"your claim seems reminiscent to previous claims that humanity would soon not be able to grow enough food for the projected population"

This is a cautionary tale about something that stock market traders know well: never try to call the top of a bubble. You'll just look like a fool, and if you bet on it you will lose all your money.

The "Population Bomb" crowd in the 70s and the peak oilers of today tried to do just that: to call the top. They were not wrong about the underlying realities, but they were absolutely wrong about the timing -- which is nearly always the case. Bubbles almost always go higher and further than anyone ever expects or imagines.

We're exponentially growing on the back of finite resources that we are consuming without replenishing. That's a bubble. I don't know when it will pop, but it will. Question is what happens then, and will we have enough alternatives available to keep going or not?

On the counterpoint side:

Life faced a similar situation prior to the advent of photosynthesis. It was growing exponentially and consuming chemical resources that would have been depleted. Had photosynthesis not evolved in time, life would have likely mostly died out and retreated to small colonies around a few hydrothermal vents.

That might have been one of the first great filters. We seem to be past that one.
Why aren't they building Dyson spheres?
"No one wants to talk to us" is not a sufficient explanation. We need to be able to explain why we don't observe any stellar engineering. Assuming alien civilizations they either 1) can't make use of the most prominent energy sources around, 2) choose not to for some reason, or 3) we can't detect what they're doing.

1 and 2 don't make sense if you assume that there are many alien civilizations older and more advanced than us. 3 implies that we're fundamentally misunderstanding a lot about (astro)physics.
Why don't you just make up your own stuff?
A lot of people might die, but that alone doesn't imply that civilization goes away.

2 x 72 Mbps leaves a theoretical 336 Mbps of bandwidth lost to overhead, which seems pretty bad, even for USB. But I realize that dealing with multiple simultaneous streams is a harder problem than just raw bandwith.

Your point about the scan lines is interesting. I wonder if the drivers for your typical webcam can deliver partial frames, or if they need to capture a full set of scanlines in order to not drop the frame.

Surface-level democracy that disguises an underlying regime which holds the real power is a very common pattern. In these situations, we should call a spade a spade, not give into propaganda that calls the government a democracy.

For a US example, try voting the NSA or military industrial complex out of office.

Real functioning democracy is a very rare thing in this world. We don't get anywhere by pretending otherwise.
"people live cleaner year by year"

I'm not talking about cleanliness. That's a quality of life factor but ultimately it's not what's important. The important thing is supply, mostly of energy.

(It's also important to note that to a great extent the West has cleaned up its environment by outsourcing polluting industries to Asia, Africa, and South America.)

Last I checked we still got more than 80% of our energy from fossil fuels. That has changed very, very little in the past 50 years. My grandparents drove a gasoline car, my parents drove a gasoline car, and I drive a gasoline car, and the power grid where I live is powered by 60% natural gas and 15% coal. Where I grew up it was almost 100% coal, same as it was three generations ago.

We were supposed to be driving EVs powered by fusion reactors by now.

If you're rich you can buy solar panels and an EV and convince yourself there is no problem, but until that stuff falls geometrically in price to the point that it achieves mass adoption it's a luxury toy that will make no impact. Either that or the future will require that 90% of humanity be reduced to medieval subsistence-level poverty. That's not quite the collapse some have predicted, but I highly doubt that sort of neo-feudal civilization is going to go to the stars. So it counts for the Fermi Paradox. The universe may be filled with such small, limited, planet-bound intelligences.

I'm slightly encouraged by an apparent Moore's Law in solar, but storage is now the bottleneck. I'm also very cynical about technological advancement outside of IT and a few other narrow areas. I agree with Peter Thiel that basically all major technological advancement outside of computers and some biotech stopped around 1970. Cars, planes, power plants, etc. are all basically the same today as they were then.
> This indicates the formal death of the ecosystem to anyone but apologist hobbyists and thankfully we've gotten to a better place now.

A couple of things. First: "This", so far, is anecdotal and doesn't indicate much of anything, really. For something concrete, look at Unity. Maybe you haven't used anything built with it, but everything I've seen come out of it works just fine.

Second: Apologist hobbyists? That's not true and needlessly insulting. If your aim is to just marginalize anyone with a differing opinion please don't expect me to take you seriously.
So, if we run out of lithium, what are we switching to? lead-acid?
Google interviews are quite different from programming contests. In a programming contest, there is little time to think or talk, success is about instantly pattern matching problem to solution , copy pasting library Code, and pounding out a solution.

Interviews are 30min of discussion and 20 lines of code.
8088 MPH – CGA DOS Demo
This is an interesting calculation to do but the specific example needs improvement.

First, the calculation of the available supply is based on known,
existing reserves economically retrievable at current prices. Changes
in demand will change both the known reserve quantity and the price.
Lithium is currently about $1/kg, so there is plenty of room to grow
price to increase supply without affecting the cost of batteries. So
a reasonable estimate of lithium supply has to include both demand volume and price. Reserve
growth based on demand volume and price is a very tricky thing to forecast.

Second, the choice of 3.4 billion vehicles to "bring the entire world
to North American levels" as a goal is an unrealistic number for many
reasons. Regional economics, geography, and social density vary quite
radically around the world. The built infrastructure varies and
supports many different transportation modalities. It also doesn't
take in to account changes in technology, infrastructure, and social
organisation during such a radical transition. So a more reasonable
estimate would be to simply replace all vehicles on the road with
BEVs.

Last, the note could also be improved by doing sanity checks. For
instance, could the world production capacity of any other energy
storage mechanism, including oil, hydrogen, ethanol, etc. support 3.4
billion vehicles? It's always useful to compare what you are
calculating to the alternatives.

There are currently about 1 billion cars in use in the world. Using
just the reserve numbers quoted in the article it seems economically
feasible to replace them all with Lithium chemistry battery electric
vehicles.
I just looked at a driver I wrote several years ago. Each pixel is actually 2 bytes, luma and chroma. So it's 144 Mbps per camera. The scan line packets don't have any indication of which scan line they're from, so if you miss one you'll have the rest of the frame shifted up. I imagine reasonable drivers might drop the whole frame rather than show such an ugly artifact.

There is indeed a lot of overhead on USB. Each packet has to be requested by the host which polls each source round-robin.

If we assume that people continue to drive the same number of miles per year, the robotaxi concept won't actually reduce the number of cars being produced* . (number of cars produced/year=number of people * average number of miles driven per (person* year) * (1/average life of a car in miles) ). But it would do two other things. It would reduce the number of cars in existence at any given time potentially freeing up space (garages, driveways, parking garages, street parking, etc.) for other things. Also, cars would wear out faster (in time) which means you would shift the average age of cars on the road down. So on average it would also increase the safety and efficiency of cars on the road as well.

Imagine 10 people who drive 10k miles per year who own cars that last 100k miles (just for the sake of simplicity). Right now, those people would each own one car for 10 years. In the system you suggest they would all share one car which would be replaced every year. So they would be driving a (technologically) new car every year. Of course this assumes that none of them ever want/need to drive at the same time. Perfect usage like that is not likely, but you can see that shared usage would still have this effect (even if it is not as large).

* Neglecting the damage to cars which is not due to driving wear, e.g. corrosion. Taking this into account we would expect to see a reduction in the production due to being able to get more miles out of a car before it "can't" be driven anymore.

NVMe is about as simple an interface to a block device as it gets: read blocks, write blocks, and a few health/diagnostic commands. Commands and geometries that originate in spinning disks have been completely extricated.

I'm not sure that I'd want the protocol to get involved in the intricacies of backing store housekeeping as you propose. Newer generations of SSDs may not even have erase blocks or translation layers; do we want to have yet another protocol when the technology changes?

That is a really good question. The thing is that if they are powerful enough to actually do that, perhaps they have come up with something better?

I mean there could easily be a couple 1000 years between us, which means that the difference is at least as great as us and the Romans. The Romans might very well question why we weren't breeding more horses then, since we have such a huge need of transport and horses are the best way to do that.
Also from the Readme (at the bottom) https://github.com/cachethq/Cachet#addons
There's absolutely no proof in this.

