Yes, yes, yes! Having the "late" commit (session 1) fail in this case is exactly what I would expect as "correct" behavior.

It is the Indian mindset to solve every problem by hiring more people. Thanks to the shitload of cheap, unskilled engineers, this dream is economical. A friend had contracted one such company to overhaul his website. He has been co-ordinating with 4 - 5 people in the company, and it's been over a month, and these people can't write a simple 301 redirection without breaking his whole site. My friend happens to be a non-technical guy, so he can't see their shit. Sad.
Python is strongly typed, you mean statically typed.
No, they didn't. The number of medical bankruptcies is:

# Medical bankruptcies = # bankruptcies x [P(bankruptcy | medical event) - P(bankruptcy | no medical event)] x P(medical event)

The study in question merely measured P(medical event | bankruptcy), which is what that 62% number represents.

The verbiage of the study and press release confused a bunch of innumerate reporters, but HN is smarter than that.

Speaking of form factors, I'm really looking forward for a widely-accepted form factor for living room electronics. Rarely any devices still require 440mm of width, and thus all consoles, set top boxes, sat receivers, small HTPCs and many stereo amps invent their own. Along with a huge rat's nest of cabling, this just looks immature.

I'm actually excited for stereo amps, or other home entertainment gadgets, in raspberry pi format.
> Except that drugs are such a culturally charged issue that "argue" and "assert" become the same thing.

No, the fact that some people are emotionally invested in an issue doesn't mean that "argue" and "assert" become the same thing, its just means that "assert" becomes a lot more common than arguing.

What culture?

The arguments in favor of what?
This is not true, or is only partly true depending on which KKK you are talking about. The original group formed in the 1960s as an anti-reconstruction organization and used terror tactics to chase politicians and businessmen they didn't like out of certain communities in the South. It didn't last long though and was disbanded in the early 1870's.

The 'second' Klan was originally a merchandizing effort surrounding the movie "Birth of a Nation." It quickly turned into an actual political organization which adopted the white nativist views which were in vogue at the time. It was largely anti-immigrant focusing on Catholics, but also targeting Jews and Eastern Europeans.

It's worth noting that in all of it's incarnations, the Klan was racist and anti-black. It wasn't until the 1960s that this became the center-point of their politics, but it was always there.
Ah, my point wasn't that I want to be online a lot. My point was that I want to get online and get my work done. That way I can log off sooner and go do other stuff I enjoy doing.
Of course Yasser Arafat was killed. I don't think anyone sane ever thought otherwise considering the circumstances... Same goes for Slobodan Milosevic... There likely are others, but they don't come to mind at the moment.

Love the anonymous downvote for saying something unpopular politically, but more than likely factually correct.

Dangerous political prisoners/personalities dying in mysterious circumstances at opportune times is not coincidence. The US reign death from above via remote controlled drones and this isn't contested, yet thinking that very suspicious deaths at expedient times are likely assassinations is some crazy conspiracy theory...

Double billing for travel & work done during travel is definitely ethically verboten, and frequently specifically used by lawyers as an example of unethical behavior.
Yes, of course. A full fledged sysadmin is expensive, and startups will typically make several costly mistakes before going to that expense.

This is not surprising, and is not even regrettable. If the business can't support the overhead of someone who doesn't directly bring in revenue, then it can't. And if there's a large investment that makes good infrastructure engineering possible, first-time entrepreneurs might not realize that they need that function.

The key to long term success is in realizing what you will need before it's too late to get it.

> considering that the sellers might be cops

Why wouldn't law enforcement pose as buyers, as well? This is a common tactic in narcotics enforcement. Entrapment often isn't an issue, as the seller took the first step of advertising the drugs for sale.

Are you getting at the fact that the buyer must have a receiving address, while the seller can ship anonymously? I would be skeptical of that. If I were attempting to track the source of a package, and I had the full force of warrants behind me, I bet I could track down most shippers.

Every shipping company has its own tracking information. Much of this may be opaque to the end user. The tracking might be much more detailed than what you can see as an end user with a tracking number. Assuming the carrier cooperates with law enforcement, tracking could (presumably) be further enhanced for targeted post offices, routes, etc..

For example, suppose I, as a law enforcement agent, receive an order from a Silk Road seller. Let's say it was shipped in an envelope, dropped off at a USPS street-corner box. From the tracking info, I identify which post office first handled the envelope. Thus I narrow my search to a few possible mailboxes served by that post office.

I instruct the carriers at that post office to assist me. As they follow their routes, emptying mailboxes, I have them sort outgoing mail into separate bags, one per box. I have the post office flag any mail going to my address.

