nja··on HSLuv, a developer friendly perceptual color space
The amount of detail in that video is amazing. I noticed it can partially see through chain link gates -- neat!
nja··on The Unfinished History of U.S. Freeway Revolts
I've been wishing for years that this would become available on Kindle. My commute wouldn't allow me to easily lug around such a tome, so I have yet to read it despite its obvious quality. I don't understand why a book publisher would hold out on an ebook version yet have an audiobook available...
nja··on Reset C by GE Light Bulbs [video]
I live in a 300sf studio in a tenement building built in 1917. There's a single overhead glass dome fixture for each room, but with 10ft ceilings they don't shed much light at all. I've added several hue lamps around aimed at the walls so there's plenty of light (I've also added some under-counter ikea halogen lights on a tp-link smart plug). If I had added these bulbs as regular bulbs, I would have to go around turning on/off each bulb every time I wanted the lights on/off. Instead, I can say one command to my google home (picture: walking into the apartment with hands full of groceries -- "ok google lights on" - done) or tap a button on my phone. I've also set up a cron script on a spare raspberry pi to change the color temperature when the sun sets (like flux but for the apartment lights), which helps with sleep cycle and eye strain. By this point, all but one of the dim overhead lights has burned out (I'm responsible for changing bulbs per my lease, but also since I'm living in a small apartment I don't have room for a 10ft ladder, so it's always a hassle to replace them) and I just don't use the wall switches at all.

Is this a major life improvement? Nah, not really. But having lived here for almost a decade, I can say that I like having a reasonable level of light, and the convenience that comes with the smart lights makes that less of a pain. Not like my lease would let me put in more outlets or light switches (the whole apartment is on a single 15A slow-blow fuse circuit).

But thanks for the _order_ to stop buying smart bulbs. Not like anyone has slightly different use cases for these things than the "_horrible_" replace-a-light-already-on-a-switch case that you demonize.

nja··on An underground cathedral protecting Tokyo from floods
wow, those pictures bring to mind the film depiction of the mines of moria in terms of scale and regularity
nja··on Productivity in 2017: analyzing 225 million hours of work time
I used to get something like this, except I described it more like a "burning" behind my eyes. My optometrist recommended reading glasses for computer use. During the day, I wear glasses for nearsightedness, and it turns out that using those while working on a computer was causing a lot of eye strain. I found that reading glasses are actually pretty great -- they force your eyes to focus at a very close range, letting your eyes relax. Since I started wearing them, the burning has gone away. Perhaps you could try something similar.
nja··on Things to know about sleep as the clocks go back
There's a lot of talk in New England about switching to Atlantic Time, which would effectively give us "permanent DST".
nja··on Show HN: Gutenberg – A static site engine as a single executable
Salesforce actually licensed the Einstein name from his estate for their new AI push[1], so it would seem that you can...

nja··on Ask HN: What's the next big advance in AI you're looking forward to most?
fyi that link redirects to pg's homepage for me, since it's erroneously picking up the `);` (auto-linking is hard!) Here's the link, for those who are lazy like me: http://www.paulgraham.com/schlep.html
nja··on New York Subway X-Ray Area Maps
Anyone aware of similar maps for Boston's T system? (as the oldest subway system in America, its stations have many quirks)
nja··on Open Letter to a Car-Addicted City (2014)
not saying the parent poster's solution would 100% work, but as an anecdote:

I live in Boston. It snows here and I do often buy more than one bag of groceries at a time. Fortunately, I just walk two blocks down the street and go into one of the two grocery stores that are right there.

Compare where I grew up in southern NH: it snows there, too, but the nearest grocery store was a 20 minute drive, so of course I would drive there. Rural NH is not a city, though.

nja··on Mapping Greater Boston's Neighborhoods
If you're interested in seeing the results from the 2012 survey: http://bostonography.com/2012/crowdsourced-neighborhood-boun... and http://bostonography.com/2013/neighborhoods-as-seen-by-the-p...

nja··on Leading Architects Defend Hated Buildings
Nobody defending the brutalist city hall building in Boston, I see...

> I somehow think that if you could populate the Plaza with more gardens, and make it feel more part of everyday life — which they’ve tried to do with farmers’ markets and using the basin for ice skating — then it wouldn’t feel so hostile.

Seems eerily familiar to the sentiment surrounding the plaza by the city hall in Boston.

nja··on Better Code Navigation on GitHub
We use GitHub Enterprise for our git hosting, code review, and issue tracking, but OpenGrok[1] for code perusal. It's indispensable, though this looks like it could be a useful intermediary.

nja··on We built a Bitcoin Keurig coffee maker this weekend
FWIW, they won most innovative at the hackathon for this. Great job!
nja··on Computer-driven cars will convulse the automotive industry
Someone recently mentioned horses as a good analogy. Cars replaced horses; now horses are mostly not allowed on roads, and most people do not own horses. However, horse enthusiasts are still able to own horses and ride them, albeit in certain areas. As someone who enjoys driving, I can definitely see this same sort of thing happening with cars. Fortunately, it gives me hope that manually-driven cars won't become completely extinct.
nja··on Google Wallet Users Can Sign Up Now for Physical Cards
Sounds interesting. When I got an NFC-enabled phone, I was excited to use Google Wallet, until I found out that Verizon blocks it. At least with a physical card, I don't have to deal with Verizon!
nja··on VLC 2.1.0
So are all the 2.X releases going to be named after Discworld characters? Twoflower and now Rincewind...
nja··on My Daughter’s Homework Is Killing Me
I spent a minute looking at that too. I think the author inserted the [sic] because:

    "quotes [...] with 1–2 sentence analyses of its [sic] significance"
If the "its" is referring to the quotes, it should be "their significance".

nja··on How To Take Exceptional Notes and Be Productive with Paper
I dunno, I recently bought a fountain pen and have been using it everywhere. It's just nicer and easier to write with. Short notes, long notes, journals, books, whatever.
nja··on Unix Commands I Wish I’d Discovered Years Earlier
Wow. Thanks for this. I always cursed myself for forgetting to pushd, and now it turns out I didn't need to!
nja··on Unix Commands I Wish I’d Discovered Years Earlier
Actually, after hitting C-R <keyword>, you can keep pressing C-R to search backwards through the history. Or C-S to search forwards. More info: (bash uses emacs editing mode by default) http://www.gnu.org/software/emacs/manual/html_node/emacs/Bas...
nja··on How a Car Engine Works
If you find this sort of thing interesting, it might be fun to mess around with designing your own engine in Automation[1]. I've always been interested in cars, but playing around in this (currently in-development) simulation/game gave me a bunch of new insight into various engine parameters.

nja··on Psd.rb
I think that comment itself was posted on HN or somewhere -- I know I've seen it before.
nja··on Psd.rb
Does anyone know of a similar tool for Python?

Not trying to start a Ruby/Python fight or anything; Python just happens to be my preferred language.

Then you're on the security camera footage. How would you avoid that?

What about the security cameras at the store?
nja··on The Year of Dressing Formally (2008)
At a former job of mine, we used to have "Formal Friday." Soon enough, some started to attend "Flannel Friday" instead and it became quite the office-dividing phenomenon. Regardless, it can be quite fun and effective to have informally-defined clothing days. Gives people a nice chance too try out new pieces and styles.
