Dozens of comments here assume that there is an important difference between reflected light that enters the eye and light shining "directly" into the eye. It's obvious that spectrum, intensity, flicker, and other properties of the light can have an effect on us, but what difference could it possibly make, aside from these factors, whether the light is reflected or "direct"? Why is there an essential difference, everything else being equal, between backlit and frontlit readers?
Unlike the sibling posts, I have automatic backlight turned off and it regularly lasts a minimum of 5 days. On the fifth or sixth night, I charge it over night and I'm back at it.

With respect to "OK Google," more often than not, I find myself in places where talking to my watch would strike me as obnoxious: the office, outdoors, the subway, an elevator. Sure it's quick, but again, a button press or two strikes me as being more effective in those situations. I really would only think of using voice commands in my own home, or in the car. I guess it's all a matter of personal preference... I know exactly how the UI of the Pebble app works, and exactly what it's going to do in a certain amount of time when I press a particular button, which feels pretty seamless to me.

Lest I only say good things about Pebble, I have to mention that in a little over a year of ownership I'm on my 4th one: 3 RMAs due to persistent screen defects. This 4th one should be sent back, too, but I've yet to get around to the RMA process again. Two of the RMAs were within 1 year of purchase, and one was beyond, so my credit goes to their customer service.
I like this primarily because your Cluckles mascot is extremely cool. +5 thumbs up.
Unconsidered Attack Surface for Web Platforms

Is there a better way to prevent malware than a pretty basic review process (iOS/Mac App Store) and data sandboxing?

And to continue the car analogy, lots of car modifications are illegal for safety and public health (smog) reasons. I think computers are headed in the same direction in the next 40-50 years. The children of tomorrow will think it's absolutely bananas that we used to run unsigned code, because malware behaves much like pollution.
101 Motivational Quotes That Will Inspire You to Succeed in 2015
Herb Sutter, one of the most prolific C++ experts out there, recently gave a talk on Modern C++ [1]. In the beginning of his talk, he states that every C++ developer should read a "Tour of C++" [2] by Bjarne Stroustrup, the original designer of C++.

I recently read it and it's great. The book has less than 200p, but still covers the most important parts of C++11, albeit not in great detail (the reader is pointed to "The C++ Programming Language" by the same author for that). Read it! And watch the youtube video in [1].

Definitely.. thanks for the suggestion!
For some definition of easy, I guess.
My point was fairly clear, and the phrasing you omitted turned my argument into a straw man.

The US Government is not a monolith. It is a collection of individuals and organizations acting independently and at odds with one another. This is by design.
I wonder if any of these theologians will ever change the direction of their logic. It's funny that things like this are said, “How could he be God and leave extraterrestrials in sin?”, and not "if there are extraterrestrials, is there really a god?".
What's the point on logically arguing from a position of faith anyway? Doesn't that defeat the point?
Maybe we should just stop believing the stories of people who quite clearly tripped during a fasting high (or similar) in the desert over 2000 years ago.
Motives aren't really relevant here. Reciprocation or replication by others does happen, regardless of motive, so caring for family and friends (or strangers for that matter) is very much in one's self interest. I took issue only with the idea that it's not.
Day 6: Simon Says
This is very interesting, but not as a CPU saving optimization. I'm sure it does that very well, but that's not why it's Important. Rather, this seems to me like the next step toward the inevitable future of PostgreSQL as arbitrarily scalable, and as _the_ general query engine that ties together whatever physical data stores you happen to use.

It seems obvious to me that pushing the Foreign Data Wrapper layer with work like this is how we eventually break through the RDBMS scalability barrier of the individual host. In the future, I'm sure you'll see similar work where _the_ GPU won't be the GPU and the PCI bus won't be the PCI bus. Rather, they'll be _a_ host and the network. A database service (database cluster in Posgres's nomenclature) will eventually run not just on a single machine, but on a single cluster of machines. Instead of a cluster of machines for redundancy, you'll have a cluster of clusters.

Postgres is really two things in one: a physical layer of bytes in pages in files, and a logical layer of queries on tables of records. The most important piece in the future will be the logical layer. The FDW layer will naturally be extended and generalized until it is fully as powerful as the current physical layer. At that point, it can be made THE api through which the logical layer accesses data. The current physical layer will then be nothing more than the default implementation of that general API.

At that point, we can move whole or partial tables to other hosts. Perhaps the autovacuum daemon will gain a sibling in the autosharding daemon. The query optimizer will need to care not just about disk IO, but network IO and will need to start considering the non-uniform performance characteristics of different tables. Some tables will be driven by Postgres's default physical storage engine. Others will be driven by other RDBMSs, or by NoSQL key/value or document stores, or other data stores. They may be on the same machine or a different one.

