I am catching up on the first two days (Chrome browser did not work yesterday).  The presentation and material are really high quality!

What I am missing is the FMEA.  This is a must requirement for product development.

Iron

We prototype our firmware on FPGA hardware emulator

Iron

Thanks Jacob, I did look at your web site I must have over looked it.

Iron

@1yljunkmann - I apologize but I'm not sure what you mean. I just hit the play button on today's audio bar above and am hearing today's lecture.

@StephT - thanks for the link!  I'm going to look into it

Iron

Now that today's course is over I am getting sound but it is sound from a sourse other than yours. 

Again what's changed and what can I do aboiut it?

junkman

@Jacob. I would expect today the application of Software design priciples to the Real Worldish example from yesterday lecture

Iron

I'm still curious about the pineapple though :-)

Iron

StephT - thanks for the link!  I'm going to serious consider doing that class...

Iron

ah yes, type-checking in C.

 

Iron

OK, this chat has degenerated into a bunch of engineers trying to fix (or break) the chat app :-)

Iron

first one to find the escape sequence wins a price

 

Iron

Well, gotta get back to it.  Thanks all for your insight and look forward to a another good presentation tomorrow!

Iron

Hi all,

First, I hope I'm not reposting the following as I haven't had time to read all your postings...

FYI : Keeping this courses topic, for anyone interested in the SWEBOK 3.0 (Software Engineering Body of Knowledge), the IEEE Computer Society and University of California Irvine have teamed up to host a FREE  Massive Open Online Course (MOOC); see the details & register here :

http://www.computer.org/portal/web/certification/courses/MOOC?lf1=101725465e170116074826d17004742

These are online (YouTube) videos ; the course started last week, but can catch up... + you get a PDF copy of the book.

The three-week online course, "Stop Writing Embarrassing Software Code: SWEBOK Version 3.0 Best Practices for Software Development," will be taught by Don Shafer, IEEE Computer Society Vice President of Professional Activities and a distinguished global expert in the practice of software engineering.

 

Iron

I agree, you can do a lot in C for OO; however, I found that C+ enforces some things that would help me break some really bad habits here -- like stricter type checking of enum.  So I have a little ulterior motive besides just OO.  :-)

(I also hate how this chat auto-deletes the second ' '.)

Iron

This chat won't take two "+" signs in a row!!

Iron

@jacob The link you just mentioned gave me the templates from yesterday.  Are there new ones for today?

Iron

that should read "overhead of C+ ." obviously.

Iron

Actually I've found one can do a lot of object-oriented programming in C, without the overhead of C+ .  After all, the start of the OO paradigm was by Bertrand Meyer and was all written in C. (Oops, I guess I'm dating myself, huh?)

Iron

Good lesson

How to save time and money...

Iron

Thanks for the lecture and the tools

Iron

@cghaba, I'll take a look at that one, too.  Thanks.

Iron

@Tocard -- yes, 2002.

Iron

@Jacob, thanks for the tip.  I'm trying to get my team to move towards C+ and OO thinking now.  But we're using C and probably will be for awhile.

@nneff, the one I found on Amazon is (c) 2002.  Is that the latest edition you're aware of?

Iron

@CurtD -- see today's slide 18

Iron

The templates can be found here

 

http://beningo.com/index.php/design-cycle/171-mastering-the-software-design-cycle-templates.html

Blogger

What about Embedded System Building Blocks by Jean Labrosse?

Iron

thanks for the info on the tools

 

Iron

Thanks you Jacob

I can't find the templates you were talking about yesterday and today.

Iron

@jacob: how do you go about implementing design patterns, especially in c, i asume some patterns arent just made to be implemented effectively in embedded contexts on c?

 

Iron

@devmo We also use pclint here.  It is not free but it has paid for itself many time over in finding bugs which were not testable.

Iron

@Devmo -- check out SpLint or CppCheck -- both free

Iron

The Design Patterns book by Bruce Powel Douglass is really good but be warned that it does try to do design patterns of object oriented programming in C which can be a bit dizzying

Blogger

@LG -- answer depends on which open-source license is used by the code you're using.

Iron

Technical Problem: I accidentally clicked on a date in the "chat", (attempting to select and copy valuable text), and it loaded another page in the same browser window. When I clicked Back, the entire conversation started loading, ~1.5 messages per second. I'm effectively out of the conversation.

Iron

My lunch is over, I'm looking forward to tomorrow.

