A miner that successfully mines a block collects all the transaction fees for transactions in the block. They are high right now because many people want to send transactions, but blocks are capped at 1 MB, limiting the number of transactions that can fit into one block. Blocks are produced approximately once every ten minutes, so a transaction that contains a fee that’s too low will constantly get passed over in favor of higher-fee transactions.
Again, useful applications being crowded out by speculative ones. Why bother making anything if you can apparently trivially print money. Until the bubble ends.

> where do these transaction fees go and why do they have to be so high?
They go to the miners who verify transactions. They're high because of the combination of the overall ridiculous price of bitcoin (since the miner gets paid in bitcoin) and the amount of computing power required to successfully mine. The latter means that miners are only willing to verify if the return over time will turn them a profit on the cost of hardware.
Not specifically to you, but want to point out that you cannot have secure + decentralized + anonymous without being subject to poisoning attacks.

SafeButler (YC S17) is hiring engineers and ops to modernize insurance
Solving our own pain point, we are automating insurance shopping for American consumers. After a quick signup, a consumer's insurance shopping and management are put on autopilot with us. Better deals automatically come to them for the rest of their lives. Switching takes only a single tap. It will save consumers time and money while giving them better protection.

Bugs in our system could mess up people's lives big time. If you take pride in writing code that "just works", if you love turning an idea into a deployed feature in minutes, you'll love it here. Practical experience with Python/Django, SQL and automated testing strongly preferred. Practical experience with Ruby/Rails or Java will be considered too.

Please contact jobs@safebutler.com. We are a 4-person team based in Newark CA (across the bay from Facebook HQ). The company is backed by a group of angels, including YouTube co-founder. At this point, Bay Area candidates with US citizenship or greencard only please.

To be fair to some of those executives their red herring dream of Hydrogen Fuel Cells offer all those same benefits: a Hydrogen Fuel Cell car at this point is just an electric car with a strange "battery" that needs to be refilled like a gas tank.

That's why Toyota hasn't entirely fallen behind in the Plugin Hybrid Electric Vehicle, despite investing far too much in Hydrogen Fuel Cell Vehicles. The PHEV for them is a side-game that benefits directly from a lot of the money they are throwing trying to make HFCV work, simply because they can use the same electric engines, regen breaks, etc, despite many of their executives apparently still thinking that batteries are a fad waiting for Fuel Cell infrastructure.

> Here's a question: will the iPod have a retro comeback moment, as electro-mechanical media like vinyl records and even cassettes have had?

The iPod is a brand and not a product category. The analog, would be standalone digital portable media players having a retro-comeback, not then iPod itself having one.

> Or maybe once you cross into the digital divide, does the experience and associated nostalgia perhaps not work the same way?

Quite possible; is there any aspect of the experience with iPods or other standalone players that is lost using multifunction digital media devices like smartphones?
I've driven in an electric vehicle, I had a great time. That being said, you can show why electronic will continue to struggle using an Excel spreadsheet.

Batteries have come a long way, making electronic expensive but workable, but even then 30 minute fast charge times are a bottleneck for general acceptance as is the range they can put in a sub-$30K vehicle.

And even the above might not be a hunderance if hybrids didn't exist. Problem is that electronic is competing in a marketplace with hybrids able to be "recharged" at the pump in minutes, with superior range, lower prices ($23K start for a Prius), and even the ability to be plug-in for all electric short journeys (e.g. Prius Prime).

I'd be lying if I said I didn't want a Model 3, but they're still right overall.
Even if you don't run OpenBSD, you almost certainly use code written by the OpenBSD project—probably in a security-sensitive context.

Finns remember it happening before, for the reasons stated in the article:

Just substitute Russia for "the Soviet Union", NATO for "the Germans".

Yes, I'm old enough to remember how glorious it was that, as a kid, you would be unreachable most of the day without even your parents freaking out. I think smartphones are a small piece of a current dystopia.

I can turn off my phone most of the day and still interact with society, though. A ubiquitous AR has a high probability of being nightmarish ~50 years in, IMHO.
I feel like this is a rewriting of history. I knew literally a single person with a mac when the iPod came out, and they were not the first person I knew with an iPod.

My recollection of the time was that most MP3 players were based on Flash storage rather than HDDs, so I could get about 10 songs onto mine.

Macs didn't really take off as a thing until long after iPods had been mainstream for a while, so I don't think the integration was actually very important compared to the fact that there was a well known HDD-based MP3 player.
I still use my click wheel ipod. The UI makes finding my songs much quicker than on my phone, and it can create on-the-go playlists just by holding down the button, which Apple still hasn't figured out how to do on their phones. And finally it has a high quality DAC so music sounds better than from my phone.

I experienced this when I lived in Honduras, C.A. Avocados from Mexico and indigenous Honduran avocados cost the same as Canada, my country of origin. It was a shock to me as I immediately thought of the locals, however for a number of them they have their own trees that bear fruits/vegetables for them allowing them to bypass purchasing these food items.
Thanks for sharing Nick! Happy to answer any questions you guys have on GoRails, screencasting, etc.
I haven't had to pay full price. But, last year I had to pay 20% of the cost. It gets out of control fast since I have to take Remicade every 4 weeks. I was on the hook for about $6000. My bill was cut down because I qualified for charitable funds from my hospital.

It's shocking to see the bill before insurance pays it's share. I was getting bills for $25k. !!!

Why Implementing History and Philosophy in School Science Education Is a Challenge [pdf]
You were able to install Rockbox (an aftermarket ROM for Apple, Sansa, and a few other mp3 players). Was quite good, had better codec support (played OGG files!) and you could write apps [1] for it.

