Something has definitely gone wrong in either the study, the journalism, or with the person who wrote the headline. From the reporting here, there is nothing whatsoever that makes me believe the one minute of strenuous exertion had anything to do with the result.

Why on earth didn't they have a control group that did 10 minutes of slow cycling instead of a bunch of couch potatoes that did nothing? For all we know, the people who actually turned up for the study regularly to do the actual rides walked far further to get to and from the study than the people who did nothing. And for all we know, 10 minutes of slow cycling has the same measurable effect as 45 minutes of cycling.

What on earth is wrong with medical science/science journalism, that this is the end result of however many dollars of public money? Are they worried that if they actually do a really large, robust study that all future funding will have dried up?

Surely there is a massive public interest in such research. Why doesn't someone just do the sodding research and find out once and for all?

Mickey D's: lessons from the giant’s struggles
Don't expose them to hackers then, keep your bitcoin wallet away from the Internet until you want to use it.
The electron goes forward and backward in time and interacts with itself. (In quantum field theory you can replace a positron with an electron going backwards in time). Regrettably the theory does not work, since it would predict the same number of electrons and positrons in the universe.
I think that's what Yelp ended up doing with Eat24, moving the office to Phoenix if I recall correctly.
>Then why does it only happen using bitcoin?

Because some people insist on waiting for the payment to settle before actually providing the services, although it's not nearly as common as it used to be.

This is just completely unrealistic with credit cards where settlement times are far longer than with bitcoin, days or months.

>Wherever you want to lay the blame (anywhere but bitcoin) it's a problem for anyone using bitcoin, making it more useless than (not "immensely superior" to, as claimed) using a credit card or Paypal, which makes it a problem for bitcoin.

I don't know, I use bitcoins to pay for things regularly and pretty much everyone accepts zero-confirmation transactions nowadays (which is pretty much the same as accepting credit card payments, except the settlement will most likely take less than an hour).
I'm proposing regulating the meaningful operator of the ISP business and saying that they are not allowed to set a price for customers of their content business. If they want to sell off the content business, I expect they would still get the market price for their property.

The point is to enjoin the cable company from leveraging content to make competitive offerings less attractive.
Good point! Yeah you really just have to do what you feel. It's okay to try as long as you don't push yourself too hard. There's always tomorrow to run!
> If I felt unwelcome here, I would not like this place, and I would leave it.

> You have to find the place where you fit, or make the place fit you.

This is an extremely ignorant thing to say. I recommend having a read of the history of Koreans in Japan. They cannot just pick up their stuff and leave. Some Koreans like Japan, sure, but others do not because they do not want to change the way many Japanese people want them to.

I saw that you wrote that you have ancestors from Northern Europe in this thread. I assume you mean Scandinavia? If this is correct, by this I deduce that you are White. It's pretty obvious, but Whites have a vastly different experience in Japan. They have a very privileged experience. Most of us know the majority of Japanese (especially women) love White, blue-eyed, blonde foreigners. And even if you don't have these characteristics, you are still viewed as White to them as an American, as long as you are not black, and for that you receive extra special treatment and they offer you concessions because, in their eyes, you are not Japanese, will never be, and will never really understand their culture.

Let me be clear: everything you write comes from a place of comfort, privilege and where people go easy on you because you surround yourself with people who love White foreigners.

Why do I say this? Because I am White and I have been to Japan. Every single person was extremely nice to me, and so I thought these people could never be mean to anyone else. However, I spoke with a family of minorities, some people who are now part of my family circle that I love, and other Japanese friends to understand how the same people that treated me so well treated others so poorly.

And absolutely: Japan will never be my place, even though they treat me with such love and attention. I believe in treating everyone genuinely and equally, though.

I don't necessarily begrudge your lifestyle. I take issue with foreigners in Japan painting Japanese people in such a one-sided way. I can list the many things of Japan that I like, but I feel I need to balance out what you're saying here.

And I'm going to call you out and say you sound exactly like the old Japanese "Baby Boomer" generation who nag the yutori generation (Gen Y-equivalent, if the HN crowd is following this discussion), when it was these baby boomers who have lived such a privileged life during great economic times in Japan. Congrats! You've assimilated wonderfully!
How about this:

-1st round: Submit application (with this we get all submitions and all users that spent time submiting so we already have filtered users that have knowledge on startups)

-2nd round: Every user that submited for 1st round gets to pick for example 3 of 10 other random submitions we present to them that are then evaluated on that votes (This way we avoid ring voting and dumb mass voting. Note that for next cycle we can allow users from previous cycle to evaluate too!)

