6 userscripts and userstyles you should really try out

2007-08-07T12:22:00.000-05:00

A major plus that enhances the usability of a web browser is the ability to customize web pages to look and behave the way you want them to. This is done by using userscripts, little snippets of javascript code, and userstyles, their CSS counterparts. While userscripts change the way sites behave, userstyles change the way sites look.

In Firefox, userscipts can be used thanks to the powerful Greasemonkey extension. Others browsers, like Opera, come with this enhancement built-in. I already showed a quite good example of a userscript. Userstyles can be used in Firefox with the Stylish extension. Stylish, unlike Greasemonkey, cannot only modify web pages, but it can modify the look of Firefox itself.

Userscripts can also be used out-of-the-box with Opera and with an addon called Creammmonkey on Safari.

1. Pagerization

I know I've mentioned this before, but now that I've been actually using it for a few days, I just have to say, this one HELL of a userscript. It works on an enourmous amount of pages... from Google, to forums, to almost everywhere. It's just so damn useful. My next-button-clicking days are now over!

2. Combine Stop/Reload buttons

This userstyle is great if you want to go minimalistic. When the page is loading, only the stop button is showed. When it finished loading, it only shows the reload button. That's one less toolbar button cluttering your browser!

3. Greased Lightbox

This script enhances image search sites like Google Image Search or Flickr by letting you see the original image in a very Ajax-y and useful way. I can't really explain it very well -- you have to use it to understand it. It's simply amazing. However, after using it for a while, I have to say it can sometimes be a bit intrusive.

4. Folders4Gmail

This script is pretty cool in that it allows you to nest labels in Gmail -- emulating the feeling of 'folders' other mail clients have. I can't believe how I could live without this for so long!

5. GMailTo

Another must-have if you use Gmail. With this, every time you click on a mailto: link it will open a new Gmail compose window instead of the default desktop program (Evolution on Ubuntu or, God forbid, Outlook Express on Windows).

6. Bookmarklet Favicon

If you use bookmarklets as much as I do, you will find this extremely useful as well. It changes the favicon of bookmarklets to a javascript icon to make them easier to distinguish.

What about you? What are your favourite userscripts and userstyles? Which ones can't you live without? Leave a comment telling us!

Windows Downloads: Easily use ISOs with the ISO Recorder powertoy

2007-07-30T11:23:00.000-05:00

ISO Recorder is a small utility that allows you to create and burn ISO images from and to CDs and DVDs. It's extremely easy to use and is integrated in context menus of ISO files and disc drives. It's as easy as right-clicking! There is also a command-line version available.

ISO Recorder is available for Windows 2000 (command-line only), XP and Vista.

Windows Download: Make scrollwheel behaviour like Linux's with KatMouse

2007-07-30T09:37:00.000-05:00

If you've ever used Linux, you'd know that to use the mouse scrollwheel, you have to move the mouse to the window you want to scroll on, and just scroll. On Windows, you actually have to click (get keyboard focus) on that window in order to scroll.

If this annoys you every time you have to come back to Windows, there's a solution: KatMouse. This little utility (less than 400kb) allows you to do just this. To scroll something, simply move the mouse to where you'd like to scroll. No need to click or alt-tab to that window.

However, there's something else you should know about this utility: I highly recommend you disable the wheel button feature it includes (by right-clicking on the tray icon and choosing setting, going to the 'Wheel Button' tab, and setting the combo box to something different from the default Wheel Button) since this disables the wheel's normal functionality (like opening links in tabs in web browsers, or auto-scrolling).

Anyway, hope this little app proves useful.

Text Editors: Notepad++ and GVim go Portable

2007-07-23T14:37:00.000-05:00

A few days ago, Notepad++, the famous Windows text editor, was released as a PortableApp, Notepad++ Portable. I have used Notepad++ for quite some time now, and I am very glad that now I can easily take it anywhere I want on my USB flash drive.

For those of you with a more classic, Unix-y taste, there is also GVim Portable, which takes up a LOT more space than Notepad++, but includes all the amazing features of Vi withing an easy-to-use graphical interface.

Harry Potter.... over

2007-07-23T01:14:00.000-05:00

I can't believe it! I've just finished the last book in the series, Harry Potter and the Deathly Hallows. Wow. It seems so long ago, I must've been like eight, when I read the first book. I didn't know there were sequels, so I was delighted to find out that there were two more books, and four more coming. Book after book I devoured, and later movie after movie, though they never bested the books.

And now, it's over. No move books to read. Only two more movies left, which, although certainly entertaining, cannot match their printed counterparts.

