Umm, and exactly what do you mean by "Universally acclaimed?" Please be a dear to show us the list of articles written about this product that nobody outside of Slashdot has heard of.
While others have commented on the author's horribly bad grammar and style, I wonder what he means by getting better Google page rankings if you get people to bookmark your site? I'm consused. How can Google know if I bookmark a site?
I wrote that description when I created the AOLserver project on Source Forge. AOLserver really hasn't caught on and despite releasing 4.0 there isn't really much reason to use it. All of its cutting-edge benefits, like integrated database handling and in-process scripting, are now done better in Apache.
As for being the backbone of the "largest and busiest production environments" that is rapidly changing. They re-released the webmail system using some other software (definitely not AOLserver) and most of the outsourced projects aren't even done on Unix.
In my area (Verizon, VA, USA) they sell ISDN as a pseudo-DSL service called "iDSL." The product achieves 144 kbps up and down and about the same latency as a T1. It combines the ISDN A, B, and ISDN control channels together (64+64+14). The modems are horribly expensive--around $300 last time I asked, maybe because it has to deal with three channels at once(?). The service is (was) about $70/month. My area has since gone G.lite so iDSL is strongly discouraged in favor of regular consumer DSL which, after all the ATM encapsulation and tunnelling, is only moderately better than cable modems in terms of latency.

Thanks for playing, but I never said anything about "bars." I am talking about signal strength and quality of the signal. Interesting how you first say that bars do not correlate, yet you use "bars" to say how good your signals are on your various phones. Make up your mind.
Your other comments are valid and interesting.

Another poster mentioned a place that sells mobile phone repeaters which may address the problem originally asked. These are virtually the same as the repeaters used by very early analog cellular car phone handsets (the ones that passively transmit the signal through glass to an external antenna) but are specifically designed for both ~850 MHz and ~1900 MHz mobile phones. Most of these repeaters work with all GSM and CDMA providers in the USA, but most of those do not work with Nextel. I was thinking of getting one for my house. These are legal and will fit the bill the original poster asked.
One thing to be careful of. These repeaters always use omnidirectional antennas (not uniderectional Yagis). If you are a CDMA customer (Verizon and Sprint in the USA) the provider will shut you down if you use a Yagi. The principle of CDMA is that all phones are balanced to the same signal strength. CDMA phones all transmit on the same frequencies at the same time and the tower will command your phone to reduce signal if it drowns out other customers. If your phone reduces its signal but is still too strong, the Verizon "Can you hear me now?" guy will find you and shut you down.
GSM is more forgiving to Yagi users but they still do not like it.
Keep the omnidirectional antenna the repeater set came with and you won't get in trouble. The vendor the other poster mentioned sells repeaters that are not only approved by the mobile phone providers but are also used by the mobile phone providers.
Keep in mind that I'm not describing a picocell or microcell, merely a local mobile phone repeater unit.

I have mixed feelings about that. As with many new technologies the marketing oversells the technology so incredibly more than the existing or near-future technology can ever accomplish. Todays' mobile phone networks were designed as mobile phone networks. Now people are being told that yes, indeed, you can take your "mobile" phone and use it in your non-mobile dwelling.
The CEO of Verizon said this very thing earlier this spring. T-Mobile has been saying this all along and recognizes the practicality of mobile phones in dwellings (it does not work) and is rumored to offer a real solution that will really work.
I don't know about where you live and work but when I walk outside my mobile phone gets nearly 100% signal compared to 10-50% signal inside. This is the same with my T-Mobile, Verizon, Cingular handsets, and two out of three use different towers in the areas I live and work.

Umm, no, this device will not help you in the USA. Most GSM providers in the USA have GSM only in the ~1900 MHz range with some tiny amounts of GSM coverage in the ~850 MHz range. Cingular is desperately rushing to replace the analog cellular and digital TDMA networks in the ~850 MHz spectrum with GSM (their current phones already try to find a GSM signal there, but very few of them will work in analog, and only one of them will work in TDMA). Unfortunately for Cingular the FCC is mandating analog cellular to stay online at least until 2007 and TDMA to stay online even longer--its deadline recently extended to 2008.
T-Mobile has very localized ~850 MHz coverage in some markets where thousands of customers could get not service, like large residential areas and major highway interchanges. At least they're trying. This device you speak of won't work for T-Mobile, either.

