Robotics is a very diverse field with a lot of different problems. There's plenty of people in it who do hardcore AI. A lot of the time, the results developed by roboticist can be used more generally, they just picked robotics as their application domain. Robotics also has some different constraints that can make problems interesting -- namely computation time and safety requirements.
The sensing system used was from "Zomega Terahertz Corporation", which had a web site "z-thz.com". That company seems to have disappeared at the end of 2015, but it's still in archive.org. Can't find any info that indicates what happened to them.

Zomega was one of the few companies with a true terahertz system, at 2THz, or 0.006in wavelength. Other "terahertz" products seem to be around 100GHz, which is much easier to reach; there are 77GHz automotive radars.

Zomega systems had already been used to image hidden layers in paintings, so looking into a stack of paper wasn't a big stretch. This new paper is mostly about a data reduction technique.

Well, that's the question facing us, in the large: Do we create artificial scarcity to keep our bullshit going? Or do we, as a species, learn to relax and stop effing with each other?

We had to hit each other with sharp bits of metal for a long time. We don't have to do that anymore. Do we notice or not?

Bucky Fuller pointed out that, in terms of our technical ability, post-scarcity arrived in the seventies. We can call it with the invention of the microprocessor. (We don't need to postulate fusion, as there is already a serviceable fusion reactor available nearby: it's that thing in the sky that burns your eyes when you look at it.)

Let me repeat that because it bears emphasis: We are already in a post-scarcity condition.

Put another way, all our problems now are psychological. Which is kind of what you were saying, or not?
> you cannot expect all of them to SSH into a single machine

Why not?

I can do exactly this (KDB warning). Building one or two very beefy machines is 1000x faster, and a lot cheaper than a Hadoop setup.

> The author of the blogpost/article, completely … The author completely … [Here's my opinions about what Hadoop really is]

This is a very real data-volume with two realistic solutions, and thinking that every problem is a nail because you're so invested in your hammer is one of the things that causes people to wait for 26 minutes instead of expecting the problem to take 12 seconds.

And it gets worse: Terrabyte-ram machines are accessible to the kinds of companies that have petabytes of data and the business case for it, and managing the infrastructure and network bandwidth is bigger time sink than you think (or are willing to admit).

If I see value in Hadoop, you might think I'm splitting hairs, so let me be clear: I think Hadoop is a cancerous tumour that has led many smart people to do very very stupid things. It's slow, it's expensive, it's difficult to use, and investing in tooling is just throwing good money after bad.
By the principle of elimination by bottleneck. As the crystals grow into the pigtail, the lagging crystals hit the already-formed leading ones or the mold surface, leaving a primary, single crystal grain to exit the pigtail and grow across the blade proper. This would be almost impossible to happen without the pigtail because multiple crystal grains would grow in parallel across the blade.
I had the chance recently to see the Mayor of the City of London's (the strange city-within-a-city bit of London) two Rolls Royce's they keep for formal occasions up close. They are super rare (only ~400 ever made), worth a whole lot of money and looked amazing.

I'm not a car person but you can't help but feel a shiver when you see a car like that. The engines where the same as the ones they used in the Spitfire fighter planes during WW2 (6.5 liter v8!), full white leather interior, a retractable partition between the passengers and the chauffeur.

I know this isn't strictly about the article but I thought I would share anyway. Rolls is one of the things that makes me proud to be British.

I think that would be news to most employers in the US, mainly because it appears to not be true and the details vary wildly by state

https://www.workplacefairness.org/voting-rights-workplace

"In some states, the law designates a specific amount of time that workers must be allowed off to vote. ... Some states require your employer to give you time off only if you will not have enough time to vote before or after work, while the polls are open. Most but not all states prevent your employer from firing or disciplining you because you take time off to vote."

In the state I live in, there is no law requiring your employer to give you time off to vote.

And if something goes wrong, you can at least narrow down your search to unsafe areas of the code.

No. That's only true if the unsafe code presents a completely safe interface to its callers. If the safe code opens a hole in Rust's protection system, which is very easy to do, you can now have C-type no-idea-where-it-is bugs.

I think sharing control of funds is a weakness. Not just when it comes to smart contracts that will inevitably have bugs, but for organizations in general. Instead, we can create organizations without boundaries and govern them the same way we govern genres of art—if you do something that aligns with the brand, your action is part of the organization.