It's just insane that this is over! It's been 10 long, amazing years, full of magic, adventure and suspense, packed within these 7 extraordinary novels.

But it's over now. The books I grew up with are read. No new adventures, no new magic.

Oh, well. I guess it's time to finish reading children's books and go on to the other still unread volumes in my shelf -- Brave New World, Catch 22, Neuromancer. That, and 100 Years of Solitude, a compulsory reading for my upcoming Spanish A1 IB course. Damn, I hate García Marquez. I know that's one of the most anti-patriotic things I can say to the only Nobel winner from my country, but hey, I love Jorge Franco, author of Rosario Tijeras and Paraíso Travel.

But Harry Potter will always remain in my heart, as the books that, beyond all others, introduced me to the joy of reading. I considered myself, ever when I was very young, a good reader. I read Roald Dahl and other children's authors. But never before Harry Potter did I start to seek books on my own, books I have loved and enjoyed also: The Lord of the Rings, 1984, The Lord of the Flies, The Giver, and many, many others.

For this, I want to thank J. K. Rowling, the creator of this extraordinary world. But, above all, I'd like to thank the teacher, which, back in the third grade, introduced me to this unrealistic and enthralling world of magic and fantasy; a teacher which, unfortunately, I remember nothing about, not even her name.

Trip down memory lane: Firefox 0.9

2007-07-18T02:33:00.000-05:00

You may not believe this, but I am currently blogging from Firefox 0.9. Today, whilst organizing my chaotic collection of CD-ROMs I stumbled upon an old backup disk with the installer for this quite outdated version of Firefox. This was also the first version of Firefox I ever used (well, the first version anyone used for that matter, it wasn't called 'Firefox' until this version, but this was the first version of the browser I used, Phoenix, Firebird or Firefox). Anyway, I'm extremely impressed at how awfully fast this browser is. This just goes to show how bloated software becomes with the years. Also, I think the tabs in this version are the best in the whole of Firefox history (in looks, but unfortunately not functionality). They're simply... native.

Firefox 0.9 boasts a great array of features, including:

Built-in search box
Minimalistic user interface
Tabbed browsing
Themable
Extendable
A pop-up blocker
A Download manager (which really hasn't changed at all since then)
Cotumizable toolbars

So, in escence, Firefox hasn't changed much. It's just gotten bloated. Firefox 2 is way too slow. Firefox 3 is a little faster. But the question remains: will it ever be as fast as it was in its beginings?

And don't forget: Cookies are delicious delicacies.

(Please forgive any spelling mistakes in this post: Firefox 0.9 has no spellchecker. :) )

Harry Potter 7 to be released next Saturday, finally!!

2007-07-16T21:23:00.000-05:00

I can't believe that Harry Potter and the Deathly Hallows is coming out this Saturday! And I can't believe it's finally the last book in the series!! Wow, ten years sure is a long time... I remember when I first started reading the series. Well, anyway, the journey's almost done. And as the time approaches ever nearer, everyone's making up theories and speculating about the final outcome of the series.

What about you? What are your theories? Will Hogwarts open again? Will Harry be able to destroy all the horcruxes? Will Snape redeem himself? Will Harry die to save the world?

Game Review: Frets on Fire

2007-07-16T15:26:00.000-05:00

Frets on Fire is a free clone of the popular Guitar Hero games. I decided to download it and test it out under Linux. Here are my thoughts.

Download & installation

Frets on Fire is cross-platform, so it'll work on Windows, Mac, and Linux. However, I only tried it on Ubuntu Linux. Unfortunately, there are no native .deb packages for Ubuntu Fiesty (but there will be for Gutsy, the upcoming version scheduled for October). The game is offered as a binary .tar.gz package with an .sh executable. No installation was necessary: it was a simple extraction.

Running the game

This is probably the game's worst point. Simply double-clicking the FretsOnFire executable did not work, even when I chose to run it in the Terminal. To run it, I actually had to open a terminal window, cd to the game's directory and run ./FretsOnFire . You are then greeted with a full-screen of slow graphics and choppy music. To fix this, I had to quit the game and turn off Beryl. Once Metacity was running, I started the game again, and it seemed to work well.

Playing the game

The game is played with the keyboard. There are 5 fret keys (though most of the songs only use the first four) and the Enter key, which acts as a pick. If you've ever played DDR, this game is similar: press the right fret key at the right time. I've never actually played Guitar Hero, so I can't really compare them.

A setback for the game is that only 3 songs, plus the tutorial, are included. However, you can download more songs on sites like Keyboards on Fire.

The game, despite its perks, is really fun and addictive.

