Opera 10.50 released

Posted by dale | Browsers, Software | Friday 5 March 2010 4:42 pm

I keep writing about the Opera browser, I can’t help myself.  Opera Software has put the Opera web browser at the forefront of web browser technology with innovative features, some of which are unique to the Opera browser.  Admittedly the browser technology crowd is an incestuous bunch, and steal ideas back and forth from one another, still Opera has been doing it better, and more uniquely than any other browser for a couple of years now.  What I don’t understand is why it only has 3% of the market share, it deserves a larger share of the market.  Here’s why.

With this new release 10.50, Opera has introduced a new JavaScript engine, actually three new engines combined, that together, increase the speed of the browser up to seven times faster than the previous version, which was already fast.  Opera Software claims Opera 10.50 is the “Fastest Browser on Earth.”  It is.  Couple that with a perfect score of 100 on the ACID3 test, and you have a state-of-the art, W3C web compliant, lightning fast, web browser, and there’s so much more.

Opera has joined Cloud Computing in using additional servers on the Internet to enhance your browsing experience in three ways that currently no other browser supports. First, we have Opera Turbo.  Opera Turbo can be used by people with slower Internet connections.  Opera turbo compresses the web page on the server to up to 80% of its original size to speed your download speed.  This will improve your browsing speed on some of the slower wifi connections in retail coffee houses also.

Second, we have Opera Unite. Opera Unite allows you to share music, videos and documents with friends without having to either email the content to them, or uploading the content to a server.  It sets up a virtual server between your friends over the Internet. This means larger content files like movies can be shared with your friends easily.

And finally, we have Opera Link.   For those familiar with Delicious, a web service that allows you to centralize all your bookmarks and put them on the Internet, Opera goes one step further.  You set up your Link account in each of your computer browsers.  From then on Opera Link can keep your Bookmarks, Browser configuration, history, Speed Dial, Notes, and Searches synchronized with all the rest of your Opera browsers automatically.  If you set a new bookmark in your browser at work, it will automatically show up on your home browser.

That brings up Speed Dial, which shows you images of your favorite web pages you can click on when you open a new browser window.  Unique to Opera is Visual Tabs, pull down the menu tab bar and an image of the web pages in your tabs are shown.  For those small fonts on the web page, and for readers who can’t see the page, there is a Page Zoom icon to quickly zoom in to the web page with a simple click of the Page Zoom icon on the bottom right toolbar, that’s nice.   With Notes, you can select some text on a web page, right click, and save it to Notes.  This automatically saves the text and the web URL, for reference later.  And it’s not limited to one note, like Microsoft’s copy and paste.

Then we have faster browsing with a series of enhancements.  Mouse Gestures allow you to customize your mouse movement. To give you an example, right click on your mouse, and move your mouse to the left, and you’ll go back to your previous web page, no more having to place your mouse on the “Back” icon at the top of the browser to go back one page. There’s Fast Forward to go to the next page, like the back button, this one guesses what your next page would be, and takes you to it.  No more going to the bottom of the Google page to find the next page number.  And there’s a fast back to take you to the original page of your search.  Opera will fill out the user name and password for a particular web page automatically if you like with their Password Manager.

You need a Dictionary, an Encyclopedia, or to Translate a word into another language, select the word, and right click, and select what you want to do.

If you close some of the tabs you had open and closed the wrong one by mistake, no problem, there’ a Trash can icon that keeps track of tabs you closed. You can also browse History Free if you prefer.

Have you ever wanted to find a particular word on a web page full of text. One way you could do this is with Alt-F then type in the word, Opera makes this a little easier with Find in page,  just type a period with your word, and it is highlighted on the screen.

Windows7 and Vista introduced Widgets for little applications you wanted on your desktop. There’s Opera Widgets that do the same thing in your browser window.

