It's a long read, but the gist of this article is "use the right tool for the job". Redis is really good for some things, but in its current implementation, distributed locking is not one of them.

Along with the author of this blog post, I would recommend the usage of Zookeeper if you have a need for obtaining a lock in a distributed environment. You can read an analysis of how Zookeeper performs under a (intentionally) partitioned network here:

Nope, not at all. If I took half of all your wealth, does that mean you'd now be completely poor? No, you'd be poorer and it will harm you.

Even though the poor in India will eventually get Internet (let's hope so) now they will get Internet a lot later and a lot fewer of them would it.

I was lucky enough to get Internet access during the 1990s in India, but there are so many people I wish had Internet. I don't expect them all to become techies like me, but I definitely think it will make their lives a LOT better rather than waiting for the government to do something.

This is what government's services gets you (it's a link to a Hindi comedy show from 1990s which satirizes how many years you had to wait to get a telephone line).

All solid points. The 'what is Lanes' tutorial is being improved right now, as a little too sparse on the detail.

Thanks for the comment.
And... That's why statistics alone don't paint a very accurate picture.

The culture of the midwest varies a lot from state to state.

In many ststes like Colorado, New Mexico, and Arizona white and Mexican cultures are pretty consistently intermixed. Most of the hispanics are second or third generation Chicanos who grew up in American schools and primarily speak English. Basically, Caucasian and Hispanic family makeup is pretty much indistinguishable.

Outside of the major metros (ie Detroit, Chicago), citys don't have inner-city ghettos like you'd find on the East/West coast.'

In Colorado, the suburbs that are almost all white, upper middle class consist mostly of Californians who left Cali for cheaper property and a higher standard of living. They are, by no means, representative of the local culture.

I'm not sure how you came to the conclusion that more homogeneity causes less inequality. Maybe in terms of cultural homogeneity.

The opposite is true in areas where strictly racial homogeneity is the norm. In cities like Detroit and Memphis neighborhoods could be clearly and easily separated on racial boundaries. Racism is rampant on both sides.

As for Black people in the midwest. I didn't live close enough to the city so I can't really say one way or another. The black families that live in the suburbs are clearly the minority in terms of numbers and apparently in terms of culture. The black families I've known from the suburbs usually have good, stable families, and their children do as well or better in schools than the norm.

Of course, I'm speaking in terms of the western mid-west. The demographic of, say, Iowa will be dramatically different. Likewise, St. Louis it will be dramatically different in a completely different way.

Trying to assess the US statistically as one whole is like trying to measure all of Europe as one country. There is a lot of cultural variation between the different states and people generally migrate away from areas that lack a culture that they identify with.

But that's them. I want to develop ES6 in my browser natively and offer my app to people with modern browsers. I don't care about those stuck in the past. Why don't the browsers support it? Browsers support WebGL today where i can run advanced 3D graphics in my browsers. Government workers on Netscape 4.7 won't be able to run but still the browsers have that. Why not ES6? Surely webgl is more complex to implement...
There's no basic accountability in the private sector either. Money does not necessarily flow to people who provide social value - if this were the case, a number of extremely scummy, value-destroying industries would not exist.
I'm up voting this based mostly on the author's reference to Meatloaf songs and PEBKAC in his headings.
As the other poster said, there's a lot of variation in "suburbs" in America. I recently lived a township in northern NJ, which effectively was a "suburb" in the NYC metro area. There was a convenience store just down the street (a 1-minute walk away), a high school right next door, a small river and a park a few minutes away, a "downtown" area less than 10 minutes' walk away, etc. A bug stop at the end of my little street took me to Manhattan in less than 60 minutes. If I wanted to go to other nearby towns, however, I needed a car because the buses were too slow, though a fair number of (poorer) people did use them for that. The houses were really close together and typically quite old; mine was built in 1930. Heating costs were high though because those old houses aren't well-insulated (and that house had been renovated with new windows so it wasn't too horrible, unlike some others). There were lots of sidewalks everywhere, though they tended to be in rough shape in places because of all the salt in the winter; they had to replace them a lot.

I also lived in the Phoenix metro area for quite a while. That was totally different. No shopping within walking distance at all, if you were lucky there might be some kind of park near your development, but older neighborhoods usually didn't have that. HOAs were commonplace and horribly run. There were sidewalks everywhere, but they were only good for walking around the neighborhood to get some exercise, not for actually going anywhere. Any place you might want to go required a car, and public transit was really awful. There were buses, but they tended to go to major destinations, and suburban housing developments weren't among them.

Honestly, I think we'd all be a lot better off if we had much higher-density housing with mixed commercial/residential areas so it was easy to walk to nearby eateries and convenience stores. The problem is the rent prices are always much too high, and I'd like to see some kind of political action to deal with that. I suspect the culprit is a combination of real estate speculation and insufficient supply caused by zoning laws.
I'm sorry you got downvoted. I've nothing to do with the people who make this toilet, or those who plan to sell it, or the site the article was published on (except of course that I'm a regular reader) so if there is some attempt at viral promotion I got nothing to do with it.

