/* Defining a layer ... */ #include <perliol.h>
The aim of the implementation is to provide the PerlIO API in a flexible and platform neutral manner. It is also a trial of an "Object Oriented C, with vtables" approach which may be applied to Perl 6.
The low levels of the stack work with the low-level operating system calls (file descriptors in C) getting bytes in and out, the higher layers of the stack buffer, filter, and otherwise manipulate the I/O, and return characters (or bytes) to Perl. Terms above and below are used to refer to the relative positioning of the stack layers.
A layer contains a "vtable", the table of I/O operations (at C level a table of function pointers), and status flags. The functions in the vtable implement operations like "open", "read", and "write".
When I/O, for example "read", is requested, the request goes from Perl first down the stack using "read" functions of each layer, then at the bottom the input is requested from the operating system services, then the result is returned up the stack, finally being interpreted as Perl data.
The requests do not necessarily go always all the way down to the operating system: that's where PerlIO buffering comes into play.
When you do an open() and specify extra PerlIO layers to be deployed, the layers you specify are "pushed" on top of the already existing default stack. One way to see it is that "operating system is on the left" and "Perl is on the right".
What exact layers are in this default stack depends on a lot of things: your operating system, Perl version, Perl compile time configuration, and Perl runtime configuration. See PerlIO, "PERLIO" in perlrun, and open for more information.
binmode() operates similarly to open(): by default the specified layers are pushed on top of the existing stack.
However, note that even as the specified layers are "pushed on top" for open() and binmode(), this doesn't mean that the effects are limited to the "top": PerlIO layers can be very 'active' and inspect and affect layers also deeper in the stack. As an example there is a layer called "raw" which repeatedly "pops" layers until it reaches the first layer that has declared itself capable of handling binary data. The "pushed" layers are processed in left-to-right order.
sysopen() operates (unsurprisingly) at a lower level in the stack than open(). For example in Unix or Unix-like systems sysopen() operates directly at the level of file descriptors: in the terms of PerlIO layers, it uses only the "unix" layer, which is a rather thin wrapper on top of the Unix file descriptors.
This is, I hope, a natural term given the implementation, and should avoid connotations that are inherent in earlier uses of "discipline" for things which are rather different.
typedef struct _PerlIO PerlIOl; typedef struct _PerlIO_funcs PerlIO_funcs; typedef PerlIOl *PerlIO; struct _PerlIO { PerlIOl * next; /* Lower layer */ PerlIO_funcs * tab; /* Functions for this layer */ U32 flags; /* Various flags for state */ };
A "PerlIOl *" is a pointer to the struct, and the application level "PerlIO *" is a pointer to a "PerlIOl *" - i.e. a pointer to a pointer to the struct. This allows the application level "PerlIO *" to remain constant while the actual "PerlIOl *" underneath changes. (Compare perl's "SV *" which remains constant while its "sv_any" field changes as the scalar's type changes.) An IO stream is then in general represented as a pointer to this linked-list of "layers".
It should be noted that because of the double indirection in a "PerlIO *", a "&(perlio->next)" "is" a "PerlIO *", and so to some degree at least one layer can use the "standard" API on the next layer down.
A "layer" is composed of two parts:
struct _PerlIO_funcs { Size_t fsize; char * name; Size_t size; IV kind; IV (*Pushed)(pTHX_ PerlIO *f, const char *mode, SV *arg, PerlIO_funcs *tab); IV (*Popped)(pTHX_ PerlIO *f); PerlIO * (*Open)(pTHX_ PerlIO_funcs *tab, PerlIO_list_t *layers, IV n, const char *mode, int fd, int imode, int perm, PerlIO *old, int narg, SV **args); IV (*Binmode)(pTHX_ PerlIO *f); SV * (*Getarg)(pTHX_ PerlIO *f, CLONE_PARAMS *param, int flags) IV (*Fileno)(pTHX_ PerlIO *f); PerlIO * (*Dup)(pTHX_ PerlIO *f, PerlIO *o, CLONE_PARAMS *param, int flags) /* Unix-like functions - cf sfio line disciplines */ SSize_t (*Read)(pTHX_ PerlIO *f, void *vbuf, Size_t count); SSize_t (*Unread)(pTHX_ PerlIO *f, const void *vbuf, Size_t count); SSize_t (*Write)(pTHX_ PerlIO *f, const void *vbuf, Size_t count); IV (*Seek)(pTHX_ PerlIO *f, Off_t offset, int whence); Off_t (*Tell)(pTHX_ PerlIO *f); IV (*Close)(pTHX_ PerlIO *f); /* Stdio-like buffered IO functions */ IV (*Flush)(pTHX_ PerlIO *f); IV (*Fill)(pTHX_ PerlIO *f); IV (*Eof)(pTHX_ PerlIO *f); IV (*Error)(pTHX_ PerlIO *f); void (*Clearerr)(pTHX_ PerlIO *f); void (*Setlinebuf)(pTHX_ PerlIO *f); /* Perl's snooping functions */ STDCHAR * (*Get_base)(pTHX_ PerlIO *f); Size_t (*Get_bufsiz)(pTHX_ PerlIO *f); STDCHAR * (*Get_ptr)(pTHX_ PerlIO *f); SSize_t (*Get_cnt)(pTHX_ PerlIO *f); void (*Set_ptrcnt)(pTHX_ PerlIO *f,STDCHAR *ptr,SSize_t cnt); };
The first few members of the struct give a function table size for compatibility check "name" for the layer, the size to "malloc" for the per-instance data, and some flags which are attributes of the class as whole (such as whether it is a buffering layer), then follow the functions which fall into four basic groups:
A layer does not have to implement all the functions, but the whole table has to be present. Unimplemented slots can be NULL (which will result in an error when called) or can be filled in with stubs to "inherit" behaviour from a "base class". This "inheritance" is fixed for all instances of the layer, but as the layer chooses which stubs to populate the table, limited "multiple inheritance" is possible.
typedef struct { struct _PerlIO base; /* Base "class" info */ STDCHAR * buf; /* Start of buffer */ STDCHAR * end; /* End of valid part of buffer */ STDCHAR * ptr; /* Current position in buffer */ Off_t posn; /* Offset of buf into the file */ Size_t bufsiz; /* Real size of buffer */ IV oneword; /* Emergency buffer */ } PerlIOBuf;
In this way (as for perl's scalars) a pointer to a PerlIOBuf can be treated as a pointer to a PerlIOl.
table perlio unix | | +-----------+ +----------+ +--------+ PerlIO ->| |--->| next |--->| NULL | +-----------+ +----------+ +--------+ | | | buffer | | fd | +-----------+ | | +--------+ | | +----------+
The above attempts to show how the layer scheme works in a simple case. The application's "PerlIO *" points to an entry in the table(s) representing open (allocated) handles. For example the first three slots in the table correspond to "stdin","stdout" and "stderr". The table in turn points to the current "top" layer for the handle - in this case an instance of the generic buffering layer "perlio". That layer in turn points to the next layer down - in this case the low-level "unix" layer.
The above is roughly equivalent to a "stdio" buffered stream, but with much more flexibility:
Size_t fsize;
Size of the function table. This is compared against the value PerlIO code "knows" as a compatibility check. Future versions may be able to tolerate layers compiled against an old version of the headers.
char * name;
The name of the layer whose open() method Perl should invoke on open(). For example if the layer is called APR, you will call:
open $fh, ">:APR", ...
and Perl knows that it has to invoke the PerlIOAPR_open() method implemented by the APR layer.
