My primary computer is a dual 2GHz PowerMac G5 until I can upgrade it with a Nehalem Mac Pro, most likely around the end of the year or early next year. I bought it in 2004, along with a 23″ Apple Cinema HD (the old pinstripe plastic bezel kind with an ADC connector). Unfortunately, about a year ago the CCFL backlight on the monitor started turning pink from old age, and thus unusable in a properly color-managed photographic workflow.

I used that as an excuse to splurge on a humongous (and agoraphobia-inducing) HP LP3065 30 inch LCD monitor after reading the glowing reviews. The two features that sold me were the enhanced color gamut (the only way to improve that would be to get a $6000 Samsung XL30, something I am not quite prepared to do), and the fact it has 3 built-in DVI ports, so it can easily be shared by multiple computers (assuming they support dual-link DVI, which unfortunately my basic spec Sun Ultra 40 M2 does not). The fact it was 25% less expensive than the Apple 30″ Cinema Display helped, of course.

About 6 months ago, I discovered there was a fine pink vertical line running across the entire height of the monitor, roughly 25 centimeters from the left. Since I primarily use that monitor for photo (the primary monitor for Mail, web browsing or terminals remains the Apple), at first I worried there was a defect with my camera. I managed to reproduce the problem with my MacBook Pro (they have dual-link DVI, unlike lesser laptops), and called HP support (the 3 year HP warranty was also an important consideration when I purchased).

My first support call in November 2007 went well, and the tech told me I would be contacted to arrange for an on-site exchange. This is a seriously heavy monitor and I did not relish the idea of lugging it back to FedEx, so getting premium support for a business-class monitor sounded an attractive proposition. Unfortunately, they never did call back, and as I had other pressing matters to attend to involving international travel, I just put it out of my mind (it is a very subtle flaw that is not even always visible).

I only got around to calling them back a few weeks ago. Unlike in November, I was given the run-around with various customer service reps in India until I was finally routed to a pleasant (and competent) tech in a suburb of Vancouver (the US dollar going in the direction it is, you have to wonder how much longer before HP outsources those call centers back to the US). The problem is not with Indian call centers, in any case, all but one of the CSRs were very polite (I suspect Indians learn more patience as they grow up than pampered Americans or Europeans would). The problem is poorly organized support processes and asinine scripts they are required to go through if they want to keep their jobs. In any case, the Canadian rep managed to find the FRU number and also told me someone would call to schedule an appointment. Someone did call this time, to let me know the part was back-ordered and they would call me when it becomes available.

This morning, as I was heading for the shower, my intercom buzzed. It was a DHL delivery man with the replacement monitor. I had to open the door to him in my bath robe. Naturally, nobody at HP bothered to notify me and had I left earlier, I would have missed him altogether.

One of the great things about Apple products is that if you live near an Apple store, you can just stop by their pretentiously-named Genius bars and get support for free (though not free repairs for out-of-warranty products, obviously). I now have a fully working HP monitor again, so I suppose I can’t complain too loudly, but the Apple monitor with the sterling support looks like the true bargain in hindsight.

I installed Adobe Creative Suite 3 on my home PowerMac and my MacBook (the license allows you to install it on two computers as long as they are not in simultaneous use). The only real reason I upgraded is to get a native Intel version. I have barely started using it already and I already have peeves:

• Bridge looks butt-ugly, is even slower than before and with a more amateurish interface than ever
• The install procedure is incredibly annoying and Windows-like. There is no justification for an install procedure that chokes if the beta was not uninstalled officially (although I have to give some brownie points due to the fact the cleanup script is written in Python).
• The icons are aesthetically bankrupt. What kind of credibility does Adobe think it has with creative people with such an astoundingly lackluster effort?
• Barely installed and already in need of software updates. The widespread availability of fast Internet connections is no excuse for shoddy release management or a “we’ll patch it post-release” mentality. Speaking of which, the only proper time to interrupt users with a software update dialog is as they are quitting the application, not by getting in the way of whatever task they are trying to get done by starting up the app.
• Don’t clutter my hard drive with legal drivel in twenty different languages. It’s called “Creative Suite”, not “Boilerplate Suite”.
• All the tie-ins to paid add-on services like Adobe Stock Photos or Acrobat Conferencing are incredibly obnoxious, just like those for MSN or .Mac.
• JavaScript in Acrobat is a big security and privacy risk, and should be disabled by default.
• On the plus side, thanks for making a “Design Basic” edition without all the despicable Flash garbage in it. I would actually pay more for the Basic version than for the supposedly premium one infected with Flash and Dreamweaver.

Update (2008-01-01):

It seems Adobe has also crossed a serious ethical line by building in spyware to track on whenever a user starts a CS3 application.

As far as I am concerned, this is the last straw and I will actively start looking for substitutes for Adobe products as soon as I return from my vacation.

Update (2008-01-02):

It seems Adobe does not collect the serial number after all. The apps should nonetheless never call on the Internet except possibly to check for updates. For people like myself who have static IPs, the IP address itself could be used to correlate the analytics with personal information.

As far as I can see, the answer is yes.

About a month ago, my two-year old Windows PC game machine started crashing every two minutes in NWN2. This proved the last straw, and I decided to upgrade. One of the games I have, but seldom play is Oblivion, which is graphically gorgeous, but chokes on anything but the most powerful hardware at ordinary resolutions, let alone my Apple Cinema Display HD’s 1920×1200, and cutting-edge video cards are no longer available for the AGP bus in any case.

I looked around for packaged solutions from systems integrators, specialized gaming PC companies like AlienWare, and Dell. Contrary to conventional wisdom, it is still much cheaper to build a PC from components than to buy one from a major vendor, $1500 vs. $2500 minimum. Part of the reason is that the vendors flag anyone wanting the absolute best video card as a “cost is no object” customer, add all sorts of expensive components that make no sense in a machine that will only ever be used for games, like fancy DVD burners or flash card readers to jack up the profit margins. As if anyone in his right mind would use a Windows computer for serious work like digital photography…

My configuration is the following: a relatively quiet Antec Sonata II case, an Abit KN9 Ultra motherboard, an AMD Athlon x2 5200, 2GB of Kingston DDR-800 RAM, a humongous nVidia GeForce 8800GTX video card, a 500GB hard drive and a basic DVD-ROM drive.

When it came to choosing the OS, after much trepidation I opted for Vista Home Premium because the 8800GTX is one of the few cards that support DirectX 10, which is a Vista-only feature. I knew Vista would embezzle half the processing power of one core in DRM code that is actually working against my interests, but then again nobody in his right mind would use DRM-ed formats, whether Microsoft or otherwise, to store their music library, so the damage would be limited. Also, Vista comes with “downgrade rights” which allow you to legally install the previous version of Windows.

Vista comes in an attractive copper-colored DVD that is actually quite elegant. Its color scheme is also far superior to the molten Play-Skool set monstrosity that is XP. When I started the Vista installer, I was pleasantly surprised by how quickly it dealt with hard drive formatting (the previous Windows I installed myself is Windows 2000, which will insist on a time-consuming full format instead of the quick format used by the XP or Vista installers). The good impression lasted for all of five minutes. After the inevitable restart to complete installation, the screen promptly dissolved into a scrambled red-and-white screen of doom (I did glimpse a blue screen of death shortly before it rebooted). The diagnostics were completely unhelpful, as could be expected. When the operating system cannot even install itself, you have got to wonder…

Dejectedly, I fished out a Windows XP install DVD. it would not accept the Vista serial number. So much for downgrade rights. Of course, since the package was now opened, no hope for a refund either. I ended up buying a copy of Windows XP, which installed without a hitch. Of course, I still had to install the video drivers, but it did not crash half-way through the install procedure. And Oblivion is now playable without agonizing stutters every two paces.

