2. Single Body¶
Note
This page is rather detailed, it tries to follow the lectures of Prof. Patrick Wensing closely. It does not look like the best approach: takes a long time to produce and gets crowded. I want this notes to be brief and to the point.
Next chapters are more refined. Instead of using this page following is strongly recommended Primer on Spatial Dynamics.
2.1. Spatial Velocity¶
Spatial velocity is defined as a Vector Field. It is different then the conventional sense of velocity. Conventional velocity is defined as a single vector.
A good way to think of the spatial velocity is to think that the body extends to infinity in all directions. All points on body will have a certain velocity in the conventional sense. All these conventional velocity vectors create a vector field which we define as the spatial velocity.
Let’s continue with an example.
2.1.1. Spinning Top¶
We will use an example: spinning top on a cart to explain following sections.
Note the vector field will change over time. |
2.1.2. Relationship between conventional velocities¶
Selecting 2 points A and B from the vector field of spinning top. Their velocities are related as following:
2.1.3. Spatial Velocity in Coordinates¶
As shown above, to get velocity of point B we only need . We can define B as any point in the vector space, then compute its velocity. That means is sufficient to uniquely define the vector field.
For rigid body motion assigning a coordinate frame to point A.
Attention
The set of vectors describing rigid body velocities is a 6-dim vector space.
As we write the spatial velocity as a 6-dim vector, we concatenate the linear and angular components. Their order verify from author to author, we use angular components first.
Example 1
The coordinate system such as the one in the above example is used to construct a basis which defines all possible rigid body motion. This basis is called as the Plücker Coordinates. Then using them, we can express the velocity in the example as following:
2.2. Transforming Spatial Velocity¶
Note
Check out Variable-Frame Notation
Consider a moving rigid body; two coordinate frames, A and B can be used to express its velocity. To transform between them:
We obtained which allows a change of basis from Plucker coords with respect to frame A to frame B. Meanwhile we also defined to replace cross-product, for clarity. (Cross product)
2.3. Moving Frames¶
where the first term stands for coordinate axes moving; and the second term for the change in coordinates.
Note
is meaningful without coordinates. We say this operation is coordinate invariant.
Considering the drawing above, we could compute as following:
So, it does not matter much where the computation is performed. It is easy to change/assign a coordinate frame.
2.4. Spatial Acceleration¶
Just like spatial velocity, spatial acceleration is a vector field and it is equal to
Similar to spatial velocity, spatial acceleration is defined by a 6-dim vector space.
Consider Example 1, its spatial acceleration is 0 everywhere. Considering frame O is inertially fixed:
in which
First three components give angular acceleration.
Last three give rate of change in flow of body-fixed particles through {O}.
Example 2
2.5. Spatial Cross Product - Velocity¶
Here we introduced as the spatial cross product.
In frame O:
In frame A:
Attention
As seen in two samples above: spatial cross product is coordinate invariant.
Note
Note the structural similarity with the Moving Frames.
The first term accounts for the moving coordinate; second term for the changing coordinates
Example 3
2.6. Relationship Between Spatial & Conventional Acceleration¶
Todo
Clear it up, find better equations(?)
: time rate of change of velocity of body-fixed particles at point O.
2.7. Spatial Forces¶
It is a 6-dim vector which combines a force through a point and a moment through the same point.
which defines the transform for the spatial forces.
2.8. Spatial Momentum¶
In a similar fashion to other spatial quantities we combine angular and linear momentum to get a 6-dim vector. {c} denotes center of mass (CoM), whereas {A} is the origin of some arbitrary frame.
2.9. Spatial Dynamics¶
We introduced a new spatial cross product above; this one can be used for forces and momenta.
Attention
Resulting equation is valid for any frame: moving, non-center of mass, etc.

Just to make this all abit less confusing for you, here's some background information. At the time of my first and only acid trip, I was six years old and living with three of my grown/teenaged cousins because of issues with my imidiate family. My cousins were deeply involved with the drug culture. They manufactured, sold and binged on numerous types of drugs frequently during my time with them and as far as I know, still do.
Ok, now for the story. We were going on a road trip for a reason I still do not remember and don't actually think I ever knew. We were in the Reno, Nevada area in my eldest cousin's (Will's) old hippie van. Me and Logan (the youngest) were sitting in the back talking and he started tell me about acid. he made it sound like such a magical drug that would make everything better. I told him the I would love to try it sometime. He said he had a hit on him and offered it. I accepted. I popped it and resumed talking with him. I quickly forgot all about it and the effect came as quite a surprise.
After about and hour I started to feel the effects, which started with calidescopic patterns ariving on the inside of my eyelides. For some reason seeing these things made me giggle and everyone started looking at me, and Logan explained how he had given me acid. Will (the oldest) started bitching at him how I was to young to do stuff that hard because I might see something that could traumitize me. As soon as Logan relized that he regretted ever giving it to me.
Soon it was open eye hilucinations and the posters on the roof of the van seem to be coming out at me and coming alive and moving. For example, one of his Marilyn Manson posters (The one where MM looks like he's a female alien) appeared to be walking and waving to me.  Then I started thinking in ways no 6 yr old would ever think, I began relizing how wrong what my cousin's were doing was. And then a police car went by us and I thought it was coming for us and I began crying.
Logan told me to shut up and that it would be over soon. Then I started having flashbacks to the past year, recalling an incident where I was sexually abused by one of my cousins that I had until that point forgotten about. I attacked the one that had done this to me, screaming why and punching him and crying. One of the others managed to pull me off him and kept me pinned to the floor until I calmed down but I was stilled very shaken. Will said that we would arrive soon and that I can't be in this state when we do. So he insisted that we stop at a motel until I come off, by then about 3 hrs had past since I first started feeling the effects.
So we stopped and ate a junk food dinner, and I was told to sleep through the rest, which was difficult and unenjoyable. But I managed to do so and when I woke up I felt fine and we continued the trip drug free. I had no dreams while on acid, at least none that I remember. I had been given whiskey to prevent this and it worked. I do think acid would be a good drug to try under the right circumstances and certainly not at the age I had done it. I would do acid again if given the oppurtunity.

