Business - Justin Foell

Mid-December I started to get a tickle in my throat. I knew the score. I only get sick about once a year, and this was going to be it. I took some precautionary measures – homeopathic meds that included vitamin C and zinc. I worked half days. Then it came on strong. With a fever of 102 I decided it was time to visit the doctor to see what I had gotten myself into.

Influenza A – the “bad” flu. Its subtypes include all these terrible sounding viruses: Swine Flu, Bird Flu, and H1N1. The doctor informed me that I was the first recorded case of the season at the clinic. Patient Zero.

I was supposed to attend a work conference that weekend. My doctor advised me not to travel, but I did anyway. My flight was non-refundable and my mother-in-law would be meeting us because we were bringing the baby. It was the baby’s first airplane trip.

Sitting in my hotel room I realized how stupid it was for me to travel. I’m an active vector for a potentially deadly virus. My largest fear was that my daughter would contract the virus and complications would arise. The doctor had foreseen this, so my infant daughter was on preventative medication. Then there’s my mother-in-law who would return to take care of her mother who has cancer. What if the virus spread? Infants and the elderly are the most vulnerable, especially if they have already compromised immune systems.

Shame. Guilt. NyQuil.

Viruses & Computer Viruses – strikingly similar

Most of the day in the hotel was spent reading Wikipedia about influenza and viruses in general. Viruses are terrifying. They aren’t really living things, described as “organisms at the edge of life”. They’re just microscopic particles of genetic code, waiting to use your body to perpetuate itself.

They have quite a bit in common with computer viruses. By itself, the virus can’t do anything. You usually have to do something stupid to contract a virus: re-using needles, unprotected sex, blindly running executable files from the internet. Then it spreads by seemingly harmless activity: touching, sneezing, connecting to the internet.

The virus needs you to do it’s thing. It needs action to be contracted, it needs your cells to reproduce, it needs you to send it out to infect others. It takes over the cells it’s infected, and forces them to instead make more viruses. Your cells will keep making copies of the virus until it bursts open like a spider egg coming apart at the seams. The reason we get a cough, runny nose, and sore throat is because we breathed in the virus. It started attacking cells in our sinuses, then dripped down into our throat. Gross.

Does the flu vaccine work?

I’ll admit it, I was a skeptic of the flu vaccine. When I was a kid, I got one shot for the Measles and then I was set for life. Why do I have to get a flu vaccine every year? Obviously science isn’t working or it’s some sort of scam. Or is it?

Turns out that these little virus bastards are reproducing so fast that they’re mutating into new strains, which may be immune to the current vaccination. The World Health Organization has to constantly play a cat-and-mouse game to predict what strains are likely to outbreak in next year’s season so they can be included in the vaccine. When you get a shot, it’s not just for one strain, but 3 or 4 strains that include both Influenza A and B.

Even if they don’t predict spot-on, there’s a chance that your body will have produced some anti-bodies that are close enough to effectively fight whatever strain you come into contact with. So do yourself (and your family) a favor. Get a flu shot. I know I will be.

My favorite age for babies is 3-9 months. They can’t yet walk, so they’ll really only get into trouble with things in an arm’s reach. They (hopefully) sleep through the night. They can hold their head up, so I feel more comfortable man-handling them during diaper changes and play time. 3 months has also been the magic marker when my wife goes back to work. So whether I want to or not, that baby is going to be in my hands quite a bit more now.

Many have asked me how I get work done at home with the baby at home with me. For my part, I only work part-time. It would be near impossible to work a 40 hour week with a baby at home and still maintain a relationship with my wife.

For the baby’s end of the bargain, the key is sleep.

Continue reading →

Despite what many think, babies are actually pretty easy to care for. They really only need one of three things:

Food (breast milk or formula)
A diaper change
Sleep

And babies sleep a lot. At 3 months my daughter was taking 2-3 naps during the day. The key is to work during these times. If your baby has a somewhat regular napping schedule, you can even schedule home-office meetings or calls during these times.

