Ask HN: Computer glasses – What could a camera+CPU do better than the human eye?
The human eye is pretty good.<p>Here's an example I could see being feasible although I don't have enough domain knowledge. Acquiring natural resources, say mining in a quarry. Presumably a real-time image analysis system could analyze patches of rock which look "promising" to contain valuable materials.<p>Would love to hear plausible ideas for this tech, as well as what anybody else is doing that's making good use of this tech.<p>Cheers

Hot meals in he afternoon also were common in Western Europe, as is clear from the etymology of the word 'dinner' (via the French 'dejeuner' from the Latin for 'breakfast', which was eaten at noon or thereabouts) http://en.wikipedia.org/wiki/Dinner:

Originally, dinner referred to the first meal of a two-meal day, a heavy meal occurring about noon.

[...]

In Europe the fashionable hour for dinner began to be incrementally postponed during the 18th century, to two and three in the afternoon, until at the time of the First French Empire an English traveler to Paris remarked upon the "abominable habit of dining as late as seven in the evening".

India also has hot meals during lunchtime (nice story at http://37signals.com/svn/posts/2882-the-incredible-delivery-...)

I think it made sense to have a hot meal during lunchtime in places where the sun may set early at night because cooking in the relative dark would be more dangerous than cooking during daylight (swaying around a burning stick inside a wooden house to search for ingredients, spare wood, etc, is not a good idea)
I wonder how the delivery service handles out-of-stock items. The Trader Joes I shop at is routinely out of basic items. They told me that they have to restock several times a day, because the store is too small to have much product on the shelves.
If Halloween marks the beginning, then I'm afraid it is not Daylight Saving Time which causes your trouble. Rather, it is DST which alleviates it, and you suffer during periods of "natural" time.

DST is in the summer. And now, in the US, much of the spring and fall as well, since it got moved to November and March. Winter time is "natural" time, where wall time corresponds more closely to solar time.
Yes it's not obvious to me how to impart knowledge in a SRS format that's more than fact recall. I was thinking of starting with thermodynamics because it's one of the more straight-forward equation courses - but then how do you properly do problem solving? I suppose if you walk through a problem broken up into enough chunks phrased as questions, and somehow give users a toolbox from which to choose equations from, it might work.

Amazon Redshift - What You Need To Know
The problem with the 3x approximation is that other expenses don't really scale with rent. If you spend $1000/month on food and $2000/month on rent, and then move to a $3000/month apartment, your food cost isn't going to change to $1500. Sure, the local grocery stores and restaurants might be a little more expensive, but not much.

And $1000/m for food is actually really high. That's if you eat lunch and dinner at restaurants every day and don't worry about the price. Figure $500 for food, $500 for health insurance, $150 for transit... it's not adding up to twice rent.

My interpretation was that sometimes, leaving tasks to balloon from 'C' to 'A' priority comes with a massive increase in cost. In that case it's better to schedule time to deal with the 'C' task earlier.

This is nothing new, of course, and, like any other advice, has to be applied in context.
By area, you might be right, but the big population centers of the US take a big hit. The impact to California + Texas + Floria is going to be pretty gigantic.

And ask people living somewhere that is stereotypically "cold" like Chicago if they want even hotter summers. They will say no.
> Even if that was the case, assuming nothing bad is going on, there has to be a reason all these cases end up there. It's too frequent to be a coincidence.

Fifteen-plus years ago the Eastern District of Texas developed a reputation as a good place to litigate patent cases because at the time it was a fast docket (not so much any more, because of all the patent cases being filed there) and the judges there have come to know patent law pretty well, which is welcomed by lawyers for both sides.

In a 2010 article, Stanford law professor Mark Lemley, who is known for his careful statistical analysis of patent cases (and is cited amazingly often by the Supreme Court), noted that the win rate for patent owners in the Eastern District was 40% [1].

