FWIW, the small team has been fantastic and responsive since the beginning. (I've been on the betas and helped develop some of the early controller scripts. check the community pages to see what we've done)

I got a NFR license for helping out early on, and ran into the activation limit initially. (testing on all platforms, etc...)
I emailed them a few times to deactivate my current systems initially, then they added the option to their account management page.

If its a deal breaker, I suggest emailing them and seeing what they say. It wouldn't surprise me if they upped the limit or did something to help you out. They're an awesome group who really want to work with the community and users.

Not affiliated besides what I mentioned above, just a happy user. Best of luck, if you have any questions PM me or reply here if you think relevant to others :)
Ok so I am curious about the "collectivism" story. I mean, we as species have been talking care of our elderly and injured for like what, 50,000 years or 100,000 years or whatever? Seems to be working well.

And, if we all chip in, we can have nice things. Roads, water, electricity, museums, libraries, courts, police, etc.

Is that bad?
Ok, I can appreciate skepticism. But do you have any arguments to advance yourself? Wage gaps are hugely complex, and the stats put out by the labor department (fuck Glassdoor, whatever) are both controlled, detailed, and fairly damning. Women make less on average in almost every field, women are employed less in high paying jobs, and the jobs that are heavily weighted towards women do not pay nearly as much. I don't understand how people can brush off single statistics while ignoring the absolutely massive cache of freely available evidence.

Also, starving people of hours is just as effective at reducing costs as lowering the hourly. I don't think it's in your favor to argue that's something that should be controlled.

I agree with codegeek on the tag line, it's confusing and I'm not really sure what it means.

Also, I think it should be more apparent that some "get started" buttons shoot off an intro email. I know there's a small disclaimer under the button (which I noticed after getting the email), but those types of disclaimers are usually (and easily) ignored.

I was expecting to hit a landing page, or at least get more info on the company, but was instead sent an email which I wasn't even sure I was interested in getting. Even changing the verbiage from "get started" to "request intro" for offers that fire off intro emails.
Great points. It is an odd fact that Microsoft generally avoided writing operating systems on or for Intel x86 processors [1], and started the development of both NT and CE on Risc processors.

Meanwhile, Linus had a PC with an Intel 386 processor, so that's what he started Linux on and for...

[1] MS DOS was based on code that Microsoft bought in, not having time to develop it from scratch. However, Microsoft did have some success on x86 with its PC version of Unix, which was called Xenix.
I may be incorrect, but it seems to me that the US currency will ultimately back that. If the government does not have the ability to pay, then it will have to print money to cover the difference, devaluing the currency. It's probably a reasonable position, but it seems to me to be vulnerable to poor timing. For example, if there is a debt crisis, you may have to raise interest rates at exactly the time when you don't want to. When I see very high prices for houses (in relation to salaries), an aging population, and a pension system that can demand money from the government at will... it makes me a bit nervous.
Walmart does stuff that is quite a bit more sophisticated than you imply, such as having quite a lot of inventory already in motion on trucks ready to be re-routed to where it is needed. It is my understanding that Amazon adopted some similar approaches to make sure it's regional warehouses remain stocked.

For that matter, Walmart certainly does ship in bulk (as in, whole trucks), but the contents of those trucks aren't measured only in whole pallets of items, but also smaller replacement inventory amounts (ie. when an item is rung up on the register, the system increments by one the amount going out on the next shipment to that store, which might be the next day, not to mention the amount being re-ordered from the supplier, etc.).

Not to mention that Walmart does handle a lot ofbretail e-commerce purchases that are shipped to individuals.

Oh, and Amazon at one point was poaching a lot of Walmart's top folks, so there was obviously something they wanted to learn: https://www.cnet.com/news/amazon-com-wal-mart-settle-lawsuit...

(Wow, has it really been 19 years? Damn.)

Anyway, the comparisons between the two companies are far from straightforward.

