Here is what he says about that:
https://boards.openpandora.org/topic/18485-free-lossless-ima...

Decode speed to restore the full lossless image and write it as a png is not so good: about 0.75s for a median file, 0.25s for a p25 file, 1.5s for a p75 file. That's roughly 3 to 5 times slower than the other algorithms. However, decoding a partial (lossy) file is much faster than decoding everything, so in a progressive decoding scenario, the difference would not be huge.

There's still room for optimizing the encode/decode speed, but it's not very useful to do that before the bitstream is somewhat finalized. The prototype implementation I have now is not extremely fast, but at least it's in the right ballpark. Most likely even an optimized decoder will still be slower than an optimized PNG decoder, but the difference will be small enough to not matter much (certainly compared to the time won by downloading less bytes).

Soylent actually has all the nutrients required for an adult human, while Ensure does not. Ensure assumes you eat SOME other food to make up for nutritional deficiencies, while Soylent aims to provide a 100% replacement for all of your meals if you desire it.
> The bus mentioned at fastcoexist appears to be designed for a full-day charge for the entire route, rather than more frequent quick charges during the day.

Which is not that practical because it has to carry all that extra battery weight. There are other american electric bus companies that are cheaper and better than this.

Future eBUSes have to be route configurable, this way it'll be lighter and BMS would be much simpler.
> Some of the guys arrested were in the Soldiers for Jesus Christian Motorcycle Club.

Did you get that from the article, or do you have additional sources? The article had one photo of a Christian biker (or rather, one photo of a biker and the caption said he was with a Christian club). The caption did not say that he (or others with the club) were at Twin Peaks, nor did the article mention them whatsoever. Or did I miss something?

To me, it seemed really odd, like the article was trying to say "see, some of these bikers are really decent people" and imply that some of them were there at Twin Peaks that day, when they really weren't.
This doesn't bug me as much as it might of back in the days when Microsoft was trying to build a closed system with all of their technologies. It very much looks like they are trying to pivot into a platform agnostic services company. Good for them.

Its has very little to do with the tax rate (although the low corp rate does help) it is to do with arbitraging tax law that effectively makes all profits in the EU bar those made in Ireland untaxed.

Just to be clear, it is not that all EU profits are getting taxed at Ireland rates, it is that almost all EU profits are not being taxed at all.
hmm, how could it be? The pixels values have to fit into the eventual reconstructed image. If the values were different than any pixels found in the final image, it wouldn't be progressively loading, it would have several different size images embedded in it.
I've lived my life in Finland. I don't know if the schools are all that (it's been 20 years since mine)... But I can speak for municipal daycare / kindergarten, as I have a 3-year-old daughter and I've been extremely happy with the care.

The teachers and staff at the center are so competent and compassionate. Playing is always at the forefront, but they have educational themes for a full year that are cleverly integrated into the daily rhythm. The children are always doing short trips that reveal new things of their daily surroundings in the city. The social environment mixes children of various ages: there are kids of age 2 and 5 in the same groups.

I know my child's life would be a lot poorer without daycare. And it only costs about 200 euros / month. (We're paying the maximum price since we're two working parents; with less family income the price would go down to nearly zero. Also, children are eligible for daycare even if their parents are not working.)

Giving our kids a rich social life and early education without the pressures of a traditional school model is probably the one thing Finnish society has figured out. (The rest is more or less a mess right now.)
Isn't the word "disposed" more suitable to this context than "susceptible"?

- If you're good at android development - please, PLEASE build a good text editor. It is the most important app for me, the first thing I look for in any new device, and all android text editors suck SO MUCH. I would easily spend $10-$30 if you would build something like Editorial, that would be convenient to use on android smartphone.

-----

- Think if there's something in your life that's missing, some tool that you would like to use, and build that.

- If that fails - think about the perfect niche, about people you like and respect, who use technology and/or could benefit from it; understand them deeply, identify their goals, problems, challenges; and build something for them.

- If that fails - look for a different not tech-related hobby. Like music or writing or woodworking or something like that. Whatever makes you the most curious. That will help you with burnout, and will give you a great niche to work in. Then identify the problems you're facing, and solve them with technology.

- If that fails - talk to other people and ask if there's anything they might need, if there's any problems they have, etc.

- Also - check out new mobile OS'es, like Ubuntu Touch, Firefox OS, etc. These are new, emerging ecosystems, where there's plenty of apps to build. You can simply look at the most successful iOS/Android apps, and copy them to these platforms.
I may try that again... I last tried regular release a couple months ago.. some sites and the ads are so horrible in mobile without an ad blocker... but firefox was way too sluggish.

You can't really trust these press releases in general. A quick search turns up this:

http://pubs.niaaa.nih.gov/publications/arh301/3-4.htm

The gist seems to be that although some groups do have different alcohol metabolizing genes, Native Americans don't differ from the general population, so their alcohol problems can't be explained by genetics.

