Sneaky nasty Windoze 10

Posted in Uncategorized on September 15, 2015 by asteriondaedalus

Watch out!  I have CHROME installed on Windoze 10. I have CHROME set as my default browser.  Occasionally webpages pop up and tell me my browser is out of date.  Thing is the webpages are telling me they are detecting IE and not CHROME.

Might be a problem with the web page yes?

But it is IEEE webpage telling me it sees IE on my machine and not CHROME which is what I am running to look a the IEEE web page.  What sneaky nasty game are MICROSOFT playing?

Small steps

So, finished an online 8 week course I was interested in doing.  MOOC no less.  Not sure about them as my feeling was you don’t get much connectivity with teaching end and it would appear that MOOC are not hitting their target audiences.

I am going to do one on first order logic, for my stuff I play with at work (I am moving into formal languages).  Another will be on AI planning (for fun at home).  In any event, some time to kill so I wired up a breakout to mount an ESP8266 on a breadboard to try out nodemcu, and voila!

Hello world from nodemcu

Hello world from nodemcu

Now my wife wants a few things around the house, like burglar detection down the alleyway etc.  So I have a batch of IR detectors and the nodemcu can email detections no less.  The alternative is to SMS via a cheap GPRS module:

Tini!

Tini!

Now this was under $10 and the module is the size of a phone MicroSIM card.  TBD

Even better, OpenHAB with MQTT addin, OpenSprinkler addin … there is no end to this madness.

Not to mention a python library for pumping Aus weather to MQTT.

Book not out of date, neither was software but do update software to version not called out in book

What a long title.

I bought a book on Processing 2 for Android.

I downloaded Processing 2.

It had suffered a minor setback as they had, apparently, lifted out the Android mode – rendering the book worthless.

I pinged the publisher for money back.

They pinged me with response author said book is not out of date but I should download Processing 3.

To wit I replied with the following:

RE: Money back please Order #xxxxxxx

To: xxxxxxxx Support

Cheers,

So, book is based on Processing 2.  Processing 2 no longer downloads with Android Mode (which was the root cause of problem) but book is “not out of date”.  Even though current Processing 2 version does not work as detailed in book.
But downloading Processing 3, which will make Processing 2 out of date, will have Android mode but not make the book based on Processing 2 out of date.
Gotya.  When you put it like that it all makes sense.
Have you ever heard the notion that the simplest lies are the best ones?
It actually looks like a minor incremental of the Processing software removed the Android mode post book release.
Look, I work in Defense.  We often have to lock stuff in “time capsule” for up to a decade to provided support.
As much for yourselves as a “victim” here, how about a policy that, authors need to “freeze” any supporting software (within reason) as kindness to people buying their books.
Space on github, source forge etc. is there for the taking.
In the meantime I will try the pesky Processing 3 that isn’t the Processing 2 that will be out of date but wasn’t why the book was.  (Let me know if you think I have the hang of it 😉

And they’re OFF!!!!!

This is a famous photograph. More or less invention of moving pictures that we all know and love. Look at it, scroll your mouse wheel up and down quickly, just a quarter of a turn to go back in history two turns of a century.

So, FINALLY got the call from the nephew.

Project has changed somewhat.

The original thought was a touch screen monitor based kiosk for students to pick up daily messages held in a csv file somewhere on the network.

The change was to use Android tablets (must grate as me nephew is a true blue Appleyte), and to parse data out of a html dump!

Parse data out of a html dump?

Turns out the skool system can turn out a webpage report (so I am a little dim as to why they need do much more that set up a browser looking at that webpage).  Anyway, my nephew is excited to be working with his uncle (and I needed an excuse to by four odroid-w, the wife you know).

So, his teacher pointed him at BeautifulSoup which is a python library for sucking data out of html files.

Beautiful is right.

Here is our first experiments (the whoopses excluded):

Untitled

Basically if there are tables within the html the code can pick them out.  He had the idea himself of just reusing the html for the table in our file – brilliant.  So, only problem is other data is buried in nondescript <p> tags.

Will need to sleep on that.

Back at it

So, first thing I did was to open up one of the Verilog prototyping text I got to start training up on the xilinx tools. Half a day doodling with the tool, changing the designs, synthesizing, simulating … most stimulating.  I got myself a copy of “FPGA Prototyping by Verilog Examples” by Pong P. Chu.  So, with the latest ISE Design suite installed one can design and verify without having to even heat up the soldering board.  I’ve also got the Altera toolset installed so I will try running the examples in there as well to get a feel for the difference between the two tools.

Also managed a copy of the “Blue Book” – the gospel of HDL design.  And another recommended text is on the way.

Cobwebs thus slowly dusted off.

Today, I went back onto the modifying of the firmata code to work with s4a python and bluetooth as a prelude to integrating with POSH – then onto SPADE.

I opted to knock up two modules: 1) for the Romeo on the indoor rover

; and 2) for the MEGA1280 I use for experimenting.

I have experimented with the SNAP modules in the MEGA board and you’ll note I also got a XBee format Bluetooth module to allow me to drive the board with Bluetooth commands as well.

As luck would have it …

A pal upgraded his Android game pad and gave me his superceded toy.

Turns out it’s a JXD S5110.  No bluetooth but has wifi and gamepad buttons so a wild addition as it can act as a remote console/controller talking to either the Gumstx Killer or any of the Android phones I am using as roving camera/brains.

Although, I guess the temptation will also be to use it for control of the AR-Drone (trawling Internet to find out to get access to the buttons).
