... Mozambique is the 3rd least developed country IN THE WORLD according to the UNDP
So yeah, this Les Cotrell is just a guy wanting to sound smart by explaining things about Africa to people who know nothing about Africa. This happened long ago.
Affordable by those who need it
I would love to see this vaccine become a reality but I'm not very hopeful that this would have a price tag that many African nations could afford to give out to their populations for free or, if not free, the pennies the average citizen could afford. Mozambique, where I live and work, is VERY hard hit by Malaria but it's rural areas are very poor and the medicine distribution points in the CITIES struggle to keep vaccines refrigerated and properly handled. There is much development to be done in many of the nations who see high death rates from Malaria before we can use phrases like "allow us to do away with this disease". I do hope to see the disease done away with but let's not assume that with the development of the vaccine that that victory is imminent.
You don't know how right you are. This is REMARKABLY stupid and dangerous. The countries in Sub-Saharan Africa are developing and with development comes all the growing pains, not least of which is very very corrupt police. Police in South Africa and elsewhere on this continent can be very vindictive and outright murderous when upset about people disrespecting their authority. A few months ago a teenager from Mozambique was dragged to death behind a South African police car because the police who "randomly" stopped him felt disrespected. If the people on these lists know about this hack and their names being made public there is a very real and justified fear they now permanently live in. If they don't know about this hack (a bit more likely in a developing country with a not-so-exposed-to-the-internet underclass) they may be blissfully unaware of the danger they are in but that does not change the its depth.
Whoever released this info has very real blood on their hands. I don't give a damn about the title "Anonymous", the script kiddies who released this info are accessories to the horrible vindictive violence that will assuredly come, and the potential of the loss of life for many of the names released.
The stupidity of this move cannot be overstated. Be ashamed of yourselves "Anonymous". Be ashamed for your lack of disciplining your own.
The Jolla hardware looks similar to that of Nokia’s Lumia, with a clean, button-less front face that houses the 4.5-inch touchcscreen.The phone will use a dual-core processor and support 4G LTE in some regions. Internal storage tops out at 16 GB, but can be expanded via microSD card. The phone also includes an 8 megapixel rear camera with auto focus.
The phone is also “Android app compliant” which, in a move similar to that of BlackBerry, can help with available apps at launch."

The shuttered file-sharing site Megaupload has accused the United States government of trying to change criminal court procedures to make it easier to prosecute the firm for copyright infringement. In addition to naming CEO Kim Dotcom as a defendant in the criminal case, the US government also named Megaupload, a corporation based in Hong Kong, as a separate defendant.
Megaupload has argued that US law doesn't allow criminal prosecution of corporations based entirely overseas. Federal rules require notice of an indictment to be sent to a corporation's last known US address. But Megaupload has never had a US address, the firm argues, so it can't be prosecuted.
Judge Liam O'Grady rejected that argument in October, reasoning that the government may be able to satisfy the notice requirement by serving papers on Kim Dotcom after he has been extradited to the United States.
On Thursday, Megaupload pressed its case again by pointing to a letter that Assistant Attorney General Lanny Breuer wrote to the chair of the Advisory Committee on the Criminal Rules, which is part of the judicial branch. The government's attempts to change the criminal rules are an implicit admission that Megaupload is actually correct on the law, the company argues."

Thanks. This is the kind of situation I'm in, and your suggestions seem like good one's. I'll look into those.
Holy hell, that's a lot of assumptions about me! It's really not offensive and it kinda makes me laugh and I guess my submission doesn't really describe my entire situation so I can't really blame you. I would probably tend to agree with you about most cases of people who live overseas, especially doing NGO work.
An honest, "Thank you" for caring about my marriage and family.
I may be flattering myself but I really think my marriage is awesome. My wife and I love each other immensely and we support each other quite a bit in the work we do.
My basic situation is this: Work situation aside, we have our kids in bed by about 7:30 or 8 each night and after that we have very few entertainment options. We don't do this every single night but we often find ourselves watching a movie or TV show on DVD together. This works well and I have no complaints, it's just that our DVD collection has been watched enough that we are both looking for new entertainment options when we want to wind down together in the evenings. I'm just looking for ideas for how to spend 4-8 hours per week with my wife and engage her in what I find to be a rewarding and entertaining pastime; computer gaming. I have almost completely stopped computer gaming after getting married and it wasn't a hard decision to make. I gladly left those games behind when we got married and I don't begrudge the sacrifice at all. I'm not addicted to anything, she's not looking for more attention from me, I just want to do something new with her and I thought the Slashdot community might be a resource for finding out.
Yes, it is very weird. I don't really hang out with other expats who have that mentality. I live here and I'm happy to be here. It's my home, my kids were born here, they are citizens of this country and I don't want to create an American bubble around myself and my family. I'm actually a missionary and, let me assure you, I spend a LOT of time with the culture I'm in. I'm not trying to avoid spending time with Mozambicans. I'm trying to find an interactive activity I can do with my wife in the evenings after our kids go down. We don't have many board games, we can't go out (they kids are asleep in the house) and we are often sitting around without many options for evening entertainment except movies or TV shows on DVD. I want to invite her to join something I really enjoy doing (computer gaming) and find a lot of value in. It's nothing to do with avoiding local culture or neglecting my kids (as other posters have assumed).
