Resizing images on the Linux command line

The convert command from the ImageMagick suite of tools provides ways to make all sorts of changes to image files. Among these is an option to change the resolution of images. The syntax is simple, and the command runs extremely quickly. It can also convert a image from one format to another (e.g., jpg to png) as well as blur, crop, despeckle, dither, flip and join images and more.Although the commands and scripts in this post mostly focus on jpg files, the convert command also works with a large variety of other image files, including png, bmp, svg, tiff, gif and such.Basic resizing To resize an image using the convert, you would use a command like this:To read this article in full, please click here

Intel revises its XPU strategy

Intel has announced a shift in strategy that impacts its XPU and data-center product roadmap.XPU is an effort by Intel to combine multiple pieces of silicon into one package. The plan was to combine CPU, GPU, networking, FPGA, and AI accelerator and use software to choose the best processor for the task at hand.That’s an ambitious project, and it looks like Intel is admitting that it can’t do it, at least for now.Jeff McVeigh, corporate vice president and general manager of the Super Compute Group at Intel, provided an update to the data-center processor roadmap that involves taking a few steps back. Its proposed combination CPU and GPU, code-named Falcon Shores, will now be a GPU chip only.To read this article in full, please click here

Why it makes sense to converge the NOC and SOC

It’s been 17 years and counting since Nemertes first wrote about the logic of integrating event response in the enterprise: bringing together the security operations center (SOC) and network operations center (NOC) at the organizational, operational, and technological levels. Needless to say, this has not happened at most organizations, although there has been a promising trend toward convergence in the monitoring and data management side of things. It’s worth revisiting the issue.Why converge? The arguments for convergence remain pretty compelling: Both the NOC and SOC are focused on keeping an eye on the systems and services comprising the IT environment; spotting and understanding anomalies; and spotting and responding to events and incidents that could affect or are affecting services to the business. Both are focused on minimizing the effects of events and incidents on the business. The streams of data they watch overlap hugely. They often use the same systems (e.g. Splunk) in managing and exploring that data. Both are focused on root-cause analysis based on those data streams. Both adopt a tiered response approach, with first-line responders for “business as usual” operations and occurrences, and anywhere from one to three tiers of escalation to more senior engineers, Continue reading

After China’s Micron ban, US lawmakers urge sanctions on chips from CXMT

The US Commerce Department should put trade restrictions on Chinese memory chip maker Changxin Memory Technologies (CXMT), say lawmakers on the US House of Representative’s Committee on China.The comments come in the wake of the Chinese government ban on the use of some Micron chips in certain sectors, citing concerns that the products pose a significant security risk to the country’s key information infrastructure supply chain.However, these claims are “not based in fact” White House press secretary Karine Jean-Pierre told reporters, adding that the Department of Commerce was engaged directly with the PRC (People's Republic of China) to detail the administration’s views on the ban.To read this article in full, please click here

Intel launches Agilex FPGA for smart networking

Intel has launched a field-programmable gate array—Agilex 7 with R-Tile—that features PCIe 5.0 and CXL capabilities for processing networking workloads.The Agilex FPGA is primarily used in smartNICs that offload the processing of network traffic from the CPU, thus freeing up CPU capacity for other tasks. Intel sees Agilex playing a role in data centers, telecommunications, and financial services, among other high-traffic industries.Agilex is a rebranding of Intel’s Stratix and Arria FPGA lines that involves renumbering, with Agilex 3 being the low-end and Agilex 9 the high-end. So Agilex 7 is not the seventh generation of the chip but is the second most powerful processor in the family.To read this article in full, please click here

BrandPost: The role of network access control in Zero Trust security

By: Eve-Marie Lanza, Senior Security Solutions Marketing Manager, HPE Aruba Networking.An advertising campaign from the 1980s posited that peanut butter and chocolate were, “two great tastes that taste great together.” While confectionary tastes may vary, there’s no denying that some things just work better together. When it comes to IT security, network access control, and Zero Trust security are like peanut butter and chocolate—great on their own, undeniably better together.Network access control vs. Zero Trust securityNetwork access control and Zero Trust security are not the same, but they are related.To read this article in full, please click here

5G network slices could be vulnerable to attack, researchers say

5G promises increased speed, lower latency, and support for a significantly larger number of connected devices. But the growth in devices and in new applications that will ensue also will expand the attack surface, offering new opportunities for malicious actors to take advantage of security gaps.Plus, as with any new technology, there is a great deal of potential for misconfigurations, errors, and unpatched vulnerabilities while companies are still learning how to deploy and secure 5G at scale.About 75% of communication service providers worldwide said that they had experienced up to six security breaches of 5G networks within the past year, according to a November 2022 survey by GlobalData and Nokia. Half of the respondents said that they experienced an attack that resulted in the leakage of customer data, and nearly three quarters said that an attack had caused a service outage.To read this article in full, please click here

Frontier still reigns as world’s fastest supercomputer

For the third time in a row, Frontier is ranked number one among the world’s fastest supercomputers, and it remains the only whose fastest speed exceeds one exaFLOPS.At 1.194 quintillion floating point operations per second (FLOPS), Frontier kept its ranking with more than double the top speed of its nearest competitor, according to the list compiled by TOP500, which issues the rankings twice a year. A quintillion is 1018 or one exaFLOPS (EFLOPS).The number two machine, Fugaku, maxed out at 442.01petaFLOPS. A petaFLOPS is 1015 FLOPS.Two competitors in the top 10 improved their speeds since the last ranking period that ended in November 2022, but not nearly enough to even draw close. Those two—LUMI and Leonardo—rank third and fourth, respectively.To read this article in full, please click here

IT pros worry about network data being fed to AI tools

As more IT organizations apply artificial intelligence (AI), machine learning (ML), and so-called AIOps technology to network management, network data is critical to success. AI/ML technology requires more and more data to learn individual networks, derive insights, and offer recommendations. Unfortunately, many organizations encounter problems when trying to feed network data to these AI tools.In other words, network teams need to modernize their approach to network data before they embrace AI technology.Enterprise Management Associates recently surveyed 250 IT professionals about their experience with AI/ML-driven network management solutions for a report, “AI-Driven Networks: Leveling up Network Management.” It found that data problems are the number-two technical challenge they encounter when applying AI/ML to network management. Only network complexity is a bigger technical issue.To read this article in full, please click here
