Logitech teamed up with the Genshin Impact team for a special edition of its slim wireless keyboard, and the result feels more thoughtful than most licensed gear. The G515 Kamisato Ayaka special edition model, priced at $69.99 (was $170), takes the standard low-profile TKL hardware and wraps it in a clean white design that nods to the character without turning the whole thing into a billboard. It stays subtle enough for daily use while still giving fans something distinctive to look at every time they sit down.

The keyboard itself measures only 22 millimeters at its tallest point, giving it a very thin profile, thanks mostly to the low-profile GL mechanical switches and a chassis that has been shortened significantly by the lack of a number pad. The end product is a really slimline device, with the white body featuring some really sleek light blue and lavender artwork down the edges, as well as swirling swirls and snowflake accents that pay homage to Ayaka’s cryo theme and her extremely graceful fan design. To accentuate the idea, the spacebar features a fan emblem and her name. The legends on the keycaps are designed in a way that uses a variety of colors that are readable even when the RGB lighting is turned on, since they do not clash with it.

The keycaps are made of double-shot PBT and have lasting legends, as well as a nice matte finish that does not shine with time. The casing provides significant sound dampening, as it is much quieter than many low-profile boards. The stabilisers are adequate for a prebuilt keyboard, though you may notice a slight vibration in the spacebar if you search for it. The feet on the bottom offer two tilt angles, allowing you to modify the slope without using any other equipment.

The 1.3-millimeter actuation point and 3.2-millimeter overall travel are beneficial for both typing and gaming, since the tactile brown switches in this edition are light and provide sharp feedback that registers rapidly without being mushy. The factory lubrication ensures that the keys remain smooth from day one. Going low profile also means less finger travel, which some individuals find less exhausting during extended sessions. The bad news is that there is no wrist rest in the box, so users who like one will have to either get used to the floating feel or create their own.

Wireless performance is based on Logitech’s LIGHTSPEED 2.4 GHz connection, which maintains a 1-millisecond report rate throughout gaming. There’s a Bluetooth option if you merely want to use it for light tasks or multi-device settings, as well as a USB-C wired mode that can be used as a backup or to charge. The provided dongle allows 2:1 pairing, which means that one USB port can handle both this keyboard and a compatible Logitech mouse. The battery should last for at least 36 hours with the RGB turned on, and much longer if you dim or turn off the lights. A USB-C to USB-A cable for charging is included in the box, along with the dongle and basic documentation.

The RGB illumination is fully incorporated into Logitech’s LIGHTSYNC system and looks stunning on the shine-through keycaps. Because this is a special edition, you’ll find some custom Ayaka-themed effects in G HUB, which focus on soothing blues and whites and subtle transitions rather than dramatic rainbow sweeps. The software allows you to build profiles, remap keys, and customize illumination by key or across zones. Onboard memory stores a few profiles, allowing the keyboard to work properly on different computers without the need to reload anything.

• The note also reaffirmed OpenAI’s commitment to AGI with a caveat: ensuring it benefits all of humanity

With modern AI solutions moving well beyond simple chatbots to agents and projected to evolve into operators, one could assume that the automation of everything is an eventual goal.

This, however, has been denied by OpenAI CEO Sam Altman and chief scientist Jakub Pachocki, who said the goal of the artificial intelligence research and deployment company is not to automate everything but to allow people to make better decisions as AI improves their lives.

The last thing you want to happen after dropping hundreds of dollars on a wearable is to discover that it doesn’t work with your body. But, that’s a fairly common problem people with wrist tattoos have been running into since the advent of smartwatches and fitness trackers. As countless posts on device support pages and Reddit have chronicled over the years, tattooed skin and the sensors used by wearables often don’t mix well.

One of the main issues people experience is with heart rate sensing. Wearables use a light-based technique called photoplethysmography (PPG) to measure heart rate. That’s the green light you see when you flip your device over. But, tattoos can get in the way of that light, messing with the readings. The other problem is wrist detection, which also uses lights to determine if the tracker is on a person’s wrist (along with an accelerometer and electrical sensors). Slap a fitness tracker on a wrist that’s covered by a tattoo, and the device may not register that it’s being worn at all, consequently requiring the wearer to repeatedly unlock the device whenever they want to interact with it.

It might seem a bit silly that technology advanced enough to respond to gesture controls and provide personalized sleep coaching would be stumped by a bit of pigment, but the tattoo issue isn’t just a baseless gripe that consumers have latched onto. Device makers have acknowledged it and advised buyers to avoid putting their trackers on top of tattoos.

“Tattoos (ink, pattern, saturation) can block the heart rate sensor’s light, causing inaccurate or missing readings,” Garmin notes on a support page. “For best performance, wear the watch on skin that is free of tattoos if possible.” Apple has issued similar notices going back to the release of the first Apple Watch.

