KAMIKAZE TAXI (1995)
2.5 out of ****
Starring Koji Yashuko, Kazuya Takahashi, Mickey Curtis, Taketoshi Naito, Reiko Kataoka; Written & Directed by Masato Harada; Cinematography by Yoshinao Sakamoto
You know a film is in trouble when it has to explain its premise in an opening caption. The caption at the beginning of KAMIKAZE TAXI tells us three things: 1) There are 150,000 "foreign" labourers in Japan who are in fact emigrés who have returned to their homeland, where they are treated as second-class citizens, 2) There are 90,000 yakuza, and, 3) There are many corrupt politicians. The caption then observes that sometimes the lives of these three groups converge. We need this information because the film is long and unfocused, its polemical intent undermined by its tortuous script. It is part yakuza movie, part buddy movie, part road movie, part social realism, and part a lot of other things. Even with the introductory explanation to guide us, it never coheres.
It seems for quite a while that it will be just a yakuza movie, centring on Tatsuo (Kazuya Takahashi), a second-rate gangster who starts pimping for Senator Domon (Taketoshi Naito) when his predecessor is promoted in the family. Domon is a corrupt, xenophobic misogynist, an aging former kamikaze pilot who seems to represent everything that writer/director Masato Harada dislikes in Japanese society, with good reason. When Domon savagely beats one of the girls Tatsuo sends him, another girl in Tatsuo's employ protests hysterically. She is killed for her trouble by Animaru (Mickey Curtis), a yakuza thug working for Domon.
Tatsuo, who cared for the dead prostitute, is incensed by her murder. When he learns that the beaten girl's silence was bought with a small offering from a huge stash of money in Domon's house, Tatsuo and some of his buddies stage an armed robbery, making off with the Senator's money. Tatsuo, unlike his partners in crime, survives the initial manhunt by the yakuza, and finds himself to be very rich and very high on the yakuza's most wanted list.
The movie thus far is engaged, violent, pointed, darkly humourous, and somewhat routine--it's just a yakuza movie, after all. Then the Japanese-born migrant workers enter the picture. The abrupt shift in direction is no less strange or arbitrary just because it is anticipated by that opening caption. Tatsuo, flush with wealth, hires a cab driven by Kantake, a Japanese-Peruvian recently returned to the country, and tells him to keep the meter running all all the way from Tokyo to Izu, where Tatsuo wants to visit his mother's grave. Cue road movie. Because Kantake is illiterate, Tatsuo has to show him the destination on a map, explaining how to read the words. And so the two men begin to bond. Cue buddy movie.
Once Kantake appears, the emphasis gradually shifts away from Tatsuo, probably because Harada realizes the cab driver is the more intriguing of the two. He is played by the affable Koji Yashuko, currently one of the best-known Japanese actors in the West, after starring in THE EEL and SHALL WE DANCE? and playing a memorable secondary role as the white-suited gangster in TAMPOPO. Yashuko plays Kantake as a quiet-spoken, imperturbable man, burdened by more than his fair share of hardships. A key early scene, a coincidental encounter with an enraged Animaru, establishes Kantake's placid strength, and suggests that he is a man who has seen so much trouble that Tatsuo's concerns seem trivial; a later monologue confirms our initial impression.
The movie nevertheless keeps coming back to Tatsuo and his trivial concerns. To honour a dying friend's request, he resolves to slaughter Domon, Animaru, et al., in a brief blaze of kamikaze glory. Kantake remains stoically by Tatsuo's side, for reasons of his own: Kantake's father, it turns out, was a kamikaze pilot with Domon during World War II, and Kantake has cause to hate the politician for his past deeds. The connection between Domon and Kantake is improbable, but drives the closing sequences, leading to a confrontation which is the film's worst scene.
While Harada's politics are admirably Leftist for the most part, he resorts to the cheap solutions of violence in the finale. Kantake, a serene pacifist when he first appears, becomes a kind of noble urban savage by the end: illiterate, unsophisticated, he obtains justice by following his heart and using his hands, brutally. Harada seems to present this transformation as desirable or at least necessary, contradicting the points he was making earlier.
All told, the film's political thrust seems both confused and, after 140 minutes, belaboured. Harada positions the film rather transparently within political discourse on contemporary Japan. In the opening sequence, for instance, he shows us excerpts from sober talking-head interviews with Japanese-born migrant workers: the tone and method are at odds with the rest of the movie. Elsewhere, there are clips from televised current affairs debates featuring Senator Domon, unsubtly underlining some of the movie's political concerns, which are too broad and complex to be addressed by a genre picture, or, in this case, three genre pictures spliced together. Rather than cramming all these discrete elements into a single film, Harada may have done better to make several shorter, tighter movies--preferably beginning with one about Kantake.

1 How to use R
There are so many ways to analyse data in R. In my opinion the best way is the RStudio. Most R users use R via RStudio. We need both Base R and RStudio, as we did earlier, but if we only start the RStudio, so we can reach all functions of R. RStudio is an integrated development environment (IDE) that provides an interface by adding many convenient features and tools.
Of course, we can use the Base R directly. Usually, this is the only option that is supported by mainframe environment. But, if you have the opportunity, always use RStudio instead of Basic R directly.
Actually, there are several ways to use R, not only Base R and RStudio. The table below summarizes the interfaces in the coloumns and the tools in the rows. There are three different types of interface: Console, Script and Point and click. Interfaces allow the user to interact with R.
Console provides a command-line interface that allows the user
to interact with the computer by typing commands . The computer displays
a prompt (>
), the user types a command and presses Enter or
Return, and gets the result. There are three tools, that
provide console, the Base R Console (it’s the only option in mainframe
environment), RGui in Base R on Windows, and RStudio.
The second interface is the script interface. It gives you an editor window. You can type multiple lines of code into the source editor without having each line evaluated by R. Then, when you’re ready, you can send the instructions to R - in other words, source the script -, and you get the result. You can reach this funcionality in RGui, R Commander and RStudio. Remember, the best way to use R is creating, editing and running scripts in RStudio. This is the best option.
For begginers, the best option would be to use a Point-and-click interface. It has a menu, you can choose menupoints, menuitems, you can get dialog boxes and type in editfields, point on radio buttons and checkboxes. But the knowledge of these systems have limits. You can execute only methods, which you can reach from the menu. The descriptive measures, tables, plots and hypothesis tests, which you can point and click, are part of knowledge of R. The whole knowledge can be reached only from console or script interface. For example I only use jamovi, if I have a simple question and I want to get a quick answer. So I encourage you to install and try jamovi or JASP. These are free and user friendly ways to do statistics. By the way, the tools I listed in this table are all free, except the BlueSky. It is worth installing and trying them.
1.1 Base R
What components were installed with Base R? The Base R consists of three elements. The console for typing commands and getting results, the interpreter for evalueting the commands, and packages for extending R’s knowledge. The interpreter is the heart of the R, all commands will be executed by the interpreter. For the users, for us, the console is the key. Apart from point and click interfaces, we will interact with the console directly or indirectly.
1.1.1 Console of Base R
As we mentioned, the R users meet the console all the time. One main
part of Base R is the console. To start the console, we should type R
(the capital R letter) on all systems, or we can find and click on the R
icon. If you are on Windows, you can launch the R.exe (e.g.
c:\Program Files\R\R-4.0.4\bin\x64\R.exe
).
