I use parm rind (Parmigiano Reggiano rind) for a couple things. One is to make a parm broth for Fettuccine Alfredo. Another is when making a pomodoro sauce loaded with aromatics (garlic, red onion, fresh basil, etc).

"Cheese buyers aren't going to eat this embedded label." Are you sure?

From 2010 through 2020, I was working as a mathematician, programmer, analyst, researcher full time on an odd schedule, Tuesday through Saturday. I was also working on a side hustle. I was doing fashion photography as a hobby, with the intention of going full time.

When the work week ended, my photography week began. Work was on its own computer and I never included any work communications in any of my personal devices. When we hit lockdown, everything was done from home. That said, they gave us iPhones for our regular telephone communications.

My time is mine. I earned raises and promotions, and had benefits based on my desires. I worked my schedule. If someone scheduled a meeting during a time when I was off, I would discuss that with the person. If I was needed, I'd attend; otherwise, it was my time off.

Yes we had Outlook, Teams, Slack for communications. I would stay connected during the work week, but when I was off, it was my time. My supervisors had ways to contact me in an emergency, and I let them know it was okay to do so in an emergency.

The fashion work ended, but it was one heck of an adventure! It was my time.

From the article: "The FAA is encouraging airlines to use bigger aircraft with fewer take-offs and landings." I worked in ATC R&D for many years. NY Tracon, N90, is crazy busy and very complicated. DCA handles lots of Regional Jets. Each aircraft is an "operation". If you're an airline and can carry the same amount of passengers in fewer aircraft, re: fewer operations, you're at an advantage, and the system continues to work.

The airspace and airports with the available controllers can handle only so many operations, and the FAA will limit operations accordingly. The airlines can either let the FAA randomly deny flights, or they can say to the airlines, as they apparently did, "We can only handle so many operations. How do you want to do this?" In situations like this, airlines themselves can decide how they're going to change their operations. In NY, it's probably easier to use/lease larger aircraft. Yes Teteboro, TEB, could take some traffic if this were just airport operations limited, but I suspect it is an N90 issue, so offloading to TEB really isn't an option. With DCA, it's more likely the airport. Airlines like United can offload to Dulles, IAD. Additionally, the airlines could even work with each other to some degree to get through this. They do that in significant weather events, though this is a much bigger event than a snowstorm at someplace like O'Hare (ORD).

fuckcensorship: "During depressive episodes, I have no interest in connecting with other people. This includes friends, therapists, family, etc. So the idea that I would ever pick up the phone and call a suicide hotline to talk to someone on the phone about my depression is borderline laughable."

cpill: "yeah, but clearly you haven't committed suicide yet, so maybe you don't really know what is like to _really_ want to kill yourself? I knew someone who did do it and they did want to connect every time they tried, even the last one."

cpill, it's good your friend wanted to connect on every attempt they made. Not all people are like that. Additionally, saying that a person who doesn't actually kill themself doesn't know what it is like to want to kill themself suggests a lack of knowledge on your part. There are people who cry out for help; there are also people who simply exit.

fuckcensorship, I grok.

It is a sad, soulless world in which we live today. I went to an otherwise anonymous state college on the east coast in the latter 1970s. One of the fun things I remember was picking up lunch from McDonalds using my former roommate's Ford Pinto. If you're not familiar with the Pinto, look it up. It was a "great" car. Yeah.

Driving to McDonalds was fun and exciting! This Pinto was a 4 speed manual, where the shifter could easily be lifted out of the drive shaft tunnel. But that was trivial in comparison to the fact the brakes were limited to the parking brake. The drive to MickyD's was five to ten miles, including travel on a highway. You plan your stops. A real emergency would be bad, but regular driving was merely interesting. When I got back to my former roommate's house, we enjoyed a great lunch! The drive was fun.

I'm saddened by what Stanford has become. I look at the list of companies founded by Stanford Alumni, and am duly impressed. I look at what the "edges" of the Stanford population is today, and see the end of Stanford dominance.

Here are your choices about life. It's wobbling on two wheels until you get it right or depending on training wheels and helmets to keep you safe. It's taking risks or saying, "Mommy, may I?" Mommy's gonna say, "No, honey, I don't want you to get hurt or for you to hurt anyone else."

Training wheels and Mommy's protection?

Fuck that.

Take 10 minutes to model it and you'll find there is no benefit in changing. As a couple others have pointed out, it isn't the Monte Hall problem.

Below I did two runs with a million cases. One envelope has 1 unit; the other has 2 units. I shuffle the envelopes, and the "player" chooses an envelope. "noChange" means this is the payoff if the player doesn't switch envelopes. "yaChange" means this is the payoff if the player switches envelopes.

$ python3 ./twoEnvelopes_00.py 1000000 noChange = 1500023 yaChange = 1499977

$ python3 ./twoEnvelopes_00.py 1000000 noChange = 1499984 yaChange = 1500016

When modeling Monte Hall, the payoff for changing is obvious.

For a bit of background, go to: https://x.company/projects/loon/

I was working on the Air Traffic Control side of unmanned free balloons in 2020, and Loon was an exciting project. While it's a shame it wasn't financially viable, they had it working with up to 60-ish balloons in the stratosphere at any given time. This was an amazing accomplishment.

The navigation was equally amazing. It was Loon who did some real research on stratospheric weather. While many meteorological entities throughout the world knew and understood tropospheric weather, the stratosphere was mostly unknown. In addition to AI, Google really did expand the knowledge and science of stratospheric weather.

We had our first and only at 40. (My wife is two days younger than me.) I retired a year ago, and our daughter is approaching a quarter of a century old. That was a miracle in itself as she almost didn't make it past hour one.

