Congratulations on the book but the formatting is very poor for a technical book. 10 words per line is good for a small paperback sized novel not for a technical publication. The excessive white space, the line spacing are also inappropriate. The most important element (arguably) - the equation also is the hardest to read due to the small size and how compactly it was formatted. If you've paid for the formatting as a service I'd try to get a refund and give it to someone more competent.
We have the funding we need to bring the product to market (an odd downstream benefit of Oculus getting bought by Facebook), but we will be taking pre-orders with a deposit prior to shipping to make sure our SKU mix and production rates are matched to actual demand.

We won't be asking consumers to pay a premium for longevity, but it's nice to hear that you'd be willing to!
I would like to see a chart that predicts the price of bitcoin and multiplies the predicted price with the block reward. The dollar value of the block reward is the profit motive of miners. If it goes down over time then Bitcoin will consume less and less power.

However, it's entirely possible that block reward halving will also accelerate the deflation of Bitcoin as more and more Bitcoin get lost irreversibly.

We are the point where things can get better or worse but nobody knows yet.
All of this information has been available on android for years.
It's amazing how little HN readers understand about unions. A company is an organization that has some positive and some negative aspects.

And believe it or not, a union is also an organization with some negative and positive aspects.

The difference is, once you have a union in an organization its very hard to dislodge it no matter how dysfunctional it gets.

I would suggest HN readers read about what UAW did in the auto industry, particularly the way the auto union functioned at the Toyota NUMA plant in California.

Then they should read about the corruption at the Teamsters (I'm sure you have heard about the collusion between union bosses like Hoffa and the Mafia). The high profile corruption is just the tip of the iceberg. Even your local teachers union has a tremendous amount of nepotism and corruption ... its not at all meritocratic.

And the worst part about a union is that it turns the workplace from a zone where we are evaluated based on our output into a zone where politics dominates when it comes time for compensation and promotion discussions.

I will never again work in a unionized workplace ... and thanks to getting an education and learning how to program I will thankfully not have to do it ever again.
Great initiative, but the proprietary expansion cards are entirely counter-productive to maintainability.

The expansion cards will only be available for as long as your company provides them. Using the most-commonly used, mass-manufactured standard interfaces for components would provide more long-term repairability and upgradeability.

The trade-off would be in design resulting in more bulk and in the economics of your company, of course. It seems cynical to me to sell maintainability while starting a walled-garden ecosystem of proprietary hardware.
I like the points about using php for logic instead of mysql, I've been doing that for years because I prefer to always do the heavy lifting in php which I know better than SQL.

I always felt it was against best practices though, but now I won't worry about it so much.
A friend pointed him out to me. I don't know how he came to find out.
This has crossed my mind a lot of times and I think the comment is right - market capitalization of index cannot increase to infinity. There is a finite number of companies that the Index is comprised of and there has got to be a theoretical upper limit to that.

Moreover, the investment psychology also comes into play here. The growth rate of index may slow down as it becomes large because investors always compare today's index with the previous values and are likely to conclude that the index is "over-valued" if it keeps rising.

I'll be curious to find evidence of deceleration as the index value rises.

Nothing. He merely takes responsibility for it in one of his tweets, and subsequently claims it wasn't a DDoS.

How reliable is this source? I've never heard of Vator TV, but it seems like Groupon is worth a lot more than $2.5b if they're making $50m/month while they're still relatively young.
You can make a lot of money on open source (Red Hat, Wordpress.com, etc), but you have to approach it from a whole different perspective and business model.

What is definitely a lot more difficult, even impossible, is the insane level of valuation that closed/proprietary companies have (ie, facebook, twitter, etc). Which means that your valuation will have to more accurately reflect your revenues and profits.

Which may not be a bad thing. It definitely makes it harder starting out, VC's are still very wary of open source, but it keeps you more honest in the long run.

If you're looking to get big fast, and cash out early, go proprietary, and ride the wave. If you want to build a solid company, you can definitely do that with open source.
I have several concerns with index fund/ETF investing:

1. How much of the underlying stocks, that make up the Index, are really owned by the Index fund/ETF? I doubt that such funds/ETF actually own 100% of the required underlying stocks, may be using some sort of option/hedge strategy.

