Computer clean thyself!

Thu, 22 Jun 2017 09:32:03 GMT

They say a clean desk is a sign of a sick mind. I have to admit that my mind must be as healthy as an ox because my desk is as cluttered as a teenagers mind when he looks at a playboy picture (although I have heard that playboy is not as, er, graphic as it used to be).


When it comes to computers and operating systems however, that is a different story. I will literally spend

Microsoft opens up

Thu, 22 Jun 2017 07:06:15 GMT

I knew it would happen sooner or later. There is no possible way that the closed source model will ever be a successful one for software which is integral to computer usage.


For years Microsoft denied this. They called open source software a cancer and a disease and vowed to destroy it. Well maybe not in those exact words but very similar.


Finally Microsoft

Other Dead LAN Strategies

Tue, 20 Jun 2017 23:59:52 GMT

Companies such as Bridge Communications, Ungermann-Bass, AT&T, and Wang were major players, or at least they were attempting to be.

The changes in social media

Tue, 20 Jun 2017 15:57:46 GMT

Even before the Arpanet allowed people to communicate with each other across the network there has been a social media. People for some reason just love to communicate with each other. Whether it is by the office water cooler talking about what Johnboy did to Maryjane or over the wire sharing questionable photo's and movies.


In the beginning there were things called bulletin

DEC's Networking Strategies

Sun, 18 Jun 2017 03:09:58 GMT

An important deviation from past DEC policies was extensive support for interconnection to networks and facilities outside DNA, including, in particular, support for IBM's SNA and Novell's NetWare.

IBM's Impact on LANs

Fri, 16 Jun 2017 00:11:00 GMT

Particularly in the areas of microcomputers, LANs, and enterprise networking, IBM's insistence that its customers remain "pure blue" ran against both the economic and technological developments set in motion before 1990.

Power for the people gadgets

Wed, 14 Jun 2017 06:51:59 GMT

Just about, actually I would say all, technological knick nacks and doo dads we love to wear, carry and play with need electricity to run. It is these busy bee electrons which are tirelessly working to provide for our entertainment, computational and living needs.


This power comes from several sources and for us, it starts with a plug and a wall socket. That, coupled with

Light 4j Docker Container Chassis Ideal for IOT

Wed, 14 Jun 2017 00:43:47 GMT

ResinOS and Light 4J based containers could offer some of the highest performing utilities in the IOT space.

Network History - APPC/APPN Notes Continued

Wed, 07 Jun 2017 22:26:08 GMT

In the paper, "Advanced Peer-to-Peer Networking," Joyce and Walker have offered the following characterizations of APPN and APPC:

IBM Networking Strategies and APPC/APPN

Mon, 05 Jun 2017 22:38:40 GMT

As their names imply, APPC, Advanced Program-to-Program Communication, deals with programs, while APPN, Advanced Peer-to-Peer Networking, deals with networks.

The programming life continues

Wed, 31 May 2017 16:18:30 GMT

In the previous article, I mentioned how I worked for a company which was a real sweatshop, high-pressure environment which was really not healthy for mind and soul. Suffice to say I did not renew my contract with that company.


Consequently, other companies I have done programming for have also been wildly different. Some were pretty laid back and allowed my creative juices

The programming life

Wed, 31 May 2017 15:54:50 GMT

I have been involved with computers since before I found girls interesting. The only problem is that girls never found me to be interesting but that is another story.


It was my first computer, with it's very well detailed basic programming book which taught me how to program. From there it was keying in programs from magazines, finding out why those keyed in programs didn't

What a cutie!

Wed, 31 May 2017 10:42:21 GMT

I just got an interesting mail today, not of the dead tree variety but of the live electron variety. This mail told me that the latest version of my favourite programming platform, Qt (supposedly officially pronounced "cute" but I have always pronounced it as "Q,t" and probably always will) has been released.


This in itself is not earth shattering news as Qt is always releasing

The good, bad and the ugly

Wed, 31 May 2017 06:09:39 GMT

If it wasn't for technology we wouldn't be where we are right now. It has lifted the human race to heights (literally) that have never been achieved in the history of the Earth before. The only place for humans to go now is up (again literally :) ).


Technology has increased our lifespan, our health and standard of living. It has made the world a smaller place (not literally

Fragile, wasteful technology

Tue, 30 May 2017 16:25:29 GMT

Technology is fragile. The more useful it becomes, the more fragile it is. The more things technology can do, the smaller and more compact it gets, the more fragile it is. Not only that, it becomes much more wasteful as well.