Iron

Good lecture.  Looking forward to tomorrow.

Iron

Thanks - nice job today.

Iron

@devmo, I usually use PCLint for my static analysis which isn't free.  I would have to look to see if there are any good ones for linux.  Most of my firmware development is done in a PC environment, minus my work with Android.

Blogger

@nneff, Thanks!  I'll check it out.

Iron

@Jacob In the case of using Open Source that requires release... would that cover just modification/addition of that open source module or any module you write that interfaces to it?

Iron

@K-dog I won't be talking about version control in these lectures.  I believe I talked about them for a bit in the Design News webinar series I did in November.  

Blogger

@Tocard -- Real-time Design Patterns, by Bruce Powel Douglass, ISBN-13: 978-0-201-69956-2

Iron

I mostly use python, subversion, and C.

Iron

I agree with D.Jack on that one.  

Blogger

@jacob: do you have a tool recomendation for static analysis in c? perhaps one thats free even?

 

Iron

@Jakob. It would be good if after you prove the model with matlab and write your own code, to match the two so the next time be able to generate from model your previously written code.

Iron

@BAdonis, it depends I believe on the GPL license associated with it.  Some code is free with no strings attached but others require release of any code associated with the open source code.

Blogger

@BAdonis You need an attorney, not an engineer.

Iron

Any discussion planned for "version control" tools (e..g ClearCase, Subversion, etc)?

Iron

@nneff ok will definitly check those out as well . Budgets are tight though so I may stick with the QM

Iron

Devmo, I use C for 80% of what I do.  Then I use python, java and C+ for the remainder.

Blogger

like e.g. 50% C#, 30% java, 10% scripting stuff etc

 

Iron

@Jacob, can you recommend any books or websites that dive into design patterns that are geared towards (have examples primarily for) embedded systems?

Iron

@Jacob, Does it matter if one uses open source code which then later becomes proprietary? Would one still run the risk of leasing the code?

Iron

@ Jacob: what programming languages do you use by what percent of your total work?

 

Iron

Thanks Jacob, Charles, and all involved. Looking forword to tomorrow's Lecture

 

Iron

When I have wroked with autogenerated code in the past I have found that running a c code beautifier is a good start to make the code legible. From theere i swas a matter of disecting all of the pointer dereferences.

Iron

the Audio and chat are not functional today

Iron

@Kaddaem -- and if your company will pay for the tools, both Rhapsody and MathWorks' Stateflow are also excellent tools for developing executable state machines.

Iron

@nneff thanks for the link will check it out

Iron

yes the same for me here

Iron

I was expecting something more usefull or structured... I don't have ADHD, this is not useful.

Iron

Technical issue - The live chat is very laggy for me.....it takes a while after my entering a post before it shows up....and other's comments seem delayed also.  Much worse than other classes I've attended here.

Iron

78RPM, I like your comment.  I'm not involved in much open source development but some of the open source code I have used has scared me.  From the fact that I feel it tends to be poorly documented and difficult to understand if you need to dig into the details.  

In most large open source design cycles I believe there is still a head that decides which codes branches and code make it into the main.

Blogger

Autogenerated code is always hard to read for human.

Iron

@LG, You were expecting a phone call?

Iron

@LG This IS the live chat.

Gold

Yes, LG. This is the live chat.

Blogger

@Kaddaem -- check out http://www.state-machine.com/qm/.  It's free and well documented in his book on state charts.

Iron

@LG: Yes, this is the live chat

Blogger

Question: Is this the "live chat" or am I missing a link somewhere?

Iron

A Good one! Thanks for your presentation and hard work.

Iron

@Jacob (my question is about process rather than methods for documenting or capturing the design, which you covered very well in your presentation!)

Iron

HA !!  I was expecting AUDIO!  Duh..

Iron

Detail design of subprocesses should be capable to be paralleled with architectural design.

Iron

ElRoy, I haven't used matlab autocode feature to compare with the application development.  I've found that machine generated code is usually far from human readable code!  I generally use Matlab to prove the model and then hand code the model.

Blogger

YOU are one of the best lecturers I've ever attended.

Had you taught Statistics, I likely wouldn't have slept through class.

Iron

@Jacob are there any formal state diagram tools out there that you can use for design or do you recommended any

Iron

this is the live chat

Iron

@nfjensen - this is the live chat!

Iron

@nfjensen,  you just typed into th elive chat.  This is it.

Gold

And thank you, Jacob!

