This guide provides a practical recipe for implementing vec_ptype2()
and vec_cast()
methods for coercions of data frame subclasses. Related
topics:
For an overview of the coercion mechanism in vctrs, see
?theory-faq-coercion
.
For an example of implementing coercion methods for simple vectors,
see ?howto-faq-coercion
.
Coercion of data frames occurs when different data frame classes are
combined in some way. The two main methods of combination are currently
row-binding with vec_rbind()
and col-binding with
vec_cbind()
(which are in turn used by a number of
dplyr and tidyr functions). These functions take multiple data frame
inputs and automatically coerce them to their common type.
vctrs is generally strict about the kind of automatic coercions that are performed when combining inputs. In the case of data frames we have decided to be a bit less strict for convenience. Instead of throwing an incompatible type error, we fall back to a base data frame or a tibble if we don’t know how to combine two data frame subclasses. It is still a good idea to specify the proper coercion behaviour for your data frame subclasses as soon as possible.
We will see two examples in this guide. The first example is about a data frame subclass that has no particular attributes to manage. In the second example, we implement coercion methods for a tibble subclass that includes potentially incompatible attributes.
To implement methods for generics, first import the generics in your namespace and redocument:
#' @importFrom vctrs vec_ptype2 vec_cast NULL
Note that for each batches of methods that you add to your package, you need to export the methods and redocument immediately, even during development. Otherwise they won’t be in scope when you run unit tests e.g. with testthat.
Implementing double dispatch methods is very similar to implementing
regular S3 methods. In these examples we are using roxygen2 tags to
register the methods, but you can also register the methods manually in
your NAMESPACE file or lazily with s3_register()
.
Most of the common type determination should be performed by the parent
class. In vctrs, double dispatch is implemented in such a way that you
need to call the methods for the parent class manually. For
vec_ptype2()
this means you need to call df_ptype2()
(for data frame
subclasses) or tib_ptype2()
(for tibble subclasses). Similarly,
df_cast()
and tib_cast()
are the workhorses for vec_cast()
methods
of subtypes of data.frame
and tbl_df
. These functions take the union
of the columns in x
and y
, and ensure shared columns have the same
type.
These functions are much less strict than vec_ptype2()
and
vec_cast()
as they accept any subclass of data frame as input. They
always return a data.frame
or a tbl_df
. You will probably want to
write similar functions for your subclass to avoid repetition in your
code. You may want to export them as well if you are expecting other
people to derive from your class.
data.table
exampleThis example is the actual implementation of vctrs coercion methods for
data.table
. This is a simple example because we don’t have to keep
track of attributes for this class or manage incompatibilities. See the
tibble section for a more complicated example.
We first create the dt_ptype2()
and dt_cast()
helpers. They wrap
around the parent methods df_ptype2()
and df_cast()
, and transform
the common type or converted input to a data table. You may want to
export these helpers if you expect other packages to derive from your
data frame class.
These helpers should always return data tables. To this end we use the
conversion generic as.data.table()
. Depending on the tools available
for the particular class at hand, a constructor might be appropriate as
well.
dt_ptype2 <- function(x, y, ...) { as.data.table(df_ptype2(x, y, ...)) } dt_cast <- function(x, to, ...) { as.data.table(df_cast(x, to, ...)) }
We start with the self-self method:
#' @export vec_ptype2.data.table.data.table <- function(x, y, ...) { dt_ptype2(x, y, ...) }
Between a data frame and a data table, we consider the richer type to be
data table. This decision is not based on the value coverage of each
data structures, but on the idea that data tables have richer behaviour.
Since data tables are the richer type, we call dt_type2()
from the
vec_ptype2()
method. It always returns a data table, no matter the
order of arguments:
#' @export vec_ptype2.data.table.data.frame <- function(x, y, ...) { dt_ptype2(x, y, ...) } #' @export vec_ptype2.data.frame.data.table <- function(x, y, ...) { dt_ptype2(x, y, ...) }
The vec_cast()
methods follow the same pattern, but note how the
method for coercing to data frame uses df_cast()
rather than
dt_cast()
.
Also, please note that for historical reasons, the order of the classes
in the method name is in reverse order of the arguments in the function
signature. The first class represents to
, whereas the second class
represents x
.
#' @export vec_cast.data.table.data.table <- function(x, to, ...) { dt_cast(x, to, ...) } #' @export vec_cast.data.table.data.frame <- function(x, to, ...) { # `x` is a data.frame to be converted to a data.table dt_cast(x, to, ...) } #' @export vec_cast.data.frame.data.table <- function(x, to, ...) { # `x` is a data.table to be converted to a data.frame df_cast(x, to, ...) }
With these methods vctrs is now able to combine data tables with data frames:
vec_cbind(data.frame(x = 1:3), data.table(y = "foo")) #> x y #> 1: 1 foo #> 2: 2 foo #> 3: 3 foo
In this example we implement coercion methods for a tibble subclass that carries a colour as a scalar metadata:
