Starting late 2010 the PowerFLARM traffic awareness and collision avoidance product will be available. This will be the first FLARM product available in the USA. Flarm is well proven technology overseas and this is very interesting for glider-on-glider and glider-on-towplane collision avoidance in the USA.

The PowerFLARM dimensions are

• Width: 96 mm / 3.8 inch
• Height: 46 mm / 1.8 inch
• Depth: 94 mm / 3.7 inch

I think the renderings on the PowerFLARM web site makes the unit look slightly larger that it will really be. And as other have pointed out people may be assuming the that slot on the front of the PowerFLARM is an SD card slot when it is a microSD slot. I was giving a talk a few months ago on collision avoidance technology (transponders, ADS-B, Flarm, etc.) and wanted to show the actual size of a PowerFLARM device. There are no devices available quite yet so I made a foam core model and took that along to the talk. I just a shape cut out on the table saw and glued an image from the PowerFLARM web site to the front face. (more…)

I am no longer on FaceBook and I do not want to receive any invites. I’ve was getting frequet  email spam from FaceBook reminding me to accept friend invitations  – repeat emails for invites where  I’ve already accepted those people as friends many months ago. I wonder if this is just happening to me? The email preferences panel crashed when I tried to save changes, and I should not need to be controlling this by setting preferences. Sigh.

Oh I really hope they are screwed.

I was looking at the Apple Macbook Pro updates announced at the recent 2009 Apple Worldwide Developer Conference. The MacBook Pro reduction in I/O connectivity is getting depressing. The 15″ and 13″ models get an SD card slot but they do so at the expense of an ExpressCard/34 slot. I reminded me of George Orwell’s 1984 “your chocolate ration has been increased”.

At least the SD card slot does support most popular SD size media as Apple clarifies here.

The MacBooks Pros have too little I/O connectivity. Yes I know Firewire 800 is great, but I thought these were Macs for professionals, not PC laptops. Now the 13″ and 15″ models have a single FireWire 800 port and two USB 2.0 ports and an SD card slot and that is it. And yes I know you just can’t count ports to measure really usable I/O performance but the sheer physical connectivity alone of the older MacBook Pros was very useful.  FireWire 800 is great but many high-end users need e-SATA based RAID connected via an ExpressCard e-SATA adapter or for various other wireless connectivity or other uses. The 17″ MacBook Pro has an ExpressCard slot and is a great laptop but it is also a bit too big for many users. Adding an SD card slot and keeping the ExpressCard/34 slot would have been great – or they could have even bundled an SD card reader if they needed the marketing claim for SD card support.

I live and die based on my one year old 2.5GHz 17″ MacBook Pro with 3 x USB 2.0, FireWire 400, and FireWire 800 and an ExpressCard/32 slot. A great laptop. And it usually has a SanDisk Multi Card Reader  in the ExpressCard/34 slot. That reads more types of media (if anybody cares about Sony MemoryStick Pro)  than the SD card slot built into the new MacBook Pros and much more importantly when I remove it I have an ExpressCard slot for other uses.

I am curious if Apple implemented a really fast SD card slot or if it works via USB 2.0 (like the SanDisk ExpressCard/34 adapter I use). Still that would not make up for losing an ExpressCard/33 slot.

Oh well with the matte screen only available as an option on the MacBook Pro 17″ many photography and video professionals and serious amateurs will see that as the only portable computer from Apple they can use. I thought at some time a matte screen for the 15″ MacBook Pro would appear.  I take that as more consumer apathy or ignorance about color and color management than Apple making bad decisions.

This is some very obvious Monday morning quarterbacking. But I am extremely negative about Sun Microsystems. I think Sun’s board is crazy for not taking the IBM $7B acquisition offer.  Maybe they think they can pull something better off, but it is hard to think who that suitor could be and why they’d value Sun at more than $7B. Sun has been churning though money and has been undergoing endless changes for ages. And while there have been occasional better days; the slumping economy must be hammering them and overall they are on a downward spiral to irrelevance. A sad outcome for this once strong Silicon Valley company. And now that an acquisition has been so publically aired that’s got to further hurt potential customer willingness to buy into Sun’s future.

The shit storm that Sun is about to be dealt from stockholders and their lawyers is going to be interesting to watch.

I had a great early season soaring flight out of Williams Soaring Center on March 1st, with an over 4 hour, 460km flight along foothills on the eastern edge of the Mendocino Mountain range. This was a chance to try out my SPOT Satellite Messenger again. The SPOT messenger is capable of sending manual “OK” and emergency messages my interest is using the messenger in “SPOTcast” mode where position reports (latitude, longitude and time, but not altitude) are sent automatically every 10 minutes.

SPOTcast messages are available on the SPOT website but unlike the manually sent messages they cannot be sent through email or SMS messaging. There is no ability to preview the web site before you purchase a SPOT so people often believe the SPOT web site can do a lot more than it currently does, and for example people assume that the SPOTcast messages get automatically displayed on a map and updated as new position reports come in. What is actually available is much simpler, current SPOTcast messages are displayed in a table, you select the ones you want plotted and click a button to plot on a Google map. See images of this user interface in my previous blog post on SPOT.

The SPOT messenger appeared to work flawlessly, as it has previously. An interesting recent addition to the SPOT website allows the SPOTcast reported locations to be saved in Google Earth kml file or GPS Exchange (GPX) formats. If you are interested in playing with this in Google Earth, here is spot_messages.kml the file containing the SPOTcast position reports from the SPOT web site and 831c4fv1.kml the kml flight trace produced from my flight logger submission to the OnlineContest (OLC). Just open both files in the same Google Earth session and you should see them overlaid as in the large screen shot image linked to the thumbnail above. In Google Earth you can click on each square “Track” point to show the corresponding time and latitude and longitude coordinates.

