Manipulating the Ubuntu dock to keep favorite apps handy

If you're a Linux user, you are undoubtedly familiar with the "dock"--that column of icons lined up on the side of your screen that includes important applications, your favorites. It allows you to open the applications simply by left clicking on one of the icons. Sandra Henry-Stocker / IDG But did you know that you can add or remove applications from your dock and sometimes even change the location of the dock on your screen? This post shows you how to make these changes on Ubuntu.To read this article in full, please click here

Data-center outages: Causes are changing, report says

A new survey by the Uptime Institute found that power issues are becoming less of a problem for data center operators, but networking and software issues are emerging as an increasingly bigger problem.The Uptime Institute's third Annual Outage Analysis notes that while improvements have been made with technology and availability, outages remain a major industry, customer, and regulatory concern. The report also shows that the overall impact and direct and indirect cost of outages continue to grow. When asked about their most recent significant outage, more than half of respondents reported an outage in the past three years and estimated its cost at more than $100,000; among those respondents, almost one-third reported costs of $1 million or above.To read this article in full, please click here

5 top open-source infrastructure projects

Open source software has been a key underpinning of enterprise IT for years, so it’s no surprise that it’s helping to drive the infrastructure part of the equation forward just as much as application development.Some projects are much more influential than others, and here are five that are doing the most to help enterprise infrastructure keep pace with the demands of an ever-more sophisticated operating environment.OpenStack OpenStack is notable in part for being an open-source competitor to the most important proprietary virtualization software on the market—VMware’s VSphere. For the basic task of virtualizing servers into a flexible pool of computing resources, the difference appears to be ease of use—it’s simpler to use VMware when there isn’t a lot of in-house virtualization or private-cloud expertise.To read this article in full, please click here

Juniper: Managing the complexity of future networks

Juniper Networks Manoj Leelanivas Like most of its competitors, Juniper Networks is leaning hard on developing all manner of software components—from automation to intent-based networking—in order to address the changing needs of enterprise-network customers. Moving into the software realm is no small task as Juniper has to integrate products from a number of acquisitions including Mist, 128 Technologies, Apstra, and NetRounds. At the same time it continues to develop its own Junos software and invest in key open-source projects such Software for Open Networking in the Cloud (SONiC) among other undertakings. Network World talked with Manoj Leelanivas, Juniper’s executive vice president and chief product officer about the company’s software directions and how it is preparing for challenges of the future. Here is an edited version of that conversation. To read this article in full, please click here

Linux commands for testing connectivity and transfer rates

There are quite a few tools that can help test your connectivity on the Linux command line. In this post, we'll look at a series of commands that can help estimate your connection speed, test whether you can reach other systems, analyze connection delays, and determine whether particular services are available.ping The ping command is the simplest and most often used command for doing basic connectivity testing. It sends out packets called echo requests and are packets that request a response. The command looks for the responses and displays them along with how long each response took and then reports what percentage of the requests were answered.To read this article in full, please click here

Round-up of Nvidia GTC data-center news

With a few dozen press releases and blog posts combined, no one can say that Nvidia’s GPU Technology Conference (GTC) is a low-key affair. Like last year’s show it is virtual, so many of the announcements are coming from CEO Jen-Hsun Huang’s kitchen.Here is a rundown of the most pertinent announcements data-center folks will care about.Two Ampere 100 offshoots Nvidia's flagship GPU is the Ampere A100, introduced last year. It is a powerful chip ideal for supercomputing, high-performance computing (HPC), and massive artificial intelligence (AI) projects, but it’s also overkill for some use cases and some wallets.So at GTC the company introduced two smaller scale little brothers for its flagship A100, the A30 for mainstream AI and analytics servers, and the A10 for mixed compute and graphics workloads. Both are downsized from the bigger, more powerful, and more energy-consuming A100.To read this article in full, please click here

VMware, Dell split to form independent firms

After many months of wrangling, Dell Technologies says it is spinning off its ownership of VMware to create two standalone companies.While it gives both companies more financial freedom, the new relationship should have no immediate effect on enterprise customers, but that could come down the road.VMware CEO Gelsinger moves to Intel Dell has had an 81% equity ownership of VMware since its 2016, $67 billion purchase of  EMC, which owned VMware. Under terms of the planned spin-off, VMware will distribute a cash dividend of $11.5 - $12 billion to all VMware shareholders, which includes about $9.7 billion to Dell Technologies, the companies stated.To read this article in full, please click here

