Long-time Slashdot theodp says this "provocative" blog post by former Google engineer Avery Pennarun — now the CEO/founder of Tailscale — is "a call to take back the Internet from its centralized rent-collecting cloud computing gatekeepers." Pennarun writes: I read a post recently where someone bragged about using Kubernetes to scale all the way up to 500,000 page views per month. But that's 0.2 requests per second. I could serve that from my phone, on battery power, and it would spend most of its time asleep. In modern computing, we tolerate long builds, and then Docker builds, and uploading to container stores, and multi-minute deploy times before the program runs, and even longer times before the log output gets uploaded to somewhere you can see it, all because we've been tricked into this idea that everything has to scale. People get excited about deploying to the latest upstart container hosting service because it only takes tens of seconds to roll out, instead of minutes. But on my slow computer in the 1990s, I could run a perl or python program that started in milliseconds and served way more than 0.2 requests per second, and printed logs to stderr right away so I could edit-run-debug over and over again, multiple times per minute. How did we get here? We got here because sometimes, someone really does need to write a program that has to scale to thousands or millions of backends, so it needs all that stuff. And wishful thinking makes people imagine even the lowliest dashboard could be that popular one day. The truth is, most things don't scale, and never need to. We made Tailscale for those things, so you can spend your time scaling the things that really need it. The long tail of jobs that are 90% of what every developer spends their time on. Even developers at companies that make stuff that scales to billions of users, spend most of their time on stuff that doesn't, like dashboards and meme generators. As an industry, we've spent all our time making the hard things possible, and none of our time making the easy things easy. Programmers are all stuck in the mud. Just listen to any professional developer, and ask what percentage of their time is spent actually solving the problem they set out to work on, and how much is spent on junky overhead. Tailscale offers a "zero-config" mesh VPN — built on top of WireGuard — for a secure network that's software-defined (and infrastructure-agnostic). "The problem is developers keep scaling things they don't need to scale," Pennarun writes, "and their lives suck as a result...." "The tech industry has evolved into an absolute mess..." Pennarun adds at one point. "Our tower of complexity is now so tall that we seriously consider slathering LLMs on top to write the incomprehensible code in the incomprehensible frameworks so we don't have to." Their conclusion? "Modern software development is mostly junky overhead."

One of the more subtle trends at this year's Computex was that the majority of high-end motherboards now come equipped with a 5GbE network controller. At present, this might be considered a limited benefit as 5GbE and 10GbE switches and routers are still pretty expensive. But Realtek is planning on tackling the issue from both ends, as the company is preparing a hardware platform for sub-$100 5GbE switches. 

Realtek’s quad-port 5GbE switch platform consists of five key chips: one RTL9303 switch system-on-chip, and four RTL8251B 5GbE physical interfaces (PHYs). The chips are accompanied by various other components, such as power management ICs, but in general it relies solely on in-house developed components, which is why it can be made so cheap. 

RealTek's platform is meant for home and small offices, which is reflected in the switch's feature set. This is a simple, unmanaged switch with a handful of ports, making it ideal for linking up a few systems, while enterprise users will likely find it a bit too basic.

Segmenting the market like this is ultimately critical for bringing down the price of hardware. The bulk of 5GbE/10GbE switches on the market today are more enterprise-focused managed switches, which carry more features and a price premium to match. So developing a stripped-down platform for cheaper consumer switches is a huge development that should finally make it economical for consumers to adopt faster networking hardware, similar to 2.5GbE a few years ago.

At present, 2.5GbE switches are running at around $20/port, so RealTek's sub-$100 target for a 4-port switch aims to bring 5GbE in at just a slightly higher price tag of $25/port. Or, compared to the handful of unmanaged 10GbE switches on the market, which average $60/port, this will be less than half the price (though at half the bandwidth).

The proliferation of cheap 5GbE network switches will also mark a notable inflection point in Ethernet hardware design, as it's the fastest standard that is rated to work the ubiquitous Cat 5e cable. The NBASE-T standard was penned almost a decade ago in order to cover the missing-middle between 1GbE and 10GbE, while getting more bandwidth out of existing, widely-deployed Cat 5e cabling. So with the release of consumer 5GbE gear, the standard's goals are finally coming to fruition – though it does mean we're finally reaching the end of the road for the oldest network cabling still widely in use.

For now, Realtek is only talking about one customer offering a sub-$100 5GbE switch this September, but something tells me that other partners of the company will come up with similar devices soon enough. As a result of the competition, prices could get even lower, which is always good for buyers.

These benefits should also funnel into Wi-Fi 7 routers, to a limited extent. Wired backhaul speeds need to keep pace with ever-faster Wi-Fi standards in order to keep those newer radios fed, so it's not a coincidence that cheaper 5GbE is finally coming right as Wi-Fi 7 is taking off.

Overall, the company's 5GbE switch platform is part of a larger ecosystem of 5GbE hardware that Realtek was showing off at Computex. In addition to RTL8251B 5GbE PHYs and RTL9303 switch SoC, the company is also preparing their RTL8126 PCIe 3.1 network controller, and RTL8157 NIC for USB dongles.
