您可以返回类似

a.option.localeCompare(b.option) * 2 - 1;

比较的东西,哪个字符串以“较高”字母开头。

(由于功能返回0或1,因此需要 * 2-1)

You could return something like

a.option.localeCompare(b.option) * 2 - 1;

which compares, which string starts with the "higher" letter.

(Since the functions returns 0 or 1 the * 2 - 1 is needed)

sort()方法用于类似值

据我所知,您希望所有具有2-4个状态的数据,并且是否状态为5,而不是检查 create_at> = 2022-06-01和name ='abc'

    $query = TableName::whereBetween('status', [2, 4])
    ->orWhere('status', '>', 5)
    ->orWhere(function($q) {
        $q->where('status', 5)
          ->whereDate('created_at', '>=', date('2022-06-01'));
    })
    ->get();

As I understand that you want all data with status between 2-4 and if status is 5 than check if created_at >=2022-06-01 AND NAME='ABC'.

    $query = TableName::whereBetween('status', [2, 4])
    ->orWhere('status', '>', 5)
    ->orWhere(function($q) {
        $q->where('status', 5)
          ->whereDate('created_at', '>=', date('2022-06-01'));
    })
    ->get();

OPENSL语句在PKCS#8格式中生成一个私钥,并以X.509/SPKI格式的公共密钥进行了PEM编码。

使用GO代码生成的私钥具有PKCS#8格式,但是PEM编码使用错误的标头和页脚(正确的标题和页脚将为 ------开始私有密钥------- -----结束私钥------ )。修复程序是在 encodeprivateKeyTopem()中调整 pem.block()相应地调用类型(类型:“ private键” )。

对于使用GO代码生成的公共密钥,情况是相反的:此处,标题和页脚对应于PEM编码的X.509/SPKKI密钥的标题。但是,身体是PKCS#1格式。这就是钥匙有所不同的原因。修复程序是在 encodepublicKeyTopem()中使用X.509/SPKI格式而不是 MARSHALPKCS1PUBLICKEYKEKEY() mashalpkixpublickey()。

顺便说一句,检查密钥的最佳方法是使用ASN.1解析器,例如 https:// lapo。它/asn1js/

The OpenSSL statements generate a private key in PKCS#8 format and a public key in X.509/SPKI format, both PEM encoded.

The private key generated with the Go Code has the PKCS#8 format, but the PEM encoding uses the wrong header and footer (correct would be -----BEGIN PRIVATE KEY----- and -----END PRIVATE KEY-----). The fix is to adjust in EncodePrivateKeyToPEM() in the pem.Block() call the type accordingly (Type: "PRIVATE KEY").

In the case of the public key generated with the Go Code, the situation is reversed: Here, the header and footer correspond to those of a PEM encoded X.509/SPKI key. However, the body is PKCS#1 formatted. This is the reason why the keys differ. The fix is to use in EncodePublicKeyToPEM() the method MarshalPKIXPublicKey() for the X.509/SPKI format instead of MarshalPKCS1PublicKey().

By the way, the best way to inspect the keys is to use an ASN.1 parser, e.g. https://lapo.it/asn1js/.

看起来您有3个X值,每个值出现5、10或15次。您是否希望像现在一样,将条形覆盖在彼此的顶部?如果将alpha = 0.5添加到GEOM_COL调用中,您会看到重叠的条。

另外,您可能会使用躲避来显示彼此相邻的条形,而不是彼此之间。

ggplot(df, aes(x=x, y=y, fill=z, group = z)) + 
  geom_col(width=0.5, position=position_dodge()) +
  scale_fill_viridis_c(option="turbo", # added with ggplot 3.x in 2018
                     limits = c(0,10),
                     breaks=seq(0,10,2.5),
                     labels=c("0","2.5","5.0","7.5","10.0"))

或者您可以按 y 的顺序绘制数据,以便较小的条出现在顶部,明显:

ggplot(dplyr::arrange(df,y), aes(x=x, y=y, fill=z))+ 
  geom_col(width=0.5, position="identity") +
  scale_fill_viridis_c(option="turbo",
                     limits = c(0,10),
                     breaks=seq(0,10,2.5),
                     labels=c("0","2.5","5.0","7.5","10.0"))

It looks like you have 3 X values that each appear 5, 10, or 15 times. Do you want the bars to be overlaid on top of one another, as they are now? If you add an alpha = 0.5 to the geom_col call you'll see the overlapping bars.

