We went to the county fairgrounds last night to see the July 4th fireworks...

The fairgrounds are across the road from my high school, home of the State Champion Skyhawks!!


I took a couple of photos before the sun went down...

Once it got dark it was fireworks time. For a small, local fireworks show it was pretty good.

This was my first time trying to shoot fireworks – I got some hints from this site – but I think I did a pretty good job.

I used my tripod and remote shutter release. The camera was on bulb mode so I could manually control the shutter. I used my prime 28mm lens at ƒ/16 and focus at infinity. I just used the first couple of bursts to get the framing right and locked down the tripod and shot in 1-2 second exposures.

It was a little tricky to get the timing right. The best shots were those where I opened the shutter right before the firework exploded and closed just before it reached it's largest size in the sky. On a lot of them I just got lucky, of course.

I also should say that the fireworks photos below are almost completely untouched. The only corrections are the lens profile fix – fixes the distortion in the wide angle lens – and a little bit of sharpening. I haven't messed with exposure, color, or even cropping.

Next time I think I'll try shooting vertical to get more of the sky in frame and either move further back or invest in that Sigma 20mm wide angle I have my eye on...

Here are the good fireworks shots in a gallery:

Update: If you would like to see the high res versions of all of these fireworks photos my flickr album is here.

WWDC News for Normals

Yesterday Tim Cook gave1 the keynote presentation for the 2014 Apple Worldwide Developers Conference. I’m not a developer, and 99.9% of the readers of this site aren’t either so here’s the stuff that’s important for us ‘normals’.

OS X Yosemite

The newest OS will be called Yosemite – you know, a place in California that people other than surfers have heard of – and it will be released this Fall for free. You can sign up for the open beta program and put it on your Mac before then but, as I said on the podcast it’s probably not a good idea to put an OS beta on any machine you need to rely on.

A lot of UI elements – icons, buttons, menu bars, etc. – have been redesigned to look more modern and more like what we have gotten used to with iOS. And these designs seem to be getting much better reactions than the first designs of iOS 7. They’re not very jarring and seem intuitively functional.

Spotlight, which I’ll bet very few people actually use, is getting an upgrade to make it more like quick-launch apps like Alfred and Quicksilver. From Wired’s WWDC Keynote summary:

With Spotlight, you can now tap the magnifying glass to pull up a larger search bar in the center of the screen. From there you can search and open apps, pull up reminders and calendar events, or search information on Wikipedia or the web. Maps is also accessible from Spotlight—you can search for sushi, get map information, results from Yelp, and more. If you search for a movie, it gives you movie location and ticket information when applicable, as well as information about availability in the iTunes Store.

I don’t know if many more people will use it but it does show that Apple, much as they did with Sherlock, pays attention to how third-party developers provide OS-like tweaks and, right-or-wrong, incorporates those features into the official OS.

The best news for OS X, in my opinion is built-in support for DuckDuckGo in Safari search. Now you can use a search engine that doesn’t track you (ahem, Google) as the default search in Safari without jumping through hoops. Safari itself is getting some under-the-hood improvements, too, that will be transparent to most users.

iOS 8

There are lots of cool improvements coming this fall with iOS 8. Like Yosemite it is going to be free. If recent history is any indication it will come out right around the same time Apple debuts new iPhones.

I am really excited about actionable, interactive notifications. No longer will swiping on an alert just take you to the alerting app. You can actually respond to a text, like a Facebook post you’re tagged in, and, though they didn’t show it on stage, hopefully favorite or reply to Twitter mentions.

Mail on iPhone and iPad is getting some good updates. Swiping on messages to flag, mark unread, etc., is a nice improvement that third-party apps have had for some time. And the ability to minimize a draft email to look at other messages is going to be very useful, especially since message threading doesn’t always work the way we would like it to.

