SmadAV – At a Glance
SmadAV is a local antivirus made by Indonesia youths that I’ve heard since some times ago but just now I get the chance to give it a try. Here is the screenshoot, very simple with all tools in a single modal dialog (click to zoom the pic).
The interface is likely different than any other antivirus, very simple and contains all what we need when the computer is under attack by the viruses.
Some viruses will disable access to msconfig, regedit and task manager that make us difficult to restore the computer. And SmadAV provides button to access msconfig, regedit and task manager in a single click. Cool!
I would like to say that SmadAV is made by experienced people, I mean, experienced with the virus problem. Maybe that’s why they include all the tools to kill virus in a single application. It’s like having a swiss tool knife for all your virus problems.
Although I haven’t use SmadAV on my daily basis, it’s a recomended one. They said that after give some donations, we can get a license key to unlock some more features, like faster scanning and automatic updates.
Create PDF Files For Free
I was wondering why many people still using Adobe Acrobat for creating PDF files from their documents. It’s bloated –or you can say my computer is too old– and of course expensive! Some minutes ago I’ve checked the price on their website, it costs US$ 299.
Why don’t people find an alternative PDF-maker software which is free and lightweight? I know that you can get any serial number from Internet for Adobe Acrobat to turn that pricey software into a free one. But hey, it’s like stealing from a kid’s pocket.
A few days ago –when I needed a software to convert my documents into PDFs– I found doPDF which is free and lightweight. And most of all, it doesn’t require any Ghostscript installation just like any other PDF printers.
Perhaps it doesn’t have all the features you want and requires you to upgrade to the paid version but it’s enough for me. Awesome PDF printer.
This way I thank to doPDF developer(s) for their great work.
Redirect Old URLs to New URLs
When we have a completely new website and uses different CMS, there will be old URLs that already spread everywhere on the Net. Discarding old URLs is not an option because we will lost visitors from search engines. So we must redirect all old URLs into new URLs.
Using redirect in .htaccess is great, but when your old URLs contain question mark, most likely it will fail to redirect.
Following code will work:
redirect 301 /old-url.html http://domain.com/new-url.html redirect 301 /very-old.html http://domain.com/very-new.html
But following code will –at least in my case– failed:
redirect 301 /file.php?age=old http://domain.com/new-url.html redirect 301 /file.php?age=old&id=12 http://domain.com/very-new.html
Luckily there’s 404 directive from Apache using .htaccess. We can mix the power of custom 404 page with PHP to perform this directions stuff. Here’s how to mix them up:
Create custom 404 page using .htaccess
ErrorDocument 404 /redirect.php
Then create file redirect.php with following contents:
< ?php
$req = trim($_SERVER['REQUEST_URI']);
switch($req){
case "/file.php?age=old":
$goto = "http://domain.com/new-url.html";
break;
case "/file.php?age=old&id=12";
$goto = "http://domain.com/im-very-new.html";
break;
default:
$goto = "http://domain.com";
}
header ("HTTP/1.1 301 Moved Permanently");
header ("Location: $goto");
?>
By this method, old URLs that are no longer exist are forwarded to our custom 404 page (named redirect.php) and that redirect.php will bring visitors to new URLs.
Nice, isn’t it?
