large letter outline stroke with sass - css

I have been using the text shadow trick of using a large text shadow to create the illusion of a larger stroke width for a letter outline. It works as is for my needs but I recently started using sass and was wondering if it was possible to convert my current css rules:
#title {
top:10px;
left:-30px;
color:white;
transform: scale(.8,1);
position: absolute;
font-size: 100px;
font-weight: bold;
text-transform: uppercase;
-webkit-font-smoothing: antialiased;
text-shadow: 0 0 10px hsl(216,100%,50%),

into something much shorter using the for loop controls in sass.
so far I've seen instructions on how to use the for loop to create multiple rules, but not yet to create multiple properties of a single rule. If it is possible, could someone give me an example? Or point me to documentation that I have been having a hard time finding? Or if it is not possible please let me know, so that I can move on in peace.


You can use the for loop to create your rule as a string, then use interpolation to apply it to the text-shadow property.
codepen
$text-shadow: '';
#for $i from 1 through 20 {
$text-shadow: $text-shadow + if($i == 1, '', ', ') + '0 0 10px hsl(216,100%,50%)';
}
text-shadow: #{$text-shadow};

How to prevent background image from jumping on transition?

Is it possible to prevent background image from jumping effect when animation looping?
What i already tried:
Changing animation type from transition, to position change (left: 0 -> left: -100%)
Replacing background image to background gradient but result is the same

As the background is repeated we can have this animation definition and can control the speed of the animation by setting 60-120s as per your requirement for the animation property.

/*use negative width if you want it to flow right to left else and positive for left to right*/

Glowing animation on SVG using CSS

I have similar thing applied on text and that works fine using text-shadow:

So I tried same thing with SVG using webkit-filter: drop-shadow witch if you un-comment the line successfully drops shadow on SVG but I can not make it work to animate. I cant seem to find anywhere example of animation of SVG using shadow, i find some using fill but that does not interest me.
Any guidance is appreciated.

Your syntax of multiple shadow is wrong, it need to be like below:
.svg-shadow {
animation: svg-shadow 1.5s ease-in-out infinite alternate;
}
#keyframes svg-shadow {
from {
filter: drop-shadow( 0 0 5px #fff) drop-shadow( 0 0 15px #e60073) drop-shadow( 0 0 20px #e60073);
}
to {
filter: drop-shadow( 0 0 20px #fff) drop-shadow( 0 0 25px #e60073) drop-shadow( 0 0 40px #e60073);
}
}

Converting a single cell count matrix that is currently a text file into a data frame

I have downloaded some files off the internet that are single cell count matrices, and I want to convert them into dataframes in R. I have used readLines to read the text files in, but now each line of the file looks like this:
3110082J24Rik\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0\t0
For some context, the columns in a single cell matrix file are the cells, and the rows are the genes. The numbers in the file indicate the number of times that the gene (for this line, 3110082J24Rik) appears in each cell. Anyone have any idea how I could do this? Here is some sample data:

In the ideal world, each of the labels at the top that starts with "W" would be a separate column with the corresponding numbers for each gene also in that column.

Handle error with try in R

I am trying to make function that returns geometric mean with data.
I want to make loop with try() to pass valid data, but what i tried actually didn't worked.
This is function
R=function(g)
{
k=1
n=length(g)
for(i in 1 : n)
{
ifelse(g[i]>0, k<-k*g[i], stop("Negative component"))
k
}
t=k^(1/n)
t
}
And i want to use this function in this loop
set.seed(123)
data <- matrix(rnorm(10000, mean=3), ncol=25, dimnames=list(NULL, paste("X",
1:25, sep=".")))
v=rep(0,400)
for(i in 1 : 400)
{
try("v[i]=R(data[,i])",TRUE)
}
v
I want to get means for valid data, but it makes all value to 0

Can you let me know where was wrong??
Thanks

I guess the problem is with the missing declaration of t as a numeric vector and the syntax of try() function. The following code should work, it worked for me.
R=function(g)
{
t = numeric(length(g))
k=1
n=length(g)
for(i in 1 : n)
{
ifelse(g[i]>0, k<-k*g[i], stop("Negative component"))
}
t=k^(1/n)
t
}
set.seed(123)
data <- matrix(rnorm(10000, mean=3), ncol=25, dimnames=list(NULL,paste("X",
1:25, sep=".")))
v=numeric(400)
for(i in 1 : 400)
{
try(v[i]<-R(data[i,]),TRUE)
}
v

Error when decrypting with OpenSSL rsa key

I am trying to write a simple application to encrypt/decrypt a buffer of unsigned char using OpenSSL RSA encryption. I have my public key and encrypt an array with
unsigned char plain [13] = "Hello World!";
unsigned char encrypted[1024]={};
unsigned char decrypted[1024]={};
int padding = RSA_PKCS1_OAEP_PADDING;
int flen = 13;
int res = RSA_public_encrypt(flen, plain, encrypted, rsa_pbk, padding);
where rsa_pbk is an RSA structure that contains the key. If I print it, the result is the following hexadecimal array:

I am a little bit suspicious of the zeros at the end, but it could be ok. But, when I try to decrypt it with
flen = keysize - 50;
RSA_private_decrypt(flen, encrypted, decrypted, this->rsa_pvk, padding);
I get the following error
error:0407A079:rsa routines:RSA_padding_check_PKCS1_OAEP:oaep decoding error
error:04065072:rsa routines:RSA_EAY_PRIVATE_DECRYPT:padding check failed
that I'm not able to understand. Does anybody know what it means and why it arises?

Manual page states that: RSA_public_encrypt() returns the size of the encrypted data. RSA_private_decrypt() returns the size of the recovered plaintext. On error, -1 is returned; the error codes can be obtained by ERR_get_error(3).
Your code should look like this:
unsigned char plain [13] = "Hello World!";
unsigned char encrypted[1024]={};
unsigned char decrypted[1024]={};
int padding = RSA_PKCS1_OAEP_PADDING;
int flen = 13;
int res = RSA_public_encrypt(flen, plain, encrypted, rsa_pbk, padding);
flen = res;
res = RSA_private_decrypt(flen, encrypted, decrypted, this->rsa_pvk, padding);
