skiing: an advanced lesson with the master

It’s hard to get better by skiing on your own. Teaching less talented skiers hones your technique, but doesn’t stretch you. So I paid for a private lesson. I’ve wanted a lesson from Elianne “El” Furtney for a decade, but she’s risen way past Level 3 ski instructor and is somewhere up around clinician / district examiner / regional demo team — she teaches the teachers who train ski instructors who teach the common folk. But relaxed ace Tim Reeve, with multiple appearances in Ski Magazine’s “Top 100 instructors in the USA” list, was available.

He mainly focused on my feet. The three parts of a turn are initiation, control phase, and finish, and you use three corresponding parts of your foot: you move onto the toe of your new outside leg to initiate, then ride the arch in the control phase, and finish with your weight towards the heel. In steeps it’s a quick swing from new toe to heel, with very little time spent riding the arch (unless you want to reach mach 3!), but in moderate bumps and easier terrain it’s a long smooth count along your foot. Working from the feet lets you control turn shape; Tim says he visualizes a black curve down the hill and follows it with his feet.  I came into the lesson worrying about my upper body position and my left foot railing to the outside thereby blowing the turn; just trying to draw half-circles with my feet made those problems go away! Ding ding, $179 well spent. Maybe less-experienced instructors focus on your arms, upper body and hips because it’s easier to see what those body parts are doing.

In steeps, Tim reminded me to have my upper body facing where I’m going. Thus in aggressive fall-line swing turns, face downhill and reach downhill with the pole plant.  I tend to let my skis turn me across the hill, so I need to consciously rotate my upper body opposite to the way my skis turn — “counter-rotation”.  Also in steeps, you shouldn’t initiate turns with a step onto the big toe of the new outside ski because that pops you up and away from your skis and your descent.  Instead it’s a press toe-and-(immediately)-down! motion. I was completely unable to do this and face downhill at the same time.

We talked about riding that outside foot and how hard it is for intermediates. You have to put some juice into it, but if you push it away from your body you lose control and end up straight-legged using your hips to turn the back of the ski. I tell skiers to “stub out the cigarette” or “squish the grape under the ball of your foot”, and try to get them to feel the pinch in the hip, lower the outside hand to “pat the dog”, face downhill as the skis turn: all ways to load up the outside foot while still keeping it on edge. Tim keeps it simple: he tells students there’s a skateboard in the driveway and they need to put a foot on it and steer it through a turn; that model of a turn gets you onto the foot without all the complexity.

Actually propelling my upper body into the next perfectly carved turn like a racer didn’t happen (the same missed goal as a previous lesson — skiing is hard!); Tim says that’s timing.  And it was a slushy warm afternoon so we didn’t get to work on ice; Tim says that’s just adjusting pressure, maybe even retracting skis. ‘It’s called “the touch”,’ he said, mystically. I’ll get there some day.

software: Fedora 15 feedback

The Fedora 15 announcement says

A list of the problems we already know about can be seen on
the Common F15 bugs page,at  http://fedoraproject.org/wiki/Common_F15_bugs.

If you find a bug that's not found on that page, be sure it gets
fixed before release by reporting your discovery at
https://bugzilla.redhat.com/ Thank you!

But there’s nothing on the Common F15 bugs page, and filing a bug for each of these vague comments is impossible. So here’s my brain dump. If I were a well-known reviewer, people passionate about the project would jump in and respond to these, file bugs for some of them, discuss workarounds, etc. Oh well.

Boot/device problems

Running livecd-iso-to-disk from the Fedora ISO on Kubuntu 10.10 seemed to work, but my PC gave me the SYSLINUX boot: prompt. It seems Ubuntu 10.10’s syslinux version 4.01 puts an ldlinux.sys on the USB that doesn’t find syslinux.cfg in a subdirectory. After I repeated syslinux command with latest 4.04, it booted up fine! (I filed Fedora bug 699554)

Brief flash of text console at one point.

