Tempera Paints for Making Washes?

So, I do a lot of hobby crafting for tabletop gaming that involves painting miniatures and building scenery (think model railroad hobbyists). In this craft, there is a lot of need for washes of different sorts that fill in crevices and crannies for developing shadowing and texture. I have some tempera paints that were gifted to me, but I don’t have much of a use for them and was thinking I could make them into washes of different colors since they are already very thin. Has anyone tried tempera paints for this? Will the paint hold up if painted over with acrylics? Will they be washed away when I attempt to seal my work (usually with Mod Podge and/or polycrylic)? I suppose I can experiment a little bit, but I thought I’d see if anyone else has attempted this before putting time into it.

Thanks!

If you’re unconscious and making death saving throws, and an attack from within 5 feet of you hits you, does it cause 2 failed death saves?

In the PHB, it says that three death saving throw failures means you die; taking any damage causes 1 failure, and a critical hit causes 2 failures. But the unconscious condition says that attacks against an unconscious character have advantage and auto-crit if they’re within 5 feet.

That seems really tough — it almost guarantees that you’ll die if hit twice if one is melee, and on top of that if you’re hit once and not stabilized on your next turn you have a 45% chance of getting your third failure from the saving throw.

Am I correctly reading the rules? If you’re unconscious and making death saving throws, and an attack from within 5 feet of you hits you, does it cause 2 failed death saves?

Making S3 objects viewable only for logged in users

As a service provider, I allow logged in users to upload documents to a web server, and upload it to S3. The logged in user should subsequently be able to view his own documents, and I want to serve it directly from S3, with some token-based authentication per request.

I thought that this was a pretty simple and standard use case for S3, but I am unable to find a standard way to this.

Does S3 effectively support per request authentication at object level, and what is the "correct" or "standard" way to do this.

I have read some documentation for STS, but am not able to find a clear way to solve this.

Pre signed urls almost works; the only difficulty is that that it seems to only work with a pre-set expiration time, and "logout" is not supported.

How one would go about making their own YouTube video recommendation engine? [closed]

I’m looking into the possibility of creating a website that would serve as an alternative to YouTube’s video recommendations, attempting to recreate the old experience of getting lost in YouTube before the algorithm drastically changed and became what it is today.

What are the hurdles that one has to go through when building such a project? How would one pull the necessary information to use? What is the common approach when building recommendation engines? Is it even allowed by Google?

Self-research was already done, yet no sufficient answers were found.

I feel like my DMing skills are making the game less enjoyable

I’m DMing a party of five, a rogue, cleric, wizard, fighter, and a ranger that comes every other week. Everything goes well for the first hour and a half, but then after that I can tell my narrations and stuff gets really bad. It’s the difference between ‘you shoot your bow, but your arrow had warped after that last river and you barely miss the knight’ and ‘you miss’. Since we play for about three hours a session and don’t come back together until the next week, the campaign always seems to end in a very bland spot, and sometimes the players have severely misinterpreted the surroundings(honestly, I don’t blame them when my descriptions turn into ‘you exit the building’). Another thing I can tell is that after while DMing, I get tired and my responses to the players get slower and slower and I have to consult the books more often. If it’s been a long day, sometimes I take fifteen minutes getting back to where we were and starting up again, and fall into the bland descriptions pretty quickly.

The players say they don’t mind much, but I feel bad for them since there is another group a table away whenever we’re playing, and the DM there is better than I am. I do give them a decent amount of loot and the occasional magic item and everything is balanced in the campaign. Still, I want to try and change my bad DMing so the campaign is less…wavy(if that makes any sense) in terms of detail. I’ve played with some rather bad DMs before, and know that it’s not fun when there’s little or no color to the adventure. I keep the action going though, plenty of mysteries and combat encounters, but again, it gets bland quickly.

Summary- Campaign is fine(mechanically), but I as DM get boring by the middle of the session and then everything slows down.

So I guess what I’m looking for a way to try and keep myself from getting boring by the end of the session and a way to keep the campaign going smoothly. Any suggestions?

Protect password from apache user by making file executable-only

I (will) have a binary executable file. It’s only permission is user-execute. It cannot be read by user, group, or world. The owner of the file is the Apache user. I don’t want the apache user to be able to read the file, but I do want the apache user (via a PHP script) to be able to execute the file.

The binary executable file contains a password that is used to decrypt an SSH private key file, as I need the public key to hash the request body & compare against a hashed signature my server is receiving. The executable binary file will receive the request body & hashed signature, do its stuff, and simply return "yes" or "no" to indicate if the request is valid.

I know my executable binary file could still be accessed by root or sudo. Preventing that would be interesting, but is beyond the scope of my question.

Would this be an effective way to protect the password (which is in the binary file that can ONLY be executed) against PHP scripts running under the apache user?

Note: I would like to open-source this setup so want it to be useable on a variety of linux servers. I’m personally on a shared-server so can’t really configure apache or the system, and that would be my target audience.

Can the third benefit of the Mobile feat prevent multiple creatures you attack in a single turn from making opportunity attacks against you that turn?

I am playing a monk. I wanted to use the Mobile feat, specifically the third option that prevents opportunity attacks, to do the following:

  1. hit creature 1 with my attack, then move away from creature 1
  2. then use Flurry of Blows on creature 2, then move away
  3. then make an unarmed strike on creature 3

…all without provoking opportunity attacks from any of them, thanks to the Mobile feat.

However, I was told that I can not do that because it only works for one creature and only my action is a "melee attack" or some such reason.

Is my interpretation right according to "rules as written", or am I misunderstanding how it works? It seems quite vague.

Making an D&D 5e Evasion-esque power

In Mutants and Masterminds, much like in many versions of D&D, Area of Attack abilities allow you a dodge check to take half effect. That’s all fine and dandy, but I’m trying to create a character who can see the tiniest movement in his opponents and moves in advance to make certain he’s not where the attack is going to be when it goes off, which results in a very high dodge / parry and a very low toughness.

This works fine for single target attacks, but for AoE attacks, even when he makes his save, he’s still looking at an injury, which doesn’t really work for the idea of fighting-by-avoidance.

I’m trying to make a power that works similar to evasion in 5e, which reads:

When you are subjected to an effect that allows you to make a Dexterity saving throw to take only half damage, you instead take no damage if you succeed on the saving throw, and only half damage if you fail.

I don’t care about the half damage when you fail part, if he gets hit, he gets hit hard, but I want to figure out a way to avoid taking half effect if I succeed the dodge.

It seems, however, that MnM doesn’t really have this option. I’ve looked at immunity (which lacks an AoE immunity), and doing something like a Leaping Reaction on Dodge to physically move out of the way, but I might be over-complicating things.

Making Race Traits independent of race

I’m preparing my new campaign for my group of players and I was wondering if a ruling would unbalance the table.

What will be the effects, balancing-wise, if I let players choose a race for the traits, and another race for the cosmetic appareance of their PCs ?

For example, they could have a PC that is human, but has all the traits of a gnome, in order to make a good wizard. I feel it would enhance RP, since they will be much more confortable with their character. Most of them are experienced players, while others are kinda new, so I unsured if it will unbalance them too much (since the experienced players like to min/max their characters).