# User constructor my_tibble <- function(colour = NULL, ...) { new_my_tibble(tibble::tibble(...), colour = colour) } # Developer constructor new_my_tibble <- function(x, colour = NULL) { stopifnot(is.data.frame(x)) tibble::new_tibble( x, colour = colour, class = "my_tibble", nrow = nrow(x) ) } df_colour <- function(x) { if (inherits(x, "my_tibble")) { attr(x, "colour") } else { NULL } } #'@export print.my_tibble <- function(x, ...) { cat(sprintf("<%s: %s>\n", class(x)[[1]], df_colour(x))) cli::cat_line(format(x)[-1]) }
This subclass is very simple. All it does is modify the header.
red <- my_tibble("red", x = 1, y = 1:2) red #> <my_tibble: red> #> x y #> <dbl> <int> #> 1 1 1 #> 2 1 2 red[2] #> <my_tibble: red> #> y #> <int> #> 1 1 #> 2 2 green <- my_tibble("green", z = TRUE) green #> <my_tibble: green> #> z #> <lgl> #> 1 TRUE
Combinations do not work properly out of the box, instead vctrs falls back to a bare tibble:
vec_rbind(red, tibble::tibble(x = 10:12)) #> # A tibble: 5 x 2 #> x y #> <dbl> <int> #> 1 1 1 #> 2 1 2 #> 3 10 NA #> 4 11 NA #> 5 12 NA
Instead of falling back to a data frame, we would like to return a
<my_tibble>
when combined with a data frame or a tibble. Because this
subclass has more metadata than normal data frames (it has a colour), it
is a supertype of tibble and data frame, i.e. it is the richer type.
This is similar to how a grouped tibble is a more general type than a
tibble or a data frame. Conceptually, the latter are pinned to a single
constant group.
The coercion methods for data frames operate in two steps:
They check for compatible subclass attributes. In our case the tibble colour has to be the same, or be undefined.
They call their parent methods, in this case
tib_ptype2()
and tib_cast()
because we have a subclass of tibble. This eventually calls the data
frame methods df_ptype2()
and
tib_ptype2()
which match the columns and their
types.
This process should usually be wrapped in two functions to avoid repetition. Consider exporting these if you expect your class to be derived by other subclasses.
We first implement a helper to determine if two data frames have
compatible colours. We use the df_colour()
accessor which returns
NULL
when the data frame colour is undefined.
has_compatible_colours <- function(x, y) { x_colour <- df_colour(x) %||% df_colour(y) y_colour <- df_colour(y) %||% x_colour identical(x_colour, y_colour) }
Next we implement the coercion helpers. If the colours are not
compatible, we call stop_incompatible_cast()
or
stop_incompatible_type()
. These strict coercion semantics are
justified because in this class colour is a data attribute. If it were
a non essential detail attribute, like the timezone in a datetime, we
would just standardise it to the value of the left-hand side.
In simpler cases (like the data.table example), these methods do not
need to take the arguments suffixed in _arg
. Here we do need to take
these arguments so we can pass them to the stop_
functions when we
detect an incompatibility. They also should be passed to the parent
methods.
#' @export my_tib_cast <- function(x, to, ..., x_arg = "", to_arg = "") { out <- tib_cast(x, to, ..., x_arg = x_arg, to_arg = to_arg) if (!has_compatible_colours(x, to)) { stop_incompatible_cast( x, to, x_arg = x_arg, to_arg = to_arg, details = "Can't combine colours." ) } colour <- df_colour(x) %||% df_colour(to) new_my_tibble(out, colour = colour) } #' @export my_tib_ptype2 <- function(x, y, ..., x_arg = "", y_arg = "") { out <- tib_ptype2(x, y, ..., x_arg = x_arg, y_arg = y_arg) if (!has_compatible_colours(x, y)) { stop_incompatible_type( x, y, x_arg = x_arg, y_arg = y_arg, details = "Can't combine colours." ) } colour <- df_colour(x) %||% df_colour(y) new_my_tibble(out, colour = colour) }
Let’s now implement the coercion methods, starting with the self-self methods.
#' @export vec_ptype2.my_tibble.my_tibble <- function(x, y, ...) { my_tib_ptype2(x, y, ...) } #' @export vec_cast.my_tibble.my_tibble <- function(x, to, ...) { my_tib_cast(x, to, ...)
The methods for combining our class with tibbles follow the same pattern. For ptype2 we return our class in both cases because it is the richer type:
#' @export vec_ptype2.my_tibble.tbl_df <- function(x, y, ...) { my_tib_ptype2(x, y, ...) } #' @export vec_ptype2.tbl_df.my_tibble <- function(x, y, ...) { my_tib_ptype2(x, y, ...) }
For cast are careful about returning a tibble when casting to a tibble.
Note the call to vctrs::tib_cast()
:
#' @export vec_cast.my_tibble.tbl_df <- function(x, to, ...) { my_tib_cast(x, to, ...) } #' @export vec_cast.tbl_df.my_tibble <- function(x, to, ...) { tib_cast(x, to, ...) }
From this point, we get correct combinations with tibbles:
vec_rbind(red, tibble::tibble(x = 10:12)) #> <my_tibble: red> #> x y #> <dbl> <int> #> 1 1 1 #> 2 1 2 #> 3 10 NA #> 4 11 NA #> 5 12 NA
However we are not done yet. Because the coercion hierarchy is different from the class hierarchy, there is no inheritance of coercion methods. We’re not getting correct behaviour for data frames yet because we haven’t explicitly specified the methods for this class:
vec_rbind(red, data.frame(x = 10:12)) #> # A tibble: 5 x 2 #> x y #> <dbl> <int> #> 1 1 1 #> 2 1 2 #> 3 10 NA #> 4 11 NA #> 5 12 NA
Let’s finish up the boiler plate:
#' @export vec_ptype2.my_tibble.data.frame <- function(x, y, ...) { my_tib_ptype2(x, y, ...) } #' @export vec_ptype2.data.frame.my_tibble <- function(x, y, ...) { my_tib_ptype2(x, y, ...) } #' @export vec_cast.my_tibble.data.frame <- function(x, to, ...) { my_tib_cast(x, to, ...) } #' @export vec_cast.data.frame.my_tibble <- function(x, to, ...) { df_cast(x, to, ...) }
This completes the implementation:
vec_rbind(red, data.frame(x = 10:12)) #> <my_tibble: red> #> x y #> <dbl> <int> #> 1 1 1 #> 2 1 2 #> 3 10 NA #> 4 11 NA #> 5 12 NA

