Colin Kaepernick calls out NFL: 'Stop running from the truth, I'm ready' – video
Colin Kaepernick has said he is ready to play in the NFL after a long awaited tryout at an Atlanta high school on Saturday. ‘I’ve been ready for three years. I’ve been denied for three years,’ said the former San Francisco 49ers quarterback who made headlines by kneeling at games during the US anthem to protest against racial injustice. Kaepernick has said that teams were not willing to sign him to distance themselves from the protests, which US president Trump criticised as unpatriotic and disrespectful


Welcome to my Research Blog
Welcome to my first blog post. Let's get you up to speed regarding my research. After some careful code reorganization and debugging we have completed the visual processing portion of the project. This now gives us more information regarding the environment that the robotic snake is in. We can get exact information that helps us traverse obstacles and engage particular motion primitives.
We will have to rebuild the snake and this time all of the joints will move solely in the x and y plane, however, these small changes will have to be made to the code to adapt to the new dimensions of the snake.
I can illustrate a little bit more here. So the current closed loop process uses object oriented classes that house the information for the snake, the environment, and other things respectively. Therefore when instantiating the Snake model class object we have to pass in the rotational angles, the displacement between each motor joint that moves in the plane we want, and the tailframe in SE2 notation.
%MATLAB code
d = [50,100,150,200,250,300,350];
rot = [0,0,0,0,0,0];
tailframe = SE2([0,0],0);
snk = SnakeModel(d,rot,tailframe);
%These are arbitrary values to illustrate a point
When all of the various classes work together they create this visual interface that models the snake's shape real time using SE2 notation, visual data, and tactile sensing. Below is the result.

@sandbergja I think marking the specs as pending makes sense. Maybe we can also let them know their JS is broken?
We are waiting on the vendor to let us know when these javascripts are ready.
Once their js works, our tests will inform us that we need to remove the pending line.

Spaces in Repast serve two purposes. They can be the basis for "spatial agents" such as the SugarSpace or the InfiniteLifeSpace in the SugarScape and Life demonstration models. And they also function as a collection of agents that define the spatial relationship of agents relative to each other.
Repast offers the following spaces. See the API docs (click the links) for more information. Note that Network spaces are quite different and are covered in the Network Models document.
(Note that in the above, hexagonal refers to the shape of the cells, such that in a hexagonal grid or torus each cell is hexagonal and thus has six neighbors.)
These spaces contain methods for inserting and removing items via the applicable coordinates. They also contain methods for retrieving a list of items in neighboring cells (Von Neumann or Moore neighborhood in the case of non-hexagonal spaces and neighborhood "rings" for hexagonal) as well as for determining the minimum or maximum item in such a neighborhood. What constitutes minimum and maximum can be user-defined.
Using a space as a spatial collection of agents is fairly simple and
is typically a matter of inserting and removing agents from the space,
and perhaps querying the space for an agent's neighbors. The
typical pattern is that all agents in a particular space have an
instance variable reference to that space. So for example, in the
buildModel method in your model, you'd have something like:
Object2DGrid space = new Object2DGrid(spaceWidth, spaceHeight);
for (int i = 0; i < numAgents; i++) {
int x, y;
do {
x = Random.uniform.nextIntFromTo(0, space.getSizeX() - 1);
y = Random.uniform.nextIntFromTo(0, space.getSizeY() - 1);
} while (space.getObjectAt(x, y) != null);
MyAgent agent = new MyAgent(x, y, space);
space.putObjectAt(x, y, agent);
agentList.add(agent);
}
The first line here creates an Object2DGrid space. It then creates some number of agents of MyAgent type. The do loop gets random x and y coordinates and keeps getting new coordinates if the cell in the space at those coordinates is full. The agent is then created, given those coordinates and a reference to the space, and added to the space at those coordinates. (Note that if you were using one of the Multi spaces, you wouldn't need to check if the space cell was occupied as more than one agent can occupy a cell in those spaces.)
Regardless of what sort of space you use, this pattern is typical. The
agent has a reference to the space, and knows its own x and y
coordinates and the space contains the agent. Agent movement is a
matter of changing the agent's internal x and y coordinates,
removing it from its previously occupied cell and adding it to the new
one. For example,
space.putObjectAt(x, y, null);
x = newX;
y = newY;
space.putObjectAt(x, y, this);
As we see here removing an agent from a space cell is accomplished by setting that cell's occupant to null. This code takes place within the agent and thus we use the "this" reference to the current agent to place that agent in the new cell. newX and newY have been set outside our code snippet and no check that the new cell is occupied is done here. Note that the pattern (set to null for remove etc.) for working with Multi spaces is the space, although the exact methods will be different. See the API docs for details.