Size_t size;
The size of the per-instance data structure, e.g.:
sizeof(PerlIOAPR)
If this field is zero then "PerlIO_pushed" does not malloc anything and assumes layer's Pushed function will do any required layer stack manipulation - used to avoid malloc/free overhead for dummy layers. If the field is non-zero it must be at least the size of "PerlIOl", "PerlIO_pushed" will allocate memory for the layer's data structures and link new layer onto the stream's stack. (If the layer's Pushed method returns an error indication the layer is popped again.)
IV kind;
The layer is buffered.
The layer is acceptable to have in a binmode(FH) stack - i.e. it does not (or will configure itself not to) transform bytes passing through it.
Layer can translate between "\n" and CRLF line ends.
Layer allows buffer snooping.
Used when the layer's open() accepts more arguments than usual. The extra arguments should come not before the "MODE" argument. When this flag is used it's up to the layer to validate the args.
IV (*Pushed)(pTHX_ PerlIO *f,const char *mode, SV *arg);
The only absolutely mandatory method. Called when the layer is pushed onto the stack. The "mode" argument may be NULL if this occurs post-open. The "arg" will be non-"NULL" if an argument string was passed. In most cases this should call "PerlIOBase_pushed()" to convert "mode" into the appropriate "PERLIO_F_XXXXX" flags in addition to any actions the layer itself takes. If a layer is not expecting an argument it need neither save the one passed to it, nor provide "Getarg()" (it could perhaps "Perl_warn" that the argument was un-expected).
Returns 0 on success. On failure returns -1 and should set errno.
IV (*Popped)(pTHX_ PerlIO *f);
Called when the layer is popped from the stack. A layer will normally be popped after "Close()" is called. But a layer can be popped without being closed if the program is dynamically managing layers on the stream. In such cases "Popped()" should free any resources (buffers, translation tables, ...) not held directly in the layer's struct. It should also "Unread()" any unconsumed data that has been read and buffered from the layer below back to that layer, so that it can be re-provided to what ever is now above.
Returns 0 on success and failure. If "Popped()" returns true then perlio.c assumes that either the layer has popped itself, or the layer is super special and needs to be retained for other reasons. In most cases it should return false.
PerlIO * (*Open)(...);
The "Open()" method has lots of arguments because it combines the functions of perl's "open", "PerlIO_open", perl's "sysopen", "PerlIO_fdopen" and "PerlIO_reopen". The full prototype is as follows:
PerlIO * (*Open)(pTHX_ PerlIO_funcs *tab, PerlIO_list_t *layers, IV n, const char *mode, int fd, int imode, int perm, PerlIO *old, int narg, SV **args);
Open should (perhaps indirectly) call "PerlIO_allocate()" to allocate a slot in the table and associate it with the layers information for the opened file, by calling "PerlIO_push". The layers is an array of all the layers destined for the "PerlIO *", and any arguments passed to them, n is the index into that array of the layer being called. The macro "PerlIOArg" will return a (possibly "NULL") SV * for the argument passed to the layer.
Where a layer opens or takes ownership of a file descriptor, that layer is responsible for getting the file descriptor's close-on-exec flag into the correct state. The flag should be clear for a file descriptor numbered less than or equal to "PL_maxsysfd", and set for any file descriptor numbered higher. For thread safety, when a layer opens a new file descriptor it should if possible open it with the close-on-exec flag initially set.
The mode string is an ""fopen()"-like" string which would match the regular expression "/^[I#]?[rwa]\+?[bt]?$/".
The 'I' prefix is used during creation of "stdin".."stderr" via special "PerlIO_fdopen" calls; the '#' prefix means that this is "sysopen" and that imode and perm should be passed to "PerlLIO_open3"; 'r' means read, 'w' means write and 'a' means append. The '+' suffix means that both reading and writing/appending are permitted. The 'b' suffix means file should be binary, and 't' means it is text. (Almost all layers should do the IO in binary mode, and ignore the b/t bits. The ":crlf" layer should be pushed to handle the distinction.)
If old is not "NULL" then this is a "PerlIO_reopen". Perl itself does not use this (yet?) and semantics are a little vague.
If fd not negative then it is the numeric file descriptor fd, which will be open in a manner compatible with the supplied mode string, the call is thus equivalent to "PerlIO_fdopen". In this case nargs will be zero. The file descriptor may have the close-on-exec flag either set or clear; it is the responsibility of the layer that takes ownership of it to get the flag into the correct state.
If nargs is greater than zero then it gives the number of arguments passed to "open", otherwise it will be 1 if for example "PerlIO_open" was called. In simple cases SvPV_nolen(*args) is the pathname to open.
If a layer provides "Open()" it should normally call the "Open()" method of next layer down (if any) and then push itself on top if that succeeds. "PerlIOBase_open" is provided to do exactly that, so in most cases you don't have to write your own "Open()" method. If this method is not defined, other layers may have difficulty pushing themselves on top of it during open.
If "PerlIO_push" was performed and open has failed, it must "PerlIO_pop" itself, since if it's not, the layer won't be removed and may cause bad problems.
Returns "NULL" on failure.
IV (*Binmode)(pTHX_ PerlIO *f);
Optional. Used when ":raw" layer is pushed (explicitly or as a result of binmode(FH)). If not present layer will be popped. If present should configure layer as binary (or pop itself) and return 0. If it returns -1 for error "binmode" will fail with layer still on the stack.
SV * (*Getarg)(pTHX_ PerlIO *f, CLONE_PARAMS *param, int flags);
Optional. If present should return an SV * representing the string argument passed to the layer when it was pushed. e.g. ":encoding(ascii)" would return an SvPV with value "ascii". (param and flags arguments can be ignored in most cases)
"Dup" uses "Getarg" to retrieve the argument originally passed to "Pushed", so you must implement this function if your layer has an extra argument to "Pushed" and will ever be "Dup"ed.
IV (*Fileno)(pTHX_ PerlIO *f);
Returns the Unix/Posix numeric file descriptor for the handle. Normally "PerlIOBase_fileno()" (which just asks next layer down) will suffice for this.
Returns -1 on error, which is considered to include the case where the layer cannot provide such a file descriptor.
PerlIO * (*Dup)(pTHX_ PerlIO *f, PerlIO *o, CLONE_PARAMS *param, int flags);
XXX: Needs more docs.
Used as part of the "clone" process when a thread is spawned (in which case param will be non-NULL) and when a stream is being duplicated via '&' in the "open".
Similar to "Open", returns PerlIO* on success, "NULL" on failure.
SSize_t (*Read)(pTHX_ PerlIO *f, void *vbuf, Size_t count);
Basic read operation.
Typically will call "Fill" and manipulate pointers (possibly via the API). "PerlIOBuf_read()" may be suitable for derived classes which provide "fast gets" methods.
Returns actual bytes read, or -1 on an error.
SSize_t (*Unread)(pTHX_ PerlIO *f, const void *vbuf, Size_t count);
A superset of stdio's "ungetc()". Should arrange for future reads to see the bytes in "vbuf". If there is no obviously better implementation then "PerlIOBase_unread()" provides the function by pushing a "fake" "pending" layer above the calling layer.
Returns the number of unread chars.
SSize_t (*Write)(PerlIO *f, const void *vbuf, Size_t count);
Basic write operation.
Returns bytes written or -1 on an error.
IV (*Seek)(pTHX_ PerlIO *f, Off_t offset, int whence);
Position the file pointer. Should normally call its own "Flush" method and then the "Seek" method of next layer down.
Returns 0 on success, -1 on failure.
Off_t (*Tell)(pTHX_ PerlIO *f);
Return the file pointer. May be based on layers cached concept of position to avoid overhead.
Returns -1 on failure to get the file pointer.
IV (*Close)(pTHX_ PerlIO *f);
Close the stream. Should normally call "PerlIOBase_close()" to flush itself and close layers below, and then deallocate any data structures (buffers, translation tables, ...) not held directly in the data structure.