Recognizing the signs

By 3 months you should have an idea of what your baby’s nap schedule is like. But there always is the element of recognizing the signs of sleepiness and acting quickly. The second my daughter rubs her eyes like this, it’s time for a nap:

Your baby will probably continue to rub her eyes, but if you miss these cues, it will be increasingly harder to get them to take a solid nap. She will become over-tired and fussy:

This likely means getting her to sleep might mean “rocking and holding” rather than the usual “place in crib quietly for a good nap.”

Sleep cycles

Humans sleep in cycles of around 90-100 minutes. You should be aware of what time your baby goes to sleep and what time she wakes to make sure she’s keeping to these cycles. Waking up outside of this schedule (like after 45 minutes), may mean that she’s waking up from a dream or is currently having a dream and may actually go back to sleep.

On a bad day if my baby takes two naps, that’s 3 hours of work I can get done during the day. On a “normal” day she’ll take a 1.5 hour nap and a 3 hour nap for 4.5 hours of work. Combined with a couple of evenings of work, I can pretty regularly get in 20-30 hours a week of work – but it definitely isn’t a regular 9-to-5 gig.

Embrace the (lack of) Schedule

I go with the flow and prepare myself mentally by thinking about what I’m going to work on while my baby is awake, so that when she goes to sleep I can dive right in. It’s amazing how far a little mental preparation can go when it’s time to actually work.

It may also mean that if baby naps 3 hours in the morning, you’re probably going to be working through the lunch hour. Go hungry, I promise you’ll live because if you take off time to eat now, you’ll be missing it later. Plus baby needs to eat when she wakes. You’ll have plenty of time for lunch then.

Don’t be that guy

I want to throw this out there, because I have been tempted to do this: try to work while my offspring are awake. I have never regretted forgoing a full-time job to work at home part-time with kids around. I have however, regretted trying to work while my kids are up and at-’em. Ignoring them is going to result in two things: they’re going to get hurt or into trouble, or they’re going to bother you until no end – possibly both. Either way, don’t be that guy. Interact with them when they’re awake, and work diligently while they’re asleep. You’ll both feel much better about this agreement.

This rule gets looser as kids get older but not by much. My son is content to play in his room sometimes by himself, but I make sure to stay within an earshot to make sure he’s not getting into trouble. I tend to use these times for what I call “light work” – usually stuff that is not time constrained – like email.

Reduction of naps

As your child ages into a toddler, their naps will reduce. Eventually they’ll be down to one nap a day, usually in the afternoon. My son (who also stayed at home with me as a baby) eventually would just take one nap in the afternoon at 1PM. As he got older, it increasingly went from a 3 hour nap to a 1.5 hour nap. With regular 3 hour naps, you can still get in 15 hours of work, plus evenings to get in 20 or so hours for the week.

When 1.5 hours of nap time per day becomes the norm, it’s time to consider daycare if you don’t want to offend your clients and co-workers. I was able to put my son in day care part-time (3 days a week). We still have some hang-out time, and I could get most of my work done on the days he’s gone. I suspect I’ll take the same route with my daughter.

I find it amusing that some of my cycling friends have just discovered Strava, right at a point when I’m looking to leave. When they ask why, I cite Strava’s recent decision to shutdown API access to all but a select few app vendors. I had an inkling why access to the new API was limited, and I’ve confirmed it. Now I’d like to explain the correct way to do it, and how to monetize it at the same time.

Continue reading →

Strava API the wrong way

I had a suspicion that no open source projects would be able to use the new Strava API, and I was right. All you have to do is read this one sentence at the top of the new V3 API documentation:

All developers need to register their application before getting started. A registered application will be assigned a Client ID and Client SECRET. The SECRET should never be shared.

This is a broken model. Essentially app developers need to get approved for access and then they’ll embed their OAuth secret in their code, which will be sent to Strava to authenticate before making any calls.

