Rip. Mix. Burn.

Thank goodness for CDs. I don’t know how life is going to change once I can’t own my music.

Look, I know that this whole streaming thing is where you live now. I get it. You’ve got a subscription, and you get to listen to what they provide you, available 24-7 on your phone and computer.


Spotify may be working for you, but it’s not working for me. It doesn’t have what I want to listen to.

Sometimes it does, I guess. But sometimes not. The very first song I tried to find on Spotify this evening was Lene Lovich’s New Toy, a classic on KROQ back in the 80s. And near as I can tell it was on Spotify at one point, at least according to this guy’s playlist that he put together. New Toy is grayed out, for some reason, and doesn’t show up in any searches. I guess it’s gone.

Where’d that song go?

You know what’s not gone? The MP3 on my computer that I legally ripped from a CD that I own.

I had a bit more luck finding Pink Floyd’s Meddle album. Well done, Spotify. And Old Hag You Have Killed Me by the Bothy Band. Excellent. I shouldn’t trash them too much for their selection. They’ve got enough to worry about, what with the criticisms regarding their payment to artists.

Spotify has most of what I want, okay, but it doesn’t have everything I want. The Lene Lovich example above is something you’ve almost certainly lived yourself, perhaps on Netflix when you went to watch a show that you’d seen their before, only to find out that some licensing agreement had expired and the show is no longer available. It happens all the time.

So where music is concerned, I’m still buying CDs. I’ve heard some exaggerated rumors concerning the death of physical media, but it’s not dead yet. I’m buying physical media and ripping it on my Linux box to FLAC (of course), transcoding it to MP3s using the Apple app XLD, and living large.

CDs will go away someday, of course, and I’ll have to get my bits elsewhere. But I dearly hope it’s the bits that I’ll be buying, as opposed to a license to temporary access to those bits, revocable at any time.

In related news, Microsoft has been selling digital books via the Microsoft Store since 2012. Cool, yeah? Oh, wait. Microsoft has pulled Books from the Microsoft Store and is planning to offer customers who’ve purchased any ebooks via the Store refunds, as their books will no longer be accessible as of July, 2019.

Oops. Guess the money I paid for those books wasn’t actually a “purchase.” It was a “user agreement.” My bad.

Hang on to your data, folks. And make backups. ;)


21-24 January 2016

This weekend, the Southern California Linux Expo came to Pasadena. I’d met my brother Kevin at SCaLE 12x at the LAX Hilton two years ago, but the convention had outgrown that hotel, and a tech-friendly Pasadena councilmember thought that bringing them here to the Pasadena Convention Center would be a good idea.

It was. There were 3000+ hardcore geeks who descended on the town for the weekend.

You know it’s a Linux convention when the nervous nerd walking on the sidewalk looks up at you, takes note of your event badge, and actually says ‘hi’ to you.

On Saturday, Jan 23, eleven students from Polytechnic School—M Yen, K Callero, M Flannery, G Hashimoto, C Hicks, D Magsarili, J Wong, M Xu, C Strassle, M Berke, and J Lang—attended the event, including the SCaLE Youth Track, various other sessions, and the Expo. We learned about the Open Source movement in general, Linux in particular, and met some great people.

It was awesome.

Since the Expo:

  • I’ve been contacted by multiple parents saying how much their kids enjoyed the event, and asking for further info/opportunities like this.
  • I’ve been in email contact with Tom Callaway about a new CS course I’m writing.
  • I appear to have stumbled into a mentoring relationship with a local teacher-in-training with whom I struck up a conversation while leaving Callaway’s talk Sunday morning.

Thank God for Mac OS X

Thank God for Mac OS X

by Richard White


There’s a line that rock climbers sometimes trot out when they feel like exulting in the glory of their source of creativity.

“Thank God for the rock. Otherwise, we’d all be surfers.”

In the same way, it has occurred to me on more than one occasion to say to myself “Thank God for Mac OS X. Otherwise, I’d be using Linux.”

Now the reality of the situation is that Mac OS X and Linux share a common ancestor: UNIX. Actually, the Mac OS X running on all current Apple computers really is UNIX at its core. I’m thankful to the Mac platform in part for giving me a jumping off point from which to learn about UNIX, and later on, Linux. In 2004, O’Reilly published Learning Unix for Mac OS X Panther, by Dave Taylor & Brian Jepson, which turned out to be a great to begin discovering some of the inner workings of the OS X operating system.

