Links to projects

A lot of material on various subjects is contained in various project files, nearly all of which conform to the file naming convention, 'define_$PROJECT.html'. Other info may still be in $doc, the cache of info before the project-related emphasis took over.
eg: C,C++,Cplus should all route a reader to define_cplus.html which might, in turn, link to info pockets on makefiles, books, source tree areas, etc.

Context markers, programming languages, hardware type

This particular glossary is a consolidation point for terms arriving from many other files (contexts), such as terms found in javascript. And sometimes it's useful to know the context under which a definition was found. And sometimes a term has a similar meaning in several contexts. Many entries here predate the effort to attach context info but, where context info is available, it'll be placed immediately after the <dd> inside parentheses. Note too that commas surround both ends of each term, eg:

The following lists the context names found in this document.

Action Memo is meant for quick notes that you can take action on now or later.
To start an Action Memo, just hover your S Pen over the screen and press the button.
The Air Command fan will appear. Just tap on the first option, Action Memo.

You can now write whatever you want in the memo such as a phone number, email address,
or street address. Just tap on the "Link To Action" button at the top and it will highlight
what you wrote. You will then be given an opportunity to make a phone call,
add a new contact, send a text, send an email, search the Web, open Maps, or add items
to a todo list. Just choose the appropriate action. You can even save your Action Memos
to use later by tapping on the checkmark at the top right. To open previously saved
Action Memos, just open the Action Memo app from your app drawer.

AirDroid is completely free; it doesn’t even contain ads. It functions as a web server,
allowing your Android device and your computer to communicate over the network.

AirDroid is available for free from the Android Market (saw screen image of phone going

It supports Android 2.1 and
later. Android 4.0 isn’t as well supported at the moment, but AirDroid should update
with improved support soon. (160615)

1. Launch AirDroid on cell phone.
2. Tap Start on cell phone to start the AirDroid _SERVER_
3. Note that the cell phone screen contains (the phone's) IP address and
   it's inviting you to connect on to that address on port 8888.
3. plug the IP address into your web browser’s address bar, eg:    note the colon before the 8's
   NOTE !!! I'll write 'PC' to identify the machine which is connecting
   to the phone. Except for screen size problems, I think it could be
   another phone, a linux box etc.
4. type in 'password'. Use the code from your phone's screen to log in.

arduino versions
(,webCtl,) The Arduino releases contain the IDE, drivers, libraries, and examples and each release is given a distinct 'version number'. ("Release number" is more appropriate than "version number" since the functionality only has minor enhancements, release to release).

  • 0018: This number identified arduino's release years ago. It could be viewed as "0.018", implying it's a test release pre-dating the 1st "1.0" real release.
  • 0021:
  • 0023: This release was current in 2011
  • 1.0: current as of May 2012
  • 1.0+: a program claiming compatibility with "1.0+" means it works with "1.0" and expects to work with all following releases.
  • 1.03: downloaded to Castor and Lenovo Jan '13.

// fm then search for title: Wireless Client Association A wireless client's association to a selected access point is actually the second step in a two-step process. First, authentication and then association must occur before an 802.11 client can pass traffic through the access point to another host on the network. Client authentication in this initial process is not the same as network authentication (entering username and password to get access to the network). Client authentication is simply the first step (followed by association) between the wireless client and access point, and it establishes communication. The 802.11 standard specifies only two different methods of authentication: open authentication and shared key authentication. - Open authentication is simply the exchange of four "hello" type packets with no client or access point verification, to allow ease of connectivity. - Shared key authentication uses a statically defined WEP key, known between the client and access point, for verification. This same key might or might not be used to encrypt the actual data passing between a wireless client and an access point based on user configuration.

temperature and humidity sensor.  $5
The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor.
It uses a capacitive humidity sensor and a thermistor to measure the
surrounding air, and spits out a digital signal on the data pin
(no analog input pins needed). Its fairly simple to use, but requires
careful timing to grab data. The only real downside of this sensor is
you can only get new data from it once every 2 seconds, so when using
our library, sensor readings can be up to 2 seconds old.

Compared to the DHT22, this sensor is less precise, less accurate and
works in a smaller range of temperature/humidity, but its smaller and
less expensive

Comes with a 4.7K or 10K resistor, which you will want to use as a
pullup from the data pin to VCC.

