Arcade floors once filled with the clatter of joysticks as players guided a barbarian, a sorceress, and a dwarf across fantasy landscapes filled with beasts and bandits. SEGA’s 1989 side-scrolling fighter Golden Axe delivered pure power fantasy in short, intense bursts. Now those same characters are returning in a full animated series that puts their personalities under closer scrutiny while keeping the monster-smashing spirit intact.

All ten episodes will premiere on Paramount+ on a Wednesday in September, specifically on the 16th. CBS Eye Animation Productions, Sony Pictures Television, and Original Film collaborated on the new show, which is animated by Titmouse. Mike McMahan and Joe Chandler collaborated to create the series and created the first episode; Chandler also serves as showrunner, and a handful of SEGA executives are on board to ensure the license is handled properly.

My Arcade Streets of Rage Micro Player: Retro Gaming, 2 Sega Games in 1

• 🎮 Officially licensed SEGA titles. Take on the roles of vigilante heroes battling through waves of enemies to bring down a corrupt crime syndicate.
• 🎁 Collector’s Item: A must-own for collectors and fans of SEGA games. Titles Included are Streets of Rage, and Streets of Rage 2.
• High resolution 2.75″ full color display.

We pick up with the classic trio of Ax Battler, Tyris Flare, and Gilius Thunderhead, who are pushed back together since, as you might expect, Death Adder has a horrible habit of remaining alive. Things get problematic as soon as Hampton Squib joins the party; the guy has spent his entire life thinking of adventure, but when the going gets tough, he realizes he is poorly unprepared. Now they must work together and use their various skills to save Yuria.

Matthew Rhys adds a lot of snark to Gilius Thunderhead, a foulmouthed combat dwarf with questionable personal habits. Danny Pudi plays Hampton Squib, and the poor guy’s passion greatly exceeds his actual ability. Lisa Gilroy transforms Tyris Flare into a snappy-mouthed fighting sorceress who is equally likely to give you lip as she is to blast you with magic. Liam McIntyre portrays Ax Battler as a hunky barbarian with a code and a heart of gold. Carl Tart plays Chronos “Evil” Lait, a human panther with a theatrical streak that borders on absurd.

With Star Trek: Lower Decks and Solar Opposites under his blet, McMahan has already demonstrated his ability to balance large laughs with real passion for the content. Golden Ax never had to be fancy or detailed to be spectacular. Players simply wanted to crush things with a large ax or start fires with their magic. The animated series retains the same simple delights while adding a touch of character conflict to give it some actual depth, and Death Adder is just the type of challenge that keeps you going back for more.

So, if you used to pump quarters into the arcade game back in the day, you can rediscover the old crew with fresh voices and fleshed-out personalities, while everyone else can enjoy a comprehensive fantasy adventure that doesn’t take itself too seriously. All 10 episodes are released at once, allowing you to form your own opinion on how well everything works out.

With Private Safety Processing, AI biz promises discreet, automated prompt surveillance

OpenAI appears to have found a way to balance AI model safety with commitments to retain no customer data, a feat rival Anthropic hasn’t yet managed. For orgs concerned about who has access to their data, this could be a game-changer.

The free-spending AI biz on Wednesday announced Private Safety Processing, a mechanism for automatically scanning customer model interactions for safety risks without violating Zero Data Retention (ZDR) commitments.

Anthropic meanwhile has noted that its implementation of ZDR includes a non-zero amount of data retention for covered models – currently Mythos 5 and Fable 5. For commercial customers using  ZDR as of June 9, 2026, “we are requiring limited data retention and review as part of our safety work. Prompts submitted to, and outputs generated by, covered models are retained for 30 days to support our safety work, on every platform where these models are offered.”

OpenAI, Anthropic, and various other AI model makers agree some oversight of rapidly advancing model capabilities is a good idea. The devil is in the details, which in the case of Private Safety Processing have not yet been published.

Generally speaking, both companies have similar policies for commercial customers using lower tier models.

“For Anthropic API users, we automatically delete inputs and outputs on our backend within 30 days of receipt or generation,” Anthropic says, with exceptions for certain services, ZDR agreements, and legal/policy enforcement. 

