My guess, this is like a loyalty card, but it gives you points for been there rather than buying and it also works on different shops.

If that's the case the way of selling it, as if it is the best thing for your health, its obnoxious. They probably won't care if you walk of drive by as long as your mobile reaches the shop wifi so the customer -the shop- pays.

Location data selling, as other commenter noted, is a real possibility too.

EDIT: After reading the more complete bbc article seems like I was wrong. They say to be using gps and acelerometer data, no idea how it doesn't get hacked to death since both can be faked easily. They also mention that location data won't be for sale. I'm still sceptical.
Note, I'm definitely not a web developer. I've put static web pages together and fooled around with Rails & Heroku a little. So, as an outsider, I'm curious: How did you all (the web development community) make DEPLOYMENT so complicated? All these packages and environments and VMs and containers and environment variables. Shouldn't deploying something on the web be a few minutes of FTP and then go do something more productive the rest of the day? What am I missing?
Uhhhh no.

There is no evidence that LSD is toxic to humans. It is, physically, one of the safest drugs you can take. Mentally is a different story, but at micro doses, you're hardly feeling the normal psychedelic effects that occur at recreational doses, so there's hardly potential for "bad trips". I'm guessing that micro dosing is perfectly healthy.

The only problems are A) knowing what you're taking is LSD and B) knowing what dose you're taking, as you're dealing with an active dose of millionths of grams.
It seems like it's the sudden stop doing most of the damage.
Well, having worked on applications like this, I think it's not totally unreasonable. Of course, could it have been done earlier? Yes. But the backend systems of such applications are usually so complicated and with ripple effects through layers that it takes quite a lot of planning to get it right.

I am not saying delaying a critical vulnerability patch for 6 months is right, but I think airline systems will typically need that much time to plan it well.
I reported 2 admittedly minor web security bugs to them several months back that surprisingly I was apparently the first to report, but still haven't heard back about either.
Let's rephrase your question: "Is six months really unreasonable for an airline to fix a vulnerability that allows customer data to be stolen?"

Yes, I would say so.. especially since this is a 'duplicate' meaning that multiple people were already aware of this, and on top of that it seems the only reason it was eventually fixed was because they couldn't delay fixing the problem any more.

I don't think anyone would consider this reasonable.

On a laptop you now have an extra OS running, with all the associated costs: talking to disk every now and then, doing os-y things.

If nothing else, it feels like my battery runs out faster with docker-machine on and no containers running. But maybe somebody has actual numbers on this?

What are the best sites for freelance Web Dev work?
Now that Elance.com has merged with Upwork.com, I've noticed that the job listings on Upwork.com for ruby on rails developers are rather shotty. They are really cheap, and it's unfortunate because Elance.com was quite good.

What are some other great sites for finding free lance RoR web development work?
The lack of one itself is a datapoint.
In carrots (which are densely planted like four rows to a bed) weeds sometimes do come up in the bed between plants. They usually aren't many because the carrot tops get so dense they smother most weeds out. You can't cultivate those weeds with a tractor (without destroying the carrots) and I don't think they have a roundup resistant carrot. So it's people walking the rows with hoes from what I've seen, or some other herbicide carrots are immune too. The device in the article might be especially good for situations like this.
I guess my question is: why not Heroku?

Sadly the post is very light on important details. For example, which version of PostgreSQL and which kind of indexes? Because GIN indexes do pretty much exactly what he describes as 'tag->id' (but in form that is compressed and very efficient for processing).
Apple sells at a totally different pricepoint which is way off mainstream. So at least atm. they are catering a different market.
Also, smart watches on the market may just be too ugly (including Apple's). I think there's still a lot of opportunity to partner with a major watchmaker like Swatch which owns half of the world's watch brands but doesn't have a clue about the tech.
ElasticSearch is usually less work to install or manage than the average node app – it completely belies the Java stereotypes.

The Lucene-based search engines are also very well optimized. I'd tend to think of a 30M row dataset as a single machine size unless you need failover or the records are quite large.

