How/when is calculus used in Computer Science?

Many computer science programs require two or three calculus classes.

I’m wondering, how and when is calculus used in computer science? The CS content of a degree in computer science tends to focus on algorithms, operating systems, data structures, artificial intelligence, software engineering, etc. Are there times when Calculus is useful in these or other areas of Computer Science?

Can and Should Apache Syncope be Installed and Used without Maven / or a better IAM alternative [on hold]

I’m running Ubuntu 18.04 server on a linode. I need an IAM Solution that will play nice with the other tools I intend to use (namely Vagrant, Jenkins [NOT Maven], and Ansible). I’m asking a compound question:

[a]: Is Syncope really dependent on Maven or am I missing something?
[b]: Is Syncope the best solution for my use case (shown below), and ..
[c]: Asking for suggestions what would be a better alternative (if there is one).

My site is to have primary domain landing page (publicly accessible) and several subdomains –where each subdomain requires authentication. I’m not talking about using apache built in password protection I’m looking for a robust, powerful, production grade solution like one might find in enterprise.

I can’t seem to find much information (other than 2 Apache sources) that talk about installing Syncope at all. Both talk about installing Maven like it isn’t an option. I even attempted to find a way to install from source thinking that might lead to a Maven free Syncope install.

This Link: Shows Maven as a dependency.

Is this really the case or is Apache just aggressively pushing it’s products by bundling them?

If it is either impossible or or just stupid to try to use Syncope without Maven then can someone suggest alternatives that might fit my needs?

Can Goodberry be used to summon watermelons?

The description of the Goodberry spell states:

Up to ten berries appear in your hand and are infused with magic for the duration. A creature can use its action to eat one berry.

According to the Wikipedia article on Watermelons:

It is grown for its edible fruit, also known as a watermelon, which is a special kind of berry botanically called a pepo.

Emphasis mine. Given these two bits of information, can the Goodberry spell be used to summon ten watermelons, which can then each be eaten as a standard action?

Can Goodberry be used on horses?

In my compaign my friend Cleric started leveling up in Ranger class. He reached 2nd level now thus he learned two Ranger spells and one of them is Goodberry.

This spell states:

Up to ten berries appear in your hand and are infused with magic for the Duration.


Eating a berry restores 1 hit point, and the berry provides enough nourishment to sustain a creature for one day.

Since he got this spell, food was never our problem anymore. He also has the Create and destroy water spell. There is no need now to buy rations and carry waterskins. But he also likes to ride mounts. And one day ration for a common horse weights 10 pounds. Adventures that take several days are impossible due to this problem. He always needs to carry a cart with him for that horse food and it just makes evrybody slower.

So can the Goodberry spell work on other creatures, like horses?

Can Quicken Spell be used spontaneously if Rapid Metamagic is used?

The Quicken Spell feat carries this special requirement:

This feat can’t be applied to any spell cast spontaneously (including sorcerer spells, bard spells, and cleric or druid spells cast spontaneously), since applying a metamagic feat to a spontaneously cast spell automatically increases the casting time to a full-round action.

This is in reference to this rule in the Metamagic SRD:

Therefore, such a character must also take more time to cast a metamagic spell (one enhanced by a metamagic feat) than he does to cast a regular spell. If the spell’s normal casting time is 1 standard action, casting a metamagic version is a full-round action for a sorcerer or bard.

However Rapid Metamagic specifically supersedes this rule:

When you apply a metamagic feat to a spontaneously cast spell, the spell takes only its normal casting time.


Can Quicken Spell be used spontaneously if the casting time is reduced by Rapid Metamagic?

The way I read it, Quicken Spell‘s special is more of an answer to a logistical question, rather than an explicit prohibition, given that it sites another effect(the spontaneous spell’s increased casting time)as the reason for disallowing it. I see it similar to if the PHB said, “You can’t wield three weapons since all playable races have only have two hands.” If you somehow gained a third hand, the rule would cease to apply.

When was the phrase “Always bet on JavaScript” first used?

The phrase “Always bet on JS” / “Always bet on JavaScript” goes as far back (at least) to a presentation by Brendan Eich at CapitolJS on September 18, 2011.

Are there any sources that confirm that this is when the phrase was coined?

It seems quite original in this context because it includes a reference to the famous line by Wesley Snipes “Always bet on black” from the 1992 film Passenger 57.