User Preferences
MiniBatteryLogger lets you to customize about every aspect of the appearance and the behavior of the application.
To show the Preferences window, choose Preferences from the MiniBatteryLogger menu.
The General pane lets you customize the active probe interval, and enable or disable the visualization of the current battery status in the application’s Dock icon and menubar.
The probing interval is the time between two forced polls of the battery data. If set to Never, the application will passively wait for a change in the power properties, resulting in less CPU usage. When you’re on battery you can safely ignore this setting.
Checking the button Launch as Login Item, the application will be automatically launched at startup.
Check Automatically save sessions and Save session on quit to ensure that monitoring data are saved to disk even if you don’t manually save them.
The Chart View pane lets you customize the colors of the charts, enable or disable the amperage graph and the display of event bubbles.
Color is fundamental when dealing with information. If you don’t like the default colors of the chart or you feel more comfortable with a dark background, you can do it from here.
You can also enable or disable the display of those little colored bubbles that mark a power event — oh no, please! They’re so cute!
The Alerts pane lets you customize the threshold under which Low battery and Battery Dying alerts are issued.
To customize the behavior of notifications, refer to the MiniBatteryLogger entry under the Applications list of Growl System Preferences pane.
The Software Update pane lets you enable or disable the automatic update check during the application startup. It also shows the date of the last update check.
Updates are handled by the Sparkle framework .
A convenience button allows you to manually check for updates.
 MiniBatteryLogger communicates with a Shared Battery Data Archive, a huge database of battery statistics on the web, both sending and retrieving data to be used to rate users’ batteries.
You can choose wheter the app should automatically send your battery data to the shared archive, fetch shared data for your laptop model or not (of course, you will always be able to do it manually from the Comparison View.
Additionally, starting from 1.7, MiniBatteryLogger features a network battery data sharing service. This will make computers running MiniBatteryLogger, MiniBatteryStatus or the standalone battd daemon monitorable in an iTunes-like fashion.
Remote batteries will be automatically presented in the left sidebar just like local ones. You will be able to perform on them all the operations you would normally do on a local battery. System administrators will love this feature. Learn how the sharing service works.

Class LogicalStringComparer
Compares two strings for equivalence, ignoring case, in natural numeric order.
Inheritance
Implements
Namespace: Cadru.Collections
Assembly: Cadru.Collections.dll
Syntax
public sealed class LogicalStringComparer : IComparer, IEqualityComparer, IComparer<string>, IEqualityComparer<string>
Remarks
Windows implements natural numeric sorting inside the StrCmpLogicalW function in Shell Lightweight Utility Functions. This function is available on Windows XP or higher.
This implementation is not 100% compatible with StrCmpLogicalW. It gives the same results for the numeric sort, with the exception of strings containing non-alphanumeric ASCII characters. The code relies on the current locale to find the order of the characters.
The code here will order files that start with special characters based on the code table order. Windows Explorer uses another order.

Hollard excludes SAA from insolvency coverage
This comes after a crippling strike at the airline.
by Alexander Winning, ReutersSouth African insurer Hollard excluded struggling state airline South African Airways from its travel supplier insolvency coverage earlier this month, the managing director of the company that administers Hollard Travel Insurance told Reuters.
Read: SAA dropped by leading travel insurer
Uriah Jansen, managing director of Oojah Travel Protection, said Hollard took the decision after a crippling strike started at SAA on November 15 and the airline warned it might not be able to pay salaries.
Another large South African travel insurer, Travel Insurance Consultants, has also stopped covering tickets issued by SAA against insolvency.

