I'll confess it threw me for a minute, but I grinned once I put it together. It's a tad clever, if a bit awkward.
I think the guy is completely wrong about this being marketable - but hey, everybody is entitled to their own opinion and style. I think this is getting a lot of attention right now because it's novel and it obviously wasn't easy mixing it all together. But pull away from that and judge it purely as music - it isn't that great.
I'm sticking to what I know and to the scope of the comment to which I replied. I'm not saying this is a characteristic of just American sports. It is just that I am only discussing soccer and popular American sports.
I have read a good amount about cricket and watched it on t.v. once but couldn't follow it at all. I'm sure there are many sports in many parts of the world that follow similar formats but I can't really discuss them and they wouldn't be germane to the parent post.
I'm pretty sure that is exactly what I said. The only two sports I've seen go super long are baseball and hockey. Basketball sort of but not quite as much as the other two.
Let me explain what I meant by "doesn't work any more". For example a query that originally took 30 seconds now take 3 hours. It still 'works' from a functional perspective but from a business perspective may have become completely useless. Refactoring can make it work again. I should have been more clear on what I meant there.
Chapter 5 - "Statement Refactoring" includes, according to the author, "...how to analyze SQL statements so as to turn the optimizer into your friend, not your foe." It's solid and probably points people towards writing things that work just as you describe.
It discusses how to change client code - which is definitely not database tuning. There are database tuning techniques involved, but really it is much more than that. I tried to express that in the review but maybe I didn't do as well as I would have liked.
Here is how Wikipedia defines refactoring, "Code refactoring is the process of changing a computer program's internal structure without modifying its external functional behavior or existing functionality. This is usually done to improve external or internal non-functional properties of the software, such as code readability, simplify code structure, change code to adhere to a given programming paradigm, improve maintainability, improve extensibility, or increase execution performance."
This book is full of examples on how to do that on the client side and on the database side. When I think of tuning, I think of the items mentioned in the first paragraph of the review - changing db parameters, adding or removing indexes and adding hardware. The book does touch on those but spends more time going over how to rewrite code inside and outside of the database - so I wouldn't say it is just tuning.
I think the emphasis here is on writing the best sql so you can write the best code. Removing unneeded iteration on either side can be a huge benefit. Repeated calls to a database can be expensive - in numerous ways - so I think they aim the reader towards a state where more work is done with less trips.
I think that it is also safe to say that many of the tools they give for testing performance would be very useful in nailing down just where the issue is. It's not an issue of finding what works best - but rather figuring out in each case where the trouble is at.
They don't focus on MySQL - and I don't think the gp (or whatever it was) said they did - but just so it's clear. They do everything evenly between the three. But no - they do not do this for DB2 or PostgreSQL. I don't know how or why they chose those 3 - but that is what they cover. Though I have to imagine much of this will, as in The Art of SQL carry over to any RDBMS.
That's due to a fundamental difference in the nature of soccer and the more popular American sports. When I watch English Premier League I know that there will probably be 10 minutes of stoppage time or so at the most. If it is a draw - that's the end.
Soccer only allows for a very limited set of conditions that actually stop the game clock. (I know it is tacked on at the end - but same difference.) American sports that are timed have a number of variables that can greatly affect the amount of time. Baseball and basketball both allow for practically endless games even in the regular season. Football and Hockey do the same once they move to playoffs.
To my knowledge there is no equivalent in soccer. There may be a small amount of stoppage time and things either end in a draw or a shoot-out. I think these differences make it a little tougher. That said, the vast majority of the time, one can pretty much count on an American sporting event fitting into a 3 hour window. Soccer is usually two right? I've got young kids so they are all too long for me to usually check out for an entire game of anything.
Mod me troll - it doesn't change the fact that it is highly unlikely that there is a fully operational squadron that his friends can talk about but no one knows about otherwise. It makes little sense and so I'm not saying it isn't true - but I really do doubt it. Also the idea that this aircraft would be coming and going completely unnoticed is ludicrous - I don't care how much traffic they have.
I don't think shooting down a Global Hawk would be trivial. Obviously possible, but I think the number of nations that could do it is a very short list.
I think you are right about there probably being something new, and I'm willing to bet there is no human pilot on board.
I understand the reason why aircraft can be preferred to a satellite. But there is no real reason any more for a pilot on a surveillance aircraft. In fact, for the most part the only reason a pilot is in a U-2 is to get it up to working altitude and then get it back down. The performance envelope is such that it is usually on autopilot when working. So really the pilot is just extra baggage and a huge limitation. Something like the global hawk is much better and I'm sure there are/will be much better options coming. The jamming thing is really irrelevant.
Who is still flying them? To my knowledge the last SR-71 flight was 10 years ago or so.
On a somewhat related note, I was watching some stuff on the U-2 a few days ago and I have to think that the days are numbered on that aircraft as well. Between advances with satellites and UAVs, manned surveillance aircraft don't seem to make much sense.
It would have dropped off on its own - now you all have made sure anyone who comes along the thread later will know it was there. Sometimes it is worth just chilling out and seeing where things go.
I know. Check out this discussion I had with my neighbor Bob the other day. me: Hey Bob, was that your mom just leaving? Bob: Yeah, she came over to hang out this afternoon. me:Oh - little hypocritical Bob? Bob: What do you mean? me: Well when that homeless guy that tried to rape and kill your wife came by the other day you called the cops. But you just let your mom right on in and hang out.
I've decided people are just like that - that can't seem to be impartial. They have some crazy desire to take past actions and relationships into account. Weird.
Well - it seems unlikely that this would happen here - but just in case someone comes along and think that the poem or idea is mine. What I have described is taken from the R.A.H. short story Requiem and the poem is by Robert Louis Stevenson. It is a story that had a profound impact on me as a youngster.
It may be better but what you emphasize actually proves my point. What is good and what is popular do not always align.
not if one is a hipster doofus.

It is saying they will be out of a job.
The failed part was designed by a committee using powerpoint.

he's not even that funny. ah well - they'll toss the results and name it whatever they want.

it was the pure amazement of my high school teachers that I was graduating. I was pretty shocked too.

I'd do my job. Then I would find a nice place to sit and look at the earth. At some point a bit of poetry would run through my mind.
Under the wide and starry sky
Dig the grave and let me lie:
Glad did I live and gladly die,
And I laid me down with a will.
This be the verse you grave for me:
Here he lies where he longed to be;
Home is the sailor, home from sea,
And the hunter home from the hill.
