Re:CockroachDB 2.0 Performance Makes Significant Strides on Thursday March 29, 2018 @04:23PM (#16710710)
Sure thing. I was primarily answering the question above - in terms of how the numbers in the TPC-C benchmark fit in. I updated my comment to reflect the cost.

I think what's interesting with TPC-C is that you can sort the results based on performance or price/performance. On the price/performance metric, SPARC looks expensive. Dell has a $20K SQL Anywhere cluster that can do 113K tx/min.

I wonder if anyone tried to run these benchmarks on the cloud and how one would calculate total cost of ownership there now.

Re:CockroachDB 2.0 Performance Makes Significant Strides on Thursday March 29, 2018 @04:02PM (#16710557)
I think you can still drive some insights. I clicked on the TPC-C results you shared and read their executive summaries.

The Oracle on SPARC cluster (at the top, 2010) performs 30.2M qualified tx/min vs the 16K tx/min in this blog post. The Oracle cluster also costs $30M, which is clearly higher than the Cockroach cluster's cost.

That said, the TPC-C benchmark is new to me. Happy to update this comment if I'm misreading the numbers.

These features sound great.

On the Data Migration Tool (DMS), I really wish they would fix important issues related to Postgres. Right now, if you have a JSONB column in your database, DMS truncates the data.

This makes it impractical to use DMS for most Postgres deployments: https://forums.aws.amazon.com/message.jspa?messageID=735961

(Semi-related) I'm an L-1A spouse. It took my work application 10 months to get processed, when the USCIS' own regulation stated that the it should have been closed in 90 days.

You call them, ask them, plead with them. Nothing. "Your application is in the system and is getting processed."

Nine months into it, it turned out that they lost my digital picture taken at a USCIS facility. How in this day and age one loses digital pictures is beyond me.

Re:The Most Shocking Result in World Cup History on Wednesday July 09, 2014 @11:28AM (#8010139)
The only World Cup qualifier that I could find (going back to 1990) are the play-off games between Turkey and Switzerland in '06. Switzerland wins the first game 2-0, and Turkey wins the second one 4-2.

Nothing as dramatic as a 7-0 margin as suggested by the article's data though.

Re:The Most Shocking Result in World Cup History on Wednesday July 09, 2014 @12:49AM (#8008115)
Is this data accurate? As a Turkish fan, I don't recall nor can find any records of Turkey losing to Switzerland by a 7-0 margin in 1998.

Edit: Also sadly, Turkey didn't make it to the World Cup in '98.

The link seems to be broken?
Re:NFL players: height and weight over time on Wednesday June 04, 2014 @03:08PM (#7847480)
My guess with NBA players would be that the proportional increase in their heights would be higher.

Does anyone know changes to average weight/height for the population in the US?

Re:Redis new data structure: the HyperLogLog on Tuesday April 01, 2014 @12:52PM (#7509692)
As a quick side note, PostgreSQL had the HyperLogLog data type for a while: https://github.com/aggregateknowledge/postgresql-hll

For people who need SQL and HyperLogLog, we found this extension to work pretty well.

Re:Erdogan says social media 'danger to society' on Sunday June 02, 2013 @07:35PM (#5810530)
If you don't have access to Internet, unfortunately, it does.

I called my mom who lives in Eskisehir Saturday morning TST, and asked her about the protests. Her reaction was, "What protests?" If you get your news from TV, and if none of them broadcast the protests, then how would you know?

Re:Erdogan says social media 'danger to society' on Sunday June 02, 2013 @05:28PM (#5810172)
His actual quote about news spreading through social media is near the middle of the article.

"There is now a menace which is called Twitter," Erdogan said. "The best examples of lies can be found there. To me, social media is the worst menace to society."

In most of the world, revolutions come bottom up. In Turkey, they came top down. It was the military that toppled the "sultan" and established the parliamentary system / Turkish Republic. And later it was a former general who set up the multi-party system (and didn't get elected).

I know it sounds off, but what the Founding Fathers did for the US, the generals did for Turkey. Not a very healthy one I agree, but at least they established whatever form of democracy Turkey has today.

Distributed load balancing is a tough problem with two pieces to it. One is the queueing theory part.

The other is the systems side to it. If you have multiple customers and multiple checkout lines, and if your customers act independently without seeing the lines (no feedback from servers, network failures and delays, implementation complexity), what do you do?

It isn't a trivial problem. The easy route is paying Cisco's load balancers millions of dollars, but those only scale so far.

The bigger internet companies spend years of development time trying to make distributed load balancing work, but the issues there are a bit more complicated than a few customers walking to checkout lines.