As part of our experience at DBC (and our future experience as developers), we'll often be asked to research and learn new concepts or even languages. Previously, we were instructed not to use recursion to solve any of our challenges, but now we've been given an opportunity to research new concepts, and I thought this would be a good opportunity to cover recursion.
In Ruby, recursion is the act of calling a method within a method. As an example:
def countdown(integer)
return if integer.zero?
puts integer
countdown(integer-1)
end
countdown(5)
5
4
3
2
1
In the above code, we set a base case of if integer.zero?. We then puts the integer use the countdown method within itself to puts integers down to 1.


Check out this antique rocking horse, which is helping raise cash for sick kids
The horse is around 50 years old and has been fully refurbished by Evelyn McLare.
by Michael Pringle, https://www.dailyrecord.co.uk/authors/michael-pringle/Sick children stuck in hospital over the festive period could be rocking around the Christmas tree thanks to the generosity of the mum of a Wishaw business woman.
Evelyn McLare spotted a child’s vintage rocking horse at auction and thought she could use it to benefit two worthy causes.
After submitting a successful bid for the horse she lovingly restored it to its former glory.
It is now taking pride of place on the premises of a Coltness business.
Evelyn’s daughter, Ashleigh Hamilton-Thompson and her partner Paul run Studio 1, a tattoo studio and barbers business.
They are encouraging parents to bring their children in and for a minimum £1 donation they can sit on the refurbished rocking horse, and have their photos taken.
But that’s not all, everyone who donates will be given a raffle ticket with proceeds going to the Les Hoey MBE DreamMaker Foundation.
Evelyn said: “I sometimes go to auctions and pick up antiques. I saw this amazing rocking horse, it is beautiful and I thought that’s worth a fair bit of money.
“I was finishing refurbing it and didn’t want to just sell it on again, it’s vintage and must be around 50 years old.
“My daughter Ashleigh owns Studio 1 and we decided we could raise money for Les’s charity.
“We thought we could also donate the rocking horse to the children’s hospital for Christmas. The idea is the children can come in to the shop and have their pictures taken on the magic pony.
“Every time a child rides the pony we’ll give out a free raffle ticket.
“The prizes include vouchers for tattoos and men’s pampering days, where they can have their hair done and get a massage and things.
“It’s all about bringing some joy to children at Christmas.”
The raffle winners will be drawn on December 23 and the rocking horse will be donated to the Royal Hospital for Children in Glasgow.
DreamMaker charity founder Les Hoey MBE said: “We will benefit from the sales of the raffle tickets and the children’s hospital will also benefit.
“The rocking horse will be donated to the hospital and they are going to auction it off.”

Hello,
I'm new to oem and I already succeeded to put some measures to emoncms:
http://www.emoncms.org/Phunkafizer/test
It's working perfectly, thanks a lot to the community so far!
Two questions:
- I have a homebrew gasmeter, that reports the absolute impulse count everytime it increases. Because of the radio link sometimes a frame is lost, and sometimes, if there is no count over a certain time the current value is repeated, so here is an example row of data:
5, 6, 8, 9, 10, 11, 13, 13, 13, 14, 15, 17, 0, 0, 1, 2, 4, 4, 5, 7, 7
Aditionally, if the battery has to be replaced, the value starts from 0 again. Every impulse means 1/100 m³
What is the best way to process this data in detail? I want to see the gasusage over the day
- Very similar to that, I have a electrical power meter (EMT7110), which reports the consumed energy in absolute float values:
5.67, 5.68, 5.90, 5.95, 5.97, 6.01, 0.0, 0.01, 0.04
The unit is kWh, also here it goes back to zero when it is unplugged
How to process this one?
At this oppurtinity I'd like to present my own hardware I'm using for receiving radio-thermometers und transmitting gasmeter:
http://www.seegel-systeme.de/index.php?page=rf-soap
Finally here is my current OEM setup:
- Various commercial radio thermometers and hygrometers
- Received by RFSoap module which converts received data to JSON packets, sending them via USB to
- iomega iConnect, on which a small pyhton script is running, sending the data to emoncms
Regards
Stefan
Re: How to process power and gas meter?
Jerome has thought quite a lot about this problem. I'm not sure if he found a perfect solution, but you could try searching through his posts to see what he has written.
Re: How to process power and gas meter?
Indeed, I configured my TX to send the pulses the same way your gasmeter does.
This is ongoing work, and I'm currently stuck with range issues, so I haven't been working on it lately.
I'll propose it for integration when it's all validated. In the meantime, you may want to have a look to:
Current issues:
For this particular issue, I modified emoncms so that when the counter is received with a value equal to the last one, the processing is stopped and the power not calculated. Therefore, when the value is actually increased, the power is computed on a time interval that goes back to the last increment. This is the best we can do with the meter precision.
The issue is with the graphical representation. In practice, you get power profiles (in kW) roughly like this:
12 13 12 1 12 13 12 1
This is for a boiler that goes on for a few minutes every 20 minutes. You get more or less flat peaks, almost like a square wave. And before each peak, you have a low power value that accounts for the energy consumed during the interval between the peaks. This can be real energy (little gas consumption, for cooking or hot water) or an artefact due to the meter precision. In any case, there's nothing we can do about it.
To graphically represent this, I'd like to see a square wave, with a value close to but not 0 between the peaks. (In fact it can never be a perfect 0.) With the current emoncms graphical visualisation, the power points are linked linearly: draw each point, then add a line between them, so as to get a continuous function. But we need a step function: each value is the value of the power for the time passed since last sample. There is no interpolation to make. And if there was, it would be between the points that are at the middle of each segment.
We don't want the visualization to make the graph continuous.
I suppose this would take a new visualization type. I had a quick peek in the code and it wasn't obvious to me how to create one.
Am I making myself clear ? I hope so because this is also a call for help, regarding the visualization need.
I tried to trick the visualization: each time a new power value is computed, before entering it in the database, add another sample with the same value and the time of the last sample, to force the curve to appear as a step function. Obviously, this is a dirty hack. I just wanted to see what it would look like. I couldn't test because of another issue on my setup. This is not pushed on my github branch anyway.