Same Pulseaudio problem with audio devices as in Kubuntu: my built-in VIA 8237 audio and Audigy ZS card are both labeled “Internal Audio Analog Stereo”, no distinction.

Terminal

When I’m in the Terminal, its  “icon” background in top menu bar looks like a rendering glitch and/or collection of subtle window system indicators (>_)

The terminal bell sound is wayy! TOO LOUD!!!  It’s much louder than other sounds.

Why no sudo?

liveuser is not in the sudoers file.  This incident will be reported.

Sound Settings control panel

Terminal bell sound is wayy! TOO LOUD!!!
Changing Sound Settings > Sound Effects > Alert volume has no effect on terminal bell volume.

When I choose an alert sound, the first ~0.2s of it repeats endlessly, and Sound Settings locks up.  I have to Force Quit

Sound Settings Output tab should have a [Test] button as KDE does.

UI Toolkit

In GEdit Open Files dialog, it’s wrong that symlinks don’t appear in italics.

In GEdit, how come Ctrl+Tab, Ctrl+PgUp, Ctrl+` don’t switch between tabs?!

Rhythmbox music player

The first time I started it Rhythmbox warned “Cover art plug-in not found (roughly).

It would be so nice if live USBs came with a few sample songs and images!!

Window controls

Bottom bar

When I move the mouse to the lower right, a bar fades in with “Rhythmbox” in it.
If I right-click on this, there’s an Open command.  But:

 

  • If Rhythmbox is minimized, it doesn’t reappear.
  • If Rhythmbox is under other windows, it doesn’t pop to the top.
  • Basically this doesn’t do anything?

Moving windows

The blue shade for half-screen is nice, but if I move Firefox towards the edge it pops to fill the whole screen, and there’s no indication this is happening.

When a window is half-screen, there’s no indication this is the case, so it’s puzzling there’s no resize cursor on the visible edge.  And there should be a resize cursor, why not let me resize a half-screen window to be 2/3 screen!

Activities

Activities menu item at top left

Click and hold and Right-click do nothing.  This is unlike every other icon in the top menu bar!

Activities screen

Type “IRC”, nothing shows up!  I need an IRC client! Maybe it’s Empathy.
Type “Chat”, Empathy appears.  But there’s no description of it.  The KDE Start menu has the name and a few words of description, and can search on both. That’s much better.

While Activities is up, Alt-Tab to return to a different window doesn’t work.
Can’t use tab or Ctrl-tab to switch between Windows and Applications view.  Are these tabs? They seem to be, so I don’t like Windows and Applications buttons sitting on the desktop.

Activities > Applications list

  • the font is too small
  • the ‘A’ in application names like Add/looks bad, the first stroke is ragged
  • arrow key doesn’t move around list
  • No right-click menu on apps that appear in Applications.

Help

Help > Go > All Documents… where’s the Gnome Shell document?!
Ahh, it’s Desktop help.
The detailed text for Desktop help is… Desktop help. It should be “Guide to Gnome gesktop shell”.

computers: trying new distributions

I’m still running the Kubuntu flavor of the Ubuntu Linux distribution, now up to version 10.10. It’s lovely that Linux distributions get steadily better for free, and thanks in a small part to my bug reports and testing.  The glitches I had with Ethernet are gone, it better understands my sound cards, etc.

But 1 GB of memory isn’t enough to run a browser. This is hard to believe, so I thought I’d try some other operating systems to see if they have less resource needs. Windows and Mac users don’t realize there are lots of free operating systems out there, and that you can try them out by “simply” downloading a CD-ROM image and burning it to a CD-R or transferring to USB flash drive. Microsoft and Apple’s operating system business depends on you not being able to make your own bootable copy of their operating system, but free open source operating systems want you to do this and share the tools and utilities to make it easy.

Chromium OS

While Android goes from strength to strength, Google is still developing Chrome OS, a lightweight Linux operating system that runs a browser. That’s pretty much what I want. Because it’s open source, you can adapt Chrome OS to work on other computers. That’s what the teen hacker from the UK “Hexxeh” has done, he builds a version of Chromium OS every night.