On the screen above, you can see some information about the R instance. At the bottom of the console window there is a prompt. It consits of a ‘greater than’ sign (symbol) and a space, and of course a cursor where you can type any character. Let’s practise together.
Let’s type any character, delete characters with Delete and Backspace keys, move the cursor with Left arrow and Right arrow keys, insert any character in this position, and navigate the cursor the beginning of the line and the end of the line with the Home and End keys.
If we are ready, we can execute this line, the commad, hitting Enter.
If the command is valid, R or more precisely its interpreter, will execute it, then it returns the result in the console. If the command in not valid, the interpreter returns an error message.
Let’s start with numbers. Type 45 and hit Enter.
45
#> [1] 45
This is a valid command because there is no error message. But the result, the output, is meaningless.
Let’s choose a more complicated expression:
45 + 5
#> [1] 50
Fortyfive plus five sums fifty, so fifty is displayed in the output. The 1 in brackets at the beginning of the output means this is the first line of the output.
<IP_ADDRESS> Console features
Every console has three features, that help us to execute commands.
- History of commands
We can use the Up arrow and Down arrow keys to browse the history of commands, which we typed earlier. When you press the Up arrow, you get the commands you typed earlier at the command line. Of course you can modify them as well. You can hit Enter at any time to run the command that is currently displayed.
- Autocompletion
Pressing TAB key completes the keyword or directory path we were currently typing. Type in
getw
hit TAB and you can see the whole function call, hitting Enter, you can get the working directory.- Continue prompt
Lets’s have a look at a small example. Tpye
45 -
(fortyfive minus) and hit Enter. This is an invalid command, but we can not see any Error message. Instead, a new prompt has appeared, a continuation prompt indicated by a+
(plus) followed by a space character. We can continue typing. The console allows us to complete the command. It’s easy, type for example5
(five), hit Enter. We can get the result. I’ll show you another example. Typegetwd(
without closing parenthesis, hit Enter. We will get the continuation prompt, and typing closing parenthesis we get the working directory. It seems to help us. Continuation prompt seems to be a good thing. But, It is not. It is a really confusing feature. We can easely find ourselves in a never ending story. We can type45 -
, Enter,11 *
, Enter and so on, we keep getting the continuation prompt, and we don’t really know how to complete it in a right way. So, It is very important to leave the continuation prompt as soon as possible. The key is Esc button. Lets’ try this. Type in opening parenthesis and 6 ((6
), hit Enter, and press Esc. We can get back the prompt ‘greater than’ (>
), this is defalt prompt. When you see the plus prompt, continuation prompt, you must press the Esc key.
<IP_ADDRESS> Working directory
In R, we answer the questions we face using functions. So, the
expressions that we type into the command line, usually contains
function calls. So, now, we can request the working directroy. Let’s
type getwd()
to get the interpreter to display our working directory.
getwd()
Working directory is the defalut directory that our command line reaches to access files if we don’t specify a path ourselves. We can specify paths two ways either absolutely from the root directory or relatively starting from our working directory. Beside reaching our histrory in the command line we can also rely on the help of a built-in autocompletion feautre, by pressing TAB key, which completes the keyword or directory path we were currently typing.
For example, let’s type only set
and press TAB and
TAB again to list out all the commands that start with set
.
Press w
and press TAB again, and as you can see the command
line completes our command with a d
to get an existing function name.
All function call requires parentheses after the function name, which
contains additional data for the function which we call arguments.
The setwd()
function has only one required arguments, which is a path
to a directory, which we want to set as our new working directory.
Let’s try calling the setwd()
function, start with the function name,
then the opening parenthesis and inside quote marks we give the
directory’s path.
On Windows, after the first quote mark, type c:/
, which refers the
drive you want to use, and press TAB twice to see all
subdirectories and files on the drive.
From here we can build our path diretory by directory till we reach the directory which we want to set as our working directory. As you can see when jumping from directory into another we mark this jump with the slash character. Instead of writing out the path ourselves we can write the first few characters of directory’s name and we can rely on TAB to autocomplet it for us. Of course with more common directory names we have to be more specific to get the desired autocompletions.
Finally, if we reached our desired new working directory, we can execute the command, by pressing enter, but make sure you have both your opening and closing quote marks and parenthesis. If you had, your command executed successfully thereby changing your working directory, but if you made a mistake either in the formality of the command (called syntactic error) or by giving a path to a directory which dosen’t exsist (called semantic error).
To sum up, to set a working directory in R type:
setwd("Path/To/Your/Workingdirectory")
If you need to check which working directory R thinks it is in:
getwd()
<IP_ADDRESS> Quit the console
In the end, let’s quit the console, by typing and executing the q()
command. Don’t forget the parentheses. We don’t need to save the
workspace. Choose No
.
1.1.2 RGui on Windows
On Windows operating system, Base R has another console which is more advanced. The RGui has a graphical user interface. To start it, find and clilck on the R icon. You should always use the latest version and the 64 bit version.
Let’s start up the afformentioned 64 bit version of it. Above you can see our console wich in functionality is the same as the one we used in Base R recently. We can type any character and press Enter.
If you’d like to change the apperance, or the size of the console, you
can do so in the Edit > GUI preferences
menu in the upper menu bar.
Let’s choose this menu item, and increase the font size to 28 and set
the style to bold. Close this dialog box with OK
button, and you can
see a more readable console window. But as you can see we also have menu
and tool bar.
Let’s try the same basic aritmethic command here. Type 45 + 5
and
press Enter to execute it. And as we can see we get the same
result here.
Let’s try the history with the Up arrow and Down arrow. Navigate the cursor with Left arrow and Right arrow keys, use the Home and End buttons, insert or delete any character and press Enter.
<IP_ADDRESS> Scripting in RGui
RGui has all the functions the Console of Base R had, and also a new
one. We can create script files with which we can use to store commands
in text files. Script files makes easy to store and organize commands.
So let’s click File > New script
which will make us a new script
window where you can edit your script file. We can arrange the Console
and Script windows, click on the Windows > Tile horizontaly
. You
can find the typical face of RGui below.
Let’s write the two commands in to this script file: 45 + 5
and
getwd()
.
Here we only type out command, to actually execute them we will need to transfer them to the console. This window is only a text editor through which we edit our script file. Here we can only use basic notepad like functonalities, so no autocomplition or history.
We can move in a line with the Home and End buttons and through lines with the Page Up and Page Down buttons. With Ctrl+Home we can get to the beginning of the script file and with Ctrl+End we can get to the bottom of it. Of course, this comes handy with much larger script files.
We can mark parts of the text with either holding the Shift key and using the Left-Right-Up-Down arrow keys or using the mouse. And we can use the clipboard as well, Ctrl+C, Ctrl+X and Ctrl+V.
It’s important to know how to actually execute the commands we just wrote into our script file. With Ctrl+R we can execute the line that our cursor is currently at. The process consists of the command getting pulled into the console and then it executing it.
Let’s try it together. Move the cursor into the first line. Click in the first line anywhere. Then press the Ctrl+R. Three things happened at he same time. The first line was pulled into the console, the line was executed, and the cursor jumped down a line. We can repress the Ctrl+R and repeat the whole process for the second line. And so on.
