Activation | |
Connections can be temporarily deactivated, or they can break because of overly impatient firewalls dropping TCP connections. Where possible, libpqxx will try to re-activate these when resume using them, or you can wake them up explicitly. You probably won't need this feature, but you should be aware of it. | |

Prepared statements | |
PostgreSQL supports prepared SQL statements, i.e. statements that can be registered under a client-provided name, optimized once by the backend, and executed any number of times under the given name. Prepared statement definitions are not sensitive to transaction boundaries; a statement defined inside a transaction will remain defined outside that transaction, even if the transaction itself is subsequently aborted. Once a statement has been prepared, only closing the connection or explicitly "unpreparing" it can make it go away. Use the transaction classes' A special case is the nameless prepared statement. You may prepare a statement without a name. The unnamed statement can be redefined at any time, without un-preparing it first.

| void | prepare (const std::string &name, const std::string &definition) |
| Define a prepared statement. | |
| void | prepare (const std::string &definition) |

Transactor framework | |
See the transactor class template for more about transactors. To use the transactor framework, encapsulate your transaction code in a class derived from an instantiation of the pqxx::transactor template. Then, to execute it, create an object of your transactor class and pass it to one of the perform() functions here. The perform() functions may create and execute several copies of the transactor before succeeding or ultimately giving up. If there is any doubt over whether execution succeeded (this can happen if the connection to the server is lost just before the backend can confirm success), it is no longer retried and an in_doubt_error is thrown. Take care: no member functions will ever be invoked on the transactor object you pass into perform(). The object you pass in only serves as a "prototype" for the job to be done. The perform() function will copy-construct transactors from the original you passed in, executing the copies only. The original object remains "clean" in its original state. | |
| template<typename TRANSACTOR > | |
| void | perform (const TRANSACTOR &T, int Attempts) |

Capabilities | |
Some functionality is only available in certain versions of the backend, or only when speaking certain versions of the communications protocol that connects us to the backend. This includes clauses for SQL statements that were not accepted in older database versions, but are required in newer versions to get the same behaviour. | |

connection_base abstract base class; represents a connection to a database.
This is the first class to look at when you wish to work with a database through libpqxx. Depending on the implementing concrete child class, a connection can be automatically opened when it is constructed, or when it is first used, or somewhere inbetween. The connection is automatically closed upon destruction (if it hasn't been closed already).
To query or manipulate the database once connected, use one of the transaction classes (see pqxx/transaction_base.hxx) or preferably the transactor framework (see pqxx/transactor.hxx).
If a network connection to the database server fails, the connection will be restored automatically (although any transaction going on at the time will have to be aborted). This also means that any information set in previous transactions that is not stored in the database, such as temp tables or connection-local variables defined with PostgreSQL's SET command, will be lost. Whenever you create such state, either keept it local to one transaction, where possible, or inhibit automatic reactivation of the connection using the inhibit_reactivation() method.
When a connection breaks, you will typically get a broken_connection exception. This can happen at almost any point, and the details may depend on which connection class (all derived from this one) you use.
As a general rule, always avoid raw queries if libpqxx offers a dedicated function for the same purpose. There may be hidden logic to hide certain complications from you, such as reinstating session variables when a broken or disabled connection is reactivated.
Session capabilities.

