VMWare Server, thanks!

posted Thursday, May 28, 2009 6:35 PM by hussain

For a long time I've used VMWare Workstation at home, even though I'd bought an x64 machine just for vms.  Lame, right?  C'est la vie.  I'd originally though I should install a hypervisor OS (ESXi, Xen) instead of the VistaBusiness I did install, but then got bored, put on VBx64 and was done with it.  Yesterday, I figured I'd look again at VMWare Server 2.01 (ESXi's free now, too, go figure).

Didn't take too long to uninstall VMWare workstation (via the console with the -c option) and install VMWare Server and now I have remote access to my newly headless x64 VMWare server.  Looks and works great!  The only thing I miss is being able to edit the virtual networks in the interface (which was done in Workstation's) - I have to login (remote desktop) into the box to do that.  Ah, tradeoffs.  I get much better info on the running vms themselves - cpu and ram usages.

I upgraded my Fedora Core 9 image to 10 (yes, I know 11's out in 12 days) and stuck irssi, screen, fah, and openldap on it and for a paltry 256mb (only using 128mb), I have a little unix testbed that makes me feel all warm and fuzzy.

I know summer's here already, but this is my spring cleaning, al Gore.

Amazon releases Swine Flu sequences

posted Monday, May 04, 2009 6:56 PM by hussain

Amazon has released Swine Flu Influenza Virus genomic sequences on their Public Data Sets. Now anyone with an Amazon machine image in the cloud can attach to it and use it for research and sequencing. Time to dust off phrap and phred? (dating myself)

Impressive.

I still don't know Linux - Kindle update 2.0.3 (327610024)

posted Friday, April 24, 2009 6:55 AM by hussain

This morning I was alerted that there was a new rev of the Kindle firmware coming - 2.0.3. It was, of course, a post on the user community MobileRead that did it. It's a testament to the user community (and to the Kindle's popularity) that there're fans rabid enough to tell eachother when a new firmware is out. Amazon has typically been very cryptic about what's actually in the firmware - they don't post release notes - but also very forthcoming in what's in it by posting the sources used.

Now, these aren't the sources to the Kindle's proprietary software, just the underlying open source OS changes. Still, clues can be divined from this, even if it's tasseomancy-style.

Downloading the latest source code release from Amazon,

The gplresults.tar inside - this is the tarball for the release - was dated 4/14 for a drop downloaded this morning.

Initial cursory comparison shows the dates on 31 files changed from 03/06/2009 for the 2.0.2 (309510017) release vs the 04/14/2009 for the current. I'll get around to looking at the linux-2.6.22-lab126 changes in more depth, like I did last time in I don't know Linux - Kindle update 2.0.2 (309510017).

Other than the date, + indicates increase in filesize from 2.0.2, - decrease in filesize: + alsa-lib-1.0.13_patch.tar.gz, - alsa-utils-1.0.13_patch.tar.gz, - busybox-1.7.2.tar.bz2, - dosfstools-2.11.tar.bz2, - e2fsprogs-1.38_patch.tar.gz, - klibc-1.5.tar.bz2, - linux-2.6.22-lab126.tar.bz2, - procps-3.2.7_patch.tar.gz, - taglib-1.5.tar.bz2, + uboot-1.3.0-rc3.tar.bz2, - udev-112.tar.bz2,

Twitter dates

posted Sunday, April 12, 2009 8:36 AM by hussain

Twitter's REST timelines (public, friends, users) return created_at dates in a way C# can't natively parse, so they have to be reformatted. Apparently, this format is whatever comes out of Ruby. Here's my solution, elegance not included.

public static string ReformatTwitterDate(string twitterDate)
{
// twitter date: "Sat Apr 11 05:22:54 +0000 2009"
// DateTime.Parse()'able date: "Sat, Apr 11 2009 05:22:54 +0000"
MatchCollection c = Regex.Matches(twitterDate, @"\w+");
return string.Format("{0}, {1} {2} {7} {3}:{4}:{5} +{6}", c[0], c[1], c[2], c[3], c[4], c[5], c[6], c[7]);
}

... or (without regexp) ..

public string ReformatTwitterDate2(string twitterDate)
{
string[] c = twitterDate.Split(' ');
return string.Format("{0}, {1} {2} {5} {3} {4}", c[0], c[1], c[2], c[3], c[4], c[5]);
}

And yes, they know the Search API's date format is different.