Returns 0 on success, -1 on failure.
IV (*Flush)(pTHX_ PerlIO *f);
Should make stream's state consistent with layers below. That is, any buffered write data should be written, and file position of lower layers adjusted for data read from below but not actually consumed. (Should perhaps "Unread()" such data to the lower layer.)
Returns 0 on success, -1 on failure.
IV (*Fill)(pTHX_ PerlIO *f);
The buffer for this layer should be filled (for read) from layer below. When you "subclass" PerlIOBuf layer, you want to use its _read method and to supply your own fill method, which fills the PerlIOBuf's buffer.
Returns 0 on success, -1 on failure.
IV (*Eof)(pTHX_ PerlIO *f);
Return end-of-file indicator. "PerlIOBase_eof()" is normally sufficient.
Returns 0 on end-of-file, 1 if not end-of-file, -1 on error.
IV (*Error)(pTHX_ PerlIO *f);
Return error indicator. "PerlIOBase_error()" is normally sufficient.
Returns 1 if there is an error (usually when "PERLIO_F_ERROR" is set), 0 otherwise.
void (*Clearerr)(pTHX_ PerlIO *f);
Clear end-of-file and error indicators. Should call "PerlIOBase_clearerr()" to set the "PERLIO_F_XXXXX" flags, which may suffice.
void (*Setlinebuf)(pTHX_ PerlIO *f);
Mark the stream as line buffered. "PerlIOBase_setlinebuf()" sets the PERLIO_F_LINEBUF flag and is normally sufficient.
STDCHAR * (*Get_base)(pTHX_ PerlIO *f);
Allocate (if not already done so) the read buffer for this layer and return pointer to it. Return NULL on failure.
Size_t (*Get_bufsiz)(pTHX_ PerlIO *f);
Return the number of bytes that last "Fill()" put in the buffer.
STDCHAR * (*Get_ptr)(pTHX_ PerlIO *f);
Return the current read pointer relative to this layer's buffer.
SSize_t (*Get_cnt)(pTHX_ PerlIO *f);
Return the number of bytes left to be read in the current buffer.
void (*Set_ptrcnt)(pTHX_ PerlIO *f, STDCHAR *ptr, SSize_t cnt);
Adjust the read pointer and count of bytes to match "ptr" and/or "cnt". The application (or layer above) must ensure they are consistent. (Checking is allowed by the paranoid.)
To check that a PerlIO* is valid use PerlIOValid(PerlIO *f). (All this does is really just to check that the pointer is non-NULL and that the pointer behind that is non-NULL.)
PerlIOBase(PerlIO *f) returns the "Base" pointer, or in other words, the "PerlIOl*" pointer.
PerlIOSelf(PerlIO* f, type) return the PerlIOBase cast to a type.
Perl_PerlIO_or_Base(PerlIO* f, callback, base, failure, args) either calls the callback from the functions of the layer f (just by the name of the IO function, like "Read") with the args, or if there is no such callback, calls the base version of the callback with the same args, or if the f is invalid, set errno to EBADF and return failure.
Perl_PerlIO_or_fail(PerlIO* f, callback, failure, args) either calls the callback of the functions of the layer f with the args, or if there is no such callback, set errno to EINVAL. Or if the f is invalid, set errno to EBADF and return failure.
Perl_PerlIO_or_Base_void(PerlIO* f, callback, base, args) either calls the callback of the functions of the layer f with the args, or if there is no such callback, calls the base version of the callback with the same args, or if the f is invalid, set errno to EBADF.
Perl_PerlIO_or_fail_void(PerlIO* f, callback, args) either calls the callback of the functions of the layer f with the args, or if there is no such callback, set errno to EINVAL. Or if the f is invalid, set errno to EBADF.
The perlio.c and perliol.h in the Perl core implement the "unix", "perlio", "stdio", "crlf", "utf8", "byte", "raw", "pending" layers, and also the "mmap" and "win32" layers if applicable. (The "win32" is currently unfinished and unused, to see what is used instead in Win32, see "Querying the layers of filehandles" in PerlIO .)
PerlIO::encoding, PerlIO::scalar, PerlIO::via in the Perl core.
PerlIO::gzip and APR::PerlIO (mod_perl 2.0) on CPAN.
PerlIO::via::QuotedPrint in the Perl core and PerlIO::via::* on CPAN.
If you are creating a PerlIO layer, you may want to be lazy, in other words, implement only the methods that interest you. The other methods you can either replace with the "blank" methods
PerlIOBase_noop_ok PerlIOBase_noop_fail
(which do nothing, and return zero and -1, respectively) or for certain methods you may assume a default behaviour by using a NULL method. The Open method looks for help in the 'parent' layer. The following table summarizes the behaviour:
method behaviour with NULL Clearerr PerlIOBase_clearerr Close PerlIOBase_close Dup PerlIOBase_dup Eof PerlIOBase_eof Error PerlIOBase_error Fileno PerlIOBase_fileno Fill FAILURE Flush SUCCESS Getarg SUCCESS Get_base FAILURE Get_bufsiz FAILURE Get_cnt FAILURE Get_ptr FAILURE Open INHERITED Popped SUCCESS Pushed SUCCESS Read PerlIOBase_read Seek FAILURE Set_cnt FAILURE Set_ptrcnt FAILURE Setlinebuf PerlIOBase_setlinebuf Tell FAILURE Unread PerlIOBase_unread Write FAILURE FAILURE Set errno (to EINVAL in Unixish, to LIB$_INVARG in VMS) and return -1 (for numeric return values) or NULL (for pointers) INHERITED Inherited from the layer below SUCCESS Return 0 (for numeric return values) or a pointer
"perlio" over "unix" provides a complete replacement for stdio as seen via PerlIO API. This is the default for USE_PERLIO when system's stdio does not permit perl's "fast gets" access, and which do not distinguish between "O_TEXT" and "O_BINARY".
In addition perlio.c also provides a number of "PerlIOBase_xxxx()" functions which are intended to be used in the table slots of classes which do not need to do anything special for a particular method.
use PerlIO 'layer';
Where layer is the unknown layer. PerlIO.pm will then attempt to:
require PerlIO::layer;
If after that process the layer is still not defined then the "open" will fail.
The following extension layers are bundled with perl:
use Encoding;
makes this layer available, although PerlIO.pm "knows" where to find it. It is an example of a layer which takes an argument as it is called thus:
open( $fh, "<:encoding(iso-8859-7)", $pathname );
open( $fh, "+<:scalar", \$scalar );
When a handle is so opened, then reads get bytes from the string value of $scalar, and writes change the value. In both cases the position in $scalar starts as zero but can be altered via "seek", and determined via "tell".
Please note that this layer is implied when calling open() thus:
open( $fh, "+<", \$scalar );
use PerlIO::via::StripHTML; open( my $fh, "<:via(StripHTML)", "index.html" );
See PerlIO::via for details.
How PerlIO_apply_layera fits in, where its docs, was it made public?
Currently the example could be something like this:
PerlIO *foo_to_PerlIO(pTHX_ char *mode, ...) { char *mode; /* "w", "r", etc */ const char *layers = ":APR"; /* the layer name */ PerlIO *f = PerlIO_allocate(aTHX); if (!f) { return NULL; } PerlIO_apply_layers(aTHX_ f, mode, layers); if (f) { PerlIOAPR *st = PerlIOSelf(f, PerlIOAPR); /* fill in the st struct, as in _open() */ st->file = file; PerlIOBase(f)->flags |= PERLIO_F_OPEN; return f; } return NULL; }
Probably give some hints on using SETERRNO() or pointers to where they can be found.

