Note: this entire discussion is exclusively about unchecked exceptions. Checked exceptions have nothing to do with what I am talking about here.

So, I have my Intellij IDEA debugger configured to only break on unhandled exceptions.

^{Of course this would not work without some extra love, because language constructs such as try-with-resources catch and rethrow, thus causing the debugger to break not at the point where the exception was thrown, but instead at the point where the exception is rethrown, which is useless, but I have gone through the trouble of putting in all the necessary extra love (I will spare you from the details) and I have gotten things to work reasonably well.}

So, when an exception is thrown anywhere within my code, I never have to guess what went wrong by poring through post-mortem stack traces in logs; I can see what went wrong by having the debugger stop right at the throw statement.

This all works reasonably well for the most part; specifically, it works reasonably well for as long as all the code involved is my code. unfortunately, sometimes I also have to deal with other people's code.

When I call Jim's function, which in turn calls my function, and my function throws, then quite often this exception is not treated as an unhandled exception, because Jim's function quite often contains a try-catch. When this happens, and depending on what Jim does in his try-catch statement, the debugger will either stop somewhere within Jim's code, or it will not stop at all, and there will be a stack trace in the log if I am lucky. In either case, my goal will not be met: the debugger will not stop on the throw statement.

For example, if I register an observer with Swing, and Swing invokes my observer, and my observer throws an exception which is unhandled as far as I am concerned, the exception will certainly not be unhandled as far as Swing is concerned, because Swing has a try-catch at the very least in the main loop of its Event Dispatcher Thread. So, the debugger will never break on the throw statement.

So, my question is:

Is there anything I can do to convince the debugger to stop on exceptions that are unhandled as far as I am concerned?

To put it in different terms: is there any way to let the debugger know what the boundaries of my code are, so that it can stop on exceptions that cross those boundaries?

Please note that I may not necessarily have freedom to change the throw statement: I may in turn be invoking yet a third library, which may be throwing the exception, or I may be invoking some code of mine which is general purpose, so its throw statement needs to stay as it is, because there probably exists some test which exercises that code to ensure that it throws the expected exception under the right circumstances.

I am using IntelliJ IDEA, if that matters.

Inspired by a recent question.

One use case for gcc-style inline assembly is to encode instructions neither compiler nor assembler are aware of. For example, I gave this example for how to use the rdrand instruction on a toolchain too old to support it:

I am checking out the mgcv package in R and I would like to know how to update a model based on new data. For example, suppose I have the following data and I am interested in fitting a cubic regression spline.

I am trying to plot two probability distributions onto the same plot. One is a uniform distribution with area under the curve = 1 and the other is a chi distribution (or to be more specific, a Maxwellian) with three degrees of freedom with area under the curve = 1. Here is my code so far:

I have the following problem. I would like to remove the noise from an IMU sensor. My clue would be a Kalman filter. In the Arduino IDE you could easily implement one via library. Now I would like to solve this by C# directly on the computer but I can't find a library on .NET 4 that works. I tried it with NugetPackages : MathNet. and Emgu.CV. Do you have alternatives that work on .NET 4.0 or do they even work, and if they do, does anyone have a good example? Have a nice day :)

EDIT: Adding Arduino IDE code

Best practice when analysing data from an RCT is to adjust for the baseline measure (ancova). However, researchers often still ask for change from baseline in each group and their relative difference (given by the treatment x time interaction). When one adjusts for the baseline measure, contrasts involving time can only be made from the first post-baseline measure.

Is there a way to perform a contrast where you subtract the model prediction at each post-treatment time point from the baseline measure (e.g. the overall pre-treatment mean of the combined groups)? I could do this manually but wouldn’t get C.I.'s.

Some dummy data are below:

EDIT [resolved]

based on the answer from Thingamabobs below, the approach simply turns out to be making sure the elements you spawn are allocated to correct parents.

It is worthwhile to create a frame just to hold every scrollable element since you can't move widgets around between parents when using pack/place. So a common parents between all movable elements will give you the freedom to move them around, again just create a holder frame. See the answer and discussion below for more details.

EDIT2

Bryan's answer below has very good info and an alternate approach using just a canvas. The core concepts still stand the same.

original question begins here

So based on this answer by Bryan, I used this approach to spawn widgets on a scrollable frame (which is basically a Canvas wrapping a frame inside as we know cause Frames don't have scroll attributes).

The widgets in this case are just tk.Buttons which I spawn in a loop using lambda to preserve state. That aspect is completely fine.

Now everything works fine except when I spawn more elements (again just buttons), they seem to be cut off. and I can't seem to scroll down to see the remaining ones. I am only able to scroll upwards only to see empty space.

please see the video below to see what I mean (excuse my horrible color choices, this is for a quick demo)

In the video, there are more elements below template47 but I can not scroll to them. I can scroll upwards but it's just lonely up there. All the names are actually buttons with zero bd and HLthickness.

To begin, my first instinct was to attach a ttk.scrollbar to the canvas+frame, which I did but observed the exact same behavior.

Then I tried to see if i could use .moveTo('1.0') to scroll down to last entry and then since upward scrolling works already, shouldn't have an issue. But this didn't do anything either. Still the elements were cut off, and it obviously messed up upward scrolling too.

I don't think I can use pack/grid geoManagers since as the answer by bryan i linked to above suggests, using place with its in_ arg is the preferred way. If it is possible otherwise, let me know though.

as depicted in the answer linked above, I also have two frames, and I'm using the on_click callback function to switch parents (a lot like in example code in answer). Turned out place was the best bet to achieve this. and it is, all of that aspect is working well. It's just the scroll thingy which doesn't work.

how i bind to mousewheel

I am using lm() on a training set of data that includes a polynomial. When I subset in advance with [ ] I get different coefficients compared to using the subset argument in the lm() function call. Why?