One comment - you're going pretty fast through all this stuff.  But of course you have a lot to cover, too.  I thought you had 45 minutes allotted for the presentation (not just 30), then the remainder for questions?  I for one really could go for 45.

Iron

?? Jacob, How can or how do Open-Source communities adhere to a design process?  Most such communities look more like a flock of geese rather than a swarm or glaring of cats.  How is that possible?

Gold

What type of Diagrams can we use for a MultiCore MultiTheraded System with lots of InterThread communication happening using Events, Message Q's etc.,

Thanks Jacob,

in your reference to Matlab in software design quality slide 14, do you ever use autocoding from Matlab to compare answers with on purpose application software?

 

Iron

My audio link kept stopping every few minutes and I had to click the start arrow to continue was this only my issue.

Iron

where is the live chat?

Iron

Thanks Jacob and Chuck

Iron

We use several varieties of simulators, MathLab, Simulink and prototypes.

Very good presentation, thank you.

Iron

Jacob how can we represent in our design a MultiCore MultiThreaded System ?

Thanks, looking forward to tomorrow

Iron

Thank you Jacob, Chuck and Digikey.

Iron

Thanks Jacob for sharing your knowledge

 

Iron

@Jacob -- do you know of any formalized process for detailed design development that would be parallel to architectural design process (such as SEI's ATAM, ARID, etc.)? There seem to be these well-defined processes for developing architectures, but not comparably detailed, documented, and formalized processes for detailed design. I find that the SWEBOK has only a cursory discussion of process methodologies for detailed design. (I haven't yet got the book they reference -- 4* -- however.) Any suggestions?

Iron

@Jacod great talk and followup to yesterdays

Iron

what complexity do you write your code to?

Iron

Tank you Jacob! Thank's DigiKey!

Iron

Thank-you Jacob and Design News!

Iron

Thank you Jacob. Wonderful presentation!

Iron

Very good session Thank you

Thanks another good lecture.

Iron

Good lecture thanks

Iron

Good presentation. Thank you.

Was traveling yesterday - any way to hear the presentation fro then?

 

Iron

Thanks for your attention everyone!

Blogger

Thank you very much.

Iron

Jacob, thank you for today's presentation

Iron
Tools Test, trial and error. Debug with h/w.

Thanks,

DN.DK,Jacob,Charles

Iron

So I have a question..... What's with the pineapple?

Iron

thanks for the presentation, it´s a huge topic, specially when it comes to different types of archs and design approachs

Iron

I believe teh formal document for MSC is ITU-T Z120 if you want a well define dnotation.

Iron

Thanks Jacob, Chuck & Digi-key!

Iron

Thank you again for the presentation

Thank you Jacob. Good lecture.

Gold

various simulators (Modelsim, etc), TDD

Iron

We document design using UML and do design reviews. Build some prototypes to test concepts.

Iron

Or the old,

The sooner we fall behind, the more time we'll have to catch up.

 or

"Weeks of coding can save you hours of planning."

Iron

Prototyping of risky elements, knowledge, experience

 

Iron

None before code is written. The specification includes data before and after the module works on it.

Iron

UML software design tool

Iron

used design reviews and incremental dev/test cycles

Iron

Have used simulink, Excel and software emulators.

Iron

Have used design reviews, prototypes and simulation when tools were available

Iron

Design docs plus a review meeting.

for data driven designs the DB is generated by case tools fo sql.

Chart tool for clarity of layout plus review.

Iron

This discussion reminds me of the quote: "We'd better hurry up and start coding, there are going to be a lot of bugs to fix!"

Iron

Make functional diagrams to identify requirements and interfaces.

Iron

Simulation of algorithms if possible 

Iron

Simulatition or Emmulation

Iron

Self developed spread sheet tools.

Iron

simulation and prototype

Iron

tools--previously testing the hell out of it.  Now we're moving to MathWorks tool-suite for Model-based Development, which would be using Simulink Verifier and related tools.

Iron

design reviews, proto& simulation

Iron

None before the code is started. The specification includes data before and after the module works on it.

Iron

Design reviews are also used but not as rigourous.

Do you really need simulation software?

 

Iron

Design review and prototyping

Iron

we don't really use tools. We use the concept of Agile or Sprint Planning and have bi-weekly meetings

Iron

I don't know because I don't work in software development. But my view from the outside is that design reviews are not thorough enough because there are significant problems during and after development is complete.

Iron

Past experience/existing code; starting to use LabVIEW.

