Farewell, Xmarks Bookmark Sync!

Posted on September 30, 2010 by Kelson

It’s not a huge surprise, with all the major web browsers adding their own bookmark sync services, but Xmarks (formerly Foxmarks) is shutting down in January.

I figure I’ll just use Firefox Sync, Chrome sync, Opera Link, etc. to share bookmarks between the desktop and laptop, but what I really liked Xmarks for was its ability to sync different browsers together. I’m always switching between Chrome, Firefox, Opera and Safari (and occasionally IE when I’m on a Windows box) and it’s nice to have them all on the same set of bookmarks.

I guess it’s back to periodically exporting from my main browser and importing in the secondary ones, unless I find a tool or find the time to read up on the bookmarks formats and write one.

Android Browser Using Extra Space? Check Gears!

Posted on February 9, 2010 by Kelson

I finally found out what’s been taking up so much space on the Android web browser on my G1: Gears!

Whenever the low-on-space warning* icon shows up on the phone, I open up the list of applications. Then I sort it by size, look for the largest apps that I don’t use anymore, and start uninstalling.

“Browser” is always high on the list, but it’s all data. While I could free up the space by telling it to clear everything, I want to hang onto things like bookmarks. Each time the icon popped up, I’d go back to the app, open up More and then Settings, and clear the cache, or the history, or cookies**, one category at a time.

Then I’d go back to the App list and it would still be using up several megabytes of space.

Yesterday, it occurred to me to check the Gears settings. Months ago, I’d set up two WordPress blogs with Turbo mode, which uses Gears as a permanent cache for the admin area. It’s great on a desktop or laptop with lots of local space and a slow or flaky Internet connection. But it wasn’t helping me much, because…

  • WordPress Turbo Mode is only really useful if you use the rich-text editor, which I don’t.
  • On the phone, I rarely manage either blog through the browser anyway. I usually use WordPress for Android (formerly wpToGo).
  • The files it stores take up a whole megabyte — per blog! (possibly more, depending on how the file system stores them.)

So I removed both sites from Gears, along with a couple of other sites that I’d added, but didn’t need anymore, and freed up about 3 MB.

It should be a while before I see that low-space icon again, and I shouldn’t have to ration my installed apps quite so closely!

*This wouldn’t be a problem if they’d given the G1 enough memory for apps in the first place, or if they’d let us install apps to the SD card (where I still have gigabytes of free space), or if I were willing to root my phone, or if I’d just bite the bullet and buy a Nexus One.

**I’d really like to be able to selectively delete cookies — or rather, to selectively keep a few cookies and delete the rest — but that’s another issue.

Browser Sniffing Strikes Again!

Posted on May 27, 2009 by Kelson

As the first major web browser to reach a double-digit version, Opera has been testing out alpha releases of version 10 for months now. One of the early problems they encountered was bad browser detection scripts that only looked at the first digit of a version number and decided that Opera 10 was actually Opera 1, and therefore too old to handle modern web pages.

After extensive testing, they’ve concluded that the best way to work around this is to pretend to be Version 9.80. From now on, all versions of Opera will identify themselves as “Opera/9.80″ with the real version appearing later in the user-agent string.

For example:

Opera/9.80 (Macintosh; Intel Mac OS X; U; en) Presto/2.2.15 Version/10.00

This is similar to the way all Gecko-based browsers identify themselves as Mozilla/5.0, then list the real browser name and version number later on, which makes me wonder why they didn’t just stick with that increasingly irrelevant prefix — though I suppose any scripts looking specifically for Opera versions might have still picked up Opera/10 later on in the ID.

It’ll be some time before Firefox or Safari runs into this issue, but with Internet Explorer 8 in wide release, you have to wonder…what will Microsoft do when they get to IE 10?

Retroactive Robots Exclusion

Posted on May 21, 2009 by Kelson

In going through to-do items in my mailbox, I stumbled on this post which I thought I had posted here, but realized I hadn’t. It may be out of date, but it may prove interesting, at least to someone.

I recently [edit: August 2006] discovered exactly how the Wayback Machine deals with changes to robots.txt.

First, some background. I have a weblog I’ve been running since 2002, switching from B2 to WordPress and changing the permalink structure twice (with appropriate HTTP redirects each time) as nicer structures became available. Unfortunately, some spiders kept hitting the old URLs over and over again, despite the fact that they forwarded with a 301 permanent redirect to the new locations. So, foolishly, I added the old links to robots.txt to get the spiders to stop.

