  • Return current web path in PHP

    - by BenTheDesigner
    Hi All Currently developing a PHP framework and have ran into my first problem. I need to be able to drop the framework into any folder on a server, no matter how many folders deep, and need to find that directory to use as a base URL. For example, it currently works if I put the framework in the root of the server (http://cms.dev/), but if I were to put it in http://cms.dev/folder/ it does not work. Please advise, any comments welcome. BenTheDesigner

  • Does "I securely erased my drive" really work with Truecrypt partitions?

    - by TheLQ
    When you look at Truecrypt's Plausible Deniability page it says that one of the reasons for partition with solely random data is that you securely erased your drive. But what about the partition table with full disk encryption? How can you explain why the partition table says there's a partition of unknown type (With my limited knowledge of partition tables I think that they store all the partition filesystem types) and with solely random data? It seems that if your going to securely erase the drive you would destroy everything, including the partition table. And even if you just wiped the partition, the partition table would still say that the partition was originally NTFS, which it isn't anymore. Does the "I securely erased my drive" excuse still work here? (Note: I know that there's hidden truecrypt volumes, but I'm avoiding them due to the high risk of data loss)

  • What's the best way to handle modules that use each other?

    - by Axeman
    What's the best way to handle modules that use each other? Let's say I have a module which has functions for hashes: # Really::Useful::Functions::On::Hash.pm use base qw<Exporter>; use strict; use warnings; use Really::Useful::Functions::On::List qw<transform_list>; our @EXPORT_OK = qw<transform_hash transform_hash_as_list ...>; #... sub transform_hash { ... } #... sub transform_hash_as_list { return transform_list( %{ shift() } ); } #... 1 And another module has been segmented out for lists: # Really::Useful::Functions::On::List.pm use base qw<Exporter>; use strict; use warnings; use Really::Useful::Functions::On::Hash qw<transform_hash>; our @EXPORT_OK = qw<transform_list some_func ...>; #... sub transform_list { ... } #... sub some_func { my %params = transform_hash @_; #... } #... 1 Suppose that enough of these utility functions are handy enough that I'll want to use them in BEGIN statements and import functions to process parameter lists or configuration data. I have been putting sub definitions into BEGIN blocks to make sure they are ready to use whenever somebody includes the module. But I have gotten into hairy race conditions where a definition is not completed in a BEGIN block. I put evolving code idioms into modules so that I can reuse any idiom I find myself coding over and over again. For instance: sub list_if { my $condition = shift; return unless $condition; my $more_args = scalar @_; my $arg_list = @_ > 1 ? \@_ : @_ ? shift : $condition; if (( reftype( $arg_list ) || '' ) eq 'ARRAY' ) { return wantarray ? @$arg_list : $arg_list; } elsif ( $more_args ) { return $arg_list; } return; } captures two idioms that I'm kind of tired of typing: @{ func_I_hope_returns_a_listref() || [] } and ( $condition ? LIST : ()) The more I define functions in BEGIN blocks, the more likely I'll use these idiom bricks to express the logic the more likely that bricks are needed in BEGIN blocks. Do people have standard ways of dealing with this sort of language-idiom-brick model? I've been doing mostly Pure-Perl; will XS alleviate some of this?

  • How do I serve a large file using Pylons?

    - by Chris R
    I am writing a Pylons-based download gateway. The gateway's client will address files by ID: /file_gw/download/1 Internally, the file itself is accessed via HTTP from an internal file server: http://internal-srv/path/to/file_1.content The files may be quite large, so I want to stream the content. I store metadata about the file in a StoredFile model object: class StoredFile(Base): id = Column(Integer, primary_key=True) name = Column(String) size = Column(Integer) content_type = Column(String) url = Column(String) Given this, what's the best (ie: most architecturally-sound, performant, et al) way to write my file_gw controller?