explicitprotected |
| void pqxx::connection_base::activate | ( | ) |
Explicitly activate deferred or deactivated connection.
Use of this method is entirely optional. Whenever a connection is used while in a deferred or deactivated state, it will transparently try to bring itself into an activated state. This function is best viewed as an explicit hint to the connection that "if you're not in an active state, now would be a good time to get into one." Whether a connection is currently in an active state or not makes no real difference to its functionality. There is also no particular need to match calls to activate() with calls to deactivate().
Referenced by pqxx::internal::sql_cursor::sql_cursor().
| string pqxx::connection_base::adorn_name | ( | const std::string & | n | ) |
Suffix unique number to name to make it unique within session context.
Used internally to generate identifiers for SQL objects (such as cursors and nested transactions) based on a given human-readable base name.
References pqxx::to_string().
| int pqxx::connection_base::await_notification | ( | ) |
Wait for a notification to come in.
The wait may also be terminated by other events, such as the connection to the backend failing. Any pending or received notifications are processed as part of the call.
References pqxx::internal::wait_read().
| int pqxx::connection_base::await_notification | ( | long | seconds, |
| long | microseconds | ||
| ) |
Wait for a notification to come in, or for given timeout to pass.
The wait may also be terminated by other events, such as the connection to the backend failing. Any pending or received notifications are processed as part of the call.
References pqxx::internal::wait_read().
| int pqxx::connection_base::backendpid | ( | ) | const throw () |
Process ID for backend process.
Use with care: connections may be lost and automatically re-established without your knowledge, in which case this process ID may no longer be correct. You may, however, assume that this number remains constant and reliable within the span of a successful backend transaction. If the transaction fails, which may be due to a lost connection, then this number will have become invalid at some point within the transaction.
| void pqxx::connection_base::cancel_query | ( | ) |
Attempt to cancel the ongoing query, if any.
|
protected |
Referenced by pqxx::basic_connection< CONNECTPOLICY >::~basic_connection().
| const char * pqxx::connection_base::dbname | ( | ) |
Name of database we're connected to, if any.
| void pqxx::connection_base::deactivate | ( | ) |
Explicitly deactivate connection.
Like its counterpart activate(), this method is entirely optional. Calling this function really only makes sense if you won't be using this connection for a while and want to reduce the number of open connections on the database server. There is no particular need to match or pair calls to deactivate() with calls to activate(), but calling deactivate() during a transaction is an error.
| void pqxx::connection_base::disconnect | ( | ) | throw () |
Explicitly close connection.
| vector< errorhandler * > pqxx::connection_base::get_errorhandlers | ( | ) | const |
Return pointers to the active errorhandlers.
The entries are ordered from oldest to newest handler.
You may use this to find errorhandlers that your application wants to delete when destroying the connection. Be aware, however, that libpqxx may also add errorhandlers of its own, and those will be included in the list. If this is a problem for you, derive your errorhandlers from a custom base class derived from pqxx::errorhandler. Then use dynamic_cast to find which of the error handlers are yours.
The pointers point to the real errorhandlers. The container it returns however is a copy of the one internal to the connection, not a reference.
| int pqxx::connection_base::get_notifs | ( | ) |
Check for pending notifications and take appropriate action.
All notifications found pending at call time are processed by finding any matching receivers and invoking those. If no receivers matched the notification string, none are invoked but the notification is considered processed.
Exceptions thrown by client-registered receivers are reported using the connection's errorhandlers, but the exceptions themselves are not passed on outside this function.
| string pqxx::connection_base::get_variable | ( | const std::string & | Var | ) |
Read session variable.
Will try to read the value locally, from the list of variables set with the set_variable function. If that fails, the database is queried.
| error_verbosity pqxx::connection_base::get_verbosity | ( | ) | const throw () |
Retrieve current error verbosity.
| const char * pqxx::connection_base::hostname | ( | ) |
Address of server, or NULL if none specified (i.e. default or local)
| void pqxx::connection_base::inhibit_reactivation | ( | bool | inhibit | ) |
Disallow (or permit) connection recovery.
A connection whose underlying socket is not currently connected to the server will normally (re-)establish communication with the server whenever needed, or when the client program requests it (although for reasons of integrity, never inside a transaction; but retrying the whole transaction may implicitly cause the connection to be restored). In normal use this is quite a convenient thing to have and presents a simple, safe, predictable interface.
There is at least one situation where this feature is not desirable, however. Although most session state (prepared statements, session variables) is automatically restored to its working state upon connection reactivation, temporary tables and so-called WITH HOLD cursors (which can live outside transactions) are not.
Cursors that live outside transactions are automatically handled, and the library will quietly ignore requests to deactivate or reactivate connections while they exist; it does not want to give you the illusion of being back in your transaction when in reality you just dropped a cursor. With temporary tables this is not so easy: there is no easy way for the library to detect their creation or track their lifetimes.
So if your program uses temporary tables, and any part of this use happens outside of any database transaction (or spans multiple transactions), some of the work you have done on these tables may unexpectedly be undone if the connection is broken or deactivated while any of these tables exists, and then reactivated or implicitly restored before you are finished with it.
If this describes any part of your program, guard it against unexpected reconnections by inhibiting reconnection at the beginning. And if you want to continue doing work on the connection afterwards that no longer requires the temp tables, you can permit it again to get the benefits of connection reactivation for the remainder of the program.
| inhibit | should reactivation be inhibited from here on? |

