Can you point me to some other publicly analyzed lightweight ciphers that are better choices than speck/simon? From my review of that space I got the impression that speck and simon are the more reasonable (and probably also more reviewed) designs.
Yes. You are right. I didn't give that part enough credits because of the focus on smart pump in their PR and the poorly written article that agitated me more than it should. My bad, apologies.

I think the problem there is that VCs are mainly interested in potential big hits instead of niche markets. From my experience, there are not many complaints on the comfort of the pumps. Or, let me correct that, not at the size of $750,-. If they would drop their price to be high-end but in range of current offerings it might work. Just like any other high-end line of products it's a quality vs price trade-off. Right now the balance is skewed.

Some other issues I foresee:

- they say they save 10 min cleaning after use. Cleaning ours does not even take 10 mins. Disconnect, throw in steamer. Done.

- they use water instead of air. When water stays behind it gives fungus. Doesn't this require more cleaning? (Did not check how it works).

- setting up now takes 10 more minutes if i watch their movies. Filling with water, no bubbles..

P.s. Did your wife try another brand? So is she pleased comparing it to other top brands or just pleased without comparison?

Low Profile MacBook Keyboards – More Usable?
It took quite many many hours of use, but it seems like the new low profile MacBook keyboard is finally feeling more usable to me than the old "deep" style!

Still comparing 13" model vs. 12" model for keyboard usability.

Curious if anybody else out there has feelings on this matter after quite a lot of hands on use?
There were "copycat" Toynbee tilers in the mid-to-late 2000's. I suspect a reasonable number of the tiles in more remote locations are not the work of the original tiler.

Case in point: I found a "Toynbee Tile" in San Francisco on Geary west of Union Square in 2007. I posted it on my blog the day we found it, and there was discussion in a message board about it the next day: https://web.archive.org/web/20080325024107/http://resurrectd...
> She and her husband, Jeffrey Alvarez, managed to raise $6.5 million from investors after starting the business together in 2013. But they’ve recently hit a wall. With few VCs willing to fund the product, they’re turning to Kickstarter in the hopes of keeping their company running. The campaign, with an initial goal of $100,000, is expected to start Thursday. “If VCs don’t want this, then we know parents and mothers do,” Alvarez said.

Is the $100K purely to demonstrate potential demand? Seems like a drop in the bucket compared to the $6.5M they've already received.

> The breast pump market is dominated by Swiss manufacturer Medela LLC, which got a boost in the U.S. from an Obamacare mandate that insurance companies must cover the cost of pumps for new moms. Most devices use hard plastic cups and an air suction system. They’re often loud and sometimes painful.

> The Naya’s soft suction cup mimics the feel of a baby’s mouth and distributes the suction over a broader area of a woman’s breast.

I'm hardly an expert on this but mimicking a baby mouth doesn't mean it's not going to be painful. Soft suction cups seems interesting though it's also something that could be added to a regular pump.

> Alvarez said the Naya delivers 30 percent more breast milk and is 20 percent faster than alternatives, thanks to a unique water-based system.

Now we're getting to something worthwhile. 20% of 45-120 minutes per day is quite a savings to the right person. I'd imagine it'd be particularly important to women that pump at the office.

> The company is also planning to sell a smart bottle that will be able to track the volume, calorie count and fat content of breast milk and inputs them into an app. Mothers would be able to use the software to monitor how much they’re pumping, how much the baby is eating and how much milk is left in storage.

This is utterly useless. I'm sure some idiots (particularly first time parents) will want these type of tracking features because they think they're important. But sensible people and anyone with more than one child will realize how pointless they are.

> Customers are asked to pay a serious premium for those features. The company was selling the Naya for $999 until Thursday, when it lowered the price temporarily to $649. A typical Medela pump is about $250. Naya is now pitching a lower-end model without a rechargeable battery or certain accessories for $399, though the price will go up by $100 eventually.

That's an obscene amount of money for a breast pump.

> [... truncated ...] But the couple still couldn’t raise money.

Bias deterring funding aside, I don't see how this company succeeds given their pricing and lack of true improvements over the status quo.
Looking at the year over year data:

http://www.arctic.noaa.gov/Report-Card/Report-Card-2016/ArtM...

Greenland is losing ice at around 200Gt/year (this is also in your second link). And I don't see where you get the 50Gt/day gains. Unless the graph is lying, it's in Gt/day. Ranging from gains of about 12Gt to losses of about -8Gt over this past year. Quoting your source:

Over the year, it snows more than it melts, but calving
of icebergs also adds to the total mass budget of the ice
sheet. Satellite observations over the last decade show
that the ice sheet is not in balance. The calving loss is
greater than the gain from surface mass balance, and
Greenland is losing mass at about 200 Gt/yr.

It's all fine and dandy to link to data. It certainly makes your post look more legit. But when your links directly contradict your text you should either find other data, or reconsider your stated interpretation.
Not really a useful concept since it’s purely subjective and may not meaningfully exist in any way at all.
Fellow flight-o-phobe here.

