Vlad Hrybok's Tech Notes

Here's what I didn't get from U-Verse despite sales woman's promise:

• Static IP address: they don't do it. Period. The best they could do is to setup 28 day (instead of 24 hour) DHCP lease for my IP address.
  
  
• Free receivers/STBs with U-Verse TV U100 package: Was charged for each additional receiver and had to negotiate with AT&T. Got credit to the current bill and six month promotional discount to bring the price close to the initially stated. What happens after 6 months - don't want to think about it right now.
  
  
• Price lock-in: I was promised that price won't go up. Not the case - AT&T rep on the phone said there is no such commitment.

The bottom line: videotape or at least record what your sales person commits to, including your services and amount you are going to pay in recurring charges, plus make her state discounts and rebates you will receive.

I asked U-Verse installation tech to use CAT5 Ethernet wiring instead of coax, and he didn't mind. He wired all rooms where I have TVs or computers with Ethernet CAT5e cable, and hooked them up using RG ports and a Netgear Gigabit switch AT&T provided. Needless to say, you can add any number of computers later if you deploy your own switches, preferably Gigabit ones to ensure there is plenty of bandwidth to carry multiple TV streams along with regular network traffic. Wiring up your house for Ethernet is a good freebie from AT&T. Be sure to tell your U-Verse sales person how many rooms you want to wire. Also make it clear to the installer tech which rooms with TVs and computers you want to wire BEFORE he starts. If you change your mind or remember you left out a room with a TV or PC, AT&T will charge you for added wiring.

UltiDev HttpVPN is in an incredible position to be the winner in this market.

(Updated 7/4/2008). Unlike Windows XP or Windows Server 2003, changing a motherboard on a machine running Windows Vista (in my case Vista Ultimate x64 with Service Pack 1) is not mentioned in the Microsoft Knowledge Base article addressing the MoBo upgrade. I tried a couple of approaches described below, but the bottom line is that the same process worked for Windows Vista, with one important difference: Vista upgrade process takes many hours. Waiting for that first reboot - the point where you replace the board - took close to two hours! And then it took a few more hours to complete the upgrade process. In the end the machine booted up and most of applications seem to be working fine.

Applications that didn't fare well are:

• Daemon Tools
  Symptoms: When system is booting, a cryptic error message is displayed, complaining about Windows version or something. Worse, an attempt to uninstall Daemon Tools failed. However, deleting the folder with Daemon Tools made the problem go away.
  Solution: Uninstall Daemon Tools before upgrading the system, and reinstall it after upgrade is complete.
  
  
• Windows Mobile Device Center
  Symptoms: Connecting a smartphone caused Windows Mobile Device Center to crash.
  Solution: Repair Vista installation again. After I ran an upgrade installation of Vista again (overnight, because it takes untold hours to complete), this problem went away. Please note that unlike XP, Vista does not have a separate Repair Installation option. You must run Upgrade installation (for that start installation from Windows) in order to repair existing Vista installation.
  
  
• Microsoft Visual Studio 2008 Dataset Editor
  Symptoms: Opening and XSD schema or a Dataset in Design mode in VS 2008 resulted in opening the file either as a text, or as XML.
  Solution: Please check this post.
  

Now a little more about how the first upgrade attempt went down.

Having to watch the upgrade screen for hours in order to intercept the first rebooting is no fun, and ironically can be mitigated by the bug on the "Vista x64 with SP1" DVD, which makes a rebooting process always stop indefinitely waiting for user input. This bug is a mixed blessing, because you can go about your normal life while waiting for the first reboot while the existentially-named "Gathering Files" step of the Vista upgrade sequence is running, but after you have replaced the main board you want the upgrade process do its reboots without your involvement, and that's where the bug turns from being a help to being a hassle. Anyway, you would be wise to allocate half-day for the motherboard upgrade on the Vista system, and by all means back up your system before the upgrade.

Failed Mobo upgrade approaches included uninstalling board-specific drivers before turning the PC off and replacing the motherboard. It didn't work at all - machine went into reboot loop. Attempts to boot in the Safe Mode stopped at BTHidMgr.sys, which I later found could be related to having Nero's InCD installed. I don't have InCD, but I do have Daemon Tools, which incidentally is the only application that stopped working after the upgrade. I never tried to remove Daemon Tools before trying the Vista upgrade path, so the next time I would recommend trying the quick "uninstall drivers, uninstall Daemon Tools/InCD, Reboot" approach first. Only if that does not work, get the huge bag of popcorn and do Vista upgrade.

