Rust is a really interesting new programming language.
Rust is a good choice when you'd choose C++. And maybe other times.
Rust was written by Graydon Hoare. Mozilla has taken stewardship.
Mozilla writes lots of C++, and feels that pain.
Rust is written in Rust.
Mozilla is developing Servo in Rust as well.
Servo is a web rendering engine. Think Gecko or WebKit.
There are no plans to replace Gecko. It is focused on mobile.
Massively paralell.
Rust is currently at version 0.8.
Snapshots, not backwards compatible.
1.0 is coming soon.

In the era of upcoming technology, we need a strong technology in order to enhance our reading, learning skill by developing a complete module which will resolve the current reading, learning and acquiring knowledge related problems. We are going to interconnect the various libraries located at different places (mainly libraries in city central, college, personal, etc.). As our team believe that “More you read, the more you know”. Because, Reading develops the mind. In short quote form Margaret Fuller “Today a reader, Tomorrow a Leader”. So, there is no barrier such as lack of time, money and interest in order to enhance reading skills.

Forbes contributor Peter Greene has reviewed Teaching Machines. I'm particularly fond of the kicker:
The book is fascinating and very readable, loaded with well-chosen details. Reading this story, one suspects it might be fair to say that it is ed tech, not public education, that has not made a significant step forward in the last 100 years.

Chapter 14 Advanced Disk I/O Concepts
This chapter describes the internal operations of a disk drive. The description is followed by the calculations you need to determine the number of I/Os per second your system can support. These numbers are very important in putting together the system configuration.
In many large systems, the number of I/Os per second that the system can support may be determined by a bottleneck in a single drive. If the RDBMS is waiting for a specific piece of information before it can proceed with the transaction, any time spent waiting (called latency) can affect the performance of the entire transaction.
A disk drive has certain limitations you cannot exceed. Once you reach this limit, you cannot achieve a higher I/O rate and performance suffers. As you see in this chapter, you can overcome this problem by adding more or faster disk drives. By understanding these limitations, you will have the knowledge necessary to optimize the use of these disks to achieve the best performance possible.
Disk Operation
A disk drive is an electronic storage device that holds information. The disk holds that information on the disk magnetically. To read the disk, the input device (head) moves over the place where the information is held and determines how the information has been stored. Depending on the magnetism of the spot on the disk, the value of the data is either 0 or 1.
Consider the individual components first and then look at the entire disk drive as it works together to store and retrieve information. The disk drive is made up of thin disks of magnetic storage material called platters. These platters look very much like the compact discs (CDs) with which you are familiar.
The platter is divided into tracks. A track is the path on which the disk stores information (see Figure 14.1). Tracks are further separated into sectors; it is in these sectors that the data is actually stored. There may be 512 or 1,024 bytes per sector, depending on the drive manufacturer.
Figure 14.1 A disk platter.
You may have one or more platters in your disk drive. Evolving disk drive technology has allowed manufacturers to pack the tracks tighter, allowing more information to be stored on a platter. The total disk space you have is the product of the number of bytes per platter times the number of platters.
The disk platters rotate at anywhere from 4,000 to 8,000 RPM (revolutions per minute). As the platter rotates, the heads move in and out on a linear path (see Figure 14.2). The heads are attached to a disk arm that is used to move the heads in and out.
Figure 14.2 The disk arm and heads.
Usually, the heads and arms are connected so that when the arm moves, all the heads move simultaneously. The heads are moved by a small, very precise motor. As information is requested, the disk arm moves the head over the d
1000
esired track; the disk then simply waits for the desired data to move underneath the head. In this manner, all data is retrieved from the disk.
A cylinder is a stack of vertically aligned tracks. Because all the heads are connected, they are all over the same track on different platters. The set of tracks on top of which the heads are located is really what is called the cylinder (see Figure 14.3).
Figure 14.3 Disk cylinders.
A motor is dedicated to spinning the platters. This motor must be very precise. The final component in the disk drive is the electronics used to control the motors and move the head to the correct place on the disk.
Usually, the disk drive also has a small buffer used to move data in and out of the disk more efficiently. This buffer can be used to sort multiple data requests to try to reduce seek time.
Seek Time
A seek refers to moving the head to the proper track. The seek time is the time it takes for the heads to move over to that proper track (see Figure 14.4). If you look at the specifications for your disk drive, you will most likely find specifications for single-track, average, and full-stroke seek times. These statistics give you an idea of approximately how long it takes to get to your data. Single-track seek time means the time it takes to move to the next adjacent track. Average seek time means the average time you can expect the seek to take. Full-stroke seek time means the time it takes to seek from the first track to the last track.
Figure 14.4 A disk seek.
For a typical disk drive available today, the average seek time is from 8 to 15 milliseconds. The single-track seek time is from 3 to 5 milliseconds and the full-stroke seek time is around 15 to 25 milliseconds.
