ringtone – How can it be difficult for Google to separate the volume of notifications and ringtone on Android One

I'm tired of loud notification tones and the use of third-party software not optimized to control something as simple as the volume of notifications.

I believe Google has the most advanced technicians in the world. Why is scheduling a volume control mechanism a problem?

or are they deliberately trying to frustrate users of Android One?

xcode – The "Xcode_11_Beta.xip" archive can not be expanded because the selected volume does not have enough free space.

I'm downloading the new beta version of Xcode 11.

Once the file downloaded when I double-click to open it, I get this error.

The archive "Xcode_11_Beta.xip" can not be expanded because the selected volume does not have enough free space.

The Xcode 11 Beta occupies 7.66 GB, and 18.27 GB are available on my disk.
I've tried to download it twice and I get the same problem. I use MacOS Mojave 10.14.5 on a MacBook Air (13 inches, early 2015).

Why is google assistant at maximum volume with a Bluetooth headset?

No matter what I adjust the volume on my Bluetooth headset, when I use google assistant over it, the volume is at maximum. It is extremely unpleasant for my ears and I do not even have sensitive ears. I've tried adjusting the volume on both the headphones and on my phone, but nothing seems to change it. Even if I put everything in mute, the volume is always at maximum.

Has anyone experienced it and is there a way to solve this problem?

How to mount the root data volume on macOS 10.15 Beta 1 when started in single-user mode?

I need to reset my administrator password (https://apple.stackexchange.com/a/61932/17533). Can not boot into the recovery volume, so I have to start in single-user mode and change the data volume.

When starting in single-user mode, the system displays the following help:

To mount the root device read-write:
$ / bin / mount -X /

However, this leads to an error message:

mount: illegal option - X

I've also tried the old mount -uw -but that leads to firmlink related messages, and then I still do not have a recordable data area.

ascend shows that the volume of data has already risen to / System / Volumes / Data read only. Try to disassemble it with disassemble leads to an error "Operation not allowed".

mount -uw / dev / disk1s1 (which is the data partition as indicated by ascend) leads to the error "2 volumes found in the group … Could not stat file // AppleInternal, error No file or directory of this type".

Can not access the new volume? when I ride the reader

When transferring the files to an external hard drive, two of its drives suddenly became empty, as in the image below.

Drive: I and j

and once we have chosen to go up, an error suddenly appears as below.

Any help would be very appreciated.

5th dnd – What is the volume of a suspended cauldron?

DMG p. 255 provides the statistics for the headquarters equipment and lists the cauldrons suspended between them:

A cauldron is an iron pot suspended so that it can easily rock and spill its contents. Once empty, a cauldron must be refilled – and its contents generally heated – before it can be reused. It takes three actions to fill a cauldron and an action to reverse it.

The cauldrons can be filled with other liquids, such as acidic or green sludge, with different effects.

Boiling oil. The cauld pours boiling oil on a surface of 10 square feet just below. Any creature in the area must make a dexterity save roll of 15 percent, dealing 10 fire damage per 3 if the save failed, or half the amount of damage dealt if successful. .

I'm trying to determine the number of acid vials (a flask contains 1 quart) to fill this seat motor. It is mainly a measure of cost and if it would change the damage. If so, how could it be?

forms – How can I allow the user to select a quantity of product in volume or quantity?

I am working on a mobile application. It's like ordering an app for the grocery store but wholesale and not at the retailer. So the order is not in 1 quantity, it is in 10000 kg.

Scenario – I am logged in as a user, I will see all lists of all products. I click on add products, then I will see appear to add the quantity of the product. Now this is the hardest part. For wholesalers, we set the minimum quantity for each product (30 kg, for example), but the user may want to add the unit (120 kg) and not in the form of packs (4 packs).