The fact that a request with a TTL smaller than 12 does not trigger a response does not mean the responder is the host after 12 hops. Assuming none of the previous hosts misbehaves (they could be increasing or at least not decreasing the TTL) you can only conclude that it is none of the later hosts, but it can still be any of the previous ones.

That leaves you with Comcast AND China Unicom hosts and, considering that the replies you see in the traceroute results can easily be spoofed, it can be any third party as well.

Possible scenarios include (I don't say they are more likely):

1. Comcast is producing the responses, but only does so if the request TTL is large enough to make you blame China Unicom.

2. China Unicom hands the packets over to a third party after just a few hops in their backbone. The third-party sends ICMP Time exceeded messages looking like they are from other China Unicom hosts to make you blame China Unicom.

Conclusion: This is either an obvious attack from within the China Unicom backbone OR a more sophisticated attack where the attacker wants to a) hide his identity and b) blame China Unicom for it (I can't think of a scenario where b) would be a by-product and not on purpose).

Just saying. The sentences in the post that include the words "prove" and "proven" are simply wrong.
I mostly agree with this, but to be a little devil's advocate, it does look pretty bad for the local prosecutor, seen as in bed with the current system, to handle the case. Even if the shooting itself was completely clean - as it appears to be - it would still look better if an independent prosecutor was trying the case.

But then, the DOJ reports seem to show that, while the shooting itself was probably clean, that's about the only thing in Ferguson that was. With such a level of animosity between the population and the law enforcement system, is there anything that the system could have done at that point to satisfy the population? And the system has done plenty to earn that level of animosity - at this point, it's easy to see why the population is furious, even if the Brown shooting isn't the best case to focus their anger on. But people pay a lot more attention to a shooting than to countless hassles via tickets for trivial offenses and a legal system designed to make it as difficult and expensive as possible to stay on the right side of the law. And so we have the situation today.
2400Gbps = 3GBps

going from "b" to "B" is either 8 or 10 fold. As some of the other comments have noted. SATA uses 10 bits per byte.

so 2400 Gbps = 300 GBps (8 bit)

or 2400 Gbps = 240 GBps (10 bit)
Marijuana metabolites don't lurk in adipose tissue, waiting to sneak up on you and fuck up your brain or make you unexpectedly high for "months".

Laboratory drug panels — the kind used in pre-employment drug screens, or to test athletes — with sensitivities as fine as 20ng/mL can typically detect metabolites up to 30 days after cessation, in long-term, daily users with high body fat ratios. Casual, infrequent users will typically piss clean in less than a week.

Alcohol is something that you can take or not take on each day as you choose.

Tell that to a long-term alcoholic. Alcohol is one of the only known drugs for which withdrawal can be fatal.
I believe so. At my workplace we use Cachet for our internal tools and applications - we wouldn't want to pay $29 a month for something internal like that.

There are a lot of people using Cachet in the same way as we do and even for services or business that are making money.

Why a Soda Tax Is Unlikely to Work
In general these things tend to follow a logistic curve. It's a useful meta-skill to know when investing more time has marginal utility.

I think your examples are great, if you just change deadlift 400 pounds to maybe ~500-600 pound, (or roughly 2.5-3x bodyweight for adult men) [1]. Most adult men can reach a 400 pound deadlift in less than 2-3 years of lifting (that's <5h/week).

I mention this only because a lot of people here on HN are probably lacking physical activity, compared to what human were evolutionary selected for, and it's useful to know what can be expected. It's generally more than most people think.

1: See for example http://chrissalvato.com/2009/12/skill-guidelines-for-buildin...
Since SATA uses 8b/10b encoding, the data rate in bytes/s is actually 1/10th of the raw bit rate. The same applies to earlier PCIe versions. 6Gbps SATA can transfer 600MB/s (ignoring protocol overhead).

