Edge computing in 2022: Double-digit growth

Worldwide spending on edge computing is expected to reach $176 billion in 2022, an increase of 14.8% over last year, according to new figures from analyst IDC.Edge computing started out rather modest in its use cases but has quickly expanded across industries and scope. Five years ago an edge network was a few mid-range servers in a ruggedized container. Now Nvidia and Lenovo are deploying GPU-based AI systems.How to choose an edge gateway “If we have learned anything over the last two years, the ability to quickly adapt to rapidly changing conditions is critical to business success. Organizations investing in edge computing combined with AI and modern application design will have an advantage when it comes to tackling whatever challenge comes next,” according to Dave McCarthy, research vice president for Cloud and Edge Infrastructure Services at IDC.To read this article in full, please click here

Using the Linux look command to select lines from files

The look command on Linux can be handy for selecting particular lines from text files with sorted contents. Let's look into how it can be used and where you might run into some problems.Case sensitivity If you type a command such as "look unix", you should see this:$ look unix UNIX Unix unix Notice that, because no file was specified in the command shown, look reverts to using the words file on the system (probably /usr/share/dict/words or whatever that points to). Also notice that it finds the three lines in the file even though the argument for the command has only lowercase characters. The command is case-insensitive when you don't provide a file name and instead allow it to default to the words file.To read this article in full, please click here

Nvidia acquires Bright Computing

Remember when Nvidia was a gaming-card vendor? That doesn’t seem all that long ago but now it’s a full-blown enterprise high-performance computing and AI company that happens to sell videogame cards - if you can actually find them.Its latest move is the acquisition of Bright Computing, a maker of Bright Cluster Manager software that controls the configuration of clustered HPC systems, including Nvidia’s own DGX servers and HGX systems made by OEMs and ODMs, plus clusters from other manufacturers. The clusters of servers are linked by high-speed networks into a single unit.[Get regularly scheduled insights by signing up for Network World newsletters.] If the deal goes through, Bright Cluster Manager will become a part of Nvidia’s Enterprise Products Group. Nvidia has no intention of keeping Bright Cluster Manager for itself, and by being a part of the Nvidia channel, it gives Bright an opportunity to expand and grow its market.To read this article in full, please click here

The truth about Linux true and false commands

True and false are common concepts in all forms of computing. They’re critical to Boolean logic after all, but did you know that true and false are also commands on Linux? Do you know how to use them?The simplest explanation is that the true command generates an exit code of 0 and that the false command generates an exit code of 1. This explanation, however, doesn’t provide much detail on how these commands can best be used.In this post, we’ll look at how the true and false commands work and how you might put them to use on the command line or in your scripts.To read this article in full, please click here

Microsoft issues a fix for on-prem Exchange mail servers

Microsoft Exchange admins got a bit of a rude surprise as the new year rang in, with a “latent date issue” striking the on-premises versions of Exchange Server 2016 and 2019 that saw emails queued up instead of being distributed to inboxes.The problem lay with Exchange’s malware scanning engine, however, Microsoft took great pains to emphasize in a blog post from the Exchange team that the problem relates to a date-check failure with the new year and it not a failure of the antivirus scanning engine itself, nor is it a security issue.To read this article in full, please click here

Fractured edge-gateway market starts to heat up

As the enterprise edge expands to encompass everything from the factory floor and oil rigs to solar arrays and retail stores, overcoming the challenges of processing, managing, and securing data traffic close to the source has become a top priority for many organizations.Enter edge gateways. These devices process data from sensors, monitors, industrial controllers, and other devices at the edge, passing only actionable information over the WAN to cloud and enterprise data centers while weeding out bandwidth-hogging noise—for example, pressure sensors on an oil rig showing everything is fine.

When quantum computers forget: Overcoming decoherence

There’s no point in having a quantum computer if it’s not smokin’ fast; otherwise it’s way too much trouble, what with all the subzero temperatures and instability and such. So it’s always newsworthy when somebody sets a new standard for quantum computing processing speeds, even if quantum computers are far from common commercial use.In this case that somebody is IBM, which recently announced its newly developed quantum computing processor, called Eagle, has broken the 100-qubit barrier. IBM[Get regularly scheduled insights by signing up for Network World newsletters.] Fusion boldly (if clumsily) says it views Eagle “as a step in a technological revolution in the history of computation.” (It sounds like an algorithm wrote that sentence! Is this where you’re leading us, Big Blue? A quantum future of incoherent techspeak?)To read this article in full, please click here

Splitting files on Linux by context

The csplit command is unusual in that allows you to split text files into pieces based on their content. The command allows you to specify a contextual string and use it as a delimiter for identifying the chunks to be saved as separate files.As an example, if you wanted to separate diary entries into a series of files each with a single entry, you might do something like this.$ csplit -z diary '/^Dear/' '{*}' 153 123 136 In this example, "diary" is the name of the file to be split. The command is looking for lines that begin with the word "Dear" as in "Dear Diary" to determine where each chunk begins. The -z option tells csplit to not bother saving files that would be empty.To read this article in full, please click here

New Year’s resolutions for Linux sysadmins in 2022

As the new year gets off to a start, it's always a good idea to commit to some changes that might improve your life or make your work more rewarding. So, here are some suggestions for Linux sysadmin resolutions for 2022.Learn some new commands Even after using Linux for more than 30 years, I often find myself discovering some command that I didn't know about or didn't realize how much I could do with it. 2021 was the first year that I used the cheat command or used the --help option for commands more often that I read their man pages. I also started using the bpytop command fairly often. And, whenever I ran across a command I wasn't previously familiar with, I took the time to look it up, install it (if needed) on one or more of my Linux systems and play with it. Considering that I'm seeing nearly 2,000 files just in /usr/bin on my Fedora system, I'm not surprised that, even after 30+ years, I'm not familiar with all of them.To read this article in full, please click here

Schneider Electric publishes data-center sustainability framework

French IT giant Schneider Electric has published a five-part framework meant to serve as a guide to minimizing the environmental impact of data center operations.Schneider is billing the framework as an industry first, but the company does specialize in power systems management so it’s not all self-congratulations. The framework is designed to help operators make their sites more environmentally friendly regardless of how far along they are in sustainability efforts.Data center power consumption is on pretty much everyone’s radar to varying degrees. Researchers have estimated that data centers worldwide account for between 1% and 2% of all power consumption. For hyperscalers like Google and Facebook, as well as for enterprises, power savings is equal parts benefit to the bottom line and being good corporate stewards.To read this article in full, please click here