Some context: the author, David Baker, is a preeminent figure in the world of protein structure prediction. His lab has consistently had the best protein structure prediction software out there (Rosetta). They recently released a paper detailing the structures of a large number of unknown proteins using their technique as an aid [1].

Some of the ideas in this article are quite cool, but I think it's important to add a caveat: we don't often know what structure will yield what result. In other words, if I want to do X, I don't know what protein structure will get me X, which makes it hard to engineer such a protein.

Nevertheless, when you have some understanding of the problem, you can in fact engineer proteins. Baker gives several examples in the article. In many of those cases, the best approach is to start with a variety of engineered proteins, then use in-vitro simulated evolution to pick the winners and get pretty substantial improvements over the original design.

Protein engineering is quite a cool area, and hopefully over time we'll get better at understanding the other parts of biochemistry so that we can more effectively design useful proteins.

I love potassium permanganate. Growing up in Soviet Union, we used to add potassium permanganate to bath, supposedly to clean your skin. But I love it for its oxidizing properties. Mix potassium permanganate with magnesium shavings, and you have a pretty powerful explosive mixture. Put a drop or two of glycerine into potassium permanganate and glycerine spontaneously burns. There are tons of interesting experiments you could do with potassium permanganate... So many wonderful memories...
> IIRC, PP can be a precursor to chlorine.

Converting KMnO₄ to Cl¯ would require a nuclear reaction. Chlorides are generally soluble, so it's not going to cause an insoluble salt to slowly dissolve as a permanganate salt precipitates instead. It does appear to be a stronger oxidizing agent than Cl₂ (and Cl¯ and ClO¯ and ClO₂¯), but there are likely better reducing agents in most water than dissolved chlorine ions.

Sorry, but integral as done by a neural network is not generally reversible by taking out terms, unless it's a strictly linear no threshold neural net. This one is not.

Same problem with the binary functions like most kinds of digital electronics - they're typically combined in highly nonlinear ways.

However, knocking out a whole IC and seeing what it did is more reasonable and about the level we are at when understanding functions of subsystems in the brain.

Adding to the suggestions here, there's another benefit to playing with hardware.

If they start plugging in basic effects pedals, they'll learn about signal flow and signal chains that are relevant to all styles.

There's no fundamental difference between a microphone, a guitar or a drum machine plugging in to a delay pedal.
Learning the basics of EQ (bass, mid, low) gets them on the path to studio mastering if they're interested in that side later.
If they decide they don't like the creative side, they have the basics to learn live sound tech or sound engineering.

Good luck and have fun :)
They were in an uncomfortable position.

They had to add scripting capabilities, and be first at it (else MS would be the first). They had to make the language instantly understandable by an average programmer — that is, someone who has a Basic / Pascal / C / Java / Perl background, and an hour of time to get acquainted and like the language.

So they created a scripting language with a familiar C-like syntax, very few restraints, and a bunch of "convenient" magic that helped a person to create a simple animation in the browser on their very first day, by mashing things together.

This was a terrible strategy to create a nice language for safe and comfortable development of large applications, especially full desktop applications 20 years from the inception date.

It was a very well-working strategy to get mass adoption in no time, and own the market the same year in the face of mighty competition. This is what business cared about, and this allowed Netscape to stay successful for a few more years.

Alas.

Now we have WebAssembly (which resembles a stripped-down JVM from 25 years ago), and soon will be able to efficiently compile our favorite "real" language to run in the browser not through JavaScript.
We do know a lot, but I would argue that much of what we know is not a result of the techniques used in this article. The things you mention are results of lesion experiments or observations, which are decades (or more) old.

Most of what you mention is sort of negative information - what happens when the brain breaks. How it works is a fundamentally different question, and I suspect we'll only get real understanding by building computational models that are able to do similar computations to those the brain does.
Actually they were better than that. Users loved them (check out the star ratings on user reviews) and some are still in use.

