This morning I upgraded the mail servers at work. They were down for maybe two seconds each. I doubt anyone even noticed.

If you’re used to installing software on Windows, you probably think I’m kidding. Didn’t I have to shut the service down before installing the upgrade? Didn’t I have to reboot when it was done? Nope!

The reason you have to go through all that trouble when you install something on Windows is that it won’t let you change files that are in use. So you can’t install the new Exchange without closing down the old one. And some files aren’t completely closed until you shut down Windows.

On Linux (and possibly all Unix-like systems), if you delete or replace an open file, the system hangs onto it until the program using it is done. So if you need to upgrade Sendmail, you can go through the entire process while the old Sendmail is still running, then tell it to restart the service once it’s ready.

It’s not quite zero, but it’s close!

About a year ago, I posted recommendations for Girl Genius, Fables, and Halo and Sprocket. Now I’d like to recommend a few more.

[Cover of Planetary #20]Planetary, by Warren Ellis and John Cassiday. The premise of Planetary is “archaeologists of the impossible.” Elijah Snow, Jakita Wagner and The Drummer are the field team for Planetary, an organization devoted to uncovering the secret history of their world. Each issue focuses on a different genre or archetype. There’s a Godzilla issue early on, there’s a Vertigo issue, one focuses on Hong Kong action films, and the latest is reminiscent of Rendezvous with Rama. Along the way, Planetary has uncovered a series of conspiracies — some positive, such as the Pulp Heroes of the 1930s, and others malicious, such as the mysterious Four (a twisted analogue of the Fantastic Four) who may be the most powerful people on the planet — if they’re still human. After a long absence, the series is now being published every two or three months. It’s expected to run around 25 issues, although it could take longer to wrap up the story. The first 18 issues and several specials are collected in four graphic novels. (Bimonthly/quarterly from DC/Wildstorm.)

[Cover of Fallen Angel collection #1]Fallen Angel, by Peter David, David Lopez and Fernando Blanco. The fictional Louisiana town of Bete Noire is a magnet for strangeness, ruled by the enigmatic Magistrate Juris during the day and protected by the equally enigmatic Fallen Angel by night. But nothing is as it seems. Is the Fallen Angel a heroine, or just a loose cannon? The main focus of the series is moral ambiguity and duality. Can you map “order” and “chaos” to “good” and “evil?” What happens when a force for good turns out to be sinister, or when someone once evil seems benign? Or when someone uses cruel methods to achieve a noble goal? The first few issues have been collected as a graphic novel. Suggested for mature readers – there’s usually violence and sometimes sex. (Monthly from DC Comics)

[Cover of Powers volume 2 #1]Powers, by Brian Michael Bendis and Mike Avon Oeming. Bendis is known for his crime fiction, and that’s the focus of Powers. The book follows homicide detectives Christian Walker and Deena Pilgrim as they investigate the deaths of super-heroes. Up until recently, their world was one where super-heroes were the A-list celebrities everyone followed, and the Powers world is as full of lawsuits, grudges, politics and sex scandals as Hollywood. That was volume one. Things have changed: after a particularly powerful hero went mad and rained destruction across the globe, world leaders have declared all powers illegal. Volume two picked up last month with the city trapped in a gang war between super-villains — with no heroes in sight. The first series has been collected in six graphic novels, with one more yet to be published. Another mature readers title – there is sometimes very graphic violence and sex, despite the cartoony style. And if you’re at all sensitive, don’t read the letters column! (Monthly, previously from Image Comics and now at Marvel/Icon.)

I am posting this from out on our patio. We ended up getting a Netgear wireless router that has its own built-in 4-port 10/100 switch and will hook directly into our DSL connection. What does this mean?

  • It adds wireless capability.
  • It can replace our hub.
  • It can replace our router.
  • We don’t need to find any more outlets or power strips. In fact, the end result is we’ve freed up an outlet.
  • We don’t need to buy wireless cards for the computers we already have.

The AirPort Express looked nice, mainly for AirTunes, but we would have had to put it in the other room with the stereo anyway. And besides, none of Apple’s Airport stations have more than one LAN port – the assumption is you’re either going all-wireless or you’ve already got equipment for your wired systems.

A few weeks ago I noticed that our network hub was getting disturbingly hot, so I started turning off the power strip when we weren’t home. After returning from San Diego, the first time we turned the computers back on, the hub started buzzing. However, it stopped after a few seconds.

So I should have thought of the hub immediately when the network started acting up today.

I had been on and off the computer and the net all morning with no noticeable problems, and Katie had been on for just a few minutes when it stopped loading websites. Continue reading

Yesterday I went to two comics stores looking for issue #2 of Powers volume 2, which hit store shelves on Wednesday. Both had already sold out.

Today I tried a third store. They had a stack of at least 20, and that was just on the shelf. Who knows whether they had more in the back?

Of course, this store tends to carry both a larger selection and a larger inventory than the others. If I’m looking for back issues or anything esoteric, that’s my first stop. The others — well, the one I normally go to (which is near where I work, so I can drop in on my lunch hour) has a small collection of mostly recent back issues, but much of the store is given over to D&D and Warhammer. The one I tried yesterday evening (since I had a better chance of getting there before closing) is very small, and I have no idea what they do with their back stock, because I’m fairly certain it’s not in the store. But they have lots of graphic novels, anime, and manga — and the best thing is that they rent out graphic novels as if they were videos. That’s how I discovered Powers, actually — one of their clerks recommended it to me and I rented the first few collections, then started buying them.

What I’m getting at is that store #1 and store #2 seem to be ordering the number of books they expect to sell and no more, while store #3 seems to plan on keeping things around so that people can come in, pick up issue #4, and look for issues #1-3, and actually buy them.

Either that, or stores #1 and #2 mainly get customers in on the day new comics arrive, and store #3 gets more of its customers on the weekend.

So Apple is ticked off at Real’s reverse-engineering to let people buy music from Real and play it on an iPod. Apple has threatened DMCA sanctions and all but promised to deliberately break it in the next software update.

Excuse me? In general I like Apple, but their insistence on locking the iPod to iTunes and iTunes alone is short-sighted. When people hacked up a way to use an iPod on Windows, they first licensed the software, then wrote iTunes for Windows. iPod sales have tripled to the point where they may soon outsell Macintoshes. This could never have happened if Apple had kept the iPod Mac-specific.

I’m reminded of the many times Microsoft has altered its file-sharing protocol to break compatibility with Samba, the package that allows Linux, BSD, and now Mac OS X to connect to Windows networks.

The classic analogy is getting a car that can only run on certain roads. So someone’s found a way to let the iPod drive some different roads. But Apple still sells as many iPods. They might even sell more (as when it gained Windows compatibility). Why the accusations of hacking, why the legal threats, and why the determination to keep the iPod locked to their own roads?

More “You sent a virus!” garbage going around. It’s gotten to the point where I don’t even look at most delivery failure notices, which means I could easily miss errors about mail I really did send.

I got ticked off enough this time that I wrote back to the return address on the warning, matching the tone and structure of their message as closely as possible:

An invalid virus notice was found in an Email message you sent. Your Email scanner recognized a virus as W32/MyDoom-O but did not take into account the fact that this virus always uses a fake sender address.

Please update your virus scanner or contact your IT support personnel as soon as possible as you are sending bogus virus warnings to third parties whose systems are not infected with the virus. This runs the risk of causing unnecessary concern among the less tech-savvy (and extra calls to tech support about the nonexistant virus they fear they have). I would recommend reading up on the phrase “crying wolf” as well.
