Vultr is a cloud computing company established back in 2014. Although they entered the industry for just less than 10 years, they really have dominated the “bang for the buck” market along with DigitalOcean and Linode. However, they recently (a few months ago) announced a Free Tier. Users need to debit their account 5$ via Credit Card and enable two-factor authentication. Although they claimed that only Credit Cards would work, actually any method will work, including Alipay, PayPal, Cryptocurrency, etc.
Proxmox Virtual Environment is a great virtualization platform. And Oracle Cloud Infrastructure seems to provide virtual machines for free forever. The regular x86_64 instance has only 1/8 OCPU and 1 GB RAM. However, the new Ampere instance is aarch64 (arm64) architecture. With 4 Neoverse N1 Cores and 24 GB RAM, we can fire up some decent containers on it. However, Proxmox doesn’t officially provide the tutorial (or even workarounds) to install Proxmox VE on an ARM computer.
In the modern era, cryptography has become one of the most important part of our digital life. We all know, cryptography is used to encrypt, sign, authenticate. Above all, the most important is of course, the security. We would never want anyone except ourselves (or the recipients, if applicable). So here are some advices based on my own experience. 1. Use proper algorithm. It depends on your needs. For example, would you like to use symmetric or asymmetric?
KURUN Cloud is a VPS company established back in 2019. They are an LIR of ARIN. From the website, I would guess that a group of Chinese people launches it, but headquartered in California, US. They have a great deal, you get 1 vCPU core, 1 GB RAM, 10 GB Disk for just 3$/month, and very good networking to China (it’s very obvious that this machine is the best choice for proxy.

A S/MIME (Secure/Multipurpose Internet Mail Extensions) certificate is a type of digital certificate that is used to encrypt and sign email messages. It allows the recipient of the email to verify the identity of the sender, and to ensure that the message has not been tampered with during transit. There are multiple companies that offer S/MIME certificates, such as DigiCert, GlobalSign, Comodo, and GoDaddy. You can also find other providers by searching online.

2022 Final Review

2022 Final Review This is December 31, 2022, 23:06 PM CST now. 2022 is a pretty terrible year for us, but there were still some noticable events which are worth noting. January: Nothing serious, took final exam of 8A, I remembered that it wasn’t too good. February: Get Chinese New Year, bought Google Workspace for the first time (and then got rid of it). Played Minecraft A LOT, but didn’t actually do anything meaningful.
Yubico is famous for its excellent hardware keys, and somehow they have become the industry standard. But unfortunately, for unknown reasons*, they don’t offer services to China (mainland), not even sell to China. That sucks since I live in China. (oof, don’t worry, but that’s how the story starts) How did I make up my mind to buy a YubiKey? It’s a long story, but long story short. I have been interested in cryptography for a few months, especially when it comes to things like OpenPGP, and I got to know a thing called Smart Card, which is a card that stores your private key.
Kimsufi is an affiliated company with one of the biggest providers in France – OVH. A couple of months ago, all of Kimsufi’s services are migrated to OVH and everything is now OVH’s. For 4.99€ (before tax, more on that later), you will get the following spec. Intel ATOM N2800 @ 1.86 GHz - 2 Cores / 4 Threads; 4 GB DDR3 1066 MHz; 1 x 1 TB SATA HDD*; Symmetric & Dedicated 100 Mbps Internet Connection.
Friendhosting is a VDS provider established back on April 20, 2009. So pretty old merchant. They offer Web Hosting, SSD VDS and HDD VDS for storage. The location for HDD VPS is only Bulgaria and Netherlands. Since they are all DMCA-ignored, it will be nice for torrenting. (Ignoring the disk speed, more on that later.) The base model is 2 vCPU, 512 MB RAM, and 100 GB HDD. I bought one, in Sofia, Bulgaria.
