Dropbox 也要搞自己的密碼管理器

Dropbox 也要搞自己的密碼管理器 Dropbox Passwords:「Dropbox Passwords coming soon for all users」。

看起來只要是 Dropbox 的付費方案就可以無限使用,而免費版的則是 50 組。從下載頁看起來目前在 PC 上只支援 Microsoft WindowsmacOS,不支援 Linux

Come back to this page on a PC with Windows 10 or a Mac with at least macOS Sierra 10.12 to get the Passwords desktop app.

而行動平台就是 iOSAndroid

How do I use the Android and iPhone password manager?

Once you sign in to the Passwords app, it automatically fills in your usernames and passwords so you can access frequently used apps and websites on your mobile device.

從示意圖看起來有整合瀏覽器,而加密技術的部份沒有講太多,只說是 zero-knowledge encryption,先觀望看看...

Figma 限縮免費帳號的功能

Plurk 上的這篇看到的,Figma 的 Free Starter Plan 縮減功能:「Starter plan updates」。

這步算是要使用者掏錢出來,進入養套殺裡「殺」的階段了。不過每個編輯者 USD$15/month 以價錢來說還好 (年繳的話還有一些折扣),團隊大多數的 viewer 是不額外收費的。

LastPass 開始進入「殺」的階段,免費使用者只能在一個平台上使用

LastPass 進入了「套養殺」最後一個階段「殺」,宣佈縮減 LastPass Free 的可用範圍。在 2021/03/16 開始 (一個月後),LastPass Free 的使用者只能選擇一個平台使用,像是「桌機平台」,或是「行動平台」:「LastPass’ free tier will become a lot less useful next month」,官方的新聞稿則是在「Changes to LastPass Free」這邊。

官方有提供第一年的限時優惠 (換算起來應該是一年 USD$27),但不給既有用戶,現有的用戶如果要的話得自己換帳號 export & import,不然就是用原價殺 (一年 USD$36):

If you’d like unlimited device type access and email support, you can upgrade from Free to LastPass Premium for a limited time, for $2.25 per month (billed annually). *

*Additional Terms and Conditions: Advertised price valid for new users on their first year of LastPass Premium. Price not valid for renewals or existing customers and cannot be used for other LastPass plans, products or services.


話說回來,這種東西我自己還是偏好用 open source 方案,然後自己搭同步機制,不過目前看到的方案在跨桌機平台與行動平台的確是痛點... 有需求的人應該還是會選 LastPass 或是 1Password 這樣的方案。

Zoom 最後決定所有使用者都有 End-to-end encryption 了

先前在「Zoom 不提供 End-to-end Encryption 給免費版用戶」這邊提到的事情,剛剛看到 Zoom 宣佈改變策略,變成無論是付費還是免費的使用者都會提供 End-to-end encryption:「End-to-End Encryption Update」。

Free/Basic 的使用者要認證才能用這個功能:

To make this possible, Free/Basic users seeking access to E2EE will participate in a one-time process that will prompt the user for additional pieces of information, such as verifying a phone number via a text message.


Lambda 被放進 Savings Plans 了

前幾天才在 Ptt 上回了一些對 Lambda 與 Serverless 的想法,結果剛剛看到 Lambda 被納入 Savings Plans 裡面了:「Savings Plan Update: Save Up to 17% On Your Lambda Workloads」。

最多 17% 的折扣,看起來比其他的低不少,應該是因為 Lambda 比起 EC2 或是 Fargate 更動態的關係:

Today I am happy to be able to tell you that Compute Savings Plans now apply to the compute time consumed by your AWS Lambda functions, with savings of up to 17%.

現有的 Savings Plans 如果沒有用完的部份也會自動套用進去。先放著看看...

AWS Outposts 總算要開始出貨了

去年 AWSre:Invent 喊的 AWS Outposts 總算是有東西要出貨了:「AWS Outposts Now Available – Order Yours Today!」。

放在自家實體的機櫃,然後掛到 AWS 上變成一個特殊的 region。目前一個特殊的 region 只能放 16 個機櫃,但預期之後可以更多:

Capacity Expansion – Today, you can group up to 16 racks into a single capacity pool. Over time we expect to allow you to group thousands of racks together in this manner.

不過要注意的是,需要有 AWS Enterprise Support 才能下單,而且看起來硬體的維修也包在內了:

Support – You must subscribe to AWS Enterprise Support in order to purchase an Outpost. We will remotely monitor your Outpost, and keep it happy & healthy over time. We’ll look for failing components and arrange to replace them without disturbing your operations.

看了一下價錢的頁面,如果以北美的 upfront 來算,最便宜的是 OR-L8IF4WFOR-I0OGL02 的 USD$225,504.81,最貴的是 OR-HSZHMMF 的 USD$898,129.52,暫時應該用不到 XDDD

Elsevier 限制加州大學的存取權限

三月的時候加州大學系統 (UC) 因為 Elsevier 不接受 open access 的條件而公開宣佈不續約 (參考「加州大學宣佈不與 Elsevier 續約」),後來 Elsevier 應該是試著看看有沒有機會繼續合作,所以在這段期間還是一直提供服務給加州大學系統。

前幾天在 Hacker News 上看到「Elsevier cuts off UC’s access to its academic journals (latimes.com)」,總算是確定要動手了:「In act of brinkmanship, a big publisher cuts off UC’s access to its academic journals」。

不過也不是直接拔掉,而是限制存取權,看不到新東西 (以 2019/01/01 為界):

As of Wednesday, Elsevier cut off access by UC faculty, staff and students to articles published since Jan. 1 in 2,500 Elsevier journals, including respected medical publications such as Cell and the Lancet and a host of engineering and scientific journals. Access to most material published in 2018 and earlier remains in force.

