Between Kagi and Orion, we are currently generating around $26,500 USD in monthly recurring revenue, which incidentally about exactly covers our current API and infrastructure costs.
如同 commit log 裡面提到的，這個功能會想要故意沒事就送一些沒用的資料 (增加一些噪音)，降低從 side channel 被判讀的資訊量：
This attempts to hide inter-keystroke timings by sending interactive traffic at fixed intervals (default: every 20ms) when there is only a small amount of data being sent. It also sends fake "chaff" keystrokes for a random interval after the last real keystroke. These are controlled by a new ssh_config ObscureKeystrokeTiming keyword/
基於 OpenSSH 算是 SSH 這塊的 de-factor standard 了，接下來看其他家像是 Dropbear 會不會也實作？
There already has been several very popular discussions around this (see here, here and the epic here). The gist of it is: what people really want is to have one global "Gitlab network" to be able to interact between various projects without having to register on each of their hosts.
Amazon SES 預設是共用 IP pool，所以遇到這種情況不算太意外，但應該是暫時性的，不過發問的作者有提到後來的解法是花 US$25/mo 使用 Dedicated IP 解決 IP reputation 的問題 (在 id=37177533 這邊)：
Thanks you all for comments. I have made a decision to subscribed to dedicated IPs (credits: @slau).
The differentiating factor between our current AWS SES plan and the competitors (mentioned in the comments) is having a dedicated IP. With our current volume, none of the competitors are anyway near AWS SES costs. So, moving to a dedicated IPs thats cost 25$ extra not only solves our issue, but also no change in code/infrastructure.
AWS Outposts is a family of fully managed solutions delivering AWS infrastructure and services to virtually any on-premises or edge location for a truly consistent hybrid experience. Outposts solutions allow you to extend and run native AWS services on premises, and is available in a variety of form factors, from 1U and 2U Outposts servers to 42U Outposts racks, and multiple rack deployments.
Build with AWS managed secure cloud infrastructure
Benefit from the same AWS security standards that apply to AWS Regions and AWS Local Zones and are delivered with the security of the AWS Nitro System to help ensure confidentiality and integrity of customer data.
另外在公告裡面提到的服務，跟 Outposts 有些差異：
AWS services, such as Amazon EC2, Amazon Virtual Private Cloud (Amazon VPC), Amazon Elastic Block Store (Amazon EBS), Elastic Load Balancing (ELB), Amazon Elastic Container Service (Amazon ECS), Amazon Elastic Kubernetes Service (Amazon EKS), and AWS Direct Connect are available in Dedicated Local Zones.
Q: How are AWS Dedicated Local Zones different from AWS Outposts?
AWS Outposts is designed for workloads that need to remain on-premises due to latency requirements, where customers want those workloads to run seamlessly with their other workloads in AWS. AWS Outposts racks are fully managed and configurable compute and storage racks built with AWS-designed hardware that allow customers to run compute and storage on-premises, while seamlessly connecting to AWS’s broad array of services in the cloud.
AWS Dedicated Local Zones are designed to eliminate the operational overhead of managing on-premises infrastructure at scale. Some customers have long-term, complex cloud migration projects and need infrastructure that seamlessly scales to support their large-scale demand. Some of these customers represent the interests of a customer community and also need multi-tenancy features to efficiently coordinate across their stakeholders. Dedicated Local Zones enable these customers to reduce the administrative burden of managing their own infrastructure on-premises with scalable, resilient, and multitenant cloud infrastructure that is fully AWS-managed and built exclusively for their use.
Storage Price: Effective October 3, 2023, we are increasing the monthly pay-as-you-go storage rate from $5/TB to $6/TB. The price of B2 Reserve will not change.
Computer Backup Pricing: Effective October 3, new purchases and renewals will be $9/month, $99/year, and $189 for two-year subscription plans, and Forever Version History pricing will be $0.006/GB/month.
This tool shows all commands and locks in postgres. If you select a command, it lists the locks that it acquires, commands that conflicts with it and commands that are allowed to run concurrently with it (with no conflict or blocking). If you select a lock, it lists commands that acquire the lock and what are the other conflicting locks.
Unlike ours, the manufacturer’s M1 drivers are unfortunately not conformant for any standard graphics API, whether Vulkan or OpenGL or OpenGL ES. That means that there is no guarantee that applications using the standards will work on your M1/M2 (if you’re not running Linux).
Tor's PoW defense is a dynamic and reactive mechanism, remaining dormant under normal use conditions to ensure a seamless user experience, but when an onion service is under stress, the mechanism will prompt incoming client connections to perform a number of successively more complex operations. The onion service will then prioritize these connections based on the effort level demonstrated by the client.
主要原因是傳統遇到 DoS 時可以透過 IP address 之類的資訊設計阻擋機制，但在 Onion 服務裡面沒有這個資訊，所以需要其他方式阻擋：
The inherent design of onion services, which prioritizes user privacy by obfuscating IP addresses, has made it vulnerable to DoS attacks and traditional IP-based rate limits have been imperfect protections in these scenarios. In need of alternative solutions, we devised a proof-of-work mechanism involving a client puzzle to thwart DoS attacks without compromising user privacy.