Kindle, USGovt, Afghanistan

posted Friday, March 20, 2009 11:33 AM by hussain

As I was getting ready for work today, I had the Kindle read to me the top article in today's WSJ, "U.S. Courts Former Warlords in Its Bid for Afghan Stability". I had also been contemplating also writing another "Six Degrees of Bin Laden" with the Haqqanni movement as that's making some news and it's a game I invented but then I heard Kindle robot TTS voice read this quote* and it struck me.

"Every politician in Afghanistan is a thief, but our governor doesn't take all the money for himself. He is building our city," says Shafeeq Azizi, a 37-year-old shop owner in Jalalabad. "Why does it trouble me if he gets rich?"

Mr. Azizi was lounging with friends in one of the Jalalabad parks restored by Mr. Shirzai's administration. Across the street is a park Mr. Shirzai built for women. A few miles away stands Shirzai Stadium. There's a new mall, new stoplights and refurbished mosques in many neighborhoods.

Critics say the governor's strengths and weaknesses are often one and the same. "He wants something and he says, 'Build it.' There is no plan," said Haji Wahid, who owns a construction company. He says he sees no long-term vision behind Mr. Shirzai's rebuilding efforts.

Parts of the US Government are tribal.

And not in any good connotation. Particularly our government's IT divisions. They're not just protected, entitled fiefdoms, an analogy whose European roots softens the devastation and criticism that it should bring, but actual tribal land grabs by people who have no idea what effective IT means but think they do because they can use a Blackberry like Obama or love their iPhone.

Here's how it should run. And by "it" I mean the Afghan situation and not our government IT's situation, since that's well in hand by people who think they know what they're doing, puls Web 2.0 ftw, data transparency and Vivek Kundra's back on the job. (Petty "warlords" watch out.)

When analysing situations like this a review of history's always helpful. Here's one slice of history that looks like it might be applicable: The aftermath of the British Raj and the subsequent upheaval in India and Pakistan eventually leading to an India where large wealthy families (Tata, etc) control multiple industries in a monopoly grip. The latter half of that statement resembles the US with our monopoly-families, too, which should give some indication where I'm going here. Granted, in both Iraq and Afghanistan (and most elsewhere), we - America - are not colonialists like the Brits, French, Germans, Dutch, etc and I'd argue our methods are less damaging, but that's another debate and another post.

The process at hand is this:

Tribal succession -> Tribally appointed, Elections -> Elections where Tribal relationships may still have sway -> "Free and Fair" Elections.

In the western world we may think we're so far advanced that we don't deal with fiefdoms anymore - we're beyond that process and that management style is retrograde or deprecated. It's not, we (westerners) just don't do it any more nor do we do it well. They (middleasternerners) do. There may be a value judgment in saying one style is better than another and I'll leave that up to someone's masters/phd thesis, but one fact is true: "Democracy" and "tribal consensus rule" don't interface well at an economic point. It's much better to have two democracies (or political structures loosely framed around democratic principles) interacting than disparate political systems (china-us, etc.). To this point, if we or for that matter Afghanistan, themselves, want to get to a more "democratic" style of political system, they'll have to go through the above transitional phases and we'll have to honor and recognize that those phases will happen. Whining (from western governments and western NGO "democracy watch dogs") does not and will not help phase transitioning, it'll just be annoying.

Currently tribal succession is in play. We'll have to let it happen. For example, the Jamal Baba Construction Co., part owned by Mr. Shirzai's son, Jaan Agh mentioned in the article will have to undergo economic pressure and engagement to become a company that has influence in the region. That'll allow external democratic organizations (whether external to Kandahar and Nangahar provinces or external to Afghanistan) exert some influence. The influence could be democratic-leaning or possibly Talib-leaning. That pressure, if properly exercised, will lead to another political round wherein the region'll be able to assess the benefits of a more open economic and political model and then continue down the tribal-democratic spectrum. Note India's example - Tata, Mittal, etc are all still in place, mostly unregulated from a monopoly stance - India's still not at "free and fair." One could also argue that Japan's kiretsus haven't reached the fullness of the "democratic" spectrum yet, either, after their rebuilding. Some countries don't want to go all the way and we should recognize and accept that. Will we, though?