T-Mobile has been rumored to offer in-home VoIP service in the fall of 2005. It wouldn't be legal for you to run your own "picocell" as the GSM frequencies are licensed, even in those picocells that the carriers deploy in malls and sporting events.
T-Mobile's rumored new service will utilize a new class of mobile phones which are GSM and WiFi hybrids. While you are away from home the handset works like a normal GSM phone. When you get home the handset switches to WiFi and connects calls using a wireless VoIP gateway that you connect to your high-speed internet connection. T-Mobile will bundle the hybrig GSM+WiFi mobile phone, the WiFi VoIP gateway device, and the VoIP service. To the mobile phone user the only thing they notice is that their T-Mobile phone works at home and they can finally drop that PSTN line.
This is in response to the overwhelming T-Mobile customers who tried to use number portability to switch their home phone numbers to T-Mobile and found that their mobile phone didn't work in their homes. Most of T-Mobile's spectrum is 1900 MHz which doesn't penetrate well into buildings. At the same time, T-Mobile (and the other carriers) were spending billions to acquire space in the 800 MHz spectrum to try to improve the situation but someone had the bright idea for T-Mobile to offer all-in-one GSM+VoIP service for much less money than building out their mobile GSM networks which already work really well outdoors.
I think it's a brilliant plan and it's much cheaper than giving everyone GSM repeaters at $500-$1200 per unit just so their mobile phones will work in the house (but never the basement)... of course the hybrid GSM+WiFi phone *will* work in the basement. It's simply brilliant.
so if youre smack dab in the middle of central Africa, theres NO way to communicate back except maybe long range ham radio.
Ahem. Inmarsat has been around for decades and covers all of Africa. There are local agents who can hook you up with rental Inmarsat briefcase-sized communications units. Inmarsat has also had fax, store-and-forward, as well as packet data for a long time and have in recent years been providing high-speed data, too.
This sounds like an early production version. My HT-488 arrived several months later than projected due to production problems with the early devices. Furthermore the firmware was withdrawn at http://www.grandstream.com/ for more upgrade work. I think they do a good job of standing behind their products. I also think they're pretty embarrassed by the BudgeTone line of phones, which are pretty bad, but the ATA devices are top-notch in my book.
Please do not confuse the phones and the ATA devices. The Grandstream phones are cheaply-made, I know because I have one and I'm not happy with it. I was NOT talking about phones--I'm talking about the the FXO/FXS ATA devices which are rather well though-of. Please don't confuse the two.
There is a cheaper/better FXO/FXS from Grandstream, the Handytone 488. This is a new item and can be bought for under $90. It is extremely small (a little smaller than the SPA-3000) and handles all the popular codecs. Its configuration is a little easier to understand than the huge Sipura menus. It works right away without SIP registration (Sipura needs a setting in order to work without SIP registration) which allows you to test it by placing calls to IP numbers directly.
Sipura units seem to have much more provisioning support but Grandstream supports the same provisioning protocols. This can help with large deployments where you want to automatically assign extension numbers from a central server.
Again, this a new product that just went into production and might save you a few bucks over the Sipura in quantity. See http://voipsupply.com/ and http://www.grandstream.com/ for some more detail.
I was on a job interview a couple of years ago in which the job was to develop software that currently ran on Solaris and part of the job would be to port that software to Linux. One of the questions asked, rather off-handedly, was what I thought of the then-emerging SCO litigation. I have used SCO products as well as Linux for as long as they've been around, and also have much detailed exposure to AIX and Solaris. I mentioned that I believed if SCO owned the technology of AT&T System V Unix such technology was their property and some of it is subject to patent protection as well as intellectual property protection. IBM appeared at the time to have released this technology directly into the public domain without regard to prior ownership and much of that code ended up in major Linux distributions' kernel and toolchains. I described how I read that the biggest reason that the BSD4.4-lite2 and subsequent NetBSD/FreeBSD distributions came about was because of intellectual property that had to be removed from BSD Unix (at the same time the BSD Unix project was ending). It appeared that the same thing was happening to Linux, except that today we have SCO suing IBM (instead of AT&T suing UCB).