Bottom line: it didn’t work for me. Either his build doesn’t support my ATI video card, or Chromium OS requires more advanced graphics than my card implements. In theory I could build my own version of Chromium OS, but it’s very complex.

New Linux desktop experiences

The Ubuntu Linux distribution and the Gnome user interface project have both committed to next-generation desktop projects, Unity and Gnome Shell respectively. Much gnashing and wailing about duplicated efforts, lack of code sharing, etc. And when people review the resulting desktops it tends to be superficial “I don’t like it” responses.

Fedora 15

I supported the inspiring vision of One Laptop Per Child vision through its Give One Get One program (I think my given one went to Rwanda), and my XO-1 laptop uses a Fedora spin, so I’m familiar with it and impressed by their work.  So I thought I’d give it a try, and also check out Gnome shell.

I reused the USB flash drive that had the failed Chromium OS build on it. First I had problems with arcane cylinder-head geometry issues when I rebuilt the drive. Then I discovered that although Fedora’s script to make a live USB runs without errors on Kubuntu and ends with "Target device is now set up with a Live image!", it is actually incompatible with the Ubuntu 10.10 system utilities.

With those out of the way I finally booted into the spiffy Gnome desktop, where I’m typing this blog post. And… it’s hard to tell. Maybe Fedora 15 is using less memory. Maybe I’ll like the new, very different, desktop. Meanwhile I have a ton of beta feedback.

computers: one billion bytes of RAM isn’t enough

I’m typing this on a Falcon Northwest top-of-the-line desktop computer. It’s from 2004. The Athlon 3000 dual core CPU can keep up with most of my needs, the 100GB disk has enough space, the audio is fine, the video can display a large desktop.  Latest 3D in the browser doesn’t work, but day-to-day surfing and video playback is fine.

The killer problem is its memory. 1 GB of RAM ( 8,000 times the RAM of my Macintosh 128kB!) is no longer enough to surf the web. Far from setting us free from the tyranny of updating our computers, browsing has become the most demanding application we run, unless you’re a 3D video editor.

  • I’ve abandoned Firefox and Thunderbird to revert to the integrated Mozilla suite SeaMonkey (the continuation of the original Netscape Navigator suite) so that I only have one monster program using up all my RAM.
  • I’ve limited the amount of memory that any program can consume (ulimit -v 1360000) to try to make Firefox/SeaMonkey crash faster when it runs out of memory.
  • I’ve disabled some of the KDE desktop services such as its desktop semantic search and central contacts/e-mail manager (thereby making the desktop even more of an irrelevant “programs strip at the bottom below the browser (and terminal window) where I do all my real work ”

Nothing helps.  If I open more than about 7 tabs, or if one of them is “aggressive”, I wait for my computer to lock up.

It should be easy to solve this problem, just buy three 1GB sticks of PC3200 memory. But 7-year old memory is quite expensive, about $50 a slot.  Best Buy has a deal on memory I’ve never heard to get 2GB for $60.  So as usual, buying a top-of-the-line computer for a lot of money doesn’t avoid obsolescence, it just postpones it.  A quality computer will work for years, but after a few years it’ll be off the pace and upgrading it will be expensive. It’s better to buy a cheaper computer and get a new one every three years, or sooner if it breaks.

books: Richard Ford’s dispassionate adultery misses his peak

far from his best

Jan 01, 2011 by skierpage

★★☆☆☆ Richard Ford‘s short story The Womanizer in book 40 of the Granta literary magazine knocked me out, perhaps my favorite modern short story until The God of War came along , so I got this book. Alas no story in the collection comes close, they’re all variations on his lesser The Shore in Granta 50: adulterous man in a cool relationship doesn’t recognize how bad he is.

books: a dull book about design

Just terrible

Apr 22, 2004 by skierpage

★☆☆☆☆ One of the lamest books I’ve ever read. Henry Petroski rambles on about the design of supermarkets, toothbrush holders, stair treads, potato peelers and his Volvo’s cupholders, but there’s minimal historical research or thinking involved. Apart from a section on paper bag design, the trite conclusion of every chapter is the same as the book’s subtitle Why there is no perfect design.

web: Amazon Cloud music, digits online, and piracy

Amazon’s Cloud Drive/Cloud Music Player is intriguing. It lets you play music from an online storage folder. It’s easy for Amazon to implement since they already have all the music files, so the millionth user with a hit song doesn’t take an extra 3MB of storage, just another pointer to one copy of Lady_Gaga_Born_This_Way_240kbps_high.mp3. Amazon will offer this for every MP3 you buy from them, so it’s a competitive feature for their music store against the iTunes juggernaut.

It’s a kick in the pants for Google that Amazon beat them to it:

Google has nearly all the pieces to do the same: I can already upload music files to Google Docs, Google has a checkout and an Android app store. I’m sure it’s a humiliating wakeup call that Amazon got there first. Google Docs even has the nifty “Share” feature, though enabling it for music would trigger yet another epic legal battle.[me on Slashdot]

I’m a very minor pirate, I don’t think I’ve ever pirated something that wasn’t freely made available to me or that I can legally purchase. But it’s fascinating to imagine the ways that companies’ control over 1s and 0s can be subverted (my thoughts on pictures) thanks to their innate fluidity and infinite replicatability. Here Amazon is letting me access my music from any device anywhere. My.MP3.com tried something similar and was sued into oblivion. But you don’t need a company to provide this service, and who is “me” exactly? When it comes to digital files,

The benefits to storing your music collection online are so great that many people must already be doing it, including the intersection of rich and record collector. Karl Lagerfeld must get tired of lugging his Louis Vuitton trunk-ful of iPods around, I’m sure Elton John is back to acquiring vinyl, I doubt Music Man Murray is going to delete the MP3s of his 300,000 records.

I don’t see what’s illegal in storing your legally-purchased music in your own online storage. I don’t think the record companies can force you to keep the username and password of your online music folder private, any more than your car company can force you to lock your car up. The reason people don’t share a read-only password is they’d have to pay their ISP big bandwidth fees when huge crowds come to freeload. But the rich can afford it. When will some celebrity, Russian oligarch or Chinese billionaire, mad at the record companies and eager for infamy, go anarchist value-destroying Robin Hood for us and let slip that the username:password for http://RomanAbramovich.ru/AllMyMusic is boris:Chelsea ?[me on Slashdot]

art and excess: $1M Red Tibetan Mastiff vs. Jeff Koons’ Puppy

A multi-millionaire coal baron in China just bought “Big Splash”, a red Tibetan Mastiff, for $1.5 million because “they have become highly-prized status symbols for China’s new rich.” The dogs are thought to be a pure “Chinese” breed and they are rarely found outside Tibet, giving them an exclusivity that other breeds cannot match. Translation: this mobile conversation piece is a sickly inbred dog from the mother of all “bubble breeds” Compared with most pure breeds, mutts from the pound are the six million dollar man: stronger, smarter, longer-lived. Genetic diversity rules.

Big Splash’s weird color and 180-lb heft will impress other billionaires , but is no match for Jeff Koon’s “Puppy,” a sui generis symbol, according to Koons, of “love, warmth and happiness”. One of the litter costs Stephanie Seymour’s ex-husband $100,000 a year in flowers to maintain. I love this  this non-review of “Puppy” by Peter Schjeldah in The New Yorker:

I remember my first encounter, in Germany, in 1992, with Koons’s famous “Puppy,” the forty-three-foot-high Scottie dog enveloped in living flowers. As I was judiciously taking descriptive and analytical notes, a bus arrived bearing a group of severely disabled children in wheelchairs. They went wild with delight. Abruptly feeling absurd, I shut my notebook and took instruction from the kids’ unequivocal verdict.

software: Google/Android doesn’t know how to link

(I wanted this in Thunderbird, now I long for it in Google apps and Android.) 18 years ago, before there was HTML and http, the Perspective personal information manager software could take the text lunch tomorrow with John at Monk's and create a calendar appointment linking to the Bob Smith and Monk’s coffee shop records in my address book. Now computers are 250,000 times faster, UIs can autofill a dropdown list of every web site or common search term as fast as I type each letter of Lady Gag…, we have O.S. and network level APIs to link anything with anything.  So how do Google apps compare with decades-old technology?