Sony & Google Team up for Public Domain books

posted Friday, March 20, 2009 6:53 AM by hussain

There're sources for public domain books out there - Project Gutenberg and Manybooks, the latter of which supplies them in many formats - but no one's as large as Google, period. Now, as many outlets have reported, Sony & Google have teamed up to release public domain e-books in the ePub format from http://books.google.com/ (Google Blog Post).

This is a huge win for all readers, including the Kindle, even though it might not seem so right away. Granted, the ePub format isn't supported directly by the Kindle. That can be corrected by a future software push if Amazon wishes, but until then there are free software alternatives to convert ePub to the Kindle's mobi format. Software like Calibre, a pretty full featured ebook manager/converter will do, although I prefer my own Kindle Converter which sits on top of the mobigen command-line converter.

http://books.google.com/books?q=subject:"+Science+Fiction+"&rview=1&as_brr=1
That as_brr=1 is "Full View Only" in a search and that indicates public domain books.

The big difference between Project Gutenberg and Google (apart from Google's ~500k scans vs. PG's ~100k) is that Project Gutenbergs's have been proofread. Google's docs have typos!

I don't know Linux - Kindle update 2.0.2 (309510017)

posted Tuesday, March 17, 2009 9:20 PM by hussain
Although I'm still waiting to get pushed the 2.0.2 update, I thought I'd take a look at the linux sources.

Looking at the published gnu linux kernel sources provided by Amazon, only 4 files are different:

arch/arm/mach-mx3/dvfs_v2.c
arch/arm/plat-mxc/isp1504xc.c
arch/arm/plat-mxc/wdog.c
sound/arm/mxc-alsa-pmic.c

These are the kernel (2.6.22) mods from the last Kindle version, 2.0.1 (303870012).

Until Amazon posts release notes, we won't really know what was different in the functioning of the Kindle software, but the kernel changes look like adding in a counter to reboot (6 times) and setting the minimal soundchannels to 2.

Most of my software life I've tried to avoid linux or, rather, learning too much about it.  So, when I say I don't know Linux, that's my story and I'm sticking to it.

This is the contents of the Kindle src 2.0.2 309510017 release.

Amazon, DMCA, DRM and Mobileread

posted Monday, March 16, 2009 12:22 PM by hussain

Mobileread, a user-driven site that assists e-book enthusiasts access to public-domain knowledge around existing ebooks and ebook reader community support, has a series of wiki pages that describe how to use all sorts of devices and user-supplied support programs.

There are many sources for e-books and many formats. One of the most popular, and the one relevant to this article, is the Mobipocket format. Mobipocket is a format of e-book produced by the Mobipocket company, now owned by Amazon. E-book providers, other than Amazon, use the Mobipocket format, notably OverDrive, a large technology supplier for public libraries around the country. Some public libraries that use the Mobipocket OverDrive DRM (OD) allow their users to "check out" e-books and read them, typically with Mobipocket desktop software.

One of the support utilities described on the Mobileread site was called kindlepid.py, a Python-language script that displayed an e-book reader's device Personal ID (PID) created by Igor Skochinsky in 2007 when the Kindle version 1 was released. This PID is used to encode DRM-secured e-books from other vendors, whether it's OverDrive-enabled libraries or other public sellers. Amazon Kindle users who want to view DRM-protected e-books from these vendors can use their Kindle's PID to "fix" e-books so that they're able to be read on the Kindle (or, for that matter, their iPhone/iPod Touch with the Amazon Kindle app).

Mobileread, the user-driven site, had step-by-step instructions on how to download, install and use kindlepid.py to obtain a device PID. This script does not break, hack, crack, or remove the DRM from an e-book in any way but obtains the PID that's on the device. It enables legally purchased e-books to be read these e-books on legally purchased e-book readers.