The seek time is very important; it is the seek time and the rotational latency time that really add up to all the time you spend getting to the data. Once you have actually found the data, it takes very little time to transfer that data to memory.
Rotational Latency
Once you move the heads to position them on the proper track, you may have to wait for the platter to rotate until the actual sectors in which you are interested are under the head. The time you spend waiting for the platter to rotate is called the rotational latency.
Suppose that your disk drive has a rotational speed of 4,500 RPM. Its number of revolutions per second can be calculated as follows:
Revolutions per second = 4500 revolutions per minute / 60 seconds per
minute = 75 revolutions per second
Once you know the number of revolutions per second, you can do a simple inversion and determine the number of seconds per revolution:
Seconds per revolution = 1/75 revolutions per second = 0.0133 seconds per
revolution = 13.33 milliseconds per revolution
Now you know how long it takes for a complete revolution to take place. (Some high-speed SCSI disks have a rotational speed of 7,200 RPM, which results in a rate of 8.33 msec per revolution!) You can guess that the average rotational latency is approximately half a revolution:
Average Rotational Latency = 13.33 msec per revolution / 2 = 6.66 msec
For the example of the disk dri
e1f
ve with a rotational speed of 4,500 RPM, the average rotational latency is 6.66 milliseconds. This data is just another piece in the equation used to determine how many I/Os per second your disk drive can handle.

PHILOSOPHY
First, Salvia Divinorum is a most wonderful herb -- it is a friend to humans: the fresh leaves aid in digestion, at just above threshold doses it can stimulate lucid dreaming, and at higher doses it can give its acolytes the ability to experience plant consciousness ( -- or could it be that we are merely vessels by which Salvia experiences animal consciousness?)
It is a very religious herb. It imposes its own order on the human mind, and that is very un-nerving. It can instantly reduce the very fabric of human perception into a swirly multi-dimensional floormat upon which it wipes its multi-tendriled feet before entering the 'room' to say hello. This is uncomfortable at best, and pure-terrifying at worst.
It is human catnip. In fact, some humans (and 1/3 of all cats) have no reaction whatsoever to their respective herb. I've gotten into pleasurable/annoyed hissy fits at simply the smell of the dried herb, just like my cats. My cats are mildly interested in Salvia Divinorum, and I keep my stash locked up.
It is nootropic -- ask the goddess a question, and she will re-tool my mind-mechanics to best help me obtain an answer.  Salvia Divinorum cuts to the chase, and this too, can be frightening for those not ready to get on with the ill-defined act of living in the present.
Salvia does not seem to like being a diversion, a salve for the boredom/dissatisfaction affliction that plagues western society like a new fangled gout.
EXPERIENCES
My smoking experiences (6x enhanced leaf): The come-up feels like passing out, my extremities are numb and tingling. Salvia has its own tempo, its own rhythm. The distorted visuals pulse and dance in a joyful way. There is an intense gravity that doesn't always pull straight down, and varies from locale to locale. It feels so god awful familiar. I am reminded of childhoods I am not sure I lived. I feel bristly, like I'm being scrubbed all over by a boar's hair brush. I get angry and disappointed for some yet unknown reason -- its as if, my entire perception is torn to shreds and I'm thinking to myself 'is this all there is to the experience?'
My sublingual experiences: I bought a tiny plant which for the life of me I can't get to grow. It sheds its tiny leaves which I collect and chew on. I feel cool glowing spots on the inside of my mouth where the leaves are touching my gum. I can get a fairly subtle and buzzy reaction combining tiny leaves with my friend ganja to the point of beautiful geometric CEVs in blue and green and gold. I also become aware of energy pathways throughout my abode that twist like tree roots.
My quid experiences: a bag of dried leaves. I first try making a water extract, repeatedly boiling the leaf juice down to a tablespoonful. This doesn't work.  Yuck! It's like eating leaves out of a hefty bag in the autumn. You can really taste the medicine in the leaves! Eventually I've got a big quid going, and I eat more and more, and in the darkness, subtle patterns enfold my being, and for a couple of hours I become an old lichen covered rock in a field of oak trees -- oh how lovely to be an old rock!!
My tinture experiences: got a bag of dried leaves, and a bottle of tincture. The tincture is impossible to work with -- pure grain alcohol stings white-hot, and watering it down seems to dull the effect. So with 1/2 oz of tincture, and a couple of dry leaves, I created my own enhanced leaf which was so strong that it could be rolled into a joint (with ganja of course!) and still get me to a V or an I state.
CONCLUSION
I am of the opinion that the very BEST way to commune with the Yerba is to grow your own and quid the fresh leaves. The smoking experience, although it is very intense, does not provide the necessary context for integration. I've had some very lucid and powerful experiences with most of the methods, but my peak moments were with quid.

