Are class skills picked before or after your character’s Background is selected?

In the Backgrounds section:

Each background gives a character proficiency in two skills. Skills are described in chapter 7. In addition, most backgrounds give a character proficiency with one or more tools. Tools and tool proficiencies are detailed in chapter 5. If a character would gain the same proficiency from two different sources, he or she can choose a different proficiency of the same kind (skill or tool) instead.

Could a Barbarian character being created, for instance, pick Athletics and Survival as his class skills, and then when selecting a background, pick Outlander (which grants proficiency in these two skills), and then using this rule, instead pick two skills from the whole skill list?

Or is your background chosen before class skill-proficiencies?

course suggestions to learn background for sensor fusion

Specifically what topics in probability would give me the background I need to understand sensor fusion?

I’m looking for a college class that would include these topics, so I’m wondering what the class might be called or what might be in the description.

By any chance do you know of a community college that offers a good class that would cover these topics?

To explain a bit more, I’m a rising sophomore computer science major, but I’m on leave from my university because of the pandemic. I want to take a class in the meantime, and since many community colleges are online at this point, I have many options, but I’m not sure exactly what I should be looking for.

Thanks for your help!

Does a PC with the Noble background need to supply equipment for their retainers?

Looking at the Noble Variant feature "Retainer":

You have the service of three retainers loyal to your family. These retainers can be attendants or messengers, and one might be a majordomo. Your retainers are commoners who can perform mundane tasks for you, but they do not fight for you, will not follow you into obviously dangerous areas (such as dungeons), and will leave if they are frequently endangered or abused.

From what I understand, this gives you a +1 minion and +2 non-fighting servants. However, that does come into question where their equipment would come from: Such as cooking utensils, tents, bedrolls, rations, weapons, clothing, etc.

Is it assumed that a servants would come equipped with their needs? (Such as a cook would have their tools, the majordomo would have his equipment, etc?)

How to check if Android app is taking pictures in the background? [migrated]

I have Android app that I found to be loading Camera in the background. It’s one of the most widely used internet browsers.

I been trying debug what is actually happening with LogCat in the Android Device Monitor. Couple of lines that catch my eye:

I/CameraManagerGlobal(24529): getCameraService: Reconnecting to camera service I/CameraService(331): getCameraCharacteristics: Switching to HAL1 shim implementation... I/NuPlayer(331): setDataSourceAsync(URL suppressed) I/CameraClient(331): Opening camera 1 E/QCamera2HWI(331): [KPI Perf] int qcamera::QCamera2HardwareInterface::openCamera(hw_device_t**): E PROFILE_OPEN_CAMERA camera id 1 I/QCameraHalWatchdog(331): Starting Watchdog Thread... E/mm-camera-intf(331): mm_camera_open: dev name = /dev/video2, cam_idx = 2 D/QCameraParameters(331): int32_t qcamera::QCameraParameters::initDefaultParameters(): supported pic sizes: 1280x960,1280x720,640x480,352x288 D/QCameraParameters(331): int32_t qcamera::QCameraParameters::setNumOfSnapshot(): nBurstNum = 1, nExpnum = 1 I/QCameraHalWatchdog(331): Stopped Watchdog Thread... I/CameraClient(331): Destroying camera 1 E/QCameraPostProc(331): int32_t qcamera::QCameraPostProcessor::deinit(): Jpeg closed, rc = 0, mJpegClientHandle = 7900 

How would I know if picture is actually taken?

Is this possibly normal behavior to check camera availability?

Acceptable background by level

Disclaimer: This has nothing to do with backgrounds from DND5.

It happens a lot that the story you create for your character sometimes is not as in point with what happens afterwards in-game. If you are a Lvl 1 Warrior you maybe can say you fought in the frontlines of a bloody war, and now are a retired mercenary.

Then you end-up losing to a bunch of rats the GM threw your way because the ceiling was too low and you forgot your matches.

What I want to know, is there a table/resource that has some indicator of what you may have accomplished when creating a character of a specific level?

That way I won’t embarrass myself narrating when I defeated a lich in my Lvl3 Ranger backstory, just to be inmediately destroyed by two goblins and their pet wolf in my first encounter.

I don’t mind DND/pathfinder responses, even when the power level may differ between the two, and even between versions, I’m more interested if the resource itself exists, or how to create one.

DVWA file upload background

I’ve just started in penetration testing with metasploitable and currently trying to learn file upload vulnerability present in DVWA module. I know that somehow upload is preventing files other than images to be uploaded but I don’t understand how. I tried to look page source of ‘upload file’ webpage but I don’t see any javascripts working there. Webpage only refers to a script which also doesn’t seem to have any filters for file being uploaded. Can someone please explain what exactly in the html or JavaScript of webpage is working as a filter?

Can Encode thoughts be acquired outside of the Dimir Background?

Encode thoughts is only, normally available to characters with the Dimir background.

Is it available to other characters who might get cantrips outside of traditional methods? Like Pact of the Tome or Magical secrets? My intuition is no, because they let you get cantrips off of class spell lists, but this cantrip is not on a class spell list.
