I maintain a heterogeneous MSP environment for backup which consists of a collection of sh scripts (they mostly run on FreeBSD) with (c) notes dating back to 2004, with 5 authors, 4 of whom are no longer my cow-orkers. As the unfortunate 5th, I am still doing tweaks to catch edge & corner cases >20y after the 1st author had the idea that rsync, shell, mt, & standard POSIX tools could be assembled into a decent free backup world.
Use Python. Or Go. Or even Perl.

speaking as someone who uses bash all the time, it’s a fully equipped programming language and you absolutely should not use it as one because it’s made of footbullets. Use Python. For extra sysadmin flavour, make it a Python script that does all the hard bits with a system call to bash.

how do you like them apples?
#cndpoli #Canpoli #Poilievre

A dweeb of a man is standing outdoors, wearing a dark blue blazer over a matching blue shirt. He is holding a red apple in his right hand, taking a bite. His left hand is holding a pair of sunglasses. The background shows a blurred natural setting with greenery and wooden posts, suggesting an orchard or a similar outdoor environment. The man has short, graying hair and is wearing a ring on his left hand. The lighting is natural, indicating it is daytime. The Sod - Pierre Poilievre- lost the Ca…

Impact of curved elements for flows over orography with a Discontinuous Galerkin scheme
We present a quantitative assessment of the impact of high-order mappings on the simulation of flows over complex orography. Curved boundaries were not used in early numerical methods, whereas they are employed to an increasing extent in state of the art computational fluid dynamics codes, in combination with high-order methods, such as the Finite Element Method and the Spectral Element Method. Here we consider a specific Discontinuous Galerkin (DG) method implemented in the framework of the de…

Ilford FP4 @ ISO 64 **English:** This black-and-white image shows a solitary young tree standing in an open area, possibly a park or garden. The tree is slender with sparse branches and few leaves, indicating it might be early spring or late autumn. The background features a tall residential building, contrasting the natural element of the tree with the urban environment. The ground around the tree is covered with grass, and the overall atmosphere is calm and serene. **Chinese:** 这张黑白照片展示了一棵孤…
Ilford FP4 @ ISO 64 **English:** This black-and-white photograph depicts a young tree planted in a rural landscape. The tree is centrally located and appears to be supported by a small mound of soil at its base. The surrounding area is grassy with patches of bare earth. In the background, there are more young trees, suggesting a plantation or orchard setting. The terrain is slightly hilly, and the overall scene conveys a sense of early growth and cultivation. **Chinese:** 这张黑白照片描绘了一棵种植在农村景观中的…
Ilford FP4 @ ISO 64 **English:** This black-and-white photograph depicts a natural landscape with various trees and shrubs. The foreground features a prominent pine tree with long needles and a distinctive shape. The background includes a mix of other trees and vegetation, creating a dense and lush environment. The lighting suggests it might be a sunny day, with shadows cast on the ground, adding depth to the scene. The overall atmosphere is one of natural beauty and tranquility. **Chinese:**…
Ilford FP4 @ ISO 64 **English alt text:** A black and white photograph of a small branch with a few buds and droplets of water on it. The background is blurred, making the branch the focal point of the image. **Chinese alt text:** 一张黑白照片，展示了一根带有几个花蕾和水滴的小树枝。背景模糊，使树枝成为图像的焦点。

Precision farming powered by K3s and TensorRT
Aurea Imaging is an AgTech scaleup focusing on precision farming in orchards. By retrofitting our TreeScout sensor package to their tractors, farmers are able to collect data about their orchard down to the tree level as they perform other tasks. Using onboard stereo cameras, the tractor’s high-precision GPS, a machine-vision pipeline running in real time on the device, and cloud-based analytics, this data is turned into maps used by other agricultural machines that enable the grower to utili…

Efficient and scalable atmospheric dynamics simulations using non-conforming meshes
We present the massively parallel performance of a $h$-adaptive solver for atmosphere dynamics that allows for non-conforming mesh refinement. The numerical method is based on a Discontinuous Galerkin (DG) spatial discretization, highly scalable thanks to its data locality properties, and on a second order Implicit-Explicit Runge-Kutta (IMEX-RK) method for time discretization, particularly well suited for low Mach number flows. Simulations with non-conforming meshes for flows over orography can…

Men are shaving off their eyelashes on TikTok. Here’s why that might be a bad idea
It could take up to three or four months for your eyelashes to grow back to their typical length.