Postgres will transform into a query engine on top of whatever data stores best fit your workload. I expect the query engine will learn about columnar stores and be able to mix those in a single query with the row stores, key/value stores and document stores that it already understands. PostgreSQL will be a central point through which you can aggregate, analyze, and manipulate any and all of your data. It needn't be intrusive or disruptive: you can still use a normal redis client for your redis store, but you can also use Postgres to manipulate that data with SQL and to combine it with other tables, whole RDBMSs, other NoSQL stores, spreadsheets, web services, or anything else. Maybe it will even make things like Map/Reduce frameworks redundant.

I don't typically follow Postgres's internal discussions, so maybe this is already being discussed and planned. Or, maybe it's so obvious that nobody even needs to talk about it. Or, perhaps I'm just some wide-eyed idealist who doesn't understand the fundamental problems preventing such a thing from ever being practical.
No, a petrol lamp was bright enough to read at night and study way longer than what the sunlight could bring you. I'm not sure what you are trying to argue with - do you think modern society just started 120 years ago only?
Here is a case where the research is lagging the knowledge base. Every holistic MD has, for decades, preached eating foods enriched with healthy bacteria. What we need now is research that looks at outcomes.
I'm surprised there haven't been kickstarters for little robotic bug killers yet. The processors and sensors are getting powerful enough, and within the right power band, that the premise of having a stabby little anti-bug device (a small roomba that kills) is within reach.

Of course, then we'll make them larger. And larger. And eventually it will spell our doom.
Do I understand correctly that there is no refund if a cheaper rate is not found? IMO this sounds really shady.
So, the only thing I'm actually interested is: API for it stays the same? That is it's the same old "all in one" data structure with the same behavior for all standard functions, with all old gotchas left in place and no new added, right?
Ok, good. I was just curious.

(No need for the downvotes HN people, It was an honest question.)
How about TV then ? It's not so popular nowadays but people used to watch TV until they went to sleep, late at night. That was even worse than LCDs or e-Ink backlights.
Indeed. The heaviest demand for bags I've ever seen was on a puddle jumper between Philadelphia and Washington, on a windy spring day.
Thank you, was actually needing a refresh on this!
So far the Moto 360 is the only smart watch for sale that I think I'd want on my wrist. It looks like a cool watch. I don't think I'd use the apps or anything a whole lot, but I think that it'd be a nice enough looking watch to wear around.

I think that tech people are overestimating the potential of wearables as useful tech. There isn't much a smart watch does for you that you couldn't pull out your phone and do.

However, the whole reason smart watches exist is to increase the LTV of a customer. When you are selling a $200-600 phone, selling a $200+ watch is a nice bump in LTV.

Apple's interchangeable bands is not just to make the manufacturing process cheaper and more efficient, it's also to make it so you can buy multiple bands to match different outfits. I know some people who own tons of Chuck Taylor shoes of different colors to match every outfit they own. Same kind of deal.

In many ways, wearable tech is less about tech and more about fashion businesses. Fashion is a great business because it's disposable. Disposable things get repurchased.

Phones are disposable, laptops are disposable, all of it is disposable and that is almost like a form of recurring revenue. Devices as a service in a way. The push for all of this is driven by profit, not by much else.
Ask HN: How to become a chef?
I'm a software developer pursuing a masters in CS after working in the field for a few years. Although I like programming and it used to be a passion of mine, slowly I've realized that I enjoy cooking more. I'm wondering about how to make the transition into a professional chef where I can make a good living - maybe own an artisan cafe or something. Have any of you done something similar? How did you go about doing it? Part-time? Switched abruptly? Chef School? Home training?
I just used this on my repo and that's exactly what it did. It created a PR. I then reviewed the PR, squashed the commits down to a single one and merged it.

It worked beautifully. 10/10 would use again.
British gold bought distractions. Britain has the best navy but on land it couldn't even compete with France. If the French were able to cross the channel from Boulogne, then it'd be the end of the empire.

At Austerlitz, Britain paid money for each dead Russian soldier. English agents were busy counting the dead making sure his majestry's money is well spent while French medics trying to save wounded from both side. Austrian emperor Francis allegedly said 'English are merchants of human flesh.
Its development absolutely was by itself, even if its borders and autonomy were not. In fact, you can probably say that more about North Korea than any other country, given its policy of strict isolationism.
> A Roger Ekirch, author of At Day’s Close: Night in Times Past (2005), sleep had been divided into two distinct segments, separated by a period of night-waking that lasted between one and several hours. The pattern was called segmented sleep

I'd like to dispute that claim (I have read the article) and I had been in touch with people who lived before Electricity started being used and none of them mentioned anything about a two-segment nights (actually refuted it). This may have been the case in certain circles but I suspect this was not a thing for everyone in society.
You could always fork repos to your own robot account, and then do the pull request from there.
Cool, but data are obsolete; for example type "rust" the first one is good, but the second one is the old repo from when it was inside mozilla account with their last know number of starts and when you clic on it you are redirected to the new one, but it probably is because they don't have a stream of updated data and must gather them.
I don't think your explanation makes much sense. Hidden classes describe the layout of objects: if two insertion orders produced the same hidden class, it would mean they have the same layout, with the same fixed field offsets.

