Current Items of Interest (most recent first; occasionally pruned)

  1. Traditionally, processor technology was defined like this:
    Then CISC and RISC vendors began to add vector processing instructions to their processor chips which blurred everything
     
    1. Minicomputer / Workstation
      1. 1989: DEC adds vector processing capabilities to their Rigel microprocessor
      2. 1989: DEC adds optional vector processing to VAX-6000 model 400 (called VAXvector)
        • http://deathrow.vistech.net/~cvisors/DEC94MDS/60vaaom1.pdf (VAX 6000 Series - Vector Processor Owner’s Manual)
      3. 1994: VIS 1 (Visual Instruction Set) was introduced into UltraSPARC processors by SUN
      4. 1996: MDMX (MIPS Digital Media eXtension) is released by MIPS
      5. 1997: MVI (Motion Video Extension) was implemented on Alpha 21164PC from DEC/Compaq. MVI appears again in Alpha 21264 and Alpha 21364.
    2. Microcomputer / Desktop
      1. 1997: MMX was implemented on P55C (a.k.a. Pentium 1) from Intel
        • the first Intel offering involved 57 MMX instructions
      2. 1998: 3DNow! was implemented on AMD K-2
      3. 1999: AltiVec (also called "VMX" by IBM and "Velocity Engine" by Apple) was implemented on PowerPC 4 from Motorola
      4. 1999: SSE (Streaming SIMD Extensions) was implemented on Pentium 3 "Katmai" from Intel.
        1. this technology employs 128-bit instructions
        2. SSE was Intel's reply to AMD's 3DNow!
        3. SSE replaces MMX (both are SIMD but SSE uses its own floating point registers)
      5. 2001: SSE2 was implemented on Pentium 4 from Intel
      6. 2004: SSE3 was implemented on Pentium 4 Prescott on from Intel
      7. 2006: SSE4 was implemented on Intel Core and AMD K10
      8. 2008: AVX (Advanced Vector Instructions) proposed by Intel + AMD but not seen until 2011
        1. this technology employs 256-bit instructions
           
    Putting hyper threading aside for a moment, we first see true SMP on the desktop in 2005 with Intel's dual-core Pentium-D. Since then, the number of cores from all vendors has only gone up.
     
    But GPU (graphics programming units) take vector processing to a whole new level. Why? A $200.00 graphics card now equip your system with 1500-2000 streaming processors and 2-4 GB of additional high speed memory.
    I've been in the computer hardware-software business for a while now but can confirm that computers have only started to get real interesting again this side of 2007 with the releases of CUDA, OpenCL, etc.
  2. In September 2009, we are started to see Android-based cell phones coming into the market place. In 2010 we started to see Google's Android-based cell phone called Nexus 1

    Excerpt from NPR's "Science Friday" program 2007-11-16: I hate my cell phone. I have to admit it's not easy to use. I hate my cell phone carrier because it locks me into a system: It doesn't let me choose the cell phone I would like to use. It doesn't physically play nicely with my computer's calendar or its address book or my other tools that, ideally, would make my life easier. And if I want to change my situation, you know what that's like, if I want to move to another carrier I have to buy a new phone because that phone doesn't fit the next carrier. I have to get a new service with the limitations that are all there. It’s basically like having to start all over again in many cases. And it makes you wonder why can't they make a cell phone that lets me do what I want to do? Let me choose a provider I want to pick. The cell phone I want to pick. Wouldn't you like that too? Well we may be getting closer to that day because first Apple introduced the iPhone that basically puts a small computer in your pocket and that gives you a lot more flexibility. You're still locked into that one carrier so that's not so great. And you're still locked into the goodies that Apple wants to give you and lets you have on their [your] iPhone but last week Google, the search engine king, brought us a step closer dipping its toe into the cell phone world. And not with a full fledged gPhone as they've been calling it, but by helping to develop a set of software tools call Android that can run on many different hand sets with interchangeable parts. And that could allow more flexibility for consumers.
  3. University of Michigan electrical engineer builds chip composed of 1 kilobit nanoscale memristors
    http://www.physorg.com/news156526733.html

    How We (HP Labs) Found the Missing Memristor
    http://spectrum.ieee.org/dec08/7024
    IEEE claims "this is the greatest electronics invention of the last 25 years"

    Logic circuits that program themselves: memristors in action
    http://arstechnica.com/hardware/news/2009/01/logic-circuits-that-program-themselves-memristors-in-action.ars

    Every electronics student knows about resistors, capacitors and inductors, but HP Labs has just developed a fourth fundamental device called a memristor which is expected to revolutionize memory circuits and neural-net computers.
  4. The Software Developer's Rule:
              "Faster, Better, Cheaper." Pick any two but you can never have all three.
     
