Installing (first) OmniRom nightly for Samsung Galaxy S2 (I9100)

After a successful installation last night, here is the recap of what happened so that some of you may find it useful (eventually).
Before flashing OmniRom, I was on latest CyanogenMod 10.2 nightly. This means there was already ClockWorkMod Recovery (CWM), root access, and what not. These are the prerequisites I won't go into.

Background

A little background information might come in handy here. OmniRom is the next Cyanogen, in a way. After CyanogenMod became a commercial entity several of its (now former) developers wanted to keep the spirit of free software, community, etc. going and they formed OmniRom. This was also (one of) the first ROM to bring Android 4.4 KitKat to not-yet officially-supported devices, including Samsung Galaxy S2. The above facts should be enough to make you want to try the ROM out, right? It was for me. That and some spare time were enough to jump ahead.

Backup

First, as always, it is a good idea to make a backup. However, in this case it turned out to be a waste of time. First because SD card wasn't deleted in the process so all my files, settings, backups, etc. were still there when the new Rom booted. Some early adopters reported that there was no external SD card accessible from the Rom but this was not an issue in my case. So, all my files were still there but backup gave a bit higher sense of security.
The important thing I *didn't* do was to actually backup each application from its own settings and options. I'm not sure if Titanium Backup could restore the apps from earlier Android versions so it would be a good idea to back up each application that has your data through its interface.

Download

Next comes the download.
OmniRom for Galaxy S2 (i9100, *not G*) is available here. There is only one build currently.
GApps must be specific build and what not. The ones I used are here. No issues whatsoever.
SuperSU I used is v1.80. Available from here.

I downloaded on a PC and then copied to the root of the phone's SD card via USB cable. Fortunately, CWM could read both internal and external flash cards, including subdirectories, so the location would not matter so much.

Installation

Installation was pretty smooth. The instructions I followed up to certain level came from here. In brief, what happened is:
  1. Rebooted into (CWM) recovery.
  2. Wipe Data/Factory Reset
  3. Wipe Cache partition
  4. Wipe Dalvik Cache from Advanced options
  5. Install Zip - ROM (omni-4.4.1-20131206-i9100-NIGHTLY.zip)
  6. Install Zip - GApps (pa_gapps-modular-mini-4.4-20131126-signed.zip)
  7. Install Zip - SuperSU (UPDATE-SuperSU-v1.80.zip)
  8. Reboot
The first boot was either too long or the device was stuck so I turned it off and boot into Recovery again by pressing Volume Up + Home + Power. This time it was already TWRP Recovery that comes with OmniRom. Then I did again
  1. Wipe Cache Partition
  2. Wipe Dalvik Cache
  3. Reboot
 This time the system booted itself up happily and quickly. Then came the customization of the new system. Google account log-in was a bit tricky as my GAuthenticator for 2-step authentication was on the wiped Rom. Here I used one of the backup codes to log in, then moved the authenticator to the "new" device through this page. This was painless, fortunately. Pay attention to details before you delete your important data.
Moving other apps, like Dropbox, to the new code generator was equally easy. Simply register the new device in the web-app settings on the PC, for example.

That's pretty much it. I installed most of the applications I had previously simply by searching for them in the Play Store, Amazon Store, or F-Droid. Some applications had their own backup and that was restored, which is really helpful. Others I had to reconfigure manually.

Update: In SuperSU go to Settings -> Custom ROM -> Install SuperSU backup script, to avoid reflashing SuperSU on every update.

Impressions

The ROM seems basic so far. Pretty much the stock Rom that is available for devices like Nexus 7. Currently I'm missing some customizations, like customizable tile settings, ability to turn off led button lights, customize button actions, quick access to recent apps, turning off the screen, and so on. Unfortunately, all these were supported directly in (CyanogenMod) Rom so far and there are no applications that would do that. Hence I'm hoping the support for this will come later as part of OmniRom.

Most of other features are provided by applications so that's all fine. Oh, one thing - install Greenify to take care of the unwanted background process activity and save battery (and the planet).

Battery life after a day's usage seems pretty good. And I mean good as in comparable to the previous (latest CyanogenMod, which is considered stable as of last week) Rom. I did use Greenify to hibernate pretty much anything I don't appreciate running in the background so the playing field for comparison was even.

