  • Defaults for null values

    - by OldFart
    Working on a Powershell script I had several places where I wanted A unless it was null, else B. Essentially the ?? operator in C#. I ended up writing the function shown below, but I can't help but think there is a built-in way to do this. Is there a better, built-in, way? function Get-ValueOrDefault() { foreach ($value in $args) { if ($value -ne $null) { return $value } } } I think this works better: function Get-ValueOrDefault() { $args | select -first 1 }

  • What is this particular type of revelation called?

    - by Lars Haugseth
    After struggling with a particular problem or bug in some part of my code for hours, without getting anywhere, I often get a sudden revelation as soon as I try to explain the problem to one of my coworkers, or while formulating it in writing for posting to some forum. Does this kind of experience have a name? Where can I read more about it and how to train it? Do any of you use this consciously in your day-to-day work?

  • Inexpensive ways to add seek to a filetype object

    - by becomingGuru
    PdfFileReader reads the content from a pdf file to create an object. I am querying the pdf from a cdn via urllib.urlopen(), this provides me a file like object, which has no seek. PdfFileReader, however uses seek. What is the simple way to create a PdfFileReader object from a pdf downloaded via url. Now, what can I do to avoid writing to disk and reading it again via file().

    - by mkoryak
    Are there any practical ways to tell what part of the DOM was modified if you know that it will be modified? I am writing a plugin that will be running along with javascript that i did not write. an event will be triggered before DOM is modified, and one event will be triggered after the modification. It is my job to decide what was changed. is this possible, and if so what is the least horrible way to do this?

  • Book recommendation for learning server management and Apache

    - by japancheese
    Hello, I'm currently managing a site that I feel could be optimized and utilized to be much faster, however, I'm having difficulty finding reliable information to do it. I find the Apache documentation to be a hard read, and too technical about things I don't have a strong grasp on. I'm just looking for a good beginner/intermediate book about server administration to learn as much as possible about Apache, as well as how to create a nice secure, robust server that doesn't crash at the first hint of unusual traffic surges. Thanks to anyone who can point me in the right direction.

  • Ruby / rubyzip alternative capable of handling rar/tar/zip/7z?

    - by Nick Gorbikoff
    I was wondering if anyone knows of rubyzip alternatives for Ruby, that can handle various formats in particular zip / rar / 7z? I know of libarchive, but it's not complete for my purposes ( it's a good gem thou). (To clarify, libarchive - won't work for me - cause I need to be able to run in on Windows. ( Yeah I know sucks to be me)) Right now I end up running system commands to the os, but I'd like something OS independent, and capable of handling those formats - reading and writing. Thank you

  • Get path of inserted usb in dbus

    - by kjakeb
    Hello, I'm writing a program in python using dbus that detects inserted usb drives and manipulates the files inside of them. However, I can't seem to retrieve the path on my system of an inserted usb. Is there someway that I can get the path of an inserted usb in dbus, perhaps by using the GetProperty() method? I have tried using GetProperty("block.device"), but that returns /dev/sdc1 which doesn't exist on my system. Thanks in advance for any help!

  • .NET Serial Port: Port Configuration Dialog

    - by sheepsimulator
    I'm going to be writing a small app based on the .NET SerialPort class. Is there a generic dialog available for setting the port settings, ala baud rate, data bits, stop bit, parity bit, flow control, etc? I didn't see one in the MSDN documentation, but I would think that one exists, since that stuff doesn't change.

  • Good comments on changesets in sourcecontrol

    - by Roma
    We need to develop guidelines for writing comments when we register code in version control system (such as TFS). E.g., when we submit a bugfix, we create a comment "Fixed bug #..." We tried to brainstorm on this topic, but most of the ideas bring too little added value. I would appreciate any suggestions for this.

  • Why doesn't XmlSerializer support Dictionary?

    - by theburningmonk
    Just curious as to why Dictionary is not supported by XmlSerializer? You can get around it easily enough by using DataContractSerializer and writing the object to a XmlTextWriter, but what are the characteristics of a Dictionary that makes it difficult for a XmlSerializer to deal with considering it's really an array of KeyValuePairs. In fact, you can pass an IDictionary<TKey, TItem> to a method expecting an IEnumerable<KeyValuePairs<TKey, ITem>>.
