How to get a rolling recording into disk, with a maximum age?Context
When something goes bad in my server, I want to be able to dump the profiling information of the hours prior and analyse it, to know what went wrong.
- As I don't know when things will go bad, the JDK should be continuously saving the events to disk.
- As the server is not rebooted often, to avoid the files growing unbounded, I need to set some sort of cap (either age, or size).
So, in other words, I wanted the JDK to save the recordings continuously to disk, but remove the older files/recordings such that the total amount remains under a certain threshold (age or size).
To that end, these are the options I have for version
Oracle JDK 1.8.0_144:

The problem, I think, is that you are starting two recordings, one with
-XX:StartFlightRecording and one with
The one with
-XX:StartFlightRecording is unbounded. I think the following would be appropriate option for Oracle JDK 1.8.0_144 and your use case:

I think the problem is that you are trying to use the deprecated babel-eslint parser, last updated a year ago, which looks like it doesn't support ES6 modules. Updating to the latest parser seems to work, at least for simple linting.
So, do this:
- In package.json, update the line
"@babel/eslint-parser": "^7.5.4",. This works with the code above but it may be better to use the latest version, which at the time of writing is 7.16.3.
npm ifrom a terminal/command prompt in the folder
- In .eslintrc, update the parser line
- In .eslintrc, add
"requireConfigFile": false,to the parserOptions section (underneath
"ecmaVersion": 8,) (I needed this or babel was looking for config files I don't have)
- Run the command to lint a file
Then, for me with just your two configuration files, the error goes away and I get appropriate linting errors.
Recently I face an issues to install my dependencies using latest Node and NPM on my MacBook Air M1 machine. Then I found out M1 is not supported latest Node version. So my solution, to using NVM and change them to Node v14.16
Everything works well, but when our team apply new eslint configuration. Yet, I still not sure whether eslint was causes the error or not..eslintrc ...

I had a similar problem with another module.
The solution I found was to update both node (to v16) and npm (to v8).
For Node, I used brew (but nvm should be OK).
For npm, I used what the official doc says :
npm install -g npm@latest
I'm getting this error:...

Please, consider trying to follow the instruction from quarkus/faq.adoc at main · quarkusio/quarkus:
1. Native compilation
Native executable fails on macOS with
error: unknown type name 'uint8_t'
Your macOS has the wrong
*.hfiles compared to the OS and no gcc compilation will work. This can happen when you migrate from versions of the OS. See Cannot compile any C++ programs; error: unknown type name 'uint8_t'
The solution is to
sudo mv /usr/local/include /usr/local/include.old
- Reinstall XCode for good measure
brew install llvm
- generally reinstall your brew dependencies with native compilation
The executable should work now.
The purpose of (the idea behind) renaming the
include directory (from
include.old) seems to be explained in the answer.

I'm planning to move away from Docker to Podman. I use docker-compose a lot so am planning to switch to podman-compose as well.
However I'm stuck at the simplest of podman examples, I can't seem to mount a volume onto my container? Obviously I'm doing something wrong however I cant figure out what it is.
My source file definitely exists on my (hardware) host (so not the podman machine). but I keep getting the error 'no such file or directory'.
Funny thing is if I manually create the same file locally on the podman machine (podman machine ssh --> touch /tmp/test.txt) it works perfectly fine.
- should I (manually?) mount all my local files onto the Fedora VM (podman machine) so that in turn this Fedora mount can be used in my actual container? and if so, how do I do this?
podman runcmd below should work and there is something else I'm doing wrong?

As mentioned by @ErikSjölund there has been an active treat on https://github.com/containers/podman. Apparantely Centos (Podman Machine) does not (yet) support different types of volume creation on the machine.
It's not perse Podman lacking this feature it's waiting for CentOS to support this feature as well.
However, should you want to mount a local directory onto the machine I recommend have a look at https://github.com/containers/podman/issues/8016#issuecomment-995242552. It describes how to do a read-only mount on CoreOS (or break compatibility with local version).
I have been experimenting with full responsive layouts between desktops, tablet, and mobile phone sizes for a bit but am having trouble with the layout below.
I was using a grid layout from bootstrap but since it is two columns, as the width shrinks, the second column of two goes below the left, main content section. I want to split it up as the screen caps below state.
This is the starting view:
This is what I want to happen:
This would be the mobile phone view:
So the wide view will get shrunk during testing and I want it to jump to the mobile view where the top side bar goes above the main content and matches the width of the main content while the bottom sidebar does the same thing to the bottom.
It is easy to put both sidebars on the bottom but I want to try to figure out the possibility of splitting it up.