2. In what scenario, not owning the actual underlying stocks can be detrimental to index fund/ETF? I am looking for what may cause failure of such funds/ETF and who may lose.

3. Is index fund/ETF investing artificially inflating price for underlying stocks compared to price of the rest of the non-index stocks in the market?

4. Can index investing cause Index "Bubble"?
Excellent point your research suggests:

Not stupid. NOTE: Not my field, so speaking off basic knowledge here. Happy to be corrected.

Tl;dr: because biology at scale is complicated.

Longer-form, because antibodies and immunological response are somewhat complicated. Knowing what an antibody looks like, how to produce it, and how to scale that production in a safe and reliable way are all very different things.

Older article, but general concepts: http://neobiolab.com/research/in-vitro-and-in-vivo-productio...

... And because the in vivo methods we know of are ethically dicey. To rephrase it in rough terms -- creating custom cancers that produce the thing we want and giving them to mice, then harvesting concentrated antibodies from the tumors.

I'm going to completely disagree with this, particularly as the OP has stated he doesn't have a high-school degree, so a college degree is likely out of reach.

I don't have a university degree, and the only times that has stopped me in an interview process is places that I likely wouldn't have wanted to work anyway. Even Google, which prefers people to have a university degree, will make an exception if they see you've got the experience and capability. This is speaking from experience, though I dropped out of the Google interview process as I needed a visa in shorter amount of time than they were going to take in making a hiring decision.
Sure, caloric intake is up. But we don't know whether calories per capita per day increasing is a cause, an effect, or both. Maybe all it means is that something changed to make people hungrier than they were before. For instance, there's the "fat virus". It's possible that obesity is literally contagious and more people caught it with, say, the growth of air travel.

Yes, there is an overarching conspiracy by the Apple cabal, led by Jobs' reanimated corpse, to bury your comments and keep The Truth away from HN.

Your comment being factually incorrect does not come into this issue at all.
I planned a google ad campaign with a 200 TOTAL budget.
A google representative helped me setting up the account, after 4 days she calls me back and said that my ad is doing very well,
And it’s already holding at 800$.
Till now google didn’t give me back my money with claiming that I don’t have prof. They are not willing to listen to there own phone systems recording’s because they know that I’m right.

Ingress and egress costs are expensive in the cloud. Using this with gzip could save you on cost.
In a way it's true that we transport things too much - but container ships are extremely efficient compared to almost all other means of transportation. The thousand miles in the 18-wheeler is probably a far larger part of the transportation emissions than the container ship from China.

So it might be more efficient to make a large investment in the American railroad network and start removing trucks from the road, than to start making toothbrushes in the US.
The gilettes jaunes are on the streets, nobody cares to make them cultural icons. Gays had very visible and generally disproportionate (compared to population) media coverage of their rights. Was it really 100% due to activists on the street, or very influential but high profile gay people who helped build one of the few successful rights movements of our times?

I think you're right. Our current form of global trade can only exist by exploiting a kind of lawlessness that comes from being able to distribute owns company beneficially across uncoordinated governmental regions.
Damned if you do and damned if you don't. Nice. You'll change your tune if you ever find yourself in that situation.
As all detector arrays, digital sensors have a fingerprint/signature/profile [however you look at it] that can affect noise/(d)efficiency/colour etc.

This used to be all too apparent, even Kodak digital cameras had a correction-filter file calibrated for each camera to adjust white balance etc. that came with the camera.
There are cases where a relatively maintenance free power source which can be installed a point of use is worth a lot more than you'd think -- it's basically like a primary battery cell -- a way to transport energy. It doesn't matter if it's less than unity efficient in recovering the power used to make it, if distribution and storage costs for that power would otherwise be really high.

On cellphone towers in the middle of nowhere with no wirelines linking them, a solar panel makes a lot of sense, even if it never recovers as much power as it cost to build. Or on a satellite. Or, apparently, on a shack in rural Africa.