I don't really know why it's become standard to publish raw bit rates in bit/s and data rates in bytes/s with error correction taken into account but not protocol overhead, but those are the two kinds of numbers you almost always see quoted nowadays. Raw bit rates at least map pretty directly to clock speed, and I guess protocol overhead must be too variable and too complicated for most people to bother explaining.
I'm not exactly sure what your argument is. Sushi is local to Japanese culture, and just as you thought, Japan has some pretty decent Sushi for ~10$ (1000 yen), that already beats 99% of Sushi in foreign countries. I wouldn't call it gourmet, but it's prepared by a chef who knows what he's doing. That it costs more in California, where you don't have Tokyo's crazy Tsukiji wholesale fish market that allows them to have the world's best and freshest fish for reasonable prices every morning for 7 days a week, and where the job market for skilled Sushi chefs is much more a seller's market, doesn't surprise me.
A lightweight UI library for FirefoxOS apps

You'll want to find a build of UAE for Amiga emulation.

https://en.wikipedia.org/wiki/UAE_%28emulator%29
Awesome. The integration is really cool, though that's totally without digging in at all to compare it to live editing and workspaces (https://developer.chrome.com/devtools/docs/workspaces).

Looks like Firefox supports some form of remote debugging too (https://developer.mozilla.org/en-US/docs/Tools/Remote_Debugg...), though looks like it might be more painful to integrate with (https://github.com/caspervonb/amok/issues/10).

I do wonder how well this would integrate with SPAs - seems like it would be great for testing events/handlers/etc, but might be weirder (or at least possibly more work than just refreshing) for testing app starts and the like.
One Codex (YC S14) is hiring engineers to work on infectious disease diagnostics
One Codex – Genomic search and data platform. San Francisco, CA (https://www.onecodex.com).

We’re a software and biology start-up building a platform for microbial genomics – an essential piece of infrastructure for a world in which we increasingly understand health, disease, and our environment by transforming biology into data.

Our first application area is infectious disease diagnostics – where we’re already working with doctors, epidemiologists, and others at the world’s leading public health and research organizations. We were also awarded a $200,000 prize by the CDC for our work on “strain-typing” pathogenic bacteria, and are backed by some of the best investors in Silicon Valley.

We’re looking for talented software engineers to help us build towards our vision for a global genomics data network and enable widespread in silico diagnostics.

YOU’RE A GOOD FIT IF:

- You’re a generalist software engineer that loves hard problems

- You want to work on a technology product making an important real-world impact

- You’re excited about joining a small team and directly impacting the shape of its technology choices, product, and business

- You communicate well and work effectively with others

- Pluses (but not requirements): biology/compbio background; experience with Docker in production; prior experience with Flask, React, D3

WHY ONE CODEX?

- Important problem: We’re not only working to build a better diagnostic test for infectious diseases, but setting the groundwork for entirely entirely new clinical, scientific, and public health applications that will come with an improved, real-time understanding of “microbial space”.

- Hard, intellectually interesting challenges: Amongst other things, we are 1) applying and developing cutting-edge bioinformatics algorithms; 2) developing and deploying new data structures (really!); 3) finding better ways to manage messy genomic data; and 4) and running Docker in production. In short, there are plenty of near- and medium-term hard engineering challenges, and there’s more to our technology solution than just a simple CRUD app.

- Upside: We offer a competitive salary, meaningful above-market equity, and the chance to be an early employee in a well-positioned startup.

OTHER BENEFITS

- Full medical, dental, and vision coverage

- Flexible vacation policy and relocation assistance if moving to the Bay Area

- Whatever computing set up you prefer

"Venture capital firms don't do a great job on their websites of explaining what they invest in..."

Solution:

1 Entrepreneurs petition VC firms to all post a CSV file (Excel file saved as .csv) listing what they have invested in, dates, etc. Is there a single VC firm that does not have this data? Most likely the data has at some time been put into a spreadsheet or some form of report.

2 VC firms locate the spreadsheet, delete any confidential columns (Alt+Space, Alt+H,D,C), save as Comma Separated Values (.csv) and give the file to their web developers.

3 Web developers upload the file to web servers.

4 Entrepreneurs download CSV file.

Wow, that was complex. My head hurts.
I propose both ideas are related. That requiring a degree as a signal in the marketplace is warranted because degree holders tend to actually possess knowledge.
They are - but they don't forward all messages. All gateways are configured in detail which signals should be forwarded from Bus A to B and which transformation functions should be applied.

This means you won't get access to any signal from any bus.