Re: How to process power and gas meter?
Jerome,
I am reading your stuff with great interest, as I will soon be coming across these issues. My next step is to see if I can get a magnetic pulse reading from my meter, so a few steps behind you!
I am hoping that I will be able to power my EmonTx from a mains adapter rather than battery, so I'm not so bothered about saving power.
You may have already thought this through, but instead of using emoncms to calculate power from the number of pulses received (if I understand the sketch correctly), why not calculate the rate of power on the emonTX and send this value?
So transmit from the emonTX every 60 seconds, counting the number of pulses each time, and therefore the kW over this 1 minute period. At low gas consumption figures this will give slightly odd results though?
Chris
Re: How to process power and gas meter?
Some questions on your emonTX sketch (I'm pretty new to coding Arduino sketches);
Line 30: doesn't this code get run first if it is located before the setup? Shouldn't this go after the void loop section?
Line 78: detachInterrupt(1)- doesn't this turn off the interrupt? What is this used for?
Line 85: if(digitalRead(3)==LOW)- what is this if statement for?
Line 91: is the watch dog timer there to count the time between pulses?
Chris
Re: How to process power and gas meter?
Line 30: No. This is the handler interrupt. It is called when a falling edge is received on the interrupt in, thanks to line 69:
(See, "Pulse" is the name of the handler function.)
Line 78: The interrupt is detached for a short amount of time (10ms + computation and RF send) to debounce the signal, otherwise, the Reed switch would generate several interrupts for the same wheel turn. it is then reattached after that, at the beginning of the next loop iteration.
Line 85: This checks that after the 10 ms debounce period, the signal is still low. If not, it was just noise.
Line 91: No. See next paragraph.
I'm using deep sleep mode. If you're on grid, most of the complications in my sketch are useless to you.
In this mode, only the watchdog and the interrupt can wake the TX up. The TX awakes only if a falling edge is received (wheel turn) or the watchdog reaches its end (8s in my case, which is the maximum, but this is not precise, it is rather a minimum).
Because of this, there is no way to compute the power on the TX, because it does not know how much time elapsed since last interrupt: while sleeping, it loses the notion of time. Because of the watchdog precision, and because when the interrupt triggers, we don't know how much time was left in the watchdog (I think, I'm not 100% sure).
You can do the calculations in the TX if you use a lighter sleep mode where you can use a counter. Perhaps is this a better idea. I mean, even on battery, if it does not consume much more, it could be a good idea. I didn't investigate this, thinking if a post-processing is possible, we might as well allow the TX to sleep.
Another option we did not explore is the power computation in the base...
Re: How to process power and gas meter?
Jerome,
Thanks for the detailed reply and explanation. I think it mostly makes sense to me now.
You mention in another thread that you are concerned about the reliability of the wireless transmission of pulses (from the emonTX to the Pi), which is why you are using a counter to send the total number of pulses achieved, then post processing to get the kW over that period. Have I understood correctly?
If I have, I would assume that even if using a power supply for the emonTX, I would have the same issue that occasionally the transmission of a pulse might fail to get to the RPi (wireless transmissions I assume are occasionally a bit dodgy just like my internet at home!)
This isn't a problem with the electrical monitoring using a CT clamp, as if the wireless cuts out for a few seconds it makes no difference, as the TX is broadcasting all the time. But if trying to capture pulses, at low pulse rates this could make a bit more difference. If there was only one pulse per minute, and the wireless transmission failed for some reason, I would get no reading.
Chris
Re: How to process power and gas meter?
Right.
True.
Using the TX on power supply, you could take a different approach, use time knowledge to compute the power in the TX and send the power. In this case, if you miss a frame, it can't be repeated, the value is interpolated, which is generally fine but not great with a low pulse rate. You may be better off using the counter approach as well.

--- layout: simple title: Notes on Stedinger et al. (2008) ---
Stedinger, J. R., Vogel, R. M., Lee, S. U., & Batchelder, R. (2008). Appraisal of the generalized likelihood uncertainty estimation (GLUE) method. Water Resources Research, 44(12).
The generalized likelihood uncertainty estimation (GLUE) method has been in use for watershed models since 1992 following the inaugural paper by Beven and Binley (1992). Thus, there was an early realisation of the need to gauge uncertainty in the predictions made my models within this field and also account for the uncertainty in input data.
Unfortunately, this paper (and others before it) relay that the GLUE methodology may be significantly flawed for this purpose when compared to more contemporary uncertainty processes, although careful application could improve the quality of the estimations when using GLUE.
There is a reference to the Predictions in Ungauged Basins (PUB) initiative of the International Association of Hydrological Sciences, which might be worth looking at. These guys seems to be doing stuff in almost total isolation to the rest of the V&V community, which is kind of interesting.
There were over 500 citations to the Beven and Binley (1992) GLUE paper by the time of writing of this paper, for the reasons given as:
“GLUE’s popularity can be attributed to its simplicity and its applicability to nonlinear systems, including those for which a unique calibration is not apparent.”
Yet, there appear to be severe problems with the methodology:
“Recent evaluations of GLUE by Christensen [2004], Montanari [2005], Mantovan and Todini [2006] and this study clearly demonstrate that prediction limits derived from GLUE can be significantly different from prediction limits derived from correct classical and widely accepted statistical methods.”
The main problem appears to relate to the choice of likelyhood function (to be defined properly later):
“if one wants to correctly understand the information content of the data, one needs to use a likelihood function that correctly represents the statistical sampling distribution of the data.”

This type of test where we test the commit and check the state for an update, could potentially work.
We could also potentially test the Vuex Action itself. Or we could do a feature test on the Order Manager.
Most of these require knowing how to break the test resource so that it throws an error when saving, which I'm not sure how to do.