Marks: grade tracking
Marks is a simple grade tracking application specifically developed to help teachers keep track of grades. The two main aspects driving the development of the application are user data storage and simplicity. Firstly, data is stored locally (on the user's device) to add an extra layer of security for students' data. Secondly, the application has to be easy to use.
Features:
- Add, update and delete for Classes, Students, Subjects, Exams, Grades
- View and download grade charts
- Use the calendar feature to create and save class schedules and events


sha256 - SHA256 Message-Digest Algorithm
This package provides an implementation in Tcl of the SHA256 and SHA224 message-digest algorithms as specified by FIPS PUB 180-1 (1). These algorithms take a message and generates a 256-bit (224-bit) digest from the input. The SHA2 algorithms are related to the SHA1 algorithm.
This package also includes support for creating keyed message-digests using the HMAC algorithm from RFC 2104 (3) with SHA256 as the message-digest.
The command takes a message and returns the SHA256 digest of this message as a hexadecimal string. You may request the result as binary data by giving -bin.
The data to be hashed can be specified either as a string argument to the sha256 command, or as a filename or a pre-opened channel. If the -filename argument is given then the file is opened, the data read and hashed and the file is closed. If the -channel argument is given then data is read from the channel until the end of file. The channel is not closed. NOTE use of the channel or filename options results in the internal use of vwait. To avoid nested event loops in Tk or tclhttpd applications you should use the incremental programming API (see below).
Only one of -file, -channel or string should be given.
If the string to hash can be mistaken for an option (leading dash "-"), use the option -- before it to terminate option processing and force interpretation as a string.
Like ::sha2::sha256, except that the SHA224 digest is returned.
Calculate an Hashed Message Authentication digest (HMAC) using the SHA256 digest algorithm. HMACs are described in RFC 2104 (3) and provide an SHA256 digest that includes a key. All options other than -key are as for the ::sha2::sha256 command.
If the string to hash can be mistaken for an option (leading dash "-"), use the option -- before it to terminate option processing and force interpretation as a string.
For the programmer, the SHA256 hash can be viewed as a bucket into which one pours data. When you have finished, you extract a value that is derived from the data that was poured into the bucket. The programming interface to the SHA256 hash operates on a token (equivalent to the bucket). You call SHA256Init to obtain a token and then call SHA256Update as many times as required to add data to the hash. To release any resources and obtain the hash value, you then call SHA256Final. An equivalent set of functions gives you a keyed digest (HMAC).
If you have critcl and have built the tcllibc package then the implementation of the hashing function will be performed by compiled code. Failing that there is a pure-tcl equivalent. The programming interface remains the same in all cases.
Begins a new SHA256/SHA224 hash. Returns a token ID that must be used for the remaining functions.
Add data to the hash identified by token. Calling SHA256Update $token "abcd" is equivalent to calling SHA256Update $token "ab" followed by SHA256Update $token "cb". See EXAMPLES. Note that this command is used for both SHA256 and SHA224. Only the initialization and finalization commands of both hashes differ.
Returns the hash value and releases any resources held by this token. Once this command completes the token will be invalid. The result is a binary string of 32/28 bytes representing the 256/224 bit SHA256 / SHA224 digest value.
This is equivalent to the ::sha2::SHA256Init command except that it requires the key that will be included in the HMAC.
These commands are identical to the SHA256 equivalent commands.

At the conclusion of the term of the reverse mortgage loan contract, some or all of the equity in the property that is the subject of the reverse mortgage no longer belongs to the person and the person may need to sell or transfer the property to repay the proceeds of the reverse mortgage from the proceeds of the sale or transfer or the person must otherwise repay the reverse mortgage with interest from the person's other assets.
The lender will charge an origination fee, a mortgage insurance premium, closing costs or servicing fees for the reverse mortgage, all or any of which the lender will add to the balance of the reverse mortgage loan.
The balance of the reverse mortgage loan grows over time and the lender charges interest on the outstanding loan balance.
The person retains title to the property that is the subject of the reverse mortgage until the person sells or transfers the property and is therefore responsible for paying property taxes, insurance, maintenance and related taxes. Failing to pay these amounts may cause the reverse mortgage loan to become due immediately and may subject the property to a tax lien or other encumbrance or to possible foreclosure.
Interest on a reverse mortgage is not deductible from the person's income tax return until the person repays all or part of the reverse mortgage loan.


