Blockchain Firm Offchain Labs Releases Alpha Of Open-Source Scaling Solution
New Jersey-based Offchain Labs has announced the launch of the Alpha 2 version of its scaling solution that can be easily integrated to any Etherum application.
Led by a former White House Deputy Chief of Technology and a team of U.S.-based academics, Offchain Labs aims to make smart contracts more private, secure, and scalable using a combination of protocol design, incentives, and virtual machine architecture. The firm has invented Arbitrum, a blockchain agnostic Layer 2 scaling solution that incentivizes parties to agree off-chain how a virtual machine would act in order to improve transaction throughput, speed, and privacy.

As Crypto Markets Go Cold, Who Will Pay for Open-Source Code?
Earlier this year IBM purchased Red Hat, the oft-referred to model for how open source can thrive, for $34 billion.
Long the consultant to enterprises, IBM is going through a transitional period as a business and needs a boost. Red Hat’s open-source software offers IBM the ability to better compete in cloud services offered by Amazon, Microsoft and Google.
Why is this important? Red Hat is one of the most name-checked examples of how open-source software can be successful. It is often used as an example of how championing open source can lead to business success. This is particularly pertinent to the cryptocurrency ecosystem, where open-source ethos rule the technology.

Open Source Smart Smoker Brings The Heat (Slowly)
Conceptually, cooking on a grill is simple enough: just crank up the flames and leave the food on long enough for it to cook through, but not so long that it turns into an inedible ember. But when smoking, the goal is actually to prevent flames entirely; the food is cooked by the circulation of hot gasses generated by smoldering wood. If you want a well-cooked and flavorful meal, you’ll need the patience and dedication to manually keep the fuel and air balanced inside the smoker for hours on end.
[...]
Ultimately, this project boils down to tossing a bunch of temperature sensors at the problem. The software developed by [HackersHub] takes the data collected by the five MAX6675 thermocouples and uses it to determine when to inject more air into the chamber using a PWM-controlled fan at the bottom of the smoker. As an added bonus, all those temperature sensors give the user plenty of pretty data points to look at in the companion smartphone application.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