I don't see the article as patronising, but then again I don't live in Africa.

Also, for what it's worth, until recently I didn't fly. I'm an immigrant, living and working away from home; when I went home for the holidays I'd cross Europe by train and boat, which took me three days (and cost more than flying btw). I've had to relent recently, because I just don't have enough holidays time anymore :(

I really hope I don't just believe any old bs, but how should I know? I mean, if I did believe any bs, I wouldn't know it was bs, would I?

>>Facebook wants to pay for some bits by attaching the economic value of future customer, and that is fundamentally a justified thing.

Facebook realizes there is very little value they can add to whatever they have done so far. So now the only way to be safe from competition is to create a monopoly and prevent others from even getting a chance from competing with them.

Blockchains can be tampered with, but they're tamper-evident. Sure, a government can 51% attack Bitcoin and lower its value. The value of Bitcoin doesn't matter. What matters is the ability to reach consensus on a sequence of events. Such attacks only make that harder temporarily.

There's no observed instance of such "earlier repair," it's just an invented "hypothesis." Only the non-linearity is observed, and not even by majority of the experiments. The explanation for the observed non-linearity is that the single impacted cells simply have time to die (or be targeted by the white cells) at low levels, whereas at higher dosages there are enough cells for cancer to progress more often. It's just the game of probabilities at the levels at which we have enough noise (low enough doses).
That's not problematic at all. If I want the thing to run, I'll whitelist it and move on. Constant false positives would probably be a bad thing, sure, but any user advanced enough to be installing a keylogger deliberately is probably advanced enough to know the difference.

The alternative is that we don't see when a keylogger is being installed non-deliberately, and that would be worse IMO.
I heard* that all smartphones/cellphones are inherently insecure because:

1. By design, the cellular radio controller (called the baseband) accepts important/privileged commands from the cell tower. (For example, "update firmware". Sometimes, there's even "read range of bytes from phone's internal storage".)

2. Portable fake cell towers exist (called Stringrays).

Therefore, unfortunately, it seems unreasonable to claim that private keys generated by this eZing app never leave the phone.

In principle, I agree with you. However, in practice, a lot of what drives non-competes is concerns about poaching. I don't know if non-competes are particularly prevalent in service industries but I'm probably most aware of examples from consulting. I'm not going to defend non-competes but I suspect one of the reasons that they exist is that poaching clients and use of inside knowledge from a former employer are difficult to prove if they're not blatant whereas working for a competitor is pretty straightforward.

> I look forward to the day when we can say HTML5 is so much better (than Flash) for interactive/media content on the web

That depends on the kind of media we're talking about about: HTML5 video was noticeably faster and higher quality on day 1 and Flash never caught up on performance, which is a big deal for laptop users. Even if you're plugged in, having the fans running constantly and still seeing dropped frames is a terrible experience.

I suspect the story is still different for WebGL but the only benchmarks I've seen are fairly old by now.
The way the non-compete is written could bar a Law360 employee from working at any news outlet that covers legal news, in any capacity. Getting a job in another field means switching careers.
He leaves the same comment on every article that could be taken as negative for the climate change camp. In other words, he's a troll.
You are misinformed. There is absolutely a debate about the effects of radiation at very low doses. This is not like Climate Change where there is a scientific consensus. Look at e.g. the 2009 April edition of Radiology, which featured the competing articles,"The Linear No-Threshold Relationship Is Inconsistent with Radiation Biologic and Experimental Data" [1] and "Risks Associated with Low Doses and Low Dose Rates of Ionizing Radiation: Why Linearity May Be (Almost) the Best We Can Do" [2].

Definitely a concept I have been considering and am interested in! But it's not open source! Site claims source will be available for review after beta but that is obviously futile, the devs could make an implementation mistake the very day after review is completed and bork the whole security model.

Cost of Computing Power Equal to an iPad 2 (Visualization)
Sigh... sorry but Einstein had nothing to do with putting satellites in space.

If anything you're talking about the working of the GPS system and even in that case, the effects of gravity are below the error of the device. (clock drifts dealt with via regular ground synch)

The only appreciable effect is the ephemeris calculation which uses relativistic doppler calculations. Unfortunately the difference between normal doppler and relativistic doppler is minuscule at these speeds and are also within error ranges... So ultimately even the GPS argument doesn't hold water..

So... like, go with Jonas Salk who gave away the fortune that was the Polio vaccine. That's a real hero.
You're right, there have been several economics studies showing that poverty causes stress which makes it more difficult to make decisions that are "rational" in a classical economics sense, such as sacrificing in the short-term for a long-term pay off. Searching "behavioural economics poverty" turns up a lot of good articles, here's an overview:

Who wants to host their content in the cloud on servers they don't control?

Who wants to buy a netbook with nothing but Google Apps on them, collecting data to show even more targeted Ads?

