The extreme case of projecting in to the corner is accounted for in the example images on the linked page. I'm sure there is some distortion or focus problems, as the low-res images don't give full detail. Still, the corner selected contains blemishes as well, and the image looks pretty good. Sure the designer painstakingly selected images, but the corner image and curtain image are quite impressive.
Parent is insightful/informative? Come on moderators. RTFA! The product uses a light pattern to calibrate the distortions of the surface, then adjust the areas of the image to compensate for varying colors and distances from the lense. Examples of surfaces and images projected on those surfaces are provided.
From the linked page: Our smart projectors combine camera feedback with structured light projection to gain information about the screen surface and the environment. The calibration of such a device is fast, fully automatic and robust, and the correction of video signals can be achieved in real-time.
When the power goes out for the eastern side of north america I prefer to be able to still reach people. Cell phones and wireless phones just can't do that.
I have a wireless phone with a base that contains a charging bay for a second handset battery. If this battery is fully charged and power is lost, the battery will allow phone calls to continue for up to 2.5 hours of talk time. On a recent sunny afternoon a construction accident (remember, call before you dig!) killed the power while I was on the phone on my balcony. I never noticed until I saw all of my appliances with clocks needed reset. I also have a wired phone just in case.
Important stats to remember: the North American wired telephone network has uptime of 99.999%. Cellular telephone networks have uptime averages of 98%. Also, most cells can only support a maximum of 32 calls (depends on the technology). Exceed that and expect dropped calls, no service errors, or "all circuits are busy" errors. If the power fails over your entire cell, expect others on your network to be relying on their cell phone too. If the power outage is extended, expect the backup power source for the cell towers to fail. Central offices for land lines are not as wide-spread and thus it's easier to deliver additional fuel for backup generators.
I have an AT&T 5840 phone that uses 5.8GHz but if you read the fine print in the specifications, it also uses 2.4GHz:
RF Frequency Band (Handset to base): 2400 MHz - 2483.5 MHz
RF Frequency Band (Base to handset): 5725 MHz - 5850 MHz
All 802.11b/g devices use channels within 2412 MHz - 2483.5 MHz, so there is quite a bit of overlap there. When shopping around, I noticed that many 5.8 GHz phones actually use 2.4 GHz as well. In my limited use of 802.11b in the vicinity of this phone, I noticed no interference, but ymmv.
If you read the article, you'll see that this product is aimed at offices and campuses where wired ethernet ports are plenty but users may break policy and install an unauthorized wireless access point. Most users who do this are likely to keep default settings including no encryption.
They are really great dentists, so it's mostly worth it. It also helps that they are family friends so I get most things insurance doesn't cover for free.
No, you'll find that sheet music is indeed copywritten and protected like other intellectual property. A major portion of music and band departments' budgets at schools goes towards sheet music.
The problem is that I can't help thinking that someone out there might like a Sony NEWS, or an old Sun SPARCstation with a HUGE (but small in capacity) SCSI hard drive!:)
I have a few old SPARCstations (a 2 and a Classic). They rarely sell on eBay and their value is less than the cost of shipping. Their ratio of power consumption to performance is poor compared to modern devices. No one wants these until there are so few left that they are museum peices.
Without having to spend their money on propritary closed source software, people will have more money to spend on other things - resulting in a net gain for any society that uses Free software.
The irony about this statement is that Microsoft has incorporated open source software in several of their products, such as their command line network utilities. The BSD license even lets Microsoft save money by not having to reinvent the wheel, allowing them to spend more money on other software features. This, in turn, lowers the price of their software or increase margins. Lower price software of course leaves more money for consumers and businesses to spend on other things, from payroll to goods requiring workers to manufacturer or create.
unless they are a kiosk inside another retailer (Safeway or Barnes & Noble for example.
Those are also not franchises. They just sell Starbucks coffee products exclusively, but are owned by the parent store. Starbucks only gets the profits from volume sales of coffee to these resellers, just like selling to a grocery story.
The article says winds reach 80mph (130km/h). I'm not sure it would be uniform loading, though a dome would still have an advantage if the stresses are uneven.
What market is currently being targetted by the OS X Servers?
Someone else mentioned life sciences. They also seek the K-12 Academic markets where it's hard to employ a full time network admin to set up Active Directory, Exchange Server, etc. The same applies for small businesses, those who are likely to prefer the idea of one server does all (or most) of the services they need, especially email and file sharing. Another big market (almost the cliche Apple niche) is the creative market, from media agencies to smaller publishers to design/creative departments at larger companies. Often these organizations don't employ a full time admin, leaving that to outside companies and a designated person within the group. In the case of a creative department within a larger company, they often have a disconnect between the rest of the company (being on Macs while the rest of the company is on PC, for example) along with different needs.
leading me to conclude it is a niche market
As Apple adds more features to OS X server, they hope to please their existing niches while making it apparent to others that they can easily configure a complex server without having to rely on Microsoft. They get the stability and security associated with open source plus the ease of use from Apple.
Hell, with the $3.6 BILLION Target's getting for marshall Fields, I wouldn't be surprised if Target bought Amazon.