Iron

prototypes , tech reviews then design reviews

 

Iron

Reviews, simulation, prototype

Iron

Simulation, test cases, prototyping

Iron

UML Design Simulation Validation tools.

We use simulations on development platforms.  Risky but some basic operation is verified.

Iron

Some of our "scientists" use MATLAB to confirm the algorthims before they are implemented in C+ .

Iron

edit, debug, correct, repeat

Iron

Mostly "test - fix - test"

Iron

simulation and static analysis

prototyping and reviews are the most effective way to achieve a quality design, static analysis help and so the simulations but the first two are on my top list

Iron

Design reviews and prototyping

Iron

We rely heavily on software models.

We sometimes do design reviews....not as often as we should though.  Sometimes we just talk with our peers informally.  Some customers like to review these sorts of things at various stages too.

Iron

My projects don't really lend themselves to proving the design is correct.

Iron

We use design reviews.

Iron

Code reviews, static analysis, unit tests.

Iron

Modeling of critical areas using spreadsheet and math tools

Iron

uml, walkthrus, ttrace

Iron

Simulink Model Based Design.

Iron

Question: What types of tools do you use to ensure that your design is correct?

Blogger

What is the "best method" for running a software design review?

one more item to be added to the list for SW Quality is SCALABILITY

state machine, multitreaded designs, layered tasks

Iron

I think it fits in General

Iron

typically general, distributed

Iron

Have also worked with state machine method.

Iron

mainly general structure

Wide range of desing done here from C/S to distributed -- mostly distributed. Use word Processors and charting to build architecture. Use Lucid Chart now for high level design and data design and data flow -- at arch. level. At practical level I use a CASE tool for dtat tables and data flow.

For designing the program layers and modules I use charting -- have again switched to Lucid Chart for this. Detailed description of modules is syill in a WP -- like you.

Iron

What was the title of the other webinar on Software Architectures?

Must minimize the interrupt handler software

Iron

We have more of a layers structure with some interrupt driven state machines.

Iron

interactive distributed systems.

Iron

I think it would be classed a MVC

Iron
@ioverholt Same here
Iron

Typically a layered approach.

Iron

layered and MVC combined architecture.

which slide are we on ?

 

General structure as well here

 

Iron

Generally depends on the product and the customer requirements.  Most of our applications are relatively simple.

 

Iron

General, distributed, and Interactive

Iron

General structure typically used

multi-threaded process-control

Iron

that depends on the project: I've used client-server for distributed system, layered structure for embedded system and MVC for GUI (windows application mostly based on WPF)

Iron

Modular systems including making independent H/W plus S/W elements that operate upon command.

Iron

in embedded systems i prefer the layered architecture

Iron

Usually a state machine architecture

Layered, MVC and State Machine

Iron

arch: we're on a single micro.  In a simple RTOS we have tasks for each major logical system.  Each task talkes to a driver which runs the HW via a HAL.

Iron

Distributed systems and General structure

Iron

Generally state machines

Iron

usually a simple layered structure

multi-threaded process-control

Iron

Most of the time when we do any design documents, they look an awful lot like your diagram on slide 8 - layered.

Iron

Not much.  given general guidelines and then code.

Iron

mostly distributed systems

Iron

Genral - Layered structure

Iron

Simple layered structure

Iron

Architectures are both layered and client-server.

Iron

We are using mostly distributed architecture.

Iron

I have no idea. I am an analog power hardware engineer. I am here to learn a bit about the other side...

Iron

General structure - layers.

Iron

Typically a layered approach.

Iron

General, distributed, and Interactive

Iron

Architectures:  layers and pipes

Typically use a layer type structure

Iron

Typical layered structure.

Iron

distributed and layer

Iron

General Structure is used in our institute

Iron

I'm working more with Distributed systems

Iron

I design a State Machine before coding.

Gold

Usually implement layer structure.

Iron

Mostly layered structure.

Iron

General layered structures as well as client server

Iron

Had a short period of employment where the president of the company told me all I needed to do design work was a pencil, and reviewd the work daily.  Luckily it was a short period.

Iron

Top-Down Structure for design of code.

 

Iron

Question: What types of software architectures do you typically use?

Blogger

Depending on complexity I could spend a week or several months working on the design before any real coding starts.

Iron

Most of our architecture is a big ball of spaghetti.