Who wants to install Chrome (a closed-source browser) when Firefox and others provide much more transparency and privacy-controls?

Who wants a phone that tracks your location and reports it to World's most powerful AI company at every instant?

Who wants an on-demand-taxi app that tracks your movement inch-perfect, stores your payment and personal information, and keeps the record of your usage till, probably, end of time instead of... well... hailing a cab right off the corner?

Who wants to trust entities that hold your money in their coffers and in return show "digits" on-screen as a proof of presence of "actual" money?

Who wants to fly in giant metal-tubes, over which one has has no control whatsoever-- from who's flying, to what food that would be served, to what kind of hygiene is maintained, to the safety procedures followed, to the transparency into ways in which your baggage is handled, or your booking information, for that matter?

Who wants to drive a relatively smaller metal-tube on roads with other drunkards and addicts? Why are tax-dollars wasted on initiatives that present such grave dangers-- where someone else's mistake ends up costing someone else entirely?

Sure, there's always a real and present danger. You gain some, you loose some.

Every frontier eventually gets integrated into civilization. It's only a matter of time. Civilization brings its laws and its infrastructure and its masses of people. As civilization is bigger than the frontier, the frontiersmen either have to civilize themselves, or move on to another frontier.

The nice thing about the Internet is that it is particularly hard to civilize. It's incredibly hard to wrap laws, which have to be enforced, around information technology. There is always more information than there is people to look at it. So the Internet offers an "endless frontier" of sorts. The Chinese government is famously grappling with this.

Such a thing is not unprecedented, there are plenty of arenas where there is always going to be room for intrepid settlers to voyage to and scrape out an individualistic experience in. Academia is such a place. Doesn't matter how civilized the university gets, there is always room for more people pushing the boundaries of institutionalized knowledge.

We should welcome society into the Internet. Powerful ideas are bigger than even society, so the Internet will forever remain a place where good ideas thrive. It is society that will be changed by the Internet, not the Internet by society. Society will make its settlements, and people fearful of the rough frontier lifestyle will cling to these settlements, but it won't keep them safe from the powerful ideas generated further out.
Sometimes I wonder if, secretly, a lot of governments just know the numbers and the sheer impossibility of tackling climate change with existing technology and have decided to settle for the near-term human civilization collapse scenario. Google's pretty much done that already.
The way the hillary campaign has cynically co-opted the social justice movement is disgusting, but also reveals a lot of endemic problems with our 2016 sj movement. I wish i wasn't at work right now so i could go in depth on these issues in this comment. Suffice it to say the "berniebro" phenomenon is a fabrication.
There is a "debate" like in all areas where there are big money interests. How much of scientists are on "there's nothing" and how much are on the "there's a debate" side?

Linearity in the observed statistics is absolutely not the same as "beneficial." Even if the statistics gets "fuzzy" for low enough doses who can actually claim the real benefits?

Also: the actual dosages matter. The low enough dosages are something where we simply don't have anything to compare to as "full absence". We get some level of radiation all the time. Even eating a banana gets you a little of the radioactive stuff. And we (as animals) get cancer all the time.

I had exactly the same thoughts. It is a great shame to see what the Turnbull government is doing to Australia's pride and joy of scientific research. The cuts have been going on for some years now under the Liberal government and it is having a devastating effect on staff morale.

Computer Scientists in my experience are quite respectful of a number of other fields, including mathematics, most engineering disciplines, physics, even philosophy (logic) and psychology (big in stats), and most recently, biology. Computer Scientists have a "no-bull" mentality, because ultimately the output of their endeavours has to work on an unforgiving and brutally honest machine, unlike economics, where the output need only persuade others in the field, who have a vested interest in perpetuation of credibility of the discipline, leading to the suspicion, by others, of alchemy.
I was coming at it from a US perspective. In the US retail is still dominated by natural monopolies with service areas and captured customers so those costs are low. There is a huge push toward the kind of retail competition you are talking about of course, however, while the growth in the sector is huge the vast majority of customers still behave as captives. https://ei.haas.berkeley.edu/research/papers/WP252.pdf

As for the value chain you are right that I am simplifying but we are on an internet comment board not writing a white paper. However, the simplification doesn't matter. Whether it is vertically integrated utilities or deregulated and unbundled electricity service, the point still stands that stranded costs are overestimated to the extent that they don't account for the fact the netmetered kWhs tend to be high value, are resold at retail, and do not have to be purchased or delivered by the seller. Adding more middleman or more costs just adds accounting wrinkles (and which I think are inappropriate for the forum).

If your point is that the harm is caused by a reduction in aggregate demand then that is a completely different argument.

That doesn't mean developing secure asynchronous messaging apps for smart device platforms is a bad idea (although adopting PGP over libaxolotl seems a tad foolish these days), it only means people should understand their threat model. If your threat model includes an adversary capable of taking over a cell tower or using IMSI catcher, then use a device with no baseband, like a simple tablet.
