Is it Worth It to Use a Hub Dynamo for Bikepacking?
(posted on 22 Aug 2023)

I've used a SON 28 dynamo, a Busch and Muller E-Werk converter, and a small
buffer battery for about 6 years. Travelling at 17 km/h, you get about 2.5W,
500mA@5V for charging USB devices. I carry 2 x 13,000mAh Anker battery banks. So
to fully recharge one of those batteries, I have to travel at 17 km/h for at
least 26 hours, and that doesn't account for inefficiencies in the charging
process, so more like 30 or more hours.

My average speed on long multiday bikepacking trips is roughly 11 km/h (I'm not
fast). That's fully loaded (35 kg/ 77 lb bike, gear, water, food) with lots of
climbing, so sometimes that speed is more like 5 km/h going uphill and sometimes
30 km/h going down. So a rough estimate is that charging one of those batteries
will take about 40 hours of typical riding. That's 3-4 long days. With my setup,
charging an iPhone 13 Pro, Hammerhead Karoo 2, Bluetooth earbuds and batteries
for my point-and-shoot camera, I can stay fully charged for about 2 days per
battery bank. So with 2 battery banks, I get 4 days and possibly as much as an
additional 2 days from charging from the dynamo. Or another way to look at it is
that I extend my time by about 50% without any recharge from an outlet.

You can extend the usefulness of the dynamo if you are more careful than I am
with a phone and if you have a more energy-efficient bike computer than the
Karoo.

If I were making the decision on whether to use a hub dynamo, given what I know
now, I'm not sure I would. In my bikepacking, I've rarely gone more than about 3
days without finding some way to plug into AC power and recharge. The one thing
that might still tip it over to a "dynamo yes" is that you can always have
power, however meagre it is. So if you need to ride at night or need to charge
your phone to get some signal, you can generally make that happen, at least if
you are not going uphill!

This is definitely a "your mileage may vary" situation, but at least I can
provide a long-term example.

Why Should the Vaccine Hesitant Get Vaccinated
(posted on 13 Sep 2021)

The vaccines are not 100% protective. Some of the Covid vaccines are the most
effective vaccines ever produced but it seems that about 5-30% are not as well
protected as we would like depending on the specific vaccine used. And without
more tests, no one knows if they are part of the 5-30% who are not as well
protected. These vaccines do seem to be more effective at protecting against
hospitalization and death. I don't have numbers on the top of my head (and I
don't think we have good numbers yet) but there is still a more than an
insignificant chance that a vaccinated person will die of Covid.

So if a person with Covid, vaccinated or unvaccinated, interacts with a
vaccinated person, there is a reasonable chance that the vaccinated person will
get covid too. I've seen numbers that put this at about 10% of the chance that
an unvaccinated person would get Covid in the same circumstance.

There are people that for good health reasons, generally allergy-related, should
not get vaccines. These people are vulnerable. The whole reason to try to reach
herd immunity is to protect these and others who won't get vaccinated. I would
expect that anyone who knows that they are not protected should take extra steps
to protect themselves but what would really protect them the most is if there
was less Covid floating around in the community.

A basic fact of virology is that the less of a virus that is floating around,
the fewer chances there are that it will mutate. The more mutations, the more
chance that a variant will arise that current vaccines will not protect against
and we are back at square one. This is a worldwide issue so in theory giving a
vaccine that one person refuses to take to another person in another part of the
world is just as effective against mutations. From a practical perspective, a
lot of vaccines in the US are being thrown out because they expire unused. They
are not being shipped elsewhere.

One of the main things that public health officials worry about with a pandemic
is overflowing the healthcare system. People with unrelated illnesses are dying
because there are no emergency services available because they are being used up
by Covid patients. So unvaccinated people who get seriously ill from Covid are
putting the whole community at risk by using up resources that would not have
been used if they had been vaccinated.

So I think that the best reason why an unvaccinated person might consider
getting vaccinated is to help protect those around them, vaccinated or
unvaccinated. Personally, that was my first reason for getting vaccinated when
the opportunity came up. I wanted to help protect my community. Even though I am
older and have some health risks, I still felt that the very minimal risk I was
taking was worth the reduced risks associated with Covid to me, my extended
family and the overall community.

If it were just a matter of only the unvaccinated get seriously sick and dying
from Covid, I'd still implore them to get the vaccine for their own sake but it
goes way beyond that.

