ssl - Emacs wanderlust IMAP password authentication -

-

In emacs / wanderlust, if someone selects the 'clear' method of sending the password, but SSL enables for IMAP, is the password protected by SSL encryption? Specifically, the worrisome information is generated from the following paragraph in the manual:

There are two ways to use SSL, to start SSL communication only after a connection connection (normal methods) Second, In each session, start the SSL conversation using the STARTTLS command.

What is the first method to transmit passwords before or after SSL encryption? If first, the second (STARTTLS based) method ensures encrypted password transmission?

The password is safe, the difference between the two methods.

The difference between these approaches is in another aspect: the first step starts immediately after a TLS connection TCP handshake, and before Any IMAP exchange starts. Therefore, it uses a different port compared to regular IAPAPs, but can be used with the IAPAP servers, that their traffic is not only TLS support built through tunnels.

With the second method, for regular IMAP ports and an unencrypted IMAP exchange, however, before sending any credentials or any other personal data, this server should upgrade the connection to a TLS connection , And only starts the IMAP exchange (including password transfer) after This upgrade succeeded, this method allows encrypted IMAP from the default IMAP port, This is an IMAP server that can handle this IMAP protocol extension.

Nowadays, most servers support STARTTLS, so both methods are mostly equivalent to whatever Wanderlust uses as default.

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
