Family Computers, 2016 edition

As the summer of 2016 draws to an end, it's time to plan my family's IT setup for the 2016-2017 school year.

My current setup


Phones for kids

The big change this year was that my youngest kids got their own phones. The process went well. I'm glad I spent the extra money to buy refurbished iPhone 5s's instead of cheaper phones. The iPhone 5s's have been reliable and easy to administer. The 16 GB of storage has occasionally been a problem.

I restrict my youngest kids' phones so that they can't install apps. It's tedious to have to unlock and then relock the phones to install apps for them, but I like being able to have a say on which apps they have on their phones.

I bought Otterbox cases, which worked well at protecting the phones. So far all the phones have survived. One phone did get dropped in the water briefly, but it worked OK after it dried out.

The T-Mobile Simple Choice plan has worked well for us. It has a 1 GB/month data cap per line. When you exceed the cap you still get data, but at a low speed.

A nice bonus: T-Mobile gave everyone unlimited high-speed data for 3 months last year. I believe the kids used an average of 2.4 GB per month while that was available. But they seem mostly happy with the 1GB / month limit.

Laptops work great

The Macbooks have been great. They're used for web access and light content creation.

Declining desktop usage

Our computer usage has shifted to laptops. Our desktop Mac mini computer goes weeks between uses, and I notice that I seem to be the only one logging into it these days.

Modest tablet usage

Our two tablets get relatively little usage. The mini is used for puzzle games, the Pro is used for comic book reading, video watching, and drawing/animation programs.

This is partially a "personal vs. shared" issue. People prefer their personal phone and/or laptop to shared tablet.

It's also a "tool at hand" issue. I find myself using a laptop or phone rather than a tablet just because the laptop or phone is always closer to hand.

Minimal Apple TV usage

Our Apple TV gets almost no usage. Its controller sucks for games, and family members prefer to watch video on their personal laptop or phone.

Our family TV is used mostly by my wife who still likes watching broadcast TV in the evenings.

What didn't go according to plan

Apple's hardware releases modified last year's plan:
  • I dropped the Android TV in favor of the latest Apple TV. The Apple TV works great, but it turns out that we don't use it much.
  • I exchanged my iPad Air 2 for an iPad Pro. Love the keyboard and stylus.

Beats headphones are low quality

I spent a lot of time this year dealing with broken headphones. My daughter's Beats wired headphones failed twice while under warranty. Apple was nice enough to replace them (with refurbished headphones) each time, but it required two trips to the Apple Store for each incident.

Getting rid of old electronics

For what it's worth, Amazon has a good trade-in service that buys old electronics for a fair price. Not as good a price as you'd get on Swappa or craigslist, but zero hassle. I used it to get rid of a bunch of old consumer electronics gear that I'd accumulated over the years.

Best hardware purchases

  • Phone holders for the cars.
  • Multi-port USB chargers for car.
  • Multi-port USB chargers for bedside.
  • Short (4 inch) USB cables for bedside charging.
  • Long (10 foot) USB cables for car and couch.
  • External battery packs for recharging phones.

Plans for 2016-2017

  • Keep current phones & laptops.
    • I will upgrade to the latest iPhone just because I need it for my work.
  • A Sony Playstation 4 NEO.
    • My son is desperate to play the latest video games.
  • Support school-issued Windows laptops.

Keeping current hardware

I'm happy with my current hardware. The equipment is reliable and easy to administer. There doesn't seem to be anything significantly better on the market or on the horizon.

My kids report that the iPhone 5s is the current "standard" phone model among their classmates. (6th grade and 8th grade). So at the moment there isn't any social pressure to upgrade. My son would like a larger screen and a bigger battery. I got him an external battery pack, we'll see if that helps.

Apple is rumored to be introducing new Mac hardware this year, but based on rumors it doesn't seem to be significantly better for our budget and use cases than our current hardware.

Consoles vs PC gaming

My son's grown out of Minecraft, and now wants to play teen games.

In the past few years Macs have stopped being able to run modern games. mostly due to Apple not supporting recent 3D graphics APIs.

High-end gaming PCs work well for games, but they're expensive to buy and maintain.

A console seems like the best choice for us. Based on performance and exclusives I'm leaning towards the Sony Playstation 4. A new version of the PS4 is rumored to be coming out in October. I'll probably get that.

Return of Windows devices

The big change to my home network this year will be dealing with school-issued Windows laptops. I want to keep the Windows devices off my home network, but I also want to give them access to the Internet and to a local printer. I think the simplest way to do this is to buy a new Wi-Fi printer, and put the laptops and printer on a guest network.

I could get a fancy router and set up multiple virtual networks, but buying a second printer seems simpler. Perhaps if the second printer supports cloud printing I can use it from all my devices, and then retire my current printer.

I think the whole idea of a local network is becoming obsolete. In many cases it's simpler to assume that every device is always on the public internet, and just configure the device to survive in that environment. The only devices in my house that really need to be behind a firewall are the printer and the NAS.

Slimming down

If anything, I might simplify my home network by retiring the desktop computer and the NAS. 



In the past I used the NAS for storing backups and downloaded videos. But these days I use cloud services for both backups and videos. I rarely use the NAS.

I rarely use my scooter computer. It was educational to set it up, but I don't really use it.


Two thumbs up for DigiPen ProjectFun

I sent my kids to the DigiPen ProjectFun summer camp this year.

It's expensive ($1400 for 10 days). It is very well run. My kids loved the experience, and they learned a lot about the topics (animation and game programming) they took.

The classes were structured as 7 days of instruction, 2-and-one-half days of final project, and then a demonstration on the afternoon of the last day.

FWIW I am well versed in both animation and game programming. I've tried to teach my kids these subject. They learned more from these courses than when I tried to teach them at home.

The instructors emailed me a detailed "what we did in class today" letter every day. I found it helpful to read the letter and use it to prompt discussion with my kids.

A nice side benefit is that my kids were exposed to relatable role models in the game industry, through the many DigiPen students who are helping run the camp. "Dad, everybody has nose rings."

Only drawback: my kids now think less of my old games: "Dad, no offense, but your [1980's vintage 8-bit era] game is kind of lame."

I think this camp would be best for 5th-thru-10th graders. For a self-motivated older child it might be better to spend the money on computer hardware, software and books.

Scanning old documents

That which is resisted, persists.
I'm going paperless in my home office. Over my 30+ years of adulthood I have accumulated 20+ filing cabinet drawers of paper records. Plus there's a ton of unsorted bills and junk mail piled up.

My strategy is to tackle the filing cabinets first, then work on the unsorted bills and junk mail. My reasoning is that doing the filing cabinets first will help me set up my taxonomy on Google Docs, making it easier to file the new documents later.

My strategy for scanning my filing cabinets is:
  • Go through each file cabinet drawer and storage box, one at a time.
  • Sort docs into 3 categories: scan & keep, scan & shred, shred.
  • Scan documents to PDF files with a Fuji ScanSnap ix500.
  • Store the scanned documents in folders (with the same name as the original folders) on Google Docs.
  • Put the "keep" documents back into the same folder and cabinet drawer that they came from.
  • Make a backup copy of the scanned documents to a USB stick.
My strategy for deciding what physical items to keep is:
  • Keep official government documents like tax returns forever.
  • Keep items related to tax returns for 15 years.
I've scanned one half drawer so far. It takes a while to scan old documents. Lots of staples to remove.

At this rate it's going to take about six months to scan everything. Yow!

2015 Year in Review

Here's my take on tech trends in 2015 and predictions for 2016.

Personal trends in 2015.
  • I started using Twitter, following a mix of optimistic tech bloggers, economists and comic-book artists. Always something interesting to read. I don't tweet much. (Nothing to say :-P)
  • Podcasts. I'm following a bunch of tech, gamer, and comedy podcasts. I especially like The Voicemail, Accidental Tech Podcast, Melton, and Guys we F*cked (NSFW) .
  • I switched to a large-sized iPhone 6s+. The big screen is great.
  • I stopped maintaining my "Terminal Emulator for Android" program, because I lost interest in the idea of an on-device terminal emulator for Android. (And I lost interest in maintaining the project in the face of frequent Android UX and build system churn.)

Open Source

I've been doing less open-source software work than in previous years. My OSS work has been driven by emotion and "hack value". This year I haven't come up with any ideas that were exciting enough to work on. Partly this is because we're in the midst of a change from PCs to mobile, and it's not clear to me what needs to be done in the new mobile-first world. And partly it's because things are working pretty well. I feel that I have my basic computing needs taken care of by existing apps.

More than once this year, I came up with an idea for a project, only to find a perfectly serviceable implementation already available for free or only a few dollars. Each time I installed the existing app rather than writing my own version.

Video Games

I found myself playing fewer video games. I bought lots of mobile games, but mostly for my family rather than for myself. My wife briefly held the world record high score for the puzzle game Spl-t.

I'm still waiting for The Witness and The Last Guardian to ship. I may buy a PS4 to play TLG. Or I may just watch the inevitable "Let's Play" walkthroughs. It seems like the kind of game that would be almost as much fun to watch someone else play as to play myself.

Hardware

I bought an Apple TV 4th Gen and an Apple iPad Pro. I'm using both primarily for media consumption, although once I obtain an Apple Pencil I hope to use the iPad Pro for some sketching.

