You're not alone. I listened to a podcast a while back on this subject, and the reason that the blood "market" runs solely and strictly on donations it's because earlier in history, when the medical establishment paid for blood, they were only able to get skid row types to contribute, and needless to say, the quality of the blood wasn't good.

how do carbonated sugary drinks become less safe than non carbonated sugary drinks if carbonated non sugary drinks are safe?

It seems there is a missing item somewhere.
Thanks for your comment.

I don't know if I can get professionals who specialise in emotional intelligence here in Bangalore (India). Most psychiatrists I can see online have "drug rehab" like words highlighted.

More physical activity is what I gonna do next (will join a gym next morning). Changing activities is something I wonder how I can do. I spend almost all my time on computer, it has never been a problem until now. And I have changed places a 3 months back. I came from my home to Bangalore dreaming of a city overflowing with tech geeks (although all I could find were people doing their "jobs"). And I don't think I can leave it for few months, I am 100% on my own in this city; in a month I will run out of funds and have to get myself fit for work before that happens.

> If you need anything you can contact me.

Thanks. Your words are enough, I think I am the only one who can do something about anything else I need.
Two other possibilities:

* In the private health-care world, if you're getting paid, you might feel like someone else is profiting off your blood (how else could they pay you?)

or

* In the public health-care world, if you're getting paid you might feel like money is being ill-spent when it could/should be used to better pay healthcare workers etc. since people are typically willing to donate blood for free.
If I assert that a man runs, I might mean that he flows under pressure, but you would probably interpret me to mean that he moves quickly on his feet. "An organism evolving" similarly tends toward one particular meaning. When you then say you mean to be "within the bounds of scientific discourse," how can you blame someone for thinking you are using the scientific definition?
OneNote for Beginners
Just a note: I think I was hoping (but didn't confirm) that I was downloading the key from GNU and the file from a mirror. So I thought I had the minor protection that I was at least safe from somebody who could only alter the mirror. But I agree with the criticism: not being clear what you are claiming to actually check in a crypto-situation can confuse others and cause harm. Sorry about that.
No, it's about the safety of the blood supply. It's a weird quirk of human psychology and economics that paying for donations means fewer healthy people and more people with infectious diseases donate when it's fee-for-blood.
Preserving Technical Knowledge
The IT at the company I work for is odd. I work for a smaller subsidiary that manages most things for itself but we're still required to have a parent company approved workstation alongside our main development computers.

So I have this dinky little HP with a 15" monitor just to do the HR computer "training" stuff related to our industry and then I have a full size workstation with dual 24" monitors that I develop on. They're connected to different networks, my workstation is on a Comcast business line and then the other is on an internal network that has the strictest security policies on the planet.

It's like having a weird cross between IT as it should be (as described in this article) and IT hell you expect in large corporations.

Looks like they have tested a newer kernel too:

https://github.com/fastos/fastsocket#nginx

>on Linux 2.6.32 achieves 470K connection per second and 83% efficiency up to 24 cores, while performance of base 2.6.32 kernel increases non-linearly up to 12 cores and drops dramatically to 159K with 24 cores. The latest 3.13 kernel doubles the throughput to 283K when using 24 cores compared with 2.6.32. However, it has not completely solve the scalability bottlenecks, preventing performance from growing when more than 12 cores are used.
Firebase is geared towards building applications that need to update their data in realtime. When you change data in Firebase (either by adding data or modifying something that's already there), all connected clients are notified of the change, allowing you to update your UI to match the new data. While many people use it as a backend, it really shines when you take advantage of these notifications.

If someone has to drive across an international border and take a day off work to donate their (very rare) blood, it makes sense to compensate them for their travel costs.

The donor wouldn't have to also be "donating" gas money, just blood and time.

Back in the 90's Microsoft tried it's "embrace and extend" dirty trick on the nascent Java environment (have a look at Wikipedia's entry on the infamous J++: http://en.wikipedia.org/wiki/Visual_J%2B%2B

They ended up severely burned after that, none the less because they got the anti-monopolty demand during the browser wars.

