monday mixdown: teeth, dtv follies, and why bikes are cool

Here’s what’s been on my mind over the past week:

Had a root canal last Tuesday. It was amazingly low-pain and low-stress, all things being equal. The only thing is that I need to chew on one side of my mouth, as the rooted tooth only has a temporary crown on it right now. My appointment for filling and fitting of the permanent crown isn’t until February 3rd, unless there’s a cancellation and the doctor can work me in earlier. Until then, well, it’s a lot of careful, mindful chewing.

So are there any other folks having a tough time getting digital TV reception in their apartments – especially those living in basements or other locations with challenging exposure? It seems that the DTV standard, as ratified and endorsed by the FCC, doesn’t account for folks who can’t place a high-exposure outdoor antenna to draw in signal. Sure, they have suggestions for folks who only have indoor antennae (e.g. folks who rent), but the ultimate suggestion is to get an outdoor antenna.

So even though I’ve bought a DTV converter box and use an amplified antenna, I still get a fraction of the channels that are available on the still-extant analog transmission lines. Under the old (and still useful, at least until February 17th) analog system, we receive NBC, Fox, ABC, CBS, CW, MyTV, MHz, ION, Telemundo and three PBS stations – 12 stations in total. With our DTV converter and the antenna placed near our window (as suggested by many sources), we get NBC (with its two digital sub-stations), Fox (sans sub-station), CBS (with its weather sub-station), and Telemundo (sans sub-stations).

No ABC. No PBS. No CW, MyTV, ION or MHz.

And folks keep suggesting that I get cable to fix things. But I’m loathe to spend $15 per month ($180 per annum) on something I currently get for free. And while Hulu is a reasonable substitute for now, my guess is that The Powers That Be will begin charging users to view current programming.

Furthermore, there’s the “cliff effect,” where a digital signal goes from full clarity to zero signal very quickly. this is a marked difference from analog, where static may cause the picture to get fuzzy but still provides a watchable program stream. Not so with the digital replacement: it’s an all-or-nothing venture. And in an area where there are many interference variables, watching can be very frustrating. For example, there is a lot of low-flying helicopter traffic in northwest DC (thanks to the presence of government agencies, the VP’s residence, the White House, embassies, and three hospitals), and each time one of these silver birds flies overhead, the digital signal freaks out and drops.

So this isn’t really an improvement in quality, is it? Methinks that somebody will go class-action on this, and I hope it happens – this “new, improved TV” is anything but. Something fishy is afoot, and I think that the telecoms, cable providers and TV manufacturers were at the wheel of this change: looking for money at the expense of serving the public.

For shame, for shame.

Now back to better things:

I spent Sunday mid-day on a wonderful dirt road ride with Darren out in Loudoun County. Of the almost 35 miles we traversed, climbed and descended, only a handful were on paved roads. The dirt was damp and occasionally glue-like, but offered great traction. Also, it was a lot of fun to take out my old mountain bike on the kind of surface for which is was designed. Sure, Darren had a decided advantage with his cross bike (as well as the fact that he rides off-road far more often than I), but it was great fun on an otherwise mellow weekend.

The best part is that riding the dirt roads of Loudoun County provides a unique view of a very scenic part of Virginia. Sure, you could drive these roads, but the view wouldn’t be nearly as good or all-encompassing.

- – – – -

And another great thing about bikes? They’re one of the only vehicles that will be allowed across the Potomac bridges on Inauguration Day. So to all my Virginia-based readers (all, what, two of you?) who want to commute into the District and not take Metro: dust off those bikes and ride in! Plus, riding in will keep you warm with the workout (it’s forecast to be bitterly cold – or at least seasonably chilly – on the big day).

I hope this is just the beginning of the end of stupid, single-occupant car commuting from Northern Virginia (as well as nearby Maryland) into the District. We have plenty of easy ways into the city that don’t involve increasing traffic volume, spewing pollutants into the air, and otherwise driving locals nuts when you take all the zoned parking for hours at a spell: try Metro, try a bus, ride in on a bike, walk, or do a mix of these. It’s not difficult, and it’s better for all of us.

using wordpress? be careful with free themes

Folks who follow this blog know that the look has changed over the past week.

Part of the reason why this happened is because I wanted to change things up. I upgraded to WordPress 2.5 – no probs there. And I looked for a different theme to mark the change.

So I looked for a freebie to act as a stop-gap and found a theme that was GNU-licensed and open-source, which would allow me the flexibility to change things up. I found one at a free WP theme meta-site, which seemed fine, and I installed the theme.

Then I got around to looking at the PHP code to see where I could tweak things, and I noticed some strange, base-64 encoded strings in some of the files.

