Interested in electronics / firmware / software / embedded.
I'm building a data store. I want it to have these properties:
- No SinglePointOfFailure. If any single hard drive or other thing fails, users never even notice -- can still read and write files as always.
- "hot repair" -- a technician can fix any single failure without taking the system offline.
- "hot testing" -- I can confirm all the data is properly backed up, without risking overwriting the current "live" data with old "backup" data, and users can still read and write files as always during the test.
Surely I'm not the only person in the world that wants something like this.
A few of the people I mention this to claim "All businesses big enough to have an IT department already have something like this".
But when I ask "If such a system already really exists, where can I buy one (BuyDontBuild
)?", no one seems to know.
If such a system doesn't yet exist, perhaps I'll not only build one for me, but start selling it to other people ...
"making stuff smaller"
has programmed several EmbeddedSystem
s with little RAM, no hard drive, and anemic processors.
This leads to an interest in "making stuff smaller".
I am porting ForthLanguage
to a microcontroller with 256 Bytes (that would be 0.256 kiloBytes) of RAM.
would be a more appropriate forum to discuss it.
With little RAM, it would be nice to have a "space-optimizing compiler".

My Pascal teacher taught us to draw Nassi-Shneiderman flowcharts, and in another class I wrote a very crude prototype of piece of software to let users draw Nassi-Shneiderman flowcharts. Later I *almost* learned LabView
. This and my interest in learning new programming languages leads to an interest in
VisualLanguage VisualProgramming VisualProgrammingLanguage GraphicalProgrammingLanguage
I even became the First Editor of the Visual Wiki http://visual.wiki.taoriver.net/
I discovered HyperCard
in college, so I was already pre-primed to understand the WWW when it came out. (I suppose you can get a pretty good estimate of my age from that fact.)
I spend too much time thinking about building robots, and not enough time actually building robots.
I list pages I'm interested in on AutoPcn?
, even though it is (hopefully temporarily) disabled.
(I created SelfReplication
I enjoy building/discovering good names.
(2003-12-30: DAV created CategoryNaming
Other pages I found interesting that I should probably categorize:
(I created the page WorldPeace?
, not realizing that we already have HowToAchieveWorldPeace?
(Then I went and created the RemoteStrangulationProtocol
(I created the page DatingIsEasierThanProgramming
(I created the page ThingsYouShouldNeverDo
, but then someone else made it ever so much better)
(I created BlindAlley
(I created LearningJava
(2004-03-05 created HardwareErrata
(2003-01-14: created the page "WhatIsInformation
(2004-08-05: created "TestTheSystem
: I created LanguageOfChoice
and removed spaces from those phrases on many other pages.)
The day after I read IndexCard
on Ward's Wiki, I bought a stack of 3x5 IndexCard
I find BuckminsterFuller
(the person, or rather, the books he's written, not the WikiPage
) very inspiring.
I've built a few Platonic solids out of IndexCard
And I've started carrying around a HipTop?
as described on the
43 Folders wiki
I am happy that other people (Thanks MarkIrons?
!) fix the "space before the question mark" punctuation gaffe and my other typos.
to put "non-intuitive / common mistakes" up front. There seems to be a lot of redundancy on these pages; should I combine them and then break them back apart? Perhaps SphereTiling?

I just made that up on-the-spot for ProgrammableCalculators - I don't remember ever hearing that idea before. I extrapolated the idea of handheld devices having more and more ability. I interpolated between yesterday's refrigerator-sized ComputerNumericalControlled? metal-cutting mills, today's table-top FlutterWhumper?s, and EricDrexler's future thumb-sized Universal Assembler manufacturing plants. -- DavidCary
Re: your job hunt, please have a look at SoftwareCompaniesInBoston
. You will find an excellent list of places you can send your resumé to. It would not be a bad idea to make a similar list for other cities: Austin for example.
PS: An interesting PIM wiki written in VB: the one programmed by the amazing DonaldNoyes
our own inventor busybee: Nyswiki. If you leave your name on his homepage, he'll send you a copy.
You are welcome. Unfortunately, the EddiesWiki wiki -- which contained the entire source code for EddiesWiki -- seems to offline now. I wonder if any other wiki exist that allow people to comment on source code. Well, other than http://communitywiki.org/odd/SoftwareBazaar/HomePage . -- DavidCary
Good stuff you did on the PowerTrip
page, may I suggest adding NotInventedHere
as an example of "Behavioral aspects" section entry? I do not want to change it myself to take away the QuickDiff
credit that is yours.
One thing you scientists can help solve one of my queries. Years ago I saw lots of "solar powered" calculators, and decades ago we have watches that were "human motion powered". Do we not have enough energy to harness through these and other sources to keep a SmartPhone
running? Or is it the economics (energy still too cheap) that have prevented resurgence of such "alternate energy" solutions?

''Good question. Does this article answer your question?:
"On 'Dick Tracy' Time"
by Junko Yoshida, 2004-11-01
" A typical watch, which can run without interruption for three years, needs only 1 milliamp; a cell phone integrated with DSP and RF capabilities needs at least 150 mA."
I think this 150 mA is in the receiver, which must be constantly turned on (otherwise it wouldn't know to ring when someone called you).
3 years times (1 mA / 150 mA) is about 7 days.
My name is Marcus and I noticed that you were looking for a Hackerspace in Tulsa. I started an electronics club last year, but now we need a place to meet. So the time is nigh, that we pool together some resources and start a hackerspace!
The only internet safe way to give you my contact information (that I can think of at the moment) is facebook. You can find me there under my full name Marcus Gaskamp.
I hope to talk to you soon!
I hope to talk to you soon.
Do Tulsa electronics enthusiasts have a web site like http://geeksok.com/
I would like to set up a wiki for Tulsa electronics enthusiasts, if you don't have one already.
