public class FileProvider
extends ContentProvider
ContentProvider
that facilitates secure sharing
of files associated with an app by creating a content://
Uri
for a file
instead of a file:///
Uri
.
A content URI allows you to grant read and write access using
temporary access permissions. When you create an Intent
containing
a content URI, in order to send the content URI
to a client app, you can also call Intent.setFlags()
to add
permissions. These permissions are available to the client app for as long as the stack for
a receiving android.app.Activity
is active. For an Intent
going to a
android.app.Service
, the permissions are available as long as the
android.app.Service
is running.
In comparison, to control access to a file:///
Uri
you have to modify the
file system permissions of the underlying file. The permissions you provide become available to
any app, and remain in effect until you change them. This level of access is
fundamentally insecure.
The increased level of file access security offered by a content URI makes FileProvider a key part of Android's security infrastructure.
This overview of FileProvider includes the following topics:
Since the default functionality of FileProvider includes content URI generation for files, you
don't need to define a subclass in code. Instead, you can include a FileProvider in your app
by specifying it entirely in XML. To specify the FileProvider component itself, add a
<provider>
element to your app manifest. Set the android:name
attribute to
android.support.v4.content.FileProvider
. Set the android:authorities
attribute to a URI authority based on a domain you control; for example, if you control the
domain mydomain.com
you should use the authority
com.mydomain.fileprovider
. Set the android:exported
attribute to
false
; the FileProvider does not need to be public. Set the
android:grantUriPermissions attribute to true
, to allow you
to grant temporary access to files. For example:
<manifest> ... <application> ... <provider android:name="android.support.v4.content.FileProvider" android:authorities="com.mydomain.fileprovider" android:exported="false" android:grantUriPermissions="true"> ... </provider> ... </application> </manifest>
If you want to override any of the default behavior of FileProvider methods, extend
the FileProvider class and use the fully-qualified class name in the android:name
attribute of the <provider>
element.
<paths>
element.
For example, the following paths
element tells FileProvider that you intend to
request content URIs for the images/
subdirectory of your private file area.
<paths xmlns:android="http://schemas.android.com/apk/res/android"> <files-path name="my_images" path="images/"/> ... </paths>
The <paths>
element must contain one or more of the following child elements:
<files-path name="name" path="path" />
files/
subdirectory of your app's internal storage
area. This subdirectory is the same as the value returned by Context.getFilesDir()
.
<external-path name="name" path="path" />
Context.getExternalFilesDir()
returns the
files/
subdirectory of this this root.
<cache-path name="name" path="path" />
getCacheDir()
.
These child elements all use the same attributes:
name="name"
path
attribute.
path="path"
name
attribute is a URI path
segment, the path
value is an actual subdirectory name. Notice that the
value refers to a subdirectory, not an individual file or files. You can't
share a single file by its file name, nor can you specify a subset of files using
wildcards.
You must specify a child element of <paths>
for each directory that contains
files for which you want content URIs. For example, these XML elements specify two directories:
<paths xmlns:android="http://schemas.android.com/apk/res/android"> <files-path name="my_images" path="images/"/> <files-path name="my_docs" path="docs/"/> </paths>
Put the <paths>
element and its children in an XML file in your project.
For example, you can add them to a new file called res/xml/file_paths.xml
.
To link this file to the FileProvider, add a
