I’ve been a beta (actually even pre-alpha :P) user of Woopra for a while (one of the first, if not the first), so it’s now time to pay my dues by posting a video about it, the video was made with intent to be modified (some editing and adding step by step explanation) and placed on the Woopra demo page but due to lack of time it stayed as scrap and in the meanwhile newer version of Woopra got released and therefore I decided to post it before it becomes totally useless

If you haven’t heard of Woopra yet, “Woopra provides real-time stats delivered via a revolutionary client-server application, and includes unique features such as the ability to identify and chat real time with visitors to the monitored site. The beta version of Woopra was quietly unveiled to a select audience of 200 at WordCamp Dallas, but news rapidly spread to over 2 million as buzz began to grow.”

Enjoy!

For those interested in an invite to Woopra, I have a small challenge, download the high quality video from Vimeo (on the videos page) and edit it. The best edit will receive an invite!

The following tutorial illustrates how to install and run a Squid proxy server.

First off, a little info about Squid, Squid is a fully-featured HTTP/1.0 proxy which is almost (in progress) HTTP/1.1 compliant. Squid offers a rich access control, authorization and logging environment to develop web proxy and content serving applications.

You will need the following programs installed. ‘openssl’ ‘pam’ ‘perl’ and any ‘cron’ daemon preferably dcron. A recent gcc version is also needed.

Installing Squid:

First you need to download the following source tarball.
Open a terminal window and cd to the folder where you downloaded the file
run: tar -jxvf squid-2.6.STABLE14.tar.bz2 && cd squid-2.6.STABLE14

The next step is to run the configure script.

./configure –prefix=/usr –datadir=/usr/share/squid \
–sysconfdir=/etc/squid –libexecdir=/usr/lib/squid \
–localstatedir=/var –enable-auth=”basic,digest,ntlm” \
–enable-removal-policies=”lru,heap” \
–enable-digest-auth-helpers=”password” \
–enable-storeio=”aufs,ufs,diskd,coss,null” \
–enable-basic-auth-helpers=”getpwnam,YP,NCSA,SMB,MSNT,PAM, multi-domain-NTLM” \
–enable-external-acl-helpers=”ip_user,unix_group,wbinfo_group” \
–enable-ntlm-auth-helpers=”SMB,fakeauth,no_check” \
–enable-delay-pools –enable-arp-acl –enable-ssl \
–enable-linux-netfilter –enable-ident-lookups \
–enable-useragent-log –enable-cache-digests –enable-referer-log \
–enable-async-io –enable-truncate –enable-arp-acl \
–enable-htcp –enable-carp –enable-poll –with-maxfd=4096
Then run ‘make’ and hope for the best.
After it is done compiling, type ’su’ then enter your root password and run ‘make install’

I’ve been cleaning my laptop today, and came along a project I did for my Parallel Programming course, I’ve never published this because the code was never completed as I lost interest, the challenge was the idea and the concept, anyone can write a piece of code but few people can come up with innovative ideas!

I came up with the idea of writing a PHP library which will make my multiple servers work together in running a certain job, back then I had access to around 5 shared servers, 3 were mine, and 2 were from friends… As an example, I ran Monte Carlo using this concept. One server was the master, the other 4 were slaves. The master sent the jobs to the slaves, the slaves got random numbers from random.org, calculated the integral, and sent the results back to the master. Once the master received all the results, it calculated the average and outputted the result. This was just a simple example I did to prove that my idea worked…

Level: Beginner (coder)

This is a small tutorial which will teach you how to upload files using a C# client application to a server running PHP.

We’ll call the PHP script “upload.php”, this is what it should contain:

<?php
$uploaddir = ‘upload/’; // Relative Upload Location of data file

if (is_uploaded_file($_FILES[‘file’][‘tmp_name’])) {
$uploadfile = $uploaddir . basename($_FILES[‘file’][‘name’]);
echo “File “. $_FILES[‘file’][‘name’] .” uploaded successfully. “;

if (move_uploaded_file($_FILES[‘file’][‘tmp_name’], $uploadfile)) {
echo “File is valid, and was successfully moved. “;
}

else
print_r($_FILES);
}

else {
echo “Upload Failed!!!”;
print_r($_FILES);
}
?>