And now to features that I really like.   Google’s Chrome originally allowed you to type your search into the address bar.  They were the first, then Firefox followed, Opera has done them one better with a Quick Search.  You can type your search into the address bar, like with the other browsers, and in Opera you can assign a one letter url for the address bar.  Let me give you a couple of examples.  I want to search for a JavaScript book on Amazon, type “z javascript” in the address bar and you’ll go to Amazon books and the JavaScript books page pops up.  You can type “w php” and bring up the Wiki for php, or “e ipods” and bring up Ebay on the ipod page.   What’s nice is you can create your own custom key shortcuts also.   If you go to Amazon a lot this really simplifies getting to where you want to be.

And finally, Opera is starting to listen. I have said many times before that if Opera would put out some decent web development tools, I would give up Firefox for web development and use Opera full time.  With this release the Alpha of Opera Dragonfly is being released.  This will be a full-featured development environment allowing you to debug JavaScript, inspect the DOM, the CSS, network traffic and data stores with built-in remote debugging for mobile devices.  To view page source, go to page->Developer’s Tools->source, or validate, or Inspect Element. You can Inspect the element on the page with a right click of the mouse.   This is an Alpha version, some of the choices are not functional yet,  as to be expected with an Alpha release, like the color picker, but Operation Dragonfly, the equivalent to Firebug on Firefox, looks like it has the potential to out do Firebug in functionality once everything gets hooked up.

Opera, now that you are finally moving to be a full fledged web development tools, let me help you.   Things I missed in Opera Dragonfly for Web Development, that I want.  The F12 key to bring up the application, and put it back down, quickly.  The Inspect button in Firebug that allows you to search the screen for an element with your mouse.   Yes, Dragonfly does it with the right click, Inspect Element, but its not the same, or it’s not fully functional yet.  I’d like an Aardvark plug-in type of functionality where I don’t have to bring up Dragonfly to view the DOM element.  I want to see all the CSS affecting the page with file names, like Web Developer, View CSS, in fact the entire Firefox Web Developer plug-in would be nice.

Keep working!  Your doing great work. Your web development tools aren’t quite there yet, but I see you’re actively working on them, as you get closer and closer, you may win me over for Web Development, you already have for general web browsing.  For those who have not tried Opera, I recommend you try it out, you might like it.

Opera and Firefox release new Browser Versions – a Review

Posted by dale | Browsers, Software | Friday 12 February 2010 6:02 pm

Opera has just released version 10.10, today, and Firefox recently released version 3.6. Currently of the popular browsers, Chrome is the fastest, followed very, very closely by Opera, and Safari, with Firefox coming before Internet Explorer, but way back from the rest.

Chrome is fast, but the interface is different with its top line tabs and Omnibox combined search and browser address window. It takes getting use to, and I have not been using it, because it was not stable initially.

Internet Explorer is way behind in browser compatibility and speed, and is an after thought in my mind. When and if Microsoft ever gets up to W3C standards, decides to use web standards for determining box widths instead of their proprietary method, and passes the ACID3 test, I might consider it, but not before.

Safari is fast, and it looks nice, but they do this by pumping up the luminance or gamma of their colors from all the other web browser colors, so the browser colors look sharper. Unfortunately, I can’t use their colors system for development when I’m building for all browsers. I’ll leave the Safari browser to Mac Users.

Which brings us to Firefox and Opera. I use Firefox about 70% of the time, mostly because of its web development plugin tools. There are three plugins I recommend for web development: Aardvark, Firebug, and Web Developer. I use all three. This makes Firefox unique as no other browser has these tools. Consequently, it is my web development browser of choice. Yes it loads slow as molasses, but everything runs fine once its up. I had to wait until the Aardvark plugin was ready, but now I’m up and running on 3.6.

What’s with 3.6? Firefox claims speed improvements in page loads, and it looks like this is true, it’s much faster loading both pages and booting, but still doesn’t seem up to the other fast browsers. Last release Firefox reached a 93 on the Acid 3 test, but rather jerkily. It now reaches 94 smoothly, still not 100. You now have type ahead in the address bar, which they call the “Awesome Bar.” Just start typing the site name and possible sites are gradually filtered to give you the correct URL. This is a rip off of the Chrome Omnibox, but there search capability is limited compared to Chrome. You now have one click bookmarks by clicking the star in the “Awesome Bar” window, and there are bookmark tags, like Delicious. Type a tag in the “Awesome Bar” and all your tagged items URL populate. This does not yet synchronize with your other Firefox browsers. They now have a Private Browsing option you can toggle. I’m skeptical of this, as Google keeps a complete record of all your browsing and your searches in its database. For looks, they have 35,000 personas which changes the look of the browser, to me this is just fluff.

