There are RTL8127 cards with SFP+, e.g. https://www.lekuo.com/product_view.php?id=659

edit: on looking closer, that still seems to be an x4 card.

I think the point he is making is that the industry first went with a 10g single link, and then 40g over 4 links. Then they figured out how to do 25g over a single link, and 100g over 4 links. Those 25g/100g are common for enterprise switches. It might be fairer to say 40g is dead, 10g still has use cases.

Edit to add: If you want an example, these are the NVidia ConnectX nics available from FS.com, the lowest end one is 25g, then 100g, 200g etc.

My experience: I was using synergy to handle a Windows and a Linux machine, and later display-switch, but they started to be flagged as suspicious by our corporate AV. I tried some external KVM but couldn’t find one which was reliable for 4K. I ended up buying a Dell monitor with a built in KVM and have been using that ever since.

It is commonly known as ‘Fair, reasonable, and non-discriminatory (FRAND)’. Some standards organisations will only accept contributions where a patent owner agrees to license them under FRAND terms.

If you want to avoid the initrd loophole then you will want to look into UKI images. These extend the secure boot signature to include the kernel and ramdisk:

jburgess777 — Thu, 18 Dec 2025 15:08:07 +0000

EXO lets you run your own AI cluster at home with everyday devices. We take advantage of Apple's M-series hardware and unified memory to run large language models, building a cluster to enable even more memory.

EXO underwent a full rewrite for v1. For legacy exo, see this repo's history or exo-explore/ex-exo for a snapshot.

One which gets mentioned often is NAND 2 Tetris, which starts with basic logic gates and progresses to produce a simple computer:

Olimex just released a 1 euro game ‘computer’ based around a tiny RISC-V microcontroller. It drives a monochrome VGA display by bit-banging a couple of GPIO lines in software. Obviously the use of a microcontroller is cheating a little, but likely makes the system cheaper than anything which could be built with discrete logic or FPGA.

The repo below has support for building a 32bit RISC-V CPU for de10nano. It also includes information about booting Linux.

https://github.com/litex-hub/linux-on-litex-vexriscv

The CPU will likely have a clock speed around 100Mhz, far slower than the 1.5Ghz 64bit cores on the VisionFive 2 or Pi4. The FPGA might still be useful if you want to customize the CPU or integrate other custom hardware.

They do have something like this, an ESP32 based system for IoT using FreeRTOS.

I am not sure of the exact relationship AWS has with FeeRTOS, but the FAQ says they have ‘taken stewardship’ of the open source project.

When you ran basic code you were effectively root, you could peek or poke any memory address or hardware register.

M5Stack is an AWS partner for a new “AWS IoT EduKit” so I imagine you will be seeing more projects using them in IoT roles. The getting started guide has some examples.

> it’s too expensive.

Can you identify a time when cost was obviously a signifcant factor in a military choice? To me it seems that cost is low in the grand scheme of things.

What I was told is that if you research the patent and aware of its existence then you may be guilty of willful enfringement with treble the normal penalties:

My reading of this is that the ex-employee used the knowledge about EC2 instance credentials being accessible as a path to gain unauthorized access to data. In theory anyone could have exploited this vulnerability even if they had never worked for Amazon. They never say that Amazon employees had privileged credentaials that would give them unauthorized access to customer data.

AWS customers that want to avoid this vulnerability should disable IMDSv1 as per https://aws.amazon.com/blogs/security/defense-in-depth-open-...
