amateur hour

I volunteer for a neighborhood organization. I run all the neighborhood business from a dedicated iPad Mini 3 with LTE. An earlier experience with a 'rugged' ZAGG keyboard had me nearly ready to chuck keyboard, iPad, and iOS.

A new keyboard has me hanging on for a bit longer. That keyboard is the awesome Logitech K480. Every surface is hard plastic. Every plastic edge is a bit sharp. The thing weighs in at just over 800 grams. That's 100 grams more than an original iPad! The whole thing seems like it could be an entire 80's 8 bit home computer by itself.

The best part is the Mike Mulligan-esque 'Bing Bang Crash Boom, Louder and Louder, and Faster and Faster' sounds you get when you slap the keys around. The second best part is the serious slot in the back. It will hold an iPad mini in portrait with a smart cover folded behind it. An iPad mini in portrait has almost as much vertical real estate as an Macbook Pro Retina 13.

The K480 keyboard can do one trick more. It has a chunky dial on the side that picks which of three paired devices will receive input. The slot will hold an iPad mini and an iPhone 6 together in portrait.

The K480 is happy to pair as a keyboard with essentially any bluetooth machine. This means that it has an actual physical key with the blessed letters 'e', 's', 'c' silkscreened right on.

I downloaded and installed iOS 9.3 on the iPad mini after yesterday's iPad Pro announcement. I hoped a extra bit of Pro-ness would somehow permeate the iOS line. I hoped that iOS would stop taking virtual acetone to the escape key. No such luck. This Pro operating system still hides the escape key from 'keypress', 'keydown', and 'keyup' events in Javascript. Amateur hour.

With the new iPad Pro 9.7, Apple has caved on a physical keyboard and a stylus for iPad-sized tablets. When will they end their war on escape? I don't need 1024 levels of escape. I don't need to know the angle at which I press escape. I don't need John Lasseter to say that it's the most realistic escape ever. I just want escape.

bargain

I wrote last time about my experience with a bad iPad mini keyboard. I talked a big game about dumping it in the ewaste box but it didn't actually make it there until yesterday. It's not coming back out.

Unfortunately, the matching iOS app 'Prompt' can't actually be physically thrown out so easily. The combination of poor keyboard, poor app, and beautiful iPad left me in actual tears for a moment yesterday. That's when my position on Apple vs. FBI changed totally.

I had been vaguely pro-Apple in the San Bernardino dust up. I thought that Apple had been too slow to adopt a real secure element and that they would wind up helping the FBI. It would then fall to them to never got caught in that situation again.

My new position is simple. Manufacturers shouldn't be made responsible for the programs or data in computers. Manufacturers should not be compelled to speak -- through programs or through generating non-repudiable signatures for another's programs. A consumer or a court can easily tell if an electronic device is this kind of computer. A computer allows the owner or user to load any program or data they choose without qualification or restriction. Computers have manuals, specifications, or program source codes that describe their operation. Period. iPhones and iPads are not computers.

A compound electronic device may contain a computer available to a user. Examples include computing systems comprising a kernel and user environments where the manufacturer restricts the ability of a user or owner to load new kernel programs or certain user programs. Here, the user environment may be protected. If the vendor restricts the loading of new kernel programs or data through digital signatures, through other technical measures, or through failure to furnish a manual, spec, or source then let them comply with arbitrarily fanciful orders for those portions of the system which are not a protected computer.

An AVR-based Arduino? That's a computer. A Commodore 64? That's a computer. A Thinkpad? That's not a computer. The Libreboot x200 (itself a remanufactured Thinkpad)? A computer! Today's Tivos? Not a computer. Today's smart fridges? Not computers. Essentially everything in the IoT? Throw it all under the bus.

If a company wants to sell you a walled garden -- then let it be known that there will be snakes. A company that actually respects your privacy will sell you a real computer.

Phones and telegraphs have been monitored almost since their invention but the specter of typewriter registration in Ceausescu's Romaina remains morally repugnant almost without reservation. Smartphones with signed firmwares are no different than telegraph lines. Real computers represent the typewriter and freedom.

I dare Congress to pass legislation forcing manufacturers to help with electronic devices. Provide an exception for true computers. Protect the right to build and sell true computers. Allow manufacturers to 'upgrade' devices to true computer status by publishing specifications and keys instead of complying with orders. Then I dare Apple and everyone else to build and sell us those computers.

Richard Stallman has had this part right all along. Who knew that a terrorism investigation, not a DRM lawsuit, would be the best test case in a generation?

reograph: backlog two

Reograph lightning review: ZAGG Rugged Book Case for iPad mini

Do not buy.

