What is a make sense (meaningful) example of language that an unrestricted grammar could generate?

I have learned that:

  1. Unrestricted grammar is used to define (or describe) a formal language.
  2. Unrestricted grammar is used to define recursively enumerable set [https://en.wikipedia.org/wiki/Recursively_enumerable_set][1].

I’d like to find a meaningful example for #1 case which is similar to below context sensitives grammar example to learn the purpose of unrestricted grammar. I could find a meaningful example for context sensitives grammar but I could not find a one for the unrestricted grammar yet. Could you help me?

Language for “Network racing game record” with below record instances:

Mr. Bean Male Player 1

Could I have handled this PC interaction better?

I started up a play by post game on roll20 for a group of friends. A co-worker, and friend of another player, had asked to join in. Let’s call him P1, or Player 1. I said sure, we got the game going after some slow start up.

The party is meeting for the first time in a tavern. They get the adventure hook and agree to work together. P1 is playing a gnome wizard. My wife is playing a human paladin. She thought it would be funny, since her paladin isn’t the brightest of the bunch, to pick up the gnome and get them on the road. P1 responds by wanting to not be picked up. I ask both for a strength roll. P1 loses. So I ask him what his response is to being picked up. His response was to quit and leave our discord server we were using for ooc talk.

While I don’t miss someone who would bail so quickly, I do wonder if I could have done something better. I’d like to learn from this to avoid such a situation in the future. Should I have stopped my wife before she even tried to pick up P1? Was it wrong to let the dice decide who won the conflict of being picked up?

Could this magic item help Ezmerelda in Curse of Strahd?

In the Curse of Strand adventure, the following information is provided about the NPC Ezmerelda in Appendix D (p. 231):

There’s also this magic item that can be found in the village of Krezk (p. 148):

The sunray lasts for 1 minute. If the characters smash the gravestone without placing Tasha Petrovna’s holy symbol in it first, they find nothing within its remains. The ring is a ring of regeneration.

The description of this magic item in the DMG says (p. 191):

So the question is:

Could a mouse kill a bear?

I’m planning for a Mouse Guard game that will culminate in the players facing down a bear!

The rules cover such scenarios far too briefly, only stating that you would need 20,000 mice to do so (via the War skill). This seems like far too few mice to wage war on a bear, also how would this even be done? Are the mice laying siege to the bear, or are they marching on it? Do you even use War? Could a single mouse climb the bear, insert itself into the ear, and assassinate the bear?

I realise that this is a task for the players to decide on but I want to prepare for the circumstances.

How do you kill a bear with mice? (and how can I prepare for this?)

What existing materials could be precedence for The Great Wheel of Eurovision?

Eurovision has been around since 1956 and DnD just a little bit less.

What existing materials could be used as precedence for an EPIC annual contest between bards, where each of the Outer planes in the Great Wheel Cosmology puts forward one performing representative (a talented bard), an Over The Top contest occurs, and delegates from all planes vote on the winner?

Part of what this would entail a contest between bards. Are there existing modules or campaign references that have a contest between bards, including ways to adjudicate besides "roll a skill check"?

The GM has access to both the Pathfinder reference "The Great Beyond" and the 3.5e "Manual of the Planes." The Great Wheel Cosmology would be preferred over the Pathfinder planar treatment: what existing "outer plane" materials in either system would be of use here?

Asking for a friend, whose Players though it would be fun to create a party that is a band (all the PCs are musicians, not all are bards) and the GM wants to punish them. This question also partially inspired by the recent movie Eurovision Song Contest: the story of Fire Saga.

This group primarily plays Pathfinder 1e but other material could be tweaked/twisted/ squeezed into shape.

Could presence of the string “_CONSOLE” in multiple files indicate a hack?

I run a combination of Linux & Windows machines with Dropbox.

Many "selective sync conflicts" occurred, for unknown reasons. Meaning two copies of the same folder appear on dropbox – each copy should be identical.

I will pick one example folder: a music album, folder contains 12 .mp3 files, and a number of .jpg’s.

All files are the exact same file size between the two copies, butdiff clearly shows the contents are different.

Running linux strings on the newer version, every file contains the string _CONSOLE, and the majority of the file has been zero’d out, i.e the data is gone.

Uploading the file’s to virustotal.com for a scan yields a completely clean scan.

Question: is this likely to be malicious? What does the string "_CONSOLE" indicate? Can anyone advise if it is common string for a windows or linux executables?