Organized Disinformation Campaigns on Facebook
(posted on 1 Sep 2021)

I don't normally venture into the cesspit that is a Facebook discussion on
anything political but recently I've been researching how people behave in these
discussions.  I've noticed some interesting patterns.

When a hot topic like politics, covid vaccines, or masks come up it is
descended upon by a huge number of anti-vax/anti-mask identities
posting ridiculous, slanderous, and disgusting comments.   From time to time
I've engaged some of these identities to see how they will react.  When I post a
link to a credible source like the US CDC website and these will quickly get
taken down by Facebook due to "spam".  Any human would recognize that these are
not spam but these identities understand that they can gang up and mark a post
as spam and remove any credible response to their disinformation.  You can
dispute the comment being marked as spam but Facebook will not reinstate your
comment.  Of course, being marked as a spammer a couple of times makes me
concerned that Facebook might suspend my account, which is exactly what these
identities want, they want to either get you suspended or prevent you from
countering their disinformation.

I use the term "identity" and not "person" because often when I dig into the
profiles of these accounts that are spewing disinformation, they look like bot
accounts.  Often with no information and a generic picture, or with very limited
amounts of information.

Upgrading My Smartphone
(posted on 28 Oct 2017)

Over the summer I decided it was time to replace my iPhone 6 Plus. I had
installed iOS 10.3.3 on it and that had really broken the phone. I tried wiping
out the phone and completely reinstalling everything but with no luck. Apple
should not have pushed that update out to iPhone 6's.  It also had the same
effect on Rochelle's iPhone 5.  My guess is that because both of these phones
have 1GB of RAM (a ridiculously low amount even when the iPhone 6 came out) some
change made in iOS 10.3.3 cause there to be a lot less memory available for
apps.  Apps began crashing and were extremely slow to load. Multitasking (such
as it is on iOS) just about stopped. It became hard to listen to audio while
doing other stuff.  Even Apple's apps, like the settings app, became very slow
to load and sluggish.  All this from upgrading from 10.3.2 to 10.3.3.

I eventually tried upgrading to iOS 11 when it came out but the results were
more or less the same.  Essentially Apple had obsoleted my very powerful and
perfectly usable 2.5-year-old phone.  I do wish that instead of breaking the
phone, they had just stopped updating it.  The phone ran well before iOS 10.3.3.
 I think that they didn't do this because they were still selling the iPhone 6
so they couldn't leave it behind on software updates.

So, with a very strong annoyance at Apple, I started paying a whole lot more
attention to reviews and rumors of upcoming phones.  I was determined not to
replace this iPhone with another iPhone.  My two phones before the iPhone 6 Plus
were Google's Nexus S and Nexus 4.  I liked the Nexus S but I drowned it on my
cross Canada bike trip.  I really liked my Nexus 4.  Neither of those phones was
perfect but I could make them work for me and more importantly, they were very
inexpensive.  With that experience, I didn't really feel locked into the Apple
ecosystem.  I've avoided Apples iOS apps for the most part.  I've been sticking
with Google's apps on the iPhone so a switch back to Android should be fairly
painless.  The big highlight would be that Google's voice assistant is a first
class app on Android instead of being stuck with the practically
useless Siri on iPhones.

My biggest "must have" on the new phone was a good camera.  If it wasn't for
that, I'd likely be happy buying a mid-range Android.  I wanted a phone that got
security and OS updates in a timely manner so that mostly rules out all phones
except for what Google provides.  I also wanted a phone that did a good job of
playing podcasts via Bluetooth.  As the rumors started to come out about the new
Pixel 2's, it seemed like one of them would be my new phone.  They seemed way
too expensive but all the reviewers loved the first Pixel phones and Google has
really been positioning themselves as a head-to-head competitor to Apple in the
phone market.

Once the Pixel 2s was announced, it seemed clear to me that the Pixel 2 (not XL)
was right for me.  I liked the look of the XL but there wasn't enough added
value for the extra cost for me.  I also kind of liked the idea of moving to a
somewhat smaller phone from the larger iPhone 6 Plus.  I bought the Plus so that
it would be easier to read notifications when mounting on the handlebars of my
bike and at the time Android notification didn't work well with cycling.  With
better bicycle computers that show phone notifications on them, this is less
important.  I really loved that both Pixel 2s had the same camera and that those
cameras seemed like they were a big upgrade from the already great Pixel camera.

So I pre-ordered a black Pixel 2 as soon as the pre-orders opened.  With their
protection plan and taxes that came out to a whopping CA$1200 ($900 + extended
warranty + tax)!  That felt like it was at least $200 too high but I really felt
like I was getting a premium, Apple quality level product so I went for it.

On October 23, the phone finally arrived.  Although the phone has automated
transfer software and an adapter, it still took me about 2 days to really
transfer my life over to the Pixel 2.  The phone is fast and the interaction is
nice and smooth.  It really highlighted how much iOS 10/11 has degraded the
usability of the iPhone 6.  My initial impressions were very positive.  I really
like the Android Material Design interface.  It feels much more modern and
usable than iOS.  I like having Google voice assistant come up just by squeezing
the phone or by saying "OK Google".  I also liked being able to look down at the
sleeping phone and see the time and notification icons, and when music is
playing, the name and artist of the song!  Oreo from a design and features
perspective is amazing.

Then I started to use the phone in real life...  I have at least 7 different
Bluetooth devices that I have been using regularly with the iPhone, many at the
same time.  I have a mono-headset for listing to podcasts (actually I have 4 of
these), a UE Roll speaker, a sound bar, a bike computer, car stereo,  a
sous-vide device and another device.  These all have troubles working with the
Pixel 2.  Usually, once I get a device connected and working, they work well but
it's that initial pairing and latter connection that is really problematic.
 When you turn on a Bluetooth headset that has already been paired, I expect it
to just connect to my phone, and if there is something playing on the phone, it
should just start in the headset.  On the Pixel 2 that happens about 50% of the
time.  When you want to switch from one audio device to another, it should just
happen when you turn it on.  Mostly the Pixel doesn't even recognize the already
paired device.  I'll reboot the phone and the Bluetooth works much better, for a
matter of minutes to hours and then it becomes a struggle again.  I ride my bike
with the mono headset and listen to podcasts.  For various reasons, I will want
to pause the playback while riding.  Often when I attempt to start up the
podcast, it just won't.  I have to stop my bike, get out my phone, unlock,
navigate to my podcast app and hit the play button.  On my iPhone, just hitting
the pause/play button on the headset would get the audio going again (although
Apple did have a nasty habit of playing the Apple Music app, which I never used,
instead of the last played app -- it also always played the same song).

Looking online, I see that Pixel 1 and Pixel 2 owners have been struggling
with Bluetooth for a long time.  Google has promised fixes but I'm starting to
see that Google has a lot of fixes to do on the Pixel 2 (particularly the XL
version) and Oreo so I won't hold my breath.

Something that really surprised me is that I couldn't find any way to just
switch audio from one connected Bluetooth device to another or the phone
speaker. iPhones have had that feature forever and I used it all the time.  It
was such a time saver for me.  It really seems to me that Google developers have
never properly tested or used Bluetooth with multiple devices connected or
paired.

I also found that if I was listening to Bluetooth audio that I could not connect
my Bluetooth bike computer.  I would have to reboot the phone to get that to
work.

While out on a ride last week, I was looking for interesting things to take
pictures off to test out the phones amazing camera.  On one occasion, I pulled
out the phone, hit the camera app, it started up and then I waited for the live
image.  And I waited.  And I waited.  About 30 seconds later, the camera app
crashed.  I tried again.  I waited about 15 seconds and finally, the camera app
became responsive and I took the picture.  I haven't seen this problem since but
I have seen a lot of different apps crash.  Overall, the apps seem to be
somewhat unstable.  I'm sure that will improve as Oreo is updated but should I
wait?  I thought I was buying a premium product, not a developer beta.

While no one has been complaining about the Pixel 2's screen (unlike the
avalanche of complaints about the XL screen), I did find it a serious step down
from the 3-year-old iPhone 6 Plus design.  The screen was less bright and
greyer.  When you looked at a bit of an angle, the colour changed slightly.  At
larger angles, you get a rainbow effect that I thought went away on LCD screens
a decade ago.  I also found the brightness of the screen would change from
moment to moment and that was very distracting at times.  I suspect that the
auto adjust for brightness isn't tuned well, but why isn't it?

There has been a lot said about how great a camera comes with the Pixel 2.  It
does take some really good pictures but have a look at this panorama image that
I took.



It's the worst panorama image that I've ever taken.  It looks like the camera
didn't do any post-processing of the image.  Other panorama images were the
same.

So after almost a week with this phone, I've decided it's got to go back.  It
had a lot of promise and if cost CA$600 instead of CA$900 (and if Bluetooth
worked better) I would keep it.  It's just not the premium product that you
would expect for $900.

