If a thrown weapon has only normal range, does it have unlimited range? [duplicate]

As i was reading the Soulknife Rogue feature "Psychic Blades" from Tasha’s Cauldron of Everything:

…This magic blade is a simple melee weapon with the finesse and thrown properties. It has a normal range of 60 feet and no long range, and on a hit, it deals psychic damage equal to 1d6 plus the ability modifier you used for the attack roll. The blade vanishes immediately after it hits or misses its target, and it leaves no mark on its target if it deals damage.

Following that, i look at the PHB for the rules on range for weapons:

A weapon that can be used to make a ranged attack has a range shown in parentheses after the ammunition or thrown property. The range lists two numbers. The first is the weapon’s normal range in feet, and the second indicates the weapon’s long range. When attacking a target beyond normal range, you have disadvantage on the attack roll. You can’t attack a target beyond the weapon’s long range.

So, the psychic blades from the Soulknife have unlimited range but with disadvantage or only can attack on the normal range?

Plotting a normal curve over a histogram

I am teaching a basic introduction to normal curves, and the textbook introduces the topic with the idea of rolling five dice and recording the sum. Do this many times and create a histogram of the results. (which looks more and more like the normal curve as the number of trials increases) My "code" to simulate this for 10000 rolls is below.

rolls = Table[Table[RandomChoice[Range[6]], {5}], {10000}]; sums = Total /@ rolls; Histogram[sums, {0.5, 31.5, 1}] 

I am way out of my depth here, but wondered if anyone could help with how to plot the "perfect" normal curve that would match the histogram?

I have the following to plot a normal curve, but for it to match the dice example, I need the mean and standard deviation, and how no idea what that would be.

Plot[PDF[NormalDistribution[0, 1], x], {x, -3, 3}, Ticks -> None,   Axes -> None] 

Any help is appreciated.

Would a polymorphed undead retain any diseases when it reverts back to normal form

Specifically, if I cast a heightened polymorph a lich, turning it into a sheep or caterpillar or something then cast contagion on it (5th level cleric spell that gives the target a disease of the casters choosing after it fails 3 CON saves) then revert it back to lich via damage, would it still carry the disease?

What happens to a troll that is perfectly vertically bisected by a normal weapon?

The title pretty much covers it. For reference, see http://www.d20srd.org/srd/monsters/troll.htm and http://www.d20srd.org/srd/specialAbilities.htm#regeneration

There is, of course, no definitive answer in the rulebooks on this. However if you know of some relevant ruling by the game developers that has been published, that would be useful. I’m also interested to hear your personal interpretations.

Does Devil’s Sight allow you to see in darkness as though it was normal light?

There are technically answers to this question both here, Sage Advice, a tweet by Jeremy Crawford, and this question here, but they still seem rather vague/non-descriptive enough.

Devil’s Sight (PHB Pg. 110)

You can see normally in darkness, both magical and nonmagical, to a distance of 120 feet.

But does "see normally" imply you see as though everything is naturally lit up by the sun; lit by a dim torch; still dark, but you can pick out clear images, shapes, and details; or something else entirely?

Can a chain shirt be concealed under normal clothing?

Since the mithral versions of a chain shirt and a breastplate (see Mithral Armor in the DMG) specify they can be worn under normal clothes, I had initially presumed this to be a feature unique to these magic items. However, upon reading the description for a chain shirt:

Made of interlocking metal rings, a chain shirt is worn between layers of clothing or leather. This armor offers modest protection to the wearer’s upper body and allows the sound of the rings rubbing against one another to be muffled by outer layers.

It seems to suggest that a normal chain shirt can also be worn underneath other layers, but doesn’t specify ‘normal clothes’ like the mithral chain shirt does. Can a mundane chain shirt be concealed under light clothes like a shirt?

Does commit after a normal select can call any fsync or flush operations?

Coms counts taken at particular time for all 3 (insert,update,commit).

Com_inserts are in 1.1K  Com_updates are in 1.6k  Com_commit are in  10K 

When enabling general log, I could see after each selects there is a commit. Would this unnecessary commit can cause any fsync or any flush opertation to the server?
