always a good sign when you call an oscilloscope manufacturer to sanity-check a product choice, then explain your problem space and when you mention LPDDR3 they say "what's that?"

i wonder if having an mp3 player ready to go in every room in my apartment will cause me to develop strange user habits and behaviours

@jacqueline have one genre of music on each player and then watch yourself associating each room with specific music? 😹

Rendere 55 Minuten Video in HD, "H.265 Studio" mit Davinci Resolve auf einem Apple mini M2 pro.

Lies die Daten von einer externen USB-C QVO 4 TB und schreibe auf die interne NVME.

200 fps
32 Watt
73% GPU

und so ca. 60 MB/s lesend, 15 MB/s schreibend.

2.85 GB Dateigröße.

"Das ist schnell genug"

Die NVidia 4070 Windows-Kiste habe ich nicht probiert, aber weiß, daß die bei 85W idle ist und bei Horizon: Forbidden West bei 400W peaked.

der 7800X3D ist (zumindest in Real-World-Spiele-Workloads, nicht Rendering) auch der klare Performance/Watt Leader.

@isotopp @Lalufu Da ich annehme -- dass das normalerweise deine Computerspielkiste ist, ist das eine sehr sehr gute Wahl :)

Wobei wir neulich auch eine Prod-Workload gehabt haben (ueber die ich leider noch nicht so richtig sprechen darf), die auf einer CPU aus der gleichen Serie (mit genug Cache) ploetzlich 12x (!!!) schneller wurde.

Letztens festgestellt dass mein Internet-Tarif für Neukund*innen inzwischen 65 € monatlich kostet statt der 40, die ich bezahle.

Ich kann nie wieder umziehen.

@wonka @toni @scy Die kam bereits, ich muss mehr bezahlen. Da gibts auch gerade richtig Stress wegen für Vodafone.

Sind wohl aber nicht alle Tarife betroffen / manche wurden vergessen.

If you're building a CLI tool that can churn on large amounts of data for hours and you don't implement any kind of progress output, we won't become friends.

(And no, it refuses to work with stdin, else I would've just used pv and be done.)

we may have found a really bizarre bug in the Intel I219-V ethernet controller

@whitequark only one?

does it involve offloading features or jumbo frames? both are severely broken.

holy shit, i... solved bufferbloat (in one direction) in my userspace Python Linux network interface card driver in Glasgow?

i'm sending 200 Mbps of spam to Wanda's laptop right now (most of which doesn't fit into the 100M link) and pings never go above 25ms

also she gets acceptable realtime performance (ssh, etc)

I: g.applet.interface.ethernet_rgmii: usb->os pps= 16 Mbps= 0.03
I: g.applet.interface.ethernet_rgmii: os->usb pps=17862 Mbps=215.87

@niconiconi @gsuberland @DM_Ronin I can do CT inspection on small boards (small enough to fit in all rotations into the chamber), but that's not often the case.

Did work for a small sensor PCB, though.

✔ make one part of a RGMII MAC work by adding LUT4s to a design that do nothing
✔ make the other part of the RGMII MAC work by rearranging some of the wires to connect the exact same pins but with different wires adjacent to each other

@whitequark and some truely atrocious buffer bloat :)

where is Dave Taht when we need him? 😹

manawyrm,
@manawyrm@chaos.social avatar

@whitequark but 235ms under load according to speedtest.net.

I'm guessing that's already noticable when just surfing the web via the gadget...

manawyrm,
@manawyrm@chaos.social avatar

@whitequark I didn't actually want to say: "you'll need to fix that", I don't think anyone's going to try and build a router with a glasgow 😹

just mostly a fun real-world example for buffer handling.

manawyrm,
@manawyrm@chaos.social avatar

@whitequark @foone synchronized catgirls :3

manawyrm,
@manawyrm@chaos.social avatar

@whitequark yeah, that's classic buffer bloat behaviour and one of the biggest problems when building routers :)

when their cpu is exhausted, things also start to suck.
it's the typical "uploading a file kills my video call", which doesn't actually have to be a problem (these days).

manawyrm,
@manawyrm@chaos.social avatar

@whitequark i don't think it's a problem which you should try to solve -- even the purpose-built USB NICs suck at this -- which is (one of the many reasons) why USB NICs suck so much in general :D
