Libreboot 成功的讓 FreeBSD/OpenBSD 開機

Libreboot 是一個 open source 版本的 BIOS/UEFI 替代品:

Libreboot is a free BIOS or UEFI replacement (free as in freedom); libre boot firmware that initializes the hardware and starts a bootloader for your operating system.

而最近的版本則是順利的在沒有修改作業系統來配合 Libreboot 的情況下將 FreeBSDOpenBSD (不過是 kOpenBSD) 開起來了:「Re: [Libreboot] GNU Libreboot, version 20160818 released」。

Love your country, but never trust its government

Hacker News Daily 上看到的,在 Sun-2 的 bootloader 裡可以看到「Love your country, but never trust its government」這樣的字串:「Why the Sun 2 has the message "Love your country, but never trust its government"」。

這段字串是由 John Gilmore 當時在 Sun 開發時所放入的,John Gilmore 同時也是後來 EFF 創辦人之一,不過當初放入這段字串的目的是為了抓到盜版:

Yes. Vinod Khosla, first President of Sun, came to me at one point and said to put something hidden, triggered in an unexpected way, into the ROM Monitor, so that if somebody cloned the Sun Workstation (violating our software’s copyright), we could do that unexpected thing to the competitor’s demo workstation at a trade show and thereby prove that they had cloned it.

過了三十年後 John Gilmore 被挖出來問的回應也是蠻有趣的... (可以參考原文附上的信件)

而這句話現在回頭看也很經典,尤其是最近各國政府想要在 crypto system 裡面放後門的各種反應。

溫水煮青蛙:Windows 10 與 Secure Boot

Microsoft 的 Windows 10 更進一步限制了 Secure Boot 的選擇:「Linux’s worst-case scenario: Windows 10 makes Secure Boot mandatory, locks out other operating systems」。

之前是關閉,現在則是必須要 optional (包裝用語啦,意思是預設值打開,使用者可以進 UEFI console 關閉):

OEMs are still required to ship Secure Boot, but the previously mandatory disable switch is now optional

是個「溫水煮青蛙」的概念,如果這次沒擋下來,下一次 Microsoft 就會規定 OEM 出版只能在安裝在強制打開 Secure Boot 的機器上使用 (不能關閉)。

Go 的 self-boot 計畫

Go 的 self-boot 計畫,也就是用 Go compiler 編 Go compiler:「Russ Cox – porting the Go compiler from C to Go」。

其中提到:

The goal is to convert *their* C code (not all C code). They want generated code to be human-readable and maintainable. They want automatic conversion to handle 99+% of code.

第一波想要用機器轉換過去,而且要轉出可維護的程式碼。可以馬上想到的事情是,如果這件事情成功,代表現有軟體的 C code 也有機會轉移?

接下來了幾個版本會開始發展整套機制,有得瞧了 :p