HERSHEY, Pa., Nov. 1, 2018 /PRNewswire/ -- Every year, rib fractures impact nearly 350,000 of the patients admitted to major trauma centers in the United States alone. SIG Medical's (www.sigmedical.net) revolutionary AdvantageRib technology which was developed at the Penn State College of Medicine, Milton S. Hershey Medical Center, is an intrathoracic, minimally-invasive procedure designed to effectively treat very painful rib fractures without the use of large, open incisions or continuous doses of opioid pain medications.
SIG Medical recently closed on a Series Seed Funding round comprised of private investors and Pennsylvania's largest early-stage investor, Ben Franklin Technology Partners of Central & Northern PA. The company will utilize the investments to accelerate the commercialization of its already FDA-approved products and to continue to develop innovative thoracic medical devices.
Continue Reading
AdvantageRib is a revolutionary alternative to traditional rib fixation systems.
John Sider, Director of Second Stage Funding with Ben Franklin, commented, "Our Ben Franklin team was impressed by the clear need for the innovative rib-repair device and significantly less invasive procedure SIG Medical has developed. Our seed investments, which are very competitively awarded, provide capital to develop the foundation to create high wage jobs at a growing, profitable business. We are proud to have SIG Medical as a member of our portfolio."
Dr. Christopher Towe, Clinical Assistant Professor of Surgery at Case Western Reserve University School of Medicine in Cleveland, recently presented his experience utilizing AdvantageRib at Harvard's Innovations in Chest Wall Surgery Course. "AdvantageRib is a clever system and I have had success with it. It's no longer necessary for a patient presenting with a rib fracture to be off work for two months or to depend solely on opioid painkillers to manage their discomfort."
"We are excited to have the support of world-class investors who recognize the opportunity to improve healthcare," said Ken Kremer, President and CEO of SIG Medical. "With AdvantageRib, everyone wins: Surgeons finally have what they have been asking for - an effective and less invasive way of treating rib fractures; payors have a solution that reduces healthcare spending; and patients get access to a procedure that radically improves their care. This investment will allow us to continue to innovate and accelerate our mission of bringing revolutionary treatment to hundreds of thousands of patients."

Package Management
Package
: A collection of files & configuration wrapped up in an easy-to-distribute wrapper.
Dependencies
: Packages that Applications are dependent on in order to actually work. (This can go up to even thousands of dependencies!)
Why simply copying & pasting a file isn't that great:
Package Managers
: Applications that accept your code, bundled up with some important metadata, and provide services like versioning, change-management, and even tracking how many projects are using your code.
A Command Line Interface
: Application you run locally that let's you dl & install/uninstall packages as needed.Registry
: Database of package information, tracking which are available at any time.npm is the de facto standard for Node.js packages.
Some Basic npm commands
npm
: show npm's help info & common commands.npm init
: set current project directory up for npm.npm install
: dl & install a package into your project.
-g
: flag to globally install the package on your entire system.npm install pack-overflow
.package.json
file to include pack-overflow
as a dependency and requests it from the registry.snode_modules
package-lock.json
file that includes where the package is located.require('pack-overflow')
in our project.Dependency Management
Imagine bread being a dependency of a sandwich, the bread itself has further dependencies such as flour, yeast, water.
Many package managers have the ability to resolve & correct dependency versions - they will compare all the packages used by an application and determine which versions are most compatible.
Dependencies are formatted as such:
"package-name": "semantic.version.numer"
Semantic Version Number
: lets the CLI know more about exactly which version of that package to grab.
Major Changes
: Considered breaking, will be incompatible with other major versions - like creating a sequel to a hit video game.Minor Changes
: Represent new features, i.e. adding a new level to a game.Patch Level Changes
: Fixing Bugs or Small Issues, such as fixing a typo in a video game.package-lock.json
: A lockfile
that contains every detail needed to identify the exact version of an npm package that's being used by an application.
Node Modules
: Folder/ Subdirectory where all your package dependencies are store.
Creating Version Ranges We can designate a range by adding some special characters in our version number.
asterisk
: Whatever the latest version is.>1.0.0
: Any version above major version 1.^1.0.0
: Any version in the 1.x.x range.~1.0.0
: Any patch version in the 1.0.x range.1.0.0
: Exactly version 1.0.0.
Semantic Versioning is npm's secret weapon for dependency management.
Keep in mind, while npm will help you manage your dependencies, it will not automatically keep them up to date! (Always make sure your applications are up to date with the latest patches of their dependencies!)
Using npm to manage npm
npm install -g npm@latest
Using npm to manage a project's dependencies
package name
: default: name of current folder.version
: default: 1.0.0.description
: Necessary if you're going to publish your package.entry point
: Entry point to our application.test command
: Used if you're going to write tests for your package.git repository
: Letting other devs find the git repo. associated with your package.keywords
: Used to help people find your package.author
: Kimi no nawa.license
: Default: ISC License.Finding Packages in the NPM Registry Because there are millions of packages in the npm registry, you can ask yourself a few questions:
Is the package being maintained?
npm packages when searched for on the website are sorted by popularity, quality, and maintenance.
npm will recursively download all dependencies of dependencies into the node_module folder.
.gitignore
file to the root of the project so the node_modules folder will not be tracked by Git.Use the require
function to import the installed package into Node.js.
Dependency Types npm keeps track of two types of dependencies in our package.json
file:
Dependencies
: Packages that your project needs in order to successfully run when in production.devDependencies
: The packages that are needed locally when doing development work on the project.There are three additional dependencies called peer dependencies, bundled dependencies, and optional dependencies.
–save-dev : flag used when installing a package to install it as a development dependency.
You can simply run npm install
on a project that has exisisting dependencies to update any packages.
If you want to uninstall a package just use npm uninstall "package-name"
If you want to update an existing package to a specific version you can use this syntax: npm install<EMAIL_ADDRESS>If you'd like to update all your packages with one command you can use npm update
Finding and fixing package security vulnerabilites
During an installation, if any vulnerabilities are found we can use npm audit
to generate a report to see severities:
In turn we can use npm audit fix
to attempt to fix any security vulnerabilites - this will only remedy if a fix is available on a minor/patch version.
There is a strong option npm audit fix --force
that will fix your package with a major version - which might break your code - use with caution!
npm start
.npm run -custom script-

One of pro surfing's great individuals, Pauline Menzcer won the 1988 world amateur and 1993 professional crowns, took out events in every tour leg, gained the nickname "Naughty Pauls" and fought an incredible lifelong duel with crippling rheumatoid arthritis -- all without attracting the serious attention of a major sponsor. This might make another surfer bitter, but it only draws a mocking grin to Menzcer's freckled noggin. It's been a long time since she fit any mold.
Born in Sydney, Australia, Menzcer raised the ante in the women's pro scene of the late '80s and kept the hammer down on the likes of Lisa Andersen, Pam Burridge and Layne Beachley throughout the '90s. She learned to surf at Australia's great city break, Bondi, and worked up a strong high-energy approach that popped a few egos in Pro-World and even pulled a few hoots from the male pros -- a rare feat, then and now. Speed and snap were key to her early victories in French and Australian beachbreaks.
Watching her perform, it was difficult to imagine its flip side -- hours of agony from the arthritis. She pushed through it during competition, but other times, it hurt just to move her fingers. Eventually, Menzcer gained some control over the affliction through a rigorous diet.
She narrowly lost a world title race to Wendy Botha in 1991, but wrecked 1993 for everyone else by making half the finals and winning half of them. In that year, her only income -- slightly more than $30,000 -- came from prize money. Money has never come easy to Menzcer: her family was anything but rich.