In a 2013 article, Lemley concluded that "... the patent sophistication of the jury pool had no statistically significant effect on trial outcomes." [2]

I would rather live free with 80's technology and free software than live in a totalitarian surveillance state* of 2020's. I simply value free software and the ideologies behind it as a social movement more than I value capitalistic self-centered profit reaping at the expense of end-user freedoms. This also borders the issues with trusting authorities and the whole concept of trust especially with revelations earlier this year, but lets not get there.

Why are you making an assumption that progress couldn't happen without proprietary software? Are you also implying that without copyright we would not have entertainment to enjoy? If so, at all, then our mindsets are the polar opposite. :)

As I mentioned, I've had to opt-out from computer practices which are the norm these days because I disagree with the way they operate. This is a big pain, as I understand their value, however as I value my own freedoms more than I value the conveinience they bring, I am still acting in my best interests here. I wish more people would be willing to make such "sacrifices" to make a point and consider end-user freedom and user and civil freedoms as a more important social issue than what they are considered now. I would see such a world a better place than what we have now.

I see free software as promoting transparency and giving rights, and proprietary software as promoting shady practices without user consent and imposing limitations and reducing rights. This all boils down to reducing the amount of trust and having a cultural and social change to fight against abuse of power and corruption among others. First and foremost it is a social and a cultural thing.

*: Assuming that we get there with current progress and free software doesn't hinder it.

"In early 1982, the Lisa software team was trying to buckle down for the big push to ship the software within the next six months. Some of the managers decided that it would be a good idea to track the progress of each individual engineer in terms of the amount of code that they wrote from week to week. They devised a form that each engineer was required to submit every Friday, which included a field for the number of lines of code that were written that week.

Bill Atkinson, the author of Quickdraw and the main user interface designer, who was by far the most important Lisa implementor, thought that lines of code was a silly measure of software productivity. He thought his goal was to write as small and fast a program as possible, and that the lines of code metric only encouraged writing sloppy, bloated, broken code.

He recently was working on optimizing Quickdraw's region calculation machinery, and had completely rewritten the region engine using a simpler, more general algorithm which, after some tweaking, made region operations almost six times faster. As a by-product, the rewrite also saved around 2,000 lines of code.

He was just putting the finishing touches on the optimization when it was time to fill out the management form for the first time. When he got to the lines of code part, he thought about it for a second, and then wrote in the number: -2000.

I'm not sure how the managers reacted to that, but I do know that after a couple more weeks, they stopped asking Bill to fill out the form, and he gladly complied."

Definitely agree with the "calendar" part. It's hard to create some sort of week plan (or any sort of schedule/plan) with many to-do list types, and it was one of the reasons we developed Thymer back then.

I'm sure not everyone agrees with the importance of a calendar-like component, but it definitely helps to be more realistic about the tasks I plan to do. It also feels like a natural way to prioritize tasks (well, more natural than assigning a random priority number or letter to it, anyway).

Low gravity might be an issue. Given the record on biological processes we thought earth-normal gravity would be vital for, I doubt it, however. I did find one mention of lower fertility rates from microgravity.

http://www.wired.com/wiredscience/2009/08/spacebabies/

But if all microgravity does is to lower fertility, even that's not a problem. 38% of earth's gravity probably won't be a showstopper.
I didn't express that well. Some of the highly creative people who are displaced (or who never show up) are tech people. I'd even say some of the well funded tech stuff is interesting and creative as well.

Background information and context for stuff.

Highlight the best and worst items when you're shopping based on your health, budget, ingredients and reviews.

Highlight stuff you need to buy, no shopping list required because inventory can be taken automatically. This could include suggesting recipes you already have most of the ingredients for.

Social reminders - you met this person at X, discussed y, etc.

Social cues like topics to discuss for awkward people and body language analysis.

Guide you to the nearest bathroom, or your friend, or anywhere else.

Automatically correct for vision impairments. And magnify or zoom out on something.

Allow you to discretely look at anything while talking to someone - read a book, facebook/background checks, boobs, whatever.

To the App Store developers out there: is it even worth getting into this market? I've dabbled in Objective C/iOS development, but never built a full app. Never released anything into the app store. I've been looking for something to direct my free time toward and was thinking this would be it, but I've read an increasing number of articles like this essentially stating that the single-developer part-time app model is dead and you'll be lucky to make enough to pay the $99 to Apple every year.

