AI as a Service

The product development starts soon, from the initials done over the last few weeks. An AI which has the aim of being more performant per unit cost. This is to be done by adding in “special functional units” optimized for effects that are better done by these instead of a pure neural network.

So apart from mildly funny AaaS selling jokes, this is a serious project initiative. The initial tests when available will compare the resources used to achieve a level of functional equivalence. In this regard, I am not expecting superlative leaps forward, although this would be nice, but gains in the general trend to AI for specific tasks to start.

By extending the already available sources (quite a few) with flexible licences, the building of easy to use AI with some modifications and perhaps extensions to open standards such as ONNX, and onto maybe VHDL FPGA and maybe ASIC.

Statistics and Damn Lies

I was wondering over the statistics problem I call the ABC problem. Say you have 3 walls in a circular path, of different heights, and between them are points marked A, B and C. If in any ‘turn’ the ‘climber’ attempts to scale the wall in the current clockwise or anti-clockwise direction. The chances of success are proportional to the wall height. If the climber fails to get over a wall, they reverse direction. A simple thing, but what are the chances of the climber will be found facing clockwise just before scaling or not a wall? Is it close to 0.5 as the problem is not symmetric?

More interestingly the climber will be in a very real sense captured more often in the cell with the highest pair of walls. If the cell with the lowest pair of walls is just considered as consumption of time, then what is the ratio of the containment time over the total time not in the least inescapable wall cell?

So the binomial distribution of the elimination of the ’emptiest’ when repeating this pattern as an array with co-prime ‘dice’ (if all occupancy has to be in either of the most secure cells in each ‘ring nick’), the rate depends on the number of ring nicks. The considered security majority state is the state (selected from the two most secure cell states) which more of the ring nicks are in, given none are in the least secure state of the three states.

For the ring nick array to be majority most secure more than two thirds the time is another binomial or two away. If there are more than two-thirds of the time (excluding gaping minimal occupancy cells) the most secure state majority and less than two-thirds (by unitary summation) of the middle-security cells in majority, there exists a Jaxon Modulation coding to place data on the Prisoners by reversing all their directions at once where necessary, to invert the majority into a minority rarer state with more Shannon information. Note that the pseudo-random dice and other quantifying information remains constant in bits.

Some Free Pascal Hobby Stuff

Free Pascal is a very good Turbo Pascal clone free on many systems. This includes the AROS system, which is getting better each release. It is Amiga source compatible, and as the C dev environment is up, but no IDE on AROS, the FPC IDE works a treat, and with restrictions allows cross development of source for AROS, Windows, Mac, Linux and quite a few other targets.

7/11/2018 – There is just the start of an outline. I have abstracted out some of the CLI parameter management to make it easy to make a multi-purpose CLI tool to start. This I am calling CliFly and could be expanded with simple procedures and filling out the table of recognized verbs.

9/11/2018 – There is now a fully compiling set of management words and a framework to build in some new words with more useful active utility. The ones already there could be considered foundation words, supporting the search, help and test structure. A module can be easily added by making a unit which uses “GenericProcess” for dealing with exit and getting parameters. I will extend the foundation units to supply what I find useful, such as the “CS” function idiom for string compare truth. “getParse(errName)” is also there to get parameters, and print an error from a labelled routine name if no parameters are left.

13/11/2018 – I’m thinking of making a chunk based file format for the project. Based on PNG to start, and then expand from there.

17/11/2018 – Unit U437 is for “character code pages” to Unicode translations. It will likely end up being a synthetic terminal of sorts. It does provide some format conversion functions, and so is likely to get a verb or two.

20/11/2018 – I did my own error recovering Unicode translation in the end, as the exceptions do not point to the location of the errors in the buffers. For mangled recovered files, this maybe important. There is also transparent conversion on oversized codepoints to the error character “skull and cross bones” for all my Unicode processing needs. Apart from a few render wrappers, the next thing is data compression and indexing, and of course getting down to some file wrappers.

26/11/2018 – So added a Unicode UTF8 to UGSI, so I can then design a 512 character charset, and a processing methodology for say diacritical marks. Also exceptions, file classes and the basics of the internationalization of the help text has been put together. The next thing is to put the GenericProcess unit in line with using these. As soon as that’s done, then it’s on to ADTs.

Winter is Coming!


Things are going real slow on the electronics front due to space constraints of capital. But the good news is that uncertain geometry is a good predictor of 12 fermions. The bosons will have to wait for some fancy 4 velocity put into a relativistic solution of the mass independent free space equation, so as to show how each velocity flow (up, down, electron, neutrino) interacts with mass flowing relative to it. This gives in a real sense the interaction of matter as it sees matter, and the deviation is bosonic.

Couldn’t help the topical title on this post. Weather proofing is moving slow, and is very cash restricted. As with these things almost always, having some cash help to obtain more. It’s a “bad listed” working “class” thing. They’ve got to make their paranoia pay you know.

The good news is the ides keep flowing. The dark matter telescope using atomically timed WC break door open/close sensing for example was such a laugh, and perhaps even app feasible.

