Back in Februray, my blog post [A Box Full of Floppies] mentioned that I uncovered some diskettes compressed with OS/2 Stacker. Jokingly, I suggested that I may have to stand up an OS/2 machine just to check out what is actually on those floppies. Each floppy contains only three files: README.STC, STACKER.EXE and a hidden STACKVOL.DSK file. The README.STC explains that the disk is compressed by Stacker, a program developed by [Stac Electronics, Inc.]. The STACKER.EXE would not run on Windows XP, Vista or Windows 7. The STACKVOL.DSK is just a huge binary file, like a ZIP file, compressed with [Lempel-Ziv-Stac] algorithm that combines Lempel-Ziv with Huffman coding.
In my follow-up post [Like Sands in an Hourglass], I explained how there are many ways I could have tackled this project. I could either use the Emulation approach and try to build an OS/2 guest image under a hypervisor like VMware, KVM or VirtualBox, or just take the Museum approach and try taking one of my half dozen old machines, wipe it clean and stand up OS/2 on it bare metal. This turned out to be more challenging than I expected. The systems I have that are modern and powerful enough to run hypervisors don't have floppy drives, so I opted for the Museum approach.
(A quick [history of OS/2] might be helpful. IBM and Microsoft jointly developed OS/2 back in 1985. By 1990, Microsoft decided it's own Windows operating system was more popular with the ladies, and decided to break off with IBM. In 1992, IBM release OS/2 version 2.0, touted as "a better DOS than DOS and a better Windows than Windows!" Both parties maintained ownership rights, Microsoft renamed OS/2 to Windows NT. The "NT" stood for New Technology, the basis for all of the enterprise-class Windows servers used today. IBM named its version of OS/2 version 3 and 4 "WARP", with the last version 4.52 released in 2001. In its heyday, OS/2 ran the majority of Automated Teller Machines (ATMs), was used for hardware management consoles (HMC), and was used worldwide to run various Railway systems. After 2001, IBM encouraged people to transition from Windows or OS/2 over to Java and Linux. For those that can't or won't leave OS/2, IBM partnered with Serenity Systems to continue OS/2 under the brand [eComStation].)
Working with an IBM [ThinkCentre 8195-E2U Pentium 4 machine] with 640MB RAM and 80GB hard disk, a CD-rom and one 3.5-inch floppy drive, I first discovered that OS/2 is limited to very small amounts of hard disk. There are limits on [file systems and partition sizes] as well as the infamous [1024-cylinder limit] for bootable operating systems. Having a completely empty drive didn't work, as the size of the disk was too big. Carving out a big partition out of this also failed, as it exceeded the various limits. Each time, it felt the partition table was corrupted because the values were so huge. Even modern Disk Partitioning tools ([SysRescueCD] or [PartedMagic]) didn't work, as these create partitions not recognizable to OS/2.
The next obstacle I knew I would encounter would be device drivers. OS/2 comes as a set of three floppy diskettes and a CD-rom. The bootable installation disk was referred to affectionately as "Disk 0", then Disk 1, then Disk 2. Once all drivers have been loaded into memory, then it can start looking at the CDrom, and continue with the installation. In searching for updated drivers, I came across [Updated OS/2 Warp 4 Installation Diskettes] to address problems with newer display monitors. It also addresses the 8.4GB volume limit.
The updates were in the form of EXE files that only execute in a running DOS or OS/2 environment, expanded onto a floppy diskette. It seemed like [Catch-22], I need a working DOS or OS/2 system to run the update programs to create the diskettes, but need the diskettes to build a working system.
To get around this, I decided to take a "scaffolding" approach. Using DOS 6 bootable floppy, I was able to re-partition the drive with FDISK into two small 1.9GB partitions. I have the full five-floppy IBM DOS 6 set, I hid the first partition for OS/2, and install the DOS 6 GUI on the second partition. I went ahead and added a few new subdirectories: BOOT to hold Grub2, PERSONAL to hold the data I decompress from the floppies, and UTILS to hold additional utilities. This little DOS system worked, and I now have new OS/2 "Disk 1" and "Disk 2" for the installation process.
(If you don't have a full set of DOS installation diskettes, you can make due with "FORMAT C: /S" from a [DOS boot disk], and then just copy over all the files from the boot disk to your C: drive. You won't have a nice DOS GUI, but the command line prompt will be enough to proceed.)
Like DOS, OS/2 expects to be installed on the C: drive. I hid the second partition (DOS), and marked the first partition installable and bootable. The OS/2 installation involves a lot of reboots, and the hard drive is not natively bootable in the intermediate stages. This means having to boot from Disk 0, then putting in Disk 1, then disk 2, before continuing the next phase of the installation. I tried to keep the installation as "Plain Vanilla" as possible.
I had to figure out what to include, and what to exclude, and this involved a lot of trial and error. For example, one of the choices was for "external diskette support". Since I had an "internal diskette drive", I didn't think I needed it. But after a full install, I discovered that it would not read or write floppy diskettes, so it appears that I do indeed need this support.