Even in the late '90s, she took a tent on tour and slept in friends' backyards. Small, fiery and immensely likable, she pulls this kind of thing with relative ease. Off tour, she lives at Byron Bay in northern New South Wales, Australia. -- Nick Carroll


I choose really a simply machine to analize. Electronic claw arcade game also known as claw crane. This machine invite people to play with it. Once the coin is inside of it, you have 30 seconds to grab one of the items shown in the showcase with the help of a mechanical claw. If you win you will get a “valuable” object otherwise you will just lose your money.
The components of this arcade are: clear case, time display, button to grab, joystick, claw in a XY car and awards.
The clear cubed case allows users to get a notion of spaciality and use the joystick in order to move the car and the claw to any desire point in the highest plane of the case. Once the user decided it is the correct location, he/she press the button which triggers the claw to get down and close. The claw is always gonna return to its initial position and then open. If you grab something you will have it through a dispenser in the lower part of the machine.
Users tend to see the position of the objects and the claw on the X and Z axes (ground axes) in order to align them and get better chances. Besides, it is really common to try first with the higher objects, which are closer and more free.
It is important to point this sort of machines are well known worldwide which means the learning curve in every play is short no matter how different the design is. However, every configuration differs from each other, which can be make the task easier or not. In order to grab anything there are many variables to consider information about several features from position, weight to torque which this machine is not giving out. This could be seen as an example of a machine that gives a really little feedback to its users which is the whole idea. Let’s imagine a claw crane with extraodinary feedback capabilities. In that case, this machine would deliver information about the position, claw strength and aperture, the motion speed, the pick up strength, object’s size, weight and so on. This task would be as intuitive as grab something with our bare hands, which means everyone will win in a game without difficulty level. Bad deal!
This machine has low interactivity on purpose to challenge their users in order to get money. Almost as a Casino where the variables are many and the users feel more lucky than the faith. Win in those cases is possible, but really difficult.


Couchbase PHP Release Notes and Archives
SDK Installation
Installing on Linux-like systems
Before installing the PHP SDK, you must install the C SDK; version 2.9.0 or higher is required for 2.4.7.
After installing the C SDK, install the PHP SDK through your PHP distribution’s pecl command:
$ pecl install couchbase
Installing on Microsoft Windows
When using Microsoft Windows, instead of using PECL, download a pre-built binary matching your environment. You may also download the source for the SDK and build it directly in your environment if you have a complete build toolchain.
| Platform | x86 | x64 |
|---|---|---|
PHP 7.1 VC14 NTS |
||
PHP 7.1 VC14 ZTS |
||
PHP 7.0 VC14 NTS |
||
PHP 7.0 VC14 ZTS |
||
PHP 5.6 VC11 NTS |
||
PHP 5.6 VC11 ZTS |
Since release 2.3.3, by default binaries for Windows do not require php_igbinary.dll
to be installed. If you still need it as Couchbase serializer, you can rebuild binaries from source, or use the following binaries
| Platform | x86 | x64 |
|---|---|---|
PHP 7.1 VC14 NTS |
||
PHP 7.1 VC14 ZTS |
||
PHP 7.0 VC14 NTS |
||
PHP 7.0 VC14 ZTS |
||
PHP 5.6 VC11 NTS |
||
PHP 5.6 VC11 ZTS |
Post Installation for All Platforms
Once the PHP SDK has been installed, you need to specify that the PHP interpreter should load the Couchbase SDK as an extension. To do this:
-
Locate your php.ini file. This can be done using the command
php --ini
$ php --ini Configuration File (php.ini) Path: /usr/local/etc/php/7.0 Loaded Configuration File: /usr/local/etc/php/7.0/php.ini Scan for additional .ini files in: /usr/local/etc/php/7.0/conf.d Additional .ini files parsed: (none)
-
Insert a line in the php.ini file specifying the extension to be loaded; this should be in the
[PHP]
section. If you don’t know where that is, simply search for existing commented or uncommentedextension=
entries in the file. Note that the line differs for Linux/Mac OS from Microsoft Windows.
extension=couchbase.so
extension=couchbase.dll
Note on Extension Dependencies
If the igbinary extension is available at the time the Couchbase PHP extension is built, it will be built with support for igbinary
serialization. If that extension is not available at build time, later when loading the extension you may see a warning:
[cb,WARN] (pcbc/ext L:383) igbinary serializer is not found
This warning is safe to ignore if you are not planning to use igbinary serialization in your application.

Version 2.4.0 (5 September 2017)
This release contains internal improvements, as well as new features. Note, that minimum version of libcouchbase required is 2.8.0. Also from this version we drop support of PHP runtime older than 5.6.
New Features
-
PCBC-505: Enable error maps. This feature allows the server to control how the clients handle error codes, for example automatic retrying.
-
PCBC-499: Expose more query options on N1QL query for advanced tuning query performance. See documentation for methods scanCap, pipelineBatch, pipelineCap, maxParallelism, and readonly on \Couchbase\N1qlQuery class.
-
PCBC-485: Expose enhanced error messages. The server might fill new properties of the error (\Couchbase\Exception class instance): "context" (additional text description of the error) and "ref" (reference id in the server logs).
Version 2.3.4 (19 July 2017)
This release contains internal improvements, as well as new features. Note, that minimum version of libcouchbase required is 2.7.6.
New Features
-
PCBC-495: Update user management APIs: added method to fetch user by name, and support for authentication domains.
Improvements
-
PCBC-478: Add tests for Error Map using CouchbaseMock
Version 2.3.3 (31 May 2017)
This release contains internal improvements, as well as new features. Note, that minimum version of libcouchbase required is 2.7.5.
New Features
-
PCBC-475: Add support for term range query and geo search queries in full text search.
-
PCBC-468: Add support for user CRUD in ClusterManager (RBAC feature of upcoming Couchbase Server 5). Read more about it in the server documentation.
-
PCBC-489: Add shortcut for PasswordAuthenticator as Cluster→authenticateAs($username, $password).
-
PCBC-472: Expose setting accessor for configuration polling interval. Accessible as Bucket→configPollInterval. With Couchbase Server 5 it will allow faster failover.
Version 2.3.2 (2 May 2017)
This release contains internal improvements, as well as new features. Note, that minimum version of libcouchbase required is 2.7.4.
Known Issues
-
PCBC-487: \Couchbase\N1qlQuery→adhoc() method actually worked in reversed way. When this parameter set to true (which is default), the library creates prepared statement, and skip it otherwise. Releases after 2.3.3 will fix this behaviour and really use adhoc queries by default.
New Features
-
PCBC-451: Add RBAC support in \Couchbase\PasswordAuthenticator class (Couchbase Server 5.x feature). Read more about it in the blog Authentication and Authorization with RBAC.
$authenticator = new \Couchbase\PasswordAuthenticator(; $authenticator->username('john')->password('s3cret'); $cluster = new \Couchbase\Cluster('couchbase://<IP_ADDRESS>'); $cluster->authenticate($authenticator);
-
PCBC-440: Add experimental support of extended attributes for subdocument operations. This might be useful for storing application-specific information, which should not be treated as document contents.
$b->upsert('doc1', ['foo' => 'bar']); $b->mutateIn('doc1') ->upsert('app.created_by', ['name' => 'John Doe', 'role' => 'DB administrator'], ['xattr' => true, 'createPath' => true]) ->execute(); $result = $b->lookupIn('doc1') ->get('app.created_by', ['xattr' => true, 'createPath' => true]) ->execute(); $result->value[0]['value']; // ['name' => 'John Doe', 'role' => 'DB administrator']
-
PCBC-453: Verify that ClusterManager supports ephemeral buckets. This is new type of buckets accessible in Couchbase Server 5, which basically enhanced Memcached-style bucket with replication, failover and other Couchbase bucket features.
$cluster = new \Couchbase\Cluster('couchbase://<IP_ADDRESS>'); $cluster->manager()->createBucket('ephemeralTest', ['bucketType' => 'ephemeral']);
Fixed Issues
-
PCBC-473: Fix incorrect bucket reference copy in subdocument mutation/lookup builders, which might lead to segfault.
