Hi
This has now happened twice. I have 433Mhz remotes that we use to switch off lights and devices on standby. Recently this stopped working. At the same time all emoncms (on 433Mhz) devices in the same building failed. The rest of our emoncms setup which is in a different building with the server continued to work normally. I don't know whether the emontx stops transmitting or the nanodeRF stops receiving. In both cases after about 5 days it all started working again. I had just ordered a receiver so I could build a monitor to see if I could see the signals. Has any one experienced something similar or have any idea what could cause this? The last time it occurred was around 23:00 on the 3rd of July and from memory we may have had a storm that night.
Regards
Ian
Re: Why should all 433Mhz devices fail
Hi Ian,
The 433 Mhz frequency used by OEM lies in a portion of the radio spectrum allocated to Industrial, Scientific, and Medical devices, as well as an Amateur Radio band.
Given the radio modules used in the OEM system don't have a great deal of selectivity, i.e. the ability to reject unwanted signals, it sounds like what you're seeing might be the result of interference from something operating at, or near 433 Mhz, located in the general vicinity of your equipment.
Regards,
Bill
Re: Why should all 433Mhz devices fail
MartinR modified an emonGLCD as a RF
spectrum analysersignal strength meter, if I remember correctly [I didn't!]. It would be worth looking up that post.Re: Why should all 433Mhz devices fail

Hi Robert,
Is this post you're referring to? http://openenergymonitor.org/emon/node/2395
Martin called it a RF Signal Strength meter, but it looks like it could be useful for troubleshooting Ian's issue.
and here's another one showing a transmission clash, I think this is OOK from my weather station...
Re: Why should all 433Mhz devices fail
You're right Bill, I ruminated on it a while then it took me more of a while to find it! I'd edited my post before I'd seen yours! But it still wasn't bad for 2 years ago.
Re: Why should all 433Mhz devices fail
I think the only reason I remembered it was I'd made a comment on Martin's post.
Hopefully, it'll help Ian resolve his issue
Re: Why should all 433Mhz devices fail
I have converted a RFM2Pi firmware to use the RFM69CW RSSI value to plot a scope like trace over a serial port, similar idea to Robin's waveform tools, seen as a vertical realtime trace in the arduino IDE (or minicom etc).
The "trace_mode" can be selected as a function on a fully working sketch, so when you suspect there is something adrift you can just dial in and take peak without changing sketches. It isn't as tidy as Martin's glcd method and he uses a 10bit adc attached to the rf signal rather than reading an existing value of only 100 steps, but it doesn't require a hw mod or glcd and it seems to work ok.
The sample rate is variable from 0.1 secs to 2.5secs in 0.1s steps, quiet_mode, group, promiscuous mode and frequency adjustments work as usual to help filter/tune the issue.
I will tidy it up and post it over the weekend.
Paul
Re: Why should all 433Mhz devices fail
Many thanks.
I have an emonGLCD so I will build the the signal strength meter ready to monitor if it happens again. I can only think something is operating periodically that is interfering with the signal. This is strange as we have no immediate neighbours. We are one of the few residents surrounded by holiday homes which are seldom if ever occupied. The only things that the owners leave on are the boilers. We have keys so I can take my signal strength meter into their property and see if the signal changes.
Regards
Ian
Re: Why should all 433Mhz devices fail
I performed the emonGLCD mod and have used it for troubleshooting and antenna testing - it's great!
In my neighborhood there is a TON of 433mhz traffic going on. We have smart power and water meters... the water meters are the main offender, blasting out 20 second long strings at very high power. I have my emonTX in the same room as the RFMPi receiver, but the smart meters mounted outdoors on the surrounding homes block any communication during their bursts. Fortunately they are not too frequent.
I also discovered interference in other places where you wouldn't expect it. For example, I took the emonGLCD to a farm out in the middle of nowhere. I was surprised to see there was a lot of traffic as well. In that case I tracked it down to their Davis weather station which was fully optioned with multiple soil moisture sensors, leaf wetness sensors, and the irrigation system remote which was also interfering.

