While going through a Quagga document, i came across following line.
http://www.nongnu.org/quagga/docs/docs-info.html#How-to-Announce-RIP-route
"Quagga ripd does not support the non-sequential netmasks that are included in RIP Version 2. "
What do we mean by " non-sequential netmasks" can anybody explain me with example or send a link where i can find some detail.
Here is the answer. I got this answer from quagga dev team.

Hi Every,
May I ask you why this will happen after I create a new Julia package, and register it to https://juliahub.com/ui/Home.
I think I already check the every steps very carefully, but still not figure it out where the bug comes from.
Can anyone tell me how to solve this problem? Many thanks!
Here is the Pull Request that Eric mentioned which tells you exactly what went wrong:
https://github.com/JuliaRegistries/General/pull/48736
Quoting from there:
Name does not meet all of the following: starts with an upper-case >letter, ASCII alphanumerics only, not all letters are upper-case.
Name is not at least 5 characters long
Repo URL does not end with /name.jl.git, where name is the package name
Package name similar to 2 existing packages.
Similar to ALFA. Damerau-Levenshtein distance 2 is at or below >cutoff of 2.
Similar to BBI. Damerau-Levenshtein distance 2 is at or below cutoff >of 2.
Basically, ABBA is not a very descriptive package name, and the general registry favours unambiguous and self-explanatory names.
Now these are only auto-merge rules, which means that they prevent automatic addition of your package to the general registry, but not the addition per se. If you believe that there are good reasons why ABBA is the perfect name for your package and it should be registered under this name, just comment on the PR and it might get manually merged.
Encountered this when using openTSDB and I want to make sure I'm using the right function.
Difference of sum and zimsum is described here: http://opentsdb.net/docs/build/html/user_guide/query/aggregators.html
zimsum is suppose to add the data points together and fill zero if missing. I supposed 1m-zimsum and 1m-zimsum-zero should return same results. I have a single data logged in openTSDB once at 2 AM. I got a dot with 1m-zimsum but a line with 1m-zimsum-zero. Could anyone kindly explain?
I'm not super familiar with statistics and openTSDB. Please forgive me if stupid question is asked.
I was reading a question in SO and came up with the !! operator. Ive been working with R for some time and never have seen it. First, Ive search for questions about it, and couldnt find one in SO (so this may be a duplicate). Also, go back to diferent R operators post and pages, and no one says anything of it.
In the question, the !! preceded an R oject, like:
> !!object
Thanks for the help.
P.D.: If its a duplicate, please close.
I have checked a lot of DICOM Images about CTDI Phantom Type Code Sequence Attribute (0018,9346) Values. I found 2000 times the value: 1)
What do these signs "1)" mean?
https://dicom.innolitics.com/ciods/ct-image/ct-image/00189346
You should probably ask the engineer, who performed the studies, or the technician who had installed the machine an did setup of the worksation.
I could only guess and I would take a shot that this sequence means, that "there was a phantom used during the study".
You need to get used to the fact, that DICOM standard is something like a suggestion, not a requirement. For example, when you get a series where 0008,1030 ("Study Description") has value "CTChest", you shouldn't assume that this is a CT of the chest, as it could be any type of the examination.
In R, one sometime sees people making references to fortunes. For example:
fortune(108)
What does this mean? Where does this originate? Where can I get the code?
Edit. The sharp-eyed reader would have noticed that this question marks the 5,000th question with the [r] tag. Forgive the frivolity, but such a milestone should be marked with a bit of humour. For an extra bit of fun, you can provide an answer with your favourite fortune cookie.
It refers to the fortunes package, which is a package that contains a whole set of humorous quotes and comments from the help lists, conferences, fora and even StackOverflow.
It is actually a database or small dataframe you can browse through.
library(fortunes)
fortune()
To get a random one. Or look for a specific one, eg :
> fortune("stackoverflow")
datayoda: Bing is my friend...I found the cumsum() function.
Dirk Eddelbuettel: If bing is your friend, then rseek.org is bound
to be your uncle.
-- datayoda and Dirk Eddelbuettel (after searching for a function that
computes cumulative sums)
stackoverflow.com (October 2010)
If you want to get all of them in a dataframe, just do
MyFortunes <- read.fortunes()
The numbers sometimes referred to, are the row numbers of this dataframe. To find everything on stackoverflow :
> grep("(?i)stackoverflow",MyFortunes$source)
[1] 273 275
> fortune(275)
I used a heuristic... pulled from my posterior. That makes it Bayesian, right?
-- JD Long (in a not too serious chat about modeling strategies)
Stackoverflow (November 2010)
And for the record, 108 is is this one:
R> library(fortunes)
R> fortune(108)
Actually, I see it as part of my job to inflict R on people who are
perfectly happy to have never heard of it. Happiness doesn't equal
proficient and efficient. In some cases the proficiency of a person
serves a greater good than their momentary happiness.
-- Patrick Burns
R-help (April 2005)
R>
They're humorous (sometimes snarky) comments collected from the R lists.
install.packages("fortunes")
Or more generally
install.packages("sos")
library("sos")
findFn("fortune")
A quick search on CRAN turns up the fortunes package, which basically just prints random witty quotes related to R. The concept is based on the fortune program from Unix.
