While that’s true, how many of the devices in use in the wild by regular people have newer versions of Android available? With that in mind, I think the article makes sense.

"Business is about more than extracting the most you can."

Um - no. Certainly not once a company is publicly owned or where the focus of the board of directors shifts from focusing on how to be the best company doing whatever we are doing to maximizing "value" for the shareholders. Once the focus is on the shareholders instead of the core business that core business starts to be talked about as a commodity and its value is its cash flow not how good it is at the business it is in. cf: Virgin America.

Regarding the issues with Wells Fargo it may be some stay "because the competitors are just as bad" but may also simply indicate how entrenched the services Wells provided are to the company. Things like credit card processing, loans (which you can't just switch easily), lockbox services and so on. I know from personal experience there's no problem with the folks having to interact with the bank referring to them in highly negative terms all the while that interaction takes place.

"Unhappy customers is bad for business." Really? That's why Comcast is having such a hard time? Why it's facing so much opposition to the micro monopolies it creates and perpetuates? No one likes Comcast. OK, that's a bit broad. I do not personally know anyone who likes Comcast and I know a lot of folks, including myself personally and professionally, who have been and are customers.

They use the 3 tarrif pricing model BTW: you pay the monthly fee for your basket of services which include some amount of unit transactions and an overage when you bust your limit.

I like a pod cast called "Make me smart". The folks who run it have a question they like to ask at the end of interviews: "What's the one thing you thought you knew and found out you were wrong?" I'm 63 and started my first restaurant when I was 21 and my second when I was 23. I thought if I worked as hard as I could, was fair with the people I dealt with, produced the best product I possibly could while keeping costs in check and charged a fair price everything would be OK. I was wrong. For better or worse I held on to my ideals instead of adapting to the realities of business.

It looks to me like the focus of being in business has shifted from business as a way to be better/bigger/faster at whatever the bussiness does to simply being a means to establish a cash flow and sell to a larger business. I don't know if that's inherently good or bad but it certainly looks and sounds like the new normal.

So, from what I see, business has indeed become about extracting the most you can as fast as you can from as many as you can.
“Mobs” vs. “Crowds”
Even then... Where are you going to start in reading references? A random syscall or function a day? I think it is far more useful to e.g. read the late W. Richard Stevens' Advanced Programming in the Unix environment. It puts everything in context, provides historical background where necessary, and gives examples.

Reference pages are not really for brushing up, but more for the 'what was the address family field of sockaddr called again'-type of questions? Or put differently: they are external memory.
Btw, people are doing lots of arbitrage with crypto currencies as well if you weren’t already aware. It could be a fun way to play with it without spending much if you’re interested.
Out of curiosity - do you work in the US, and are you am hourly or exempted worker?

Here's my problem: I try to maintain a good work life balance. I devote time outside of work to passions, hobbies and relationships. But I am not dogmatic about hours. My company does not pay me to have my butt in a chair. They pay me to get the job done.
What a strange reply. Assuming it's in good faith, what makes you think his reply was trolling?
Looking at the patent landscape of 3D memory [1] I don't really see the issue that Intel would be facing. First of all, as a chip maker they seem to have completely withdrawn from the base level science in memory in the first place, which probably hurts them from getting favourable patent deals - but this seems to be a management level blunder, maybe an overreaction to the Pentium 4 proprietary RAM flop.

In any case it would IMO be better to just now license 3D memory at market cost rather than just sitting on the hands and let HPC markets fade away.

Remember, it has historically only taken 8-10 years for HPC developments to scale down to people's pockets - it could well be that the next iPads outperform what Intel can offer as x86 based laptops, which will not be a good look for software developers deciding which platform they should choose for the next potential killer app.

With big quantities, BOM cost becomes the overriding factor.

It's the reverse of the web dev scalability argument. In web dev, you go for high abstraction and divisible components because it's the only way to handle more requests per second while keeping the software flexible.

In hardware, to scale the business, you need to keep BOM cost low. To do this, you must use cheaper (smaller) hardware and specialize the software to fit. You need to eliminate abstraction and keep the software as tight as possible. Even bootup time matters -- 30 seconds for Linux to boot adds $1 of manufacturing floor time per device.

Linux adds massive BOM cost, and once you're shipping more than 5000 devices per year, it's usually worthwhile to eliminate it.
Not checking work e-mails or IMs while not on the clock should be the standard practice anyway.
The only bad thing about the Moscow metro is how loud the trains are entering and leaving the platform. When I was there, I had to cover my ears while admiring the architecture.
Oliver Sacks (in The Man Who Mistook His Wife for a Hat) also tells a great story of a blind patient with Cerebral Palsy that was so babied that she never acquired use of her hands. She had been carried everywhere and had everything done for her. She called her hands "useless lumps of dough". At 60 years old he and his team managed to get her to use her hands; she ended up going through all the infant stages of hand use. Despite being 60 and never having used them she was able to become a sculptor, feed herself, etc. He thought it might be a one-off but he ran into another patient with a similar situation (babied, unable to use his hands his entire life) who also acquired the ability to use them.