<meta-data> element
as a child of the <provider>
element that defines the FileProvider. Set the
<meta-data>
element's "android:name" attribute to
android.support.FILE_PROVIDER_PATHS
. Set the element's "android:resource" attribute
to @xml/file_paths
(notice that you don't specify the .xml
extension). For example:
<provider android:name="android.support.v4.content.FileProvider" android:authorities="com.mydomain.fileprovider" android:exported="false" android:grantUriPermissions="true"> <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/file_paths" /> </provider>
To share a file with another app using a content URI, your app has to generate the content URI.
To generate the content URI, create a new File
for the file, then pass the File
to getUriForFile()
. You can send the content URI
returned by getUriForFile()
to another app in an
android.content.Intent
. The client app that receives the content URI can open the file
and access its contents by calling
ContentResolver.openFileDescriptor
to get a ParcelFileDescriptor
.
For example, suppose your app is offering files to other apps with a FileProvider that has the
authority com.mydomain.fileprovider
. To get a content URI for the file
default_image.jpg
in the images/
subdirectory of your internal storage
add the following code:
File imagePath = new File(Context.getFilesDir(), "images"); File newFile = new File(imagePath, "default_image.jpg"); Uri contentUri = getUriForFile(getContext(), "com.mydomain.fileprovider", newFile);As a result of the previous snippet,
getUriForFile()
returns the content URI
content://com.mydomain.fileprovider/my_images/default_image.jpg
.
getUriForFile()
, do one of the following:
Context.grantUriPermission(package, Uri, mode_flags)
for the content://
Uri
, using the desired mode flags. This grants temporary access permission for the
content URI to the specified package, according to the value of the
the mode_flags
parameter, which you can set to
Intent#FLAG_GRANT_READ_URI_PERMISSION
, Intent#FLAG_GRANT_WRITE_URI_PERMISSION
or both. The permission remains in effect until you revoke it by calling
revokeUriPermission()
or until the device
reboots.
Intent
by calling setData()
.
Intent.setFlags()
with either
Intent#FLAG_GRANT_READ_URI_PERMISSION
or
Intent#FLAG_GRANT_WRITE_URI_PERMISSION
or both.
Intent
to
another app. Most often, you do this by calling
setResult()
.
Permissions granted in an Intent
remain in effect while the stack of the receiving
android.app.Activity
is active. When the stack finishes, the permissions are
automatically removed. Permissions granted to one android.app.Activity
in a client
app are automatically extended to other components of that app.
There are a variety of ways to serve the content URI for a file to a client app. One common way
is for the client app to start your app by calling
startActivityResult()
,
which sends an Intent
to your app to start an android.app.Activity
in your app.
In response, your app can immediately return a content URI to the client app or present a user
interface that allows the user to pick a file. In the latter case, once the user picks the file
your app can return its content URI. In both cases, your app returns the content URI in an
Intent
sent via setResult()
.
You can also put the content URI in a android.content.ClipData
object and then add the
object to an Intent
you send to a client app. To do this, call
Intent.setClipData()
. When you use this approach, you can
add multiple android.content.ClipData
objects to the Intent
, each with its own
content URI. When you call Intent.setFlags()
on the Intent
to set temporary access permissions, the same permissions are applied to all of the content
URIs.
Note: The Intent.setClipData()
method is
only available in platform version 16 (Android 4.1) and later. If you want to maintain
compatibility with previous versions, you should send one content URI at a time in the
Intent
. Set the action to Intent#ACTION_SEND
and put the URI in data by calling
setData()
.