And now to my favorite browser, Opera with its new 10.10 release. Opera is fast, and looks great. Only about 2% of the population uses it, so there is very little problem with malware, or virus attacks. It’s safe, secure, meets W3C standards, and passes ACID 3 quickly with flying colors. It’s a great browser. If it had the Internet tools of Firefox, I’d never look back and use Opera full time.

With Version 10.10 Opera claims five things that you can only do in Opera: Application sharing of data with others, compress web pages to load pages faster for people with slow data connections, visual tabs where you see a thumbnail of the web page, in addition to the text tag of the tab like in other browsers; customize your web page thumbnails in the speed dial window, synchronize your tabs, bookmarks, and other data with your other Opera browsers over the Internet. This is like Delicious in its synchronizing. Opera also has integrated themes for looks, and an integrated Opera mail program, although I admit, I prefer Thunderbird at the moment.

If you’re a die-hard Firefox user, you’ll like the improved Firefox speed and tags with the Awesome bar. If your not into web development, I highly recommend you download Opera and give it a test drive, check out the speed, convenient surfing tools, and overall good looks. Change the appearance in tools->appearance, drag the tag bar down to see the visual tabs, and enjoy Opera.

Printer Drivers for Ubuntu

Posted by dale | Hardware, Installing Software, Software, Ubuntu | Monday 18 January 2010 8:04 pm

Ubuntu comes with drivers for most of your peripherals, except printer drivers, which normally are installed separately.  In a previous blog I have written favorably about the Canon MX850 compared to the equivalent HP ink-jet all-in-one printers.  Having a good feeling about Canon, I went to their web site and made an email inquiry about a printer driver for Ubuntu.  Here is their reply, “While considering the desire to provide the best possible support for Canon’s products, Canon must make decisions on which products to support when new operating systems are introduced.  Currently, Canon has decided to support only the Microsoft Windows and the Macintosh operating systems.”

Pardon me, Canon, but Ubuntu and Linux are not new operating systems.  They’ve been around almost as long as Windows, and the Apple operating system is based on Linux.

Have no fear, though, this happens occasionally and what you’ll find when you go looking for a solution is other solutions.  Searching further, for Canon printer drivers, there is a free solution, the CUPS-BNJP Printer Driver, which mimics the Canon BNJP printer protocol for the Canon Pixma printers and works over the network. This also works with the XSane scanning software provided with Ubuntu to allow scanning of documents.

CUPS-BNJP is based on CUPS, CUPS works with other printers besides Canon.  It was built for the Fedora distribution of Linux.  Since Ubuntu uses the Debian distribution, there may or may not be an issue in using CUPS with Ubuntu.  We can check that easily.  If you go to Applications->Ubuntu Software Center->Get Free Software->System Tools and scan through the list of available software, you’ll come to two choices: Printing, Printers.   If you click on “Printing,”  a CUPS printer driver is available.  “Printers” on the menu system gives you a GUI interface between CUPS and the printer.

CUPS uses your web browser to view print jobs, manage your printers, and for online help.  However, it makes use of the command line for its configuration.  The printer GUI in the Ubuntu Software Center. according to the software description,  seemed like it depended on some other software for configuring remote printers on a LAN,  if you don’t want to install a series of dependent software, or if you prefer not to use the command line interface, you probably want to check out a commercial solution, TurboPrint 2 for Linux.

TurboPrint 2 supports ink-jet printer’s from: HP, Bother, Epson, and Canon for all Linux distributions.  For the modest cost of $29 you can be ensured that you printer will function, and pick up a nice set of additional features with the software.