> "You are less likely to be in an accident in a plane than in a car".

> The above is a true statistic, but more nuance is required.

Regarding the "nuance": something I've never seen before, but would like to see, are these risk numbers adjusted for drivers that are not at-fault.

Example: If I have a reported N% likelihood of being killed in a drunk-driving incident, but never personally drive drunk, is my personal risk-exposure really N%? It seems like it would be lower.

My instinct is that these blanket-statement risk numbers may overstate risk for competent drivers. Not so on an airplane, however, where passengers have zero influence on how an event may play out.
I don't think your analogy holds up;

The hypotheticals aren't comparable, nor is the prior available information - and even though the Intel AMT/ME situation is egregious, explaining it simply as "a backdoor" is an oversimplification.

I'd agree that probabilities with regard to what is reasonable to assume (the operative word here) shift as a consequence of circumstantial information, but you can't really draw any conclusions based on that - hence the burden of proof, i.e. the presumption of innocence in your analogy.
Figures put 14-20 million unoccupied houses in the US. A lot of those are just rich people buying valuable real estate and hoarding it as a store of value, but a lot of them are also in locations where nobody who would want to buy them can afford to live because there is no work available. There are thousands of ghost towns in rural America which depopulated for a wide variety of reasons since the 70s but all could be cheaply renewed if people could survive living there without guaranteed constant employment.

So its not that the whole housing market just moves up the value of UBI and nothing changes. UBI introduces a new market of houses that currently are unsellable and rotting.

Those are obviously not a long term solution, but the existence of UBI and the economic pressure it produces will incentivize builders to develop the cheapest possible living conditions to supply to people living on UBI. That almost certainly would be an entirely new model of building - constructing for density, but without the limitations of building in already densely populated areas.

I'm not sure that it gives good incentives to have it directly linked to GDP. I think it would make more sense to have a circuit-breaker type provision where if GDP increases by more than x% the amount increases by y%, but I doubt we would want to decrease it immediately when GDP decreases, since that has the potential to cause a runaway feedback loop.
I had mixed reactions to this article. On the one hand, as a parent I've often thought about neglected business opportunities to meet certain fertility, pregnancy, and parenting needs, and this article resonated with that for me.

But on the other hand, as you're mentioning, this area is a lot more complex than the article is letting on.

My wife pumped exclusively until our child was about 1.5 years old, and one thing I noticed was that as she went on, she went from various hand pumps to various electric pumps, and then back to hand pumps for several months because the paraphernalia and power requirements involved were more troublesome than they were worth.

I remember reading about this pump in early stages, and it sounded wonderful, and still sounds nice. But I'm not sure my wife would have actually been interested in it after a certain point in time, because it's still bulkier than a basic hand pump. At that big of price, they'd actually be losing out on two points, the extreme price and the bulk. Maybe going into pumping at the beginning, she would have purchased it if it had been available, but it's difficult for me to say. It's very expensive for what you'd be getting relative to the alternatives.
> But, if the UBI is set to a percentage of GDP, then as overall wealth increases

That's an extraordinary assumption. The majority of nations in fact do not see routine, much less significant, overall wealth increases. Major economies as varied as Germany, Mexico, Russia, Britain, Japan, Brazil - have seen near zero economic growth for the last decade. The US appears in fact to be starting a protracted stagnation of growth, due to its extreme debt (in most every regard from public to consumer to corporate), resulting in problems similar to those experienced by Japan due to its egregious debt problems (low productivity gains, weak or negative income growth, weak or negative real wealth gains, low GDP growth, etc).

UBI can't be implemented in a nation in which population growth is falling rapidly (fewer workers to carry the tax burden), while debt is already sky high, incomes are stagnant, and existing entitlement system IOU's are already set to bankrupt (either directly via default or indirectly by currency debasement) the government (with already dire perpetual half trillion plus dollar deficits with the public debt soaring toward $30 trillion next and annual deficits set to climb toward a trillion dollars).

Sure, what you're describing is the quantity theory of money, but there are other reasons why you could see inflation given a universal income, depending on the circumstances.

If you consider the velocity of money, you will almost certainly see inflation on consumer goods if the money to be redistributed would have otherwise just sat in some rich guys's savings account.

There are also inflation expectation to consider, liquidity traps, the actual demand for money, etc.
Most snowflakes aren't, the vast majority of snowflakes are of the "irregular" type. And to answer another person's question above "Why are snowflakes 2d", the irregular ones aren't, and there's a lot of symmetric ones that aren't 2D either[1].

The ones people like to photograph are the symmetric 2D ones, so there's just a lot of selection bias going on. But, the ones that are symmetric, are that way because all of the branches experienced the same environment on the way down. Most of them are not perfectly symmetric, and differ quite a bit, but photographers tend to select only the most symmetric ones.