I will never know how much that contributed to their opinion of me.
I really believe this is the fault of the email senders. The spamassassin on my email host filters all Amber Alerts, too. The person who sent the mail should have already made arrangements to get the email through to the proper people.
The article doesn't mention it but what are the chances that the email sender is using a well-known SPAM tool, or a well-known SPAM tactic?
This is a great idea if all you needed to do was cool the circuit board. The fans don't effectively cool the platters, though, and sometimes that thermistor that tells you the temperature is mounted on the same side as the circuit board, getting cooled by that fan, and showing you lower temperatures, but the platters are still running hot.
T-Mobile is the more honest of the carriers when it comes to the reality of cell coverage in their 1900 MHz network. Verizon and Cingular/AT&T also use 1900 as the preferred band. It simply does not penetrate buildings as well as 800 MHz. I recently ran around testing pay-as-you-go phones to test the signal in my office which is in the center of a building. I settled on an 800 MHz TDMA phone which gives me superior coverage, pretty much solid 3 bars at all times. The T-Mobile 1900 MHz could only hold about 1 bar and Verizon, while indicating 1 bar, could not carry a conversation. Even though my Verizon phone has support for 850 MHz in CDMA as well as analog I cannot instruct my phone to use those bands. If I could have selected 850 MHz the phone might have worked better. As it is the phone that works the best is the most obsolete one-- a TDMA with analog option.
The buzz on the wireless boards (howardforums, phonescoop) is that in 4Q05 T-Mobile will be launching a new service that uses WiFi VoIP at home and GSM wireless when you're not.
Before Verizion quipped that their wireless phones don't work at home it seemed that T-Mobile was only wireless carrier that freely admits that 1900 MHz does not work well in buildings. To address this problem they are going to sell a new phone and a VoIP access point in a bundle. The phone switches to WiFi when it is in range of your base station and switches back to GSM when out of range.
It will require high-speed internet access. This is an extremely clever idea. I was not able to find out what happens when you "roam" onto other people's WiFi networks or if you could hook up your POTS phones to this WiFi VoIP gateway.
For VARs there was a discount grade of A, B, C, and D for Sun hardware. The "D" grade was reserved for education and was supposedly was equal to cost but the margins on Sun gear was always so high, nearly as high as Apple's. We sold most of our gear under grade A for one-shots and B for larger orders and regular customers. We were never big enough for grade C.
The percentages for each grade depended on how large you were, and whether you used Merisel or Access Graphics for your distributor. I'm unsure if it's still true in today's world. This was 1994.
Solaris was just being released at the time and was sold for real cash money, too, and you could not get today's "free" upgrades. I've been a regular buyer of Solaris media kits for x86 since it came out because I believed in the product even though that $79 didn't give you a commercial license (I was a developer). Today I'm puzzled and concerned that Sun is giving Solaris away for everyone. No wonder they laid so many people off in the OS group.
That integrated memory controller is proving to be more of a nuisance. The memory, even though it runs quad-pumped close to the speed of the processor, could have used a replaceable northbridge to access the memory at a slightly higher speed. Maybe I'm being naive about that but isn't this what killed PowerPC because it didn't have DDR support for years after x86 PCs did?
The e-book readers that you can actually buy are always too large and heavy. Just punt and get the very cheapest Pocket PC you can find running Windows Mobile 2003 and has a QVGA screen. The web browser and MS Reader will use the full VGA 480x640 resolution with font smoothing turned on and you can rotate it into landscape mode. Curiously enough you will need to download a hack to keep the font smoothing turned on in landscape mode.
If you want to use Tome Reader or Adobe Acrobat Reader you can download the SVGA hack that forces the entire system into VGA mode (normally it's in QVGA which is pixel-quadrupled mode). I suspect at least Adobe will have a VGA-compatible reader soon. I know that AvantGo will not.
Total cost will be way cheaper than any dedicated e-book reader and you have the choice of Tome Reader, MS Reader, Adobe Acrobat Reader, HTML browser, eDoc, MS Word, and any other format you can think of.
You might also consider a PalmOS PDA, but in order to get on that is fast enough and has high enough resolution you will be way beyond the cost of a perfectly suited Pocket PC.