Re: Why should all 433Mhz devices fail
I know you are going to go the glcd route, but just as a follow up to my previous post above, I have now posted the code for Adding a trace_mode to rfm2pi firmware as promised.

Struggling Blazers pick up Carmelo Anthony - report
Los Angeles - Carmelo Anthony, who hasn't played in over a year since being dumped by the Houston Rockets, has signed a contract with the last place Portland Trail Blazers, US media reported Thursday.
The 35-year-old Anthony last played on November 8, 2018 when he shot just one of 11 from the floor and scored two points in the Rockets' 98-80 loss to Oklahoma City.
Anthony started just two games and played parts of eight other contests with Houston before being cut and eventually traded to the Chicago Bulls in January 2019.
Anthony never played a game for the Bulls, who waived him through the league a month later.
The struggling Trail Blazers have lost two straight and are in last place in the Pacific Division with a 4-8 record.
This would be the Anthony's fifth team since 2016 as he tries to rekindle some of the form that earned him the league scoring title in 2012-13 and won him three Olympic gold medals with the United States men's team.
Anthony has 25,551 career points, a figure that trails only LeBron James' 32,806 among active players.
His career average of 24.0 points per game also sits 19th in NBA history. Only James (27.1), Kevin Durant (27.0) and James Harden (24.6) have better career scoring averages among active players.
The Blazers have a field-goal percentage of .441 this season which is 23rd best in the league.
Portland's next game is Saturday at San Antonio, the start of a six-game road trip.

Has anyone done any inroads in creating or implementing Enterprise Single Sign-on solutions of any kind? I'm specifically talking about both handling user and account management across heterogenous environments in a unified way, plus having credentials management and aliasing to support single sign-on across applications (such as the case of application X calling application Y calling application Z on behalf of user A).
This is a topic I've recently gotten interested on based on some of the difficulties I've seen on some of our clients, and would love to hear any stories "from the trenches" :)

BQN expressions are the part of syntax that describes computations to perform. Programs are mainly made up of expressions with a little organizing material like blocks and namespaces around them. This page explains how functions, modifiers, and assignment combine with their inputs. It doesn't describe constant and array literals, which each form a single subject for grammatical purposes.
The first tutorial also covers how to build and read BQN expressions.
BQN expressions consist of subjects, functions, and modifiers arranged in sequence, with parentheses to group parts into subexpressions. Assignment arrows ←
and ↩
can also be present and mostly act like functions. Functions can be applied to subjects or grouped into trains, while modifiers can be applied to subjects or functions. The most important kinds of application are:
| left | main | right | output | name | binding |
|---|---|---|---|---|---|
w? |
F |
x |
Subject | Function | RtL, looser |
F? |
G |
H |
Function | Train | |
F |
_m |
Function | 1-Modifier | LtR, tighter | |
F |
_c_ |
G |
Function | 2-Modifier |
The four roles (subject, function, two kinds of modifier) describe expressions, not values. When an expression is evaluated, the value's type doesn't have to correspond to its role, and can even change from one evaluation to another. An expression's role is determined entirely by its source code, so it's fixed.
In the table, ?
marks an optional left argument. If there isn't a value in that position, or it's Nothing (·
), the middle function will be called with only one argument.
If you're comfortable reading BNF and want to understand things in more detail than described below, you might check the grammar specification as well.
This issue is approached from a different angle in Context free grammar.
In APL, the way one part of an expression interacts with others is determined by its value. That means that to parse an expression, in general you would have to evaluate that part, get a value, check its type, and then figure out how it fits in with the rest of the expression. This is a lot of work. BQN changes things so that you can determine how to parse an expression just by looking at its source code. But because it still needs to support expressions that can evaluate to more than one possible type, BQN has to introduce a new and independent concept, called syntactic role, in order to support APL-like expressions.
Syntactic role is a property of an expression, not its value. To describe it in terms of English grammar, you might say "I like BQN", using "BQN" as an object, or "BQN scares me", using it as a subject. BQN itself isn't a subject or object, it's a programming language. Similarly you might write F g
, placing f
in a function role to apply it to g
, or G f
to use f
as an argument. Maybe even in the same program, although it's unlikely.
Below, the function {𝕎𝕩}
treats its left argument 𝕎
as a function and its right argument 𝕩
as a subject. With a list of functions, we can make a table of the square and square root of a few numbers:
⟨×˜,√⟩ {𝕎𝕩}⌜ 1‿4‿9 ┌─ ╵ 1 16 81 1 2 3 ┘
The four roles are subject, function, 1-modifier, and 2-modifier, as shown in the table below. Each type has an associated role (non-operation types all correspond to subjects), and the value of an expression will often have a type that fits the role, but it doesn't have to.
| BQN | Names | Primitives |
|---|---|---|
| Subject | lowerCase |
Literals |
| Function | UpperCase |
+-×÷⋆√⌊⌈|¬∧∨ … |
| 1-modifier | _leading |
˙˜˘¨⌜⁼´˝` |
| 2-modifier | _both_ |