Calendar event (meet John Smith)
Nothing!  Desktop Calendar’s Quick add feature even taunts you with its “Example: Dinner with Michael 7pm tomorrow but it parses 7pm tomorrow and ignores the Michael sitting in your contacts list.  I can add his e-mail as a guest of the event, but that generates e-mails and invitations to him; this is information for me, not social networking or some sort of eVite wanna-be party planner.
Call alarm (phone John Smith 10:20 Wednesday)
Sanyo dumb phones have had call alarms for over a decade.  You create one in the contacts or calendar app, and at the scheduled time you get an alert with a big button that you can click to place the call. Android has no such facility, either implicitly by typing this or explicitly by clicking [New call alarm]. Instead those words are meaningless to it, so when the event notification goes off it makes me screw around going between apps and re-typing. I’ve already given it the action and the data, it’s just too stupid to realize it.
Task list (discuss project with John Smith)
(Tasks are a feature in desktop GMail and Calendar, but they don’t show up in Android 2.2) Nothing! No way to go from the text to the contact, no way to tie them.
Maps (John Smith)
Good! As I type a dropdown shows matching names from Contacts with their locations
Event location (Monk's coffee shop)
Unlike Maps, Calendar doesn’t autocomplete from all my contacts with locations, nor does it show recent map locations. And since Calendar doesn’t realize I’m meeting John Smith, I can’t even tell it the location is his home address that’s sitting in contacts. And when I later tap/click the location to show it in Maps, Maps doesn’t consult my address book as it does while I’m typing, it only does a dumb web search. It’s a quadruple fail!

A wiki allows you to easily make explicit links of this sort using simple markup; if you write meet [[John Smith]] at [[Monk's Coffee shop]] it will turn the things in square brackets into hyperlinks to those wiki pages, whether they exist or not. And wiki pages have “What links here” to expose the connections, or you can go semantic web and assign meet_with: and location: properties to the links. That doesn’t seem Google’s style, but they can do the instant drop-down thing; as you type the app should opportunistically look for matches with contacts, and if you auto-complete not only save you typing the rest of …k's coffee shop, but establish a bidirectional link between the event, event location, or task and the contact. Far from doing this, Android text fields instead autocorrect names that are in Contacts, turning Pastine into “Pastime”.

Software that did the right thing was available decades ago, so why are computers getting worse at understanding?

“call John Smith”

web: Why is there Facebook at all?

Social networking sites are weird. All they do is host shared bits of data between groups of people they mislabel as “friends”. But why on earth do we store our  private thoughts, pictures, and information on a central site that hands all this over to marketers and government agencies? For decades we’ve sent e-mail privately amongst ourselves, yet dress communication up slightly differently as a status update and some comments, and we uncritically hand everything over to Mark Zuckerberg.

It doesn’t have to be that way. We should all be doing direct person-to-person social networking.  Your toaster cable modem, wireless router, or smartphone is powerful enough to send and receive encrypted pictures, status updates, and comments to/from lists of people you control, then your browser can assemble your own “Top News” page from the bits of data. The data is independent of the presentation, so you could have some browser pages (call them “web apps”, but you don’t need a network connection) that show messages and responses, others that show a visual timeline, others that show all the links… The great thing about this is that if your computer crashes, your toaster cheap networked gizmo can just contact all your associates and reassemble the pictures, comments, messages you’ve shared with them.

Together we can kill Facebook, we just need to zz[CONTENT DELETED BY mzuckerberg~~~privilegesTerminated]
