What everyone else said, but if you want a "quick and dirty" way of doing it, you can just use a simple genetic algorithm:

- Start with a couple (say 100) completely random schedules

- Measure how good they are via a fitness function (say, start at 0 and everytime a constraint is violated add 1 point. You can be fancy and add different amounts depending on the type of constraint violated)

- Sort the schedules from lowest to highest

- Pick the top 20 or so

- Generate other 80 schedules by mutating the 20 you selected before, randomly shuffling the talks, and possibly mixing up different schedules together (crossover).

- Repeat for a couple thousands of generations, the population should quickly evolve towards better schedules

- You might get stuck on local minima, but for the most part you can just run it again several times from the start and it eventually won't get stuck

- Not guaranteed to give optimum results but should give decent enough results

I suppose that is true, but if the price does crash back down to $1,000 and then rises up to $6,000 then what does that mean? The bubble burst and the price crashed, but now we are in another bubble?

This article is an interesting read and seems to suggest something like that:

> piracy as a threat to their revenue streams, hence "competition"

By your logic, I can "compete" with GM by stealing all of their car inventory and blowing up all their factories in Detroit. I don't think that makes sense.

> the market has simply changed

Strongly disagree. What exactly is the new market? Selling journal t-shirts?

> yet the peer review process relies on unpaid volunteers

> Publication bias is a thing

I say that publishers add much more value than pirates. Sure, publishers aren't perfect and others add value too. So what?
Electricity cost per mile driven is not falling. Electricity costs per kWh go up slightly every year, I've never seen that cost go down (though it also varies widely across providers, and even time of day). EV's are also not really getting more efficient, if anything efficiency is going down a little as batteries get larger and people don't have to obsess about squeezing range out of the car (I see a lot of Teslas cruising in the left lane at 85 mph).

Net-net, electricity cost per mile driven is going up, but is still significantly lower than for gasoline in most locales.
How is that any different from issuing shares privately to VCs? It seems to me the only fundamental difference is with the technology. Things like voting and vesting can be done on a blockchain, so that's not a limitation. There isn't any rule that says a blockchains token distribution has to be "fair". Granted, a more "even" initial distribution makes sense for a currency, but it you're treating crypto tokens as shares in a company, those "rules" need not apply.
What if, when you replaced your SSN, banks could use a system that would return "invalid SSN" on any new credit application. The existing accounts would be suspended unless you called them and updated your SSN. It would be about as much as a hassle as updating all of one's autopays when a credit card number gets stolen.
Every back is different, your mileage may vary. I hurt my back to the point I couldn't take a running step for 3 years. Serious lower back spasms for a year at least. If you've messed with the cartilage/disks of your vertibrae you're looking at at least a year of gentle recovery.

Now I can sit all day (and run) but I need a chair with a seat plate that can tilt forward (basically pelvic tilt while sitting).

If you're new to back injury the most important thing that they don't tell you is: the damage you do today to your back won't be evident until tomorrow. The feed back loop is way too slow.

In my experience, the best treatment for lower back pain is (once the cartilage is repaired) to walk, no matter how bent over you are, walk and walk some more.

I think the stretching etc can be helpful too but I haven't tried that. I'm just very careful about how I use my back when I'm bending over.
As a Brazilian-American who spent many years in both countries from the 1980s until today, you're misrepresenting things a bit.

First of all, the juice concentrates are a newish thing, 20 years ago it was still common to make fruit juice from scratch at home every day. Also, farofa is fried (more like sauteed, it doesn't need that much oil) yucca flour, which is a world away from refined white flour. Growing up, lunch was a large salad along with rice, beans, a cooked vegetable and some kind of meat or fish.

I fully admit that Brazil really took to fast food and it's just as terrible as it is anywhere, but your analysis of "traditional" Brazilian food is quite myopic and probably influenced by your own white-collar professional tendencies towards convenience foods.
Interesting - what differentiates workstation-class machines like these from dedicated server hardware? They're marketed differently, right?
Taleb has a similar message The Black Swan. There is very low risk to making wrong predictions and a ton of upside if one is right.
I have great respect for Kevin Roose, but this was a disappointing piece. Dogecoin was a meme. It gained popularity and is still worth something. Jackson Palmer might not believe it has value, but clearly, there are people who own Doge that think otherwise.

