How does a Lightning transaction work if a game starts without Bitcoin or wallet?

Let's say that Alice wants to give Bob 1₿, and that Bob still has no regular wallet address in the blockchain.

The classic example assumes that Bob himself locks a bitcoin on the blockchain, and Alice and Bob both finance a channel between them. But what if Bob does not have a Bitcoin yet and Alice wants to give it to him via Lightning? Then he could get Bitcoin from Alice, make transactions with him, with other parts of the Lightning Network, and make a slow, expensive, blockchain transaction only when he would be ready to cash out.

I know it's possible because I've been able to test that with two different Lightning apps with separate wallets. I've funded a Lightning wallet, and opened another app with 0 balance and no ordinary wallet. I was able to finance the second wallet instantly. But I'm not sure what is happening to get there.

The weird white screen of the MacBook Pro when restarting the mouse and trackpad does not work

The keyboard and trackpad of the 2016 MacBook Pro do not work but the touch bar works,

https://imgur.com/a/ksjAVi5 This is what is displayed when booting, this article refers to the only similar problem I found on the https://www.ifixit.com/Answers/ network. View / 237198 / MacBook + Air + boots + to + strange + screen + – + What + should I + do

It worked fine yesterday so I went to school in the morning, then when I opened it, the mouse and keyboard did not work and there was a screen that talked about the connection or the configuration from an external keyboard or mouse. works and I'm now stuck here

Microsoft Excel – if the formula does not work as expected

whole formula that does not work properly:
= IF (VLOOKUP (K28, AD: AF, 3, FALSE) = "offset", "offset", IF (L28 = "", VLOOKUP (N28, AM: AN, 2, FALSE), VLOOKUP (L28, AJ: AN, 5, FALSE)))

This part of the formula works by itself and returns what I need:
= IF (L28 = "", VLOOKUP (N28, AM: AN, 2, FALSE), VLOOKUP (L28, AJ: AN, 5, FALSE))

However, when combined with the rest of the formula, this part of it does not work:
VLOOKUP (N28, AM: AN, 2, FALSE).

All other parts of the formula work well.
Enjoy the help in advance.

network – A question about proof of work

I will describe my question with the help of an example.

Suppose the network is working on adding block # 100 to the blockchain. An attacker recreates block 99 with a combination of transactions that are "legitimate", which means that they can be hashed with the same hash that the one used by block 99 (and that it does not). there is no double expense).

Then it broadcasts the block over the network. How does the network know this block is wrong and reject it?

I think it has something to do with PoW, but I'm not 100% sure. Can any one explain me the rejection process with a detailed explanation?

Thank you in advance for any answer!

redhat enterprise linux – The application JBoss Fuse does not work in docker construction

I hope someone can help me solve a problem that I have with JBoss Fuse – especially AMQ. I'm using version 6.0.0.redhat-024 with 6.0.0.redhat-024-p5. I'm trying to deploy this in a container but seems to have a problem with AMQ. The problem – when deploying my application – is as follows:

(root@4ca73a25d4cf home)# client -r 2 -d 60 -u admin -p admin "features:install example-app"
Refreshing bundles org.springframework.context.support (104)
Error executing command: Could not start bundle mvn:com.example/example.broker.services/1.0-SNAPSHOT in feature(s) example-base-0.0.0: Unresolved constraint in bundle example.broker.services (254): Unable to resolve 254.0: missing requirement (254.0) osgi.wiring.package; (osgi.wiring.package=org.apache.activemq)

Obviously, this sounds like a missing addiction problem, but, I am convinced that it is a Red Herring, as this problem only occurs when I try to make it work. install the application as part of the process of generating the fixed menu. To prove it, I have:

  1. Installed the application successfully on a virtual machine of the same operating system
  2. Installed the application in an empty container without using the docker generation
    (that is, running a container, running it, and just running the Fuse installation
    and the application manually)

The two methods above are no problem: the application is installed and working as expected. The commands used in the above installations are extracted from the Docker file that I use for the build. This problem seems to be related (somehow) to the construction of the fixed menu.

When the application installs something seems to do something to AMQ. When I create the container at the time of installation of the application, the features of QMA are satisfactory:

(root@8cdbdd27720a home)# client -r 2 -d 60 -u admin -p admin "osgi:list | grep 118"

( 128) (Active     ) (            ) (       ) (   60) JBoss A-MQ Fabric (6.0.0.redhat-057)

When I update, run, stop the packets, everything is fine:

(root@8cdbdd27720a home)# client -r 2 -d 60 -u admin -p admin "osgi:refresh 118"

Does anyone know why this is happening? Why does this work when done manually but as part of the build of the fixed menu, it fails.

dnd 5e – How does targeting work when launching Call Lightning via Glyph Of Warding

I do not think Call Lightning works with Glyph of Warding

Glyph of Spell Glyph The Glyph feature indicates that the spell you have selected:

The spell must target a single creature or region.

Call Lightning says:

When you cast the spell, choose a point you can see under the cloud. A lightning bolt rises from the cloud to this point.

So, while the cloud itself fills an area, the called lightning calls a point, which is neither a zone nor a creature.

In addition, Call Lightning says:

The spell fails if you can not see a point in the air where the storm cloud might appear (for example, if you are in a room that can not accommodate the cloud).

This means that you must be in the same very large room or outside, so that you have a direct view of the area. If that is the case and you are, a DM may decide that the cloud is summoned, but the remaining effect is not a valid Glyph of Warding application.

Contest – $ 15 for design work

I will give about 2-3 days maximum. Payment: Paypal.

I need someone to design this image. The text will be modified later, but the layout and dimensions of the text will remain the same. It will run on a 8.5 x 5.5 flyer so create the 8500x file at 5500px and the text will cover most of it. Do whatever you want !! I want it to look pretty and easy to read and of course the bold letter must be distinguishable. Y
SEMrush

His real estate related. So maybe some transparent houses in the background? Maybe some different color variations? Maybe separate the text in some way? Whatever you want … go for it.

Ubuntu 18.04: Long edge duplex printing mode is selected but does not work

If I choose to print a document (pdf, txt) with several pages with Duplex "Long Edge", activate with Evince, Gedit, … under Ubuntu 18.04.x, it continues to print with Duplex Off.

It worked with Ubuntu 16.04 LTS and I also tested on Ubuntu 19.04 and it works. So the problem is about 18.04 LTS.

We use a remote printer on an Ubuntu 19.04 print server.

It is as if the files sent by Ubuntu 18.04 to the print server were not interpreted correctly by the print server.

Any help would be appreciated, I do not know if the problem is with Ubuntu, cups, poppler, … Thanks!
