Well that was fun. One of my sticks of Corsair Vengeance DDR4 just nuked itself on stream.

Good job I speak BIOS beep. Now limping along on a single stick.

What DDR4 are the non-cool kids buying these days?

(EDIT: I'm running an AMD Ryzen 7 3800X on a Prime X570-P for reference)

(Because the cool kids mostly prefer shiny to good)

derryh,

@garius I'm running Corsair Vengeance LPX with a Ryzen 5 5600G on a MSI B550M PRO-VDH, so close-ish. But anything with less obvious specs I use the Crucial compatibility tool, and it's always worked so far. But you may be better exactly matching the stick you have left if your motherboard can do whatever dual bus thingies are around now.

    What do people think about abusing USB-C connectors?

    I have a project with two boards (a GPS logger) so use a cable to link them. I’m using a nice 5 pin plug. But whatever I use needs making up a cable.

    Unless I use a USB-C. The sockets are cheap and can easily be SMD as part of the board. It is smaller and neater. Cheap leads or various lengths and colours available readily.

    The problem is that it won’t be USB-C so may cause confusion. I think I can ensure it does not cause damage, maybe.

    GPS module in small PCB for ground plane.

    derryh,

    @slothrop @revk yeah, I'd prefer that USB C stays USB C only for that reason, but that ship has sailed for micro USB which is 5 pin and is a trash fire of not-usb already. Would that be viable?

    Pals in : where's a good place for kids to eat completely unadventurous food? Like, chicken nuggets and chips, and nothing clever about it. Eldest is autistic, so the more predictable and less noisy the better.

    derryh,

    @christianp Upstairs at the city restaurant, next to the festival theatre, round the corner from chambers street, has proven successful with a similar sounding teenager, as long as its not a busy time.

    Arrg!
    Never a good start to the day when your slow acting insulin decides it will not be slow, and drops your blood sugar to 2 in ten minutes flat.
    It is a good job I had not gone for my morning walk straight away as I’d be collapsed somewhere in Castle Meadows now.
    All good now, but it will mess up my levels all day I bet.
    Rare, but it has happened a couple of times before. My diabetic clinic did not seem to know of it being a thing. Anyone else had this? Ordinary glargine insulin.

    derryh,

    @revk It's been a long time since I had to do insulin injections for anyone, so I had to check the mechanism, but that sounds like it may be an accidental IV. As in the needle hit a small vein, so some or all of it was no longer subcutaneous, and dissolved immediately. Was there any bruising at the injection site?

    Someone wrote me saying:

    "Next week, I'm going to be giving a talk on scientific reasoning to a group of judges and attorneys for the ⬛ ⬛ ⬛ ⬛ Bar Association. More frequently than ever, judges are being asked to take judicial notice (a process where evidence is admitted to a trial and accepted as fact beyond dispute, without a hearing - I'm well aware of how frightening this must sound to an actual physicist!) of scientific principles. Most of these judges do not come from a scientific or mathematical background, but they are nevertheless trying to learn to competently weigh what is presented before them. If you have a moment, would you be willing to share any thoughts on what judges should look out for when attempting to sift through scientific reasoning?"

    Suggestions, anyone? Is there a good book about this for lawyers or judges? That might be better than trying to convey wisdom in a few words.

    derryh,

    @johncarlosbaez Ben Goldacre's "Bad Science" is probably a good place to start. https://en.m.wikipedia.org/wiki/Bad_Science_(Goldacre_book) including how people lie with statistics, misleading drug trials, etc.

    Today in "The World Is Not Bash" rage: submission auth strings.

    $ echo -ne "\0username\0password" | base64

    Debian, bash, it works:

    $ echo -ne '\0mwl@ratoperatedvehicle.com\0testPW!?' | base64
    AG13bEByYXRvcGVyYXRlZHZlaGljbGUuY29tAHRlc3RQVyE/

    FreeBSD, sh, nope.

    $ echo -n '\0mwl@ratoperatedvehicle.com\0testPW!?' | base64
    XDBtd2xAcmF0b3BlcmF0ZWR2ZWhpY2xlLmNvbVwwdGVzdFBXIT8=

    (yes, the missing -e on the command line is a problem, but even so, the beginning of the string should be the same in base64, right?)

    I need something that works on any Unix, in any shell. It seems there should be a portable way to do this with printf, but it (cough) escapes me.

    I suspect @ed1conf knows the proper way to solve this, however.

    derryh,

    @mwl @ed1conf the first character is interpolated, so no?

    Results on Ubuntu:
    derryh@bear-mini:$ echo -n '\0mwl@ratoperatedvehicle.com\0testPW!?' | base64
    XDBtd2xAcmF0b3BlcmF0ZWR2ZWhpY2xlLmNvbVwwdGVzdFBXIT8=
    derryh@bear-mini:
    $ echo -ne '\0mwl@ratoperatedvehicle.com\0testPW!?' | base64
    AG13bEByYXRvcGVyYXRlZHZlaGljbGUuY29tAHRlc3RQVyE/

    So it does look like the missing e.

    Rubbing eyes I may have just committed myself to rewriting a Haskell program in 6502 assembly.

    derryh,

    @mcc this is the point where I grumble in Old Person about Fortran programmers doing the same.

    I wonder if there were the right answers...

    Shit, just realised, I bet I sounds like an AI answered 🙂

    derryh,

    @revk unless it's a blasted industrial ladder diagram, when the "capacitor" is an NO contact...

    Now I bet that was some serious R&D right there.

    And hopefully not marmite flavoured!

    Update: tastes fine to me!

    derryh,

    @revk @davidga I'd guess that the most likely candid is bitrex, so isopropyl alcohol should do the trick.

    wow the autodesk fusion 360 API docs are interesting. it seems like they're trying to see how much documentation they can write without possibly being useful

    derryh,

    @foone it appears that you may have stepped in some Enterprise Java.

    derryh,

    @resuna @cstross @charliejane I vaguely recall it being hinted in the New Adventures that The Culture were the only people Gallifrey had a formal peace treaty with. So there's probably something to play with there.

    derryh,

    @resuna @cstross @charliejane ah, yes, sorry. My set were destroyed in a flood some years ago, so the stories are blurring together, and I was never very good with names.

    derryh,

    @resuna @cstross @charliejane I remember them as averaging out as "good", but had the entire spectrum of quality, and I was much younger so I don't know how they stand the test of time.

    derryh, to random

    Of course there's a good reason, but it's always a little jarring that a place called Rostov-on-don is in Russia, rather than being a few miles outside Aberdeen trying to attract tourists with the quality of their pehs.