| Attitude and characteristics | Diego loves to see what local artists come up with and is a frequent visitor of art galleries, shows, and exhibits. |
| Personal Challenges | Diego spends a lot of time finding auditions for local acting opportunities, practicing his lines, and waiting around sets so he doesn't have many opportunities to go visit the galleries up in Santa Fe or even dabble in Albuquerque's local art scene. |
| Needs/ Goals | Diego wants to experience the 505's various art flavors without having to cut into his career. |
| Frustrations | Diego hates visiting sites with slow upload speeds or ones that aren't very mobile friendly. |
"My name is Diego Escobar. I love New Mexican art and am always excited to see what local artists have come up with. Unfortunately, I don't have much time to go indulge myself, but my friend told me about the-arts-haus.org and I think I am going to check it out."
| Title: | Diego creates a profile with the-arts-haus.org and browses through some local art pieces. |
|---|---|
| Description | Many local artists have joined the digital revolution and have profiles on the-arts-haus.org, so Diego will have a lot of pictures to feast his eyes on. |
| Name of user & their role | Diego is a browsing user of the-arts-haus.org so he'll create a profile so he can like, favorite and comment on art without actually uploading any of his own work to his profile. |
| Usage preconditions | Diego needs internet access, a computer or phone and he'll need to create an account with the-arts-haus.org so he can like, favorite and comment on what he sees. |
| Usage postconditions | Diego finds a plethora of local art that he likes, favorites several pieces and follows several artist's profiles. |
| Interaction flow |
|---|
| Diego searches for the the-arts-haus.org and the browser loads the site's landing page. |
| Diego clicks on the hamburger button which transforms into a drop down menu. |
| He clicks sign in which takes him to the sign in page. |
| The sign-in page contains a sign-in window along with a button to sign-up. Diego clicks sign-up. |
| The server loads the sign-up page with various fields for Diego to fill out. |
| Diego fills out the fields and submits the information and the server takes him to landing page. |
| On the landing page Diego scrolls through the sites pictures and clicks on one that catches his eye. |
| The server delivers a pop-up of the image which includes info on the artist and an option to applaud. |
| Diego applauds the image multiple times and the server adds his applause to the image pop-up's applaud counter. |
| Diego clicks out of the image and the server returns him back to where he was on the landing page's image scroll section. |

Since Claynce is a clay court tennis management robot that autonomously sweeps/cleans/levels-out clay courts, Claynce would be a perfect asset to tennis clubs worldwide.
As per standard calculations, clay courts take around 8-10 minutes to sweep before, during and after matches. For tennis clubs with various courts and bookings throughout the day, the manpower that goes behind maintenance marks for a big factor in budgeting. With Claynce, however, tennis clubs would be able to invest in our long-term product, and allocate their savings to other areas in their expenditures.Our robot, when given a task, moves around the court in a predefined pattern, sweeping it and evening out the clay surface with a net attached to the back.
Find out more about Claynce features here.
Also, check out our User Guide to get to know how to use Claynce system in detail.
The potential marker is really huge. There are over 9,000 clay courts in the Germany alone, and an even more astounding 32,000 courts in the USA. Furthermore, approximately 95% of tennis courts in central-west Europe are clay courts.
On top of that, Claynce is a versatile robot, that with some further enhancements, could be applicable to other tennis court surfaces. Moreover, thanks to its robust visual localization algorithm,, it could be made to work in different environments, such as squash or vollayball courts making it a truly universal system.

Scenario 2 : Agent on a Computer Configured For Constrained Delegation
If you are able to compromise a computer account that is configured for constrained delegation (instead of a user account) the attack approach is a bit different. As any process running as SYSTEM takes on the privileges of the local machine account, we can skip the Kekeo asktgt.exe step. You can also use an alternative method to execute the S4U2Proxy process, helpfully provided by Microsoft. Lee and I translated the process from C# into PowerShell as follows:
# translated from the C# example at https://msdn.microsoft.com/en-us/library/ff649317.aspx
# load the necessary assembly
$Null = [Reflection.Assembly]::LoadWithPartialName('System.IdentityModel')
# execute S4U2Self w/ WindowsIdentity to request a forwardable TGS for the specified user
$Ident = New-Object System.Security.Principal.WindowsIdentity<EMAIL_ADDRESS># actually impersonate the next context
$Context = $Ident.Impersonate()
# implicitly invoke S4U2Proxy with the specified action
ls \\PRIMARY.TESTLAB.LOCAL\C$
# undo the impersonation context
$Context.Undo()
As detailed by Microsoft, when using WindowsIdentity, an “identify-level” token is returned by default for most situations. This allows you to see what groups are associated with the user token, but doesn’t allow you to reuse the access. In order to use the impersonation context to access additional network resources, an impersonation-level token is needed, which is only returned when the requesting account has the “
Also, due to some of the powershell.exe peculiarities I mentioned a bit ago, if you are using PowerShell Version 2, you need to launch powershell.exe in single-thread apartment mode (with the “-sta” flag) in order for the token impersonation to work properly:


Java Tutorial
- Java is a high level, modern programming language designed in the early 1990s by sun Microsystems, and currently owned by Oracle.
- Java programs are platform independent which means they can be run on any operating system with any type of processor as long as the Java interpreter is available on that system.
- Java code that runs on one platform does not need to be recompiled to run on another platform, it’s called “write once, run anywhere” (WORA).
A Hello World Program:
class MyClass{
public static void main(String [ ] args){
System.out.println(“Hello World”);
}
- Every line of code in Java that can run should be inside a class.
- All class names required to start with a capital letter
- In this example, MyClass is the name of the class already created.
- The word Public means that it is accessible by any other classes.
- The word Static means that it is unique( the method can be run without creating an instance of the class containing the main method)
- The word Void means this main method has no return value.
- Main is a method where the program starts.
- You will notice that the main method code has been moved to some spaces left. This is called indentation which used to make a program easier to read and understand.
Example:
void test();
- This code declares a method called test, which does not return anything and has no parameters.
-
The method’s parameters are declared inside the parentheses that follow the name of the method.
- The body of the main method, enclosed in curly braces:
{
System.out.println(“Hello World”);
}
- The println method prints a line of text to the screen.
- The System class and its out stream are used to access the println method.
Note: In java every code statement must end with a semicolon.
Java Comments:
The purpose of including comments in a code is to explain what the code is doing.
Java supports both single and multi-line comments. All characters that appear within a comment are ignored by the Java compiler. * A single-line comment starts with two forward slashes and continues until it reaches the end of the line. * Java also supports comments that span multiple lines. This type of comment starts with a forward slash followed by an asterisk, and ends with an asterisk followed by a forward slash.
For example:
/* This is also a comment spanning multiple lines */
Note: Java does not support nested multi-line comments. However, you can nest single-line comments within multi-line comments.
For example:
/* This is a single-line comment:
// A single-line comment
*/
Documentation comments :
Documentation comments are special comments that have the appearance of multi-line comments, with the difference being that they generate external documentation of your source code.
These begin with a forward slash followed by two asterisks, and end with an asterisk followed by a forward slash.
Javadoc is a tool which comes with JDK and it is used for generating Java code documentation in HTML format from Java source code which has required documentation in a predefined format.
When a documentation comment begins with more than two asterisks, Javadoc assumes that you want to create a “box” around the comment in the source code. It simply ignores the extra asterisks.
For example:
/*************
This is the start of a method

( This will retain just the text “this is the start of a method” for the documentation).
Variables:
Variables store data for processing. A variable is given a name (or identifier), such as area, age, and height. The name uniquely identifies each variable, assigning a value to the variable and retrieving the value stored. Variable has types. Some examples:
- int : for integer (whole numbers) such as 123 and - 406.
- double : for floating-point or real numbers with optional decimal points and fractional parts in fixed or scientific notations, such as 3.1416, -80.44.
- String : for texts such as “Hello” or “Good morning”. Text strings are enclosed within double quotes.
- Char : stands for character and holds a single character such as ‘Z’.
You can declare a variable of a type and assign it a value.
For example: string name = “David”;
This creates a variable called name of type String, and assigns it the value “David”.
Note: It is important to note that a variable is associated with a type, and is only capable to storing values of that particular type. For example, an int variable can store integer values, such as 123; but it cannot store real numbers such as 13.1416, or texts, such as “Hello”.