TurboPrint2 features include: high print resolutions, color management that matches screen document color to printed color, printer status monitoring to track print progress and errors, like a low ink cartridge, printing on both sides of the paper, print preview of what your about to print, and intelligent ink management to save ink and extend cartridge life. The one remaining question that I had is will it work on a printer attached to your network, and it will.  This intelligent printer utility has Windows and individual manufacturers printer drivers beat hands down.

The company provides a trial version to see if it will work on your system. You can download from the web and hook it up and if everything works, then purchase the software.  What’s not to like!

Given I was not sure about the Cups-BNJP distribution with Ubunutu,  the GUI configuration tool appeared to need additional software to pick up my printer on my LAN,  which meant there may be some additional configuration issues beyond just downloading the software, and  a free trial of TurboPrint was available, I decided to go with the TurboPrint option and give it a try.

TurboPrint Control Center and Printer Monitor

I downloaded the correct distribution for Ubuntu from their website. Clicked on the install button, the install wizard came up and installed the software.  The installation was painless.  The only thing that made me pause was the request to add a printer before other functionality was available.  This is done with the “Add” button in the Print Control Center.  My model Canon was recognized immediately on my LAN and that was it.  I printed a test page, checked the level of my ink cartridges, and was suitably impressed.

Considering I didn’t have to read any documentation, install several pieces of software,  or potentially do a command line configuration of the printer.  I was up and running in 5 minutes,  and had some one to turn to for support if any problems cropped up, it certainly is worth the $29 asking price for Turbo Print to me,  so much for printer drivers.

Chrome – a Review of the New Version

Posted by dale | Browsers, Software | Tuesday 22 December 2009 3:02 pm

Google just released a new version of their Chrome browser available for download.  This is version 3.0.195.38.  If you have Chrome installed you’ll get a new version annoucement pop up,  and its an easy install to upgrade from your previos version of Chrome, or you can download the new version by going to the Chrome download page.

I ran the Acid 2 and Acid 3 Tests on the new version, and Chrome passed with flying colors.  Safari, Opera, and Chrome are the only browsers to reach 100 on the Acid 3 test to date.  Firefox is close with a rather jerky 93 after an awkward pause at 69.  Internet Explorer 8.0 failed the Acid 3 test with a miserable score of 20 after a long stop at 12.  I guess we have to give Microsoft kudos for passing Acid 2 with Internet Explorer 8.0.  Maybe in another couple of years they’ll join the rest of the web, and stop trying to make every one conform to them.

Chrome is quick, a jaguar in loading internet pages.  It is the fastest browser out there followed by Opera, in both loading the browser window and returning web pages.

The Chrome Browser

Chrome has a different look than any other browser choosing to minimize menus and toolbars to increase the browser window space.  The tabs for individual browser windows are placed at the top of the page.  You can drag a tab off the tab bar and create another instance of Chrome with that window in it, and you can make the instance disappear by dragging it back to a tab in another open Chrome instance.  Tabs can be reordered by dragging them where you want them on the tab bar. Pretty slick.

The web url address box doubles as the search box. If you don’t know the http:// url for the web site you want, you can just type the name in the box and a drop down of possible url’s appears.  If you want to search on the name, hit the arrow key on the right and a full Google search page appears.

There is a stealth window called “incognito” that allows you to search without saving any history.  Hmmm, I wonder why you’d want to use that?  It reminds me of the old “boss” key.

There are some 95 themes that you can pick from to change the appearance of the initially loaded  browser window, although I must admit, they don’t do much for me, except change the color at the top of the page.  The themes are predominately female and kid themes, no good old American macho man themes, darn.  The browser’s initial window, in addition to loading the theme, loads the former pages you have just loaded in thumbnails for quick selection of previous browser windows, an idea originally started by Opera.  You can rearrange these thumbnails by dragging them to a new position.  No biggee.

You can also create desktop icons for web applications.  This gives us a good indication of what direction Chrome, and Google, plan on moving toward in the future.  Bye, bye, windows desktop.  The king is dead, long live the new king.  Hello, the Chrome internet desktop.
