"Greenplum Database is based on PostgreSQL 8.2 with a few features added in from the 8.3 release. To support the distributed nature and typical workload of a Greenplum Database system, some SQL commands have been added or modified, and there are a few PostgreSQL features that are not supported. Greenplum has also added features not found in PostgreSQL, such as physical data distribution, parallel query optimization, external tables, resource queues for workload management and enhanced table partitioning."

http://gpdb.docs.pivotal.io/4360/ref_guide/feature_summary.h...

Are there plans to eventually have full feature parity with ongoing PostgreSQL development (as in adding features from versions of PostgreSQL newer than 8.2), or is Greenplum going to mostly be taking its own trajectory?
Executing a scheduled call is always profitable, so no. People would just make less money.

The market aspect is more akin to a marketplace where people are hired to do a job. And the job is entirely automatable.

There are a few of these (open architectures) - but does anyone know how much (ballpark) it'd cost to make something like the Raspberry Pi 2 (ie: a full SoC, with gig ethernet, usb, hdmi, sata) support? Say 10.000 units?

I'm assuming it'd be expensive, as it doesn't appear anyone's doing it...

It is interesting to see that even animation studios outsource critical parts of the process to other parts of the world, albeit the last stage of animation after most of the creative process is complete. I think that really does prove how flat the world has become over the years.
Is there some world where demand for scheduled calls exceeds the market's capacity to execute them? And no one has the means or immediate liquidity to switch what they're doing to make a profit off that gap?

I'm just thinking this is really loosely tied system, and it's interesting to think of all the possibilities for how it could break down.

I asked about this today while I was at work.

The gist was: it will depend on a lot of factors, so it'd be unwise to nail any documents to any doors. But watch this space for further developments.

In the mean time, Greenplum speaks the PostgreSQL wire protocol. All the tools that can speak to PostgreSQL can speak seamlessly to Greenplum.

But if you're selling it with the blessing of the owner, what was stopping you from asking "oh, we also need to patch the game so it will run - I assume you don't mind?"

For GOG to sell a game at all already requires that they explicitly cut a deal with the game owner. Fixing the game to run on a modern computer is a trivial part of that deal (and something they already do with their whole inventory).

I'm talking American to Charlotte, a huge US Airways hub. US Airways was just acquired by American making it the world's largest airline.

It's simply demand in the holiday case, but it's still ridiculous. At other times, high demand does not necessary apply and they do all kinds of things to generate demand and compete for butts in seats, especially when fuel prices are low.

But with a high-demand holiday, at a hub almost entirely monopolized by one airline, there is no ceiling to how high they can raise price in response to that demand.

I have to say, when I visited the UK from the US last fall, for the first time with a smartphone, I was amazed at how atrocious the mobile coverage was. I did my research beforehand and went with Vodafone as I expected the best coverage. From the time I activated my phone in Bath, through 3 days driving through Wales, and then up the motorway towards Edinburgh, I got GPRS and EDGE if I was lucky. I think I only occasionally saw 3G and never saw 4G or LTE. I was very convinced that my unlocked iPhone 5s was somehow not able to use Vodafone's faster bands in the UK. It was simply unusable for navigation or even the most basic tasks, and I was very happy with my choice to bring a standalone satnav device as well as the phone.

Then I arrived in Edinburgh, and, bam, 4G -- which persisted back to Newbury and London.

In the US, particularly last decade, we felt that we had been left so far behind in mobile technology compared to Europe, but my coverage woes this last trip made me feel somewhat better-- as did the realization that roaming charges were still a thing in the EU (having assumed they must have gone away ages ago).

The best coverage I experienced was in Iceland, where even the most remote-seeming canyon had top-notch data service, and our apartment for the week had 50Mbps FTTH service.

On a slightly more recent trip to New Zealand, I went with Vodafone again, and had much better luck with coverage-- I only lost coverage on the west coast of the south island which did not surprise me given the remoteness.

This is exciting news. Greenplum's is one of the few instances of a Postgres-based MPP that I've had good experiences with.

The experiences and tuning in the query plan re-writer for MPP might be helpful in rolling in parallel operations support to the base. Not necessarily the "how" since the GP strategy won't necessarily mesh, but the "what".

I agree with the cheap feeling. It seems like they either don't have what I'm looking for or they have a cheaper version. When they do have what I want it always seems to be one of the items that didn't pass QC but wasn't to broken/ruined to avoid selling.
So what's the main benefit of a live system like this? Wirelessly signal players to rebound or not? I guess we don't have to worry about that, it's not like one of the owners is developing this.

> your time is being literally taken from you by others, for their own reasons.

That is not slavery, it's not even close to slavery. And it is not your time being taken away from you, it's your money. One can figure out how to earn money less onerously, then taxation becomes less onerous.

