Journal Journal: HP MediaSmart Windows Home Server update notes 1

I'm not sure why, but we bought another HP MediaSmart Windows Home Server with the intention of gifting the old one to someone else. This version is really different. Not only is the server two gigabytes of memory and uses a 64-bit CeLeron processor, it also has a large number of features that were not present in the refurbished Sempron 512-megabyte HP MediaSmart server. I'm not really sure why but this newer model has Amazon S3 backup service and a huge number of new features that aren't present on the Sempron-based version. We updated the server software on both models but only the Intel CeLeron model has the new features.

If you're going to try out Windows Home Server to automatically and effortlessly backup your Windows machines, get a non-refurbished Intel-based HP MediaSmart server. All of these new features are in the HP MediaSmart software and not WHS itself. I'm not sure why HP did this but it's eye-opening.

I'm going to try to install the Amazon S3 and other software add-ins to our older, refurbished model by doing a "factory restore" from the Server Recovery Disc that came with the non-refurbished model and see if these awesome features get installed on the older server.

Very interesting difference. It might be that the newer one has two gigabytes of memory and the other one only has 512 megabytes. It's possible the features are dependent on the memory specifications of the server, but I doubt it.

The Mozilla Flashblock plugin is getting fooled by advertisements on some sites like urbandictionary.com which use a countermeasure (seems to be iframe abuse). Installation of version 1.5.11a2 from the special link http://flashblock.mozdev.org/installation1.html solves the problem for now.

Journal Journal: Why Cox Cable's video service is stupid

Here's the stupid thing about Cox Cable Television in the Northern VA area.

Technicians are going crazy yanking old cable off the telephone poles to install multi-wavelength fiber and switched-video-compatible boxes because they ran out of bandwidth to compete with all the HD channels that the other services, like FiOS and satellite, offer.

The stupid thing is that FiOS has the same 1 gigahertz video capacity that cable does (not including Video-on-Demand which is served by Internet on FiOS and through hidden video channels by Cox). Likewise, FiOS has twice the SD channels and HD channels without the need for switched-video to solve a perceived bandwidth problem.

This doesn't make sense. I did some digging. For now I still use cable internet so I scanned the Cox Cable signal on my HDTV and found out that nearly all of Cox Cable's SD channels are still analog. This means that most of Cox Cable's 1 gigahertz of bandwidth is consumed by analog channels at 6 MHz per channel, even though you can fit more than 10 digital channels in one analog channel if they were to use digital instead.

Why is Cox Cable spending so much money installing switched-video if all this bandwidth is available?
Why isn't Cox Cable using digital for their SD channels?

Apparently the bandwidth required for Video-on-Demand is the business reason for the switched-video upgrade, but switched-video is not just for VoD. It is also used on non-VoD channels because of a system-wide bandwidth shortage on Cox Cable. This means if nobody in a neighborhood watches Food Network HD, it gets turned off until someone tunes it in again.

The cause of the problem is that Cox Cable is still using 6-MHz-per-channel analog for most SD channels.

Journal Journal: Godwin's Law for Software Engineering 2

In professional Software Engineering circles we debate topics with real-world applications.
Sometimes, the debate must be aborted when a participant quotes one of the following so-called pundits. Most of them are academics or failed dot-com company founders.
The key point here is that "professional Software Engineers," referring to people who make a living actually accomplishing real work on real systems.

Here is the list of Godwin's Law violations.
Quoting them makes you forfeit your side of the debate:

Journal Journal: Google Apps, Writely, Tonic Systems

[Written as a response to a LinkedIn.com question concerning the use Google and Adobe's online applications instead of Microsoft Office]

I dare suggest that the Writely and Tonic Systems applications that became Google Apps are very simple and rather slow when compared to OpenOffice.org or Microsoft Office.

The global accessibility is appealing if you are not able to use an internet file sharing service or a remote login program like LogMeIn.com but you lose a large number of important features using Google Apps and you sacrifice your personal, and more importantly, your business', privacy and security.

