AWS 宣佈 EBS io2 的新花樣 Block Express Volumes

看到「AWS Announces General Availability of Amazon EBS io2 Block Express Volumes」這篇,在 EBSio2 上面又推出了新的花樣 Block Express Volumes:

Today AWS announced general availability of io2 Block Express volumes that deliver up to 4x higher throughput, IOPS, and capacity than io2 volumes, and are designed to deliver sub-millisecond latency and 99.999% durability.

要再提供更高的效能,在 R5b 的機種下,單個 volume 可以拉到 256k IOPS 與 4000MB/sec 的傳輸速度,以及在 well-tuned 的環境下 (應該是多個 volume) 可以拉到 260k IOPS (多一點點) 與 7500MB/sec (將近原來的兩倍) 的傳輸速度:

Using R5b instances customers can now provision a single io2 volume with up to 256,000 IOPS, 4000 MB/s of throughput, and storage capacity of 64 TiB.

R5b instances are well-suited to run business-critical and storage-intensive applications as they offer the highest EBS-optimized performance of up to 260,000 IOPS and 7,500 MB/s throughput.


筑波快線因為提早 20 秒開車而道歉

居然是從 Hacker News Daily 上看到的:「Apology after Japanese train departs 20 seconds early」,引用的是官方的道歉文:「【お詫び】南流山駅における普通列車の早発について」。



更有趣的是 Hacker News 上的討論 (在這裡),一如既往的無法理解日本的鐵路與電車為什麼可以這麼準時 XDDD

日本電車要大幅延遲,最常見的就是人身事故以及暴雪暴雨之類的吧,營運方的問題不是很常看到... (不過這個案例是提前開車而道歉,純粹看討論時想到而已...)

Google 在舊金山與洛杉磯開始宅配生鮮食品...

Google Express 延伸業務到生鮮食品上:「Google Launches Fresh-Grocery Deliveries」,與生鮮業者合作。

Google said it would begin delivering produce, meat, eggs and other perishable goods on Wednesday in parts of San Francisco and Los Angeles. The service is part of Google Express, which partners with retailers in some U.S. cities to deliver goods to consumers within hours of an order.


Alphabet Inc.'s Google is expanding its same-day delivery service to fresh groceries, the latest example of the tech titan’s increasing push into consumers’ daily lives.

我以為會掛在 Alphabet 下做,而不是在 Google 下做...

把 Raspberry Pi 當作 AirPlay 裝置放音樂...

Raspberry Pi 模擬成為 AirPlay 裝置,再外接喇叭:「Hacking a Raspberry Pi into a wireless airplay speaker」。

用到 ShairPort (模擬 AirPort Express 的軟體),而 ShairPort 目前只支援聲音的部份,所以現在只能接喇叭... 有人實做影像的時候應該就會有人把 HDMI 接上去了 :p