Things to watch

Delta updates: Apparently there are delta updates available. This is a welcome change and helps reduce the time and bandwidth needed for Rom updates. As there is currently only one build available for download, I couldn't really test that part. The thing to pay attention to is that delta updates are (supposedly) only supported through TWRP, not CWM. Something to try out once deltas are available for i9100.
Update: Deltas are available for i9100 as of Dec.12. In Settings -> About Phone -> System Updates check for new versions. OpenDelta will download the difference and create the new ROM file in OpenDelta directory on SD card. This is to be used to flash the new version. I guess it should be done automatically but this first one I had to do manually.

Customizations: As mentioned earlier, I hope some level of customization of button actions, notification light, etc. will become available for i9100.
Update: As of 20131212 there are new Quick Settings tiles available, like Airplane Mode.

Addendum: Customizations

Some applications can be used to replace missing functionality and those will be added here as I find them.
  • Elixir2 - toolbar in notifications, system profiles, sound profiles, lock screen ... So far suits most my needs.
  • Increasing Ring -  enables increasing volume for ringer and alarms.
  • [Volume Buttler - sound profiles and various ways of activating them.]
Some tweakers for i9100 are available but don't work with current kernel. In case they add support in the future, the links are below

Update: Further links are to be found on my OmniROM page.

Issues With DateTime Globalization

Background:
  • What's wrong with DateTime anyway? (link)
Libraries:
  • for .Net: NodaTime

DateTimeOffset does not help you with Daylight Savings Time!

This one is often a source of confusion. DateTimeOffset data type has been introduced to SQL Server but it is only a try (at best) to help out with TimeZone issues. It only contains the (numerical) offset from UTC but, as many know, that offset changes throughout the year. This is known by Daylight Savings Time (DST) and is in effect at different times at different regions in different years. The whole concept is getting obsolete as of late but it is still there and we have to live with it.

Check Jon Skeet's answer below and also have a look at NodaTime library that has a better implementation for working with TimeZones, offsets, and daylight savings.

Using LiveReload plugin with DocPad

LiveReload plugin for DocPad updates the web page, being previewed in a browser, when a change happens in its source code. This is pretty convenient when adding content as it removes boring and repetitive work, and provides immediate visual feedback, preventing possible missteps.

The missing link to having LiveReload working is to have the "styles" block enabled in the template.

Tips for working with Report Server (SSRS)

Below are some tips for working with SQL Server Reporting Services. The tips are absolutely necessary as almost every step, in case the report has any complexity, is slow and painful, and often unintuitive.
  • reporting services - How to get rid of blank pages in PDF exported from SSRS - Stack Overflow -set ConsumeContainerWhitespace to True
  • How do I best display CheckBoxes in SQL Server Reporting Services? (link) - use Webdings 2 font; or HTML source
  • Working with Dates stored as UTC - convert using SQL CLR UDF (link); access timezoneinfo from SQL (link);
  • Related links: TZI in SQL CLR (link), Issue with NodaTime in CLR (link), second (link), Enabling CLR in SQL Server (link), Create CLR Functions (link), Create and run CLR function (link); download SSDT (link); set database Trustworthy (link)
  • Another way of converting Dates is to convert them at the Report level. This leads to a different set of problems, like inability to use deployment from Visual Studio. Add code to a report (link), deploying assemblies (link) and one more (link), Using System.Core: Resolve issues with System.Core version (link). After adding a reference to System.Core the problems arise. Version 4 can not be used, hence a reference must be changed to 3.5.0.0. This breaks Deployment from Visual Studio. Manual upload will work and the report will run.
  • Setting visibility of a textbox
=IIF(First(Fields!Street2.Value, "AddressDataSet") is nothing or
First(Fields!Street2.Value, "AddressDataSet") = "", true, false)
  • Format date/time (link). Use =Format(value, "dd/MM/yyyy HH:mm").
  • Pass a parameter in URL (link). Simply add another key/value pair, such as "&key=value".
  • Rendering HTML (link
  • Set OverwriteDataSources property for objects at the Project level.

From Word to PDF using LibreOffice

Problem

Here I will put together links and tips on how to handle the following scenario. I need to produce a PDF documentation from a set of Word files in .doc and .docx formats. These have some content that changes and, to handle that, I would create a "template" file where the content would be adjusted on the fly. Then the documents would be converted to PDF format for distribution. Details on implementation are below.

Working with Template Files

Template files are just formatted text files. These can be .docx, .doc, or .odt formats. Custom tags are inserted into the file originally, and then replaced when the custom output is required. The purpose is to have a visual designer for documents and also a system that is easily customizable but, at the same time, easy to read and manipulate by a machine.

