Finished shovelling Sunday nightGood morning. At the right you can see the final results of my third round of shovelling snow for a middle-of-the-holiday-weekend Sunday. It's a bit contrast enhanced because it was just before dusk when I finished. Yesterday's totals were about 8" in the morning, then about 4-5" each of the next two rounds, between one and two PM, and around 5 PM. Into the evening the snow tapered off to a light sleet mixed with snow. Lovely, an icy coat on everything for this morning. We still didn't retire until about midnight last night, for whatever reason. I did sleep like the dead, however, until I woke sneezing my head off and feeling distinctly nauseous.

The patio furniture disappearsThe sneezing is no huge surprise, I've spent a rather considerable amount of time out in the cold dry air - more than I have in several years combined. But I figured out the nausea, too. It was the fresh icy eight inches of snow on the ground. 22 fresh inches in a low spotMy first glimpse was out the back door, where it appears that our patio furniture is going to be in hibernation until well into spring. So I decided it was time for a litttle measurement. I threw on some shoes and slogged out to a spot that I know was cleared down to concrete before it started snowing on Saturday night. The snow is higher elsewhere in the backyard, but I wasn't going to wade too far out. It was 22" deep. So far the weather liars may have nailed it for once - we're right around 24 " for the storm so far. So far...

Another 6 to 8 inches around the car. Sigh.Then I went out to look at what the night had done to all my hard work out front, all day yesterday. Ah, shoot. That's why my stomach aches. It's with the knowledge that I'm going to be moving at least one more major batch of snow. So I geared up, and got started in the backyard first. A fresh path out to the driveway. I cleared a path, and a patch in the yard for Sally to do her business. She can hardly cope in 6 to 8 inches of snow - she can't bound about like a puppy. That pleased her immensely and made certain necessary activities possible. Then I went up front and cleared the snow that had drifted into the covered front porch area, and did the front walk all the way down to the driveway, as you can see at right. There was just a little bit of very light sleet coming down. I figured I'd come in, put up this post, and head back out to do part of the driveway. After all, the radar images on the news show this morning showed the activity tapering off somewhat dramatically.

Well, that plan didn't work out. I've just looked out the window, and it's snowing like the devil again. Sheesh. We can't be trapped here - I'm running out of foods that are bad for me. Aaaaargh! I'll admit to not having gotten much else done - between shovelling, and groaning about shovelling, my time has been pretty full. Last night, I did do one of my periodic major systems backups to CDR for putting in the safety deposit box at the bank - we're up to 14 CDR now. I think the day of the DVD+R/+RW is coming to this house sooner than I once suspected. The tool I used is called cdbkup, its homepage is here. It's a handy, easy to use command-line driven tool. Read the manpages and you'll know everything you need to make backups to multiple optical discs.

I think I'll have a spot of food, a double handful of some pain killer, and a quick lie-down. Seems like the right plan, eh? After all, it appears that I'm not going to get to work tomorrow anyway.

I can't believe it. It's still snowing. It's at about an inch or so now, and trailing off at the moment, with one more band showing on the radar ready to sweep through here in about an hour, and last for a couple. That gets us to noon, when they say that the sun is going to break through. Bah. I've heard that one before!

The icy snow left behind from the sleet during the wee hours of Monday morning proved too much for me - I managed to clear much of the driveway, but have the bottom quarter of that yet to do. Then there's the sidewalk and the berm built up by the continued plowing operations. Before I can do that, of course, I'm starting over at the top, with the fresh snow on the car and upper driveway. Repeat after me: Snow blower.

Meantime, I was up, with a still-upset tummy, from about 0345 to 0500. I imagine that it's related mostly to the medications that I'm taking for my ear. I've only got another day or so of that to go, so I can hang. I got some quality time in with my Programming PHP book, online at O'Reilly's Safari service.

So today is going to be shovelling, and I think I'll puzzle out a setup of Movable Type for a client site on Rocket, too. Should be interesting, see you around.

The driveway, cleared.I promise, soon, that I'll stop talking about snow. But not today. Good morning, more or less. I'm in a state that somewhat resembles my normal upright position. A sad, crumpled parody of that position, but it's the best I can do. I started digging again mid-morning yesterday, and by mid-afternoon, I was done. Through. Finished. Kaput! One of the local ordinances requires that sidewalks be cleared within 24 hours of a snowfall, to make things safe for kids walking to school, postal employees, etc. Now the District and Mongomery County both waived that for the time being.The sidewalks, also cleared. I imagine that Prince George's did too. But I was warmed up, in the groove, and I knew, deep in my bones, that once I stopped, there wasn't going to be any more shoveling for a while, due to crippling pain. So I continued, and cut through the snow all along our frontage. None of the neighbors did, but then, I wasn't going to touch that shovel again. At least for a while.

Right. During the night, our lovely county plow fairies paid us ... several visits, to judge by the height, density, and rock-ice hardness of the berm that's been built at the base of our driveway. I'm either dreading this, or about to give up on today, as well. By that I mean that if I venture out there, and it's too hard to break through, then I'll wait and do it in the afternoon sun, when it's got some melt going. I can't really stand to lose the income, but there's no use killing myself - and I am really, really sore today.


OK, enough whining. I did successfully install Movable Type on a site yesterday, working before and after the day's exercise. There was a bit of go-round as I added support for it to MySQL with the help of Mr. Lincoln. Then I started testing, breaking things, testing again, fixing other bits... It took longer than it should have, but then we run with suEXEC support in Apache. This makes running CGI scripts much, much safer. But the downside is that setup can be a real bear, because the directory and file permission changes that suEXEC requires can challenge the configuration and setup of a complex program like Movable Type. (Or like Mailman, which has security built into it by it's design, directly conflicting with the requirements of suEXEC. It's solvable though. Search this site for the answer to that one.)

So, how do I feel about Movable Type? I dunno yet. I could definitely work with it. It might be considerably easier than maintaining this setup, in some ways. No more having to throttle links. It's pretty configurable, and there are advantages. But I don't know it, and this works... I'll think about it. The advantage to the current method for me is that it's MINE. The way it works, the way it looks, it's mine. If you go back to previous months, and years, you can see how the design of this place has evolved. With MT, if I change the look, then the look changes for all previous posts. I'm not sure I like that. I like change, sometimes, but I definitely appreciate the history, too. Maybe I should offer the same material in both formats... That'd be easy enough. I'd do this post, publish it, pick it up out of the browser, drop it into an MT entry and repost there. The only MAJOR work would be if I did pictures - a LOT of pictures. Ah, but then I could link back into here. We'll see. Your feedback, as always, is appreciated.


Now to see if I'm up to slaying the plow berm dragon. Have a lovelier day than I seem to be having. Later, dudes.

The Campaign for Audiovisual Free Expression

February 20, 2003 -    Updates at 0730

Good morning. It appears that the possibility of snow last night didn't materialize. That's good thing number one. Number two is that I'm feeling much more like reasonable facsimile of a human today. There's not much to report today as yet, because I did very, very little yesterday. The one important thing I ran across is a vulnerability in PHP 4.3.0 and earlier - go read this - then update your systems if that's appropriate.

I broke through the ice/slush berm and cleared a new path from our driveway to the road yesterday morning. Then Marcia and I went to the store and restocked, as well as picking up a couple of prescriptions. By early afternoon, I was trying to read some on PHP in one of my books on the Safari site. The problem is that taken individually, re-read over and over again, the words just didn't make any sense. So I took a nap, about four hours worth, for perhaps the third time in the last five years. I'm really generally not a napping type, so when I do, I really need it, neh?

On to work today to rebuild a Red Hat box, and install DB2 / WebSphere on it. Hope your day goes well, too - I'll close with some good news from Holden...

From: Holden Aust
Subject: Thompson's Basic Linux Desktop now available from....
Date: Thu, 20 Feb 2003 00:14:04 +0000

Brian,

Excuse me if I've sent this to you twice - I was so pleased to see this that I've sent it out to quite a few people and I couldn't remember if I'd already sent it to you.

In January one of the online Linux columnists predicted that sometime this year one of the major U.S. PC manufacturers would offer Linux desktop PCs. You could infer that he thought this would probably happen sometime late in the year, perhaps in the Fall or near Christmas.

But look what I found on the HP/Compaq website:

" Are you interested in Linux desktop solutions?"

{This first link on the Compaq site}

When you follow that link, you get to this page:

{This second link on the Compaq site}

and there's a "Buy Online" button at that page that takes you to:

{This third link on the Compaq site}

where you discover you can buy a very nice Compaq Linux desktop which is practically based on Bob Thompson's Asus/Nvidia "Basic System" for $464. The $464 system is based on a Athlon XP 2000+ (upgradeable to a 2600+ for $90) with 256 Meg of DDR RAM and a 20G 7200 rpm HD (upgrade to a 40G for $40 or an 80G for $80), Ethernet NIC, etc.

The machine comes with Mandrake, but is certified to for Red Hat and SuSE, as well.

So, now, in addition to the Microtel PCs from Walmart and Sam's Club, you can get a "Compaq-badged" Thompson "Basic Linux System".

Pass the word! Tell any of your customers that might be interested, see if you can get one to review for Linux Muse, etc.

      --- Holden

Good morning. A moderately successful day yesterday - I did a clean reinstall of RH 7.3 on a large bit of Dell hardware, then installed DB2 and WebSphere Application Server, as well as a fix-pack for that. It's an ... interesting process, harder than it should be. But I think it's close to being correctly implemented. We'll call in the big guns to check out the install and make sure all the twiddly bits are in their proper slots.

An SSL vulnerability was announced yesterday, and the way in which it was written up was simply atrocious. The announcement was explicitly stated to be a failure of the protocol, not of any one implementation. That's not true! It was a "simple" timing attack requiring an active man-in-the-middle, spoofing both ends and analyzing error codes based on return times to decipher a password. This doesn't work if the password isn't flying back and forth like a banshee, and the OpenSSL guys have it patched already. See this page for actual details.

Webmail implementations are really what's vulnerable here, since they use passwords so frequently. Ecommerce and most B-to-B stuff involves a single login per site, per usage. This doesn't mean that you shouldn't patch or upgrade - that's really important. But there was either shoddy paper-writing or ultra-shoddy reportage on this one.

I'm late already, so I'll leave you with this, sent to my by my friend and fellow daynutter, Svenson:

When advised that France had announced it would not assist, become allied with or otherwise support the US in any war on Iraq, former US Presidential candidate Ross Perot reportedly said: "Having to go to war without France is sorta like having to go deer hunting without an accordion".

Drop in on my better half... Mon    Tues    Wed    Thu    Fri    SATURDAY    Sun   
February 22, 2003 -    Updates at 0730 and 1400

Good morning and welcome to the new design. Well, a partial new design. I've re-tweaked the logo Yin-Yang ball more to my satisfaction, and lightened up the top-end of the page just a bit. I've been at this for a couple of days now. I'm pretty pleased with the result. Content is king - less foo-foo design. (But that one was fun to do.)

The tool used? The Gimp, of course. Now I need to go hop in the shower, and get out to tank up Marcia's truck before her day's errands, of which she has a number. Then I'll be back here for more of an update. In the meantime, if you haven't been paying attention, Matt Beland's Rearview Mirror site has been the recent recipient of some serious attention from both Matt and Keri. Go check it out!


1400 - Hi. I'm back. I've been a busy beaver. That dusty old tome, Brian and Tom's Linux Book, has been moved into it's own sub-tree on the server, out from under the pernicious influence of these pages. And at Greg's repeated prompting, the Search facilities on this site and in the book are now separated. That is, when you run a search on the book's site, you only get results from inside the book tree. That makes references to commands like lsof, for example, much easier to find.

The downside of this move is the literally hundreds of links that worked when the book tree was here needed to get finely fettled all over again, and it's much harder to find when there's about 7 major variations on the reference, and a few minor ones. It would be easy if only I hadn't just referred to it in the text as BTLB so very often. Oh, well, I think it's all fixed up now. The first round I did with Bluefish, and that worked great, but bogged down pretty heavily when more than 50 files were open at once. Greg suggested that I use Jedit instead. After a few false starts, Jedit worked just fine, thanks. And thanks to Greg.

Now I've got some favor-returning to do by figuring out how to pin packages in Gentoo, after surveying the back yard for drainage issues. See you around.

Richard Feynman 1918-1988

Mon    Tues    Wed    Thu    Fri    Sat    SUNDAY   
February 23, 2003 -    Updates at 0910

Good morning. Last night we had a lovely supper at the Fish Market in Old Town Alexandria, with Jack, Trudy, Mickey, Lydia and Tom. Yep, that Jack and Trudy, out from the West Coast for an IEEE meeting in the District. We ate well and jabbered away the evening. The good news was that, even though we took 3 - 4 inches of rain yesterday, our route wasn't flooded, and the rain had fairly well stopped by evening. There was some really thick fog in it's place.

So, what do you think of the new layout? Dan Bowman implied that I was trying to give him a stroke - he figured something was wrong with his monitor or system (because most of the difference is in colours, right?). Then there's the little web button at the upper right of each day. Mostly those will promote various things I'm interested in, like Marcia and LinuxMuse and the EFF, for instance. But Sunday's spot I'll reserve for some individual or another that I think deserves special attention. And these won't necessarily change from week to week, but as I find new (or old) and interesting people to link to.

This week, I'm pointing at one of the main sites in the Richard Feynman webring. I've always had a soft spot in my psyche for physics and physicists - I'll read physics texts for fun. And of the many, Dick Feynman always struck me as one who managed to maintain the best balance between real life and a life of mind that I can barely envisage. Bright, bright, bright, but down to earth, accessible, and one of those people that I'm so sorry that I never had a chance to met. He's written a lot, both technical and autobiographical. You can and should certainly read the latter lot - such titles as Surely You're Joking, Mr. Feynman! and What Do YOU Care What Other People Think?! Surpisingly, to most people anyway, the physics is also fairly accessible - the maths are there, but Prof. Feynman manages to convey much information without requiring all of the mathematical background that a deep understanding requires.


Now it's time to get ready for the Sunday shopping, as fresh rain clouds sweep in from the west. Following that, we're supposed to have high gusting winds, and continued dropping temperatures, down to the low 30's by day's end. I hope your day is well. Take care!

Visit the rest of the DAYNOTES GANG, a collection of bright minds and sharp wits. Really, I don't know why they tolerate me <grin>. My personal inspiration for these pages is Dr. Jerry Pournelle. I am also indebted to Bob Thompson and Tom Syroid for their patience, guidance and feedback. Of course, I am sustained by and beholden to my lovely wife, Marcia. You can find her online too, at http://www.dutchgirl.net/. Thanks for dropping by.