Commence mental alarm bells.

So I look at some of the WP developer blogs (those referenced in the default RSS feed on the WP admin page of almost every WordPress-driven site) and found this post from an open-source theme developer. It seems that some of his themes had been swallowed up by a free theme meta-site and doctored with this base-64 code. This developer did some snooping and asking around, and found that the inserted code was definitely not WP standard, and was very likely malicious:

I think the potential for abuse of this script is huge. I see it as a covert channel to setup Word Press enabled sites as thin zombies. The code being sent back to the server and eval’d could be a mailing script for spam or phishing.

So I decided to reverse-engineer the whole damn thing, stripping out all malicious code, and seeing how it turned out. It’s not bad – looks and acts the same, without all the scary eval calls and potential for hacks to my site.

So to anybody developing for WordPress (or Joomla, which is equally vulnerable to these exploits), the safe bet is to use the WordPress theme directory from WordPress.org.

Caveat emptor means more and more in the days of the internet.

gizmos for the bike

As I get ready to post a review of a cool, bike-oriented gadget, I point to this wonderful, does-it-all computer for the bike: the Cerevellum Bike Computer.

Sure, it costs as much as a laptop, but it has features: the usual speed, distance and time, as well as a GPS, elevation gain/loss, wattage produced, and rear-view video.

Yep: a USB-based rear-view camera is one of its possible accessories.

Note that the thing is still a prototype, and there are still other questions to be answered (namely battery life). But it’d raise Garmin’s game a notch, right?

a quick bike thought

It’s cool to see tech that was developed when you were first in college enter into the world of bicycle design. Too cool.

(Hat tip to Adam.)

tuesday quick quips

Some things that have crossed my mind today:

  • WAMU’s decision to relegate their bluegrass programming to the HD range is flat-out stupid. The powers-that-be at WAMU continue to prove that they know how to implode a local radio station, creating more of the same (political talk radio and over-syndicated NPR content) rather than provide a format that’s unique. If anybody from the “home of Kojo” is reading this: take a long, hard look at WFUV, KRCL or WXPN to see how independent public radio is done. Seriously: we don’t need rehash of stuff that every other NPR affiliate is doing.
  • The first public beta release of Eudora’s new mail client, code named “Penelope”, is a major letdown. Let me summarize: it’s essentially Thunderbird with Eudora’s icons and sounds. If I were a Eudora user, I’d be miffed that we’ve waited all this time for a version of Thunderbird with new curtains. Where are the features of the old program that made it a standout? Are they in some internal build that will see the light of day in 2012? Disappointing, Mr. Dorner and open-source dev crowd – simply disappointing.
  • It was refreshing to hear a Republican consultant on this past Sunday’s Meet The Press admit that Fox News is the official media outlet for the GOP. Finally: a theocon who says something that isn’t mealy-mouthed and half (if that) true!
  • I’m still not sold on any of the current crop of presidential candidates. However, there are some who continue to inch their way down in favor, including Bill Richardson (miffing the question on whether being gay is a choice or genetic, and doing an “I don’t know” on the $50 billion Iraq funding bill).

Now, off to a ball game….

bling

Campagnolo Centaur rear derailleurThe latest part arrived for the new bike today: a Campagnolo Centaur rear derailleur, 2007 model.

Dig the carbon fiber outer plate – high bling factor there, plus a (somewhat trivial) weight saving over an all-metal unit.

And it should match well with the other parts in the works – especially the carbon fiber Chorus brake/shift levers.

If my patience can last until October, that’ll be something.

free at last – and it was a good ride

As of tonight, I’m no longer on the executive board of DC for Democracy.

The elections came and went. There was only one contested race – for chair – and the vote went in a predictable direction. Many of those who felt left out of the organization after the big schism surrounding the 2005 United For Peace/International ANSWER D.C. Anti-War Mobilization turned up. Looking at the crowd assembled at Ben’s Chili Bowl tonight, I saw a lot of faces who haven’t been active in DC4D since that voting night.

There were some nasty personal attacks delivered during the candidate speeches that were totally uncalled for. But they didn’t really matter to the crowd of “long-lost” members, who were there to see one of their own ascend to chair.

And I wish them well.

But it remains to be seen what my level of involvement will be.

Hopefully, DC for Democracy will continue to be a welcoming organization to people across the liberal and progressive political spectrum. The organization has typically taken many viewpoints into account when making decisions about policy and efforts. While this can alienate the more zealous and activist members, it also provided a breadth of opinions and input to the organization that allowed it to be involved in many disparate activities without losing group cohesion.