When your dev teams are strewn all over the world and the lowest common manager with the people managing the OS is the CTO 6 layers up, you will find making things "just work" get exponentially more difficult and all sorts of workarounds and safeguards have to be put in to ensure small changes introduced by other teams do not screw up your portion of the app and vice versa, eg not letting the OS team control the JVM for fear security and performance decisions by the OS team will cause unexpected deployment problems... which will lead to performance and security problems that need to be worked on without OS team involvement...

Of course this is a slippery slope and often devs not familiar with RPM eg end up reinventing the wheel as each deployment failure breeds distrust between teams and more workarounds and safeguards get introduced.
I was used to run Arch Linux, living on the bleeding edge and on the constant moving and packages churning that a rolling release distro provides.

For some months now, I am using Debian Stable on my desktops, and the experience is being very interesting. I don't use any apt pining, and just some packages from jessie-backports (eg: LibreOffice and Intel Video Driver), besides the official stable repos.

This distro is SOLID. My desktop runs very fine, and using a stable distribution means that it will keep running fine for months (years?), instead of that constant discomfort that a rolling release creates as your machine stability and usage potentially changes each day.

Of course, things start to stay a little old, but in the end of the day, it doesn't matter for the vast majority of packages. And you can always compile and install on /usr/local some applications that you need more recent versions.

Oh, they do; but because they target niches, they might be small and not be on your radar. Also, the whole field is still pretty green, in the grand scheme of things; as you say, it takes years to be able to properly leverage the AWS ecosystem.

Once you have the whole system figured out and setup then it seems to be that you have a lot more configuration options and control with eb vs heroku. There might be a steeper learning curve but once you jump the first few hurdles eb does make sense. Additionally, the author mentions deploying a super simple app. Obviously super simple apps are awesome to deploy on heroku because there is nothing out of the ordinary. AWS offers a lot more services for when your application gets off the ground and becomes more complex. It provides the infrastructure and you provide the configuration.

Organizations like that have no code hygiene. They have smart talented people that are entrenched in their way of doing things. They don't have the money to throw the code away and start over. They don't have the control to enforce code standards. There are a couple of terrible effects that slow them down.

I'll bet you a nickel that the json is generated by a stored procedure. In that kind of environment, you can't really run a local version of the system. if you're lucky there's a prod, qa, and development version. the development version is shared by everybody.

What winds up happening is the dev system has lots of in-progress stuff, and i can't release my stuff till the other in-progress stuff is ready to go, or is rolled back.

Also high priority stuff tends to go to "that one wizard guy". Unfortunately that one wizard guy is backed up with 6 months of other projects, cause he's the wizard.

Is it "right"? no, of course not. These systems evolve from people making good decisions in the moment, that don't really take into account the global state of the system.

Finally, every few years a new CIO comes into power and wants to clean things up. a few new folks buy in, but the older entrenched interests just pay lip service, because they know the only way to actually get software out the door is to do it their way. (They tried and were burned by at least one of the prior CIO approaches)

I think those organizations are pretty screwed. they are incapable of change at the layer they need. Banks, schools, airlines, machine shops, anyplace there's a large sized in house dev team (30+), that team is going to very likely kind of suck. There are exceptions, but generally, it's a rough state.

So, yes, i agree, but actually solving that problem in a way that won't kill the business is incredibly hard.

I was in the last class to have the old celestial navigation class. It's not a difficult thing to do. You take a measurement with a sextant then consult a fifty pound book full of tables, get the two closest numbers to what you want and interpolate.

There are various techniques based on time of day and the stars you can see, but if you're not doing it regularly you're going to have to look up the procedure anyway.

And although you might not always be able to rely on GPS, inertial navigation, dead reckoning, and visual navigation using landmarks, celestial navigation has a huge drawback.

It's defeated by cloud cover and fog.

> I.e. do they consider the animal itself dirty, or its inherent genetic structure?

Dirty? That's a really really really bad translation for not-kosher. It has nothing whatsoever to do with cleanliness.

Anyway for the purposes of this meat neither of those two options cover the topic.

The animal itself is what is kosher or not kosher. It has physical signs and those decide if it's kosher or not.

There is a second issue that something derived from something non-kosher is also not kosher.