Upgrading or replacing a motherboard on a machine running Windows Server 2003 (in my case it was Windows 2003 R2 Standard Edition with Service Pack 2 x64) is relatively straightforward, and more or less works as described in the MS Knowledge Base article: you start upgrade process by running Windows setup while old motherboard is in-place, and once upgrade process reboots the machine, you intercept it by turning the computer off and replacing the MoBo, and then allow upgrade process to continue. It worked alright, and wasn't too long a process.

What the KB article didn't mention is that after the upgrade a few things may be broken or missing. In my case there were two big things broken:

• IE was corrupted in a way that prevented downloading files by clicking a link. Page browsing still worked and "Save target as..." worked, but clicking a link that redirects to a file download resulted in the strange error message: "The requested look-up key was not found in any active activation". My way to fix it was to upgrade IE6 to IE7, but since IE7 download links were those redirect links that didn't work, I had to install FireFox, which had a link accessible via "Save target as", and then I used FireFox to download and install IE7.
  
  
• .NET Framework 2.0 has disappeared, wracking havoc making pretty much all applications (SQL Server Management console, ASP.NET apps in IIS) not working. Fixing it was not too bad though - I downloaded and installed .NET Framework 2.0 x64, then made a couple of runs of Windows Update to ensure the server won't try to reboot soon after being brought online, rebooted the machine just in case, and that was it.

Overall entire process, although not completely seamless or worry-free, took only about an hour, not counting time required to physically replace the board.

Recently I started getting "IO Error" while backing up my computer that runs under Vista. To back up I used Vista's "Backup & Restore Center". Somewhere closer to the end of the back up process it would just throw this IO error seemingly with no good reason. About five last attempts to backup ended with this error. I used to get that error a long time ago, and then the error would occur only sometimes, and on different systems. That time I was able to eventually track the problem to faulty USB cable, but this time was different - error was occurring on just one machine, and once it started happening - it never went away.

I noticed, however, that on the machine where the error was occurring, system drive where Vista and most of everything else is installed, is running out of free space. I got "only" 1.7 GB left. I didn't think that should be a problem, since 1.7 GB is still quite a bit. Nonetheless, I decided to reshuffle partitions to increase the size of my primary partition. Once I've done that, I made one more attempt to backup my machine, and this time it's worked.

The bottom line: be sure that drive you back up (or maybe just your system drive) has enough free space.

I will update this post if the error resurfaces or if I find out that amount of free disk space has nothing to do with the error.

Today we had an electricity outage cause by thunderstorm. While UPSes were still alive on both network segments connected via ZyXel PL-100 power line adapter, I tried connecting them into UPS and see what happens. Unfortunately it didn't work. When both adapters were connected to UPSes, Link led on both adapters was off. After power came back up, it changed nothing - no connection through UPSes. When I connected one adapter directly to the wall, and one through an APC-made UPS, Link leds came on, but computers still didn't see each other. As soon as I connected both adapters to the wall, connection was re-established.

The bottom-line: If you need network connection in your house to stay on during power interruptions, use wireless networking instead of power-line adapters.

CodePlex.com - a relatively new open-source collaboration platform from Microsoft that came to replace old and cranky GotDotNet - has impressed me quite a lot. Of course it closely resembles SourceForge.net, with the main difference of CodePlex being underpinned by Team Foundation Server (TFS) for source control and issue tracking functionality.

People often don't realize that TFS client that integrates into Visual Studio 2005 can be downloaded and is completely free.

I currently host a couple of projects on Codeplex:

• MS AJAX 1.0 Setup Project Prerequisite for Visual Studio 2005.
  It makes MS AJAX redistributable by including it into the Setup.exe bootstrapper prerequisite manifest. The prerequisite integrates nicely with Visual Studio 2005.
  
  
• Simple ASP.NET 2.0/C# MP3 Player.
  This application demonstrates a possibility of building a web application for home users. It includes redistributable UltiDev Cassini Web Server for ASP.NET 2.0 to not make the application dependent on the presence of IIS on users machines. The app is AJAXed to minimize music interruptions and uses Flash player to playback MP3 to avoid dependency on any particular media player. 

