QtCurve faster than the rest?

Wednesday, June 16th, 2010

I have an EeePC 1201n that has a pretty descent graphics processor (Nvidia Ion), but I was still noticing a little bit of sluggishness with KDE’s KWin desktop effects enabled.  Things like minimizing or switching desktops produced minor little hiccups.  Overall, it was still fast, but it was enough to make me try some different settings.

I happened to like QtCurve (style and window decorator) anyway, so I compiled the latest version and installed it.  As soon as I started using the window decorator, replacing the default Oxygen one, poof, instant speed.  The response time is excellent with absolutely no hiccups at all.  Is QtCurve just that much faster than Oxygen, or did building it from source specifically for this hardware make enough of a difference to increase the speed?

Either way, it is smooth sailing from here on out.

Beautiful HTML5 Video Demo

Sunday, May 30th, 2010

HTML5 video will hopefully soon replace Flash Player as the video streaming method of choice for websites.  YouTube, Vimeo, DailyMotion, and others are currently providing beta examples of their future HTML5 video players.  While these demos are OK, they do not really showcase how beautifully seamless the experience can be.

SublimeVideo does just that.  It feels like you are watching an HD video from a Blu Ray drive on your computer.  If you have an HDMI out on your laptop, you could display it on your TV, and it would be picture-perfect.  Flash never functions exactly like native video, and it hogs CPU and RAM.  Anyone with dual monitors like me knows that playing Flash in fullscreen is a pain as well.

HTML5 video requires no additional browser plugin, and the webmaster has the freedom to customize the interface and fullscreen support (which is built in to browsers anyway).

To view the video, you will need the latest release of Safari (v4.0.4+), Google Chrome (v4.0+), or Firefox (v3.6+).  It also works with Internet Explorer with Chrome Frame installed.

The iPad hype and why books are safe

Friday, April 9th, 2010

There has been much talk about the cybersphere with the release of Apple’s new iPad.  Some of that talk has reflected the views of people who believe the days of print materials are numbered.  And please don’t mistakenly assume that because I am a librarian, I would shed tears over such a loss.

From the perspective of historical preservation, appreciation of literature, and a general love of books, I would certainly miss holding a book in my hand — the smell and texture of the pages, the feeling of turning each one with my fingers, and the weight of the object in my hand.

Nevertheless, I recognize that a change must come.  Printing anything on paper is destroying our environment, the only earth we have. Something must replace the traditional book, but the real question here is whether e-book readers like Amazon’s Kindle or over-glorified e-book readers like the new iPad are the answer to this dilemma.  I think not.

There are two main problems with this theory.  The first is cost.  While there may be future devices that are inexpensive and easily distributable, these devices are not.  As much as Apple fanboys would have you believe that everyone and their mama is going out to buy an iPad, that simply is not the case.  If people have to pay more or even as much for a reading device as they do for mobile service or cable television, people will simply stop reading.

The second problem is format.  Digital media is currently laced with poison (i.e. DRM).  It is a hassle that you cannot share your e-books with others as easily as you would shared a print book.  It is ridiculous that libraries cannot do this, and until they can, e-books will always be second-rate.  The format problem is also reflected in the devices themselves.  No matter how thin they get, they are not going to replace the look and feel of a real book.

I believe the real solution is something like I saw on Caprica: a page that looks and feels like paper but is electronic.  We have the ability to synthesize almost anything these days.  I am lactose intolerant but can eat soy cheese and hardly notice the difference.  Paper can be synthesized and so can book covers that are stronger and more resilient than the current offerings.  Imagine hold a book that looks and feels just like a real book, but you can press a button when you are finished reading and turn it into the book’s sequel.

I am not writing this because of nostalgia or my love of books but just based on my observation of library patrons and people in general.  I believe that until we reach the point where the benefits of e-books outweigh the inconveniences and high cost, print books are safe.

Ubuntu Java versions

Friday, February 26th, 2010

Just a quick note. I discovered that the Ubuntu Jaunty (9.04) version of sun-java6 provided in one of their updates is a higher version than the base version provided in Karmic (9.10). This produces installation errors if you try to add any additional Java packages.

