When we talk about the term 'computationally hard', we usually mean an NP-hard problem. I assume that here, 'memory-hard' means that no other hashing algorithm can have a greater lower bound on its memory complexity than Scrypt. Is that correct?

Edit: After a re-read, I realised that the answer is in the text:

"Memory-hard functions (MHFs) are hash algorithms whose evaluation cost is dominated by memory cost."

Ask HN: Should I learn TypeScript or advanced JavaScript?
I am working on JavaScript for years and I know it, but I still need to work on it, to know more design patterns or solve some problems that I have already. Alongside that, there is TypeScript project from Microsoft which Angular 2 used that! It means Google developers also trusted that. I don't know if should I improve my JavaScript skills or learn TypeScript? What are my limitations in TypeScript or JS?
Thanks. Yeah, let's say it's a choice that risks undervaluing the product ;-)

Also, diminishing returns apply: going from 0.25 fps to 40 fps is a game changer when doing interactive modelling, in the sense that only one of the two can be considered interactive. Going 40 fps to 4000 fps wouldn't really be make things much better (I'm sure artists would simply push the tools to bring that frame rate down again, and any improvement to render speed obviously would matter for final exports, but you get what I mean).

I'd like to second that, and mention that it's excellent to combine with "What the Dormouse Said" (John Markoff) and "Hackers: Heroes of the Computer Revolution" (Steven Levy).

Very loosely, while there is lots of overlap between the three, Markoff covers the West Coast more thoroughly, with more material around his idea that a lot of the development there owes a great deal to LSD...

Levy covers the East Coast more thoroughly, going into a lot of detail about MIT, and the environment around the MIT AI Lab.

While Waldrop both goes further back, and takes a higher level view of the politics and DARPA itself.

There are of course plenty of other pieces to branch off into once you get to the rise of home computing in particular, but the above three books combine to give an even more fascinating picture of the early days of computing than they do separately. And BBN of course still stands out as one of the highly important pieces.

BBN is one of those companies that are fascinating to me, because like e.g. DEC, when I first got online in '93, they were the type of legendary that you when you are young take note of the status of, but don't really know the significance of, until you get a bit older and start being interested in the history of what you've built your career on...

For my personal computer I use Microsoft Security Essentials / Windows Defender. My biggest threat is when my kid is using my computer and playing on some flash game websites, so all my user accounts are currently non-administrators which atleast might mitigate some attempts.

However, at work it's a different picture. We have 300 "lusers" and everyone are eager to click on the newest malware on the block with no thought of consequences.

We've tried several AV products and right now we're using BitDefender which seems to get the work done for the most parts. First time we ran it, It found our (IT dep) 10 year old Red Alert 2 .exe crack so that was quite amusing. It also has few false positives and hardly ever makes itself noticeable in resource monitor.

> In Portugal, it seems to be coming from the rental market. In the sense that there's been an increase in tourism and the increased demand for short-term accommodation is being fulfilled with properties which were previously for longer rentals.

Procedural generation still depends on how many game elements are designed by hand. If you have X game elements and add a layer of random noise, given enough measurements you will arrive back at X game elements. It's kind of like adding a random delay to an algorithm that is vulnerable to timing side-channel attacks.
You should bring that to the attention of the developers.
As a reminder, on a larger scale: Apple's main focus is on design. Not build quality [0]. This doesn't exclude a unique production process of course. But I think it is important to not mix up both when forming an opinion about them.

Because it means that the amount of free time people have (for mental or physical relaxation, spending with loved ones, personal [non-employment-related] study) depends on how easily you can part with some of your money. If you believe, as I do, that the amount of wealth people enjoy is in many cases a result of luck -- luck in who raised you and where, luck in the stock market, luck in genetics -- then it starts to seem wrong to distribute "time" in exchange for money.

> "during periods of economic uncertainty way worse than today. Such as the period from 1982 till 2006"

The bulk of the period you mention is referred to as Great Moderation by high fiving central bankers. It’s part of one of the great green areas on the chart of the original post. It was marked by disinflation, fall of the Iron Curtain, corporate adoption of computers, globalization, trade and offshoring. (And rising central banker activism and financialization.) And yes, gold went through a gruelling secular bear market during the Great Moderation.

Conversely, all big red areas on the chart saw positive action in gold.

In the 1930s-1940s large quantities of gold were being hoarded. The official price of gold itself was fixed but e.g. gold mines did great.

In 1960s gold was being hoarded again, to the extent that by 1971 they had to give up the fixed price and let it float.

Since 2000 gold has being doing great again (with corrections in 2008 and a bigger one since 2011). Interestingly enough, the latest correction seems to have reversed the exact day Yellen decided to hike rates with 0.25%.

Imagine you could reconstruct a performance chart for gold, similar to the S&P chart of the original post. I’m fairly sure it would be roughly inverse to the original S&P chart.

(In practice it’s hard to really do this, because the gold price was fixed until 1971. So before 1971 you’d need to reconstruct perhaps some kind of measure of “stress” on the price fix, or use an imperfect proxy such as gold mines.)

> "There are plenty of growing sectors and there will continue to be."

True. But in some eras an investor can make a 1000 mistakes and still expect a good outcome. In other times there’s much less room for mistakes in terms of timing and securities picking. Things are harder, like really much harder. The difference is caused by general valuation levels, the kind of profits that are being priced in, and by the amount of eyes that are looking at the same things.

That's just a different formulation of the exact same message the original chart is telling us.

The last great investment desert ended ~35 years ago. Once again, around the time when people where lining up to buy gold. Crawling out of that desert, if you thought you had found a bargain on the stock market, a real gem of mispricing, chances were good that it actually was a bargain.

