I don't know how it works in your country, but in RU you only tap to get in, not to get out. There are no barriers to get out. 1. The card stores not only your ticket/cash data, but also your trips 2. You live far from the metro,

Another example: PCIe ASPM exit latency. Fast LAN speed (because the card does not have time to go into sleep) but low internet speed (manages to enter ASPM if the host is at least 3ms away) https://lore.kernel.org/intel-wir

Yeah, somehow nobody invented HCI for Wi-Fi chips. USB has it, Bluetooth has it, but not Wi-Fi.

There's only 1 (one) all-open chip I know of: ath9k ar9271 802.11n 2.4 GHz from 2011. Atheros (now Qualcomm) released its firmware source: https://github.com/qca/open-ath9k-htc-firmware I have many, many these don

They probe all audio devices, including microphones, which probably temporarily switches Bluetooth devices into HPF mode due to how Bluetooth duplex audio works. I'd argue it's "silent" though: aliexpress wakes up my aud

Go to Klipper → Configure Clipboard → Shortcuts And set shortcut for "Next History Item" and "Previous History Item". Believe me, it would be much better. Configure WIN+A and WIN+S for example.

It's not the same thing, it's much better, because you can have a shortcut for "clipboard backwards" and "clipboard forwards", which changes clipboard content based on the history of it. In other words, if you

USB-only is a cost cutting measure. Canon CAPT printers have so low amount of RAM that the page is streamed over USB. There's not enough RAM (1-2 MB) to accept the full compressed page at once for complex pages. Network/Wi-Fi pr

Printers of the 80s and early 90s were more performant PCs than the typical PC which printed on it. Because you can't process full color 600 DPI page on the 90s PC with 8-16 MB of RAM, but the printer needs to do that.

by ValdikSS 2mo ago
Once and for all solution is to run a dedicated print server for outdated printers, which implement AirPrint/Mopria and convert the incoming data into printer's native language. This way it withstands all the PC/smartphone OS

So far we haven't found any card with binned RAM. All memory is working and doesn't flip bits.

If it weren't mmaped files, I would use strace/gdb, or even fuse proxy file system. But these are mmaped, I don't know any easy debugging or monitoring solution besides writing kprobes/systemtap hooks. How would you debu
