meeting


Tips for getting the most from meeting - http://cn.wsj.com/big5/20120224/eoe082439.asp?source=rss

No meeting should ever be more than an hour, under penalty of death.
Every meeting should have a clearly defined mission statement.
Do your homework before the meeting.
Make it optional.
Summarize to-dos at the end of the meeting.

offshore


Recently I help the company offshore some work to CN developers, many difficulty I've encounter, most difficult one is it is hard to share the vision and big picture to CN developers.

This article mention a few good notes http://martinfowler.com/articles/agileOffshore.html , the one I think I am lacking is having short meeting with them often. I will see if we can have video conferencing so that we are easier to meet.

The other tips here - http://www.theserverside.com[..]_id=45367&asrc=EM_NLN_1439070&uid=703565 but I think the tips list is too long and probably only apply to large enterprise

蒜頭飯 - 閱後傳知他人,添福添壽

一位朋友每天吃蒜頭蒸飯,晚餐用一把蒜頭切碎煮飯, 半年之後高血壓消失了,痛風症消失了,坐骨神經痛亦消失了。 對於目前流行的非典型肺炎,他認為吃蒜頭是增強免疫力的方法, 因為蒜頭是「窮人靈芝」,通血管及清除毒素,以前美軍 亦用作隨身解毒劑。

蒜頭炒飯:
蒜頭越多越香,拍碎,用油鍋炒香蒜頭放入鹽及煮好的飯,加葫 椒鹽拌炒起鍋。 ( 菲律賓人的早餐都是這道主食 )

蛋炒飯,起鍋前撒上一些蒜粉,保證您炒的不夠吃,太香太好吃了。

另一位朋友提醒要多食維他命 C,以增強抵抗力,並切忌吃煎炸熱氣食物,免引致喉嚨發
炎,病毒就由此攻入。

薑湯做法:
1. 約十公克的薑磨成糊狀。
2. 把薑糊放入玻璃杯裡。
3. 注入滾燙的熱開水。
4. 加入一匙蜂蜜,拌勻後飲用。

男女老少都適合飲用。
老薑切片或拍碎煮黑糖功效一樣 , 連續喝兩個月(每天早晚各喝一次 )據書本 記載的見證:
1. 身體變溫暖,手腳冰冷的『怕冷症』體質明顯改善。
2. 體重可減輕約十公斤。
3. 皮膚變得細嫩。
4. 去掉多餘贅肉,腰圍變細。

薑對身體很有益處,愛美又想要健康的人,不妨試試看吧!
祝身體健康!

Note on writing CopyOnWrite wrapper - http://flyingspaniel.blogspot.com[..]ot.com/2010/12/copyonwrite-wrappers.html

Sometime this is a bit difficult for Chinese to be a good programmer, recently some colleague and me discuss about the behaviour of this class and look like we have difficult understanding

A: ConcurrentHashMap support for locking as this is thread-safe
B: ConcurrentHashMap is thread safe for read but not for write because there is no lock, we still need to have external lock to keep it thread safe. By the way, I get ConcurrentModificationException from this before.
C: ConcurrentHashMap don't support for locking but they still thread safe for all operations, which is how "This class is fully interoperable with Hashtable in programs that rely on its thread safety but not on its synchronization details." mentioned.

Too good that we can actually take a look at the source code to see what going on nowadays rather than just guessing - http://www.google.com[..]HashMap&sourceid=opera&ie=utf-8&oe=utf-8 By the way, this constructor is useful for a lot of concurrency access but actually not many developer notice about this - http://java.sun.com[..]rrentHashMap.html#ConcurrentHashMap(int, float, int)

Discussion of encapsulation - http://niket-this.blogspot.com[..]/encapsulation-does-it-really-exist.html

My view on this is that most of the time there's little value in self-encapsulation. The value of encapsulation is proportional to the scope of the data access. Classes are usually small (at least mine are) so direct access isn't going to be an issue within that scope. Most accessors are simple assignments for the setter and retrieval for the getter, so there's little value in using them internally. - https://martinfowler.com/bliki/SelfEncapsulation.html

直覺的奧妙 — Blink - https://thestandnews.com[..]%A6%BA%E7%9A%84%E5%A5%A7%E5%A6%99-blink/

1)  How does the person spend his or her free time?  Per Ayn Rand's observation above, what does he or she do for enjoyment?  

2)  How does the person respond to your successes?  Many people are willing to commiserate with you when you're down and elevate themselves in the process.  A person of genuine goodwill celebrates your successes and is happy for your happiness.

3)  What strong beliefs does the person voice and live through their actions?  Character means standing for what you believe in and living your beliefs.  Go along and get along might be comfortable, but commitment is what powers effective action in the world.

Overview of weak, soft and Phantom References
Second, PhantomReferences avoid a fundamental problem with finalization: finalize() methods can "resurrect" objects by creating new strong references to them. So what, you say? Well, the problem is that an object which overrides finalize() must now be determined to be garbage in at least two separate garbage collection cycles in order to be collected. When the first cycle determines that it is garbage, it becomes eligible for finalization. Because of the (slim, but unfortunately real) possibility that the object was "resurrected" during finalization, the garbage collector has to run again before the object can actually be removed. And because finalization might not have happened in a timely fashion, an arbitrary number of garbage collection cycles might have happened while the object was waiting for finalization. This can mean serious delays in actually cleaning up garbage objects, and is why you can get OutOfMemoryErrors even when most of the heap is garbage.

With PhantomReference, this situation is impossible -- when a PhantomReference is enqueued, there is absolutely no way to get a pointer to the now-dead object (which is good, because it isn't in memory any longer). Because PhantomReference cannot be used to resurrect an object, the object can be instantly cleaned up during the first garbage collection cycle in which it is found to be phantomly reachable. You can then dispose whatever resources you need to at your convenience.

Arguably, the finalize() method should never have been provided in the first place. PhantomReferences are definitely safer and more efficient to use, and eliminating finalize() would have made parts of the VM considerably simpler. But, they're also more work to implement, so I confess to still using finalize() most of the time. The good news is that at least you have a choice.