In my humble opinion, we're somewhere deep inside another investment desert. This one appears to have longer lasting and more elaborate fata morgana's than before. But I expect we will witness a few serious extinction events before we can even think about crawling out.

I think the another issue with most of these "for kids" environments is that they have low ceilings of mastery. You know, like the "low barrier to entry, high ceiling" principle of Smalltalk? Usually because of some misguided desire to shelter them and keep them safe.

Also, I started out on DOS at the age of six, with the left-over computer my parents had after they upgraded the server at work. It had two hard drives of a whopping 40mb! Anyway, the neighbours next door had a slightly older son who explained to me how cd, copy, mkdir, del, etc. worked and he gave me a bunch of games via floppy disks. I didn't understand everything (this was before I spoke English, so no idea what the "park" command referred to or why it was important), nor knew why everything worked, or understood why some games didn't quite work when copied to the hard drive (because I didn't copy the sub folders) but I managed. Wanting to play games is a good motivator to learn any interface.

Based on Sugata Mitra's experiments, I'd say as an individual I wasn't exceptional in any way; give a group of kids a computer without an artificially low ceiling and watch them go! The circumstances I was in might have been unusual at the time, but that's different.

How does making rare item combinations available based on willingness to grind them out become intellectually complex? The original Star Wars MMO had some cool crafting mechanics, but I don't know enough about them to really explain.

Eve Online has emergent gameplay but most of that is space politics and metagaming - almost despite the game itself rather than because of it.

Heck, vanilla minecraft has incredibly complex outcomes from basic rules - vis a vis redstone and automation and so on.

I've played hella grindy Korean MMOs, they were just a case of spend x time get y thing. No real challenge, just a willingness to keep trying until complete. I'd strongly suggest highly complex systems restrict player innovation and emergence, in a way simpler rulesets do not.

Does it never do DNS lookups? Open files? Do you not want to tie into process management? Logging? Do you really have no dependencies on a functioning locale? Network settings? Are you sure it won't try to exec anything?

An application with no other dependencies is exceedingly rare. Small tools, sure. Sometimes. But even then I see people making silly assumptions all the time, which makes using a container as a suitable straightjacket very useful.

E.g. I run all kinds of tools "with no other dependencies" all the time, that turns out to have all kinds of dependencies when you actually try to put it in the smallest container possible.
I agree with most of what is said here. What has personally helped me is to know the limits of patience and to walk out of the scenario as soon as those limits cross. In the quoted instance, I would have never waited for 35 minutes on the call . I would have cut the call in 10 regardless of the expected outcome.

It's better to judge what kind of a situation you are walking into and set expectations accordingly. For instance, in Bangalore I know that it is normal for people to be late for meetings. Traffic is bad, your previous meetings don't end on time etc. So I'll be prepared for a 15-30 minute wait. Beyond that I'll just cancel and move on. I failed do this on an interview and it was just an unpleasant experience. The interviewer was pissed and so was I. We just wasted the next 30 minutes.

I see where you're going, and I like the general direction, but I won't agree with "No? -> You are wrong."

A major strength of human society is its diversity and individual specialization. Everyone needs a different job, so that all jobs get done. If I imagine a work where everyone does the same job, it will result in mayhem because other important jobs don't get done. But that doesn't mean that every job is wrong.

Finally an article that answers some pressing societal questions:

* Can hostfully.com identify suspicious data analysis? (no.)

* If given the chance, will Airbnb present misleading data for self-serving ends? (yes.)

* Will an already self-serving study be given an even more self-serving spin when presented by a sympathetic reporter? (yes.)

To understand what I'm talking about, consider the source cited by OP (http://hotelnewsnow.com/Articles/77191/New-Airbnb-data-sheds...). Going by that data we might be tempted to say that Airbnb is being out-competed by the hotel industry.

However, stagnant growth on the part of AirBnb seems like it would have been widely reported. And yet it hasn't. Googling we find a seemingly contradictory datapoint: Airbnb's revenue is up 89% this year (http://www.bizjournals.com/sanfrancisco/news/2016/09/01/airb...).

How can Airbnb's revenue have almost doubled while still losing market share across the board?

Option 1. They didn't lose market share across the board, and instead cherry picked non-representative markets for their 13 region hotel comparison.

Option 2. They lost large numbers of low-margin bookings across the board, while gaining (taking market share from hotels) higher margin bookings. [Note this would contradict OP's article.]

In both cases, Airbnb's data is misleading.

Learning how to draw #11 – The Wave
Most of the anger I experience or come across from others is borne out of selfishness. The article makes a good point. Controlling anger is usually in our best self interest - thereby being a means of tempering our selfishness for long or short term benefit.

It points to something else which is not discussed as much: Self control. The amount of times I've seen grown adults and over 60s acting like petulant children over the most minor inconvenience. I cant help but think that in the span of your life you have not yet learnt to control your emotions.

Some comments refer to buddhism. Which to me is a form of self control.

Some other comments, point out rightly (imo) that Anger like all emotions serves a purpose and should not simply be ignored. I think the purpose of anger is to highlight (but not validate) the differences between our expectations and reality.

In order to assess the balance between our expecations and reality, you need self control, I think. Otherwise you can act out of haste.

The goal would be to reduce the space of the attempted guess. I don't see how it would be a practical attack though.

booking.com is one of the worst things currently for owners - they are ridiculously backwardish, all processes takes weeks/months instead of hours like with airbnb, super expensive and on top of that, they don't even facilitate payments - so you either ask people to bring a lot of cash, or somehow obtain credit card reader (and go through all the hassle that comes with it, which I won't).

to sum it up, I do believe and hope booking.com will slowly die, since other services are just better in every single aspect.