F-35 unit from Utah base begins deployment to Middle East
HILL AIR FORCE BASE, Utah (AP) - Another Hill Air Force Base squadron equipped with F-35 fighters has left on a combat deployment for the Middle East.
The Standard-Examiner reports that the 34th Fighter Squadron with personnel drawn from active-duty and reserve units at Hill left recently for Al Dhafra Air Base, in the United Arab Emirates.
Col. Steven Behmer, commander of the 388th Fighter Wing, said the squadron consists of pilots and other personnel from the 34th Fighter Squadron and from a reserve unit, the 466th Fighter Squadron.
Personnel and jets from Hill’s 4th Fighter Squadron returned recently from a six-month deployment to the same region.

module BatPrintexc:{
..}
let pass : ('a => 'b) => 'a => 'b
Printexc.pass fn x
applies fn
to x
and returns the result.
If the evaluation of fn x
raises any exception, the name of the
exception is printed on standard error output, and the exception
is raised again. The typical use is to catch and report
exceptions that escape a function application. This function is a
renamed version of Printexc.print
from stdlib.let catch : ('a => 'b) => 'a => 'b
Printexc.catch fn x
is similar to Printexc.print
, but aborts
the program with exit code 2 after printing the uncaught exception.
This function is deprecated: the runtime system is now able to
print uncaught exceptions as precisely as Printexc.catch
does.
Moreover, calling Printexc.catch
makes it harder to track the
location of the exception using the debugger or the stack backtrace
facility. So, do not use Printexc.catch
in new code.let to_string : exn => string
Printexc.to_string e
returns a string representation of the
exception e
.let print_backtrace : BatInnerIO.output 'a => unit
print_backtrace oc
Prints the an exception backtrace on the
output channel oc
. The backtrace lists the program locations
where the most-recently raised exception was raised and where it
was propagated through function calls.let get_backtrace : unit => string
Printexc.get_backtrace ()
returns a string containing the same
exception backtrace that Printexc.print_backtrace
would print.let record_backtrace : bool => unit
Printexc.record_backtrace b
turns recording of exception
backtraces on (if b = true
) or off (if b = false
). Initially,
backtraces are not recorded, unless the b
flag is given to the
program through the OCAMLRUNPARAM
variable.let backtrace_status : unit => bool
Printexc.backtrace_status()
returns true
if exception
backtraces are currently recorded, false
if not.let register_printer : (exn => option string) => unit
Printexc.register_printer fn
registers fn
as an exception
printer. The printer should return None
or raise an exception
if it does not know how to convert the passed exception, and Some
s
with s
the resulting string if it can convert the passed
exception. Exceptions raised by the printer are ignored.
When converting an exception into a string, the printers will be invoked
in the reverse order of their registrations, until a printer returns
a Some s
value (if no such printer exists, the runtime will use a
generic printer).
let print : BatInnerIO.output 'a => exn => unit
print
function is now named !pass
.type raw_backtrace=
Printexc.raw_backtrace
raw_backtrace
stores a backtrace in
a low-level format, instead of directly exposing them as string as
the get_backtrace()
function does.
This allows delaying the formatting of backtraces to when they are actually printed, which may be useful if you record more backtraces than you print.
Raw backtraces cannot be marshalled. If you need marshalling, you
should use the array returned by the backtrace_slots
function of
the next section.
Since 2.2.0 and OCaml 4.01.0
let get_raw_backtrace : unit => raw_backtrace
Printexc.get_raw_backtrace ()
returns the same exception
backtrace that Printexc.print_backtrace
would print, but in
a raw format.let print_raw_backtrace : Pervasives.out_channel => raw_backtrace => unit
Printexc.print_backtrace
uses.let raw_backtrace_to_string : raw_backtrace => string
Printexc.get_backtrace
uses.let get_callstack : int => raw_backtrace
Printexc.get_callstack n
returns a description of the top of the
call stack on the current program point (for the current thread),
with at most n
entries. (Note: this function is not related to
exceptions at all, despite being part of the Printexc
module.)let set_uncaught_exception_handler : (exn => raw_backtrace => unit) => unit
Printexc.set_uncaught_exception_handler fn
registers fn
as the handler
for uncaught exceptions. The default handler prints the exception and
backtrace on standard error output.
Note that when fn
is called all the functions registered with
Pervasives.at_exit
have already been called. Because of this you must
make sure any output channel fn
writes on is flushed.
If fn
raises an exception, it is ignored.
Since 2.3.0 and OCaml 4.02.0
Those function allow to traverse the slots of a raw backtrace,
extract information from them in a programmer-friendly format.
type backtrace_slot=
Printexc.backtrace_slot
backtrace_slot
represents a single slot of
a backtrace.let backtrace_slots : raw_backtrace => option (array backtrace_slot)
None
if none of them
contain useful information.
In the return array, the slot at index 0
corresponds to the most
recent function call, raise, or primitive get_backtrace
call in
the trace.
Some possible reasons for returning None
are as follow:
-g
)ocamlc -g
)type location=
Printexc.location
= {
|
filename : |
|
line_number : |
|
start_char : |
|
end_char : |
start_char
and end_char
are positions relative to the beginning of the
line.module Slot:{
..}
type raw_backtrace_slot=
Printexc.raw_backtrace_slot
Elements of this type can still be compared and hashed: when two
elements are equal, then they represent the same source location
(the converse is not necessarily true in presence of inlining,
for example).
let raw_backtrace_length : raw_backtrace => int
raw_backtrace_length bckt
returns the number of slots in the
backtrace bckt
.let get_raw_backtrace_slot : raw_backtrace => int => raw_backtrace_slot
get_slot bckt pos
returns the slot in position pos
in the
backtrace bckt
.let convert_raw_backtrace_slot : raw_backtrace_slot => backtrace_slot
backtrace_slot
from a low-level
raw_backtrace_slot
.let exn_slot_id : exn => int
Printexc.exn_slot_id
returns an integer which uniquely identifies
the constructor used to create the exception value exn
(in the current runtime).let exn_slot_name : exn => string
Printexc.exn_slot_id exn
returns the internal name of the constructor
used to create the exception value exn
.