GPS Setup & Support
|
|
GPS Support: You will find the integrated GPS
support very helpful in many ways and quickly will not want a data log
without it.
Once a GPS is setup in TunerStudio, all the common GPS
fields plus more like HP, Tq and Fuel consumption become fully integrated with your TunerStudio Project
therefore are available for display on gauges and will be captured in
your data logs. These fields include:
- Latitude - GPS Latitude
- Longitude - GPS Longitude
- Heading - GPS Direction you are traveling
- Accuracy - Reported GPS Accuracy based on visibility and quality of your GPS device
- Altitude - GPS Altitude in Meters
- GPS.PositionX - A relative position in meters along the East-West axis from the point in which you first aquired GPS lock.
- GPS.PositionY - A relative position in meters along the East-West axis from the point in which you first aquired GPS lock.
- GPS_Time - Standard GPS Time in ms.
- GPS_Update - Will show as 1 each time the GPS data was updating
for that log record, 0 if it is the same data as the last record.
- MPH - Speed in MPH
- KPH - Speed in KPH
For each of these Fields you will find a Gauge to display the values in
real-time. To change a Gauge to show the GPS field, right click on it
ans select:
Application Gauges --> The gauge of your choice.
Supported GPS Devices - There are many GPS dongles you
can purchase for your Laptop that should be compatible. The typical
integration is a Virtual Com Port over USB or Bluetooth. However, you
will find that as with most things, the quality will vary between
devices, especially when used in a performance environment. The vast
majority of GPS dongles are only capable of 1 update per second. While
this is sufficent for the typical navigation system, it does not
provide the data rate you will want in a performance motor sports
situation or if you want a steady and reliable speedometer. It should
also be noted that some devices take a great deal longer to aquire a
satallite lock and operate with far fewer channels.
For your best experience you will want a GPS capable of 10 Hz, that is
10 updates every second. That means that when you are capturing a data
log, you will have updated GPS data 10 times more often for much finer
grain positioning and speed logging. This also means the speed data can
be used for HP calculation in TunerStudio and MegaLogViewer with far
better results.
Recommended GPS Device:
QStarz BT-Q818XT
- 10 Hz, 66 Channel, 115200 baud that works over USB or Bluetooth so it
can be used on your Android device as well. You can find GPS dongles
for half the price, but they only deliver 1/10th the data.
GPS Setup:
1st consult the documentation that came with your GPS. The documentation will state the supported baud rate.
2nd, connect the GPS dongle to your PC. If it is connected via USB, make sure you have installed any required drivers.
If running Windows, a COM Port will be assigned to your device. It is
sometimes easiest to find out what port was assigned by going into
Windows Device Manager,
expand the node for "Ports (COM &LPT)", there are typically only a
couple devices there, one is most likely the port you use to connect to
your ECU, so in this case, try the other.
- Bluetooth, If you are using bluetooth to connect, you will need to
pair with the GPS, it will then be assigned a COM Port as well.
TunerStudio Setup:
Once you have your GPS device connected to your laptop, you will
connect to it by selecting the proper com port and baud rate in GPS
settings.
In TunerStudio on the Main Menu, select:
Communications --> GPS Configurations
In the GPS Configuration Dialog
- Check "GPS Enabled"
- Select the Connection Type "RS232 Serial Interface"
- Select the COM Port you found in Device Manager
- Set the baud found in your device documentation. For the QStars it is 115200, for most other GPS's it is 9600 baud.
You will then need to restart TunerStudio to have all the GPS channels available.
You can select any of the GPS gauges by right clicking on a gauge and selecting the gauge of choice under the GPS menu

City of Angels
Cast: Meg Ryan -- Maggie Rice Nicolas Cage -- Seth André Braugher – Cassiel Dennis Franz -- Nathan Messinger
Directed by: Brad Silberling Written by: Dana Stevens & Wim Wenders
I didn't come into City of Angels expecting greatness. I've never seen Wim Wenders' Wings of Desire, the classic movie upon which City is loosely based. Then again, I have seen enough stories which are based upon a similar plot device, with The Little Mermaid (both the Disney version and the original folktale) being among them, that I had some high expectations about the possible power such a story of impossible love can hold. Unfortunately, City of Angels ended up fulfilling few of them.
The plot, for those that couldn't tell from the previews, revolves around the angel Seth, played with an almost creepy intensity by Nicolas Cage, who, in the midst of his angelic duties, falls in love with a heart surgeon named Maggie (Meg Ryan in her most endearing performance since When Harry Met Sally). Of course, his being an angel prevents him from doing much about his love except appearing at random times to talk to her, watch her buy groceries, only to disappear in the blink of an eye. Their love must remain unrequited unless Seth decides to make the ultimate sacrifice and become human. Using this framework as a jumping-off point, the movie attempts to veer through some heavy philosophical ruminations on the nature of desire, the joys of being human, and the definition of perfection.
The first half of the movie succeeds on most points. Cage excellently plays the eminently difficult role of an angel who doesn't know feelings so can't really express, preventing the character of Seth from getting boring despite his limited repertoire of intent looks and hang-dog expressions. Unfortunately, Cage takes the intensity too far sometimes, and then Seth comes across as more creepy than sensitive. As Maggie, Ryan manages to be convincing as a heart surgeon who has trouble coming to terms with her having lost a patient on the operating table despite having done everything right. Her beauty, unlike her unbearable cuteness in French Kiss, is mature, intelligent, and winning.
Likewise, some interesting ideas float around at the beginning of the film. When the camera pans through traffic jams and libraries and we get to hear the thoughts of the random people who flash across the screen, the audience experiences a little of what it must be like to be an angel. The beautiful camera work, shooting down onto the hectic world of Los Angeles from the improbable perches of the angels, also gives us a sense of the unique wonder angels feel.
The film begins to lose its way, though, when the focus tightens more and more on Seth and Maggie. The grand, angelic perspective gets lost, except for some idly tossed lines about the incredible beauty of the world through an angel's eyes. The movie devolves into an examination of how Seth can't feel the world or, more importantly, he can't feel Maggie: he can't smell her hair, feel her touch, or taste the pears she eats.
This change in focus attempts to capture the audience in Seth's intense longing, but in doing so, the conflict disappears. If he wants Maggie so badly, then why doesn't her just make the leap and become human? After all, what's so great about being an angel? Sure, you get to sit on Marlboro signs, but what's that compared to getting to be with Meg Ryan?
And from there, once the yearning has been established and the romantic denouement must occur, it's all downhill. The philosophy becomes heavy-handed, the dialogue pedestrian when it tries to be deep, and the plot twists simply attempt to yank a few more tears into the audience's hankie. It's the last thirty minutes of the movie, then, that wrecks the film. I feel like the writer, by pulling out all the melodramatic stops, has robbed me of what could have been a genuinely powerful movie experience on both the romantic and the philosophical level. I came out feeling robbed, seeing so much possibility in a film becoming nothing. I could go on longer, but I don't want to "ruin" the end by revealing any of the cheap plot devices the film relies on.
City of Angels, then, is a paradox. It's a well-acted (particularly look for Dennis Franz cutting against type-casting as a happy-go-lucky fallen angel), well-filmed, and based on a wonderful idea. All these possibilities, though, are what make the film so unredeemable when the closing credits come up.