There is a reduction in neuroplasticity with age but there is more and more evidence that it is a smaller reduction than once though and a lot of the supposed reduction is due to attitude, expectations, and technique.

There have also been fairly recent studies with kids and adults born blind who receive surgery to correct the problem later on in life. Not being infants, they don't naturally learn how to build up a system of vision. It was long thought that acquiring vision after early childhood was impossible but that turns out not to be true either. It requires intense therapy to walk the person through the infant stages of learning: detecting shapes, matching colors, learning about edges, inside vs outside, recognizing people vs objects, learning faces, etc. Eventually reasonably decent vision can be achieved. We appear to be primed as infants to learn these things automatically so we never really think about how much work it is.
On the other hand, Firefox seems to have such feature built-in.
It's not a metro line (U-Bahn), actually. It's a railway (S-Bahn), similar to "Moscow Central Ring". Moscow is currently developing it's own equivalent of S-Bahn in addition to the metro.
When there's a willing buyer and seller, aren't they both responsible for the consequences of the transaction? Blame is not zero-sum.
Profiles were introduced in 4.2 on Android, if I recall, almost 4 years ago. Most Android devices in developed countries are above this version. My original Nexus 5 had them, and that's some 4 phones ago.

I'm sure you could find a shipping device that lacks them, but not from a major carrier in most of the world. Of Play-enabled devices, Google puts this at less than 5% worldwide
That is in my opinion an overly simplistic way of looking at it.

First of all, many people (myself included) would not want to have to burn electricity in order to offset the increased price. Even if you disregard the obvious environmental reasons, people sleeping close to their computers simply do not have the choice of leaving it running 24/7 unless they want to have vivid dreams about vacuum cleaners every night.

Second, even if the higher prices can be evened out in the long run from mining, this forces people to pay more money up-front in both hardware and electricity. Buying gaming equipment suddenly became an investment.
Sales and use taxes are purely creatures of state or local law.in the US, excluding a few specialized federal taxes on products like alcohol and gasoline. The federal IRS has nothing to do with that. And if the structure is defensible in court, neither would the many state or local tax authorities.

I always call this quiting the natural way (cant afford it)

While it is a joke I did see plenty of people turn financial "freedom" into their personal hell of drugs and/or gambling.

The weirdest example was an extremely hard working self-employed construction worker with a large variety of skills. The most happy period in his life (from my perspective) was when he lived on a camping in a tiny tent with a budget of 5 euro per day. All he did was eat fruit, lift weights, sit in the sun and chat with the camping folk.

At a different times he had 20 employees. Every day he smoked 2 packs of cigarettes, 5 grams of weed and god knows how much cocaine. But that was during work. He spend all of his free time gazing at slot machines. At the time he also never showed up for appointments if they didn't involve large amounts of money. He owed everyone money that he could easily pay but just didn't show up to do. Great way to lose friends, borrow as much as you can then pretend it isn't important enough to pay them back.

Yet another Make hater; it's disgusting how many wannabe programmers misunderstand Make and then embark on some unholy crusade to kill or replace it.

And then we end up with garbage, toy build systems limited by the programmer's understanding of what the build system should be capable of. After suffering through several of those toys (never by my own choice), I don't ever want to find myself in a situation like that again.

Learn Make, truly learn and master it; don't just claim that you do! It functions the way it does for several reasons! Buy the O'Reilly book (on original Make, not the GNU Make version); go through the examples; UNDERSTAND THEM. And stop trying to build unnecessary replacements. There is enough garbage in the world of software already. Way too much in fact.
If the windows and the HVAC aren't talking, you end up trying to heat or air condition the outside world. This is both futile and expensive.

Also, it takes about eight trees to absorb the CO2 emitted by one human. The contribution of houseplants is tiny. Especially since they usually don't get full sunlight.
Anecdotally, it seems to me that restaurants that want to serve these small plates that I think he's referring to, have moved to tasting menus where a number of of these small things are combined with one or two more substantial dishes.
That's exactly what I meant. The 20% who immediately jumped straight into the MDM rollout are the ones who do not have the concept of "not at work." They have two modes: working on e-mail and sleeping.
I thought it didn't work either but it works extremely well on [some] 13-14 year olds.

The smokes are kept behind a counter here to prevent theft. I buy a pack from a 14ish year old supermarket employee/girl. She turned around to get it, gazed over the packaging looking for the one I ordered, then she looked away, her head sunk between the shoulders and she made a face as if she just saw someone eat a baby. Took her a good 4 seconds to get back her senses and face the wall of death for a second trial.
Ask HN: Remote workers, how do you show your work?
When I was working remotely as a dev, I found one of the hardest problems was communicating what I was working on with my team.