Duration
15 minutes
Lab goals
The primary goal of this lab is to display a collection of data in a ListView
. You will also
get some experience with the ArrayAdapter
class which is useful to display string data and
for prototyping when you need to build a list quickly. Use the following high level steps to complete the
exercise and refer to the complete step-by-step instructions below to provide any necessary details you
need or to check your code.
You will create an app that displays a list of the Xamarin University instructors. Each instructor has a
name, a photo, a specialty, and a biography. An Instructor
class and code to generate a
collection of instructor objects has been provided.
Since you will be using ArrayAdapter
, you will be limited to displaying a single
string for each instructor (subsequent parts of this session will use a custom adapter to
remove this restriction). The starter code concatenates the instructor's name and their specialty
to form the string to display.
The user interface will have a single layout with a ListView
as its only child element.
Your code-behind will create an ArrayAdapter
using the sample instructor data and
load it into the Adapter
property of the ListView
. The finished project
will look like this:
Required assets
The provided Exercise 1 folder contains resources that you will need in order to complete the lab, please make sure you have this folder before you begin.
- Assets/Instructor.cs contains a simple class to represent an instructor.
- Assets/InstructorData.cs creates and populates a list of instructor objects.
- The Completed folder contains a completed version of the lab you can use to check your work.
Steps
Below are the step-by-step instructions to implement the exercise.
Create the project
- Open Visual Studio.
- Create a new Android Application. Name it XamarinUniversity.
Remove unneeded template code
-
Open Resources/layout/Main.axml. Remove the
Button
from the layout. -
Open MainActivity.cs. Remove the following lines (if present):
int count = 1; ... Button button = FindViewById<Button>(Resource.Id.MyButton); button.Click += delegate { button.Text = string.Format("{0} clicks!", count++); };
Add the starter code
- Add the files Instructor.cs and InstructorData.cs from the Exercise 1 folder to the project.
-
Open Instructor.cs. Note the override of
ToString
that concatenates the name and specialty. -
Open InstructorData.cs. Notice the static constructor that creates a list of
Instructor
objects sorted by name. The actual creation of the objects is done in theAddInstructors
method. In a later part of this session, we will need a larger set of data to test scrolling and we will add multiple calls toAddInstructors
to simulate a large data set. Finally, note the static property namedInstructors
that returns the list ofInstructor
objects.
Display the list of instructors
- Open Resources/layout/Main.axml.
-
Add a
ListView
to theLinearLayout
. Give it an id of instructorListView so it can be accessed from code-behind. Set itslayout_width
tomatch_parent
and itslayout_height
towrap_content
. - Open MainActivity.cs.
-
Use
FindViewById
to get a reference to the instructorListView
. -
Create an
ArrayAdapter<Instructor>
. You need to pass three things to the constructor:-
A context - you can use your Activity object here, i.e.
this
. -
The id of the layout file to use for the row. Use the predefined Android layout file
Android.Resource.Layout.SimpleListItem1
. - The collection of instructors.
-
A context - you can use your Activity object here, i.e.
-
Load the
ArrayAdapter
into theAdapter
property of theListView
. - Run the app to test your work. You should see each instructor's name and specialty displayed in a list.
ListView
.
This UI pattern is so common that there is a helper class named ListActivity
that builds this UI for you and removes the need to use an .axml file.
Summary
In this lab, you built an Android application that usedListView
, ArrayAdapter
, and
a predefined Android layout file to display a collection. ArrayAdapter
let you do this
quickly and with very little code but without much opportunity to provide custom UI formatting.