  5. Seven Mistakes Made All the Time by Most Software Development Organizations from http://www.kbcafe.com
    makes reference to companies like: Bell-Sygma, CGI
     
  6. The 2004-05 issue of Scientific American claims there are 205 million PCs in the USA incorporating switching power supplies with an efficiency of only 60-70% (so 30-40% of the power is converted to waste heat; OK in the winter but will overload cooling systems in the summer). By changing power supply design from "forced commutation" to "resonance based", the electronics industry hopes to push efficiency to 80-90%. Click Efficient Power Supplies for more details. Now if we could only get rid of those pesky linear (non-switching) power adapter cubes (wall warts).
     
  7. HyperTransport is the biggest thing in computer technology since the invention of the PCI bus. Intel has gone their own way with a variant called Quick Path Interconnect (QPI). Both these technologies were derived from a technology named Common System Interface (CSI) which was technology developed by DEC engineers for the Alpha 21264 (EV8) which was never released. The Intel technology can be found in their Core i7 processor.

SUN Solaris-11 for x86-64 (2007-04-xx) Installation Tips

Note:
1) Sun was acquired by Oracle in Jan-2010 so much information is now outdated but a few tidbits may still be of some use.
2) Click here to jump to my 2012 installation notes

  1. Click www.solaris.com to freely download Solaris-10 for the following platforms: SPARC, x86, x86-64
  2. As of 2007-04-xx you can get Solaris-11 (a.k.a. SunOS-5.11) by first navigating through this "Indiana Jones" style game...
    http://www.sun.com/playtempleofthesun (Play Temple of the Sun)
    ...while answering six "C/C++ programming questions" at the various wall consoles. If you are successful, SUN will mail you a free DVD containing "Solaris Express, Developer Edition" containing Solaris-11 along with Sun Studio 11 which is their IDE (Integrated Development Environment). It looks similar to Microsoft's IDE called Visual Studio and comes with compilers for: C, C++, and Fortran. Sun Studio 11 can invoke either Sun or GNU compilers. It is able to generate code for three hardware platforms (SPARC, x86, x86-64) running either Solaris or Linux.
  3. As of 2008-01-xx you only need to click here...
    http://www.sun.com/software/solaris/solaris-express/get.jsp
    ...then do a free download -or- request a DVD be mailed for $10.00
  4. boot the DVD then install everything on a spare drive in your PC
    1. I used a Compaq Presario SR2044NX with:
      1. 1 GB of RAM
      2. 2.8 GHz Pentium-D (two cores)
      3. 200 GB SATA Drive
      4. DVD-RW
    2. Solaris-11 has enabled both cores. Yipee!
  5. Yikes! It's only been 8 weeks and now (2007-06-06) SUN has just announced that Sun Studio 12 is available for  download.
  6. As is the case with almost every flavor of UNIX on a PC, your sound card will probably not work. So go to one of these web sites:
    1. http://www.opensound.com/download.cgi (Open Sound System is now free for personal and non-commercial use and comes with a license key that will allow you to run OSS. The license key is valid for up to 6 months at a time after which you will need to download and install OSS again. There are no time limitations or restricted functionality during the licensing period.)
    2. http://www.bolthole.com/solaris/drivers/
    3. http://www.tools.de/opensource/solaris/audio/
    4. Execute this Solaris command "prtconf" to see the hardware adapter entry points. Alternatively another utility called "prtpci" can be found on the web
    5. Other resource links
      1. http://www.bolthole.com/solaris/x86.html
      2. http://www.tools.de/opensource/solaris/
      3. http://solaris-x86.org/
      4. http://www.sunfreeware.com/
  7. Use the "Options Button" to log in using the GNOME desktop. While CDE may be more familiar to people coming from an X-Windows environment, the GNOME desktop looks a little more like Windows and includes a "cool tool" called "Network Servers" for connecting to other platforms including Windows).
  8. Now...
    1. double click on the "Developer Guide" desktop icon
    2. or alternatively...
      1. click Orange Start Button
      2. "All Applications" item
      3. "Developer Tools" item
      4. "Developer Guide" item
    3. Now click on some of the educational video hyperlinks (which is why we needed to fix the sound card)
  9. Some quick command line entries for UNIX newbies:
    Command Function
    man help
    w work display
    ps -ef process status display (e=every thing, f=full)
    ps -ef | more process status display (one page at a time)
    ps -ef | grep yada process status display but only display lines containing "yada"
    prstat process status (refreshes every 5 seconds)
    psrinfo -v processor info (v=verbose)
    ls -la directory of files (l=long, a=all)
    cat yada type contents of file "yada"
    cd yada change directory to subdirectory "yada"
    ./yada execute "yada"