I place another order from the same seller. When it hits the post office, it gets flagged, and because of the per-box sorting, I know which mailbox was used.

For round three, I place yet another order, this time with the mailbox under surveillance. I also install a camera inside the mailbox that sees the destination address of every envelope deposited. When the seller drops his shipment, my surveillance team detects it. They then follow the person who dropped the letter. Now I have the shipper's identity.

Can these measures be defeated with appropriate opsec? Maybe, if you know exactly what tactics law enforcement will employ. But you don't. You could spend all your time defending against the tactics I just described, only to get caught because law enforcement came up with a totally different strategy.

My point is, opsec is really, really hard.
Yeah, I mentioned it in comment under the post.

Here's a quick review from the Guardian to get you a taste: http://www.youtube.com/watch?v=ryCfjX7DRqM
It's wrong to portray this as a trade-off between more risk or less risk. In reality it's a trade-off between two kinds of risk. Without the NSA snooping there is a higher risk of terrorist attacks, but with the NSA snooping there is more risk of attacks on democracy. Imagine j. edgar hoover or richard nixon able to use all that NSA data for illegitimate purposes. How easy would it have been to supress dissenting political opinion? The NSA database is a time bomb of political abuse just waiting to explode. Its very existence is a threat to democracy.

Show HN:  How much can you tell about someone from their tweets?
Can an existing company be pitched as founder for startup?
So we are building up a startup. We have a bit mixed up founder configuration:

- We are three partners who are already running a profitable software services business for over 6 years. We all get along very well.
- I will be moving away from the services business to setup and get this new venture running in a new partnership with a new co-founder (my brother).
- My other two partners will also provide all the required support to this startup and will also continue to run our existing business.
- our new co-founder is not quitting his full-time job immediately.
- all four will hold equity in the new venture (not equal)

An honest picture of our setup would be:
1 founder - self - tech and UI - 100% time commitment
1 founder - existing partner - project management/marketing - 50% time commitment
1 founder - existing partner - sales - 25% time commitment
1 founder - new cofounder - tech - 50% time commitment initially

Any advise on what would be the best way to present this founders setup as we approach incubators/angel investors (got rejected for YC w2014 btw). Is such a founder setup likely to be rejected by investors?
The existing business will provide a lot of support for this venture, it works in equity distribution terms so can our existing company be pitched as a founder?

I think personal data is a very interesting subject and is more beneficial to see what you are doing and how you can better improve yourself.

I fasted for about 28 days once, when I was 18yo. Just water. Coming off it took days, with just diluted orange and apple juice. Eventually after about a week I started on solids. Quite an experience. I was perfectly healthy before it, and completely refreshed afterwards.
Something always troubled me: Why are long hours the equilibrium? If everyone is fighting to hire engineers, why not proudly declare "We're working 40 hours a week here, and still pay market rates"? Every engineer in town would consider working for you. Or not?
Any particular reason you're assuming this one is terribly programmed and horribly insecure? Other than past experience, I guess.
Apple increasingly proves that intransigence in response to customer feedback is not a defining feature of Apple's aesthetic. Another example is the reduced motion setting in iOS7. There's no need to piss people off just for the sake of purity; Steve gave that to Apple, but it is fundamentally distinct from Steve's primary gift - his vision of consumer products. Steve would have berated you for using Applescript, until Apple released the update a year later that supported Applescript.

I completely agree with this. Looking at it from a civil disobedience standpoint really exemplifies what we need to do to protect our freedom on the web in the coming future. With the onslaught of information with PRISM, spying, etc. the general public becoming aware of these sort of "rogue web pirates" is quite important to raising awareness even if it is only due to shock value that the general media is reporting it.
Lots of advice exists for startups. Not so much for creative endeavors.
OK, since you asked:

> The sound wave produced by a piano note is a simple sine wave.

No, it's not. A piano note is a complicated stack of overtones (some of which are harmonic and some of which aren't) and transients. If it was just a sine wave, it would sound like a sine wave and not like a piano.

This is part of why things like Shazam are so difficult: musical notes aren't just a single frequency in the FFT, they are a stack of them.

> You could just tell them a handful of numbers—the sizes of the different circles in the picture above.

This is actually the exact same number of numbers as in the time-domain series. Taking the FFT on its own doesn't reduce the amount of data, it's about discarding or compressing some of the frequencies after you do.

> The really high notes aren’t so important (our ears can barely hear them), so MP3s throw them out, resulting in added data compression.

This is only part of what MP3's do, and at high bitrates this really is inaudible. The main source of compression is that the precision of the numbers used to represent the amplitude of the sine waves is reduced.