  1. Quantity as text box – The user can enter any number and does not fit in the range (the minimum quantity is equal to 30 kg, then if the user enters 100 kg but We can not accept 100kg.The user must enter 90kg or 120kg

enter the description of the image here

  1. Quantity as drop-down list – The combo range will be huge, as this could have 1 package or 30 kg to 1000 or 30000 kg.
    enter the description of the image here

  2. If we keep textbox for a certain number of packages, the user must calculate that a correct user has 1000 kg, he must order 34 packages.
    enter the description of the image here

  3. Both, but when I enter a value, the second value will be calculated and displayed to the user. Two text boxes for a field is also a bit confusing.

Need suggestion for this.

Functional Analysis – How to calculate the volume of a parallelepiped in a normed space?

Let $ E $ to be a true normed space, and let $ v_1, …, v_n in E $ to be linearly independent. The parallelepiped defined by these vectors is $ P = { sum_ {i = 1} ^ {n} alpha_i v_i | ~ 0 the alpha_i the 1 } $. Since $ E $ is a metric space, we can define the $ n $three-dimensional Hausdorff $ mu_n $ above.

Is there a method to calculate $ mu_n (P) $ if we know "everything" about $ v_1, …, $ v_n and $ E $?

If the standard of $ E $ is induced by an internal product, the volume can be calculated by taking the square root of the Gram matrix of $ v_1, …, $ v_n. I hope that there is something of the kind if $ E $ is a concrete space of functions or sequences. Since $ (i, j) $ the entrance to the Gram matrix is $= frac {1} {2} left ( | v_i + v_j | ^ 2- | v_i | ^ 2- | v_j | ^ 2 right) $maybe we can have $ mu_n (P) $ distances inside the parallelepiped (we also think of the Kelley-Menger determinant).

Note. If we identify $ mathbb {R} ^ n $ with $ span (v_1, …, v_n) $ via a linear isomorphism, the removal of $ mu_ {n} $ will be an invariant measure, and therefore a multiple of the usual measure of Lebesgue. The only thing unknown is the constant factor.

pr.probability – Volume of $ n $ -sphere contained in $ ell_1 $ ball

For a given $ r> $ 1, what is the surface of $ mathbb S ^ {n-1} $ (the sphere of radius 1 in $ mathbb R ^ n $) which is contained outside the $ ell_1 $ radius ball $ r $? Or equivalent, if $ X sim U ( mathbb S ^ {n-1}) $, a point sampled uniformly in the sphere, what is the probability that $ Green X Green_1 geq r $?

This is easy to calculate for $ r geq sqrt {n-1} $, as the area is exactly $ 2 ^ n $ spherical caps, and this has a clean formula, closed form. For smaller values ​​of $ r $However, these hats cross each other and algebra worsens.

The exact value of this probability matters less than the approximate asymptotic limits for $ n $ great.

nginx – Access denied permission to volume in docker-dial

I have followed this tutorial to deploy a web application with the help of django, gunicorn, nginx and postgresql.

When you use the empty application in the tutorial, everything seems to go for the better, but then I tried to recreate the same configuration with the help of my Django application and I got a "denied permission" when trying to collect static files.

The yml configuration is:

version: 3.7 & # 39;

image: postgres: 11.2-alpine
- database: / var / lib / postgresql / data
env_file: .env.pg

to build: .
command: gunicorn mysite.wsgi: application --bind
- static: / usr / src / django / static
- 8000
env_file: .env
depend on:
- postgres

build: ./nginx
- static: / usr / src / django / static
- 8009: 80
depend on:
- Django


The error I get when I run docker-compose django exec python manage.py collectstatic --clear --noinput is

Traceback (last most recent call):
File "manage.py", line 15, in

to enter os.scandir (path):
PermissionError: [Errno 13] Permission denied: & usr / src / django / static & # 39;

I've tried to run a shell inside the container: the "static" directory is where it's supposed to be, but I can not write anything to it (even in as root).
The volume of the database in the postgres container seems to work well. So I think the problem is related to volume sharing between 2 containers.

An idea?
