Rumor has it that they picked ParAccel to provide the underlying tech. I'm curious about how that compares to Vertica and Teradata.
That's a great point. In some ways, couldn't the basic structure of a web page just be a package.json file?

I think between JSON and Markdown, you wouldn't really need HTML. Interesting.
It really makes me wonder why more time isn't spent in making smartphones more durable. People tend to buy them at $100-$200 on contract, not realizing that if they break the phone, they won't get another one for $100-$200. It's more like $600-$800.

Sure, having the thinnest phone made entirely of glass is a really nice selling point in marketing material, but having a phone that lasts the entire term of your contract without needing to be coddled and have the form factor ruined by a bulky case just to protect it is even nicer. For comparison, the Lumia 920 is not incredibly thick or heavy and still looks quite nice, but it can handle an impressive amount of abuse before it breaks:

Have to say that this is pretty amazing. The price is so low that it's a no-brainer to just give it a try. For the same 2TB capability, a Vertica license would run between $20-40K, with high annual subscription fees.

The bigger question for me is why Amazon has been able to figure out the technical details necessary to run this kind of service for this price. It's just ridiculous. Talk about taking the oxygen out of the market...
Basically this. It allows someone (like me) to create something that looks decent even though my natural talents only bring me up to Geocities level of design.
I use Opera for this. It is set to periodically fetch my mails from Gmail and I do not use its builtin mailer to send/receive/read mails (I use the web interface for that), but if I need a substring search then I open the Opera mail search panel and it allows me to dig through my past mail with substring search.

Edit: maybe it is doing prefix search only (I dont' know I search prefixes usually), so it's no true substring search, but prefix search is very useful in itself.
As an NYU student I was inundated with these messages for a bit. I seriously thought about replying to all to give everyone step-by-step directions on creating a Gmail archive filter, but decided it wouldn't really help too much.

> I expect the difficulty to halve.

Why would it? Those who have invested in dedicated mining hardware aren't going to switch it off just because the reward has halved. At least not until mining fails to pay for the electricity that goes into it (but I don't expect that will ever happen.)

Why is my email address under billing?

Does it really matter much? It seems like a logical-enough section to place that field under. I can't think of use-cases where a user would be confused about this unless the company using this tool has primed them to think in certain way about Billing. For example, a company that says "we will never email you billing information" can have its users confused. But that is a made up use-case that is uncommon at best.

Why is the CVC field on a different row?

Again, your question makes it sound like there is a well-accepted standard that it should be on the same row. As an online shopper, I am used to finding the CVC field under the CC field and it has never bothered me.

Why is the year only two digits? Y2K led me to believe two-digit years means accidental ICBM lanches.

That could be because most credit cards list two digits instead of four. And if you have made a payment over phone, it is standard to say something like "0614"(instead of June 2014) when asked for expiration.

Why is it's open source nature to blame here? Can you elaborate?

I just wrote up our experience yesterday. http://orofino.me/antarctica-the-genesis-2/
This is a visualisation tool by the guy who implemented pagemap: http://www.selenic.com/smem/

Unlike existing tools, smem can report proportional set size (PSS), which is a more meaningful representation of the amount of memory used by libraries and applications in a virtual memory system.

Because large portions of physical memory are typically shared among multiple applications, the standard measure of memory usage known as resident set size (RSS) will significantly overestimate memory usage. PSS instead measures each application's "fair share" of each shared area to give a realistic measure.

Here's some history behind it: http://lwn.net/Articles/329458/
Second that.

Ruby/Rails/Javascript/Backbone/Coffeescript - I know I can't be expert and be very fluent all of these stuff, but since I am a full stack developer, when I apply for a job, they ask questions about these technologies and expect me to know these.

I have various previous projects with this stack, and I generally recall while developing new ones, but currently I am trying to get a fulltime job, and now this problem is much more obvious to me. (and kind of blocker too)

I use it mostly for exploratory data analysis. I'm pretty quick with making plots in it (I've used it since v1.2), so I tend to use it for reading in a data set, and them playing around with it. It can handle datasets in the hundreds of thousands of points (still in memory) pretty quickly. You can plot 200k points a series without it slowing down.

On those rare occasions I need to solve equations or do some calculus, there's nothing better.
Another barrier will be the integration with their current "business intelligence" solutions. Microstrategy and Jaspersoft support is a good start, but what about Microsoft, Oracle and SAP offerings?

Switching to Amazon would involve rewriting your ETL process, and retooling your reporting software, and converting all your existing, currently-used reports.

A huge expense in data warehousing projects isn't the hardware - it's the consultants, the time, and the people to support the thing. I'm sure this is a great solution for companies looking to start a data warehouse, or maybe companies looking to revamp their reporting environment completely... but other than that it'd be a hard sell...
In the version we ended up writing, 'operator []' is equivalent to a call to 'Get', which also returns a reference to the mapped value. In the event that key is not mapped, it asserts. If you handle the assert or have disabled runtime asserts, it returns a reference to a static value instance, so you can handle this kind of error yourself or even use the static value as a 'default' (though we never use it that way).

Though not consistent with how STL works, it is consistent with how our containers work and how we use maps. YMMV.

Also, since we wrote it, we're free to change the behavior if a better way manifests itself. So, if you have any suggestions, let fly.
I personally think you are missing the point.

This is not about setting up a big old large laptop a server or using a big old desktop as a server.

Well the important thing is that I'm going to add it now (but I'm having some issues expiring caches) so it may not show up for a while.
You could return a proxy object that offers operator= et al, and an implicit conversion operator to T& or T const& that throws an exception if that key is not in the map.

