Speeding up Ethereum-Wallet initial sync on MacOS X

After experimenting with the Ethereum Wallet client on a linux machine I decided to install on my MacPro with OS X 10.11.5.  I installed the latest Ethereum-Wallet 0.8.1 app from github and launched the app.  I soon noticed that the sync would appear to freeze at various points and never achieved a full sync. This despite multiple force quits and restarts.

Close, but never closer!

After some poking around I found a nice summary of the problem and a workaround I wanted to share.

That reminds me: dump Java.

I was just reading a post at MalwareBytes Labs titled Cross-platform Malware Adwind Infects Mac by Thomas Reed about the Adwind Remore Access Tool (RAT) which reminded me I had wanted to remove JAVA from my Mac as it represents a security risk.  A quick DuckDuckGo search led me to How to uninstall Java in Mac OS X at dotTech which offered concise instructions for how to remove both the runtime and the jdk.

Go ahead. Do it. You’ll feel smart after using the Terminal.

Crazy (teen) driving makes THEM safer

I’m spending this weekend with my teenage son at the BWM Teen Driving School in South Carolina. The course is geared specifically for teen drivers and spends time on driving safety and theory, but mainly lets them do seemingly crazy things in powerful BMWs under the watchful eye of race car driver instructors (all the instructors here this weekend have won at least one championship).  But why would I, as a parent, want my son to do crazy things in (someone else’s) German sports car?  Let me explain.

BMW Teen Driving

We spend a lot of money on cars. We try to make sure they are safe, reliable, easy to drive, and that they have the latest safety technology.  What parent would put their child into a car without air bags and antilock brakes at the very least–be they a toddler or a teen? If financially possible, none of us would.  But how much do we spend on helping them become a better driver? And even if we do sign them up for a drivers’ safety program, its always safe and controlled and never approaches the limits of car control.  In teaching my son to drive I never encouraged him to “punch it,” or to brake as hard as possible at 45 miles per hour and steer around an obstacle, or drive faster and faster on a circle of wet road just to see what it feels like when the tires start to slip and how to regain control.

Car Lineup

When bad things happen during the course of normal day-to-day driving we are often thrust into situations where that is exactly where the car and driver find themselves–at the limits of car control. I don’t want that to be the time he discovers that the car will go where his eyes are focussed, so best be looking at where you want to go (escape) rather than where you don’t want to go (tree). Or that the brake pedal will chatter when breaking hard and that’s what’s supposed to happen (so don’t let up). Or that you can still steer the car when braking hard due to vehicle stability control. Or that if you run a wheel off the road, don’t panic and turn the wheel hard left to get back on.

Considering how expensive it is to buy that car, insure it, pay deductibles in accidents, and possibly have to be carried away from one, this is the best investment I’ve made in a long, long time.
