Posting in dead threads? | Forum Promotion

Absolutely! I don’t mind either way, start a new thread or reply to old ones. I’m quite grateful for the quality activity in our forum. I understand that it’s just easier for people to just start a new thread rather than dig for a related topic. On the flip side, I understand that not everyone likes the idea of starting a new thread and would rather post a reply to an existing one. …to each their own.

 

unity – How does Dead By Daylight randomly generate maps every game?

If you don’t know what Dead By Daylight is, it’s a multiplayer 4vs1 survival horror game where the locations of map elements like buildings, interactable objects, etc. change every time. There are only a few limited combinations of these random generations and I would like to know how to go about creating something like this in Unreal Engine/Unity Engine/Lua/Roblox Lua

hard drive – Restoring the partition table and a fsarchiver backup from a dead disk to a new one

My openmediavault server’s ssd disk died, and I replaced it with a new one (different brand, same capacity). Now I wanted to restore my last backup made with fsarchiver via the omv backup plugin, and I’m following this guide. After following the first 13 steps, I’m stuck with the last 2, where the critical things are done.

These were the partitions on my new ssd nvme disk before trying to restore (I had installed OMV on it):

Device         Boot     Start       End   Sectors   Size Id Type
/dev/nvme0n1p1           2048 486395903 486393856 231.9G 83 Linux
/dev/nvme0n1p2      486397950 488396799   1998850   976M  5 Extended
/dev/nvme0n1p5      486397952 488396799   1998848   976M 82 Linux swap / Solaris

After I ran the “restore grub and the partition table” step:

dd if=/mnt/array/Backup/omvbackup/backup-omv-30-ago-2021_03-00-01.grubparts of=/dev/nvme0n1

Now it looks like this:

Device         Boot Start       End   Sectors   Size Id Type
/dev/nvme0n1p1          1 488397167 488397167 232.9G ee GPT

And when I try to restore the main partition:

fsarchiver restfs backup-omv-30-ago-2021_03-00-01.fsa id=0,dest=/dev/nvme0n1p1

I get the following error:

oper_restore.c#152,convert_argv_to_strdicos(): "/dev/nvme0n1p1" is not a valid block device

So I think I messed the partition table. Maybe the grubparts are not written to /dev/nvme0n1 but to other place? Before trying to restore the partition table I could see GRUB installed with:

dd bs=512 count=1 if=/dev/nvme0n1 2>/dev/null | strings

But I can’t see that anymore.

postgresql – View Expansion and Removing “dead variables”

I have a large set of interwoven views in Postgres that sometimes are make inefficient use of other views.

For example,

CREATE VIEW C AS
SELECT A.a, B.b
FROM A
LEFT JOIN B on A.id = B.id

Then,

SELECT C.a, COUNT(*)
FROM C
GROUP BY C.a

It’s more complicated, but the idea is that the second query doesn’t make use of the JOIN from the VIEW. In the EXPLAIN, this is not optimized away by Postgres.

I’m looking for an automated way to “expand” the second query to something like,

SELECT C.a, COUNT(*)
FROM (
  SELECT A.a, B.b
  FROM A
  LEFT JOIN B on A.id = B.id
) C
GROUP BY C.a

So I could then easily see the optimization and make the change my hand.

postgresql – Would you recommend to use PL/R in 2021 or is it dead?

And for many years there exists a PostgreSQL extension to use GNU-R directly in the database: https://www.joeconway.com/plr/

Ubuntu packages are also provided and updated for latest PG: https://ubuntuupdates.org/pm/postgresql-13-plr

But it seems to me, that there is no maintenance happening for the extension itself. (Changelog references PG 9.5) Is it dead?

We would love to use PL/R in our PG-databases, but I am afraid that I will depend on an unmaintaned extension then, which is not ment for productive use and it will kick-back in a few years…

Has anyone used PL/R extension with PG for production in the last years? Was your experience good? Are recent versions of GNU-R supported?

dnd 5e – What is a fair price for a busy cleric to charge for raise dead?

An adventuring party member dies. They seek out the service of a 9th level cleric to raise their dead companion.

The cleric bemoans after their request “but I have many others with such urgent requests and each will expire in time should I not attend to the rituals I’ve already committed!”

How much should the cleric charge the adventurers considering he had prior commitments, a consistent demand for his service?

The cleric has all the usual constraints, he can cast ‘raise dead’ once per day and the limit of the spell is effective only 10 days from a mortal wound. The cleric or the adventurers presumably would have to pay off one of those in line – in order to take their spot.

This is a home game where I want to bring to bear additional practical aspects of procuring spell service (raise dead).

I am looking for existing guidance from the rules regarding spell pricing rather than arbitrary ideas.

dnd 5e – Toll the Dead description (5e)

dnd 5e – What happens when you cast Speak With Dead on a person who used Clone?

As written, speak with dead functions normally.

Speak with dead states:

This spell doesn’t return the creature’s soul to its body, only its animating spirit

So there is no interaction between speak with dead and the creature’s soul, so we shouldn’t expect clone to create a problem for us there. Unfortunately, the phrase “animating spirit” appears once in the entire D&D 5e corpus – in the spell description of speak with dead, so there isn’t much to go on concerning what that really means or the lore behind how the spell works. As written, speak with dead works just fine, as it explicitly does not interact with the creature’s soul.

Further, speak with dead requires only a corpse, not that the creature that the corpse was formerly be dead. So suppose we have the corpse of a creature that has used clone to inhabit a new, properly functioning body. What does speak with dead say?

You grant the semblance of life and intelligence to a corpse of your choice within range, allowing it to answer the questions you pose.

Do we have a corpse? Yes. Next, speak with dead states:

The corpse must still have a mouth and can’t be undead.

Is it undead? No. Does it still have a mouth? We can assume yes, since this isn’t really pertinent to the question. Here are all the requirements for using speak with dead, summarized:

  • a corpse within range
  • has a mouth
  • not undead
  • hasn’t been targeted by speak with dead in the last ten days

A creature’s use of clone does not complicate any of these requirements, so speak with dead works as usual.

encryption – Possible to perform data recovery with dead cpu? (LG G6 – Android 9)

I’ve got a dead LG G6, suddenly freeze during normal using.
After force rebooting, it was completely dead even though connecting to charging cable.

Have already performed cpu chip-off and reballing, still the same symptoms as before.
The cpu (Qualcomm Snapdragon 821) was found dead and the mechanic told the data is non-retrievable because of the fde with cpu.

Research from internet:
- The data partition is encryted with the key stored in cpu
- only replacing normally-function cpu is not possible to power on the device

Im wondering if chip-off technique applied to take off the ufs, reading it using a BGA153 reader on computer + brute-force decryption is possible or not.

The knock code(screen lock) is known, may perform dictionary attack without wild guess.
The screen lock is 6-step knock code.

Steps:

  1. Extracting the full dump as a bin file
  2. Performing a brute-force method(hashcat + physical analyzer) to the mounted storage
  3. Good news or infinite waiting?

Thats absolutely my bad of not frequently backup the phone, want to make up the fault and retrieve those memory back.

Highly appricated to any advice on the issue, many thanks!