Technical aspects

The graphics are amazing too. The game is programmed using the free Pygame library, making it completely OS-agnostic: it can run on any OS with Python and Pygame on it. The sound is not the best, but maybe it's just the songs that are badly recorded or something.

Conclusion

Pros: free and cross-platform, lots of songs available, good graphics, fun and addictive

Cons: no native Ubuntu packages, running it a pain, can't play when Beryl is on, few songs out of the box, sound could be better

The bottom line: This is a fun game that you should really try out, despite its flaws.

Football: Brazil beats Argentina... 3-0??? WTF?!

2007-07-16T01:47:00.000-05:00

Brazil beat Argentina with an unexpected 3-0 result yesterday, taking the Copa América home once again. I honestly hate football (soccer for you gringos) most of the time, especially this tournament since Colombia lost 5-0 against Paraguay in their first match. Well, at least we beat the US.

9 things Safari has that Firefox doesn't? Yeah, right.

2007-07-16T00:36:00.000-05:00

I've recently read an article called 9 things Firefox should steal from Safari. However, most of the items on that article are things Firefox already has, at least on the latest Gran Paradiso Alphas. Here are my views on the 9 points.

Highlight the current text field: The author's right, there is a problem with the way XUL renders text forms, and it should be fixed to be native. Thankfully, Firefox 3 will correct this issue, at least on OSX, but not on Linux yet. Meanwhile, you could take a look here

Font rendering: If you use OSX, then Apple anti-aliasing should be used. If you use Windows, ClearType should be used. If you use Linux, then the native anti-aliasing should be used instead. Again, it's a clear matter of Firefox-is-not-native-enough.

The downloads dialog: Well, I think Firefox's is much more useful.

Rendering speeds: Have you tried Gran Paradiso lately?

The bug reporter: He's right, Firefox's bug reporter should and will be improved.

The Find dialog: There should be an extension for this; it looks very, very useful. Take a look here to see if this helps a little.

Detachable tabs: No thanks. One window cluttering my desktop is more than enough. Why was tabbed browsing created for anyway? And, if it's really absolutely necessary, that monstruosity called Tab Mix Plus has it anyway.

Draggable Images: Firefox 3 on Linux has this, pretty graphics and all. Not on Windows, though. Must be the version of Cairo.

Resizable Text Areas: You're absolutely right about this too. That what bookmarklets, userscripts and extensions are for.

So, to sum it up: Firefox needs to be more native, and you need to wait for Firefox 3. Nuff said.

Top 10 Reasons to Switch to Ubuntu Linux

2007-07-14T09:48:00.000-05:00

I can't believe it's been almost a year already since I switched to Linux, Ubuntu specifically. I have to say, it's been one of the best times in my digital life. GNU/Linux is one of the best operating systems there is, and here's why.

1. Bullet-proof security

Linux is no doubt renowned for it's amazing security. But they never really tell how simple life becomes for the end user because of this: No need to constantly buy updates for Anti-virus software. No need to constantly scan for spyware and other malicious software. No worries that some vulnerability that hasn't been fixed for over 12 years might be used to turn my PC into a zombie. This takes us to the second point...

2. Easy-peasy updates

Modern Linux distributions, like Ubuntu, include a very complete packet management system like Apt which automatically updates ALL your software, not just the basic operating system. All your applications are kept easily up to date, from the Linux kernel to OpenOffice to the latest open-source game you installed the other day. And this adds even more force to point number 1, since updated applications = more security.

3. Awesome 3D graphics

Everyone who's even remotely into the open-source world has someway or another heard of Beryl and Compiz, the two compositing window managers that turn your desktop into a cube, amongst other things. But it's not just about the eye-candy: it's actually really, really useful. Managing multiple desktops is a breeze with the cube. This keeps individual desktops uncluttered and allows you to have, for example, a full-screen game on one desktop and OpenOffice Writer on another one.

4. No-brainer software installation

Let's walk through installing an app in Windows: 1. Search online for hours for the right program, 2. Download software, 3. Open installer, 4. Read 10-page long license, 5. Click next, 6. Repeat step 5 some ten times, 7. Click finish, 8. Restart computer. In modern Linux distros like Ubuntu, it goes like this: 1. Open packet manager, 2. Search for required program, 3. Check it, 4. Click OK. That's it. No need to go through dozens of steps in a wizard: it's all done by the packet manager. No need to browse online for hours: most of the software you'll ever need is available through the manager. No need to install. And best of all: most of these applications are completely free!

As a side note, if you use a Debian-based system like Ubuntu, installing apps is even easier by using the command line: just type "sudo apt-get install [appname]".

5. Helpful community

You might not get free corporate support, but Ubuntu's community support is amazing. The Ubuntu forums are full of people willing to help fellow users, and will most probably help you fix any problem you might have.

6. Shipit

A really nice thing Canonical has done is offer free CDs of Ubuntu shipped wherever you may be. You don't have to even pay for shipping! This is specially useful if you're still on dial-up and can't download the 700 MB CD image. So, head over to shipit.ubuntu.com and order yours today.

7. Perfect out of the box

Now I'm starting to sound like one of those Get-a-Mac commercials. Windows comes with NO office suite included. Windows comes with NO good image editor included. What does Windows come with anyway? Oh, yes, garbageware like 50 different ISP subscriptions. Linux comes with only the software you need, and with all batteries packed. It usually includes the powerful OpenOffice suite, the near-pro level image editor The Gimp, the amazing web browser Firefox, and many other programs, for free!

8. Extremely customizable

One of the best things about Linux is its free spirit. You are completely free to modify your operating system as you want. This allows you to customize everything to fit your needs. Don't like having just one panel? Take two, or even three! Don't like the way your multimedia keys work? Arrange it how you want! Don't like XMMS? Try Amarok, or BMP, or Listen! Don't like Vim? Use Nano, or Emacs, or Gedit! There are literally millions of choices to tweak your system the precise way you want it to be.

9. Zero Cost

One of Linux's key selling features is its price, or rather its lack of it. Most Linux distros, including Ubuntu, are donated to the community and have no cost whatsoever, unlike Windows, whose crippled entry version, Home Basic, costs US$200, and its bloated one, Ultimate, costs US$400.

10. Completely Free, but as in Freedom

Apart from being completely free as in free beer, GNU/Linux is completely free, as in free speech. You can download it, copy it, give it to friends, copy it some more, and even modify it. Not only is this completely legal, but you are actually encouraged to do this. So go ahead! Spread the freedom! Use Linux! Use Open Source Software!

How to: Make Firefox 3 Alpha 6 (or any pre-release version for that matter) portable

2007-07-11T19:47:00.000-05:00

Now that Firefox 3 is approaching its beta milestone, more and more people are enthusiastic about trying out its new features. In a previous post, I mentioned some of the novelties Gran Paradiso Alpha 6 offers. Now, I will teach you how to make this new and improved version of Firefox portable so you can run it from a USB flash drive or an iPod on any Windows or Linux-with-Wine computer.

Step 1: Get Firefox Portable

Go to the PortableApps website and download the current (2.0.0.4) version of Firefox Portable.

Run the installer and extract Firefox Portable to any directory you want, like your flashdrive. For the purposes of this tutorial, this directory will be G:\FirefoxPortable

Step 2: Download and install Firefox pre-release version

This can be Gran Paradiso Alpha 6, or the latest Minefield Nightly Build, or any other version of Firefox that you want.

If you downloaded a Win32 .exe installer, just install it on any folder in your computer, say C:\Program Files\Gran Paradiso.

If you downloaded the Nightly Build in the .zip archive, it's even easier. Just unzip it to the most convenient location you have at hand, like your desktop.

Step 3: Delete Firefox 2 files from Firefox Portable

Go to the place where you installed Firefox Portable (say, G:\FirefoxPortable) and delete every file in the \App\firefox directory. That will leave you with just the Firefox Portable launcher, but no Firefox program.

Step 4: Copy pre-relase files to Firefox Portable

Go to the folder where you installed Gran Paradiso or Minefield and copy all the files there to the G:\FirefoxPortable\App\firefox directory (or wherever you installed Firefox Portable).

Step 5: Enjoy!

That's it. Just run the FirefoxPortable.exe launcher now, and after a couple of seconds Gran Paradiso or Minefield should start.

So, to sum it all up...

Download & install Firefox Portable

Download & install Minefield or Gran Paradiso

Replace Firefox 2 files with pre-release files on Firefox Portable

Hope this was helpful, and remember: only use Alpha and pre-Alpha software at your own risk!

6 Essential Tips for a Faster Windows

2007-07-07T10:28:00.000-05:00

Since I'm the official computer geek everywhere I go, people tend to ask me to fix their computers because they're running too slow. This is normally what I do (or tell them to do) to their computers to help them.

1. Uninstall programs you never use

Head over to the Control Panel's Add/Remove Programs and uninstall those which you don't use. Why would you need Google Toolbar for Internet Explorer when you always use Firefox? Why would you want to have Azureus and uTorrent (especially when uTorrent is much lighter)?

