This means that Twitter increasingly pushes its users towards its For You feed, which is now going fully algorithmic, and will only include posts from verified (meaning ‘paying’) accounts. That means most accounts you follow won’t even be eligible to appear, and the others won’t appear often.
Looks like all accounts you follow will appear in For You after all, not just the ones that are verified:
Forgot to mention that accounts you follow directly will also be in For You, since you have explicitly asked for them
- Cars in a parking lot: they enter an leave mostly independently. The turnover time for residential parking might be a day or two. For a shopping center it is a few hours.
- Bugs in software: they get introduced and then fixed somewhat independently. The turnover time is on the order of weeks to months, maybe days if the project is very active, or even years for very subtle bugs.
- Water molecules in a lake: "new" ones flow in, get mixed up with the existing ones, and roughly independently flow out again. The turnover time depends on the influx/outflux and volume
- Stable equilibrium: The surface of a pond when I throw something in. I might be interested in the overall water level, which slowly changes over days and weeks. At these timescales the surface is always in equilibrium. (Equilibrates quickly re what I'm interested in)
- Bistability: The ruling party in a democracy. Mostly stable over a monthly to yearly timescale. I need to worry about who to vote for once every few years, not every day. (Equilibrates quickly re what I'm interested in)
- Dynamic equilibrium: The amount of train delays per day in a city. If I'm in
- The demand for toilet paper. On a short-term timescale there'll be random peaks and troughs (or not so random ones due to people expecting a lockdown). But in the medium-term it'll be constant, because of each person only needing a fairly constant amount of toilet paper. Although in the long-term there'll be changes again due to a growing or shrinking population.
- The amount of train delays per day in a city. Some days have more, e.g. because of some big event or a random accident, while other days have fewer. But on average over weeks or months it is roughl
I really like the chess example. Anything continuous that gets discretized is similar. Like the color of a pixel in a photo, or whether you have crossed the finish line in a race.
- A seesaw on a playground. Either side will come back down again if it's perturbed a little (given it's reasonably well oiled etc).
People sitting on it and literally kicking with their feet is enough to kick it into a different state. Random noise due to wind is not strong enough, except maybe in a heavy storm. - The handle of a window (usually). Pointing in one direction when closed and another when open. It will stay in either position unless explicitly moved (which makes it different from a door handle).
The activation energy required to kick it depends on w
- The even surface of a pond. If I throw in a stone it'll ripple for a while, but the additional activity will dissipate again.
- The number of tabs I have open in my browser. If it's very few I have no problem opening and keeping new ones. If it's too many, titles become hard to read etc. and I feel reluctant to keep open additional ones and tend to close a bunch of them at once.
- The amount of social interaction I get. Too little and I feel lonely and reach out to people. Too much and I feel overwhelmed and keep to myself for a while.
In economics (and I’m sure in many other fields - I’m just writing about what I know here), something like this is supposedly done in the “robustness checks” section of a paper.
Machine learning sometimes has ablation studies, where you remove various components of your system and rerun everything. To figure out whether the fancy new layer you added actually contributes to the overall performance.
Nice! I have a similar set of scripts for google cloud instances. And my favorite is also the resizing one. Just soo much more convenient than using the UI.
They also automatically mount an sshfs of the instance's home directory, which I found very helpful for e.g. working with output the instance produced that can't easily be interacted with in a terminal.
In case anyone is interested: gcloud-connect-instance, gcloud-change-type (but fair warning: I haven't used them in a while, and updates to the gcloud cli/api might have broken some things).
