How to use the Linux uniq command

In Linux, the uniq command can help find out the individual users who are logged into a given server, but it’s not a straightforward process.Yes, using the command on its own yields a list of who’s logged in, but it can list individual users more than once depending on what they’re doing.There are ways to get around this by sorting the results of uniq so they deliver only once the names of all the users. This 2-Minute Linux Tip video by Network World’s Unix as a Second Language blogger Sandra Henry Stocker shows how to do just that. Click below.

IBM closes $34B Red Hat deal, vaults into multi-cloud

IBM has finalized its $34 billion purchase of Red Hat and says it will use the Linux powerhouse's open-source know-how to enable larger scale customer projects and to create a web of partnerships to simplify carrying them out."A lot of our mutual clients are interested in doing a lot more," says Arvind Krishna, Senior Vice President, IBM Cloud & Cognitive Software in a blog post. "Many see this as an opportunity for us to create large industry ecosystems with other providers who are optimized on this common infrastructure. ...If Red Hat were to do this on their own, there would be a limit to how much they can scale. Together, we can put a lot more resources into optimizing other partners."To read this article in full, please click here

10 of the world’s fastest supercomputers

10 of the world's fastest supercomputersImage by Henrik5000 / Getty ImagesThe TOP500 ranking of the fastest supercomputers in the world was announced today, with absolutely no change in the computers ranking in the top10 since the last semi-annual rating in June. Outside the top 10, though, there were changes, notably that it’s harder for a supercomputer to get on the TOP500 list at all: The lowest ranking supercomputer now delivers 1.14PFlop/sec, up from 1.02PFlop/sec in June. Overall, the aggregate performance of the entire TOP500 list sits at 1.65 exaflops. Check out the rest of this slideshow to see details on the current top-10-ranking machines.To read this article in full, please click here

Study: Most enterprise IoT transactions are unencrypted

Of the millions of enterprise-IoT transactions examined in a recent study, the vast majority were sent without benefit of encryption, leaving the data vulnerable to theft and tampering.The research by cloud-based security provider Zscaler found that about 91.5 percent of transactions by internet of things devices took place over plaintext, while 8.5 percent were encrypted with SSL. That means if attackers could intercept the unencrypted traffic, they’d be able to read it and possibly alter it, then deliver it as if it had not been changed.To read this article in full, please click here
