From Utah, catching up...

Iron

Catching up here as well.

Iron

Hello to archive learning

Looking forward to the second semester and next weeks class

Thanks alex thanks gary

Picking up the last lecture

@Gary - and more rhetorical questions today...

Iron

@Gary - what's up with the picture on slide 3??? (does not look like there is much "planning" going on)

Iron

@Alex - h/w, s/w and currently standards focus

Iron

Great that we have access to the recorded sessions!

Iron

Missed a lecture again...

Iron

Hi, Alex, Gary, all, a belated HI!

Iron

@Gary - Thank you very much for your week of impartations.  We have enjoyed it.

 

@Alex - Thank you to for you hard work too.  We will miss you and remember you.  We wish the best to you in your new endeavor.  Please extend our appreciation to Digikey for making this possible.

Iron

@rhall007 – I don't know why it has to be that way, but it seems to happen too often.  Where is the reward for your contribution?  In so many ways, what happened to you is just so very wrong.

Iron

@jl - My condolences on your job loss...  I feel strongly for you.

Iron

@Gary – Working myself out of a job: It has happened, and it does not feel good at all.

Iron

@Gary - Having "constants" in a R/W register seems like a good idea, but I can't think of a time that I ever had that much foresight.  I'm not clairvoyant, but sometimes I wish I were.

Iron

@Gary - My first printer was the original inkjet.  Bought it in 1988.

Iron

@Alex - Planning ahead is part of my professional and personal life, but sometimes pressures and external influences prohibit planning.  Bummer.  That's when I don't feel I have control.

Iron

@Gary - No retirement or savings for kids at this time.  All kids grown and gone.  They have their own retirement plans.

Iron

@Gary - Retirement plan: Yes.

Iron

Welcome back this for this final session Gary.

Iron

Hey folks.  Sorry to be so late, but I needed to spend the afternoon at one of our local TV stations.  After that, it was taking care of domestic matters and getting the day's calendar cleared of so I could have some peace to focus on our forum.  But, at least things are archived so that I can avail myself of this added knowledge.  So, let's get down to it.

Iron

My green was fine!

Systems Engineering Manager

Iron

Gary, thanks for the interesting week. You presented a lot of ideas to help with new project challenges and reflection on past experiences that were successful, nor not and why.

Iron

Alex, good luck and best wishes in your new assignment.

Thank you, Dan.

Iron

Just being a computer hobbiest was being a problem solver in h/w, s/w and system integration just to get something to work.

Iron

Alex's comment about not knowing what's under the hood resonates with my feeling. I learned at the time when a single person could understand the relatively simple h/w, OS or monitor and the applications. That ability is going away with current systems.

Iron

Very nice training, Thanks

Iron

Thanks and happy weekend!  Excellent series.

Iron

Gary Jet == fast it's a marketing and perception thing. :)

@EdB_Vt - I don't know how/why they carried the *Jet to LaserJet. It has definitely been part of HP's printer and tools naming. InkJet, ThinkJet, QuietJet, OfficeJet, JetSend, JetAdmin. Several years ago a competitor tried to sell a PhaserJet printer but HP lawyers manage to squash that.

Iron

Thanks to all - the interaction on this class has been enjoyable and useful. (Besides the HP war stories are always fun :)

@jl - Agreed - all new programmers/engineers should have to do a stint supporting legacy products to learn how to avoid pitfalls.

Awesome; glad to contribute!

Going to have to come back and review archives; the end of the middle-school year is unfolding around me, so early-dismissal taxi-duty beckons. Catch you guys on the next turn of the wheel, eh?

Thanks and good luck, Gary, Alex!

Platinum

planning for future comes from experience. this experience comes from maintaining existing systems. one learns quickly the good practices and that saves time, and learns that just a little better design that allowed for future changes saves a ton of time, effort and money

Iron

@flaredOne - "attach spare pins to a trace to a through-hole." I like that. I've added it to my best practices list.

Iron

Goal is to maximize the benefit of good guesses and minimize the impact of poor ones.

In guessing the future, if you HAVE an 8-bit register and are only using 4 bits, you CAN kinda "predict" those spare bits will come in handy SOMEtime. So attach pads/throughholes for rework ECOs (avoid someone having to solder directly to chip leads, at the very least). Or a 10x4 PLA; same thing.

Platinum

Gary - as long as your average is better than 50% you are making forward progress. :)

@Alex - what was the series you are going to be hosting

Iron

Several have commented about not being able to guess the future. No, we cannot guess everything perfectly. But how many times have you guessed right? Though all my future guesses have not been correct, many of them were correct.

Iron

Heh -- you guys got the degree FIRST, THEN started your careers. I did it the other way around, so when I got into those college courses (relatively recently; STARTING though with 1.5 years at MIT did help), I had a MUCH better feel for "good point" versus "yeah, right" re stuff some instructors were pushing.

Platinum

@jl - Good observation. My planning ahead doesn't mean implementing the future now, but leaving room so that I can implement it later. We did not hook all 8 of those positions to I/O pins, just the 5. But when we needed the 6th, then we added in the register where there was space reserved.

Iron

@flared0ne Agreed - can't beat the school of hard knocks.

@TonyH - Iowas State '84 I got that degree - matches your description.

Current college courses DO cover a large amount of this stuff -- unfortunately, it isn't the kind of thing that makes a lot of sense until you've had some time "in harness" and seen a few of the many ways that people can do design WRONG!

Platinum

Good luck with your new assignment Alex. Hope to see you back in the future. Which series are you hosting?

Iron

best wishes on your new venture Alex.....

Iron

Thanks Alex - won't be the same without out you :)

Best of Luck Alex.

Thank you for a great week fo lectures.

Iron

Thanks for your lectures. Very good principles

 

Iron

Bye Alex, good luck on your new venture.  You hosted a lot of good topics.  Thank-you.

Thank you for all the best practices!

IT should be part of engineering school teaching!

Iron

University of Illinois had Computer Engineering Degree in the late 70's.  Basically a Elect Eng. Degree with software and computer architecure courses.  My graduating class had 33 students in it for that degree.  

Iron

Thanks, guys, it's been surprisingly real.

Platinum

Thanks Alex and good luck with new assignment

Iron

thanks Gary, thanks to Alex and DigiKey

Iron

Good Luck Alex in your next endeavor

Thanks Gary and Alex for an interesting series of presentations.

Iron

Right= T-shooting with desigh experoence gives you in the future good position as a good verifier of ANt documentation...and of cors your responsibility to new generation is to brcome TEACHERs as YOU ARE guys. Congrat for exelent job

 

Grary: Thanks for sharing your knowledge and experince

Iron

Embedded System Design had an article on a college cirrucilum for embedded software engineer.

Blogger

what is the course starting June 4

Iron

TaBLET, taBLET, taBLET!!

Platinum

The pendulum swings -- USED to be just "EE", now there's CS and EE. That is soon to be merging again. At this point, with totally configurable programmable DRAM-type processor cores, an ASIC where you can program up to four cores, NOW the line between Hard- and Software is fuzzier than ever.

Platinum

Agree hw understanding should be required for CS degree.

I'll agree with the Engineering being taught how to approach problems and how to consider aspects that don't appear to apply at first view.

So hardware is in the physical (your brain) and software is the metaphysical (your thought). You can disect the physical, but...

 

Iron

Gary,  Great week of lectures.  I think the most critial point is to use standards. This allows easy collaboration with teams, better defined projects and ability to re-use code and do it right the first time.  Thanks for the great points.

Iron

Alex, you mention agile.  This is just a production methodology.  It does not address design.

Blogger

GREAT OVERALL LECTURES AND COURSE. VERY LEARNED INSTRUCTORS...

THANKS..

Audio must be done.  I can catch in archives.  Thanks Gary if I have any questions I will email,

Iron

Not true Gary - Got a Computer Engineering degree in 1984

I had a similar discussion with an Alumni rep about CS majors don't know how a computer works...

Iron

the scary thing is that hardware design is becoming more like software design.

Blogger

A comprehensive survey of design-planning tools might be a valuable resource, if not a whole week of discussion. Kind of begs a bit different level of interaction, though -- not clear when "Chat" may be part of a bottleneck...

Platinum

thinking "outside the box" while staying focused seems to help me resolve, and antisipate problems.

Thanks to you Gary and Alex for the material presented, and to you all for your interesting comments.

Iron

Check out some current commentary about Microsoft changing over to support Open Source software -- they're seeming to lean toward some very useful design-planning tools.

Platinum

Those "phylosophical pronciples" are so IMPOETANR.

Believe, it has so good "leadership" in other desognings, e.g. in larger Process Control Projects!  THANKS!!!

Thanks Gary and Alex.

 

Iron

Software can be as precise but there is no "standardized" approach for "IC or other modules".

There is an effort to create a Software PE due to safety critcal aspects of SW.

Thanks Alex for this great series of lectures.

Had trouble. here now

Iron

@flaredONe - we will certainly not focus on you  :^)

Iron

Thanks Gary for a great presentation.

Gary Thank you very much for the courses , very useful information

Iron

Thanks also to the folks who chimmed in and shared some good ideas.

