Built on a 2 nanometer technology node, the processor’s design will contain 11 high-performance cores operating at more than 5.7 GHz, AI inference accelerators for in-transaction fraud detection, a dedicated on-chip data processing unit for I/O acceleration, and a large cache architecture for demanding enterprise workloads. The chip is architected to not contain separate Arm and IBM cores: each processor core can natively execute Arm and IBM Z, or Arm and LinuxONE, instructions concurrently while prioritizing the platform’s established performance, security, encryption, and availability characteristics. IBM Z and LinuxONE platforms are capable of scaling to hundreds of cores and tens of terabytes of memory.

↫ IBM press release

IBM is still doing some amazing chip architecture design. ServeTheHome has more details of how this works:

A key choice here is that IBM implemented AArch64 in full hardware rather than through translation. This design uses a little-endian Arm implementation alongside big-endian z/Architecture, with AArch64 v9.3, SVE and SVE2 support, and 2,792 implemented AArch64 instructions. IBM also claims Arm SystemReady compliance, which matters for how much off-the-shelf Arm software this core can absorb. This is absolutely crazy technology. Arm software sees a native Arm processor. Arm runs unmodified, out-of-the-box, and onto a standard Arm platform. IBM said the 2792 AArch64 instructions are more than twice the Z instructions. IBM made a funny quip about “reduced” in RISC.

This is bonkers technology. We can only dream of this ever serving a home.

It’s always a special day on OSNews when Haiku has a new release. While OSNews was founded in 1997, it wasn’t until 2001, when Eugenia took over and relaunched the site, that we really got going. Eugenia came from BeNews, a popular BeOS news website, which shut down in the wake of Be, Inc’s infamous “focus shift” away from BeOS as a general purpose desktop operating system. BeOS continues to have a special place on OSNews ever since.

Today marks the release of Haiku R1/beta6, the first official Haiku release in two years. As such, this new beta covers a monumental amount of progress since beta5, progress I’ve reported on diligently. The highlights of this new beta include a port of Firefox (including branding) and many of its forks, much improve support for Qemu, a new memory allocated largely based on the one from OpenBSD, and improved support for various filesystems. Of course, there’s a massive list of performance improvements, memory management changes, as well as a truly massive number of new application ports.

It’s important to note, as I usually do, that while these Haiku beta releases serve as patches of calm in rough seas, Haiku is generally stable and capable enough that using the project’s nightly releases is usually a totally acceptable way of installing and running the operating system. If you’re not comfortable running nightly releases, however, and haven’t tried Haiku since the previous beta, you’re in for a massive overall improvement.

Everybody loves Haiku.

Ring has a new way to protect your videos. It's developed an encryption method called TAKE, short for Throw Away the Key Encryption, that the Amazon-owned company says will protect your videos without traditional end-to-end encryption. TAKE limits when and why Amazon's cloud can access those videos, while still providing features like smart alerts for people and packages, AI-powered video search, and video descriptions.

The feature is rolling out gradually starting in September, regardless of whether you have a subscription, and will become the default encryption for all Ring customers.

TAKE arrives during a year of intense scrutiny for R …

Digg basically became a front page for Reddit as it circled the drain

Digg was a high flying news aggregation site from the early web 2.0 era that still exists today, but really in name only. It serves as a cautionary too for why high profile websites tend not to make major changes overnight. A major update, Digg v4, introduced August 25, 2010, caused the site to implode over the course of about 6 weeks during the late summer of 2010. Contemporary tech CEOs would do well to read up on it lest they repeat history.

Digg went from concept to being worth $200 million in about three years and was more popular than Reddit, which is now a $15 billion company. One ill fated change wiped out 90% of its value and its user base in a matter of six weeks.

If you ask someone to define Digg in six words or less, here’s what they would likely say: The thing we used before Reddit.

Today, Reddit claims to be the front page of the Internet. Arguably, during Digg’s heyday, Yahoo was still the front page of the Internet, but Digg was the heir apparent.

If there’s one defining factor about 3D printing you have to account for when you’re making a design, it’s probably layer adhesion. Sure, there are a lot of factors to consider, but having the z-axis of your part dramatically weaker than x- and y- is a pretty big deal in a whole lot of applications. [I Changed a thing] changed a thing to fix that — namely, he changed his 3D printer by strapping a couple of lasers to it. That’s the kind of hack we like to see!

What the lasers are doing is a very simple idea: they’re pre-melting the last-laid-down-layer just under the nozzle so that molten plastic is meeting molten plastic to create a much stronger joint than you get when you extrude onto an already-cold layer. The second layer keeps the hotspot warmer longer, which also helps the bond. The resulting parts are not purely isotropic, but he’s getting breaking strain along the z-axis of ABS that’s up to 94% of what he’s measuring in the x direction, while PLA still rates at 77.9%. That’s compared to 60% and 41%, for un-lasered samples, respectively. If you watch the video, you’ll get all the details for the printing process and can see more test data.

These lasers look like a game-changer, but their mass might slow down the fast coreXY printers that are so popular these days. If you don’t want to slow down, remember that changing your layer patterns can boost a print’s strength on its own.