(I don't know if that would be better, since it's even more magic and it still isn't perfect.)
"It feels like a premium device" kind of grates on me. In most cases, it's code for "it's made of expensive materials that are really quite fragile". Like glass surrounding a rigid metal frame that guarantees it will shatter on impact with no room to absorb a blow.
My bad, I did not read the much more informative BBC article before speculating.

Having a closed circuit nitrogen heat exchanger is interesting because it is a heat exchanger... you still need to get rid of the heat somewhere. For the demo (per the BBC), they evaporated some of the nitrogen to get rid of the heat, but that means you need excess nitrogen to boil off enough to reject the heat. I wonder how they plan to get rid of the heat in a real aircraft.

It also makes me wonder how they can have enough surface area to absorb the heat in the precooler but maintain enough airflow to generate the thrust they would need.
SAGE is pretty cool too! http://www.sagemath.org/
Thanks for your explanations. I didn't get your details but I did more experiments. You may tell me if I am wrong.

1. If my phone has Internet connections, whenever the screen is turn on, the code is refreshed.

If the code is solely based on time, the app may sync its time tick with the server every time when it's turn on.

If the app sends its time to the server, the synced time value should also be encrypted and authenticated. The only pre-shared credential is the 6-digit pin sent by sms, which might be a little short.

If the app gets the time from the server, it might have a slight time delay before the code is computed and shown due to the network latency.

2. If my phone doesn't have Internet connections, the code is only refreshed in ~5s.

So I guess every 5s the app will generate a new code for the next 0~25s.

When the server wants to verify the received code it will check whether it matches with the codes generated in 0s, 5s, 10s, 15s and 20s.

So at least 5 different codes should work in the same time. This may be a nice way.

They detected organic molecules on Mars decades ago, and we are now seeing proof that those who refused to accept the evidence were wrong. I wish I recalled the name of the scientist that designed the test done in the late 80s. He was far more polite and gracious than he should have been. He detected signs that were EXACTLY what they went in looking for in the first place, no one else even proposed an alternative explanation, they just decided to ignore it with pigheaded stubbornness. I hope news agencies dig up the man (I believe he is still alive, he is mentioned in the fairly recent book '13 Things That Don't Make Sense') and they have some of his contemporaries apologizing for going with their hearts instead of their brains.
Hey thanks for posting a known-good result I can follow. I've apt-get updated/upgraded everything and run update-ca-certificates but still no luck. The MTU on our network is 1496 so that almost certainly must be the issue. I'll let everyone know if it is.

Yes, this is a product vs project argument. Products generally have a more intensive and focused effort. On the other hand the scientists which are the main users of Maxima may not be as willing to do or not be as good in development as developers themselves.

In my not so humble opinion and only in my opinion open sourcing of Maxima (or Macsyma) put it in the wrong hands. Not to blame the actual developers of Maxima. Maxima is a very good project by itself just not as good as its commercial competitors.

I think that the sustainability issue can be managed with bloom filters etc, but you are correct. Under the current model where the entire block chain must be in the possession of every client, Bitcoin is not remotely close to sustainable. Imagine if, in order to process credit cards, you had to download transaction data for every credit card transaction in the history of credit cards.

What surprises me is that the original creators, who were obviously very intelligent, didn't anticipate this becoming a problem and create the system from the ground up to address it.

MMA is a fantastic bit of software. It's my secret weapon for lots of tasks, including prototyping algorithms, data manipulation (it absolutely excels at this), visualisation and all sorts of miscellaneous investigatory tasks. I'd love to use it at work but as a Home Edition user my license prohibits this. Were I to accidentally start it at my day job, I'd use it for converting data between various formats, processing it, manipulating it and writing it back again, like a gigantic and insanely powerful interactive awk replacement. Since I maxed out the RAM on my laptop I now have it run at startup so it's always there for back-of-the-envelope stuff.

I used it extensively in designing my side project synth[1], where I used its visualisation capabilities to figure out everything from panning algorithms to delay lines. It earned its keep most often late at night when I was tired and trying to figure out daytime-simple-but-nighttime-hard routines. The Manipulate[] function is really good for this, as it shows you the output of a function as you drag the inputs up and down. I also used it for turning mathematical formulae into C code - the CForm[] function does this very well.

It's also a great way to experiment with functional programming, since that's how it mostly likes to operate.

I reckon there's a lot of places you could use it, but it's too expensive to justify. I don't really care if it's open source or not, but I'd like Stephen Wolfram to have an epiphany on pricing and realise he could sell ten times as many Home Edition copies at a quarter of the price. Its adoption is absolutely held up by its sky high price.

Anyone with further interest in it should check out the Wolfram blog[2] and one of the friendliest StackExchange communities out there[3]

vagrant is a tool for automatically setting up ("provisioning") new vms, according to scripts.

For instance, once you have scripts that download and compile apache, php, python, and perhaps mysql and postgres, you can automatically create a new virtual machine with any combination of those things at any time. Even your applications can be automatically installed in a fresh development environment with a single command. It's great for allowing new developers to get going in their own environment on a team project, and good for you individually, if you have a lot of different things on the go, you can keep them isolated in their own environments and easily setup and destroy them at any time.

The value is adds is great, although it also adds a bit of inconvenience. If your OS likes to update virtualbox a lot, vagrant might suddenly stop working until they update it. Developing the scripts to provision a vm can take quite a bit of time. If you're doing lengthy compiles in the process and those compiles are failing, it can be slow to find out why. Once you get a module down, and it's solid, it's very nice to have.