Heroin |
|
I had used heroin a few times before, and used other opiates like morphine and oxycodone more extensively, but my current spell of heroin use really started on New Years Eve. I injected heroin for the first time that night, and I loved it enough that it scared me. In fact, it scared me so much that I didn't use it again for about a month. It's hard to explain the way that heroin worms into the mind unless one has tried it; it's not that I thought about it constantly throughout that month, but it Was always in the back of my mind.
Finally I gave in - I went downtown and bought a few $20 bags. Then, a few days later, I did it again. And a few days later, again...you get the picture. In a frighteningly short amount of time I was using it 3-5 days out of the week. My friends were very concerned and eventually talked to me about it. I still didn't think I had a problem, but I was sensitive to my friends' concerns because I care about them, so I decided that I would not inject anymore and that I would only use on weekends.
That more or less brings me to the present. It's true that I no longer inject, and that I limit my use to Friday, Saturday, and occasionally Sunday; however, I typically smoke about 1-2 grams in that 2-3 day period - I've found a regular dealer, so I no longer have to risk buying on the street. I use heroin in a way that avoids physical addiction, but I can no longer deny that psychologically I'm hooked. My work week has become an endurance test; at the end of the day on Monday, I think 'I only have to make it through four more days and then I can get high again'.
On Tuesday, it's 'I only have to make it through three more days, and then...', and so forth. I've lost several of my closest friends over this and that's the worst part; these are people that I love with all my heart, and they won't return my calls anymore because I use heroin and, perhaps more importantly, because I refuse to hide it from them like many other users do. I've spent far too much money on heroin in the past month or so, money that should have gone to bills. I take very little pleasure from anything in life except heroin, these days.
I've introduced one of my roommates to heroin; I keep thinking I should feel guilty about that, but I don't. As he put it the day after trying it for the first time, 'Dude, heroin makes you want more heroin'. He now uses on a somewhat regular basis as well.
I should point out again that I'm not a stranger to opiates, and I've been through physical addiction (to morphine) before. Withdrawal is unpleasant, there's no denying that, but at least that I could deal with. Nothing has fixated me psychologically like heroin has, and even though I tell myself I can handle it, sometimes I'm not so sure. I know that I've gotten myself into a bad situation, but I can't imagine just quitting; it seems like the only thing that gets me through the week is knowing that I can get high when it's over.
The simple truth is that I don't want to quit, and I know enough about addiction to know that I'll never break it with that attitude. I guess I've found that heroin is sort of in a middle-ground; it's not the demon that our society makes it out to be, but it's far from harmless.

Good Earth
An augmented-reality app to encourage eco-friendly behavior at the grocery store.
process
secondary research -> fly-on-the-wall observations -> interviews -> storyboarding & speed-dating -> low-fidelity prototyping -> needs validation -> medium-fidelity prototyping -> wizard-of-oz testing -> high-fidelity prototyping -> spec and beta ship

Problem Statement
An individual's carbon footprint is dependent, in large part, on their diet, and the consumption of meat, poultry, and seafood can increase one's footprint manifold. Many environmentally conscious people are aware of this fact, but recent research has found that concern about environmental issues doesn't automatically translate into eco-friendly behavior. As such, a number of other factors, such as time, money, attention, and preference, influence what an individual decides to buy and eat.
Outcome
Good Earth is an augmented-reality application that provides just-in-time information to help environmentally conscious individuals make more responsible purchase decisions at the grocery store. The design of this interface was driven by the insight that people like information, soft nudges, and the freedom to make their own choices.

The help center is designed to allow you to easily provide a list of actions to assist the user. This can either be help with particular things specific to the current page or general help items relevant to all pages. We recommend displaying help center items in a dropdown in the page header, however you are not limited to this.
We provide two ways to utilize the help center functionality. The first is the HelpCenterService
which can
be injected into any component. The service exposes two functions:
registerItem
- This allows you to add a new item to the help center. It expects one argument, an object
following the HelpCenterItem
interface.
unregisterItem
- This allows you to remove an item from the help center. It expects one argument, an
object following the HelpCenterItem
interface.
The service exposes an items
property which is a BehaviorSubject
of HelpCenterItems
.
This can be subscribed to and can be used to show the Help Center items in your UI. It is designed to work well with
the ux-page-header
component icon menus as seen in the example above.
If you wish to associate an element on a page with a help center item you can use the uxHelpCenterItem
directive
which will show the help center item when the element is on the current page and remove it when the user navigates away
from the page.
The uxHelpCenterItem
directive expects a value containing an object that follows the HelpCenterItem
interface.
HelpCenterItem
interface is as follows:
The following code can be used to create the example above:


"If I see Pique focused and in good condition, he'll play"
by BeSoccerErnesto Valverde spoke in a press conference, this time to analyse this weekend's game between Leganes and Barcelona, a game in which Pique and Rakitic are protagonists, by what the coach says: "I have to play the best".
The Barcelona coach made it clear with Pique, whom the Davis Cup organisation may be throwing away: "If I see him focused and in good condition, he will play against Leganes".
"I have spoken with him and I see that he is focused. He has things to do outside of football. When all the players are accused of not knowing how to do anything other than play football, the one who does it is criticised," he added.
About Rakitic, Valverde recognised that "the team is changing a few things". "There are a lot of players in some positions. I don't plan anything as we will see what the moment brings. I have to play the best," he explained.
He was positive about the return of the internationals, as he sees those as "the main ones". "There have been long trips, but not as long as on other occasions," Valverde said.
 "He is in November, like everyone else. Sometimes I don't know what to say. Everyone else is valued on the basis of their success. I see him well and we hope he is better," he said.