After releasing build 1.7 of my open-source redistributable ASP.NET-based MP3 player application, I used it for a while and I am pretty happy with its stability and functionality. The design goal for the project was to demo a concept of an easily-redistributable web application for SOHO market. With unquestionable popularity of web-based applications in the business world, removing complexity of the web hosting infrastructure to make home web applications possible as a category is poised to be the next big thing.

Until recently I've been running MCE 2005 on Windows XP with Linksys Media Center Extender (MCX) connected to the XP box over 802.11a wireless network. That was a nice and stable setup, but with the technology moving forward it was time for an upgrade. I have successfully upgraded XP to Vista, and since Vista did not support "old" Media Center Extenders like the one I have, I had to get XBOX 360 - the only game in town when it comes to extenders supporting Windows Vista.

Cursory Google search revealed that even most basic and least expensive XBOX 360 version, the Core System, can run the extender application just fine by loading the MCX software from the Vista box over the network. Far more serious issue for me was how loud XBOX 360 is. The thing is that Media Center Extender box is located in the bedroom, and any fan noise from XBOX 360 would be very annoying. Linksys Media Center Extender was not just quiet - it was completely silent. It has no fans or motors at all. The price for the silence was that its CPU was underpowered and therefore it was mostly nothing but a dumb Remote Desktop terminal displaying the UI rendered on the XP box, with the exception of rendering the streaming media on the MCX box itself. XBOX 360 has a very powerful multi-core processor and therefore is easily fit to render all the fancy MCX UI right there, which makes UI of MCX running on XBOX 360 much more responsive compared the Linksys. The price of the performance, besides $300, is the fan and its noise. How much noise exactly? The whole reason I write this post is because after searching the "Internets" I was unable to tell whether the level of noise is acceptable or not. Some people complained that it's horrible, and some said it's OK. Well, here's the verdict: yes, the noise is bad and I can't believe Microsoft didn't find a solution to the noise problem, BUT the remedy is you can turn XBOX 360 completely off when you are not watching it! Noise level when you use the XBOX is not uncomfortable at all. The drawback is that it takes XBOX about 50 seconds to boot, load MCX application from the server, and launch the MCX UI when you turn the XBOX on (which BTW can all be done at once by pressing Mediacenter Green Button on the mediacenter remote). I don't mind paying the 50 second price for the complete silence of the turned off XBOX, while being able to enjoy fast and responsive UI of the XBOX setup.

Another quick note on the subject - the networking of the new extender. Linksys extender had both wireless and wired networking capabilities. I ran it over 802.11a (Wireless-A) network that is fast enough for streaming recoded TV and at the same time is not susceptible to interference from all the 2.4GHz devices like cordless phones and 802.11g (Wireless-G) networks of your neighbors. XBOX 360, however, has only wired networking capabilities, and since our house is not wired for Ethernet, I had to use ZyXel power line Ethernet adapter. I really like ZyXel power line adapters - they are great alternative to wiring your house or using wireless networks. When I was setting up extender piece on the Vista machine, MCE tested the network bandwidth and found the throughput not sufficient for streaming TV. I though it's strange because ZyXel PLA-100 adapter is supposed to be 85 marketing Mbit (about 45 real Mbit) - quite faster than 22 Mbit of the Wireless-A network that was working just fine. Sure enough, TV and video streaming ran absolutely smoothly over ZyXel PLA-100. However, whenever we get an HDTV set connected to the extender, we'll need to upgrade ZyXel adapters to speedier 200 marketing Mbit (hopefully about 100 real Mbit) PLA-400.

[June 12 UPDATE: The same day when I wrote this post I noticed that network performance of the setup has degraded to the point of recorded TV being unwatchable: picture would freeze or won't start playing back at all with the black screen, with "Network Issues" pop-up ever-present on the screen. I thought the problem is ZyXel PL-100. I replaced it with Viewsonic 802.11g access point connected to XBOX 360, and just like with PL-100 it worked flawlessly the first time I turned on the XBOX, but went down exactly the same way as the the power line adapter based network. Funny thing is that if I hit Fast Forward button on the MCE remote, FF works and produces absolutely smooth video! So at normal rate it crawls to the stop, but with fast forwarding there are no "Network Issues"? I was able to playback the same recorded shows over the same network connections using notebook and WIndows Media Player with no problems. I think Microsoft has a whole lot of explaining to do about its XBOX 360 "networking issues".