OS/2 supports two different file systems, FAT16 and the High Performance File System (HPFS). Since my partition was only 1.9GB in size, I chose just to use FAT16. HPFS supported larger disk partitions, longer file names, and faster performance, none of which I need for these purposes.
I thought it would be nice to get TCP/IP networking to work with my Ethernet card. However, after many attempts, I decided against this. I needed to focus on my mission, which was to decompress floppy diskettes. It was amusing to see that OS/2 supported all kinds of networking, including Token Ring, System Management, Remote Access, Mobile Access Services, File and Print.
Once all the options are chosen, OS/2 installation then proceeds to unpack and copy all the programs to the C: drive. During this process, IBM had informational splash screens. Here's one that caught my eye, titled "IBM Means Three Things" that listed three reasons to partner with IBM:
You might wonder how these OS/2 splash screens, written over 10 years ago, can appear almost identical to IBM's current [Smarter Planet] campaign. Actually, it is not that odd. IBM has been keeping to these same core principles since 1911, only the words to describe and promote these core values have changed.
To access both OS/2 and DOS partitions, I installed Grand Unified Bootloader [Grub2] on the DOS partition under C:/BOOT/GRUB directory. However, when I boot OS/2, I cannot see the DOS partition. And when I boot DOS, I cannot see the OS/2 partition. Each operating system thinks its C: drive is the only partition on the system.
Now that I had OS/2 running, I was then able to install Stacker from two floppy diskettes. With this installed, I can compress and decompress data on either the hard disk, or on floppy diskettes. Most of the files were flat text documents and digital photos. After copying the data off the compressed disks onto my hard drive, I now can copy them off to a safe place.
To finish this project, I installed Ubuntu Linux on the remaining 76GB of disk space, which can access both the OS/2 and DOS drives FAT16 file systems natively. This allows me to copy files from OS/2 to DOS or vice versa.
Now that I know what data types are on the diskettes, I determined that I could have decompressed the data in just a few steps:
However, now that I have a working DOS and OS/2 system, I can possibly review the rest of my floppy diskettes, some of which may require running programs natively on OS/2 or DOS. This brings me to an important lesson. If you are going to keep archive data for long-term retention, you need to choose file formats that can be read by current operating systems and programs. Installing older operating systems and programs to access proprietary formats can be quite time-consuming, and may not always be possible or desirable.
In preparation for my [upcoming trip to Australia and New Zealand], I decided to upgrade my smartphone. My service provider T-Mobile offered me the chance to try out any new phone for 14 days for only ten dollar re-stocking fee. For the past 16 months, I have used the Google G1 phone. This is based on a storage-optimized Android operating system, based on open source Linux, with applications processed in a storage-optimized virtual machine called Dalvik, based on open source Java. According to Wikipedia, Android-based phones have #1 market share [outselling both BlackBerry OS and Apple iOS phones]. There are over 70 different companies using Android, driven away from the proprietary interfaces from Apple, BlackBerry and Microsoft.
Since I was already familiar with the Android operating system, I chose the Samsung Galaxy S Vibrant. I liked my G1, but it had only a small amount of internal memory to store applications. The G1 supported an external Micro SDHC card, but this only was used for music and photos. There was no way to install applications on the memory card, so I found myself having to uninstall applications to make room for new ones. By contrast, the Vibrant has 16GB internal memory, plenty of room for all applications, and supports Micro SDHC up to 32GB in size. My model can pre-installed with a 2GB card, of which 1.4GB is consumed by James Cameron's full-length movie Avatar. On the G1, swapping out memory cards was relatively easy. On the Vibrant, you have to take the phone apart to swap out cards, so I won't be doing that very often. I will probably just get a 32GB card and leave it in there permanently.
(FTC disclosure: I work for IBM. IBM has working relationships with Oracle, Google, and lots of other companies. IBM offers its own commercial version of Java related tools. I own stock in IBM, Apple, Google. I have friends and family who work at Microsoft. My review below is based entirely on my own experience of my new Samsung Galaxy S Vibrant phone. Samsung has created different models for different service providers. The T-Mobile Vibrant is an external USB storage device with telephony capabilities, comparable to the AT&T Captivate, Verizon Fascinate, or Sprint Epic 4G. The majority of mobile phones in the world contain IBM technology. This post is not necessarily an endorsement for Samsung over other smartphone manufacturers, nor T-Mobile over other service providers. I provide this information in context of storage optimization, state-of-the-art for smartphones in general, and disputes related to software patents between companies. I hold 19 patents, most of which are software patents.)