You may lock the container (avoid any further events inside it) by using dropOptions.canEnter handler. In this example first bin handle events for oranges only, and second bin — for plums.
Please note green-colored response from accepting container: it's one example of drag-drop classes dynamically applied to elements (in this case .drop-target-over-valid) and we use it to decorate accepting container.

Note
This memo documents a part of TinyOS for the TinyOS Community, and requests discussion and suggestions for improvements. Distribution of this memo is unlimited. This memo is in full compliance with TEP 1.
This memo documents a set of hardware-independent interfaces to non-volatile storage for TinyOS 2.x. It describes some design principles for the HPL and HAL layers of various flash chips.
Flash chips are a form of EEPROM (electrically-erasable, programmable read-only memory), distinguished by a fast erase capability. However, erases can only be done in large units (from 256B to 128kB depending on the flash chip). Erases are the only way to switch bits from 0 to 1, and programming operations can only switch 1's to 0's. Additionally, some chips require that programming only happen once between each erase, or that it be in relatively large units (e.g., 256B).
In the table below, we summarise these differences by categorising flash chips by their underlying technology (NOR vs NAND). We also include a column for Atmel's AT45DB flash chip family, as it has significantly different tradeoffs than other flash chips:
X NOR (ex: ST M25P40, Intel PXA27x) AT45DB NAND (ex: Samsung K9K1G08R0B) Erase Slow (seconds) Fast (ms) Fast (ms) Erase unit Large (64KB-128KB) Small (256B) Medium (8KB-32KB) Writes Slow (100s kB/s) Slow (60kB/s) Fast (MBs/s) Write unit 1 bit 256B 100's of bytes Bit-errors Low Low High (requires ECC, bad-block mapping) Read Bus limited [*] Slow+Bus limited Bus limited Erase cycles 10^4 - 10^5 10^4 [†] 10^5 - 10^7 Intended use Code storage Data storage Data storage Energy/byte 1uJ 1uJ .01uJ
| [*] | M25P40 reads are limited by the use of a 25MHz SPI bus. The PXA27x flash is memory mapped (reads are very fast and can directly execute code). |
| [†] | Or infinite? Data sheet just says that every page within a sector must be written every 10^4 writes within that sector |
The energy/byte is the per-byte cost of erasing plus programming. It is derived from the timing and power consumption of erase and write operations (for NOR flash, values are for the STMicroelectronics M25P family, for NAND flash, values are from the Samsung datasheet). Energy/byte for reads appears to depend mostly on how long the read takes (the power consumptions are comparable), i.e., on the efficiency of the bus + processor.
Early TinyOS platforms all used a flash chip from the AT45DB family. In TinyOS 1.x, this chip could be accessed through three different components:
Some more recent platforms use different flash chips: the ST M25P family (Telos rev. B, eyes) and the Intel Strataflash (Intel Mote2). None of the three components listed above are supported on these chips:
One approach to hiding the differences between different flash chips is to provide a disk-like, block interface (with, e.g., 512B blocks). This is the approach taken by compact flash cards. However, in the context of TinyOS, this approach has several drawbacks:
A second approach is to provide a generic low-level interface providing operations (read, write, erase) corresponding to the basic flash operations, along with information describing the flash chip's layout (minimum write and erase unit, timing information, etc). However, we believe that the large differences between NAND and NOR flash (see the table above), in particular the differences in reliability, write and erase units, make the design of a useful generic low-level interface tricky at best.
We thus believe it is best, for now at least, to define high-level storage abstractions that are useful for sensor network applications, and leave their implementation up to each flash chip - such abstractions will be necessary anyway. We leave open the possibility that a future TEP may define portable lower-level flash interfaces (either for all flash chips, or, e.g., for NOR-family flashes). Such low-level interfaces would allow implementations of the storage abstractions defined in this TEP to be used for multiple flash chips.
This TEP describes three high-level storage abstractions: large objects written in a single session, small objects with arbitrary reads and writes, and logs. TinyOS 2.x, divides flash chips into separate volumes (with sizes fixed at compile-time). Each volume provides a single storage abstraction (the abstraction defines the format).
We prefer the use of single abstractions over fixed-size volumes over the use of a more general filing system (like Matchbox) for several reasons:
New abstractions (including a filing system) can easily be added to this framework.
The rest of this TEP covers some principles for the organisation of flash chips (Section 3), then describes the flash volumes and storage abstractions in detail (Section 4).
The flash chip architecture follows the three-layer Hardware Abstraction Architecture (HAA), with each chip providing a presentation layer (HPL, Section 3.1), adaptation layer (HAL, Section 3.2) and platform-independent interface layer (HIL, Section 3.3) [2]. The implementation of these layers SHOULD be found in the tos/chips/CHIPNAME directory. If a flash chip is part of a larger family with a similar interface, the HAA SHOULD support all family members by relying, e.g., on platform-provided configuration information.
Appendix A shows example HPL and HAL specifications for the AT45DB and ST M25P chip families.
The flash HPL has a chip-dependent, platform-independent interface. The implementation of this HPL is platform-dependent. The flash HPL SHOULD be stateless.
To remain platform independent, a flash chip's HPL SHOULD connect to platform-specific components providing access to the flash chip; these components SHOULD be placed in the tos/platforms/PLATFORM/chips/CHIPNAME directory. If the flash chip implementation supports a family of flash chips, this directory MAY also contain a file describing the particular flash chip found on the platform.
The flash HAL has a chip-dependent, platform-independent interface and implementation. Flash families with a common HPL SHOULD have a common HAL. Flash HAL's SHOULD expose a Resource interface and automatically power-manage the underlying flash chip. Finally, the flash HAL MUST provide a way to access the volume information specified by the programmer (see Section 3). This allows users to build new flash abstractions that interact cleanly with the rest of the flash system.
Each flash chip MUST support at least one of the storage abstractions described in Section 4. These abstractions SHOULD be presented in components named ChipAbstractionC, e.g., At45dbLogStorageC. Additionally, a flash chip implementation MAY support platforms with multiple instances of the same storage chip. The way in which this is achieved is not specified further in this TEP.
Each platform MUST have AbstractionC components (e.g., LogStorageC) implementing the storage abstractions of Section 4 supported by its flash chip(s). On platforms with multiple storage chips SHOULD redirect uses of AbstractionC to the appropriate storage chip, based on the requested volume.
The HIL implementations are platform-independent, but chip (family) dependent. They implement the three storage abstractions and volume structure discussed in the introduction.
The division of the flash chip into fixed-size volumes is specified by an XML file that is placed in the application's directory (where one types 'make'). The XML file specifies the allocation as follows:
<volume_table> <volume name="DELUGE0" size="65536" /> <volume name="CONFIGLOG" size="65536" /> <volume name="DATALOG" size="131072" /> <volume name="GOLDENIMAGE" size="65536" base="983040" /> </volume_table>
The name and size parameters are required, while base is optional. The name is a string containing one or more characters in [a-zA-Z0-9_], while size and base are in bytes. Each storage chip MUST provide a compile-time tool that translates the allocation specification to chip-specific nesC code. There is no constraint on how this is done or what code is produced, except that the specification to physical allocation MUST be one-to-one (i.e. a given specification should always have the same resulting physical allocation on a given chip) and the result MUST be placed in the build directory. When not specified, the tool picks a suitable physical location for a volume. If there is any reason that the physical allocation cannot be satisfied, an error should be given at compile time. The tool SHOULD be named tos-storage-CHIPNAME and be distributed with the other tools supporting a platform. The XML file SHOULD be named volumes-CHIPNAME.xml.
The compile-time tool MUST prepend 'VOLUME_' to each volume name in the XML file and '#define' each resulting name to map to a unique integer.
The storage abstractions are accessed by instantiating generic components that take the volume macro as argument:
components new BlockStorageC(VOLUME_DELUGE0);
If the named volume is not in the specification, nesC will give a compile-time error since the symbol will be undefined.
A volume MUST NOT be used with more than one storage abstraction instance.
The motivating example for large objects is the transmission or long-term storage of large pieces of data. For instance, programs in a network-reprogramming system, or large data-packets in a reliable data-transmission system. Such objects have an interesting characteristic: each byte in the object is written at most once.
This leads to the definition of the BlockStorageC abstraction for storing large objects or other "write-once" objects:
Large objects are accessed by instantiating a BlockStorageC component which takes a volume id argument:
generic configuration BlockStorageC(volume_id_t volid) { provides { interface BlockWrite; interface BlockRead; } } ...
The BlockRead and BlockWrite interfaces (briefly presented in Appendix B) contain the following operations (all split-phase, except BlockRead.getSize):
For full details on arguments and other considerations, see the comments in the interface definitions.
Note that these interfaces contain no direct support for verifying the integrity of the BlockStorage data, but such support can easily be built by using the computeCrc command and storing the result in a well-defined location, and checking this CRC when desired.
Event and result logging is a common requirement in sensor networks. Such logging should be reliable (a mote crash should not lose data). It should also be easy to extract data from the log, either partially or fully. Some logs are linear (stop logging when the volume is full), others are circular (the oldest data is overwritten when the volume is full).
The LogStorageC abstraction supports these requirements. The log is record based: each call to LogWrite.append (see below) creates a new record. On failure (crash or reboot), the log MUST only lose whole records from the end of the log. Additionally, once a circular log wraps around, calls to LogWrite.append MUST only lose whole records from the beginning of the log.
Logs are accessed by instantiating a LogStorageC component which takes a volume id and a boolean argument:
generic configuration LogStorageC(volume_id_t volid, bool circular) { provides { interface LogWrite; interface LogRead; } } ...
If the circular argument is TRUE, the log is circular; otherwise it is linear.
The LogRead and LogWrite interfaces (briefly presented in Appendix B) contain the following operations (all split-phase except LogWrite.currentOffset, LogRead.currentOffset and LogRead.getSize):
LogWrite.erase: erase the log. A log MUST be erased (possibly in some previous session) before any other operation can be used.
LogWrite.append: append some bytes to the log. In a circular log, this may overwrite the current read position. In this case, the read position MUST be advanced to the log's current beginning (i.e., as if LogRead.seek had been called with SEEK_BEGINNING). Additionally, the LogWrite.appendDone event reports whenever, in a circular log, an append MAY have erased old records.
Each append creates a separate record. Log implementations may have a maximum record size; all implementations MUST support records of up to 255 bytes.
LogWrite.sync: guarantee that data written so far will not be lost to a crash or reboot (it can still be overwritten when a circular log wraps around). Using sync MAY waste some space in the log.
LogWrite.currentOffset: return cookie representing current append position (for use with LogRead.seek).
LogRead.read: read some bytes from the current read position in the log and advance the read position.
LogStorageC implementations MUST include error detection codes to increase the likelihood of detection of corrupted or invalid log data. Data returned by a successful read MUST have passed this error detection check. The behaviour on failure of this check is unspecified (e.g., the at45db believes as if the end of the log has been reached; other implementations may behave differently).
LogRead.currentOffset: return cookie representing current read position (for use with LogRead.seek).
LogRead.seek: set the read position to a value returned by a prior call to LogWrite.currentOffset or LogRead.currentOffset, or to the special SEEK_BEGINNING value. In a circular log, if the specified position has been overwritten, behave as if SEEK_BEGINNING was requested.
SEEK_BEGINNING positions the read position at the beginning of the oldest record still present in the log.
After reboot, the current read position is SEEK_BEGINNING.
LogRead.getSize: return an approximation of the log's capacity in bytes. Uses of sync and other overhead may reduce this number.
For full details on arguments, etc, see the comments in the interface definitions.
Note that while each call to append logically creates a separate record, the LogStorageC API does not report record boundaries. Additionally, crashes, reboots, and appends after wrap-around in a circular log can cause the loss of multiple consecutive records. Taken together, these restrictions mean that a LogStorageC implementation MAY internally aggregate several consecutive appends into a single record. However, the guarantee that only whole records are lost is sufficient to ensure that applications do not to have worry about incomplete or inconsistent log entries.
Sensor network applications need to store configuration data, e.g., mote identity, radio frequency, sample rates, etc. Such data is not large, but losing it may lead to a mote misbehaving or losing contact with the network.
The ConfigStorageC abstraction stores a single small object in a volume. It:
Small objects are accessed by instantiating a ConfigStorageC component which takes a volume id argument:
generic configuration ConfigStorageC(volume_id_t volid) { provides { interface Mount; interface ConfigStorage; } } ...
A small object MUST be mounted (via the Mount interface) before the first use.
The Mount and ConfigStorage interfaces (briefly presented in Appendix B) contain the following operations (all split-phase except ConfigStorage.getSize and ConfigStorage.valid):
For full details on arguments, etc, see the comments in the interface definitions.
An AT45DB implementation can be found in tinyos-2.x/tos/chips/at45db.
An ST M25P implementation can be found in tinyos-2.x/tos/chips/stm25p.