UC 提出的商業模式是讓投稿者負擔費用,而存取者不需要負擔,與現有的商業模式剛好相反。UC 提出的模式鼓勵「知識的散佈」,而現有的商業模式則是反過來,希望透過知識的散佈而賺~大~錢~發~大~財~:

UC demanded that the new contract reflect the principle of open access — that work produced on its campuses be available to all outside readers, for free.

That was a direct challenge to the business model of Elsevier and other big academic publishers. Traditionally, the publishers accept papers for publication for free but charge steep subscription fees. UC is determined to operate under an alternative model, in which researchers pay to have their papers published but not for subscriptions.

另外在 Hacker News 上的 comment 裡看到一些專案也正在進行,像是歐洲的「Plan S」也是在推動 open access:

The plan requires scientists and researchers who benefit from state-funded research organisations and institutions to publish their work in open repositories or in journals that are available to all by 2021.

另外「PubPub · Community Publishing」也是 open source 領域裡蠻有趣的計畫,後面看起來也有不少學術單位在支持。

Cloudflare 推出 Spectrum:65535 個 TCP Port 都可以轉的 Proxy...

Cloudflare 推出了 Spectrum,文章標題提到的 65533 應該是指 80 & 443 以外其他的 port:「Introducing Spectrum: Extending Cloudflare To 65,533 More Ports」。

然後因為 TCP proxy 不像 HTTP proxy 與 WebSocket proxy 可以靠 Host header 資訊判斷,在 TCP proxy 需要獨占 IP address 使用 (i.e. 一個 IP address 只能給一個客戶用),而因為 IPv4 address 不夠的關係,這個功能只開放給 Enterprise 客戶用:

Today we are introducing Spectrum, which brings Cloudflare’s security and acceleration to the whole spectrum of TCP ports and protocols for our Enterprise customers.

雖然現在限定在 Enterprise 客戶,但 Cloudflare 還是希望看看有沒有其他想法,目前提出來的選項包括了開放 IPv6 address 給所有人用,或是變成獨立付費項目:

Why just Enterprise? While HTTP can use the Host header to identify services, TCP relies on each service having a unique IP address in order to identify it. Since IPv4 addresses are endangered, it’s quite expensive for us to delegate an IP per application and we needed to limit use. We’re actively thinking about ways to bring Spectrum to everyone. One idea is to offer IPv6-only Spectrum to non-Enterprise customers. Another idea is let anyone use Spectrum but pay for the IPv4 address. We’re not sure yet, but if you prefer one to the other, feel free to comment and let us know.

類似的產品應該是 clean pipe 類的服務,但一般 clean pipe 是透過 routing 重導清洗流量,而非像 Cloudflare 這樣設計... 不知道後續會有什麼樣的變化。

2011 年的研究,開放辦公室與病假的關聯性

忘記從哪邊冒出來的連結,反正是個 2011 年的研究:「Sickness absence associated with shared and open-plan offices--a national cross sectional questionnaire survey.」。2011 年在丹麥的研究:

METHODS: The analysis was based on a national survey of Danish inhabitants between 18-59 years of age (response rate 62%), and the study population consisted of the 2403 employees that reported working in offices. The different types of offices were characterized according to self-reported number of occupants in the space. The log-linear Poisson model was used to model the number of self-reported sickness absence days depending on the type of office; the analysis was adjusted for age, gender, socioeconomic status, body mass index, alcohol consumption, smoking habits, and physical activity during leisure time.

都是與 cellular office 比較,可以看出大於六個人的開放辦公室病假的量高出許多:

RESULTS: Sickness absence was significantly related to having a greater number of occupants in the office (P<0.001) when adjusting for confounders. Compared to cellular offices, occupants in 2-person offices had 50% more days of sickness absence [rate ratio (RR) 1.50, 95% confidence interval (95% CI) 1.13-1.98], occupants in 3-6-person offices had 36% more days of sickness absence (RR 1.36, 95% CI 1.08-1.73), and occupants in open-plan offices (>6 persons) had 62% more days of sickness absence (RR 1.62, 95% CI 1.30-2.02).

CONCLUSION: Occupants sharing an office and occupants in open-plan offices (>6 occupants) had significantly more days of sickness absence than occupants in cellular offices.

看起來只是拉數字出來分析... 另外信心區間的洞好大 XD

VaultPress 的新方案

VaultPressWordPress 的付費服務,可以備份自己架設的 WordPress 站台。

剛剛看到新的方案出爐了:「Announcing Streamlined Plans — at Lower Prices」,Jetpack Personal 將本來的 VaultPress Lite 包在內,但是價錢更低了:

At $3.50 per month, the Jetpack Personal plan includes everything the old VaultPress Lite plan used to — at a price that’s 30% lower.

有在用的人記得進去更改方案,另外要注意生效時間,等原來 Lite 快到期再改。
