Lies, Damn Lies...

Statistics

Statistics tip: Always try to get data that's good enough that you don't need to do statistics on it - Randall (xkcd2400)

This rings so true. When data points to an obvious conclusion, you don't need fancy analysis to arrive at some hypothetical correlation that may or may not be real. Perhaps the emphasis on statistical tools and methods within the sciences and social sciences in recent decades are a symptom that real progress is hard to come by, and data had to be marinated with statistical sauce to be made to work.

Statistics is also heavily utilized in "big data" as well -- even disregarding the "little data" applications and  puffs-and-smoke buzzwords, it may be true that even "real" big data is somewhat doomed from the start -- sure, you may crunch the numbers and discover that a 2.4% increase in user engagement can be achieved by tweaking some feature, and that often translates well into bottom line numbers... but the crucial question is unanswered -- does it make a better product? Does the user actually benefit?

And thus the old adage: Lies, Damn Lies, ... and Statistics.

Queen's Gambit

It felt like the Cinderella tropes crossed with Hollywood obsessions.

Production and acting was great, but a good story should at least be somewhat believable. Drugs and alcohol and these highly "rational" intellectual pursuits don't really mix. I had a hard time believing anyone, regardless of gender or race, would be able to perform competitively by habitually binging on drugs and alcohol that are well known to dull the senses. Perhaps in the more artistic pursuits one would have an advantage if they could see things differently with an altered perception, but chess is objective and requires utmost mental clarity.

We all need aspirations to get by, and having a strong, talented heroine competing in a game dominated by men is a wonderful story if told right. Yet believability is subjective. Knowing the "vibe" of the kind of people that win national championships in intellectual games give off, prevents me from enjoy the story as most other people would. There's just not enough passion, not enough drive for self-improvement, not enough emphasis on self-discipline, and too much pettiness, too much plebbery. At a world championship level, every player is blessed with all the talent that is humanly possible -- it is a statistical impossibility that anybody, regardless of gender or race, could rely on mostly talent and barge in and win while being distracted by serious personal issues on the side. You compete by giving up less important things in your life to focus on doing what it takes make it to the very top. And the sad truth is that, the privileged requires fewer sacrifices. Hollywood made a valiant attempt at balancing our protagonist's passion, character and talent with her emotional struggles to make things relatable with the average viewer, but in retrospect given the ecosystem there, there's probably no way it could have succeeded in writing anything remotely believable (to me at least).

Cinderella is a more believable story if it had a fairy than if it had not. But the audience wanted a fairytale without a fairy-godmother nor a prince charming. The modern woman is too independent for that, they say. And so, after experimenting with drugs, alcohol and sex, the girl in dirty rags suddenly became Queen on her own, without even really half-struggling, just because.

The funny thing is, while women and men do of course pull off some incredible feats in real life by winning some sort of lottery (often genetic), the rules of fiction is different. Truth is stranger than fiction, they say, and I think they're right. You need a fairy in a fairytale. A story of some person winning some kind of lottery, then living happily ever after, makes for a horrible story because it's "unrealistic", even though this happens to many people on a daily basis.

Non-Dieting

早前老婆約咗十月尾補影婚紗相,九月同十月刻意減咗幾磅,大概由 Xkg 變成 (X-5)kg。主要都係食少啲飯(low-er-carb)同食少餐飯 (論量詞嘅重要性)。話說 Keto-Potato-Chips Diet 原來都減到幾磅,真係幾得意。

不過而家體重仍然係太高,繼續現時飲食習慣,似乎唔會再減到半磅 (有回升趨勢)。

所以趁住呢幾日冇咩約又唔使返工就開始嘗試重拾斷食嘅惡趣味。暫時發現,買餸同煮飯好難避免攝取能量,好難進入標準嘅 water fast 😞  尋日冇咩點食嘢,不過都食咗幾啖,今朝如所料淨係瞓咗六個鐘,幾精神。

下晝去咗買餸買食糧,返嚟忍唔住試咗幾啖,點知整個人進入咗 "食咗嘢" mode,頭暈腦脹。

不過都有啲幾有趣嘅實驗結果:食牛油(yes, eat)果然係唔會令身體有咩反應,反而食肉同麵豉湯就會有幾大反應。而家有少少眼瞓,真係唔知點搞。頂。

附上一包 Keto 雞皮圖片,早排喺 Donki 買嘅。

蝦膏

 原來蝦膏 (好似磚頭嗰種,唔係蝦頭入面嗰種) 可以加落熱油開稀用嚟做調味料,睇嚟幾好用。會得閒試下佢 (唔多鍾意用蝦醬)

Mox (virtual bank)

今日心血來潮開咗個 Mox 帳戶。

開戶流程非常順暢,果然係幾分鐘開到。個 user interface 亦都好好用,UX 一流。唯一令我有少少擔心嘅係⋯ 嘩連地址證明都唔使咁屈機?然後攞住我 HKID 同 電話就可以由其他銀行過數落嚟咁屈機?(如果咁做有問題,唔係 Mox 嘅問題而係香港行銀體制容許呢樣嘢嘅問題啩...) 感覺上佢哋一反傳統銀行常態,喺保安(*)同UX取得個平衡,真係幾唔錯。

* 所謂「保安」好多時只係令一件事更加難做保障銀行,係咪保障用家就反而有得斟酌...
