Every time, over the years, that there has been some kind of headline saying renewables have overtaken fossil fuels, when you look at it a bit more closely there is always a big 'but'. For example, it was compared to coal (not taking into account electricity from gas), or it was for one day, or it was a percentage of new installations, or it excludes winter, includes nuclear etc.
This time, however, it looks like it's actually true and that's just for wind and solar. This is incredible, and done through slowly compounding gains that didn't cause massive economic hardships along the way.
The only medication I know about that some people on the spectrum take are antipsychotics and that's for specific situations, but maybe if you're in that situation life seems even more like a dystopian text based adventure game.
I love it, I have been meaning to put together a similar simulation to demonstrate the effects of interruptions and context switches on developers.
Something like the following:
- a game or puzzle which requires working memory, like matching pairs or some puzzles that need a lot of working memory and/or flipping between screens
- this gets interrupted by fullscreen interruptions of someone's face, and text asking questions, or announcing something, and you have to pick an answer or a reaction (multiple choice)
- it could start with questions like 'hi, are you busy?' or 'can I ask you a question?'
- answers which tries to end the conversation quickly could lead to even more demanding reactions or questions
- interruptions stating there is an emergency can lead to a lot of questions and answers which then leads you to discover than it is in fact not an emergency
- once one of these engagements finish you can return to the game and try to complete it
- you'll get multiple interruptions like this
- other interruptions can also flash up, like a notification that a meeting is due in x minutes
- it could then have a short simulated meeting, perhaps just a line by line scroll of dialogue between others, where you need to say nothing
- however, at some point someone will ask you directly about one of the items discussed, and you will be given a set of fairly ambiguous multiple choice answers which you will have to try out until you get to the 'correct' one
- at the end of the meeting you return to the working memory task/game
- this gets interrupted by someone then asking you about the action points in the meeting
- return to the game
- get notifications about the end of your work day coming up
Fortunately it mentions early on in the article that this is related to an Olympus camera so I'm guessing this has something to do with the OM system's flavor of Olympus's proprietary ORF format.
I don't know what other people do, but I think the better option would be to set vm.swappiness to 0. Swap space is a good safety valve. You should never really have to use it, so a good way to detect that something is going really wrong and take action before it brings the system is down is by looking at when swap is busy filling up.
Also if someone opens up an application that grabs huge chunks of RAM but leave a lot of it idle, and turn swap off completely, they should not be surprised. I don't know why people see this as a bug, but perhaps I've just been spending time in the UNIX family tree for too many decades.
The most common cause here is something causing a situation where some queries hang or takes a long time to complete, while also locking access to something, while new queries keep coming in. This builds up quickly.
A good way to catch this would be to have something log the list of running queries every couple of seconds. Look at this log after the crash and you'll hopefully be able to identify which are the long running processes, and which are the regular queries that builds up.
To fix it would be a combination of making the queries that cause the locking to be less like that, also perhaps putting in a limit on how many queries can build up and also implement a way for the regular queries that build up to time out or fail quicker or more gracefully.