The only difficulty I can see with doing that is that is insertion order.
>> "When I watch a movie I always want to see it reproduced as accurately as possible, even at night."

Exactly. I turn Flux off during the movie so I feel that any benefit it would provide me is wasted as my reason for using it is to help my insomnia. It's definitely nice when coding but the major reason for me using it seems wasted because of the movie :)
The dude map: How Americans refer to their bros
Algorithm and Blues (“make” for front-end pipeline)
Reflection off anything but a perfect mirror has a significant effect on spectrum, intensity, flicker, and other properties of light. So, given the limited set of available artificial light sources suitable for inclusion in an e-reader (which limit the starting set of options for those properties before considering reflection), even if there is no essential difference in the abstract between reflected and directly-emitted light in terms of the human effect, the effect of those properties likely creates an important difference between practical reflected and direct lighting in e-book reader devices.

The comments that assert (not "assume") that there is an important difference between reflected and direct light in portable e-book readers largely expressly note that the difference they are discussing is in that context, and neither assert nor assume a fundamental difference in reflected or emitted light in general. If you could make a back-lit reader that simulated a front-lit reader in all relevant features of the light reaching the eyes, it is obvious (tautological, even) that there would be no difference in the effect that light had -- but in real-world devices, "everything else" isn't equal between front-lit and back-lit devices, and the issue here is the effects of real-world devices, not hypothetical devices that exist only in thought experiments.
So, is the Espion headless browser based on an existing one? If this is the case, which one?
Gaining the confidence of the user is not easy:

1) I think you should state explicitly that the compression is lossless (if it is);

2) You should provide some kind of demos/examples to look at.

Good job anyway!
So why are not all Buddhists vegetarian then ?
FreeBSD Foundation Newsletter, December 2014 – Letter from the President
"Bright enough to read" and "bright light" are very different, that's been my point since the first comment. We've had "bright enough to read" for a long time but only in the last 120 years has it been possible to have actual "bright light" late at night.
haha. Really :) ?

I made it and thought it was a bit of fun. Im quite proud to have received a complement about him :)

I also thought the bandana adds a sense of badassery!
I just used it and I really like it. What would I pay for it is a harder question. Recurring charges are more difficult for me to swallow, but I would be willing to pay the equivalent of a few coffees or beers every time I used it.
It would be nice to see a BitBucket version as well. Mainly because I keep my private repos on BitBucket since it's free and then do any open-source stuff on GitHub.
Yep, there are definitely a bunch of ways to do this. A few of the reasons I made this rather than just using a CLI tool:

* Speed - spinning up a bunch of workers to do this can optimize large repos a lot faster than my laptop
* CPU - optimizing images on my laptop can really max out the CPU, turning on the fan, using up battery
* Stats - I've wanted to make reports to send around to the company on the optimizations that were made - was quite hacky to pull this from a CLI report into something that could be shared
Ask HN: Open-Source Pastebin clone, what features would you want?
I'm creating an open-source pastebin clone right now for internal use at my company, we plan to open-source it once it's in a usable state. What I would like to know from HN is what features would you like to see in a pastebin clone? Expiry dates, syntax highlighting, user accounts, etc.

The plan is to make this easily deployable by anyone who doesn't want to expose their possibly sensitive pastes to the internet, they can stand it up on their own servers.
Ask HN: A game about spacetime?
I've been reading Brian Greene's Fabric of the Cosmos, and I've been trying to get my head wrapped around general relativity, particularly the counter intuitive notions of time and space at high speeds, great distances, and large gravities.

I'm not a game developer, but the thought occurred if anyone knew of a game that can help make some of these notions more intuitive?
Yeah, and their alien mythology would be alien-centric just like our religion is human centric.
> I would suggest reading Perelandra

People should read Out of the Silent Planet first, and then Perelandra. The third book in the series is also good, but goes in a different direction and doesn't really touch on the relationship between the Christian God and extraterrestrial life.
That's super Byzantine. Do you guys have a decent test structure? Probably wouldn't have to tip-toe around so much.
The most valuable thing about the article, in my opinion, is its teasing out of the difference between strategy (considering all means and all goals) and tactics, something that -- for example -- the US military might learn from (which defines the difference by the number of soldiers involved -- I am not making this up).