If you have any text selected in your editor prior, pressing
Ctrl+R, then the selected text will be executed. Let’s also
try this. Select only 5 + 5
from the first line, and press
Ctrl+R, and you get 10. Then, select the first two lines and
execute them with Ctrl+R. The interpreter ran both lines. You
can see the result in the console.
As you might have noticed, we have a colored console, the inputs, the commands colored by red, and the outputs, the results colored by blue.
This script files can also contain comments, which is usefull to mark what’s the command’s intention. Which ones again may seem unimportant now, but is really usefull when working with massive script files.
To mark something as a comment use the hash mark (#
) which marks
everything in a line after the hash mark as a comment. It’s good
practice to start your script file with 3 comment lines which containes
the author of the file, the date and a name which gives some kind of
information about what the script does.
# Kálmán Abari
# 2021-03-17
# First script file
Let’s try it together. Navigate the cursor to the first position of the
file, for example pressing the Ctrl+Home. Then type a hash
mark, and your name, Enter. Hash mark, date of today,
Enter, hash mark First script file
, Enter.
If we are ready, we are going to save the script file. It’s important to
save the script file with the file menu’s save option. It’s good
practice to save your work every 15 minutes. It’s important that when we
save our files we give them names that doesn’t contain any special
characters or whitespaces, underscores are accpetable though. Choose a
proper directroy and type in first_script.R
as the filename. Make sure
that our file’s extension should be .R
which means that it contains an
R script file.
With that we covered the basics of the RGui, so we can close it for now, we shouldn’t worry about saving our workspace since we won’t be needing it.
1.2 RStudio
The last tool we will get to know now and will be using for the rest of the book is RStudio. We can also launch it from the start menu. While we had multiple Basic R instances, we only have one RStudio, so it should be easy to find it.
It’s the most advanced interface to use R from the afformentioned ones. And this will be the one that we will mainly use through out the course. Even though we will only use RStudio, it’s important to mention that RStudio relies on Base R to work.
We can easily check which instance of Base R our Rstudio is using. We can see this in the Global options menu under the Tools menu bar option.
Let’s check if it really is using the 64 (sixtyfour) bit version.
Here we can also do other customizations. While we’re here we should also uncheck the Restore .Rdata option and set the Save workspace to Rdata on exit option to never.
Another important one is the Code menu point from the left list. Here under the Saving option we have to set the default text encoding to UTF-8 which is a wildily used and accepted character-code standard.
You can customize to look of your editor under the Apperance option. Here you can change the theme of your editor, which is sets the color palette it uses. I recommend changing it to Tomorrow night bright. Let’s close the settings, by pressing OK, to save the changes we made.
A few words about RStudio. The main area consists of 3 or 4 different panes or windows which all are responsible for a different task. You have 3 panes by basic. The fourth panes you can add is a script file editor, the source pane.
Which you can do by creating a new script file in file – new file – RScript.
You can easily resize the panes with clicking and dragging the vertical or horizontal line between the panes.
A left top, you find your script file editor. At left bottom there’s your console. At the right top is your enviroment. Which containes objects we created and their properties. For now it should be empty. Let’s also watch out for the fact that these panes have multiple tabs on them. This panes also contains the history tab which is another way for us to access our command history.
The right bottom pane’s Files tab lists our working directory and its content. The plots tab houses user created diagrams.
Today we’ll set our focus on the panes on the left.
Let’s put a basic addition, subtraction, multiplication, divison and an extra expression, an exponentiation [eksponesiéisön] (exponent), into our editor on the top left. We use plus, minus, asterisk, slah and double asterisks or hat symbols. So basically double asterisk ** behaves exactly like ^ (hat, caret), these are to-the-power-of , exponent operators.
45 + 5 enter
45 – 5 enter
We can use decimals, for example zero point five, zero point three three.
45 * 0.5 (fortyfive multiplied by zero point five)
45 / 0.33 (fortyfive devided by zero point five)
We need to use the whole number, decimal point and decimal places (tenth, one-tenth, one hundredth, one thousends).
45 ** 3 forty five cubed, forty five to the power of 3
45 ^ 3 forty five cubed again, using hat symbol (usually we type Alt Gr + 3 keys than a space. It is not easy to write out, so we can use the double asterik.)
Let’s set the cursor on the first line a press Ctrl+Enter and see what happens. As in Rgui with Ctrl+R, here in RStudio we use Ctrl+Enter to execute the line our cursor’s at. It does the same thing, copying our command to the console and executing it too. Pressing a new Ctrl+Enter run all lines.
What makes RStudio more appealing? First, our lines are numbered which makes navigation and future bug fixing more easier. Our code is more easily readable because keywords with different functionality get coloured with different colors.
Here we can use autocomplition even in the script editor. Typing getw you can choose the proper function, for example the getwd() function. Press Ctrl+Enter to get the working directory.
When we work with longer script files, we can make bookmarks, which provide easy navigation to specific parts of our code. We can do so, by ending a comment line with 4 dashes.
You can access these bookmarks and jump to the part of the code they mark by clicking this button on the rigth of the source pane, in the top right corner of your script editor.
In R we can reference numbers by the base 10 system, the hexadecimal variation of it. We can use integers, decimals. And we can give numbers in exponential form which is a scientific notation, where the number after ‘e’ gives the powers of ten.
However as of now, the most current version of R is 4.0.4. And so I encourage you to install that version of R, which should be the default version that you find when you go to the R website. So I, in general, I always encourage people to use the latest version of software because those will have the latest features and they will have hopefully fixed bugs that may have been present in earlier version.
You won’t need them.
Learning Objectives
- Be familiar with reasons to use R.
- Understand how R relates to RStudio.
- Be able to navigate the RStudio interface including the Script, Console, Environment, Help, Files, and Plots windows.
- Create an R Project in RStudio.
- Set a “working” directory.
- Send commands from the Script window to the Console in RStudio.
1.3 What is R? What is RStudio?
The term “R” is used to refer to both the programming language to write scripts and the software (“environment”) that interprets the scripts written in R. It is an alternative to statistical packages like SAS, SPSS, or Stata, which lets you perform a wide variety of data analysis, statistics, and visualization.
RStudio is currently a very popular way to not only write your R scripts but also to interact with the R software. To function correctly, RStudio needs R and therefore both need to be installed on your computer.
1.4 Why learn R?
1.4.1 R does not involve lots of pointing and clicking, and that’s a good thing
The learning curve might be steeper than with other software, but with R, the results of your analysis does not rely on remembering a succession of pointing and clicking, but instead on a series of written commands, and that’s a good thing!
Working with scripts makes the steps you used in your analysis clear, and the code you write can be inspected by someone else who can give you feedback and spot mistakes.
Working with scripts forces you to have a deeper understanding of what you are doing, and facilitates your learning and comprehension of the methods you use.
1.4.2 R code is great for reproducibility
Reproducibility is when someone else (including your future self) can obtain the same results from the same dataset when using the same analysis.
R integrates with other tools to generate manuscripts from your code. If you collect more data, or fix a mistake in your dataset, the figures and the statistical tests in your manuscript are updated automatically.
An increasing number of journals and funding agencies expect analyses to be reproducible, so knowing R will give you an edge with these requirements.
