They aren't.

Most of them are open from other tasks. But that doesn't make them a distraction. They're there for when the current task finishes and I can go back to them.

The alternative is to close them all down and reopen them, which is vastly more time consuming.
There is more information on Michael Minovitch's website:

http://www.gravityassist.com/

He sounds rather bitter that his story has not made him more famous, and comes off as something of a crank at that ("How Did Minovitch Discover (Create) His New Theory Of Space Travel?"). I think Minovitch is basically an engineer at heart, and is resentful that all of the attention seems to go to the scientists, i.e. people who come up with the actual physical theories about mass and energy and so forth.

Our culture does value scientists more than engineers. You could argue that this is good because theories are universally applicable and represent fundamental understanding, or that this is bad because many theories have absolutely no applications and that it's the engineers who deliver value to society. You could also argue that the amount of prestige that we heap on scientists tends to go to their heads and they stop doing good work. But whatever. Stay sharp, do what you're best at, and don't pay attention to other people's benefits packages.
Thanks. Go is definitely interesting but my biggest concern with it is, it is so new that it might take few years for the adoption.
It's very common to use gravity assist, especially in outer planets missions. Fuel is very expensive and has diminishing returns (the more fuel you put on, the more fuel you need to lift the extra fuel you put on). After Voyager, Galileo, Cassini, and New Horizons (among others) have used gravity assist to get to Jupiter, Saturn, and Pluto respectively (NH is still en route).

Even Stereo, a two-satellite pair in earth-trailing and earth-following orbits looking at the Sun, used gravity assist (with the Moon).

Gravity assist is one way to provide "delta-v" (velocity change, the coin of the realm in propulsion). You can provide negative delta-v using aerobraking -- orbiting your destination, Mars say, and slowing down using atmospheric friction. This is used on the Mars orbiters.

As usual, see: http://en.wikipedia.org/wiki/Delta-v_budget

I watched the Dawn spacecraft[1] launch, it uses an ion propulsion drive which Wikipedia says can perform a velocity change of over 10 km/s over the mission.

My understanding is that if they left the ion drive on long enough, the craft would continue to accelerate.

Totally agree with matthewowen's comment above. Also, as a woman in tech, I hear all the time that "women just aren't as interested in computer science as men are," yet in my experience that's not at all the case. In India (where CS is not seen as something that predominantly boys do) 55% of CS degrees go to women. In the 1960s people said, "women just aren't as good at playing instruments as men because they don't have the lung power;" when blind auditions were introduced the number of women accepted into major orchestras tripled overnight. There are a lot of examples of people assuming women "just aren't interested" and that changing very rapidly when cultural barriers and discrimination is removed.

Same here - I'll never recommend them, and have actively discouraged people from using or investigating them.

They may be great technically, but I always mention their spotty/inconsistent and poor treatment of me as a customer. Even if I'm not the most lucrative customer, how you treat every customer is important. You never know who, dispute being a low-revenue personal user, is a high-revenue business user.

Christoph Janz, by the way, was an angel investor in our company CalendarHub (an early YC applicant who lost out to Justin Kan's Kiko, I believe). We were lucky to land him, but we weren't at all prepared to take advantage of Christoph's deep knowledge and insight (neither of us were willing to take the leap to full-time), else we might have been far more successful than we were.

Christoph was boots-on-the-ground the whole time. Hell, I would say he was in the trenches with us, but that is giving us too much credit. I think he was practically the only one in the fire-fight at times. He was tenacious and bold and he operated on a completely different level than us. At the very least, I got my first glimpse of what a real driven tech entrepreneur looked like.

Rackspace Cloud's offering is nice, though, in that you get guaranteed, durable storage with each instance. Their EBS-like offering will allow people to supplement that storage if what they have in-machine isn't sufficient, but users will be able to decide for themselves about the speed and reliability tradeoffs around what goes where (unlike with Amazon, where everything that needs to be durable has to go on EBS). The resulting system will be both more flexible, and, I would guess, more performant, if only because I would expect lighter load given that many users won't need to use this offering at all.