Referenced by pqxx::basic_connection< CONNECTPOLICY >::basic_connection().
| bool pqxx::connection_base::is_open | ( | ) | const throw () |
Is this connection open at the moment?
| void pqxx::connection_base::perform | ( | const TRANSACTOR & | T, |
| int | Attempts | ||
| ) |
Perform the transaction defined by a transactor-based object.
Invokes the given transactor, making at most Attempts attempts to perform the encapsulated code. If the code throws any exception other than broken_connection, it will be aborted right away.
| T | The transactor to be executed. |
| Attempts | Maximum number of attempts to be made to execute T. |
| void pqxx::connection_base::perform | ( | const TRANSACTOR & | T | ) |
| const char * pqxx::connection_base::port | ( | ) |
Server port number we're connected to.
| void pqxx::connection_base::prepare | ( | const std::string & | name, |
| const std::string & | definition | ||
| ) |
Define a prepared statement.
The statement's definition can refer to a parameter using the parameter's positional number n in the definition. For example, the first parameter can be used as a variable "$1", the second as "$2" and so on.
Here's an example of how to use prepared statements. Note the unusual syntax for passing parameters: every new argument is a parenthesized expression that is simply tacked onto the end of the statement!
To save time, prepared statements aren't really registered with the backend until they are first used. If this is not what you want, e.g. because you have very specific realtime requirements, you can use the prepare_now()
function to force immediate preparation.
| name | unique name for the new prepared statement. |
| definition | SQL statement to prepare. |
| void pqxx::connection_base::prepare | ( | const std::string & | definition | ) |
Define a nameless prepared statement.
This can be useful if you merely want to pass large binary parameters to a statement without otherwise wishing to prepare it. If you use this feature, always keep the definition and the use close together to avoid the nameless statement being redefined unexpectedly by code somewhere else.
| void pqxx::connection_base::prepare_now | ( | const std::string & | name | ) |
Request that prepared statement be registered with the server.
If the statement had already been fully prepared, this will do nothing.
If the connection should break and be transparently restored, then the new connection will again defer registering the statement with the server. Since connections are never restored inside backend transactions, doing this once at the beginning of your transaction ensures that the statement will not be re-registered during that transaction. In most cases, however, it's probably better not to use this and let the connection decide when and whether to register prepared statements that you've defined.
| void pqxx::connection_base::process_notice | ( | const char | msg[] | ) | throw () |
Invoke notice processor function. The message should end in newline.
| void pqxx::connection_base::process_notice | ( | const std::string & | msg | ) | throw () |
Invoke notice processor function. Newline at end is recommended.
| int pqxx::connection_base::protocol_version | ( | ) | const throw () |
What version of the PostgreSQL protocol is this connection using?
The answer can be 0 (when there is no connection, or the libpq version being used is too old to obtain the information); 2 for protocol 2.0; 3 for protocol 3.0; and possibly higher values as newer protocol versions are taken into use.
If the connection is broken and restored, the restored connection could possibly a different server and protocol version. This would normally happen if the server is upgraded without shutting down the client program, for example.
Requires libpq version from PostgreSQL 7.4 or better.
| int pqxx::connection_base::server_version | ( | ) | const throw () |
What version of the PostgreSQL server are we connected to?
The result is a bit complicated: each of the major, medium, and minor release numbers is written as a two-digit decimal number, and the three are then concatenated. Thus server version 7.4.2 will be returned as the decimal number 70402. If there is no connection to the server, of if the libpq version is too old to obtain the information, zero is returned.
| void pqxx::connection_base::set_client_encoding | ( | const std::string & | Encoding | ) |
Set client-side character encoding.
Search the PostgreSQL documentation for "multibyte" or "character set encodings" to find out more about the available encodings, how to extend them, and how to use them. Not all server-side encodings are compatible with all client-side encodings or vice versa.
| Encoding | Name of the character set encoding to use |
| void pqxx::connection_base::set_variable | ( | const std::string & | Var, |
| const std::string & | Value | ||
| ) |
Set session variable.
Set a session variable for this connection, using the SET command. If the connection to the database is lost and recovered, the last-set value will be restored automatically. See the PostgreSQL documentation for a list of variables that can be set and their permissible values. If a transaction is currently in progress, aborting that transaction will normally discard the newly set value. Known exceptions are nontransaction (which doesn't start a real backend transaction) and PostgreSQL versions prior to 7.3.
| Var | Variable to set |
| Value | Value vor Var to assume: an identifier, a quoted string, or a number. |
| void pqxx::connection_base::set_verbosity | ( | error_verbosity | verbosity | ) | throw () |
Set session verbosity.
Set the verbosity of error messages to "terse", "normal" (i.e. default) or "verbose."
If "terse", returned messages include severity, primary text, and position only; this will normally fit on a single line. "normal" produces messages that include the above plus any detail, hint, or context fields (these might span multiple lines). "verbose" includes all available fields.
| void pqxx::connection_base::simulate_failure | ( | ) |
Make the connection fail.
Do not use this in normal programs. This is only meant for testing.
| int pqxx::connection_base::sock | ( | ) | const throw () |
Socket currently used for connection, or -1 for none. Use with care!
Query the current socket number. This is intended for event loops based on functions such as select() or poll(), where multiple file descriptors are watched.
Please try to stay away from this function. It is really only meant for event loops that need to wait on more than one file descriptor. If all you need is to block until a notification arrives, for instance, use await_notification(). If you want to issue queries and retrieve results in nonblocking fashion, check out the pipeline class.
| bool pqxx::connection_base::supports | ( | capability | c | ) | const throw () |
Does this connection seem to support the given capability?
 Obtaining it is quite fast (especially after the first time) and what's more, a capability may "suddenly" appear or disappear if the connection is broken or deactivated, and then restored. This may happen silently any time no backend transaction is active; if it turns out that the server was upgraded or restored from an older backup, or the new connection goes to a different backend, then the restored session may have different capabilities than were available previously.
Some guesswork is involved in establishing the presence of any capability; try not to rely on this function being exactly right.