1.4.3 R is interdisciplinary and extensible
With 10,000+ packages that can be installed to extend its capabilities, R provides a framework that allows you to combine statistical approaches from many scientific disciplines to best suit the analytical framework you need to analyze your data. For instance, R has packages for image analysis, mapping, time series, text mining, and a lot more.
1.4.4 R works on data of all shapes and sizes
The skills you learn with R scale easily with the size of your dataset. Whether your dataset has hundreds or millions of lines, it won’t make much difference to you.
R is designed for data analysis. It comes with special data structures and data types that make handling of missing data and statistical factors convenient.
R can connect to spreadsheets, databases, and many other data formats, on your computer or on the web.
1.4.5 R produces high-quality graphics
The plotting functionalities in R are endless, and allow you to adjust any aspect of your graph to convey most effectively the message from your data.
1.4.6 R has a large community
Thousands of people use R daily. Many of them are willing to help you through mailing lists and websites such as Stack Overflow.
1.4.7 Not only is R free, but it is also open-source and cross-platform
Anyone can inspect the source code to see how R works. Because of this transparency, there is less chance for mistakes, and if you (or someone else) find some, you can report and fix bugs.
1.5 Knowing your way around RStudio
Let’s start by learning about RStudio, which is an Integrated Development Environment (IDE) for working with R.
The RStudio IDE open-source product is free under the Affero General Public License (AGPL) v3. The RStudio IDE is also available with a commercial license and priority email support from RStudio, Inc.
We will use RStudio IDE to write code, navigate the files on our computer, inspect the variables we are going to create, and visualize the plots we will generate. RStudio can also be used for other things (e.g., version control, developing packages, writing Shiny apps) that we will not cover during the workshop.
RStudio is divided into 4 “Panes”:
- the Source for your scripts and documents (top-left, in the default layout),
- the R Console (bottom-left),
- your Environment/History (top-right), and
- your Files/Plots/Packages/Help/Viewer (bottom-right).
The placement of these panes and their content can be customized (see main Menu, Tools -> Global Options -> Pane Layout). One of the advantages of using RStudio is that all the information you need to write code is available in a single window.
1.6 How to start an R project
It is good practice to keep a set of related data, analyses, and text self-contained in a single folder. When working with R and RStudio you typically want that single top folder to be the folder you are working in. In order to tell R this, you will want to set that folder as your working directory. Whenever you refer to other scripts or data or directories contained within the working directory you can then use relative paths to files that indicate where inside the project a file is located. (That is opposed to absolute paths, which point to where a file is on a specific computer). Having everything contained in a single directory makes it a lot easier to move your project around on your computer and share it with others without worrying about whether or not the underlying scripts will still work.
Whenever you create a project with RStudio it creates a working directory for you and remembers its location (allowing you to quickly navigate to it) and optionally preserves custom settings and open files to make it easier to resume work after a break. Below, we will go through the steps for creating an “R Project” for this workshop.
- Start RStudio
- Under the
File
menu, click onNew project
, chooseNew directory
, thenEmpty project
- As directory (or folder) name enter
r-intro
and create project as subdirecory of your desktop folder:~/Desktop
- Click on
Create project
- Under the
Files
tab on the right of the screen, click onNew Folder
and create a folder nameddata
within your newly created working directory (e.g.,~/r-intro/data
) - On the main menu go to
Files
>New File
>R Script
(or use the shortcutShift
+Cmd
+N
) to open a new file - Save the empty script as
r-intro-script.R
in your working directory.
Your working directory should now look like in Figure 1.9.
If you ever need to set a different working directory you can use the RStudio interface like seen in Figure 1.10.
Alternatively, you can use the shortcut Ctrl + Shift + H to set a working directory in RStudio.
1.6.1 Organizing your working directory
Using a consistent folder structure across your projects will help keep things organized, and will also make it easy to find/file things in the future. This can be especially helpful when you have multiple projects. In general, you may create directories (folders) for scripts, data, and documents.
data/
Use this folder to store your raw data and intermediate datasets you may create for the need of a particular analysis. For the sake of transparency and provenance, you should always keep a copy of your raw data accessible and do as much of your data cleanup and preprocessing programmatically (i.e., with scripts, rather than manually) as possible. Separating raw data from processed data is also a good idea. For example, you could have subfolders in yourdata
directory nameddata/raw/
anddata/processed
that woudl contain the respective raw and processed files. I also like to log my data processing steps in a simple textfile that I keep there as well.documents/
If you are wroking on a paper this would be a place to keep outlines, drafts, and other text.scripts/
This would be the location to keep your R scripts. Again, depending on the complexity, you may want to add subfolders that contain, for example all the plotting scripts, or all the datas cleaning scripts.
You may want additional directories or subdirectories depending on your project needs, but this is a good template to form the backbone of your working directory.
1.7 Interacting with R
The basis of programming is that we write down instructions for the computer to follow, and then we tell the computer to follow those instructions. We write, or code, instructions in R because it is a common language that both the computer and we can understand. We call the instructions commands and we tell the computer to follow the instructions by executing (also called running) those commands.
There are two main ways of interacting with R: by using the console or by using script files (plain text files that contain your code).
1.7.1 RStudio Console and Command Prompt
The console pane in RStudio is the place where commands written in the R language can be typed and executed immediately by the computer. It is also where the results will be shown for commands that have been executed. You can type commands directly into the console and press Enter to execute those commands, but they will be forgotten when you close the session.
If R is ready to accept commands, the R console by default shows a >
prompt. If it receives a command (by typing, copy-pasting or sent from
the script editor using Ctrl Enter), R will try to execute
it, and when ready, will show the results and come back with a new >
prompt to wait for new commands.
If R is still waiting for you to enter more data because it isn’t
complete yet, the console will show a +
prompt. It means that you
haven’t finished entering a complete command. This is because you have
not ‘closed’ a parenthesis or quotation, i.e. you don’t have the same
number of left-parentheses as right-parentheses, or the same number of
opening and closing quotation marks. When this happens, and you thought
you finished typing your command, click inside the console window and
press Esc; this will cancel the incomplete command and return
you to the >
prompt.

Challenge
- Use R to determine what your working directory is.
- Use R to change your working directory to some other place. What do you notice in the RStudio Files window?
- Use RStudio to change back to your previous working directory (r-intro) What do you notice in the RStudio Console?
1.8.3 RStudio Script Editor
Because we want to keep our code and workflow, it is better to type the commands we want in the script editor, and save the script. This way, there is a complete record of what we did, and anyone (including our future selves!) can easily replicate the results on their computer.
Perhaps one of the most important aspects of making your code
comprehensible for others and your future self is adding comments about
why you did something. You can write comments directly in your script,
and tell R not no execute those words simply by putting a hashtag (#
)
before you start typing the comment.
# this is a comment on its on line
getwd() # comments can also go here
One of the first things you will notice is in the R script editor that your code is colored (syntax coloring) which enhances readibility.
Secondly, RStudio allows you to execute commands directly from the
script editor by using the Ctrl + Enter shortcut (on Macs,
Cmd + Enter will work, too). The command on the current line
in the script (indicated by the cursor) or all of the commands in the
currently selected text will be sent to the console and executed when
you press Ctrl + Enter. You can find other keyboard shortcuts
under Tools
> Keyboard Shortcuts Help
(or Alt
+
Shift
+ K
)
At some point in your analysis you may want to check the content of a
variable or the structure of an object, without necessarily keeping a
record of it in your script. You can type these commands and execute
them directly in the console. RStudio provides the Ctrl + 1
and Ctrl
+ 2
shortcuts allow you to jump
between the script and the console panes.