Did you get an iPad mini for Christmas instead of a cheap and chunky Chromebook? Don't worry. For only a few dollars more than the cost of the cheapest Chromebook ($99), ZAGG will sell you a poorly made 'rugged' laptop-type keyboard case for your iPad that will have you exchanging homemade candles instead of electronics for Christmas for a decade.

The box claims a year or more of battery life. Good news. The Micro-USB charging jack on mine is so poorly aligned with the rubber surround that I wouldn't want to charge it more than about once a year. The whole thing is a rubbery iPad case, some magnets, and a rubbery iPad keyboard thing that merge into a two-part iPad laptop Voltron deal. We're not talking spaceship Voltron. We're not even talking lion Voltron. We're talking 'Voltron Off Broadway' pantomime horse Voltron. It assembles in a variety of ways.

Mode one is Cheap Laptop Mode: The one key is smaller than the two key. Plus doesn't get its own key. Making a pipe symbol takes three keys. On the other hand, literally, tilde also takes three keys. RSI risk is one thing. This keyboard makes the UNIX gods very angry. You risk their wrath when you bang on this keyboard.

Mode two is 2001: A Space Odyssey Mode: The keyboard folds to cover the screen. The assembly resembles a slightly rubbery monolith. This mode is where the ZAGG Rugged Book Case shines. It appears totally inert. Mine may have sent a bluetooth signal in the direction of Jupiter (or Saturn, if you're _that_ kind of Clarke fan).

Mode three is Reverse Cowgirl Mode: The iPad pops off, turns around, and pops back on facing away from the keyboard. I think some other tablets call this 'tent mode'. I can see that. The difference here is that the keyboard remains fully armed and ready for something to fall on the delete key and eat your entire product review. Most of the other tablets have the decency to shut the keyboard off when they know it makes no sense. The ZAGG could easily have detected the orientation of the iPad and turned the keyboard off. It doesn't.

Small Chess Playing Dwarf Mode: This is exactly the same as Reverse Cowgirl above. The difference is that you hide behind iPad screen and type messages on the keyboard to the delight and amazement of your audience. The larger iPad Air version of the case probably works better for this mode unless you can really scrunch yourself down.

WTF Mode: Here, the still active keyboard folds behind the iPad. You hold an assembly about four times as thick as a regular iPad. The on-screen keyboard will not appear because you have a paired, active, bluetooth keyboard hidden behind the screen. The power key to turn the keyboard off is also hidden behind the screen.

St. Denis Mode: Here, you rip off the keyboard assembly and chuck it in your bag. Then you pull it back out of your bag when you realize it is still paired. Then you turn it off. Then you chuck it back in your bag. Then the unprotected power key is hit and the rest of the ewaste in your bag presses the delete key and nukes your entire sinful Valentine's Day letter. St. Denis is said to have carried his decapitated head under his arm for a ten kilometer walk while preaching repentance all the way. With the ZAGG, the disembodied keyboard can actually repent for you while you walk. Handy enough.

My ZAGG came in a box packed with the manual, in English and French at least, that was actually for a similar product for Samsung tablets. From what I can make out, only the French portion of that manual actually references St. Denis.

Ewaste Mode: This is fast becoming my favorite. Here it sits in your ewaste box. The unprotected power switch and the non-removeable battery that lasts an entire dog's adolescence means that you had better unpair your iPad or you're in for a up to a year of random keyboard events.

pour over

I filled the carafe of my coffee maker with ten cups of water. I put 60 grams of Finca Mauritania into an unbleached #4 paper filter. Then I poured the carafe of water straight into the hopper of my Mazzer Super Jolly coffee grinder. Oops.

I disassembled most of the machine, dried it, and then put it back together. I ran it for about 20 minutes to dry it out. This was not enough to keep moisture from rusting the upper bearings over the course of the next week.

The District of Columbia offers many things. Large birds are returning to the Anacostia. Organic produce abounds. Chocolate and gin are made in DC mere blocks apart. Beards are omnipresent. Despite this bounty, the District of Columbia remains a bearing desert. I couldn't find a stocking dealer of the necessary 6202-2Z bearings anywhere in the city.
 
Amazon came to the rescue with a pair of suitably Italian SKF bearings. The padded envelope slipped right through my mail slot this afternoon. The grinder was purring an hour later.

I don't know if bearings and fellow travelers can be reintroduced to DC with any less effort than it took to bring ospreys back to the Anacostia. I wonder often if DC can support the kind of specialty retail trade that it takes to support hardware needs beyond the fastener aisle of the local hardware store. I wonder how to start. My current thinking is that DC could certainly support a few arduino/maker/hacker vending machines. I would certainly use them.

your move

Last month brought the new Chromecast Audio. I like mine just fine though not quite enough to displace any of the existing Airport Express devices in my house. Last month also brought Apple's El Capitan to my machine.