--- layout: post title: "Composition Root Reuse" description: "A Composition Root is application-specific. It makes no sense to reuse it across code bases." date: 2015-01-06 10:40 UTC tags: [Software Design, Dependency Injection] --- {% include JB/setup %}
{{ page.description }}
At regular intervals, I get questions about how to reuse Composition Roots. The short answer is: you don't.
Since it appears to be a Frequently Asked Question, it seems that a more detailed answer is warranted.
A Composition Root is application-specific; it's what defines a single application. After having written nice, decoupled code throughout your code base, the Composition Root is where you finally couple everything, from data access to (user) interfaces.
Here's a simplified example:
public class CompositionRoot : IHttpControllerActivator { public IHttpController Create( HttpRequestMessage request, HttpControllerDescriptor controllerDescriptor, Type controllerType) { if(controllerType == typeof(ReservationsController)) { var ctx = new ReservationsContext(); var repository = new SqlReservationRepository(ctx); request.RegisterForDispose(ctx); request.RegisterForDispose(repository); return new ReservationsController( new ApiValidator(), repository, new MaîtreD(10), new ReservationMapper()); } // Handle more controller types here... throw new ArgumentException( "Unknown Controller type: " + controllerType, "controllerType"); } }
This is an excerpt of a Composition Root for an ASP.NET Web API service, but the hosting framework isn't particularly important. What's important is that this piece of code pulls in objects from all over an application's code base in order to compose the application.
The ReservationsContext class derives from DbContext; an instance of it is injected into a SqlReservationRepository object. From this, it's clear that this application uses SQL Server for it data persistence. This decision is hard-coded into the Composition Root. You can't change this unless you recompile the Composition Root.
At another boundary of this hexagonal/onion/whatever architecture is a ReservationsController, which derives from ApiController. From this, it's clear that this application is a REST API that uses ASP.NET Web API for its implementation. This decision, too, is hard-coded into the Composition Root.
From this, it should be clear that the Composition Root is what defines the application. It combines all the loosely coupled components into an application: software that can be executed in an OS process.
It makes no more sense to attempt to reuse a Composition Root than it does attempting to 'reuse' an application.
The above example uses Pure DI in order to explain how a Composition Root is equivalent to an application definition. What about DI Container-based Composition Roots, then?
It's essentially the same story, but with a twist. Imagine that you want to use Castle Windsor to compose your Web API; I've already previously explained how to do that, but here's the IHttpControllerActivator implementation repeated:
public class WindsorCompositionRoot : IHttpControllerActivator { private readonly IWindsorContainer container; public WindsorCompositionRoot(IWindsorContainer container) { this.container = container; } public IHttpController Create( HttpRequestMessage request, HttpControllerDescriptor controllerDescriptor, Type controllerType) { var controller = (IHttpController)this.container.Resolve(controllerType); request.RegisterForDispose( new Release( () => this.container.Release(controller))); return controller; } private class Release : IDisposable { private readonly Action release; public Release(Action release) { this.release = release; } public void Dispose() { this.release(); } } }
Indeed, there's no application-specific code there; this class is completely reusable. However, this reusability is accomplished because the container is injected into the object. The container itself must be configured in order to work, and configuration code is just as application-specific as the above Pure DI example.
Thus, with a DI Container, you may be able to decouple and reuse the part of the Composition Root that performs the run-time composition. However, the design-time composition is where you put the configuration code that select which concrete types should be used in which cases. This is the part that specifies the application, and that's not reusable.
Composition Roots aren't reusable.
Sometimes, you might be building a suite of applications that share a substantial subset of dependencies. Imagine, for example, that you're building a REST API and a batch job that together solve a business problem. The Domain Model and the Data Access Layer may be shared between these two applications, but the boundary isn't. The batch job isn't going to need any Controllers, and the REST API isn't going to need whatever is going to kick off the batch job (e.g. a scheduler). These two applications may have a lot in common, but they're still different. Thus, they can't share a Composition Root.
What about the DRY principle, then?
Different applications have differing Composition Roots. Even if they start with substantial amounts of duplicated Composition Root code, in my experience, the 'common' code tends to diverge the more the applications are allowed to evolve. That duplication may be accidental, and attempting to eliminate it may increase coupling. It's better to understand why you want to avoid duplication in the first place.
When it comes to Composition Roots, duplication tends to be accidental. Composition Roots aren't reusable.
Comments
In the example where the domain layer and the data access layer are shared between applications, it really depends whether they will have a future need to be wired differently according to the application.
If that's not the case, you could argue that there's no need for two components either.
One solution would be to use a Facade which internally wires them up and exposes it as a single interface. This allows for reuse of the domain and the DAL as a single component, opaque to the client.
Kenneth, thank you for writing. If you create a Facade that internally wires up a Domain Model and DAL, you've created a tightly coupled bundle. What if you later discover that you need to instrument your DAL? You can't do that if you prematurely compose object graphs.
Clearly, there are disadvantages to doing such a thing. What are the advantages?
Dear Mark,
Thank you for another excellent post.
Some of the composition roots I wrote became really large, too, especially the more complex the application got. In these cases I often introduced factories and builders that created parts of the final object graph and the imperative statements in the composition root just wired these subgraphs together. And this leads me to my actual question:
What do you think about pushing these factories and builders to a library so that they can be reused by different composition roots? This would result in much less code that wires the object graph. I know that abstract factories belong to the client, but one could provide Simple Factories / Factory Methods or, even better I think, the Builder Pattern is predestined for these situations, because it provides default dependencies that can be exchanged before the Build method is called.
If I think about automated tests, I can see that the concept I just described is already in use: every test has an arrange phase which in my opinion is the composition root for the test. To share arrange code between tests, one can use e.g. builders or fixture objects (or of course AutoFixture ;-) ). This reduces the code needed for the arrange phase and improves readability.
What is your opinion on pushing Simple Factories / Builders to a reusable library?
With regards,
Kenny
In the production environment, the service is deployed as a Windows Service, but for easier testing and development, we also have a console application that hosts the same service. Both entry points are basically the same composition root and should use the same components. We want to share the composition root, because otherwise when a component needs a new dependency and a constructor parameter is added, we'd have to change the same code in two different places.
Kenny, Daniel, thank you for writing. In an attempt to answer your questions, I wrote a completely new blog post on the subject; I hope it answers some of your questions, although I suppose you aren't going to like the answer.
If you truly have a big Composition Root, it may be one of the cases where you should consider adopting a DI Container with a convention-based configuration.
Another option is to make your 'boundary library' (e.g. your UI, or your RESTful endpoints) a library in itself, and host that library in various contexts. The Composition Root resides in that boundary library, so various hosts can 'reuse' it, as they reuse the entire application. You can see an example of this in my Outside-In Test-Driven Development Pluralsight course.
Dear Mark, thank you for writing the other blog post. Now I finally have time to answer.
I think in our specific situation there is a subtle but important difference: Rather than reusing a composition root between two libraries, we essentially have two different ways of hosting the same library (and thus composition root). One is used primarily during development, while the other is used in production, but essentially they are (and always will be) the same thing. So in my opinion it would even be dangerous to not use the same composition root here, as it would just add a source of errors if you change the dependency graph setup in one project but forget to do so in the other.
But I guess this is what you meant with creating a boundary library, isn't it?
Daniel, if I understand you correctly, that's indeed the same technique that I demonstrate in my Outside-In Test-Driven Development Pluralsight course. Although it may only be me splitting hairs, I don't consider that as reusing the Composition Root as much as it's deploying the same application to two different hosts; one of the hosts just happens to be a test harnes :)