Word

Word XML (.docx)

There is a library for working with .docx format, for .Net platform:

Word (.doc)

These files can be read using MS Office or Libre Office.

Open Document Format (.odt)

  • Writer Demo using CLI link.
  • AODL library for manipulating .odf documents.

Direct Manipulation

While reading the template files can be done using native libraries, the templates are simple enough for a quick find/replace functionality of the plain text. Both .docx and .odt are, in fact, Zip compressed collection of XML files.
  • Zip packages are supported directly by the .Net Framework, using ZipPackage class.
  • Zip files are accessible through ZipFile class.

Converting to PDF

Word files are converted to PDF using LibreOffice.
  • Earlier mentioned AODL library can export files as PDF.
  • CLI-UNO Language Bindings also can be used to export .odt files to PDF in .Net directly.
  • Converting Microsoft Word Document to PDF format using OpenOffice.org (Portable), on CodeProject link
  • HOW TO: Convert office documents to PDF using Open Office in C# (link
  • Programmatically convert Word (docx) to PDF, on StackOverflow (link)
CLI-UNO library is available with default LibreOffice installation and is (usually) found at
C:\Program Files (x86)\LibreOffice 4\URE\bin\cli_uno.dll

Conclusion

There should be enough material here for the solution required at the beginning of the post.

Firefox - the best browser of 2013

Firefox is back to being the best browser, according to Tom's Hardware. While performance is a cool thing to talk about, reliability is much more important for serious work. This is the area where Firefox really shines in the latest releases, when compared to the competition.

Reliability

During the 40-tab reload, the team assessed the reliability of each browser to ensure all pages had fully rendered. The results were surprising:

  1. Firefox loaded all pages correctly
  2. Opera 12 required four tabs to be refreshed
  3. IE10 required eight (and the browser crashed first time)
  4. Opera 15 required nine refreshes
  5. Chrome required twelve — 30% of pages were incomplete or incorrectly loaded

 

The Firefox gets the top place by having overall good results, not just shining in minority of areas.

My new favorite launcher on Windows

As the search functionality on the new workstation sometimes gets stuck for ~10 seconds, effectively making it useless most of the time, I was back to searching for a custom launcher.
Fortunately, this category of programs is not forgotten. On the contrary - it is very well live and kickin'.
I used to be a fan of SlickRun but, over time, I simply utilized Windows start menu more by adding custom shortcuts. This was a hassle but similar to setting up SlickRun. So, no real benefits there.
Now I found a great new contender - Launchy. It has a great balance of ease of use, performance, and features offered.

The simplest way to add a link to webapp/website to Android home screen

The easiest way to add a shortcut to a web site (or web application) is to create a bookmark in your favorite browser and then add a shortcut to the bookmark at the home screen. How exactly to add the shortcut will depend on the home/launcher app you are using. Adding a bookmark is done through the browser.

Infinite Version is getting meaningless

"Infinite version" was a concept made popular by widespread transition to web applications that could easily be updated continuously. Google implemented the same with Chrome by using a brilliant system for automatic updating through distribution of differences between versions of the application.
One of the consequences was that the age-old rule for software versioning (link) has become pointless as the major versions were increased every couple of weeks without any significant change. Initially there may have been major changes in every new release but, as of late, the rate of those has slowed down. The versioning is now becoming meaningless with updates like the current Dev version of Chrome:

Chromium 31 Is Here, Chrome 31 Is Only Days Away: "Perhaps partially to offset the lack of new features, but mostly because it's tradition by now, the Chromium patch that bumped up the version number also comes with a few trivial facts about the number 31."

The lack of new features is confirmed at Google Chrome Releases blog (link): "This release fixes a number of crashes and other bugs."

The software version number is now just a sequence number to distinguish releases, stripped of any other information about the amount and type of changes included.

Checking disk drive under Linux

There is a time when old hard drives start to die out. Here are some tools to help diagnose the issues:

sudo badblocks -v /dev/sda > bad-blocks

Does a read-only check for bad blocks and outputs a file (bad-blocks in this case) with the list of the bad blocks found. The parameter can be a whole disk (as above) or any of the partitions. In case of a partition, use /dev/sda5, instead /dev/sda, for example.

sudo fsck -t ext4 -l bad-blocks /dev/sda

Fsck will read the contents of bad-blocks file and check the reported sectors. After analysis they will be marked as bad.

'Disks' is a GUI utility that displays the drives attached, including the partitions.

Android - Screen Off Utilities

Looking for a more convenient way to turn off the phone screen but not to lock it until the timeout expires (currently 10 minutes). This helps me avoid constant unlocking if I'm using the phone frequently.
Below are two convenient tools that assist to achieve the goal:

Screen Off Utils (link) - allows turning the screen off but doesn't force the lock;
Proximity Screen Off Lite (link) - turns the screen off on either the light sensor or proximity sensor signals. This allows turning the screen off when the phone is placed into a pocket or placed on the desk upside down (which I normally do).

PhantomJS: Headless WebKit with JavaScript API: "PhantomJS is a headless WebKit scriptable with a JavaScript API. It has fast and native support for various web standards: DOM handling, CSS selector, JSON, Canvas, and SVG."

CasperJS is "an open source navigation scripting & testing utility written in Javascript and based on PhantomJS — the scriptable headless WebKit engine. It eases the process of defining a full navigation scenario and provides useful high-level functions, methods & syntactic sugar for doing common tasks such as:

defining & ordering browsing navigation steps
filling & submitting forms
clicking & following links
capturing screenshots of a page (or part of it)
testing remote DOM
logging events
downloading resources, including binary ones
writing functional test suites, saving results as JUnit XML
scraping Web contents"

Zombie: Insanely fast, headless full-stack testing using Node.js

A testing framework that does not require a browser.

Insanely fast, headless full-stack testing using Node.js: "Zombie.js supports the following:

AngularJS: "Error: $digest already in progress"

Here is something that might save a few painstaking hours. While working on an AngularJS code in a web page, there was a need to pass some data from the server side for the initialization. Since the data was static and the page already had previous functionality, the easiest way was to dump the data in the form of JSON straight into the page when it was being rendered on the server side. Then, in Angular code this JSON data would be used when the code runs on the client side.
So, after a few changes the annoying "Error: $digest already in progress" error was popping up as soon as the dialog was loaded. Oh, right, another thing was that there was a dialog that was dynamically loaded from the server depending on what the user clicked. Then, each dialog had its own Angular controller.
To make the story short, the JSON initialization in a script tag was placed *inside* the div with ng-controller. This was triggering the exception as it messed up with Angular code, I guess.
Moving the script tag above the div with ng-controller helped and now the code works as expected.

Upgrading Fedora 18 -> 19 with FedUp

Today I tried to upgrade Fedora 18 to 19 using fedup. First I got an exception after it downloaded all the packages. It turns out there is already a fix for this. The trick is to install a newer version of fedup, which is not yet available in the Updates repository for F18.
The repository here - Index of /pub/fedora/linux/development/19/x86_64/os - contains the latest version of fedup. It is 0.7.3 at the time of writing, while F18 Updates repository contains only v0.7.1.
So, running with this newer version there is no crash but adding the installation repository parameter is now required. Using the above repository allows the upgrade to proceed.
The command line is below.

sudo fedup-cli --network 19 --instrepo http://alt.fedoraproject.org/pub/fedora/linux/development/19/x86_64/os/

Should you change your mind halfway through the process
sudo fedup-cli --clean
will clean up all the changes made so far.

Update: As described in the reply to the bug report, the installation repository above is the correct one if you are updating to a pre-release version of Fedora (which #19 currently is). Once it is officially released, any repository instance will contain the files to allow upgrading.

Another option is to download the (now available Beta) upgrade DVD and upgrade from there:

sudo fedup-cli --device /mnt/fedora --debuglog=fedupdebug.log

More info: http://fedoraproject.org/wiki/FedUp#ISO_File

Update 2013-06-12: The instructions page list another upgrade path, using ISO. The command is

sudo fedup-cli --iso /path/to/file.iso

While upgrade with specifying the path to the contents of the mounted ISO file didn't work for me, the upgrade using the ISO file actually worked and the system was upgraded.
After the upgrade, a manual intervention was required. I had to update a lot of packages that were still available on the system. A lot of help was provided by
sudo package-cleanup --orphans

BeWeather & Widgets - Android Apps on Google Play

This is now definitely my favourite weather app for Android. It does not run as service, unless you want it to. As a service, it can be set to auto update. Each location can have its own update interval. And the temperature can be shown in the notification bar.
But, since I don't like apps running as services, I prefer to update when I actually open the app. BeWeather can find your location and then show the weather data from the nearest Weather Underground station. Once the location service is disabled, the location will remain cached in BeWeather and the weather will be updated for that location.
Other locations can also be added by simple search. There are beautiful weather animations for those who like extra visual experience. I'm quite happy with static images, which are also pretty.
There is also the animated satellite image for selected location, daily forecast for next 7 days, hourly forecast for the current day, sunrise and sunset times, and maybe a few more things.
However, all the stuff above is more than what I would expect from a decent weather app and this is it. After about a month of usage, there is not a single thing that is wrong about this app and that makes it onto my favourites list.