-
PCBC-474: Fix segfault when using ViewQuery::keys().
-
PCBC-476: Do not call destructors on unintialized ZVALs. Fixes possible segfaults with view queries on PHP 5.x.
-
PCBC-477: Lookup JsonSerializable interface in run time, instead of compile time using php_json_serializable_ce symbol. This fixes support of some 5.4-5.5 builds.
-
PCBC-479: Do not allow to create objects in invalid state. For example Cluster might return an instance, and only show PHP warning on invalid arguments.
-
PCBC-481: Fix Bucket→counter() without specifying delta value results in null pointer dereference.
-
PCBC-482: mapSize/setExists/setRemove methods of Bucket did not check if 'get' sub-request had thrown exception. This cause segfault, if operation executed on keys which do not exist.
Version 2.3.1 (5 April 2017)
This release contains internal improvements, as well as new features. Note, that minimum version of libcouchbase required is 2.7.3.
Fixed Issues
-
PCBC-459: Restore \Couchbase\Bucket::unlock() method, which has been lost in refactoring.
-
PCBC-460: Prefer managed strings to persistent when storing document values.
-
PCBC-461: Deallocate intermediate results when using encoder compression
-
PCBC-462: Replace new lines in log entries with space.
-
PCBC-464: Fix NumericRangeFacet with NULL boundary on PHP 5.4.
-
PCBC-463: Fix incorrect reference counting on Search API. (might lead to segfaults and leaks).
-
PCBC-465: Check encoded ViewQuery before sending to libcouchbase.
-
PCBC-467: Intermediate values in Datastructures API might leak. (e.g. result of internal "get" to find out size of the list).
-
PCBC-471: Fixed issue, when the library always use credentials for the first bucket in Authenticator.
New features
-
PCBC-469: Implement SearchQuery→sort() function to support sorting FTS results, which is accessible in Couchbase Server 4.6+.
-
PCBC-441: Add experimental support of Analytics query. Read more about Analytics Service at documentation site
Version 2.3.0 (7 March 2017)
This release contains internal improvements, as well as new features. Note, that minimum version of libcouchbase required is 2.7.2. This release does not depend on the PCS extension. All classes which were previously written in PHP are now implemented in the Zend C APIs. This means they do not require extra evaluation on module load or request initialization.
New features
-
PCBC-382: Implement cluster-level authentication using ClassicAuthenticator (see integration/CrossBucketN1qlQueryTest.php)
-
PCBC-383: Cross-bucket joins for N1QL queries (see see examples/api/couchbase.N1qlQuery.crossBucket.php)
-
PCBC-386: Implement Datastructures API: List, Set, Map and Queue (see Data Structures on the documentation site and tests/DatastructuresTest.php in the repository)
-
Improved connection management: connections are persistent by default, but the library tracks their liveliness and closes idle connections.
-
Migrate API to \Couchbase namespace. The old API is still available at the toplevel as aliases, see tests/AliasesTest.php)
-
Refresh API documentation, describe all input options, put everything into single file (see api/) , and make it available through PHPStorm (JetBrains/phpstorm-stubs#180)
Fixed Issues
-
PCBC-443: PCS dependency has been removed and all classes were rewritten using the Zend C API
Breaking change
With previous default the options were defined in the global variables $COUCHBASE_DEFAULT_ENCOPTS and $COUCHBASE_DEFAULT_DECOPTS. Starting with 2.3 if you are adjusting those defaults, this should now be done through INI variables couchbase.encoder.* and couchbase.decoder.*. The full list of the supported INI options with detailed description is in the API documentation.
Version 2.2.4 (26 December 2016)
This release contains bug fixes and performance improvements. Note, the minimum version of libcouchbase required is 2.6.1. This release depends on PCS extension.
Known Issues
-
PCBC-443: Installation issues with PCS Extension. Partially owing to a bug in PCS and partially owing to adding an additional dependency, the PCS Extension has been problemmatic. It will be removed in a future release. If this impacts your installation, use the 2.2.3 release.
Fixed Issues
-
PCBC-401: Embed PHP classes using PCS (PHP Code Service) extension 1.3.1. This fixes a performance issue, where the extension would spend time during each request to evaluate and load Couchbase classes written in PHP. The pecl/pcs extension has to be installed and loaded before loading couchbase SDK.
-
PCBC-439: Fix code which handles document compression flags, so a compressed document is not handled by a JSON decoder.
-

Backward-incompatible API changes since 2.1.0
-
CouchbaseBucket→query() accepts only 2 arguments, and query properties supposed to be set in query objects (CouchbaseN1qlQuery, CouchbaseViewQuery, CouchbaseSearchQuery instances).\ For 2.1.0:
$query = CouchbaseN1qlQuery::fromString("SELECT * FROM `travel-sample` WHERE city=$arg"); $bucket->query($query, array("arg" => "London"), true);
For 2.2.0:
$query = CouchbaseN1qlQuery::fromString("SELECT * FROM `travel-sample` WHERE city=$arg"); $query->namedParams(array("arg" => "London")); $bucket->query($query, true);
-
Return value of CouchbaseBucket→query() is always object, but the contents of the rows attribute still controlled by second argument to the method.\ For 2.1.0:
$query = CouchbaseN1qlQuery::fromString("SELECT * FROM `default` LIMIT 10"); // Rows as nested arrays $res = $bucket->query($query, NULL, true); foreach ($res as $row) { printf("%s\n", $row['default']['myprop']); } // Rows as objects $res = $bucket->query($query, NULL, false); foreach ($res as $row) { printf("%s\n", $row->default->myprop); }
For 2.2.0
// Rows as nested arrays $res = $bucket->query($query, true); foreach ($res->rows as $row) { printf("%s\n", $row['default']['myprop']); } // Rows as objects $res = $bucket->query($query, false); foreach ($res->rows as $row) { printf("%s\n", $row->default->myprop); }
This is done to allow inject additional meta information into result, and to have a way to extend result objects in the future. For example, this is how one can pull N1QL metrics from results:
$res = $bucket->query($query); printf("Query has been completed in %s and returned %d rows\n", $res->metrics['elapsedTime'], $res->metrics['resultCount']); //=> Query has been completed in 8.543433ms and returned 1 rows
Fixed Issues
-
PCBC-398: Expose methods for parameterized N1QL queries.
Version 2.2.0 Beta 3 (25 May 2016)
Fixed Issues
-
PCBC-395: Type checks incorrectly for booleans. This could lead to a CouchbaseException occurring when query results contain numbers instead of booleans.

Rotations and Angular Velocity
A rotation of a vector is a change which only alters the direction, not the length, of a vector. A rotation consists of a rotation axis and a rotation rate. By taking the rotation axis as a direction and the rotation rate as a length, we can write the rotation as a vector, known as the angular velocity vector \(\vec{\omega}\). We use the right-hand rule to describe the direction of rotation. The units of $\vec\omega$ are $\rm rad/s$ or ${}^\circ/s$.
Rotation axis: $\hat\imath$ $\hat\jmath$ $\hat{k}$ $\hat\imath + \hat\jmath$ $\hat\imath + \hat\jmath + \hat{k}$
Angular velocity vector $\vec\omega$. The direction of $\vec\omega$ is the axis of rotation, while the magnitude is the speed of rotation (positive direction given by the right-hand rule).