I agree Africa probably could do better with natural gas, oil, hydro, or coal central plants for now, vs. big solar plants, but a combination of cheap big grid power sources and decentralized renewables seems like the best solution. Building out a grid in rural areas isn't really cost effective.
Also an emphasis on the importance of family and how that relates to business, e.g. handing down family owned businesses to sons.
Erlang syntax is derived from Prolog syntax, sure, but with several extra operators and heavy operator overloading. Prolog syntax is cleaner.

The ";" vs "." thing is also on Erlang. Prolog has a function to read the next clause (much like Lisp's read parses the next sexp), and Prolog clauses end in ".". The Erlang interpreter seems to have been implemented so it read every alternative for a pattern in one step, so it ended all except the last with ";". ";" is Prolog's "or" operator, "," is "and". Prolog just ends every pattern with ".".

That said, you get over those minor syntactic issues pretty quickly, and I'll take a language with ugly syntax but beautiful semantics over one with ugly semantics any day.
Another FYI after browsing the report: questions were asked in 2007 about income in 2006.
tl;dr; Out of 3 lines, yours will be the fastest only ⅓ of the time.
She specifically says to go with slow disk I/O (not in-memory indices) because the most important thing is not to have to deal with failing servers.

This was written in 2004, and the equivalent statement would be that you should not deal with maintaining physical servers but have the cloud handle it so you can focus on algorithms/parallelism/runtime.

Also, unrelated to what you wrote, this is 2004, and statements like "people search for words not phrases" are frankly no longer true. Average query length is way up (even before google suggest and instant) and people have been searching for phrases more and more since 2004.

She's completely right, but if she were to rewrite this today, in 2010, it would be an even longer article. A single-word search engine would not return acceptable results.
Sure. Profiling and incremental tuning has been sufficient so far. It will probably be hard to scale indefinitely, but HN already handles quite a bit more traffic than many sites.
Indeed. It would help not calling them by a generic "Stem Cell research" name . Yes, some cell sources fall in the grey, almost black part of the line, but there are other being completely safe and out of ethical concerns. For example, discarded Placentas are full of them and doctors throw them away anyways.
Don't forget about adult stem cells, too. Those do count.
"... but I'm never depressed, just unable to convince myself to take any other path than the easiest one (e.g. fast food instead of home cooking, Short stories instead of novels, video games instead of hobby coding, organizing my computer rather than cleaning my house, etc.)"

That sounds a lot like depression to me. Depression isn't always sad or melancholy, sometimes it's just like you said.
eBay does not actually need a lot of infrastructure in a new market (relatively)- int's all server based. Amazon is a another story, with their inventory approach requiring critical mass of warehousing close to market.

eBay are famous down here in New Zealand (at least with those that care) for believing that serving a dial-up market with heavy picture laden HTML from 200-300ms away and no local presence was going to work. A local start-up (Trade Me) destroyed eBay pretty quickly and has gone on to post better per person numbers than (I believe) any eBay affiliate.
Same story in China. I say there are/were too many MBAs in eBay and not enough (especially local) tech-heads.

Meanwhile Skype is doing great things post eBay ownership.

But don't just have one test for your hypothesis. Have many. Seek to improve your hypothesis.

The end result should be an organization with a theory about how it does business. The gift that good founders have that others don't is the knowledge of what that theory was, the key assumptions it makes, and how to tinker with it.

> The thing that chaps our asses is that it's almost exclusively used where a simple circuit would have done fine, often boiling down to being just a 555 timer or a parallel port breakout box.

So what's been lacking in the nearly 40 years since the 555 was created that it's taken until now to get some of the people who are now working with electronics to get started? (Aside from needing to be born. :) )

Your definition of "simple circuit" is probably different from the majority of the world.

And you're correct that the majority of what makes the Arduino what it is, is software. I describe it as being popular with software people because it took what used to be a 100% hardware problem (your 555 timer "simple circuit") and turned it into a 90% software/10% hardware problem.

The Arduino has got more people into creating tangible electronic devices that operate in the real world--I think that's a good thing--who cares if they don't know what Kirchhoff's circuit laws are before they get something that works.
"Of course, the downside of the American culture is that the way politics gets financed (with the Obama campaign as a positive exception) seems a bit sketchy at times. Not that our own system is preferable, because we've taken it to the other extreme and have our government pay for the election campaigns of our politicians in order to avoid the suggestion of political debt to private benefactors."