  • How do I achieve virtual attributes in CakePHP (using code, not SQL) as implemented in Ruby on Rails

    - by ash
    Source: http://asciicasts.com/episodes/16-virtual-attributes I'd like to achieve a similar setup as below, but in CakePHP and where the virtual attributes are created using code, not SQL (as documented at http://book.cakephp.org/view/1070/Additional-Methods-and-Properties#Using-virtualFields-1590). class User < ActiveRecord::Base # Getter def full_name [first_name, last_name].join(' ') end # Setter def full_name=(name) split = name.split(' ', 2) self.first_name = split.first self.last_name = split.last end end

  • Detect if a method was overridden using Reflection (C#)

    - by Andrey
    Say I have a base class TestBase where I define a vistual method TestMe() class TestBase { public virtual bool TestMe() { } } Now I inherit this class: class Test1 : TestBase { public override bool TestMe() {} } Now, using Reflection, I need to find if the method TestMe has been overriden in child class - is it possible? What I need it for - I am writing a designer visualizer for type "object" to show the whole hierarchy of inheritance and also show which virtual methods were overridden at which level.

  • How to make vim display unicode

    - by Yitzchak
    I am trying to work with a utf-8 encoded xml file in vim 7.3 running on ubuntu. ASCII characters display normally but vim gives me gibberish instead of the unicode characters. After trying the following, I've reached the limits of my knowledge: 1) Checked that unicode was enabled by running set termencoding?. Output was termencoding=utf-8. 2) I installed the script from here (vim.org/scripts) 3) moved my ~/.vimrc file into ~/.vim 4) moved it back into ~ 5) followed the instructions in the accepted answer to this question. Is there some other variable I'm supposed to set? I know my system has the fonts I need. Update: Issue seems to be limited to html files for some reason.

  • Why abstract classes necessary?

    - by bala3569
    1.What is the point of creating a class that can't be instantiated? Most commonly to serve as a base-class or interface (some languages have a separate interface construct, some don't) - it doesn't know the implementation (that is to be provided by the subclasses / implementing classes) 2.Why would anybody want such a class? For abstraction and re-use 3.What is the situation in which abstract classes become NECESSARY?can anyone brief it with an example?

  • Network flooded with seemingly empty packets

    - by Adam Particka
    Let me preface this with the fact that I'm just a web developer at my company with little networking knowledge. Earlier today there was a department that lost all of their network connections so I popped open Wireshark and observed the influx of packets to my machine. There was normal traffic (ARP requests, etc.) coming in at ~50 packets every second. Then all of a sudden the log was flooded with packets arriving ~5000 a second. It looks as though they all contain the same data, just a looped sequence. We have someone here looking at it but I thought I would ask if anyone had seen anything like this before. Here's a selection from one of the captures in Wireshark. http://www.cloudshark.org/captures/06f950725c74

  • Floating point computer - Trouble with getting back correct results

    - by Francisco P.
    Having trouble with a challenge. Let's say I have a theoretical, base 10, floating point calculator with the following characteristics Only 3 digits for mantissa 1 digit for exponent Sign for mantissa and exponent How would this machine compute the following? 300 + \sum_{i=1}^{100} 0.2 The correct result is 320. The machine's result is 300. But why? Can't get where the 20 goes goes missing... Thanks for your time.

  • Features of Emacs that are complementary to Vim?

    - by redacted
    I've been using Vim extensively for a while now, and I really enjoy working with it. However, I keep reading praises for Emacs. I've decided to take a look at Emacs to round out my knowledge of the Unix editors (not to mention Emacs keybindings are used extensively). But! I'm happy doing most of my daily work in Vim. So ideally what I'd like is to look at (apart from basics) are the gaps that Emacs can fill, or things that it can just do better than Vim. I suppose the canonical example is Lisp/Scheme coding in Emacs versus Vim. Where would you start tinkering with Emacs to really appreciate its power, and to get a good idea of how its approach to editing differs from Vim, and how the editors can complement each other? What would be a good introduction in the same vein?