Primitive tokens, since they have a fixed value, always have a role that matches their type. They're functions by default, as the modifiers have glyphs that fit specific patterns. 1-modifiers have superscript glyphs, and 2-modifiers have glyphs with an unbroken circle—that is, one without a line through it, excluding functions ⌽
and ⍉
.
Variable names (including namespace fields) can be written in any case and with underscores added, and these changes don't affect what identifier the name refers to. ab
, aB
, AB
, and _a_B_
are all the same variable. However, the spelling—specifically the first and last characters—determine the variable's role. A lowercase first letter indicates a subject, and an uppercase first letter makes it a function. A leading underscore (regardless of the following character) indicates a 1-modifier, and both leading and trailing underscores makes a 2-modifier.
Besides these, character, string, and array literals always have a subject role, and the role of a block is determined by its type, which depends either on the header it has or which special variables it uses. If headerless, a block is a subject if it has no special names, but a 𝕨
or 𝕩
makes it at least a function, an 𝔽
makes it a 1- or 2-modifier, and a 𝔾
always makes it a 2-modifier.
The role of a compound expression, formed by applying an operation to some inputs, depends on the operation applied. This system is covered in the remaining sections below.
As in most programming languages, parentheses ()
are for grouping. The code inside a balanced set of parentheses is a single expression, which produces one value to be used by the expression that contains it—for example, in (2×3)+4
, 2×3
is a subexpression evaluating to 6
, so that larger expression is equivalent to 6+4
. The syntactic role of a set of parentheses is also the same as that of the expression inside.
The character ·
is called Nothing. While it can be easier to think of it as a value, it can't be passed around in variables, and so can also be interpreted as an element of syntax. The special name 𝕨
also functions as Nothing if the block that contains it is called with one argument (the uppercase spelling 𝕎
doesn't, but instead immediately causes an error). Both ·
and 𝕨
have a subject role.
The following rules apply to Nothing:
For example, the expression (F 2 G ·) H I j
is equivalent to H I j
. But functions and arguments that will be discarded by the second rule are still evaluated, so that for example (a+↩1) F ·
increments a
when run.
Nothing can only be used as an argument to a function, or the left argument in a train (it can't be the right—a train ends with a function by definition). In another position where a subject could appear, like as an operand or in a list, it causes an error: either at compile time, for ·
, or when the function is called with no left argument, for 𝕨
.
Here is a table of the function and modifier application rules:
| left | main | right | output | name |
|---|---|---|---|---|
F |
x |
Subject | Monadic function | |
w |
F |
x |
Subject | Dyadic function |
F |
G |
Function | 2-train | |
F* |
G |
H |
Function | 3-train |
F* |
_m |
Function | 1-Modifier | |
F* |
_c_ |
G* |
Function | 2-Modifier |
An asterisk *
indicates that a subject can also be used. Since the role doesn't exist after parsing, function and subject spellings are indistinguishable in these positions. Modifier applications bind more tightly than functions, and associate left-to-right while functions associate right-to-left.
Expressions may also include assignment, which is written with ←
or ⇐
to define (similar to "declare" in many other languages) a variable and ↩
to change its definition. Assignment has a left-hand side (name
below) which is usually a variable name, and a right-hand side (↕4
) which can be any expression. The roles of the two sides have to match. It sets the value of the variable to be the result of the expression.
name ← ↕4 name ⟨ 0 1 2 3 ⟩
A variable can only be defined once within a scope, and can only be changed if it has already been defined. However, it can be shadowed, meaning that an inner scope can define it even if it has a definition in an outer scope already.
↗x←1 ⋄ {x←2 ⋄ x↩3 ⋄ x} 3 x 1
Assignment can be used inline in an expression, and its result is always the new value of the assignment target. Function or modifier assignment must be parenthesized, while subject assignment doesn't have to be: in a subject expression, assignment arrows have the same precedence as functions.
↗2×a←(Neg←-)3 ¯6 a ¯3
The modification arrow ↩
can also be used to update the value of a variable by applying a function. This meaning applies only when there is no expression to the right of ↩
or that expression has a subject role, and there's a function to the left of ↩
(in terms of precedence this function is like an operand—a train must be parenthesized). The two forms of modified assignment are shown below along with equivalent expansions.
| Syntax | Meaning |
|---|---|
a F↩ |
a ↩ F a |
a F↩ b |
a ↩ a F b |
The left hand side of assignment in a subject expression can be compound, so that assigned values are extracted from lists or namespaces. This is called a destructuring assignment. The most common case is list destructuring: the left hand side's written as a list, and the value on the right has to be a list of the same length. Assignments are made element-wise, and the elements can destructure things further.
↗⟨q‿r,s⟩ ← ⟨"qr",↕4⟩ ⟨ "qr" ⟨ 0 1 2 3 ⟩ ⟩ r 'r' s ⟨ 0 1 2 3 ⟩
Array destructuring using array notation []
is also possible: it's equivalent to splitting the right-hand side with <˘
and then applying list destructuring.
[t,u] ← ↕2‿3 ┌─ ╵ ⟨ 0 0 ⟩ ⟨ 0 1 ⟩ ⟨ 0 2 ⟩ ⟨ 1 0 ⟩ ⟨ 1 1 ⟩ ⟨ 1 2 ⟩ ┘ u ⟨ ⟨ 1 0 ⟩ ⟨ 1 1 ⟩ ⟨ 1 2 ⟩ ⟩
Namespace destructuring uses an overlapping syntax, fully described in its own section. The left hand side is a list of names, or aliases to⇐from
.
q‿r ↩ {q⇐2+r⇐0.5} ⋄ q 2.5
With destructuring, you might want to discard some values from the right hand side rather than assign them any name. There's special syntax for this: use Nothing (·
) for a placeholder non-name in the appropriate position, like ·‿y‿· ← list
.
· ← 6 # Doesn't do anything 6
The double arrow ⇐
exports variables from a block or program, causing the result to be a namespace. It can be used either in place of normal definition ←
, or as a stand-alone statement with nothing to the right; in either case all the variables to its left are exported. An example with both uses, as well as namespace destructuring that uses ⇐
to define variable aliases, is shown below.
⟨alias⇐a, b⟩ ← { b‿c⇐ a⇐2 c←÷b←1+a }

