Was editing 60k is teaching 4 classes with students paying 10k over 4 years. 90k for 6 classes but that's before expenses such as administration, the buildings etc.

It might be possible to nominally get that number but only if your hiding other costs.
I have to admit, I've had a lot of fun in the past thinking of creative ways to control botnets. It's a fun thought exercise in developing in an area where everything is adversarial to your goal. And the fact that the amount of information you really need to transfer is so trivially small that you can get some really creative "solutions".

My favorite idea so far is to look for the existence of a specific username across several services for commands. Only the usernames are (in part) generated via a TOTP style rolling code. So to see if something should activate, it will look for the existence of a username of "imnotabot349556" on reddit, HN, and twitter. if it sees any of them, it can read a small command from any number of places on those sites that the user can post some kind of comment/profile/text.

This is super easy to control securely (could be done from anywhere, using any machine, over TOR or other networks), is hard to shut down (the rolling codes mean they would need to either have access to the "secret" and ban all future codes, or just ban "imnotabot*" which wouldn't be sustainable if multiple botnets started using this method, not to mention you could just switch to a hash of everything as the username), and is fairly fullproof (no reliance on any one network or channel). And with some forethought, an update mechanism can be built into it as well, so when someone gets close to your scheme, you could have all your bots update at a moment's notice to a new one.

At the end of the day, trying to stop a C&C server of a botnet is a futile exercise. Once the botnet is out there, there's no stopping it by shutting down a C&C server. There are just SO many ways to pass information, and when the information is on the size of hundreds of bytes in some cases, there's just no hope.

Pretty much all of them realize that the speculative bubble is built on nothing.
I don't know if I'm making this up, but doesn't overengineering classically refer to the engineering practice of having wide safety margins or "unnecessarily" high performance?

Like, making the bridge twice as strong as it should need to be, or making the car faster than it's wise to go.

That's different from typical software overengineering, which usually doesn't make the product measurably better, just more complicated.
> What you're saying might be true if this were a perfect market, but there's externalities in that market (like liquidity) which you're not considering.

It is absurd to claim that liquidity in Uber shares would result in a 30% discount. A far better explanation is that preferred has rights that add most of that value.

> Fiction as it may be, it's the best instrument the public has to work out the value of a private company.

It's consistently wrong and in the same direction. As such, it's absurd to pretend that it shouldn't be discounted. It's fun for PR and headlines, but that's it.

The real summary here is that you, for whatever reason, are looking at a market transaction and claiming it's not the real market price. That's not just stupid, it's ludicrously arrogant of you.

You are essentially claiming that you are smarter and better informed than the participants in a large financial transaction. The rest of us are simply arguing that maybe we should trust the market a bit more, and be a bit less arrogant than you.
>Even being accused of something can easily ruin one's life, despite the "innocent until proven guilty" principle.

Did 16 women accusing Trump of sexual harassment ruin his life? Did it get them sued for slander? Did it even prevent him from being elected president? No, no, and no.

Yet Trump is still playing the victim: we are now to believe the Access Hollywood tape that Trump confessed to and apologized for is not only "locker room talk", but actually fake.

Poor Billy Bush is a victim for losing his job over something that never even happened, but Trump got elected in spite of confessing to and apologize for something he didn't even do, huh?
Rumor has it that he decided to take up writing as a hobby, which resulted in a movie script called "Rogue One."

Disclosure: PM of High-CPU Droplets @ DigitalOcean

I'd highly recommend people check out the performance of the High-CPU Droplets for any compute-bound tasks like CI/CD, batch processing or active front-end web servers.

Someone from our team put together a comparison of compute series machines which includes GCE and you can see the price-to-performance ratio here is pretty solid for DigitalOcean: https://imgur.com/a/o16t2
This rumor is so lame. Kinda like calling Musk “Tony Stark”. God I cringe just typing that.
Your opinion is just that your opinion. Everyone has one. As for Bitcoin and other cryptocurrencies - they are physical fact. When ideas and physical reality collide - ideas get smashed.
Do you think it’s a Good Thing when users lose all of their data to WannaCry or have their bank accounts emptied? I do not.

The vast majority of users simply do not benefit from being exposed to such complexity, it certainly shouldn’t be the default.
> Apparently not. Care to enlighten me? Because seriously, .1% of global electricity consumption, if that number is accurate, is expensive. Are we going to go up from there, or down, and how does it relate to a long-term stable bitcoin exchange rate, relative to mainstream reserve currencies?

The electricity cost of mining bitcoin is directly related to the transaction fees, once all bitcoins are mined. This is because if mining is very profitable (transaction fees >> electricity cost), more people are incentivised to mine, thus raising the hash rate and difficulty, thus making mining more expensive. If mining is very unprofitable (transaction fees << electricity cost), people turn off their machines, hashpower and electricity cost drop, and mining becomes easier.