It is often required that, large datasets needs to be rendered in the front-end table. Cuppa Angular 2 Data Grid components handles 10K + records with high performance. Developed using Angular 2
, TypeScript
, HTML
, CSS
10k + records
with high performanceSorting algorithm
filtering
and search algorithm
npm install cuppa-ng2-grid
CuppaDataGridModule
from the installed package into your module as follows:import { CuppaDataGridModule } from 'cuppa-ng2-grid/cuppa-ng2-dataGrid';
ngModule
as follows:@NgModule({
bootstrap: [ AppComponent ],
declarations: [
AppComponent,
NoContentComponent ],
imports: [
BrowserModule,
FormsModule,
HttpModule,
CuppaDataGridModule // Import DataGrid module variable here
]
})
<cuppa-datagrid [datalist] = “arrayList” [config]=”config” (onRowSelect)=”onRowClick($event)”></cuppa-datagrid>
### JS
- Component requires a `config` object to configure the grid and `datalist` to pass data to the component, as follows:
```js
export class AppComponent implements OnInit {
private config = {
title: "Cuppa Data Table",
w: 300,
h: 300,
itemHeight: 31,
totalRows: 10000,
items: this.arrayList,
sort:{'id':'desc'}
}
private arrayList:any[] =
[
{"id":1,"name":"Mayo","mobile":9240592804},
{"id":2,"name":"Nelson","mobile":9008774782},
{"id":3,"name":"Nichols","mobile":9965852134},
{"id":4,"name":"Summers","mobile":9600712058},

{"id":10,"name":"Gonzalez","mobile":9946879817},
{"id":11,"name":"Dorsey","mobile":9243595415}
];
private onRowClick(row:any){
console.log(row);
alert("selected row:"+ row.id +" "+row.name+" "+row.mobile);
}
}
The following config options can be used
| Setting | Type | Description |
|---|---|---|
| title | String | Set the title of the table |
| w | Number | Set the width of the table. |
| h | Number | Set the height of the table. |
| itemHeight | Number | Set the height of the row. |
| totalRows | Number | Total number of records. |
| items | Array | Array of table records. |
| sort | Object | Object to set the default column for sorting. |
Custom content or elements can be added to table columns.
<c-column>
- Column component for the table. <cuppa-datagrid [datalist] = "arrayList" [config]="config">
<c-column field="id"></c-column>
<c-column field="name">
<ng-template let-person="rowData">

</ng-template>
</c-column>
<c-column field="mobile"></c-column>

使用Glance镜像公共API¶
Glance完全实现了OpenStack镜像API的1.0、1.1和2.0版本。镜像API定义（Specification）是随着Glance开发的，但这并不是Glance项目的一部分。
认证¶
Glance依赖Keystone和OpenStack认证API来处理客户端的认证。你必须从Keystone获得认证令牌（Token）并通过 X-Auth-Token
头来发送所有Glance API请求。Glance会与Keystone通信来认证令牌并获得你的认证签名（Credential）。
阅读 Keystone认证 获得更多与Keystone集成的信息。
使用v1.X¶
为了举例，假设有个Glance API服务器运行在地址 http://glance.example.com
并且默认端口是80.
列举可用的镜像¶
我们想要列举一个授权用户能够访问的可用镜像列表。这包括了用户拥有的镜像、其他用户分享的镜像和公共的镜像。
我们发送 GET
请求到 http://glance.example.com/v1/images
来请求这些可用镜像的列表。返回的数据是以下格式的JSON编码映射:
{'images': [
{'uri': 'http://glance.example.com/v1/images/71c675ab-d94f-49cd-a114-e12490b328d9',
'name': 'Ubuntu 10.04 Plain',
'disk_format': 'vhd',
'container_format': 'ovf',
'size': '5368709120'}
...]}
详细得列举可用的镜像¶
我们想要列举一个授权用户能够访问更详细的可用镜像列表。这包括了用户拥有的镜像、其他用户分享的镜像和公共的镜像。
我们发送 GET
请求到 http://glance.example.com/v1/images/detail
来请求这些可用镜像的列表。返回的数据是以下格式的JSON编码映射:
{'images': [
{'uri': 'http://glance.example.com/v1/images/71c675ab-d94f-49cd-a114-e12490b328d9',
'name': 'Ubuntu 10.04 Plain 5GB',
'disk_format': 'vhd',
'container_format': 'ovf',
'size': '5368709120',
'checksum': 'c2e5db72bd7fd153f53ede5da5a06de3',
'created_at': '2010-02-03 09:34:01',
'updated_at': '2010-02-03 09:34:01',
'deleted_at': '',
'status': 'active',
'is_public': true,
'min_ram': 256,
'min_disk': 5,
'owner': null,
'properties': {'distro': 'Ubuntu 10.04 LTS'}},
...]}
过滤镜像列表¶
GET /v1/images
和GET /v1/images/detail
请求都可用接受查询参数来过滤返回的镜像列表。下面的列表详细介绍这些请求参数。
name=NAME
过滤拥有能够匹配
NAME

These two resources also accept additional query parameters:
sort_key=KEY
Results will be ordered by the specified image attribute
KEY
. Accepted values includeid
,name
,status
,disk_format
,container_format
,size
,created_at
(default) andupdated_at
.sort_dir=DIR
Results will be sorted in the direction
DIR
. Accepted values areasc
for ascending ordesc
(default) for descending.marker=ID
An image identifier marker may be specified. When present only images which occur after the identifier
ID
will be listed, i.e. the images which have a sort_key later than that of the markerID
in the sort_dir direction.limit=LIMIT
When present the maximum number of results returned will not exceed
LIMIT
.
