I don’t use Skype – I want to stop the pop-up

I have Ubuntu 20.4. Just recently when I turn on my laptop, I get a Skype pop-up. This is the same window as if I click on the skype icon. I am not wanting to use Skype. How can I stop it popping up? This has only been happening since a recent ubuntu software update.

dnd 5e – Sleet Storm: do crampons stop you from falling prone?

The 3rd level spell Sleet Storm has the following effect:

The ground in the area is covered with slick ice, making it difficult terrain. When a creature enters the spell’s area for the first time on a turn or starts its turn there, it must make a Dexterity saving throw. On a failed save, it falls prone.

Crampons (price: 2 gp) provide the following benefit:

A crampon is a metal plate with spikes that is strapped to the sole of a boot. A creature wearing crampons can’t fall prone while moving across slippery ice.

Does wearing crampons mean the Sleet Storm spell can’t knock you prone?

How do aliens without the Medicine Skill stop the bleeding condition?

According to Starfinder’s bleeding condition rules:

You take the listed amount of damage at the beginning of your turn each round until this condition ends. Your bleeding can be stopped with a successful DC 15 Medicine check as a standard action, or through the application of any ability that restores Hit Points.

Some aliens have innate capabilities that allow them to restore hit points and can stop the bleeding in this way. Other aliens have the Medicine skill (or an ally with the Medicine skill) and can thus stop the bleeding that way. But what about unintelligent monsters, or aliens that simply have no medical training? Are they doomed if they get the bleeding condition and don’t have some capable healer at hand to stop the bleeding?

Getting Tripwire to stop complaining about apt upgrades

We use tripwire on Ubuntu servers to monitor integrity of key files. We regularly update packages with apt and end up with noise from tripwire because staff find it is a hassle to update tripwire with knowledge of approved changes we have made.

Is there a script that we could use that would wrap our apt update; apt upgrade with some tripwire commands that would abort before starting the apt upgrades if there was a problem known by tripwire (of a certain level), and commit any changes made by apt upgrade to the tripwire known baseline state after the upgrade? I realize there might be an intrusion during the apt upgrade that changed some other file, but would reluctantly be willing to live with that to reduce the noise from tripwire problems.

We would like to be running apt to auto upgrade every night, but currently run it manually when prompted by some incinga monitoring we have set up.

This seems like a common workflow but I can’t find a script for it.

unity – How can I make the transform to stop slowly smooth before the next waypoint?

You’re moving the object using Vector3.Lerp(). When you move with linear interpolation (lerp), the speed is constant. To add speed up at the beginning or slow down at the end, you’d need to use easing.

Ironically the source you obtained this code from seems to have left a comment referencing easing but then forgotten to actually include the easing section.

There are many ways to implement easing. One way is to use easing functions. You can search the web to find free libraries of easing functions for Unity. You’d generally use them something like this:

var t = passedTime / duration;
var lerpFactor = EasingLibrary.EaseInOutCubic(t);
transform.position = Vector3.Lerp(currentPosition, currentWaypoint.position, lerpFactor);

Another solution is to use an Animation Curve. With this approach, you’d declare a curve field at the top of your script:

(SerializeField) private AnimationCurve easingCurve;

This will show a curve field in the Inspector. We’ll use this curve to define the interpolated motion of our GameObject. Start with something like this (note that the curve should start at (0,0) and end at (1,1):

Easing curve

Then we’ll use the curve in our movement coroutine:

do {
    var t = passedTime / duration;
    var lerpFactor = easingCurve.Evaluate(t); //use the curve to apply easing
    transform.position = Vector3.Lerp(currentPosition, currentWaypoint.position, lerpFactor);
    passedTime += Time.deltaTime;
    yield return null;
} while (passedTime <= duration);

Our curve defines a function which takes an input and returns an output. The “time” (x-axis) of the curve represents the input (in our case, a time from 0 – 1) and the “value” (y-axis) represents the corresponding output (in our case, how far the GameObject has moved between the start and end positions).

If the curve was a perfectly straight line from (0,0) to (1,1) the output would be linear (in fact, it would be exactly the same value as the input). However, this s-shaped curve will ease the motion in at the beginning and ease it out at the end. The flatter the curve is in a particular area, the slower our motion will be at that time.

If you find this confusing, try messing around with the shape of the curve and study how this affects the animation.


Easing functions usually are easier to use. If there’s a specific style of easing that you want, you would just call the appropriate function. Animation curves take a little more work to set up but give you more control over the exact motion.

For a project which makes heavy use of easing, I’ll usually rely on an easing library and only use an animation curve if the easing functions don’t give me enough fine control. If I only need to use easing in one or two places, I’ll usually just use an animation curve rather than adding an easing library to the project.

display – How can I stop the system compensating for xrandr’s screen width setting?

I have an HDMI monitor connected, which overscans horizontally. I can’t see the extreme left or right of the desktop.

If I correct for this with, say,

xrandr --output HDMI-1 --transform 0.5,0,-50,0,1,-10,0,0,1

the horizontal and vertical translations work fine. But the scaling works only momentarily; immediately afterwards, the desktop redraws.

For example, suppose I scale the horizontal dimension by 0.5. Now the desktop takes up only half the screen. Then it redraws so that it takes up the full width of the screen again, but the width of each pixel remains the same as I set (so that the characters are half as wide).

How do I tell it to stop doing that? I’m running a GNOME desktop on focal.

scripting – Make different Mathematica notebooks stop talking to each other

So basically I am working in two completely different notebooks. But, if I define something in one notebook, it will overwrite the same definition in my other document.

Somehow these files talk to each other. I want to be able to use the same name for different functions in different documents. Any ideas on how I can get the different documents to stop sync with each other?