/* In-browser code editing made bearable */
CodeMirror is a JavaScript library that can be used to create a relatively pleasant editor interface for code-like content ― computer programs, HTML markup, and similar. If a parser has been written for the language you are editing (see below for a list of supported languages), the code will be coloured, and the editor will help you with indentation.
The following browsers are able to run CodeMirror:
I am not actively testing against every new browser release, and vendors have a habit of introducing bugs all the time, so I am relying on the community to tell me when something breaks. See below for information on how to contact me.
All of CodeMirror is released under a zlib-style license. To get it, you can download the latest release or the current development snapshot as zip files. To create a custom minified script file, you can use the compression API.
We use git for version control. The main repository can be fetched in this way:
git clone http://marijnhaverbeke.nl/git/codemirror
CodeMirror can also be found on GitHub: http://github.com/marijnh/CodeMirror. If you plan to hack on the code and contribute patches, the best way to do it is to create a GitHub fork, and send pull requests.
The manual is your first stop for learning how to use this library. It starts with a quick explanation of how to use the editor, and then describes all of the (many) options and methods that CodeMirror exposes.
For those who want to learn more about the code, this document about CodeMirror's architecture will be useful. The source code itself is, for the most part, also very well commented.
There is a Google group (a sort of mailing list/newsgroup thing) for discussion and news related to CodeMirror. Please check the FAQ before asking a question. You can also e-mail me directly: Marijn Haverbeke.

I am a 15 year old male currently living in Arizona. I was put on Zoloft in April 2001 for OCD. One day before school I took about 5 50 mg tablets before leaving my house. By the time I had arrived at school about forty five minutes later I felt a rush of energy go through me. I felt a gain of self confidence enter my mind as I walked to my locker and began talking to some of the kids around. I remember myself feeling like I was doing everything at a million miles per hour and the rest of the world was standing still. Before class even started it felt like the whole day had gone by. Right before classes this energy was replaced by nausea, but it was calmed down by walking around and I felt my heart beating rapidly. I was in a sense of panic and the nausea got worse so I made it to the bathroom and vomited in the toilet. Once I had thrown up, the nausea was relieved, but my heart was still beating rapidly as if I had taken amphetamines.
In the middle of my first class a sense of euphoria came over me and it was like I didnt care anymore. It made me feel like my life was worth something and the gain of self confidence began to get stronger again. I went through just about all of my classes like this and I hardly remember anything about them because I began to think about what was going on in my life and the problems didnt seem important anymore.
After school, I went home on the bus and I noticed that I had a headache so I went home and tried to rest, but I couldnt because I still felt like I was tweaking. The next day when I woke up from what little sleep I had from waking up multiple times in the middle of the night and not being able to fall back asleep for an hour, the headache had gotten worse. At about noon I finally crashed from the speedy feeling I had and rested for about an hour. My heart was still beating quickly however and my headache was almost a migraine and when I woke up my nose began to bleed and I realized that the zoloft increased my blood pressure. This slowly wore down and I was feeling normal by the next day.
I felt that my overall experience on Zoloft was very unique. It almost combined the effects of amphetamines and alcohol. However, I do not recommend that anyone take more than 150 mg. I had a friend who got the same effects as I did without the nausea and high blood pressure at 100 mg and he weighs in at 244 pounds. I do think tolerance has an effect though because before that I had taken 100 mg without any unsual effect before since I was on the medication.

