bounce

No, not the fabric softener. The church I grew up in in Albany NY (Albany Baptist) has been trying to move out of their old building for several years, and finally got a sale on their current facilities to be able to buy a new building. However, before they could move, they had to have their closing on the old building.

It had been waiting in semi-limbo for a couple weeks, but a week ago Saturday the officers got a call saying that the buyers wanted to close the following Thursday, the 8th.

I decided Monday evening that I was going to head to Albany for the last prayer meeting in the old building. It’s the only reason I went up, and I knew it was going to be a very long, tiring trip. Fortunately, a couple friends, one of whom grew up in Albany the first half of her life, were able to come along to help split the driving.

Last Tuesday a little before 7p, we left Mebane and started driving. Got into Cohoes a little after 7a Wednesday morning, crashed for a bit, then popped around the capital district for a few hours before heading to church that night. After the service, we hung around for a while to say hi and visit for a couple hours with folks we know there, then got back in the car and headed south.

Unfortunately, we had a bit of a hiccup going south and lost about 1.5 hours of travel time due to my not giving full enough directions to my friend driving while I took a nap, but we made it back to Mebane safe (and tired) Thursday afternoon.

All told, we were gone for 46 hours, and spent all but 16 of those hours in the car (either sleeping at a rest stop or driving).

While not the most ambitious bounce trip I’ve ever pulled off, it was still fun. If you know me, and would like to know more about the trip, feel free to leave a message in the comments.

cirque du randall’s island

On Friday, 26 May, my parents, sister, and I descended onto Randall’s Island from the Triborough Bridge to see Cirque du Soleil’s Corteo production.

We’ve enjoyed watching Cirque du Soleil’s productions for years on TV, but had never had a good opportunity to see them in person. CdS is a circus in the European tradition rather than the American one, so there are no animals – just clowns and acrobatics. The entire show is actually a story set to music and gymnastics rather than a spectacle of just noise and juggling atop elephants.

One of the cool things about the Corteo production was that it was done ‘in the round’, so the audience sat all around the stage, and the show is viewed from every side. It was also done in a tent – which I will be the first to admit I didn’t know was done anymore.

Being in a tent in New York City with a few hundred other people on Memorial Day weekend wouldn’t normally sound like an enjoyable experience, but apparently tent design and contruction has improved since the early days of PT Barnum: Cirque du Soleil’s tent has an integral HVAC system attached to it made from the same material with a slew of holes punched-out. It is quite effective – enough so that just sitting still under the vents could make a body chilly.

Tickets may seem a bit pricey (ours were ~$50 each), but it is well worth it. They’ll be in NYC until the 25th of June, and have other tour dates listed on their web site. I strongly recommend getting out to see the show if you can.

virtually speaking

I’ve gotten very interested in virtualization technology recently. There’s a high probability I will be working with VMware this summer, and several of my websites (including this one) run on a virtual private server provided by Tektonic, running CentOS 3 through Virtuozzo.

Virtualization is a fascinating concept. Instead of needing gobs of physical servers, by running operating systems through a virtualization layer, several servers can be run off one physical piece of hardware. With several options available – including Xen, VMware, Virtuozzo, User-Mode Linux, Virtual Server – deciding on a particular route is difficult at best. Depending on your budget, actual server OS requirements, and available physical hardware, all of the above may end up being viable options.

Because several guest operating systems will be running inside or on top of the host virtualizer, underlying hardware generally has to be pretty hefty. However, some of the available virtualization options will allow as many as 100 guest operating environments – so installing just a few high-end servers can replace potentially dozens or hundreds of pieces of hardware.

Solutions such as the new edition of VMware ESX Server are actually smart enough to automatically shift virtual instances from one piece of physical hardware to another based on server load, or in the event of hardware problems.

User-Mode Linux, aka UML, is actually Linux ported to run on an abstract hardware standard implemented in Linux – so it’s Linux ported to run on itself. Now that hurts to think about.

As I get more personal experience with virtualization technology, I’m sure I’ll be writing more about it.

on open-source

I am a huge fan of FLOSS: free/libre open-source software. My website runs on CentOS Linux, one of my home machines runs Kubuntu (you Gnome users are lost), I use emacs (down you vi fiends!), Anti-Vir, Crimson Editor, Firefox, Apache, PHP, BitTorrent, Python, WordPress, and so many more I can’t count them all.

I have often thought about how/whether I can contribute to these projects. The ones I use are all worthy of support, and I suspect many more would be if they got some momentum behind them. And I don’t have the time, skill, desire, or energy to try to pitch-in on bug fixes, feature adds, porting, or any of the other thousand and one things these projects ask for.

I contribute by linking back to those projects. I tell my friends and family about them, and try to get them to use them and spread the love, so to speak. On a few projects I have contributed to their donations page. And I contribute to those projects by releasing libraries of my own.

Code I’ve written, mostly in the forms of low-level data structures and little utility functions, may not be very sexy, or even ever get used, but I put it out there for folks to grab.

I love the determination and drive shown by those pushing forward on FLOSS projects, and I wish I could contribute more. Maybe some day I’ll be able to, but for now, thanks for your efforts.

do not attack iran – and see what happens

The International Herald Tribune had an editorial recently on Iran and the current United States’ administration’s use of preemptive strikes. [original story]

In general, I would say that it is wrong to start wars. However, the IHT article seems to go along well with the post I wrote about nuclear proliferation and the dangers of totalitarian rulers. Or rather, it goes directly against what I said. All of the reasons to not execute a preemptive strike against Iran’s nuclear capability, and its alliance with terrorists, are old and tired.