Digital Certificate
A Digital Certificate typically contains the:
  • Owner's public key Owner's name
  • Expiration date of the public key
  • Name of the issuer (the CA that issued the Digital Certificate)
  • Serial number of the Digital Certificate
  • Digital signatureof the issuer
The most widely accepted format for Digital Certificates is defined by the CCITT X.509 international standard; thus certificates can be read or written by any application complying with X.509. The certificate is signed using the certificate issuer’s (CA) private key. Everybody knows the certificate issuer’s public key. Certificates are a standard way of binding a public key to a name. A digital signature scheme typically consists of three algorithms:
  • A key generation algorithm that generates key pairs. The algorithm outputs the private key and a corresponding public key.
  • A signing algorithm which, given a message and a private key, produces a signature.
  • A signature verifying algorithm which given a message, public key and a signature, either accepts or rejects the message's claim to authenticity.

"a set of computers" NIS Network Information Service. (was "Yellow Pages", Sun Micro.) A NIS/YP system maintains and distributes a central directory of user and group information, hostnames, e-mail aliases and other text-based tables of information in a computer network. For example, in a common UNIX environment, the list of users for identification is placed in /etc/passwd, and secret authentication hashes in /etc/shadow. NIS adds another “global” user list which is used for identifying users on any client of the NIS domain. Administrators have the ability to configure NIS to serve password data to outside processes to authenticate users using various versions of the Unix crypt(3) hash algorithms. However in such cases, any NIS client can retrieve the entire password database for offline inspection. Kerberos was designed to handle authentication in a more secure manner. DNS PDC type (windows). Primary Domain Controller. pre Win2000 The "User Manager for Domains" is a utility for maintaining user/group information. It uses the domain security database on the primary controller. The PDC has the master copy of the user accounts database which it can access and modify. Newer MS scheme is Active Directory: An AD domain controller authenticates and authorizes all users and computers in a Windows domain type network—assigning and enforcing security policies for all computers and installing or updating software. For example, when a user logs into a computer that is part of a Windows domain, Active Directory checks the submitted password and determines whether the user is a system administrator or normal user. Active Directory makes use of Lightweight Directory Access Protocol (LDAP) versions 2 and 3, Microsoft's version of Kerberos, and DNS.

flyback diode
diode needed to suppress the induction-caused spike which can damage the parent circuit. This polarity of this spike is the opposite of what the circuit used to create the magnetic field. Suddenly stopping support for that field, as happens when a switch turns off, allows the field to collapse. A typical such diode is from the 1N4000 series such as the 1N4001 (smallest of the family). 1N4004 the largest.

    Sometimes synonym for "router" but a

    2 dissimilar networks. The gateway is expected to translate between

    However, common parlance treats gateway as a device on YOUR network
    which feeds thru to another network (presumably w/ a different
    network number), whether it's of the same type or not.
definition in sysconfig/network or sysconfig/devices/ifcfg-eth0 etc. gives an IP adr for packets leaving the associated network. The device having that IP will also have 1 or more other IPs (for its other network(s))

Google Drive, host web pages
Host webpages with Google Drive, an expansion of:

With Drive, you can make web resources, like HTML, CSS, and Javascript files, viewable as a website. (Google Drive does not support web resources that make use of server-side scripting languages like PHP. duh).

(fgh: this was disappointing: It does display an html file as a web page but the source file isn't then editable (b/c it's not a Google Doc)! The site must be totally public. It's labor intensive and it isn't obvious how to reduce the labor w/ scripting. There must be "an API for that..?.". Even if a scripting-based method is found, there's a problem in translating local link values to cloud addresses.)