The Atmel AT45DB family HPL is:
configuration HplAt45dbC { provides interface HplAt45db; } ...
The HplAt45db interface has flash->buffer, buffer->flash, compare buffer to flash, erase page, read, compute CRC, and write operations. Most of these operations are asynchronous, i.e., their completion is signaled before the flash chip has completed the operation. The HPL also includes operations to wait for asynchronous operations to complete.
A generic, system-independent implementation of the HPL (HplAt45dbByteC) is included allowing platforms to just provide SPI and chip selection interfaces.
Different members of the AT45DB family are supported by specifying a few constants (number of pages, page size).
The AT45DB HAL has two components, one for chip access and the other providing volume information:
component At45dbC { provides { interface At45db; interface Resource[uint8_t client]; interface ResourceController; interface ArbiterInfo; } } ... configuration At45dbStorageManagerC { provides interface At45dbVolume[volume_id_t volid]; } ...
Note that the AT45DB HAL resource management is independent of the underlying HPL's power management. The motivation for this is that individual flash operations may take a long time, so it may be desirable to release the flash's bus during long-running operations.
The At45db interface abstracts from the low-level HPL operations by:
It provides cached read, write and CRC computation, and page erase and copy. It also includes flush and sync operations to manage the cache.
The At45dbVolume interface has operations to report volume size and map volume-relative pages to absolute pages.
The ST M25P family HPL is:
configuration Stm25pSpiC { provides interface Init; provides interface Resource; provides interface Stm25pSpi; }
The Stm25pSpi interface has read, write, compute CRC, sector erase and block erase operations. The implementation of this HPL is system-independent, built over a few system-dependent components providing SPI and chip selection interfaces.
Note that these two examples have different resource management policies: the AT45DB encapsulates resource acquisition and release within each operation, while the M25P family requires that HPL users acquire and release the resource itself.
The ST M25P HAL is:
configuration Stm25pSectorC { provides interface Resource as ClientResource[storage_volume_t volume]; provides interface Stm25pSector as Sector[storage_volume_t volume]; provides interface Stm25pVolume as Volume[storage_volume_t volume]; }
The Stm25pSector interface provides volume-relative operations similar to those from the HPL interface: read, write, compute CRC and erase. Additionally, it has operations to report volume size and remap volume-relative addresses. Clients of the ST M25P HAL must implement the getVolumeId event of the Stm25pVolume interface so that the HAL can obtain the volume id of each of its clients.
These interfaces are presented briefly here for reference; please refer to the TinyOS documentation for a full description of the commands, events and their parameters.

Immediately after I took the first pill I was nauseated, it didn't matter if it was taken with food at all. I was feeling faint & dizzy and definitely not in the mood for anything. I tortured my body for 6 days and I couldn't bring myself to swallow another pill on day 7.
I was constantly feeling crappy and a few times I did throw up...I've been off bc for over 15 years
SENT4
and I just continue to use condoms! Ps I only started it to regulate my period and I had just finished my period and started that Sunday, I've been off the pill for 3 days after only taking it for 6 days and I'm bleeding again ! So I had a period on august 30th and I'm now on my period again and it's September 12th ! 13 days apart !!! NEVER AGAIN

Cranky Critic® Reviews: Stigmata Starring Patricia Arquette, Gabriel Byrne, Jonathan Pryce Screenplay by Tom Lazarus and Rick Ramage Directed by Rupert Wainwright website: www.mgm.com/stigmata
IN SHORT: A great commercial for a non-scary flick.
If you were fascinated by the Stigmata television commercial, try to imagine watching 60 straight minutes of it. That editing overkill is what stops Stigmata dead in its tracks as a movie. If it were a mathematical formula, Stigmata would = (Blade - vampires) + (The Exorcist - pea soup and obscenity) / story. Drawing heavily from Christian mysticism and attacking the inner political construction of the Roman Catholic church, Stigmata spends more time allowing director Rupert Wainwright to show off his photographic knowledge and editing chops than it does on the story. Cranky was ready to yell at the screen "Hey! It's story time already" when just enough intrigue dribbled out to keep his attention focussed for a few more minutes. Unfortunately it was way too little, far too late.
Stigmata features a lot of effects -- levitation, blood, fire -- and one, true mystery: how is it that the wounds of Christ manifest themselves on the body of a cute blonde resident of Pittsburgh, PA? The Vatican has a special section, the Special Congregation for the Causes of Saints -- whose job it is to investigate religious mysteries and its Cardinal Houseman (Jonathan Pryce) dispatches Father Andrew Kiernan (Gabriel Byrne) to investigate. This is the second investigation Kiernan does in this movie, the first involving a South American statue of the Virgin Mary that weeps tears of human blood. There's a tenuous link between the two, but I'll leave that for you to discover.
When Kiernan finds the lovely Frankie Paige (Patricia Arquette), his investigation ends almost as quickly as it begin, for Frankie is not a member of the True Church. That means she, and her wounds, is of no interest to his section. But Frankie speaks in tongues -- turns out to be the kind of Aramaic spoken 2000 years ago in Galilee -- and has scribbled strange characters on the walls of her loft. They, too, are Aramaic, and the words therein are part of a hidden document that could shake the theosophical nature of the Vatican to its core.
Stigmata features a gorgeous first hour of photographic effects and heavy duty editing over a soundtrack of techno-heavy metal music. for purposes of this film, it is constantly raining in Pittsburgh, which means lots of slow motion shots of water dripping and plopping. The Catholic Church being loaded with symbols and icons, this film also goes heavy on symbolic things whose meaning is quite beyond the knowledge of this Member of the Tribe. What I do know is that Stigmata is based on two fragments (part of phrase 3 and the latter half of phrase 77) of the Dead Sea Scroll called The Gospel of Thomas, which this film has used to create a "new" text that is even more heretical than the "Thomas". Anyone that has studied the Dead Sea Scrolls (Cranky pleads guilty) can tell you that there are lots of tempting heretical bits and pieces that would fascinate anyone that has even a mild knowledge of Christianity. Stigmata drowns any interesting mystery in so much visual nonsense that it defeats the purpose of any movie, to tell a good and interesting story. There is a story here, but it's buried way too deep. And, of course, time is wasted while the priest is tempted by the blonde . Been there, done that.
On average, a first run movie ticket will run you Eight Bucks. Were Cranky able to set his own price to Stigmata, he would have paid...
$3.00
Rental level. Oh, yeah. The Gospel of Thomas is attributed to Didymos Judas Thomas, founder of the Eastern Church and Twin Brother of Jesus. Told ya it was a good bit of heretical bit info. Theoretically, the Gospel of Mary is even worse, 'cuz it strips the Vatican of any authority as guardian and sole arbiter of the Word. But that's a story for a different movie.

