Count That Day Lost

Count that day lost

If you sit down at set of sun,

And count the acts that you have done,

And counting, find                   

One self-denying deed, one word,

That eased the heart of him who heard,

One glance most kind,

That fell like sunshine where it went --

Then you may count that day well spent,

But if through all the livelong day,

You’ve cheered no heart, by yea or nay --

If, through it all

You’ve nothing done that you can trace,

That brought the sunshine to one face -- No act most small.

Then count that day as worse than lost.

an idea for Pak'n Save users to save fuel cost

PknSave fuel voucher is often wasted by their members because their tank is full before it expires automatically. So the idea is, we can share the fuel vouchers through a mobile app.

  1. If it is big enough, you print a voucher whatever you need or not.
  2. If you don't need to fuel your car, post this voucher on our app and set the amount with expire time.
  3. If you need fuel for your car but have not a voucher, open the app and try to find an unused one. When you decide to use it, you booked it so other people cannot use it anymore. If you eventually didn't use it, put it back into the voucher pool.

Sounds great? Let's do it. If you want to contribute to this side project, contact me with [email protected]

麻雀

这些天受疫情影响,我只能在家工作。我的工作台的右侧,就是正门门前的那块空地。平常我们都是使用后院的门,正门极少使用。这块空地就成了麻雀经常光顾的地方。

而我呢,工作累了,或者想偷懒的时候,往右一瞥往往就会看到它们或者在玩,或者在吃东西。虽然并没有人惊吓它们,但我却感到它们不像新西兰别的鸟。那些鸟大多大大咧咧的不怎么怕人,甚至懒得飞,即使你驱赶它们,它们也经常用快跑代替飞。麻雀总是警觉的,不论是吃还是玩,都是玩一秒钟或者吃两秒钟,就赶紧四顾看看有没有危险。我从没有看到过它放松的时刻。

这么警觉的动物会活得很长吧,并不。日日过着担惊受怕的生活,怎么可能长寿呢。查了一下,果然。普通麻雀在野外的寿命也就三年。

可爱又可怜的小精灵啊。

夏时制即将结束所思所想

这是我对看新西兰站长所发文章「4月5日星期天凌晨3点新西兰夏令时结束」的评论。

这意味着对那些不记录 unix 时间戳而只记录本地时间的系统,如果他们依赖时间排序(因为没有时间戳)的话,夜里2点-3点钟的记录会是紊乱的,因为这段时间会过两遍。显示上看起来没有问题的数据,其实是偏离真实顺序的。比如一篇文章的两个评论,明明是后面的评论回复前面的评论,即可能现回复的评论先显示,然后才显示被回复的评论这种“怪事”。当然了,如果用unix时间戳排序会有另一种问题,数据的顺序是正确的,但显示的本地时间却是紊乱的。可能出现显示一个人在 2:45 分发表了一篇评论,但另一个人却“使用了月光宝盒”回到 2:15 分回复 2:45 分评论的“怪事”。

站长说的对,人们应该调整自己的作息时间,而不是调快或调慢计划仪器。但站长说的又是错的,因为人是愚蠢的动物,自律的人是那么的少,如果依赖们自己调整作息时间,节能效果就会大打折扣。所以“调快调慢”计时设备这个看上去错误的解决方案,即又是最管用的方案。世界就是这么奇妙!