Finally, if you are concerned about privacy, you should know that Google's agreement reserves the right to anonymously search, index, and catalog your "private" files. This is the same thing that Google does with Gmail. While they currently only use this for targetted advertisements you should be aware that they are scanning, indexing, and cataloging all of your data.

Google exists to scan, index, and catalog the entire body of data in the world. If you like that idea, then you are contributing to it by using Google Apps.
If you want to preserve your personal and business security you should not use it.

Journal Journal: Consumer Products for Computing 2008

More consumer products for computing and an update.

1) Logitech Marble mouse for daily use. Kensington Expert Mouse for continuous use.

2) SIIG MiniTouch Plus PS/2 keyboard with 5-year warranty appears to be out of production but there is plenty of stock on hand at all the major retailers that report stock levels.
This same keyboard is also sold as the generic BTC-5100C keyboard in either ivory or charcoal gray.
The recent SIIG production models actually have "BTC-5100C" in the model number, but only the SIIG model has a 5-year warranty. The BTC version is about $15 cheaper but is only warranted through the vendor.
Both brands of this fabulous sub-$40 keyboard easily trump all the $60+ Happy Hacking keyboards since they have the backspace and back-tick keys in the expected places for PC users, and the full-width caps lock key is suitable for use as your control key.
The most recent models have a clean, silent feel. Earlier SIIG models have squeaky, noisy feel, which can be remedied by a warranty replacement which supplies you with the most current SIIG-branded BTC model.

3) The Hawking H-U2PS2 PS/2 to USB converter is the only PS/2 converter that properly accounts for keybounce elimination, multiple key chording, and can keep up with touch-typists. It also has special support for all the key sequences required by Sun machines.

4) Dell's cheaper flat-panel monitors. Even though these are TN panels they are clear, bright, and don't have stuck pixels.

Journal Journal: Freetype configuration in Linux for 2008

The Linux font rendering situation has changed yet again.
Here is the configuration story for 2008.
This works for Fedora, Red Hat Enterprise Linux, Ubuntu, Debian, and CentOS releases.
Ubuntu has enabled these features except for the light LCD filter, so read on even if you're using Ubuntu.

Download the HEAD version in cvs at www.freetype.org or a recent snapshot.
There are some new algorithms that most of the font guides out there do not address.

By the end of 2007, Freetype includes two entirely new algorithms. The first algorithm is a color sub-pixel hinting algorithm. The second is the LCD filter. This means that there are now three algorithms that are configurable in Freetype that are probably not configured properly on your system.

All of these are set in the source code at build time in the file:
$TOP/freetype2/include/freetype/config/ftoption.h

1) Color-shaded sub-pixel rendering is normally disabled but you'll want to enable it even if you don't have an LCD monitor. This is the feature that is sometimes known as "ClearType" on Microsoft Windows and "Font smoothing - Best for LCDs" on MacOS.
Find the line that contains the string FT_CONFIG_OPTION_SUBPIXEL_RENDERING and change it to:
#define FT_CONFIG_OPTION_SUBPIXEL_RENDERING

2) The color-shaded sub-pixel rendering creates severe color "fringing" artifacts so there is another algorithm that cleans this up called the "LCD Filter." There are several settings to this filter but you'll want to use setting number two, the "light LCD filter." This setting is completely absent so you need to add it.
Right before the line that says "FT_END_HEADER" you add this line:
#define FT_FORCE_LIGHT_LCD_FILTER

3) The Apple-style of handling of composite offsets can usually make text appear in the right places, but only on OpenType fonts. It only happens on non-OpenType fonts if you force Freetype to do so. This setting makes it happen:
#define TT_CONFIG_OPTION_COMPONENT_OFFSET_SCALED

4) The Freebyte bytecode interpreter can be enabled but I recommend you do not. Most of us know about this one already. You won't want it because latest Freetype release renders the fonts so cleanly and naturally using the color-shared sub-pixel algorithm. In addition, if you do use the bytecode interpreter instead of the auto-hinter, the Windows Vista fonts like Constantia turn into bold-weight fonts above approximately 10 point. Conversely, the Freetype auto-hinter always looks natural and renders normal light-weight fonts.
Still, some people, like those who don't use sub-pixel rendering, need this feature so here is the setting:
#define TT_CONFIG_OPTION_BYTECODE_INTERPRETER

Okay, now build it:

sh autogen.sh; ./configure --prefix=/usr
make
sudo make install

If you have built freetype using the bytecode interpreter setting you need to edit your /etc/fonts/conf.d or your ~/fonts.conf files and be prepared to tune things (or just turn the bytecode interpreter off). Otherwise everything will look great using the autohinter.
Then restart X Windows or reboot.