In addition to shortcuts RStudio also provides autocompletion. If you
begin typing a command or the name of a variable or (under certain
conditions) even filenames you have on your latop and thenb hit the
Tab
key, it will make suggestions and relieve you from
typing. More on code completion in RStudio is here:
https://support.rstudio.com/hc/en-us/articles/205273297-Code-Completion
All in all, RStudio is designed to make your coding easier and less error-prone.


To start using the plugin you will need to configure the repository location for the plugin.
<project> ... <pluginRepositories> <pluginRepository> <id>beardedgeeks-releases</id> <url>http://beardedgeeks.googlecode.com/svn/repository/releases</url> </pluginRepository> </pluginRepositories> ... </project>
To configure the merged properties files you have to list them in the plugin configuration. Note that the order of propertiesFile entries matters, the properties of the ones listed below are being overridden by the properties from the ones above.
<project> ... <build> <plugins> <plugin> <groupId>org.beardedgeeks</groupId> <artifactId>maven-merge-properties-plugin</artifactId> <version>0.1.1</version> <configuration> <merges> <merge> <targetFile>${build.outputDirectory}/application.properties</targetFile> <propertiesFiles> <propertiesFile>src/main/config/${property}/application.properties</propertiesFile> <propertiesFile>src/main/config/default/application.properties</propertiesFile> </propertiesFiles> </merge> </merges> </configuration> <executions> <execution> <phase>compile</phase> <goals> <goal>merge</goal> </goals> </execution> </executions> </plugin> </plugins> </build> ... </project>
The example configuration above merges some custom application.properties with a default one so that if a property exists in both properties files, the one from the custom file is used over the from the default application.properties file. The merged properties file is then moved to the project output directory. Also, the plugin execution is bound to compile phase so that it runs automatically on each compilation.
In the example above the ${property} variable is just a plain Maven property. Those can be provided to the plugin using for example build profiles, settings.xml or command-line arguments appending f.ex. -Dproperty=foo to the command. It's also possible to use any environment variable or Java System Property. That enables f.ex. creation of user-specific properties files using the ${user.name} property.

In life, they say you should go with the flow, but sometimes that approach gets you stuck in the current. My summer in Uganda is probably going to be very different than how I am currently envisioning it and that is completely fine.
To avoid drifting through the summer and regretting some aspects later, I figure it might be a good time to set up goals. In class, we talked about SMART goals:
- Specific
- Measurable
- Attainable
- Realistic
- Timely
This seems like a good method to visualize goals. So, after some soul searching (and some procrastination), I've come up with the following goals.
Goal 1: Faithfully execute my project
My project is to investigate the potential of using surface water to irrigate small crops in rural communities. So, my goal is that by the end of the summer, I should be able to tell if it is feasible or not.
Goal 2: Learn Luganda
One of the key hallmarks to a mindful traveler is being respectful of the local culture. A great way to learn a culture is to start with learning the local language. The opportunities in the city open up, people start to open up, and the very semantics of language give insights into the local culture. By the end of the summer, I would like to have learned enough Luganda to take public transport and order food. This will give be my passport into Jinja.
Goal 3: Avoid commoditizing the culture
A Google Images search of Jinja, Uganda quickly shows why the city is called "The Adventure Capital Of Uganda". However, collated amongst the pictures of people white-water rafting and bungee jumping are also photographs of local people who are carrying out daily actions: images of their life. However, the issue is that the influx of tourists (who view the city as their vacation destination) feed the tourism business which can ultimately exploit the history and culture for profit. However, as a traveler, it is really hard to avoid perpetuating the system. My own goal is to buy goods from local vendors as much as possible. This at least puts money in their hands.
Goal 4: Learn how to cook at least two native dishes
This goal accomplishes two purposes. First, it helps me gain a better understanding of the local culture. Second, it might be a good way to better integrate with my host family. Hopefully I can get to know them better by spending some time making a meal with them. If I end up making something edible, then it might be a small token of giving back to my host family.
Goal 5: Make at least one friend in Uganda.
It's always good to make new friends.


Ilhan Omar asks judge to have compassion on man who threatened to shoot her
by Sam DormanRep. Ilhan Omar, D-Minn., publicly requested Tuesday that a federal judge show mercy when sentencing a man who called her a "terrorist" and threatened to shoot her.
"The answer to hate is not more hate; it is compassion." Omar wrote in a letter to Chief U.S. District Judge Frank P. Geraci, Jr., who is set to preside over sentencing for Patrick Carlineo. Carlineo pleaded guilty Monday in Rochester, N.Y., federal court to charges of threatening to assault and murder a U.S. official and being a felon in possession of firearms.
Carlineo, 55, faces up to 10 years in prison, a $250,000 fine or both following his guilty plea. He is scheduled to be sentenced Feb. 14.
"Punishing the defendant with a lengthy prison sentence or a burdensome financial fine would not rehabilitate him," Omar wrote. "It would not repair the harm he has caused. It would only increase his anger and resentment."
PHONED-IN THREAT TO REP. ILHAN OMAR RESULTS IN ARREST OF NY STATE MAN, 55, AUTHORITIES SAY
Prosecutors say Carlineo called Omar's offices on March 21 and told a staff member he would "put a bullet" in Omar.
“Do you work for the Muslim Brotherhood?" Carlineo asked the staffer.  Somebody ought to put a bullet in her skull.
Omar's letter acknowledged the severity of Carlineo's crimes but indicated that his actions were "taught," and requested that he get the opportunity to seek redemption.
TED CRUZ DEFENDS ILHAN OMAR FROM 'REPRENSIBLE DEATH THREATS'
"A punitive approach to criminal justice will not stop criminals like Mr. Carlineo from committing a crime again or prevent others from committing similar acts," she write. "Only restorative justice can do that. He should understand the consequences of his actions, be given the opportunity to make amends and seek redemption.
"If we truly want to prevent crimes like Mr. Carlineo's, we must address the root causes of these crimes," she added. "The desire to commit violence is not inherent in people. People who threaten or commit violence are often themselves the victims of systemic alienation and neglect. They seek violence because they are taught violence. We must address the systemic alienation through community reintegration and social services."
Omar's letter draw praise from Sen. Bernie Sanders, I-Vt., a presidential candidate endorsed by Omar who has decried the "prison-industrial-complex" and called for reform to the system.

"I agree with Representative Ilhan Omar: The answer to hate is not more hate; it is compassion," Sanders tweeted on Tuesday.

Securing An Application¶
Flow provides multiple System categories out of the box, such as AppType, AppTier, and Environment, that are used to quickly group virtual machines. Security policies are applied using these VM groups. Start using these pre-existing categories right away, or add your own categories for custom grouping.
Defining Category Values¶
Prism Central uses categories as metadata to tag VMs to determine how policies will be applied.
In Prism Central, select > Virtual Infrastructure > Categories.
Select the checkbox for AppType and click Actions > Update.
Click the icon beside the last value to add an additional Category value.
Specify Initials-TaskMan as the value name.
Click Save.
