Timestamps are not affected by (or aware of) DST. In fact that's one reason why it's so easy to compute the time elapsed between two timestamps. From [0]:

So it's down to the accuracy (and synchronicity) of the clocks used to measure the timestamps: The difference between two timestamps is an accurate measure of the time elapsed (but see below), but that's probably only useful to you if the timestamps themselves are accurate.

However, leap seconds -- during which time passes, but the timestamps typically do not -- and numerical issues stemming from truncation and subtraction do have a systematic impact and reduce the accuracy of the difference. You can address the former for timestamps in the past by simply taking into account the leap seconds; you can address the latter by using higher resolution timestamps, ie. using millisecond timestamps if you need better-than-second-accuracy for the amount of time elapsed.

Software makes assumptions, though most decent time libraries will correctly combine local and date to show the skipped days. It might be a bit lazy though, running "cal sept 1752" will show the same for all locals as far as I can tell from the man page.

On top of that we are all hopefully always learning. New kinds of security attacks will come along and we will have to figure out how to address them.

I would encourage you to consider trying hard to build a team around your project. In my experience open source software is hard work and really only can thrive in a community. This doesn't form magically around the software. It takes time and effort to build. If you can get good security folks in your community you can learn a lot from them.

Object.hashCode() typically returns the memory address of the object, obviously it won't be the same across processes. This should be common knowledge for all Java programmers. The only way to do what the author wants is to define the serialization rules and the hash function the serialized object is fed to. Again, this should be obvious to every Java programmer.

Some folks actually keep their own simple written text notes on what movies they've seen and want to see. same with books, albums, etc. It's free, fast and simple, and nobody has or probably can take that ability away from you.
yeah, I work with text messaging, i.e. "text XXXX to #####" and while I love seeing it places, when I see it on the train I say wtf? But I guess people can draft the message and send it when they go above ground? I wonder if that is the same for QR codes on the train....
Not worth a pull request, but personally I'd replace:

if len(args) == 1:
start, stop, step = 0, args[0], 1
elif len(args) == 2:
start, stop, step = args[0], args[1], 1
elif len(args) == 3:
start, stop, step = args
else:
raise TypeError('xrange() requires 1-3 int arguments')

with:

map = [
lambda args: (0, args[0], 1),
lambda args: (args[0], args[1], 1),
lambda args: args,
]
try:
start, stop, step = map[len(args)](args)
except IndexError:
raise TypeError('xrange() requires 1-3 int arguments')

It's more DRY, and it conveys the intent better.

I would not do such a change to the if step block since its pattern feels noticeably different: "open" checks fit well in a if/else, whereas bunch-of-equalities fit a dispatch map better (plus you can actually modify the map at runtime).
Oh man, I read that article years ago, lost the link and have been unable to find it since. Thanks!

Aren't most pos systems just a touch screen, sounds like the perfect app to deploy on a tablet.

Wastage you get through stock takes, which could be done with a camera (same tablet or a phone), cloud sync so no cradle needed

It could integrate with the latest cloud based accounting systems which their existing pos wouldn't be able to handle (referral $$$), and large companies who have a lot invested in their pos system could pay an employee to integrate it though the apis if they want the search traffic

The biggest problem would be integrating it with the cash tray that goes ding, which I think is desirable I think to stop costumers reaching over the counter and grabbing money while you aren't looking. I guess deploy it as a phone peripheral.

I just wonder if the idea itself has merit. I suppose neighborhoods would specialize more and there'd be less stores with identical stock.

The other opportunity would be advertising to those retailers by suppliers and taking a cut of sales for orders to suppliers, I think that could be where the real money is
That's the key point: measuring results is extremely hard, especially comparing the results of individuals contributing in different ways.

It's cognitively easier for the boss to lean on what is easy (observed time in office). Unfortunate, and like all cognitive biases, we need to teach them, so people can work around them.

There is a big danger to the super cushy corporations: they make work almost as pleasant (for a certain set of vanilla employees) as being at home / out and about. This enables those vanilla employees to happily spend way more than 40 hours in office. Obviously the management must think this is good... but is it?

I suspect the vanilla individuals spending all that time in the office are benefiting from the cognitive bias and are being promoted at the expense of the individuals who have lives. This puts a good chunk of employees who are just as likely to be real contributors into a disadvantaged position.

One could also argue that vanilla employees are less likely to be good contributors, especially if their lack of a life correlates with a lack of interest in new things / etc. This is more of a stretch tho.

Ok, I oversimplified. UTC time does not go backwards, but the value returned by POSIX time(3) -- which is supposed to be the number of seconds since 1970-01-01 00:00:00 UTC -- does. (Assuming you have sub-second precision, of course; time_t isn't required to be an integer type, and there's other APIs which access the same UTC-seconds clock and provide microsecond or nanosecond precision.)

From this it seems pretty certain that the resolution of at least the pro version is 1080p (25:58). And the strong implication is that the RT version is 1366x768, which works out to 208 ppi for the pro version and 148 ppi for the regular version.

"the estimated 10 percent of the game-hungry PC market" that runs Linux

This kind of runs contrary to the popular philosophy that gamers are very unlikely to be running Linux, mainly because the games support has historically always been very bad.

Of course there may be a mass of people who are running dual boots and are just waiting for a load of games to be released in order to delete their Windows partitions (people like me).

On the other hand, I run a dual boot and mainly use Linux as my desktop but since Windows is only a reboot away whether or not a game is available for Linux is not a massive part of my purchasing decision for the game. So it's possible it won't really affect their sales figures.

This surely also brings DirectX into question in terms of it's future as a platform. If I were to develop a game today I would almost certainly use OpenGL for portability reasons even if DirectX was a better library and it doesn't make a load of sense to make seperate DirectX and OpenGL versions.

He keeps clicking here and there to try to restart it, then he clues in that folks can see him doing this and he points it to his chest, card-player style. Then he sprints to the podium to get another machine. I felt for the poor guy.
Extreme process node advantage? They are just one generation ahead at most (2 years). It's not nearly enough to overcome the architecture's inefficiency when it comes to doing GPU stuff, nor is it big enough to overcome the architecture inefficiency for power consumption vs ARM chips for that matter.

Seattle Pedestrian Accident Attorney<p>Pedestrian collisions have lead to some of the most serious injuries that we have seen from our clients here at Premier Law Group. The speed of an approaching car makes it almost impossible for a pedestrian to avoid a negligent driver, and the force of the vehicle makes for a devastating collision. In most pedestrian collision incidents, it is likely that the driver of the vehicle that hit the person is at-fault.

Just How Big Is Apple? [Infographic]
The original 2010 Nature paper coauthored by Wilson (http://www.nature.com/nature/journal/v466/n7310/full/nature0...) received a lot of press when it was initially published, and Wilson's back-and-forth with Dawkins and Pinker got just as much press back then. What Pinker is arguing against is not the initial paper (which he does address in this article briefly by repeating the kin fitness argument) but the claims that Wilson is reaching toward in his new book, The Social Conquest of Earth. Wilson's "press" is essentially this book. The "serious proposal" Pinker is refuting is this book, so this article is essentially a preemptive criticism.

I agree 100%, and actually emailed Maya's parents with an idea of creating an Android Tablet App, and donate a Tablet to them to test/keep. Also created a thread looking for likeminded developers here that would want to help develop such an app: http://news.ycombinator.com/item?id=4107019

If anyone is interested in hacking something cool together, send me an email: sam.granger@gmail.com

They received a few similar emails, and replied to me today. This part was regarding my idea on creating an Android App:

"App design, programming features, and all of the software-related stuff goes right over my head! I appreciate you offering your help---the best people to talk to about tech-related solutions would be the team at Speak for Yourself, who you can reach at this email address: info[@]speakforyourself.org There have been some other similar emails that have come my way, but I've just directed them all over to the SFY team. They would be the best people to ask about whether there are others to assemble."

I did send them an email, offering help, but I doubt they'd be interested since "patents" and a possible lawsuit is probably their current main concern.

To be honest, I don't think creating an app would be all that hard, and to avoid having to speak in thousands of words (which I'd consider to be the dullest part), you'd be able to generate the word sounds through Google's Text to Speech API.

At the end of the day, I hope the App gets accepted back into the store, only time will tell... In the meantime, something open source could be developed in no time.
True, but that depends on what exactly you're reading as a timestamp.

Using localtime in perl for example (a very common method to read the system time) does not return a timestamp, but returns a formatted string (see: http://perldoc.perl.org/functions/localtime.html) that could easily be thrown off by a DST changeover.

1. My understanding is that the user won't have to fumble to launch a reader app (and then aim the phone at, as with QR codes), as proximity to the NFC tag will trigger an event on the phone.

2. NFC tags won't be as efficient if you are tagging individual devices (e.g. all inventory on a store shelf), but for tagging stationary things (e.g. the appliance displays at Best Buy) they will work better, even if they cost a bit more.

lgtt = log --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr)%Creset' --abbrev-commit --date=relative

I almost never user "git lgt" or "git lgtt." Instead I mostly use "git ll", and sometimes "git lg", though if you're doing a lot of merging around, the graph can get a bit convoluted.

By published data, Intel 45nm, with products out in 2007, switches as fast as TSMC 28nm, with products out January this year.

They only have ~2 years of advantage on density, but they reliably have 5+ years advantage on speed. I'd call that extreme.

I absolutely believe that once Intel actually releases atom cpus on their best process (so far, they have mostly used them to fill out production on old processes), it will beat ARM on performance/watt. When they move atom to a competitive uarch (OoO ffs), the race will stop being a race.
For those who don't read the article and follow the link to the meta-bug, those 1500 bugs have been found over six years time and most have been resolved.

Since every change can re-break a test, it's also possible that certain bugs have re-appeared during that time. There's no indication that the bugs found by the fuzzer have become part of the Javascript engine's test cases, but I hope they have.

I think we owe a debt of gratitude to Jesse for the work he's done to make Javascript more robust. Thanks, Jesse

(5) is just a specific instance of the general principle "virtualization screws everything up". The most common issue is with virtualization systems trying to hide the fact that time is being "stolen" by the hypervisor and/or other domains.

(6) is a case of "synchronization is really hard" combined with "benchmarks measure system performance, not system correctness". Most high-performance timing these days involves reading an on-die clock counter, scaling, and adding a base (boot time) value. For that to work on SMP, the clocks need to be synchronized -- and they don't start that way, since CPU #0 is enabled first and does some hardware probing before it turns the other CPUs on. Even worse, on many platforms, power-saving features will slow down the clock, resulting in the counters getting out of sync.

As alexs says, CLOCK_MONOTONIC should be monotonic... but in reality, it's much faster to return a mostly-good-enough value. In FreeBSD, in addition to CLOCK_{UPTIME, REALTIME, MONOTONIC}, we have CLOCK__{FAST, PRECISE} so that applications can choose between accuracy and performance.

CLOCK_MONOTONIC is what I use for timing quite often. I tend to do soft real time stuff and that clock seems the best suited for my tasks.*

As long as you avoid virtualization, turn off all power-saving features, and your "soft real time" can tolerate non-monotonicity on the sub-microsecond scale, you should be safe.