Let's take, for example, my favourite piece of technology, the computer. The computer is a wonderful piece of technology which I have been fortunate

Raising the block on the chain

Tue, 30 May 2017 15:10:26 GMT

If you have ever been into cars and I don't mean been into cars as a driver or passenger, all of us have done that. I mean if you have ever been interested in working on cars as a hobby then you would know what a block is and why it is raised on a chain.


I am not here to talk about cars but I am going to talk about blocks and chains. Blockchains for short and it is the underlying

A bit of a ripple

Tue, 30 May 2017 13:54:44 GMT

There is one thing which seems common to most science fiction, or should I say, future based, television shows and movies. This thing seems to be the lack of cold hard cash (although Quark ruins this dystopian dream with his love of gold pressed latinum).


Instead, everyone just simply gets what they want and has everything provided for their needs. You never actually

How is serverless computing changing our world.

Tue, 30 May 2017 08:22:11 GMT

Serverless computing in a way has been there for long. In an Infrastructure As A Service setup the end users are not physically managing servers, but serverless computing takes this paradigm a step ahead. It enables developers execute function using exact amount of computing resources needed.

Implementing IGMP Membership Reports

Mon, 29 May 2017 23:35:17 GMT

Because the standard specifies that the report for each host group should be delayed a random time, igmp_settimers calls function hgrand to compute a delay.

IoT, the ants of the future?

Mon, 29 May 2017 16:24:22 GMT

The ideal conditions for a picnic also seem to be the ideal conditions for ants to selflessly share your food with them. There doesn't seem to be a way to get away from them. Even in my sixth-floor apartment, the little buggers have the nerve to sprout wings and fly themselves in. So do a lot of other bugs and creepy crawlies.


As you are probably well aware there are more

The electronic lasagna

Mon, 29 May 2017 15:55:43 GMT

I am sure you have heard of the orange tabby cat (by the way, orange tabby cats are generally female, male ones are rare) called Garfield. This fat cat just loves his lasagna and let's face it. Who doesn't?


There is something about those layers of alternating minced meat and pasta just dripping with melted cheese and tomato based sauce that makes your mouth drool. My mouth

How long will your job last?

Mon, 29 May 2017 09:20:18 GMT

There is one thing which has been consistent with the rise of technology and that is that technology is created to make our jobs easier. Not only make things easier but also replace them.


It started out simply enough. Dangerous jobs were done by technology to save human lives. Household gadgets were created to make house work easier and quicker.



OSI Interoperability and Internetworking with TCP/IP

Wed, 24 May 2017 23:24:19 GMT

we saw that the interconnection of OSI standard networks generally takes place through the Network Layer by use of a relay system. A message moves from one Open System network to another Open System network through peer Network Layers.

Light Java Project becomes Light-4j on Github

Wed, 24 May 2017 00:08:59 GMT

Designed for microservices that can be dockerized and deployed within containers

IGMP: Joining a Host Group

Tue, 23 May 2017 23:49:58 GMT

To eliminate unnecessary multicast traffic on a network, hosts and multicast routers use the Internet Group Management Protocol (IGMP).

MAC Level Bridges

Fri, 19 May 2017 21:44:55 GMT

Because a MAC bridge operates below the MAC service boundary, it is transparent to protocols operating above that boundary. A Bridged Local Area Network may provide for:

Organizations Will Never Realize the Benefits of Agile and DevOps by Reading the Internet

Wed, 17 May 2017 22:12:02 GMT

What I find worse is that when you at least attempt to coach teams along this path, they sometimes will say bizarre things like: ?Um. I think there is enough stuff written about continuous integration out there on the web that we can probably figure it out for ourselves.?

Accessing Other Networks in the Early Years

Wed, 17 May 2017 21:47:35 GMT

The network operating system or other networking software could make moving from one PC LAN to another either simple or complicated.

IGMP: Translating Between IP and Hardware Multicast Addresses

Tue, 16 May 2017 22:19:11 GMT

When a host leaves a host group, it calls procedure hgarpdel to remove the ARP cache entry and inform the hardware.

The Bygone days of LAN Gateways and Bridges

Mon, 15 May 2017 22:10:52 GMT

That was the state as we grew networks through the 1990s. But these devices also disappeared into routers and switches such that it was easier to simply light up a port in a switch that was used to bridge to another switch representing another network. These sorts of devices are rarely seen today as stand-alone hardware products.
