I stumbled yesterday upon my first website I had created. This sure brings back memories on my old desktop PC, and keyboard sitting, and typing away at late nights 😉

On another note, it does have some useful notes on Chasen (Japanese language morphological analysis tool), Mecab, Using Python with Chasen, Cygwin etc.
Start by writing the two numbers to be multiplied at the head of two columns. Then they repeatedly divide the number in the left column by two (dropping any remainder) and double the number in the right column, writing the two new numbers immediately below their predecessors, until the number in the left column is one. Then they cross out all rows where the number in the left column is even, and add the remaining numbers in the right column, which is the desired product.
For instance, the product eighteen times twenty-three is found like this.
Programming Praxis: Russian Peasant Multiplication – The Daily WTF.
Last whole week I was stumbled by the fact that my home network with 3 PCs suddenly stopped working. None of them were able to “see” each other, except for a little while… strange.
Technically (since it is easier to describe), A, B, C – my 3 computers – could reach each other, share files, host apache, download files without any extra configuration.
Last week, however while using C’s http server from A suddenly stopped. Puzzled, I thought the machine might be overloaded, or something like this must be causing page to timeout, or apache must have hanged (does it?). But things seemed to be working OK on C, in fact top showed a load average below 1 ?
Further puzzled, I tried pinging A to C, and vice-versa. It worked… but only for a while. Pinging after a while seemed to stop. Huh?
Scourging over the Internet wasn’t easy for answer. Maybe my way of searching was wrong, but I did spent a good week trying to fish out the ping issue, then next to dig deeper to find that accessing C’s IP from outside (it already has a global ip; though dynamic, paired through dyndns to the world) worked. Now each of them – A, B, C – have no internal 192.168 ip’s, just public ip’s. What good are public ip’s if I have to access them from outside than just sitting home?
Something was wrong.
To cut short, I called the ISP, asked them if they have changed anything recently (well, I was using A, B, C sharing files for over 6 months now). My ISP reported that no such upgrade, or settings were done. Deeply mad about this situation, I chose to disable the firewall (Eset Nod32) on A, and then tryout the ping – which worked effortlessly to C, and back.
What the hell! Why did Nod32 suddenly seem to block my own A, B, C from seeing each other? ARP Poisioning? I don’t know, only thing I know is that it shouldn’t block them. 🙂
Well, atleast things are fine now. I’ve changed settings on Nod32 to Not block threat detected addresses henceforth.