The iOS keyboard is getting a predictive text feature called Quicktype. And it’s very smart. Also from Wired:

Heavy typers will also enjoy iOS 8. A new keyboard feature called Quicktype, which supports predictive typing selections, lets you type “faster than ever before.” If someone asks you, “Do you want to go for dinner or a movie?” Your reply gives you options to select automatically, including “dinner” and “a movie,” so you can reply in a snap. This is great—Android and Windows Phone have been far more advanced in this respect than iOS. Apple also says that your typing is kept private—none of your keystrokes leave the device.

By far the iOS feature set I’m most looking foward to is the improvements to Messages. Now you can name message threads (no longer are they just titled with a list of who is in the conversation) and participants can be added and removed from threads. And if you’re in a thread that you don’t necessarily want to get out of but you don’t want constant notifications for you can mark it “Do Not Disturb”. Messages also supports quick audio and video messages and received audio/photo/video data will “autodestruct” after a while (unless you save them) so they don’t take up space on your device.

The iOS photos app is getting enhanced search so you can find that certain photo you took last year more quickly. And the editing is getting enhanced with easier to use lighting and color adjustments. Edits will be persistent across all of your Apple devices but they are also non-destructive. Apple didn’t make photo storage free as some thought they should, but they’ve updated the pricing to be very affordable. Up to 5GB iCloud is still free. For 20GB you will pay just $1 a month and to go up to 200GB is just $3.99 a month. So, just take all the photos you want and don’t worry about dropping $12 a year to do it.

Other Stuff

Apple announced Extensions. This is a way for applications to share data and services. The most important part of this for most people is that apps will be able to have a presence in the sharing menu and in Notification Center as widgets.

HomeKit, HealthKit, CloudKit, Metal, Swift. Right now these are mostly for developers so they can start making apps that take advantage of these new technologies, but it won’t be long before you see more apps for automating your home, tracking your health status, and other apps and games that use these protocols.

Bottom Line

OS X Yosemite and iOS 8 will be out, for free, this Fall. Get them then. Don’t try to put beta software on any device you need to rely on. And the new developer technologies and tools that were announced this week will start being implemented in third-party apps soon, as well.

Irr Con Pod Logos

We have a brand, spanking new logo for Irrational Confidence! I thought it might be interesting to take a look back at the logos we've used for the podcast.

I actually can't find a copy of our first logo, but it's not really worth showing anyway. It was just the name on a solid background... I think.

Here is the first real logo we did, us and puppies! This might look like a photo shoot from Breaking Bad with our heads on Bryan Cranston's and Aaron Paul's bodies, but nope. It's us and puppies.

This one was a blast. Man we loved that scooter.


And here is our latest logo. As we stated on the latest episode this is a photo from our early days and not at all a photo of Eddie Vedder and Jeff Ament with our heads photoshopped on. Those were good days back then.


I missed Beatrix's first two soccer games because they were postponed (thanks, climate change) due to stupid weather.

But Erin was there with my camera to document her first game...

This weekend I was off of work and got to go see her Saturday morning game. And it was AWESOME.

She played hard, had a great time, and even scored three (3!) goals. Here are some pics from the game:

I didn't get any video or photos of Beatrix's first ever soccer goal – I was much too busy yelling – but here's a decent vid of her kicking in, playing defense and assisting Jillian with one of her goals.

And here you can see that I stopped cheering just long enough to take a pretty crap photo of Beatrix's third goal during the game:

On Digital Audio and Wasting Money

Maybe I just don’t get it.

I have a pretty decent “Hi-Fi” system. All of my digital music is on my Mac, upgraded to the highest quality with iTunes Match1. The fanciest part of my system is a DAC – the Meridian Explorer – that sits between the Mac and my amplifier. It’s just a nicer, external sound card that decodes the digital files and outputs analog audio.

From there I have a pretty inexpensive receiver, the Onkyo TX–8255 that powers my old, but still decent Sony speakers. I think the speakers came with a home theater system I got about fifteen years ago. They still sound great.