You can retrieve the source code through Git by using the command:
git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg
FFmpeg has always been a very experimental and developer-driven project. It is a key component in many multimedia projects and has new features added constantly. Development branch snapshots work really well 99% of the time so people are not afraid to use them.
Git Repositories
Since FFmpeg is developed with Git, multiple repositories from developers and groups of developers are available.
| Clone URL | Description |
|---|---|
| Main FFmpeg Git repository | |
| https://git.ffmpeg.org/ffmpeg-web | Main ffmpeg.org website repository |

Releases
Approximately every 3 months the FFmpeg project makes a new major release. Between major releases point releases will appear that add important bug fixes but no new features. Note that these releases are intended for distributors and system integrators. Users that wish to compile from source themselves are strongly encouraged to consider using the development branch (see above), this is the only version on which FFmpeg developers actively work. The release branches only cherry pick selected changes from the development branch, which therefore receives much more and much faster bug fixes such as additional features and security patches.

cv_scrnp.Rd
This function computes K-fold cross-validated estimates of estimates of cross-validated sensitivity-constrained rate of negative prediction (SCRNP). This quantity can be interpreted as the rate of negative classification for a fixed constraint on the sensitivity of a prediction algorithm. Thus, if an algorithm has a high SCRNP, it will also have a high positive predictive value.