Now that the color-shaded sub-pixel rendering and light LCD filter are available the fonts are absolutely amazing. You really don't want the bytecode interpreter unless you have sub-pixel rendering turned off.

Enjoy.

Journal Journal: VMware Tuning for server use

VMware can be tuned for remote access and you can return resources that you will not use to the system so it runs more snappily.

Here's what I did to the free VMware Server. It takes most of the same options that the paid VMware Workstation and GSX do.

1) Use the vmxnet network driver instead of vlance/pcnet32/e1000.

2) Turn off the virtual network driver's ROM boot code. I'm not sure why it's there.

3) Restrict video RAM to the smallest possible value to accommodate the text console only.

4) Disable 3D acceleration.

5) Turn off devices not in use (even the ones you cannot turn off from the VMware Console GUI, like the SCSI device on an IDE host). Note the values 'device.present = "FALSE"'.

6) Adjust performance, scheduling, and memory handling.

7) Make the backing store use the host computer's RAM instead of a file on disk (this is in the global config.ini, not the vmx file).

There are two files pasted below.
First is is the vmx file that you might use for a CENTOS/RHEL system.
Second is the global VMware settings file which goes into "c:/Documents and Settings/All Users/Application Data/VMware/VMware Server/config.ini".

Make sure you shut down all VMware services in the Services control panel before you change these because the VMware Console might over-write your changes.

VMware Console will honor your changes for the most part.

Journal Journal: VMware Registration Service fails to start for some reason

I have the problem with VMware guest hosts not working upon computer startup because of "VMware Registration Service" failing to start. It appears that the service is starting too soon in the computer's startup sequence. I have verified it to happen on Windows XP Home, Windows XP Professional, Windows 2000 Workstation, and Windows 2000 Server.

I am unsure which service I should make the "VMware Registration Service" depend on, so I didn't bother changing any of those settings in the Services MMC window.
Instead I wrote a tiny script that I put in my startup folder which solves the problem as long as the Administrator logs into the computer (which is not ideal for Windows 2000 Server, but for my needs is okay). If you want the script run unattended without logging in you might try to put it into HKLM\Software\Microsoft\Windows\Current Version\Run but there it will probably also start too soon to work.

The script is very simple. Call it "vmwarestart.cmd" and place it somewhere in your PATH:
net start vmserverdWin32

The nice feature of the "net start" command is that if this service is already running it doesn't try run another copy.

This completely solves this annoying VMware Server 1.x problem on all my Windows XP Home, Windows XP Pro, Windows 2000 Workstation and Windows 2000 Server installations.

I'm disappointed that VMware/EMC doesn't believe that the problem exists.

Journal Journal: Satellite dishes proliferate in southern/eastern NY boroughs

I spent a week in Queens and parts of Brooklyn recently and noted the sudden proliferation of satellite dishes all over the place. I surmised that the backup transmitters put up after the September 11 attacks were not adequately serving these boroughs and the satellite broadcasting companies aggressively marketed to these areas. Even high-rise buildings have significant numbers of DiSH Network and somewhat fewer numbers of DirecTV dishes both on rooftops and hanging outside individual windows.

It turns out that the temporary transmitters, still in place five years later, are far from adequate for these lower boroughs.

The Empire State Building transmitter facilities are much less than adequate. The huge, ancient antenna that rings the observation platform was brought back to life but kept at a very low power, around 800 watts, to protect the tourists on the platform from radiation. The main antenna on the famous mast had always been intended for FM broadcasters (there were 18 using it before 9/11, and 22 using it afterwards). There are also several directional backup antennae which leave significant nulls, too, but they have to do what they can to get a signal out there. Throughout Manhattan there are backup antennas on much shorter buildings (Conde Nast, Viacom) but they are affected by significant multipath and interference from nearby buildings and other transmitters, to say nothing of their low power.