I have two sets of headphones. A pair of decent closed ones, the Sennheiser HD 380 Pro headphones that I got last year on Black Friday for almost half-off. And a set of Grado SR80i’s. The 380’s are higher audio quality and more accurate. I hear everything in them. I have the recording of Ralph Kirshbaum playing Bach’s Cello Suites and you can hear him breathing on stage through the 380’s. The Grado’s aren’t quite as accurate as that but they have a warm, rich sound that I really like. And they were my first high end phones so there is some sentimental value there, too. I end up using the 380’s more often. They also get used for recording the podcast because they don’t bleed audio into my mic.

So, from iTunes to the sound output of the Explorer everything is digital. After that I have low- to mid-range audio gear getting sound in my ear holes. I’m sure purist audiophiles would find a great deal to dislike in this system, but to me it all sounds amazing. Really.

That’s why I think maybe I just don’t get it. Because there is a Kickstarter project for a new audio player that’s supposedly going to let you listen to music the way the musicians intended. You see, all of the music I have is ruined because it’s in a digital format. My music has been sampled and digitized and, apparently, adulterated to the point that the difference between what the musician played and what I hear is dramatic.

This audio player, Pono, has the self-proclaimed mission “to provide the best possible listening experience of your favorite music.” It’s being headed up by aging rocker Neil Young. It claims to bring you music much closer to what the artist intended than an mp3. Young, in the Kickstarter video even compares mp3 files to listening to music underwater. And, from an interview with MTV News (quoted here) he said:

“I’m finding that I have a little bit of trouble with the quality of the sound of music today,” Young said. “I don’t like it. It just makes me angry. Not the quality of the music, but we’re in the 21st century and we have the worst sound that we’ve ever had. It’s worse than a 78 [rpm record]. Where are our geniuses? What happened?” Young argued that MP3s feature only 5 percent of the data from an original master file, which he sees as a major problem.

Ok. Time for some reality2.

Neil Young. I love his music. I’ve heard he’s a great guy. But the man is approaching seventy years old and he has been abusing his ears with ridicuously loud live rock music since he was sixteen. He may hear a difference between the mp3 files he derides and his magical 192kHz files but the reality is that he isn’t a very good judge of sound quality and he isn’t comparing apples to apples.

Sampling rates3. Young and Pono are proclaiming that 192 is a magic number that’s closest to the analog music that the artists intended – let’s ignore for now that the vast majority of musicians today record digitally. Ok. Great. Do the dupes backers watching the Kickstarter video know what that number even means? In case you don’t, 192kHz refers to how many times per second the audio was sampled while being digitized. In this case 192,000,000 times. That is a lot of samples per second. And it sure does seem like 192 is better than the 44.1 that CD’s have.

All things being equal, sure, higher sampling rates mean more of the original information is “preserved” in the digital file. But there are a couple of realities here that might not be obvious.

First, there is a pretty good reason the people engineering the compact disc in the 1980’s chose 44.1kHz. The upper limit of human hearing is roughly 20kHz. Sound waves with a higher frequency than that just don’t register in your ears unless you’re a labrador. Most people can’t hear anywhere near that well. And our hearing degrades as we age. The ringtone for teens that adults can’t hear that was popular a few years ago4 was only 17kHz and I couldn’t even hear it then. So, when they were figuring out how to digitize music for compact disc the engineers took the upper limit of human hearing, doubled it, and added some more head room. There is actually some evidence that the ultra high sampling rates can cause audible overtones that actually make the final audio sound worse.

Secondly, there is the act of sampling itself - encoding and decoding the files. I don’t fully grok all of the math for it not being an audio engineer or a physicist but my understanding is that the way the sampling works there is virtually no audible information lost in digitizing audio files. Please take the time to watch this surprisingly fascinating video for a really good demonstration of what’s going on with sampling at different frequencies and bitrates. And for getting clean files without noise there is no contest. Digital beats analog hands down.

There is another pesky reality about sampling frequency that doesn’t get mentioned. Quality of the source material. I’m not saying that all the old music we listen to suffers from poor recording but surely a lot of it wasn’t recorded under ideal circumstances. Not every band had access to Abbey Road or Sound City. If the source material wasn’t recorded perfectly, or mastered well, or the analog recordings have deteriorated before being digitized it doesn’t matter how many times per second it’s sampled. Crap in, crap out.