There is definite frothiness in the market. Some token sales are scams, some are overpromising, and some that look promising will probably blow up. Take a look at SEC Fraud statistics for 2016. Crypto scams are a small fraction of these crimes: https://www.sec.gov/news/pressrelease/2016-212.html

Reporters need to separate Bitcoin, Ethereum, Litecoin (and some of the other older cryptocurrencies) from token sales and other crypto assets. Bitcoin has existed for 9 years and has real users with real use cases (remittance & cross-border payments)

I can keep going, but reporters really need to make an effort to do more research and separate fact from fiction (I guess this can be said for many areas of journalism though).
That photo from 1978 is quite possibly the most explicit portrait of nerdom ever. It makes Comicon look like a frat party. I have never seen anything so completely nerdy.
> It is worth nothing that JP Morgan bought up millions of dollars worth of Bitcoin after the price crashed following that statement

The crash was mostly independent of Dimon's statements.
That sounds familiar to the various voting systems that satisfy the Condorcet criterion (basically, ignoring all votes for other parties, do people prefer A to B?). There are a lot of different ways of picking a winner when two or more candidates are tied under Condorcet -- ranked pairs, beat paths, etc, including rules like the one you suggest.

But in voting systems, Arrow's Theorem says none of those methods can be truly satisfactory, at least if you accept Arrow's list of requirements.

Similarly for Olympics ranking, I don't think any method for breaking ties will be able to satisfy all the requirements of a good ranking (e.g., removing a country from competition shouldn't change any other rank orderings).

So personally I don't think any of those tie-breaking methods really have any meaning. You might as well just toss a coin.

This is an impressively bad idea. Good work.
That's a great point. All three schools I attended growing up were designed like that. The school district spent a lot of money on separating the rooms out again. Climate control never worked after that.

It would be a shame for Apple to divide up the pretty space with ugly cubicle walls.
I dunno. Perhaps living the default life is better than switching to a belief system where you think it is appropriate to call for the murder of a man who had the audacity to write a book.
Various results are discussed in the Google Groups postings that are linked from the repo.
I love this idea of Huffman coding the syntax- I've been thinking recently it wouldn't be difficult to crawl all the packages of NPM for example, encode them into their AST's, and use algorithms to analyse them. e.g. trying to apply PageRank to visualise the most important classes/methods in a codebase.
The NY Times recently restructured their reporting operations in a way that reduced the amount of fact-checking done[1]. FWIW I'm a daily reader and definitely feel the quality has suffered.

Again, what number are you looking at to call California wealthy? California state budget revenues are $4,366 per capita, which is fairly low-end. North Dakota, Wyoming, Washington, Kentucky, Minnesota and Oregon are all in solid five digits a head. California's is richer than Georgia's $2,320 per capita for sure, but if it were a person in a company of 49 other friends, it would be a low-income friend always trying to borrow money.
License Zero [https://licensezero.com] is working on a means of doing this. I believe they are starting with NPM modules first.

As technologists, let's not overlook Thoreau's tech work [0] -
he made the lead pencil into a profitable product in the US:
and could be said to have invented the "Number 2 lead pencil"
in that the technique of blending graphite and clay made
it possible for his family's company to produce different
grades of pencils.

To be fair, European pencil-makers were using a similar
process as a trade secret at the time, and the market share
of Thoreau pencils was helped by high tariffs. Still,
HDT was not just a dreamer and writer in the woods, but
a technologist improving the very tools he wrote with.

Indeed, just like drug pushers.
> At one meeting, a representative from the food industry accused Anvisa of trying to subvert parental authority, saying mothers had the right to decide what to feed their children, recalled Vanessa Schottz, a nutrition advocate.

The same argument is used in the US to thwart limitations on sugary beverage purchases and other junk food with SNAP -- these compose 10-20% of purchases, 50% of which goes to Wal-Mart, alongside 2-5x greater premature mortality from cardiac arrest and diabetic related complications.

