Understanding Logging Priority & Options in Oracle DB

From my understanding once we switch on database logging, the entire DB goes into logging mode and generates redo logs.

I want to categorically exclude/include some tables/tablespaces from this logging as they are not required for recovery incase of failures.

Is there any priority on the logging options and to exclude certain tables/tablespaces from logging so as to reduce some of the traffic going to redo logs.

Address finder for website, cheap/budget options for the UK

Hi All,

This is my first post and I have no web design or HTML experience so please excuse the naive nature of this question. I'm building a website with my friend and we require a postcode or address finder for the UK (initially). It's a very common functionality on many different websites but on researching the topic, I was surprised most of the APIs like Postcodes.io, Adressian, getaddress – charge by number of searches made. Now don't get me wrong, they're entitled to charge for these…

Does the Monstrous Combat Options rule of breath weapons scaling with creature size apply to PC’s?

While discussing build options with a fellow party member (an Alchemist), they mentioned a rule granting breath weapons increased area when the user increases size category. After a bit of searching, I was able to find the rule in question:

Breath Weapon: The monster gains a breath weapon that deals 1d6 points of damage + 1d6 per CR. A target can attempt a Reflex saving throw to take half damage. If the breath weapon is a cone, it’s 30 feet long, increasing by 10 feet for each size category above Medium, and decreasing by 5 feet for every size category below Medium. If the breath weapon is a line, its area of effect is twice as long as a cone would be.

However, said rule was located in a section about monster creation/advancement, and now we’re debating whether or not it applies to PC’s changing size due to spells or buffs. Is there any other RAW indication whether or not gaining or losing a size category would generally affect breath weapon areas in this manner, or would this ultimately be a matter of GM fiat?

How to stop Google search, by using “noindex” and “nofollow,” from offering options to private pages on a website

I have a family history website, call it "my_family.com". The primary file, index.php, has some introductory remarks of explanation and an html form into which one puts the website’s password (there’s a single password used by all family members). If one runs "my_family.com" and inserts the correct password and clicks on the "Submit" button, the php code in the file takes you to the first of several html files — call it "first.html," which gives one links to further html files. All of these files contain family trees, copies of letters, photos, reminiscences, obituaries, etc., and none of which should be available to non-family-members. I soon found out found that if one put the phrase "my_family.com" into the Google search window (whether on computer of smartphone), one got a list of options, not just a Login option but about eight to ten 3-4 word excerpts from html files on the website; and if one clicked on any of these latter options, one bypassed the password process and was taken directly to other files on the website, i.e., files that should never be publicly revealed.
What I’ve done to avoid such access is to create a cookie in the original index.php file. If the user inserts the correct password, the cookie is set to "passwordCorrect" Each subsequent html file then checks whether the cookie has that value before the user is allowed to move on Putting in the cookies has solved the problem of public access, but nevertheless a Google search still shows the 3-4 word excerpts. I have tried to stop Google search from doing this by putting into the header section of first.html: ”” (without the outer quotes). But that has been in the file for about three weeks and has proved useless. I tried using Google Search Console to get Google to make an early "crawl" of the file my_family.com, but am frustrated by the lack of examples about how to use it, and don’t think I succeeded. Maybe I should be asking for a crawl of the file my_family.com/first.html, instead of the basic my_family.com website? I’d appreciate any advice anyone has about this. For example, how do I determine when the last crawl was, when can I expect the next crawl, is the meta tag in the correct file, etc? Thanks

How does the Oathbow’s benefit to ranged attacks interact with the Arcane Archer fighter’s Arcane Shot options Piercing/Seeking Arrow?

Part of the description of the oathbow magic item says:

When you make a ranged attack roll with this weapon against your sworn enemy, you have advantage on the roll. In addition, your target gains no benefit from cover, other than total cover, and you suffer no disadvantage due to long range. If the attack hits, your sworn enemy takes an extra 3d6 piercing damage.

