The Modern Family's Guide to Technology to take on a European Vacation

Image
This summer I took my Seattle-based family of five for a three-week trip to Europe. We had been promising the trip to our kids since they were little, and this year we were finally able to go. We had a wonderful time!


Here are my tech-related traveling tips.

Hardware Tips Take your mobile phones Take one modern mobile phone per person. Android, iPhone, either is fine, but you'll want something with a SIM slot and nice camera.
Leave your laptops at home I didn't take any laptops with me, and I was able to do everything I needed to do using just my mobile phone. It was a relief to not have to lug around a laptop.
A few times I had to request the desktop version of a web site, but for the most part, the mobile phone worked fine for…

Family Computers, 2017 Edition

A quick update on my family's computers, as we start the 2017-2018 school year

I love them. They have worked flawlessly since the day I plugged them in. Best Google hardware product ever!
Phones I upgraded my kids to refurbished iPhone 6s+s in Incipio cases. They are happy campers. We kept their old iPhone 5s's as backup phones for science projects and vacation trips.
No more Beats headphones I've been having problems with my kids' Beats headphones. I had two sets of headphones, and they both needed to be repaired twice while under warrantee. When they broke again after the warrantee had expired, I just threw them away.
I now buy my kids $15 Panasonic earbuds. They don'…

Team Blue Iris ICFP 2017 Programming Contest Postmortem

Team Blue Iris ICFP 2017 Programming Contest Postmortem My son and I competed as team "Blue Iris" in the ICFP 2017 programming contest.

The ICFP programming contest is an annual 3-day programming contest sponsored by the International Conference on Functional Programming. Functional programming is an approach to writing programs that stresses writing as much of the program as possible in terms of functions. That's as opposed to the more commonly used imperative programming.

In the contest, people form teams to compete for three days to solve a problem, using any combination of programming languages. People compete for the joy of problem solving in the language of their choice. It's common for people to use outlandish or obscure programming languages. It's sort of like the Wacky Races of programming contests.



I've competed in this contest about six times over the past 10 years. This year was the first year my son joined me. My son's got about a year's …

On-the-cheap Machine Learning computer

I recently put together a cheap-and-cheerful machine-learning-capable PC.

https://pcpartpicker.com/list/wwyQ2R

Highlights are:
Pentium G4560 CPUNVIDIA 1060 6GB GPU16 GB RAM512 GB SSD The main difference from a budget gaming rig is that I chose a relatively overpowered GPU. This is because for machine learning I think the main bottleneck will be GPU RAM size. This particular GPU model has a lot of RAM (6GB) for a relatively low price.
The other extravagance is the 512 GB SSD. It would have been cheaper to use a smaller SSD coupled with a traditional hard drive. I went with a single SSD because I don't want to deal with the hard drive.
So far my son's done far more gaming than I've done machine learning. He likes the system a lot. It's >10x the graphics performance of his previous machine, a 2012 Mac Mini running Windows 10 in Bootcamp.