Thus if successful BTC has ~300k on-chain transactions a day, transaction pays average $1 in transaction fees, you expect ~$300k of electricity to be used a day.

--

No one expects BTC to keep deflating 500% once it reaches saturation. Currently all of BTC value is speculative - based on the 0.1% change it'll become successful and be worth $MOON, against the 99.9% change it'll fail and be worth 0.

In the end-game scenario where it's an established global exchange network, with all the coins available already mined, it's only as deflationary as other currencies are inflationary.

The 'inflation causes investment' theory only applies to investment that has expected return of 1-2%; given that the stock market return is estimated at ~7%, and yet people still hold cash, it seems hard to believe that inflation has significant impact on investment.
I just switched to Android after being an iOS user since the iPhone 4. Honestly the fact that I have this stupid "Bixby" button on the side of the Note 8, almost perfectly in the middle, that I hit by accident maybe every third time I pick the phone up, is infuriating. No way to uninstall it, no way to turn it off, just a ~30% chance of launching some stupid app I don't want to use every time I pick the phone up.

I'm sure it will get better over time but I don't want to have to change the way I pick up my phone to avoid Samsung's garbageware.
The Making of Planet X2 for the Commodore 64
Yeah I've read that these "start" cars won't stop for security reasons.

Still a button less key .. with a distance based protocol .. I'm no expert but it sounds so naive.
So here is the problem.

The security of a Proof-of-Work network is proportional to the amount of work you put into it. You can call the work electricity or computation, but ultimately the work is money. And the money spent securing Bitcoin will be basically the mining rewards. Right now, at $10,000 / BTC, that's about $6.5 B / year (10k$ / BTC * 12.5 BTC / block * 144 blocks / day * 365 days / year).

If you want to maintain the current level of security on the Bitcoin blockchain, you need to continue to pump $6.5B / year into mining rewards. You could spend less, but then you get less security. Right now BTC is pumping that money in through inflation and investment in the currency through exchanges. If you wanted to put that money in through transaction fees, then you need to have $6.5B worth of transaction fees per year.

That is a lot.

VISA has a yearly revenue of $13B, and a lot of that is interest charges and bullshit fees, not transaction costs. Mastercard and Paypal have yearly revenues of $10B.

It's still not impossible. If Bitcoin processes a similar number of transactions to one of the major credit card companies at a similar fee level, that would probably work out. It would need to process significantly more transactions to make a lower fee work, and if it can't match the transaction volume, it needs a significantly higher fee.

If the fees are insufficient, the size and security of the Bitcoin network will fall to match. How much security are you comfortable with? $1B / year? $100M / year? $1M / year?
While the Ubuntu telemetry stuff is now opt-in, your point still stands. What you describe is exactly what Android has become.
Yes too I think "Upvote" and "Agree" are too similar.

Actually I've implemented a 4 votes discussion system:

- Like = I agree / useful / insightful

- Disagree — does not affect post sort order or karma

- Bury — for moving well-intended but boring comments, like "Thanks!" and "Me too", downwards. Without having to delete or actually downvote them.

- Unwanted — this corresponds to HN's downvote. Core members & staff can use it, if they don't want that type of comment, at the site. Reduces the commenter's karma, moves the post downwards.

Here are two demo pages: (scroll up a bit to see the "Some disagree with this" warning)

"Adobe Flash Player is required for interactive charts."
Thank you for mentioning that! I could not believe when I saw "my" Germany so close to the US, because for Germany, this number must include every little sailplane field and a lot must be missing from the US. What I really wondered about is the pattern by which airports have been included. Where 100% private airports not included (because the US has an immense number of privately owned airstrips)?
Even Flight Simulator X had about 20.000 airports worldwide ten years back. I also think that the USA have almost as many airports as the rest of the world combined. There are countries where private flying and airport building is virtually non-existent (take Iran for example) or heavily regulated (take Europe). So this database might be a starting point, but I wonder if there are no better databases available. May be: not for free.
It's not really the same game. Having something hidden in a firmware blob vs. installing crapware on a running OS. Thankfully there are cheap SoCs that can run blobless, like Allwinner H5, which runs the Xfce/firefox reasonably fast, and hopefully, this year it will get FLOSS video decoding support, and I'll be happy as a mouse. Mali free software drivers are also being actively worked on, but that's much less interesting.

Finaly a computer I fully control. :) Next, I'd like a tablet I fully control, without all the complexity of Android or traditional Linux desktop environments. Nice small userspace with small tablet GUI apps + HW access server, written in C. All snapping fast without a crazy-bloated SDK. Something that can start in 3-4 seconds including linux boot.
I still find it funny that people dare to call the Democratic People's Republic of Korea a dictatorship. Names are sound and smoke, as Goethe said.

