比如说,我觉得ultimate goal for affinity reagent development是thermostable,

multi-target platform, tunable affinity under enviromental cue,tunable
density to achieve multivalent interaction.
那么怎么去实现这个目标?我脚的on paper aptamer其实是最好的candidate,但

举例来说,即使袁荃和另外一位新招的楚天特聘教授傅磊相比,也能看出武大化学系在其中有没有猫腻了。

Abstract
Water/solid interfaces are vital to our daily lives and are also a central
theme across an incredibly wide range of scientific disciplines. Resolving
the internal structure, that is, the O–H directionality, of water molecules
adsorbed on solid surfaces has been one of the key issues of water science
yet it remains challenging. Using a low-temperature scanning tunnelling

I am still not used to the regen-on-demand button. It slows down the car too
rapidly. Rapid deceleration costs you energy. every single time, the

consistency are tunable and a piece of data is typically replicated on 3 or
more nodes. There's no single point of failure. If the cluster can work
normally with a node down, I don't think GC pause will have a material
impact.
Again, latency increases with the number of services being hit. 3 9s can
become 2 for hitting 10 services. It's all about setting up reasonable
circuit breaker and graceful degradation. |

it is all about tradeoff, according to CAP。 多数nosql 降低consistency for
availability. |

一顶要黑的,或者白的,也可以是灰色的。一个系统甚至可以黑一块白一块灰一块,但
不会改变任意一块不会同时又黑又白的本质。而一个RDBMS,但凡支持transaction,就
意味着是白的。
如果RDBMS灰了,就不是传统意义上的RDBMS了。

内存泄漏跟 swap 没有直接的关系.
检查内存泄漏可以用一些工具比如 valgrind

Linux 会把 IO read 数据放在系统 cache 里. 所以第二次读文件就可以直接从 cache
里读, 速度就会比第一次快.
search 了一下, vm.drop_caches 是一个 command, 而不是 tunable. 每次写的时候
才做 drop cache
系统内存不够的时候会自动释放 cache |

Here's a good comparison of different NoSQL DBs, obviously there are pros
and cons on different DBs, it all depends on what kind of app you are
writing, write intensive or read intensive. Overall, Cassandra shows great
write performance and read performance with tunable consistency. MongoDB has
great read performance, is closer to SQL DB in the queries, and has better
JSON support.
Personally I feel Cassandra is more flexible but ha... 阅读全帖 |
