The Symptoms

WavePy is a Python 3.12-based ocean wave data processing system running in a Conda environment called wave312. During recent development, the process started vanishing without warning. No Python traceback, no error logs, just gone.

The last line of the log always stopped at the memory monitor output for scipy.interpolate.griddata:

2026-03-02 01:23:43,251 - MemoryMonitor - INFO - [MEM][interpolate_unstruct_grid:hsig:20260302_060000] RSS: 1440.44 MB

After that, nothing. No traceback, no exception. It was a classic C extension segfault.

SSH is an application-layer encrypted network protocol. It’s used for remote login, remote command execution, and data transfer.

It consists of an SSH client and an SSH server. There are many implementations, with OpenSSH being the default on Ubuntu. The client is ssh, and the server is sshd.

Requirements

I want to connect to my home PC from my iPad Pro anytime, anywhere.

R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.

You can embed an R code chunk like this:

summary(cars)
##      speed           dist       
##  Min.   : 4.0   Min.   :  2.00  
##  1st Qu.:12.0   1st Qu.: 26.00  
##  Median :15.0   Median : 36.00  
##  Mean   :15.4   Mean   : 42.98  
##  3rd Qu.:19.0   3rd Qu.: 56.00  
##  Max.   :25.0   Max.   :120.00
fit <- lm(dist ~ speed, data = cars)
fit
## 
## Call:
## lm(formula = dist ~ speed, data = cars)
## 
## Coefficients:
## (Intercept)        speed  
##     -17.579        3.932

Including Plots

You can also embed plots. See Figure 1 for example:

This is a post written in plain Markdown (*.md) instead of R Markdown (*.Rmd). The major differences are:

1. You cannot run any R code in a plain Markdown document, whereas in an R Markdown document, you can embed R code chunks (```{r});
2. A plain Markdown post is rendered through Blackfriday, and an R Markdown document is compiled by rmarkdown and Pandoc.

There are many differences in syntax between Blackfriday’s Markdown and Pandoc’s Markdown. For example, you can write a task list with Blackfriday but not with Pandoc:
