Living la vida Linux

This morning, I finally broke down and installed Ubuntu 15.10 into Virtual Box. I didn’t take notes, which I am now kicking myself for because it didn’t occur to me until after I had gone through the entire annoyingly tweaky process.

Here are the highlights.

First, I installed Virtual Box. I mostly went with the directions in this Simple Help write-up. The directions are 15.04, but they worked fine for 15.10. Per the write-up, I went with all the defaults. It took an hour or more for the Ubuntu install to get itself set-up. Prepare to head out for a few errands.

Next, I spent time familiarizing myself with Ubuntu, finding the terminal, chsh’ing to tcsh from bash (I had to apt-get tcsh) and setting up my .cshrc. I also installed lns (bless it) and downloaded the latest 15.10 Swift 2.2 snapshot from swift.org.

Then I symbolic linked swift and swiftc into my ~/bin folder, checked that I could run them both from wherever, and then set to working on getting ssh running so I didn’t have to use Virtual Box directly.

To do that, first I had to apt-get install OpenSSH-server, which was no big deal, and then what took the most time was figuring out how to set up networking. Turns out that you need to shut down the machine, set up Adapter 1 to use Bridged Adapter (thanks aciidb) and the find the 10.0.whatever-ip-address using if-config after rebooting. (Mine was 10.0.0.35).

Once I got past that, I was able to ssh in over from my Mac and start using Swift. I began with a simple shell script (thought that was easier) and then moved onto swift and then swiftc compilation.

As Mike Ash pointed out, when encouraging me to use ssh with Virtual Box, you gain all the utility of your normal terminal session including copy, paste, etc without having to deal with mouse capture, etc.

Hardware hacking help solicited: Remake my stroller

Photo 12-10-2015-11.12.49

This is my Jeep stroller. It is probably the best stroller ever. It’s also the best shopping cart ever.  It has cupholders. It has not just a pop-up glove compartment at the top but extra cargo bags on the left and right for small items.

The basket underneath is enormous. It carries tons of weight. The wheels are rugged and have been able to navigate through just about any terrain, including going to the local market through Colorado winters.

I can load a couple of 12-packs of sodas, carry about 6-8 other bags of groceries. There’s room above, there’s room below, there’s easy-to-tie-to-handles. When I’m at the store, I can stick a basket in it, fill it, surround it, and put coats, gloves,  hats, etc below (or use that area for more groceries). It is, in short, the ultimate shopping machine.

Only one problem. My baby is now a few years away from starting to grow facial hair. Try to use this thing and you get side eye, hairy eyeball, every kind of “are you some kind of sick bag-lady with an old shopping cart stroller” look you can imagine.

There’s some kind of unspoken consensus that after our kids have grown, we must transition to granny carts. I used to own a granny cart when I was in college. It was fantastic. (4-wheel variety because two wheels and tilts are a sucker’s game.) I loved that cart for shopping, laundry, and so forth, but after using my Jeep stroller, there is no way I am going back to the granny cart.

I’m throwing this out there to my brain trust. How do I “de-baby” this cart so I can continue using it to lug massive quantities of various haulage without being a social pariah?

It was bad enough a few years ago when I could answer all the “so where’s your…baby…?” questions with “I’m on the way to pick him up from daycare/school/whatever.” But now? I don’t have that excuse.

There is no baby. There is only cart. It doesn’t have to be “cool”. I just don’t want members of the homeowners association to start calling the police about the crazy lady walking around with an empty baby stroller.

Thanks in advance for your help.

Swift: How to find undocumented functions

In response to requests for more clarity. Navigate to your Xcode beta and pop down to Contents/Developer/Platforms. From there go down into any of the Mac platforms, e.g. MacOSX.platform and then to Developer/SDKs and into another platform, e.g. MacOSX10.11.sdk. Next enter System/Library/PrivateFrameworks/Swift.