This. is. wrong.

Besides being a bad approach, it leaves out all open source applications because they can’t simply put that OAuth secret right in their code – it would be there for anyone to see (and use).

Strava API the right (Facebook/Twitter) way

Let’s take a look at how Facebook and Twitter handle app authorization. I know these guys aren’t exactly angels, but when it comes to web services API access, I think they have it right. When you use an open source application to connect to Facebook or Twitter, you as a user can set up and authorize an “app.” Think of an app in this case as more of an intermediary between you and Facebook / Twitter.

Here’s how it works: as an end-user, you set up an app on the Facebook or Twitter developer website. In exchange you get back the aforementioned Client ID and Client SECRET which are unique to you and the instance of your app. You put your Client ID and Client SECRET into your database (or wherever it goes) and since it is unique to you, it never needs to go anywhere in the code.

On Twitter the process can be almost fully automated and completed for you. You can have apps created and all you have to do is approve that they can access your Twitter stream, and then save the OAuth credentials it gives back.

This is a great model for open-source software. WordPress, software that powers over a billion websites, is open source, and you can install a plugin like Twitter Widget Pro which will display your Twitter stream on your website. This plugin automates as much as possible and walks you through the app setup and approval process.

To control (read: restrict) app access, Strava could easily add a 3rd identifier (I’ll call it App ID). Strava could have developers (not end-users) apply for an App ID. Based on their criteria, they could accept or reject those requests. The App ID could be public and exist in code – open source or not. Because you would need an approved App ID and a legitimate Client ID and Client SECRET to authenticate. Strava could block apps on occasion and still achieve widespread adoption.

Monetizing API Access

This is a no-brainer. If the system were re-worked to put the app and API access in the hands of users, Strava could simply make it only available to premium members. I’d gladly pay Strava $6 a month if they gave me back API access, plus it would help weed out anyone that would be abusing the system (although I’m still unclear on how someone would do that).

Also, you could still maintain the status-quo with the current V3 applications – they already have their Client ID and Client SECRET already set up.

← Summary Only

When I started writing regularly, I thought much of my content would relate to what it’s like working at home, part time, with kids at home. My oldest has been in daycare for the last two years, so it’s been easy-street as far as working from home is concerned. This changed recently when my daughter was born, and more importantly, when my wife returned to work. So it’s time to revisit what it’s like having a newborn at home.

I’ve discussed sleep deprivation before in regards to the 24hr Website Challenge. Sleep is an important thing to me and I can’t stress this enough: nothing can prepare you for the sleep deprivation you’ll experience with a newborn baby.

Prior experience not applicable

When I was a young man (age 18-21) I marched in a drum and bugle corps. I figured this experience would have me conditioned well enough to deal with a crying baby in the middle of the night. In drum corps, we’d travel via bus at night, after the previous days show. We’d typically arrive at our next destination sometime between 2 and 5AM. We’d all stumble off the bus like zombies, grab our sleeping bags, set up a place to sleep (usually on the gym floor of whatever school we were staying at), and then go back to sleep. If you were really fancy you took time to brush your teeth with running water, and blow up an air mattress.

This is not what it’s like with a newborn. In drum corps the only variable was when you were going to arrive. You controlled how quickly you could set up your bed and get back to sleep.

Enter the newborn

Babies don’t know or care that you have to get up at 6:30AM to get to work, or that you were up until midnight feeding them the night before. They just know when they’re hungry and will cry until they eat. They also eat at their own speed, need to be burped, and generally be content before everyone can go back to sleep.

If your wife is breastfeeding, most of the burden lies on her. But as a good husband, you should help her bear the burden by fetching a baby, burping her, and putting her back to bed.

I should note that I was much more helpful with the nighttime routine with our first child than with our second. Maybe it’s because I was younger, or more excited as a new dad. Whatever the case was, I’m certainly not going to try to take credit for everything my wife has done for our children during these early development stages. So whatever sleep deprivation boogey-man stories I’m telling, you can bet she’s experiencing it to a greater degree.