Outside the city the much higher-powered backup facilities on the historic Armstrong tower in northern Alpine, NJ cannot penetrate the buildings of Manhattan to reach the lower boroughs.

This leaves WCBS-2 the only good signal in Brooklyn/Queens with a high-powered omnidirectional antenna on Empire State Building.

The city's broadcasters formed the Metropolitan Television Alliance to seek a new communications tower to be built within 3.2 miles of the World Trade Center site. It would need to be 1,800 to 2,000 feet tall. The Freedom Tower is being configured to handle broadcasting needs but the broadcasters do not want to wait another 5 or more years when a communications tower can be built within months.

Naturally the site for the tower is being debated hotly among politicians. New Jersey has several optimal sites but that's politically undesirable. The mayor doesn't want a tower on Governor's Island, another optimal site. The airports need to be accomodated, too. The Meadowland sites in New Jersey, traditionally used by AM broadcasters, are optimal, too, but have the dual stigma of New Jersey location and any high tower's conflict with the flight plans of Newark "Liberty" Airport.

As side note is that DTV is practically nonexistent due to the destruction of most of the major broadcasters' DTV equipment at the World Trade Center.

Since it costs more to purchase a good television antenna than a complete satellite system this means more business to the satellite broadcasters. Indeed I saw expensive television antennae on 50-foot masts on homes and buildings in Queens that nonetheless also had satellite dishes installed.

New York's television viewers, 30% of whom had no cable or satellite before September 11, 2001, are still waiting for things to return to normal five years later. This is sweet news to the satellite broadcasters in the aftermath of the terrorist attacks.

Journal Journal: Java GUI Development

I am writing a Java-based application with a Graphical User Interface (GUI). Everyone I had asked said there were no good, and certainly no worthwhile "free" GUI builders for Java.

NetBeans 5.0 has a GUI builder built-in.

I encourage anyone starting Java GUI development take a long look at NetBeans 5.0 and later. So far it has almost everything I think a GUI builder should. In addition the automatic code generation looks and feels like you wrote it yourself.

I'm still investigating Elipse--it does not appear to have a built-in GUI builder and I have to sift through a large list of plugins to get one working.

NetBeans is the one for me.

Journal Journal: Wireless Cable Finally Dead

The FCC opened for bidding the new "Advanced Wireless Service," or AWS-1. This band is allocated in several sub-blocks in the 1710-1755 and 2110-2155 MHz ranges. Fans of Sonny Block and other Wireless Cable investment scam artists might remember that this used to be the band used by Wireless Cable.

The band sometimes known as Wireless Cable was officially known under many different names: Broadband Radio Service (BRS), Fixed Microwave Service, Educational Broadband Service, Instructional Television Fixed Service, and Multipoint Multichannel Distribution Service (MMDS). Wireless Cable, a victim of various boiler-room investment scams, was to be a primary user of this band. Most of these services never launched a commercial product. The band to this day is largely unused.

BRS had been intended to be used for digital multiplexing services using small roof-mounted parabolic antenna arrays in the 2.1 GHz band. At that time the use of digital multiplexing was a somewhat novel concept and, if launched, would have resulted in Wireless Cable services with over 100 channels. It never happened and Sonny Block, heard on WWOR-AM and other radio stations, fled the country was was extradited and eventually landed in a U.S. jail.

Now T-Mobile is a major bidder for the new AWS-1 band which will be used for digital broadband mobile services.

Journal Journal: Canon Rebel XT body memory card issues

My wife bought a digital Canon XT Rebel camera recently and it did not like our equally new 2-gigabyte CompactFlash card. It keeps saying "format card" or something similar. I took the card to my PC's card reader and re-formatted it using FAT32 and it now completely works. I noticed this card has a switch to let you use two partitions of 1GB each in FAT16 but instead I re-formatted in FAT32 and it works in the camera just fine, thank you.

I think Sandisk must be getting lots of returns from Canon Rebel XT users.