Here's how they said to do this: (and my notes)
  • Create a new folder in Drive and share it as "Public on the web."
    • 'Create'; 'Folder'; name it;
    • click share icon (silhouette of a person)
    • "Who has access": click "change", select "Public on the web."
    • click 'Done', at bottom
    • FWIW, it made link:
  • Upload your HTML, Javascript, and CSS files to this folder.
    • (the "upload settings" for gdrv were important for getting non-web uploads to become editable on gdrv. Not wanting these uploads to get converted to gDoc format, I unchecked all, most importantly "convert uploaded files to Goggle Docs format")
      • in Google Drive's web UI
      • click the 'gear' icon at the right
      • click "upload settings"
      • uncheck "convert uploaded files to Goggle Docs format"
    • Click into the new folder
    • Clicked red box w/ up arrow ("Upload"), "Files" since I just made a new folder
    • uploaded each folder independently of 'files' (doc/, webish/)
    • clicking on .html shows its text; doesn't display as a web page
  • Open the HTML file and click Open in the bottom-right corner.
    // still see the html source...
  • Click the "Preview" button in the toolbar.
    // now it looks like a correct web page.
Share the URL from the preview window and anyone can view your web page. Eg:

libraries, arduino
Standard Libraries
The Arduino IDE comes with a set of standard libraries for commonly used functionality. These libraries support all the examples included with the IDE. Standard library functionality includes basic communication functions and support for some of the most common types of hardware like: Servo Motors and Character LCD displays. Standard Libraries are pre-installed in the "Libraries" folder of the Arduino install. If you have multiple versions of the IDE installed, each version will have its own set of libraries. For the most part, it is not a good idea to change the Standard Libraries or install your libraries in the same folder.
User Installed Libraries
There are many other libraries with useful functionality and device drivers for all sorts of hardware. These drivers are available from places like

  • Arduino Playground
  • ,
  • Github and
  • Google Code.
Adafruit provides over 100 libraries libraries supporting almost all of our Arduino compatible products. Most of our libraries are hosted on GitHub. Direct links are provided from the product description and/or tutorial pages. User installed libraries should be installed in your sketchbook libraries folder so they can be used with all versions of the IDE. This way, if a new version of the IDE is released, you don't have to re-install all your favorite libraries

USB On-The-Go, often abbreviated to USB OTG or just OTG, is a specification first
used in late 2001 that allows USB devices, such as digital audio players or
mobile phones, to act as a host, allowing other USB devices, such as USB flash drives,
digital cameras, mice or keyboards, to be attached to them. Use of USB OTG allows
those devices to switch back and forth between the roles of host and client.
For instance, a mobile phone may read from removable media as the host device, but
present itself as a USB Mass Storage Device when connected to a host computer.

In other words, USB On-The-Go introduces the concept of a device performing both
master and slave roles – whenever two USB devices are connected and one of them
is a USB On-The-Go device, they establish a communication link.
The device controlling the link is called the master or host, while the other is
called the slave or peripheral. wikipedia

proxy server
acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource available from a different server and the proxy server evaluates the request as a way to simplify and control its complexity.
if it just passes stuff along w/ minimal examination, it's called a gateway.

public key

Public-key cryptography can be used to encrypt data communicated between two parties. This can typically happen when a user logs on to any site that implements the HTTP Secure protocol. In this example let us suppose that the user logs on to his bank's homepage to do online banking.

When the user opens homepage, he receives a public key along with all the data that his web-browser displays. The public key could be used to encrypt data from the client to the server but the safe procedure is to use it in a protocol that determines a shared symmetric encryption key; messages in such protocol are ciphered with the public key and only the bank server has the private key to read them. The rest of the communication proceeds using the new (disposable) symmetric key, so when the user enters some information to the bank's page and submits the page (sends the information back to the bank) then the data the user has entered to the page will be encrypted by his web browser.

Therefore, even if someone can access the (encrypted) data that was communicated from the user to, such eavesdropper cannot read or decipher it.

This mechanism is only safe if the user can be sure that it is the bank that he sees in his web browser. If the user types in, but his communication is hi-jacked and a fake web-site (that pretends to be the bank web-site) sends the page information back to the user's browser, the fake web-page can send a fake public key to the user (for which the fake site owns a matching private key). The user will fill the form with his personal data and will submit the page. The fake web-page will get access to the user's data.

A certificate authority (CA) is an organization that stores public keys and their owners and every party in a communication trusts this organization (and knows its public key). When the user's web browser receives the public key from it also receives a digital signature of the key (with some more information, in a so-called X.509 certificate). The browser already possesses the public key of the CA and consequently can verify the signature, trust the certificate and the public key in it: since uses a public key that the certification authority certifies, a fake can only use the same public key. Since the fake does not know the corresponding private key, it cannot create the signature needed to verify its authenticity.

