‪“‬In what way is JS any more maintainable than CSS? How does writing CSS in JS make it any more maintainable?”

‪Happy to chat about this. There’s an obvious disclaimer that there’s a cost to css-in-js solutions, but that cost is paid specifically for the benefits it brings; as such it’s useful for some usecases, and not meant as a replacement for all workflows. ‬

‪(These conversations always get heated on twitter, so please believe that I’m here to converse, not to convince. In return, I promise to listen to you too and change my opinions; I’ve had mad respect for you for years and would consider your feedback a gift. Also, some of the stuff I’m writing might seem obvious to you; I’m not trying to tell you if all people of some of the details, but it might be useful to someone else who bumps into this who doesn’t have context)‬

So the big deal about css-in-js (cij) is selectors.

During GSoC I was able to accomplish the following: optimize part of the ipred functions and implement tile threading support.

Can we create a smart contract VM on nodejs using Dat?

Ethereum is a trustless network of VMs which run smart contracts submitted by users. It uses proof-of-work to synchronize state across the network, and has every node execute the contracts in order to verify the state's validity. Each transaction is stored in the blockchain for replayability. Read more about it here.

Ethereum's "trustless network" model has some disadvantages:

• Transaction processing is slow - it maxes at roughly 25tx/s right now for all contracts combined.
• Every transaction costs money to execute.
• The entire blockchain state must be shared across the computing network.
• No private transactions.

Tuning Intel Skylake and beyond for optimal performance and feature level support on Linux:

Note that on Skylake, Kabylake (and the now cancelled "Broxton") SKUs, functionality such as power saving, GPU scheduling and HDMI audio have been moved onto binary-only firmware, and as such, the GuC and the HuC blobs must be loaded at run-time to access this functionality.

Enabling GuC and HuC on Skylake and above requires a few extra parameters be passed to the kernel before boot.

Instructions provided for both Fedora and Ubuntu (including Debian):

Note that the firmware for these GPUs is often packaged by your distributor, and as such, you can confirm the firmware blob's availability by running:
