Let’s say you have some server running around the world.
I bet most of it doesn’t really need an GUI to be running all the time.

The least you may need is only a terminal access to it.
Which is sufficient if it is running at runlevel 3.

Here is how you can specify the default runlevel on the CentOS server.
It may save some resource during runtime.

In CentOS default runlevel can be set by editing /etc/inittab
The list of runlevel is as below:

 
# Default runlevel. The runlevels used by RHS are:
#   0 - halt (Do NOT set initdefault to this)
#   1 - Single user mode
#   2 - Multiuser, without NFS (The same as 3, if you do not have networking)
#   3 - Full multiuser mode
#   4 - unused
#   5 - X11
#   6 - reboot (Do NOT set initdefault to this)
#
id:3:initdefault:

Just ensure not to set it to runlevel 6 or 0. Otherwise it would be in rebooting or just halt endlessly.

Once done editing.

kill -HUP 1

that’s it.

When there is 99 things goes wrong, we tend to think we’re doomed. Haha. That’s what happened most of the time.

#AnakAnakMalaysia

However, my recent event regarding the above make me think otherwise. Eventhough things seem to be upside down, there are all with different priorities. As long as it’s not the most crucial or possibly fatal if fail. it’s gonna be alright anyway. Why?

Let me tell you an example.

let’s say here is the list of things that goes wrong for the day :

1. house messed up
2. laundry not done
3. dishwasher not working
4. washing machine cable got eatean by mice.
5. train having technical problem
6. late to arrive to the office.
7. kids throwing tantrums
8. car cannot even start
9. servers are having error codes that yet to be solved

..

and compared to one thing got right:

1. baby sitter called said baby is doing OK.

so, perspective wise , our perception of things goes wrong may have been thrown out of balance if the above is reversed.

That’s being said, I guess there are way too many reasons to be grateful instead of being the opposite.

thanks for everything.

Fedora 26 has been released.

Head to https://getfedora.org/en/workstation/download/ to get your ISO.

Here is some screenshot from the Live Workstation ISO.

Good news, the SSHD daemon is disabled by default.
Need to manually turn it on to access via SSH. 🙂

The new MRT line from Sungai Buloh to Kajang line started 17 July 2017.

This sign shows which station are reachable from Muzium Negara station.

To get there is a bit tricky look above your head for the signage, it is linked to KLSENTRAL station but need to walk from one to another escalator.

Surprise, the first day, FREE ride only up

to Muzium Negara. it just end at Muzium Negara.

Let’s say we want to reach somewhere at point Z.
And our current location is at A.

Somehow we first must get ourself to point B, then C,D,E,F
and eventually final step, getting from point Y to Z.

If we know we have about 5 years to reach point Z,
would it be reasonable to stuck at being getting from A to B for more than 3.5years. ?

The point is, whatever you plan as your main destination.
Just focus on getting to the next point at one time.

The whole route may be different from one and another.
It may also seem unreachable at one point.
But,what we can do is to focus all our energy on the very next first step.
Eventually we will get moving and stay motivated.
Thus bring us closer to our destination.

I was reminded by someone of the following:
“Mostly of what most people know is not worth knowing.”

Focus on what we values most and filter out the rest.
Just don’t waste our life, our energy, our resources fighting and arguing on trivial matter.

Most of the stuff that matters, are being ignored by most of people.
Be different.

Let’s see you want to download a series of file from somewhere.
Which is having sequential filename.

This can be easily done with a shell script.
such as below:

for i in {1..113} do echo $i done

for i in {1..113} do echo $i done

while am at it, why not make a PDF file out of the images file.
this may require ImageMagick to be installed first.

yum install ImageMagick -y

So, the final script would be something like..

Early in the morning as I walking to the office, I was wondering it would nice for the day if I got latte drink.

Later that day, I went out to have lunch with others.
As the time come, they got latte the in the menu..
Straight-away ordered it without any second thought.

Little that I know, the conversation during that lunch meeting lead to ..
“How many hour do you sleep a day ?”.
The CEO answer was “..about 4 hours a day”

I guess that maybe a new normal for anyone at this position. 🙂
With all the thing on his plate, I don’t think a decent mind would tolerate anything less.
“We got to constantly improving ourself or eventually we became dinasour.”
Coincidentally, those similar wording also come out from our beloved
Prime Minister too.

That’s didn’t stop there.
Eventually after dinner that day, my wife opened up the fridge and give me this.
“…A latte!”

Snapped a photo out of excitement..

posted to fb, later got comment in ‘family WA group’.

.. totally unexpected one:

“whose hand got wrinkles all over ?”

I rest my case for the day.. haha!

While digging into Amazon AWS documentation for HTTPS or SSL setup, I bumped onto the following services from Qualys SSL Labs . Because I wanted to test how secure is the SSL being implemented on my webserver.

It does exactly what it says. Verify and grading the implementation of SSL on webserver.
Here is the output.

Not bad. Thanks to CloudFlare.

Amazon have been offering FREE Tier service for a year.
You can now grab using your own account without the need to setup an organization first.

You can see the detail of offering at https://aws.amazon.com/free

These are few recipes that I can gather for this purpose.

1. Register your own domain. Point it to a manageable DNS server.
I personally use namecheap. But there are also Free service provider such as Hurricane at https://dns.he.net that offer the similar capability.

2. Once the domain registered and propagated properly.
You should at least able to receive email on this domain by now.

3. Register AWS free tier with your new domain’s email.
