authentication – Oauth2: should I increase the refresh token expiring date?

I want my clients to be able to schedule a purchase for a given date. When they perform this scheduling action, they are authenticated with an oauth2 token. However the date could be so far from now that the token might have expired when the purchase is triggered. I need to check the user identity and whether they still can perform the purchase when it is triggered, not when it is scheduled.

What would be the best practice to be able to perform this scheduling action ? Should I increase the refresh token expiring date, so that the token can be refreshed before performing the check, when it is triggered ? I have seen other people do this (ex: here), but I don’t know if it is a best practice to increase to, say, 2 years, if I want my clients to be able to schedule a purchase for 2 years.


Sudden increase of links


From August 2020, my website has a sudden increase in the number of targeted domains (was 300 domains and about 2,500 links). Now there are 5,400 domains and 38,000 links. What worries me the most is that these are links from Chinese sites. These are not comments, but links in the footers.



Is Google ignoring these links or should I disavow them?


How to increase a number of daily links and LPM with global site lists?

i have a question.
Is there any way to increase a number of daily links that GSA SER creates from global site lists? I use lists from and they are great. But usually i have only about 200-300 verified links per day and LPM is 0,81. I do not set any limits on daily links in settings:
All filtering options are unchecked:
I connected dropbox folders to GSA SER:
Identified – Contextual_URLs
Submitted – Top_Tier_URLs
Failed – Verified_URLs
Checked Identified, Submitted and Failed and Use URLs from global site lists if enabled:
I run GSA SER on Windows VPS with 4 core and 8 GB RAM at 40 threads with rotating dedicated proxies from (40 threads proxy package), 1 catcha-ll e-mail from and Xevil for captcha recognition.
For some reason GSA SER runs mostly at 7-10 threads instead of 40 in settings:
CPU and RAM are not higher than 50%.
I decided to check how it will change the situation and directly uploaded target URLs into the project (Import target URLs – From site lists – Identified, Submitted and Failed). GSA speeds up to 40 threads, LPM is still low:
In total its a big number of targeted URLs (713K URLs), but i still have about 200-300 daily links from uploading targeted URLs.
Sometimes i see message “No targets to post to (no search engines chosen, no url extraction chosen, no scheduled posting)” in my projects:
At the same time dropbox folders with site lists are updating every few hours.
If i click “Show URls – Show remaining target URLs”, it usually shows 0 URLs, or 8-10 URLs.
Is it possible to solve this problem? Am i doing something wrong?
Thank you!

dnd 5e – How do I explain to an AD&D player that items that increase Armor Class in D&D 5e are overpowered?

+2 AC is much more than an 8% improvement, in one case it is as high as 200%.

Erik’s and Quadratic Wizard’s answers do a fine job of comparing the proposed item to existing magical items in the DMG. The trouble is, if I only believe it is an 8% improvement in AC, I’m going to conclude that the DMG is wrong about how strong +2 AC is. So it seems good and necessary to actually correct the notion that +2 AC is only an 8% improvement.

Sure, the number increases from 21 to 23, which is an improvement somewhere between 8-10%. But that is not how we measure the effectiveness of AC or how much it improves when we increase it.

I have constructed the following table. Column 1 shows that hit bonus of the attacking creature. Columns 2 and 3 show the probability of that creature hitting ACs 21 and 23, respectively. Column 4 shows the percentage of attacks that would hit AC 21, but miss AC 23. Finally, column 5 shows the percentage improvement in survivability of the change in AC. Column 5 is how we determine the marginal effectiveness of a change in armor class.

enter image description here

As you can see, even against the mighty Tarrasque (+19 to hit), the improvement is still better than 8%, sitting around 12%. But we aren’t fighting a Tarrasque at level 6. As mentioned in your question, we’re looking more in the range of +4 to +6 to hit, which gives +2 AC an improvement between 50% and 100%, which is quite significant. 50% of +4 to hit attacks that would have hit me before now miss me. In terms of survivability, this doubles my durability. Increasing my AC from 21 to 23 means I can last twice as long (on average) against a creature that has a +4 to hit. That’s a 100% improvement. Not 8%.

How powerful is AC 23 at 6th level?

It’s pretty powerful. As in, most encounters at this level will pose virtually no risk of harm. But let’s try to set up something of an experiment and run some numbers.

Say our paladin with an AC of 23 is out adventuring solo and gets attacked by three blue dragon wyrmlings.

A blue dragon wyrmling has +5 to hit and deals 1d6+1d10+3 (average 12) damage on a hit. Consulting our table, the blue dragon wyrmling has a 15% chance to hit our paladin with an AC 23. Thus, the average damage sustained by our paladin each round is:

$$3 times 0.15 times 12=5.4$$

A 16 CON paladin taking the average increase for hit points each level will have a modest 58 hit points, which means our paladin can be expected to last for 10 rounds before dropping in the 11th round, assuming he doesn’t use any healing spells or lay on hands. For simplicity the wymrlings didn’t use their breath weapons at all.

You take this absurdly reliable talent for not getting hit by attacks and spread those attacks out across the party and this paladin will rarely have to polish his armor.

Now, I would be remiss if I did not mention that AC is not the only part of combat survivability. An armor class of 30 will do you no good against spells that damage on failed saving throws. But AC is still a huge part of combat survivability.

I get that this is oversimplified in comparison to actual combat. But I think it demonstrates the point well enough. In my party of 5, our Paladin plays the tank role very well. Most of our combat encounters are 3-5 rounds and we have 1 or 2 per 4 hour session. We are also 6th level, his AC is 19 and I still feel that he almost never gets hit. From experience, 19 is very good. An armor class of 23 is broken.

So what do I do?

This question has some great suggestions for handling this in a way that is engaging and fun for both the DM and the player: I gave a too powerful magic item at too low level for a bad reason, what to do?
This situation is a little bit different than the specific situation detailed there, but the ideas and principles can still apply.