The author is apparently unfamiliar with US law. Zbigniew Brzezinski writes, “if undertaken without formal Congressional declaration, it would be unconstitutional and merit the impeachment of the President.” It is an established fact that periods of armed conflict under a set number of days, or directly tied to iminent threats are not covered under US law regarding the declaration of War on the part of Congress. He also writes, “if undertaken without the sanction of the UN Security Council either alone by the United States or in complicity with Israel, it would stamp the perpetrator(s) as an international outlaw(s).” This is not relevant. The United States does not answer to the United Nations, it answers to its own laws and treaties it has signed. If the United Nations will not undertake to follow its own rules, member states may, can, should, and will.

The United States, along with many allied countries, invaded Iraq to depose Saddam Hussein. Whether or not they found any weapons of mass destruction is irrelevant for the time being – Saddam had consistently defied international bodies, and the US merely stood up for what the UN claimed to promote.

Those in power have a responsibility to do good for their people – and for those others whom they can. When a leader, whether it is Adolf Hitler, or Slobodan Milosovic, or Saddam Hussein, oppresses his own people to the point of killing them merely becase they displease him, he is no longer fit to rule.

The IHT article goes on to list volatility in the energy market, international dislike, increased terror acts, and increased muslim fundamentalism as potential problems to such an act. Iran’s potential to ‘hand over the bomb’ to a terrorist group is not in doubt. And that terrorist wouldn’t likely use it on them. They would be far more likely to use it on a prominent target in the west.

In an ideal scenario, Iran would capitulate to economic sanctions, and diplomatic avenues. But we live in a far from ideal world.

Is the United States perfect? By no means. Neither is any other country. However as a nation, we have been blessed with power, influence, and backbone. I don’t want it to come to the point of needing to make a strike against Iran to hold them accountable for atrocities they are and have been complicit with. But if no one else will take a stand, I pray we do.

the strip club

Obviously I have too much free time in my head. Yesterday, while celebrating the end of my rather blasé database course, my friend Matt and I decided to go hit up Cook Out for milkshakes – and yes, I got my all-time favorite peanut butter mint 🙂 – and it dawned on us, through some unknown sequence of conversation, that a perfect name for a furniture refinishing business would be ‘The Strip Club’.

That’s right, you can bring us your old, tired wood tables, chairs, and dressers, and we’ll smooth them down, and polish them up. No blowing through any jobs – we’ll do our work by hand. Is your bookcase taking a beating? Let us scrape off that old finish and massage-in the new. You can even bring in your buffet in the buff, and we’ll wax it for you.

Alright, I’ll stop now, but it was fun while it lasted :).

the good, the bad, and the ugly

I have had many teachers through the course of my life, and expect to have many more as time goes on. But something I have been able to identify very quickly about every teacher I’ve ever had, are their strengths and weaknesses of teaching the topic at hand.

My favorite college professor is Dale Bryant, the long-time computer science teacher at Hudson Valley Community College. Dale’s approach to teaching was fun, energetic, and engaging. And he was under the impression that if you wanted to learn, any way you could was great. If the way he discussed and presented material didn’t click with you, he didn’t mind if you went searching elsewhere for an explanation that worked for you. This happened many times with my friend John Deignan who would routinely ask me questions about programming concepts in general: object-oriented issues, library questions, the ‘how does this work’, and the ‘why do it this way instead of that way’ questions.

For John, Dale’s explanation of template classes and functions in C++ didn’t gel. But with both more time available, and an understanding of his personality, I was able to come up with a metaphor that worked for him.

I have been fortunate to have very few teachers who were bad, and even fewer who were ugly. One of my first-semester instructors at HVCC, in trying to teach us Excel and Access discovered that she didn’t know how to do the assignments in the book. And her idea of teaching was to ask questions of the class, and then practically shout the answer out if no one spoke up within about 10 seconds.

Contrast that approach with my calculus teacher who had (either on his own, or discovered) come up with little songs and ditties to help us remember how to do derivatives – including his famous quotient derivative rule song to the tune of “If you’re happy and you know it”. Or my discrete structures professor who would crack jokes about having an 8AM class full of computer science folks who don’t start cogitating until lunch time.

Unfortunately, this semester I have had the experience of having another bad teacher. The first day of class sounded promising, and I was actually looking forward to his approach, but he quickly showed an inability to teach. He may know the material, and be able to perform the tasks required in database consulting and administration, but he can’t teach it. I had a leg-up on the rest of the class in having taken a couple database classes in the past, and of designing and implementing several on my own for either other classes, or personal projects. But when even the folks who have been to every class aren’t “getting it” (not just those who have missed half the classes), I have to wonder whether or not he knows what he’s doing.

The common trait across all the good teachers I’ve had has been interest in the subject. Whether it’s literature, composition, programming, terrorism, or something else, good teachers are interested in the material. The common trait I’ve seen across those few excellent teachers I’ve had has been the ability to connect with students, and not hold themselves above the student, but rather to remember what it’s like to not know yet.

The bad and ugly teachers I’ve had have shared something too, they’ve all been unable to communicate – and they’ve all forgotten what it’s like to not know. Some of them haven’t known the material, or have not cared. But they’ve all been unable to connect with their students.

I don’t know how good teachers appear. It might be by birth, upbringing, discipline, predisposition, personality, or because they had a great teacher who inspired them. Maybe it’s a combination of all of those factors. To those who are just blasé, I hope you can become better. To you who plain suck – please quit: you’re doing more harm than good.

But to those great teachers out there, thank you for your efforts – we notice.
