The short answer is to measure methane you rely on methane absorption features. To do that you need to be looking at a source through the methane plume, from a satellite this source is the ground. From a ground instrument you can use the sun as a source, but it limits the times of day/direction/location you can measure from.
From a user point of view Python packaging has probably never been better, but it is still a huge mess from anyone having to maintain these projects which might explain some of the dichotomy in the comments.
In my experience most of these packaging tools work fine for pure Python packages, it is when you try and bundle extensions in a cross-platform way that things get really messy. For better or worse I think third party package managers somewhat outside the Python ecosystem, i.e. conda + conda-forge, are the only tools that get this right.
A lot of package managers that distribute binaries (e.g. conda-forge) rely on CentOS 7 because of the relatively old glibc version available, I wonder what all of these projects are planning on moving on to
Base Fortran has a lot of advantages for scientific programming over other languages, but I think there are two factors that are contributing to it's unpopularity:
1. Models are increasingly becoming much larger projects where flexibility, configuration, setup, are just as important as the actual number crunching that's done. These aren't areas that Fortran is known for.
2. The existence of libraries like Eigen for c++ provide most, if not close to all, of the advantages that Fortran gives for number crunching.
I was starting to get wrist pain in my right hand at the end of the day. I believed it was from never learning to type properly, I only used two fingers on my right hand even though I could type relatively fast.
I tried many times to re-train myself to type properly, but with proper technique I was only typing at half of my normal speed and would give up quickly.
In the end I switched to colemak to force myself to re-learn how to type with proper hand technique. It took a year but now I can type faster than I used to be able to with QWERTY and without any pain. It was definitely worth it for me, but there are enough annoyances with everything being QWERTY by default that I wouldn't recommend anyone make the switch without a reason to do so.
I had the same experience switching to Dvorak. It forced me to relearn how to type, and when I was relearning, I made sure to learn properly. The switch, and relearning to type, 95% solved my RSI problems.
> It does seem odd they would want to set up a lab in close proximity to what they wanted to study
The lab was nowhere near the site of what they were studying.
The coronavirus strains came from a cave 600 miles away and brought to Wuhan for further study.
Again, none of these viruses have a unique furin cleavage site for ACE-2.
If you read the FOIA document requests, one of the people who got grant money said "I just can’t figure out how this gets accomplished in nature . . . it’s stunning. Of course, in the lab it would be easy to generate the perfect 12 base insert that you wanted.”.
This person afterwards did a complete u-turn and signed onto the infamous publication in The Lancet. A lot of people quickly did a u-turn around the exact same time.

The best theory I've come across is that patient zero was a person collecting bats in caves for the lab in Wuhan. By all records, they wore woefully inadequate PPE (unlike the people in the lab itself who had well-established procedures).
This theory explains the jump from animal to human, the geographic origin, the reason why China didn't allow any outside investigations, and why most geneticists believe it likely had a zoological origin. (Yes, that last bit remains true no matter how badly the conspiracy theorists want it to be false.)
Whenever I see a claim of this type, I always wonder how you back it up?
I'm not saying that most geneticists don't believe what you're saying, because I have no clue what most members of any profession believe about anything. I have plenty of gut feelings, but how do you go beyond that?
Did you mean most geneticists that you know? That you've seen articles from?
> The best theory I've come across is that patient zero was a person collecting bats in caves for the lab in Wuhan.
There are literally millions of people in China who live in close proximity to bats. You don't have to invoke the 1-in-a-million lab worker here (who will be much more careful than the other 999,999 people, anyways). There are literally people who go shovel bat poop out of caves for a living. Then there are all the millions of farmed animals that have contact with bats - this is how the original SARS got into people.
A lab worker getting infected in a cave and then going back to Wuhan is not the best theory. It's an extremely improbable explanation for the pandemic, when you realize just how much contact people and farmed animals have with bats.
I have found that there can be huge quality differences between cheap and more expensive LED bulbs as well. Specifically the ones that use a cheap rectifier. Sometimes I think that I can see them flickering out of the corner of my eye.
This is a big part of it. I tend to pay a reasonable amount for my LEDs and I've yet to be disappointed. I very rarely replace bulbs despite having dozens of fixtures, and the quality of the light is good because I made a point of buying the right colour temp and getting dimmable ones where it makes sense.
Unfortunately the market is swamped with cheap low quality ones that produce pretty crap quality light and burn out quickly. I learnt pretty quickly that it was a false economy to skimp on them.
It would be interesting to see some example questions and answers. Since the test is multiple choice is it possible that the model has gotten very good at estimating how likely a possible answer is?
Annualized over the last 6 months inflation is now under the 2% target. I would be surprised if we see anything more than a quarter-point at the next meeting.
I couldn't find this particular piece of data published anywhere, but I did a little math and arrived at an annualized rate of inflation for the last 6 months of 5.85%, well above the 2% target.
Sulfur dioxide in the troposphere isn’t very long lived and won’t make it to the stratosphere where it actually has a surface cooling effect. Even small volcanos have very little impact on stratospheric aerosol formation since they do not inject sulfur to high enough altitudes. Only very powerful surface injections have long lasting stratospheric effects.