Given Amazon's market capitalization of $20.98 Billion, I think that's a pretty silly idea. Target, for comparison, has a market cap of $40.60 Billion. It's kind of amusing, though, to see Target's P/E of 21.15 compared with Amazon's P/E of 143.49.
For example, Cox states in its End User Agreement that users cannot download more than 2 gigabytes a day or more than 30 gigabytes a month. Problem is that I don't think this is really implemented.
If I had the 15-25Mb connection, I'd gladly offer to test this limit.
Oh, but you do. First-class mail rates significantly subsidize the cost of bulk mail. The USPS knows better than to antagonize some of its largest customers. Ditto for the good folk at the RBOCs.
Actually, that is incorrect. First class is low volume and collected in many places. Bulk mailings are high volume and usually collected at either one location or several locations regionally (like national periodicals). Bulk mailings for the USPS must meet strict guidelines. The more guidelines a mailing meets, the cheaper it is per item. With magazines, for example, if the cover is approved by the USPS, it is cheaper than an unapproved periodical cover because it is easier for machines and letter carriers to read the address. Bulk mailings are cheaper because their collection is streamlined, they are sorted for further discounts, and they have lower priority than first class.
Given that the VW stereos from recent years (1999 and later) can control the PhatBox system, I imagine someone could make a hack to connect the iPod to the CD changer connector that is prewired in most of these Volkswagens. Hacks already exist to use just the audio connection. It is possible someone could make the stereo buttons control the iPod and display the current track name on the head unit. The only problem is that most Vokswagens have the harness in the trunk, which isn't as convenient as the glove box.
That works until everybody cries "anti-trust!" Damned if they do, damned if they don't. There's a lot of lightening up that needs to happen.
I agree for the most part. Microsoft bought Central Point Systems in the 1990s to integrate Scandisk and Central Point's antivirus scanner (msav) with DOS, but other file system checkers continued to work well and differentiate themselves. As long as Microsoft doesn't keep Symantec, McAfee, et al., from having access to APIs necessary for them to continue their own innovations in Virus Scanning, they will likely innovate features to make some users prefer to buy their product instead of buying Microsoft's. Remember, Microsoft will not be bundling it in with the OS. The problems come when Microsoft strong-arms OEMs to bundle it, especially if they use price pressure to encourage exclusivity (see also MSN vs. AOL, Windows Media vs. Real Player, etc.).
The users have varying level of backups, but the biggest issue is that no one can find the new blog now. The weblogs.com domain was integral to these blogs, much like blogger.com, typepad.com, etc. The weblogs were found at hostnames like booknotes.hammock.com, rex.weblogs.com, delphi.weblogs.com, etc. Users very much could have used an opportunity to say what their new URL was. Dave Winer decided that was too much work [MP3 audio post he made].
Another reason that SCSI drives perform better in RAID arrays is that SCSI permits out-of-order I/O request execution.
It also has great command queuing as part of the out of ourder command execution. Serial ATA supports Native Command Queuing, providing these features plus First Party DMA and Interrupt Aggregation. Hardware support is relatively new. Seagate was the first to make a drive that supported it. My understanding is that the majority of Serial ATA drives out there essentially have parallel IDE controllers with a Serial ATA converter.
Here is a great article from Intel on NCQ: PDFHTML.
IDE performs blocking I/O, so everything would have to wait until drive 3's read was complete. I don't know if this also applies to SATA.
Interrupt Aggregation and First Party DMA were designed to limit the effects of this. SCSI still has an advantage with its offloading controller though. I also understand that the maximum queue depth for commands on the SATA is 32, while it is 256 for SCSI.
As a Baltimore native, believe me, I have absolutely NO expectation of safety whenever I go downtown.
This should be an interesting experiment. To what extent will the citizens feel safer, and how much safer will they actually be? Most criminals don't expect to get caught when the commit a crime. So will criminals alter their behavior? Will (or can) they move beyond the reach of cameras? It isn't yes or no, black or white. Instead I think it will be an experiment to find where the balance is. What amount of privacy are citizens willing to give up for perceived and actual improvements in safety? I've been to other cities outside of the U.S. and never felt violated by their surveillence networks, but I can't imagine that American culture will react the same way as other cultures. I must admit that I am relieved this is happening in Baltimore, not my home city.
It's worth noting that as of OS X 10.3, Postfix has replaced Sendmail as the default MTA. NetBSD is integrating it in to the base install and letting the user decide between Sendmail or Postix, the default being neither is enabled at startup. Both use BIND 9 as their named by default, however.
This brings up the interesting debate of whether shared authenications systems are more secure or less secure. If you had only one password for all 6+ systems, you'd probably see much less reuse of old passwords. On the other hand, having someone's password could me access to 6 different systems on a variety of platforms.*
*It is idealistic to think that a single authentication system will be shoehorned in to every system used in many enterprises. More than likely at least some application will not be able to use the networked authentication for one reason or another.

The other question is, will the 5.8 interfere?

Or you could simply use wired networks.
