I needed to build up our inventory of parts to build our network testing products.
So I discover:
1. The Chinese vendor who makes the motherboards has stopped shipping to the US.
2. The memory I need - pretty basic 16gb DDR 4 and 5 SODIMS - unavailable or more than quadrupled in price.
3. M.2 NVME SSDs - unavailable or much higher prices.
F**k those AI companies especially the one that bought all those memory wafers it can't use just to block its competition…

I have no clue whether this will do anything to anything.
Because I’m testing it. On others. Fishing for idiots…

A study testing four AI chatbots on 2,267 news stories in English and French: ChatGPT credited news outlets 1% of the time, Gemini 6%, Grok 7%, and Claude 16% (Laura Hazard Owen/Nieman Lab)
niemanlab.org/202…

ChatGPT, Claude, Gemini, and Grok are all bad at crediting news outlets, but ChatGPT is the worst (at least in this study)
"ChatGPT, one of the most widely used models, covered distinctive content in 54% of responses but almost never credited the originating newsroom."

Raiders Hit With Blunt Admission Over Colts’ Alec Pierce
The Las Vegas Raiders will have the second-most cap space this offseason, per Over the Cap. As a result, the Silver and Black have several options to strengthen their roster, particularly with a franchise quarterback on the horizon in Fernando Mendoza, whom they are likely to select.One speculation is whether the Raiders should look to pursue a wide receiver as Las Vegas lack a No. 1 and even a No. 2 wideout. Indianapolis Colts‘ Alec Pierce is one player who will be testing the market this of…

Remember that drama laptop? Last night I installed TileOS on it. A very interesting project, with River, Sway, Niri, Qtile etc. available. I opted for Qtile, version 2 (that version is now in testing, 1.3 is production). A quick glance yesterday showed a lot straight up working ootb. And great ricing also. Worth a check ✔️

testing out the connection speed. Looks good max for my Telus Fibre connection.
I toyed with the idea of getting one with a 2.5Gb class WAN port as I believe Telus is offering >1Gb connections now... but I resisted. This was only $80 and is far more feature rich than the telus router and should be just as fast if not faster thanks to better internals than the Telus router.