is_public=PUBLIC
An admin user may use the is_public parameter to control which results are returned.
When the is_public parameter is absent or set to True the following images will be listed: Images whose is_public field is True, owned images and shared images.
When the is_public parameter is set to False the following images will be listed: Images (owned, shared, or non-owned) whose is_public field is False.
When the is_public parameter is set to None all images will be listed irrespective of owner, shared status or the is_public field.
获得镜像元数据¶
我们想看看Glance服务器知道的指定虚拟机镜像的详细信息。
我们已经请求过Glance服务器的镜像列表，返回的数据包括每个可用镜像的 uri 字段。这个 uri 字段值包含需要获得制定镜像元数据的实际地址。
继续上面的例子，为了获得第一个返回镜像的元数据，我们用镜像URI可以发送 HEAD
请求到Gance服务器。
我们发送 HEAD
请求到 http://glance.example.com/v1/images/71c675ab-d94f-49cd-a114-e12490b328d9
来获得该镜像的完整元数据。元数据是按照HTTP头集合的形式返回，这些都以 x-image-meta-
为前缀。下面展示从上面 HEAD
请求返回的HTTP头例子:
x-image-meta-uri http://glance.example.com/v1/images/71c675ab-d94f-49cd-a114-e12490b328d9

添加新的镜像¶
We have created a new virtual machine image in some way (created a “golden image” or snapshotted/backed up an existing image) and we wish to do two things:
- Store the disk image data in Glance
- Store metadata about this image in Glance
We can do the above two activities in a single call to the Glance API.
Assuming, like in the examples above, that a Glance API server is running
at glance.example.com
, we issue a POST
request to add an image to
Glance:
POST http://glance.example.com/v1/images
The metadata about the image is sent to Glance in HTTP headers. The body of the HTTP request to the Glance API will be the MIME-encoded disk image data.
保留新的镜像¶
We can also perform the activities described in `Add a New Image`_ using two separate calls to the Image API; the first to register the image metadata, and the second to add the image disk data. This is known as “reserving” an image.
The first call should be a POST
to http://glance.example.com/v1/images
,
which will result in a new image id being registered with a status of
queued
:
{"image":
{"status": "queued",
"id": "71c675ab-d94f-49cd-a114-e12490b328d9",
...}
...}
The image data can then be added using a PUT
to
http://glance.example.com/v1/images/71c675ab-d94f-49cd-a114-e12490b328d9
.
The image status will then be set to active
by Glance.
镜像元数据的HTTP头
Glance will view as image metadata any HTTP header that it receives in a
POST
request where the header key is prefixed with the strings
x-image-meta-
and x-image-meta-property-
.
The list of metadata headers that Glance accepts are listed below.
x-image-meta-name
This header is required, unless reserving an image. Its value should be the name of the image.
Note that the name of an image is not unique to a Glance node. It would be an unrealistic expectation of users to know all the unique names of all other user’s images.
x-image-meta-id
This header is optional.
When present, Glance will use the supplied identifier for the image. If the identifier already exists in that Glance node, then a 409 Conflict will be returned by Glance. The value of the header must be an uuid in hexadecimal string notation (i.e. 71c675ab-d94f-49cd-a114-e12490b328d9).
When this header is not present, Glance will generate an identifier for the image and return this identifier in the response (see below)
x-image-meta-store
This header is optional. Valid values are one of
file
,s3
,rbd
,swift
,cinder
,gridfs
,sheepdog
orvsphere
When present, Glance will attempt to store the disk image data in the backing store indicated by the value of the header. If the Glance node does not support the backing store, Glance will return a 400 Bad Request.
When not present, Glance will store the disk image data in the backing store that is marked default. See the configuration option
default_store
for more information.x-image-meta-disk_format
This header is required, unless reserving an image. Valid values are one of
aki
,ari
,ami
,raw
,iso
,vhd
,vdi
,qcow2
, orvmdk
.For more information, see About Disk and Container Formats
x-image-meta-container_format
This header is required, unless reserving an image. Valid values are one of
aki
,ari
,ami
,bare
, orovf
.For more information, see About Disk and Container Formats
x-image-meta-size
This header is optional.