The "fixing" part is enabled by another, separate, software script that was also described on the Mobileread site which utilizes the PID, kindlefix.py. This shifts the location of the PID in the DRM'd e-book file so that the Kindle (or iPhone Kindle app) can find it.

Amazon seems to have an issue with the kindlepid.py script and sent the owners of Mobileread.com a Digital Millenium Copyright Act (DMCA) "take-down" notice: asking Mobileread.com to remove references to kindlepid.py from their site, but not specifically with the kindlefix.py script.

Individuals posting on the Mobileread forms about this topic suggest that, since the kindlepid.py script has been around since 2007, Amazon is noticing this script now due to their release of the Apple iPhone/iPod Touch version of their Kindle reader. Additionaly, Amazon has removed "My Serial Number" which displayed a user's Kindle serial number from the "Manage My Kindle" page on their site around the same time that the iPhone/iPod Touch app was released. Posters also suggest that it's evidence that Amazon wants to control the origin of purchase and that this restriction of control may constitute a monopoly by preventing competition in the distribution channel. It was pointed out that Amazon's actions aren't restricting the publishing (that's already been covered by Amazon's assumed agreements with the publishers to DRM publisher's works and distribute them), but only where you obtain e-books from - only Amazon, not libraries or other vendors, such as BooksOnBoard and others.

Other posters take the angle that Amazon is attempting to preserve their relationship with publishers now that a Kindle app for the iPhone exists - preventing iPod owners who aren't entitled to buy from the Amazon store from using the app to read OverDrive or other vendor's DRM books. (#156, #158, #159) In light of the Author's Guild's issues with TTS and other e-book advocates' calls for support of formats other than Mobipocket, such as ePub, this line of thinking also seems logical.

And additional point that has been made by Kindle/Amazon watchers is that Amazon has been following an Apple-like trajectory for their product: from the exclusivity of distribution channel (iTunes store) to the DRM issue. Now that Apple's making a DRM-free iTunes store, some are wondering when Amazon's going to catch up. Catch up, at least with e-books, since Amazon already offers DRM-free mp3's for sale. Similar to the cycle of iTunes updates that "broke" hacked ("jailbroken") iPhones and iPod Touches, will Amazon look at the contents of a user's Kindle and remove any shifted DRM e-books? Amazon's Terms of Use for the Kindle states that Amazon can look into any Kindle and with their Whispernet connectivity possibly even update the firmware on the device to use a different DRM scheme and replace the DRM on DRM-protected e-books.

Is Amazon wielding the DMCA in "bad faith" in this situation? Is it even a proper use of the DMCA? Since neither the site or the scripts don't actually violate the DMCA, what's Amazon doing throwing it around?

Many long time Kindle advocates that frequent the forums are getting very discouraged at the "take down" notice that Amazon presented to Mobileread and are beginning to lose their enthusiasm for the product that made Kindle owners some of the most fervent supporters and source of free marketing. Some have even gone so far as to say they're no longer supporting Amazon, itself, which speaks to the wider issue of loss of customer loyalty. On the forums, disappointment ranges from expressing the feeling of loss of rights (feeling criminalized by reading library books), Sony e-reader owners breathing a sigh of relief feeling like they've chosen the correct device, to people considering dumping/returning their Kindles and purchasing an iLiad or waiting for another e-reader device such as the Wizpac Txtr.

From my personal experience as a Kindle 1 and Kindle 2 owner, I've loved them both, not just because I had portable reading device and not just because the screen is clear, but because I could put my own personal documents and personally converted documents onto the Kindle and the access to the Amazon Kindle store. The combination of personal freedom and access to a large existing market is what makes this device special to me and special enough to show off to anyone who's asked.

There are now several articles on this issue as well as a blog started by a Mobileread user, Dear Jeff Bezos.

App-a-Weekend: Kindle PID

posted Saturday, March 07, 2009 11:28 AM by hussain

In order to buy DRM'd ebooks from ebook retailers other than Amazon and load them onto your Kindle, the first thing you need to do is obtain your Kindle's Personal ID (PID).

