Its good to have many tests in your R package, but it can be a pain to debug some failing tests when it happens. {lazytest} for the rescue: only rerun the failing tests, until they pass: #RStats

I feel like tech has gotten smarter, and I've gotten dumber. My Roku Ultra says it does Miracast (on the website) but in my settings I see only Airplay. And my phone (android) does not see it when searching. So does it not do it or am I doing something wrong? #feelingold

Yeah, I won't be playing tennis tonight, despite wonderful weather.
On the plus side, I've managed to retain both lungs, and my throat now only feels like a brillo pad rather than a cheese grater.
Feeling much better thanks 🙂

Falling Threads During Solar Filament Eruptions
Mass drainage is frequently observed in solar filaments. During filament eruptions, falling material most likely flows along magnetic field lines, which may provide important clues for the magnetic structures of filaments. Here we study three filament eruptions exhibiting significant mass draining, often manifested as falling threads at a constant speed ranging between 30--300 km/s. We found that most of the falling material lands onto the hooked segments of flare ribbons, only a small fraction…

It's only Thursday morning and I've already had what's probably the most intense and productive week of writing since the home-stretch of my dissertation almost 15 years ago.
I basically wrote the entire first draft - and not a super drafty draft, at that - of what I'm thinking will be the second chapter in my next book.
I'm feeling great.

TL;DR Amazon's SES in sandbox mode only sends to validated addresses and identities defined in the configuration.

AWS SES Message rejected: Email address is not verified.
I configured one of our Magento 2 stage instances today to use Amazon SES to send emails instead of dumping them into mailhog. But I got the following error: Message rejected: Email address is not …

The Saga of $α$-RuCl$_3$: Parameters, Models, and Phase Diagrams
RuCl$_3$ was likely the first ever deliberately synthesized ruthenium compound, following the discovery of the $_{44}$Ru element in 1844. For a long time it was known as an oxidation catalyst, with its physical properties being discrepant and confusing, until a decade ago when its allotropic form $α$-RuCl$_3$ rose to exceptional prominence. This "re-discovery" of $α$-RuCl$_3$ has not only reshaped the hunt for a material manifestation of the Kitaev spin liquid, but it has opened the floodgate…

Are your internal feelings of direction aligned with compass north and 360° ? My first childhood sense was based on the front of the house I lived in, looking east. When I later learned about north I had to imagine lots of those little "front views" posted like icons in the overall north-based world I could only logically imagine in my hea…

Breaking the Trend: How to Avoid Cherry-Picked Signals
Our empirical results, illustrated in Fig.5, show an impressive fit with the pretty complex theoritical Sharpe formula of a Trend following strategy depending on the parameter of the signal, which was derived by Grebenkov and Serror (2014). That empirical fit convinces us that a mean-reversion process with only one time scale is enough to model, in a pretty precise way, the reality of the trend-following mechanism at the average scale of CTAs and as a consequence, using only one simple EMA, app…

Been playing Pistol Whip again. Such a great game. The Black Magic "hard" level, with Reckless and Hell options is ridiculously hard. Finishing at all is a feat.
Was wondering how the hell the top players managed to score so highly. I was in like 4th place thinking I was playing a practically perfect game.
But it turns out only with 188 hits. The top three, I noticed, has 189 hits! There's a secret dude!?
Found him, flying around in the sky mid level on the right.
Nice. That's me 3rd in the global leaderboard for Black Magic Hard Reckless Hell now then.
Maybe I shouldn't be giving the game away. If someone learns of the secret dude from this post and then beats me into 4th place I'll be miffed.
