The Internet Map

http://internet-map.net

From the site:

The map of the Internet

Like any other map, The Internet map is a scheme displaying objects’ relative position; but unlike real maps (e.g. the map of the Earth) or virtual maps (e.g. the map of Mordor), the objects shown on it are not aligned on a surface. Mathematically speaking, The Internet map is a bi-dimensional presentation of links between websites on the Internet. Every site is a circle on the map, and its size is determined by website traffic, the larger the amount of traffic, the bigger the circle. Users’ switching between websites forms links, and the stronger the link, the closer the websites tend to arrange themselves to each other.

The Mythical Man-Month: Essays on Software Engineering

Over the past couple months i have been reading through the book The Mythical Man-Month by Fred Brooks.  It was originally written in 1975 but many of the concepts still apply today. I have been apart of projects which have fallen into some of the traps talked about in the book. Below are some quotes (some paraphrased) from the book (one or two from my experience) i think everyone in senior management should think about before starting a large scale software development project:

1. Never build when you can buy
2. The programming project converges more slowly the nearer one gets to the end - plan for it
3. Good cooking takes time; some tasks cannot be hurried without spoiling the result
4. All programmers are optimists and are typically bad estimators
5. Men and months are not interchangeable (in my own words:  you can not take 9 women and make a baby in 1 month just like you can't double your programming staff and expect to cut the project in half)
6. Estimating is hard due to the fact that that programmers are building something that has never been built before.  If it has been built before then you should be buying it off the self...
7. Because programmers are uncertain about our scheduling estimates, they often lack the courage to defend them stubbornly against management and customer pressure.
8. Brooks's Law: Adding manpower to a late software project makes it later.
9. Adding manpower to a software project increases the total effort necessary in three ways:  the work and disruption of re partitioning itself, training new people and added intercommunication.
10. 1 good programmer is worth 10 mediocre ones

Ubuntu Linux - Removing files based on date

A little script to remove files based on date.

This command will remove anything older then 30 days:

find /data/server/log/ -mtime +30 -exec rm {} \;

This command will remove anything over 1 year:

find /data/server/log/ -mtime +360 -exec rm {} \;

Office Communicator Server 2007 Simple Log - SQL

We currently use Office Communicator Server 2007 (OCS) and my boss asked me for a simple log of all the activity for the past month.  I thought an SQL Script would be easy to find on the internet but it wasn't so wrote my own and am posting it here:


OCS 2007 SQL - Simple Log:

SELECT MessageIdTime, uf.UserUri as [From], ut.UserUri as [To], m.Body
from LcsLog.dbo.Messages m
join LcsLog.dbo.Users uf on m.FromId = uf.UserId
join LcsLog.dbo.Users ut on m.ToId = ut.UserId
where 
m.MessageIdTime between '06/01/2012 00:00:00' AND '06/30/2012 23:59:59'

To strip out the HTML tags in Excel you start Excel's Replace (Edit/Replace or Ctrl+H) and put <*> (that is 3 characters, a less-than symbol, an asterisk, and a greater-than symbol) for your "Find what" condition and leave the "Replace with" field empty.
