  • When to delete a branch from Git?

    - by lupefiasco
    I'm relatively new to Git, and want to get advice on best practices for deleting branches. After I've created and merged a branch back into master, should I leave it hanging around for historical purposes, or should I delete it as soon as it's no longer needed for housekeeping purposes?

  • Understanding omission failure in distributed systems

    - by karthik A
    The following text says this which I'm not able to quite agree : client C sends a request R to server S. The time taken by a communication link to transport R over the link is D. P is the maximum time needed by S to recieve , process and reply to R. If omission failure is assumed ; then if no reply to R is received within 2(D+P) , then C will never recieve a reply to R . Why is the time here 2(D+P). As I understand shouldn't it be 2D+P ?

  • Standalone application in C, a good idea?

    - by chutsu
    The term has several definition according to Wikipedia, however what I'm really interested in is creating a program that has all its needed dependencies included within the source folder, so the end user doesn't need to install additional libraries for the app to install. For example, how Mac apps has all its dependencies all within the program itself already... or is there a function that autotools does this? I'm programming in the Linux environment...

  • Storing images for multiple web sites

    - by Orkun Balkanci
    I've got two web sites (written in c#) which are pretty common: One is an admin site (cms) where you add images into content as needed, through editor pages. Second is the site where the content with images is shown. Images should be stored outside these two sites but where and how?

  • Overinclusion of libraries C++

    - by wyatt
    I'm reading about how to put a makefile together, but no-one seems to mention what to do if your files require different sets of libraries, they all seem to use the same set of libraries for each file. Since it seems unlikely that every single file has the same libraries, I take it the list they use must amalgamate all of the libraries required across the project. I just wanted to know if there's any downside to including too many libraries, or if the compiler works out which ones are needed and ignores the rest? Thanks

  • Erlang: What's a good way to automatically assign node names?

    - by mwt
    I want to have an EC2 based cluster that can grow and shrink at will. No node will be special in any way nor do I want them to have to coordinate their names with any other nodes. I don't want to hard code the names since I want to use one image and spin them up as needed. I understand nodes have to have names to communicate, though. What's a good strategy for automatically and dynamically coming up with a name at start script time?

  • Chrome not displaying a div

    - by Kyle Sevenoaks
    Click here to see a simple example of what I want. It's really easy, but for some reason Google won't display the "subTotalCaption2" div. It's part of a foreach loop, if needed I can add other codes. There is nothing else in the rest of the css to mess with this, I have checked about 10 times. See it live at euroworker.no/order (add items to basket) In FF and Chrome. Thanks.

  • Best practices for handling binary data in Ruby?

    - by StackedCrooked
    What are the best practices for reading and writing binary data in Ruby? In the code sample below I needed to send a binary file using over HTTP (as POST data): f = File.new("resp.der", "r") # binary file begin while true out.syswrite(f.sysread(1)) # out is an output stream (type IO) end rescue EOFError => err puts "Sent response." end While this code seems to do a good job, it probably isn't very idiomatic. How can I improve it?

  • How to handle main option with Getopt

    - by Jérôme
    I want to handle a feature which seems to me almost natural with programs, and I don't know how to handle it with Getopt perl package (no matter Std ot Long). I would like something like: ./perlscript <main option> [some options like -h or --output-file some_name] Options will be handled with - or --, but I want to be able to let the user give me the main and needed option without dashes. Is Getopt able to do that, or do I have to handle it by hand?

  • MySQL DATE_ADD usage, 5 day interval

    - by Webnet
    I'm trying to select the order total sum ($) and invoice count over a 5 day period in a single query. I can't seem to get this to happen though. The current query I have is here... SELECT COUNT(id) as invoice_count, SUM(orderTotal) as orders_sum, UNIX_TIMESTAMP(created) as created FROM ids_invoice WHERE DATE_ADD(created, INTERVAL +1 DAY) AND userId = '.$userId.$whereSql I'm not entirely sure DATE_ADD is the right function I'm looking for I'm fairly new to mysql date functions so perhaps I just missed the function I needed when going through mysql docs.
