I once met a person that never drank water, only soft drinks. It’s not the unhealthiness of this that disturbed me, but the fact they did it without the requisite paperwork.

Unlike those disorganised people I have a formal waiver. I primarily drink steam and crushed glaciers.

  • Something to be wary of when interpreting the datasheet:

    • Act10 = LED blinking when Ethernet packets transmitted/received at 10Mbps.
    • Act100 = …
    • Act1000 = …

    Bad wording on their part. What they really mean is: “LED blinking when Ethernet packets transmitted/received AND the link is currently in a XYZMbps link speed mode”. The mode is negotiated once after you plug a cable in and usually does not change after that, regardless of how much data you try to send.

    Technically each linkspeed/mode is a whole ethernet standard of its own, but we mostly gloss over that and pretend to end users that they’re backwards compatible.

    Thing is, its EOL, per Asus. Does this mean that it won’t be supported on OpenWRT for much longer?

    OpenWRT tends to support devices longer and better than the OEM, but it depends on the popularity of the chipset inside the router.

    Many different routers by different companies are almost identical internally, because they use the same chipset. Eg the RT-AC3100 seems to be a bcm53xx variant, of which OpenWRT supports a few dozen products. Support will probably only be dropped when every single one of those devices goes EOL and several years pass (ie no people left contributing/maintaining it and the builds break somehow).

    Router chipsets can be very long lived. Many new devices use decade old chipset designs. Some chipset families have almost identical chips released every few years with slightly different peripherals, clocks & pinouts; but are supported by the same kernel drivers.

    (This is all much better than the world of mobile phone hardware support. Maybe it’s because of different market pressures? Not to mention you don’t have a monopoly that benefits from keeping the hardware fractured. Imagine if people could make a competitor to Android that works across most devices)

    As far as I understand, wireguard is designed so that it can’t be portscanned. Replies are never sent to packets unless they pass full auth.

    This is both a blessing and a curse. It unfortunately means that if you misconfigure a key then your packets get silently ignored by the other party, no error messages or the likes, it’s as if the other party doesn’t exist.

    EDIT: Yep, as per https://www.wireguard.com/protocol/

    In fact, the server does not even respond at all to an unauthorized client; it is silent and invisible.





  • Bleepingcomputer’s title and article are very misleading, the presentation did NOT reveal a backdoor into an ESP32. It looks like Bleepingcomputer completely misunderstood what was presented (EDIT: and tarlogic isn’t helping with the first sentence on their site).

    Instead the presentation was about using an ESP32 as a tool to attack other devices. Additionally they discovered some undocumented commands that you can send from the ESP32 processor to the ESP32 radio peripheral that let you take control of it and potentially send some extra forms of traffic that could be useful. They did NOT present anything about the ESP32 bluetooth radio being externally attackable.

    Another perspective that might help: imagine you have a cheap bluetooth chipset that is open source and well documented. That would give you more than what the presentation just found. Would Bleepingcomputer then be reporting it’s a backdoor threatening millions of devices?




  • All of the the surface normals are backwards. This means your shoe is inside-out; instead of being a solid shoe in a vacuum it’s a shoe-shaped-hole inside a solid universe.

    By default blender renders all polys as double-sided so you mostly don’t notice (other than some lighting oddities near corners). Turn on backface culling if you want to check if your normals are the right way around or not.

    I often end up with some of my polys backwards because of the way I extrude and join parts of my models. I distinctly remember a bug in Gmax (old free version of 3DSmax) where the mirror tool would create polygons with some special, broken property where their normals would be correct in the editor, but completely wrong when exported :( much time and hassle was lost to that.

    Filthy casual.

    My family has a Chiq U58G7P. Warm boots take about 30 sec and cold boots a few minutes.

    Don’t try and press any buttons on the remote during this time or for a minute or two afterwards. They might work, 15 seconds later, or they might get ignored. Sometimes your button press inputs get re-ordered too.

    Factory resets do work, but then all it can do is broadcast TV. If you let it update and install streaming apps then you will be back to the same problems.

    I suspect that it might be running out of RAM and thrashing some poor innocent MMC as swap, but I can’t find a USB ADB port to properly find out (maybe it has one internally?).
