Nested loops join algorithm – additional available page buffers

The basic version of nested llops join algorithm only uses two main memory page buffers for loading the pages.

But if additional page buffers are available the I/O cost can be reduced.

Should I chose to use the additional available page buffers to hold more pages of the relation considered by the outer loop or the inner loop?

And why?

I apologies if this is the wrong place to post this question Thanks in advance,

What spells or magic items are available to detect lies?

I’m playing through Storm King’s Thunder, and came across an unusual magic item:

Gavel of the Venn Rune

The Gift of Truth feature for this item says:

Whenever a creature utters a lie while within the 30-foot-radius sphere, that creature takes 5 psychic damage and flinches visibly.

This is pretty cool, but it makes me wonder:

What spells or magic items are available to detect lies?

What is the difference between available expressions analysis and very busy expressions analysis?

I am having trouble understanding the conceptual meaning of the two kinds of analysis. I know the equations and how to solve the problems and I know how one is a forward data-flow analysis while the other is a backwards data-flow analysis, but there is still something missing in the explanations I have seen so far, in a higher level.

Newbie questions – only 17 threads running of 200 available

Hi!

I’m testing my first GSA SER project, everything seems to works fine except one major problem.
I set up max 200 theads, but GSA runs much more less (for example 10-50 threads at a time with ~50-75 LPM). Sometimes up to 100+ threads with 130+ LPM. All system resources almost free – pls find attached screenshot. I use a premium links list. Speedtest shows about 100-150 Mbs speed. Xevil runs at another machine and have a lot of free resources.
Why cant GSA run maximum amount of threads?

Hope Sven or smb else could help me with it.
Best regards.

Which of the available options for downtime from XGtE would give the most money after one week?

In the "Downtime Revisited" section of Xanathar’s Guide to Everything, pages 123-134, it gives you various suggestions with what to do with a week of downtime. My character is being given a week of downtime and they need to make as much money as they can within this week.

Which of the available options would give the most money after one week?

Some thought/restrictions (although answers can still mention these excluded options alongside the best for my case if they wish):

  • Crime: My character isn’t really built as a rogue, and my DM may well require me to have a relevant background, like Criminal, to qualify for this downtime option, so this one’s out.
  • Gambling: This can go well, or badly (that’s why it’s called gambling), but I don’t have that much money to begin with, so although it’s probably the best option if you have lots to start out with and are happy to risk it (as the amount you can make scales with how much you put down, assuming you win), it wouldn’t really help me much as the risk isn’t worth the reward when I don’t have much to start with.
  • Pit Fighting: Obviously, all PCs can fight, since D&D is a combat-centric game, but I’m not a combative class, I’m a warlock who’s trying to go for more of a "summoner" playstyle, so this probably won’t be my strong suit. Then again, it appears to be "nothing lost, nothing gained" if I lose, so if might be the best one for me, unless the others are better?
  • I was considering just going with the "Work" option, and hoping I roll well enough to get that extra 25gp, but the Pit Fighting option already outpaces that even if I only roll well once out of three times, so I’m guessing that Work isn’t much good after all…

So to clarify: I’m excluding Crime and Gambling as I don’t think they’ll be appropriate, and I’m looking for an option that tops Pit Fighting, which appears to be the best one at a glance for making money quickly.

What does it mean if a domain does not have any WHOIS information available?

For example, I found two websites that mimic my domain name perfectly eg mydomainname.com, with the two offending websites being mydomainname.bw and mydomainname.br. However the domains are not linked to any IP, nor do they have any WHOIS information available. The only way I can see that they are even registered is if I go to a domain seller that deals with .bw and .br TLDs, they tell me that the domain cannot be purchased. Does that mean the domain is just "reserved" somehow and nobody registered it?

Open a portal secured with Arcane Lock – What options are available?

What are the various ways that a portal can be opened when it has been secured by the 2nd level wizard spell Arcane Lock?

The spell itself says only dispel magic and knock can successfully bypass the lock. Are there any other options? For example, does a skilled thief have any chance at unlocking it using open lock? Could a very strong fighter smash the door still?

GnuPG – connecting to specific card reader when multiple reader available

Currently I can use

$   gpg --card-status 

to interact with smartcards that run the OpenPGP applet. Through trial-and-error, it seems that only the first card reader will interact with gpg. Using options that pass to scdaemon seem to be deprecated:

$   gpg --reader-port  1 --card-status gpg: WARNING: "--reader-port" is an obsolete option - it has no effect except on scdaemon 

Is there a way to interact with an OpenPGP smartcard that is not connected to the first card reader?