So this begs the question, what smartphone should I  get?  My iPhone 6 Plus has
been almost unusable since August but I waited until the fall announcements
completed before making a choice.  So what's my second choice?  I might go for
a OnePlus 5.  It's got amazing specs and price and supposedly it's gotten its
camera issues ironed out.  But as is typical with OnePlus, all their phones are
out of stock.  How does OnePlus survive?  I could go for a new Moto G or X.  The
reviews are good and they are quite reasonably priced but the camera is the big
sticking point.  They all seem to have mediocre cameras.  Also, if Oreo on a
Pixel is this bad, is it likely to be any better on a second-rate phone? 
Samsung phones sell well and they seem to make really good hardware. 
Unfortunately they really "crapify" their device and don't update them
regularly, even for security fixes.

So that leaves me going back to the evil empire of Apple.  I ordered an iPhone X
at 12:05 am on October 27 just in case.  I figured I could cancel the order or
flip the phone if they are in as much demand as it looks like they will be.
 With AppleCare and taxes, it comes out to about $1760 for the "low-end" 64GB
model.  That's more than I've paid for any Windows computer in about 25 years.
 A similar iPhone 8 Plus is a more reasonable (??) $1410.  I like the more
compact form factor of the X but the FaceID and other faddish features scare me.
 Apple is kind of betting the farm that FaceID will take off and people will be
willing to pay a massive premium for it.  I have my doubts.  If all that
technology was on the back of the phone for augmented reality use, it might be a
game changer, but it's not. 

Reports are that the 8 Plus is not selling well.  It's no longer in fashion with
its 4-year-old design.  Those sales might pick up once people realize that they
won't be able to get an X before the end of the year.  I would be afraid to go
for the iPhone X.  Apple has had a lot of problems with newly introduced
technologies lately and the X has a lot that is new.  I can see a lot of
failures in its future.  The iPhone 6 Plus was new tech when it came out.  I had
to have my replaced twice due to screen and battery failures.  Because Apple has
perfected the 8 Plus form factor, I bet that it will have very few failures. It
may look dated but it's likely to "just work". And isn't that one of the main
reasons people buy Apple products in the first place?

So it looks like I'll be going back to Apple and the iPhone 8 Plus.

Switching to OSX, Another Attempt
(posted on 18 Aug 2014)



Almost exactly 5 years ago, I experimented with using a Mac as my main software
development platform. The net result was that I abandoned the effort after
finding too many obstacles and not enough benefits. In the 5 years since, the
Windows and OSX platforms have converged considerably and the kinds of software
that I work on have become much more "cloud like" in nature. There has also been
a slow transition from Windows first to OSX first development tools to the point
where many libraries that I want to install, either don't work under Windows or
are a real pain to install.

So I am again diving head first into the OSX ecosystem. This time, I've got a
top of the line, refurbished Macbook Pro that was shockingly expensive at about
3 times the cost of my last high performance Windows laptop. At least
performance shouldn't be an issue. It's also nice that I can plug 3 external
monitors into this laptop so that I can roughly reproduce my 6 screen setup that
I had previously.

So far things have been going pretty well but I've not gotten too far in
reproducing my development environment. That's my goal for this week. I'll
report on the progress that I make.

The Complexities of USB Charging
(posted on 11 Jan 2014)

A friend wrote me with the following question:

> Geoff, a woman I know told me that she heard that charging one's iPhone via a
> USB cable from a laptop does not provide it a "full" charge and that the only
> way to fully charge it is via the AC adapter and USB cable.

While she is technically incorrect, there are differences between various USB
ports and how they provide power for charging. It's actually a very complex
subject but the gist of it is that any particular USB port has a maximum
amperage that you can draw from it for charging. This can range from as little
as 50 mA up to 2100 mA. What sets this limit is the maximum available to the USB
port itself, the number and types of devices connected to it and and a
negotiation that happens when you plug it in. If you plug your phone into an
unpowered USB hub, you will likely get some something around 50 mA. This will
charge a high capacity battery very slowly. It's fine for my bluetooth headset
or powering a mouse but any modern phone will have issues with it. In fact an
iPhone will say that it cannot charge from such a USB port but it will actually
charge, just very slowly.