On being questioned about Riqui Puig, the Barcelona coach was blunt and explained how the situation is: "We think that he is close to the first team, although there are a lot of players in his position. There are players who are more reluctant to go out because they think that it can cut their progression."
On the other hand, he doesn't trust Leganés, the bottom of the standings. "We're not in a position to think that our opponents are simple," he said, recalling last season's loss to the 'pepinero' team.
His opponent on the bench will be Javier Aguirre, who believes he will achieve "wake up Leganés." "He has a way of reaching the players and bringing out the best in them...," he concluded.

Before proceeding, we offer a few remarks about RAF and its aptness as a figure of merit. First, we acknowledge that the roles of the ocean and land sinks are often left implicit in carbon budget analyses and the text of the Paris Agreement itself leaves ambiguous the definition of ‘net zero emissions' insofar as it does not specify whether sinks need be directly anthropogenic (that is, deliberately created as a result of mitigation policy) or natural (that is, caused inadvertently by the human perturbation of the carbon cycle). We have included natural sinks in this analysis to present a complete accounting of global carbon flows and because the carbon flux from the atmosphere into other parts of the Earth system (that is, biomass, soil and the oceans) will be essential to the magnitude and timing of economic and technological interventions necessary to realize the COP targets.
Second, carbon emissions pathways have an impact on natural sinks through carbon and temperature couplings in the FeliX model, but the sinks do not feed back into anthropogenic emissions from either the energy or LULUCF sectors. Although some mechanisms could complete this feedback loop (for example, permafrost thaw or carbon credits in a hypothetical global cap and trade market), they are not included in this analysis. For this reason, RAF separates the external, prescribed drivers of each scenario (that is, anthropogenic emissions) from the internal, dynamic responses (that is, natural sinks).
With its global scope, this analysis provides a physical science foundation for consideration of the more technically challenging and politically sensitive adaptation and finance goals of the Paris Agreement 1. Similar to the four RCPs established as benchmarks by the IPCC, the scenarios included in this analysis cover a broad range of emissions pathways and can be used to generate insights into the magnitude and timing of the transitions needed to realize the COP emissions and warming targets 6. In particular, our results show that the achievement of the COP emissions target ( RAF≤0.0) before 2100 will also be sufficient to limit warming below 2 °C, even after accounting for the diminishing magnitudes of ocean and land sinks along decarbonizing pathways. This confirms that the COP emissions target should be regarded as the concrete benchmark for Intended Nationally Determined Contributions and subsequent negotiations.
Our analysis extends beyond the IPCC benchmarks in that the RCPs are not fully integrated scenarios of socio-economic, energy and LULUCF emission, and climate projections, but rather internally consistent pathways of atmospheric greenhouse gas concentrations. Indeed, the RCPs are intended as inputs to coupled emissions–carbon cycle–climate models such as FeliX 6. Thus, although the scenarios in this analysis are not exogenously linked with specific RCPs, our reasons for drawing attention to points of comparison between the two sets are twofold: first, comparisons across multiple indicators (that is, emissions, radiative forcing and warming) serve to establish the internal consistency of the FeliX model. Second, comparisons between FeliX scenarios and the RCPs serve to link detailed, particular energy and LULUCF transitions with ‘representative' pathways and mark progress towards the COP target.
The timing of peak energy sector emissions is a critical parameter for climate mitigation strategies. Even before the superposition of CCS, the RE-High scenario achieves much greater progress towards the 2 °C threshold than does the RE-Low scenario, largely because the former pathway accelerates peak emissions by over 30 years relative to the latter ( cf.Table 1). Deeper and more rapid transformations of global agricultural and LULUCF systems can both cut emissions and increase net carbon flux into the land sink, further accelerating peak emissions. Indeed, all of the scenarios examined here project progress towards curbing emissions from land use and land-use change, but none fully exploit the emissions mitigation potential of global agricultural and LULUCF systems 21213.
As a set, our scenarios support broad characterizations of successful decarbonization strategies. Roughly speaking, and based on current technologies, energy sector emissions will need to peak within the next decade. By 2100, the market share of fossil fuels will need to fall to less than a fourth of total primary energy demand to preserve the possibility of meeting the COP targets.
The RE-High pathway (that is, sustained expansion of REs at a minimum of 5% per year) seems at least possible in light of recent trends. Since 1990, low-carbon technologies have grown at an annual rate of 2.2%, slightly outstripping annual growth in the total primary energy supply (1.9% per year) 14. Over the same period, solar and wind energy have grown at 46.6% and 24.8% per year, respectively. However, this standout growth can be attributed to very low initial production rates. Although wind and solar infrastructures have increased by two to three orders of magnitude since 1990, their combined capacity in 2015 equalled roughly 1% of primary energy supply 14.
We also note that, when it is achieved in the
Conversely, if the decarbonization of the energy and LULUCF sectors does not proceed apace, or if nutrient supply limits land sink carbon uptake 1920, then carbon sequestration technology will need to be employed as quickly and as broadly as possible to meet the COP targets. Depending on the economic feasibility of carbon feedstocks for chemical production and chemical energy storage, permanent sequestration of up to an exagram of carbon (1,000 PgC) may be required. This may be technically possible, as global permanent storage capacity has been estimated to range from 135 PgC to as high as 2,700 PgC 21. CCS on such a large scale remains a distant reality, given a current global annual geosequestration rate of only 7.3 MtC 10. On the other hand, this low baseline makes sustained 30–35% year-over-year growth in the geosequestration rate a technologically realistic target, even before economies of scale begin to lower the energy and infrastructure costs of CCS.
Given the scientific community's rapidly evolving understanding of interlinkages among natural and economic systems 13, all mitigation options should be evaluated and it is appropriate to consider the impact of natural sinks on atmospheric carbon and warming pathways. At the same time, the flow of carbon into oceans, plants and soil will affect the functioning of these ecosystems and the services they provide. For example, persistent anthropogenic carbon emissions may affect agricultural yields and thermohaline circulation, as well as the life cycles and long-term stability of forest and marine ecosystems. The consequences of these eventualities, which are potentially as severe as those of global warming, can only be avoided by achieving the goal of strictly carbon-neutral societies as soon as possible.