The 8800GTX is very recent hardware, which did not even have non-beta Vista drivers when I installed it, so I could understand the OS falling back to SVGA mode. There are no other really exotic components here, certainly nothing than XP SP2 could not deal with and therefore Vista should as well. The machine is also well within the recommended minimum configuration (although some experts now advise 4GB of RAM as a realistic minimum for Vista). Crashing during install, when a five year old OS like XP handles it just fine, is simply unacceptable in my book. Even Solaris 10 Update 3, an OS notorious for its limited hardware support, installed without a hitch. Despite the ten man-millennia Microsoft invested in this lemon, they apparently could not be bothered to test the installer.

Conclusion: unless you buy a computer with Vista pre-installed, avoid it like the plague until SP1 is out, just like Intel.

Post scriptum:

Actually, I would not even recommend a PC with Vista preinstalled, as it has terrible backward compatibility. It will not run Office 2000, which is what my company has, for instance. Joel Spolsky has an excellent article on how the new, bloatedly bureaucratic Microsoft lost its way by sacrificing backward compatibility on the altar of useless marketectures. Perhaps they are just trying to force-upgrade people to Office 2007. They should beware: unlike 2002, people have credible alternatives now.

Update (2007-08-30):

The paper about how Vista eats up CPU on DRM has been criticized by the generally reliable George You. My point about the inability to even install on a modern machine that XP has no problems with remains. In any case, having the operating system constantly eat up CPU on tasks I do not want it to, whether it is 7% or 100% of one core, is still morally no better than a parasitic botnet.

Cartoons can be the most subversive of genres. The Simpsons has been serving acerbic social commentary from deep within the bowels of the reactionary Fox network for over 10 years, yet they manage to stay fresh when other, more edgy shows like Family Guys struggle for relevance.

One of the main characters in Futurama, Matt Groening’s other animated show, is named Turanga Leela, a transparent reference to Olivier Messiaen’s Turangalîla Symphonie. The number of people who have even heard of this fairly esoteric work is quite limited, and those who actually like it (as opposed to professing admiration for it out of conformity) can probably be counted on the fingers of one hand. Thus we have established that Groening or his staff are intimately familiar with 20th century classical music.

Last week’s episode of The Simpsons featured the US Army showing a recruitment commercial at the Simpson kids’ school. It starts with a rousing martial score. I have extracted a 4MB clip of the scene (Quicktime 7 required) for those who missed it.

The piece in question is from Prokofiev’s Alexander Nevsky cantata. The music was composed for the epnymous anti-german propaganda movie by Eisenstein (although, in a little known consequence of the Molotov-Ribbentrop pact, Stalin made Eisenstein produce Wagner’s Die Walküre for the Bolshoi in atonement for the newly inconvenient Nevsky). The lyrics heard can be translated in English as follows:

Arise, ye Russian people,
to glorious battle, to a battle to the death:
arise, ye free people,
to defend our beloved country!
All honour to the warriors who live,
and eternal glory to those slain!
For our native home, our Russian land,
arise, ye Russian people!

Needless to day, the delicious irony is unlikely to be mere coincidence.

I use Adobe Photoshop CS2 on my Mac as my primary photo editor. Adobe recently announced that the Intel native port of Photoshop would have to wait for the next release CS3, tentatively scheduled for Spring 2007. This ridiculously long delay is a serious sticking point for Photoshop users, specially those who jumped on the MacBook Pro to finally get an Apple laptop with decent performance, as Photoshop under Rosetta emulation will run at G4 speeds or lower on the new machines.

This nonchalance is not a very smart move on Adobe’s part, as it will certainly drive many to explore Apple’s Aperture as an alternative, or be more receptive to newcomers like LightZone. I know Aperture and Photoshop are not fully equivalent, but Aperture does take care of a significant proportion of a digital photographer’s needs, and combined with Apple’s recent $200 price reduction for release 1.1, and their liberal license terms (you can install it on multiple machines as long as you are the only user of those copies, so you only need to buy a single license even if like me you have both a desktop and a laptop).