Red Hat "Fedora Core 5" i386 (2006-03-xx) Installation Tips

first read the documentation:

problem #1: You've got Windows on a first hard drive (C) but you don't want to mess around with partitioning it so you install Linux on a second hard drive (D) which you will select via a BIOS boot menu. You finish the Linux installation on the secondary drive but upon first boot from that drive, GRUB can't complete Linux startup.

solution #2:  GRUB is meant to be installed on drive C (hd0) which would then be used as a jumping off point to get to D (hd1). But you wanted to keep drives C + D completely separate and so GRUB was installed on drive D (hd1) and referred to it this way by the installation software. When you boot drive D (hd1) directly from the BIOS boot menu, drive D is now known as hd0 which is not correct. What you need to do is modify the GRUB configuration file on drive D like so.

Note that GRUB uses platform neutral device names (my drives are actually known as sda and sdb)
Click here www.linuxjournal.com/article/4622 for a really good tutorial on GRUB


SUN Solaris-11 for x86-64 (2012-05-xx) Installation Tips

Note: I needed to do this so I could determine if programs SSH/SFTP/SCP had been changed since Solaris-9
  1. Solaris-11 (a.k.a. SunOS-5.11) can be installed by first downloading it from here:
    http://www.oracle.com/technetwork/server-storage/solaris11/downloads/index.html
     
  2. They only deal with ISO images so be prepared to burn a CD-ROM or a DVD  depending upon the download size
     
  3. The installation tool (at least the one for Solaris-11 11/11) is supposed to work with either 32-bit machines (x86) or 64-bit machines (x86-64) but I was never able to get it to work in 32-bit mode (the installer would always fail with message "Long Mode Not Supported") so don't waste you time unless you have a modern 64-bit capable machine.
     
  4. I had an old Compaq Presario SR5034X with a 64-bit dual core CPU (Pentium-D) sitting in my basement just doing protein-folding (while keeping dampness low) so I grabbed that machine to to install Solaris-11 (x86-64) on a second drive.
    • Problem 1: The installer was never able to find an available drive which forced me to check my BIOS settings
    • Fix 1: I noticed that the SATA1 controller mode was set to RAID so I changed it to IDE. Solaris now installed without a hitch
    • Problem 2:  there was no GUI available (just command line) and I didn't have time to do everything the old-school way
    • Fix 2: I used this procedure to get GDM (graphics display manager) installed:
  5. If you only have access to one computer, or using just one computer is more convenient, then installing a VM manager might be a better option. My main workstation is an HP e9270f quad core (Intel Core-i7 / 6 MB) running Windows-7 64-bit so I decided to give it a try.
    • So I downloaded then installed Oracle VM VirtualBox Manager from here:
      http://www.oracle.com/technetwork/server-storage/virtualbox/downloads/index.html
    • Problem 1: I get a virtual CPU error whenever I start a virtual instance
    • Fix 1: So I checked the BIOS and notice that Virtualization was turned off so I turned it on then rebooted
    • Now I was able to install the CD-ROM into a folder which the VM was treating as a pseudo hard drive
       
  6. Oracle VM VirtualBox Manager notes:
    • this software also supports other OSs like: Linux, UNIX (various flavors), Windows (various flavors), QNX, DOS, etc.
    • every time you create a virtual instance, the minimum amount of memory is set too low (the BSD template defaults to 512M) while the number of CPUs is too low (1). This will result in the installation being painfully slow and long so make sure you commit more resources to each virtual instance before you start the instance. You can always remove CPUs and Memory later.
      p.s. a quad-core with hyper-threading enabled in BIOS will present eight CPUs to the VM so you should always commit a minimum of two CPUs.

Kudos to Oracle for a virtually (no pun) painless experience.

Java: a Rosetta Stone for the internet

Java vs. JavaScript

  1. JavaScript (originally called Mocha which was later changed to LiveScript) is an interpreted object-aware scripting language invented by Netscape with some help from Sun. The code runs in your browser and is visible when you select "view source" (provided it isn't called via an include statement in the document HEAD; but you can still copy that URL then past it into the link text-box of your browser).
  2. Java is a compiled object-oriented language invented my Sun Microsystems. The Java compiler produces bytecode which can run on any computer provided a Java Virtual Machine (JVM) is installed.
  3. Except for the first 4 characters of their names, Java and JavaScript have very little in common.