Although usually I prefer to make a clean installation of a new OS to lose all the junk accumulated since last OS upgrade, this time I decided to upgrade our family Media Center box instead, because unlike my desktop the MCE box has just a few basic server apps, like IIS, email server, ORB, WebGuide, and of course MCE 2005.

Overall, upgrade was a success, but most of the drivers and applications had to be either upgraded or reinstalled. There were quite a few things to take care of:

• Running Vista Upgrade Advisor was a good idea. It tells upfront which drivers, services and application will not, or may not work. The most important thing it told me was that I don't have enough space on drive C:, so since it was still an XP I used Norton Partition Magic to increased the C: partition size by 25 GB. I also downloaded some Vista drivers before starting the upgrade just in case my network card would not work after the upgrade.
  
  
• Although ATI Catalyst software was not among those Vista Upgrade Advisor suggested to remove, the screen resolution settings were not preserved by the upgrade process. Moreover, standard MS ATI driver didn't support resolutions required by some HDTV sets. I had to visit ATI web site and download the latest driver and the Catalyst software. Once I've done that I was able to adjust the resolution back to what it used to be.
  
  
• MCE settings partially survived. Scheduled series settings carried over fine, but Signal settings and Guide had to be specified again by going through the setup wizard. I had my recorded TV shows location in XP MCE changed from the default. While new MCE in Vista has found them, I still had to specified the location for new recordings. Thankfully, it was easy - the UI allowing to change the location of newly recorded shows is built into Vista's MCE app. Pictures and Music location settings have carried over with no problem.
  
  
• The hardest part was to revive ASP.NET applications and sites after IIS was upgraded from IIS5 on XP to IIS 7.0 on Vista. The hardest problem was that caused by the remnants of some old version of .NET Framework 2.0. That caused application pools hosting .NET 2.0 to crash hard on the very first request while spitting out strange errors, like "The worker process failed to pre-load .Net Runtime version v2.0." to the application log. It took me two days of Internet searching to find the solution.
  
  ASP.NET 1.1 applications were also all not working. I had to run aspnet_regiis.exe from the 1.1 Framework to bring them back to life.
  
  In many cases I had to manually ACL folders containing ASP.NET applications with access rights for "NETWORK SERVICE" user account. I also had to change anonymous authentication account from IUSR_whatever to appPool identity.
  
  The bottom line is migration of ASP.NET web apps was not trivial.
  
  
• Both Orb and WebGuide stopped working after the upgrade. I upgraded ORB with no problem and uninstalled the WebGuide so I could install Vista-specific version of the WG. It all went fine - that's after I was done fixing all the IIS7 glitches.
  
  
• dasBlog 1.9 - the software running this blog - ended up being incompatible with Vista. I had to move this blog to another server running good ole' Windows 2003/IIS 6.0. After moving the app to another server, which was free of surprises, the final challenge was to redirect links going to old blog location pointing to IIS7/Vista to the new one. Unlike IIS6, IIS7 does not have a UI where you could choose "A redirection to a URL" as a destination for your virtual directory. Redirection in IIS7 can be done but it requires running a command-line utility. Fortunately that worked.
  
  
• Unlike IIS, UltiDev Cassini Web Server underpinning WebGuide4 went through upgrade precess as smooth as it can be.

Summary

UPDATE: This sample is an open-source project now.

This article describes how to build a redistributable ASP.NET application that allows users browse remote server's file system and pick folders with MP3 files to be played by embedded Macromedia Flash-based MP3 player.

Article Sources

Download article's C# source in a form of Visual Studio 2005 Solution comprising ASP.NET application and a Setup Project. Unzip the archive to "C:\".

End Result

  

After building the project you will have an MSI-based setup package that can be installed on virtually any Windows-based PC. Installed application will be accessible from inside the LAN as an intranet application without having to install IIS.