Wendy Williams Slams Taylor Swift’s Artist Of The Decade Title At The AMAs
by Corey AtadTaylor Swift had a huge night at the 2019 AMAs on Sunday, but not everyone was here for it.
On Monday, Wendy Williams took some time on her show to called out the singer for winning Artist of the Decade and breaking the record for most AMA wins.
“Taylor Swift made history, which is, like, unbelievable to me,” Williams said, according to toofab.
“And so, good for her. She won six awards, now she has a total of 29 awards,” she continued. “That sounds unbelievable, but what sounds unforgivable, she’s got more awards than Michael Jackson!”
Williams added, “And Artist of the Decade?! Is she who’s been firing you up for the last 10 years?!”
The TV host then lamented the general state of public taste.
“But you know what? I think that taste has cheapened through the years in a lot of things,” she said. “The quality of clothes we buy, they get tattered and torn real quick. The quality of food we buy, we’re being poisoned by a lot of crap. Just life in general I think has cheapened and I don’t mean this in a bad way to Taylor, but it’s unbelievable … I appreciate her, but Artist of the Decade?”


This module wraps the ShareKit 2.0 framework for iOS devices (both iPhone and iPad).
For more information about ShareKit 2.0 visit the source repository at https://github.com/ShareKit/ShareKit
http://wiki.appcelerator.org/display/tis/Using+Titanium+Modules
See here
Lots of things changed. Please read the changelog and re-read the configuration section to see what changed and what you need to adapt on your application.
To access this module from JavaScript, you would do the following:
var sharekit = require("com.0x82.sharekit");
The sharekit variable is a reference to the Module object.
This modules exposes three simple methods.
This is required and should be the first thing you call on the module. All the configuration parameters can be found on the configuration page.

VNC is a well-known tool for remote desktop view and control. The two computers establish a TCP connection so that one of them can access the display of the other. However, almost always these two computers are behind a firewall/router and do not have a real IP to be accessed from the Internet. In such a case one of them can do port forwarding on the router/firewall and this would allow the connection to be established. The problem is that more often than not, none of the parts that want to establish such a remote connection have access to the firewall that separates/protects it from the real internet. Sometimes it can even be several levels deep behind the firewall (several layers of firewalls). However, if you have access to an external server (for example a server in the cloud) there is still a workaround and things can be fixed to work. Here I will explain the tricks and hacks that can be used in such a case in order to establish a secure connection to a remote desktop.
Let's say that we have a computer A that wants to connect to the desktop of a computer B. Both of them are behind a NAT router/firewall and cannot modify its settings. However both of them can access a third computer C that is somewhere on the cloud and has a real IP.
It is possible to use C as a redirecter of the traffic, so that both computers A and B can establish a direct (peer-to-peer) connection between them. This is done using the wonderful features for tunneling and port-forwarding of the SSH protocol. What is more, this connection will be encrypted and secure, which is the main feature of the SSH protocol.
I will describe in the other sections what should be done in each of the computers in order to setup such a connection.
On A we need to have a VNC client. Let's install vncviewer:
sudo apt-get install vncviewer
On B we need to have a VNC server. Let's install x11vnc:
sudo apt-get install x11vnc
To connect from A to C and from B to C we can use any existing account on C. However it is better to create a new one. Let's call it vnc:
sudo adduser vnc
Let's assume that there is a sshd server running on C (otherwise there is no way to access it), and let's say that it is running on the port 2201. We will refer to it as middle-server (which can be an IP or a domain name).
To access the desktop of B from A, we first start the VNC server on B:
ssh -p 2201 -t -R 5933:localhost:5900 vnc@middle-server x11vnc -rfbport 5900 -localhost -display :0
Then we start the VNC viewer on A:
ssh -p 2201 -t -L 5900:localhost:5933 vnc@middle-server vncviewer -encodings "copyrect tight zrle hextile" localhost:0
Note: In both cases above, the ssh command and the other command are given on separate terminal tabs. The ssh command creates a ssh tunnel to C for the VNC port 5900, which is mapped to the port 5933 on C.
Now we can enjoy the access to the remote desktop.
The SSH protocol allows authentication by a private-publik key pair. This would be more convenient because this way we don't have to remember the passsword. Also we can restrict the ssh access only for what we need it: tunneling and port-forwarding, and prohibit login etc.
Let's create a private-public key pair for user vnc
on C:
su - vnc mkdir ~/.ssh chmod 700 ~/.ssh ssh-keygen -t rsa ls -al .ssh total 16 drwx------ 2 vnc vnc 4096 Jan 22 09:31 . drwxr-xr-x 3 vnc vnc 4096 Jan 22 09:31 .. -rw------- 1 vnc vnc 1675 Jan 22 09:31 id_rsa -rw-r--r-- 1 vnc vnc 394 Jan 22 09:31 id_rsa.pub
The public key id_rsa.pub
should go to the file authorized_keys
,
and the private key id_rsa
will be used by A and B to login:
cd ~/.ssh/ cp id_rsa.pub authorized_keys cp id_rsa vnc.key
Now we can copy vnc.key
to A and B and then run the commands
like this:
On B: ssh -p 2201 -t -R 5933:localhost:5900 -i vnc.key vnc@middle-server x11vnc -rfbport 5900 -localhost -display :0 On A: ssh -p 2201 -t -L 5900:localhost:5933 -i vnc.key vnc@middle-server vncviewer -encodings "copyrect tight zrle hextile" localhost:0
This time no password will be asked for establishing the ssh connection.
When we run the ssh command, by default it opens a shell on C where you can run commands, besides creating a tunnel and doing port-forwarding. Even if the vnc account that we use for this purpose may have limited access rights on C, this still is a potential threat (security problem), especially if we don't know or cannot trust the person that is sharing the desktop.
Fortunately, it is possible to limit the SSH features that each key
can use. We do this by modifying the file authorized_keys
to look
like this:
command="/bin/sleep<PHONE_NUMBER>",no-agent-forwarding,no-user-rc, no-X11-forwarding,permitopen="localhost:5933" ssh-rsa B3NzaC1...
The long list of no-xyz statements disallow it from doing just about anything except connect to a VNC server.


simple_usertype<T>¶
structures and classes from C++ made available to Lua code (simpler)
This usertype is no difference from regular usertype, but allows much of its work to be done at runtime instead of compile-time. You can reduce compilation times from a plain usertype
when you have an exceedingly bulky registration listing.
You can set functions incrementally to reduce compile-time burden with simple_usertype
as well, as shown in this example. This means both adding incrementally during registration and even adding at runt=time.
You can add functions to both regular and simple usertypes afterwards by adding items to the metatable directly at runtime (e.g., by accessing the named metatable yourself and setting functions on it).
Note
You cannot add functions to an individual object. You can only add functions to the whole class / usertype.
Some developers used simple_usertype
in older versions to have variables automatically be functions. To achieve this behavior, wrap the desired variable into sol::as_function.
The performance seems to be good enough (see below graphs as well) to not warn about any implications of having to serialize things at runtime. You do run the risk of using (slightly?) more memory, since variables and functions need to be stored differently and separately from the metatable data itself like with a regular usertype
. The goal here was to avoid compiler complaints about too-large usertypes (some individuals needed to register 190+ functions, and the compiler choked from the templated implementation of usertype
). As of Sol 2.14, this implementation has been heavily refactored to allow for all the same syntax and uses of usertype to apply here, with no caveats/exceptions.

