how to check domain mx records with nslookup

Hi,

So I have this client whom recently moved to Google Apps and I wanted to make sure if she has setup her mx records properly for her domain as she complaining about the email issue. Thus I thought it could be useful to post this quick tip here.

Lets get to the job, if you are linux open your Terminal and if you are on Windows launch Command Prompt.

You first need to launch nslookup tool by typing “nslookup”. Then you will need to tell nslookup to look for mx records by giving it “set q=MX” option, and in the end type the domain name you want to be checked.

So an example of the whole process will be :

 

Who is crazy? me or everyone else?

Did this every happen to you that everything that is happening around you looks crazy and insane? Things people are doing and subjects they are talking about? This often happens to me that I’m watching their lips moving and talking but I hear no voice, I do hear that as some noise and all that is in my mind is “What’s up with him?” lingering.

You’ll wake up and go to university taking a useless subject or what they called “Computer Systems Management” which is more about how the heck some company is going to success (I have no idea on how it relates the term of Computer Systems Management). The lecturer asks the class if you are familiar with this term and you all answer no, and he gaves 20 minutes of time for you all to look for it in the freaking internet and yet you are haring all these and thinking with yourself “What the heck are you talking about? Aren’t you there to teach me these instead of asking me to look for them myself?”.

That stupid class ends and all you remember is you are sitting in the bus while having your head stick to the window looking out while there is some hard and heavy song playing in your earphones and the feeling that you are somewhere between them, you nor see what is happening outside the window, it is kind of similar to the old silence movies from Charlie Chaplin and once you are about to get think about these the bus brakes will alarm you that hey, it’s the end of station, you have got to walk the rest of the way. Walking on those bumpy ground of so called city of Kuala Lumpur to reach my place, I don’t like to call it house, nothing there feels like a house, it’s more of a cage, something to lay down and recall all the memories of the day and call them off with a single smoke.

there is this rain, something good that can makes you stare, right out at the sky and thinking of all the things you missed earlier today. Your phone is ringing, it’s your angel of death, or so called your boss. why is my website is not working? Oh great, now you have to explain about how the heck rain can causeit, he is saying this that why I can access other websites but not only mine, and you say you’ll fix it in a while. you can’t even enjoy the rain, cause it’s all crazy. you might think I’m crazy after reading this, but what if it’s me who thinks you are crazed cause you actually read this?

 

Broken fonts in Google Chrome

Capture2 300x242 Broken fonts in Google Chrome

Only after Google Chrome on my computer updated itself to it’s latest stable version which is “Version 38.0.2125.101 m” I started noticing that some issues with fonts on websites I daily use! most of the websites had this ugly time new romans looking font on them while their css styles in the inspect element was showing the font addressing in styles is fine!

but seems it’s not only font’s that is being broken, I could not see some contents which were in Persian properly too, it seems the new version of Google Chrome somehow messes up with the Encoding of the Page!

At first I thought it is some plugin update or something that caused it, you know chrome is too friendly to badwares of developers who inject ads and other extras to pages without your authorizaiton through plugins, thus I disabled all the plugins but I found there is no chance for a fix! I even reset all the settings I had on my chrome!

I found out this issue is fixed on the Canary Version of chrome which is  basically the next upcoming version which is still under it’s final test.  So it’s clear this issue will be fixed on the “Version 40.0.2184.0″ of chrome as the current latest canary is stating it in it’s about page!

By the way I suggest you all to check out Opera too, I’m an extremist Opera lover! I’m using chrome only for having different session on some websites! icon biggrin Broken fonts in Google Chrome

I become a panda, an elephant and a blogger

as a part of change every time there is an exam coming for me I promise myself to start studying like a first class student and finish everything up the night before exam and go rock it, but my 23 years life experience shown that I can never achieve that in the frame I want it to happen, when there is an exam coming I start loving to sleep and feeling tired the whole day, I start feeling hungry everytime I open my slides and I also start feeling like posting something on my blog like a pro-blogger. damn it, I should straight my mind and get back to that Artificial Intelligence subject. it’s a killer task to memorize all those stuff about expert systems, robots and history of them.

wish me luck people!

why multiple updates appear at the same time on Google Play?

It always was a question for me that why application updates on android phones comes together in bulk? it has been like this for me ever since I started using android on my HTC ChaCha. Suddenly Google play shows the notification that some updates for some apps are available, but it never happens for 1 app only, atleast 3 app are involved in each Play Store update notification.

Have you faced the same thing? do you know the reason? if you do then leave a comment so me and other users may know too!  icon smile why multiple updates appear at the same time on Google Play?