The new leadership is certainly more activist and blatantly progressive in its makeup, which can be good if dissenting opinions are taken into account with policy and activity decisions. I have my doubts about whether this will happen (some words said by the winning candidate attacked her predecessors and opponents in a passive-aggressive manner that was completely unwarranted), but I’m going to give the new leadership the benefit of the doubt for a little while.

But deep down, I worry that this swing of the political pendulum within the organization will create a flip-side schism between the driven activist crowd and the old guard. I hold DC for Democracy close to my heart – after all, I was there for its founding, helped draft its by-laws, and have seen it though triumphant highs and depressing lows. And I want to remain involved as a rank-and-file member, but not if it means compromising my own principles.

And it’s not like I don’t have other things on my plate that could use a bit more attention if I find that DC4D is no longer an organization with which I can identify.

So, like I said: we’ll see.

Going back to my former executive board involvement: the reins to the org’s website have been passed to a new steward. I wish him only the best in keeping things fresh and well-tended. One thing I do know is that the website is in capable hands.

So thank you, DC for Democracy. It’s been a helluva ride.

on wikipedia politics

I love the politics of Wikipedia, especially when the “size of your manhood” debate rears its ugly, pointless head.

Case in point: the current uproar over the entry for Annabel Port, one of the co-hosts of “The Geoff Show” on Virgin Radio. Somebody suggested that Ms. Port’s entry be deleted as she is “of insignificant merit.”

There is a link for discussion of this issue, and many people – myself included – have chimed in with our opinions. Yet there’s a user who is trawling this discussion and trying to discredit those who haven’t made umpteen contributions to Wikipedia entries.

I’ve contributed to Wikipedia a total of 31 times. Most of these are edits to correct grammatical errors or add minor data. But in doing so, it’s increased the quality of these entries, making them more legible and accurate. I don’t contribute to entries where I have little-to-no knowledge of the subject matter at hand. You can view my contributions by clicking on this link.

Yet a Wikipedia user who thinks very highly of himself is harping on me for “only contributing minor edits to articles” as a means to somehow discredit my opinion on an entirely subjective matter.

Repeat after me: what the fuck?!?

If you check out my edits, many are, in fact, minor. But they’re edits that have stood the test of time. And some are major additions or necessary re-formatting of pages to make them more useful to Wikipedia patrons. The fact that most of my entries have survived intact should be a sign that my work hasn’t been trivial.

A look at MSJapan’s contribution history shows that he’s performed more edits and engaged in more discussion, but that his contributions haven’t necessarily been any more major than mine, or those of other Wikipedia users who he’s chosen to try and discredit.

So, to MSJapan, I say this: get a first life!

(Update: the eventual outcome of the Annabel Port entry was to keep it – yay, Annabel!)

upgraded to worpdress 2.1 “ella”

Late last night, WordPress 2.1 “Ella” (named after Ella Fitzgerald) was released into the wild.

Of course, I had to try it out!

I first upgraded Off The Eaten Path to the new WP engine, and the upgrade went through without a hitch. The one catch: OtEP is a very simple blog, with very few modifications or plug-ins.

So I approached the upgrade of randomduck with a bit more caution, as WP 2.1 does quite a bit of back-end tweaking to the system. The basic rule-of-thumb: once you’ve run the upgrade, you can’t roll back to version 2.0.7.

Eep.

But I carried on, making sure that I backed up everything before running the upgrade.

And?

Needless to say, it worked – after all, I’m writing this post in the WP 2.1 composition window (which auto-saves posts – so, so handy).

So hats off to the WP dev and testing team – they did a great job!

finally: photoshop for intel macs!

Adobe Labs delivered an early Christmas present to all Mac users who use Intel-based Macs: a beta release of Photoshop CS3. This new version is a universal binary, so it runs natively on both PowerPC and Intel Core systems, but the beauty is that I can finally run Photoshop at a decent clip on my Mac mini.

So far, the testing has revealed a very capable product. Launch times are quick, and all the tools run very, very quickly. Before I installed the CS3 beta, I was purposely running an older version of Photoshop – version 7.0.1 – to minimize any slowdown from Rosetta emulation. And while that was fine, I missed out on many of the improvements that make Photoshop CS2 such a great application. So now I have all of the cool tools without the speed penalty – what’s not to like?

Well, is there’s one gripe it’s this: the CS3 beta takes up a great deal of hard disk space, so it’s likely that I’ll need to install a new hard drive in the mini sometime in the not-too-distant future. Granted, I installed every available bell and whistle, so I could’ve whittled down the disk load a bit.

And this is a beta application, so there are bound to be a few spanners in the works. So I’m keeping Photoshop 7 installed on my mini, just in case, although I haven’t read about any major deal-breaker problems with this beta.

I’ll keep folks posted as my testing continues.
