active directory – Domain creation: Invalid name format

We are attempting to create a tree domain in our network. When creating the domain we are getting the error listed below. We’ve double checked the naming to make sure it does not include any special characters. If we change the “.edu” to anything else, such as “.local” it progresses without the error, but we really need to use the original domain name. I’ve also listed the powershell script used to run the domain promotion below the error message:

Install-ADDSDomain : Verification of prerequisites for Domain Controller promotion failed. The domain >DNS name “pennco.edu” has an invalid format.
DNS names can contain letters, numbers, and hyphens, but not spaces. Periods are used to separate domain >labels, which can be no longer than 63 bytes. The top-level domain name must contain
at least one non-numeric character.
Characters that are not allowed include: ! ” # $ & ( ) * + , ‘ / : ; < = > ? @ ( ) ^ { | } ~
Example: domain-1.microsoft.com.

btree – Database index creation multiple criterias

Context:

Designing a B-tree database.

I have a table with say 12 columns (A,B,C..). Those columns can be varchar or int in any order (in case of multiple tables).
When running a query any of those columns can be constrained to a value, but not necessarily all.

And I cannot statistically predict which ones will be set. The values in columns are random unpredictable/cause fragmentation.

If the dataset is big enough (multiple gigas and up) to be willing to avoid linear scanning, what would be the best indexing strategy here?

Strategies:

1.should I create a table for each possibilities (in fact creating a composite index per table) and update it on alteration? (carefully updating other related tables as well)

2.should I keep one table but multiple composite indexes, with a null option in the tree to jump to the next tree? (this has my preference)

3.?

Clarifications:

Insert/update are not time constrained. Search has to be as fast as possible.

Again, not interested in sql queries, just your opinion/experience.

Thanks

Character Creation – Open a skill with B1 stat as root

Do not open a skill and leave it at 0.

Exponent 0: If your stat, skill, or attribute is currently exponent 0, you may not be able to test this ability. You may not get help, FoRK, or spend Artha on it. It is not available until you advance, replenish, or restore it.

– "Test your skills", Burning wheel gold P.37

Yes, you can completely disable yourself from observing on your own. Do not do that.

When it comes to character creation, you need to spend multiple skill points.

If you open the skill naturally during the game, at some point during the manufacturing process of the (10 – skill root =) 9 ability tests To open the skill, make sure you try at least one test with a basic difficulty of 1 (before doubling) and one with a basic difficulty of more than 1, since:

If the beginner's luck test would be difficult or challenging for the statistics before doubling, write down a test to advance the statistics.

macos – User creation fails with sysadminctl

I created a user with that sysadminctl and faced some mistakes.
I am using macOS 10.15.3.

To create the user, I did the following:

$ sudo sysadminctl -addUser someuser -fullName "Full User Name" -password - -admin
Password:
2020-05-07 10:56:14.958 sysadminctl(48350:60273463) ----------------------------

2020-05-07 10:58:04.162 sysadminctl(48350:60273463) Creating home directory at /Users/someuser

As a result, there were two problems:

Problem 1. Error -14120 as you can see in the above output.

Problem 2. A strange directory /Users/admin was created:

$ ls -la /Users
total 0
drwxr-xr-x   8 root          admin 256 May  7 10:58 ./
drwxr-xr-x  22 root          admin 704 Feb  6 02:08 ../

drwxr-xr-x+ 17 myaccount     staff 544 May  7  2019 myaccount/

What have I done wrong?

To edit:
/Users/admin/.bash_history contains brew doctor.
Maybe it was used somehow in the past to manage homebrew.
I still don't understand why sysadminctl updated the timestamps and made the new user the owner /Users/admin/. Looks like it's a homebrew craze / bug …

Character Creation – Are there PL2 options that can be implemented in a PL20 setting?

I did a thought experiment with inventing Mutants and masterminds 3e. The way that inventory works is a DC 10 + pp technology check to design something at 1 hour / pp, followed by a DC 10 + pp technology check to design it at 4 hour / pp to create pp. However, pairing it with Quicken will reduce the priority tasks you get in Quicken. This will be a significant blessing once you hit PL 20. If you invest the minimum 51pp required, you can design and create a 30pp invention in less than a second (practically a free promotion), or spend 6 seconds designing and engineering anywhere from 12 up to 25 unique 30pp inventions ( depending on whether you consider DM 30 hours 14th or 15th).

Now that many temporary devices built in such a short time can be devastating under the right circumstances, but I'm more interested in the construct spawning side of the equationBeing able to generate 12-25 independent constructs in one round (or 6-12 if your GM limits you to a standard inventory action) while accessing usable materials is a serious threat. However, both the PL limits of something at 30pp and the arsenal that a PL 20 character has make this a very poorly advised option. I know that it is most likely the most efficient way to make normal inventory-based devices to take advantage of the synergies I suggested. But are there any options that a PL2 construct can properly accept in a PL20 setting?
