Open Source 版本的 Skype

前幾天講到用 Docker 跑 Skype 的「用 Docker 跑 Skype 講電話」,剛剛就看到「skypeopensource2」這個專案,不過目前功能非常有限: First in world self-made client to Skype Network based on reversing original Skype 5.5 client. For now, only receiving and sending messages are supported. 然後看了一下專案內容,應該是 Windows-only,這樣應該還是暫時會用 Docker 版本的 Skype 吧... 最主要還是拿來打電話 … Continue reading

在遊戲上模擬跑步的動作

從「Balls to learning how to animate, let's film some parkour!」這篇看到讓人懷念的遊戲,1989 年的《波斯王子》: Jordan Mechner (波斯王子的作者) 用 Rotoscoping 的方式將他弟弟做這些動作的畫面拍下來,然後確保在電腦上角色的動作是順暢的: Here's the source frames used to rotoscope the above animation.

另外一篇講文件掃描的...

在「Page dewarping」這篇看到講文件掃描的技術,以及 open source 的程式,對比之前提到的「Dropbox 的文件掃描功能」與「Dropbox 的 Document Detecting」的時間點,有種淡淡的惡意 XD 這篇作者是為了未婚妻的需求而寫出來的,本來是作者收到學生的作業時手動在跑,後來未婚妻也拿去用,但量愈來愈大,決定自動化處理: A while back, I wrote a script to create PDFs from photos of hand-written text. It was nothing special – just adaptive thresholding and combining multiple images into a … Continue reading

Linksys 的 WRT54GL

前幾天跟同事聊到 Android 刷機的事情,而最近剛好看到介紹這台無線分享器裡的名機,Linksys 的 WRT54GL:「 The WRT54GL: A 54Mbps router from 2005 still makes millions for Linksys」,第一款被廣泛應用在各種客製化硬體的機器。 取自維基百科的「File:Linksys WRT54G.jpg」 從 2005 年開始賣,到現在 2016 年還是繼續在賣,而且這東西支援的無線規格很舊,還比其他的無線分享器貴不少: Witness the Linksys WRT54GL, the famous wireless router that came out in 2005 and is still … Continue reading

Google 在 AOSP 裡加入對 Raspberry Pi 3 的支援:「Google to bring official Android support to the Raspberry Pi 3」,repository 可以在「device/pifoundation/rpi3/」這邊看到,目前是空的,不過這讓大家就有很多想像了: For now, the Pi 3 device tree is empty with only the comment "initial empty repository" accompanying it. The repository should … Continue reading

解譯機械碼的 Panopticon

Panopticon 看起來頗不錯,可以直接解機械碼轉成 assembly,再把 flow 畫出來讓人理解: 不過還不知道遇到 dynamic self-decoding 的程式會怎麼處理,另外我記得好像有些商用的 solution 已經有提供了,不知道相比起來如何。