Flash forward to earlier this week. I’ve made a post on Slashdot, which reminds me of a review I did of Might and Magic IX nearly four years ago. I head to my blog, pull up the post… and to my horror, discover that it’s missing half a sentence at the beginning of a paragraph and I don’t remember the sense of what I originally wrote!

My backups are too recent (ironic, that), so I hit the Wayback Machine. They only have the post going back to 2004, which is still missing the chunk of text. Then I remember that the link structure was different, so I try hitting the oldest archived copies of the main page, and I’m able to pull up the summary with a link to the original location. I click on it… and I see:

Excluded by robots.txt (or words to that effect).

Now this is a page that was not blocked at the time that ia_archiver spidered it, but that was later blocked. The Wayback machine retroactively blocked access to the page based on the robots.txt content. I searched through the documentation and couldn’t determine whether the data had actually been removed or just blocked, so I decided to alter my site’s robots.txt file, fire off a request for clarification, and see what happened.

As it turns out, several days later, they unblocked the file, and I was able to restore the missing text.

In summary, the Wayback Machine will block end-users from accessing anything that is in your current robots.txt file. If you remove the restriction from your robots.txt, it will re-enable access, but only if it had archived the page in the first place.

15 years of the Opera Web Browser

Posted on April 28, 2009 by Kelson

Origin of Opera: Comic StripHard to believe Opera has been around for 15 years. It’s only 14 since its first release, but 15 years ago two programmers started the project that became the Opera web browser.

I’ve been using Opera off and on for about 10 years. I think it was 1999 when a classmate showed me Opera 3.6, and how fast and small it was. (This was back when the installer fit on a floppy disk — and back when that actually made a difference.) I’ve followed it as they expanded from Windows onto Mac and Linux, onto high-end cell phones with Opera Mobile, and finally onto every Java-capable phone with Opera Mini. I’ve watched as they went from trialware to ad-supported to freeware business models. And while the desktop browser is no longer the speed demon it used to be, it’s been a consistent innovator in terms of both browser features and web capabilities.

So I’d just like to say: Happy 15th birthday, Opera! Just think, in a year, you’ll be old enough to drive!*

Happy 15th Brithday, Opera!

*In California, anyway. I think in Norway the driving age is 18.

Upgrading the Web: IE8 Released

Posted on March 20, 2009 by Kelson

Internet Explorer.Microsoft released Internet Explorer 8 yesterday, for Windows XP and Vista. So if you’re still running IE6 it’s once again time to think about upgrading. (Assuming, of course, that you’re not locked in by corporate policy or another piece of software.)

IE6 is now two versions behind the current release.

IE6 is almost 8 years old (it was released in 2001).

IE6 is lacking in many capabilities that all other modern web browsers have, in web technology, in security, and in features you can use.

You can read a review at Wired, a write-up from the IE team, or a summary of technical changes from WaSP.

Of course, Internet Explorer isn’t the only option out there. There’s Firefox, Opera, Chrome and a host of other alternative browsers that are worth checking out.

If you’re still running Windows 2000 or some other old version of Windows that can’t run IE7 or IE8, I’d absolutely recommend Firefox or Opera. Either will be much better than IE6, both will run on Windows 2000, and Opera will even run on Windows Me and Windows 98 (but you really ought to move to something more current than Windows Me.)

Alternative Browser Alliance Update

Posted on December 13, 2008 by Kelson

Just a quick note: I finally got around to updating the Alternative Browser Alliance website. Not the full rewrite that I was planning to do two months ago, but at least it’s now current on things like Google Chrome, Firebug, Dragonfly, etc.

I’ve also released that site under the Creative Commons Attribution-Share Alike 3.0 license, which should simplify matters for translations.

Finally, as a compromise between a full blog and little notes on the home page, I added another Twitter account, AltBrowser, where I’ll post not just site updates but random bits of news, comments, tips, etc. related to the topic.  I don’t have time to maintain yet another blog.  And I’m not convinced the net needs one.

I still hope to do that major rewrite, but this should bring it mostly up-to-date.