Is there a solution?

People with tattoos have devised sorts of workarounds to get the most out of their smart watches and fitness trackers, though none are exactly ideal. The simplest? If the inside of your wrist isn’t tattooed (or at least has larger areas of clear skin), you can position the device there instead of on top of the wrist. Similarly, if your other wrist is tattoo-free, wear the device on that one. But if you’ve grown used to wearing a watch on a certain wrist for years, it’s going to feel pretty weird to change it up.

As a quick fix, some people swear by epoxy bottle cap stickers or layering pieces of clear tape, either of which are placed over the sensors and inexplicably correct the problem for a lot of wearers. Reusable accessories designed to work the same way have seen some success too. There’s also the option of using a chest strap if accurate heart rate tracking is all you’re after — and if you don’t have chest tattoos. Again, though, this isn’t the most comfortable or convenient way to use a wearable in most situations day-to-day. 

Ultimately, it’ll continue to be an issue until the sensors these watches and fitness trackers rely on are improved to account for skin variations like tattoo ink. Likewise, light-based sensors have been found to be less reliable for people with dark skin, highlighting a need for more diversity in the research and development of this type of technology.

Anecdotally, it seems like Google’s Pixel Watch 4 might be much better at handling tattooed skin than its predecessors. There were rumors of Samsung introducing an update a few years back to improve things in this area too, but the complaints of tattooed Galaxy Watch users would suggest otherwise.

More research is needed

Identifying the problem is theoretically the first step to solving it, but unhelpfully, the reality is that how much tattoos interfere with sensor readings isn’t consistent from case to case. A study published in 2025 attempted to quantify the difference in readings taken from devices worn over tattooed skin versus non-tattooed skin, and while it did find the former suffered inaccuracies, the results were mixed.

The researchers used the Polar Verity Sense and armband, outfitting participants with one device over a tattoo plus one on the same arm in an area without a tattoo. Participants also wore a Polar H10 chest strap heart rate monitor to establish a baseline, as this style of wearable is considered to be more accurate. Over the course of a day, they were monitored when at rest, walking at their own pace and jogging.

This revealed that the presence of the tattoos did have an impact on heart rate readings, but it was dependent on the wearer’s activity level, “with the greatest effect observed at rest and variation decreasing as exercise intensity increases.” And in some cases, the researchers note, “the presence of an arm tattoo did not affect the heart rate validity measurement at all.” There are a number of variables that must be taken into account — like ink color, saturation and depth — and as it stands today, there just hasn’t yet been enough research down to the nitty-gritty of the problem to bring about a solution.

Owners of original PlayStation consoles have watched their disc drives age for decades. Lasers fade. Games start to skip or fail to load altogether. Replacement drives grow scarce and expensive. A new device called ArcStation steps in with a direct solution. It replaces the entire optical drive assembly inside the console with a compact circuit board that loads games from an SD card instead. No discs stay necessary after setup. The change keeps the original hardware intact and authentic while removing the most common point of failure.

Installation is mercifully simple: simply unplug and open the case with a single Phillips screwdriver, and you’re done. Owners then carefully remove the old drive, flip over to the shiny new board, and adjust two little DIP switches to match the region settings on their console. Once that’s done, simply plug in the short cables provided, which go into the exact same locations as the originals. You will not need to apply any solder or make any lasting modifications to the motherboard. Instead, the new board sits well on the existing posts inside the casing thanks to a 3D manufactured mount that also accommodates both the larger “fat” PlayStation models and the handy tiny PSOne. A simple test boot with the lid remaining open will ensure that the old Sony logo and boot animation are back in action. Put the case back on, and you’re finished.

PlayStation®5 console – 1TB

• PlayStation 5 Console – 1TB, includes wireless controller, 1TBSSD, Disc Drive, 2 Horizontal Stand Feet, HDMI cable, AC power cord, USB cable, printed…
• 1TB of Storage, keep your favorite games ready and waiting for you to jump in and play
• Ultra-High Speed SSD, maximize you play sessions with near instant load times for installed PS5 games

Once inserted, the board appears as soon as you turn on the console and displays a very clean small menu on a tiny built-in LED screen. Users just copy their game files to a normal SD card formatted in either FAT32 or exFAT. It is not an issue to have CUE/BIN pairs, BIN files on their own, or ISO pictures on there; the board can handle them all. You can keep the games in folders or subfolders if you like, as this is all about organization. Simply hit the refresh button in the menu, and the board will scan your card and generate a list for you. Then simply press the title button with your controller, and the game will launch immediately on the original hardware. In terms of load timings, they’re not far off from what you’d get from an actual CD, and there’s even a special option for early motherboard revisions that can shave even more off.

