network – Hping3 not working on BigIP target server

I have a BigIP target server and try to meassure the (average) rtt. Usually I do this with sudo hping3 -S -p 80 <target>.

hping3 works fine with the listed parameters for arbitrary hosts, but for this server – I know it’s a F5 BigIP the tool doesn’t seem to work.

I can curl the target server at port 80 and 443 and browse it and nslookup it, however
hping3 returns the following:

sudo hping3 -S -p 80  -VVV XXXXXXXXXX
using ens192, addr: XXXXXXXXXX, MTU: 1500
HPING XXXXXXXXXX (ens192 XXXXXXXXXX): S set, 40 headers + 0 data bytes
--- XXXXXXXXXX hping statistic ---
5 packets transmitted, 0 packets received, 100% packet loss
round-trip min/avg/max = 0.0/0.0/0.0 ms

Not even showing a single line with sent packages although using -VVV.

To confuse me even more the requests for port 443 result in 0.0ms responses:

sudo hping3 -S -p 443 XXXXXXXXXX
HPING XXXXXXXXXX (ens192 XXXXXXXXXX ): S set, 40 headers + 0 data bytes

postgresql – Changing the target schema on export or import?

I normally do the following for SQL dumps:

pg_dump -U username -cOx database > dump.sql

And then restore it into a new database with:

psql -U username new_database < dump.sql

Currently the database tables are not in the public schema, but a schema named for a user. No reason for it. I think it happened when there was a migration from MySQL to PostgreSQL a few years back using a utility whose name escapes me.

I’d like to move everything into public. I know I can do this by editing the dump.sql, which is a slow process given the size of the file (which is pretty small in database terms).

Is there a way to do this when exporting or importing a SQL dump?

This is PostgreSQL 13, btw.

dnd 5e – If a spell is twinned, does the caster need to provide costly material components for each target?

The Divine Soul Sorcerer can gain access to the revivify spell pretty easily (along with other costly resurrection spells), which has a costly material component that the spell consumes (300 gp worth of diamonds).

If after a particularly rough battle, can the Sorcerer use revivify on two separate creatures who have died for the cost of just 300 gp worth of diamonds or would it require 600 gp worth?

For the sake of this question, assume that a dead creature is a creature and not an object. If it helps, you could consider the stoneskin spell as well.

❕NEWS – Famous Fund Manager: Bitcoin Price Target $ 100,000 | NewProxyLists

Anthony Scaramucci, founder of investment firm SkyBridge Capital, said Bitcoin could rise much more in the current cycle. In a new interview with Yahoo Finance, Scaramucci stated that Bitcoin could easily exceed $ 100,000.
According to her, given the macroeconomic backdrop, the Bitcoin price could reach $ 100,000 by February 2022.
What do you think of this prediction?

dnd 5e – Which spells require the caster to see a target creature or unoccupied area?

Spells that rely on sight

If you cast any of these spells while blinded or your vision is heavily obscured, the spell fails or is crippled. They all use the “that you can see” keywords when they are cast.

If vision is obscured after the spell is cast it may not matter but at least a caster using these spells might be nerfed by Fog Cloud or Darkness the same way Silence nerfs spells with a Verbal component.

javascript – Night / Dark Mode CSS Toggle in header Template File – How to Target Header, Body and Footer

In my header.php template, I have a button that looks like this: <button onclick="NightModeToggle()">Dark</button>

In my stylesheet, I have the following CSS code:

  background-color: black;
  color: white;

In an already enqueued JS file, I have this:

function NightModeToggle(){
   var element = document.body;

I understand that it targets the body by using this line: var element = document.body;

My question is, how do I add additional targets so that I can change the background color and text color of the header and footer as well?

I tried modifying the code into this (without result):

var element = document.body;
var element = document.header;
var element = document.footer;

Any ideas?

Two aeroplanes 1 and 2 bomb a target in succession. Probability of 1 and 2 hitting correctly are 0.3 and 0.2. ….

Two aeroplanes 1 and 2 bomb a target in succession. Probability of 1 and 2 hitting correctly are 0.3 and 0.2. The second plane will bomb only if first misses the target. Find the probability that target is bombed by the second plane

I want to know why the complementary method cannot be used here ie.$$P(B) = 1-0.3=0.7$$

Which gives the probability that the target is never hit by the first plane.

Note: I know the correct way to do this, I just want to know why this is wrong.

8 – Use entity reference to target revisions of an an entity

I’m building a custom entity document which supports revisions. Revisions are seen as versions of the document (v1.1, v1.2, …), the title field is revisionable as well.
Then there is a custom entity customer, which needs to accept documents. On creation of a customer, I need to point out which revision of the document is suitable for this customer.

I have an entity reference field on the customer to target a document. However, I’m not achieving to target revisions of a document.

I tried entity reference display in views (with a view that supports revisions) but I’m not able to select it in the field settings (no eligible view found). Probably because I can only select ‘Document’ as target type and not ‘Document revisions’.

I tried entity reference revisions module but gave me the same results. This module just keeps track of changes in parent vs child revisions (I guess).

would expect document revisions being available here

I would expect document revisions being available in the settings above!

Any suggestions on how to do this properly, am I missing something? I want to make use of core as much as possible for this one.

blockchain – How is the Target Hash determined?

There are two values in play here, and the way your question is phrased makes me think you’re confusing them.

Every block has:

  • A hash (computed by double-SHA256 the block header, including timestamp, nonce, version, Merkle root, nBits which encodes the difficulty, and previous block hash)
  • A target (computed from the difficulty only)

000000000000000000084bc771b929b0780276b1c31cec10a96921b1e53b970a is the hash of block number 669945. Just feeding the block’s header exactly to double-SHA256 gives you this output (including the zeroes up front). It gets interpreted as a number:

  • 0x000000000000000000084bc771b929b0780276b1c31cec10a96921b1e53b970a (in hex, with zeroes explicit)
  • 0x84bc771b929b0780276b1c31cec10a96921b1e53b970a (in hex)
  • 794600089940753232651370066465976921098309156434843402 (converted to decimal)

The target is the maximum allows value that hash must have to satisfy the proof-of-work requirement. It is determined entirely by the difficulty(*) (which on its turn is determined by the timestamps of the previous blocks in the chain it is built on). That difficulty is also stored in the block header itself as the “nBits” value. The nBits value for block 669945 is 0x170d21b9; it encodes 0x0d21b9 · 2560x17 – 3, which equals:

  • 0x0d21b900000000000000000000000000000000 (in hex)
  • 1257769770588612382309009370720465882998915202417688576 (converted to decimal)

Since 794600089940753232651370066465976921098309156434843402 (the actual hash’s value) is less than 1257769770588612382309009370720465882998915202417688576 (the target value), proof-of-work is valid for this block. And of course it is; if it wasn’t, you would never have heard about this (attempted) block candidate.

(*) Technically speaking, the term “difficulty” is only used for representing how hard a block is for human consumption. Internally only nBits and the full target value are ever used. Difficulty is defined as 0xffff·25626 / target. The lower the target, the harder it is to find a block whose hash is below it, and thus the higher the difficulty is.