Iron

agree with @dpalu2, even to reduce future bugs, but sometimes it's seen as a waste of time since the "coding" phase looks like the real code and the difficulties that arises later on leave the project leaders with a big question mark in their faces

 

Iron

Varies how much is new to me

 

Iron

approximately 30% design time

 

Iron

 varies... depending on system.

Iron

about 30% design time

Iron

Some diagrams in PowerPoints will help.

Iron

In previous companies where I was team lead, we'd spend 30-35% of the total time on determining architecture and top-level design, another 10% on detailed design (closely linked with coding), and as a result relatively little time on testing. At current company, I inherited a largely designed product that we spent about 20% of our time re-designing and another 40% of our time testing. I much preferred the former approach!

Iron

Depends on application and schedule

Iron

I'm old-fashioned and still use flow charts for major blocks of code and then build (or re-use) the modules

Iron

I am the only one who doesn't spend all that time... Agree with bmoertel

 

Iron

None if you go by managements schedule

 

Iron

About 1/2 the design time is currently being done before the coding starts.

Iron

I immediately put together a series of stubs that I fill in later with actual code.

Iron

Ans:  Varies based on complexity.  Reuse ect...  maybe 10%

Iron

Several weeks, depending on the application.

Iron

Varies but usually too little.

Iron

Seems like design and building happen simultaneously

Iron

In my experiece, the longer you spend working on the design the shorter time you will write code/debug/test.. We have daily short meeting in our group and we are all informed of what the others are working on.. at least 25% is spent planning

 

Iron

I spend it about 15~20% time on design.

Iron

It depends on the project from 10% to 50%

Iron

Try to spend 50% on design.

Iron

Audio Problems: My Company BLOCKS streaming audio via a "NetNanny".

Up unitl this week, I could skirt around that by using Chrome. But no more. Something changed....

Having an "audio partner" using a website named "BlogTalkRadio" makes it very easy for the coprporate NetNanny to block!

Iron

there is not issue with chrome. I can play other webpages with audio

Very little; hard to quantify.

Iron

Depends of requirements

Iron

We spend a few weeks define the product and interface spec's and then begin coding in the waterfall model.

Iron

Very little on design; we jump right in.

Iron

Charles Murray: Never enough!

 

I spend probably 10% of overall design time for design layout

Iron

I spend about 1/3 of my time on design

Gold

Depending on application 2 - 6 weeks

 

Iron

Not enough time spent planning and working out the design IMO. One of the things I'm trying to improve in my group.

That really depends on the application, but a significant amount usually

Iron

Time to design as to code. Twice as long to design as to code.

Iron

What's changed?  I had excellent sound yesterday.....today nothing

Junkman

Question: How much time do you spend working out the design of the software before you start building the software?

Blogger

Apparently there is a known (recent) issue with Chrome.  It is recommended to use Firefox until solution has been found.

Iron

@FerTrujillo, Thanks, clicking the play button revives the sound. -- every three seconds

Gold

Firefox 27.0.1 works perfect even on slow connection.

Iron

that's right FerTrujillo.

Iron

How IE works on my system depends on how many applications I have running.  But even when its ok it still drops occasionally.

Iron

I switched to IE from Chrome and I have audio

Iron

forget it, on IE its still cutting, have to press play every 10 seconds.. or less

No audio after intro with Chrome...

 

Iron

working on IE, still kind of annoying, I dont like IE

hi nothing is working on chrome

 

Audio is very good for me without any breaking off.

Iron

Hi from Ayer. I log out of Chrome and using IE is working.

Iron

Mine is working fine, using FF, though audio is quite muffled

Iron

I haven't heard the word "flowchart" in awhile but I like it!

Iron

Just got audio up - what slide are we on?

Iron

I tried Chrome, FF, and IE.  No luck on any of them.  This problem is not which browser we use.  It has to be something else.
I guess Blog Talk Radio doesn't use good software design principles.

Gold

Audio only working intermittently with IE 8

Hello from Orange county.

Hello all from Castle Rock Colorado.

It not start at 20:00 CET?

Iron

Firefox doesn't work either.  I get three seconds of audio, then silence for 20 seconds or so.

I'm having the same problem as yesterday using Chrome.

I was able to listen to the archived version later, but not while live...

Iron

heard the entry blast, then the audio died - google chrome

Helo everyone - I am experiencing the problem with Chrome again. If you are too, please try using FF. FF is working perfectly for me.

Greetings from Plymouth, MN

Iron

Hello from California.

Iron

Hello from Toronto, Ontario!!