Select the checkbox for AppTier and click Actions > Update.
Click the icon beside the last value to add an additional Category value.
Specify Initials-TMWeb as the value name. This category will be applied to the application’s web tier.
Click and specify Initials-TMDB. This category will be applied to the application’s MySQL database.
Click and specify Initials-TMLB. This category will be applied to the application’s HAProxy load balancer.
Click Save.
Creating a Security Policy¶
Nutanix Flow includes a policy-driven security framework that uses a workload-centric approach instead of a network-centric approach. Therefore, it can scrutinize traffic to and from VMs no matter how their network configurations change and where they reside in the data center. The workload-centric, network-agnostic approach also enables the virtualization team to implement these security policies without having to rely on network security teams.
Security policies are applied to categories (a logical grouping of VMs) and not to the VMs themselves. Therefore, it does not matter how many VMs are started up in a given category. Traffic associated with the VMs in a category is secured without administrative intervention, at any scale.
While you wait for the Task Manager application to be deployed from the Calm blueprint, create the security policies that will protect the application.
In Prism Central, select > Policies > Security Policies.
Click Create Security Policy > Secure Applications (App Policy) > Create.
Fill out the following fields:
- Name - Initials-AppTaskMan
- Purpose - Restrict unnecessary access to Task Manager
- Secure this app - AppType: Initials-TaskMan
- Do NOT select Filter the app type by category.
Click Next.
If prompted, click OK, Got it! on the tutorial diagram of the Create App Security Policy wizard.
To allow for more granular configuration of the security policy, click Set rules on App Tiers rather than applying the same rules to all components of the application.
Click + Add Tier.
Select AppTier:Initials-TMLB from the drop down.
Repeat Steps 7-8 for AppTier:Initials-TMWeb and AppTier:Initials-TMDB.
Next you will define the Inbound rules, which control which sources you will allow to communicate with your application. You can allow all inbound traffic, or define whitelisted sources. By default, the security policy is set to deny all incoming traffic.
In this scenario we want to allow inbound TCP traffic on port 80 from all clients on the production network.
Under Inbound, click + Add Source.
Start typing Environment:Production and click Add.
Note
Sources can also be specified by IP or subnet, but Categories allow for greater flexibility as this data can follow a VM regardless of changes to its network location.
To create an inbound rule, select the + icon that appears to the left of AppTier:Initials-TMLB.
Fill out the following fields:
- Protocol - TCP
- Ports - 80
Note
Multiple protocols and ports can be added to a single rule.
Click Save.
Calm could also require access to the VMs for workflows including scaling out, scaling in, or upgrades. Calm communicates with these VMs via SSH, using TCP port 22.
Under Inbound, click + Add Source.
Fill out the following fields:
- Add source by: - Select Subnet/IP
- Specify <IP_ADDRESS>/32
Note
The /32 denotes a single IP as opposed to a subnet range.
Click Add.
Select the + icon that appears to the left of AppTier:Initials-TMLB, specify TCP port 22 and click Save.
Repeat Step 18 for AppTier:Initials-TMWeb and AppTier:Initials-TMDB to allow Calm to communicate with the web tier and database VMs.
By default, the security policy allows the application to send all outbound traffic to any destination. The only outbound communication required for your application is for the database VM to be able to communicate with your DNS server.
Under Outbound, select Whitelist Only from the drop down menu, and click + Add Destination.
Fill out the following fields:
- Add source by: - Select Subnet/IP
- Specify <IP_ADDRESS>/32
Click Add.
Select the + icon that appears to the right of AppTier:Initials-TMDB, specify UDP port 53 and click Save to allow DNS traffic.
Each tier of the application communicates with other tiers and the policy must allow this traffic. Some tiers such as the load balancer and web do not require communication within the same tier.
To define intra-app communication, click Set Rules within App.
Click AppTier:Initials-TMLB and select No to prevent communication between VMs in this tier. There is only a single load balancer VM within the tier.
While AppTier:Initials-TMLB is still selected, click the icon to the right of AppTier:Initials-TMWeb to create a tier to tier rule.
Fill out the following fields to allow communication on TCP port 80 between the load balancer and web tiers:
- Protocol - TCP
- Ports - 80
Click Save.
Click AppTier:Initials-TMWeb and select No to prevent communication between VMs in this tier. While there are multiple web server VMs, they do not need to communicate with each other.
While AppTier:Initials-TMWeb is still selected, click the icon to the right of AppTier:Initials-TMDB to create another tier to tier rule.
Fill out the following fields to allow communication on TCP port 3306 to allow the database connection between the web servers and the MySQL database:
- Protocol - TCP
- Ports - 3306
Click Save.
Click Next to review the security policy.
Click Save and Monitor to save the policy.
Assigning Category Values¶
Note
By this time, your application blueprint should have finished provisioning. If it has not completed, please wait until it has finished to proceed.
You will now apply the previously created categories to the VMs provisioned from your Task Manager blueprint. Flow categories can be assigned as part of a Calm blueprint, but the purpose of this exercise is to understand category assignment to existing virtual machines in an environment.
In Prism Central, select > Virtual Infrastructure > VMs.
Click Filters and search for Initials- to display your virtual machines.
Using the checkboxes, select the 4 VMs associated with the application (HAProxy, MYSQL, WebServer-0, WebServer-1) and select Actions > Manage Categories.
Note
You can also use the Label functionality to make searching for this group of VMs faster in the future.
Specify AppType:Initials-TaskMan in the search bar and click Save icon to bulk assign the category to all 4 VMs.
Select ONLY the Initials-HAProxy VM, select Actions > Manage Categories, specify the AppTier:Initials-TMLB category and click Save.
Repeat Step 5 to assign AppTier:Initials-TMWeb to your web tier VMs.
Repeat Step 5 to assign AppTier:Initials-TMDB to your MySQL VM.
Finally, repeat Step 5 to assign Environment:Dev to your Windows client VM.
Monitoring and Applying a Security Policy¶
Before applying the Flow policy, you will ensure the Task Manager application is working as expected.
Testing the Application¶
From Prism Central > Virtual Infrastructure > VMs, note the IP address of your Initials-HAPROXY-0… and Initials-MYSQL-0… VMs.
Launch the console for your Initials-WinClient-0 VM.
This VM was provisioned as part of the Task Manager application blueprint.
From the Initials-WinClient-0 console open a browser and access http://HAPROXY-VM-IP/.
Verify that the application loads and that tasks can be added and deleted.
Open Command Prompt and run
ping -t MYSQL-VM-IP
to verify connectivity between the client and database. Leave the ping running.Open a second Command Prompt and run
ping -t HAPROXY-VM-IP
to verify connectivity between the client and load balancer. Leave the ping running.
Using Flow Visualization¶
Return to Prism Central and select > Virtual Infrastructure > Policies > Security Policies >Initials-AppTaskMan.
Verify that Environment: Dev appears as an inbound source. The source and line appear in yellow to indicate that traffic has been detected from your client VM.
Mouse over the line connecting Environment: Dev to AppTier:Initials-TMLB to view the protocol and connection information.
Click the yellow flow line to view a graph of connection attempts over the past 24 hours.
Are there any other detected outbound traffic flows? Hover over these connections and determine what ports are in use.
Click Update to edit the policy.
Click Next and wait for the detected traffic flows to populate.