The Greek letter ω (lowercase omega) is the last letter of the Greek alphabet, leading to expressions such as “from alpha to omega” meaning “from start to end”. Omega literally means O-mega, meaning O-large, as capital Omega (written Ω) developed from capital Omicron (written Ο) by breaking the circle and turning up the edges. Omicron is literally O-micron, meaning O-small, and it is the ancestor of the Latin letter O that we use today in English.
| Α | α | alpha | Ι | ι | iota | Ρ | ρ | rho |
| Β | β | beta | Κ | κ | kappa | Σ | σ | sigma |
| Γ | γ | gamma | Λ | λ | lambda | Τ | τ | tau |
| Δ | δ | delta | Μ | μ | mu | Υ | υ | upsilon |
| Ε | ε | epsilon | Ν | ν | nu | Φ | φ | phi |
| Ζ | ζ | zeta | Ξ | ξ | xi | Χ | χ | chi |
| Η | η | eta | Ο | ο | omicron | Ψ | ψ | psi |
| Θ | θ | theta | Π | π | pi | Ω | ω | omega |
The Greek alphabet, shown above, was the first true alphabet, meaning that it has letters representing phonemes (basic significant sounds) and includes vowels as well as consonants. The Greek alphabet was was derived from the earlier Phoenician alphabet, which was probably the original parent of all alphabets. This shows that the idea of an alphabet is so non-obvious that it has only ever been invented once, and then always copied after that.
Vector derivatives and rotations
If a unit vector \(\hat{a}\) is rotating, then the angular velocity vector \(\vec{\omega}\) is defined so that:
Derivative of unit vectors.
\[\dot{\hat{a}} = \vec{\omega} \times \hat{a}\]
Derivative of general vectors.
\[\begin{aligned} \dot{\vec{a}} = \underbrace{\dot{a} \hat{a}}_{\operatorname{Proj}(\dot{\vec{a}}, \vec{a})} + \underbrace{\vec{\omega} \times \vec{a}}_{\operatorname{Comp}(\dot{\vec{a}}, \vec{a})} \end{aligned}\]
Using the same approach as #rvc-em we write $\vec{a} = a\hat{a}$ and differentiate this and use rkr-ew to find: \[\begin{aligned} \dot{\vec{a}} &= \frac{d}{dt} \big( a \hat{a} \big) \\ &= \dot{a} \hat{a} + a \dot{\hat{a}} \\ &= \dot{a} \hat{a} + a (\vec\omega \times \hat{a}) \\ &= \dot{a} \hat{a} + \vec\omega \times (a \hat{a}) \\ &= \dot{a} \hat{a} + \vec\omega \times \vec{a}. \end{aligned}\] Comparing this to #rvc-em shows that the two components are the projection and the complementary projection, respectively.
Derivative of constant-length vectors.
\[\dot{\vec{a}} = \vec{\omega} \times \vec{a} \qquad\text{if $\vec{a}$ is constant length}\]
This can be seen from the fact that $\dot{a} = 0$ if $a$ is constant (a fixed length vector), substituted into #rkr-ed.
Rotations in 2D
In 2D the angular velocity can be thought of as a scalar (positive for counter-clockwise, negative for clockwise). This scalar is just the out-of-plane component of the full angular velocity vector. We can draw the angular velocity as either a vector pointing out of the plane, or as a circle-arrow in the plane, which is simpler for 2D diagrams.
Show:
Comparison of the vector and scalar representations of $\vec\omega$ for 2D rotations.
In 2D the angular velocity scalar $\omega$ is simply the derivative of the rotation angle $\theta$ in the plane:
Magnitude $\omega$ is derivative of angle $\theta$ in 2D.
\[\omega = \dot\theta\]
Take $\hat{a}$ to be a unit vector rotating in the 2D $\hat\imath$–$\hat\jmath$ plane, making an angle of $\theta$ with the $x$-axis, as in Figure #rkr-f2. Then: \[\hat{a} = \cos\theta \,\hat\imath + \sin\theta \,\hat\jmath.\] Differentiating this expression gives: \[\dot{\hat{a}} = -\sin\theta \, \dot\theta \,\hat\imath + \cos\theta \,\dot\theta \,\hat\jmath.\] We now consider an angular velocity vector $\vec\omega$. Because the rotation is in the $\hat\imath$–$\hat\jmath$ plane, the angular velocity vector must be in the $\hat{k}$ direction. Thus $\vec\omega = \omega \hat{k}$. Now we can compute the derivative of $\hat{a}$ using #rkr-ew, giving: \[\begin{aligned} \dot{\hat{a}} &= \vec\omega \times \hat{a} \\ &= \omega\hat{k} \times \big( \cos\theta \,\hat\imath + \sin\theta \,\hat\jmath \big) \\ &= \omega \cos\theta \,(\hat{k} \times \hat\imath) + \omega \sin\theta \,(\hat{k} \times \hat\jmath) \\ &= \omega \cos\theta \,\hat\jmath + \omega \sin\theta \,(-\hat\imath) \\ &= - \omega \sin\theta \,\hat\imath + \omega \cos\theta \,\hat\jmath. \end{aligned}\] Comparing this expression to the earlier one for $\dot{\hat{a}}$ we see that $\omega = \dot\theta$.
The right-hand rule convention for angular velocities means that counter-clockwise rotations are positive, just like the usual angle direction convention.
Angular directions have long been considered to have magical or spiritual significance. In Britain the counterclockwise direction was once known as widdershins, and it was considered unlucky to travel around a church in a widdershins direction.
Interestingly, right-handed people tend to naturally draw circles in a counterclockwise direction, and clockwise drawing in right-handed children is an early warning sign for the later development of schizophrenia [Blau, 1977].

Rotations and vector “positions”
The fact that vectors don't have positions means that vector rotations are independent of where vectors are drawn, just like for derivatives.
Show:
Rotational motion of vectors which are drawn moving about. Note that the drawn position does not affect the angular velocity $\omega$ or the derivative vectors.
Properties of rotations
Rotations are rigid transformations, meaning that they keep constant all vector lengths and all relative vector angles. These facts are reflected in the following results, which all consider two vectors $\vec{a}$ and $\vec{b}$ that are rotating with angular velocity $\vec\omega$.
Derivative of rotating vector is orthogonal.
\[\dot{\vec{a}} \cdot \vec{a} = 0\]
Angle $\theta$ between rotating vectors is constant.
\[\theta = \cos^{-1}\left(\frac{\vec{b} \cdot \vec{a}}{b a}\right) = \text{constant}\]
We first consider the dot product $\vec{a} \cdot \vec{b}$ and show that this is not changing with time. We do this by using the scalar triple product formula #rvi-es to find: \[\begin{aligned} \frac{d}{dt} \big( \vec{a} \cdot \vec{b} \big) &= \dot{\vec{a}} \cdot \vec{b} + \vec{a} \cdot \dot{\vec{b}} \\ &= (\vec{\omega} \times \vec{a}) \cdot \vec{b} + \vec{a} \cdot (\vec{\omega} \times \vec{b}) \\ &= \vec{b} \cdot (\vec{\omega} \times \vec{a}) + \vec{b} \cdot (\vec{a} \times \vec{\omega}) \\ &= \vec{b} \cdot (\vec{\omega} \times \vec{a}) - \vec{b} \cdot (\vec{\omega} \times \vec{a}) \\ &= 0. \end{aligned}\] Now $\vec{a} \cdot \vec{b}$ is constant and the lengths $a$ and $b$ are constant, so the angle $\theta$ between the vectors must be constant.
Rotating vectors parallel to $\vec\omega$ are constant.
\[\dot{\vec{a}} = 0 \qquad \text{if $\vec{a}$ is rotating and parallel to $\vec\omega$}\]
From #rkr-el we know that the derivative is \[\dot{\vec{a}} = \vec\omega \times \vec{a},\] but the cross product is zero for parallel vectors, so this the derivative is zero.
Rodrigues’ rotation formula
Rodrigues’ rotation formula gives an explicit formula for a vector rotated by an angle about a given axis.