Separately, it also seems that Amazon's architecture under EBS has at least some per-AZ single points of failure, such that certain classes of issues can take down storage for a whole (or at least large parts of an) AZ. There doesn't seem to be any a priori reason that this needs to be the case; I could imagine an EBS-like system that would have storage per rack, say, which would appear similar from the user's perspective except that it might perform better and would be unlikely to disable all of their instances at once if it failed. No idea how Rackspace's implementation works, but I doubt all EBS-like solutions are created equal in terms of reliability.
On facing two years for protesting Stop-and-Frisk
Sounds vaguely like walmart's anti-union emergency lawyer team:

Wal-Mart has responded to the union drive by trying to stop workers from organizing -- sometimes in violation of federal labor law. In 10 separate cases, the National Labor Relations Board has ruled that Wal-Mart repeatedly broke the law by interrogating workers, confiscating union literature, and firing union supporters. At the first sign of organizing in a store, Wal-Mart dispatches a team of union busters from its headquarters in Bentonville, Arkansas...

...The retaliation can be extreme. In February 2000, the meat-cutting department at a Wal-Mart in Jacksonville, Texas, voted to join the UFCW -- the only Wal-Mart in the nation where workers successfully organized a union. Two weeks after the vote, the company announced it was eliminating its meat-cutting departments in all of its stores nationwide. It also fired four workers who voted for the union. "They held a meeting and said there was nothing we could do," recalls Dotty Jones, a former meat cutter in Jacksonville. "No matter which way the election went, they would hold it up in court until we were old and gray."

>Still, I wouldn't for one second claim that I, or anyone else, could do better than AWS on reliability. //

That may be true over all customers but for reddit I'm estimating about 1 day of downtime for me in a year (that might even be conservative?) - so that's 99.7% approx.

Joyent are claiming that their customers [who?] have only about 30s of downtime per annum.

Reliability obviously extends beyond downtime but still AWS don't seem to be do incredibly well for reddit.
Your implication is that Facebook themselves sold this data. The orignial article says that it was from apps that people isntalled from a 3rd party, not Facebook.
What exactly are the 10 instances? Did you add VPS's or just more child processes to handle connections?

If you haven't already, it's good practice to calculate how much resources one instance/thread/process of your server takes up, and then allocate as much as your server allows. (of course take into consideration shared memory/copy-on-write when calculating limits)

No one will believe its related and its certainly not slander to joke about it. Also you might want to leave the political opinions out of hacker news... there is no 50% of US who dislikes those things, they only have different ideas about how to support it.
That's not necessarily true. Adding Network latency on top of Disk latency is clearly a net loss. However, network latency and disk seek latency stack in a different fashion and most servers don't really hit there disk all that hard. Which opens arbitration opportunities between those who need R/W and disk space.
I will use it for my drawing learning. Thanks.
Some people complain about bloat and bad compositing performance under X, but my real problem with X is that it's very insecure.

That's quite neat - would be useful to those of us looking for property in London.

But, and I'm sure you've heard this from other people, the biggest problem with finding properties in this town is that basically every single property shown on any website has already been rented.

> That being said, I think it would be nice if Google made this particular functionality optional. For some shared user environments where you want to maintain the illusion of privacy (e.g. "family computer"), it might be nice to force password to view more sensitive information (e.g. e-mail).

Agreed. No difference for me since I have my Google powered mail all going into Mail.app which does not require a password, but in some shared environments I definitely see the point. Though in a shared environment you should be using different accounts otherwise stuff like Google Drive and Dropbox don't really make sense anyway.

"b), okay point taken. So, don't work at IBM, if you can help it."

You can't really help it because there is no guarantee that IBM won't just come along and buy the company you work for. I know lots of people that quit my company when IBM bought it. For this one older lady (HR Director) she has had to keep getting new jobs because 2 of the last companies she worked for got bought by IBM. She doesn't want to work for them so she just had to find another job and then quit.

Hey guys, OpenRent [1] founder here.

Firstly, site looks great and seems to function well. We built a similar commute time search last year, our interface could definitely do with some work - but it's a feature I think is awesome and people use.