Dillo Web Browser Updated at Last: 2.0 Release

Posted on October 14, 2008 by Kelson

After several years of inactivity and a quiet relaunch earlier this year, the Dillo web browser has finally released Dillo 2.0.

The open-source project started in 1999 with the goal of creating a small, fast, highly efficient graphical web browser that could run well even on low-end hardware and software. It’s a UNIX application, and runs on Linux, BSD, Solaris, etc. Things stagnated when it became clear that GTK1 was going to vanish, and GTK2 would not fit the project goals, and eventually the browser was ported to the Fast Light Toolkit (FLTK).

If you’ve used Dillo before, some of the improvements in this release are multiple character set support (the old versions were Latin-1–only), tabbed browsing, HTTP compression, anti-aliasing, improved rendering and UI, and smaller(!) memory usage.

It does have its limitations, and a few major items stand out as missing when compared to other modern browsers:

  • No CSS stylesheet support.
  • No scripting.
  • No plug-ins.
  • Limited SSL support.

That said, it’s useful to keep around on an older system, or for situations where speed is more important than rendering, or to test how a website works without styles, scripts, and plugins.

I started building RPMs of Dillo for my own use back in 2002, and became the official RPM packager for the project the following year. I’ve posted Dillo RPM packages for Fedora 9, RHEL 3, RHEL 4, and RHEL 5. Other distros will have to wait until I get my build system out of storage or figure out how to convince mock to let me build two packages together.

Suggestions Wanted: Alternative Browser Alliance Relaunch

Posted on September 24, 2008 by Kelson

You may have seen my website, the Alternative Browser Alliance. I put it together in 2005, when flame wars between Opera users and Firefox users were at their height, to show that we shared a common goal: opening the web. The most popular page on the site is a list of web browsers, which is linked as a resource from a number of sites and also gets a steady stream of traffic from people searching for alternative browsers.

Of course, things have changed a lot since 2005, so I’m planning an overhaul of the whole site. Continue reading →

First Impressions of Google Chrome

Posted on September 2, 2008 by Kelson

Now that it’s live, I’ve downloaded the Google Chrome beta on my Windows box at work.  Thoughts so far:

Good:

  • Site compatibility seems to be fine so far, with a couple of minor issues (see the “Bad” section).  Mostly I’ve tested it with a couple of forum sites, LiveJournal, Slashdot, and WordPress.
  • I like the simple settings box, with “Basics,” “Minor Tweaks,” and “Under the Hood.”
  • It does feel fast.
  • Showing the URL of links in the lower left-hand corner is a perfect compromise between the spatial advantages of a permanent status bar and the extra room provided by leaving it out.
  • I like the task manager for the browser itself.  It’ll be good for developers, but it’ll also be good for users: as the comic points out, if your browser starts chewing up all available resources, you’ll be able to tell what page/plugin/program is at fault instead of just blaming the browser.

Bad:

  • Gears support doesn’t seem to work quite right.  WordPress.com doesn’t detect that it’s available.  Local WP installs with Bad Behavior can’t sync completely.  (It doesn’t send an Accept header on the request for one of the TinyMCE files, which causes Bad Bahavior to think it’s a spambot and triggers a 403.)
  • Cookie management is too simplistic.  I like to accept all cookies temporarily, but clear everything when I end my browsing session, with exceptions for sites where I want to stay logged in.  This is easy in Firefox, a little trickier in Opera, and doesn’t seem to be an option in Chrome.
  • I have seen it pause a couple of times, with as few as 5 tabs. [edit: these seem to be related to Flash content]
  • No Incomplete spell-check.
  • I keep hitting the forward-slash key to search within a page, since that’s the shortcut I’m used to in Firefox and Opera.
Debatable:
  • The UI does indeed stay out of your way.  I guess this sort of makes Chrome the Anti-Flock.
  • DNS Pre-Fetching is enabled by default.  This is different from full HTTP pre-fetching in that all it does it look up the IP addresses of the links that you might click on.  It’s not clear at what point it does this — I don’t remember seeing it mentioned in the comic, which (ironically) isn’t searchable.  I suppose it could either hit the domains of all the links on a page, or just those that would trigger HTTP pre-fetching, or even just send the query when you hover over a link (to get a split-second head start before you click). Update Sep. 17: Google has a blog post explaining pre-resolving in detail. Apparently it does check the domains for all the links on the current page.
