Corroborative V&V for Autonomous Systems

I have a publication in the Agents and Robots for Reliable Engineered Autonomy (AREA) workshop. Corroborative V&V for Autonomous Systems: Integrating Evidence and Discrepancy Analysis for Safety Assurance. It should be open access, but does not appear to be. It's not a super-exciting paper. It takes the observation that, if you are doing assurance of robotic systems you will take a variety of approaches; abstract models, simulated tests, hardware tests... and then have to reconcile the results of these approaches. The paper describes the first stab at a tool for this, but it is a very early prototype.

an assortment of nice things

Despite *gestures* everything, there are still nice things sometimes!

  • Miss H just got made redundant, but on Friday she heard that she'd successfully interviewed for another job at her institution, so the cat's Dreamies are no longer in peril.

  • Another friend just got promoted! Exciting new job title.

  • I have some annual leave this week, and it's going to be amazing.

  • Pictures!
irrepressible

This one's from quite a while ago, but I came across it while I was uploading the others. I did know that flowers could break through pavement, but it's still pretty impressive to see! Tiny little leaves tearing up the tarmac.

Migrants welcome <3

Between Reform somehow, horrifyingly, topping the polls, and my city being smothered in Union Jack flags put up by people who definitely don't have any racist motivations of any kind and who are only purely coincidentally buddies with Tommy Robinson, it's nice to see something I can agree with for once.

gigantic leaf

This was on my parents' road - one of the trees in the allotments was dropping these absolutely colossal leaves all along the pavement. I thought they looked acer-ish, so presumably sycamore, but I've never seen one a quarter of this size before. I told my swimming buddy who volunteers for a tree charity about it, and she suggested it might be a London plane (after saying "I know you said the leaves were absolutely enormous, but I wasn't expecting them to be that big"), which seems plausible on a quick internet search. Just so comically gigantic though.

Not so nice: now I have to go to a double choir rehearsal where a) the conductor has already made it clear that he's not going to follow the precedent of our newly-retired chorus director and finish the second rehearsal early because everyone is tired by then, not that anyone thought for a second that he would, and b) they've cut the break between the two rehearsals down to thirty minutes, which I am not convinced is long enough when we have two and a half hours of rehearsal each side of it...

booklog: second half of September

Paladin's Legacy - Elizabeth Moon ) Not Moon's best work, but I very much enjoyed these; more than I did the first time around.


100. The Gentle Art of Verbal Self-Defense - Suzette Haden Elgin ) I have read enough agony columns to know that people like this do exist, so maybe I'm just lucky enough to have avoided them...


102. The Reign of George III - J Steven Watson ) Still enjoying getting more of this big-picture view of history; it's not my usual preference, but it does make me think differently.


104. Aunty Lee's Chilled Revenge - Ovidia Yu ) I continue to enjoy this series; Aunty Lee is a great detective.


105. The Mountain in the Sea - Ray Nayler ) This seems to have been a polarising book, and the rest of my book group weren't keen, but I thought it was doing some worthwhile things.


108. Deeds of Honor - Elizabeth Moon ) Enjoyable for completists.


109. Connexions - LA Hall ) Just such a charming series, full of genuinely decent people.


110. The Death I Gave Him - Em X Liu ) Cool concept, hated it.


111. Winter's Gifts - Ben Aaronovitch ) Surprisingly charming, considering all the horrific elements.


112. The March North - Graydon Saunders ) I do love this series.

well, how did i get here? (into the blue again, after the money's gone, once in a lifetime)

Much to my amazement, in two hours I turn forty.

Forty. Four zero. 40. 4. 0. I've been telling almost everyone I meet, repeating the facts to strangers and friends and acquaintances, my psychiatrist and my sister and my surrogate aunts. I didn't expect to get here and I find the fact of forty, frankly, jarring. My teeth grit against the absolute insanity of time marching on to this extent—how did I get here?

Some of the people who are reading this potentially have known me since I was 12 and just like me, probably didn't expect me to get here. Mind-boggling as well.

What has changed recently? Not much! To misquote Tolstoy, perhaps happy days are all alike, but each unhappy day is unhappy in its own way. Or maybe it's the opposite, and it's my newfound ability to revel in choice of enjoyable activities with a reliably upbeat mood climate that's truly unlocked this newfound persistence of pleasant presence.

Current psychiatrist has narrowed down my meds and diagnoses to a fine degree, now that she actually believes I'm ill. (Long story but basically she didn't take me seriously until my last attempt. Wait, not a long story.) Who would have guessed that the magic wand would be ~lithium~ and the magic words, bipolar disorder? Doc's not 100% on it yet but I'm pretty convinced.

My intention is to update again tomorrow, but I'll post this now just in case.

(no subject)

The most obvious thing about visiting Mum is how much better she is than last time. You can tell, because instead of lying on the sofa snoozing she kept coming in to stare at me, poke things in my vicinity, remind me of things I agreed to do several hours later in the day, and generally manifest an almost physical aura of PLEASE HANG OUT WITH ME. I did my best, but between work, online social things I already had scheduled in my calendar before this visit was agreed, and my desperate need to spend some time On My Own In The Quiet With A Book, it definitely was not enough. Hopefully my brother will do a better job now he's there.