| faq-error-scalar-type {vctrs} | R Documentation |
This error occurs when a function expects a vector and gets a scalar object instead. This commonly happens when some code attempts to assign a scalar object as column in a data frame:
fn <- function() NULL tibble::tibble(x = fn) #> Error: All columns in a tibble must be vectors. #> x Column `x` is a function. fit <- lm(1:3 ~ 1) tibble::tibble(x = fit) #> Error: All columns in a tibble must be vectors. #> x Column `x` is a `lm` object.
In base R, almost everything is a vector or behaves like a vector. In the tidyverse we have chosen to be a bit stricter about what is considered a vector. The main question we ask ourselves to decide on the vectorness of a type is whether it makes sense to include that object as a column in a data frame.
The main difference is that S3 lists are considered vectors by base R but in the tidyverse that’s not the case by default:
fit <- lm(1:3 ~ 1) typeof(fit) #> [1] "list" class(fit) #> [1] "lm" # S3 lists can be subset like a vector using base R: fit[1:3] #> $coefficients #> (Intercept) #> 2 #> #> $residuals #> 1 2 3 #> -1.000000e+00 -3.885781e-16 1.000000e+00 #> #> $effects #> (Intercept) #> -3.4641016 0.3660254 1.3660254 # But not in vctrs vctrs::vec_slice(fit, 1:3) #> Error: Input must be a vector, not a <lm> object.
Defused function calls are another (more esoteric) example:
call <- quote(foo(bar = TRUE, baz = FALSE)) call #> foo(bar = TRUE, baz = FALSE) # They can be subset like a vector using base R: call[1:2] #> foo(bar = TRUE) lapply(call, function(x) x) #> [[1]] #> foo #> #> $bar #> [1] TRUE #> #> $baz #> [1] FALSE # But not with vctrs: vctrs::vec_slice(call, 1:2) #> Error: Input must be a vector, not a call.
It’s possible the author of the class needs to do some work to declare their class a vector. Consider reaching out to the author. We have written a developer FAQ page to help them fix the issue.

HTML form elements work a little bit differently from other DOM elements in React, because form elements naturally keep some internal state. For example, this form in plain HTML accepts a single name:
<form>
<label>
Name:
<input type="text" name="name" />
</label>
<input type="submit" value="Submit" />
</form>
This form has the default HTML form behavior of browsing to a new page when the user submits the form. If you want this behavior in React, it just works. But in most cases, it's convenient to have a JavaScript function that handles the submission of the form and has access to the data that the user entered into the form. The standard way to achieve this is with a technique called "controlled components".
In HTML, form elements such as <input>
, <textarea>
, and <select>
typically maintain their own state and update it based on user input. In React, mutable state is typically kept in the state property of components, and only updated with setState()
.
We can combine the two by making the React state be the "single source of truth". Then the React component that renders a form also controls what happens in that form on subsequent user input. An input form element whose value is controlled by React in this way is called a "controlled component".
For example, if we want to make the previous example log the name when it is submitted, we can write the form as a controlled component:
class NameForm extends React.Component {
constructor(props) {
super(props);
this.state = {value: ''};
this.handleChange = this.handleChange.bind(this);
this.handleSubmit = this.handleSubmit.bind(this);
}
handleChange(event) {
this.setState({value: event.target.value});
}
handleSubmit(event) {
alert('A name was submitted: ' + this.state.value);
event.preventDefault();
}
render() {
return (
<form onSubmit={this.handleSubmit}>
<label>
Name:
<input type="text" value={this.state.value} onChange={this.handleChange} />
</label>
<input type="submit" value="Submit" />
</form>
);
}
}
Since the value
attribute is set on our form element, the displayed value will always be this.state.value
, making the React state the source of truth. Since handleChange
runs on every keystroke to update the React state, the displayed value will update as the user types.
With a controlled component, the input's value is always driven by the React state. While this means you have to type a bit more code, you can now pass the value to other UI elements too, or reset it from other event handlers.
In HTML, a <textarea>
element defines its text by its children:
In React, a <textarea>
uses a value
attribute instead. This way, a form using a <textarea>
can be written very similarly to a form that uses a single-line input:
class EssayForm extends React.Component {
constructor(props) {
super(props);
this.state = {
value: 'Please write an essay about your favorite DOM element.'
};
this.handleChange = this.handleChange.bind(this);
this.handleSubmit = this.handleSubmit.bind(this);
}
handleChange(event) {
this.setState({value: event.target.value});
}
handleSubmit(event) {
alert('An essay was submitted: ' + this.state.value);
event.preventDefault();
}
render() {
return (
<form onSubmit={this.handleSubmit}>
<label>
Essay:
<textarea value={this.state.value} onChange={this.handleChange} />
</label>
<input type="submit" value="Submit" />
</form>
);
}
}
Notice that this.state.value
is initialized in the constructor, so that the text area starts off with some text in it.
In HTML, <select>
creates a drop-down list. For example, this HTML creates a drop-down list of flavors:
<select>
<option value="grapefruit">Grapefruit</option>
<option value="lime">Lime</option>
<option selected value="coconut">Coconut</option>
<option value="mango">Mango</option>
</select>
Note that the Coconut option is initially selected, because of the selected
attribute. React, instead of using this selected
attribute, uses a value
attribute on the root select
tag. This is more convenient in a controlled component because you only need to update it in one place. For example:
class FlavorForm extends React.Component {
constructor(props) {
super(props);
this.state = {value: 'coconut'};
this.handleChange = this.handleChange.bind(this);
this.handleSubmit = this.handleSubmit.bind(this);
}
handleChange(event) {
this.setState({value: event.target.value});
}
handleSubmit(event) {
alert('Your favorite flavor is: ' + this.state.value);
event.preventDefault();
}
render() {
return (
<form onSubmit={this.handleSubmit}>
<label>
Pick your favorite flavor:
<select value={this.state.value} onChange={this.handleChange}>
<option value="grapefruit">Grapefruit</option>
<option value="lime">Lime</option>
<option value="coconut">Coconut</option>
<option value="mango">Mango</option>
</select>
</label>
<input type="submit" value="Submit" />
</form>
);
}
}
Overall, this makes it so that <input type="text">
, <textarea>
, and <select>
all work very similarly - they all accept a value
attribute that you can use to implement a controlled component.
Note
You can pass an array into the
value
attribute, allowing you to select multiple options in aselect
tag:
In HTML, an <input type="file">
lets the user choose one or more files from their device storage to be uploaded to a server or manipulated by JavaScript via the File API.
Because its value is read-only, it is an uncontrolled component in React. It is discussed together with other uncontrolled components later in the documentation.
When you need to handle multiple controlled input
elements, you can add a name
attribute to each element and let the handler function choose what to do based on the value of event.target.name
.
For example:
class Reservation extends React.Component {
constructor(props) {
super(props);
this.state = {
isGoing: true,
numberOfGuests: 2
};
this.handleInputChange = this.handleInputChange.bind(this);
}
handleInputChange(event) {
const target = event.target;
const value = target.type === 'checkbox' ? target.checked : target.value;
const name = target.name;
this.setState({
[name]: value
});
}
render() {
return (
<form>
<label>
Is going:
<input
name="isGoing"
type="checkbox"
checked={this.state.isGoing}
onChange={this.handleInputChange} />
</label>
<br />
<label>
Number of guests:
<input
name="numberOfGuests"
type="number"
value={this.state.numberOfGuests}
onChange={this.handleInputChange} />
</label>
</form>
);
}
}
Note how we used the ES6 computed property name syntax to update the state key corresponding to the given input name:
this.setState({
[name]: value
});
It is equivalent to this ES5 code:
var partialState = {};
partialState[name] = value;
this.setState(partialState);
Also, since setState()
automatically merges a partial state into the current state, we only needed to call it with the changed parts.
Specifying the value prop on a controlled component prevents the
user from changing the input unless you desire so. If you've specified a value
but the input is still
editable, you may have accidentally set value
to undefined
or null
.
The following code demonstrates this. (The input is locked at first but becomes editable after a short delay.)
ReactDOM.render(<input value="hi" />, mountNode);
setTimeout(function() {
ReactDOM.render(<input value={null} />, mountNode);