Suggestions to people maintaining/reviving BASIC compilers for smaller platforms:

According to Wikipedia, BASIC was designed in 1964. The main problem with BASIC compilers nearly a half century later is there are more differences than similarities. This is partly due to the fact that this language never went through a standardization process like COBOL, FORTRAN, C and C++. The following suggestions come from HP BASIC for OpenVMS. Here is a link to their documentation files:

Comment: To make matters worse, the largest vendor of BASIC languages tools, Microsoft, made a very wise decision (IMHO) to modify Visual-BASIC-6 so it would be able to link to internet-aware software written in other languages (like C++, Java, and C#) and vice-versa. This means that VB.net now (wisely) starts every array with subscript zero; replaces BASIC's internal string data-type with the string object (found in C++, Java, and C#), etc. While this move "broke" a lot of VB6 code, most enterprising programmers looked upon this transition as a business opportunity. But I think this paradigm shift has moved the goal posts for BASIC compliers from other vendors. Now those vendors need to decide to evolve or, like the dinosaurs, be left behind.

Suggestion #1

All programs (applications) need a mechanism to signal "success/fail/whatever" to the calling program or script. By default, many BASIC programs signal "0" (if UNIX) or "1" (if OpenVMS) when the END statement is encountered.
     END
Some BASIC compilers allows the programmer to exit with a signal like this:
     END exit_code%               ! this code is sent back to the caller
while HP-BASIC does it like this:
     END PROGRAM exit_code%       ! this code is sent back to the caller
Yep, HP-BASIC uses a similar syntax to exits all block-oriented statements (END IF, END SELECT, END FUNCTION, END SUB, END WHEN, END PROGRAM, etc.)
 Suggestion #2
Anyone who has used C++ will be familiar with the exception handling statements: try, throw, catch. Anyone who ever used BASIC would be familiar with the statement ON ERROR GOTO. However, not many BASIC programmers know that some BASIC compilers also support C++ style exception handling which looks like this:
1000	on error goto common_trap	! old school exception handling
...
	when error in			! works like try
	input "input a number?", junk%	!
	  if junk% = 999 then		!
	    cause error 52		! works like throw
	  end if			!
	  status% = 0			! all is well  
	use				! works like catch
	  status% = err			!
	end when			!
	select status			!
	  case 0			! no error
	  case 50			! data format error
	  case 51			! integer error of overflow
	  case 52			! illegal number 
	  case 151			! EOF
	  case else			!
	end select			!
...
	common_trap:
	print "error "+ str$(err)
	print "line  "+ str$(erl)
	print "text  "+ ert$(err)
	input input "hit <enter> to exit"; junk$
	fini:
	end				!

Suggestion #3

All BASIC compilers should use a standard method to modify compiler action. For example, HP BASIC uses the OPTION statement to require every variable to be declared.
1000 option type=explicit	! all variables must be declared (catches programmer typos)
     declare long i%, j%	!
     if i > 0 then		! this line will throw a compile-time error
     ...
     end if			!

Suggestion #4

All BASIC compilers need a standardized way to do ISAM file i/o (sequential, relative, indexed). While it is true that HP-BASIC requires a layered product called Record Management Services (click here to see some demos), UNIX offered similar capabilities through products like:
Wouldn't it be cool if these BASIC's had built-in extensions for ISAM plug-ins and/or relational products like MySQL

SQL Etc.

"Six Sigma" vs. "ISO 9000"?

In essence, ISO-9000 requires you to: In effect, ISO 9000 up to now (but not including the Year 2000 standard which is just now getting out to the world) can be thought of as a BASIC, ENTRY-LEVEL quality program. It only consists of the basic stuff, nothing that would excite your financial people, or delight your customer base.

There is NO requirement to: Six Sigma is a data-driven approach to process improvement aimed at the near-elimination of defects from every product, process and transaction. The purpose of Six Sigma is to gain BREAKTHROUGH knowledge on how to improve processes to do things BETTER, FASTER, and at LOWER COST. Six Sigma improvements must provide TANGIBLE BUSINESS RESULTS in the form of cost savings that are directly traceable to the bottom line. ISO 9000 doesn't even begin to look at the bottom line.

xxx---xxx---xxx---xxx---xxx---xxx---xxx---xxx

Quote from a blog posting by: Narasimha Mylavarapu 

Six Sigma is a registered service mark and trademark of Motorola, Inc. Motorola has reported over US$17 billion in savings from Six Sigma to date.