If you really want to get to the bottom of it, you'd need to spend an hour or two on google scholar.
The CPS boogeyman was hyperbole, yes. Few freerange parents get charged with anything, but a few do still have to deal with investigations or charges by local police. Is it isolated? Yes. But it happens. Even if police don't get involved, you get flak/judgement from neighbors and nosy busy bodies butting into your business and trying to parent your kid(s). That happens a lot more and is something most any free range parent in a suburb knows the feeling of.

The fear is there and my father had plenty of issues with busy body neighbors and the police being called because of an "unattended child" (me). The shit happens and my own mother is one of the judgmental busy bodies herself; looking down on her neighbor for letting their 11 year old child to play jump rope with her friend in the front yard of their house. Has my mother called CPS on the neighbor? No. But she treats them like shit and refuses to let my sisters' visit their house in fear they'll do something "unattended".

Yes - those two examples were very personal anecdotes. But it's not like I'm the only person to ever deal with this stuff. A great thing about the internet is you get to meet countless other people who have the same issues you have:

http://www.freerangekids.com/why-do-i-keep-scaring-people-wi...

If the US didn't have a culture of fear and nosy busy-bodies butting into other peoples' business at every turn, this wouldn't even be a discussion and "free range parenting" wouldn't even be a term. It would be called "parenting". Like how it is in the UK, Japan, and many other countries.
I rather like this line of thought:

On a tangent, many cities currently limit population and job densities in areas to keep vehicle traffic at a manageable levels. Except that is based on the supposition that, no matter what. people are going to travel by cars, or maybe that being able to own a car and to use it is a basic right. In fact, people have different ways of getting around, and those without cars are even forced to find other ways of getting around. So if you want to limit vehicle trips to avoid congesting the road network, instead of restricting population/job density, why not restrict vehicle density by restricting the number of parking spots available? That way, you can restrict vehicle trips without actually restricting development unduly.

At one time, I was pursuing an Environmental Resource Management degree with intent to later get a Master's in Urban Planning. I gave up my car some years ago. I think we do need to start questioning our autocentric assumptions in the U.S. in order to make other options more viable for people who don't want to be joined at the hip to car culture.

If you go into a health food store like whole foods, there's a dozen or so other meal replacement options very similar to Soylent. Some soy free, some with exotic herbs and algae, some high protein, and all within the same price range.
Seems like the mistake the author is making is announcing something as a "product" when it's really still a "project."

In principle, using the GPL license for the reference code is OK if his intent is to encourage other people to build more refined, practical, and performant implementations. But the real problem with his choice of license is that a lot of people can't even look at the code for fear of tainting themselves legally. Given that there is no desperate market demand for a better-PNG-than-PNG, it wasn't a good idea to handicap the proposed format by saddling it with various restrictions and legal minefields.

If the reference code is strictly of proof-of-concept quality, which it sounds like it is, then there was no reason not to use a more permissive license.

I think most exponential backoff schemes I've looked at treat the 'backoff delay' as a range and do randrange(0, current_backoff) or similar which does what you say.

Truncated exponential (where you cap the upper limit of the retry delay to some maximum) is also often a good idea, to prevent a short service outage from spiking the retry timers to crazy numbers.
I was just thinking about this today - have nap rooms with some privacy glass that is opaque enough so the nap room users don't feel like they're in a fishbowl, yet transparent enough so it's obvious when other "relief" action is going on (and the users know it) - and tell the users they're recorded through the glass.

Make sure the room is not unlit though. Daytime naps shouldn't require darkness.
The law makes those kinds of distinctions all the time. For example, when someone dies at work the first thing the government tries to figure out is whether it was just bad luck or the company was being sloppy.
> That stuff happened generations ago so I don't think it's the main reason there is such a drinking problem among Natives today.

NO, boarding schools, forced adoption, forced relocation to urban environments happened within the current generations. Anyone thinking this is old problems has not looked at new from Indian country.

"Having spent some time around Native Americans here are some observations"

I am typing this from a reservation and grew up here. I am a lineal descendant on the tribal roll (not of the tribe I lived with) but missed being an enrolled member by 1/8 blood quota. My Dad is enrolled.

Grouping all of the tribes is as foolish as grouping all of Europe. Dakota have very different behavior than Seminole or Navajo. What you saw is not indicative of all the tribes, but alcoholism is a problem with most. I have never observed the behavior you described. I have observed fights and violence.

Diabetes and Obesity are well know problems and have a lot to do with diet of people who were exiled to places where food would not grow and hunting became scarce. A lot of "Native American" food came from that era and is not exactly healthy.
Couldn't agree more. I think what really made me have a change of hearts was when they started their investments in open-sourcing a bunch of their products.
>A woman with a masters degree in social work assures us that the genetic evidence collected to date is bunk.

