发帖数: 12072 | 3 Stevey's Google Platforms Rant
I was at Amazon for about six and a half years, and now I've been at Google
for that long. One thing that struck me immediately about the two companies
-- an impression that has been reinforced almost daily -- is that Amazon
does everything wrong, and Google does everything right. Sure, it's a
sweeping generalization, but a surprisingly accurate one. It's pretty crazy.
There are probably a hundred or even two hundred different ways you can
compare the two companies... 阅读全帖 |

发帖数: 1879 | 4 hehe, we were talking about the same thing, although I think that choosing
HashSet is a bad idea.
The reason is that any modification to the HashSet would require this
hash table to be locked. Making modification a time consuming task.
In constrast, a Tree is actually faster since this tree is only growing.
Insertion on the tree node only effect the child nodes. Thus, a tree can
simultaneously handle multiple requests. Comparing to the cost of
synchronization, even for an unbalanced tree, it |

I didn't catch this one. It's good to know. ThreadLocal in 1.4/5.0 indeed has
become a lot of faster. Although I'm still not sure whether it's worth the
hassle, the synchronization issue in your algorithm has been dealt with for
sure.
What about the other point related to the worst scenario performance of
unbalanced trees? |

There are 3 classes. The sample size of these classes are [ 10 12 15]. I

My question is will the unbalanced sample size affect the estimation of

发帖数: 489 | 35 the attached schematic may help explain how the "simple diode" bandgap works.
it is essentially an unbalanced "current mirror". I1 > I2, and Vbeq1 > Vbeq2
. so the output voltage on R3, which is the Vbe differential between Q1 and
Q2, has a much lower but positive tempco.
this is what Bob Peace referred to as the "brutal force" bandgap.
you can run the bandgap much better if you input it with constant current
over the rail, by connecting the rail to a power source with a CCS or simply
with a res |

发帖数: 489 | 36 the widlar bandgap recognized the positive but small TC for delta Vbe and
tried out to lay it on top of a Vbe (which has a negative TC).
so the voltage drop over R2, V2=I2*R2=(delta Vbe / R3)*R2. by adjusting R2/
R3, you can give it a tempco that is "roughly" +2mv/c.
the Vout = V2+Vbe (for Q3), and by trimming R2/R3, you get a Vout that has a
0 TC.
the brokaw design is roughly the same except that it runs both legs of the
unbalanced "current mirror" at the same current - it is driven by a curren |