Q Python
Perhaps this android compatible python is named for its relation to
QR codes, which provides a means of moving source code into the
QPython environment and editor on the phone. One web note said this
technique was limited to "a few KB". I tried one online QR gen and it
had a 1000 char limit.
A better alternative might be Kivy. Oddly my QPython app seems able to
run Kivy!

Run with console mode ( Default mode, the same behavior as desktop or server computer's python )

SD cards

TF used to means Trans-Flash. Now that def is in all SD cards.

Secure Digital High Capacity (SDHC) format. capacities up to 32 GB

SDXC supports cards up to 2 TB (2048 GB)

The SD/SDHC/SDXC memory cards have a "Protected Area" on the card
for the SD standard's security function. The SD Formatter does
not format the "Protected Area". Please use appropriate
application software or SD-compatible device that provides
SD security function to format the "Protected Area" in the
memory card.

SDXC memory cards inserted in the direct SD slot on a computer
may require the installation of an SDXC driver.

SD Interface Devices

The following interface devices can be used to access SD/SDHC/SDXC
memory cards:
SD slot on computer
USB SD reader
PC Card, CardBus or ExpressCard SD adapter
Always confirm that the device is compatible with the SD, SDHC
or SDXC memory card before formatting.

(file) server

"A computer responsible for the central storage and management of data files so that other computers on the same network can access the files."

The subtle advantage (fgh) is that there is one source defining account names and passwords (authentication). This centralizes 'owner' and 'group' (authorization) definitions allowing all member machines to agree on who 'frank' is, regardless of which machine he logged into.

A file server may be dedicated or non-dedicated. A dedicated server is designed specifically for use as a file server, with workstations attached for reading and writing files and databases.

File servers may also be categorized by the method of access: Internet file servers are frequently accessed by File Transfer Protocol (FTP) or by HTTP (but are different from web servers, that often provide dynamic web content in addition to static files). Servers on a LAN are usually accessed by SMB/CIFS protocol (Windows and Unix-like) or NFS protocol (Unix-like systems).

Database servers, that provide access to a shared database via a database device driver, are not regarded as file servers as they may require Record locking.

Server Key Exchange
This is an optional step in which the server creates and
sends a temporary key to the client. This key can be used by the client to
encrypt the Client Key Exchange message later in the process. The step is only
required when the public key algorithm does not provide the key material necessary
to encrypt the Client Key Exchange message, such as when the server's certificate
does not contain a public key.

Secure File Transfer Protocol
(Yahoo has required this for last few years)

amazing, automated file transfer story:

160617: cp'g one file from canopus to pinot
on pinot, in cygwin
sftp frank@[path/file2copy (from the login dir)
makefile1    # when asked password
# it copied the file and logged itself out.

160617: cp'g one file from pinot to canopus
on pinot, in cygwin
sftp frank@
makefile1    # when asked password
> [cd someOtherDir]
> put localFilename
^d   or bye
You can also perform FTP through a browser. For example, bring up Internet Explorer and type in
            ftp://yourLoginName@IPaddress   //doesnt wk for me, pinot to canopus 160617
instead of a normal web page URL.

non-interactive-authentication, needed for scripting the transfer
# possibly needed for automation
-F ssh_config
    where ssh_config is a file for ssh(1)

-o ssh_option
    Can be used to pass options to ssh in the format used in ssh_config(5).
    This is useful for specifying options for which there is no separate
    sftp command-line flag. For example, to specify an alternate port use:
    sftp -oPort=24. For full details of the options listed below, and
    their possible values, see ssh_config(5).

/etc/ssh/ssh_config   system wide config file. provides defaults
ssh_config man page doesnt show a PASS; instead a

sftp [user@]host[:file ...]
    will retrieve files automatically if a non-interactive authentication
    method is used; otherwise it will do so after successful interactive

sftp [user@]host[:dir[/]]
    allows sftp to start in a remote directory.

sftp -b batchfile [user@]host
    allows for automated sessions using the -b option. In such cases,
    it is necessary to configure non-interactive authentication to
    obviate the need to enter a password at connection time (see sshd(8)
    and ssh-keygen(1) for details).