When you have a loud sound and a quiet sound at the same time, the loud sound will "drown out" the quiet one (called "auditory masking"). You won't be able to hear the quiet one, or one be able to hear it precisely. MP3 and other audio codecs take advantage of that by encoding quieter frequencies with less fidelity when there are other louder frequencies at the same time. You don't notice the loss of precision since it's buried under louder sounds.

> Just as MP3s throw out the really high notes, JPEGs throw out the really tiny circles.

This is off too. If JPEG discarded high-frequency signals, you would just be blurring the entire image. It would be exactly like saving it scaled down and then scaling it back up with some smooth interpolation.

Obviously, JPEGs don't appear to be stretched out thumbnails, so that isn't what happens. Instead, it's not that high-frequency signals are discarded, it's that their precision is reduced.

Human eyes are quite good at detecting sharp edges and fine details. What they aren't good at is detecting how sharp an edge is. We can definitely see a break between two colors, but we can't accurately detect the magnitude of that the difference.

JPEG takes advantage of that by rounding off those high-frequency variances to nearby values. That means there are fewer possible values at high frequencies, so fewer bits are needed to encode them.

I realize I'm being a negative Nancy here. I really liked your post and I agree 100% on how awesome the Fourier transform is. It's also quite hard to describe it in an approachable way, and you've done an admirable job. I just get bugged when simplifications for a lay audience are actually off the mark.

No, it's not. Telnet sends packets in the clear over many networks controlled directly by third parties and accessible to them as an inherent part of operating their business.

This was a point-to-point cable. The only access possible was physical, by digging it up and splicing it.

Obviously that attack was possible, but arguing that this is somehow "the same kind of attack" as running tcpdump on a router to sniff packets is just insane, sorry.

Also the Mac Pro ceased being sold in the EU from the 1 March (it didn't comply with some EU regulation that came into force — with years of warning — that it trivially could have been made compatible with), so given they had ceased selling it in one major market it would've seemed reasonable to conclude they didn't care about it (and arguably they don't — if they can go without selling any Mac Pros in one of the largest markets in the world for almost a year).

That's not how Alcubierre-derived warp fields work. The time inside a warp bubble is predicted to remain synchronized with the time in the originating frame. Thus, if your warp bubble goes at .95c, it'll take you 105.26 years one way, 210.52 going there and back.

And I'm sceptical of your calculation, anyway. From Earth's unchanging perspective, if your are going at .95c in a conventional manner relative to Earth, Earthlings will see your trip as taking the same 210.52 years. Time dilation will only affect the time that passes for the people on board, which will make it seem shorter, not longer. So, really, if your warp drive can't break c, it's better from the passengers' perspective not to use one. This is explained in the StackExchange article you linked to- you put the factor of gamma in the wrong spot (http://physics.stackexchange.com/questions/31105/how-to-calc...).

>We are, however, not given any details on how his life was bad before the start of this.

The article is littered with details on that topic. Here's the largest and most verbose 'detail':

>One morning back in 2011, I woke to searing pain in my arms. A flamethrower directed at my arms is what it felt like. The hospital offered morphine, but one shot did nothing. A second and then a third shot only made me sob more quietly. Finally Dilaudid, at ten times morphine's strength, cooled off the pain. Several doctors and hospitals later, I was diagnosed with a rare autoimmune disease in which the nerves that branch from the neck and power the arms are bulldozed by the immune system. There's no cure, just a blitz of medicines to blanket the suffering. So I embarked on a grisly medical protocol: monster doses of steroids, antiseizure agents for nerve pain, and a lot of craft beer, ice cream, and chocolate for the larger problem of what it now felt like to be me.
Pimp Your Trello Cards
Well as a professional Systems Administrator, it pisses me off more than it probably should. It's like you want to know why I'm worth what I'm asking because when your shit falls down and goes boom, I'll get you back up and operational in minutes or an hour.

Because it's my fucking job to help you manage your IT risks. Azure, Heroku, AWS aren't replacements for Systems Administration, they're just tools in my arsenal. I don't understand the mentality it takes to go into business (beta or not) without having SOME understanding of your risk. The fact that DO paid you a not insignificant amount due to downtime, means you're damn lucky.
The $500 credit from DO is quite reassuring. Usually if the HD fails and your data is lost, your out of luck. I hear the "horror" stories of some hosts reusing consumer Hard Drivers between servers so learned, Your data is your responsibility. I'm glad the OP had backups but these failures happen, thankfully DO had the business sense to compensate them.

Seems good advertising for DO, as any knowledgable system admin knows Drives fail. DO could have not done anything.