The reason this works so well is that it accurately mimics the behavior of the original CD-ROM drive, down to the radio frequencies that the console expects. Games that generally look for modchips or copy protection will not even blink an eye. You get region-free access on all PS console generations, including the legendary PSOne. If you’re playing a game with multiple discs, the board will usually handle the queue for you. You can even build a manual queue of up to six discs and move between them as needed; simply press the button next to the SD slot while keeping an eye on the LED display.

Save games are moved to virtual memory cards that are kept directly on the SD card; each game has its own dedicated file, so storage never runs out like it did on the old physical cards. You can attach the virtual card to either slot 1 or 2 on the fat models, but be careful because some older systems cannot handle it. Owners can access the menu without having to turn off the console by specifying a button combination on the controller, which is far more convenient than fiddling around in the settings. The tiny PSOne differs from the others in that it cannot use virtual memory cards or the game reset combo due to its completely different internal layout, but it can still use all other functionalities. Some additional options on the main menu allow you to adjust video settings, switch to a light or dark theme, receive sound cues, have the console auto-start the previous game you played with a slight delay, and even display the game title from either a database or what is actually on the folder name.

Pre-orders began at the end of May at a reduced price of roughly 140 euros. Shipping is expected in September, but fingers crossed it will arrive sooner. The kit contains all of the wires required for both the fat and slender models, as well as the board, which is pre-mounted for ease of installation. There has been thorough testing on over a hundred titles, and the results on the fat models have been remarkably consistent, even after extended gaming sessions.

Market intelligence platform Klue has publicly confirmed a recent security incident that allowed threat actors to steal OAuth tokens used to connect to customers’ Salesforce environments, as the new “Icarus” extortion group publicly claims the attack.

The disclosure comes after cybersecurity firms Huntress and ReliaQuest detailed how attackers abused compromised Klue Battlecards integrations to steal Salesforce CRM data from multiple organizations.

In a statement published this week, Klue CEO Jason Smith confirmed that the company discovered unauthorized activity on June 12 affecting part of Klue’s integration infrastructure.

“On June 12, we identified unauthorized activity affecting a portion of Klue’s integration infrastructure. Since then, we’ve been working alongside trusted cybersecurity experts to understand what happened, support our customers, and restore the connections you rely on,” wrote Smith.

“Our investigation determined that an attacker gained access through a compromised legacy credential associated with an integration service. The attacker used that access to obtain OAuth tokens used to connect Klue with certain third-party platforms, including Salesforce, and subsequently accessed data within a number of connected customer environments.”

The company says there is currently no evidence that customer content stored directly within the Klue platform was impacted and that the incident was limited to third-party integrations.

Klue says it immediately revoked affected credentials and tokens, removed unauthorized code, disabled impacted integrations, launched an investigation, and notified law enforcement. The company also confirmed it engaged CrowdStrike to assist with the response.

ReliaQuest and Huntress found that the attackers used stolen OAuth credentials associated with Klue integrations to access customer Salesforce environments and conduct large-scale data theft.

ReliaQuest observed attackers generating OAuth tokens and using Python scripts to query Salesforce’s API for extended periods, as data was stolen.

Huntress later disclosed that its own Salesforce environment was affected by the Klue breach and that the stolen data included business contacts, sales communications, pricing information, and other records.

Icarus claims responsibility

While BleepingComputer and Huntress previously linked the incident to the Icarus extortion operation, the threat actors have now publicly claimed responsibility on their data leak site.

“As you’ve probably already heard, Klue.com has been impacted by us recently. A number of other companies’ Salesforce instances, which were partners to Klue, were exfiltrated,” reads the Icarus post.

The threat actors went on to pressure Klue and affected organizations to contact them through the Session messaging platform to prevent the leaking of stolen data.

The post comes after BleepingComputer previously reported that the attacks were linked to Icarus, after sources shared extortion emails sent to affected organizations. Huntress also independently connected the operation to Icarus through Session Messenger IDs used in the extortion emails and the group’s data leak site.

Since then, additional victims have disclosed that they were affected by the attacks, including Recorded Future, Tanium, Jamf, Sprout Social, Gong, and Insurity.

Almost all say the incident led to the theft of data from their Salesforce instances and did not affect their platforms, infrastructure, payment information, or internal systems.

Several organizations warned that the stolen business contact information could be used in follow-on phishing, social engineering, and extortion campaigns and urged customers to be vigilant.

Security teams log 54% of successful attacks and alert on just 14%. The rest move through your environment unseen.

AI infrastructure startup Tensordyne has taped out its first commercial accelerator, with fabrication on TSMC’s 3nm process already underway.

Developed in collaboration with Juniper Networks and Broadcom, Tensordyne’s systems promise higher throughput and lower power consumption than GPUs. It claims to achieve this using an unorthodox approach to mathematics that uses logarithms – which you might recall from high school arithmetic – to make matrix multiplication heavy AI workloads less computationally intensive to run.

