What if logic isn’t actually all that logical?

Logic, science, reason, all of it is what? Rules that always hold true for everything that they are defined for. But who really defines them? We do. Who comes up with them? We do. And what are they based on? Observation.

I remember, as a kid, reading an article in my native language, titled “What if there was no Sun?” and it, as you can guess, was full of stupid stuff like “pitch black, ice cold, nobody would survive for any more than … e.t.c.” While I was reading it, I couldn’t help but wonder why a world without our Sun would ever have any life-forms that need the sun to survive? Or why the humans on such a world would not be used to not having a sun and thus be optimized for survival in such harsh conditions.

My point? We believe logic is absolute. Maybe it is, but only for our world. We know that if we pull at a free movable object, it would move towards us. But for all we know, there could be a world out there in which doing so would result in that very object moving away from us. That sounds illogical, stupid, and inconceivable but if it happened all the time in our world, it wouldn’t be.

We believe that we can make deductions using reasoning, but how reasonable would that be when that very art of reasoning itself is a set of deductions based on observation. What about observation? Do we even really see our world as it is? We don’t even know if we all see the world the same way. A really narrow range of the electromagnetic spectrum is sensed by our eyes and is used by the brain to form an image. This is literally akin to reading a detailed book and imagining the events and the characters. Using this analogy, we can tell that while the image can be extremely detailed, it will still be limited by the amount of information it is based on. Imagine if our ears were so trained that we could, in the absence of light, form images and see using sound. Is that inconceivable? But what really is the difference between the ear and the eyes? Both sense and interpret waves with the help of the brain. If we could see the rest of the electromagnetic spectrum, we would have a much smaller list of opaque materials than we currently do.

This does of course suggest that it doesn’t matter if the science and logic we so rely on is limited by our observation as long as it holds true for our observable world, but the idea was the very fact that it would be just limited to our observable world. This is kind of like how we wouldn’t be able to tell if there were any more-than-3-dimensional-beings out there observing us right now because we can’t perceive or observe more than 3 dimensions.



Linus on C++

C++ is a horrible language. It's made more horrible by the fact that a lot 
of substandard programmers use it...
In other words, the only way to do good, efficient, and system-level and 
portable C++ ends up to limit yourself to all the things that are 
basically available in C.
In general, I'd say that anybody who designs his kernel modules for C++ is 
 (a) looking for problems
 (b) a C++ bigot that can't see what he is writing is really just C anyway
 (c) was given an assignment in CS class to do so.

Feel free to make up (d).

Spoiler song lyrics in “Amazing Spiderman 2”

I was watching this video, and below it I found this comment:

irishdancingchicken: (Possible spoilers) Listen to the lyrics: “I’ll shut down the city lights,” like Electro did. “When enemies are at your door, I’ll carry you away from war” – he tried to. “Your hope dangling by a string” = her life literally dangling by a string/web. “I’ll love you long after your gone” – he does. Doesn’t matter if you don’t like the song or artist, the filmmakers knew what they were doing when they put it in there.


Richard Parker owned an Ericsson Chatboard CHA-01

I was doing some math when I, for reasons I can’t recall, remembered that scene from “The Amazing Spider-man 2” in which, among a number of other things, there was a scientific calculator on the floor of Peter’s room. Interested to know what model it was, I googled it and landed on this post . The author identifies it as the “HP-48GX or a closely related model.” 

When I looked at the pictures again, however, I realized that the calculator wasn’t the only interesting artifact among Parker’s possessions. My eyes fell on this thing here and with a jolt I realized that I happen to own one of them.


This thing, which Lucas Allen — the author of that post —  took to be a Palm PDA, is actually an Ericsson Chatboard CHA-01, a small portable QWERTY keyboard that allowed for some decent and fast typing in the old days. Back then, everyone wanted to have one of these. Richard Parker, being a scientist and doing some really sick work probably had to type long emails and messages and this would have been one of his essentials while travelling.

It also makes sense because it’s a Sony movie and they would of course focus more on showing the characters using a bunch of their products instead of focusing on producing a good movie that fans can appreciate.


After all this time? Always

Alan Rickman, the English actor, well known for playing Severus Snape in the Harry Potter movie series, passed away at the age of 69 today. They say he had cancer. (No I don’t know which cancer it was,nor have I got any idea about how long he had had it and how much people knew about it. )

Being one of those that hate Snape during the first 6.7 books, and at the end can’t help but forgive him, and also one of those who have seen Rickman as Snape for so long that they can’t see him as anyone else, (he did, after all, make a great Snape,) I feel strangely sad about the news. Still, I don’t plan to write an essay. I’ve said what I had to say.

When I’m 80 years old and sitting in my rocking chair, I’ll be reading Harry Potter. And my family will say to me, “After all this time?” And I will say, “Always.” – Rickman.