I’m still on my first set of Energizer AA Lithium batteries after several flights of several hours each. So while I’d have prefered the ability to use external 12 volts DC power, it does not look like battery life is an issue.

I’ll write up some more comprehensive comments on the SPOT satellite messenger soon, but in the meantime I wanted to provide some screen shots of the SPOT web site showing what is available from the optional SPOT Track Progress service from SPOT. Overall I’m impressed by the SPOT messenger and I will be using it in my glider, particularly when flying in remote areas to automatically track my location and as a supplement to my existing McMurdo Personal Locator Beacon (PLB). I purchased my SPOT messenger from my local REI store, it is also available at REI online.

SPOT is a subsidiary of Globalstar, the satellite phone company. The SPOT satellite messenger has an internal GPS receiver and sends the GPS coordinates and message type info via the Globalstar L-band simplex data network. Message types available are an automatic tracking message, or manually triggered events – a “911″ distress alert, a less severe “help” message or just an “OK” message.

So one of the neatest things Yahoo owns is Flickr. But I’m at a loss to understand the snails pace of innovation at Flickr. There is tons of stuff the could be doing with new features, tools and integration. But anyhow instead of wasting space on that I’ll just whine about Flickr Uploadr 3.0 — the down-loadable utility that is supposed to make uploading photos easier, well previous versions did, the current one is just broken.

Build 3.0.2 at least is broken on Windows XP SP2. Starting with the big one – the actual button to upload images never appears, oops bit of an oversight there. And lots of sloppy UI things — like not having any rollovers/hints in the UI. And when you view Upload>Preferences but don’t change anything you still get a dialog box saying you changed preferences and asking you whether you want to apply those changes to the current photos. Dragging the main window frame out larger and smaller shows strange behavior of an horizontal scrollbar on the right panel if you resize the window enough to have a vertical scroll bar on the right panel. Don’t they know how to do basic UI QA? There appears to be other strange things going on as well. The vertical partition between the panel should be re-positionable. And on and on…

How do you mess up something so simple and then actually want to release it?

Santa wears a black turtleneck and he is giving his usual keynote at the MacWorld conference on January 15th. I decided to hold off on a Macbook Pro purchase hoping to see an upgraded model coming. I need a high end machine for multimedia work, overall desktop PC replacement, including running VMware Fusion.

My MacWorld wish list would be for a 17″ high resolution screen model, with

• Intel Penryn procesor (6MB L2 cache) at 2.6 GHz
• An internal dual layer Blu-ray superdrive (ultradrive?), I guess that would make it something like a BD-RE/BD-R/DVD-R/DVD-RW/DVD+RW/DVD/CD-R/CD-RW/CD optical disk, phew. The ability to play blue ray movies would be a bonus (but not required). Fastmac already has an aftermarket Blu-ray drive available for the MacBook Pro.
• Increased express card connectivity. Ideally two seperate ExpressCard universal slots instead of the single /34 slot in the current MacBook Pro models.  Universal slots accomodate /54 as well as /34 cards. I suspect there would actually be space to put two universal slots on a 17″ MacBook Pro. Failing that one universal and one /34 slot would do. These would give me the ability to carry around an expresscard/54 CF Card reader (for my Digital SLR camera) internally in the universal slot and an expresscard/34 SATA-II controller for hooking up lots of disk for video editing. I’d like Apple, to at least make the single /34 slot a universal slot.

C’mon Santa I’ve been a good boy can I please have these wishes

I stopped using a deskside PC about two years ago and like having my whole computing life in one place on a laptop. I’ve been thinking over what to do with my current ThinkPad T42 laptop which is just too underpowered for what I need. High on the list is buying a MacBook Pro and making the switch back to the Macintosh as a primary computer. Part of wanting to upgrade is driven by lack of disk space on the ThinkPad T42 and part of it is driven by wanting more horsepower and memory to run Photoshop on larger images and to do video editing. For video I have an old copy of Adobe Premiere 6.5 and I’ve been leery of upgrading this on my ThinkPad since most people I know who is doing video are working with Final Cut Express or Final Cut Studio on a Mac.

I’ve been looking at different options and thinking about the switch. Just some of the software I use is shown in the photo above. I thought it might be interesting look at switching from a Windows laptop to a Mac with a reasonable number of applications and so I thought I’d write about some of the experiences. Bottom line is it is going to cost me about $1,200 in software upgrades/cross grades and software relicensing to move to the Mac, and that is without a big splash on something like Final Cut Studio. I wish Apple had a program where I could get an upgrade credit for Premiere to Final Cut Studio, that would make the whole decision pretty automatic. Which will make the purchase of a high-end MacBook Pro something like a $4,700 purchase – Yikes. Sure I get a platform that can do a lot more, especially with video editing, but it’s interesting just how much it costs to move. Time costs of lost productivity and relearning things is going be significantly higher than a few thousand dollars but I look at this as having to bite the bullet some day.

Obviously any switch made easier with the availability of VMware Fusion and SWSoft Parallels Desktop. Don’t expect me to be impartial here, I’ll be using Fusion and I think it is a lot more stable than Parallels Desktop. But both Fusion and Parallels will perform much better than the old Connectix (now Microsoft) VirtualPC did on PowerPC based Macintosh systems.