Need help - Getting lost in all the information - want to get things working...
Dear all,
I'm working on the following setup:
3x emonTxV3.4 connected to a Raspi V1b via serial cable (2x with USB UART).
This Raspi (called emonhub-pi) forwards the packets via Ethernat cable to a central Raspi V2 (emonCMS-pi), running on SSD with a local emonHub / emonCMS installation.
The emonCMS-pi already does the job with wireless packets from emonTH devices.
As I found the time now to setup the emonhub-pi as a forwarder (first installation did the job well - but SD crashed) I updated to the newest preconfigured SD image "emonSD-17Jun2015.img" from emon website.
Here I did some basic setting (static IP, root Passwd, ...).
I successfully ping-ed the emonCMS-pi and connected via ssh - network connection seems to fit.
I looked at the serial console to see what the emonTxV3 NR1 is posting (USB serials not yet connected)
"10 513,25 510,44 -509,99 509,74 230,83" each 2s (Serial direct sketch)
My emonHub config file lists the following (that worked within the image before
[hub] loglevel = WARNING [reporters] [[emonCMS]] Type = EmonHubEmoncmsReporter [[[init_settings]]] [[[runtimesettings]]] url = http://<IP_ADDRESS>/emoncms apikey = ############################### [interfacers] [[SerialDirect]] Type = EmonHubSerialInterfacer [[[init_settings]]] com_port = /dev/ttyAMA0 com_baud = 9600 [[[runtimesettings]]] group = 210 frequency = 433 baseid = 15 [nodes]
Now the emonhub.log constantly gives me this warning:
2016-04-16 19:05:08,867 WARNING MainThread SerialDirect thread is dead
Rebooting the the pi does not help
I'm running out of ideas. As I don't have a emonPi (only a Pi with emonhub running) I guess I could use an other image. But which to use ?
The central emonCMS is version 9.4
Thanks for any help in advance.
Re: Need help - Getting lost in all the information - want to get things working...
I'm not an expert - hopefully one will be along soon...
But I think you might need to install using the raspberry pi installation guide rather than using the SD image. Certainly worth a try.

Re: Need help - Getting lost in all the information - want to get things working...
Was the direct serial connection working before you re-imaged? Its been a while since I last did a build using a direct serial connection between the emontx and emonpi - things have moved on quite a bit since then in terms of emoncms and emonhub version. Can you catch the point in the logs where the SerialDirect thread dies? There may be some more clues there.
Can I rename your thread to reflect the topic perhaps: "Need help, emonhub with emontx to pi direct serial connection"?
Re: Need help - Getting lost in all the information - want to get things working...
1st step would be to set emonhub's "loglevel = DEBUG" in emonhub.conf rather than WARNING which will give you more info.
The "WARNING MainThread SerialDirect thread is dead" error message can only be found in the emon-pi variant of emonhub and yet the emonhub.conf you have is for the original version of emonhub. There are no reporters in the emon-pi variant, the "EmonHubEmoncmsReporter" was replaced with a "EmonHubEmoncmsHTTPInterfacer".
There is also an absence of the routing settings (the to and from) required for the interfacers in that variant.
While you are in the conf you can get rid of the group, frequency and baseid settings as they are not used for serial direct, only needed for RFM networks, this won't be effecting the issues you have though.
Your example packet "10 513,25 510,44 -509,99 509,74 230,83" shows some comma's, is this a typo or a regional thing? emonhub will expect (depending on version) a frame in one of 2 forms, a nodeid followed by space separated decimal values eg "10 513.25 510.44 -509.99 509.74 230.83" or (less likely) a node id followed by space seperated "byte values" ie values between 0 and 255 to be reconstructed into full values using datacodes, either way the comma's could cause the packets to be discarded unless there is a "regional" adjustment made at the recieving end (emonhub) too.
The emonhub log should show you exactly whats happening there if you change the loglevel.
Also be aware that emoncms.org will probally block your address/device if you are posting at 2s intervals, the recommended rate is 10s, but you should be ok with a local install.