Using two routers to extend a network – Part 2

The goal: Create two separate networks, each with its own router. Both routers will have different security and SSID, while the WAN settings of A are configured to connect to the internet while B, being a subnetwork of the first, will connect to the internet through it.

Now the thing is that the LAN and WAN IP addresses can not be in the same subnet, so here’s what I did. I changed the subnet of A from to .. Also, I changed to IP Adress to That’s all the config you need to do in Router A, assuming it is already configured to connect to the internet.

Now get an Ethernet cable and plug one end of it into any of the LAN ports (some reccomend the first) in A, and the other end into the WAN port of B. Login to it’s portal.. yeah it’s at Though I don’t see why dynamic shouldn’t  work, but since it didn’t for me, let’s assume it won’t work for anyone else. Select Static IP in the startup wizard and you’d be greeted by a number of blank input-boxes.  Fill them in as follows:

IP Address:

Subnet Mask:


Primary DNS Server:

That ought to do the trick. You might want to do a reboot, but that’s not always necessary.


Using two routers to extend a network – Part 1

Umm, yeah, so let’s get to it. What was the first interpretation? oh that’s right, Router B to act as a wireless access point for A.

So, A has an internet connection and B has to be connected to it via a cable and configured in such a manner that the connected devices automatically connect to either of the two devices with the best signal as you move about, and as B is acting as an access points, all data B receives and sends would of course need to be sent to and received from A. (Pardon me if something I’ve written doesn’t seem correct, I’m merely a noob and explaining in terms your grandma could understand.)

This was actually pretty simple, so I’d just list the steps leaving out the screenshots.

  1. Get an ethernet cable and insert one end of it into any LAN port on A, and the other end into the first LAN port of B. (actually I’m not sure if it has to be the first port or not.)
  2. Login to the web interface of B and set the SSID, i.e the name of the network, and the security settings of B to be the same as those of A. e.g. if A is called “narlges” and it’s using WPA, with passphrase “flutterwacken”, then you need to apply the same settings on B.
  3. Making sure that both A and B are in the same subnet, change the LAN IP adress of B to something other than that of A. So if the IP of A is, then you can set B to 192.168.0.X. Basically X can be any number between 0 and 255 except 1 as it is being used by A.
  4. Disable DHCP on B as it won’t be assigning IP addresses and all.
  5. Other wireless and radio settings like channel and all need to be the same too
  6. Reboot both routers?

And basically that’s it.


Using two routers to extend a network

I have recently been faced with this challenge, partly for learning, as it’s kind of an enthusiast thing and partly because I might actually need to to that in the near future. Since the title might seem a bit vague or ambigous to some, let me first make a bit clear exactly what it is I’m after. How about we start by listing interpretations? (My goal and the whole point of all this can be seen to later.)

Router A= TL-WR841N, and this one’s configured to connect to the internet using PPTP

Router B = Tenda W268R,

  1. I have two routers, and I want B to act as a wireless access point to extend it’s range.
  2. I have two routers, and I want B to have a LAN of it’s own, with A as a gateway providing access to the internet.
  3. I want to do either of the things listed above over a wireless bridge.

Let me say this much. I am a newbie. I’m not much of a networking guy, nor do I really know how this is going to work. I’m simply Google-ing and experimenting.

In the next few posts, I will explain what I have tried and what was the outcome.


Upgrading from Ubuntu 13.04 to 14.04 LTS

Those of you who didn’t bother to upgrade to 13.10 might be having trouble upgrading to the latest LTS… Yes you can not perform an “upgrade” but the word merely refers to the process where you upgrade using the updater tool just like you would update chrome or any other app while continuing to use the computer generally.
It doesn’t at all mean that if you are willing to save your files and settings, you have to upgrade first to 13.10 and then to 14.04. No.. despite how ridiculous it may sound, some did consider doing so.
All you need to do is download the ISO from the site, burn it onto a drive and boot, just like you would for a clean install. Start the installation process until you reach the part where it’d actually prompt you, and state that a previous version was found on this computer. You’d be presented with a number of options, one of which would be to upgrade from 13.04 to 14.04 LTS while preserving settings and files where possible.


Scientists claim that the Quantum theory proves that conciousness is moved to another universe on death?

“.. there’s a multiverse. In one you are married to your wife, in another you are married o another woman, in another you are married to a a man.. ” – Jason Statham, The One

Robert Lanza, who’s been stated as the 3rd most important scientist of the world by the Times magazine is the guy behind, and most directly responsible for this claim..

Though, not everything is to be believed just cause you read it over the internet or just cause some scientists claim that its true… It’s a highly controversial topic and might attract criticism from people of various religions for being in conflict with beliefs.
Plus, the thing itself does sound rather ridiculous too..