When present, Glance assumes that the expected size of the request body will be the value of this header. If the length in bytes of the request body does not match the value of this header, Glance will return a 400 Bad Request.
When not present, Glance will calculate the image’s size based on the size of the request body.
x-image-meta-checksum
This header is optional. When present it shall be the expected MD5 checksum of the image file data.
When present, Glance will verify the checksum generated from the backend store when storing your image against this value and return a 400 Bad Request if the values do not match.
x-image-meta-is_public
This header is optional.
When Glance finds the string “true” (case-insensitive), the image is marked as a public image, meaning that any user may view its metadata and may read the disk image from Glance.
When not present, the image is assumed to be not public and owned by a user.
x-image-meta-min_ram
This header is optional. When present it shall be the expected minimum ram required in megabytes to run this image on a server.
When not present, the image is assumed to have a minimum ram requirement of 0.
x-image-meta-min_disk
This header is optional. When present it shall be the expected minimum disk space required in gigabytes to run this image on a server.
When not present, the image is assumed to have a minimum disk space requirement of 0.
x-image-meta-owner
This header is optional and only meaningful for admins.
Glance normally sets the owner of an image to be the tenant or user (depending on the “owner_is_tenant” configuration option) of the authenticated user issuing the request. However, if the authenticated user has the Admin role, this default may be overridden by setting this header to null or to a string identifying the owner of the image.
x-image-meta-property-*
When Glance receives any HTTP header whose key begins with the string prefix
x-image-meta-property-
, Glance adds the key and value to a set of custom, free-form image properties stored with the image. The key is the lower-cased string following the prefixx-image-meta-property-
with dashes and punctuation replaced with underscores.For example, if the following HTTP header were sent:
x-image-meta-property-distro Ubuntu 10.10
Then a key/value pair of “distro”/”Ubuntu 10.10” will be stored with the image in Glance.
There is no limit on the number of free-form key/value attributes that can be attached to the image. However, keep in mind that the 8K limit on the size of all HTTP headers sent in a request will effectively limit the number of image properties.
更新镜像¶
Glance will view as image metadata any HTTP header that it receives in a
PUT
request where the header key is prefixed with the strings
x-image-meta-
and x-image-meta-property-
.
If an image was previously reserved, and thus is in the queued
state, then
image data can be added by including it as the request body. If the image
already as data associated with it (e.g. not in the queued
state), then
including a request body will result in a 409 Conflict exception.
On success, the PUT
request will return the image metadata encoded as HTTP
headers.
See more about image statuses here: Image Statuses
列举镜像成员关系（Membership）¶
We want to see a list of the other system tenants (or users, if
“owner_is_tenant” is False) that may access a given virtual machine image that
the Glance server knows about. We take the uri field of the image data,
append /members
to it, and issue a GET
request on the resulting URL.
Continuing from the example above, in order to get the memberships for the
first image returned, we can issue a GET
request to the Glance
server for
http://glance.example.com/v1/images/71c675ab-d94f-49cd-a114-e12490b328d9/members
. What we will get back is JSON data such as the following:
{'members': [
{'member_id': 'tenant1',
'can_share': false}
...]}
The member_id field identifies a tenant with which the image is shared. If that tenant is authorized to further share the image, the can_share field is true.
列举共享的镜像¶
We want to see a list of images which are shared with a given tenant. We issue
a GET
request to http://glance.example.com/v1/shared-images/tenant1
. We
will get back JSON data such as the following:
{'shared_images': [
{'image_id': '71c675ab-d94f-49cd-a114-e12490b328d9',
'can_share': false}
...]}
The image_id field identifies an image shared with the tenant named by member_id. If the tenant is authorized to further share the image, the can_share field is true.
添加镜像成员¶
We want to authorize a tenant to access a private image. We issue a PUT
request to
http://glance.example.com/v1/images/71c675ab-d94f-49cd-a114-e12490b328d9/members/tenant1
. With no body, this will add the membership to the image, leaving existing
memberships unmodified and defaulting new memberships to have can_share
set to false. We may also optionally attach a body of the following form:
{'member':
{'can_share': true}
}
If such a body is provided, both existing and new memberships will have can_share set to the provided value (either true or false). This query will return a 204 (“No Content”) status code.
从镜像中移除成员¶
We want to revoke a tenant’s right to access a private image. We issue a
DELETE
request to http://glance.example.com/v1/images/1/members/tenant1
.
This query will return a 204 (“No Content”) status code.
