Android 上透過 DAC (i.e. 耳機或是喇叭) 再做 ADC (i.e. 麥克風) 的傳輸

看到「Quiet for Android - TCP over sound」這個給 Android 用的專案,就是以前的撥接數據機嘛... 在直接拉線對連時連速度都還蠻像的: Quiet's provided audible mode transfers at approximately 7kbps. In cases where two devices are connected over a cable (via 3.5mm jack) it can run in cable mode, which transfers at … Continue reading

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

用 Docker 跑 Skype 講電話

Update:中文的部份是有問題的。之前以為是跑 Docker 版本時,實際上跑到很久前裝的 skype... 移除後發現 voice 沒問題,但沒有中文字型... 因為 Skype 裡面不知道跑了什麼東西,所以想要用 Docker 包起來放在 container 裡面跑,但之前測起來不穩定,而且中文字型的問題一直沒解決,所以就先一直丟著。 而剛剛測了一下 sameersbn/docker-skype 這邊的版本,發現之前遇到沒辦法看中文的問題也解決了。 安裝的方法非常簡單,先拉下來,然後執行他: $ docker pull sameersbn/skype:latest $ docker run -it --rm --volume /usr/local/bin:/target sameersbn/skype:latest install 這樣就會產生 /usr/local/bin/skype,直接跑他就好了,登入後再拿自家電話撥號,測了一下沒什麼問題。另外中文輸入法也是吃 host 的,所以也很順,弄得頗不錯的...

Amazon SNS 可以發簡訊到全世界了...

Amazon SNS 的新進展,簡訊可以發到全世界了 (之前應該是只能發到美國?):「New – Worldwide Delivery of Amazon SNS Messages via SMS」。 拉台灣的數字出來可以看到即使是最便宜的台灣大哥大 (Taiwan Mobile) 每通也要 NTD$1.35 左右,其他家就貴翻了... (所以應該是跟台哥大合作對接?) 不過對於本來就有用 AWS 服務的人來說,帳單是在同一張,報起來比較省事...
