While getting a new (Samsung) tablet, I went ahead and sprung for a crummy laptop at a decent price - for basic web browsing, document production, portable access to things, etc. Comes with Windows 10 - I'm going to try to put Linux on and dual-boot, but I'm trying to remember rumors about how Windows 10 and new boot thingies made that tricky or something, or at least that there's a wrinkle or something that you have to make sure to get right.


This seems to me to be right: https://www.seriouseats.com/2018/09/what-is-the-instant-pot-good-for.html I don't have one but people keep talking about it, and it always seemed to me to be "only" a user friendly electric pressure cooker. Which, to be fair, is a nice thing to have, but hardly revolutionary and should be compared to other, similar offerings. Perhaps it has a better price point or something, but it's not so special.

What the title is a reference to is perhaps slightly unfair - I was doing this mostly while waiting for some results. I wrote a small R package early last year for fast generation of inverse Wishart distributed random variables and a few related functions because it came up and there was a void. I saw that it's possible to define the so-called pseudo-Wishart and its pseudo-inverse (called the generalized inverse Wishart), and it made sense for that to be part of my package, so I put them in. (for those wondering: suppose you have n independent observations of a p-dimensional normal distribution (arranged, say, as X, an n by p matrix) with covariance matrix Sigma - then the p by p scatter matrix X'X is what you're looking at, the pseudo-Wishart is when you don't have enough observations to guarantee this is positive definite). I should also probably include the case where Sigma is not positive definite and the case of non-independent sampling (indeed, also possibly singular) for completeness. But that gets annoying.

I have a mild concern at the back of my mind - I'm on a federal grant this upcoming semester. Hmm.

While trying to poke at the dead tablet, I finally got my phone-to-computer hookup working. I probably should have a newer phone, it was outdated when I got it, but I'm not really a person who either needs or affords the latest tech. However, to my chagrin, I found out when I tried to access my banking app that it no longer supports my version of Android. I also finally got Tor installed and working on my computer, not that I intend to use it for anything, I just thought it was interesting. Tor, like blockchain/cryptocurrency, is mostly silly, though unlike blockchain, it might actually  have some use.

Right now the pod-cast "You're Wrong About..." is popular in this household. Highly recommended. The first one we listened to was the Urban Legends Spectacular, which I think gives a good feel for their style if you also want a good entry point. Other pod-casts we regularly listen to together: Rational Security, FiveThirtyEight Politics, Mass for Shut-Ins, Stay Tuned with Preet. These are generally far more conservative than we are but quite good and informative. One I might recommend beyond this is the Sean's Russia Blog Pod-cast, which is mostly interviews with academics who are somehow connected with the area around Russia about their work - usually Russian history, sometimes Russian current events. As you might expect, much of it is Soviet history and politics. And then there are more partisan or niche pod-casts I don't really recommend unless you have an interest in them.

Trying out Nextcloud as an alternative to Dropbox.

So tumblr has essentially destroyed itself and people are looking for alternatives. Frankly, I think mastodon fits the use case of many of these folks' communities but there are hurdles to that. It looks like the people I know are moving toward Pillow Fort. Hope it works out for them.

Uh, I think that's about it for today.

Pressure cookers by TheophileEscargot (2.00 / 0) #1 Sun Dec 30, 2018 at 03:02:08 AM EST
Last time we discussed them it seemed that in the US they were regarded as dangerously likely to explode. Wonder if these these are actually any safer or just perceived that way. I guess if they're electronic they could turn off the heat if the pressure gets too high, even if the valve is blocked.

I hear they're fairly user friendly by gzt (4.00 / 1) #2 Sun Dec 30, 2018 at 10:16:09 AM EST
So perhaps it's solving that problem

Anecdotally... by ana (4.00 / 1) #3 Sun Dec 30, 2018 at 10:55:31 AM EST
We lived in Colorado at a mile above sea level, give or take. So a pressure cooker was a good thing since the boiling point of water is rather lower up there than it is down by the sea.

A friend of my parents was badly scalded in a gasket failure on her pressure cooker. I think she recovered.

Once when I was a kid my mom was cooking something for dinner. Came time to vent the pressure cooker, and so she had it in the sink and ran water on the lid to cool it. The gasket failed and let out a yelp like a dozen puppies being murdered. Nobody was hurt in that incident, but mom was duly warned about the dangers of the gadget she depended on.

I actually have one on a basement shelf that Herself bought for sterilizing canning jars, for making jelly and pickles and the like. Perhaps she'll want it to stay there when she moves in again.

Wait. How would you know by wiredog (2.00 / 0) #8 Wed Jan 02, 2019 at 07:39:40 AM EST
what a dozen puppies being murdered sounds like?

Modern ones are pretty legit by coryking (4.00 / 1) #4 Mon Dec 31, 2018 at 04:59:25 PM EST
It is the old school ones that are unsafe.

..That being said, I haven't used mine in a very long time.  Slow cooker & rice maker stole away most of what I'd use it for.

rice maker by gzt (2.00 / 0) #5 Mon Dec 31, 2018 at 10:27:24 PM EST
a friend of mine with a pressure cooker said that it can do brown rice in like 15 minutes.

It can by lm (2.00 / 0) #6 Tue Jan 01, 2019 at 02:44:01 PM EST
We picked up an electronic pressure cooker years ago. Used the fuck out of it until one of my daughters lost an important piece.

Dry beans from start to finish in 15 minutes too.

And pretty much any crock pot recipe in 10 minutes give or take.

I think it's mostly a user thing by lm (2.00 / 0) #7 Tue Jan 01, 2019 at 02:45:46 PM EST
The old ones would get left on stovetops with the burners going, forgotten about, and then explode like bombs.

The electronic ones would require a pretty big software glitch or rather interesting hardware failure to do the same thing - if they even can.