代替镜像的成员关系列表¶
The full membership list for a given image may be replaced. We issue a PUT
request to
http://glance.example.com/v1/images/71c675ab-d94f-49cd-a114-e12490b328d9/members
with a body of the following form:
{'memberships': [
{'member_id': 'tenant1',
'can_share': false}
...]}
All existing memberships which are not named in the replacement body are removed, and those which are named have their can_share settings changed as specified. (The can_share setting may be omitted, which will cause that setting to remain unchanged in the existing memberships.) All new memberships will be created, with can_share defaulting to false if it is not specified.
在2.0版本镜像成员的修改¶
Version 2.0 of the Images API eliminates the can_share
attribute of image
membership. In the version 2.0 model, image sharing is not transitive.
In version 2.0, image members have a status
attribute that reflects how the
image should be treated with respect to that image member’s image list.
- The
status
attribute may have one of three values:pending
,accepted
, orrejected
. - By default, only those shared images with status
accepted
are included in an image member’s image-list. - Only an image member may change his/her own membership status.
- Only an image owner may create members on an image. The status of a newly
created image member is
pending
. The image owner cannot change the status of a member.
1.x API调用的区别¶
The response to a request to list the members of an image has changed.
call:
GET
on/v2/images/{imageId}/members
response: see the JSON schema at
/v2/schemas/members
The request body in the call to create an image member has changed.
call:
POST
to/v2/images/{imageId}/members
request body:
{ "member": "<MEMBER_ID>" }
where the {memberId} is the tenant ID of the image member.
The member status of a newly created image member is
pending
.
新API调用¶
Change the status of an image member
call:
PUT
on/v2/images/{imageId}/members/{memberId}
request body:
{ "status": "<STATUS_VALUE>" }
where <STATUS_VALUE> is one of
pending
,accepted
, orrejected
. The {memberId} is the tenant ID of the image member.
API消息本地化¶
Glance支持HTTP消息的本地化。举个例子，一个HTTP客户端即使服务器本地（Locale）语言是英文也可以接收到中文的API信息。
如何使用它¶
要获得本地化的API消息，HTTP客户端需要指定 Accept-Language 头来申明用什么语言翻译消息。关于Accept-Language更多的内容请参考 http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html
一个典型的API请求是类似下面这样子的:
curl -i -X GET -H 'Accept-Language: zh' -H 'Content-Type: application/json'
http://<IP_ADDRESS>:9292/v2/images/aaa
然后响应信息是类似下面这样子的:
HTTP/1.1 404 Not Found
Content-Length: 234
Content-Type: text/html; charset=UTF-8
X-Openstack-Request-Id: req-54d403a0-064e-4544-8faf-4aeef086f45a

However, this cache or job was eventually cleared (as this error did not persist).

thank you @kayiwa
We discussed possibly removing the update_cache: true
line from most if not all apt tasks and moving that operation into a separate playbook or tasks file that does not run every time the common
role runs.
When update_cache
is set to true
, Ansible tries to update the local index/list of packages and versions available from apt - the Ansible equivalent of typing sudo apt-get update
. This is useful in general - it's a good idea to keep the apt index up-to-date. However, most of our apt tasks don't upgrade packages, so we don't absolutely need to update the cache before running most of them. And updating the cache does fail fairly often due to changing keys and other issues, which blocks other work from getting done.
Updating the cache is non-destructive and can be done on all infrastructure on a regular basis. So if we have a separate playbook for updating the apt cache, we can run it monthly or quarterly and fix any issues that come up.

XTech 2006 is is coming up, and I’ll be speaking about the state of web graphics, specifically about incorporating graphics in web applications. There will be some SVG, and some Canvas; some 2D and some 3D. Hopefully there will be a handful of cool tech demos, as well as some examples of real-world apps that are using these technologies.
I’ll post the presentation here after it’s been given — the main message I want to get across is that web apps can progress beyond form input and text/numeric data display without having to resort to Flash or other non-web methods. We’ll see how that goes…
Other than myself, there are going to be a whole bunch of Mozilla folks in attendance and presenting, so it should be a good conference.


Ably Mapbox NavSDK demo
The publishing driver SDK runs on Android and publishes the enhanced lat/long locations to an Ably channel, and these locations are shown on a map clipped to a road. View a demo using your preferred map provider with one of the links below.
If you have accessed this site without API keys specified in the URL query parameters, when you click either of the below links you will be prompted to enter an API key for the map provider you have chosen. Please see the official documentation for how to create an API key (Google Maps, Mapbox).

this
customize(
array $optionArray)
Sets any configuration option, with no checks for type / validity
This is more or less a bandaid to remove the handcuffs from users who want to add options that Google has added, that I have not. I didn't intend to restrict the user to only select options, as the goal was to type check and validate. This method can be used to set any option, just pass in arrays with key value pairs for any setting.
If the setting is an object, per the google docs, then use multi-dimensional arrays and they will be converted upon rendering.
This method will most likely be brought into 3.0 to prevent BC breaks, but I will incorporate the same functionality without the need for the extra customize() method call.

Last week I watched a pretty cool GOTO Conference talk [1] with Mikael Vidstedt, director of Software Engineering at Oracle, where he presents many of the upcoming and currently being worked on Java features. One of those, Project Panama, stood out as particularly interesting to me.
#Java has changed more in the last year than in the previous five years.
— GOTO (@GOTOcon) June 5, 2019
Learn about these changes and what Java's future holds in this #GOTOchgo talk with @gsaab and @MikaelVidstedthttps://t.co/QcX8MnEQZL
Disclaimer: Project Panama is still in its early stages of development, so the contents of this article may not reflect its current state.
Project Panama, available in early-access JDK 13 builds, is meant as a bridge between Java and native code. How is this useful? There are certain use cases where a piece of functionality is available as a library written in C or C++ and the requirement is to integrate it into a Java application. The current solution is to use the Java Native Interface (JNI) [2] which could require a vast amount of work and is also quite error-prone. You need to have a good grasp of the native library’s insides and then write all the required implementations to bridge the Java interface with the native code. From my experience, calling native library functions that may change at some later point in time and also managing heap memory allocations could be a real challenge with JNI. To quote Mikael as he says it on the video:
How many people here have written JNI or, you know, done JNI? We’re so sorry for you!
This is where Panama comes into play. It provides new tools and API to simplify the bridging between Java and native code. It basically boils down to the following steps:
This allows you to concentrate on writing the core logic of your application, rather than fiddling with glue code and integration details.
Project Panama’s documentation pages [3] already provide a solid number of examples to start with. I’ll just take a quick peek at how to bridge and run a libCurl Java app and then I’d like to present a more detailed example - a simple SSH client that I wrote based on libSSH2.
I’m running these examples on a macOS, but with a few tweaks you should also be able to run them on a Linux installation.
How to download a web page using the native Curl library’s implementation? Well, first we need to get and extract a Panama OpenJDK build archive.
Let’s open up a shell and set the JAVA_HOME
environment variable to where the OpenJDK build archive is extracted.
export JAVA_HOME=/opt/jdk-13.jdk
Now we need to generate the Java interfaces, the glue code that will bind Java code to the native library. This will produce a curl.jar
file:
$JAVA_HOME/bin/jextract -t org.unix -L /usr/lib -lcurl \
--record-library-path /usr/include/curl/curl.h \
-o curl.jar
When we inspect the JAR file, we can see all the Curl API calls, as well as dependency bindings. The Curl API is available through the new java.foreign Java API.
Now for a quick example. Here’s a Java piece of code that fetches a web page and displays its contents on screen.
import java.lang.invoke.*;
import java.foreign.*;
import java.foreign.memory.*;
import org.unix.curl.*;
import org.unix.curl_h;
import static org.unix.curl_h.*;
import static org.unix.easy_h.*;
public class Main {
public static void main(String[] args) {
try (Scope s = curl_h.scope().fork()) {
curl_global_init(CURL_GLOBAL_DEFAULT);
Pointer<Void> curl = curl_easy_init();
if(!curl.isNull()) {
Pointer<Byte> url = s.allocateCString(args[0]);
curl_easy_setopt(curl, CURLOPT_URL, url);
int res = curl_easy_perform(curl);
if (res != CURLE_OK) {
System.err.println("Error fetching from: " + args[0] + " ERR: " + Pointer.toString(curl_easy_strerror(res)));
curl_easy_cleanup(curl);
}
}
curl_global_cleanup();
}
}
}
A couple of things to point out here. Notice how we cannot directly pass a Java String
to the curl_easy_setopt()
call. This call accepts a memory address pointer as the url
parameter, so we first need to do a dynamic memory allocation operation using the Scope
and pass a Pointer
interface instance instead. As you may find in the Panama tech docs [5], the Pointer
interface helps a lot when it comes to complex C-alike pointer operations like pointer arithmetic, casts, memory dereference, etc. The Scope
manages the runtime life-cycle of dynamic allocated memory.
Alright, now armed with this knowledge, can you extend this code to write the contents of a Curl fetched web page to a file stream?
Here’s a more complete example application that utilizes libSSH2 [4] to implement a simple SSH client.
If you’d like to have a go and adjust it to run on Windows, I’ll greatly appreciate a PR.
A few points from my side that I learned or have been thinking about while working with Panama.
Scope
is pretty powerful. You can allocate callback pointers, structs, arrays. The concept of layouts and layout types deserves more time for me to fully explore and grasp.Void
argument types. The Foreign Docs [3] have an example about this case when using the TensorFlow C API.Thanks for reading!🍻


Usage:
package require TJC
TJC::package package
TJC::command procname
classname
TJC::compile cmd
TJC is implemented as part of Jacl and includes runtime
support for TJC compiled procedures. The TJC package is loaded into
Jacl via the following Tcl command:
% package require TJC
1.0
The
TJC package defines
the
TJC namespace and
adds three Tcl commands to the
TJC
namespace. The
TJC::package
command is used to load a TJC compiled package into the Jacl
interpreter. Loading a TJC compiled package will source each of the Tcl
scripts included in the package and define each of the compiled Tcl
commands included in the package. In the following example, a TJC
compiled package named
foo.bar.baz
is loaded.