Incentivizing the poor to hock Nestle timed according to Brazilian food assistance checks is clever. Reminds me of Herbalife, and Betting on Zero -- Hispanic populations, eager to succeed in entrepreneurship, here too are victims of pyramid schemes preying on ill health.
Jikes RVM was known as Jalapeño first, then they changed the name to Jikes RVM due to a name clash (Jikes Java compiler already existing at the time). I'm not sure it is still active though, a lot of researchers left IBM a few years ago (2012) and Java ceased to be the hot topic anyways.
M5 Crash Leaves 4 Dead
One of the few instances where American Banking still being in the 1990s is a benefit[1] .. but not really.

Australia, NZ, Singapore, most EU countries all have instant person-to-person transfers with little to no fees and supported via the government. 500 euro can be gone like that. Poof. But it's all within the same country. And when it's within the same country, it's traceable, reversible and enforceable by law.

So the 1-3 business days isn't where the protection is at. It's the way we mark and track transactions. The real danger, is SWIFT transfers. Once that money leaves the country, it's very unlikely you'll ever see it again.

I do not personally believe the bitcoin markets will function properly for the shorting mechanism to pay off in interesting scenarios.

If I borrow your bitcoins, how will you force me to sell them? If we agree that a third party will warehouse those coins, how can I trust them? And if BTC plunges, who's to say that 3rd party will still operate?

All very different from shorting a stock.

But if you want to loan me your bitcoins, let's talk!

I'm also interested in borrowing any other bearer instrument that you possess? (Now thinking of bearer bonds in the movie Heat)

Coins could be useful for many ends, some dubious and some benign. Criminal purchases, inflation hedging, remittances, tax avoidance, online transactions, payments between friends, store of value / speculation. Any one of these could be affecting its value.

I often wonder though if Cryptocurrency's killer app is just capital flight from China, with every other use case just so much noise.

While that toy theory may seem reductive, it's miles more explanatory than the models offered by either the 'bubble' or 'will soon replace global financial system' camps.

Well, you could certainly draw that conclusion and make that argument, but I like to think of it as investing in the internet vs. investing in pets.com during the dot-com bubble.

As of right now, you are right. The entire crypto market is speculative. I think a platform like Ethereum has a better chance of being valuable than a random token that someone with no blockchain experience put together a whitepaper for in a few days and then launched an ICO for.
Neat. I do a lot of RF simulations. Even though it's 60 Hz vs 60 GHz, I suppose a massive electrical grid has the same distributed effects that can cause standing waves and stability issues.
So, how does this compare to ohai (from Chef) and mcollective (from Puppet)?

Is there a packaged version for other OSes, or is this Red Hat/rpm only?
You argue that publishing does not need to be as expensive as $2000. Fair enough. I would be happy if we can agree that publishers do something, and that piracy is not an alternative. That point seems to be lost on the majority of commenters here.
What is in a typical Brazilian breakfast in you opinion?
The real "value" in cryptocurrency IMO is public-key encryption, which everyone on the internet already uses every day for free.

The blockchain idea is novel, but I think way less valuable than the hype has led us to believe.

Do you have any stats on the percentage of traditional financial crimes that go unsolved vs the percentage of crypto-currency crimes that go unsolved? You would have a hard time finding a major crypto-currency heist, dark market, or rogue exchange that hasn't been tracked down and shut down.

I have multiple personal stories in which cabbies and cab companies (based in San Francisco and Austin, TX) colluded to defraud me out of hundreds and hundreds of dollars. I have told these stories too many times to get any catharsis out of repeating them here — but I am confident, and experience confirms, that similar scenarios would never play out with Lyft or Uber. An individual driver may be a cheat, not for long, and without Lyft/Uber covering for them (unlike Yellow Cab)

I am sure there are regions where taxi companies don’t completely suck. My very limited experiences w/ cabs in the South of France was markedly better than with taxis in Texas and San Francisco, for example.
Are you a super predictor?
I really like that you could volunteer rather than being commanded to do CS. Irrational as it may be that would make a huge difference for me. I'd personally consider volunteering but for some reason I'd resent being ordered to do it.
From the reading I've done on the subject and observing our almost 3 year old, the ipad gives a dopamine rush to the brain. Taking it away causes the dopamine to stop and anger/frustration ensues...