Taking control of your Ubuntu desktop

You may have a lot more control over your Ubuntu desktop than you know. In this post, we'll look into what you should expect to see by default and how you can change that.Most Linux desktops start out charmingly uncluttered. They display a handful of icons on an attractive background. These include shortcuts for launching applications, generally along the left side or bottom of the screen, and maybe another icon or two in the otherwise open area.The uncluttered desktop is generally a good thing. You can open folders using your file manager and move around to any group of files that you need to use or update. By changing a setting on Ubuntu (and related distributions), however, you can also set up your system to open with a specified set of files in view – and you don't have to move them into your Desktop folder to do so.To read this article in full, please click here

10 of the best ways to get help on Linux

Just because Linux appeals to the nerdiest of nerds doesn't mean that it can't be extremely helpful for those who don't want to spend a lot of time delving into the technical details of how to use various commands. In fact, Linux provides a series of tools that can help anyone master the command line or just get the task at hand done more quickly and efficiently. This post covers 10 of the best options.man pages You can always go to the man pages to answer usage and syntax questions you might have on a Linux command. Just type "man" followed by the name of the command (e.g., man ps), and you'll get a lot of descriptive information. On the other hand, if you really just want to see some examples of how to use a particular command, the content of a man page might be a lot more than you want to comb through. In the remainder of this post, I'll explain some other options for finding the command that you need and learning how to use it.To read this article in full, please click here

Nvidia announces a 2023 launch for an HPC CPU named Grace

Nvidia kicked off its GPU Technology Conference (GTC) 2021 with a bang: A new CPU for high performance computing (HPC) clients--its first-ever data-center CPU--called Grace.Based on the Arm Neoverse architecture, NVIDIA claims Grace will serve up to 10-times better performance than the fastest servers currently on the market for complex artificial intelligence and HPC workloads.But that’s comparing then and now. Grace won’t ship until 2023, and in those two years competitors will undoubtedly up their game, too. But no one has ever accused CEO Jen-Hsun Huang of being subdued.Nvidia made a point that Grace is not intended to compete head-to-head against Intel's Xeon and AMD's EPYC processors. Instead, Grace is more of a niche product, in that it is designed specifically to be tightly coupled with NVIDIA's GPUs to remove bottlenecks for complex AI and HPC applications.To read this article in full, please click here

How to shop for a colocation provider

If you want to move assets out of your data center but for whatever reason can’t shift to the cloud, a colocation, or “colo” for short, is increasingly a viable option.Colo is where the client buys the compute, storage, and networking equipment but instead of putting it into their own data centers, they put them in the data center of a hosting company. They still own and manage the hardware, but they don’t have responsibility for manage the facilities—heating, cooling, lighting, physical security, etcNow see "How to manage your power bill while adopting AI" As such, colocation facilities attract considerable interest from enterprises. IDC puts the 2020 US colocation market at $9 billion, growing to $12.2 billion by 2024 for a compound annual growth rate (CAGR) of 8%. Grand View Research estimates the global data-center colocation market size was valued at $40.31 billion US dollars in 2019 and is expected to grow at a CAGR of 12.9% from 2020 to 2027. Gartner makes the bravest prediction, saying that by 2025, 85% of infrastructure strategies will integrate on-premises, colocation, cloud, and edge delivery options, compared with 20% in 2020.To read this article in full, please click here

Major League Baseball makes a run at network visibility

Major League Baseball is taking network visibility to the next level.“There were no modern network-management systems in place before I came in. It was all artisanally handcrafted configurations,” says Jeremy Schulman, who joined MLB two years ago as principal network-automation software engineer.

Microsoft documents its liquid-immersion cooling efforts

Last week I told you about an immersion-cooling firm called LiquidStack being spun off from its parent company, the China-based server vendor Wiwynn. The story mentioned how Microsoft was experimenting with immersion cooling, and now Microsoft has pulled back the curtain on the whole show.It’s been trying out immersion cooling for two years but is now going full throttle, at least at its Quincy, Washington, data center. Situated in the middle of the state, the city of Quincy is tiny—just 6,750 as of 2010—but the Columbia River cuts through it, making it ideal for a hydropower-based data center, and there are several data centers in this tiny town.To read this article in full, please click here
