How do Unchained Eidolon’s type Resistances interact with the Resistance evolution?

Certain Eidolon types obtain energy resistance against some type of damage – for example the Psychopomp type gains cold resistance 10 and electricity resistance 10 at 4th level – while some obtain the Resistance evolution – for example the Angel type obtains the resistance (acid) and resistance (cold) evolutions at creation – but what is not clear to me is this: does the Resistance evolution stack with the first (Psychopomp’s) energy resistance? Or does it stack with nothing? I’m asking because while it’s clear that it’s not meant to stack with itself, it is a little more nebulous with the first case.

Adding constraints in grammar for Grammatical Evolution

I’m trying to use Grammatical Evolution for creating trading strategies. Each sentence in the grammar when evaluated gives a weight matrix of size n x p . (n is the length of backtesting period and p is the total number of stocks in portfolio)

BNF form of Grammar

<expr>  ::= (<foptr>(<expr>,<expr>,<day>))|          (<fopbi>(<expr>,<day>))|          (<fopun>(<expr>))|          (<expr><matbi><expr>)  |         <var> <foptr> ::= corr | covariance <fopbi> ::= mean |                 sma|             ema <fopun> ::= rank| -1* | 1/  <matbi> ::= + | - | * | / <var> ::= Open|High|Low|Close|Volume <day> ::=  5 | 10 | 15 | 20 

The problem is some expressions in this grammar do not make sense. For example, we cannot have a strategy like $ Volume/Volume$ or $ Low-Low$ , etc. And some of the strategies do not have any physical significance, for example, the strategy $ Volume+Close$ is not valid as the units of volume and close are different. Any suggestions/references on how to add these constraints to the grammar or circumventing this issue in genetic algorithms will be helpful.

Evolution of the Rogue in D&D

How and why has the concept of the “rogue” evolved over D&D’s history?

It seems that what the general perception of what people think of with a “rogue” or “thief” has changed drastically over the years. In some eras, they are the sort that is weak – almost defenseless, even – in combat, and do their best to avoid combat while focusing on other elements such as pickpocketing and hiding. In others, they are considered “Combat Strikers” and are actually better at dealing damage than fighters, capable of dealing precision strikes casually in melee, and with their more thief-like skills becoming more of a sidenote (considered “skill-monkey” abilities, as opposed to be their core defining traits). From what I can tell, this seems to be a gradual shift over time.

While this would be nothing special if characters in any system could be customized to be of either style – as is usually claimed by systems – the fact is that most editions of D&D force characters at least partially to one direction over the other. 3rd Edition rogues automatically have Sneak Attack, which is highly damaging, scales well and automatically, and can be triggered merely by flanking (read: ganging up on in normal combat) enemies, cementing them as warrior-rogues. While they can also be, or not be, other types of rogues based on their skill selections (social skills, larceny skills, arcobatic skills), they invariably have strong combat abilities. Pathfinder further enforces this by increasing their hp to d8, something that wouldn’t necessarily fit a rogue that avoids fights and doesn’t know what it means to even take a hit.

4th Edition rogues are flat-out considered called Strikers and are designed as fragile speedsters or glass cannons. Meanwhile, older versions of D&D appear to treat rogues more like the burglar sort, perhaps based off of Bilbo Baggins (as much of D&D was originally based on LotR), who did little stabbing. Furthermore, some different game systems truly do allow for playing different types (Anima: Beyond Fantasy has three different classes primarily based on being a rogue: Shadow (fighty rogue), Assassin (social rogue), and Thief (stealy rogue)). From what I can tell, however, this type of freedom is rare in D&D proper.

Has the cultural perception of rogues changed over the years? What is the timeline of the evolution of the rogue? How has it changed over different games (i.e. old D&D vs modern D&D) and over the years (80s, 90s, 00s, 10s)?

“NSPR headers not found” error while building evolution using cmake

I am installing Evolution from source using cmake by following command:

cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release -DWITH_OPENLDAP=OFF .. 

But it result in following error message:

-- Looking for include files nspr.h, prio.h -- Looking for include files nspr.h, prio.h - not found CMake Error at cmake/modules/FindSMIME.cmake:80 (message):   NSPR headers not found.  Use -DWITH_NSPR_INCLUDES=/path/to/nspr to specify the include dir of NSPR. 

Any one could help me to solve this problem?

NOTE: -DWITH_OPENLDAP=OFF is because cmake gives me an error if I do not use this phrase.

How to automatically obtain keys in Evolution for e-mail recipients? (key discovery)

I am using the PIM Evolution 3.22.6 for e-mail and contacts. For encrypting e-mails gpg (GnuPG 2.1.18) is used by Evolution.

How can I configure my system such as when I compose an e-mail the PGP key for the recipients are automatically retrieved from key servers and added to my keyring?

For example when I try to send an e-mail to a recipient, which is not in my keyring I get the following error message: gpg: <edward-en@fsf.org>: skipped: No public key

In case I run – outside of Evolution – gpg --search-keys edward-en@fsf.org a key is successfully found. Is there any way to tell Evolution to deal with the search?

Evolution layout settings can not be changed

i want to customize my evolution but everytime i make a change, it is completely ignored – it jumps back to default. For example when i uncheck status bar, nothing happens. Also in my gnome-calendar same thing happpens when i want to go to week or year view – it jumps back to month view. I tried to purge everything and install again but it didnt work. Any ideas why does this happens?

Update: when i open those programs in terminal as root there is no problem.

I am using Lubuntu 19.04
