Keeping SSH sessions alive with systemd-inhibit

In my Home Lab network I use my desktop for most of my development. Since it’s a desktop and not a server it abides by the power policy setting I have selected. This works great unless I’m working a remote session from anything else such as my laptop, cell, etc. My usual workflow is just an ssh session with tmux, where I wake up the system by issuing a Wake on LAN (wol) from an always on server. After the typical timeout around 30 mins the system goes to sleep which drops the session and forces

Rendezvous Hashing Explained (2020)

Rendezvous hashing is an algorithm to solve the distributed hash table problem - a common and general pattern in distributed systems. There are three parts of the problem: Keys: unique identifiers for data or workloads Values: data or workloads that consume resources Servers: entities that manage data or workloads For example, in a distributed storage system, the key might be a filename, the value is the file data, and the servers are networked data servers that collectively store all of the f

Condor Technology to Fly "Cuzco" RISC-V CPU into the Datacenter

Once a hyperscaler or a cloud builder gets big enough, it can afford to design custom compute engines that more precisely match its needs. It is not clear that the companies that make custom CPUs and XPUs are saving money, but they are certainly gaining control and that is worth something. Arm made a push based on the power-efficient nature its architecture, and Nvidia has become a key player in AI with its powerful GPUs and now its “Grace” Arm server CPUs. A reinvigorated AMD has given system

Nvidia Just Suffered a Huge Blow in China

For years, the Chinese tech industry has been dependent on the US and its allies for the advanced semiconductors — colloquially known as "chips" — that undergird the AI industry. As the "AI race" has heated up to a fever pitch, chips have become its chief commodity — and bottleneck, as companies compete to build out the infrastructure they believe will run a multi-trillion dollar market. At the moment, the undisputed leader in AI chips is Nvidia, which has rocketed it from modestly-sized gamin

iPhone Fold and iPhone 18 Pro set to get faster mobile data

Sure, the iPhone 17 lineup hasn’t even shipped yet, but that doesn’t stop the news cycle rolling on. A new report details the chipset we can expect to find inside the iPhone Fold and the iPhone 18 Pro models. This will of course include the A20 chip, the first to be made using a 2-nanometer process, but the report suggests we can expect mobile data speeds to be faster thanks to a new Apple modem chip … A20 chip for iPhone Fold and iPhone 18 The iPhone 17 models use TSMC’s 3nm process, but the

Waymo's Robotaxis Are Heading to Nashville. Everything to Know About the Self-Driving Service

Self-driving cars are slowly becoming less sci-fi and more real-world as companies like Waymo, the autonomous arm of Google's parent Alphabet, expand into more cities.

Fed Chair Powell Says AI Probably a Factor in Concerning Unemployment Rates

The Fed decided to cut interest rates on Wednesday, citing a weak labor market as the reason. The latest jobs report showed that U.S. employers only added 22,000 jobs in August, down from the 79,000 in July, showing a dramatic slowing in hiring. It was the worst August report since the pandemic and it got the Federal Reserve Board concerned.

How to motivate yourself to do a thing you don't want to do

We have an air bike in our basement. If you are unfamiliar with air bikes, they are similar to stationary bikes with foot pedals but also have handles you push and pull with your arms.