For OpenAI ChatGPT Business customers, “Your workspace admins can control how long your data is retained. Any deleted or unsaved conversations are removed from our systems within 30 days, unless longer retention is required by law, or is reasonably necessary to protect our services or any third party from harm.” That 30-day policy also applies to OpenAI’s API in most cases.

When Anthropic detects usage violations, it may retain model inputs and outputs for up to two years and trust and safety classification scores for up to seven years. 

The major distinction now is ZDR and how the two frontier AI companies define that concept. 

Anthropic has a ZDR exception for those using its top models.

For OpenAI ZDR deployments, customers may control the infrastructure or they may choose to store data on OpenAI infrastructure, where OpenAI says it will soon provide customer-controlled encryption keys.

“In both cases, automated systems can identify potential misuse and return limited safety signals without exposing the underlying prompts or responses to OpenAI personnel,” the company explains in its post.

Anthropic allows more room for human review when content is flagged by its automated systems. “By default, no Anthropic personnel can read your retained conversations,” the company says in its documentation. “Human review can occur only through a controlled access path—for example, when content is flagged by our automated trust and safety systems for potential harm.”

OpenAI’s human intervention scenario is narrow – in the event child exploitation material is detected. 

With the addition of Private Safety Processing – to be explained in more detail next month, OpenAI insists – whatever data gets stored is unavailable to company personnel.

“Private Safety Processing builds on the automated protections already used in ZDR and other deployments,” the AI biz explains. “Existing ZDR-compatible safety systems evaluate interactions individually. Private Safety Processing extends those protections across related interactions, allowing automated systems to identify patterns without OpenAI personnel having access to retained customer content.”

What’s noteworthy about this beyond the privacy commitment is the company’s expanded interest in “related interactions.” That suggests OpenAI’s safety assessment is looking not just at prompt input and output but tool use and network data signals.

Keeping AI interactions and data flows private has become a major concern. Apple has its Private Cloud Compute. Google has its Private AI Compute. Nvidia offers Confidential Computing. Even Meta, not exactly known for its commitment to privacy, talks up its Private Processing for AI. And much of the interest in running local AI models reflects a desire to keep sensitive data safe from potentially prying service providers and adversaries.

OpenAI may have read the room well with its celebration of private model policing, but as Matthew Green, associate professor of computer science at Johns Hopkins University, observed recently, “private inference isn’t private enough.”

Green notes that AI agents – models connected to tools – often rely on sensitive data when they act on our behalf, and while private inference may protect some part of the data flowing to and from AI agents, there are many other gaps in the system.

“At the risk of saying more obvious things, the difference between a helpful private agent, a corporate advertising bot, and a government spy comes down mainly to a matter of prompting, and maybe a bit of model fine-tuning,” he wrote. “Once you combine private data access and the ability to send messages, there is essentially no technical protection that private inference alone can offer.” ®

We’ve seen with some headphones releases that some efforts get leaked deliberately, others leak unfortunately, but in the case of Sennheiser, it likes to keep things under wrap.

Much like Gandalf, Sennheiser’s headphones arrive precisely when they mean to, and in this case it’s Momentum True Wireless 5 that’s arrived on the scene, a few months after its bigger over-ear sibling, the Momentum 5 Wireless.

And Sennheiser’s big selling point about its new flagship true wireless is that it’s providing the signature Momentum sound in your pocket, marking them out as its most advanced true wireless earphones yet.

Here’s what the new Momentum True Wireless 5 is bringing to the table.

Dolby Atmos with Head tracking

Not exactly a new feature on the market, but Sennheiser has joined others in its support for Dolby’s spatial audio. This is not, however, Sennheiser’s own take on spatial audio in the vein of Bose’s Immersive Audio, it’s simply Dolby Atmos Music with the option of enabling head-tracking so audio stays attached to your and follows your movement

They arrive in lots of lovely colours

I do have a moan about headphones arriving in just black and white at launch, but Sennheiser has glitzed up its latest true wireless with a selection of different colours.

