Framework 筆電也遇到缺料問題，換了音源晶片
Framework 的筆電最近在社群很紅，模組化設計讓維修變容易，而且也有許多規格上的客製化空間。在「Marketplace」這頁可以看到很多東西可以換，除了比較常見的無線網卡、SSD、記憶體以外，像是主機板、鍵盤甚至連 USB、HDMI 接口都是模組。
不過這邊要提到的是 audio chip 也在這波 supply chain 的供貨問題而中招了：「Solving for Silicon Shortages」，Hacker News 上的討論「Framework: Solving for Silicon Shortages (frame.work)」也可以看一下。
從文章裡看起來是 Realtek ALC295 的交期爆炸了：
Chips that would normally have 16-20 week lead times (meaning we’d place typically binding orders that far ahead of needing parts in our hands) went up to 52 weeks. In one case, we even got notified of a 68 week lead time on a chip!
We were able to get enough Realtek ALC295 audio CODECs to develop the Framework Laptop and get through the first few months of production, but nowhere near enough to fulfill ongoing demand from the US and Canada, let alone the additional countries we’d like to ship to.
所以決定換到 Tempo 92HD95B：
Luckily, we were able to find an alternative CODEC that lets us stay in production: the Tempo 92HD95B.
查了一下 datasheet，本來的 Realtek ALC295 是 QFN-48，而 Tempo 92HD95B 是 QFN-40，看起來得改不少東西... 應該是連 open market 上都翻不到而被迫換設計，跟我們家的情況也很像，看起來最近大家都哭到爆炸了 :o

在 ThinkPad T530 上跑 FreeBSD 的介紹
作者在「FreeBSD on a Laptop」這邊寫下了在 ThinkPad T530 上跑 FreeBSD 的完整攻略。 查了一下 ThinkPad T530，這應該是 2012 年就推出的筆電了 (五年多前)，所以文章的重點在於要去那邊找解法 (i.e. 方向性)。另外作者有提到文章是假設你已經對 FreeBSD 生態算熟悉 (像是 Ports 以及 /etc 下設定檔習慣的格式與設定方式)： Unlike my usual posts, this time I'm going to assume you're already pretty familiar with FreeBSD. 然後有點無奈的地方... 即使是 2012 年的電腦，為了 driver 問題他還是得跑 -CURRENT： In my case,…

筆記型電腦的充電器單一化...
在 Slashdot 上看到「Standardized Laptop Charger Approved By IEC」這篇。 2011 年年初的「歐盟強制使用 Micro USB 做為手機充電介面」後，IEC 這次宣佈要標準化筆電的充電器：「Major milestone: single charger for notebook computers will significantly reduce e-waste」。 目前的進度在最後一段可以看到： IEC Technical Specification 62700: DC Power supply for notebook computer, will be available in early 2014. 不過... 筆電充電器這塊如果要做的好用，不會卡到蘋果的專利嗎？

iPhone 的電池與效能
在 Hacker News 上看到 Reddit 上的這則說明：「PSA: iPhone slow? Try replacing your battery!」。 他提到他的 iPhone 6S 很慢，本來以為是 iOS 11 導致的，結果發現他弟弟 (或是哥哥？) 的 iPhone 6 也是跑 iOS 11，但是快很多... 所以他就試著研究，最後決定換電池： My iPhone 6S has been very slow these past few weeks, and even after updating multiple times, it was still slow. Couldn’t figure…
