LinSNPGT: Genotyping specified SNP loci on Linux systems General introduction background Test Data Install SNPGT SNPGT-build contact us General introduction We have developed a toolkit WinSNPGT for calling variant sites on Windows systems, which is very friendly to those with little Linux operating experience. It obtains genotypes from raw sequencing data for a specified SNP […]

Cesium mouse clicks on the map to draw a point at the clicked location
Draw a point wherever the mouse clicks Directly copy the last picture code, any HTML with cesium, you can experience it directly as shown in the picture Let me explain it step by step. Finally, I will put the overall code at the bottom. Cesium is too difficult to learn. Compared with other languages, there […]
[Data processing] python Matplotlib partially enlarges the figure; marks the local enlarged subfigure of interest
Foreword In data visualization, it is often necessary to partially enlarge the data in a certain interval to obtain a higher contrast visualization effect. The following uses the Matplotlib library of the Python language to implement a simple partial magnification effect. Dependent libraries matplotlib: plotting library numpy: an extended library that supports a large number […]

ESP32/ESP8266 drives 1.8″tft_oled screen imitation digital tube clock based on Arduino framework
ESP32/ESP8266 drives 1.8″tft_oled screen imitation digital tube clock based on Arduino framework Related article “ESP32 drives I2C OLED time display based on U8g2 under Arduino framework” Effect demonstration: The screen display part uses the TFT_eSPI library driver and uses the unique font display that comes with the library. The screen adopts 128*160 1.8″tft_Oled screen. This […]
51 microcontroller + DS1302 design an electronic clock (LCD1602 displays time)
1. Preface An electronic clock is a device that can accurately display time. It is widely used in homes, offices and public places, providing people with convenient and accurate time information. This project designs an electronic clock based on 51 microcontroller, using DS1302 as the RTC clock chip, LCD1602 as the display screen, and connecting […]
Python multithreading: Unlocking the dance of program concurrency
In the world of computer programming, multithreading is a powerful and complex technology that provides programmers with a way to perform multiple tasks at the same time. Python, as a popular programming language, also provides multi-threading support. This article will deeply explore the concept and working principle of multi-threading in Python, and lead you into […]
How to understand and select optimistic locks and pessimistic locks during back-end development?
The author was asked this practical question when participating in a soft opening interview at a bank, so I came here to learn and summarize it. To get straight to the point, when choosing between pessimistic locks and optimistic locks, you need to consider the specific application scenarios: Pessimistic locking is suitable for scenarios where […]
Transactions and locking mechanisms in Redis
Transaction and lock mechanism in Redis Redis’s transaction mechanism is a mechanism that packages multiple commands for execution, ensuring that all of these commands either execute successfully or fail without any intermediate status. In Redis, transactions are implemented through four commands: MULTI, EXEC, DISCARD and WATCH. MULTI: This command marks the beginning of a transaction. […]
What are the problems with Redis distributed locking and how to solve them?
Suppose there is a scenario where you buy a ticket on a ticket purchasing software, but there are only one or a few tickets left. At this time, dozens of people are using this software to purchase tickets at the same time. Without considering any impact, the normal logic is to first determine whether there […]
