鬆懈的下場:iPhone XR刮傷
Meow自2018年10月購入iPhone XR黑色款以來,長期都套當時一同購買的保護殼,長達兩年時間僅取出數次清潔,因此iPhone XR曾經一直保持近乎全新。 2020年底至今為防止遊戲造成iPhone XR過熱而卸下保護殼,僅出遠門才套上,然而缺少保護殼後在非出遠門的場合仍發生意外。數月前充電途中因同時在附近連接其他設備,不小心拉扯充電線導致iPhone XR滑落,好在充電位置離地板近,邊框僅留下非常不明顯的印記,自此十分注意充電環境。 後來發生的意外更加嚴重。2021年6月27日,這天是個星期天,Meow去附近買午餐,等待過程中途下起暴雨,回程意圖減少雨淋而小跑步,iPhone XR卻從口袋飛出。儘管螢幕毫髮無傷,背面玻璃下方有多道細微刮痕,鏡頭玻璃邊緣略有磨損,而邊框甚至因摩擦產生四道刮痕,肉眼清晰可見,白色鋁合金外露和黑框形成明顯反差。 屢次充分檢查,瞭解沒有任何地方裂開,手機功能一切正常,拍照成像沒有影響,算是這台iPhone XR命大,然而邊框刮痕掉漆還是需要解決。由於是黑色款,可用普通的方式試圖修補,因此傍晚購入雙頭奇異筆,先以1毫米筆頭基本填補,再以0.5毫米筆頭修飾細節,靜置一段時間後對較大刮痕再上一層。 修補結果當然不算完美,在明亮環境下特定角度會反光而察覺刮傷位置,但平時若非細看其實不容易發現,比起原本明顯的白色掉漆刮痕,填補後的邊框已不影響觀瞻,而且奇異筆屬油性,經測試觸摸和沾水都不會脫落,儘管未來時間久了也可能緩慢脫落,但使用奇異筆就能快速復原。 就算iPhone XR邊框外觀大致修復,傷害仍是永久,只要手摸即可感受不平滑的觸感,再加上還有前面提到的反光。Meow的iPhone XR至此不再完美,但這也深深警示了Meow,待人處世只要一鬆懈,就會有意外發生,需要承受的代價更是一生一世。自此Meow只要出門攜帶手機,必會戴保護殼,避免歷史重演。
DEPTHY另類用途
網上很多評測介紹過三維看圖工具DEPTHY,加上灰階景深圖即能呈現3D效果,原理是越亮越遠、越暗越近。DEPTHY還能建立GIF動畫,物件即可重複水平、垂直或繞圈移動。但Meow不打算介紹如何使用,而是它的另類用途。
Alternative usage of DEPTHY
Many reviews on the internet have introduced DEPTHY, a three-dimension viewer by applying a greyscale depth map— the brighter the farther, the darker the closer. You can use DEPTHY to create an animated GIF so the objects can repeatedly move horizontally, vertically or circularly. Meow is not going to show how to use it, but… Continue reading Alternative usage of DEPTHY
老Mac升級macOS 11.2提醒
根據Dortania教程,升級OpenCore到0.6.6之前應先在config.plist設定: 然後需到OpenCore選單重置NVRAM,按下空白鍵顯示,或在config.plist設HideAuxiliary為False。 再次進入macOS後,更新OpenCore至0.6.6並在config.plist設MaxBIOSVersion(老Mac專用)為True。強烈建議老Mac更新OpenCore至0.6.6以後才更新macOS到11.2。 另外現在OpenCore選單更真實了。
Reminder for legacy Macs updating to macOS 11.2
According to the Dortania guide, before updating OpenCore to 0.6.6, you should set these in config.plist: Then you have to reset NVRAM on your OpenCore menu. You have to press the Space key to show the option, or set HideAuxiliary to False in config.plist. After booting to macOS again, update OpenCore to 0.6.6 and set MaxBIOSVersion (exclusive for legacy Macs) to True in config.plist. I… Continue reading Reminder for legacy Macs updating to macOS 11.2
解決macOS色帶問題
macOS可能在外接顯示器呈現色帶,要解決需參照以下步驟: 這方法適用近年發行的macOS,含Big Sur(版本11),並不需要停用SIP或其他安全功能。

Colour banding of WebP & AVIF
WebP has been promoted as the next-generation image format (for ten years!), and then its powerful competitor AVIF comes. Do they work as excellent as people’s expectations? Unfortunately, colour banding happens on both of the new image formats.