09 October 2000
Disease Outbreak Reported
PRESS RELEASE ISSUED BY WHO
9 OCTOBER 2000
WHO APPEALS FOR INTERNATIONAL SUPPORT FOR CONTROL AND PREVENTION OF RIFT VALLEY FEVER (RVF) IN YEMEN
The World Health Organization (WHO) is launching an appeal for US$ 975 000 to support international efforts to control and prevent Rift Valley Fever (RVF) in Yemen. This viral haemorrhagic fever causes severe disease amongst both humans and animals, posing a serious public health risk and economic losses due to loss of livestock.
In September 2000, RVF was reported for the first time outside Africa. Cases were confirmed in Saudi Arabia and Yemen. As of 9 October 2000, 321 cases with 32 deaths, and a case fatality rate of 10%, have been reported by the Ministry of Public Health, Yemen.
The response requires strengthening the basic infrastructure, epidemiological surveillance and human resources in Yemen that are needed for dealing with this emergency. In particular, the economic impact of the restriction on animal movement and trade is causing severe hardship amongst local inhabitants.
High-level agreement between Saudi Arabia and Yemen to conduct a joint investigation has ensured effective coordination of the international response to control the disease on both sides of the border. WHO experts are working with both governments in the outbreak zone.
Funds mobilized through the WHO Appeal will help to control and contain the outbreak of RVF within the immediately affected districts in Yemen, and build local capacity to predict and prevent further occurrence.
The Appeal seeks support for vector surveillance and control, strengthening laboratory capacity, capacity building and human resource development, strengthening epidemiological surveillance of RVF and providing essential supplies, equipment and critical supportive materials.
An urgent response to the Appeal is needed to assist the Government of Yemen and strengthen local capacity to take effective action on the first reported cases of RVF outside traditionally-affected areas in Africa.
RVF is a zoonotic disease. It primarily affects animals (cattle, sheep, camels, goats) but can cause outbreaks of disease in humans. Usually, the virus is spread by the bite of infected mosquitoes. During RVF outbreaks, people become infected with RVF either by being bitten by mosquitoes or through contact with the blood, other body fluids or organs of infected animals. Such contact may occur during the care or slaughtering of infected animals or possibly from the ingestion of raw milk.

Qt Quick Particles Examples - CustomParticle
This is a collection of small QML examples relating to using CustomParticle in the particle system. Each example is a small QML file emphasizing a different way to use CustomParticle.
Blur Particles adds a blur effect to the particles, which increases over the particle's life time. It uses a custom vertex shader:
vertexShader:" uniform lowp float qt_Opacity; varying lowp float fFade; varying lowp float fBlur; void main() { defaultMain(); highp float t = (qt_Timestamp - qt_ParticleData.x) / qt_ParticleData.y; highp float fadeIn = min(t * 10., 1.); highp float fadeOut = 1. - max(0., min((t - 0.75) * 4., 1.)); fFade = fadeIn * fadeOut * qt_Opacity; fBlur = max(0.2 * t, t * qt_ParticleR); } "
to propagate life time simulation to a custom fragment shader:
fragmentShader: " uniform sampler2D source; uniform sampler2D blurred; varying highp vec2 qt_TexCoord0; varying highp float fBlur; varying highp float fFade; void main() { gl_FragColor = mix(texture2D(source, qt_TexCoord0), texture2D(blurred, qt_TexCoord0), min(1.0,fBlur*3.0)) * fFade; }"
which has access to both the normal image sampler and a blurred sampler, the image plus a ShaderEffect.
Fragment Shader just uses the particle system as a vertex delivery system.
fragmentShader: " varying highp vec2 fPos; varying lowp float fFade; varying highp vec2 qt_TexCoord0; void main() {//*2 because this generates dark colors mostly highp vec2 circlePos = qt_TexCoord0*2.0 - vec2(1.0,1.0); highp float dist = length(circlePos); highp float circleFactor = max(min(1.0 - dist, 1.0), 0.0); gl_FragColor = vec4(fPos.x*2.0 - fPos.y, fPos.y*2.0 - fPos.x, fPos.x*fPos.y*2.0, 0.0) * circleFactor * fFade; }"
Image Colors uses CustomParticle to assign colors to particles based on their location in a picture. The vertex shader,
vertexShader:" uniform highp float maxWidth; uniform highp float maxHeight; varying highp vec2 fTex2; varying lowp float fFade; uniform lowp float qt_Opacity; void main() { fTex2 = vec2(qt_ParticlePos.x, qt_ParticlePos.y); //Uncomment this next line for each particle to use full texture, instead of the solid color at the center of the particle. //fTex2 = fTex2 + ((- qt_ParticleData.z / 2. + qt_ParticleData.z) * qt_ParticleTex); //Adjusts size so it's like a chunk of image. fTex2 = fTex2 / vec2(maxWidth, maxHeight); highp float t = (qt_Timestamp - qt_ParticleData.x) / qt_ParticleData.y; fFade = min(t*4., (1.-t*t)*.75) * qt_Opacity; defaultMain(); } "
passes along the starting position for each vertex to the fragment shader,
fragmentShader: " uniform sampler2D particleTexture; uniform sampler2D pictureTexture; varying highp vec2 qt_TexCoord0; varying highp vec2 fTex2; varying lowp float fFade; void main() { gl_FragColor = texture2D(pictureTexture, fTex2) * texture2D(particleTexture, qt_TexCoord0).w * fFade; }"
which uses it to determine the color for that particle.