A "roommate" is typically someone who has a separate room each typically. A shared bedroom would be more of a hostel situation. What she should've done is found a two-bedroom roommate situation first or stayed in a hostel as noted above rather than get a one bedroom place.

As far as my affordability goes, I could manage a one bedroom in this city if I wanted to be living month-to-month and live in the Tenderloin. Someone with the similar responsibilities that I have who is more senior in their career likely has more options.
That's not really true. At its core Money has value as a means to pay Taxes and Debt. If the economy shrinks people need to pay less in Taxes which lowers the demand for dollars. At the same time it's harder to pay debt which generally causes deflation not inflation. Similarly, if the Government spends more than it takes in by "Printing Money" that also devalues its currency.

For really high rates of inflation the only viable option is for the government to print money. EX: If your inflation rate is 18% the economy would have to be 1/5th the size in 10 years and 2.5% in 20 years which just flat does not happen.

I really like your concept. I'm curious how you think it compares to a LaTeX workflow though.

For example, I have MATLAB generate figures and *.tex files containing LaTeX formatted tables. I have C# Solidworks macros to generate PDFs of CAD. If the analysis changes, the MATLAB outputs automatically update, and the same with CAD files. These 'outputs' get picked up by LaTeX on compile. Other than a WYSIWYG editor vs a 'compiler', are there any fundamental benefits to the cadwolf workflow you're envisioning?
That is right and I see most of startups and small business feeling the heat already. I left my last company for the only reason that with the salary they were giving me I could not even qualify for most of the apartments in bay area.

A fine article--but not the awesome analysis of whether one could use a train as a form of space travel that I was hoping for.
PGHoard can archive PG's WAL segments in two modes: streaming directly using pg_receivexlog or as an archive_command to archive complete segments.

When PGHoard is used in streaming mode it keeps reading new segments from PG and stores them in compressed & encrypted form in a queue ready to be uploaded. The segments will stay there until they can be uploaded.

When using archive_mode PGHoard handles the operation synchronously so PG won't actually remove or recycle the WAL segment in question until the command completes.

Postgres will keep running normally in both cases, but the files will be queued in different places, compressed or uncompressed. This may cause your disk to fill up eventually, but PGHoard will trigger an alart after a configurable number of upload failures.
An evolutionary argument like the one he uses is _always_ a big, stinky, red flag.
It's not about "standing up for something better than poverty," it's about having enough sense to not move to one of the expensive cities in the U.S. for an $8/hour job, especially since you can easily become a Lyft or Uber driver and not just make more than that but make enough to commute out here from a place like Concord. Plenty of places in this range in the Concord area:

That's true; but Space: 1999 did it every episode. Most transportation in UFO via. that futuristic car, which they had a full-scale working example of.

I'm sure they showed the moon shuttle a few times, and of course they did lots of effects for the fighter jets and submarines blowing UFOs up, but it wasn't ubiquitous like in Space: 1999.
They had a kickstarter for the preview film (to prove they could do it) and then another for the full.

Also, "fan" might make you think they're amateurs. They're very much not; take a look at the cast and crew list.

I dunno about Watson, but it is my (inspecific) opinion that at least one state government and at least one upper-middle-sized corporation have a bunch of IBM big iron laying around that they don't need.

The real burn is, that's not JUST an upfront cost... You pay per month.

At the corp, I could not find anyone except the CEO that thought the investment was a good idea. I figure IBM gifted him a car or something. Complete speculation, but it's the only thing that makes sense!

Elsewhere, inspecifically... At least the machines are used. But honestly how many giant black modern IBM boxes does it take to fully emulate every single AS/400 machine that existed within the entity back in 1996? A quick look at the specs tells me: 1. There's no way it would take more than one.

The reason I can't put my finger on your reply is that you immediately applied everything I said to yourself and blew it up into a lengthy reply. If you're one of the "good" interviewers, then none of what I said applies to you - that simple. Yet, even if that's the case, I still can't help but notice that your reply then, and now, feels like personal projection of some kind.
Companies start by not having a low-skill, low-wage support staff at all. Then they add it, but they add it locally - in the Bay area, if they're a Bay area company. Eventually, cost wins out and the call center gets moved somewhere cheaper, like a dying Midwest industrial city, or India.

But that sort of move requires a great deal of corporate maturity. It's okay to overspend in the name of short-term convenience when you're still kind of a startup.

