I want to create an image that has the text as transparent like this (imagining that black is transparent)    So in photoshop I have tried selecting 'color range' and choosing the white and then getting the inverse selection and deleting it from a new white layer. But this comes out very pixelated like this (I have put a black layer underneath to show through the transparence):    How can I do this without the pixelated edges? The ideal situation here would be if there was a 'transparent clipping mask'
Okay, this should be super easy to do but I just can't find the way.  I have a background image with a solid colour layer on top of it, and I would like to add text on top of everything in such a way that the filling of the text is the image in the background. I have tried selecting the text shape and deleting that selection shape in the solid colour layer, but it just looks wrong.   Can anyone help me with this? Many thanks in advance.
How to recover deleted files? How do I delete files that are locked when no other app can delete them? So I found out that I had a Trojan on my external hard drive. My anti-virus app killed it, but it has created a bunch of random files on my computer which cannot be deleted. These are image files. They cannot be renamed - using any method - nor can they be moved, cut, copied, permanently deleted or even opened (in any program).  How can we rid these files from our system?  I have tried:   Right-click > Delete Shift+Delete (Permanently Delete) Swearing   and then:   FileASSASSIN from MalwareBytes Eraser program sdelete program several commands in cmd   but none of them have been successful. How can I completely obliterate these files? Electric monopoles do exist, but why cannot magnetic monopoles exist?

Swapping right shift and delete key using xmodmap I'm unsure how to swap these 2, this is the thought process I had but am unsure how to get it working:  remove sh = Shift_R remove dl = Delete  keysym Delete = Shift_R keysym Shift_R = Delete  add sh = Delete add dl = Shift_R   This is based on the code I use to swap caps lock and control.  Any thoughts?  xmodmap output:  dan@lantea:~$ xmodmap -pke | grep Shift_R keycode  91 = Shift_R NoSymbol Shift_R keycode 119 = Shift_R NoSymbol Shift_R dan@lantea:~$ xmodmap -pke | grep Delete keycode  62 = Delete NoSymbol Delete Kepler problem in time: how do two gravitationally attracted particles move? Two particles with initial positions and velocities $r_1,v_1$ and $r_2,v_2$ are interacting by the inverse square law (with G=1), so that  $$ {d^2r_1\over dt^2} = - { m_2(r_1-r_2)\over |r_1-r_2|^3} $$ $$ {d^2r_2\over dt^2} = - { m_1(r_2-r_1)\over |r_1-r_2|^3} $$  (the inverse square law along the line of separation). What is the complete solution of these differential equations? What is the position of the two objects as a function of time?  After reading a lot on Wikipedia, I've come to the definition of center of mass and relative coordinates:   $$R(t) ~=~ \frac{m_1 r_1 + m_2 r_2}{m_1+m_2}$$  $$\ddot{r}(t) r(t)^2 ~=~ (m_1+m_2)G$$  Where $R$ is the center of mass, and $r$ is the displacement between the particles... Is this correct? How do I proceed to solve the differential equation? I'm looking to have cell borders automatically applied when a cell is not empty. I thought I could use conditional formatting for this, but it doesn't seem to be an option.

Thanks! What's the difference between postfix/smtp and postfix/smtpd A bit confused when reading through the logs of my smtp/mail server, I'm turning this questions to you guys.   In the maillog files I'm seeing entries for postfix/smtp as well as postfix/smtpd. I can also see that there are possible settings for smtp as well as smtpd in the file main.cf  Trying to find some reasonable explanation through google search seemed to be impossible, so here is my question to you guys.  My server was kind of compromised and the spam mails where going through postfix/smtp and not smtpd. Please help me to understand. Thanks in advance! Based  I'm trying to setup Tomcat Server, I have successfully installed it and tested it. Then I stopped it as recommended in the tutorial.

Thanks. context menu parent? Prove that $f$ has a fixed point . Why are SMD LEDs shipped in a sealed bag containing desiccant? I had a selection of 0805 LEDs in my last Mouser order and was a bit surprised to discover they arrived in heat-sealed (rather than folded and taped with sticker) bags containing a desiccant bag and some sort of litmus-esque paper indicator saying something about baking them if the dots on it went pink (instead of blue).    A quantity of through-hole LEDs I had in the same order just came in the regular ESD-protective bag, folded over with a sticker.  What's up with SMD LEDs that they work so hard to keep them dry? Surely their dryness can't be assured once they're installed. Does it have to do with their solderability or something? Why would that be different than other SMD parts?

(A)$ f(z) = Kz^3$ $∀ z∈\Bbb{C}$ (B) $f(z)$ is a constant function (C) $f(z)$ is quadratic function (D) No such $f$ exists   My attempt : I can deduce that since $f(z) = f(iz)$ and since $i^4=1 \implies f$ must involve only fourth powers of $z$ . Hence $f(z)=a_1z^4+b_1z^8+c_1z^{16}+ \cdots $-------(1)  Also for $|z| \ge 1 $: let C.   Then $|g(z)| = |f(z)|/|z^3| \le k$ => By the Cauchy estimate theorem we can prove that :  $f(z)/z^3$ is a constant function $= c $   $\implies f(z)=cz^3$ for $|z| &gt; 1$     ...........(2)  From (1) and (2) ; we get  there does not exist a function like this ?  My textbook answer says it's a constant function ?