Arguments that modern institutions are basically slavery cannot simply boil down to "the lives of poor people suck". That's always been true, your argument is so general it's meaningless.

States have always survived on institutionalized violence towards its citizens. The question is not of whether, but of what kind. There is no way around violence, we can only try to get by with less of it.

Taxation is much, much, much less onerous these days than slavery was. In fact, Taxation, in the agrarian empires of antiquity, was one step removed from slavery. Ancient peoples had to be coerced to produce an agricultural surplus.

It was basically like the mob. Produce as much as you can and give us 95% of it and we'll protect you from other bands of marauding barbarians. You wanted the people you gave that surplus to to be well-organized and powerful, because that had knock-on benefits.

It was better than slavery because your masters only showed up during harvest. They didn't take your kids and trade them away for a profit. They didn't kill you if you couldn't make quota, otherwise who would work the farm.

Slowly things like social contracts and human rights evolved. Taxation became less onerous.

There is only one obvious issue that could get the masses to fight the anti-privacy bills - the one they usually come bundled with, i.e. copyright. Most people will start to care when you deny them their pirated Game of Thrones or threaten to actually put them to jail for that House of Cards download. Obviously, this is something EFF can't get behind.

Incidentally, what started the huge European movement against SOPA was, AFAIR unrelated, coincidence - the FBI riding Megaupload. Most popular video streaming sites (which were using Megavideo as a video source) suddenly stopped working and the population of Poland went to the streets to fight against SOPA, realizing that the thing is serious. It's amazing how much activism you can get by depriving someone of the next episode of their favourite show.
Edit: There's a shiny website too -- http://greenplum.org/

We (Pivotal, for whom I don't speak in any official capacity) have also opensourced Apache HAWQ (incubating)[1], which is an SQL front-end for Hadoop that was extracted from Greenplum, as well as Apache Geode (incubating)[2] which was based on GemFire.

This was part of a general announcement we made in February that our intention was to opensource our data products as it became possible to do so.

Incidentally, we are hiring engineers across our entire data suite, including PostgreSQL specialists. The Data division solves seriously heavyweight distributed problems. You can look up the listings on http://pivotal.io/careers, or if you like helping a fellow engineer collect a referral, email me: jchester@pivotal.io and I'll work out which office and division to send you to.

Those were special tax deals for special companies. It's perfectly legal to just set a low tax rate, as long as it's universal.
Look like a worthy competitor to Elasticsearch for analytics: it has custom partitioning strategies, true parallel querying, and support for columnar table storage, and has much of Postgres' rich SQL implementation.

The parallel loading looks good, but I'm concerned that the single master means it's a bottleneck for writes -- is this the case, or is there a way to distribute writes across segments without involving the master?

The other concern is that this isn't just "horizontally partitioned Postgres". It's forked from a very old version (8.2) of Postgres, and so doesn't have things like hot standby, streaming replication, the JSON datatype, GIN indexes (does it have GiST?), arrays, etc. It looks like it's optimized for parallel workloads, not for general use.

Anyone here with any experience with Greenplum who can perhaps speak about their work and the things that Greenplum is good at?
I found the framing of the star tracking problem as a graph problem very intuitive. Now I just need a big sounding rocket to try some experiments. :)
But you could probably have bought a half-gallon of Thrifty ice cream at RA for the same price or less as the grocery store. :) You're paying a big premium when you're buying it per-scoop.

I know part of Thrifty's original schtick was being low prices and still high quality, and if they were still keeping in line with that the price would be more like 50¢/scoop rather than $1.79 -- but AFAIK, the ice cream mostly went away after RiteAid bought the original Thrifty drug store and they've only started bringing it back over the last few years, at least in the SF Bay Area.

I do hope they keep the ice cream, though, just on general principle: the bigger retail chains get, the less character they seem to retain. It was sad for me to see CVS buy Long's Drugs a few years back -- Long's stores tended to be bigger and just a little more charmingly eclectic.
This is a concept that doesn't even exist in most other systems, so there isn't an agreed name for it (we call it a "slice" in Spyre). It's similar to a Kubernetes "pod" but not quite.
Except for market saturation. E.g, Walgreens, Duane Reade, and two CVS stores within two or three (short) blocks. Walgreens at 97th & Broadway, Duane Reade at 94th & Broadway, CVS at 93rd & Broadway, CVS at 96th & Amsterdam (which is one block from Broadway).

As far as I can tell, the second quote from the article is incorrect. The lawsuit was not dismissed with prejudice (which is a legal term that means the judge issued a ruling dismissing the lawsuit without ability to re-file).

Instead, there was a hearing on Zenefit's motion to dismiss, the judge indicated during the hearing that ADP's case wasn't going to fly, and ADP "voluntarily" withdrew before the judge issued an official ruling dismissing the case.