However, the Arcane Archer fighter archetype from Xanathar’s Guide to Everything (previously appearing in UA: Revised Subclasses) has the ability to imbue their arrows with magic. Two of the Arcane Shot options seem like they might conflict with the oathbow‘s trigger condition.

The description of Piercing Arrow says, in part (XGtE, p. 29; identical to the version from UA:RS):

[…] When you use this option, you don’t make an attack roll for the attack. Instead, the arrow shoots forward in a line, which is 1 foot wide and 30 feet long, before disappearing. […] Each creature in that line must make a Dexterity saving throw. On a failed save, a creature takes damage as if it were hit by the arrow, plus an extra 1d6 piercing damage. On a successful save, a target takes half as much damage.

The description of Seeking Arrow similarly says (XGtE, p. 30; also identical to the UA:RS version):

[…] When you use this option, you don’t make an attack roll for the attack. Instead, choose one creature you have seen in the past minute. The arrow flies toward that creature, moving around corners if necessary and ignoring three-quarters cover and half cover. If the target is within the weapon’s range and there is a path large enough for the arrow to travel to the target, the target must make a Dexterity saving throw. […] On a failed save, the target takes damage as if it were hit by the arrow, plus an extra 1d6 force damage, and you learn the target’s current location. On a successful save, the target takes half as much damage, and you don’t learn its location.

So how does the oathbow interact with these 2 Arcane Shot options by RAW?

I know some situations override things going both ways in favor of exploitation and prevention.

Does the class skill let you bypass the attack roll while getting the oathbow‘s power buff? Or do you not get the buff?

What are the most tolerable options for a more general public type not to be victimized by malware?

I’ve talked with a new friend who is fairly bright and who can do some interesting things programming Office applications, but whose technical abilities omit infosec. And he got bitten by nasty malware.

I’m wondering what options might be most productive to offer to him. I’m not sure it’s realistic to repel all dedicated assault, but cybercriminals often look for someone who would be an easy kill, and (perhaps showing my ignorance here), I think it could be realistic to make a system that’s hardened enough not to be an easy kill.

Possibilities I’ve thought of include:

  1. Windows 10 with screws turned down (how, if that is possible?).

  2. Mint or another Linux host OS for what can be done under Linux, and a VMware or VirtualBox VM that is used for compatibility and may be restorable if the machine is trashed.

  3. Migrating to a used or new Mac, possibly with a Windows Virtual Machine, but most people using Macs don’t complain they are missing things.

  4. Perhaps with one of the technical situation, point my friend to user education saying things like "Don’t download software that you hadn’t set out to get. The price of Marine Aquarium of $ 20 up front is dwarfed by the hidden price tags of adware and spyware offering a free aquarium screensaver.

This is not an exhaustive list, although it’s what I can think of now. I’ve had a pretty good track record for not engaging malicious software, and I think it can be learned (and that documentation for online safety would be taken very, very seriously).

What can I suggest to my friend for online safety?

Discrepancy between the results of NIntegrate with different methods and options

I am trying to perform a numerical integration on a function defined through a sum of exponential terms. The summation is given by:

sum[z_, z0_, t_, nmax_] :=   1/Sqrt[4 t]*Sum[ Exp[-(z - z0 - 2 n)^2/(4 t)] + Exp[-(z + z0 - 2 n)^2/(4 t) ], {n, -nmax, nmax}]; 

and we define

f[z_, zp_, y_, yp_, z0_, t_] =    ( Exp[-(y - yp)^2/(8t)]/Sqrt[8t] )*D[sum[z, z0, t, 20]*sum[zp, z0, t, 20], t, z, zp]; 

where I have chosen nmax=20.