Re: Need help - Getting lost in all the information - want to get things working...
I am also having trouble with the "SerialDirect thread is dead" message when trying to connect via serial to the emon-pi emonHub variant 1.1.
The Arduino I am using works when connected via serial to my older emonHub, running the emonSD-13-03-15.img image that provided me with "emonHub Pre-Release Development Version (rc1.2)".
With the identical hardware setup, but running the emonSD-29Mar16 release candidate 2 image, I get the errors below.
First, my interfacer config:
And here is the result:
Re: Need help - Getting lost in all the information - want to get things working...
Can you provide more info on the sketch and/or serial data ?
The "SerialDirect thread is dead" is a simple check written into the main core of emonhub to avoid a situation where an interfacer thread crashes out without any notice and it's then unknown if the interfacer is "dead" or just quiet.
Basically the thread is crashing and there is no clues as to why since the error handling and logging is "a little thin" in this version.
As in the example above it could well be the incoming data just isn't perfect and it's not being handled the same way it would be in the original version.

My best guess is the text from the setup() isn't being caught and removed so when the interfacer tries to extract the node id it fails as there is no int present. The original emonhub's serial interfacer had basic input sanitation where as the raw data is passed without any checks in this variant.
Any attempts to edit the emonhub code could cause issues with the emonpi update script so your best course of action is a quick edit to the sketch to remove any printing of non-numeric data. Primarily in the setup() but since the loop() "if (Serial.available() > 0)" code block is not useful without proper integration within emonhub, perhaps a custom Monteino interfacer. I would probably cut that away too, replacing it with some hardcoded "options" if required.
if you want to implement something a little grander I will help with some pointers but if you plan to keep updating via the emonpi update script this is the easiest option unless the changes are made upstream.

Re: Need help - Getting lost in all the information - want to get things working...
Thanks, Paul! That was it. I hadn't bothered to clean up the mess I had made of that sketch because it was working on my old emonHub. I cleaned it up and removed all the extraneous serial printing. Now it works perfectly.
I did notice that emonhub is adding an RSSI value to that input, which I am not sending it. It sets it to zero and displays it in the inputs view. Is there some assumption in this version of emonhub that there is always an RSSI value?
Regarding implementing something a little grander, here is what I am envisioning: using my emonHub+Moteino as an internet-of-things base station. I.e uing the OpenHAB app to set a switch, which triggers an MQTT message, which Node-RED catches. Node-RED then sends a command over serial (USB) to the Moteino base station, which radios a remote Moteino to do something. I'd be interested in any pointers you might have. Like, is that even a good way to approach it? And, does Node-RED have an easy way to write serial data to the USB port of the Pi?
Thanks again!

Re: Need help - Getting lost in all the information - want to get things working...
The other thing that appears to cause the "MainThread SerialDirect thread is dead" warning is simply connecting or disconnecting the device plugged into the USB port. And once that warning starts up, it repeats at least once every second. It would be nice, if I could suggest it, if the input sanitation from the older emonHub was brought forward to this one.
I found that simply restarting emonHub with "sudo service emonhub restart" was not enough to resolve "thread is dead" warning. I had to reboot the Pi on which it is running.
I would second the earlier motion to rename this thread: "WARNING MainThread SerialDirect thread is dead" and in my opinion we could add [SOLVED]. For now, the trick is to be very careful that you reboot your Pi running emonHub when you plug in a USB serial input, and you must make sure there is nothing printing to that serial port other than nice, clean input messages in the expected format.
Re: Need help - Getting lost in all the information - want to get things working...
Hi Brandon
emonhub should be robust enough not to fail due to incorrect serial data, ideally the sketch should identify itself so that down the line you know what sketch and version you are running. The removal of all the serial prints is not an acceptable fix IMO it is a quick and dirty workaround but if it gets you up and running that's good to know.
Yes the emon-pi variant assumes everything has an rssi, the original emonhub only passes the rssi if a valid rssi is attached to an incoming RFM packet, but this variant is very different in many ways.
If restarting emonhub doesn't resolve the "WARNING MainThread SerialDirect thread is dead" issue then there is something else in the mix causing an issue.
Any serial port (gpio or usb) can only have 2 devices using those lines, for that reason you should not have node-red connecting to the same port/device as emonhub. This maybe the reason you need to reboot the Pi if there is anything else accessing the same serial port, restarting emonhub will not free the serial port fo emonhubs exclusive use.
Ideally you should be able to configure emonhub to listen for the openhab mqtt and act "directly" with the monteino. I am not saying you cannot use node-red, many do but, you cannot have multiple softwares connected to the one device and therefore openhab should connect directly with emonhub or of you go to node-red then node-red should go to emonhub which may be pointless.
I am not opposed to the thread name being changed at all, perhaps "WARNING MainThread SerialDirect thread is dead" would be more appropriate but since the issue is far from solved I would be opposed to the [solved] tag especially as there are many, many reasons that could cause that catch all error, it is not the sort of error that will ever be solved for everyone.