That's why I built Benefactory, a platform for decentralized nonprofits. We can weave individual efforts into an organization with a strong brand so it's easier to attract recognition and further contributions.

You and your parents history in the US in general can have a an affect on whether you can convince a bank to give you a credit card or not not on the credit score.

I am not talking about credit card history but about history of being a US citizen, having a bank account etc.

I think a lot here are missing the point.

The question is not about your credit score but about getting the credit card to begin with. Once you get the card they assign you a credit score but in order to get it you have to start building debt (and as a foreigner I had to do that with my own money)
His point specifically is that tax write-offs don't reduce how much you have to pay overall. They may even increase it. They just redirect some of it to other purposes such as research instead of paying taxes.
Because humans are only humans, we are biased more if we are emotionally involved in something, more time you spent creating something, investing your time, more you are biased. It's about level of bias also, someone that is only using some technology is not so biased as someone that is creating one. It's psychology 101.

This is seriously messed up.

As I said in another comment, these organizations have serious problems that need remedying but they have almost no control over the underlying root causes of the US' diabetes epidemic. I wouldn't necessarily argue against a problem with leadership and a focus on fundraising, but there are thousands of people who work under these organizations who often give up promising careers and their own time and money to make a real difference in communities that are outright ravaged by diabetes. Focusing on orgs like JDRF and the ADA as the "bad guy" only exacerbates the obsession with managing the symptoms as opposed to dealing with the underlying causes (mostly socio economic, political, and ecological in my personal opinion).

If you really want to focus on organizations, lets talk about the FDA and the outright corruption and thievery between Medicare/Medicaid and insurance companies. In the medical industry "diabetes" is a codeword for "huge profits from captive, disadvantaged markets" and until we start addressing those issues no amount of reform in 3rd party orgs will do anything.

The point is that our problems are shifting from physical ("How do we eat?") to psychological ("Where shall we have lunch?").

I've heard it said that, "even God hesitates to offer anything but bread to the starving man."
The only point of the paper is that the previous publications sold their systems primarily on performance, but their performance arguments had gaping holes.

The C# and Rust implementations have the property that they are easy and you don't need to have any specific skills to write a for-loop the way we did (the only "tricks" we used were large pages and unbuffered io in C#, and mmap in Rust).

The point is absolutely not that these are the final (or any) word in these sorts of computations; if you really care about performance, use FPGAs, ASICs, whatever. There will always be someone else doing it better than you, but we thought it would be nice if that person wasn't a CS 101 undergraduate typing in what would literally be the very first thing they thought of.
Yeah, with lots of weasel words and written by people who are not qualified on the topic.

I am curious - Are the bacteria really "evolving" at each subsequent boundary? In the article/video, they specifically mention "mutations". That says to me, that the bacteria are literally experiencing mutations within their nucleotide pairs, that results in them becoming more resistant to the drug?

Couldn't it also be that among the initial population, there existed 1 (or more) very very strong bacteria? At each boundary, the weak ones are dying off (hence the pause in growth) while the strong ones continue to reproduce. Since they're strong, but few, you witness a lag in overall growth of the population which the article is saying is the "evolving" process, when really it's more of a filter process. Filtering the strong, from the weak, by progressively stronger antibiotic strands.

I guess ultimately I'm just wondering what they specifically mean by "evolve" and "mutation".
For another option, similar to the Udacity course, I recommend this: http://www.dataschool.io/machine-learning-with-scikit-learn/

That really varies by jurisdiction. Currently, I'm encouraged to vote at a particular place, but if I wanted to vote somewhere else in the county I could. ISTR some cities I've lived didn't even assign a particular place, so I just voted where it was convenient. One probably couldn't get a ballot for city elections, in some other city.

Maybe that was his point, it was absolutely not what he wrote though. I won't contest that any redistribution scheme will not work flawlessly, but nor will anything else! So if the argument is, it won't work because it's run by people, that's just silly, as any alternative will have the same 'limitation'.

Now again, the fact that there is corruption in many countries and money is used wrongly simply means there might be initial or additional work be done, but it definitely does not mean it's inherently not possible, there are plenty of government with low corruption, too.

Finally, what's the alternative? Let the market work and private companies, which I highlighted have the exact same flaws as the government, possibly just on a smaller scale!?

Just putting our heads in the sand and saying this will never work is not a way forward, unless you think of course there's no problem in the first place.

Yes, it is literally just Ubuntu underneath, but they don't mention that on the release notes—it bothers me that they're not more open about that.