This is especially useful for accessing the list of Connections of the Session (Session.connections, Session.activeConnections) and use those values to call Session.forceDisconnect, Session.forceUnpublish or Session.updateConnection.
To update all Session objects owned by OpenVidu object at once, call OpenVidu.fetch
A promise resolved to true if the Session status has changed with respect to the server, or to false if not. This applies to any property or sub-property of the Session object
Removes the Connection from the Session. This can translate into a forced eviction of a user from the Session if the
Connection had status active
or into a token invalidation if no user had taken the Connection yet (status pending
).
In the first case, OpenVidu Browser will trigger the proper events in the client-side (streamDestroyed
, connectionDestroyed
,
sessionDisconnected
) with reason set to "forceDisconnectByServer"
.
In the second case, the token of the Connection will be invalidated and no user will be able to connect to the session with it.
This method automatically updates the properties of the local affected objects. This means that there is no need to call Session.fetch or OpenVidu.fetch] to see the changes consequence of the execution of this method applied in the local objects.
The Connection object to remove from the session, or its connectionId
property
A Promise that is resolved if the Connection was successfully removed from the Session and rejected with an Error object if not
Forces some Connection to unpublish a Stream (identified by its streamId
or the corresponding Publisher object owning it).
OpenVidu Browser will trigger the proper events on the client-side (streamDestroyed
) with reason set to "forceUnpublishByServer"
.
You can get publisher
parameter from Connection.publishers array (Publisher.streamId for getting each streamId
property).
Remember to call Session.fetch or OpenVidu.fetch before to fetch the current actual properties of the Session from OpenVidu Server
This method automatically updates the properties of the local affected objects. This means that there is no need to call Session.fetch or OpenVidu.fetch to see the changes consequence of the execution of this method applied in the local objects.
The Publisher object to unpublish, or its streamId
property
A Promise that is resolved if the stream was successfully unpublished and rejected with an Error object if not
A Promise that is resolved to the generated token string if success and rejected with an Error object if not
This feature is part of OpenVidu PRO and ENTERPRISE editions
Updates the properties of a Connection with a ConnectionProperties object. Only these properties can be updated:
This method automatically updates the properties of the local affected objects. This means that there is no need to call Session.fetch or OpenVidu.fetch to see the changes consequence of the execution of this method applied in the local objects.
The affected client will trigger one ConnectionPropertyChangedEvent for each modified property.
The Connection.connectionId of the Connection object to modify
A new ConnectionProperties object with the updated values to apply
A Promise that is resolved to the updated Connection object if the operation was successful and rejected with an Error object if not
Generated using TypeDoc
Array containing the active Connections of the Session. It is a subset of Session.connections array containing only those Connections with property Connection.status to
active
.To get the array of active Connections with their current actual value, you must call Session.fetch or OpenVidu.fetch before consulting property activeConnections