There is a disaffection for Adobe among artists of late. Their anti-competitive merger with Macromedia is leading to complacency. Adobe’s CEO, Bruce Chizen, is also emphasizing corporate customers for the bloatware that is Acrobat as the focus for Adobe, and the demotion of graphics apps shows. Recent releases of Photoshop have been rather ho-hum, and it is starting to accrete the same kind of cruft as Acrobat (to paraphrase Borges, each release of it makes you regret the previous one). Hopefully Thomas Knoll can staunch this worrisome trend.

Adobe is touting its XMP metadata platform. XMP is derived from the obnoxious RDF format, a solution in search of a problem if there ever was one. RDF files are as far from human-readable as a XML-based format can get, and introduce considerable bloat. If Atom people had not taken the RDF cruft out of their syndication format, I would refuse to use it.

I always scan slides and negatives at maximal bit depth and resolution, back up the raw scans to a 1TB external disk array, then apply tonal corrections and spot dust. One bizarre side-effect of XMP is that if I take a 16-bit TIFF straight from the slide scanner, then apply curves and reduce it to 8 bits, somewhere in the XMP metadata that Photoshop “helpfully” embedded in the TIFF the bit depth is not updated and Bridge incorrectly shows the file as being 16-bit. The only way to find out is to open it (Photoshop will show the correct bit depth in the title bar) or look at the file size.

This bug is incredibly annoying, and the only work-around I have found so far is to run ImageMagick‘s convert utility with the -strip option to remove the offending XMP metadata. I did not pay the princely price for the full version of Photoshop to be required to use open-source software as a stop-gap in my workflow.

Photoshop will embed XMP metadata and other cruft in JPEG files if you use the “Save As…” command. In Photoshop 7, all that extra baggage actually triggered a bug in IE that would break its ability to display images. You have to use the “Save for Web…” command (actually a part of ImageReady) to save files in a usable form. Another example of poor fit-and-finish in Adobe’s software: “Save for Web” will not automatically convert images in AdobeRGB or other color profiles to the Web’s implied sRGB, so if you forget to do that as a previous step, the colors in the resulting image will be off.

“Save for Web” will also strip EXIF tags that are unnecessary baggage for web graphics (and can actually be a privacy threat). While researching the Fotonotes image annotation scheme, I opened one of my “Save for Web” JPEGs under a hex editor, and I was surprised to see literal strings like “Ducky” and “Adobe” (apparently the ImageReady developers have an obsession with rubber duckies). Photoshop is clearly still embedding some useless metadata in these files, even though it is not supposed to. The overhead corresponds to about 1-2%, which in most cases doesn’t require more disk space because files use entire disk blocks, whether they are fully filled or not, but this will lead to increased network bandwidth utilization because packets (which do not have the block size constraints of disks) will have to be bigger than necessary.

I wrote jpegstrip.c, a short C program to strip out Photoshop’s unnecessary tags, and other optional JPEG “markers” from JPEG files, like the optional “restart” markers that allow a JPEG decoder to recover if the data was corrupted — it’s not really a file format’s job to mitigate corruption, more TCP’s or the filesystem’s. The Independent JPEG Group’s jpegtran -copy none actually increased the size of the test file I gave it, so it wasn’t going to cut it. jpegstrip is crude and probably breaks in a number of situations (it is the result of a couple of hours’ hacking and reading the bare minimum of the JPEG specification required to get it working). The user interface is also pretty crude: it takes an input file over standard input, spits out the stripped JPEG over standard output and diagnostics on standard error (configurable at compile time).

Update (2006-04-24):

Reader “Kam” reports jhead offers JPEG stripping with the -purejpg option, and much much more. Jhead offers an option to strip mostly useless preview thumbnails, but it does not strip out restart markers.