The solution is to remove sun-java6 and its associated components and reinstall (You can also downgrade in Synaptic by using "force version" and selecting the Karmic version).

Proper USB Portage

Image of a mac with 70 USB ports

When will computer manufacturers finally get it right? For a serious computer user, four or even six USB ports is just not enough. In this day and age, I should not have to attach a HUB just so I can have all of my devices connected at once. Everyone is different, but let me give you an example of everything I need plugged in at once:

1. keyboard

2. mouse

3. graphics tablet

4. external hard drive

5. printer

6. game controller 1

7. game controller 2

Then, I need at least one free port for card readers and/or flash drives that I might attach. Is that really too much to ask? 8 to 10 ports on every desktop PC should be standard. A laptop should at least have four (I’m looking at you, Apple, with a disappointed expression on my face). It’s time to get it right. My computer should have more ports than an island nation, more ports than a submarine, more ports than…you get the idea. Four in the front and six in the back. That’s all I need.

KDE 4.4 and Tabbed Windows

Sunday, December 20th, 2009

KDE logo blue background with white KKDE 4.4 Beta 1 has been released, and the talk of the town is the new “tabbed windows” feature. They completely slipped this one past me. I didn’t even know anyone was working on it. Anyway, it is exactly what the name implies: the ability to have multiple windows all tabbed in one window. You can even drag one window onto another window’s row of tabs.

As a writer, I have long wished for tabbed word processing (outside of Google Docs), and now that will be possible with this KWin feature.

The Year of the Linux Desktop Mobile Phone

Thursday, September 17th, 2009

htc-magic-scaled
Since its creation, over fifteen years ago, free software and open source advocates have longed for the day when masses of people around the world would adopt GNU/Linux or Linux (depending on who you ask). There is little doubt that the past five years have seen tremendous strides in Linux desktop adoption.

Some hardware vendors, such as Dell, now sell Linux desktop computers, although you have to page through their online catalog to find it, and their promotion of it seems spotty at best. The netbook craze has also seen the rise of several Linux offerings, but even the company that arguably started the netbook craze with its Eee PCs, Asus, still proudly displays “Better with Windows” on their website.

How to Use Digikam to Export Photos to Flickr, PicasaWeb, and Facebook

Wednesday, September 16th, 2009

splash screen
Digikam is a free and open source photo management software package for KDE. Many KDE-based Linux distributions either come with Digikam installed or have it available in their repositories. With Digikam, you can import photos from your digital camera or flash memory, organize and tag them, rate them, edit them, and export them to various services or custom galleries.

Three popular services that Digikam can handle are Flickr, PicasaWeb, and Facebook. The first two are social photo sites, and the last is a social networking site. All three support photo plugins used by Digikam. This makes uploading photos quick, easy, and painless.

I am operating under the assumption that you already have accounts on the services you want to use. If not, you will need to register and activate whichever accounts you want before you proceed.

Nokia N900 Phone?

Thursday, August 27th, 2009

Nokia N900

The Web is buzzing about Nokia’s announcement of the next in the Nokia Nxxx series, the N900.  I found it odd that Nokia had chosen to make this version a phone when the previous three versions, the 770, N800, and N810 were all “internet tablets”.  The only reason I even believed this one would be a phone is because of all of the buzzing, with numerous tech news sources reporting it as Nokia’s new phone.

After looking at the website for the device for a few minutes this morning, however, I found absolutely no mention of it being a phone.  They have pictures of its interface but never show a dialing pad.  The specs mention mobile broadband but not mobile voice.

It does run the new Linux-based version of Nokia’s Maemo operating system, which will probably not be compatible with previous versions of the tablet, since this tablet will finally introduce a 3D graphics chip with iphone-ish effects (as if that’s important).

But no, it is not a phone, unless Nokia just really wants to minimize the significance of it being a phone.  According to Nokia’s own website, it is the “Nokia N900 mobile computer”.

UPDATE (2009-08-27): The features site now mentions “phone” as one of the features.  It actually looks pretty cool.  Let’s just hope they don’t tie customers to a 2-year contract with a crappy service provider like a certain other company who shall remain a nameless red fruit.
