> So you also need to create heuristics, on how do you discard received data, until you get to a point where you can understand the stream again, and continue processing.

This can be trivially easy for some data formats, where you know the absolute or relative offset of everything. E.g. here is a chunk of data I don't care about: 32 bit length followed by that many bytes. Read the length, then hit the llseek system call (that would be supported on sockets just for this feature) to skip the stream position that many bytes ahead. Done.

I just read that review, and it's been years since I've read the book, but here are my thoughts on what I see as the substantive points in the critique:

1. Climate change: Ridley calls himself a "luke-warmer". He doesn't deny that a doubling of carbon dioxide causes a 1 degree celsius increase in temperature, but he accumulates various evidence in the book suggesting that estimated feedback effects (water vapor, etc.) are in excess of what's likely. This claim certainly falls into one of the debatable aspects of the book and I'm not an expert to really evaluate it. I think it's a valid criticism that Ridley is excessively optimistic on existential risks. My guess is that he has a Bayesian prior that dooms-dayers are more likely to be wrong than not. He has many examples in the book of experts predicting existential risks in history and being wrong, and I think this colors his view of all experts. I think those historical examples of wrong doomsdayers is an interesting and important perspective.

2. Societal Collapse: I believe Ridley wrote about how the black plague may have been an important catalyst in igniting the renaissaince, so I don't remember him making teleological arguments. I don't think Ridley ever claimed that there won't be problems or collapse, but simply that if you look at the aggregate statistics, humans have been improving dramatically in the last few thousand years, largely driven by new forms of energy in the last few hundred years.

3. Materialism: I don't understand this critique. I already see evidence of movements forming to help people find more meaningful lives: the scientific field of Positive Psychology and Meaning-in-life research by professors such as Dr. Steger, The School of Life, etc.

Bingo; that precisely the context in which I first saw the technique of 'fake ACKS' described: as a congestion-control-defeating mechanism which provokes senders into sending faster.
That's true, but I don't recall any indication of them faking ticker data.
Just responded with a separate reply on the critique. I agree we have to be careful with excessive optimism.

> In that Empire, the Art of Cartography attained such Perfection that the map of a single Province occupied the entirety of a City, and the map of the Empire, the entirety of a Province. In time, those Unconscionable Maps no longer satisfied, and the Cartographers Guilds struck a Map of the Empire whose size was that of the Empire, and which coincided point for point with it. The following Generations, who were not so fond of the Study of Cartography as their Forebears had been, saw that that vast map was Useless, and not without some Pitilessness was it, that they delivered it up to the Inclemencies of Sun and Winters. In the Deserts of the West, still today, there are Tattered Ruins of that Map, inhabited by Animals and Beggars; in all the Land there is no other Relic of the Disciplines of Geography.

A Mathematician's Lament, by Paul Lockhart. Also, i'm not completely sure about this, because i had to have my eyes a bit open to understand it. But would be nice to had readed it in my sixteens.

Basically, one of the important ideas i saved was; If you want to learn something, don't just simply study. First, find a problem that care you, then try to solve it, last, study how to actually solve it, maybe existed a better way that you could use for your next try, making easier to you to understand everything related to that problem and say with confidence you learned; maybe didn't existed a better way, and you can share and discuss your solution achieving a better one.

Find problems, solve them, make them easier, learn.

Then, make that general for all your life problems, not only those science related ones.

> For that matter, it's possible for the receiver to claim to have received a packet that the sender had not yet generated. The sending TCP stack may very well consider this an error.

The article deals with this head on: that's the essence of the ambiguity of "I have received up to X" versus "I am not interested in bytes up to X". The second intent is consistent with not having received bytes up to X, which is consistent with them not having been sent yet at all.

The anti-congestion-control situation is when the receiver is in fact interested in getting all the bytes, and so "I am not interested in bytes up to X" is of course a lie. But so is "I have received up to X".

Messenger apps, more than anything are screaming out for decentralisation. I'm not sure what the solution is - none of the major clients operate outside of a centralised model yet - and it's incredibly difficult to counteract the hive effect when it comes to these kinds of services.

This is a society level agreement I am absolutely baffled by. Most people can't or at least not well and there are not studies I know into this. Reflexes, decision making processes etc are all lacking in case something bad happens.

ECMAScript 2018: final feature set
I remember hearing about a study where they placed placards on top of cabinets and such in the operating room. When a person said they had a near-death experience during surgery and saw themselves from above, the experimenters asked them what the letter was on the placard. Not surprisingly patients didn't know.
The postulation of a limitation is basically a negative claim. "This can go only so far and no farther." Very hard to prove, and inherently myopic. Even if the observations are true, it's likely just a lull in the self-driving scene.

It's reminiscent of how some people once believed that a machine will never beat the top human players in chess.
Yes that is true, logistical support and processing have considerable costs. For aerial LiDAR collection via helicopter you're looking at about $20,000 per day of onsite collection including the helicopter team, insurance, and support. That gets you high density low altitude assets, not including the processing and storage costs.

It's cheaper to fly with a fixed wing aircraft, but you will typically get lower density assets and the possibility of obscured imagery due to cloud coverage because of the higher collection altitude. However the advantage is you're able to cover a wider collection swath with each pass, and it's a lot easier to fly a fixed wing vs. helicopter so the pilots are cheaper.
>Is war really about scarcity of resources or about conflict over resources, regardless of scarcity?

I think there is a huge difference between the world before the green revolution and after, and I personally think that this difference is a big part of why we haven't seen major power wars after the middle of the 20th century.

World war two was the last major power war, and it was also the last major power war fought when there were not enough calories for everyone to eat their fill. Coincidence?

