Okay, I have to admit I wasn’t a big fan of functional programming languages, but looking at the benefits that it introduces, it might not be a very bad idea to put it under the microscope for a while. So, in this blog post I am going to list some of the benefits that are introduced by functional programming language. “Polymorphic Type Systems” : Functional programing languages usually lets you use functions for many types (belonging to the same class), thus making use of the concepts of generecity and tragically reducing the software maintenance costs.
I have been away for a while now but every time I think I won’t need to lay a hand on C++ or any object oriented programming language I find my self mandated to do so. So I thought It would be helpful for people like me to look at this post if they got lost and forgot some of the basic concepts. In this post, I will talk specifically about the difference between public, private and protected key words.
If you are a wirless kinda guy, you might be interested in having a look at this quick presentation. This presentation will give you an idea about: WLAN pros and cons WEP introduction WEP vulnerabilities and threats Exploiting Vulnerabilities Counter measures and best practices If that caught your interest, then you might want to have a look at the presentation below.
Okay, the difference between a layer 3 router, switch and a multilayer switch seems to confuse alot of networkers, so I decided to write this to briefly explain in a nutshell the main between both. Before starting to talk about layer 3 switches or multi-layer switches, why not briefly summarize “Switching” as in basic layer 2 switching. Before switches existed there were devices called bridges, and I will not be explaining or going into much details about what is a bridge, but here is the main differences between a bridge and a switch: A Switch is a bridge but with more than only two port.
As a network engineer you must have skimmed through millions of acronyms and abbreviations like MAC, IP, FTP, ….. and so on, they are un-countable :D. Sometimes these abbreviations mix them into a cocktail in my head, so Today I thought of re-visiting some of these abbreviations and concepts that I consider fairly important if you are considering to understand switching. So let’s start of by defining each one of these abbreviations.
“IP telephony is the Concept, VoIP is the Use” I believe this quote can serves as an answer to the Big Question, but what does this really mean ?. To answer this question lets define each term separately. IP telephony: It is a term used to describe the area of communication that is based on Internet standards like the Internet Protocol (IP). Examples of an IP telephony system include and IP Public Private Exchange (PBX).
Also this might be very easy to do, I always seem to forget it =D. Anyway, here is how: you just type cat etc/lsb-release on your terminal. That’s it =). I hope this helps, Have a good day!!
Okayy, So I spent some time trying to get ubuntu to play out .wmv files, it took me a little while to figure that out. Here is how: First you need to download an adequate player. I Personally use “mplayer” You can use synaptic manager and search for it. Or, you could download it using this command sudo apt-get install mplayer Now, Let’s install some packages from medibuntu.
Here are the brief steps of how to recover passwords on Your Cisco Router: Type show version to check on the current value of the configuration register. The configuration register is usually set set to 0x2102 or 0x102. Turn the router off and turn it back on. Within the first 60 seconds, press Ctrl+Break to exit the Boot sequence and enter the Rommon mode. In the rommon mode type confreg 0x2142.
Long time I had this question in my head, why do we subnet, yea I am being a smart guy, I am very good at sub-netting but I didn’t know why it is so crucial. Well there are many answers to that question, the most general ones are: Reduced network traffic Optimized network performance Simplified management Facilitated spanning of large geographical distances. Okay, that’s cool but still, How does it do these “bla bla written above” =D ?