I had hoped to write games for the Apple TV, but the bundled controller is too limited to support interesting games. And the development model is clunky, requiring either two Apple TV units, or a long cable. I think it makes more sense to concentrate on iPhone/iPad apps than Apple TV apps.

Computer Languages

I'm studying Swift, trying to decide if it's good or not. It's a positive sign that Apple open sourced it. I like the "Playground" feature.

I wish I could use Go more, but I don't currently have a project for which Go is suitable.

Similarly, I'm impressed by recent developments in Clojurescript. I wish I had a project idea for which Clojurescript was suitable.

2016 Trends

  • Mobile
  • VR
  • Machine Learning

Family IT Information, end-of-year edition

Just an update on my family IT use.

The T-Mobile family plan has worked great for us. T-Mobile's plans are nice for us because:
  • The third, fourth, and fifth lines are only $10 / month.
  • When the paid-for data is exhausted, the plans automatically switch over to unlimited free low-speed data for the rest of the month.
  • Streaming music doesn't count against the data caps.
  • Free phone calls, texts, and low-speed data in Canada and Taiwan. (It was great using Google Maps to get around Vancouver. I was using many short cuts that I didn't know about when I was navigating using paper maps.)
  • For the last 3 months of 2015 T-Mobile had a special where they gave everyone unlimited high-speed data for free.
I ended up getting used iPhone 5s's for all my kids. I had the kids pick their own otterbox commuter cases. 

My son was initially frustrated at having to give up his rooted and customized Android phone for the smaller, less customizable iPhone. He's grown used to it, and likes it now. Everyone loves the fingerprint unlocking feature of the 5s.

I have the phones set up with restrictions, so that the kids can't install their own apps. I also confiscate-and-recharge their phones and laptops each night. This is fairly foolproof, and gives the kids 8 hours a day to sleep without electronic distractions.

I bought an Anker 6-port USB charger for my bedside table. I use it to recharge everyone's phones while keeping an eye on them. I have the phones on "Do Not Disturb" mode, so they don't bother me over night.

The "Find my Friends" app has proved helpful for keeping track of where everyone is, especially for things like picking kids up at school and at bus stops.

We now have 5 laptops: four 13" Macbook Airs and one 13" Macbook Pro. They work great and last a long time. They are mostly used for web surfing, YouTube and Minecraft.

We have had problems with headphones -- the kids are rough on headphone cables. They've already gone through one set of headphones each. Currently we're using Beats headphones due to them being relatively cheap on sale and/or included in Apple Educational bundles. They look stylish and work OK. Apple has a fairly good warranty repair process for their Beats headphones.

Happiest recent purchases

A few products that made my summer family travels happier:


Anker 4-port USB car cigaret lighter charger.

Car vent phone holder (don't remember the brand.)

Short stereo audio cable. It's ghetto compared to bluetooth, but more reliable.

Family Computers, 2015 edition

As summer draws to a close, I am planning my family's computer use for the 2015-2016 school year.

My plans for this year are:
  • Each family member gets their own mobile phone and laptop.
  • We also have a shared desktop and a few shared tablets.
  • Shared network scanner/laser printer.
  • We print color documents and pictures at the library or at the drugstore.
  • Android TV for shared movie watching.
  • Chromecast for audio sharing.
  • Comcast Business Internet
  • Apple Time Capsule for backup / WiFi / NAT
Note the lack of a dedicated game console. The kids play games on mobile, tablets, and laptops (for Minecraft specifically!).

My two youngest kids are getting their first phones this year. I'm worried about their phones getting lost, broken, or stolen. So for the first six months my kids will use hand-me-down phones. After they've learned to take care of phones, I'm going to give them better phones. (Still used, though!)

To achieve my plan I need to buy one laptop and three mobile phones. For the laptop I'm leaning towards a 13" Retina Macbook Pro. For the phones I'm leaning towards used iPhone 5Ss.

Why a Macbook and not a Chromebook? Build quality and applications. I have a low-end ARM Chromebook, and I noticed that nobody in the family uses it by choice, due to its low speed and poor quality screen. I _could_ get a Chromebook Pixel, but for my family, at that price level a Macbook is a better deal.

Why iOS and not Android? It comes down to ease-of-administration. I want to lock down my kids' phones, and unfortunately experience with my oldest child using Android is that it's all-too-easy for him to defeat the aftermarket Android parental control apps.

For phone service I'm probably going to go with the BYOD T-Mobile Family Plan, because:
  • It is cheap.
  • Unmetered music streaming.
  • When you hit your data cap it switches to low speed data for the rest of the month, rather than charging more.
  • It has free 2G international roaming.

Thoughts on laptops and other legacy hardware

If I were on a tighter budget, or starting from scratch, I'd consider dropping the laptops, the Comcast Internet, and the home WiFi, and going pure mobile. I would get bluetooth keyboards to make typing school assignments easier.
