With the release of Aperture 3, geotagging photos is now an integral part of the application’s workflow. Aperture grew the Faces & Places features like iPhotos!

In particular, the Places feature allows you to import GPS data from iPhone photos or from GPS data captured by pretty much any device that can spew a standard GPX format data file.

Tagging from the iPhone is straightforward. With the iPhone connected to your computer, go to Places in Aperture and then select Import from iPhone Photos…. Aperture will then display all the photos on your iPhone that have GPS metadata and you can pick the photos from which the GPS data is to be imported. Once picked, Aperture will apply the GPS data to photos taken near the same time as the imported data.

However, one issue with the iPhone is that it really isn’t a terribly good GPS logging device. Using it as one eats the battery and the data generated often has holes. And, because the iPhone uses A-GPS (GPS assisted by cellular signal), it doesn’t work at all when hiking in areas without cell signal. Apparently, I’m mistaken about A-GPS — it should fall back to regular GPS behavior. My experience, though, is that the iPhone just isn’t a terribly good GPS device when it doesn’t have a cell signal and has often been off by miles when in the hinterlands. It works great when on the road or near cities, though.

My red stapler — like the one pictured at left — has broken due to the classic industrial design mistake of using a plastic part as the connector between two mechanical parts in a leverage or geared based mechanical system.

Swingline has a customer feedback form and, thus, I sent the below feedback. We shall see if anything comes of it.

Hi!

I could make a classic Office Space style joke about my Red Stapler and Burning Down the building, but I won’t. I’m sure you’ve heard ‘em all before.

I have a classic red Swingline stapler. It is a work of art.

Unfortunately, it suffers from a classic industrial design mistake. The red metal halves are held together by a plastic clip. Said plastic clip broke and what should be a single mechanical unit is now two dysfunctional, yet attractive, pieces of red metal.

As much as I would like a replacement part (it is the u-shaped bit that holds the stapler halves together), I’m far more interested in seeing Swingline fix the faulty design.

Thank you,
b.bum

Human blood cells

Roger has always excelled in math and sciences — no surprise given lineage — and is of the age (9) where the science education is moving into bigger and smaller areas of study.

So far, he has gotten by with a QX-5 Digital Microscope
and mixScope. While the QX-5 is great for looking at money, the veins in leaves, bits of mushroom and tiny critters, high magnification is pretty much useless because the construction makes focus impossible.

Thus, the desire to get something more like a real microscope. In particular, I really wanted a microscope that allows for live viewing on a computer screen (like the QX-5). While, there were some good ones for less than $500 — 3MP digital camera model microscopes that included simultaneous use binocular eyepieces, even — their software is pile of Windows only crapware.

No, thank you. Next!

Close-up of cross section of spinal column.

Enter the Celestron 44340 LCD Digital LDM Biological Microscope. It replaces the normal eyepiece with a 2.1MP digital camera and a color LCD screen. More importantly, the build quality is actually quite decent such that focusing at, even, the 400x maximum optical zoom is quite smooth!

Unlike the QX-5, the Celestron 44340 is really only for use with proper microscope slides (The QX-5 still has a purpose!). blank microscope slides and slide covers are cheap, so I picked up a bunch of those, too.

The slide table includes a very nice set of caliper style adjusters for moving the slide around in a highly controlled fashion. Slides are held in place by an easy to use spring loaded caliper.

The microscope can illuminate the subject from either the top or bottom and the bottom illumination includes a variety of color filters that can be quite useful. Intensity of illumination can be adjusted.

The top illumination is nearly useless at all but the lowest magnification (otherwise there isn’t enough distance between lens and subject).

The digital controls include an EV adjustment, a digital zoom, and the ability to take snapshots. Digital zoom only works when the snapshot resolution is configured for less than 1600×1200. Digital zoom works by interpolating data across the sensor into a lower-than-sensor resolution image that provides a higher-than-optical zoom factor. It actually works fairly well (unlike most digital zooms).

Pollen. Evil, evil, pollen.

The unit also comes with a really nice hard sided carrying case, a dust cover, and power adaptors for global use. A surprisingly complete kit — I was completely blown away by the quality of the case for a device this relatively inexpensive.

My only real complaint is that the LCD is effectively physically attached to the camera & lenses. That, combined with the relative stiffness of the buttons means it is hard to take an image that isn’t blurry. However, it seems that the unit has a slight delay between button push and recording such that is isn’t as big of a problem as it could be. But, still… stupid design — just move the damned shutter button to the base. I’ll probably hack the unit to add an external shutter button.

All in all, I’m thoroughly impressed by the build quality and feature set of this microscope. I would still have been impressed if my $180 had purchased a microscope with this optical performance, sans awesome case and really nice slide table.

All of the images in this blog post were taken with the microscope, no surprise. It is a boxed set of prepared slides that I also picked up from Amazon.

We have a ton of Christmas music — 400 or so tracks, with it growing by about 50-75 tracks each year — that ranges across all genres. It is some awesome stuff; blues, reggae, pop, traditional, you name it…

However, it is music that should only be in the rotation starting December 1st, heavy rotation by about the 15th-20th and then no more from December 26th to the next December 1st.

Of course, iTunes is agnostic and, thus, does not follow my holiday music filtration wishes.

Easy to fix.

1. On all Christmas/Holiday music, add a grouping of “Holiday” or “Christmas” (or whatever you want).
2. Create a smart playlist that finds all music in said grouping. Make sure the smart playlist matches unchecked items.
3. On December 26th, select all, ctrl-click, and select uncheck selection
4. On Decmber 1st of the next year, select the smart playlist, select all, ctrl-clik, and select check selection

Done. iTunes will not select unchecked songs when constructing genius playlists or when playing through the library on shuffle play. Smart playlists can optionally include checked songs.

I have long wanted a really good toaster oven. One that had decent capacity, was versatile, and insulated such that it doesn’t lose a ton of heat when sticking food into it. As well, I can’t deal with poorly designed products and will often choose dead simple over a full featured item simply because simple is harder to screw up.

After 8 months of research and comparisons, I finally settled on the Breville BOV800XL Smart Oven. It isn’t simple and it certainly isn’t cheap, but the Breville is really quite an excellent piece of technology.

The Breville’s controls are straightforward. You select the mode first, then there are two additional dials that configure, effectively, temperature and time. For toasting, the two additional buttons select slices and darkness; seemingly silly, but it actually works quite well!

As well, the toaster oven has a convection setting and a “frozen” setting that automatically adjusts the cooking times to account for cooking frozen foods. The “frozen” button is the one feature that borders on frivolous gadgetry. Then again, cooking random frozen foods really isn’t a part of our diet. If it was, the adjustment it makes actually does make sense.

The interior capacity is large enough to bake a 13″ pizza or roast a whole chicken (though you might have to cut it into two halves). Combining decent insulation with high wattage, the Breville both heats relatively quickly, holds heat well, and the outside does get warm, but not terribly hot.

When the internal rack is in toasting position, opening the door magnetically slides the rack out a few inches. Very convenient.

All in all, the Breville is a well engineered kitchen tool. It can easily replace your toaster and can often fill in for your full sized oven while both pre-heating more quickly and using less electricity overall. And, of course, the Breville can act as a secondary oven for those times when you need two ovens.

Since the addition of the Breville to our cooking toolset, it sees daily use.

Ow ow ow ow.

Do not buy this fan.

It can shock you.

Specifically, the metal toggle switch’s handle is spring loaded such that if you push on it like a push button, it will short out internally. Not only does it send a pretty spray of sparks out of the switch, it will also shock the crap out of you.

As suggested, I have reported the fan to the Consumer Product Safety Comission and will write-up whatever the followup experience may be.

I’m the first to embrace that much of this was written in anger and, though I might now word it differently, I’m not going to because it captures the depth of frustration and crappy experience I endured (a first world problem, assuredly).

But, hey, let’s make the vitriol useful– if there were a means that I could report bugs, I would. If there were a way to capture the state of my machine for validation, I’d do it. If there is some way that my crap user experience could be used to prevent future user abuse, that’d be awesome.


To be completely blunt: The team responsible for the PS3 non-gaming user experience — the menus, data management, user interface, and everything else that doesn’t happen in game — are either incompetent buffoons or have a management chain and/or product marketing/design/definition demands that are ridiculous, stupid, and an insult to the customer. (Personally, I’m betting it is the latter — the PS3 is an impressive piece of engineering, both software and hardware).

It is unfortunate that the PS3 is the only vehicle via which one can enjoy such great titles as Ratchet&Clank, WipeOut HD/Fury, and Uncharted. It is insult to their greatness to require the user to have to experience but a moment of the steaming pile of crap that is the Playstation 3 user experience.

I did something incredibly stupid this evening.

I assumed that Sony remotely cares about user experience, that Sony understands that their users care about saved game data, and that Sony — after more than a decade in the game console business — might have a clue about how to implement a system.

Boy, that was a stupid assumption.

I wanted to move the PS3 from TV A to TV B. No video; TV B doesn’t do 1080p. No problem; a google search or two later reveals that holding down the power button will reset the video and give you a menu where you can reset the video.

Nope — the closest is restore default settings. An internet search indicated this was the right thing to do. Wrong. The internet was wrong. Very very wrong. Don’t do that. Don’t ever do that. If you want to switch the resolution of a PS3 without losing data, do so on a TV that works with the PS3 in the current display mode first. If you don’t have one, you are screwed. Sony? Why do you hate your users?

In fact, what it does is worse than restoring the system to factory default. The first sign of trouble is when the PS3 says something like “Hey, I discovered there was user data I didn’t know about, I restored it”.

It lies.

It actually creates disconnected, unsigned, unblessed, shell accounts that have your data in an unusable form. They will have an asterisk in front; bbum became *bbum.

Uh oh.

Upon logging into the faux-*bbum account, many things are now broken. The worst — the single biggest insult — is that the original save game data is still there, but many games can’t use it.