Worth mentioning that POWER is the only chip I'm aware of that has hardware DFP instructions.
GUI tools are nice in some situations, but I find they mostly slow me down. When I'm using Git I want to be fast and a hot-key command window plus the command line is about as fast as you can get.
I'd argue that the one tool you need is something like git to make those small isolated snapshot copies for you. Learn a few commands and you won't have to worry about an ever-growing pile of directores that will just metaphorically topple over eventually.

Then you can make changes ad hoc with confidence that you can quickly and easily revert if something breaks, without having to organize a smattering of cloned directories yourself.

I guess what I'm saying is, the highest ROI for version control is to learn git add, git commit. At least you have the history well-organized for you down the road, with minimal effort on your part. If you need to revert at some point, you can just figure it out when you need it.

This isn't a good idea. Why? Because it takes IT from the position of being a roadblock, which is something you can push to get fixed and puts you in the wrong instead.

IT has valid reasons using RHEL and older packages, you presumably have valid reasons for using newer packages. If newer packages are needed work with IT to get those newer packages. This also means that they are back in the position of being a roadblock if critical projects really can't go forward due to their policies.

Sometimes the way to fix what is broken is to make your department stop being a crutch for failed IT policies.

Also, randomly changing system packages in production is a dick move. That sort of shit is (rightfully) going to result in getting your access revoked at the minimum.
Let's consider the effects of a tax on internet service providers. Critically: the tax is levied in Hungary, but not in surrounding countries.

The average household net-adjusted disposable income per capita in Hungary is $15 240 [1]. At 60¢ per GB, the tax is not breaking household budgets. Neither should it be onerous for bootstrapped small businesses. Moving hosting out of Hungary would mitigate most of their tax burden (live media would be an exception).

The case becomes more interesting when we consider scaling. Few businesses today can compete with underpowered IT. The bandwidth needs of a business's IT operations can be assumed to scale with the enterprise. Speaking as a financier, this sets up an easy transaction. If your business scales, move it out of Hungary. The benefits of offshoring scale with the company.

Avoiding that incentive structure is probably why we see the corporate tax offset. But a tax deduction is only of value to profitable companies. This turns the linear scaling disadvantage into an option-like structure. If you scale AND experience losses, there is a penalty for being in Hungary. The more cyclical or volatile a company's earnings, the greater the risk of incurring the tax and thus the benefit for offshoring. If I were a European M&A banker, I'd be working out the ceiling on earnings volatility a Hungarian company would rationally tolerate given this tax. I'd then run through the stock market and private holdings records and begin working to merge those for whom this tax would be risky out of Hungary.

Start-ups are also loss-making business entities. For a bootstrapping Hungarian, the cost of relocation isn't worth a few hundred dollars in tax savings. But for a VC it may be. If I were Austria, the Czech Republic or Poland, I'd offer every Hungarian entrepreneur a deal: We will lend you money for relocation. You repay it at 1/2 the tax we estimate you would have paid in Hungary. If I were a European VC, I'd be dusting off a recruiting pitch for bright Hungarian engineers and entrepreneurs.

This whole deal, from the moment Elop went to Nokia, was a disaster in slow motion. That the current Lumias are so good, yet sell at unsustainable levels, shows just how fundamentally flawed Microsoft's strategy has been, and continues to be.

They've been solidly outplayed at their old embrace, extend, extinguish game, and unless they can get back into that mode mobile will just be dead to them.

And I say this as someone that would welcome a strong third player, because the App Store/Play Store duopoly is stagnating fast.
Police: Men wearing GPS devices raped, killed 4 women
An interesting point, but for me at least there is a significant difference between earnings and reimbursement. One might be more likely to donate if they're not being paid, but if they knew that donating involved spending a non-trivial amount of money that would not be reimbursed I think it would be a deterrent.
I'd add the .gitignore file to the guide, with a link to a site like http://gitignore.io.

I think it's both easy and important to learn early that you don't want to commit binaries and push them around with git.
Felt like this was interesting from a "refutation of pro-tracking arguments" standpoint.
Thanks for the pointer. I highly appreciate that.
While LimeChat is a nice & free IRC client on a Mac, it still has (had?) quite a few rough edges the last time i've used it.

I've since switched to Textual, which has its foundation in Limechat (it's a fork of it) that has since expanded quite nicely - both feature-wise as well as UX-wise.