After world war two (well, after the 'green revolution' that happened in the mid 20th century) there was enough food, and... you could argue that we haven't had a direct major power war since then.

I personally think that the fact that getting enough calories is generally not a problem anymore has a lot to do with the fact that we haven't seen any major power wars lately.

"Don't Make Me Think" by Steve Krug, Second Edition

The book changed the course of my life. It allowed me to build a sustainable business, that at some point became my full-time job.

The magic of that book comes from the fact that it allows you to gradually develop a compassion. For your customers, prospects and all other living beings in this world.

Having that compassion embedded, you start to see a lot of subtle things. The most impactful experience for me was to comprehend that the world is a place full of pain and hardships. Not only for me, but for all others too.

Once you see it, you immediately understand there is plenty of space where you can bring the value to others.

But that's not all. The story does not end there. It turns out that bringing the value to others brings value to you.

People start to write you things like: "you are legend", "if you ever come to Chicago give me a call", "here take my money". And this is a tipping point where things start to work as a good business. It starts to shape your life. At some point it becomes evident that you should charge a prime for your product and develop the whole thing even further. While helping other living beings along the way.

That's an awesome position to be in. I thank Steve Krug, the author of the book, for bringing his findings to other people like me.

How well could you, human, vacuum a house if all you were given was a Roomba robot's chassis controlled by you via joystick, and maybe a camera mounted in the robot?

There is a physical challenge arising from the form factor, such that your intelligence won't help. Those robots don't do stairs and tight places very well simply because the hardware is that way.

In driving, the robot has the same controls as the human. It can turn the wheels, brake, apply gas. That basic playing field is level.

It's all about how well you make the AI see and understand, and translate that into turning the wheel, changing forward/reverse, and hitting gas/brakes.
Hacker News Community, 4 out of 8 comments as it stand is basically a longer version of "Stephen Wolfram is a narcissist".

Obviously not every strategy will be sign independent, but you can design strategies to be that way.
Yes, but there are easier ways to make money trading volatility than forecasting single asset volatility. While you can fairly easily forecast volatility with R^2 higher than 60% for most assets vs 5-7% for the best models for returns, that's not the important bit. The important bit is whether you are better than the rest of the market. I would argue that implied volatility is harder to trade off a forecast than straight return because a greater proportion of the participants in the vol market are professionals, and also more likely to be highly quantitative geeks. Also my comment wasn't about being able to forecast large moves but being able to determine how much a news item was going to move an asset. As far as handling important news events and getting out of the way is concerned, options market participants are very good at it and have been for a while.

You need to do a full blood analysis. I'm not a doctor, but I know that testosterone can be bound to SHGB hormones and then it's useless for the body. But your total amount of testosterone can still be high, in range and so on but if a large % of that is bound to SHGB it's no different from having an under range level. You'll still feel miserable, having a more negative view of everything and increased risk of cardiac problems.

So check your amount of free testosterone and % bound to SHGB. Also, levels mean nothing if the balance between testosterone and estradiol("e2") is bad.

Yeah. To be more clear, you can install a "minimal" system of Ubuntu on bare metal by just installing the "required" packages only, although I think the default if you don't select any tasks in the installer is to install "required" + "standard", which is a small amount more than just "required". Either way, it doesn't include much. I have to install openssh-server on my "nothing-but-standard" systems, before chef comes in and drags along another 1000 packages.

The installs the OP is talking about are images that don't even have a kernel, and don't use the traditional installer.
It's pretty much the same use case as any standard code, smart contracts are just decentralised code after all.

In addition to the other points, there are other issues besides just cramming a raw number of bytes into a raw amount of space.

You need to balance disk space with IO capacity with compute with memory.

Simply replacing all of the 3.5" drives with an equivalent volume of SSDs probably leaves you well under-balanced on the memory/compute side and way overbalanced on the IO side. In addition, you need to develop hardware to interface with way more drives per chassis (massive-scale expanders). There'd be a lot of engineering costs associated with getting that much denser in terms of the number of drives per U (figure 6 or 8 times as many per U).

Of course, this could pay off if there was a cost benefit to denser servers, but, datacenter space at their scale is primarily priced at a function of how much (and what quality) power you need. Being denser isn't ultimately going save them much if any money.
I agree that if there were more consequences for compromised businesses, there would be fewer compromises... but it would also massively raise the barrier to getting a merchant account. Essentially, you'd live in a world where everyone used paypal or something like it. (I think apple pay would be in the running, too, but I think this might end up being natural-monopoly-ish)

The best way to solve the problem, I think, is to quit using shared secrets across minimally trusted parties. Public key cryptography is... I'm not going to say unbreakable, but it's pretty good. it's fairly secure. We need to enforce that on all physical card readers, which will make 'skimming' rather a lot more difficult, and then after that we need to figure out a card reader users can use on their computers and cellphones.

The technology is mostly there; most of my cellphones support some kind of secure wireless public key stuff, and most of my phones do too. We need to make this ecosystem work well, solve the software problems, and then make it so that your credit card number is just an identifier, not an authentication token.

It's also very beneficial to spread data across different drive manufacturers. If, for example, a particular HGST model starts to have massive failure problems in a year (massive at this scale would be like 20% failure rates), well, at least you still have a healthy population of Seagate/WD drives where the data on the HGST drives is also replicated to.

I wouldn't be remotely shocked if the Backblaze software takes drive model into account in data placement.

In addition to that, it makes sense from a purchasing perspective to spread your purchases around to many vendors. Make sure that Hitachi knows that they're not irreplaceable if they don't give you a good enough price you'll just buy more Seagate drives. Make Seagate always be worried that if you shifted enough purchasing to HGST they'll cut you a really good deal and potentially undercut Seagate.