Prerequisites

- Visual Studio 2005.
- UltiDev Cassini Web Server for ASP.NET 2.0. UltiDev Cassini is packaged together with the application into the Setup.exe so that the final application would not depend on IIS being present on target system.

Let's Begin (Getting Ducks in a Row)

A few weeks ago I stumbled upon a great piece of free software:Flash-based XSPF-compatible MP3 player. When embedded on a page, it can take playlist over HTTP and play it. Second nice thing was that XSPF play list format has XSD schema available. .NET Framework xsd.exe utility allows easy conversion of XSD schemas into C# or VB.NET classes incapsulating the structure of the data defined by the XSD, as well as implementing XML serialization to and from XML files conforming to the schema. So I had an XSPF-compatible MP3 player and a free code generating XSPF-compatible XML. That meant I could easily create XSPF-compatible playlists on a fly. Only if I had free ID3 tag (MP3 file metadata) access API...

Finding ID3v2 library for .NET was harder than I expected. However search was ultimately successful. The UltraID3Lib ended up being just what I needed. It's a nice library; may be just be a bit over the top object-oriented.

Final piece is UltiDev Cassini Web Server for ASP.NET 2.0. It's necessary because first, it can be packaged and shipped along with any ASP.NET application eliminating requirement for IIS. Second, unlike IIS UltiDev Cassini service works under "Local System" account, which enables access to any local file and folder on the server. One thing to note, while this is quite convenient to have a web server running under powerful account, it may pose a risk if the application is exposed on the web. It's best to work with the application inside protected local area network.

After you have downloaded the solution, unzip it on C:\. It will create "C:\UltiDevMusicPlayerSample" folder. If you want to put it in some other folder - you can do that too - simply adjust your project debugging settings later to point to the correct application folder (see below).

Application Flow

- Application has a single page (Default.aspx) containing the player control and file a system browser (Controls/PlayerControl.ascx and Controls/PlayerControl.ascx.cs).
- After user selected a folder with MP3 files, file system browser tree gets hidden and player control is re-rendered to point to the dynamically-generated playlist representing selected folder.
- Player control requests dynamic playlist and custom IHttpHandler (AppCode/PlaylistClass.cs and AppCode/xspf.cs) serves XSPF-encoded playlist containing songs in the selected folder. Playlist contains song information retrieved from songs' ID3v2 and ID3v1 MP3 tags.
- Player plays songs one by one: requesting each one from the custom IHttpHandler (Handlers/Song.ashx) serving songs from local file system. After song started playing player also requests song album artwork (cover art) from custom IHttpHandler (Handlers/CoverArt.ashx) which serves image extracted from song's ID3v2 tag.

Debugging

I had troubles getting Visual Studio 2005 internal web server to serve Flash component. I switched to UltiDev Cassini for debugging and that has solved the problem. Debugging with UltiDev Cassini is probably a good idea anyway since the application is eventually going to run under UltiDev Cassini.

To switch to UltiDev Cassini, bring up ASP.NET application's properties, select Start Options of the left, and check "Start External Program" radio-button. Enter "C:\Program Files\UltiDev\Cassini Web Server for ASP.NET 2.0\UltiDevCassinWebServer2.exe" as the program to be used for debugging, and specify "/run c:\UltiDevMusicPlayerSample\WebApp Default.aspx 4125" (no quotes) as command line arguments. If you have unzipped solution to a folder other than "C:\", then you will need to modify c:\UltiDevMusicPlayerSample\WebApp part of the command line arguments to point to the actual application location.

Setup Project

Unlike regular ASP.NET application, this application is using regular (non-web) setup project for installer implementation. The reason for that is the Visual Studio web setup project is actually IIS setup project. Since we are using UltiDev Cassini instead of IIS, regular setup project is required instead.

Setup project packs UltiDev Cassini into Setup.exe bootstrapper and ensures application is registered with UltiDev Cassini during installation process and gets unregistered during uninstallation.

Creating a setup project for ASP.NET application bundled with UltiDev Cassini is not complex, but if you need step-by-step guide, please refer to this walk-through.

IMPORTANT: When installing the application, don't just click the .MSI file. You will need to run Setup.exe to ensure UltiDev Cassini web server gets installed on target system. This is especially true on Vista, where clicking .MSI and running Setup.exe are not nearly as functionally close as it used to be on Windows XP.

