Rival of Clout Computing – the FOG

fog_computingFog Computing is not a new concept. Like Cloud Computing, it’s just a marketing buzzword for something that’s already taking place.

Fog Computing – that takes place at the edge of the network, closer to home. That is, computing that takes place on the devices that are nearest to you – your smartphone and other connected devices that are around you. The so-called Internet of Things (IoT), or Internet of Everything (IoE).

Below article from The Wall Street Journal

The problem of how to get things done when we’re dependent on the cloud is becoming all the more acute as more and more objects become “smart,” or able to sense their environments, connect to the Internet, and even receive commands remotely. Everything from jet engines to refrigerators is being pushed onto wireless networks and joining the “Internet of Things.”

Modern 3G and 4G cellular networks simply aren’t fast enough to transmit data from devices to the cloud at the pace it is generated, and as every mundane object at home and at work gets in on this game, it’s only going to get worse.

Luckily there’s an obvious solution: Stop focusing on the cloud, and start figuring out how to store and process the torrent of data being generated by the Internet of Things (also known as the industrial Internet) on the things themselves, or on devices that sit between our things and the Internet.

Check Laptop / System Serial Number, UUID, Model Name and Number, Brand Name without using third party software

There are so many third party software available in the market to check serial number, make and model number of your laptop / computer.

However, I am sharing VB script that you can run and get same information without help of any third party software. Below is the script

set nsCIMV2 = GetObject(“WinMgmts:/root/cimv2”)
set colBIOS = nsCIMV2.InstancesOf(“Win32_ComputerSystemProduct”)
for each objBIOS in colBIOS
WScript.Echo objBIOS.GetObjectText_
Next

 

Save above script in Notepad as sn.vbs and then run it.

If you need ready made script than download it from here

there was a problem sending the command to the program / Cannot open Microsoft Excel by double clicking any excel file

You may face issue in Microsoft Excel stating that –there was a problem sending the command to the program.

ImageMany engineers do re-installation of MS Office or did unwanted RND on file and wasting time of end user and themselves too.

We don’t need to waste time on this small error, below this simple and easy solution without any re-installation of Microsoft Office software or repair anything.

Please find below screenshot for solution.

Go to Excel Option –> Advance –> General –> Ignore other application that use Dynamic Data Exchange (DDE)

uncheck above option and restart MS Excel

How speed up your Linux faster – tips

Many of my users asking about some tips to make Linux operating system faster and ease of use.
There are so many articles on the internet but big thanks theprohack that publish awesome on this topic.

1. Quick Fixes – Disable unnecessary services to make Linux boot faster
Linux comes in various flavors bundled with a lot of applications. However, most of us don’t even use Linux to its full potential. Depending upon the use of the machine, plenty of services and running programs won’t be needed. And if you are using Linux just for a desktop, then you won’t be needing the default send mail, httpd, and many other services. You can also turn off many other services if your Linux box is used as a small web server by going to Administration menu, tweaking the Services entry and deselect all of the services you don’t want to start.

2. Free up Your Kernel – Disable unnecessary kernel modules
If your Linux box is wired to the LAN/Ethernet, then you don’t need to have a wireless kernel module loaded. More services like smartcard modules and others can be disabled and the load can be taken off from the kernel. This task is a bit difficult as it requires recompilation of kernel, which is daunting for even the Linux geeks. To do this, you will need the kernel sources and then follow the standard steps for compiling a kernel. You will be having a ride through the internals of your system just disable all of the kernel modules you don’t need.

For added safety, install Bootchart which will tell you if Kernel modules are properly installed and running on your system. Not only will this give you a good list of modules, it will illustrate for you what is happening during your system boot. You can also issue the command

chkconfig –list | grep 3:on

to find out what services are running. Once you know what loading modules you don’t need, you can remove them during a kernel recompilation. While you’re at it, compile the kernel to exactly match your architecture.

3. Take Load Off Linux – Use a lightweight window manager instead of GNOME or KDE
Using a smaller window manager drastically reduces graphical boot time. Instead of having to wait that extra 30 to 60 seconds for GNOME or KDE to boot up, why not wait two to 10 seconds for Enlightenment or XFCE to boot up? Not only will they save you boot time, they will save your memory and the headache of dealing with bloatware.

4. CUI ROKZ’ – Use a text-based login instead of a graphical login
The graphical logins do two things: increase load times and create headaches trying to recover from an X windows failure. Most of Linux machines which boot to run level 3 instead of run level 5 will halt at the text-based login, where you only have to log in and issue startx to start your desktop of choice. So CUI login is the way to go.

5. The Flying Penguin – Use a lighter Linux distribution
Are You a Linux newbie? Instead of loading the heavyweight SUSE, why not try a DSL, Puppy Linux, or Gentoo? The boot time is less than the more bloated Fedora (SUSE and even Ubuntu). Loading lighter Linux distributions will save you from lot of headaches. Of the larger distributions, OpenSuSE claims to boot the fastest, but between the latest Fedora and Ubuntu, Ubuntu blows Fedora’s boot times away.

6. Get Savvy – Use an OpenBIOS
If you’re tech savvy enough to upgrade your PC’s firmware, you might consider migration to open source BIOS which will allow Linux to actually initialize the hardware as it boots (instead of relying on the BIOS). Also, many open BIOSes can be customised to meet your machine’s specific needs. If you don’t go the open BIOS route, you can at least configure your BIOS to not search for a floppy drive that’s not there or to boot directly to the first hard drive (instead of the CD drive first).

7. DHCP woes – Avoid dhcp
If you are working on a home network (or a small business network) where address lease isn’t a problem, go with static IP addresses. This will keep your machine from having to call out to a dhcp server to get an IP address. If you take this approach, make sure you configure your

/etc/resolve.conf

to reflect your DNS server addresses as well.

8. Hotplug unplugged – If you can spare it, get rid of hotplug
Hotplug is the system that allows you to plug in new devices and use them immediately. If you know your server won’t need this system, delete it. This will cut down on boot time. On many systems, hotplugging consumes much of the boot time. Removing hotplug will vary depending upon the distribution you use.
Although udev has majorly replaced hotplug. But if you’re running an older distribution, this does apply.

9. Initng for the daring ones
The initng system serves as a replacement for the sysvinit system and promises to drastically decrease boot times in UNIX-like operating systems. If you would like to see the initng system in action, you can give the Pingwinek livecd a try.

10. HackerPunk – Use a hack with Debian
If you’re using Debian, there is a simple hack you can use to switch your startup scripts to run in parallel. If you look at the

/etc/init.d/rc

script, you will see:

CONCURRENCY=none

around line 24. Change this line to

CONCURRENCY=shell

and you should see a reduction in boot times.
