I care about performance because I have a few hundred thousand files on servers that 100 employees need to access. Caching will only get you so far when you have a lot of people going after a lot of files through out the day. Since we have the choice of which fs to use, it is nice to have more info to pick between them.
There is more to this world than home users and databases.
A quick look at the reviewer's web site and a glance at Sybex's internal contacts documents shows no obvious link. He didn't write the book and he hasn't done any work for Sybex in that last few years.
Is he related to somebody at Sybex? Who knows?
Is he dating somebody at Sybex? I have no idea; I don't get the good gossip at work.
Me? I work for Sybex. I'm the Director of Information Services. I have little to do with book creation, but I wouldn't mind if you bought a couple of our books.:)
The NWS's automated weather channel broadcasts use a new technology this year. The changeas quite a big deal in the marine communities, wear people listen to these voices every day. The new voices are pretty darn good.
You are confusing light and sound.

Depth perception is a function of the angle of the eyeballs away from parallel. The closer an object is, the more the eye is turned in. That's why depth perception works very well up close (relatively large angular change for a small distance change) and depth perception doesn't work well for distances. Beyond 20 feet (maybe yards I forget) the mind uses other cues to decide distance.
Once you have distance simluation, 3D is just shading.
Big thumbs up for this product. As an added bonus, you can also scan ftp and http traffic, so you have more points of entry covered.
We've used the product under RH for a few years and it has been very stable. Performance is good even on a low end machine (400Mh). The license is for a protected number of machines/user, so you can deploy multiple scanners to load balance.
We have a scanner in front of our co-located mail server, and a scanner in front of our on-site mail server. We do a lot of huge ftp work, so we setup a 3rd machine just to act as an ftp proxy so the web surfing doesn't get bogged down when the occassional 50M zip file is scanned.
First, if she WANTS one, get her one. This isn't about you.
When we got married I spent evey penny I had on a small diamond. I don't even know how big it is. Size didn't matter then, doesn't matter now.
From time to time my wife mentions a new ring. We have more money now and I always tell her that she can have whatever she is comfortable buying. But, she doesn't really want a new ring.
Buy something that really is a couple thing - a tandem bicycle!
Mechanical watches are made by dozens of companies today, including Swiss
Rolex,
Omega,
IWC and dozens of others, even Swatch.
Even Seiko
makes mechanicals (although mostly for the Asian market). The Chinese make a bunch of cheap movements and the Russian company Poljot makes an interesting line of affordable watches.
Accuracy ranges from +/- 1 second per day on high-end Swiss watches to +/- 20 seconds per day on the Russians. In general anything under +/- 6 seconds per day is considered good. However, there can be a great deal of variation from watch to watch. Rolex, Omega and other mass market companies do little or no hand work in their mass market lines. When you get to a company link JLC, and others, every watch gets some hand fit and finish.
However, none of them can be wound only once per month. Most have about a 40 hour power reserve. A few have an 8 day reserve (notably an IWC,
and an Eberhard. Of course just about every company offers an automatic watch that is wound by the movement of the wrist through out the day. Those watches should "never" need winding if worn every day or two.
Everything you ever wanted to know about mechanical watches can be found at Timezone. Be forewarned, most of these guys think of watches under about $5,000 as "mid priced".
You really should be asking a group of sailors. They will for sure be able to tell you what does and doesn't work.
We aren't talking about computing in the cockpit, so don't get too crazy about waterproof. Lots of people have laptops at their nav station and get e-mail via shortwave radio, so this isn't new ground. The trick is to secure the computer when underway.
I'm not a big fan of laptops, so I'd look at this one. Small and too the point without paying a huge mark up for a laptop.
Vintage watches are by far the most affordable. There is a dizzying array of them out there.
For new models, Invict, Revue-Thommen, Glycine and Poljot are the most common. Poljots are Russian and are regarded as true bargins. There are about half a dozen places to buy them on the net.
The thing to remember about a mechanical watch is that they have a life span measured in decades, with proper maintenance. Don't think of them as disposable and you can justify a much more expensive one than you otherwise might consider.
NASA did not send astronauts to the moon with Breitlings.
The offical issue watch was an Omega Speedmaster. There is some indication that non-offical Hamiltons may have also gone to the moon. Vintage Speedmasters cost about $2,000. A new one, with essentially the same look, but a newer movement is bit less. These watches are hand wound chronographs.
The current NASA issue is either a G-Shock or an Omega Speedmaster X-33. Both use a quartz movement. Official NASA photos show astronauts wearing both.
Backing to a stagging array and then moving to tape is a great idea. Backing up to HD means you only get to keep the last couple of back ups. The reason to use tape is to go way back in time. With a good grand father-father-son rotation, you can keep a lot of history with a reasonable amount of tapes.
I have backups dating to my first week at this company several years ago. I can raise the dead from almost any 2 week checkpoint since then. I have had requests for e-mail that has been gone for 6 months and documents that have gone for more than 18 months.
It makes you look really good to just smile a friendly smile when somebody asks sheepishly, "I need a file from an employee who quit last Easter. I'm not really sure what it was called, but I think I know where it was on the network. Can you help me?"
While the dream of a single password is a cool idea, I have concerns about how secure that is.
Sure, you can probably get LDAP to do it all, but should you? Picture an environment that is a mix of ftp and ssh. You use SSH, because we all know telnet is insecure. If you have the same password on both ftp and SSH, you have given up a major layer of security. If you want to limit the number of passwords, you should, at a minimum, probably have one for "more secure" systems and one for "less secure". Anything that transmits in plain text, like stock telnet, ftp and POP, should be separate from anything that transmits encrypted data, like SSH and HTTPS.
Defense in depth encourages multiple passwords. Strong security always seems to be at odds with ease of use. You don't have the same root password on all your boxes, do you?
Why do you NEED to do this? What's the business case for this change? How much will you spend re-training your staff? What isn't Netware doing for your now?
If you are using Netware, the change (IPX to SMB) to 10,000+ dekstops is going to crush your staff. If you are used to using lots of directory specific permissions, will SAMBA support more than just World/Group/Owner R/W/X. Netware has very granular permissions that you might not want to give up.
Don't get me wrong. For many application servers Linux is great. We are moving away from MS to Linux everywhere that the required task can be done well on Linux. Don't do what many MS shops do and try to use one tool for all tasks. Netware is the gold standard for file and print services. Before you give that up, you better have a good reason.
How is SAMBA's support for Macintosh machines?
A quick pop over to APC shows that a Smart-UPS 1000 XL + (1)UXBP24 Battery Unit will have similar performance and only cost $1,600.
Can you say, "Not ready for prime time."?
Take a look at Sawmill. It is a first rate log analyzer that includes path analysis. It runs on almost any platform and out of the box understands dozens of log formats. It is very flexible, so you should be able to tweak it for any specific fields you want in your reporting.
Sawmill, by Flowerfire is pretty cool. It understand virtually every log you imagine. It'll run as a cgi, via cli or as a stand alone web server. There is a version for many different platforms.
With the web interface, the Marketing group can do their own drill down and queries, so I can dosome real work.
Performance is good.
I think of it as the program that WebTrends wished it was. Get the eval version and take if for a spin.