This has all been a long, rant-y, way to say one thing. Sure, you can spend $400 on a music player for super-high-quality music files that are as good as digital music can get. And you can pay a lot of money to upgrade your library of music because none of your music is sampled at that rate. And you can fill up your hard drive with it because those files are enormous compared to the mp3 and AAC files you have now. You can do all of that.

You can also buy a $10,000 headphone amp, a set of $4,450 headphones and grab some $21,000 cables.

But will you notice any difference at all?

Reality and cold physics say no, probably not.

  1. It's pretty easy to do, actually. Complete instructions here.

  2. Backed up by, you know, physics.

  3. I am not even going to get into bit rate. I'm no audio engineer.

  4. I have no idea if it's still used, obvs.


Beatrix was getting pretty bored with her at-school soccer program. I don't think they did much more than kick a ball around the gym. So, we signed her up for Chesterfield United's U-5 rec league soccer.

This is, of course, her first time on a "real" soccer team. But at her first practice this week she jumped right in and was running and kicking with the best of them.

Sure, there are only five kids on her team and they only practice for an hour a week but she's got cleats and a jersey and everything so it's the real deal.

I took a ton of photos at practice but I was able to narrow it down to twelve good ones and I'll put them in a gallery so I don't completely fill the front page of the website with them...

Airplanes and Spaceships

This past Tuesday I was off from work and took the opportunity to take Beatrix to the Steven F. Udvar-Hazy Center in Chantilly, VA. It’s part of the Smithsonian Air and Space Museum but it’s out at Dulles instead of being in DC proper. Admission is free just like the other Smithsonian museums but you do have to pay $15 to park there (ouch).

The museum has air- and spacecraft from the earliest days of aviation right up to the present day. Some interesting things there that I stupidly didn’t get photos of: a Concorde, a helicopter that was flown around the world, the Enola Gay.

But I did get photos of some things…


The Corsair from World War II is one of the first things you see as you enter the museum. They have aircraft on the floor and hanging in mid-air and some even placed under the wings of larger planes. The place is just full of planes.


I had never seen a SR–71 Blackbird in person. It’s a big plane but somehow smaller than I imagined. This is the view from the entrance area down to the floor of the main hangar. You can just see the Discovery in the space hangar in the background.


Beatrix with the enormous engine from a Boeing 777. She’s about 20–25 feet in front of it. It is a lot bigger than it appears in this photo. And she was having a much better time than she appears to be having in this photo.


One of the neat things about the place is that having things on multiple levels lets you see each aircraft from several perspectives. Interestingly the Blackbird is one of the only planes that doesn’t have the number manufactured on the info plaque. Still classified?


Do some of that pilot shit, Mav! I had to get so far away from the F–14 to get it in frame that I was almost to the opposite wall of the hangar.


They don’t have a huge number of helecopters but the ones they do have are pretty significant. It doesn’t get much more iconic than the Huey.


Heading into the space hangar Beatrix was interested to see the Mercury capsule since she had gotten in the replica at the science museum. This one was scheduled to go into space but didn’t make it before the Mercury program was stopped and Gemini began.


As with the Blackbird, I had never seen a space shuttle in person. It is much, much bigger than I had imagined. The bottom of the nosecone is just about my height. And they purposefully left it looking as if it had just re-entered the atmosphere with scorched tiles and everything. For me seeing Discovery was by far the most interesting part of the trip.


Another look at Discovery. For perspective the guy in front of the shuttle is just a smidge shorter than me. And hanging directly above the shuttle is a TDRS – Tracking and Data Relay Satellite – which is interesting because NASA just launched the latest one, the TDRS-L last month.

We will definitely go back to the Udvar-Hazy Center again. We had a great time walking through aviation history. I would like to go sometime when I can take my time and really explore everything in detail.