[1]. Don't know if you could call them apps, as they needed to be rebuilt with the OS (don't remember if they were pluggable modules or you literally had to rebuild the OS if you wanted to write an App, but it came out of the box with a few apps and games, and you could write your own in C. Their API was weaker than Android's, but to me more enjoyable.)
This is a great analysis. The lack of trust as a feature in cryptocurrency is really a bug in society.

Bitcoin rose out of the previous financial collapse by appealing to people who have lost trust in institutions. The problem with building a trustless answer to that problem is that (assertions ahead) life isn't compatible with an absence of trust.

Trying to build a trustless financial system is a quixotic undertaking at best. It really smacks of a utopian dream where fundamental aspects of human nature are blithely ignored.

Of course, as you point out, no one is really trying to do it. Most people will have to trust Coinbase or whichever exchange they choose.
You can second hand, try eBay or Amazon.

This criticism is unfair for many reasons:

1. Advising is teaching. In fact, advising is the majority component of an R1 teaching load! So, he DID discuss the teaching component of his job. A lot.

2. In terms of classroom teaching, he was probably teaching 1-2 courses per year at Harvard. So classroom teaching really wasn't the majority component of his job. It's unsurprising that he didn't spend much time talking about this minority component of his job, in the same way that it's unsurprising when a developer talks primarily about writing/reading/testing code rather than the ~20% of their workday activities that are something other than writing/reading/testing code.

Of course, one hopes that developers introspect on their effectiveness in various meetings, when talking to clients or internal stakeholders, and so on. But you'd be unsurprised if a dev, discussing their biggest mistakes during their first few years, focus on code-related mistakes.

3. Maybe he felt good about his non-advising, classroom teaching? The title of the post is "everything I did wrong", not "a summary of everything I did".

First question, no, they use CO2 lasers which emit in the um range, not nm. Probably a typo.

Second question, the loss of power is due to two factors:
1) Conversion efficiency of CO2 laser pulse to EUV light pulse. This is in the single digit range as a percentage.
2) Transmission loss of EUV from light source to wafer. EUV mirrors reflect in the ballpark of 50% of the light, and there are many of them inside the scanner, so you have .5 * .5 * .5...

Ask HN: How to negotiate salary as consultant in deep learning?
Dear all,

I am about to design a deep neural network for a small logistics company from Germany (about 10 employees).

It will be able to predict the best prices for courier deliveries the company mediates.

I don't have proof of experience, but I have references.

Now I have to negotiate my salary. I have never worked in this area before, therefore I am afraid I will not have a very strong position when I dont know what is a common price to ask for.

If somebody has experience here, it would help me to know if

1. I should ask for a hour-based salary or just name a price for the finished network (what is common?)

2. What hourly wage/price respectively is reasonable?

Thanks alot!
> By the time Microsoft caught up with WinXP and Windows Media Player

Windows XP pre-dates the iPod. Windows Media Player pre-dates the iPod by over ten years.

The real differentiation is charging speed; replacing the reactants is always going to be faster than running the reaction in reverse, so you are never going to get charging a traditional battery to be as fast as refuelling a fuel cell. Even “fast” chargers are going to continue to be slow (a Tesla supercharger takes over an hour for a full charge), making battery cars good for commuting, but bad for long-distance travel.

That doesn't mean that battery cars won't have a lasting place in the market: pure commuting cars that can afford long recharge times are likely to be a major chunk of the market. But they are unlikely to be the whole of the market, ever.

Sure, this is all correct from implementation perspective as levels are not strictly defined and are open to interpretation. However, we were talking about users' perspective, which is kind of the whole point of leaky abstractions. In this context language level features are those that users can understand about the language without any assumptions about other levels, like how compilers represent things internally.

> A lucky set of circumstances led to the iPod dominating the digital audio player market: bold marketing, a smaller HDD form factor, high-speed FireWire connection, and a great integration story on Macs.

Which of these four things are lucky circumstances and not the product of smart, consumer-thoughtful, hard work on the part of various teams at Apple?

Why is it that Apple has been "lucky" in this way so many times when so many other companies could have won instead?

> Apple had already stolen the higher end of the market

Stolen? I realize this is just a turn of phrase, but I think it does reveal a strong bias that sees a market win by Apple as illegitimate.
One, you're attributing something I never said, and two, my actual claim is not objectively false. Three, I don't have to do anything, much less prove what is otherwise easy to find out via Googling. And four, it's not irrational dislike, it's dislike based on personal experience and observation. Five, it should be pretty obvious exactly why i'm attacking Google, it doesn't need citing (unless the reader can't put two and two together, vis a vie "Google uses its privileged embargo status to disseminate sensitive information in a way that harms its competitors")

That's still no replacement for basic formal mathematics and linguistic skills, such as how to craft a good text.

I'm not denying Kerbal and Minecraft are stimulating for kids but no way can they replace the fundamentals. In the general sense. If we categorize kids time into 'education' and playtime ( both of which are important!) I would categorize minecraft and kerbal into the play section.

What reason do we have to think that will work, however?

Besides being more workable without pervasive internet access, hoarding USD / Euros have the very nice property of not risking retroactive deanonymization.

> Also, claiming that communists tried to nurture a middle class is just plain wrong. Communists were, at least according to Communists, trying to abolish class entirely, and initially to uplift the proletariat, the working class.

Precisely. And the Communists did one thing grossly wrong - they substituted the Capitalist class with the Communist "Elite". It was from an older owner to a newer owner. The people saw little difference in who they were required to work for.

A new Communist thought is that of worker collectives. The idea is that they are better than unions, with the capitalist class continually picking and clawing at any reforms. With a worker cooperative, the owners and managers are the very workers which eliminates that avenue of strife. And it is one step closer to the proletariat owning the means to production.