Re: Need help - Getting lost in all the information - want to get things working...
Hi all,
thanks for all the good tips.
I will give them a try now - didn't found the time to go on with it until now.
First of all I will change the setting for log level and check the arduino script for the period/commata issue. It might be have been me, who copied the period things to Notepad++ and change all periods for commas (excel import required in germany)
In the end, it seems I have to update my emonCMS / emonHub Setup on the central Pi to support the new method.
I really don't like to make a "from the scratch" setup, since everything for ssd and settings is working fine.
I'll get back with more info soon.
If you'd like to rename the thread - feel free. Serial direct / serial thread dead / emonHub update issue might be good chunks for a header.
Cheers
Christian

12 students took the class, each completing some of the assignments. Can you determine which students completed which work?
- Every student finished at least one assignment, but no student finished every assignment.
- Every assignment was completed by at least one student, but no assignment was completed by every student.
- Fran completed exactly two assignments.
- Emily did not complete any pair of consecutive assignments.
- Beth and Georgia completed the same number of assignments.
- The assignments completed by Anne are a proper subset of the assignments completed by Emily, and Emily's assignments are a proper of subset of those completed by Katherine.
- The number of students who completed the first assignment times the number of students who completed the second assignment equals 20.
- Joan completed two more assignments than Helen did.
- Caroline completed exactly three assignments; the two she didn't do were consecutive.
- Denise and Ione were perfect opposites--any assignment finished by Denise was skipped by Ione, and vice versa.
- When the students are listed alphabetically, in every pair of consecutive students (that is, Anne/Beth, Beth/Caroline, Caroline/Denise, et cetera), at least one completed the fourth assignment. The same is true of the fifth assignment.
- Only four students completed exactly one of assignments 4 and 5.
- An even number of students completed the third assignment.
- Anne and Denise both completed the fifth (or least signficant) assignment; no other assignment was completed by both of them.
- The first (or most significant) assignment was completed by four students, all between Caroline and Georgia (inclusive) alphabetically.
- Leah completed the second assignment if and only if Anne did not complete the fourth.
- If you think of the assignments as a binary number, where finishing an assignment is a 1 and not finishing is a 0 (but why would you?), then Beth's number is the only palindrome.
- Either Anne and Ione both completed exactly one assignment, or they both completed the second assignment.
- Of Emily, Fran, and Georgia, exactly one did not complete the fourth assignment.
- Either Leah completed all of the odd numbered assignments OR Ione completed exactly one of the first and second assignments.
- Beth completed the second assignment; all of the other students who did so form one contiguous segment of the class when listed alphabetically.
- The assignments completed by Katherine form a consecutive block.

Chapter 3 Introduction to Git
You ideally will already have been trough a basic introduction to Git. The RSE introduction to Git materials can be found at: https://ooominds.github.io/RSE_induction/
As a basic, the first thing you need to do is to configure Git so that it knows who you are. From your shell / terminal type:
git config --global user.name 'Tania Allard'
git config --global user.email<EMAIL_ADDRESS>git config --global --list
substituting your name and the email associated with your GitHub account.
3.1 More about git config
From RStudio, go to Tools > Shell and tell Git your name and GitHub email by typing (use your own name and email).
Note: If you are on Windows, check the title bar of the shell that was opened! If you see cmd.exe
at the end of the status bar, this is the Windows Command Prompt. If you instead see MINGW64
at the beginning, you have successfully opened Git Bash!
Note: If you are not in an R Project that is version controlled with git, Tools > Shell will open Windows Command Prompt. If this is the case and RStudio still opens cmd.exe
, check Tools > Global Options > Git/SVN and tick the box for “Use Git Bash as shell for Git projects”. You may need to restart RStudio.
git config --global user.name 'Tania Allard'
- This does NOT have to be your GitHub username, although it can be. Another good option is your actual first name and last name. Your commits will be labelled with this name, so this should be informative to potential collaborators.
git config --global user.email<EMAIL_ADDRESS>- This must be the email that you used to sign up for GitHub.
These commands return nothing. You can check that Git understood what you typed by looking at the output of git config --global --list
.
3.2 Shell in the latest version of Rstudio
The instructions above tell you to find Tools > Shell to open up an instance of your own shell. If you have the latest version of RStudio installed you will find that a terminal is permanently running next to where your console is:
You should then be able to use this as you would normally use your shell in your Operative System.

