I've written a DNS tool in Node and would like to know if there's a better and more efficient way of handling the conversion from an IP to a long. I'm not too good at bitwise just yet and would like to hear any suggestions. Psuedo-code has been provided below.

I have designed a database for my institute. Here I have attached my design for better understanding.
So I am expecting your reviews who are professional for the database design.
Thank you.
Hi I'm wondering if its possible to omit empty parenthesis when chaining in coffeescript.
for example
myFunction = -> [...]
chain1 = -> [...]
chain2 = -> [...]
myFunction().chain1().chain2()
to instead
myFunction.chain1.chain2
This particular example is verilog, but my question is more about the state machine structuring, which would be relevant to both VHDL and verilog.
So if I have a state machine, this one is fairly simple:
always@(posedge m_axi_clk) begin
if(m_axi_resetn == 0) begin
current_state <= ...
100 queries is not fine. It's OMG and WTF. You should use Select ... from table where id in set

I am creating a database project in java using file handling. The program is working without compiling error. Following points are not working

I am practicing my code by writing a small application that lets the user search drives for their given input string. I am only returning the fullname of the files. What I have now is the following method to retrieve those fullnames:
private IEnumerable<string> FindOccurences(string searchQuery,...
Naming:
I am going to be blunt here... Your names are bad. Not horrible, but seriously bad.
var i = ids.split(",");
first thing jumping me here is, that you have a single thing (the id-string) named with a plural. next thing that jumps me, is that you have a collection with multiple element...
I have the following code which attempts to match all strings like "*SOMESTRING" (which can include numeric values), but not "*SOMESTRING*". For this I am using a negative lookahead as follows;*SEX and *AN01ZORA should match, \*PCCL\* should not match.
string s = " if 'L,....' MDC = '13' Then ...
Given a Node with a reference to a child, its next, its previous, and a variable for its value (1/2 tree, 1/2 doubly linked list structure), you have to find a way to flatten the structure.

I've got a JSON response that is contained in an outer array like this:

"name": "somename"
}

I've tried to convert this to object like this:

Based on my previous post I completely re-factored my code to make it object oriented.
Anything I could improve when it comes to:
Object oriented code;
Efficiency;
Readability.
Any other suggestions are also welcome!

So I have this peice of code I've been working on for quite some time. It's a ListView with a search filter. Inside each row, it contains a user Image, a User's name and how many friends they have in common. Also the row contains a button each, for actions.
I'm just indeed of some code refactori...

I was bored and burnt out on more serious projects.... until I saw this Computerphile video on YouTube. Now I'm inspired again. Now I feel like spending some time implementing that recursive algorithm in a little console program. Fortunately, recursion is unbearably slow in this case. So, I ended...
I recently bought this math-based boardgame for my little cousins, and am now trying to verify its design with some MATLAB code. The relevant parts of the game are:

There are three dice, the usua...

Considering that about 30% of the edits are approved, I think anonymous users seems to be very helpful in editing posts and therefore see no reason to ban them from suggesting edits. This is almost one out of three and is a bigger number than I expected.
Sure, one could argue that it should be a...
What can I do to optimize reading the user input?
Don't. For these kind of problems you will virtually never need to worry about time spent reading input.

I have a search-function, that searches for specific data within a huge Object.
Depending on how good a found entry matches, the finding gets "matchPoints" (or "Priority")

I have a large file that I want to refactor, my idea is to make helper classes with helper methods so that I can modularize methods, is that a good idea? For instance before refactoring:

I have a one website. I want to fetch perticular data contained in those website in a local file.
Has anybody done that with PHP? General guidelines and gotchas would suffice as an answer.
Given a set of non-negative integers, and a value sum, determine if there is a subset
of the given set with sum equal to given sum. On similar lines, Partition problem is to determine whether a given set can be partitioned into two subsets such that the sum of
elements in both subsets is same.