Alternatively, you might use dodging to show the bars next to one another instead of on top of one another.

ggplot(df, aes(x=x, y=y, fill=z, group = z)) + 
  geom_col(width=0.5, position=position_dodge()) +
  scale_fill_viridis_c(option="turbo", # added with ggplot 3.x in 2018
                     limits = c(0,10),
                     breaks=seq(0,10,2.5),
                     labels=c("0","2.5","5.0","7.5","10.0"))

enter image description here

Or you might plot the data in order of y so that the smaller bars appear on top, visibly:

ggplot(dplyr::arrange(df,y), aes(x=x, y=y, fill=z))+ 
  geom_col(width=0.5, position="identity") +
  scale_fill_viridis_c(option="turbo",
                     limits = c(0,10),
                     breaks=seq(0,10,2.5),
                     labels=c("0","2.5","5.0","7.5","10.0"))

enter image description here

是否可以使用GGPLOT制作列图,其中列填充由第三个变量控制?

如果这对某人有帮助,我终于弄清楚了如何做到这一点。我使用的所有代码都在下面。注意:使用XML字符,因为我使用的是Blogger模板,该模板不允许'或> <标志。

   
$(document).ready(function() {
    // This will fire when document is ready:
    $(window).on('resize', function(){
        // This will fire each time the window is resized:
        if($(window).width() >= 1024) {
            // if larger or equal
        $('#book-carosel').slick({
        slidesToShow: 6,
        slidesToScroll: 1,
        autoplay: true,
        autoplaySpeed: 2000,
        arrows: true,
        infinite:true
   
      }).show();

             } else if ($(window).width() >= 800) {
            // if smaller
            $('#book-carosel').slick({
                slidesToShow: 4,
                slidesToScroll: 1,
                autoplay: true,
                autoplaySpeed: 2000,
               arrows: true,
               infinite:true
   
              }).show();
   
           } else if ($(window).width() >= 600) {
            // if smaller
            $('#book-carosel').slick({
                slidesToShow: 3,
                slidesToScroll: 1,
                autoplay: true,
                autoplaySpeed: 2000,
               arrows: true,
               infinite:true
   
              }).show();
   
        } else if ($(window).width() >= 300) {
            // if smaller
            $('#book-carosel').slick({
                slidesToShow: 2,
                slidesToScroll: 1,
                autoplay: true,
                autoplaySpeed: 2000,
               arrows: true,
               infinite:true
   
        
   
              }).show();
   
        } else {
  //  block of code to be executed if the condition1 is false and condition2 is false
            $('#book-carosel').unslick();
        }
    }).resize(); // This will simulate a resize to trigger the initial run.
});

In case this helps someone, I have finally figured out how to do this. All of the code I used is below. Note: XML characters were used since I am using a Blogger template, which doesn't allow ' or > < signs.

   
$(document).ready(function() {
    // This will fire when document is ready:
    $(window).on('resize', function(){
        // This will fire each time the window is resized:
        if($(window).width() >= 1024) {
            // if larger or equal
        $('#book-carosel').slick({
        slidesToShow: 6,
        slidesToScroll: 1,
        autoplay: true,
        autoplaySpeed: 2000,
        arrows: true,
        infinite:true
   
      }).show();

             } else if ($(window).width() >= 800) {
            // if smaller
            $('#book-carosel').slick({
                slidesToShow: 4,
                slidesToScroll: 1,
                autoplay: true,
                autoplaySpeed: 2000,
               arrows: true,
               infinite:true
   
              }).show();
   
           } else if ($(window).width() >= 600) {
            // if smaller
            $('#book-carosel').slick({
                slidesToShow: 3,
                slidesToScroll: 1,
                autoplay: true,
                autoplaySpeed: 2000,
               arrows: true,
               infinite:true
   
              }).show();
   
        } else if ($(window).width() >= 300) {
            // if smaller
            $('#book-carosel').slick({
                slidesToShow: 2,
                slidesToScroll: 1,
                autoplay: true,
                autoplaySpeed: 2000,
               arrows: true,
               infinite:true
   
        
   
              }).show();
   
        } else {

这个答案很复杂。但是,从我的手机上,RCS消息可以存储在带有所有SMS和MMS消息的 mmssms.db 文件中。 RCS消息似乎保存在与MMS消息相同的地方,但我不认为只能仅用于将其用于RCS消息的方法。因此,从理论上讲,如果您有 SMS阅读权限

话虽这么说,这可能是Google消息在使用JIBE服务器方面的表现,并且将来可能不会改变,并且在手机上也可能完全不同。

This answer is complicated. There are no public APIs for RCS, however, from what I can tell, on my phone, RCS messages are stored in the mmssms.db file with all of the SMS and MMS messages. RCS messages appear to be saved in there the same as MMS messages, but I don't believe there is a way to filter them for RCS messages only. So in theory you should be able to read them if you have SMS read permissions.

That being said, this may be unique to how Google Messages behaves with using Jibe servers, and may or may not change in the future, and also may be completely different on your phone.

目前是否可以阅读RCS消息的收件箱?

OpenPyXl将“主题颜色”和“标准颜色”视为单独的属性。
您可以通过做:

print("Cell fill display:" wb.active(rowNumber, columnNumber).fill)

这将显示出长的输出,其中包括与:相似的零件:

fgcolor =&lt; openpyxl.styles.colors.color object&gt;参数:rgb = none,
索引= none,auto = none,theme = 4,tint = 0.79998168888943144,
type ='主题',...

注意到RGB最终没有键入的是'主题'而不是'rgb'。

如果您希望使用“主题”而不是标准(RGB)颜色,则需要定义一个提取主题和色调的函数,然后将它们作为字符串或字典项目一起存储在一起。

wb.active(rowNumber, columnNumber).fill.fgColor.theme)
wb.active(rowNumber, columnNumber).fill.fgColor.tint)

OpenPyXl treats 'theme color' and 'standard color' as separate attributes.
You can test this for yourself by doing:

print("Cell fill display:" wb.active(rowNumber, columnNumber).fill)

This will show a long output including parts that looks similar to:

fgColor=<openpyxl.styles.colors.Color object> Parameters: rgb=None,
indexed=None, auto=None, theme=4, tint=0.7999816888943144,
type='theme', ...

Notice how rgb is None but type at the end is 'theme' instead of 'rgb'.

If you wish to utilize 'theme' instead of standard (rgb) color, you'll need need to define a function that extracts the theme and tint and then stores them together as a string or a dictionary item.

wb.active(rowNumber, columnNumber).fill.fgColor.theme)
wb.active(rowNumber, columnNumber).fill.fgColor.tint)

OpenPyXl Workbook主题颜色不是Excel的标准

我制作了此简单的 findID 方法,以找到标题并返回 id undefined 作为数据阵列结构的结果。

findid(标题,列表)函数。
其目的是迭代第二个参数中收到的列表,在每个元素中查找标题,如果有匹配项,则返回ID,否则检查是否在元素中和元素中检查 subs 这种情况将其递归称为 findID 函数,使用元素的subs作为列表。如果找到一个元素,则返回其ID,否则迭代会继续。

假设每个标题在数组中都是唯一的。
否则只会找到第一个。

看以下

function findId(title, list) {
  for (const _item of list) {
    if (_item.title === title) {
      // Return some top-level id
      return _item.id;
      
    // If the item is not the one, check if it has subs
    } else if (_item?.subs) { 
    
      // Use _item.subs as a list, calling the function recursively
      const subId = findId(title, _item.subs);
      
      // Return some nested subId if found
      if (subId !== undefined) return subId;
    }
  }
  // Return undefined if not found
  return undefined;
}


var myData = [
{
    id: 0,
    title: "Item 1"
  }, 
  {
    id: 1,
    title: "Item 2",
    subs: [
    {
      id: 10,
      title: "Item 2-1",
      subs: [
      {
        id: 100,
        title: "Item 2-2-1"
      }, {
        id: 110,
        title: "Item 2-2-2"
      }, {
        id: 120,
        title: "Item 2-2-3"
      }]
    }, {
      id: 11,
      title: "Item 2-2"
    }, {
      id: 12,
      title: "Item 2-3"
    }]
  }, 
  {
    id: 2,
    title: "Item 3"
  },
  // more data here
];

console.log("Id: ", findId("Item 2", myData));
console.log("Id: ", findId("Item 2-1", myData));
console.log("Id: ", findId("Item 2-2-2", myData));
console.log("Id: ", findId("Wrong Title", myData));
console.log("Id: ", findId("Item 2", myData));<br/>
console.log("Id: ", findId("Item 2-1", myData));<br/>
console.log("Id: ", findId("Item 2-2-2", myData));<br/>
console.log("Id: ", findId("Wrong Title", myData));<br/>

最后一个返回未定义的,因为该标题不包括在数组中。

I made this simple findId method in order to find the title and returns the id or undefined as result made for your data array structure.

findId(title, list) function.
Its purpose is to iterate the list received in the second parameter, look for the title in each element and if there is a match it returns the id, otherwise it checks if there are subs in the element and in that case it is called recursively the findId function using the subs of the element as a list. If an element is found, its id is returned, otherwise the iteration continues.

This will work fine, assuming each title is unique in the array.
Otherwise only the first will be found.

Take a look at the following

function findId(title, list) {
  for (const _item of list) {
    if (_item.title === title) {
      // Return some top-level id
      return _item.id;
      
    // If the item is not the one, check if it has subs
    } else if (_item?.subs) { 
    
      // Use _item.subs as a list, calling the function recursively
      const subId = findId(title, _item.subs);
      
      // Return some nested subId if found
      if (subId !== undefined) return subId;
    }
  }
  // Return undefined if not found
  return undefined;
}


var myData = [
{
    id: 0,
    title: "Item 1"
  }, 
  {
    id: 1,
    title: "Item 2",
    subs: [
    {
      id: 10,
      title: "Item 2-1",
      subs: [
      {
        id: 100,
        title: "Item 2-2-1"
      }, {
        id: 110,
        title: "Item 2-2-2"
      }, {
        id: 120,
        title: "Item 2-2-3"
      }]
    }, {
      id: 11,
      title: "Item 2-2"
    }, {
      id: 12,
      title: "Item 2-3"
    }]
  }, 
  {
    id: 2,
    title: "Item 3"
  },
  // more data here
];

console.log("Id: ", findId("Item 2", myData));
console.log("Id: ", findId("Item 2-1", myData));
console.log("Id: ", findId("Item 2-2-2", myData));
console.log("Id: ", findId("Wrong Title", myData));
console.log("Id: ", findId("Item 2", myData));<br/>
console.log("Id: ", findId("Item 2-1", myData));<br/>
console.log("Id: ", findId("Item 2-2-2", myData));<br/>
console.log("Id: ", findId("Wrong Title", myData));<br/>

The last one returns undefined as intended, since the title is not included in the array.

模板通常在标题中使用,因为编译器需要根据模板参数给出/推论的参数实例化代码的不同版本,并且更容易(作为程序员)让编译器多次重新编译相同的代码并稍后进行。 。
请记住,模板不能直接表示代码,而是该代码多个版本的模板。
当您在 .cpp 文件中编译非模板函数时,您正在编译混凝土函数/类。
模板不是这种情况,可以用不同类型实例化,即,在用混凝土类型替换模板参数时,必须发出具体代码。

导出关键字有一个功能,该功能用于单独编译。
导出功能在 c ++ 11 和afaik中弃用,只有一个编译器实现了它。
您不应使用导出
c ++ c ++ 11 中不可能单独汇编,但也许在 c ++ 17 中,如果概念进入,我们可以拥有某种单独汇编的方式。

为了实现单独的汇编,必须进行单独的模板身体检查。
看来可以解决概念的解决方案。
看看这个最近呈现在
标准委员会会议。
我认为这不是唯一的要求,因为您仍然需要在用户代码中实例化模板代码的代码。

我猜想模板的单独汇编问题也是一个问题,该问题正在迁移到模块,这是当前正在使用的问题。

编辑:截至2020年8月起,模块已经成为C ++的现实: https://en.cppreference .com/w/cpp/语言/模块

Templates are often used in headers because the compiler needs to instantiate different versions of the code, depending on the parameters given/deduced for template parameters, and it's easier (as a programmer) to let the compiler recompile the same code multiple times and deduplicate later.
Remember that a template doesn't represent code directly, but a template for several versions of that code.
When you compile a non-template function in a .cpp file, you are compiling a concrete function/class.
This is not the case for templates, which can be instantiated with different types, namely, concrete code must be emitted when replacing template parameters with concrete types.

There was a feature with the export keyword that was meant to be used for separate compilation.
The export feature is deprecated in C++11 and, AFAIK, only one compiler implemented it.
You shouldn't make use of export.
Separate compilation is not possible in C++ or C++11 but maybe in C++17, if concepts make it in, we could have some way of separate compilation.

For separate compilation to be achieved, separate template body checking must be possible.
It seems that a solution is possible with concepts.
Take a look at this paper recently presented at the
standards committee meeting.
I think this is not the only requirement, since you still need to instantiate code for the template code in user code.

The separate compilation problem for templates I guess it's also a problem that is arising with the migration to modules, which is currently being worked.

EDIT: As of August 2020 Modules are already a reality for C++: https://en.cppreference.com/w/cpp/language/modules

为什么仅在标题文件中实现模板?

    linehigh=line.new(bar_index-lasthighbarindex,h,bar_index,h,color=color.red)
    linelow=line.new(bar_index-lastlowbarindex,l,bar_index,l,color=color.green)
    line.delete(id=linehigh[1])
    line.delete(id=linelow[1])

If we are going to plot the triangles for only last high and low, then we will have to delete them too when new high/low occurs and it is not possible to delete shapes using pinescript. We can only delete lines and boxes etc. So here I have done a version where you can click a checkbox to show line for latest pivot high lows and uncheck to see how it was previously

//@version=5
indicator("test",overlay=true)
lb = input(defval=5, title='Left Bars')
rb = input(defval=5, title='Right Bars')
showlastonly=input(defval=false)
mb = lb + rb + 1

var lasthighbarindex=0
var lastlowbarindex=0
var h=0.0
var l=0.0

highestbars_1 = ta.highestbars(mb)
plotshape((not showlastonly) and (highestbars_1 == -lb), title='Triangle Pivot High', style=shape.triangledown, location=location.abovebar, color=color.new(color.red, 60), size=size.tiny, offset=-lb)
if (highestbars_1 == -lb)
    lasthighbarindex:=lb
    h:=high[lb]
else
    lasthighbarindex:=lasthighbarindex+1
lowestbars_1 = ta.lowestbars(mb)
plotshape((not showlastonly) and (lowestbars_1 == -lb), title='Triangle Pivot Low', style=shape.triangleup, location=location.belowbar, color=color.new(color.green, 60), size=size.tiny, offset=-lb)
if (lowestbars_1 == -lb)
    lastlowbarindex:=lb
    l:=low[lb]
else
    lastlowbarindex:=lastlowbarindex+1
if showlastonly and barstate.islast
    linehigh=line.new(bar_index-lasthighbarindex,h,bar_index,h,color=color.red)
    linelow=line.new(bar_index-lastlowbarindex,l,bar_index,l,color=color.green)
    line.delete(id=linehigh[1])
    line.delete(id=linelow[1])