Anyway, I came home and unpacked, caught up with as many delayed chores as I could bring myself to face, and plunged straight back into ordinary life. The laundry is going to be a couple of weeks to get caught up, I can see already...

Work is not exactly quiet, but mostly the sort of normal where I can hope to catch up with some of the lurking to-do list. I'm still three months behind on the reporting (technically four, but there's only about half-an-hour left on July) but I am feeling much less out of control about everything. At least, unless I think too hard about all of the ongoing items in my 121 action tracker.

I've taken the opportunity to book a couple of days off, at which point I'm hoping to make a start on Christmas planning. I didn't have my usual too-early panic this year because September and October did not have enough time for extra panics, but now it's November and I need to get on with it. The year zooms past, my personal to-do list app accumulates overdue items, and the last international posting date is looming, or will once they announce it.

Poem: "One Big Beautiful BS"

One Big Beautiful BS -
that the sludge of the past could ever be forever burned without consequence

Whose bones are they breaking today
drilling out the marrow of our good earth
emptying out communities to collapse in upon themselves?

perhaps they expect neighbors will be eating neighbors the very next day
all these hoarders so eager to end good governance by the people, for the people

boys in masks waving guns )

Pikmin Icons


Purple Pikmin in an airplain, next to a pikmin with a Carreg Dhu mountain badge. Photo of Grafitti saying Peace Monkey Graffit, Withingon, Manchester, with two pickmin with yellow flowers on their heads down the front. Bunch of Mii's in a mixture of outfits, most with sunglasses, celebrating 100063 steps. View of a road layout showing a red mushroom, and various planters. A blue pikmin an a 3 cupcake holding a cherry

It's remarkably difficult, at least I find it so, to take screenshots of one's iPhone. As a result capturing good images of Pikmin proced challenging.

Seven Deadly Sins of reading

I like the book meme that is going around - I saw it first on [personal profile] naraht's journal, but it seems to be spreading vigorously!

Lust, books I want to read for their cover:
I don't think there's anything at the moment, but I first read Flying Dutch by Tom Holt because of the Josh Kirby cover! Does that count?

Pride, challenging books I've finished:
Speaking purely personally, finishing Arcadia by Iain Pears was a real achievement, although I've no idea why I found it so impossible a read. I've read some books that would probably fall under the popular definition, but I feel like it doesn't count if I was reading them for fun! Maybe St Augustine's City of God; that did feel like a real achievement to get through, it's so enormous.

Gluttony, books I've read more than once:
I mean. Even these days roughly 40% of my reading is re-reading, and growing up it was a lot higher than that! I don't understand people who never re-read. Arthur Ransome's Swallows and Amazons can stand for the vast number.

Sloth, books on my to-read list the longest:
lol where to start. I acquired Consilience by Edward O Wilson in 2009, I think that may be the oldest physically sitting on my to-read shelves.

Greed, books I own multiple editions of:
The Pilgrim's Progress by John Bunyan - I have a Penguin Classics copy, a giant hardback edition with illustrations that looks rather William-Blake-esque, and a tiny pocket hardback that used to live permanently in my rucksack pocket. Oh, and an ebook from Project Gutenberg.

I also have a few dozen audiobooks that duplicate paper or ebooks I already had, and an increasing number of ebooks duplicating paper I already had. Mostly I get one format or the other, but I've picked up quite a few cheap ebooks of favourites where I don't want to get rid of the original, or where I have the whole series in paper and don't want to give away the one or two I have in ebook, etc... I suspect I will gradually prune things down over time.

Notably I'm up to nearly 50 Chalet School ebooks now! But I have spent nearly forty years accumulating my paper set, and it's going to take a while before I'm ready to give them up. Greed indeed.

Oh, and five? six? Bibles? One in German. Plus a couple of New Testaments including one in Greek (I don't even read Greek, it was just so beautiful!).

Wrath, books I despised:
I'm sure there are a ton of better choices that will come to me after I post this, but such is life. I looked through my "Product of its Time" booklog awards and found some promising candidates, but then I remembered Ada Palmer's Too Like the Lightning, which left me with the sort of loathing that feels appropriate for this category. It's not that it was rubbish, because those mostly aren't worth despising really, it's that it was just persistently unpleasant in a gloating kind of way that left me wanting a shower. Ugh.

Envy, books I want to live in:
Relatively few, without a guarantee of being one of the lucky ones! Graydon Saunders' Commonweal books are pretty invested in everyone getting an equal chance, more or less, so that might not be too bad as long as I could be sure of being in the Commonweal and not one of Reems' slaves or something.

Otherwise mostly looking at positive high-tech futures, to be sure of having access to medication and/or medical treatment for my numerous chronic health conditions! Maybe Bujold's Vorkosigan saga? I'd like Beta, I think. But again, I could end up on Jackson's Whole, and that would not end well for me. Maybe a Star Trek novel, that universe is probably as safe as anywhere I can find.