My parents always taught me to be modest when speaking about myself, and to let my results speak for itself. However, I found that in a team environment, proactive communication works much better.

How do you share your day to day with your team? What tools, methods, or habits do you use to solve this problem?
Pardon me if I sound vulgar, but could it also be perspiration?

Going to work in an office not completely fresh smelling often attracts more opprobrium with women than with men.
HFT is best defined as predicting movements under a tick; everything above a tick is out of HFT territory. Latency requirements could still be pretty serious though, as many models at many firms can act simultaneously for longer frequencies as well.
Why is light slower that way?
I doubt you'll need one. It's typically a concern when sqft/person is < 80, as is often the case in open-office plans and classrooms.

Ok, so you want to get a new BMW. If it is a lease, that may be $500 or $1000 or whatever per month. That's after downpayment of $many, will be more without downpayment or trade-in or whatever you got.

BMW throws in a cellular connection ("BMW assist" or whatever they call it) for $0, for the first X years. Not sure how many.

You can also get carplay, free for the first year (I think)
But then after that, carplay will be like $80/year. That is <$7/month. How does that even register, never mind make any difference?

And what is the narrative here, like "Oh, I was looking at BMW and Audi; I bought Audi because of the BMW's price-gouging $7/month fee!".

Did that ever happen? May be, but it just does not compute. Far as I can tell, if you are concerned over $7/month, you will not be buying a new BMW or Audi. It just does not add up.
Do you know why Columbia can't just legalize drugs in a meaningful way?

Because US won't let them.

Source: Obama Administration (http://www.nytimes.com/2012/04/15/world/americas/obama-says-...).

I imagine if Obama was opposed then anti-marijuana Jeff Session is super extra opposed.

Do you know why Columbia can't just "stamp out the cartels"?

Because US spent billions helping Columbia do just that and they failed. For decades they tried every tactic you can imagine: destroying crops, military raids etc.

The definition of insanity is doing the same thing and expecting different results.

By that definition trying to stamp out cartels by force is insanity.

We know you can't do it.

Columbia has as much chance of destroying cartels as US has getting Americans to stop doing drugs.

BTW: the really bad violence in Columbia started when US pressured Columbia to create a law allowing extradition of narcos to U.S. Escobar started a wave of violence against the government trying to pressure it into eliminating the law.

Let's not be naive here: Columbia agreed to US demands because US was even bigger threat to them than narcos.

My point is not to argue that Columbia has no part in the mess.

But I would assign much bigger part of the blame to US.

US was an architect and a sponsor of Columbia's failed war on cartels. A DEA agent participated in the raid that killed Pablo Escobar. US Special Forces were training Columbian anti-drug army. US supplied military equipment and billions of dollars to be used to fight drug lords.

Failure to eliminate drug trade in Colombia is as much U.S. failure as it is Columbia failure.

US, not Columbia, spent last 45 years championing failed drug policies internationally.

We won't have meaningful change until most countries legalize drugs and most countries won't do it unless U.S. also does it.

All roads lead to Rome. Or in this case Washington, DC.
I should have done that as well. I hate paying for that fucking CarNet trash from VW., but it is the only way to pre-heat my car... which is fucking insane. I can't preheat the car by physical access to the car, no, I have to do it with a stupid fucking app that works only 50% of the time for 90 EUR a year.

It has been more than once that I actually enabled pre-heating using that fucking app from within the car. I just want the car to remain warm when I grab groceries #ultimatelazyasshole
Is there that much of a performance difference, though? In your example the btree of the index of the 2 years of data is probably 1 level deeper than that of an individual month. If you're mostly querying the last month, only that part of the btree will be kept in memory. The size of the hot data of the index is similar in both cases. I fail to see how that would make much of a performance difference.

For bulk operations like (auto-)VACUUM, CLUSTER or dumping/restoring data it can make a big difference, though.
unlikely to be linked... increasing cache or writing better algorithms will make things faster...

Many industries are held back by lack of interoperability, rather than raw computer power.

One easy rule is use CP when One of these are true.

You need to know the actual optimal answer (metaheurisitics can never prove they have the optimal).

You need all solutions to your problem.

Your problem is just true/false, not optimisation, and there is no obvious way to measure the quality of a partial solution (so metaheurisitics will struggle).

In general, CP does better on smaller, harder problems.

Coincidentally, I started reading Narcoland: The Mexican Drug Lords And Their Godfathers by Anabel Hernández last week, and although the writing is a bit scattershot, it’s quite an eye-opener. I’m only 1/4 through it, but so far, the level of detail is shocking about precisely how deep rooted the corruption is (or at least was until the mid nineties, which is where I’m at now) inside the Mexican government and simultaneously how invasive the interference is from the US government.