Google App Engine deployment with proxy

Similar to Node Package Manager, Python, Java, etc., Google App Engine can read HTTPS_PROXY variable in order to use a proxy server to access the Internet.
Simply
set HTTPS_PROXY proxy.server.domain:port
before running the App Engine Launcher and everything will work fine. The reason is that the App Engine is written in Python (on in Java, if you're using that one) and it is Python that is using the proxy server and reads the environment variable.

Dot TK employs shady tactics

So, I have just realized how Dot TK is playing out their tactics for making extra bucks on the domain names. They offer free registration of .tk domains to everyone, stating that this promotes the island, helps tourism, yada yada yada. It is really no problem to register the domain, find a DNS host that will host the domain and, voila, everything works.
However, beware that when the domain expires it will simply redirect to spam advertising site to get your traffic. This is quite annoying and does not help understand the root of the problem. Looking under my account, the previously-registered domain was not listed there at all!
When I tried to re-register the domain, I was told that the domain is now a "special domain". Thus, it requires a payment that is higher than regular domain name registration. So, not only it is not free anymore but now it costs more than a paid domain!
Communicating with the support pays off. In my case it turned out that the domain expired and everything was set right promptly. In that regard, I salute the support team but the fact that it is not obvious what happened and that there is no way to extend the registration after it has expired, but redirects to some nasty sites, is quite a disappointment.
So, make sure you renew your domains on time.

Working with Variables in Selenium IDE

Selenium IDE allows storing and recalling values in the scripts.
To get a value from a hidden field use

To retrieve this variable later simply refer to it as
${itemId}
inside any other command.

Looking for Bookmark Manager

It's been so many years but bookmark management is still a pain in a wrong place. My bookmarks are now spread out across systems and programs and it is hard to pick up which one is where. Now I'm embarking on a task of finding a decent bookmark manager that:
  • works across platforms (Android, Linux, Windows, for a start)
  • syncs across those same platforms
  • allows quick search
  • allows locating the search results in the folder hierarchy
  • has notes field that is searchable
  • works with whatever the default browser is
Here are some findings:
  • NetVisualize Favorites
    So far I've used NetVisualize Favorites for years. It worked well on Windows and synchronized through Dropbox. Worked with any browser. However, it is not being developed further so it is missing all the modern features of cross-platform and online cooperation. That's why I'm looking for alternative.
  • Firefox Bookmarks
    While convenient as cross-platform tool that syncs, it is sometimes suffering from performance problems.
  • Chrome Bookmarks
    Has sync across platforms and devices. Missing description field and search. Annoying thing on desktop is that it is impossible to figure out the directories where the search result records are stored. Directory information adds a lot of useful contextual information to the bookmark and not having it available is confusing.
    On mobile there is a bug in layout that makes it impossible to work with even a moderate number of bookmarks.
  • Opera Bookmarks <- br="" current="" favorite="">What a gem. Someone recommended this and now I'm using it as a default bookmark manager to try it out.
    Has versions for Android, Linux, Windows. Syncs across platforms.
    NetVisualize can export directly to Opera format, together with Description field!
    Has awesomely fast quick find that search in Description.

Static-site generators

Looking for a templating engine that generates a fully static-HTML web site.
Some initial leads come from Node Based Static Site Generators post (link).
The requirements would be that the templating engine can run on lots of machines. A Node.js-based engine would be great. Although limited to PCs when ran directly, it would allow working with online IDEs to modify the site contents.

Blacksmith

Uses marked templates and is relatively simple to get going. I would still prefer something simpler as sometimes it is not obvious what is missing in the overall structure of the files.

DocPad

Current favorite.
The file structure seems the simplest. Supports MarkDown templates (marked). Has a file monitor that rebuilds on any file save, and a built-in server for previewing the site.
Quick start (link)

Wintersmith

Uses jade templates which are some hybrid between MarkDown and HTML. This is a half-way solution and I see no point using this quazi-HTML instead of the real thing. Or, if moving away from HTML (the presentation) to the content then I would prefer something like MarkDown.
The library is extensible but one would have to write an own plugin to be able to use marked templates.
No go.