The design was fundamentally flawed for other reasons, but they performed reasonably well compared to rival tablets, while also offering multiple log-ons, multi-tasking and full Microsoft Office, which those other tablets lacked. They also supported Active Directory, ditto.
Fair enough. Edited to reflect that.
> a single atom of the element holmium carefully placed on a surface of magnesium oxide. A special-purpose microscope uses a tiny amount of electrical current to flip the atom's orientation one way or the other, corresponding to writing a 1 or 0. The researchers then read the data by measuring the atom's electromagnetic properties.

I'm not sure I could have recalled the existence of the element holmium, I've never heard or read much about it. I looked it up, and found the likely reason it was used for this research:

"Holmium has the highest magnetic permeability of any element and therefore is used for the polepieces of the strongest static magnets." https://en.m.wikipedia.org/wiki/Holmium

I don't know if we'll see practical atomic storage or if more than one bit per atom is physically possible, but in theory there's enough space in an atom to hold millions of bits. But I think you have to get to black hole density... https://en.m.wikipedia.org/wiki/Bekenstein_bound

> That is a bit rough around the edges.

Correct. It would be one thing if Celsius is somehow tied into the rest of the SI units, but it is not, which means we can replace it.

> It's not even calibrated properly.

Who cares if they got the calibration of Fahrenheit wrong, at the end of the day it's more usable than Celsius for humans.

0 Fahrenheit is the temperature when it's really cold outside, 100 is when it's hot. It doesn't get simpler than that. If you are outside those ranges you need to take special precautions. No, I don't care about mercury either, but I do care to know when it's cold.

It's not that hard to remember 32 for ice. With Celsius you need to deal with negative temperatures all the time, and worse, the size of the degrees is too coarse.

> 100°C is "water boils"

And exactly how often do you need to measure the temperature when water boils? Probably about as often as I freeze mercury. So 100 is a very useless range on Celsius - you are using your "best" numerical range on useless temperatures.

On the other hand it's quite common to want to know when it's hot enough that you will sweat. Above 100 (body temperature) you will sweat.

Labs and Ovens don't really care about which exact unit, so let them deal with the higher (or lower) numbers - the only time it matters is for ordinary humans checking the weather.

> I don't know how you can praise Kelvin and slam Celsius

You misread, I did not praise Kelvin, I said we could replace it.

That is way too simplistic as well, as this model is time invariant. Most instruments, due to physical nature of excitation, are variable in both frequencies and phases over time.

It is the main reason why modelling physically is the best way for realistic results right now - lossy lumped finite element models typically - digital waveguides are one of such models.

In such a model you can incorporate nonlinear damping and resonance functions over time at desired accuracy.

Lol. I'm sure that there are people at the CIA / NSA that are much better at software than me, but I highly doubt it's pervasive.

I read the Snowden leaks. I know what type of tools they're using. I know the type of holes that their public facing infrastructure has. I know the type of holes that their government officials that they're supposed to be protecting have. I know how fucked the security environment is right now. The CIA doesn't even use HSTS or CSP headers for fucks sakes (lol, they get an F on observatory.mozilla.org) so we are not dealing with an organization of godlike power.

Trying to understand what you're saying -- I believe when you say "their preferences" you mean that people want "basic as-pure-as-possible H2O that they paid for". However, all water that we drink is purified by a wealth of processes. That's not pseudoscientific, that's real science. Our purification is the reason we don't get cholera, for example.

If you mean that people want non-pink water, I think that's reasonable. But I also think it's reasonable that the reason the pink color is explained by the actual purifying process. I too concede that the water controlling authorities screwed up by using too much of the chemical, but it seems not in a dangerous amount, and they did well to communicate exactly why, and they also conducted tests to ensure safety of the water, thus effectively following up and checking the potential problems with their screw-up.

As far as government mistakes go, I think this one was relatively mild and handled in an adequate manner.
