[ Two-Minute Linux Tips: Learn how to master a host of Linux commands in these 2-minute video tutorials ] To start with a very basic and not particularly useful command, you could run watch -n 5 date and see a display with the current date and time that updates every 5 seconds. As you likely have guessed, the -n 5 option specifies the number of seconds to wait between each run of the command. The default is 2 seconds. The command will run and update a display like this until you stop it with a ^c.To read this article in full, please Continue reading

Time to stock up on memory; prices to fall 20% this quarter

Contract prices for server DRAM are expected to fall by more than 20 percent this quarter over the same period in 2018, even more than the earlier forecast of 15 percent, reports DRAMeXchange, a division of TrendForce.The demand outlook remains weak due to high inventory levels, seasonal buying patterns, a tapering in demand, and uncertainties over the U.S-China trade war and the possibility of tariffs.Mark Liu, senior analyst at DRAMeXchange, said the main reason for price decline is because DRAM makers are having difficulty reducing inventory. The DRAM suppliers’ fulfillment rate went from 90 percent last quarter to 120 percent in this quarter, which means there is an oversupply.To read this article in full, please click here

TL;DR: Check out create-cloudflare-worker.

At Quintype, we are continually looking for new and innovative ways to use our CDN. Quintype moved to Cloudflare last year, partly because of the power of Cloudflare Workers. Workers have been a very important tool in our belt, and in this blog post we will talk a little bit about our worker development lifecycle.

Cloudflare Workers have drastically changed the way we architect and deploy things at Quintype. Quintype is a platform that powers many publishers, including many high volume ones like The Quint, BloombergQuint, Swarajya, and Fortune India. An average month sees hundreds of millions of page views come through our network.