Multiplies the first operand (destination operand) by the second operand (source operand) and stores the result in the destination operand.
In 64-bit mode and not encoded with VEX/EVEX, using a REX prefix in the form of REX.R permits this instruction to access additional registers (XMM8-XMM15).
Legacy SSE version 64-bit operand: The source operand can be an unsigned doubleword integer stored in the low doubleword of an MMX technology register or a 64-bit memory location. The destination operand can be an unsigned doubleword integer stored in the low doubleword an MMX technology register. The result is an unsigned
quadword integer stored in the destination an MMX technology register. When a quadword result is too large to be represented in 64 bits (overflow), the result is wrapped around and the low 64 bits are written to the destination element (that is, the carry is ignored).
For 64-bit memory operands, 64 bits are fetched from memory, but only the low doubleword is used in the compu-tation.
128-bit Legacy SSE version: The second source operand is two packed unsigned doubleword integers stored in the first (low) and third doublewords of an XMM register or a 128-bit memory location. For 128-bit memory operands, 128 bits are fetched from memory, but only the first and third doublewords are used in the computation. The first source operand is two packed unsigned doubleword integers stored in the first and third doublewords of an XMM register. The destination contains two packed unsigned quadword integers stored in an XMM register. Bits (VLMAX-1:128) of the corresponding YMM destination register remain unchanged.
VEX.128 encoded version: The second source operand is two packed unsigned doubleword integers stored in the first (low) and third doublewords of an XMM register or a 128-bit memory location. For 128-bit memory operands, 128 bits are fetched from memory, but only the first and third doublewords are used in the computation. The first source operand is two packed unsigned doubleword integers stored in the first and third doublewords of an XMM register. The destination contains two packed unsigned quadword integers stored in an XMM register. Bits (VLMAX-1:128) of the destination YMM register are zeroed.
VEX.256 encoded version: The second source operand is four packed unsigned doubleword integers stored in the first (low), third, fifth and seventh doublewords of a YMM register or a 256-bit memory location. For 256-bit memory operands, 256 bits are fetched from memory, but only the first, third, fifth and seventh doublewords are used in the computation. The first source operand is four packed unsigned doubleword integers stored in the first, third, fifth and seventh doublewords of an YMM register. The destination contains four packed unaligned quadword integers stored in an YMM register.
EVEX encoded version: The input unsigned doubleword integers are taken from the even-numbered elements of the source operands. The first source operand is a ZMM/YMM/XMM registers. The second source operand can be an ZMM/YMM/XMM register, a 512/256/128-bit memory location or a 512/256/128-bit vector broadcasted from a 64-bit memory location. The destination is a ZMM/YMM/XMM register, and updated according to the writemask at 64-bit granularity.

S3 Provider¶
The S3 provider uses S3 to store commits remotely in a S3 bucket. Each commit is stored as an tar archive, with the commit metadata attached as object metadata. The URI format is:
s3://<bucket>/<key>
Commits will be created at <key>/<commitid>/<archive>.tar.gz
. The commit
metadata will be stored at the <commitid>
level. In addition, the commits
are stored in file named titan
at the root of the repository. This makes it
more efficient to list commits, and allows the S3 Web Provider to
pull data.
The AWS credentials are pulled using the default AWS credential chain at
the time you do the push or pull operation. So you must have the
AWS_*
environment variables set, or use your ~/.aws
configuration.
Because the S3 provider uses the standard AWS SDK, all variations of credentials
should be supported, including specifying a profile with AWS_PROFILE
or
using MFA (multi factor authentication) session tokens. To pull a commit, you
will need s3:GetObject
permissions. To push a commit, you will need
s3:PutObject
permissions.
Although not recommended, it is possible to pass accessKey
, secretKey
,
and region
to the S3 Provider during runtime through CLI parameters:
s3://<bucket>/<key> -p accessKey=value -p secretKey=value -p region=value
The S3 provider relies on basic AWS APIs to implement its functionality, and as such has limited scalability. For example, all commits are stored in a single metadata file, and there are no provisions for keeping that metadata consistent in the face of simultaneous pushes. It should only be used for storing relatively small numbers of commits. Improving this will require a new provider that includes a robust metadata layer on top of the base S3 functionality.
SSH Specific Parameters¶
accessKey=aws_access_key_id AWS Access Key ID
secretKey=aws_secret_access_key AWS Secret Access Key
region=region AWS Region