Even with all of this complexity, no matter what it's plugged into and how long
it takes to charge, when your iPhone says it's fully charged, it's fully
charged... except when it lies to you. Yes, the iPhone will lie to you about it
how full the charge is. (I think that newer Android phones do too) When it
reaches 100%, it's actually somewhat less (maybe around 95%) and will continue
to charge although the number won't increase past 100%. What this does is it
allows your phone to run for quite a bit of time and still be at 100%. That
makes Apple look good that it has a phone that uses such little battery. Also,
modern phones do some power cycling while plugged in and at 100%. They will let
the battery drain a bit and then charge back up. This helps with the health of
the battery but they don't want you to see your phone at 95% if it happens to be
at the bottom of the cycle after being plugged in all night!

You will also find some differences between how laptop USB ports work for
charging. An older PC would supply 250 mA on a USB port and when you put the
laptop to sleep, that port would be shut off so you had to keep the computer
awake to charge a device. My 7 year old Dell laptop does this. When the iPhone
came out, Apple changed their USB ports to allow them to deliver more than the
standard maximum of 250 mA so that it could charge the iPhone faster than other
PCs could. They also would leave the USB port on if you put the computer to
sleep while the phone was plugged into it. Most PC laptops have adopted this
feature although some have designated a specific port that will be left on and
if you plug into a different one, it won't charge while sleeping. My 2 year old
HP laptop is like this.

One thing to be sure of, the wall charger that came with your device will likely
charge your device at it's fastest rate and often faster than a laptop. One
interesting thing that we found was that an iPad wall charger would charge our
iPhones at a faster rate than the wall charger that came with the iPhone.

I haven't looked into the USB3 specs but I wouldn't be surprised if they have
added these non-standard, high current draw, power features to USB3.



DIY Inertial Navigation?
(posted on 13 Apr 2013)

I have been fascinated by the developing field of small, semi-autonomous DIY
devices. I have an AR.Drone that, while being nominally remote-controlled, is
able to maintain a stable altitude and position, even in light winds with no
user input. It is really a user-directed autopilot.

One problem I have noticed with these systems is that they have limited ability
to understand where they are and how external forces (and even their own motors)
may change their location. Given the scale of these devices (less than a meter
in any direction), it would be nice for the device to know where it is, down to
an accuracy of centimeters.

My AR.Drone uses a combination of sonar to measure distance above the ground and
a downward-facing camera to see small horizontal movements. This allows it to be
amazingly accurate at maintaining a position as long as you stay within about 5
meters off the ground. Above 5 meters, it has a much harder time maintaining a
consistent altitude and has a habit of quickly taking off into the sky once you
reach the limits of sonar. Also, once you start to move, the horizontal location
information is lost.

Adding GPS won’t help much because horizontal accuracy is unlikely to be better
than 20 meters and vertical accuracy is even worse. (My bicycle rides often seem
to be substantially under sea level, according to the GPS on my phone). GPS is
great at generally locating where a device is. But, high precision is difficult
and expensive to accomplish. Phones have very tiny accelerometers and
magnetometers but just like GPS, these seem to be only useful for gross
movements and are not very accurate.

What's needed to bridge the gap between GPS and sonar/visual cues is inertial
navigation. This uses highly accurate linear and angular accelerometers in an
integrative way to determine a position based on a previously known position.
Before GPS, this was one of the ways that guidance systems were designed. Even
now, many military systems still use inertial navigation, at least as a
fallback, just in case GPS is unavailable. The problem has been that such
systems have been large and heavy. It was very interesting to see this Wired
article about the development of highly accurate but very tiny sensors that
should allow for wider adoption of much more accurate inertial guidance in
devices.

This will help build DIY autonomous devices that will be fun to work with. But,
it has some other applications that I think are interesting, too. Incorporation
of such a device will help create a much better record of my bicycle rides.
While my ride distances are reasonably accurate, climbing and descending hills
are not reported very accurately. This new technology could record these changes
in elevation much more accurately and thus give a much better picture of energy
use on a ride. Inertial navigation would be great for smartphone apps that keep
track of where you are. There are lots of places in cities and even outdoors in
more northerly mountainous or heavily treed areas where GPS signals are
unavailable. Inertial navigation would help fill in the gaps and even provide
higher accuracy. It would sometimes be great for my phone to know that I’m on
the 12th floor, near the north side of the elevators of an office building.

Reaction to Demise of Google Reader Shows Value of RSS
(posted on 7 Apr 2013)

In recent years, RSS seemed to have become stale, with little new developments
around it. It’s been available on just about every blog and there seem to have
been considerable consolidation around Google Reader as a consumption platform.
There have been a few other tools, like FlipBoard that have done a good job of
presenting data from RSS feeds into their systems. Even so, there has been
little news and little that is really new around RSS.

