Started programming at 9yo on a PDP11/70 in 1979 and just kept coding ever since.

Along the way, got to write code for some extremely cool platforms, including some Crays and Thinking Machines CM-2.

Nowadays, work is C/C++/Java/Javascript Enterprise software stack as a Sr Principle Software Eng for a major co.

peapicker··on Show HN: Bezie – Virtual MIDI controller for complex automation
Looks fascinating, I expect I'd probably use it eventually. It is about $10 too high for me for a 'buy it now, learn/use it when I get the chance' -- but it will go on my backlog for when I've mastered more of Ableton Suite.
peapicker··on Education publisher Pearson reports biggest loss in its history
The textbook industry has been publishing needless new editions and gouging students for far too long. They are only reaping the consequences of their greed.

Probably developed by the Sybase team after they bought Sybase years ago.
peapicker··on Russians Engineer a Slot Machine Cheat that Casinos Can't Fix
I actually interned at Los Alamos Natl Lab at the Center for Nonlinear Studies while Doyne was there (late 80's - dating myself - before The Prediction Company). Cool guy! He had a nifty custom piece of hardware board for cellular automata in his computer that at the time blew me away. Was a cool job... got to write code that ran on things like Cray YMP supercomputers. Had a Thinking Machines CM-1 as well... (like in Jurassic Park with the blinkenlights).

Change to roulette, chaos theory, and physicists -- using 8bit hardware in shoes -- and you get the fascinating book "The Eudaemonic Pie" by Thomas Bass. Highly recommended.
peapicker··on ‘Abusing’ the C switch statement – beauty is in the eye of the beholder
Agreed! (I had forgotten about protothreads, thanks)
peapicker··on Computer Scientists’ Trivia
Even that is inaccurate. Long is 4 bytes on 64bit windows, 8 bytes on 64bit UNIXes (all I've used) and 4 bytes on OS/400 with teraspace (an environment with 16 byte pointers)
peapicker··on Computer Scientists’ Trivia
You can't even rely on that...

long --> 4 bytes in 32 bit builds everywhere I've used.

long --> 4 bytes in 64 bit builds on windows and OS/400, 8 bytes in almost all 64 bit builds on UNIXs that I've used (HPUX,Solaris,Linux,AIX).

peapicker··on ‘Abusing’ the C switch statement – beauty is in the eye of the beholder
My favorite abuse of switch statements in C is to use them for co-routines in C...

peapicker··on 9M American men in prime working age can’t find jobs. I’m one of them
Lots of people ask, here and on other forums, things like: "Should I get/finish a CS(or other technical) degree? what's the point?"

If nothing else, it give you credentials to help avoid this sort of situation in the field you wish to work in.

Not many employers look for humanities majors to run their IT when there are many other applicants with credentials.

peapicker··on So you think you know C?
IBMi (OS/400) sizeof long is also 4 by default.

Not really "64 bit" tho-on IBMi pointers are 16 bytes with teraspace enabled.

The curse of the Otaku is spreading....
peapicker··on Sony a6000 Thinks It’s 12/31/69!
A C language time_t of zero is midnight, jan 1, 1970, in timezone with an offset to gmt of zero. You live in a timezone with GMT-5 (eastern US) which applied to time zero after transfer to your mac is 7pm Dec 31 1969 as a display time.
peapicker··on This high school class builds an entire house every year
My Junior High in the early 1980s had a class like this as well. These sorts of classes are more common than some think...
peapicker··on Clifford Attractors
I spent some time rendering these sorts of attractors back between 1995 and 2004, influenced by Pickover and Sprott...

Pardon me for not updating the site to modern standards, the html is very late 90s.

peapicker··on Android Audio Latency
Your MPD8 should work with an iPad/iPhone with the camera connector if you attach a powered USB hub to the camera connector first, and then attach the keyboard to the USB hub... I've done that to get my Novation Impulse to work with my iPhone.
peapicker··on Apple's iTunes Is Alienating Its Most Music-Obsessed Users
Full support for airplay from the app (not rerouting the whole OSX sound output to airplay like the Amazon Music App requires)
peapicker··on Prices for starter homes are crowding out millennials
Pretty sure this is because many people, with the economic instability of the last five years, are deciding not to by the big McMansions anymore and don't want to take care of them... unfortunately, this means that those with more money that millennials also want the same "starter" houses. The real problem: too many builders built big-ass houses no one wants to pay for and take care of anymore.
peapicker··on How tinkerers brought PID temp control to espresso machines
I've had cheap (~$100) burr grinders and still got too much dust in my ground for a proper-tasting espresso. Bought a Nuova Simonelli MCF (back when they were $350 instead of $600) and the commercial-level burrs and worm-gear infinite grind adjustment made my espresso incredibly better. Details on features of a grinder like this:

peapicker··on How tinkerers brought PID temp control to espresso machines
Super cool! I'm tempted to up my Silvia's game (I've a v2 from ~2003), but the lack of iOS app has me less likely to go there -- although I know you're just getting off the ground and things take time. Nice work all around!
peapicker··on Show HN: Download any song without knowing its name
Unless you are into Bassnectar and the like... ;)
peapicker··on Show HN: Muki, music streaming from MIDI and chiptunes
Contrary to the intro, Seems to me that I recall most old games using MOD and other tracker formats instead of MIDI.... but the point is that it was sequenced samples, I suppose.
peapicker··on California Has a Plan to End the Auto Industry as We Know It
If you look at GDP per person in the population, California is only 14th in the US ($58K per person -- Delaware at #1 is $112.K per person GDP), so they have room to more efficiently make that GDP per person than they do. Delaware does have a higher CO2 emission rate per capita, tho (nearly 50% more than California)
peapicker··on The most popular APIs and tech at college hackathons
I was surprised Android wasn't a higher percentage... Look at it this way:

78% of the current smartphone market is Android, 18% is iOS. [1] (4.3:1 in favor of Android)

According to the article, 38% of hackathon devs are interested in Android dev, and 22% are interested in iOS Dev. (1.72:1 in favor of Android)

From this perspective, desire to develop for iOS is MUCH higher than market representation, meaning that (as I read the numbers) comparatively, Android appears to be the weaker choice -- and that amongst hackathon developers, iOS is far over-represented compared to the market as a whole, as I assume most at these events use their own devices.

peapicker··on What to know about encodings and character sets
From the article: "Overall, Unicode is yet another encoding scheme."

It is more than that - for instance, it includes algorithms as well... for instance, dealing with RTL languages with ordering and shaping rules (i.e. Arabic), how to know what to do when RTL languages are mixed with LTR (is that '.' at the end of '123' a decimal point, or a period? (determines if it goes to the right or the left or the sequence)) and how to know when data is equivalent despite being normalized or not, etc...

peapicker··on China calls on US to follow its lead in eradicating ivory trade
So my 1920's piano would then be illegal to sell, just because it has ivory on the keys?
peapicker··on The Twisted History of Your Favorite Board Game
Since the title said 'favorite' I was hoping this would be about Cities and Knights of Catan... but in my heart of hearts, I knew it would be the despised Monopoly.
peapicker··on Show HN: Viktor NV-1 Synthesizer
This is very nice, has some great sounds!
peapicker··on Do we really still need a 32-bit JVM?
Another consideration is that many shops have in place C and C++ code that is 32 bit, which hosts JVMs and uses JNI to talk to them.
peapicker··on An Analysis of Nespresso
The "fines" that result are so few that I wonder if most of the pod contents are basically 'instant coffee' espresso powder.