You may want to try out Bootstrap's Flex order utility to achieve the desired result
Also, share a code example so others can see what you have already tried, I believe you may face some issues even with Flex's Order utility, but that depends on your HTML structure.
For such layout my preference would be to create a copy of the top column for mobile / desktop, and use
d- utility to show hide the right one.

I’m writing a pretty complex app in React/Redux/Redux Toolkit, and I came across a situation which I’m not really sure how to handle. I found a way to do it, but I’m wondering if it can cause issues or if there is a better way. The short version is that I want the reducer to communicate to the caller without modifying the state, and the only way I’ve found is to mutate the action.
To simplify, let’s say that I want to implement a horizontal scrollbar (but in reality it’s significantly more complicated). The state contains the current position, a number capped between some
max values, and the UI draws a rectangle that has that position and that can be clicked and dragged horizontally.
Main property: If the user clicks and drags further than the min/max value, then the rectangle does not move further, but if the user then moves in the other direction, the rectangle should wait until the mouse is back at its original position before starting to move back (exactly like scrollbars behave on most/all operating system).
Keep in mind that my real use case is significantly more complex, I have a dozen of similar situations, sometimes capping between min and max, sometimes snapping every 100 pixels, sometimes more complicated constraints that depend on various parts of the state, etc. I’d like a solution that works in all such cases and that preserves the separation between the UI and the logic.
- I do not want the UI/component/custom hook to have the responsibility to compute when we reach the min/max, because in my use case it can be pretty complex and depend on various parts of the state. So the reducer is the only place that knows whether we did reach the min/max.
- On the other hand, in order to implement the Main property above, I do need to somehow remember where we clicked on the rectangle, or how many pixels of a given "drag" action was handled, in order to know when to start moving back. But I don’t want to store that in the state as it’s really a UI detail that doesn’t belong there (and also because I have quite a few different situations where I need to do that and my state would become significantly more complex, and unnecessary state changes will be performance heavy).
So the reducer is the only part that knows if we reached the min/max, and the only way a reducer usually communicates to the rest of the app is through the state, but I don’t want to communicate that information through the state.
I actually managed to find a way to solve it, which seems to work just fine but feels somewhat wrong: mutating the action object in the reducer.
The reducer takes the action "dragged by 10 pixels", realizes that it can only drag by 3 pixels, creates a new state where it has been dragged by 3 pixels, and adds an
action.response = 3 field to the action.
Then after my custom hook dispatched the "dragged by 10 pixels" action, it looks at the
action.response field of the return value of
dispatch to know how much was actually handled, and it remembers the difference with the expected value (in this case it remembers that we are 7 pixels away from the original position).
In this way, if at the next mousemove we drag by -9 pixels, my custom hook can add that number to the 7 pixels it remembers, and tell the reducer that we only moved by -2 pixels.
It seems to me that this solution preserves separation of UI/logic perfectly:
- The reducer only needs to know by how many pixels we moved and then return the new state and how many pixels were actually handled (through mutating the action)
- The custom hook can remember how far off we are from the original position (without having to know why), and then it will simply correct
event.movementXto compensate with how much the reducer didn’t handle in previous actions, and then send the correct delta to the reducer.
It also works just fine with things like snapping at every 100 pixels or such.
The only weird thing is that the reducer mutates the action, which I would assume is not supposed to happen as it should be a pure function, but I couldn’t find any issue with it so far. The app just works, Redux Toolkit doesn’t complain, and the devtools work just fine as well.
Is there any issue with this solution?
Is there another way it could be done?...
ANSWERAnswered 2021-Nov-19 at 16:23
At a technical level, I can see how this could work. But I'd also agree it feels "icky". Very technically speaking, mutating the action itself qualifies as a "side effect", although it's not one that would meaningfully break the rest of the app.
It sounds as if the key bit of logic here is more at the "dispatch an action" level. I think you could likely call
getState() before and after the dispatch to compare the results, and derive the additional needed data that way. In fact, this might be a good use case for a thunk:
