2. Структуры должны содержать марку авто, год выпуска, объем багажника/кузова, запущен ли двигатель, открыты ли окна, заполненный объем багажника.
3. Описать перечисление с возможными действиями с автомобилем: запустить/заглушить двигатель, открыть/закрыть окна, погрузить/выгрузить из кузова/багажника груз определенного объема.
4. Добавить в структуры метод с одним аргументом типа перечисления, который будет менять свойства структуры в зависимости от действия.
5. Инициализировать несколько экземпляров структур. Применить к ним различные действия.
6. Вывести значения свойств экземпляров в консоль.

何冲道：“但宫内戒备森严，勾魂仙娘又是个极难缠的女人，不如你我里应外合，容易得手。”
鬼偷想了一会，问道：“分宫里可有什么厉害的机关消息吗？”
何冲道：“机关井不可畏，但宫里养着两头异种雪拂，嗅觉极敏，夜间放出陷藏在树上，任是轻功多高的人，也瞒不过雪拂耳目，两头畜牲都有一人高，力大无穷，窜跃又灵活，颇难应付。”
鬼偷邢彬哂笑道：“区区两头畜牲，谅也难不倒老偷儿，咱们还是凭真工夫干吧，犯不上以身试险了。”
何冲道：“水中技艺，小弟或堪使用，陆上丁夫，自知难与邢老哥比拟，反正小弟已经帮不了老哥大忙，何妨去碰碰运气，她许倒能获得方便，助老哥成功。”
鬼偷邢彬道：“你一定要去，老偷儿也不便拦阻，但如因此闹出意外，譬如受到折伤，却不好对帮主交待。”
何冲毅然道：“任何后果，小弟愿一身承当，死亦无憾，决不连累老哥受责就是了。”
鬼偷邢彬无可奈何地道：“好吧！咱们就照你的意思试试，不过，你得答应老偷儿一件事，假如不幸失算，万不可徒逞意气，招致杀身之祸，总须忍耐待机，帮主一到，不难救你脱险二老偷地说句不怕难为情的话，除了手上工夫和轻功尚足自负，要我真刀真枪，只怕救不了你，反把自己也一井断送了。”
何冲大笑起来，于是先将入山途径方向，宫中房舍位置，大略对鬼偷解说一遍，两人才起身步出酒楼。
鬼偷邢彬寻了一家客栈，寄妥马匹，又购备了足够的干粮及应用工具的物件，最后，更买了两壶烈酒，配了几色药物，一切齐全，才随着何冲向城西而来。
两人一前一后，故作不识，何冲仍然乘马，鬼偷却徒步遥遥跟在后面五大开外，尾随而行。
何冲按辔径往城西，直到城门附近一家药材铺前下马，缓步踱进店里，向柜台中伙计道；“有上等的何首乌没有广
伙计微微一怔，忙笑道：“有！客官要多少？”
何冲道：“五百斤。”
伙计更讶，笑道：“要这么多？敢问作什么用途的？”
何冲漫声道：“做引子用。”
伙计笑道：“药引子何须这么多，有五两就足够了，不过，小店的药材全是最上等药材，价钱贵一些，而且现钱现货，谢绝欠账，请客官多原谅。”
何冲微微一笑，取出一样东西递给那伙计，道：“这块银子够了吗？”
伙计低头一看，竞是一面银牌，牌卜镶着“金陵分坛坛主”六个字，脸色顿时变得凝重，恭恭敬敬道：“客官请稍候。”随即匆匆转人店后去了。
鬼偷邢彬远远站在对街阴暗处，凝神倾注，私下不期替何冲捏着一把冷汗。
片刻之后，那伙计含笑而出，侧身道：“请客官后面看看货色！”
何冲略一颔首，昂然迈步走了进去。
穿过两层院落，一间敞厅中笑着迎出一个面貌清瘦的青衣老人，抱拳道：“何坛主来得正好，快请进来，今天真是幸会，先后竟到了两位贵宾。”
何冲认识那青衣老人姓马名文魁，号称“追魂郎中”，正是负责接待第五分宫往来访客的首席护法，论地位，不在分宫宫主之下，连忙拱手肃容道：“属下冒昧，请护法海涵。”
追魂郎中马文魁哈哈笑道：“自家人，千万别客套，请还请不到呢，何坛主试猜一猜老配所说还有一位贵宾是谁？
何冲摇头笑道：“属下哪里猜得到，不知是否总宫有人来厂？”
马文魁抚掌大笑道：“好精明！竟被你一猜就猜中啦！
何冲一面跟随马文魁走进敞厅侧客室，一面却心里忑忐不c，试探着问道：“总宫专使来到，必有要事，但不知来的是哪一位？
马文魁道：“正是有件要事，而目，这事还应在何坛主身上
何冲骇然一震，猛地却步，诧问道：“真的？属下有什么事，值得总宫特派专使赶来？”
马文魁笑道：“瞧你竟急成这样，欲知详情，何不当面一问？快请吧！老朽等着向你贺喜了。”
何冲本已情虚，正欲提聚真力抢先下手，听了最后一句话，不觉又暗暗松下一口气，讶问道：“属下何喜何贺？”
马文魁故作神秘笑道：“天机不可泄漏，且请室中详谈。”说着，笑盈盈亲手掀起客室垂帘，侧身肃客。”
何冲满腹疑云，略一沉吟，便壮胆举步而人，谁知一脚跨进室门，顿时惊噫出声，眼中几乎冒出怒火来……
原来客室中正悠然坐着一个三十岁左右，剑眉朗目，唇红齿白，黄姿奕奕的俊美书生。
那书生身穿一件蜀锦缎的儒衫，神采飞扬，堪称翩翩浊世佳公子，唯一美中不足的是那一双闪烁的眼神，包含着太多的狡猾，邪恶和淫凶。
他，正是曹克武的第四位爱徒，也就是何冲的夺妻仇人“玉面郎君”司马青臣。
仇人见面，价外眼红，何冲怒从心起，几乎就想拔剑出手，狠狠在那色魔身上，戳他几个血淋淋的窟窿。
但理智却告诉他不能轻举妄动，自己的辱妾仇恨同然重要，为卧龙庄上取回刀剑却更为重要，何况身在虎窟，追魂郎中和司马青臣武功都非比寻常，尤其司马青臣可算得是阿儿汗宫有数高手之一，倘若一击不成，自己生死事小，破坏了盗剑计谋，怎能对得起卧龙庄主桑琼？
何冲像貌看似赳赳武失，心思却极缜密，意念电转，终于把满腔怒火强自压抑厂下去，深深吸了一口气，藉着轻噫之声，假作惊喜之色，抢近一步，拱手道：“想不到竞是司马少侠亲莅，贵宾！果然是难得的贵宾……”
随着一阵哈哈大笑，司马青臣也从座椅中站起身米，亲切地拉住何冲手臂，笑道：“何兄！大喜大喜！小弟是奉宫主亲谕，特来向何见贺喜的！”
何冲微怔道：“属下不知喜从何来？”
司马青臣笑道：“龙剑风刀得手，既获千金重赏，又刻日荣升第五分宫副宫主要职，这还不算天大的喜讯么？”
何冲恍然一哦，忙道：“原来为这个，属下只是略尽本份，托宫主洪福，诸位同门鼎助，侥幸得手，怎敢居功？宫主实在褒赐太厚了。”
追魂郎中马文魁哈哈大笑道：“何兄太谦了，若非绝世身手，怎能于强敌云集之际，取得神兵利剑，老朽秃为地主，略备水酒一来替二位接风洗尘，二来为何兄荣升致贺，请人席再慢慢谈吧！”

# 1.Cú pháp
```
iptables [-t table] command [chain] [match] [target/jump]
```
\- Thứ tự các tham số có thể thay đổi nhưng cú pháp trên là dễ hiểu nhất.
\- Nếu không chỉ định `table`, mặc định sẽ là table filter.
\- `command` sẽ chỉ định chương trình phải làm gì.
VD: Insert rule hoặc thêm rule đến cuối của chains.
\- `chain` phải phù hợp với `table` được chỉ định.
\- `match` là phần của rule mà chúng ta gửi cho kernel để biết chi tiết cụ thể của gói tin, điều gì làm cho nó khác với các gói tin khác.
VD: địa chỉ IP, port, giao thức hoặc bất cứ điều gì.
\- Cuối cùng là `target` của gói tin. Nếu phù hợp với match, chúng tôi sẽ vói với kernel phải làm những gì với gói tin này.
<a name="2"></a>
# 2.Command
\- command nói cho iptables biết phải làm gì với phần còn lại của rule. Thông thường chúng ta muốn thêm hoặc xóa 1 cái gì đó trong bảng. Các command sau có sẵn trong iptables.
\- **command**
|Command|Ví dụ|Ý nghĩa|
|---|---|---|
|-A, --append|iptables -A INPUT|thêm rule vào cuối của chains.|
|-D, --delete|iptables -D INPUT --dport 80 -j DROP **hoặc** iptables -D INPUT 1|xóa rule của chain. Điều này có thể được thực hiện theo 2 cách; bằng cách nhập cả rule để khớp (như trong vd đầu tiên), hoặc bằng cách chỉ định số thứ tự của rule mà bạn muốn xóa. Các rules được đánh số từ đầu đến cuối đối với mỗ chain, bắt đầu với số thứ tự 1.|
|-R, --replace|iptables -R INPUT 1 -s 192.168.0.1 -j DROP|thay thế rule cũ tại dòng chỉ định. Nó sẽ làm việc tương tự như câu lệnh --delete, nhưng thay vì xóa, nó sẽ thay thế nó bằng mục nhập mới.|
|-I, --insert|iptables -I INPUT 1 --dport 80 -j ACCEPT|Insert rule vào chain. Rule được insert vào như rule đầu tiên. Nói cách khác, trong ví dụ trên, rule sẽ được chèn vào làm rule 1 trong chain INPUT.|
|-L, --list|iptables -L INPUT|Liệt kê tất cả các rules trong chain chỉ định. Nếu không chỉ định chain, nó sẽ liệt kê tất cả các chain trong table. Đầu ra phụ thuộc bởi các tùy chọn khác như tùy chọn -n và -v, …|
|-F, --flush|iptables -F INPUT|xóa tất cả các rule trong chain chỉ định trong bảng chỉ định.|
|-Z, --zero|iptables -Z INPUT|This command tells the program to zero all counters in a specific chain, or in all chains.|
|-N, --new-chain|iptables -N allowed|Câu lệnh nói với kernel tạo chain mới với tên được chỉ định trong table chỉ định. Trong ví dụ trên, chúng ta tạo chain được gọi là allowed. Tên của chain mới không được giống tên của chain và target đã tồn tại.|
|-X, --delete chain|iptables -X allowed|Xóa chain được chỉ định từ tables. Bạn phải xóa tất cả các rule của chain trước khi xóa chain. Nếu lệnh này sử dụng với không tùy chọn, tất cả các chains được xây dựng sẽ bị xóa.|
|-P, --policy|iptables -P INPUT DROP|Câu lệnh nói với kernel để thiết lập target mặc định, hoặc policy của chain. Tất cả các gói tin không phù hợp với bất kỳ rule nào sẽ bị buộc phải sử dụng policy của chain. Target thường là DROP hoặc ACCEPT.|
|-E, --rename-chain|iptables -E allowed disallowed|Câu lệnh nói với iptables rằng cần thay đổi tên của chain. VD trên, tên chain được thay đổi từ **allowed** đến **disallowed**. Chú ý: Điều này sẽ không ảnh hướng đến phương thức thực tế của tables sẽ làm việc.|

|-v, --verbose|--list, --append, --insert, --delete, --replace|- Lệnh thường được sử dụng với tùy chọn **--list**. Nếu được sử dụng với tùy chọn **--list**, output sẽ là các địa chỉ interface, tùy chọn của rule và TOS masks. Lệnh **--list** cũng bao gồm bộ đếm bytes và gói tin cho mỗi rule, nếu tùy chọn **--verbose** được thiết lập. Bộ đếm sử dụng hệ số nhân K (x1000), M(x1000.000) và G (x1000.000.000). Để nhận kết quả chính xác bạn có thể sử dụng tùy chọn **-x**.|

|Math|Ví dụ|Ý nghĩa|
|---|---|---|
|-p, --protocol|iptables -A INPUT -p tcp|math này được sử dụng để kiểm tra giao thức. VD của protocols là TCP, UDP và ICMP. Giao thức phải là 1 trong các chỉ định TCP, UDP và ICMP. Nó cũng có thể là các giá trị được chỉ định trong file `/etc/protocols`. VD: giao thức ICP là giá trị 1, TCP là 6 và UDP là 17. Nó cũng có thể lấy giá trị **ALL**, **ALL** có nghĩa là nó phù hợp TCP, UDP và ICMP. lệnh này cũng có thể lấy 1 danh sách các giao thức được phân cách bởi dấu phẩy, như **udp,tcp**. math có thể sử dụng kí tự !. VD: --protocol ! tcp có nghĩa là để phù hợp với UDP và ICMP.|
|-s, --src, --source|iptables -A INPUT -s 192.168.1.1|Đây là so sánh nguồn, dựa trên địa chỉ IP nguồn. Nó có thể được sử dụng để so sánh 1 địa chỉ IP hoặc 1 dải địa chỉ IP. VD về 1 địa chỉ IP : 192.168.1.1 . VD về 1 dải địa chỉ IP: 192.168.0.0/24 hoặc 192.168.0.0/255.255.255.0. VD về số sánh đảo ngược: --source ! 192.168.0.0/24 , sẽ so sánh tất cả các gói tin với địa chỉ IP nguồn không đến từ dải 192.168.0.x.|
|-d, --dst, --destination|iptables -A INPUT -d 192.168.1.1|Đây là so sánh đích, dựa trên địa chỉ IP đích. Nó có thể được sử dụng để so sánh 1 địa chỉ IP hoặc 1 dải địa chỉ IP. VD về 1 địa chỉ IP : 192.168.1.1 . VD về 1 dải địa chỉ IP: 192.168.0.0/24 hoặc 192.168.0.0/255.255.255.0. VD về số sánh đảo ngược: --destination ! 192.168.0.1 , sẽ so sánh tất cả các gói tin với địa chỉ IP đích không phải 192.168.0.1.|
|-i, --in-interface|iptables -A INPUT -i eth0|So sánh này được sử dụng cho interface gói tin đến. Tùy chọn này chỉ sử dụng cho các chain INPUT, FORWARD và PREROUTING. Nếu interface không được chỉ định, nó sử giả trị giá trị là dấu +. Dấu + được sử dụng để khớp với với 1 chuỗi chữ cái và số, điều này có nghĩa là chấp nhất tất cả các gói tin mà xem xét nó đến interface nào. Dấu + cũng có thể được nối vào interface, **eth0+** sẽ là tất các thiết bị Ethernet. Chúng ta có thể đảo ngược ý nghĩa của tùy chọn với dấu !. VD: -i ! eth0 sẽ phù hợp với tất cả gói tin đến từ các interface, ngoại trừ eth0.|
|-o, --out-interface|iptables -A FORWARD -o eth0|So sánh này được sử dụng cho interface gói tin rời đi. Tùy chọn này chỉ sử dụng cho các chain OUTPUT, FORWARD và POSTROUTING. Nếu interface không được chỉ định, nó sử giả trị giá trị là dấu +. Dấu + được sử dụng để khớp với với 1 chuỗi chữ cái và số, điều này có nghĩa là chấp nhất tất cả các gói tin mà xem xét nó rời đi từ interface nào. Dấu + cũng có thể được nối vào interface, **eth0+** sẽ là tất các thiết bị eth. Chúng ta có thể đảo ngược ý nghĩa của tùy chọn với dấu !.

### 3.2.1.TCP matches
|Match|Ví dụ|Ý nghĩa|
|---|---|---|
|--sport, --source-port|iptables -A INPUT -p tcp --sport 22|So sánh **--source-port** được sử dụng để só sánh sựa trên port nguồn. Math này có thể lấy tên dịch vụ hoặc số port. Nếu bạn chỉ định tên dịch vụ, tên dịch vụ phải trong file `/etc/services`, **iptables** sẽ sử dụng file này để tìm. Nếu chỉ định port bởi số, rule sẽ tải nhanh hơn, **iptables** không phải kiểm tra tên dịch vụ. Bạn có thể sử dụng **--source-port** để chị định 1 dải **ports**, **--source-port 22:80**. Nếu bạn không chỉ định port đầu, mặc định sẽ là port 0, **--source-port :80** sẽ là port từ 0 -> 80. Nếu không chỉ định port cuối, mặc định sẽ là port là 65535, **--source-port 22:**. Nếu bạn viết **--source-port 80:22**, nó tương đường với **--source-port 22:80**. Bạn có thể đảo ngược so sánh bằng cách thêm dấu !. VD: **--source-port ! 22** nghĩa là tất cả các ports nhưng không phải port 22. hoặc **--source-port ! 22:80**|
|--dport, --destination-port|iptables -A INPUT -p tcp --dport 22|math này được sử dụng cho gói tin TCP, theo port đích. Cú pháp tương tự **--source-port**|

## Introduction
The goal of the Summit Software INSPIRE is to provide a consistent software stack
for BIP178 project members. Note however, we are not an authoritarian project and you can
use whatever software you desire.
## First steps
Run the following command:
** source /gpfs/alpine/proj-shared/bip178/Inspire_Project_Software/bin/summit_inspire_environmental_variables.sh **
This will set two key environmental variables and modify your module file path to make the
Summit INSPIRE binaries available. The 2 key environmental variables are
* INSPIRE_TARGET_MACHINE
* INSPIRE_PROJECT_SOFTWARE_TOP_LEVEL
## Loading Software
One should now be able to load the Summit INSPIRE software. Do the following command to see what
is available
** module avail Summit **
### Core Software Stack
The core software sets the environment for the gcc compiler, swig, python, and other software
to build and run in an consistent environment.
To load the core software stack do
** module load Summit/inspire_project_environment **
This command need only be done once.
### Production Software
To load a production software load the core software module then load the desired module. For
example to load AutoDock Vina do the following
** module load Summit/inspire_project_environment **
** module load Summit/autodock_vina/1.1.2 **
Recall that one need only to load the core software stack once. |

A really thought provoking article on irrational politics — and you're probably thinking of _irrational_ in an entirely pejorative way, but here it means a politics that uses symbols and myths rather than “facts” and arguments. Knausgaard contemplates the appeal of Nazism to Germans in its symbols and philosophical promise to provide simplicity and _depth_, rather than as a response to the collapse of the Weimar Republic, mass unemployment and other economic and historical factors.
It strikes me that — at the very least — we need to understand this rather than see Trump, Brexit and other modern irrationalities simply in terms of a failure of reason.

summary: IAsyncEnumerable is a great new feature in C# 8. This post should help clarify what they do, when to use them, and when they can be used in a particular project.
---
{: .notice--info}
This blog is one of The December 1st entries on the [2019 C# Advent Calendar](https://crosscuttingconcerns.com/The-Third-Annual-csharp-Advent). Thanks for having me again Matt!
My favorite new feature in [C# 8](https://docs.microsoft.com/en-us/dotnet/csharp/whats-new/csharp-8) has got to be
[Asynchronous Streams](https://docs.microsoft.com/en-us/dotnet/csharp/whats-new/csharp-8#asynchronous-streams), a.k.a.
Asynchronous Enumerables. However, I think there may some confusion as to what they do, when to use them, and even if
they can be used in a particular project. This post will hopefully clarify some of these points.
## TL;DR
You can use `IAsyncEnumerable<T>` and the related C# 8 features in .NET Core 2.x or .NET Framework 4.6.1, not just .NET Core 3.0!
## Why use `IAsyncEnumerable<T>`?`
When writing efficient applications intended to handle large numbers of simultaneous operations, such as web applications,
blocking operations are the enemy. Any time an application is waiting on some kind of I/O-bound operation, such as a network
response or a hard disk read, it is always best to relinquish the thread back to the thread pool. This allows the CPU to
work on other operations while the method is waiting, and then continue the work once there is more to be done, without using up
all of the threads in the thread pool. Lots of details about why are
[available here](https://docs.microsoft.com/en-us/dotnet/standard/parallel-programming/task-based-asynchronous-programming).
In many cases, it's efficient enough to simply return a regular `IEnumerable<T>` asynchronously, like so:
```cs
public async Task DoWork()
{
var query = BuildMyQuery();
IEnumerable<XYZ> queryResult = await query.ExecuteAsync();
foreach (var item in queryResult)
{
// Do work here
}
}
```
However, this is may not be the most efficient approach. There are two potential limitations, depending on the backing implementation of
`ExecuteAsync` in the example above.
1. The implementation of ExecuteAsync may return after it gets the first part of the data, or even none. If it is enumerated faster than the data is arriving it will block waiting for more items to arrive. This will block the executing thread.
2. The implementation of ExecuteAsync may wait until it has **all** of the data before returning. This delays the point where DoWork may begin processing data.
`IAsyncEnumerable<T>` and its sibling `IAsyncEnumerator<T>`, on the other hand, return a `Task` as the stream is iterated. This allows methods
such as `ExecuteAsync` to return early and then wait for more data as it is iterated, without blocking the thread.
## When **Not** To Use IAsyncEnumerable
Don't use `IAsyncEnumerable<T>` for any collection which is inherently synchronous and CPU-bound.
For those cases, continuing using `IEnumerable<T>`. The extra overhead of handling asynchronous tasks
will usually be less performant in these scenarios.
Knowing which type to use as the return type on an interface method is a bit tricker. The interface can have different
backing implementations which may or may not be synchronous. In this case, use the pattern for the most likely scenario.
If in doubt, lean towards `IAsyncEnumerable<T>` because it can be used for either scenario and is therefore more flexible.
## Returning an IAsyncEnumerable in C# 8
For simple use cases, returning an `IAsyncEnumerable<T>` using an iterator function is as easy as an `IEnumerable<T>`.
```cs
public async IAsyncEnumerable<XYZ> GetXYZAsync() {
for (var i=0; i<20; i++)
{
var item = await GetXYZById(i);
yield return item;
}
}
```
It is also possible to write an iterator method which returns `IAsyncEnumerator<T>`.
If the method supports cancellation, the CancellationToken should to be decorated with the
`EnumeratorCancellation` attribute:
```cs
public async IAsyncEnumerable<XYZ> GetXYZAsync([EnumeratorCancellation] CancellationToken cancellationToken = default) {
for (var i=0; i<20; i++)
{
var item = await GetXYZById(i, cancellationToken);
yield return item;
}
}
```
## Consuming an IAsyncEnumerable in C# 8
To consume an IAsyncEnumerable, simply use the new `await foreach` statement within an asynchronous method.
```cs
await foreach (var item in GetXYZAsync())
{
// do things here
}
```
To control the synchronization context, `ConfigureAwait` is available, just like on `Task`.
```cs
await foreach (var item in GetXYZAsync().ConfigureAwait(false))
{
// do things here
}
```
To pass a cancellation token:
```cs
await foreach (var item in GetXYZAsync().WithCancellation(cancellationToken))
{
// do things here
}
```
## Special Compatibility Concerns
Depending on the type of project and the version of .NET being targeted, there may be concerns
about compatibility. One myth is that these features can only be used with .NET Core 3.0 and C# 8.
### Can I Use IAsyncEnumerable When Targeting .NET Core 2.x?
**Short answer**: Yes
To gain access to IAsyncEnumerable, install the compatibility NuGet package
[Microsoft.Bcl.AsyncInterfaces](https://www.nuget.org/packages/Microsoft.Bcl.AsyncInterfaces/). This provides
the types that are missing in .NET Standard 2.0.
However, producing and consuming IAsyncEnumerables is a bit more difficult. Here's an example consumer:
```cs
var enumerable = GetXYZAsync();
var enumerator = enumerable.GetAsyncEnumerator();
try
{
while (await enumerator.MoveNextAsync())
{
var item = enumerator.Current;
// Do things here
}
}
finally
{
await enumerator.DisposeAsync();
}
```
To get around this limitation, there are ways to access C# 8 language features, like asynchronous streams, even from .NET Core 2.x.
The requirements are:
- Use .NET Core SDK 3.0 or MSBuild Tools 2019 as the compiler.
- Use Visual Studio 2019 or VSCode as the IDE.
- Add a `<LangVersion>8</LangVersion>` property to the project file.
```xml
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFramework>netcoreapp2.0</TargetFramework>
<LangVersion>8</LangVersion>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="Microsoft.Bcl.AsyncInterfaces" Version="1.0.0" />
</ItemGroup>
</Project>
```
### Can I Use IAsyncEnumerable When Targeting .NET Framework
**Short answer**: Yes, 4.6.1 or later
.NET Framework 4.6.1 is compatible with .NET Standard 2.0. Therefore, so long as the project is targeting .NET Framework 4.6.1 or later,
the same rules apply as for .NET Core 2.x. Just follow the same steps as above.
### What About NuGet Packages?
**Short answer**: Yes, targeting .NET Standard 2.0 or later
When creating a NuGet package, maintaining backwards compatibility is key. This can make it difficult to use new features like
asynchronous streams. The good news is that there is a relatively easy path.