One of the best things about OS X, then, is the fact that one can peek under the hood and play around with things a bit. This has always been the case with computers, of course, but OS X’s use of UNIX means that there’s a fairly large base of users with UNIX experience that can assist one in playing with the system, or even running other software on the system—UNIX-based software—that actually isn’t part of the official OS install.

This past week, Apple released the long-awaited 10.7 version of the OS X operating system, named “Lion.” Apple has continued to improve on OS X over the years, and this release included some major developments that many users are going to find very appealing, including autosave, built-in version control, and updates to many Apple apps.

Some users, however, found some of the improvements to be less-than-satisfactory. In an otherwise clean and minimalist User Interface, for example, Apple’s iCal application sports a faux-leather and torn paper skin that is almost universally abhorred by users, for a lot of different reasons: the leather is inconsistent with the overall OS theme, the real life stitching and leather texture don’t contribute to one’s understanding or use of the application, the fake torn bits of paper on the upper margin are silly…

Fortunately, the power of the community stepped forth, and someone came up with a package that allows one to equip that calendar with a skin more appropriate to the UI, and made it available online: Thanks to the carefully written instructions there, my iCal calendar is back to looking like it should.

Apple’s program received some interface changes as well, and that got me thinking about investigating some other ways of working with my email. Of course many people have already gone over to using a Web-based email system—Google’s Gmail is the most popular—but I still like the idea of being able to read and compose emails when I’m not actually connected to the Internet; I like having an email “client” on my local machine.

If you’ve used Apple’s Mail, or Microsoft’s Outlook or Outlook Express, or any one of a dozen other programs that run on your local computer, you might be interested to hear about another alternative, one that may appeal especially to the geeks among you.

Next time, we’ll see how to install a modern version of the Terminal program pine on your UNIX-based OS X machine.

Building Your Own PC, part 1 – Introduction

Building Your Own PC, part 1

by Richard White


After many years of hearing about how much fun it was, I finally jumped into the pool this April and built my own desktop PC. It was, in a word, AWESOME, and I heartily recommend that you do the same.

I have a rep as being something of an Apple fan, never mind the fact that I’ve also got Dell and Lenovo laptops dual booting Windows and Ubuntu. The unfortunate truth, however, is that Apple is so picky about making sure their hardware is built to specification, they don’t allow anyone to do it but themselves. I’m not complaining–the results of this policy speak for themselves. But if you’re going to build your own desktop, it’s going to be a PC running Windows or Linux.

And before we get too far into it, let’s be clear: we’re not talking about soldering integrated circuits or transistors onto a circuit board, and testing your electrical engineering skills with an test oscilloscope, or anything ridiculous like that. What we’re talking about is you taking some time to:

  1. Decide what you want to use your new computer for
  2. Settle on components that you’ll be using to assemble your new coputer (even if you’re not really sure what those components might be at the beginning)
  3. Poking around on the Internet looking for advice and good combinations of components that will make the machine you want
  4. Ordering those components online (most likely from and
  5. Patiently waiting for those components to arrive
  6. Finding a few hours when you can settle in and try to assemble everything
  7. See that you’ve made a mistake in one or two items that you ordered, and send the ones you received back in to be replaced with what you really wanted
  8. Get new components, and assemble them into your dream machine
  9. Boot into the BIOS, and fix things that may not be working
  10. Install the operating system of your choice, as well as updates and drivers as necessary
  11. Install additional software as desired
  12. Admire your awesome machine!

As you can tell from some of the steps on the list up there, things don’t always work the way you’d thought they would the first time. While this is almost certainly going to be a source of frustration when it happens, you should also look at it as an opportunity to come to a better understanding of the hardware, and a chance to appreciate just how much work goes into getting these things to work the way they’re supposed to.

I’ll tell you how I began the process of building my own machine next post. In the meantime, you have three homework assignments.

First, start thinking about what kind of machine you’d like to build. Is it going to run Windows, Linux, or both? Is it going to be a lightning fast gaming machine, or medium-fast machine that you’ll use for surfing the internet and reading email, or a slower machine that you’ll use for backups, or serving media to other computers at your house? The uses you envision for your machine will determine the design and components you select.

Second, see if you can’t scrounge up a spare mouse, keyboard, and LCD monitor that you can use. You can use borrowed gear for these items at first, at least until you get your machine up and running. If you want to get fancier custom keyboard, mouse, or monitor, you can certainly buy them when you get the components for your computer, but they’re not strictly necessary. (In my case, I pulled an old keyboard and mouse out of the dumpster, and asked the tech people at my school if they were throwing away the old 15″ LCD monitors I saw sitting out in the rain.)

Third, do a little background reading on the Internet to help you figure out what you might want to include in the design of your new machine. Each article / website here comes highly recommended:

Next time? “What’s in all those boxes??!”

Nose, Face, Spite. Fast-twitching.

Nose, Face, Spite. Fast-twitching.


by Richard White

The curse of the fast-twitch response neural response (and I’m perfectly aware that I’m mixing a muscle property with brain activity in that metaphor, but go with me on this), is that emotions can blaze along as quickly as thinking does. I like to think that I’m relatively quick in grasping the fundamentals of a problem, or seeing through a tangle of talking points to a logical conclusion, but I occasionally find myself at the mercy of sudden and strong emotional responses to situations.

Ask teacher/fellow-geek Aaron about the little jaw twitch I get right before I freak out. He’s seen me in enough stressful situations to know the warning signs.

I’m not twitching right now, but I was a little troubled last night to read this bit of news from the well-connected John Gruber:

A few months ago, I heard suggestions that Apple had tentative plans to release a developer beta of Mac OS X 10.7 at WWDC this June. That is no longer the case. Mac OS X 10.7 development continues, but with a reduced team and an unknown schedule. It’s my educated guess that there will be no 10.7 news at WWDC this year, and probably none until WWDC 2011.

Apple’s company-wide focus has since been focused intensely on one thing: iPhone OS 4.1 The number one priority at Apple is to grow mobile market share faster than Android. Anything that is not directly competitive with Android is on the back burner.

Okay. That’s not good.

My deal with Apple is simply this: deliver products that are better than the competition by a factor of two or three, products that make me happily spend top dollar for their outstanding quality and Apple’s superior customer support. Do that, and I’m your fan-boy. Ever since I switched to Apple from the PC world almost 20 years ago, they have delivered on that promise.

And for the moment, I guess they still are, although the iPad isn’t part of that promise for me. Nor the iPod, nor the iPhone. For me, Apple’s superiority has been its hardware and its software, all built around the rock solid OS X, running on top of the Darwin flavor of UNIX. It’s been a great ride, and I owe so much of my own technological workflow to those, and the third-party apps built for that ecosystem.

If Gruber’s intuition is true, though, any significant growth or evolution in that ecosystem has been stunted, as all hands on Cupertino’s deck rush toward the various mobile platforms—iPhone and iPad. I’m not saying that they shouldn’t devote significant attention to that front: I’m an Apple stockholder, and while the rest of the world is struggling to emerge from that “economic downturn”, AAPL is doing just fine, thank you. When I wear my investor hat, I’m a happy man.

But put on my technology hat and I start to get a little worried. Development on the new operating system, as mentioned above, has apparently slowed or stopped completely. And the top-of-the-line laptops haven’t come out with a significant refresh in years. I used to be an an 18-month hardware upgrade cycle, based both on the release cycle from Apple and the amount of stress I put on my machine, carrying it back and forth to school, to classes, to office, to home… The machine I’m composing this post on is almost three years old. It’s serviceable, but… Apple’s development has slowed in this area as well. Let’s see, three years ago… that was just about the time that the iPhone came out.

Apple is currently struggling to serve two masters: the geeks and the public. Not all of the geeks are real happy right now, and some of them occasionally make noises about jumping ship in favor of other, more open, worlds: Google’s Android-based phone systems, Linux (including my personal favorite, the excellent LinuxMint), etc. Sometimes, they come swimming back to Apple, in a classic case of “I’m sorry… you were right… turns out that the grass isn’t as green over there as I thought it was…”

Regardless of what happens, it’s going to be fascinating to watch.

I’ve been told as an investor that I need to be smart, and not think with my heart. For years I’ve invested in Apple more as a result of my strong belief in their products rather than any deep financial analysis. I suppose it’s a bit ironic that, with their stock at an all-time high, I find myself believing in them a little less than I did before.

At least until the new MacBook Pros come out.

Me, next week, when that happens: “Oooooh! Shiny!!! I love Apple!!!”

Ah, the curse of the fast-twitch neuron.

Here comes Linux, part 3

Here comes Linux, part 3


by Richard White

Linux Mint has lots of software included with it: Firefox for browsing, Pidgin for chatting, Thunderbird for email, OpenOffice for working with Microsoft Office documents (Word documents, Excel spreadsheets, PowerPoint presentations, etc.)

Chances are, though, that you’ll want to add software on your Linux machine, just as you would on any Windows or Mac machine. I know I did. I wanted to add Skype so that I could videoconferencing capabilities to my nifty little netbook. Other software I’d suggest you consider downloading more or less immediately is DropBox (cross-platform, cloud-based filesharing/syncing between all of your computers) and VLC (cross-platform video playback software).

Let’s look at how you install software on a Linux machine.

There are basically 3 ways, depending on what it is you want to install. In order of increasing complexity, you can:
a) use a “package manager” application that will help you find a install selected programs that have been prepared for your particular distribution;
b) download packages from the Internet and install them yourself;
c) download packages and “compile from source”.

If you’re brand new to Linux, you’ll probably want to stick to the first technique for now–it’s easier for you and safer for the data on your computer. Let’s see how it works.

Installing Skype (using the Linux Mint (Ubuntu) installer):
a. From the Linux Mint logo in the bottom-left corner, select Menu -> System -> Software manager
b. Click in the Search box at the top of the mintInstall window and enter Skype
c. Select Skype when it gets found, then click on the “Install” button.


After the installation process is completed, go ahead and close the windows of the installer. You may need to restart the machine before some applications will work. You can launch the new application by clicking on Menu -> Applications -> Internet (in the case of the Skype application), or Menu -> Applications -> All applications and selecting it from the list there.

If you decide that you’ll be using this application, or any others, more frequently, you can click-drag the application from the Applications window down into the bar at the bottom of the window. Once the icon is down there, you can launch the application by just clicking on that icon.

We’ll talk a little more about the other ways that you can install software at some point in the near future. In the meantime, just because we’ve installed Skype on the Mini 10v, don’t think we’re in the clear yet! If you launch Skype, you may well find that the video works just fine, but the internal microphone on the Mini 10v doesn’t work.

What’s up with that? Investigation is ongoing…. In the meantime, if I need to run Skype, I’m using the Macbook Pro. “It just works.”

Dell Inspiron Mini 10V
The laptop showed up today.

The little Dell Inspiron Mini 10V, pretty much the cheapest little computer that you can get these days, showed up at work in a package quite a bit smaller than I was expecting. I cracked the cardboard open, lifted the lid, and raised my eyebrows. “Wow. That thing is small.”

Kevin the receptionist looked interested, so I pulled it out of the box and handed it to him. “Wow! That is small! You knew it was going to be that small, right?”

I guess I did. I’m not sure I knew it was going to be that small, though. I opened it up to find that the screen was even smaller (still 10-inches diagonally, as expected), but that my hands rested comfortably on the 92%-of-full-size keyboard. The school day was over, but with the arrival of the new machine, I was anticipating that I’d be spending the next few days getting this machine set up.

On this particular evening, though, the task was simple: get Linux Mint installed on the machine.

If you’ve never installed Linux before, there are a number of ways to do it. The easiest by far is to take a CD for a particular distribution (Ubuntu, Knoppix, Linux Mint in my case), boot the machine using that CD, and then install from the CD. I’ve done that before on a number of different machines, and it’s a relatively straightforward process that involves (usually) answering a few questions so that the operating system can be configured to your needs.

For the Dell 10V, the process is somewhat complicated by the fact that it doesn’t have a CD drive. Welcome to the future. Blue-Ray to the contrary, some machines are already losing their optical drives, which allow machines to be small & lighter, or to use valuable space for solid-state drives or batteries. But… how am I going to install the new operating system then?

Enter the flash drive. Modern PCs are able to boot from a flash drive, so it’s a “simple” matter of putting Linux Mint onto the flash drive and making that drive bootable, which I’d been smart enough to do a few days before. The excellent instructions at explained how to get Linux Mint 7.0 onto a flash drive, which goes something like this:

  1. Download the Linux Mint 7 ISO.
  2. Burn ISO to a CD
  3. Insert your Linux Mint7 CD into a PC and boot from it. You’ll be running Linux Mint at this point off the CD. You can use the CD to install Linux Mint on the PC if you wish, but what we’re really interested in doing is creating a bootable USB flash drive for the laptop.
  4. Insert the USB flash drive into the computer running Linux Mint.
  5. From the list of Applications, open Terminal and type:
    sudo su
    apt-get install usb-creator
  6. In USB Creator
    1. Select the USB disk
    2. Click the button “Make Startup Disk”
  7. IMPORTANT: Download a custom Linux Mint 7 syslinux.cfg file from and copy it to the syslinux directory on your flash drive (overwriting the original).
  8. Eject the USB drive with Linux Mint on it.

So then I waited a few days until the Dell Mini showed up, and didn’t even really bother to boot into Windows XP, although I suppose I could have done that. But I’m a working man, and I don’t want to have to mess about with malware, viruses, and such, so I just decided to jump in and install Linux Mint on the entire thing:

  1. Insert the USB drive into the Dell Mini 10V while it’s turned off.
  2. Startup the 10V, and tap the F2 key a few times just as soon as the Dell logo appears in the startup process. This will get you into the BIOS and allow you to choose the USB drive as the startup disk.
  3. Use the right arrow key to select “Boot” in the top menu. Arrow down to select “USB Storage”. Use the F6 key to move “USB Storage” to the top of the boot list. Now, when the computer starts up, it’ll check the flash drive for a bootable device, which will allow your Linux Mint USB drive to start up the computer.
  4. F10 to Save & Exit the BIOS, and the computer should boot up off the flash drive.
  5. Follow the on-screen instructions to install Linux Mint 7 on your Dell Inspiron Mini 10V.

Here comes Linux, part 1

“Are you kidding me???” Dee shouted in disbelief.

I’d just told her that I–a faithful Mac user for the last twenty years–had ordered a Dell Mini 10v.

“Are you KIDDING ME??? she shouted again, thinking perhaps that I hadn’t heard her the first time.

“Yeah, I know…” I went on to explain that I’m not giving up the MacbookPro. And I’m definitely not using Windows (no offense). I’ve been looking for a decent portable on which to install Linux Mint, and after passing on the idea of a Lenovo ThinkPad (high quality, but a little higher-priced especially for a second machine), I fell for the “$100 off, free shipping” email that I’d gotten for the Dell.

This is more than just Black Friday extravagance. I’ve been intrigued by the idea of working with Linux on a laptop for a number of years now, ever since Mark Pilgrim famously made his own switch from the Mac three years ago. His reasons included Apple’s proprietary file-formatting and Digital Rights Management (DRM) lockdowns that make playing by their rules occasionally difficult. The hardware, although of high-quality, is known for being expensive, placing it out-of-reach for many students, and a number of teachers. The question became, is it reasonable for me, as an educational technologist to run most, if not all, of my digital life using Free / Open Source Software?

In addition to other topics being discussed here, I’ll be covering the journey here once the new machine arrives in a couple of weeks. For now, though, I’m anticipating using the following software:

Mac Linux
Operating System OS 10.6.2 Linux Mint 8
Browser Safari, Firefox Firefox (pre-installed w/LinuxMint)
Mail client Apple’s Mozilla’s Thunderbird (pre-installed w/LinuxMint)
Chat client iChat, Adium, Skype Pidgin (pre-installed w/LinuxMint)
Web development client Panic’s Coda Quanta Plus?
Calendar program iCal Mozilla’s Lightning?
Text editor emacs, BBEdit emacs (must be installed using apt-get), gedit (pre-installed w/LinuxMint)
Office apps Word, Excel, PowerPoint Open Office? (pre-installed w/LinuxMint)
Music playing iTunes Pick one
Music editing Garage Band, Amadeus, Audacity Audacity
Image Processing iPhoto, Photoshop Elements, Acorn, Graphic Converter GIMP

Any suggestions out there? Let me know!
