Today, I noticed that my server's RAM and swap space usage is above 50%. That's bother me, I don't want my server goes down like before due to high usage of memory. I want to doubled my swap space since I don't have any money yet to upgrade my RAM (+$20/mo.).
Since this is done without rebooting, we will add more swap space by creating one swap file (not swap partition -- partitioning need server reboot/remount). My initial swap space is 1024MB (1GB) and I want to add more 1GB.

So, here's a simple step to add a swap space:
[1] create a new zeros file using dd command, since I'm adding more 1GB, the count parameter on dd should be 1024*1024=1048576 , here's the dd command (I named new swap file to /swapfile1):

[root@ns1 /]# dd if=/dev/zero of=/swapfile1 bs=1024 count=1048576
1048576+0 records in
1048576+0 records out
1073741824 bytes (1.1 GB) copied, 45.5356 seconds, 23.6 MB/s

[2] zeros file has been created, now we make it as swap file:

[root@ns1 /]# mkswap /swapfile1
Setting up swapspace version 1, size = 1073737 kB

[3] make it on!

[root@ns1 /]# swapon /swapfile1

[4] check it using free

[root@ns1 /]# free
             total       used       free     shared    buffers     cached
Mem:       1026788     940420      86368          0       4096     363916
-/+ buffers/cache:     572408     454380
Swap:      2097136     803060    1294076

Yup, it's activated now.. you may add entry on your /etc/fstab so it will automounted when your server is rebooted, add this line

/swapfile1              swap                    swap    defaults        0 0

That's it! Have fun with your server!

What?!
Yeah you hear it right.. this is just a fun project for me to lift the stress from work. It's quite challenging for me: how can we upload video from Youtube to Megavideo. Honestly, this matter rise up on my mind because I have an account on Megavideo but never upload any video to it. So, since I'm not a video maker nor video shooter, I begin to think to use Youtube as my source of video. You know, there's already a lot of video on Youtube, so, I will take that advantage to upload it to my Megavideo account.

Why would you do that?
Well like I said before, I've never used my account to upload. You know, on Megavideo, we're rewarded when somebody watch our uploaded video. Why would user watch the video on Megavideo rather than Youtube? That's because they can download the video.

So, where's your work?
Here it is: Youtube to Megavideo .. yeah... it's simple, sometimes the upload is failed caused by wrong input (usually on Youtube title and description). Megavideo, sometimes, also failed to convert the video that already uploaded.

That's it! You may try it, but I didn't guarantee the result... :p

OK, I got a few free time to write this simple report. As you may know, this month Google has updated it's PageRank.
This time I'll give you my sites progress on PageRank update. Let's start with this blog.

• This blog has doing well despite it lacks of regular posting. The PR has gone up from PR 3 to PR 4. I'm happy with it, but it come with responsible to keep my blog updated and maintain the post's quality
• Advanced SEO Statistic - vRank.org : hasn't doing well, the pagerank is stuck in PR 2. Well, I think it's fine since I've never do link building for this site
• Multi-social networking status updater - JustSayItOnce.com : has doing very well, it jump from PR 0 to PR 2. The promotion is very minimal that's why I'm so surprised that it went so well. The Alexa ranking is also very poor (12 million+), I'm curious why Google decide to mark this site to goes up.
• AJAX Reverse IP/DNS Look Up, WHOIS and Browser Info - reverse.vrank.org : a subdomain of vRank.org has gone up from PR 1 to PR 2. I'm happy with it since I'm using this site for personal use and no immense promotion.
• Devzed main site - www.devzed.com : stay on PR 0. It's fine since it's a dummy blog.
• Friendster private profile viewer - fs.devzed.com : stay on PR 2. It's fine it's "hacking-like" kind of site. But the traffic is down, maybe it's because I place CPALead survey on it.
• Simple SOCKS5 proxy checker - prox.devzed.com : up from PR 0 to PR 1. Ha ha.. this is surprising.. this site has never been promoted (except posting in this blog). This site has mean to be a demo for somple SOCKS5 proxy checker. I think Google valued it as serious site.. LOL!
• Youtube downloader - yt.devzed.com and piyeto.info : this made me sad, it goes down from PR 1 to PR 0. Again, this must be because I placed CPALead codes that drive away visitors and also I sell the script so there's a lot of competitors out there.
• Kaskus badge server - ngask.us : This site is my contribution to Kaskus.us - The Largest Indonesian Community. It goes up from PR 0 to PR 1. Nice!

That's it all. How about yours?

PS: if you want to place a Pagerank badge, put this code:

<img src="http://www.vrank.org/pr.php">

on your site. It will automatically show your website's pagerank. Or if you want complete SEO statistics, use this code:

<img src="http://www.vrank.org/badge.php">

You can see the example result on this blog (on left sidebar)

This is another lazy post.. I'm copying it from my DP thread.
I'm creating new site for downloading from MegaVideo that support download manager/download accelerator.

Site's URL:
http://www.megavideodownloader.com

You can insert the MegaVideo URL on the provided text box or you can directly accessing it by modifying MegaVideo URL.

Original Megavideo URL:
paste this URL to your browser's URL:
http://www.megavideodownloader.com/?v=X0HUC7R9

The site will automatically check the link if it's valid or not(deleted).
Please do test it and let me know about the speed and the video downloaded (is it corrupted or not).
Since this script is new.. I need to know your feedback.. once I'm sure that the script is working perfectly, I'll add another server and probably adding Megaupload downloader also (depending on the traffic I get).
