這篇文章在說使用Mac電腦 Apple似乎有做多餘監控行為.
https://github.com/…/macOS-Securit…/blob/master/README-cn.md
因此用盡各種方法想保障自己隱私.

其實監控跟保護 是一體二面
OSSLab在20年前 就嘗試過改寫一顆spi eeprom 破解IBM 筆電加密晶片 ,在此架構下硬碟會被ATA加密,但在硬碟韌體hacker前 是不堪一擊的(ssd 跟新款HDD例外)
但是Apple 上了bios密碼 與apple id 保護沒有這樣簡單....
Bios (efi) 密碼逆向請參考
https://www.osslab.com.tw/reverse-mac-efi-scbo/
光解決掉efi password不夠,另外還有apple id 中的find my computer
https://www.osslab.com.tw/mac-protect-security/
就算你電腦efi密碼被清除,系統被重灌
不管有沒有連網路(免密碼的wifi照連),mac os 開啟啟動會將序號傳回apple
一但發現此序號被綁定就會lock電腦或erase data ....
隱私與防護必須取得一個平衡點

【迷思】脂肪的體積是肌肉的N倍？

「脂肪的體積是肌肉的三倍」、「四倍」、

甚至「五倍」、「十倍！！」Σ(;ﾟдﾟ)

或許你曾聽過哪個健身部落客、健身教練、

商業健身房這樣說過。
　

但是，實情並非這樣：

事實上，相同重量下，

脂肪的體積只比肌肉多了0.15~0.20倍。

(聽起來好弱 ｡•ㅅ•｡)
　

類似的迷思還有：

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
(X) 1kg 的脂肪每天只能消耗3~5大卡，而肌肉卻能消耗60~100大卡

(O) 1kg 脂肪一天消耗4~9大卡， 肌肉則是13~22大卡，兩者並沒有天差地遠
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
(X) 4分鐘HIIT效果可以抵有氧運動30分鐘

(O) 4分鐘HIIT效果可以抵有氧運動7分鐘
- - - - - - - - - - - - - - - - - - - -- - - - - - - - - - -

　
雖然以上的破解最終不會改變

「我們注重的是體態，而非數字」這個結論，

但是我們應該要認清事實

「重量訓練可以改變體態，但並非神效，也並非神速。」

真的有在認真重訓的人應該不難理解，

我們往往努力了一年半載，

身旁的親朋好友才意識到我們的改變。

但慶幸的是，儘管要走的路很長，但只要持續努力，

改變就會慢慢的累積，

累積到自己更愛自己的地步，累積到旁人也開始不禁羨慕。

Please share this so we can clear up this misconception‼️

I'm sure you've seen the images floating around the Internet showing what 5lbs of fat vs. 5lbs of muscle looks like. The replicas typically shown are a giant blob of fat next to a tiny mound of muscle, and you're inevitably left believing that 5lbs of fat takes up 5x more space than 5lbs of muscle.

This is a myth! 🚫In actuality, the density of mammalian skeletal muscle tissue is 1.06kg/L, while that of adipose tissue is 0.9196kg/L. In other words, fat only takes up 15% more space than muscle.

So 5lbs of fat weighs the same as 5lbs of muscle - obviously! But muscle is only slighter more dense than fat.

How did this misconception arise? I do not know, but I surmise that some sleazy marketer fabricated the idea to sell a product or service by dramatizing the visual effects of getting into shape. 🤷🏽‍♂️Whatever the case, this individual clearly never chased down the science like I did. Unfortunately, these images are so common nowadays that they aren't questioned and are passed along as fact. Exaggeration is never a good idea; people deserve the truth! 🙌🏽