Yes, this is what gpfdist[1] is for. Used properly, data can be bulk loaded in parallel across worker nodes without a master bottleneck. I've never used it, but our field engineers tell stories of heroism and victory that typically starred gpfdist as the magic sword.

In terms of what it's good at: really big queries on really big data sets. Note in particular the integration with the Apache MADlib (incubating) machine learning toolkit[2], which was opensourced and donated to the ASF earlier this year.

The US GDP in 2014 was 17.42 Trillion USD while the German GDP in 2014 was 3.85 Trillion USD. So Germany spent more than double what the US did on foreign aid as a fraction of GDP.
I am a sophomore in high school. In fact, I attend the same school as Zach Masterman in the article (Harriton High School), and he is in one of my classes. My one refute to his complaints is that perhaps he would have less homework if he played less games in class. Quips aside, here are my two cents.

I certainly do not agree that all out of class work should be abolished. However, I do think there is a threshold at which it becomes too much. As I presume many of us on this website can relate to, there is lots to be gained through personal study and developing good individual working habits. Many students tend to complain about being forced to go to bed late, however I am willing to bet that many of these students (myself included) sometimes push their assignments back to later in the night and could go to bed earlier with more efficient scheduling. This certainly does not always hold true, sometimes there is just that much to do.

Being a three season athlete I have a little less time than others, however I have found academic success. In general an HN appropriate modification of the "time triangle" (http://cdn1.theodysseyonline.com/files/2015/09/02/6357682979...) has held mostly true:

Pick 3 for the day: Sleep, Academics, Sports, Programming OR Social Engagements

Also, a note about my school. It is in the notorious Lower Merion School District, which is known for collecting lots of money in property taxes from the local old money who send their kids to private school. Thus, they have lots to spend per student (every student is given a new Macbook Air at the beginning of freshman year to rent for 4 years. They receive the exact same laptop every year, to incentivize keeping it in good shape. Only cost to student is $80 insurance deposit per year. The program is extremely successful.), every teacher is paid very well, great facilities, and they perform very well as a school. There is also a competitive academic culture: you are expected to do well at Harriton, and many do. Where homework plays in that equation is unclear, but take it how you will.

My final point is that not everyone who isn't doing homework is sitting around watching TV or playing on their phones. Some have found a passion in something like programming, and actively pursue those passions in their free time (working on side projects, or perhaps even trying to build a company). Our district even provides a mini incubator with small amounts of seed money, free mentorship, and summer office space.

Not to be mean, but this is still all false conjecture and no source. The top 1% earn 19% of income yet pay 35% of all Fed Income Tax. The top 10%, 12% of earned, 12% of paid. The bottom 50% earn 12% but pay 3%.

And thats at the federal level. State income taxes vary from place to place, but nowhere is what you are saying true. And a state would have to apply a substantial effective negative income tax rate for high earners which is laughably unheard of.
OpenCorporates limits you to 500 req/month + hard to download data in bulk (you have to pay) => This is a good example of what Open Data should not be.

Exactly - we really struggled with this. A node (for example, when doing a Docker info when having $SWARM hosts) implies to the user physical isolation. As a distributed systems nerd, I pushed for "anything that doesn't make a contract it's on a different machine". Segment, slice, pod, chunk, block - something other than implying the isolation and therefore fault tolerance of the overall system.

> Would there be more money in it, or is the market already earning as much as it's going to earn, and the used books have no impact?

This would have a pretty huge impact on the publishing industry. Traditional publishers make a ton of money on their backlist – perennial best-sellers like "Catcher in the Rye". These books are great for publishers because production costs are covered and the cost of sale is low (no marketing, book ends, book tours, etc..), and is part of the reason why legacy publishers like Penguin Random House are still such strong companies.

Allowing publishers to completely control the market for these books (no competition from used book sellers) would be hugely beneficial for them; it would make their most lucrative titles even more so.

I'm a little surprised they don't try to do this. They could set up their own used book operation so they can corner the market for their titles.

I think the number of transactions/second will always be reached before demand could outpace the ability for people to execute the calls.

You are correct that it would be an interesting world if somehow demand for scheduled call execution spiked to some massive number that outpaced the ability to execute them. I am having trouble thinking of realistic scenarios where that happens but that doesn't preclude it as a possibility.

It reminded me a bit of how RPG games of old used to have journal entries in the manual, in order to be able to flesh out the story without being limited to a few lines on screen.

The part where I gave up on the story was when you were being told that there's no time to explain anything, yet here you are, inside a hub area and without any urgency at all to proceed with the story line. It felt like they had to explain why they couldn't tell you about the background story with a nonsensical reason.

I've enjoyed the gameplay, but just couldn't be bothered to keep up with the story due to the cards and odd in-game explanations.
This is important. Homework is a poor substitute for class time. If education budgets permitted schools to stay open later in the day, time spent on homework could be spent in class. Plus, the block system is a better approximation of university.
