Kyndryl has launched an infrastructure-management service that promises to help connect and integrate enterprise resources.Kyndryl Bridge integrates existing tools, partnerships, intellectual property, and processes the company has amassed through years of delivering infrastructure services and uses it to provide as-a-service capabilities and applications that help control and manage enterprise infrastructure.Enterprises have invested in heterogeneous tools and management platforms that don’t integrate the data they gather, and Kyndryl Bridge connects, aggregates, and centralizes that siloed performance data, said Antoine Shagoury, Kyndryl’s chief technology officer. "Then, we use our engineering expertise and AI to analyze the results in real time to provide operations personnel the intelligence they need to keep systems running at peak performance," he said.To read this article in full, please click here
On Linux, the apropos command helps identify commands related to some particular term. It can be helpful in finding commands you might want to use—especially when you can’t remember their names.For example, if you couldn’t remember the command to display a calendar or put your shell to sleep for a short period of time, you could try these commands:$ apropos calendar
cal (1) - display a calendar
$ apropos sleep
sleep (1) - delay for a specified amount of time
usleep (1) - sleep some number of microseconds

Seagate has upgraded its Exos Application Platform storage arrays with a new ASIC RAID controller that doubles performance and adds what Seagate calls self-healing to preserve data on defective hard disks.The Exos X models are a rebranding of the old Exos AP line. The chassis can hold a mix of traditional hard disks as well as SSDs. It comes with software that automatically moves “hot” data, which is being frequently accessed, to SSDs, while less used, “cold” data is moved to the hard drives.There are three Exos X products, defined by their size and drive-bay count. The 2U12 is a 2U chassis with 12 3.5-inch hard-drive bays; the 2U24 with is a 2U chassis has 24 drive slots; and the 5U84 with 84 slots in a 5U chassis. It has all of the standard connections: SAS, network attached SAS, Fibre Channel up to 32G, iSCSI up to 25G and a 10GBASE-T option as well.To read this article in full, please click here

The idea is to offer business customers the ability to use cutting-edge new capabilities—for example, automated inspection for manufacturing, or high-level analytics for healthcare providers—without using global cloud services that might take data out of the country or having to implement that type of system completely in-house.To read this article in full, please click here
Personally, I always try to avoid filenames with blanks, usually by filling those places where less blank-phobic people would use them with underscores or hyphens. The filenames are still easy to decipher, and I don’t have to trouble myself with enclosing them in quotes when I want to use them. As a result, some of my files look like this:locking-accts
Lost_World
I also rarely add .txt file extensions to the end of text files unless I plan to share them with my Windows system.Use quotes
When blanks in file names are preferable for any reason, however, there are several easy ways to work with them. To reference existing files, you can enclose the filenames in single or double quotes. In fact, you can make this easier by starting with a quote mark, typing as much of the filename as needed to differentiate it from other files and then pressing the tab key to initiate filename completion. For example, typing the portion of a filename as shown in the example below and then pressing tab should add the rest of the filename to the “file n” beginning:To read this article in full, please click here
A growing number of organizations are drawing an invisible line around their internet-connected resources in an effort to keep attackers at bay. Called software-defined perimeter (SDP), it is based on the relatively simple idea of throwing a virtual barrier around servers, routers, printers, and other enterprise network components.The goal of SDP is to protect networks behind a flexible, software-based perimeter. "Advantages include stronger security and greater flexibility and consistency," says Ron Howell, principal SD-WAN and SASE architect at IT and business consulting firm Capgemini Americas.To read this article in full, please click here

Using a series of commands to copy a file to multiple locations or a number of files to a single location can be time-consuming, but there are options to speed up the process. This post explains some of them.Multiple commands like these can to copy a single file to a series of directories on your system:$ cp myfile dir1
$ cp myfile dir2
$ cp myfile dir3
One way to make the task easier is typing the first command and then repeat the command by only specifying the needed changes. This method relies on whether the file or directory names are similar enough to substitute only some portion of the names.