What is Six Sigma?

Six Sigma is a methodology to manage process variations that cause defects and to systematically work towards managing variation to eliminate those defects.

Six Sigma at many organizations simply means a measure of quality that strives for near perfection. Six Sigma is a disciplined, data-driven approach and methodology for eliminating defects (driving towards six standard deviations between the mean and the nearest specification limit) in any process -- from manufacturing to transactional and from product to service.

Objective:

The objective of Six Sigma Quality is to reduce process output variation so that on a long term basis, which is the customer's aggregate experience with our process over time, this will result in no more than 3.4 defect Parts Per Million (PPM) opportunities (or 3.4 Defects Per Million Opportunities €“ DPMO).

Simply Six Sigma objective can be defined as to deliver high performance, reliability, and value to the end customer.

Who Started This?

The process was pioneered by Bill Smith at Motorola in 1986 and was originally defined as a below 3.4 Defects Per (one) Million Opportunities (DPMO), or put another way, a methodology of controlling a process to the point of ± six sigma (standard deviations) from a centerline. Six Sigma has now grown beyond defect control.

In addition to the Motorola, companies which also adopted six sigma methodologies early-on and continue to practice it today, are Honeywell International (previously know as Allied Signal) and General Electric (introduced by Jack Welch). The two companies have reported to have saved literally billions of dollars thanks to the aggressive implementation and daily practice of six sigma methodologies.

Recent six sigma trends lies in the advancement of the technology with integrating to TRIZ for inventive problem solving and product design

What are the costs and savings of Six Sigma?

Many people say that it takes money to make money. In the world of Six Sigma quality, the saying also holds true: it takes money to save money using the Six Sigma quality methodology. You can't expect to significantly reduce costs and increase sales using Six Sigma without investing in training, organizational infrastructure and culture evolution.

Sure you can reduce costs and increase sales in a localized area of a business using the Six Sigma quality methodology -- and you can probably do it inexpensively by hiring an ex-Motorola or GE Black Belt. I like to think of that scenario as a "get rich quick" application of Six Sigma. But is it going to last when a manager is promoted to a different area or leaves the company? Probably not. If you want to produce a culture shift within your organization, a shift that causes every employee to think about how their actions impact the customer and to communicate within the business using a consistent language, it's going to require a resource commitment. It takes money to save money.

I was tired of reading web pages or hearing people say:

"Companies of all types and sizes are in the midst of a quality revolution. GE saved $12 billion over five years and added $1 to its earnings per share. Honeywell (AlliedSignal) recorded more than $800 million in savings."

"GE produces annual benefits of over $2.5 billion across the organization from Six Sigma."

"Motorola reduced manufacturing costs by $1.4 billion from 1987-1994."

"Six Sigma reportedly saved Motorola $15 billion over the last 11 years."

The above quotations may in fact be true, but pulling the numbers out of the context of the organization's revenues does nothing to help a company figure out if Six Sigma is right for them.

What is the process sigma calculation formula?

Defects Per Million Opportunities (DPMO) = (Total Defects / Total Opportunities) * 1,000,000

Defects (%) = (Total Defects / Total Opportunities)* 100%

Yield (%) = 100 - %Defects

Process Sigma (type this formula into Excel): =NORMSINV(1-(total defects / total opportunities))+1.5

Be sure to include the Equals (=) sign. This will give you your process sigma (or sigma capability) assuming the 1.5 sigma shift.

For example if you type this into Excel, =NORMSINV(1-100/1000000)+1.5 you will get 5.22 for your Process Sigma.

Why Six Sigma and ISO 9000 as a quality system?

In essence, ISO 9000 requires you to: * Say what you do * Do what you say * Record what you did * Check on the results * Act on the difference

In effect, ISO 9000 up to now(but not including the Year 2000 standard which is just now getting out to the world)can be thought of a BASIC, ENTRY-LEVEL quality program. It only consists of the basic stuff, nothing that would excite your financial people, or delight your customer base.

There is NO requirement to: * Continually improve the process * To discover and reduce/eliminate sources of variation * To actively promote employee involvement

Six Sigma is a data-driven approach to process improvement aimed at the near-elimination of defects from every product, process and transaction. The purpose of Six Sigma is to gain BREAKTHROUGH knowledge on how to improve processes to do things BETTER, FASTER, and at LOWER COST. Six Sigma improvements must provide TANGIBLE BUSINESS RESULTS in the form of cost savings that are directly traceable to the bottom line. ISO 9000 doesn't even begin to look at the bottom line.
