這幾年對於開放式空間有不少反面意見出來,像是這幾天 BBC 登的「Why open offices are bad for us」。 這是目前的主流,大量的公司採用開放式空間: Numerous companies have embraced the open office — about 70% of US offices are open concept — and by most accounts, very few have moved back into traditional spaces with … Continue reading

歐盟法院 (The Court of Justice of the European Union) 認為公開無線網路的營運者不需要對使用者的侵權行為負責:「EU Court: Open WiFi Operator Not Liable For Pirate Users」。 不過這是有一些前提的,法院認為應該要符合這幾個要件,營運方才不要負責。基本上完全沒有 filter 限制的無線網路會符合這些條件: The Court further notes that in order for such ‘mere conduit’ services to be exempt from third party … Continue reading

Mark Callaghan 講最近的 MySQL 的行銷活動...

Mark Callaghan 這篇倒是沒提到什麼技術的東西,主要是講最近 MySQL 的兩大 conference,一個是 Oracle 的 Oracle Open World,另外一個是 Percona 的 Percona Live Amsterdam 2016,然後用了 benchmarketing 這個酸酸的詞 XDDD:「Peak benchmarketing season for MySQL」。 裡面有些也很有趣的東西: My joke is that each of these makes a different group happy: performance -> marketing, … Continue reading

Netflix 的 Open Connect 架構

在「研究人员绘制Netflix CDN服务器位置图」這邊看到在討論 Netflix 的 Open Connect 架構,也就是 Netflix 自己的 CDN 架構。引用的論文是「Open Connect Everywhere: A Glimpse at the Internet Ecosystem through the Lens of the Netflix CDN」這篇。 翻了一下論文,看起來還是頗傳統的方法,從一堆伺服器去 query 找出來: Indeed, Netflix server domain names are too specific, i.e., including details … 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

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