Build & Enjoy!

Think what would happen if Microsoft was giving away Windows for free to everyone, and would also be giving away Visual Studio to developers, but taking %% of every sale of every program ever made for MS Windows. Think of how much more money would they would have made? Could Bill Gates have become  a first trillionaire?

First of all, no worries, I am not a nut who writes another OS. Creating a new operating system is WAY too complicated, costly and most importantly financially risky: OSes are commodity - it's impossible to change the world by creating another OS now.  Instead, I am creating a new platform. What is platform? To give a definition, platform is an operating environment for programs, and a user interface conduit for users. To give a few examples: Internet is platform: back-end web server is an operating environment for programs and browser is a conduit for the UI; every operating system is a platform: Windows, Linux, MacOS – their APIs and drivers form an operating environment and OS desktop and windows is a UI conduit; web browser is a platform too, albeit a limited one – it can run client scripts and therefore it’s an operating environment and a UI conduit at the same time. You get the idea…

Platforms differ in reach and complexity. Operating systems make a somewhat mediocre platform: they have limited reach – contained by the hardware they designed for, by how incredibly expensive it is to make an OS, and by how hard it's to learn to develop applications for a new OS. Adoption threshold for a new OS is very high. Web, on the other hand, is a very good platform: HTTP protocol is insanely simple, web development is relative simple and mastered by ever-growing legions of developers, web is not constrained by hardware, and finally web has a virtually unlimited reach. Curiously, web as a platform is built on top of other platforms - underlying disparate OSes running web server back-end software and user browsers. it’s a platform layered on top of other platforms – OSes.

The drawbacks of the Web as a platform include:

1. Deploying and operating web apps is complex and costly. It is very hard to make an application accessible on the web: all the routers, firewalls, networking, DNS servers, domain names leases, IP addresses -  everything involved in deployment of a web application is much more complex from user’s standpoint compared to regular program with a "pop-in a CD and have it installed" type of deployment;
   
   
2. Web applications are hard to market. From developers’ perspective business models for selling web app is limited to big-ticket sales to businesses who have budget and skills necessary to run web-facing infrastructure.

Now, imagine World Wide Web with above-mentioned problems removed. That is what I am doing: a new web-based platform that has user reach as wide as current Internet, but removes application deployment and marketing hurdles that are limiting web application usage right now. That’s a unique innovation right there. “But hey, there’s more!” Another unique innovation is the business model: I am not going to sell this platform to users, or development tools to developers. All will get it for free. The catch? All software that uses our platform can only be sold and bought using channels belonging and controlled by UltiDev, and like eBay we are going to take %% of every application sale.

You may have some concerns, like will developers find this new platform attractive enough to spend effort learning it and making programs for it? The answer is no, they won’t. Because they won’t need to. The beauty of it is that application developers can take their existing skills and even their already-built applications and simply package them together with our new platform components and ship it to users. Every member of millions-strong army of web developers worldwide is ready to take advantage of this new platform.

You may also wonder how complex is this new platform? Will it take billions of dollars an decades to create it? Well, it’s complex enough to take two years to develop, but the good news is that it’s virtually finished and working pre-alpha releases are deployed. 

Small detail: the platform described above is called HttpVPN™ and some additional technical information is available at http://ultidev.com/Products/httpVPN/.

Here's how it works: for the last two years we at UltiDev LLC work mainly on HttpVPN - our flagship product and the main reason why our company exists. Once upon a time we've decided that making a simple redistributable web server software would be a great value-added piece completing HttpVPN offering and allowing us to probe prospective market for HttpVPN, gather contact information of people who may by interested in HttpVPN and setup our QA, build and release processes along the way. The experiment turned out to be as successful and we hoped it would be. We've got about 15,000 (and counting) installed UltiDev Cassini Web Server runtimes worldwide and we are receiving overwhelmingly positive feedback from users. All this also means that about every six months we have our Cassini task tracker full enough to suspend HttpVPN work for a few weeks and do another release or UltiDev Cassini. This time was no exception.

