Razer’s new Pokémon collab is not very effective

Razer’s new Pokémon collaboration is a missed opportunity. The four PC gaming peripherals in this lineup are simply reskinned versions of products that already exist, and which cost $20 to $40 more than their all-black counterparts. You really should be getting more for your money here. For example, the themed BlackWidow V4 X keyboard should include at least one highly detailed custom keycap (switching out Alt for pokéball designs doesn’t cut it). Maybe the Kraken V4 X headset could have includ

Using the Internet without IPv4 connectivity

Using the Internet without IPv4 connectivity A few days ago my ISP broke the IPv4 connectivity from my router after a power cut. Fortunately IPv6 connectivity still worked fine, but only a small fraction of websites were accessible. In this post I'll cover how Linux, WireGuard, and Hetzner came to the rescue - keeping the whole internet usable with only an IPv6 connection. Opinions expressed are solely my own and do not express the views or opinions of my employer. Background One morning I

TPU Deep Dive

I've been working with TPUs a lot recently and it's fun to see how they had such different design philosophies compared to GPUs. The main strongpoint for TPUs is in their scalability. This is achieved through a co-design of both the hardware side (e.g. energy efficiency and modularity) and the software side (e.g. XLA compiler). Background To give a brief tldr on TPUs, it's Google's ASIC that focuses on two factors: extreme matmul throughput + energy efficiency. Their origins go back to Googl

Grokking NAT and packet mangling in Linux

grokking NAT and packet mangling in linux Source: Imgur Imagine a house full of devices connected to your Wi-Fi network. From any device, try finding your public IP by visiting https://www.whatismyip.com/. The IPv4 address field should be the same for all devices. This is the IP provided by your Internet Service Provider (ISP) to your router, which acts as a gateway for your internet. So what's happening here? If the IPv4 address is the same, how is the router able to differentiate between th

Here’s Kia’s new small, affordable electric car: The 2026 EV4 sedan

Kia provided flights from Washington, DC, to Seoul and accommodation so Ars could drive the EV4. Ars does not accept paid editorial content. SEOUL, South Korea—Drive enough electric vehicles from enough different manufacturers and something becomes clear: the Korean automakers know what they're doing. From small cars like the Niro all the way to three-row SUVs, the EVs coming out of Kia (and its sibling Hyundai) are as efficient as anything out there, usually with a distinctive style. It's fair

Kia EV4 Review: Price, Specs, Availability

The 2026 Kia EV4 could be an important vehicle in the ongoing global EV transition. To be sold in 140 markets globally, the EV4 is a carefully calibrated shot at bringing long-range electric power into the high-volume mainstream segment of compact sedans and hatchbacks at an affordable price. US and Asian markets will get an EV4 sedan (the model I spent the day with for this review), now built in Korea. Europeans’ preference for five-doors means only an EV4 hatchback will be available in that r