Napoleon was very good at tactics, grand tactics ("strategy" in the US), and even logistics, but he was not good enough at strategy to win. As many have pointed out, the odds were stacked against him because he represented the Devil in terms of the ideas he and the French Empire espoused, and despite his defeat the ideas won.

Ideology aside, most importantly, Napoleon represented a dominant power in Europe which Britain -- at the time the world's only real superpower -- implacably opposed for strategic reasons (unified Europe means Britain no longer top nation).

The thing that really riles up the British about Napoleon is that his influence and fame are so wide relative to that of Wellington, who was if anything a better tactician. Even in this article the emphasis on the Russian campaign for Napoleon's defeat probably irks those who follow Wellington. Wellington defeated the French in India, securing Britain's economic advantages, and then turned Spain into a bloody quagmire. He won every battle he fought, usually with few casualties on his side.

Oh, and he is the one who finally beat Napoleon, despite being outnumbered.

Here's a nice comparison of the two:

No, I was responding to the idea that things have improved in the last 40 years. I am not sure they have. There are some ways in which they have, but in other ways we have slid further back.

> But it's not that slaves were forced into a 'wage labor system' and didn't own property.

Sorry, I was unclear. I am talking about the end of the Civil War and that the wage labor system was billed as the way forward for former slaves, instead of the land reform that Gen. Sherman and others pushed for.

> No matter how exploitative the welfare and even prison systems are, it's still not in the same league.

Define slavery for me. I think the best definition is when someone is compelled under force of law to labor for the profit of another. In this regard having prisoners work on jobs that generate profit for private companies, and penalizing those who refuse with longer sentences is slavery. There is no other real word for it. Additionally, as long as convicted felons are then exiled from the polity (unable to vote, discriminated against in private employment, etc), then you have something while, not as harsh as American slavery before the civil war, is quite a bit worse, in terms of denying whole demographics political and economic power, than Roman slavery was.
I buy my phone outright and then use a different carrier. I have used H2O but recently switched to Cricket. My wife and I each have $50/month plans that include 3 GB of data and unlimited text/calls.

They give you a $5 discount for having a second line and a $5 discount on each for having a credit card on file to auto charge.

Net is $85/month for two. And it's the same network as AT&T (in fact, they are owned by AT&T).
Utterly pointless comment
It's something I may look at eventually, but not a priority right now - Github has a lot more users, and it would increase the complexity quite a bit to deal with two separate systems for permissions, APIs, etc.

Thanks for the feedback though!
I think sandboxing is a quite good solution, but it doesn't mean that you can't have a root access. Consider jails in FreeBSD, where you can isolate a single process but at the same time you have a control over whole system.

Your car analogy can provide insight into the consequences of a single insecure system in the network, but at the same time it's not valid when you consider that you can (should) control your systems and network if it has to fit your needs.
We are not arguing about the same thing then ? My comment was specifically about the fact the day-light cycle had been disrupted for a very long time in human existence already. Not matter if lights were dim, using a petrol light after dark is already disrupting that cycle. Or do you contest that?
Awesome idea, but this should really be a build step, not something people run manually, and definitely not touching the source images.
I also really like the Apple ecosystem, and most of the OmniGroup products are very good (I have used OmniGraffle for figures for many of the books I have written) - I just upgraded my license, BTW.

However, OmniGroup does not support Android (which is reasonable). Comparing my Galaxy Note 4 to friends' iPhone 6+ phones, I think it unlikely that Apple will ever have me as a phone customer. Other companies like Microsoft, Google, Dropbox, etc. support all types of devices very well.
Also of interest to readers: read about lokas [0].

As per the Indian philosophy every gross being has a subtle energy (prana) body [1] which is the same in whichever loka you go after death.

You can experience this subtle form with yoga. It's also said that with years of yoga practice you can master subtle body and you can travel into other lokas in this lifetime with your subtle body (while the gross remains here on bhuloka in the still posture)

Hey, not everyone is in the same timezone!
Image compression is lossless.. I really should call that out on the home page. Demo / examples are definitely on my list.. here's an example PR for you: https://github.com/shrinkrayio/demo-images/pull/6
The work may have been funded by the manufacturers in return for the analysis and discretion.

There's not that many DRAM manufacturers in the world. Micron, Samsung, Elpida, Hynix are all excellent bets.
This seems roughly the same as the monopoly question. Both are seemingly more about enumerating all the edge cases than anything to do with software design or implementation. In 20-30 minutes what do you generally expect to get out of asking this? The benefit to me of elevator over monopoly is that there are inherent issues of safety that dovetail nicely into fault avoidance and recovery and into broader system design and testing.