To estimate the SCRNP using K-fold cross-validation is problematic. If
data are partitioned into K distinct groups, depending on the sample size
and choice of K, the validation sample may be quite small. In order to estimate
SCRNP, we require estimation of a quantile of the predictor's distribution. More extreme
quantiles (which correspond to high sensitivity constraints) are difficult to estimate
using few observations. Here, we estimate relevant nuisance parameters in the training sample and use
the validation sample to perform some form of bias correction -- either through
cross-validated targeted minimum loss-based estimation, estimating equations,
or one-step estimation. When aggressive learning algorithms are applied, it is
necessary to use an additional layer of cross-validation in the training sample
to estimate the nuisance parameters. This is controlled via the nested_cv
option below.
# simulate data n <- 200 p <- 10 X <- data.frame(matrix(rnorm(n*p), nrow = n, ncol = p)) Y <- rbinom(n, 1, plogis(X[,1] + X[,10])) # estimate cv scrnp of logistic regression scrnp_ests <- cv_scrnp(Y = Y, X = X, K = 5, nested_cv = FALSE, learner = "glm_wrapper") # estimate cv scrnp of random forest with nested # cross-validation for nuisance parameter estimationscrnp_ests <- cv_scrnp(Y = Y, X = X, K = 5, nested_cv = TRUE, learner = "randomforest_wrapper")


public class PreviewMaker
extends java.lang.Object
Creates small 'preview' images of each frame in the animation
To create the small frame previews used in the SuiteDirector
this class needs to get the colours on each frame (stored as RGB and
characters) and put them into an Image
form for display.
It does this using BufferedImage, WritableRaster
and
Graphics2D
.

public PreviewMaker(BoardModel passedBoard)
The constructor has a BoardModel
passed as a parameter with
which to get the correct sizings of the grid
.
A ColourHolder
is also stored here so this class can search
for the colours that will be the same as those in
SuiteDirector
and correspond to the same RBG/character
values.
The board
is stored and grid
size is held in
two fields for height and width (rows and columns).
passedBoard
- a copy of the current state of the board
in order
to get all of the grid
s and make preview images
of them.protected final javax.swing.JLabel generateImage(int num)
Creates the JLabel
and ImageIcon
that will be
put added to the frame preview panel in SuiteDirector
.
SuiteDirector
calls this method with the parameter for which
frame number to create a preview of. colorSquares
holds all
of the RBG values of each colour from the grid
.
The method goes through all of the colours held in the grid
array by searching using the char
representation. The
MyColor
found is stored and it's RGB values are extracted
and added to the colorSquares
ArrayList.
num
- An integer to represent which grid
should be made
into a preview.JLabel
containing the preview
ImageIcon
.protected final javax.swing.JLabel createImageLabel(int[] passedSquareHolder)
Creates a BufferedImage
, which is passed to another method
for resizing, and returns the JLabel
to
generateImage()
.
The method creates a new BufferedImage, based on the size of the
grid
, with RGB colour type. From this, a
WritableRaster
is created/extracted and it's data is set
with the image width/height and using the RGB values saved into the array
squareHolder
.
This new Image
is sent to be resized in
resizeImage
with new sizes and the result is returned as a
JLabel
.
passedSquareHolder
- An array of all of the RGB values of each colour in the
grid
in left-right order of display.JLabel
holding the created and resized image.protected final java.awt.image.BufferedImage resizeImage(java.awt.Image image, int newWidth, int newHeight)
Takes an Image
, sent as an ImageIcon
, and
resizes it.
Starts by taking the image and new dimensions for it and create a
BufferedImage
based on these new dimensions. Graphics are
extracted from the BufferedImage
using the in-built method,
and from this we create a new Graphics2D
of the image.
We draw this image, resizing it with the new dimensions and then
dispose()
of the Graphics2D
and return the new
BufferedImage
to be set on the JLabel
.
image
- The image to be resized.newWidth
- the new width of the image.newHeight
- the new height of the image.