In conventional computing, addition is cheap, and multiplication is expensive. Logarithms flip this on its head. Using logs, multiplication essentially becomes an addition problem. a*b becomes log(a) + log(b). 

The trick is converting those values to logs and back again efficiently. There are a couple of ways of dealing with this. One of the easier options would have been to use a lookup table (LUT). However, Tensordyne cofounder Gilles Backhus tells El Reg that relying on LUTs would have been too large to be practical.

Instead, the company uses a heuristic, specifically the Mitchell approximation, to estimate log and antilog for each value. This is still an approximation and on its own introduces too much error to be tenable. To overcome this, Backhus tells us Tensordyne has implemented a section-wise correction mechanism in hardware that delivers accuracy equivalent to that of FP16. However, it’s worth noting that Napier will also support FP8 and 4-bit block floating data types.

In effect, Tensordyne claims to have built a chip in which the multiply accumulate (MAC) unit works without actually doing multiplication in the conventional sense. The result is a chip that delivers power efficiency significantly greater than what you’d see on modern GPUs. Or at least that’s the claim.

Tensordyne says its rack systems will spit out up to 17x more tokens per watt and achieve 13x higher throughput than Nvidia’s Blackwell systems.

Dissecting Napier

Tensordyne’s first commercial chip, Napier, boasts many of the same specs you’d have seen from a high-end GPU just a couple of years ago. 

The accelerator boasts a 300-watt nominal TDP, 144 GB of HBM3e spread across four stacks, 4.7 TB/s of memory bandwidth, and up to 2.1 petaFLOPS of dense FP8 performance. This makes it roughly comparable to Nvidia’s H200 accelerators announced in 2023, while using nearly 60 percent less power.

Having said that, max achieved FLOPS often fall far short of peak FLOPS, so take that comparison with a grain of salt. We won’t know how Napier actually compares to Nvidia or AMD’s latest generation of GPUs until it arrives next year.

Backhus tells us that Tensordyne is leaning heavily on the scalability of its accelerators rather than individual performance. Each chip features roughly a terabyte of interconnect bandwidth, allowing for rack-scale deployments of up to 72 accelerators per pod.

The TDN72

Tensordyne’s system, codenamed the TDN72, consists of eight air-cooled compute blades, each with a single 10-core Intel Xeon-D host CPU and nine Napier accelerators.

These chips are interconnected by a high-speed interconnect fabric topology reminiscent of the one used by Nvidia’s GB200 NVL72 rack systems.

Each chip connects to six proprietary fabric switch blades developed by Tensordyne’s networking partner Juniper, located at the back of the system, in an all-to-all fabric.

Despite some similarities to Nvidia’s NVL72 racks, Tensordyne’s TDN72 will be much smaller and won’t require liquid cooling, which should make it easier to deploy in older brownfield datacenters.

According to Backhus, up to four 30 kW TDN72 systems can be packed into an – admittedly large – 52U rack. That works out to 608 petaFLOPS in a 120 kW footprint, or about 1.68x more dense FP8 compute per rack than Nvidia’s GB200 NVL72. That doesn’t take into consideration the fact that Nvidia’s kit supports NVFP4 acceleration while Napier is limited to FP4 weights. But again, don’t read too much into that comparison. Peak FLOPS are not representative of real-world performance.

Tensordyne’s TDN72 launches next year, and it’ll be competing against Nvidia’s next-gen Vera Rubin and Vera Rubin Ultra systems, which will no doubt be a stiffer fight, especially when software compatibility is taken into consideration.

Software promises

Since building its first prototype silicon a few years ago, the company has gone to great lengths to keep its software platform as simple and easy for customers to deploy, as possible.

For example, the prototype lacked the error correction found in its Napier chips, and would have required users to use quantization-aware training to adapt their models to run accurately on the hardware – not exactly feasible for those looking to run trillion-parameter models.

The software has also matured such that the hardware’s compiler can convert existing models to run directly on its latest hardware, an approach we’ve seen from other chip startups like Tenstorrent.

For inference, Tensordyne has developed its own proprietary serving platform, as well as a runtime environment that Backhus says will allow customers to use their preferred inference servers, such as vLLM. PyTorch support is under development.

Before the chip has even shipped, the company is making some bold performance claims. Backhus expects the chips to deliver upwards of 1,000 tokens a second, and that’s without relying on multi-token prediction or other forms of speculative decoding to boost token generation.

Tensordyne’s platform has certainly attracted the attention of neocloud providers like Cirrascale and BlueSky Compute, both of which have expressed interest in deploying the company’s hardware when available.

But, as we’ve seen with AMD and others, software can make or break a chipmaker. With Napier slated for release in Q2 or Q3 of 2027, Tensordyne won’t have long to get things right. ®