Iron

Also, thanks to Alex, and Digikey for sponsoring this series, very worthwhile

Iron

Great presentation! Good discussion n the 7 principles.

thanks Gary, great presentation. Hope you will be back for future sessions

Iron

@Gary - Thanks, you have given this old hand an interesting week of information and idea support.

Iron

great presentation, one of the best

Iron

Auto_Tink - yeah when you are leaving and they are trying to figure out how to relapce you it finally shows them what you have been doing... 

Iron

Don't focus on ME, here (unless that's foreshadowing a tablet somehow [hope, hope!])...

Platinum

Thx. Gary and Alex

Iron

Thank you Gary for your the great presentations

Iron

I hope everyone has a great weekend+

Good idea flaredOne

Iron

Great week!   Thank you everyone!!   :)

Thank you for sharing your experiences Gary. Great presentation, Also thank you Alex and Digikey

Iron

Thanks for this great series

Iron

Thanks for the presentations!

thank you Gary,

Iron

Thank you Gary. This was a great series.

Iron

Thank you Gary. We apreciate the knowledge

Iron

In my first job out of college I was "disruptive" since I produced more than others in group. I was transfered to a different group.  That was a good thing for me.

Iron

It actually helps if you physically WEAR a different hat -- makes it visible that you're working on something specific.

Platinum

I agree flaredOne. I have worked at several startups and wearing many hats is something that is valued to some degree. But sometimes (not always) they dont realize how much you are covering till you are gone.

Iron
cheap is cheap and most of the time bad
Iron

cheaper may not apply to custom-made products, am I not right?

Iron

Yes big believer in helping people learn to help themselves and get backups for my tasks

Iron

FOLLOWING THESE PRINCIPLES, I HAVE WORKED MYSELF OUT OF SEVERAL POSITIONS BY PRODUCING MORE THAN OLDER EMPLOYEES.

I worked hard to bring a product line to the point where it was 2-3 yrs ahead of the competition. Management thought it best to lay me off to save money since we were so far ahead.

Iron

yes...have worked myself out of a job because of these and other practices...was fired because the company no longer needed me

Iron

If you are in a smaller shop, the ability to "wear many hats" makes you valuable because you cover for what would otherwise take more people.

Platinum

The R/W hardware-based constants sounds very similar to the adjustments for monotonic linearity for ADCs and DACs. Yes, absolutely -- hardware "tweakable" variables are hugely useful.

Platinum

Just checking -- you familiar with programmable logic devices which are like DRAM?? Every time you power them up, you have to load them with their configuration, their logic tables, etc. I mentioned this yesterday, having encountered a situation where there was a huge multi-function ASIC AND an adjunct "boot PROM". Point: make the load-space selectable, so you can access variations and (perhaps) diagnostic versions of the ASIC without having to change out any hardware.

Platinum

Make SW controlled timing this way but have some issues with highly constrained embedded systems.

When starting design leave enough time window between your normal functions and to service your critical interrupts, so that you don't miss the timing of interrupts.

Software patches and fixes and work around will eat into that time window !!

 

Iron

every single time!!!!

Iron

So tell us where the "jet" is in a LaserJet. Certainly inkjet printers have jets that shoot ink.

Iron

have you seen Lean Design?  there was a post on LinkedIn in the System & Product Design Engineering Group on this that echos much of what you say. 

Blogger

Try to do it all the time. I will use symbolic constants to avoid recoding because the design needed to move signals.

When designing industrial control panels, it is standard practice to have 25% open panel space, as well as margin for power supplies.

Iron

"FlaredOne" -- Bingo !!

Iron

Planning ahead is essential as a form of a business plan. Busines plans are always needed for financial consolidation with financial institutions

Iron

If you HAVE the option to select "slightly larger than actually needed Right Now", go for it. Excess pins, among other things, simplify layouts (more physical-path choices). Key point: if you HAVE spare pins, attach a trace which runs off to a labeled through-hole (someplace you CAN attach a jumper lead). Priceless.

Platinum

planning is essential for most of us especially when it is a start up environment. Too easy to get off path

Iron

you need to plan all ahead. hardware is very important because is not like in s/w – rebuild, patch, etc

Iron

You are lucky if your job function has a predictable path. Or a product line with "logical" next step developments. Some places that works, many it doesn't.

Platinum

Hello....planning ahead is a business plan

HP lost their way once Bill and Dave passed.

what you say is right.  on the other hand, in the software world you have "agile" which ignores design.

Blogger

Re finance, savings question (which I missed -- just got back): I recently finished up my BsEE (non-traditional, after "a few years" working -- was amused by a SIGNIFICANT amount of time in an engineering-specific class spent on investment counseling, "The Power of compound Interest", etc. Have started some trusts for the boys.