There has been occasions where I’d look over and see the baby on the boppy in front of my wife. The baby could be eating, but could be sleeping, and my wife definitely looks like she’s sleeping. I’d say, “put the baby to bed, you’re falling asleep!” But she was always quick to retort that she was just resting her eyes.

The deprivation also isn’t like what you might experience with a normal work or school week. Staying up late and getting up early, you just want to get to the weekend so you can sleep in. Do these babies know what day of the week it is? Heck no! My son is 4 years old and still has a hard time getting the days of the week, but he can read a digital clock and knows not to bug us before 8AM. So that’s the best you’re going to get on Saturday and Sunday: 8AM – minus all the times you got up in the middle of the night for your newborn.

Advice

If I were to give advice to breastfeeding mothers (which I’m not qualified to), it would be to nap when your baby does. This obviously only works when you’re on maternity leave and not operating a vehicle. Many busy mothers feel they need to get stuff done while their baby is sleeping. Do yourself a favor and get all that stuff done when you have nesting urges, before that baby is born, so you can nap yourself back to reality.

For those mothers and others (like me) who are also trying to get work done during this period, hopefully your work is flexible. Tell your coworkers about your situation – you did tell them you had a baby, didn’t you?!? Your ability to work will become sporadic, and spread out throughout the day. If you do technology work, buy yourself a laptop if you don’t have one so you can be mobile. Make sure it’s powerful enough to do everything you’d normally do. Even if it just means being able to work on the couch rather than in your office, it will help.

The good news is this situation is temporary. Once your baby sleeps through the night, you will be able to as well.

Garmin is the Apple iPod of GPS products. So when it came time to purchase a new GPS, I grabbed a Garmin eTrex Vista HCx. It had a great feature set for a handheld unit: SD card expansion, turn-by-turn directions, etc. And because it’s a Garmin, it had the best “hacker” support, namely: free maps from Open Street Maps.

The one thing that I was dissatisfied with was the software support under Linux. Sure you could plug it in, and retrieve data, but simple editing of tracks (splitting, joining) was tedious. Garmin’s free MapSource software worked well, but I wanted to avoid booting into Windows just to use it. Luckily I found this thread on ubuntuforums.org. I rehash here much of the info provided there, and include some updates.

An Aside about Strava

I use my GPS mostly while cycling. A while back a friend tipped me off to a site called Strava where you can track your rides and compete virtually with others.

I’m not a competitive cyclist. I ride more to shuttle kids to the library, or for picking up groceries. But I do like to use my GPS while riding and upload the data to Strava to track my miles, calories burned, etc. It’s also fun to see what sort of excruciating rides competitive cyclists are doing.

My beef with Strava is that they just recently shut down the version 1 & 2 API access to their site. They are launching a new V3 API, but your application must be approved to use the service. Unless a new version to any API is fully available, it’s customary to leave the old version(s) of the API accessible for a period of time so developers can update their software. Unless the old API is causing undue stress on server hardware and equipment, there should be no reason that an old API is turned off before the new one is available.

My guess is that they (like Twitter) want to control who can/can’t use their API. It could also be a stupid knee-jerk reaction, like I’ve seen many governments and businesses make. Recently there was a lawsuit brought against Strava. They may now want to control the exact wording of the competitive elements of the apps so Strava users aren’t feeling coerced into regaining their top time by riding dangerously. It all feels like a digital nanny-state to me. My guess is that no open-source projects will be able to use the V3 API because there’s probably some DRM key (or equivalent) required to connect.

Nevermind that I’m a contributor to the Strava plugin for WordPress (which no longer works thanks to Strava). WordPress only powers a billion websites and has the largest market share of any web publishing platform. Isn’t the point of having an API to promote the widest adoption possible?!? If Strava doesn’t change, maybe I can convince tons of WordPress cyclists to switch to Garmin Connect – they don’t seem to be ostracizing developers.