I wish to perform numerical integration on f. I define

int1[a_] :=   NIntegrate[ f[zp, zpp, 0, ypp, z0, t]*( ypp (zp - zpp) )/( a (zp - zpp)^2 + ypp^2 )^(3/2),  {z0, 0., 1.}, {t, 0., 10.}, {zp, 0., 1.}, {zpp, 0., 1.}, {ypp, 0., Infinity}] 

Based on which I get the following table (no errors generated)

tab1 = Table[{a, int[a]}, {a, 1., 5., .5}]  (* {{1., 0.00135643}, {1.5, 0.000734155}, {2., -0.000611633},  {2.5, 0.0000596739}, {3.,0.0359735}, {3.5, 0.0292143},  {4., 0.01122}, {4.5, 0.00889722}, {5., 0.00649666}} *) 

To check, I tried AccuracyGoal-> 30 and PrecisionGoal -> 30 and got the same results. However, as soon as I include WorkingPrecision, the integrated gives 0 all the time. For example:

intwrk[a_] :=   NIntegrate[ f[zp, zpp, 0, ypp, z0, t]*(ypp (zp - zpp))/(a (zp - zpp)^2 + ypp^2)^(3/2),  {z0, 0, 1}, {t, 0, 10}, {zp, 0, 1}, {zpp, 0, 1}, {ypp, 0, Infinity},  AccuracyGoal -> 30, PrecisionGoal -> 30, WorkingPrecision -> 100] 

Gives all zeros – which I can’t seem to understand. Am I doing something wrong here?

Then I also performed the calculation using LocalAdaptive method:

int2[a_] :=   NIntegrate[ f[zp, zpp, 0, ypp, z0, t]*(ypp (zp - zpp))/(a (zp - zpp)^2 + ypp^2)^(3/2), {z0, 0., 1.}, {t,0., 10.}, {zp, 0, 1}, {zpp, 0., 1.}, {ypp, 0., Infinity }, Method -> "LocalAdaptive"] 

which gives

tab2 = Table[{a, int2[a]}, {a, 1., 5., .5}]  (*  {{1., 1.75934*10^-29}, {1.5, -8.79671*10^-30}, {2., 8.7967*10^-30},  {2.5, -8.7967*10^-30}, {3., 8.7967*10^-30}, {3.5, -2.80635*10^-51},  {4., -8.79671*10^-30}, {4.5, -9.78474*10^-37}, {5., -9.78474*10^-37}} *) 

which is a very different result. This one also runs much faster than the int1. I guess these numbers here are not reliable, but how can I check them?

PS: based on the answer to my previous post, I tried Method -> "GaussKronrodRule" and Method -> {"MultidimensionalRule", "Generators" -> 9}, but they run forever and I couldn’t get any outcome.

Does a non-magical character have any options to fight a swarm without fire?

In a session with a witch, a wizard and me, a rogue with a knife and crossbow, I found my character to be astonishingly useless against swarms. There was a swarm of Hellwasps and I quite literally just hid behind the magic users. The mages were rather absurdly effective (my contribution to the session was nil), and after looking up the general mechanics for swarms, it appears you have three options:

  • Area affect magic (I don’t even have Minor Magic and don’t plan on acquiring it)
  • A torch/fire swung as an improvised weapon
  • A lantern/fire source as an improvised thrown weapon

My character is a halfling who of course travels light, and I try not to carry anything that emits visible auras or significant magic auras, so I really do just have my crossbow, knife and armor for the most part. I have 4 pathfinder pouches to hide small magic items though so I’m not opposed to carrying anything that can fit in those pouches; I just don’t want to be caught with a giant glowing quarterstaff; my character often has to pass as an innocent little (human) girl.

Is there any option for dealing with swarms like that? Are there items I could use or preferably tactics I could use to actually damage a swarm (or cause damage to them)? Or is running my only option when faced with a swarm when alone?

Where can I find the other Channel Divinity options for Clerics that are hinted at in the PHB?

For a Cleric, the PHB shows two Channel Divinity powers: Turn Undead and Divine Fortune.

However, it says there are other Channel Divinity powers, but I can’t find out what these are.

What are those other options and where can I find them? Are these (and the previously mentioned ones) available to a first level character?
