Facebook at Work as Intranet

I kind of like status update boards as a concept for an Intranet much more than a “portal” or “brochure website”. For example customer I have been working recently has intranet that is default starting page on the corporate machines. On this particular “static” website by far the most popular page on that Intranet is lunch menu, then on distant followers pages like password for guest WIFI etc…
Another customer I have uses SharePoint as Intranet. This portal is maintained by corporate communication with standard marketing jargon. Neither of these Intranets gives employees any way to interact except perhaps a comment field in the news. I have never really been big fan of Intranet sites. Even though back in 2001-2003 I was building Intranet / KM product. My disbelieve for Intranets is mostly because they simply don’t seem to work as intended. I think where Intranets go wrong is when they start to listen requirements from all stakeholders. Then they end up something that is completely unusable Microsoft Sharepoint solution. Just because “Intranet of course has to have granular rights and it should be configurable in the browser”.
But I do think Intranets could work if Intranet would be thought as flat organization instead of rigid departments and groups. Don’t get me wrong, I think security should be there but why not having it like a social network. One service that I am looking forward to test it is Facebook at Work.
groups

This “facebook wall” where people could post whatever they want it would make the site more alive and certainly more relevant. Perhaps by default employee is subscribed to all departments but on time s/he could filter her feed list with only things that she thinks is interesting to her personally and professionally.

There are few other functionalities in Intranets that are must have features like a file share and knowledge base. With knowledge base I mean what HR writes like guides etc. that is occationaly visited. Often this is regarded as wiki or simple pages. Then there is also file share that is a place to share docs. Usually, these are made way too complicated (I am thinking you Sharepoint!) because that is what is “requirement” but really it does not need to be like that?

Learning rsync

rsync_logorsync is a widely-used utility to keep copies of a file on two computer systems. It is commonly found on Unix-like systems and functions as both afile synchronization and file transfer program. The rsync algorithm, a type of delta encoding, is used to minimize network usage. Zlib may be used for additional compression, and SSH or stunnel can be used for data security.

How to use ‘cp’ command to exclude a specific directory?

I found rsync when I was trying to copy all files except “x” and “y” files and directories. You are able to do that as following:

Notice that you can add many –excludes like:

Found some great samples by Ramesh Natarajan I have copied few below with a link to more samples.

Example 1. Synchronize Two Directories in a Local Server

To sync two directories in a local computer, use the following rsync -zvr command.

In the above rsync example:

  • -z is to enable compression
  • -v verbose
  • -r indicates recursive

Example 2. Preserve timestamps during Sync using rsync -a

 

rsync option -a indicates archive mode. -a option does the following,

  • Recursive mode
  • Preserves symbolic links
  • Preserves permissions
  • Preserves timestamp
  • Preserves owner and group

Now, executing the same command provided in example 1 (But with the rsync option -a) as shown below:

Example 3. Synchronize Only One File

To copy only one file, specify the file name to rsync command, as shown below.

Metric decimal system of measurement

In metric, one milliliter of water occupies one cubic centimeter, weighs one gram, and requires one calorie of energy to heat up by one degree centigrade—which is one percent of the difference between its freezing point and its boiling point. An amount of hydrogen weighing the same amount has exactly one mole of atoms in it.

Explaining object-oriented programming

Here, in an excerpt from a 1994 Rolling Stone interview, Jobs explains what object-oriented programming is.

Jeff Goodell: Would you explain, in simple terms, exactly what object-oriented software is?
Steve Jobs: Objects are like people. They’re living, breathing things that have knowledge inside them about how to do things and have memory inside them so they can remember things. And rather than interacting with them at a very low level, you interact with them at a very high level of abstraction, like we’re doing right here.
Here’s an example: If I’m your laundry object, you can give me your dirty clothes and send me a message that says, “Can you get my clothes laundered, please.” I happen to know where the best laundry place in San Francisco is. And I speak English, and I have dollars in my pockets. So I go out and hail a taxicab and tell the driver to take me to this place in San Francisco. I go get your clothes laundered, I jump back in the cab, I get back here. I give you your clean clothes and say, “Here are your clean clothes.”
You have no idea how I did that. You have no knowledge of the laundry place. Maybe you speak French, and you can’t even hail a taxi. You can’t pay for one, you don’t have dollars in your pocket. Yet I knew how to do all of that. And you didn’t have to know any of it. All that complexity was hidden inside of me, and we were able to interact at a very high level of abstraction. That’s what objects are. They encapsulate complexity, and the interfaces to that complexity are high level.

Object and Array literal in JavaScript

This post is mostly for my own reference as I seem to keep messing this up. :O

The basics

{} is an object literal

 

[] is an array literal

 

properties can be accessed via . and [] notation:

 

Object literals can be set using literal values or strings:

 

 

Cloud Compute uptime

disconnect

I have been hearing some criticism on Azure reliability lately. So, I decided to check out if anything I hear has any base by trying to compare Azure VM’s against other IAAS’s and I was quite surprised instability of Azure when putting side-by-side with its competitors.

Even though I don’t use Google Compute Engine personally. I decided to compare it together with EC2 and Azure VM’s since it is among one of the most popular ones.

I think Azure is very nice platform, I use it daily (Office 365 and VisualStudio.com) but they’ve effectively priced me out every time I need to get a server up quickly. Then I always end up to EC2 (Which I like also) but I would like to run some servers on VM’s. Just to get first hand experience how is it to operate real stuff on their beautifully designed Azure Admin.

Disclaimer: I have not used in-depth research on the topic. This is just what I found out by looking numbers from CloudHarmony. If you have more in-depth knowledge on the topic. Please comment the post. I would love to hear it.  

Here are the numbers from CloudHarmony

1 Year Global Uptime

You can see that average downtime has been 3.3 hours per region where as EC2 had 14 minutes. But if you are running IAAS on here it makes much more sense to look about the uptime of the regions (datacenter). As a sample I put up Europe here to see same numbers from 1 year on Europe data centers.

1 Year Europe Uptime

This is actually looking worse for Azure and Google where as very good for Amazon.

If however you are planning to run IAAS on some of these cloud services, do your own research and include the specific services your VM’s are running. I recommend also paying close attention to the monthly/quarterly uptime trend in addition to aggregate uptime numbers.  I would also recommend building your application/infrastructure  cloud agnostic so you are not married to them (yeah, easy to say…).