Scripting Layer for Android, SL4A, is an open source application that allows
programs written in a range of interpreted languages to run on Android. It
also provides a high level API that allows these programs to interact with
the Android device, making it easy to do stuff like accessing sensor data,
sending an SMS, rendering user interfaces and so on.

It's is really easy to install and it works on any stock Android device, so
you don't need to be root or anything like that.

Currently, the Scripting Layer supports Python, Perl, Ruby, Lua, BeanShell,
JavaScript and Tcl. It also provides access to the Android system shell,
which is actually just a minimal Linux shell.

You can find out more about the SL4A project from their website. (link below)

eg router uses parts with 1's; ignores 0's class A. 255 marks network #; rest is host # class B. 255s mark network #; rest is host # class C. 255s mark network #; rest is host # 0's always denote the host#. 1's mark network# bits and subnet # as described below
The 1st byte of the quartet determines the basic address _class_ and the default netmask. Any extra bits in the actual subnet mask can be used to determine the network #; this is called the "subnet". 172.22, for example, is a "class B" address which has as the netmask. If you defined as the mask, you can use the 3rd byte as a part of your network number. The result is . Routers will honor this scheme.

Tiny BarCodes, for p/arduino/rover/
idea is to make simple but short barcodes which can be read by a rover passing
overhead. The reader would likely be a line following device such as that on
the black chassis (SFE) vehicle. The small number extracted from the TBC could
be sent to Master which replies with a string identifying the location and any
related notes like
    "at . in __ cm, there's a curve (left/right), radius __, arcLength __ degrees"
    "at . in __ cm, there's a siding (implies 15 degree branch) (l/r) to other "
TBC needs to include direction info. like crossing edge __ means the TBC # is backwards.
    going 'wrong' direction means the curve could be behind ya. rover needs to include its rel direction in
    its inquiry to host ("master")

Arduino package for doing radio. section 32 of video. needed SPI.h, SD.h

160702 this lib deprecated! (always late for a party...) says:
This VirtualWire library has now been superceded by the RadioHead library RadioHead and its RH_ASK driver provides all the features supported by VirtualWire, and much more besides, including Reliable Datagrams, Addressing, Routing and Meshes.
VirtualWire is a library for Arduino, Maple and others that provides features to send short messages, without addressing, retransmit or acknowledgment, using ASK (amplitude shift keying).
All that is required is transmit data, receive data and (for transmitters, optionally) a PTT transmitter enable. Can also be used over various analog connections (not just a data radio), such as the audio channel of an A/V sender
It is intended to be compatible with the RF Monolithics ( Virtual Wire protocol, but this has not been tested.
Does not use the Arduino UART. Messages are sent with a training preamble, message length and checksum. Messages are sent with 4-to-6 bit encoding for good DC balance, and a CRC checksum for message integrity.
This library provides classes for
    VirtualWire: unaddressed, unreliable messages
Example Arduino programs are included to show the main modes of use.

(,netw,secr,)Web of Trust
Main article: Web of trust
An alternative approach to the problem of public authentication of public-key information is the
web-of-trust scheme, which uses self-signed certificates and third party attestations of those certificates.
The singular term "web of trust" does not imply the existence of a single web of trust, or
common point of trust, but rather one of any number of potentially disjoint "webs of trust".
Examples of implementations of this approach are PGP (Pretty Good Privacy) and GnuPG
(an implementation of OpenPGP, the standardized specification of PGP). Because PGP and implementations
allow the use of e-mail digital signatures for self-publication of public-key information, it is
relatively easy to implement one's own web of trust.

wireless security
from tomerge/docs/homeNetSecurity.txt
1) USE WPA2.
2) Disable the broadcast of your SSID by your wireless router.
3) Copy the MAC addresses of each of your computers and wireless devices into
   the MAC address table of your wireless router and then set the router to
   ENABLE ONLY those MAC addresses listed.
4) If you have 2 computers and 3 laptops and 2 wireless printers, ONLY create
   8 Internal IP addresses on the DHCP server of your wireless router. DO not
   create more than you need. If every IP address is in use, it's a good thing.

If you follow all the precautions I've listed, even seasoned hackers won't
break through into your wireless network.
There are so few people that actually perform all of these measures correctly.
There are tons of easier targets out there than those that manage to follow
these simple security rules.