Buying Textual costs 5$ but if you're cheap and can compile stuff yourself with Xcode, you can do so.

I'm in no way affiliated with Textual, just a happy customer...
So instead of using a tool that does all this for you, he should do it all manually, himself, in the most tedious way possible? I mean if he was aiming to learn about version control this might be a good approach to teaching the pains that it solves, but git does all this with approximately 4 pretty painless commands: git add, git commit, git log, and git diff.
I am not aware of whole blood cryostorage for use in transfusions after thawing from -196° C, can you please point me to the literature on this?

What I could find via Google searching referred to specimen cryopreservation at this liquid nitrogen-low temperature, and retrieval for future analysis and umbilical cord/placental banking for stem cell retrieval, but not for whole blood banking.

One question: could CurrentTile.hs be DRYed up? https://github.com/egonSchiele/chips/blob/master/src/Chips/C...

This repeating pattern seems ripe for DRYing:

checkCurTile (Chip _) = do
liftIO $ playSound (soundDir ++ "collect_chip.wav") False
tileAt Current .= (Empty def)
checkCurTile (Gate _) = do
liftIO $ playSound (soundDir ++ "door.wav") False
tileAt Current .= (Empty def)
checkCurTile (KeyYellow _) = do
yellowKeyCount += 1
tileAt Current .= (Empty def)
checkCurTile (KeyBlue _) = do
blueKeyCount += 1
tileAt Current .= (Empty def)

Git was a little abstract for me to comprehend easily using command line so I just didn't use version control. The concepts made sense in theory, and I knew there would be benefits, but it was difficult to really wrap my mind fully.

I recently began using Tower which gave me some visual cues to the concepts others seem to more easily be able to visualize in their head. Once I get more confident in my workflow I may go back and try using Git from the command line again to see how I like it.
It is kinda embarrassing for a digital publishing tool for web to have broken justification on their front page so prominently. Both IE11 and Fx35a2 just break words at random places without hyphens, and Chrome 38 won't even try and right aligns the paragraphs.
Loss, Sacrifice and the Space Elevator
I love the idea of small scale stock offerings, but isn't this illegal? My understanding was that selling stock like this is a private equity offering and that private equity offerings are limited to a small number of people unless the investor is sufficiently rich (the government likes to use the term "accredited investor").

>"The Silver Line is pretty expensive for what it is, but I think you're overstating it. If I understand the Wikipedia page correctly, the $6.8 billion figure is for the full 23 mile extension, not just the 11.6 miles built so far."

You're right, I did mistate the length.

In general though, I think you're misunderstanding my thrust here. You're talking about value, I don't think this project is a good value at all, quite the opposite [1].

I'm just thinking about engineering and construction...

The Silver Line is a demonstration that building 23 miles of 45 mph commuter rail line costs at least $6.8B despite the benefit the benefit of 40 years, 100+ miles and 90 stations worth of experience doing the same.

Given that, actually building a first of it's kind 40 mile 300 mph rail line through the same sort of aerial and tunnel requiring [2] suburban counties around DC for 'only' $10B seems completely implausible.

Placebo effects include biological responses that can be measured in objective ways such as heart rate and blood pressure, observable allergic reaction, immune response in blood samples, or healing of tissue. For some drugs for psychological problems, we can measure the effects of a placebo medication/procedure/ritual causing release of dopamine in specific areas of the brain - again, an objective measurement of a real effect caused by the placebo treatment.

The effect of placebo's certainly is not limited to subjective feelings of improvement, it actually causes people to not only feel better, but be better up to a certain amount. Some medicines give significantly better results than a placebo, and some medicines, well, don't - so in that case they're probably placebos in essence.

I'm not even sure if what you describe would be called a placebo effect in medical literature - if objective measurements say they're doing awful, then we count it as a failure, period, and not an expression of the placebo.
Ask HN: Strategies for marketing android apps and increasing user base
I recently published an app to the google play store called Connect the game. I have had a couple of downloads but no real feedback as to the quality of the app. I believe that I need a larger user base to get the feedback I am looking for, however I have kept the development costs extremely low and don't have a lot of capital to spend on marketing, are there any low cost marketing strategy suggestions that could help increase the user base so that I can get better feedback?