You are correct that Obama financed his campaign in a way that was significantly different than any other U.S. presidential campaign in three decades. However, I think that you misunderstand how our presidential campaigns are financed, and especially how Obama's was financed differently.

For decades (ending with Obama), our presidential campaigns were funded by a mix of public and private money. In return for agreeing to additional restrictions and oversight on their fundraising and spending, presidential candidates in the U.S. are given government-provided funds to match contributions. The advantage to this is obvious: loads of extra cash. The disadvantages are that the candidate's campaign spending is subject to additional rules and regulations, and his total campaign fund is effectively capped by the accompanying restrictions. However, this limit is so high that for most of the program's existence (it began in 1976) there was no practical way for a presidential candidate to raise more money on his own than he could by taking the matching public dollars.

Obama changed that: he refused public campaign financing and directly raised more money than allowed for by the limit on public financing. Now that he has shown it to be possible, it is likely that every major-party presidential nominee from now on will follow his example and refuse public campaign financing. This means that their spending will no longer be subject to the full scope of rules which previous campaigns operated under. If you believe that wholly public and wholly private financing are undesirable extremes and that some sort of middle ground would be preferable, then you should consider the Obama campaign to be a negative exception, not positive: he took U.S. presidential campaign finance away from an intermediate state and drove it straight to the extreme of wholly private financing. Personally, I was never a fan of public campaign financing and am happy to see it made obsolete, but if I'm reading you correctly you find wholly private financing to be "a bit sketchy."
Looks like OpenRasta has a pretty solid community built around it and the general design abstraction looks pretty good.

Kayak also looks pretty nifty, but seems to be in a bit of state of flux at the moment (more so than OpenRasta).

Both added to the shortlist though :)
I did not know that, thank you. I guess the key is in the phrase "as long as you got the right libraries"? Kernel+X alone is not enough... There should be some simpler solution to this than deploying your app in a container, but I really don't know enough to even dare guess.

perhaps the problem IS the SAT system. I have a high IQ, and I can't for the life of me understand why the US uses SAT's which are so similar to IQ tests. In Australia, the HSC required me to work, and people less smart than me who worked harder beat me.

The SAT's on the otherhand, encourage a feeling of "giftedness" and unwillingness to take risks. If I had to just deal with the SAT's I would be lazier than I already am!
I've seen some pretty impressive scale at markets in other countries, bargaining and all. Perhaps its Walmart that's the misfit?

Not only that. A vdev with 15 disks each around 16 (or 18?) TiB with RAID-Z2 just asking for troubles (https://www.zdnet.com/article/why-raid-6-stops-working-in-20...). Even with 1% disk failures annually (based on Backblaze, for better disks), we are looking at least two disks fail at the same time with 15 disks around 1% chance. With 10 vdevs, that is 10% chance of any of these have failures.

They should really move to RAID-Z3 or 8 disks group. With RAID-Z3, we are looking at at least 3 disk fail at the same time with 15 disks around 0.04% chance. With 8 disks, we are looking at 0.2% chance.
Because a human putting 5 in the field for 1+3 is an isolated mistake, but the machine doing it is the result of a deterministic process that is likely to occur much the same way over and over again.

In other words, no, we don't ignore MCAS causing the plane to go into a stall under some isolated circumstance just because humans also put planes into stall.
Okay, I still don't understand your point.

BTRFS stores duplicate copies of the metadata. Good for BTRFS. I don't understand how this would have prevented what LTT experienced.

First, as someone else said -- no one would use a BTRFS raid5/6 array in production. No one. Second, I don't think what LTT experienced was bit rot. There were far, far too many data errors for that be simple bit rot. My guess is bad cable, bad HBA which maybe doesn't support something like ASPM, etc. Third, are we even sure the problem was corrupted metadata? Fourth, ZFS keeps redundant copies of metadata too (as do many filesystems.)

So the question is what's your point?