Back to installing MapSource…

Installing Wine

The first order of business is installing Wine:

sudo apt-get install wine

Then run winecfg (as your normal user). This will create a ~/.wine directory:

winecfg

Just click OK when the dialog appears.

Installing MapSource

In order to install the latest MapSource, you actually have to install an older version of the software first because MapSource checks for the presence of an earlier version during installation. Fooling the earlier versions to the presence of MapSource is actually quite easy:

cd ~/.wine/drive_c
mkdir Garmin
touch Garmin/MapSource.exe

Get an older version, like MapSource_6153.exe from http://gawisp.com/perry/mapsource/

Then run the installer:

wine ~/Downloads/MapSource_6153.exe

Follow the on screen instructions. Accept the license and it will install. At the end of the install you can launch MapSource – don’t do this! Uncheck the check mark and just exit the installation.

Once you’ve installed MapSource the simple way, you can then update to a newer version of MapSource which looks for a “proper” MapSource installation. There may be some sort of secret sauce to having your upgraded MapSource fully functional. I initially had problems with the newest version crashing when saving a GPX file. But then it went away when I did a couple of incremental upgrades. If you have this problem, maybe try removing the latest version through the Wine uninstaller and installing a slightly earlier version. Please comment if you have any insight as to what works and what doesn’t.

Add Maps

Adding a drive

My maps exist on a Windows partition on my computer. Rather than reinstalling the (huge) files in Wine, I added a Wine system drive that linked to my Windows partition.

After mounting the Windows partition (simply by selecting it under devices in the nautilus file manager), I then made a symlink to my ~/.wine/dosdevices/ folder:

cd ~/.wine/dosdevices
ln -s /media/justin/OS "o:"

Replace /media/justin/OS with the correct path to your Windows partition, once it’s mounted in Linux. I chose “O” as my drive letter since I normally mount the disk as “OS” – you can choose whatever drive letter you’d like.

Add registry keys

This is most easily done by exporting registry keys from Windows and importing them into Wine’s registry. Here is a screenshot from my registry from Windows:

In the UbuntuForums post, the author notes that MapSource looks for maps under HKEY_LOCAL_MACHINE\Software\Garmin\MapSource\Families, where as my installation (Windows 7) had the maps installed under HKEY_LOCAL_MACHINE\Software\Wow6432Node\Garmin\MapSource\Families. So I exported the keys from Families in my Windows installation and then installed them in the same place in the Wine registry.

wine ~/.wine/drive_c/windows/regedit.exe

After installing the key(s) into the Wine registry, I updated the values and changed any references to C:\ to O:\ – my custom Wine device that links to my Windows partition.

Once this is done you can test that your maps are being read correctly.

cd ~/.wine/drive_c/Garmin/
wine ./MapSource.exe

If your maps are installed correctly, they’ll show up under View > Switch to Product. Even if you have no maps installed, MapSource may still be useful to you for downloading tracks from your Garmin and exporting to other formats such as GPX.

Set up a COM device

In order for MapSource to be able to upload/download anything from your GPS, we need to set up a COM device so they can communicate. First load the garmin_gps kernel module (which strangely didn’t autoload in Ubuntu):

sudo modprobe garmin_gps
lsmod | grep garmin

And you should see something like:

garmin_gps 18212 0
usbserial 36911 1 garmin_gps

Turn on the GPS and connect it to the USB port. Then do:

ls /dev/ttyUSB*

You should see a device called ttyUSB0

Now we have to make this device visible as com1 port under Wine:

cd ~/.wine/dosdevices
ln -s /dev/ttyUSB0 com1

When you want to transfer data from your GPS, plug in your Garmin, then run:

sudo modprobe garmin_gps
cd ~/.wine/drive_c/Garmin
wine ./MapSource.exe

In the Transfer menu, select Receive From Device. You should now see your device and can transfer tracks, waypoints from your GPS into MapSource.