2. Do not use Norton or McAffee antivirus software

These are BIG memory and CPU hogs, and they're expensive to boot. I often recommend a better, free antivirus called Avast, which is faster and more light on system resources.

3. Use a faster webbrowser

Most webbrowsers are heavy on system resources. Particularly, Firefox has a lot of memory leak problems. One thing you could do is remove extension and themes that you don't use from Firefox. Or you could use an entirely different browser. On a previous post, I mentioned K-meleon, an extremely fast, extremely customizable alternative to Firefox. If you find that your computer gets too slow when surfing the web, try it and see the difference. And please, please, please do not use Internet Explorer.

4. Use QuickTime Alternative and Real Alternative

Both QuickTime and Real Player suck up your memory by running in the background. If you use any of these programs, I highly recommend you uninstall them and get QuickTime Alternative and Real Alternative, which don't run unless you want to play a file. Best of all, streaming media works exactly the same.

5. Do not use an indexer like Windows Desktop Search

While they are extremely useful, desktop search engines like Windows Desktop Search and Google Desktop take up a lot of CPU and memory when indexing. If you want your computer to be faster, you should uninstall or disable them.

6. Generally, use lighter alternatives to software you already use

If, after doing all of the above, you still feel that your computer is way too slow, try searching for alternative, faster software that can do what the bloated programs you use can. For example:

Choose foobar2000 over Winamp, iTunes and WMP
Choose uTorrent over Azureus
Choose Abiword and Gnumeric instead of Word/Writer and Excel/Calc, and so on.

Overall, following these tips will make you computer run much faster. But if it's still not fast enough...

7. Get rid of Windows, once and for all

This is usually the first piece of advice I give to someone with a slow computer. ;) If you really want a fast computer experience, Windows is not for you. I highly recommend Xubuntu, a lightning-fast configuration of the famous Ubuntu GNU/Linux distribution.

That's really all the advice I can give you. If you have anything to add to make a Windows computer faster, don't hesitate to leave a comment.

Review: First look at Firefox 3 Alpha 6

2007-07-06T11:21:00.000-05:00

For those who haven't heard, the new alpha for Firefox 3, Gran Paradiso Alpha 6, was released a few days ago. I've been using Alpha 5 on Linux for a while now, and I can say that it's pretty fast, much faster than Firefox 2. Since Alpha 6 was recently released, I decided to download it and test it out.

If you look at the screenshot, you can see that it's not much different from Firefox 2. That's because most of the changes on Gran Paradiso are not visible by the user.

All but one (Adblock Plus) of my previous extensions were disabled because they were not compatible with this new version. However, as GP enters beta testing and the final version draws near, most developers will upgrade their extensions to work with it. If you just can't wait, there's an extension called Nightly Tester Tools that can force incompatible extensions to work.

There is, however, a new feature in the Addons Manager that will most probably make life easier for extension and theme fans: a permanent "Restart" button. Previously, this button only appeared when you installed new extensions and themes. This way, you can easily disable and re-enable extensions and change themes.

But that's really the only visible change in Firefox 3a6. The rest of the changes are 'under the hood'.

One of them is a new version of SQLite. You've probably heard that Firefox 3 will feature a faster Bookmarks/History/Feeds engine built on this database (know as 'Places'), so a newer version means better performance and new features.

Another simply AWESOME feature it has is that when you change the text size on a webpage (for example, by holding Ctrl and moving the mousewheel), the setting are preserved. The next time you open that webpage, the text size will be the same as you configured it the last time. I've been waiting for this feature for a VERY long time.

There have also been changes to rendering engine to make text look better. If you read lots of Thai pages, for example, the script should be better supported in this version. Also, the Download Manager has been improved somewhat. For the whole list of changes, check out the release notes.

Overall, this version of Firefox, although it is an Alpha still, is extremely stable and very fast. It is certainly NOT Alpha quality; it's more like Release Candidate quality. However, the recommendation is to not use it for other than testing purposes, since it is still in an early step of development and might be prone to lots of serious bugs.

A whole country crying out for peace

2007-07-05T13:51:00.000-05:00

Today, the streets of all the main cities in Colombia were crowded with people asking for the freedom of all the hostages held by the rebel forces and for the bodies of the 11 assassinated deputies killed on June 18. The marches have been enormous; thousands of civilians, the President, the ministers, the mayors of Cali, Bogotá, Medellín and other cities, and even the singer Juanes have all been out on the streets crying out for peace in this country, for unconditional liberty for all the hostages held by the FARC. Let's hope that, for once, these terrorists listen and understand that all they are really doing is damaging this country.

Today, the whole country is crying out together: "We want freedom. We want peace."