At most he's allowed 1 hour a day, half hour after breakfast and a half hour before dinner. Both times he's given a 5 minute warning to turn it off, then he has to turn it off himself. We learned this the hard way, plus a lot if reading to figure out why he got so angry and frustrated when we turned it off.

Nowadays, either we play with him and his toys or he gets bored with that and wants the iPad again. We tell him the times he can watch it and he goes off bored again and starts getting creative with play on his own. The dopamine thing (self made opiate) really opened our eyes to his behaviour when the iPad was taken away.
I thought the same thing. I like it, but my company's IT director will never allow it. Maybe they want to target the startups and couldn't care less about the old school companies...no idea.
Libraries only lend out the copies that they have purchased or access that they have subscribed to as previously mentioned. Libraries are a public good since they serve as a home for the local community and a benevolent institution for those who are very disadvantaged and might not even have access to the internet.

Yeah I should have made that clear. The price had already started a correction, and the crashing was more associated with uncertainty related to Bitcoin exchanges in China shutting down, but his statement certainly didn’t help. It was picked up by pretty much every news outlet.
Maybe. With a bunk front fan on my z820, everything still runs relatively cool at maybe a max of ~55C (2 CPUs, 3 GPUs, 16 sticks of RAM) according to sensors util in RHEL.
60gb for AAA games isn't that uncommon. If you never uninstall any games, you're going to notice that 1tb isn't much.

Sure, the stat has some information content.

To me, it's like saying "cell phones are getting more expensive, but cost/battery-life is improving!

Do people care about battery life? Absolutely! But I guarantee they care much more about purchase price, resale value and generally total cost of ownership.

If the car's price went up 2x, but the car's range went up 3x, I don't think you'd see celebration in the streets. That's why the metric is preposterous.
Hard drives back then actually had capacities in binary megabytes, and often even slightly more. The "10MB" HDD in the first PCs held 10653696 bytes, and the "5MB" one 5326848 bytes.
Only because it needs the battery to do the litany of other things it does. As for your "or it senses a heart rate reading that's greater" question... that comes from my actual use of the watch. I sometimes forget to put the watch into Workout mode. If I go into the Health app afterwards, I can see that the frequency of measurement goes up when the watch detects that my heart rate is above my resting heart rate. It goes from being sporadic to being continuous until it detects it go back down. So it's not that it can't do it, it just doesn't do it to conserve battery life. The Fitbits don't really have much else going on that requires the battery so they can run continuously all day. Additionally, according to most medical uses and reviews of the Apple Watch, it's more accurate than many stand-alone heart rate monitors so, as battery life improves, the watch can only go up from here.
Security reviews. Powerful enough to run multiple VMs to simulate caching server, web server, app server, and database tier while simultaneously recording and as necessary tampering with all network communications while running static and dynamic code inspection tools across multiple VMs. Load it up with some high-end GPUs as well for hash cracking. Memory is a big deal as well. I work with some programs that if you are running anything under 64 GB of RAM you could be waiting all day for results and 256 GB is preferred but can still be sketchy as that may not leave enough for VMs. If you are a researcher doing fuzzing, again, this sort of power is key to reduce a fuzzing run from maybe a month or two on a a high-end laptop to a few minutes.

Running inadequate machines waste time of otherwise expensive engineers. The other day I was giving a live demo of an interception proxy and accidentally clicked on a very large HTTP response. The machine I was using only had 32 GB of RAM so I had to open task manager and kill the app so I could re-start it because the meeting would have been over by the time it loaded due to disk caching.

I was a longtime ethereum sceptic, however I was guilty of being a cynical old curmudgeon; the type that poo-poo's anything and everything novel on the grounds that I'll be right 95% of time, ignoring the fact that I'll poo-poo everything that will ever change the world.

Bitcoin made currency decentralised and permissionless.

Ethereum has made capital raising and equity holding decentralised and permissionless. Sure, lots of people talk about SEC compliance, but in reality anyone can raise equity for anything now. You can issue a token to fund for a drugmarket if you wish, and pay dividends, and noone can stop you really. The market cap of ethereum is 22 billion.. is that to high or too low for the promise of permissionless securities?