The problem with RSS has been that there has not been a very good
discover-and-follow mechanism that allows people to easily find and then start
following the content from an RSS feed. There have been RSS feed icons and
various buttons and tools that people have added to their blog so that you can
easily follow that particular RSS feed using a specific tool or platform but
nothing that is truly open and works with all platforms and is one-click
easy-to-use. It has been so easy to Friend, Like, Follow or +1 things with newer
tools that RSS has really taken a back seat.

Google’s announcement that they will shut down Google Reader on July 1, 2013 and
the firestorm that followed shows us two things:

 1. Google is following the trend to leave behind the open web in favour of
    controlled information silos.
 2. Many people are resistant to this trend.

This suggests that there is an opening to push for more open, federated systems
for distributing information. Maybe with some updated or new protocols to better
compete with the silos that Google, Facebook, Twitter, etc. are trying to force
us into.

Where Have All the Open Technology Companies Gone?!
(posted on 2 Apr 2013)

I find it disconcerting how often I see yet another tech company creating a
walled-garden, lock-in or a vertically integrated system that provides very
little benefit to the Internet as a whole. They stand on the shoulders of many
amazing people who selflessly provided groundbreaking technology for all to use.
These new companies don't "pay it forward"; they merely look to extract value
out of those earlier works.

The unfortunate thing is that by taking such a selfish approach, these new
companies are likely hurting themselves as much as they are depriving the world
of useful technology. Even in a company as successful as Twitter, I see that by
initially keeping a strangle hold on the network and eventually stomping on the
ecosystem developers built, and which ultimately helped them succeed, Twitter
has severely limited the possibilities that their network might have developed
into. I saw where Twitter was going when I developed Twemes.com in 2008 and
ended up abandoning any further work in that ecosystem because I saw it as being
a losing battle.

Truly groundbreaking and open technologies layered on the bedrock of the
Internet have slowed to a trickle. The only real successes in recent times have
been RSS and OAuth. The giant tech companies are trying to bury RSS. And, OAuth
is still a limited, fledgling technology.

I hope to write more in this blog about some of the ideas that have been
rattling around in my head for the last decade or so, specifically my ideas
around adding a layer of Internet infrastructure that can help raise the lowest
common denominator and that the next generation of technologies can be built on.

Electronic Archaeology
(posted on 21 Dec 2012)

I spent some time this morning going through the software on a computer running
Windows XP that has been a workhorse in my office for about 7 years since XP was
last installed on it. It was an interesting exercise in electronic archaeology.
There was software that I wrote many years ago on this machine. There were also
IM clients like Pidgin and IM services from Microsoft, Yahoo and AOL. Remember
those? There was lots of software on that computer that I couldn't even
identify. I'm sure I installed it at some time but I couldn't even figure out
what it was for now.

Over time, I have refined the software that I install on a new computer to the
point where it is basically a bunch of web browsers, a programmers text editor
and a web server and a software version control system. Everything else lives
out on the cloud. My 60GB of music now lives on Google's servers. I backup my
photos using Google and CrashPlan. I drag around a 25 year history of documents
from machine to machine but that is now a 30 second copy process and CrashPlan
keeps them safe. New documents, as rare as they are now, are created on Google
Drive.

It seems to me that I will not likely buy/build another new desktop computer.
Even a 7 year old machine is still "fast enough" for most of today's cloud based
usage scenarios. I have several such machines sitting around that I will reuse
when needed. I get a fresh computer ready for someone and get back their tired,
virus ridden machine in return. With a little effort, that computer becomes the
next fresh machine for the next person. Maybe I will upgrade the RAM or a hard
drive and put a newer operating system on but they are still quite usable for
Internet use or as a media device.

For the first time in my life, I have found that a laptop computer is mostly
sufficient for my day to day work. I still feel more productive when it is
integrated into my 7 screen setup in my office but I am surprised how much work
I can get done anywhere with just the laptop and an Internet connection. I can
even see myself going from a 7 pound luggable laptop to an ultra portable
computer or even a tablet with keyboard although I don't thing that iOS or
Android will cut it. I still need multiple windows open and lots of software
running. Most importantly, I need good cut and paste.

We've come a long ways from the days when I used a 28 pound luggable Osborne 1
