One of the main questions I ask in interviews is basically "we have a data pipeline with goal X and constraints A, B, and C. How would you design it?" Depending on how they do, we'll discuss various tradeoffs, other possible goals/constraints, and so on.
This is based on a real system I designed and have been maintaining for ~5 years, and is also very similar to other systems I've run at previous jobs.
About half the candidates complain that it's not a realistic question.

- all ballots are paper
- there's no such thing as provisional ballots
- postal votes have to arrive by end of voting election night
- on election night, ~all votes are counted by hand, observed by scrutineers employed by the candidates
One issue is that this is maybe somewhat of a simplified account of how places count votes (aec.gov.au/voting/counting/). But I also wonder if it's just one of those things the US could not implement if it tried, due to lack of the relevant kind of "state capacity".

I'm currently partway through job application processes at 80,000 Hours and the UK AI Safety Institute. Does anyone have any opinions about those employers?
As someone who is primarily a software engineer and manager / CTO, but not wedded to being those things, if anyone has any other things they think I should apply for or consider doing, let me know? Working independently, unpaid, is also an option.

HomeAssistant. Wow. How had I not heard of this before this year?
It's allegedly an open source home automation system, but I keep running into ways that it's actually way better than that. You can connect it to just about anything: Sure, air conditioning and lighting and smart locks and all the other home automation stuff. But also fitbit, mattress coolers, various internet data sources; you can use it to set up a custom ChatGPT-powered Google Home replacement (finally!).
And it's all so polished! Like, yes you need to be a level-1 technical person to set it up, and to use the more advanced features, but the flows are so reasonable and reliable. I'm genuinely kinda shocked.

New short AXRP with Zhijing Jin!
New episode of AXRP with Zhijing Jin - this time, a short one (22 min), offering an overview of her work. Blurb below, links in comments.
Do language models understand the causal structure of the world, or do they merely note correlations? And what happens when you build a big AI society out of them? In this brief episode, recorded at the Bay Area Alignment Workshop, I chat with Zhijing Jin about her research on these questions.

RIP Inkscape
I recently installed Inkscape in order to make anSVGs for a puzzle hunt... and managed to crash it in less than 10 seconds just by somewhat rapidly clicking/dragging around to try to start drawing. Some Googling seems to confirm it's pretty unstable now; seems like it's not really usable anymore.
(I ended up just generating the SVG programmatically using Python shapely + matplotlib, which was better for my purposes anyway)

Chapters of Familia Romana that are hard, according to me
For background, most chapters are only trying to do one or two 'things'.
Chapter 8:
- all the declensions of quis/quī, hic, is, and ille dropped on you in a single chapter
- in some sense only one 'thing', but that's around 144 forms you've got to remember (4 pronouns x 3 genders x 2 numbers x 6 cases).
- tbh I just went past this and hoped I'd get used to them rather than having to memorize them
Chapter 12:
- the fourth declension
- datives for possession (e.g. "Marcō ūna soror est")
- comparatives
- third declension adjectives
- datives of commanding and obeying
Anyway I'm up to chapter 13 which is less bad, hopefully the density of hard chapters does not increase.

I'm currently on chapter 27 and I have some aversion to re-reading it to do the exercises, because:
- it's just kind of boring (talk about how agriculture works, Julius demanding a tenant farmer pay some money he owes but relenting, Julius nearly punishing a shepherd for letting a sheep get away but then relenting)
- it's also quite long, longer than previous chapters
- it covers the present tense subjunctive which idk is not that hard I think
I'm currently procrastinating by reading the Cambridge Latin Course. But IDK maybe I should just skip the exercises and move on? Or do what I can without re-reading? The next chapter seems pretty cool...

I think that, a little over four years after leaving the country, I finally have no bank accounts or any other ties in Hong Kong.
(They just abruptly cut off my ability to log in, but it was following a conversation about closing my account, so I assume that's what they've done. A more explicit confirmation would have been preferred, but oh well.)
I take this as a vindication of "no matter how late, still better than never" :)

Misophonia has become a serious problem in my life. There's a person, who is totally great, and who is friends with all my friends and gets invited to everything I'm invited to, that I cannot be around for long periods because when they laugh my brain instantly jumps to an emotion not too far from blind rage.
I don't know what to do about this; it's very intense and basically preventing me from doing most social activities, even things in my own house.

Sorry to hear it, this sounds very inconvenient and also socially very difficult to approach
My misophonia feelings have varied over the years FWIW. Certain mouth sounds bothered me a few years ago, then they didn't stand out again til a few weeks ago. But my thing has always been much milder than the thing you're describing.
Have you tried loop earplugs? I think they say they can help with misophonia, and my friend with more widespread misophonia said they help a bit. Idk if they'd help with someone's laugh though.

I spent the whole weekend building this... Err... "Portable" directional 2m #hamradio antenna with @Jen Blight, and it was pretty great.
(It's portable in the sense that it only weighs about 2lbs, and can be taken apart to fit in a backpack. I hope to make substantially more portable ones in the future).
The elements are made from 0.5" PEX irrigation tubing (think hula hoop material), wrapped in copper-coated fabric and copper tape, with a layer of clear "repair" tape to prevent tarnishing, while preserving the mad wizard staff vibes.
Each tube is connected to itself using Anderson powerpole connectors, so they can be easily unplugged, and twisted into a smaller footprint for travel.
The boom is a fiberglass driveway marker, and the mast is a telescoping fiberglass pole.
I don't yet know how well the antenna performs, and as you might be able to see from the VNA, it needs a little tuning. But my radio didn't emit any smoke when I transmitted using it! And the signal made it clearly to its intended target (who was about 30ft away).

Update: I definitely see a fair chunk of gain! Not enough to communicate with Jen all the way in SF from my back yard, but my field strength meter shows ~40 units when my standard whip antenna only gets ~10. I'm not sure how to interpret this, but if it's roughly proportional to power, I think this implies roughly 6dBd / 8dBi? Also as far as I can tell the front/back ratio is excellent; saw barely any movement in the meter when placed behind the antenna.
I'm pleased with this as a first attempt!

in reply to Satvik • •Satvik
in reply to Ben Weinstein-Raun • •I've asked for more specific feedback, and the complaints often come down to "nothing I've done has been like this" and "most of development is web development." That might be true, but we don't have a website/web app, and we're pretty specific about the work involved in both the job description and the phone interview.
(We have had other feedback that's helpful)
Generally, everyone who's done well on this question and joined has been a strong hire, though we've also hired some people who didn't do well that specific question. So I'm pretty sure it's a good question. I'm just a little amused/dismayed at how many people seem to think "realistic" means "web development."