At present day, SEPA SCT (no Inst) offers low to zero fee same-day transactions, Bitcoin transactions of the same fee will take longer (I had one stuck for a couple days at a 5ct fee this year)

@hackermailman - that site is a good tip thank you, I will look into it!

There are two reasons why I am (at least for now) looking for a regular job (even though I might have to take a big salary cut). Firstly, with my EU citizenship I can stay only 90 out of 180 days in Ukraine. And my one year Russian business visa has the same condition. So I cannot settle permanently. Secondly, I think working together with the (local) people will be one cultural part I want to experience and will help me to really integrate into the society.

Miners can't unilaterally fork Bitcoin without consensus in the community. They tried this already this year with Segwit2x.

Unless a critical mass of actual users want the fork, it will never succeed, because the fork will not have enough value to be worth mining.
Also, while the charts no longer require Flash, they no longer support arbitrary date ranges. So they're useless too now.

Also, I find it very disappointing that they removed portfolios and portfolio downloads without telling anybody in advance so that they could download their portfolios beforehand. (Edit: apparently https://finance.google.com/ is still available separately, for a short time)

No, seriously. We get that graphic artist you know create a slick image of a 'gold' coin, and then we can further confuse the rubes by telling them their 'coins' have to be "mined", as if they were real, physical metals!
Dude... you are insane! What kind of moron would buy something like that?

>Taking that into account, could a slow and steady rise not just become a system equilibrium and go on an on?

There's positive feedback inherent in the system under control. Specifically, lower volatility makes it safer and more profitable to use leverage. This leverage will force people to overreact to negative market movement.
That's nominally 50k/student they can then offer scholarships so it's possibly nobody actually pays that much.

Further, just having a teacher without a classroom is not going to get you very far. Still, assuming the average student pays 1/2 that much per year they can probably cut the costs significantly.
People are extraordinarily stupid. And selfish. And greedy. And all sorts of other bad things. Giving control to other people isn't any better.
I highly suggest reading the original book on Lucid. It completely changed my outlook on programming language design. Section 1.5 is also one of the more hilarious takes on programming culture I've come across, so if you don't read the whole thing, at least read through that little gem. A pdf of the book is linked elsewhere in this thread.
Oscillation happens in many complex systems - population sizes etc.

I think the reasons for why cycles happen in economies are many. It's probably desirable to reduce the amplitude of the cycles, but I'm not convinced humans are capable of that. Due to biological reasons, reward functions are almost always short term. Humans, as individuals and societies, are not very good at optimisations at longer time scales.

I'd like to think that we are capable of more, but it may be that we are not. AI (at some stage) might be able to help us there, if it turns out to have better predictive power than humans - and doesn't lead to more ruin rather than improvement in the human condition.

But that's an issue. I agree nobody really knows. But the believers at least have small holdings. Where as skeptics give reasons, which may be true, but only time will tell.

May be search for an Ethereum contract, which allows betting against Bitcoin. Solidity new hack discovery permitting, you can make a small killing. Would be nice way of making a point with some skin in the game.
You must also consider the cost of storing, moving and exchanging, and guaranteeing the currency. Printing on its own is useless.

> Not that loan-free educations are bad, but why is Brown raising $120M from alumni and the like, rather than lowering their tuition by $120M?

Because the Third Associate Dean of Humanities can't fund their $600k salary with the goodwill from a more reasonable tuition.

Snark aside, it's because the administrators are attacking a symptom - high tuition prices - and not the illness - administrative bloat and universities that are not run by academics, but by Professional Educators who in many cases have never taught a class in their lives, or haven't taught in the past n decades.

I think the main problem is that once something works it's marked as "Done" and won't get touched anymore. I often over-engineer massively until I really understand the problem and have something working. But then I try to simplify and delete as much as possible. It seems a lot of people skip the last step.

There's a lot of money in oil that will be captured by the 'free' energy of renewables. Renewables are just now becoming more cost effective than oil. Oil will be around for a long time but renewables are poised to overtake it in consumer and commercial energy. Might take a few decades but it's inevitable that a vastly more efficient energy source becomes the market leader.

Also, governments across the world are putting in place regulations to build and retrofit buildings to reduce emissions. That's not just energy, it's the actual building materials and techniques. That's a lot of government mandated money about to be put into green infrastructure. Again, this is over decades so the ramp time will seem slow to us humans but now is the time to get in IMO.

If mining becomes unprofitable, miners will stop mining and the total network hashrate will go down. The protocol will adjust by making mining easier, until it balances out at one block being mined every 10 min.

In a competitive market we should expect that mining costs (energy consumption) would converge to the mining reward, which is currently at 12.5 bitcoin per block. (I don't know how competitive mining really is at this moment though)

Of course, it is important to remember that if the mining difficulty becomes too low it gets cheaper to launch a 51% attack on the network.
Tuition is far lower if you're a Canadian citizen or resident. If you're foreign, it costs $25,000+ per year which isn't that different from public US universities.