- Dual target .NET Standard 2.0 and 2.1.
- Consider targeting .NET 4.6.1 as well, see [Microsoft's guidance on cross platform targeting](https://docs.microsoft.com/en-us/dotnet/standard/library-guidance/cross-platform-targeting).
- Include [Microsoft.Bcl.AsyncInterfaces](https://www.nuget.org/packages/Microsoft.Bcl.AsyncInterfaces/) for the lower version targets only.
- Add a `<LangVersion>8</LangVersion>` property to the project file.
```xml
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFrameworks>net461;netstandard2.0;netstandard2.1</TargetFrameworks>
<LangVersion>8</LangVersion>
</PropertyGroup>
<ItemGroup Condition=" '$(TargetFramework)' == 'net461' Or '$(TargetFramework)' == 'netstandard2.0' ">
<PackageReference Include="Microsoft.Bcl.AsyncInterfaces" Version="1.0.0" />
</ItemGroup>
</Project>
```
However, this approach has problems if the package needs to target versions of .NET Core before 2.0, .NET Standard before 2.0,
or .NET Framework before 4.6.1. The `Microsoft.Bcl.AsyncInterfaces` package isn't compatible with frameworks prior these versions.
This can still be addressed by using preprocessor conditionals within the codebase to exclude `IAsyncEnumerable<T>` support,
but is much more cumbersome and outside the scope of this post.
## What about LINQ?
Most .NET developers love to use LINQ, either using the query syntax or using the functional
syntax like `.Where(p => p != null)` or `.Select(p => p.Property)`. Is it possible to use LINQ with `IAsyncEnumerable<T>`?
To get support for the functional LINQ syntax, such as `.Where(p => p != null)` or `.Select(p => p.Property)`, install
[System.Linq.Async](https://www.nuget.org/packages/System.Linq.Async/). This package is brought to us by the group that makes
[ReactiveX](http://reactivex.io/). Be sure to use at least version 4.0.0.
## Conclusion
Don't be afraid to use `IAsyncEnumerable<T>` in your code. It's really a lot more available than most developers think it is,
and is very easy to use.

Python | UTF-8 | 8,037 | 3.96875 | 4 | [] | no_license | #%% TensorFlow 变量是用于表示程序处理的共享持久状态的推荐方法。本指南介绍在 TensorFlow 中如何创建、更新和管理 tf.Variable 的实例。
#变量通过 tf.Variable 类进行创建和跟踪。tf.Variable 表示张量，对它执行运算可以改变其值。
# 利用特定运算可以读取和修改此张量的值。更高级的库（如 tf.keras）使用 tf.Variable 来存储模型参数。
#%% 1 设置
# 本笔记本讨论变量布局。如果要查看变量位于哪一个设备上，请取消注释这一行代码。
import tensorflow as tf
# Uncomment to see where your variables get placed (see below)
# tf.debugging.set_log_device_placement(True)
#%% 2 创建变量
# 要创建变量，请提供一个初始值。tf.Variable 与初始值的 dtype 相同。
my_tensor = tf.constant([[1.0, 2.0], [3.0, 4.0]])
my_variable = tf.Variable(my_tensor)
# Variables can be all kinds of types, just like tensors
bool_variable = tf.Variable([False, False, False, True])
complex_variable = tf.Variable([5 + 4j, 6 + 1j])
# 变量与张量的定义方式和操作行为都十分相似，实际上，它们都是 tf.Tensor 支持的一种数据结构。与张量类似，变量也有 dtype 和形状，并且可以导出至 NumPy。
# 大部分张量运算在变量上也可以按预期运行，不过变量无法重构形状。
print("A variable:",my_variable)
print("\nViewed as a tensor:", tf.convert_to_tensor(my_variable))
print("\nIndex of highest value:", tf.argmax(my_variable))
# This creates a new tensor; it does not reshape the variable.
print("\nCopying and reshaping: ", tf.reshape(my_variable, ([1,4])))
# 如上所述，变量由张量提供支持。您可以使用 tf.Variable.assign 重新分配张量。调用 assign（通常）不会分配新张量，而会重用现有张量的内存。
a = tf.Variable([2.0, 3.0])
# This will keep the same dtype, float32
a.assign([1, 2])
# Not allowed as it resizes the variable:
try:
a.assign([1.0, 2.0, 3.0])
except Exception as e:
print(f"{type(e).__name__}: {e}")
# 如果在运算中像使用张量一样使用变量，那么通常会对支持张量执行运算。
# 从现有变量创建新变量会复制支持张量。两个变量不能共享同一内存空间。
a = tf.Variable([2.0, 3.0])
# Create b based on the value of a
b = tf.Variable(a)
a.assign([5, 6])
# a and b are different
print(a.numpy())
print(b.numpy())
# There are other versions of assign
print(a.assign_add([2,3]).numpy()) # [7. 9.]
print(a.assign_sub([7,9]).numpy()) # [0. 0.]