% TJC::package foo.bar.baz
A TJC package is initialized by loading a class named
TJCExtension from the named
package. This class implements the standard Extension API for Jacl
extensions, so one could also load a TJC package via the
java::load command as follows:
% java::load
foo.bar.baz.TJCExtension
The benefit of the
TJC::package
command is that it is simpler and it can be used even when the
java package has not been
loaded into Jacl.
The
TJC::command Tcl
command is normally used only by the internal implementation of TJC.
End users will not need to invoke the this command. The command is used
to associate a Tcl command name with a compiled Java class file. When a
Tcl script is parsed, it is scanned for proc declaration that can be
compiled. The code for compiled proc declarations is then replaced with
a call to
TJC::command.
Original Tcl Script:
set i 0
proc hello {}
{ return "Hello World" }
Modified Tcl Script:
set i 0
TJC::command
hello foo.bar.baz.HelloCmd
At runtime, a
[TJC::package
foo.bar.baz] command would cause the modified Tcl script to be
evaluated. The modified Tcl script would define the
hello command using the
compiled implementation in the Java class named
HelloCmd.
Compiling Tcl procs at runtime
Support for compiling Tcl procedures at runtime is included as part of
the TJC package. Using
TJC::compile,
one can compile a Tcl proc into Java source code and then into Java
byte code. The Java byte code implementation of the command will then
be loaded into the interpreter. Note that this runtime compilation is
not started by default and there is no means to automatically compile
all Tcl procs that are defined in the interpreter. The user needs to
explicitly indicate which procs should be compiled after the procs have
been defined. The most simple usage is the following.
package require TJC
proc hello {} {
return "Hello
World"
}
TJC::compile hello
The above invocation will start a second thread to do the compilation.
When the command has been compiled, the Tcl proc hello will be replaced
with a compiled version that performs the same operations as the Tcl
proc. Most users will only ever need to use the
TJC::compile command as shown
above.
In the example above, the user has no way of knowing when the compile
job is finished. If the user needs to be informed when the compile job
is done, the
TJC::compile
command supports notification via a callback or via a variable. The
following shows how a callback can be invoked when a compile job is
done.
package require TJC
proc hello {} {
return "Hello
World"
}
proc my_hello_ready { status cmd
msg } {
if {$status ==
"OK"} {
puts "command \"$cmd\" was compiled"
} else {
puts "command \"$cmd\" could not be compiled: $msg"
}
}
TJC::compile hello -readycmd
my_hello_ready
(after waiting a moment, the
following should be printed)
command "::hello" was compiled
In the example above, the callback is invoked with a status string that
can be "OK" or "ERROR". The cmd argument is the fully qualified name of
the compiled command. The msg argument is a string indicating a
compiler error if status is not "OK".
In following example, notification is implemented with a variable. The
example sets a variable when the command has been compiled and
installed. The value that the ready variable is set to is the same as
the arguments to the
-readycmd
command.
package require TJC
proc hello {} {
return "Hello
World"
}
TJC::compile hello -readyvar
my_hello_ready
vwait my_hello_ready
puts $my_hello_ready
(after a moment, the following
should be printed)
OK ::hello {}
Compiling Java classes at runtime
TJC::command can also be
used to compile source code for a Java class into byte code at runtime.
This functionality makes it easy to add dynamic generation of Java code
to an application. It can be extremely powerfull when used with the
java package. The following example shows how a static Java method can
be compiled and invoked.
package require TJC
package require java
set jclass mytest.dynamic.Test1
set jsrc {
package mytest.dynamic;
public class Test1 {
public static
String call() {
return "CALLED";
}
}
}
set jinfo [list $jclass $jsrc]
TJC::compile -java $jinfo
-readyvar my_class_ready
vwait my_class_ready
puts $my_class_ready
(after a moment, the following should be printed)
OK mytest.dynamic.Test1 {}
(since the class has been loaded,
its methods can be invoked)
java::call mytest.dynamic.Test1 call
CALLED
Note that when
-java
is passed to
TJC::command,
either a
-readyvar or
-readycmd argument pair must
also be passed. One or more classes generated from the Java class
declaration are loaded into the current class loader. Be aware that the
class loader can only load a given Java class once. Redefining or
unloading a class
is not supported. Also note that when a -readycmd or -readyvar
notification is done with a -java argument, the Java classes that were
loaded are passed in place of the cmd element.
