Monero dynamic block weight is an interesting design. Instead of a fixed supply of transaction space, Monero uses the history blocks to determine the dynamic limit and use the median to control the increasing pace.

In bitcoin, the total size of transactions added to the chain in a specific time is limited. This creates a fee market. Transactions with a higher fee rate are likely to be confirmed more quickly. A good fee estimator predicates which fee rate to pay where there is a high probability the transaction will be confirmed into the chain within the target period. Bitcoin core has the builtin support to estimate the fee rate. Understanding its algorithm can help us to migrate it and improve it. This first part of this article introduces the core estimation algorithm. The algorithm determines which statistics data to track, and the second part shows how Bitcoin Core tracks them. The last part describes the extensions to the core algorithm for better performance.

This post records how I set up Yubico Key in Windows, so I’ll not delve into too much details. I have the model YubiKey 5 NFC. I frequently use 2 GPG keys stored in the key, one for encryption, another for SSH authentication. The GPG encryption part is simple, GnuPG just works. Using the stored GPG key for SSH is a bit complex, because it requires collaboration between GnuPG and the SSH client. After experiment many different solutions, I decide to use the simplest one, using putty/plink as the SSH client and enabling thepageant support in GnuPG. See ♯ SSH Authentication Using a YubiKey on Windows And the OpenSSH Client how to use OpenSSH client with YubiKey.

The article mainly refers Exercise 2 - Track User Mode Process Allocations | Microsoft Docs. 1. Install Windows Performance Recorder and Analyzer Download and install ADK from here. The windows build version can be checked by running “winver” via Win+r.

Following example moves the Ubuntu distribution to disk D:\WSL\Ubuntu.

I prefer using a dedicated WSL instance to run containers. So I’ll install a minimal distribution, Alpine, to run podman. Install the tool LxRunOffline first via scoop scoop bucket add extras scoop install lxrunoffline Download Alpine root package from https://lxrunoffline.apphb.com/download/Alpine. See more distributions in LxRunOffline Wiki.

There are two apps both work for me in scoop extras bucket. scoop bucket add extras scoop install rbtray traymond They both require running their background process first. Rbtray minimizes a window into system tray by right clicking the window minimization button, while traymond us shortcuts Win + Shift + Z。

I used to use Visual Studio Code in Windows as mentioned in a previous post, ♯ My Windows Environment Setup. But its startup time is terrible on Surface Go, so I decide to give vim another try.

A friend recommended gopass to manage passwords. After the trial, I decided to switch.

I have only one Windows device, the Surface Go. I work on it occasionally, especially on short trips. I prefer Surface Go because of handwriting. I have a simple setup to meet my work requirements.
