Valve finally announced the price of the Steam Machine, and like a lot of new gadgets these days, it's not cheap: It starts at $1,049 for a 512GB model, and a 2TB model costs $300 more. Configurations with a bundled Steam Controller cost an extra $79 each. Despite Valve offering a console alternative with the […]

My first day with the Steam Machine was a mess. Instead of enjoying a worry-free game console, I spent hours troubleshooting what felt like a finicky PC. That's because the Steam Machine is a PC, with a very important twist. Since the Magnavox Odyssey came out in 1972, game consoles have been built with the […]

After months of waiting, Valve has finally announced that the Steam Machine, its new living room-friendly PC, will start at $1,049 and go on sale beginning June 29th. You can now register your interest to buy a Steam Machine as part of a reservation system. To offer a fair playing field for people who want […]

nvidia-peermem "Invalid argument" on Ubuntu — Fix GPUDirect RDMA with DMA-BUF TL;DR: If modprobe nvidia-peermem fails with Invalid argument ( -EINVAL ) on a system using the inbox Ubuntu InfiniBand stack ( rdma-core ), the module is not broken and you do not need it. nvidia-peermem requires an API that only exists in MLNX_OFED. On Hopper/Blackwell GPUs with the NVIDIA open driver, use DMA-BUF instead — it does GPUDirect RDMA natively. The one gotcha: you must enable nvidia-drm modeset=1 . Applies to: Ubuntu 22.04 / 24.04, inbox rdma-core stack, NVIDIA open kernel driver, H100 / H200 / B200, ConnectX-6/7 (or any HCA with ODP support). The symptom $ sudo modprobe nvidia-peermem modprobe: ERROR: could not insert 'nvidia_peermem' : Invalid argument dmesg shows nvidia-peermem loaded but registered nothing, or the load returns -EINVAL . GPUDirect RDMA appears to be unavailable. Why this happens (and why it is not a bug) nvidia-peermem is the legacy path for GPUDirect RDMA. It registers GPU memory with the InfiniBand subsystem through a Mellanox-proprietary kernel API: ib_register_peer_memory_client () That symbol only exists in MLNX_OFED's build of ib_core . It is not in the mainline kernel, and it is not in rdma-core , which is the inbox InfiniBand stack on Ubuntu. If you are on the inbox stack, nvidia-peermem was compiled without that API present, so it can never bind and always returns Invalid argument . No module parameter or config change will fix it, because the thing it needs was never there. Do not install MLNX_OFED just to make nvidia-peermem load. That works, but it is the wrong fix — you would be adding a heavy proprietary stack to revive an obsolete module. There is a native path already in your kernel. The fix: use DMA-BUF On Hopper and newer with the open driver, GPUDirect RDMA works through DMA-BUF , a mainline Linux framework. No external module, no MLNX_OFED. Requirements (check these first) NVIDIA open kernel driver (not the proprietary build) nvidia-drm

The Snapchat maker is spinning off yet another internal unit. Dotmo will be comprised of current Snap staff who are leaving the social media company to focus on AI video development.

Valve has some good news and bad news about Steam Controllers. The good news: if you make a reservation for a Steam Controller, the company will now show you one of three estimates of when you'll be able to actually order your gamepad: by September 2026, by December 2026, or sometime in 2027. The bad […]

Snap's new smart glasses are probably the most impressive bit of face-computer technology we've seen. They're not VR-headset huge; they don't have a big charging puck; thanks to Snap's many years of AR lens development, they're likely to have a lot of features right out of the box. (Yes, they're $2,195, but that may just […]

We'll see how players react.

For over a decade now, Snap has been working on this device. Now the glasses are finally here. So what stands out on first impression?

Snap CEO Evan Spiegel lays out the company’s vision for its augmented-reality smart glasses, arriving later this year.

Snap is finally launching augmented glasses for the public. Specs, which Snap describes as "a wearable computer built into see-through augmented reality glasses," will cost $2,195. You can preorder a pair of Specs now at specs.com with a $200 refundable deposit, and Snap says they're expected to ship "this fall" in the US, UK, and […]

Roblox's vice president of safety product policy, Eliza Jacobs, told NBC News that Roblox is "optimistic" that its new facial age estimation tech will "continue to get better," saying, "Ticking a box to say you're 13 or older, it's not enough anymore." NBC invited a group of kids to try out Roblox's new video selfie […]

Broadcom released Spring Boot 4.1 on June 10, 2026, to deliver gRPC auto-configuration, HTTP-client SSRF mitigation, and upgrades to Kotlin 2.3. It also brings lazy datasource connections, async context propagation for @Async methods, and improved OpenTelemetry support. Uncharacteristically, Broadcom moved the releases twice, first from May 11-22 to June 1-5, then to June 8-12. By Karsten Silz

On June 10th, the German container ship Posen docked in Los Angeles after a two-week voyage from Shanghai. As Valve watcher Brad Lynch notes, it was almost certainly carrying the first mass production shipments of the Steam Frame, Valve's new gaming headset. Import records show that Valve's distribution partner Ceva offloaded nearly 32 metric tons […]

Gaming handhelds are amazing. They make it so much easier to fit all kinds of games into my day. Sadly, they’re less affordable than they’ve ever been — due to an unprecedented, AI-fueled shortage of memory chips, an unforced oil crisis, rampant inflation, fallout from tariffs, and more. But that’s not going to stop you. […]

The delayed Fable reboot is coming to Xbox Series X/S, PS5 and PC on February 23.

In a support page spotted earlier by Windows Central, Valve says it will no longer restock its gift cards once they run out, citing scammers who "continue to have an impact on Steam customers and other unsuspecting individuals." In its post, […]