So CO2 (for seltzer) from beer is not kosher for passover, but CO2 from combustion is, despite both being identical.

But, there is a concept of nullified, i.e. diluted. If someone non-kosher is unintentionally diluted in something kosher at a 1/60 level it becomes nullified and ignored. (So CO2 from the atmosphere is fine for passover even if it originally was from beer.)

Except, if that diluted item is considered "primary", i.e. it's something that even at a 1/60th level becomes important in the final product.

So here we have a single cell from an animal - it certainly is less than 1/60th of the final product, but since it is primary to that product, which could not exist without it, that single cell can not be diluted.

i.e. you have to start with a kosher cell.

A much more complicated question is if it's considered meat with regard to mixing meat and dairy. But the question is academic only since it would be rabbinically considered like meat because it looks like meat and you should not create a misleading situation.

And from the length of this reply you can start to understand why Judaism is such an academic and logically oriented religion with such an enormous quantity of scholarly books. You start with God-given unprovable axioms and generate everything else with logic, one item building upon the next, all ultimately sourced from the Torah (but you need some serious knowledge to be able to trace each law). It's also how Judaism has survived so long - using this method you can extend the law to cover novel situations.
People say Clojure is super functional, but here's an OOP based library. In my experience learning to program with immutability was the trickiest challange to overcome when learning Clojure. I had worked with C++ in college, then js/python in industry for a couple years before I took an interest in Clojure, so I didn't use many const features in C++. Possibly like most programmers, I was used to mutation-by-default.
I can't see how this could be real.

You and others make a good case - my post was to summarize what I ended up doing, as an interesting hack / datapoint - not to slam postgres [ or Redis, or Lucene/solr, for that matter ]

The main takeaway is really how fast SSDs are and how much bang for your buck you can get on a single commodity host instance [ thru some creative wrangling of data structures ]

I will endeavor to followup with a fair comparison using postgres...

The list of companies using Druid in production is impressive considering how recently this project emerged. We’re considering using Druid for our production analytics engine at Tapad (tapad.com). A significant portion of our ad-hoc and user-facing analytics applications involve large, multi-dimensional aggregates over ad impression/click streams, so Druid’s an obvious choice.

So far, mysterious failures when indexing have been major pain point. These seem to be especially problematic with high cardinality dimensions. Has anyone run into similar issues and/or other weird quirks in production? What about real-time avro ingestion?

Best of luck to the Imply team with this project. Whether we end up using it or not, I have no doubt that the Druid + Pivot stack will be a popular choice for folks building analytics products on large datasets.
Which makes you wonder if person #3 or higher submitting this bug couldn't sell it since they are not getting a bounty. Six months is a long time to leak customer information.
The only reason for "reasonable disclosure" deadlines like these is a tradeoff between 1) damage done by disclosing before patch available and 2) damage done by evil actors finding the same bug before disclosure & patch, the assumption being that disclosure will speed up patching.

On the bug difficulty totem pole, this one hangs rather low. Hell, they even claimed it was a duplicate report.

I'm surprised the newspaper didn't run the story anyways, because on a data leak bug like this the work isn't done when you patched the original problem, only when you have combed through all the application logs, identified malicious requests and notified customers and authorities of possible leaks can you claim to have dealt with the issue at hand.

(Yes, if your app server isn't logging all requests, you should probably start today, otherwise you end up like the NSA when Snowden took off and you first learn of lost data when it appears in a newspaper)
That's the exactly way to 'preload', turn the firewall on at boot, 'preload' by running a query and/or reading the index then open the firewall to normal connections.

>Inflation is not caused by money printing.

That is...completely an utterly false. You just disqualified yourself from discussing this topic and be taken seriously imo. Inflation is a monetary phenomena. There is more to it than just money printing, but an excess amount of cash/liquidity in markets is what causes inflation. The velocity of money is also important. Seriously, there's even an equation for this and none of it involves whatever you just said.

This is something that every major school of economics, both left and right agree upon since the 1960s (and it has roots way before then.) I honestly have no idea where you got this idea from. Even Keynesians, who once denied it, now acknowledge it but with their own methods.