How long could a dragon survive if it were trapped in its lair?

Pretty much just what the title says. Would it just starve and die over time, or would it be able to survive in some way?

Some clarifications:
I’m assuming a red dragon, and the lair being something in line with the description in the MM: "Red dragons lair in high mountains or hills … Caves with volcanic or geothermal activity…"

So something in line with this, a cave in some high mountains.

For this case, I am assuming the standard rules (not the spellcasting variant).

Is Booming Blade that unbalanced? How could it be rebalanced?

Up until now, we had quite the terrible party lineup (a Rogue, two Paladins and a Barbarian; we soon discovered the game is simply not enjoyable without casters), and we all decided to fix this by designing a new party together: our next lineup will consist of the same Rogue and the Barbarian, but the Paladins (one of which was me) will be replaced by a Divination Wizard and an unholyly multiclassed Bard. Since the Wizard and the Rogue are quite squishy, we decided I should take the role of a frontliner, so I designed the character to be at least kind of an off-tank.

Long story short, I built my character based around a sword and board build with the Ruby of the War Mage and the War Caster feat. Flavour-wise, this character was designed to be both air-headed and hot-headed (hot-air-balloon-headed, if you will), and as such is prone to engage in melee combat if only to feel the thrill of the fight. Since I will only pick three levels of Warlock (the Pact of the Tome is integral to the flavour of my character concept), I won’t be able to access the Pact of the Blade’s Extra Attack invocation. Thus, I based the character’s melee DPR output around Booming Blade and Green Flame Blade.

I discussed with my GM the possibility of being able to trigger Booming Blade via Command, and he said it was not possible, which is reasonable. However, he started looking into the cantrip itself and some (hastily) made damage comparison tables, and said it is broken and should be nerfed to avoid overshadowing the martial characters. Some of the proposed nerfs were:

  • Blade cantrips are now a level 1 spell.
  • Blade cantrips don’t trigger the primary effect, only the secondary one (that is, BB’s movement damage and GFB’s "cleaving" damage)
  • Blade cantrips don’t trigger the primary effect, but the secondary one is increased by one die size (BB’s movement and GFB’s "cleaving" would use d12)
  • Reduced dice size for the cantrip’s damage (for example, d8 to d6).
  • Reduced dice size for the cantrip’s primary effect, but augmented for the secondary effect (d8 to d12)

Needless to say, I’m kinda bummed by this change since the whole gish appeal of this character concept was based around being able to use these cantrips, since playing a melee character with a single attack, only 1d6 at Sneak Attack and the very limited magic items we have would suck hard; I would feel stupid using a single attack when I could be spamming Eldritch Blast instead. The secondary effects of these cantrips are extremely situational and I am sure they won’t come up many times since we often face intelligent enemies. I would be kinda okay with the last proposal, but still, I’m not convinced. I proposed the DM to write some homebrew (I consider myself fairly good at balancing) martial weapons and mechanics to make martials more flexible instead of outright nerfing the cantrip, but he said he wants this campaign to be as vanilla as possible.

How can I convince my DM that the Blade cantrips aren’t that unbalanced? Alternatively, what’s a reasonable way to rebalance them?

Does a Chromecast could be compromised from its default open network?

I left my apartment for few days, so I disconnected my wireless router but I forgot to disconnect my Chromecast as well. I remember that when a Chromecast can’t find the network it was connected anymore, it creates an open network that can be used to reconnect to another wireless network.

The issue is that I’m away from my apartment for a few days and my Chromecast is probably currently broadcasting an open network that anyone can connect to.

Even if there is no internet connexion on that open network, there are two things I’m worried about.

  1. The Chromecast could be attacked from a wireless exploit. We don’t know how someone else’s computer could be infected by malware, the Chromecast could be attacked once that infected computer connects to it (for example, by running wireless exploits against). Even, the worst scenario could be an attacker just connecting to that Chromecast open network and directly run exploits against it.

  2. It might be possible for someone who can attack the Chromecast to get the wireless network password that the Chromecast was previously connected to. This password might be obviously stored somewhere on the Chromecast memory and with some access to the filesystem by a kind of jailbreak (for example, the point 1), it could be retrieved and used to connect to my wireless network.

Considering those two points, should I factory reset my Chromecast once I’m back to my apartment ? Or even safer, should I get rid of this Chromecast considering that the firmware could have been compromised and buy a new one ?