As a Spaniard living in Chicago, I can't stress enough how AWESOME it is to have the time zone we have in Spain and how much I HATE when Sun sets at 4:30 PM in Winter in Chicago, despite being at comparable latitudes. All my Spanish friends here agree with me, if it was up to us we'd change Chicago's timezone to EST! And also for the other side, sun setting at 10 PM in Summer is Happiness with a capital H. Go ask German or British summer tourists, go ask them :)

If that was true that Spaniards are less productive and constantly tired (which is not, as many of HNers have pointed out) it is not because of the time zone. It's simply because of the toxic work culture that exists in most places, more oriented towards "appearance" of working hard, and that means long hours more than plain simple productivity.

Again, don't get the wrong picture. Most companies in Spain do not have siesta, do not stop three hours for lunch, though 45 min-1 hour is usually the norm and I find it better than having lunch at the desk US-style. The problem is that working from 9 AM to 7 PM is the . If you don't do that, even if you're a top performer, you'd be suggested to "improve yourself", simply because people are envious of your sane working hours. So they say, envy is Spain's national sin.

Ask HN: Have you made a profit mining Bitcoin?
Hi,

I'm interested in hearing people's experience mining bitcoin, especially if you've made a profit.

How much do you have to spend on hardware to keep up with network difficulty these days?

I'm currently considering a Group Buy of 38 330 MH/s USB ASIC Miners, and am concerned about rising network difficulty potentially preventing my recouping what I spend on the hardware: Miners, & Hubs.

I don't have thousands of dollars to spend on TH Miners which would seem to be able to outrun difficulty in the short term.

What are HN'ers experiences mining Bitcoins?

Thanks,

Per SpaceX post-launch press conference: all payloads delivered safely into orbit.

First stage did not land intact. The first burn went OK. The second (single-engine burn braking to the surface) cut off early: the stage spun, and the roll was centrifuging fuel in the tanks. Pieces of the stage have been recovered. (FWIW, this was with the tanks nearly drained. This may be different from Grasshopper, which has ballast to get its weight up and make it easier to control, possibly in the form of extra fuel.)

Next recovery attempt will be on the fourth Falcon 9 v1.1 launch (for space station resupply, after two communication satellite launches).

There was also a problem relighting the second stage after payloads were deployed; they've identified the issue, and will correct. (This would have been an issue for the comsat launches, as delivering them into their desired orbits requires relighting the engine.)

Our governments already pay for software. In fact, they already pay for custom software (you can imagine that large packages "off-the-shelf" need a lot of custom work.) Why couldn't a requirement be that that software be released as libre?

Could a government insist that, if they did fund a next-generation sports car (humvee, armored vehicle, sedan, motorcycle, bicycle) that the schematics and designs of that car be released in a libre fashion? Using libre formats?
The repeated question can act as a sort of propaganda. (See the CO2/climate "debate.") If you know what people will probably say in response, then it would be the civic thing to do to mention it. It would also make it more likely for you to see the alternative answers. I call that "progress."
I agree with much of this essay, but it only hints at a key point: the most brilliant elements of Bitcoin's design are not in the realm of technical achievement, but in the realm of social engineering.

Bitcoin is not just a "technology" but a social platform with built-in incentives for attracting miners and transaction processors, and therefore end-users; growing demand from end-users attracts even more miners and transaction processors -- a self-reinforcing feedback loop.

All other prior crypto-currency efforts failed because, not because they were technically "inferior" (in the narrow sense of that word), but because they lacked the incentives necessary to attract a sufficient number of adopters.
No one forbids you to call into the OS and manually allocate memory.

Oberon family, Modula-3 are two examples of languages with OS that were used in real life situations, although in academic context, for several years.

Native Oberon System 3 and AOS were quite powerful desktop OS for the 90's.

Although I must concede their unsafe package is more powerful than Go's unsafe package.

Anyway, nowadays I personally prefer Rust or D nowadays.