The website in [1] has an overview of how to get started in snowflake photography if you want to give it a try. I've done it quite a bit myself, but unfortunately I don't get the opportunity very often.

How do cancer researchers and machine-learning engineers cope with the triviality of it all?

(My brother-in-law works in cancer research. Most of his daily job consists of drawing blood samples, growing cell lines, killing mice, and managing lab techs. He has had one paper published in Nature [1], which, if you read the abstract, will make your eyes glaze over. I work in machine-learning. My daily job consists of labeling training data, debugging ETL code, and looking at relevancy scores and figuring out where I went wrong.)

I think it helps to realize that this is the human condition - big developments are built out of little developments, and often aren't recognized as such until years after the foundations are laid. Usually, when we think of big prestigious work, it's because of an information distortion in our brains, which aren't equipped to track the minutiae of all the little steps it took to build something we notice, and so only latch onto the thing as a whole and whatever names we can attach to it.

If you're bored at work, quit! Start working on some hobby projects where you're doing what you want to be doing, and then look for people that might have money and be willing to pay you for it. But basically all important work consists of 90% drudgery; you have to enjoy the drudgery and believe enough in the whole that it makes it worthwhile.

> Why doesn't Canada put a rule saying all work must be done by Canadians.

Because the government doesn't want to be seen as xenophobic. One of the major talking points of the prime minister and his government is "diversity is our strength". They also may want (depending on the department) to be seen as distancing themselves from expenses, not necessarily engaging in cost savings per se, but in cost-saving-style behaviour.

> Even if its cheaper keeping the money in country seems better than sending it to India.

Having worked with IBM-sourced contractors working in the U.S. and Canada, I can say that at least the ones I worked with were pretty useless regardless of where they come from.

The problem is that the government is bidding by familiarity rather than competence, and isn't willing to hire anyone competent enough to build a genuine team. When they tried their Shared Services Canada thing, it was a disaster.

The problem with government in Canada is apathy. Nobody, and I mean nobody, cares at all about Canada as an ideal or concept; nobody really cares all that much about their fellow Canadians.
The first phrase in the book is a massive "spoiler".

Well, kidding, sort of.

But no, there are no major spoilers in the article. A few very minor ones. Go ahead and read the book.
> I don't think richer people would think that the government giving $1000 a month to everyone would see that as benefitting themselves, there's your opposition to increasing BI or having it at all.

Huh? No, the point isn't what the richest people would think - they have an incentive to oppose either welfare or cash handouts. The point is that currently, welfare only targets the people with the lowest voting power, because they're both a very small bloc and also a bloc that doesn't vote very consistently in the first place. So there isn't a huge political incentive to increasing welfare.

As soon as you make that a handout that targets everyone (or appears to target everyone), you've suddenly put the largest voting bloc - those who are neither very wealthy nor on welfare - in a position where they will start to clamor to increase it more and more, because they'll see that as money flowing towards themselves.

A ruthless public?

In fact, in order for anonymous art to work, the creator MUST have faith that the public will be motivated to act on a good idea, an insightful summary, a powerful display, or any other call to action that speaks specifically to the people who are tired of being cast as a "ruthless public"

Red-meat reduced diets are likely much more efficient, especially grain-fed cattle. Animals that graze well on rocky, nutrition-poor land like goats or that can be raised in small plots lots goats, chickens, and crickets can have far less impact.

Primarily, though, I'm saying that the biggest impact isn't the raw amount of land being used by animal agriculture. It's the amount of productive cropland that's not being used for human crops but for animal feed. If your goal is to eat the crops directly, then feeding the same grains humans eat to cattle is counter to that goal.

Regional indicators (two of them compose to a flag Emoji) can make many Unicode operations inefficient. For example in the grapheme cluster segmentation it should pair two regional indicators [1], so with a very long run of regional indicators it is impossible to partially apply the segmentation (which is often the case). There really should have been two pairs of regional indicators, the first used for the first letter and the second used for the second letter---just like surrogate pairs.

State analysis: Portions of Wisconsin's Foxconn law could be unconstitutional
What he refers to is that you have to ask for them explicitly:

import numpy as np
arr = np.array([1, 3, 7, 5, 4, 3, 1, .100])
maxval = arr.max() # 1st pass
minval = arr.min() # 2nd pass

Whereas with numba you'd have something like this:

from numba import jit
@jit
def maxmin(arr):
maxval, minval = arr[0]
for e in arr:
if e < minval: minval = e
if e > maxval: maxval = e
return minval, maxval

And that will get optimized to numpy-like speeds, but with a single pass over data. So for large arrays, you'll get about 2x speedup, since memory access is the bottleneck.

As for optimizing this use case for NumPy, I'd go for a cythonized maxmin() function. Which is pretty much the same numba does, but you're moving the compilation overhead from the JIT into the compiling step of the module.