background
The background shorthand CSS property sets all background style properties at once, such as color, image, origin and size, repeat method, and others. The property is a shorthand that sets the following properties in a single declaration: background-clip, background-color, background-image, background-origin, background-position, background-repeat, background-size, and background-attachment. As with all shorthand properties, any omitted sub-values will be set to their initial value.
- Syntax
- Values
/* Using a */
background: green;
/* Using a and */
background: url("test.jpg") repeat-y;
/* Using a and */
background: border-box red;
/* A single image, centered and scaled */
background: no-repeat center/80% url("../img/image.png");
See background-attachment
See background-clip and background-origin
See background-color
See background-image
See background-position
See background-repeat
See background-size.
border
he border CSS property sets an element's border. It's a shorthand for border-width, border-style, and border-color. As with all shorthand properties, any omitted sub-values will be set to their initial value. Importantly, border cannot be used to specify a custom value for border-image, but instead sets it to its initial value, i.e., none.  To make them different from each other, however, you can use the longhand border-width, border-style, and border-color properties, which accept different values for each side. Alternatively, you can target one border at a time with the physical (e.g., border-top ) and logical (e.g., border-block-start) border properties.
- Syntax
- Example
/* style */
border: solid;
/* width | style */
border: 2px dotted;
/* style | color */
border: outset #f33;
/* width | style | color */
border: medium dashed green;
/* Global values */
border: inherit;
border: initial;
border: unset;
div {
border: 0.5rem outset pink;
outline: 0.5rem solid khaki;
box-shadow: 0 0 0 2rem skyblue;
border-radius: 12px;
font: bold 1rem sans-serif;
margin: 2rem;
padding: 1rem;
outline-offset: 0.5rem;
}
box-shadow
The box-shadow CSS property adds shadow effects around an element's frame. You can set multiple effects separated by commas. A box shadow is described by X and Y offsets relative to the element, blur and spread radii, and color. The box-shadow property enables you to cast a drop shadow from the frame of almost any element. If a border-radius is specified on the element with a box shadow, the box shadow takes on the same rounded corners. The z-ordering of multiple box shadows is the same as multiple text shadows (the first specified shadow is on top). Box-shadow generator is an interactive tool allowing you to generate a box-shadow.
- Formal Syntax
/* offset-x | offset-y | color */
box-shadow: 60px -16px teal;
/* offset-x | offset-y | blur-radius | color */
box-shadow: 10px 5px 5px black;
/* offset-x | offset-y | blur-radius | spread-radius | color */
box-shadow: 2px 2px 2px 1px rgba(0, 0, 0, 0.2);
/* inset | offset-x | offset-y | color */
box-shadow: inset 5em 1em gold;
/* Any number of shadows, separated by commas */
box-shadow: 3px 3px red, -1em 0 0.4em olive;
/* Global keywords */
box-shadow: inherit;
box-shadow: initial;
box-shadow: unset;

Group Progress
Worked together on figuring out how individual parts will come together via Java, Android Studio, C++, and Bluetooth. Started with how Android phone will get data from hardware in order to make the app work properly.
Individual Progress
Robert Keller: Continued working on the analysis section of the phase vocoder and has started on the synthesis section. Continuing in Matlab and will use Simulink to convert filters and waves into C++ functions.
Julian Trulear: Finished soldering pins on Bluefruit LE and has also finished soldering pins on the LSM9DS0 (gyroscope). Started routing tiny wires from Bluefruit to LSM9DS0 for correct power and data transfer. Tiny wires because want as minimal obstructions as possible for hardware.
David Yuan: Created a simple UI for the application as we want it to not be distracting for the user. Focusing more on the functionality and processing inside the app, e.g. how the modes will work in Android programming.
Goals for Next Week
Want analysis section of the phase vocoder to be done as well as a decent chunk of the synthesis section. Want all wires to be hooked up correctly and data to be transferred in hardware. Want UI to be functional on the phone and to start transferring data between the phone and hardware.