Although we always hope to keep our Cassini mid-version upgrade development cycle limited to three weeks, it took us usual five weeks to fix, test, fix again, test again and release the latest version of UltiDev Cassini Web Server. This release had two main points of focus: to eliminate all known installation/registration hurdles and to make UltiDev Cassini compatible with all 64-bit Windows platforms. 64 bit OSes are gaining popularity very rapidly thanks to the fact that most of the recent (and even not so recent - think Pentium D) CPUs from AMD and Intel are x64-compatible. Windows Vista comes in 32- and 64-bit versions right from the start, while existing Windows XP Pro x64 and Windows 2003 Server 64-bit were somewhat obscure because they were released before 64-bit CPUs hit the mainstream. Nowadays it's pretty much impossible to buy a CPU that does not have x64 compatibility. Hoping to please Vista 32 and 64 bit users we made sure that our latest version of Cassini runs smoothly on all the latest multicore 32 and 64 bit CPUs and supports entire (reasonable) line of Windows operating systems: from Windows 2000 to Vista.

Now, whether you own an older version of our tiny but powerful UltiDev Cassini, or you never tried it - go ahead and download the latest version. If you owned old version - most of the known issues will go away (or if you had none you will be less likely to face issues in the future). If you never saw our Cassini - it's a perfect time to spend 20 minutes on something you probably will go "wow!" about. Check it out now!

Just-announced Windows Home Server is a good news for UltiDev LLC even though Windows Home Server currently is not much more than glorified Network Attached Storage and an automatic backup system. Windows Home Server is based on Windows 2003 Server and therefore does not have TV recording functionality for Media Center Edition one would expect from household server. But despite being driven by Windows 2003 Server, Windows Home Server does not seem to have web server and email server on it.

Our HttpVPN and Cassini Web Server products will make MCE attractive for every developer who can make a web-based application. To be truly useful household platform, all software for household servers should web-based and should accessible securely and reliably on Internet as well as and inside the home network. Good news for us is that we do it while Microsoft does not seem to.

I think people will feel much more comfortable when their data is stored on their own servers at home and being accessible everywhere using secure web connection, instead of having data stored on third party servers. Real "web 2.0" (God, I hate this marketing gimmick!) is not only user-generated content, but user-generated content stored on user's own servers and securely accessible from everywhere. This is what we are making happen with HttpVPN, which makes every programmer who can write ASP.NET, JSP, PHP, Perl, Python, ASP, Cold Fusion (or whatever else web development tool he/she is using) a potential winner in the huge but completely untapped market of home server software.

I feel good to be at the right place at the right time. You need to join in.

It appals me beyond any limit every time I see a commodity turned into a product. Like with Mach-150 razors with 1200 blades in it, or printer ink cartridge costing more than a printer, it is a clear-cut scam every single time. Case in point: "high-end" digital A/V cables. One of my colleagues has recently bought 9ft HDMI cable for $100. It was all fancy, gold-plated, silver wrapped cable in a very pretty package. However, although HDMI is a cable used for Audio/Video purposes, it still does exactly the same stuff as your regular 1GB Cat 5 Ethernet cable or USB cable: it moves ones and zeros. Now, even in retail CAT 5 cable costs about $0.40 per foot. Look at all the USB cables around you connecting all sorts of equipment, from digital cameras and external hard drives to keyboards and printers - can you find any of them being gold-plated and costing upward of $40? All those cables are digital yet very inexpensive while moving your files and other data without any distortions.

So if one pays more than $0.40 per foot of ANY digital cable: Ethernet, DVI, HDMI - the person is a certifiable sucker and people who sold it to him/her are shameless snake oil peddlers. Go to eBay or www.AllElectronics.com and buy the cheapest cable you can find and you will be just fine.

You can bring up as many anecdotal evidence as you want about how generic cable sucked, and then monster cable made your TV picture crystal clear, but the fact remains: bits either go through or not regardless where they travel: on commodity Ethernet cable, or on the most exclusive and expensive HDMI cable. If you don't get TV picture all distorted like satellite TV signal during heavy rain, your cheap HDMI cable works perfectly fine and your TV picture CANNOT possibly be made any better by expensive "monster" cables.

I can't wait to see what will happen when all consumer electronic components will start receiving digital A/V feeds over the air using wireless connections. I think all the high-end cable manufacturers need to start diversifying now and get busy with creating gold-plated wireless antennas costing $200 and up.