#%% 3 生命周期、命名和监视
# 在基于 Python 的 TensorFlow 中，tf.Variable 实例与其他 Python 对象的生命周期相同。如果没有对变量的引用，则会自动将其解除分配。
# 为了便于跟踪和调试，您还可以为变量命名。两个变量可以使用相同的名称。
# Create a and b; they have the same value but are backed by different tensors.
a = tf.Variable(my_tensor, name="Mark")
# A new variable with the same name, but different value
# Note that the scalar add is broadcast
b = tf.Variable(my_tensor + 1, name="Mark")
print(a == b)
# 保存和加载模型时会保留变量名。默认情况下，模型中的变量会自动获得唯一变量名，所以除非您希望自行命名，否则不必多此一举。
# 虽然变量对微分很重要，但某些变量不需要进行微分。在创建时，通过将 trainable 设置为 False 可以关闭梯度。例如，训练计步器就是一个不需要梯度的变量。
step_counter = tf.Variable(1, name='Steps', trainable=False)
#%% 4 放置变量和张量
# 为了提高性能，TensorFlow 会尝试将张量和变量放在与其 dtype 兼容的最快设备上。这意味着如果有 GPU，那么大部分变量都会放置在 GPU 上。
# 不过，我们可以重写变量的位置。在以下代码段中，即使存在可用的 GPU，我们也可以将一个浮点张量和一个变量放置在 CPU 上。
# 通过打开设备分配日志记录（参阅设置），可以查看变量的所在位置。
# 注：虽然可以手动放置变量，但使用分布策略是一种可优化计算的更便捷且可扩展的方式。
with tf.device('CPU:0'):
# Create some tensors
a = tf.Variable([[1.0, 2.0, 3.0], [4.0, 5.0, 6.0]])
b = tf.constant([[1.0, 2.0], [3.0, 4.0], [5.0, 6.0]])
c = tf.matmul(a, b)
print(c)
# 您可以将变量或张量的位置设置在一个设备上，然后在另一个设备上执行计算。但这样会产生延迟，因为需要在两个设备之间复制数据。
# 不过，如果您有多个 GPU 工作进程，但希望变量只有一个副本，则可以这样做。
with tf.device('CPU:0'):
a = tf.Variable([[1.0, 2.0, 3.0], [4.0, 5.0, 6.0]])
b = tf.Variable([[1.0, 2.0, 3.0]])
with tf.device('GPU:0'):
# Element-wise multiply
k = a * b
print(k)
# 注：由于 tf.config.set_soft_device_placement 默认处于打开状态，所以，即使在没有 GPU 的设备上运行此代码，它也会运行，只不过乘法步骤在 CPU 上执行。
#%% Part 2 自动微分和梯度带 - 梯度带
# 在上一个教程中，我们介绍了 "张量"（Tensor）及其操作。本教程涉及自动微分（automatic differentitation），它是优化机器学习模型的关键技巧之一。
# TensorFlow 为自动微分提供了 tf.GradientTape API ，根据某个函数的输入变量来计算它的导数。
# Tensorflow 会把 'tf.GradientTape' 上下文中执行的所有操作都记录在一个磁带上 ("tape")。 然后基于这个磁带和每次操作产生的导数，
# 用反向微分法（"reverse mode differentiation"）来计算这些被“记录在案”的函数的导数。
x = tf.ones((2, 2))
with tf.GradientTape() as t:
t.watch(x)
y = tf.reduce_sum(x)
z = tf.multiply(y, y)
# Derivative of z with respect to the original input tensor x
dz_dx = t.gradient(z, x)
for i in [0, 1]:
for j in [0, 1]:
assert dz_dx[i][j].numpy() == 8.0
# 你也可以使用 tf.GradientTape 上下文计算过程产生的中间结果来求取导数。
x = tf.ones((2, 2))
with tf.GradientTape() as t:
t.watch(x)
y = tf.reduce_sum(x)
z = tf.multiply(y, y)
# Use the tape to compute the derivative of z with respect to the
# intermediate value y.
dz_dy = t.gradient(z, y)
assert dz_dy.numpy() == 8.0
#%% 默认情况下，调用 GradientTape.gradient() 方法时， GradientTape 占用的资源会立即得到释放。通过创建一个持久的梯度带，可以计算同个函数的多个导数。
# 这样在磁带对象被垃圾回收时，就可以多次调用 'gradient()' 方法。例如：
x = tf.constant(3.0)
with tf.GradientTape(persistent=True) as t:
t.watch(x)
y = x * x
z = y * y
dz_dx = t.gradient(z, x) # 108.0 (4*x^3 at x = 3)
dy_dx = t.gradient(y, x) # 6.0
del t # Drop the reference to the tape
#%% 2 记录控制流
# 由于磁带会记录所有执行的操作，Python 控制流（如使用 if 和 while 的代码段）自然得到了处理。
def f(x, y):
output = 1.0
for i in range(y):
if i > 1 and i < 5:
output = tf.multiply(output, x)
return output
def grad(x, y):
with tf.GradientTape() as t:
t.watch(x)
out = f(x, y)
return t.gradient(out, x)
x = tf.convert_to_tensor(2.0)
assert grad(x, 6).numpy() == 12.0
assert grad(x, 5).numpy() == 12.0
assert grad(x, 4).numpy() == 4.0
#%% 3 高阶导数
# 在 'GradientTape' 上下文管理器中记录的操作会用于自动微分。如果导数是在上下文中计算的，导数的函数也会被记录下来。
# 因此，同个 API 可以用于高阶导数。例如：
x = tf.Variable(1.0) # Create a Tensorflow variable initialized to 1.0
with tf.GradientTape() as t:
with tf.GradientTape() as t2:
y = x * x * x
# Compute the gradient inside the 't' context manager
# which means the gradient computation is differentiable as well.
dy_dx = t2.gradient(y, x)
d2y_dx2 = t.gradient(dy_dx, x)
assert dy_dx.numpy() == 3.0
assert d2y_dx2.numpy() == 6.0

title: Строки
permalink: topics/string/
---
**Строка** в C++ представляет собой особый класс. Класс, в терминах программирования, это элемент, описывающий абстрактный тип данных. Это означает, что для строки определены особые функции - методы.
Чтобы пользоваться строками, необходимо подключить заголовочный файл <string>:
{% highlight cpp %}
#include <string>
{% endhighlight %}
Объявление строк схоже с объявлением переменной.
{% highlight cpp %}
#include <iostream>
#include <string>
using namespace std;
int main()
{
string s;
s = "Hello!";
cout << s << endl;
return 0;
}
{% endhighlight %}
Строка также представляет собой массив символов. Значит, чтобы получить конкретный символ, можно использовать следующее:
{% highlight cpp %}
#include <iostream>
#include <string>
using namespace std;
int main()
{
string s;
s = "Hello!";
cout << s[2] << endl;
return 0;
}
{% endhighlight %}
Этот код выведет третий символ строки s.
## Методы string
Для начала следует сказать, что для строки определены итераторы **begin()** и **end()**. Указывающие соответственно на первый и на последний символы.
* **s.size() / s.lenght()**
Возвращает длину строки s. В следующем коде мы циклом идем по строке и выводим каждый символ.
{% highlight cpp %}
#include <iostream>
#include <string>
using namespace std;
int main()
{
string s;
cin >> s;
for (int i = 0; i < s.size(); i++)
{
cout << s[i];
}
return 0;
}
{% endhighlight %}
* **s.append(s1)**
Данная функция добавляет строку s1 в конец строки s.
{% highlight cpp %}
#include <iostream>
#include <string>
using namespace std;
int main()
{
string s = "a";
string s1 = "b";
s.append(s1); // идентично s += s1
cout << s << endl;
cout << s + s1 << endl;
return 0;
}
{% endhighlight %}
* **s.erase()**
Данная функция имеет несколько перегрузок:
| s.erase(pos,n)| удаляет n символов начиная с позиции pos |
| s.erase(iterator) | iterator - это итератор, указывающий на символ. В результате применения функции этот символ будет удален|
| s.erase(it begin, it end) | it begin, it end - итераторы, указывающие на начало и конец удаляемой последовательности |
{% highlight cpp %}
#include <iostream>
#include <string>
using namespace std;
int main()
{
string s = "abcdef";
s.erase(1,2); // adef
string str = "abcdef";
str.erase(str.begin()); // bcdef
string sp = "abcdef";
sp.erase(sp.begin() + 1, sp.end()); // a
}
{% endhighlight %}
В данном коде показаны преобразования строки, сделанные erase().
* **s.find(ch)**
Возвращает позицию, с которой ch входит в s. В свою очередь ch может быть отдельным символом или строкой. Если ch не найдено, возвращает string::npos.
* **s.substr(pos,n)**
Возвращает подстроку из n символов начиная с позиции pos.
* **Перевод строки в число и наоборот**
Когда возникает потребность перевести число в строку, может пригодиться функция stoi:
{% highlight cpp %}
string s;
cin >> s;
int n = stoi(s);
cout << n;
{% endhighlight %}
Если же нам нужно перевести число в строку, воспульзуемся функцией to_string:
{% highlight cpp %}
int n;
cin >> n;
string s = to_string(n);
cout << s;
{% endhighlight %}
## Символьные функции
Иногда нам нужно отвечать на вопрос: а является ли символ буквой, цифрой, знаком пунктуации etc? Тогда нам могут помочь символьные функции. Они принимают на вход символ и возвращают логическое значение.
| isalpha(char) | true, если буква |
| ispunct(char) | true, если знак пунктуации |
| isdigit(char) | true, если десятичная цифра |
| isspace(char) | true, если пробел |
| islower(char) | true, если символ нижнего регистра |
| isupper(char) | true, если символ вернего регистра |
| tolower(char) | возвращает char в нижнем регистре |
| toupper(char) | возвращает char в верхнем регистре |
## Решение задачи : проверка на палиндромность
Создадим логическую функцию, с помощью которой будем определять, является ли строка палиндромом. Напомним, что палиндром - строка, которая читается одинаково с начала и с конца. Например, abba - палиндром.
{% highlight cpp %}
bool palindrome(string s)
{
for (int i = 0; i < s.size() / 2; i++)
if (s[i] != s[s.size() - 1 - i])
return false;
return true;
}
{% endhighlight %}