There’s a choice of Cream, Graphite, Copper, Denim, and Lavender, all of which look quite swish and stylish.

But that’s not all on the design front. You may have noticed that the overall appearance has change, with the new Momentums taking on a more rounded, oval shape that Sennheiser has told me is there to aid noise isolating fit with a better seal and improved levels of comfort. The earbuds also protrude for the ear less (for those that don’t like bulky earbuds), and the ear-tip nozzle has been redesigned to reduce ear pressure in the ear canal.

These change look to make the Momentum True Wireless 5 the most comfortable in the series, though as always, we’ll have to see if that measures up when we review the new pair.

An all-new ANC system

A new version provides the chance to firm up a few areas that might have been lacking. It’s not as if the Momentum True Wireless 4‘s ANC was bad in any way, but perhaps it wasn’t quite at the level of Sony and Bose. That’s an area of performance Sennheiser would like to redress with these wireless earbuds.

Along with the redesigned ear-tip nozzle, there’s a dedicated four-microphone array “to maximise noise cancelling performance”, while deliver the series most “natural-sounding, real-time transparency mode to date”.

For calls, an area we did think could have been improved, Sennheiser has enlisted the help of all eight system sensors, combining the six mics mentioned above with two bone-conduction voice accelerometers with an AI speech extraction algorithm to isolate your voice in loud and busy areas.

You can replace the batteries

We often hear from audio brands that they’ve made the earbuds so small that they can’t allow for owners to replace the batteries themselves. They have to be sent back for service.

Sennheiser scoffs at that idea.

You can replace the batteries in both the earbuds and the charging case, ensuring these headphones can last as long as you want them to. Battery life without ANC is 12 hours, and with noise cancellation on, you can expect it to be around half as much.

It’s competitively price

Similarly to the Momentum 5 Wireless, the Momentum True Wireless 5 aren’t looking to put too big a hole in your wallet. At £249.99 / €299.90 / $299.95 / $479.95, they cost less (in the UK at least) than the Bose QuietComfort Ultra Earbuds II and the JBL Tour Pro 3, and around the same as the Technics AZ100 and Sony WF-1000XM6 cost when they launched.

In the US, they all had an RRP of around the same, but of course, the rest of the competition has been out for a while, so more than likely the Sennheiser will command a higher price while the others get reduced in the usual sales.

• More than 2,500 organizations, including Cisco, Samsung, AWS, Airbus U.S. Space & Defense, Thales, and the London Stock Exchange Group, have credentials harvested during a supply-chain attack on LiteLLM
• LiteLLM was not directly hacked by the hacking group TeamPCP, which found their way in thanks to a compromised build of an open-source security scanner
• Some of the credentials still work, nearly five months after the original breach, indicating that there is still a persistent security risk until they are changed

Security firms CloudSEK and Hudson Rock have claimed more than 2,500 organizations have had credentials harvested in a supply-chain attack on LiteLLM.

LiteLLM, an open source gateway which translates API calls for over 100 large language models into a single OpenAI-compatible format, was not directly compromised in the attack, as hackers targeted a known vulnerability in Aqua Security’s Trivy.

I used the M1 MacBook Air as my primary laptop for nearly four years. During that time, I used it for everything from drafting news stories to editing photos for reviews, working from flights to weekend workcations. And if there was one thing that earned more compliments than the slim chassis and overall design, it was the speakers.

Whether I am watching an Apple keynote on YouTube, a stand-up comedy special in my room, a movie with a couple of friends on a workcation, or simply hearing the charging chime and notification sounds, the M1 MacBook Air always sounded remarkably clear and surprisingly loud. Be it the ghosts screaming in The Conjuring, the web-swinging sounds during an intense Spider-Man action sequence, or Chandler’s one-liners from Friends, it never really sounded like audio coming from a laptop.

That changed when my M1 MacBook Air suddenly refused to turn on in June 2026, forcing me to buy the 13-inch M5 MacBook Air with 16GB of RAM and 512GB of storage. Everything about the M5 MacBook Air feels like an upgrade, as it should, considering it’s five generations newer, except the speakers.

The four-speaker “upgrade” that sounds worse than two

On paper, the M5 MacBook Air should sound better. It replaces the M1’s two-speaker setup with a four-speaker system. In practice, though, it doesn’t sound as loud or as rich as the M1 MacBook Air. 

What you actually get instead is a thin, almost hollow midrange, a shrill emphasis on high frequencies, and minimal low-end presence, the kind of sound signature that makes dialogue clear but leaves music and movies feeling flat and lifeless. There’s no fullness to it, no weight behind a bassline or an explosion, just treble doing all the heavy lifting.

I noticed it almost immediately. During setup, I heard a couple of audio cues and instinctively tried to turn up the volume, only to realize it was already maxed out. A few days later, a friend who had always complimented the M1 MacBook Air’s speakers asked a simple question: “What’s wrong with the speakers?” I told her what I thought might be happening.

What’s happening here?

The M1 MacBook Air had two upward-firing speakers, so the sound reached your ears directly. On the newer Air, Apple hides the speaker system inside the hinge, meaning the sound reflects off the display before reaching you. 

That likely contributes to the difference; bouncing sound off a fixed surface instead of firing it directly at you tends to scatter the low frequencies first, which would explain exactly why the bass disappears while the treble stays sharp, even shrill, in comparison.

Sitting across the table, she also felt the speakers didn’t project as well. To make sure it wasn’t just my ears playing tricks on me, I compared my M5 MacBook Air side by side with a friend’s M1 MacBook Air, and the difference was immediately obvious. The M5 sounded clear, but the M1 was noticeably louder and fuller, the kind that you’d want to use to play music in a room.

As it turns out, I wasn’t the only one hearing it. Digging through Reddit, I found several people who’d reached the same conclusion after comparing the two machines side by side. One user on r/macbook, who claims to own four MacBooks, writes that the “M1 actually sounds the loudest of them all.”

Others say the M5 MacBook Air’s speakers sound cleaner, while another user describes them as being “too much optimized for normal speech/dialogue clarity.” That lines up almost perfectly with my experience. Voices sound crisp, but there’s noticeably less low-end punch.

What’s missing is the loudness and richness that made the M1 MacBook Air’s speakers so impressive at full volume.

Can software actually fix this? 

Since the hardware itself isn’t changing, I spent some time seeing whether macOS could compensate for any of that missing warmth and fullness through software, and two built-in tools are worth knowing about, both tucked inside the Music app.

The Equalizer, found in the taskbar under Window > Equalizer, lets you manually boost or cut specific frequency bands, and it includes a Preamp slider at the top that governs overall output level before the individual bands even kick in. Nudging the Preamp up genuinely makes the M5’s speakers sound louder, and pairing that with a boost to the lower-frequency sliders helps mask some of that missing bass presence. 

However, if you push the Preamp too far, especially combined with an already maxed system volume, you’ll start hearing audible distortion and clipping, a crackly, strained quality that’s arguably worse than just accepting the speakers’ limitations. 

The second tool, Sound Enhancer, lives under Music > Settings > Playback, and it works completely differently from the Equalizer. Rather than adjusting specific frequencies, it widens the perceived soundstage by subtly altering how bass and treble are processed together. Basically, it tricks your ears into hearing a broader, more spacious soundstage than two closely spaced hinge-mounted speakers can naturally produce. 

Turning it on made a noticeable difference for me; music felt less pinched and centered. It won’t add bass weight the way boosting the Equalizer’s low end does, but it meaningfully improves how “big” the sound feels. Between the two, I’d start with Sound Enhancer for everyday listening, then layer in a modest Preamp and bass boost through the Equalizer. 

Just don’t expect either one to fully replace what the M1’s upward-firing speakers did for free.

Is it actually a dealbreaker?

No. Most people probably won’t notice the difference, especially if they’re coming from an older Windows laptop or an entry-level notebook. But if you’re upgrading from an M1 MacBook Air, the difference is surprisingly easy to notice. And once you hear it, it’s hard to ignore.