Iron

yes, that would be great, every webinar has a test page where you can test audio

Iron

Hi all -Audio is live! If you don't see the audio bar at the top of the screen, please refresh your browser. It may take a couple tries. When you see the audio bar, hit the play button. If you experience audio interruptions and are using IE, try using FF or Chrome as your browser. Many people experience issues with IE. Also, make sure your flash player is updated with the current version. Some companies block live audio streams, so if that is the case for your company, the class will be archived on this page immediately following the class and you can listen then. People don't experience any issues with the audio for the archived version.

I can't see the audio bar.

Iron

Hello from Rochester...  Hopefully audio will work today.  Was unable to get time to review the archive.

Iron

 

Another option for Chrome problems is to replace the 33 update with the older 32 update that works with blogtalkradio. Discussion at:

Hello from Central Florida

Iron

Howdy.  Looking forward to the rest of these classes.

However, I second the recommendation from yesterday to have some pre-class streaming so that people can get audio problems sorted out.  Probably less important today than yesterday, but it would be a great idea for all sessions.  Thankfully I haven't had any problems, but every class that I come to, there are people who do have trouble.  A few extra minutes to test connection, player, etc. would really help.

Hi everyone from Azcapotzalco, Mexico, DF

Iron
jrc_fw, IE was the only browser that worked for me yesterday, so you might be fine
 
Iron

The archived versions don't have the same problems that the live stream encounters, so you aren't able to test it by listening to yesterday's archive. While I have been assured that the problem has been resolved, an option is for you to have both Chrome and FF open and ready in case there happens to be a problem with Chrome today.

I thought most people had no problems

I had to switch computers and the problems

were mine,

 

Iron

 

The archived audio worked fine yesterday while the live audio failed.

 

Iron

@typn, try an archival lecture, ok

Iron

 

can we test the audio fix while we wait?

 

Iron

Good morning everyone - A fix is in place so that the problem that occurred with Chrome yesterday shouldn't happen again. If anyone is curious as to what the problem was, a new version of Chrome was deployed and it broke/disabled some Flash functionality. BlogTalkRadio (the company who we partner with for the audio stream) has released a fix which forces Chrome browsers to use a different version of the audio player now (HTML5 instead of Flash).

Good evening from Iasi, Romania

Iron

Did the Chrome issue get fixed, my company only allows IE and Chrome as browsers

You are eligible to earn IEEE Professional Development Hours by attending these courses and participating in the chat function. Additionally, we are no longer using the points system, offering "graduation", or giving grades. The IEEE hours are taking the place of that. There are some important things for you to know about earning the hours. The most important ones are that you need to attend these courses live, you need to attend a minimum of two of them per semester, you need to fill out a course evaluation form within 2 weeks of the end of the class, you need to attend 4 out of the 5 classes per course, and you need to participate in the chat function every day you attend. Please click on the link at the top of this page that says "How do I earn IEEE professional development hours" to read all of these important details and more.

@Jacob -- do you know of any formalized process for detailed design development that would be parallel to architectural design process and methods (such as SEI's ATAM, ARID, etc.)?  There seem to be these well-defined processes or methods for developing architectures, but not comparably detailed, documented, and formalized methods for detailed design. I find that the SWEBOK has only a cursory discussion of methodologies for detailed design. (I haven't yet got the book they reference -- 4* -- however.)  Any suggestions?

Has anyone looked at Jacob's templates?

The streaming audio player will appear at the top of this web page when the show starts at 2 PM Eastern time today. When you see it, click on the play button to start the audio. Note however, that some companies block live audio streams. If when the show starts, the audio bar doesn't appear or you don't hear any audio, try refreshing your browser. If that doesn't work, try using Firefox or Google Chrome as your browser. Some users experience audio interruptions with IE. Also, make sure your flash player is updated with the current version. If that doesn't work, the class will be archived immediately following our live taping. You shouldn't experience any problems with the audio when listening on-demand.

Good morning everyone - A fix is in place so that the problem that occurred with Chrome yesterday shouldn't happen again. If anyone is curious as to what the problem was, a new version of Chrome was deployed and it broke/disabled some Flash functionality. BlogTalkRadio (the company who we partner with for the audio stream) has released a fix which forces Chrome browsers to use a different version of the audio player now (HTML5 instead of Flash).

need my info on how to design embedded software

Iron

Let's hope the sound works better today.

Looking forward to hearing about utility of UML and the like.