Mouse over the Environment: Dev source that connects to AppTier:Initials-TMLB and click the icon that appears.
Click OK to complete adding the rule.
The Environment: Dev source should now turn blue, indicating that it is part of the policy. Mouse over the flow line and verify that both ICMP (ping traffic) and TCP port 80 appear.
Click Next > Save and Monitor to update the policy.
Applying Flow Policies¶
In order to enforce the policy you have defined, the policy must be applied.
Select Initials-AppTaskMan and click Actions > Apply.
Type APPLY in the confirmation dialogue and click OK to begin blocking traffic.
Return to the Initials-WinClient-0 console.
What happens to the continuous ping traffic from the Windows client to the database server? Is this traffic blocked?
Verify that the Windows Client VM can still access the Task Manager application using the web browser and the load balancer IP address.
Can you still enter new tasks that require communication between the web server and database?


Issue: FORMAT-OP-CReferences: WRITE-CHAR (p384), ~C (p389)
Category: CHANGE/CLARIFICATION
Edit History: 23-Feb-87, Version 1 by Pitman
29-Apr-87, Versions 2,3 by Pitman
5-Jun-87, Version 4 by Masinter (copy-editing)
11-Jun-87, Version 5 release to X3J13
(remove confusing paragraph)
Problem Description:
CLtL is not adequately specific about the function of the format
operation ~C. The description on p389 says that "~C prints the character
in an implementation-dependent abbreviated format. This format should be
culturally compatible with the host environment." This description is
not very useful in practice.
Presumably the authors intended the `cultural compatibility' part to
gloss issues like how the SAIL character set printed, but unfortunately
another completely reasonable (albeit unplanned) interpretation arose:
some implementations have (FORMAT NIL "~C" #\Space) => "Space" rather
than " ".
Since the behavior of ~A is also vague on characters (a separate
proposal will address this), the only way to safely output a literal
character is to WRITE-CHAR; currently, FORMAT does not suffice.
Proposal (FORMAT-OP-C:WRITE-CHAR):
Change the behavior of ~C to say that, when given a character with zero
bits, it will perform the same action as WRITE-CHAR. (This proposal
leaves the behavior of ~C with non-zero bits incompletely specified.)
For example, the description of the ~C format directive on p389 of CLTL
might read:
~C prints the character using WRITE-CHAR if it has zero bits.
Characters with bits are not necessarily printed as WRITE-CHAR
would do, but are displayed in an implementation-dependent
abbreviated format that is culturally compatible with the host
environment.
Test Case:
(EQUAL (FORMAT NIL "~C" #\Space) " ")
Rationale:
This was probably the intent of the Common Lisp designers.
It makes things clear enough that programmers can know what to expect in
the normal case (standard characters with zero bits).
Users can use (FORMAT NIL "~:C" #\Space) to get "Space" if they want it.
It seems as if the implementations which return "Space" treat ~C and ~:C
equivalently or very similarly.
Current Practice:
Implementations are divided. Some implementations have
(FORMAT NIL "~C" #\Space) => "Space".
Others have the same form return " ".
Adoption Cost:
Those implementations which did not already implement ~C as WRITE-CHAR
would require an incompatible change.
Benefits:
User code that uses ~C would have a chance of being portable. As things
stand, users who use ~C can't reliably port their code.
~C and ~:C would perform usefully distinct operations.
Conversion Cost:
Standard ``Query Replace'' technology for finding occurrences of "~C"
and changing them to "~:C" semi-automatically should suffice.
Aesthetics:
Making ~C do something well-defined will probably be perceived as a
simplification.
Discussion:
The cleanup committee generally supports this clarification.
The original version of this proposal (which tried to make WRITE-CHAR
and ~C identical in all cases) prompted the following comment:
"I believe the error in CLtL is that it was not stated explicitly that
the `implementation-dependent abbreviated format' applies only to
characters with non-zero char-bits. Thus instead of removing the
mumbling about cultural compatibility, I suggest simply adding a
sentence saying that ~C is the same as WRITE-CHAR for characters with
zero char-bits. I don't think we want to require ~C and write-char to
do the same thing for characters with bits."

The following was my contribution to an article titled 'The Mars Attraction' by Ms. Geeta Padmanabhan.
In light of the ISRO's Mars Orbiter Mission (MOM), the article looks at the relevance of the efforts by ISRO and NASA towards exploring Mars, the red planet. Though the immediate consequences of mars (or planetary) exploration aren't obvious, it is not an exaggeration to say that repurcussions will be felt in science, finance & industry and overall quality of human life down the line. Many-a-innovation poineered at NASA are currently house hold items or are part of our daily routine and only time will tell how we benifit from ISRO's MOM.
The article was published in the Metroplus section of The Hindu newspaper, available online here
Here's the first draft. Well, ofcourse alien drawings and mars tracks werent mentioned in the article, given their peculiar nature
well, for one, we had to take revenge for the drawings aliens made on earth - the crop circles in south england, south america and so on. And we finally did take revenge last summer when the mars rover, Spirit,
and what reasons will nasa give to offer jobs like this one and this one. Search for "nasa couch potato job" and you'll be amused and amazed at the results! Projects like mars one get mixed reactions, some think it's absurd, some think it will not amount to anything significant.
And finally, to quote Elon Musk, the owner of spaceX, "it would be pretty cool to die on mars, just not on impact". Many more quotes like "The pale blue dot" by Carl Sagan will pop up once man lands on the mars!
On a more serious note, I feel that the humans should land on the mars in the next 15-20 years because this generation, my generation hasn't had a moment like the ones people had in the 1960's. The space race, although it's roots based in bitter rivalry between the us and ussr, bore unexpected fruit like satellites, the space shuttles and what not. And we humans keep looking for reasons to be motivated, to work, to innovate and to do awesome things! this could be a reason for my generation or maybe the next!
Our journey to the moon has given us satellite TV, 3G, the internet, extreme heat resistant ceramic compounds (used on space shuttles), GPS and a gazillion other things. and I can't but wonder what the spill off technologies will be when we try going to mars :)

I just bought and assembled emonGLCD that came with RFM69 transmitter or at least I think so because there is a "RF69" text on the chip and the crystal is SMD. The test sketch works ok but when i try to use a sketch which uses radio the emonGLCD will not power on after sketch upload. I tried with HomeEnergymonitor sketch. I can see from emoncms page that the emonTX sends data. I have a raspberry pi that sends the data to emoncms.
If I use the "#define RF69_COMPAT 0" then it powers up but don't receive anything from emonTX.
If I use the "#define RF69_COMPAT 1" in the sketch then the emonGLCD will not power up after upload.
Re: Problem with emonGLCD
Oh mine...I soldered the RFM69 so that the crystal is to the left as said in the building instructions (there is only mentioned the RF12B). Now it seems that RFM69 should however be soldered in other way round...
Re: Problem with emonGLCD
I managed to de-solder the RFM69 and turned it around. It was a terrible job but now it works! It would have been nice if it was mentioned in the build guide that the RFM69 is assembled differently than RFM12B...
Re: Problem with emonGLCD
Apologies about that, obviously the build guide got forgotten. I've added a warning and instructions, would you be good enough to check and let me know if I've got it right. (I don't have an unassembled GLCD and RFM69 that I can assemble to test and photograph.)