Assasin Creeds II? Apparently, that saved game data will still work. Peggle? Nope, not so much. Oooh.. joy… looks like all data related to games purchased from the playstation network is trashed. WipeOut HD? Won’t even launch — key file missing, redownload dumbass user! But, Sony, All I wanted to do was make it work again? Why are you throwing rocks at me?

Better yet! When you redownload, the PS3 downloads all the bytes and then says “Hey, man, you already got the same crap installed. Do you really want to install it again?” The stupid. It burns!

Now, logging back into the Playstation Network let me sync my trophies. But there was also some warning that said that I might not be able to earn any more trophies, implying that online play was broken in some fashion. Of course, there isn’t anything that I can find to verify current status.

Wait. I played Peggle once and the challenge modes were locked. Now they aren’t. Huh… what? It appears that I didn’t lose Peggle data, but that something magically triggered the reconnection of the data. I’ll have to assume that it was the WipeOut HD “key” download as that seems to be the only “user authing data event” to have happened.

At this point, I renamed the account and have restored Playstation Network connectivity. I may or may not have a mostly working account. I have lost data — all Peggle data gone and deities knows what else. Even getting back to this point was a bunch of effort that I wouldn’t wish upon a non-admin user any day.

Of course, that I failed to maintain a backup was definitely a fault of mine. Then again, I didn’t actually lose any data, Sony just went to great lengths to make my data unusable without actually modifying it.

Or not. It might be that my data is now fully restored and usable. Or it might not be. There is no way to tell. Who knows? I might decide to fire up Uncharted One later this year only to discover that I can’t load the game save and have to start over.

Sadly, this abusive user experience is not unique to the PS3. I had a similar experience with the Wii, though — to be fair — Nintendo has apparently addressed that exact issue in the interim couple of years.

3. objc_msgSend() Tour Part 3: The Fast Path
4. objc_msgSend() Tour Part 4: Method Lookup & Some Odds and Ends

In the first three parts, I gave an overview, explained a bit of the ABI used by Objective-C, and took a near instruction by instruction tour of what happens on the fast path of Objective-C method dispatch. By fast path, I mean what happens 99.9% of the time; a very fast, no overhead, no function call, no locking, set of instructions that grabs the method implementation from the cache and does a tail-call jump to that implementation.

The slow path is used rarely. As little as once per unique selector invoked per class with a goal of filling the cache such that the slow path is never used again for that selector/class combination. A handful of operations will cause a class’s cache to be flushed; method swizzling, category loading, and the like.

Note that during +initialize, methods won’t always be cached. Yet another reason to not do any real work during +initialize! Read the rest of this entry »

Many months ago, I went from a half inch or greater beard to clean shaven. After a few weeks of dealing with cartridge blades, my lovely wife Christine gave me a very nice double-edged safety razor set. A bit of research revealed that the choice of blade was critical to the experience.

Being who I am, the only logical conclusion was to buy a sampler pack covering the most popular blade and try a new blade each week to find one that I liked (and to actually determine whether or not the brand of blade even matters)!

Now that I’m done, I have encountered a few surprises and amassed a handful of questions along the way. So, in a summary:

Why bother?

If you are going to keep a clean shaven face, a double-edged safety razor strikes a nice balance of price optimization and performance.

First and foremost, the quality of shaved produced by a double-edged safety razor is way beyond that provided by a cartridge razor. Notably, my face stays clean shaven for far far longer. With a cartridge razor, an 8 a.m. shave would lead to a rough face by 4 p.m. With a decent double-edged blade, I still have a smooth face 11 p.m. Beyond that, my skin is a hell of a lot less irritated.

Conveniently, it is also comparatively cheap. Cartridge blades are stupid expensive — dollars — whereas a decent quality double-edged safety blade is all of about 6 cents per blade in bulk.

To achieve a decent shave with a DE safety razor requires paying a bit of attention and taking things a bit slow. After a few weeks, it becomes a bit of morning ritual… a bit of calm amongst the storm that is my life.

Which razor am I using and what cream?

The one at the left. It is a relatively plain Merkur straight safety razor. It is of medium weight and not that aggressive (i.e. the space between guide and blade isn’t that wide). Feels good in the hand and is easy to clean.

Before the shave, I use a bit of oil rubbed into my face. As for cream, I’m using the house brand from the art of shaving applied with a badger hair brush. Works well enough, but I’ll probably try some others as this runs out.

As a part of our ongoing home improvement adventure, we are installing solar panels. Between the state and federal rebates, the increasing cost of electricity, and the improvements in solar technology, it is an investment that will pay for itself in a decade or two. Maybe less, if California really starts paying for excess production.

And, of course, Solar scratches my techno-geek itch. In particular, the system we are installing uses per-panel micro-inverters that leverage IP-over-powerline to network with each other to synchronize phase and deliver power back to the grid. As well, it makes the system easily expandable in that we can drop new panels in without having to replace a costly single inverter.

Apparently, when this is all said and done, I’ll have access to a web site with a set of schematics that show our panel layout along with individual and overall power generation statistics.

Of course, being that we live in an Eichler, the path between concept and final installation has to have at least one adventure.
