The HP M283fdw scanner is one-sided (not "duplex")

HP printer model names have a convention with single letters at the end signifying features.  For the M283fdw, "f" signifies fax, "d" signifies duplex, and "w" stands for wifi, possibly also implying wired network.

Duplex means both sides of the sheet of paper.  For printing.  This is a multi-function all-in-one printer, and it has two scanners: a flatbed, and an ADF, auto document feeder, where one puts sheets on the feeder, and it tries to take them thru one sheet at a time.

An ADF scanner can also be simplex (one-sided) or duplex (both sides).  For example, my favorite ADF scanner, the old Fujitsu S500, is duplex (two-sided).

If an all-in-one printer-scanner is designated "duplex", is there an implication that both the printer *and* the ADF scanner are duplex?

In the case of the HP M283fdw, the printer is duplex, but the ADF scanner is one-sided (simplex).  I remember catching this in a retail store with an HP model a few years ago, and being pleased I'd caught it before buying, but now they've got me.  I forgot, and didn't check carefully enough, and fell for the trick this time.  Well done, HP.

As if to taunt the user, the settings menu "Type of copy" has two options: "1-Sided to 1-Sided", or "1-Sided to 2-Sided".

Why piss off customers with this sort of trick?

the persistent idiocy of "privileged ports" on Unix

TCP and UDP have ports.  These are 16 bit; there are 65535 or so per IP address. These protocols don't care to differentiate between the ports.  Elsewhere, IANA presumes to operate a process to allocate "well-known" ports in the range 1-1023, "registered ports" in the range 1024-49151, and to reserve the remainder, 49152–65535, for "ephemeral" ports.  The caller end has to have a port, which is how replies get back within the virtual connection, and these are conventionally picked from the ephemeral range by the OS's networking stack. The whole idea of ports is ridiculous, because it allows ISPs to arse around presuming to decide which services they will "not allow".  Anything that allows IPSs to do anything other than shift opaque packets will allow ISPs to meddle and break things, and due to the Law of Meddling, if they can, they will.  I am currently working around an issue with Claro, a pretend ISP, blocking port 5060, allocated to SI

google is giving more and more 500 errors

Image
Total state capture and moral bankruptcy are not the only problems facing Google.  They are also giving an increasing rate of 500 Internal Server errors.  This is the sort that means they've messed up, but not in a way that they should have messed up.  On the other hand, they have drawn a lovely picture of a robot falling apart. Today's example is from Google Calendar under calendar.google.com.  I was trying to make an appointment, and now I'm doing this. I remember, in 2018, a friend trying to convince me that 500 Internal Server Errors no longer happened, or if they did it was my fault, and that they hadn't seen any for years, and some other things.  They assured me that they would love to see screenshots of such a rare specimen, which I bored them with for a while.  That friend happens to be a Google employee. Well, there are plenty of others posting about Google Calendar on twitter today, including screenshots of 500 Internal Server errors, so I doubt this one is en

Guernsey Waste in incorrect bag-rejection horror May 6th, 2024

Image
The rubbish collection folk at my new place seem pickier than at other places on Guernsey. Last week, they removed some card packaging that I'd included in the card and paper (plastic) clear bag, and left it on the lane.  This week, they have attached a rejection label entitled "Polite Notice".  Just like modern software-engineered error messages (see attached tag "extremely_general_error_handling"), this does not give a specific reason why the bag was rejected, but instead lists miscellaneous possible "reasons", leaving the victim guessing, or perhaps trying to follow a process of elimination. In this case, some possible reasons, which the label does not claim to be exhaustive ("was most likely because ..."), and of which none apply, are: (i) "did not have the required payment sticker" -- no, I applied to 90 litre sticker; or  (ii) (a) "too heavy" -- no, I estimate it was 3kg, and I easily supported the bag's weight o