My new favourite Windows network traffic monitor

NetBalancer is my new favourite network traffic monitor. It displays network bandwidth usage per process. The concept is similar to NetLimiter. The difference is that the free version of NetBalancer allows setting the limits to processes. I don't usually use this functionality.

Google Reader migration

So, many seem upset about Google Reader shutting down, and worked up with migration of their feeds to somewhere better.
My current take is Opera browser. It has a built-in RSS feed reader. The reader has a good performance and offers plenty of options I'd expect from a decent feed reader. Another benefit is that it comes with Opera so no extra software to install. Import and export of OPML is a breeze.
So the trial starts.

  • sync across devices/instances
  • Android version
  • no external dependencies

Opera browser beta - Android Apps on Google Play

Opera Beta is out! While I'm enjoying the current Opera Mobile browser, the beta version is a step ahead, showing the upcoming features. Plus, it is a great opportunity to send feedback and contribute to that great piece of software.
Here are some of the pros of Opera Mobile, from my perspective:
  • Text reflow- When zooming in and out, the default option is to reformat the text. So, even when you zoom in on a page, all the text is still displayed so no scrolling is needed. This is just brilliantly implemented.
  • Excellent zoom in/out - I find it very convenient to zoom in with double tap, and go back to full page the same way. 
  • Progress bar - I like the way loading progress is indicated in the address bar, reusing the space and showing how long until all the content is loaded.
  • Full screen view - There is an option to show browser in full-screen view, hiding the Android status bar. Status bar is useful at times and it is quite easy to bring it back. This feature is great in combination with the one below...
  • Address bar hiding - Address bar goes away when you scroll the page down and comes back when scrolling the page up. Similar to default Android browser behavior. It would be great if the Android status bar would hide/show at the same time with address bar. More screen real estate could be used to display the page content.
  • Excellent log-in field matching - Finally a browser that properly matches log-in fields and this works on most pages I tried. I often had issues with other browsers, messing up fields and values.
  • Synchronization - Similar to Chrome, Opera synchronizes across all your browsers, desktop and mobile. 
  • Online access to sync data - The feature is called Opera Link and is also accessible online for access through a web browser - here. Quite convenient to access your bookmarks from a foreign device or PC.
  • Rendering quality - For some reason I just see less weird-looking pages on Opera than in other mobile browsers and the whole browsing feel is much more like browsing on desktop. 
  • Rendering speed - Rendering is just reliable and fast. 
  • Bookmarks that work - Unfortunately for Chrome, my bookmarks got screwed up after scrolling halfway through the list. Opera ones seem to work with even the larger amount of bookmarks, after importing the old ones plus adding new ones to the collection.
  • Show Image - a nice feature for pages where not the whole picture fits the viewing area. Long-tap on image and select "View Image" and it will open in a separate tab. Can be zoomed in and scrolled and analyzed for heart's content then.
  • Tab switching - I find this way of tab switching, with previews, just superior to anything else. Maybe the fact that the whole experience is *fast* contributes to the effect.
  • Integrated download manager - This is extremely convenient for sites that require authentication for download. Now downloading finally works properly! No need to use desktop just to download a file when authentication is required.
  • In-browser Notes - This is still something I'm getting used to but is very usefull and often needed. Especially when notes are synchronized with other devices.
  • Zoom-In when tapping multiple links - This is a great feature. When, while tapping, your finger touches multiple links, the browser will zoom in and mark the ones you touched. That way you can tap on the one you really want.
Notes on Opera Beta:
Opera Mobile Beta is the first version utilizing WebKit rendering engine in Opera browser. Now, this change caused a design overhaul so most of the features listed above look and feel different. The drawbacks:
  • No address bar hiding, nor status bar hiding.
  • No progress bar.
Note, however, that this still is *beta* software and things might, and should, change in the future.

Java (Applets) in Fedora 18

After some applets wouldn't run in either Chrome or Firefox on my Fedora 18 system, it was time for some investigation.
First I tried installing Oracle Java as some applets might be requiring it explicitely.

Oracle Java

Download Java from here. Follow the instructions for installing, from here.
Then, open "about:plugins" in your browser and check if the Java plugin is displayed there.

Verify Java installation here. Test applet support here or on JavaTester.
Remove old versions, as specified here.

While I first installed 32-bit version of Java, as suggested on Oracle's site, this is not correct. The proper version to install, even for applet support, is 64-bit, if on 64-bit system. After installing 64-bit version and setting it to be the active one, using 'alternatives', applets worked in both browsers!

Set default file handlers from Nautilus, Fedora 18

To set the default handler for file types do the following:
