Relative timestamps between venues don't matter. More importantly, using timestamps without a common reference point makes it impossible to assert what happened first, because the absolute value of the timestamp does not matter. What matters is what "really" happened first. Of course, everyone's view of "first" can differ, but that's a different issue.

Whether there is signal here or not wasn't my point. There may well could be. My point was simply that the analysis provided by Nanex is spurious without a definition of the timestamps, where they came from, and their relationship to known reference points. Taking three events with a timestamp from each of: CQS, CME, and an arbitrary point in time such as 10:30:00 and then asserting that events observed within a CQS or CME event stream happened "before" the arbitrary point in time, 10:30:00, is impossible.

Unless either (a) one observes CQS, CME, and the event scheduled for 10:30:00 from a known reference and accounts for all variables (differing transit latencies, etc) or (b) each of the generating events are known synchronized and the current state of that synchronization is observable (CQS lags CME by 475us, government event source leads CME by 1.2ms, etc). Clearing (b) is not happening today. (a) can be accomplished by Nanex, if they so choose.

I don't think it's a product of screen size, I think it's more a product of what phone (form factor) you own/started with.

My first smartphone (late to the game) was a Motorola Droid Razr. It's a little smaller than the SIII, but being my first phone, I just became accustomed to the size.

I use friends' iPhones a lot and the first thing I notice (other than just one button) is how small it is. Those same friends struggle with the enormity of my device.

I think it's a similar context switch from Windows <==> OSX. I think people can grow to like either of them, but using one after years of using another makes it seem unwieldy.

I do not understand phablets. I really don't. My Galaxy Nexus is already pushing the limits of what is comfortable to use with one hand, and there is something else that never seems mentioned: Phablets start to get too big for your winter coat pocket, your jean pockets, etc. They simply become uncomfortable to carry, even if you do use them with both hands.

I think we had a few posts from our blog hit the home page.

As we started in Dec 2012 there wasn't too much to show, so no investor contacts etc.

What we did get was a huge amount of great feedback, some monetisation suggestions and offers, offers of free trials for useful products, and plenty of sign-ups to our email newsletter.

The feedback is particularly valuable from this community because the amount of collective knowledge here about technical, business, and design thinking is astounding.
This really sucks. I've always enjoyed the small (compared to those out there now) size of iPhone 4. And now it's just slowly getting bigger and bigger.

Wished they'd ditch iPhone 5 size, but go ahead with the iPhone plus model, this way those that prefer small and nimble devices gets satisfied too (but then not sure how many of us are out there).

I'm all for user choice, but unfortunately "choice" doesn't actually seem to be the way the market is trending...

I've been trying to decide what to do when my phone contract comes up for renewal, and want to stay with the same carrier (phone number, contact email, etc).

However, my carrier (au), despite offering 28 (I counted!) different smartphone models, seems to be going whole hog for giant-screen phones, and the smaller phones are all "budget" models with worse quality screens, heavier weight, etc. [The big exception is the iphone, but I want Android.]

The sense one gets is that they consider smaller existing models "leftovers" from the past, and that they'll be pumping up screen sizes even more once they get the chance...

[This is particularly absurd in Japan where hands are smaller on average, and far fewer people drive everywhere than the U.S. (small size and light weight are more important if you've got to carry your phone in your pocket all day as you walk around; if you're driving portability is a bit less of an issue)...]

they're not replacing existing models, they're adding another option.
Well it's a little more complicated: you should always spend money where the most deaths prevented per dollar are achievable. So if you can save 1 life per $20 spent on thing A, and 1 life per $100 spent on thing B, you shouldn't spend any money on thing B. That's because each life saved via thing B means five people died from not having thing A (net loss of 4 lives).

Why do you think so? This makes perfect sense to me - imperative language wraps purely functional one, and sits on top of declarative, relational language(s)[1] for data storage and manipulation.

The GP is using a very well thought out configuration; this is using the right tool for the job incarnate. If I wasn't lacking in SQL department I would probably do exactly the same (probably replacing PHP with something strongly and maybe statically typed).

[1] SQL and XML seems a bit redundant, but I don't know what they are used for exactly. Also I lumped both SQL and XML together as "relational" because of XQuery, but I admit that I don't know much about the latter and this may be not accurate.

Yes, I think I could have placed more emphasis on the fact that his primary hypothesis is that the conditions sufficient for technological advancement were present in Europe and the Middle East. But absolutely not that there were innate deficiencies in the people who did not benefit from those conditions. He's showing that most of history has been the result of a geographical lottery.

Jared Diamond is a very sensitive and empathetic man, and that really comes through if you watch the TV series by the same name. His work is not at all promoting Euro-centric supremacy as a race or culture, merely explaining a set of historical circumstances.
Maybe Wil Shipley nailed the problem in his "On Being Crazy":

So, is genius linked with craziness? Is this why we aren't all geniuses? Is mankind only so smart because if we get any smarter, we cease to function correctly? Maybe it's just not evolutionarily advantageous to be smarter than we are; it makes us mopey, and we end up cutting our ears off when we're trying to woo girls, which rarely results in offspring.
The term "Phablet" may have been coined to describe the Samsung Note, but that doesn't mean Samsung was the first one who released a large-screen smart phone. The Dell Streak was one of the first, and Windows Phone has the Titan I and II.
Certainly a unique idea.

My only concern is the stigma of this idea will certainly carry over to its purchaser. I, personally, will always have this first impression of the brand as it is currently presented. How can I take this brand seriously in another space, representing a different product or business?

Nature's DNA: The Future of Massive Data Storage?
This is a great question. We start a thread per core, and multiplex thousands of coroutines/events on each thread. When coroutines on different threads need to communicate, we send a message via a highly optimized message bus, so cross-thread communication code is localized. This means each thread is lock-free (i.e. when a coroutine needs to communicate with another coroutine, it sends a message and yields, so the CPU core can process other pending tasks). The code isn't wait-free -- a coroutine might have to wait, but it never ever locks the CPU core itself. So, as long as there is more work to do, the CPU will always be able to do it.

If instead we used threads + locking like traditional systems, we'd have to deal with "hot locks" that block out entire cores. Effectively we solved this problem once and for all, while systems that use threads + locks (like the linux kernel) have to continuously solve it by making sure locks are extremely granular.
I'm of the mind right now that the word "cute" really shouldn't be used in any other context than physical description. It's just condescending and rude.

The problem with your attitude is that it's based upon a premise that is almost never true: that screwups are caused by incompetence, and that they have singular (or overwhelmingly singular) sources.

Neither of these assumptions bear out in reality, and certainly not in our industry.

The vast majority of downtime events trace back to systemic failures, not a freak event, and are more often catalyzed by momentary lapses than long-standing incompetence. Do we penalize the tech who clicked the wrong link on a dashboard, or the guy who wrote the dashboard such that a critical action contains no safeties or confirmations? Or do we penalize the manager for not having any established documentation on protocols surrounding triggering critical actions?

The only reasonable stance here is to collectively take responsibility for the failure. It may feel good to hang someone out to dry, but in all likelihood their failure was only the final link in a long chain of failures that extended well beyond themselves.

You root cause what led to the event (going deeper than "a tech clicked on the wrong thing"), and you fix the root cause, and you move on.
Those two sentences are not a contradiction. I may not be good with reading english descriptions of math, but i am good with applied math. The calculations i did with your numbers disagree with what your graph showed. So to me the graph seems deceptive. There is no contradiction in this.

Further, if you show me the actual calculations done, i will understand it perfectly fine. Yet you refuse to do so. I do not understand why, and i hope you can understand how that makes me even more distrustful.

On the graph in the overview page Perl was shown to significantly outperform Ruby in a number of benchmarks, yes, i could see that. Yet the median of Perl was still set higher than the median of Ruby, which could possibly be explained by perl also being outperformed significantly in one benchmark, but which was not supported by the actual direct comparison numbers.

So i ask again: Please show me the actual calculations performed to arrive at the median values shown in the overview graph.

I have a couple of times found myself inventing solutions to problems I had in the business, only to see them appear as cutting edge open source at the same or a little later (ie Python deployment tools)

I have always assumed one needs to be working in an area, pushing hard and then finding that "what no-one has an answer to this!?" moment.

I would have trouble believing I could find a solution at the cutting edge, and find the people who needed it, without being knee-deep myself.

If all you have to show is a resume and ideas, the above is probably true. You're then subject to all the stereotyping and pattern-matching that VCs are known for.

Many VCs respect traction and revenue though, so going on ideas alone is not the only way.

As for the part about most founders being ex-bankers and traders part, that's not my experience, at least. Nor does it seem to be true of most of the tech founders I read about, although alot of them certainly do bring in financial firepower as their companies grow.
Agreed. The Droid M is about the only recent phone that packs a decent amount of power into a smaller phone- and the fact that I'm describing a 4.3" phone as 'smaller' depresses me.

Seems like a vanity statistic to me. Most companies don't have VC funding so this is to be expected. At least compare this data to prior years.
> In after the 1991 Gulf War, PTSD rates spiked beyond rates ever seen in the US Army.

Last year the [U.S.] Army's vice-chief of staff urged psychiatrists to change the term to "post-traumatic stress injury." Apparently, too many troops come home with PTSI but refuse to seek help. And as a result, some portion of them end up taking their own lives. The Army's hope is that renaming the phenomenon as an "injury" will reduce the fear of being stigmatized [0].

(Apparently some psychiatrists have rejected the idea of changing the name, because heaven forbid that they should alter their sacred naming convention for no better reason than that it might help some people.)

Wow. You really don't know why AWS exists. AWS is Amazon.com.

http://www.zdnet.com/how-amazon-exposed-its-guts-the-history...

As for why, it's easy. Taxes. Much like Walmart rents its stores form an LLC it owns to write off the taxes and bring down the liability of the largest revenue sector, Amazon can write off their server costs since they can "rent" them from AWS LLC. While AWS makes a good chunk of change, it has nothing on amazon.com so by making AWS its own entity (and event better for them that its publicly available) they get a gigantic tax write off and AWS makes capex expenditures saving them taxes. All In all, the shell game must save amazon millions just like it does for Walmart

"Apple seems very confident about the precise size and dimensions of the iPhone display: 3.5 inches, with a 3:2 aspect ratio. Not 3 inches. Not 4 inches. [...]

The iPhone 4 feels like a major step toward an idealized iPhone form factor. What defines the iPhone, physically, is the 3.5-inch diagonal screen." [1]

"On These Rumors of a 4.6-Inch iPhone Display [...]

Sure, developers would get on board and support the new size. But why would Apple want to add another vector of fragmentation? For this reason and others, I say it’s bullshit." [2]

"Regarding a Smaller iPhone With the Same Pixel Count [...]

It’s a physical artifact, and the size of the display is what’s important. [...] I really don’t think we’ll see screen sizes other than 3.5 inches" [3]

"Color me skeptical that Apple would introduce another new screen size of any sort." [4]