Platinum

We always put on paper our planning aheads. We do try to project realisticly, but with this economy, future always surprises you!

Iron

Slide 6 is unspoken rule but when pressed management will say do it right without any changes to the schedule.

what I am hearing from Gary's presentation...planning ahead is not necassarilly putting in future functionality...but rather leaving room for expansion in registers usage, memory, type definitions, etc

Iron

Alex, you must be using an old version of the software

Blogger

and of course you never get the chance to improve it.

Iron

CONSTANTLY................................

so why is HP where it is today?

Blogger

Thinking ahead helps to write software that can be reused.

Iron

Honestly, my planning ahead is mostly in my head.  Concrete steps for strategic planning don't get enough attention due to daily pressure items.

Planning ahead is always a good idea but the benefit is only as good as your ability to predict the future.  If yoiur guess is correct planning ahead pays off.  If you are wrong there's probably no gain.

Iron

for software it makes more sense in this situation.  hardware should be designed to get the maximum price/performance out of the silicom

Blogger

Timne pressure often makes it difficult.

Iron

I'm reworking existing code to allow for simple extensions without fundamental code changes. This is planning for future support.

Yes. and Lots of reused.

Iron

Yes - plan ahead/anticipate

Iron

You HAVE to put your foot down. Otherwise it's YOUR credibility which will suffer IN THE FUTURE.

Platinum

Planning ahead has always saved me on spin-off products

Iron

Plan ahead: want to, but time pressures often prevent doing that to the extent we want to.

 

Iron

I covertly plan ahead..............

Planning ahead always pays off!

Iron

Tell that to the bean counters (only maximizing the current quarter)

Or the other joke is what is the easiest way to make a million dollars, start with $10 Million

Great Friday and for some of us a three day weekend.

hello everyone...another great friday and looking forward to another great presentation

@flared0ne

I looked at the Leap product and it looks interesting.  I thought about signing up as a developer but I don't have the time to take on anything additional right now.  I'm getting one of the devices to try out, but having to wait until the end of the year or longer is a bit of a "bummer."

Iron

good afternoon from cloudy and dreary NH

Hi everione from sunny Pittsburgh

Iron

Rainy and 48°F here in Boise.

Iron

good morning from rainy San Diego.

Yes, there will be more in the next 180 days.

Hi everyone.  Another Friday and another section completed.  I see Alex has added one more course to the list.  I wonder if there will be more to follow on this track or if Digi-Key or someone else will carry this forward to the second 180 days of the year.

Iron

Good Morning. Silicon Valley CA .Partly cloudy and cold 54°F.

Howdy folks!    :)

Breaking it up into individual paragraphs seems to be working.

Now for some "hurry-up-and-wait" noshing. And a bit of focused job board browsing, etc...

Platinum

Anyone check out that LEAP product re gestural input device with 0.01mm precision in 3D space? There is an opportunity to MAYBE sign up as a developer and get a free device and access to the SDK. Could be a "get in on the ground floor" opportunity. Just my opinion, but I predict this device is going to raise the standard of "Elegant" in graphical user interfaces and virtual functionality -- the device is reasonably priced for market penetration, could influence a "bump" in heads-up display glasses, and might actually 'rescue' a bit of the market for 3-D monitors.

Platinum

Let's see: anticipating the "usual" questions -- I am predominantly hardware: project, proto, product; with more than enough software to make the hardware walk, talk, sing, dance, see, hear, communicate, be produced and tested with embedded diagnostics -- AND (generally) to be profitable and supportable. Currently seeking gainful employment AND contemplating and researching a wide range of possibly lucrative projects. Last time I checked, it's in the mid 80s outside (again), on its way to the mid 90s.

Platinum

Good afternoon to all. It appears Chat is STILL losing posts (THIS is my third try for THIS content) so I'm covering my bases: selecting and copying all this text, then pasting it in a text buffer off to one side, just in case it gets lost AGAIN.

Platinum

Dropping posts. (test, test, test).

Platinum

Was just reading through some stuff about Microsoft STARTING to "embrace" open-source. I was struck by just how much of the conversation was about the evolving semi-formal knowledge base which revolves around Best Practices for "collaborating" on making use of knowledge bases, i.e., those misc shared libraries of functions, etc which are arguably among THE most useful contents in most software developers' "tool kits".

 

Gotta love the self-referential stuff, AND the synchronicity of stumbling over that while contemplating "Best Practices" and "Principles" and how best to implement those in a larger-than-just-one-person design environment.