Arduino Fiddling

So I’ve decided on some Arduino soldering over the next few days. Fitting a fiddly SOIC F-RAM and some other components to a prototype shield. It should be fun. Then I have to fit some more code into the 32KB, and then work out a test bed and a box. I’m sure I saw a MIDI device code for the ATMega which does the USB handling. This could be useful later, but I think it does destroy the ability to connect direct with a terminal console.

The F-RAM adds 64KB of slower but fast enough memory to the Arduino, so that more complex projects can be assembled on this prototype. A display is also planned as is some analog pots and a button. Should be fun.

Xilinx and Audio

So after the download of Vivado I can start on the musical project. A Arduino for IO, (good libraries), and a FPGA for the synth internals. It could be argued that an Arduino is not needed, but it would be fast for UI development, and super easy to interface with the LCD, pots and RFID reader.

The massive IO on the FPGA can then be used for later expansion, and the ADCs (high speed ones), can be used for audio in mixing. The Arduino ADCs are good at pots, and not really audio. In this way the Arduino becomes the LFO and controller/sequencer.

With serial UART talk between them, there is maybe enough Arduino pins to control the contrast and back light in software. An FRAM I2C 32kB for the Arduino can store local programming or UI translations. This leaves the FPGA flash for musical use without multiplexing it.

More VST ideas and RackAFX

Looking into more instrument ideas, with the new Steinberg SDK and RackAFX. This looks good so far with a graphical design interface and a bit of a curve on Getting Visual Studio up to the compiling. A design the UI and then some fill in the blanks with audio render functions. Looks like it will cut development time significantly. Not a C beginner tool, but close.

It’s likely going to be an all in one 32 bit .dll file with midi triggering the built-in oscillation and a use as a filter mode too. Hopefully some different connected processing on the left and right. I want the maximum flexibility without going beyond stereo audio, as I am daw limited. The midi control may even be quite limited, or even not supported in some daw packages. This is not too bad as the tool is FX oriented, and midi is more VSTi.

Na, scratch that, I think I’ll use an envelope follower and PLL to extract note data. So analog and simplifies the plugin. Everything without an easy default excepting the DSP will not be used. There is no reason to make anymore VSTi, and so just VST FX will be done.

Looks like everytime you use visual studio it updates a few gig, and does nothing better. But it does work. There is a need for a fast disk, and quite a few GB of main memory. There is also a need to develop structure in the design process.

The GUI is now done, and next up is the top down class layout. I’ve included enough flexibility for what I want from this FX, and have simplified the original design to reduce the number of controllers. There is now some source to read through, and perhaps some examples. So far so good. The most complex thing so far (assuming you know your way around a C compiler, is the choice of scale on the custom GUI. You can easily get distracted in the RackAFX GUI, and find the custom GUI has a different size or knob scale. It’s quite a large UI I’m working on, but with big dials and a lot of space. Forty dials to be exact and two switches.

I decided on differing processing on each stereo channel, and an interesting panning arrangement. I felt inspired by the eclipse, and so have called it Moon. An excellent WebKnobMan is good at producing dial graphics for custom knobs. The few backgrounds in RackAFX are good enough, and I have not needed gimp or photoshop. I haven’t needed any fully custom control views, and only one enum label changing on twist.

Verdict is, cheap at the price, is not idiot proof, and does need other tools if the built in knobs are not enough. I do wonder if unused resources are stripped from the .dll size. There are quite a few images in there. I did have problems using other fonts, which were selectable but did not display or make an error. Bitmaps would likely be better.

The coding is underway, with the class .h files almost in the bag, and some of the .cpp files for some process basics. A nice 4 pole filter and a waveshaper. Likely I will not bother with sample rate resetting without a reload. It’s possible, but if your changing rate often, you’re likely weird. Still debating the use of midi and vector joy controller. There is likely a user case. Then maybe After this I’ll try a main synth using PDE oscillators. It is quite addictive VST programming.

I wonder what other nice GUI features there are? There is also the fade bypass I need to do, and this maybe joined with the vector joy. And also pitch and mod wheel perhaps. Keeping this as unified control does look a good idea. Project Moon is looking good.

The Cloud Project

So far I’m up to 5 classes left to fill in

  • SignedPublicKey
  • Server
  • Keys
  • AuditInputStream
  • ScriptOutputStream

They are closely coupled in the package. The main reason for defining a new SignedPublicKey class is that the current CA system doesn’t have sufficient flexibility for the project. The situation with tunnel proxies has yet to be decided. At present the reverse proxy tunnel over a firewall ia based on overiding DNS at the firewall, to route inwards and not having the self as the IP for the host address. Proxy rights will of course be certificate based, and client to client link layer specific.

UPDATE: Server has been completed, and now the focus is on SignedPublicKey for the load/save file access restrictions. The sign8ng process also has to be worked out to allow easy use. There is also some consideration for a second layer of encryption over proxy connection links, and some decisions to be made on the server script style.

The next idea would be a client specific protocol. So instead of server addresses, there would be a client based protocol addressing string. is a server domain based address. This perhaps needs extending.