  • Optimal partition setup for Windows 7 on SSD

    - by Mike C.
    Hello, I'm setting up my system with Windows 7 right now, with knowledge that I am going to be getting a SSD in the future. What optimizations/setup should I do now to make a smoother transition in the future? Should I created two partitions - one for the OS and one for the data? Assuming this is the case, I would be able to easily ghost my OS partition onto the SSD in the future. If so, what should go on the OS drive besides the OS? Program files? If I install games or Visual Studio, should it go on the OS drive or the data drive? I can see the SSD filling up fast if I install all my program files on there. I've seen a few posts where people talk about leaving a portion of the SSD unformatted - is this something I should do? Thanks!

  • Binary Search Tree Contains Function

    - by Suede
    I am trying to write a "contains" function for a binary search tree. I receive the following error at compile "Unhandled exception at 0x77291CB3 (ntdll.dll) in BST.exe: 0xC00000FD: Stack overflow (parameters: 0x00000001, 0x001E2FFC)." The following is my code. struct Node { int data; Node* leftChild; Node* rightChild; Node() : leftChild(NULL), rightChild(NULL) {} }; struct BST { Node* root; BST() : root(NULL) {} void insert(int value); bool contains(int value); }; void BST::insert(int value) { Node* temp = new Node(); temp->data = value; if(root == NULL) { root = temp; return; } Node* current; current = root; Node* parent; parent = root; current = (temp->data < current->data ? (current->leftChild) : (current->rightChild) while(current != NULL) { parent = current; current = (temp->data < current->data) ? (current->leftChild) : (current->rightChild) } if(temp->data < parent->data) { parent->leftChild = temp; } if(temp->data > parent->data) { parent->rightChild = temp; } } bool BST::contains(int value) { Node* temp = new Node(); temp->data = value; Node* current; current = root; if(temp->data == current->data) { // base case for when node with value is found std::cout << "true" << std::endl; return true; } if(current == NULL) { // base case if BST is empty or if a leaf is reached before value is found std::cout << "false" << std::endl; return false; } else { // recursive step current = (temp->data < current->data) ? (current->leftChild) : (current->rightChild); return contains(temp->data); } } int main() { BST bst; bst.insert(5); bst.contains(4); system("pause"); } As it stands, I would insert a single node with value '5' and I would search the binary search tree for a node with value '4' - thus, I would expect the result to be false.

  • Firefox: combine bookmarks toolbar and tabbar

    - by horsedrowner
    I am looking for a way to 'minify' the Firefox UI by combining the bookmarks toolbar with the tabbar. The easiest way I could see this done, is by simply moving the Bookmarks left of the tabs on the tabbar. I do not have the knowledge of writing my own userChrome.css styles, but it seems possible to do it this way. Another more difficult way to do this, would be by making it work similar to Windows 7's taskbar. What I mean by this, is to have a bookmark toolbar, and clicking on a bookmark would turn it into a tab, just like clicking an icon in the taskbar in Windows 7 would turn that into a 'program'. Ultimately, it comes down to this: by default, you have two toolbars: a bookmarks toolbar and a tabbar. I would like to combine these into one toolbar.

  • WIFI connection interfering with Windows Server 2003 Active Directory domain. (How to debug?)

    - by Vinko Vrsalovic
    RELATED: This question has led me to ask this one. I had to change our unnamed crappy ADSL router to a crappy Comtrend CT-5361 WiFi router, now every WiFi connection to the domain doesn't work correctly: Joining the domain is impossible (see related question) Logging into the domain takes ages Authentication usually fails Question: How to debug this and pinpoint the exact problem? I have no enough knowledge on either WiFi networks or on Active Directory to know which connections are made at which stages nor how to check what's happening at the wireless level to compare what should happen to what is happening. I'm looking for resources to learn what should be happening and tools to detect what is actually happening (I expect a sniffer should be enough, but if there are better, more specialized tools, that'd be great).

  • Point IP to site for testing before delegation?

    - by cosmicbdog
    I'm migrating to a new server and would like to test before redelegating the domain over. I have some familiarity with setting up apache virtual hosts, but limited knowledge. How can I go about setting this up? My server already has a domain delegated to the server, and the IP by default has been setup to point to that. I've been told I can just add an entry to /etc/hosts/ which I haven't been able to understand what I can add in there to make this work. Any pointers would be greatly appreciated!