Gary Lineker responds to Liverpool FC’s 2-1 win at Crystal Palace
Gary Lineker takes to social media after Liverpool FC's late and dramatic 2-1 win at Crystal Palace
by Social SpyGary Lineker has taken to social media to praise Liverpool FC’s resilience after they claimed a 2-1 win at Crystal Palace to continue their fine start to the new season.
The Reds headed into the game looking to make it 12 wins from 13 in the top flight and on the back of their 3-1 victory over Manchester City before the international break.
Sadio Mane gave the visitors the lead in the 49th minute at Selhurst Park with his 10th goal of the season.
However, the home side looked to have earned a point when Wilfried Zaha netted in the 82nd minute to equalise for the Eagles.
But it was Liverpool FC who had the final say, with Roberto Firmino scoring the all-important winner in the 85th minute as they claimed all three points to maintain their place at the top of the Premier League table.
England legend Lineker was clearly impressed by Liverpool FC’s fighting spirit as they claimed all three points to underline their status as title favourites.
Lineker wrote on Twitter after Firmino’s equaliser: “Scruffiest of goals from Firmino makes it 2-1. This @LFC side certainly find a way to win.”
Liverpool FC are aiming to win the Premier League title this season after having finished second behind Manchester City last term.
They will take on Napoli at home in the Champions League on Wednesday night, before preparing for their next Premier League game – a home clash against Brighton and Hove Albion next weekend.
The Reds are yet to lose a game in the Premier League and have only dropped two points so far this season.


Mix-in Class for GAP-based Groups#
This class adds access to GAP functionality to groups such that parent
and element have a gap()
method that returns a GAP object for
the parent/element.
If your group implementation uses libgap, then you should add
GroupMixinLibGAP
as the first class that you are deriving
from. This ensures that it properly overrides any default methods that
just raise NotImplementedError
.
- class sage.groups.libgap_mixin.GroupMixinLibGAP#

Hire purchase system
LINK IS HERE
This is a system which I did as my Final year project in strathmore.
This system deals with selling products on the market on a hire purchase.
It was designed for the company KCT (Kenya Creddit traders)
where I did my internship.
It was designed with PHP, HTML AND CSS.
Stock management system
LINK IS HERE
This system was designed to manage and keep track of products within
a children's home (Thomas Barnados)
since one of the problems
they had was keeping track of their products.
It was designed with PHP, HTML AND CSS.

They did not have a system which enabled patients to
know how long they will wait in queues.
It was also designed for keeping track of patient appointments.
It was designed with PHP, HTML AND CSS.
I completed my Degree at Strathmore University having pursued
a bachelor’s Degree in Business in Information Technology (BBIT)
and graduated in June 2019.
I've worked at Unclaimed Financial
Assets Authority for 3 months. My active involvement in this certain
career field has done so well in developing my communication,
analytical, organizational and leadership skills, which are vital
in finding success in the corporate world.
I therefore wish to expand my knowledge, skills and commitment at
Moringa school. I believe I can learn alot at Moringa School since
I have a passion in programing. It is my interest to put into practice
the knowledge that I will aquire in a work site in future.
I like travelling and exploring new places.
I enjoy outdoor sport activities such as swimming and football.
I play chess as a leisure activity.
To be a leading software developer with an aim of building a unique software that will bring a big inpact to the future technology.

Gareth Turner aka LOOSH'72 has been passionate about electronic music since the late 80's when the acid house scene & warehouse parties exploded in the UK, he started Dj'ing in 1991, originally playing Italian piano & house music, eventually his main focus turned to progressive house, trance & techno, after Dj'ing at various clubs & pubs in the North West of England in the late 90's & early 2000's he quit in 2004, after a long spell away from the scene he's picked up the baton again & is back with a renewed passion playing various genres including progressive house, trance, techno, old skool & drum & bass.


Growing up this was a game that me and all of my buddies played when ever we had the chance. It's really unique mix up of both golf and baseball!  Imagine all around the field you have holes or targets that you have to hit in order to complete that shot for the round. Some example I can give you would be a water cooler in the dugout or a sign on the outfield fence. The players have to tee off in this game by throwing the ball up to themselves and hitting. From this point where ever the ball lands the player has to putt just you would in golf to make the shot. There are some other variation on how to putt but for now thats the way we have it in the game. Currently this version of the game is available in the google play store Click here to download
The first game was cool and all but not even close to where I see it going. We have completely revamped all of the graphics in the game. We have updated all of the characters to 3D models, added a new main menu screen, new locker room, all new gear and power ups for a customization feature, and also added some new fields. The game is set to release in a couple of months on both IOS and android devices! Here are a few screen shots, dont wanna show to much, I'd rather it be a suprise!