I loved this essay, saved it even. It's how I've lived my life for all of the days since our daughter's birth. I'm reluctant to say it's how I lived all of the years before that, as I wasn't as aware of time and of my mortality. That said, I had a sense my average life would be 75 years, and privately celebrated my 37.5 year birthday.

Paul Graham has at least two essays related to this: http://paulgraham.com/vb.html http://paulgraham.com/kids.html

For me, I consider my life as a book. There's a chapter where I would read the Wizard of Oz books to our daughter most nights. We went through the set of 15 books three times, and then it stopped. There's a chapter where I was doing fashion photography as a hobby for eight years. Me?! Yes! I even had two fashion shoots in Manhattan. There are many chapters of me working as a mathemagician, working on air traffic control R&D projects, one where I had to simulate stratospheric balloon trajectories and balloon control and navigation logic. I also had to learn a lot about stratospheric weather, which our in-house meteorologists had almost no experience.

I take essays like this and the two PG essays, and realize I have the chance to live a little more. This afternoon I'll be at the library while our daughter is working from home. I'll be continuing the writing of a story, may work on the migration from Freemind to Freeplane so that I can return to my personal work on the Traveling Salesman Problem. I'll grill dinner tonight for the family, will attend an in-person luncheon on Saturday, have an on-line chat with some folks in Berkeley Sunday night (I'm outside DC.)

The clock is ticking, the sand is flowing through the sandglass (I love that from Tom Scocca's essay!). The meaning of life is what we produce and what we create in the limited time we have. It's our mortality that establishes the context for meaning; it's what we do that is the actual meaning.

I worked with VRML in '96. It was fun and interesting. Our company even had a couple reps from SGI demonstrate it on an SGI O2 machine. The two companies at the time who were the main proponents were SGI and Sony, though SGI was clearly the primary commercial force behind VRML. SGI even produced a 3D animated "cartoon" twice a week called "Floops". Then one day in 1997 SGI announced they were no longer supporting VRML, and it was over. I personally walked away from it right then.

Was VRML cool? Yes! Was it clunky? Yes. VRML had all the finesse of XML, but it worked. If you could think in 3D, you could create items fairly easily in VRML. On a Windows 95 machine (good heavens!) using Netscape with a plug-in, moving through a VRML world was not fast or smooth, but it was doable. I created a 3D version of my office to show my managers what was possible, and discussed how we might actually do some things with it.

Yes there are posts here indicating VRML is being used today. For all practical purposes however, it's dead and has been for a quarter century.

Here's what I did and/or do.

1. I constantly ask trusted friends and family members if I was blundering in social situations. I asked my wife this evening, when our daughter had her boyfriend over for dinner. I didn't blunder. I asked anyway. I will ask during an event, especially if it lasts for hours. Ultimately when I blunder, I reprogram how I will respond when that situation arises again. While that could be a thousand little actions, I find I can generalize things, and that makes it easier.

2. Put yourself in tough social situations. I did fashion photography for 8 years as a hobby. I worked with 20+ models in the DC area, and did 2 shoots in NYC. Yes it was all about getting the photos, but to do that you focus your attention on the model. This book helped: "How to Win Friends & Influence People" by Dale Carnegie. Ultimately, the intimidatingly gorgeous woman in front of you and your camera is a regular human who comes from some place, has family and friends, and has interests. When you work with someone like that for 8 or so hours, you need to make her feel comfortable.

3. Work with some successful and highly extraverted people, whether in business or in a volunteer situation. I was working with and being mentored by someone who owned the world. There were no limitations with him. He could go anywhere, do anything. Obviously he didn't actually own the world, but his presence said he did. This was in a volunteer situation. This person was very hard working, wealthy, an overall good person, but took no garbage from anyone. He was also very smart. Actually there were a couple others like him in that volunteer situation - power, money, capabilities, responsibilities, accomplishments. Learn from them.

Good luck! This is what I did. You'll always feel socially awkward, but if you work at it, you can power through it in the tough situations. Hope this helps!

At my old company, Hadoop, JSON, Parquet were the solutions looking for a problem to solve. Yes we handled lots of data, but none of it was time critical. No matter, we had BIG DATA™. Bow when I say that. We weren't Google or Twitter. We were not surgically retrieving data, and while we had lots of data, we didn't have huge data centers; Dremel wasn't relevant to us.

It's funny! It would take our Hadoop team three weeks to get data together for our use. I often didn't have three weeks. In those times when I needed to use the data from the previous day, I'd just grab the raw data, organize it, process it, and be done with it in a few hours, using Unix/Linux tools and a bit of mathemagical wizardry.

"You're supposed to use Hadoop."

"You wanted to know what happened yesterday."

"I did!"

"If you want it from Hadoop, it will be ready in three weeks. Probably. That's if they have everything done."

Actually, you're right. You made very good points here. I always assume other people are rational. While many are, many are not, and I often forget the latter. Thank you.

Fuck YouTube. If they're going to control what news I get, I'll choose other than YouTube. I do not need them. I have read from both hard left and hard right, and am intelligent enough to make my own decisions about what makes sense. Let them play their games, whether silly or dangerous. I form my own opinions. Losers!

Sigh

I was in Australia when I read a piece from him on Desert Shield/Storm in an Aussie newspaper. I saved it. A few years later he was to sign books in DC, and I brought along the paper. He signed my book, and also signed the paper. I'd told him I'd seen it while in Australia. He said, "I wonder if I got paid for that?"

RIP, PJ. Thanks for the laughs and the insights.

My "to-do" list is a Freemind (and soon-to-be Freeplane) mind map. It's my calendar, my to-do-list, my project planner, my external brain. When I need to write something down, it goes to the mind map or a piece of paper where that information will go later to the mind map.

What about those things that never seem to come off the mind map? If it stays on the map too long without completion, I realize it's something I'm never going to do and I simply delete it. I never look back.