The ggh4x package is a ggplot2 extension package. It provides some utility functions that don’t entirely fit within the ‘grammar of graphics’ concept —they can be a bit hacky— but can nonetheless be useful in tweaking your ggplots. Examples include adjusting the sizes of facets, mapping multiple aesthetics to colours and specifying individual scales for facets. Besides this, it is also a small collection of geoms, facets, positions, guides and stats.
You can install the development version from GitHub with:
# install.packages("devtools")
devtools::install_github("teunbrand/ggh4x")
There are a few topics explored in the package’s vignettes with examples. Links to these topics are below.

I would like to mention that there are also packages that do some similar things to what this package does. facetscales also has a facet function wherein scales can set per row/colum. The egg package can also set panel sizes. The lemon package also has options to tweak position axes. The relayer and ggnewscale packages also allow multiple colour scales in the same plot.
Historically, many of these functions come from the ggnomics package, but have been moved here as a package independent of Bioconductor infrastructure.


Hi,i m try upload test sketch on my GLCD (without any emonTX station and sensors) and get error
Template_Example.ino: In function 'void loop()':
Template_Example:49: error: 'draw_power_page' was not declared in this scope
Template_Example:52: error: 'draw_temperature_time_footer' was not declared in this scope

Arduino libraries exist in lib folder. But i can upload one of the examples GLCM_SSM. Arduino IDE 1.0.5 also i tryed 1.5.4 no results.Thanks
Re: cant upload sketch on EmonGLCD
When opening say the HomeEnergyMonitor.ino example it should load the other sub files at the same time (icons.ino and templates.ino) The error's you see there are related to the sketch needing the functions that are in the templates.ino page.
Do you have icons.ino and templates.ino in the same folder as in the standard emonglcd examples folder?
Re: cant upload sketch on EmonGLCD
Hi,Trystan. Yes, icons on it.Files exist. I try compile HomeEnergyMonitor.ino -its OK, but after i click compile and upload button in IDE and get error
avrdude: stk500_getsync(): not in sync: resp=0x00
Now i try reinstall IDE, drivers
No result!!! After reinstall IDE apper message about low memory
<tag> Sketch uses 24 344 bytes (75%) of program storage space. Maximum is 32 256 bytes.
Global variables use 1 645 bytes (80%) of dynamic memory, leaving 403 bytes for local variables. Maximum is 2 048 bytes.

Question: could i insert another ATMega chip with UNO bootloader and try again or it uncompatible ?
Thanks
Re: cant upload sketch on EmonGLCD
Can the emonGLCD run a standard example sketch such as blink.ino?
If it can, that might be a useful stage to try - no libraries required.
Re: cant upload sketch on EmonGLCD
Thaks for reply.Standart Blink.ino sketch dont uploading either with stk500 error message. I remove ATmega chip and repalace with another from emonTX PCB, try install IDE on another PC and still get 500 error code.Please help, i use arduino USBtoSerial board to connect emons product with PC.
Re: cant upload sketch on EmonGLCD
After some experiments i saw that driver is OK cause i can upload blink etc on arduino UNO (another plate) and its work. Now i measure voltage between GRN and PWR and it become 5V , but it should be 3.3V isnt it? (it was 3.3 then i constructed it as describe in tutorial). Whats should i do? THX