Moving Posters is an introductionary course into scripting vector graphic images, animations and interactions with the Paper.js framework.
In the workshop we focused on learning approaches to construct, compose, animate and transform 2D graphics, and applied this learned vocabulary to reinterpret preexisting visual works, giving them new expression through the addition of interaction, motion and sound.
Focusing on the format of the poster, each student chose and researched a designer from a propopsed list or of their own choosing, selecting posters and works to base their Paper.js projects on.
Like most graphic design, posters exist to transmit meaning, but they do so by visually condensing a narrative into a clearly confined space, communicating a message in compeling and often surprising ways to reach and speak to a broad audience. Their compositions often suggest movement, sequence, choreography, activity, a fact that was taken one step further in the workshop, by bringing such works further to live through scripting.
The works were allowed to be derivates, hommages, or reinterpretations, but needed to have aspects of animation and interaction, and optionally could be enriched with sound.
The resulting moving posters took the form of many things, holding aspects of:

Gelfand: Chunk 26 - Some Square Roots are Irrational
May 16, 2017
We’re stepping away from quadratics completely for this chunk. Like a dog following an interesting scent, Gelfand is off on what might to the uninitiated seem like a tangent. If you’ve been following along you’ll know that in fact you should in fact be paying more attention. It’s in these digressions that Gelfand typically hides gold which we will rely on later on in our journey.
We’re going to work through the next two problems in our traditional painful levels of detail. While interesting, the thing we are proving - that certain numeric roots are irrational numbers - is not the reason for our travails. The point is that Gelfand’s worked solutions are going to give us more than a few new tools for our problem-solving kitbag. Ones which we’ll need to chunk solidly if we are to progress much further than this.
Proving is Irrational
Gelfand begins hisRemember, there are many solutions to most problems in mathematics. Simply because this is the one Gelfand shows us does not mean it is the only one. We should however assume that (a) it is correct and (b) there are pedagogic reasons for choosing this one. solution to Problem 226 by setting out his stall in a way that should now be familiar.
Laying Out the Stall
First he represents all the elements symbolically:
The then points out that given this, there are four different possibilities in what this gives us. Firstly, that both and are odd, that is even and is odd, that is odd and is even, and that both and are even. He then points out that the last option can actually be expressed in terms of one of the other options if we divided it by a number of times.
For example
We could at this point forge ahead with Gelfand, but let’s hold on a minute. We’re suddenly back in the world of odds and evens. Why?
Remember we’re trying to prove (i.e. demonstrate) that some numbers, for example can’t be represented in the form where and are integers. This means what we’re actually looking for is this
Next up, note the approach Gelfand is taking; he is proving something is the case, by taking all the options to disprove it, and showing that they are not possible.
This is why we have our three options which we prove in turn - Gelfand’s proof-approach is based on an-odd-can’t-be-even and an-even-can’t-be-odd statements of fact. For this to hold water, he needs to consider all the odd/even inputs, to be able to draw general odd/even conclusions.

Representing Odd and Even Symbolically
Now we need to represent odd numbers and even numbers, but we need to use symbols, so that we’re proving things for all odd and all even numbers. We use something that we’ve seen before.
Evens are
and Odds are
In both cases, is any integer including .
Proof Part (a) -
We start where Gelfand starts, by restating our (in)equality in terms of (and also which allows our numerator and denominator to be different numbers.)I’ve flipped the sides of the working that follows. Primarily to keep the reading flow, but also to keep you on your toes mentally. You can thank me later, dear reader.
Then we work this through, starting by squaring both sides
and re-writing the same a little more cleanly
then rearranging
and finally expanding the right hand side
Now we can stop. We have what we need to prove our first inequality.
Considering the left hand side first. It comprises some unknown value which is multiplied by . Clearly for every possible value of , this will be even. So the left hand side will always be even.
Now the right hand side. It comprises two unknown values and which are both multipled by . Clearly these must both be even also, as to multiply something by is the same as multiplying it by and then multiply it by again. But there is something left, a . And we know from previously that odd numbers are obtained by adding to even numbers. This means the right hand side will always be odd.
This is summarised much more pithily by Gelfand
Contradiction: (even number) + 1 = (even number)
Proof Part (b) -
Up next, even divided by odd. We start in an equivalent place to before:
Working this through as before, we again start by squaring both sides
then rearranging (no need for cleaning up this time)
next we expand the right hand side
before expanding the left hand side
and finally dividing both sides by
We can stop here as we have what we need to prove our second inequality.
Again reading from left to right, we start at the left where this half of the (in)equality is exactly the same as the left-hand side in part (a). This means the right hand side will always be odd.
Now the right hand side. It is slightly different from part (a), comprising some unknown value which is multiplied by itself (squared) and then multiplied by . Clearly for every possible value of , this will be even. So the right hand side will always be even.
Yet again we have something which is odd, equalling something which is even, which is not possible. Back to Gelfand again for the punchline:
Contradiction: (even number) + 1 = (even number)
Proof Part (c) -
FInally, odd divided by even. We start yet again in our equivalent place:
Working through again we square both sides
And then multiply both sides by
before finally expanding the right hand side
The result is pretty easy to read now given the practice we’ve had in (a) and (b). The right hand side is clearly always even, while the left hand side can only ever be odd. Back to Gelfand for one last statement:
Contradiction: (even number) = (even number) + 1
In Conclusion
To conclude, we have shown that is always an irrational number, because we have shown that all the ways in which we might represent it as a rational number are impossible.
What about ?
This is Problem 227. You can prove it using exactly the same method Gelfand laid out for us. I’ll not set it out here. I suggest you follow it through yourself however as the doing helps the chunking.
We Cheated?!?
We’re almost done. Hurrah! But Gelfand wants to keep us on our toes. Apparently we (let by him admittedly) cheated. What? How so? It turns out that the Greeks weren’t completely incompetent. When we made up we were in fact admitting defeat. means nothing except as “the positive solution to ”.
It’s worth letting that sink in for a while, just to keep you frosty.