> An electric car shares most of its parts with a gas one

Definitely depends on how you qualify 'most'. An electric car has nearly none of the mechanical complexity of an ICE car. Look at the engine bay and undercarriage of a typical internal combustion car:

http://i.imgur.com/uDxSsR2.jpg

Gas tank, fuel lines, transmission, engine, drive shaft, spark plugs / distributor cap, muffler, exhaust system, fuel pump, engine, air intake, turbo/super chargers if necessary, oil pumps / reservoirs, etc. -- many hundreds of parts can be shaved off of full electric cars.

I'm firmly in the camp that Tesla is going to have a much more difficult time that people predict in shipping a mass-market car, but that doesn't change the fact that it's much easier to build an electric car than an ICE one.

Issue 161127 in chromium: JavaScript source is occasionally corrupt (2012)
I wouldn't entirely agree. If you aren't lifting any relatively heavy, extra weights, e.g. running or something, warming up isn't as important. However, when lifting relatively heavy weights, I think warming up is pretty important.

Warming up has the benefit of lubing up your joints. I think we've all had the instance where our body are relatively stiff and if we do, say, a push up, our joints pop or make cracking sounds. I remember squatting once when I didn't fully warm up. My knee wanted to pop during the squat and it felt extremely uncomfortable trying to exert force on that leg. When there isn't any extra weight, merely extending your leg with a pop wouldn't bother anybody, but exerting a lot of force and doing so slowly sure wasn't a pleasant experience. What are the chances of serious injury? I don't know, but it hurt enough for me to not want to find out.

Another thing warming up helps with is to acclimate you to your working set weight. I know the first set of my bench press usually ends in a grinder and is the roughest out of all my sets. I'm not sure if it's just my mind acclimating to the weight or a physiological thing like more blood getting pumped to my muscles. Either way, I'm fairly certain (but do not have any sources) injury rates would be increased if you tried to deadlift your max without properly warming up.
Option.get is important. It lets you work around the type system in cases where the type system wasn't expressive enough. Given that all type systems are imprecise, this functionality is essential.

I'm all for strong type systems, but I also acknowledge their limitations.

> would do corporate accounting for free (let's assume this guy exists)

The problem is that it's estabilished as the new norm. Instead of accepting that maybe 0.1% accountants are passionate about their job and thus getting hiring like that is just a super-lucky coincidence, they actively seek them, forcing people to pretend about their passion for the job.

As a consequence, the companies lose candidates who would make excellent accountants, but are not able or not willing to lie during the interview. Another consequence is that people are generally unhappy to work in a place built on bullshit.
Sounds pretty biast. I mean anyone could code...just like anyone could be a plumber...whether you're great at what you do is the differentiator.

Neural networks and image recognition applications such as self-driving cars have exploded recently for two reasons. First, Graphical Processing Units (GPU) used to render graphics in mobile phones became powerful and inexpensive. GPUs densely packed onto board-level supercomputers are very good at solving massively parallel neural network problems and are inexpensive enough for every AI researcher and software developer to buy. Second, large, labeled image datasets have become available to train massively parallel neural networks implemented on GPUs to see and perceive the world of objects captured by cameras.
Viacom, Comcast, Disney, CBS, Netflix, Amazon, Apple, Twenty-First Century Fox, Google, Verizon, AT&T.

Those are all massive media companies, we very clearly do not just have two. Apple is by far the world's largest media company. Amazon is a $300 billion, hyper aggressive corporation that is doing everything it can to become a big player in content. Amazon even has its own infrastructure play in AWS, which is responsible for delivering all of that content (ten years from now, will people be arguing AWS is a utility as it becomes as big as a major cable company?). Netflix is a fast growing $40 billion corporation.

AT&T and Verizon are as much media companies these days as Comcast is. Verizon purchased AOL and would seemingly like to buy Yahoo. Both AT&T and Verizon are as big and powerful as Comcast is.

Even Google continues to push further into that field. After all, how are they not partially a media / content company, given they control the world's most used app store (reaching a billion people), and have competing products in content delivery (video, music). Google even has a direct competitor to Comcast in Google Fiber.

Depends very much on your requirements. If this is data that is rarely changing, and that you have complete copies of, that is exactly what S3 is not good for. In that case: Any dedicated host that's cheap and with reasonable latency (or put a CDN in front). Two copies for failover/ha if you need it.

If you pay more than 20% of the advertised rates of AWS bandwidth, you're being robbed. 10% or less is doable.

If you need durability guarantees, consider if the cost problem is storage or bandwidth. If the problem is bandwidth costs (in other words: your data set is small and accessed often), store at S3 or Backblazer or similar, and place a server or two at a cheap bandwidth host with Nginx and aggressive caching policies.

I've done this for a couple of customers who did not trust other data storage options with their data, and you can rent a server + multiple TB of transfer for a fraction of a the cost of 1TB transfer from S3....