For the impatient
The command line used by the QEMU Eclipse plug-in to start a debug session looks like this:
$ qemu-system-gnuarmeclipse --verbose --verbose --board STM32F4-Discovery \
--mcu STM32F407VG --gdb tcp::1234 -d unimp,guest_errors \
--semihosting-config enable=on,target=native \
--semihosting-cmdline blinky
A typical emulation session started outside Eclipse looks like this:
$ qemu-system-gnuarmeclipse --verbose --verbose --board STM32F4-Discovery \
--mcu STM32F407VG -d unimp,guest_errors \
--nographic --image test.elf \
--semihosting-config enable=on,target=native \
--semihosting-cmdline test 1 2 3
Command line options
QEMU has lots, lots of options. The official QEMU documentation (available in the distribution doc
folder) is the authoritative source for information about them.
Unfortunately most of these options were designed for the larger versions of QEMU, intended to emulate Linux systems, and are of little use for Cortex-M emulation.
The GNU MCU Eclipse QEMU redefines some of these general options, or adds new ones, and generally uses only a small subset of the available options.
The common ones are presented below.
board
A string that defines the name of the board to be emulated:
--board STM32F4-Discovery
To get a list of supported boards, use ?
or help
:
--board ?
mcu
Each board has a MCU type, hardcoded in the board definitions.
However it is possible to pretend the board has a different MCU, by explicitly specifying a MCU name:
--mcu STM32F407VG
To get a list of supported MCUs, use ?
or help
:
--mcu ?
image
The emulator currently does not preserve a persistent state of the flash memory between runs; instead, it starts with an empty flash and preloads it with the content available in an ELF file.
For debug sessions, this can be done via the GDB protocol. For standalone sessions, QEMU needs to know the name of the ELF file:
--image blinky.elf
gdb
When used with a debugger, QEMU must implement the GDB server protocol, for the GDB client to be able to connect to it.
The default QEMU port is 1234
; the option to start QEMU in server mode and listen on the TCP port 1234 is:
--gdb tcp::1234
When in GDB server mode, it is no longer required to specify the ELF image, since it will be loaded by the GDB client, as in any usual debug session, which rewrites the MCU flash memory.
nographic
By default, the GNU MCU Eclipse QEMU will try to start in graphical mode, by displaying an image of the emulated board and one or more animated LEDs.
For running unit tests this is generally not needed, and QEMU can be started with graphics support disabled:
--nographic
verbose
By default, qemu
is very quiet, it barely complains for errors.
To make it minimally social, add one --verbose
, and it’ll tell what is going on:
xPack 64-bit QEMU emulator version 2.8.0-9 (v2.8.0-7-3-ge221f2b601-dirty)

Adding one more --verbose
will make QEMU extra verbose and it’ll display details about the board hardware configuration and the memory sections loaded by GDB:

d
By default QEMU is not only quite, but also secretive, even when it detects problems during emulation, it does not report them.
To make QEMU inform the user about these problems, the -d
options can be used to enable some debug options.
There are many such options available, but the ones the plug-in uses are:
-d unimp,guest_errors
semihosting-config
QEMU fully implements the ARM semihosting protocol. To enable it, use the following complicated option:
--semihosting-config enable=on,target=native
semihosting-cmdline
To fully use semihosting, it should also be possible to pass command line options to the emulated application.
Any number of options can be used, but generally it is recommended to keep this to a minimum, since most embedded applications will allocate only a small buffer to receive the semihosting options, and if this buffer is overflown, no options will be passed at all.
This option must be the last one, and all following options will be passed to the application:
--semihosting-cmdline test 1 2 3
The first option will be passed as argv[0], so it generally should reflect the application name. The following options will be passed as argv[1] … argv[n-1], without special processing.
exit() code
When started in semihosting mode, if the application’s main()
routine returns 0 and the application is a fully semihosted one, QEMU will also return 0 to its parent process. This is particularly useful when running unit tests, since 0 means the test was successful. Unfortunately the semihosting specs do not allow to pass the full exit code, so for all other returned values, QEMU will return 1, which can be used as an indication of a failed test.
This is not really a big limitation, since unit tests can be configured to write an XML file with the detailed test results, so the binary exit code is enough to represent the pass/fail, and Continuous Integration systems will generally process the XML file for details.
Fully semihosted applications
When using QEMU for running unit tests, and expecting the exit code to reflect the test result, it is mandatory for the application to be compiled and linked as a fully semihosted application, in other words all system calls to be implemented using the semihosting interface. For the projects created by the Eclipse Embedded CDT wizards, this is achieved by defining OS_USE_SEMIHOSTING
; outside Eclipse Embedded CDT it depends on the libraries used, for example newlib can be configured for semihosting by adding --specs=rdimon.specs
to the linker options.