It can sometimes be tedious to use controlled components, because you need to write an event handler for every way your data can change and pipe all of the input state through a React component. This can become particularly annoying when you are converting a preexisting codebase to React, or integrating a React application with a non-React library. In these situations, you might want to check out uncontrolled components, an alternative technique for implementing input forms.
If you're looking for a complete solution including validation, keeping track of the visited fields, and handling form submission, Formik is one of the popular choices. However, it is built on the same principles of controlled components and managing state — so don't neglect to learn them.


Some tables are created in BaseTen schema to track changes in other relations and storing relationships between tables and views. The association is based on relation names.
While this arrangement allows clients to fault only changed objects, it has some unfortunate side effects:
All this can be done using BaseTen Assistant.
In addition to using BaseTen Assistant, it is possible to enable and disable tables with SQL functions. The functions are baseten.enable (oid) and baseten.disable (oid). The object identifier argument can be looked up from PostgreSQL's system tables, pg_class and pg_namespace.
Views' primary keys are stored in baseten.view_pkey. The table has three columns: nspname, relname and attname, which correspond to the view's schema name, the view's name and each primary key column's name respectively. To enable a view, its primary key needs to be specified first.
Relationships and view hierarchies among other things are stored in automatically-generated tables. These should be refreshed with the SQL function baseten.refresh_caches () after all changes to views, primary keys and foreign keys.


The plugin I talked about in a previous post is now at https://launchpad.net/bzr-removable. Please file bugs.
Thanks to Michael Hudson and Daniel Watkins for submitting patches.
You can get the plugin by typing ‘bzr branch lp:bzr-removable’ on the command line.

I’m sorry that your whole experience of this plugin has been terrible, and I’m glad you’ve gone to the trouble of posting here so that other googlers can find the docs you’ve written.
As this is obviously the first user feedback I’ve received, I would have liked to hear something nice, but perhaps there was nothing nice to say.
Mary says https://bugs.edge.launchpad.net/bzr-removable/+bug/322262
Can you please file bugs on the project on Launchpad?
The full sequence of install steps for this (on UNIX filesystems) is actually:
$ cd [some directory where one normally stores code]
$ bzr branch lp:bzr-removable
$ mkdir -p ~/.bazaar/plugins
$ cd ~/.bazaar/plugins
$ ln -s [some directory]/bzr-removable/removeable
Then “bzr plugins” will verify the install and finally the actual commands one needs are “bzr removable” and “bzr unremovable”
bzr branch lp:bzr-removable ~/code/bzr-removable
ln -s ~/code/bzr-removable/removable ~/.bazaar/plugins/removable


SoundInstance QML Type
Play 3d audio content. More...
| Import Statement: | import QtAudioEngine 1.1 |
| Since: | Qt 5.0 |
| Inherits: |
Properties
- direction : vector3d
- engine : QtAudioEngine::AudioEngine
- gain : vector3d
- pitch : vector3d
- position : vector3d
- sound : string
- state : enumeration
- velocity : vector3d
Signals
- directionChanged()
- gainChanged()
- pitchChanged()
- positionChanged()
- soundChanged()
- stateChanged(state)
- velocityChanged()
Methods
Detailed Description
There are two ways to create SoundInstance objects. You can obtain it by calling newInstance method of a Sound:
Rectangle { id:root color:"white" width: 300 height: 500 AudioEngine { id:audioengine AudioSample { name:"explosion01" source: "explosion-01.wav" } Sound { name:"explosion" PlayVariation { sample:"explosion01" } } } property variant soundEffect: audioengine.sounds["explosion"].newInstance(); MouseArea { anchors.fill: parent onPressed: { root.soundEffect.play(); } } }
Or alternatively, you can explicitly define SoundInstance outside of AudioEngine for easier qml bindings:
Rectangle { id:root color:"white" width: 300 height: 500 AudioEngine { id:audioengine AudioSample { name:"explosion01" source: "explosion-01.wav" } Sound { name:"explosion" PlayVariation { sample:"explosion01" } } } Item { id: animator x: 10 + observer.percent * 100 y: 20 + observer.percent * 80 property real percent: 0 SequentialAnimation on percent { loops: Animation.Infinite running: true NumberAnimation { duration: 8000 from: 0 to: 1 } } } SoundInstance { id:soundEffect engine:audioengine sound:"explosion" position:Qt.vector3d(animator.x, animator.y, 0); } MouseArea { anchors.fill: parent onPressed: { soundEffect.play(); } } }
Property Documentation
direction : vector3d |
This property holds the current 3d direction.
engine : QtAudioEngine::AudioEngine |
This property holds the reference to AudioEngine, must be set only once.
gain : vector3d |
This property holds the gain adjustment which will be used to modulate the audio output level from this SoundInstance.
pitch : vector3d |
This property holds the pitch adjustment which will be used to modulate the audio pitch from this SoundInstance.
position : vector3d |
This property holds the current 3d position.
This property specifies which Sound this SoundInstance will use. Unlike some properties in other types, this property can be changed dynamically.
This property holds the current playback state. It can be one of:
| Value | Description |
|---|---|
| StopppedState | The SoundInstance is not playing, and when playback begins next it will play from position zero. |
| PlayingState | The SoundInstance is playing the media. |
| PausedState | The SoundInstance is not playing, and when playback begins next it will play from the position that it was paused at. |
velocity : vector3d |
This property holds the current 3d velocity.

You said the total number of staff at your workplace was {{ numberOfStaff }}, but
You either need to
It doesn't take long to create a staff record, just add a name or ID number, a main job role and a contract type. You can add extra details when you've got more time.
You still need to add the total number of staff for your workplace.
Both care-providing and none care-providing staff should be included in the total, and you need to add the same number of staff records.