This is more of a PSA feature. The M5 MacBook Air offers a generational performance upgrade, but while the screen experience is only marginally better, the speakers are a noticeable downgrade. If you’re going with the 15-inch M5 MacBook Air, however, that offers a better six-speaker system. And if upward-firing speakers are a must-have, you’ll need to step up to one of Apple’s MacBook Pro models.

PA-RISC emulation matters for data center modernization because it allows enterprises to decouple mission-critical HP-UX and MPE/iX applications from end-of-life physical hardware, enabling immediate migration to modern x86 servers or cloud infrastructure with zero code changes and minimal operational risk.

Quick Take

The PA-RISC Dilemma in the Modern Data Center

Developed in the 1980s and widely deployed through the 2000s, Hewlett-Packard’s Precision Architecture RISC architecture was a cornerstone of enterprise computing. Powered by the proprietary PA-RISC processor family—including 32-bit and 64-bit CPU designs such as the PA-7000 and PA-8000 series—these systems were engineered for high-availability database management, manufacturing execution, financial clearing, and enterprise resource planning. These environments ran either HP-UX or MPE/iX, operating systems custom-tailored to the underlying silicon.

However, HP officially phased out sales of PA-RISC systems in 2008 and ceased technical support around 2013 as the industry shifted toward Itanium and standard x86-64 server architectures. Today, organizations maintaining physical PA-RISC footprint in their data centers face several compound operational risks:

• Component Scarcity and System Failure: Physical board-level components—including power supplies, bus backplanes, memory modules, and specialized SCSI host bus adapters (such as LSI 53C8xx controllers)—are no longer manufactured. Maintenance teams are forced to rely on secondary, refurbished markets with uncertain reliability.
• Unplanned Downtime and Slow Recovery: Thermal degradation in aging silicon and mechanical drive failures increase the frequency of system outages. Without vendor patch support or hot-swappable replacement chassis, MTTR (Mean Time to Repair) stretches from hours into days.
• Data Center Resource Drain: Legacy multi-cabinet rack units occupy extensive floor space and draw disproportionate amounts of power. In an era where modern facilities prioritize data center power efficiency, maintaining kilowatt-heavy legacy cabinets strains utility budgets and air-handling units.
• Security and Compliance Gaps: Outdated hardware platforms cannot host modern encryption modules, automated compliance audit agents, or enterprise security monitoring tools required under PCI-DSS, HIPAA, or ISO 27001 standard frameworks.
• Loss of Institutional Knowledge: System administrators and hardware technicians skilled in vintage enterprise Unix systems and MPE console debugging are retiring, leaving organizations without in-house emergency support.

How PA-RISC Emulation Works Under the Hood

Hardware emulation bridges the gap between obsolete physical systems and modern infrastructure by changing the physical layer beneath the operating system rather than altering the software application. Implementing enterprise-grade PA-RISC emulation creates an instruction translation layer that presents a virtualized PA-RISC hardware platform directly to the guest operating system.

According to digital preservation research, virtualizing or emulating technical platforms allows organizations to preserve exact binary operational behavior while isolating applications from physical hardware decay. The emulation software layer handles instruction translation and hardware mapping through three primary subsystems:

1. Dynamic CPU Instruction Translation: The emulator intercepts guest PA-RISC machine instructions (PA-1.1 or PA-2.0 execution calls) and dynamically translates them into equivalent x86-64 instruction sequences executed by modern Intel Xeon or AMD EPYC processors.
2. Memory and Endianness Management: PA-RISC uses big-endian byte ordering, whereas modern x86 CPUs operate on little-endian architecture. The software emulation layer continuously translates memory references, registers, and memory management unit (MMU) address mappings transparently.
3. Virtual I/O and Peripheral Mapping: Physical disk arrays, tape drives, network interface cards, and serial controllers are mapped to virtual abstractions. For example, legacy SCSI storage controllers are mapped to virtual disk files residing on fast NVMe SAN arrays or enterprise cloud storage.