Perhaps you missed the whole:

"In fact, there’s no evidence that Native Americans are more biologically susceptible to substance use disorders than any other group, says Joseph Gone, associate professor of psychology at the University of Michigan. American Indians don’t metabolize or react to alcohol differently than whites do, and they don’t have higher prevalence of any known risk genes."

thing.

>Article immediately discarded.

Bias immediately detected.
I think that's a good point.

Though isn't that part of a more complex calculation? Gothenburg already has an electric tram service, which uses a pantograph to connect to overhead power lines. They already have the staff with experience similar to what's needed for an electric bus which charges up at the end-points.

But in a city which doesn't have that infrastructure or experience, or which may have difficulties in getting the rights to install new power systems at the stopping points, it may be more cost effective to use a bus that can be in service for a longer time before recharging.
That's not a big deal but it points to seemingly eternal benefits of being the world's leading power for a time. Americans overlook many of those benefits, I think.

For example, because the Internet and much of personal computing originally were developed in the U.S., the whole world accomodates English and the ASCII character set. If that doesn't seem like a big deal, then imagine if you had to adjust to German, Arabic, or Japanese.

And there is the the UK cashing in on their former dominance again: Because their empire included N. America, the world operates on their language (and a very similar culture).

Or just go to China and see so many people dressing like Westerners, using western techology, etc. Much of what we assume as 'modern' society is western; just think of automobiles and their basic design, for example, or the telephone, TV, etc. Imagine how it feels to see that all your tech was developed elsewhere (which is an unfortunate accident of history and a situation that probably won't last much longer).

Yeah, this is a typical important sounding Verge article that ignores all the research and nuance in the study of Native Americans including some fine research by Native Americans living on the reservation.
From the article:

""Microsoft is enabling players to go in and destroy skyscrapers and everything else in the world. That mode is only possible through the power of Azure, which means Crackdown 3 developers Sumo Digital and Cloudgine are building a cloud-based destruction engine that probably runs on Havok. Once that’s built, and now that Microsoft owns Havok, it could potentially license that destruction engine out to other developers.

What's wrong with people volunteering their time for something they believe in?

How is this any different than developers volunteering their time to a charity or anything else for that nature?

I've done so much "free" work for family and friends, gladly. I struggle to see this any different for those who feel strongly for the Barry Sanders candidacy.
Well, this politician is getting free money from me, which is a step beyond free labor. I signed up to volunteer for his web dev team a couple months ago, but never heard anything back. I guess they (correctly) decided to hire people for that, since it's not an option on his website anymore.
I guess my own position is tainted by the belief that slavery is fundamentally wrong as a restriction of freedom, not as a matter of being beaten. So if I were a slave, though I would personally prefer not to be beaten, I would also prefer slavery be seen as a vile practice, and if I have to take a few beatings to make that be known, I would take them.

The alternate of nobody being beaten, but still being slaves where everybody is waffling and unsure about whether slavery is bad because nobody is being beaten seems to me a bit like a losing proposition. It's the same reason we can't do effective political reform today: people will choose their own convenience when they're not facing a visible evil as a group.

The last thing I would want is for people to think I got beaten because I'm a "naughty slave" or because my owner was a particularly bad guy. No, the reason I got beaten was because I couldn't choose my path. Because I was a slave, and slaves can't choose not to be beaten, even if they would prefer it. When a slave gets beaten, he or she is beaten by slavery as an institution, not by some violent individual.

How much different would the world be if Hitler had announced from day 1 his play to conquer Europe and massacre millions of people? Heck, if we had ended slavery 100 years earlier, maybe we'd be 100 years closer to managing global warming. We don't have time for evils to fester in the margins pretending to be nice.

I remember a couple years ago there was some politician saying we don't need minimum wage laws because companies already pay more than that, so the law is redundant. And in the name of "small government" declared that we should remove the law from the books. All because his favorite corporations are "nice slaveowners" who don't beat their slaves, he thinks that there's nothing wrong with destroying a very important institutional protection.
Why does it matter that she's a woman?

We're getting there. We still have huge problems on the data input side. Standards like fhir might be okay (though limited). Problem is most of the data we would love to analyze is never input as discrete data in the first place. We are far too dependent on the free text note. Also, such data that is available tends not to be available through, say, an API call, as a FHIR message...yet
In addition to what others have said, the transparency of Rosa Labs (the makers of Soylent) is a big deal. Now that they have a manufacturing plant and so on, maybe things will change for the worse in the future, but up to this point they've been very open about their goal to produce a cheap, liquid, easy meal replacement, and they've openly supported the DIY community as well. They've also been adamant from the beginning that it's a process of continual improvement, and that's why Soylent is versioned, almost as if it were open source software.

You could file this all under marketing and not be technically wrong, but it makes a real difference in the experience as a consumer.
In the code I've reviewed, it's not the speed of the db (mysql vs sqlite in-memory, for example), it's the overhead of ActiveRecord itself... tons of ruby object creation, GC, etc...