Mobileread.com has a great wiki about all things Kindle including a walk-through of how to use Python and Igor Skochinsky's python scripts to obtain your Kindle PID, if you know you Kindle's serial number (obtained by looking at the side of the box). Here's their walkthrough wikipage (xp, vista).

This weekend, I made a quick Windows UI that executes Igor's python scripts:


The Kindle PID app, PID tab


The Kindle PID app, Fix tab


File > Preferences


Aboot dialog, showing that Python and scripts are available.



App example (dummy serial used)

Installation is as follows:
  1. Install Python 2.61 msi
  2. Download Igor's scripts, place them somewhere you can remember (I placed them in C:\Software\dev\igorsk)
  3. Download and run Kindle PID

The app is very simple (a zipped exe), no installer. Feedback is welcome!

Edit:
1.0.2.1 03/09/2009
- Updated for v0.2 of igorsk's py scripts
1.0.2.0 03/09/2009
- Added PID generation for iPhone/iPod Touch
1.0.1.0 03/08/2008
- Added Kindle Fix utility

App-A-Weekend: Say This

posted Sunday, February 22, 2009 6:03 PM by hussain

I'd previously read, on my Kindle, in the Wall Street Journal, about the Author's Guild's objections to the Kindle2's new text-to-speech feature which allows reading of books to the user.

"They don't have the right to read a book out loud," said Paul Aiken, executive director of the Authors Guild. "That's an audio right, which is derivative under copyright law."

My immediate thought was that moms and dads all over the world are flagrant abusers of copyright and I couldn't imagine an author objecting to someone reading their book, out loud, in private.

Lots of good arguments have been made about this, from audio book production being well worth paying for, and generated voices - advancing as they have been - are nothing like real voices, to Windows and Macs having this ability for decades and, of course, the existing software for disabled readers, so I need not repeat them. Here's my argument: it took me a few minutes to write this app.

Aiken quote, as read by Microsoft Anna via SayThis: SayThis_Aiken.wav

This was an unintended application created after reading New Kindle Audio Feature Causes a Stir, WSJ, 02/10/2009 and E-Book Rights Alert: Amazon's Kindle 2 Adds "Text to Speech" Function, Author's Guild Blog, 02/12/2009.

A New Kindle?

posted Tuesday, February 10, 2009 6:54 AM by hussain

Is it horrible that I want an 2nd Kindle now that they've announced a new, 2nd generation one?

Where's the replaceable battery and the SD expansion? I suspect with all the new features, those won't be missed:

  • Display: 6" diagonal E-Ink® electronic paper display, 600 x 800 pixel resolution at 167 ppi, 16-level gray scale.
  • Size (in inches): 8" x 5.3" x 0.36".
  • Weight: 10.2 ounces.
  • System requirements: None, because it doesn't require a computer.
  • Storage: 2GB internal (approximately 1.4GB available for user content).
  • Battery Life: Read on a single charge for up to 4 days with wireless on. Turn wireless off and read for up to two weeks. Battery life will vary based on wireless usage, such as shopping the Kindle Store and downloading content. In low coverage areas or in 1xRTT only coverage, wireless usage will consume battery power more quickly.
  • Charge Time: Fully charges in approximately 4 hours and supports charging from your computer via the included USB 2.0 cable.
  • Connectivity: EVDO modem with fallback to 1xRTT; utilizes Amazon Whispernet to provide U.S wireless coverage via Sprint's 3G high-speed data network (check wireless coverage). See Wireless Terms and Conditions.
  • USB Port: USB 2.0 (micro-B connector) for connection to the Kindle power adapter or optionally to connect to a PC or Macintosh computer.
  • Audio: 3.5mm stereo audio jack, rear-mounted stereo speakers.
  • Content Formats Supported: Kindle (AZW), TXT, Audible (formats 4, Audible Enhanced (AAX)), MP3, unprotected MOBI, PRC natively; PDF, HTML, DOC, JPEG, GIF, PNG, BMP through conversion.
  • Included Accessories: Power adapter, USB 2.0 cable, rechargeable battery. Book cover sold separately.
