Remember @janmarjanovic 's discovery about second, hidden PCIe HIP in the Microsoft Stratix V GS (j-marjanovic.io/stratix-v-ac…)? Well, guess what, @gatecatte figured out how to enable it!

If you are interested in "fun" networking quirks, @blueCmd just wrote a blog post about a pretty interesting one discovered while trying to test a network topology with VLANs. blog.mainframe.dev/2021/08/t…

Samsung S10 phone running a Soviet clone of IBM operating system #VM/SP r4 and calculating the N-Queens problem in #REXX. Because what else would I do at the #beach in the dog days of summer??

Det förblir märkligt - om jag uttrycker mig mycket försiktigt - att Sverige fortfarande inte har en fungerande cyberskyddsmymdighet. Behovet har varit tydligt sedan år tillbaka.

We've never been deep stealth, but it is nonetheless really fun to get some more specific details as to what we're building -- with much more to come!

It looks like @barefootnetwork is going to open up more info about the Tofino TNA architecture previously only available under NDA. Very important for users who want to open source their P4 code including p4runtime control plane code! Good move @intel ! github.com/barefootnetworks/…

Landmark decision today from SCOTUS on Oracle v. Google, and a huge win for software innovation. There are lots of good threads out there this morning; this one is a favorite 👇 – at Piedmont, CA

After a ton of cleanup and documentation, this is now fully open source: The BLE radio: github.com/newhouseb/onebitb… The building blocks: github.com/newhouseb/alldigi… Since I basically learned RF from scratch to build this, I spent a lot of time documenting, which I'll preview below...
I just built a Bluetooth receiver using nothing but a Xilinx FPGA and an antenna. No ADC, no filters, no mixers, no AGC, not even an amplifier. Just straight RF into a SERDES port at 5Ghz. Here it is discovering nearby devices ("I LOVE MINDY" is the nearby Particle Argon).

The Go programming language is now available for z/OS. Can't wait to re-deploy my Go code inside z/OS. And of course, write a VSAM access package for Go, too. ibm.com/products/open-enterp…

One thing that has always annoyed me about SERV is that it uses so much resources. Today I decided to do something about that and removed six FFs. Now I just need to do something about the 185 remaining ones github.com/olofk/serv