Rodrigues’ rotation formula for $\vec{a}$ rotated by $\theta$ about $\hat{b}$.
\[\operatorname{Rot}(\vec{a}; \theta, \hat{b}) = \vec{a} \cos\theta + (\hat{b} \times \vec{a}) \sin\theta + \hat{b} (\hat{b} \cdot \vec{a}) (1 - \cos\theta)\]
Assume \(\vec{a}\) is not parallel to \(\hat{b}\). Then let \(\vec{v} = \hat{b} \times \vec{a}\) and \(\vec{u} = \vec{v} \times \vec{b}\), so \(\hat{u}, \hat{v}, \hat{b}\) is a right-handed orthonormal basis. Take \(\phi\) to be the angle between \(\vec{a}\) and \(\hat{b}\). Then we do a rotation by \(\theta\) in the \(\hat{u}\)-\(\hat{v}\) plane:
\[\begin{aligned} \vec{a} &= a \sin\phi \,\hat{u} + a \cos\phi \,\hat{b} \\ \operatorname{Rot}(\vec{a};\theta,\hat{b}) &= a \cos\theta \sin\phi \,\hat{u} + a \sin\theta \sin\phi \,\hat{v} + a \cos\phi \,\hat{b}.\end{aligned}\]
Now we want to convert from the \(\hat{u},\hat{v},\hat{b}\) basis to write the rotated result in terms of \(\vec{a}, (\hat{b} \times \vec{a}), \hat{b}\). To do this, we need to work out what \(\hat{u},\hat{v},\hat{b}\) are in terms of these other vectors.
\[\begin{aligned} \hat{v} &= \frac{\hat{b} \times \vec{a}}{\|\hat{b} \times \vec{a}\|} = \frac{\hat{b} \times \vec{a}}{a \sin\phi} \\ \hat{u} &= \frac{\vec{v} \times \hat{b}}{\|\vec{v} \times \vec{b}\|} = \frac{\vec{v} \times \hat{b}}{a \sin\phi} = \frac{(\hat{b} \times \vec{a}) \times \hat{b}}{a \sin\phi} = \frac{\hat{b} \times (\vec{a} \times \hat{b})}{a \sin\phi} \\ &= \frac{\vec{a} - (\hat{b} \cdot \vec{a}) \hat{b}}{a \sin\phi} = \frac{1}{a \sin\phi} \vec{a} - \frac{\hat{b} \cdot \vec{a}}{a \sin\phi} \hat{b}.\end{aligned}\]
Substituting these into the rotated vector expression above gives
\[\begin{aligned} \operatorname{Rot}(\vec{a};\theta,\hat{b}) &= a \cos\theta \sin\phi \, \left( \frac{1}{a \sin\phi} \vec{a} - \frac{\hat{b} \cdot \vec{a}}{a \sin\phi} \hat{b} \right) \\ & \qquad + a \sin\theta \sin\phi \, \left( \frac{\hat{b} \times \vec{a}}{a \sin\phi} \right) + a \cos\phi \,\hat{b} \\ &= \cos\theta \,\vec{a} - \cos\theta \,(\hat{b} \cdot \vec{a}) \,\hat{b} + \sin\theta \,(\hat{b} \times \vec{a}) + a\cos\theta \,\hat{b} \\ &= \cos\theta \,\vec{a} + (1 - \cos\theta) (\hat{b} \cdot \vec{a}) \,\hat{b} + \sin\theta \,(\hat{b} \times \vec{a}).\end{aligned}\]


Galaxy's CAF Journey Ended By Nigerian Giants
by Soccer LadumaCAF Confederation Cup
Result: TS Galaxy 1-2 Enyimba (Enyimba won 4-1 on agg.)
Date: 03 November 2019
Venue: Mbombela Stadium
TS Galaxy's CAF Confederation Cup journey came to an end on Sunday, after losing 4-1 on aggregate to Nigerian outfit Enyimba in the play-off round.
The Nedbank Cup champions entered the encounter with a lot of work to do after suffering a 2-0 loss to Enyimba in Nigeria two weeks ago.
Galaxy have enjoyed a good record at home in the Confederation Cup this season, having registered two wins without conceding against the likes of St Louis Suns and CNaPS Sport.
Dan Malesela's troops were finding it tough to break down the Nigerian Football Premier League outfit and had to wait until the 30th minute for an opening as Tshepo Chaine fired wide from close range.
Unfortunately for the hosts, that proved to be the only real effort of the opening stanza as frustration began to build for Galaxy at the Mbombela Stadium.
Despite looking livelier in the second half, it was Enyimba who got the opening goal in the second leg thanks to a 76th minute strike from Daniel Darkwah to make it 3-0 on aggregate.
The Nigerians doubled the lead with eight minutes remaining in the second, with Martins Usule getting his name on the score-sheet as his side secured a spot in the group stage while Galaxy bow out.
Galaxy did managed to pull a goal back in the latter stages of second stanza through Terrence Mashego, but it was nothing more than a consolation as Enyimba triumphed 2-1 on the day and 4-1 on aggregate tp secure a spot in the group stages.


While building website with Pillar using academic
archetype, sometimes you may want to change some elements. Then, in this tutorial, we are explaining how academic
archetype is working and how to modify it.
academic
archetype is a Pillar archetype especially for building static websites (personal ones or for projects) in Pillar.
Let's explain the global presentation of an archetype. It is a directory containing other directories like:
For academic archetype, we have something like that
By default, this file looks like this
Each input file is representing a menu (page) of your website. Each file needs to contain at least one title (H1 ! or H2 !!). The Menu builder is just taking the first title founded in a file as menu label. For these kinds of websites with academic
you can't have submenus, or you will have to modify the menu builder. Then if you want to modify the menu, just modify this template by adding or removing an input annotation.
academic
archetype is installed by this commandThis command is just copying files from archetype to project:
_support
directory under the project folder with the same structure as in the archetype one's.So after this command, your project looks like this
By default, the main.mustache
is the template file used for generating pages. This template is a classic with a profile on the left and page contents on the right.
You can change template for certain files. To achieve that, add this code at the head of that file.
So, that page will be generated with a different template file. In this case, the page won't contain a profile at the left, only contents on the page. When you want to use your own template, just place it at this location "_support/templates/html".
If you want to completely change the mustache template for all your pages, you can directly specify the template in pillar.conf
.
blog.mustache
template propose a disqus comment integration. It allows people to comment on your articles.fixed_profile.mustache
presents a fixed profile on the left. Even if you scroll down the page, the profile is always visible on the left.
The main included css file is styles.css
. This file contains principal css rules used in the template. If you are interested in touching the css, you can check for that file.


Kombi fire accident kills 8 in Zim
Eight people died while two others sustained minor injuries last night when a commuter omnibus heading to Kanyemba from Harare collided with a lorry and burst into flames in Concession, Mazowe District.
The eight included the driver of the commuter omnibus. Oshia Njenge (22) was the only survivor when the commuter omnibus rammed into a Toyota Dyna truck. The 22-year-old survivor recounted the moments leading up to the horrific crash.
“Ndirikungonzwa kurwadziwa nekurasikirwa kwakaitwa vanhu nehupenyu (I am hurt by the way people perished in the accident),” said Njenge.
Eyewitnesses interviewed at the scene said they were unable to help after flammable substances in the commuter omnibus fueled the fire.
Mashonaland Central Acting Provincial Development Coordinator, Cosmas Chiringa confirmed the incident.
He appealed to public service vehicles to desist from carrying flammable substances on board.
The injured were treated and discharged while 7 of the deceased have been identified after the bodies were taken to Concession Hospital Mortuary. Names are being withheld until their next of kin have been informed. One body is yet to be identified.