Young Wolves star switches allegiance to Wales as he joins Man Utd and Liverpool teenagers
Wales have a raft of youngsters who could make the grade at senior level in the near future
by Ian MitchelmorePaul Bodin has confirmed Wolves youngster Terry Taylor has switched his allegiance from Scotland to Wales.
The 18-year-old played for Wales Under-15s but went on to represent the Scots' Under-17 side on nine occasions before turning out for their Under-18s.
But Aberdeen-born Taylor - whose mother Morag is from Cardiff - was included in the senior Wales set-up for a training camp prior to their Euro 2020 qualifiers with Croatia and Hungary in June.
He has since been included in the squad for Wales' UEFA U21 Championship qualifier with Bosnia & Herzegovina at Wrexham's Racecourse Ground on Tuesday.
And Bodin admits he's delighted that Taylor - who made his first team debut for Wolves against Aston Villa earlier this season - has joined a long list of players who have opted to represent the Red Dragons over a different nation.
"Terry came into a training camp in May with Ryan Giggs," said Bodin.
"He did really well and he's progressing well at Wolves. He used to play for Scotland, he's decided to change his allegiance to Wales, which is great for us.
"We're really pleased with him but the trouble has been is that he's had a lot of injuries from pre-season.
"He went away to China on their first-team tour, picked up an ankle injury and unfortunately that continued into the season.
"But in the last couple of weeks he's picked up form, he's played regularly and came on for the first-team in the Carabao Cup at Aston Villa.
"I've not actually worked with him yet but I've seen him train with the first-team squad.
"I remember him playing against us in the Under-17s at Llanelli a few years ago - he's a big strong powerful player.
"But he looks a lot more mobile now in his play. He'll be a big asset for us and we're delighted he's changed allegiance."
Neco Williams has remained with the Under-19s, despite a clamour for him to move up to Bodin's Under-21s squad following his impressive debut for Liverpool against Arsenal.
The right-back made his first team bow for Jurgen Klopp's side in the Carabao Cup clash with the Gunners last month, with Bodin admitting his efforts may well have surprised many people behind the scenes at Anfield.
Dylan Levitt was once again included in the senior set-up for the crunch double header with Azerbaijan and Hungary.
However, Bodin has said the attacker - who recently signed a new long-term contract with Manchester United - could drop down to the Under-21s again in the near future.
Elsewhere, goalkeeper George Ratcliffe has impressed since joining Cymru Premier outfit Barry Town United on loan from Cardiff City.
And he has remained an integral figure in the age grade sides with Wales.
However, the Under-21s will be without Liverpool ace Ben Woodburn who suffered a foot injury during his loan stint with Oxford United.
"He was going to drop down into the 21s and get some good games for us," said Bodin.
"On the eve of that he broke his metatarsal against Accrington Stanley.
"It's a huge blow for us and a huge blow for him. We wish him a speedy recovery.
"He's been big part of Oxford's success this season, playing lots of games which is important for his development."
Kick-off for the Under-21s fixture in Wrexham is at 4pm on Tuesday.

Provides the classes necessary to provide a spatial reasoning model.The model is based on blocks (rectangles) which are all of a single colour (each pixel has the same RGB value). There are no overlaps and no touching.
The model needs to be point based, though I need to decide what that actually means!


| Interface | Description |
|---|---|
| AreaHyperlinksRenderable |
Image renderer able to produce image maps.
|
| DataRenderable |
The
DataRenderable interface has a method called
DataRenderable.getData(JasperReportsContext) ,
which gets called by the engine each time it needs the actual image data either to embed it
directly into the exported documents, or to use it to draw the image or the graphic onto a device
or graphic context. |
| DimensionRenderable |
This interface is implemented by renderable objects that want to provide a dimention for the graphics they render,
usually by also implementing the
Graphics2DRenderable interface. |
| Graphics2DRenderable |
This interface has a method called
Graphics2DRenderable.render(JasperReportsContext, Graphics2D, Rectangle2D) ,
which gets called by the engine each time it needs to draw the image
on a given device or graphic context. |
| Renderable |
Provides functionality for image rendering.
|
| RenderToImageAwareRenderable |
This interface should be implemented by renderable object which want to benefit from better resolution and control
the way the graphic context is created when they are converted to image data, during export to certain document formats.

| systemfonts-package {systemfonts} | R Documentation |
Provides system native access to the font catalogue. As font handling varies between systems it is difficult to correctly locate installed fonts across different operating systems. The 'systemfonts' package provides bindings to the native libraries on Windows, macOS and Linux for finding font files that can then be used further by e.g. graphic devices. The main use is intended to be from compiled code but 'systemfonts' also provides access from R.

Undeniably one of my favorite programs is Excell (or, the one I use more frequently, Google Sheets).
A very unexpected interest of mine that I picked up through my college career is 3D Modeling and Animation. I caught on quite quickly and sought more and more techniques as to better expand my creative outlets.
I find it very important to be well versed in User Interface Design and Web Development. I have experience in HTML, CSS, and various workflows that are showcased in these projects.
Before I capitalized on Digital Arts, my means of getting into the Game Design field was through code. I came into college as a Software Engineer, taking various classes in highschool including AP Computer Science.

Data type formatting functions provide an easy way to convert values from one data type to another. For each of these functions, the first argument is always the value to be formatted and the second argument contains the template for the new format. Amazon Redshift supports several data type formatting functions.
