Is there any difference between original prints and PoD (Print on Demand) source books?

Regarding source books by Onyx Path/White Wolf (for the World of Darkness), is there any difference between original prints and PoD (Print on Demand) source books?

Basically, is there a way to know if a source book is an original print? Are there any differences in paper or print quality? Are there other ways to tell them apart?

what the trustworthy way to verify the integrity of source code?

In some of the organizations, takes the hash value of source code build to maintain the integrity of source code review process.According to reviewer if you change the source code than the hash of that source code is changed. But what about when we zip that source code files than also hash of that source code build is changed.

So, My question is

1) I am not sure this method fulfill the requirement of integrity check ?

2) Is there any alternatives for such kind of integrity check ?

Are the pre-compiled binaries in open source projects safe to use? [duplicate]

It seems that the author of a project can upload arbitrary binary files on the release page, and I don’t see a way to verify that the binary is actually built from the source code without malicious modifications.

Surprisingly after some search, I did not find discussions on this potential issue. Is it that I’ve missed something, or people simply just trust those binaries?

I am signing (HMAC) outgoing webhooks to allow users to verify their source, should I also sign outgoing responses?

To allow api users to verify the authenticity of outgoing webhooks, I am using a similar model to slack:

  • Concatenate timestamp and body, HMAC with pre-shared key, add timestamp and HMAC digest to headers.

  • Recipient does the same, and compares to the digest in the header.

I can either implement this exclusively on outgoing webhooks, or I can implement it as middleware that performs this process on both outgoing webhooks, and responses to requests.

Is doing the latter good practice? A good idea?

What is the correct complexity of All paths from Source to Target DFS solution?

The question: “Given a directed, acyclic graph of N nodes. Find all possible paths from node 0 to node N-1, and return them in any order.”

The DFS solution is described here. https://leetcode.com/articles/all-paths-from-source-to-target/

I feel like the author likely got the time complexity analysis wrong. I would have asked the author themselves, but from the discussion below, they don’t really respond to questions. So, what is the correct time complexity analysis for this problem, and how to derive it?

What counts as a sufficient heat source to survive Amber Temple?

In the Curse of Strahd adventure, the sidebar about Amber Temple’s temperature (p. 181) says:

It specifically mentions “heat sources”, and I was wondering what counts as a heat source for the purposes of not succumbing to the cold of Amber Temple.

Is a torch good enough? Or are we talking more like a campfire (say, the sort that someone might make during a long rest)? I imagine Curse of Strahd itself doesn’t expand much more on this, but there might be some generic rules in the DMG or similar that I haven’t managed to find with regards to temperature?

I ask because there will be at least one party member who won’t have any (relevant) magic items, cold resistance or cold weather gear by the time they enter Amber Temple, and I’d like to know what counts as a heat source so I (as the DM) know when to ask for or waive the need for saving throws vs. exhaustion.


For reference, the “Extreme Cold” (Dungeon Master’s Guide, p. 110) section:

Whenever the temperature is at or below 0 degrees Fahrenheit, a creature exposed to the cold must succeed on a DC 10 Constitution saving throw at the end of each hour or gain one level of exhaustion. Creatures with resistance or immunity to cold damage automatically succeed on the saving throw, as do creatures wearing cold weather gear (thick coats, gloves, and the like) and creatures naturally adapted to cold climates.

Does the Armor of Agathys spell still damage attackers if you have temp HP from another source, such as the Dark One’s Blessing feature? [duplicate]

This question already has an answer here:

  • How does Armor of Agathys interact with getting temporary hit points? 3 answers

Recently, I played a warlock in a 5e one-shot. We were playing at level 7 and I was a Pact of the Blade warlock with the Fiend patron. As a Fiend Warlock, I have a feature called “Dark One’s Blessing”, :

Starting at 1st level, when you reduce a hostile creature to 0 hit points, you gain temporary hit points equal to your Charisma modifier + your warlock level (minimum of 1).

The description of the Armor of Agathys spell reads:

A protective magical force surrounds you, manifesting as a spectral frost that covers you and your gear. You gain 5 temporary hit points for the duration. If a creature hits you with a melee attack while you have these hit points, the creature takes 5 cold damage.

At Higher Levels. When you cast this spell using a spell slot o f 2nd level or higher, both the temporary hit points and the cold damage increase by 5 for each slot level above 1st.

The situation was that there was a pack of ‘minions’ (4th-edition term, I know… but they were low-AC 5 hp monsters that died in 1 hit most of the time) attacking my group. The dragonborn wizard knew Fly, and grabbed the halfling and flew out of reach of the group of minions; I was left there with Armor of Agathys cast on me at level 4, so I had 20 temp hp and did 20 damage to each minion.

The question comes from the functionality of Temp HP (THP)… It does not stack. Instead, you must choose which set to acquire, either keeping the THP you currently have or using the new number provided by whatever is trying to give you more THP.

Once I was below 20 THP from the attacks made on me by this swarm of minions, I started taking the 10 (warlock level + CHA mod= 7+3) THP provided by Dark One’s Blessing. After rereading Armor of Agathys today, I noted it says ‘while you have these hit points’… leading me to believe that choosing to take the 10THP from Dark One’s Blessing would remove the Armor of Agathys and its damaging capability.

TL;DR

Does Armor of Agathys only work if you have THP from the spell specifically, or does it still work if you gain more THP from another source (like from Dark One’s Blessing) while the spell is still active?

fragmentation in ipv4 is done at source or routers or at both

fragmentation in ipv4 is done at source or routers? according to what i read, fragmentation can be avoided at source, by doing segmentation at transport layer wisely to match MTU of source network… we can also avoid fragmentation at routers by using PMTUD(path MTU discovery), where we use ICMP packets with dummy port to determine smallest MTU size required in path from source to destination. Then segmentation done at source to match smallest MTU in the path… so, fragmentation is done at both source or routers as per requirements if we don’t use above methods.. is it correct?