Because the emulation layer presents an identical virtual hardware abstraction to the operating system, the installed copy of HP-UX 11i or MPE/iX 7.5 booted within the emulator cannot distinguish the software environment from a physical server. The original kernel binaries, custom application code, databases, and configuration files remain completely untouched.

Core Benefits of PA-RISC Emulation for Modernization

When planning comprehensive data center modernization strategies, IT leadership must weigh speed, cost, and risk. Emulation provides a pragmatic middle path between maintaining fragile legacy hardware and executing high-risk application rewrites.

1. Rapid Infrastructure Consolidation

Emulation allows multiple multi-U physical server towers or heavy cabinet units (such as HP 9000 N4000 series or HP 3000 systems) to be virtualized onto standard 1U/2U rack servers or virtual instances. This physical consolidation frees up valuable data center floor space and enables integration into existing VMware, KVM, or bare-metal Linux host environments.

2. Slashed Energy and Cooling Overheads

Moving workloads from vintage multi-socket PA-RISC servers to dense x86 host hardware drastically lowers power consumption per computing cycle. Heat output decreases in tandem, reducing the load on data center HVAC systems and aligning IT operations with corporate sustainability mandates.

3. Zero Application Rewriting or Retraining

Full software refactoring or re-platforming projects routinely run over budget and take months or years to execute. Emulation executes existing binary code in place. end-users interact with identical application interfaces, workflow commands, and batch processes, eliminating the need for workforce retraining or operational process redesign.

4. Integration with Enterprise Disaster Recovery

Physical legacy servers often lack modern backup capabilities, relying on aging physical tape drives or manual image dumps. Once hosted in an emulated environment, guest operating systems gain immediate access to modern infrastructure tools: live VM snapshots, automated SAN replication, rapid recovery points, and cloud backup vaults.

5. Performance Upgrades via Modern Silicon

While dynamic instruction translation incurs software overhead, the sheer raw speed, higher cache capacity, and elevated clock rates of contemporary x86 CPUs mean emulated workloads often execute faster than they did on 20-year-old physical silicon.

6. Flexible Cloud Deployment Pathways

Modern emulation solutions are not limited to on-premises data centers. As documented in AWS Marketplace documentation for Charon-PAR, emulated PA-RISC platforms can run directly on cloud virtual instances (such as Amazon EC2 running enterprise Linux). This enables hybrid cloud integration without modifying core legacy software stacks.

Evaluating the Strategic Alternatives

Before committing to an implementation pathway, enterprise architects should contrast emulation against alternative legacy system migration strategies. A detailed comparison highlights the distinct trade-offs inherent in each approach:

Technical Trade-offs, Limitations, and Failure Modes

While emulation resolves immediate hardware exposure, engineering teams must evaluate specific technical edge cases during project planning. According to a detailed legacy hardware emulation analysis, understanding host dependencies is vital for a smooth transition.

• Proprietary Physical Interfacing: If the original PA-RISC server relies on specialized physical expansion cards—such as proprietary serial interface boards or custom non-standard PCI cards—those hardware devices cannot be physically plugged into modern x86 servers. The solution requires converting those hardware channels into network-attached serial gateways or IP-based emulated protocols.
• Host Sizing and CPU Core Oversubscription: Emulation relies on dedicated CPU resources for dynamic translation. Oversubscribing host CPU cores on hypervisors running heavy concurrent workloads can cause timing latency or degraded I/O throughput in the emulated guest OS. Dedicated CPU pinning or bare-metal host reservation is recommended.
• Storage Queue and Latency Tuning: Mapping virtual SCSI disks to modern storage requires proper host OS queue depth configuration. If disk image files reside on poorly configured network storage, asynchronous write spikes in HP-UX databases can trigger temporary disk wait timeouts inside the guest kernel.
• Vendor Licensing Constraints: While the application code remains unchanged, certain third-party software products running inside HP-UX bind their licenses to CPU serial numbers or specific hardware machine IDs. Engineers must audit application licensing mechanisms to ensure smooth re-licensing on virtualized hardware calls.

Understanding these virtualization and emulation techniques enables infrastructure teams to conduct pre-migration host sizing tests, mitigating latency issues before production cutover.
