A few days ago Intel compiler expert H.J. Lu landed an FMA-optimized log2 function for the GNU C Library that could yield up to a 69% performance improvement on tested Intel Skylake processors. Merged today to Glibc Git was another FMA-optimized function. H.J. Lu has continued his recent FMA optimization push for the GNU C Library by optimizing expm1, the function to return a value of an exponential minus 1. While the expm1 function may not be as common, testing again on Intel Skylake showed some nice improvements. The mean improvement was 24% better than the prior Glibc behavior before introducing…

In my colleague Jason Cipriani’s full review of the Pixel 7 Pro, he stated, “I can’t print the first thing that came out of my mouth after taking a 30x picture…”…
“One aspect of project leadership is figuring out how to best use each student’s skills,” says Engineer Nathan Hui. (Photo by Alex Matthews) Nathan Hui’s trajectory, for one, has been shaped by E4E for almost a decade. As a UC San Diego electrical engineering undergraduate, he found E4E more relevant to real problems than the autonomous airplane competitions he had tried. After working on aerial monitoring with cameras mounted on helium balloons for the San Dieguito River Valley Conservancy, he hit his stride when he joined the Radio Collar Tracking project, throwing himself into signal processing and drone integration, including…

Intel Meteor Lake S CPU engineering sampleA picture of an upcoming LGA1851 desktop CPU has made its way onto the internet. Though a picture of a CPU that’s a year or more from release isn’t particularly amazing, what is interesting is that it appears to be a Meteor Lake sample. While Meteor Lake-S was seemingly canceled, the existence of CPUs such as these tells us Intel got a long way down the Meteor Lake-S development path.The pictured CPU comes from @wxnod (via Videocardz). The CPU is definitely an LGA1851 sample as the notches near the edge of the chip align…

But the Watch X could reverse that trend with a number of significant new features, according to Gurman.Also: Every product we’re expecting…
Last year the Samsung Galaxy Z Flip4 received a below average 4/10 repairability score in PBKReviews’ disassembly video. How does the new Galaxy Z Flip5 fare? Much better actually, it got a 7.5/10. A major reason for this improvement is that Samsung used pull tabs for the two batteries whereas they were just glued in place last year. The small battery in the top half has 1,000mAh capacity, the one in the bottom half has 2,700mAh. The two batteries inside the Samsung Galaxy Z Flip5: 1,000mAh on top • 2,700mAh on bottom Various other parts have been…