When Oracle acquired Sun Microsystems, it inherited stewardship of Java. Java is offered in two flavors. Java Standard Edition (SE) for machines that are planted firmly on or below your desk, and Java Micro Edition (ME) for machines that are carried around. Most Java-based phones limit themselves to Java ME, but Google decided to base its smartphones on the more powerful Java SE, but then optimize for the limited storage and computing resources. These two levels of Java have radically different licensing terms and conditions, so Larry Ellison of Oracle cried foul. On The Register, Gavin Clarke has an excellent article with details of the Oracle-vs-Google complaint. Daniel Dilger opines that Oracle [might kill Google’s Android and software patents all at once]. Fellow blogger Mark Twomey (EMC) on his StorageZilla blog, argues that [it's not about Android phones, but Android everything].
My Vibrant is roughly the size of a half-inch stack of 3x5 index cards in my hand. In my humble opinion, the problem is the grey area between mobile phone and the desktop personal computer. Laptops, netbooks, iPads, tablet computers, eBook readers, and smartphones fall somewhere in between. At what point do you stop licensing Java SE and start licensing Java ME instead?
Let's take a look at all the stuff my new Samsung Vibrant can do, and let you decide for yourself. I have 140 applications installed, which I can access alphabetically. I also have up to seven screens which I can fill with application icons and widgets to simplify access. The screen measures about 4 inches diagonally. Click on each image below to see the full 480x800 resolution.
Just in case I switch to a local SIM card while abroad in another country, I asked T-mobile to unlock my phone, which they happily did at no additional charge. For example, while I am in Australia, I can either leave my T-Mobile USA chip in the phone, and pay roaming charges per minute, or I can purchase a SIM chip from a local phone company with pre-paid minutes. This often includes unlimited free incoming calls to a local Australian phone number, and voicemail.
Unlocking the phone to use different SIM cards is different than "jailbreaking", a term that refers to Apple's products. For Android phones, jailbreaking is called "rooting", as the process involves getting "root" user access that you normally don't have. The only reason I have found to have my phone "rooted" was to take these lovely screen shots, using the "Screen Shot It" application. This is another application that I paid for. I used the free trial for a few screenshots first to check it out, liked the results, and bought the application.
So, this new smartphone looks like a keeper. I got a screen protector to avoid scratching, and a two-piece case that snaps around the phone to give it more heft. All my chargers are "Mini USB" for my old G1 phone, and this new Vibrant phone is "Micro USB" instead, so I had to order new ones for my car, my office, and for my iGo (tip A97).
This review is more to focus on the fact that the IT industry is changing, and what was traditionally performed on personal computers are now being done on new handheld devices. Android provides a platform for innovation and healthy competition. Let's all hope Oracle and Google can work out their differences amicably.

In addition to dominating the gaming world, producing chips for the Nintendo Wii, Sony PlayStation, and Microsoft Xbox 360, IBM also dominates the world of Linux and UNIX servers. Today, IBM announced its new POWER7 processor, and a line of servers that use this technology. Here is a quick [3-minute video] about the POWER7.
While others might be [Dancing on Sun's grave], IBM instead is focused on providing value to the marketplace. Here is another quick [2-minute video] about why thousands of companies have switched from Sun, HP and Dell over to IBM.
Well, it feels like Tuesday and you know what that means... "IBM Announcement Day!" Actually, today is Wednesday, but since Monday was Memorial Day holiday here in the USA, my week is day-shifted. Yesterday, IBM announced its latest IBM FlashCopy Manager v2.2 release. Fellow blogger, Del Hoobler (IBM) has also posted something on this out atthe [Tivoli Storage Blog].
IBM FlashCopy Manager replaces two previous products. One was called Tivoli Storage Manager for Copy Services, the other was called Tivoli Storage Manager for Advanced Copy Services. To say people were confused between these two was an understatement, the first was for Windows, and the second was for UNIX and Linux operating systems. The solution? A new product that replaces both of these former products to support Windows, UNIX and Linux! Thus, IBM FlashCopy Manager was born. I introduced this product back in 2009 in my post [New DS8700 and other announcements].
IBM Tivoli Storage FlashCopy Manager provides what most people with "N series SnapManager envy" are looking for: application-aware point-in-time copies. This product takes advantage of the underlying point-in-time interfaces available on various disk storage systems:
For Windows, IBM FlashCopy Manager can coordinate the backup of Microsoft Exchange and SQL Server. The new version 2.2 adds support for Exchange 2010 and SQL Server 2008 R2. This includes the ability to recover an individual mailbox or mail item from an Exchange backup. The data can be recovered directly to an Exchange server, or to a PST file.
For UNIX and Linux, IBM FlashCopy Manager can coordinate the backup of DB2, SAP and Oracle databases. Version 2.2 adds support specific Linux and Solaris operating systems, and provides a new capability for database cloning. Basically, database cloning restores a database under a new name with all the appropriate changes to allow its use for other purposes, like development, test or education training. A new "fcmcli" command line interface allows IBM FlashCopy Manager to be used for custom applications or file systems.
A common misperception is that IBM FlashCopy Manager requires IBM Tivoli Storage Manager backup software to function. That is not true. You have two options:
IBM FlashCopy Manager is an excellent platform to connect application-aware fucntionality with hardware-based copy services.