Every two years, they take the latest long-term support (LTS) Ubuntu release and then install quite a number of their own applications to replace stock GNOME and Unity ones. To their credit, they have a good eye for UI/UX and actually write applications—not just themes—that are simple and look nice. They care about fonts, colors, etc, and even have some decent style and code guidelines for developers:

I have been feeling that way ever since two years ago when I first looked at the language. I still don't understand why this language has such popularity. It's really bad for the reasons mentioned. C++ is a solid language where you can do everything you want and also write memory safe code in a clean way with unique_ptr. C++ is not perfect but to me no alternative come close yet, rust and go comprised.

I'm confused by this argument; how does predictive policing relate to measuring department performance? The biggest concern I can see is that putting more police in certain neighborhoods will bias the input data for those models (presumably police reports), but this doesn't seem to be what this section of the article is saying. It also doesn't seem like a good reason to avoid computer models, but rather to increase transparency.
I would prefer making it a national holiday since I can not vote it would be an extra day off for me.

Weekends in the US aren't going to get you more turnout anyway. Plenty of the country works on the weekends so it's not a help there and for those that don't, given taking hours out of your already limited free time or using your weekend for yourself, voting isn't going to win out in a lot of cases.
I understand and respect your opinion.

Your opinion does not give you the right to stop others from voicing theirs, and working hard to achieve what they think is a worthwhile goal.

The fact you ignored that's what my comment is saying, and merely paraphrased your article makes me think you don't care about other people's opinions and ideas, which is a really, really great way to make people not care about yours.
I would say those are analytical, but not creative.

> "deploying a sustainable universal health insurance in the US (either public option or single payer)"

Why involve the insurance companies at all? They're just a drain on the US healthcare system.

If you cut out the insurance companies, changed the rules about price gouging in the pharmaceutical industry and engaged in preventative medicine (such as offering support to those who wanted to lose weight), the US could easily afford publicly funded healthcare. Other countries with fewer resources have managed it just fine. Even if you have to raise taxes to do it, you could do so and still leave people with more money in their pocket compared to when they were paying out insurance premiums.
There will be a huge loss of jobs in the next 10 years, not job creation. At some point, self driving cars will exist with no driver, and around the same time, self driving trucks. Truck driver is still the most common job in many states [0].

You'd want what is sometimes called a four-season RV; you're going to need a bigger truck. They tend to be among the most expensive options; they're heavier, and more densely insulated. But, keep in mind that one of the benefits of living in an RV is that you can follow good weather. No reason to freeze your ass off, if you can just drive a few hours to a lower elevation.

Arctic Fox is among the best known four-season RVs. I don't know of any other manufacturers who specialize in that area off-hand. Modern RVs are better insulated than older RVs, in the general case, especially when comparing similar quality levels (e.g. a new Airstream or Winnebago will be better insulated and energy efficient than a similar model made 25 years ago...but, 10 year old models are probably comparable to current models, and will often be obtainable for 1/3 the price).

With a travel trailer, there's much less concern about needing to be handy than there would be a with a motorhome. While things are going to break, and things are going to need work, that's true of new or old RVs. My motorhome (which was 7 years old when I bought it) constantly needed minor repairs. Likewise, my 32 year old Avion also constantly needs minor repairs (and it needed and still needs some major repairs).

Sticking with ~10 year old trailers is probably the right time frame for someone who has no desire to have a fixer-upper (I don't recommend fixer-uppers, no matter what, as they always cost more in the end). But, if you start searching well before you want to leave, you can be extremely picky and you'll find someone that has loved their trailer, and kept it in great condition. A lot of trailers only see seasonal use...so they've only been lived in for maybe 6 months, even if they're 10 years old. If the owners winterized them properly, and kept them covered or at least protected from direct sun and such, a ten year old unit can be damned close to new. Higher quality trailers hold up better to aging than cheaper ones, so look for the high end brands (there's too many of those to list, but if you spend a few weeks checking out RV dealers, and RV shows and reading some forums, you'll get a feel for the ones that people really like).
Yes, moving to the tax system as proposed would require a massive reduction in government spending.

>However I don't understand how you can think tax on trade is authoritarian yet other tax forms aren't.

Land, and to a lesser extent the property that's built on it, can more justifiably be taxed, because an individual has less of a natural right of ownership over it.

This is due to land being a natural resource, that derives almost all of its value from its natural form, rather than the value the party that appropriated it added to it.