With El Capitan's Safari 9, Apple appeared to say 'your move.' to Google and their Cast extension for Chrome by breaking iTunes' 11-year stranglehold on official desktop app support for Airplay. What Apple actually said was 'your mo... oh, dear. i've soiled myself.'

Apple's otherwise great new webkitShowPlaybackTargetPicker() media element method lets web content sling itself to Airplay without obnoxious extensions or API keys. Awesome. The resulting Airplay picker popup -- triggered from an audio element here at reograph labs -- shows
exactly none of the Apple Airport Express devices installed around the house. An old Apple TV and a third-party Airplay server running on a Mac put in an appearance but that's it.

I don't know whose move is next but I'm getting tired of this game. System-level mediated audio made sense in the past when the system actually multiplexed audio streams. Essentially none of my audio today except the terminal bell is routed to a DAC attached to a bus in my computer. How is Apple struggling with a feature that worked with iTunes on my G3 iBook?

Is this perhaps a sign that the old Airtunes-protocol hardware is on the way out? Does the bulky new Apple TV create room for a Chromecast Audio-like Apple TV for the Blind? You heard it here first.

ewaste pda style

Back when PDAs were a thing, I owned one of just about every interesting device. Psion? Yeah. Palm? I had a half a dozen. Newton? Check. Sharp Zaurus? Check. MagicCap device? Got it. Franklin REX? These were the mainstream machines. I had a dozen of the weird ones as well. The worst of those was probably the Agenda VR3.

The Apollo program closed out 1972 with humanity's last manned mission to the moon so far. The eight year lull before Shuttle launched in 1980 seemed like an eternity though Skylab and Apollo-Soyuz took a bit of the edge off.

The PDA market had an Apollonian slump between the release of the last terrific PDA (1999's Palm V) and the release of the original iPhone in 2007. Weird things turned up in the market during that time but they really only ever took a bit of the edge off.

I needed a fix of personal digital love in 2005 and jumped on the new Nokia 770 with vigor. It is hard now to explain why in terms other than a fix. It was perhaps the first PDA-like thing to come with a kernel that supported the Plan 9 file system protocol. Maybe? That seemed breathtakingly important at the time. It also seemed like the perfect platform to run Paul Guyot's Einstein emulation of the Newton. Your PDA platform may have problems if a Newton emulator seems like a high calling.

I can't say that it was awesome, or that it seemed awesome. It seemed then that it would eventually be awesome. And then it wasn't. It was a preview of modern high-DPI displays. Its 4.1 inch screen rocked 225 ppi at 800x480 two years before the iPhone rolled up with the retro resolution of 480x320 at 163 ppi. It was unlocked. It was the first PDA I owned to run a real web browser. It was interesting.

The 770 was easy to tether to a bluetooth phone and I used it this way until I had owned an iPhone for about 15 minutes.

It was beautiful and well made. My copy was made in Estonia, an ancient Baltic country taken as part of the Soviet Union until 1991. That's as close a PDA analogy as I can make to Apollo-Soyuz. It was a relative heavyweight. Mine weighs in at 235g. My iPhone 5s weighs in at 112g. The Palm V weighed 114g.

An old joke says that the Americans spent a million dollars to develop a pressurized pen capable of operating in outer space while the Soviets simply used a pencil. The tale is reversed with the 770. Nokia spent a lot of money to develop the last of the resistive/stylus machines when the Americans, here Apple, simply used a finger.

My 770 goes off to recycling today with its original stylus still tucked safely in its slot.

chromecast audio

I wrote this morning about my disappointment streaming simple audio from a Chrome tab. I placed the blame, correctly, on Chrome and not the Chromecast but I may have been a bit harsh. I may have blamed son Chrome for the sins of father Google.

I've now had a Chromecast audio in my hands for about a half an hour. It is much less horrible than its video cousin. The SDK is still broken by design. The Cast Chrome extension is still very large and complicated. It still required my phone, and not my Macbook, to configure.

If you set aside the setup, the pointless cryptography is pointless but only modestly worse than Apple's scheme in Airplay.

Our beloved RMS used to say that it wasn't really important to have the source to the firmware of a device that behaved like a circuit. An OTP PIC micro controller pretending to be a quad NOR gate was as good freedom-wise as a real quad NOR gate. The audio Chromecast works almost as transparently and reliably as an old 900MHz wireless speaker and I'm prepared to treat it as a circuit for now.

I stand squarely behind the rest of this morning's rant. The browsers with native APIs are the only local, graphical, general-purpose platforms worth programming. I look forward to the day that my web app can stream to a Chromecast, or an Airplay, directly without obnoxious SDKs or extensions or App IDs or the cloud. Until then, I'll listen to some tunes.