我不确定是否有一种干净的方法可以做到这一点,因为字符串非常非归一化。最清洁的方法可能是要缩小正在修改的数据并确定可识别的模式,以便您可以将数据集的大小减少到一组较小的高度无标准字符串。

作为一个类似的示例:

UPDATE table 
   SET DATE = CASE WHEN DATE LIKE '^alnum+, digit+

在操作完成后将旧列丢弃时,将其重命名为新列并将其重命名为新列,或者如果当前表是有效的,则可以将其命名为可查询作为更新记录可能会锁定表。

THEN DATE_FORMAT(STR_TO_DATE(DATE,'%M %d, %Y'), '%Y-%m-%d') ELSE DATE END, DATE = CASE WHEN DATE LIKE '^alnum+:alnum+

在操作完成后将旧列丢弃时,将其重命名为新列并将其重命名为新列,或者如果当前表是有效的,则可以将其命名为可查询作为更新记录可能会锁定表。

THEN DATE_FORMAT(STR_TO_DATE(DATE,'%M %d %l:%i %p'), '%m-%d') ELSE DATE END;

在操作完成后将旧列丢弃时,将其重命名为新列并将其重命名为新列,或者如果当前表是有效的,则可以将其命名为可查询作为更新记录可能会锁定表。

I'm not sure there is a clean way to do this since strings are very much non normalized. The cleanest approach would likely be to chunk the data being modified and identify patterns that are identifiable so that you can reduce the size of the dataset to a smaller group of highly unnormalized strings.

As an example something similar to this:

UPDATE table 
   SET DATE = CASE WHEN DATE LIKE '^alnum+, digit+

It might help to create this as a new column and rename the new column when dropping the old one once the operation is complete or creating this as a new table if the current table is live and needs to be queryable as updating records may lock the table.

THEN DATE_FORMAT(STR_TO_DATE(DATE,'%M %d, %Y'), '%Y-%m-%d') ELSE DATE END, DATE = CASE WHEN DATE LIKE '^alnum+:alnum+

It might help to create this as a new column and rename the new column when dropping the old one once the operation is complete or creating this as a new table if the current table is live and needs to be queryable as updating records may lock the table.

THEN DATE_FORMAT(STR_TO_DATE(DATE,'%M %d %l:%i %p'), '%m-%d') ELSE DATE END;

It might help to create this as a new column and rename the new column when dropping the old one once the operation is complete or creating this as a new table if the current table is live and needs to be queryable as updating records may lock the table.

G1 Young阶段包括两个停止世界步骤(标记和清理)。它还包括一些并发的步骤(并发启动)。

因此,我会回答您的问题:是的,年轻的收集停止/停止了您的应用程序。

You can check G1 specifics

G1 Young phase includes two stop-the-world steps (marking and cleanup). It also includes some steps (Concurrent Start) which are concurrent.

So I would answer your question: yes, Young Collection halts/stop-the-world your application.

Using such way of path extension make your code less understandable. (maybe you should read more about RESTful API) But spring can do almost everything you want.

    }

    public static void main(String[] args) {

我在环境中也有同样的错误。我刚刚跟随此 官方文件 并完成了repro,现在对我来说很好。您可以按照以下代码解决您的问题。

示例代码:

from pyspark.sql import SparkSession
account_name = 'your_blob_name'
container_name = 'your_container_name'
relative_path = 'your_folder path'
linked_service_name = 'Your_linked_service_name'

sas_token = mssparkutils.credentials.getConnectionStringOrCreds(linked_service_name)

访问blob存储

path = 'wasbs://%s@%s.blob.core.windows.net/%s' % (container_name,account_name,relative_path)   
spark.conf.set('fs.azure.sas.%s.%s.blob.core.windows.net' % (container_name,account_name),sas_token)