However, in my opinion, the real problem with property searching of the past 5 years has been data. The data quality is poor as letting agents aren't incentivised to keep it honest, and keep it current. After all, they want tenant leads of any sort.

And that's just the search side. When you start looking into how else you can save money and improve the system for tenants and landlords you'll realise you're only scratching the surface.

Hence, whilst it's an awesome tool, I think the whole sector needs to be improved first. Maybe you can limit your search to OpenRent listings, and then you'll be keeping tenants happy! ;-)

But seriously, good luck with it - and if you wanted to chat, you can catch me anytime via the email in my profile.

I find the lack of transparency on Amazon's part entirely unacceptable.

(I can imagine and understand -- although not always agree with -- the desire to e.g. keep some technical aspects of fraud detection private. Beyond that, I have zero sympathy.

And even in the event of some so-called "fraud detection", we have powerful entities who on the one hand want to benefit from a "global market" while on the other hand simultaneously seeking to restrict same when doing so is to their benefit. For example, taking advantage of lower "third world" production costs while insisting upon receiving "first world" prices for their own goods.)

P.S. I've had two friends communicate that they are backing out of pending Kindle purchases, since I shared this story with them. (In case any Amazon types are browsing by here.)

Thanks for that link. Minovitch seems to still live in LA.

He also mentions his solution as addressing the three-body problem, so maybe that's where the writer of the linked article got misled on that point. Too bad the writer of TFA didn't check this out with an independent expert.

Don't tell the spammers making millions of dollars about that header trick.

Seriously though, I don't think a couple of headers will cause an email to become not spam. Google's filter is probably Bayesian, and considers the content of the message, the matching between the originating server and the reply-to address, the spam history of the originating server, any links in the message, how many times it sees the exact same message, how many people mark it as spam, etc.

So maybe it will get through to the first few hundred people, and then they'll block it.

I got burned several years ago, when a $150 textbook was stolen during delivery. It was sent via FedEx, and someone somewhere along the pipeline had 'signed' for it by writing my name in all upper-case letters.

I went through a lengthy process of submitting paperwork, at the end of which I was told that since the book had been signed for in my name, I must have received it and therefore I would not be compensated (so why did I have to spend time and money jumping through hoops?).

No doubt I should have pursued this further, but at that point I let it go. I just cancelled my account and haven't purchased anything from them since.

I guess its a tough situation when a customer claims they didn't receive an item, but I was a regular customer who spend hundreds of dollars per year with them, so they could've given me the benefit of the doubt at least once.
To me it sounds just like he framed what happened in the IT industry in most corporations from 2001 onwards in a 'IBM is evil' manner. Dotcom happened, bombed, local skills got paid less while jobs got shipped offshore or automated away. The post about H1-B visas that he mentions, appears to be what most large corporations do with L1 visas, and that's probably what IBM was doing too.
No, you outsource the work, not the responsibility.
It's expensive to install infrastructure, but the costs aren't as high as these companies would have you believe, and further, they've been receiving money for years that was specifically intended to deliver fiber to the home.

There's already so much capacity sunk into the ground you wouldn't need to dig for another decade, you could just upgrade equipment on the end-points. Expensive but a lot less work than getting permits and ripping up roads.

If the rumors about Google are correct, they may be in for a rude awakening.

Fair enough, I stand corrected. The problem is in the culture surrounding cloud services, not with the providers themselves.

So it seems that the only real benefit to utilising cloud services is to make scaling up easier and save money.
If you are interested in gaining a more intuitive understanding of the forces in play (and have some time to kill), I recommend grabbing a copy of Kerbal Space Program. Its only in alpha right now, but its a heck of a lot of fun already and does a really good job of teaching you how to use orbital mechanics to land on other planets (or to shoot a probe out of the solar system, if you want to try to do that).

Their model is definitely simplified (no lagrange points, for example), but the major aspects are modeled well enough to give you an idea of how interplanetary space travel works.

Yesterday, for the second time in two years Techblog was offline most of the day due to an Amazon AWS service outage. That’s effectively, for business purposes, 364/365 = 99.726% uptime.
