This is fantastic advice. At the first startup I worked at, we had several issues with our MySQL dbs & ETL jobs (MyISAM table locks, slow updates, no replication) - I spent a few days just reading the relevant sections of "High Performance MySQL: Optimization, Backups, Replication, and More" - and voila I had solid recommendations built on facts rather than random opinions people created over the years - put my career on an entirely different trajectory.
- It is passively cooled rather than using an expendable coolant- "SPHEREx relies on an entirely passive cooling system — no electricity or coolants are used, simplifying the spacecraft’s design and operational needs."
- It is a Medium-Class Explorers (MIDEX) mission - Investigations characterized by definition, development, mission operations, and data analysis costs not to exceed $180 to $200 million total cost to NASA.
I think the cost of ground support eats into the budget length. The original estimate for project was $241M, so it was a large MIDEX
- It is in a Polar orbit around Earth at the day-night (terminator) line
Possibly stupid question: how does this polar orbit stay over the terminator? And how is the terminator defined for a polar orbit here, since both the north and south poles are on the terminator only at the equinoxes?
>how does this polar orbit stay over the terminator?
Because it's launched at a angle greater than a straight north-south 90 degree orbit, so orbital precession will correctly follow the terminator. Depending on the orbital altitude this can be more than 140 degrees: https://en.wikipedia.org/wiki/Sun-synchronous_orbit
ah, I misread the Orbital Parameters on the wiki. that day-night orbit is also a LEO which makes it even more possible to do a manned mission for upgrades. Oh, wait, we no longer have a shuttle for those types of missions.
Remember, it is passively cooled (a major design plus and, I assume, part of why it was able to achieve the cost it did). So there would be no need for a manned mission. And in fact, at that cost, it wouldn’t make sense anyway.
Dragon lacks a Remote Manipulator System (Robot Arm) and a airlock. things that make servicing objects in space a lot easier. Im sure somewhere at NASA or SpaceX there is rough set of specs on what a shuttle like starship would look like complete with payload bay, robot arm, and eva airlock.
If you're alluding to Russia, they've had them. They even failed in making their version of a shuttle. With what money would they do anything with now?
If you're alluding to China, they probably had the data from the Russians anyways.
> They even failed in making their version of a shuttle.
Nitpick: It was sort of successful. They built a shuttle, and it successfully flew a single (un-crewed) mission of a couple orbits. The collapse of the USSR / lack of funding killed it.
It's amazing how all it takes is a few threats of annexation, and for GOP thought-leaders like Ben Shapiro to start talking about enslaving you[1] to work on the Panama Canal to make another country rethink its relationship with you.
Absolute animals. As is anyone else carrying water for these politics. There's no excuse for it.
If you had anything at all to do with putting these clowns in power - reign them back in. They are supposed to work for you. Remind them of this.
I don't want to quibble just to be contrarian. Polaris Dawn was at the International Space Station's inclination, 52°, which is the most common destination for human astronauts. Isn't usually considered a polar orbit.
I want rather to clarify a really neat point, about what the other mission's doing. From KSC, you can conventionally only launch to inclinations below 62° [0] (constrained by populated landmasses). To get to a true polar orbit from Florida, that means they have to attempt a curved launch [1]—something that's pretty rare, and (to my knowledge) Falcon itself never tried before. (The parent comment was right to ask whether a polar orbit is possible: it does create interesting challenges).
Created by NASA with consulting from Carl Sagen, and his wife, Ann Druyan, contained two culturally important works of music: Johnny B. Good, and The Well-Tempered Clavier - Bach, by Glenn Gould.
There was a cartoon, in OMNI magazine, were two scientists look at each other after decoding the first S.E.T.I Message: "Send More chuck Berry."
To motivate deep space travel we should decide these records are dangerous and try to track them down (after voyager is out of range for radio control).
If you have a judge system, and Mistral performs well on other tests, wouldn't you want to include it so if it scores the highest by your judges ranking it would select the most accurate result? Or are you saying that mistral's image markdown would score higher on your judge score?
We'll definitely be doing more tests, but the results I got on the complex tests would result in a lower score and might not be worth the extra cost of the judgement itself.
In our current setup Gemini wins most often. We enter multiple generations from each model into the 'tournament', sometimes one generation from gemini could be at the top while another in the bottom, for the same tournament.
It looks like CGC - one of the big card graders - has touted their ability to grade some very early Pokemon The Card Game playing cards (even alpha test cards printed in very low numbers). Here is their grading scale on their site https://www.cgccards.com/news/article/13347/
People have purchased these CGC cards on ebay assuming they were legit based on the above certifications. It looks like total cards is something like 6 test decks of 26 cards of the alpha prototype - so the rarest example is fairly small, but I think it goes up as they got to later pre-release versions. Furthermore, there are some cards that were signed by Akabane (a co-creator of the game) and those have the presence of the yellow dots - meaning those are most likely not legit pre-production cards. One of those signed cards was sold for $200k I believe - https://www.cgccards.uk/news/article/13661/
So total financial impact of this directly in low millions?
Thank you! Looks like CGC is in a tough spot. The grading guide struck me as quite vague.
> CGC Cards utilized all the tools at our disposal to help document and authenticate these cards, compiling vast resources for comparison with future submissions. A very thorough process is in place for the authentication and grading of these cards using ones verified by Mr. Akabane.
In an ideal world, it seems like there should be publicly shared, repeatable methods/standards for authenticating cards to avoid issues (whether complicit or an honest mistake) like this from a single central authority.
Is anyone aware of a site that shows various builds or off the shelf systems (new and old) and how they handle various models? Like I’d love to see the above vs a Mac Studio 198gb vs an old m1 studio vs other models. I don’t have $6000, but what is a good happy medium I could get to on a used system with a smaller model.