Re: Problem with emonGLCD
Yes, the gold dot goes upper right. I had to give such amount of heat to the pcb that it is a miracle that the poor chip is still alive and one of the soldering pads disintegrated from the main pcb. A little extra work was therefore needed but the best thing is that it works, at least so far...
Re: Problem with emonGLCD
Thanks. I'll use Gimp on a photo and put a RFM69CW on it. Glyn doesn't have a GLCD with the new radio. It's unlikely anyone else will have the problem and the kits are sold out and might not reappear.

Things in WSGI-land have been going well lately, I think. Paste is at 1.0 and doing fine there. Pylons has been gaining in popularity, and it's been doing really well as a traditional and familiar framework on the outside, but with WSGI just under the skin. It's been a compelling introduction to WSGI for many people. Other WSGI-based frameworks have been appearing; I especially like niche frameworks like wsgicollection because they wouldn't be viable frameworks at all if they had to stand on their own. But with WSGI you really can just solve one problem, and not worry about all possible problems.
There's been several recent articles on WSGI. I'm never sure how WSGI should really be presented -- on one level it's an implementation detail of higher-level frameworks. Creating WSGI middleware and dispatchers and whatnot is not terribly advanced, and is genuinely useful even if you aren't inclined to write your own framework from scratch, but it's not a prerequesite to getting things done in WSGI-based environments. But WSGI's success will definitely rely on the community of people that feel comfortable with both the details and the architecture of these systems, so building wide familiarity is important. I've personally come to believe that talking about the architecture of WSGI is more important than the details (which are easy enough to pick up if you are motivated).
I started talking about more standards on Web-SIG. Python is ripe for new standards in lots of areas, and WSGI stacks are among them. The first proposal I introduced just because it seemed like low-hanging fruit, but people seemed to really like it. I guess it's not surprise that low-hanging fruit is usually the best stuff to pick. The proposal describes an environment key (wsgiorg.routing_args) that dispatchers can use to store captured information. In the process we discussed a fairly light process for introducing and accepting proposals, centered now on a wsgi.org page. I also added a bunch of ideas for specs to the bottom of that page; so if you see one you are thinking about yourself, now you know someone else is thinking about it too.
In my own coding, I've been working on WSGIRemote, which is a library to help with making subrequests, both external requests and what should be very fast internal requests (not that I've benchmarked anything). This should make apps using REST internally more manageable -- they should scale down a lot further, requiring less setup and less general overhead. Of course the performance characteristics will change a lot when you actually move services to other processes or servers, but I'm more concerned with manageability at this point. A lot of the tools in Paste (and Paste Deploy) are about managing lots of small pieces without letting that turn into external complexity. One aspect of this is to let applications self-provide the services they need, because most of the time simple internal implementations of an API will be sufficient. Turning a Python library into a service is kind of like adding another level of formality to it; and I think more formality is useful as we try to share pieces of code.
Another earlier-stage project is WSGIFilter, perhaps notably one of the only frameworks for building WSGI middleware. It's not a very big framework, to be sure (it's really just the one file) but it should help implement output filtering in WSGI, which can be really tricky.
WSGI development can seem kind of plodding at times, because we're building up slowly from a low-level foundation. But as the tools emerge they work together really well; I think we're starting to see real returns from that process. If there was a motto for using these WSGI tools together, it might be making large problems smaller -- it's not doing much for you, it's not fancy or magic, things like "convention over configuration" don't even mean anything on this level, it's not code or a framework, it's just an idea and an architecture. Describing what that really means remains a challenge.
I added a couple more specs tonight, for the heck of it:

all the heart, and with all the understanding, and with all the strength, and
to love one's neighbour as oneself, is much more than all whole burnt offerings

Known Issues
This page contains information of known issues when programming WPF Docking.
Windows Forms Interop (WindowsFormsHost)
By design, the WindowsFormsHost is not supported by WPF Docking, due to the restriction of the Framework.
You will receive the error message: "Set focus to DockItem "ItemA" failed. This normally indicates the DockControl is not properly styled." This is because the keyboard focus is set to another HWND (WindowsFormsHost), therefore the IsKeyboardWithin property of the DockItem is false, as explained in the MSDN documentation: "While the HwndHost has keyboard focus, your application will not receive WPF keyboard events and the value of the WPF property IsKeyboardFocusWithin will be false."
Another most significant impact is layout: "HwndHost will appear on top of other WPF elements in the same top-level window." That means the auto-hide window will always draw beneath the WindowsFormsHost.
The design decision is to implement WPF Docking in a pure WPF way, as its name suggested. Otherwise we have to implement DockItem as top level Win32 window, and this will lose many of the WPF benefits and cause endless trouble. If you don't really have the option of not using the WindowsFormsHost, you can use Windows Forms solution DockPanel Suite.
DockControl Must Be Loaded Before Showing DockItem
The DockControl is a window manager, it must be loaded before showing any DockItem, mainly for the following reasons:
- Set keyboard focus correctly;
- To show a floating window, the main window (owner window) needs to be retrieved.
If you attempt to show DockItem before DockControl is loaded (DockControl.IsLoaded="False"), an InvalidOperationException will throw. To avoid the exception, you could:
- Call DockControl.UpdateLayout before calling DockItem.Show;
- Set DockItem.ShowAction and add it to DockControl.Items collection. The DockControl wires Loaded event and do the DockItem.Show for you automatically.

Trump Jr releases provocative book defending father
by AFPNEW YORK: Donald Trump Jr released a book on Tuesday that rails against the left as he admitted he had caught the political bug and may consider running for office in the future.
In ‘Triggered: How the Left Thrives on Hate and Wants to Silence US‘, the president’s son fiercely defends his father and slams mainstream media and political opponents including Hillary Clinton.
“This is the book that the leftist elites don’t want you to read!” screams a blurb on Amazon, adding that “no topic is spared from political correctness.”
Trump Jr dedicates the 300-page part memoir to “deplorables,” a clear dig at Clinton who used the term to describe Trump supporters during the 2016 presidential campaign.
The book quickly rose to third on Amazon’s list of bestselling books after the president on Monday encouraged his 66.5 million Twitter followers to order a copy.
“A great new book that I highly recommend for ALL to read,” Trump tweeted.
Trump Jr, known for his virulent attacks on traditional media including The New York Times and the Washington Post, accuses social networks of trying to censor him and other conservatives.
“This ‘shadow banning’ amounts to a complete suppression of freedom of speech. It can’t be allowed to continue,” he writes in the book, taking aim at Facebook, Instagram and Twitter.
While Ivanka Trump was thought to be the most political of the president’s four adult children owing to her role as a White House adviser, Trump Jr hinted Tuesday that he may be tempted to run one day.
“I don’t rule anything out. Right now I like the campaigning part. I actually enjoy some of that fight,” he told CBS in an interview.
“I like getting out there and being with real people and seeing the difference that my father and his policies are making in their lives.
“I’m interested in winning 2020 for my father right now. We’ll worry about everything else later,” the 41-year-old added.
‘Triggered’ is published by Center Street, a known publisher of conservative books.
Trump Jr was to sign copies at a Barnes and Noble in Manhattan later on Tuesday.
The president has published several books, most famously ‘Trump: The Art of the Deal’ in 1987 which became a New York Times bestseller.
